The Owner Participant Commitment set forth in this Section 2.3(b) shall expire on the Commitment Termination Date (after the Advance to be made on the Lease Commencement Date pursuant to Section 4.3(a)(ii) and, if required, Section 4.4), without further action on the part of the Owner Participant.

(c) Funding Requests: Notice of Borrowing. Whenever the Company desires that the Owner Lessor request an Advance of funds for use and application in accordance with the Operative Documents, the Company shall submit a Funding Request (each, a “Funding Request”) to the Owner Lessor, the Indenture Trustee and the Owner Participant at least eight (8) Business Days prior to the date on which the Company requires a distribution of funds (the “Requested Funding Date”), or in the case of the initial Advance of funds on the Construction Closing Date, at least three (3) Business Days in advance of such date, providing the information required to be provided by Section 3.2 with respect to such Advance. Each Funding Request shall (i) be signed by an Authorized Officer of the Company and (ii) be substantially in the form of Exhibit O. No more than two Advances under Section 2.2 and this Section 2.3 may be drawn in any calendar month and no more than eighteen (18) Advances under Section 2.2 and this Section 2.3 may be drawn in any calendar year. Each Funding Request given by the Company in accordance with this Section 2.3(c) shall be deemed to have been given jointly by the Owner Lessor and the Company.

(d) Disbursement of Advances. If the conditions precedent to an Advance as set forth in this Section 2.3 and in Section 3.2 shall have been satisfied or waived by the Owner Participant, then no later than 12:00 Noon, New York City time, on each Requested Funding Date, (i) an amount equal to the Debt Funding Amount requested by the Company on such Requested Funding Date shall be withdrawn from the Note Proceeds Account and distributed in

accordance with Section 3.5(a) of the Disbursement Agreement and (ii) the Owner Participant shall wire transfer an amount, in Dollars and in immediately available funds, equal to the Equity Funding Amount requested by the Company on such Requested Funding Date to the Equity Proceeds Account, which amount shall be withdrawn from the Equity Proceeds Account and distributed in accordance with Section 3.5(a) of the Disbursement Agreement. Notwithstanding anything to the contrary set forth in the Operative Documents, it is agreed that, other than with respect to the Advance to be made on the Construction Closing Date, the Owner Participant may waive the non-satisfaction of any of the conditions set forth in Section 3.2 and, so long as the Owner Participant shall have deposited into the Equity Proceeds Account an amount equal to the Equity Funding Amount requested by the Company to be made on such Requested Funding Date pursuant to the requirements set forth in this Section 2.3, proceeds on deposit in the Note Proceeds Account in an amount equal to the Debt Funding Amount requested to be funded by the Company on such Requested Funding Date shall be withdrawn from the Note Proceeds Account and distributed in accordance with Section 3.5(a) of the Disbursement Agreement concurrently with the funding by the Owner Participant, unless an Indenture Event of Default shall have occurred and is continuing on such date and the Initial Lessor Notes shall have been accelerated.

Section 2.4 Owner Participant Authorization. The Owner Participant hereby authorizes and directs the Owner Lessor to issue the Initial Lessor Notes to the Pass Through Trustees as provided in this Article II.

Section 2.5 Equity Commitment Fee. The Owner Lessor shall pay to the Owner Participant, and the Owner Participant shall pay to the Equity Investor, from the proceeds of Advances made by the Owner Participant, a nonrefundable fee (the “Equity Commitment Fee”) equal to ¾ of 1% per annum on the average daily amount of the unused portion of the Owner Participant Commitment. The Equity Commitment Fee shall accrue daily from the Construction Closing Date until the Commitment Termination Date and is payable monthly in arrears on the last day of each month and on the Commitment Termination Date.

Section 2.6 Making of Equity Contributions. The Equity Contributions made by the Owner Participant from time to time may be (i) LIBOR Rate Equity Contributions, (ii) Base Rate Equity Contributions or (iii) a combination thereof, as determined by the Company and notified to the Owner Participant pursuant to Sections 2.3(c) and 2.8.

Section 2.7 Certain Agreements Regarding Yield Periods. (a) Each of the Owner Lessor and the Owner Participant hereby agrees that, notwithstanding anything to the contrary contained in this Agreement, the Indenture or any other Operative Documents, without the prior written consent of the Company (which consent shall not be required during the occurrence and continuance of a Significant Company Default or a Company Event of Default), the Owner Lessor shall not take any action with respect to the Equity Contributions concerning the (a) continuation of a LIBOR Rate Equity Contribution as a LIBOR Rate Equity Contribution or (b) conversion of a LIBOR Rate Equity Contribution to a Base Rate Equity Contribution or a Base Rate Equity Contribution to a LIBOR Rate Equity Contribution. The Owner Lessor hereby appoints and authorizes the Company to act as its exclusive agent (and agrees that it will not act other than through the Company, as such agent) for the purpose of (i) continuing a LIBOR Rate Equity Contribution as a LIBOR Rate Equity Contribution or (ii) converting a LIBOR Rate Equity Contribution to a Base Rate Equity Contribution or a Base Rate Equity Contribution to a

LIBOR Rate Equity Contribution; provided, that such appointment and authorization shall not confer upon the Company during any period in which a Significant Company Default or a Company Event of Default shall have occurred and be continuing, the authority to act as agent to designate an Equity Contribution as other than a Base Rate Equity Contribution. Each of the Owner Lessor and the Owner Participant hereby consents to such appointment and authorization. In taking any actions as agent of the Owner Lessor as aforesaid, the Company shall be authorized to deal directly with the Owner Participant and each of the Owner Lessor and the Owner Participant agrees to cooperate with the Company and otherwise to do all things and take all actions reasonably necessary to effect the actions taken by the Company as the agent of the Owner Lessor under this Section 2.7.

(b) Any action taken by Owner Lessor in violation of any of the foregoing shall be null and void and of no force and effect.

Section 2.8 Conversion and Continuation Options. (a) The Company may elect from time to time to convert all or a portion of the LIBOR Rate Equity Contributions to Base Rate Equity Contributions by giving the Owner Participant prior irrevocable notice of such election no later than 11:00 A.M., New York City time, on the Business Day preceding the proposed conversion date; provided, that any such conversion of LIBOR Rate Equity Contributions may only be made on the last day of a Yield Period with respect thereto. The Company may elect from time to time to convert all or a portion of the Base Rate Equity Contributions to LIBOR Rate Equity Contributions by giving the Owner Participant prior irrevocable notice of such election no later than 11:00 A.M., New York City time, on the third Business Day preceding the proposed conversion date (which notice shall specify the length of the initial Yield Period therefor). All or any part of the outstanding LIBOR Rate Equity Contributions or Base Rate Equity Contributions may be converted as provided herein; provided, that no Base Rate Equity Contributions may be converted into LIBOR Rate Equity Contributions when any Significant Company Default or Company Event of Default has occurred and is continuing and the Owner Participant has determined in its sole discretion not to permit such conversions after the date that is one month prior to the Commitment Termination Date.

(b) Any LIBOR Rate Equity Contribution may be continued as such upon the expiration of the then current Yield Period with respect thereto by the Company giving irrevocable notice to the Owner Participant, in accordance with the applicable provisions of the term “Yield Period” set forth in Appendix A hereto, of the length of the next Yield Period to be applicable to such Equity Contribution, provided, that no LIBOR Rate Equity Contribution may be continued as such when any Significant Company Default or Company Event of Default has occurred and is continuing and the Owner Participant has determined in its sole discretion not to permit such continuation, and provided, further, that if the Company shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Equity Contribution shall be automatically continued as a LIBOR Rate Equity Contribution on the last day of such then expiring Yield Period and such continued LIBOR Rate Equity Contribution shall have a Yield Period with the same length as that of then expiring Yield Period.

Section 2.9 Limitations on LIBOR Rate Tranches. Notwithstanding anything to the contrary in this Agreement or the other Operative Documents, all Advances, conversions

and continuations of LIBOR Rate Equity Contributions and all selections of Yield Periods shall be in such amounts and be made pursuant to such elections so that, no more than five LIBOR Rate Tranches shall be outstanding at any one time, collectively in respect of LIBOR Rate Equity Contributions.

Section 2.10 Equity Yield and Payment Dates. (a) Each LIBOR Rate Equity Contribution shall bear Equity Yield for each day during each Yield Period with respect thereto at a rate per annum determined in accordance with clause (i) of the definition of “Equity Yield” in Appendix A.

(b) Each Base Rate Equity Contribution shall bear Equity Yield at a rate per annum determined in accordance with clause (ii) of the definition of “Equity Yield” in Appendix A.

(c) If all or a portion of (i) any Equity Contribution, (ii) any Equity Yield payable on any Equity Contribution, (iii) any Equity Commitment Fee or (iv) any other amount calculated with respect thereto, shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear Equity Yield at a rate per annum equal to 200 basis points over the Base Rate then in effect, plus the Applicable Margin, from the date of such non-payment until such amount is paid in full (as well after as before judgment).

(d) Equity Yield shall be payable in arrears on each Yield Payment Date from the proceeds of Advances made by the Owner Participant, provided that Equity Yield accruing pursuant to paragraph (c) of this Section 2.10 shall be payable from time to time on demand and provided, further that each prepayment of Equity Contributions shall be accompanied by accrued Equity Yield to the date of such prepayment.

Section 2.11 Computation of Interest, Equity Yield and Fees. (a) Equity Yield and Equity Commitment Fees payable pursuant to this Agreement shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to Base Rate Equity Contributions, the Equity Yield on which is calculated on the basis of the Prime Rate, the Equity Yield thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Owner Participant shall as soon as practicable notify the Company of each determination of a LIBOR Rate in respect thereof. Any change in the rate of Equity Yield on an Equity Contribution resulting from a change in the Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Owner Participant shall as soon as practicable notify the Company of the effective date and the amount of each such change in the rate of Equity Yield on an Equity Contribution.

(b) Each determination of the rate of Equity Yield on an Equity Contribution by the Owner Participant pursuant to any provision of this Agreement shall be conclusive and binding on the Company in the absence of manifest error. The Owner Participant shall, at the request of the Company, deliver to the Company and the Owner Lessor a statement showing the quotations used by the Owner Participant in determining any rate of Equity Yield on an Equity Contribution pursuant to Section 2.10(a).

Section 2.12 Inability to Determine Rate on Equity Yield. If, prior to the first day of any Yield Period, the Owner Participant shall have determined (which determination shall be conclusive and binding upon the Company) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the LIBOR Rate for such Yield Period, the Owner Participant shall give telecopy or telephonic notice thereof to the Owner Lessor and the Company as soon as practicable thereafter. If such notice is given (x) any LIBOR Rate Equity Contributions requested to be made on the first day of such Yield Period shall be made as Base Rate Equity Contributions, (y) any Equity Contribution that was to have been converted on the first day of such Yield Period to a LIBOR Rate Equity Contribution shall be continued as a Base Rate Equity Contribution and (z) any outstanding LIBOR Rate Equity Contributions shall be converted, on the last day of the then-current Yield Period, to Base Rate Equity Contributions. Until the Owner Participant has withdrawn such notice, no further LIBOR Rate Equity Contributions shall be made or continued as such, nor shall the Company have the right to convert such Base Rate Equity Contributions to LIBOR Rate Equity Contributions.

Section 2.13 Payments. All payments to be made by the Owner Lessor hereunder, whether on account of Equity Yield, Equity Commitment Fees or otherwise, shall be made without setoff or counterclaim from the proceeds of Advances made by the Owner Participant and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Owner Participant, in Dollars and in immediately available funds. If any payment hereunder (other than payments on the LIBOR Rate Equity Contributions) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a LIBOR Rate Equity Contribution becomes due and payable on a day other than a LIBOR Business Day, the maturity thereof shall be extended to the next succeeding LIBOR Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding LIBOR Business Day.

Section 2.14 Requirements of Law. (a) If a Change in Law:

(i) shall subject the Owner Participant or any Consolidated Tax Group Member to any tax of any kind whatsoever with respect to this Agreement or any LIBOR Rate Equity Contribution made by it, or change the basis of taxation of payments to the Owner Participant in respect thereof (except for Taxes covered by Section 12.2(k) and changes in the rate of tax on the overall net income of the Owner Participant or any Consolidated Tax Group Member);

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of the Owner Participant or any Consolidated Tax Group Member that is not otherwise included in the determination of the LIBOR Rate; or

(iii) shall impose on the Owner Participant or any Consolidated Tax Group Member any other condition relating to the making or maintaining of LIBOR Rate Equity Contributions;

and the result of any of the foregoing is to increase the cost to the Owner Participant or any Consolidated Tax Group Member, by an amount that the Owner Participant or any Consolidated Tax Group Member deems to be material, of making, converting into, continuing or maintaining LIBOR Rate Equity Contributions, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Company shall promptly pay to the Owner Participant, on an After-Tax Basis, any additional amounts necessary to compensate the Owner Participant or any Consolidated Tax Group Member for such increased cost or reduced amount receivable. If the Owner Participant or any Consolidated Tax Group Member becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Company of the event by reason of which it has become so entitled.

