(c) A Downgrade Advance shall be made in a single Borrowing upon the occurrence of a Downgrade Event (as provided for in Section 3.5(c) of the Intercreditor Agreement) unless a Replacement Liquidity Facility to replace this Agreement shall have been previously delivered to the Borrower in accordance with Section 3.5(c), by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex III attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used solely to fund the Class B Cash Collateral Account in accordance with said Section 3.5(c) and Section 3.5(f) of the Intercreditor Agreement.

Each Notice of Borrowing shall be effective upon delivery of a copy thereof to the Liquidity Provider’s office at the address specified in Section 7.02. If a Notice of Borrowing is delivered by the Borrower in respect of any Borrowing no later than 1:00 p.m. (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and immediately available funds, before 4:00 p.m. (New York City time) on such Business Day or on such later Business Day specified in such Notice of Borrowing. If a Notice of Borrowing is delivered by the Borrower in respect of any Borrowing on a day that is not a Business Day or after 1:00 p.m. (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and in immediately available funds, before 12:00 Noon (New York City time) on the first 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. 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.

[Revolving Credit Agreement (2007-1B)]

(f) 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. If the Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c), (d) or (g) hereof to fund the Class B Cash Collateral Account, the Liquidity Provider shall have no interest in or rights to the Class B Cash Collateral Account, the funds constituting such Advance or any other amounts from time to time on deposit in the Class B Cash Collateral Account; provided that the foregoing shall not affect or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.5(e) or (f) of the Intercreditor Agreement, and provided further, that the foregoing shall not affect or impair the rights of the Liquidity Provider to provide written instructions with respect to the investment and reinvestment of amounts in the Cash Collateral Accounts to the extent provided in Section 2.2(b) of the Intercreditor Agreement. 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.

(g) A “Special Termination Advance” shall be made in a single Borrowing upon the receipt by the Borrower of a Special Termination Notice from the Liquidity Provider pursuant to Section 6.01(b), by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex VII, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used solely to fund the Class B Cash Collateral Account (in accordance with Section 3.5(f) and Section 3.5(k) of the Intercreditor Agreement).

The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment.

(b) Termination. Upon the making of any Provider Advance, or the Special Termination Advance, or the making of or conversion to a 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.

[Revolving Credit Agreement (2007-1B)]

Section 2.05 Repayments of Interest Advances , the Special Termination Advance or the Final Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), 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, the Special Termination Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is referred to herein as an “Unpaid Advance”) (if multiple Interest Advances are outstanding any such repayment to be applied in the order in which such Interest Advances have been made, starting with the earliest), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which shall not have been repaid in accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed Interest Advances have reduced the Maximum Available Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or an Applied Non-Extension Advance, as the case may be, for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for the purposes of Section 2.06(b)); provided, further, that amounts in respect of a Special Termination Advance withdrawn from the Class B Cash Collateral Account for the purpose of paying interest on the Class B Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being an “Applied Special Termination Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; and provided, further, that if, following the making of a Special Termination Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01(a), such Special Termination Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and as an Applied Special Termination Advance for purposes of Section 2.6(c) of the Intercreditor Agreement. The Borrower and the Liquidity Provider agree that the repayment in full of each Interest Advance, Special Termination Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider.

Section 2.06 Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider Advance shall be deposited in the Class B Cash Collateral Account, invested and withdrawn from the Class B Cash Collateral Account as set forth in Sections 3.5(c), (d), (e) and (f) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09, 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 Provider Advance, interest on the principal amount of any such Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class B Cash Collateral Account for the purpose of paying interest on the Class B Certificates in accordance with Section 3.5(f) of

[Revolving Credit Agreement (2007-1B)]

the Intercreditor Agreement (the amount of any such withdrawal being (y) in the case of a Downgrade Advance, an “Applied Downgrade Advance” and (z) in the case of a Non-Extension Advance, an “Applied Non-Extension Advance” and, together with an Applied Downgrade Advance, an “Applied Provider Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the dates on which such interest is payable; provided further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01 hereof, such Provider Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and as an Applied Downgrade Advance or Applied Non-Extension Advance, as the case may be, for the purposes of Section 2.6(c) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09 hereof, 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 to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to the amount of such reduction, plus interest on the principal amount prepaid as provided in Section 3.07 hereof.

