Gundersen, an individual with a residence address at 18 Harwich Street, Westwood, MA 02090 (the "Owner"). PRELIMINARY STATEMENT This Agreement contemplates a merger of a transitory subsidiary wholly-owned by Casella (the "Transitory Subsidiary") with and into AEI, with AEI being the surviving party in such merger. In such merger, the stockholders of AEI will receive Class A Common Stock of the Buyer in exchange for their shares of capital stock of AEI. It is contemplated that such merger will be accounted for under the pooling-of-interests method of accounting. This Agreement also contemplates that the Buyer will purchase, and the Owner will sell, all of his right, title and interest to the membership interest held by him in REP. NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth and other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereby agree as follows: I. THE ACQUISITION TRANSACTIONS. 1.1 Merger. (a) Upon and subject to the terms and conditions of this Agreement, the Transitory Subsidiary shall merge with and into AEI (with such merger referred to herein as the "Merger") at the Effective Time (as defined below). From and after the Effective Time, the separate corporate existence of the Transitory Subsidiary shall cease and AEI shall continue as the surviving corporation in the Merger (the "Surviving Corporation"). The "Effective Time" shall be the time at which the Surviving Corporation files Articles of Merger, in accordance with Section 78 of the Massachusetts Business Corporation Law (the "Articles of Merger"), with the Secretary of State of the Commonwealth of Massachusetts. The Merger shall have the effects set forth in Section 80 of the Massachusetts Business Corporation Law. At the Effective Time, by virtue of the Merger and without any action on the part of any Party or the holder of the capital stock of AEI, each share of common stock, without par value, of AEI ("Common Shares") issued and outstanding immediately prior to the Effective Time and Common Shares held in AEI's treasury) shall be converted into and represent the right to receive such number of shares of Class A common stock, $.01 par value per share, of the Buyer ("Buyer Common Stock") as is equal to the Conversion Ratio (as defined below). For purposes of this Agreement, (i) none of the shares of Buyer Common Stock issued hereunder will be registered under the Securities Act of 1933, as amended, and accordingly, all of such shares will constitute "restricted stock" for purposes of the Securities Act, and (ii) "Estimated Indebtedness" means the estimated aggregate Indebtedness of REP and AEI as of the Closing Date. (b) The "Conversion Ratio" shall be the result obtained by dividing an amount equal to (i) (X) the sum of (A) $14,107,500 plus (B) an amount equal to 5.0 times AEI's earnings before interest, taxes, depreciation and amortization ("EBITDA") (not including any contribution from REP other than payments for services rendered) for the 12-month period ended October 31, 1999, excluding expenses of AEI that will not be incurred following the Closing, minus (Y) the Estimated Indebtedness of AEI and REP as of the Closing, by (ii) the number of outstanding Common Shares immediately prior to the Effective Time, and dividing such amount by (iii) the lower of (A) the average of the closing prices of the Buyer Common Stock on the Nasdaq National Market over the ten trading days ending on the fifth trading day prior to the Closing, and (B) $17.00 per share (the "Buyer Closing Stock Price"). The Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock. Stockholders of record of AEI immediately prior to the Effective Time ("AEI Stockholders") shall be entitled to receive immediately 90% of the shares of Buyer Common Stock into which their AEI Shares were converted pursuant to this Section 1.1 (the "AEI Initial Shares"); the remaining 10% of the shares of Buyer Common Stock into which their AEI Shares were converted pursuant to this Section 1.1, rounded to the nearest whole number (the "AEI Escrow Shares"), shall be deposited in escrow pursuant to Section 1.4 and shall be held and disposed of in accordance with the terms of the Escrow Agreement. (c) Each AEI Share held in AEI's treasury immediately prior to the Effective Time shall be cancelled and retired without payment of any consideration therefor. (d) Each share of common stock, $.01 par value per share, of the Transitory Subsidiary issued and outstanding immediately prior to the Effective Time shall be converted into and thereafter evidence one share of common stock, $.01 par value per share, of the Surviving Corporation. (e) On the Closing Date, the Buyer shall deliver to each AEI Stockholder, upon presentation by the AEI Stockholder of the stock certificates (each, a "Certificate") representing all of the AEI Shares held by him, a stock certificate representing the Initial Shares issuable to such AEI Stockholder, as described in this Section 1.1, plus cash in lieu of any fractional shares, as provided in paragraph (h) below]. Until properly surrendered, each such Certificate shall be deemed for all purposes to evidence only the right to receive a certificate for the Initial Shares issuable pursuant to Section 1.1. Holders of Certificates shall not be entitled to receive certificates for the Initial Shares to which they would otherwise be entitled until such Certificates are properly surrendered. (f) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, the Buyer shall issue in exchange for such lost, stolen or destroyed Certificate the Initial Shares issuable in exchange therefor pursuant to Section 1.1 The Board of Directors of the Buyer may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to give the Buyer a bond in such sum as it may direct as indemnity against any claim that may be made against the Buyer with respect to the Certificate alleged to have been lost, stolen or destroyed. 