Section 2.2. Closing Date; Procedure for Closing.

(a) Closing Date. The closing of the transactions contemplated hereby (the “Closing”) shall take place after 12:00 noon, New York City time, on the Scheduled Closing Date or such other date as the parties hereto shall mutually agree (the “Closing

	Date”), at the offices of Akin Gump Strauss Hauer & Feld LLP located at 590 Madison Avenue, New York, New York 10022, or at such other place as the parties hereto shall mutually agree.

	(b) Procedures for Funding. Unless the Closing Date shall have been postponed pursuant to Section 2.2(c), subject to the terms and conditions of this Participation Agreement, the Owner Participant shall make the Owner Participant’s Commitment available not later than 12:00 noon, New York City time, on the Scheduled Closing Date, by transferring or delivering such amount, in funds immediately available on such Scheduled Closing Date, to the Trust Company in New York, New York. All funds made available pursuant to this Section 2.2(b) will be held by the Trust Company in trust for the Owner Participant and shall not be part of the Indenture Estate or the Trust Estate, shall be invested by the Trust Company in accordance with Section 2.2(d) below and such funds shall remain the sole property of the Owner Participant unless and until released by the Owner Participant and made available to the Lessor and applied to pay the Purchase Price or Transaction Expenses or returned to the Owner Participant, as provided in this Agreement.

	(c) Postponement of the Closing. The Scheduled Closing Date may be postponed from time to time for any reason if the Lessee gives the Owner Participant, the Lessor, the Owner Trustee, the Indenture Trustee and the Pass Through Trustee a facsimile or telephonic (confirmed in writing) notice of such postponement and notice of the date to which the Closing has been postponed, such notice of postponement to be received by each party no later than noon, New York City time, on the Business Day immediately preceding the Scheduled Closing Date. If, prior to receipt of a postponement notice under this Section 2.2(c), the Owner Participant shall have provided funds in accordance with Section 2.2(b), such funds shall be returned to the Owner Participant, as soon as reasonably practicable but in no event later than the Business Day following the date of such notice, unless the Owner Participant shall have otherwise directed.

	(d) Investment of Funds. If, on or prior to the Scheduled Closing Date, the Owner Participant has made the Owner Participant’s Commitment available to the Trust Company in accordance with Section 2.2(b), the Closing does not occur on such date and the Trust Company is unable to return such funds to the Owner Participant on such date, the Trust Company shall, subject to Section 2.2(b) above, use reasonable efforts to invest such funds from time to time at the written direction of the Lessee, and at the Lessee’s sole expense and risk, in Permitted Investments described in clause (h) of the definition thereof until such funds can be returned to the Owner Participant. If, on or prior to the Scheduled Closing Date, the Owner Participant has made the Owner Participant’s Commitment available to the Trust Company in accordance with Section 2.2(b), the Closing does not occur on such date and the Trust Company has not returned such funds to the Owner Participant by 2:00 p.m., New York City time, on such date, then the Lessee shall reimburse the Owner Participant for loss of the use of such funds at the Applicable Rate for each day, from and including the Scheduled Closing Date to, but excluding the

	earlier of, (i) the day that such funds have been returned to the Owner Participant pursuant to Section 2.2(c) (funds received by the Owner Participant after 2:00 p.m., New York City time, on any day shall be deemed to be returned on the next succeeding Business Day) and (ii) the Closing Date. Subject to payment for the account of the Owner Participant of any reimbursement for loss of use of funds due to it at the Applicable Rate, any net gain realized on the investment of such funds (including interest) to the extent actually received by the Trust Company shall be paid to the Lessee by the Trust Company on the earlier of (A) the date such funds are returned to the Owner Participant pursuant to Section 2.2(c) and (B) the Closing Date. The Trust Company shall not be liable for any interest on or loss resulting from such investments and, if such funds are made available to the Lessor and utilized to pay the Purchase Price or Transaction Expenses on the Closing Date, the Lessee shall reimburse the Lessor for any net loss realized on the investment of such funds. If such funds are not so utilized, the Lessee shall, in addition to its obligation to reimburse the Owner Participant for loss of use as provided above, reimburse the Owner Participant on the date such funds are returned to the Owner Participant for any net loss realized on the investment of such funds. In order to obtain funds for payment of the Purchase Price or Transaction Expenses or to return funds made available to the Trust Company by the Owner Participant, the Trust Company is authorized, at the direction of the Owner Participant, to sell any investments or obligations purchased as aforesaid.

	(e) Expiration of Commitments. The obligation of the Owner Participant to make its Equity Investment shall expire at 5:00 p.m., New York City time, on September 30, 2007. If the Closing Date has not occurred on or before such date the Transaction Parties shall have no obligation to consummate the transactions contemplated under this Agreement and, except as provided in Sections 2.3, 9.1 and 9.2, all obligations of the Transaction Parties shall cease and terminate.

Section 2.3. Transaction Expenses.

(a) If the Overall Transaction is consummated, (i) the Lessor agrees to promptly pay all Transaction Expenses upon receipt of detailed invoices (provided that legal bills may be redacted to preserve attorney-client privilege) (or, with respect to Transaction Expenses payable by the Lessor that have previously been paid by the Lessee with the consent of the Owner Participant, the Lessor agrees to reimburse the Lessee therefor promptly upon request by the Lessee); provided, however, that in no event shall the Lessor be obligated to pay any portion of such Transaction Expenses to the extent that the payment of such portion would cause the aggregate amount of all such Transaction Expenses paid by the Lessor to exceed an amount equal to the Lessor Expense Cap. If the aggregate amount of Transaction Expenses exceeds the Lessor Expense Cap, the Lessor and the Lessee shall cooperate in good faith to allocate the Transaction Expenses with the intention that, to the maximum extent possible, the Lessee pays only those expenses properly attributable to the Lessee; provided, however, that the Lessor shall not pay any Transaction Expenses in excess of the Lessor Expense Cap.

	(b) If the Overall Transaction is not consummated for any reason (including as a result of the Lessee electing not to close the Overall Transaction pursuant to Section 12.1), then the Lessee shall pay all Transaction Expenses upon receipt of detailed invoices; provided, however, that the Lessee shall not be obligated to pay the out-of-pocket expenses of the Lessor and the Owner Participant (which out-of-pocket expenses do not include the fees and expenses of the Appraiser, the Engineering Consultant, Thorndike Landing LLC, Arcadis, MPR Associates, Inc., the Environmental Consultant and Insurance Consultant) or the legal fees and expenses of their counsel if the Overall Transaction is not consummated due to a failure of the Owner Participant to negotiate in good faith or to have obtained its internal approvals for reasons other than arising out of its due diligence review of the Lease Transaction, the Generating Station, the Lessee and the Guarantor.

	(c) Following the Closing Date, the Lessee will be responsible for, and will pay as Supplemental Rent on an After-Tax Basis to the Owner Participant, the annual administration fees, if any, and expenses (including reasonable and documented fees and expenses of its outside counsel) of the Trust Company (in its individual capacity or as Owner Trustee), the Account Bank, the Indenture Trustee and the Pass Through Trustee.

SECTION 3. REPRESENTATIONS AND WARRANTIES

Section 3.1. Representations and Warranties of the Lessee.

The Lessee represents and warrants that, except as set forth in the applicable section of the disclosure schedule attached hereto as Schedule 3.1 (the “Lessee Disclosure Schedule”), as of the date of execution and delivery hereof and as of the Closing Date:

	(a) Organization, Good Standing. The Lessee is a corporation duly organized, validly existing and in good standing under the laws of the State of Ohio. The Lessee is duly qualified to do business in each other jurisdiction where the nature of its business requires such qualification other than any such jurisdiction where the failure to be so qualified would not result in a Material Adverse Effect. The Lessee has all requisite power and authority to own its assets, conduct its business and execute, deliver and perform its obligations under the Lessee Documents.

	(b) Lessee Documents. With respect to its obligations under the Lessee Documents:

	(i) The Lessee has taken all action required for the due execution, delivery and performance of the Lessee Documents;

	(ii) The Lessee’s obligations under the Lessee Documents are legal, valid, binding and enforceable, except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar Applicable

	Laws affecting the rights of creditors generally and by general principles of equity; and

	(iii) The execution, delivery and performance of the Lessee Documents does not (a) result in any breach of its certificate of incorporation or by-laws or any material agreement, contract or instrument to which the Lessee is a party or by which any of its property or assets is bound, (b) conflict with any Applicable Law which reasonably would be expected to result in a Material Adverse Effect, or (c) result in the creation of any Lien (with the exception of Permitted Liens) upon any of the property or assets of the Lessee pursuant to the terms of any indenture, mortgage, deed of trust, credit agreement or any other material agreement, contract or instrument to which the Lessee is a party or by which any of its property or assets is bound.

