In connection with any assignment pursuant to Section 9.2, the Administrative Agent shall maintain a copy of each Assignment and Acceptance delivered to and accepted by it and shall record the names and addresses of the Lenders and principal amount of the Loan owing to each Lender from time to time. Solely for purposes of this Section 2.3(e), the Administrative Agent shall be the Borrower’s agent for purposes of establishing and maintaining the Register.

Section 2.6 Interest.

(a) Rate of Interest. Except as otherwise provided in Section 2.6(c) and Section 2.9, the Borrower shall pay interest (i) in the case of the Loan, at the Index Rate plus the Applicable Index Margin per annum or, at the election (or deemed election) of the Borrower, the applicable LIBOR Rate plus the Applicable LIBOR Margin per annum and (ii) in the case of all other Obligations that are due and payable, at the Index Rate plus the Applicable Index Margin per annum.

(b) Interest Payments. Interest accrued on the Loan shall be payable to the Administrative Agent, for the ratable benefit of the Lenders, in arrears on each Interest Payment Date, upon the payment or prepayment thereof in whole or in part, and, if not previously paid in full, at maturity (whether by acceleration or otherwise). Interest on the Loan shall be calculated on the basis of a year of 360 days (or in the case of interest calculated based upon the Index Rate, a 365/366 day year) and actual number of days elapsed.

(c) Default Interest. Notwithstanding the rate of interest specified in Section 2.6(a), effective immediately upon (i) the occurrence of any Event of Default under Sections 7.1(a) (with respect to principal due on the Maturity Date and scheduled interest payments only), 7.1(f) or 7.1(g) or (ii) the delivery of a notice by the Administrative Agent or the Requisite Lenders to the Borrower declaring default interest to be payable during the continuance of any other Event of Default and, in each case, for as long as such Event of Default shall be continuing, the principal balance of all Obligations (including any Obligation that bears interest by reference to the rate applicable to any other Obligation) then due and payable shall bear interest at a rate that is 2% per annum in excess of the interest rate applicable to such Obligations from time to time, payable on demand or, in the absence of demand, on the date that would otherwise be applicable.

(d) Conversion/Continuation. So long as no Event of Default has occurred and is continuing, the Borrower shall have the option to (i) convert at any time all or any part of the outstanding Loans from Index Rate Loans to LIBOR Loans, (ii) convert any LIBOR Loan to an Index Rate Loan,

subject to payment of LIBOR breakage costs in accordance with Section 2.9(d) if such conversion is made prior to the expiration of the LIBOR Period applicable thereto, or (iii) continue all or any portion of any Loan as a LIBOR Loan upon the expiration of the applicable LIBOR Period, and the succeeding LIBOR Period of that continued Loan shall commence on the first day after the last day of the LIBOR Period of the Loan to be continued. Any Loan or group of Loans having the same proposed LIBOR Period to be made or continued as, or converted into, a LIBOR Loan must be in a minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of such amount. Any such election must be made by 11:00 a.m. (New York time) on the third Business Day prior to (1) the date of any proposed Loan which is to bear interest at the LIBOR Rate, (2) the end of each LIBOR Period with respect to any LIBOR Loans to be continued as such, or (3) the date on which the Borrower wishes to convert any Index Rate Loan to a LIBOR Loan for a LIBOR Period designated by the Borrower in such election. If no election is received with respect to a LIBOR Loan by 11:00 a.m. (New York time) on the third Business Day prior to the end of the LIBOR Period with respect thereto (or if an Event of Default has occurred and is continuing), the Borrower shall be deemed to have elected to continue such Loan as a LIBOR Loan pursuant to clause (iii) above with the same duration LIBOR Period as the LIBOR Period applicable to the Loan being continued. In each case except in the case of a deemed election in accordance with the preceding sentence, the Borrower must make such election by notice to the Administrative Agent in writing, by telecopy or overnight courier and, in the case of any conversion or continuation, such election must be made pursuant to a written notice (a “Notice of Conversion/Continuation”) in the form of Exhibit L. No Loan may be made as or converted into a LIBOR Loan until after five (5) Business Days following the Closing Date (unless otherwise agreed by the Administrative Agent) and, until the earlier of ninety (90) days following the Closing Date and completion of primary syndication of the Loans as determined by the Administrative Agent, no Loan may be converted into or continued as a LIBOR Loan that has an interest period of more than one month.

Section 2.7 Fees.

(a) Agency Fees. The Borrower shall pay to the Administrative Agent and its Affiliates the fees described in the Commitment Letter.

(b) Fees Non-refundable. All fees paid under this Section 2.7 shall be non-refundable.

(c) Interest on Fees. If any fee or other amount payable by the Borrower hereunder is not paid when due, such overdue amount shall bear interest at a rate which is two percent (2.0%) per annum in excess of the then applicable interest rate on Index Rate Loans.

Section 2.8 Payments and Computations.

(a) Payments. The Borrower shall make each payment hereunder (including fees and expenses) not later than 12:00 noon (New York City time) on the day when due, in Dollars, to the Administrative Agent at the Collection Account, in immediately available funds without set-off, defense, recoupment or counterclaim. All payments in respect of any Obligations shall at all times be made to the Administrative Agent, whether or not a demand shall have been made. The Administrative Agent will promptly cause all such payments received by it to be distributed to the Person entitled thereto in accordance with the priorities of payment set forth below in Section 2.8(d) or (e), or both, as applicable. Payments received by the Administrative Agent after 12:00 noon (New York City time) shall be deemed to be received on the next Business Day.

(b) Computation. Each determination by the Administrative Agent of an interest rate and fees hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Payments on Business Days. Except as otherwise expressly provided herein, whenever any payment hereunder 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 such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be.

(d) Application of Payments — No Event of Default. So long as no Event of Default under any of clauses (a) (including any failure to pay all amounts hereunder upon acceleration as a result of any other Event of Default), (f) or (g) of Section 7.1 has occurred and is continuing or would result therefrom, the Administrative Agent shall apply all payments in respect of any Obligations in the following order:

(i) first, to pay any fees then due and payable under Section 2.7(a) to the Administrative Agent;

(ii) second, to pay interest then due and payable in respect of the Loan to the Lenders on a pro rata basis;

(iii) third, to pay principal then due and payable on the Loan to the Lenders, on a pro rata basis; and

(iv) fourth, to pay any other Obligations then due and payable to the Administrative Agent and the Lenders, on a pro rata basis.

