SECURITY AGREEMENT

THIS SECURITY AGREEMENT, dated as of August 1, 2006 (this “Security Agreement”), is by and between AIRTRAN AIRWAYS, INC. (the “Borrower”) and BNP PARIBAS S.A. (ACTING THROUGH ITS PARIS BRANCH), as Security Agent for the Lenders (together with its successors hereunder in such capacity, the “Security Agent”).

RECITALS:

WHEREAS, Borrower desires by this Security Agreement, among other things (i) to provide for the issuance by Borrower to the Lenders of Loan Certificates evidencing participation by the Lenders in the secured loans as provided in the Credit Agreement, and (ii) to provide for the assignment, mortgage and pledge by Borrower to Security Agent, as the Collateral hereunder, among other things, certain of Borrower’s right, title and interest in and to the Purchase Agreement and the GTA, as security for, among other things, Borrower’s obligations to the Lenders, and for the benefit and security of the Lenders;

WHEREAS, all things have been done to make the Loan Certificates, when executed by Borrower and issued and delivered hereunder, the valid obligations of Borrower; and

WHEREAS, all things necessary to make this Security Agreement the valid, binding and legal obligation of Borrower, for the uses and purposes herein set forth and in accordance with its terms, have been done and performed and have happened;

GRANTING CLAUSE:

NOW, THEREFORE, THIS SECURITY AGREEMENT WITNESSETH, that, to secure the prompt payment of the principal amount of, interest on, and all other amounts due with respect to all Loan Certificates and (subject to Section 14 of the Credit Agreement) the Related Notes, and to secure Borrower’s prompt and complete payment, performance and observance of (x) all the agreements, covenants, and provisions herein, in the Credit Agreement and the other Operative Agreements, the Loan Certificates and (subject to Section 14 of the Credit Agreement) in the Loan Agreements, the Related Mortgages and the Related Notes, for the benefit of the Lenders and (subject to Section 14 of the Credit Agreement) the holders of the Related Notes, and (y) all other Secured Obligations, and in consideration of the premises and of the covenants herein, and of the acceptance of the Loan Certificates by the holders thereof, and for other good and valuable consideration the receipt and adequacy whereof are hereby acknowledged, Borrower hereby grants to Security Agent (and its successors in trust and assigns), for the security and benefit of the Lenders and (subject to Section 14 of the Credit Agreement) the holders of the Related Notes and all other Persons holding Secured Obligations, a security interest in and Lien on all Borrower’s right, title and interest in, to, and under the following described property, rights, and privileges, whether now existing or hereafter acquired (which, collectively, together with all property hereafter specifically subject to the Lien of this Security Agreement by the terms hereof or any supplement hereto, are included within, and are referred to as, the “Collateral”):

(1) Subject to the terms and conditions of the Consent and Agreement, the Purchase Agreement, including, without limitation, (i) the right to purchase each of the Aircraft pursuant to and in accordance with the Purchase Agreement upon valid tender by Airframe Manufacturer; (ii) all claims for damages in respect of each of the Aircraft arising as a result of any default by Airframe Manufacturer under the Purchase Agreement or by any vendor or other supplier of components or other parts or equipment installed on or in any of the Aircraft referred to therein, including, without limitation, all warranty, service life policy and indemnity provisions contained in the Purchase Agreement and all claims thereunder; (iii) any and all rights of Borrower to compel performance of the terms of the Purchase Agreement in respect of the Aircraft; and (iv) all of Borrower’s rights and interests in or arising out of any payments or deposits made or to be made by Borrower to Airframe Manufacturer or amounts paid, or to be paid, by Airframe Manufacturer to Borrower in respect of the Aircraft, together with all rights, powers, privileges, options and other benefits of Borrower in respect thereof, including, without limitation, the right to make all waivers and agreements, to give and receive all notices and other instruments or communications, and to take such action upon the occurrence of a default in respect of such provisions, including the commencement, conduct and consummation of legal, administrative or other proceedings, as shall be permitted thereby or by law, and to do any and all other things which Borrower is or may be entitled to do in respect of such provisions;

(2) Subject to the terms and conditions of the Engine Consent and Agreement, the GTA, including, without limitation, (i) all claims for damages in respect of each of the Engines arising as a result of any default by the Engine Manufacturer under the GTA or by any vendor or other supplier of components or other parts or equipment installed on or in any of the Engines referred to therein, including, without limitation, all warranty and indemnity provisions contained in the GTA and all claims thereunder; and (ii) any and all rights of Borrower to compel performance of the terms of the GTA in respect of the Engines, together with all rights, powers, privileges, options and other benefits of Borrower in respect thereof, including, without limitation, the right to make all waivers and agreements, to give and receive all notices and other instruments or communications, and to take such action upon the occurrence of a default in respect of such provisions, including the commencement, conduct and consummation of legal, administrative or other proceedings, as shall be permitted thereby or by law, and to do any and all other things which Borrower is or may be entitled to do in respect of such provisions;

(3) all payments or proceeds with respect to either the Purchase Agreement or the GTA in respect of the Aircraft and/or the Engines or any part thereof as the result of the sale or other disposition thereof, and all estate, right, title and interest of every nature whatsoever of Borrower in and to the same and every part thereof;

(4) all monies and securities deposited or required to be deposited with Security Agent pursuant to any term of this Security Agreement or required to be held by Security Agent hereunder;

(5) any and all property that may, from time to time, by delivery or by other writing of any kind, for the purposes hereof be in any way subjected to the lien and the security interest hereof or be expressly conveyed, mortgaged, assigned, transferred, deposited, in which a security interest may be granted by the Borrower and/or pledged by the Borrower, or by any Person authorized to do so on its behalf or with its consent, to and with the Security Agent, including (without limitation) under and pursuant to any of the Related Mortgages, who is hereby authorized to receive the same at any and all times as and for additional security hereunder; and

(6) all proceeds of the foregoing.

