The “Purchase Price” shall be equal to the Estimated Purchase Price after giving effect to any adjustment contemplated by Section 2.3. At least ten (10) Business Days prior to the Closing, Sellers shall provide to Buyer the relevant account

information and wiring instructions and Estimated Purchase Price allocation percentages for each of the Sellers for which Buyer is to remit its payment of the Estimated Purchase Price.

SECTION 2.3 Net Working Capital Adjustment. (a) At least five (5) Business Days prior to Closing, Sellers’ Representative shall prepare, in accordance with GAAP, and deliver to Buyer an unaudited statement of Estimated Net Working Capital of the Company as of the Closing Date.

(b) Within sixty (60) days after the Closing Date, Buyer shall prepare, in accordance with the definition of Net Working Capital as set forth herein, and deliver to Sellers’ Representative an unaudited statement of the Net Working Capital of the Company as of the Closing Date (the “Post-Closing Net Working Capital Statement”). From the Closing Date, Buyer shall provide Sellers’ Representative and its Representatives any information reasonably requested and shall provide them, upon reasonable notice, full access at all reasonable times to the properties, books, records and other materials of the Company and its Subsidiaries and the personnel of, and work papers prepared by or for, Buyer or the Company and its Subsidiaries, including such historical financial information relating to the Company and its Subsidiaries as Sellers’ Representative may reasonably request in connection with its review of the Post-Closing Net Working Capital Statement.

(c) Upon receipt of the Post-Closing Net Working Capital Statement, Sellers’ Representative shall have thirty (30) days (the “Review Period”) to review such Post-Closing Net Working Capital Statement. If Sellers’ Representative has accepted such Post-Closing Net Working Capital Statement in writing or has not given written notice to Buyer setting forth in reasonable detail any Sellers’ Representative’s objection to such Post-Closing Net Working Capital Statement (an “Objection Notice”) prior to the expiration of the Review Period, then such Post-Closing Net Working Capital Statement shall be final and binding upon the parties. In the event that Sellers’ Representative delivers an Objection Notice during the Review Period, (1) any undisputed portion of the amount required to be paid pursuant to Section 2.3(f) shall be paid but only if the party paying in respect of the undisputed items will pay a greater amount to the other party or no additional amount to the other party in connection with the final payment pursuant to Section 2.3(f) and (2) as to any disputed elements of the Post-Closing Net Working Capital Statement, the parties shall use their reasonable efforts to agree on any adjustments to the Post-Closing Net Working Capital Statement within twenty (20) days following the receipt by Buyer of the Objection Notice. If the parties are unable to reach an agreement as to such amount within such twenty (20) day period, then the matter shall be submitted to one of the “Big 4” accounting firms or other qualified firm as shall be mutually agreed between the parties (such accounting firm, the “Accounting Firm”), who, acting as an expert and not as an arbitrator, shall resolve the matters still in dispute, but only such matters, and shall adjust the Post-Closing Net Working Capital Statement in accordance with this Section 2.3(c) to reflect such resolution and establish the final binding Post-Closing Net Working Capital Statement. The Accounting Firm shall make such determination within thirty (30) days following the engagement of the Accounting Firm, and such determination shall be final and binding upon the parties.

(d) The scope of any dispute to be resolved by the Accounting Firm shall be limited to whether the amounts set forth on the Post-Closing Net Working Capital Statement were prepared in accordance with the definition of Net Working Capital as set forth herein, and

whether there were mathematical errors in the Post-Closing Net Working Capital Statement. In resolving a dispute relating to the Post-Closing Net Working Capital Statement or any particular item in the Post-Closing Net Working Capital Statement, the Accounting Firm may not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party, in each case as presented to the Accounting Firm.

