Owner Lessor agrees, and each of the Owner Participant and the Owner Trustee agree to cause the Owner Lessor to, at the request of Midwest and at the sole cost and expense of NRG on an After-Tax Basis, take such actions as may be necessary for the Owner Lessor to take as the owner of the Facility for purposes of obtaining the valid and effective issue, transfer or amendment, as the case may be, of all Governmental Approvals to the extent the same are required for the use, ownership, operation or maintenance of the Facility, the Facility Site, the Undivided Interest, the Ground Interest or any Component by Midwest or any permitted assignee of Midwest in the manner contemplated by the Operative Documents. Midwest shall pay on an After-Tax Basis all reasonable costs and expenses (including, without limitation, the reasonable fees and expenses of counsel) of Owner Lessor and each other Person party to an Operative Document incurred in connection with any such action. It is understood and agreed that, with respect to any action requested of it, and taken by it, under

this Section 10.8, the Owner Lessor, the Owner Participant and the Owner Trustee shall make no representation or warranty as to, and shall have no responsibility for the effectiveness of such action to accomplish or promote the objective intended by the Person making such request.

SECTION XI COVENANTS OF THE LEASE INDENTURE TRUSTEE

Section 11.1. The Indenture Trustee’s Liens. Neither the Lease Indenture Company nor the Lease Indenture Trustee will directly or indirectly create, incur, assume or suffer to exist any Indenture Trustee’s Lien attributable to it and arising out of events or conditions not related to its rights in the Indenture Estate or the administration thereof, and will promptly notify the Owner Participant, the Equity Investor, the Owner Trustee, Midwest and NRG in writing of the imposition of any such Lien of which it has actual knowledge and shall promptly, at its own expense, take such action as may be necessary to duly discharge such Indenture Trustee’s Lien.

provided that the terms “omission,” “gross negligence” and “willful misconduct,” when applied with respect to the Owner Trustee, the Owner Participant, the OP Guarantor, the Equity Investor, the Owner Lessor, the Lease Indenture Trustee, the Pass Through Trustee or any Certificateholder or any Affiliate of any thereof, shall not include any liability imputed as a matter of law to such Indemnitee solely by reason of such entity’s interest in the Facility or the

Facility Site or such Indemnitee’s failure to act in respect of matters which are or were the obligation of Midwest under this Agreement or any other Operative Document.

(c) Insured Claims. Subject to the provisions of paragraph (e) of this Section 12.1, in the case of any Claim indemnified by NRG hereunder which is covered by a policy of insurance maintained by NRG, 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 NRG, to cooperate, at the sole cost and expense of NRG, with insurers in exercise of their rights to investigate, defend or compromise such Claim.

(d) After-Tax Basis. NRG 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 NRG in writing of any Claim as to which indemnification is sought; provided that the failure so to notify NRG shall not reduce or affect NRG’s liability which it may have to such Indemnitee under this Section 12.1. Any amount payable to any Indemnitee pursuant to this Section 12.1 shall be paid within fifteen (15) days after receipt of such written demand therefor from such Indemnitee, accompanied by a 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 hereof 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 NRG receives notification of such Claim accompanied by a written statement describing in reasonable detail the Claims which are the subject of and basis for such indemnity and the computation of the amount so payable, NRG 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. NRG shall have the right to investigate and so long as no Material Lease Default or Lease Event of Default shall have occurred and be continuing, NRG shall have the right in its sole discretion, to defend or compromise any Claim for which indemnification is sought under this Section 12.1 which NRG acknowledges in writing to the applicable Indemnitee is subject to indemnification hereunder; provided that no such defense or compromise shall involve any danger of (i) foreclosure, sale, forfeiture or loss of, or imposition of a Lien on any part of the Undivided Interest, the Ground Interest, the Trust Estate or the Indenture Estate or the impairment of the Facility in any material respect or (ii) any criminal liability being incurred or any material adverse effect on such Indemnitee, provided, further, that no Claim shall be compromised by NRG 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, NRG 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 NRG 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 NRG’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 NRG’s expense with all reasonable requests of NRG in connection therewith and will provide NRG with all information not within the control of NRG as is reasonably available to such Indemnitee which NRG may reasonably request; provided, however, that such Indemnitee shall not, unless otherwise required by Requirement of Law, be obligated to disclose to NRG or any other Person, or permit NRG or any other Person to examine (i) any income tax returns of the Owner Participant or (ii) any confidential information or pricing information not generally accessible by the public possessed by the Owner Participant (and, in the event that any such information is made available, NRG 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 NRG, or the insurers under a policy of insurance maintained by NRG, undertake the defense of such Indemnitee with respect to a Claim (with counsel reasonably satisfactory to each such Person such Indemnitee and without reservation of rights against 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 NRG or such insurers. Notwithstanding the foregoing, an Indemnitee may participate at its own expense in any judicial proceeding controlled by NRG pursuant to the preceding provisions, but only to the extent that such party’s participation does not in the reasonable opinion of counsel to NRG 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 NRG 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, without limitation, the reasonable fees and expenses of such separate counsel) shall be borne by NRG. So long as no Lease 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 NRG unless (i) the Indemnitee waives its rights to indemnification hereunder or (ii) NRG 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 NRG under this Section 12.1 is in fact paid in full by NRG or an insurer under an insurance policy maintained by NRG, NRG (so long as no Lease 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) 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 NRG hereunder, it shall promptly pay over to NRG 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

NRG or any of its insurers has paid in respect of such Claim; provided that so long as a Material Lease Default or Lease Event of Default shall have occurred and is continuing such amount may be held by the Owner Lessor as security for Midwest’s and NRG’s respective obligations under the Operative Documents.

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 as a condition to making any such claim for indemnity under this Section 12.1.

Section 12.2. General Tax Indemnity.

(a) Indemnity. Except as provided in paragraph (b), NRG agrees to indemnify on an After-Tax Basis each of the Owner Participant, the OP Guarantor, the Equity Investor, the Owner Lessor, the Trust Company in its individual capacity, the Owner Trustee, the OP Member, the Noteholders, the Lease Indenture Trustee, the Lease Indenture Company in its individual capacity, the Pass Through Trustee and the Pass Through Company in its individual capacity, their respective successors and assigns, the past and present partners or members of or holders of the ownership interests in, as the case may be, the Owner Participant and the Affiliates of each of the foregoing (each a “Tax Indemnitee”) and to hold each Tax Indemnitee harmless from and to defend each Tax Indemnitee against all Taxes that are imposed upon any Tax Indemnitee, the Facility, the Facility Site, the Undivided Interest, the Ground Interest, or any portion or Component thereof or any interest therein, or upon any Operative Document or interest therein, arising out of, in connection with or relating to, any of the following:

(i) the construction, financing, refinancing, acquisition, operation, warranty, ownership, use, possession, maintenance, repair, lease, condition, alteration, modification, restoration, refurbishing, return, purchase, sale or other disposition, insuring, sublease, or other use or non-use of the Facility, Undivided Interest, Ground Interest or the Facility Site, or any portion or Component thereof or any interest therein;

(ii) the conduct of the business or affairs of Midwest at the Facility and the Facility Site;