(b) At any time when an Applied Provider Advance (or any portion thereof) is outstanding, upon the deposit in the Class B Cash Collateral Account of any amount pursuant to clause “fourth” of Section 3.2 of the Intercreditor Agreement (any such amount being a “Replenishment Amount”) for the purpose of replenishing or increasing the balance thereof up to the amount of the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances (and of Provider Advances treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount (if multiple Applied Provider Advances are outstanding, such Replenishment Amount to be applied in the order in which such Applied Provider Advances have been made, starting with the earliest) and (ii) the aggregate outstanding principal amount of all Unapplied Provider Advances shall be automatically increased by the amount of such Replenishment Amount.

(c) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.5(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class B Cash Collateral Account after giving effect to any Applied Provider Advance or Applied Special Termination Advance on the date of such replacement shall be reimbursed to the replaced Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the replaced Liquidity Provider all amounts owing to it hereunder.

Section 2.07 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 3.5(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so paid to, and not required to be returned by, the Liquidity Provider shall be applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the Intercreditor Agreement and shall discharge in full the corresponding obligations of the Borrower hereunder (or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate).

[Revolving Credit Agreement (2007-1B)]

Section 2.08 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.

Section 2.09 Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement, including, without limitation, Sections 7.05 and 7.07, shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under the Fee Letter and Section 7.1 of the Participation Agreements 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 in respect of payments to be made by the Borrower hereunder 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 Participation Agreement. Amounts on deposit in the Class B Cash Collateral Account shall be available to the Borrower to make payments under this Agreement only to the extent and for the purposes expressly contemplated in Section 3.5(f) of the Intercreditor Agreement.

Section 2.10 Extension of the Expiry Date; Non-Extension Advance. If the Liquidity Provider advises the Borrower before the 25th day prior to the immediately following anniversary date of the Closing Date (the “Notice Date”) that its obligation to make Advances hereunder shall not be so extended beyond such anniversary date (and if the Liquidity Provider shall not have been replaced in accordance with Section 3.5(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after the Notice Date (but prior to such anniversary date) to request a Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.5(d) of the Intercreditor Agreement.

ARTICLE III

OBLIGATIONS OF THE BORROWER

Section 3.01 Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such amounts as may be necessary to compensate the Liquidity Provider for any increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any Advances hereunder or its obligation to make any such Advances hereunder, or any reduction in any amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign

[Revolving Credit Agreement (2007-1B)]

laws or regulations (including Regulation D of the Board of Governors of the Federal Reserve System), or the adoption or making after the date of this Agreement of any interpretations, directives, or requirements applying to a class of banks including the Liquidity Provider under any U.S. federal, state, municipal, or any foreign laws or regulations (whether or not having the force of law) by any court, central bank or monetary authority charged with the interpretation or administration thereof (a “Regulatory Change”), which: (1) changes the basis of taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances or such obligation (other than with respect to Excluded Taxes or Indemnified Taxes); or (2) imposes or modifies any reserve, special deposit, compulsory loan or similar requirements relating to any extensions of credit or other assets of, or any deposits with other liabilities of, the Liquidity Provider (including any such Advances or such obligation or any deposits referred to in the definition of LIBOR Rate or related definitions). The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policies and applicable 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 that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section; provided, that if the Liquidity Provider fails to give such notice within 180 days after it obtains such knowledge, the Liquidity Provider shall, with respect to any costs resulting from such event, only be entitled to payment under this Section 3.01 for costs incurred from and after the date 180 days prior to the date the Liquidity Provider does give such notice. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section.

Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination Agent agree that (i) the initial Liquidity Provider and (ii) any permitted assignee or participant of the initial Liquidity Provider which is not a bank, shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof).

Section 3.02 Capital Adequacy. If (1) the adoption, after the date hereof, of any applicable governmental law, rule or regulation regarding capital adequacy, (2) any change, after the date hereof, in the interpretation or administration of any such law, rule or regulation by any central bank or other governmental authority charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider with any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in clause (2), has the effect of requiring an increase in the amount of capital required to be maintained by the Liquidity

[Revolving Credit Agreement (2007-1B)]

Provider or any corporation controlling the Liquidity Provider and such increase is based upon the Liquidity Provider’s obligations hereunder (including funded obligations) and other similar obligations, the Borrower shall, subject to the provisions of the next paragraph, pay to the Liquidity Provider from time to time such additional amount or amounts as are necessary to compensate the Liquidity Provider for such portion of such increase as shall be reasonably allocable to the Liquidity Provider’s obligations to the Borrower hereunder.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section; provided, that if the Liquidity Provider fails to give such notice within 180 days after it obtains such knowledge, the Liquidity Provider shall, with respect to any costs resulting from such event, only be entitled to payment under this Section 3.02 for costs incurred from and after the date 180 days prior to the date the Liquidity Provider does give such notice. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital required to be maintained by the Liquidity Provider and of the amount allocable to the Liquidity Provider’s obligations to the Borrower hereunder shall be prima facie evidence of the amounts owed under this Section, absent manifest error.

Section 3.03 Payments Free of Deductions. (a) Unless required by applicable law, 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 Taxes of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed. If any Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, (i) the Borrower shall within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) in the case of Taxes, other than Excluded Taxes (such non-excluded Taxes being referred to herein, collectively, as “Indemnified Taxes” and each, individually, as a “Indemnified Tax”), 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 Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts specified in 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 such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower

[Revolving Credit Agreement (2007-1B)]

such original Internal Revenue Service Forms (including X-0XXX, X-0XXX or W-9), as appropriate with respect to Liquidity Provider, or any successor or other form prescribed by the Internal Revenue Service, certifying as to any available exemption from or reduction in the rate of United States withholding tax on payments pursuant to this Agreement. Within 30 days after the date of each payment hereunder, the Borrower shall furnish to the Liquidity Provider the original or a certified copy of (or other documentary evidence of) the payment of the Indemnified Taxes applicable to such payment.

(b) Unless required by applicable law, all payments (including, without limitation, Advances) made by the Liquidity Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes) will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to the Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment.

(c) If any exemption from, or reduction in the rate of, any Taxes is reasonably available to the Borrower to establish that payments under this Agreement are exempt from (or entitled to a reduced rate of) tax, the Borrower shall deliver to the Liquidity Provider such form or forms and such other evidence of the eligibility of the Borrower for such exemption or reduction as the Liquidity Provider may reasonably identify to the Borrower as being required as a condition to exemption from, or reduction in the rate of, any Taxes.

Section 3.04 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 account of Xxxxxx Xxxxxxx Senior Funding, Inc. at Citibank, N.A. ABA No. 000000000, Account No. 000-00-000, Reference: United Air Lines 2007-1 EETC, or to such other account as the Liquidity Provider may from time to time direct the Borrower.

Section 3.05 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 interest based on the LIBOR Rate 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 3.06 Payment on Non-Business Days. Whenever any payment to be made hereunder to the Liquidity Provider shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day (and if so made, shall be deemed to have been made when due).

[Revolving Credit Agreement (2007-1B)]

Section 3.07 Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause to be paid, without duplication, interest on (i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, from and including the date on which the amount thereof was withdrawn from the Class B Cash Collateral Account to pay interest on the Class B Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, the date on which the Class B Cash Collateral Account is fully replenished in respect of such Advance) 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) that 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 (as defined below) for such Advance or such other amount, as the case may be, as in effect 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 rate as set forth in this Section 3.07 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 3.07 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 3.07 had at all times been in effect.

