BIOLASE TECHNOLOGY, INC.

PROSPECTUS SUMMARY

In this prospectus, the terms “BIOLASE,” “our company,” “we,” “our,” and “us” refer to BIOLASE Technology, Inc. and its subsidiaries.

Our Business

We are a medical technology company that develops, manufactures and markets lasers and related products focused on technologies for improved applications and procedures in dentistry and medicine. In particular, our principal products provide dental laser systems that allow dentists, periodontists, endodontists, oral surgeons and other specialists to perform a broad range of dental procedures, including cosmetic and complex surgical applications. Our systems are designed to provide clinically superior performance for many types of dental procedures, with less pain and faster recovery times than are generally achieved with drills, scalpels and other dental instruments. We have clearance from the U.S. Food and Drug Administration, or FDA, to market our laser systems in the United States and also have the necessary approvals to sell our laser systems in Canada, the European Union and certain other international markets.

In May 2002, our common stock was listed and began trading on the NASDAQ National Market under the symbol “BLTI.” Prior to 2002, our common stock traded on the NASDAQ SmallCap Market.

We are organized as a Delaware corporation. Our principal executive offices are located at 981 Calle Amanecer, San Clemente, California 92673, and our telephone number is (949) 361-1200. We maintain a website at www.biolase.com. Information contained in or that can be accessed through our website is not a part of this prospectus.

The Offering

In January 2005, we acquired certain patents from Diodem, LLC, or Diodem. The transaction was the result of a binding letter of intent the parties entered into in December 2004, or Binding Letter of Intent. The purchase price paid to Diodem was approximately $7.5 million, consisting of approximately $3 million in cash, 361,664 shares of our common stock issued at the closing, 45,208 shares of common stock that are held in escrow and are subject to release on or before July 2006 if certain conditions are satisfied and a five-year warrant to purchase 81,037 shares of our common stock at an exercise price of $11.06 per share. This prospectus relates to the resale of all of the 487,909 shares issued or issuable to Diodem in this transaction, including the shares issuable upon exercise of the warrant. As part of the transaction, we agreed to register the shares for resale by Diodem. The prices at which Diodem may sell the shares will be determined by the prevailing market for the shares or in negotiated transactions. Diodem subsequently assigned the 361,664 shares of common stock not held in escrow and the warrant to purchase 81,037 shares of common stock, to and among the following four parties: (i) Dovel & Luner, LLP; (ii) Lares Research; (iii) Colette Cozean; and (iv) Patrick J. Day.

FACTORS THAT MAY AFFECT OUR OPERATING RESULTS

An investment in our common stock involves significant risk. You should carefully consider the following risks and all the other information in this prospectus, in addition to other information contained in our other filings with the U.S. Securities and Exchange Commission, or SEC, before you decide to buy our common stock. Our business, financial condition and results of operations could be harmed by any of the following risks. The trading price of our common stock could decline due to any of these risks, and you could lose part or all of your investment.

Risks Relating to Our Business

Dentists and patients may be slow to adopt laser technologies, which could limit the market acceptance of our products.

Our dental laser systems represent relatively new technologies in the dental market. Currently, only a small percentage of dentists use lasers to perform dental procedures. Our future success will depend on our ability to increase demand for our products by demonstrating the potential performance advantages of our laser systems over traditional methods of treatment and over competitive laser systems to a broad spectrum of dentists and patients. Historically, we have experienced long sales cycles because dentists have been, and may continue to be, slow to adopt new technologies on a widespread basis. As a result, we generally are required to invest a significant amount of time and resources to educate customers about the benefits of our products in comparison to competing products and technologies before completing a sale, if any.

Factors that may inhibit adoption of laser technologies by dentists include cost and concerns about the safety, efficacy and reliability of lasers. For example, the selling price of our Waterlase® product is in excess of $50,000, which is substantially above the cost of competing non-laser technologies. In order to make an investment in a Waterlase product, a dentist generally would need to invest time to understand the technology, the benefits of such technology with respect to clinical outcomes and patient satisfaction, and the return on investment of the product. Absent an immediate competitive motivation, a dentist may not feel compelled to invest the time required to learn about the potential benefits of using a laser system. In addition, economic pressure, caused for example by an economic slowdown, changes in healthcare reimbursement or by competitive factors in a specific market, may make dentists reluctant to purchase substantial capital equipment or invest in new technologies. Patient acceptance will depend on the recommendations of dentists and specialists, as well as other factors, including without limitation, the relative effectiveness, safety, reliability and comfort of our systems as compared to other instruments and methods for performing dental procedures. The failure of dental lasers to achieve broad market acceptance would limit sales of our products and have an adverse effect on our business and results of operations.

Fluctuations in our revenue and operating results on a quarterly and annual basis could cause the market price of our common stock to decline.

Our revenue and operating results fluctuate from quarter to quarter due to a number of factors, many of which are beyond our control. Historically, we have experienced fluctuations in revenue from quarter to quarter due to seasonality. Revenue in the first quarter typically is lower than average and revenue in the fourth quarter typically is stronger than average due to the buying patterns of dental professionals. In addition, revenue in the third quarter may be affected by vacation patterns which can cause revenue to be flat or lower than in the second quarter of the year. Notwithstanding this pattern, in 2005, our net revenue has declined each quarter. If our quarterly revenue or operating results fall below the expectations of investors, analysts or our previously stated financial guidance, the price of our common stock could decline substantially. Factors that might cause quarterly fluctuations in our revenue and operating results include, among others, the following:

•

variation in demand for our products, including seasonality

•

our ability to research, develop, market and sell new products and product enhancements in a timely manner

•

our ability to control costs

•

our ability to control quality issues with our products

•

the size, timing, rescheduling or cancellation of orders from distributors

•

the introduction of new products by competitors

•

the length of and fluctuations in sales cycles

•

the availability and reliability of components used to manufacture our products

•

changes in our pricing policies or those of our suppliers and competitors, as well as increased price competition in general

•

the mix of our domestic and international sales and the risks and uncertainties associated with international business

•

costs associated with any future acquisitions of technologies and businesses

•

limitations on our ability to use net operating loss carryforwards under the provisions of Internal Revenue Code Section 382 and similar state laws

•

developments concerning the protection of our intellectual property rights

•

catastrophic events such as hurricanes, floods and earthquakes, which can affect our ability to advertise, sell and distribute our products, including through national conferences held in regions in which these disasters strike

•

global economic, political and social events, including international conflicts and acts of terrorism

The expenses we incur are based, in large part, on our expectations regarding future net revenue. In particular, we expect to continue to incur substantial expenses relating to the marketing and promotion of our products. Since many of our costs are fixed in the short term, we may be unable to reduce expenses quickly enough to avoid losses if we experience a decrease in net revenue. Accordingly, you should not rely on quarter-to-quarter comparisons of our operating results as an indication of our future performance.

We may have difficulty achieving profitability and may experience additional losses.

We recorded a net loss of $16.3 million for the nine months ended September 30, 2005, due partly to our professional fees related to the 2004 audit and restated financial statements and our compliance with the Sarbanes-Oxley Act, $2.0 million related to the purchase of a license to use certain patent rights from Surgilight, including the transaction costs and increased expenses as a result of quality issues with our products that we are addressing. We also experienced a loss in fiscal 2004 of $23.2 million, of which $14.4 million was attributable to the recording of a valuation allowance associated with our deferred tax assets. In order to achieve profitability, we must control our costs and increase net revenue through new sales. Failure to increase our net revenue and decrease our costs could cause our stock price to decline.

Any failure to significantly expand sales of our products will negatively impact our business.

We currently handle a majority of the marketing, distribution and sales of our products. In order to achieve our business objectives, we intend to significantly expand our marketing and sales efforts on a domestic and international basis. We face significant challenges and risks in expanding, training, managing and retaining our sales and marketing teams, including managing geographically dispersed operations. In addition, we rely on independent distributors to market and sell our products in a number of countries outside of the United States. These distributors may not commit the necessary resources to effectively market and sell our products, and they may terminate their relationships with us at any time with limited notice. If we are unable to expand our sales and marketing capabilities domestically and internationally, we may not be able to effectively commercialize our products, which could harm our business and cause the price of our common stock to decline.

Components used in our products are complex in design and any defects may not be discovered prior to shipment to customers, which could result in warranty obligations, reducing our revenue and increasing our cost.

In manufacturing our products, we depend upon third parties for the supply of various components. Many of these components require a significant degree of technical expertise to design and produce. If we fail adequately to design or if our suppliers fail to produce components to specification, or if the suppliers, or we, use defective materials or workmanship in the manufacturing process, the reliability and performance of our products will be compromised. We have experienced such non-compliance with manufacturing specifications in the past and may continue to experience such in the future, which could lead to higher costs of revenue and thus reduced gross margins.

Our products may contain defects that cannot be repaired easily and inexpensively, and we have experienced in the past and may experience in the future some or all of the following:

•

loss of customer orders and delay in order fulfillment

•

damage to our brand reputation

•

increased cost of our warranty program due to product repair or replacement

•

inability to attract new customers

•

diversion of resources from our manufacturing and research and development departments into our service department

•

legal action

The occurrence of any one or more of the foregoing could materially harm our business.

Our distributors may cancel, reduce or delay orders of our products, any of which could reduce our revenue.

We employ direct sales representatives in certain European countries; however, we rely on independent distributors for a substantial portion of our sales outside of the United States. For the year ended December 31, 2004, revenue to distributors accounted for approximately 13% of our total sales, and no distributor accounted for more than 10% of our revenue. For the nine months ended September 30, 2005, net revenue to distributors accounted for approximately 16% of our total sales, and no distributor accounted for more than 10% of our net revenue. Our ability to maintain or increase our net revenue will depend in large part on our success in developing and maintaining relationships with our distributors. The loss of a number of our distributors or a reduction in, cancellation of or change in the size or timing of orders from our distributors or any problems collecting accounts receivable from our distributors could reduce our net revenue. In addition, we may experience lengthy delays and incur substantial costs if we are required to replace distributors or retain direct sales representatives for such territories in the future.

We must continue to procure materials and components on commercially reasonable terms and on a timely basis to manufacture our products profitably. We have some single-source suppliers.

We have no written supply contracts with our key suppliers; instead, we purchase certain materials and components included in our products from a limited group of suppliers using purchase orders. Our business depends in part on our ability to obtain timely deliveries of materials and components in acceptable quality and quantities from our suppliers. Certain components of our products, particularly specialized components used in our lasers, are currently available only from a single source or limited sources. For example, the crystal, fiber and hand pieces used in our Waterlase system are each supplied by a separate single supplier and from time to time we have experienced quality deficiencies in these materials. Unexpected interruptions in a single source supplier or quality problems in products we received from a supplier create manufacturing delays or product failures, disrupt sales and cause additional expense relating to the procurement of another supplier as well as adversely

impact our cost of revenue. We may not be successful in managing any shortage, delay of, or quality control issues with respect to materials or components that we experience, and any such event could cause our business and results of operations to suffer. In particular, our gross margins for the nine months ended September 30, 2005 have been adversely impacted by higher manufacturing costs as a result of quality issues in parts supplied by third parties.

We may not be able to compete successfully, which will cause our revenue and market share to decline.

We compete with a number of domestic and foreign companies that market traditional dental products, such as dental drills, as well as companies that market laser technologies in the dental and medical markets, including Hoya ConBio, a subsidiary of Hoya Photonics, OpusDent Ltd., a subsidiary of Lumenis, KaVo, Deka Dental Corporation, Ivoclar Vivadent AG, and Fotona d.d. If we do not compete successfully, our revenue and market share may decline. Some of our competitors have greater financial, technical, marketing or other resources than we have, which may allow them to respond more quickly to new or emerging technologies and to devote greater resources to the acquisition or development and introduction of enhanced products than we can. The ability of our competitors to devote greater financial resources to product development requires us to work harder to distinguish our products through improving our product performance and pricing, protecting our intellectual property, continuously improving our customer support, accurately timing the introduction of new products and developing sustainable distribution channels worldwide. In addition, we expect the rapid technological changes occurring in the healthcare industry to lead to the entry of new competitors, particularly if dental and medical lasers gain increasing market acceptance. We must be able to anticipate technological changes and introduce enhanced products on a timely basis in order to grow and remain competitive. New competitors or technological changes in laser products and methods could cause commoditization of our products, require price discounting or otherwise adversely affect our gross margins and our financial condition.

Rapidly changing standards and competing technologies could harm demand for our products or result in significant additional costs.

The markets in which our products compete are subject to rapid technological change, evolving industry standards, changes in the regulatory environment, and frequent introductions of new devices and evolving dental and surgical techniques. Competing products may emerge which could render our products uncompetitive or obsolete. The process of developing new medical devices is inherently complex and requires regulatory approvals or clearances that can be expensive, time consuming and uncertain. We cannot guarantee that we will successfully identify new product opportunities, identify new and innovative applications of our technology, or be financially or otherwise capable of completing the research and development required to bring new products to market in a timely manner. An inability to expand our product offerings or the application of our technology could limit our growth. In addition, we may incur higher manufacturing costs if manufacturing processes or standards change, and we may need to replace, modify, design or build and install equipment, all of which would require additional capital expenditures.

If we are unable to attract and retain personnel necessary to operate our business, our ability to develop and market our products successfully could be harmed.

We are heavily dependent on our current executive officers and management. The loss of any key employee or the inability to attract or retain qualified personnel, including engineers and sales and marketing personnel, could delay the development and introduction of, and harm our ability to sell our products and harm our reputation. We believe that our future success is highly dependent on the contributions of Robert E. Grant, our President and Chief Executive Officer, Jeffrey W. Jones, our Chief Technology Officer and Richard L. Harrison, our Executive Vice President and Chief Financial Officer. We have employment agreements with each of these individuals that provide us with the ability to terminate their employment at will, subject to certain severance rights; however, their knowledge of our business and industry would be extremely difficult to replace. Our future success also depends on our ability to attract and retain additional qualified management, engineering, sales and marketing, and other highly skilled technical personnel.

Any problems that we experience with our manufacturing operations may harm our business.

We manufacture our products at our California and German facilities. In order to grow our business, we must significantly expand our manufacturing capabilities to produce the systems and accessories necessary to meet any demand we may experience. We may encounter difficulties in increasing production of our products, including problems involving production capacity and yields, quality control and assurance, component supply and shortages of qualified personnel. In addition, our manufacturing facilities are subject to periodic inspections by the U.S. Food and Drug Administration, or the FDA, as well as various state agencies and foreign regulatory agencies. Our success will depend in part upon our ability to manufacture our products in compliance with the FDA’s Quality System regulations and other regulatory requirements. We recently have experienced quality issues with components of our products supplied by third parties. If we do not succeed in manufacturing our products on a timely basis and with acceptable manufacturing costs while at the same time maintaining good quality control and complying with applicable regulatory requirements, our business will be harmed.

Changes in government regulation or the inability to obtain or maintain necessary government approvals could harm our business.

Our products are subject to extensive government regulation, both in the United States and in other countries. To clinically test, manufacture and market products for human use, we must comply with regulations and safety standards set by the FDA and comparable state and foreign agencies. Regulations adopted by the FDA are wide ranging and govern, among other things, product design, development, manufacture and testing, labeling, storage, advertising and sales. Generally, products must meet regulatory standards as safe and effective for their intended use before being marketed for human applications. The clearance process is expensive, time-consuming and uncertain. Failure to comply with applicable regulatory requirements of the FDA can result in an enforcement action which may include a variety of sanctions, including fines, injunctions, civil penalties, recall or seizure of our products, operating restrictions, partial suspension or total shutdown of production and criminal prosecution. The failure to receive or maintain requisite approvals for the use of our products or processes, or significant delays in obtaining such approvals, could prevent us from developing, manufacturing and marketing products and services necessary for us to remain competitive. In addition, unanticipated changes in existing regulatory requirements or the adoption of new requirements could impose significant costs and burdens on us, which could increase our operating expenses and harm our financial condition.

Regulatory proceedings relating to the restatement of our consolidated financial statements could divert management’s attention and resources.

We restated our previously issued financial statements in September of 2003 to reflect a change in the timing of revenue recognition for the fiscal years 2000 through 2002 and the quarters ended March 31, 2002 through March 31, 2003. In addition, in July 2005 we restated our consolidated financial statements for the 2002 and 2003 fiscal years, the four quarters of 2003 and the first three fiscal quarters of 2004 due to a number of factors discussed in Note 3 to our audited consolidated financial statements included in our Form 10-K for the year ended December 31, 2004 and included elsewhere in this prospectus. We received informal requests from the SEC voluntarily to provide information relating to the September 2003 restatement of our consolidated financial statements. We provided information to the SEC and if we receive any additional requests for information, we intend to continue to do so. In accordance with its normal practice, the SEC has not advised us when its inquiry might be concluded. If the SEC elects to request additional information from us or commences further proceedings, including as a result of our recent restatement, responding to such requests or proceedings could divert management’s attention and resources. Additionally, any negative developments arising from such requests or proceedings could harm our business and cause the price of our common stock to decline.

We may have difficulty managing any growth that we might experience.

If we experience growth in our operations, our operational and financial systems, procedures and controls may need to be expanded, which will place significant demands on our management, distract management from

our business plan and increase expenses. Our success will depend substantially on the ability of our management team to manage any growth effectively. These challenges may include, among others:

•

maintaining our cost structure at an appropriate level based on the revenue we generate

•

managing manufacturing expansion projects

•

implementing and improving our operational and financial systems, procedures and controls

•

managing operations in multiple locations and multiple time zones

In addition, we incur significant legal, accounting, insurance and other expenses as a result of being a public company. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and NASDAQ, has required changes in corporate governance practices of public companies. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly. We also expect these rules and regulations to make it more difficult and more expensive for us to maintain director and officer insurance and, from time to time, we may be required to accept reduced policy limits and coverage or incur significantly higher costs to maintain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. We continue to evaluate and monitor developments with respect to these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

If we fail to secure or protect our intellectual property rights, competitors may be able to use our technologies, which could weaken our competitive position, reduce our revenue or increase our costs.

Our future success will depend, in part, on our ability to obtain and maintain patent protection for our products and technology, to preserve our trade secrets and to operate without infringing the intellectual property of others. We rely on patents to establish and maintain proprietary rights in our technology and products. We currently possess a number of issued patents and patent applications with respect to our products and technology; however, we cannot assure that any additional patents will be issued, that the scope of any patent protection will be effective in helping us address our competition or that any of our patents will be held valid if subsequently challenged. It is also possible that our competitors may independently develop similar products, duplicate our products or design products that circumvent our patents. Additionally, the laws of foreign countries may not protect our products or intellectual property rights to the same extent as the laws of the United States. If we fail to protect our intellectual property rights adequately, our competitive position and financial condition may be harmed.

We may be sued by third parties for alleged infringement of their proprietary rights.

We face substantial uncertainty regarding the impact that other parties’ intellectual property positions will have on the markets for dental and other medical lasers. The medical technology industry has in the past been characterized by a substantial amount of litigation and related administrative proceedings regarding patents and intellectual property rights. From time to time, we have received, and expect to continue to receive, notices of claims of infringement, misappropriation or misuse of other parties’ proprietary rights. Some of these claims may lead to litigation. We may not prevail in any future intellectual property infringement litigation given the complex technical issues and inherent uncertainties in litigation. Any claims, with or without merit, may be time-consuming and distracting to management, result in costly litigation or cause product shipment delays. Adverse determinations in litigation could subject us to significant liability and could result in the loss of proprietary rights. A successful lawsuit against us could also force us to cease selling or redesign products that incorporate the infringed intellectual property. Additionally, we could be required to seek a license from the holder of the intellectual property to use the infringed technology, and it is possible that we may not be able to obtain a license on acceptable terms, or at all. Any of the foregoing adverse events could seriously harm our business.

We have significant international sales and are subject to risks associated with operating in international markets.

International sales comprise a significant portion of our net revenue and we intend to continue to pursue and expand our international business activities. For the fiscal year 2004, international sales accounted for approximately 19% of our net revenue, as compared to approximately 20% of our net revenue in fiscal year 2003 and approximately 23% of our net revenue in fiscal year 2002. For the nine months ended September 30, 2005, international sales accounted for approximately 28% of our net revenue, as compared to approximately 27% of our net revenue for the same period in 2004. Political and economic conditions outside the United States could make it difficult for us to increase our international revenue or to operate abroad. International operations, including our operations in Germany, are subject to many inherent risks, including among others:

•

adverse changes in tariffs and trade restrictions

•

political, social and economic instability and increased security concerns

•

fluctuations in foreign currency exchange rates

•

longer collection periods and difficulties in collecting receivables from foreign entities

•

exposure to different legal standards

•

transportation delays and difficulties of managing international distribution channels

•

reduced protection for our intellectual property in some countries

•

difficulties in obtaining domestic and foreign export, import and other governmental approvals, permits and licenses and compliance with foreign laws

•

the imposition of governmental controls

•

unexpected changes in regulatory or certification requirements

•

difficulties in staffing and managing foreign operations

•

potentially adverse tax consequences and the complexities of foreign value-added tax systems

We believe that international sales will continue to represent a significant portion of our net revenue, and we intend to expand our international operations further. Our direct net revenue in Europe is denominated principally in Euros, while our net revenue in other international markets is in U.S. dollars. As a result, an increase in the relative value of the dollar against the Euro would lead to less income from sales denominated in Euros, unless we increase prices, which may not be possible due to competitive conditions in Europe. We could experience losses from European transactions if the relative value of the dollar were to increase in the future. We do not currently engage in any transactions as a hedge against risks of loss due to foreign currency fluctuations, although we may consider doing so in the future.

Net revenue generated from products manufactured at our German facility accounted for 12% of our net revenue for the nine months ended September 30, 2005 and 8% of our net revenue for the comparable period in fiscal year 2004. Expenses relating to our manufacturing operations in Germany are paid in Euros; therefore, an increase in the value of the Euro relative to the dollar would increase the expenses associated with our German manufacturing operations and reduce our earnings. In addition, we may experience difficulties associated with managing our operations remotely and complying with German regulatory and legal requirements for maintaining our manufacturing operations in that country. Any of these factors may adversely affect our future international revenue and manufacturing operations and, consequently, negatively impact our business and operating results. We are currently reviewing our need for manufacturing in Germany and may in the future decrease or eliminate our manufacturing operations there. However, we would retain our ability to manufacture our products in Germany.

We may not address successfully problems encountered in connection with any future acquisition.

We expect to continue to consider opportunities to acquire or make investments in other technologies, products and businesses that could enhance our capabilities, complement our current products or expand the breadth of our markets or customer base. We have limited experience in acquiring other businesses and technologies. Potential and completed acquisitions and strategic investments involve numerous risks, including, among others:

•

problems assimilating the purchased technologies, products or business operations

•

problems maintaining uniform standards, procedures, controls and policies

•

unanticipated costs associated with the acquisition

•

diversion of management’s attention from our core business

•

adverse effects on existing business relationships with suppliers and customers

•

risks associated with entering new markets in which we have no or limited prior experience

•

potential loss of key employees of acquired businesses

•

increased legal and accounting costs as a result of the rules and regulations related to the Sarbanes-Oxley Act of 2002

If we fail to properly evaluate and execute acquisitions and strategic investments, our management team may be distracted from our day-to-day operations, our business may be disrupted and our operating results may suffer. In addition, if we finance acquisitions by issuing equity or convertible debt securities, our stockholders would be diluted.

If our customers cannot obtain third party reimbursement for their use of our products, they may be less inclined to purchase our products.

Our products are generally purchased by dental or medical professionals who have various billing practices and patient mixes. Such practices range from primarily private pay to those who rely heavily on third party payors, such as private insurance or government programs. In the United States, third party payors review and frequently challenge the prices charged for medical services. In many foreign countries, the prices for dental services are predetermined through government regulation. Payors may deny coverage and reimbursement if they determine that the procedure was not medically necessary, such as a cosmetic procedure, or that the device used in the procedure was investigational. We believe that most of the procedures being performed with our current products generally are reimbursable, with the exception of cosmetic applications, such as tooth whitening. For the portion of dentists who rely heavily on third party reimbursement, the inability to obtain reimbursement for services using our products could deter them from purchasing or using our products. We cannot predict the effect of future healthcare reforms or changes in financing for health and dental plans. Any such changes could have an adverse effect on the ability of a dental or medical professional to generate a return on investment using our current or future products. Such changes could act as disincentives for capital investments by dental and medical professionals and could have a negative impact on our business and results of operations.

We are party to securities and derivative litigation that distracts our management, is expensive to conduct and seeks a damage award against us.

We and certain of our current and former officers have been named as defendants in several putative shareholder class action lawsuits filed in the United States District Court for the Central District of California. The complaints purport to seek unspecified damages on behalf of an alleged class of persons who purchased our common stock between October 29, 2003 and July 16, 2004. The complaints allege that we and our officers violated federal securities laws by failing to disclose material information about the demand for our products and the fact that we would not achieve the alleged forecasted growth. The claimed misrepresentations include certain

statements in our press releases and the registration statement we filed in connection with our public offering of stock which closed in March 2004. In addition, three stockholders have filed derivative actions in the state court in California seeking recovery on behalf of BIOLASE, alleging, among other things, breach of fiduciary duties by those individual defendants and members of our board of directors. The second amended complaint was dismissed without prejudice in January 2006, and the court gave the plaintiffs 30 days to amend their complaint. This litigation presents a distraction to our management, is expensive to conduct, and if we are unsuccessful in defending this litigation, may result in damage awards against us that would harm our financial condition and operating results.

Material increases in interest rates may harm our sales.

We currently sell our products primarily to dentists in general practice. These dentists often purchase our products with funds they secure through various financing arrangements with third party financial institutions, including credit facilities and short-term loans. If interest rates continue to increase, these financing arrangements will be more expensive to our dental customers, which would effectively increase the overall cost of owning our products for our customers and, thereby, may decrease demand for our products. Any reduction in the sales of our products would cause our business to suffer.

Product liability claims against us could be costly and could harm our reputation.

The sale of dental and medical devices involves the inherent risk of product liability claims against us. We currently maintain product liability insurance on a per occurrence basis with a limit of $11.0 million per occurrence and $12.0 million in the aggregate for all occurrences. The insurance is subject to various standard coverage exclusions, including damage to the product itself, losses from recall of our product and losses covered by other forms of insurance such as workers compensation. We cannot be certain that we will be able to successfully defend any claims against us, nor can we be certain that our insurance will cover all liabilities resulting from such claims. In addition, there is no assurance that we will be able to obtain such insurance in the future on terms acceptable to us, or at all. Any product liability claims brought against us could harm our reputation and cause our business to suffer.

Our ability to use net operating loss carryforwards may be limited.

Section 382 of the Internal Revenue Code of 1986 generally imposes an annual limitation on the amount of net operating loss carryforwards that may be used to offset taxable income when a corporation has undergone significant changes in its stock ownership. In 2003, we completed an analysis to determine the applicability of the annual limitations imposed by Section 382 caused by previous changes in our stock ownership and determined that such limitations should not be significant. Based on our analysis, we believe that, as of December 31, 2004, approximately $39.0 million of net operating loss carryforwards were available to us for federal income tax purposes. Of this amount, approximately $34.5 million is available to offset federal taxable income or the taxable income generated in 2005 or in future years, if any. Additional net operating loss carryforwards will become available at the rate of approximately $1.0 million per year for the years 2005 through 2009. However, any ownership changes qualifying under Section 382 including changes resulting from or affected by our public offering or our stock repurchase plan may adversely affect our ability to use our remaining net operating loss carryforwards. If we lose our ability to use net operating loss carryforwards, any income we generate will be subject to tax earlier than it would be if we were able to use net operating loss carryforwards, resulting in lower profits.

Our business is capital intensive and the failure to obtain capital could require that we curtail capital expenditures.

To remain competitive, we must continue to make significant investments in the development of our products, the expansion of our sales and marketing activities and the expansion of our operating and management infrastructure as we increase sales domestically and internationally. We expect that substantial capital will be required to expand our operations and fund working capital for anticipated growth. We may need to raise

additional funds through further debt or equity financings, which may affect the percentage ownership of existing holders of common stock and which may have rights, preferences or privileges senior to those of the holders of our common stock or may be issued at a discount to the market price of our common stock thereby resulting in dilution to our existing stockholders. We may not be able to raise additional capital on reasonable terms, or at all. If we cannot raise the required capital when needed, we may not be able to satisfy the demands of existing and prospective customers and may lose revenue and market share.

The following factors among others could affect our ability to obtain additional financing on favorable terms, or at all:

•

our results of operations

•

general economic conditions and conditions in the electronics industry

•

the perception of our business in the capital markets

•

our ratio of debt to equity

•

our financial condition

•

our business prospects

•

interest rates

If we are unable to obtain sufficient capital in the future, we may have to curtail our capital expenditures. Any curtailment of our capital expenditures could result in a reduction in net revenue, reduced quality of our products, increased manufacturing costs for our products, harm to our reputation, reduced manufacturing efficiencies or other harm to our business.

We have adopted anti-takeover defenses that could delay or prevent an acquisition of our company and may affect the price of our common stock. Certain provisions of our certificate of incorporation, and the existence of our stockholder rights plan, could make it difficult for any party to acquire us, even though an acquisition might be beneficial to our stockholders, and could limit the price that investors might be willing to pay in the future for shares of our common stock.

In December 1998, we adopted a stockholder rights plan pursuant to which one preferred stock purchase right was distributed to our stockholders for each share of our common stock held. In connection with the stockholder rights plan, the Board of Directors has designated 500,000 shares of Series B Junior Participating Cumulative Preferred Stock. If any party acquires 15% or more of our outstanding common stock while the stockholder rights plan remains in place (i.e., if such party does not negotiate with the Board of Directors, which has the power to redeem the rights and terminate the plan), the holders of these rights (other than the party acquiring the 15% position) will be able to purchase shares of our common stock (or other securities or assets) at a discounted price, causing substantial dilution to the party acquiring the 15% position. Following the acquisition of 15% or more of our stock by any person (without a redemption of the rights or a termination of the stockholder rights plan by the Board of Directors), if we are acquired by or merged with any other entity, holders of these rights (other than the party acquiring the 15% position) will also be able to purchase shares of common stock of the acquiring or surviving entity if the stockholder rights plan continues to remain in place.

In addition, under our certificate of incorporation, the Board of Directors has the power to authorize the issuance of up to 500,000 shares of preferred stock that is currently undesignated, and to designate the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without further vote or action by the stockholders. Accordingly, our Board of Directors may issue preferred stock with terms that could have preference over and adversely affect the rights of holders of our common stock. The issuance of any such preferred stock may:

•

delay, defer or prevent a change in control of our company

•

adversely affect the voting and other rights of the holders of our common stock

•

discourage acquisition proposals or tender offers for our shares without the advance approval of the Board of Directors, including bids at a premium over the market price for our common stock

Our common stock could be diluted by the conversion of outstanding convertible securities.

We have issued and will continue to issue outstanding convertible securities in the form of options and warrants as incentive compensation for services performed by our employees, directors, consultants and others. As of September 15, 2005 we had options to purchase 3,682,000 shares of our common stock outstanding, of which options to purchase 2,648,000 shares of common stock were exercisable. In addition, we have issued warrants to purchase an aggregate of 81,037 shares of common stock at an exercise price of $11.06 per share, which shares are being registered for resale in the registration statement of which this prospectus forms a part. If these options or warrants were exercised, it would dilute the ownership of our stock and could adversely affect our common stock’s market price.

Our financial outlook could be affected by changes in the accounting rules which govern the recognition of stock-based compensation expenses.

We measure compensation expense for our employee stock compensation plans under the intrinsic value method of accounting prescribed by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees.” Under this method, we recognized no compensation charges related to stock compensation plans because the exercise price of all options granted under these plans was equal to the fair market value of the underlying common stock on the grant date, and therefore no stock-based employee compensation cost is recognized in the consolidated statements of operations. The Financial Accounting Standards Board has announced changes to accounting rules concerning the recognition of stock option compensation expense. Beginning in the first quarter of fiscal 2006 when these changes are expected to be implemented, we and other companies will be required to measure compensation expense using the fair value method, which will adversely affect our results of operations by increasing our compensation expenses by the additional amount of such stock option charges.

Our internal controls and procedures need to be improved.

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles. In making its assessment of internal control over financial reporting as of December 31, 2004, management used the criteria described in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). A material weakness is a control deficiency, or combination of control deficiencies, that results in a more than remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

Management determined that material weaknesses in our internal control over financial reporting existed as of December 31, 2004, and these material weaknesses contributed to the restatement of our consolidated financial statements for the full 2002 fiscal year, the first, second, third and fourth quarters of 2003, the full 2003 fiscal year and the first, second and third fiscal quarters of 2004. These material weaknesses are discussed in this prospectus under the section “Management’s Discussion and Analysis—Controls and Procedures.” Because of these material weaknesses, management concluded that our internal control over financial reporting was not effective as of December 31, 2004 based on the criteria of the Internal Control—Integrated Framework issued by COSO. Further, the material weaknesses identified resulted in an adverse opinion by our independent registered public accounting firm on the effectiveness of our internal control over financial reporting. Our management also determined that we had a number of significant deficiencies as of December 31, 2004. Subsequently in 2005, we have identified an additional material weakness as a result of our internal controls not operating effectively during the nine months ended September 30, 2005 related to our inventory control.

If we are unable to substantially improve our internal controls, our ability to report our financial results on a timely and accurate basis will continue to be adversely affected, which could have a material adverse affect on our ability to operate our business. If we fail to adequately remediate our material weaknesses by the end of our fiscal year, our management will be required to conclude that our internal control over financial reporting is ineffective. In addition, if we fail to remediate our significant deficiencies in our fiscal year, our management likely will be required to conclude that those significant deficiencies are also material weaknesses. Please see the section in this prospectus called “Management’s Discussion and Analysis - Controls and Procedures” for more information regarding the status of our remedial measures with respect to the material weaknesses in our internal controls described in “Management’s Report on Internal Control over Financial Reporting.” The costs of remediating such deficiencies in our internal controls will adversely affect our results of operations. In addition, even after the remedial measures discussed in this prospectus under the section called “Management’s Discussion and Analysis—Controls and Procedures” are fully implemented, our internal control will not prevent all potential error and fraud, because any control system, no matter how well designed, can only provide reasonable and not absolute assurance that the objectives of the control system will be achieved.

Our failure to comply with certain conditions required for our common stock to be listed on the NASDAQ National Market could result in the delisting of our common stock from the NASDAQ National Market.

As a result of our failure to timely file our Annual Report on Form 10-K for the fiscal year ended December 31, 2004 and our Quarterly Reports on Forms 10-Q for the fiscal quarters ended March 31, 2005 and June 30, 2005, and certain required restatements of our financial statements for prior periods, we were not in full compliance with NASDAQ Marketplace Rule 4310(c)(14), which requires us to make, on a timely basis, all filings with the SEC required by the Securities Exchange Act of 1934. We are required to comply with NASDAQ Marketplace Rule 4310(c)(14) as a condition for our common stock to continue to be listed on the NASDAQ National Market.

In April 2005, we received a notification from NASDAQ with respect to the late Form 10-K, and in July 2005, the NASDAQ granted us an extension of time until August 1, 2005 in which to file our Form 10-K, the restatements with respect to our historical financial statements, our Form 10-Q for the first quarter ended March 31, 2005, our Form 10-Q for the second quarter ended June 30, 2005 and to otherwise meet all necessary listing standards of the NASDAQ Market. On July 19, 2005, we filed (i) our Form 10-K for the fiscal year ended December 31, 2004 which included consolidated financial statements for the year ended December 31, 2004 and restated consolidated financial statements as of December 31, 2003 and the two years then ended and (ii) Forms 10-Q/A for the fiscal quarters ended March 31, 2004, June 30, 2004 and September 30, 2004 which included restated financial statements for the prior comparative periods as well. In July 2005, we requested an additional extension of time from NASDAQ in which to file our Form 10-Q for the fiscal quarter ended March 31, 2005 and our Form 10-Q for the second quarter ended June 30, 2005. In August 2005, we received additional notices from NASDAQ regarding the late filing of the first quarter Form 10-Q and granting us the requested extension of time until September 30, 2005 in which to file both our first quarter Form 10-Q and our second quarter Form 10-Q, and to otherwise meet all necessary listing standards. On September 30, 2005 we filed our Form 10-Q for the first and second quarter of 2005, and subsequently NASDAQ confirmed that we are in compliance with the continued listing requirements.