Any and all properties referred to in this Granting Clause which are hereafter acquired by Borrower, shall, without further conveyance, assignment or act by Borrower or Security Agent thereby become and be subject to the security interest hereby granted as fully and completely as though specifically described herein; provided, however, that all rights and interests in and to the Purchase Agreement and the GTA as and to the extent the same relate to aircraft and engines other than the Aircraft and the Engines are reserved to and retained by Borrower.

Anything in this Security Agreement to the contrary notwithstanding:

(1) Borrower shall at all times remain liable (A) to Airframe Manufacturer to perform all the duties and obligations of “Customer” under the Purchase Agreement, and (B) to Engine Manufacturer to perform all the duties and obligations of “Airline” under the GTA, in each case to the same extent as if this Security Agreement had not been executed;

(2) Security Agent’s exercise of any of the rights assigned hereunder shall not release Borrower from any of its duties or obligations to Airframe Manufacturer under the Purchase Agreement or to Engine Manufacturer under the GTA, except to the extent that such exercise constitutes performance of such duties and obligations;

(3) except as provided in the next paragraph, neither Security Agent nor any Lender shall have any obligation or liability under the Purchase Agreement or the GTA by reason of, or arising out of, this Security Agreement, or be obligated to perform any of Borrower’s obligations or duties under the Purchase Agreement or the GTA, or to make any payment thereunder, or to make any inquiry as to the sufficiency of any payment received by any of them, or to present or file any claim or to take any other action to collect or enforce any claim for any payment assigned under this Security Agreement; and

(4) During the existence of an Event of Default, Security Agent shall be entitled to exercise the rights and powers under and with respect to the Purchase Agreement, as and to the extent provided in the Consent and Agreement, and with respect to the GTA, as and to the extent provided in the Engine Consent and Agreement, without the necessity of enforcing the Lien of this Security Agreement or exercising any remedies hereunder.

Notwithstanding anything to the contrary in this Security Agreement, the Consent and Agreement or the Engine Consent and Agreement, but without in any way releasing Borrower from any of its duties or obligations under the Purchase Agreement, the GTA, or this Security Agreement, Security Agent confirms for the benefit of Airframe Manufacturer and Engine Manufacturer that, insofar as the provisions of the Purchase Agreement or the GTA relate to the Aircraft or the Engines (respectively), in exercising any rights under the Purchase Agreement or under the GTA, or in making any claim with respect to the Aircraft, Engines or other goods and services delivered or to be delivered pursuant to the Purchase Agreement or the GTA, the terms and conditions thereof (including warranty disclaimers, liability exclusions, indemnity, and insurance) shall apply to and bind Security Agent to the same extent as Borrower. At Borrower’s cost and expense, Security Agent further agrees, expressly for the benefit of Airframe Manufacturer and Engine Manufacturer, that upon the written request of Airframe Manufacturer or Engine Manufacturer, Security Agent will promptly execute and deliver such further assurances and documents and take such further action as Airframe Manufacturer or Engine Manufacturer reasonably requests in order to obtain the full benefits of Security Agent’s agreements in this paragraph. Borrower and Security Agent understand and acknowledge that no further assignment of the Purchase Agreement or GTA, including, without limitation, assignments for security purposes, are permitted without the express written consent of Airframe Manufacturer or Engine Manufacturer (as the case may be) except as otherwise provided in the Consent and Agreement and the Engine Consent and Agreement.

Notwithstanding any of the foregoing provisions of this Granting Clause, but subject to the express provisions of the other articles of this Security Agreement, so long as an Event of Default has not occurred and is continuing and, if legally permitted by Law to do so, Security Agent has not commenced the exercise of remedies under Section 4 hereof and except as provided in the Consent and Agreement and in the Engine Consent and Agreement, Borrower shall have the right, to the exclusion of Security Agent and any others claiming by, through or under Security Agent, to exercise in Borrower’s name all rights and powers of (x) the “Customer” with respect to the Aircraft under the Purchase Agreement and (y) the “Airline” with respect to the Engines under the GTA, provided, that, Borrower may not enter into any change order or other termination, amendment, modification or supplement to or give or accept any waiver or consent under, either the Purchase Agreement or the GTA to the extent related to the Collateral without the written consent of Security Agent if such change order, amendment, modification, supplement, waiver or consent would:

(1) change the time of or the amount of any Advance or the manner in which any Advance can be returned or credited to Borrower under the Purchase Agreement;

(2) result in the rescission, cancellation or termination of the Purchase Agreement or the GTA, except with respect to a rescission, cancellation or termination to the extent Airframe Manufacturer has the right to rescind, cancel or terminate the Purchase Agreement pursuant to the Consent and Agreement;

(3) result in the increase in the purchase price with respect to an Aircraft unless Borrower pays the amount of such increase to Airframe Manufacturer as an additional advance payment under the Purchase Agreement;

(4) materially diminish the rights assigned hereunder to, or potentially increase the liabilities and obligations of, Security Agent; or

(5) modify the configuration and/or specification of an Aircraft in a manner which diminishes the value, utility or useful life of such Aircraft;

provided, if Borrower seeks to effectuate any change order, amendment, modification, supplement, waiver or consent which would materially diminish the rights assigned hereunder to, or potentially increase the liabilities and obligations of, Security Agent or modify the configuration and/or specification of an Aircraft in a manner which diminishes the value, utility or useful life of such Aircraft, Borrower shall give prior written notice to Security Agent thereof and Security Agent shall have ten (10) Business Days after receipt of such notice to object to such change order, amendment, modification, supplement, waiver or consent.

