PROXY STATEMENT

This proxy statement is furnished in connection with the solicitation of proxies by the Board of Directors of Mercury Computer Systems, Inc. (the “Corporation”) for use at the Special Meeting in Lieu of the 2004 Annual Meeting of Shareholders to be held on Monday, November 15, 2004, at the time and place set forth in the accompanying notice of the meeting, and at any adjournments or postponements thereof. The approximate date on which this proxy statement and form of proxy are first being sent to shareholders is on or about October , 2004.

The Corporation’s principal executive offices are located at 199 Riverneck Road, Chelmsford, Massachusetts 01824, telephone number (978) 256-1300.

VOTING AND REVOCABILITY OF PROXIES

If the enclosed proxy is properly executed and is received prior to the meeting, it will be voted in the manner directed by the shareholder. If no instructions are specified with respect to any particular matter to be acted upon, proxies will be voted:

•

FOR the election of the nominees for Class I director as set forth in this proxy statement;

•

FOR the amendment to the Corporation’s 1997 Stock Option Plan, as amended and restated (the “1997 Plan”), to increase the number of shares authorized for issuance thereunder; and

•

FOR the amendment to the Corporation’s Articles of Organization, as amended (the “Articles of Organization”), to increase the number of shares of common stock, par value $.01 per share (“Common Stock”), authorized for issuance thereunder.

It is not anticipated that any matters other than those set forth in this proxy statement will be presented at the meeting. If other matters are presented, proxies will be voted in accordance with the discretion of the proxy holders.

Any person giving the enclosed form of proxy has the power to revoke it by voting in person at the meeting, by giving a duly executed proxy bearing a later date or by giving written notice of revocation to the Secretary of the Corporation any time before the proxy is exercised. A shareholder of record attending the meeting may vote in person whether or not a proxy has been previously given, but the presence, without further action, of a shareholder at the meeting will not constitute revocation of a previously given proxy.

QUORUM AND REQUIRED VOTE

The holders of a majority in interest of all shares of Common Stock issued, outstanding and entitled to vote are required to be present in person or to be represented by proxy at the meeting in order to constitute a quorum for the transaction of business. The election of a nominee for director will be decided by plurality vote. Votes may be cast for or withheld from each nominee. The proposal to amend the 1997 Plan requires the affirmative vote of a majority of voting shares present in person or represented by proxy at the meeting (following the

determination of a quorum). The proposal to amend the Article of Organization to increase the number of authorized shares of Common Stock requires the affirmative vote of a majority of the shares of Common Stock outstanding and entitled to vote at the meeting. Both abstentions and broker “non-votes” (that is, shares held by a broker or nominee that does not have the authority, either express or discretionary, to vote on a particular matter) are counted as present for the purposes of determining the existence of a quorum for the transaction of business. However, for purposes of determining the number of shares voting on a particular proposal, abstentions and broker “non-votes” are not counted as votes cast or shares voting, and with respect to the proposal regarding the amendment to the Articles of Organization, will have the effect of a vote against such proposal.

RECORD DATE AND VOTING SECURITIES

Only shareholders of record at the close of business on September 17, 2004 are entitled to notice of and to vote at the meeting. At the close of business on that date, there were 21,044,957 shares of Common Stock outstanding and entitled to vote. Each outstanding share of the Corporation’s Common Stock entitles the record holder to cast one (1) vote for each matter to be voted upon.

PROPOSAL 1: ELECTION OF CLASS I DIRECTORS

Pursuant to Massachusetts law, the Corporation’s Board of Directors is divided into three (3) classes, with each class as nearly equal in number as possible. Presently, the Board of Directors consists of eight (8) members, with Dr. Albert P. Belle Isle, Lee C. Steele and Dr. Richard P. Wishner serving as Class I directors; Dr. Gordon B. Baty, George W. Chamillard and Sherman N. Mullin serving as Class II directors; and James R. Bertelli and Russell K. Johnsen serving as Class III directors.

The terms of the Class I, Class II and Class III directors expire in 2004, 2005 and 2006, respectively. Following expiration of its respective current term, each class is then nominated for election for a subsequent three-year term. It is proposed that the Class I nominees listed below, whose terms expire at this meeting, be elected to serve terms of three (3) years and in each case until their successors are duly elected and qualified or until they sooner die, resign or are removed.

Board of Directors Meetings and Directors’ Compensation

During fiscal year 2004, there were ten (10) meetings of the Board of Directors of the Corporation. The Board of Directors schedules executive sessions at each regular meeting of the Board, in which the Corporation’s independent directors meet without management present. The Board has established the role of Lead Independent Director, and Mr. Johnsen currently serves in that role, which includes chairing meetings of the independent directors. During fiscal year 2004, there were six (6) meetings of the Audit Committee, eleven (11) meetings of the Compensation Committee, and three (3) meetings of the Nominating and Governance Committee. All of the directors attended during fiscal year 2004 at least seventy-five percent (75%) of the aggregate of (a) the total number of meetings of the Board of Directors (held during the periods they were directors) and (b) the total number of meetings held by committees of the Board of Directors on which they served (during the periods they served).

Members of the Corporation’s Board of Directors are strongly encouraged to attend the Annual Meeting of Shareholders of the Corporation, or Special Meeting in lieu thereof; however, the Corporation does not have a formal policy with respect to attendance at the Annual or Special Meeting.

Each director who was not an employee of the Corporation received cash compensation in the amount of $12,500 for the fiscal year, paid in quarterly installments, plus an additional $2,500 for each meeting attended, as well as reimbursement for reasonable expenses incurred in connection with attendance at Board and committee meetings. In addition, committee members and the committee chairmen received an annual retainer of $1,500 and $2,500, respectively, as well as an additional $300 for attending any meeting not held on the same day as a meeting of the Board of Directors. The cash compensation paid to the current directors in their capacity as such during fiscal year 2004 was as follows:


Director	Cash Compensation
Dr. Gordon B. Baty	$	47,100
Dr. Albert P. Belle Isle	$	52,100
George W. Chamillard	$	8,125
Russell K. Johnsen	$	52,000
Sherman N. Mullin	$	47,400
Lee C. Steele	$	49,600
Dr. Richard P. Wishner	$	44,900

In addition to cash compensation, directors are also granted options pursuant to the 1997 Stock Option Plan. During fiscal year 2004, Drs. Baty and Belle Isle and Messrs. Johnsen and Mullin each were granted an option to purchase 6,000 shares at an exercise price of $19.03 per share. In addition, Mr. Chamillard was granted an option to purchase 15,000 shares at an exercise price of $24.28 per share. Mr. Steele and Dr. Wishner were not granted any options during fiscal year 2004.

Committees of the Board of Directors

The Board of Directors has a standing Audit Committee, Compensation Committee and Nominating and Governance Committee.

The members of the Audit Committee during fiscal year 2004 were Dr. Baty (Chairman), Dr. Belle Isle, Mr. Johnsen and Mr. Steele. The Audit Committee oversees management’s conduct of the Corporation’s financial reporting process, including by overviewing the financial reports and other financial information provided by the Corporation’s systems of internal accounting and financial controls, and the annual independent audit of the Corporation’s financial statements. The Audit Committee also reviews the scope of the Corporation’s engagement of its independent public auditors, preapproves all audit and non-audit services provided by the auditors and related fees, and discusses with management and the auditors the quality and adequacy of the Corporation’s internal accounting controls. Each member of the Audit Committee is “independent” as such term is defined in the applicable listing standards of NASDAQ and under the rules of the Securities and Exchange Commission (the “SEC”). The Board of Directors has also determined that Mr. Steele qualifies as an “audit committee financial expert” under SEC rules. The Audit Committee acts under a written charter, which was amended and restated in February 2004, a copy of which is attached to this proxy statement as Appendix A.

The Compensation Committee is currently comprised of Mr. Mullin (Chairman), Mr. Chamillard, Mr. Johnsen and Dr. Wishner, each of whom qualifies as an independent director as defined by NASDAQ. The Compensation Committee is responsible for administering the Corporation’s stock option plans, reviewing and approving the senior management compensation policy, and annually recommending to the Board the compensation of the Chief Executive Officer. The Compensation Committee acts pursuant to a written charter, which was adopted by the Board of Directors on February 4, 2004. A copy of the charter can be found on the Corporation’s website at www.mc.com on the Investor Relations page under “Corporate Governance.”

The members of the Nominating and Governance Committee are Dr. Belle Isle (Chairman), Dr. Baty and Mr. Mullin, each of whom qualifies as an independent director as defined by NASDAQ. The Nominating and Governance Committee recommends nominees to the Board of Directors, and has recommended the nominees for election at the meeting. The Nominating and Governance Committee acts pursuant to a written charter, which was adopted by the Board of Directors on February 4, 2004. A copy of the charter can be found on the Corporation’s website at www.mc.com on the Investor Relations page under “Corporate Governance.” The Nominating and Governance Committee will consider nominees recommended by shareholders if the shareholder submits the nomination in compliance with applicable requirements. The Nominating and Governance Committee did not receive any shareholder nominations for election of directors at this year’s meeting.

When considering a potential candidate for membership on the Board of Directors, the Nominating and Governance Committee will consider any criteria it deems appropriate, including, among other things, the experience and qualifications of any particular candidate as well as such candidate’s past or anticipated contributions to the Board and its committees. At a minimum, each nominee is expected to have high personal and professional integrity and demonstrated ability and judgment, and to be effective, with the other directors, in collectively serving the long-term interests of the shareholders. In addition to the minimum qualifications set forth for each nominee above, when considering potential candidates for the Board of Directors, the Nominating and Governance Committee seeks to ensure that the Board of Directors is comprised of a majority of independent directors and that the committees of the Board of Directors are comprised entirely of independent directors. The Nominating and Governance Committee may also consider any other standards that it deems appropriate, including whether a potential candidate has direct experience in the industry in which the Corporation operates and whether such candidate, if elected, would assist in achieving a mix of directors that represents a diversity of background and experience. In practice, the Nominating and Governance Committee generally will evaluate and consider all candidates recommended by the directors, officers and shareholders of the Corporation. The Nominating and Governance Committee intends to consider shareholder recommendations for directors using the same criteria as potential nominees recommended by the members of the committee or others.

