(c) Within ten (10) Business Days after the date on which the Buyer's written notice of dispute is required to be delivered in accordance with Section 3.2(b), (i) the Buyer shall pay to the Seller an amount equal to the sum of all undisputed portions of the Adjustment Amount reflected in the Seller's Adjustment Statement if the sum of such undisputed portions is a positive number, or (ii) the Seller shall pay to the Buyer an amount equal to the amount by which the sum of all undisputed portions of the Adjustment Amount reflected in the Seller's Adjustment Statement is less than zero, if the sum of such undisputed portions is less than zero. If there is a dispute with respect to any amount on the Adjustment Statement or the Adjustment Amount, within five (5) Business Days after the final determination of all such disputed amounts in accordance with Section 3.2(b), the Buyer shall pay to the Seller an amount equal to the

disputed portion of the Adjustment Amount as finally determined to be payable with respect to the Adjustment Statement in accordance with Section 3.2(b) if such amount is a positive number; provided, however, that if such finally determined portion is less than zero, then the Seller shall pay to the Buyer the amount by which such amount is less than zero. All payments made pursuant to this Section 3.2(c) shall be paid together with interest thereon for the period commencing on the Closing Date through the date of payment, calculated at the prime rate of Citibank, N.A. in effect on the Closing Date, in cash by wire transfer of immediately available funds.

Section 3.3 Allocation of Purchase Price.

(a) The Buyer shall allocate the Estimated Purchase Price, together with liabilities that are deemed to be assumed for U.S. federal income tax purposes (the "Allocation"), among the assets owned by Ravenswood and the Shares in accordance with section 1060 of the Code and the Treasury Regulations thereunder (or any similar provision of local or state Tax Law) and shall submit the proposed Allocation to the Seller not later than thirty (30) days after the Closing Date. If there is any adjustment to the Purchase Price, the Buyer shall modify the Allocation by allocating such adjustment in accordance with section 1060 of the Code and the Treasury Regulations thereunder (or any similar provision of local or state Tax Law) and shall submit the new proposed Allocation to the Seller within sixty (60) days after such adjustment. If, within twenty (20) days after the receipt of the proposed Allocation, the Seller notifies the Buyer in writing that the Seller disagrees with the proposed Allocation, then the Buyer and the Seller shall attempt in good faith to resolve their disagreement within thirty (30) days following the Seller's notification to the Buyer of such disagreement. If the Seller does not so notify the Buyer within twenty (20) days after receipt of the proposed Allocation, or upon resolution of the dispute by the Seller and the Buyer, the proposed Allocation shall become the final Allocation. In the event the Buyer determines that it would like to make an election under section 338(h)(10), the Seller and the Buyer shall, at the same time and subject to the same constraints set forth above pursuant to the allocation under section 1060 of the Code, allocate the "adjusted deemed sale price" among the assets of Services in accordance with section 338 of the Code and the Treasury Regulations promulgated thereunder. The term "adjusted deemed sale price" shall be based on the allocation of the Purchase Price to the Shares as set forth above and shall otherwise be determined in accordance with section 338 of the Code and the Treasury Regulations promulgated thereunder.

(b) If the Buyer and the Seller are unable to resolve their disagreement within the thirty (30) days following any such notification by the Buyer, the dispute shall be submitted to a nationally recognized independent accounting firm or law firm chosen jointly by the Buyer and the Seller, for resolution within thirty (30) days after such submission. Both the Buyer and the Seller agree to accept the independent accounting firm's or law firm's, as the case may be, determination of the final Allocation. Any fees, costs and expenses of the independent accounting firm or law firm, as the case may be, with respect to such dispute shall be borne equally by the Buyer and the Seller (unless otherwise determined by the independent accounting firm or law firm).

(c) Each of the Buyer and the Seller agrees to file Internal Revenue Service Form 8594 and Internal Revenue Service Form 8883, and all federal, state, local and foreign Tax Returns, in accordance with the final Allocation. Unless the parties otherwise agree, each of the Buyer and the Seller shall report the transactions contemplated by this Agreement for all Tax purposes in a manner consistent with the final Allocation determined pursuant to this Section 3.3. Each of the Buyer and the Seller agrees to provide the other within a reasonable timeframe with any other information required to complete Form 8594 and Form 8883 (or any similar state, local, or foreign Tax form). Each of the Buyer and the Seller shall notify and provide the other with reasonable assistance in the event of an examination, audit or other proceeding regarding the final Allocation.

(b) Except as otherwise provided in Section 7.7(a) above, the Seller shall prepare and file or cause to be prepared and filed when due all Tax Returns that are required to be filed by or with respect to the Companies for taxable years or periods ending on or before the Closing Date, and the Seller shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. The Buyer shall prepare and file or cause to be prepared and filed when due all Tax Returns that are required to be filed by or with respect to the Companies for taxable years or periods ending after the Closing Date, and the Buyer shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. Upon the written request of the Buyer setting forth in

To the extent permitted or required by applicable Law or administrative practice, the taxable year of each of the Companies which includes the Closing Date shall be treated as closing on (and including) the Closing Date. For purposes of apportioning between the Seller and the Buyer the Taxes of the Companies or with respect to the assets of the Company for a Straddle Period (which is not treated under the immediately preceding sentence as closing on the Closing Date), such liability shall be apportioned between the period deemed to end at the close of the Closing Date, and the period deemed to begin at the beginning of the day following the Closing Date on the basis of an interim closing of the books, except that Taxes (such as real or personal property Taxes) imposed on a periodic basis shall be allocated on a daily basis.

(c) Each of the Buyer and the Seller shall provide the other with such assistance as may reasonably be requested (including access to the assets, properties, personnel and records of either of the Companies) by the other party in connection with the preparation of any Tax Return, any audit or other examination by any taxing authority, or any judicial or administrative proceedings relating to liability for Taxes with respect to the Companies and each shall retain and provide the requesting party with any records or information which may be relevant to such return, audit or examination, proceedings or determination. Any information obtained pursuant to this Section 7.7 or pursuant to any other Section hereof providing for the sharing of information or review of any Tax Return or other schedule relating to Taxes with respect to the Companies shall be kept confidential by the parties hereto except to the extent that a party is legally compelled to disclose such information. After the Closing Date, in the case of any Claim with respect to Taxes for which the Seller is or may be liable or entitled to a refund pursuant to this Agreement, the Buyer shall promptly inform the Seller of such Claim, and shall afford the Seller, at the Seller's expense, the opportunity to control the conduct of such Claims and, if there is a reasonable basis therefor, initiate any claim for refund, file any amended return or take any other action which the Seller deems appropriate with respect to such Taxes. The Buyer shall execute or cause to be executed powers of attorney or other documents necessary to enable the Seller to take all actions desired by the Seller with respect to such Claim to the extent such Claim may affect the amount of Taxes for which the Seller is liable or entitled to a refund pursuant to this Agreement. Any Claim with respect to Taxes for a period which includes but does not end on the Closing Date shall be controlled by the Buyer. Notwithstanding any provision of this Section 7.7(c) to the contrary, the Seller shall not settle any Claim, initiate any claim for refund or file any amended Tax Return without the prior written consent of the Buyer, which consent shall not be unreasonably withheld, conditioned, or delayed, if, as result of such Claim, claim for refund or amended Tax Return, the Taxes payable by the Buyer or either Company for a taxable period for which the Seller is not obligated to indemnify the Buyer or either Company would likely be materially increased. Notwithstanding any provision of this Section 7.7(c) to the contrary, the Buyer shall not settle any Claim, initiate any claim for refund or file any amended return without the prior written consent of the Seller, which consent shall not be unreasonably withheld if, as a result of such Claim, claim for refund or amended Tax Return, the Taxes for which the Seller is obligated to indemnify the Buyer or the company pursuant to Section 7.7 would likely be materially increased.

(d) Notwithstanding any other provision of this Agreement, from and after the Closing Date, the Seller shall protect, defend, indemnify and hold harmless the Buyer and its Affiliates from any and all Taxes (including any obligation to contribute to the payment of any Taxes determined on a consolidated, combined, or unitary basis with respect to a group of corporations that includes or included the Companies) which are (i) imposed on the Seller or any member of the consolidated, unitary or combined group which includes or included either Company for any period that ends on or before the Closing Date, that the Buyer or either Company pays, otherwise satisfies in whole or in part, or results in Encumbrances on any of the Buyer's or either Company's assets; or (ii) imposed on either Company in respect of its income, business, property or operations or for which it may otherwise be liable (A) for any taxable period of such Company or portion thereof ending prior to the Closing Date, (B) resulting by reason of the several liability of such Company pursuant to Treas. Reg. Section 1.1502-6 or any analogous state, local or foreign law or regulation by reason of its having been a member of any consolidated, combined or unitary group on or prior to the Closing Date, or (C) resulting from its ceasing to be a member of any consolidated, combined or unitary group as of the Closing Date. The Seller shall have no liability under this Section 7.7(d) as to matters resulting from or arising out of (x) activities of the Buyer or its Affiliates, (y) conduct of the Buyer or its Affiliates that conflict with this Agreement or (z) failures by the Buyer or its Affiliates to make filings or take other actions required to be taken by the Buyer or its Affiliates under this Agreement (in each case, including each Company as an Affiliate of the Buyer from and after the Closing Date and in each case, other than matters resulting from or arising out of actions taken or failed to be taken at the direction of the Seller or its Affiliates).

(e) Any Tax refund (including any interest in respect thereof) received by the Buyer or any of the Companies, and any amounts credited against Tax to which the Buyer or any of the Companies becomes entitled (including by way of any amended Tax Returns or any carryback filing), that relate to any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period deemed to end on and include the Closing Date, shall be for the account of the Seller, and the Buyer shall pay over to the Seller any such refund or the amount of any such credit within five days after receipt of such credit or entitlement thereto. The Buyer shall pay the Seller interest at the rate prescribed under section 6621(a)(1) of the Code, compounded daily, on any amount not paid when due under this Section 7.7(e).

(f) Where it is necessary for purposes of this Section 7.7 to apportion between the Seller and the Buyer the Taxes of the Companies for a Straddle Period, such liability shall be apportioned between the period deemed to end at the close of the Closing Date, and the period deemed to begin at the beginning of the day following the Closing Date on a daily basis.

(g) At the option of the Buyer, each of the Seller and the Buyer shall cause an authorized person to make a valid and timely joint election under section 338(h)(10) of the Code and a similar election under any applicable state, local or foreign income tax Law for Services (the "Section 338(h)(10) Elections"). To facilitate such election, the Seller shall deliver to the Buyer on the Closing Date an Internal Revenue Service Form 8023 and any similar form under

applicable state, local or foreign income tax Law (collectively, the "Forms") properly signed and authorized by the Seller with respect to the Section 338(h)(10) Election, which Forms shall have been duly executed by an authorized person. The Seller and the Buyer shall cooperate in the preparation of any information to be included in the Forms or attachments thereto. The Buyer shall timely file the Forms with the relevant taxing authorities. The Buyer shall duly and timely file the Forms as prescribed by Treasury Regulation §1.338(h)(10)-1 or the corresponding provisions of applicable state, local or foreign income tax Law, and deliver evidence of such filings to the Seller.

Prior to the Closing, for all purposes of this Agreement including for purposes of determining whether the conditions set forth in Article VIII have been fulfilled, the Seller Disclosure Schedules shall be deemed to include only that information contained therein on the date of this Agreement and shall be deemed to exclude all information contained in any such correction, supplement or amendment thereto. After the Closing, for all purposes of this Agreement, including Article IX (except with respect to any matter disclosed as a result of a breach by the Seller or Energy of any of their respective covenants contained herein) any information with respect to any matter not existing prior to the date of this Agreement disclosed pursuant to any such supplement or amendment shall be deemed to be included in the Seller Disclosure Schedules. The Seller and Energy acknowledge and agree that the Buyer requires a reasonable amount of time to review any corrections, supplements and amendments to the Seller Disclosure Schedules and, accordingly, shall provide the Buyer with any corrections, supplements and amendments to the Seller Disclosure Schedules at least three (3) Business Days prior to the Closing (unless a lesser time is agreed to by the Buyer).

Any management employee of the Companies who, as of the Closing Date, is on short term or long term disability (the names of which Persons will be provided to the Buyer on the Closing Date) shall be transferred to the employment of the Seller or one of its Affiliates (other than the Companies) immediately prior to the Closing Date; provided, however, that if such Person returns to active employment status within eighteen (18) months after the Closing Date, the Buyer or one of its Affiliates shall then offer employment to such Person in accordance with this Section 7.9(b)(i).

(ii) Continuing Corporate Employees. Except to the extent previously provided in the Electronic Data Room, the Seller shall, within five (5) Business Days after the date hereof, provide the Buyer with information about the employees listed on Section 7.9(b)(ii) of the Seller Disclosure Schedules (each, a "Corporate Employee") including; job title, the market reference point of the position, compensation data (including base salary, current short term and long term incentive targets and actual base pay and bonus for the last two (2) completed years), work location, date of hire, recognized service date, and any other information reasonably requested by the Buyer that is necessary for payroll and administration of each employee.

Notwithstanding the foregoing, the Buyer shall be required to offer employment pursuant to this Section 7.9(b)(ii) in a manner that complies in all respects with applicable Law, including Laws governing employment discrimination, wages and hours, employee classifications, immigration and work conditions.