If we are unable to maintain compliance with the conditions for continued listing required by NASDAQ, then our shares of common stock are subject to delisting from the NASDAQ Market. If our shares of common stock are delisted from the NASDAQ Market, they may not be eligible to trade on any national securities exchange or the over-the-counter market. If our common stock is no longer traded through a market system, it may not be liquid, which could affect its price. In addition, we may be unable to obtain future equity financing, or use our common stock as consideration for mergers or other business combinations.

Risks Relating to This Offering

Our common stock price has been volatile, which could result in substantial losses for stockholders.

Our common stock is currently traded on the NASDAQ National Market and has limited daily trading volume. The trading price of our common stock has been and may continue to be volatile. The market for technology companies, in particular, has at various times experienced extreme volatility that often has been unrelated to the operating performance of particular companies. These broad market and industry fluctuations may significantly affect the trading price of our common stock, regardless of our actual operating performance. The trading price of our common stock could be affected by a number of factors, including, but not limited to, changes in expectations of our future performance, changes in estimates by securities analysts (or failure to meet such estimates), quarterly fluctuations in our sales and financial results and a variety of risk factors, including the ones described elsewhere in this prospectus. Periods of volatility in the market price of a company’s securities sometimes result in securities class action litigation. Such litigation would be expensive and would divert management’s attention. In addition, if we needed to raise equity funds under adverse conditions, it would be difficult to sell a significant amount of our stock without causing a significant decline in the trading price of our stock. If our stock price drops below approximately $1.00 per share for an extended period of time or we are otherwise unable to satisfy the continued listing requirements of the NASDAQ National Market, our shares could be delisted from the NASDAQ National Market and the marketability, liquidity and price of our common stock would be adversely affected.

Risks Relating to Our Industry

Changes in government regulation or the inability to obtain or maintain necessary government approvals could harm our business.

If our customers cannot obtain third party reimbursement for their use of our products, they may be less inclined to purchase our products.

the portion of dentists who rely heavily on third party reimbursement, the inability to obtain reimbursement for services using our products could deter them from purchasing or using our products. We cannot predict the effect of future healthcare reforms or changes in financing for health and dental plans. Any such changes could have an adverse effect on the ability of a dental or medical professional to generate a return on investment using our current or future products. Such changes could act as disincentives for capital investments by dental and medical professionals and could have a negative impact on our business and results of operations.

SELECTED CONSOLIDATED FINANCIAL DATA

The following selected consolidated financial data should be read in conjunction with our consolidated financial statements and related notes contained elsewhere in this prospectus, as well as the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

See Note 3 to the 2004 Consolidated Financial Statements in this prospectus for more detailed information regarding the restatement of our consolidated financial statements for the years ended December 31, 2003 and 2002.

The following discussion provides information regarding adjustments made to the previously reported consolidated financial information for the years ended December 31, 2001 and 2000:

•

Our sales tax liability was overstated as of December 31, 2001 due to inaccurate estimates of sales tax. As a result, we recorded an adjustment to decrease general and administrative expense for the sales tax liability in the amount of $78,000.

•

Our sales tax liability was understated as of December 31, 2000 due to inaccurate estimates of sales tax. As a result, we recorded an adjustment to increase general and administrative expense in the amount of $18,000.

•

We were late in filing certain sales tax returns and remitting collected amounts from customers to certain states. As a result, we recorded adjustments to increase general and administrative expense for penalties and interest in accordance with applicable state statues in the amount of $83,000 and $31,000 for the years ended December 31, 2001 and 2000, respectively.

The operating results in any period are not necessarily indicative of the results that may be expected for any future period.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

The following discussion of our results of operations and financial condition should be read together with the consolidated financial statements and the notes to those statements included elsewhere in this prospectus and other information incorporated by reference in this prospectus, if any. This discussion may contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from the results anticipated in any forward-looking statements as a result of a variety of factors, including those discussed in “Factors That May Affect Our Operating Results” and elsewhere in this prospectus.

Restatement of Financial Statements

The following discussion and analysis gives effect to the restatement discussed in Note 3 to our 2004 consolidated financial statements in this prospectus.

Overview

We are the world’s leading dental laser company. We are a medical technology company that develops, manufactures and markets lasers and related products focused on technologies for improved applications and procedures in dentistry and medicine. In particular, our principal products provide dental laser systems that allow dentists, periodontists, endodontists, oral surgeons and other specialists to perform a broad range of dental procedures, including cosmetic and complex surgical applications. Our systems are designed to provide clinically superior performance for many types of dental procedures, with less pain and faster recovery times than are generally achieved with drills, scalpels and other dental instruments. We have clearance from the U.S. Food and Drug Administration, or FDA, to market our laser systems in the United States and also have the necessary approvals to sell our laser systems in Canada, the European Union and certain other international markets. We are currently pursuing regulatory approval to market and sell our Waterlase system in Japan. Since 1998, we have sold approximately 4,000 Waterlase systems and more than 5,390 laser systems in over 45 countries.

We offer two categories of laser system products: (i) Waterlase system and (ii) Diode system. Our flagship product category, the Waterlase system, uses a patented combination of water and laser to perform most procedures currently performed using dental drills, scalpels and other traditional dental instruments for cutting soft and hard tissue. We also offer a family of Diode laser system products to perform soft tissue and cosmetic procedures, including tooth whitening.

Waterlase system. We refer to our patented interaction of water with laser as YSGG^™ Laser HydroPhotonics^™. YSGG is a shortened abbreviation referring to the unique crystal (Er, Cr: YSGG) laser used in the Waterlase, which contains the elements erbium, chromium, yttrium, scandium, gallium and garnet. This unique crystal laser produces energy with specific absorption and tissue interaction characteristics optimized for dental applications. HydroPhotonics refers to the interaction of laser with water to produce energy to cut tissue. Through YSGG Laser HydroPhotonics, the Waterlase system can precisely cut hard tissue, such as bone and teeth, and soft tissue, such as gums, with minimal or no damage to surrounding tissue. The Waterlase system is the best selling dental laser system, and we estimate it currently accounts for a majority of all dental lasers sold worldwide.

Diode system. We also offer a family of Diode system products, which use a semiconductor diode laser to perform soft tissue and cosmetic procedures, including tooth whitening. Our Diode system serves the growing markets for cosmetic and hygiene procedures.

comprised 11%, 12% and 18% of our total net revenue for the same periods. The Waterlase system comprised 83% and 81% of our net revenue for the nine months ended September 30, 2005 and 2004, respectively. The Diode system comprised 9% and 10% of our net revenue for the same periods.

Principal Factors Considered by Our Management

Among other things, in managing our business, our management is particularly focused on the following factors and considerations:

•

the need to ensure that our products are designed to meet existing and anticipated customer needs

•

the need to continuously extend our reach of technology

•

the need to leverage our intellectual property to expand our end market applications

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses for each period.

The following represents a summary of our critical accounting policies, defined as those policies that we believe are: (i) the most important to the portrayal of our financial condition and results of operations, and (ii) that require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain.

Revenue recognition. We sell products domestically to customers through our direct sales force, and internationally through a direct sales force and through distributors. We recognize revenue in accordance with SEC Staff Accounting Bulletin No. 104, “Revenue Recognition,” which requires that four basic criteria must be met before revenue can be recognized: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred and title and the risks and rewards of ownership have been transferred to our customer or services have been rendered; (iii) the price is fixed or determinable; and (iv) collectibility is reasonably assured.

Through August 2003, the terms of our purchase orders for products sold domestically required payment in full before title was transferred. Accordingly, with all other criteria being met, we recognized revenue when payment was received. For products sold internationally through our direct sales force we recognized revenue when all other criteria was met and we completed installation, which was when the customer became obligated to pay. In August 2003, we modified the sales arrangements with our customers so that title transfers to the customer upon shipment for domestic sales, and there is an enforceable obligation to pay upon shipment for international direct sales. Beginning in August 2003, we have been recording revenue for domestic sales and international direct sales upon shipment. As a result, during 2003 we recorded $19.9 million in revenue before the modification to our sales arrangements and $21.8 million (restated) in revenue after the modification to our sales arrangements. We recognize revenue for products sold to our distributors internationally when the product is delivered. Revenue unaffected by the changes in our customer agreements with distributors was $7.2 million for the year ended December 31, 2003.

elements to the delivered elements. We determined that the sales of our Diode system include separate deliverables consisting of the product, disposables and training. For these sales, we apply the relative fair value method, which requires us to allocate the total arrangement consideration to the relative fair value of each element. Deferred revenue attributable to the undelivered elements, primarily training, installation and disposables, are included in deferred revenue when the product is shipped and are recognized when the related items are delivered or the service is performed.

The key judgment related to our revenue recognition relates to the collectibility of payment from the customer. We evaluate the customer’s credit worthiness prior to the shipment of the product. Based on our assessment of the credit information available to us, we may determine the credit risk is higher than normally acceptable, and we will either decline the purchase or defer the revenue until payment is reasonably assured.

Although all sales are final, we accept returns of products in certain, limited circumstances and record a provision for sales returns based on historical experience concurrent with the recognition of revenue. The sales returns allowance is recorded as a reduction of accounts receivable, revenue and cost of revenue.

We recognize revenue for royalties under licensing agreements for our patented technology when the product using our technology is sold. We estimate and recognize the amount earned based on historical performance and current knowledge about the business operations of our licensees. Our estimates have been consistent with amounts historically reported by the licensees.

Valuation of Accounts Receivable. We maintain an allowance for uncollectible accounts receivable to estimate the risk of extending credit to customers. We evaluate our allowance for doubtful accounts based upon our knowledge of customers and their compliance with credit terms. The evaluation process includes a review of customers’ accounts on a regular basis which incorporates input from sales, service and finance personnel. The review process evaluates all account balances with amounts outstanding 60 days and other specific amounts for which information obtained indicates that the balance may be uncollectible. The allowance for doubtful accounts is adjusted based on such evaluation, with a corresponding provision included in general and administrative expenses. Account balances are charged off against the allowance when we feel it is probable the receivable will not be recovered. We do not have any off-balance-sheet credit exposure related to our customers.

Valuation of Inventory. Inventory is valued at the lower of cost (determined using the first-in, first-out method) or market. We periodically evaluate the carrying value of inventory and maintain an allowance for excess and obsolete inventory to adjust the carrying value as necessary to the lower of cost or market. We evaluate quantities on hand, physical condition and technical functionality, as these characteristics may be impacted by anticipated customer demand for current products and new product introductions. Unfavorable changes in estimates of excess and obsolete inventory would result in an increase in cost of revenue and a decrease in gross profit.

Valuation of Long-Lived Assets. Property, plant and equipment, and certain intangibles with finite lives are amortized over their useful lives. Useful lives are based on our estimate of the period that the assets will generate revenue or otherwise productively support our business goals. We monitor events and changes in circumstances, which could indicate that the carrying balances of long-lived assets may exceed the undiscounted expected future cash flows from those assets. If such a condition were to exist, we will recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.

Valuation of Goodwill and Other Intangible Assets. Goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment annually or whenever events or changes in circumstances indicate that the asset might be impaired. We conducted our annual impairment analysis of our goodwill and trade names as of June 30, 2004 and concluded there had not been an impairment. During the fourth quarter of 2004, we changed our strategy to focus our sales efforts on high-end laser products such as the new Waterlase MD^™ product, which was first sold during the fourth quarter of 2004. This conclusion was due to the increased

competition for relatively low-priced laser devices. As a result, the actual sales of Diolase Plus^™ were below our original expectations and we expect this trend to continue. We estimated the fair value of the Diolase Plus trade name based on a relief from royalty approach using discounted cash flows from revised projected Diolase Plus revenue. The $747,000 excess of the carrying value over the asset’s estimated fair value has been recorded as a charge to operations in the fourth quarter of 2004.

Warranty Cost. Products sold directly to end users are covered by a warranty against defects in material and workmanship for a period of one year. Products sold internationally to distributors are covered by a warranty on parts for up to fourteen months. Estimated warranty expenses are recorded as an accrued liability, with a corresponding provision to cost of revenue. This estimate is recognized concurrent with the recognition of revenue. The accrual is based on our historical experience and our expectation of future conditions. An increase in warranty claims or in the costs associated with servicing those claims would result in an increase in the accrual and a decrease in gross profit.

Litigation and Other Contingencies. We regularly evaluate our exposure to threatened or pending litigation and other business contingencies. Because of the uncertainties related to the amount of loss from litigation and other business contingencies, the recording of losses relating to such exposures requires significant judgment about the potential range of outcomes. As additional information about current or future litigation or other contingencies becomes available, we will assess whether such information warrants the recording of expense relating to contingencies. To be recorded as expense, a loss contingency must be both probable and reasonably estimable. If a loss contingency is material but is not both probable and estimable, we will disclose the matter in the notes to the financial statements. During the year ended December 31, 2004, we recorded a $6.4 million charge to operations for a patent infringement legal settlement related to the lawsuit between us and Diodem.

Income Taxes. We estimate our actual current tax expense together with assessing any temporary differences resulting from the different treatment of certain items, such as the timing for recognizing revenue and expenses, for tax and financial reporting purposes. These differences may result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. We are required to assess the likelihood that our deferred tax assets, which include net operating loss carryforwards and temporary differences that are expected to be deductible in future years, will be recoverable from future taxable income or tax planning strategies. If we conclude that our deferred tax assets are more likely than not to be realized (a probability level of more than 50%), a valuation allowance is not recorded.

During the year ended December 31, 2004, we determined that it was more likely than not that our deferred tax assets, which consist primarily of net operating loss, or NOL, carryforwards, would not be realized. In this determination, we considered factors such as our earnings history, future projections and tax planning strategies. If sufficient evidence of our ability to generate sufficient future taxable income in certain jurisdictions becomes apparent, we may reduce our valuation allowance, resulting in income tax benefits in our statement of operations and in additional paid-in-capital. Management evaluates the potential realization of our deferred tax assets and assesses the need for releasing the valuation allowance periodically.

Net Revenue. Net revenue consists of sales of our laser systems, related disposables and accessories, service revenue, training revenue and royalty revenue. We have at various times experienced fluctuations in net revenue due to seasonality. In our experience, net revenue in the first quarter typically is lower than average, and net revenue in the fourth quarter typically is higher than average, due to the buying patterns of dental professionals. The fourth quarter of 2004 accounted for 32% of our net revenue for the year, whereas the first quarter of 2004 accounted for 24% of net revenue for the year. The third quarter accounted for 20% of our net revenue in 2004, whereas the second quarter accounted for 24% of our net revenue in 2004. During 2004, our third quarter was significantly impacted by two items. We believe that many customers delayed purchasing decisions pending the anticipated launching of our new Waterlase product, the Waterlase MD. In addition, some of our U.S. trade shows and seminars were impacted in the southeast by the region’s major hurricanes. Trade shows and seminars are a significant sales-generating process for us. Our historical seasonality pattern is a recurring trend that we expect to continue. Since many of our costs are fixed in the short term, if we have a shortfall in revenue resulting from a change in our historical seasonality pattern, or otherwise, we may be unable to reduce expenses quickly enough to avoid losses.

Many dentists finance their purchases through third-party leasing companies or banks. In these transactions, the dentist first enters into a purchase order with us. We then enter into a purchase order with the leasing company, which purchases the product from us, and the dentist enters into a lease agreement with the leasing company. We receive payment in full for the product by the leasing company, and we are not a party to the lease with the dentist. The dentist pays the leasing company or bank in installments, and we do not bear the credit risk

that the dentist might not make payments. The leasing companies and banks do not have recourse to us for a dentist’s failure to make payments, nor do we have any obligation to take back the product at the end of the lease. Approximately 32% of our net revenue in the first nine months of 2005, 28% of our net revenue in 2004, 34% of our net revenue in 2003, and 36% of our net revenue in 2002 were generated from dentists who financed their purchase through National Technology Leasing Corporation, an equipment leasing broker. We are regularly approached by leasing companies seeking to finance purchases of our products and do not believe the loss of National Technology Leasing or any other current financing source would materially harm our business.

Cost of Revenue. Cost of revenue is comprised of all costs to manufacture our products, including materials, labor and related overhead costs such as depreciation, warranty and service costs.

Other Income, Net. Other income consists of gain (loss) on sale of assets. The gain on sale of assets primarily related to the sale and leaseback of our manufacturing facility in San Clemente, California in March 2001. This sale resulted in a gain of $316,000 and is being recognized over the remaining term of the lease, which expires in 2006. Other income in 2004 and 2003 included the amortization of deferred gain offset by a gain (loss) on the sale of certain fixed assets.

Sales and Marketing Expense. Sales and marketing expenses consist of salaries and benefits, commissions, and other costs related to our direct sales force, advertising costs and expenses related to trade shows and seminars.

General and Administrative Expense. General and administrative expenses consist of salaries and benefits of administrative personnel as well as insurance, professional and regulatory fees, provisions for doubtful accounts, penalties and interest on amounts collected from customers but not timely remitted to the states, and subsequent gain for the amount of the liability relieved by the state.

Engineering and Development Expense. Engineering and development expenses consist of engineering personnel salaries and benefits, prototype supplies, contract services and consulting fees related to product development.

Patent Infringement Legal Settlement. In January 2005, we acquired the intellectual property portfolio of Diodem consisting of certain U.S. and international patents of which four were asserted against us, and settled the existing litigation between us and Diodem, for consideration of $3.0 million in cash, 361,664 shares of common stock, and a five-year warrant exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share. In addition, if certain criteria specified in the purchase agreement are satisfied on or before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. These escrowed shares had a fair market value of $500,000 at the time of the Binding Letter of Intent. The total consideration was estimated to have a value of $7.0 million, excluding the value of the shares held in escrow. As of December 31, 2004, we accrued $6.4 million for the settlement of the existing litigation. In January 2005, upon issuance of the consideration, we also recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents or certain other patents held by us are licensed to a third party.

Impairment of Intangible Asset. During 2004, we determined that our intangible assets associated with trade names were impaired based on circumstances that arose in the fourth quarter surrounding future expected sales of our Diolase product. The underlying factors contributing to our revised estimate included a reduced projected rate of sales growth for this product as a result of increased competition for relatively low-priced laser devices resulting in management’s decision to focus our sales efforts on high-end laser products such as the new Waterlase MD product launched in the fourth quarter of 2004. An expense of $747,000 was recorded related to this impairment.

Non-Operating Income (Loss). Non-operating income (loss) consists of interest income and expense, foreign currency transaction gains and losses and items not directly related to our operations. Interest income relates to interest earned on our cash balances and short-term investments, and interest expense relates to interest costs on our line of credit. We generate a substantial portion of our net revenue from the sale of products outside the United States. Our sales in Europe are denominated principally in Euros, and our sales in other international markets are denominated in dollars. As we do not engage in hedging transactions to offset foreign currency fluctuations, we are at risk for changes in the value of the dollar relative to the value of the Euro. An increase in the relative value of the dollar would lead to less income from sales denominated in Euros unless we increase prices, which may not be possible due to competitive conditions in Europe. Conversely, a decrease in the relative value of the dollar would lead to more income from sales denominated in Euros. Additionally, we are obligated to pay expenses relating to our German facility in Euros. Thus, we are also at risk for changes in the value of the dollar relative to the Euro with respect to our obligation to pay expenses relating to our operations in Germany. An increase in the value of the dollar relative to the Euro would reduce the expenses associated with the operations of our German facility, whereas a decrease in the relative value of the dollar would increase the cost associated with the operations of our German facility.

During the year ended December 31, 2003, we determined that it was more likely than not that our deferred tax assets, which consist primarily of NOL carryforwards, would be realized, resulting in an $11.9 million net deferred tax benefit. This deferred tax benefit does not include $2.2 million for stock option deduction benefits recorded as a credit to additional paid-in-capital. We considered factors such as our profitable operating history, three years of cumulative income and projections of continued profitability at that time in making this determination.

The utilization of NOL and credit carryforwards may be limited under the provisions of Internal Revenue Code Section 382 and similar state provisions. Section 382 of the Internal Revenue Code of 1986 generally imposes an annual limitation on the amount of NOL carryforwards that may be used to offset taxable income where a corporation has undergone significant changes in its stock ownership. In October 2003, we completed an analysis to determine the potential applicability of any annual limitations imposed by Section 382. Based on our analysis, we believe that, as of December 31, 2004, we have, for federal income tax purposes, approximately $39.0 million of NOL carryforwards. Of this amount, approximately $34.5 million is available to offset 2005 federal taxable income and the taxable income generated in future years. Additional NOL carryforwards will become available at the rate of approximately $1.0 million per year for the years 2005 through 2009. However, any future ownership changes qualifying under Section 382 may limit our ability to use remaining NOL carryforwards.

Three and nine months ended September 30, 2005 compared with three and nine months ended September 30, 2004

Net Revenue. Net revenue for the third quarter of 2005 decreased from $12.3 million to $11.7 million, or 5.3% less than the third quarter of 2004. Net revenue for the first nine months of 2005 increased $1.4 million or 3.5% compared with the same period in 2004. We have experienced a shift in our sales which was first observed in the second quarter of 2004 and has continued through the third quarter of 2005. We believe this shift primarily involves the makeup of our end customer, whereby we are in a transition from selling to “innovators” to a larger more sustainable “early adoptor” market segment. We believe this market segment typically is associated with a longer selling cycle. We believe the size of the potential market, our position within that market and the expected long-term quality and reliability of our product offerings are fundamentally unchanged; however, the change in the rate of growth has caused us to examine our sales and marketing strategies. In addition, we have experienced a decline in buying activity due to start-up issues and design changes associated with our Waterlase MD product, which we believe is causing some of our customers to defer their ultimate purchasing decision.

We incurred an operating loss of $5.2 million and $16.0 million for the three and nine months ended September 30, 2005, respectively, compared to an operating loss of $2.1 million and operating income of $149,000 for the same periods in 2004. Our cost of revenue has been impacted by higher production costs and design improvements of our Waterlase MD, costs as a result of recent quality issues and the cost of customer training. Our sales and marketing expense has increased due to higher salaries and sales commissions, convention and speaker fees, and general overhead costs. General and administrative expense increased due to the cost of audit fees for our 2004 year end audit and expenses associated with our Sarbanes-Oxley Section 404 compliance, headcount increases, with an offset to the total by a reduction of legal fees. Engineering and development expense included costs of $2.0 million in the first quarter of 2005 to purchase a license to use certain patent rights from Surgilight for technology related to the field of presbyopia and the related expenses of the transaction. This payment was recorded as research and development expense under the provisions of SFAS No. 2 as the technology is solely used for our research and development function and has no alternative future use to us.

We had a net loss of $5.2 million or $0.23 per diluted share for the third quarter of 2005 and a net loss of $16.3 million or $0.71 per diluted share for the nine months ended September 30, 2005. Net loss for the third quarter of 2004 was $1.1 million or $0.05 per diluted share for the three months ended September 30, 2004 and net income of $344,000 or $0.01 per diluted share for the nine months ended September 30, 2004.

Sales of lasers were slower in the third quarter of 2005 compared to the preceding first and second quarter of 2005. As previously mentioned, we believe that our net revenue for the third quarter of 2005, as well as the second quarter of 2005, has been impacted by delayed purchasing decisions associated with design changes of our Waterlase MD. We believe this purchasing pattern may also impact our fourth quarter of 2005.

Domestic sales comprised approximately 72% of total sales for both the three and nine months ended September 30, 2005 compared to approximately 74% and 73% of total sales for the same periods in 2004, respectively. The lower percentage total for the third quarter of 2005 is associated with the aforementioned Waterlase MD design changes and deferred purchasing decisions of our customers. We believe this buying trend may continue through the fourth quarter of 2005.

Sales of our Waterlase system accounted for approximately 78% and 83% of net revenue for the three and nine months ended September 30, 2005, respectively, compared to approximately 80% and 81% for the same periods of 2004. For the year ended December 31, 2004, Waterlase system sales were 84% of net revenue. We expect that our Waterlase system will account for approximately 80% to 85% of net revenue for 2005.

Significant estimates affecting sales include the reserve for sales returns. The reserve is based on historical experience from 1998 through the present. Our overall historical trend stayed consistent for the third quarter of 2005. Our reserve for sales returns resulted in a net decrease of $62,000, from $420,000 at December 31, 2004 to $358,000 at September 30, 2005.

Gross Profit. Gross margin decreased from 58.0% to 45.5% from the third quarter of 2004 compared to the third quarter of 2005 as a result of higher production costs, costs of redesign of the Waterlase MD related to quality improvements, and the costs of customer training associated with our multiple element arrangements, which are classified as cost of revenue. Training negatively impacted gross margins for the three and nine months ended September 30, 2005 by 2% and 3%, respectively, compared to the impact on gross margins for the three and nine months ended September 30, 2004, of 3% and 3%, respectively. We believe that our gross margin will continue to be impacted until our Waterlase MD reaches a mature state of production, which will impact the full fiscal year of 2005. We expect that increased manufacturing costs associated with the Waterlase MD will continue until our factory has achieved a proper balance between all products and throughput efficiency is maximized. In addition, as compared to the three and nine months ended September 30, 2004, we have increased our fixed costs of manufacturing with the addition of a new facility in May 2004 and higher labor costs for quality control, materials management and other support activities. During the first nine months of 2005, we increased our reserve for excess and obsolete inventory by $694,000 related to unusable raw materials resulting from design changes to the Waterlase MD.

Sales and Marketing Expense. Sales and marketing expense for the three and nine months ended September 30, 2005 increased $345,000 and $1.8 million, respectively, compared to the comparable prior year periods. As a percentage of net revenue, sales and marketing expense increased from 46.4% for the three months ended September 30, 2004 to 52.0% for the three months ended September 30, 2005. While some of our sales and marketing costs are fixed, most are discretionary expenditures aimed at furthering our market penetration and positioning us for sustained long-term growth. We did not reduce our discretionary expenditure level in the third quarter or first nine months of the fiscal year 2005. The increase in absolute dollars for the third quarter of 2005 compared to the third quarter of 2004 is primarily related to increases in salaries and wages of $256,000, increases in conventions and seminars of $149,000 and increases in overall infrastructure support of $871,000, offset by decreases totaling $931,000 for advertising and promotions and international operations. The increase in absolute dollars for the nine months of 2005 compared to the nine months of 2004 is primarily related to increases of $416,000 for higher salaries and commissions, $878,000 for conventions and seminars, $369,000 for overall infrastructure support, and $92,000 for our international operations. During the first quarter and continuing into the second quarter of 2005, we realigned our domestic sales force affecting sales representative commission and territory configurations. As part of this planned process, we experienced some involuntary and voluntary attrition in the sales force. While we believe that the effects of these changes will allow us to better service our customers, especially those in the “early adoptor” market segment, there continues to be an impact on product sales as the newly configured sales force ramps up to a full state of productivity resulting in lower sales volume for the three months ended September 30, 2005. As of September 30, 2005, we had 35 direct sales staff in North America and 7 direct sales staff covering Europe. We expect our sales and marketing expense to continue to increase in the fourth quarter of 2005, in large part due to increases in costs associated with education and training of potential customers which is an essential component of our effort to increase market acceptance of laser technology and our products. We expect sales and marketing expense to decrease as a percentage of revenue in the fourth quarter of 2005.

General and Administrative Expense. General and administrative expense was $3.3 million in the third quarter of 2005, compared to $2.5 million for the third quarter of 2004, representing an absolute dollar increase of $707,000 and an increase from 20.6% of net revenue for the third quarter of 2004 to 27.9% of net revenue for the third quarter of 2005. For the nine months ended September 30, 2005 general and administrative expense increased $7.5 million compared to the nine months of 2004. The most significant portions of this increase for the third quarter related to increased professional fees of $377,000 associated with the audit of 2004 and the restated financial statements (an increase of $3.1 million comparing the first nine months of 2005 to the comparable period of 2004). Other personnel and administrative costs increased approximately $622,000 and $2.7 million for the three and nine months ended September 30, 2005, respectively, as compared to the comparable periods of 2004, representing increased infrastructure in finance, information technology, human resources and administration, in response to meeting the ongoing compliance standards related to the Sarbanes-Oxley Act. The costs related to compliance with the Sarbanes-Oxley Act, which included professional fees as

well as temporary labor, increased $132,000 when comparing the three months ended September 30, 2005 to the three months ended September 30, 2004, however the increase for the first nine months of 2005 to the comparable period of 2004 was $1.7 million. The total increase in expense for the three months ended September 30, 2005 was offset by a decrease in legal fees of $424,000 primarily associated with the settlement of the lawsuit with Diodem. The increase in our general and administrative expense for the nine months ended September 30, 2005 was offset by a gain in the amount of $99,000 on the abatement of penalties and interest on sales tax during the period. We expect general and administrative expense of the third quarter of 2005 to stay relatively constant in the fourth quarter of 2005.

Engineering and Development Expense. Engineering and development expense for the three and nine months ended September 30, 2005 was $1.2 million and $5.3 million, respectively, representing an increase of $151,000 and $2.8 million, respectively, compared to the same periods of 2004. As a percentage of net revenue, engineering and development expense increased from 8.5% for the third quarter of 2004 to 10.3% for the third quarter of 2005, and from 6.1% for the first nine months of 2004 to 12.3% for the first nine months of 2005. The increase in the third quarter of 2005 is due primarily to higher employee costs and patent fees and overall infrastructure support costs attributable to engineering and development, offset by special project costs incurred in the prior year. The increase in the nine month period is primarily the result of our acquiring a license to use certain patent rights totaling $2.0 million from Surgilight in the field of presbyopia and the related expenses of the transaction. We did not acquire the underlying patents, nor was there a business combination in connection therewith. Under the terms of the agreement, we will pay an additional $200,000 in total to Surgilight commencing in 2006 through 2010. The entire consideration, including the transaction costs, has been expensed as in-process research and development. The remaining $200,000 will be expensed as incurred, in accordance with FAS No. 2, “Accounting for Research and Development Costs.” During the third quarter of 2005, we filed with the FDA for market approval to use our laser technology in the field of ophthalmology and oculoplasty. Our filing with the FDA requested marketing clearance for the OCULASE MD™ laser designed to perform various indications for general tissue ablation, anterior capsulotomy (secondary cataract removal), skin resurfacing, and treatment of wrinkles of tissue surrounding the eye and orbit. We believe that this filing represents a significant milestone for our research and development efforts in new fields of medical use for our lasers. We expect to modestly increase our spending in product development during the remainder of 2005, excluding the cost of this license during the first quarter of 2005.

Year Ended December 31, 2004 Compared With Year Ended December 31, 2003 (Restated)

Net Revenue. Revenue for the year ended December 31, 2004 was $60.7 million, an increase of $11.9 million, or 24%, as compared with revenue of $48.8 million for the year ended December 31, 2003. The increase of $11.9 million consists of increases in the number of products and services sold as a result of a greater marketing and sales focus. However, the rate of increase in revenue growth year over year represents a decrease from the recent historical trend. This decrease in the historical rate of growth was first observed in the second quarter of 2004 and has continued through the fourth quarter of 2004. While we have identified during the year a number of factors that could have influenced the change in the rate of growth, at this point in time we believe that the change is not an aberration but rather a shift in our growth rate. We believe this shift involves the makeup of our end customer, whereby we are in a transition from selling to “innovators” to a larger more sustainable “early adapter” market segment. This market segment is typically associated with a longer selling cycle. The size of the potential market, our position within that market and the quality and reliability of our product offerings are fundamentally unchanged; however, the change in the rate of growth has caused us to examine our sales and marketing strategies. Although we do not expect our revenue growth to reach previous historical rates that were in excess of 50%, we do expect modest revenue growth in 2005.

The results for 2003 were favorably impacted due to a change in the timing of revenue recognition. In August 2003, we modified our sales arrangements with our customers and began recognizing revenue upon shipment for our domestic sales, or on an accrual basis, which had previously been recognized upon receipt of payment in full, or on a cash basis. Additionally, we began to recognize revenue upon shipment for our international direct sales, which had previously been recognized after completion of installation. As a result,

during 2003 we recorded $19.9 million in net revenue under the revenue recognition policy in effect before the modification to our sales arrangements and $21.8 million in net revenue under our revenue recognition policy in effect after the modification to our sales arrangements. Net revenues unaffected by the changes in our revenue recognition policy were $7.2 million for the year ended December 31, 2003.

Our Waterlase system comprised 84% and 83% of our net revenue for the years ended December 31, 2004 and 2003, respectively. Our Diolase system comprised 11% and 12% of our revenue for the years ended December 31, 2004 and 2003, respectively. We expect the Waterlase system will continue to account for the majority of our sales.

Many dentists finance their purchases through third party leasing companies. Approximately 28% of our net revenue for the year ended December 31, 2004 and 34% of our net revenue for the year ended December 31, 2003 were generated from dentists who financed their purchases through National Technology Leasing Corporation, an independent equipment leasing company. The recent history of low interest rates over the past several years may have benefited purchasers of our products by reducing the interest expense to finance the purchase or lease of our products, although we do not believe it is possible to measure the effect of lower interest rates on our sales.

International revenue for the year ended December 31, 2004 was $11.5 million, or 19% of net revenue, as compared with $9.8 million, or 20% of net revenue, for the year ended December 31, 2003. Sales to Asia, Latin America, Pacific Rim countries and Australia were approximately $4.9 million while sales to Europe, Middle East and Africa (EMEA) were approximately $6.6 million for the year ended December 31, 2004 compared to $4.5 million and $5.3 million, respectively, for the year ended December 31, 2003. We expected our international revenue to remain at approximately 20% of our net revenue for 2005.

Gross Profit. Gross profit for the year ended December 31, 2004 was $36.0 million, or 59% of net revenue, an increase of $4.7 million, as compared with gross profit of $31.3 million, or 64% of net revenue for the year ended December 31, 2003. Gross profit for the year ended December 31, 2003 included $12.3 million of gross profit for domestic sales recognized on a cash basis and $13.4 million recognized on an accrual basis. Gross profit for the year ended December 31, 2003 included $1.1 million recognized for international direct sales upon completion of installation and $1.1 million recognized upon shipment. The decrease in gross profit as a percentage of revenue was due to an increase in manufacturing costs related to the launch of the new Waterlase MD product in the fourth quarter of 2004 as well to an increase in fixed manufacturing infrastructure, including quality control, materials management and other support activities. We are generating a lower gross margin on the initial production quantities of the Waterlase MD due to these factors. We expect that increased manufacturing costs associated with the new Waterlase MD will continue until our factory has achieved a proper balance between all products and throughput efficiency is maximized. We also experienced an increase in excess and obsolete inventory of $441,000 associated with slow-moving raw materials, which decreased our gross margin approximately 1%. Additionally, included in cost of revenue is $1.9 million and $0 of expenses for the years ended December 31, 2004 and 2003, respectively, for training and WCLI seminars related to our multiple element arrangements, which decreased our gross margin by approximately 2%. Once maximization of efficiency is achieved, we expect that our gross margins will stabilize in the low to mid 60% range.

Other Income, Net. Other income consists of gain on sale of assets. The gain on sale of assets for the years ended December 31, 2004 and 2003 of $63,000 each year related to the sale and leaseback of our manufacturing facility in San Clemente, California in March 2001. This sale resulted in a gain of $316,000 and is being recognized over the remaining term of the lease, which expires in 2006. Other income in 2004 included the amortization of deferred gain of $63,000 offset by a loss of $31,000 on the sale of certain fixed assets. Other income in 2003 included the amortization of deferred gain of $63,000 plus a gain of $13,000 on the sale of certain fixed assets.

Operating Expenses. Operating expenses for the year ended December 31, 2004 were $45.4 million, or 75% of net revenue, a $21.0 million increase as compared with $24.4 million, or 50% of net revenue for the year

ended December 31, 2003. The increases in operating expenses were, for the most part, related to planned marketing expenses geared to an expected higher level of sales and general and administrative expenses driven mainly by high levels of legal and compliance costs as described below. Other increases in operating expenses represent increases in fixed organizational infrastructure costs necessary to support our growth. We expect to be able to leverage the fixed nature of these costs as our revenue increases.

Sales and Marketing Expense. Sales and marketing expenses for the year ended December 31, 2004 were $23.1 million, or 38% of net revenue, as compared with $16.8 million, or 34% of net revenue, for the year ended December 31, 2003. Approximately $3.7 million of the increase was due to personnel related costs, including commission expense on higher sales, increase in our sales force and related travel and support costs. Marketing expense, including advertising, direct mailing fees, trade shows and seminars increased approximately $2.6 million, of which approximately half related to the launch of our new Waterlase MD product. We expect our sales and marketing expenses to continue to increase, in large part due to increases in expenses associated with education and training of potential customers which is an essential component of our effort to increase market acceptance of laser technology and our products. We expect sales and marketing expense to remain relatively consistent as a percentage of net revenue in 2005.

