Section 2.2 Making the Advances. (a) Interest Advances shall be made in one or more Borrowings by delivery to the Liquidity Provider of one or more written and completed Notices of Borrowing in substantially the form of Annex I attached hereto, signed by a Responsible Officer of the Borrower, in an amount not exceeding the Available Commitment at such time and shall be used solely for the payment when due of interest on the Class B Certificates at the Stated Interest Rate therefor in accordance with Section 3.6(a) of the Intercreditor Agreement. Each Interest Advance made hereunder shall automatically reduce the Available Commitment and the amount available to be borrowed hereunder by subsequent Advances by the amount of such Interest Advance (subject to reinstatement as provided in the next sentence). Upon repayment to the Liquidity Provider in full of the amount of any Interest Advance made pursuant to this Section 2.2(a), together with accrued interest thereon (as provided herein), the Available Commitment shall be reinstated by the amount of such repaid Interest Advance; provided, however, that the Available Commitment shall not be so reinstated at any time if (x) both (i) a Triggering Event shall have occurred and be continuing and (ii) a Performing Note Deficiency exists or (y) a Liquidity Event of Default shall have occurred and be continuing. (b) A Downgrade Advance shall be made in a single Borrowing upon a downgrading of the rating of the Liquidity Provider resulting in the Liquidity Provider's ratings not meeting the Threshold Rating (as provided for in Section 3.6(c) of the Intercreditor Agreement) unless a Replacement Liquidity Facility shall have been delivered to the Borrower in accordance with said Section 3.6(c), by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex II attached hereto, signed by a Responsible Officer of the Borrower, in an amount not exceeding the Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account in accordance with said Section 3.6(c). The Liquidity Provider shall promptly notify the Borrower of any downgrade of its unsecured debt rating by Moody's or Standard & Poor's below the applicable Threshold Rating. (c) A Final Advance shall be made by the Liquidity Provider without the necessity for a Notice of Borrowing at the option of the Liquidity Provider on the occurrence of an event described in Section 6.1(a) or 6.1(b) in an amount equal to the Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account. (d) Each Borrowing (other than under Section 2.2(c)) shall be made on notice in writing (a "Notice of Borrowing") in 6 10 substantially the form required by Section 2.2(a) or 2.2(b), as the case may be, given not later than 12:00 Noon (New York City time) on the Business Day prior to the day of the proposed Borrowing by the Borrower to the Liquidity Provider. Upon satisfaction of the conditions precedent set forth in Section 4.2 with respect to a requested Borrowing, the Liquidity Provider shall, before 12:00 Noon (New York City time) on the date of such Borrowing or on such later Business Day specified by the Borrower in such Notice of Borrowing, make available to the Borrower, in U.S. dollars and in immediately available funds, the amount of such Borrowing to be paid to the Borrower in accordance with its payment instructions. If a Notice of Borrowing is delivered by the Borrower in respect of any Borrowing after 12:00 Noon (New York City time) on a Business Day, the Liquidity Provider shall, before 12:00 Noon (New York City time) on the second Business Day next following the day of receipt of such Notice of Borrowing or on such later Business Day specified by the Borrower in such Notice of Borrowing, make available to the Borrower, in U.S. dollars and in immediately available funds, the amount of such Borrowing to be paid to the Borrower in accordance with its payment instructions. Payments of proceeds of a Borrowing shall be made by wire transfer of immediately available funds to the Borrower in accordance with such wire transfer instructions as the Borrower shall furnish from time to time to the Liquidity Provider for such purpose. Each Notice of Borrowing shall be irrevocable and binding on the Borrower. (e) Upon the making of any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower's payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other person (including the holder of any Class B Certificate or the Class B Trustee) who makes to the Class B Trustee or the Borrower a demand for payment with respect to any Class B Certificate. By paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested. Section 2.3 Fees. (a) The Borrower agrees to pay to the Liquidity Provider a fee equal to 0.25% of the Commitment (as in effect on the Effective Date). Such fee shall be payable on the Effective Date. (b) The Borrower shall pay, or shall cause to be paid, to the Liquidity Provider, a fee equal to 0.40% per annum on the average Available Commitment from the Effective Date to the 7 11 earlier of the date on which a Downgrade Advance is made and the Termination Date. Such fee shall be payable in arrears on each Regular Distribution Date. Nothing contained in this Section 2.3 shall require the Borrower to pay any amount under this Section 2.3 other than to the extent the Borrower shall have funds available therefor. Section 2.4 Reduction or Termination of the Commitment. (a) Automatic Reductions. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance of the Class B Certificates or otherwise, the Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower). The Borrower shall give notice of any such automatic reduction of the Commitment (substantially in the form of Annex IV hereto) to the Liquidity Provider (with a copy to America West) within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Commitment. (b) Termination. Upon the making of any Downgrade Advance or Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to request any further Borrowing hereunder. Section 2.5 Repayments of Interest Advances or the Final Advance. Subject to Sections 2.7 and 2.9, the Borrower hereby agrees to pay, or to cause to be paid, to the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance or the Final Advance, an amount equal to (a) the amount of such Interest Advance or the Final Advance (any such Interest Advance or the Final Advance, until repaid, is referred to herein as an "Unpaid Advance"), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.7. Subject to Sections 2.6, 2.7 and 2.9, unless otherwise waived by the Liquidity Provider, the Borrower shall be obligated, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to repay the