(b) If the Owner Participant shall have determined that the adoption of or any change in any Applicable Law regarding capital adequacy or in the interpretation or application thereof or compliance by the Owner Participant or any Person controlling the Owner Participant with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on the Owner Participant’s or such Person’s capital as a consequence of its obligations hereunder to a level below that which the Owner Participant or such Person could have achieved but for such adoption, change or compliance (taking into consideration the Owner Participant’s or such Person’s policies with respect to capital adequacy) by an amount deemed by the Owner Participant to be material, then from time to time, after submission by the Owner Participant to the Company of a written request therefor, the Company shall pay to the Owner Participant such additional amount or amounts as will compensate the Owner Participant or such Person for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this Section 2.14 submitted by the Owner Participant to the Company shall be conclusive in the absence of manifest error. Notwithstanding anything to the contrary in this Section 2.14, the Company shall not be required to compensate the Owner Participant pursuant to this Section 2.14 for any amounts incurred more than nine months prior to the date that the Owner Participant notifies the Company of the Owner Participant’s intention to claim compensation therefor; provided, that, if the circumstances giving rise to such claim have a retroactive effect, then such nine-month period shall be extended to include the period of such retroactive effect. The obligations of the Company pursuant to this Section 2.14 shall survive the termination of this Agreement and the payment of the Equity Contributions and all other amounts payable hereunder.

Section 2.15 Indemnity. The Company agrees to indemnify the Owner Participant for, and to hold the Owner Participant harmless from, any loss or expense that the Owner Participant or any Consolidated Tax Group Member may sustain or incur as a consequence of (a) a default by the Company in requesting the Owner Lessor to request an Advance of, conversion into or continuation of a LIBOR Rate Equity Contribution after the Company has given a notice to the Owner Lessor in order to request the same in accordance with the provisions of this Agreement, (b) a default by the Company in making any prepayment of or conversion from a LIBOR Rate Equity Contribution after the Company has requested that the Owner Lessor give a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of a LIBOR Rate Equity Contribution on a day that is not the last

day of a Yield Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of Equity Yield that would have accrued on the amount so prepaid, or not so advanced, converted or continued, for the period from the date of such prepayment or of such failure to advance, convert or continue to the last day of such Yield Period (or, in the case of a failure to advance, convert or continue, the Yield Period that would have commenced on the date of such failure), in each case, at the applicable rate of Equity Yield for such Equity Contributions provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of Equity Yield (as reasonably determined by the Owner Participant) that would have accrued to the Owner Participant on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank LIBOR market. A certificate as to any amounts payable pursuant to this Section 2.15 submitted to the Company by the Owner Participant shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Equity Contributions and all other amounts payable hereunder.

Section 2.16 Closing Date. The closing of the Overall Transaction (the “Construction Closing”) shall take place after 9:00 A.M., New York City time, on the Scheduled Closing Date or such other date as the parties hereto shall mutually agree (the “Construction Closing Date”), at the offices of Simpson Thacher & Bartlett LLP in New York City.

Section 2.17 Transaction Expenses; Fees and Expenses; Make-Whole Premium. (a) All Transaction Expenses incurred on or prior to the Construction Closing Date and substantiated by an appropriate invoice or otherwise supported in reasonable detail shall be paid by the Owner Lessor from the proceeds of Advances. Subject to Section 2.17(b) and the Mandate Letter, all other fees, costs and expenses incurred by the Funding Parties on or prior to the Construction Closing Date shall be for their respective accounts whether or not the Overall Transaction is consummated.

(b) On the Construction Closing Date, all administration fees through the end of the Facility Lease Term charged by the Trust Company, the Independent Manager, the Pass Through Trustees, the Indenture Trustee and the Depositary Bank shall be paid by the Owner Lessor from the proceeds of Advances.

(c) On and after the Lease Commencement Date, Make-Whole Premium shall be payable by the Company to the Noteholders, if and when due, as Supplemental Lease Rent.

(d) All Transaction Expenses due and payable on the Lease Commencement Date by any Funding Party and substantiated by an appropriate invoice or otherwise supported in reasonable detail and which are in excess of the Transaction Expenses used in the Pricing Assumptions shall be paid directly by the Company. Any such payment shall not result in an adjustment to Basic Lease Rent.

Section 2.18 Limit on the Company’s Obligations. Notwithstanding anything to the contrary in any Operative Document or the Certificate Purchase Agreement, recourse of the Company in respect of any payment of its obligations under the Operative Documents or the Certificate Purchase Agreement made prior to the Lease Commencement Date or otherwise in respect of Project Costs made prior to the Lease Commencement Date shall be limited to the

proceeds of Advances, Other Available Amounts and amounts payable by Persons that the Company is required to pay over to the Owner Lessor, any Noteholder, the Indenture Trustee, the Depository Bank, the Initial Purchaser or the Pass Through Trustees, except that (i) any payment obligation (other than any Non-Recourse Payment Obligation) pursuant to Article XII, Section 7 of the Certificate Purchase Agreement and Section 4.1(f) of the Disbursement Agreement shall not be paid with the proceeds of Advances or Other Available Amounts, but shall be paid directly by the Company with other funds of the Company, (ii) the Company shall be personally liable with respect to the exercise of remedies pursuant to Section 11.4 upon the occurrence of a Company Event of Default and, with respect to the payment of any obligation (other than any Non-Recourse Payment Obligation), pursuant to Article XII, Section 7 of the Certificate Purchase Agreement and Section 4.1(f) of the Disbursement Agreement, but in any such case, only to the extent provided in Section 11.5 and (iii) the Company shall be personally liable for all of its obligations under the Operative Documents or otherwise in respect of Project Costs if the Company delivers a Recourse Notification pursuant to Section 3.1 of the Construction Agency Agreement (and, no recourse limitations under the Operative Documents shall thereafter apply in any respect).

Section 2.19 Mandatory Prepayments of Lessor Notes; Mandatory Reduction of Owner Participant Commitment. (a) If, at any time prior to the Lease Commencement Date, the Company shall have received notice from the Unit 4 Owner of the Unit 4 Owner’s intention to exercise its option to make a lump sum payment (i) to the Owner Lessor to purchase an undivided ownership interest in all, but not a portion, of the Designated Shared Facilities (as defined in the Shared Facilities Agreement) pursuant to Section 4.1.4(b) of the Shared Facilities Agreement and/or (ii) to reimburse the Owner Lessor for 50% of the Existing Station Construction Work Sum (as defined in the Existing Facilities Upgrade Reimbursement Agreement) pursuant to Section 3.2.2 of the Existing Facilities Upgrade Reimbursement Agreement (such options, the “Unit 4 Owner Options”), the Company shall promptly notify the Owner Lessor, the Owner Participant and the Indenture Trustee of the exercise of either or both of such options. Such notice from the Company to the Owner Lessor, the Owner Participant and the Indenture Trustee shall specify (A) the Unit 4 Owner Option Base Amount expected to be received from the Unit 4 Owner upon the exercise of either or both of the Unit 4 Owner Options, (B) the amount of funds expected to be received from the Unit 4 Owner upon the exercise of either or both of the Unit 4 Owner Options in respect of Make-Whole Premium, Breakage Costs and Swap Termination Obligation and any other amounts due to the Secured Parties (other than accrued interest on the Lessor Notes) (the “Unit 4 Owner Option Other Amount”, and together with the Unit 4 Owner Option Base Amount, the “Unit 4 Owner Option Purchase Amount”) and (C) the date of expected receipt of the Unit 4 Owner Option Purchase Amount, which date shall not be later than 5 Business Days prior to the Lease Commencement Date. Upon the Owner Lessor’s receipt of the Unit 4 Owner Option Purchase Amount, the Owner Lessor shall promptly pay over such amount to the Indenture Trustee.

(b) The Indenture Trustee shall distribute the Unit 4 Owner Option Base Amount to the Noteholders and the Owner Participant pro rata in accordance with the Debt/Equity Ratio in existence immediately prior to the receipt of such amount. The portion of the Unit 4 Owner Option Base Amount paid to the Indenture Trustee for distribution to the Noteholders pursuant to the preceding sentence shall be used to prepay the Lessor Notes, together with accrued interest to the date of such prepayment on the amount of Lessor Notes so

prepaid, in the manner set forth in Section 3.5(d)(iii) of the Indenture. The portion of the Unit 4 Owner Option Base Amount paid to the Owner Participant pursuant to the first sentence of this Section 2.19(b) shall be used to prepay any outstanding Equity Contributions advanced by the Owner Participant to the Owner Lessor, together with accrued Equity Yield to the date of such prepayment on the amount of Equity Contributions so prepaid. Once prepaid pursuant to this Section 2.19(b), such Equity Contributions may not be re-advanced pursuant to Section 2.3 and the Owner Participant Commitment shall be permanently reduced by the amount of such prepayment.

(c) The Indenture Trustee shall distribute the Unit 4 Owner Option Other Amount to the Noteholders in amounts sufficient to cover any Make-Whole Premium and any other amounts due and payable on the Lessor Notes (other than accrued interest), to the Owner Participant in amounts sufficient to cover any Breakage Costs due and payable on any LIBOR Rate Equity Contribution and to the Swap Counterparty in amounts sufficient to cover any Swap Termination Obligations due and payable under the Swap Agreement, in each such case, to the extent such amounts have become due and payable due to the exercise of either or both of the Unit 4 Owner Options and the related prepayment of the Lessor Notes and Equity Contributions.

(d) The parties agree that all or a portion of the Unit 4 Owner Option Base Amount may be paid by the Unit 4 Owner on a date prior to the date specified for prepayment of the Lessor Notes in the notice of prepayment given pursuant to Section 3.6 of the Indenture. In such event, the parties agree that the amount of such early payment by the Unit 4 Owner may be held by the Company, in trust for the sole benefit of the Owner Lessor, and that the amount of such payment held by the Company shall be required to be paid over to the Owner Lessor immediately prior to the date specified for prepayment of the Lessor Notes in the notice of prepayment given pursuant to Section 3.6 of the Indenture. In no event shall any portion of the Unit 4 Owner Option Base Amount held by the Company be considered to be the Property of the Company, but shall at all times be and remain the Property of the Owner Lessor until paid over to the Indenture Trustee.

(A) (1) in connection with an event described in clause (i) above, a legal opinion to the effect that the risk of bankruptcy consolidation of the Transferee with the Transferee’s parent immediately after giving effect to the transfer of such equity interest is not materially greater than the risk of bankruptcy consolidation of the transferor with such transferor’s parent, immediately prior to giving effect to such transfer or (2) in connection with an event described in clause (ii) above, a legal opinion to the effect that the risk of bankruptcy consolidation of the Owner Participant with the transferee in such transfer after giving effect to the transfer of such equity interest is not materially greater than the risk of bankruptcy consolidation of the Owner Participant with the transferor, immediately prior to giving effect to such transfer; and

(B) in connection with an event described in clause (i) above, an Officer’s Certificate of the Transferee certifying that the Constitutive Documents of the Transferee contain, and will continue to contain after the transfer, provisions substantially equivalent to those contained in the Constitutive Documents of the Owner Participant on the Construction Closing Date with respect to the following provisions: separateness, independent managers, no bankruptcy petition, no dissolution and amendment of such organizational documents or such other provisions as may be acceptable to the Rating Agencies.

The Notice of Construction Purchase shall specify the proposed date of purchase, which date shall in any event be no later than the date that is 90 days after the Notice of Construction Purchase is issued. The delivery of the Notice of Construction Purchase shall be deemed to constitute a Recourse Notification pursuant to Section 3.1 of the Construction Agency Agreement.

(b) Construction Period Remedies. Prior to the Lease Commencement Date, but subject to the provisions of the last sentence of this Section 11.4(b). the Owner Lessor may exercise any of the following remedies at the Owner Lessor’s option and without limiting the Owner Lessor in the exercise of any other right or remedy the Owner Lessor may have on account of such default, including, subject to Section 11.5, any remedies under any other Operative Document:

(i) If a Company Event of Default shall have occurred and be continuing, then the Owner Lessor may, in addition to the other rights and remedies provided for in this Article XI, immediately terminate the Construction Agency Agreement in whole or in part by giving the Company written notice of such termination, and, upon the giving of such notice, all rights of the Company and all obligations of the Owner Lessor under the Construction Agency Agreement with respect to the portion of the Construction Agency Agreement being so terminated shall cease.

(ii) If a Company Event of Default constituting a Full Recourse Event shall have occurred and be continuing, the Owner Lessor may require the Company to pay the Construction Balance, and upon payment in full of the Construction Balance, the Owner Lessor shall comply with the provisions of Section 11.7.

(iii) If a Company Event of Default constituting a Partial Recourse Event shall have occurred and be continuing the Owner Lessor may require the Company to pay to the Owner Lessor the Partial Recourse Amount and may require the Company to relinquish promptly all of its right, title and interest in, to and under the Facility, the Ground Interest and the Project Document Interest to the Owner Lessor in accordance with the provisions of Section 11.8. Simultaneously therewith or at any time thereafter, at the request of the Owner Lessor, the Company shall use commercially reasonable efforts to sell the Facility, the Ground Interest and the Project Document Interest on an “arm’s length” basis at the Fair Market Sales Value for cash and the sales proceeds of any such sale shall be applied in accordance with Section 4.2(b) of the Indenture.

(iv) If one or more Company Events of Default constituting Non-Recourse Events shall have occurred and be continuing and no Full Recourse Event or Partial Recourse Event shall have occurred and be continuing the Owner Lessor may require the Company to relinquish promptly all of its right, title and interest in, to and under the Facility, the Ground Interest and the Project Document Interest to the Owner Lessor in accordance with the provisions of Section 11.8.

