The obligation to provide indemnities in accordance with the terms of this Section 12.1 shall survive the termination of the Lease. (b) Notices. If the Lessee shall obtain knowledge of any action, suit, proceeding or written notice of any Claim indemnified against under this Section 12.1, the Lessee shall give prompt notice thereof to the appropriate Indemnitee or Indemnitees, as the case may be, and if any Indemnitee shall obtain any such knowledge, such Indemnitee shall give prompt notice thereof to the Lessee provided that the failure of such Indemnitee to so notify the Lessee shall not affect the Lessee's indemnification obligations under this Section 12.1 to such Indemnitee except to the extent of any increase in the amount of such Claim resulting from such failure or to the extent the Lessee is effectively precluded from contesting such Claim as a result of such failure. (c) Contests. Subject to the rights of insurers under policies of insurance maintained pursuant to Section 13 of the Lease, the Lessee shall have the right, at its sole cost and expense, to investigate, and the right in its sole discretion to defend or contest by appropriate proceedings or compromise, any Claim for which indemnification is sought under this Section 12.1, and the Indemnitee shall cooperate, at the Lessee's expense, with all reasonable requests of the Lessee in connection therewith, provided that the Lessee shall not have the right without the consent of the Indemnitee to defend, contest or compromise any claim with respect to such Indemnitee (i) if a 63 Lease Event of Default shall have occurred and be continuing, (ii) if such proceeding involves any material danger of the sale, forfeiture or loss of the Undivided Interest, or (iii) if such Claim involves a realistic possibility of criminal sanctions or criminal liability to such Indemnitee, in which event the Indemnitee shall be entitled to control and assume responsibility for the defense of such Claim at the expense of the Lessee. The Lessee will not be required to acknowledge liability as a condition to exercising its contest rights hereunder unless the Lessee assumes control of such contest. With respect to any Claim, liability for which the Lessee shall have acknowledged to the relevant Indemnitee in writing, in the event that in the course of the investigation or defense of such Claim, the Lessee shall in good faith reasonably determine that it is not liable for indemnification with respect thereto, it may give notice to the applicable Indemnitee of such fact; and, in such case, any acknowledgement therefore made by the Lessee of its liability with respect to such Claim shall be deemed revoked, and the Lessee may thereupon cease to defend such Claim, provided that (i) it shall have given the Indemnitee reasonable prior notice of its intention to renounce such acknowledgment, (ii) the Lessee's conduct regarding the defense of such Claim or any decision to withdraw from such defense shall not materially prejudice or have materially prejudiced the Indemnitee's ability to contest such Claim (taking into account, among other things, the time of the Lessee's withdrawal and the theory or theories upon which the Lessee shall have based its defense), and (iii) the Lessee shall have given such Indemnitee all materials, documents and records relating to its defense of such Claim as such Indemnitee shall have reasonably requested in connection with the assumption by such Indemnitee of the defense of such Claim at the cost and expense of such Indemnitee unless it is determined that the Lessee is required to indemnify such Indemnitee for such Claim, in which case 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 Indemnitee 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 Indemnitee to incur any loss, cost, liability or expense which such Indemnitee might not have incurred had the Lessee not ceased to defend such Claim in such manner or such time; provided, however, that the Lessee shall not be required to indemnify such Indemnitee to the extent that the Lessee shall have proven (in a judicial proceeding or otherwise) that neither its manner of defending such Claim nor the manner of time of its withdrawal from the defense of such Claim caused such loss, cost, liability or expense. 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 64 otherwise cooperate with such Indemnitee so as to enable such Indemnitee to investigate or defend any Claim. The Lessee 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 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 such Indemnitee shall reasonably request. Where 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 written opinion of counsel to such Indemnitee an actual or potential material 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 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 Lease Event of Default, the Lessee shall not compromise any Claim without the consent of the applicable Indemnitee unless such Claim is simultaneously discharged, such consent not to be unreasonably withheld. Notwithstanding anything to the contrary contained in this Section 12.1, to the extent the defense or settlement of any Claim in respect of which an Indemnitee is entitled to indemnification hereunder is governed by the terms of the Operating Agreement, such defense or settlement shall be governed by the Operating Agreement; provided, that the defense or settlement of such Claim in accordance with the 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 65 respect of the matters against which such indemnity was given (other than claims under any insurance policies maintained by such Indemnitee). Such Indemnitee agrees to cooperate with the Lessee and to execute such further instruments to permit the Lessee, at the Lessee's expense, to pursue such claims, to the extent reasonably requested by the Lessee. (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 for 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 any interest received by such Indemnitee on such amount 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) Payments; Verification. Any amount payable to any Indemnitee pursuant to this Section 12.1 shall be paid to such Indemnitee promptly upon receipt of a written demand therefor from such Indemnitee, accompanied by a written statement describing the basis for such indemnity and the computation of the amount so payable and, if requested by the Lessee, such determination shall be verified by a nationally recognized independent accounting firm mutually acceptable to the Lessee and the Indemnitee at the Lessee's expense, unless such accounting firm determines that the amount payable by the Lessee is less than 95 percent (95%) of the amount shown on such written statement, in which case such verification shall be at such Indemnitee's expense. 12.2 General Tax Indemnification. (a)(i) 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 of any nature whatsoever, and in the event that the Lessee shall be required by applicable law to make any such withholding for any such payment, (x) Basic 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 such withholdings and (z) the Lessee shall pay the full amount withheld to the relevant taxing authority in accordance with applicable law. If for any reason, the Lessee is required to make any payment to a taxing authority or to any Tax Indemnitee as a result of the application of the preceding sentence or otherwise that relates to or is a result of any Tax imposed on or 66 with respect to any Tax Indemnitee which Tax (in whole or in part) is an Excluded Tax under the terms of Section 12.2(b), then the Tax Indemnitee in respect of whom such Tax is an Excluded Tax hereunder 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 Excluded Tax (including any expenses or other charges borne by the Lessee) increased by (but subject to the proviso in Section 12.2(f)) the amount of tax savings to such Tax Indemnitee attributable to the making of such payment to the Lessee. 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. (ii) 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 any international taxing authority or any subdivision or taxing authority of any thereof (all the foregoing being herein collectively called "Taxes" or, separately, a "Tax"), upon or with respect to (i) the Undivided Interest or any portion thereof or interest therein, (ii) the acquisition, purchase, sale, financing, leasing, subleasing, sub-subleasing and sub-sub-subleasing, ownership, maintenance, repair, redelivery, alteration, insuring, control, use, operation, manufacture, assembly, delivery, possession, repossession, location, storage, importation, exportation, refinancing, refunding, transfer of title, registration, reregistration, transfer of registration, return or other disposition thereof of all or any part of the Undivided Interest or any portion thereof or interest therein, (iii) the rental payments (including, without limitation, all Basic Rent and Supplemental Rent), receipts or earnings arising from the Undivided Interest or any portion thereof or interest therein, or payable pursuant to the Lease, or any other payment or right to receive payment pursuant to the Operative Documents or the Pass Through Trust Agreement or Pass Through Certificates 67 (including, without limitation, any payment of principal, interest, discount or premium on or with respect to the Secured Notes), (iv) any Modification or replacement, removal, substitution or repair of a Component or Replacement Component, (v) the Operating Agreement or the Operative Documents and any other documents contemplated hereby or thereby and amendments and supplements thereto, or the issuance, refunding, refinancing or resetting of the Secured Notes or the Pass Through Certificates or any other document executed and delivered in connection with the consummation of the transactions contemplated by the Operative Documents or the Pass Through Trust Agreement or the interest of any Tax Indemnitee in any of the foregoing, or the execution, amendment, issuance or delivery of any of the foregoing, (vi) the Indenture Estate or Trust Estate or Pass Through Trusts or the property, or the income or other proceeds received with respect to the property, held by the Indenture Trustee under the Indenture or the Grantor Trustee under the Trust Agreement, or (vii) otherwise arising out of, with respect to, or in connection with the transactions contemplated by the Operating Agreement or the Operative Documents, the Pass Through Certificates, or the Pass Through Trust Agreement. (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 on a Tax Indemnitee (other than such Taxes that are sales, use, rental, property, stamp, document filing, license, or ad valorem Taxes, or value added Taxes that are in the nature of or in lieu of such Taxes) imposed on a Tax Indemnitee that are franchise Taxes, privilege Taxes, doing business Taxes, capital gains Taxes, excess profits Taxes, minimum and/or alternative minimum Taxes, accumulated earnings Taxes, personal holding company Taxes, succession Taxes, estate Taxes, value added Taxes (imposed in