Shareholders who wish to submit director candidates for consideration should send such recommendations to the Secretary of the Corporation at the Corporation’s executive offices not less than 120 calendar days prior to the date on which the Corporation’s proxy statement for the prior year was released. Such recommendations must include: (1) the name and address of record of the shareholder; (2) a representation that the shareholder is a record holder of the Corporation’s Common Stock, or if the shareholder is not a record holder, evidence of ownership in accordance with Rule 14a-8(b)(2) of the Exchange Act; (3) the name, age, business and residential address, educational background, current principal occupation or employment, and principal occupation or employment for the preceding five (5) full fiscal years of the proposed director candidate; (4) a description of the qualifications of the proposed director candidate which address the minimum qualifications described above; (5) a description of all arrangements or understandings between the shareholder and the proposed director candidate; and (6) the consent of the proposed director candidate to be named in the proxy statement and to serve as a director if elected at such meeting. Shareholders must also submit any other information regarding the proposed candidate that is required to be included in a proxy statement filed pursuant to the rules of the SEC. See also the information under “Deadlines for Submission of Shareholder Proposals.”

Communicating with Directors

Shareholders who wish to communicate with the Board of Directors or with a particular director may send a letter to the Secretary of Mercury Computer Systems, Inc. at 199 Riverneck Road, Chelmsford, Massachusetts 01824. The mailing envelope should contain a clear notation indicating that the enclosed letter is a “Shareholder-Board Communication” or “Shareholder-Director Communication.” All such letters should clearly state whether the intended recipients are all members of the Board or certain specified individual directors. The Secretary will make copies of all such letters and circulate them to the appropriate director or directors.

Code of Business Conduct and Ethics

The Corporation has adopted a Code of Business Conduct and Ethics applicable to its officers, directors and employees. This Code of Business Conduct and Ethics is posted on the Corporation’s website at www.mc.com on the Investor Relations page under “Corporate Governance.” The Corporation intends to satisfy its disclosure requirements regarding any amendment to, or waiver of, a provision of its Code of Business Conduct and Ethics by disclosing such matters on its website. Shareholders may request a copy of the Corporation’s Code of Business Conduct and Ethics free of charge by writing to the Secretary of Mercury Computer Systems, Inc. at 199 Riverneck Road, Chelmsford, Massachusetts 01824.

PROPOSAL 2: AMENDMENT TO 1997 STOCK OPTION PLAN TO INCREASE THE NUMBER OF SHARES AUTHORIZED FOR ISSUANCE THEREUNDER

There will be presented at the meeting a proposal to approve an amendment to the Corporation’s 1997 Stock Option Plan, which amendment was approved by the Board of Directors on August 24, 2004. The amendment provides for the number of shares of Common Stock authorized for issuance under the 1997 Plan to be increased from 7,650,000 shares to 8,650,000 shares. As of August 31, 2004, options for the purchase of 4,965,617 shares of Common Stock were outstanding under the 1997 Plan.

Recommendation

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE AMENDMENT TO THE 1997 PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE THEREUNDER BY 1,000,000 SHARES.

Introduction to the 1997 Plan

The 1997 Plan provides for the granting of incentive stock options meeting the requirements of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), non-qualified options which are not intended to meet the requirements of the Code, and restricted stock awards.

The 1997 Plan is intended to encourage ownership of the stock of the Corporation by employees of, and other key individuals engaged to provide services to, the Corporation and its subsidiaries, including directors, to induce qualified personnel to enter and remain in the employ of, or otherwise provide services to, the Corporation or its subsidiaries, and to provide additional incentive for grantees to promote the success of the Corporation’s business. The 1997 Plan is administered by the Compensation Committee, which consists of two (2) or more members of the Corporation’s Board of Directors. The members of the Compensation Committee are appointed by the Board of Directors and the Board may from time to time appoint a member or members of the Compensation Committee in substitution for or in addition to the member or members then in office, and may fill vacancies on the Compensation Committee, however caused. The present members of the Compensation Committee are Sherman N. Mullin (Chairman), George W. Chamillard, Russell K. Johnsen and Dr. Richard P. Wishner, c/o Mercury Computer Systems, Inc., 199 Riverneck Road, Chelmsford, Massachusetts 01824.

Summary of Amendment to the 1997 Plan

The Board of Directors believes that the remaining number of shares of Common Stock is not sufficient for future granting needs under the 1997 Plan. Accordingly, the proposed amendment to the 1997 Plan increases the number of shares of Common Stock authorized for issuance under the 1997 Plan from 7,650,000 shares to 8,650,000 shares. Based solely on the closing price of the Corporation’s Common Stock as reported on The NASDAQ National Market on September , 2004 of $ per share, the maximum aggregate market value of the additional 1,000,000 shares of Common Stock authorized for issuance under the 1997 Plan would be $ . The Board of Directors believes that these additional shares would result in an adequate number of shares of Common Stock being available for grant under the 1997 Plan.

The maximum number of shares of the Corporation’s Common Stock for which options may be granted under the 1997 Plan is subject to adjustments for capital changes. Shares issued under the 1997 Plan will be authorized but unissued shares of Common Stock. As of August 31, 2004, options for the purchase of 4,965,617

shares of Common Stock were outstanding under the 1997 Plan and 1,290,163 shares were available for new grants under the 1997 Plan. The maximum number of shares of the Corporation’s Common Stock that may be issued in the form of restricted stock under the 1997 Plan is 100,000 shares in the aggregate.

Summary of Other Principal Provisions of the 1997 Plan

Set forth below is a summary of other principal provisions of the 1997 Plan, a copy of which, together with the proposed amendment, may be obtained from the Secretary of the Corporation upon request. The affirmative vote of the holders of at least a majority of the shares of Common Stock voting in person or by proxy at the meeting will be required for approval of the amendment to the 1997 Plan.

Options. The 1997 Plan provides that options designated as incentive stock options may be granted only to employees (including officers and directors who are also employees) of the Corporation or any subsidiary. Options designated as non-qualified options may be granted to officers, directors, employees, consultants and advisors of the Corporation or any of its subsidiaries.

In determining the eligibility of an individual to be granted an option, as well as in determining the number of options to be granted to any individual, the Compensation Committee takes into account the position and responsibilities of the individual being considered, the nature and value to the Corporation or its subsidiaries of the individual’s service and accomplishments, his or her present and potential contribution to the success of the Corporation or its subsidiaries, and such other factors as the Compensation Committee deems relevant. The number of individuals potentially eligible to participate in the 1997 Plan is approximately 486 people.

To satisfy Section 162(m) of the Code, the maximum number of shares with respect to which an option or options may be granted to any employee in any one (1) taxable year of the Corporation shall not exceed 200,000, taking into account shares granted during such taxable period under options that have terminated.

Terms and Provisions of Options. Options granted under the 1997 Plan are exercisable at such times and during such period as is set forth in the option agreement, but no option granted under the 1997 Plan can have a term in excess of ten (10) years from the date of grant. The option agreement may contain such provisions and conditions as may be determined by the Compensation Committee. The option exercise price for options designated as non-qualified stock options granted under the 1997 Plan is determined by the Compensation Committee, but in no event shall be less than 100% of the fair market value of the underlying Common Stock at the time such option is granted. The option exercise price for incentive stock options granted under the 1997 Plan shall be no less than 100% of the fair market value of the Common Stock of the Corporation at the time the option is granted. Options granted under the 1997 Plan may provide for the payment of the exercise price by delivery of cash or shares of Common Stock of the Corporation owned by the optionee having a fair market value equal in amount to the exercise price of the options being exercised, or any combination thereof; provided, however, that the payment of the exercise price by delivery of shares of Common Stock of the Corporation owned by the optionee may be made only if the payment does not result in a charge to earnings for financial accounting purposes, as determined by the Compensation Committee.

The right of any optionee to exercise an option granted under the 1997 Plan is not assignable or transferable by such optionee otherwise than by will or the laws of descent and distribution, and any such option shall be exercisable during the lifetime of such optionee only by him or her; provided, however, that in the case of a non-qualified stock option, the Compensation Committee may permit transferability of such option on such terms and conditions as determined by the Compensation Committee and set forth in an option agreement.

An option granted to any employee optionee who ceases to be an employee of the Corporation or one of its subsidiaries shall terminate ninety (90) days after the date such optionee ceases to be an employee of the Corporation or one of its subsidiaries. If such termination of employment is because of dismissal for cause or because the employee is in breach of any employment agreement, such an option will terminate immediately on the date the optionee ceases to be an employee of the Corporation or one of its subsidiaries. If such termination of employment is because the optionee has become permanently disabled, the option shall terminate on the last day of the twelfth month from the date such optionee ceases to be an employee. In the event of the death of the optionee, the option shall terminate on the last day of the twelfth month from the date of death. If such termination of employment is because of the retirement of the optionee on or after attaining the minimum age, completing the minimum number of years of service and satisfying all other conditions specified for retirement status under the Corporation’s Retirement Policy Statement as in effect at the time of the grant of the option, such option will terminate on the date that is five (5) years after the date the optionee ceases to be an employee of the Corporation or one of its subsidiaries. An option granted to a non-employee director, a consultant or any other person who is not an employee of the Corporation or one of its subsidiaries shall be exercisable only to the extent so provided in the optionee’s agreement. In no event shall an option be exercisable after the date upon which it expires by its terms. The Compensation Committee has the authority to extend the expiration date of any outstanding option in circumstances in which it deems such action to be appropriate.

An option granted to an employee optionee who ceases to be an employee of the Corporation or one of its subsidiaries shall be exercisable only to the extent that the right to purchase shares under such option has accrued and is in effect on the date such optionee ceases to be an employee of the Corporation or one of its subsidiaries. In the event of the death of any optionee, the option granted to such optionee may be exercised by the estate of such optionee, or by any person or persons who acquired the right to exercise such option by bequest or inheritance or by reason of the death of such optionee.

Restricted Stock Awards. The Compensation Committee may also award shares of common stock subject to such conditions and restrictions as the Compensation Committee may determine as set forth in a restricted stock award agreement. These conditions and restrictions may include the achievement of pre-established performance goals and/or continued employment with the Corporation through a specified vesting period. The vesting period shall be determined by the Compensation Committee; provided, however, that in the case of any performance-based goals, the vesting period will not be less than one (1) year, and in the case of any continued employment requirements, the vesting period will not be less than three (3) years. If the applicable performance goals and other restrictions are not attained, the participant will forfeit his award of restricted stock. The purchase price (if any) of shares of restricted stock will be determined by the Compensation Committee.