(e) The decision of the Accounting Firm will be, for all purposes, conclusive, non-appealable, final and binding upon Buyer and Sellers. Judgment may also be entered thereon as an arbitration award pursuant to the Federal Arbitration Act, 9 U.S.C. §§1-16. The fees of the Accounting Firm shall be borne by Buyer and Sellers in the same proportion that the dollar amount of disputed items lost by a party bears to the total dollar amount in dispute resolved by the Accounting Firm. Each party will bear the fees, costs and expenses of its own accountants and all of its other expenses in connection with matters contemplated by this Section 2.3.

(f) Within two (2) Business Days after the Post-Closing Net Working Capital Statement becomes final and binding, either (i) Buyer shall pay to the Sellers an amount equal to the excess, if any, of (A) the Final Net Working Capital over (B) the Estimated Net Working Capital, or (ii) Sellers shall pay to Buyer an amount equal to the excess, if any, of (A) the Estimated Net Working Capital over (B) the Final Net Working Capital. If the Estimated Net Working Capital is equal to the Final Net Working Capital, no payments will be required by the Sellers or Buyer under this Section 2.3(f). All such payments by Buyer or Sellers will be made together with interest accruing at an annual rate of five percent (5%) beginning on the Closing Date and ending on the date of payment. All payments made pursuant to this Section 2.3 shall be made in immediately available funds by wire transfer to such bank account as Sellers or Buyer will specify, as applicable.

SECTION 2.4 Interim Capital Expenditure Payments. Between the date of this Agreement and the Closing Date, the Company, or an Affiliate of the Company on behalf of the Company or its Subsidiaries, may make interim capital expenditures in respect of the Business as identified in the Operating Budget (the “Interim Capital Expenditures”). The amount incurred as of the Closing Date by or on behalf of the Company and its Subsidiaries between the date of this Agreement and the Closing Date in respect of any Interim Capital Expenditures shall be the “ICE Payment.”

SECTION 2.5 Debt Reduction. The Base Debt is the scheduled targeted amount of all outstanding debt as of September 30, 2006 of the Business pursuant to the Credit Agreement. At the Closing, Sellers shall deliver to Buyer a certificate (the “Debt Reduction Certificate”) setting forth the difference between the Base Debt and the amount of all outstanding debt pursuant to the Credit Agreement of the Business as of the Closing (the “Closing Debt”). The difference between the Base Debt and the Closing Debt shall be the “Debt Reduction Amount.”

SECTION 2.6 Distribution of Purchase Price. The Estimated Purchase Price and any adjustment to the Estimated Purchase Price pursuant to Section 2.3 shall be distributed or

allocated to the Sellers in accordance with the percentage entitlement of each such Seller as set forth in Section 2.6 of the Sellers’ Disclosure Schedule, as may be amended from time to time.

If the Business, or any asset or portion of the Business, is damaged or destroyed by casualty loss (a “Casualty Event”) after the date hereof and prior to the Closing, and the cost of restoring such damage or destruction to the Business or any of its assets to a condition reasonably comparable to their condition prior to a Casualty Event (such costs with respect to the Business or any of its assets, the “Restoration Cost”) is greater than $2,000,000 but does not exceed $15,000,000 (as estimated by a qualified firm reasonably acceptable to Buyer and Sellers, and after giving effect to any insurance proceeds available to the Business therefor), Sellers may elect to (i) terminate this Agreement, or (ii) reduce the amount of the Purchase Price by the Restoration Cost (as estimated by a qualified firm reasonably acceptable to Buyer and Sellers, and after giving effect to any insurance proceeds available to the Business therefor), by notice to Buyer, and such Casualty Event shall not affect the Closing. If the Restoration Cost is in excess of $15,000,000 (as estimated by a qualified firm reasonably acceptable to Buyer and Sellers, and after giving effect to any insurance proceeds available to the Business therefor), Sellers may, by written notice to Buyer within 45 days after the date of such Casualty Event, elect to terminate this Agreement; provided, however, that if Sellers do not elect to terminate this Agreement as provided in this Section 7.13, then Buyer may, by written notice to Sellers’ Representative, terminate this Agreement within ten Business Days of receipt by Buyer of Sellers’ notice regarding their election. If the Restoration Cost is $2,000,000 or less then, (i) neither Buyer nor Sellers shall have the right or option to terminate this Agreement and (ii) there shall be no reduction in the amount of the Purchase Price.