(v) Taxes imposed on a Tax Indemnitee that arise out of, or are caused by, any act or omission of such Tax Indemnitee (or any Related Party thereof) that is expressly prohibited by any Operative Document or by a breach by such Tax Indemnitee (or any Related Party thereof) of any of its representations, warranties or covenants under any Operative Document;

(vi) Taxes arising out of, or caused by, any voluntary assignment, sale, transfer or other voluntary disposition, or any involuntary transfer or disposition resulting from a bankruptcy or similar proceeding for relief of debtors in which such Tax Indemnitee is a debtor, by (or a foreclosure by a creditor of) (A) the Owner Participant of any of its Beneficial Interest, (B) the Owner Lessor of all or any of its interest in the Facility or the Facility Site, or (C) the Lease Indenture Trustee of any interest in the Lessor Notes or the Indenture Estate unless (i) such transfer or disposition occurs during the continuance of a Lease Event of Default, or (ii) such transfer or disposition is required under, or occurs pursuant to, the Operative Documents and the price paid is other than Fair Market Sales Value;

(vii) Taxes arising in connection with Owner Participant’s Liens or Owner Lessor’s Liens;

(viii) Taxes imposed on any assignee or successor-in-interest to a Tax Indemnitee to the extent any such Taxes exceed the Taxes that would have been imposed had no assignment or transfer taken place determined under the law as in effect on the date of transfer; provided that this exclusion shall not apply to the computation of the gross-up amounts necessary to make a payment on an After-Tax Basis, nor to a transferee, assignee or successor in interest that acquires the interest of a Tax Indemnitee pursuant to a transfer or disposition in connection with the exercise of remedies during the continuance of a Lease Event of Default;

(ix) Taxes that are included as a part of Transaction Costs;

(x) Taxes imposed on, based on, or measured by any compensation that any Owner Trustee or the Lease Indenture Trustee receives for its services;

(xii) other than with respect to the Certificateholders, the Lease Indenture Trustee and the Pass Through Trustee or any Related Party in respect of any thereof (a “Lender Indemnitee”), Taxes resulting from the Owner Lessor not being treated as a grantor trust or a nonentity for federal, state or local income tax purposes;

(xiii) Taxes attributable to the failure of any Tax Indemnitee to comply with certification, information, documentation, reporting or other similar requirements concerning the 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 and obligated to comply with such requirement and shall have been given timely written notice of such requirement by NRG;

(xiv) Taxes imposed on a Tax Indemnitee where the Tax Indemnitee’s breach of its contest obligations under Section 12.2(g) effectively precludes NRG’s ability to contest the Taxes;

(xv) Taxes imposed on any Tax Indemnitee resulting from an amendment, modification, supplement or waiver to any Operative Document which was not requested by Midwest or NRG and as to which Midwest or NRG is not a party and the Tax Indemnitee (or, in the case of the Owner Participant, the Facility Lessor if acting at the express direction of the Owner Participant) is a party unless such amendment, modification, supplement or waiver (A) was required by applicable law or the Operative Documents, (B) may be necessary or

appropriate to, and is in conformity with, any amendment, modification, supplement or waiver to any Operative Document agreed to by Midwest or NRG in writing, or (C) is made while a Lease Event of Default shall have occurred and be continuing;

(xvi) Taxes imposed under Section 4975 of the Code, Section 406 of ERISA or any comparable laws of any governmental authority to the extent resulting from action by such Tax Indemnitee other than, in the case of the Owner Participant, the taking of any action at the request or direction of NRG;

(xvii) Taxes imposed to the extent such Taxes result from the Tax Indemnitee (and in the case of the Owner Lessor, only if acting at the written direction of the Owner Participant) being organized under the laws of a jurisdiction other than the United States or any State thereof (other than, in the case of a Lender Indemnitee, such Taxes which did not exist under law in effect on the date such Lender Indemnitee became a party to this transaction);

(xviii) Any Taxes imposed on a Tax Indemnitee to the extent that such taxes would not have been imposed but for the activities of such Tax Indemnitee unrelated to the transactions contemplated hereby;

(xix) Taxes imposed on a Tax Indemnitee in the nature of interest, penalties, fines and additions to tax (i) payable as a result of such Tax Indemnitee’s failure to file, in a procedurally proper manner and on a timely basis, any tax reports, returns or statements as to which NRG has timely notified such Tax Indemnitee in writing of the requirement to file, unless such failure is otherwise caused by the failure of NRG to fulfill its obligations, if any, with respect to such return (including provision of information sufficient to enable such Tax Indemnitee to file such report, return or statement), or (ii) to the extent not attributable to or resulting from Taxes for which an indemnity is provided hereunder; and

(xx) Taxes for as long as such Taxes are being contested pursuant to the contest provisions contained in Section 12.2(g).

(c) Payment. Each payment required to be made by NRG to a Tax Indemnitee pursuant to this Section 12.2 shall be paid either (i) when due directly to the applicable taxing authority by NRG 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 latest of (A) fifteen (15) days following NRG’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) in the case of amounts which are being contested pursuant to such paragraph (g), fifteen (15) days following the time and in accordance with a final determination of such contest or (C) in the case of any indemnity demand for which NRG has requested review and determination pursuant to paragraph (d) below, the completion of such review and determination, but in no event later than

the date which is three (3) Business Days prior to the date payment of such Taxes is due. Any amount payable to NRG pursuant to paragraph (e) or (f) below shall be paid within fifteen (15) days after the Tax Indemnitee realizes a Tax Benefit giving rise to a payment under paragraph (e) or receives a refund or credit giving rise to a payment under paragraph (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. Upon the final determination of any contest pursuant to paragraph (g) below in respect of any Taxes for which NRG has made a Tax Advance, the amount of NRG’s obligation under paragraph (a) above shall be determined as if such Tax Advance had not been made. Any obligation of NRG 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 ten (10) days of such final determination.

(d) Independent Examination. Within fifteen (15) days after NRG receives any computation from the Tax Indemnitee, NRG may request in writing that an independent public accounting firm selected by the Tax Indemnitee and reasonably acceptable to NRG review and determine on a confidential basis the amount of any indemnity payment by NRG to the Tax Indemnitee pursuant to this Section 12.2 or any payment by a Tax Indemnitee to NRG pursuant to paragraph (e) or (f) below. The Tax Indemnitee and NRG 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 such accounting firm shall agree in writing in a manner satisfactory to the Tax Indemnitee, or NRG, as the case may be, to maintain the confidentiality of such information, and provided further that neither any Tax Indemnitee nor NRG shall be required to disclose any of its tax returns or books that such Tax Indemnitee or NRG, as the case may be, reasonably deems to be confidential in connection with such verification, and the parties hereto agree that such Tax Indemnitee, or NRG, as the case may be, shall have sole control over the positions taken with respect to such party’s tax returns and filings. The fees and disbursements of such accounting firm will be paid by NRG; provided that such fees and disbursements will be paid by the Tax Indemnitee if the accountants determine that the present value of the total payments as calculated by the Tax Indemnitee is more than 105 percent of the present value of the correct payments (such present values in each case to be determined by the Discount Rate). In the event such accounting firm determines that such 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 NRG and the Tax Indemnitee. The parties hereto 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 Participation Agreement or any other Operative Document are not within the scope of the independent accountant’s responsibility. Such accounting firm shall be requested to make its determination within thirty (30) days.