(e) Application of Payments After Event of Default. After the occurrence and during the continuance of an Event of Default under any of clauses (a) (including any failure to pay all amounts hereunder upon acceleration as a result of any other Event of Default), (f) or (g) of Section 7.1, the Administrative Agent shall apply all payments in respect of any Secured Obligations (including amounts received by the Administrative Agent upon the exercise of remedies under the Collateral Documents) in the following order:

(i) first, to pay Obligations in respect of any expenses, fees, indemnities or other sums (excluding principal and interest) owing hereunder then due to the Administrative Agent in its capacity as such;

(ii) second, to pay Obligations in respect of any expenses, fees, indemnities or other sums owing hereunder not referred to in clauses (iii) and (iv) below then due to the Lenders, on a pro rata basis;

(iii) third, to pay on a pro rata basis interest then due and payable in respect of the Loan to the Lenders;

(iv) fourth, to pay or prepay principal payments on the Loan to the Lenders and to pay amounts owing with respect to the Secured Hedging Contracts, on a pro rata basis; and

(v) fifth, to pay any other Secured Obligations then due and payable to the Secured Parties, on a pro rata basis.

(f) Funding Defaults. Unless the Borrower has notified the Administrative Agent, prior to the date any payment is required to be made by it to the Administrative Agent hereunder, that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a

corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then each Lender shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender to the date such amount is repaid to the Administrative Agent in immediately available funds (at the applicable Federal Funds Rate from time to time in effect for the first Business Day and thereafter, at the rate applicable to Index Rate Loans). A notice of the Administrative Agent to the Lenders with respect to any amount owing under this subsection (f) shall be conclusive, absent manifest error.

Section 2.9 Certain Provisions Governing the Loan.

(a) Interest Rate Unascertainable, Inadequate or Unfair. In the event that (i) the Administrative Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the LIBOR Rate is determined or (ii) the Requisite Lenders notify the Administrative Agent that the LIBOR Rate for any LIBOR Period will not adequately reflect the cost to the Lenders of making or maintaining the Loan for such LIBOR Period, the Administrative Agent shall promptly so notify the Borrower and the Lenders, whereupon the obligation of each Lender to make or to continue LIBOR Loans shall be suspended as provided in clause (e) below until the Administrative Agent shall notify the Borrower that the Requisite Lenders have determined that the circumstances causing such suspension no longer exist.

(b) Increased Costs. If at any time any Lender shall determine that as a result of the introduction of or any change after the date hereof in or in the interpretation of any law, treaty or governmental rule, regulation or order or the compliance by such Lender with any guideline, request or directive after the date hereof from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to such Lender of agreeing to make or making, funding, guaranteeing or maintaining any portion of the Loan (except in respect of Taxes), then the Borrower shall from time to time, within five (5) Business Days of a demand (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount thereof in reasonable detail) by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost; provided that no Lender shall be entitled to claim any such additional amount for amounts incurred more than six (6) months prior to the making of such demand. A certificate as to the amount of such increased cost, submitted to the Borrower (and the Administrative Agent) by such Lender shall be conclusive and binding for all purposes, absent manifest error. Each Lender shall promptly notify in writing the Borrower and the Administrative Agent of any event of which such Lender has knowledge, occurring after the date hereof, which would entitle such Lender to compensation pursuant to this Section 2.9(b) and will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender be otherwise disadvantageous to it.

(c) Illegality. If any Lender determines that the introduction of, or any change in or in the interpretation of, any Requirement of Law after the date of this Agreement shall make it unlawful, or any Governmental Authority shall assert that it is unlawful, for any Lender or its applicable lending office to make LIBOR Loans or to continue to fund or maintain LIBOR Loans, then, on notice thereof and demand therefor by such Lender to the Borrower through the Administrative Agent, the obligation of such Lender to make or to continue LIBOR Loans shall be suspended as provided in clause (e) below until such Lender shall, through the Administrative Agent, notify the Borrower that it has determined that it may lawfully make LIBOR Loans.

(d) Breakage Costs. In addition to all amounts required to be paid by the Borrower pursuant to Section 2.5, the Borrower shall compensate each Lender upon demand, for all losses, expenses and liabilities (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender or the termination of any other financial arrangement it may have entered into to fund or maintain or support such Lender’s portion of the Loan, but excluding Taxes) which that Lender may sustain (i) if for any reason any portion of the Loan is prepaid (including mandatorily pursuant to Section 2.5 or this Section 2.9) on a date which is not the last day of the applicable LIBOR Period or (ii) as a consequence of any failure by a Borrower to repay any portion of the Loan when required by the terms hereof. The Lender making demand for such compensation shall deliver to the Borrower (with a copy to the Administrative Agent) concurrently with such demand a written statement as to such losses, expenses and liabilities, and this statement shall be conclusive as to the amount of compensation due to that Lender absent manifest error, and such compensation shall be paid to the Administrative Agent for the account of such Lender.

(e) Effect of Suspension. If the obligation of any Lender to make or to continue LIBOR Loans is suspended, (i) the obligation of such Lender to convert Index Rate Loans into LIBOR Loans shall be suspended, (ii) such Lender shall make an Index Rate Loan at any time such Lender would otherwise be obligated to make a LIBOR Loan, (iii) the Borrower may revoke any pending Notice of Conversion/Continuation to make or continue any LIBOR Loan or to convert any Index Rate Loan into a LIBOR Rate Loan and (iv) each LIBOR Loan of such Lender shall automatically and immediately (or, in the case of any suspension pursuant to clause (a) above, on the last day of the current LIBOR Period thereof) be converted into an Index Rate Loan.