HABENDUM CLAUSE:

TO HAVE AND TO HOLD all and singular the aforesaid property unto Security Agent, its successors and assigns, in trust for the benefit and security of the Lenders, and for the uses and purposes and subject to the terms and provisions set forth in this Security Agreement.

Borrower, Agent and Security Agent further agree as follows:

1. DEFINITIONS

The terms defined in Annex A, when capitalized as in Annex A, have the same meanings when used in this Security Agreement. Annex A also contains rules of usage that control construction in this Security Agreement.

2. THE CERTIFICATES

2.1 Form of Loan Certificates.

The Loan Certificates shall be substantially in the form of Exhibit A.

2.2 Terms of Loan Certificates; Drawings.

(a) On the Borrowing Date coinciding with the Effective Date, Borrower shall issue a Series of Loan Certificate to each Lender in an aggregate original principal amount equal to such Lender’s Maximum Commitment in respect of each Aircraft. Borrower shall be entitled to make Drawings under each Loan Certificate in accordance with Section 2(a) of the Credit Agreement.

(b) Each Loan Certificate shall bear interest on the unpaid principal amount thereof from time to time outstanding from and including the date thereof until such principal amount is paid in full. Such interest shall accrue with respect to each Interest Period at the Applicable Rate in effect for such Interest Period and shall be payable in arrears on each Interest Payment Date and on the date such Loan Certificate is paid in full. Interest hereunder and under the Loan Certificates shall be calculated on the basis of a year of 360 days and actual number of days

elapsed. If any amount payable under the Loan Certificates or under the Operative Agreements falls due on a day which is not a Business Day, then such amount shall be payable on the next succeeding Business Day; provided, that in the case of principal of and interest on the Loan Certificates payable on a Interest Payment Date, if by virtue of such extension such payment would fall in the next succeeding month, such sum shall be payable on the next preceding Business Day. Notwithstanding any provisions in the Operative Agreements to the contrary, if the Interest Period in respect of a Series of Loan Certificates is scheduled to commence on a date that is less than one (1) month prior to the scheduled Delivery Date of the Aircraft to which such Series relates, Borrower, upon written notice to Security Agent given by Borrower within three (3) Business Days prior to the commencement of such Interest Period, may designate that, for purposes of such Series of Loan Certificates, such Interest Period shall end on such scheduled Delivery Date and the Applicable Rate for such Interest Period shall be calculated accordingly.

(c) The principal amount of each Loan Certificate shall be due and payable in full upon the earlier of (1) the Delivery Date of the Aircraft to which such Loan Certificate relates, but only with respect to the applicable Series of Loan Certificates; (2) three (3) months following the last day of the Scheduled Delivery Month of the Aircraft to which such Loan Certificate relates, but only with respect to the applicable Series of Loan Certificates; and (3) the Commitment Termination Date (the “Maturity Date”). The “Scheduled Delivery Month” in respect of an Aircraft, for all purposes of the Operative Agreements, shall mean the scheduled delivery month notified by Borrower as being the scheduled delivery month for such Aircraft, which Scheduled Delivery Month shall fall within the same Scheduled Delivery Quarter for such Aircraft and which notice Borrower agrees to provide to Security Agent no later than twelve (12) months prior to the last day of such Scheduled Delivery Month.

(d) Each Loan Certificate shall bear interest at the Past Due Rate on any unpaid principal amount thereof and, to the extent permitted by applicable Law, interest (other than interest accrued at the Past Due Rate) and other amounts due thereunder and hereunder, not paid when due (whether at stated maturity, by acceleration or otherwise), for any period during which the same shall be overdue, payable on demand by the respective Lender (which may be given through Security Agent).

(e) The Loan Certificates shall be executed on behalf of Borrower by one of its authorized officers. Loan Certificates bearing the signatures of individuals who were at any time the proper officers of Borrower shall bind Borrower, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the delivery of such Loan Certificates or did not hold such offices at the respective dates of such Loan Certificates. No Loan Certificates shall be issued hereunder except those provided for in Section 2.2(a) and any Loan Certificates issued in exchange or replacement therefor pursuant to the terms of this Security Agreement.