(e) Tax Benefit. If, as the result of any Taxes paid or indemnified against by NRG under this Section 12.2, the aggregate Taxes actually paid by the Tax Indemnitee in connection with such payment for any taxable year and not subject to indemnification pursuant to this Section 12.2 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 by NRG under paragraph (a) above and provided no Lease 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 Lease Event of Default has been cured), such Tax Indemnitee shall pay to NRG 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 resulting to the Tax Indemnitee from 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 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 NRG 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 NRG must indemnify the Tax Indemnitee pursuant to this Section 12.2 without regard to paragraph (b) hereof.

(f) Refund. If a Tax Indemnitee obtains a refund or credit or would have received such refund or credit but for a counterclaim or other claim not indemnified by NRG hereunder against which such refund or credit has not been applied (an “offset refund or credit”) of all or part of any Taxes paid, reimbursed or advanced by NRG pursuant to this Section 12.2, the Tax Indemnitee shall pay to NRG within fifteen (15) days of such receipt, or in the case of an offset refund or credit, within fifteen (15) days of the resolution of such contest (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) plus (y) an amount equal to any Tax Benefit realized by such Tax Indemnitee by reason of such payment to NRG (determined using the same assumptions as set forth in the second sentence under the definition of After-Tax Basis), provided that (A) if at the time such payment is due to NRG a Lease Event of Default shall have occurred and be continuing, such amount shall not be payable until such Lease Event of Default has been cured, and (B) the amount payable to NRG pursuant to this sentence shall not exceed the amount of the indemnity payment in respect of such refunded or credited Taxes that was made by NRG (and such excess shall be carried forward and applied to reduce pro tanto any subsequent obligations of NRG to make payments to such Tax Indemnitee pursuant to this Section 12.2). 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 NRG must indemnify the Tax Indemnitee pursuant to this Section 12.2 without regard to paragraph (b) hereof. If, in connection with a refund or credit of all or part of any Taxes paid, reimbursed or advanced by NRG pursuant to this Section 12.2, a Tax Indemnitee receives an amount representing interest on such refund or credit, the Tax Indemnitee shall pay to NRG within fifteen (15) days (1) the amount of such interest that shall be fairly attributable to such Taxes paid, reimbursed or advanced by NRG prior to the receipt of such refund or credit (net of Taxes payable in respect of the receipt or accrual of such interest) and (2) any Tax savings resulting from payments made by the Tax Indemnitee under this Section 12.2.

(g) Contest.

(i) Notice of Contest. If a written claim is made by any taxing authority against a Tax Indemnitee for any Taxes with respect to which NRG may

be required to indemnify against hereunder (a “Tax Claim”), such Tax Indemnitee shall give NRG written notice of such Tax Claim promptly after its receipt, and shall furnish NRG with copies of such Tax Claim and all other writings received from the taxing authority to the extent relating to such claim, provided that failure so to notify NRG shall not relieve NRG of any obligation to indemnify the Tax Indemnitee hereunder except to the extent such failure effectively precludes NRG from contesting such Tax. The Tax Indemnitee shall not pay such Tax Claim until at least thirty (30) days after providing NRG with such written notice, unless (a) the Tax Indemnitee is required to do so by law or regulation and (b) in the written notice described above, the Tax Indemnitee has notified NRG of such requirement.

(ii) Control of Contest. Subject to subsection (g)(iii) below, NRG will be entitled to contest (acting through counsel selected by NRG and reasonably satisfactory to the Tax Indemnitee), and control the contest of, any Tax Claim if (i) such Tax Claim may be segregated procedurally and contested independently from tax claims for which NRG is not obligated to indemnify the Tax Indemnitee, provided that if the Tax Indemnitee reasonably determines at any time that permitting NRG to conduct or continue to conduct such contest could have material adverse business or other consequences to such Tax Indemnitee, such Tax Indemnitee shall have the right to control or reassert control over such contest, or (ii) the Tax Indemnitee requests that NRG control such contest; provided that in the case of any such contest pursuant to (i) or (ii) NRG shall use all reasonable efforts to contest such Tax Claim in its own name, and provided further that such contest shall be at NRG’s sole cost and expense. NRG shall consult in good faith with the Tax Indemnitee and its counsel and shall provide the Tax Indemnitee with copies of any reports or claims issued by the relevant auditing agent or taxing authority, but the decisions regarding what actions to be taken shall be made by NRG in its sole judgment.

(iii) In the case of all other Tax Claims, the Tax Indemnitee will contest the Tax Claim at NRG’s expense if NRG shall request that the Tax be contested (in accordance with subsection (g)(iii) below), and the following rules shall apply with respect to such contest:

(A) the Tax Indemnitee will control the contest of such Tax Claim in good faith (acting through counsel selected by the Tax Indemnitee and reasonably satisfactory to NRG),

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

(C) the Tax Indemnitee conducting such contest shall consult with and keep reasonably informed NRG and its designated counsel with respect to such Tax Claim and shall

consider and consult in good faith with NRG regarding any request (a) to resist payment of Taxes if practical and (b) not to pay such Taxes except under protest if protest is necessary and proper, but the decision regarding what actions to be taken shall be made by the Tax Indemnitee in its sole judgment.

(D) Notwithstanding paragraph (3), above, the Tax Indemnitee shall not otherwise settle, compromise or abandon such contest without NRG’s prior written consent except as provided in paragraph (g)(iv) below.

(iv) Conditions of Contest. Notwithstanding the foregoing, no contest with respect to a Tax Claim will be required or permitted pursuant to this Section 12.2, and NRG shall be required to pay the applicable Taxes without contest, unless:

(A) within thirty (30) days after notice by the Tax Indemnitee to NRG of such Tax Claim, NRG shall request in writing to the Tax Indemnitee that such Tax Claim be contested, provided that if a shorter period is required for taking action with respect to such Tax Claim and the Tax Indemnitee notifies NRG of such requirement, NRG shall use reasonable best efforts to request such contest within such shorter period, and such Tax Indemnitee shall take no action for as long as it is legally able to do so,

(B) no Lease Event of Default has occurred and is continuing,

(C) there is no risk of sale, forfeiture or loss of, or the creation of a Lien (other than a Lease Permitted Lien) on the Facility, Owner Lessor’s or Owner Participant’s interest in the Facility, the Facility Site, the Undivided Interest, the Ground Interest or any portion or Component thereof or any interest therein as a result of such Tax Claim; provided that this clause (C) shall not apply if NRG shall have posted and maintained a bond or otherwise provided security for NRG’s obligations under Section 12.2 satisfactory to the Tax Indemnitee in its reasonable discretion, or the Tax is fully paid in either manner specified in clause (E) below,

(D) there is no risk of imposition of any criminal penalties,

(E) if such contest involves payment of such Tax, NRG will either advance to the Tax Indemnitee on an interest-free basis and with no after-tax cost to such Tax Indemnitee (a “Tax Advance”) or pay such Tax Indemnitee the amount payable by

NRG pursuant to Section 12.2(a) above with respect to such Tax, and such Tax Indemnitee shall promptly pay to NRG any net Tax Benefit recognized which results from any imputed interest deduction arising from such interest free Tax Advance plus any net Tax Benefit recognized which result from making any such payment.