Section 2.10 Capital Adequacy. If at any time any Lender determines that (a) the adoption of or any change in or in the interpretation of any law, treaty or governmental rule, regulation or order after the date of this Agreement regarding capital adequacy, (b) compliance with any such law, treaty, rule, regulation, or order or (c) compliance with any guideline or request or directive from any central bank or other Governmental Authority or any accounting board or authority (whether or not a Governmental Authority) which is responsible for the establishment or interpretation of national or international accounting principles (in each case, whether or not having the force of law) shall have the effect of reducing the rate of return on such Lender’s (or any corporation controlling such Lender’s) capital as a consequence of its obligations hereunder (other than with respect to Taxes) to a level below that which such Lender or corporation could have achieved but for such adoption, change, compliance or interpretation, then, upon demand from time to time by such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall within five (5) Business Days of such demand pay to the Administrative Agent for the account of such Lender from time to time as specified by such Lender additional amounts sufficient to compensate such Lender for such reduction; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section 2.10 for any amounts incurred more than six (6) months prior to the date of such demand. A certificate as to such amounts submitted to the Borrower (and the Administrative Agent) by such Lender shall be conclusive and binding for all purposes absent manifest error. Each Lender shall promptly notify the Borrower and the Administrative Agent of any event of which such Lender or has knowledge, occurring after the date hereof, which would entitle such Lender to compensation pursuant to this Section 2.10 and will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to it. For the avoidance of doubt, any interpretation of Accounting Research Bulletin No. 51 by FASB (including Interpretation No. 46 – Consolidation of Variable Interest Entities) shall constitute an adoption, change, request or directive, and any implementation thereof shall be, subject to this Section 2.10.

Section 2.11 Taxes.

(a) No Withholding, etc. Except as otherwise provided in the next sentence and Section 9.2, any and all payments by the Obligors under each Loan Document shall be made free and clear of and without deduction for any and all Taxes, excluding (i) in the case of each Lender, each Participant and the Administrative Agent, Taxes measured by its net income and franchise Taxes, in each case if imposed on it as a result of such Person being organized under the laws of the jurisdiction imposing such Taxes or doing business in such jurisdiction unrelated to the transactions contemplated by any Loan Document, (ii) in the case of each Lender and each Participant, Taxes measured by its net income and franchise Taxes imposed on it by the jurisdiction in which its Lending Office is located or in which it booked its participation for tax accounting purposes, (iii) in the case of each Lender, each Participant and the Administrative Agent, Taxes imposed on it as a result of its failure to comply with its obligations under Section 2.11(f), Section 2.11(g) or Section 9.2, (iv) in the case of each Lender, each Participant and the Administrative Agent (A) that is a party hereto or Participant, as the case may be, on the Closing Date, United States federal withholding Taxes except to the extent imposed as a result of a change in applicable law, including income tax conventions, after the Closing Date and (B) that becomes a party hereto or Participant, as the case may be, after the Closing Date, United States federal withholding Taxes except to the extent imposed as a result of a change in applicable law, including income tax conventions, after the date of the Assignment and Acceptance pursuant to which it becomes a Lender or after the date such Person becomes a Participant, or the Administrative Agent, as applicable, and (v) Taxes imposed as a result of such Person’s gross negligence or willful misconduct (all such non-excluded Taxes being hereinafter referred to as “Indemnified Taxes”). If any Indemnified Taxes shall be required by law to be deducted from or in respect of any sum payable under any Loan Document to any Lender, or the Administrative Agent (1) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.11) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (2) the Obligors shall make such deductions, and (3) the Obligors shall pay the full amount deducted to the relevant taxing authority or other authority in accordance with applicable law.

(b) Other Taxes. In addition, the Obligors agree to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies of the United States or any political subdivision thereof or any applicable foreign jurisdiction which arise from any payment made under any Loan Document or from the execution, delivery or registration of, or otherwise with respect to, any Loan Document (collectively, “Other Taxes”) to the Administrative Agent for the account of the affected party.

(c) Tax Indemnity. The Obligors will indemnify each Lender and the Administrative Agent for the full amount of Indemnified Taxes or Other Taxes (including any Taxes imposed by any jurisdiction on amounts payable under this Section 2.11) paid by such Lender or the Administrative Agent (as the case may be) and any liability (including for penalties, interest and expenses) arising therefrom or with respect thereto, other than any liability, including for penalties, interest and expenses, arising from the gross negligence or willful misconduct of the Lender or the Administrative Agent, as the case may be. This indemnification shall be made to the Administrative Agent for account of the relevant Lender or the Administrative Agent, as the case may be, within 30 days from the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor (with a copy to the Administrative Agent if made by a Lender and accompanied by a statement setting forth the basis for such taxation and the calculation of the amount thereof in reasonable detail).

(d) Evidence of Payment. Within 30 days after the date of any payment of Indemnified Taxes or Other Taxes, the Obligors will furnish to the Administrative Agent the original or a certified copy of a receipt evidencing payment thereof or other documentation reasonably satisfactory to the Administrative Agent.

(e) Survival. Without prejudice to the survival of any other agreement of the Obligors hereunder, the agreements and obligations of the parties contained in this Section 2.11 shall survive the payment in full of the Obligations.