(d) Service Credit and Vacation Accrual for Continuing Employees. Each Continuing Employee shall be given credit for all service prior to the Closing Date, to the same extent as such service was credited under the applicable Benefit Plan, under all Benefit Plans of the Buyer for purposes of eligibility, vesting, and determination of level of benefits but not for purposes of benefit accrual; provided, however, that each Continuing Union Employee and Continuing Management Employee shall also receive such credit for benefit accrual purposes under the applicable Buyer Pension Plan to the extent assets and liabilities with respect to such service are transferred from a Seller Pension Plan to such Buyer Pension Plan. Notwithstanding the foregoing, such service shall not be recognized to the extent that it results in the duplication of benefits. In addition, effective as of the Closing Date, the Buyer will credit each Continuing Employee with such employee's unused vacation days accrued by such employee with the applicable Company prior to the Closing Date with respect to the calendar year in which the Closing Date occurs in accordance with the personnel or similar policies applicable to such employees as of the Closing Date.

thereunder by the Buyer and either (A) the receipt by the Buyer of a copy of a favorable determination letter issued by the IRS with respect to the Buyer's Pension Plan or (B) other evidence reasonably satisfactory to the Seller that the terms of the Buyer's Pension Plan and its related trust qualify under section 401(a) and section 501(a) of the Code, the Seller shall direct the trustees of the Long Island Pension Plan, LI Non Union CB Plan, Local 1-2 Plan, RAV Management Pension Plan, New York Pension Plan, and Cash Balance Pension Plan (collectively, the "Seller Pension Plans") to transfer assets having a value as of the actual date of such transfer (the "Actual Transfer Date") equal to the value of the accrued benefit liabilities with respect to the Continuing Employees under the Seller Pension Plans determined as of the Actual Transfer Date in accordance with sections 401(a)(12) and 414(l) of the Code and Treasury Regulation Section 1.414(l)-1(b)(5) (such amount, the "414(l) Required Amount") from the trust(s) under the Seller Pension Plans to the trust under the Buyer's Pension Plan. If the 414(l) Required Amount exceeds the Agreed Upon Transfer Amount the Buyer shall pay to the Seller an amount equal to (1) the 414(l) Required Amount less (2) the Agreed Upon Transfer Amount and such payment shall be deemed to be an adjustment to the Purchase Price. If the Agreed Upon Transfer Amount exceeds the 414(l) Required Amount, the Seller shall pay to the Buyer an amount equal to (1) the Agreed Upon Transfer Amount less (2) the 414(l) Required Amount and such payment shall be deemed to be an adjustment to the Purchase Price. The determination of the 414(l) Required Amounts and Agreed Upon Transfer Amounts shall be determined by the Seller's Actuary and shall be communicated to the Buyer not later than ten (10) Business Days following the applicable Actual Transfer Date. The Buyer shall have the right to appoint an independent actuary ("Buyer's Actuary") for the purpose of verifying the calculation of the 414(l) Required Amounts and Agreed Upon Transfer Amounts. The Seller's Actuary shall deliver to the Buyer's Actuary such supporting documents and information as Buyer's Actuary may reasonably request. Within thirty (30) days following receipt by the Buyer's Actuary of the calculation of the 414(l) Required Amounts and Agreed Upon Transfer Amounts and any reasonably requested supporting documentation and information, the Buyer shall notify the Seller in writing if the Buyer's Actuary disagrees with the calculation made by the Seller's Actuary. If any such disagreement is not resolved to the satisfaction of the Buyer within ninety (90) days of the Seller's receipt of such written notification from Buyer (or within such longer period as the Seller and the Buyer shall mutually agree), the Buyer may elect to have the calculation submitted for arbitration by a third independent actuary mutually acceptable to the Buyer and the Seller, who shall be entitled to the privileges and immunities of an arbitrator, and whose determination shall be conclusive, final and binding and have the force and effect of an arbitral award. The fees and expenses of such third independent actuary will be shared equally by the Buyer and the Seller. As of the applicable Actual Transfer Date the Buyer's Pension Plan shall assume all liabilities for all accrued benefits, including all ancillary benefits, under the Seller Pension Plans in respect of the Continuing Employees with respect to whom assets and liabilities were transferred and each of the Seller and the Seller Pension Plans shall be relieved of all liabilities for such benefits. Upon the transfer of pension assets in accordance with this Section 7.9(e), the Buyer agrees to indemnify and hold harmless the Seller, its Affiliates and their respective Representatives from and against any and all Losses arising out of or related to the Buyer's Pension Plan, in respect of the Continuing Employees, including benefits accrued by the Continuing Employees prior to the Closing Date that are provided by the Buyer's Pension Plan, and the Seller shall have no further obligation with respect to such assumed obligations. The Buyer and the Seller shall provide each other such records and information as may be

necessary or appropriate to carry out their obligations under this Section 7.9(e) or for the purposes of administration of the Buyer's Pension Plan, and they shall cooperate in the filing of documents required by the transfer of assets and liabilities described herein. Notwithstanding anything contained herein to the contrary, no such transfer shall take place until the 31^st day following the filing of all required Forms 5310 in connection therewith.

(f) 401(k) Plan. Effective as of the Closing Date, the Buyer shall maintain or designate a defined contribution plan and related trust intended to be qualified under sections 401(a), 401(k) and 501(a) of the Code (the "Buyer 401(k) Plan"). Effective as of the Closing Date, the Continuing Union Employees shall cease participation in the Seller's relevant defined contribution plans (collectively, the "Seller Union 401(k) Plans"), and shall commence participation in the Buyer 401(k) Plan. As soon as practicable after the Closing Date (but in any event not before any required filings with the IRS have become effective), the Seller shall cause the trustee of the trusts established under the Seller Union 401(k) Plans to transfer to the trustee of the trust established under the Buyer 401(k) Plan all assets and liabilities attributable to the accounts of the Continuing Union Employees under the Seller Union 401(k) Plans as of the date of such transfer (including all applicable plan loans), and the Buyer shall cause the trustee of the trust established under the Buyer 401(k) Plan to accept such transfer. Until such time as assets are transferred from the Seller Union 401(k) Plans to the Buyer 401(k) Plan as contemplated in the foregoing provisions of this Section 7.9(f), the Seller and the Buyer shall cooperate to take such steps as may be necessary to permit any Continuing Union Employee with an outstanding plan loan under the Seller Union 401(k) Plans as of the Closing Date to make timely loan service payments to the Seller Union 401(k) Plans through the Buyer's payroll deductions. The Buyer shall cause the Buyer 401(k) Plan to accept rollover contributions (including any plan loans) from or on behalf of Continuing Management Employees and Continuing Corporate Employees who receive an eligible rollover contribution (within the meaning of Section 402(f)(2) of the Code) from a defined contribution plan maintained by the Seller.

[REDACTED: Post-closing covenants related to post-retirement health and welfare benefits.]

Effective as of the Closing Date, the Buyer or an Affiliate of the Buyer shall have in effect flexible spending reimbursement accounts under a cafeteria plan qualified under section 125 of the Code (the "Buyer Cafeteria Plan").

In the event the Buyer has not, as of the Closing, obtained the [REDACTED: Name of party – due to confidentiality] Release, (i) the Buyer shall defend, indemnify and hold harmless each of the Seller and its Affiliates (other than the Companies) and their respective Representatives from and against any and all losses, liabilities, damages, obligations, payments, costs, Taxes and expenses (including the costs and expenses of any and all actions, suits, proceedings, assessments, judgments, settlements and compromises relating thereto and reasonable attorneys' fees and reasonable disbursements in connection therewith) incurred by the Seller or any of such Affiliates or their respective Representatives arising out of or relating to the Existing [REDACTED: Name of party – due to confidentiality] Guaranty with respect to any matter relating to events that occur from and after the Closing, and (ii) the Buyer shall not permit either Company or any of their respective Affiliates to (A) renew or extend the term of, (B) increase the obligations under, or (C) transfer to another third party, any loan, lease, contract or other obligation for which the Seller or any of its Affiliates (other than the Companies) is or would reasonably be expected to be liable under the Existing [REDACTED: Name of party – due to confidentiality] Guaranty.

To the extent any Recoverable Insurance Claim is subject to indemnification by the Seller under Article IX of this Agreement, in accordance with Section 9.2(c), any payment by the Seller under Article IX shall be net of any

The Buyer shall use its reasonable best efforts (both before and after the Closing) to obtain: (a) in the case of Item 4 of Section 7.20 of the Seller Disclosure Schedules, an amendment to the contract underlying such guaranty so that the Seller is no longer required to provide a guaranty under such underlying contract and (b) in the case of each of the guaranties set forth on Section 7.20 of the Seller Disclosure Schedules (each, an "Existing KeySpan Guaranty") either, (i) a full and unconditional release of all of the obligations of the Seller under such Existing KeySpan Guaranty, in a form reasonably satisfactory to the Seller, or (ii) a substitute guaranty (or other accommodation) so that the Buyer is substituted in

place of the Seller or any of its Affiliates, as appropriate, of all of the obligations of the Seller under such Existing KeySpan Guaranty such that the Seller may terminate such Existing KeySpan Guaranty upon notice, without further obligation to the Seller (each of (i) or (ii), a "KeySpan Release"). In the event the Buyer has not, as of the Closing, obtained a KeySpan Release with respect to any Existing KeySpan Guaranty, (A) the Buyer shall defend, indemnify and hold harmless each of the Seller and its Affiliates (other than the Companies) and their respective Representatives from and against any and all losses, liabilities, damages, obligations, payments, costs, Taxes and expenses (including the costs and expenses of any and all actions, suits, proceedings, assessments, judgments, settlements and compromises relating thereto and reasonable attorneys' fees and reasonable disbursements in connection therewith) incurred by the Seller or any of such Affiliates or their respective Representatives arising out of or relating to such Existing KeySpan Guaranty from and after the Closing and (B) the Buyer shall not permit either Company or any of their respective Affiliates to (x) renew or extend the term of, (y) increase the obligations under, or (z) transfer to another third party, any loan, lease, contract or other obligation for which the Seller or any of its Affiliates (other than the Companies) is or would reasonably be expected to be liable under such Existing KeySpan Guaranty; provided, however, that the Companies shall be entitled to extend the term of the contract underlying the guaranty listed as Item 1 of Section 7.20 of the Seller Disclosure Schedules on a month-to-month basis for an aggregate extension of up to six (6) months after the Closing Date so long as the Buyer continues to comply with its obligations under this Section 7.20 during such six-month period (including the Buyer’s obligation to continue to use its reasonable best efforts after the Closing to obtain a KeySpan Release with respect to such Existing KeySpan Guaranty). To the extent that the Seller or any of its Affiliates (other than the Companies) has performance obligations under any Existing KeySpan Guaranty, the Buyer shall (1) perform such obligations on behalf of the Seller or such Affiliates or (2) otherwise take such action as reasonably requested by the Seller so as to put the Seller or such Affiliates in the same position as if the Buyer, and not the Seller or such Affiliates, had performed or was performing such obligations. For the avoidance of doubt, but subject to the proviso to the second sentence of this Section 7.20, if any KeySpan Release is not obtained by the Buyer, the Buyer shall cause the Companies or any of its Affiliates, as appropriate, to terminate the underlying contract or agreement related to such Existing KeySpan Guaranty at the end of the term of such contract or agreement without taking into account any extensions or renewals thereof, but in no event later than December 31, 2008.

(b) The Buyer shall indemnify, defend and hold harmless the Seller and its Affiliates and their respective Representatives (each, a "Seller Indemnitee") from and against any and all Indemnifiable Losses asserted against or suffered by any Seller Indemnitee relating to, resulting from or arising out of (i) any breach by the Buyer of any representation or warranty of the Buyer contained in this Agreement; (ii) any breach by the Buyer of any covenant or agreement of the Buyer contained in this Agreement; (iii) except for matters for which a Buyer Indemnitee is entitled to indemnification pursuant to Section 9.2(a)(iv), any violation or alleged violation of, or noncompliance with, Environmental Laws prior to, on or after the Closing Date with respect to the Companies, the Real Property, or any activities associated with the ownership, use or operation of the Applicable Facilities, including in connection with former owners or operators of the Applicable Facilities or the Real Property, including the cost of correcting such violations or noncompliance and fines and penalties arising out of such violations or noncompliance; (iv) except for matters for which a Buyer Indemnitee is entitled to indemnification pursuant to Section 9.2(a)(iv), the release, discharge or disposal of Hazardous Substances prior to, on, or after the Closing Date at, on, in, under or migrating to or from the Real Property or the ownership, use or operation of the Applicable Facilities, by any Person, or exposure of persons to Hazardous Substances (including asbestos) at the Real Property or the

Applicable Facilities prior to, on or after the Closing Date, including the following Liabilities arising from or related to such release or exposure: (A) loss of life, personal injury or property damage, (B) loss, injury or damage to natural resources, and (C) Remediation related to said Release; (v) the storage, transportation, treatment, disposal, discharge, Release or recycling of Hazardous Substances, or the arrangement for such activities, after the Closing Date, at or to any Off-Site Location, by or on behalf of the Companies or otherwise in connection with the ownership, use or operation of the Applicable Facilities or the Real Property; (vi) the Consent Decree; or (vii) the Voluntary Cleanup Agreement; provided, that the foregoing indemnification shall not be limited or proscribed due to any assertion or allegation that the Indemnified Losses arise from the negligence or other violation of statutory or common law standards by the Companies, the Seller or its Affiliates or their respective Representatives in connection with the ownership or operation of the Applicable Facilities or the Real Property on or prior to the Closing Date.

(c) In calculating amounts payable to an Indemnitee, the amount of any Indemnifiable Losses shall be determined without duplication of any other Indemnifiable Loss for which an indemnification claim has been made under any other covenant, agreement, representation or warranty. The amount of any Indemnifiable Loss shall be reduced to the extent that the Indemnitee receives any insurance proceeds or other payment with respect to an Indemnifiable Loss from an unaffiliated party (it being understood that the Companies shall not be considered Affiliates of the Seller or its Affiliates), and to take into account any Tax benefit or loss recognized by the Indemnitee arising from the recognition of the Indemnifiable Loss.

(d) The expiration, termination or extinguishment of any covenant, agreement, representation or warranty shall not affect the parties' obligations under this Section 9.2 if the Indemnitee provided the Indemnifying Party with written notice of the claim or event for which indemnification is sought prior to such expiration, termination or extinguishment.

(e) Subject to the second sentence of this Section 9.2(e), in no event shall the Seller be liable for indemnification pursuant to Section 9.2(a)(i) with respect to (i) any individual item where the Indemnifiable Loss relating thereto is less than $[REDACTED: Specific limits on indemnification] and (ii) any individual item where the Indemnifiable Loss relating thereto is equal to or greater than $[REDACTED: Specific limits on indemnification], unless and until the aggregate of all Indemnifiable Losses which are equal to or greater than $[REDACTED: Specific limits on indemnification] and are incurred or suffered by the Buyer Indemnitees, collectively, exceeds [REDACTED: Specific limits on indemnification]% of the Purchase Price, in which case the Buyer Indemnitiees shall only be entitled to indemnification for such Indemnifiable Losses in excess of such amount; provided, however, that neither the Seller, on the one hand, nor the Buyer, on the other hand, shall be required to make payments for indemnification pursuant to Section 9.2(a)(i) or 9.2(b)(i), as applicable, in an aggregate amount in excess of [REDACTED: Specific limits on indemnification]% of the Purchase Price. The limitations on indemnifications set forth in this Section 9.2(e) shall not apply to (A) any indemnification claim made with respect to a breach of any of the Seller's or Energy's representations and warranties set forth in Section 5.1, Section 5.2, Section 5.4(b), Section 5.6, the last sentence of Section 5.7(d), Section 5.10(e),

Section 5.11(a)(C), Section 5.11(e), Section 5.15 or Section 5.20, (B) an indemnification claim made pursuant to Section 7.7(d), or (C) any Claim in law or equity based on fraud.