lieu of net income Taxes) or Taxes imposed on, based on or measured by, gross or net income, receipts, capital, or net worth of such Tax Indemnitee (including, without limitation, any such Taxes collected by withholding) which are imposed by any state, local, or other taxing authority within the United States or by any foreign or international taxing authority that would not have been imposed but for such Tax Indemnitee having a place of business, being incorporated or organized or being otherwise subject to such Tax, in each case, as a result of transactions or activities unrelated to the transactions contemplated by the Operative Documents, the Operating Agreement or the Pass Through Trust Agreement; 68 (2) Taxes on a Tax Indemnitee, including, without limitation, sales and transfer Taxes, that result from any voluntary or involuntary transfer by such Tax Indemnitee of any interest in the Undivided Interest, the Trust Estate, the Lease or any portion of any of the foregoing, or any interest arising out of the Operative Documents or any Pass Through Trust Agreement or the Secured Notes or Pass Through Certificates; provided, however, that this Section 12.2(b)(2) shall not apply to any transfer that (A) with respect to the Owner Participant, and its respective Affiliates, officers, directors, agents, and employees, occurs after a Lease Event of Default has occurred and is continuing, or, in the case of any other Tax Indemnitee, relates to the exercise of remedies in connection with a Lease Event of Default; (B) results from an Event of Loss or from any other destruction, damage, theft, or governmental taking, confiscation, seizure, or requisition of or to the Production System or any material part thereof that does not yet constitute an Event of Loss; (C) is required by the Operative Documents; (D) is made to the Lessee or another Person at the Lessee's direction; (E) results from the replacement, removal, substitution, or subleasing of all or any part of the Undivided Interest; or (F) occurs on the Closing Date in connection with the consummation of the transactions contemplated by the Operative Documents; (3) Taxes imposed by any jurisdiction on a Tax Indemnitee solely as a result of its activities in such jurisdiction unrelated to the transactions contemplated by the Operative Documents or the Pass Through Trust Agreement; (4) Taxes on a Tax Indemnitee that result from (A) the willful misconduct, gross negligence, or fraud of such Tax Indemnitee, (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 or Pass Through Trust Agreement, 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 by any Lessee Person or any other party to the Operative Documents, the Operating Agreement or the Pass Through Trust 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 Operating Agreement, (II) timely and properly notify such Tax Indemnitee of the applicable filing, certification, reporting or other 69 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)(l)), 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 otherwise required in clause (A) or (B) of this subsection could result in any unindemnified adverse tax consequences or risk of unindemnified adverse tax consequences to the Grantor Trustee, the Trust Estate, or the Owner Participant or its respective Affiliates, officers, directors, agents, or employees, provided that the Owner Participant shall promptly (but, (i) with respect to reports, returns, certifications and statements required to be provided by the Lessee pursuant to Section 12.2(c) hereof, in no event later than 10 Business Days following the date any such item is provided, (ii) with respect to reports, returns and statements relating to Taxes described in Section 12.2(b)(1) hereof that are indemnifiable notwithstanding that section, in no event later than 10 Business Days following the date the Lessee has provided information necessary to file such reports, returns, or statements (but only to the extent the Lessee is required to file such reports, returns or statements hereunder), and (iii) with respect to reports, returns or statements relating to Taxes described in Section 12.2(b)(1) hereof that are not indemnifiable, in no event later than 10 Business Days before the date the reports, returns, or statements are to be filed) provide the Lessee written notice identifying the nature of the unindemnified adverse tax consequences, (and, if the Lessee indemnifies the Grantor Trustee, the Trust Estate or the Owner Participant, as the case may be, and its respective Affiliates, officers, directors, agents and employees promptly for such unindemnified adverse tax consequences in a manner reasonably satisfactory to such Tax Indemnitee (including for credit purposes), the exclusions set forth in subclauses (A) and (B) shall apply; (6) Taxes which are attributable to any period or circumstance occurring after the expiration or earlier termination of the Lease, except to the extent attributable to (A) a failure of the Lessee to fully discharge its 70 obligations under the Operative Documents, (B) Taxes imposed on or with respect to any payments that are due after the expiration or earlier termination of the Lease and which are attributable to a period or circumstance occurring prior to or simultaneously with such expiration or earlier termination; (7) Taxes on the Grantor Trustee, the Indenture Trustee or the Pass Through Trustee which are based on or measured by fees or compensation received by the Grantor Trustee for acting as Grantor Trustee under the Trust Agreement, the Indenture Trustee for