(f) Certain Withholding Tax Matters. Each Lender, each Participant and the Administrative Agent that is a Non-U.S. Person and that is entitled at such time to an exemption from United States withholding tax, or that is subject to such tax at a reduced rate under an applicable tax treaty, shall, on or prior to the Closing Date or on or prior to the date of the Assignment and Acceptance pursuant to which it becomes a Lender or on or prior to the date such Person becomes a Participant or the Administrative Agent, as applicable, and from time to time thereafter if requested by the Administrative Agent or the Borrower, provide the Administrative Agent and the Borrower with two completed copies of either IRS Form W-8BEN or W-8ECI or other applicable form, certificate or document prescribed by the IRS certifying as to such Non-U.S. Person’s entitlement to such exemption from United States withholding tax or reduced rate with respect to all payments to be made to such Non-U.S. Person under the Loan Documents. In addition, each Lender, each Participant and the Administrative Agent that is a Non-U.S. Person, as the case may be, shall deliver to the Borrower and the Administrative Agent, notice of any event (other than a change in applicable law, including income tax conventions) requiring a change in the most recent form previously delivered by such Person to the Borrower and the Administrative Agent. Each Lender, each Participant and the Administrative Agent (other than an entity treated as a corporation for U.S. federal income tax purposes) that is a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code shall deliver two duly signed and completed copies of IRS Form W-9 to the Administrative Agent and the Borrower, at the times and in the manner described above with respect to IRS Forms W-8. Unless the Administrative Agent and the Borrower have received forms or other documents satisfactory to them indicating that payments under the Loan Documents are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, the Administrative Agent or the Borrower shall, notwithstanding the provisions of Section 2.11(a) and (c) and without impairing any obligation of the Obligors under this Section 2.11 with respect to such tax, withhold such United States withholding taxes from such payments at the appropriate rate; provided that if such Person is a Lender, Participant, or Administrative Agent and shall have satisfied the requirement of this Section 2.11(f) on the date it became a Lender, Participant, or Administrative Agent, nothing in this Section 2.11(f) shall relieve the Obligors of their obligation to pay any amounts pursuant to this Section 2.11 in the event that, as a result of any change in any applicable law, treaty or governmental rule, regulation or order, or any change in governmental interpretation, administration or application thereof, such Lender, Participant, or Administrative Agent is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing that it is not subject to withholding or is subject to withholding at a reduced rate. The obligation of the Obligors under this Section 2.11 shall survive the repayment of all other Obligations hereunder and the resignation of the Administrative Agent.

(g) Mitigation. Any Lender claiming any additional amounts payable pursuant to this Section 2.11 shall use its reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts which would be payable or may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

Section 2.12 Substitution of Lenders.

(a) Substitution Right. In the event that any Lender (an “Affected Lender”) (i) makes a claim under Section 2.9(b) or Section 2.10, (ii) notifies the Borrower pursuant to Section 2.9(c) that it becomes illegal for such Lender to continue to fund or make any LIBOR Loans, or (iii) is entitled

to (and does not waive) any increased payment attributable to Indemnified Taxes or makes a claim for payment pursuant to Section 2.11(a) or 2.11(c), the Borrower may either pay in full the Obligations owed to such Affected Lender or substitute for such Affected Lender any Lender or any Affiliate or Approved Fund of any Lender or any other Eligible Lender acceptable (which acceptance shall not be unreasonably withheld or delayed) to the Administrative Agent (in each case, a “Substitute Lender”).

(b) Procedure. To substitute such Affected Lender or pay in full the Obligations owed to such Affected Lender, the Borrower shall deliver a notice to the Administrative Agent and such Affected Lender.

(b) No Obligor will, nor will it permit any other Obligor to, amend, adopt or terminate any Plan (i) unless such action could not reasonably be expected to have a Material Adverse Effect, or (ii) in any manner that could reasonably be expected to give the PBGC a sound and just basis to commence Proceedings against the Obligors on the basis that such action constitutes a subsequent change in connection with the Obligor’s termination or replacement of the defined benefit Retirement Income Plan for Pilots of US Airways, Inc. with the 2003 Pilots Defined Contribution Plan.

(c) No Obligor shall amend, restate, supplement or modify (or consent to or permit any amendment, restatement, supplement or modification of) its Investment Guidelines without the prior written consent of the Administrative Agent; provided, that, for the avoidance of doubt, this Section 6.10(c) shall not be deemed to prohibit the adoption of the Investment Guidelines by any Obligor.

Section 7.2 Remedies. During the continuance of any Event of Default, the Administrative Agent may, and at the request of the Requisite Lenders shall, declare the Loan, all interest thereon and all other amounts and Obligations payable under this Agreement to be immediately due and payable, whereupon the Loan, all such interest and all such amounts and Obligations shall become and be immediately due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower; provided, however, that upon the occurrence of an Event of Default specified in clause (f) or (g) of Section 7.1, the Loan, all such interest and all such amounts and Obligations shall automatically become and be immediately due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby expressly waived by the Borrower. In addition to the remedies set forth above, the Administrative Agent may exercise any remedies provided for by the Collateral Documents or any other remedies provided by applicable law.

ARTICLE VIII

THE ADMINISTRATIVE AGENT

Section 8.1 Appointment, Powers and Immunities. Each Lender hereby appoints and authorizes Citigroup North America, Inc. to act as its administrative agent and collateral agent hereunder with such powers as are specifically delegated to the Administrative Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Without limiting the foregoing, each Lender hereby authorizes the Administrative Agent to execute and deliver each of the Collateral Documents. The Administrative Agent (which term as used in this sentence and in Section 8.5 hereof and the first sentence of Section 8.6 hereof shall include reference to its affiliates and its own and its affiliates’ officers, directors, employees and agents):

(a) shall have no duties or responsibilities except those expressly set forth in this Agreement and the other Loan Documents, and shall not by reason of this Agreement or the other Loan Documents be a trustee or fiduciary for any party hereto;

(b) shall not be responsible to the Lenders for any recitals, statements, representations or warranties contained in this Agreement, or in any certificate or other document referred to or provided for in, or received by any of them under, this Agreement, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of any Loan Document or any other document referred to or provided for herein or therein or for any failure by the Borrower or any other Person to perform any of its obligations hereunder or thereunder;

(c) shall not be required to initiate or conduct any litigation or collection proceedings hereunder (and shall not commence an action or proceeding on behalf of any Lender without obtaining the consent of such Lender thereto); and

(d) shall not be responsible for any computation made in good faith under Section 6.4 hereof or for any other action taken or omitted to be taken by it hereunder or under any other

document or instrument referred to or provided for herein or therein or in connection herewith or therewith, except for its own gross negligence or willful misconduct.

The Administrative Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct (except for the gross negligence or willful misconduct) of or for the supervision of any such agents or attorneys-in-fact selected by it in good faith.

Section 8.2 Reliance by Administrative Agent. The Administrative Agent shall be entitled to conclusively rely upon any certification, notice or other communication (including, without limitation, any thereof by telephone, telecopy, email, telegram or cable) reasonably believed by it to be genuine and correct and to have been signed, made or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel and other experts selected by the Administrative Agent, as the case may be. As to any matters not expressly provided for by this Agreement, the Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder in accordance with instructions given by the Requisite Lenders, and such instructions of the Requisite Lenders and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders.