(f) In addition to the other limitations set forth in this Article IX, with respect to any claim for indemnification regarding any breach of any representation and warranty set forth in Section 5.8: (i) to the extent applicable, the Seller's indemnification obligation shall be limited to the cost of the least restrictive standard or remedy acceptable under applicable Environmental Law (including engineering or institutional controls) based on the industrial use of the relevant facility or property; provided, that the use of such standards or engineering or institutional controls does not materially interfere with operations at the affected facility; and (ii) if any contamination at any Real Property that is subject to indemnity by the Seller is exacerbated due to the negligence, gross negligence or willful misconduct of the Buyer or the Companies after the Closing Date, to the extent such exacerbation increases the cost of the investigation or remediation of such contamination, the Seller shall not be responsible for any such increase in costs.

(g) If and to the extent that prior to the Closing a party has expressly waived in writing the breach of or inaccuracy in a representation or warranty or the failure to perform a covenant or agreement made by the other party, and the Closing nonetheless occurs, then such party shall not have the right to assert a claim for indemnification in respect of such breach, inaccuracy or failure to perform, and the party against whom such claim could otherwise be asserted shall have no liability or obligation in respect thereof.

(h) From and after the Closing, except as otherwise provided in Section 3.2, Section 7.2, Section 7.7(d), Section 7.9(b)(v), Section 7.9(e), Section 7.15(b), Section 7.20, Section 10.3, or Section 11.7 and except for any Claims in law or equity based on fraud, the rights and remedies of the Seller and the Buyer under this Article IX are exclusive and in lieu of any and all other rights and remedies which the Seller and the Buyer may have under this Agreement or otherwise for monetary relief with respect to (i) any breach of any representation or warranty set forth in this Agreement or (ii) any breach or failure to perform any covenant or agreement set forth in this Agreement. Without limiting the foregoing, but subject to the terms of this Agreement, the Buyer, for itself and its Affiliates and on behalf of their respective successors and assigns, does hereby irrevocably release, hold harmless and forever discharge the Seller and its Affiliates and their respective Representatives from any and all Environmental Claims resulting from or arising out of or in connection with any Environmental Condition or Hazardous Substances or Environmental Law, other than Claims arising from a breach of the representations or warranties set forth in Section 5.8 (Environmental Matters) and other than as set forth in Section 9.2(a)(iv) (collectively, "Released Environmental Claims"). In furtherance of, but subject to, the foregoing, the Buyer, for itself and on behalf of its successors and assigns, hereby irrevocably waives any and all rights and benefits with respect to such Environmental Claims that it now has, or in the future may have conferred upon it by virtue of any Law or common law principle, which provides that a general release does not extend to claims which a party does not know or suspect to exist in its favor at the time of executing the release, if knowledge of such claims would have materially affected such party's settlement with the

obligor. In this connection, the Buyer hereby acknowledges that it is aware that factual matters now unknown to it and the Seller or any of its Affiliates may have given, or hereafter may give, rise to Released Environmental Claims that have not been made prior to the date of this Agreement, and will not be made prior to the Closing Date, and the Buyer further agrees that this release set forth in this Section 9.2(h) has been negotiated and agreed upon in light of that awareness, and the Buyer, for itself and its Affiliates and on behalf of their respective successors and assigns, nevertheless hereby intends irrevocably to release, hold harmless and forever discharge the Seller and its Affiliates and their respective Representatives from all such Environmental Claims.

(i) Any indemnification payment by the Seller or the Buyer pursuant to Section 9.2(a) or Section 9.2(b), respectively, shall be treated as an adjustment to the Purchase Price hereunder.

Section 9.3 Defense of Claims.

(a) If any Indemnitee receives notice of the assertion of any Claim or of the commencement of any Claim made or brought by any Person who is not a party to this Agreement or an Affiliate of a party to this Agreement (a "Third Party Claim") with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in any event not later than ten (10) days after the Indemnitee's receipt of notice of such Third Party Claim. Such notice shall describe the nature of the Third Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the Indemnifiable Loss that has been or may be sustained by the Indemnitee; provided, however, that such estimated amount shall in no way limit the Indemnitee's right to recover any amount of Losses over such estimate. The Indemnitee shall not settle any Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), unless the settlement would not require the payment by the Indemnifying Party of any indemnification payment under this Agreement. The Indemnifying Party shall have the right to participate in or, by giving written notice to the Indemnitee, to elect to assume control of the defense of any Third Party Claim at such Indemnifying Party's own expense and by such Indemnifying Party's own counsel, and the Indemnitee shall cooperate in good faith in such defense at such Indemnitee's own expense; provided, however, that the Indemnifying Party's exercise of such right to assume control of such defense shall constitute an acknowledgement without reservation of the Indemnifying Party's obligation to indemnify the Indemnitee with respect to such Third Party Claim; provided further, however, that notwithstanding the Indemnifying Party’s election to assume control of such defense, the Indemnitee shall have the right (but not the obligation) to participate in such defense and to employ counsel, at its own expense, separate from counsel employed by the Indemnitee.

(b) If within ten (10) days after an Indemnitee provides written notice to the Indemnifying Party of any Third Party Claim the Indemnitee receives written notice from the Indemnifying Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in the last sentence of Section 9.3(a), the Indemnifying Party shall not

be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof; provided, however, that if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third Party Claim within twenty (20) days after receiving notice from the Indemnitee that the Indemnitee believes the Indemnifying Party has failed to take such steps, the Indemnitee may assume its own defense, and the Indemnifying Party shall be liable for all reasonable expenses thereof. Without the prior written consent of the Indemnitee, the Indemnifying Party shall not enter into any settlement of any Third Party Claim which would lead to liability or create any financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder. If a firm offer is made to settle a Third Party Claim which could reasonably be expected to lead to liability or the creation of a financial or other obligation on the part of the Indemnitee for which the Indemnitee is entitled to indemnification hereunder and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within ten (10) days after its receipt of such notice, the Indemnitee may continue to contest or defend such Third Party Claim and, in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim shall be the amount of such firm offer, plus reasonable costs and expenses paid or incurred by the Indemnitee up to the date of such notice.

(c) Any Claim by an Indemnitee on account of an Indemnifiable Loss which does not result from a Third Party Claim (a "Direct Claim") shall be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, stating the nature of such Claim in reasonable detail and indicating the estimated amount, if practicable, but in any event not later than ten (10) days after the Indemnitee becomes aware of such Direct Claim; provided, however, that any such estimated amount shall in no way limit the Indemnitee's rights to recover any amount of Losses over such estimate. The Indemnifying Party shall have a period of thirty (30) days within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such thirty (30) day period, the Indemnifying Party shall be deemed to have accepted such Claim. If the Indemnifying Party rejects such Claim, the Indemnitee shall be free to seek enforcement of its rights to indemnification under this Agreement.

(d) If the amount of any Indemnifiable Loss, at any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any Claim, recovery, settlement or payment by or against any other entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith (together with interest thereon from the date of payment thereof at the prime rate then in effect of Citibank N.A.), shall promptly be repaid by the Indemnitee to the Indemnifying Party. Nothing in this Section 9.3(d) shall be construed to require any party hereto to obtain or maintain any insurance coverage.

(e) A failure to give timely notice as provided in this Section 9.3 shall not affect the rights or obligations of any party hereunder except if, and only to the extent that, as a result of such failure, the party which was entitled to receive such notice was actually prejudiced as a result of such failure.

ARTICLE X

TERMINATION AND ABANDONMENT

Section 10.1 Termination. This Agreement may be terminated at any time prior to the Closing Date:

(a) by mutual written consent of the Buyer and the Seller;

(b) by either the Seller or the Buyer if the transactions contemplated by this Agreement shall not have been consummated on or before [REDACTED: Specific date] (the "Termination Date"); provided, however, that the right to terminate this Agreement under this Section 10.1(b) shall not be available to (i) the Seller, if the Seller’s or Energy’s failure to fulfill any of its obligations under this Agreement (including any failure to perform its obligations under Section 4.3 or 4.5) or violation or breach of any covenant, agreement, representation or warranty contained in this Agreement (including any violation or breach that is the subject of any notice delivered by the Buyer pursuant to Section 10.1(d)) has been the cause of, or has resulted in, the failure of the Closing to occur on or before such date; or (ii) the Buyer, if the Buyer’s failure to fulfill any of its obligations under this Agreement (including any failure to pay the Estimated Purchase Price or perform its obligations under Section 4.4) or violation or breach of any covenant, agreement, representation or warranty contained in this Agreement (including any violation or breach that is the subject of any notice delivered by the Seller pursuant to Section 10.1(e)) has been the cause of, or has resulted in, the failure of the Closing to occur on or before such date; provided, further, that if on the Termination Date the conditions to the Closing set forth in Section 8.2(d) or 8.3(d) shall not have been fulfilled but all other conditions to the Closing shall be fulfilled (other than conditions to be satisfied at Closing, which conditions shall be capable of being fulfilled on December 31, 2008 as a condition precedent to such extension), then the Termination Date shall be extended until [REDACTED: Specific date];

(c) by either the Seller or the Buyer if (i) any Governmental Authority, the consent of which is a condition to the obligations of the Seller and the Buyer to consummate the transactions contemplated by this Agreement, shall have determined not to grant its consent and all appeals of such determination, to the extent available, shall have been taken and have been unsuccessful, or (ii) any court of competent jurisdiction in the United States or any state shall have issued an order, judgment or decree permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such Governmental Order shall have become final and nonappealable;

(d) by the Buyer, if there has been a violation or breach by the Seller or Energy of any covenant, agreement, representation or warranty contained in this Agreement which has rendered the satisfaction of any condition to the obligations of the Buyer impossible and such violation or breach has not been cured by the Seller or Energy within sixty (60) Business Days after the Buyer delivers to the Seller a written notice of such violation or breach; and

(e) by the Seller, if there has been a violation or breach by the Buyer of any covenant, agreement, representation or warranty contained in this Agreement which has rendered the satisfaction of any condition to the obligations of the Seller impossible and such violation or breach has not been cured by the Buyer within sixty (60) Business Days after the Buyer delivers to the Seller a written notice of such violation or breach.

Section 10.2 Procedure and Effect of Termination. In the event of termination of this Agreement and abandonment of the transactions contemplated by this Agreement by either or both of the parties pursuant to Section 10.1, written notice thereof shall forthwith be given by the terminating party to the other party and this Agreement shall terminate and the transactions contemplated by this Agreement shall be abandoned, without further action by any of the parties hereto; provided, however, that Section 7.2(b), Section 7.3, and Article XI shall survive terminate of this Agreement. If this Agreement is terminated as provided herein:

(a) nothing herein, except as set forth in Section 10.3, shall relieve any party from liability for damages actually incurred as a result of a breach of any representation, warranty, covenant or agreement of such party contained in this Agreement, provided that the Seller's and the Buyer's remedies shall be limited to the provisions of Section 10.3 (to the extent applicable); and

(b) all filings, applications and other submissions made pursuant to this Agreement, to the extent practicable, shall be withdrawn from the agency or other person to which they were made.

Section 10.3 Break-up Damages.

(a) If this Agreement is terminated by the Seller pursuant to Section 10.1(e) and if the basis for such termination is that the Buyer has breached its obligation to consummate the Closing in accordance with Article IV (including by failure to pay the Estimated Purchase Price or perform its obligations under Section 4.4), then, in lieu of all other Claims and remedies that might otherwise be available to the Seller or Energy with respect to any such breach and such termination and as the Seller's and Energy’s exclusive remedy therefor notwithstanding any other provision of this Agreement, the Buyer shall pay the Seller, by wire transfer of immediately available funds within three (3) Business Days following the date of termination, as liquidated damages, an amount equal to [REDACTED: Specific percentage] of the Estimated Purchase Price (the "Break-up Damages"). If this Agreement is terminated by the Buyer pursuant to Section 10.1(d) and if the basis for such termination is that the Seller or Energy has breached its obligation to consummate the Closing in accordance with Article IV (including by failure to perform its obligations under Sections 4.3 and 4.5), then, in lieu of all other Claims and remedies that might otherwise be available to the Buyer with respect to any such breach and such termination and as the Buyer's exclusive remedy therefor notwithstanding any other provision of this Agreement, the Seller shall pay the Buyer, by wire transfer of immediately available funds within three (3) Business Days following the date of termination, as liquidated damages, the Break-up Damages.

(b) On the date hereof, each of the Buyer and the Seller will cause to be delivered to the other party a guaranty agreement executed by the Buyer's Guarantors or the Seller's Guarantor, as applicable, pursuant to which the Buyer's Guarantors or the Seller's Guarantor, as the case may be, have guaranteed the payment and performance obligations of the Buyer or the Seller, as applicable, for the Break-up Damages (each, a "Break-up Guaranty"). If the applicable party pays the Break-up Damages in full by the time required, then each party shall simultaneously terminate the other party's Break-up Guaranty. If the applicable party does not pay the Break-up Damages in full by the time required, then (i) the other party may enforce its rights to receive payment of the Break-up Damages under the applicable Break-up Guaranty, and (ii) such applicable party shall immediately return to the other party such other party's Break-up Guaranty.

(c) The provision for payments of liquidated damages in this Section 10.3 has been included because, in the event of a breach by a party of its obligation to consummate the Closing, the actual damages to be incurred by the other party or parties can reasonably be expected to approximate the amount of liquidated damages provided for herein and because the actual amount of such damages would be difficult if not impossible to measure accurately.

ARTICLE XI

Notwithstanding the foregoing, the Buyer shall be permitted to assign its rights, interests or obligations in this Agreement to an Affiliate without the prior written consent of the Seller but in no event shall the Buyer's Guarantors be released from their obligations under the Buyer Parent Guaranty as a result of any such assignment. Without limiting the generality of the

foregoing, no provision of this Agreement will create any third-party beneficiary rights in any Person, including any employee or former employee of the Seller or any of their Affiliates (including any beneficiary or dependent thereof) in respect of continued employment, and no provision of this Agreement will create any rights in any such Persons in respect of any benefits that may be provided, directly or indirectly, under any employee benefit plan or arrangement except as expressly provided for thereunder.

Section 11.5 Consent to Jurisdiction and Service of Process; Waiver of Jury Trial.

(a) All judicial proceedings brought against the parties arising out of or relating to this agreement, or any obligations hereunder, shall be brought exclusively in any courts of the United States of America for the Southern District of New York. By executing and delivering this agreement, the parties, irrevocably (i) accept generally and unconditionally the exclusive jurisdiction and venue of these courts; (ii) waive any objections which such party may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this agreement brought in the courts referred to in clause (i) above and hereby further irrevocably waive and agree not to plead or claim in any such court that such action or proceeding brought in any such court has been brought in an inconvenient forum; (iii) agree that service of all process in any such proceeding in any such court may be made by registered or certified mail, return receipt requested, to such party at their respective addresses provided in accordance with Section 11.3; and (iv) agree that service as provided in clause (iii) above is sufficient to confer personal jurisdiction over such party in any such proceeding in any such court, and otherwise constitutes effective and binding service in every respect.