(b) Except as provided in clause (e) below, 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.

(c) Each LIBOR Advance shall bear interest during each Interest Period at a rate per annum 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 rate per annum 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 outstanding Unapplied Non-Extension Advance, Unapplied Downgrade Advance and Unapplied Special Termination Advance shall bear interest in an amount equal to the Investment Earnings on amounts on deposit in the Class B Cash Collateral Account plus the Applicable Margin for such Unapplied Non-Extension Advance, Unapplied Downgrade Advance

[Revolving Credit Agreement (2007-1B)]

or Unapplied Special Termination Advance, as applicable, on the amount of such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance from time to time, payable in arrears on each Regular Distribution Date.

(f) 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 but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% per annum until paid.

(g) Each change in the Base Rate shall become effective immediately. The rates of interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the “Applicable Liquidity Rate”.

Section 3.08 Replacement of Borrower. From time to time and subject to the successor Borrower’s meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent in substantially the form of Annex VI attached hereto (a “Notice of Replacement Subordination Agent”) delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted for the Borrower for all purposes hereunder.

Section 3.09 Funding Loss Indemnification. The Borrower shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of:

(1) Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such Advance; or

(2) Any failure by the Borrower to borrow a LIBOR Advance on the date for borrowing specified in the relevant notice under Section 2.02.

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. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policies and

[Revolving Credit Agreement (2007-1B)]

applicable legal and regulatory restrictions) to change the jurisdiction of its Lending Office if making such change would avoid or cure the aforesaid illegality and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

Section 7.04 Further Assurances.

[Revolving Credit Agreement (2007-1B)]

resulting from, or arising out of or in connection with any action, suit or proceeding by any third party against such Liquidity Indemnitee and relating to this Agreement, the Fee Letter, the Intercreditor Agreement or any Participation Agreement; provided, however, that the Borrower shall not be required to indemnify, protect, defend and hold harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity Indemnitee to the extent such Expense is (i) attributable to the gross negligence or willful misconduct of such Liquidity Indemnitee or any other Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, (iii) attributable to the failure by such Liquidity Indemnitee or any other Liquidity Indemnitee to perform or observe any agreement, covenant or condition on its part to be performed or observed in this Agreement, the Intercreditor Agreement, the Fee Letter applicable to this Agreement or any other Operative Agreement to which it is a party; or (iv) a Tax. The indemnities contained in Section 7.1 of the Participation Agreements, and the provisions of Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall survive the termination of this Agreement.

Section 7.06 Liability of the Liquidity Provider. (a) Neither the Liquidity Provider nor any of its officers, employees, directors or Affiliates shall be liable or responsible for: (i) the use which may be made of the Advances or any acts or omissions of the Borrower or any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; or (iii) the making of Advances by the Liquidity Provider against delivery of a Notice of Borrowing and other documents which do not comply with the terms hereof; provided, however, that the Borrower shall have a claim against the Liquidity Provider, and the Liquidity Provider shall be liable to the Borrower, to the extent of any damages suffered by the Borrower which were the result of (A) the Liquidity Provider’s willful misconduct or negligence in determining whether documents presented hereunder comply with the terms hereof, or (B) any breach by the Liquidity Provider of any of the terms of this Agreement or the Intercreditor Agreement, including, but not limited to, the Liquidity Provider’s failure to make lawful payment hereunder after the delivery to it by the Borrower of a Notice of Borrowing strictly complying with the terms and conditions hereof. In no event, however, shall the Liquidity Provider be liable on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings).

(b) Neither the Liquidity Provider nor any of its officers, employees, directors or Affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or gross negligence (in which event the extent of the Liquidity Provider’s potential liability to the Borrower shall be limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing.