General and Administrative Expense. General and administrative expenses for the year ended December 31, 2004 were $11.5 million, or 19% of net revenue, as compared with $5.1 million, or 10% of net revenue, for the year ended December 31, 2003. Legal fees, related principally to the Diodem litigation, totaled $4.3 million, an increase of $3.4 million from the prior year. Costs related to compliance with the Sarbanes-Oxley Act, including professional expenses as well as temporary labor, were approximately $1.3 million, the majority of which were expended in the last six months of 2004. Other personnel and related costs increased approximately $848,000, representing increased infrastructure in finance, information technology, human resources and administration both in response to our growth as well as to meet the ongoing compliance standards related to the Sarbanes-Oxley Act. We expect professional fee expense to continue in response to maintenance and improvements of internal controls under the Sarbanes-Oxley Act, albeit at a lesser amount than 2004. Additionally, our general and administrative expense for the year ended December 31, 2004, included amounts accrued for sales tax liability and related penalties and interest totaling $269,000 compared to $375,000 for the same period of 2003. In 2004, we also recognized a gain of $372,000 for the abatement of certain penalties and interest related to the sales tax compared to $17,000 for the same period of 2003. Costs associated with general liability insurance, employee group insurance and workers compensation insurance increased by approximately $618,000 in 2004 as compared to 2003. We expect these insurance costs to continue to increase significantly as a function of our growth and insurance market conditions in general. We recorded a reserve for uncollectible accounts totaling $354,000 in 2004, an increase of $106,000 compared to 2003. Bank charges relating to credit card sales increased by $124,000 as compared to 2003 and will likely continue to grow commensurate with our sales growth. Overall, general and administrative costs are expected to decrease as a percentage of revenue primarily through reduced legal related expenses as a result of the conclusion of our patent litigation with Diodem.

Engineering and Development Expense. Engineering and development expenses for the year ended December 31, 2004 were $3.6 million, or 6% of net revenue, as compared with $2.5 million, or 5% of net revenue, for the year ended December 31, 2003. Approximately half of the increase in absolute dollars is due to materials and consulting fees related to the development of the Waterlase MD product, with the balance resulting from an increase in the level of research projects and patent development. We expect engineering and development expenses to increase during 2005 as we develop new applications for our technology and expand on the usage of recently acquired patents.

Patent Infringement Legal Settlement. In January 2005, we acquired the intellectual property portfolio of Diodem, consisting of certain U.S. and international patents of which four were asserted against us, and settled the existing litigation between us and Diodem, for consideration of $3.0 million in cash, 361,664 shares of common stock, and a five-year warrant exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share. In addition, if certain criteria specified in the purchase agreement are satisfied on or before July

2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. These escrowed shares had a fair market value of $500,000 at the time of the Binding Letter of Intent. The total consideration was estimated to have a value of $7.0 million, excluding the value of the shares held in escrow. As of December 31, 2004, we accrued $6.4 million for the settlement of the existing litigation. In January 2005, we recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents or certain other patents held by us are licensed to a third party.

Impairment of Intangible Asset. During 2004, we determined that our intangible assets associated with certain trade names were impaired based on circumstances that arose in the fourth quarter surrounding future expected sales of our Diolase product. The underlying factors contributing to our revised estimate included a reduced projected rate of sales growth for this product as a result of increased competition for relatively low-priced laser devices resulting in management’s decision to focus our sales efforts on high-end laser products such as the new Waterlase MD product launched in the fourth quarter of 2004. An expense of $747,000 was recorded related to this impairment.

Non-Operating Income (Loss)

Gain on Foreign Currency Transactions. We realized an $86,000 gain on foreign currency transactions for the year ended December 31, 2004, compared to $232,000 for the year ended December 31, 2003 due to the changes in exchange rates between the United States dollar and Euro. Due to the relatively low volume of transactions denominated in currencies other than the U.S. dollar, we have not engaged in hedging transactions to offset foreign currency fluctuations. Therefore, we are at risk for changes in the value of the dollar relative to the value of the Euro, which is the only non-U.S. dollar denominated currency in which we have transacted business.

Gain on Sale of Marketable Securities. Our investments are comprised of U.S. government securities and have been classified as available-for-sale. We realized a $91,000 gain on sale of marketable securities for the year ended December 31, 2004, compared to $0 for the year ended December 31, 2003. As a result of the $41.9 million in net proceeds received from our public offering in the first quarter of 2004, we engaged in investment transactions throughout 2004.

Interest Income. Interest income relates to interest earned on our cash and investment balances. Interest income for the year ended December 31, 2004 was $470,000 as compared with $27,000 for the year ended December 31, 2003 due to an increase in our investment balances resulting from our public offering in the first quarter of 2004.

Interest Expense. Interest expense for the year ended December 31, 2004 was $88,000 as compared to $55,000 for the year ended December 31, 2003. Interest expense in 2004 consisted of interest on our outstanding balance on our line of credit, standby fees relating to our increased borrowing capacity under the line of credit, and the periodic use of the line during the year.

Income Taxes. An income tax provision of $14.4 million was recognized for the year ended December 31, 2004. A significant component of this income tax provision was the recording of the $21.1 million valuation allowance against our deferred tax assets. For the year ended December 31, 2003, we recognized an income tax benefit of $11.9 million and a credit of $2.2 million to additional paid-in capital. The income tax benefit for the year ended December 31, 2003 was due to the reduction of the valuation allowance in the amount of $16.2 million. The credit to additional paid in capital was the result of a stock option deduction available to us in 2003 and prior year deductions included in the deferred tax assets which were previously offset by the valuation allowance. In assessing the realizability of deferred tax assets, management considers whether it is more likely

than not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the projected future taxable income and tax planning strategies in making this assessment. Based upon our operating losses and the weight of the available evidence, management believes it is more likely than not that we will not realize all of these deductible differences. As of December 31, 2004, we had net operating loss carryforwards for federal and state purposes of approximately $39.0 million and $11.3 million, respectively, which will begin expiring in 2005. As of December 31, 2004, we had research and development credit carryforwards for federal and state purposes of approximately $558,000 and $250,000, respectively, which will begin expiring in 2011 for federal purposes and carryforward indefinitely for state purposes. The utilization of net operating loss and credit carryforwards may be limited under the provisions of Internal Revenue Code Section 382 and similar state provisions.

Year Ended December 31, 2003 (Restated) Compared With Year Ended December 31, 2002 (Restated)

Net Revenue. Net revenue for the year ended December 31, 2003 was $48.8 million, an increase of $21.5 million, or 79%, as compared with net revenue of $27.3 million for the year ended December 31, 2002. Approximately $16.2 million of the increase resulted from a 59% increase in sales of products and services and the balance was due to a change in the timing of revenue recognition described below.

In August 2003, we modified our sales arrangements with our customers and began recognizing revenue upon shipment for our domestic sales, or on an accrual basis, which had previously been recognized upon receipt of payment in full, or on a cash basis. Additionally, we began to recognize revenue upon shipment for our international direct sales, which had previously been recognized after completion of installation. As a result of the change in our revenue recognition policy during the third quarter of 2003, our net revenue is not directly comparable to the year ended December 31, 2002. During the year ended December 31, 2002 domestic sales were recognized on a cash basis and international direct sales were recognized after completion of installation.

Revenue during the year ended December 31, 2003 included $18.3 million of net revenue for domestic sales recognized on a cash basis and $20.1 million recognized on an accrual basis. Revenue during the year ended December 31, 2003 included $1.6 million recognized for international direct sales upon completion of installation and $1.7 million recognized upon shipment. As of December 31, 2003 our balance sheet reflects approximately $144,000 that has been deferred on product shipments for which payment has not been received in full for domestic sales and where installation has not been completed for international direct sales. We cannot provide any assurance as to the timing or whether the deferred revenue will ultimately be collected, or

when or whether installations will be completed. Other than the possible recognition of this deferred revenue balance, the positive impact to revenue for the year ended December 31, 2003 that resulted from the change in our revenue recognition policy will not occur in future periods.

The Waterlase and LaserSmile^™ systems accounted for approximately 83% and 12% of our net revenue for the year ended December 31, 2003, respectively.

Many dentists finance their purchases through third party leasing companies. Approximately 34% of our net revenue for the year ended December 31, 2003 and 36% of our revenue for the year ended December 31, 2002 were generated from dentists who financed their purchases through National Technology Leasing Corporation, an independent equipment leasing company. The decline in interest rates between 2003 and 2002 may have benefited purchasers of our products by reducing the interest expense to finance the purchase or lease of our products, although we do not believe it is possible to measure the effect of lower interest rates on our sales.

International net revenue for the year ended December 31, 2003 was $9.8 million, or 20% of net revenue, as compared with $6.2 million, or 23% of net revenue, for the year ended December 31, 2002. Revenue to Asia and Europe was $4.5 million and $5.3 million, respectively, for the year ended December 31, 2003 compared to $3.3 million and $2.9 million, respectively, for the year ended December 31, 2002. We had expected international

net revenue to grow as a percentage of net revenue in 2003 and in the future. Although international net revenue grew 58% year over year, in line with our overall expectations for net revenue, domestic revenue growth was stronger due to higher than expected demand in the United States. During 2003, we invested more resources in international sales and marketing and related infrastructure.

Gross Profit. Gross profit for the year ended December 31, 2003 was $31.3 million, or 64% of net revenue, an increase of $14.4 million, as compared with gross profit of $16.9 million, or 62% of net revenue for the year ended December 31, 2002. Gross profit for the year ended December 31, 2003 included $12.3 million of gross profit for domestic net revenue recognized on a cash basis and $13.4 million recognized on an accrual basis. Gross profit for the year ended December 31, 2003 included $1.1 million recognized for international direct revenue upon completion of installation and $1.1 million recognized upon shipment. The increase in gross profit is attributable to leveraging the increase in net revenue against fixed and partially fixed manufacturing costs, reflecting better absorption of fixed manufacturing costs. The increase is also due to the relative increase in domestic revenue as a percentage of total revenue, which generated higher gross margins. The gross margin associated with net revenue to international distributors is generally lower as the selling price is lower in order to compensate dealers for the marketing and sales costs they must incur. International net revenue increased as a percentage of total revenue from 2001 to 2002 but then decreased as a percentage in 2003. Therefore, while gross margin may continue to increase due to manufacturing efficiencies, relative increases in international revenue compared to domestic revenue may offset the effect of manufacturing efficiencies on gross profit. Revenue of the Diolase and Pulsemaster^® systems did not have a significant impact on gross profit.

Other Income, Net. Other income consists of gain on sale of assets. The gain on sale of assets for the years ended December 31, 2003 and 2002 of $63,000 each year related to the sale and leaseback of our manufacturing facility in San Clemente, California in March 2001. This sale resulted in a gain of $316,000 and is being recognized over the remaining term of the lease, which expires in 2006. Other income in 2003 included the amortization of deferred gain of $63,000 plus a gain of $13,000 on the sale of certain other assets.

Operating Expenses. Operating expenses for the year ended December 31, 2003 were $24.4 million, or 50% of revenue as compared with $16.0 million, or 58% of revenue for the year ended December 31, 2002. Approximately 72% of the increase, or $6.1 million, consists of sales and marketing costs incurred to generate the increase in revenue.

Sales and Marketing Expense. Sales and marketing expenses for the year ended December 31, 2003 were $16.8 million, or 34% of net revenue, as compared with $10.7 million, or 39% of net revenue, for the year ended December 31, 2002. Approximately 40% of the increase in absolute dollars was due to the increase in our direct sales force, development of our infrastructure for international sales, and higher commission expense related to the increase in sales, including recognition, of approximately $334,000 in deferred commission expense related to revenue recognized that had been deferred. Marketing expense increased $1.4 million due to increased staff and additional direct marketing activities in Europe. Expenses related to trade shows, seminars and the World Clinical Laser Institute increased approximately $1.0 million due to an expansion in the scope of activities related to those programs. We expect our sales and marketing expenses to continue to increase, in large part due to increases in expenses associated with education and training of potential customers, which is an essential component of our effort to increase market acceptance of laser technology and our products. Overall, sales and marketing expense is expected to decrease slightly as a percentage of revenue, assuming sales continue to grow in line with our expectations. Incremental costs relating to the marketing and sale of the American Dental Laser products have not had and are not expected to have a significant impact on total sales and marketing expense.

General and Administrative Expense. General and administrative expenses for the year ended December 31, 2003 were $5.1 million, or 10% of net revenue, as compared with $3.6 million, or 13% of net revenue, for the year ended December 31, 2002. Professional expenses accounted for approximately 50% of the dollar increase, including approximately $450,000 in expenses related to the restatement of our consolidated financial statements, fees related to legal proceedings and fees incurred on various consulting projects. We expect professional fee

expense to continue to increase as a cost of compliance with new regulatory requirements, such as those generated from the Sarbanes-Oxley Act. Costs associated with general liability coverage, employee group insurance and workers compensation insurance increased by $465,000 in 2003 as compared to 2002. We expect these insurance costs to continue to increase significantly as a function of our growth and insurance market conditions in general. Bank charges relating to credit card sales increased by $140,000 as compared to 2002 and will likely continue to grow commensurate with our sales growth. No significant additional general and administrative expenses have been incurred or are expected from the acquisition and production of the American Dental Laser products except for amortization expense related to certain intangible assets acquired.

Engineering and Development Expense. Engineering and development expenses for the year ended December 31, 2003 were $2.5 million, or 5% of net revenue, as compared with $1.7 million, or 6% of net revenue, for the year ended December 31, 2002. The increase in absolute dollars was due to materials and consulting fees related to product development and enhancement. The change in engineering and development expenses as a percentage of revenue reflects the larger sales base and normal fluctuations in the scope of current research and development projects.

Non-Operating Income (Loss)

Gain on Foreign Currency Transactions. We realized a $232,000 gain on foreign currency transactions for the year ended December 31 2003, compared to $51,000 for the year ended December 31, 2002 due to the changes in exchange rates between the United States dollar and Euro.

Gain on Forward Exchange Contracts. In the years ended December 31, 2003 and 2002, we realized gains of $22,000 and $152,000, respectively, due to the increase in the fair market value of our forward exchange contracts which we purchased in connection with the debt incurred to acquire our facility in Germany. On February 3, 2003, the contracts expired and were not renewed.

Interest Income. Interest income relates to interest earned on our cash balances. Interest income for the year ended December 31, 2003 was $27,000 as compared with $18,000 for the year ended December 31, 2002 due to an increase in our cash balance.

Interest Expense. Interest expense decreased $80,000, or 59%, to $55,000 for the year ended December 31, 2003, as compared with the year ended December 31, 2002 due to a decrease in the effective interest rate on our credit facility. In May 2003, we entered into a $5.0 million credit facility with a bank to replace our existing line of credit. The new line of credit bears interest at LIBOR plus 2.25% as compared with the previous line of LIBOR plus 0.5%. Although the nominal rate on the new facility is higher, the previous facility was burdened by the amortization of the cost of a third-party guaranty.

Income Taxes. An income tax benefit of $11.9 million and a credit of $2.2 million to additional paid in capital was recognized for the year ended December 31, 2003. This was primarily due to the reduction of the valuation allowance in the amount of $16.2 million. The credit to additional paid-in-capital was the result of a stock option deduction available to use in the current year and prior year deductions included in the deferred tax assets which were previously offset by the valuation allowance. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and the projection for future taxable income over the periods when the deferred tax assets are deductible, management believes it is more likely than not that we will realize all of these deductible differences. As of December 31, 2003, we had net operating loss carryforwards for federal and state purposes of approximately $32.4 million and $7.4 million, respectively, which will begin expiring in 2004. As of December 31, 2003, we had research and development credit carryforwards for federal and state purposes of approximately $437,000 and $54,000, respectively, which will begin expiring in 2011 for federal purposes and

carryforward indefinitely for state purposes. The utilization of net operating loss and credit carryforwards may be limited under the provisions of Internal Revenue Code Section 382 and similar state provisions.

Liquidity and Capital Resources

September 30, 2005

At September 30, 2005, we had approximately $14.2 million in net working capital, a decrease of $15.8 million from $30.0 million at December 31, 2004. During the first nine months of 2005 we paid the $3.0 million cash portion of our obligation under the legal settlement with Diodem, $2.0 million to Surgilight, related to our acquiring a license to use certain patent rights related to the field of presbyopia, and we used approximately $13.1 million in operations, net of the payments for Diodem and Surgilight. For the nine months ended September 30, 2005, our sources of cash were net borrowings on our line of credit of $5.0 million and a net $1.2 million from the exercise of stock options, offset by the use of funds in the amount of $689,000 for the payment of dividends. Our principal source of liquidity at September 30, 2005 consisted of our cash, cash equivalents, and short-term investments (see discussion below regarding the restriction that became effective in November 2005).

Accounts receivable decreased 35% or $3.4 million from the end of the fourth quarter of 2004 to the end of the third quarter of 2005 primarily due to lower sales volume in the third quarter of 2005. Days sales outstanding (DSO) in accounts receivable were 54 days when measured at September 30, 2005. Net inventory increased 29% or $2.3 million from the end of the fourth quarter of 2004 to the end of the third quarter of 2005. Inventory turnover equals 2.4 turns per year when measured at September 30, 2005.

During the quarter ended March 31, 2005, we issued 361,664 shares of our common stock (valued at approximately $3.5 million) and a five-year warrant (valued at approximately $443,000) exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share, in addition to the $3.0 million cash payment, for the legal settlement with Diodem. In addition, if certain criteria specified in the agreement are satisfied before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. The common stock issued, the escrow shares and the warrant shares have certain registration rights. The total consideration was estimated to have a value of approximately $7.0 million, excluding the value of the shares held in escrow which are contingent in nature, but including the value of the patents acquired in January 2005. As of December 31, 2004, we accrued approximately $6.4 million for the settlement of the existing litigation. In January 2005, we recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents held by us are licensed to a third party. In order to secure performance by us of these financial obligations, the parties entered into an intellectual property security agreement, pursuant to which, subject to the rights of existing creditors and the rights of any future creditors to the extent provided in the agreement, we granted Diodem a security interest in all of their right, title and interest in the royalty patents. In addition, we will be required, by January, 2006, to provide Diodem a ten-year letter of credit from a bank in the amount of $500,000 as additional security.

At September 30, 2005, we had a $10.0 million credit facility with a bank. On September 19, 2005, we entered into a third amendment to our credit facility with the bank which extended the term from September 30, 2005 to September 30, 2006. In addition, certain material covenants of the credit facility were modified to decrease the required minimum tangible net worth from $30.0 million to $24.0 million, decrease the required minimum balance of cash (including investments in U.S. Treasuries) from $20.0 million to $12.0 million, and amend the quarterly profitability condition commencing with the fiscal quarter ended March 31, 2006. At September 30, 2005, $5.0 million was borrowed on the credit facility. Borrowings under the facility bear interest

at LIBOR plus 2.25% for minimum borrowing amounts of $500,000 and with two business days notice or at a variable rate equivalent to prime rate for amounts below $500,000 or with less than two business days notice and are payable on demand upon expiration of the facility. All borrowings during the first nine months of 2005 were at prime rate. We granted the bank a security interest in and to all of our equipment, inventory, accounts receivable and other assets. As of September 30, 2005, we were non-compliant with our covenants relating to minimum tangible net worth and debt to tangible net worth for which we received a waiver in November 2005.

In November 2005, we also entered into a fourth amendment to our credit facility with the bank which eliminates all of our financial covenants, including the minimum cash balance of $12.0 million. Under the new amendment, we agreed to collateralize the facility with our short-term investment in U.S. Treasury debt securities which had a fair market value of $9.9 million as of September 30, 2005, which is shown as short-term investment, restricted on our consolidated balance sheets.

We had no material commitments for capital expenditures as of September 30, 2005 and have not entered into any material commitments after that date.

The following table presents our expected cash requirements for contractual obligations outstanding as of September 30, 2005, the three months ending December 31, 2005, and for the years ending December 31, thereafter:


	Outstanding at September 30, 2005		Three Months Ending December 31, 2005		Years Ending December 31,
	Outstanding at September 30, 2005		Three Months Ending December 31, 2005		2006		2007		2008		2009		2010
Operating leases and commitments	$	661,000	$	180,000	$	334,000	$	66,000	$	31,000	$	25,000	$	25,000

We believe that our current cash balances and investments, coupled with cash generated from our expected increases in revenue, expected margin enhancements associated with improving quality, and an expected decrease in expenses when measured to the first nine months of 2005, will provide adequate liquidity to meet our capital requirements and sustain our operations for at least the next twelve months. There can be no assurances of these improvements; therefore, our future capital requirements may depend on many factors, including the extent and timing of the rate at which our business grows and other improvements occur. We may be required to seek additional funding through either debt financing, or public or private equity, or a combination of funding methods to meet our capital requirements and sustain our operations. However, additional funds may not be available on terms acceptable to us or at all.

December 31, 2004

At December 31, 2004, we had $30.0 million in net working capital, an increase of $19.9 million from $10.1 million (restated) at December 31, 2003. Our principal source of liquidity at December 31, 2004 consisted of our cash balance of $6.1 million and investments in marketable securities of $25.3 million. For the year ended December 31, 2004, our sources of cash were net proceeds of $41.9 million from our public offering and $1.3 million from the exercise of stock options. Principal uses of cash for the year ended December 31, 2004 were investments in marketable securities of $25.2 million, funds used to repurchase common stock of $16.4 million, payments totaling approximately $2.7 million to pay off debt outstanding at December 31, 2003, additions to long term assets of approximately $1.4 million and dividends paid of $689,000. Cash used in operating activities was $1.6 million for the year ended December 31, 2004. The net effect on cash of operating, investing, and financing activities for the year ended December 31, 2004 was a decrease of $5.0 million. Cash and cash equivalents and short-term investments increased $20.4 million from December 31, 2003 to December 31, 2004.

Principal among the changes in assets and liabilities which used cash were increases in accounts receivable and inventory. Net accounts receivable at December 31, 2004 increased approximately $3.9 million from

December 31, 2003. The increase is primarily attributable to the increase in the sales volume experienced in 2004. Specifically, our revenue increased $3.2 million in the fourth quarter of 2004 when compared to the fourth quarter of 2003. Days sales outstanding (DSO) in accounts receivable lengthened from 40 days for the year ended December 31, 2003 to 46 days when measured at December 31, 2004 primarily attributable to the increase in the sales volume generated in the latter part of the fourth quarter of 2004 as compared to the fourth quarter of 2003. Net inventory increased approximately $4.4 million from December 31, 2003. This increase was primarily due to increased levels of production in the fourth quarter which was geared to meet revenue at a level comparable with our expected rates of growth and the introduction of our new product, the Waterlase MD during the fourth quarter of 2004. Inventory turnover declined to 4.1 turns per year when measured at December 31, 2004 compared to 5.3 (restated) turns per year when measured at December 31, 2003. As increased efficiencies in the manufacturing process of the Waterlase MD occur, we believe we will be able to manage inventory levels consistent with revenue growth.

Principal among the changes in assets and liabilities which provided cash were accounts payable, accrued liabilities and deferred revenue. Accounts payable increased $3.4 million in relation to the growth in the business year over year. In addition, we incurred an obligation for 2005 insurance premiums at the end of 2004, a portion of which is reflected in accounts payable. Deferred revenue increased $1.2 million during the year due to certain deliverables we must provide under customer purchase orders. The customer is billed for these deliverables at the time of product shipment. An example of a future deliverable is training. Of these obligations, approximately $493,000 will expire if the customer does not utilize them within six months from the time the product shipped. Revenue is recorded when these deliverables are satisfied.

Several key indicators of liquidity are summarized in the following table (in thousands, except ratio amounts):

On March 3, 2004, we completed a public offering of 2.5 million shares of common stock. Net proceeds from the offering were $41.9 million. We incurred legal, accounting and related costs of approximately $1.5 million which we had recorded as a reduction to additional paid-in capital upon closing. We used a portion of the net proceeds to repay $1.8 million on the line of credit and $888,000 in debt. The balance was invested in marketable securities consisting of U.S. Treasury Bills with durations not exceeding two years. The balance of the net proceeds of the offering have been used for general corporate purposes, working capital, and capital expenditures, including expenditures for expansion of our production capabilities, and the acquisition or investment in complementary businesses or products or the right to use complementary technologies. In addition, the Board of Directors concluded that a stock repurchase program represented a use of capital that could enhance stockholder value. Therefore, in July of 2004, we announced a stock repurchase program to acquire up to 1.25 million shares over the next 12 months. In August of 2004, the Board of Directors authorized the repurchase of an additional 750,000 shares of our common stock, increasing the total share repurchase program to 2.0 million shares of our common stock. As of December 31, 2004 we had repurchased on the open market substantially all of the 2.0 million shares at an average price of $8.35 per share. Also in July of 2004, the Board of Directors established a dividend policy to pay a regular cash dividend of $0.01 per share every other month when declared by the Board of Directors. The first dividend totaling $235,000 was declared on July 27, 2004 and paid on August 30, 2004 to stockholders of record on August 16, 2004. The second dividend totaling $229,000

was declared on October 7, 2004 and paid on October 27, 2004 to stockholders of record on October 13, 2004. The third dividend totaling $225,000 was declared on December 9, 2004 and paid on December 29, 2004 to stockholders of record on December 15, 2004. The fourth dividend totaling $229,000 was declared in February 2005 and paid on February 24, 2005 to stockholders of record on February 10, 2005. The fifth dividend totaling $230,000 was declared in April 2005 and paid on May 9, 2005 to stockholders of record on April 25, 2005. The sixth dividend totaling $230,000 was declared in June 2005 and paid on June 28, 2005 to stockholders of record on June 12, 2005. On August 22, 2005, we announced that our Board of Directors voted to discontinue our current dividend policy of paying a cash dividend of $0.01 per share every other month.

At December 31, 2003, we had $1.8 million outstanding under a $5.0 million revolving credit facility with a bank, which was due to expire at June 30, 2004. In the first quarter of 2004, we used a portion of the net proceeds from our March 3, 2004 public offering to repay the $1.8 million outstanding on the line of credit. As of December 31, 2004, there were no amounts borrowed on the credit facility, however the facility was used and paid down at various times during the year. Borrowings under the facility bear interest at LIBOR plus 2.25% for minimum borrowing amounts of $500,000 and with two business days notice or at a variable rate equivalent to Prime rate for amounts below $500,000 or with less than two business days notice and are payable on demand upon expiration of the facility. All borrowings during 2004 were at Prime rate. Borrowings also subject us to certain covenants, including, among other things, maintaining a minimum balance of cash (including investments in U.S. Treasuries) and tangible net worth, a specified ratio of current assets to current liabilities and a covenant to remain profitable. In June 2004, this credit facility was extended to June 30, 2005 and increased to $10.0 million. In June 2005, this credit facility was extended to September 30, 2005. We were compliant with the covenants under the agreement with the exception to remain profitable on a quarterly basis. In February 2005, we notified our bank that we were in default under our covenants as of December 31, 2004 due to our operating loss for both the three months ended September 30, 2004 and December 31, 2004. In February 2005, we obtained a waiver to this covenant as of December 31, 2004. A similar waiver was obtained for our third quarter of 2004. As of April 20, 2005 we became non-compliant with our covenant relating to timely reporting and certification requirements due to the late filing of our Form 10-K for the year ended December 31, 2004. In July 2005, we obtained a waiver to this covenant and subsequently filed our Form 10-K on July 19, 2005.

On May 21, 2003 we acquired the American Dental Laser product line from American Medical Technologies, Inc., or AMT, for approximately $5.8 million. The assets acquired included dental laser patents, customer lists, brand names and other intellectual property as well as laser products. No outstanding debt of AMT was assumed in the transaction. The consideration paid by us consisted of approximately $1.8 million cash, $215,000 in transaction costs directly attributable to the acquisition and 307,500 shares of common stock with a fair value of approximately $3.8 million. For purposes of computing the purchase price, the value of the common stock of $12.38 per share was determined by taking the average closing price of our common stock as quoted on the Nasdaq National Market between May 19, 2003 and May 23, 2003.

In January 2005, we acquired the intellectual property portfolio of Diodem, consisting of certain U.S. and international patents of which four were asserted against us, and settled the existing litigation between us and Diodem, for consideration of $3,000,000 in cash, 361,664 shares of common stock, (valued at the common stock fair market value on the closing date of the transaction for a total of approximately $3,500,000), and a five-year warrant exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share. In addition, if certain criteria specified in the purchase agreement are satisfied on or before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. The common stock issued, the escrow shares and the warrant shares have certain registration rights. The total consideration was estimated to have a value of approximately $7,000,000 excluding the value of the shares held in escrow, but including the value of the patents acquired in January 2005. As of December 31, 2004, we accrued approximately $6,400,000 for the settlement of the existing litigation with $3,000,000 included in current liabilities and $3,400,000 recorded as a long-term liability. In January 2005, we recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent

infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products.

Recent Accounting Pronouncements

accounting changes and error corrections. It establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to the newly adopted accounting principle. SFAS No. 154 also provides guidance for determining whether retrospective application of a change in accounting principle is impracticable and for reporting a change when retrospective application is impracticable. The correction of an error in previously issued financial statements is not an accounting change. However, the reporting of an error correction involves adjustments to previously issued financial statements similar to those generally applicable to reporting an accounting change retrospectively. Therefore, the reporting of a correction of an error by restating previously issued financial statements is also addressed by SFAS No. 154. SFAS No. 154 is required to be adopted in fiscal years beginning after December 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

In December 2004, the FASB issued FASB Staff Position FAS No. 109-1, “Application of FASB Statement No. 109, ‘Accounting for Income Taxes,’ to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004” (“AJCA”). The AJCA introduces a special 9% tax deduction on qualified production activities. FAS No. 109-1 clarifies that this tax deduction should be accounted for as a special tax deduction in accordance with Statement No. 109. Pursuant to the AJCA, we will not be entitled to this special deduction in 2005, as the deduction is applied to taxable income after taking into account net operating loss carryforwards, and we have significant net operating loss carryforwards that will fully offset taxable income. We do not expect the adoption of this new tax provision to have a material impact on our consolidated financial position, results of operations or cash flows.

In December 2004, the FASB issued FASB Staff Position FAS No. 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creations Act of 2004.” The AJCA introduces a limited time 85% dividends received deduction on the repatriation of certain foreign earnings to a U.S. taxpayer (repatriation provision), provided certain criteria are met. FAS No. 109-2 provides accounting and disclosure guidance for the repatriation provision. To achieve the deduction, the repatriation must occur by the end of 2005. We have not completed our analysis and do not expect to be able to make a decision on the amount of such repatriations, if any, until the fourth quarter of 2005. Among other things, the decision will depend on the level of earnings outside the United States, the debt level between our U.S. and non-U.S. affiliates, and administrative guidance from the Internal Revenue Service.

In December 2004, the FASB revised and reissued SFAS No. 123-R, “Share-Based Payment,” which supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.” The revised statement addresses the accounting for share-based payment transactions with employees and other third parties, eliminates the ability to account for share-based payment transactions using APB No. 25 and requires that the compensation costs relating to such transactions be recognized in the consolidated statement of operations. The standard was to become effective July 1, 2005. In March 2005, the SEC released Staff Accounting Bulletin (“SAB”) No. 107, “Share-Based Payment,” to provide public companies additional guidance in applying the provisions of SFAS No. 123-R. Among other things, the SAB describes the staff’s expectations in determining the assumptions that underlie the fair value estimates and discusses the interaction of SFAS No. 123-R with certain existing staff guidance. SAB No. 107 should be applied upon the adoption of SFAS No. 123-R. In April 2005, the SEC amended Regulation S-X to provide a six-month adoption deferral period for public companies. Therefore, SFAS No. 123-R will not become effective for us until January 1, 2006. The new rules provide for one of two transition elections, either prospective application or restatement (back to January 1, 1995). We adopted SFAS No. 123-R on January 1, 2006. We currently are evaluating the impact of this pronouncement on our consolidated financial position, results of operations and cash flows.

in the cost of inventory. As amended by SFAS No. 151, the “so-abnormal” criterion has been eliminated. Thus, all such (abnormal) costs are required to be treated as current-period charges under all circumstances. In addition, fixed production overhead should be allocated based on the normal capacity of the production facilities, with unallocated overhead charged to expense when incurred. SFAS No. 151 is required to be adopted for fiscal years beginning after June 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

Quantitative and Qualitative Disclosures About Market Risk

Our net revenue in Europe is denominated principally in Euros, and our net revenue in other international markets is denominated in dollars. As a result, an increase in the relative value of the dollar to the Euro would lead to less income from revenue denominated in Euros, unless we increase prices, which may not be possible due to competitive conditions in Europe. Additionally, since expenses relating to our manufacturing operations in Germany are paid in Euros, an increase in the value of the Euro relative to the dollar would increase the expenses associated with our German manufacturing operations and reduce our earnings.

We currently have a line of credit in the amount of $10.0 million at the variable interest rate equivalent to the Prime rate for advances less than $500,000 and with less than two business days notice, and at LIBOR plus 2.25% for advances of $500,000 or more and with two business days notice. This line of credit currently expires on September 30, 2006. At September 30, 2005, we had an outstanding debt balance of $5.0 million.

Our primary objective in managing our cash balances has been preservation of principal and maintenance of liquidity to meet our operating needs. Most of our excess cash balances are invested in a money market account and U.S. treasury securities in which there is minimal interest rate risk.

Controls and Procedures

Management’s Report on Internal Control over Financial Reporting

The management of BIOLASE Technology, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004. In making this assessment, management used the criteria set forth in the framework established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) entitled “Internal Control—Integrated Framework.”

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Management has identified the following material weaknesses:

As of December 31, 2004, we did not maintain a sufficient complement of personnel with an appropriate level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with our financial reporting requirements. Specifically, we had deficiencies in accounting staff with sufficient depth and skill in the application of U.S. generally accepted accounting principles to meet the objectives that should be expected of these roles. This material weakness contributed to the following individual material weaknesses as of December 31, 2004.

We did not maintain effective controls over the accounting for taxes other than income taxes. Specifically, our controls failed to: (i) identify the existence of a liability for penalties and interest on amounts collected from customers that were not timely remitted to the states or have not been remitted to the states, and (ii) account for the gain on the abatement of certain penalties and interest. In addition, our controls failed to prevent or detect erroneous value added tax refunds that were incorrectly recorded as a receivable. This control deficiency resulted in an understatement of the sales tax and value added tax liabilities and general and administrative expense, which also resulted in the restatement of our annual 2002 and 2003, and first, second and third quarter 2004 consolidated financial statements.

We did not maintain effective controls over the identification of events that would trigger the need for an impairment analysis for indefinite-lived and long-lived assets. Specifically, our controls were ineffective in their design and operation to timely identify and evaluate the impact of a change in circumstances that resulted in the impairment of an acquired trade name. This control deficiency resulted in an adjustment to intangible assets and operating expenses in our fourth quarter 2004 consolidated financial statements.

We did not maintain effective controls over certain aspects of revenue recognition. Specifically, we did not have effective controls over: (i) revenue recognized on multiple element arrangements that included spares and consumables not shipped as of the balance sheet date, and (ii) the deferral of revenue on units that were not fully functional at the time revenue was recognized. This control deficiency resulted in premature revenue recognition and an adjustment to deferred revenue and revenue in 2003 and in each of the four quarters of the 2004 consolidated financial statements.

We did not maintain effective controls over the valuation of our inventory. Specifically, we did not have effective controls to: (i) identify slow-moving and obsolete inventory, and (ii) ensure our inventory was properly recorded at historical cost. This control deficiency resulted in adjustments to inventory and cost of revenue in our first and fourth quarter 2004 consolidated financial statements.

We did not maintain effective controls over accounts payable, certain accrued liabilities and the related expense accounts. Specifically, we did not have effective controls over the completeness, valuation and existence of accounts payable, accrued commissions and bonuses payable, and the related expense accounts. This control deficiency resulted in adjustments to our consolidated financial statements for each of the four quarters in 2004.

We did not maintain effective controls over the accounting for foreign currency translation. Specifically, we did not have effective controls over the use of appropriate exchange rates for consolidating the financial statements of our Germany operations. This control deficiency resulted in adjustments to our second, third and fourth quarter 2004 consolidated financial statements.

Additionally, each of these control deficiencies could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim financial statements that would not be prevented or detected.

