(A) the principal amount of any such debt for borrowed money shall not exceed the sum of the aggregate outstanding principal amount, plus all accrued but unpaid interest and other amounts payable in respect of the JPM Debt, plus any fees or expenses incurred in connection with such refinancing;

(B) the outstanding principal amount of, together with all accrued but unpaid interest on, such debt for borrowed money must be prepayable at Closing at the option of CEH; and

(C) any such Equity Securities shall, at the Effective Time, by their terms and pursuant to Section 3.01(a), be cancelled and automatically converted solely into a portion of the CEH Group Merger Consideration in accordance with Section 3.01(a), Section 3.01(f) and Exhibit F, without any modification or amendment to this Agreement.

(ii) CEH agrees that it will not enter into any definitive agreement on or prior to September 15, 2008 with respect to any incurrence of debt for borrowed money or issuance of Equity Securities in exchange for, or the proceeds of which are to be used to refinance any principal, interest or other amount payable in respect of the JPM Debt unless CEH shall have obtained the prior written consent of GSCAC, which consent shall not to be unreasonably withheld, conditioned or delayed.

(iii) If CEH or any Project Company proposes to enter into any definitive agreement at any time after September 15, 2008 with respect to any incurrence of debt for borrowed money or issuance of Equity Securities in exchange for, of the proceeds of which are to be used to refinance, any principal, interest or other amount payable in

- 54 -

respect of the JPM Debt, then CEH agrees to deliver to GSCAC copies of any final termsheet and the proposed definitive agreements and such notice shall specify that it is being delivered pursuant to this Section 6.05(a)(iii). Upon receipt of such notice, GSCAC shall have the right to terminate this Agreement in accordance with Article IX by delivering written notice of such termination to CEH on or prior to the fifth Business Day following GSCAC’s receipt of such notice relating to such proposal. If GSCAC does not terminate this Agreement in accordance with the immediately preceding sentence on or prior to such fifth Business Day, then GSCAC shall be deemed to have consented to the incurrence of such debt or issuance of such Equity Securities and the execution and delivery by CEH and/or any Project Company of such definitive documents and this Agreement shall be deemed to be automatically amended and modified to permit such requested action without any requirement for written consent thereto or any other action by any Party.

(iv) If any of the material final terms or conditions of any such debt for borrowed money or issuance of such Equity Securities differs in any material respects from the provisions of the proposal delivered pursuant to Section 6.03(a)(iii), CEH shall again provide written notice pursuant to Section 6.03(a)(iii) and GSCAC shall again have a right to terminate this agreement pursuant to and in accordance with Section 6.03(a)(iii).

Section 6.06 Insurance. CEH shall use commercially reasonable efforts to maintain or cause to be maintained in full force and effect the insurance policies described on Schedule 6.06 of the CEH Disclosure Schedule until the Closing.

Section 6.07 Casualty and Condemnation.

(a) If during the Interim Period any of the Purchased Assets are damaged or destroyed by any casualty event or are taken by any condemnation event, then CEH shall prepare (or if GSCAC objects to CEH’s estimate within 5 Business Days after receipt of such estimate, CEH shall request that a qualified independent firm reasonably acceptable to CEH and GSCAC prepare) within 15 to 45 days following such event (as such number of days is requested by CEH) (i) in the case of such a casualty event, the sum of (A) the cost of restoring the Purchased Assets damaged or destroyed by such event to a condition reasonably comparable to their condition immediately prior to such casualty event plus (B) the amount of any lost profits with respect to such Purchased Assets reasonably expected to accrue after Closing as a result of such casualty event, or (ii) in the case of such a condemnation event, the condemnation value therefor, in the case of clauses (i) and (ii) net of and after giving effect to (without duplication) (1) any insurance, condemnation award or other third party proceeds reasonably expected to be available to the applicable Project Company for such event, (2) any amounts expended by the applicable Project Company prior to Closing to restore damage caused by such casualty event and (3) adjustments relating to such casualty event or condemnation event that result in a reduction to

- 55 -

the Designated Cash Account Balances that would otherwise exist at Closing (as applicable, such estimate being a “Casualty Estimate”). Any Casualty Estimate shall be prepared based on the best reasonably available information as of the date of such Casualty Estimate and if the Closing is expected to occur prior to the end of the 15 to 45 day period referenced above (as such number of days is requested by CEH pursuant to the first sentence of this Section), then the determination of such Casualty Estimate shall not delay, impair or otherwise affect the Closing except that the Closing Date shall be extended, if necessary, to the earlier of (x) third Business Day after such Casualty Estimate is made and (y) the 5th day following the 15 to 45 day period (as requested by CEH pursuant to the first sentence of this Section 6.07) following such casualty event or condemnation event.