Section 7.07 Costs, Expenses and Taxes. The Borrower agrees to pay, or cause to be paid (A) on the Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket costs and expenses (including, without limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and

[Revolving Credit Agreement (2007-1B)]

recording of this Agreement, any other Operative Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses (including reasonable counsel fees and expenses) of the Liquidity Provider in connection with (i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such other documents which may be delivered in connection herewith or therewith (whether or not the same shall become effective) or any waiver or consent thereunder (whether or not the same shall become effective) or (iii) any action or proceeding relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting the application of funds in the Class B Cash Collateral Account. In addition, the Borrower shall pay any and all recording, stamp and other similar taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to hold the Liquidity Provider harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees.

Section 7.08 Binding Effect; Participations. (a) This Agreement shall be binding upon and inure to the benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08 and in Section 3.5(l) of the Intercreditor Agreement) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the other Operative Agreements to such Persons (other than United and its Affiliates) as the Liquidity Provider may in its sole discretion select, subject to the requirements of Section 7.08(b). No such granting of participations by the Liquidity Provider, however, will relieve the Liquidity Provider of its obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider’s source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative Agreements to determinations, reserve and capital adequacy requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03 and the like as they pertain to the Liquidity Provider shall be deemed also to include those of each of its participants that are banks (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the participant, had held the interest participated).

(b) If, pursuant to subsection (a) above, the Liquidity Provider sells any participation in this Agreement to any bank or other entity (each, a “Transferee”), the Transferee shall not be entitled to receive any greater payment under Section 3.03 than the Liquidity Provider would have been entitled to receive with respect to the participation sold to such Transferee. A Transferee shall not be entitled to the benefits of Section 3.03 unless the Borrower is notified of

[Revolving Credit Agreement (2007-1B)]

the participation sold to such Transferee and such Transferee agrees, for the benefit of the Borrower, to comply with the certification requirements of Section 3.03 as though it were the Liquidity Provider. Unless the Borrower has received forms or other documents reasonably satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

(c) Notwithstanding the other provisions of this Section 7.08, the Liquidity Provider may assign and pledge all or any portion of the Advances owing to it to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank, provided that any payment in respect of such assigned Advances made by the Borrower to the Liquidity Provider in accordance with the terms of this Agreement shall satisfy the Borrower’s obligations hereunder in respect of such assigned Advance to the extent of such payment. No such assignment shall release the Liquidity Provider from its obligations hereunder.

Section 7.09 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 non-authorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

Section 7.10 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW THEREOF (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW)).

Section 7.11 Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto hereby irrevocably and unconditionally:

(i) submits for itself and its property in any legal action or proceeding relating to this Agreement or any other Operative Agreement, or for recognition and enforcement of any judgment in respect hereof or thereof, to the nonexclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and the appellate courts from any thereof;

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider shall have been notified pursuant thereto; and

[Revolving Credit Agreement (2007-1B)]

(iv) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to xxx in any other jurisdiction.

(b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. The Borrower and the Liquidity Provider each warrant and represent that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

Section 7.12 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 7.13 Entirety. This Agreement, the Intercreditor Agreement and the other Operative Agreements to which the Liquidity Provider is a party constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements of such parties.

Section 7.14 Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 7.15 LIQUIDITY PROVIDER’S OBLIGATION TO MAKE ADVANCES. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE OBLIGATIONS OF THE LIQUIDITY PROVIDER TO MAKE ADVANCES HEREUNDER, AND THE BORROWER’S RIGHTS TO DELIVER NOTICES OF BORROWING REQUESTING THE MAKING OF ADVANCES HEREUNDER, SHALL BE UNCONDITIONAL AND IRREVOCABLE, AND SHALL BE PAID OR PERFORMED, IN EACH CASE STRICTLY IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT.

Section 7.16 Patriot Act. The Liquidity Provider hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), the Liquidity Provider is required to obtain, verify and record, and the Borrower shall provide to the Liquidity Provider upon request, information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow the Liquidity Provider to identify the Borrower in accordance with the Act.