As of December 31, 2004, we did not maintain effective controls over our cash accounts and cash disbursements in Germany. Specifically, we did not: (i) maintain a proper segregation of duties over the approval and payment of vendor invoices at our operations in Germany (i.e., the same individual who had access to bank accounts also authorized purchases and approved cash disbursements, and certain vendor payments, although valid, were executed by unauthorized individuals), and (ii) have effective controls over the review of bank reconciliations and the completeness, accuracy and validity of cash transactions recorded in the general ledger. This control deficiency did not result in an adjustment to our consolidated financial statements. However, it could result in a misstatement to cash and other financial statement accounts that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

As of December 31, 2004, we did not maintain effective controls over the processing of transactions of our subsidiary in Germany performed by a third party. Specifically, we did not have effective controls over the completeness, valuation and existence of certain financial statement accounts in Germany, such as accounts payable, accrued expenses, and the related sales and marketing, and general and administrative expenses, that are maintained by a third party. This control deficiency did not result in an adjustment to our consolidated financial statements. However, this control deficiency could result in a misstatement to the aforementioned financial statement accounts that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

As of December 31, 2004, we did not maintain effective controls over the restriction of access to financial application programs and data. We did not have effective controls over access to application programs and the underlying financial data. Specifically, there were instances in which certain financial accounting personnel had inappropriate access to financial application programs and data and the activities of these individuals were not subject to independent monitoring. This control deficiency did not result in an adjustment to our consolidated financial statements. However, this control deficiency could result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

As of December 31, 2004, we did not maintain an effective control environment based on criteria established in “Internal Control—Integrated Framework” issued by the COSO. The financial reporting organizational structure was not adequate to support our activities. Deficiencies, such as an insufficient complement of personnel with an appropriate level of accounting knowledge, experience and training in the application of U.S generally accepted accounting principles have resulted in adjustments to the consolidated financial statements as discussed in Item 1 above. Item 1, together with the material weaknesses described in Items 2, 3, and 4 above indicate that we did not maintain an effective control environment as of December 31, 2004. These control deficiencies could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Because of these material weaknesses, management has concluded that we did not maintain effective internal control over financial reporting as of December 31, 2004, based on the criteria in Internal Control—Integrated Framework.

Management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Plan for Remediation of Material Weaknesses

Management has reviewed with the Audit Committee of the Board of Directors the internal control deficiencies that constitute significant deficiencies and material weaknesses in our internal control over financial reporting as of December 31, 2004.

Management has adopted, with the Audit Committee’s concurrence, certain remedial measures that are designed to improve our control environment and to address the material weaknesses described in Management’s Report on Internal Control over Financial Reporting. These remedial measures include, but are not limited to, the following:

The addition of properly qualified personnel in the areas of accounting, sales management, manufacturing administration and inventory control

The hiring of our new Vice President/Corporate Controller in mid-year 2004

The implementation of enhanced training for our finance and accounting personnel to familiarize them with our current and revised, where applicable, accounting policies and procedures

The hiring of a tax professional who will oversee all tax matters both within the United States and internationally

The establishment of policies and procedures to ensure the proper deferral of revenue for undelivered products and services associated with multiple element revenue arrangements

The implementation of proper segregation of duties—or adequate mitigating controls—in the area of accounts payable

The implementation of controls to ensure the timely and consistent reconciliation of all significant accounts on a quarterly or more frequent basis as deemed appropriate

The restructuring of the German facility which will include the addition of a regional financial management person and an assigned person from corporate to monitor, review and reconcile all German transactions and accounts

The establishment of written policies and procedures relating to the access to, and control over, our financial accounting systems

10.

The ultimate migration of our financial accounting information technology system application (“system”) to a more robust, current version that will, among other benefits, integrate the inventory management process with the accounting and reporting function. We will also leverage the new system to monitor system access and employee specific transactions utilizing an on-line audit function.

At the direction of, and in consultation with the Audit Committee, management currently is working to implement certain of the remedial measures and intends to implement the remaining remedial measures during the course of 2005 and 2006, with continued improvements being an ongoing exercise. While this implementation is underway, we are relying on extensive manual procedures and the utilization of outside accounting professionals. While we are implementing changes to our control environment, there remains a risk that the transitional procedures on which we are currently relying will fail to be sufficiently effective. Please see the section in this prospectus called “Business—Risk Factors—Our internal controls and procedures need to be improved.”

Changes in Internal Control over Financial Reporting

During the fourth quarter of 2004, our chief operating officer and interim chief financial officer was appointed as our chief executive officer, and we hired a new chief financial officer, John W. Hohener. In December 2005, Mr. Hohener resigned and we hired Richard L. Harrison as our chief financial officer. Due to the delayed filing of our Form 10-K for the fiscal year ended December 31, 2004, Forms 10-Q/A for the three quarters therein, and the first six months ended June 30, 2005, we have not yet implemented any additional Remedial Measures described in the Management’s Report on Internal Control Over Financial Reporting contained in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2004. Management intends to implement these measures during the course of 2005 and 2006. We had indicated in our Form 10-K for the fiscal year ended December 31, 2004 that if we failed to adequately remediate our material

weaknesses by the end of our fiscal year 2005, our management may be required to conclude that our internal control over financial reporting is ineffective for fiscal year 2005. We also indicated that if we failed to remediate our significant deficiencies in our fiscal year, our management likely will be required to conclude that those significant deficiencies have become material weaknesses. Subsequently in 2005, we have identified an additional material weakness as a result of our internal controls not operating effectively during the nine months ended September 30, 2005 related to our inventory control.

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) promulgated under the Exchange Act, as of September 30, 2005. In light of the material weaknesses referenced in Management’s Report on Internal Control over Financial Reporting and the additional material weakness noted above as of September 30, 2005, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of December 31, 2004 and September 30, 2005, our disclosure controls and procedures were not effective at ensuring that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms or (ii) that such information is accumulated and communicated to our management, including our principal executive and principal financial officer, as appropriate, to allow timely decisions regarding required financial disclosure. However, our Chief Executive Officer, as our principal executive officer, and our Chief Financial Officer, as our principal financial officer, believe that, once the Remedial Measures described above are implemented, our internal controls will be effective to address the internal control deficiencies described in Management’s Report on Internal Control over Financial Reporting and allow us to conclude that our disclosure controls and procedures are effective at a reasonable level of assurance at future filing dates. In addition, in light of the material weaknesses identified, we performed additional analysis and other post-closing procedures in connection with the preparation of our consolidated financial statements in accordance with generally accepted accounting principles. Accordingly, we believe that the financial statements included in this prospectus fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented.

Change in Accountants

On August 8, 2005, we engaged BDO Seidman, LLP as our new independent registered public accounting firm. During our two most recent fiscal years and through August 9, 2005, we did not consult with BDO Seidman, LLP with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, or any other matters or reportable events listed in Item 304(a)(2)(i) or (ii) of Regulation S-K.

BUSINESS

We are the world’s leading dental laser company. We are a medical technology company that develops, manufactures and markets lasers and related products focused on technologies for improved applications and procedures in dentistry and medicine. In particular, our principal products provide dental laser systems that allow dentists, periodontists, endodontists, oral surgeons and other specialists to perform a broad range of dental procedures, including cosmetic and complex surgical applications. Our systems are designed to provide clinically superior performance for many types of dental procedures, with less pain and faster recovery times than are generally achieved with drills, scalpels and other dental instruments. We have clearance from the U.S. Food and Drug Administration, or FDA, to market our laser systems in the United States and also have the necessary approvals to sell our laser systems in Canada, the European Union and certain other international markets. We are currently pursuing regulatory approval to market and sell our Waterlase^® system in Japan. Since 1998, we have sold approximately 4,000 Waterlase systems and more than 5,390 laser systems in over 45 countries.

Waterlase system. We refer to our patented interaction of water with laser as YSGG^™ Laser HydroPhotonics^™. YSGG is a shortened abbreviation referring to the unique crystal (Er, Cr: YSGG) laser used in the Waterlase system, which contains the elements erbium, chromium and yttrium, scandium, gallium and garnet. This unique crystal laser produces energy with specific absorption and tissue interaction characteristics optimized for dental applications. HydroPhotonics refers to the interaction of laser with water to produce energy to cut tissue. Through YSGG Laser HydroPhotonics, the Waterlase system can precisely cut hard tissue, such as bone and teeth, and soft tissue, such as gums, with minimal or no damage to surrounding tissue. The Waterlase system is one of the world’s best selling dental laser systems, and we estimate it currently accounts for a majority of all dental lasers sold worldwide.

The Diode system, together with our Waterlase system, offer practitioners a broad product line with a range of features and price points. We also manufacture and sell accessories and disposables for our laser systems, such as hand pieces, laser tips and tooth whitening gel. The Waterlase system comprised 84%, 83% and 77% of our net revenue for the years ended December 31, 2004, 2003 and 2002, respectively. The Diode system comprised 11%, 12% and 18% of our net revenue for the same periods. The Waterlase system comprised 83% and 81% of our net revenue for the nine months ended September 30, 2005 and 2004, respectively. The Diode system comprised 9% and 10% of our net revenue for the same periods.

We believe there is a large market for our products in the United States and abroad. According to the American Dental Association, there are over 160,000 practicing dentists in the United States. According to the World Federation of Dentistry, an international dental organization, there are at least 700,000 dentists worldwide, and we believe that a substantial percentage of them practice in major international markets outside the United States. The use of lasers in dentistry is growing. However, we believe only a small percentage of dentists currently use laser systems, and that there is a significant opportunity to increase sales of our products worldwide.

Our goal is to establish our laser systems as essential tools in dentistry and to continue our leading position in the dental laser market. Our sales and marketing efforts focus on educating dental professionals and patients on the benefits of our laser systems, particularly our Waterlase system. In 2002, we founded the World Clinical

Laser Institute, an association that includes prominent dental industry leaders, to formalize our efforts to educate and train dentists and surgeons in laser dentistry. We participate in numerous other symposia and dental industry events to stimulate demand for our products. We have also developed numerous relationships with dental schools, research facilities and dental institutions, in the United States and abroad, which use our products for education and training. We believe this will expand awareness of our products among new generations of dental professionals.

Company Background and Recent Events

From inception in 1987 until 1998, we were engaged primarily in the research and development of the use of water and laser technology. We were originally formed as Societe Endo Technic, SA, or SET, in 1984 in Marseilles, France, to develop and market various endodontic and laser products developed by Dr. Guy Levy, then chairman of the Endodontics Department at the University of Marseilles. In 1987, SET was moved to the United States and was merged with a public holding company, Pamplona Capital Corp. In 1994, we changed our name to BIOLASE Technology, Inc. Through the end of fiscal 2000, we were financed by approximately $42 million in stockholder investments through a series of private placements of stock and the exercise of warrants and stock options.

Since 1998, our objective has been to become the leading designer, manufacturer and marketer of laser systems for the dental industry. We have focused our efforts on receiving governmental clearances with the U.S. Food and Drug Administration as well as furthering the commercial success and viability of our water and laser technology via our direct sales campaign initiatives, intellectual property advancements and strategic acquisitions. In 1998, we began the commercialization of our systems based on water and laser technology.

The selective pursuit of acquisitions represents an important component of our business strategy. We focus primarily on those candidates that will enable us to consolidate positions of leadership in our existing markets, further develop our portfolio of intellectual property, expand our strategic partnerships with leading companies and increase our capability and capacity to derive value for our customers and stockholders.

In December 2001, we formed BIOLASE Europe GmbH, a wholly owned subsidiary based in Germany. In February 2002, BIOLASE Europe acquired a laser manufacturing facility in Germany and commenced manufacturing operations at that location. This acquisition has enabled us to initiate an expansion of our sales in Europe and neighboring regions. We purchased the facility for cash consideration in October 2003 for approximately €986,000 (approximately $845,000) plus applicable taxes.

On May 21, 2003, we acquired the American Dental Laser product line and other dental laser assets of American Medical Technologies, Inc., or AMT, for approximately $5.8 million. The acquired assets included dental laser patents, customer lists, brand names and other intellectual property as well as laser systems, including the DioLase and Pulsemaster^® systems.

In May 2004, we launched the DioLase Plus^™ laser system, which is our first dental laser product that resulted from the integration of the American Dental Laser value proposition and BIOLASE’s cutting-edge technology platform. The DioLase Plus is a fully-featured, entry-level cosmetic, soft tissue and periodontal laser. The DioLase Plus delivers more power and features than competing entry-level diode lasers, with 7 watts of power vs. 3-5 watts found in competing systems. The DioLase Plus has many cosmetic and soft tissue applications; soft tissue curettage; laser removal of diseased, infected, inflamed and necrosed soft tissue within the periodontal pocket; and removal of highly inflamed edematous tissue affected by bacteria penetration of the pocket lining and junctional epithelium.

In May 2004, we opened our new manufacturing facility in San Clemente, California. The new facility is located adjacent to our headquarters. The building brings our U.S. leased facility capacity to approximately 40,000 square feet.

In July 2004, we announced a dividend policy to pay a regular cash dividend of $0.01 per share every other month payable to the stockholders of record at the time when declared by the Board of Directors. In August 2005, we discontinued this dividend policy.

In October 2004, we launched the Waterlase MD^™, a new clinical and technological platform for dentistry. The Waterlase MD, which features our exclusive, proprietary technology, has a very broad range of clinical capabilities both in dentistry and other medical disciplines. The Waterlase MD platform is intended to deliver on the “wish list” of clinical capabilities requested by dentists and comfort sought by patients. Notable features include the HydroBeam^™ LED illumination with a contra-angle 360 degree rotating handpiece as well as a SensaTouch^™ laser control system with easy touch screen functionality. The new system provides powerful cutting action, allowing the dentist to select up to 50 pulses per second. Another key advancement of the new system is two distinct pulse modes. Dual-mode capability gives the dentist the ability to do procedures with more comfort and control. These new features coupled with innovative, ergonomic styling and design are part of our proprietary MD technology platform upon which the Waterlase MD is based. The Waterlase MD all-tissue dental laser is the new premium price-point product of our dental laser product portfolio, serving to expand our existing dental laser product line.

In January 2005, we acquired the intellectual property portfolio of Diodem, consisting of certain U.S. and international patents of which four were asserted against us, and settled the existing litigation between us and Diodem for consideration of $3.0 million in cash, 361,664 shares of common stock, and a five-year warrant exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share. In addition, if certain criteria specified in the purchase agreement are satisfied on or before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. These escrowed shares had a fair market value of $500,000 at the time of the Binding Letter of Intent. The total consideration was estimated to have a value of $7.0 million, excluding the value of the shares held in escrow. As of December 31, 2004, we accrued $6.4 million for the settlement of the existing litigation. In January 2005, upon payment of the consideration, we also recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents or certain other patents held by us are licensed to a third party.

More recently, we have embarked on conducting research and development activities outside the field of dentistry. In particular, we have been researching a laser procedure for the permanent reversal of presbyopia, which is the phenomenon of natural aging that results in the loss of near-reading ability over the age of 40 years old. According to the Wall Street Journal article “Reading the Fine Print,” published on February 14, 2005, 110 million Americans suffer from presbyopia. In March 2005, we acquired a fully paid license related to patents owned or licensed by SurgiLight, Inc. As a result of the acquisition, we received fully paid license rights in the U.S. and International markets to patents in the field of presbyopia and other patents related to the field of ophthalmology. We acquired the fully paid license for a total consideration of $2.0 million in cash, of which $1.8 million was paid during the first quarter of 2005 and $200,000 will be expensed as incurred in 2006 through 2010, in accordance with FAS No. 2. This payment was recorded as research and development expense under the provisions of SFAS No. 2 as the technology is solely used for our research and development function and has no alternative future use to us.

Industry Background

General

More than 200 million hard tissue procedures are performed annually in the United States, according to a 2001 survey, released in 2003, by the American Dental Association. Hard tissue procedures include cavity preparation, inlays, crowns, root canals and other procedures involving bone or teeth. Based on this survey, more than 1.2 million soft tissue procedures are performed annually in the United States. Soft tissue procedures include gum line alteration, gum grafts and other procedures involving soft dental tissue. According to statistics compiled by the American Dental Association, over 90% of hard tissue procedures and 60% of soft tissue procedures in the United States are performed by general dentists, and the rest are performed by oral surgeons, periodontists and other specialists.

The American Dental Association estimates that the demand for dental services in the United States will continue to grow due to population growth and the increased awareness of the benefits associated with preventive dentistry in reducing the incidence of oral disease. According to the American Dental Association, annual expenditures in the United States in 2002 for dental treatment costs were $70 billion, and are expected to increase to approximately $100 billion by 2010.

Recently, the emergence of popular reality television programming focused on “extreme makeovers” has resulted in a growing awareness among consumers of the value and importance of a healthy smile. As such, the dental industry has entered an era of growth and consideration of advanced technologies that allow dentists to perform simple or complex cosmetic dental procedures with minimal trauma, patient acceptance and clinically superior results. We believe our product mix corresponds with this trend, and we expect incremental growth from these pressures in the marketplace.

Traditional Dental Instruments

Dental procedures are performed on hard tissue, such as bone and teeth, and soft tissue, such as gum and other oral tissue. Dentists and other specialists choose from a variety of instruments depending on the tissue involved and the type of procedure. Most procedures require the use of multiple instruments to achieve the desired result.

High Speed Drills. Most dentists use high speed drills for hard tissue procedures, such as preparing cavities for filling and gaining access for performing root canals or shaving and contouring oral bone tissue. Adverse effects associated with drills include thermal heat transfer, vibration, pressure and noise. The cutting and grinding action of high speed drills can cause damage to the patient’s dental structure. Additionally, this grinding action of high speed drills on teeth can potentially provide an entry point for the bacteria that causes tooth decay and weakens the tooth’s underlying structure, which leads to fractures and broken cusps. Crowns and root canals may become necessary as a result of damage caused during previous dental procedures.

Cutting Instruments. Soft tissue procedures, such as reshaping gum lines and grafting on new gum tissue, are typically performed by oral surgeons or periodontists using scalpels, scissors and other cutting tools. Due to the pain and discomfort associated with procedures performed with these instruments, most soft tissue procedures require the use of local anesthetic which results in numbness and discomfort, and often require stitches. Use of scalpels, scissors and other cutting tools typically cause bleeding, post-operative swelling and discomfort. Bleeding reduces the practitioner’s visibility and efficiency, and generally makes procedures more cumbersome. Bleeding is a particular problem for patients with immune deficiencies or blood disorders, and patients taking blood-thinning medications.

Alternative Dental Instruments

Alternative technologies have been developed over the years to address the problems associated with traditional methods used in dentistry. Most alternatives have addressed either hard or soft tissue applications. The predominant alternative technologies and their limitations are discussed below.

Air Abrasion Systems. Air abrasion systems were introduced as an alternative to the high speed drill for hard tissue procedures. Air abrasion systems blow a powerful air stream of aluminum oxide particles to erode hard tissue and remove the harder forms of decay. Air abrasion is most commonly used to repair cracks and discolorations, clean out pits and fissures, prepare cavities to be filled with composites and prepare tooth surfaces for bonding. However, air abrasion is not suitable for a variety of hard tissue procedures including bone, and cannot be used on, or very near to, soft tissue. In addition, the use of air abrasion is time consuming and scatters particles that can be inhaled by patients and staff, as well as damage equipment and instruments. Due to these limitations, we believe the popularity of these systems has declined over the last few years.

Electrosurge Systems. A commonly used technology, known as electro surge, was developed to cut soft tissue. Electro surge systems use an electrical spark that simultaneously cuts and cauterizes tissue, resulting in less bleeding than occurs with scalpels. Traditional electro surge results in deep penetration, which can cause unwanted damage to surrounding tissue, and is generally less precise than lasers. Electro surge is not suitable for hard tissue procedures and, due to the depth of penetration, generally requires use of anesthesia and involves a lengthy healing process. Use of most electro surge units is restricted near metal fillings and dental implants. Additionally, electro surge generally cannot be used with patients with implanted pacemakers and defibrillators.

Traditional Laser Systems. More recently, lasers have gained acceptance for use in general and cosmetic dentistry. Most lasers used in dentistry have been adapted from other medical applications, such as dermatology, and were not designed to perform a wide range of common dental procedures. Most dental lasers use thermal energy to cut tissue and are used primarily for soft tissue procedures.

Due to the limitations associated with traditional and alternative dental instruments, we believe there is a large market opportunity for dental laser systems that provide superior clinical results and help reduce the trauma, pain and discomfort associated with dental procedures.

The BIOLASE Solution

We believe the potential for increased patient satisfaction, improved outcomes and enhanced practice profitability that can be achieved through use of our products will position our laser systems as the instruments of choice among practitioners and patients for a broad range of dental procedures. We have developed our laser systems and related products specifically for the dental market to more effectively perform a broad range of dental procedures. The skill level and dexterity necessary to operate our laser systems are similar to those necessary to operate conventional drills and other dental equipment. Our laser systems also have the advantage of being able to perform procedures in narrow spaces where access for conventional instruments often is limited. Our systems are intended to complement traditional tools, such as dental drills, which perform functions that our systems do not address, such as cutting metal fillings and certain polishing and grinding functions.

Our primary product category, the Waterlase system, is one of the best selling dental laser systems in the world. The Waterlase system precisely cuts hard tissue, such as bone and teeth, and soft tissue, such as gums, with minimal or no damage to surrounding tissue and dental structure. Our Diode system is designed to complement the Waterlase system, and is used in soft tissue procedures and cosmetic applications, such as tooth whitening. The Diode system, together with our Waterlase system, offers practitioners a broad product line with a range of features and price points.

A small percentage of dental professionals worldwide currently use lasers. Moreover, our laser systems are more expensive than traditional dental tools. However, we believe that the significant performance advantages of our systems, the potential return on investment that our systems offer practitioners and the options available to finance the purchase of our systems will enable us to continue to penetrate the dental market segment.

We believe the demand for our systems will continue to expand as we increase awareness of the benefits to patients and dental professionals.

Benefits to Dental Professionals

•

Additional procedures through increased efficiency. Our systems often shorten and reduce the number of patient visits, providing dental professionals with the ability to service more patients. For hard tissue procedures, the Waterlase system reduces the need for anesthesia and enables dental practitioners to perform multiple procedures in one visit. An advantage of the Waterlase system is that it can be used to perform cavity preparations in multiple quadrants. In contrast, many dentists using high speed drills usually do not perform cavity preparations in more than one quadrant per visit because of concerns relating to use of anesthesia in multiple regions. For soft tissue procedures, the Waterlase and Diode systems allow tissue to be cut more precisely and with minimal bleeding. Additionally, our tooth whitening laser, LaserSmile, performs tooth whitening faster than competing non-laser systems due to its high power and fast activation of our proprietary whitening gel.

•

Expanded range of procedures and revenue opportunities. Our laser systems often allow general dentists to perform surgical and cosmetic procedures that they are unable or unwilling to perform with conventional methods, and which would typically be referred to a specialist. These procedures include crown lengthening, frenectomy and biopsy. Our systems allow dentists to perform these procedures easily and efficiently, increasing their range of skills and professional satisfaction.

•

Increased loyalty and expanded patient base. We believe the improved patient comfort and convenience offered by our systems will improve patient retention, attract new patients and increase demand for elective procedures.

•

Fewer post-operative complications. Our laser systems can reduce trauma, swelling and general discomfort, resulting in fewer post-operative complications that require follow up treatment. Practitioners can devote time to new cases, rather than treating complications from prior procedures.

Benefits to Patients

•

Comfort. With our Waterlase system, patients can experience dramatically improved comfort during and after most procedures. In most cases, procedures can be performed without local anesthesia, which eliminates the pain associated with injections and the feeling of numbness following the procedure.

•

Convenience. Dentists generally prefer to perform procedures that require local anesthesia in no more than one or two quadrants of the mouth in a single visit because of concerns related to the use of local anesthesia in multiple quadrants. Our Waterlase system does not require anesthesia in most cases, which allows procedures to be performed in multiple quadrants during a single office visit. This reduces the number of visits necessary to complete the patient’s treatment plan.

•

Reduced trauma. Trauma to the dental structure can be reduced because the Waterlase system avoids the thermal heat transfer, vibration and grinding action associated with the high speed dental drill. For soft tissue applications, our laser systems cut with more precision and less bleeding than typically achieved with conventional instruments.

•

Broader range of available procedures. Due to the improved comfort and convenience of our Waterlase system, we believe patients are more likely to consider cosmetic and other elective procedures that would generally be time consuming and uncomfortable.

Business Strategy

Our objectives are to increase our leadership position in the dental laser market and to establish our laser systems as essential tools in dentistry. Our business strategy consists of the following key elements:

•

Increase awareness of our laser systems among dental practitioners and patients. We intend to further penetrate the dental market by educating dental practitioners and patients about the clinical benefits of our laser systems, particularly the Waterlase system. We plan to increase adoption of our laser systems

by practitioners through our continued participation in key industry trade shows, the World Clinical Laser Institute, dental schools and other educational forums. We also intend to market our systems to practitioners through our direct sales force and advertising. We have recently begun and plan to continue our marketing efforts aimed directly at patients.

•

Expand sales and distribution capabilities. In the United States, we intend to continue to build a direct sales force and marketing team. Internationally, we intend to use established dental and medical device distributors and to use a direct sales force in select countries. We are developing an infrastructure to support growth in sales and marketing. This infrastructure includes information technology systems and personnel to manage our sales force, compile sales and marketing data and better serve our customers and distributors.

•

Expand product platform and applications. We plan to expand our product line and product applications by developing product enhancements and new laser technologies. Additionally, we may strategically acquire complementary products and technologies. For example, we acquired the American Dental Laser product line, which has enabled us to increase market penetration by offering a broad line of laser systems with a range of features and price points.

•

Continue high quality manufacturing and customer service. Our manufacturing operations in California and Germany are focused on producing high quality dental laser systems. We intend to continually develop and refine our manufacturing processes to increase production efficiencies and product quality. We provide high quality maintenance and support services through our support hotline and dedicated staff of in-house and field service personnel. Additionally, we plan to maintain and expand our network of factory-trained service technicians to provide maintenance and support services to customers in Europe and other markets outside the United States.

•

Strengthen and defend technology leadership. We believe our proprietary Waterlase system and YSGG Laser HydroPhotonic technology represent significant advancements in dentistry. We will pursue the protection of our intellectual property rights by expanding our existing patent portfolio in the United States and abroad. We intend to strategically enforce our intellectual property rights worldwide.

Products

We have two principal product lines. Our family of products includes the Waterlase and Diode systems, which we developed through our own research and development.

We currently sell our products in over 45 countries. The U.S. Food and Drug Administration, or FDA, has cleared all of our laser systems for the applications listed below, which enables us to market the systems in the United States. Our systems have the CE Mark and may be sold in the European Union. Additionally, we have approval to sell our Waterlase system in Canada, Australia, New Zealand and other Pacific Rim countries.

Related Accessories and Disposable Products

We also manufacture and sell disposable products and accessories for our laser systems. Our Waterlase system uses disposable laser tips of differing sizes and shapes depending on the procedures being performed. We also market aftercare products, such as flexible fibers and hand pieces. Our Diode system also uses flexible fibers and hand pieces as well as tooth whitening gel kits for our LaserSmile system.

Warranties and Insurance

Our laser systems sold to end users and distributors are covered by one-year and fourteen-month warranties, respectively, against defects in material and workmanship. Our warranty covers parts and service for direct sales and parts only for distributor sales. We sell service contracts to our end users that cover the period after the expiration of our standard warranty coverage for our laser systems. Extended warranty coverage provided under our service contracts varies by the type of system and the level of service desired by the customer. In addition, we maintain product liability insurance with respect to our products with a general coverage limit of $12 million in the aggregate.

Manufacturing

We manufacture, assemble and test our products at manufacturing facilities located in San Clemente, California and Floss, Germany. We acquired our German manufacturing facility in 2002. We manufacture and install our systems and provide maintenance services for products sold in Europe and other international markets through both our California and German operations. Net revenue generated from products manufactured at our German facility accounted for 12% of our net revenue for the nine months ended September 30, 2005 and 8% of our net revenue for the comparable period in fiscal 2004. We are currently reviewing our need for manufacturing in Germany and may in the future decrease or eliminate our manufacturing operations there. However, we would retain our ability to manufacture our products in Germany.

We use an integrated approach to manufacturing, including the assembly of laser heads, electronics and cabinetry. We obtain components and subassemblies for our products from third party suppliers, most of which are located in the United States. We generally purchase components and subassemblies from a limited group of suppliers through purchase orders. We have no written supply contracts with our key suppliers. Three key components used in our Waterlase system, which accounted for approximately 84% of our net revenue in 2004, 83% of our net revenue in 2003 and approximately 77% of our net revenue in 2002, are each supplied by a separate single-source supplier. The Waterlase system comprised 83% and 81% of our net revenue for the nine months ended September 30, 2005 and 2004, respectively. A leading European supplier of precision hand tools manufactures the Waterlase hand pieces and the laser crystal and fiber components are each made by a separate supplier. We have not experienced material delays from the suppliers of these three key components and we have identified and tested alternative suppliers for each of these components. However, an unexpected interruption in a single source supplier could create manufacturing delays and disrupt sales as we take the necessary steps to replace the supplier, which we estimate could take up to three months.

Our manufacturing facilities are ISO 13485 certified. ISO 13485 certification provides guidelines for quality of company systems associated with the design, manufacturing, installation and servicing of company products. In addition, both the U.S. and German facilities are registered with the FDA and are compliant with the FDA’s Good Manufacturing Practice guidelines.

Marketing and Sales

Marketing

We currently market our laser systems in the United States, Canada, Australia and various countries throughout Europe and the Pacific Rim. Our marketing efforts are focused on increasing brand and specific product awareness among dental practitioners. We recently began efforts to increase awareness of the benefits of our products by marketing directly to patients.

Dental Practitioners. We currently market our laser systems directly to dental practitioners through regional, national and international trade publications, events, meetings and seminars. We also use brochures, direct mailers, press releases, posters and other promotional materials, as well as print and electronic media news coverage. In 2002, we founded the World Clinical Laser Institute to formalize our efforts to educate and train dental practitioners in laser dentistry. The Institute conducts and sponsors educational programs domestically and internationally for dental practitioners, researchers and academicians, including two or three-day seminars and training sessions involving in-depth discussions on the use of lasers in dentistry. In addition, we have developed relationships with research institutions, dental schools and clinical laboratories, which use our products in training and demonstrations. We believe these relationships will increase awareness of our products.

Patients. We recently began to market the benefits of our laser systems directly to patients through marketing and advertising programs, including print and broadcast media, local television news and radio spots, as well as product placements of our laser systems on popular reality television “makeover” programs. We believe that making patients aware of our laser systems and their benefits will increase demand for our products.

Sales

We currently sell our products primarily to dentists in general practice. The majority of the dentists in the United States, as well as the majority of our customers, are sole practitioners. We also expect our laser systems to gain acceptance among oral surgeons and other dental specialists, as they become better aware of the clinical benefits and new treatment options available through use of our laser systems.

International revenue accounts for a significant portion of our total revenue. International revenue accounted for approximately 19%, 20%, and 23% of our net revenue in 2004, 2003, and 2002, respectively. For the nine months ended September 30, 2005, international sales accounted for approximately 28% of our net revenue, as compared to approximately 27% of our net revenue for the same period in 2004. Net revenue in Asia, Latin America, Pacific Rim countries and Australia accounted for approximately 8%, 9%, and 12% of our net revenue in 2004, 2003, and 2002, respectively. Net revenue in Europe accounted for approximately 11%, 11%, and 11% of net revenue in 2004, 2003, and 2002, respectively.

Direct Sales. We sell products in the United States and Canada through our direct sales force, which is organized by region. As of September 30, 2005, we had 35 direct sales staff in North America and 7 direct sales staff covering Europe. Each of our direct sales employees receives a base salary and commissions on sales. We plan to expand our direct sales force in territories that represent growing markets.

Distributors. Except for sales in Canada, Germany, Spain and Italy, we sell products outside the United States primarily through a network of independent distributors located in Europe, Asia and Australia. Generally, our distributors enter into exclusive agreements in which they purchase systems and disposables from us at a wholesale dealer price and resell them to dentists in their sales territories. All sales to distributors are final and we can terminate our arrangements with dealers and distributors for cause or non-performance. We have exclusive arrangements with certain distributors for select territories, under which distributors are generally required to satisfy certain minimum purchase requirements to maintain exclusivity. Typically, sales to new distributors are generally paid in advance or secured with a letter of credit.

Seasonality. We have experienced a distinct seasonal pattern over the past several years. The fourth quarter, ending December 31, has generally been the strongest quarter, and in 2004 accounted for approximately 32% of our 2004 revenue. By contrast, the first quarter is generally the slowest sales quarter and in 2004 accounted for only 24% of our 2004 revenue. The second quarter is generally stronger than the first quarter however in 2004, it also accounted for approximately 24% of our 2004 revenue. The third quarter has generally been flat to down compared to the second quarter, accounting for approximately 20% of our revenue in 2004. However, this pattern of seasonality did not materialize in 2005, we believe, because purchasing decisions have been delayed due to associated design changes of our Waterlase MD.

During 2004, our third quarter was significantly impacted by two items. We believe that many customers delayed purchasing decisions pending the anticipated launching of our new Waterlase product, the Waterlase MD. In addition, some of our U.S. trade shows and seminars were impacted in the southeast by the region’s major hurricanes. Trade shows and seminars are a significant sales-generating process for us. As a result of this seasonality, our growth metrics compare growth in a quarter to the same quarter in the prior year and are not focused on growth in consecutive quarters which has been and we expect will continue to be skewed by this seasonality effect.

Customer Service. We provide maintenance and support services through our support hotline, service personnel and network of factory-trained service technicians. We provide maintenance and support services in the United States and Germany through our employee service technicians. We train and maintain a network of service technicians trained at our factory locations, who provide maintenance and support services in all other countries where we do business. Our distributors are responsible for providing maintenance and support services for products sold by them. We provide parts to distributors at no additional charge for products covered under warranty.

Financing Options. Many dentists finance their purchases through third-party leasing companies or banks. In these transactions, the dentist first enters into a purchase order with us. We then enter into a purchase order with the leasing company, which purchases the product from us, and the dentist enters into a lease agreement with the leasing company. We receive payment in full for the product at the time of purchase from the leasing company, and we are not a party to the lease. The dentist pays the leasing company or bank in installments, and we do not bear the credit risk that the dentist might not make payments. The leasing companies and banks do not have recourse to us for a dentist’s failure to make payments, nor do we have any obligation to take back the product at the end of the lease. Approximately 28% and 32% of our net revenue in 2004 and for the nine months ended September 30, 2005, respectively, was generated from sales to dentists who financed their purchase through National Technology Leasing Corporation, an equipment leasing broker. National Technology Leasing arranges financing through banks.

We have an agreement with National Technology Leasing under which we agreed to offer National Technology Leasing first right of refusal when dentists desire to use a finance or lease company. Our customers are under no obligation to finance the purchase or lease of any equipment through National Technology Leasing, and we refer only those customers that request a referral from us. In exchange, National Technology Leasing agreed to give us first priority on scheduling personnel in support of our sales functions, and on processing lease or financing transactions for our customers. National Technology Leasing further agreed to sponsor marketing programs from time to time for our benefit and the benefit of our customers. Additionally, National Technology Leasing agreed to accept the terms of our customer purchase order in transactions in which it is a party pursuant to the revised agreement entered into August 5, 2003. The agreement is for one year intervals and automatically renews if no action is taken to terminate. The agreement is now in effect until August 5, 2006. The agreement also may be terminated by either party upon 45 days written notice. If leasing arrangements were no longer available through National Technology Leasing or the banks with which it deals, we believe our customers would be able to obtain financing through a variety of other leasing companies or banks that frequently approach us to provide financing for our products.

Research and Product Development

Research and development activities are essential to maintaining and enhancing our business. We believe our research and development team has demonstrated its ability to develop innovative products that meet evolving market needs. Our research and development group consists of 12 individuals with medical device and laser development experience and other relevant backgrounds, the majority of whom have degrees in physics or engineering, including two Ph.Ds. During the years ended December 31, 2004, 2003 and 2002, our research and development expenses were approximately $3.6 million, $2.5 million and $1.7 million, respectively. Engineering and development expense for the nine months ended September 30, 2005 was $5.3 million, representing an increase of $2.8 million, compared to the same period of 2004. The increase in the nine month period is primarily the result of our acquiring a license to use certain patent rights totaling $2.0 million from Surgilight in the field of presbyopia and the related expenses of the transaction. We intend to focus our research and development activities on improving our existing products and extending our product range in order to provide dental practitioners and patients with less painful and clinically superior laser systems.