acting as Indenture Trustee under the Indenture or the Pass Through Trustee for acting as Pass Through Trustee under the Pass Through Trust Agreement; (8) Taxes on a Tax Indemnitee to the extent such Taxes would not have been imposed if such Tax Indemnitee were a United States person for United States federal income tax purposes; (9) any Tax that is being contested in accordance with the provisions of Section 12.2(e) during the pendency of such contest, but only for so long as such contest is continuing in accordance with such Section and payment is not otherwise required pursuant to such Section; (10) Taxes on a Tax Indemnitee as to which such Tax Indemnitee fails to comply with its contest obligations under Section 12.2(e) but only to the extent such failure precludes a contest and the Lessee has a reasonable basis for such contest; provided, however, that this Section 12.2(b) (10) shall not constitute a waiver by the Lessee of its rights, if any, to assert and sue upon any claims it may have against the Tax Indemnitee by reason of its failure to comply with its obligations under Section 12.2(e) of this Agreement; (11) Taxes imposed as a result of (A) in the case of the Owner Participant, the Grantor Trustee, and their respective Affiliates, officers, directors, agents, and employees, the trust described in the Trust Agreement not being treated as a grantor trust or other conduit entity for federal, state or local tax purposes and (B) in the case of all other Tax Indemnitees, any of the Pass Through Trusts not being treated as a grantor trust or other conduit entity for federal, state, or local tax purposes; (12) any Taxes imposed on a transferee or subsequent transferee to the extent of the excess of such Taxes over the total amount of the Taxes of the same or similar nature 71 that would have been imposed had there not been a transfer by the initial Tax Indemnitee after the Closing Date (except in the case of a transfer by the Owner Participant or the Lessor which is described in clauses (A), (B), (C) or (E) of Section 12.2(b)(2) above) of (i) an interest in the Undivided Interest, or of a beneficial interest in the Trust Estate or any portion of any of the foregoing, or (ii) any interest arising under any Operative Document or any Pass Through Trust Agreement or any Secured Note or Pass Through Certificate; (13) Taxes which have been included in Lessor's Cost; (14) Taxes imposed on a Tax Indemnitee that are United States federal net income Taxes of such Indemnitee including any Taxes which are the subject of the Tax Indemnity Agreement; (15) Taxes imposed on the Grantor Trustee or the Owner Participant resulting from a Lessor's Lien or an Owner Participant's Lien, respectively; (16) Taxes imposed on a Tax Indemnitee resulting from an amendment to an Operative Document to which such Tax Indemnitee is a party which amendment is not consented to by the Lessee in writing or required by the Operative Documents; (17) any Tax (other than a Tax imposed on the Owner Participant or the Grantor Trustee) in the nature of an intangible tax or similar tax upon or with respect to the value of the interest of the Indenture Estate or a Certificateholder, as the case may be, in any of the Secured Notes or Certificates imposed by any government or taxing authority; or (18) Taxes resulting from any violation of ERISA or Section 4975 of the Code. 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 not necessary to pay such indemnity on an After-Tax Basis. Notwithstanding anything contained herein or any other Operative Document to the contrary, the Lessee acknowledges and agrees to indemnify and hold harmless the Owner Participant and Grantor 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 72 Affiliate thereof, as an indemnified Tax for purposes of this Section 12.2, unless such withholding is due to the Owner Participant or the Grantor 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 and the Grantor 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 or the Pass Through Trust Agreement, 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, the Operating Agreement or the Pass Through Trust Agreement, and the Lessee is required to indemnify 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 (including any expenses or other charges borne by the Lessee) increased by (but subject to the proviso in Section 12.2(f)) the amount of tax savings to such Tax Indemnitee attributable to the making of such payment to the Lessee. 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) or any Taxes in lieu of or enacted in substitution for any of the foregoing, (ii) any report, return or statement relating to any other Taxes described in Section 12.2(b)(1) or any Taxes in lieu of or enacted in substitution for any of the foregoing, except that, in such cases, 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 (iii) any other report, return, certification 73 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 Grantor Trustee) and send a copy of such report, return, certification or statement to the Owner Participant and the Grantor Trustee, or, where not so permitted to file, shall notify the Owner Participant and the Grantor Trustee 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 Grantor Trustee. 