(F) NRG agrees to pay (and pays on demand) and with no after-tax cost to such Tax Indemnitee all reasonable costs, losses and expenses incurred by the Tax Indemnitee in connection with the contest of such claim (including, without limitation, all reasonable legal, accounting and investigatory fees and disbursements),

(G) the Tax Indemnitee has been provided at NRG’s sole expense with an opinion, reasonably acceptable to such Tax Indemnitee, of independent tax counsel of recognized standing selected by NRG and reasonably acceptable to the Tax Indemnitee to the effect that there is a Reasonable Basis for contesting such Tax Claim,

(H) in the case of a judicial appeal, no appeal to the U.S. Supreme Court shall be required of the Tax Indemnitee or shall be permitted by NRG.

(I) In the case of a judicial contest, NRG shall have delivered to the Tax Indemnitee a written acknowledgment of its liability under this Section 12.2 for such Taxes, provided, however, that NRG shall not be bound by its acknowledgment of liability if the contest is resolved on the basis of a written decision of the adjudicator that clearly indicates the basis for the conclusion that NRG has no liability under this Section 12.2 with respect to such Tax, unless NRG’s conduct of the contest has materially prejudiced the Tax Indemnitee.

(v) Waiver of Indemnification. Notwithstanding anything to the contrary contained in this Section 12.2, the Tax Indemnitee at any time may elect to decline to take any action or any further action with respect to a Tax Claim and may in its sole discretion settle or compromise any contest with respect to such Tax Claim without NRG’s consent if the Tax Indemnitee:

(A) waives its right to any indemnity payment by NRG 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 by the Tax Indemnitee’s declination to take action with respect to the Tax Claim), and

(B) promptly repays to NRG any Tax Advance and any amount paid to such Tax Indemnitee under Section 12.2(a) above in respect of such Taxes.

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

(h) Reports.

(i) If any report, statement or return is required to be filed by a Tax Indemnitee with respect to any Tax that is subject to indemnification under this Section 12.2, NRG will (1) notify the Tax Indemnitee in writing of such requirement not later than thirty (30) days prior to the date such report, statement or return is required to be filed (determined without regard to extensions) and (2) either (y) if permitted by applicable law, prepare such report, statement or return for filing by NRG 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 so directed by the Tax Indemnitee or in any event if practicable and if the return to be filed reflects only information in respect of the transactions contemplated by the Operative Documents, prepare and furnish to such Tax Indemnitee not later than thirty (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.

(ii) Each of the Tax Indemnitee or NRG, as the case may be, will timely provide the other, at NRG’s expense, with all information in its possession that the other party may reasonably require and request to satisfy its obligations under this paragraph (h), but only if and to the extent that such Tax Indemnitee is legally entitled to furnish such information.

(i) Non-Parties. If a Tax Indemnitee is not a party to this Agreement, NRG may require such Tax Indemnitee to agree in writing, in a form reasonably acceptable to Midwest, to the terms of this Section 12 (to the extent applicable to such Tax Indemnitee) prior to making any payment to such Tax Indemnitee under this Section.

SECTION XIII MIDWEST’S RIGHT OF QUIET ENJOYMENT

Each party to this Agreement acknowledges notice of, and consents in all respects to, the terms of the Facility Lease, and the Facility Site Sublease and expressly, severally and as to its own actions only, agrees that, so long as no Lease Event of Default has occurred and is continuing, neither it nor any party acting by, through or under such party shall take or cause to be taken any action contrary to Midwest’s rights under the Facility Lease and the Facility Site Sublease, including the right to possession, use and quiet enjoyment of the Undivided Interest and the Ground Interest.

SECTION XIV SUPPLEMENTAL FINANCING OF IMPROVEMENTS; OPTIONAL REFINANCINGS

Section 14.1. Financing Improvements.

Upon the written request of Midwest delivered at least ninety (90) days prior to any proposed financing of the cost of any Required or Non-Severable Improvement, the Owner Lessor, the Lease Indenture Trustee and the Pass Through Trustee agree to cooperate with Midwest to (a) issue Additional Lessor Notes under the Lease Indenture to finance such Improvement which will rank pari passu with the Lessor Notes then outstanding; and (b) execute and deliver an amendment to the Facility Lease to reflect the adjustments required by clause (v) below; provided, however, that 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 the Owner Lessor’s Percentage of any such Improvement by making an Additional Equity Investment in such amount, if any, as it may determine in its sole discretion. Midwest shall have no obligation to accept and the Owner Participant shall not be obligated to provide such Additional Equity Investment. The obligation to finance such Improvement through the issuance of Additional Lessor Notes (any financing of Improvements through the issuance of such Additional Lessor Notes being called a “Supplemental Financing”) is subject to the limitations on incurrence of additional Indebtedness set forth in the Operative Documents and the following additional conditions:

(i) there shall be no more than one such financing in any calendar year;

(ii) Improvements shall be made in compliance with the Operative Documents;

(iii) such Improvement is a Required Improvement;

(iv) the Additional Lessor Notes shall have a final maturity date no later than the expiration date of the Basic Lease Term or any Renewal Term then in effect or already elected by Midwest and will be fully repaid out of additional Basic Lease Rent or Renewal Rent and Termination Value as adjusted pursuant to the Operative Documents;

(v) appropriate adjustments to Basic Lease Rent and Termination Value (determined without regard to any tax benefits associated with such Improvements, unless the Owner Participant is making an Additional Equity Investment) shall also be made to protect the Owner Participant’s Expected Return;

(vi) NRG shall have paid, on an After-Tax Basis, all reasonable out-of-pocket costs and expenses of the Lease Financing Parties, including the reasonable fees and expenses of counsel to the Owner Participant, the Owner Lessor, the Owner Trustee, the Lease Indenture Trustee, the Lease Indenture Company in its individual capacity, the Pass Through Trustee and the Pass

Through Company in its individual capacity, in each case to the extent incurred in connection with any financing or refinancing pursuant to this Section 14;

(vii) no Lease Event of Default shall have occurred and be continuing unless the Improvements to be constructed with the proceeds of the Additional Lessor Notes shall cure such Lease Event of Default, and any such Improvements shall be made in compliance with the Operative Documents;

(viii) the sum of (y) the principal amount of such Additional Lessor Notes and (z) the principal amount of all comparable additional lessor notes used to finance such Improvements pursuant to the Other Facility Lease, is not less than $20 million and not greater than 100% of the cost of the Improvements being financed; provided that the sum of (I) the outstanding balance of the Lessor Notes and (II) all comparable lessor notes issued and outstanding of the Other Owner Lessor under the lease indenture to which such Other Owner Lessor are party never exceeds (x) 90% of the lesser of (1) the fair market value of the Facility taking into account such Improvements, as determined pursuant to the Appraisal Procedure, and (2) the sum of (t) the Purchase Price, (u) the comparable purchase price for the Other Undivided Interest and (v) the cost of the Improvement being financed;

(ix) the Owner Participant shall have received a favorable opinion reasonably satisfactory to it from nationally recognized tax counsel selected by the Owner Participant and reasonably acceptable to NRG, to the effect that such financing would not result in any material indemnified, or any unindemnified, incremental tax risk to the Owner Participant;

(x) the Owner Participant shall not suffer any material adverse accounting effects under GAAP as a result of providing such additional financing;

(xi) the cost of the Improvement, together with the cost of all previous Improvements financed with Additional Lessor Notes is not greater than 25% of the sum of (x) the Purchase Price and (y) the comparable purchase price for the Other Undivided Interest; unless the Facility Lessee shall have received confirmation that after giving effect to the financing in connection with such Improvement, the Lease Debt rating will not fall below BBB- or Baa3 from S&P and Xxxxx’x, respectively;

(xii) Midwest and NRG shall have made or delivered such representations, warranties, covenants, opinions or certificates as the Owner Participant may reasonably request; and

(xiii) such Additional Lessor Notes are issued pursuant to and in accordance with Section 2.13 of the Lease Indenture and Midwest and NRG shall have delivered such certificates, reports and other documents and shall have taken all other actions which are required to be delivered or taken by them pursuant to Section 2.13 of the Lease Indenture.