In the event the Company delivers a Notice of Construction Purchase in accordance with Section 11.4(a), the Owner Lessor may not exercise any remedy under this Section 11.4(b) to the extent such exercise would prevent the Company from being able to consummate its purchase obligation on the date designated in such Notice of Construction Purchase (it being understood

and agreed the foregoing shall not constitute any further limitation on the exercise of remedies if the Company fails to pay the Construction Balance in full by the date specified in such Notice of Construction Purchase).

Section 11.5 Recourse Limitations. (a) Notwithstanding any other provision of the Operative Documents, if a Full Recourse Event shall have occurred and the Owner Lessor exercises any of the remedies set forth in Section 11.4, the Company’s aggregate recourse liability on account of the exercise of such remedies shall not be limited in any respect.

(b) Notwithstanding any other provision of the Operative Documents, if a Company Event of Default constituting a Partial Recourse Event shall have occurred, no Full Recourse Event shall have occurred and the Owner Lessor exercises any of the remedies set forth in Section 11.4, the Company’s aggregate recourse liability on account of the exercise of such remedies by the Owner Lessor under this Agreement and the other Operative Documents shall be limited to the Partial Recourse Amount, together with interest thereon at the Overdue Rate from the date any such amounts were due until the date of payment, so long as the Company has complied with its obligations in Section 11.8 within ten (10) Business Days of demand by the Owner Lessor.

(d) Upon the occurrence and continuance of a Company Event of Default, any Participant may elect to fund any Project Cost or otherwise attempt to achieve the Completion Date or to fund any other costs or expenses (whether pursuant to Section 2.3(c) or otherwise) and such payment or funding shall be deemed an Advance by the Owner Lessor on the date so advanced and shall be deemed to increase the amount owed under the Operative Documents by the Owner Lessor to each Participant by the amount so funded, and the Construction Balance shall, on such date, be increased by the aggregate amounts so advanced.

(e) On and after the Lease Commencement Date, upon the occurrence and continuance of a Company Event of Default, the remedies, powers and privileges provided in Section 16 of the Facility Lease, and not in this Article XI (other than in Section 11.9 or 11.10) shall apply, together with any other remedies, powers and privileges provided in the other Operative Documents.

provided that the terms “omission”, “negligence”, “gross negligence” and “willful misconduct”, when applied with respect to the Independent Manager, the Trust Company, the Owner Participant, the Owner Lessor, the Depositary Bank, the Indenture Trustee, the Pass Through Trustees or any Affiliate of any thereof, shall not include any liability imputed as a matter of law to such Indemnitee solely by reason of any such entity’s interest in the Facility or the Site or any such Indemnitee’s failure to act in respect of matters which are or were the obligation of the Company under this Agreement or any other Transaction Document.

(c) Insured Claims. Subject to the provisions of paragraph (e) of this Section 12.1, in the case of any Claim indemnified by the Company hereunder which is covered by a policy of insurance maintained by the Company, each Indemnitee agrees, unless it and each other Indemnitee shall waive its rights to indemnification (for itself and each Related Party thereto) in a manner reasonably acceptable to the Company, to cooperate, at the sole cost and expense of the Company, with insurers in exercise of their rights to investigate, defend or compromise such Claim; provided, that, so long as a Company Event of Default shall have occurred and be continuing, an Indemnitee may request evidence from the Company that any cost or expense relating to such cooperation will be paid by the Company promptly upon incurrence.

(d) After-Tax Basis. The Company agrees that any payment or indemnity pursuant to this Section 12.1 in respect of any Claim shall be made on an After-Tax Basis to the Indemnitees.

(e) Claims Procedure. Each Indemnitee shall promptly after such Indemnitee shall have Actual Knowledge thereof notify the Company in writing of any Claim as to which indemnification is sought; provided, that the failure so to notify the Company shall not reduce or affect the Company’s liability that it may have to such Indemnitee under this Section 12.1 unless such failure materially increases the Company’s liability under such claim from that which would have existed if the failure to give notice had not occurred and the Indemnitee knew or should have known of such consequences of its failure to provide notice. Any amount payable to any Indemnitee pursuant to this Section 12.1 shall be paid within 15 Business Days after receipt of such written demand therefor from such Indemnitee (or, if the Facility Lease is terminated pursuant to Section 10, 13, 14 or 16 thereof prior to the expiration of the 15 Business Day period, by such date of termination), accompanied by an Officer’s Certificate of such Indemnitee stating in reasonable detail the basis for the indemnification thereby sought and, if such Indemnitee is not a party hereto, an agreement to be bound by the terms of this Section 12.1, as if such

Indemnitee were such a party. The foregoing shall not, however, constitute an obligation to disclose confidential information of any kind without the execution of an appropriate confidentiality agreement. Promptly after the Company receives notification of such Claim accompanied by a written statement describing in reasonable detail the Claims that are the subject of and basis for such indemnity and the computation of the amount so payable, the Company shall notify such Indemnitee in writing whether it intends to pay, object to, compromise or defend any matter involving the asserted liability of such Indemnitee. The Company shall have the right to investigate and, so long as no Significant Company Default or Company Event of Default shall have occurred and be continuing, the Company shall have the right, in its sole discretion, to defend or compromise any Claim for which indemnification is sought under this Section 12.1 that the Company acknowledges is subject to indemnification hereunder; provided, that no such defense or compromise (i) is reasonably likely to involve any danger of foreclosure, sale, forfeiture or loss of, or imposition of a Lien on any part of the Facility, the Site, the Lessor Estate or the impairment of the Facility in any material respect, (ii) is reasonably likely to involve any danger or a material adverse effect on the interests of any Indemnitee or (iii) could result in any criminal liability being incurred by, or could reasonably be expected to have any material adverse effect on, such Indemnitee, provided, further, that no Claim shall be compromised by the Company on a basis that admits any criminal violation or gross negligence or willful misconduct on the part of such Indemnitee without the express written consent of such Indemnitee; and provided, further, that, to the extent that other Claims unrelated to the transactions contemplated by the Operative Documents are part of the same proceeding involving such Claim, the Company may assume responsibility for the contest or compromise of such Claim only if the same may be and is severed from such other Claims (and each Indemnitee agrees to use reasonable efforts to obtain such a severance). If the Company elects, subject to the foregoing, to compromise or defend any such asserted liability, it may do so at its own expense and by counsel selected by it and reasonably satisfactory to such Indemnitee. Upon the Company’s election to compromise or defend such asserted liability and prompt notification to such Indemnitee of its intent to do so, such Indemnitee shall cooperate at the Company’s expense with all reasonable requests of the Company in connection therewith and will provide the Company, at the Company’s expense, with all information not within the control of the Company as is reasonably available to such Indemnitee that the Company may reasonably request; provided, however, that such Indemnitee shall not, unless otherwise required by Applicable Law, be obligated to disclose to the Company or any other Person, or permit the Company or any other Person to examine (i) any income tax returns of the Owner Participant, the Owner Lessor, the OP Guarantor or the Equity Investor or (ii) any confidential information or pricing information not generally accessible by the public possessed by the Owner Participant, the Owner Lessor, the OP Guarantor or the Equity Investor (and, in the event that any such information is made available, the Company shall treat such information as confidential and shall take all actions reasonably requested by such Indemnitee for purposes of obtaining a stipulation from all parties to the related proceeding providing for the confidential treatment of such information from all such parties). Where the Company, or the insurers under a policy of insurance maintained by the Company, undertake the defense of such Indemnitee with respect to a Claim (with counsel reasonably satisfactory to such Indemnitee), no additional legal fees or expenses of such Indemnitee in connection with the defense of such Claim shall be indemnified hereunder unless such fees or expenses were incurred at the request of the Company or such insurers. Notwithstanding the foregoing, an Indemnitee may participate at its own expense in

any judicial proceeding controlled by the Company pursuant to the preceding provisions, but only to the extent that such Person’s participation does not in the reasonable opinion of counsel of the Company interfere with such control; provided, however, that such party’s participation does not constitute a waiver of the indemnification provided in this Section 12.1; provided, further, that if and to the extent that (i) such Indemnitee is advised by counsel that an actual or potential conflict of interest exists where it is advisable for such Indemnitee to be represented by separate counsel or (ii) there is a risk that such Indemnitee may be indicted or otherwise charged in a criminal complaint and such Indemnitee informs the Company that such Indemnitee desires to be represented by separate counsel, such 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 bome by the Company. So long as no Company Event of Default shall have occurred and be continuing, no Indemnitee shall enter into any settlement or other compromise with respect to any Claim without the prior written consent of the Company unless (i) the Indemnitee waives its rights to indemnification hereunder or (ii) the Company has not acknowledged its indemnity obligation with respect thereto and there is a significant risk that a default judgment will be entered against such Indemnitee. Nothing contained in this Section 12.1(e) shall be deemed to require an Indemnitee to contest any Claim or to assume responsibility for or control of any judicial proceeding with respect thereto.

(f) Subrogation. To the extent that a Claim indemnified by the Company under this Section 12.1 is in fact paid in full by the Company or an insurer under an insurance policy maintained by the Company, the Company (so long as no Company Event of Default shall have occurred and be continuing) or such insurer shall be subrogated to the rights and remedies of the Indemnitee on whose behalf such Claim was paid to the extent of such payment (other than rights of such Indemnitee under insurance policies maintained at its own expense or rights of the Independent Manager under the LLC Agreement) with respect to the transaction or event giving rise to such Claim. Should an Indemnitee receive any refund, in whole or in part, with respect to any Claim paid by the Company hereunder, it shall promptly pay over to the Company 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 Company or any of its insurers has paid in respect of such Claim; provided, that, so long as a Significant Company Default or a Company Event of Default shall have occurred and is continuing, such amount may be held by the Owner Lessor as security for the Company’s obligations under the Facility Lease and the other Operative Documents.

(g) Construction Period. To the extent any Claim asserted prior to the Lease Commencement Date would be indemnifiable under Section 12.1(a) but relates to any act, omission, event or circumstance occurring with respect to the Facility, the Company shall not be obligated, prior to the Lease Commencement Date, to indemnify (i) any Person other than the Owner Lessor pursuant to Section 12.1(a) for such Claim or (ii) the Owner Lessor for any Claim that is a third party damage claim unless attributable to an act or omission by a Construction Agency Person (it being understood and agreed that the foregoing provisions of this sentence shall not limit the Company’s obligation pursuant to Section 12.1(a) to indemnify the Owner Lessor for any Claim resulting from the Owner Lessor’s obligations pursuant to the next sentence, but shall be subject to the recourse limitations set forth in Section 2.18, to the extent

applicable). Subject to the provisions of Section 12.3, the Owner Lessor shall indemnify and keep harmless each Indemnitee from any Claim that would be indemnifiable by the Company pursuant to Section 12.1(a) but for the provisions of the preceding sentence.

(h) Third Parties. Any Person seeking indemnity under this Section 12.1 who is not a party to this Agreement shall agree to the terms and conditions set forth in this Section 12.1 with respect to the applicable Claim as a condition to making any such claim for indemnity under this Section 12.1.

Section 12.2 General Tax Indemnity.

(a) Taxes Indemnified. Except as provided in Section 12.2(b) and Section 12.2(i), the Company shall, on an After-Tax Basis, indemnify (but, in all events, without duplication of indemnities) each of the other Funding Parties, Wilmington Trust Company (in its individual capacity), the Certificateholders and each such Person’s respective successors, assigns, agents, servants, shareholders, members, partners, directors, officers, employees and the Affiliates of each and all of the foregoing (each a “Tax Indemnitee”) for, hold each such Tax Indemnitee harmless from, and defend each such Tax Indemnitee against, the net amount (after giving effect to any countervailing credits, deductions and other reductions) of all Taxes imposed upon any such Tax Indemnitee, the Facility or the Site, or any portion or component thereof or any interest therein, or upon any Transaction Document or interest therein, arising out of, in connection with or relating to, any of the following:

(xii) Taxes imposed on or withheld from payments made to any Tax Indemnitee attributable to the Tax Indemnitee being treated as other than a U.S. Person (as defined in section 7701(a)(30) of the Code), except to the extent such determination is attributable to a change in law;

(xiii) Taxes attributable to the failure of a Tax Indemnitee to comply on a timely basis with certification, information, documentation, reporting or other similar requirements concerning the taxation, nationality, residence, identity, connection with the jurisdiction imposing such Taxes or other similar matters; provided, that the foregoing exclusion shall only apply if such Tax Indemnitee is eligible to comply with such

requirement and (other than with respect to the provision of a W-8BEN, W-8ECI, W-8IMY or W-9 form) shall have been given timely written notice of such requirement by the Company and the Tax Indemnitee shall have determined in good faith that compliance with any such requirement shall not result in any material adverse effect to it or its Affiliate’s interests (where such certification, information, documentation, reporting or similar requirement is not otherwise required to be made by the Tax Indemnitee under applicable law), unless the Tax Indemnitee shall have been indemnified by the Company against such consequences in a manner which is reasonably satisfactory to the Tax Indemnitee;

(xiv) Taxes imposed on a Tax Indemnitee where the Tax Indemnitee’s breach of its contest obligations effectively precludes the Company’s ability to contest the Tax;

(xv) Taxes imposed on any Tax Indemnitee resulting from an amendment to any Operative Document that was not requested by the Company and as to which the Company is not a party and the Tax Indemnitee (or, in the case of the Owner Participant, the Owner Lessor, if acting at the express direction of the Owner Participant) is a party unless such amendment (i) was required by Applicable Law or the Operative Documents, (ii) is necessary to conform with any amendment to any Operative Document requested by the Company in writing or (iii) is made during the continuance of a Company Event of Default;

(xvi) Taxes imposed under Section 4975 of the Code or under Subtitle B of Title I of ERISA on a particular Tax Indemnitee as a result of a breach of representation or covenant given by such Indemnitee under Section 6.4(h), 6.5 or 9.10 with respect to the source of funds used to provide the Lessor Notes or the Equity Contributions, as applicable;

(xvii) Taxes imposed or collected under Sections 1441 through 1446 of the Code;

(xviii) Taxes in the nature of an intangible or similar tax imposed on a leasehold property interest;

(c) Payment. Each payment required to be made by the Company to a Tax Indemnitee pursuant to this Section 12.2 shall be paid either (i) when due directly to the applicable taxing authority, by the Company 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 such Tax Indemnitee by the later of (A) 15 days following the Company’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 12.2(g) below, in the case of amounts that are being contested pursuant to such Section 12.2(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 Company has requested review and determination pursuant to Section 12.2(d) below, the completion of such review and determination; provided, however, in no event later than the date that is five Business Days prior to the date on which such Taxes are required to be paid to the applicable taxing authority (but subject to the Company’s option under Section 12.2(g)(iii)(E) hereof). Any amount payable to the Company pursuant to Section 12.2(e) or Section 12.2(f) below shall be paid within 15 days after the Tax Indemnitee realizes a Tax Benefit giving rise to a payment under Section 12.2(e) or receives a refund or credit giving rise to a payment under Section 12.2(f), 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 Company pursuant to Section 12.2(e) or Section 12.2(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 Company may be used as an offset against any future general tax indemnity payments owed by the Company to such Tax Indemnitee. Upon the final determination of any contest pursuant to Section 12.2(g) below in respect of any Taxes for which the Company has made a Tax Advance, the amount of the Company’s obligation under Section 12.2(a) above shall be determined as if such Tax Advance had not been made. Any obligation of the Company under this Section 12.2 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. All payments required to be made by the Company pursuant to this Section 12.2 shall be made on an After-Tax Basis.