SECTION 7.14 Use of Certain Names. (a) Within 30 days following Closing, Buyer shall cause the Company to cease using the words “LSP,” “LS Power”, “LS” and any word or expression similar thereto or constituting an abbreviation or extension thereof (the “Seller Marks”), including eliminating the Seller Marks from the Company and the Business and disposing of any unused stationery and literature of the Company and the Business bearing the Seller Marks, and thereafter, Buyer shall not, and shall cause the Business, the Company and its Affiliates not to, use the Seller Marks or any logos, trademarks, trade names, patents or other Intellectual Property rights belonging to the Sellers or any Affiliate thereof, and Buyer acknowledges that it, its Affiliates and the Business and the Company have no rights whatsoever to use such Intellectual Property without the written consent of the applicable Seller. Without limiting the foregoing:

(b) Within three Business Days after the Closing Date, Buyer shall cause the Company to change its name to a name that does not contain any of the Seller Marks.

(c) Within 45 days after the Closing Date, Buyer shall provide evidence to Seller, in a format that is acceptable to Seller, that Buyer has made all governmental filings required pursuant to clause (a) above and has provided notice to all applicable Governmental

Authorities and all counterparties to the Material Contracts regarding the sale of the Company and the Business to Buyer and the new addresses for notice purposes.

SECTION 7.15 Excluded Items. Notwithstanding anything in this Agreement to the contrary, Buyer and the Sellers agree that the Business shall exclude those items listed in Section 7.15 of the Sellers’ Disclosure Schedule (the “Excluded Items”), the Sellers shall retain all benefits and liabilities with respect to the Excluded Items, and the Sellers shall, prior to the Closing Date, use commercially reasonable efforts to cause the Company to distribute, transfer or assign each Excluded Item to the Sellers. Buyer acknowledges that the inability of the Sellers to have any Excluded Item distributed, transferred or assigned from the Company or the Business, as applicable, for any reason shall not delay Closing and any Excluded Item that the Sellers are unable to so distribute, transfer or assign by the Closing shall be referred to as a “Non-Transferred Excluded Item.” After the Closing Date with respect to each Non-Transferred Excluded Item, Buyer shall permit the Sellers to exclusively direct and manage the Company’s or the Business’, as applicable, participation in all negotiations, arbitrations, litigation, claims, and/or bankruptcy or other proceedings involving such Non-Transferred Excluded Item, whether existing on the Closing Date or arising thereafter. Buyer shall also permit the Sellers to settle or compromise on behalf of the Company and the Business, as applicable, any Non-Transferred Excluded Item in Sellers’ sole discretion, and shall promptly pay the Sellers any proceeds or recoveries received in connection with any Non-Transferred Excluded Item. Buyer shall, at the Sellers’ expense: (a) cause any Person under its control with knowledge of relevant facts pertaining to any Non-Transferred Excluded Item to provide assistance to the Sellers as reasonably requested by the Sellers; and (b) provide any relevant books, records, or other information of the Company or the Business to the Sellers and access to the Business, as reasonably requested by the Sellers, in connection with any Non-Transferred Excluded Item.

SECTION 7.16 Financial Statements. No later than thirty (30) Business Days after the receipt thereof, Sellers shall provide to Buyer true and correct copies of (i) the unaudited and audited financial statements of the Company dated as of December 31, 2006, and (ii) the unaudited financial statements for the Company for each quarter subsequent to December 31, 2006 and prior to the Closing Date.