(c) Governmental Approvals. All Permits which are required to be obtained (as of the date this representation is made or deemed to be made) (1) by the FirstEnergy Parties in connection with the execution and delivery of, or performance of the transactions contemplated by, this Agreement, the other Operative Documents and the Operating Agreement, (2) to the Actual Knowledge of Lessee with respect to the participation by the Owner Participant, the OP Guarantor and the Lessor in the transactions contemplated by this Agreement and the other Operative Documents, and (3) in connection with (i) the operation and maintenance of the Facility and the Ancillary Facilities, (ii) the issuance of the Pass Through Certificates and the execution, delivery and performance by the Lessee of the Lessee Documents, and (iii) the leasing of the Undivided Interest, have been obtained, were validly issued and are in full force and effect on the date hereof. A list of all such Permits is set forth on Part I of Schedule 4.5 hereof (all such Permits, including those set forth on Part II of Schedule 4.5 hereof, collectively, the “Governmental Approvals”). The Lessee has received uncontested FERC orders authorizing the Facility Lease pursuant to Section 203 of the FPA and all Governmental Approvals that have been obtained pursuant to the first sentence of this Section 3.1(c) are final and any period for the filing of notice of rehearing or application for judicial review of the issuance of each such Governmental Approval has expired without any such notice or application having been made (in each case, other than those for which the failure to be final would not have a Material Adverse Effect). No such Governmental Approval is the subject of any pending or, to the Actual Knowledge of the Lessee, threatened judicial or administrative proceeding, which judicial review or proceeding could have a Material Adverse Effect. Each FirstEnergy Party is in compliance with all Governmental Approvals required to be obtained by it as of the date this representation is made or deemed to be made unless such noncompliance could not reasonably be expected to result in a Material Adverse Effect. The Lessee does not have any reason to believe that it will be unable to obtain the Governmental Approvals that are not required to be obtained prior to the date this representation is made or deemed to be made, which Governmental Approvals are set forth on Part II of Schedule 4.5, in the ordinary course of business and at such time or times as may be necessary to avoid any

	substantial delay in, or material impairment to, the performance of the transactions as contemplated by the Operative Documents and the Operating Agreement.

	(d) Litigation. There are no actions, suits, investigations or proceedings at law or in equity by or before any Governmental Entity pending against the Lessee or, to its Actual Knowledge, threatened against the Lessee, or any property or other assets or rights of the Lessee or with respect to any Operative Document, the Operating Agreement, the Generating Station, the Facility or the Undivided Interest which (i) questions the validity of the Operative Documents or the ability of the Lessee to perform its obligations under the Lessee Documents or (ii) if determined adversely to it, would reasonably be expected to result in a Material Adverse Effect.

	(e) Taxes.

Section 6.4. Transfer of the Lessor’s Interest.

SECTION 7. COVENANTS OF THE OWNER PARTICIPANT

Section 7.1. Restrictions on Transfer of Trust Interest.

(a) The Owner Participant covenants and agrees that it shall not during the Lease Term assign, convey or transfer any of its right, title or interest in the Trust Interest without the prior written consent of the Lessee and, so long as the Lien of the Indenture has not been terminated or discharged, the Indenture Trustee; provided, however, that the Owner Participant may, subject to Section 7.6, assign, convey or transfer all, but not less than all, of the Trust Interest without such consent to a Person (the “Transferee”) which shall assume the duties and obligations of the Owner Participant under the Operative Documents with respect to the interest being transferred pursuant to an OP Assignment and Assumption Agreement substantially in the form of Exhibit J hereto, if each of the following conditions shall have been satisfied on or prior to such transfer:

	(i) the Lessee and, so long as the Lien of the Indenture has not been terminated or discharged, the Indenture Trustee and the Pass Through Trustee shall have received an opinion(s) of counsel (including an opinion with respect to a guaranty pursuant to clause (iii) of this Section 7.1(a), if applicable), which opinion(s) and counsel are reasonably satisfactory to each such recipient, to the effect that, subject to customary qualifications and exceptions, such transfer will not violate any Applicable Laws;

	(ii) the Transferee shall be a “United States person” within the meaning of Section 7701(a)(30) of the Code;

	(iii) the Transferee shall be either (A) an Affiliate of the transferor Owner Participant; provided that, if the Transferee does not qualify under clause (B) below, all of the payment obligations of the Transferee with respect to the interest being transferred under the Operative Documents shall be guaranteed by the transferor Owner Participant, or a Person then providing a guaranty of the transferor Owner Participant’s payment obligations hereunder, pursuant to an OP Parent Guaranty, or (B) a Person which meets, or the payment obligations of which with respect to the interest being transferred under the Operative Documents are guaranteed (pursuant to an OP Parent Guaranty) by a Person (the transferor Owner Participant or such other guarantor, the “Transferee Guarantor”)

	which meets, the following criteria: the tangible net worth or capital and surplus of the Transferee or Transferee Guarantor for its most recent fiscal quarter is at least $75 million calculated in accordance with GAAP; and

	(iv) unless waived in writing by the Lessee prior to such transfer, such Transferee which qualifies under clause (iii)(B) above is not a Competitor of, or in material litigation with, the Lessee or any Affiliate of the Lessee.

	Notwithstanding the foregoing, the restrictions set forth in Section 7.1 shall not inure to the benefit of the Lessee if such transfer occurs during the continuance of a Material Default or Lease Event of Default.

(b) For purposes of Section 7.1(a)(iv), a “Competitor” shall be an entity which at the time of the transfer is, or whose Affiliate is, engaged as a seller, marketer, trader, aggregator or generator of electric capacity or energy within the geographic area of the regional transmission organizations, or their equivalent, in which the Guarantor or any Affiliate thereof participates; provided that, a Competitor shall not include a bank, an insurance company or other financial institution or an Affiliate of any thereof in each case not owned by (i) an entity that owns and actually operates on a daily basis a fleet of power plants with capacity of 500 MW or greater, which power plants sell the majority of their energy into a competitive market (other than under long-term contracts) that the Guarantor operates in and competes directly with one or more of the Guarantor’s power stations in (such entity an “IPP”), (ii) the ultimate parent of an electric utility company or IPP or (iii) an ultimate parent whose principal or a substantial part of whose business is that of an electric utility company or IPP. For the avoidance of doubt, a Competitor shall not under any circumstances include banks, insurance companies or financial institutions or their Affiliates that would otherwise be a Competitor as a result of the operation of clause (i), (ii) or (iii) of the preceding sentence that are generally in the business of making passive investments or are not involved in the day-to-day decisions regarding plant dispatch and bidding strategies with respect to the power plants they own and operate. In addition, the Lessee will have the right to prepare and provide to the Owner Participant on the Closing Date a list of entities which shall be ineligible to qualify as a Transferee, provided that each such listed entity either (A) has publicly announced an intent or taken material steps to become a Competitor of the Lessee or its Affiliates and is not otherwise deemed to have been a Competitor pursuant to the proviso in the second preceding sentence, or (B) is a lessor or an owner participant in respect of a lease to the Lessee of an interest in the Generating Station that has taken, or failed to take, any action the result of which is materially adverse to the Lessee or any of its Affiliates and is inconsistent with the actions taken or not taken by at least 67% of other similarly situated lessors or owner participants; provided that the list shall at no time include more than three entities described in this clause (B) and the list may not include the Lessor, the Other Lessors, the Owner Participant and the Other Owner Participants or their Affiliates. The Lessee shall have the right to update such list (such updated list to replace the previous list) not more frequently than annually, commencing on the first anniversary of the Closing Date.

	(c) During such time as a Material Default or Lease Event of Default shall have occurred and be continuing the foregoing restrictions (other than clauses (a)(ii) and (a)(iii) above for so long as the Notes are outstanding) shall not apply.

	(d) The Lessee shall not be responsible for any adverse Tax consequence to the Lessor or the Owner Participant resulting from any transfer pursuant to this Section 7.1 (unless such transfer occurs while a Lease Event of Default is continuing) and the Pricing Assumptions shall not be changed as a result of any such transfer.

	(e) The Owner Participant shall give the Indenture Trustee and, so long as no Material Default or Lease Event of Default shall have occurred and be continuing, the Lessee 15 Business Days’ prior written notice of such transfer, or five Business Days’ prior written notice in the case of a transfer to an Affiliate of the Owner Participant, specifying the name and address of any proposed Transferee and such additional information as shall be necessary to determine whether the proposed transfer satisfies the requirements of this Section 7.1. The Lessee will promptly after receipt of such notice acknowledge to the Owner Participant and the Indenture Trustee if all of the requirements to the proposed transfer have been or will be met. If the Lessee fails to provide such acknowledgment within 15 Business Days or (in the case of a transfer to an Affiliate of the Owner Participant) five Business Days after receipt of such notice, the Lessee shall be deemed to have given such acknowledgement.

