(the "Issuer"). The principal executive offices of the Issuer are located at 1675 West Maple Road, Troy, Michigan 48084. ITEM 2. Identity and Background. This statement is being filed by Texaco Inc. ("Texaco"), a Delaware corporation. The principal executive offices of Texaco are located at 2000 Westchester Avenue, White Plains, New York 10650. Texaco and its subsidiary companies, together with affiliates owned 50% or less, represent a vertically integrated enterprise principally engaged in the worldwide exploration for and production, transportation, refining and marketing of crude oil, natural gas liquids, natural gas and petroleum products, power generation and gasification. The name, business address and present principal occupation or employment of each director and executive officer of Texaco is set forth in Appendix A attached hereto. All of such persons are citizens of the United States, except as otherwise indicated in Appendix A. During the last five years, neither Texaco nor any of the individuals listed in Appendix A has been convicted in any criminal proceeding. During the last five years, neither Texaco nor any of the individuals listed in Appendix A has been party to any civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which it or such person was or is subject to any judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or state securities laws or finding any violation with respect to such laws. ITEM 3. Source and Amount of Funds or Other Consideration. Texaco acquired all of its 3,742,800 shares of the Issuer's Common Stock (the "Shares") on May 31, 2000 pursuant to a Stock Purchase Agreement dated as of May 1, 2000 (the "Purchase Agreement") by and between the Issuer and TRMI Holdings Inc., a Delaware corporation and a wholly-owned subsidiary of Texaco. Funds used to purchase such shares totaled $67,370,400 and were derived from Texaco's working capital. ITEM 4. Purpose of the Transaction. Texaco acquired the Shares pursuant to the Purchase Agreement for investment purposes.

CUSIP NO. 292659109 Schedule 13D Page 4 of 13 Under the Purchase Agreement, and as more fully set forth therein, for so long as Texaco and its affiliates beneficially own an aggregate of more than five percent of the outstanding Common Stock: (1) The Issuer will not pursue a merger, consolidation or sale of all or substantially all of its assets (a "Business Combination") (other than pursuant to an unsolicited proposal) until 45 business days after it has given written prior notice to Texaco of its intention to pursue such transaction. During this time period, the Issuer shall negotiate in good faith with Texaco with a view toward entering into a definitive agreement setting forth the terms of a Business Combination with Texaco. If the parties are unable to enter into an agreement within the aforementioned period, the Issuer shall be free to initiate Business Combination discussions with other parties; (2) In the case of proposals that are either unsolicited or initiated by the Issuer, the Issuer is prohibited from entering into a binding agreement with any person relating to a Business Combination unless it notifies Texaco in writing at least 10 business days prior to entering into such an agreement. If Texaco notifies the Issuer of its intention to enter a Business Combination with the Issuer on comparable terms and conditions, the parties will act promptly and in good faith to negotiate a definitive agreement reflecting such terms and conditions. If Texaco and the Issuer are unable to negotiate and execute a definitive agreement, the Issuer may discontinue negotiations and enter into a Business Combination with another person upon terms and conditions not materially less favorable, in the aggregate to the Issuer and its stockholders, than the terms and conditions that would have been set forth in a definitive agreement covering a Business Combination with Texaco; (3) Neither Texaco nor its affiliates will, directly or indirectly, acquire an equity interest exceeding 20 percent of the Issuer's Common Stock without the Issuer's prior consent; (4) Neither Texaco nor its affiliates shall, without the Issuer's prior consent, (i) propose to enter into any merger, consolidation, recapitalization, business combination or other similar transaction involving the Issuer or any of its affiliates, (ii) make or participate in any solicitation of proxies with respect to the voting of any voting securities of the Issuer, (iii) form, join or in any way participate in a group with respect to any of the Issuer's voting securities, (iv) disclose any intention, plan or arrangement inconsistent with the foregoing, or (v) advise, assist or encourage other persons (including specifically the Issuer's stockholders) in connection with the foregoing. Texaco has further agreed not to take any action which may require the Issuer to make a public announcement concerning the possibility of a merger, consolidation, business combination or other similar transaction;