Recapitalization; Reorganization; Change of Control. The 1997 Plan provides that the number and kind of shares as to which options or shares of restricted stock may be granted thereunder and as to which outstanding options then unexercised shall be exercisable shall be adjusted to prevent dilution in the event of any reorganization, merger, consolidation, recapitalization, reclassification, stock split-up, combination of shares or dividends payable in capital stock. In addition, unless otherwise determined by the Compensation Committee in its sole discretion, in the case of any sale or conveyance to another entity of all or substantially all of the property and assets of the Corporation or a Change of Control (as defined in the 1997 Plan), the purchaser of the Corporation’s assets or stock may deliver to the optionee or holder of restricted stock the same kind of consideration that is delivered to the shareholders of the Corporation as a result of the sale, conveyance or Change of Control or the Compensation Committee may cancel all outstanding options or shares of restricted stock in exchange for consideration in cash or in kind, which consideration shall be equal in value to the value of

those shares of stock or other securities the optionee would have received had the option been exercised (to the extent then exercisable) and no disposition of the shares acquired upon such exercise has been made prior to such sale, conveyance or a Change of Control, less the option price therefor, or the value of those shares or other securities the holder of restricted stock would have received had the shares of restricted stock vested (to the extent they would have vested as of such date) and no disposition of the vested shares has been made prior to such sale, conveyance or a Change of Control.

The Compensation Committee shall also have the power to accelerate the exercisability or vesting of any options or shares of restricted stock, notwithstanding any limitations in the 1997 Plan or in the option or restricted stock agreement, upon such a sale, conveyance or Change of Control. A “Change of Control” is defined in the 1997 Plan as having occurred if any of the following conditions have occurred: (1) the merger or consolidation of the Corporation with another entity where the Corporation is not the surviving entity and where after the merger or consolidation (a) its shareholders prior to the merger or consolidation hold less than 50% of the voting stock of the surviving entity and (b) its directors prior to the merger or consolidation are less than a majority of the Board of the surviving entity; (2) the sale of all or substantially all of the Corporation’s assets to a third party and subsequent to the transaction (a) its shareholders hold less than 50% of the stock of said third party and (b) its directors are less than a majority of the board of said third party; (3) a transaction or series of related transactions, including a merger of the Corporation with another entity where the Corporation is the surviving entity, whereby 50% or more of the voting stock of the Corporation is transferred to parties who are not prior thereto shareholders or affiliates of the Corporation; or (4) the Continuing Directors shall not constitute a majority of the Board of Directors of the Corporation. The term “Continuing Directors” shall mean a member of the Board of Directors of the Corporation who either was a member of the Board of Directors of the Corporation on the date the 1997 Plan was adopted by the Board of Directors or who subsequently became a director of the Corporation and whose initial appointment, initial election or initial nomination for election by the Corporation’s shareholders subsequent to such date was approved by a vote of a majority of the Continuing Directors then on the Board of Directors of the Corporation. Upon dissolution or liquidation of the Corporation, all options and shares of restricted stock granted under the 1997 Plan shall terminate, but each optionee shall have the right, immediately prior to such dissolution or liquidation, to exercise his or her option to the extent then exercisable. The Compensation Committee shall have the right to accelerate the vesting of any award or take such other action with respect thereto as the Compensation Committee shall in its sole discretion determine in the event of any contemplated dissolution or liquidation of the Corporation.

Termination and Amendment. Unless sooner terminated, the 1997 Plan shall terminate ten (10) years from June 5, 1997, the date upon which it was adopted by the Board of Directors. The Board of Directors may at any time terminate the 1997 Plan or make such modification or amendment as it deems advisable; provided, however, that the Board of Directors may not, without shareholder approval, increase the maximum number of shares for which options and shares of restricted stock may be granted or change the designation of the class of persons eligible to receive options under the 1997 Plan or make any other change in the 1997 Plan which requires shareholder approval under applicable law or regulations. The Compensation Committee may terminate, amend or modify any outstanding option without the consent of the option holder; provided, however, that without the consent of the optionee, the Compensation Committee shall not change the number of shares subject to an option nor the exercise price thereof, nor extend the term of such option.

Tax Effects of Plan Participation

Options granted under the 1997 Plan are intended to be either incentive stock options, as defined in Section 422 of the Code, or non-qualified stock options.

Incentive Stock Options. Except as provided below with respect to the alternative minimum tax, the optionee will not recognize taxable income upon the grant or exercise of an incentive stock option. If the optionee holds the shares received pursuant to the exercise of the option for at least one (1) year after the date of exercise and for at least two (2) years after the option is granted, the optionee will recognize long-term capital gain or loss upon the disposition of the stock measured by the difference between the option exercise price (the stock’s basis) and the amount received for such shares upon disposition.

In the event that the optionee disposes of the stock prior to the expiration of the required holding periods (a “disqualifying disposition”), the optionee generally will realize ordinary income equal to the difference between the exercise price and the lower of the fair market value of the stock at the date of the option exercise or the sale price of the stock. The basis in the stock acquired upon exercise of the option will equal the amount of income recognized by the optionee plus the option exercise price. Upon eventual disposition of the stock, if the optionee holds the stock as a capital asset, the optionee will recognize long-term or short-term capital gain or loss, depending on the holding period of the stock and the difference between the amount realized by the optionee upon disposition of the stock and the optionee’s basis in the stock. Under current law, an optionee will not have any additional FICA (Social Security taxes) upon exercise of an incentive stock option.

For alternative minimum tax purposes, the excess of the fair market value of stock on the date of the exercise of the incentive stock option over the exercise price of the option is included in alternative minimum taxable income for alternative minimum tax purposes. If the alternative minimum tax applies to the optionee, an alternative minimum tax credit may reduce the regular tax upon eventual disposition of the stock.

The Corporation will not be allowed an income tax deduction upon the grant or exercise of an incentive stock option. However, upon a disqualifying disposition by the optionee of shares acquired upon exercise of the incentive stock option, the Corporation will be allowed a deduction in an amount equal to the ordinary income recognized by the optionee.

The Internal Revenue Service will treat the exercise of an option with previously acquired stock of the Corporation as, in effect, two (2) separate transactions. Pursuant to Section 1036 of the Code, the first transaction will be a tax-free exchange of the previously acquired shares for the same number of new shares. The new shares will retain the basis and the holding periods of the previously acquired shares. The second transaction will be the issuance of additional new shares having a value equal to the difference between the aggregate fair market value of all of the new shares being acquired and the aggregate option exercise price for those shares. Because the exercise of an incentive stock option does not result in the recognition by the optionee of income, this issuance will also be tax-free (unless the alternative minimum tax applies, as described above). The optionee’s basis in these additional new shares will be zero and the optionee’s holding period for these shares will commence on the date on which the shares are transferred. For purposes of the one and two-year holding period requirements that must be met for favorable incentive stock option tax treatment to apply, the holding periods of previously acquired shares are disregarded.

Non-qualified Stock Options. As in the case of incentive stock options, no income is recognized by the optionee on the grant of a non-qualified stock option. On the exercise by an optionee of a non-qualified option,

generally the excess of the fair market value of the stock when the option is exercised over its cost to the optionee will be (1) taxable to the optionee as ordinary income and (2) deductible for income tax purposes by the Corporation. The optionee’s tax basis in his or her stock will equal his or her cost for the stock plus the amount of ordinary income the optionee had to recognize with respect to the non-qualified stock option. Upon exercise, the optionee will also be subject to FICA (Social Security taxes) on the excess of the fair market value over the exercise price of the option.

The Internal Revenue Service will treat the exercise of a non-qualified stock option with previously acquired stock of the Corporation as two (2) transactions. First, there will be a tax-free exchange of the old shares for a like number of shares under Section 1036 of the Code, with such exchanged shares retaining the basis and holding period of the old shares. Second, there will be an issuance of additional new shares having a value equal to the difference between the fair market value of all new shares being acquired (including the exchanged shares and the additional new shares) and the aggregate option price for those shares. The employee will recognize ordinary income under Section 83 of the Code, in an amount equal to the fair market value of the additional new shares (that is, the spread on the option). The additional new shares will have a basis equal to the fair market value of the additional new shares and the optionee’s holding period for the additional new shares will commence on the date on which the shares are transferred.

If the optionee holds the stock as a capital asset, upon a subsequent disposition of stock acquired upon the exercise of a non-qualified stock option, the optionee will recognize short-term or long-term capital gain or loss, depending upon the holding period of the stock equal to the difference between the amount realized upon disposition of the stock by the optionee and the optionee’s basis in the stock.

Parachute Payments. The vesting of any portion of any award that is accelerated due to the occurrence of a change of control may cause a portion of the payments with respect to such accelerated award to be treated as “parachute payments” as defined in the Code. Any such parachute payments may be non-deductible to the Corporation, in whole or in part, and may subject the recipient to a non-deductible 20% Federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Limitation on Corporation’s Deductions. As a result of Section 162(m) of the Code, the Corporation’s Federal tax deduction for certain awards under the 1997 Plan may be limited to the extent that the Chief Executive Officer or other executive officer whose compensation is required to be reported in the summary compensation table receives compensation (other than performance-based compensation) in excess of $1,000,000 a year.

PROPOSAL 3: AMENDMENT TO ARTICLES OF ORGANIZATION TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE THEREUNDER

General

At present, the Corporation’s Articles of Organization authorize the issuance of up to 65,000,000 shares of Common Stock and 1,000,000 shares of preferred stock, par value $.01 per share. As of August 31, 2004, 21,014,045 shares of Common Stock were issued and outstanding. In addition, 4,965,617 shares of Common Stock were reserved for issuance upon exercise of options outstanding under the Corporation’s stock option plans, 1,480,268 shares of Common Stock were reserved for future issuance under the Corporation’s stock option plans and employee stock purchase plan, 257,511 shares of Common Stock were reserved for issuance in connection with a recent acquisition by the Corporation, and 4,134,962 shares of Common Stock were reserved for issuance upon conversion of the Corporation’s 2.00% convertible senior notes due 2024. Accordingly, as of August 31, 2004, there were 33,147,597 shares of Common Stock available for general corporate purposes. If Proposal 2 is approved by shareholders, an additional 1,000,000 shares will be reserved for future issuance under the 1997 Plan, thereby reducing the number of shares available to 32,147,597. No shares of preferred stock have been issued.