Liquidity Provider for all Interest Advances and Final Advances on the same day as made and all Applied Downgrade Advances on the same day they became Applied Downgrade Advances. The Borrower and the Liquidity Provider agree that the repayment in full of each Interest Advance and the Final Advance on the date such Interest Advance or the Final Advance is made and each Applied Downgrade Advance on the date it becomes an Applied Downgrade Advance is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider. 8 12 Section 2.6 Repayments of Downgrade Advances. (a) Amounts advanced hereunder in respect of a Downgrade Advance shall be deposited in the Class B Cash Collateral Account, and invested and withdrawn from the Class B Cash Collateral Account, as set forth in Sections 3.6(c), (e) and (f) of the Intercreditor Agreement. The Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Downgrade Advance, interest on the principal amount of any such Downgrade Advance as provided in Section 3.7. Immediately upon the withdrawal of any amounts from the Class B Cash Collateral Account on account of a reduction in the Required Amount, the Borrower shall repay the Downgrade Advance in a principal amount equal to the amount of such reduction, plus interest on the principal amount repaid as provided in Section 3.7. (b) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.6(e) of the Intercreditor Agreement, and prior to the effectiveness of any Replacement Liquidity Facility, the Borrower agrees that all amounts owing to the Liquidity Provider shall be repaid in full, whether from advances made by the Replacement Liquidity Provider, from amounts remaining on deposit in the Class B Cash Collateral Account after giving effect to any application of funds therefrom to any payment of interest on the Class B Certificates on the date of such replacement, or otherwise. Section 2.7 Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for payment or repayment to the Liquidity Provider of any amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so paid to the Liquidity Provider shall be applied by the Liquidity Provider in the order of priority required by the applicable provisions of Articles II and III of the Intercreditor Agreement. Section 2.8 Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided, however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances. 9 13 Section 2.9 Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement shall be made only from amounts received by it that constitute Scheduled Payments or Special Payments and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts to the extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except as expressly provided in this Agreement, the Intercreditor Agreement or any Refunding Agreement. Amounts on deposit in the Class B Cash Collateral Account shall be available to make payments only to the extent and for the purposes expressly contemplated in Section 3.6(f) of the Intercreditor Agreement. ARTICLE III OBLIGATIONS OF THE BORROWER Section 3.1 Increased Costs. If the Liquidity Provider shall determine that (a) any change in any law or regulation or in the interpretation thereof by any court or administrative or governmental authority charged with the administration thereof or in the compliance by the Liquidity Provider (or its head office) with any applicable direction, request or requirement (whether or not having the force of law) of any central bank or competent governmental or other authority shall either (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets held by, or deposits in or for the account of, or loans made by, the Liquidity Provider, or (ii) impose on the Liquidity Provider any other condition regarding this Agreement or any Advance, or (iii) change the basis of taxation of any amounts payable to the Liquidity Provider (other than Taxes imposed on the overall net or gross income of the Liquidity Provider) and (b) the result of any event referred to in the preceding clause (i), (ii) or (iii) shall be to increase the cost to the Liquidity Provider of issuing or maintaining its commitment or funding or maintaining Advances (which increase in cost shall be determined by the Liquidity Provider's reasonable allocations of the aggregate of such cost increases resulting from such event), then, no later than 30 days after demand by the Liquidity Provider, the Borrower shall pay, or cause to be paid, to the Liquidity Provider, from time to time as specified by the Liquidity Provider, additional amounts which shall be sufficient to compensate the Liquidity Provider for such increased cost. A certificate as to such increased cost incurred by the Liquidity Provider as a result of any event mentioned in clause (i), (ii) or (iii) above, prepared 10 14 in reasonable detail and submitted by the Liquidity Provider to the Borrower, shall be conclusive, absent manifest error, as to the amount thereof. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section 3.1 that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous in any material respect to the Liquidity Provider. Section 3.2 Capital Adequacy. If the Liquidity Provider shall determine that the adoption after the date hereof of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change after the date hereof in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance after the date hereof by the Liquidity Provider (or its head office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, is generally applicable to all banks domiciled in Belgium with branches in the United States and not related to the financial condition of the Liquidity Provider and has the effect of reducing the rate of return on the Liquidity Provider's capital as a consequence of issuing or maintaining its commitment hereunder or its funding or maintaining Advances to a level below that which the Liquidity Provider could have achieved but for such adoption, change or compliance (taking into consideration the Liquidity Provider's policies with respect to capital adequacy) by an amount deemed by the Liquidity Provider to be material, then, no later than 30 days after demand by the Liquidity Provider, the Borrower shall pay to the Liquidity Provider, from time to time as specified by the Liquidity Provider, additional amounts which shall be sufficient to compensate the Liquidity Provider for such reduction in respect of issuing or maintaining its commitment hereunder or its funding or maintaining Advances. A certificate as to such additional amount describing the event which has the effect of reducing the rate of return on the Liquidity Provider's capital, prepared in reasonable detail and submitted by the Liquidity Provider to the Borrower, shall be conclusive, absent manifest error, as to the amount thereof. The Liquidity Provider further agrees that no amounts shall be payable under this Section 3.2 unless the Liquidity Provider is charging its other borrowers with whom it has agreements similar to this agreement the amounts that are payable to the Liquidity Provider under this Section 3.2. 