(b) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER DOCUMENT DELIVERED IN CONNECTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE PARTIES. EACH OF THE PARTIES TO THIS AGREEMENT ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER DOCUMENT DELIVERED IN CONNECTION HEREWITH TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR SUCH PARTY ENTERING INTO THIS AGREEMENT AND EACH SUCH OTHER DOCUMENT.

Section 11.6 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of New York (regardless of the Laws that might otherwise govern under applicable New York principles of conflicts of Law) as to all matters, including matters of validity, construction, effect, performance and remedies.

Section 11.7 No Consequential Damages. Notwithstanding anything to the contrary in this Agreement, the Buyer shall not be liable to the Seller or Energy, nor shall the

Seller or Energy be liable to the Buyer, for any exemplary, punitive, special, indirect, consequential, remote or speculative damages (including any damages on account of lost profits or opportunities) resulting from or arising out of this Agreement or the Ancillary Agreements or the transactions contemplated hereby or thereby, except to the extent that any such damages are included in Indemnifiable Losses resulting from a Third Party Claim; provided, however, that the foregoing limitation shall not be applicable to any indemnification claim made with respect to a breach of the Seller's representations in Section 5.11(a)(C).

Section 11.8 Entire Agreement. This Agreement and the Ancillary Agreements, including the documents, exhibits, schedules, certificates and instruments referred to herein and therein, embody the entire agreement and understanding of the parties hereto in respect of the transactions contemplated by this Agreement. There are no restrictions, promises, representations, warranties, covenants or undertakings, other than those expressly set forth or referred to herein or therein. It is expressly acknowledged and agreed that, except to the extent included in the representations and warranties contained in this Agreement, there are no restrictions, promises, representations, warranties, covenants or undertakings of the Seller or the Buyer contained in any material made available to the Buyer pursuant to the terms of the Confidential Information Memorandum, dated December, 2007, or the divestiture-related correspondence previously made available to the Buyer by the Seller and Merrill Lynch, Pierce, Fenner & Smith Incorporated. This Agreement supersedes all prior agreements and understandings between the parties with respect to the transactions contemplated by this Agreement.

Section 11.9 Severability. If any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof.

Section 11.10 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.

IN WITNESS WHEREOF, each of the Seller, the Buyer and Energy have caused this Agreement to be signed by their respective duly authorized officers as of the date first above written.

Section 2.2 Sublease Subject to the Facility Lease.

(a) The Sublessor and the Sublessee acknowledge and agree that this Facility Sublease is subject and subordinate to all of the terms and conditions of the Facility Lease, including, without limitation, the Owner Lessor’s rights thereunder. Neither the Sublessor nor any of its Affiliates shall be deemed to have assumed any duty or obligation of the Owner Lessor under the Facility Lease and shall not be liable or responsible in any manner whatsoever for any failure of the Owner Lessor to perform any such duty or obligation. The Sublessee will abide by, comply in all respects with, and fully and completely perform all terms, covenants, conditions, and provisions of the Facility Lease and the other Designated Operative Documents (including, without limitation, terms, covenants, conditions, and provisions relating to operation, maintenance, insurance and alterations) as if the Sublessee were the Lessee under the Facility Lease and the other Designated Operative Documents, provided however, that the Sublessee’s obligations under the Designated Operative Documents assumed hereunder shall not include any of the following obligations of the Lessee, all of which shall remain obligations of the Sublessor as the Lessee under the Facility Lease: (i) obligations under Section 3.2 and Section 22.13 of the Facility Lease and (ii) Sections 5.1, 5.2, 5.3 (with respect to any Lease Default or Lease Event of Default which constitutes a Seller Event of Default), 5.4, 5.5, clause (B) of 5.6(a) and related obligations under 5.6(b) (for as long the Sublessor owns the Facility Site and to the extent such obligations relate to the Facility Site), 5.7 (except to the extent such obligation relates to the Facility) 5.8, 5.9, 5.11, 5.12, 9.1 (except to the extent of the Sublessee’s indemnity obligations under Section 20 hereof) and 9.2 (except to the extent of the Sublessee’s indemnity obligations under Section 21 hereof) of the Participation Agreement (collectively, the “Sublessor Retained Obligations”).

To the extent that the Facility Lease or any other Designated Operative Document imposes or requires the performance of the Lessee thereunder of any duty or obligation that is more stringent than or in conflict with

any term, covenant, condition, or provision of this Facility Sublease, the applicable term, covenant, condition, or provision of the Facility Lease or such other Designated Operative Document will control and will constitute the duties and obligations of Sublessee under this Facility Sublease as to the subject matter of such term, covenant, condition, or provision. The Sublessee will not engage in or permit any conduct that would: (i) constitute a breach of or default under the Facility Lease; or (ii) result in the Owner Lessor being entitled to terminate the Facility Lease or to terminate the Sublessor’s right as lessee under the Facility Lease, or to exercise any other rights or remedies to which the Owner Lessor may be entitled for a default or breach under the Facility Lease.

(c) The Sublessee will not be entitled to act as agent for, or otherwise on behalf of, the Sublessor or its Affiliates or to bind the Sublessor or its Affiliates in any way whatsoever in connection with the Facility Lease, any other Operative Document or otherwise except as provided in this Section 2.2.

In accordance with the provisions of this Facility Sublease, except in respect of any Sublessor Retained Obligations, Sublessor Reserved Matters or Retained Operative Documents, the Sublessee will have the sole and exclusive right to review, negotiate and execute on behalf of Sublessor amendments and other documentation relating to the Facility and the Facility Site (including the operation and maintenance thereof) and to otherwise act on behalf of the Sublessor in dealing with the Financing Parties under the Facility Lease and the Designated Operative Documents including with respect to the matters relating to the Facility and the

Facility Site (including the operation and maintenance thereof), and the Sublessor hereby grants to the Sublessee an irrevocable power of attorney, coupled with an interest, and, subject to any limitation on such appointment herein, appoints the Sublessee as its agent and attorney to review, negotiate and execute on behalf of the Sublessor amendments and other documentation relating to the Facility and the Facility Site (including the operation and maintenance thereof) and to otherwise act on behalf of the Sublessor in dealing with the Financing Parties with respect to the matters relating to the Facility and the Facility Site (including the operation and maintenance thereof). The foregoing power of attorney and appointment are subject to the following requirements and limitations: (i) all amendments and other documentation executed by the Sublessee, and actions taken by the Sublessee on behalf of the Sublessor must comply in all respects with the requirements and provisions of this Facility Sublease, (ii) the foregoing power of attorney does not apply to any termination, extension or renewal of the Facility Lease, any amendment to, modification of or consent under any Retained Operative Document, any Sublessor Retained Obligation or any Sublessor Reserved Matter, (iii) upon request by the Sublessor, the Sublessee will provide the Sublessor with such summaries, documentation and other information relating to the Sublessee’s negotiations and other activities pertaining to the Facility Lease or any other Facility Sublease Document as the Sublessor or any of its Affiliates may reasonably request, and (iv) the foregoing power of attorney and appointment granted herein to the Sublessee (x) may be suspended by written notice from the Sublessor to the Sublessee at any time upon the occurrence of a Sublease Event of Default or if the Sublessee violates or fails to comply with the foregoing requirements and limitations and until such violation or failure is cured and (y) shall automatically terminate upon the termination of this Facility Sublease. The Sublessee will, and does hereby agree to, indemnify, defend and hold the Sublessor and all of its Affiliates harmless from, against and in respect of any and all Claims asserted against, paid, suffered, incurred or sustained by the Sublessor or any of its Affiliates and in any manner arising out of, by reason of, or in connection with all deeds and activities performed by the Sublessee pursuant to and under the authority granted by the power of attorney granted in this Section 2.2(c) (including, without limitation, a violation of or failure to comply with the foregoing requirements and limitations).

(d) Upon receipt by the Sublessor of any notice of default or notice of an act or omission which could with the passing of time and/or the giving of notice constitute an event of default under the Facility Lease or non-compliance with a term of the Facility Lease (the “Default Notice”), the Sublessor will, within five (5) Business Days after receipt of the Default Notice or to the extent practical under the circumstances such shorter time as is reasonably necessary to avoid a termination of the Facility Lease, provide the Sublessee with a copy of the Default Notice. If such default or non-compliance with a term of the Facility Lease is caused by the Sublessee's failure to perform its obligations hereunder, the Sublessee shall cure or otherwise remedy such default or noncompliance within the time frames for the exercise of such cure rights by the Lessee set forth under the Facility Lease.

(e) During the Facility Sublease Term, for any dispute or litigation arising out of or in connection with the Facility Lease or any other issue relating to the operation or maintenance of the Facility, including any Claim (collectively, “Disputes”), the Sublessee shall have the right to control, prosecute, settle and compromise such Disputes; provided that the

(iii) Non-Contravention. The execution, delivery and performance of this Facility Sublease and other Facility Sublease Documents do not and will not (A) contravene any Applicable Law binding on the Sublessee or its property, (B) require any action, consent or approval by any trustee or holder of indebtedness of the Sublessee (other than those obtained prior to the date hereof) or (C) constitute a violation of or a default under any indenture, mortgage or other material contract to which the Sublessee is a party or by which any of its property is bound, which in any case, individually or in the aggregate, is reasonably likely to result in a Material Adverse Effect.

Section 3.

FACILITY SUBLEASE TERM AND RENT

Section 3.1 Basic Sublease Term. The basic term of this Facility Sublease (the “Basic Sublease Term”) shall commence on the Sublease Closing Date and shall terminate at 11:59 p.m. (New York City time) on May 25, 2040 (the “Sublease Expiration Date”), subject to earlier termination pursuant to Section 10 or Section 17 hereof.

Section 3.2 Rent.

(a) Payment of Sublease Base Rent. The Sublessee hereby agrees to pay to the Sublessor on each Basic Sublease Rent Payment Date during the Basic Sublease Term, unless this Facility Sublease is earlier terminated in accordance with the express provisions hereof, the amount set forth opposite such Basic Sublease Rent Payment Date on Schedule A-1 hereto (“Sublease Base Rent”).

(b) Prepayment of Sublease Base Rent upon Change of Control. Upon occurrence of the Change of Control of the Sublessee, the Sublessee shall prepay the net present value of all Sublease Base Rent as determined using the Discount Rate and as set forth on Schedule A-2 hereto (the "NPV of Sublease Base Rent"). Such prepayment of the Sublease Base Rent shall constitute compensation to the Sublessor for the sublease of the Facility to the Sublessee under this Facility Sublease and shall fully satisfy the obligation of the Sublessee to pay Sublease Base Rent under this Facility Sublease.

(i) Initial Allocations. The Sublease Base Rent will be allocated in the amounts and to the periods as set forth in Schedule A-3, column

“b”, hereto (the “Allocated Rent”). Within each full or partial calendar year during the Basic Sublease Term (each, a “Rental Period”), Sublease Base Rent shall be allocated on a level basis by month and on a level daily basis within each month. It is the intention of the Sublessor and the Sublessee that the allocation of Sublease Base Rent to each Rental Period as provided in this Section 3.2(c)(i) constitutes a specific allocation of fixed rent within the meaning of Treasury Regulation section 1.467-1(c)(2)(ii).

(ii) Proportional Rent Amounts. Because the amount prepaid by the Sublessee pursuant to Section 3.2(b) as the net present value of all Sublease Base Rent exceeds the sum of the present values of the Allocated Rent set forth on Schedule A-3, column “b”, hereto (as determined using the Applicable Federal Rate of 4.65%, compounded annually, as the discount rate), the fixed rent for each rental period is the “proportional rental amount” as required by Treasury Regulation section 1.467-2(a). Such “proportional rental amount”, calculated in accordance with Treasury Regulation section 1.467-2(c)(1), equals, in each Rental Period, the Allocated Rent for such period multiplied by a fraction, the numerator of which equals the amount shown as the “Rent Payment” on July 15, 2008, on Schedule A-3, column “a”, hereto and the denominator of which equals the sum of the present values of the Allocated Rent shown on Schedule A-3, column “b”, hereto calculated as described in the first sentence of this paragraph (ii).

(iii) Prepaid Rent Amounts and Interest on Prepaid Rent. Because, as of the close of each Rental Period, the prepaid rent shown as the “Rent Payment” on Schedule A-3, column “a”, hereto reduced by the absolute value of cumulative 467 Interest as shown on Schedule A-3, column “j”, hereto exceeds the cumulative amount of 467 Proportional Rental Accruals as shown on Schedule A-3, column “g”, hereto it is the intention of the Sublessor and the Sublessee that such excess constitutes prepaid rent within the meaning of Treasury Regulation section 1.467-1(c)(3)(ii) and interest shall accrue thereon at the annual discount rate shown on Schedule A-3 hereto (and equal to 110% of the annual long-term Applicable Federal Rate on the Sublease Closing Date). The Sublessor and the Sublessee on any Federal income tax returns filed by them (or on any Federal income tax returns on which their income is included), shall accrue as interest expense and interest income, respectively, the amount (and only such amount, unless required to do otherwise by the Internal Revenue Service) shown under the heading “467 Interest” (the “Interest on Prepaid Rent”) set forth opposite such Rental Period in column “i” of Schedule A-3 hereto and shall accrue as rental income and rental expense, respectively, the amount (and only such amount, unless required to do otherwise by the Internal Revenue Service) shown as 467 Proportional Rent Accrual set forth opposite such Rental Period in column “g” of Schedule A-3 hereto.

(d) Payment and Allocation of Sublease Renewal Rent. Sublease Renewal Rent, if any, shall be paid as set forth in Section 15 and shall be allocated on a level daily basis over such Renewal Sublease Term.

Section 3.3 Supplemental Sublease Rent. The Sublessee also agrees to pay to the Sublessor any and all Supplemental Sublease Rent, promptly as the same shall become due and owing, or where no due date is specified, promptly after demand by the Sublessor, and in the event of any failure on the part of the Sublessee to pay any Supplemental Sublease Rent, the Sublessor shall have all the same rights, powers and remedies as are provided for herein or by law or equity or otherwise for the failure to pay Sublease Base Rent or Sublease Renewal Rent. The Sublessee will also pay as Supplemental Sublease Rent, to the extent permitted by Applicable Law, an amount equal to interest at the Overdue Rate on any Supplemental Sublease Rent not paid when due (whether on demand or otherwise) for the period from such due date until the same shall be paid. All Supplemental Sublease Rent to be paid pursuant to this Section 3.3 shall be payable in the manner set forth in Section 3.4.