On August 24, 2004, the Board of Directors of the Corporation determined that it would be in the best interests of the Corporation and its shareholders to amend the Articles of Organization to increase the number of authorized shares of Common Stock from 65,000,000 to 85,000,000 shares. The proposed amendment will not affect the authorized number of shares of preferred stock. The Board also directed that the proposed amendment be submitted for action at the meeting.

Under the proposed amendment, Article 4.A of the Corporation’s Articles of Organization would be amended in its entirety to read as follows:

“The aggregate number of shares which this Corporation shall have authority to issue is: 85,000,000 shares of common stock having a par value of $.01 per share (the “Common Stock”) and 1,000,000 shares of preferred stock having a par value of $.01 per share (the “Preferred Stock”).”

The affirmative vote of the holders of a majority of the outstanding shares of Common Stock entitled to vote at the meeting is required for approval of the amendment to the Articles of Organization.

Recommendation

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE AMENDMENT TO THE ARTICLES OF ORGANIZATION TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE THEREUNDER BY 20,000,000 SHARES.

Purpose of the Proposed Amendment

The Board of Directors believes that the availability of additional authorized but unissued shares will provide the Corporation with greater flexibility to issue Common Stock for a variety of corporate purposes, without the delay and expense associated with convening a special meeting of shareholders. These purposes may include, without limitation, effecting future stock splits in the form of stock dividends, raising equity capital or acquiring businesses and assets.

Other than shares currently reserved for issuance, as indicated above, the Board of Directors has not authorized the issuance of any additional shares of Common Stock, and there are no current agreements or commitments for the issuance of additional shares. The Corporation, however, may acquire companies as part of its strategy to broaden and strengthen its business. Such acquisitions have in the past and may in the future involve payment with shares of Common Stock. Therefore, the Board of Directors believes that the proposed increase in the number of authorized shares of Common Stock is desirable to maintain the Corporation’s flexibility in choosing how to structure future acquisitions and in considering and implementing any of the other corporate transactions described above.

Possible Effects of the Proposed Amendment

If the shareholders approve the proposed amendment, the Board of Directors may cause the issuance of additional shares of Common Stock without further vote of the shareholders of the Corporation, except as provided under Massachusetts corporate law or under the rules of any national securities exchange or quotation system on which shares of Common Stock are then listed. Under the Articles of Organization, the Corporation’s shareholders do not have preemptive rights to subscribe to additional securities which may be issued by the Corporation, which means that current shareholders do not have a prior right to purchase any new issue of stock of the Corporation in order to maintain their proportionate ownership of the Corporation’s Common Stock. In addition, if the Board of Directors elects to issue additional shares of Common Stock, such issuance could have a dilutive effect on the earnings per share, voting power and holdings of current shareholders.

In addition to the corporate purposes discussed above, the proposed amendment could, under certain circumstances, have an anti-takeover effect, although this is not the intent of the Board of Directors. For example, it may be possible for the Board of Directors to delay or impede a takeover or transfer of control of the Corporation by causing such additional authorized shares to be issued to holders who might side with the Board in opposing a takeover bid that the Board determines is not in the best interests of the Corporation and its shareholders. The amendment therefore may have the effect of discouraging unsolicited takeover attempts. By potentially discouraging initiation of any such unsolicited takeover attempt, the proposed amendment may limit the opportunity for the Corporation’s shareholders to dispose of their shares at the higher price generally available in takeover attempts or that may be available under a merger proposal. However, the Board of Directors is not aware of any attempt to take control of the Corporation and the Board of Directors has not presented this proposal with the intent that it be utilized as a type of anti-takeover device.

PRINCIPAL HOLDERS OF VOTING SECURITIES

The following table shows any person who is known by the Corporation to be the beneficial owner of more than five percent (5%) of the outstanding Common Stock of the Corporation.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

The Compensation Committee of the Board of Directors has furnished the following report on executive compensation.

The Compensation Committee administers the Corporation’s stock option plans, makes annual recommendations to the full Board of Directors regarding the Chief Executive Officer’s salary, bonus, and equity-based compensation, and oversees the executive compensation program for the Corporation’s other employees, including its executive officers. During fiscal year 2004, the Compensation Committee was composed of independent directors who were not employees of the Corporation.

Compensation Philosophy

The Corporation’s compensation policies for executive officers are based on the belief that the interests of executives should be closely aligned with those of the Corporation’s shareholders. The compensation policies are designed to achieve the following objectives:

•

Offer compensation opportunities that attract highly qualified executives, reward exceptional initiative and achievement, and retain the leadership and skills necessary to build long-term shareholder value.

•

Maintain a significant portion of executives’ total compensation at risk, tied to both the annual and long-term financial performance of the Corporation and the creation of shareholder value.

•

Further the Corporation’s short-term and long-term strategic goals and values by aligning compensation with business objectives and individual performance.

Executive Compensation

Compensation of executive officers other than the Chief Executive Officer is recommended by the Chief Executive Officer and is subject to approval by the Compensation Committee. The Compensation Committee historically has obtained outside survey data regarding executive and senior level compensation and provided this data to the Chief Executive Officer to assist him in making compensation recommendations. Compensation for executive officers is comprised of base salary, annual cash bonuses and periodic stock option grants.

Base salary. Annual determinations of base salaries are made based in part on the competitive pay practices of companies in the same industry of similar size and market capitalization, the skills, performance level, and contribution to the business of the individual executives, and the needs of the Corporation.

Annual cash incentive awards. The Corporation’s executive officers are eligible to receive annual cash bonus awards designed to motivate executives to attain short-term and longer-term corporate and individual

management goals. Award levels vary depending upon the achievement of performance criteria established by the Chief Executive Officer. The bonus criteria for each executive officer are tailored to the achievement of financial and operational goals specifically developed for that officer’s area of responsibility, as well as overall corporate performance and the attainment of other individual objectives. Consequently, there is a direct link between the compensation of the executive officers and the Corporation’s performance.

Industry benchmark bonus. When the Corporation’s results exceed the performance of the 50th percentile of the high-tech universe of the Russell 2000 Index, an add-on is applied to the executive officers’ compensation. In calculating this bonus, the Corporation’s performance is based on revenue growth, profit before taxes and profit before tax as a percentage of sales.

Long-term incentive. The Compensation Committee believes that stock options are an excellent vehicle for compensating its officers and employees. The Corporation provides long-term incentives through its stock option and stock purchase plans, a purpose of which is to create a direct link between executive compensation and increases in shareholder value. Stock options are granted at fair market value and vest in installments, generally over four (4) years. When determining option awards for an executive officer, the Compensation Committee considers the executive’s current contribution to the Corporation’s performance, the anticipated contribution to meeting the Corporation’s long-term strategic performance goals and industry practices and norms. Long-term incentives granted in prior years and existing levels of stock ownership are also taken into consideration. Because the receipt of value by an executive officer under a stock option is dependent upon an increase in the price of the Corporation’s Common Stock, this portion of the executive’s compensation is directly aligned with an increase in shareholder value.

Deferred compensation plan. An executive non-qualified deferred compensation plan was established during fiscal 2001. In accordance with the deferred compensation plan, executives of the Corporation may elect to contribute up to 35% of their total compensation in a deferral account.

Compensation of Chief Executive Officer. The Chief Executive Officer’s compensation is comprised of base salary, annual cash incentive awards and stock option grants. In determining the base salary paid to Mr. Bertelli for the year ended June 30, 2004, the Compensation Committee considered his level of responsibility, salary increases awarded to him in the past, his experience, his potential, and compensation programs of other companies of similar size and characteristics. Mr. Bertelli’s aggregate base salary for fiscal 2004 was $387,986, which represented an increase of approximately 6.5% over his aggregate base salary for the prior year. This increase is the result of the full year effect of a raise given in October 2002. There was no salary increase for Mr. Bertelli in fiscal year 2004.

Annual cash bonuses to Mr. Bertelli are based on the attainment of individual and corporate performance targets established at the beginning of the fiscal year. Mr. Bertelli has received a cash bonus of $229,053 with respect to the year ended June 30, 2004 in recognition of his achievement of certain goals. Mr. Bertelli may receive additional bonus amounts, including up to $114,277 if the Corporation’s results exceed the performance of the 50^th percentile of the high-tech universe of the Russell 2000 Index, which amounts could not be determined as of the date of this proxy statement. Set forth below under the heading “Option Grants, Exercises and Holdings” in the section of this proxy statement entitled “Executive Compensation” are the options granted to Mr. Bertelli during the year ended June 30, 2004, as well as options granted subsequent to the close of fiscal year 2004.

Tax deductibility of compensation. In 1993, the Internal Revenue Code was amended to limit the deduction a public company is permitted for compensation paid to the Chief Executive Officer and to the four most highly compensated executive officers, other than the Chief Executive Officer. Generally, amounts paid in

excess of $1,000,000 to a covered executive cannot be deducted, unless the compensation is paid pursuant to a plan which is performance related, non-discretionary and has been approved by the Corporation’s shareholders. In its deliberations, the Compensation Committee considers ways to maximize deductibility of executive compensation, but nonetheless retains the discretion to compensate executive officers at levels the Compensation Committee considers commensurate with their responsibilities and achievements. The Corporation has not adopted a policy that all executive compensation be fully deductible.

AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

Report of the Audit Committee

The following is the report of the Audit Committee of the Board of Directors of the Corporation with respect to the Corporation’s audited financial statements for the fiscal year ended June 30, 2004. Management is responsible for the Corporation’s internal controls and financial reporting process. The Corporation’s independent auditors are responsible for performing an independent audit of the Corporation’s financial statements in accordance with generally accepted auditing standards and issuing a report on those financial statements. The Audit Committee is responsible for monitoring and overseeing these processes.

The Audit Committee reviewed the Corporation’s audited financial statements for the fiscal year ended June 30, 2004, and discussed these financial statements with the Corporation’s management. Management represented to the Audit Committee that the Corporation’s financial statements had been prepared in accordance with generally accepted accounting principles. The Audit Committee also reviewed and discussed the audited financial statements and the matters required to be discussed by Statement of Auditing Standards No. 61, as amended (Communication with Audit Committees), with the Corporation’s independent registered public accounting firm. That Statement of Accounting Standards requires the auditors to ensure that the Audit Committee received information regarding the scope and results of the audit. The Audit Committee received the letter from the independent auditors required by Independence Standards Board Standard No. 1, and has discussed with the independent auditors their independence.