(d) Independent Examination. Within 15 days after the Company receives any computation from a Tax Indemnitee, the Company may request in writing that an independent public accounting firm jointly selected by the Tax Indemnitee and the Company review and determine on a confidential basis the amount of any indemnity payment owed by the Company to the Tax Indemnitee pursuant to this Section 12.2 (and/or the amount of any reverse payment owed by the Tax Indemnitee to the Company pursuant to Section 12.2(e) or Section 12.2(f) below). The Tax Indemnitee shall cooperate with such accounting firm and supply it with all information reasonably necessary for the accounting firm to conduct such review and determination; provided, that (i) such accounting firm shall agree in writing in a manner reasonably satisfactory to the Tax Indemnitee to maintain the confidentiality of such information and (ii) neither any Tax Indemnitee nor the Company shall be required to disclose any of its tax returns or books that such Tax Indemnitee or the Company, as the case may be, reasonably deems to be confidential in connection with such verification. The parties hereto agree that each Tax Indemnitee shall have sole control over the positions taken with respect to its own tax returns and filings. The parties hereto further agree that the independent public accounting firm’s sole responsibility shall be to verify the computation of any payment pursuant to this Section 12.2 and that matters of interpretation of this Agreement or any other Operative Document are not within the scope of the independent accountant’s responsibility. The fees and disbursements of the accounting firm will be paid for by the Company, unless the verification results in an adjustment in the Company’s favor of the lesser of (i) $100,000 and (ii) five percent or more of the present value of the aggregate indemnity payment or payments computed by the Tax Indemnitee (determined using a discount rate of six percent), in which case the fees and disbursements will be paid for by the Tax Indemnitee. In the event the accounting firm determines that the Tax Indemnitee’s computations are incorrect, then such firm shall determine what it believes to be the correct computations. The computations of the accounting firm shall be final, binding and conclusive upon the Company and the Tax Indemnitee (absent manifest error). Such accounting firm shall be requested to make its determination within 30 days.

(e) Tax Benefit. If, as the result of any Taxes paid or indemnified against by the Company under this Section 12.2, the aggregate Taxes actually paid by the Tax Indemnitee in connection with such payment 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 such Tax Indemnitee (a “Tax Benefit”), then to the extent such Tax Benefit was not taken into account in determining the amount of indemnification payable under Section 12.2(a) above and provided no Significant Company Default or Company Event of Default shall have occurred and be continuing (in which event the payment provided under this Section 12.2(e) shall be deferred until the Significant Company Default or Company Event of Default has been cured), such Tax Indemnitee shall pay to the Company the lesser of (A) (y) the amount of such Tax Benefit plus (z) an amount equal to any United States federal, state or local income tax benefit realized by such Tax Indemnitee as a result of the payment under clause (y) above and this clause (z) (determined using the same assumptions as set forth in the second sentence under the definition of After-Tax Basis) and (B) the amount of the indemnity(ies) paid pursuant to this Section 12.2 giving rise to such Tax Benefit; provided, that any excess of the amount described in clause (A) over the amount described in clause (B) shall be carried forward and applied to reduce pro tanto any subsequent obligations of the Company to make payment to such Tax Indemnitee pursuant to this Section 12.2. If it is subsequently determined that the Tax Indemnitee was not entitled to such Tax Benefit, the portion of such Tax

Benefit that is required to be repaid or recaptured will be treated as Taxes for which the Company must indemnify the Tax Indemnitee pursuant to this Section 12.2 without regard to Section 12.2(b) (other than Section 12.2(b)(iii)).

(f) Tax Refund. If a Tax Indemnitee obtains a refund or credit of all or part of any Taxes paid, reimbursed or advanced by the Company pursuant to this Section 12.2, the Tax Indemnitee promptly shall pay to the Company the lesser of (A)(x) the amount of such refund or credit (net of any Tax payable by the 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 Company is not deductible against such Tax) plus (y) an amount equal to any United States federal, state or local income tax benefit realized by such Tax Indemnitee as a result of the payments to the Company under clause (x) above and this clause (y) (determined using the same assumptions as set forth in the second sentence under the definition of After-Tax Basis) and (B) the amount of the indemnity(ies) paid pursuant to this Section 12.2 in respect of such refunded or credited Taxes; provided, that any excess of the amount described in clause (A) over the amount described in clause (B) shall be carried forward and applied to reduce pro tanto any subsequent obligations of the Company to make payment to such Tax Indemnitee pursuant to this Section 12.2; and provided, further, that if at the time such payment is due to the Company a Significant Company Default or Company Event of Default shall have occurred and be continuing, such amount shall not be payable until such Significant Company Default or Company Event of Default has been cured. If it is subsequently determined that the Tax Indemnitee was not entitled to such refund or credit, the portion of such refund or credit that is required to be repaid or recaptured will be treated as Taxes for which the Company must indemnify the Tax Indemnitee pursuant to this Section 12.2 without regard to Section 12.2(b) (other than Section 12.2(b)(iii)). If, in connection with a refund or credit of all or part of any Taxes paid, reimbursed or advanced by the Company pursuant to this Section 12.2, a Tax Indemnitee receives an amount representing interest on such refund or credit, the Tax Indemnitee promptly shall pay to the Company the amount of such interest that shall be fairly attributable to such Taxes paid, reimbursed or advanced by the Company 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 Tax Indemnitee to the Company is not deductible against such Tax).

(g) Contests.

(i) Notice of Contest. If written claim for payment is made by any taxing authority against a Tax Indemnitee for Taxes with respect to which the Company may be liable for payment of indemnity hereunder (a “Tax Claim”), the Tax Indemnitee shall be required to provide written notice to the Company of such Tax Claim as soon as practicable (but in no event more than 10 days after receipt of such claim) after receipt and shall furnish the Company with copies of such Tax Claim and all other writings received from the demanding jurisdiction with respect to such Taxes; provided, however, that any failure to so notify the Company shall not alter the Tax Indemnitee’s rights except to the extent that such failure materially adversely affects the Company’s ability to conduct a contest of the indemnified Taxes. The Company shall be entitled for a period of 30 days from the receipt of such notice (or such shorter period as is reasonably specified by the Tax Indemnitee if any contest of the Taxes must be commenced prior to the expiration of 30 days) to request in writing that such Tax Indemnitee contest the

imposition of such Taxes at the Company’s sole cost and expense and the Tax Indemnitee shall not pay such Taxes within this period.

(ii) Control of Contest. Subject to Section 12.2(g)(iii) below, the Company will be entitled to contest (acting through counsel selected by the Company and reasonably satisfactory to the Tax Indemnitee), and control the contest of, any Tax Claim if (x) such contest can be pursued in the name of the Company, (y) such contest must be pursued in the name of such Tax Indemnitee, but can be pursued independently from any other proceeding involving a tax liability of such Tax Indemnitee (with each Tax Indemnitee agreeing to use all reasonable efforts to sever the contest of any indemnified Tax from the contest of any unindemnified Tax, so that the Company can control the contest of the indemnified Tax) or (z) such Tax Indemnitee requests that the Company control such contest; provided, that any control of a contest described in clauses (x) and (y) is subject to the condition that the Tax Indemnitee in its reasonable judgment determines that permitting the Company to conduct or continue to conduct such contest will not adversely impact other Taxes of such Tax Indemnitee (and if the Tax Indemnitee determines at any time that there will be an adverse impact on other Taxes of the Tax Indemnitee, then the Tax Indemnitee shall control, or regain control, of such contest). With respect to all other Tax Claims requested to be contested by the Company, subject to Section 12.2(g)(iii) below, the Tax Indemnitee shall contest such claim, including seeking judicial review of any adverse administrative determination and appealing any adverse judicial determination, and the Tax Indemnitee shall control the contest of the claim in good faith (acting through counsel selected by the Tax Indemnitee and reasonably acceptable to the Company).

(iii) In either case, the party conducting such contest shall consult in good faith with and keep reasonably informed the other party and its designated counsel (and shall provide the other party 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, but the decisions regarding what actions to be taken shall be made by the controlling party in its sole judgment; provided, however, that if the Tax Indemnitee is the controlling party, the Tax Indemnitee may not settle the Tax Claim without the consent of the Company, which consent may not be unreasonably withheld. All contests shall be at the Company’s sole cost and expense with no after tax cost to the Tax Indemnitee.

(iv) Conditions of Contest. Notwithstanding the foregoing, in no event shall the Company be permitted to contest (or shall the Tax Indemnitee be required to contest) any Tax Claim (A) if the contest of such Tax Claim involves a material risk of sale, forfeiture or loss of, or the creation of any material Lien (other than a Permitted Lien) on the Facility or any portion or Component thereof unless the Company has adequate reserves or shall have posted and maintained a bond or other security satisfactory to the relevant Tax Indemnitee or the Taxes shall have been paid in either manner specified in clause (E) below, (B) if a Significant Company Default or a Company Event of Default has occurred and is continuing, (C) unless the Company shall have agreed to pay and shall pay, to such Tax Indemnitee on demand, and on an After-Tax Basis, all reasonable out-of-pocket costs and expenses that such Tax Indemnitee may

incur in connection with contesting the asserted Taxes, including all reasonable legal, accounting and investigatory fees and disbursements, (D) unless the Company shall have provided the Tax Indemnitee with an opinion of counsel selected by the Company and reasonably acceptable to the Tax Indemnitee that a reasonable basis exists for the contest of such Tax Claim; provided, that if the contested issue shall have previously been decided by a court of competent jurisdiction pursuant to the contest provisions of this Section 12.2(g), such opinion shall be that, as a result of a change in law or fact, it is more likely than not that the Tax Indemnitee will prevail, (E) unless, if such contest involves payment of the Tax, the Company either advances to the Tax Indemnitee on an interest-free basis, and with no after-tax cost to such Tax Indemnitee, the amount of such Tax (a “Tax Advance”) or pays such Tax Indemnitee the amount payable by the Company under this Section 12.2 with respect to such Tax, (F) unless 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 in respect of the Facility that could be raised in any other year (including any future year) not barred by the statute of limitations, exceeds $10,000, (G) unless the Company shall acknowledge in writing its liability to indemnify the Tax Indemnitee hereunder in respect of such Tax Claim if the contest is not successful; provided, that such acknowledgment of liability will not be binding if the contest is resolved on a basis from which it can be established that the Company would not be required to indemnify the Tax Indemnitee under this Section 12.2 in the absence of such acknowledgement, or (H) in the case of a judicial appeal, if the appeal is to the U.S. Supreme Court.

(v) Waiver of Indemnification. Notwithstanding anything to the contrary contained in this Section 12.2, a Tax Indemnitee will not be required to contest and may in its sole discretion settle any Tax Claim without the Company’s consent if such Tax Indemnitee shall waive its rights to indemnification pursuant to this Section 12.2 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 as a result of the Tax Indemnitee’s declination to take action with respect to the Tax Claim).

(h) Reports.