Section 3.4 Manner of Payments. All Sublease Rent shall be paid by the Sublessee in lawful currency of the United States of America in immediately available funds to the recipient not later than 10:00 a.m. (New York City time) on the due date therefor. All Supplemental Sublease Rent due on account of Supplemental Lease Rent shall be paid as provided in Section 3.5 of the Facility Lease. All other Sublease Rent shall be paid by the Sublessee to the Sublessor by payment to the Sublessor’s Account or to such other place as the Sublessor shall notify the Sublessee in writing reasonably in advance of such payment. The Sublessee agrees that, except pursuant to Section 10.2 (b) and Section 10.3 and any provision of this Facility Sublease which expressly provides for the same, the Sublease Rent is non-refundable and that the Sublessee will not have any right of abatement, reduction, set-off, counterclaim, rescission, refund, defense or deduction with respect thereto.

It is agreed that all such risks, as between the Sublessor on the one hand and the Sublessee on the other hand are to be borne by the Sublessee with respect to acts, occurrences or omissions during the Facility Sublease Term. The Sublessor shall not have any responsibility or liability to the Sublessee or any other Person with respect to any of the following occurring during the Facility Sublease Term: (x) any liability, loss or damage caused or alleged to be caused directly or indirectly by the Facility or any Component or by any inadequacy thereof or deficiency or defect therein or by any other circumstances in connection therewith; (y) the use, operation or performance of the Facility or any Component thereof or any risks relating thereto; or (z) the delivery, operation, servicing, maintenance, repair, improvement, replacement or decommissioning of the Facility or any Component thereof. The provisions of this paragraph (a) of this Section 4.1 have been negotiated, and, except for the representations and warranties set forth in Section 2.3(a) hereof and the MISPA, the foregoing provisions are intended to be a complete exclusion and negation of any representations or warranties of the Sublessor, express or implied, with respect to the Facility or any Component thereof that may arise pursuant to any Applicable Law now or hereafter in effect, or otherwise.

(b) During the Facility Sublease Term, so long as no Sublease Event of Default shall have occurred and be continuing, the Sublessor hereby appoints irrevocably and constitutes the Sublessee its agent and attorney-in-fact, coupled with an interest, to assert and enforce, from time to time, in the name and for the account of the Sublessor, at the sole cost and expense of the Sublessee, whatever claims and rights the Sublessor may have in respect of the Facility or any Component thereof against any manufacturer, vendor or contractor, or under any express or implied warranties relating to the Facility or any Component thereof.

Section 4.2 Quiet Enjoyment.

(a) The Sublessor acknowledges notice of the Site Sub-Sublease and expressly agrees that, so long as no Sublease Event of Default has occurred and is continuing, neither the Sublessor nor any party acting by, through or under the Sublessor shall take or cause to be taken any action contrary to the Sublessee’s rights under this Facility Sublease and the Site Sub-sublease, including the right to possession, use and quiet enjoyment of the Facility, the Facility Site and the Easements. So long as no Sublease Event of Default has occurred and is continuing, in the event of a bankruptcy of the Owner Lessor, without the prior written consent of the Sublessee, the Sublessor shall not exercise, or refrain from exercising, any rights that it might have or obtain pursuant to section 365(h) of title 11, United States Code.

(b) The Sublessee and the Sublessor agree that at any time prior to the Transfer Date if any Seller Event of Default results in a termination of the Facility Lease and loss by the Sublessee of its right of possession, use and quiet enjoyment of the Facility, the Sublessor shall pay to the Sublessee the Unamortized Portion of the Purchase Price (in which case provisions of Section 10.3 shall not apply) as of the applicable Sublease Termination Date, and such payment will be the sole and exclusive remedy of the Sublessee on account of any termination of this Facility Sublease and the Facility Lease due to a Sublessor Event of Default. The Sublessee hereby expressly waives and relinquishes any and all other remedies at law or in equity it may have against the Sublessor or any of its Affiliates on account of such event. The Sublessor shall have the right to apply amounts owed to the Sublessee pursuant to this Section 4.2(b) against any and all amounts owed to the Sublessor by the Sublessee on such Sublease Termination Date (including any amounts which may be owed pursuant to Section 17.1).

Section 5.

Section 5.1 Return. Upon expiration or early termination of this Facility Sublease, the Sublessee, at its own expense, shall return the Facility (together with any Modifications to the Facility title to which shall have vested in the Owner Lessor pursuant to Section 8.3) to the Sublessor or any transferee or assignee of the Sublessor by surrendering the Facility into the possession of the Sublessor or such transferee or assignee at the Facility Site. In connection with such return, the Sublessee shall:

(i) assign, to the extent permitted by Applicable Law, and shall cooperate with all reasonable requests of the Sublessor or any transferee or assignee of the Sublessor for purposes of obtaining, or enabling the Sublessor or such transferees or assignees to obtain, any and all Governmental Approvals and licenses, permits, approvals and consents of any other Persons that are or will be required to be obtained by the Sublessor or such transferee or assignee in connection with the use, operation or maintenance of the Facility on or after such return in compliance with Applicable Law; provided that if any such Governmental Approval or other license, permit, approval or consent also relates to any other facilities, the Sublessee and the Sublessor shall enter into mutually satisfactory arrangements so that the Facility and such other facilities may each be owned, operated and maintained in a commercially reasonable manner;

(ii) provide the Sublessor or a transferee or assignee of the Sublessor copies of all documents (including equipment inspection reports and maintenance records and all Governmental Approvals and related materials), instruments, plans, maps, specifications, manuals, drawings and other documentary materials relating to the installation, maintenance, operation, construction, design, modification and repair of the Facility as shall be in the Sublessee’s possession and shall be reasonably appropriate or necessary for the continued operation of the Facility. Upon such return, the right to use the Facility granted hereunder for the benefit of the Sublessee shall cease and terminate;

(iii) assign any long-term service contracts specifically applicable only to the Facility to the extent such assignment is permitted under such contract without the consent of the counterparty thereto;

(iv) enter into any reasonably requested support arrangements contemplated by Section 5.6 of the Participation Agreement; and

(v) take, execute, acknowledge and deliver such acts, documents and assurances as may be required pursuant to Section 5.7 of the Participation Agreement.

Section 5.2 Condition Upon Return. At the time of the return of the Facility by the Sublessee to the Sublessor or any transferee or assignee of the Sublessor pursuant to Section 5.1, the following conditions shall be complied with, all at the Sublessee’s sole cost and expense; provided that this Section 5.2 shall not apply to any return pursuant to Section 10:

(a) the Facility shall be free and clear of all Liens (other than Permitted Liens of the type specified in (b) (other than Indenture Trustee’s Liens), (h), (i), (j), (k), (1) or (m) of the definition thereof and the interests of the Owner Participant and the Owner Lessor under any of the Operative Documents);

(c) at the request of the Sublessor and to the extent permitted by the Facility Lease, remove all Sublessee’s Severable Modifications and otherwise restore the Facility Site to the condition required by the Facility Lease. Any Sublessee’s Severable Modifications not removed by the Sublessee within thirty (30) days of the expiration or the early termination of this Facility Sublease will, at the Sublessor’s option, be deemed abandoned by the Sublessee and title to such Severable Modifications will automatically, without further action, vest in the Sublessor or its designee.

Section 5.3 Environmental Reports; Clean-up.

(a) In connection with the return of the Facility to the Sublessor at the Sublease Expiration Date or the expiration of the last Renewal Lease Term elected by the Sublessee or pursuant to Section 17, the Sublessee shall, at its own expense, provide the Sublessor (a) not later than nine (9) months prior to the later of the Sublease Expiration Date or the expiration date of the last Renewal Lease Term elected by the Sublessee, or (b) in connection with any return pursuant to Section 17 of this Facility Sublease, as promptly as possible prior to such return, a Phase I Survey (as defined below) as to the environmental conditions or circumstances of the Facility and the Facility Site and the presence or absence of any Environmental Conditions that reasonably could give rise to a liability or a potential liability. Such survey shall be conducted in conformance with American Society for Testing and Materials (“ASTM”) standards for a Phase I environmental site assessment and shall include a review of the compliance or non-compliance of the Facility and Facility Site at the time of the return of the Facility with any applicable Environmental Laws, as then currently in effect (together, a “Phase I Survey”) performed not more than 90 days prior to the date such report is provided to the Sublessor, by a reputable environmental consulting firm (selected by the Sublessee and reasonably acceptable to the Sublessor). The Phase I Survey will only be expanded to a Phase II environmental site assessment conducted in conformance with the ASTM standards (a “Phase II Survey”) if, as a result of the Phase I Survey, facts are revealed that would reasonably necessitate a Phase II Survey; provided however, that such facts were not otherwise previously identified in the scope of work, site investigation results, contaminant fate and transport, conclusions and recommendations sections of the environmental reports listed as items 13, 14 and 21 in Schedule 4(w) to the Participation Agreement. The provisions of such Phase I Survey or Phase II Survey shall not relieve the Sublessee of any indemnification obligation or liability with respect to Environmental Conditions or any non-compliance with Environmental Laws existing at the time of such return, whether known or unknown, in respect of the Facility or the Facility Site.

(b) If the Phase I Survey or Phase II Survey delivered pursuant to Section 5.3(a) indicates that, or at the time of any return of the Facility pursuant to Section 5.1 (other than pursuant to Section 10) the Sublessee has received written notice or otherwise has Actual Knowledge that, any action (including

clean-up, investigation, abatement, correction, removal or remediation) is then required under any then applicable Environmental Laws as then currently in effect (whether indicated in the Phase I Survey or Phase II Survey or otherwise and including any action then required under applicable Environmental Laws (as then currently in effect) for the Facility to be then in compliance with such Environmental Laws), the Sublessee shall, at its own expense, within 90 days of the Sublessor having received such Phase I Survey or Phase II Survey, provide the Sublessor with a remediation plan reasonably satisfactory to the Sublessor designed to effect compliance with then applicable Environmental Laws (as then currently in effect) and the return conditions set forth in this Section 5 as promptly as is reasonably practical (and in any event prior to the expiration of the Facility Sublease Term) and without materially adversely affecting the continued operation of the Facility. To the extent that any action (including clean-up, investigation, abatement, correction, removal or remediation) required to be taken under this Section 5.3(b) cannot reasonably be completed prior to expiration or termination of this Facility Sublease, the Sublessee shall complete such action (including clean-up, investigation, abatement, correction, removal or remediation) as promptly thereafter as is reasonably practical, and in addition the Sublessee shall provide to the Sublessor adequate financial assurance during such period following the end of the Facility Sublease Term with respect to the ability of the Sublessee (or any other Person responsible therefor) to satisfy such obligation. The obligations of the Sublessee set forth in Section 5.3(a) and (b) hereof shall survive the termination of this Facility Sublease and the expiration of the Facility Sublease Term.

(c) Nothing contained in Section 5.3(a) and (b) above shall be construed to waive any right or claim or modify any obligation which any party hereto or any of their respective Affiliates may have pursuant to the MISPA.

Section 5.4 Return upon termination of the Facility Lease. Notwithstanding anything to the contrary in the foregoing Sections 5.1 through and including 5.3, upon the expiration or early termination of this Facility Sublease concurrently with or as a result of the termination of the Facility Lease (whether in accordance with its terms or as a result of any exercise of remedies by the Owner Lessor or any of its successors or assigns), all obligations of the Lessee set forth in Section 5 of the Facility Lease and Section 5.6 and 5.7 of the Participation Agreement (in each case except for the Sublessor Retained Obligations thereunder) shall constitute obligations of the Sublessee hereunder mutatis mutandis and performance by the Sublessee of all such obligations for the benefit of the Owner Participant, the Owner Trustee, the Owner Lessor or any transferees or assignee of any of such parties resulting in full and unconditional satisfaction of the Sublessor’s obligations to such parties shall constitute performance by the Sublessee of its obligations hereunder and shall fully discharge such obligations.

Section 6.

LIENS

(a) The Sublessee will not directly or indirectly create, incur, assume or suffer to exist any Lien on or with respect to the Facility (or any Component thereof), the Ground Interest, the Operative Documents or the Facility Sublease Documents or the Sublessor’s interest therein, except Permitted Liens, other than of the type specified in clause (c) of the definition thereof. The Sublessee shall promptly notify the Sublessor of the imposition of any such Lien of which the Sublessee has Actual Knowledge and shall promptly at its own expense take such action as may be necessary to fully discharge and release such Lien. If the Sublessee fails to cause any Lien (except Permitted Liens, other than of the type specified in clause (c) of the definition thereof) to be discharged within the permitted time, the Sublessor may cause it to be discharged and may pay (but shall be under no obligation to do so) the amount necessary to discharge such Lien. If the Sublessor makes any such payment, all amounts paid by the Sublessor will be payable by the Sublessee to the Sublessor as Supplemental Sublease Rent within ten (10) days of demand.

(b) Other than the Facility Sublease and the Site Sub-sublease, the Sublessor will not directly or indirectly create, incur, assume or suffer to exist any Lien on or with respect to the Facility (or any Component thereof), the Ground Interest, the Operative Documents or the Facility Sublease Documents or the Sublessee’s interest therein, except

Permitted Liens, other than of the type specified in clause (c) of the definition thereof. The Sublessor shall promptly notify the Sublessee of the imposition of any such Lien of which the Sublessor has Actual Knowledge and shall promptly at its own expense take such action as may be necessary to fully discharge and release such Lien. If the Sublessor fails to cause any Lien (except Permitted Liens, other than of the type specified in clause (c) of the definition thereof) to be discharged within the permitted time, the Sublessee may cause it to be discharged and may pay (but shall be under no obligation to do so) the amount necessary to discharge such Lien. If the Sublessee makes any such payment, all amounts paid by the Sublessee will be payable by the Sublessor to the Sublessee within ten (10) days of demand.

Section 7.

The Sublessee, at its own cost and expense, will (a) cause the Facility to be maintained in good condition, repair and working order, ordinary wear and tear excepted, and in any event in all material respects (i) in accordance with Prudent Industry Practice without discrimination by reason of the subleased status of the Facility as compared to other comparable property owned, leased or subleased by the Sublessee or its Affiliates; (ii) in compliance with all Applicable Laws of any Governmental Entity unless such non-compliance could not reasonably be expected to result in a material adverse effect on (x) the ability of the Sublessee to perform its material obligations under any of the Facility Sublease Documents or (y) the validity or enforceability of any of the Facility Sublease Documents or any Operative Document; provided however, that the Sublessee may, in good faith and by appropriate proceedings, diligently contest the validity or application of any Applicable Law in any reasonable manner that (A) does not involve any risk of foreclosure, sale or forfeiture or loss of the Facility or any substantial part thereof or the Facility Site (in each case, unless such risk is not material) or the impairment of the use, operation or maintenance of the Facility in any material respect, and (B) could not result in any criminal liability being incurred by, or could not reasonably be expected to have any material adverse effect on the interests of the Sublessor, any Financing Party or any of their Affiliates, including subjecting any of the above parties (other than the Sublessor or its Affiliates to the extent already subject to regulation as a public utility, in which case such regulation shall not become materially more burdensome as a result of such contest), to regulation as a public utility under Applicable Law; and (iii) in accordance with the terms of all insurance policies required to be maintained with respect to the Facility pursuant to Section 11; and (b) cause to be made, at its own cost and expense, all repairs, renewals, replacements and improvements thereof, all as in the judgment of the Sublessee may be necessary so that the Facility may be operated in accordance with its intended purpose.