CUSIP NO. 292659109 Schedule 13D Page 5 of 13 (5) Texaco will be entitled to hold two seats on the Issuer's Board of Directors (or one-fifth of the number of directors then serving, if greater) to the extent that its holdings of Common Stock exceed 10 percent of the class outstanding. If Texaco's holdings exceed 5 percent but total less than 10 percent of the outstanding Common Stock, the number of seats on the Issuer's Board of Directors to which it is entitled to hold will be reduced to one. Texaco will also be entitled to have one of its designees serve on appropriate committees of the Issuer's Board of Directors, including the audit committee and any committee established for the purpose of succession planning. The Issuer has also agreed to create a Vice President of Marketing position prior to November 1, 2000 for the purpose of commercializing the Issuer's technology; (6) The Issuer will not adopt any amendments to its certificate of incorporation or by-laws or recommend to its stockholders any action which would (i) impose limits on Texaco's legal rights including, without limitation, the issuance (other than pursuant to options outstanding as of the date of the Purchase Agreement) or proposed issuance of any other class of securities having voting power disproportionately greater than the Common Stock; (ii) deny any benefit to Texaco as a holder of Common Stock that is made available to other holders of Common Stock generally; or (iii) alter the voting or other rights of the holders of Common Stock so that such rights (or the vote required with respect to any matter) are determined in reference to the amount of Common Stock held by Texaco. In addition, the Purchase Agreement contemplates that the Issuer and Texaco will enter into joint ventures for the continued development and commercialization of advanced energy technologies, initially in the fields of the Issuer's Ovonic solid hydrogen storage technology and the Ovonic regenerative fuel cell. ITEM 5. Interest in Securities of the Issuer. (a) Number of Shares Beneficially Owned: 3,742,800 shares of Common Stock.

(b) Sole Power to Vote, Direct the Vote of, or Dispose of Shares: 3,742,800.

CUSIP NO. 292659109 Schedule 13D Page 6 of 13 (c) Recent Transactions: On May 8, 2000, Elizabeth P. Smith, Vice President of Texaco, purchased 2,000 shares of Common Stock of the Issuer at a per share price of $22.0625, for a total purchase price of $44,125. The purchase was effected through a brokerage account controlled jointly by Mrs. Smith and her spouse. Except for such purchase and except as described in Item 3, neither Texaco nor any of the persons listed in Appendix A hereto effected any transactions in the Common Stock of the Issuer in the past 60 days. (d) Rights with Respect to Dividends or Sales Proceeds: Not Applicable (e) Date of Cessation of Five Percent Beneficial Ownership: Not Applicable ITEM 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. Pursuant to the Purchase Agreement, Texaco has the right at any time one year after its purchase of the Common Stock to request that the Issuer prepare and file with the Securities and Exchange Commission (the "Commission") a single registration statement covering all of the Shares or at least 250,000 shares of Common Stock. In addition, Texaco has certain "piggyback" registration rights in the event that the Issuer files a registration statement with the Commission in respect of an offering by the Issuer for its own account or for the account of any of the holders of the Issuer's securities, other than a registration statement on Form S-4 or Form S-8 (or any substitute or successor form that is adopted by the Commission). So long as Texaco and its affiliates beneficially own an aggregate of more than five percent of the Issuer's Common Stock, Texaco has certain preemptive rights to acquire additional shares of Common Stock to maintain its proportionate stock ownership interest in the Issuer in the event that the Issuer sells or otherwise issues additional shares of its Common Stock. Texaco has also agreed under certain circumstances to vote the Shares in accordance with votes cast by the holders of the Issuer's Class A Common Stock (prior to the conversion of the Class A Common Stock into Common Stock) or Class B Common Stock (after the conversion of the Class A Common Stock into Common Stock). Texaco may not sell, hypothecate or otherwise transfer any of the Shares for at least one year. In the event of a Change of Control (as defined in the Purchase Agreement) or if, after one year, Texaco wishes to sell any of the Shares, the Issuer shall have a right of first refusal to purchase such shares from Texaco.

On any sale of the Stock by Buyer to a single purchaser or a "group" (within the meaning of Section 13(d)(3) of the Securities Act) which represents more than Five Percent (5%) in the Seller Stock then outstanding, Buyer agrees to make the sale of the Stock by it subject to the agreement of the purchaser to be bound by the restrictions set forth in Section 4.2 (a) and (b). (ii) If there is a Change of Control or if, after the first anniversary of the Closing Date, Buyer desires to sell any the Stock, then Seller shall have a right to purchase the Stock. If Buyer intends to sell the Stock then it shall deliver a written notice to the Seller setting forth the proposed sale price and other proposed terms of sale, including the identity of any proposed transferee. If Seller intends to purchase the Stock, Seller shall notify Buyer in writing within Forty Five (45) Business Days of receipt of the Buyer's notice of intent to sell or a notice of Change of Control. In the case of a Change of Control, the price will be calculated on the same basis as the Purchase Price. In the case of an intent to sell, the acceptance will be on the specified terms and conditions specified in the notice. In either case, if Buyer does not receive Seller's acceptance within Forty Five (45) Business Days of Buyer's notice, Seller will have waived its right to purchase pursuant to this Section 4.3(f)(ii). 19

(iii) Notwithstanding Section 4.3(f)(ii), prior to the completion of a sale of the Stock to a Person, Buyer shall grant Seller a right of first refusal with respect to the specific terms offered by a Person. Buyer shall notify Seller in writing of the terms and conditions upon which the Person is willing to purchase the Stock. Seller shall have the right to purchase the Stock on the terms and conditions set forth in such notice. If Buyer does not receive Seller's acceptance within ten (10) Business Days of Buyer's notice Seller shall have waived its right to purchase and Buyer may sell the Stock on terms and conditions no less favorable to the proposed purchaser than specified in its notice. (g) Certain Filings and Consents. With respect to certain filings and consents, the Parties agree that: (i) Buyer and Seller shall promptly make all required submissions under the Hart Scott Rodino Antitrust Improvements Act of 1976 as amended ("HSR Act"); (ii) Buyer and Seller shall cooperate with one another in (x) determining whether any filings are required to be made or consents, approvals, permits or authorizations are required to be obtained under any Laws of the United States or any other country in which Seller has business activities, and (y) making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such consents, permits, authorizations, approvals or waivers; and (iii) Buyer shall promptly endeavor to obtain, and Seller shall reasonably cooperate in connection with such endeavors, each consent set forth on Schedules 3.1(e), 3.2(e) and 4.3(g), and (iv) Seller shall promptly endeavor to obtain, and Buyer shall reasonably cooperate in connection with such endeavors, each consent set forth on Schedules 3.1(e), 3.2(e) and 4.3(g). PART FIVE REGISTRATION RIGHTS Section 5.1 Registration. Upon the terms and subject to the conditions set forth in this Part Five, any time after the first anniversary of the Closing, Buyer may request a single registration (a "Stock Registration") under the Securities Act, of all or at least 250,000 shares of the Stock. Section 5.2 Expenses. The expenses of the holders of the Stock (other than underwriting discounts and commission applicable to the Stock of the Buyer to be sold) shall be paid by the Seller in connection with the Registration. Section 5.3 Other Seller Stock. The Seller shall not include in the Stock Registration any securities which are not Stock, without the prior written consent of the Buyer. If the Stock Registration is an underwritten offering and the managing underwriters advise Seller that in their opinion the number of shares of the Stock and, if permitted hereunder, other Seller Stock requested to be included in such offering, exceeds the number of shares of the Stock and other Stock which 20

can be sold in an orderly manner in such offering within a price range acceptable to the Buyer, the Seller shall include in such registration prior to the inclusion of any Seller Stock, which is not Stock, the Stock requested to be included, which in the opinion of such underwriters can be sold in an orderly manner within the price range of such offering. Section 5.4 Postponement. The Seller may postpone for up to One Hundred Eighty (180 days) the filing or the effectiveness of a registration statement for the Stock Registration if the Seller determines in good faith that such Stock Registration would reasonably be expected to have an adverse effect on any proposal or plan by the Seller to engage in any acquisition of assets (other than in the ordinary course of business), merger, consolidation or tender offer or to enter into any material license agreement, joint venture arrangement or similar transaction; provided that in such event, the holders of the Stock shall be entitled to withdraw such request and if such request is withdrawn, such Stock Registration shall not count as the permitted Stock Registration hereunder and the Seller shall pay all expenses in connection with such registration. Section 5.5 Piggyback Registration. Whenever the Seller proposes to register any of its securities under the Securities Act (other than pursuant to a Stock Registration and other than registrations on Form S-4, Form S-8 or any similar or successor registration forms) and the registration form to be used may be used for the registration of the Seller Stock (a "Piggyback Registration"), the Seller shall give prompt written notice to the Buyer of its intention to effect such a registration and shall include in such registration all Seller Stock with respect to which the Seller has received written requests for inclusion therein within 15 days after the giving of the Seller's notice. The expenses of the holders of the Seller Stock (other than underwriting discounts and commissions applicable to the Stock of Buyer) shall be paid by the Seller in connection with all Piggyback Registrations. Section 5.6 Primary Piggyback Registration. If a Piggyback Registration is an underwritten primary registration on behalf of the Seller, and the managing underwriters advise the Seller in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Seller, the Seller shall include in such registration (i) first, the securities the Seller proposes to sell, (ii) second, the Stock and any other securities requested to be included in such registration by holders entitled to registration rights in connection therewith, pro rata among such holders based on the number of shares requested to be included in such registration, and (iii) third, other securities requested to be included in such registration. Section 5.7 Secondary Piggyback Registration If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Seller's securities, and the managing underwriters advise the Sellers in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the holders initially requesting such registration, the Seller will include in such registration (i) first, the securities requested to be included therein by the holders requesting such registration, (ii) second, the Stock and any other securities requested to be included 21

in such registration by holders entitled to registration rights in connection therewith, pro rata among such holders based on the number of shares requested to be included in such registration, and (iii) third, other securities requested to be included in such registration. Section 5.8 Efforts. Whenever the holders of Stock have requested that any Stock be registered pursuant to this Agreement, the Seller shall use its reasonable best efforts to effect the registration and the sale of such Stock in accordance with the intended method of disposition. Section 5.9 Seller Indemnity. The Seller shall indemnify, to the extent permitted by Law, Buyer and the permitted assigns of the Stock , its officers and directors and each Person who controls such holder (within the meaning of the Securities Act) against all Losses caused by any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Seller by such holder expressly for use therein or by such holder's failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Seller has furnished such holder with a sufficient number of copies of the same. In connection with an underwritten offering, the Seller shall indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the holders of the Stock. Section 5.10 Information and Buyer Indemnity. In connection with any registration statement in which a holder is participating, Buyer shall furnish and shall cause each such holder to furnish to the Seller in writing such information and affidavits as the Seller reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by Law. Buyer shall indemnify the Seller, its directors and officers and each Person who controls the Seller (within the meaning of the Securities Act) against any Losses, resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by Buyer or the other holders, if any; provided that the obligation to indemnify shall be limited to the net amount of proceeds received by such holder from the sale of Stock pursuant to such registration statement. Section 5.11 (a) Third Party. In the event that any claim for which a Party providing indemnification hereunder (the "Indemnitor") would be liable to a Party entitled to indemnification hereunder (the "Indemnitee") is asserted against or sought to be collected from Indemnitee by a third party, Indemnitee shall promptly notify Indemnitor of such claim, specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim) (the "Claim Notice"). Indemnitor shall have fifteen (15) days from its receipt of the Claim Notice (the "Notice Period") to notify Indemnitee 22

(i) whether or not it disputes its liability to Indemnitee hereunder with respect to such claim, and (ii) if it does not dispute such liability, whether or not it desires, at its sole cost and expense, to defend Indemnitee against such claim; provided, however, that Indemnitee is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading which it shall deem necessary or appropriate to protect its interests. In the event that Indemnitor notifies Indemnitee within the Notice Period that it does not dispute such liability and desires to defend against such claim or demand, then, except as hereinafter provided, Indemnitor shall have the right to defend by appropriate proceedings, which proceedings shall be promptly settled or prosecuted to a final conclusion in such a manner as to avoid any risk of Indemnitee becoming subject to liability. If Indemnitee desires to participate in, but not control, any defense or settlement, it may do so at its own cost and expense. If Indemnitor disputes its liability with respect to such claim, or elects not to defend against such claim, whether by not giving timely notice as provided above or otherwise, Indemnitee shall have the right but not the obligation to defend against such claim, and the amount of any such claim, or if the same be contested by Indemnitor or by Indemnitee, then that portion thereof as to which such defense is unsuccessful, shall be conclusively deemed to be a liability of Indemnitor hereunder (subject, if it has timely disputed liability, to a determination as provided in Sections 5.11 and 7.12 that the disputed liability is covered by these indemnification provisions). (b) Party's Claim. In the event that Indemnitee shall have a claim against Indemnitor hereunder which does not involve a claim or demand being asserted against or sought to be collected from it by a third party, Indemnitee shall promptly send a Claim Notice with respect to such claim to Indemnitor. If Indemnitor does not notify Indemnitee within the Notice Period that it disputes such claim, the amount of such claim shall be conclusively deemed a liability of Indemnitor hereunder. (c) Disputed Claim. If Indemnitor shall notify Indemnitee during the Notice Period that it disputes any claim (the "Disputed Claim"), then the Disputed Claim shall be submitted to arbitration pursuant to the provisions of Section 7.12 of this Agreement.