(i) If any report, statement or return is required to be filed by a Tax Indemnitee with respect to any Tax that is subject to indemnification under this Section 12.2, the Company shall (A) notify the Tax Indemnitee in writing of such requirement not later than 30 days prior to the date such report, statement or return is required to be filed (determined without regard to extensions) and (B) either (y) if permitted by Applicable Laws and not otherwise directed by the Tax Indemnitee, prepare such report, statement or return for the appropriate Tax Indemnitee in such manner as will show the ownership of the Facility by the Owner Lessor for United States federal, state and local income tax purposes (if applicable), send a copy of such report, statement or return to the Tax Indemnitee, and timely file such report, statement or return with the appropriate taxing authority or (z) if the Company is not permitted by law to file such report, statement or return, or if so directed by the Tax Indemnitee, prepare and furnish to such Tax Indemnitee not later than 30 days prior to the date such report, statement or return is required to be filed (determined without regard to extensions) a proposed form of such

report, statement or return for filing by the Tax Indemnitee; provided, however, that if such report, statement or return requires information within the control of the Tax Indemnitee and its Affiliates, and not available to the Company or its Affiliates, that is not provided to the Company within a reasonable amount of time of the Company’s request, the Company shall instead prepare (and furnish to the Tax Indemnitee within the time frame discussed above) a draft of such report, statement or return by completing those portions of such report, statement or return which can be completed based upon the information then available to the Company (and the Company otherwise agrees to provide the Tax Indemnitee with the information in respect of the transactions contemplated by the Operative Documents that is within its control and is necessary to file such report, statement or return).

(ii) Each Tax Indemnitee and the Company will timely provide the other, at the Company’s expense, with all information in its possession that the other party may reasonably require and request to satisfy its obligations under this Section 12.2(h), but only if and to the extent that such Tax Indemnitee is legally entitled to furnish such information. The Company (A) shall hold each Tax Indemnitee harmless on an After-Tax Basis from and against all liabilities 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 Company pursuant to this Section 12.2(h) in preparing and filing such report, statement or return and (B) shall indemnify each Tax Indemnitee for all liabilities, costs and expenses (including the attorneys’, accountants’ and other professional fees for tax related filings or reviews) of such Tax Indemnitee with respect to all returns, reports or statements to which this Section 12.2(h) applies.

(i) Non-Parties. If a Tax Indemnitee is not a party to this Agreement, the Company may require such Tax Indemnitee to agree in writing, in a form reasonably acceptable to the Company, to the terms of this Section 12.2 prior to making any payment to such Tax Indemnitee under this Section 12.2. Subject to the preceding sentence, the Company’s obligations under this Section 12.2 shall inure to the benefit of each and every Tax Indemnitee without regard to whemer such Tax Indemnitee is a party to this Agreement.

(j) Construction Period. To the extent that any Tax Claim would be indemnifiable by the Company under Section 12.2(a), but constitutes a Tax Claim related to the Facility prior to the Lease Commencement Date for which a Tax Indemnitee seeks indemnification, then with respect to the period from the Construction Closing Date to the Lease Commencement Date, the Company shall not be obligated to indemnify any Tax Indemnitee other than the Owner Lessor pursuant to Section 12.2(a) for such Tax Claim (it being understood and agreed the foregoing shall not limit the Company’s obligation pursuant to Section 12.2(a) to indemnify the Owner Lessor for any Tax Claim resulting from the Owner Lessor’s obligations pursuant to the next sentence, but shall be subject to the recourse limitations set forth in Section 2.18, to the extent applicable). Subject to the provisions of Section 12.3, the Owner Lessor shall indemnify and keep harmless each Tax Indemnitee from any Tax Claim that would be indemnifiable by the Company pursuant to Section 12.2(a) but for the provisions of the preceding sentence.

(k) Withholding Taxes.

(i) The Owner Lessor shall withhold any Taxes required to be withheld on any payment to the Owner Participant or any Noteholder. The amount payable to the Owner Participant or any Noteholder shall be reduced by the amount of any withholding Taxes required to be withheld by the Owner Lessor pursuant to the preceding sentence and the Company and Owner Lessor shall have no liability or obligation to any Person with respect to any withholding Taxes, except to the extent that such withholding Taxes arise as the result of a Change in Law, in which case the Company shall be responsible for, and shall indemnify and hold harmless the Owner Lessor and any Tax Indemnitee (without duplication of any indemnification required in Section 12.2(a)), on an After-Tax Basis against, such withholding Taxes. In the event there is a Change in Law and a withholding Tax is otherwise indemnifiable under this Section 12.2(k), any payments made after the Change in Law under the Operative Documents to the Owner Participant or any Noteholder shall be increased to the amount necessary so that the amount received by the Owner Participant and such Noteholder equals the amount that would have been received if no withholding Tax were payable. If a Tax Indemnitee is permitted under Applicable Laws to file or complete a form, certificate or other document that would entitle such Tax Indemnitee to an exemption from or reduction in a withholding Tax indemnified hereunder, the Company shall provide such form, certificate or other document to such Tax Indemnitee on a timely basis and each such Tax Indemnitee hereby covenants to execute and deliver to the Company any such form, certificate or other document in such manner as shall entitle such Tax Indemnitee to enjoy such exemption or reduction to the fullest extent permitted under Applicable Laws with respect to each payment hereunder unless such Tax Indemnitee reasonably determines in its sole discretion that providing such form, certificate or other document will adversely affect it. In accepting and carrying out its duties with respect to withholding Taxes pursuant to this Section 12.2(k), the Owner Lessor shall act as the duly authorized agent of the Company under the withholding provisions of Chapter 3 of the Code. The Company shall file notice of such appointment with the Office of the Assistant Commissioner (International) in accordance with Treasury Regulation § 1.1441 -7(c). Such agency shall terminate in the event that Changes in Law are amended so as to release the Company of the obligation to withhold Taxes with respect to payments made by the Company under the Facility Lease and in any event upon termination or expiration of the Facility Lease.

(ii) If and to the extent the Owner Lessor has attempted to comply with its obligation to withhold Taxes in accordance with clause (i) and a Tax Claim regarding withholding Taxes is made against the Owner Lessor, as between the Company and the Owner Lessor, the Company shall be responsible for, and the Company shall indemnify and hold harmless the Owner Lessor (without duplication of any indemnification required by Section 12.2(a)) on an After-Tax Basis against, such Tax Claim.

Section 12.3 Limit on the Owner Lessor’s Indemnity Obligations. (a) Each Indemnitee and Tax Indemnitee agrees that the Owner Lessor’s obligations to indemnify and hold harmless any such Indemnitee or Tax Indemnitee, as the case may be, under this Article XII are not individual or personal obligations of the Owner Lessor, but solely in its capacity as

Owner Lessor, and that such obligations of the Owner Lessor shall be limited to net amounts that the Owner Lessor receives under Section 12.1(a) (as specified in the parenthetical set forth in Section 12.1(g)) on account of the Owner Lessor’s obligations under Section 12.1(g) and Section 12.2(a) (as specified in the parenthetical set forth in Section 12.2(j) on account of the Owner Lessor’s obligations under Section 12.2(j), respectively. To the extent that the Owner Lessor receives insufficient funds under such Section 12.1(a) or such Section 12.2(a) to satisfy its indemnity obligations under Section 12.1(g) or Section 12.2(j), respectively, then such amounts received under such Section 12.1(a) or Section 12.2(a) shall be distributed pro rata to the Owner Participant and the Noteholders based on the ratio of the outstanding Construction Balance of each such Participant.

(b) Nothing in this Article XII is intended as or shall be construed as a limitation on the right of any Indemnitee or Tax Indemnitee to make indemnification, contribution or other claims of any kind against the Company to the extent that such claims otherwise may be made, with respect to any matter, including indemnification for Claims or Tax Claims, as the case may be, by the Company under this Article XII.

(c) To the extent that any indemnity payments of the Owner Lessor contemplated by the first paragraph of this Section 12.3 are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid by the Owner Lessor to a trustee, debtor in possession, receiver or other Person under the Bankruptcy Code, common law or equitable cause, then to such extent, the Indemnitee or Tax Indemnitee, as the case may be, who received any such payments from the Owner Lessor (or any portion thereof) shall repay any such amounts to the Owner Lessor, or as may otherwise be directed by a court of competent jurisdiction.

(d) The indemnification obligations of the Owner Lessor under this Article XII shall survive and be reinstated to the same extent, for the same period and in the same manner as the indemnification obligations of the Company.

(e) The right of any Indemnitee or Tax Indemnitee to seek indemnification from the Owner Lessor under this Article XII is subject to and conditioned upon compliance by any such Indemnitee or Tax Indemnitee, as the case may be, with the notice, cooperation, appointment of counsel, contest rights and other provisions in Section 12.1 and Section 12.2, as the case may be, except that any reference in such Sections to the “Company” shall be deemed to be a reference to the “Owner Lessor”.

Section 12.4 Environmental Indemnity. The Company agrees to indemnify, protect, defend and hold harmless, and does hereby indemnify each Indemnitee from and against any and all Environmental Claims imposed or incurred or suffered by or asserted against such Indemnitee in any way relating to or resulting from or arising out of or attributable to, in whole or in part:

(a) the presence in, on, at, under, from or relating to the Facility, the Site, any Component or any portion of any thereof of any Hazardous Substance, or any Releases of any Hazardous Materials in, on, at, under, onto, from or relating to, the Facility, the Site, any Component or any portion of any thereof,

(b) any activity (including construction of the Facility) carried on or undertaken with respect to the Facility, the Site, any Component or any portion of any thereof, and whether by the Company or any of its Affiliates or any predecessor thereof or any employees, agents, sublessees, contractors or subcontractors of the Company, any of its Affiliates or any predecessor in connection with the handling, treatment, removal, storage, decontamination, clean-up, transport or disposal of any Hazardous Materials that at any time are located or present on, under or from, or that at any time migrate, flow, percolate, diffuse or in any way move onto or under the Facility, the Site, any Component or any portion of any thereof,

(c) loss of or damage to any property or the environment arising from, or in any way related to the Facility, the Site, any Component or any portion of any thereof, the Company or any of its Affiliates (including clean-up costs, response costs, remediation and removal costs, cost of corrective action, costs of financial assurance, fines and penalties and natural resource damages), or death or injury to any Person, and all expenses associated with the protection of wildlife, aquatic species, vegetation, flora and fauna, and any mitigative action required by or under Environmental Laws, in each case arising from, or in any way related to the Facility, the Site any Component or any portion of any thereof, the Company or any of its Affiliates,

(d) any actual or alleged claim concerning lack of compliance with Environmental Laws by the Facility or the Owner Lessor, the Company or any of the Company’s Affiliates with respect to the Facility (including any claim arising from the failure or alleged failure to obtain or comply with any Governmental Approval required by any Environmental Law for the construction or operation of the Facility), the Site, any Component or any portion of any thereof, or any act or omission causing an Environmental Condition that requires remediation or would allow any Governmental Authority to record a Lien against the Facility, the Site, any Component or any portion thereof, or

(e) any contamination of any property or natural resources arising in connection with the generation, use, handling, storage, transport or disposal of any such Hazardous Material, in each case arising from, or in any way related to, the Facility, the Site any Component or any portion of any thereof, the Company, any of its Affiliates, and irrespective of whether any of such activities were or will be undertaken in accordance with Applicable Laws.

Notwithstanding the foregoing provisions of this Section 12.4, the Company shall not be obligated to indemnify an Indemnitee under this Section 12.4 for any Claim to the extent that such Claim is attributable to the gross negligence or willful misconduct of such Indemnitee or is subject to the exclusion set forth in Section 12.1(b)(i).

ARTICLE XIII

SUPPLEMENTAL FINANCING OF REQUIRED MODIFICATIONS; OPTIONAL

REFINANCINGS; SUPPLEMENTAL FINANCING OF COST OVERRUNS, ETC.; RIGHT

OF OWNER PARTICIPANT TO ASSUME LESSOR NOTES.

(iii) the Additional Lessor Notes shall have a final maturity date no later than the date that is three (3) years prior to the expiration date of the Basic Lease Term or, if either is then in effect or already elected by the Company, the Renewal Lease Term or the FMV Renewal Lease Term, and will be fully repaid out of additional Basic Lease Rent or Renewal Lease Rent, as adjusted pursuant to the Operative Documents;

(iv) appropriate adjustments to Basic Lease Rent, Renewal Lease Rent, the EBO Amount, the EBO Date, the FPO Amount and Termination Values (determined without regard to any tax benefits associated with such Required Modifications unless the Owner Participant is making an Additional Equity Contribution) shall be made to protect the Owner Participant’s Net Economic Return;

(v) the Company shall have paid (or arranged for payment to be made from the proceeds of the Additional Lessor Notes or the Additional Equity Contribution), on an After-Tax Basis, all reasonable out-of-pocket costs and expenses incurred by the other Funding Parties (including the reasonable fees and expenses of counsel to such Funding Parties), in each case, to the extent incurred in connection with any financing pursuant to this Section 13.1;

(vi) no Company Event of Default or Significant Company Default has occurred and is continuing unless the Modifications to be constructed with the proceeds of the Additional Lessor Notes and/or Additional Equity Contributions shall cure such default;

(ix) the Owner Participant shall have received (A) a favorable legal opinion of tax counsel selected by the Owner Participant to the effect that such Supplemental Modification Financing will not result in any unindemnified incremental tax risk to the Owner Participant or any of its Affiliates, (B) an indemnity from the Company against any such incremental tax risks in form and substance reasonably satisfactory to the Owner Participant or (C) any other indemnity arrangement against such incremental tax risks satisfactory to the Owner Participant;

(x) the Owner Participant shall suffer no adverse accounting effects under GAAP;

(xi) to the extent that, at the time of such Supplemental Modification Financing, a safe harbor exists under Section 467 of the Code, which, if met, would provide that such Supplemental Modification Financing does not cause any adverse impact under Section 467 of the Code to the Owner Participant or Owner Lessor, such safe harbor shall be satisfied; and

(xii) the Company shall have made, or delivered, such representations, warranties, covenants, opinions or certificates as the Owner Participant or the Indenture Trustee may reasonably request.