Intellectual Property and Proprietary Rights

We rely, in part, on a combination of patents, trademarks, trade secrets, copyrights and other intellectual property rights to protect our technology. We have 92 issued patents and numerous pending patent applications. Approximately two-thirds of our patents were granted in the United States, and the rest were granted in Europe and other countries around the world. Our patents cover the use of laser technologies and fluids for dental,

medical and industrial applications, as well as laser characteristics, accessories, future technological developments, fluid conditioning and other technologies and methods for dental, medical and aesthetic applications. We have numerous patent applications pending worldwide and plan to apply for other patents in the future as we develop new technologies. While we hold a variety of patents that cover a broad range of technologies and methods, approximately 67% of these patents provide market protection for our core technologies incorporated in our laser systems, including the Waterlase system, which accounted for approximately 84% of our net revenue in 2004 and approximately 83% of our net revenue in 2003. Our patents provide market protection for our core technologies and will end their lifetime given by the granting patent offices as follows: one in 2006, three in 2008, eleven in 2009, and the balance have expiration dates ranging from 2010 to 2022.

In January 2005, we acquired the intellectual property portfolio of Diodem, consisting of certain U.S. and international patents of which four were asserted against us, and settled the existing litigation between us and Diodem, for consideration of $3.0 million in cash, 361,664 shares of common stock, and a five-year warrant exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share. In addition, if certain criteria specified in the purchase agreement are satisfied on or before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. These escrowed shares had a fair market value of $500,000 at the time of the Binding Letter of Intent. The total consideration was estimated to have a value of $7.0 million, excluding the value of the shares held in escrow. As of December 31, 2004, we accrued $6.4 million for the settlement of the existing litigation. In January 2005, upon payment of the consideration, we also recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents or certain other patents held by us are licensed to a third party. In order to secure performance by us of these financial obligations, the parties entered into an intellectual property security agreement, pursuant to which, subject to the rights of existing creditors and the rights of any future creditors to the extent provided in the agreement, we granted Diodem a security interest in all of their right, title and interest in the royalty patents. In addition, we will be required, by January, 2006, to provide Diodem a ten-year letter of credit from a bank in the amount of $500,000 as additional security.

In March 2005, we acquired a fully-paid license related to patents owned or licensed by SurgiLight, Inc. As a result of the acquisition, we received fully-paid license rights in the U.S. and international markets to patents in the field of presbyopia and other patents related to the field of ophthalmology. We acquired the fully paid license for a total consideration of $2.0 million in cash, of which $1.8 million was paid during the first quarter of 2005 and $200,000 remains outstanding. This payment was recorded as research and development expense under the provisions of SFAS No. 2 as the technology is solely used for our research and development function and has no alternative future use to us.

Competition

We compete with a number of companies that market traditional dental products, such as dental drills, as well as other companies that market laser technologies in dental and other medical markets. In the domestic hard tissue dental market, we believe our Waterlase system primarily competes with laser systems manufactured by Hoya ConBio, a subsidiary of Hoya Photonics, a large Japanese manufacturer primarily of optics and crystals, and OpusDent Ltd., a subsidiary of Lumenis, an Israeli company. In the international market, our Waterlase system competes primarily with products manufactured by several other companies, including KaVo, Deka Dental Corporation and Fotona d.d.

The Waterlase system also competes with non-laser based systems, including traditional high and low-speed dental drills and air abrasion systems that are used for dental procedures. Our Diode system competes with other

semiconductor diode lasers, as well as with scalpels, scissors and a variety of other cutting tools that have been traditionally used to perform soft tissue procedures. In the market for tooth whitening, the LaserSmile competes with other products and instruments used by dentists, as well as tooth whitening strips and other over the counter products.

Traditional and commonly used cutting tools are less expensive for performing dental procedures. For example, a high speed drill or an electro surge device can be purchased for less than $1,000 each. However, we believe our systems offer substantial benefits that outweigh cost concerns. In addition, our systems are not designed to perform certain functions that high speed drills can perform, such as cutting metal fillings and certain polishing and grinding functions. High speed drills will still be needed for these functions, and our systems are not intended to replace all applications of the high speed drill.

In general, our ability to compete in the market depends in large part on our

•

product performance

•

product pricing

•

intellectual property protections

•

customer support

•

timing of new product research

•

development of successful national and international distribution channels

Some of the manufacturers that develop competing laser systems have greater financial, marketing and technical resources than we do. In addition, some competitors have developed, and others may attempt to develop, products with applications similar to those performed by our laser systems.

Government Regulation

Our products are medical devices. Accordingly, our product development, testing, labeling, manufacturing processes and promotional activities are regulated extensively by government agencies in the United States and other countries in which we market and sell our products. We have clearance from the FDA to market our laser systems in the United States. We have the clearances necessary to sell our WaterLase, Waterlase MD and LaserSmile laser systems in Canada. We also have the necessary CE Marks or clearances to sell our laser systems in the European Union and other international markets.

United States

In the United States, the FDA regulates the design, manufacture, distribution, quality standards and marketing of medical devices. We have clearance from the FDA to market our Waterlase and Diode systems in the United States for dental procedures on both adult and pediatric patients. In 1998, we received FDA clearance to market the Millennium^{^®}, the earlier generation of our current Waterlase system, for certain dental hard tissue applications. This clearance allowed us to commence domestic sales and marketing of our technology for hard and soft tissue applications. During 1999 and 2000, to meet the demand for soft-tissue and cosmetic dentistry applications, we designed a semiconductor diode laser system, which is now marketed as our LaserSmile system. We received FDA clearance to market the system for a variety of soft tissue medical applications in September 1999. In 2001, we received FDA clearance to market the LaserSmile system for cosmetic tooth whitening. In October 2003, the LaserSmile received clearance for periodontal procedures for both early and advanced stages of periodontal disease.

In 2002, 2003 and in January 2004, our Waterlase system became the first laser system to receive FDA clearance for several new types of dental procedures. In 2002, we received clearance to market the Waterlase

system for root canal, encompassing all four of the fundamental steps of the procedure. We also received clearance in 2002 to market this system for cutting, shaving, contouring and resection of oral osseous tissues, or bone. In January 2003, we received FDA clearance to market the Waterlase system for use in apicoectomy surgery, a procedure for root canal infections and complications that includes cutting gum, bone (to access the infected area) and the apex of the tooth to access the infected area. The clearance also encompasses flap surgical procedures. Flaps are frequently created in conjunction with many procedures, including periodontal, implant placement and recovery, extraction of wisdom teeth, and exposure of impacted teeth. In January 2004, our Waterlase system received FDA clearance for several new bone, periodontal and soft tissue procedures, including removal of bone to correct defects and create physiologic contours of bone, resection of bone to restore architecture, resection of bone for grafting, preparing full, partial and split thickness flaps for periodontal surgery and removal of granulation tissue from bony defects. Additionally, the Waterlase system became the first hard tissue laser to receive clearance for soft tissue curettage.

As we develop new products and applications or make any significant modifications to our existing products or labeling, we will need to obtain the regulatory clearances or approvals necessary to market such products for dental, cosmetic and other medical procedures in our target markets.

There are two principal methods by which FDA regulated devices may be marketed in the United States: pre-market approval, or PMA, and 510(k) clearance. A PMA application is required for a device that does not qualify for clearance under 510(k) provisions. The FDA is required by law to review a PMA application within 180 days, but the FDA typically takes much longer to complete the review. As part of the approval of a PMA application, the FDA typically requires human clinical testing to determine safety and efficacy of the device. To conduct human clinical testing, typically the FDA must approve an Investigational Device Exemption, or an IDE. To date, none of our products have required a PMA application to support marketing approval.

To obtain 510(k) clearance, we must demonstrate that our device is substantially equivalent to a previously cleared 510(k) device or a device that was in commercial distribution before May 28, 1976 for which the FDA has not yet called for the submission of PMA applications. By statute and regulation, the FDA is required to clear, deny or request additional information on a 510(k) request within 90 days of submission of the application. As a practical matter, 510(k) clearance often takes significantly longer. Domestic marketing of the product must be deferred until clearance is received from the FDA. In some instances, an IDE is required for clinical trials for a 510(k) clearance. If a request for 510(k) clearance is turned down by the FDA, then a PMA application may be required. We intend to utilize the 510(k) notification procedure whenever possible. To date, all of our regulated products have qualified for 510(k) clearance. In addition, in September 2005, we filed a 510(k) regulatory submission requesting marketing clearance from the FDA for our OCULASE MD™ laser, designed to perform various indications for use in the fields of ophthalmology and oculoplasty. The indications requested are for general tissue ablation, anterior capsulotomy (cataract removal), skin resurfacing and treatment of wrinkles of tissue surrounding the eye and orbit.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, will require a new 510(k) clearance, or could require a PMA application. The FDA requires each manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If the FDA disagrees with a manufacturer’s determination, the FDA can require the manufacturer to cease marketing and/or recall the modified device until 510(k) clearance or PMA is obtained.

After a device is placed on the market, numerous regulatory requirements apply. These include:

•

quality system regulations, or QSRs, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all aspects of the manufacturing process

•

labeling regulations, which prohibit the promotion of products for uncleared, unapproved or “off label” uses

•

medical device reporting regulations, which require that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur

•

correction and removal regulations, which require that manufacturers report to the FDA any corrections to or removals of distributed devices that are made to reduce a risk to health

•

post-market surveillance regulations, which apply when necessary to protect the public health or to provide additional safety and effectiveness data for the device

We will need to invest significant time and other resources to ensure ongoing compliance with FDA quality system regulations and other postmarket regulatory requirements.

We also are subject to unannounced inspections by the FDA for both the U.S. and BIOLASE Europe offices, and the Food and Drug Branch of the California Department of Health Services for our California manufacturing facilities, and these inspections may include the manufacturing facilities of our subcontractors.

Failure to comply with applicable regulatory requirements can result in an enforcement action by the FDA, which may include any of the following sanctions:

•

fines, injunctions and civil penalties

•

recall or seizure of our products

•

operating restrictions, partial suspension or total shutdown of production

•

refusing our request for 510(k) clearance of or PMA application for new products

•

withdrawing 510(k) clearance or PMA applications that are already granted

•

criminal prosecution

We are also subject to regulation under the Radiation Control for Safety and Health Act of 1968, or the Safety Act, administered by the FDA. The Safety Act regulates the energy emissions of light and sound and electronic waves from electronic products. Regulations implementing the Safety Act require a laser manufacturer to file new product and annual reports, to maintain quality control, product testing and sales records, to distribute product operation manuals, to incorporate certain design and operating features in lasers sold to end users and to certify and label each laser sold to end users as one of four classes of lasers based on the level of radiation emitted from the laser. In addition, various warning labels must be affixed to the product and certain protective features must be installed, depending upon the class of product.

Various state dental boards are considering the adoption of restrictions on the use of lasers by dental hygienists. Approximately 30 states currently allow dental hygienists to use lasers to perform certain dental procedures. In addition, dental boards in a number of states are considering educational requirements regarding the use of dental lasers. The scope of these restrictions and educational requirements is not now known, and they could have an adverse effect on sales of our laser-based products.

International

Foreign sales of our laser-based products are subject to the regulatory requirements of the foreign country or, if applicable, the harmonized standards of the European Union. These regulatory requirements vary widely among countries and may include technical approvals, such as electrical safety, as well as demonstration of clinical efficacy. We have a CE Mark for our Waterlase MD, Waterlase and LaserSmile systems, which permits us to commercially distribute these systems throughout the European Union. We rely on export certifications from the FDA to comply with certain regulatory requirements in several foreign jurisdictions, such as New Zealand, South Korea and countries in Latin America. We also received clearance to market our Waterlase and

LaserSmile systems in Canada and Australia for a variety of applications. We are currently working to meet certain foreign country regulatory requirements for certain of our products, including those in Japan. There can be no assurance that additional approvals in Japan or elsewhere will be obtained.

Other Regulatory Requirements

In addition to the regulatory framework for product clearances and approvals, we are subject to extensive and frequently changing regulations under many other laws administered by U.S. and foreign governmental agencies on the national, state and local levels, including requirements regarding occupational health and safety and the use, handling and disposing of toxic or hazardous substances.

Third Party Reimbursement

Many procedures performed with our laser systems are covered by insurance to the same extent as they would be if performed using traditional dental instruments. Most therapeutic procedures performed with our laser systems are reimbursable to a certain extent under dental insurance plans, whereas cosmetic procedures are not. Market acceptance for our products depends, in part, on the availability of reimbursement within prevailing health care payment systems. Reimbursement and health care payment systems in international markets vary significantly by country, and include both government-sponsored health care and private insurance.

Employees

At September 30, 2005, we employed approximately 210 people, of which there are 77 in manufacturing and quality and control, 12 in research and development, 69 in sales and sales support, 24 in customer technical support and 28 in administration. Our employees are not represented by any collective bargaining agreement and we believe our employee relations are good.

Properties

Our corporate headquarters are located at 981 Calle Amanecer, San Clemente, California, where we lease 25,000 square feet of space for research and development and administrative functions. Additionally, we lease 14,500 square feet of space for manufacturing functions, which is located within the same corporate business park of our headquarters, at 1001 Calle Amanecer, San Clemente, California. The leases on these facilities expire on April 30, 2006. In January 2006, we entered into a 5-year lease for new corporate headquarters space in Irvine, California, consisting of 56,900 square feet of space. Our wholly owned subsidiary, BIOLASE Europe, owns a manufacturing facility totaling approximately 20,000 square feet of space in Floss, Germany. We believe that our facilities are sufficient for our current needs and that suitable additional or substitute space will be available as needed to accommodate foreseeable expansion of our operations. Other than the land and building in Germany, with a recorded net book amount of $1.2 million, the majority of our long-lived assets are located in the United States.

Legal Proceedings

duties by those individual defendants and by the members of our Board of Directors. The second amended complaint was dismissed without prejudice in January 2006, and the court gave the plaintiffs 30 days to amend their complaint. However, based on the facts presently known, our management believes we have meritorious defenses to these actions and intend to vigorously defend them. As of September 30, 2005, no amounts have been recorded in the consolidated financial statements for these matters since management believes that it is not probable we have incurred a loss contingency.

During the quarter ended March 31, 2005, we issued 361,664 shares of our common stock (valued at approximately $3.5 million) and a five-year warrant (valued at approximately $443,000) exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share, in addition to the $3.0 million cash payment, for the legal settlement with Diodem. In addition, if certain criteria specified in the agreement are satisfied before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. The common stock issued, the escrow shares and the warrant shares have certain registration rights and are being registered for resale in the registration statement of which this prospectus forms a part. The total consideration was estimated to have a value of approximately $7.0 million, excluding the value of the shares held in escrow which are contingent in nature, but including the value of the patents acquired in January 2005. As of December 31, 2004, we accrued approximately $6.4 million for the settlement of the existing litigation. In January 2005, we recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents held by us are licensed to a third party. In order to secure performance by us of these financial obligations, the parties entered into an intellectual property security agreement, pursuant to which, subject to the rights of existing creditors and the rights of any future creditors to the extent provided in the agreement, we granted Diodem a security interest in all of their right, title and interest in the royalty patents. In addition, we will be required, by January, 2006, to provide Diodem a ten-year letter of credit from a bank in the amount of $500,000 as additional security.

In late 2004, we were notified by Refocus Group, Inc., or Refocus, that certain of our planned activities in the field of presbyopia may infringe one or more claims of a patent held by Refocus. In February 2005, we filed a lawsuit in the U.S. District Court for the Central District of California against Refocus in order to obtain declaratory relief that certain of our planned activities in the field of presbyopia will not infringe the claims of a patent held by Refocus and/or that the claims are invalid. These claims were dismissed by the court in July 2005 without prejudice on the basis that we do not have a product that has been commercialized and, therefore, Refocus’ alleged infringement claims are not ripe. As of September 30, 2005, no amounts have been recorded in the accompanying consolidated financial statements for this matter since management believes that it is not probable we have incurred a loss.

From time to time, we are involved in other legal proceedings incidental to our business, but at this time we are not party to any other litigation that is material to our business.

Board Committees and Meetings

The Board of Directors held seven meetings and acted by written consent various times during the year ended December 31, 2004. The Board has an Audit Committee, a Compensation Committee and a Nominating Committee. Each director attended or participated in 75% or more of the aggregate of (i) the total number of meetings of the Board of Directors and (ii) the total number of meetings held by all committees of the Board on which such director served during 2004. In addition, the Board encourages each of the directors to attend the annual meeting of stockholders, and four of the five directors attended the 2004 annual meeting of stockholders.

Audit Committee. The Audit Committee currently consists of three directors, Messrs. d’Arbeloff and Pignatelli and Dr. Anderton, and is primarily responsible for approving the services performed by our independent registered public accounting firm and reviewing their reports regarding our accounting practices and systems of internal accounting controls. The committee also reviews our financial reports, its accounting and financial policies in general, and management’s procedures and policies with respect to our internal accounting controls. The Audit Committee held ten meetings during 2004 and acted by written consent various times during 2004.

The Board has determined that all members of the Audit Committee are “independent” as that term is defined in Rule 4200 of the NASDAQ Marketplace Rules and Section 10A of the Exchange Act and the rules and regulations thereunder. The Board has determined that Mr. d’Arbeloff qualifies as the “audit committee financial expert” under the Exchange Act, by means of his experience identified above.

Compensation Committee. The Compensation Committee currently consists of three directors, Messrs. Pignatelli and d’Arbeloff and Dr. Anderton, and is primarily responsible for reviewing and developing our general compensation policies and making recommendations to the Board of Directors on compensation levels for our executive officers. The Compensation Committee also reviews and makes recommendations to the Board of Directors on matters relating to employee compensation and benefit plans. Each of the members of our Compensation Committee qualifies as an independent director under the NASDAQ Marketplace Rules and as a non-employee director under the Internal Revenue Code. The Compensation Committee held one meeting during 2004.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee currently consists of three directors, Dr. Anderton and Messrs. d’Arbeloff and Pignatelli, and is primarily responsible for recommending to the Board of Directors criteria for membership on the Board of Directors, identifying individuals qualified to serve on the Board of Directors and recommending individuals for selection by the Board of Directors as director nominees for election at each annual meeting of stockholders. The Nominating and Corporate Governance Committee is also responsible for developing and recommending to the Board of Directors corporate governance guidelines and overseeing the annual evaluation of the Board of Directors. The Nominating and Corporate Governance Committee has a policy that it will review and evaluate the qualifications of any director candidates who have been recommended by our stockholders. A stockholder who wishes to suggest a prospective nominee for the Board should notify any member of the Nominating and Corporate Governance Committee in writing with any supporting material the stockholder considers appropriate. Each of the members of our Nominating and Corporate Governance Committee qualifies as an independent director under the NASDAQ Marketplace Rules and SEC rules and regulations. The Nominating and Corporate Governance Committee held two meetings during 2004.

Director Compensation

Non-employee directors did not receive any cash compensation from us for their service as members of the Board of Directors or any Board committee in 2004. However, directors are reimbursed for all reasonable travel and lodging expenses incurred by them in attending Board and committee meetings. As Chairman of the Board, Mr. Pignatelli receives a quarterly payment of $7,500 which approximates his actual expenses incurred in connection with his service on our Board of Directors. In addition, in June 2005, our Board of Directors resolved to make a one-time payment of $90,000 to Mr. d’Arbeloff in connection with his service as audit committee chair and the extraordinary efforts he contributed in connection with the 2004 audit.

Under the automatic option grant program in effect under the 2002 Stock Incentive Plan, each individual who is elected to the Board as a non-employee director, at an annual meeting of stockholders or at a special meeting at which directors are elected, automatically is granted, on the date of such election, a non-statutory option to purchase 30,000 shares of common stock. Each option vests at a rate of 7,500 shares per quarter, commencing three months after the date of grant. If a non-employee director becomes a director for the first time

on a date other than the date of a meeting at which all directors are elected, he or she automatically is granted a non-statutory option to purchase the number of shares equal to (a) 2,500 multiplied by (b) the difference between 12 and the number of months since the last meeting at which directors were elected, vesting at a rate of 2,500 shares per month.

Each automatic grant under the 2002 Stock Incentive Plan has an exercise price per share equal to the fair market value per share of common stock on the grant date and has a maximum term of ten years, subject to earlier termination twelve months after the date of the optionee’s cessation of Board service for any reason. Each automatic option is immediately exercisable for all of the option shares. However, any shares purchased under such option are subject to repurchase by us, at the lower of the exercise price paid per share or the fair market value per share (determined at the time of repurchase), should the optionee cease Board service prior to vesting in those shares. The shares subject to each initial option grant and each annual option grant will immediately vest in full if certain changes in control or ownership occur or if the optionee dies or becomes disabled while serving as a director.

Under the automatic option grant program, Messrs. Pignatelli and d’Arbeloff and Dr. Anderton each received an automatic option grant on November 15, 2005 to purchase 30,000 shares of common stock at an exercise price of $5.81 per share.

Summary of Cash and Certain Other Compensation

The following table summarizes all compensation paid to persons who served as our chief executive officer during the last fiscal year, our executive officer whose served in that capacity at December 31, 2004 and whose total salary and bonus exceeded $100,000, and two other executive officers who no longer serve in that capacity at December 31, 2004 but whose total salary and bonus exceeded $100,000 (which we refer to collectively as the named executive officers), for services rendered in all capacities to us and our subsidiaries for the fiscal years ended December 31, 2004, 2003 and 2002. Perquisites and other personal benefits paid to the named executive officers are less than the minimum reporting threshold of $50,000 or 10% of the total annual salary plus bonus for the named executive officer, and such amounts paid, if any, are represented in the table by “$—.”

Employment Contracts, Termination of Employment and Change in Control Arrangements

The Compensation Committee of our Board of Directors has the authority to provide for accelerated vesting of the shares of our common stock subject to any outstanding options held by the chief executive officer or any other executive officer or any unvested share issuances actually held by such individual, in connection with certain changes in control of us or the subsequent termination of the officer’s employment following the change of control event. In addition, as described below, options held by our chief executive officer and chief financial officer accelerate upon a change of control.

Employment Agreement with Robert E. Grant

On October 26, 2004, we entered into an at-will Employment Agreement with Robert E. Grant, our newly appointed President and Chief Executive Officer, which superseded his Employment Agreement of August 2003. The agreement provides for an annual base salary of $275,000 and, beginning in calendar year 2005, an annual bonus of up to $175,000 (Mr. Grant’s bonus for calendar year 2004 was $78,000). Sixty percent of the annual bonus is based on the achievement of revenue targets and 40% is based on the achievement of net income targets. In connection with the annual bonus, Mr. Grant is eligible to receive up to $50,000 paid quarterly based upon the achievement of such revenue and net income targets. The remaining portion of the bonus (up to $125,000) was payable upon the completion and filing with the SEC of our Annual Report on Form 10-K with the SEC for the previous reporting year. Mr. Grant is guaranteed a minimum bonus of $50,000. The agreement also provides for a stock option grant to purchase 400,000 shares of common stock at an exercise price of $5.98 per share, with pro rata vesting quarterly over three years at the rate of 33,333 shares per quarter, with the first quarter ending on December 31, 2004. Mr. Grant will also be eligible to receive stock options with respect to 100,000 shares annually beginning on the third anniversary of the effective date of the agreement. Mr. Grant is entitled to four weeks paid vacation, we pay the medical and dental plan premiums for him and his immediate family and we reimburse him for out-of-pocket costs, fees, charges or expenses in connection with the medical and dental plans, which reimbursement shall not exceed $3,000 without the prior written consent of the Board of Directors. We have agreed to assume or reimburse Mr. Grant the costs associated with the lease of his vehicle.

In the event we terminate Mr. Grant’s employment without cause or Mr. Grant terminates his employment for good reason, he will receive severance equal to six times the base monthly salary he was receiving immediately prior to the date of termination or resignation, we will pay his COBRA premiums for the six-month period following termination or resignation, he will be entitled to receive the pro-rated portion of any performance bonus to which he would otherwise be entitled and his stock options will continue to vest through the end of the quarter in which such termination or resignation becomes effective. Mr. Grant will have one year from the effective date of such termination or resignation to exercise the vested portion of his stock options.

In the event of Mr. Grant’s death while employed by us and during the term of the agreement, Mr. Grant’s estate will receive a lump sum payment of an amount equal to six months of his then effective base salary, subject to offset from insurance benefit payments, and all stock options that would be vested at the end of the quarter in which the death occurred will be vested and immediately exercisable. His estate will have one year from the effective date of such death to exercise the vested portion of Mr. Grant’s stock options.

If Mr. Grant’s employment is terminated by us due to mental or physical disability, Mr. Grant will continue to receive his base salary for six months and all stock options that would be vested at the end of the quarter in which the termination occurred will be vested and immediately exercisable. Mr. Grant will have one year from the effective date of the termination to exercise the vested portion of his stock options.

Upon a change of control of us, which includes a change in a majority of the Board composition within a period of 60 consecutive days or the acquisition of us by a third party of greater than 50% of our outstanding shares, all options held by Mr. Grant will fully vest and become immediately exercisable.

We have agreed to indemnify Mr. Grant, to the maximum extent permitted under Delaware law, against any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, threatened or initiated against him by reason of the fact that he was serving as an officer, director, employee or agent of ours or was serving at our request as an officer, director, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

Unless earlier terminated, the terms of the Employment Agreement will end on October 23, 2007, provided that, unless and until a new written agreement is entered into, the employment relationship under the agreement

will continue on a calendar quarter to calendar quarter basis with the same remuneration and compensation as shall apply during the final year of the agreement term.

Employment Agreement with Richard L. Harrison

On December 12, 2005, we entered into an at-will Employment Agreement with Richard L. Harrison, our newly appointed Executive Vice President and Chief Financial Officer. Mr. Harrison’s employment commenced on December 12, 2005 and he was appointed Executive Vice President and Chief Financial Officer the same day. The agreement provides for an annual base salary of $230,000 and an annual performance bonus of up to $100,000. The agreement also provides for a stock option grant to purchase 250,000 shares of common stock at an exercise price of $7.20 per share, with one-third of the options becoming vested on the first anniversary of the effective date and one-eighth vesting quarterly thereafter. The exercise price of such stock option is the fair market value of our common stock on the date of grant, December 12, 2005. Mr. Harrison is entitled to four weeks paid vacation and a $1,000 monthly car allowance. We pay the medical and dental plan premiums for Mr. Harrison and his immediate family and we reimburse him for out-of-pocket costs, fees, charges or expenses in connection with the medical and dental plans, which reimbursement shall not exceed $3,000 without the prior written consent of the Board of Directors.

In the event we terminate Mr. Harrison’s employment without cause or Mr. Harrison terminates his employment for good reason, he will continue to receive his base salary from us for six months following his date of termination or resignation and he will be entitled to receive the pro-rated portion of any performance bonus to which he would otherwise be entitled.

In the event of Mr. Harrison’s death while employed by us and during the term of the agreement, Mr. Harrison’s estate will receive his base salary from us for six months following his date of death.

Upon a change of control of us, which includes the sale, transfer or other disposition of all or substantially all of our assets in complete liquidation or dissolution or the acquisition of us by a third party of greater than 50% of our outstanding shares, all options held by Mr. Harrison will fully vest and become immediately exercisable.

Employment Agreement with Jeffrey W. Jones

On December 29, 2005, we entered a new employment agreement, or the Employment Agreement, with Jeffrey W. Jones, Vice Chairman of the Board and Chief Technology Officer. The Employment Agreement replaces an earlier employment agreement dated December 12, 2003 between us and Mr. Jones which expired by its terms on December 31, 2005.

Under the terms of the Employment Agreement, Mr. Jones’ employment is at will and not for a specific term, and may be terminated at any time by either us or him, with or without cause, as defined in the Employment Agreement. If Mr. Jones’ employment is terminated other than for cause or he resigns for good reason, Mr. Jones will be entitled to receive severance pay in an amount equal to one year of annual base salary.

Under the terms of the Employment Agreement, Mr. Jones receives a base annual salary of not less than $250,000. In addition, Mr. Jones is entitled to earn an annual performance bonus of $100,000, based on the achievement of certain criteria established by our Board of Directors, of which $42,000 is guaranteed. Mr. Jones’ base salary is being reduced from $275,000 to $250,000 and his annual performance bonus is being reduced from $160,000 to $100,000. Mr. Jones is entitled to receive a housing allowance of $3,500 per month for expenses incurred in maintaining a residence in California in connection with his employment by us. The housing allowance will be deducted from any bonus he is entitled to receive. Mr. Jones is also entitled to receive an allowance for an automobile and related expenses, four weeks paid vacation per year, reimbursement of reasonable business expenses and other executive benefits.

Employment Agreement with James Haefner

On January 24, 2005, we entered into an at-will Employment Agreement with James Haefner, as our Executive Vice President of Sales. Mr. Haefner’s employment commenced January 24, 2005. The agreement provides for an annual base salary of $200,000, a signing bonus of $4,000 and, beginning in calendar year 2005, an annual performance bonus of $100,000 at a rate of $25,000 per quarter based on sales and other performance targets and an over-performance bonus of $50,000 based on sales over certain performance targets as determined by our Board of Directors. The agreement also provides for a stock option grant to purchase (i) 80,000 shares of our common stock at an exercise price of $9.77 per share upon the commencement of Mr. Haefner’s employment, with one-third of the options becoming vested on the first anniversary of the date of grant and the remaining two-thirds becoming vested quarterly for two years thereafter, and (ii) 30,000 to 40,000 shares of our common stock at an exercise price equal to the fair market value of our common stock on the date of grant, depending on the price of our common stock following the Annual Meeting of the Stockholders in 2005, with the same vesting schedule as set forth above for Mr. Haefner’s initial grant. In addition, Mr. Haefner is eligible to participate in all of the employee benefits and benefit plans that we generally make available to our full-time employees.

In the event that we are acquired by or merged with another entity, the new entity will have the option of (i) offering Mr. Haefner a one-year contract on similar or better terms as set forth above or (ii) paying Mr. Haefner severance for six months in an amount equal to the total compensation received by Mr. Haefner for the prior six months. In the event that Mr. Haefner’s employment is terminated without cause, Mr. Haefner will be entitled to receive severance in an amount equal to four months of his base salary.

Employment Agreement with Keith G. Bateman

In January 1999, we entered into an employment agreement with Keith G. Bateman, then Vice President of Global Sales. Mr. Bateman was subsequently named Executive Vice President in 2002 and Executive Vice President, Marketing in January 2005. Mr. Bateman’s base salary was $175,000 for 2004. Under the terms of this agreement, if we are acquired or merged, the surviving entity either must offer Mr. Bateman a one-year employment agreement with at least equivalent compensation terms as he receives from us or must pay Mr. Bateman severance in an amount equal to his total compensation during the previous nine months, including base salary, commissions and bonus. Except for the above-described provision relating to an acquisition or merger, the agreement is terminable at any time by us or Mr. Bateman.

Compensation Committee Interlocks and Insider Participation

During 2004, the Compensation Committee consisted of Messrs. Pignatelli and d’Arbeloff and Dr. Anderton. No member of the Compensation Committee was an officer or employee of ours at any time during the 2004 fiscal year or at any other time. The Board of Directors as a whole, including our Chief Executive Officer, made all compensation decisions with respect to our executive officers during 2004. No current executive officer has ever served as a member of the board of directors or compensation committee of any other entity that has or has had one or more executive officers serving as a member of our Board of Directors or Compensation Committee.

RELATED PARTY TRANSACTIONS

Transactions with Management and Others

See above discussion under “Employment Contracts, Termination of Employment and Change in Control Arrangements” for a discussion of the employment agreements we have with Messrs. Grant, Haefner, Harrison, Jones and Bateman. In addition to indemnification provisions contained in certain of our employment agreements, our officers and directors are indemnified under Delaware General Corporation Law and our bylaws to the fullest extent permitted under Delaware law.

Jones, George V. d’Arbeloff, Dr. Robert Anderton, Robert E. Grant, Keith G. Bateman and James M. Haefner. In December 2005, we entered into a similar Indemnification Agreement with Richard L. Harrison. The form of the indemnification agreement was approved by our stockholders at our annual meeting of stockholders held on November 15, 2005. Pursuant to the terms of the Indemnification Agreements we will indemnify such directors and officers to the fullest extent permitted under Delaware law and our Certificate of Incorporation. The Indemnification Agreements provide that, among other things, (i) we will indemnify such directors and officers if and wherever they are made party to a proceeding or are threatened to be made a party to a proceeding, (ii) we will advance all reasonable expenses incurred, whether prior to or after a final determination of a proceeding and (iii) we will use all reasonable efforts to provide and maintain directors’ and officers’ liability insurance policies. In addition, our executive officers and directors are indemnified under Delaware General Corporation Law and our bylaws to the fullest extent permitted under Delaware law.

Since January 1, 2004, there has not been any transaction or series of similar transactions to which we were or are a party in which the amount involved exceeded or exceeds $60,000 and in which any director, executive officer, holder of more than five percent of any class of our voting securities, or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest.

Equity Incentive Plans

We maintain various equity incentive plans designed to attract and retain the services of individuals essential to our long term growth and success. These plans consist of the 1990 Stock Option Plan, 1993 Stock Option Plan and 2002 Stock Incentive Plan, as amended (the “2002 Plan”). The 1990 Stock Option Plan and 1993 Stock Option Plan have terminated pursuant to their terms. No new option grants may be issued under the 1990 Stock Option Plan or 1993 Stock Option Plan.

The following table provides information as of December 31, 2004 and September 15, 2005 with respect to the shares of our common stock that may be issued under our existing equity compensation plans.

(1)	Consists solely of the 2002 Stock Incentive Plan and 1993 Stock Option Plan.

(2)	Consists solely of the 1990 Stock Option Plan. Options granted in 1995 totaling 50,000 shares were held by one of our named executive officers at December 31, 2004, under the 1990 Stock Option Plan.

Our 1990 Stock Option Plan (the “1990 Plan”) was implemented by the Board on December 15, 1990. The 1990 Plan is a non-stockholder-approved plan under which options were authorized to be granted to directors, officers or employees of ours. The Board authorized 150,000 shares of common stock for issuance under the 1990 Plan. Options under this plan were granted with an exercise price per share equal to the fair market value per share of common stock on the grant date and vested in installments during the optionee’s period of service with us. The plan administrator (either the Board or a Board committee) may cause options to vest on an accelerated basis in the event we are acquired and those options are not assumed or replaced by the acquiring entity. Each option has a maximum term (not to exceed 10 years) set by the plan administrator at the time of grant, subject to earlier termination following the optionee’s termination.

Our 2002 Plan was approved by our stockholders on May 23, 2002. The 2002 Plan originally reserved 3,000,000 shares of common stock for issuance as stock awards or upon exercise of options granted pursuant to the 2002 Plan. The addition of 1,000,000 shares issuable under the 2002 Plan was approved by stockholders on May 26, 2004. Options granted under the 2002 Plan will have an exercise price per share determined by the Board, which generally is not less than one hundred percent of the fair market value of our stock on the grant date.

Through our equity incentive plans, our officers and other employees, non-employee directors and independent contractors have the opportunity to acquire an equity interest in our company. Our Board and the Compensation Committee of the Board have the authority to administer discretionary option grants and stock issuance programs for executive officers, employees and consultants and non-employee directors. In addition, the Board or Compensation Committee may appoint a secondary committee comprised of one or more directors to have authority to make equity grants to persons other than executive officers and non-employee directors. The Board or such committees have discretion to determine which individuals are eligible to receive equity grants, when grants are made, the number of shares subject to each grant, the status of any option as either an incentive stock option or a non-statutory option under the Federal tax laws, the vesting schedule (if any) for the grant and the maximum term for which any option is to remain outstanding. In addition, the 2002 Plan provides for an automatic stock option grant program for our non-employee directors, and neither the Board nor the Compensation Committee can exercise discretion over this program.

No option granted under our equity compensation plans has a term in excess of ten years, and the shares subject to options generally vest in one or more installments over a specified period of service. However, one or more options may be structured so that they will be immediately exercisable for any or all of the option shares,

and the shares purchased may be subject to repurchase by us in certain circumstances. Options may also be subject to acceleration of vesting in the event of an acquisition of us, where the Board deems it appropriate to provide such a provision. Shares may be issued under the stock issuance program generally at a price per share not less than their fair market value, or may be issued as a bonus for past services. The shares issued may be fully vested or may vest upon the completion of a designated service period or the attainment of pre-established performance goals. Shares issued may also be subject to acceleration of vesting in the event of an acquisition of us, where the Board deems it appropriate to provide such a provision.