Based on its review and the discussions with management and the independent auditors described above, and its review of the representations and information provided by management and the independent auditors, the Audit Committee recommended to the Corporation’s Board of Directors that the audited financial statements be included in the Corporation’s Annual Report on Form 10-K for the fiscal year ended June 30, 2004.

Fees

Management has advised the Audit Committee that aggregate fees for professional services rendered for the Corporation by PricewaterhouseCoopers LLP for the fiscal years ended June 30, 2004 and 2003 were as follows:


	2004		2003
Audit	$	649,000	$	395,000
Audit-Related		221,000		65,000
Tax		65,000		140,000
All Other		1,000		1,000

	$	936,000	$	601,000

Audit fees for the years ended June 30, 2004 and 2003 were for professional services rendered for the audit of the Corporation’s consolidated financial statements, statutory audits, reviews of the financial statements included in each of the Corporation’s Quarterly Reports on Form 10-Q and providing comfort letters in connection with securities underwritings.

Audit-related fees for the fiscal years ended June 30, 2004 and 2003 were for due diligence services related to mergers and acquisitions, accounting consultations in connection with acquisitions, and consultations concerning financial accounting and reporting standards.

Tax fees for the fiscal years ended June 30, 2004 and 2003 were for services related to tax compliance, planning and advice, including tax return preparation or review and assistance with tax audits.

All other fees for the fiscal years ended June 30, 2004 and 2003 were for a license fee.

Pre-approval Policies

The Audit Committee pre-approves all auditing services and the terms of such services (which may include providing comfort letters in connection with securities underwritings) and non-audit services provided by the Corporation’s independent auditors, but only to the extent that the non-audit services are not prohibited under applicable law and the Audit Committee reasonably determines that the non-audit services do not impair the independence of the independent auditors. The authority to pre-approve non-audit services may be delegated to one or more members of the Audit Committee, who present all decisions to pre-approve an activity to the full Audit Committee at its first meeting following such decision.

The pre-approval requirement is waived with respect to the provision of non-audit services for the Corporation if (1) the aggregate amount of all such non-audit services provided to the Corporation constitutes not more than five percent (5%) of the total amount of fees paid by the Corporation to its independent auditors during the fiscal year in which such non-audit services were provided, (2) such services were not recognized at the time of the engagement to be non-audit services, and (3) such services are promptly brought to the attention of the Audit Committee and approved prior to the completion of the audit by the Audit Committee or by one or more of its members to whom authority to grant such approvals has been delegated by the Audit Committee.

The Audit Committee has considered and determined that the provision of the non-audit services described is compatible with maintaining the auditor’s independence.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed PricewaterhouseCoopers LLP as independent auditors to examine the consolidated financial statements of the Corporation and its subsidiaries for the fiscal year ended June 30, 2005. A representative of PricewaterhouseCoopers LLP is expected to be present at the meeting and will have the opportunity to make a statement if he or she so desires and to respond to appropriate questions.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires the Corporation’s officers and directors and persons beneficially owning more than 10% of the outstanding Common Stock of the Corporation to file reports of beneficial ownership and changes in beneficial ownership with the SEC. Officers, directors and beneficial owners of greater than 10% of the Corporation’s Common Stock are required by SEC regulation to furnish the Corporation with copies of all Section 16(a) forms they file.

Based solely on copies of such forms furnished as provided above, or written representations that no Forms 5 were required, the Corporation believes that during the fiscal year ended June 30, 2004 all Section 16(a) filing requirements applicable to its officers, directors and beneficial owners of greater than 10% of its Common Stock were complied with.

DEADLINES FOR SUBMISSION OF SHAREHOLDER PROPOSALS

Under regulations adopted by the SEC, any proposal submitted for inclusion in the Corporation’s proxy statement relating to the Annual Meeting of Shareholders to be held in 2005 must be received at the Corporation’s principal executive offices in Chelmsford, Massachusetts on or before June , 2005. Receipt by the Corporation of any such proposal from a qualified shareholder in a timely manner will not ensure its inclusion in the proxy material because there are other requirements in the proxy rules for such inclusion.

In addition to the SEC requirements regarding shareholder proposals, the Corporation’s By-Laws contain provisions regarding matters to be brought before shareholder meetings. If shareholder proposals, including proposals regarding the election of directors, are to be considered at the 2005 Annual Meeting of Shareholders, notice of them, whether or not they are included in the Corporation’s proxy statement and form of proxy, must be given by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation on or before August 6, 2005. The notice must include the information set forth in the Corporation’s By-Laws. Proxies solicited by the Board of Directors will confer discretionary voting authority with respect to these proposals subject to SEC rules governing the exercise of this authority.

It is suggested that any shareholder proposal be submitted by certified mail, return receipt requested.

OTHER MATTERS

Management knows of no matters which may properly be and are likely to be brought before the meeting other than the matters discussed herein. However, if any other matters properly come before the meeting, the persons named in the enclosed proxy will vote in accordance with their best judgment.

EXPENSES AND SOLICITATION

The cost of this solicitation of proxies will be borne by the Corporation. In addition to soliciting shareholders by mail through its regular employees, the Corporation may request banks, brokers, and other custodians, nominees and fiduciaries to solicit their customers who have stock of the Corporation registered in the names of a nominee, and, if so, will reimburse such banks, brokers and other custodians, nominees and fiduciaries for their reasonable out-of-pocket costs. Solicitation by officers and employees of the Corporation may also be made of some shareholders in person or by mail, telephone or telegraph following the original solicitation. In addition, the Corporation has retained D.F. King & Co., Inc. to assist in soliciting proxies and will pay fees estimated at $7,500, plus disbursements, in connection with the solicitation.

ANNUAL REPORT ON FORM 10-K

THE CORPORATION WILL PROVIDE EACH BENEFICIAL OWNER OF ITS SECURITIES WITH A COPY OF ITS ANNUAL REPORT ON FORM 10-K, INCLUDING THE FINANCIAL STATEMENTS AND SCHEDULES THERETO, REQUIRED TO BE FILED WITH THE SEC FOR THE CORPORATION’S MOST RECENT FISCAL YEAR, WITHOUT CHARGE, UPON RECEIPT OF A WRITTEN OR ORAL REQUEST FROM SUCH PERSON.

MERCURY COMPUTER SYSTEMS, INC.

AUDIT COMMITTEE CHARTER

PURPOSE

The primary purpose of the Audit Committee (the “Committee”) is to assist the Board of Directors (the “Board”) in fulfilling its responsibility to oversee (i) management’s conduct of the Company’s accounting and financial reporting processes, including by overviewing the financial reports and other financial information provided by the Company’s systems of internal accounting and financial controls, (ii) the annual independent audit of the Company’s financial statements, and (iii) the qualifications, independence and performance of the Company’s outside auditor.

In discharging its oversight role, the Committee is empowered to investigate any matter brought to its attention with full access to all books, records, facilities and personnel of the Company and the power to retain outside counsel, auditors or other experts for this purpose.

The Committee shall meet as often as it determines is appropriate to carry out its responsibilities under this Charter, but not less frequently than quarterly. The Committee may form and delegate authority to subcommittees consisting of one or more of its members as the Audit Committee deems appropriate to carry out its responsibilities and exercise its powers.

The Committee shall review and reassess the adequacy of this Charter on an annual basis.

MEMBERSHIP

The Committee shall be comprised of not less than three members of the Board. The members of the Committee shall meet the independence and experience requirements of applicable statutes and regulations, including the requirements of the Securities Exchange Act of 1934, as amended, and NASDAQ.

KEY RESPONSIBILITIES

The Committee’s job is one of oversight and it recognizes that the Company’s management is responsible for preparing the Company’s financial statements and that the outside auditors are responsible for auditing those financial statements. Additionally, the Committee recognizes that financial management, as well as the outside auditors, have more time, knowledge and more detailed information on the Company than do Committee members; consequently, in carrying out its oversight responsibilities, the Committee is not providing any expert or special assurance as to the Company’s financial statements or any professional certification as to the outside auditor’s work. In addition, it is not the duty of the Committee to conduct investigations or to assure compliance with laws and regulations or the Company’s Code of Business Conduct and Ethics.

A-1

The following functions shall be the common recurring activities of the Committee in carrying out its oversight function. These functions are set forth as a guide with the understanding that the Committee may diverge from this guide as appropriate given the circumstances.

•

The Committee shall review with management and the outside auditors the audited financial statements to be included in the Company’s Annual Report on Form 10-K (or the Annual Report to Shareholders if distributed prior to the filing of Form 10-K) and review and consider with the outside auditors the matters required to be discussed by Statement of Auditing Standards (“SAS”) No. 61, to assist the Committee in fulfilling its oversight responsibilities.

•

As a whole, or through the Committee chair, the Committee shall review with the outside auditors the matters (if any) required to be discussed by SAS No. 71 in connection with the interim financial reviews conducted by the outside auditors to assist the Committee in fulfilling its oversight responsibilities; this review will occur prior to the Company’s filing of the Form 10-Q.

•

The Committee shall receive from time to time the outside auditor reports concerning:

•

all critical accounting policies and practices to be used;

•

all alternative treatments of financial information within generally accepted accounting principles that have been discussed with management of the Company, ramifications of the use of such alternative disclosures and treatments, and the treatment preferred by the registered public accounting firm; and

•

other material written communications between the registered public accounting firm and the management of the Company, such as any management letter or schedule of unadjusted differences.

•

The Committee shall discuss with management and the outside auditors:

•

the accounting policies of the Company which may be viewed as critical; the nature and extent of any significant changes in accounting principles or the application thereof; significant judgment areas; significant risks and exposures and the steps management has taken to minimize such risks to the Company; and the quality and adequacy of the Company’s internal controls, accounting policies and estimates;

•

the terms and effects of any transactions with parties related to the Company which are significant in size or which involve terms or other aspects which differ from those which would likely be negotiated with an unaffiliated third party and which are material to an understanding of the Company’s financial statements; and

•

the nature of any off-balance sheet structures, including financing arrangements, and their potential impact on the Company and its financial statements.