Notwithstanding the prior provision dealing with the financing of Improvements through the Facility Lease, Midwest shall at all times have the right to finance Improvements to the Facility other than through the Facility Lease; provided that Improvements may only be financed other than through the Facility Lease if such financing would not result in any Lien on the Facility or the Facility Land and shall be subject to the limitations on incurrence of additional Indebtedness contained in the other Operative Documents; provided further, that Required Improvements and Non-Severable Improvements shall automatically, upon being affixed to the Facility, become the property of the Owner Lessor and subject to the Facility Lease.

Section 14.2. Optional Refinancing of Lessor Notes. Midwest will have the right, exercisable on no more than three occasions, for as long as no Material Lease Default or Lease Event of Default shall have occurred and be continuing, to request the Owner Lessor, and the Owner Lessor shall reasonably consider and shall not unreasonably refuse, to refund or refinance the Lessor Notes, in the public or private market, in whole but not in part, through the issuance of new notes to the public (notes issued in such refinancing, the “New Lessor Notes”), to a pass through trust or to such other funding vehicles as may be used at that time or to any other party that is not the Facility Lessee or any Affiliate thereof; provided that any refinancing under this Section 14.2 shall also be subject to satisfaction of the following conditions:

(i) the Owner Lessor shall be able to issue and sell the New Lessor Notes in an amount adequate to accomplish such refunding or refinancing;

(ii) the Owner Participant shall receive an opinion reasonably satisfactory to it from nationally recognized tax counsel selected by the Owner Participant and reasonably acceptable to the Facility Lessee and NRG, to the effect that such refinancing (as opposed to the right to request such refinancing) would not result in any material indemnified or any unindemnified incremental tax risk to the Owner Participant (including tax risks relating to the classification of the Lessor Notes as qualified nonrecourse indebtedness; provided, however, that absent a change in law or judicial, administrative or legislative interpretation thereof after the Plan Effective Date, there would not be incremental tax risk with respect to the allocation of interest expense for foreign tax credit purposes from a refinancing consummated in accordance with the provisions set forth below);

(iii) all documentation in connection with such refinancing shall be reasonably satisfactory to the Owner Lessor, the Owner Trustee, and the Owner Participant and conditions set forth therein shall be met;

(iv) the Owner Participant shall be entitled to a consent fee of $25,000 in connection therewith;

(v) the refinancing shall not result in any other material adverse effect on the rights or interests of the Owner Lessor or the Owner Participant;

(vi) New Lessor Notes shall be issued in compliance with Section 467 of the Code and any proposed, temporary, or final regulation thereunder, in each case as modified and in effect on the date of such issuance.

(vii) all necessary authorizations, approvals and consents in connection with such refinancing shall have been obtained from each Person whose authorization, approval or consent is necessary to consummate such refinancing with respect to the Facility Lessee, the Owner Lessor, the Lease Indenture Trustee and the Pass Through Trustee, and such authorizations, approvals and consents shall be in full force and effect on the closing date of such refinancing;

(viii) the consummation of the transactions contemplated by the refinancing shall not cause the Owner Participant to account for the transactions contemplated by the Operative Documents as other than a “leveraged lease” under FAS 13;

(ix) all payment dates for principal and interest payments on the New Lessor Notes shall become Rent Payment Dates;

(x) on the closing date of such refinancing, each of the Facility Lessee, the Owner Lessor and the Lease Indenture Trustee shall have executed and delivered all appropriate supplements to the Operative Documents that are necessary to consummate such refinancing, in form and substance reasonably satisfactory to the Owner Lessor and the Lease Indenture Trustee;

(xi) each of the Owner Lessor, the Owner Participant, the Lease Indenture Trustee and the Pass Through Trustee shall have received an opinion of counsel for the Facility Lessee on such matters as they may reasonably request and in form and substance reasonably satisfactory to the Owner Participant and the Lease Indenture Trustee;

(xii) Midwest and NRG shall have delivered such certificates, reports and other documents and shall have taken all other actions which are required to be delivered or taken by them pursuant to Section 2.13 of the Lease Indenture;

(xiii) each of the Owner Lessor, the Owner Participant and the Lease Indenture Trustee shall have received from the Facility Lessee a certificate dated the date of the issuance of the New Lessor Notes executed on behalf of the Facility Lessee by an Authorized Officer thereof stating that all conditions precedent to the issuance of such New Lessor Notes have been satisfied or waived;

(xiv) the consummation of any transaction contemplated by such refinancing shall not violate any Requirements of Law except to the extent that such non-compliance with the Requirements of Law would not have a material adverse effect on the Owner Lessor.

(xv) the New Lessor Notes shall have a final maturity date no later than six months after the stated maturity date of the Initial Lessor Notes as set forth in Section 2.4 of the Lease Indenture and the weighted average life to maturity of the New Lessor Notes shall not vary from the remaining weighted average life-to-maturity of the Lessor Notes (immediately prior to such refinancing) by more than six months;

(xvi) the principal amount of the New Lessor Notes shall not exceed by more than 5 percent the remaining principal amount of the Lessor Notes (immediately prior to such refinancing); and

(xvii) the New Lessor Notes shall satisfy the requirements of Temp. Treas. Reg. § 1.861 - 10T(b)(2)(iii), (iv) and (v) and not be excluded by reason of Temp. Treas. Reg. § 1.861 - 10T(b)(4).

Section 14.3. Cooperation. The Owner Participant will cooperate with and reasonably assist Midwest in connection with any refinancing and/or assumption of the Lessor Notes, so long as such refinancing is in accordance with the terms of the Operative Documents. The Owner Participant will execute such agreements and documents as may be necessary with respect to any such refinancing and will instruct the Owner Lessor to act accordingly. Nothing contained in this Section 14 shall limit Midwest’s right to request a refinancing in accordance with Section 14.2, above, refinance the Lessor Notes and to make corresponding changes to Basic Lease Rent and the Termination Value in accordance with the rent adjustment provisions set forth in Section 3 of the Facility Lease.