Section 7.2 Replacement of Components. The Sublessee shall have all rights and perform all obligations of the Lessee under Section 7.2 of the Facility Lease. The Sublessor hereby designates the Sublessee to take title to any replaced Component pursuant to Section 7.2 of the Facility Lease. The Sublessee acknowledges and agrees that if any Component to the Facility that is subject to the Facility Lease and this Facility Sublease is removed from the Facility, such Component shall remain subject to the Facility Lease and the other Operative Documents and this Facility Sublease, wherever located, until such time as such Component is replaced by a Replacement Component which has been incorporated into the Facility and which

meets the requirements for the Replacement Component specified in Section 7.2 of the Facility Lease.

The Sublessee, at its sole cost and expense, shall make or cause to be made all Modifications to the Facility as are required (a) by Applicable Law or (b) to maintain in effect any insurance policy required to be maintained with respect to the Facility pursuant to Section 11 hereof (each, a “Required Modification”); providedhowever, that the Sublessee may, in good faith and by appropriate proceedings, diligently contest the validity or application of any Applicable Law in any reasonable manner that (i) does not involve any danger of foreclosure, sale or forfeiture or loss of any part of the Facility or any substantial part thereof or the Facility Site (in each case unless such risk is not material) or impair the use, operation or maintenance of the Facility in any material respect, and (ii) could not result in any criminal liability being incurred by, or could not reasonably be expected to have any material adverse effect on the interests of the Sublessor, any Financing Party or any of their Affiliates, including subjecting any of the above parties (other than the Sublessor or its Affiliates to the extent already subject to regulation as a public utility, in which case such regulation shall not become materially more burdensome as a result of such contest), to regulation as a public utility under Applicable Law.

(i) any setoff, counterclaim, recoupment, defense or other right which the Sublessee may have against the Sublessor or any other Person, including any claim as a result of any breach by any of said parties of any covenant or provision in any Facility Sublease Document or any Operative Document,

No delay or omission to exercise any right, power or remedy accruing to the Sublessor upon any breach or default by the Sublessee under this Facility Sublease shall impair any such right, power or remedy of the Sublessor, nor shall any such delay or omission be construed as a waiver of any breach or default, or of any similar breach or default hereafter occurring; nor shall any waiver of a single breach or default be deemed a waiver of any subsequent breach or default.

Section 18.

NO ASSIGNMENTS, SUBLETTING

The Sublessee may not assign, sell, convey, transfer sublease or otherwise dispose of this Facility Sublease or any of its right hereunder in whole or in part, or sublease or grant concessions, or licenses or other rights for the occupancy or use of all or any portion of the Facility or the Facility Site. The Sublessee hereby agrees that any assignment of its interest in this Facility Sublease shall constitute an event of default hereunder and shall be null and void ab initio.

If the Sublessee fails to make any payment required to be made by it hereunder or under any Facility Sublease Document or fails to perform or comply with any of its other agreements contained herein or obligations under the Facility Lease assumed by it pursuant to Section 2.2 after notice to the Sublessee and failure of the Sublessee to so perform or comply within ten (10) days thereafter in the case of a failure to make any payment or thirty (30) days thereafter in all other cases, the Sublessor may itself make such payment or perform or comply with such agreement in a reasonable manner, but shall not be obligated hereunder to do so, and the amount of such payment and of the reasonable expenses of the Sublessor incurred in connection with such payment or the performance of or compliance with such agreement, as the case may be, together with interest thereon at the Overdue Rate, to the extent permitted by Applicable Law, shall be deemed payable by the Sublessee to the Sublessor on demand.

Section 20.2 Claims Excluded. Any Claim to the extent (A) arising out of or attributable to, (B) in connection with or (C) relating to, any of the following, is excluded from the Sublessee’s agreement to indemnify any Sublessor Indemnitee under this Section 20:

Nothing in this Section 20.2 shall be construed to waive any right or claim which either party hereto (or any of their respective Affiliates) may have pursuant to the MISPA;

(b) any offer, sale, assignment, transfer or other disposition (voluntary or involuntary) by or on behalf of the Sublessor of all or any of its interests in the Facility Lease or the Facility Site, unless such transfer is required by the terms of the Facility Sublease Documents or occurs in connection with the exercise of remedies during continuance of a Sublease Event of Default;

Section 20.3 Insured Claims. Subject to the provisions of Section 20.5, in the case of any Claim indemnified by the Sublessee hereunder which is covered by a policy of insurance maintained by the Sublessee, each Sublessor Indemnitee agrees, unless it and each other Sublessor Indemnitee shall waive its rights to indemnification (for itself and each Related Party thereto) in a manner reasonably acceptable to the Sublessee, to cooperate, at the sole cost and expense of the Sublessee, with insurers in exercise of their rights to investigate, defend or compromise such Claim.

own expense in any judicial proceeding controlled by the Sublessee pursuant to the preceding provisions, but only to the extent that such party’s participation does not in the reasonable opinion of counsel to the Sublessee interfere with such control; provided however, that such party’s participation does not constitute a waiver of the indemnification provided in this Section 20; provided, further, that if and to the extent that (i) such Sublessor Indemnitee is advised by counsel that an actual or potential conflict of interest exists where it is advisable for such Sublessor Indemnitee to be represented by separate counsel or (ii) there is a risk that such Sublessor Indemnitee may be indicted or otherwise charged in a criminal complaint and such Sublessor Indemnitee informs the Sublessee that such Sublessor Indemnitee desires to be represented by separate counsel, such Sublessor Indemnitee shall have the right to control its own defense of such Claim and the reasonable fees and expenses of such defense (including the reasonable fees and expenses of such separate counsel) shall be borne by the Sublessee. So long as no Sublease Event of Default shall have occurred and be continuing, no Sublessor Indemnitee shall enter into any settlement or other compromise with respect to any Claim without the prior written consent of the Sublessee unless (i) the Sublessor Indemnitee waives its rights to indemnification hereunder or (ii) the Sublessee has not acknowledged its indemnity obligation with respect thereto and there is a significant risk that a default judgment will be entered against such Sublessor Indemnitee. Nothing contained in this Section 20.4 shall be deemed to require any Sublessor Indemnitee to contest any Claim or to assume responsibility for or control of any judicial proceeding with respect thereto.

Section 20.5 Subrogation. To the extent that a Claim indemnified by the Sublessee under this Section 20 is in fact paid in full by the Sublessee or an insurer under an insurance policy maintained by the Sublessee, the Sublessee (so long as no Sublease Event of Default shall have occurred and be continuing) or such insurer shall be subrogated to the rights and remedies of the Sublessor Indemnitee on whose behalf such Claim was paid to the extent of such payment (other than rights of such Sublessor Indemnitee under insurance policies maintained at its own expense or rights of the Owner Trustee under the Trust Agreement) with respect to the transaction or event giving rise to such Claim. Should a Sublessor Indemnitee receive any refund, in whole or in part, with respect to any Claim paid by the Sublessee hereunder, it shall promptly pay over to the Sublessee the lesser of (i) the amount refunded reduced by the amount of any Tax incurred by reason of the receipt or accrual of such refund and increased by the amount of any Tax (but not in excess of the amount of such reduction) saved as a result of such payment or (ii) the amount the Sublessee or any of its insurers has paid in respect of such Claim; provided that, so long as a Sublease Event of Default shall have occurred and is continuing, such amount may be held by the Sublessor as security for the Sublessee’s obligations under the Facility Sublease Documents.

Section 20.6 Minimize Claims. The Sublessor and any other Sublessor Indemnitee will, to the extent within their control, use their respective reasonable efforts to minimize Claims relating to them, respectively, indemnifiable by the Sublessee under this Section 20, including by complying with reasonable requests by the Sublessee to do or to refrain from doing any act if such compliance is of a purely ministerial nature or, in the good faith opinion of the Sublessor, otherwise has no adverse impact on the Sublessor or any Affiliate of any thereof or on the business or operations of any of the foregoing.

Section 21.

GENERAL TAX INDEMNITY

Section 21.1 General Tax Indemnity.

(a) Indemnity.

(vi) Taxes imposed on any assignee or successor-in-interest to the Tax Indemnitee (including any transfer by merger, consolidation, liquidation, reorganization or otherwise by operation of law) to the extent any such Taxes exceed the Taxes that would have been imposed had no assignment or transfer taken place determined under the law as in effect on the date of the transfer; provided that this exclusion shall not apply for purposes of determining gross-up amounts and payments required to be made on an After-Tax Basis;

(vii) Taxes imposed on the Tax Indemnitee attributable to the Tax Indemnitee’s or any Related Party to such Tax Indemnitee’s being treated as other than a United States Person.

(viii) Taxes attributable to the failure of the Tax Indemnitee or any Related Party thereto to comply on a timely basis with certification, information, documentation, reporting or other similar requirements; provided that this exclusion shall only apply if such Tax Indemnitee or Related Party is eligible to comply with such requirement and shall have been given timely written notice of such requirement by the Sublessee;

(x) Taxes imposed on the Tax Indemnitee resulting from an amendment, modification, supplement or waiver to any Operative Document which was not requested by the Sublessee unless such amendment, modification, supplement or waiver (A) was required by Applicable Law or the Operative Documents, (B) is necessary or appropriate to conform with any amendment, modification, supplement or waiver to any Operative Document requested by the Sublessee in writing, or (C) is made while a Sublease Event of Default shall have occurred and be continuing;

(xi) Taxes relating to Section 4975 of the Code, Title I of ERISA or any Similar Law to the extent attributable to a breach by the Tax Indemnitee of its representations and/or covenants in Section 3.4(g) or 7.8 of the Participation Agreement, Section 6.8 or 7.2 of the OP Guaranty, Section 4.3 of the Certificate Purchase Agreement or the Certificates (including in respect of any beneficial interest therein), as applicable;

(xiv) Taxes imposed on the Sublessor or any Related Party thereto as a result of the Sublessor’s being treated as other than a disregarded entity or pass through entity for tax purposes;

provided, however, that no Tax that is being contested in good faith in an appropriate proceeding shall be payable (except as may be required to be paid pursuant to Section 21.1(c) below) while such proceeding is pending or subject to any appeal pending a final judgment.

(c) Payment. Each payment required to be made by the Sublessee to the Tax Indemnitee pursuant to this Section 21.1 shall be paid either (i) when due directly to the applicable taxing authority, by the Sublessee if it is permitted to do so, or (ii) where direct payment is not permitted and with respect to gross-up amounts, in immediately available funds to the Tax Indemnitee by the later of (A) 30 days following the Sublessee’s receipt of the Tax Indemnitee’s written demand for the payment (which demand shall be accompanied by a statement of the Tax Indemnitee describing in reasonable detail the Taxes for which the Tax Indemnitee is demanding indemnity and the computation of such Taxes), (B) subject to Section 21.1(g) below, in the case of amounts which are being contested pursuant to such Section 21.1(g), at the time and in accordance with a final determination of such contest or (c) in the case of any indemnity demand for which the Sublessee has requested review and determination pursuant to Section 21.1(d) below, the completion of such review and determination; provided, however, that in no event shall such payment (or, at the Sublessee’s option pursuant to Section 21.1(g)(iii)(E), payment by the Sublessee of a Tax Advance) be made later than the date which is five Business Days prior to the date on which such Taxes are required to be paid to the applicable taxing

authority. Any amount payable to the Sublessee pursuant to Section 21.1(e) or Section 21.1(f) below shall be paid promptly (but in all events within 30 days) after the Tax Indemnitee realizes a Tax or Indemnity Benefit giving rise to a payment under Section 21.1(e) or receives a refund or credit giving rise to a payment under Section 21.1(f) or receives a payment from a Head Lease Tax Indemnitee under Section 9.2(e) or (f) of the Participation Agreement, as the case may be, and shall be accompanied by a statement of the Tax Indemnitee computing in reasonable detail the amount of such payment. Any amount that would be payable to the Sublessee pursuant to Section 21.1(e) or Section 21.1(f) below but for the fact that such amount would be in excess of the amount of indemnity(ies) previously paid to the Tax Indemnitee by the Sublessee may be used as an offset against any future general tax indemnity payments owed by the Sublessee to the Tax Indemnitee. Upon the final determination of any contest pursuant to Section 21.1(g) below in respect of any Taxes for which the Sublessee has made a Tax Advance, the amount of the Sublessee’s obligation under Section 21.1(a) above shall be determined as if such Tax Advance had not been made. Any obligation of the Sublessee under this Section 21.1 and the Tax Indemnitee’s obligation to repay the Tax Advance will be satisfied first by set-off against each other, and any difference owing by either party will be paid within 10 days of such final determination.

upon the Sublessee and the Tax Indemnitee (absent manifest error). Such accounting firm shall be requested to makes its determination within 30 days.

(e) Tax or Indemnity Benefit. If, as the result of any Taxes paid or indemnified against by the Sublessee under this Section 21.1, (i) the aggregate Taxes actually paid by the Tax Indemnitee for any taxable year are less (whether by reason of a deduction, credit, allocation or apportionment of income or otherwise) than the amount of such Taxes that otherwise would have been payable by the Tax Indemnitee, or (ii) the Tax Indemnitee actually receives a payment pursuant to Section 9.2(e) of the Participation Agreement (each a “Tax or Indemnity Benefit”), then to the extent such Tax or Indemnity Benefit was not taken into account in determining the amount of indemnification payable under Section 21.1(a) above and provided no Sublease Event of Default shall have occurred and be continuing (in which event the payment provided under this Section 21.1(e) shall be deferred until the Sublease Event of Default has been cured), the Tax Indemnitee shall pay to the Sublessee the lesser of (A) (y) the amount of such Tax or Indemnity Benefit, plus (z) an amount equal to any United States federal, state or local income tax benefit realized by the Tax Indemnitee as a result of the payment under clause (y) above and this clause (z) and (B) the amount of the indemnity(ies) paid pursuant to this Section 21.1 giving rise to such Tax or Indemnity Benefit. If it is subsequently determined that the Tax Indemnitee was not entitled to such Tax or Indemnity Benefit, the portion of such Tax or Indemnity Benefit that was repaid to the Sublessee will be treated as Taxes for which the Sublessee must indemnify the Tax Indemnitee pursuant to this Section 21.1 without regard to Section 21.1(b) (other than Section 21.1(b)(iii)).