	(f) All reasonable fees, expenses and charges of the Indenture Trustee, the Pass Through Trustee, and the Lessee (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 on an After-Tax Basis by the Owner Participant, without any right of indemnification from the Lessee or any other Person; provided, however, that the Owner Participant shall have no obligation to pay fees, expenses or charges of the Lessee in connection with any transfer while a Material Default or a Lease Event of Default is continuing, in which case the Lessee shall be obligated to pay such costs.

	(g) Upon any such transfer in compliance with this Section 7.1, (i) such Transferee shall (A) be deemed the “Owner Participant” for all purposes, and (B) enjoy the rights and privileges and perform the obligations of the Owner Participant hereunder and under each of the OP Assignment and Assumption Agreement, the OP Parent Guaranty and each other Operative Document to which such Owner Participant is a party, and each reference in this Agreement, the OP Parent Guaranty and each other Operative Document to the “Owner Participant” shall thereafter be deemed a reference to such Transferee for all purposes and (ii) subject to clause (a)(iii) above, the transferor Owner Participant and the OP Guarantor, if any, of such transferor Owner Participant’s obligations shall be released from all obligations hereunder and under each other Operative Document to which such transferor or OP Guarantor is a party or by which such transferor Owner Participant or OP Guarantor is bound to the extent such obligations are expressly assumed by a Transferee or in respect of whose payment

	obligations are guaranteed by a Transferee Guarantor meeting the requirements of this Section 7.1; provided, however, that in no event shall any such transfer be deemed to result in a waiver or release of the transferor or its OP Guarantor from any liability accruing or existing in respect of any period occurring on or prior to or occurring simultaneously with such transfer.

	(h) The transfer restrictions set forth in Section 7.1 (other than the requirement that the Owner Participant and the Transferee enter into an OP Assignment and Assumption Agreement) shall also apply to any transfer of the equity ownership interests of an Owner Participant which has as its sole (or substantially equivalent to sole) business activity its participation in the transactions contemplated by the Operative Documents. In the case of such a transfer of equity ownership interests which satisfies such restrictions of this Section 7.1, the Owner Participant’s obligations under the Operative Documents shall continue, but the Owner Participant shall, except in the case of a transfer to a transferee described in clause (a)(iii)(A) above, procure a new OP Parent Guaranty from a guarantor meeting the requirements of clause (a)(iii)(B) above.

Section 7.2. Owner Participant’s Liens. The Owner Participant covenants that it will not directly or indirectly create, incur, assume or suffer to exist any Owner Participant’s Lien and the Owner Participant shall promptly notify the Lessee and, so long as the Lien of the Indenture has not been terminated or discharged, the Indenture Trustee of the imposition or existence of any such Lien of which the Owner Participant has Actual Knowledge and shall promptly, at its own expense, take such action as may be necessary to duly discharge such Owner Participant’s Lien.

Section 7.3. Amendments or Revocation of Trust Agreement. Notwithstanding anything to the contrary contained in the Trust Agreement, the Owner Participant covenants that during the Lease Term it will not (a) amend, supplement, or otherwise modify Section 8.01, 10.01, 10.02 or 10.03 of the Trust Agreement without the prior written consent of the Lessee so long as no Material Default or Lease Event of Default has occurred and is continuing, and without the prior written consent of the Indenture Trustee so long as the Lien of the Indenture has not been terminated or discharged, or (b) revoke, or otherwise waive compliance with or terminate the Trust Agreement without the prior written consent of the Lessee so long as no Material Default or Lease Event of Default has occurred and is continuing, and the Indenture Trustee so long as the Lien of the Indenture has not been terminated or discharged.

Section 7.4. Bankruptcy Filings. The Owner Participant agrees that it will not file a petition, or join in the filing of a petition, seeking reorganization, arrangement, adjustment or composition of, or in respect of, the Lessor under the Bankruptcy Code, or any other Applicable Law.

Section 7.5. Instructions. The Owner Participant agrees that it will not instruct the Lessor to take any action that the Lessor is prohibited from taking by this Agreement or any other Operative Document.

Section 7.6. Right of First Refusal. In the event the Owner Participant desires to sell, convey or otherwise transfer (including, without limitation, by means of a lease that is substantially

	equivalent economically to a sale) its Trust Interest, or cause the Lessor to sell all or substantially all of the Lessor’s Interest (each a “Sale”), upon or at any time during the three year period following the Date of Return of the Undivided Interest to any Person other than an Affiliate of the Owner Participant, or in the relevant circumstances described in Section 10, 13 or 14 of the Facility Lease, any such Sale shall, unless such sale, conveyance or transfer is in connection with the exercise of remedies upon a Lease Event of Default, be subject to the Lessee’s right of first refusal on the terms and conditions set forth in this Section 7.6. The Owner Participant shall give the Lessee prompt written notice of all bona fide offers for a Sale that have been received from any other Person that it wishes to accept, together with a statement of the price and all of the material terms, conditions and provisions contained in such offers for a Sale. The Lessee shall have the right within a period of 45 days from and after its receipt of such notice (the “Notice Period”) to notify the Owner Participant of its intent to exercise its right of first refusal with respect to a Sale; provided that the Lessee shall provide to the Owner Participant’s reasonable satisfaction evidence of the Lessee’s ability to pay the price and all other amounts that the Lessee will be obligated to pay in connection with such Sale. If the Lessee elects to exercise the right provided in the preceding sentence, it will within 45 days of its notice (the “Agreement Period”) execute a contract on terms and conditions not materially less favorable to it than the terms and conditions, taken as a whole, as the offer giving rise to such right and thereafter proceed to consummate such contract in accordance with its terms; provided, however, that in the case of a Sale pursuant to Section 10, 13 or 14 of the Facility Lease the purchase price shall not be less than the amount of the Qualifying Cash Bid. If the Lessee does not give such notice to the Owner Participant within the Notice Period or execute such a contract within the Agreement Period and thereafter proceed to consummate such contract in accordance with its terms, the Owner Participant will be free to proceed under the terms and conditions of the bid set forth in its notice to the Lessee, unless the failure to execute the contract with the Lessee within the Agreement Period or thereafter consummate such contract in accordance with its terms is attributable to the failure of the Owner Participant to negotiate or otherwise act in good faith or a breach by the Owner Participant of its obligations under such contract. In the event that the terms of the bid are revised in any way that changes the offer or agreement for the Sale, such that the terms of the Sale are materially less favorable to the Owner Participant (it being understood and agreed that any reduction in the price or a change in the terms of payment thereof in a manner beneficial to the potential purchaser shall be deemed to be materially less favorable to the Owner Participant), the Owner Participant shall again comply with the notice and right of first refusal provisions of this Section 7.6 prior to accepting such revised offer or entering into such revised agreement; provided that, for such revised offer or agreement, the Notice Period shall be ten Business Days from the date of such new notice, and the Agreement Period shall not exceed 45 days from the date of the Lessee’s notice accepting such new terms.

	(b) Upon the closing of any Sale to the Lessee, the Lessee (or its successor or permitted assign) shall have the same rights as a Transferee under Section 7.1(g) hereof,

and the Owner Participant and the OP Guarantor, if any, shall be released from all obligations hereunder and under each other Operative Document except as provided in Section 7.1(g).

Section 7.7. Appointment of Successor Owner Trustee. Notwithstanding any other provision of this Agreement, a successor Owner Trustee shall not be appointed by the Owner Participant without the consent of the Lessee and, so long as the Lien of the Indenture has not been terminated or discharged, the Indenture Trustee unless (a) such successor Owner Trustee (i) meets the requirements of the Trust Agreement, and (ii) has a combined capital and surplus of at least $150 million, and (b) the Lessee and, so long as the Lien of the Indenture has not been terminated or discharged, the Indenture Trustee shall have received such documentation, including opinions of counsel, reasonably satisfactory to the Lessee or the Indenture Trustee, as the case may be, as they may request.

SECTION 8. COVENANTS OF THE INDENTURE TRUSTEE AND THE PASS THROUGH TRUSTEE

Section 8.1. Indenture Trustee’s Liens. Neither the Indenture Company nor the 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 Owner Trustee, the Lessor and the Lessee of the imposition of any such Lien of which it has Actual Knowledge and shall promptly (and in any event within 30 days of obtaining Actual Knowledge of such Lien), at its own expense, take such action as may be necessary to duly discharge such Indenture Trustee’s Lien.