SELLING STOCKHOLDERS

The following table sets forth the names of the selling stockholders, the number of shares being registered for sale as of the date of this prospectus and the number of shares of common stock known by us to be beneficially owned by the selling stockholders as of November 29, 2005. The shares offered by this prospectus may be offered from time to time by the selling stockholders. We are unable to determine the exact number of shares that actually will be sold because the selling stockholders may sell all or some of the shares. The following table assumes that the selling stockholders will sell all of the shares being offered for their account by this prospectus, and will not own any shares of our common stock after the offering. The selling stockholders are not making any representation that any shares covered by this prospectus will or will not be offered for sale. The selling stockholders reserve the right to accept or reject, in whole or in part, any proposed sale of shares.

The information provided above is based upon information provided by the selling stockholders and public documents filed with the SEC and is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated in the discussion immediately below, we are not aware of any material relationship between us and the selling stockholders within the past three years other than as a result of the ownership of the selling stockholders’ shares described below.

against other unrelated third parties. Pursuant to the litigation settlement agreement between Diodem and us, such escrowed shares shall be released upon the earlier of (i) there being at least one valid claim resulting from such patent litigation among Diodem and the other unrelated third parties or (ii) July 14, 2006. We expect that the conditions for the release of these escrowed shares will be met. The common stock issued, the escrow shares and the warrant shares have certain registration rights and are being registered for resale by the registration statement of which this prospectus forms a part. The total consideration was estimated to have a value of approximately $7.0 million, excluding the value of the shares held in escrow which are contingent in nature, but including the value of the patents acquired in January 2005. As of December 31, 2004, we accrued approximately $6.4 million for the settlement of the existing litigation. In January 2005, we recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents held by us are licensed to a third party. In order to secure performance by us of these financial obligations, the parties entered into an intellectual property security agreement, pursuant to which, subject to the rights of existing creditors and the rights of any future creditors to the extent provided in the agreement, we granted Diodem a security interest in all of their right, title and interest in the royalty patents. In addition, we will be required, by January, 2006, to provide Diodem a ten-year letter of credit from a bank in the amount of $500,000 as additional security.

This prospectus also covers any additional shares of stock which become issuable in connection with the shares being registered by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the receipt of consideration which results in an increase in the number of our outstanding shares of common stock.

The Series B Preferred Stock is issuable in connection with our “poison pill” stockholder Rights Plan, which the Board of Directors adopted on December 18, 1998, and which is discussed below. The Series B Preferred Stock ranks senior to our common stock with respect to payment of distributions on liquidation, dissolution or winding up and with respect to the payment of dividends but will rank junior to all series of preferred stock with respect to dividends and the distribution of assets. The section below describing the Rights Plan that the Board of Directors adopted contains additional information on the rights to which a holder of Series B Preferred Stock will be entitled.

The Board of Directors may issue up to 500,000 shares of the remaining authorized preferred stock in one or more series, establish the number of shares to be included in any of these series and fix the designations, powers, preferences and rights of the shares of each of these series and any qualifications, limitations or restrictions thereof, including dividend rights and preferences over dividends on the common stock, conversion rights, voting rights, redemption rights, the terms of any sinking fund therefor and rights upon liquidation.

Options

As of September 15, 2005, we had outstanding options to purchase up to an aggregate of 3,682,000 shares of common stock with a weighted average exercise price of $6.09, of which 2,648,000 were then exercisable. We have 142,856 additional shares of common stock reserved for future grant or issuance under our equity incentive compensation plans.

Warrants

In connection with our purchase of certain patents and patent applications from Diodem, on January 24, 2005, we issued a warrant to Diodem to purchase 81,037 shares of our common stock. The warrant is exercisable for the period beginning on January 24, 2005 and ending on January 24, 2010 and it is exercisable at a price of $11.06 per share. The exercise price and the number of shares purchasable are subject to adjustment under certain circumstances such as (i) the reclassification of our common shares, (ii) the split, subdivision or combination of our common shares, or (iii) the issuance of dividends in stock or other securities or property. Diodem subsequently assigned the 361,664 shares of common stock not held in escrow and the warrant to purchase 81,037 shares of common stock, to and among the following four parties: (i) Dovel & Luner, LLP; (ii) Lares Research; (iii) Colette Cozean; and (iv) Patrick J. Day.

Certain Provisions in Our Certificate and Bylaws

Our Bylaws provide that special meetings of the stockholders may be called for any purpose, unless otherwise prescribed by statute or by the Certificate of Incorporation, by the Board of Directors, the Chairman of the Board, the CEO or the President, and shall be called by the Board of Directors or the Secretary at the written request of a majority of the Board of Directors or of the stockholders holding a majority of the outstanding shares of capital stock. Written notice of a special meeting shall be given to each stockholder entitled to vote at such meeting not less than ten and no more than sixty days prior to the meeting.

Our Bylaws also provide that the stockholders may remove a director as provided by Delaware law. New directors may be elected by majority of the remaining directors then in office or by a plurality of votes cast at a special meeting of stockholders called in accordance with the Bylaws.

Our Certificate of Incorporation and Bylaws offer our directors certain protections to the extent permitted by Delaware law. Our directors are not liable to us or our stockholders for monetary damages for a breach of fiduciary duty, except in circumstances involving certain wrongful acts, such as the breach of a director’s duty of loyalty or acts or omissions which involve intentional misconduct or a knowing violation of law. Our Bylaws obligate us to indemnify our directors to the fullest extent permitted by the General Corporation Law of Delaware. We believe that these provisions will assist us in attracting and retaining qualified individuals to serve as directors.

Rights Plan

On December 18, 1998, our Board of Directors adopted a stockholder rights plan under which one preferred stock purchase right was distributed on January 11, 1999 with respect to each share of our common stock outstanding, and one right continues to be issued with each share of our common stock issued since that date (including the shares sold under this prospectus). The rights provide, among other things, that if any person becomes the beneficial owner of 15% or more of our common stock while the rights are outstanding, each right will be exercisable to purchase shares of common stock having a market value equal to two times the then current exercise price of a right (initially $30.00). The rights also provide that, if on or after the occurrence of such event and while the rights remain outstanding, (i) we are merged into any other corporation and we are not the surviving corporation, (ii) another entity is merged into us and all or part of our common stock is exchanged for securities of another entity, cash or other property, or (iii) 50% or more of our assets or earning power are sold, each right will be exercisable to purchase common stock of the acquiring corporation having a market value equal to two times the then current market price of such stock. The rights will expire on December 31, 2008, unless previously triggered, and are subject to redemption at $0.001 per right (as adjusted to reflect any stock split, stock dividend or similar transaction occurring after December 31, 1998) at any time prior to the first date upon which they become exercisable to purchase common shares.

Our rights plan is designed to discourage hostile takeovers by effectively allowing our stockholders (other than any hostile acquirer holding more than 15% of our common stock) to purchase additional shares of our common stock at a discount following the hostile acquisition of a large block of our outstanding common stock and by increasing the value of consideration to be received by stockholders in specified transactions, so long as the rights remain outstanding, following such an acquisition.

Delaware Business Combination Statute

Section 203 of the Delaware General Corporation Law provides that, subject to certain exceptions specified therein, an “interested stockholder” of a Delaware corporation shall not engage in any business combination, including mergers or consolidations or acquisitions of additional shares of the corporation, with the corporation for a three-year period following the date that such stockholder becomes an interested stockholder unless:

•

prior to such date, the Board of Directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

•

upon consummation of the transaction which resulted in the stockholder becoming an “interested stockholder,” the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding certain shares); or

•

on or subsequent to such date, the business combination is approved by the Board of Directors of the corporation and authorized at an annual or special meeting of stockholders by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

Except as otherwise specified in Section 203, an interested stockholder is defined to include (1) any person that is the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date of determination and (2) the affiliates and associates of any such person.

Under certain circumstances, Section 203 makes it more difficult for a person who would be an interested stockholder to effect various business combinations with a corporation for a three-year period. We have not elected to be exempt from the restrictions imposed under Section 203. The provisions of Section 203 may encourage persons interested in acquiring us to negotiate in advance with our Board, since the stockholder approval requirement would be avoided if a majority of the Directors then in office approves either the business combination or the transaction which results in any such person becoming an interested stockholder. Such provisions also may have the effect of preventing the consummation of transactions resulting in a change of control. It is possible that such provisions could make it more difficult to accomplish transactions which our stockholders may otherwise deem to be in their best interests.

Limitation of Liability and Indemnification Matters

Our Certificate of Incorporation, as amended, provides that our directors will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for (i) any breach of their duty of loyalty to us or our stockholders, (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the General Corporation Law of the State of Delaware (the “Delaware Law”), or (iv) any transaction from which the director derives an improper personal benefit.

Article X of our Amended and Restated Bylaws provides that we will indemnify any director or officer, or former director or officer, who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, to the fullest extent authorized by the Delaware Law, against all costs, charges, expenses, liabilities and losses (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered in connection with such action, suit or proceeding. We also will indemnify any such director or officer, or any such former director or officer, against expenses incurred in defending any such action, suit or proceeding in advance of its final disposition, provided that, if required by the Delaware Law, the payment of such expenses will be made only upon delivery to us of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified.

Article X of our Amended and Restated Bylaws further provides that in the event a director or officer has to bring suit against us for indemnification and is successful, we will pay such director’s or officer’s expenses of prosecuting such claim; that indemnification provided for by the Amended and Restated Bylaws shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; that we may purchase and maintain insurance on behalf of a director or officer against any expense, liability or loss, whether or not we would have the power to indemnify such director or officer against such expense, liability or loss under the Delaware Law; and that to the extent any director or officer is by reason of such position a witness in any action, suit or proceeding, we shall indemnify him or her against all costs and expenses actually and reasonably incurred by him or her in connection therewith.

Our employment agreement with our President and Chief Executive Officer, Robert E. Grant, provides that we will, to the maximum extent permitted under Delaware law, indemnify Mr. Grant against any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, threatened or initiated against Mr. Grant by reason of the fact that he was serving as an officer, director, employee or agent of Biolase or was serving at the request of Biolase as an officer, director, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

In July 2005, we entered into separate but similar indemnification agreements (the “Indemnification Agreements”) with the following directors and officers: Federico Pignatelli, Jeffrey W. Jones, George V. d’Arbeloff, Dr. Robert Anderton, Robert E. Grant, Keith G. Bateman and James M. Haefner. In December 2005, we entered into an Indemnification Agreement with Richard L. Harrison, our newly appointed Executive Vice President and Chief Financial Officer. The form of the indemnification agreement was approved by our stockholders at our annual meeting of stockholders held on November 15, 2005. Pursuant to the terms of the Indemnification Agreements we will indemnify such directors and officers to the fullest extent permitted under Delaware law and our Certificate of Incorporation. The Indemnification Agreements provide that, among other things, (i) we will indemnify such directors and officers if and wherever they are made party to a proceeding or are threatened to be made a party to a proceeding, (ii) we will advance all reasonable expenses incurred, whether prior to or after a final determination of a proceeding and (iii) we will use all reasonable efforts to provide and maintain directors’ and officers’ liability insurance policies.

Section 145 of the Delaware Law provides that a Delaware corporation has the power to indemnify its directors and officers in certain circumstances.

Subsection (a) of Section 145 of the Delaware Law empowers a corporation to indemnify any director or officer, or former director or officer, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding provided that such director or officer acted in good faith and in a manner such director or officer reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, provided that such director or officer had no reasonable cause to believe his or her conduct was unlawful.

Subsection (b) of Section 145 of the Delaware Law empowers a corporation to indemnify any director or officer, or former director or officer, who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit, provided that such director or officer acted in good faith and in a manner such director or officer reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such director or officer shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine that despite the adjudication of liability, but in view of all the circumstances of the case, such director or officer is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

Section 145 of the Delaware Law further provides that to the extent a director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and that the corporation shall have power to purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against him or her or incurred by him or her in any such capacity or arising out of his or her status as such whether or not the corporation would have the power to indemnify him or her against such liabilities under Section 145.

We maintain directors’ and officers’ liability insurance covering our directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

Transfer Agent and Registrar

The transfer agent for our common stock is U.S. Stock Transfer Corporation.

PLAN OF DISTRIBUTION

We are registering all 487,909 shares of common stock covered by this prospectus on behalf of the selling stockholders. We originally issued an aggregate of 487,909 shares of common stock and warrants to purchase common stock to the selling stockholder, Diodem, on or about January 24, 2005 pursuant to a Definitive Asset Purchase Agreement. Diodem subsequently assigned the 361,664 shares of common stock not held in escrow and the warrant to purchase 81,037 shares of common stock, to and among the following four parties: (i) Dovel & Luner, LLP; (ii) Lares Research; (iii) Colette Cozean; and (iv) Patrick J. Day. These shares may be offered for sale on the NASDAQ National Market. We will not receive any of the proceeds from sales of the shares by the selling stockholders.

The selling stockholders named in this prospectus, or pledgees, donees, transferees or other successors-in-interest selling shares received from the selling stockholders as a gift, partnership distribution or other non-sale related transfer after the date of this prospectus may sell these shares from time to time. The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. The selling stockholders are, however, subject to certain limitations in its agreement with us pursuant to which we issued the shares, which limits the number of shares the selling stockholders may sell per day in the open market. Sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and at terms then prevailing or at prices related to the then current market price or in negotiated transactions. The selling stockholders may effect such transactions by selling the shares to or through broker-dealers. The shares may be sold by one or more of, or a combination of, the following:

•

a block trade in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by such broker-dealer for its account under this prospectus;

•

an exchange distribution in accordance with the rules of such exchange;

•

ordinary brokerage transactions and transactions in which the broker solicits purchasers; or

•

privately negotiated transactions.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In effecting sales, broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in such resales.

The selling stockholders may enter into hedging transactions with broker-dealers in connection with distributions of the shares or otherwise. In such transactions, broker-dealers may engage in short sales of the shares in the course of hedging the positions they assume with the selling stockholders. The selling stockholders also may sell shares short and redeliver the shares to close out such short positions. The selling stockholders may enter into option or other transactions with broker-dealers which require the delivery to the broker-dealer of the shares. The broker-dealer may then resell or otherwise transfer such shares under this prospectus. The selling stockholders also may loan or pledge the shares to a broker-dealer. The broker-dealer may sell the shares so loaned, or upon a default the broker-dealer may sell the pledged shares under this prospectus.

Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from the selling stockholders. Broker-dealers or agents may also receive compensation from the purchasers of the shares for whom they act as agents or to whom they sell as principals, or both. Compensation as to a particular broker-dealer might be in excess of customary commissions and will be in amounts to be negotiated in connection with the sale. Broker-dealers or agents and any other participating broker-dealers or the selling stockholders may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act of 1933 in connection with sales of the shares. Accordingly, any such commission, discount or concession received by them and any profit on the resale of the shares purchased by them may be deemed to be underwriting

discounts or commissions under the Securities Act. Because the selling stockholders may be deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act, the selling stockholders will be subject to the prospectus delivery requirements of the Securities Act.

In addition, any securities covered by this prospectus which qualify for sale under Rule 144 promulgated under the Securities Act may be sold under Rule 144 rather than under this prospectus. The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their securities. There is no underwriter or coordinating broker acting in connection with the proposed sale of shares by the selling stockholders.

The shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Securities Exchange Act of 1934, as amended, any person engaged in the distribution of the shares may not engage in market-making activities with respect to our common stock during certain restricted periods. In addition, the selling stockholders will be subject to applicable provisions of the Securities Exchange Act and the associated rules and regulations under the Securities Exchange Act, including Regulation M, which provisions may limit the timing of purchases and sales of shares of our common stock by the selling stockholders. We will make copies of this prospectus available to the selling stockholders and have informed the selling stockholders of the need for delivery of copies of this prospectus to purchasers at or prior to the time of any sale of the shares.

We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act upon being notified by the selling stockholders that any material arrangement has been entered into with a broker-dealer for the sale of shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer. Such supplement will disclose:

•

the name of such selling stockholder and of the participating broker-dealer(s),

•

the number of shares involved,

•

the price at which such shares were sold,

•

the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable,

•

that such broker-dealer(s) did not conduct any investigation to verify the information set out in this prospectus, and

•

other facts material to the transaction.

We will bear all costs, expenses and fees in connection with the registration of the shares. The selling stockholders will bear all commissions and discounts, if any, attributable to their respective sales of the shares. The selling stockholders may agree to indemnify any broker-dealer or agent that participates in transactions involving sales of the shares against certain liabilities, including liabilities arising under the Securities Act.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

BIOLASE Technology, Inc.:

We have completed an integrated audit of BIOLASE Technology, Inc.’s 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated Financial Statements and Financial Statement Schedule

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of BIOLASE Technology, Inc. and its subsidiaries at December 31, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 3 to the accompanying consolidated financial statements, the Company has restated its consolidated financial statements for the years ended December 31, 2003 and 2002.

Internal Control Over Financial Reporting

Also, we have audited management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing under “Management’s Discussion and Analysis—Controls and Procedures,” that BIOLASE Technology, Inc. did not maintain effective internal control over financial reporting as of December 31, 2004, because (1) the Company did not maintain a sufficient complement of personnel with a level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with the Company’s financial reporting requirements, which contributed to the following individual material weaknesses: (a) the Company did not maintain effective controls over the accounting for taxes other than income taxes, (b) the Company did not maintain effective controls over the identification of events that would trigger the need for an impairment analysis for indefinite-lived and long-lived assets, (c) the Company did not maintain effective controls over revenue recognition, (d) the Company did not maintain effective controls over the valuation of its inventory, (e) the Company did not maintain effective controls over accounts payable, certain accrued liabilities and the related expense accounts, and (f) the Company did not maintain effective controls over the accounting for foreign currency translation adjustments, (2) the Company did not maintain effective controls over cash accounts and cash disbursements in Germany, (3) the Company did not maintain effective controls over the processing of transactions of its subsidiary in Germany performed by a third party, (4) the Company did not maintain effective controls over the restriction of access to financial application programs and data, and (5) the Company did not maintain an effective control environment based on criteria established in “Internal Control—Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective

F-2

internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weaknesses have been identified and included in management’s assessment.

As of December 31, 2004, the Company did not maintain a sufficient complement of personnel with an appropriate level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with the Company’s financial reporting requirements. Specifically, the Company had deficiencies in accounting staff with sufficient depth and skill in the application of U.S. generally accepted accounting principles to meet the objectives that should be expected of these roles. This material weakness contributed to the following individual material weaknesses as of December 31, 2004.

The Company did not maintain effective controls over the accounting for taxes other than income taxes. Specifically, the Company’s controls failed to: (i) identify the existence of a liability for penalties and interest on amounts collected from customers that were not timely remitted to the states or have not been remitted to the states, and (ii) account for the gain on the abatement of certain penalties and interest. In addition, the Company’s controls failed to prevent or detect erroneous value added tax refunds that were incorrectly recorded as a receivable. This control deficiency resulted in an understatement of the sales tax and value added tax liabilities and general and administrative expense, which also resulted in the restatement of the Company’s annual 2002 and 2003, and first, second and third quarter 2004 consolidated financial statements.

The Company did not maintain effective controls over the identification of events that would trigger the need for an impairment analysis for indefinite-lived and long-lived assets. Specifically, the Company’s controls were ineffective in their design and operation to timely identify and

F-3

evaluate the impact of a change in circumstances that resulted in the impairment of an acquired trade name. This control deficiency resulted in an adjustment to intangible assets and operating expenses in the Company’s fourth quarter 2004 consolidated financial statements.

The Company did not maintain effective controls over certain aspects of revenue recognition. Specifically, the Company did not have effective controls over: (i) revenue recognized on multiple element arrangements that included spares and consumables not shipped as of the balance sheet date, and (ii) the deferral of revenue on units that were not fully functional at the time revenue was recognized. This control deficiency resulted in premature revenue recognition and an adjustment to deferred revenue and revenue in 2003 and in each of four quarters of the 2004 consolidated financial statements.

The Company did not maintain effective controls over the valuation of its inventory. Specifically, the Company did not have effective controls to: (i) identify slow-moving and obsolete inventory, and (ii) ensure its inventory was properly recorded at historical cost. This control deficiency resulted in adjustments to inventory and costs of goods sold in the Company’s first and fourth quarter 2004 consolidated financial statements.

The Company did not maintain effective controls over accounts payable, certain accrued liabilities and the related expense accounts. Specifically, the Company did not have effective controls over the completeness, valuation and existence of accounts payable, accrued commissions and bonuses payable, and the related expense accounts. This control deficiency resulted in adjustments to the Company’s consolidated financial statements for each of the four quarters in 2004.

The Company did not maintain effective controls over the accounting for foreign currency translation. Specifically, the Company did not have effective controls over the use of appropriate exchange rates for consolidating the financial statements of its Germany operations. This control deficiency resulted in adjustments to the Company’s second, third and fourth quarter 2004 consolidated financial statements.

As of December 31, 2004, the Company did not maintain effective controls over its cash accounts and cash disbursements in Germany. Specifically, the Company did not: (i) maintain a proper segregation of duties over the approval and payment of vendor invoices at its operations in Germany (i.e., the same individual who had access to bank accounts also authorized purchases and approved cash disbursements, and certain vendor payments, although valid, were executed by unauthorized individuals), and (ii) have effective controls over the review of bank reconciliations and the completeness, accuracy and validity of cash transactions recorded in the general ledger. This control deficiency did not result in an adjustment to the Company’s consolidated financial statements. However, it could result in a misstatement to cash and other financial statement accounts that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

As of December 31, 2004, the Company did not maintain effective controls over the processing of transactions of its subsidiary in Germany performed by a third party. Specifically, the Company did not have effective controls over the completeness, valuation and existence of certain financial statement accounts in Germany, such as accounts payable, accrued expenses, and the related sales and marketing, and general and administrative expenses, that are maintained by a third party. This control deficiency did not result in an adjustment to the Company’s consolidated financial statements. However, this control deficiency could result in a misstatement to the aforementioned financial statement accounts that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

As of December 31, 2004, the Company did not maintain effective controls over the restriction of access to financial application programs and data. The Company did not have effective controls over access to application programs and the underlying financial data. Specifically, there were instances in

F-4

which certain financial accounting personnel had inappropriate access to financial application programs and data and the activities of these individuals were not subject to independent monitoring. This control deficiency did not result in an adjustment to the Company’s consolidated financial statements. However, this control deficiency could result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

As of December 31, 2004, the Company did not maintain an effective control environment based on criteria established in “Internal Control—Integrated Framework” issued by the COSO. The financial reporting organizational structure was not adequate to support the activities of the Company. Deficiencies, such as an insufficient complement of personnel with an appropriate level of accounting knowledge, experience and training in the application of U.S. generally accepted accounting principles have resulted in adjustments to the consolidated financial statements as discussed in Item 1 above. Item 1, together with the material weaknesses described in Items 2, 3, and 4 above indicate that the Company did not maintain an effective control environment as of December 31, 2004. These control deficiencies could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2004 consolidated financial statements, and our opinion regarding the effectiveness of the Company’s internal control over financial reporting does not affect our opinion on those consolidated financial statements.

In our opinion, management’s assessment that BIOLASE Technology, Inc. did not maintain effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by the COSO. Also, in our opinion, because of the effects of the material weaknesses described above on the achievement of the objectives of the control criteria, BIOLASE Technology, Inc. has not maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control—Integrated Framework issued by the COSO.

NOTE 1—BASIS OF PRESENTATION

The Company

BIOLASE Technology Inc., incorporated in Delaware in 1987, is a medical technology company operating in one business segment that designs, manufactures and markets advanced dental, cosmetic and surgical laser and related products.

Basis of Presentation

The consolidated financial statements include the accounts of BIOLASE Technology, Inc. and its wholly owned subsidiaries: Societe Endo Technic, which is inactive and which we intend to dissolve, BIOLASE Europe GmbH (“BIOLASE Europe”), a foreign subsidiary incorporated in Germany in December of 2001, and BL Acquisition Corp., a Delaware corporation in whose name we acquired certain assets. We have eliminated all material intercompany transactions and balances in the accompanying financial statements.

Use of Estimates

The preparation of these financial statements in conformity with generally accepted accounting principles in the United States of America (GAAP) requires us to make estimates and assumptions that affect amounts reported in the financial statements and the accompanying notes. Significant estimates in these financial statements include allowances on accounts receivable, inventory, deferred taxes, as well as estimates for accrued warranty expenses, the realizability of goodwill and indefinite-lived intangible assets, pro-forma effects of stock-based compensation and the provision or benefit for income taxes. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

We consider all highly liquid investments with original maturities of three months or less as cash equivalents. We invest excess cash primarily in money market funds. Cash equivalents are carried at cost, which approximates market.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We evaluate our allowance for doubtful accounts based upon our knowledge of customers and their compliance with credit terms. The evaluation process includes a review of customers’ accounts on a regular basis which incorporates input from sales, service and finance personnel. The review process evaluates all account balances with amounts outstanding 60 days and other specific amounts for which information obtained indicates that the balance may be uncollectible. The allowance for doubtful accounts is adjusted based on such evaluation, with a corresponding provision included in general and administrative expenses. Account balances are charged off against the allowance when we feel it is probable the receivable will not be recovered. We do not have any off-balance-sheet credit exposure related to our customers.

Inventory

We value inventory at the lower of cost (determined using the first-in, first-out method) or market. We periodically review our inventory for excess quantities and obsolescence. We evaluate quantities on hand, physical condition, and technical functionality as these characteristics may be impacted by anticipated customer demand for current products and new product introductions. The allowance is adjusted based on such evaluation, with a corresponding provision included in cost of revenue.

F-10

Property, Plant and Equipment

We state property, plant and equipment at acquisition cost less accumulated depreciation. Maintenance and repairs are expensed as incurred. Upon sale or disposition of assets, any gain or loss is included in the consolidated statements of operations.

The cost of property, plant and equipment is depreciated using the straight-line method over the following estimated useful lives of the respective assets, except for leasehold improvements, which are depreciated over the lesser of the estimated useful lives of the respective assets or the related lease terms.


Building		30 years
Leasehold improvements		3 to 5 years
Equipment and computers		5 years
Furniture and fixtures		5 years

We monitor events and changes in circumstances, which could indicate that the carrying balances of property, plant and equipment may exceed the undiscounted expected future cash flows from those assets including their eventual disposition. If such a condition were to exist, we will recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.

Depreciation expense for 2004, 2003 and 2002 was approximately $448,000, $247,000 and $222,000, respectively.

Patents, Trademarks and Trade Names

Costs incurred to acquire and defend patents, and costs incurred to acquire trademarks and trade names are capitalized. Costs related to the internal development of technologies that we ultimately patent are expensed as incurred. All amounts assigned to these patents, trademarks and trade names, except those determined to have an indefinite life, are amortized on a straight-line basis over their estimated useful lives.

Fair Value of Financial Instruments

Our financial instruments consist of cash, accounts receivable, accounts payable and other accrued expenses that approximate fair value because of the short maturity of these items. The fair value of any foreign currency forward contracts is estimated by obtaining quotes from banks. As of December 31, 2004 and 2003, we did not hold any foreign currency forward contracts.

Other Comprehensive (Loss) Income

Other comprehensive (loss) income encompasses the change in equity from transactions and other events and circumstances from non-owner sources and is included as a component of stockholders’ equity but is excluded from net (loss) income. Accumulated other comprehensive loss consists of the effects of foreign currency translation adjustments and unrealized gains or losses on marketable securities classified as available for sale.

Foreign Currency Translation

The functional currency for our German subsidiary is the Euro. The results of operations and cash flows are translated at average exchange rates during the period, and assets and liabilities are translated at end-of-period exchange rates. Translation gains or losses are shown as a component of accumulated other comprehensive (loss) income in stockholders’ equity. Gains and losses resulting from foreign currency transactions, which are denominated in a currency other than the entity’s functional currency, are included in the consolidated statement of operations.

F-11

Derivative Financial Instruments

Our derivative financial instruments, which consisted of forward contracts in Euros, were recorded at their fair value. Our foreign exchange forward contracts were not designated as hedges. Changes in the fair value of derivatives that do not qualify for hedge treatment are recognized currently in earnings.

During the year ended December 2002, we recognized a gain of $152,000 for the change in fair value of the foreign exchange forward contracts with notional amounts of $697,000 and a fair value of $849,000. In February 2003, the contracts expired and were not renewed, resulting in a cumulative realized gain on the contracts of $174,000. At December 31, 2004 and 2003, there were no outstanding foreign exchange forward contracts.

Revenue Recognition

We sell products domestically to customers through our direct sales force, and internationally through a direct sales force and through distributors. We recognize revenue in accordance with SEC Staff Accounting Bulletin No. 104 “Revenue Recognition” which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to our customer or services have been rendered; (3) the price is fixed or determinable; and (4) collectibility is reasonably assured.

Through August 2003, the terms of our purchase orders for products sold domestically required payment in full before title was transferred. Accordingly, with all other criteria being met, we recognized revenue when payment was received. For products sold internationally through our direct sales force we recognized revenue when all other criteria were met and we completed installation, which was when the customer became obligated to pay. In August 2003, we modified the sales arrangements with our customers so that title transfers to the customer upon shipment for domestic sales, and there is an enforceable obligation to pay upon shipment for international direct sales. Beginning in August 2003, we have been recording revenue for domestic sales and international direct sales upon shipment. As a result, during 2003 we recorded $19.9 million in revenue before the modification to our sales arrangements and $21.8 million (restated) in revenue after the modification to our sales arrangements. We recognize revenue for products sold through our distributors internationally when the product is delivered. Revenue unaffected by the changes in our customer agreements with distributors was $7.2 million for the year ended December 31, 2003.

We adopted EITF 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables,” on July 1, 2003, which requires us to evaluate whether the separate deliverables in our arrangements can be unbundled. We determined that the sales of our Waterlase system include separate deliverables consisting of the product, disposables used with the Waterlase, installation and training. For these sales, we apply the residual value method, which requires us to allocate the total arrangement consideration less the fair value of the undelivered elements to the delivered elements. We determined that the sales of our Diode system include separate deliverables consisting of the product, disposables and training. For these sales, we apply the relative fair value method, which requires us to allocate the total arrangement consideration to the relative fair value of each element. Included in deferred revenue as of December 31, 2004 and 2003 is $1,871,000 and $887,000 (restated), respectively of deferred revenue attributable to undelivered elements, which primarily consists of training, installation and consumables.

Extended warranty contracts, which are sold to our non-distributor customers, are recorded as revenue on a straight-line basis over the period of the contracts, which is one year. Included in deferred revenue as of December 31, 2004 and 2003 is $597,000 and $342,000 for our extended warranty contracts, respectively.

F-12

We recognize revenue for royalties under licensing agreements for our patented technology when the product using our technology is sold. We estimate and recognize the amount sold based on historical performance and current knowledge about the business operations of our licensees. Our estimates have been historically consistent with amounts reported by the licensees. Revenue from royalties was $540,000, $221,000, and $0 for the years ended December 31, 2004, 2003, and 2002, respectively.

Provision for Warranty Expense

Products sold directly to end users are under warranty against defects in material and workmanship for a period of one year. Products sold internationally to distributors are covered by a warranty on parts for up to fourteen months. We estimate warranty costs at the time of product shipment based on historical experience. Estimated warranty expenses are recorded as an accrued liability, with a corresponding provision to cost of revenue.

Changes in the product warranty accrual, and the expenses incurred under our initial and extended warranties, for the years ended December 31 were as follows:


Warranty accrual, December 31, 2001	$	561,000
Warranty expenditures		(1,149,000	)
Provision for estimated warranty		1,213,000

Warranty accrual, December 31, 2002		625,000
Warranty expenditures		(1,078,000	)
Provision for estimated warranty		1,180,000

Warranty accrual, December 31, 2003		727,000
Warranty expenditures		(2,264,000	)
Provision for estimated warranty		2,448,000

Warranty accrual, December 31, 2004	$	911,000

Shipping and Handling Costs and Revenues

All shipping and handling costs are expensed as incurred and are recorded as a component of cost of revenue. Charges to our customers for shipping and handling are included as a component of revenue.

Advertising Costs

All advertising costs are expensed as incurred. Advertising costs incurred for the years ended December 31, 2004, 2003 and 2002, were approximately $1,578,000, $1,082,000 and $939,000, respectively.

General and Administrative

General and administrative expenses consist of salaries and benefits of administrative personnel as well as insurance, professional and regulatory fees, provisions for doubtful accounts, penalties and interest related to sales tax on amounts collected from customers but not timely remitted to the states, and subsequent gain for the amount of the liability relieved by the state. During the years ended December 31, 2004, 2003 and 2002, we recorded penalties and interest of $131,000, $263,000 and $191,000, respectively. During the years ended December 31, 2004 and 2003, we recognized gains of $372,000 and $17,000, respectively, related to the abatement of penalties and interest in certain states. No penalties or interest were abated during the year ended December 31, 2002.

F-13

Engineering and Development

Engineering and development expenses consist of engineering personnel salaries and benefits, prototype supplies, contract services and consulting fees related to product development. Engineering and development costs are expensed as incurred.

Income Taxes

Differences between accounting for financial statement purposes and accounting for tax return purposes are stated as deferred tax assets or deferred tax liabilities in the accompanying consolidated financial statements. The provision for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities. We establish a valuation allowance when it is more likely than not that the deferred tax assets are not realizable.

Stock-Based Compensation

We measure compensation expense for stock-based employee compensation plans using the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25. As the exercise price of all options granted under these plans was equal to the fair market value of the underlying common stock on the grant date, no stock-based employee compensation cost is recognized in the consolidated statements of operations.

On December 31, 2002, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 148, “Accounting for Stock Based Compensation Transition and Disclosure,” which amends SFAS No. 123. SFAS No. 148 requires more prominent and more frequent disclosures about the effects of stock-based compensation by presenting pro forma net income (loss), pro forma net income (loss) per share and other disclosures concerning our stock-based compensation plan.

The following table illustrates the effect on net (loss) income and net (loss) income per share if we had applied the fair value recognition provisions of SFAS No. 123 to options granted under our stock-based employee compensation plans:


	Years Ended December 31,
	2004			2003 Restated		2002 Restated
Reported net (loss) income	$	(23,214,000	)	$	19,049,000	$	1,051,000
Total stock-based employee compensation expense determined under the fair value based method for all awards, net of related tax effects		(5,334,000	)		27,000		(1,247,000	)

Pro forma net (loss) income	$	(28,548,000	)	$	19,076,000	$	(196,000	)


The pro forma net (loss) income has been revised to reflect the restatement of our consolidated financial statements described in Note 3 and to reflect revisions in the calculation to stock-based employee compensation expense.

Basic net (loss) income per share:
Reported	$	(1.00	)	$	0.91	$	0.05
Pro forma	$	(1.23	)	$	0.91	$	(0.01	)
Diluted net (loss) income per share:
Reported	$	(1.00	)	$	0.84	$	0.05
Pro forma	$	(1.23	)	$	0.85	$	(0.01	)

F-14

The pro forma amounts were estimated using the Black-Scholes option-pricing model with the following assumptions:


	2004			2003			2002
Expected term (years)		3.62			3.50			3.50
Volatility		65	%		80	%		84	%
Annual dividend per share	$	0.06		$	0.00		$	0.00
Risk-free interest rate		3.22	%		2.23	%		3.11	%
Weighted-average fair value	$	4.53		$	6.92		$	2.89

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Our options have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the fair value estimate.

Net (Loss) Income Per Share—Basic and Diluted

Basic net (loss) income per share is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. In computing diluted income per share, the weighted average number of shares outstanding is adjusted to reflect the effect of potentially dilutive securities.

Stock options totaling 4,070,000, 730,000 (restated) and 803,000 (restated) were not included in the diluted (loss) income per share amounts for the years ended December 31, 2004, 2003 and 2002, respectively, as their effect would have been anti-dilutive.


	Years Ended December 31,
	2004	2003 Restated	2002 Restated
Weighted average shares outstanding—basic	23,181,000	20,993,000	19,929,000
Dilutive effect of stock options and warrants	—	1,696,000	1,420,000

Weighted average shares outstanding—diluted	23,181,000	22,689,000	21,349,000

Outstanding options excluded as impact would be anti-dilutive	4,070,000	730,000	803,000

The dilutive effect of stock options and warrants have been decreased by 289,000 and increased by 46,000 for 2003 and 2002, respectively, to reflect a revision in the calculation.

New Accounting Pronouncements

In March 2004, the FASB approved the consensus reached on the Emerging Issues Task Force (EITF) Issue No. 03-1, “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.” The Issue’s objective is to provide guidance for identifying other-than-temporarily impaired investments. EITF 03-1 also provides new disclosure requirements for investments that are deemed to be temporarily impaired. The accounting provisions of EITF 03-1 are effective for all reporting periods beginning after June 15, 2004, while the disclosure requirements are effective for annual periods ending after June 15, 2004. In September 2004, the FASB issued a FASB Staff Position (FSP) EITF 03-1-1 that delays the effective date of the measurement and recognition guidance in EITF 03-1 on certain impaired debt securities until further deliberations by the FASB. The adoption of this pronouncement did not impact our consolidated financial position, results of operations or cash flows.