11 15 The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section 3.2 that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous in any material respect to the Liquidity Provider. Section 3.3 Payments Free of Deductions. All payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed, excluding any Taxes imposed on the overall net income of the Liquidity Provider and excluding United States federal income tax withholding to the extent such withholding is, or would be, actually imposed upon payments to the Liquidity Provider as of the date of this Agreement (such non-excluded taxes being referred to herein, collectively, as "Non-Excluded Taxes" and, individually, as a "Non-Excluded Tax"). If any Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, the amounts so payable to the Liquidity Provider shall be increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes and taxes imposed on the receipt of such increase) interest or any other such amounts payable under this Agreement at the rates or in the amounts specified in this Agreement. Whenever any Non-Excluded Tax is payable by the Borrower, promptly thereafter the Borrower shall send the Liquidity Provider certified copies of tax receipts evidencing such payment by the Borrower. The Liquidity Provider agrees to provide to the Borrower on or prior to the Effective Date, and from time to time thereafter prior to the expiration of the effectiveness of and promptly upon the occurrence of any event requiring a change in the most recent form previously delivered by it (and prior to the immediately following due date of any payment by the Borrower hereunder), to the extent that the Liquidity Provider is legally entitled to do so, two original Internal Revenue Service Form 1001 or 4224, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is completely exempt from United States withholding tax on payments pursuant to this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section 3.3 that may thereafter accrue and would not, in the reasonable judgment of the Liquidity 12 16 Provider, be otherwise disadvantageous in any material respect to the Liquidity Provider. Section 3.4 Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America, to the Liquidity Provider in immediately available funds, by wire transfer to The Bank of New York, One Wall Street, New York, NY 10286, ABA No. 021-000-018, for the account of Kredietbank New York, Account No. 802-3015618 (referencing America West Airlines Liquidity Facility). Section 3.5 Computations. All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of (x) interest based on the LIBOR Rate and (y) fees payable to the Liquidity Provider, shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. Section 3.6 Payment on Non-Business Days. Whenever any payment to be made hereunder (other than a payment on LIBOR Advances) becomes due and payable on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and interest thereon shall be payable at the then applicable rate during such extension. If any payment on a LIBOR Advance becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. Section 3.7 Interest. (a) The Borrower shall pay, or shall cause to be paid, interest on (i) the unpaid principal amount of each Advance from and including the date of such Advance to but excluding the date such principal amount shall be paid in full and (ii) any other amount due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate for such Advance for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest 13 17 rate as set forth in this Section 3.7 shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.7 below the maximum rate permitted by applicable law until the total amount of interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.7 had at all times been in effect. Nothing contained in this Section 3.7 shall require the Borrower to pay any amount under this Section 3.7 other than to the extent the Borrower shall have funds available therefor. (b) Each Advance will be either a Base Rate Advance or a LIBOR Advance as provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its borrowing to (but excluding) the third Business Day following the Liquidity Provider's receipt of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance; provided that the Final Advance shall, until repaid in full, be a Base Rate Advance and the Borrower may not convert the Final Advance into a LIBOR Advance. (c) Each LIBOR Advance shall bear interest during each Interest Period at a per annum rate equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid). (d) Each Base Rate Advance shall bear interest at a per annum rate equal to the Base Rate plus the Applicable Margin for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of interest accrued on the amount of principal repaid). (e) Each amount not paid when due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by applicable law, installments of interest on Advances) shall bear interest at the Base Rate. (f) Each change in the Base Rate shall become effective immediately. Section 3.8 Replacement of Borrower.

Section 3.10 Illegality. Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the Liquidity Provider (or its Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the last Interest Period to expire before the effective date of any such change or request. In the event any change of the nature described in the preceding sentence shall make it unlawful or impossible for the Liquidity Provider (or its Lending Office) to maintain or fund its Base Rate Advances, the Liquidity Provider shall have the right to cause a Replacement Liquidity Facility to be substituted for this Agreement, subject to (i) the satisfaction of the conditions precedent to the effectiveness of, and the other provisions regarding, a Replacement Liquidity Facility set forth in Section 3.6(e) of the Intercreditor Agreement and (ii) such Replacement Liquidity Facility and Replacement Liquidity Provider being reasonably acceptable to America West.

No such assignment shall release the Liquidity Provider from its obligations hereunder. Section 7.9 Severability. Any provision of this Agreement which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or nonauthorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.