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). (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) 2 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 ninety-five percent (95%) 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 74 properly subject to a contest in accordance with Section 12.2(e), the Lessee (i) 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 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, unless the Tax Indemnitee delivers an opinion of independent tax counsel that no reasonable basis exists for the Tax Indemnitee to prevail (except if the Lessee shall have provided to the Tax Indemnitee at the Lessee's sole expense an opinion of the Lessee's independent tax counsel, such tax counsel being reasonably acceptable to the Tax Indemnitee, to the effect that a reasonable basis exists for such contest). 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 shall determine such course of action to be appropriate, (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 obtain a refund thereof in appropriate administrative and judicial proceedings, or both; 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, 75 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 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 proviso in the preceding sentence is satisfied, (ii) such claim involves only Taxes for which the Lessee is liable to the taxing authority, (iii) 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), (iv) the participation of the Tax Indemnitee is not required, (v) no Tax return of the Tax Indemnitee is held open as a result of such contest, and (vi) 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. 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 (in a proceeding that involves taxes unrelated to the transactions contemplated by the Operative Documents) unless such Tax Indemnitee shall have received an opinion of such independent tax counsel as may be selected by the Tax Indemnitee and reasonably acceptable to the Lessee, furnished at the Lessee's sole expense, to the effect that there is a reasonable basis 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 76 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 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 77 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 78 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 Guarantee. 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 Secured Notes. 12.4 Opinion in Connection with Refunding of Senior Notes or Adjustments to Rent Percentages. In connection with any refunding or refinancing of the Secured Notes pursuant to Section 15 of this Agreement or any adjustment of the Basic Rent Percentages pursuant to Section 4 of the Lease to which the proviso set forth in Section 4.2 of the Lease applies, if the Lessee shall fail to provide the Owner Participant with an opinion of tax counsel selected by the Lessee but reasonably acceptable to the Owner Participant in form and substance to the effect that such refunding (or refinancing) or adjustment, as the case may be, more likely than not will not result in a greater risk of an unindemnified tax liability on the part of the Owner Participant, then the Lessee shall provide the Owner Participant with tax indemnity in form and substance reasonably satisfactory to the Owner Participant (including credit support). SECTION 13. TRANSFER OF OWNER PARTICIPANT'S INTEREST. 13.1 Restrictions on Transfer. Without the prior written consent of, so long as the Lease shall be in effect, the Lessee, and, so long as the Lien of the Indenture shall be in effect, the Indenture Trustee, the Owner Participant shall not, directly or indirectly, assign, convey or otherwise transfer (whether by consolidation, merger, sale of assets or otherwise) any of its right, title or interest in and to the Trust Estate, this Agreement, the Trust Agreement or any other Operative Document except in accordance with the terms and conditions of this Section 13; provided that in the case of any transfer that occurs while a Lease Event of Default has occurred and is continuing, (i) the conditions to transfer set forth in Sections 13.2 (d) and (e) shall not apply, (ii) the conditions to transfer set forth in 79 Section 13.2(a) shall be modified such that the only remaining requirement under such Section is that the transferee shall have a net worth at the time of transfer of at least $10,000,000 and (iii) the conditions to transfer in Section 13.2(f) shall be modified such that the Lessee shall not be entitled to require that the opinion referred to in said Section be in form and substance satisfactory to the Lessee. 13.2 Permitted Transfers. The Owner Participant may transfer all or part of its right, title and interest in and to the Trust Estate (whether or not the same shall then have been pledged or mortgaged under the Indenture, but subject to the Lien of the Indenture if then in effect) and in and to this Agreement and the other Operative Documents to any Person (a "Transferee") only in compliance with and upon satisfaction of the following conditions: (a) the Transferee (i) shall be, or shall be an Affiliate of, a financial institution, leasing company or other institutional investor having a tangible net worth at the time of at least $75,000,000 (or shall provide a guarantee in form and substance reasonably satisfactory to the Lessee and the Indenture Trustee of all its obligations under the Operative Documents to which it is a party by an entity having a tangible net worth at the time of at least $75,000,000), or (ii) shall be an Affiliate of the Owner Participant that either (x) has a net worth of at least $75,000,000 or (y) has its obligations under the Operative Documents guaranteed by the Owner Participant (or if at the time of transfer the Owner Participant's obligations are guaranteed pursuant to the Guaranty, by the