responsibility for the defense of such Claim at the expense of the Lessee, provided that there shall only be one common counsel for all Loan Participants and the Indenture Trustee and one common counsel for the Lessor and the Owner Participant, unless in each case any such Person reasonably determines that an actual or potential conflict of interest exists; provided further that the Lessee shall acknowledge in writing its obligation to indemnify such Indemnitee as a condition to assuming control of such contest, provided that such acknowledgment of obligation to indemnify will not be binding if the contest is resolved in a manner which indicates that the Lessee would not be liable in the absence of such acknowledgment. The Lessee will provide the Indemnitee with such information not within the control of such Indemnitee, as is in the Lessee’s control or is reasonably available to the Lessee, which such Indemnitee may reasonably request and shall otherwise cooperate with such Indemnitee so as to enable such Indemnitee to investigate or defend any Claim. The Lessee, at its expense, shall keep the Indemnitee which is the subject of such proceeding fully apprised of the status of such proceeding and shall provide such Indemnitee with all information with respect to such proceeding as such Indemnitee shall reasonably request. In the event an Indemnitee has assumed control of any such proceeding, it, at the Lessee’s expense, shall keep the Lessee fully apprised of the status of such proceeding and shall provide the Lessee with all information, including the receipt of all settlement offers, with respect to such proceeding as the Lessee shall reasonably request. If the Lessee or the insurers under a policy of insurance maintained by the Lessee undertake the defense of an Indemnitee with respect to a Claim, no additional legal fees or expenses of such Indemnitee in connection with the defense of such claim shall be indemnified hereunder unless such fees or expenses were incurred at the request of the Lessee or such insurers; provided that, if (i) in the opinion of counsel to such Indemnitee an actual or potential conflict of interest exists where it is advisable for such Indemnitee to be represented by separate counsel or (ii) such Indemnitee has been indicted or otherwise charged in a criminal complaint, or, in the opinion of such Indemnitee such indictment or charge is possible, in connection with a Claim not excluded by Section 12.1(a) and such Indemnitee informs the Lessee that such Indemnitee desires to be represented by separate counsel, the reasonable fees and expenses of such separate counsel shall be borne by the Lessee. Subject to the requirements of any policy of insurance, an Indemnitee may participate at its own expense in any judicial proceeding controlled by the Lessee pursuant to the preceding provisions and such participation shall not constitute a waiver of the right to receive the indemnification provided in this Section 12.1. Notwithstanding anything to the contrary contained herein, except as otherwise provided in the following sentence, during the continuance of a Significant Lease Default or Lease Event of Default, the Lessee shall not compromise any Claim without the consent of the applicable Indemnitee, such consent not to be unreasonably withheld, unless such Claim does not involve the possibility of criminal liability and is simultaneously discharged. Notwithstanding anything to the contrary contained in this Section 12.1, to the extent the defense or settlement of any non-criminal Claim in respect of which an Indemnitee is entitled to indemnification hereunder is governed by the terms of the Joint Operating Agreement, such defense or settlement shall be governed by the Joint Operating Agreement; provided, that the defense or settlement of such Claim in accordance with the Joint Operating Agreement shall not limit the Lessee’s obligations to indemnify such Claim pursuant to this Section 12.1.

(d) Subrogation. Upon payment in full of any Claim by the Lessee pursuant to this Section 12.1 to or on behalf of an Indemnitee, the Lessee, without any further action, shall be subrogated to any and all claims that such Indemnitee may have in respect of the matters against which such indemnity was given (other than Claims under any insurance policies maintained by

Participation Agreement

such Indemnitee); provided that the Guarantor will not exercise any rights which it may acquire by way of rights of subrogation under this Section 12.1(d) until all of the obligations of the Lessee under the Operative Documents to which it is a party have been indefeasibly paid in full. Such Indemnitee agrees to cooperate, at the Lessee’s expense, with the Lessee and to execute such further instruments reasonably requested by the Lessee to permit the Lessee to pursue such Claims.

(e) Refunds. Upon receipt by any Indemnitee of a repayment or reimbursement of all or any part of any Claim for which the Lessee shall have paid to any Indemnitee or for which the Lessee shall have reimbursed any Indemnitee pursuant to this Section 12.1, such Indemnitee shall pay to the Lessee, as promptly as practicable after the receipt thereof, the amount of such repayment or reimbursement plus the amount of any tax savings realized by such Indemnitee as a result of such payment made to the Lessee, but not in excess of the amount of all prior payments made by the Lessee pursuant to this Section 12.1 with respect to such Claim less the amount of all prior refunds paid by such Indemnitee with respect to such Claim pursuant to this subsection (e).