(b) If the Casualty Estimate with respect to all such casualty or condemnation events is greater than $3,000,000 but does not exceed $25,000,000, then the LP Enterprise Value (in the case of a Casualty Estimate with respect to the La Paloma Project) or the BV Enterprise Value (in the case of a Casualty Estimate with respect to the Batesville Project) set forth on Exhibit F shall be reduced by an amount equal to such Casualty Estimate minus $3,000,000, in which case CEH and its Affiliates shall have no further liability hereunder due to such casualty or condemnation event and such casualty or condemnation event shall not otherwise affect the Closing.

(c) If the Casualty Estimate with respect to all such casualty or condemnation events is greater than $25,000,000, GSCAC may, by written notice to CEH before the expected Closing Date, elect to (i) reduce the LP Enterprise Value (in the case of a Casualty Estimate with respect to the La Paloma Project) or the BV Enterprise Value (in the case of a Casualty Estimate with respect to the Batesville Project) set forth on Exhibit F by an amount equal to such Casualty Estimate minus $3,000,000, in which case CEH and its Affiliates shall have no further liability hereunder due to such casualty or condemnation event and such casualty or condemnation event shall not otherwise affect the Closing, or (ii) terminate this Agreement; provided, however, that if GSCAC does not elect to terminate this Agreement as provided in this sentence, then CEH may, by written notice to GSCAC on or before the expected Closing Date (or, if later, 50 days after the date of such casualty or condemnation event but prior to the Closing Date), terminate this Agreement in accordance with Article IX.

(d) If the Casualty Estimate with respect to all such casualty or condemnation events is $3,000,000 or less, (i) neither GSCAC nor CEH shall have the right or option to terminate this Agreement as a result of such casualty or condemnation event, (ii) there shall be no reduction in the amount of the LP Enterprise Value or the BV Enterprise Value set forth on Exhibit F with respect to such casualty or condemnation event; and (iii) such casualty or condemnation event shall not delay, impair or otherwise affect the Closing; and (iv) there shall be no liability for GSCAC, CEH or any of their respective Affiliates hereunder due to such casualty or condemnation event.

Section 6.08 Tax Matters.

(a) Except as provided in this Section 6.08(a), GSCAC shall prepare and file (or cause to be prepared and filed) all Tax returns relating to any Project Company that are required to be filed after the Closing Date. With respect to any income Tax returns covering a taxable

- 56 -

period ending on or before the Closing Date that are required to be filed after the Closing Date with respect to any Project Company (other than Batesville Investor I, Batesville Investor II, LSP Energy, Inc. and LSP Batesville Funding Corporation) CEH shall cause such Tax returns to be prepared and filed with the appropriate Taxing Authority. GSCAC agrees to cause the income, gain, loss and deduction of CEP Batesville Acquisition for the taxable year that includes the Closing Date to be allocated between CEH and GSCAC under Section 706 of the Code using a closing of the books on the Closing Date.

(b) After the Closing, GSCAC shall grant or cause the Project Companies to grant to CEH (or its respective designees) access at all reasonable times to all of the information, books and records relating to the Project Companies within the possession of GSCAC (including workpapers and correspondence with Taxing Authorities) and to the employees of the Project Companies, and shall afford CEH (or its designees) the right (at CEH’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit CEH (or its designee) to prepare Tax returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund claims and to conduct negotiations with Taxing Authorities. After the Closing, CEH and GSCAC will preserve (and GSCAC will cause all Project Companies to preserve) all information, records or documents in their respective possessions relating to liabilities for Taxes of the Project Companies until six months after the expiration of any applicable statute of limitations (including extensions thereof) with respect to the assessment of such Taxes; provided, that no Party shall dispose of any of the foregoing items without first offering such items to the other Parties. GSCAC agrees to make the election referred to in Section 754 of the Code with respect to Holdco Sub and any entities taxable as partnerships for federal income tax purposes in which it has a direct or indirect interest. The Parties understand that the transactions contemplated by this Agreement will give rise to special allocations under Section 704(c) of the Code (or to analogous “reverse 704(c) allocations”) and agree that, with respect to such allocations, Holdco Sub will utilize “remedial method” for allocations with respect to contributed property subject to Code Section 197 and the “traditional method with curative allocations” for all other items of property, pursuant to Section 1.704-3 of the Treasury Regulations and will apply consistent principles with respect to any assets held by any lower tier partnerships.

