Notwithstanding the foregoing, any Indemnitee's failure to notify Lessee as provided in this ss. 9.1.4, or in ss. 9.1.5, shall not release Lessee fRom any of its obligations to indemnify such Indemnitee hereunder, except to the extent that such failure results in an additional Expense to Lessee (in which event Lessee shall not be responsible for such additional expense) or materially impairs Lessee's ability to contest such claim. 9.1.5 NOTICE OF PROCEEDINGS; DEFENSE OF CLAIMS; LIMITATIONS (a) If any action, suit, or proceeding for which Lessee is responsible under this ss. 9.1 is brought against any Indemnitee, such Indemnitee shall notify Lessee of the commencement thereof, and Lessee may, at its expense, participate in and, to the extent that it so desires (subject to the provisions of the following paragraph), assume and control its defense and, subject to ss. 9.1.5(c), settle or compromise it. Unless OwneR Participant agrees in writing otherwise, no settlement of any claim hereunder may require Owner Participant to agree to any remedy apart from the payment of money damages (for which such payment of money damages Lessee will in any event indemnify the Indemnitees). (b) Lessee or its insurer(s) shall have the right, at its or their expense, to investigate or, if Lessee or its insurer(s) agree not to dispute liability to the Indemnitee giving notice of such action, suit, or proceeding under this ss. 9.1.5 for indemnification hereunder or under anY insurance policies pursuant to which coverage is sought, control the defense of, any action, suit, or proceeding, relating to any Expense for which indemnification is sought pursuant to this ss. 9.1, and each Indemnitee shall cooperate with Lessee or its insurer(s) with respect thereto; PROVIDED, thaT Lessee shall not be entitled to control the defense of any such action, suit, or proceeding, or to settle or compromise any such Expense, (i) while any Special Default or Lease Event of Default under ss. 14.1 of the Lease exists, or (ii) if such action, suit, or proceeding will involve a material risk of thE sale, forfeiture, or loss of, or the creation of any Lien (other than a Permitted Lien) on the Aircraft, the Trust Estate, or any part thereof, unless Lessee shall have posted a bond or other security or collateral satisfactory to Owner Participant and Mortgagee in respect to such risk, or (iii) if such action, suit, or proceeding could in the good faith opinion of such Indemnitee entail any risk of criminal liability or material civil liability or present a conflict of interest making separate representation necessary. In connection with any such Lessee-controlled action, suit, or proceeding, such Indemnitee shall have the right to participate therein, at its sole cost and expense, with counsel reasonably satisfactory to Lessee, provided that such Indemnitee's participation does not, in the reasonable opinion of the independent counsel appointed by Lessee or its insurers to conduct such proceedings, interfere with the defense of such case. (c) In no event shall any Indemnitee enter into a settlement or other compromise with respect to any Expense without Lessee's prior written consent (which shall not be unreasonably withheld or delayed), unless such Indemnitee waives its right to be indemnified with respect to such Expense under this ss. 9.1. (d) To the extent that any Expense indemnified by Lessee hereunder may be covered by insurance maintained by Lessee, at Lessee's expense, each Indemnitee agrees to cooperate with the insurers in the exercise of their rights to investigate, defend, or compromise that Expense as may be required to retain the benefits of the insurance for that Expense. (e) If an Indemnitee is not a party to this Agreement, Lessee may require that Indemnitee to agree in writing to the terms of this ss. 9 and ss. 15.8 before making any payment to such Indemnitee under this ss. 9. (f) Nothing herein shall be deemed to be an assumption by Lessee of obligations of Owner Trustee with respect to, or a guarantee by Lessee of, any amounts payable by Owner Trustee upon Equipment Notes or a guarantee of any residual value of the Aircraft. (g) Nothing in this ss. 9.1.5 shall require an Indemnitee to contest any Expense or to assume responsibility for or control of any judicial proceeding with respect thereto. 9.1.6 INFORMATION Lessee will provide the relevant Indemnitee with such information not within the control of such Indemnitee (but in Lessee's control or reasonably available to Lessee) which such Indemnitee reasonably requests, and will otherwise cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its obligations under ss. 9.1.5 and to control or participate in any proceeding to the extent permitted by ss. 9.1.5.