SECTION 9.1 Indemnification By Sellers. Subject to the limitations and conditions set forth in this Article IX and Section 11.12 from and after the Closing, Sellers shall, severally, but not jointly, indemnify and hold harmless, to the fullest extent permitted by law, Buyer and its Subsidiaries, Affiliates and Representatives and each of their respective successors and permitted assigns (collectively, the “Buyer Indemnitees”) from and against any and all claims, demands or suits (by any Person), losses, liabilities, damages, obligations, payments, costs, Taxes, and expenses to the extent the foregoing are not covered by insurance (collectively, “Indemnifiable Losses”), which they or any of them may suffer or incur arising out of or relating to:

(a) any breach or inaccuracy of any representation or warranty made by Sellers in this Agreement; or

(b) any breach or violation, or default in performance, by Sellers of any covenant or agreement of Sellers contained in this Agreement.

SECTION 9.2 Indemnification By Buyer.

(a) Subject to the limitations and conditions set forth in this Article IX from and after the Closing, Buyer shall indemnify and hold harmless, to the fullest extent permitted by law, Sellers and their Subsidiaries, Affiliates and Representatives and each of their respective successors and permitted assigns (collectively, the “Seller Indemnitees”) from and against any and all Indemnifiable Losses which they or any of them may suffer or incur arising out of or relating to:

(i) any breach or inaccuracy of any representation or warranty made by Buyer in this Agreement;

(ii) any breach or violation, or default in performance, by Buyer of any covenant or agreement of Buyer contained in this Agreement; or

(iii) subject to Buyer’s rights under Section 9.1, any obligation, debt or other liability of the Company, its Subsidiaries, Blocker or the Business, whether direct or indirect, absolute or contingent, known or unknown, asserted or unasserted, accrued or unaccrued, liquidated or unliquidated or due or to become due, whether or not required by GAAP to be reflected in financial statements or disclosed in notes thereto, relating to any period before or after the Closing, regardless of when asserted.

(b) Effective as of the Closing, Buyer shall cause the Company to agree that the Company and its Subsidiaries shall be jointly and severally liable for all obligations of Buyer arising under this Section 9.2.

SECTION 9.3 Indemnification Procedures. In the case of any claim for indemnification brought against either Buyer Indemnitees or Seller Indemnitees pursuant to this Article IX:

(a) Any Person seeking indemnification under this Article IX (an “Indemnified Party”) shall give the party from whom indemnification is being sought (an “Indemnifying Party”) a written notice of any matter which such Indemnified Party has determined has given or would give rise to a right of indemnification under this Agreement as soon as practicable after the Indemnified Party becomes aware of any fact, condition or event that may give rise to Indemnifiable Losses for which indemnification may be sought under this Article IX. Such written notice shall state the nature and basis of any claim and the amount thereof, to the extent known, along with copies of the relevant documents evidencing such claim and the basis for indemnification sought.

(b) The liability of an Indemnifying Party under this Article IX with respect to Indemnifiable Losses arising from claims of any third party which are subject to the indemnification provided for in this Article IX (“Third Party Claims”) shall be governed by and contingent upon the following additional terms and conditions: if an Indemnified Party shall

receive a notice of any Third Party Claim, the Indemnified Party shall give the Indemnifying Party a written notice of such Third Party Claim within thirty (30) days of the receipt by the Indemnified Party of such notice; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article IX except to the extent the Indemnifying Party is materially prejudiced by such failure. The Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice; provided it gives notice of its intention to do so to the Indemnified Party within thirty (30) days of the receipt of such notice from the Indemnified Party; provided, however, that if there exists a material conflict of interest that would make it inappropriate for the same counsel to represent both the Indemnified Party and the Indemnifying Party, then the Indemnified Party shall be entitled to retain its own counsel, at the expense of the Indemnified Party; provided that the Indemnifying Party shall not be obligated to pay the reasonable fees and expenses of more than one separate counsel for all Indemnified Parties, taken together (except to the extent that local counsel is necessary or advisable for the conduct of such proceeding, in which case the Indemnifying Party shall also pay the reasonable fees and expenses of any such local counsel). If the Indemnifying Party shall not assume the defense of any Third Party Claim or litigation resulting therefrom, the Indemnified Party may defend against such claim or litigation in such manner as it may deem appropriate and may settle such claim or litigation on such terms as it may deem appropriate. In the event the Indemnifying Party exercises the right to undertake any such defense against any such Third Party Claim as provided above, the Indemnified Party shall cooperate with, and do all things reasonably practicable to assist, the Indemnifying Party in such defense and make available to the Indemnifying Party, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably requested by the Indemnifying Party.

(c) Notwithstanding anything to the contrary, the Sellers shall have the right to defend and control any environmental investigation, cleanup or other remedial or corrective action (including any related submission of reports or other documentation to any Governmental Authority) relating to any claim for indemnification under Article IX, whether or not the subject of any Third Party Claim.

SECTION 9.4 Limitations on Indemnification. (a) All of the representations and warranties of the parties contained in Article IV, Article V and Article VI and all claims and causes of action for indemnification under this Article IX with respect thereto shall survive the termination of this Agreement pursuant to Section 10.1 hereof or otherwise for twelve (12) months after the Closing Date (such period, the “General Survival Period”); provided that the representations and warranties contained in Section 4.19 (Taxes) and all claims and causes of action for indemnification under this Article IX with respect thereto shall survive such termination for a period of the applicable statute of limitation (such period, the “Tax Survival Period”, and together with the General Survival Period, each a “Survival Period”). After the expiration of the applicable Survival Period, none of the Sellers, the Buyer or any of their respective officers, directors, trustees, members, limited partners, general partners or Affiliates shall be under any liability whatsoever with respect to the applicable representations or warranties contained in this Agreement.

(b) Notwithstanding anything to the contrary in this Agreement and subject to the limitations in this Section 9.4, indemnification under Section 9.1 shall not be available unless

and until the amount of Indemnifiable Losses asserted against Sellers, under Section 9.1 equals or exceeds (i) an amount equal to $350,000 resulting from any single claim or aggregated claims arising out of the same or similar facts, events or circumstances (the “Per Claim Deductible”), and (ii) an amount equal to $3,000,000 in the aggregate (the “Deductible”). Once the Deductible has been exceeded, the Buyer Indemnitees shall be entitled to the benefit of the indemnity under Section 9.1 for any claim that exceeds the Per Claim Deductible to the extent the aggregate of all such claims is in excess of the Deductible, subject, however, to the Indemnification Cap.

(c) With respect to all claims made under this Agreement, the maximum aggregate amount of Indemnifiable Losses that may be recovered shall not exceed 10% (ten percent) of the Purchase Price (the “Indemnification Cap”).

(d) Notwithstanding any other provision of this Agreement to the contrary, the parties agree that the recovery by any Indemnified Party of any damages suffered or incurred by such Indemnified Party as a result of any breach by another party of any of its obligations under this Agreement shall be limited to the actual damages suffered or incurred by an Indemnified Party as a result of the breach by the breaching party of its obligations hereunder and in no event shall the breaching party be liable to an Indemnified Party for any indirect, consequential, special, exemplary or punitive damages (including any damages on account of lost profits or opportunities) suffered or incurred by an Indemnified Party as a result of the breach by the breaching party of any of its obligations hereunder.

(e) Notwithstanding any provision to the contrary contained in this Agreement, in the event that an Indemnifying Party can establish that an Indemnified Party had actual knowledge after due inquiry, on or prior to the Closing Date, of a breach of a representation or warranty of the Indemnifying Party upon which a claim for indemnification by the Indemnified Party is based, then the Indemnifying Party shall have no liability for any Indemnifiable Losses resulting from or arising out of such claim.

(f) The amount of any Indemnifiable Losses claimed by any Indemnified Party hereunder shall be net of any available insurance, indemnity, contribution, net Tax benefit or other payments or recoveries of a like nature with respect thereto (it being agreed that, promptly after the realization of any such reductions of Indemnifiable Losses pursuant hereto, such Indemnified Party shall reimburse the Indemnifying Party for such reduction in Indemnifiable Losses for which such Indemnified Party was indemnified prior to the realization of such reductions of Indemnifiable Losses).