Guarantor) pursuant to a guaranty in form and substance reasonably satisfactory to the Lessee and the Indenture Trustee; and in the case of either (i) or (ii) such Transferee shall not be a Competitor of the Lessee; (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; (c) the Transferee shall enter into an agreement substantially in the form of Exhibit B and shall have delivered to the Grantor Trustee and the Lessee an Officer's Certificate of the Transferee stating that the representations and warranties contained therein shall be true and correct on the date of transfer; 80 (d) the transferring Owner Participant shall have provided 10 Business Days prior written notice of such transfer to the Grantor Trustee, the Indenture Trustee and the Lessee, which notice shall specify (i) such information and be accompanied by evidence as shall be reasonably necessary to establish compliance with this Section 13 and Section 12.7 of the Trust Agreement and (ii) the name and address (for the purpose of giving notice as contemplated by the Operative Documents) of the Transferee; (e) the transferring Owner Participant shall pay or cause to be paid all reasonable fees, out-of-pocket expenses, disbursements and costs (including, without limitation, legal and other professional fees and expenses) incurred by the Grantor Trustee, the Loan Participants, the Indenture Trustee or the Lessee in connection with any transfer pursuant to this Section 13 (other than fees and expenses incurred in unsuccessfully challenging, through any action, suit or proceeding, the Owner Participant's right to make such transfer); (f) the transferring Owner Participant or the Transferee shall have delivered to the Grantor Trustee and the Lessee and, if the Lien of the Indenture shall then be in effect, the Indenture Trustee, an opinion of counsel in form and substance reasonably satisfactory to each of them, as to the due authorization, execution, delivery and enforceability of the agreement or agreements referred to in clause (c) of this Section 13.2, and as to the matters referred to in clause (b) of this Section 13.2; and (g) the Transferee shall be a "United States Person" as defined in the Code. 13.3 Request for Acknowledgment. In connection with any proposed transfer, assignment or assumption under Section 13.2, the Owner Participant may by notice to the Lessee, the Indenture Trustee and Chadbourne & Parke LLP, at the addresses set forth for such Persons in Schedule 1 hereto, at least 20 Business Days prior to the anticipated date of the proposed transfer or assignment, request that the Lessee and the Indenture Trustee acknowledge that any or all of the conditions precedent or requirements contained in Section 13.2 have been met, and such acknowledgment shall be promptly (and in any event with respect to each such party no more than 10 Business Days after such notice shall have been given) granted to the extent that such conditions or requirements are met. In connection therewith, the Owner Participant shall provide the Lessee and the Indenture Trustee with (a) an Officer's Certificate of the Owner Participant signed on behalf of the Owner Participant by a Responsible Officer of the Owner Participant to the effect that 81 all of the conditions precedent or requirements contained in Section 13.2 have been met and (b) all the information necessary, or with any information that the Lessee or the Indenture Trustee may reasonably request, in order for the Lessee and the Indenture Trustee to make such determination. If the Lessee or the Indenture Trustee fails to respond on or prior to the 30th day after receipt of any such notice, the Lessee or the Indenture Trustee, as the case may be, shall be deemed to have given its acknowledgment that such conditions precedent or requirements have been met. 13.4 Effect of Transfer. From and after any transfer effected in accordance with this Section 13, the Owner Participant making such transfer shall be released, to the extent of the obligations assumed by the Transferee, from its liability hereunder and under the other Operative Documents to which it is or is to be a party and under the Agency and Support Agreement in respect of obligations to be performed on or after the date of such transfer. 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, except as provided in the preceding sentence. In addition, except in the case of a transfer to an Affiliate of the Owner Participant in accordance with Section 13.2(a)(ii)(y), upon any transfer made in accordance with this Section 13, the Guaranty, if any, shall be released to the extent the obligation of the Owner Participant under the Operative Documents are assumed by the Transferee or, if applicable a new Guarantor. 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 10 days after the earlier of receipt by the Owner Participant of written notice thereof from the Lessee or the date the Owner Participant obtains Actual Knowledge of such failure; and provided further that the failure by the Owner Participant to pay fees and expenses in accordance with Section 13.2(e) shall not constitute a breach of this Agreement if such failure is cured within 60 days after the earlier of receipt by the Owner Participant of written notice thereof from the Lessee, the Grantor Trustee, the Loan Participants or the Indenture Trustee or the date the Owner Participant obtains Actual Knowledge of such failure. 82 SECTION 14. FINANCING FOR MODIFICATIONS. 