F-15

In December 2004, the FASB issued SFAS No. 123R (revised 2004), “Share-Based Payment,” which revised SFAS No. 123, “Accounting for Stock-Based Compensation.” This statement supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.” The revised statement addresses the accounting for share-based payment transactions with employees and other third parties, eliminates the ability to account for share-based compensation transactions using APB 25 and requires that the compensation costs relating to such transactions be recognized in the consolidated statement of operations. The revised statement is effective as of the first annual period beginning after June 15, 2005. In accordance with the revised statement, we will be required to recognize the expense attributable to stock options granted or vested subsequent to December 31, 2005. We are currently evaluating the impact of this pronouncement on our consolidated financial position, results of operations and cash flows.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs,” which amends part of ARB 43, “Inventory Pricing,” concerning the treatment of certain types of inventory costs. The provisions of ARB No. 43 provided that certain inventory-related costs, such as double freight and re-handling might be “so abnormal” that they should be charged against current earnings rather than be included in the cost of inventory. As amended by SFAS No. 151, the “so-abnormal” criterion has been eliminated. Thus, all such (abnormal) costs are required to be treated as current-period charges under all circumstances. In addition, fixed production overhead should be allocated based on the normal capacity of the production facilities, with unallocated overhead charged to expense when incurred. SFAS 151 is required to be adopted for fiscal years beginning after June 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

In December 2004, the FASB issued FASB Staff Position No. FAS 109-1, or FAS 109-1, “Application of FASB Statement No. 109, ‘Accounting for Income Taxes,’ to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004.” The American Jobs Creation Act, or AJCA, introduces a special 9% tax deduction on qualified production activities. FAS 109-1 clarifies that this tax deduction should be accounted for as a special tax deduction in accordance with Statement 109. Pursuant to the AJCA, the Company will not be entitled to this special deduction in 2005, as the deduction is applied to taxable income after taking into account net operating loss carryforwards, and we have significant net operating loss carryforwards that will fully offset taxable income. We do not expect the adoption of this new tax provision to have a material impact on our consolidated financial position, results of operations or cash flows.

In December 2004, the FASB issued FASB Staff Position No. FAS 109-2, or FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creations Act of 2004.” The AJCA introduces a limited time 85% dividends received deduction on the repatriation of certain foreign earnings to a U.S. taxpayer (repatriation provision), provided certain criteria are met. FAS No. 109-2 provides accounting and disclosure guidance for the repatriation provision. To achieve the deduction, the repatriation must occur by the end of 2005. We have not completed our analysis and do not expect to be able to make a decision on the amount of such repatriations, if any, until the fourth quarter of 2005. Among other things, the decision will depend on the level of earnings outside the United States, the debt level between our U.S. and non-U.S. affiliates, and administrative guidance from the Internal Revenue Service.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets” (“SFAS 153”), which eliminates the exception from fair value measurement for nonmonetary exchanges of similar productive assets and replaces it with a general exception from fair value measurement for exchanges of nonmonetary assets that do not have commercial substance. SFAS 153 is required to be adopted in fiscal periods beginning after June 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

In June 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections—a replacement of APB No. 20 and FAS No. 3” (“SFAS 154”). SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements

F-16

specific to the newly adopted accounting principle. SFAS 154 also provides guidance for determining whether retrospective application of a change in accounting principle is impracticable and for reporting a change when retrospective application is impracticable. The correction of an error in previously issued financial statements is not an accounting change. However, the reporting of an error correction involves adjustments to previously issued financial statements similar to those generally applicable to reporting an accounting change retrospectively. Therefore, the reporting of a correction of an error by restating previously issued financial statements is also addressed by SFAS 154. SFAS 154 is required to be adopted in fiscal years beginning after December 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

NOTE 3—RESTATEMENT OF FINANCIAL STATEMENTS

On May 20, 2005, we announced the restatement of our consolidated financial statements for the years ended December 31, 2003 and 2002. The adjustments reflected in the consolidated financial statements included in this registration statement for the years ended December 31, 2003 and 2002 are restated to correct for the following errors:

Adjustments Impacting Net Income

Revenue

During 2003, we did not identify all revenue arrangements that contained a training element to be performed after product shipment. This resulted in us recognizing revenue before we had performed the related services and resulted in an overstatement of revenue in the period the product was shipped. As a result, we decreased revenue for the undelivered training that had not been performed during the year ended December 31, 2003. There were no adjustments required for the year ended December 31, 2002.

During 2003, we improperly recognized revenue on consumables that had not been shipped. As a result, we have reduced revenue and increased deferred revenue and subsequently recognized revenue when the consumables were shipped.

During 2003, we did not identify a Waterlase system that was not fully functional at the time of shipment which resulted in the overstatement of revenue and cost of revenue. As a result, we decreased revenue and cost of revenue in 2003 and recognized the revenue and cost of revenue in 2004 when the final part required for functionally was delivered.

Cost of Revenue

We had not stated the cost of raw materials purchased at actual cost during the year ended December 31, 2003; accordingly, we decreased cost of revenue. We also reduced cost of revenue for sales tax on warranty items.

General and Administrative Expense

Sales tax liability, related penalties and interest, and gains recognized on the abatement of certain penalties and interest.

We charged our customers sales tax on purchases, but were late in filing sales tax returns and remitting amounts collected to certain states from 1998 to 2004. Additionally, the sales tax liability we recorded was understated. In accordance with the applicable accounting rules we are required to accrue, as a liability, interest and penalties under the applicable statutes, on late filings for which payment of sales tax has not been made. We have restated the consolidated financial statements for the years ended December 31, 2003 and 2002 to accrue these penalties and interest as a liability and to adjust for the under accrual of sales tax expense. During the year

F-17

ended December 31, 2003, we reached agreements with certain states and were relieved from our liability to pay certain of the penalties and interest. Accordingly, we recognized a gain for the difference between the amount of penalties and interest that we had accrued as a liability and the amount we will pay to those states.

Value-added tax

We determined that certain refunds previously claimed on our value added tax (VAT) returns and refunds recorded as a reduction of our VAT liability would be disallowed due to the improper collection of VAT information required at the time of product shipment. As a result, we increased our operating expense to properly reflect our liability for these items for the years ended December 31, 2003 and 2002.

Employee compensation

During the year ended December 31, 2003, we over accrued payroll expense for general and administrative personnel.

Other

During 2002, we identified but did not originally record adjustments determined to be immaterial individually and in the aggregate.

Income Taxes

The provision for income taxes has been revised to reflect the impact of the adjustments listed above. For 2002, we recorded a full valuation allowance against our net deferred tax assets due to the uncertainty of their realization. For 2003, we increased our net deferred tax assets and income tax benefit for the increases in our net operating loss carryforwards for the adjustments, excluding the deferred tax liability that arises as a result of the amortization of goodwill and our indefinite-lived intangible asset that are deductible for tax purposes, which was $38,000 for the year ended December 31, 2003.

The net effect of these errors is to decrease revenue by $298,000 and $0, to increase cost of revenue by $3,000 and to decrease cost of revenue by $82,000, and to increase operating expenses by $226,000 and $529,000 for the years ended December 31, 2003 and 2002, respectively, from the amounts previously reported.

F-18

The following table is a reconciliation of net income as previously reported to amounts as restated for the periods indicated:

Net income per share (restated):
Basic	$	0.91		$	0.05

Diluted	$	0.84		$	0.05

We also corrected the errors for the understatement of sales tax, penalties and interest for periods prior to January 1, 2002 for a total of $34,000, which has been reflected as a reduction in the opening balances of stockholders’ equity as of December 31, 2001.

Adjustments Not Impacting Stockholders Equity or Net Income

As of December 31, 2003, we reclassified deferred charges on products shipped to prepaid expenses and other current assets, and customer deposits to accounts payable, since they were considered minor for presentation as separate balance sheet components. We also reclassified our value added tax receivable included in prepaid expenses and other current assets as a reduction to our value added tax payable included in accrued liabilities. In addition, we reclassified amounts from accrued liabilities to deferred revenue so that all deferred revenue items are included in the same balance sheet component.

For the year ended December 31, 2003, we corrected the classification of $11,000 in income tax expense. For the year ended December 31, 2002, there were no adjustments impacting the classification of amounts in the statements of operations.

NOTE 4—INVESTMENTS IN MARKETABLE SECURITIES

We account for our marketable securities in accordance with SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” Investments classified as “available for sale” are reported at fair value with unrealized gains (losses) recorded as a component of comprehensive loss until realized. In the event the fair value of an investment declines and is deemed to be other than temporary, we write down the carrying value of the investment to its fair value. Our investments are comprised of U.S. treasury debt securities, have been classified as available-for-sale, and have maturities greater than three months and less than one year. As of December 31, 2004, no securities were impaired. The following summarizes our investments as of December 31, 2004:


	Amortized Cost		Unrealized Gain/(Loss)			Fair Value
Short-term
U. S. Treasury debt securities	$	25,339,000	$	(13,000	)	$	25,326,000

Gross realized gains and losses for the year ended December 31, 2004 were $96,000 and $(5,000), respectively.

We reimburse our customers for their costs related to certain marketing programs for which we do not receive an identifiable benefit. We reduce the revenue recognized at the time of the original sale by the amount we are obligated to pay our customers. Amounts due to customers represent our obligation to reimburse our customers for these programs.

Included in the sales tax liability is $333,000 and $574,000 as of December 31, 2004 and 2003, respectively, of penalties and interest determined in accordance with the applicable state statutes for amounts collected from customers but not remitted to the state.

NOTE 6—INTANGIBLE ASSETS AND GOODWILL

In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets,” goodwill and other intangible assets with indefinite lives are no longer subject to amortization but are tested for impairment annually or whenever events or changes in circumstances indicate that the asset might be impaired. We conducted our annual impairment analysis of our goodwill and trade names as of June 30, 2004 and concluded there had not been an impairment. During the fourth quarter of 2004, we changed our strategy to focus our sales efforts on high-end laser products such as the new Waterlase MD product, which was first sold during the fourth quarter of 2004. This conclusion was due to the increased competition for relatively low-priced laser devices. As a result, the actual sales of Diolase Plus were below our original expectations and we expect this trend to continue. We estimated the fair value of the Diolase Plus trade name using our revised strategy and based on a relief from royalty approach using discounted cash flows from revised projected Diolase Plus revenue. The $747,000 excess of the carrying value over the asset’s estimated fair value has been recorded as a charge to operations during the year ended December 31, 2004.

Intangible assets with finite lives continue to be subject to amortization, and any impairment is determined in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” We believe no event has occurred that would trigger an impairment of these intangible assets. We recorded amortization expense for the years ended December 31, 2004, 2003 and 2002 of $248,000, $154,000 and

F-26

$24,000, respectively. Estimated intangible asset amortization expense (based on existing intangible assets) for the years ending December 31, 2005, 2006, 2007, 2008 and 2009 is $239,000, $230,000, $226,000, $217,000 and $117,000, respectively. Other intangible assets consist of an acquired customer list and a non-compete agreement.

The following table presents details of our intangible assets, related accumulated amortization and goodwill:

NOTE 7—ACQUISITION

On May 21, 2003 we acquired the American Dental Laser (“ADL”) product line from American Medical Technologies, Inc. (“AMT”) for approximately $5.8 million, in order to leverage our marketing, strengthen our portfolio of intellectual property and expand our product lines. The assets acquired included inventory, dental laser patents, customer lists, brand names and other intellectual property as well as laser products. No liabilities of AMT were assumed in the transaction. The consideration paid by us consisted of approximately $1.8 million cash, $215,000 in transaction costs directly attributable to the acquisition and 307,500 shares of common stock with a fair value of approximately $3.8 million. For purposes of computing the purchase price, the value of the common stock of $12.38 per share was determined by taking the average closing price of our common stock as quoted on NASDAQ between May 19, 2003 and May 23, 2003. The total purchase price has been allocated to the acquired tangible and intangible assets of ADL based on the fair values with the balance allocated to goodwill. The acquisition was accounted for as a purchase under SFAS No. 141, “Business Combinations.” The amount allocated to the intangible assets was determined using estimates of discounted cash flow for the patents, trademarks, trade name and non-competition agreement; and the cost approach was used to estimate the value of the customer list. The total intangible assets acquired include approximately $2.9 million for goodwill (which is deductible for tax purposes), $979,000 for trade names and trademarks, $1.2 million for patents, $432,000 for a customer list and $91,000 for a non-compete agreement. The patents are being amortized over ten years, the customer list over six years, and the non-compete agreement over four years. The trademarks and trade names were determined to have indefinite lives (see Note 6 regarding an impairment recognized in 2004 related to trade names.)

The total consideration consisted of the following:


Cash	$	1,825,000
Stock consideration (307,500 shares at $12.38 per share)		3,806,000
Acquisition costs		215,000

Total	$	5,846,000

The components of the purchase price and allocation are as follows:


Tangible assets acquired	$	246,000
Identifiable intangible assets acquired		2,674,000
Goodwill		2,926,000

Total	$	5,846,000

NOTE 8—BANK LINE OF CREDIT AND DEBT

In May 2003, we entered into a $5.0 million credit facility with a bank. The facility is for a term of one year, bears interest at LIBOR plus 2.25% and is secured by all of our assets. Under the terms of our credit line, we are subject to certain covenants, which include, among other things, covenants to maintain a minimum balance of cash (including investments in U.S. treasuries), a specified minimum tangible net worth and a specified ratio of current assets to current liabilities, and a covenant to maintain profitability. If we fail to satisfy these covenants and we fail to cure any breach of these covenants within a specified number of days after receipt of notice, the bank could accelerate the entire amount borrowed by us and cancel the line of credit. Our credit line had an outstanding balance of approximately $1.8 million as of December 31, 2003. In June 2004, this credit facility was extended to June 30, 2005 and increased to $10.0 million. In June 2005, this credit facility was extended to September 30, 2005. At December 31, 2004, there were no borrowings on this line of credit. We were not in compliance with the covenants to remain profitable on a quarterly basis at December 31, 2004 due to our operating loss for the three months ended September 30, 2004 and December 31, 2004. In February 2005, we obtained a waiver of this covenant as of December 31, 2004. In April 2005, we became non-compliant with our covenant relating to timely reporting and certification requirements for our consolidated financial statements due to the late filing of our Form 10-K. In July 2005, we obtained a waiver to this covenant which extended until July 21, 2005.

In November 2003 we financed $489,000 of insurance premiums payable in ten equal monthly installments of approximately $45,000 each, including a finance charge of 3.3%. In December 2003 we financed an additional $598,000 of insurance premiums payable in ten equal monthly installments of approximately $54,000 each, including a finance charge of 2.9%. At December 31, 2003 the balance of unpaid premiums that were financed was $888,000 which was paid in full during the year ended December 31, 2004.

The deferred tax benefit for the year ended December 31, 2003 does not include $2,209,000 (restated), for stock option deduction benefits recorded as a credit to additional paid-in capital. The tax provision for 2002 is included in general and administrative expense in the accompanying consolidated statement of operations.

The provision for income taxes differs from the amount that would result from applying the federal statutory rate as follows for the years ended December 31:


	2004		2003		2002
			Restated		Restated
Statutory regular federal income tax rate	(34.0	)%	34.0	%	34.0	%

Total deferred tax liabilities		(375,000	)		(486,000	)

Net deferred tax assets (liability)	$	(161,000	)	$	14,159,000

The valuation allowance decreased from $16.2 million as of December 31, 2002 to zero as of December 31, 2003.

For the year ended December 31, 2004, stock option exercises increased our deferred tax assets by $1.9 million. In future years, if the valuation allowance is reduced, the benefit related to the stock option deferred tax assets will be recorded in stockholders’ equity.

During the year ended December 31, 2003, we determined that it was more likely than not that our deferred tax assets, which consist primarily of net operating loss, or NOL, carryforwards, would be realized, resulting in an $11.9 million net deferred tax benefit. This deferred tax benefit does not include $2.2 million for stock option deduction benefits recorded as a credit to additional paid-in-capital. We considered factors such as our profitable operating history, three years of cumulative income and projections of continued profitability at that time in making this determination.

As of December 31, 2004, we had net operating loss carryforwards for federal and state purposes of approximately $39.0 million and $11.3 million, respectively, which will begin to expire in 2005. The utilization of NOL and credit carryforwards may be limited under the provisions of the Internal Revenue Code Section 382 and similar state provisions. Section 382 of the Internal Revenue Code of 1986 generally imposes an annual limitation on the amount of NOL carryforwards that may be used to offset taxable income where a corporation has undergone significant changes in stock ownership. During the year ended December 31, 2003, we completed an analysis to determine the potential applicability of any annual limitations imposed by Section 382. Based on

F-30

our analysis, we believe that as of December 31, 2004, we have for federal income tax purposes, approximately $39.0 million of NOL carryforwards. Of this amount, approximately $34.5 million is available to offset 2005 federal taxable income and the taxable income generated in future years. Additional NOL carryforwards will become available at the rate of approximately $1.0 million per year for the years 2005 through 2009. As of December 31, 2004, we had research and development credit carryforwards for federal and state purposes of approximately $558,000 and $250,000, respectively which will begin expiring in 2011 for federal purposes and carryforward indefinitely for state purposes. However, any future ownership change qualifying under Section 382 may limit our ability to use remaining NOL and credit carryforwards.

U.S. income taxes and foreign withholding taxes were not provided for undistributed earnings for our non-U.S. subsidiaries. We intend to reinvest these earnings indefinitely in operations outside the United States.

NOTE 10—COMMITMENTS AND CONTINGENCIES

Leases

In March 2001, we entered into a $2.2 million sale-leaseback transaction whereby we sold and leased back our manufacturing facility located in San Clemente, California. The result of the sale was a $316,000 gain, which was deferred and is being amortized over the five-year lease term. The related lease is being accounted for as an operating lease. In March 2004, we leased additional office and manufacturing space in San Clemente, California. We also lease certain office equipment and automobiles under operating lease arrangements.

Future minimum rental commitments under operating leases with non-cancellable terms greater than one year for each of the years ending December 31 are as follows:


2005	$	584,000
2006		141,000
2007		38,000
2008		6,000

Total future minimum lease obligations	$	769,000

Rent expense was $595,000, $355,000 (restated) and $250,000 for the years ended December 31, 2004, 2003 and 2002, respectively.

Litigation

In August 2004, we and certain of our officers were named as defendants in several putative shareholder class action lawsuits filed in the United States District Court for the Central District of California. The complaints purport to seek unspecified damages on behalf of an alleged class of persons who purchased our common stock between October 29, 2003 and July 16, 2004. The complaints allege that we and our officers violated federal securities laws by failing to disclose material information about the demand for our products and the fact that the Company would not achieve the alleged forecasted growth. The claimed misrepresentations include certain statements in our press releases and the registration statement we filed in connection with our public offering of stock in March 2004. In addition, three stockholders have filed derivative actions in the state court in California seeking recovery on behalf of BIOLASE, alleging, among other things, breach of fiduciary duties by those individual defendants and by the members of our Board of Directors.

We have not yet formally responded to any of the actions and no discovery has been conducted by any of the parties. However, based on the facts presently known, our management believes we have meritorious defenses to these actions and intends to vigorously defend them. As of December 31, 2004, no amounts have been recorded in the consolidated financial statements for these matters since management believes that it is not probable we have incurred a loss contingency.

F-31

We estimated the amount for the settlement of the existing litigation by determining the estimated fair value of the patent portfolio less the total consideration of $7.0 million. The estimated fair value of the patents was determined using a relief from royalty and a discounted cash flow methodology. The common stock issued was valued at the common stock fair market value on the closing date the agreement for a total of $3.5 million. We determined the fair value of the warrants, which totaled $443,000 using the Black-Scholes model with the following assumptions:


Term		5 years
Volatility		67	%
Annual dividend per share	$	0.00
Risk-free interest rate		3.73	%

The warrants and common stock were issued in January 2005.

In late 2004, we were notified by Refocus Group, Inc., or Refocus, that certain of our planned activities in the field of presbyopia may infringe one or more claims of a patent held by Refocus. In February 2005, we filed a lawsuit in the U.S. District Court for the Central District of California against Refocus in order to obtain declaratory relief that certain of our planned activities in the field of presbyopia will not infringe the claims of a patent held by Refocus and/or that the claims are invalid. These claims were dismissed by the court in July 2005 without prejudice on the basis that we do not have a product that has been commercialized and, therefore, Refocus’ alleged infringement claims are not ripe. As of December 31, 2004, no amounts have been recorded in the accompanying consolidated financial statements for this matter since management believes that it is not probable we have incurred a loss contingency.

From time to time, we are involved in other legal proceedings incidental to our business, but at this time we are not party to any other litigation that is material to our business.

Securities and Exchange Commission Inquiry

Following the restatement of our financial statements in September 2003, we received, in late October 2003, and subsequently in 2003 and 2004, informal requests from the Securities and Exchange Commission, or SEC, to voluntarily provide information relating to the restatement. We have provided information to the SEC and intend to continue to cooperate in responding to the inquiry. In accordance with its normal practice, the SEC has not advised us when its inquiry may be concluded, and we are unable to predict the outcome of this inquiry.

NOTE 11—STOCKHOLDERS’ EQUITY

Preferred Stock

The Board of Directors, without further stockholder authorization, may issue from time to time up to 1,000,000 shares of our preferred stock. Of the 1,000,000 shares of preferred stock, 500,000 shares are designated as Series B Junior Participating Cumulative Preferred Stock. None of the preferred stock is outstanding.

On December 18, 1998, our Board of Directors adopted a stockholder rights plan under which one preferred stock purchase right was distributed on January 11, 1999 with respect to each share of our common stock outstanding at the close of business on December 31, 1998. The rights provide, among other things, that in the event any person becomes the beneficial owner of 15% or more of our common stock while the rights are outstanding, each right will be exercisable to purchase shares of common stock having a market value equal to two times the then current exercise price of a right (initially $30.00). The rights also provide that, if on or after the occurrence of such event and while the rights remain outstanding, (i) we are merged into any other corporation and we are not the surviving corporation, (ii) another entity is merged into us and all or part of our common stock is exchanged for securities of another entity, cash or other property, or (iii) 50% or more of our assets or earning power are sold, each right will be exercisable to purchase common stock of the acquiring corporation having a market value equal to two times the then current market price of such stock. The rights will expire on December 31, 2008, unless previously triggered, and are subject to redemption at $0.001 per right (as adjusted to reflect any stock split, stock dividend or similar transaction occurring after December 31, 1998) at any time prior to the first date upon which they become exercisable to purchase common shares.

Common Stock Options

We have stock option plans that enable us to offer equity participation to employees, officers and directors as well as certain non-employees. At December 31, 2004, a total of 6,025,000 shares have been authorized for issuance, of which 1,727,450 shares have been issued for options which have been exercised, 4,069,312 shares have been reserved for options that are outstanding, 104,856 shares are available for the granting of additional options and 123,382 shares are no longer available for granting due to the termination of the 1990 and 1993 Stock Option Plans.

Stock options may be granted as incentive or nonqualified options; however, no incentive stock options have been granted to date. The exercise price of options equals the market price of the stock as of the date of grant. Options may vest over various periods but typically vest over three years. Options expire after ten years or within a specified time from termination of employment, if earlier.

In addition to the options granted under our stock option plans, we have issued options to certain non-employees through various agreements. Options with a weighted average exercise price of $12.00 expired in 2002, leaving 87,500 options with a weighted average exercise price of $9.71 outstanding and exercisable at December 31, 2002. During 2003, 75,000 of those options were exercised at an exercise price of $10.50 per share and 12,500 options with an exercise price of $5.00 expired.

Stock Purchase Warrants

In March 2000, we issued 1,250,000 shares of common stock and warrants exercisable for 625,000 shares of our common stock in a private placement. Warrants exercisable for an additional 63,000 shares of our common stock were issued in connection with the placement. Each warrant entitled the holder to purchase one share of common stock at an exercise price of $2.50 per share and was originally scheduled to expire on March 31, 2002, but was subsequently extended to June 30, 2003.

F-34

We also issued 20,000 shares of common stock in 2001, valued at $95,000 and 37,000 shares of common stock together with warrants exercisable for 100,000 shares of our common stock in 2000, valued at $115,000 in connection with the extension of our previous bank line of credit. The value of the stock and warrants issued for services was charged to expense as compensation for services. The value of the shares issued in December 2001 was charged to interest expense during 2002.

In 2002, we extended the expiration date for warrants exercisable for 522,000 shares of our common stock issued in connection with the March 2000 private placement from March 2002 to June of 2003. In 2002, we also extended the expiration date of warrants exercisable for 50,000 shares of our common stock previously issued in connection with our bank line of credit from December 2002 to June 2003. There were no warrants issued or outstanding at December 31, 2004 and 2003.

The following table summarizes warrant activity:

In March 2004, as a result of the completion of a public underwritten offering, we issued 2,500,000 shares of common stock at an offering price of $18.50 per share. Gross proceeds from the offering were $46,250,000, before deducting underwriting discount of $2,875,000. In connection with the offering, we incurred direct expenses of $1,505,000, which had been included in other assets and were reclassified as a reduction of additional paid-in capital after the closing of the offering.

In July 2004, our Board of Directors authorized a 1.25 million share repurchase program. In August 2004, our Board of Directors authorized the repurchase of an additional 750,000 shares of our common stock, increasing the total shares repurchase program to 2.0 million shares of our common stock. Pursuant to these authorizations, we may purchase shares from time to time in the open market or through privately negotiated transactions over the next 12 months. During the year ended December 31, 2004, we repurchased approximately 1,964,000 shares at an average price of $8.35 per share.

In July 2004, we announced a policy to pay a cash dividend of $0.01 per share every other month payable to the stockholders of record when declared by the Board of Directors. The dividend policy will remain in place for an indefinite period of time and may be changed at any time at the discretion of our Board of Directors. Dividends totaling $689,000 were declared and paid in 2004 to stockholders of record under this program.

NOTE 12—SEGMENT INFORMATION

We currently operate in a single operating segment. For the years ended December 31, 2004, 2003 and 2002, export sales were $11.5 million, $9.8 million, and $6.2 million, respectively. In 2004, sales in Europe, Middle East and Africa (EMEA) accounted for approximately 11% of our revenue for the year, and sales in Asia, Latin America and Pacific Rim countries accounted for approximately 8% of the revenue for the year. Sales in Asia, Pacific Rim countries and Australia accounted for approximately 9% of our revenue in 2003, while sales in EMEA accounted for 11% of our 2003 revenue. In 2002, sales in EMEA accounted for approximately 11% of revenue for the year, whereas sales in Asia and Pacific Rim countries accounted for approximately 12% of the

F-35

revenue. No single foreign country accounted for more than 10% of revenue for the years ended December 31, 2004, 2003 and 2002.

Long-lived assets located outside of the United States at BIOLASE Europe were $1,258,000 and $1,199,000 as of December 31, 2004 and 2003, respectively.

Revenue by geographic location based on the location of customers was as follows:


	Year Ended December 31,
	2004		2003 Restated		2002 Restated
Domestic	$	49,109,000	$	38,993,000	$	21,047,000
International		11,542,000		9,790,000		6,210,000

	$	60,651,000	$	48,783,000	$	27,257,000

NOTE 13—CONCENTRATIONS

Many of the dentists finance their purchases through third-party leasing companies. In these transactions, the leasing company is considered the purchaser. Approximately 28%, 34% and 36% of our revenue in 2004, 2003 and 2002 were generated from dentists who financed their purchase through one leasing company, National Technology Leasing Corporation (“NTL”). Other than these transactions, no distributor or customer accounted for more than 10% of consolidated net sales in 2004, 2003 and 2002.

Financial instruments that subject us to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. We maintain our cash accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit of $100,000 for each account. At December 31, 2004 we held short-term investments in U.S. treasury securities with a fair market value of $25,326,000.

Accounts receivable concentrations have resulted from sales to NTL and totaled $776,000 and $742,000, respectively, at December 31, 2004 and 2003. No single customer accounted for more than 10% of our accounts receivable at December 31, 2004, and one customer, the leasing company mentioned above, accounted for 8% and 13% at December 31, 2004 and 2003, respectively. At December 31, 2004 and 2003, the three largest distributor accounts receivables totaled approximately $957,000 and $556,000 or 10% and 10% of total accounts receivable, respectively.

We currently buy certain key components of our products from single suppliers. Although there are a limited number of manufacturers of these key components, management believes that other suppliers could provide similar key components on comparable terms. A change in suppliers, however, could cause a delay in manufacturing and a possible loss of sales, which would adversely affect operating results.

Our Waterlase system comprised 84%, 83% and 77% of our net revenue for the years ended December 31, 2004, 2003 and 2002, respectively. Our Diode system comprised 11%, 12% and 18% of our net revenue for the same periods.

In February 2005, the Board of Directors declared a regular cash dividend of $0.01 per share. The dividend was payable February 24, 2005 to shareholders of record on February 10, 2005, for a total payment of $229,000.

In March 2005, we acquired a license to use in the U.S. and international markets, patents in the fields of presbyopia and ophthalmology from SurgiLight, Inc. for total consideration of $2.0 million in cash of which $1.8 million was paid in the first quarter of 2005 and $200,000 remains outstanding.

In April 2005, we received a notification from The Nasdaq Stock Market concerning our failure to comply with the requirement for continued listing set forth in NASD Marketplace Rule 4310(c) (14), which requires that a listed company file with Nasdaq all reports and other documents filed or required to be filed with the SEC Listing Qualification Panel. We received notice in July 2005 that the Nasdaq Market has granted us an extension of time until August 1, 2005 in which to file our Form 10-K for the fiscal year ended December 31, 2004, certain restatements with respect to our historical financial statements, Form 10-Q for the fiscal quarter ended March 31, 2005 and to otherwise meet all necessary listing standards of the Nasdaq Market.

In April 2005, our Board of Directors declared a regular cash dividend of $0.01 per share. The dividend was payable May 9, 2005, to shareholders of record on April 25, 2005 for a total payment of $230,000.

NOTE 1—BASIS OF PRESENTATION

The unaudited consolidated financial statements include the accounts of BIOLASE Technology, Inc. and its consolidated subsidiaries and have been prepared on a basis consistent with the December 31, 2004 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments and the elimination of all material intercompany transactions and balances, necessary to fairly state the information set forth therein. These unaudited, interim, consolidated financial statements do not include all the footnotes, presentations and disclosures normally required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. We previously restated the results of operations for the three and nine months ended September 30, 2004. The restatement is further described in Note 3 of the Consolidated Financial Statements on Form 10-Q/A (Amendment No. 2) for the three and nine months ended September 30, 2004 filed with the Securities and Exchange Commission (“SEC”) on July 19, 2005.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

The results of operations for the three and nine months ended September 30, 2005 are not necessarily indicative of the results to be expected for the full fiscal year or for any other period.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

We sell products domestically to customers through our direct sales force, and internationally through a direct sales force and through distributors. We recognize revenue in accordance with SEC Staff Accounting Bulletin No. 104 which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to our customer or services have been rendered; (3) the price is fixed and determinable; and (4) collectibility is reasonably assured. We record revenue for all sales upon shipment, assuming all other revenue recognition criteria are met.

Although all sales are final, we accept returns of products in certain circumstances and record a provision for sales returns based on historical experience concurrent with the recognition of revenue. The sales returns allowance is recorded as a reduction of accounts receivable, revenue and cost of revenue. As of September 30, 2005 and December 31, 2004, respectively, $358,000 and $420,000 was recorded as a reduction of accounts receivable.

On July 1, 2003, we adopted Emerging Issues Task Force (“EITF”) Issue No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables,” which requires us to evaluate whether the separate deliverables in our arrangements can be unbundled. We determined that the sales of our Waterlase^{^®} system includes separate deliverables consisting of the product, disposables used with the Waterlase, installation and

F-42

training. For these sales, we apply the residual value method, which requires us to allocate the total arrangement consideration less the fair value of the undelivered elements to the delivered element. We determined that the sales of our Diode system include separate deliverables consisting of the product, disposables and training. For these sales, we apply the relative fair value method, which requires us to allocate the total arrangement consideration to the relative fair value of each element. Included in deferred revenue as of September 30, 2005 and December 31, 2004 is $1,368,000 and $1,871,000, respectively, of deferred revenue attributable to the undelivered elements which primarily consist of training and installation.

Extended warranty contracts, which are sold to our non-distributor customers, are recorded as revenue on a straight-line basis over the period of the contracts, which is one year. Included in deferred revenue as of September 30, 2005 and December 31, 2004 is $896,000 and $597,000, respectively, of deferred revenue for our extended warranty contracts.

We recognize revenue for royalties under licensing agreements for our patented technology when the product using our technology is sold. We estimate and recognize the amount sold based on historical performance and current knowledge about the business operations of our licensees. Our estimates have been historically consistent with amounts reported by the licensees. Revenue from royalties was $117,000 and $311,000 for the three and nine months ended September 30, 2005, respectively, and $135,000 and $407,000 for the three months and nine months ended September 30, 2004, respectively.

Provision for Warranty Expense

Products sold directly to end users are under warranty against defects in material and workmanship for a period of one year. Products sold internationally to distributors are covered by a warranty on parts for up to 14 months. We estimate warranty costs at the time of product shipment based on historical experience. Estimated warranty expenses are recorded as an accrued liability, with a corresponding provision to cost of revenue.

Changes in the product warranty accrual, including expenses incurred under our initial and extended warranties, for the nine months ended September 30, 2005 and 2004 were as follows:


	Nine Months Ended September 30,
	2005			2004
Beginning balance	$	911,000		$	727,000
Provision for estimated warranty cost		2,559,000			1,816,000
Warranty expenditures		(2,499,000	)		(1,644,000	)

Ending balance	$	971,000		$	899,000

Stock-based Compensation

We measure compensation expense for stock-based employee compensation plans using the intrinsic value method in accordance with Accounting Principles Board (“APB”) Opinion No. 25. As the exercise price of all options granted under these plans was equal to the fair market price of the underlying common stock on the grant date, no stock-based employee compensation cost is recognized in the consolidated statements of operations. For the three and nine months ended September 30, 2005 we recognized compensation expense in the amount of $0 and $189,000, respectively, related to a cashless option exercise. For the three and nine months ended September 30, 2004, no compensation expense was recognized.

On December 31, 2002, the Financial Accounting Standards Board (the “FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 148, “Accounting for Stock Based Compensation Transition and Disclosure,” which amends SFAS No. 123. SFAS No. 148 requires more prominent and more frequent disclosures about the effects of stock-based compensation by presenting pro forma net (loss) income pro forma net (loss) income per share and other disclosures concerning our stock-based compensation plan.

Net (Loss) Income Per Share—Basic and Diluted

Basic net (loss) income per share is computed by dividing net (loss) income by the weighted average number of common shares outstanding for the period. In computing diluted (loss) income per share, the weighted average number of shares outstanding is adjusted to reflect the effect of potentially dilutive securities.

F-44

Stock options totaling 3,742,000 for both the three and nine months ended September 30, 2005 and stock options totaling 3,396,000 and 514,000 for the three and nine months ended September 30, 2004, respectively, were not included in the diluted (loss) earnings per share amounts as their effect would have been anti-dilutive.

Weighted average shares outstanding—diluted	23,150,000	23,409,000	22,984,000	24,475,000

Inventory

We value inventory at the lower of cost or market (determined by the first-in, first-out method). We periodically evaluate the carrying value of inventory and maintain an allowance for obsolescence to adjust the carrying value to the lower of cost or market, based on physical and technical functionality as well as other factors affecting the recoverability of the asset through future sales. The allowance for obsolescence is adjusted based on such evaluation, with a corresponding provision included in cost of revenue. Components of inventory, net of an allowance for excess and obsolete items of $1,161,000 and $687,000 as of September 30, 2005 and December 31, 2004, respectively, were as follows:


	September 30, 2005		December 31, 2004
Materials	$	3,868,000	$	4,842,000
Work-in-process		2,066,000		887,000
Finished goods		4,593,000		2,451,000

Inventory	$	10,527,000	$	8,180,000

Property, Plant and Equipment

We state property, plant and equipment at acquisition cost less accumulated depreciation and amortization. The cost of property, plant and equipment is depreciated using the straight-line method over the estimated useful lives of the respective assets, except for leasehold improvements, which are amortized over the lesser of the estimated useful lives of the respective assets or the related lease terms. Maintenance and repairs are expensed as incurred. Upon sale or disposition of assets, any gain or loss is included in the consolidated statements of operations.