•

The Committee shall:

•

request from the outside auditors annually, a formal written statement delineating all relationships between the auditor and the Company consistent with Independence Standards Board Standard Number 1;

•

discuss with the outside auditors any such disclosed relationships and their impact on the outside auditor’s independence;

•

take appropriate action to oversee the independence of the outside auditor; and

A-2

•

preapprove all auditing and non-audit services provided to the Company by the outside auditor. The Committee may delegate to one or more of its members the authority to grant such preapprovals. Preapprovals granted by any such delegate shall be presented to the full Committee at its next scheduled meeting.

•

establish procedures for:

•

the receipt, retention, and treatment of complaints received by the Company regarding accounting, internal accounting controls, or auditing matters; and

•

the confidential, anonymous submission by employees of the Company of concerns regarding questionable accounting or auditing matters.

•

The Committee shall be directly responsible for the appointment, compensation, retention and oversight of the work of the outside auditor (including resolution of disagreements between management and the outside auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or related work or performing other audit, review or attest services for the Company. The outside auditor shall report directly to the Committee.

•

The Committee will prepare the report required by the rules of the Securities and Exchange Commission to be included in the Company’s annual proxy statement.

•

Based on the criteria set forth in Item 306(a) of Regulation S-K (or any successor provision) and, if so determined by the Committee, recommend to the Board of Directors that the audited financial statements for each fiscal year be included in the Company’s Annual Report on Form 10-K in respect of such year.

•

The Committee shall conduct an appropriate review of all related party transactions for potential conflict of interest situations on an ongoing basis and the approval of the Committee shall be required for all related party transactions. The term related party transaction shall have the meaning ascribed to it for purposes of Rule 4350(h) of NASDAQ (or any successor rule).

•

The Committee shall have the authority to engage and determine financing for independent counsel and other advisers as it determines necessary to carry out its duties. The Committee shall have the authority to incur such ordinary administrative expenses as are necessary or appropriate in carrying out its duties.

•

The Committee will perform such other functions as may be required by law, the Company’s Articles of Organization or its By-Laws.

1997 STOCK OPTION PLAN

PURPOSE OF THE PLAN.

This stock option plan (the “Plan”) is intended to encourage ownership of the stock of Mercury Computer Systems, Inc. (the “Company”) by employees and advisors of the Company and its subsidiaries, to induce qualified personnel to enter and remain in the employ of the Company or its subsidiaries and otherwise to provide additional incentive for optionees to promote the success of its business.

STOCK SUBJECT TO THE PLAN.

(a) The maximum number of shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”) for which options or shares of restricted stock may be granted under this Plan shall be seven million six hundred fifty thousand (7,650,000) shares, provided that not more than 100,000 shares shall be issued in the form of restricted stock. The maximum number of shares of Common Stock available for granting incentive stock options under this Plan shall be seven million six hundred fifty thousand (7,650,000) shares. These limitations and all other limitations on the number of shares referenced in this Plan shall be subject to adjustment as provided in Section 12 of the Plan. Shares issued under the Plan may be authorized but unissued shares of Common Stock, or shares of Common Stock held in treasury by the Company.

(b) If an option or restricted stock award granted hereunder is forfeited, canceled, reacquired by the Company, satisfied without the issuance of shares of Common Stock or otherwise terminated (other than by exercise), the shares of Common Stock subject thereto shall again be available for subsequent option or restricted stock award grants under the Plan.

(c) Stock issuable upon exercise of an option granted under the Plan or the grant of a restricted stock award may be subject to such restrictions on transfer, repurchase rights or other restrictions as shall be determined by the Committee.

ADMINISTRATION OF THE PLAN.

The Plan shall be administered by a committee (the “Committee”) consisting of two or more members of the Company’s Board of Directors. The selection of persons for participation in the Plan and all decisions concerning the timing, pricing and amount of any grant or award under the Plan shall be made solely by the Committee. The Board of Directors may from time to time appoint a member or members of the Committee in substitution for or in addition to the member or members then in office and may fill vacancies on the Committee however caused. The Committee shall choose one of its members as Chairman and shall hold meetings at such times and places as it shall deem advisable. A majority of the members of the Committee shall constitute a quorum and any action may be taken by a majority of those present and voting at any

meeting. Any action may also be taken without the necessity of a meeting by a written instrument signed by a majority of the Committee. The decision of the Committee as to all questions of interpretation and application of the Plan shall be final, binding and conclusive on all persons. The Committee shall have the authority to adopt, amend and rescind such rules and regulations as, in its opinion, may be advisable in the administration of the Plan. The Committee may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any option or restricted stock agreement granted hereunder in the manner and to the extent it shall deem expedient to carry the Plan into effect and shall be the sole and final judge of such expediency. No Committee member shall be liable for any action or determination made in good faith.

TYPE OF OPTIONS.

Options granted pursuant to the Plan shall be authorized by action of the Committee and may be designated as either incentive stock options meeting the requirements of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or non-qualified options which are not intended to meet the requirements of such Section 422 of the Code, the designation to be in the sole discretion of the Committee. The Plan shall be administered by the Committee in such manner as to permit options to qualify as incentive stock options under the Code.

ELIGIBILITY.

Options designated as incentive stock options shall be granted only to employees (including officers and directors who are also employees) of the Company and any of its subsidiaries. Options designated as non-qualified options may be granted to officers, directors, employees, consultants, and advisors of the Company or of any of its subsidiaries. “Subsidiary” or “subsidiaries” shall be as defined in Section 424 of the Code and the Treasury Regulations promulgated thereunder (the “Regulations”) and shall include present and future subsidiaries.

The Committee shall, from time to time, at its sole discretion, select from such eligible individuals those to whom options shall be granted and shall determine the number of shares to be subject to each option. In determining the eligibility of an individual to be granted an option, as well as in determining the number of shares to be granted to any individual, the Committee in its sole discretion shall take into account the position and responsibilities of the individual being considered, the nature and value to the Company or its subsidiaries of his or her service and accomplishments, his or her present and potential contribution to the success of the Company or its subsidiaries, and such other factors as the Committee may deem relevant.

No option designated as an incentive stock option shall be granted to any employee of the Company or any subsidiary if such employee owns, immediately prior to the grant of an option, stock representing more than 10% of the combined voting power of all classes of stock of the Company or a parent or a subsidiary, unless the purchase price for the stock under such option shall be at least 110% of its fair market value at the time such option is granted and the option, by its terms, shall not be exercisable more than five years from the date it is granted. In determining the stock ownership under this paragraph, the provisions of Section 424(d) of the Code shall be controlling. In determining the fair market value under this paragraph, the provisions of Section 7 hereof shall apply.

The maximum number of shares of the Company’s Common Stock with respect to which an option or options may be granted to any employee in any one taxable year of the Company shall not exceed 200,000 shares, taking into account shares granted during such taxable year under options that are terminated or repriced.

OPTION AGREEMENT.

(a) Each option shall be evidenced by an option agreement (the “Agreement”) duly executed on behalf of the Company and by the optionee to whom such option is granted, which Agreement shall comply with and be subject to the terms and conditions of the Plan. The Agreement may contain such other terms, provisions and conditions which are not inconsistent with the Plan as may be determined by the Committee, provided that options designated as incentive stock options shall meet all of the conditions for incentive stock options as defined in Section 422 of the Code. The date of grant of an option shall be as determined by the Committee. More than one option may be granted to an individual.

(b) Unless the Agreement specifies otherwise, the Committee may cancel, rescind, suspend, withhold or otherwise limit or restrict any option (whether vested or unvested, exercised or unexercised) at any time if the optionee is not in compliance with all applicable provisions of the Agreement and the Plan, or if the optionee engages in any “Detrimental Activity.” For purposes of this Section 6, “Detrimental Activity” shall include: (i) the rendering of services for any organization or engaging directly or indirectly in any business which is or becomes competitive with the Company, or which organization or business, or the rendering of services to such organization or business, is or becomes otherwise prejudicial to or in conflict with the interests of the Company; (ii) the disclosure to anyone outside the Company, or the use in other than the Company’s business, without prior written authorization from the Company, of any confidential information or material, as defined in the Company’s Employee Confidentiality Agreement or such other agreement regarding confidential information and intellectual property that the optionee and the Company may enter into (collectively, the “Confidentiality Agreement”), relating to the business of the Company, acquired by the optionee either during or after employment with the Company; (iii) the failure or refusal to disclose promptly and to assign to the Company, pursuant to the Confidentiality Agreement or otherwise, all right, title and interest in any invention or idea, patentable or not, made or conceived by the optionee during employment by the Company, relating in any manner to the actual or anticipated business, research or development work of the Company or the failure or refusal to do anything reasonably necessary to enable the Company to secure a patent where appropriate in the United States and in other countries; (iv) activity that results in termination of the optionee’s employment for cause; (v) a material violation of any rules, policies, procedures or guidelines of the Company; (vi) any attempt directly or indirectly to induce any employee of the Company to be employed or perform services elsewhere or any attempt directly or indirectly to solicit the trade or business of any current or prospective customer, supplier or partner of the Company; or (vii) the optionee being convicted of, or entering a guilty plea with respect to, a crime, whether or not connected with the Company.

(c) Upon exercise, payment, or delivery pursuant to an option, the optionee shall certify in a manner acceptable to the Company that he or she is in compliance with the terms and conditions of the Plan. In the event an optionee engages in any Detrimental Activity

as set forth in paragraphs (b)(i)-(vii) of this Section 6 prior to, or during the six (6) months after, any exercise, payment, or delivery pursuant to an option, such exercise, payment, or delivery may be rescinded by the Company within two (2) years thereafter. In the event of any such rescission, the optionee shall pay to the Company the amount of any gain realized or payment received as a result of the rescinded exercise, payment, or delivery, in such manner and on such terms and conditions as may be required, and the Company shall also be entitled to set-off against the amount of any such gain any amount owed to the optionee by the Company, and to be reimbursed for any attorney’s fees or other costs or expenses incurred in enforcing this Section 6 of the Plan.

OPTION PRICE.