(c) GSCAC, CEH and Holdco Sub intend that for federal income tax purposes the Merger will be treated as follows: (i) the formation of Holdco Sub as a new partnership, (ii) for GSCAC, a contribution to Holdco Sub of the assets described in Section 2.07(b) in exchange for Holdco Class A Units, (iii) for the holders of CEH Units other than the Specified CEH E-Units, a contribution of the CEH Units described in Section 3.01(a) to Holdco Sub in exchange for the CEH Group Merger Consideration, (iv) for the holders of the Specified CEH E-Units, a transfer of such CEH Units to Holdco Sub in exchange for the Specified CEH E-Unit Consideration, and (v) for Holdco Sub, (A) the receipt of the assets described in Section 2.07(b) as a contribution from GSCAC in exchange for Holdco Class A Units, and (B) the acquisition of the assets and liabilities of CEH in exchange for the CEH Group Merger Consideration and the Specified CEH E-Unit Consideration. GSCAC, CEH and Holdco Sub each agree to file all Tax Returns consistent with this Section 6.08(c) for all Tax purposes unless otherwise required by Law.

GSCAC will notify CEH promptly of any request by the SEC or its staff or any other governmental officials for amendments or supplements to any Other Filing or for other additional information and will supply CEH with copies of all written correspondence between GSCAC or any of its representatives, on the one hand, and such government officials, on the other hand, with respect to any Other Filing. GSCAC agrees that the Proxy Statement and the Other Filings will comply in all material respects with all applicable Laws and the rules and regulations promulgated thereunder.

The Proxy Statement will be sent to the GSCAC Stockholders for the purpose of soliciting proxies from GSCAC Stockholders to vote in favor of (i) the Initial Business Combination contemplated by this Agreement, (ii) the issuance and sale of the GSCAC Class B Common Stock and the GSCAC Class A Common Stock (including GSCAC Class A Common Stock into which the Holdco Class B Common Units may be exchanged); (iii) the adoption of the GSCAC Plan; and (iv) the amendments to the Certificate of Incorporation of GSCAC as required so that the Certification of Incorporation of GSCAC can be amended and restated in substantially the form set forth on Exhibit D (the matters described in clauses (i) through (iv), the “Voting Matters”).

(b) As soon as practicable after mailing the Proxy Statement to the GSCAC Stockholders, GSCAC shall call, convene and hold a meeting of the GSCAC Stockholders (the “GSCAC Stockholders’ Meeting”) and solicit proxies from such holders to vote in favor of the approval of the Transaction and the other Voting Matters. GSCAC’s obligation to call, convene and hold such meeting shall not be affected by any Change in Recommendation by the GSCAC Board unless this Agreement is terminated by CEH pursuant to Article IX. Notwithstanding anything to the contrary contained in this Agreement, GSCAC shall adjourn or postpone the GSCAC Stockholders’ Meeting to the extent necessary to ensure that any required supplement or amendment to the Proxy Statement is provided to the GSCAC Stockholders or, if as of the time for which the GSCAC Stockholders’ Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of GSCAC Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct business at such meeting.

(c) CEH agrees to use reasonable best efforts to provide GSCAC with all information concerning the Project Companies as is reasonably requested by GSCAC for the information concerning the Project Companies in the Proxy Statement to comply with all applicable provisions of and rules under the Exchange Act or requirements of AMEX in the preparation, filing and distribution of the Proxy Statement, the solicitation of proxies thereunder, and the calling and holding of the GSCAC Stockholders’ Meeting or as may be reasonably required to respond to any comment of the SEC. GSCAC shall ensure that the Proxy Statement does not, as of the date on which it is distributed to the GSCAC Stockholders, and as of the date of the GSCAC Stockholders’ Meeting, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading (provided that GSCAC shall not be responsible for ensuring that any information furnished by CEH in writing for inclusion in the Proxy Statement does not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading). With respect to the information furnished by CEH in writing with respect to the Project Companies for inclusion in the Proxy Statement, CEH shall ensure that the Proxy Statement does not, as of the date on which it is distributed to the GSCAC Stockholders, and as of the date of the GSCAC Stockholders’ Meeting, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading (provided that CEH shall not be responsible for ensuring that any information furnished by a GSCAC Party in writing for inclusion in the Proxy Statement does not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading).

(d) Subject to Section 6.13 but without limiting Section 6.09(b), the GSCAC Board shall recommend that the GSCAC Stockholders vote in favor of approval of the Transactions and the other Voting Matters, and GSCAC, acting through its board of directors, shall include in the Proxy Statement such recommendation, and shall otherwise use all reasonable best efforts to obtain the Requisite Shareholder Approval.