Section 8.2. Pass Through Trustee’s Covenant Not to Transfer Notes. The Pass Through Trustee agrees that it will not transfer any Note (or any part thereof) to any entity (except to a successor Pass Through Trustee appointed pursuant to the terms of the Pass Through Trust Agreement) until it receives from such entity a certification which makes a representation and warranty as of the date of such transfer that no part of the funds to be used by it for the purchase and holding of such Note (or any part thereof) constitutes assets of any Plan or that such purchase and holding will be covered by a prohibited transaction class exemption issued by the U.S. Department of Labor.

	(xi) Any violation of, or liability or obligation relating to, Applicable Law, whether now or hereafter in effect (including, without limitation, Environmental Laws, any Permits, any Governmental Approvals, the Consent Decree or any other administrative or judicial orders, agreements or decrees by, with or of any Governmental Entity), arising as a result of, relating to or in connection with any Lessee Person’s Use of the Generating Station, the Facility, the Facility Site, the Ancillary Facilities, or any portion or component thereof or interest therein (including, without limitation, the Undivided Interest); or any action of any Governmental Entity or other person taken with respect to such violation of law or such liability or such obligation, or otherwise in connection with, or relating to, any Lessee Person’s Use of the Generating Station, the Facility, the Facility Site, the Ancillary Facilities, or any portion or component thereof or interest therein (including, without limitation, the Undivided Interest) or the interests of the OP Guarantor, the Owner Participant, the Lessor, the Indenture Trustee, the Pass Through Trustee or the Account Bank under the Operative Documents or the Operating Agreement; or the presence, use, storage, transportation, treatment, disposal, arrangement for or permitting the disposal, handling or manufacture of any Hazardous Substance in, at, under or from the Generating Station, the Facility, the Facility Site, the Ancillary Facilities, or any portion or component thereof or interest therein (including, without limitation, the Undivided Interest) that relates to, or arises out of, any Lessee Person’s current or prior Use of, or prior ownership of, the Generating Station, the Facility, the Facility Site or the Ancillary Facilities;

	(xii) Any act, event or circumstance that imposes strict liability or similar “no-fault” liability on any Lessee Person arising out of, relating to or in connection with the Generating Station, the Facility, the Facility Site, the Ancillary Facilities, or any portion or component thereof or interest therein (including, without limitation, the Undivided Interest) (regardless of whether other persons are also strictly liable or subject to such similar “no fault” liability); or

	(xiii) Subject to clause (g) of this Section 9.1, otherwise as a result of the transactions contemplated by the Operative Documents or a Transaction Party’s participation in the contemplated transactions.

(b) Claims Excluded. Any Claim, to the extent attributable to or arising out of or as a result of any of the following, is excluded from the Lessee’s obligations to indemnify, defend, protect and hold harmless any Indemnified Party under this Section 9.1:

	(i) Claims arising with respect to a period or event occurring after the expiration or earlier termination of the Facility Lease and, if applicable, the return of the use and possession of the Facility Site and the Undivided Interest in accordance with the requirements of the Facility Lease and the Site Lease, other than Claims relating to or arising from events occurring prior to, or simultaneously with, such events;

	(ii) In respect of any of the Indemnified Parties, Claims arising from the gross negligence or willful misconduct of such party or any Affiliate of such party, or any officer, director or employee of the foregoing (in each case except to the extent attributed to the Indemnified Party by reason of its interest in the Undivided Interest or Facility Site or due to a Lessee Person’s Use of the Generating Station, the Facility, the Facility Site, the Ancillary Facilities, or any portion or component thereof or interest therein (including, without limitation, the Undivided Interest);

	(iii) Taxes and costs of contesting Taxes, whether or not separately indemnified for (provided that this clause (iii) shall not affect Lessee’s obligation to pay indemnities pursuant to this Section 9.1 on an After-Tax Basis);

	(iv) Any disposition by the Lessor or the Owner Participant of its interests under the Facility Lease, the Site Lease or the Owner Trust, as the case may be, unless such disposition is required by the terms of the Operative Documents or permitted by Section 10, 13 or 14 of the Facility Lease or occurs during the continuance of a Material Default or a Lease Event of Default;

	(v) In respect of any of the Indemnified Parties, to the extent of the breach of any agreement, covenant, representation or warranty of such party or any Affiliate of such party (in each case except to the extent attributed to the Indemnified Party by reason of its interest in the Undivided Interest or Facility Site or due to a Lessee Person’s Use of the Generating Station, the Facility, the Facility Site, the Ancillary Facilities, or any portion or component thereof or interest therein (including, without limitation, the Undivided Interest));

	(vi) Amendments to the Operative Documents or the Operating Agreement that are not requested or consented to by the Lessee or are not required by the Operative Documents, the Operating Agreement or Applicable Law;

	(vii) Claims arising out of or relating to an inspection of the Undivided Interest by or on behalf of any of the Indemnified Parties seeking indemnification (other than during the continuance of a Lease Event of Default);

	(viii) Any of the Indemnified Parties’ costs of compliance with U.S. regulatory requirements (other than as a result of a Lease Event of Default or those costs arising as a result of a change in Applicable Law that are in whole or

	in part attributable to a Lessee Person’s actual or Alleged Use of the Generating Station, the Facility, the Ancillary Facilities, the Facility Site or any part thereof); and

	(ix) Any of the Indemnified Parties’ overhead costs in monitoring or administering this investment.

	Nothing herein shall be deemed to (A) constitute a guaranty of any useful life or any present or future residual value of the Facility or a guaranty that any amount of any Secured Indebtedness will be paid, or (B) prevent the Lessee from pursuing a Claim against any Lessee Person and any such Claim shall not be subject to indemnification or should otherwise be excluded from indemnification under this Section 9.1.

	(c) Insured Claims. Subject to the provisions of paragraph (d) of this Section 9.1, in the case of any Claim indemnified by the Lessee hereunder which is covered by a policy of insurance maintained by the Lessee, each Indemnified Party agrees, unless it and each other Indemnified Party shall waive its rights to indemnification (for itself and each Related Party thereto) in a manner reasonably acceptable to the Lessee, to cooperate reasonably, at the sole cost and expense of the Lessee, with the Lessee and its insurers in the exercise of their rights to investigate, defend or compromise such Claim.

	(d) Claims Procedure. Each Indemnified Party shall promptly after such Indemnified Party shall have Actual Knowledge thereof notify the Lessee of any Claim as to which indemnification is sought; provided, that the failure so to notify the Lessee shall not reduce or affect the Lessee’s liability which it may have to such Indemnified Party under this Section 9.1; provided further, that upon full payment of the amounts for which indemnification is payable hereunder, the Lessee shall be entitled, to the extent that the Lessee is materially prejudiced in the conduct of or precluded from conducting a meritorious contest of such Claim as a result of such failure, to pursue its legal rights and remedies against such Indemnified Party for actual damages resulting directly from the failure of such Indemnified Party to give the Lessee prompt notice. Subject to the foregoing, any amount payable to any Indemnified Party pursuant to this Section 9.1 shall be paid within 30 days after receipt of such written demand therefor from such Indemnified Party, accompanied by a certificate of such Indemnified Party stating in reasonable detail the basis for the indemnification thereby sought and (if such Indemnified Party is not a party hereto) an agreement to be bound by the terms of this Section 9.1 as if such Indemnified Party were such a party. Promptly after the Lessee 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, the Lessee shall, without affecting its obligations hereunder, notify such Indemnified Party whether it intends to pay, object to, compromise or defend any matter involving the asserted liability of such Indemnified Party. The Lessee shall have the right to investigate and, so long as no Material Default or Lease Event of Default shall have occurred and be continuing, to defend or compromise any Claim for which indemnification is sought under this Section 9.1;