(f) Waiver. The Lessee hereby waives and releases any claim (except any claim relating solely to the Indemnitee’s gross negligence or willful misconduct) now or hereafter existing against any Indemnitee arising out of death or personal injury to personnel of the Lessee (including it directors, officers, employees, agents and servants), loss of damage to property of the Lessee or its Affiliates, or the loss of use of any property of the Lessee or its Affiliates, which may result from or arise out of the condition, use or operation of the Platform during the Lease Term, including any latent or patent defect whether or not discoverable.

12.2 General Tax Indemnification. (a)(1) Payment of Taxes. The Lessee agrees that each payment of Rent pursuant to the Lease shall be free of all withholding with respect to Taxes (other than Excluded Taxes), and in the event that the Lessee shall be required by applicable law to make any such withholding for any such payment, (x) Rent payable shall be increased so that after making all required withholdings the Tax Indemnitee receives an amount equal to the Rent it would have received had such withholdings not been made, (y) the Lessee shall make any such withholdings and (z) the Lessee shall pay the full amount withheld to the relevant taxing authority in accordance with applicable law. Each Tax Indemnitee also agrees (subject to the proviso in Section 12.2(f)) to reimburse the Lessee for any amounts withheld for which such Tax Indemnitee obtains a credit or refund, within 30 days after receipt of such credit or refund.

(2) Indemnity. Except as provided in Section 12.2(b), the Lessee agrees to pay, and to indemnify, protect, defend, save and keep harmless each Tax Indemnitee, on an After-Tax Basis, whether or not any or all of the transactions contemplated hereby are consummated in whole or in part, from and against any and all taxes, impositions, fees, levies, assessments, duties, withholdings, governmental claims or other charges of any nature whatsoever (together with any related interest, fines, penalties or additions to tax), including, without limitation, rental, income, withholding, sales, use, transfer, leasing, personal property, excise, receipts, franchise, value-added, stamp, filing, recording, documentation or license taxes, however imposed or asserted, by any United States federal, state or local government or taxing authority (including any possession or territory thereof) or any foreign government or taxing authority or subdivision thereof, or

(b) Exclusions from General Tax Indemnity. Each of the following shall constitute an Excluded Tax for purposes of Section 12.2(a)(1), and the provisions of Section 12.2(a)(2) shall not apply to, and the Lessee shall have no liability to a Tax Indemnitee under Section 12.2(a)(2) with respect to:

(1) Taxes (other than such Taxes that are sales, use, rental, property, stamp, document filing, license, ad valorem, value added, franchise, privilege, doing business Taxes or Taxes imposed by way of withholding on the gross income of a Tax Indemnitee) imposed on a Tax Indemnitee that are capital gains Taxes, excess profits Taxes, minimum and/or alternative minimum Taxes, accumulated earnings Taxes, personal holding company Taxes, succession Taxes, estate Taxes, or Taxes imposed on, based on or measured by, gross or net income, receipts, capital, or net worth of such Tax Indemnitee which are imposed by the United States or any state, local, or other taxing authority within the United States; provided that this exclusion shall not apply to any increase in Taxes imposed by a jurisdiction to which the Platform, or any portion thereof, is relocated during the Lease Term;

(4) Taxes on a Tax Indemnitee that result from (A) the willful misconduct, gross negligence, or fraud of such Tax Indemnitee (IT BEING THE INTENT OF THE PARTIES THAT THE EXCLUSION IN THIS CLAUSE (4) DOES NOT EXCLUDE INDEMNIFICATION RESULTING FROM SUCH TAX INDEMNITEE’S OWN NEGLIGENCE) or (B) the breach or inaccuracy by such Tax Indemnitee of any of its representations, warranties or covenants and the failure to perform or observe any agreement under the Operative Documents, unless any such breach, inaccuracy or failure is caused by or results from any act, failure to act, or breach of representation, warranty, or covenant by any Lessee Person or any other party to the Operative Documents or the Joint Operating Agreement;

(5) Taxes on a Tax Indemnitee that result from (A) the failure of such Tax Indemnitee to file tax returns properly and on a timely basis or to claim a deduction or credit to which it is entitled or (B) the failure of such Tax Indemnitee to comply with certification, reporting or other similar requirements of the jurisdiction imposing such Tax; provided, however, that the exclusions set forth in subclauses (A) and (B) shall not apply if any such failure is the result of (x) the failure of the Lessee to (I) perform its obligations under Section 12.2(c) or to perform its duties and responsibilities pursuant to any of the Operative Documents or the Joint Operating Agreement, (II) timely and properly notify such Tax Indemnitee of the applicable filing, certification, reporting or other similar requirements (including the availability of any deduction or credit other than with respect to any Taxes described as not indemnifiable in Section 12.2(b)(1)), or (III) provide reasonable assistance in complying with any such requirement; or (y) a determination by the Owner Participant in good faith that taking any action required in clause (A) in order to obtain a deduction or credit or (B) of this subsection, and in either case, which action is not otherwise required by law could result in any unindemnified adverse consequences or risk of unindemnified adverse consequences to the Lessor, the Lessor Trustee, the Trust Estate, or the Owner Participant or its respective Affiliates, officers, directors, agents or employees;