We continually monitor events and changes in circumstances, which could indicate that the carrying balances of property, plant and equipment may exceed the undiscounted expected future cash flows from those assets. If such a condition were to exist, we would recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.

F-45

Property, plant and equipment consisted of the following:


	September 30, 2005			December 31, 2004
Land	$	288,000		$	321,000
Building		791,000			883,000
Leasehold improvements		279,000			209,000
Equipment and computers		2,583,000			1,897,000
Furniture and fixtures		996,000			761,000

Property, plant and equipment, net	$	3,370,000		$	3,025,000

Intangible Assets and Goodwill

In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets,” goodwill and other intangible assets with indefinite lives are no longer subject to amortization but are tested for impairment annually or whenever events or changes in circumstances indicate that the asset might be impaired. We conducted our annual impairment analysis of our goodwill and trade names as of June 30, 2004 and 2005 and concluded there had not been an impairment. During the fourth quarter of 2004, we changed our strategy to focus our sales efforts on high-end laser products such as the new Waterlase MD^™ product, which was first sold during the fourth quarter of 2004. This conclusion was due to the increased competition for relatively low-priced laser devices. As a result, the actual sales of Diolase Plus^™ were below our original expectations and we expect this trend to continue. We estimated the fair value of the Diolase Plus trade name using our revised strategy and based on a relief from royalty approach using discounted cash flows from revised projected Diolase Plus revenue. The $747,000 excess of the carrying value over the asset’s estimated fair value has been recorded as a charge to operations during the year ended December 31, 2004. We performed our analysis at December 31, 2004 as a result of the change in our business strategy in December 2004, which we believed warranted an updated assessment. We will continue to monitor circumstances and events for possible impairment, and in any event we will perform our next annual impairment test in June 2006 in accordance with our historical practice.

Intangible assets with finite lives continue to be subject to amortization, and any impairment is determined in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” We believe no event has occurred that would trigger an impairment of these intangible assets. We recorded amortization expense for the three and nine months ended September 30, 2005, of $93,000 and $268,000, respectively, and $62,000 and $187,000, respectively, for the same periods of 2004. Other intangible assets consist of an acquired customer list and a non-compete agreement.

Non-operating (Loss) Income, Net

Non-operating (loss) income, net consists of interest income and expense, marketable securities gains and losses and foreign currency gains and losses. The operations and cash flows of our German subsidiary, for which the Euro is the functional currency, are translated to U.S. dollars at average exchange rates during the period and its assets and liabilities are translated at the end-of-period exchange rates. Translation gains or losses related to the net assets located in Germany are shown as a component of accumulated other comprehensive loss in stockholders’ equity. Foreign currency gains or losses relating to sales and purchase transactions which are denominated in other than U.S. dollars are shown as a net gain or loss in the consolidated statements of income.

The following table presents details of non-operating (loss) income, net:

New Accounting Pronouncements

In June 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections—a replacement of APB No. 20 and FAS No. 3.” SFAS No. 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to the newly adopted accounting principle. SFAS No. 154 also provides guidance for determining whether retrospective application of a change in accounting principle is impracticable and for reporting a change when retrospective application is impracticable. The correction of an error in previously issued financial statements is not an accounting change. However, the reporting of an error correction involves adjustments to previously issued financial statements similar to those generally applicable to reporting an accounting change retrospectively. Therefore, the reporting of a correction of an error by restating previously issued financial statements is also addressed by SFAS No. 154. SFAS No. 154 is required to be adopted in fiscal years beginning after December 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

F-47

the American Jobs Creation Act of 2004” (“AJCA”). The AJCA introduces a special 9% tax deduction on qualified production activities. FAS No. 109-1 clarifies that this tax deduction should be accounted for as a special tax deduction in accordance with Statement No. 109. Pursuant to the AJCA, we will not be entitled to this special deduction in 2005, as the deduction is applied to taxable income after taking into account net operating loss carryforwards, and we have significant net operating loss carryforwards that will fully offset taxable income. We do not expect the adoption of this new tax provision to have a material impact on our consolidated financial position, results of operations or cash flows.

In December 2004, the FASB revised and reissued SFAS No. 123-R, “Share-Based Payment,” which supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.” The revised statement addresses the accounting for share-based payment transactions with employees and other third parties, eliminates the ability to account for share-based payment transactions using APB No. 25 and requires that the compensation costs relating to such transactions be recognized in the consolidated statement of operations. The standard was to become effective July 1, 2005. In March 2005, the SEC released Staff Accounting Bulletin (“SAB”) No. 107, “Share-Based Payment,” to provide public companies additional guidance in applying the provisions of SFAS No. 123-R. Among other things, the SAB describes the staff’s expectations in determining the assumptions that underlie the fair value estimates and discusses the interaction of SFAS No. 123-R with certain existing staff guidance. SAB No. 107 should be applied upon the adoption of SFAS No. 123-R. In April 2005, the SEC amended Regulation S-X to provide a six-month adoption deferral period for public companies. Therefore, SFAS No. 123-R will not become effective for us until January 1, 2006. The new rules provide for one of two transition elections, either prospective application or restatement (back to January 1, 1995). We plan to adopt SFAS No. 123-R on January 1, 2006. We currently are evaluating the impact of this pronouncement on our consolidated financial position, results of operations and cash flows.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs,” which amends part of Accounting Research Bulletin (“ARB”) No. 43, “Inventory Pricing,” concerning the treatment of certain types of inventory costs. The provisions of ARB No. 43 provided that certain inventory-related costs, such as double freight and re-handling might be “so abnormal” that they should be charged against current earnings rather than be included in the cost of inventory. As amended by SFAS No. 151, the “so-abnormal” criterion has been eliminated. Thus, all such (abnormal) costs are required to be treated as current-period charges under all circumstances. In addition, fixed production overhead should be allocated based on the normal capacity of the production facilities, with unallocated overhead charged to expense when incurred. SFAS No. 151 is required to be adopted for fiscal years beginning after June 15, 2005. We do not believe its adoption will have a material impact on our financial position, results of operations or cash flows.

NOTE 3—INVESTMENTS IN MARKETABLE SECURITIES

Our investments are comprised of U.S. government notes and bonds and have been categorized as available-for-sale. We account for our marketable securities in accordance with SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” Investments classified as “available-for-sale” are reported at fair value with unrealized gains (losses) recorded as a component of comprehensive loss until realized. In the event the fair value of an investment declines and is deemed to be other than temporary, we write down the

F-48

carrying value of the investment to its fair value. As of September 30, 2005, no securities were impaired. The following summarizes our investments as of September 30, 2005:


	Amortized Cost		Unrealized Loss			Fair Value
Short-term:
U.S. Treasury debt securities	$	10,039,000	$	(105,000	)	$	9,934,000

NOTE 4—ACCOUNTS PAYABLE AND ACCRUED LIABILITIES

Accounts payable includes $115,000 and $126,000 of customer deposits at September 30, 2005 and December 31, 2004, respectively.

Components of accrued liabilities were as follows:


	September 30, 2005		December 31, 2004
Payroll and benefits	$	2,687,000	$	2,733,000

Total accrued liabilities	$	7,064,000	$	8,467,000

We reimburse our customers for their costs related to certain marketing programs. On our purchase orders we state the amount that we will reimburse the customers, which is recorded as a reduction of revenue when revenue of the purchase order is recognized. Amounts due to customers represent our obligation to reimburse our customers for these programs.

NOTE 5—STOCKHOLDERS’ EQUITY

Net shares issued as a result of stock option exercises for the three and nine months ended September 30, 2005 totaled 217,000 and 324,000 shares, respectively, which resulted in net proceeds of approximately $731,000 and $1,226,000, respectively. Shares issued as a result of stock option exercises for the three and nine months ended September 30, 2004 totaled 90,000 and 335,000 shares, respectively, which resulted in proceeds of approximately $284,000 and $977,000, respectively.

In August 2005, our Board of Directors voted to discontinue our dividend policy of paying a cash dividend of $0.01 per share every other month which the Board had adopted in July 2004. Dividends totaling $235,000 were declared and paid for both the three and nine months ended September 30, 2004 to stockholders of record under this program. For the three and nine months ended September 30, 2005, dividends totaling $230,000 and $689,000, respectively, were declared and paid to stockholders of record under this program.

In January 2005, we issued 361,664 shares of common stock and a five-year warrant exercisable into 81,037 shares of common stock and an additional 45,208 shares of common stock placed into escrow related to the legal settlement with Diodem. See Note 8—COMMITMENTS AND CONTINGENCIES.

In July 2004, our Board of Directors authorized a 1.25 million share repurchase program. In August 2004, our Board of Directors authorized the repurchase of an additional 750,000 shares of our common stock, increasing the total shares repurchase program to 2.0 million shares of our common stock. During the year ended December 31, 2004, we repurchased approximately 1,963,500 shares at an average price of $8.35 per share, of

F-49

which approximately 1.5 million shares at an average price of $8.81 per share were repurchased as of September 30, 2004. No repurchase was made during the three and nine months ended September 30, 2005.

In March 2004, as a result of the completion of a public underwritten offering, we issued 2,500,000 shares of common stock at an offering price of $18.50 per share. Gross proceeds from the offering were $46,250,000, before underwriting discounts and commissions of $2,875,000. In connection with the offering, we incurred direct expenses of approximately $1,507,000, which had been included in other assets and were reclassified as a reduction of additional paid-in capital when the common stock was issued.

NOTE 6—COMPREHENSIVE (LOSS) INCOME

Components of comprehensive (loss) income were as follows:

NOTE 7—INCOME TAXES

Based upon our operating losses during 2004 and the available evidence, management determined that it is more likely than not that the deferred tax assets as of December 31, 2004 would not be realized. Consequently, we recorded a valuation allowance for our net deferred tax asset in the amount of $21,100,000 as of December 31, 2004. In this determination, we considered factors such as our earnings history, future projected earnings and tax planning strategies. If sufficient evidence of our ability to generate sufficient future taxable income becomes apparent, we may reduce our valuation allowance, resulting in income tax benefits in our statement of operations and in additional paid-in-capital. Management continues to evaluate the potential realization of our deferred tax assets and assesses the need for reducing the valuation allowance periodically. As of September 30, 2005 we determined that a valuation allowance is still required. As a result of the valuation allowance, we recognized a modest tax provision that primarily related to our foreign operations and certain U.S. deferred tax liabilities that could not be offset against our deferred tax assets. We will continue to evaluate the potential realization of our deferred tax assets during the remainder of 2005 to determine whether the valuation allowance should be reduced.

NOTE 8—COMMITMENTS AND CONTINGENCIES

Leases and Commitments

We lease our manufacturing facilities in San Clemente, California, certain equipment and automobiles under operating lease arrangements. Future minimum rental commitments under operating leases and under other contractual obligations as of September 30, 2005 for each of the years ending December 31 are as follows:


Remainder of 2005	$	180,000
2006		334,000
2007		66,000
2008		31,000
2009		25,000
2010		25,000

Total	$	661,000

Licensed Patent Rights

In February 2005, we purchased a license to use certain patent rights for technology in the field of presbyopia totaling $2,000,000 including related transaction costs, from Surgilight, Inc. (“Surgilight”). Additional consideration totaling $200,000 will be expensed as incurred in 2006 through 2010, in accordance with FAS No. 2, “Accounting for Research and Development Costs.”

Employee Arrangements and Other Compensation

Certain executive officers and managers have employment agreements that provide us with the ability to terminate their employment at will. However, under the terms of the agreements we are obligated to pay them severance compensation in the event we terminate their employment. Additionally, we have agreements with certain employees to pay bonuses based on targeted performance criteria and specified service retention periods.

In June 2005, our Board of Directors resolved to make a one-time payment of $90,000 to Mr. George d’Arbeloff in connection with his service as audit committee chair and the extraordinary efforts he contributed in connection with the 2004 audit (and contemporaneous restatement of 2002 and 2003 financial statements). This amount was recorded as an expense in the third quarter of 2005.

Litigation

In August 2004, we and certain of our officers were named as defendants in several putative shareholder class action lawsuits filed in the United States District Court for the Central District of California. The complaints purport to seek unspecified damages on behalf of an alleged class of persons who purchased our common stock between October 29, 2003 and July 16, 2004. The complaints allege that we and our officers violated federal securities laws by failing to disclose material information about the demand for our products and the fact that we would not achieve the alleged forecasted growth. The claimed misrepresentations include certain statements in our press releases and the registration statement we filed in connection with our public offering of stock in March 2004. In addition, three stockholders have filed derivative actions in the state court in California seeking recovery on behalf of BIOLASE, alleging, among other things, breach of fiduciary duties by those individual defendants and by the members of our Board of Directors. The cases are still in the pretrial stage and no discovery has been conducted by any of the parties. However, based on the facts presently known, our management believes we have meritorious defenses to these actions and intends to vigorously defend them. As of September 30, 2005, no amounts have been recorded in the consolidated financial statements for these matters since management believes that it is not probable we have incurred a loss contingency.

F-51

In January 2005, we acquired the intellectual property portfolio of Diodem consisting of certain U.S. and international patents of which four were asserted against us, and settled the existing litigation between us and Diodem, for consideration of $3,000,000 in cash, 361,664 shares of common stock (valued at the common stock fair market value on the closing date of the transaction for a total of approximately $3,500,000), and a five-year warrant exercisable into 81,037 shares of common stock at an exercise price of $11.06 per share. In addition, if certain criteria specified in the purchase agreement are satisfied on or before July 2006, 45,208 additional shares we have placed in escrow may be released to Diodem and we will incur an expense equal to the fair market value of those shares at the time of their release. The common stock issued, the escrow shares and the warrant shares have certain registration rights. The total consideration was estimated to have a value of approximately $7,000,000 excluding the value of the shares held in escrow, which are contingent in nature, but including the value of the patents acquired in January 2005. As of December 31, 2004, we accrued approximately $6,400,000 for the settlement of the existing litigation with $3,000,000 included in current liabilities and $3,400,000 recorded as a long-term liability. In January 2005, upon issuance of the consideration, we also recorded an intangible asset of $530,000 representing the estimated fair value of the intellectual property acquired. The estimated fair value of the patents was determined using a relief from royalty and a discounted cash flow methodology. As a result of the acquisition, Diodem immediately withdrew its patent infringement claims against us and the case was formally dismissed on May 31, 2005. We did not pay and have no obligation to pay any royalties to Diodem on past or future sales of our products, but we agreed to pay additional consideration if any of the acquired patents held by us are licensed to a third party. In order to secure performance by us of these financial obligations, the parties entered into an intellectual property security agreement, pursuant to which, subject to the rights of existing creditors and the rights of any future creditors to the extent provided in the agreement, we granted Diodem a security interest in all of their right, title and interest in the royalty patents. In addition, we will be required, by January, 2006, to provide Diodem a ten-year letter of credit from a bank in the amount of $500,000 as additional security.

We determined the fair value of the warrants, which totaled $443,000 using the Black-Scholes model with the following assumptions:


Term		5 years
Volatility		67	%
Annual dividend per share	$	0.00
Risk-free interest rate		3.73	%

The warrants and common stock were issued in January 2005.

From time to time, we are involved in other legal proceedings incidental to our business, but at this time we are not party to any other litigation that is material to our business.

Securities and Exchange Commission Inquiry

We restated our previously issued financial statements in September of 2003 to reflect a change in the timing of revenue recognition. We received informal requests from the SEC to voluntarily provide information

F-52

relating to the September 2003 restatement of our consolidated financial statements. We provided information to the SEC and if we receive any additional requests for information, we intend to continue to do so. In accordance with its normal practice, the SEC has not advised us when its inquiry might be concluded.

NOTE 9—SEGMENT INFORMATION

We currently operate in a single business segment. Revenue of our Waterlase system, our principal product, represented 78% and 83% of net revenue for the three and nine months ended September 30, 2005, respectively, and 80% and 81%, respectively, for the same periods of 2004. For the three and nine months ended September 30, 2005, sales in Europe, Middle East and Africa (“EMEA”) accounted for approximately 11% and 10%, respectively, of our net revenue, and sales in Canada, Asia, Latin America and Pacific Rim countries accounted for approximately 17% and 18%, respectively, of the net revenue. For the three and nine months ended September 30, 2004, sales in EMEA accounted for approximately 14% and 12%, respectively, of our net revenue, and sales in Canada, Asia, Latin America and Pacific Rim countries accounted for approximately 12% and 15%, respectively, of our net revenue. Net revenue by geographic location based on the location of customers was as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2005		2004		2005		2004
United States	$	8,447,000	$	9,162,000	$	31,043,000	$	30,325,000
Europe, Middle East and Africa		1,291,000		1,711,000		4,347,000		5,207,000
Canada, Asia, Latin America and Pacific Rim		1,917,000		1,437,000		7,632,000		6,046,000

	$	11,655,000	$	12,310,000	$	43,022,000	$	41,578,000

NOTE 10—CONCENTRATIONS

Many of our customers finance their purchases through third-party leasing companies. In these transactions, the leasing company is considered the purchaser, although it is the dentist who is our customer and to whom we market and sell and from whom we receive the initial binding purchase commitment. Net revenue generated from dentists who financed their purchase through one leasing company was approximately 33% and 32%, respectively, for the three and nine months ended September 30, 2005, and 33% and 32%, respectively, for the same periods of 2004. Other than these transactions, no distributor or customer accounted for more than 10% of net revenue for the three months and nine months ended September 30, 2005 and September 30, 2004.

Financial instruments that subject us to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. We maintain our cash accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit of $100,000 for each account.

Accounts receivable concentrations have resulted from sales activity to the one leasing company mentioned above. Accounts receivable for the one leasing company totaled $1,560,000 and $608,000, respectively, at September 30, 2005 and September 30, 2004. We had accounts receivable from one distributor that totaled $716,000 as of September 30, 2005. No other single customer accounted for more than 10% of our accounts receivable at September 30, 2005 or September 30, 2004.

Certain components of our products, particularly specialized components used in our lasers, are currently available only from a single source or limited sources. We have no written supply contracts with our key suppliers; instead, we purchase certain materials and components using purchase orders that are subject to change, deferral or cancellation with only limited notice to the suppliers.

F-53

NOTE 11—BANK LINE OF CREDIT

At September 30, 2005, we had a $10.0 million credit facility with a bank. On September 19, 2005, the Company entered into a third amendment to our credit facility with the bank which extended the term from September 30, 2005 to September 30, 2006. In addition, certain material covenants of the credit facility were modified to decrease the required minimum tangible net worth from $30.0 million to $24.0 million, decrease the required minimum balance of cash (including investments in U.S. Treasuries) from $20.0 million to $12.0 million, and amend the quarterly profitability condition commencing with the fiscal quarter ended March 31, 2006. At September 30, 2005, $5.0 million was outstanding on the credit facility. Borrowings under the facility bear interest at LIBOR plus 2.25% for minimum borrowing amounts of $500,000 and with two business days notice or at a variable rate equivalent to prime rate for amounts below $500,000 or with less than two business days notice and are payable on demand upon expiration of the facility. All borrowings during the first nine months of 2005 were at prime rate. We granted the bank a security interest in and to all equipment, inventory, accounts receivable and other assets of the Company. As of September 30, 2005, we were non-compliant with our covenants relating to minimum tangible net worth and debt to tangible net worth for which we received a waiver in November 2005.

In November 2005, we also entered into a fourth amendment to our credit facility with the bank which eliminates all of our financial covenants, including the minimum cash balance of $12.0 million. Under the new amendment, we agreed to collaterize the facility with our short-term investment in U.S. Treasury debt securities which had a fair market value of $9.9 million as of September 30, 2005. Although the new amendment was entered into in November 2005, our short-term investment is shown as restricted on our consolidated balance sheets as of September 30, 2005 based on management’s intent.

NOTE 12—SUBSEQUENT EVENTS

In April 2005, we received a notification from The NASDAQ Stock Market, Inc. concerning our failure to comply with the requirement for continued listing set forth in NASD Marketplace Rule 4310(c) (14), which requires that a listed company file with NASDAQ all reports and other documents filed or required to be filed with the SEC. In July 2005, NASDAQ granted us an extension of time until August 1, 2005 in which to file our Form 10-K for the fiscal year ended December 31, 2004, certain restatements with respect to our historical financial statements, and our Form 10-Q for the fiscal quarter ended March 31, 2005 and to otherwise meet all necessary listing standards of the NASDAQ National Market. On July 19, 2005, we filed (i) our Form 10-K for the fiscal year ended December 31, 2004 which included consolidated financial statements for the year ended December 31, 2004 and restated consolidated financial statements as of December 31, 2003 and the two years then ended and (ii) amended Form 10-Qs for the fiscal quarters ended March 31, 2004, June 30, 2004 and September 30, 2004, which included restated financial statements for the prior comparative periods as well. In July 2005, we requested an additional extension of time from NASDAQ in which to file our Forms 10-Q for the fiscal quarters ended March 31, 2005 and June 30, 2005. In August 2005, we received additional notices from NASDAQ regarding the late filing of the second quarter Form 10-Q and granting us the requested extension of time until September 30, 2005 in which to file our first and second quarter Forms 10-Q, and to otherwise meet all necessary listing standards. We filed our first and second quarter Forms 10-Q on September 30, 2005. On October 6, 2005, we announced that we had received notice from NASDAQ that we had evidenced compliance with all requirements for continued listing and that our trading symbol had been restored to “BLTI.”

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors American Medical Technologies, Inc.

We have audited the accompanying statements of selected assets and liabilities of the American Dental Laser division (“Division”) of American Medical Technologies, Inc. (“Company”) as of December 31, 2002 and 2001 and the related statements of revenues and expenses for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the statements of selected assets and liabilities of the American Dental Laser division of American Medical Technologies, Inc. as of December 31, 2002 and 2001 and the statements of revenues and expenses for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Division will continue as a going concern. As discussed in Note 1 to the financial statements, the Division has incurred a net loss of $3,750,635 for the year ended December 31, 2002. This matter raises substantial doubt about the Division’s ability to continue as a going concern. Management’s plans in regard to these matters are described in Note 1 to the financial statements. The financial statements do not include any adjustments to reflect the possible future effect on the recoverability and classification of assets that may result from the outcome of this uncertainty.

AMERICAN DENTAL LASERS

(FORMERLY A DIVISION OF AMERICAN MEDICAL TECHNOLOGIES, INC.)

NOTES TO FINANCIAL STATEMENTS

NOTE 1—DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

American Dental Lasers (the “Division” or “ADL”) was a division of American Medical Technologies, Inc. (“AMT”), which develops, manufactures and markets high technology products designed primarily for general dentistry. The accompanying financial statements are derived from the historical books and records of AMT and present the statement of selected assets and liabilities and revenues and expenses applicable to the U.S. laser operations of AMT. On May 21, 2003, AMT entered into an Asset Purchase Agreement with BioLase Technology, Inc. (“BioLase”) for the sale of AMT’s laser assets for cash and stock with an aggregate value of approximately $5.6 million. The purchase price consists of $1,825,000, to be paid to Bank One to retire AMT’s debt to Bank One, and 307,500 shares of BioLase common stock.

Going Concern—The Division’s financial statements are prepared using accounting principles generally accepted in the United States of America applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Division incurred a net loss of $3,750,635 for the year ended December 31, 2002, which raises substantial doubt about the Division’s ability to continue as a going concern.

Basic of Presentation—The accompanying unaudited financial statements of ADL for the three-month periods ended March 31, 2002 and 2003 have been prepared by management in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments and allocations, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included.

The statements of selected assets and liabilities have been prepared using the historical basis of accounting and include all of the assets and liabilities specifically identifiable with the U.S. operations of the Division. The statements of selected assets and liabilities do not include assets and liabilities of AMT which are not specifically identifiable with the Division. These assets and liabilities are as follows:

•

Trade accounts receivable arising from the sale of laser parts;

•

Prepaid insurance and similar prepaid expenses;

•

Property and equipment of AMT other than equipment acquired by BioLase;

•

Accounts payable for amounts due to vendors supplying solely non-laser inventory, a combination of laser and non-laser inventory, or selling, general and administrative goods and services; and

•

Accrued liabilities such as accrued warranty, restructuring and compensation costs.

Allocation of these assets and liabilities using methods based upon revenues, net loss, assets and equity would not necessarily be reflective of the nature of the costs incurred. Depreciation, warranty, restructuring, compensation and interest expenses have been allocated to the Division and are considered intercompany charges for use of assets and resources that are not specifically identifiable with the Division.

The statement of revenues and expenses includes all revenue and expenses attributable to the U.S. operations of the Division, including a corporate allocation of costs of shared services (including legal, finance, sales, and marketing and corporate office expenses). These costs are allocated to the Division on a basis that is considered by management to reflect most fairly or reasonably the utilization of services provided to or the benefit obtained by the Division, such as the percentage of revenues or actual utilization. Therefore, AMT used a percentage of revenue approach in allocating these charges such that approximately 34.08%, 53.46%, 52.06%

F-59

AMERICAN DENTAL LASERS

(FORMERLY A DIVISION OF AMERICAN MEDICAL TECHNOLOGIES, INC.)

NOTES TO FINANCIAL STATEMENTS—(Continued)

and 54.42% of these costs and expenses are allocated to ADL for the three months ended March 31, 2003 and 2002 and the years ended December 31, 2002 and 2001, respectively. Interest expense, which represents interest on bank debt incurred by AMT, was allocated to ADL, based on the percentage of revenue approach using these same percentages. Management believes the methods used to allocated these amounts are reasonable. However, the financial information included herein does not necessarily reflect what the financial position or results of operation would have been had the Division operated as a stand-alone public entity during the periods covered, and may not be indicative of future results of operations or financial position. For the years ended December 31, 2002, and 2001 and the three months ended March 31, 2002 and 2003, such allocated costs amounted to $3,381,838, $4,561,261, $933,639 and $244,787, respectively, and are included in operating expenses.

The details of the allocation were as follows:

Accounting Estimate—The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. The determination of the Division’s valuation allowance for inventory is a significant estimate that could change materially over the next year should circumstances affecting the Division’s current sales volumes change.

Inventories—Inventories consist of the following:


	December 31, 2001		December 31, 2002		March 31, 2003
					(unaudited)
Finished goods	$	1,013,825	$	705,722	$	597,939
Raw materials, parts and supplies, net of reserve for slow moving inventory of $297,700, $1,449,214 and $1,594,870, respectively		1,224,029		471,642		395,685

	$	2,237,854	$	1,177,364	$	993,624

The Division’s reserve for slow moving inventory is evaluated periodically based on its current and projected sales and usage. Prior to the fourth quarter 2002, the Division’s inventory reserve was calculated by comparing on hand quantities as of the measurement date to the prior twelve months’ sales. The reserve calculation assumed that sales for each unit or part will not be less than sales for the prior twelve months. Changes to the reserves were included in costs of goods sold and had a direct impact on the Division’s financial position and result of operations. The reserve was calculated differently for finished units than it was for parts. For parts, when the on hand quantity exceeded the prior twelve months’ sales and usage, the excess inventory

NOTES TO FINANCIAL STATEMENTS—(Continued)

was calculated by subtracting the greater of the prior twelve months’ sales and usage or a base quantity of 50 from the quantity on hand. This excess was then 100% reserved. The base quantity of 50 represented management’s determination of the minimum quantity of parts needed to fulfill its service, repair, and warranty obligations for five years. All parts or units with less than twelve months of sales or usage history were excluded from the calculation.

In the fourth quarter of 2002, the Division changed certain assumptions it uses in computing the inventory valuation allowance. The inventory reserve calculation remained the same for finished units, but was changed for parts. For parts, the new policy assumes that three years of projected parts usage of any given part will not be subject to a valuation allowance. Any parts on hand exceeding three years of projected usage are subject to a 100% valuation allowance. For purposes of computing the valuation allowance at December 31, 2002 and March 31, 2003, parts usage was projected at 50% of the prior 12 months part usage. This change in methodology resulted in an increase in the reserve for slow moving inventory of $854,996 versus what it would have been under the prior methodology for the year ended December 31, 2002.

Restructuring Costs—In the second quarter of 2002 AMT adopted a restructuring plan that called for the closure of its remaining sales and service branches and significant reductions in the number of employees in mid-June. As part of the restructuring, a total of 49 employees were terminated, comprised of field sales and service personnel, manufacturing employees and administrative personnel. As of September 30, 2002 AMT had vacated all of its former sales and service centers. Costs such as employee severance, lease termination costs and other exit costs have been recorded as of the date the restructuring plan was finalized. None of the expenses accrued as part of the restructuring have any benefit for future operations. Certain costs were estimated based on the latest available information. Restructuring costs were allocated to the Division based on the Division’s revenues versus total AMT revenues.

Equipment—Equipment is stated at cost less accumulated depreciation and includes only the equipment purchased by Biolase. Depreciation is computed by the straight-line method over the estimated useful lives of the related assets, which range from five to seven years. Accumulated depreciation aggregated $11,703, $7,236 and $12,270 at December 31, 2002 and 2001 and March 31, 2003, respectively.

Intangible assets—During 2001, the Company’s distributorship agreement with its Japanese supplier expired. The Company has been unable to secure a distributor for its products in Japan. As a result, sales in Japan were nominal in 2002. The Company had intangible assets with a carrying value of $615,924 relating to various rights to distribute products to Japan. These circumstances are indicative of an impairment of these intangible assets. These intangible assets were charged off December 2002 in accordance with FASB Statement No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which was adopted on January 1, 2002. This impairment expense is included in Selling, General and Administrative Expenses in the statement of revenues and expenses.

Revenue Recognition—The Division recognizes revenue from product sales when all of the following criteria are met: 1) a contract or sales arrangement exists; 2) products have been shipped and title has been transferred or services have been rendered; 3) the price of the products or services is fixed or determinable; 4) no further obligation exists on the part of the Division (other than warranty obligations); and 5) collectibility is reasonably assured. The Division recognizes the related estimated warranty expense when title is transferred to the customer, generally upon shipment. The Division has licensed technology to various companies for use in certain of their products. The royalties from these licenses are based on actual product sold by these companies. Accordingly, the Division recognizes royalty revenues as product is sold. The Division recognizes revenue on certain sales to two of its international distributors under terms that require shipment to a local independent

NOTES TO FINANCIAL STATEMENTS—(Continued)

warehouse. The Division’s policy is to include shipping and handling costs, net of the related revenues, which are not material in costs of goods sold. There are no significant estimates or assumptions involved in determining the appropriate recognition of revenues.

Stock Based Compensation—AMT grants stock options for a fixed number of shares to employees with an exercise price no less than the fair value of the shares at the date of grant. AMT accounts for stock option grants in accordance with APB Opinion No. 25, Accounting for Stock Issued to Employees, and, accordingly, recognizes no compensation expense for the stock option grants. Had the Company accounted for the stock under the fair value method, the Division’s net loss would not have been significantly impacted.

Income Taxes—The Division’s operations are included in the consolidated tax returns of AMT. Income tax expense (benefit) was allocated to the Division based on the pro rata revenues of the Division versus AMT as a whole for each of the respective periods included in the accompanying financial statements.

Advertising—The Division expenses advertising costs as incurred. Advertising expense approximated $131,000 and $73,000 in 2002 and 2001, respectively and $55,000 and $1,000 for the three months ended March 31, 2002 and 2003, respectively.

New Accounting Standards and Disclosures—In July 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.” SFAS 146 requires that a liability for a cost that is associated with an exit or disposal activity be recognized when the liability is incurred. It supersedes the guidance in EITF Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring).” Under EITF 94-3, an entity recognized a liability for an exit cost on the date that the entity committed itself to an exit plan. Under SFAS 146, an entity’s commitment to a plan does not, by itself, create a present obligation that meets the definition of a liability. SFAS 146 also establishes that fair value is the objective for the initial measurement of the liability. SFAS 146 will be effective for exit or disposal activities that are initiated after December 31, 2002, with early application encouraged. The adoption of SFAS 146 did not have a material impact on the Company.

NOTE 3—LITIGATION AND CONTINGENCIES

As part of the consideration in the execution of the Asset Purchase Agreement with BioLase, AMT and BioLase agreed to enter into a Stipulation for Dismissal with Prejudice in the patent infringement lawsuit filed by BioLase against AMT in the U.S. District Court for the Central District of California, Southern District. The stipulation settles all matters between the parties arising from that lawsuit, dismisses the complaint and prohibits BioLase from bringing any further action based on the alleged patent infringement.

Also in connection with the Asset Purchase Agreement with BioLase, AMT agreed to cooperate with BioLase in the defense of the patent infringement lawsuit filed in the Federal District Court for the Central District of California by Diodem. That suit, in which AMT has not been served, alleges patent infringement on four patents and seeks injunctive relief and an unspecified amount of actual and trebled damages. Because the assets which were alleged to infringe on Diodem patents were sold to BioLase in the Asset Purchase Agreement, AMT assigned to BioLase its rights to recovery under that lawsuit, and BioLase agreed to indemnify AMT against any loss it may incur as a result of its cooperation with BioLase to take action it would not otherwise have taken in the defense of the suit.

Item 14. Indemnification of Directors and Officers

The Registrant’s Certificate of Incorporation, as amended, provides that the Registrant’s directors will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for (i) any breach of their duty of loyalty to the Registrant or its stockholders, (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the General Corporation Law of the State of Delaware (the “Delaware Law”), or (iv) any transaction from which the director derives an improper personal benefit.

Article X of the Registrant’s Amended and Restated Bylaws provides that the Registrant will indemnify any director or officer, or former director or officer, who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, to the fullest extent authorized by the Delaware Law, against all costs, charges, expenses, liabilities and losses (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered in connection with such action, suit or proceeding. The Registrant also will indemnify any such director or officer, or any such former director or officer, against expenses incurred in defending any such action, suit or proceeding in advance of its final disposition, provided that, if required by the Delaware Law, the payment of such expenses will be made only upon delivery to the Registrant of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified.

Article X of the Registrant’s Amended and Restated Bylaws further provides that in the event a director or officer has to bring suit against the Registrant for indemnification and is successful, the Registrant will pay such director’s or officer’s expenses of prosecuting such claim; that indemnification provided for by the Amended and Restated Bylaws shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; that the Registrant may purchase and maintain insurance on behalf of a director or officer against any expense, liability or loss, whether or not the Registrant would have the power to indemnify such director or officer against such expense, liability or loss under the Delaware Law; and that to the extent any director or officer is by reason of such position a witness in any action, suit or proceeding, the Registrant shall indemnify him or her against all costs and expenses actually and reasonably incurred by him or her in connection therewith.

II-1

The Registrant’s employment agreement with its President and Chief Executive Officer, Robert E. Grant, provides that the Registrant will, to the maximum extent permitted under Delaware law, indemnify Mr. Grant against any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, threatened or initiated against Mr. Grant by reason of the fact that he was serving as an officer, director, employee or agent of the Registrant or was serving at the request of the Registrant as an officer, director, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

The Registrant’s employment agreement with its Chief Technology Officer and Vice Chairman of the Board, Jeffrey W. Jones, provides that the Registrant will, to the maximum extent permitted under the Delaware Law, indemnify Mr. Jones against any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, threatened or initiated against Mr. Jones by reason of the fact that he was serving as a director or officer.

In July 2005 the Registrant entered into separate but similar indemnification agreements (the “Indemnification Agreements”) with the following directors and officers: Federico Pignatelli, Jeffrey W. Jones, George V. d’Arbeloff, Dr. Robert Anderton, Robert E. Grant, Keith G. Bateman and James M. Haefner. In December 2005, we entered into an Indemnification Agreement with Richard L. Harrison, our newly appointed Executive Vice President and Chief Financial Officer. The form of the Indemnification Agreement was approved by our stockholders at our annual meeting of stockholders held on November 15, 2005. Pursuant to the terms of the Indemnification Agreements the Registrant will indemnify such directors and officers to the fullest extent permitted under Delaware law and the Certificate of Incorporation of the Registrant. The Indemnification Agreements provide that, among other things, (i) the Registrant will indemnify such directors and officers if and wherever they are made party to a proceeding or are threatened to be made a party to a proceeding, (ii) the Registrant will advance all reasonable expenses incurred, whether prior to or after a final determination of a proceeding and (iii) the Registrant will use all reasonable efforts to provide and maintain directors’ and officers’ liability insurance policies.

of the case, such director or officer is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

The Registrant maintains directors’ and officers’ liability insurance covering its directors and officers.

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) If the Registrant is relying on Rule 430B:

(A) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

II-7

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(ii) If the Registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is

II-8

asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-9