2.3 Taxes.

(a) Security Agent (as agent for Borrower) shall exclude and withhold at the appropriate rate from each payment of principal of, interest on, and other amounts due from Borrower to any Lender hereunder or under each Loan Certificate any and all withholding taxes applicable thereto as required by Law. Security Agent agrees (1) to act as such withholding agent in accordance with Treasury Regulation 1.1441-1(b)(2)(iv) and, in connection therewith, (2)

whenever any present or future taxes or similar charges are required by applicable Law to be withheld with respect to any amounts payable by Borrower hereunder or in respect of the Loan Certificates, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Lenders, (3) to file any necessary withholding tax returns or statements when due, and (4) as promptly as possible after the payment thereof, to deliver to each Lender (with a copy to Borrower) appropriate receipts, if reasonably available, showing the payment thereof, together with such additional documentary evidence as any such Lender reasonably requests from time to time. In accordance with the foregoing, Security Agent further agrees to provide Borrower with a properly completed and executed Form W-8IMY certifying that Security Agent has agreed to be treated as a U.S. Person with respect to payments received from Borrower hereunder. Such Form W-8IMY shall be provided by Security Agent prior to the due date of any amounts payable by Borrower hereunder. For the avoidance of doubt, by failing to comply with this Section 2.3(a), Security Agent shall be in breach of the foregoing covenant and responsible for damages resulting therefrom.

(b) In the case of a Lender that is a Non-U.S. Person, such Lender shall furnish such Security Agent with a properly completed and executed withholding certificate on Form W-8BEN, W-8IMY or W-8ECI (or any successor forms) and/or such other applicable documentation as may be necessary or desirable to enable such Lender to claim an exemption from, or reduced rate of, such taxes. Provided that such Lender has furnished Security Agent with the requested forms and other documentation duly executed by such Lender and has not notified Security Agent of the withdrawal or inaccuracy of such form prior to the date of each interest payment, only the reduced amount (if any) required by applicable law or treaty shall be withheld from payments under the Loan Certificates held by such Lender in respect of United States federal income tax. In the case of a Lender that is a U.S. Person and (1) not an Exempt Recipient that has furnished to the Security Agent a properly completed and currently effective U.S. Treasury Form W-9 or (2) that is an Exempt Recipient (not required to deliver an IRS Form W-8), no amount shall be withheld from payments under the Loan Certificates held by such Lender in respect of United States federal income tax. If any Lender has notified Security Agent that any of the foregoing forms or certificates is withdrawn or inaccurate, or if the Internal Revenue Code or the regulations thereunder or the administrative interpretation thereof are at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Loan Certificates held by such Lender, or if such withholding is otherwise required, Security Agent agrees to withhold from each payment due to the relevant Lender withholding taxes at the appropriate rate under applicable Law, and will, as more fully provided above, on a timely basis, deposit such amounts with an authorized depository and make such returns, filings, and other reports in connection therewith, and in the manner required under applicable Law. For purposes of this paragraph, an “Exempt Recipient” is a Person described in Code §6049(b)(4). Notwithstanding any other provision of this paragraph, a Lender that is a Non-U.S. Person shall not be required to deliver any form pursuant to this paragraph that such Lender is not legally able to deliver.

(c) If, for any reason, Security Agent (or any successor institution acting as Security Agent) is unable to provide Borrower with a properly completed and executed Form W-8IMY, Borrower shall exclude and withhold at the appropriate rate from each payment of Original Amount of, interest on, and other amounts due from Borrower to any Lender hereunder or under each Loan Certificate it holds any and all withholding taxes applicable thereto as required by

Law. Borrower agrees (1) whenever any present or future taxes or similar charges are required by applicable Law to be withheld with respect to any amounts payable hereunder or in respect of the Loan Certificates, to withhold such amounts and timely pay the same to the appropriate authority in the name and on behalf of the Lenders, (2) to file any necessary withholding tax returns or statements when due, and (3) as promptly as possible after the payment thereof, to deliver to each Lender appropriate receipts, if reasonably available, showing the payment thereof, together with such additional documentary evidence as any such Lender reasonably requests from time to time. Furthermore, all necessary documentation addressed in Section 2.3(b) hereof shall be furnished to Borrower prior to the due date of any amounts payable by Borrower hereunder to enable such Lender to claim an exemption from, or reduced rate of, such taxes.

(d) Borrower shall not have any liability hereunder to Security Agent or any Lender for Security Agent’s failure to withhold taxes in the manner provided for herein or for any false, inaccurate, or untrue evidence provided by any Lender hereunder.

2.4 Distribution of Funds Received.

(a) All amounts payable hereunder shall be paid to Security Agent for application and distribution as provided herein.

(b) Except as provided in clause (c) below, each payment made by Borrower of the principal of, interest on or other amount in respect of the Loan Certificates shall be distributed by Security Agent as promptly as possible on or after the date that such amount is paid to Security Agent and becomes immediately available to Security Agent:

FIRST, to the payment in full of the aggregate amount of interest due under and Break Loss (if any) and, except as provided in clause “Second” below, all other amounts due under or in respect of the Loan Certificates; and

SECOND, to the payment in full of the unpaid principal amount of the Loan Certificates then due.