(17) To the extent indemnified under Section 12.1(a)(vii), Taxes resulting from any violation of ERISA or Section 4975 of the Code; or

(18) any Tax imposed by way of withholding on the gross income of a Tax Indemnitee by a U.S. federal, state or local jurisdiction unless, and to the extent, such Tax is attributable to (i) the Lessee, any Person acting on behalf of the Lessee, or any person using the Undivided Interest (other than the Owner Participant or the Lessor) or relocating the Platform, or any portion thereof, to such jurisdiction; (ii) the Platform’s location on the Closing Date if other than the location certified by the Lessee on the Closing Date; or (iii) a change in applicable treaty or law on or after the closing Date; provided that this exclusion shall not apply to Taxes (i) that are sales, use, rental, property, stamp, document filing, license, ad valorem, value added, franchise or doing business Taxes or (ii) which are imposed upon a Tax Indemnitee (A) which acquired its interest in the overall transaction contemplated by the Operative Documents pursuant to a transfer from a Tax Indemnitee during the existence of a Lease Event of Default or (B) as the result of a Lease Event of Default.

If the Lessee is required to pay any indemnity hereunder on an After-Tax Basis, none of the exclusions in Section 12.2(b)(1) through (18) above shall be read to exclude any Taxes that are necessary to pay such indemnity on an After-Tax Basis. Notwithstanding anything contained herein or any other Operative Document to the contrary, Lessee acknowledges and agrees to indemnify and hold harmless the Owner Participant, the Lessor and the Lessor Trustee (in their respective trust and individual capacities) on an After-Tax Basis against any and all withholding Taxes (inclusive of any interest and penalties imposed for any failure to timely withhold such Taxes) imposed on or with respect to any amounts paid to a Loan Participant or any successor, assignee or Affiliate thereof, as an indemnified Tax for purposes of this Section 12.2, unless such withholding is a result of the Owner Participant, the Lessor or the Lessor Trustee not being a United States person for United States federal income tax purposes. If a Tax (including any related interest, fines, penalties or addition to Tax) (other than, in the case of the Owner Participant, the Lessor and the Lessor Trustee, withholding taxes referred to in the previous sentence) results from a breach or inaccuracy of any Tax Indemnitee of any of its representations, warranties or covenants, or the failure to perform or observe any agreements under the Operative Documents, unless, in the case of the Owner Participant and its respective Affiliates, officers, directors, agents and employees, any such breach, inaccuracy or failure is caused by or results from any act, failure to act or breach of representation, warranty or covenant, or the failure to perform any agreement of any Lessee Person or any other party to the Operative Documents or the Joint Operating Agreement and the Lessee is required to indemnify

Participation Agreement

another Tax Indemnitee against the imposition of such Tax, then the Tax Indemnitee whose breach or failure resulted in the imposition of such Tax shall, within 30 days after receipt of notice of payment of the Tax and appropriate payment documentation with respect thereto, pay to the Lessee an amount which equals the amount paid by the Lessee with respect to or as a result of such Tax. Notwithstanding any provision of the Operative Documents to the contrary, the Lessee agrees (i) to indemnify and hold harmless each Tax Indemnitee on an After-Tax Basis for any Taxes imposed by any United States federal, state or local jurisdiction or by any non-United States jurisdiction in connection with, resulting from or that would not have been imposed but for the removal of the Platform or any portion thereof from United States territorial waters during the Lease Term, whether or not such removal is permitted by the Operative Documents; and (ii) to indemnify the Owner Participant against income, franchise and withholding taxes (other than such taxes imposed by the U. S. Internal Revenue Code) imposed by (x) any jurisdiction to which the Platform is relocated after the Closing Date and (y) any jurisdiction in which the Platform is located on the Closing Date if other than the location certified by the Lessee on the Closing Date, in the case of either (x) or (y) only to the extent of the excess of such taxes imposed by such jurisdiction over the amount that would have been imposed by such jurisdiction had the Platform not been in such location.

The provisions of this Section 12.2(b) shall not apply to any Taxes imposed in respect of the receipt or accrual of any payment made by the Lessee pursuant to Section 12.1 hereof, this Section 12.2 or pursuant to the Tax Indemnity Agreement.