Each Indemnitee will give such further assurances or agreements and cooperate with Lessee to permit Lessee to pursue any such claims, to the extent reasonably requested by Lessee and at Lessee's expense. 9.1.8 REFUNDS If an Indemnitee receives any refund, in whole or in part, with respect to any Expense paid by or on behalf of Lessee hereunder, that Indemnitee will promptly pay the amount refunded (but not an amount in excess of the amount Lessee or any of its insurers has paid in respect of such Expense) over to Lessee unless a Lease Event of Default exists, in which case such amount shall be paid over to Owner Trustee (or, if the Mortgage has not been discharged, to Mortgagee) to hold as security for Lessee's obligations under the Lessee Operative Agreements or, if requested by Lessee, applied to satisfy those obligations.

Notwithstanding the foregoing, Lessee at its sole option shall have the right to pay directly any and all Transaction Expenses payable to Lessee Advisor or Lessee's counsel or (if such payment does not result in adverse tax consequences to Owner Participant) to any other Person. If Owner Participant fails to pay any Transaction Expense that it is obligated to pay hereunder, Lessee shall pay such Transaction Expense. Any such payment by Lessee shall not affect Owner Participant's obligations or Lessee's rights against Owner Participant for its failure to make any such payment. 9.2.2 PAYMENT OF OTHER EXPENSES Lessee shall pay (a) the ongoing fees and expenses of Owner Trustee and Mortgagee, and (b) all reasonable out-of-pocket costs and expenses (including the reasonable fees and disbursements of counsel) incurred by any Participant attributable to (1) any transfer of title to the Aircraft or any Engine contemplated by ss. 4.5 of the Lease, or (2) any waiver, amendment, or modification of any Operative Agreement to the extent requested by Lessee. 9.2.3 INDEMNIFICATION INTEREST Lessee will pay to each Indemnitee upon demand, to the extent permitted by applicable Law, interest at the Past Due Rate on any amount of indemnity not paid when due pursuant to this ss. 9 until the same shall be paid. 9.3 GENERAL TAX INDEMNITY 9.3.1 GENERAL Except as provided in ss. 9.3.2, Lessee agrees that each payment of Rent paid by Lessee pursuant to the Lease, and any other payment or indemnitY paid by Lessee to a Tax Indemnitee under any Operative Agreement, shall be free of all withholdings or deductions with respect to Taxes of any nature, and if Lessee is required by applicable law to make any such withholding or deduction for any such payment, (a) Lessee shall make all such withholdings or deductions, (b) the amount payable by Lessee shall be increased so that, after making all required withholdings or deductions, such Tax Indemnitee receives the same amount that it would have received had no such withholdings or deductions been made, and (c) Lessee shall pay the full amount withheld or deducted to the relevant Taxing Authority in accordance with applicable law. Lessee further agrees that, if it is required to withhold from any payment of Basic Rent, Stipulated Loss Value (and amounts determined by reference thereto), and amounts payable upon exercise of Lessee's purchase option pursuant to ss. 17.3 of the Lease, any Tax imposed upon Owner Participant or Owner Trustee (including any withholding Tax based on income or receipts of Owner Participant or Owner Trustee), and such Tax is excluded from indemnification pursuant to ss. 9.3.2, Lessee shall pay such additional amount (if any) required so that thE total amount paid by Lessee (after making all required withholdings) is equal to (assuming timely payment of the Equipment Notes before the relevant Payment Date) the aggregate principal amount of scheduled installments due on the Equipment Notes outstanding on the relevant Payment Date, together with accrued and unpaid interest, due on the Equipment Notes; and Owner Participant or Owner Trustee (as applicable) shall reimburse Lessee for any such additional amounts within two Business Days after demand therefor.