14.1 Financing for Modifications. The Lessee shall give the Grantor Trustee, the Owner Participant and the Indenture Trustee any required notice of a Modification to the Production System pursuant to Section 11.6(b) of the Lease. Upon receipt of such notice, and so long as no Lease Default described in paragraphs (a), (b), (c) or (g) of the definition of Lease Event of Default in Section 15 of the Lease and no Lease Event of Default shall have occurred and be continuing, the Owner Participant shall cause the Lessor to finance the cost of the Lessor's Share of such Modification through the issuance of Additional Notes under the Indenture, on terms and conditions (including additional credit support to the extent required by Section 10.14 after giving effect to any adjustment in Stipulated Loss Value as a result of the issuance of Additional Notes) mutually acceptable to the Owner Participant and the Lessee; provided that any issuance and sale by the Grantor Trustee of Additional Notes shall be in accordance with and subject to the conditions set forth in Section 2.08 of the Indenture (including, without limitation, the condition that such Additional Notes may not rank senior (but may rank pari passu or junior) in any respect to other Secured Notes issued under the Indenture). On the closing date of any Supplemental Financing, the Basic Rent Percentages, Stipulated Loss Value Percentages, Termination Value Percentages, Early Buy-Out Percentages and Fixed Price Purchase Amount shall be adjusted in accordance with Section 4 of the Lease. No Additional Notes may be issued without the prior written consent of the Lessee. SECTION 15. REFUNDING OF SECURED NOTES. 15.1 Refunding of Secured Notes. Upon compliance with the terms and conditions of this Section 15, including, without limitation, the satisfaction of the conditions set forth in Section 15.2 and in Section 3.05 of the Indenture, the Lessee shall have the right, at its option and expense, on two occasions during the Lease Term to cause the Grantor Trustee to refund or refinance the Secured Notes and/or any Additional Notes then Outstanding (the "Refunded Secured Notes") through the issuance and sale in the public or private market of one or more additional series of Secured Notes (the "Refunding Secured Notes"), in an aggregate principal amount which shall be equal to the unpaid principal amount of the Refunded Secured Notes plus any accrued and unpaid interest on the Refunded Secured Notes not paid by Lessee as contemplated in clause (d) of this Section 15.1, the proceeds of such issuance and sale to be applied to prepay or redeem the principal amount of such Refunded Secured Notes and subject to the following conditions: 83 (a) the expenses of any such refunding or refinancing (including, without limitation, any premium payable with respect to the Secured Notes) shall be borne by the Lessee; (b) the Owner Participant will not suffer any unindemnified adverse tax consequences (as determined in accordance with and subject to Section 12.4) and Owner Participant will receive an opinion of its counsel and reasonably acceptable to the Lessee to such effect; provided, however, that, in the absence of a change in applicable tax law, Treasury Regulations or Internal Revenue Service published revenue ruling, revenue procedure or notice after the Closing Date, the Secured Notes are "qualified nonrecourse indebtedness" and any such refinancing taken together with each other refinancing, that does not (i) result in an increase in principal amount greater than 5.0% of the remaining principal amount of the Secured Notes or, as applicable any Additional Notes or (ii) increase in term or average life that exceeds the remaining term or average life, as applicable, of the original Secured Notes by more than six months, shall be treated as not causing a material adverse tax effect under Section 861 of the Code; (c) the appropriate parties will enter into a note purchase agreement providing for the issuance and sale by the Grantor Trustee or such other party as may be appropriate on the date specified in such agreement (for the purposes of this Section 15.1, the "Refunding Date") of Refunding Secured Notes the proceeds of which shall be used to repay all of the Outstanding Refunded Secured Notes on the Refunding Date; (d) if the Refunding Date is during the Basic Lease Term, the Lessee and the Grantor Trustee will amend the Lease such that if the Refunding Date is not a Basic Rent Payment Date, the Lessee shall on the Refunding Date prepay that portion of the next succeeding installment of Basic Rent to the extent necessary to pay the aggregate interest accrued on the Refunded Secured Notes not payable with the proceeds of the Refunding Secured Notes; (e) the Grantor Trustee will enter into an agreement to provide for the securing thereunder of the Refunding Secured Notes in like manner as the Refunded Secured Notes and/or will enter into such amendments and supplements to the Indenture as may be necessary to effect a refunding or refinancing under this Section 15.1, which agreements, amendments and/or supplements shall be satisfactory in form and substance to the Owner Participant; 84 (f) the identity of the Owner Participant shall not be disclosed in offering materials used in connection with such refunding or refinancing pursuant to a public offering; (g) unless otherwise agreed by the Owner Participant, the Lessee shall pay to the Grantor Trustee as Supplemental Rent an amount equal to the Premium, if any, payable in respect of the Refunded Secured Notes and all reasonable fees, costs, expenses of such refunding or refinancing, including, without limitation, the Owner Participant's