Section 8.3 Defaults. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default (other than a failure to make a payment of principal of or interest on the Loan) unless the Administrative Agent has received notice from a Lender or the Borrower specifying such Default and stating that such notice is a “Notice of Default”. In the event that the Administrative Agent receives a notice of a Default, the Administrative Agent shall give prompt notice thereof to the Lenders. The Administrative Agent shall (subject to Section 8.7 hereof) take such action with respect to any such Default as shall be directed by the Requisite Lenders, provided, that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interest of the Lenders except to the extent that this Agreement expressly requires that such action be taken, or not be taken, only with the consent or upon the authorization of the Requisite Lenders or all of the Lenders.

Section 8.4 Rights as a Lender. With respect to its Commitment and the Loan, if any, made by it, Citigroup (and any successor acting as Administrative Agent) in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as the Administrative Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. Citigroup (and any successor acting as Administrative Agent) and its affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to, make investments in and generally engage in any kind of banking, trust or other business with the Borrower as if it were not acting as the Administrative Agent, and Citigroup (and any such successor) and its affiliates may accept fees and other consideration from the Borrower for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

Section 8.5 Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed under Section 9.4 hereof, but without limiting the obligations of the Borrower under said Section 9.4) ratably in accordance with the aggregate principal amount of the Loan held by the Lenders (or, if no Loan is at the time outstanding, ratably in accordance with their respective Commitments), for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever (including without limitation legal fees and expenses) that may be imposed on, incurred by or asserted against the Administrative Agent arising out of or by reason of any investigation in any way relating to or arising out of this Agreement or any other documents contemplated by or referred to herein or therein or the transactions

contemplated hereby or thereby (including, without limitation, the costs and expenses that the Borrower is obligated to pay under Section 9.4 hereof, but excluding, unless an Event of Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder) or the enforcement of any of the terms hereof or thereof or of any such other documents, provided, that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the party to be indemnified. The obligations of the Lenders under this Section 8.5 shall survive the termination of this Agreement, the repayment of the Loan and the resignation or removal of the Administrative Agent.

Section 8.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender agrees that it has, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and decision to enter into this Agreement and that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement and the Notes. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Borrower of this Agreement and the Notes or any other document referred to or provided for herein or therein or to inspect the properties or books of the Borrower. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower that may come into the possession of the Administrative Agent or any of its affiliates.

Section 8.7 Failure to Act. Except for action expressly required of the Administrative Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or thereunder unless it shall receive further assurances to its satisfaction from the Lenders of their indemnification obligations under Section 8.5 hereof against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action.

Section 8.8 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower, and the Administrative Agent may be removed at any time with or without cause by the Requisite Lenders at no cost to the Borrower other than the payment of the fees of any successor Administrative Agent. Upon any such resignation or removal, the Requisite Lenders, in consultation with the Borrower, shall have the right to appoint a successor Administrative Agent, which shall be a bank that has an office in New York, New York or London, England. If no successor Administrative Agent shall have been so appointed by the Requisite Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Requisite Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a bank that has an office in New York, New York and that has a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as an Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent and shall notify the Lenders and the Borrower thereof, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. Notwithstanding the foregoing, no removal of the Administrative Agent shall be effective until all amounts then due and owing to the removed Administrative Agent shall be paid in full. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this

Section 10 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent.

Section 8.9 Release of Collateral or Guarantors. Each Lender hereby consents to the release and hereby directs the Administrative Agent to release (or, in the case of clause (b)(iii) below, release or subordinate) the following:

(a) any Subsidiary of the Borrower from its guaranty of any Obligation of any Obligor if all of the Capital Stock of such Subsidiary owned by the Borrower or any of its Subsidiaries are sold in a sale permitted under the Loan Documents (including pursuant to a waiver or consent), to the extent that, after giving effect to such sale, such Subsidiary would not be required to guaranty any Obligations pursuant to Section 5.8; and

(b) any Lien held by the Administrative Agent for the benefit of the Secured Parties against (i) any Collateral that is sold by an Obligor (A) in a sale permitted by the Loan Documents (including pursuant to a valid waiver or consent), to the extent all Liens required to be granted in such Collateral pursuant to Section 5.8 after giving effect to such sale have been granted and with respect to which the relevant Obligor complies with Section 2.5(b), as applicable, or (B) in connection with any Replacement Secured Financing with respect to which the relevant Obligor complies with Section 2.5(a), (ii) any Collateral to the extent the release of any Lien in such Collateral is permitted or required under any Loan Document (including, without limitation, the proviso in Section 5.8(b)) and (iii) all of the Collateral and all Obligors, upon (A) termination of the Commitments, (B) payment and satisfaction in full of all Loans and all other Obligations that the Administrative Agent has been notified in writing are then due and payable, (C) deposit of cash collateral with respect to all contingent Obligations as to which claims have been asserted or are pending, in amounts and on terms and conditions and with parties satisfactory to the Administrative Agent and each Indemnitee that is owed such Obligations and (D) to the extent requested by the Administrative Agent, receipt by the Secured Parties of mutual liability releases from the Obligors and the Administrative Agent, each in form and substance acceptable to the Administrative Agent.

Each Lender hereby directs the Administrative Agent, and the Administrative Agent hereby agrees, upon receipt of reasonable advance notice from the Borrower, to execute and deliver or file such documents and to perform other actions reasonably necessary to release the guaranties and Liens when and as directed in this Section 8.9; provided, that the Administrative Agent shall not be obligated to release any guaranty or Lien pursuant to this Section 8.9 until its receipt from the Borrower of an Officer’s Certificate certifying that such release complies with this Section 8.9, and the Administrative Agent shall be fully protected in relying on such Officer’s Certificate in connection therewith.

Section 8.10 Joint Lead Arrangers, Bookrunner, Syndication Agent and Documentation Agent. Notwithstanding anything herein to the contrary the Joint Lead Arrangers, the Bookrunner, the Syndication Agent and the Documentation Agent named on the cover page of this Agreement shall not, in their capacities as such, have any duties or liabilities under this Agreement.