SECTION XV [RESERVED]

SECTION XVI RIGHT OF FIRST REFUSAL; RIGHT OF FIRST OFFER

Section 16.1. Right of First Offer. In the event the Owner Participant desires to sell, lease, convey or otherwise transfer some or all of its Beneficial Interest other than to an Affiliate of the Owner Participant (other than in connection with the exercise of remedies following a Lease Event of Default) prior to the expiration of the Facility Lease Term, the Owner Participant must first offer to sell such Beneficial Interest to the Facility Lessee on the terms and conditions set forth in this Section 16.1. Such offer shall be made to the Facility Lessee in the form of a proposed term sheet, which proposed term sheet shall include an outline of the price and of the terms, conditions and provisions upon which the Owner Participant would be willing to transfer such Beneficial Interest or any part thereof. The Facility Lessee will thereafter have the right within a period of forty-five (45) days from and after the receipt by the Facility Lessee of such proposed term sheet to notify the Owner Participant of its intent to exercise its right to purchase hereunder. If the Facility Lessee elects to exercise the right provided in the preceding sentence, it shall within sixty (60) days of such notice purchase, and the Owner Participant shall sell, the Beneficial Interest on the same terms and conditions as the offer giving rise to such right. If the Facility Lessee does not give such notice to the Owner Participant within the forty-five (45) day period or does not purchase the Beneficial Interest within sixty (60) days of such notice, the Owner Participant will be free to so sell, lease, convey or otherwise transfer such Beneficial Interest, or a portion thereof, at a price no less than the price set forth in the proposed

term sheet and on terms and conditions, taken as a whole, that, other than in an immaterial respect, are no less favorable to the Owner Participant than the terms and conditions set forth in the proposed term sheet, unless the failure to purchase the Beneficial Interest within sixty (60) days is attributable to the Owner Participant. In the event that the terms or conditions are revised in any way that the price is reduced or any of the other terms and conditions thereof, taken as a whole change the agreement for sale, lease, conveyance or transfer such that the terms and conditions of any such subsequent transaction are less favorable, other than in an immaterial respect, to the Owner Participant, the Owner Participant must again comply with the notice and acceptance provisions of this Section 16.1. It is understood and agreed among the parties hereto that the transaction contemplated by this Section 16.1 shall not effect a merger of the Facility Lessee’s ownership interest in the Facility and the Facility Site with the Owner Lessor’s Interest.

Section 16.2. Right of First Refusal. In the event the Owner Participant desires to sell, lease, convey or otherwise transfer some or all of its Beneficial Interest or cause the Owner Lessor to sell, lease, convey or otherwise transfer its Owner Lessor’s Interest at any time within three years after expiration or termination of the Facility Lease (other than pursuant to Sections 13 and 14 of the Facility Lease) to any Person other than an Affiliate of the Owner Participant, the Facility Lessee or an Affiliate thereof, the Facility Lessee shall have the right, unless such sale, lease, conveyance or transfer is in connection with the exercise of remedies upon a Lease Event of Default, to purchase, lease or otherwise acquire such interest on the terms and conditions set forth in the bid that the Owner Participant intends to accept. The Owner Participant shall give the Facility Lessee prompt written notice of all bona fide offers that have been received from any other Person to purchase or acquire the Owner Lessor’s Interest or Owner Participant’s Beneficial Interest or any part of either during such three-year period following the expiration or termination of the Facility Lease, and which offers it wishes to accept, together with a full and complete statement of the price and all of the material terms, conditions and provisions contained in such offers. The Facility Lessee shall thereafter have the right within a period of forty-five (45) days from and after the receipt by the Facility Lessee of such notice to notify the Owner Participant of its intent to exercise its rights of first refusal. If the Facility Lessee elects to exercise the right provided in the preceding sentence, it shall within sixty (60) days of such notice purchase, and the Owner Participant shall sell, the Beneficial Interest on the same terms and conditions as the offer giving rise to such right. If the Facility Lessee does not give such notice to the Owner Participant within the forty-five (45) day period or does not purchase the Beneficial Interest within sixty (60) days of such notice, the Owner Participant shall be free to proceed under the terms and conditions as set forth in its irrevocable notice to the Facility Lessee, unless the failure to purchase the Beneficial Interest within sixty (60) days is attributable to the Owner Participant. In the event that the terms or conditions are revised in any way that changes the agreement for sale, lease, conveyance or transfer such that the terms and conditions thereof, other than in immaterial respects, are less favorable to the Owner Participant (including any reduction in price or a change in the terms of payment thereof in a manner that is beneficial to the potential purchaser), the Owner Participant must again comply with the notice and acceptance provisions of this Section 16.2. In connection with the Facility Lessee’s exercise of the right of first refusal pursuant to this Section 16.2 with respect to the Owner Lessor’s Interest, the Ground Interest shall be conveyed to the Facility Lessee.

SECTION XVII SPECIAL LESSEE TRANSFER

In the case of a Regulatory Event of Loss or Burdensome Buyout Event under the Facility Lease, the Facility Lessee (or its designee), so long as the Facility Lessee shall remain liable under the Facility Lease to pay Basic Lease Rent and all other payments under the Facility Lease, upon not less than thirty (30) days’ written notice to the Owner Participant and the Lease Indenture Trustee, on the applicable Termination Date, may purchase the Owner Participant’s Beneficial Interest, or, in the case of a Burdensome Buyout Event, the membership interest in the Owner Participant, and keep the Facility Lease in place; provided that (i) the Owner Participant shall not suffer any detriment (including tax or book consequences) from such purchase (as compared to that which would have resulted had the Facility Lessee terminated the Facility Lease and purchased the Owner Lessor’s Interest), (ii) the Facility Lessee satisfies the transferee requirements contained in Section 12.1 hereof applicable to transfers by the Owner Participant, if applicable and (iii) NRG pays all expenses incurred by the other Lease Financing Parties in connection therewith. If the Facility Lessee chooses to purchase the Owner Participant’s Beneficial Interest or the membership interest in the Owner Participant, as the case may be, pursuant to the preceding sentence, on the applicable Termination Date, NRG (or its designee) shall pay to the Owner Participant or to the Equity Investor, as the case may be, the Special Lessee Transfer Amount determined as of such date, plus all amounts due and payable to the Owner Participant or Equity Investor, as the case may be, on such date under the Operative Documents.

Concurrently with the payment of all sums required to be paid pursuant to this Section 17 (or on such later date of transfer of the Owner Participant’s Beneficial Interest or membership interest in the Owner Participant, as the case may be, in accordance with clause (ii) below) (i) the Facility Lessee shall cease to have any liability to the Owner Participant with respect to the Operative Documents, except for obligations surviving pursuant to the express terms of any Operative Document or which have otherwise accrued but not been paid as of such date and (ii) the Owner Participant or the Equity Investor, as the case may be, will transfer (by an appropriate instrument of transfer in form and substance reasonably satisfactory to the Owner Lessor and prepared and recorded at NRG’s expense) the Owner Participant’s Beneficial Interest or membership interest in the Owner Participant, as the case may be, to the Facility Lessee (or its designee); provided, however, that if the Lien of the Lease Indenture has not been terminated or discharged, such transfer shall not be made to the Facility Lessee, but shall be made to the Facility Lessee’s designee promptly upon the Facility Lessee’s designation of such designee and such designee will agree not to transfer the Owner Participant’s Beneficial Interest or the membership interest in the Owner Participant, as the case may be, to the Facility Lessee until such Lien is discharged. The Owner Participant or Equity Investor, as the case may be, shall make any transfer under this Section 17 on an “as is,” “where is” basis, without warranty other than as to the absence of Owner Lessor’s Liens and Owner Participant’s Liens on the Owner Participant’s Beneficial Interest or the membership interest in the Owner Participant, as the case may be. It is understood and agreed among the parties hereto that the transaction contemplated by this Section 17 shall not effect a merger of the Facility Lessee’s leasehold interest in the Facility and subleasehold interest in the Facility Site with the Owner Lessor’s Interest. NRG will pay all reasonable costs and expenses of the Lease Financing Parties in connection with any transfer pursuant to this Section 17. Subsequent to such transfer, the Facility Lessee and the Owner Lessor may, without the consent of the Lease Indenture Trustee or the Pass Through Trustee, waive the Regulatory Event of Loss or Burdensome Buyout Event that gave rise to the right to purchase the Owner Participant’s Beneficial Interest or the membership interest in the

Owner Participant, as the case may be, and the Facility Lease shall continue in full force and effect in accordance with its terms.