The option price or prices of shares of the Company’s Common Stock for options designated as non-qualified stock options shall be determined by the Committee, but in no event shall the option price of a non-qualified stock option be less than 100% of the fair market value of such Common Stock at the time the option is granted, as determined by the Committee. The option price or prices of shares of the Company’s Common Stock for incentive stock options shall be not less than the fair market value of such Common Stock at the time the option is granted as determined by the Committee in accordance with the Regulations promulgated under Section 422 of the Code. If the shares of Common Stock are listed on any national securities exchange, or traded on the National Association of Securities Dealers Automated Quotation System (“Nasdaq”) National Market System, the fair market value of a share of Common Stock on the date of grant of an option shall be the closing price, if any, on the largest such exchange, or if not traded on an exchange, the Nasdaq National Market System on such day, or if the date of grant is not a business day, the business day immediately preceding the date of the grant, or if there are no sales of shares of Common Stock on the date of grant or on the business day immediately preceding the date of grant, the fair market value of a share of Common Stock shall be determined by taking a weighted average of the means between the highest and lowest sales on the nearest date before and the nearest date after the date of grant in accordance with Treasury Regulations Section 25.2512-2. If the shares are not then either listed on any such exchange or quoted in NASDAQ/NM, the fair market value shall be the mean between the average of the “Bid” and the average of the “Ask” prices, if any, as reported in the National Daily Quotation Service for the date of grant, or if the date of grant is not a business day the business day immediately preceding the date of the grant of the option, or, if none, shall be determined by taking a weighted average of the means between the highest and lowest sales prices on the nearest date before and the nearest date after the date of grant in accordance with Treasury Regulations Section 25.2512-2. If the fair market value cannot be determined under the preceding two sentences, it shall be determined in good faith by the Committee.

MANNER OF PAYMENT; MANNER OF EXERCISE.

(a) Options granted under the Plan may provide for the payment of the exercise price, as determined by the Committee and set forth in the Agreement, by delivery of (i) cash or a check payable to the order of the Company in an amount equal to the exercise price of such options, (ii) shares of Common Stock of the Company owned by the optionee having a fair market value equal in amount to the exercise price of the options being exercised, (iii) any combination of (i) and (ii), provided, however, that payment of the exercise price by delivery of

shares of Common Stock of the Company owned by such optionee may be made only if such payment does not result in a charge to earnings for financial accounting purposes as determined by the Committee, or (iv) payment may also be made by delivery of a properly executed exercise notice to the Company, together with a copy of irrevocable instruments to a broker to deliver promptly to the Company the amount of sale or loan proceeds to pay the exercise price. The fair market value of any shares of the Company’s Common Stock which may be delivered upon exercise of an option shall be determined by the Committee in accordance with Section 7 hereof. To facilitate clause (iv) above, the Company may enter into agreements for coordinated procedures with one or more brokerage firms. The date of exercise shall be the date of delivery of such exercise notice.

(b) To the extent that the right to purchase shares under an option has accrued and is in effect, options may be exercised in full at one time or in part from time to time, by giving written notice, signed by the person or persons exercising the option, to the Company, stating the number of shares with respect to which the option is being exercised, accompanied by payment in full for such shares as provided in subparagraph (a) above. Upon such exercise, delivery of a certificate for paid-up non-assessable shares shall be made at the principal office of the Company to the person or persons exercising the option at such time, during ordinary business hours, after 9:00 a.m. but not more than thirty (30) days from the date of receipt of the notice by the Company, as shall be designated in such notice, or at such time, place and manner as may be agreed upon by the Company and the person or persons exercising the option. Upon exercise of the option and payment as provided above, the optionee shall become a stockholder of the Company as to the Shares acquired upon such exercise.

VESTING OF OPTIONS.

Except as otherwise provided in an optionee’s Agreement, each option granted under the Plan shall, subject to Section 10 and Section 12 hereof, be exercisable with reference to the option’s Vesting Reference Date (the date selected by the Committee) as follows: prior to the First Anniversary Date of the Vesting Reference Date—zero percent (0%); on the First Anniversary Date of the Vesting Reference Date—twenty five percent (25%); on the Second Anniversary Date of the Vesting Reference Date—fifty percent (50%); on the Third Anniversary Date of the Vesting Reference Date—seventy-five percent (75%); and on the Fourth Anniversary Date of the Vesting Reference Date—one hundred percent (100%). Notwithstanding any other provisions of this section, in the event of a Change of Control (as hereinafter defined) of the Company, fifty percent (50%) of the unvested shares of each Participant with a minimum of six months’ service will automatically be fully Vested; in the event of a Change of Control of the Company not approved by the Board of Directors prior to such Change of Control, all of the Shares shall be fully Vested immediately upon such Change of Control. For purposes of the Plan, a “Change of Control” shall be deemed to have occurred if any of the following conditions have occurred: (1) the merger or consolidation of the Company with another entity where the Company is not the surviving entity and where after the merger or consolidation (i) its stockholders prior to the merger or consolidation hold less than 50% of the voting stock of the surviving entity and (ii) its Directors prior to the merger or consolidation are less than a majority of the Board of the surviving entity; (2) the sale of all or substantially all of the Company’s assets to a third party and subsequent to the transaction (i) its stockholders hold less than 50% of the stock of said third party and (ii) its Directors are less than a majority of the Board of said

third party; (3) a transaction or series of related transactions, including a merger of the Company with another entity where the Company is the surviving entity, whereby 50% or more of the voting stock of the Company is transferred to parties who are not prior thereto stockholders or affiliates of the Company; or (4) the Continuing Directors shall not constitute a majority of the Board of Directors of the Company. The term “Continuing Directors” shall mean a member of the Board of Directors of the Company who either was a member of the Board of Directors of the Company on the date this Plan was adopted by the Board of Directors or who subsequently became a director of the Company and whose initial appointment, initial election or initial nomination for election by the Company’s shareholders subsequent to such date was approved by a vote of a majority of the Continuing Directors then on the Board of Directors of the Company.

To the extent that an option to purchase shares is not exercised by an optionee when it becomes initially exercisable, it shall not expire but shall be carried forward and shall be exercisable, on a cumulative basis, until the expiration of the exercise period. No partial exercise may be made for less than fifty (50) full shares of Common Stock.

Notwithstanding the foregoing, the Committee may in its discretion (i) specifically provide for another time or times of exercise (but not delay a vesting period) or (ii) accelerate the exercisability of any option subject to such terms and conditions as the Committee deems necessary and appropriate.

10.

TERM AND EXERCISABILITY OF OPTIONS; RELATIONSHIP TO VESTING; NON-EMPLOYEE OPTIONS.

(a) TERM AND EXERCISABILITY.

(1) The term of each option shall be as stated in the optionee’s Agreement, provided, however, that the term of an option shall not exceed ten (10) years from the date of the granting thereof, subject to earlier termination as provided in the Plan and the Agreement.

(2) Except as otherwise provided in the optionee’s Agreement, or this Section 10, an option granted to any employee who ceases to be an employee of the Company or one of its subsidiaries shall terminate ninety (90) days after the date of such optionee ceases to be an employee of the Company or one of its subsidiaries, or on the last day of the term of the option, whichever occurs first.

(3) Except as otherwise provided in the optionee’s Agreement, if such termination of employment is because of dismissal for cause or because the employee is in breach of any employment agreement, such option will terminate on the date the optionee ceases to be an employee of the Company or one of its subsidiaries, or on the last day of the term of the option, whichever occurs first.

(4) Except as otherwise provided in the optionee’s Agreement, if such termination of the employment is because the optionee has become permanently disabled (within the meaning of Section 22(e)(3) of the Code), such option shall terminate on the

last day of the twelfth month from the date such optionee ceases to be an employee, or on the last day of the term of the option, whichever occurs first.

(5) Except as otherwise provided in the optionee’s Agreement, in the event of the death of an optionee, any option granted to such optionee shall terminate on the last day of the twelfth month from the date of death, or on the last day of the term of the option, whichever occurs first.

(6) Except as otherwise provided in the optionee’s Agreement, if such termination of employment is because of the retirement of the optionee on or after attaining the minimum age, completing the minimum number of years of service, and satisfying of all other conditions specified for retirement status under the Company’s Retirement Policy Statement as in effect at the time of the grant of the option, such option will terminate on the date that is five (5) years after the date the optionee ceases to be an employee of the Company or one of its subsidiaries, or the last day of the term of the option, whichever occurs first.

(7) Notwithstanding subparagraphs (2) through (6) above, the Committee shall have the authority to extend the expiration date of any outstanding option in circumstances in which it deems such action to be appropriate.

(b) RELATIONSHIP TO VESTING. Except as otherwise provided in the optionee’s agreement, an option granted to an employee who ceases to be an employee of the Company or one of its subsidiaries, whether by having become permanently disabled, as defined in Sedition 22(e)(3) of the Code, by death, or otherwise, shall be exercisable only to the extent that the right to purchase shares under such option has vested and accrued on the date that such optionee ceases to be an employee of the Company or one of its subsidiaries.

(c) NON-EMPLOYEE OPTIONS. The term of an option granted to a non-employee director, a consultant, or any other person who is not an employee of the Company or one of its subsidiaries shall be stated in the optionee’s Agreement, provided, however, that the term of an option shall not exceed ten (10) years from the date of the granting thereof, subject to earlier termination as provided in the Plan and the Agreement. An option granted to a non-employee director, a consultant, or any other person who is not an employee of the Company or one of its subsidiaries shall be exercisable only to the extent so provided in the optionee’s Agreement.

11.

OPTIONS NOT TRANSFERABLE.

The right of any optionee to exercise any option granted to him or her shall not be assignable or transferable by such optionee otherwise than by will or the laws of descent and distribution, and any such option shall be exercisable during the lifetime of such optionee only by him; provided, however, that in the case of a non-qualified stock option, the Committee may permit transferability of such options on such terms and conditions as determined by the Committee and set forth in the Option Agreement. Any option granted under the Plan shall be null and void and without effect upon the bankruptcy of the optionee to whom the option is granted, or upon any attempted assignment or transfer, except as herein provided, including

without limitation any purported assignment, whether voluntary or by operation of law, pledge, hypothecation or other disposition, attachment, divorce, trustee process or similar process, whether legal or equitable, upon such option.

11A.

RESTRICTED STOCK AWARDS.

(a) A restricted stock award entitles the recipient to acquire, at such purchase price as determined by the Committee, shares of Common Stock subject to such restrictions and conditions as the Committee may determine at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The grant of a restricted stock award is contingent on the grantee executing the restricted stock award agreement. The terms and conditions of each such agreement shall be determined by the Committee, and such terms and conditions may differ among individual restricted stock awards and grantees.