provided that no such defense or any settlement or other compromise shall involve any (i) material risk of foreclosure, sale, forfeiture or loss of, or imposition of a Lien other than a Permitted Lien on, any part of the Facility, the Ancillary Facilities, the Undivided Interest, the Ground Interest, the Facility Site, the Trust Estate or the Indenture Estate or the impairment of the use, operation or maintenance of the Facility, the Ancillary Facilities or the Facility Site, (ii) risk of criminal liability being incurred by such Indemnified Party, the Lessor, the Owner Participant or, if applicable, the OP Guarantor or (so long as the Notes are outstanding and the Lien of the Indenture has not been discharged) the Indenture Trustee or the Pass Through Trustee, or (iii) material risk of any material adverse effect on the interests of the Lessor, the Owner Participant or, if applicable, the OP Guarantor or (so long as the Notes are outstanding and the Lien of the Indenture has not been discharged) the Indenture Trustee or the Pass Through Trustee; provided, further, that no Claim shall be settled or compromised by the Lessee without the express written consent of such Indemnified Party, such consent not to be unreasonably withheld, delayed or conditioned, unless such settlement or compromise does not involve any admission of any criminal violation, gross negligence or willful misconduct on the part of the Indemnified Party, does not involve any relief other than the payment of money damages, and results in an unconditional release of the Indemnified Party with respect to such Claim; 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 Lessee may assume responsibility for the defense or compromise of such Claim only if the same may be and is severed from such other claims. In the event that in the course of the investigation or defense of a Claim, the Lessee shall in good faith reasonably determine that it is not liable for indemnification with respect thereto under this Section 9.1, it may give notice to the applicable Indemnified Party of such fact, and the Lessee may thereupon cease to defend such Claim; provided that (A) the Lessee’s conduct regarding the defense of such Claim or any decision to withdraw from such defense shall not prejudice or have prejudiced the Indemnified Party’s ability to contest such Claim (taking into account, among other things, the timing of the Lessee’s withdrawal and the theory or theories upon which the Lessee shall have based its defense), and (B) the Lessee shall have given such Indemnified Party all materials, documents and records relating to its defense of such Claim as such Indemnified Party shall have reasonably requested in connection with the assumption by such Indemnified Party of the defense of such Claim at the cost and expense of the Lessee. In the event that the Lessee shall cease to defend any Claim pursuant to the preceding sentence, the Lessee shall indemnify each Indemnified Party, without regard to any exclusion that might otherwise apply hereunder, to the extent that the actions of the Lessee in defending such Claim or the manner or time of the Lessee’s election to withdraw from the defense of such Claim shall have caused such Indemnified Party to incur any loss, cost, liability or expense which such Indemnified Party would not have incurred had the Lessee never undertaken to defend such Claim. If the Lessee elects, subject to the foregoing, to defend any such asserted liability, it may do so at its own expense and by counsel selected by it and reasonably satisfactory to such Indemnified Party. The Lessee agrees in any event to keep the Indemnified Party

informed as to all proceedings with respect to any Claim and shall provide such Indemnified Party with copies of all material pleadings and material correspondence and other information relating to any Claim, in each case, as soon as practicable and, with respect to pleadings or other papers required to be filed in court, within a reasonable time to permit review thereof and comment thereon to the extent practicable in the circumstances. Upon the Lessee’s election to defend such asserted liability and prompt notification to such Indemnified Party of its intent to do so, such Indemnified Party shall use commercially reasonable efforts to cooperate at the Lessee’s expense with all reasonable requests of the Lessee in connection therewith and will provide the Lessee with all information not within the control of the Lessee as is reasonably available to such Indemnified Party which the Lessee may reasonably request; provided, however, that such Indemnified Party shall not, unless otherwise required by Applicable Law, be obligated to disclose to the Lessee or any other Person, or permit the Lessee or any other Person to examine, any tax returns of the Indemnified Party or any confidential or privileged information or pricing information not generally accessible by the public possessed by the Indemnified Party unless such Indemnified Party agrees to such disclosure and the Lessee obtains a stipulation from all parties to the related proceeding providing for the confidential treatment of such information. Where the Lessee, or the insurers under a policy of insurance maintained by the Lessee, undertakes the defense of such Indemnified Party with respect to a Claim (with counsel reasonably satisfactory to such Indemnified Party), no additional legal fees or expenses of such Indemnified Party in connection with the defense of such Claim shall be indemnified hereunder unless such fees or expenses were incurred at the request of the Lessee or such insurers. Notwithstanding the foregoing, an Indemnified Party may participate at its own expense in any judicial proceeding controlled by the Lessee, pursuant to the preceding provisions, but only to the extent that such party’s participation does not in the reasonable opinion of counsel to the Lessee interfere with such control or defense of such claim; provided, however, that such party’s participation does not constitute a waiver of the indemnification provided in this Section 9.1; and provided, further, that if and to the extent that (1) such Indemnified Party is advised by counsel that an actual or potential conflict of interest exists where it is advisable for such Indemnified Party to be represented by separate counsel or (2) there is a risk that such Indemnified Party may be subject to criminal liability and such Indemnified Party informs the Lessee that such Indemnified Party desires to be represented by separate counsel or (3) the Lessee has not defended the Claim diligently and in good faith, such Indemnified Party 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 the Lessee. So long as no Material Default or Lease Event of Default described in clause (a), (b), (g) or (h) of Section 16 of the Facility Lease has occurred and be continuing, no Indemnified Party shall enter into any settlement or other compromise with respect to any Claim without the prior written consent of the Lessee, such consent not to be unreasonably withheld, delayed or conditioned, unless (I) the Indemnified Party waives its rights to indemnification hereunder or (II) the Lessee has not acknowledged its indemnity obligation with respect thereto or (III) the

	Indemnified Party has the right to control its own defense of such Claim pursuant to clause (2) or (3) of the immediately preceding sentence. Nothing contained in this Section 9.1(d) shall be deemed to require an Indemnified Party to contest any Claim or to assume responsibility for or control of any judicial proceeding with respect thereto.

	(e) Subrogation. To the extent that a Claim indemnified by the Lessee under this Section 9.1 is in fact paid by the Lessee or an insurer under an insurance policy maintained by the Lessee (so long as no Material Default or Lease Event of Default shall have occurred and be continuing), such insurer shall be subrogated to the rights and remedies of the Indemnified Party on whose behalf such Claim was paid to the extent of such payment (other than rights of such Indemnified Party under insurance policies maintained at its own expense) with respect to the transaction or event giving rise to such Claim. Should an Indemnified Party receive any refund, in whole or in part, with respect to any Claim paid by the Lessee hereunder, it shall promptly pay over to the Lessee 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 not in excess of the amount of such reduction) saved as a result of such payment or (ii) the amount the Lessee or any of its insurers has paid in respect of such Claim; provided, however, that if a Material Default or a Lease Event of Default shall have occurred and be continuing, the Lessor may apply any such amounts to amounts which have become due and payable by the Lessee attributable thereto.

	(f) Minimize Claims. The Owner Participant, the Lessor, and each of the other Transaction Parties will use their respective reasonable efforts to minimize Claims indemnifiable by the Lessee under this Section 9.1, including by complying with reasonable requests by the Lessee to do or to refrain from doing any act if such compliance is, in the good faith opinion of the Owner Participant, the Lessor, or such other Transaction Party, as the case may be, of a purely ministerial nature or otherwise has no unindemnified adverse impact on the Owner Participant, the Lessor, or such Transaction Party, as the case may be, or any Affiliate of any thereof or on the business or operations of any of the foregoing.

Section 9.2. General Tax Indemnity.

(a) Indemnity. Except as provided in paragraph (b) below, the Lessee agrees to indemnify each of the Owner Participant, the Lessor, the Trust Company (in its individual capacity and as Owner Trustee), the Indenture Trustee, and the Pass Through Trustee and their respective Affiliates (each of the foregoing, a “Tax Indemnitee”) for, to hold each Tax Indemnitee harmless from and to defend each Tax Indemnitee against all Taxes that are imposed upon or with respect to or borne by or asserted against any Tax Indemnitee, the Facility, the Undivided Interest, the Facility Site, the Ground Interest, or any portion or Component thereof or any interest therein, or upon any Operative Document or interest therein, or in any way arising out of, in connection with or relating to, any of the following:

	(i) the acceptance, rejection, delivery, construction, financing, refinancing, acquisition, operation, ownership, possession, maintenance, repair, lease, condition, alteration, modification, restoration, refurbishing, rebuilding, return, transport, assembly, repossession, servicing, dismantling, abandonment, retirement, decommissioning, preparation, installation, storage, replacement, purchase, sale or other disposition, insuring, sublease, or other use or non-use of, the imposition of any lien (or incurrence of any liability to refund or pay over any amount as a result of any lien) on, the Facility, the Undivided Interest, the Ground Interest, the Facility Site or any portion or Component thereof or any interest therein;

	(ii) the conduct of the business or affairs of the Lessee, the Guarantor or FirstEnergy, the Facility or the Facility Site;

	(iii) the execution or delivery of the Operative Documents or any other documents contemplated thereby or the performance, enforcement or amendment of any terms thereof;

	(iv) the payment or receipt of Periodic Rent and Supplemental Rent or any other payment, receipt or earning under the Operative Documents;

	(v) the conveyance of title to the Undivided Interest; or

	(vi) otherwise relating to the transactions contemplated by the Operative Documents.

	(b) Excluded Taxes. There shall be no indemnification under paragraph (a) above for any of the following Taxes (the “Excluded Taxes”):

	(i) United States federal income Taxes imposed under Subtitle A of the Code (including minimum taxes).