(e) CEH agrees to use reasonable best efforts to obtain a “comfort letter” in form and substance reasonably satisfactory to GSCAC from UHY ▇▇▇▇, Frankfort ▇▇▇▇▇ & ▇▇▇▇,

Section 6.11 Public Disclosure. The Parties agree that no public release or announcement concerning this Agreement or the Transactions shall be issued by any Party or any of their respective Affiliates or any of their respective Representatives without the prior consent of GSCAC and CEH, unless such Party determines that it is required by any Laws or by the rules and regulations of, or pursuant to any agreement with, a stock exchange or trading system. If any Party determines that it is required by any Laws or by the rules and regulations of, or pursuant to any agreement with, a stock exchange or trading system, to make this Agreement and the terms of the Transaction public or otherwise issue a press release or make public disclosure with respect thereto, it shall, to the extent permitted by Law, at a reasonable time before making any public disclosure, consult with the other Party regarding such disclosure and give the other Party reasonable time to comment on such release or announcement in advance of such issuance.

Notwithstanding the foregoing or anything else in this Agreement to the contrary, at any time prior to obtaining the Requisite Stockholder Approval and subject to compliance with this Section, the GSCAC Board may make a Change in Recommendation if GSCAC receives an unsolicited Acquisition Proposal that the GSCAC Board determines in good faith, after taking into account relevant legal, financial, regulatory, transaction timing and certainty of consummation and other aspects of such proposal would, if consummated in accordance with its terms, constitute an Acquisition Proposal that the Board of Directors of the Company determines in good faith will be more favorable and provide greater value to GSCAC’s stockholders than the Transactions (taking into account any proposal by CEH to amend the terms of the this Agreement), or if the GSCAC Board otherwise determines in good faith (after consultation with outside counsel) that the failure to make a Change in Recommendation would be inconsistent with its fiduciary duties under applicable Law.

(b) With respect to any Permitted CEH Strategic Discussions, CEH shall not, and shall not permit any other Project Company or any of their respective Representatives to, enter into any Contract or otherwise make any commitments in connection with any such discussions (other than a confidentiality agreement on customary terms), except with the consent of GSCAC, and CEH agrees to keep GSCAC reasonably informed on a current basis of the status and details and any material developments in any such discussions.

Notwithstanding anything in this Agreement to the contrary during the Interim Period GSCAC agrees to deliver to Fulcrum a binding written offer to be held open for at least 20 Business Days to exchange all of Fulcrum’s membership interests in CEP Batesville Holding for the Fulcrum Exchange Consideration on terms and conditions substantially similar to those set forth in Exhibit O (excluding any such terms and conditions relating to the La Paloma LLC Agreement). Each Party shall promptly inform the other of any communication from or to, and any proposed understanding or agreement with, Fulcrum with respect to such offer and/or exchange. The Parties acknowledge and agree that, notwithstanding anything to the contrary in this Agreement, none of (A) the acceptance or rejection by Fulcrum of such offer described above, (B) any matter in dispute regarding the price or exchange consideration with respect to such offer, (C) any negotiations, documentation or approvals to purchase Fulcrum’s membership interests in CEP Batesville Holding, or (D) the consummation or failure to consummate for any reason the exchange contemplated by this Section shall in any case constitute a failure of a condition to be satisfied under Article VII or impair, delay or otherwise affect the Closing of the transactions contemplated by this Agreement.

Section 6.20 Amendments of CEH Disclosure Schedule. During the Interim Period, CEH may at its option supplement, amend or update the CEH Disclosure Schedules as necessary to complete, supplement or correct any information in such Schedules or in any representation or warranty in Article IV by delivering to GSCAC a copy of such amendment, supplement or update together with a notice that such document is being delivered pursuant to this Section 6.20.

CEH acknowledges that monies in the Trust Account may be disbursed only (1) to GSCAC in limited amounts from time to time (and in no event more than $2,400,000 in total) in order to permit GSCAC to pay its operating expenses; (2) if the Company completes an Initial Business Combination (as defined in its Charter Documents), to certain dissenting public stockholders, to the underwriters in the amount of underwriting discounts and commissions they earned in the IPO but whose payment they have deferred, and then to GSCAC; and (3) if GSCAC fails to complete an Initial Business Combination within the allotted time period and liquidates subject to the terms of the Trust Agreement, to GSCAC in limited amounts to permit GSCAC to pay the costs and expenses of its liquidation and dissolution and then to GSCAC’s public stockholders.

(b) For and in consideration of this Agreement, CEH hereby agrees to waive any Claim of any kind that CEH has or may have in the future in or to any monies in the Trust Account and not to seek recourse against the Trust Account or any funds distributed therefrom (except amounts released to GSCAC as described in clause (1) of the preceding paragraph or amounts distributed to GSCAC (excluding amounts described in clause (2) of the preceding paragraph) after the consummation of its Initial Business Combination) as a result of, or arising out of, any