If a tax benefit is later disallowed or denied, the disallowance or denial shall be treated as a Tax indemnifiable under ss. 9.3.1 without regard to the provisions of ss. 9.3.2 (other than ss. 9.3.2(f)). Each such Tax Indemnitee shall in good faitH use reasonable efforts in filing its tax returns and in dealing with Taxing Authorities to seek and claim any such tax benefit. 9.3.4 CONTEST (a) If a written claim is made against a Tax Indemnitee for Taxes that Lessee could be liable to pay or indemnify for hereunder, or if a Tax Indemnitee determines that a Tax is due and that Lessee could have an indemnity obligation for that Tax hereunder, such Tax Indemnitee shall promptly notify Lessee in writing of such claim (PROVIDED, that failure so to notify Lessee shall not relieve Lessee of its indemnity obligations hereunder unless the failure to notify effectively forecloses Lessee's rights to require a contest of such claim), and shall take no action with respect to such claim without Lessee's prior written consent for 30 days following Lessee's receipt of such notice; PROVIDED, that, if applicable Law requires such Tax Indemnitee to take action before the end of such 30-day period, such Tax Indemnitee shall, in such notice to Lessee, so inform Lessee, and such Tax Indemnitee shall take no action for as long as it is legally able to avoid taking action (and a Tax Indemnitee shall be entitled to pay the Tax claimed and sue for a refund before the end of such 30-day period if (1)(aa) the failure to pay the Tax would result in substantial penalties (unless immediately reimbursed by Lessee) and the act of paying the Tax would not materially prejudice the right to contest, or (bb) the failure to pay would result in criminal penalties, and (2) such Tax Indemnitee shall take any action so required in connection with so paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In addition, such Tax Indemnitee shall (provided that Lessee shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim) furnish Lessee with copies of any requests for information from any Taxing Authority relating to such Taxes with respect to which Lessee may be required to indemnify hereunder. If requested by Lessee in writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at Lessee's expense (including all reasonable costs, expenses, and reasonable attorneys' and accountants' fees and disbursements), in good faith contest (or, if permitted by applicable law, allow Lessee to contest) through appropriate administrative and judicial proceedings the validity, applicability, or amount of such Taxes by (x) resisting payment thereof, (y) not paying the Taxes except under protest if protest is necessary and proper, or (z) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative or judicial proceeding. If requested to do so by Lessee, the Tax Indemnitee shall appeal any adverse administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue any appeals to the United States Supreme Court. If and to the extent that the Tax Indemnitee is able to separate the contested issue(s) from other issues arising in the same administrative or judicial proceeding that are unrelated to the Transactions without (in such Tax Indemnitee's good faith judgment) adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Lessee to control the conduct of any such proceeding and shall provide to Lessee (at Lessee's cost and expense) with such information or data in such Tax Indemnitee's control or possession and reasonably necessary to conduct such contest (other than such Tax Indemnitee's federal income Tax returns) in which case Lessee shall keep such Tax Indemnitee reasonably informed concerning the progress of such contest. If the contest is being controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Lessee in good faith regarding the manner of contesting such claim and shall keep Lessee reasonably informed regarding the progress of such contest. A Tax Indemnitee shall not fail to take any action expressly required by this ss. 9.3.4 (including anY action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without Lessee's prior written consent (except as contemplated by ss. 9.3.4(b) or (c)). (b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Lessee to pursue any contest) unless (1) Lessee agrees to pay to such Tax Indemnitee on demand and on an after-tax basis all reasonable costs and expenses that such Tax Indemnitee incurs in connection with contesting such Taxes, including all reasonable out-of-pocket costs and expenses and reasonable attorneys' and accountants' fees