(c) Reports. If any report, return, certification or statement is required to be filed with respect to any Tax that is subject to indemnification under this Section 12.2, the Lessee shall timely prepare and file the same (except for (i) any report, return or statement relating to any net income Taxes described in Section 12.2(b)(1), except that, in such case, the Lessee shall timely provide information necessary to file such report, return or statement (but only to the extent the Lessee collects and maintains such information in the ordinary course of its operations if the relevant Tax Indemnitee otherwise collects and maintains such information in the ordinary course of its operations) or (ii) any other report, return, certification or statement which the Tax Indemnitee has notified the Lessee that the Tax Indemnitee intends to prepare and file); provided that such Tax Indemnitee shall have furnished the Lessee, at the Lessee’s expense, with such information reasonably necessary to prepare and file such returns as is within such Tax Indemnitee’s control. The Lessee shall either file such report, return, certification or statement (so as to show the ownership of the Undivided Interest for tax purposes in the Owner Participant or the Lessor, as applicable) and send a copy of such report, return, certification or statement to the Owner Participant and the Lessor, or, where not so permitted to file, shall notify the Owner Participant and the Lessor of such requirement within a reasonable period of time prior to the due date for filing (without regard to any applicable extensions) and prepare and deliver such report, return, certification or statement to the Owner Participant and the Lessor. In addition, within a reasonable time prior to the time such report, return, certification or statement is to be filed the Lessee shall, to the extent permitted by law, cause all billings of such Taxes to be made to each Tax Indemnitee in care of the Lessee, make payment thereof and furnish written evidence of such payment. The Lessee shall furnish promptly upon written request such data, records and documents as any Tax Indemnitee may reasonably require of the Lessee to enable such Tax Indemnitee to comply with requirements of any taxing jurisdiction arising out of such Tax Indemnitee’s participation in the transactions contemplated by this Agreement, including, without limitation, requirements relating to Taxes described in Section 12.2(b)(1).

Participation Agreement

(d) Payments. Any Tax indemnified hereunder shall be paid directly when due to the applicable taxing authority if direct payment is permitted, or shall be reimbursed to a Tax Indemnitee on demand if paid by such Tax Indemnitee in accordance herewith. Except as otherwise provided in this Section 12.2, all amounts payable to a Tax Indemnitee hereunder shall be paid promptly in immediately available funds, but in no event later than the later of (i) 10 Business Days after the date of such demand or (ii) 3 Business Days before the date the Tax to which such amount payable hereunder relates is due or is to be paid (ignoring extension of time) and shall be accompanied by a written statement (which written statement shall, at the Lessee’s request, as long as payment is not delayed, be verified by a nationally recognized independent accounting firm mutually acceptable to the Lessee and the Tax Indemnitee, such verification to be at the Lessee’s expense unless such accountants determine that the amount payable by the Lessee is less than 90 percent of the amount shown on such written statement, in which event such expense will be paid by the Tax Indemnitee) describing in reasonable detail the Tax and the computation of the amount payable. In the case of a Tax subject to indemnification under this Section 12.2 which is properly subject to a contest in accordance with Section 12.2(e), the Lessee (1) shall be obligated to make any advances with respect to such Tax whenever required under Section 12.2(e) and (ii) shall pay such Tax (in the amount finally determined to be owing in such contest) on an After-Tax Basis prior to the latest time permitted by the relevant taxing authority for timely payment after a Final Determination.

(e) Contests; Refunds. (i) In the event a taxing jurisdiction makes a claim with respect to any Tax for which the Lessee is liable under this Section 12.2 (a “Tax Claim”), the Lessee may cause the applicable Tax Indemnitee to contest such Tax Claim as set forth herein. In the event any Tax Indemnitee receives notice of a Tax Claim or potential Tax Claim which is indemnifiable under this Section 12.2, such Tax Indemnitee (i) shall promptly notify the Lessee thereof, but the failure to give such notice shall not diminish the Lessee’s obligation hereunder, except to the extent that the Lessee’s right to contest such Tax Claim or potential Tax Claim is foreclosed thereby and (ii) shall not take any action with respect to such Tax Claim or potential Tax Claim without the consent of the Lessee for 30 days after notifying the Lessee unless the failure to take action could result in the imposition of penalties or fines or material danger of sale, forfeiture or loss of, or the creation of any Lien on, the Platform or the Undivided Interest or any portion thereof or interest therein. If requested by the Lessee in writing within 30 days of receipt of such notice (or, if sooner, on or before the last date upon which the contest of such Tax can practicably be initiated in good faith, provided that the Tax Indemnitee’s notice to the Lessee discloses such date), such Tax Indemnitee shall, provided that (I) it has received an indemnity satisfactory to it whereby the Lessee shall have agreed to pay and shall pay to such Tax Indemnitee on an After-Tax Basis all reasonable costs, expenses, losses, legal and accountants’ fees and disbursements, and all penalties, fines, additions to tax and interest in connection with contesting such Tax Claim and (II) no Lease Event of Default or Lease Default described in Section 15 (a), (b), (c), (f) or (g) of the Lease shall have occurred and be continuing, and at the expense of the Lessee, contest or permit the Lessee to contest the imposition of any Tax Claim by (1) resisting payment thereof, if such Tax Indemnitee in its reasonable discretion determines that there is a reasonable basis for doing so, (2) not paying the same except under protest, if protest is necessary and proper, or (3) if payment shall be made, using reasonable efforts to