(c) After an Event of Default shall have occurred, and so long as such Event of Default shall be continuing and one or more Series of the Loan Certificates have been subject to the provisions of Section 4.1(b) or (c), all payments in respect of the Loan Certificates and all proceeds of any of the Collateral and all other amounts held by Security Agent hereunder shall be distributed in the following order of priority:

FIRST, to the extent not theretofore paid by or on behalf of Borrower, to pay all costs and expenses of Security Agent incurred in connection with the performance of its duties hereunder or under any other Operative Agreement, including reasonable attorneys’ fees and expenses and all costs and expenses incurred by Security Agent in connection with its entering upon, taking possession of, holding, operating, managing, selling or otherwise disposing of the Collateral or any part thereof, any and all Taxes, assessments or other charges of any kind prior to the Lien

of any Operative Agreement that Security Agent determined in good faith to pay or be paid, and all amounts payable to Security Agent hereunder or under any of the Operative Agreements in respect of any indemnities or other obligations of Borrower;

SECOND, to the payment of the unpaid principal amount of, and all accrued and unpaid interest on, all of the Loan Certificates (including Break Loss, if any, and interest on account of overdue payments of principal and interest) and all other Obligations;

THIRD, subject to Section 14 of the Credit Agreement, so much of such payments or amounts remaining to pay in full the other Secured Obligations, whether or not then due (by reason of acceleration or otherwise), in the following order: (1) unpaid principal amount of, and all accrued and unpaid interest on, all Related Notes issued under the Loan Agreement described in clause (b) of the definition of “Loan Agreements” and all other Related Obligations thereto; (2) unpaid principal amount of, and all accrued and unpaid interest on, all Related Notes issued under the Loan Agreement described in clause (a) of the definition of “Loan Agreements” and all other Related Obligations thereto; and (3) all other Secured Obligations, if any; and

FOURTH, the balance, if any, thereof thereafter remaining, to Borrower or such other Person(s) as may then lawfully be entitled thereto.

(d) Distributions among the Loan Certificates shall be made ratably, without priority of one Loan Certificate over another, in accordance with the respective amounts due or unpaid as appropriate to the particular distribution, except for distributions in respect of amounts owing under Section 2.3 or 2.10(b) of this Security Agreement, Sections 3(f), 3(g) or 10 of the Credit Agreement or elsewhere where payments are due to particular Lenders or other Persons, in which event distributions in respect thereof shall be made to the Lender(s) or Person(s) entitled thereto.

2.5 Method of Payment.

The principal amount of, interest on, and other amount due under each Loan Certificate or hereunder will be payable in Dollars by wire transfer of immediately available funds not later than 12:00 Noon, New York time, on the due date of payment to Security Agent for distribution in the manner provided herein. Notwithstanding the foregoing or any provision in any Loan Certificate to the contrary, Security Agent will pay or cause to be paid all amounts to be paid by Borrower hereunder and under any Loan Certificate to the holder thereof (including all amounts distributed pursuant to Section 2.4 of this Security Agreement) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, promptly after receipt to an account maintained by such holder with a bank located in the continental United States the amount to be distributed to such holder, for credit to the account of such holder maintained at such bank. If Security Agent fails to initiate the transfer by federal wire transfer of any such payment as provided in the foregoing sentence after its receipt of funds by reason of its failure to

use ordinary care, Security Agent shall compensate such holders for loss of use of funds at the Applicable Rate until such payment is made, and Security Agent shall be entitled to any interest earned on such funds until such payment is made. Any payment made hereunder shall be made without any presentment or surrender of any Loan Certificate, except that, in the case of the final payment in respect of any Loan Certificate, such Loan Certificate shall be surrendered to Security Agent for cancellation promptly after such payment. Notwithstanding any other provision of this Security Agreement to the contrary, Security Agent shall not be required to make, or cause to be made, wire transfers as aforesaid before the first Business Day on which it is practicable for Security Agent to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:00 Noon, New York time, at the place of payment. Before the due presentment for registration of transfer of any Loan Certificate, Borrower and Security Agent shall deem and treat the Person in whose name any Loan Certificate is registered on the Certificate Register as the absolute owner and holder of such Loan Certificate for the purpose of receiving payment of all amounts payable with respect to such Loan Certificate and for all other purposes, and neither Borrower nor Security Agent shall be affected by any notice to the contrary. So long as any signatory to the Credit Agreement or nominee thereof shall be a registered Lender, all payments and distributions to it shall be made to the account of such Lender specified in Schedule 1 of the Credit Agreement, and otherwise in the manner provided in or pursuant to the Credit Agreement, unless and until it specifies some other account or manner of payment by notice to Security Agent consistent with this Section 2.5.

2.6 [Intentionally Omitted].

2.7 Registration, Transfer and Exchange of Loan Certificates.

Security Agent shall keep a register (the “Certificate Register”) in which Security Agent shall provide for the registration of Loan Certificates and the registration of transfers of Loan Certificates. No such transfer shall be given effect unless and until registered hereunder. Security Agent shall keep the Certificate Register at its Administrative Office. Security Agent is hereby appointed “Certificate Registrar” for the purpose of registering Loan Certificates and transfers of Loan Certificates as herein provided. A holder of any Loan Certificate intending to exchange such Loan Certificate shall surrender such Loan Certificate to Security Agent at its Administrative Office, together with a written request from the registered holder thereof for the issuance of a new Loan Certificate, specifying (in the case of a surrender for transfer) the name(s) and address(es) of the new holder(s). Upon surrender for registration of transfer of any Loan Certificate, Borrower shall execute, and Security Agent shall authenticate and deliver, in the name(s) of the designated transferee(s), one or more new Loan Certificate of a like aggregate original principal amount and Series. At the Lender’s option, Loan Certificates may be exchanged for other Loan Certificates of any authorized denominations of a like aggregate original principal amount and Series, upon surrender of the Loan Certificates to be exchanged to Security Agent at its Administrative Office. Whenever any Loan Certificates are so surrendered for exchange, Borrower shall execute, and Security Agent shall authenticate and deliver, the Loan Certificates which the Lender making the exchange is entitled to receive. All Loan Certificates issued upon any registration of transfer or exchange of Loan Certificates (whether under this Section 2.7 or under Section 2.8 or otherwise under this Security Agreement) shall be the valid obligations of Borrower evidencing the same respective obligations, and entitled to the same security and benefits under this Security Agreement, as the Loan Certificates surrendered