SECTION XVIII MISCELLANEOUS

Section 18.1. Consents. The Owner Participant covenants and agrees that it shall not unreasonably withhold its consent to any consent requested of the Owner Lessor under the terms of the Operative Documents that by its terms is not to be unreasonably withheld by the Owner Lessor.

Section 18.2. Successor Owner Lessor. The parties hereto agree that the transfer or assignment pursuant to the terms of the Trust Agreement by the Owner Lessor to a successor Owner Lessor, pursuant to the trust created thereunder, will not violate the terms of any Operative Document.

Section 18.3. Bankruptcy of Trust Estate. If (a) all or any part of the Trust Estate becomes the property of a debtor subject to the reorganization provisions of Title 11 of the United States Code, as amended from time to time, (b) pursuant to such reorganization provisions the Owner Participant is 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 (c) the Lease Indenture Trustee actually receives any Excess Amount, as defined below, which reflects any payment by the Owner Participant on account of Section 18.3(b), the Lease Indenture Trustee shall promptly refund to the Owner Participant such Excess Amount. For purposes of this Section 18.3, “Excess Amount” means the amount by which such payment exceeds the amount which would have been received by the Lease Indenture Trustee if the Owner Participant had not become subject to the recourse liability referred to in Section 18.3(b). Nothing contained in this Section 18.3 shall prevent the Lease 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 Section 18.3(b)).

Section 18.4. 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 party hereto.

Section 18.5. Notices. Unless otherwise expressly specified or permitted by the terms hereof, all communications and notices provided for herein shall be in writing or by a telecommunications device capable of creating a written record, and any such notice shall become effective (a) upon personal delivery thereof, including, without limitation, by overnight mail or courier service, (b) in the case of notice by United States mail, certified or registered, postage prepaid, return receipt requested, upon receipt thereof, or (c) in the case of notice by such a telecommunications device, upon transmission thereof, provided such transmission is promptly confirmed by either of the methods set forth in Sections 18.5(a) or (b) above, in each case addressed to each party hereto at its address set forth below or, in the case of any such party hereto, at such other address as such party may from time to time designate by written notice to the other parties hereto:

Section 18.12. Limitation of Liability.

(a) None of the Owner Participant, the Owner Lessor, the Owner Trustee, the Trust Company, the Lease Indenture Company, the Lease Indenture Trustee, the Pass Through Trustee or the Pass Through Company shall have any obligation or duty to Midwest, NRG or to others with respect to the transactions contemplated hereby, except those obligations or duties expressly set forth in this Agreement and the Operative Documents, and neither the Owner Lessor, the Owner Participant, the Owner Trustee, the Trust Company, the Lease Indenture Company, the Lease Indenture Trustee, the Pass Through Trustee or the Pass Through Company shall be liable for performance by any other party hereto of such other party’s obligations or duties hereunder. Without limitation of the generality of the foregoing, under no circumstances whatsoever shall the Owner Participant be liable to Midwest, NRG, the Lease Indenture Trustee, the Pass Through Trustee or the Pass Through Company for any action or inaction on the part of the Owner Lessor or the Owner Trustee in connection with the transactions contemplated herein, whether or not such action or inaction is caused by willful misconduct or gross negligence of the Owner Lessor, unless such action or inaction is at the written direction of the Owner Participant.

(b) The Trust Company is executing the Operative Documents to which it is a party solely as trustee under the Trust Agreement and not in its individual capacity, except as expressly provided herein or therein, and in no case whatsoever shall the Trust Company be personally liable for, or for any loss in respect of, any of the statements, representations, warranties, agreements or obligations of the Owner Lessor or the Owner Trustee hereunder or under any other Operative Document, as to all of which the other parties hereto agree to look solely to the Trust Estate; provided, however, that the Trust Company shall be liable hereunder for its own gross negligence or willful misconduct or for a breach of its representations, warranties and covenants made in its individual capacity.

(c) The Lease Indenture Company and the Pass Through Company are each entering into the Operative Documents to which they are parties solely as trustees under the Lease Indenture and the Pass Through Trust Agreement, respectively, and not in their individual capacities, except as expressly provided herein or therein, and in no case whatsoever shall the Lease Indenture Company or the Pass Through Company be personally liable for, or for any loss in respect of, any of the statements, representations, warranties, agreements or obligations of the Owner Lessor hereunder or under any other Operative Document, as to all of which the other parties hereto agree to look solely to the Trust Estate and the Indenture Estate; provided, however, that such party shall be liable hereunder for its own gross negligence, willful misconduct, bad faith or a breach of its representations, warranties and covenants made in its individual capacity.

(d) The right of the Lease Indenture Company or the Pass Through Company to perform any discretionary act enumerated herein or in any other Operative Document (including, without limitation, the right to consent to any action which requires its consent and the right to waive any provision of, or consent to any change or amendment to, any of the Operative Documents) shall not be construed as a duty, and neither the Lease Indenture Company nor the Pass Through Company shall be accountable or liable for other than its gross negligence, willful misconduct or bad faith in the performance or non-performance of such acts. In connection with any such discretionary acts, the Lease Indenture Trustee may in its own judgment (but shall not, except as otherwise provided in the Lease Indenture or as otherwise required by Requirement of Law, have any obligation to) request in writing the approval of the Pass Through Trustee as holders of Lessor Notes and each Pass Through Trustee may in its sole discretion (but shall not, except as otherwise provided for in the Operative Documents or as otherwise required by Requirement of Law, have any obligation to) request the approval of the holders of the Certificates.

(e) The Owner Participant will give Midwest and NRG at least fifteen (15) days’ prior notice of any proposed amendment or supplement to the Trust Agreement (other than amendments solely effecting a transfer of the Owner Participant’s interest in the Trust Estate or with respect to administrative matters) and deliver true, complete and fully executed copies to Midwest and NRG of any amendment or supplement to the Trust Agreement. No amendment or supplement to the Trust Agreement that could materially adversely affect the interests of the Lease Indenture Trustee or the Pass Through Trustee shall become effective without the prior written consent of the Lease Indenture Trustee or the Pass Through Trustee, as applicable.

(f) Nothing in this Participation Agreement modifies the release or exculpation provisions in the Chapter 11 Plan.

Section 18.13. Consent to Jurisdiction; Waiver of Trial by Jury, Process Agent.