	(ii) Taxes, including franchise Taxes, which are based on or measured by the net or gross income, capital or net worth, net or gross receipts, excess profits, capital gain or conduct of business (including minimum taxes) (other than Taxes that are, or are in the nature of, sales, use, value-added, property, ad valorem, rental, stamp, transfer, excise or license Taxes) (“Income Taxes”) imposed by (i) the Commonwealth of Pennsylvania (or any local jurisdiction or taxing authority located therein), (ii) any foreign government or any foreign taxing authority, (iii) a taxing authority in any jurisdiction in which the Tax Indemnitee is organized, incorporated or has its principal place of business or is otherwise subject to Income Taxes as a result of income, assets or activities that are unrelated to the Transactions, and (iv) any other government or taxing authority, in each case other than Income Taxes imposed as a result of (A) the location, or the use or operation by a Lessee Person, of the Undivided Interest, the

	Facility Site, the Ancillary Facilities or the Facility, or the recording or registration of any Tax Indemnitee’s interest in any of the foregoing, in the jurisdiction imposing such Tax, (B) the execution or delivery of any Operative Document in such jurisdiction, (C) the identity, organization, incorporation, activities or presence of a Lessee Person or (D) the making of any payment under the Operative Documents by or on behalf of the Lessee or any related person (collectively, a “Lessee Nexus”).

	(iii) Taxes imposed with respect to a period or event occurring after the expiration or earlier termination of the Facility Lease and, if applicable, the return of the use and possession of the Facility Site and the Undivided Interest in accordance with the requirements of the Facility Lease and the Site Sublease, other than Taxes (i) relating to or arising from events occurring prior to, or simultaneously with, such events or (ii) imposed with respect to any payments due under the Operative Documents.

	(iv) Taxes based on or measured by the fees or other compensation of the Owner Trustee, the Indenture Trustee, the Pass Through Trustee and the Account Bank in connection with the Transactions.

	(v) Taxes imposed on a Tax Indemnitee (i) resulting from the gross negligence, fraud or willful misconduct of such Tax Indemnitee or a related person or (ii) that would not have occurred but for the breach or inaccuracy by such Tax Indemnitee of any of its representations, warranties, covenants or obligations under the Operative Documents.

	(vi) Taxes that are being contested in accordance with Section 9.2(g) during the pendency of such contest.

	(vii) Taxes resulting from (i) a voluntary sale, assignment, transfer or other disposition (A) by such Tax Indemnitee of any interest in the Undivided Interest or any part thereof or (B) of any interest in the Tax Indemnitee, provided, in each case, such sale, assignment, transfer or other disposition is not while a Lease Event of Default is continuing or (ii) any involuntary sale, assignment, transfer or other disposition of the foregoing interests resulting from any bankruptcy or other proceeding for the relief of debtors in which such Tax Indemnitee is a debtor, or from any foreclosure by a creditor of such Tax Indemnitee in each case not attributable to a Lease Default or Lease Event of Default.

	(viii) Taxes incurred or payable by a transferee (including any transfer by merger, consolidation, liquidation, reorganization or otherwise by operation of law) of a Tax Indemnitee to the extent of the excess of such Taxes over the amount of such Taxes which would have been imposed on the original Tax Indemnitee had there been no transfer (determined pursuant to Applicable Law in

	effect at the time of the transfer); provided that such transfer is not while a Lease Event of Default is continuing.

	(ix) Taxes in the nature of an intangible or similar Tax, unless arising as a result of a Lessee Nexus.

	(x) Taxes imposed on any Tax Indemnitee that would not have been imposed but for the Lessor being organized outside the United States or treated as other than a U.S. Person (as defined in Section 7701(a)(30) of the Code) or a grantor trust or a pass through entity for U.S. federal income tax purposes.

	(xi) Taxes that have been included in the Purchase Price.

	(xii) Taxes that result from the failure of a Tax Indemnitee to comply, following notice from the Lessee, with certification, reporting, filing or other similar requirements of the jurisdiction imposing such Tax.

	(xiv) Value added taxes imposed on a Tax Indemnitee, unless arising as a result of a Lessee Nexus.

(c) Payment. All payments by the Lessee pursuant to this Section 9.2 shall be made on an After-Tax Basis. Each payment required to be made by the Lessee to a Tax Indemnitee pursuant to this Section 9.2 shall be paid either (i) when due directly to the applicable taxing authority by the Lessee 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) 30 days following the Lessee’s receipt of the Tax Indemnitee’s written demand for the payment pursuant to clause (g)(i) below (which demand shall be accompanied by a written statement of the Tax Indemnitee describing in reasonable detail the Taxes for which the Tax Indemnitee is demanding payment and the computation of such Taxes), (B) subject to paragraph (g) below, in the case of amounts which are being contested pursuant to such paragraph (g), at the time and in accordance with a final determination of such contest, (C) in the case of any indemnity demand for which the Lessee has requested review and determination pursuant to paragraph (d) below, the completion of such review and determination; provided, however, except with respect to amounts being contested pursuant to paragraph (g) below, in no event later than the date which is one Business Day prior to the date on which such Taxes are required to be paid to the applicable taxing authority, or (D) any other such time or times as requested by the Lessee acting in good faith and agreed to by the Tax Indemnitee. Any amount payable to the Lessee pursuant to paragraph (e) or (f) below shall be paid promptly 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 the Lessee has made a Tax Advance, the amount of the Lessee’s obligation under paragraph (a) above shall be reduced by such Tax Advance. Any obligation of the Lessee under this Section 9.2 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 days of such final determination.

	(d) Independent Examination. Within ten days after the Lessee receives any computation from the Tax Indemnitee, the Lessee may request in writing that an independent public accounting firm selected by the Tax Indemnitee and reasonably acceptable to the Lessee review and determine on a confidential basis the amount of any indemnity payment by the Lessee to the Tax Indemnitee pursuant to this Section 9.2 or any payment by a Tax Indemnitee to the Lessee pursuant to paragraph (e) or (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 such accounting firm shall agree in writing in a manner reasonably satisfactory to the Tax Indemnitee to maintain the confidentiality of such information. 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 9.2 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. The fees and disbursements of such accounting firm will be paid by the Lessee; provided that such fees and disbursements will be paid by the Tax Indemnitee if the verification results in an adjustment in the Lessee’s favor of five percent or more of the indemnity payment or payments as originally computed by the Tax Indemnitee.

	(e) Tax Benefit. If, as the result of any Taxes paid or indemnified against by the Lessee under this Section 9.2, the aggregate Taxes actually paid by the Tax Indemnitee for any taxable year and not subject to indemnification pursuant to this Section 9.2 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 the Lessee under paragraph (a) or (c) above and provided no Material Default or Lease Event of Default shall have occurred and be continuing (in which event the payment provided under this Section 9.2(e) shall be deferred until the Material Default or Lease Event of Default has been cured), such Tax Indemnitee shall pay to the Lessee the lesser of (i) (A) the amount of such Tax Benefit, plus (B) an amount equal to any additional Tax Savings realized by the Tax Indemnitee as a result of the payment under clause (A) above and this clause (B) and (ii) the amount of the indemnity paid pursuant to this Section 9.2 giving rise to such Tax Benefit; provided, however, that any excess of (i) over (ii) shall be carried forward and reduce the Lessee’s obligations to make subsequent payments to such Tax Indemnitee pursuant to this Section 9.2. 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 Lessee must indemnify the Tax Indemnitee pursuant to this Section 9.2 without regard to paragraph (b) hereof (other than clauses (v) and (xii) of paragraph (b)).

	Notwithstanding anything to the contrary herein, each Tax Indemnitee and the Lessee shall determine the allocation of any Tax benefits, savings, credit, deduction or allocation in its sole good faith discretion and each position to be taken on its Tax return shall be in its sole control and it shall not be required to disclose any Tax return or related documentation to any Person.

	(f) Refund. If a Tax Indemnitee obtains a refund or credit of all or part of any Taxes paid, reimbursed or advanced by the Lessee pursuant to this Section 9.2, the Tax Indemnitee promptly shall pay to the Lessee (i) 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 (ii) any additional Tax Savings realized by such Tax Indemnitee by reason of such payment to the Lessee; provided that (A) if at the time such payment is due to the Lessee a Material Default or Lease Event of Default shall have occurred and be continuing, such amount shall not be payable until such Material Default or Lease Event of Default has been cured, and (B) the amount payable to the Lessee 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 the Lessee. Any excess of (i) and (ii) over (B) in this Section 9.2(f) shall be carried forward and reduce the Lessee’s obligations to make subsequent payments to such Tax Indemnitee pursuant to this Section 9.2. 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 the Lessee must indemnify the Tax Indemnitee pursuant to this Section 9.2 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 the Lessee pursuant to this Section 9.2, a Tax Indemnitee receives an amount representing interest on such refund or credit, the Tax Indemnitee promptly shall pay to the Lessee (1) the amount of such interest that shall be fairly attributable to such Taxes paid, reimbursed or advanced by the Lessee 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 (1) and (2).

	(g) Contest.