(c) Notwithstanding the prior provision dealing with the financing of Modifications through the Facility Lease, the Company shall at all times have the right, subject to compliance with Section 7.24 and Section 7.25, to finance Modifications to the Facility other than through the Facility Lease; provided, that no Lien on the Facility or any part thereof or interest therein shall arise as a result thereof.

Section 13.2 Optional Refinancing of the Lessor Notes. (a) On and after the Lease Commencement Date, the Company shall have the right, exercisable on up to six (6) occasions during the Basic Lease Term (but no more than two (2) times in any five (5) year period), to request the Owner Lessor to, and the Owner Lessor in such event shall, refund or refinance any of the Lessor Notes, in whole or in part (and the Owner Participant agrees to instruct the Owner Lessor to take actions to refund or refinance the Lessor Notes as provided herein), in either the public or private market through the borrowing of loans and/or the issuance of New Lessor Notes; provided, that any refinancing under this Section 13.2 shall be subject to the conditions set forth in Section 2.10 and Section 7.2 of the Indenture and satisfaction of the following additional conditions:

Section 13.3 Financing of Cost Overruns. Etc. (a) At any time prior to the Lease Commencement Date, if the Company shall determine that the sum of the Available

101

Owner Participant Commitment and the amounts on deposit in Accounts are insufficient to pay for any Cost Overruns or are insufficient to pay any scheduled principal payments due in respect of the Lessor Notes, then the Company shall be permitted to request, pursuant to a Commitment Increase Request delivered at least ninety (90) days prior to any proposed financing, that the Owner Participant increase its Owner Participant Commitment. The Owner Participant shall have been given the opportunity, but shall have no obligation, to provide all or part of the funds required to finance any such Cost Overruns or such principal payments by increasing its Owner Participant Commitment to make Additional Equity Contributions in such amount, if any, as it may determine in its sole discretion. The Company shall have no obligation to accept and the Owner Participant shall not be obligated to increase its Owner Participant Commitment.

ARTICLE XIV

FORCE MAJEURE, CASUALTY, CONDEMNATION AND EVENT OF LOSS DURING

THE CONSTRUCTION PERIOD

Section 14.1 Force Majeure Event during the Construction Period. (a) If the Company believes that any event of Force Majeure (including an event of Force Majeure resulting from a Casualty or a Condemnation) has occurred during the Construction Period, the Company will provide written notice thereof to the Owner Lessor and the Indenture Trustee within five (5) Business Days of obtaining Actual Knowledge of the underlying event giving rise to such event of Force Majeure. The Company shall also set forth in such notice whether such event of Force Majeure may delay Completion of the Facility, may increase Project Costs or may constitute a Construction Event of Loss. The actual occurrence of an event of Force Majeure shall be subject to the reasonable determination of the Owner Lessor (who shall consult with a nationally recognized engineering firm selected by the Owner Lessor from whom the Owner Lessor and the Company shall receive written confirmation that such determination is reasonable; provided, however that, in the event that such engineering firm is not, or deems itself not, capable of confirming such determination, in whole or in part, such determination may be confirmed by another suitable third-party expert). In connection with any notice given by the Company pursuant to the first sentence of this Section 14.1(a), no payment shall be made under Section 11.4 in connection with such notice until the determination referred to in the preceding sentence is confirmed by such engineering firm or such suitable third-party expert, as the case may be. If the Company fails timely to notify the Owner Lessor of any event of Force Majeure, such event shall not give rise to a Non-Recourse Event, nor shall the Company otherwise be entitled to any limitations on its recourse as a result of such event pursuant to Section 2.18, 11.5, 12.1(g) or 12.2(j). The Company acknowledges and agrees that the failure to obtain any Governmental Approval (or any consequence of such failure) from (i) the Arizona Corporation Commission under Title 40 of the Arizona Revised Statutes (as such statute is in effect on the Construction Closing Date) or (ii) the Arizona Registrar of Contractors under Section 32-1101 of the Arizona Revised Statutes (as such statute is in effect on the Construction Closing Date), in either case, with respect to any of the transactions contemplated by the Transaction Documents

106

shall in no event constitute an event of Force Majeure for purposes of this Section 14.1 or any other provision of the Operative Documents.

(b) In the event the Company believes any such event of Force Majeure not constituting a Construction Event of Loss will cause Completion of the Facility to occur later than the Outside Completion Date, the Company shall request that the Outside Completion Date be extended by the Owner Lessor for the minimum period reasonably necessary to achieve Completion in light of such event of Force Majeure (an “Extension Request”). In the event the Company believes any such event of Force Majeure not constituting a Construction Event of Loss will cause an increase to Project Costs by an amount that would create a shortfall in the Construction Budget, the Company shall make a Commitment Increase Request in an amount equal to such shortfall pursuant to Section 2.7 of the Construction Agency Agreement (or arrange additional funding commitments in an amount equal to such shortfall pursuant to Section 13.3(b)). Any such Extension Request or Commitment Increase Request shall be in writing delivered to the Owner Lessor not later than ten (10) Business Days after obtaining Actual Knowledge of such event of Force Majeure (but in no event later than thirty (30) days after the occurrence of such event of Force Majeure) and shall set forth a revised Construction Budget and shall contain a certification that (i) states the facts and circumstances giving rise to such event of Force Majeure, the expected duration of such event of Force Majeure and the date the Company reasonably believes Completion of the Facility will be achieved and (ii) confirms that the sum of (A) the Available Owner Participant Commitment (including any requested increases thereto pursuant to Section 2.7 of the Construction Agency Agreement), any amounts remaining on deposit in the Accounts and any additional funding commitments arranged pursuant to Section 13.3(b) and (B) any Casualty Insurance Proceeds, Condemnation Proceeds and other proceeds paid or amounts made available with respect to such event of Force Majeure, will be adequate to achieve Completion within such requested extension period; provided, however, that if such information is not reasonably available, the Company shall identify such information not available and indicate when it expects to obtain such information. In the event the Company fails timely to make any such request (or fails to include the required information in such request to the extent such information is reasonably available to the Company), such event shall not give rise to a Non-Recourse Event and the Company shall not otherwise be entitled to any limitations on its recourse as a result of such event pursuant to Section 2.18, 11.5, 12.1(g) or 12.2(j). The Owner Lessor shall consult with the Engineering Consultant and consider any Extension Request in its sole discretion and the Owner Participant shall consider any Commitment Increase Request in its sole discretion and either (i) such parties shall accede to such requests (whereupon the provisions of Section 14.3 shall be applicable, including with respect to the disbursement of any amounts deposited in the segregated account established pursuant to Section 14.2(c)) or (ii) the Owner Lessor shall be entitled to declare a Company Event of Default has occurred (whereupon the provisions of Article XI shall be applicable); provided, however, that the accession of the Owner Participant with respect to any Commitment Increase Request shall not be required to the extent that additional funding commitments in an amount equal to the shortfall shall have been arranged pursuant to Section 13.3(b). The Company shall also supply to the Owner Lessor, the Indenture Trustee and the Engineering Consultant such other information as either of the Owner Lessor or the Indenture Trustee may reasonably request in connection with an event of Force Majeure.

107

Section 14.2 Casualty and Condemnation Occurrences during the Construction Period.

(a) Notice of Casualty and Condemnation. If, during the Construction Period, all or any portion of the Facility suffers a Casualty or the use of, access to, occupancy of or title to the Facility or any part thereof is the subject of a Condemnation, the Company shall give notice thereof to the Owner Lessor and the Indenture Trustee within three (3) Business Days of obtaining Actual Knowledge thereof (or in the case of a Casualty or Condemnation constituting a Construction Event of Loss, within five (5) Business Days of the occurrence thereof). The Company shall also give the Owner Lessor and the Indenture Trustee written notice of any potential Condemnation proceedings with respect to the Facility within five (5) Business Days of obtaining Actual Knowledge thereof.

(b) Casualty and Condemnation Proceedings. Unless the Company shall have delivered a Recourse Notification pursuant to Section 3.1(b) of the Construction Agency Agreement, the Owner Lessor shall have the right to control the negotiations with (i) the insurers in the case of any such Casualty and (ii) the relevant Governmental Authorities in the case of any such Condemnation proceedings; provided, that the Owner Lessor may direct the Company to, and the Company shall if so directed, control such negotiations and choose to participate in such negotiations in any manner as the Owner Lessor may elect.

(c) Casualty Insurance Proceeds and Condemnation Proceeds. All Casualty Insurance Proceeds on account of any damage to or destruction of the Facility or any part thereof during the Construction Period and all Condemnation Proceeds payable with respect to a Condemnation occurring during the Construction Period shall be paid directly to a segregated account controlled by the Indenture Trustee, or if received by the Company, shall be held in trust and immediately paid over to the Indenture Trustee to be deposited into such account. Any portion of Casualty Insurance Proceeds and Condemnation Proceeds to be held in such segregated account by the Indenture Trustee shall be invested in Permitted Investments in accordance with Section 4.2(c) of the Indenture.

(d) Casualty or Condemnation Not Arising from Force Majeure. In the event any Casualty or Condemnation not arising from an event of Force Majeure occurs that does not constitute a Construction Event of Loss, the Company shall certify (which certification shall be subject to confirmation by the Engineering Consultant) not later than thirty (30) days after the occurrence of such Casualty or Condemnation that (A) the Facility will be restored and completed in accordance with the terms this Agreement and the terms of the Construction Agency Agreement and the Facility can reasonably be expected to achieve Completion on or prior to the Outside Completion Date and (B) the estimated costs to complete the construction of the Facility are anticipated to be less than or equal to the sum of (i) the Available Owner Participant Commitment (including any requested increases thereto pursuant to Section 2.7 of the Construction Agency Agreement), the amount of funds remaining on deposit in the Accounts and any additional funding commitments arranged pursuant to Section 13.3(b) and (ii) any Casualty Insurance Proceeds, Condemnation Proceeds and other proceeds or amounts received or

108

reasonably anticipated to be received as a result of a Casualty and Condemnation. In the event the Company fails timely to comply with the provisions of the immediately preceding, sentence, the Owner Lessor may declare that such failure constitutes a Company Event of Default (whereupon, the provisions of Article XI shall apply).

(e) Casualty or Condemnation Arising from Force Majeure. In the event that any Casualty or Condemnation arising from an event of Force Majeure occurs, the provisions of Section 14.1 shall apply to such Casualty or Condemnation.

(f) Construction Event of Loss. Any Construction Event of Loss shall constitute a Company Event of Default (whereupon the provisions of Article XI shall apply).

(g) Construction Period Application. The provisions of this Section 14.2 shall not apply after the Lease Commencement Date.

Section 14.3 Repair. The Company shall be permitted to request disbursements out of Casualty Insurance Proceeds and Condemnation Proceeds held by the Indenture Trustee pursuant to Section 14.2(c) solely for the reconstruction, restoration, repair and completion of construction of the Facility and request Advances therefor, subject to the satisfaction of any applicable conditions in Section 14.2(c) and the following conditions: (i) the Owner Lessor and the Indenture Trustee shall have received a revised Construction Budget, which Construction Budget shall evidence that the sum of (x) the Available Owner Participant Commitment (including any requested increases thereto pursuant to Section 2.7 of the Construction Agency Agreement), the amount of funds remaining on deposit in the Accounts and any additional funding commitments arranged pursuant to Section 13.3(b) and (y) any Casualty Insurance Proceeds, Condemnation Proceeds and other proceeds or amounts received or receivable by the Indenture Trustee as a result of a Casualty and Condemnation shall be sufficient in the reasonable opinion of the Engineering Consultant to complete the Facility on or before the Outside Completion Date (subject to any extension of such date pursuant to Section 14.1(b)), (ii) the Indenture Trustee shall have received a requisition with respect to each requested disbursement in form and substance reasonably satisfactory to the Owner Lessor (A) requesting funds in an amount not exceeding the cost of work completed or incurred since the last disbursement, together with reasonably satisfactory evidence of the stage of completion and of performance of the work in a good and workman-like manner and in accordance with the EPC Contract and the other Construction Documents and (B) confirming that sufficient funds are available to complete the Facility (the reasonableness of such requisition and supporting evidence and confirmations reasonably satisfactory to the Owner Lessor except that no such confirmation shall be required if the aggregate amount to be requested in connection with such Casualty or Condemnation in any one fiscal year is less than $5,000,000), (iii) at the time of any such disbursement, no Company Event of Default shall have occurred and be continuing and (iv) the Company shall take such other actions as Owner Lessor may reasonably request in connection therewith.

