(ii) (i) Each LIBOR Loan shall be in a principal amount of not less than Five Million and 0/100 Dollars ($5,000,000.00) and in an integral multiple of $100,000, (ii) at no time shall there be more than ten (10) tranches of LIBOR Loans outstanding, and (iii) subject to Section 2.8.2, the total aggregate principal amount of all LIBOR Loans outstanding at any one time shall not exceed Borrowing Availability.

(iii) At least three (3) Business Days prior to each Payment Date for a LIBOR Loan, Borrower shall give irrevocable written notice to Lender specifying whether all or a portion of such LIBOR Loan outstanding on the Payment Date (i) is to be repaid and then reborrowed in whole or in part as a new LIBOR Loan, in which case such notice shall also specify the LIBOR Loan Period that Borrower shall have selected for such new LIBOR Loan; provided, that if a Default or Event of Default has occurred and is continuing, Borrower shall not have the option to repay and then reborrow such LIBOR Loan as a new LIBOR Loan, (ii) is to be repaid and then reborrowed in whole or in part as a Base Rate Loan, or (iii) is to be repaid and not reborrowed; provided, that any such reborrowings described in clauses (i) and (ii) above shall be in a principal amount of not less than $5,000,000.00 and in an integral multiple of $100,000. Upon such Payment Date such LIBOR Loan will, subject to the provisions of this Agreement, be so repaid and, as applicable, reborrowed.

2.1.4 Request and Disbursement. Administrative Agent shall, upon the reasonable request of Borrower from time to time, provide to Borrower such information with regard to the LIBOR Basis as Borrower may request. Promptly following receipt of a request for a Loan, Administrative Agent shall notify each Lender by telephone or telecopier (and if by telephone, promptly confirmed by telecopier) of the date and type of Loan, the applicable LIBOR Loan Period, and that Lender’s Pro Rata Share of the Loan. Not later than 10:00 a.m., California time, on the date specified for any Loan (which must be a Business Day), each Lender shall make its Pro Rata Share of the Loan in immediately available funds available to Administrative Agent at Administrative Agent’s office. Prior to 11:00 a.m. (California time) on the date of a Revolving Loan, Administrative Agent shall, subject to the satisfaction of the conditions set forth in Section 2.2, disburse the amount of the requested Revolving Loan by deposit into the Demand Deposit Account or by wire transfer pursuant to Borrower’s written instructions.

2.2 Swing Line Loans.

2.2.1 Swing Line Commitment. The Swing Line Lender shall from time to time from the Closing Date through the day prior to the Maturity Date make loans to Borrower in such amounts as Borrower may request, up to an aggregate maximum amount of $15,000,000.00 (each, a “Swing Line Loan”), provided that (a) if after giving effect to such Swing Line Loan, the sum of the aggregate principal amount of all then outstanding Loans does not exceed the Borrowing Availability at such time; and (b) without the consent of all of the

Lenders, no Swing Line Loan may be made during the continuation of an Event of Default, provided written notice of such Event of Default shall have been provided to Swing Line Lender by Administrative Agent or a Lender sufficiently in advance of the making of such Swing Line Loan.

2.2.2 Request for Swing Line Loan. Borrower may borrow, repay and reborrow under the Swing Line Commitment, subject to the remaining availability under the Swing Line Commitment and subject to availability under the Revolving Commitment, upon telephonic request by an Authorized Signatory of Borrower made to Administrative Agent not later than 2:00 p.m., California time, on the Business Day of the requested borrowing (which telephonic request shall be promptly confirmed in writing by telecopier or electronic mail). Promptly after receipt of such a request for borrowing, Administrative Agent shall provide telephonic verification to the Swing Line Lender that, after giving effect to such request, availability under the Swing Line Commitment and the Revolving Commitment will exist (and such verification shall be promptly confirmed in writing by telecopier or electronic mail). Borrower shall notify the Swing Line Lender of its intention to make a repayment of a Swing Line Loan not later than 1:00 p.m. California time on the date of repayment. If Borrower instructs the Swing Line Lender to debit its Demand Deposit Account in the amount of any payment with respect to a Swing Line Loan, or the Swing Line Lender otherwise receives repayment, after 3:00 p.m., California time, on a Business Day, such payment shall be deemed received on the next Business Day. The Swing Line Lender shall promptly notify Administrative Agent of the Swing Line Loan outstanding each time there is a change therein.

2.2.3 Swing Line Interest Rate. Swing Line Loans shall bear interest at a fluctuating all-in rate (commensurate with a market rate of interest at the time of funding) per annum as quoted by Swing Line Lender to Borrower at the time a Swing Line Loan is requested by Borrower. Interest shall be payable monthly on such dates as may be specified by the Swing Line Lender and in any event on the Maturity Date. The Swing Line Lender shall be responsible for invoicing Borrower for such interest. The interest payable on Swing Line Loans is solely for the account of the Swing Line Lender (subject to Section 2.2.5 below).

2.2.4 Swing Line Maturity Date. Subject to Section 2.2.6 below, the principal amount of all Swing Line Loans shall be due and payable on the earlier of (i) the maturity date agreed to by the Swing Line Lender and Borrower with respect to such loan or (ii) the Maturity Date.

2.2.5 Swing Line Participation. Upon the making of a Swing Line Loan, each Lender shall be deemed to have purchased from the Swing Line Lender a participation therein in an amount equal to that Lender’s Pro Rata Share times the amount of the Swing Line Loan. Upon demand made by the Swing Line Lender, which shall occur not more than once per week, each Lender shall, according to its Pro Rata Share, promptly provide to the Swing Line Lender its

purchase price therefor in an amount equal to its participation therein. The obligation of each Lender to so provide its purchase price to the Swing Line Lender shall be absolute and unconditional (except for modifications or demand made by the Swing Line Lender) and shall not be affected by the existence of an uncured Event of Default; provided that no Lender shall be obligated to purchase its Pro Rata Share of (i) the Swing Line Loans to the extent that, after giving effect to such Swing Line Loan, advances under the Revolving Commitment exceed the Borrowing Availability, (ii) Swing Line Loans to the extent that, after giving effect to such Swing Line Loan, the aggregate amount of Swing Line Loans outstanding exceed $15,000,000.00, or (iii) any Swing Line Loan made (absent the consent of all of the Lenders) during the continuation of an Event of Default if written notice of such Event of Default shall have been provided to Swing Line Lender by Administrative Agent or a Lender sufficiently in advance of the making of such Swing Line Loan. Each Lender that has provided to the Swing Line Lender the purchase price due for its participation in Swing Line Loans shall thereupon acquire a pro rata participation, to the extent of such payment, in the claim of the Swing Line Lender against Borrower for principal and interest and shall share, in accordance with that pro rata participation, in any principal payment made by Borrower with respect to such claim and in any interest payment made by Borrower (but only with respect to periods subsequent to the date such Lender paid the Swing Line Lender its purchase price) with respect to such claim.

2.2.6 Swing Line Repayment; Revolving Loans. The Swing Line Lender may, at any time, in its sole discretion, by not less than two Business Days’ prior written notice to Borrower and Lenders, demand payment of the Swing Line Loans by way of a Revolving Loan in the full amount or any portion of the outstanding amount of Swing Line Loans. In each case, Administrative Agent shall automatically provide the advances made by each Lender to the Swing Line Lender (which the Swing Line Lender shall then apply to the outstanding amount of the Swing Line Loans). In the event that Borrower fails to request a Revolving Loan within the time specified by this Section 2.2.6 on any such date, Administrative Agent may, but is not required to, without notice to or the consent of Borrower, cause Base Rate Loans to be made by the Lenders under the Revolving Commitment in amounts which are sufficient to reduce the outstanding amount of the Swing Line Loans as required above. The proceeds of such advances shall be paid directly to the Swing Line Lender for application to the outstanding amount of the Swing Line Loans.

2.3 Letters of Credit.

2.3.1 As a sublimit under the Revolving Commitment, Issuing Lender agrees, subject to the terms and conditions hereof, from time to time from the Closing Date through the Maturity Date to issue Letters of Credit for the account of Borrower; provided, however, that the form and substance of each Letter of Credit shall be subject to approval by Issuing Lender, in its sole discretion; and provided further that after giving effect to all such Letters of

Credit, (i) the sum of the aggregate principal amount of all then-outstanding Loans does not exceed the Borrowing Availability and (ii) the Aggregate Effective Amount under all outstanding Letters of Credit does not exceed Fifteen Million and 00/100 Dollars ($15,000,000). Each Letter of Credit shall mature fifteen (15) days prior to the Maturity Date, and unless the Requisite Lenders otherwise consent in a writing delivered to Administrative Agent, the term of any Letter of Credit shall not exceed one (1) year or extend beyond the Maturity Date, provided that in the Requisite Lenders’ discretion, Letters of Credit may mature after the Maturity Date provided Borrower agrees to deposit cash with Issuing Lender in the amount of such Letter of Credit at least fifteen (15) days prior to the Maturity Date in order to secure such outstanding Letter of Credit obligations. Each Letter of Credit shall be subject to the additional terms and conditions of Issuing Lender’s standard agreement for a Letter of Credit-and related documents, if any, required by Issuing Lender in connection with the issuance thereof. If for any reason advances under the Revolving Commitment are not available at the time any draft is paid by Lender, then Borrower shall immediately pay to Issuing Lender the full amount of such draft, together with interest thereon from the date such amount is paid by Issuing Lender to the date such amount is fully repaid by Borrower, at the Base Rate of interest applicable to the unpaid principal under the Loans.

2.3.2 Each Request for Letter of Credit shall be submitted to Issuing Lender, with a copy to Administrative Agent, at least two (2) Business Days prior to the date upon which the related Letter of Credit is proposed to be issued. Administrative Agent shall promptly notify Issuing Lender whether such Request for Letter of Credit, and the issuance of a Letter of Credit pursuant thereto, conforms to the requirements of this Agreement. Upon issuance of a Letter of Credit, Issuing Lender shall promptly notify Administrative Agent, and Administrative Agent shall promptly notify the Lenders, of the amount and terms thereof.

