        We will be required to use the net proceeds of this offering for working capital purposes and not for the satisfaction of debt or outstanding liabilities, subject to specific exceptions.


PLAN OF DISTRIBUTION

        To date, before the issuance of the securities being offered pursuant to this prospectus supplement, we have issued and sold secured convertible debentures due August 12, 2007 in the aggregate principal amount of $10,000,000 and 23,722,958 shares of our common stock (which includes 3,699,543 shares of common stock issued upon conversion of $1,800,000 aggregate principal amount of such secured convertible debentures) pursuant to the prospectus dated January 3, 2002, which is part of our Registration Statement on Form S-3 (File No. 333-76092) for aggregate proceeds of $32,156,640.60. We have also issued warrants originally to purchase an additional 5,500,000 shares of our common stock under such Registration Statement, although warrants to purchase 3,000,000 of such shares expired without being exercised by the holders thereof.

        We are offering 2% convertible debentures due 2006 (the "Debentures") in the aggregate principal amount of $11,000,000 and 5,650,000 shares of common stock (the "Shares") under this prospectus supplement for aggregate consideration of approximately $11,000,000. The Debentures and Shares being offered hereunder are referred to collectively herein as the "Securities".

        We have negotiated a term sheet with a group of investors (the "Purchasers") pursuant to which we expect to issue and sell to the Purchasers the Securities. We are in negotiations with the Purchasers regarding the sale of the Securities being offered hereunder, and expect that we will enter into a definitive securities purchase agreement with the Purchasers which will set forth the specific terms of the transaction (the "Purchase Agreement"). Until the Purchase Agreement has been executed, the Purchasers will not be obligated to purchase the securities offered hereby.

        We expect that the Debentures will be convertible into shares of our common stock at an initial conversion price equal to the lesser of (i) 110% of the average volume weighted average trading price per share of common stock for the ten trading days preceding the closing date of the sale of the Securities and (ii) $1.00, subject to adjustment on the terms and conditions set forth in the Debentures. We will allocate a portion of the proceeds from the sale of the Securities to 5,000,000 of the Shares based on a price equal to the trading price of our common stock on the closing date under the Purchase Agreement.

        In addition, upon a purchase by the Purchasers of the Securities, we will issue to the lead purchaser ("Lead Purchaser") 650,000 shares of common stock, comprising the balance of the Shares, and will pay the Lead Purchaser $20,000 in cash for reimbursement of expenses incurred in connection with the negotiation of the transactions contemplated by the Purchase Agreement. To date, we have already reimbursed the Lead Purchaser an aggregate of $30,000 for the legal fees and expenses incurred in connection with the preparation and negotiation of the Purchase Agreement.

        Pursuant to an engagement letter dated September 17, 2002, as amended on November 1, 2002, we have engaged Roth Capital to act as our exclusive placement agent in connection with offerings of securities under our shelf Registration Statement on Form S-3 (File No. 333-76092). The initial term of our engagement of Roth Capital expired December 17, 2002. Under the terms of the engagement letter, Roth Capital agreed to assist us in raising capital on a "best efforts" basis, and was not obligated purchase or acquire any of our securities. With respect to offerings consummated during the term of

S-1



the engagement, we have agreed to pay Roth Capital a placement fee of 7.5% of the gross proceeds received from the sale of securitiesand issue warrants to purchase an amount equal to 10% of the securities issued in the offering with a 5-year term and a strike price equal to 120% of the closing price of the date of the offering. Under certain circumstances, including consummation of the transactions contemplated by the Purchase Agreement, the engagement letter would require us to pay a placement fee to Roth Capital in connection with an offering consummated during a period of up to six months following the termination of the engagement. In addition, we have agreed to reimburse Roth Capital for up to $25,000 of its out-of- pocket expenses, including the fees and expenses of Roth Capital's legal counsel, incurred in connection with the engagement. We have also agreed to indemnify Roth Capital against certain liabilities arising in connection with the engagement, including liabilities under federal securities laws. We will not pay any other compensation in connection with the sale of the Securities pursuant to the Purchase Agreement.

        Under the Purchase Agreement, we will agree to indemnify and hold harmless each of the Purchasers and their affiliates or any officers, directors, partners, controlling persons, employees or agents of any such Purchaser against certain liabilities arising under the Securities Act of 1933 and otherwise as more fully set forth in the Purchase Agreement.


MARKET FOR OUR COMMON STOCK

        Our common stock is listed on the NASDAQ National Market under the symbol "ERTH". On February 13, 2003, the closing price per share of our common stock was $0.53. The common stock offered under this prospectus supplement, including the shares of common stock issuable in connection with the Debentures, will be listed on the trading market on which our common stock is then listed after we notify such market that the shares have been issued. As of February 13, 2003, we had 146,424,666 shares of common stock outstanding.


CERTAIN PROVISIONS RELATED TO OFFER OF SECURITIES

        We expect that the following provisions will apply in connection with the offer and sale of the Securities.

Right of First Offer

        If we propose a subsequent offer of equity securities or securities convertible into equity securities, we will generally be required to offer the holders of the Debentures the right to purchase such securities before offering such securities to any third parties.

Lock-Up of 5,000,000 Shares of Common Stock

        Each Purchaser of the 5,000,000 shares which may be purchased under the Purchase Agreement and which constitute that portion of the Shares being offered hereby will be required to agree not to sell, assign or otherwise transfer more than one-sixth of the Shares purchased by such Purchaser during any month, provided that such Purchaser may carry forward and sell during any subsequent month any Shares that could have been sold but were not sold during any prior month.

Amendment and Waiver of Existing Secured Convertible Debentures

        In connection with a closing of the purchase and sale of the Securities offered hereby, we may amend the terms of the Previous Debentures (as defined below). Such amendments may include, among others, prepayment of portions of the Previous Debentures and amendment of existing terms that may be affected by the offering of the Debentures, such as the anti-dilution provisions of the Previous Debentures.
