PURCHASE

Section 2.01. Sale and Purchase of Membership Interest.

(a) Subject to the terms and conditions set forth in this Agreement, the Partnership shall purchase and the Seller shall sell, assign, transfer and convey the Membership Interest in one or more of the Project Companies. The Purchase Price of the Membership Interest in each Project Company shall include two components: (1) the Initial Payment, which shall be payable in one installment, which shall be payable in accordance with paragraph (d) below, and (2) Contingent Payments due on each Quarterly Payment Date through and including the Quarterly Payment Date which follows the Calendar Quarter ended on December 31, 2007 and on the Final Adjustment Date.

(b) The Partnership shall purchase the Membership Interest in the Project Companies and shall exercise such right on June 29, 1998.

(c) Subject to the terms and conditions of this Agreement, at the Closing with respect to the sale of the Membership Interest in a Project Company, the Seller will sell, assign, transfer and convey all of the Seller’s rights, title and interest in the Membership Interest in such Project Company to the Partnership and take such action as shall be required to cause the Partnership to be admitted as the sole Member of each such Purchased Company, and the Partnership will purchase, assume and accept the Membership Interest from the Seller and will pay, in full, the Initial Payment and all of the Contingent Payments as they become due for the Membership Interest in such Project Company. On the Closing Date with respect to the purchase of the Membership Interest in a Project Company, all right, title and interest of the Seller in the Membership Interest in such Project Company shall be transferred, assigned and conveyed to the Partnership, the Partnership shall be admitted as the sole Member of such Project Company and all interest of the Seller in the Membership Interest and in the Purchased Company shall be released by the Seller.

(d) On the Closing Date, with respect to the Membership Interest in each Project Company purchased on such date, the Partnership shall pay in full and in immediately available funds the Initial Payment in the amount of $1,500,000.

(e) The Partnership shall, as further consideration for each Membership Interest purchased hereunder, be required to make and agrees to make Contingent Payments to the Seller in the amounts set forth in this Section 2.01(e). The Contingent Payments shall be due and payable on each Quarterly Payment Date and on the Final Adjustment Date. The Contingent Payments in respect of the Membership Interest in a given Project shall commence on the Quarterly Payment Date immediately following the Calendar Quarter in which the first Qualified Fuel produced by such Project is sold and end with the Final Adjustment Date. Subject to Article IX hereof, with respect to each Calendar Quarter, the Contingent Payment due on the Quarterly Payment Date immediately following such Calendar Quarter shall be an amount equal to (i) fifty percent (50)% of the aggregate Estimated Tax Credits generated by Projects during that portion of such Calendar Quarter when the respective Project Companies were Purchased Companies and (ii) with respect to the Contingent Payment due on the Adjustment Date, plus or minus the product of (x) fifty percent (50)% multiplied by (y) the Annual Adjustment Amount. The term “Estimated Tax Credits,” for any Calendar Quarter, as used in this Agreement, means the sum of the Tax Credits, as in accordance with Section 3.1(e) of the Partnership Agreement; and, as adjusted following review by the Seller as provided herein and by the Partners’ Accountant as provided in Section 3.1(f) of the Partnership Agreement. Notwithstanding the foregoing, the Seller agrees that the Partnership shall not be in

default under this Agreement in respect of its failure to make any Contingent Payment for the Membership Interest in a Project Company (x) unless and until the date the conditions set forth in Section 3.1(g) in the Partnership Agreement have been satisfied or waived, and (y) unless all Contingent Payments due on or prior to such date have not been paid in full (subject to the other provisions of this Agreement) within five days after such date.

(f) The final Contingent Payment shall be due on the Final Adjustment Date and shall be in the amount of the Final Adjustment Amount if such Final Adjustment Amount is a positive amount.

(g) The General Partner shall prepare its calculation of the Estimated Tax Credits and the Contingent Payment for each Calendar Quarter at the same time that the General Partner prepares its calculation of the amount of the Quarterly Contribution as provided in Section 3.1(e) of the Partnership Agreement and shall submit a report showing the Partnership’s determination of the Contingent Payment to the Seller at the same time as the General Partner submits the report described in Section 3.1(f) of the Partnership Agreement to the Partners’ Accountant for review.

(h) The Contingent Payment with respect to each Calendar Quarter shall be due to the Seller not later than five days after the Quarterly Contribution for such Calendar Quarter is due to the Partnership from the Partners under the terms of Section 3.1(f) of the Partnership Agreement. Such due date for Contingent Payments, being the date which is five days after the Quarterly Contribution Date, is herein referred to as the “Quarterly Payment Date.”