(a) Each of the parties hereto (i) hereby irrevocably submits to the nonexclusive jurisdiction of the Supreme Court of the State of New York, New York County (without prejudice to the right of any party to remove to the United States District Court for the Southern District of New York) and to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York for the purposes of any suit, action or other proceeding arising out of this Agreement, the other Operative Documents, or the subject matter hereof or thereof or any of the transactions contemplated hereby or thereby brought by any of the parties hereto or their successors or assigns; (ii) hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such New York State court, or in such federal court; and (iii) to the extent permitted by Requirement of Law, hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding any claim that it is not personally subject to the jurisdiction of the above-named courts, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement, the other Operative Documents, or the subject matter hereof or thereof may not be enforced in or by such court.

(b) TO THE EXTENT PERMITTED BY REQUIREMENT OF LAW, EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES THE RIGHT TO DEMAND A TRIAL BY JURY, IN ANY SUCH SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF THIS AGREEMENT, THE OTHER OPERATIVE DOCUMENTS, OR THE SUBJECT MATTER HEREOF OR THEREOF OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY BROUGHT BY ANY OF THE PARTIES HERETO OR THEIR SUCCESSORS OR ASSIGNS.

(c) By the execution and delivery of this Agreement, Midwest and NRG designate, appoint and empower CT Corporation System as their authorized agent to receive for and on their behalf service of any summons, complaint or other legal process in any such action, suit or proceeding in the State of New York for so long as any obligation of Midwest and NRG shall remain outstanding hereunder or under any of the other Operative Documents. Midwest and NRG shall grant an irrevocable power of attorney to CT Corporation System in respect of such appointment and shall maintain such power of attorney in full force and effect for so long as any obligation of Midwest and NRG shall remain outstanding hereunder or under any of the Operative Documents.

Section 18.14. Further Assurances. Each party hereto will promptly and duly execute and deliver such further documents to make such further assurances for and take such further action reasonably requested by any party to whom such first party is obligated, all as may be reasonably necessary to carry out more effectively the intent and purpose of this Agreement and the other Operative Documents.

Section 18.15. Effectiveness. This Agreement has been dated as of the date first above written for convenience only. This Agreement shall be effective on the date of execution and delivery by each of the parties hereto.

Section 18.16. Measuring Life.

Section 18.17. No Partnership, Etc. The parties hereto intend that nothing contained in this Agreement or any other Operative Document shall be deemed or construed to create a partnership, joint venture or other co-ownership arrangement by and among any of them.

Section 18.18. Restrictions on Transfer of Membership Interest.

(a) No OP Member shall, during the Facility Lease Term, assign, convey or transfer any of its right, title or interest in the Membership Interest or cause the Owner Participant to issue additional membership interests without the prior written consent of Midwest and NRG and, for so long as the Lien of the Lease Indenture has not been terminated or discharged, the Lease Indenture Trustee and the Pass Through Trustee; provided, however, that an OP Member may assign, convey or transfer all or any part of its interest in the Membership Interest without such consent to a Person (the “Member Transferee”), if the Owner Participant Guaranty shall remain outstanding and in full force and effect or each of the following conditions shall have been satisfied:

(b) the Member Transferee shall be either (A) an Affiliate of the Owner Participant which does not otherwise qualify under clause (B) below provided the Owner Participant Guaranty shall remain in full force and effect, or (B) a Person which guarantees all of the Owner Participant’s obligations under the Operative Documents pursuant to a guaranty substantially in the form of Exhibit Y to the Original Participation Agreement and meets the following criteria: (1) the tangible net worth of the Member Transferee is at least equal to $75 million calculated in accordance with GAAP; and (2) unless waived by Midwest and NRG, and so long as no Material Lease Default or Lease Event of Default shall have occurred and be continuing, such Member Transferee is not a Competitor (as defined in Section 10.1(e)) of, or in material litigation with, Midwest or any Affiliate of Midwest;

(d) the Member Transferee agrees in the guaranty or in another written instrument reasonably acceptable to Midwest and, for so long as the Lien of the Lease Indenture has not been terminated or discharged, the Lease Indenture Trustee and the Pass Through Trustee to be bound by this Section 18.18 and by provisions of Section 18.19 of this Agreement.

(e) Neither the Facility Lessee nor NRG shall not be responsible for any adverse tax consequence to the Owner Lessor, the Owner Participant or the Guarantor resulting from any transfer pursuant to this Section 18.18 and the Pricing Assumptions shall not be changed as a result of any such transfer.

(f) The OP Member shall give the Owner Lessor, the Owner Trustee, the Lease Indenture Trustee, the Pass Through Trustee, Midwest and NRG thirty (30) days prior written notice of such transfer, or ten (10) days in the case of a transfer to an Affiliate of the Owner Participant, specifying the name and address of any proposed Member Transferee and such additional information as shall be necessary to determine whether the proposed transfer satisfies the requirements of this Section 18.18. If requested by the OP Member, the Owner Participant, the Lease Indenture Trustee or the Pass Through Trustee, Midwest or NRG shall acknowledge qualifying transfers. All reasonable fees, expenses and charges of the Lease Indenture Trustee, the Pass Through Trustee, Midwest and NRG (including reasonable attorneys’ fees and expenses in connection with any such transfer or proposed transfer), including any of the foregoing relating to any amendments to the Operative Documents required in connection

therewith, shall be paid by the OP Member, without any right of indemnification from Midwest, NRG, the Lease Indenture Trustee, the Pass Through Trustee or any other Person; provided, however, that the OP Member shall have no obligation to pay fees, expenses or charges of Midwest and NRG as a result of any transfer while a Material Lease Default or a Lease Event of Default is continuing, in which case Midwest or NRG shall be obligated to pay such costs.

(g) Upon any transfer to a Member Transferee specified in clause (a)(i)(B) of this Section 18.18 and compliance with all of the other provisions of this Section 18.18, (i) the Member Transferee shall, to the extent of the Membership Interest conveyed to the Member Transferee, be deemed an “OP Member” for purposes of this Section 18.18 and the Person executing the guaranty pursuant to such clause (a)(i)(B) shall be deemed a “OP Guarantor” for all purposes and each reference in this Agreement and each other Operative Document to the “OP Guarantor” shall thereafter be deemed to include such Member Transferee or the Person executing such guaranty, as the case may be, to the extent of the obligations expressly transferred to the Member Transferee and guaranteed by such Person, for all purposes and (ii) the existing OP Guarantor shall be released from all obligations under its Owner Participant Guaranty to the extent such obligations are expressly guaranteed by the Member Transferee or such Affiliate; provided, however, that in no event shall any such transfer waive or release the existing OP Guarantor from any liability existing immediately prior to or occurring simultaneously with such transfer. Except as expressly provided in the immediately preceding sentence, no transfer of any Membership Interest shall effect the obligations of the existing OP Guarantor under the Owner Participant Guaranty or any other OP Guarantor under its Owner Participant Guaranty.

(h) Notwithstanding anything herein to the contrary, any transfer of Membership Interest pursuant to this Section 18.18 shall be subject to Midwest’s right of first offer and right of first refusal set forth in Sections 16.1 and 16.2 of this Agreement, respectfully, to the same extent as if such transfer were a transfer by the Owner Participant of its Beneficial Interest.

Section 18.19. [RESERVED].

Section 18.20. Guaranteed TV Amount. Each party to this Agreement acknowledges notice of, and consents in all respects to, the terms of the NRG Guarantee, including Section 2.03 of the NRG Guarantee which limits obligations of NRG under the NRG Guarantee in certain specific instances to the Guaranteed TV Amount.