2.3.3 Upon the issuance of a Letter of Credit, each Lender shall be deemed to have purchased a pro rata participation in such Letter of Credit from Issuing Lender in an amount equal to that Lender’s Pro Rata Share. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that Issuing Lender has not been reimbursed by Borrower for any payment required to be made by Issuing Lender under any Letter of Credit, each Lender shall, pro rata according to its Pro Rata Share, reimburse Issuing Lender through Administrative Agent promptly upon demand for the amount of such payment. The obligation of each Lender to so reimburse Issuing Lender shall be absolute and unconditional and shall not be affected by the occurrence of an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of Borrower to reimburse Issuing Lender for the amount of any payment made by Issuing Lender under any Letter of Credit together with interest as hereinafter provided.

2.3.4 Borrower agrees to pay to Issuing Lender through Administrative Agent an amount equal to any payment made by Issuing Lender with respect to each Letter of Credit within one (1) Business Day after demand made by Issuing Lender therefor, together with interest at the Base Rate plus the Applicable Base Rate Margin on such amount from the date of any payment made by Issuing Lender at the rate applicable to Base Rate Loans for two (2) Business Days and thereafter at the Default Rate applicable to Base Rate Loans. The principal amount of any such payment shall be used to reimburse Issuing Lender for the payment made by it under the Letter of Credit and, to the extent that the Lenders have not reimbursed Issuing Lender pursuant to Section 2.3.3, the interest amount of any such payment shall be for the account of Issuing Lender. Each Lender that has reimbursed Issuing Lender pursuant to Section 2.3.3 for its Pro Rata Share of any payment made by Issuing Lender under a Letter of Credit shall thereupon acquire a pro rata participation, to the extent of such reimbursement, in the claim of Issuing Lender against Borrower for reimbursement of principal and interest under this Section 2.3.4 and shall share, in accordance with that pro rata participation, in any principal payment made by Borrower with respect to such claim and in any interest payment made by Borrower (but only with respect to periods subsequent to the date such Lender reimbursed Issuing Lender) with respect to such claim.

2.3.5 Borrower may request that a Revolving Loan be made to provide funds for the payment required by Section 2.3.4. The proceeds of such Revolving Loan shall be paid directly to Issuing Lender to reimburse it for the payment made by it under the Letter of Credit.

2.3.6 If Borrower fails to make the payment required by Section 2.3.4 within the time period therein set forth, in lieu of the reimbursement to Issuing Lender under Section 2.3.3, Issuing Lender may (but is not required to), without notice to or the consent of Borrower, instruct Administrative Agent to cause Revolving Loans to be made by the Lenders under the Revolving Commitment in an aggregate amount equal to the amount paid by Issuing Lender with respect to that Letter of Credit. The proceeds of such Loans shall be paid directly to Issuing Lender to reimburse it for the payment made by it under the Letter of Credit.

2.3.7 The issuance of any supplement, modification, amendment, renewal, or extension to or of any Letter of Credit shall be treated in all respects the same as the issuance of a new Letter of Credit.

2.3.8 The obligation of Borrower to pay to Issuing Lender the amount of any payment made by Issuing Lender under any Letter of Credit shall be absolute, unconditional, and irrevocable, subject only to performance by Issuing Lender of its obligations to Borrower under Uniform Commercial Code Section 5-109. Without limiting the foregoing, Borrower’s obligations shall not be affected by any of the following circumstances:

(i) any lack of validity or enforceability prior to its stated expiration date of the Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

(ii) any amendment or waiver of or any consent to departure from the Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

(iii) the existence of any claim, setoff, defense, or other rights which Borrower may have at any time against Issuing Lender, Administrative Agent or any Lender, any beneficiary of the Letter of Credit (or any persons or entities for whom any such beneficiary may be acting) or any other Person, whether in connection with the Letter of Credit, this Agreement, or any other agreement or instrument relating thereto, or any unrelated transactions;

(iv) any demand, statement, or any other document presented under a Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever so long as any such document appeared substantially to comply with the terms of such Letter of Credit and provided Issuing Lender did not act with gross negligence or willful misconduct in accepting such document;

(v) payment by Issuing Lender in good faith under a Letter of Credit against presentation of a draft or any accompanying document which does not strictly comply with the terms of the Letter of Credit and provided Issuing Lender did not act with gross negligence or willful misconduct in accepting such document;

(vi) the existence, character, quality, quantity, condition, packing, value or delivery of any property purported to be represented by documents presented in connection with any Letter of Credit or any difference between any such property and the character, quality, quantity, condition, or value of such property as described in such documents;

(vii) the time, place, manner, order or contents of shipments or deliveries of property as described in documents presented in connection with any Letter of Credit or the existence, nature and extent of any insurance relative thereto;

(viii) the solvency or financial responsibility of any party issuing any documents in connection with a Letter of Credit, except for Issuing Lender;

(ix) any failure or delay in notice of shipments or arrival of any property;

(x) any error in the transmission of any message relating to a Letter of Credit not caused by Issuing Lender, or any delay or interruption in any such message;

(xi) any error, neglect or default (other than gross negligence or willful misconduct) of any correspondent of Issuing Lender in connection with a Letter of Credit;

(xii) any consequence arising from acts of God, war, insurrection, civil unrest, disturbances, labor disputes, emergency conditions or other causes beyond the control of Issuing Lender; and

(xiii) so long as Issuing Lender in good faith determines that the contract or document appears substantially to comply with the terms of the Letter of Credit, the form, accuracy, genuineness or legal effect of any contract or document referred to in any document submitted to Issuing Lender in connection with a Letter of Credit.

(xiv) The Uniform Customs and Practice for Documentary Credits, as published in its most current version by the International Chamber of Commerce, shall be deemed a part of this Section 2.3.8 and shall apply to all Letters of Credit to the extent not inconsistent with Applicable Law.

2.4 Payment of Interest; Interest Rate.

2.4.1 Loans. Interest on Revolving Loans and Swing Line Loans shall be payable as follows:

(i) Base Rate Loans. Interest on each outstanding Base Rate Loan shall be computed for the actual number of days elapsed on the basis of a year of 360 days and shall be payable to Administrative Agent for the ratable benefit of Lenders, in arrears (i) on the first Business Day of each month, (ii) on the Maturity Date, and (iii) if any interest accrues or remains payable after the Maturity Date or during the continuance of an Event of Default, upon demand by Administrative Agent. Interest shall accrue and be payable on each Base Rate Loan at a per annum interest rate equal to the Base Rate plus the Applicable Base Rate Margin (“Applicable Base Rate”). The Base Rate shall be equal to the highest of (i) the rate of interest most recently announced by Administrative Agent as to its U.S. dollar “Reference Rate”, (ii) the Federal Funds Rate plus one-half of one percent (0.50%) or (iii) one month LIBOR plus one and one half percent (1.50%).

(ii) LIBOR Loans. Interest on each outstanding LIBOR Loan shall be computed for the actual number of days elapsed on the basis of a year of 360 days and shall be payable to Administrative Agent, for the ratable benefit of Lenders, in arrears (i) on the last day of the applicable LIBOR Loan Period in the case of any LIBOR Loan with a LIBOR Loan Period of one, two or three months, (ii) on the 90th day and the last day of the applicable LIBOR Loan Period in the case of any LIBOR Loan with a LIBOR Loan Period greater than three months, (iii) on the Maturity Date, and (iv) if any interest accrues or remains payable after the Maturity Date or during the continuance of an Event of Default, upon demand by Administrative Agent. Interest shall accrue and be payable on each LIBOR Loan at a per annum interest rate equal to the LIBOR Basis applicable to such LIBOR Loan plus the Applicable LIBOR Margin (“Applicable LIBOR Rate”).

(iii) Applicable Margins and Fees. The Applicable Base Rate Margin, the Applicable LIBOR Margin, and Applicable Unused Line Fee Percentage shall be determined based on the Leverage Ratio as reported in the most recent Compliance Certificate (delivered to Administrative Agent pursuant to Section 8) by reference to Table 1 below:

Table 1

Level	Leverage Ratio	Applicable Base Rate Margin	Applicable LIBOR Margin	Applicable Unused Line Fee Percentage
I	<3.0	1.50%	3.00%	0.65%
II	>3.0 but less than 3.5	2.00%	3.50%	0.75%
III	>3.5 but less than 4.0	2.50%	4.00%	1.00%
IV	>4.0	3.00%	4.50%	1.25%

Notwithstanding the foregoing, Level II rates shall apply for all Loans made from the Closing Date until Administrative Agent has received a Compliance Certificate, satisfactory in form and substance to Administrative Agent, for Borrower’s Fiscal Quarter ending December 31, 2009.

2.4.2 Default Rate. Upon the occurrence and during the continuance of an Event of Default, interest on all outstanding Obligations shall, upon the election of Administrative Agent (acting at the direction of the Requisite Lenders), confirmed by written notice from Administrative Agent to Borrower, accrue and be payable at the Default Rate; provided, however, that the Default Rate shall not apply to any Letter of Credit Obligations unless such Letter of Credit Obligations are not paid when due by Borrower under this Agreement. Interest accruing at the Default Rate shall be payable to Administrative Agent, for the ratable benefit of Lenders, on demand and in any event on the Maturity Date. Administrative Agent shall not be required to (1) accelerate the maturity of the Loans or (2) exercise any other rights or remedies under the Loan Documents, in order to charge the Default Rate. Upon the occurrence and during the continuance of an Event of Default specified in Sections 9.1.5, 9.1.6, or 9.1.7, the interest rate shall be increased automatically to the Default Rate without the necessity of any action by Administrative Agent.