(i) If the Seller objects to the General Partner’s calculation of any Contingent Payment, the Seller shall notify the Partnership within two weeks after the Partnership has submitted the report to the Seller. If the Seller disputes the Partnership’s calculations, the Partnership shall, in good faith, consider the issues raised or in dispute and discuss such issues with the Seller and attempt to reach a mutually satisfactory agreement, taking into account as well, any issues raised by the Partners’ Accountant and if such dispute is promptly resolved, the adjusted amount agreed upon shall be the Contingent Payment due. If the dispute is not promptly resolved, the Partnership shall pay, on the Quarterly Payment Date, the amount not in dispute. Thereafter, the Seller, the General Partner and the Partners’ Accountant shall select an independent entity qualified and knowledgeable in the area to resolve the dispute and, upon resolution of the dispute, if it is determined that additional Quarterly Contributions are due from the Partners, the corresponding additional amount shall be paid to the Seller within five days of the date the additional amount of the Quarterly Contributions is due to the Partnership from the Partners.

(j) (1) If the Partnership advises the Seller in writing that a Tax Event has occurred, all payments of Contingent Payments thereafter up to an amount equal to the aggregate Maximum Tax Credit Amount At Risk shall be made into an escrow account for the benefit of the Seller (but owned by the Partnership) on terms whereby the amounts held in escrow will be released on the joint signatures of the Seller and the Partnership (which shall require the approval of a Majority in Interest of the Limited Partners, as such term is defined in the Partnership Agreement) in the following circumstances, and in the following amounts:

(i) upon a Final Determination with respect to a Partner or Partners and a Calendar Quarter or Calendar Quarters that Tax Credits are disallowed, the product of (x) the sum of (I) the amount disallowed, plus (II) any interest and penalties (including without limitation substantial understatement penalties and any penalties for underpayment of estimated taxes to the extent attributable to Tax Credits arising from the Partnership) due with respect to any such Calendar Quarters related to such Tax Credits, multiplied by (y) the applicable percentage under Section 2.01(e) hereof, shall be released from the escrow to the relevant Partner or Partners so long as the relevant Partner or Partners certifies that (A) the amount being released is in the same proportion as the amounts escrowed hereunder bear to all amounts placed into escrow following a Tax Event under this Agreement and the Sub-License Agreements, and (B) all actions necessary to cause the proportionate amounts escrowed under the Sub-License Agreements to be released have been taken or are being taken contemporaneously; and

(ii) if there is no longer an extant Tax Event as determined in accordance with the final sentence of paragraph (2) below, the amounts remaining in escrow after application of (i) above shall be released to the Seller.

(2) For purposes of this Agreement, “Tax Event” means (i) the issuance of any information document request related to Tax Credits arising from the operations of the Partnership or the Purchased Companies, or any other reasonable indication of an intention by the IRS to examine or disallow any portion of such Tax Credits, but in each case only if the IRS continues to make inquiries or persists in its examination after the IRS has been provided with a copy of the private letter ruling(s) issued to the Partnership, (ii) the Partnership’s or Seller’s becoming aware that the IRS has questioned or otherwise implicated the ability of the proprietary process licensed under the Sub-License Agreements to produce Qualified Fuels at any other synthetic fuel production project, or (iii) except with respect to matters addressed in clause (i) or (ii) above, a Majority in Interest of the Limited Partners reasonably determines, after consultation with Seller and such experts as Seller may provide, and taking into consideration the existence of the rulings received in response to the IRS Ruling Request, that it is more likely than

not that the IRS will disallow all or a portion of Tax Credits. Any Tax Event arising under this Section 2.01(j) (2) shall cease on the earlier of (A) a Final Determination, (B) when the Partnership (with the approval of a Majority in Interest of the Limited Partners or, if a Limited Partner objecting to the same delivers an opinion of nationally recognized tax counsel that it is more likely than not that the IRS will disallow Tax Credits, with the approval of all the Limited Partners) and the Seller agree that the tax issue giving rise to the Tax Event has been resolved, or (C) solely with respect to a Tax Event arising under clause (iii) above, more than one year passes without an examination of Tax Credits of the Partnership commencing or another Tax Event occurring.