No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

(c) Non-Consenting Lenders. In connection with any proposed amendment, modification, waiver or termination requiring the consent of all affected Lenders, if the consent of the Requisite Lenders is obtained, but the consent of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this Section 9.1 being referred to as a “Non-Consenting Lender”), then, so long as the Lender that is acting (or an Affiliate of which is acting) as the Administrative Agent is not a Non-Consenting Lender, at the Borrower’s request and at its sole cost and expense, the Administrative Agent or an Eligible Lender that is acceptable to the Administrative Agent, and, so long as no Event of Default shall have occurred and be continuing, the Borrower, shall have the right with the Administrative Agent’s consent and in the Administrative Agent’s sole discretion (but shall have no obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon the Administrative Agent’s request, sell and assign to the Lender that is acting as the Administrative Agent or such Eligible Lender, all of the portion of the Loan of such Non-Consenting Lender for an amount equal to the principal balance of such portion of the Loan held by the Non-Consenting Lender and all accrued interest and fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment and Acceptance; provided, however, that at the time of such replacement, such assignee consents to the proposed amendment, modification, waiver or termination; provided, further, that the failure of any Non-Consenting Lender to execute any such Assignment and Acceptance shall not render such purchase and sale (or the corresponding assignment) invalid.

Section 9.2 Assignments and Participations; Successors and Assigns.

(a) Right to Assign. Each Lender may sell, transfer, negotiate or assign all or a portion of its rights and obligations hereunder (including all or a portion of its Commitments and its rights and obligations with respect to the Loan) to (i) any existing Lender, (ii) any Affiliate or Approved Fund of any existing Lender or (iii) any other Eligible Lender acceptable (which acceptance shall not be unreasonably withheld or delayed) to the Administrative Agent and, as long as no Event of Default is continuing, the Borrower; provided, however, that (x) such assignments must be ratable among the obligations owing to and owed by such Lender with respect to the Loan Facility, (y) the aggregate outstanding principal amount (determined as of the Closing Date of the applicable Assignment and Acceptance) of the Loan and Commitments subject to any such assignment shall be an integral multiple of $1,000,000, unless such assignment is made to an existing Lender or an Affiliate or Approved Fund of any existing Lender, is of the assignor’s (together with its Affiliates and Approved Funds) entire interest in the Loan Facility or is made with the prior consent of the Borrower and the Administrative Agent and (z) the consent of the Borrower shall not be required for any assignment by the Lenders party hereto on the Closing Date made in connection with the primary syndication of the Loan Facility of their respective Commitments and Loan held on the Closing Date.

(b) Procedure. The parties to each assignment made in reliance on clause (a) above (other than those described in clause (d) or (e) below) shall deliver to the Administrative Agent (and the Administrative Agent shall keep a copy of all documents required to be delivered) the following: (i) an Assignment and Acceptance, executed by the assignor(s) and the assignees(s), evidencing such assignment; (ii) any existing Note subject to such assignment (or any affidavit of loss therefor acceptable to the Administrative Agent); (iii) any tax forms required to be delivered pursuant to Section 2.11(f), and (iv) an assignment fee in the amount of $3,500; provided, that (1) if an assignment by a Lender is made to an Affiliate or an Approved Fund of such assigning Lender, then no assignment fee shall be due in connection with such assignment, and (2) if an assignment by a Lender is made to an assignee that is not an Affiliate or Approved Fund of such assigning Lender, and concurrently to one or more Affiliates or Approved Funds of such assignee, then only one assignment fee of $3,500 shall be due in connection with such assignment. Upon receipt of all the foregoing, and conditioned upon such receipt and upon the Administrative Agent consenting to such Assignment and Acceptance, from and after the Closing Date

specified in such Assignment and Acceptance, the Administrative Agent shall record or cause to be recorded in the Register the information contained in such Assignment and Acceptance.

(c) Effectiveness. Effective upon the entry of such record in the Register, (i) such assignee shall become a party hereto and, to the extent that rights and obligations under the Loan Documents have been assigned to such assignee pursuant to such Assignment and Acceptance, shall have the rights and obligations of a Lender, (ii) any applicable Note shall be transferred to such assignee through such entry and (iii) the assignor thereunder shall, to the extent that rights and obligations under this Agreement have been assigned by it pursuant to such Assignment, relinquish its rights (except for those surviving the termination of the Commitments and the payment in full of the Obligations) and be released from its obligations under the Loan Documents, other than those relating to events or circumstances occurring prior to such assignment (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under the Loan Documents, such Lender shall cease to be a party hereto except that each Lender agrees to remain bound by Article VIII, Section 9.5 and Section 9.6 to the extent provided in Section 8.11); provided, however, that the Obligors shall not be obligated to pay any greater amount under Section 2.9(b) or Section 2.11 to such assignee than the Obligors would have been obligated to pay to the assigning Lender as of the date of such assignment in such Sections prior to such assignment.

(d) Grant of Security Interests. In addition to the other rights provided in this Section 9.2, each Lender may, without the consent of the Administrative Agent or the Borrower, grant a security interest in, or otherwise assign as collateral, any of its rights under this Agreement, whether now owned or hereafter acquired (including rights to payments of principal or interest on the Loan), to (A) any federal reserve bank (pursuant to Regulation A of the Federal Reserve Board), without notice to the Administrative Agent or (B) any holder of, or trustee for the benefit of the holders of, such Lender’s securities by notice to the Administrative Agent; provided, however, that no such holder or trustee, whether because of such grant or assignment or any foreclosure thereon (unless such foreclosure is made through an assignment in accordance with clause (a) above), shall be entitled to any rights of such Lender hereunder and no such Lender shall be relieved of any of its obligations hereunder.