(a) So long as no Significant Company Default or Company Event of Default has occurred and is continuing, in the event of a Burdensome Buyout Event or a Deemed Loss, the Company may in each such case, in lieu of purchasing the Facility (and terminating the Facility Lease) in accordance with the terms of the Facility Lease, upon not less than 30 days’ written notice to the Owner Participant and the Indenture Trustee, purchase, subject to the limitations set forth in Section 15.1(b) below, all of the Member Interest (any purchase under this Section 15.1 being referred to as the “Special Company Transfer”) on the applicable Termination Date at a price equal to the Special Company Transfer Amount determined as of the date of such transfer and keep the Facility Lease (and the Lessor Notes and the Certificates) in effect; provided, that such purchase either (i) is approved by the Required Noteholders or (ii) would not, in the reasonable opinion of the Indenture Trustee (acting pursuant to an opinion of counsel), result in more than an immaterial risk of the merger of the interests of the Owner Lessor and the Company in the Facility Lease or the Site Sublease (which opinion, if to the effect that such a purchase would result in more than an immaterial risk of such a merger of interests, must be evidenced by an opinion of counsel selected by the Indenture Trustee and reasonably satisfactory to the Company). On the applicable Termination Date, the Company (or its designee) shall pay to the Owner Participant the Special Company Transfer Amount determined as of such date, plus all amounts due and payable to the Owner Participant on such date under the Operative Documents (including all costs and expenses of the Owner Participant and all sales, stamp, ad valorem, rental, license, property use, value added and other Taxes covered by Section 12.2 associated with the Special Company Transfer pursuant to this Section 15.1, to the extent such amounts have not otherwise been reimbursed by the Company pursuant to this Section 15.1, it being understood that any transfer pursuant to this Section 15.1 shall not be considered a voluntary or involuntary transfer, assignment, sale or other disposition for purposes of Section 12.2). Subsequent to such transfer, the Company and the Owner Lessor may, without the consent of any other Funding Party, waive the Deemed Loss or the Burdensome Buyout Event that gave rise to the Special Company Transfer event and the Facility Lease shall continue in full force and effect in accordance with its terms.

(b) The Company’s ability to elect a Special Company Transfer pursuant to Section 15.1(a) shall be subject to the limitations in Sections 9.1 (a)(i), (ii), (iii), (iv), (v), (vi) and 9.1(d) and to the following additional condition that the Owner Participant shall have suffered no detriment from such Special Company Transfer (as compared to those that would have resulted had the Company terminated the Facility Lease and purchased the Facility) or (y) the Owner Participant shall be indemnified by the Company from any such reasonably anticipated detriment in a matter reasonably satisfactory to the Owner Participant.

(c) Concurrently with the payment of all sums required to be paid pursuant to Section 15.1(a) (or on such later date of transfer of the Member Interest in accordance with clause (ii) below) (i) the Company shall cease to have any liability to the Owner Participant with respect to the Operative Documents, except for obligations (including those contained in Section 12.1 and Section 12.2 hereof and the Tax Indemnity Agreement) surviving pursuant to the express terms of any Operative Document or that have otherwise accrued but have not been paid

110

as of such date, (ii) the Owner Participant will transfer (by an appropriate instrument of transfer) the Member Interest to the Company (or its designee) and (iii) the Owner Participant shall cease to have any liability or obligations under the Operative Documents or otherwise in respect of the Facility, except for liabilities and obligations surviving pursuant to the express terms of any Operative Document or that have otherwise accrued, but not been paid as of such date; provided, however, that if the Lien of the Security Documents has not been terminated or discharged, such transfer shall not be made to the Company, but shall be made to the Company’s designee promptly upon the Company’s designation of such designee and such designee will agree not to transfer the Member Interest to the Company until such Lien is terminated or discharged. At the time of any transfer under this Section 15.1, the Owner Participant shall represent and warrant as to the absence of Owner Participant’s Liens and Liens attributable to the OP Guarantor, the Equity Investor or the Owner Participant on the Member Interest. It is understood and agreed among the parties hereto that the transaction contemplated by this Section 15.1 shall not effect a merger of the Company’s interest in the Facility, the Facility Lease and Ground Interest with the Owner Lessor’s interest in the Facility and the Ground Interest.

(d) The Company will pay, on an After-Tax Basis, all reasonable out-of-pocket costs and expenses incurred by the other Funding Parties (including the reasonable fees and expenses of counsel to such Funding Parties) in each case to the extent incurred in connection with any transfer pursuant to this Section 15.1.

Section 15.2 Assignment of Facility Lease. The Company covenants and agrees that, except as otherwise provided in Section 7.22 hereof or Section 21.4 of the Facility Lease, it shall not assign the Facility Leasehold Interest (or any part thereof) without the prior written consent of the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee (acting on the instruction of the Required Noteholders); provided, however, that the Company may assign the Facility Leasehold Interest, in whole but not in part, without such consent as collateral for its Master Indenture Secured Obligations; provided, further, that, neither the trustee nor the holders of the Master Indenture Secured Obligations may take assignment of the Facility Leasehold Interest (or any part thereof) by foreclosure or otherwise under the Master Indenture, nor shall the trustee or the holders of the Master Indenture Secured Obligations cause the Facility Leasehold Interest (or any part thereof) to be assigned to any other Person in connection with a foreclosure or otherwise under the Master Indenture, without the prior written consent of the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee (acting on the instruction of the Required Noteholders). Except as otherwise provided in the Transaction Documents, the Company shall not assign the Facility Leasehold Interest if such assignment could result in the Facility being considered tax exempt use property.

ARTICLE XVI

MISCELLANEOUS

Section 16.1 Bankruptcy of Lessor Estate. (a) If (i) all or any part of the Lessor Estate becomes the property of a debtor subject to the reorganization provisions of the Bankruptcy Code, (ii) pursuant to such reorganization provisions, the Owner Participant is

111

required, by reason of the Owner Participant being held to have recourse liability to the debtor or the trustee of the debtor directly or indirectly, to make payment on account of any amount payable as principal or interest on the Lessor Notes and (iii) the Indenture Trustee actually receives any Excess Amount (as defined below) which reflects any payment by the Owner Participant on account of clause (ii) above, the Indenture Trustee shall promptly refund to the Owner Participant such Excess Amount. For purposes of this Section 16.1, “Excess Amount” means the amount by which such payment exceeds the amount that would have been received by the Indenture Trustee if the Owner Participant had not become subject to the recourse liability referred to in clause (ii) above. Nothing contained in this Section 16.1 shall prevent the Indenture Trustee from enforcing any personal recourse obligations (and retaining the proceeds thereof) of the Owner Participant as contemplated by this Agreement (other than referred to in clause (ii)).

(b) The Indenture Trustee agrees that should the Lessor Estate become a debtor subject to the provisions of the Bankruptcy Code, it shall upon the written request of the Owner Participant, and provided that the making of the election hereinafter referred to is permitted to be made by it under Applicable Law and will not have any adverse impact on any Noteholder, the Indenture Trustee or the Collateral other than as contemplated by the preceding paragraph, make the election referred to in Section 1111 (b)(1)(A)(i) of the Bankruptcy Code or any successor provision if, in the absence of such election, the Indenture Trustee would have recourse against the Owner Participant for the payment of the Indebtedness represented by the Lessor Notes in circumstances in which such Noteholders or the Indenture Trustee, as the case may be, would not have recourse under the Indenture if the Lessor Estate had not become a debtor under the Bankruptcy Code.

Section 16.2 Transfer of Title; Assumption of Lessor Notes by the Company. Each of the parties hereto (other man the Company) covenants and agrees that if the Company elects to terminate the Facility Lease and purchase the Facility, the Ground Interest and the Project Document Interest pursuant to the terms of the Facility Lease and the other Operative Documents, each such Person will execute and deliver appropriate documentation transferring all right, title and interest in the Facility, the Ground Interest and the Project Document Interest to the Company (including such bills of sale and other instruments and documents as the Company shall reasonably request to evidence (on the public record or otherwise) such transfer and the vesting of all right, title and interest in and to the Facility, the Ground Interest and the Project Document Interest in the Company). If the Company, in connection with such purchase, elects to assume the obligations of the Owner Lessor pursuant to the Indenture, each of the other parties hereto will execute and deliver appropriate documentation permitting the Company to assume such obligations on the basis of full recourse to the Company, maintaining the Lien of the Security Documents on the Facility, the Ground Interest, the Project Document Interest and the other Collateral, releasing the Owner Participant and the Owner Lessor from all future obligations in respect of the Lessor Notes and all of the Operative Documents and all such other actions as are reasonably necessary to permit such assumption by the Company.

Section 16.3 Amendments and Waivers. No term, covenant, agreement or condition of this Agreement may be terminated, amended or compliance therewith waived (either generally or in a particular instance, retroactively or prospectively) except by an instrument or instruments in writing, executed by each of the Company, the Owner Lessor, the

112

Independent Manager, the Trust Company, the Indenture Trustee, the Owner Participant and, subject to the provisions of Section 7.2 of the Indenture, the Required Noteholders (provided, that, in the case of Section 7.24, Section 7.25 or Section 11(q), such instrument or instruments shall only be required to be executed by the Company, the Owner Lessor and the Owner Participant); provided, however, that Sections 2.3 (as such section relates to Noteholders), Article V, Article X, Article XII (as it relates to any Noteholder), this Section 16.3 and the definition of “Required Noteholders” may not be terminated, amended or compliance therewith waived without an instrument or instruments in writing executed by all of the Noteholders; and provided, further, that Article X and Article XII (as it relates to the Indenture Trustee) may not be terminated, amended or compliance therewith waived without an instrument or instruments in writing executed by the Indenture Trustee.

In addition, the indemnifications by the Company under Section 12.1, Section 12.2 and Section 12.4 shall, subject to Section 12.1(b) and Section 12.2(b), respectively, expressly survive the expiration or early termination (in either case, for whatever reason) of the Construction Agency Agreement or the Facility Lease or the transfer or other disposition of the respective interests of the other Funding Parties in, to and under this Agreement and the other Operative Documents.

Section 16.6 Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of, and shall be enforceable by, the parties hereto and their respective successors and assigns as permitted by and in accordance with the terms hereof, including each successive holder of the Member Interest pursuant to a transfer permitted under Section 9.1 and each successive holder of the Lessor Notes pursuant to a transfer permitted by the Indenture.

The Owner Lessor shall notify the Company of its intent to exercise any such rights to purchase any such interests at least sixty (60) days prior to the date set forth in clause (i) above and within sixty (60) days of the occurrence of the date set forth in clause (ii) above.

Each of the Company and the Owner Lessor further agrees that it shall pay for its own costs related to such sale.

(c) Unless the Owner Lessor shall have previously notified the Company that it intends to exercise the purchase rights set forth in Section 16.20(b), upon notice to the Company not later than thirty (30) days prior to the date the last payment of Basic Lease Rent is due at the end of the Basic Lease Term, the Owner Lessor shall have the right to lease all, but not less than all, of the interests then owned by the Company in the Fuel Handling Facilities or the Common Facilities for a period of years specified in such notice, which period shall be one year up to that number of years remaining until the end of the useful life of the Facility as determined by an independent appraiser selected (and paid for) by the Owner Lessor at the time of such election.

Within thirty (30) days of the expiration of any such lease period, upon notice, the Owner Lessor shall have the right to (i) lease any such Fuel Handling Facilities and/or Common Facilities for a subsequent period pursuant to similar terms and conditions, including an ongoing right to extend, or (ii) purchase such Fuel Handling Facilities and/or Common Facilities in exchange for the fair

118

market value of such interests, as determined by an independent appraiser selected (and paid for) by the Owner Lessor. At the end of any subsequent lease term elected pursuant to clause (i) of the previous sentence, the lessee shall be entitled to make the same elections to continue to lease or to purchase or to do neither, as is set forth in the prior sentence. Each of the Owner Lessor and the Company agrees to enter into all appropriate documentation to effect such sale as soon as is commercially feasible. Each of the Company and the Owner Lessor further agrees that it shall pay for its own costs related to such sale.

(d) To the extent the Owner Lessor does not elect to exercise any lease or purchase right set forth in Section 16.20(c), the Owner Lessor shall have no further obligation to the Company relating to the Fuel Handling Facilities or the Common Facilities, other than the payment of any accrued but unpaid rent relating to such facilities.

(i) Committed Take Out of Long-Term Debt — If the Company or a Restricted Subsidiary has received a binding commitment from any bank, investment banking firm, savings and loan association, insurance company, or similar institution to refund or purchase any of its Long-Term Debt (as defined in accordance with Accounting Requirements) at its Stated Maturity or any earlier date (or, if due on demand, or payable in respect of any required purchase of such Debt by the Company or such Restricted Subsidiary, at any date on which demand may be made), then for the period beginning on the refinancing date set forth in such commitment and thereafter to Stated Maturity, the principal and interest which will be coming due on the new Long-Term Debt after it is refinanced or purchased shall be used in making pro forma calculations required by the Master Indenture instead of the existing principal and interest on the Long-Term Debt being purchased or refinanced.

(ii) Amortization of Principal of Balloon Debt — The amount of principal of Balloon Debt for any preceding or succeeding fiscal year or 12-month period ending on the last day of the most recent fiscal quarter immediately prior to the making of such calculation may be calculated using the original principal amount of such Balloon Debt amortized over the full term (from date of issuance to Stated Maturity) of such Debt with level annual principal payments and at an assumed interest rate equal to the rate borne by such Balloon Debt on the date of calculation.

(iii) Consensual Sinking Fund for Principal of Balloon Debt — If the Company or any Restricted Subsidiary obligated thereon shall deliver to the trustee under the Master Indenture a resolution of the Governing Body of the Company or such Restricted Subsidiary providing for the retirement of (and the instrument creating such Balloon Debt shall permit the retirement of), or for the establishment of a sinking fund for, such Balloon Debt according to a fixed schedule stated in such resolution, then for so long as all installments previously scheduled have been paid or deposited to the sinking fund established with respect to such Debt on or before the times required by such schedule,

(v) Interest Rate of Variable Rate Debt — In making prospective calculations of interest on Variable Rate Debt, a rate equal to the average rate borne by such Debt during the 24-month period immediately prior to such calculation shall be used; provided that if such Debt has not been outstanding during all or any of the prior 24 months, then the interest rate on comparable debt shall be used; provided further, however, that if there is no comparable debt which was outstanding during such 24-month period, an interest rate equal to 110% of the current yield for U.S. Department of Treasury obligations of a comparable maturity to the longest interest rate mode of such Variable Rate Debt (other than the long or fixed rate mode) shall be used to calculate the interest rate on such Variable Rate Debt.