(3) For purposes of this Agreement, “Final Determination” means, with respect to Tax Credits related to the Partnership,

(i) unless an adjustment is proposed with respect to any such Tax Credits, the expiration of the applicable statute of limitations for the relevant tax period and Partner;

(ii) unless an administrative appeal or a judicial proceeding is initiated by the Partnership or the affected Partner, the date ninety days after the issuance of a notice of deficiency;

(iii) unless judicial proceedings are initiated by the Partnership or the affected Partner, a final decision with respect to the proposed adjustment by an IRS appeals officer, as evidenced by the issuance of a 90-day letter, 870-AD or like notice and the expiration of the period for initiating judicial proceedings;

(iv) unless appealed by the Partnership or the affected Partner, a final decision with respect to the proposed adjustment by the United States Tax Court, Court of Federal Claims or the appropriate Federal District Court and the expiration of the period for filing an appeal of such decision;

(v) a final decision of a United States Court of Appeals with respect to the proposed adjustment, unless a petition for certiorari to the United States Supreme Court has been applied for and is pending or has been granted with respect to such decision;

(vi) denial of certiorari by, or final decision of, the United States Supreme Court; or

(vii) the settlement of a proposed adjustment as evidenced by a closing agreement.

(4) For purposes of this Agreement, “Maximum Tax Credit Amount At Risk” means the amount reasonably determined by any affected Partner to be potentially subject to disallowance by the IRS following a Tax Event, plus interest and substantial understatement penalties, which amount shall not exceed the product of (x) the sum of (I) the Tax Credits claimed by such Limited Partner with respect to the operations of the Partnership and the Project Companies for all open tax years (so long as such claims are consistent with the applicable final tax return of the Partnership as to any such tax year), it being understood that such amount is not limited to amounts directly implicated by the Tax Event (since an audit of one issue related to Tax Credits could result in a disallowance of other such credits for the same or a subsequent period, or on other grounds discovered later), plus (II) any interest and penalties payable by such affected Partner (to the extent attributable to Tax Credits arising from the Partnership), multiplied by (y) the applicable percentage under Section 2.01(e) hereof.

(5) Each of the Seller and the Partnership agrees that, promptly after obtaining knowledge thereof, it will give prompt notice of any matter that is or could become a Tax Event or that the IRS has commenced an examination of any other synthetic fuel production project utilizing the proprietary process licensed under the Sub-License Agreements, and the parties as promptly thereafter as practicable shall meet to discuss in good faith whether a Tax Event in fact exists or will likely occur and the consequences thereof.

Section 2.02. Adjustment Amounts. (a) Each year, following the publication by the IRS of the revised inflation adjustment factor and the reference price, and following the filing of the Partnership’s federal income tax return (A) the Estimated Tax Credits for each Calendar Quarter of the preceding calendar year shall be recomputed, using such revised factor and taking into account the effect of the operation of Section 29(b)(1) of the Code based on such reference price, but otherwise using the same information used to determine the Estimated Tax Credits for such periods, except as necessary to cause the aggregate Estimated Tax Credits not to exceed the Tax Credits actually reported on the Partnership’s federal income tax return; and (B) the Estimated Tax Credits for the first Calendar Quarter of the then current calendar year shall be recomputed using such revised inflation adjustment factor. The General Partner shall then determine the difference between (x) the Estimated Tax Credits for the preceding calendar year and the first Calendar Quarter of the current calendar year, as recomputed using the revised information as set forth in this Section 2.02(a) and (y) the Estimated Tax Credits as originally determined for the four Calendar Quarters in the preceding calendar year and the first Calendar Quarter of the current calendar year. The product of (I), the difference between (x) and (y) in the preceding sentence, multiplied by (II) the applicable percentage under Section 2.01 (e) hereof, is the “Annual Adjustment Amount.” If the Annual Adjustment Amount is a positive amount, it shall be

added to the amount of the Contingent Payment otherwise due on the Adjustment Date and if the Adjustment Amount is a negative number, such amount shall be used to reduce the Contingent Payment otherwise due on the Adjustment Date, or if the Adjustment Amount is negative and exceeds the amount of the Contingent Payment otherwise due on such date, the excess amount shall be successively credited against Contingent Payments as they otherwise become due thereafter.