2.5 Maximum Rate of Interest. In no event shall the aggregate of all interest on the Obligations charged or collected pursuant to the terms of this Agreement or pursuant to the Notes exceed the highest rate permissible under any law that a court of competent jurisdiction shall, in a final determination, deem applicable. In the event that such a court determines that a Lender has charged or received interest under this Agreement or the Notes in excess of the highest applicable rate, the rate in effect under this Agreement and the Notes shall automatically be reduced to the maximum rate permitted by Applicable Law and Lender shall promptly apply such excess to reduce the principal balance of the Obligations, or if the principal balance of the Obligations owing have been paid in full, Lender shall promptly apply such excess to reduce any other Obligations, and if all Obligations have been paid in full, then Lender shall refund to Borrower any interest received by Lender in excess of the maximum lawful rate; provided, that if at any time thereafter the rate of interest payable hereunder is less than the highest applicable rate, Borrower shall continue to pay interest hereunder at the highest applicable rate, until such time as the total interest received by Lender from the making of Loans hereunder is equal to the total interest that Lender would have received had the interest rate payable hereunder been (but for the operation of this Section 2.5) the interest rate payable since the Closing Date as otherwise provided in this Agreement. It is the intent of this Agreement that Borrower not pay or contract

to pay, and that Lender not receive or contract to receive, directly or indirectly, interest in excess of that which may be paid by Borrower under Applicable Law.

2.6 Fees. Borrower shall pay to Administrative Agent:

2.6.1 Unused Line Fee. The Unused Line Fee for the ratable benefit of Lenders commencing as of the Closing Date, payable quarterly in arrears, commencing on the first Business Day of the Fiscal Quarter beginning January 1, 2010, and ending on the Termination Date. The Unused Line Fee shall be, for each day after the Closing Date through the Maturity Date, an amount equal to (a) the difference between (1) the Maximum Amount, and (2) the closing balance of the Loans for such day, multiplied by (b) the Applicable Unused Line Fee Percentage, the product of which is then divided by (c) 360. Notwithstanding the foregoing, no Unused Line Fee shall be paid by Borrower for the benefit of any Defaulting Lender for each day that such Lender remains a Defaulting Lender; provided, an Unused Line Fee shall continue to accrue for the ratable benefit of all Non-Defaulting Lenders for such time period and an Unused Line Fee shall accrue as to the previously Defaulting Lender upon the date that such Lender becomes a Non-Defaulting Lender.

2.6.2 Letter of Credit Fees.

(i) Letter of Credit fee(s) payable to Administrative Agent for the account of Issuing Lender in an amount equal to (i) 25 basis points (0.25%) per annum on the undrawn face amount of each Letter of Credit together with all other standard and customary fees of Issuing Lender in connection with the Letters of Credit, including those fees provided for in any Letter of Credit application agreement to be entered into between Issuing Lender and Borrower and Issuing Lender’s regulations, interpretations and published schedule of fees in connection with the Letters of Credit, which fee(s) are payable on the date of issuance of each such Letter of Credit for the first year and payable annually thereafter as invoiced by Issuing Lender, and (ii) upon the payment or negotiation by Issuing Lender of each draft under any Letter of Credit and upon the occurrence of any other activity with respect to any Letter of Credit (including without limitation, the transfer, amendment or cancellation of any Letter of Credit) such fees and charges determined in accordance with Issuing Lender’s standard fees and charges then in effect for such activity, payable as invoiced by Issuing Lender.

(ii) A per annum standby letter of credit fee payable to Administrative Agent for the ratable benefit of each Lender, in an amount equal to the then Applicable LIBOR Margin multiplied by the undrawn face amount of each standby Letter of Credit, payable quarterly in arrears (i) on the first Business Day of each Fiscal Quarter and (ii) on the Maturity Date.

2.6.3 Fees to Administrative Agent. On the Closing Date and on each other date upon which a fee is payable, Borrower shall pay to Administrative Agent such fees as heretofore agreed upon by letter agreement dated as of May 7, 2009, between Borrower and Union Bank, N.A., as

Administrative Agent, which fees shall be solely for its own account and are nonrefundable.

2.7 Late Payments. If any installment of principal or interest or any fee or cost or other amount payable under any Loan Document to any Lender, Issuing Lender, or Swing Line Lender is not paid when due, it shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate, to the fullest extent permitted by Applicable Laws.

2.8 Repayment and Prepayment.

2.8.1 Repayment and Voluntary Prepayment. Borrower shall pay the principal balance of the Loans and all other Obligations in full on the Maturity Date. The principal amount of any Base Rate Loan may be prepaid prior to the Maturity Date at any time; provided, that any such prepayments shall be in minimum amounts to be agreed upon by Administrative Agent and Borrower. The principal amount of any LIBOR Loan together with all accrued and unpaid interest thereon may be prepaid prior to the applicable Payment Date, together with any breakage fees as set forth in Section 2.8.5, upon three (3) Business Days’ prior notice to Lender. Each notice of prepayment shall be irrevocable.

2.8.2 Overadvances. Borrower shall immediately repay to Administrative Agent, for the ratable benefit of Lenders, any Overadvance. Overadvances constitute Obligations that are evidenced by the Revolving Note, secured by the Collateral, and entitled to all of the benefits of the Loan Documents.

2.8.3 Mandatory Prepayment. Within three (3) Business Days of receiving written notice from Administrative Agent of the occurrence of any Borrowing Base Deficiency or Appraisal Deficiency, Borrower shall repay all or such portion of the Loans in an amount equal to such deficiency, together with any breakage fees as set forth in Section 2.8.5; provided, however, that with respect to an Appraisal Deficiency which is the result of a new or updated appraisal, the foregoing cure period shall be extended to be sixty (60) days.

2.8.4 Mandatory Repayment. Upon the occurrence of a Change in Control, the Revolving Commitment shall be terminated, and all outstanding Loans shall be repaid in full, together with any breakage fees as set forth in Section 2.8.5.

2.8.5 Breakage Fees. Upon payment or prepayment of any LIBOR Loan (other than as the result of a conversion required under Section 15.1.3) on a day other than the last day in the applicable LIBOR Loan Period (whether voluntarily, involuntarily, by reason of acceleration, or otherwise), or upon the failure of Borrower (for a reason other than the breach by a Lender of its obligation to make a LIBOR Loan pursuant to this Agreement) to borrow on the date or in the amount specified for a LIBOR Loan in any Notice of Borrowing, Borrower shall pay to Lender within five (5) Business Days after

demand a prepayment fee or failure to borrow fee, as the case may be (determined based on 100% of the LIBOR Loan actually funded in the London Eurodollar Market (the “Designated Eurodollar Market”)) equal to the sum of:

(i) $250; plus

(ii) the amount, if any, by which (i) the additional interest would have accrued on the amount prepaid or not borrowed at the LIBOR Basis exceeds (ii) the interest Lenders could recover by placing such amount on deposit in the Designated Eurodollar Market for a period beginning on the date of the prepayment or failure to borrow and ending on the last day of the applicable LIBOR Loan Period (or, if no deposit rate quotation is available for such period, for the most comparable period for which a deposit rate quotation may be obtained); plus

(iii) all out-of-pocket expenses incurred by Lenders directly attributable to such payment, prepayment or failure to borrow.

Each Lender making a claim under this Section shall submit to the Borrower an itemized and substantiated statement setting forth such Lender’s accounting of the amount of any prepayment fee payable under this Section, which calculation shall, absent manifest error, be deemed final, binding and conclusive upon Borrower, unless Borrower, within thirty (30) days after the date any such accounting is rendered, provides such Lender with written notice of any objection which Borrower may have to such accounting.

2.9 Term. The Credit Facilities shall be in effect until the Maturity Date. The Credit Facilities and all other Obligations related thereto shall be automatically due and payable in full on the Maturity Date, unless earlier due and payable or terminated as provided in this Agreement.

2.10 Early Termination. The Credit Facilities may be terminated, in whole or in increments of $10,000,000.00, by Borrower prior to the Maturity Date upon five (5) Business Days’ prior written notice to Administrative Agent; provided, that at such time Borrower shall (a) prepay all amounts outstanding under the Credit Facilities which exceed the reduced Revolving Commitment amount elected by Borrower, (b) cause the outstanding Letters of Credit to be canceled and returned to Lenders or provide Lenders with a standby letter of credit or collateral therefor, acceptable to Issuing Lender and/or Lenders in its/their sole discretion if such outstanding Letters of Credit would cause the amounts outstanding under the Credit Facilities to exceed the reduced Revolving Commitment amount elected by Borrower, (c) pay all accrued interest thereon and fees and charges incurred in connection therewith, and (d) reimburse Lenders for those costs and expenses incurred by Lenders in connection with such prepayment and termination, as set forth in Section 2.8.5.

2.11 Note and Accounting. Administrative Agent shall provide a quarterly accounting to Borrower of the Loans and Letter of Credit Obligations and other transactions under this Agreement, including Administrative Agent’s calculation of principal and interest. Each and every such accounting shall, absent manifest error, be deemed final, binding and conclusive upon Borrower, unless Borrower, within thirty (30) days after the date any such accounting is rendered, provides Administrative Agent with written notice of any objection which Borrower

may have to any item in such accounting, describing the basis for such objection with specificity. In that event, only those items expressly objected to in such notice shall be deemed to be disputed by Borrower, and in the event the parties cannot resolve their dispute, such dispute shall be resolved in accordance with the terms and conditions of the Alternative Dispute Resolution Agreement.

2.12 Manner of Payment.

2.12.1 When Payments Due.

(i) Except as expressly set forth in this Agreement, each payment (including any prepayment) by Borrower on account of the principal of or interest on the Loans and any other amount owed to Lenders on account of the Obligations shall be made not later than 11:00 a.m. (California time) on the date specified for payment under this Agreement to Administrative Agent in lawful money of the United States and in immediately available funds. Any payment received by Administrative Agent on a day that is not a Business Day or after 11:00 a.m. (California time) on a Business Day, shall be deemed received on the next Business Day. The amount of all payments received by Administrative Agent for the account of each Lender shall be immediately paid by Administrative Agent to the applicable Non-Defaulting Lender in immediately available funds and, if such payment was received by Administrative Agent by 11:00 a.m., California time, on a Business Day and not so made available to the account of a Lender on that Business Day, Administrative Agent shall reimburse that Lender for the cost to such Lender of funding the amount of such payment at the Federal Funds Rate. The amount of all payments received by the Administrative Agent for the account of any Defaulting Lender shall be held in trust by the Administrative Agent for the benefit of such Defaulting Lender until such time as such Defaulting Lender shall cease to be a Defaulting Lender under this Agreement, at which time, the Administrative Agent shall pay over such amounts (without interest) to such Lender. All payments shall be made in lawful money of the United States of America.

(ii) If any payment on any Obligation is specified to be made upon a day that is not a Business Day, it shall (subject to the provisions of the LIBOR Loan Period which may require payment by one (1) earlier Business Day) be deemed to be specified to be made on the next succeeding day that is a Business Day, and such extension of time shall in such case be included in computing interest and fees, if any, in connection with such payment.

2.12.2 No Deductions. Subject to Section 2.12.1(a) above, Borrower shall pay principal, interest, fees, and all other amounts due on the Obligations without set-off or counterclaim or any deduction whatsoever.

2.12.3 Inadequate Payments. If, on the date on which any amount (including any payment of principal, interest or other costs and expenses) shall be due and payable by Borrower to Credit Facility Lenders, the amount received by any such Lenders from Borrower shall not be adequate to pay the entire amount then due and payable, then Administrative Agent shall be authorized, but shall not be obligated, to make a Base Rate Loan to Borrower in the amount of the deficiency.

2.13 Application of Payments. Borrower irrevocably waives the right to direct the application of any and all payments received at any time by any Credit Facility Lender from or on behalf of Borrower and specifically waives any provisions of the law of the State of New York or any other Applicable Law giving Borrower the right to designate application of payments. All amounts received by Administrative Agent for application to the Obligations shall be applied by Administrative Agent in the following order of priority: (i) to the payment of any fees then due and payable, (ii) to the payments of all other amounts not otherwise referred to in this Section 2.13 then due and payable hereunder or under the other Loan Documents (including any costs and expenses incurred by Administrative Agent as a result of a Default or an Event of Default), (iii) to the payment of interest then due and payable on the Loans, and (iv) to the payment of principal then due and payable on the Loans. Notwithstanding the foregoing, Borrower irrevocably agrees that, during the occurrence of an Event of Default, Credit Facility Lenders shall have the continuing exclusive right to determine the order and method of the application of payments against the then due and payable Obligations of Borrower in each of the Credit Facility Lenders’ sole discretion and to revise such application prospectively or retroactively in Credit Facility Lenders’ sole discretion; provided that all proceeds of Collateral shall be distributed pari passu to the Credit Facility Lender and Non-Lenders.

2.14 Use of Proceeds. The proceeds of the Loans shall be used by Borrower for general corporate purposes, including financing aircraft engines owned and held for lease and the purchase of Parts.

2.15 All Obligations to Constitute One Obligation. All Obligations related to the Credit Facilities constitute one general obligation of Borrower and shall be secured by Security Agent’s Liens upon all of the Collateral, and by all other Liens previously, now or at any time in the future granted by Borrower to Security Agent, Administrative Agent, any Credit Facility Lender or any Non-Lender to the extent provided in the Collateral Documents and permitted by this Agreement.

2.16 Authorization to Make Loans. Administrative Agent, Lender, Swing Line Lender, and Issuing Lender (each, an “Authorized Party”) are authorized to make the Loans based on telephonic or other oral or written instructions received from any Person that an Authorized Party believes in good faith to be an authorized representative of Borrower, or at the discretion of such Authorized Party, if such Loans are necessary to satisfy any of the Obligations. Borrower consents to the recordation of any telephonic or other communications between an Authorized Party and Borrower for the purpose of maintaining such party’s business records of such transactions.

2.17 Authorization to Debit Accounts. Borrower authorizes each Authorized Party, upon prior notice to Borrower, to debit any of Borrower’s bank accounts with such party for the purpose of Borrower’s payment of principal, interest or other costs and expenses due and payable by Borrower to Lenders under this Agreement.

2.18 Administrative Agent’s Right to Assume Funds Available for Revolving Loans. Unless Administrative Agent shall have been notified by any Lender no later than 10:00 a.m. on the Business Day of the proposed funding by Administrative Agent of any Revolving Loan that such Lender does not intend to make available to Administrative Agent such Lender’s portion of

the total amount of such Revolving Loan, Administrative Agent may assume that such Lender has made such amount available to Administrative Agent on the date of the Revolving Loan and Administrative Agent may, in reliance upon such assumption, make available to Borrower a corresponding amount. If Administrative Agent has made funds available to Borrower based on such assumption and such corresponding amount is not in fact made available to Administrative Agent by such Lender, Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender. If such Lender does not pay such corresponding amount forthwith upon Administrative Agent’s demand therefor, Administrative Agent promptly shall notify Borrower and Borrower shall either (i) pay such corresponding amount to Administrative Agent or (ii) arrange for another Lender or Lenders to assume the Defaulting Lender’s commitment to pay such corresponding amount and such assuming Lender(s) shall pay the corresponding amount to Administrative Agent (upon which payment the Defaulting Lender’s and any such assuming Lender’s Pro Rata Share shall be adjusted accordingly). Administrative Agent also shall be entitled to recover from such Defaulting Lender interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by Administrative Agent to Borrower to the date such corresponding amount is recovered by Administrative Agent, at a rate per annum equal to the daily Federal Funds Rate. Nothing herein shall be deemed to relieve any Lender from its obligation to fulfill its share of the Revolving Commitment or to prejudice any rights which Administrative Agent or Borrower may have against any Lender as a result of any default by such Lender hereunder.

2.19 Optional Increase to the Revolving Commitment.

2.19.1 Provided that no Default or Event of Default then exists, Borrower may elect, from time to time, on or after the Closing Date, in writing, that the then effective Revolving Commitment be increased up to an aggregate amount which is not in excess of Three Hundred Million and 00/100 Dollars ($300,000,000.00). Any request under this Section 2.19 shall be submitted by Borrower to Lenders through Administrative Agent not less than thirty (30) days prior to the proposed increase, specify the proposed effective date and amount of such increase, and be accompanied by (i) a certificate signed by an Authorized Signatory, stating that no Default or Event of Default exists as of the date of the request or will result from the requested increase and (ii) an updated Appraisal of the Collateral satisfactory to Administrative Agent, in its sole and absolute discretion. Any such request shall be approved by Administrative Agent if Borrower provides the foregoing items and Administrative Agent receives sufficient commitments from Lenders pursuant to Sections 2.19.2 through 2.19.4 to fund the requested increase.

2.19.2 Borrower shall be solely responsible for requesting a commitment from each Lender to assume a portion of the proposed increase to the Revolving Commitment, and Borrower shall copy Administrative Agent on all such requests. Each Lender may approve or reject such request in its sole and absolute discretion, and any Lender who fails to send an affirmative written response to Borrower, with a copy to Administrative Agent, within ten (10) Business Days after receipt of such request, shall be deemed to have rejected Borrower’s request.

2.19.3 In responding to a request under this Section, each Lender which is willing to assume a portion of the proposed increase to the Revolving Commitment shall specify the amount of the proposed increase that it is willing to assume. Each consenting Lender shall be entitled to participate ratably (based on its Pro Rata Share of the Revolving Commitment before such increase) in any resulting increase in the Revolving Commitment, subject to the right of Administrative Agent to adjust allocations of the increased Revolving Commitment so as to result in the amounts of the Pro Rata Shares of the Lenders being in integral multiples of $100,000.00.

2.19.4 If the aggregate principal amount offered to be assumed by the consenting Lenders is less than the amount requested, Borrower may (i) reject the proposed increase in its entirety, (ii) accept the offered amounts, or (iii) designate new lenders who qualify as Eligible Assignees as additional Lenders hereunder (each, a “New Lender”), which New Lenders may assume the amount of the increase in the Revolving Commitment that has not been assumed by the consenting Lenders.

2.19.5 After completion of the foregoing, Administrative Agent shall give written notification to the Lenders and any New Lenders of the increase to the Revolving Commitment which shall thereupon become effective, and in connection with such notification Administrative Agent will distribute to the Borrower and the Lenders a revised Schedule 2.1 reflecting the then applicable Pro Rata Shares of the Lenders.

2.19.6 Each New Lender shall become an additional party hereto as a Lender concurrently with the effectiveness of the proposed increase in the Revolving Commitment upon its execution of an instrument of joinder to this Agreement, which is in form and substance reasonably acceptable to Administrative Agent and which, in any event, contains the representations, warranties, indemnities and other protections afforded to Administrative Agent and the other Lenders which would be granted or made by an Eligible Assignee by means of the execution of a Commitment Assignment and Acceptance.

2.19.7 Subject to the foregoing, any increase to the Revolving Commitment requested under this Section shall be effective upon the date agreed to by Administrative Agent and Borrower and shall be in the principal amount equal to (i) the amount which consenting Lenders are willing to assume as increases to their respective Revolving Commitment plus (ii) the amount assumed by New Lenders. Upon the effectiveness of any such increase, each Revolving Loan outstanding shall be refinanced with new Loans reflecting the adjusted Pro Rata Share of each Lender in the Revolving Commitment if there is any change thereto and Borrower shall:

(i) issue a replacement Revolving Note to each affected Lender and a new Revolving Note to each New Lender, and the Pro Rata Share of each Lender will be adjusted to give effect to the increase in the Revolving Commitment;

(ii) execute and deliver to Administrative Agent such amendments to the Loan Documents as Administrative Agent may reasonably request relating to such increase to, among other things, assure the continued priority and perfection the Lien granted by Borrower to Security Agent, for the ratable benefit of Lenders, upon all of Borrower’s right, title and interest in the Collateral; and

(iii) pay to the existing Lenders any breakage costs as set forth in Section 2.8.5, which are payable in connection with the refinancing of any LIBOR Loans.

2.19.8 Notwithstanding the foregoing or anything in this Agreement to the contrary, any increase in the Revolving Commitment pursuant to this Section 2.19 shall not increase the amount of the Letter of Credit sublimit as set forth in Section 2.3.1 or the maximum amount of the Swing Line Commitment unless consented to in writing by Issuing Lender or Swing Line Lender, respectively.

3. SECURITY

To secure the prompt payment and performance of all Obligations and all obligations of Borrower under Non-Lender Protection Agreements, for the ratable benefit of Credit Facility Lenders and Non-Lenders, Borrower, each Engine Owner, each Equipment Owner and each Leasing Subsidiary, as applicable, shall enter into the Collateral Documents creating security interests in the Collateral.

11. [Intentionally deleted.]

12. MISCELLANEOUS

12.1 Complete Agreement; Modification of Agreement. This Agreement and the other Loan Documents constitute the complete agreement among the parties with respect to the subject matter hereof and thereof, supersede all prior agreements, commitments, understandings or inducements (oral or written, expressed or implied), and may not be modified, altered or amended except by a written agreement signed by Administrative Agent, Security Agent, Credit Facility Lenders, Borrower and each other Person executing this Agreement or any other Loan Document, as applicable, and in accordance with Section 12.16 hereof.

12.2 Reimbursement and Expenses. Borrower will promptly pay:

12.2.1 without regard for whether any Loans are made or any Letter of Credit Obligations are incurred, all reasonable out-of-pocket expenses of Agents in connection with the preparation, negotiation, execution, and delivery of this Agreement, the Notes and the other Loan Documents, including all due diligence, all post-closing matters, syndication, and the transactions contemplated hereunder and thereunder and the making of the Loans and the incurrence of the Letter of Credit Obligations, including, recording and filing fees, and the reasonable attorneys’ fees and disbursements of counsel for Agents;

12.2.3 all of Agents’ out-of-pocket costs and expenses of obtaining performance under this Agreement or the other Loan Documents, of collection of the Obligations, in any arbitration, mediation, legal action or proceeding (including any case under the Bankruptcy Code or similar laws), which, in each case, shall include reasonable fees and expenses of counsel for Agents and each Credit Facility Lender;

12.2.4 all Charges levied on, or assessed, placed or made against any Collateral, the Notes or the other Loan Documents or the Obligations.

12.3 Indemnity.

12.3.1 Borrower shall indemnify and hold each Indemnified Person harmless from and against any Claim which may be instituted or asserted against or incurred by any such Indemnified Person as the result of credit having been extended or not extended under this Agreement and the other Loan

Documents or otherwise in connection with or arising out of the transactions contemplated hereunder or thereunder, including any Claim for Environmental Liabilities and Costs and legal costs and expenses of disputes between the parties to this Agreement; provided, that Borrower shall not be liable for indemnification of an Indemnified Person to the extent that (a) such Claim is brought by any Indemnified Person against Borrower and Borrower is the prevailing party thereunder or (b) any such Claim is finally determined by a court of competent jurisdiction to have resulted from such Indemnified Person’s gross negligence or willful misconduct. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO ANY OTHER PARTY TO ANY LOAN DOCUMENT, ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED OR NOT EXTENDED UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

12.3.2 In any suit, proceeding or action brought by Agent or any Credit Facility Lender relating to any item of Collateral or any amount owing hereunder, or to enforce any provision of any item of Collateral, Borrower shall save, indemnify and keep Agent and each Credit Facility Lender harmless from and against all expense, loss or damage suffered by reason of such action or any defense, setoff, or counterclaim asserted for any reason by the other party or parties to such litigation and however arising unless (a) such suit, proceeding or action is brought by Agent or any Credit Facility Lender against Borrower and Borrower is the prevailing party thereunder, or (b) any such suit, proceeding or action is finally determined by a court of competent jurisdiction to have resulted from Agent’s or any Credit Facility Lender’s gross negligence or willful misconduct. All obligations of Borrower with respect to any item of Collateral shall be and remain enforceable against, and only against, Borrower and shall not be enforceable against Agent or any Credit Facility Lender. This Section 12.3.2 shall survive the Termination Date.

12.4 No Waiver. Neither Agent’s nor any Credit Facility Lender’s failure, at any time or times, to require strict performance by Borrower of any provision of any Loan Document, nor Agent’s or any Credit Facility Lender’s failure to exercise, nor any delay in exercising, any right, power or privilege under this Agreement, (a) shall waive, affect or diminish any right of such Agent or any Credit Facility Lender thereafter to demand strict compliance and performance therewith, or (b) shall operate as a waiver thereof. Any suspension or waiver of a Default, Event of Default, or other provision under the Loan Documents must be in writing signed by an authorized employee of Administrative Agent or any Credit Facility Lender to be effective and shall not suspend, waive or affect any other Default or Event of Default, whether the same is prior or subsequent thereto and whether of the same or of a different type, and shall not be construed as a bar to any right or remedy which Agent or any Credit Facility Lender would otherwise have had on any future occasion.

12.5 Severability; Drafting. Wherever possible, each provision of the Loan Documents shall be interpreted in such manner as to be effective and valid under Applicable Law, but if any provision of any Loan Document shall be prohibited by or invalid under Applicable Law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of such Loan Document. Except as otherwise expressly provided herein or in any other Loan Document, all undertakings, agreements, covenants, warranties and representations of or binding upon Borrower and all rights of Agents and Credit Facility Lender, all as contained in the Loan Documents, shall not terminate or expire, but rather shall survive such termination or cancellation and shall continue in full force and effect until the Termination Date; provided, that the reimbursement and expense provisions of Section 12.2, the indemnity provisions of Section 12.3, and the governing law and venue provisions of Section 12.14 shall all survive the Termination Date. In the event of a dispute between any of the parties hereto over the meaning of this Agreement, all parties shall be deemed to have been the drafter hereof, and any Applicable Law that states that contracts are construed against the drafter shall not apply.

12.6 Conflict of Terms. Except as otherwise provided in any Loan Document by specific reference to the applicable provisions of this Agreement, if any provision contained in this Agreement is in conflict with, or inconsistent with, any provision in any other Loan Document, the provision contained in this Agreement shall govern and control.

12.8 Binding Effect; Assignment.

12.8.1 This Agreement and the other Loan Documents to which Borrower is a party will be binding upon and inure to the benefit of Borrower, Agents, each of Credit Facility Lenders, and their respective permitted successors and assigns, except that Borrower may not assign its rights hereunder or thereunder or any interest herein or therein without the prior written consent of all Lenders. Each Credit Facility Lender represents that it is not acquiring its Note with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (subject to any requirement that disposition of such Note must be within the control of such Lender). Any Credit Facility Lender may at any time pledge its Note or any other instrument evidencing its rights as a lender under this Agreement to a Federal Reserve Bank, but no such pledge shall release that lender from its obligations hereunder or grant to such Federal Reserve Bank the rights of a Credit Facility Lender hereunder absent foreclosure of such pledge.

12.8.2 From time to time following the Closing Date, each Lender may assign to one or more Eligible Assignees all or any portion of its Pro Rata Share of the Revolving Commitment; provided that (i) such Eligible Assignee, if not then a Lender or an Affiliate of the assigning Lender, shall be approved by Administrative Agent and, provided no Default or Event of Default then exists, Borrower, which approval(s) shall not be unreasonably withheld, conditioned or delayed; (ii) such assignment shall be evidenced by a Commitment Assignment and Acceptance, a copy of which shall be furnished to Administrative

Agent as hereinbelow provided; (iii) except in the case of an assignment (a) to an Affiliate of the assigning Lender or to another Lender or (b) of the entire remaining Revolving Commitment of the assigning Lender, the assignment shall not assign a Pro Rata Share of the Revolving Commitment that is equivalent to less than $5,000,000.00; (iv) the effective date of any such assignment shall be as specified in the Commitment Assignment and Acceptance, but not earlier than the date which is five (5) Business Days after the date Administrative Agent has received the Commitment Assignment and Acceptance; and (v) such Eligible Assignee shall execute an Alternative Dispute Resolution Agreement, in form and substance satisfactory to Administrative Agent. Upon the effective date of such Commitment Assignment and Acceptance, the Eligible Assignee named therein shall be a Lender for all purposes of this Agreement, with the Pro Rata Share of the Revolving Commitment therein set forth and, to the extent of such Pro Rata Share, the assigning Lender shall be released from its further obligations under this Agreement. Borrower agrees that it shall execute and deliver (against delivery by the assigning Lender to Borrower of its Note(s)) to such assignee Lender, Note(s) evidencing that assignee Lender’s Pro Rata Share of the Revolving Commitment, and to the assigning Lender, Note(s) evidencing the Pro Rata Share retained by the assigning Lender.

12.8.3 By executing and delivering a Commitment Assignment and Acceptance, the Eligible Assignee thereunder acknowledges and agrees that: (i) other than the representation and warranty that it is the legal and beneficial owner of the Pro Rata Share of the Revolving Commitment being assigned thereby free and clear of any adverse claim, the assigning Lender has made no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness or sufficiency of this Agreement or any other Loan Document; (ii) the assigning Lender has made no representation or warranty and assumes no responsibility with respect to the financial condition of Borrower or the performance by Borrower of the Obligations; (iii) it has received a copy of this Agreement, together with copies of the most recent financial statements delivered pursuant to Section 8 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Commitment Assignment and Acceptance; (iv) it will, independently and without reliance upon Administrative Agent or any Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) it appoints and authorizes Administrative Agent to take such action and to exercise such powers under this Agreement as are delegated to Administrative Agent by this Agreement; and (vi) it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

12.8.4 Administrative Agent shall maintain at Administrative Agent’s Office a copy of each Commitment Assignment and Acceptance

delivered to it and a register (the “Register”) of the names and address of each of the Lenders and the Pro Rata Share of the Commitments held by each Lender, giving effect to each Commitment Assignment and Acceptance. The Register shall be available during normal business hours for inspection by Borrower or any Lender upon reasonable prior notice to Administrative Agent. After receipt of a completed Commitment Assignment and Acceptance executed by any Lender and an Eligible Assignee, and receipt of a non-refundable assignment fee of Three Thousand Five Hundred Dollars ($3,500.00) from such Lender or Eligible Assignee, Administrative Agent shall, promptly following the effective date thereof, provide to Borrower and the Lenders a revised Schedule 2.1 giving effect thereto. Borrower, Administrative Agent and the Lenders shall deem and treat the Persons listed as Lenders in the Register as the holders and owners of the Pro Rata Share of the Revolving Commitment listed therein for all purposes hereof, and no assignment or transfer of any such Pro Rata Share of the Revolving Commitment shall be effective, in each case unless and until a Commitment Assignment and Acceptance effecting the assignment or transfer thereof shall have been accepted by Administrative Agent and recorded in the Register as provided above. Prior to such recordation, all amounts owed with respect to the applicable Pro Rata Share of the Revolving Commitment shall be owed to the Lender listed in the Register as the owner thereof, and any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is listed in the Register as a Lender shall be conclusive and binding on any subsequent holder, assignee or transferee of the corresponding Pro Rata Share of the Revolving Commitment.

12.8.5 Each Lender may from time to time grant participations to one or more banks or other financial institutions in a portion of its Pro Rata Share of the Revolving Commitment; provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged; (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations; (iii) the participating banks or other financial institutions shall not be a Lender hereunder for any purpose except, if the participation agreement so provides, for the purposes of Section 12.3 but only to the extent that the cost of such benefits to Borrower does not exceed the cost which Borrower would have incurred in respect of such Lender absent the participation; (iv) Borrower, Agents and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement; (v) the participation interest shall be expressed as a percentage of the granting Lender’s Pro Rata Share of the Revolving Commitment as it then exists and shall not restrict an increase in the Revolving Commitment, or in the granting Lender’s Pro Rata Share of the Revolving Commitment, so long as the amount of the participation interest is not affected thereby; and (vi) the consent of the holder of such participation interest shall not be required for amendments or waivers of provisions of the Loan Documents and the Lender granting such participation shall be empowered to bind such participant for the purpose of all consents, waiver and amendments other than those which (A) extend the Maturity Date or any other date upon which any payment of money is due to the Lenders, (B)

reduce the rate of interest on the Notes, any fee or any other monetary amount payable to the Lenders, (C) reduce the amount of any installment of principal due under the Notes, or (D) release all or a substantial portion of the Collateral from the Lien of the Collateral Documents if the effect thereof is to cause the outstanding principal amount of the Loans to exceed the amount of the Borrowing Base, except if such release of Collateral occurs in connection with a disposition permitted under this Agreement in which case such release shall not require the consent of any of the Lenders or of any holder of a participation interest in the Revolving Commitment.

12.9 Right of Setoff. If an Event of Default has occurred and is continuing, Agent or any Lender (but in each case only with the consent of the Requisite Lenders) may exercise its rights under Article 9 of the Uniform Commercial Code and other Applicable Laws and, to the extent permitted by Applicable Laws, apply any funds in any deposit account maintained with it by Borrower and/or any Property of Borrower in its possession against the Obligations.

12.10 Sharing of Setoffs. Each Lender severally agrees that if it, through the exercise of any right of setoff, banker’s lien or counterclaim against Borrower, or otherwise, receives payment of the Obligations held by it that is ratably more than any other Lender, through any means, receives in payment of the Obligations held by that Lender, then, subject to Applicable Laws: (a) the Lender exercising the right of setoff, banker’s lien or counterclaim or otherwise receiving such payment shall purchase, and shall be deemed to have simultaneously purchased, from each of the other Lenders a participation in the Obligations held by the other Lenders and shall pay to the other Lenders a purchase price in an amount so that the share of the Obligations held by each Lender after the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment shall be in the same proportion that existed prior to the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment; and (b) such other adjustments and purchases of participations shall be made from time to time as shall be equitable to ensure that all of the Lenders share any payment obtained in respect of the Obligations ratably in accordance with each Lender’s share of the Obligations immediately prior to, and without taking into account, the payment; provided that, if all or any portion of a disproportionate payment obtained as a result of the exercise of the right of setoff, banker’s lien, counterclaim or otherwise is thereafter recovered from the purchasing Lender by Borrower or any Person claiming through or succeeding to the rights of Borrower, the purchase of a participation shall be rescinded and the purchase price thereof shall be restored to the extent of the recovery, but without interest. Each Lender that purchases a participation in the Obligations pursuant to this Section 12.10 shall from and after the purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased. Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in an Obligation so purchased pursuant to this Section 12.10 may exercise any and all rights of setoff, banker’s lien or counterclaim with respect to the participation as fully as if the Lender were the original owner of the Obligation purchased.

12.11 Section Titles. The Section titles and Table of Contents contained in this Agreement and any other Loan Document are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

12.16.4 To release all or a substantial portion of the Collateral from the Lien of the Collateral Documents if the effect thereof would be to cause a Borrowing Base Deficiency;

12.16.5 To amend or waive Section 4 or this Section 12.16 or any part thereof; or

12.16.6 To amend any provision of this Agreement that expressly requires the consent or approval of all or a specified portion of the Lenders.

12.17 Foreign Lenders and Participants. Each Lender that is incorporated or otherwise organized under the Applicable Laws of a jurisdiction other than the United States of America or any State thereof or the District of Columbia shall deliver to Borrower (with a copy to Administrative Agent), on or before the Closing Date (or on or before accepting an assignment or receiving a participation interest herein pursuant to Section 12.8, if applicable) two duly completed copies, signed by an authorized officer, of either Form 1001 (relating to such Lender and entitling it to a complete exemption from withholding on all payments to be made to such Lender by Borrower pursuant to this Agreement) or Form W-8BEN (relating to all payments to be made to such Lender by the Borrower pursuant to this Agreement) of the United States Internal Revenue Service or such other evidence (including, if reasonably necessary, Form W-9) satisfactory to Borrower and Administrative Agent that no withholding under the federal income tax laws is required with respect to such Lender. Thereafter and from time to time, each such Lender shall (a) promptly submit to Borrower (with a copy to Administrative Agent), such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to Borrower and Administrative Agent of any available exemption from, United States withholding taxes in respect of all payments to be made to such Lender by Borrower pursuant to this Agreement and (b) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re designation of its LIBOR lending office, if any) to avoid any requirement of Applicable Laws that Borrower make any deduction or withholding for taxes from amounts payable to such Lender. In the event that Borrower or Administrative Agent become aware that a participation has been granted pursuant to Section 12.8.5 to a financial institution that is incorporated or otherwise organized under the laws of a jurisdiction other than the United States of America, any State thereof or the District of Columbia, then, upon request made by Borrower or Administrative Agent to the Lender which granted such participation, such Lender shall cause such participant financial institution to deliver the same documents and information to Borrower and Administrative Agent as would be required under this Section if such financial institution were a Lender.

of each Lease, for the benefit of the Security Agent; and (iii) that the Security Agent shall not be liable in the event of any damage, loss or destruction of any of the documents or instruments to be delivered therein, including without limitation, the “chattel paper” originals of each Lease, by such third party custodian.

13. ADMINISTRATIVE AGENT

13.1 Appointment and Authorization. Subject to Section 12.8, each Credit Facility Lender hereby irrevocably appoints and authorizes Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to Administrative Agent by the terms thereof or are reasonably incidental, as determined by Administrative Agent, thereto. This appointment and authorization is intended solely for the purpose of facilitating the servicing of the Loans and does not constitute appointment of Administrative Agent as trustee for any Credit Facility Lender or as representative of any Credit Facility Lender for any other purpose and, except as specifically set forth in the Loan Documents to the contrary, Administrative Agent shall take such action and exercise such powers only in an administrative and ministerial capacity.

13.2 Administrative Agent and Affiliates. Union Bank, N.A. (and each successor Administrative Agent) has the same rights and powers under the Loan Documents as any other Credit Facility Lender and may exercise the same as though it were not Administrative Agent, and the term “Lender” or “Lenders” includes Union Bank, N.A. in its individual capacity. Union Bank, N.A. (and each successor Administrative Agent) and its Affiliates may accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with Borrower or any Affiliate of Borrower, as if it were not Administrative Agent and without any duty to account therefor to Credit Facility Lenders. Union Bank, N.A. (and each successor Administrative Agent) need not account to any other Credit Facility Lender for any monies received by it in its capacity as a Credit Facility Lender hereunder. Administrative Agent shall not be deemed to hold a fiduciary relationship with any Credit Facility Lender and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise exist against Administrative Agent.

13.3 Lenders’ Credit Decisions. Each Credit Facility Lender agrees that it has, independently and without reliance upon Administrative Agent, any other Credit Facility Lender or the directors, officers, agents, employees or attorneys of the foregoing parties, and instead in reliance upon information supplied to it by or on behalf of Borrower and upon such other information as it has deemed appropriate, made its own independent credit analysis and decision to enter into this Agreement. Each Credit Facility Lender also agrees that it shall, independently and without reliance upon Administrative Agent, any other Credit Facility Lender or the directors, officers, agents, employees or attorneys of the foregoing parties, continue to make its own independent credit analyses and decisions in acting or not acting under the Loan Documents.

13.4 Action by Administrative Agent.

13.4.1 Absent actual knowledge of Administrative Agent of the existence of a Default, Administrative Agent may assume that no Default has

occurred and is continuing, unless Administrative Agent (or the Credit Facility Lender that is then Administrative Agent) has received notice from Borrower stating the nature of the Default or has received notice from a Credit Facility Lender stating the nature of the Default and that such Credit Facility Lender considers the Default to have occurred and to be continuing.

13.4.2 Administrative Agent has only those obligations under the Loan Documents as are expressly set forth therein.

13.4.3 Except for any obligation expressly set forth in the Loan Documents and as long as Administrative Agent may assume that no Event of Default has occurred and is continuing, Administrative Agent may, but shall not be required to, exercise its discretion to act or not act, except that Administrative Agent shall be required to act or not act upon the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 12.16) and those instructions shall be binding upon Administrative Agent and Credit Facility Lenders, provided that Administrative Agent shall not be required to act or not act if to do so would be contrary to any Loan Document or to Applicable Law or would result, in the reasonable judgment of Administrative Agent, in substantial risk of liability to Administrative Agent.

13.4.4 If Administrative Agent has received a notice of any Event of Default, Administrative Agent shall immediately give notice thereof to Credit Facility Lenders and shall act or not act upon the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 12.16), provided that Administrative Agent shall not be required to act or not act if to do so would be contrary to any Loan Document or to Applicable Law or would result, in the reasonable judgment of Administrative Agent, in substantial risk of liability to Administrative Agent, and except that if the Requisite Lenders fail, for five (5) Business Days after the receipt of notice from Administrative Agent, to instruct Administrative Agent, then Administrative Agent, in its sole discretion, may act or not act as it deems advisable for the protection of the interests of Credit Facility Lenders.

13.4.5 Absent its gross negligence or willful misconduct, Administrative Agent shall have no liability to any Credit Facility Lender for acting, or not acting, as instructed by the Requisite Lenders, notwithstanding any other provision hereof.

13.5 Liability of Administrative Agent. Neither Administrative Agent nor any of its directors, officers, agents, employees or attorneys shall be liable for any action taken or not taken by them under or in connection with the Loan Documents, except for their own gross negligence or willful misconduct. Without limitation on the foregoing, Administrative Agent and its directors, officers, agents, employees and attorneys:

13.5.1 May treat the payee of any Note as the holder thereof until Administrative Agent receives notice of the assignment or transfer thereof,

in form satisfactory to Administrative Agent, signed by the payee, and may treat each Credit Facility Lender as the owner of that Credit Facility Lender’s interest in the Obligations for all purposes of this Agreement until Administrative Agent receives notice of the assignment or transfer thereof, in form satisfactory to Administrative Agent, signed by that Credit Facility Lender;

13.5.2 May consult with legal counsel (including in-house legal counsel), accountants (including in house accountants) and other professionals or experts selected by it, or with legal counsel, accountants or other professionals or experts for Borrower or Credit Facility Lenders, and shall not be liable for any action taken or not taken by it in good faith in accordance with any advice of such legal counsel, accountants or other professionals or experts selected by it with reasonable care;

13.5.3 Shall not be responsible to any Credit Facility Lender for any statement, warranty or representation made in any of the Loan Documents or in any notice, certificate, report, request or other statement (written or oral) given or made in connection with any of the Loan Documents except for those expressly made by it;

13.5.4 Except to the extent expressly set forth in the Loan Documents, shall have no duty to ask or inquire as to the performance or observance by Borrower of any of the terms, conditions or covenants of any of the Loan Documents or to inspect any collateral or any Property, books or records of Borrower;

13.5.5 Will not be responsible to any Credit Facility Lender for the due execution, legality, validity, enforceability, genuineness, effectiveness, sufficiency or value of any Loan Document, any other instrument or writing furnished pursuant thereto or in connection therewith, or any collateral;

13.5.6 Will not incur any liability by acting or not acting in reliance upon any Loan Document, notice, consent, certificate, statement, request or other instrument or writing reasonably believed by it to be genuine and signed or sent by the proper party or parties; and

13.5.7 Will not incur any liability for any arithmetical error in computing any amount paid or payable by Borrower thereof or paid or payable to or received or receivable from any Credit Facility Lender under any Loan Document, including, without limitation, principal, interest, commitment fees, Loans and other amounts; provided that, promptly upon discovery of such an error in computation, Administrative Agent, Credit Facility Lenders and (to the extent applicable) Borrower shall make such adjustments as are necessary to correct such error and to restore the parties to the position that they would have occupied had the error not occurred.

13.6 Indemnification. Each Credit Facility Lender shall, ratably in accordance with its proportion of the aggregate Indebtedness then evidenced by the Notes, indemnify and hold Administrative Agent and its directors, officers, agents, employees and attorneys harmless against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys’ fees and disbursements and allocated costs of attorneys employed by Administrative Agent) that may be imposed on, incurred by or asserted against it or them in any way relating to or arising out of the Loan Documents (other than losses incurred by reason of the failure of Borrower to pay the Indebtedness represented by the Notes) or any action taken or not taken by it as Administrative Agent thereunder, except such as result from its own gross negligence or willful misconduct. Without limitation on the foregoing, each Credit Facility Lender shall reimburse Administrative Agent upon demand for that Credit Facility Lender’s share (as set forth in this Section) of any out of pocket cost or expense incurred by Administrative Agent in connection with the negotiation, preparation, execution, delivery, amendment, waiver, restructuring, reorganization (including a bankruptcy reorganization), enforcement or attempted enforcement of the Loan Documents, to the extent that Borrower or any other party is required by Section 12.2 to pay that cost or expense but fails to do so upon demand. Nothing in this Section 13.6 shall entitle Administrative Agent or any indemnitee referred to above to recover any amount from Credit Facility Lenders if and to the extent that such amount has theretofore been recovered from Borrower. To the extent that Administrative Agent or any indemnitee referred to above is later reimbursed such amount by Borrower, it shall return the amounts paid to it by Credit Facility Lenders in respect of such amount.

13.7 Successor Administrative Agent. Administrative Agent may, and at the request of the Requisite Lenders shall, resign as Administrative Agent upon reasonable notice to Credit Facility Lenders and Borrower, effective upon acceptance of appointment by a successor Administrative Agent. If Administrative Agent shall resign as Administrative Agent under this Agreement, the Requisite Lenders shall appoint from among Credit Facility Lenders a successor Administrative Agent for Credit Facility Lenders, which successor Administrative Agent shall be approved by Borrower (and such approval shall not be unreasonably withheld or delayed). If no successor Administrative Agent is appointed prior to the effective date of the resignation of Administrative Agent, Administrative Agent may appoint, after consulting with Credit Facility Lenders and Borrower, a successor Administrative Agent from among Credit Facility Lenders. Upon the acceptance of its appointment as successor Administrative Agent hereunder, such successor Administrative Agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor Administrative Agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 13, and Section 12.3, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Notwithstanding the foregoing, if (a) Administrative Agent has not been paid those fees referenced in Section 2.6.3 or has not been reimbursed for any expense reimbursable to it under Sections 12.2 or 12.3, in either case for a period of at least one (1) year and (b) no successor Administrative Agent has accepted appointment as Administrative Agent by the date which is thirty (30) days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and Credit Facility Lenders shall perform all of the

duties of Administrative Agent hereunder until such time, if any, as the Requisite Lenders appoint a successor Administrative Agent as provided for above.

13.8 No Obligations of Borrower. Nothing contained in this Section 13 shall be deemed to impose upon Borrower any obligation in respect of the due and punctual performance by Administrative Agent of its obligations to Credit Facility Lenders under any provision of this Agreement, and Borrower shall have no liability to Administrative Agent or any of Credit Facility Lenders in respect of any failure by Administrative Agent or any Credit Facility Lender to perform any of its obligations to Administrative Agent or Credit Facility Lenders under this Agreement. Without limiting the generality of the foregoing, where any provision of this Agreement relating to the payment of any amounts due and owing under the Loan Documents provides that such payments shall be made by Borrower to Administrative Agent for the account of Credit Facility Lenders, Borrower’s obligations to Credit Facility Lenders in respect of such payments shall be deemed to be satisfied upon the making of such payments to Administrative Agent in the manner provided by this Agreement. In addition, Borrower may rely on a written statement by Administrative Agent to the effect that it has obtained the written consent of the Requisite Lenders or Credit Facility Lenders, as applicable under Section 12.16, in connection with a waiver, amendment, consent, approval or other action by Credit Facility Lenders hereunder, and shall have no obligation to verify or confirm the same.

14. SECURITY AGENT

14.1 Appointment and Authorization. Each Credit Facility Lender hereby irrevocably appoints and authorizes Security Agent to take such action as agent on its behalf and to exercise such powers under the Collateral Documents and any other Loan Documents as are delegated to Security Agent by the terms thereof or are reasonably incidental, as determined by Security Agent, thereto. This appointment and authorization is intended solely for the purpose of securing the Collateral as set forth in this Agreement and does not constitute appointment of Security Agent as trustee for any Credit Facility Lender or as representative of any Credit Facility Lender for any other purpose and, except as specifically set forth in the Loan Documents to the contrary, Security Agent shall take such action and exercise such powers only in an administrative and ministerial capacity.

14.2 Security Agent and Affiliates. Union Bank, N.A. (and each successor Security Agent) shall not be deemed to hold a fiduciary relationship with any Credit Facility Lender and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise exist against Security Agent.

14.3 Proportionate Interest in any Collateral. Security Agent, on behalf of Credit Facility Lenders and Non-Lenders, shall hold in accordance with the Loan Documents all items of any collateral or interests therein to be received or held by Security Agent. Subject to Agents’ and Credit Facility Lenders’ rights to reimbursement for their costs and expenses hereunder (including reasonable attorneys’ fees and disbursements and other professional services and the reasonably allocated costs of attorneys employed by Security Agent or a Credit Facility Lender) and subject to the application of payments in accordance with Section 9.4, each Credit Facility Lender and Non-Lender shall have an interest in such collateral or interests therein in the same proportion that the aggregate obligations owed such Credit Facility Lender or Non-Lender, under

the Loan Documents and/or any Non-Lender Protection Agreement, as applicable, bears to the aggregate obligations owed under the Loan Documents and all Non-Lender Protection Agreement, without priority or preference among Credit Facility Lenders.

14.4 Lenders’ Credit Decisions. Each Credit Facility Lender agrees that it has, independently and without reliance upon Security Agent, any other Credit Facility Lender or the directors, officers, agents, employees or attorneys of the foregoing parties, and instead in reliance upon information supplied to it by or on behalf of Borrower and upon such other information as it has deemed appropriate, made its own independent credit analysis and decision to enter into this Agreement. Each Credit Facility Lender also agrees that it shall, independently and without reliance upon Security Agent, any other Credit Facility Lender or the directors, officers, agents, employees or attorneys of the foregoing parties, continue to make its own independent credit analyses and decisions in acting or not acting under the Loan Documents.