7 (g) No dividends or other distributions that are payable to the holders of record of Buyer Common Stock as of a date on or after the Closing Date shall be paid to former AEI Stockholders entitled by reason of the Merger to receive Initial Shares until such holders surrender their Certificates for certificates representing the Merger Shares. Upon such surrender, the Buyer shall pay or deliver to the persons in whose name the certificates representing such Initial Shares are issued any dividends or other distributions that are payable to the holders of record of Buyer Common Stock as of a date on or after the Closing Date and which were paid or delivered between the Effective Time and the time of such surrender; provided that no such person shall be entitled to receive any interest on such dividends or other distributions (h) No certificates or scrip representing fractional Initial Shares shall be issued to former AEI Stockholders upon the surrender for exchange of Certificates, and such former Stockholders shall not be entitled to any voting rights, rights to receive any dividends or distributions or other rights as a stockholder of the Buyer with respect to any fractional Initial Shares that would have otherwise been issued to such former AEI Stockholders. In lieu of any fractional Initial Shares that would have otherwise been issued, each former AEI Stockholder that would have been entitled to receive a fractional Initial Share shall, upon proper surrender of such person's Certificates, receive such whole number of Initial Shares as is equal to the precise number of Initial Shares to which such person would be entitled, rounded up or down to the nearest whole number (with a fractional interest equal to .5 rounded to the nearest odd number). (i) The Certificate of Incorporation of the Surviving Corporation immediately following the Effective Time shall be the same as the Certificate of Incorporation of the Transitory Subsidiary immediately prior to the Effective Time, except that (1) the name of the corporation set forth therein shall be changed to the name of AEI and (2) the identity of the incorporator shall be deleted. (j) The By-laws of the Surviving Corporation immediately following the Effective Time shall be the same as the By-laws of the Transitory Subsidiary immediately prior to the Effective Time, except that the name of the corporation set forth therein shall be changed to the name of AEI. (k) At the Effective Time, the stock transfer books of AEI shall be closed and no transfer of AEI Shares shall thereafter be made. 1.2 PURCHASE OF THE MEMBERSHIP INTEREST FROM THE OWNER. Subject to and upon the terms and conditions of this Agreement, at the Closing, the Owner shall sell, transfer, convey, assign and deliver to [the Buyer], and [the Buyer] shall purchase, acquire and accept from the Owner, all of the Owner's right, title and interest in and to any membership interests in REP, including without limitation, any and all interest in capital, profits, loans or otherwise (the "LLC Interest"). At the Closing the Owner shall deliver to the Buyer an assignment of the REP interest, together with an amendment to the Operating Agreement of REP, each in the form of EXHIBIT A attached hereto. As consideration for the sale of the LLC Interest to the Buyer, the Buyer shall issue to the Owner such number of shares of Buyer Common Stock as is equal to the result obtained by dividing an amount equal to (i) $142,500 by (ii) the Buyer Closing Stock Price. The Owner shall be entitled to receive immediately 90% of the shares of Buyer Common Stock payable pursuant to the preceding sentence (the "LLC Interest Initial Shares"); the 8 remaining 10% of the shares of Buyer Common Stock payable pursuant to the preceding sentence, rounded to the nearest whole number (the "LLC Interest Escrow Shares"), shall be deposited in escrow pursuant to Section 1.4 and shall be held and disposed of in accordance with the terms of the Escrow Agreement. The AEI Initial Shares and the LLC Interest Initial Shares are collectively referred to as the "Initial Shares", and the AEI Escrow Shares and the LLC Interest Escrow Shares shall together be referred to herein as the "Escrow Shares." The Initial Shares and the Escrow shares shall together be referred to herein as the "Merger Shares". The Merger and the purchase of the LLC Interest herein shall be conditioned on each other, and neither party shall be obligated to close the Merger or the purchase of the LLC Interest unless both such transactions shall close simultaneously. 1.3 FURTHER ASSURANCES. At any time and from time to time after the Closing, at the Buyer's request and without further consideration, AEI and the Owner promptly shall execute and deliver such instruments of sale, transfer, conveyance, assignment and confirmation, and take such other action, as the Buyer may reasonably request to more effectively assist them in exercising all rights with respect hereto and to carry out the purpose and intent of this Agreement. 1.4 ESCROW. (a) On the Closing Date, the Buyer shall deliver to State Street Bank & Trust Company, as escrow agent (the "Escrow Agent") a certificate (issued in the name of the Escrow Agent or its nominee) representing the Escrow Shares for the purpose of securing the indemnification obligations of the AEI Stockholders and the Owner set forth in this Agreement. The Escrow Shares shall be held by the Escrow Agent under the Escrow Agreement pursuant to the terms thereof. The Escrow Shares shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any party, and shall be held and disbursed solely for the purposes and in accordance with the terms of the Escrow Agreement. (b) The adoption of this Agreement and the approval of the Merger by the AEI Stockholders shall constitute approval of this Agreement, the Escrow Agreement and of all of the arrangements relating hereto and thereto, including without limitation the placement of the Escrow Shares in escrow and the appointment of the Owner as the Indemnification Representative. 1.5 THE CLOSING. The parties are contemplating that a closing of the transactions described in Section 1.1 and 1.2 above shall take place at the offices of Hale and Dorr LLP, 60 State Street, Boston, Massachusetts at 10:00 a.m., Boston time, on or about January 15, 1999 or at such other place, time or date as may be mutually agreed upon in writing by the parties hereto. The Effective Time and the assignment of the LLC Interest by the Owner to the Buyer shall be deemed to occur at 9:00 a.m., Boston time, on the date of the Closing (the "Closing Date"). 