(a) In the calendar year in which the Final Adjustment Date occurs, following the publication of the revised inflation adjustment factor and the reference price applicable to the immediately preceding calendar year and following the filing of the Partnership’s federal income tax return, the Estimated Tax Credits for each Calendar Quarter of such immediately preceding calendar year shall be recomputed, using such revised factor and taking into account the effect of the operation of Section 29(b)(1) of the Code based on such reference price, but otherwise using the same information used to determine the Estimated Tax Credits for such periods, except as necessary to cause the aggregate Estimated Tax Credits not to exceed the Tax Credits actually reported on the Partnership’s federal income tax return. The General Partner shall then determine the difference between (x) the Estimated Tax Credits for such calendar year as recomputed using the revised information as set forth in this Section 2.02(b) and (y) the Estimated Tax Credits as originally determined for the four Calendar Quarters in such calendar year. The product of (I), the difference between (x) and (y) in the preceding sentence, multiplied by (II) the applicable percentage under Section 2.01(e) hereof, is the “Final Adjustment Amount.” The Final Adjustment Amount, if positive, shall be due from the Partnership to the Seller as the final Contingent Payment on the Final Adjustment Date. If the Final Adjustment Amount is negative, the amount thereof shall be paid by the Seller to the Partnership on the Final Adjustment Date.

Section 2.03. Deferred Contingent Payments. (a) To the extent, for any Calendar Quarter, the Partnership experiences an Operating Deficit, the Partnership, with respect to the Contingent Payment due on the Quarterly Payment Date following such Calendar Quarter, shall be permitted to defer payment of the Contingent Payment due on such date up to the amount of the Operating Deficit for such Calendar Quarter. Any such amount deferred as provided in this Section 2.03 together with interest thereon is herein referred to as a “Deferred Contingent Payment.” Any amount of a Contingent Payment which is deferred shall continue as an obligation of the Partnership and shall bear interest at the rate of six percent per annum, compounded annually, until paid. If, for any Calendar Quarter, the Partnership experiences an Operating Gain and there are Deferred Contingent Payments outstanding, the Partnership shall, on or before the Quarterly Payment Date immediately following such Calendar Quarter, pay to the Seller the lesser of (i) the amount of such Operating Gain for the Calendar Quarter and (ii) the aggregate amount of unpaid Deferred Contingent Payments including

accrued and unpaid interest. Any payments made with respect to Deferred Contingent Payments shall be credited first to accrued and unpaid interest, and then to the principal amount of the unpaid Deferred Contingent Payments. All Deferred Contingent Payments not paid prior to such date shall become due and payable and shall be paid to the Seller on January 2, 2009. The Partnership agrees that, to the extent it sells assets, including, but not limited to, a sale of a Membership Interest under the terms of the Option Agreement or otherwise, the Sale or Refinancing Proceeds will be used first to pay any unpaid Deferred Contingent Payments before such amounts are used for any other purpose of the Partnership. The obligation of the Partnership to pay the Deferred Contingent Payment shall be evidenced by a promissory note substantially in the form of Exhibit B hereto.

Section 2.04. Pledge of Partnership Interest. The Partnership agrees that as a condition to the admission of each Limited Partner, it will (i) obtain from such Limited Partner a written instrument by which such Limited Partner becomes bound by the terms of the Partnership Agreement (as the same is amended or restated from time to time), (ii) obtain a pledge of such Limited Partner’s Units to secure payment of the Quarterly Contributions and a written security agreement executed by and enforceable against the Limited Partner in which the Limited Partner pledges its Units and such other security as the Partnership shall deem appropriate to secure the Limited Partners’ obligations under the Partnership Agreement, and (iii) as security, take possession of and hold until all payments due hereunder have been paid, the certificate evidencing the Units of such Limited Partner.

Section 2.05. Excluded Rights. The Seller and the Partnership acknowledge that the Purchase Price has been determined on the basis of the actual performance of the binder technology which is licensed to each of the Project Companies from Carbontec Energy Corporation (“Carbontec”), which performance is believed by the Seller to be below the levels that had been warranted by Carbontec (the “Warranty Claim”). The Seller and the Partnership agree that any claim in respect of the Warranty Claim against Carbontec constitutes an asset excluded from the purchase and sale made hereby, directly or indirectly, and the Partnership agrees to cause the Project Companies to enter into such documents as may be reasonably requested by the Seller confirming the release of any claims by the Project Companies with respect thereto.

All funds so withheld shall be maintained by the Partnership in Permitted Interim Investments (as defined in the Partnership Agreement) until released to the appropriate party (together with the earnings thereon) upon final resolution of the matter (which resolution shall require the approval of a Majority in Interest of the Limited Partners) or as directed by a court of applicable jurisdiction. In case of a breach of the representation and warranty set forth in Section 3.28 hereof (the “Capacity Warranty”), the amount of each Contingent Payment due under Section 2.01 (e) with respect to the Project as to which the breach occurred shall be reduced on a permanent basis to 40%, in each case as liquidated damages and not as a penalty. The Partnership and Seller agree that the sole remedy for any breach of the Production Warranty shall be the price reduction set forth in the immediately preceding sentence.