upon such registration of transfer or exchange. Every Loan Certificate presented or surrendered for registration of transfer, shall (if so required by Security Agent) be duly endorsed, or be accompanied by a Transfer Agreement as required under Section 9 of the Credit Agreement in form satisfactory to Security Agent duly executed by the Lender or such holder’s attorney duly authorized in writing. Security Agent shall make a notation on each new Loan Certificate of the amount of principal amounts of Drawings previously made under, and the payments of principal previously made, on the old Loan Certificate or Loan Certificates with respect to which such new Loan Certificate is issued and the date to which interest on such old Loan Certificate or Loan Certificates has been paid. Interest shall be deemed to have been paid on such new Loan Certificate to the date on which interest shall have been paid on such old Loan Certificate, and the principal amounts of Drawings and all payments of the principal marked on such new Loan Certificate, as provided above, shall be deemed to have been made thereon. Security Agent shall not be required to exchange any surrendered Loan Certificates as provided above during the 10-day period preceding the due date of any payment on such Loan Certificate. Borrower and Security Agent shall in all cases deem the Person in whose name any Loan Certificate shall have been issued and registered as the absolute owner and holder of such Loan Certificate for the purpose of receiving payment of all amounts payable by Borrower with respect to such Loan Certificate, and for all other purposes, until Borrower receives from Security Agent a notice stating otherwise and such change is reflected on the Certificate Register. Security Agent will promptly notify Borrower of each registration of a transfer of a Loan Certificate. Subject to compliance by the Lender and its transferee (if any) of the requirements in this Section 2.7, Security Agent and Borrower shall use all reasonable efforts to issue new Loan Certificates upon transfer or exchange within ten (10) Business Days of the date a Loan Certificate is surrendered for transfer or exchange.

2.8 Mutilated, Destroyed, Lost or Stolen Loan Certificates.

If the Loan Certificate being replaced has become mutilated, such Loan Certificate shall be surrendered to Security Agent and a photocopy thereof shall be furnished to Borrower. If the Loan Certificate being replaced has been destroyed, lost, or stolen, the holder of such Loan Certificate shall furnish to Borrower and Security Agent (a) such security or indemnity as they require to save Borrower and Security Agent harmless, and (b) evidence satisfactory to Borrower and Security Agent of the destruction, loss, or theft of such Loan Certificate and of the ownership thereof.

Subject to the Lender’s compliance with the requirements in this Section 2.8, Security Agent and Borrower shall use all reasonable efforts to issue new Loan Certificates within ten (10) Business Days after receiving the Lender’s written request therefor.

4. REMEDIES

4.1 General; Acceleration.

(a) If an Event of Default shall occur and be continuing, the Security Agent, on behalf of the Lenders, may exercise, in addition to all other rights and remedies granted to them in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the New York UCC or any other applicable Law. Without limiting the generality of the foregoing, the Security Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by Law referred to below) to or upon Borrower or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Security Agent or any Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Security Agent or any Lender shall have the right upon any such public sale or sales, and, to the extent permitted by Law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in Borrower, which right or equity of redemption is hereby waived and released. At any public or private sale the Lenders shall be entitled to credit against the purchase price bid at such sale all or any part of the unpaid amounts of Loan Certificates or other Secured Obligations. Borrower further agrees, at the Security Agent’s request, to make the Collateral available to the Security Agent at places which the Security Agent shall reasonably select, whether at Borrower’s premises or elsewhere. The Security Agent shall apply the net proceeds of any action taken by it pursuant to this Section 4.1, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Security Agent and the Lenders hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Secured Obligations, in such order as Security Agent may elect consistent with Section 2.4, and only after such application and after the payment by Security Agent of any other amount required by any provision of Law, need Security Agent account for the surplus, if any, to Borrower. To the extent permitted by applicable Law, Borrower waives all claims, damages and demands it may acquire against the Security Agent or any Lender arising out of the exercise by them of any rights hereunder. Borrower shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay all Obligations.

(b) If an Event of Default referred to in Subsections (d), (e) or (f) of Section 3 shall have occurred, then and in every such case all unfunded Commitments shall be immediately

terminated, the unpaid principal amount of all Loan Certificates then outstanding, together with interest accrued but unpaid thereon, and all other amounts due to the holders of the Loan Certificates thereunder and hereunder and under the other Operative Agreements, shall, unless Security Agent acting upon the instructions of the Majority in Interest of Lenders shall otherwise direct, immediately and without further act become due and payable, without presentment, demand, protest or notice, all of which are hereby waived.

(c) If any other Event of Default shall have occurred and be continuing, then and in every such case, Security Agent, acting upon the instructions of the Majority in Interest of Lenders, may at any time, by written notice or notices to Borrower, (i) terminate the unfunded Commitments in whole or in part (and for purposes of this clause (i) an “Event of Default” shall be determined without regard to Section 14 of the Credit Agreement) and/or (ii) declare all the Loan Certificates of any or all Series to be due and payable, whereupon the unpaid principal amount of such Loan Certificates then outstanding, together with accrued but unpaid interest thereon, and all other amounts due to the Lenders thereunder, hereunder and under the other Operative Agreements, shall immediately and without further act become due and payable without presentment, demand, protest or other notice, all of which are hereby waived.