out-of-pocket expenses and reasonable counsel fees and expenses; (h) the Lessee shall cause a legal opinion in form and substance reasonably satisfactory to the Owner Participant, the Grantor Trustee, the Indenture Trustee and the Pass Through Trustee to be addressed to the Owner Participant, the Grantor Trustee, the Indenture Trustee and the Pass Through Trustee with respect to federal or state securities laws and insofar as such laws relate to the refunding or refinancing; and (i) such additional documents, certificates, opinions as shall be reasonably requested by, and acceptable to, the Grantor Trustee and the Indenture Trustee, including, but not limited to, such documents, financing statements and opinions as are reasonably necessary to confirm that the refinancing of all Secured Notes of the series as to which the refinancing is occurring is being carried out. In connection with any such refunding or refinancing, the Basic Rent Percentages, Stipulated Loss Value Percentages, Termination Value Percentages and the Early Buy-Out Percentages and the amount of Credit Support shall be adjusted in accordance with Section 4 of the Lease. The Secured Notes may not be refunded or refinanced without the prior written consent of the Lessee. 15.2 Notice. The Lessee shall give the other parties to this Agreement at least 90 days' prior written notice of any desired refunding or refinancing pursuant to Section 15.1, which notice shall set forth to the extent practicable the proposed terms and conditions of such refunding or refinancing, including the desired date therefor. The Lessee, the Grantor Trustee, the Owner Participant and, as necessary, the Indenture Trustee and the Loan Participants, shall consult thereafter on the good faith negotiation of such terms and conditions to the end that, subject to the provisions of this Section 15, the final terms and conditions of such refunding shall be agreed among the parties thereto in due course thereafter. The Lessee will provide notice promptly to such Persons in the event that it determines not to 85 proceed with such proposed refunding or refinancing pursuant to Section 15.1. 15.3 Rights of Parties. Notwithstanding anything to the contrary contained in this Section 15, in no event shall the Owner Participant have any obligation to initiate or structure any refunding or refinancing of Secured Notes or to take, or to cause the Grantor Trustee to take, any action in connection therewith other than such as may be requested by the Lessee, the Owner Participant or the Indenture Trustee as provided in this Section 15. 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 of the Lease, the Lessee in lieu of exercising such right may elect to purchase the right, 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 (i) the applicable purchase price payable under Section 6.1 over (ii) the outstanding principal and accrued interest on the Secured 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 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 which shall at a minimum preserve Owner Participant's rights which are expressly stated to survive any purchase. 16.2 Notice of Election; Manner of Purchase Transfer After Purchase. (a) In order to exercise its right to purchase the Beneficial Interest pursuant to Section 16.1, the Lessee shall notify the Owner Participant irrevocably in writing no later than 90 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 Basic Rents due by the Lessee to or distributable to the Owner Participant on or prior to such date of purchase (but excluding any Basic Rent payable in advance on such date of purchase) and all Supplemental Rent due by the Lessee to or distributable to the Owner Participant to and including such date of purchase (without giving effect to any applicable grace periods), the Owner Participant shall transfer the Beneficial Interest free and 86 clear of all Liens to the Lessee pursuant to an instrument of conveyance in form and substance reasonably satisfactory to the Lessee. (c) Each of the Participants, the Grantor Trustee and the Indenture Trustee, at the cost and 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 reasonably may 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 the Beneficial Interest pursuant to Section 16.1 (unless the Lessee shall assume the obligations of the Grantor Trustee pursuant to the next sentence), on the date of purchase the Lessee shall have provided to the Indenture Trustee an opinion of counsel for the Lessee, 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, 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 Grantor Trustee under the Secured 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. SECTION 17. MISCELLANEOUS. 17.1 Survival.

The division of this Agreement into Sections, subsections and paragraphs, the provision of a table of contents and the insertion of headings are for convenience of reference only and shall not affect the construction or interpretation hereof. 17.8 Severability of Provision. Any provision of this Agreement which may be determined by competent authority to be invalid or unenforceable in such jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable any remaining terms and provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties shall negotiate in good faith to replace such provision with an appropriate, legal provision. To the extent permitted by applicable law, the parties hereto hereby waive any provision thereof that renders any term or provision hereof invalid or unenforceable in any respect. 17.9 Entire Agreement.