1.6 POST CLOSING ADJUSTMENTS TO CONFIRM INDEBTEDNESS AND WORKING CAPITAL. The Initial Purchase Price shall be subject to adjustment after the Closing Date as follows: 9 (a) Within thirty (30) days following the Closing Date, AEI and the Owner shall cause Liberfarb and Sussman, independent accountants for the AEI Stockholders (the "AEI Accountants"), to conduct a SARS review of the books and records of AEI and REP as of the Closing Date. AEI and the Owner shall cause the AEI Accountants to deliver a reviewed balance sheet for each of AEI and REP (the "Closing Balance Sheets") to each of the Parties. The Closing Balance Sheets shall be prepared in accordance with generally accepted accounting principles applied consistently with AEI's past practice, without any adjustments applicable solely as a result of the transactions contemplated by this Agreement. The Closing Balance Sheets shall reflect any Indebtedness (as defined below) which is repaid at the Closing as if it had not been repaid, and any cash used to pay same as if it had not been so used. (b) The Closing Balance Sheets (also referred to as the "Closing Financial Statements") delivered pursuant to the preceding paragraph shall be accompanied by a statement prepared by the AEI Accountants, setting forth the aggregate Indebtedness and aggregate Working Capital of AEI and REP as of the Closing. For purposes of this Agreement, "Indebtedness" means (x) all liabilities as are required to be listed on a balance sheet under generally accepted accounting principles, plus (y) any expenses of REP and/or AEI incurred in connection with the transactions contemplated by this Agreement. In the event that (A) the Buyer or (B) AEI disputes the Closing Financial Statements or the calculation of the amount of Indebtedness or Working Capital, the disputing party shall notify the other parties hereto in writing (the "Dispute Notice") of the amount, nature and basis of such dispute, within 20 calendar days after delivery of the Closing Financial Statements. In the event of such a dispute, the parties hereto shall first use their best efforts to resolve such dispute among themselves. If the parties are unable to resolve the dispute within 10 calendar days after the delivery of the Dispute Notice, the dispute shall be submitted to the AEI Accountants and to Arthur Andersen LLP, independent accountants for the Buyer (Arthur Andersen LLP being referred to as the "Buyer Accountants"), for resolution. The Buyer Accountants and the AEI Accountants shall use their best efforts to resolve the dispute within 30 days after submission. If they are unable to agree upon a resolution of the dispute within such 30-day period, the dispute shall be submitted to the American Arbitration Association for resolution within not more than 60 days in accordance with procedures established by the American Arbitration Association in their sole discretion. The determination of either the Buyer Accountants and the AEI Accountants, on the one hand, or the American Arbitration Association, on the other hand, as to the resolution of any dispute shall be final and binding and conclusive upon all parties hereto. All determinations pursuant to this paragraph (c) shall be in writing and shall be delivered to the parties hereto. For all purposes of this Agreement, the term "Closing Financial Statements" shall mean the Closing Financial Statements as modified pursuant to this Section 1.6. (c) The fees and expenses of the AEI Accountants in connection with the preparation of the Closing Financial Statements and the fees and expenses of the Buyer Accountants in connection with the resolution of disputes pursuant to paragraph (c) above shall be borne by the Buyer, and the fees and expenses of the AEI Accountants in connection with the resolution of disputes pursuant to paragraph (c) above shall be borne by the AEI Stockholders, jointly and severally. The fees and expenses of the American Arbitration Association in connection with the resolution of disputes pursuant to paragraph (c) above shall be shared equally by the Buyer on the one hand, and by the AEI Stockholders and the Owner, jointly and severally on the other hand. 10 (d) Immediately upon the expiration of the 20-day period for giving the Dispute Notice, if no Dispute Notice is given, or immediately upon the resolution of disputes, if any, pursuant to subparagraph (c) above (as applicable, the "Indebtedness Adjustment Date"), the AEI Stockholders and the Owner shall, jointly and severally, deliver to the Buyer such number of shares of Buyer Common Stock as is equal to the quotient resulting from dividing (A) the amount by which the aggregate Indebtedness of AEI and REP as shown on the Closing Balance Sheet is greater than the aggregate Estimated Indebtedness of AEI and REP at the Closing, plus the amount by which the aggregate working capital of AEI and REP is less than the aggregate working capital of AEI and REP as of September 30, 1999 less any cash (the "Working Capital Target") (provided that if the aggregate working capital of AEI and REP is greater than the Working Capital Target, it shall not be applied to reduce the amount by which the aggregate Indebtedness is greater than the aggregate Estimated Indebtedness, and if the aggregate Indebtedness is less than the aggregate Estimated Indebtedness at the Closing, it shall not be applied to reduce the amount by which the aggregate working is less than the Working Capital Target) by (B) the Buyer Closing Stock Price. In the event that the aggregate Indebtedness as finally reflected on the Closing Financial Statements is less than the aggregate Estimated Indebtedness, and the working capital as finally reflected on the Closing Financial Statements is not less than the Working Capital Target, then the Buyer shall issue such additional number of shares of Buyer Common Stock to the AEI Stockholders and the Owner as is equal to the amount by which such aggregate Indebtedness exceeds the Estimated Indebtedness, divided by the Buyer Closing Stock Price. The allocation of such additional shares among the AEI Stockholders and the Owner shall be determined by the Buyer and the Owner, individually and in his capacity as Indemnification Representative, in their reasonable judgment. II. REPRESENTATIONS OF AEI AND THE OWNER. AEI, REP and the Owner jointly and severally represent and warrant as follows to the Buyer, except as set forth in the disclosure schedule provided by AEI and the Owner to the Buyer on the date hereof and accepted in writing by the Buyer (the "Disclosure Schedule") (it being understood that all references in this Section 2 to AEI shall be deemed to include REP, unless the context otherwise requires).