(d) If the unpaid principal amount of the Loan Certificates of one or more Series shall have become due and payable pursuant to this Section 4.1, there shall also become due and payable to each applicable Lender upon demand, without presentment, protest or notice, all of which are hereby waived, the Break Loss (if any) with respect to such Loan Certificates.

(e) The Security Agent agrees, to the extent permitted at the time by applicable Law, to give to Borrower at least ten (10) days’ prior written revocable notice of any foreclosure of the Lien of this Security Agreement (which period of notice the parties hereto confirm is commercially reasonable).

(f) If an Event of Default shall occur and be continuing, all proceeds of the Collateral received by Borrower consisting of cash, checks and other near-cash items shall be held by Borrower in trust for the Security Agent and the Lenders, segregated from other funds of Borrower, and shall, forthwith upon receipt by Borrower, be turned over to Security Agent in the exact form received by Borrower (duly indorsed by Borrower to Security Agent, if required).

(g) Without limitation of any other provision hereof, Security Agent shall be entitled to take any action, give any notice or exercise any right, power or remedy under and with respect to the Purchase Agreement and the GTA to the extent provided in the Consent and Agreement and in the Engine Consent and Agreement.

4.2 Discontinuance of Proceedings.

If Security Agent institutes any proceeding to enforce any right, power, or remedy under this Security Agreement by foreclosure, entry, or otherwise, and such proceedings is discontinued or abandoned for any reason or is determined adversely to Security Agent, then and in every such case Borrower and Security Agent shall, subject to any determination in such proceedings, be restored to their former positions and rights hereunder with respect to the Collateral, and all rights, remedies, and powers of Borrower or Security Agent shall continue as if no such proceedings had been instituted.

4.3 Waiver of Past Defaults.

Upon written instruction from a Majority in Interest of Lenders, Security Agent shall waive any past Default hereunder and its consequences, and upon any such waiver such Default shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Security Agreement, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon; provided, that in the absence of written instructions from all Lenders, Security Agent shall not waive any Default in respect of a covenant or provision hereof which, under Section 6, cannot be changed without the consent of all Lenders.

4.4 Remedies Cumulative.

Each and every right, power, and remedy given to Security Agent specifically or otherwise in this Security Agreement shall be cumulative and shall be in addition to every other right, power, and remedy herein specifically given or now or hereafter existing at Law, in equity, or by statute, and each and every right, power, and remedy whether specifically herein given or otherwise existing may be exercised from time to time and as often and in such order as Security Agent deems expedient, and the exercise or the beginning of the exercise of any right, power, or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other right, power, or remedy. No delay or omission by Security Agent in the exercise of any right, remedy, or power or in the pursuance of any remedy shall impair any such right, power, or remedy or be construed to be a waiver of any default on the part of Borrower or to be an acquiescence therein.

4.5 Security Agent’s Appointment as Attorney-in-Fact, etc.

(a) Borrower hereby irrevocably constitutes and appoints the Security Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of Borrower and in the name of Borrower or in its own name, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be reasonably necessary to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, Borrower hereby gives the Security Agent the power and right, on behalf of Borrower, without notice to or assent by Borrower, to do any or all of the following:

(i) in the name of Borrower or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due with respect to any Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Security Agent for the purpose of collecting any and all such moneys due with respect to any other Collateral whenever payable;

(ii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Security Agreement and pay all or any part of the premiums therefor and the costs thereof;

(iii) execute, in connection with any sale provided for herein, any indorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; and

(iv) (1) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Security Agent or as the Security Agent shall direct; (2) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (3) sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (4) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (5) defend any suit, action or proceeding brought against Borrower with respect to any Collateral; (6) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Security Agent may deem appropriate; (7) take any action, give any notice or exercise any right, power or privilege under or in respect of the Purchase Agreement or the GTA to the extent permitted in the Consent and Agreement and the Engine Consent and Agreement and (8) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Security Agent were the absolute owner thereof for all purposes, and do, at the Security Agent’s option and Borrower’s expense, at any time, or from time to time, all acts and things which the Security Agent deems reasonably necessary to protect, preserve or realize upon the Collateral and the Security Agent’s and the Lenders’ security interests therein and to effect the intent of this Security Agreement, all as fully and effectively as Borrower might do.

Anything in this Section 4.5(a) to the contrary notwithstanding, the Security Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 4.5(a) unless an Event of Default shall have occurred and be continuing.

(b) If Borrower fails to perform or comply with any of its agreements contained herein, the Security Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The expenses of the Security Agent reasonably incurred in connection with actions undertaken as provided in this Section 4.5, together with interest thereon at the Past Due Rate, from the date of payment by the Security Agent to the date reimbursed by Borrower, shall be payable by Borrower to the Security Agent within ten (10) days following demand.

(d) Borrower hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Security Agreement are coupled with an interest and are irrevocable until this Security Agreement is terminated and the security interests created hereby are released.

4.6 Duty of Security Agent. Security Agent’s sole duty with respect to the custody, safe keeping and physical preservation of the Collateral in its possession, under Section 9-207 of the New York UCC or otherwise, shall be to deal with it in the same manner as the Security Agent deals with similar property for its own account. Subject to mandatory provisions of applicable Law, neither Security Agent, any Lender nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of Borrower or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on Security Agent and the Lenders hereunder are solely to protect Security Agent’s and the Lenders’ interests in the Collateral and, subject to mandatory provisions of applicable Law, (i) such powers shall not impose any duty upon Security Agent or any Lender to exercise any such powers and (ii) Security Agent and the Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers and neither they nor any of their officers, directors, employees or agents shall be responsible to Borrower for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

4.7 Execution of Financing Statements.

Pursuant to any applicable Law, Borrower authorizes the Security Agent to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral without the signature of Borrower in such form and in such offices as are necessary or appropriate to perfect the security interests of the Security Agent under this Security Agreement.

4.8 Authority of Security Agent.

Borrower acknowledges that the rights and responsibilities of the Security Agent under this Security Agreement with respect to any action taken by the Security Agent or the exercise or non-exercise by the Security Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as between the Security Agent and the Lenders, be governed by the Credit Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Security Agent and Borrower, the Security Agent shall be conclusively presumed to be acting as agent for the Lenders with full and valid authority so to act or refrain from acting, and Borrower shall not be under any obligation, or entitlement, to make any inquiry respecting such authority.

5. INVESTMENT OF AMOUNTS HELD BY SECURITY AGENT

Any amounts held by Security Agent pursuant to Section 2.10 or pursuant to any provision of any Operative Agreement providing for amounts to be held by Security Agent which are not distributed pursuant to the other provisions of Section 2.4 shall be invested by

Security Agent from time to time in Cash Equivalents as directed by Borrower so long as Security Agent may acquire them using its reasonable efforts. All Cash Equivalents held by Security Agent pursuant to this Article 5 shall either be (a) registered in the name of, payable to the order of, or specially endorsed to, Security Agent, or (b) held in an Eligible Account. Unless otherwise expressly provided in this Security Agreement, any income realized as a result of any such investment, net of Security Agent’s reasonable fees and expenses in making such investment, shall be held and applied by Security Agent in the same manner as the principal amount of such investment is to be applied, and any losses, net of earnings and such reasonable fees and expenses, shall be charged against the principal amount invested. Security Agent shall not be liable for any loss resulting from any investment required to be made by it under this Security Agreement other than by reason of its willful misconduct or gross negligence, and any such investment may be sold (without regard to its maturity) by Security Agent without instructions whenever such sale is necessary to make a distribution required by this Security Agreement.

Tax Benefits:

(a) any benefits with respect to Taxes which are actually and currently realized by any Tax Indemnitee, which are attributable solely to the incurrence or payment by such Tax Indemnitee of any indemnified Losses or Taxes or an event giving rise to such Losses or Taxes; provided, that for the purpose of calculating such Tax Benefit, such Tax Indemnitee shall be deemed to utilize all other items of income, gain, loss, deduction or credit, including those that arise outside the scope of this Agreement, before utilizing any item arising from the incurrence or payment of any indemnified Loss or Tax. A Tax Indemnitee shall be deemed to have actually and currently realized and utilized a Tax Benefit to the extent that, and at such time as, the amount of Taxes payable by the Tax Indemnitee is actually reduced below the amount of Taxes such Tax Indemnitee would be required to pay but for the incurrence or payment of such Loss or Taxes, computed in accordance with the ordering rules set forth above. Notwithstanding anything to the contrary in this clause (a), in calculating any Tax Benefit, a Tax Indemnitee, to the extent not prohibited by applicable law or by contract, shall determine when Tax Benefits are utilized in a manner which is non-discriminatory with respect to all other Similar Loans, it being understood that if, after taking into account all tax items of such Tax Indemnitee other than from this Loan and Similar Loans, such Tax Indemnitee has the capacity to use some or all of the Tax Benefits and some or all of the tax benefits generated by Similar Loans, it cannot rely upon a provision in such Similar Loan that requires the tax benefits from such Similar Loans to be applied last to avoid applying the tax benefits under those Similar Loans and, based on this non-discriminatory provision, also the Tax Benefits from this Loan in calculating the indemnities due under the respective loan. For purposes of this provision, “Similar Loans” means loans (i) in which the Tax Indemnitee or any affiliate thereof is a participant and with respect to which such Tax Indemnitee or affiliate is entitled to indemnification with respect to Taxes, and (ii) in which the Borrower is a U.S. Borrower with a similar or lesser credit as the Borrower.

(b) The determination of whether the Tax Indemnitee has realized a Tax Benefit and the calculation of the amount of such Tax Benefit shall be made by the Tax Indemnitee in the ordinary course of administering its Tax affairs. Notwithstanding anything to the contrary herein, if the Borrower provides a Tax Indemnitee with a written notice setting forth facts and circumstances which create a reasonable possibility that a Tax Benefit has been realized with respect to an Indemnified Tax, such Tax Indemnitee shall agree to make a determination as to whether it has realized such a Tax Benefit. If a Tax Indemnitee determines that it has realized such a Tax Benefit, it shall pay such Tax Benefit to Borrower in accordance with the terms of Section 10(c)(iv)(5).

Tax Documents: any report, returns, certification, statement or other document related to a Tax.

Transaction Expenses: the reasonable out-of-pocket costs and expenses incurred by Security Agent and each of the Lenders (1) in connection with the preparation, execution, and