(f) Refund. If the Tax Indemnitee obtains a refund or credit of all or part of any Taxes paid, reimbursed or advanced by the Sublessee pursuant to this Section 21.1 or a payment from a Head Lease Tax Indemnitee under Section 9.2(f) of the Participation Agreement with respect to a refund or credit of any Taxes indemnified by the Sublessee, the Tax Indemnitee promptly shall pay to the Sublessee (x) the amount of such refund or credit (net of any Tax payable by the Tax Indemnitee or a Head Lease Tax Indemnitee as a result of the receipt or accrual of such refund or credit if the payment of such refund or credit by the Tax Indemnitee to the Sublessee or a Head Lease Tax Indemnitee to the Sublessor is not deductible against such Tax) plus (y) an amount equal to any United States federal, state or local income tax benefit realized by (i) such Tax Indemnitee as a result of the payments under clause (x) above and this clause (y) or (ii) the Head Lease Tax Indemnitee as a result of, and to the extent reflected in the calculation thereof, the payment by the Head Lease Tax Indemnitee under Section 9.2(f) of the Participation Agreement; provided that (A) if at the time such payment is due to the Sublessee a Sublease Event of Default shall have occurred and be continuing, such amount shall not be payable until such Sublease Event of Default has been cured, and (B) the amount payable to the Sublessee pursuant to this sentence shall not exceed the amount of the indemnity(ies) paid pursuant to Section 21.1 in respect of such refunded or credited Taxes. If it is subsequently determined that the Tax Indemnitee or a Head Lease Tax Indemnitee was not entitled to such refund or credit, the portion of such refund or credit that was repaid to the Sublessee will be treated as Taxes for which the Sublessee must indemnify the Tax Indemnitee pursuant to this Section 21.1 without regard to Section 21.1(b) (other than Section 21.1(b)(iii)). If, in connection with a refund or credit of all or party of any Taxes paid, reimbursed or advanced by the

Sublessee pursuant to this Section 21.1, the Tax Indemnitee receives an amount representing interest on such refund or credit, the Tax Indemnitee promptly shall pay to the Sublessee (1) the amount of such interest that shall be fairly attributable to such Taxes paid, reimbursed or advanced by the Sublessee prior to the receipt of such refund or credit (net of Taxes payable in respect of the receipt or accrual of such interest if the payment of such interest by the Head Lease Tax Indemnitee to the Tax Indemnitee or the Tax Indemnitee to the Sublessee is not deductible against such Tax) and (2) any Tax savings realized by the Head Lease Tax Indemnitee or Tax Indemnitee as a result of the payments made by the Head Lease Tax Indemnitee or Tax Indemnitee as described under (1) and (2).

(g) Contest. With respect to the exercise of rights by the Tax Indemnitee under Section 9.2(g) of the Participation Agreement, the Tax Indemnitee shall, to the extent permitted under Section 9.2(g) of the Participation Agreement, grant the Sublessee a power of attorney to act on behalf of the Tax Indemnitee, provided that no Sublease Event of Default shall have occurred and be occurring.

(i) Notice of Contest. If a written claim for payment is made by any taxing authority against the Tax Indemnitee or a Head Lease Tax Indemnitee for any Taxes with respect to which the Sublessee is liable for indemnity hereunder (a “Tax Claim”), the Tax Indemnitee shall give the Sublessee written notice of such Tax Claim promptly after its receipt (and in all events within 30 days of such receipt), and shall furnish the Sublessee with copies of such Tax Claim and all other writings received from the taxing authority to the extent relating to such Taxes; provided that failure so to notify the Sublessee shall not relieve the Sublessee of any obligation to indemnify the Tax Indemnitee hereunder except as provided in clause (xii) of Section 21.1(b). The Tax Indemnitee shall not pay, or permit a Head Lease Tax Indemnitee to pay, such Tax Claim or take any other action with respect to such Tax Claim without the written consent of the Sublessee until at least 30 days after providing the Sublessee with such written notice; provided, however, that if action shall be required by Applicable Law to be taken prior to the end of such 30-day period, the Tax Indemnitee shall, in its notice to the Sublessee, so inform the Sublessee, and the Tax Indemnitee shall not take, or permit a Head Lease Tax Indemnitee to take, any action with respect to such Tax Claim without the written consent of the Sublessee before such time as action shall be required by Applicable Law to be taken.

(ii) Control of Contest. Subject to Section 21.1(g)(iii) below, the Sublessee will be entitled to contest (acting through counsel selected by the Sublessee and reasonably satisfactory to the Tax Indemnitee), and control the contest of, any Tax Claim if (i) the contest of the Tax Claim can be pursued in the name of the Sublessee; (ii) the contest of such Tax Claim must be pursued in the name of the Tax Indemnitee but may in the reasonable judgment of the Tax Indemnitee be segregated procedurally from tax claims for which the Sublessee is

not obligated to indemnify the Tax Indemnitee (with the Tax Indemnitee agreeing or agreeing to use reasonable efforts to ensure that the Head Lease Tax Indemnitee will agree to use reasonable efforts to segregate the contest of any indemnified Tax from the contest of any unindemnified Tax, so that the Sublessee can control the contest of the indemnified Tax) or (iii) the Head Lease Tax Indemnitee or the Tax Indemnitee requests that the Sublessee control such contest. In the case of all other Tax Claims, subject to Section 21.1(g)(iii) below, the Tax Indemnitee will, or will use reasonable efforts to ensure that the Head Lease Tax Indemnitee will, in good faith diligently contest the Tax Claim (including seeking judicial review of any adverse administrative determination and appealing any adverse judicial determination, except that no appeal shall be required to the United States Supreme Court) if the Sublessee shall request that the Tax be contested, and the following rules shall apply with respect to such contest:

(A) the Tax Indemnitee will, or will use reasonable efforts to ensure that the Head Lease Tax Indemnitee will, control the contest of such Tax Claim in good faith (acting through counsel selected by the Tax Indemnitee and reasonably satisfactory to the Sublessee),

(B) at the Sublessee’s written request, if payment is made to the applicable taxing authority, the Tax Indemnitee shall, or shall use reasonable efforts to ensure that the Head Lease Tax Indemnitee shall, use all reasonable efforts to obtain a refund thereof in appropriate administrative or judicial proceedings, and

(C) the Tax Indemnitee shall, or shall use reasonable efforts to ensure that the Head Lease Tax Indemnitee shall, not otherwise settle, compromise or abandon such contest without the Sublessee’s prior written consent except as provided in Section 21.1(g)(iv).

In any case, the party conducting such contest shall consult in good faith with and keep reasonably informed the other party or parties and its designated counsel (and shall provide the other party or parties with copies of any documents, reports or claims issued by or sent to the relevant auditing agent or taxing authority as well as redacted portions of tax returns) with respect to such Tax Claim; provided, however¸ that the decisions regarding any actions to be taken shall be made by the party controlling the contest in its sole judgment.

(iii) Conditions of Contest. Not withstanding the foregoing, in no event shall the Sublessee be permitted to contest or continue to contest (or shall the Tax Indemnitee be required to contest or continue to contest) any Tax Claim pursuant to this Section 21.1, unless:

(A) within 30 days after notice by the Tax Indemnitee to the Sublessee of such Tax Claim (or such shorter period as is reasonably specified by the Tax Indemnitee if any contest of such Tax Claim must be commence prior to the expiration of such 30-day period), the Sublessee shall request in writing to the Tax Indemnitee that such Tax Claim be contested,

(B) no Sublease Event of Default has occurred and is occurring,

(C) there is no material risk of sale, forfeiture or loss of, or the creation of a material Lien on the Facility or any Component or portion thereof as a result of the contest of such Tax Claim (other than a Permitted Lien); provided that this clause (3) shall not apply if the Sublessee posts a bond or other security (which may include cash reserves) reasonably satisfactory to the Tax Indemnitee or the Taxes are fully paid in either manner specified in clause (5) below,

(D) there is no material risk of imposition of any criminal liability to the Tax Indemnitee as a result of the contest of such Tax Claim,

(E) if such contest involves payment of such Taxes, the Sublessee either advances to the Tax Indemnitee (on an interest-free basis and an After-Tax Basis) the amount of such payment (a “Tax Advance”) or pays the Tax Indemnitee (on an After-Tax Basis) the amount payable by the Sublessee pursuant to Section 21.1(a) above with respect to such Taxes,

(F) the Sublessee agrees to pay and shall pay on demand and on an After-Tax Basis all reasonable out-of-pocket costs and expenses that the Tax Indemnitee may incur in connection with the contest of such Tax Claim (including all reasonable legal, accounting and investigatory fees and disbursements),

(G) the amount of the Taxes in controversy, taking into account the amount of all similar and logically related Taxes with respect to the transactions contemplated by the Operative Documents and the Facility Sublease Documents that could be raised in any other year (including any future year) not barred by the statute of limitations, exceeds $25,000, and

(H) the Tax Indemnitee has been provided with an opinion of independent tax counsel selected by the Sublessee and reasonably

acceptable to the Tax Indemnitee to the effect that there is a Reasonable Basis for contesting such Tax Claim.

(iv) Waiver of Indemnification. Notwithstanding anything to the contrary contained in this Section 21.1, the Tax Indemnitee at any time may elect to decline to take any action or any further action with respect to a Tax Claim and may in its sole discretion settle or compromise any contest with respect to such Tax Claim without the Sublessee’s consent (and the Tax Indemnitee must so act to the extent that the Head Lease Tax Indemnitee has so acted) if the Tax Indemnitee:

(A) waives its right to any indemnity payment by the Sublessee in respect of such Tax Claim (and any other claim for Taxes with respect to any other taxable year the contest of which is effectively precluded by the Tax Indemnitee’s declining to take action with respect to the Tax Claim), and

(B) promptly pays to the Sublessee an amount which, after addition or subtraction of any further net decrease or increase, respectively, of Taxes realized by the Tax Indemnitee as a result of (i) such payment or (ii) the receipt by the Tax Indemnitee of any payment from a Head Lease Tax Indemnitee under the comparable provision of Section 9.2(g) of the Participation Agreement and the payment thereof by the Tax Indemnitee to the Sublessee, shall be equal to the amount of any Tax Advance and any payments made to the Tax Indemnitee under Section 21.1(a) above in respect of such Tax Claim, provided, however, that the amount of such repayment shall not include the amount of any costs or expenses with respect to any such contest.

Except as provided in the preceding sentence, any such waiver shall be without prejudice to the rights of the Tax Indemnitee with respect to any other Tax Claim.

(h) Reports.

(i) If any report, statement or return is required to be filed by the Tax Indemnitee or a Head Lease Tax Indemnitee with respect to any Tax that is subject to indemnification under this Section 21.1, the Sublessee shall (1) notify the Tax Indemnitee in writing of such requirement not later than 30

(ii) The Tax Indemnitee and the Sublessee will timely provide the other, at the Sublessee’s expense, with all information in its possession that the other party may reasonably require and request to satisfy its obligations under this Section 21.1(h). The Sublessee shall indemnify and hold the Tax Indemnitee harmless on an After-Tax Basis from and against all liabilities, costs and expenses (including the attorneys’, accountants’ and other professional fees for tax related filings or reviews) of the Tax Indemnitee arising out of any insufficiency or inaccuracy of any report, statement or return if such insufficiency or inaccuracy results from the insufficiency or inaccuracy of any information to be supplied by the Sublessee pursuant to this Section 21.1(h) in preparing and filing such report, statement or return.

In the event that any payment to the Guaranty Beneficiary in respect of the Obligations is rescinded or must otherwise be returned for any reason whatsoever, each of the Guarantors shall remain liable hereunder with respect to the Obligations as if such payment had not been made. This Guaranty is an absolute, unlimited, continuing and unconditional guarantee of performance and payment (but not of collection) of the Obligations. The liability of each Guarantor under this Guaranty shall, to the fullest extent permitted under applicable law, be absolute, irrevocable and unconditional. This Guaranty is a primary and original obligation of each Guarantor and is not merely the creation of a surety relationship. The obligations of each Guarantor set forth herein constitute the full recourse obligations of such Guarantor enforceable against it to the full extent of all its assets and properties. Without limiting the foregoing, it is agreed and understood that (a) repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, any Guaranteed Party shall be in default with respect to the Obligations under the terms of the Facility Sublease Documents or the Operative Documents, and (b) notwithstanding the recovery hereunder for or in respect of any given default with respect to the Obligations of any Guaranteed Party under any Facility Sublease Document or any Operative Document, this Guaranty shall remain in full force and effect and shall apply to each and every subsequent default with respect to the Obligations.

3. CHANGES IN OBLIGATIONS. Each Guarantor agrees that the Guaranty Beneficiary may at any time and from time to time, without notice to or further consent of either Guarantor, extend the time of payment or performance of any Obligations, and may also make any agreement with the Guaranteed Party or with any other Person interested in the transactions contemplated by the Facility Sublease Documents for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any Facility Sublease Document or any Operative Document without in any way impairing or affecting the Guarantors' obligations under this Guaranty. The obligations of each Guarantor hereunder shall not be subject to any counterclaim, setoff, deduction or defense (other than payment or performance) based upon any claim or defense such Guarantor may have against the Guaranty Beneficiary or any claim or defense such Guarantor may have against any Guaranteed Party or any other Person and shall remain in full force and effect without regard to, and shall not be released, discharged, reduced or in any way affected by, any circumstance or condition whatsoever (whether or not either Guarantor shall have any knowledge or notice thereof) which might constitute a legal or equitable discharge or defense including, but not limited to:

(i) any amendment, modification, supplement or termination (by operation of law or otherwise), express or implied, of any Facility Sublease Document or Operative Document, or any other instrument applicable to any Guaranteed Party or to such Guaranteed Party’s Obligations, or any part thereof;

(ii) any failure on the part of any Guaranteed Party to perform or comply with any term of any Facility Sublease Document or Operative Document;

(iii) any waiver, consent, change, extension, indulgence or other action or any action or inaction under or in respect of any Facility Sublease Document or Operative Document, including this Guaranty, whether or not the Guaranty Beneficiary, any Guaranteed Party or either Guarantor has notice or knowledge of any of the foregoing;

(iv) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or similar proceeding with respect to the Guaranty Beneficiary, either Guarantor or any Guaranteed Party, or their respective properties or their creditors, or any action taken by any trustee or receiver or by any court in any such proceeding;

(v) any furnishing or acceptance of additional security or any release of any security (and each Guarantor authorizes the Guaranty Beneficiary to furnish, accept or release said security);

(vi) any termination (by operation of law or otherwise), cancellation (by operation of law or otherwise), frustration or unenforceability, in whole or in part, of any Facility Sublease Document or Operative Document or any term thereof;

(vii) any Lien on or affecting the respective assets and properties of either Guarantor or any Guaranteed Party;

(viii) any claim as a result of any other dealings among the Guaranty Beneficiary, either Guarantor, or any of them;

(ix) any change in the name of the Guaranty Beneficiary, any Guaranteed Party or any other Person;

(x) any redelivery, repossession, sale, transfer or other disposition or surrender of the Facility, the Ground Interest or any part thereof;

(xi) the transfer, assignment, mortgaging or purported transfer, assignment or mortgaging of all or any part of the interest of any Guaranteed Party in the

Facility, the Ground Interest, any part thereof or any Facility Sublease Document or Operative Documents;

(xii) any failure of title with respect to the interest of any Guaranteed Party, or its successors and assigns, in the Facility, the Ground Interest or any part thereof;

(xiii) any merger or consolidation of any Guaranteed Party or either Guarantor into or with any other Person or any direct or indirect sale, lease or transfer of any other assets of any Guaranteed Party or either Guarantor to any other Person;

(xiv) any change in the ownership of any shares of capital stock of either Guarantor or any Guaranteed Party (including any such change which results in either Guarantor no longer owning capital stock of any Guaranteed Party); or

(xv) any termination of the Facility Lease or the Facility Sublease as a result of the rejection thereof or other action by any Guaranteed Party or any trustee, receiver or liquidating agent of the Guaranteed Party or any of its properties in any bankruptcy, insolvency, reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar proceeding (whether or not the Sublessee remains in possession of the Facility).