(g) If an Indemnified Party recovers Indemnifiable Losses from an Indemnifying Party under this Article IX, the Indemnifying Party shall be subrogated, to the extent of such recovery, to the Indemnified Party’s rights against any third party, with respect to such recovered Indemnifiable Losses subject to the subrogation rights of any insurer providing insurance coverage under one of the Indemnified Party’s policies and except to the extent that the grant of subrogation rights to the Indemnifying Party is prohibited by the terms of the applicable insurance policy.

(h) The amount of any Indemnifiable Losses claimed by any Buyer Indemnified Party hereunder shall be reduced to the extent that Buyer shall have received the

benefit of an adjustment pursuant to Section 2.3 due to the fact that the item that is the subject of the indemnification claim was specifically taken into account in the final Post-Closing Net Working Capital Statement.

(i) Notwithstanding anything to the contrary in this Agreement, in no case shall Sellers owe any indemnification under Section 9.1 with respect to any breach or inaccuracy of any of the representations or warranties contained in Section 4.12, (i) except to the extent any Indemnifiable Losses were incurred to comply with applicable Environmental Law as of the Closing Date; (ii) to the extent any Release of Hazardous Materials, non-compliance with Environmental Law or other condition forming the basis of any Indemnifiable Losses was contributed to or exacerbated by the Buyer Indemnitees; or (iii) to the extent any Indemnifiable Losses result from or arise out of (y) any change subsequent to the Closing Date in the use of the Business or the plants or other facilities or properties constituting the Business or (z) any voluntary investigation, reporting, cleanup or other voluntary remedial activity by any Buyer Indemnitee.

SECTION 9.5 Mitigation; Cooperation. The parties shall cooperate with, and do all things reasonably practicable to assist, each other to mitigate or resolve any claims or Indemnifiable Losses. The Indemnified Party shall reasonably cooperate and assist the Indemnifying Party in determining the validity of any claim for indemnity by the Indemnified Party and in otherwise resolving such matters. Such assistance and cooperation shall include providing reasonable access to and copies of information, records and documents relating to such matters.

SECTION 9.6 Exclusivity of Indemnification Remedy. Any claim or cause of action (whether such claim sounds in tort, contract or otherwise and including statutory rights and remedies) based upon, relating to or arising out of this Agreement must be brought by such party in accordance with the provisions and applicable limitations of this Article IX, which shall constitute the sole and exclusive remedy of all parties and their Affiliates, successors and assignees for any such claim or cause of action.

SECTION 9.7 Characterization of Indemnification Payments. The parties agree to treat for Tax purposes any indemnification payment made under this Agreement as an adjustment to the Purchase Price.

SECTION 11.5 Governing Law; Consent to Jurisdiction and Service of Process; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware. All Actions arising out of or relating to this Agreement shall be heard and determined in any state or Federal court sitting in Delaware, and the parties hereby irrevocably submit to the exclusive jurisdiction of such courts in any such Action and irrevocably waive the defense of an inconvenient forum to the maintenance of any such Action.

TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 11.6 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

SECTION 11.7 Interpretation. The article and section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and shall not in any way affect the meaning or interpretation of this Agreement.

SECTION 11.8 Third Party Beneficiaries. This Agreement is solely for the benefit of the parties and their respective successors and permitted assigns, and nothing in this Agreement, expressed or implied, is intended to confer on any Person other than the parties or their respective successors and assigns any rights, remedies, obligations or liabilities under or because of this Agreement.

SECTION 11.9 Specific Performance. The parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms of this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or in equity.

SECTION 11.11 Severability. The invalidity or unenforceability of any term or provision of this Agreement in any situation or jurisdiction shall not affect the validity or enforceability of the other terms or provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction and the remaining terms and provisions shall remain in full force and effect, unless doing so would result in an interpretation of this Agreement which is manifestly unjust.