The AEI Stockholders and the Owner, jointly and severally, further agree to indemnify and hold harmless the Buyer and its affiliates from any and all claims, damages, losses, liabilities, costs and expenses (including, without limitation, settlement costs and any legal, accounting or other expenses for investigating or defending any actions or threatened actions) reasonably incurred by the Buyer in connection with each and all of the following: (a) Any violation prior to the Closing by AEI or REP of, or any failure prior to the Closing by AEI or REP to comply with, any law, ruling, order, decree, regulation or zoning, environmental or permit requirement applicable to AEI, REP or the Assets or their businesses, whether or not any such violation or failure to comply has been disclosed to the Buyer, including only any costs incurred by the Buyer in order to bring the Assets into compliance with environmental laws as a consequence of noncompliance with such laws on the Closing Date (but not including up to $150,000 in capital expenditures required to be incurred for purposes of complying with DEP Administrative Consent Order ACOP-99-4004); (b) Any tax liabilities or obligations of AEI, the Owner or REP relating to the period prior to the Closing; (c) Any claims against, or liabilities or obligations of, AEI with respect to obligations under Employee Plans relating to the period prior to the Closing; (d) any failure of any AEI Stockholder to have good, valid and marketable title to the issued and outstanding AEI Shares issued in the name of such AEI Stockholder, free and clear of all Encumbrances, or any failure of the Owner to have good, valid and marketable title to the LLC Interest, free and clear of all Encumbrances; and (e) any claim by a stockholder or former stockholder of AEI, or any member or former member of REP, or other person or entity, seeking to assert, or based upon: (i) ownership or rights to ownership of any shares of stock of AEI or to any equity in REP; (ii) any rights of a stockholder or member (other than the right to receive the Merger Shares pursuant to this Agreement or appraisal rights under the applicable provisions of the Massachusetts Business Corporation Law), including any option, preemptive rights or rights to notice or to vote; (iii) any rights under the Articles of Organization or By-laws of AEI or under the operating agreements of REP; or (iv) any claim that his, her or its shares or equity interest were wrongfully repurchased by AEI or REP. 9.3 CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for indemnification hereunder, the party seeking indemnification (the "Indemnified Party") shall promptly notify the party from whom indemnification is sought (the "Indemnifying Party") of the claim and, when known, the facts constituting the basis for such claim. In the event of any such claim for indemnification hereunder resulting from or in connection with any claim or legal proceedings by a third-party, the notice to the Indemnifying Party shall specify, if known, the amount or an estimate of the amount of the liability arising therefrom. The Indemnified Party shall not settle 39 or compromise any claim by a third party for which it is entitled to indemnification hereunder without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, unless suit shall have been instituted against it and the Indemnifying Party shall not have taken control of such suit after notification thereof as provided in Subsection 9.4 of this Agreement. The Indemnifying Party shall not settle or compromise any claim by a third party without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld. 9.4 DEFENSE BY INDEMNIFYING PARTY. In connection with any claim giving rise to indemnity hereunder resulting from or arising out of any claim or legal proceeding by a person who is not a party to this Agreement, the Indemnifying Party at its sole cost and expense may, upon written notice to the Indemnified Party, assume the defense of any such claim or legal proceeding if it acknowledges to the Indemnified Party in writing its obligations to indemnify the Indemnified Party with respect to all elements of such claim. The Indemnified Party shall be entitled to participate in (but not control) the defense of any such action, with its counsel and at its own expense. If the Indemnifying Party does not assume the defense of any such claim or litigation resulting therefrom within 30 days after the date such claim is made, (a) the Indemnified Party may defend against such claim or litigation, in such manner as it may deem appropriate, including, but not limited to, settling such claim or litigation, after giving notice of the same to the Indemnifying Party, on such terms as the Indemnified Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to participate in (but not control) the defense of such action, with its counsel and at its own expense. If the Indemnifying Party thereafter seeks to question the manner in which the Indemnified Party defended such third party claim or the amount or nature of any such settlement, the Indemnifying Party shall have the burden to prove by a preponderance of the evidence that the Indemnified Party did not defend or settle such third party claim in a reasonably prudent manner. 9.5 PAYMENT OF INDEMNIFICATION OBLIGATION. Any claim for indemnification by the Buyer under this Section 9 shall be made first against the Escrow Account for Escrow Shares having a value equal to the Damages (as determined pursuant to the Escrow Agreement), and, to the extent the Escrow Account is insufficient to cover the indemnification obligations of the AEI Stockholders and the Owner hereunder, shall be paid by the delivery to the Buyer of shares of Buyer Common Stock held by such indemnifying parties, having a value per share equal to the Buyer Closing Stock Price. 