(i) Notice of Contest. If a written claim for payment is made by any taxing authority against a Tax Indemnitee for any Taxes with respect to which the Lessee may be liable for indemnity hereunder (a “Tax Claim”), such Tax Indemnitee shall give the Lessee written notice of such Tax Claim promptly after its receipt, and shall furnish the Lessee with copies of such Tax Claim and all other writings received from the taxing authority to the extent relating to such Tax Claim; provided that, without limiting any damage claims or remedy the Lessee

	may otherwise have for such failure, failure to so notify the Lessee shall not relieve the Lessee of any obligation to indemnify the Tax Indemnitee hereunder except to the extent that such failure increases the amount otherwise required to be paid pursuant to this Section 9.2.

	(ii) Control of Contest. Subject to paragraph (g)(iii) below, at the election of the Lessee, the Lessee (A) will be entitled to contest (acting through counsel selected by the Lessee and reasonably satisfactory to the Tax Indemnitee), and control the contest of, any Tax Claim either in its own name or the name of the Tax Indemnitee if (x) such Tax Claim may be pursued independently from any claim for Taxes for which the Lessee is not obligated to indemnify the Tax Indemnitee, (y) the Lessee shall have acknowledged in writing its liability hereunder if the Tax Claim is not successful, and (z) the Tax Indemnitee has reasonably determined, acting in good faith, that it will not be adversely affected by the Lessee’s control of such Tax Claim (a “Lessee-Controlled Contest”), or (B) may require that the Tax Indemnitee in good faith contest such Tax Claim. The following rules shall apply with respect to any contest hereunder:

	(1) With respect to a Lessee-Controlled Contest:

	a. the Lessee shall control any such claim (acting through counsel selected by the Lessee and reasonably satisfactory to the Tax Indemnitee) at the Lessee’s expense;

	b. the decisions regarding what actions to be taken shall be made by the Lessee in its sole judgment, acting reasonably and in good faith; and

	c. the Tax Indemnitee shall not otherwise settle, compromise or abandon such contest without the Lessee’s prior written consent except as provided in paragraph (g)(iv) below; and

	d. the Lessee shall consult in good faith with the Tax Indemnitee and its designated counsel with respect to such Tax Claim and shall provide the Tax Indemnitee with copies of any reports or claims (or extracts therefrom) issued by the relevant auditing agents or taxing authority relating to such Tax Claim.

	(2) With respect to the contest of any Tax Claim pursuant to clause (B) of Section 9.2(g)(ii) hereof:

a. the Tax Indemnitee shall control any such claim (acting through counsel selected by the Tax Indemnitee and reasonably satisfactory to the Lessee) at the Lessee’s expense;

	b. the decisions regarding what actions to be taken shall be made by the Tax Indemnitee in its sole judgment, acting reasonably and in good faith;

	c. the Tax Indemnitee shall not otherwise settle, compromise or abandon such contest without the Lessee’s prior written consent, except as provided in paragraph (g)(iv) below; and

	d. the Tax Indemnitee shall consult in good faith with the Lessee and its designated counsel with respect to such Tax Claim and shall provide the Lessee with copies of any reports or claims (or extracts therefrom) issued by the relevant auditing agents or taxing authority relating to such Tax Claim.

	(iii) Conditions of Contest. Notwithstanding the foregoing, no contest with respect to a Tax Claim will be required or permitted pursuant to this Section 9.2, and the Lessee shall be required to pay the applicable Taxes without contest, unless:

	(1) within 30 days after written notice by the Tax Indemnitee to the Lessee of such Tax Claim (or such shorter period, to be specified by the Tax Indemnitee in such notice, as required for taking action with respect to such Tax Claim), the Lessee shall request in writing to the Tax Indemnitee that such Tax Claim be contested,

	(2) no Material Default or Lease Event of Default has occurred and is continuing,

	(3) there is no reasonably foreseeable risk of sale, forfeiture or loss of, or the creation of any Lien on, 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,

	(4) there is no reasonably foreseeable risk of imposition of any criminal penalties or liabilities,

	(5) if such contest involves payment of such Tax, the Lessee has advanced such amount necessary to pay the Tax to the Tax Indemnitee or its Affiliates on an interest-free basis and with no after-Tax cost to such Tax Indemnitee (a “Tax Advance”),

	(6) the Lessee has agreed to pay (and pays on demand), and with no after-Tax cost to such Tax Indemnitee or its Affiliates, 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 and penalties, interest and additions to Tax),

	(7) if the subject matter of such claim shall be of a continuing or recurring nature and shall have previously been decided pursuant to this paragraph (g), there shall have been a change in law after such previously decided claim and such Tax Indemnitee receives, at the Lessee’s sole cost, an opinion of counsel selected by such Tax Indemnitee and reasonably acceptable to the Lessee to the effect that such change is favorable to the position asserted in the previous contest,

	(8) no appeal to the U.S. Supreme Court shall be required or permitted, and

	(9) in the case of a Tax Claim other than a Lessee-Controlled Contest, the amount of the claim and all future related claims exceeds $25,000 and, if requested by the Tax Indemnitee, the Lessee shall have delivered to the Tax Indemnitee an opinion of Independent Tax Counsel that there is a reasonable basis to contest such Tax Claim.

	(iv) Waiver of Indemnification. Notwithstanding anything to the contrary contained in this Section 9.2, the Tax Indemnitee at any time may elect to decline to take any action or any further action with respect to (and the Lessee shall not be permitted to contest) a Tax Claim and may in its sole discretion settle or compromise any contest with respect to such Tax Claim without the Lessee’s consent if the Tax Indemnitee:

	(1) waives its right to any indemnity payment by the Lessee pursuant to this Section 9.2 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

	(2) promptly repays to the Lessee any Tax Advance and any amount paid to such Tax Indemnitee under Section 9.2(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 9.2, the Lessee will (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 (1) unless directed by the Tax Indemnitee otherwise, if permitted by Applicable Law, prepare such report, statement or return for filing by the Lessee in such manner as will show the ownership of the Undivided Interest by the 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 (2) in all other cases, 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 that the only consequence for failure of the Tax Indemnitee to file such report, statement or return after compliance by the Lessee with the requirements hereof shall be a loss of indemnification from the Lessee in respect of any Tax to the extent resulting from such failure.

	(ii) Each of the Tax Indemnitee and the Lessee, as the case may be, will timely provide the other, at the Lessee’s expense, with all information in its possession that the other party may reasonably require and request to satisfy its Tax filing obligations; provided that the Owner Participant and its Affiliates shall not be required to provide to the Lessee, and the Lessee shall not be required to provide to any Tax Indemnitee, copies of its income tax returns or any other information in respect of its income tax returns or reporting positions that such Person considers confidential.

(i) Non-Parties. If a Tax Indemnitee is not a party to this Agreement, the Lessee may require such Tax Indemnitee to agree in writing, in a form reasonably acceptable to the Lessee, to the terms of this Section 9.2 and any other relevant provision hereof prior to making any payment to such Tax Indemnitee under this Section. Subject to the preceding sentence, the Lessee’s obligations under this Section 9.2 shall inure to the benefit of each and every Tax Indemnitee without regard to whether such Tax Indemnitee is a party to this Agreement.

SECTION 10. LESSEE’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, the Site Lease and the 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 and neither the Lessor nor the Indenture Trustee (as assignee of the Lessor) has commenced the exercise of remedies under the Facility Lease that it may have therein as a result thereof, it shall not take or cause to be taken any action or direct that any action be taken that would interfere with or interrupt the quiet enjoyment of the use, operation and possession by the Lessee of its rights and interests in the Undivided Interest or the Ground Interest subject to the terms of the Facility Lease and the Site Sublease.