Participation Agreement

obtain a refund thereof in appropriate administrative and judicial proceedings; provided, however, that (i) in no event will such Tax Indemnitee be required to contest or permit a contest or continue to contest any Tax Claim unless such Tax Indemnitee and the Owner Participant shall have reasonably determined that the action to be taken will not result in (a) any material risk of sale, forfeiture or loss of, or the creation of any lien (except if the Lessee shall have adequately bonded such lien, or otherwise made provision to protect the interests of such Tax Indemnitee and the Owner Participant in a manner reasonably satisfactory to such Tax Indemnitee and the Owner Participant) on, the Platform, the Undivided Interest, any part thereof or interest therein or (b) any risk of criminal penalties and (ii) if such contest shall involve payment of the Tax Claim, the Lessee shall have advanced to such Tax Indemnitee the amount of such payment plus interest, penalties and additions to tax with respect thereto on an interest-free basis, and shall indemnify the Tax Indemnitee, on an After-Tax Basis, for any adverse tax consequences resulting from such advance. If permitted by applicable law, the Lessee may contest, at its own expense, the imposition of any Tax Claim if (i) the provisos in the preceding sentence are satisfied, (ii) the Lessee shall have delivered to the Tax Indemnitee a written acknowledgment of its liability under this Section 12.2 for such Taxes (provided, however, that the Lessee will 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 the Lessee has no liability under this Section 12.2 with respect to such Tax, unless the Lessee’s conduct of the contest has materially prejudiced the Tax Indemnitee), (iii) the participation of the Tax Indemnitee is not required, (iv) no Tax return of the Tax Indemnitee is held open as a result of such contest, (v) the Tax Indemnitee may not be reasonably viewed as having actual or potential liability for Taxes not indemnifiable by the Lessee hereunder relating to the contest (vi) the Tax Indemnitee has determined in good faith that permitting the Lessee to control such contest will not otherwise materially adversely affect the business affairs of the Tax Indemnitee and (vii) such contest does not involve a Tax Claim with respect to net income Taxes, franchise Taxes or Taxes imposed by way of withholding. In no event shall a Tax Indemnitee be required to appeal an adverse judicial determination to the United States Supreme Court. In any contest controlled by a Tax Indemnitee, the Tax Indemnitee shall consult in good faith with the Lessee concerning the method and forum of such contest, but the Tax Indemnitee shall retain the ultimate control over such contest. The Lessee shall have control over any contest conducted by the Lessee pursuant to the terms hereof but shall consult in good faith with the Tax Indemnitee concerning the method and forum of such contest. The Lessee shall keep the Tax Indemnitee fully informed as to the nature, conduct and results of any contest conducted in the name of the Tax Indemnitee. Notwithstanding anything contained in this Section 12.2 to the contrary, no Tax Indemnitee shall be required to contest any Tax Claim unless such Tax Indemnitee shall have received an opinion of such independent tax counsel as may be selected by the Lessee and reasonably acceptable to the Tax Indemnitee, furnished at the Lessee’s sole expense, to the effect that there is a reasonable basis for the Tax Indemnitee to contest such Tax Claim. A Tax Indemnitee shall not make, accept or enter into a settlement or other compromise with respect to any Taxes indemnified pursuant to this Section 12.2 (which proceeding the Tax Indemnitee is required to continue), or forego or terminate any such proceeding with respect to Taxes indemnified pursuant to this Section 12.2, without the prior written consent of the Lessee provided that the Lessee shall have acknowledged that the contest is with respect to a Tax Claim that would result in a Tax indemnifiable under this Section 12.2. Notwithstanding the foregoing, if a Tax Indemnitee refuses to contest any Tax Claim or effects a settlement or compromise of

Participation Agreement

any such Tax that the Tax Indemnitee is required to contest or is required not to settle or compromise or otherwise terminates any such contest in violation of the terms hereof without such prior written consent of the Lessee (but not with respect to any reasonable out-of-pocket costs and expenses incurred by the Tax Indemnitee to contest such Tax Claim), such Tax Indemnitee shall be deemed to have waived its right to any indemnity payment by the Lessee that would otherwise be payable by the Lessee pursuant to this Section 12.2 in respect of such Tax Claim and any other tax claim the contest of which may be effectively precluded by such settlement or compromise, and shall have no further obligation or liability to the Lessee with respect to such contest or settlement. Notwithstanding anything contained in this Section 12.2 to the contrary, the Tax Indemnitee shall not be required to contest any claim if the subject matter thereof shall be of a continuing nature and shall have previously-been decided adversely by a court of competent jurisdiction pursuant to the contest provisions of this Section 12.2, unless there shall have been a change in law (or interpretation thereof) or a change in facts after the date with respect to which such previous contest shall have been decided, and the Tax Indemnitee shall have received, at the Lessee’s expense, an opinion of independent tax counsel selected by the Lessee and reasonably acceptable to such Tax Indemnitee to the effect that as a result of such change in law (or interpretation thereof) or a change in facts, there is substantial authority (applying the principles of Section 6662 (d) of the Code and the Treasury Regulations thereunder) for the position asserted by the Tax Indemnitee in such contest.