9.6 SURVIVAL OF REPRESENTATIONS; CLAIMS FOR INDEMNIFICATION. All representations and warranties made by the parties herein or in any instrument or document furnished in connection herewith shall survive the Closing and any investigation at any time made by or on behalf of the parties hereto. All such representations and warranties shall expire on first anniversary of the Closing Date. All claims and actions for indemnity pursuant to this Section 9 for breach of any representation or warranty shall be specifically asserted or maintained in writing by a party hereto on or prior to the first anniversary of the Closing Date, except for claims, if any, specifically asserted in writing prior to such date, which shall survive until finally resolved and satisfied in full. Notwithstanding anything to the contrary in this Section 9, (I) no indemnified party shall be entitled to receive, and no indemnifying party shall be obligated to pay, the first $50,000 in the aggregate of indemnity obligations otherwise payable by the AEI Stockholders and Owner, on the one hand, or Buyer, on the other hand, pursuant to Section 9.1(a) or 9.1(c) 40 above; and (ii) in no event shall the aggregate liability of the AEI Stockholders and the Owner hereunder exceed the Merger Shares received by them hereunder. Except with respect to claims based on fraud, in the event the Closing occurs, the rights of the indemnified persons under this Article IX shall be the exclusive remedy of the indemnified persons with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement of the Buyer, AEI, the Owner or REP contained in this Agreement. 9.7 INDEMNIFICATION REPRESENTATIVE. The Indemnification Representative shall have full power and authority on behalf of each AEI Stockholder to take any and all actions on behalf of, execute any and all instruments on behalf of, and execute or waive any and all rights of, the AEI Stockholders under this Article IX. The Indemnification Representative shall have no liability to any AE Stockholder for any action taken or omitted on behalf of the AEI Stockholders pursuant to this Article IX. Robert S. Gundersen shall be the Indemnification Representative; provided that, if he declines or is unable to so serve, the Indemnification Representative shall be selected by the remaining former AEI Stockholders in proportion to their interest in AEI immediately preceding the Closing. X. POST-CLOSING AGREEMENTS. AEI and the Owner agree that from and after the Closing Date: 10.1 PROPRIETARY INFORMATION. (a) The AEI Stockholders and the Owner shall hold in confidence, and use their best efforts to have all of their officers, directors and personnel hold in confidence, all knowledge and information of a secret or confidential nature with respect to the business of AEI and REP and shall not disclose, publish or make use of the same without the consent of the Buyer, except to the extent that such information shall have become public knowledge other than by breach of this Agreement by AEI or the Owner. (b) The AEI Stockholders and the Owner agree that the remedy at law for any breach of this Subsection 10.1 would be inadequate and that the Buyer shall be entitled to injunctive relief in addition to any other remedy it may have upon breach of any provision of this Subsection 10.1. 10.2 NO SOLICITATION OR HIRING OF FORMER EMPLOYEES. Except as provided by law, for a period of five years after the Closing Date, the Owner shall not solicit any person who was an employee of AEI or REP on the Closing Date to terminate his employment with the Buyer or its affiliates or to become an employee of the Owner or any of his affiliates or hire any person who was such an employee on the date hereof or on the Closing Date. 10.3 NON-COMPETITION AGREEMENT. (a) For a period of five years after the Closing Date, neither the Owner nor any affiliate thereof that is not a natural person shall engage in any business competitive with the business of AEI or REP as conducted on the date hereof or on the Closing Date within a 125-mile radius of any facility of the Buyer or any affiliate of the Buyer. Without limiting the generality of the foregoing, the Owner's ownership and operation of the Tamworth, NH biomass 41 power plant, as such operation is conducted on the date hereof, shall be deemed not to be competitive with the business of AEI or REP for purposes of the preceding sentence. (b) The parties hereto agree that the duration and geographic scope of the non-competition provision set forth in this Subsection 10.3 are reasonable. In the event that any court determines that the duration or the geographic scope, or both, are unreasonable and that such provision is to that extent unenforceable, the parties hereto agree that the provision shall remain in full force and effect for the greatest time period and in the greatest area that would not render it unenforceable. The parties intend that this non-competition provision shall be deemed to be a series of separate covenants, one for each and every county of each and every state of the United States of America and each and every political subdivision of each and every country outside the United States of America where this provision is intended to be effective. The AEI Stockholders and the Owner agree that damages are an inadequate remedy for any breach of this provision and that the Buyer shall, whether or not it is pursuing any potential remedies at law, be entitled to equitable relief in the form of preliminary and permanent injunctions without bond or other security upon any actual or threatened breach of this non-competition provision. 