(e) Participants and SPVs. In addition to the other rights provided in this Section 9.2, each Lender may, (x) with notice to the Administrative Agent, grant to an SPV the option to make all or any part of the Loan that such Lender would otherwise be required to make hereunder (and the exercise of such option by such SPV and the making of the Loan pursuant thereto shall satisfy the obligation of such Lender to make such Loan hereunder) and such SPV may assign to such Lender the right to receive payment with respect to any Obligation and (y) without notice to or consent from the Administrative Agent or the Borrower, sell participations to one or more Persons in or to all or a portion of its rights and obligations under the Loan Documents (including all its rights and obligations with respect to the Loan) (any such purchaser of a participation being referred to as a “Participant”); provided, however, that, whether as a result of any term of any Loan Document or of such grant or participation, (i) no such SPV or Participant shall have a commitment, or be deemed to have made an offer to commit, to make the Loan hereunder, and, except as provided in the applicable option agreement, none shall be liable for any obligation of such Lender hereunder, (ii) such Lender’s rights and obligations, and the rights and obligations of the Obligors and the Secured Parties towards such Lender, under any Loan Document shall remain unchanged and each other party hereto shall continue to deal solely with such Lender, which shall remain the holder of the Obligations in the Register, except that (A) each such Participant and SPV shall be entitled to the benefit of Sections 2.9, 2.10 and 2.11, but only to the extent such Participant or SPV delivers the tax forms such Lender is required to collect pursuant to Section 2.11(f) and then only to the extent of any amount to which such Lender would be entitled in the absence of any such grant or participation and (B) each such SPV may receive other payments that would otherwise be made to such Lender with respect to the Loan funded by such SPV to the extent provided in the applicable option

agreement and set forth in a notice provided to the Administrative Agent by such SPV and such Lender, provided, however, that in no case (including pursuant to clause (A) or (B) above) shall an SPV or Participant have the right to enforce any of the terms of any Loan Document, and (iii) the consent of such SPV or Participant shall not be required (either directly, as a restraint on such Lender’s ability to consent hereunder or otherwise) for any amendments, waivers or consents with respect to any Loan Document or to exercise or refrain from exercising any powers or rights such Lender may have under or in respect of the Loan Documents (including the right to enforce or direct enforcement of the Obligations), except for those described in clauses (2) and (3) of Section 9.1(a)(i) and, in the case of Participants, except for those described in Section 9.1(a)(i)(5). Notwithstanding the foregoing, each Lender agrees that none of the following Persons shall become a Participant hereunder: (I) an airline, a commercial aircraft operator, an air freight forwarder or an entity principally engaged in the business of parcel transport by air, or (II) an Affiliate of any Person described in clause (I) above. No party hereto shall institute (and the Borrower shall cause each other Obligor not to institute) against any SPV grantee of an option pursuant to this clause (e) any bankruptcy, reorganization, insolvency, liquidation or similar proceeding, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper of such SPV; provided, however, that each Lender having designated an SPV as such agrees to indemnify each Indemnitee against any Liability that may be incurred by, or asserted against, such Indemnitee as a result of failing to institute such proceeding (including a failure to get reimbursed by such SPV for any such Liability). The agreement in the preceding sentence shall survive the termination of the Commitments and the payment in full of the Obligations.

(f) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns; provided that except as otherwise expressly provided herein, no Obligor may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lenders and the Administrative Agent (and any attempted assignment or transfer by an Obligor without such consent shall be null and void).

Section 9.3 Costs and Expenses. Whether or not the transactions contemplated hereby shall be consummated, the Obligors agree to pay promptly (i) all reasonable costs and expenses incurred by the Administrative Agent in connection with the negotiation, preparation, execution and delivery of the Loan Documents and all documents relating thereto (including reasonable legal fees and expenses), (ii) all reasonable costs and expenses incurred by the Administrative Agent in connection with any consents, amendments, waivers or other modifications hereto (including reasonable legal fees and expenses) and (iii) all costs and expenses, including reasonable legal fees and expenses incurred by the Administrative Agent and the Lenders in enforcing any Obligations of, or in collecting any payments due from, the Obligors hereunder or under the other Loan Documents, including any such costs and expenses incurred after the filing of a bankruptcy or insolvency proceeding with respect to any Obligor.

Section 9.4 Indemnities.

(a) Each Obligor agrees to indemnify, hold harmless and defend the Administrative Agent, each Lender and each of their respective Related Persons (each such Person being an “Indemnitee”) from and against all Liabilities (including brokerage commissions, fees and other compensation) that may be imposed on, incurred by or asserted against any such Indemnitee in any matter relating to or arising out of, in connection with or as a result of (i) any Loan Document, any Obligation (or the repayment thereof), the use or intended use of the proceeds of the Loan or any securities filing of, or with respect to, the Borrower and its Subsidiaries, (ii) any commitment letter, proposal letter or term sheet with any Person or any Contractual Obligation, arrangement or understanding with any broker, finder or consultant, in each case entered into by or on behalf of the Borrower, its Subsidiaries or any Affiliate of any of them in connection with any of the foregoing and any Contractual Obligation entered into in connection with any Platform, (iii) any actual or prospective investigation, litigation or other

proceeding, whether or not brought by any such Indemnitee or any of its Related Persons, any holders of securities or creditors (and including reasonable attorneys’ fees in any case), whether or not any such Indemnitee, Related Person, holder or creditor is a party thereto, and whether or not based on any securities or commercial law or regulation or any other Requirement of Law or theory thereof, including common law, equity, contract, tort or otherwise, or (iv) any other act, event or transaction related, contemplated in or attendant to any of the foregoing (collectively, the “Indemnified Matters”); provided, however, that the Obligors shall not have any liability under this Section 9.4 to any Indemnitee with respect to any Indemnified Matter, and no Indemnitee shall have any liability with respect to any Indemnified Matter other than (to the extent otherwise liable), to the extent such liability has resulted primarily from the gross negligence or willful misconduct of such Indemnitee, as determined by a court of competent jurisdiction in a final non-appealable judgment or order. Furthermore, each Obligor waives and agrees not to assert against any Indemnitee any right of contribution with respect to any Liabilities that may be imposed on, incurred by or asserted against any Related Person. Each of the Borrower, the Administrative Agent and the Lenders also agrees not to assert any claim against the Administrative Agent, any Lender, the Borrower, any of their Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, for consequential, indirect, special or punitive damages arising out of or otherwise relating to this Agreement or any of the other Loan Documents or any of the transactions contemplated hereby or thereby or the actual or proposed use of the proceeds of the Loan.