(ii) Upon receipt by any Tax Indemnitee of a repayment or refund of all or any part of any Tax which the Lessee shall have paid for, or advanced to, such Tax Indemnitee or for which the Lessee shall have reimbursed such Tax Indemnitee pursuant to this Section 12.2, such Tax Indemnitee shall pay to the Lessee, as promptly as practicable after the receipt thereof, the amount of such repayment or refund plus any interest received by, or credited to, such Tax Indemnitee on such amounts net of Taxes thereon plus the amount of any net tax savings actually realized by such Tax Indemnitee as a result of the payment made to the Lessee; provided, however, that: (A) such Tax Indemnitee shall not be obligated to make such payment with respect to any net tax savings to the extent that the amount of such payment would exceed (x) all prior indemnity payments (excluding costs and expenses incurred with respect to contests) made by the Lessee with respect to such Tax pursuant to this Section 12.2 and less (y) the amount of all prior payments by such Tax Indemnitee to the Lessee hereunder with respect to such Tax (but any such excess shall be applied against, and reduce pro tanto, any future payment due such Tax Indemnitee pursuant to this Section 12.2); (B) if there is (1) a subsequent loss of any such tax savings or refund realized by the Tax Indemnitee or (2) a reduction of an amount otherwise payable to a Tax Indemnitee hereunder as a result of any such tax savings or refund, such loss or reduction shall be treated as a Tax for which the Lessee must indemnify such Tax Indemnitee pursuant to this Section 12.2 without regard to the exclusions set forth in Sections 12.2(b) and 12.2(c), other than the exclusions set forth in Sections 12.2(b)(4)(A), (7) and (13); and (C) no payment shall be made by any Tax Indemnitee while a Lease Event of Default shall have occurred and be continuing.

(f) Tax Savings. If, by reason of any payment made to or for the account of a Tax Indemnitee by the Lessee pursuant to this Section 12.2, such Tax Indemnitee at any time realizes a reduction in any Taxes for which the Lessee is not required to indemnify such Tax Indemnitee

pursuant to this Section 12.2 and which was not taken into account previously in computing such payment by the Lessee to or for the account of such Tax Indemnitee, then such Tax Indemnitee shall promptly pay to the Lessee an amount equal to such actual reduction in Taxes, plus the amount of any additional reduction in Taxes of such Tax Indemnitee attributable to the payment made by such Tax Indemnitee to the Lessee pursuant to this sentence. Notwithstanding the previous sentence, (A) such Tax Indemnitee shall not be obligated to make such payment with respect to any net tax savings to the extent that the amount of such payment would exceed (x) all prior indemnity payments (excluding costs and expenses incurred with respect to contests) made by the Lessee with respect to such Tax pursuant to this Section 12.2 and less (y) the amount of all prior payments by such Tax Indemnitee to the Lessee hereunder with respect to such Tax (but any such excess shall be applied against, and reduce pro tanto, any future payment due such Tax Indemnitee pursuant to this Section 12.2); (B) if there is a (i) subsequent loss of any such tax savings or refund realized by the Tax Indemnitee or any tax savings taken into account for purposes of determining “After-Tax Basis” or (ii) a reduction of an amount otherwise payable to a Tax Indemnitee hereunder as a result of any such tax savings or refund, such loss or reduction shall be treated as a Tax for which the Lessee must indemnify such Tax Indemnitee pursuant to this Section 12.2 without, regard to the exclusions set forth in Sections 12.2(b) and 12.2(c), other than the exclusions set forth in Sections 12.2(b)(4)(A), (7) and (13); and (C) no payment shall be made by any Tax Indemnitee while a Lease Event of Default shall have occurred and be continuing.

(g) Definition of Owner Participant. For purposes of this Section 12.2, the term “Owner Participant” and the term Tax Indemnitee as applied to the Owner Participant shall include any member of an affiliated group, within the meaning of Section 1504 of the Code (or any successor provision thereof), of which the Owner Participant is, or may become, a member, if consolidated, joint or combined returns are filed for such affiliated group for federal, state or local income tax purposes. The Owner Participant undertakes on behalf of such other members of its affiliated group to perform or cause to be performed all obligations of such affiliated group hereunder.

12.3 No Guaranty. Nothing in Section 12.1 or 12.2 shall be construed as a guaranty by the Lessee of the useful life or residual value in the Undivided Interest or as a guaranty of the Notes.

SECTION 13

(b) no such transfer shall violate any provision of, or create a relationship which would be in violation of, any applicable Governmental Rules, including, without limitation, applicable securities laws, any agreement to which the Owner Participant or the Transferee is a party or by which it or any of its property is bound or any Governmental Actions;

Upon any transfer by the Owner Participant in accordance with this Section 13, the Transferee shall be deemed an “Owner Participant” for all purposes of the Operative Documents and each reference herein to the Owner Participant making such transfer shall thereafter be deemed a reference to such Transferee for all purposes.

Any transfer that is not in accordance with this Section 13 shall be a breach of this Agreement and shall be null and void; provided that the failure by the transferring Owner Participant to provide 10 Business Days prior written notice of a transfer in accordance with Section 13.2(d) shall not constitute a breach of this Agreement if such failure is cured within 5 days after the earlier of receipt by the Owner Participant of written notice thereof from the

SECTION 16

BENEFICIAL INTEREST PURCHASE OPTION

16.1 Option to Purchase. In the event and at the time that the Lessee has the right to purchase all of Lessor’s right, title and interest in and to the Undivided Interest pursuant to Section 6.1(b) of the Lease, the Lessee in lieu of consummating such purchase may elect to purchase (or cause its designee (which may be an Affiliate of the Lessee) to purchase) the right,

Participation Agreement

title and interest of the Owner Participant in and to the Trust Estate (the “Beneficial Interest”) at a purchase price equal to the excess of (a) the applicable purchase price payable under Section 6.1(b) of the Lease, over (b) the outstanding principal and accrued interest on the Notes as of the applicable purchase date (after giving effect to the payment of all amounts required to be paid by the Lessee pursuant to Section 16.2(b)) (the “Beneficial Interest Purchase Price”). It is intended among the parties hereto that the purchase of the Beneficial Interest by the Lessee (or its designee, which may be an Affiliate of the Lessee) shall not effect a merger of the Lessee’s interest, as lessee, in the Lease and the beneficial interest in the Trust Estate to be purchased by the Lessee. Such purchase shall be consummated pursuant to an assignment and assumption agreement, to be mutually agreed upon by the Lessee, as purchaser, and Owner Participant, as seller, including provisions which shall at a minimum preserve the Owner Participant’s rights which are expressly stated to survive any purchase and terminate as of the effective date thereof all of the Owner Participant’s obligations which are not expressly stated in such assignment and assumption agreement to survive such purchase and shall provide, in a manner in form and substance satisfactory to the Owner Participant, for the complete release of the Owner Participant from all of its obligations under the Operative Documents.

16.2 Notice of Election; Manner of Purchase, Transfer After Purchase. (a) In order to exercise its right to purchase (or cause a designee to purchase) the Beneficial Interest pursuant to Section 16.1, the Lessee shall notify the Owner Participant, the Loan Participants and the Indenture Trustee irrevocably in writing no later than 30 days prior to the applicable purchase date under Section 6.1 of the Lease that it desires to purchase the Beneficial Interest.

(b) On the date of purchase, upon receipt by the Owner Participant of the Beneficial Interest Purchase Price, and all other amounts due or distributable to the Owner Participant on or prior to such date of purchase (without giving effect to any applicable grace periods), the Owner Participant shall transfer the Beneficial Interest, free and clear of all Owner Participant’s Liens and all Lessor’s Liens described in Section 11.1(a)(ii), to the Lessee (or its designee) pursuant to an instrument of conveyance in form and substance reasonably satisfactory to the Owner Participant and the Lessee.

(c) Each of the Participants, the Lessor, the Lessor Trustee and the Indenture Trustee, at the expense of the Lessee, will cause to be promptly and duly taken, executed, acknowledged and delivered all such further acts, documents and assurances as the Lessee may reasonably request in order to carry out the intent and purposes of this Section 16 and the transactions contemplated hereby.

(d) As a condition to the Lessee’s right to purchase (or cause its designee to purchase) the Beneficial Interest pursuant to Section 16.1 (unless the Lessee shall assume the obligations of the Lessor pursuant to the next sentence), on the date of purchase the Lessee shall have provided to the Indenture Trustee an opinion of counsel, dated the date of purchase, which, subject to usual or customary exceptions, shall be to the effect that upon consummation of such purchase, this Agreement, the Trust Agreement and the Lease constitute the legal, valid and binding obligation of the Lessee, enforceable against the Lessee in accordance with its terms except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors generally and by general principles of equity, and except as limited by applicable laws that may affect the remedies provided for in the Lease,

Participation Agreement

which laws, however, do not in the opinion of such counsel make the remedies provided for in the Lease inadequate for the practical realization of the rights and benefits provided for in the Lease. In the event the Lessee is unable to provide such opinion, concurrently with the purchase of the Beneficial Interest the Lessee shall assume the obligations of the Lessor in respect of the Notes and under the Indenture in accordance with and with the effect provided in Section 3.04 of the Indenture and Section 11.6 hereof.

Capitalized terms used but not defined herein have the meanings set forth in Appendix A to the Participation Agreement.

1. Pursuant to Section 13.2(d) of the Participation Agreement, notice is hereby given that, effective upon satisfaction of the applicable conditions to transfer set forth in Section 13 of the Participation Agreement and any additional conditions agreed to by Transferor and Transferee (each as defined below) (the date upon which such conditions have been satisfied is hereinafter referred to as the “Effective Date”), the undersigned (“Transferor”) hereby sells, assigns, conveys, transfers and otherwise sets over unto (together with its successors and permitted assigns, “Transferee”), and Transferee hereby unconditionally purchases from Transferor all of Transferor’s present and future right, title and interest in and to the Participation Agreement, the Tax Indemnity Agreement and the other Operative Documents to which Transferor is a party (collectively, the “Equity Agreements”) and to the Trust Estate and Undivided Interest and any proceeds therefrom, reserving to Transferor (but not to the exclusion of Transferee), however, all Transferor’s rights as an Indemnitee. The rights so transferred collectively are called the “Transferred Interest”.

2. Transferor and Transferee hereby confirm that upon such transfer, (a) Transferee assumes and undertakes, and covenants and agrees that it will pay, perform and discharge, all of the duties and obligations of the Owner Participant arising or accruing on or after the Effective Date with respect to the Transferred Interest (thereby excluding any duties or obligations required to be performed by Transferor before the Effective Date) under the Equity Agreements and any of the other Operative Documents by which the Owner Participant is bound, and (b) Transferee shall be entitled to all rights and benefits of the Owner Participant with respect to such Transferred Interest under the Operative Documents as though Transferee had been the Owner Participant as of the execution and delivery of Transferor of the Trust Agreement (the “Delivery Date”), other than with respect to rights and benefits properly allocable to the period between the Delivery Date and the Effective Date.

Participation Agreement

3. Transferee hereby confirms that, on and after the Effective Date, it shall be deemed a party to each of the Equity Agreements, and that it shall be bound thereby as if therein named as “Owner Participant” with respect to the Transferred Interest.

As between Transferor and Transferee, on the Effective Date, Transferor will be relieved of and Transferee will thereupon assume all obligations of Transferor with respect to the Transferred Interest (other than with respect to obligations properly allocable to the period between the Delivery Date and the Effective Date).

4. In furtherance of the transfer effected by this Assignment and Assumption Agreement, Transferor hereby constitutes and appoints Transferee its true and lawful attorney, with full power of substitution, in the name of Transferee or in the name of Transferor but on behalf of, for the benefit of and at the expense of Transferee: (a) to collect for the account of Transferee all items sold, assigned, conveyed, transferred or otherwise set over to Transferee pursuant to this Assignment and Assumption Agreement, (b) to institute and prosecute, in the name of Transferor or otherwise, but at the expense of Transferee, all proceedings that Transferee deems proper in order to collect, assert or enforce any claim, right or title of any kind in or to the items so sold, assigned, conveyed, transferred or otherwise set over, (c) to defend and compromise at the expense of Transferee any and all actions, suits or proceedings as to the title or interest in all or any portion of the Transferred Interest, and (d) to do all such acts and things in relation thereto at the expense of Transferee as Transferee reasonably deems advisable. Transferor hereby acknowledges that this appointment is coupled with an interest and is irrevocable by Transferor in any manner or for any reason or by virtue of any dissolution of Transferor.

5. Transferor hereby covenants and agrees promptly to pay over to Transferee any amounts (including any sums payable as interest in respect thereof) received by it that, under paragraph 1, have been assigned to Transferee, and Transferee hereby covenants and agrees promptly to pay over to Transferor any amounts (including any sums payable as interest in respect thereof) received by it that, under paragraph 1, have not been assigned by Transferor to Transferee.

6. Each party hereto agrees that it shall, at the expense of the party requesting the same, at any time and from time to time, promptly and duly execute and deliver any and all further instruments and documents and take such further action that reasonably may be required in order to obtain the full benefits of this Assignment and Assumption Agreement and to implement the rights and powers herein granted.

7. Transferor hereby represents and warrants that it has, and by this Assignment and Assumption Agreement does convey to Transferee, all right, title and interest originally acquired by it in the Transferred Interest, free and clear of any Owner Participant’s Liens.

8. Transferee hereby represents that it is acquiring the Transferred Interest and the other rights, titles and interests hereby transferred to it, for its own account for the purpose of investment and not with a view to, or for the sale in connection with, any distribution of any such interest; except that Transferee reserves the right to transfer or assign all of the Transferred Interest to the extent permitted by the Participation Agreement.