10.4 COOPERATION IN LITIGATION. Each party hereto will fully cooperate with the other in the defense or prosecution of any litigation or proceeding already instituted or which may be instituted hereafter against or by such party relating to or arising out of the conduct of the business of AEI or REP prior to or after the Closing Date (other than litigation arising out the transactions contemplated by this Agreement). The party requesting such cooperation shall pay the out-of-pocket expenses (including legal fees and disbursements) of the party providing such cooperation and of its officers, directors, employees and agents reasonably incurred in connection with providing such cooperation, but shall not be responsible to reimburse the party providing such cooperation for such party's time spent in such cooperation or the salaries or costs of fringe benefits or similar expenses paid by the party providing such cooperation to its officers, directors, employees and agents while assisting in the defense or prosecution of any such litigation or proceeding. 10.5 RIGHT OF FIRST REFUSAL AGREEMENT. The Owner hereby agrees, on his own behalf and on behalf of his affiliates, that the Buyer and its affiliates shall have the right to [purchase] up to all of the [disposal] capacity of the Tamworth biomass power plant; provided, however, that the Buyer shall pay a tipping fee therefor equal to the prevailing market rate of comparable disposal capacity in the [Greater Boston metropolitan area]. The Owner agrees, on his own behalf and on behalf of his affiliates, that any transfer of his or their interest in the Tamworth biomass power plant shall be expressly subject to the prior sentence, and that any transfer in violation thereof be and hereby is void. XI. TERMINATION OF AGREEMENT. 11.1 TERMINATION BY LAPSE OF TIME. This Agreement shall terminate at 5:00 p.m., Boston time, on January 31, 2000 if the transactions contemplated hereby have not been consummated, unless such date is extended by the written consent of all of the parties hereto; provided, however, that if a filing is required to be made under the Hart-Scott-Rodino Antitrust Improvements Act with respect to the transactions contemplated by this Agreement, then the date on which this Agreement shall terminate shall automatically be extended by a period of up to 45 42 days after the filing thereof; provided that both Buyer on the one hand and AEI and the Owner on the other hand shall use commercially reasonable efforts to make any such filing as promptly as possible after the date of this Agreement. 11.2 TERMINATION BY AGREEMENT OF THE PARTIES. This Agreement may be terminated by the mutual written agreement of the parties hereto. In the event of such termination by agreement, no party shall have any further obligation or liability to any other party under this Agreement. 11.3 TERMINATION BY REASON OF BREACH. This Agreement may be terminated by AEI, REP and the Owner, on the one hand, if at any time prior to the Closing there shall occur a material breach of any of the representations, warranties or covenants of the Buyer or the Transitory Subsidiary, or the material failure by the Buyer or the Transitory Subsidiary to perform any condition or obligation hereunder, and may be terminated by the Buyer or the Transitory Subsidiary, on the other hand, if at any time prior to the Closing there shall occur a material breach of any of the representations, warranties or covenants of AEI, REP or the Owner or the failure of AEI, REP or the Owner to perform any condition or obligation hereunder. XII. BROKERS. 12.1 FOR AEI, THE OWNER AND REP. AEI and the Owner jointly and severally represent and warrant that they have not engaged any broker or finder (other than Stephen D. Devito) or incurred any liability for brokerage fees, commissions or finder's fees in connection with the transactions contemplated by this Agreement. The Owner agrees to pay all fees, expenses and other compensation owed to Stephen D. Devito.

The Buyer shall file with the SEC, within 30 days following the Closing, a registration statement on Form S-3 covering the resale to the public by the AEI Stockholders and the Owner of the Merger Shares (the "Stockholder Registration Statement"). The Buyer shall use its best efforts to cause the Stockholder Registration Statement to be declared effective by the SEC as soon as practicable, PROVIDED that the Stockholder Registration Statement shall not be declared effective until after financial results covering at least 30 days of combined operations of AEI and the Buyer after the Effective Time shall have been publicly released.

(b) If the Buyer delays or suspends the Stockholder Registration Statement or requires the AEI Stockholders to cease sales of shares pursuant to paragraph (a) above, the Buyer shall, as promptly as practicable following the termination of the circumstance which entitled the Buyer to do so, take such actions as may be necessary to file or reinstate the effectiveness of the Stockholder Registration Statement and/or give written notice to all AEI Stockholders authorizing them to resume sales pursuant to the Stockholder Registration Statement. If as a result thereof the prospectus included in the Stockholder Registration Statement has been amended to comply with the requirements of the Securities Act, the Buyer shall enclose such revised prospectus with the notice to AEI Stockholders given pursuant to this paragraph (b), and the AEI Stockholders shall make no offers or sales of shares pursuant to the Stockholder Registration Statement other than by means of such revised prospectus. 13.3 REGISTRATION PROCEDURES.

(c) If the Buyer has delivered preliminary or final prospectuses to the AEI Stockholders and after having done so the prospectus is amended or supplemented to comply with the requirements of the Securities Act, the Buyer shall promptly notify the AEI Stockholders and, if requested by the Buyer, the AEI Stockholders shall immediately cease making offers or sales of shares under the Stockholder Registration Statement and return all 44 prospectuses to the Buyer. The Buyer shall promptly provide the AEI Stockholders with revised or supplemented prospectuses and, following receipt of the revised or supplemented prospectuses, the AEI Stockholders shall be free to resume making offers and sales under the Stockholder Registration Statement.