and disbursements, (2) if such contest involves the payment of the claim, Lessee advances the amount thereof (to the extent indemnified hereunder) plus interest, penalties, and additions to tax with respect thereto that are required to be paid before commencing the contest on an interest-free net after-Tax basis to such Tax Indemnitee, (3) such Tax Indemnitee does not reasonably determine that the action to be taken will result in any material risk of forfeiture, sale, or loss of the Aircraft (unless Lessee makes provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) (PROVIDED, that such Tax Indemnitee shall notify Lessee in writing promptly after it becomes aware of any such risk), (4) no Lease Event of Default exists, unless Lessee has provided security for its obligations hereunder by advancing to such Tax Indemnitee, before proceeding or continuing with such contest, the amount of the Tax being contested, plus any interest and penalties and an amount estimated in good faith by such Tax Indemnitee for expenses, (5) before commencing any judicial action controlled by Lessee, Lessee acknowledges its liability for such claim hereunder in writing, PROVIDED, that Lessee shall not be bound by its acknowledgment if the Final Determination articulates conclusions of law and fact that demonstrate that Lessee has no liability for the contested amounts hereunder, (6) such Tax Indemnitee shall have received at Lessee's sole expense, an opinion independent tax counsel, such counsel to be selected by Lessee and reasonably satisfactory to such Tax Indemnitee ("Tax Counsel"), to the effect that a reasonable basis, within the meaning of ABA Formal Opinion No. 85-352, exists for contesting such claim, (7) the amount of payments or indemnification that would be required as a result of such adjustment, when aggregated with further potential payments or adjustments where the subject matter of the proposed adjustment is of a continuing nature, as to the Aircraft and all other aircraft operated by Lessee, shall be at least $10,000, and (8) the issue shall not be substantially identical as an issue previously contested hereunder and decided adversely, unless such Tax Indemnitee shall have received, at Lessee's sole expense, a written opinion, in form and substance reasonably satisfactory to such Tax Indemnitee, of Tax Counsel to the effect that the applicable circumstances or law have changed and in light thereof, there is reasonable basis under ABA Formal Opinion No. 85-352 that the tax treatment of the item which is the subject of the claim will be upheld in litigation if the claimed tax treatment is challenged by a Taxing Authority. Notwithstanding the foregoing, if any Tax Indemnitee releases, waives, compromises, or settles any claim that may be indemnifiable by Lessee pursuant to this ss. 9.3 and which such Tax Indemnitee is otherwise obligated to contest under this ss. 9.3.4 without Lessee's written permissiOn, Lessee's obligation to indemnify such Tax Indemnitee with respect to such claim (and all directly-related claims, and claims based on the outcome of such claim) shall terminate, subject to ss. 9.3.4(c), and subject to ss. 9.3.4(c), such Tax Indemnitee shall repay to Lessee any amount previously paid or advanCed to such Tax Indemnitee with respect to such claim, plus interest at the rate that would have been payable by the relevant Taxing Authority on a refund of such Tax. (c) Notwithstanding anything in this ss. 9.3, a Tax Indemnitee will not be required to contest the imposition of any Tax, and shall bE permitted to settle or compromise any claim without Lessee's consent, if such Tax Indemnitee (1) waives its right to indemnity under this ss. 9.3 witH respect to such Tax (and any directly-related claim, and any claim the outcome of which is determined based upon the outcome of such claim), (2) pays to Lessee any amount previously paid or advanced by Lessee pursuant to this ss. 9.3 with respect to such Tax, plus interest at the rate that would have beeN payable by the relevant Taxing Authority on a refund of such Tax, and (3) agrees to discuss with Lessee the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax PROVIDED, that if Lessee has agreed in writing to settle a claim for a stated amount and the relevant Tax Indemnitee settles the claim on more favorable terms, such Tax Indemnitee shall not be required to waive the indemnity for such claim to the extent of the amount agreed to by Lessee. 9.3.5 REFUND If any Tax Indemnitee receives a refund of, or becomes entitled to a credit against other liability for, all or any part of any Taxes paid, reimbursed, or advanced by Lessee, such Tax Indemnitee shall pay to Lessee within 30 days of such receipt an amount equal to the lesser of (a) the amount of such refund or credit plus any net tax benefit (taking into account any Taxes incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee made pursuant to this sentence (including this clause (a)), and (b) such tax payment, reimbursement, or advance by Lessee to such Tax Indemnitee theretofore made pursuant to this ss. 9.3 (and the excess, if any, of the amount described in clause (a) over the amount described in clause (b) shall be carried forward and applied to reduce PRO TANTO any subsequent obligation of Lessee to make payments to such Tax Indemnitee pursuant to this ss. 9.3). If, in addition to such refund or credit, sucH Tax Indemnitee receives (or is credited with) an amount representing interest on the amount of such refund or credit, such Tax Indemnitee shall pay to Lessee within 30 days after receiving or realizing such credit the portion of such interest fairly attributable to Taxes paid, reimbursed, or advanced by Lessee before the receipt of such refund or realization of such credit. Notwithstanding the foregoing, a Tax Indemnitee shall not be obligated to make any payment to Lessee pursuant to this ss. 9.3.5 if a Special Default or a Lease Event of Default has occurred and is continuing. If it is later determined thaT such Tax Indemnitee was not entitled to such refund or credit, the portion of the refund or credit repaid, recaptured or disallowed (and any interest and tax savings paid by such Tax Indemnitee to Lessee with respect thereto) shall be treated as Taxes for which Lessee must indemnify such Tax Indemnitee pursuant to this ss. 9.3 without regard to ss. 9.3.2 hereof other than ss. 9.3.2(f). 9.3.6 TAX FILING Lessee shall timely file any report, return, or statement that is required to be filed with respect to any Tax which is subject to indemnification under this ss. 9.3 (except for any such report, return, or statement which a Tax Indemnitee has timely notified Lessee in writing that sucH Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to file, in its own name); PROVIDED, that the relevant Tax Indemnitee shall furnish Lessee with any information in such Tax Indemnitee's possession or control that is reasonably necessary to file any such return, report, or statement and that Lessee reasonably requests in writing (but the Tax Indemnitee shall not be required to furnish copies of its actual tax returns, although it may be required to furnish relevant information contained therein). Lessee shall either file such report, return, or statement and send a copy to such Tax Indemnitee (and to Owner Trustee, if the Tax Indemnitee is not Owner Trustee), or, if Lessee is not permitted to file such report, return, or statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such report, return, or statement to such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee within a reasonable time before the time such report, return, or statement is to be filed. 9.3.7 FORMS Each Tax Indemnitee agrees to furnish from time to time to Lessee, Mortgagee, or such other Person as Lessee or Mortgagee shall designate, at Lessee's or Mortgagee's request, such duly-executed and properly-completed forms as may be necessary or appropriate in order to claim any reduction of or exemption from any withholding or other Tax imposed by any Taxing Authority, if (a) such reduction or exemption is available to such Tax Indemnitee, and (b) Lessee has provided such Tax Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee. 9.3.8 NON-PARTIES If a Tax Indemnitee is not a party to this Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Lessee, to the terms of this ss. 9.3 and ss. 15.8 before making any payment to such Tax Indemnitee under this ss. 9.3. 9.3.9 FOREIGN TAX ON LOAN PAYMENTS If an Owner Participant is incorporated or organized, or maintains a place of business in a country other than the United States or in a territory, possession, or commonwealth of the United States (within the meaning of the tax law of that foreign jurisdiction), and if as a result thereof any foreign Taxes (including withholding Taxes) are imposed on the Pass-Through Trustees, Pass-Through Trusts, or Note Holders, then such Owner Participant shall reimburse Lessee for any payments that Lessee is required to make to or on behalf of any Pass-Through Trustee, Pass-Through Trust, or Note Holder under this ss. 9.3 as a result of the imposition of such Taxes.