4. CERTAIN WAIVERS. To the fullest extent permitted by Law, each of the Guarantors hereby expressly and unconditionally waives: (a) notice of any of the matters referred to in Section 3 hereof; (b) all notices which may be required by statute, rule of law or otherwise (except as expressly required to be given to the Guarantors by any Facility Sublease Document) to preserve any rights against the Guarantors hereunder, including notice of the acceptance of this Guaranty by the Guaranty Beneficiary, or the creation, renewal, extension, modification or accrual of the Obligations or notice of any other matters relating thereto, any presentment, demand, notice of dishonor, protest or nonpayment of any damages or other amounts payable under any Facility Sublease Document or any Operative Document; (c) any requirement for the enforcement, assertion or exercise of any right, remedy, power or privilege under or in respect of any Facility Sublease Document or any Operative Document, including diligence in collection or protection of or realization upon or in respect of the Obligations or any part thereof; (d) any requirement of diligence; (e) the occurrence of every other condition precedent to which such Guarantor or any Guaranty Beneficiary may otherwise be entitled, except as provided in any Facility Sublease Document or any Operative Document; (f) any requirement to mitigate the damages resulting from a default or termination under any Facility Sublease Document or any Operative Document, except that this shall not relieve the Guaranty Beneficiary of any such obligation; and (g) the right to require the Guaranty Beneficiary to proceed against any Guaranteed Party or any other Person liable on the Obligations, to proceed against or exhaust security held from any Guaranteed Party or any other Person, or to pursue any other remedy in

the Guaranty Beneficiary’s power whatsoever, and each Guarantor waives the right to have the property of any Guaranteed Party first applied to the discharge of the Obligations.

The Guaranty Beneficiary may, at its election, exercise any right or remedy it might have against any Guaranteed Party or any security held by the Guaranty Beneficiary, including the right to foreclose upon any such security by judicial or nonjudicial sale, without affecting or impairing in any way the liability of either Guarantor hereunder, except to the extent the Obligations have been paid or satisfied, and each Guarantor waives any defense arising out of the absence, impairment or loss of any right of reimbursement, contribution or any other right or remedy of such Guarantor against any Guaranteed Party or any such security, whether resulting from such election by the Guaranty Beneficiary, or otherwise.

Each Guarantor assumes the responsibility for being and keeping informed of the financial condition of each Guaranteed Party and of all other circumstances bearing upon the risk of nonpayment or nonperformance of the Obligations and agrees that the Guaranty Beneficiary shall not have any duty to advise any Guarantor of information regarding any condition or circumstance or any change in such condition or circumstance. Each Guarantor acknowledges that the Guaranty Beneficiary has not made any representation to the Guarantor concerning the financial condition of the Guaranteed Parties.

5. NO WAIVER; CUMULATIVE RIGHTS. No failure on the part of the Guaranty Beneficiary to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Guaranty Beneficiary of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power hereunder. Each and every right, remedy and power hereby granted to the Guaranty Beneficiary or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Guaranty Beneficiary at any time or from time to time.

6. REPRESENTATIONS AND WARRANTIES. Each Guarantor hereby represents and warrants that:

(e) all Governmental Approvals (if any) which are required as of the date hereof for the execution, delivery or performance by the Guarantor of its obligations under this Guaranty have been obtained or made, were validly issued, are not the subject of any pending request for rehearing or appeal, and are in full force and effect (other than any Governmental Approvals, the failure to obtain which is not likely to cause a Material Adverse Effect);

EXHIBIT D

GUARANTY

GUARANTY, dated as of [ ], 2008 (this “Guaranty”), from National Grid Plc, a public limited company organized under the laws of England and Wales, and National Grid USA, a Delaware corporation (each a “Guarantor,” and together the “Guarantors”), in favor of KeySpan-Ravenswood, LLC, a New York limited liability company (the “Guaranty Beneficiary”).

18. GUARANTY. In order to induce the Guaranty Beneficiary to enter into a certain Facility Sublease, dated as of [], 2008 (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Facility Sublease”; unless the context hereof shall otherwise require, capitalized terms used in this Guaranty and not otherwise defined herein shall have the respective meanings specified therefor in the Facility Sublease) by and between [UNIT 40 SUBLESSOR], as sublessor (in such capacity, the “Sublessor”) and KeySpan-Ravenswood, LLC, as sublessee (in such capacity, the “Sublessee”), together with other Facility Sublease Documents (as such term is defined in the Facility Sublease) and to consummate the transactions contemplated therein with the Sublessee, each Guarantor, jointly and severally, hereby absolutely, unconditionally and irrevocably guarantees to the Guaranty Beneficiary the due, punctual and full payment (when and as the same may become due and payable, at the stated due date, by acceleration or otherwise) of each amount that the Guaranteed Party is obligated to pay under or pursuant to Section 2.2(b), Section 4.2(b) and Section 10.3 of the Facility Sublease (the “Obligations”), in each case, without regard to whether such Obligation is direct or indirect, absolute or contingent, now or hereafter existing or owing, voluntary or involuntary, created or arising by contract, operation of law or otherwise or incurred or payable before or after commencement of any proceedings by or against any Guaranteed Party under any bankruptcy law. In furtherance of the foregoing, each of the Guarantors acknowledges that the Guaranty Beneficiary may, in its sole discretion, bring and prosecute a separate action or actions against either Guarantor in respect of any or all of the Obligations, regardless of whether action is brought against the Guaranteed Party or whether the Guaranteed Party is joined in any such action or actions. The Obligations of each Guarantor under this Guaranty are joint and several. As used in this Guaranty, the “Guaranteed Party” shall mean the Sublessor.

19. NATURE OF GUARANTY. This Guaranty is in no way conditioned upon any attempt to collect from any Guaranteed Party or upon any other event or contingency, and shall be binding upon and enforceable against each Guarantor without regard to the validity, regularity or enforceability of any Facility Sublease Document, any Operative Document or of any term thereof. In the event that any payment to the Guaranty Beneficiary in respect of the Obligations is rescinded or must otherwise be returned for any reason whatsoever, each Guarantor shall remain liable hereunder with respect to the Obligations as if such payment had not been made. This Guaranty is an absolute, unlimited, continuing and unconditional guarantee of performance and payment (but not of collection) of the Obligations. The liability of each Guarantor under this Guaranty shall, to the fullest extent permitted under applicable law, be absolute, irrevocable and unconditional. This Guaranty is a primary and original obligation of each Guarantor and is not merely the creation of a surety relationship. The obligations of each Guarantor set forth herein constitute the full recourse obligations of each Guarantor enforceable against it to the full extent of all its assets and properties. Without limiting the foregoing, it is agreed and understood that (a) repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, any Guaranteed Party shall be in default with respect to the Obligations

under the terms of the Facility Sublease or the Operative Documents, and (b) notwithstanding the recovery hereunder for or in respect of any given default with respect to the Obligations of any Guaranteed Party under any Facility Sublease Document or any Operative Document, this Guaranty shall remain in full force and effect and shall apply to each and every subsequent default with respect to the Obligations.

20. CHANGES IN OBLIGATIONS. Each Guarantor agrees that the Guaranty Beneficiary may at any time and from time to time, without notice to or further consent of either Guarantor, extend the time of payment or performance of any Obligations, and may also make any agreement with the Guaranteed Party or with any other Person interested in the transactions contemplated by the Facility Sublease Documents for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between the Guaranteed Party and the Guaranty Beneficiary without in any way impairing or affecting the Guarantors' obligations under this Guaranty. The obligations of each Guarantor hereunder shall not be subject to any counterclaim, setoff, deduction or defense (other than payment or performance) based upon any claim or defense such Guarantor may have against the Guaranty Beneficiary or any claim or defense such Guarantor may have against the Guaranteed Party or any other Person and shall remain in full force and effect without regard to, and shall not be released, discharged, reduced or in any way affected by, any circumstance or condition whatsoever (whether or not either Guarantor shall have any knowledge or notice thereof) which might constitute a legal or equitable discharge or defense including, but not limited to:

(xvi) any amendment, modification, supplement or termination (by operation of law or otherwise), express or implied, of any Facility Sublease Document or Operative Document, or any other instrument applicable to the Guaranteed Party or to such Guaranteed Party’s Obligations, or any part thereof;

(xvii) any failure on the part of the Guaranteed Party to perform or comply with any term of any Facility Sublease Document or Operative Document;

(xviii) any waiver, consent, change, extension, indulgence or other action or any action or inaction under or in respect of any Facility Sublease Document or Operative Document, including this Guaranty, whether or not the Guaranty Beneficiary, the Guaranteed Party or either Guarantor has notice or knowledge of any of the foregoing;

(xix) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or similar proceeding with respect to the Guaranty Beneficiary, either Guarantor or the Guaranteed Party, or their respective properties or their creditors, or any action taken by any trustee or receiver or by any court in any such proceeding;

(xx) any furnishing or acceptance of additional security or any release of any security (and each Guarantor authorizes the Guaranty Beneficiary to furnish, accept or release said security);

(xxi) any termination (by operation of law or otherwise), cancellation (by operation of law or otherwise), frustration or unenforceability, in whole or in part, of any Facility Sublease Document or Operative Document or any term thereof;

(xxii) any Lien on or affecting the respective assets and properties of either Guarantor or the Guaranteed Party;

(xxiii) any claim as a result of any other dealings among the Guaranty Beneficiary, either Guarantor, or any of them;

(xxiv) any change in the name of the Guaranty Beneficiary, the Guaranteed Party or any other Person;

(xxv) any redelivery, repossession, sale, transfer or other disposition or surrender of the Facility, the Ground Interest or any part thereof;

(xxvi) the transfer, assignment, mortgaging or purported transfer, assignment or mortgaging of all or any part of the interest of the Guaranteed Party in the Facility, the Ground Interest, any part thereof or any Facility Sublease Document or Operative Documents;

(xxvii) any failure of title with respect to the interest of any Guaranteed Party, or its successors and assigns, in the Facility, the Ground Interest or any part thereof;

(xxviii) any merger or consolidation of any Guaranteed Party or either Guarantor into or with any other Person or any direct or indirect sale, lease or transfer of any other assets of the Guaranteed Party or either Guarantor to any other Person;

(xxix) any change in the ownership of any shares of capital stock of either Guarantor or the Guaranteed Party (including any such change which results in either Guarantor no longer owning capital stock of the Guaranteed Party); or

(xxx) any termination of the Facility Lease or the Facility Sublease as a result of the rejection thereof or other action by the Guaranteed Party or any trustee, receiver or liquidating agent of the Guaranteed Party or any of its properties in any bankruptcy, insolvency, reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar proceeding (whether or not the Sublessee remains in possession of the Facility).

21. CERTAIN WAIVERS. To the fullest extent permitted by Law, each Guarantor hereby expressly and unconditionally waives: (a) notice of any of the matters referred to in Section 3 hereof; (b) all notices which may be required by statute, rule of law or otherwise (except as expressly required to be given to the Guarantors by any Facility Sublease Document) to preserve any rights against the Guarantors hereunder, including notice of the acceptance of this Guaranty by the Guaranty Beneficiary, or the creation, renewal, extension, modification or accrual of the Obligations or notice of any other matters relating thereto, any presentment, demand, notice of dishonor, protest or nonpayment of any damages or other amounts payable under any Facility Sublease Document or any Operative Document; (c) any requirement for the enforcement, assertion or exercise of any right, remedy, power or privilege under or in respect of any Facility Sublease Document or any Operative Document, including diligence in collection or protection of or realization upon or in respect of the Obligations or any part thereof; (d) any requirement of diligence; (e) the occurrence of every other condition precedent to which such Guarantor or any Guaranty Beneficiary may otherwise be entitled, except as provided in any Facility Sublease Document or any Operative Document; (f) any requirement to mitigate the damages resulting from a default or termination under any Facility Sublease Document or any Operative Document, except that this shall not relieve the Guaranty Beneficiary of any such obligation; and (g) the right to require the Guaranty Beneficiary to proceed against the Guaranteed Party or any other Person liable on the Obligations, to proceed against or exhaust security held from any Guaranteed Party or any other Person, or to pursue any other remedy in the Guaranty Beneficiary’s power whatsoever, and each Guarantor waives the right to have the property of the Guaranteed Party first applied to the discharge of the Obligations.

The Guaranty Beneficiary may, at its election, exercise any right or remedy it might have against the Guaranteed Party or any security held by the Guaranty Beneficiary, including the right to foreclose upon any such security by judicial or nonjudicial sale, without affecting or impairing in any way the liability of either Guarantor hereunder, except to the extent the Obligations have been paid or satisfied, and each Guarantor waives any defense arising out of the absence, impairment or loss of any right of reimbursement, contribution or any other right or remedy of such Guarantor against the Guaranteed Party or any such security, whether resulting from such election by the Guaranty Beneficiary, or otherwise.

Each Guarantor assumes the responsibility for being and keeping informed of the financial condition of the Guaranteed Party and of all other circumstances bearing upon the risk of nonpayment or nonperformance of the Obligations and agrees that the Guaranty Beneficiary shall not have any duty to advise any Guarantor of information regarding any condition or circumstance or any change in such condition or circumstance. Each Guarantor acknowledges that the Guaranty Beneficiary has not made any representation to the Guarantor concerning the financial condition of the Guaranteed Party.

22. NO WAIVER; CUMULATIVE RIGHTS. No failure on the part of the Guaranty Beneficiary to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Guaranty Beneficiary of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power hereunder. Each and every right, remedy and power hereby granted to the Guaranty Beneficiary or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Guaranty Beneficiary at any time or from time to time.