SECTION 11. SUPPLEMENTAL FINANCING MODIFICATIONS; OPTIONAL REFINANCINGS

Section 11.1. Financing Modifications. Upon the request of the Lessee delivered at least 30 days prior to any proposed financing of a portion of the cost of any Required Modification or non-Severable Modification and subject to the consent of the Owner Participant, the Lessor and the Indenture Trustee shall cooperate with the Lessee, to the extent permitted under Rev. Proc. 2001-28, to (a) issue Additional Notes under the Indenture to finance such Modification which will rank pari passu with the Initial Notes and/or any Additional Notes then outstanding; (b) execute and deliver one or more supplements to the Indenture for the purpose of subjecting the Lessor’s interest in any such Modifications to the Liens thereof, and (c) execute and deliver an amendment to the Facility Lease to reflect the adjustments required by clause (c) below. If the Owner Participant consents to finance such Modifications through the issuance of Additional Notes under Section 2.12(a) of the Indenture (any financing of Modifications through the issuance of such Additional Notes under the Indenture being called a “Supplemental Financing”), such Supplemental Financing shall be subject to the following additional conditions:

	(a) The Basic Rent and Termination Amounts (determined without regard to any Tax benefits associated with such Modifications, unless the Owner Participant is making an Additional Equity Investment) shall, subject to Section 12.2, be adjusted as agreed to by the Owner Participant and Lessee at the time of such financing;

	(b) The Rating Agencies have confirmed that such financing shall not result in a withdrawal or downgrade of the credit rating of the Pass Through Certificates below that in effect on the date of the financing (except that, in respect of Required Modifications, this clause (B) will not be applicable);

	(c) Such financing is for an amount not greater than the Lessor’s Percentage of the cost of the Modifications being financed, nor for an amount less than $20 million multiplied by the Lessor’s Percentage;

	(d) As of the closing date of the Supplemental Financing, the aggregate balance of the Notes (including the additional debt being financed and taking into account all Modifications) shall not exceed 87% of the fair market value of the Undivided Interest;

	(e) No Lease Event of Default shall have occurred and be then continuing unless the Modifications are intended to cure such Lease Event of Default and comply in all material respects with the Operative Documents;

	(f) The final maturity date of the Additional Notes will be no later than the final maturity date of the Initial Notes and will be repaid in full out of additional Basic Rent during the Lease Term;

	(g) The Owner Participant shall have received an opinion of independent tax counsel to the effect that such Supplemental Financing will not cause any adverse Tax consequences to the Owner Participant;

	(h) The Supplemental Financing shall not change the Owner Participant’s treatment of the transaction under FASB 13;

	(i) The Supplemental Financing shall not result in any “prohibited transaction” within the meaning of Section 406 of ERISA or Section 4975 of the Code; and

	(j) The Owner Participant shall be paid a fee of $100,000 in connection with such Supplemental Financing.

Section 11.2. Cooperation. The Owner Participant will consider in good faith any requests by the Lessee to refinance the Lease Debt; provided that any such refinancing of the Lease Debt shall otherwise be in accordance with the terms of the Operative Documents and other conditions to such refinancing agreed to by Lessee and the Owner Participant shall have been satisfied.

Section 11.3. Other Financing. Notwithstanding the foregoing in this Section 11, the Lessee shall, at any and all times, have the right to fund Modifications to the Facility other than through the Facility Lease.

SECTION 12. CERTAIN ADJUSTMENTS TO PERIODIC RENT, TERMINATION AMOUNTS AND OTHER
AMOUNTS

Section 12.1. Pre-Closing Adjustments. Prior to the Closing Date, the Rent Factors shall be adjusted, either upward or downward, as the case may be (in either case, a “Rent Adjustment”), in the event of either of the following:

	(a) to reflect any changes in the Pricing Assumptions (including any changes in the assumed amortization schedules for the Notes) or the Tax Assumptions from those specified in Schedule 2 hereto and in Section 1 of the Tax Indemnity Agreement, respectively; and

	(b) at the request of the Lessee or the Owner Participant, to reflect any enactment, promulgation, release or adoption of, amendment to or change in the Code or Treasury Regulations (other than changes affecting alternative minimum tax provisions) (“Tax Law Change”) that is enacted, promulgated, released or adopted prior to the Closing Date and effective in respect of the U.S. federal income tax treatment of the Overall Transaction.

Rent Adjustments will be calculated by the Owner Participant so as to preserve the Owner Participant’s Net Economic Return without altering the credit profile such that the Termination Amount reflected on the relevant schedule attached to the Form of Facility Lease Agreement attached as Exhibit C on any Termination Date while the Notes are outstanding shall

not increase by more than 1.0% of the Purchase Price; provided, however, that each adjustment of Basic Rent and Allocated Rent shall comply with the requirements of Rev. Proc. 2001-28, as modified and as in effect at the time of such adjustment, and Section 467 of the Code and any proposed, temporary or final regulations thereunder as in effect at the time of such adjustment, and shall not cause the Facility Lease to be a “disqualified leaseback or long-term agreement” within the meaning of Section 467 of the Code and any such regulations thereunder. Such adjustment and the corresponding adjustments to the other Rent Factors shall be computed by such Owner Participant on the same basis that was used in calculating the Rent Factors as set forth in the schedules to the Facility Lease on the date hereof.

If any adjustment required by this Section 12.1 would result in (A) the Facility Lease not qualifying as an operating lease for the Lessee under FASB 13 or FASB 98, or (B) the aggregate of all rent adjustments made on or before, or contemplated to be made on, the Closing Date (other than adjustments to reflect a change in Transaction Expenses or the actual interest rate of the Pass Through Certificates) causing the after-tax net present value of Basic Rent discounted at the Discount Rate to increase by more than 100 basis points from the amounts reflected on Schedule 1-A to the form of the Facility Lease attached as Exhibit C, then the Lessee shall not be obligated to close the Overall Transaction. Any adjustment pursuant to this Section 12.1 shall be calculated, at the option of the Lessee, to minimize the average annual Basic Rent over the Basic Term for the Lessee’s GAAP accounting purposes and/or the net present value to the Lessee of the Basic Rent.

Section 12.2. Post-Closing Adjustments.

Any adjustments after the Closing Date in the Basic Rent and the Termination Amounts shall be made only as the Lessee and the Lessor may agree in accordance with the terms of the Facility Lease.

SECTION 13. TRANSFER OF THE LESSEE OWNERSHIP

Section 13.1. No Assignment of Operative Documents. The Lessee covenants and agrees that it shall not during the Lease Term assign the Facility Lease or any other Operative Document, or any interest therein, without the prior written consent of the Owner Participant, such consent not to be unreasonably withheld, delayed or conditioned, but subject to Section 13.2 hereof. Notwithstanding the foregoing, but subject to Section 13.2 hereof, the Lessee may assign all or any part of the Facility Lease, its leasehold interest therein, and any other Operative Document to which it is a party, or any interest therein, to any of its Affiliates without the consent of the Lessor, the Owner Participant, the Indenture Trustee or any other Transaction Party.

Section 13.2. Conditional Assignment. Assignment under Section 13.1 hereof by the Lessee shall be permitted (i) if the Lessee continues to remain liable under the Facility Lease and the other Lessee Documents after giving effect to such assignment or assignments and the Guarantor shall remain fully liable for its obligations under the Guaranty, and (ii) the following conditions have been satisfied:

	(a) The Lessor, Owner Participant, Indenture Trustee and Pass Through Trustee shall have received opinions of counsel (in form and substance reasonably satisfactory to such recipients) (A) to the effect that all regulatory approvals required in connection with such assignment or necessary to assume the Lessee’s obligations under the Lessee Documents shall have been obtained; and (B) as to the assignment and assumption agreement referred to below.

	(b) Such assignment shall be pursuant to an assignment and assumption agreement in form and substance reasonably satisfactory to the Lessor, Owner Participant, Indenture Trustee and Pass Through Trustee.

	(c) No Material Default or Lease Event of Default shall have occurred and be then continuing or would result from such assignment that has not been waived.

	(d) The assignment shall not cause the regulation of the Owner Participant or the Lessor as a public utility or public utility holding company.

	(e) The assignment shall not result in a Regulatory Event of Loss.

	(f) The Lessee shall pay, on an After-Tax Basis, all reasonable, documented, out-of-pocket expenses (including reasonable and documented fees and expenses of its outside counsel) of the Lessor, the Owner Participant, the Indenture Trustee and the Pass Through Trustee in connection with such assignment.

SECTION 14. MISCELLANEOUS

Section 14.1. Consents; Cooperation. The Owner Participant covenants and agrees that it shall not unreasonably withhold or delay its consent with respect to any consent requested of the Lessor under the terms of the Operative Documents that by its terms is not to be unreasonably withheld or delayed by the Lessor.

Section 14.2. Successor Owner Trustee. The parties hereto agree that the transfer or assignment pursuant to the terms of the Trust Agreement by the Owner Trustee to a successor Owner Trustee will not violate the terms of any Operative Document.

Section 14.3. 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 the Bankruptcy 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 Notes, and (c) the Indenture Trustee actually receives any Excess Amount, as defined below, which reflects any payment by the Owner Participant on account of clause (b) above, the Indenture Trustee shall promptly refund to the Owner Participant such Excess Amount (and, to the extent so refunded, such amount owing under the Notes shall be reinstated). For purposes of this Section 14.3, “Excess Amount” means the amount by which

such payment exceeds the amount which would have been received by the Indenture Trustee if the Owner Participant had not become subject to the recourse liability referred to in clause (b) above.

Section 14.4. Notices. Unless otherwise expressly specified or permitted by the terms hereof, all communications and notices provided for herein shall be in writing or by telecopy transmission, 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 telecopy transmission, upon receipt by the sender of a confirmation report that all pages of the telecopy transmission were properly transmitted, 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:
