The C Check Option shall be exercised, if at all, by Lessee delivering an irrevocable written notice (a "C Check Notice") to Lessor not later than one hundred eighty (180) days prior to the New Expiration Date (as defined below) proposed by Lessee which notice shall state whether Lessee desires to extend the Term and the proposed date of performance and completion of the aforementioned C Check. Upon the receipt by Lessor of the C Check Notice, (xx) Lessee shall be obliged to lease the Aircraft from Lessor until the date (the "New Expiration Date") of completion of the aforementioned C Check in accordance with the terms and conditions of this Agreement; and (yy) the definition of "Expiration Date" shall be deemed to have been amended so as to refer to the New Expiration Date and the Aircraft shall be redelivered to Lessor on that date (or, as may be applicable, any other date contemplated by such definition) in accordance with the terms and conditions of this Agreement. I. PAYMENTS A. Aircraft Deposit. In order to faithfully secure its obligations hereunder, Lessee shall pay to Lessor an Aircraft Deposit in the amount set forth in paragraph 1 of the Letter Agreement and in accordance with the schedule set forth in that paragraph. The Aircraft Deposit shall be nonrefundable during the Term, and shall be held by Lessor as security for (i) the timely and faithful performance by Lessee of all of Lessee's obligations under this Lease (including, but not limited to, any prepetition or postpetition obligations of Lessee in connection with any proceeding or other action involving Lessee under any bankruptcy, insolvency or reorganization Law of any jurisdiction), (ii) all payments of Rent and Maintenance Reserves due and owing from time to time, (iii) any and all damages incurred by Lessor which may arise as a result of the breach or rejection of the Lease, whether or not in connection with a motion to lift stay or a motion to assume or reject the Lease, including, without limitation, overdue interest, costs of preservation or protection of the Aircraft and costs of repossession and (iv) all attorney's fees incurred by Lessor in connection with any relating to any of the above, whether or not litigation is instituted and whether incurred before or after the filing by Lessee of a petition under Chapter 7 or Chapter 11 of the Bankruptcy Code. Unless this Lease Agreement shall have been earlier terminated pursuant to Section 13.2, and provided that no Default shall have occurred and be continuing, the Aircraft Deposit shall be returned by Lessor to Lessee on the Expiration Date. A. Rental Periods. The Term will be divided into Rental Periods. The first Rental Period will commence on the Delivery Date and end on the last day of the calendar month during which the Delivery Date occurs, with the Rent for such first Rental Period and the last Rental Period to be prorated on a daily basis to reflect the actual number of days in such first and last Rental Periods. The second and each subsequent Rental Period will commence on the first day of each month next following the last day of the previous Rental Period. Each Rental Period will end on the last day of each month except that if a Rental Period would otherwise overrun the Expiration Date, it will end on the Expiration Date. A. Rent. Lessee will pay to Lessor or its order on each Rent Date, Rent, in advance, in immediately available funds in the amount set forth in paragraph 2 of Letter Agreement. Payment must be initiated adequately in advance of the Rent Date to ensure that Lessor receives funds on the Rent Date. If a Rental Period begins on a non-Business Day, the Rent payable in respect of that Rental Period shall be paid on the Business Day immediately preceding the date on which such Rental Period commences. B. Maintenance Reserves. 1. Amount. Lessee will also pay to Lessor Maintenance Reserves in relation to each Rental Period (including without limitation the last Rental Period of the Term) on the 10th day following the end of the preceding Rental Period as follows: a) in respect of the Airframe, the amount set forth in paragraph 3 (i) of Letter Agreement in respect of each Flight Hour operated by the Aircraft during that Rental Period ("Airframe Maintenance Reserves"); and a) in respect of each Engine, the amount set forth in paragraph 3 (ii) of Letter Agreement in respect of each Flight Hour operated by that Engine during that Rental Period ("Engine Refurbishment Maintenance Reserves"); a) in respect of the APU, the amount set forth in paragraph 3 (iii) of Letter Agreement in respect of each Flight Hour operated by the APU during that Rental Period ("APU Refurbishment Maintenance Reserves"); and a) in respect of the Landing Gear, the amount set forth in paragraph 3 (iv) of Letter Agreement in respect of each Flight Hour operated by the Landing Gear during that Rental Period ("Landing Gear Maintenance Reserves"). 1. Adjustment. The rate of Maintenance Reserves may be adjusted upwards annually by Lessor at the rate of up to 3 percent per annum commencing on the first anniversary of the Delivery Date. In addition, but not limiting the foregoing, Lessee acknowledges that the rates of Maintenance Reserves currently provided for in this Agreement are based upon the assumptions that (i) the Agreed Maintenance Program for the Aircraft during the Term will be the same as that in effect on the Delivery Date and (ii) the ratio of Flight Hours to Cycles is 1.2:1. In the event that either such assumption proves to be incorrect at any time during the Term, Lessor and Lessee agree that Lessor shall have the right, upon written notice to Lessee, to adjust the rate of Maintenance Reserves so as to reasonably account for the incorrectness of such assumptions. In the event that the Agreed Maintenance Program changes during the Term (any such change to be in accordance with the relevant terms and conditions of this Agreement), Lessor shall make the aforementioned adjustment in the manner which Lessor determines, in its reasonable discretion, is necessary to maintain the rates of Maintenance Reserves at levels which accurately reflect the costs associated with obtaining the affected maintenance services referred to in Section 7.2 at prevailing industry rates. Each such notice shall specify the revised rate of Maintenance Reserves and the effective date of such revision. Lessee agrees to advise Lessor, in writing, of any circumstances or events which would result in the foregoing assumptions becoming incorrect at any time during the Term. 1. General. Maintenance Reserves will not be held in a blocked or other escrow account, nor shall the amount of any Maintenance Reserves in excess of the amounts payable toward accomplishment of the various maintenance tasks in accordance with Section 7.2 hereof be refunded to Lessee. A. Payments. All payments by Lessee to Lessor under this Agreement will be made on the due date in Dollars and in immediately available funds settled through the New York Clearing House System by wire transfer to Mercantile Bank of Dubuque, (Acct. No. 28100164518), ABA No. 073900111. Such account shall be established in such a fashion as to ensure that Lessor's bank will be paid automatically from such account any amounts owing to the Bank in respect of the Aircraft. A. Gross-up. 1. All payments by Lessee under or in connection with this Agreement will be made without set-off or counterclaim, free and clear of and without deduction for or on account of all Taxes (other than Lessor Taxes); 1. All Taxes (other than Lessor Taxes) in respect of payments under this Agreement shall be for the account of and will be paid by Lessee for its own account prior to the date on which penalties apply; and 1. If Lessee is compelled by law to make payment subject to any Tax (other than Lessor Taxes) and Lessor does not actually receive for its own benefit on the due date a net amount equal to the full amount provided for under this Agreement, Lessee will pay all necessary additional amounts to ensure receipt by Lessor of the full amount so provided for. A. Taxation. Lessee will on demand pay and indemnify Lessor against all Taxes (other than Lessor Taxes) levied or imposed against or upon Lessor or Lessee and relating to or attributable to Lessee, this Agreement or the Aircraft directly or indirectly in connection with the importation, exportation, registration, ownership, leasing, sub leasing, delivery, possession, use, operation, repair, maintenance, overhaul, transportation, landing, storage, presence or redelivery of the Aircraft or any part thereof or any rent, receipts, insurance proceeds, income or other amounts arising therefrom. A. Value Added Tax. 1. For the purposes of this subsection: a) "VAT" means value added tax and any sales or turnover tax or imposition of a like nature; a) "supply" includes anything on which VAT is chargeable; 1. Lessee will pay to Lessor the amount of any VAT chargeable in respect of any supply of goods or services for VAT purposes under this Agreement; and 1. Each amount stated as payable by Lessee under this Agreement is exclusive of VAT (if any) and is accordingly to be construed as a reference to that amount plus any VAT in respect of it. A. Information. If Lessee is required by any applicable law, or by any third party, to deliver any report or return in connection with any Taxes, Lessee will complete the same in a manner satisfactory to Lessor and in particular will state therein that Lessee is exclusively responsible for the use and operation of the Aircraft and for any Taxes arising therefrom, and Lessee will, on request supply a copy of the report or return to Lessor. A. Taxation of Indemnity Payments. 1. If and to the extent that any sums payable to Lessor by Lessee under this Agreement by way of indemnity are insufficient, by reason of any Taxes payable in respect of those sums, for Lessor to discharge the corresponding liability to the relevant party (including any taxation authority), or to reimburse Lessor for the cost incurred by it to a third party (including any taxation authority) Lessee will pay to Lessor such sum as will after the tax liability has been fully satisfied leave Lessor with the same amount as it would have been entitled to receive in the absence of that liability together with interest on the amount of the deficit at the rate of interest stated in Section 5.11 in respect of the period commencing on the date on which the payment of taxation is finally due until payment by Lessee (both before and after judgment); and 1. If and to the extent that any sums constituting (directly or indirectly) an indemnity to Lessor but paid by Lessee to any person other than Lessor are treated as taxable in the hands of Lessor, Lessee will pay to Lessor such sum as will after the tax liability has been fully satisfied indemnify Lessor to the same extent as it would have been indemnified in the absence of such liability together with interest on the amount payable by Lessee under this subsection at the rate of interest stated in Section 5.11 in respect of the period commencing on the date on which the payment of taxation is finally due until payment by Lessee (both before and after judgment) provided however that Lessee will not be liable for any Lessor Taxes incurred as a result of the payment of the Agreed Value pursuant to Section 11. A. Default Interest. If Lessee fails to pay any amount payable under this Agreement on the due date, Lessee will pay on demand from time to time to Lessor interest (both before and after judgment) on that amount, from the due date to the date of payment in full by Lessee to Lessor, at the rate calculated by Lessor to be the Prime Rate plus five percent (5%) per annum. All such interest will be compounded monthly and calculated on the basis of the actual number of days elapsed and a 360 day year. A. Contest. If Lessee disputes the payment of any Taxes payable by Lessor for which Lessee is responsible under this Agreement, Lessor will consider with Lessee the taking of such action as Lessee may reasonably request at Lessee's expense to contest that payment but will not be obliged to take any such action: 1. Which Lessor considers in its sole discretion may prejudice it; or 1. Which Lessor considers does not have a reasonable prospect of success; or 1. For which Lessee has not made adequate provision to the satisfaction of Lessor in respect of the expense concerned. A. Absolute and Conditional Obligations of Lessee. Lessee's obligations under this Agreement are absolute and unconditional irrespective of any contingency whatsoever including (but not limited to): 1. Any right of set-off, counterclaim, recoupment, defence or other right which either party to this Agreement may have against the other; 1. Any unavailability of the Aircraft for any reason, including, but not limited to, a requisition of the Aircraft or any prohibition or interruption of or interference with or other restriction against Lessee's use, operation or possession of the Aircraft; 1. Any lack or invalidity of title or any other defect in title, airworthiness, merchantability, fitness for any purpose, condition, design, or operation of any kind or nature of the Aircraft for any particular use or trade, or for registration or documentation under the laws of any relevant jurisdiction, or any Event of Loss in respect of or any damage to the Aircraft; 1. Any insolvency, bankruptcy, reorganization, arrangement, readjustment of debt, dissolution, liquidation or similar proceedings by or against Lessor or Lessee; 1. Any invalidity or unenforceability or lack of due authorization of, or other defect in, this Agreement; and 1. Any other cause which but for this provision would or might otherwise have the effect of terminating or in any way affecting any obligation of Lessee under this Agreement. A. Security. 1. It is intended by Lessor and Lessee that the Maintenance Reserves payable by Lessee to Lessor pursuant to Section 5.4 are amounts paid by Lessee to Lessor in consideration for the use of the Aircraft by Lessee and the satisfaction of Lessee's obligations under this Agreement and that, except as otherwise provided in Section 7.2, once paid, those monies irrevocably and unconditionally shall be the property of Lessor. Notwithstanding that stated intent, if and to the extent that those monies or any thereof, under any applicable law or otherwise, are determined to be security deposits or otherwise the property of Lessee or if it is so determined those monies are a debt owed to Lessee or that Lessee, other than as set forth in Section 7.2, shall have any interest in those monies (the "Maintenance Reserve Account"), the parties agree that subsections (c), (d) and (e) below shall apply; 1. It is further intended by Lessor and Lessee that Aircraft Deposit payable by Lessee to Lessor pursuant to Section 5.1 and, if applicable, the Insurance Security Deposit contemplated by the first paragraph of Schedule 4 (collectively, the "Deposits") are security deposits to faithfully secure the satisfaction by Lessee of its obligations under the Agreement. 1. To the fullest extent permitted by law and by way of continuing security, Lessee grants to Lessor a security interest in the Maintenance Reserve Account and the Deposits and all rights of Lessee to payment thereof, the debt represented thereby and/or any and all interest of Lessee therein to Lessor by way of first priority security interest as security for Lessee's obligations and liabilities under this Agreement and the Other Agreements (the "Secured Liabilities"). Except as expressly permitted under Sections 7.2 or otherwise under this Agreement, Lessee will not be entitled to payment of the Maintenance Reserve Account. Except as expressly permitted under Section 5.1 and Schedule 4 of this Agreement, Lessee will not be entitled to payment of the Deposits. Lessee will not assign, transfer or otherwise dispose of all or part of its rights in the Maintenance Reserve Account or the Deposits and Lessee agrees that it will enter into any additional documents and instruments necessary or reasonably requested by Lessor to evidence, create or perfect Lessor's rights in the Reserve Account and the Deposits. 1. If Lessee fails to comply with any provision of this Agreement or any Event of Default has occurred and is continuing Lessor may immediately or at any time thereafter, without prior notice to Lessee: a) Set-off all or any part of the Secure Liabilities against the contribution and/or refund liabilities of Lessor in respect of the Maintenance Reserve Account and/or the Deposits; or a) Apply or appropriate the Maintenance Reserve Account and/or the Deposits in or towards the payment or discharge of the Secured Liabilities in such order as Lessor sees fit; and 1. If Lessor has exercised the set-off described in sub-clause (d) above, Lessee shall, following a demand in writing from Lessor, promptly restore the Maintenance Reserve Account and/or the Deposits, as applicable, to the level at which they stood immediately prior to such set-off. I. MANUFACTURER'S WARRANTIES A. Assignment. Notwithstanding this Agreement, Lessor will remain entitled to the benefit of each warranty, express or implied, with respect to the Aircraft, any Engine or Part so far as concerns any manufacturer, vendor, subcontractor or supplier or any seller from whom Lessor acquired the Aircraft. Except to the extent Lessor otherwise directs, Lessor hereby authorizes Lessee to pursue any claim against any manufacturer, vendor or supplier (but not any seller of the Aircraft) in relation to defects affecting the Aircraft, any Engine or Part and Lessee agrees diligently to pursue any such claim which arises at its own cost. Lessee will notify Lessor promptly upon becoming aware of any such claim. A. Proceeds. Except to the extent Lessor otherwise agrees in a particular case, all proceeds of any such claim will be paid directly to Lessor, except, but if and to the extent that such claim relates: 1. To defects affecting the Aircraft which Lessee has rectified; or 2. To compensation for loss of use of the Aircraft, an Engine or any Part during the Term; and provided no Default has occurred and is continuing, the proceeds will be paid to Lessee by Lessor but only on receipt of evidence satisfactory to Lessor that Lessee has rectified the relevant defect. A. Parts. Except to the extent Lessor otherwise agrees in a particular case, Lessee will procure all engines, components, furnishings or equipment provided by the manufacturer, vendor, subcontractor or supplier in replacement of a defective Engine or Part pursuant to the terms of any warranty, all of which will be installed promptly by Lessee such that title thereto vests in Lessor free of Security Interests. On installation those items will be deemed to be an Engine or Part as applicable. A. Agreement. To the extent any warranties relating to the Aircraft are made available under an agreement between any manufacturer, vendor, subcontractor or supplier and Lessee, this Section 6 is subject to that agreement. However Lessee will: 1. Pay the proceeds of any claim thereunder to Lessor to be applied pursuant to Section 6.2 and pending such payment will hold the claim and the proceeds on trust for Lessor; and 1. Lessee will take all such steps as are necessary at the end of the Term to ensure the benefit of any of those warranties which have not expired are vested in Lessor. I. LESSOR'S COVENANTS A. Quiet Enjoyment. Lessor will not interfere with the quiet use, possession and enjoyment of the Aircraft by Lessee, but the exercise by Lessor of its rights under or in connection with this Agreement will not constitute such an interference. A. Maintenance Contribution. Provided no Default has occurred and is continuing, Lessor will promptly pay to third party vendors, suppliers, maintenance shops or service facilities, by way of contribution to the cost of maintenance of the Aircraft, upon submission by Lessee to Lessor within six (6) months of the commencement of that maintenance and before the Expiration Date of an invoice (which for this purpose may include such vendor's final estimated invoice issued immediately prior to redelivery to Lessee of the Aircraft so long as Lessee provides Lessor with the final invoice and the relevant maintenance contribution is adjusted to reflect such final invoice as soon as it becomes available) and supporting documentation reasonably satisfactory to Lessor, evidencing with respect to (x) the Airframe, any "C-7" plus SI (formerly "D") check or (y) any Engine or APU, the performance in accordance with this Agreement of a Hot Section Refurbishment, a Cold Section Refurbishment and/or the replacement of Life Limited Parts or (z) any landing gear, work in the nature of overhaul requiring removal and disassembly (in each case, other than (i) repairs arising as a result of foreign object damage or operational or maintenance mishandling and/or (ii) removal, installation, maintenance and repair of QEC (Quick Engine Change) kits; and/or (iii) accomplishment of any airworthiness directives) the lesser of (a) the amount of that invoice and (b) an amount equal to the aggregate amount of Maintenance Reserves paid in respect of the Airframe, that Engine or APU or the Landing Gear under this Agreement, respectively, at the time of commencement of such maintenance less the aggregate amount previously paid in respect of the Airframe, that Engine or APU or the Landing Gear by Lessor under this subsection. Notwithstanding the foregoing to the contrary, if the amount of the Airframe Maintenance Reserves paid by Lessee are insufficient to perform the first "C-7" plus SI (formerly "D") check, Lessor shall contribute to the cost thereof an amount of money up to the sum equal to $80 multiplied by the number of Flight Hours flown by the Aircraft by the previous lessee. A. Lessor Obligations Following Expiration Date. Upon: 1. Redelivery of the Aircraft to Lessor in accordance with and in the condition required by this Agreement; or 1. Payment to Lessor of the Agreed Value following an Event of Loss after the Delivery Date; or in each case such later time as Lessor is satisfied Lessee has irrevocably paid to Lessor all amounts which may then be outstanding or become payable under this Agreement or the Other Agreements and provided that no Default shall have occurred and is continuing, Lessor will pay to Lessee: a) the amount of any Rent received in respect of any period falling after the date of redelivery of the Aircraft or payment of the Agreed Value, as the case may be; and a) the Aircraft Deposit. I. LESSEE'S COVENANTS A. Duration. The obligations in this Section and in Section 12 will: 1. Except as otherwise stated, be performed at the expense of Lessee; and 1. Remain in force until the Expiration Date in accordance with this Agreement and thereafter to the extent of any accrued rights of Lessor in relation to those obligations. A. Information. Lessee will: 1. Notify Lessor forthwith of the occurrence of any Default or any other event which might adversely affect Lessee's ability to perform any of its obligations under this Agreement; 1. Furnish to Lessor: a) on a monthly and quarterly basis, the consolidated unaudited financial statements of Lessee (comprising a balance sheet and profit and loss statement) prepared for the most recent previous month or fiscal quarter, certified by Lessee's chief financial officer as being true and correct; a) as soon as available but not in any event later than one hundred twenty (120) days after the last day of each fiscal year of Lessee, its audited consolidated financial statements for the year ending on such day; a) at the same time as it is issued to the shareholders or creditors of Lessee generally, a copy of each notice or circular issued to Lessee's shareholders or creditors as a group; and a) on request from time to time, such other information relevant to the transactions contemplated by this Agreement regarding Lessee and its business and affairs as Lessor may reasonably request; 1. Keep Lessor informed as to current serial numbers of the Engines and any engine installed on the Aircraft; 1. Promptly furnish to Lessor all information Lessor from time to time reasonably requests regarding the Aircraft, any Engine or any Part, its use, location and condition including, without limitation, the hours available on the Aircraft and any Engine until the next scheduled check, inspection, overhaul or shop visit, as the case may be; 1. On request, within ten (10) days after the end of any Rental Period, furnish to Lessor evidence satisfactory to Lessor of payment of all Taxes due during that or any previous Rental Period; 1.

Provide Lessor with a monthly report (i) on the Flight Hours and Cycles accumulated in respect of the Airframe, each Engine and APU and each Landing Gear during the preceding month in the form required from time to time by Lessor and (ii) removal and/or replacement (whether temporary or otherwise) of any Engine, APU, Landing Gear or other rotable Part during the preceding month in the form required from time to time by Lessor. 1. Give Lessor not less than sixty (60) days' written notice as to the time and location of all Major Checks and provide Lessor prompt notice of any changes in such time and location; and 1. Promptly notify Lessor of: a) Any loss, theft, damage or destruction to the Aircraft, any Engine or any Part, or any modification to the Aircraft if the potential cost may exceed the Damage Notification Threshold; and a) Any claim or other occurrence reasonably likely to give rise to a claim under the Insurance (but in the case of hull claims only in excess of the Damage Notification Threshold) and details of any negotiations with the insurance brokers over any such claim. A. Lawful and Safe Operation. Lessee will: 1. Comply with all laws in force in any country or jurisdiction which may be applicable to the Aircraft or, so far as concerns the use and operation of the Aircraft or an owner or operator thereof and take all reasonable steps to ensure that the Aircraft is not used for any illegal purpose; 1. Not use the Aircraft in any manner contrary to any recommendation of the manufacturer of the Aircraft, any Engine or any Part or any recommendation or regulation of the Air Authority or for any purpose for which the Aircraft is not designed or reasonably suitable; 1. Ensure that the crew and engineers employed by it in connection with the operation and maintenance of the Aircraft have the qualifications and hold the licenses required by the Air Authority and applicable law; 1. Use the Aircraft solely in commercial or other operations for which Lessee is duly authorized by the Air Authority and applicable law; 2.

Not utilize the Aircraft for purposes of training, qualifying or reconfirming the status of cockpit personnel except for the benefit of Lessee's cockpit personnel, and then only if the use of the Aircraft for such purpose is not disproportionate to the use for such purpose of other aircraft of the same type operated by Lessee; 1. Not cause or permit the Aircraft to proceed to, or remain at, any location which is then the subject of a prohibition order (or any similar order or directive), sanctions or restrictions by: a) the United Nations Security Council, the U.S. International Economic Emergency Powers Act or U.N. Security Council directives or the U.S. Export Administration Act Regulations (15 C.F.R. Parts 730-799), except as may be permitted by operating in accordance with the conditions specified by the U.S. Export Administration Regulations, General License GATS (15 C.F.R. Part 771.19); a) any Government Entity of the State of Registration or the Habitual Base; a) any Government Entity of the country in which such location is situated; or a) any Government Entity having jurisdiction over Lessor, the Banks or the Aircraft; 1.

A. Taxes and Other Payments. Lessee will promptly pay: 1. All license and registration fees, Taxes (other than Lessor Taxes) and other amounts of any nature imposed by any Government Entity with respect to the Aircraft, including without limitation the purchase, ownership, delivery, leasing, possession, use, operation, return, sale or other disposition of the Aircraft; and 1. All rent, fees, charges, Taxes (other than Lessor Taxes) and other amounts in respect of any premises where the Aircraft or any Part thereof is located from time to time; except to the extent that in the reasonable opinion of Lessor such payment is being contested in good faith by appropriate proceedings, in respect of which adequate reserves have been provided by Lessee and non-payment of which does not give rise to any material likelihood of the Aircraft or any interest therein being sold, forfeited or otherwise lost or of criminal liability on the part of Lessor or any Bank. A. Sub-Leasing. LESSEE WILL NOT, WITHOUT THE PRIOR WRITTEN CONSENT OF LESSOR, SUB-LEASE OR OTHERWISE PART WITH POSSESSION OF THE AIRCRAFT, THE ENGINES OR ANY PART EXCEPT THAT LESSEE MAY PART WITH POSSESSION (A) WITH RESPECT TO THE AIRCRAFT, THE ENGINES OR ANY PART TO THE RELEVANT MANUFACTURERS FOR TESTING OR SIMILAR PURPOSES OR TO THE AGREED MAINTENANCE PERFORMER FOR SERVICE, REPAIR, MAINTENANCE OR OVERHAUL WORK, OR ALTERATIONS, MODIFICATIONS OR ADDITIONS TO THE EXTENT REQUIRED OR PERMITTED BY THIS AGREEMENT, AND (B) WITH RESPECT TO AN ENGINE OR PART, AS EXPRESSLY PERMITTED BY THIS AGREEMENT; PROVIDED, HOWEVER, WET LEASES SHALL BE PERMITTED. A. Inspection. 1. Lessor and any person designated by Lessor may at any time visit, inspect and survey the Aircraft, any Engine or any Part and may maintain its own technical representative on site throughout any Major Check and for such purpose may, subject to any applicable Air Authority regulation, travel on the flight deck as observer; 1. Lessor will have no duty or liability to make, or arising out of any such visit, inspection or survey; and 1. So long as no Default has occurred and is continuing, Lessor will not exercise such right other than on reasonable notice and so as not to disrupt unreasonably the commercial operations of Lessee. A. Ownership; Property Interests; Related Matters. Lessee will: 1. Not do or knowingly permit to be done or omit or knowingly permit to be omitted to be done any act or thing which might reasonably be expected to jeopardize the rights of Lessor as owner and lessor of the Aircraft; 1. On all occasions when the ownership of the Aircraft, any Engine or any Part is relevant, make clear to third parties that title is held by Lessor; 1. Not at any time (i) represent or hold out Lessor or the Banks as carrying goods or passengers on the Aircraft or as being in any way connected or associated with any operation or carriage (whether for hire or reward or gratuitously) which may be undertaken by Lessee or (ii) pledge the credit of Lessor or the Banks; 1. Ensure that there is always affixed, and not removed or in any way obscured, a fireproof plate (having dimensions of not less than 10 cm. x 7 cm.) in a reasonably prominent position in the cockpit of the Aircraft adjacent to the certificate of airworthiness and on each Engine stating: "This Aircraft/Engine is owned by Interlease Aviation Investors, L.L.C. and is leased to Frontier Airlines, Inc. and may not be operated by any other person without the prior written, consent of Interlease Aviation Investors, L.L.C.;" 1. Not create or permit to exist any Security Interest upon the Aircraft, any Engine or any Part; 1. Not do or permit to be done anything which may reasonably be expected to expose the Aircraft, any Engine or any Part to penalty, forfeiture, impounding, detention, appropriation, damage or destruction and without prejudice to the foregoing, if any such penalty, forfeiture, impounding, detention or appropriation, damage or destruction occurs, give Lessor notice and use best endeavors to procure the immediate release of the Aircraft, any Engine or the Part, as the case may be; 1. Not abandon the Aircraft, the Engine or any Part; 1. Pay and discharge or cause to be paid and discharged when due and payable or make adequate provision by way of security or otherwise for all debts, damages, claims and liabilities which have given or might give rise to a Security Interest over or affecting the Aircraft, any Engine or any Part; and 1. Not attempt, or hold itself out as having any power, to sell, lease or otherwise dispose of the Aircraft, any Engine or any Part. A. General. Lessee will: 1. Not liquidate or dissolve; and Lessee shall not, without Lessor's prior written consent, which will not be unreasonably withheld or delayed, consolidate with or merge into, any other corporation, and Lessee shall not convey, transfer, lease or otherwise dispose of all or substantially all of its property and other assets, whether in one or series of related transactions; 1. Ensure that no change will occur in the Habitual Base of the Aircraft without the prior written consent of Lessor. Lessor agrees that it shall not withhold its consent to a change in the Habitual Base to another state of the United States of America if Lessee shall have provided Lessor with an opinion of counsel practicing in the state of the United States of America proposed by Lessee to be the Habitual Base in form and in substance reasonably satisfactory to Lessor to the effect that the rights and interests of Lessor are duly protected; and 1. Not, without giving Lessor thirty (30) days prior notice (in accordance with this Agreement), change its chief executive office (as such term is defined in Article 9 of the Uniform Commercial Code as in effect in the State of Colorado) from 12015 East 46th Avenue, Denver, Colorado 80239; 1. remain a Certificated Air Carrier and maintain, without limitation, its status so as to fall within the purview of Section 1110 of Title 11 of the United States Code or any analogous Statute; and 1. remain a "citizen of the United States" as defined in Section 40102 of Title 49 of the United States Code. A. Records. Lessee will: 1. Cause accurate, complete and current records of all flights made by, and all maintenance carried out on, the Aircraft (including in relation to each Engine and Part subsequently installed, before the installation) to be prepared in English and kept in such manner as the Air Authority may from time to time require, and ensure that they comply with the recommendations of any manufacturers of the Aircraft, any Engine or any Part. The records will form part of the Aircraft Documents; and 1. Maintain with appropriate revisions, all Aircraft Documents, records, logs, and other materials required by applicable laws and best practice of major international air transport operators in respect of the Aircraft. A. Protection: Lessee will: 1. Maintain the registration of the Aircraft with the Air Authority in the name of Lessor and, to the extent permitted under the laws of the State of Registration, reflecting the interests of Lessor and not do or suffer to be done anything which might adversely affect that registration; and 1. Do all acts and things (including, without limitation, making any filing or registration with the Air Authority or any other Government Entity) and execute and deliver, notarize, file, register and record all documents (including, without limitation, any amendment of this Agreement) as may be required by Lessor: a) at Lessor's expense, following any change or proposed change in the ownership or financing of the Aircraft or in the manner of securing Lessor's obligations to the Banks; or a) following any modification of the Aircraft, any Engine or any Part or the permanent replacement of any Engine or Part in accordance with this Agreement, so as to ensure that the rights of Lessor as owner and lessor of the Aircraft and under this Agreement apply with the same effect as before; or a) to establish, maintain, preserve, perfect and protect the rights of Lessor under this Agreement or the interest of Lessor as owner of the Aircraft. A. Maintenance and Repair. Lessee, at its own cost and expense, will: 1. Service, repair, maintain, overhaul, test, or cause the same to be done to the Aircraft, to industry standard, and in accordance with the Agreed Maintenance Program, so as to keep the Aircraft in as good operating condition as when delivered to Lessee on the Delivery Date, as determined periodically by Lessor or its agent, and such operating condition as may be necessary to enable the Airworthiness Certificate of the Aircraft to be maintained in good standing at all times under applicable law; 1. Not change the Agreed Maintenance Program or the schedule of the Agreed Maintenance Program without the written consent of Lessor; 1. Maintain the Aircraft in accordance with the Agreed Maintenance Program through the Agreed Maintenance Performer and perform (at the respective intervals provided in the Agreed Maintenance Program) all Major Checks; 1. Maintain the Aircraft in accordance with FAA Federal Air Regulations Part 121 and any other rules and regulations of the FAA as may be applicable to passenger category aircraft and in at least the same manner and with at least the same care, including, without limitation, maintenance scheduling, modification status and technical condition, as is the case with respect to similar aircraft owned or otherwise operated by Lessee and as if Lessee were to retain the Aircraft in its fleet and continue to operate the Aircraft after the Expiration Date and including, without limitation, all maintenance to the Airframe, any Engine or any Part required to maintain all warranties, performance guarantees or service life policies in full force and effect; 1. Without limiting Lessor's obligations under clause (d) of Schedule 1, Part 1, to this Agreement, comply with all outstanding mandatory inspection and modification requirements, airworthiness directives and similar requirements applicable to the Aircraft, any Engine or Part which are issued prior to the Expiration Date and have a mandatory compliance date during the Term or within one hundred eighty (180) days after the Expiration Date and which are required by the Air Authority, and/or the laws of the state of manufacture of the Aircraft, any Engine or Part and/or mandated by any manufacturer of the Aircraft, any Engine or Part (each of the foregoing being hereinafter referred to as "AD"). The cost of each AD accomplishment or repetitive AD accomplishment for any AD issued during the Term shall be allocated among Lessor and Lessee as follows: (i) Lessee shall be responsible for the first $150,000 of Lessee's actual cost of such AD accomplishment or repetitive AD accomplishment; (ii) Lessor and Lessee shall share the portion of Lessee's actual cost of such AD accomplishment or repetitive AD accomplishment (if any) which exceeds $150,000, on an equal basis, up to and including $350,000; and (iii) Lessor shall be wholly responsible for the portion of Lessee's actual cost of such AD accomplishment or repetitive AD accomplishment (if any) which exceeds $350,000 (subject always to the provisions of the following paragraph). Notwithstanding the foregoing, in the event that the total cost of any AD accomplishment or repetitive AD accomplishment (such total cost to be mutually agreed, in good faith, between Lessor and Lessee) exceeds $350,000 (the "Threshold Amount"), Lessor may elect not to make its contribution to the cost of compliance with such AD accomplishment or repetitive AD accomplishment as described above. If Lessor shall so elect, Lessee shall be entitled, by giving prior written notice to Lessor, to terminate this Agreement and redeliver the Aircraft to Lessor in accordance with the terms of Sections 12.1 through 12.8 and Schedule 3 (except for compliance with the relevant AD which gave rise to such termination) on the earlier of (x) the date which is 30 days after the date of such notice from Lessee to Lessor or (y) the date on which the Aircraft is required to be removed from service by reason of non-compliance with the applicable AD. Such notice shall specify the proposed redelivery date of the Aircraft by Lessee and, upon the receipt of such notice by Lessor, the then current definition of Expiration Date shall be deemed to have been amended accordingly. Upon any termination of this Agreement pursuant to this Section 8.11(e), neither party shall be under any further obligation in the other hereunder except for (x) accrued obligations of Lessee hereunder; and (y) obligations hereunder which are expressed to continue notwithstanding the expiration of the Term; provided, however, that Lessor shall, if applicable having regard to the provisions of Section 7.2, make the payments described in Section 7.2 but shall be under no obligation to repay, rebate or otherwise refund any Maintenance Reserves previously paid by Lessee under this Agreement and provided further that if no Default shall have occurred and be continuing, the Aircraft Deposit shall be returned by Lessor to Lessee. 1. Comply with all applicable laws and the regulations of the Air Authority and other aviation authorities with jurisdiction over Lessee or the Aircraft, any Engine or Part regardless of upon whom such requirements are imposed and which relate to the maintenance, condition, use or operation of the Aircraft or require any modification or alteration to the Aircraft, any Engine or Part; 1. Maintain in good standing a current certificate of airworthiness (in the appropriate category for the nature of the operations of the Aircraft) for the Aircraft issued by the Air Authority except where the Aircraft is undergoing maintenance, modification or repair required or permitted by this Agreement and will from time to time provide to Lessor a copy on request; 1. If required by the Air Authority, maintain a current certification as to maintenance issued by or on behalf of the Air Authority in respect of the Aircraft and will from time to time provide to Lessor a copy on request; and 1. Procure promptly the replacement of any Engine or Part which has become time, cycle or calendar expired, lost, stolen, seized, confiscated, destroyed, damaged beyond repair, unserviceable or permanently rendered unfit for use, with an engine or part complying with the conditions set out in Section 8.13(a). A. Remova of Engines and Parts. Lessee will ensure that no Engine or Part installed on the Aircraft is at any time removed from the Aircraft other than: 1. If replaced as expressly permitted by this Agreement; or 1. If the removal is of an obsolete item and is in accordance with the Agreed Maintenance Program; or a) During the course of maintaining, servicing, repairing, overhauling or testing that Engine or the Aircraft, as the case may be; or a) For the purpose of making such modifications to the Engine or the Aircraft, as the case may be, as are permitted under this Agreement; and then in each case only if it is reinstalled or replaced by an engine or part complying with Section 8.13(a) as soon as possible and in any event no later than the Expiration Date. A. Installation of Engines and Parts. Lessee will: 1. Ensure that, except as permitted by this Agreement, no engine or part is installed on the Aircraft unless: a) in the case of an engine, it is an engine of the same model as, or an improved or advanced version of the Engine it replaces, which is in the same or better operating condition, has substantially similar hours and cycles available until the next scheduled checks, inspections, overhauls, shop visits and replacement of life limited components and has the same or greater value and utility as the replaced Engine; a) in the case of a part, it is in as good operating condition, has substantially similar hours available until the next scheduled checks, inspections, overhauls and shop visits, is of the same or a more advanced make and model and is of the same interchangeable modification status as the replaced Part; a) in each case, it has become and remains the property of Lessor free from Security Interests and on installation on the Aircraft will without further act be subject to this Agreement; and a) in each case, Lessee has full details as to its source and maintenance records; 1. If no Default has occurred which is continuing, be entitled to install any engine or part on the Aircraft by way of replacement notwithstanding Section 8.13(a) if: a) there is not available to Lessee at the time and in the place that that engine or part is required to be installed on the Aircraft, a replacement engine or, as the case may be, part complying with the requirements of Section 8.13(a); a) it would result in an unreasonable disruption of the operation of the Aircraft and/or the business of Lessee to ground the Aircraft until an engine or part, as the case may be, complying with Section 8.13(a) becomes available for installation on the Aircraft; a) Lessee gives Lessor written notice of such replacement contemporaneously with such installation; and a) as soon as possible after installation of the same on the Aircraft but, in any event, no later than sixty (60) days thereafter (but in no event later than the Expiration Date), Lessee removes any such engine or part and replaces it with the Engine or Part replaced by it or by an engine or part, as the case may be, complying with Section 8.13(a). A. Non-Installed Engines and Parts. Lessee will: 1. Ensure that any Engine or Part which is not installed on the Aircraft (or any other aircraft as permitted by this Agreement) is, except as expressly permitted by this Agreement, properly and safely stored, and kept free from Security Interests; 1. Notify Lessor whenever any Engine is removed from the Aircraft and, from time to time on request, ensure that any person to whom possession of an Engine is given acknowledges in writing to Lessor, in form and substance satisfactory to Lessor, that it will respect the interests of Lessor and as owner of the Engine and will not seek to exercise any rights whatsoever in relation to it; 1. Notwithstanding the foregoing provisions of this subsection, be permitted, if no Default has occurred and is continuing, to install any Engine or Part on an aircraft, or in the case of a Part, an engine for a temporary period of up to thirty (30) days: a) owned and operated by Lessee free from Security Interests; or a) leased or hired to Lessee pursuant to a lease or conditional sale agreement on a long-term basis and on terms whereby Lessee has full operational control of that aircraft or engine; or a) acquired by Lessee and/or financed or refinanced, and operated by Lessee, on terms that ownership of that aircraft or engine, as the case may be, pursuant to a lease or conditional sale agreement, or a Security Interest therein, is vested in or held by any other person; provided that in the case of (ii) and (iii): (i) the terms of any such lease, conditional sale agreement or Security Interest will not have the effect of prejudicing the interests of Lessor as owner and lessor of that Engine or Part; and (i) the lessor under such lease, the seller under such conditional sale agreement or the holder of such Security Interest, as the case may be, has confirmed and acknowledged in writing to Lessor, in form and substance satisfactory to Lessor, that it will respect the interest of Lessor as owner and lessor of that Engine or Part and that it will not seek to exercise any rights whatsoever in relation thereto. A. Pooling of Engines and Parts. Lessee will not enter into nor permit any pooling agreement or arrangement in respect of an Engine or Part without the prior written consent of Lessor. A. Equipment Changes. 1. Lessee will not make any modification or addition to the Aircraft (each an "Equipment Change"), except for an Equipment Change which: a) is expressly permitted by this Agreement, or a) has the prior written approval of Lessor and which does not diminish the value, utility, condition, or airworthiness of the Aircraft; and 1. So long as a Default has not occurred and is continuing, Lessee may remove any Equipment Change if it can be removed from the Aircraft without diminishing or impairing the value, utility, condition or airworthiness of the Aircraft. A. Title on an Equipment Change. 1. Title to all Engines and Parts installed on the Aircraft whether by way of replacement, as the result of an Equipment Change or otherwise (except those installed pursuant to Section 8.13(b)) will on installation, without further act, vest in Lessor subject to this Agreement free and clear of all Security Interests. Lessee will at its own expense take all such steps and execute, and procure the execution of, all such instruments as Lessor may require and which are necessary to ensure that title so passes to Lessor according to all applicable laws. At any time when requested by Lessor, Lessee will provide evidence to Lessor's satisfaction (including the provision, if required, to Lessor of one or more legal opinions) that title has so passed to Lessor; 1. Lessor may require Lessee to remove any Equipment Change and to restore the Aircraft to its condition prior to that Equipment Change; and 1. Except as referred to in Section 8.17(b) any Engine or Part at any time removed from the Aircraft will remain the property of Lessor until a replacement has been made in accordance with this Agreement and until title in that replacement has passed, according to applicable laws, to Lessor subject to this Agreement free of all Security Interests whereupon title to the replaced Engine or Part will pass to Lessee. B. Third Party. Lessee will ensure that no person (other than Lessor or any Bank) will act in any manner inconsistent with its obligations under this Agreement and that all persons will comply with those obligations as if references to "Lessee" included a separate reference to those persons. I. INSURANCE A. Insurance. Lessee will maintain in full force during the Term insurance in respect of the Aircraft in form and substance satisfactory to Lessor (the "Insurance", which expression includes, where the context so admits, any relevant re-insurance(s)) through such brokers and with such insurers and having such deductibles and being subject to such exclusions as may be approved by Lessor. The Insurance will be effected either: (a) on a direct basis with insurers of recognized standing who normally participate in aviation insurance in the leading international insurance markets and led by reputable underwriter(s) approved by Lessor; or (b) with a single insurer or group of insurers approved by Lessor who does not retain the risk but effects substantial reinsurance with reinsurers in the leading international insurance markets and through brokers each of recognized standing and acceptable to Lessor for a percentage acceptable to Lessor of all risks insured (the "Reinsurance"). A. Requirements. Lessor's current requirements as to required Insurance are as specified in this Section and in Schedule 4. Lessor may from time to time stipulate other requirements for the Insurance so that the scope and level of cover is maintained in line with best industry practice and the interests of Lessor protected. A. Change. If at any time Lessor wishes to revoke its approval of any insurer, reinsurer, insurance or reinsurance, Lessor and/or its brokers will consult with Lessee and Lessee's brokers (as for the time being approved by Lessor) regarding whether that approval should be revoked to protect the interests of the parties insured. If, following the consultation, Lessor considers that any change should be made, Lessee will then arrange or procure the arrangement of alternative cover satisfactory to Lessor. A. Insurance Covenants. Lessee will: 1. Ensure that all legal requirements as to insurance of the Aircraft, any Engine or any Part which may from time to time be imposed by the laws of the State of Registration or any state to, from or over which the Aircraft may be flown, in so far as they affect or concern the operation of the Aircraft, are complied with and in particular those requirements compliance with which is necessary to ensure that (i) the Aircraft is not in danger of detention or forfeiture, (ii) the Insurance remain valid and in full force and effect, and (iii) the interests of the Indemnitees in the Insurance and the Aircraft or any Part are not thereby prejudiced; 1. Not use, cause or permit the Aircraft, any Engine or any Part to be used for any purpose or in any manner not covered by the Insurance or outside any geographical limit imposed by the Insurance; 1. Comply with the terms and conditions of each policy of the Insurance and not do, consent or agree to any act or omission which: a) invalidates or may invalidate the Insurance; or a) renders or may render void or voidable the whole or any part of any of the Insurance; or a) brings any particular liability within the scope of an exclusion or exception to the Insurance; 1. Not take out without the prior written approval of Lessor any insurance or reinsurance in respect of the Aircraft other than those required under this Agreement unless relating solely to hull total loss, business interruption, profit commission and deductible risk; 1. Commence renewal procedures at least thirty (30) days prior to expiration of any of the Insurance and provide to Lessor: a) if requested by Lessor, a written status report of renewal negotiation 14 days prior to each expiration date; a) facsimile confirmation of completion of renewal prior to each expiration date; a) certificates of insurance (and where appropriate certificates of reinsurance), and broker's (and any reinsurance brokers') letter of undertaking in a form acceptable to Lessor, detailing the coverage and confirming the insurers' (and any reinsurers') agreement to the specified insurance requirements of this Agreement within seven (7) days after each renewal date; 1. Provide to Lessor copies of documents evidencing the Insurance; 1. Provide to Lessor evidence that the Insurance premiums have been paid; 2. Not make any modification or alteration to the Insurance material and adverse to the interests of any of the Indemnitees; 1. Be responsible for any deductible under the Insurance; and 1. Provide any other insurance and reinsurance related information, or assistance, in respect of the Insurance as Lessor may reasonably require. A. Failure to Insure. If Lessee fails to maintain the Insurance in compliance with this Agreement, each of the Indemnitees will be entitled but not bound (without prejudice to any other rights of Lessor under this Agreement): 1. To pay the premiums due or to effect and maintain insurance satisfactory to it or otherwise remedy Lessee's failure in such manner (including, without limitation to effect and maintain an "owner's interest" policy) as it considers appropriate. Any sums so expended by it will become immediately due and payable by Lessee to Lessor together with interest thereon at the rate specified in Section 5.11, from the date of expenditure by it up to the date of reimbursement by Lessee; and 1. At any time while such failure is continuing to require the Aircraft to remain at any airport or to proceed to and remain at any airport designated by it until the failure is remedied to its satisfaction. A. Continuing Indemnity. Lessor may require Lessee to effect and to maintain insurance after the Expiration Date with respect to its liability under the indemnities in Section 10 for such period as Lessor may reasonably require (but in any event not more than two (2) years) which provides for each Indemnitee to be named as additional insured. Lessee's obligation in this Section shall not be affected by Lessee ceasing to be lessee of the Aircraft and/or any of the Indemnitees ceasing to have any interest in respect of the Aircraft. A. Application of Insurance Proceeds. As between Lessor and Lessee: 1. All insurance payments received as the result of an Event of Loss occurring during the Term will be paid to Lessor, and Lessor will pay the balance of those amounts to Lessee after deduction of all amounts which may be or become payable by Lessee to Lessor under this Agreement (including under Section 11.1(b)); 1. All insurance proceeds of any property damage or loss to the Aircraft, any Engine or any Part occurring during the Term not constituting an Event of Loss and in excess of the Damage Notification Threshold will be paid to Lessor and applied in payment (or to reimburse Lessee) for repairs or replacement property upon Lessor being satisfied that the repairs or replacement have been effected in accordance with this Agreement. Insurance proceeds in amounts below the Damage Notification Threshold may be paid by the insurer directly to Lessee. Any balance remaining may be retained by Lessor; 1. All insurance proceeds in respect of third party liability will, except to the extent paid by the insurers to the relevant third party, be paid to Lessor to be paid directly in satisfaction of the relevant liability or to Lessee in reimbursement of any payment so made; and 1. Notwithstanding Sections 9.7(a), (b) or (c), if at the time of the payment of any such insurance proceeds a Default has occurred and is continuing, all such proceeds will be paid to or retained by Lessor to be applied toward payment of any amounts which may be or become payable by Lessee in such order as Lessor sees fit or as Lessor may elect. I. INDEMNITY A. General. Lessee agrees to assume liability for, defend, indemnify and hold harmless the Indemnitees on an after tax basis from and against any and all claims, proceedings, losses, liabilities, damages (whether direct, indirect, special, incidental or consequential) suits, judgments, costs, expenses (including, without limitation, legal fees and expenses), penalties (whether civil or criminal) or fines (each a "Claim") (regardless of when the same is made or incurred, whether during or after the Term (but not before)): 1. Which may at any time be suffered or incurred directly or indirectly as a result of or in any manner connected with the possession, delivery, performance, management, ownership, registration, control, maintenance, condition, service, repair, overhaul, leasing, use, operation or return of the Aircraft, any Engine or Part (either in the air or on the ground) whether or not the Claim may be attributable to any defect in the Aircraft, any Engine or any Part or to its design, testing or use or otherwise, and regardless of when the same arises or whether it arises out of or is attributable to any act or omission, negligent or otherwise, of any Indemnitee; or 1. Which arise out of any act or omission which invalidates or which renders voidable any of the Insurance; or 1. Which may at any time be suffered or incurred as a consequence of any design, article or material in the Aircraft, any Engine or any Part or its operation or use constituting an infringement of patent, copyright, trademark, design or other proprietary right or a breach of any obligation of confidentiality owed to any person; or 1. Which results from Lessee's breach of any of its representations or warranties or any other Event of Default under this Agreement. but excluding any Claim in relation to a particular Indemnitee to the extent that that Claim is covered pursuant to another indemnity provision of this Agreement or to the extent it arises solely as a result of the negligence or wilful misconduct of that Indemnitee, Lessor, Lessor Taxes or a Lessor Lien. A. Duration. The indemnities contained in this Agreement will continue in full force after the Expiration Date. I. EVENTS OF LOSS A. Events of Loss. 1. If an Event of Loss occurs prior to delivery of the Aircraft to Lessee, Lessor will have the option, exercisable by giving Lessee notice in writing, to substitute an alternative aircraft of the same manufacture, model, value and utility as the Aircraft. If Lessor exercises such option, Lessee shall be obliged to lease such substitute aircraft pursuant to the terms and conditions of this Agreement and such substitute aircraft shall constitute the Aircraft for all purposes of this Agreement. Lessor shall provide Lessee with details of the substitute aircraft as soon as may be practicable after the occurrence of the Event of Loss. If Lessor advises Lessee that Lessor does not wish to exercise such option, this Agreement will immediately terminate and except as expressly stated in this Agreement neither party will have any further obligation or liability under this Agreement other than pursuant to Section 16.90 except that Lessor will rebate to Lessee the amount of any Aircraft Deposit paid under this Agreement; and 1. If an Event of Loss occurs after delivery of the Aircraft to Lessee, Lessee will pay the Agreed Value to Lessor on or prior to the earlier of (i) five (5) Business Days after the Event of Loss and (ii) the date of receipt of insurance proceeds in respect of that Event of Loss. Subject to the rights of any insurers and reinsurers or other third party, upon irrevocable payment in full to Lessor of that amount and all other amounts which may be or become payable to Lessor under this Agreement, Lessor will without recourse or warranty (except as to Lessor's Liens) and without further act, be deemed to have transferred to Lessee all of Lessor's rights to any Engines and Parts not installed when the Event of Loss occurred, all on an as-is where-is basis, and will at Lessee's expense, execute and deliver such bills of sale and other documents and instruments as Lessee may reasonably request to evidence (on the public record or otherwise) the transfer and the vesting of Lessor's rights in such Engines and Parts in Lessee, free and clear of all rights of Lessor and Lessor Liens. A. Requisition. During any requisition for use or hire of the Aircraft, any Engine or Part which does not constitute an Event of Loss: 1. The Rent, Supplemental Rent and other charges payable under this Agreement will not be suspended or abated either in whole or in part, and Lessee will not be released from any of its other obligations under the Agreement (other than operational obligations with which Lessee is unable to comply solely by virtue of the requisition); and 1. So long as no Default has occurred and is continuing, Lessee will be entitled to any hire paid by the requisitioning authority in respect of the Term. Lessee will, as soon as practicable after the end of any such requisition, cause the Aircraft to be put into the condition required by this Agreement. Lessor will be entitled to all compensation payable by the requisitioning authority in respect of any change in the structure, state or condition of the Aircraft arising during the period of requisition, and Lessor will apply such compensation in reimbursing Lessee for the cost of complying with its obligations under this Agreement in respect of any such change, but so that, if any Default has occurred and is continuing, Lessor may apply the compensation or hire in or towards settlement of any amounts owing by Lessee under this Agreement. I. RETURN OF AIRCRAFT A. Return. On the Expiration Date or earlier termination of the lease of the Aircraft under this Agreement, unless an Event of Loss has occurred, and after the Final Inspection required by Section 12.2 has occurred, Lessee will, at its expense, redeliver the Aircraft and Aircraft Documents to Lessor at the Redelivery Location or such other airport as is mutually acceptable to the parties hereto, in a condition complying with Schedule 3, free and clear of all Security Interests and Permitted Liens (other than Lessor Liens) and in a condition qualifying for immediate certification of airworthiness by the FAA or as otherwise agreed by Lessor and Lessee. A. Final Inspection. Immediately prior to redelivery of the Aircraft, Lessee will make the Aircraft available to Lessor for detailed inspection ("Final Inspection") in order to verify that the condition of the Aircraft complies with the requirements of Schedule 3 to this Agreement. The Final Inspection will be long enough to permit Lessor to: 1. Inspect the Aircraft Documents; 1. Inspect the Aircraft and uninstalled Parts; 1. Inspect the Engines, including without limitation (i) at Lessor's expense, a video boroscope inspection of (A) the low pressure and high pressure compressors and (B) turbine area and (ii) at Lessee's expense, engine condition runs; and 1. Observe a two (2) hour test flight (with Lessor's representatives as on-board observers). Such test flight shall be conducted by Lessee using the aircraft manufacturer's recommended test flight procedures. The Lessee shall provide, at Lessee's cost, insurance on the aircraft hull and liability and for the representatives of the Lessor during the test flight. Lessor shall be permitted to have a minimum of two (2) representatives attend the Inspection and/or test flight. The Lessee shall be required to open any areas of the Aircraft requested to be opened by the Lessor or its representative in order to verify any aspect of its condition, including but not limited to the opening of the galley area, the lavatories and the lower cargo compartment bilges. The Final Inspection shall commence on or before the Expiration Date with respect to the Aircraft and shall continue until concluded. A. Non-Compliance. To the extent that, at the time of Final Inspection, the condition of the Aircraft does not comply with this Agreement, Lessee will at Lessor's option: 1. Immediately rectify the non-compliance and to the extent the non-compliance extends beyond the Expiration Date, the Term (and Lessee's obligation to pay Rent) will be automatically extended and this Agreement will remain in force until the non-compliance has been rectified; or 1. Redeliver the Aircraft to Lessor and indemnify Lessor, and provide to Lessor's satisfaction cash as security for that indemnity, against the cost of putting the Aircraft into the condition required by this Agreement. A. Intentionally Omitted. A. Acknowledgement. Provided Lessee has complied with its obligations under this Agreement, following redelivery of the Aircraft by Lessee to Lessor at the Redelivery Location, Lessor will deliver to Lessee an acknowledgement confirmin that Lessee has redelivered the Aircraft to Lessor in accordance with this Agreement. B. Maintenance Program. 1. Prior to the Expiration Date and upon Lessor's request, Lessee will provide Lessor or its agent reasonable access to the Agreed Maintenance Program and the Aircraft Documents in order to facilitate the Aircraft's integration into any subsequent operator's fleet; 1. Lessee will, if requested by Lessor to do so, upon return of the Aircraft deliver to Lessor a certified true current and complete copy of the Agreed Maintenance Program, together with a letter authorizing Lessor to use such copy for "bridging" purposes for the next lessee of the Aircraft. Lessor agrees that it will not disclose the contents of the Agreed Maintenance Program to any person or entity except to the extent necessary to monitor Lessee's compliance with this Agreement and/or to bridge the maintenance program for the Aircraft from the Agreed Maintenance Program to another program after the Expiration Date. A. Fuel. Upon redelivery of the Aircraft to Lessor, an adjustment will be made in respect of fuel on board on the Delivery Date and the Expiration Date at the price then prevailing at the Redelivery Location. A. Aircraft Storage. During the period of thirty (30) days after the Expiration Date, Lessor shall have the right to require Lessee to maintain, store and insure the Aircraft at a location having a facility capable of performing required maintenance of the Aircraft (to be mutually agreed by Lessor and Lessee). All costs actually paid by Lessee to any third party vendor in connection with the foregoing shall be payable by Lessor at Lessee's direct cost without "mark-up". At least thirty (30) days prior to the Expiration Date, Lessor shall advise Lessee as to whether Lessor requires Lessee to provide the services contemplated by this Section 12.8. I. DEFAULT A. Events of Default. Each of the following events or conditions will constitute an Event of Default (whether any such event or condition is voluntary or involuntary or occurs by operation of law or pursuant to or in compliance with any judgment, decree or order of any court or any order, rule or regulation of any Government Entity): 1. Non-Payment. Lessee fails to make any payment under this Agreement on the due date and such failure continues for two (2) Business Days; or 1. Insurance. Lessee fails to comply with any provision of Section 9 or any insurance required to be maintained under this Agreement is cancelled or terminated or notice of cancellation is given in respect of any such insurance; or 1. Breach. Lessee fails to comply with any other provision of this Agreement and, if such failure is in the reasonable opinion of Lessor capable of remedy, the failure continues for five (5) Business Days after notice from Lessor to Lessee; or 1. Representation. Any representation or warranty made (or deemed to be repeated) by Lessee in or pursuant to this Agreement or in any document or certificate or statement is or proves to have been incorrect in any material respect when made or deemed to be repeated; or 1.

By notice to Lessee and with immediate effect, terminate this lease of the Aircraft (but without prejudice to the continuing obligations of Lessee under this Agreement), whereupon all rights of Lessee under this Agreement shall cease; and/or 1. Proceed by appropriate court action or actions to enforce performance of this Agreement or to recover damages for the breach of this Agreement; and/or 1. Either: a) Take possession of the Aircraft, for which purpose Lessor may enter any premises belonging to or in the occupation of or under the control of Lessee where the Aircraft may be located, or cause the Aircraft to be redelivered to Lessor at Chicago, Illinois (or such other location as Lessor may require), and Lessor is hereby irrevocably by way of security for Lessee's obligations under this Agreement appointed attorney for Lessee in causing the redelivery or in directing the pilots of Lessee or other pilots to fly the Aircraft to that airport and will have all the powers and authorizations necessary for taking that action; or a) By serving notice require Lessee to redeliver the Aircraft to Lessor at Chicago, Illinois (or such other location as Lessor may require). Further, in the event that Lessee fails to redeliver the Aircraft to Lessor pursuant to Lessor's written notice and Lessor seeks a judicial order of replevin, attachment or similar remedy, to the extent permitted by applicable law, Lessee hereby waives the posting of any bond by Lessor in connection therewith. A. Deregistration. If an Event of Default occurs, Lessor may sell or otherwise deal with the Aircraft free and clear of any leasehold or other interest of Lessee as if this Agreement had never been made and Lessee will, at the request of Lessor, take all steps necessary to effect (if applicable) deregistration of the Aircraft and its export from the country where the Aircraft is situated and any other steps necessary to enable the Aircraft to be delivered, at Lessor's option, outside the United States; Lessee hereby irrevocably and by way of security for its obligations under this Agreement appoints (which appointment is coupled with an interest) Lessor as its attorney to execute and deliver any documentation and to do any act or thing required in connection with the foregoing. A. Default Payments. If: 1. A Default occurs; or 1. The Aircraft is not delivered on the proposed Delivery Date by reason of failure of Lessee to satisfy any conditions to that delivery; Lessee will indemnify Lessor on demand against any loss (including loss of profit), damage, expense, cost or liability which Lessor may sustain or incur directly or indirectly as a result including but not limited to: (a) Any loss of profit suffered by Lessor because of Lessor's inability to place the Aircraft on lease with another lessee on terms as favorable to Lessor as this Agreement or because whatever use, if any, to which Lessor is able to put the Aircraft upon its return to Lessor, or the funds arising upon a sale or other disposal of the Aircraft, is not as profitable to Lessor as this Agreement; (b) Any amount of principal, interest, fees or other sums whatsoever paid or payable on account of funds borrowed in order to carry any unpaid amount; (c) Any loss, premium, penalty or expense which may be incurred in repaying funds raised to finance the Aircraft or in unwinding any swap, forward interest rate agreement or other financial instrument relating in whole or in part to Lessor's financing of the Aircraft; and (d) Any loss, cost, expense or liability sustained or incurred by Lessor owing to Lessee's failure to redeliver the Aircraft on the date, at the place and in the condition required by this Agreement. I. ASSIGNMENT A. LESSEE WILL NOT ASSIGN, TRANSFER (VOLUNTARILY OR INVOLUNTARILY BY OPERATION OF LAW OR OTHERWISE) OR CREATE OR PERMIT TO EXIST ANY SECURITY INTEREST IN, TO OR UNDER, ANY OF ITS RIGHTS UNDER THIS AGREEMENT. A. Lessor at its expense may assign or transfer all or any of its rights under this Agreement and in the Aircraft, provided that Lessor will in the case of an assignment other than by way of security have no further obligation under this Agreement following the assignment of all its rights under this Agreement and the assumption by the assignee or transferee of all of Lessor's obligations under this Agreement, but notwithstanding that assignment will remain entitled to the benefit of each indemnity and the liability insurances effected under this Agreement. Lessee will comply with all reasonable requests of Lessor, its successors and assigns in respect of any such assignment, and Lessor will promptly notify Lessee of any such assignment. A. If Lessor desires to effect any assignment or transfer of its rights and obligations under this Agreement, Lessee at Lessor's expense agrees to cooperate and take all such steps as Lessor may reasonably request to give the transferee the benefit of this Agreement. I. ILLEGALITY If it is or becomes unlawful in any jurisdiction for Lessor to give effect to any of its material obligations as contemplated by this Agreement or to continue this Agreement Lessor may by notice in writing to Lessee terminate the leasing of the Aircraft under this Agreement and Lessee will forthwith redeliver the Aircraft to Lessor in accordance with Section 12. Without prejudice to the foregoing Lessor will consult in good faith with Lessee as to any steps which may be taken to restructure the transaction to avoid that unlawfulness but will be under no obligation to take any such steps. I. MISCELLANEOUS A. Waivers, Remedies Cumulative. The rights of Lessor under this Agreement: 1. May be exercised as often as necessary; 1. Are cumulative and not exclusive of its rights under any law; and 1. May be waived only in writing and specifically. Delay in exercising or non-exercise of any such right will not constitute a waiver of that right. A. Delegation. Lessor may delegate to any person or persons all or any of the trusts, powers or discretions vested in it by these presents and any such delegation may be made upon such terms and conditions and subject to such regulations (including power to sub-delegate) as Lessor in its absolute discretion thinks fit. A. Certificates. Except where expressly provided in this Agreement, any certificate or determination by Lessor as to any rate of interest or as to any other amount payable under this Agreement will, in the absence of manifest error, be conclusive and binding on Lessee. A. Appropriation. If any sum paid or recovered in respect of the liabilities of Lessee under this Agreement is less than the amount then due, Lessor may apply that sum to amounts due under this Agreement in such proportions and order and generally in such manner as Lessor may determine at its sole discretion. A. Not Used. A. Set-off. Lessor may set off any matured obligation owed by Lessee under this Agreement or the Other Agreements (to the extent beneficially owned by Lessor) against any obligation (whether or not matured) owed by Lessor to Lessee, regardless of the place of payment or currency. If an obligation is unascertained or unliquidated, Lessor may in good faith estimate that obligation and set off in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained or liquidated. Lessor will not be obliged to pay any amounts to Lessee under this Agreement so long as any sums which are then due from Lessee under this Agreement or the Other Agreements remain unpaid and any such amounts which would otherwise be due will fall due only if and when Lessee has paid all such sums except to the extent Lessor otherwise agrees or sets off such amounts against such payment pursuant to the foregoing. A. Severability. If a provision of this Agreement is or becomes illegal, invalid or unenforceable in any jurisdiction, that will not affect: 1. The legality, validity or enforceability in that jurisdiction of any other provision of this Agreement; or 1. The legality, validity or enforceability in any other jurisdiction of that or any other provision of this Agreement. A. Remedy. If Lessee fails to comply with any provision of this Agreement, Lessor may, without being in any way obliged to do so or responsible for so doing and without prejudice to the ability of Lessor to treat the non-compliance as a Default or an Event of Default, effect compliance on behalf of Lessee, whereupon Lessee shall become liable to pay immediately any sums expended by Lessor together with all costs and expenses (including legal costs) in connection therewith. A. Expenses. Whether or not the Aircraft is delivered to Lessee (except where such delivery is prevented by the act of Lessor) pursuant to this Agreement, Lessee will pay to Lessor on demand all expenses (including legal, survey and other costs) payable or incurred by Lessor in contemplation of, or otherwise in connection with, the enforcement of or preservation of any of Lessor's rights under this Agreement, or in respect of the repossession of the Aircraft. All expenses payable pursuant to this Section 16.9 will be paid as they are incurred by Lessor. A. Time of Essence. The time stipulated in this Agreement for all payments payable by Lessee to Lessor and for the performance of Lessee's other obligations under this Agreement will be of the essence of this Agreement.