The Buyer shall have the right to assume the defense and settlement of any claim or suit for which the Buyer may be responsible for indemnification under this Section 13.5. 13.6 ASSIGNMENT OF RIGHTS.

Section 1.1(b) is hereby amended and restated as follows: (b) The "Conversion Ratio" shall be the result obtained by dividing an amount equal to (i) (X) the sum of (A) $14,688,330 plus (B) an amount equal to 5.0 times AEI's earnings before interest, taxes, depreciation and amortization (not including any contribution from REP other than payments for services rendered) for the 12-month period ended October 31, 1999, excluding expenses of AEI that will not be incurred following the Closing ("EBITDA"), minus (Y) the Estimated Indebtedness of AEI and REP as of the Closing, by (ii) the number of outstanding Common Shares immediately prior to the Effective Time, and dividing such amount by (iii) 15.3125 per share (the "Buyer Closing Stock Price"). The Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock. Stockholders of record of AEI immediately prior to the Effective Time ("AEI Stockholders") shall be entitled to receive immediately 90% of the shares of Buyer Common Stock into which their AEI Shares were converted pursuant to this Section 1.1 (the "AEI Initial Shares"); the remaining 10% of the shares of Buyer Common Stock into which their AEI Shares were converted pursuant to this Section 1.1, rounded to the nearest whole number (the "AEI Escrow Shares"), shall be deposited in escrow pursuant to Section 1.4 and shall be held and disposed of in accordance with the terms of the Escrow Agreement. 2. Section 1.6 is hereby amended and restated as follows: (a) Within thirty (30) days following the Closing Date, AEI and the Owner shall cause Liberfarb and Sussman, independent accountants for the AEI Stockholders (the "AEI Accountants"), to conduct a SARS review of the books and records of AEI and REP as of the Closing Date. AEI and the Owner shall cause the AEI Accountants to deliver a reviewed balance sheet for each of AEI and REP (the "Closing Balance Sheets") to each of the Parties. The Closing Balance Sheets shall be prepared in accordance with generally accepted accounting principles applied consistently with AEI's past practice, without any adjustments applicable solely as a result of the transactions contemplated by this Agreement. The Closing Balance Sheets shall reflect any Indebtedness (as defined below) which is repaid at the Closing as if it had not been repaid, and any cash used to pay same as if it had not been so used. In addition, within thirty (30) days following the Closing Date, the Buyer will review the "AEI Statement of Operations for the twelve months ended 10/31/99 (with adjustments)", as previously delivered by AEI to the Buyer and attached hereto as SCHEDULE D. (b) The Closing Balance Sheets (also referred to as the "Closing Financial Statements") delivered pursuant to the preceding paragraph shall be accompanied by a statement prepared by the AEI Accountants, setting forth the aggregate Indebtedness and aggregate Working Capital of AEI and REP as of the Closing. For purposes of this Agreement, "Indebtedness" means (x) all liabilities as are required to be listed on a balance sheet under generally accepted accounting principles, plus (y) any expenses of REP and/or AEI incurred in connection with the transactions contemplated by this Agreement, including, without limiting the foregoing, all amounts which are paid or payable in connection with any employment agreement to which AEI or REP and/or is party, including upon the termination of such employment agreements or the determination that the transactions contemplated by this Agreement constitute a sale or otherwise entitle the employee to a payment under such employment agreements. In the event that (A) the Buyer or (B) AEI disputes the Closing Financial Statements or the calculation of the amount of Indebtedness or Working Capital, or in the event that the Buyer disputes that the EBITDA was at least $1,435,023, the disputing party shall notify the other parties hereto in writing (the "Dispute Notice") of the amount, nature and basis of such dispute, within 20 calendar days after delivery of the Closing Financial Statements. In the event of such a dispute, the parties hereto shall first use their best efforts to resolve such dispute among themselves. If the parties are unable to resolve the dispute within 10 calendar days after the delivery of the Dispute Notice, the dispute shall be submitted to the AEI Accountants and to Arthur Andersen LLP, independent accountants for the Buyer (Arthur Andersen LLP being referred to as the "Buyer Accountants"), for resolution. The Buyer Accountants and the AEI Accountants shall use their best efforts to resolve the dispute within 30 days after submission. If they are unable to agree upon a resolution of the dispute within such 30-day period, the dispute shall be submitted to the American Arbitration Association for resolution within not more than 60 days in accordance with procedures established by the American Arbitration Association in their sole discretion. The determination of either the Buyer Accountants and the AEI Accountants, on the one hand, or the American Arbitration Association, on the other hand, as to the resolution of any dispute shall be final and binding and conclusive upon all parties hereto. All determinations pursuant to this paragraph (c) shall be in writing and shall be delivered to the parties hereto. For all purposes of this Agreement, the term "Closing Financial Statements" and "EBITDA" shall mean the Closing Financial Statements and EBITDA as modified pursuant to this Section 1.6. (c) The fees and expenses of the AEI Accountants in connection with the preparation of the Closing Financial Statements and the fees and expenses of the Buyer Accountants in connection with the resolution of disputes pursuant to paragraph (c) above shall be borne by the Buyer, and the fees and expenses