(vi) Guarantees — Actual amounts paid or required to have been paid by the Company or any Restricted Subsidiary on account of Guarantees shall be included in historical calculations of Annual Debt Service Requirements of the Restricted Group. If the Company or a Restricted Subsidiary guaranteeing such Debt is required by an Accountant which is Independent to show the probability of such payments and the estimated amount of such payments payable in the Company’s financial reports, then the estimated probable amount of principal, premium, if any, and interest coming due on such Debt shall be included in any computation of the prospective Annual Debt Service Requirements of the Company or such Restricted Subsidiary for such period or fiscal year, until such time as the entity whose obligation is guaranteed or obligated on such Debt cures all defaults related thereto.

(vii) Commercial Paper — With respect to any Debt issued in the form of commercial paper with maturities not exceeding 270 days, the interest rate on such Debt shall be calculated in the manner provided in clause (v) of this definition. If such commercial paper is not backed by a Credit Support Agreement, the principal of such Debt shall be calculated in the manner provided in clauses (ii) or (iii) of this definition.

(viii) Payments made by a Credit Provider — If the Company or any Restricted Subsidiary has entered into a Credit Support Agreement in connection with an issue of Debt, payments due under the Credit Support Agreement, from either the Company or such Restricted Subsidiary, shall be included in such calculation except to the extent that the payments are already taken into account under clauses (i) through (vii) above. With

respect to any calculation of historic data, only those payments actually made in the subject period shall be taken into account in making such calculation and, with respect to prospective calculations, only those payments reasonably expected to be paid by the Company or such Restricted Subsidiary to the Credit Provider in reimbursement of amounts actually paid plus applicable interest in the subject period shall be taken into account in making the calculation.

(ix) Hedge Agreements — In the event there shall have been issued or entered into in respect of all or a portion of any Debt a Hedge Agreement and (A) interest on such Debt or portion of such Debt is payable at a variable rate of interest for any future period of time or is calculated at a varying rate per annum, (B) a fixed rate is specified as payable by the Company or any Restricted Subsidiary issuing such Debt in such Hedge Agreement or such Debt taken together with the Hedge Agreement results in a net fixed rate payable by the Company or such Restricted Subsidiary for such period of time (the “Hedge Fixed Rate”), (C) the counterparty to such Hedge Agreement is rated in the two highest generic rating categories by any Rating Agency and (D) an event of default has not occurred and is continuing under such Hedge Agreement, then such Debt shall be deemed for all purposes hereunder to bear interest for such period of time at the Hedge Fixed Rate and all provisions hereof applicable for fixed rate debt shall apply with respect thereto.

(x) Calculation of Principal of Periodic Funding Obligations and Discount Obligations — In the case of Periodic Funding Obligations and Discount Obligations on any date, the principal amount thereof payable upon the Maturity shall be the lesser of the amount payable upon the Stated Maturity thereof or the amount that would be payable if the Maturity of such Debt were such date. Except for the purpose of making pro forma calculations under Article IV of the Master Indenture, the principal amount of a Periodic Funding Obligation shall not include any amount not then advanced and outstanding thereunder. The principal amount of a Periodic Funding Obligation shall be reduced as the principal amount of such Periodic Funding Obligation is paid or otherwise reduced. Such payment or reduction shall be treated as a payment unless the Company retains the right to have such amount readvanced. If any such payment or reduction shall not be treated as a payment because the Company retains the right to readvance such amount, once that right to readvance expires or is terminated, such payment or reduction may

thereupon be treated as a payment under such Sections. The principal amount of such a Periodic Funding Obligation may be evidenced from time to time by an Officers’ Certificate delivered to the Owner Participant and the Indenture Trustee and the holder of such Periodic Funding Obligation. Following any timely objection by the holder, the Owner Participant and the Indenture Trustee may require such other evidence of the principal amount of such Periodic Funding Obligation as shall be satisfactory to the Indenture Trustee and the Owner Participant.

(xi) Calculation of Principal and Interest on Certain Notes With Periodic Rollovers of Principal — For purposes of calculating the principal payable on any portion or advance of Debt as to which the principal matures periodically and is subject to rollovers at the election of the obligor, the Company may elect to use either the most immediate Stated Maturity of such portion of the loan or advance if it intends to pay such Debt at such Stated Maturity (including any premium) or the last Stated Maturity of such portion of the principal or advance on such Debt. The applicable prior provisions shall apply for purposes of calculating the interest rate on such Debt.

In such case, the average of the determinations of the three appraisers shall be conclusive and binding on the Owner Participant and the Company, unless the determination of one appraiser is disparate from the middle determination by more than twice the amount by which the third determination is disparate from the middle determination, in which case the determination of the most disparate appraiser shall be excluded and the average of the remaining two determinations shall be conclusive and binding on the Owner Participant and the Company.

4. General Conditions applying to all Insurance required under this Schedule 7.29

(a) Amendment by the Owner Lessor and Owner Participant. The Owner Lessor and the Owner Participant may at any time amend the requirements and approved insurance companies (i.e., insurance companies which did not meet the ratings requirements of this Schedule but were acceptable to the Owner Lessor) of this Schedule due to (i) new information not known by the Company, the Owner Lessor, the Owner Participant or the Secured Parties on the Construction Closing Date or (ii) changed circumstances after the Construction Closing Date which in the reasonable judgment of the Owner Lessor and the Owner Participant (which opinion shall be confirmed by the Insurance Consultant) either renders such coverage materially inadequate or materially reduces the financial ability of the approved insurance companies to pay claims.

(b) Amendment Due to Commercial Unfeasibility.

(i) If any insurance required to be maintained by Company pursuant to this Schedule (including the limits or deductibles or any other terms under policies for such insurance) ceases to be available on a commercially reasonable basis at the time of renewal, the Company shall provide written notice to the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee, accompanied by a letter from the Company’s insurance broker stating that such insurance is unavailable on a commercially reasonable basis. Such notice shall be given not less than thirty (30) days prior to the scheduled date for renewal of any such

policy. Upon receipt of such notice by the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee, the Owner Lessor, the Owner Participant and the Company shall immediately enter into in good faith negotiations in order to obtain an alternative to such insurance.

(ii) In the event that the Owner Lessor, the Owner Participant and the Company cannot reach a resolution acceptable to such parties within five (5) days, the Owner Lessor shall make arrangements for the formation of an insurance panel consisting of the Company’s insurance advisor (or broker), the Owner Lessor’s insurance advisor (or broker) and an independent insurance expert from an internationally recognized insurance brokerage firm, chosen by the Owner Lessor and reasonably acceptable to the Company. Such independent expert shall conduct a separate review of the relevant insurance requirements of this Schedule, and the market for such insurance at the time, giving due consideration to the representations of both insurance advisors, and upon conclusion of such review shall issue a written report stating whether such insurance is available or unavailable on a commercially reasonable basis.

(iii) If the insurance expert concludes that such insurance is not available on a commercially reasonable basis, the insurance expert shall provide a written recommendation not less than fifteen (15) days before the date for renewal of such insurance which shall be conclusive and binding on each of the Company, the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee. The Owner Lessor and the Owner Participant shall issue a waiver to the Company for a period of one (1) year upon the insurance expert certifying that the relevant insurance is not available on a commercially reasonable basis and the Company having implemented the recommendation of the insurance expert.

(iv) All fees, costs and expenses associated with the insurance panel (including the review by the insurance expert) shall be for the sole account of the Company.

(c) Application of Proceeds. All payments received by any Participant or the Company under any insurance policies obtained by the Company pursuant to Section 7.29 of the Participation Agreement and Sections 2(g), (h), (i) and (j) of this Schedule shall promptly be paid to the Indenture Trustee and deposited in a segregated account established by the Indenture Trustee pursuant to Section 4.2(c) of the Indenture for application in accordance with the provisions thereof and the other Operative Documents.

(d) Conditions.

(i) The Company shall promptly notify the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee of any loss in excess of $5,000,000 covered by any insurance maintained pursuant to Sections 2(g), (h), (i) and (j).

(ii) All policies of insurance required to be maintained pursuant to Sections 2(g), (h), (i) and (j), shall provide that the proceeds of such policies shall be payable solely to the Indenture Trustee, so long as the Lien of the Security Documents shall not have been terminated or discharged, and thereafter, to the Owner Lessor pursuant to a standard first mortgage endorsement substantially equivalent to the Lenders Loss Payable Endorsement 438BFU or New York Standard Mortgage Endorsement without contribution. All policies (other than in respect to liability or workers compensation insurance) shall insure the interests of the Owner Lessor, the Owner Participant and the Secured Parties (and such other Persons as may be required by the Operative Documents) regardless of any breach or violation by the Company of warranties, declarations or conditions contained in such policies, any action or inaction of the Company or others, or any foreclosure relating to the Facility or any change in ownership of all or any portion of the Facility (the foregoing may be accomplished by the use of the Lender Loss Payable Endorsement required above).

(iii) Subject to Section 14.2(b) of the Participation Agreement (in the case of insurance carried under Sections 2(g) and (h)), a loss under any insurance required to be carried under Sections 2(g), (h), (i) and (j), shall be adjusted with the insurance companies, including the filing in a timely manner of appropriate proceedings, by the Company, subject to the approval of the Owner Lessor, if such loss is in excess of $5,000,000. In addition the Company may in its reasonable judgment consent to the settlement of any loss, provided that in the event that the amount of the loss exceeds $10,000,000 the terms of such settlement is concurred with by the Owner Lessor.

(iv) All policies of insurance required to be maintained pursuant to this Schedule shall be endorsed so that if at any time should they be canceled, or coverage be reduced which affects the interests of the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Secured Parties, such cancellation or reduction shall not be effective as to the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the

Secured Parties for 30 days (except for non-payment of premium which shall be for 10 days) after receipt by the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Secured Parties of written notice of such insurer of such cancellation or reduction.

(v) All policies of insurance required to be maintained pursuant to Sections 2(g), (h), (i) and (j) shall not include any annual or term aggregate limits of liability or clause requiring the payment of additional premium to reinstate the limits after loss except as regards the insurance applicable to the perils of flood and earth movement.

(e) Evidence of Insurance. On the Construction Closing Date and on an annual basis at each policy anniversary, the Company shall furnish, or cause to be furnished, to the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee and the Pass Through Trustees, approved certification of all required insurance. Such certification shall be executed by each insurer or by an authorized representative of each insurer where it is not practical for such insurer to execute the certificate itself. Such certification shall identify underwriters, the type of insurance, the insurance limits and the policy term and shall specifically list the special provisions enumerated for such insurance required by this Schedule. Upon request, the Company will promptly furnish the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee and the Pass Through Trustees with copies of all insurance policies, binders and cover notes or other evidence of such insurance relating to the insurance required to be maintained or caused to be maintained by the Company.

(f) Report. On the Construction Closing Date and annually thereafter, the Company shall furnish, or cause to be furnished, to the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee and the Pass Through Trustees, a report of an independent insurance broker, signed by an officer of the broker, stating that all premiums then due have been paid and that, in the opinion of such broker, the insurance then carried or to be renewed is in accordance with the terms of this Schedule. In addition the broker will advise the Owner Lessor, the Owner Participant and, so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee and the Pass Through Trustees in writing promptly of any default in the payment of any premium and of any other act or omission on the part of the Company which may invalidate or render unenforceable, in whole or in part, any insurance being maintained by the Company pursuant to this Schedule.

(g) Failure to Maintain Insurance. In the event the Company fails, or fails to cause the EPC Contractor or the Operator, to take out or maintain the full insurance coverage required by this Schedule, the Owner Lessor, the Owner Participant or,

so long as the Lien of the Security Documents has not been terminated or discharged, the Indenture Trustee, upon 30 days’ prior notice (unless the aforementioned insurance would lapse within such period, in which event notice should be given as soon as reasonably possible) to the Company of any such failure, may (but shall not be obligated to) take out the required policies of insurance and pay the premiums on the same. All amounts so advanced thereof by the Owner Lessor, the Owner Participant or the Indenture Trustee shall become an additional obligation of the Company to the Owner Lessor, the Owner Participant or the Indenture Trustee, as the case may be, and the Company shall forthwith pay such amounts to the Indenture Trustee together with interest thereon at the Overdue Rate from the date so advanced.

(h) No Duty of Owner Lessor, Owner Participant or Indenture Trustee. No provision of this Schedule or any provision of the Participation Agreement or any other Transaction Document shall impose on the Owner Lessor, the Owner Participant or the Secured Parties any duty or obligation to verify the existence or adequacy of the insurance coverage maintained by the Company, nor shall the Owner Lessor, the Owner Participant or the Secured Parties be responsible for any representations or warranties made by or on behalf of the Company to any insurance company or underwriter. Any failure on the part of any of the foregoing to pursue or obtain the evidence of insurance required by this Schedule from the Company and/or failure by any of the foregoing to point out any noncompliance of such evidence of insurance shall not constitute a waiver of any of the requirements of this Schedule.

(i) Maintenance of Insurance. The Company shall at all times maintain or cause to be maintained the insurance coverage required under the terms of the Transaction Documents.