(b) Without limiting the foregoing, “Indemnified Matters” includes all Environmental Claims, including those arising from, or otherwise involving, any property of the Borrower or any of its Subsidiaries or any actual, alleged or prospective damage to property or natural resources or harm or injury alleged to have resulted from any Release of Hazardous Materials on, upon or into such property or natural resource or any property on or contiguous to any real property of the Borrower or any of its Subsidiaries, whether or not, with respect to any such Environmental Claims, any Indemnitee is a mortgagee pursuant to any leasehold mortgage, a mortgagee in possession, the successor-in-interest to the Borrower or any of its Subsidiaries or the owner, lessee or operator of any property of the Borrower or any of its Subsidiaries through any foreclosure action, in each case except to the extent such Environmental Claims (i) are incurred solely following foreclosure by any Secured Party or following any Secured Party having become the successor-in-interest to any Obligor and (ii) are attributable solely to acts of such Indemnitee.

Section 9.5 Right of Set-Off. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default, to the fullest extent permitted by law, the Administrative Agent, each Lender and each of their respective Affiliates are hereby authorized by the Obligors at any time or from time to time, with notice to the Obligors and to each other Lender and the Administrative Agent, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other Indebtedness at any time held or owing by the Administrative Agent or that Lender to or for the credit or the account of any Obligor against and on account of the obligations and liabilities of such Obligor to the Administrative Agent or that Lender under this Agreement, the Guaranty, the Notes and the other Loan Documents, including, but not limited to, all claims of any nature or description arising out of or connected with this Agreement, the Guaranty, the Notes, or any other Loan Document, irrespective of whether or not (i) the Administrative Agent or that Lender shall have made any demand hereunder or (ii) the principal of or the interest on the Loan or any other amounts due hereunder shall have become due and payable pursuant to Section 7.2 and although said obligations and liabilities, or any of them, may be contingent or unmatured.

Section 9.6 Sharing of Payments, Etc. The Lenders hereby agree among themselves that if any of them shall, whether by voluntary payment, by realization upon security, through the exercise of any right of set-off or banker’s lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents or otherwise, or as adequate protection of a deposit treated as cash collateral under the Bankruptcy Code, receive payment or reduction of a proportion of the aggregate amount of principal, interest, fees and other amounts then due and owing to the Lenders hereunder or under the other Loan Documents (collectively, the “Aggregate Amounts Due”) which is greater than the proportion received by any other Lender in respect of the Aggregate Amounts Due to such other Lender, then the Lender receiving such proportionately greater payment shall (i) notify the Administrative Agent and each other Lender of the receipt of such payment and (ii) apply a portion of such payment to purchase participations equal to the portion of the Aggregate Amounts Due to the other Lenders (which participations shall be deemed to have been purchased and payments made simultaneously upon the receipt by the seller of its portion of such payment, and which participations will be permitted notwithstanding any prohibition to the contrary in Section 9.2(e)) so that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion to the Aggregate Amounts Due to them, provided that if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of the Borrower or otherwise, those purchases or other payments shall be rescinded and the purchase prices paid for such participations or other payments shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. The Borrower expressly consents to the foregoing arrangement and agrees that any holder of a participation so purchased may exercise any and all rights of banker’s lien, set-off or counterclaim with respect to any and all monies owing by the Borrower to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder.

Section 9.7 Notices.

(a) Subject to the provisions of clauses (b), (c) and (d) below, all notices, requests, instructions, directions and other communications provided for herein (including, without limitation, any modifications of, or waivers, requests or consents under, this Agreement) shall be given or made in writing (including, without limitation, by telecopy) delivered, if to the Borrower to its address specified in Annex A hereto, or the Administrative Agent, to its “Address for Notices” specified opposite its name on its signature page hereto, and if to any Lender, to its “Address for Notices” specified opposite its name on its signature page hereto; or, as to any party, at such other address as shall be designated by such party in a notice to the Administrative Agent and the Borrower. Except as otherwise provided in this Agreement, all such communications shall be deemed to have been duly given upon receipt of a legible copy thereof, in each case given or addressed as aforesaid. All such communications to the Administrative Agent provided for herein by telecopy shall be confirmed in writing promptly after the delivery of such communication (it being understood that non-receipt of written confirmation of such communication shall not invalidate such communication).

(b) The Borrower hereby agrees that it will provide to the Administrative Agent all information, documents and other materials that it is obligated to furnish to the Administrative Agent pursuant to this Agreement or the other Loan Documents, including, without limitation, all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (i) relates to the payment of any principal or other amount due under this Agreement or the other Loan Documents prior to the scheduled date therefor, (ii) provides notice of any Default or Event of Default under this Agreement or the other Loan Documents or (iii) is required to be delivered to satisfy any condition precedent to the occurrence of the Closing Date (all such non-excluded communications being referred to herein collectively as “Communications”), by transmitting the Communications in an electronic/soft medium in a format acceptable to the Administrative Agent to xxxxxxxxxxxxxxx@xxxxxxxxx.xxx.

NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, THE “AGENT PARTIES”) HAVE ANY LIABILITY TO THE BORROWER, ANY LENDER OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF THE BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

(d) The Administrative Agent agrees that the receipt of the Communications by the Administrative Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Administrative Agent for purposes hereof. Each Lender agrees that notice to it (as provided in the next sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Lender for purposes hereof. Each Lender agrees (i) to provide to the Administrative Agent in writing (including by electronic communication), promptly after the date of this Agreement or the other Loan Documents, an e-mail address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address.

(e) Nothing herein shall prejudice the right of the Administrative Agent or any Lender to give any notice or other communication pursuant hereto in any other manner specified herein.

Section 9.8 No Waiver; Remedies. No failure on the part of any Lender or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

Section 9.9 Governing Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

THE PARTIES HERETO HEREBY IRREVOCABLY WAIVE ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH ANY OF THEM MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

(b) Service of Process.

To the extent that any Obligor makes a payment or payments to the Administrative Agent for the account of any Lender (each, a “Payee”) or any Payee receives payment from exercise of their rights of setoff, and such payment or payments or the proceeds of such setoff or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party, then (i) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied, and all rights and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred and (ii) each Payee shall pay and return such amount to the Administrative Agent as the Administrative Agent may be required to disgorge or otherwise pay to a trustee, receiver or any other party in respect of the portion of the payment from such Obligor distributed by the Administrative Agent to such Payee hereunder.