of the AEI Accountants in connection with the resolution of disputes pursuant to paragraph (c) above shall be borne by the AEI Stockholders, jointly and severally. The fees and expenses of the American Arbitration Association in connection with the resolution of disputes pursuant to paragraph (c) above shall be shared equally by the Buyer on the one hand, and by the AEI Stockholders and the Owner, jointly and severally on the other hand. (d) Immediately upon the expiration of the 20-day period for giving the Dispute Notice, if no Dispute Notice is given, or immediately upon the resolution of disputes, if any, pursuant to subparagraph (c) above (as applicable, the "Indebtedness Adjustment Date"), the AEI Stockholders and the Owner shall, jointly and severally, deliver to the Buyer such number of shares of Buyer Common Stock as is equal to the quotient resulting from dividing (A) (x) the amount by which the aggregate Indebtedness of AEI and REP as shown on the Closing Balance Sheet is greater than the aggregate Estimated Indebtedness of AEI and REP at the Closing, plus (y) the amount by which the aggregate working capital of AEI and REP is less than the aggregate working capital of AEI and REP as of September 30, 1999 less any cash (the "Working Capital Target"), plus (z) five times the amount by which EBITDA is less than $1,435,023 (provided that if (i) the aggregate working capital of AEI and REP is greater than the Working Capital Target, (ii) the aggregate Indebtedness is less than the aggregate Estimated Indebtedness, or (iii) EBITDA is greater than $1,435,023, it shall not be applied to reduce the amount by which any of (x), (y) or (z) is true) by (B) the Buyer Closing Stock Price. In the event that the aggregate Indebtedness as finally reflected on the Closing Financial Statements is less than the aggregate Estimated Indebtedness, the working capital as finally reflected on the Closing Financial Statements is not less than the Working Capital Target, and EBITDA is not less than $1,435,023, then the Buyer shall issue such additional number of shares of Buyer Common Stock to the AEI Stockholders and the Owner as is equal to the amount by which such aggregate Indebtedness exceeds the Estimated Indebtedness, divided by the Buyer Closing Stock Price. The allocation of such additional shares among the AEI Stockholders and the Owner shall be determined by the Buyer and the Owner, individually and in his capacity as Indemnification Representative, in their reasonable judgment. 3. A new Section 2.26(m) is hereby added which shall read as follows: "(m) Such Real Estate abuts on and has direct vehicular access to a public road or access to a public road via a permanent, irrevocable, appurtenant easement benefiting such Real Estate." 4. The following paragraphs shall be inserted immediately after Section 9.12(e): "(f) any claims against, or liabilities, obligations or expenses of, AEI or REP with respect to any litigation, arbitration or similar proceeding or dispute resolution naming such party and in existence on the date hereof regardless of whether such matter has been listed on a disclosure schedule; and (g) all amounts payable under any outstanding payable or other obligation of AEI or REP which become due as a result of the transactions contemplated by this Agreement (to the same such amounts have not been included within the meaning of "Indebtedness" above)" 5. The last word in Section 9.2(d), "and", shall be deleted. 6. The period in Section 9.2(e) shall be deleted and a semicolon inserted in lieu thereof. 7. Section 9.6 is hereby deleted, and the following shall be inserted in lieu thereof: "Section 9.6 SURVIVAL OF REPRESENTATIONS; CLAIMS FOR INDEMNIFICATION. All representations and warranties made by the parties herein or in any instrument or document furnished in connection herewith shall survive the Closing and any investigation at any time made by or on behalf of the parties hereto. All such representations and warranties shall expire on the first anniversary of the Closing Date. All claims and actions for indemnity pursuant to this Section 9 for breach of any representation or warranty shall be specifically asserted or maintained in writing by a party hereto on or prior to the first anniversary of the Closing Date (provided, however, that without limiting the foregoing, the provisions of Section 9.1(b) and 9.2(a) through (g) shall not be subject to such limitations) except for claims, if any, specifically asserted in writing prior to such date, which shall survive until finally resolved and satisfied in full. Notwithstanding anything to the contrary in this Section 9, (i) no indemnified party shall be entitled to receive, and no indemnifying party shall be obligated to pay, the first $50,000 in the aggregate of indemnity obligations otherwise payable by the AEI Stockholders and Owner, on the one hand, or Buyer, on the other hand, pursuant to Section 9.1(a) or 9.1(c) above; and (ii) in no event shall the aggregate liability of the AEI Stockholders and the Owner hereunder exceed the Merger Shares received by them hereunder, except in the event such liability is the result of a claim brought pursuant to Section 9.2(f) or 9.2(g), in which case such aggregate liability may exceed the Merger Shares received by the AEI Stockholders and the Owner. Except with respect to claims based on fraud, in the event the Closing occurs, the rights of the indemnified persons under this Article IX shall be the exclusive remedy of the indemnified persons with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement of the Buyer, AEI, the Owner or REP contained in this Agreement. 8. In all other respects, the Agreement shall remain in full force and effect, and all references in the Agreement to "this Agreement" shall mean the Agreement as amended hereby. [remainder of page intentionally left blank] IN WITNESS WHEREOF, this Agreement has been duly executed by the parties hereto as of and on the date first above written.