(b) Upon execution of a written instrument setting forth the restricted stock award and payment of any applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the restricted stock, subject to such conditions contained in the written instrument evidencing the restricted stock award. Unless the Committee shall otherwise determine, certificates evidencing the restricted stock shall remain in the possession of the Company until such restricted stock is vested as provided in Section 11A(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank.

(c) Restricted stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the restricted stock award agreement. If a grantee’s employment (or other service relationship) with the Company and its subsidiaries terminates for any reason, the Company shall have the right to repurchase restricted stock that has not vested at the time of termination at its original purchase price, from the grantee or the grantee’s legal representative.

(d) The Committee at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the restricted stock and the Company’s right of repurchase or forfeiture shall lapse. Subject to the power of the Committee to accelerate vesting upon a Change of Control, the vesting period for restricted stock shall be at least three years, except that in the case of restricted stock that becomes transferable and no longer subject to risk of forfeiture upon the attainment of pre-established goals, objectives and other conditions, the vesting period shall be at least one year. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be restricted stock and shall be deemed “vested.” Except as may otherwise be provided by the Committee either in the restricted stock award agreement or, subject to Section 19 below, in writing after the restricted stock award agreement is issued, a grantee’s rights in any shares of restricted stock that have not vested shall automatically terminate upon the grantee’s termination of employment (or other service relationship) with the Company and its subsidiaries and such shares shall be subject to the Company’s right of repurchase as provided in Section 11A(c) above.

(e) The restricted stock award agreement may require or permit the immediate payment, waiver, deferral or investment of dividends paid on the restricted stock.

12.

RECAPITALIZATIONS, REORGANIZATIONS AND THE LIKE.

(a) In the event that the outstanding shares of the Common Stock of the Company are changed into or exchanged for a different number or kind of shares or other securities of the Company or of another corporation by reason of any reorganization, merger, consolidation, recapitalization, reclassification, stock split-up, combination of shares, or dividends payable in capital stock, appropriate adjustment shall be made in the number and kind of shares as to which options or restricted stock awards may be granted under the Plan and as to which outstanding options or portions thereof then unexercised shall be exercisable and as to the repurchase price per share subject to each outstanding restricted stock award, to the end that the proportionate interest of the optionee or restricted stock holder shall be maintained as before the occurrence of such event; such adjustment in outstanding options shall be made without change in the total price applicable to the unexercised portion of such options and with a corresponding adjustment in the option price per share.

(b) In addition, unless otherwise determined by the Committee in its sole discretion, in the case of any Change of Control of the Company, the purchaser(s) of the Company’s assets or stock may, in his, her or its discretion, deliver to the optionee the same kind of consideration that is delivered to the stockholders of the Company as a result of such sale, conveyance or Change of Control, or the Committee may cancel all outstanding options in exchange for consideration in cash or in kind, which consideration in both cases shall be equal in value to the value of those shares of stock or other securities the optionee would have received had the option been exercised (to the extent then exercisable) and no disposition of the shares acquired upon such exercise been made prior to such Change of Control, less the option price therefor. Upon receipt of consideration by the optionee, his or her option shall immediately terminate and be of no further force and effect. The value of the stock or other securities the optionee would have received if the option had been exercised shall be determined in good faith by the Committee, and in the case of shares of the Common Stock of the Company, in accordance with the provisions of Section 7 hereof. The Committee shall also have the power and right to accelerate the exercisability of any options, or to accelerate the vesting of any restricted stock awards, notwithstanding any limitations in this Plan or in the Agreement upon such Change of Control. Upon such acceleration, any options or portion thereof originally designated as incentive stock options that no longer qualify as incentive stock options under Section 422 of the Code as a result of such acceleration shall be redesignated as non-qualified stock options.

(c) Upon dissolution or liquidation of the Company, all options and restricted stock awards granted under this Plan shall terminate, but each optionee (if at such time in the employ of or otherwise associated with the Company or any of its subsidiaries) shall have the right, immediately prior to such dissolution or liquidation, to exercise his or her option to the extent then exercisable.

(d) No fraction of a share shall be purchasable or deliverable upon the exercise of any option or the vesting of any restricted stock award, but in the event any

adjustment hereunder of the number of shares covered by the option or restricted stock award shall cause such number to include a fraction of a share, such fraction shall be adjusted to the nearest smaller whole number of shares.

13.

NO SPECIAL EMPLOYMENT RIGHTS.

Nothing contained in the Plan or in any option or restricted stock award granted under the Plan shall confer upon any optionee or restricted stock holder any right with respect to the continuation of his or her employment by the Company (or any subsidiary thereof) or interfere in any way with the right of the Company (or any subsidiary thereof), subject to the terms of any separate employment agreement to the contrary, at any time to terminate such employment or to increase or decrease the compensation of the optionee or restricted stock holder from the rate in existence at the time of the grant of an option or restricted stock award. Whether an authorized leave of absence, or absence in military or government service, shall constitute termination of employment shall be determined by the Committee at the time.

14.

WITHHOLDING.

The Company’s obligation to deliver shares upon the exercise of any option or vesting of any restricted stock award granted under the Plan and any payments or transfers under Section 12 hereof shall be subject to the optionee or restricted stock holder’s satisfaction of all applicable Federal, state and local income, excise, employment and any other tax withholding requirements.

15.

RESTRICTIONS ON ISSUE OF SHARES.

(a) Notwithstanding the provisions of Section 8, the Company may delay the issuance of shares covered by the exercise of an option or restricted stock award and the delivery of a certificate for such shares until one of the following conditions shall be satisfied:

(1) The shares with respect to the restricted stock award or with respect to which such option has been exercised are at the time of the issue of such shares effectively registered or qualified under applicable Federal and state securities acts now in force or as hereafter amended; or

(2) Counsel for the Company shall have given an opinion, which opinion shall not be unreasonably conditioned or withheld, that such shares are exempt from registration and qualification under applicable Federal and state securities acts now in force or as hereafter amended.

(b) It is intended that all exercises of options or grant of restricted stock awards shall be effective, and the Company shall use its best efforts to bring about compliance with the above conditions within a reasonable time, except that the Company shall be under no obligation to qualify shares or to cause a registration statement or a post-effective amendment to any registration statement to be prepared for the purpose of covering the issue of shares in respect of which any option may be exercised or with respect to any restricted stock award, except as otherwise agreed to by the Company in writing.

16.

PURCHASE FOR INVESTMENT; RIGHTS OF HOLDER ON SUBSEQUENT REGISTRATION.

Unless the shares to be issued upon the vesting of a restricted stock award or exercise of an option granted under the Plan have been effectively registered under the Securities Act of 1933, as now in force or hereafter amended, the Company shall be under no obligation to issue any shares covered by any restricted stock award or option unless the person who receives such restricted stock award or exercises such option, in whole or in part, shall give a written representation and undertaking to the Company which is satisfactory in form and scope to counsel for the Company and upon which, in the opinion of such counsel, the Company may reasonably rely, that he or she is acquiring the shares issued pursuant to such restricted stock award or to such exercise of the option for his or her own account as an investment and not with a view to, or for sale in connection with, the distribution of any such shares, and that he or she will make no transfer of the same except in compliance with any rules and regulations in force at the time of such transfer under the Securities Act of 1933, or any other applicable law, and that if shares are issued without such registration, a legend to this effect may be endorsed upon the securities so issued. In the event that the Company shall, nevertheless, deem it necessary or desirable to register under the Securities Act of 1933 or other applicable statutes any shares with respect to a restricted stock award or to which an option shall have been exercised, or to qualify any such shares for exemption from the Securities Act of 1933 or other applicable statutes, then the Company may take such action and may require from each optionee or restricted stock holder such information in writing for use in any registration statement, supplementary registration statement, prospectus, preliminary prospectus or offering circular as is reasonably necessary for such purpose and may require reasonable indemnity to the Company and its officers and directors and controlling persons from such optionee or holder against all losses, claims, damages and liabilities arising from such use of the information so furnished and caused by any untrue statement of any material fact therein or caused by the omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made.

17.

MODIFICATION OF OUTSTANDING OPTIONS.

The Committee may authorize the amendment of any outstanding option or restricted stock award with the consent of the optionee or restricted stock holder when and subject to such conditions as are deemed to be in the best interests of the Company and in accordance with the purposes of this Plan.

18.

APPROVAL OF STOCKHOLDERS.

The Plan shall be subject to approval by the vote of stockholders holding at least a majority of the voting stock of the Company present, or represented, and entitled to vote at a duly held stockholders’ meeting, or by written consent of the stockholders as provided for under applicable state law, within twelve (12) months after the adoption of the Plan by the Board of Directors and shall take effect as of the date of adoption by the Board of Directors upon such approval. The Committee may grant options under the Plan prior to such approval, but any such option shall become effective as of the date of grant only upon such approval and, accordingly, no such option may be exercisable prior to such approval.

19.

TERMINATION AND AMENDMENT.

Unless sooner terminated as herein provided, the Plan shall terminate ten (10) years from the date upon which the Plan was duly adopted by the Board of Directors of the Company. The Board of Directors may at any time terminate the Plan or make such modification or amendment thereof as it deems advisable; provided, however, that except as provided in this Section 19, the Board of Directors may not, without the approval of the stockholders of the Company obtained in the manner stated in Section 18, increase the maximum number of shares for which options or restricted stock awards may be granted or change the designation of the class of persons eligible to receive options or restricted stock awards under the Plan, or make any other change in the Plan which requires stockholder approval under applicable law or regulations.

20.

RESERVATION OF STOCK.

The Company shall at all times during the term of the Plan reserve and keep available such number of shares of stock as will be sufficient to satisfy the requirements of the Plan and shall pay all fees and expenses necessarily incurred by the Company in connection therewith.

21.

LIMITATION OF RIGHTS IN THE OPTION SHARES.

An optionee shall not be deemed for any purpose to be a stockholder of the Company with respect to any of the options except to the extent that the option shall have been exercised with respect thereto and, in addition, a certificate shall have been issued theretofore and delivered to the optionee.

22.

NOTICES.

Any communication or notice required or permitted to be given under the Plan shall be in writing, and mailed by registered or certified mail or delivered by hand, if to the Company, to its principal place of business, attention: President, and, if to an optionee or restricted stock holder, to the address as appearing on the records of the Company.