14.5 Action by Security Agent.

14.5.1 Absent actual knowledge of Security Agent of the existence of a Default, Security Agent may assume that no Default has occurred and is continuing, unless Security Agent (or the Lender that is then Security Agent) has received notice from Borrower stating the nature of the Default or has received notice from a Credit Facility Lender stating the nature of the Default and that such Credit Facility Lender considers the Default to have occurred and to be continuing.

14.5.2 Security Agent has only those obligations under the Loan Documents as are expressly set forth therein.

14.5.3 Except for any obligation expressly set forth in the Loan Documents and as long as Security Agent may assume that no Event of Default has occurred and is continuing, Security Agent may, but shall not be required to, exercise its discretion to act or not act, except that Security Agent shall be required to act or not act upon the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 12.16) and those instructions shall be binding upon Security Agent and all Credit Facility Lenders, provided that Security Agent shall not be required to act or not act if to do so would be contrary to any Loan Document or to Applicable Law or would result, in the reasonable judgment of Security Agent, in substantial risk of liability to Security Agent.

14.5.4 If Security Agent has received a notice specified in Section 14.5.1, Security Agent shall immediately give notice thereof to Credit Facility Lenders and shall act or not act upon the instructions of the Requisite Lenders (or of all the Lenders, to the extent required by Section 12.16), provided that Security Agent shall not be required to act or not act if to do so would be contrary to any Loan Document or to Applicable Law or would result, in the reasonable judgment of Security Agent, in substantial risk of liability to Security Agent, and except that if the Requisite Lenders fail, for five (5) Business Days after the receipt of notice from Security Agent, to instruct Security Agent, then

Security Agent, in its sole discretion, may act or not act as it deems advisable for the protection of the interests of Credit Facility Lenders.

14.5.5 Absent its gross negligence or willful misconduct, Security Agent shall have no liability to any Credit Facility Lender for acting, or not acting, as instructed by the Requisite Lenders, notwithstanding any other provision hereof.

14.6 Liability of Security Agent. Neither Security Agent nor any of its directors, officers, agents, employees or attorneys shall be liable for any action taken or not taken by them under or in connection with the Loan Documents, except for their own gross negligence or willful misconduct. Without limitation on the foregoing, Security Agent and its directors, officers, agents, employees and attorneys:

14.6.1 May treat the payee of any Note as the holder thereof until Security Agent receives notice of the assignment or transfer thereof, signed by the payee, and may treat each Credit Facility Lender as the owner of that Credit Facility Lender’s interest in the Obligations for all purposes of this Agreement until Security Agent receives notice of the assignment or transfer thereof, signed by that Credit Facility Lender;

14.6.2 May consult with legal counsel (including in-house legal counsel), accountants (including in house accountants) and other professionals or experts selected by it, or with legal counsel, accountants or other professionals or experts for Borrower or Credit Facility Lenders, and shall not be liable for any action taken or not taken by it in good faith in accordance with any advice of such legal counsel, accountants or other professionals or experts selected by it with reasonable care;

14.6.3 Shall not be responsible to any Credit Facility Lender for any statement, warranty or representation made in any of the Loan Documents or in any notice, certificate, report, request or other statement (written or oral) given or made in connection with any of the Loan Documents except for those expressly made by it;

14.6.4 Except to the extent expressly set forth in the Loan Documents, shall have no duty to ask or inquire as to the performance or observance by Borrower of any of the terms, conditions or covenants of any of the Loan Documents or to inspect any collateral or any Property, books or records of Borrower;

Without limitation on the foregoing, each Credit Facility Lender shall reimburse Security Agent upon demand for that Lender’s Pro Rata Share of any out of pocket cost or expense incurred by Security Agent in connection with the negotiation, preparation, execution, delivery, amendment, waiver, restructuring, reorganization (including a bankruptcy reorganization), enforcement or attempted enforcement of the Loan Documents, to the extent that Borrower or any other party is required by Section 12.2 to pay that cost or expense but fails to do so upon demand. Nothing in this Section 14.7 shall entitle Security Agent or any indemnitee referred to above to recover any amount from Credit Facility Lenders if and to the extent that such amount has theretofore been recovered from Borrower. To the extent that Security Agent or any indemnitee referred to above is later reimbursed such amount by Borrower, it shall return the amounts paid to it by Credit Facility Lenders in respect of such amount.

14.8 Successor Security Agent.

15.1.1 In the event that any Governmental Authority imposes on any Credit Facility Lender any reserve or comparable requirement (including any emergency, supplemental or other reserve) with respect to the Eurodollar liabilities (as defined in Regulation D or any comparable regulation of any Governmental Authority having jurisdiction over any Credit Facility Lender) of any Credit Facility Lender, Borrower shall pay such lender within five (5) Business Days after demand all amounts necessary to compensate such Credit Facility Lender (determined as though such lender’s LIBOR lending office had funded 100% of its LIBOR Loan in the Designated Eurodollar Market) in respect of the imposition of such reserve requirements (provided, that Borrower shall not be obligated to pay any such amount which arose prior to the date which is forty five (45) days preceding the date of such demand or is attributable to periods prior to the date which is forty five (45) days preceding the date of such demand). Such Credit Facility Lender’s determination of such amount shall be conclusive in the absence of manifest error.

(ii) shall impose, modify or deem applicable any reserve not applicable or deemed applicable on the date hereof (including any reserve imposed by the Board of Governors of the Federal Reserve System, special deposit, capital or similar requirements against

assets of, deposits with or for the account of, or credit extended by, any Credit Facility Lender or its LIBOR lending office); or

(iii) shall impose on any Credit Facility Lender or its LIBOR lending office or the Designated Eurodollar Market any other condition affecting any LIBOR Loan, its Note evidencing such LIBOR Loan(s), its obligation to make LIBOR Loans or this Agreement, or shall otherwise affect any of the same;

and the result of any of the foregoing, as determined in good faith by any Credit Facility Lender, increases the cost to any Credit Facility Lender or its LIBOR lending office of making or maintaining any LIBOR Loan or in respect of any LIBOR Loan, any Note evidencing LIBOR Loans or its obligation to make LIBOR Loans or reduces the amount of any sum received or receivable by any Credit Facility Lender or its LIBOR lending office with respect to any LIBOR Loan, its Note evidencing such LIBOR Loan(s) or its obligation to make LIBOR Loans (assuming such Credit Facility Lender’s LIBOR lending office had funded 100% of its LIBOR Loan in the Designated Eurodollar Market), then, within five (5) Business Days after demand by such lender (with a copy to Administrative Agent), Borrower shall pay to such Credit Facility Lender such additional amount or amounts as will compensate such lender for such increased cost or reduction (determined as though such Credit Facility Lender’s LIBOR lending office had funded 100% of its LIBOR Loan in the Designated Eurodollar Market); provided, that Borrower shall not be obligated to pay any such amount which arose prior to the date which is ninety (90) days preceding the date of such demand or is attributable to periods prior to the date which is ninety (90) days preceding the date of such demand. A statement of Credit Facility Lender claiming compensation under this subsection shall be conclusive in the absence of manifest error.

15.1.3 If, after the date hereof, the existence or occurrence of any Special Eurodollar Circumstance shall, in the good faith opinion of Credit Facility Lender, make it unlawful or impossible for Credit Facility Lender or its LIBOR lending office to make, maintain or fund its portion of any LIBOR Loan, or materially restrict the authority of Credit Facility Lender to purchase or sell, or to take deposits of, Dollars in the Designated Eurodollar Market, or to determine or charge interest rates based upon the LIBOR Basis, and Credit Facility Lender shall so notify Administrative Agent, then such Credit Facility Lender’s obligation to make LIBOR Loans shall be suspended for the duration of such illegality or impossibility and Credit Facility Lender forthwith shall give notice thereof to the other Credit Facility Lenders and Borrower. Upon receipt of such notice, the outstanding principal amount of such Credit Facility Lender’s LIBOR Loans, together with accrued interest thereon, automatically shall be converted to Base Rate Loans on either (1) the last day of the LIBOR Loan Period(s) applicable to such LIBOR Loans if such lender may lawfully continue to maintain and fund such LIBOR Loans to such day(s) or (2) immediately if such lender may not lawfully continue to fund and maintain such LIBOR Loans to such day(s), provided that in such event the conversion shall not be subject to payment of a prepayment fee under Section 2.8.5. Credit Facility Lenders agrees to endeavor promptly to notify Borrower of any event of which it has actual knowledge, occurring after the Closing Date, which will cause any Credit Facility Lender to notify Administrative Agent under this Section, and agrees to designate a different

LIBOR lending office if such designation will avoid the need for such notice and will not, in the good faith judgment of such lender, otherwise be materially disadvantageous to such lender. In the event that any Credit Facility Lender is unable, for the reasons set forth above, to make, maintain or fund its portion of any LIBOR Loan, such Credit Facility Lender shall fund such amount as a Base Rate Loan for the same period of time, and such amount shall be treated in all respects as a Base Rate Loan. Any Credit Facility Lender whose obligation to make LIBOR Loans has been suspended under this Section shall promptly notify Administrative Agent and Borrower of the cessation of the Special Eurodollar Circumstance which gave rise to such suspension. Borrower shall have the right to terminate the Revolving Commitment of any Credit Facility Lender for which the funding of LIBOR Loans becomes unlawful or impossible, as set forth above, and to substitute a new Credit Facility Lender into this Agreement subject to the provisions of Section 12.8 of this Agreement.

15.1.4 If, with respect to any proposed LIBOR Loan, any Credit Facility Lender:

(i) reasonably determines that, by reason of circumstances affecting the Designated Eurodollar Market generally that are beyond the reasonable control of such lender, deposits in Dollars (in the applicable amounts) are not being offered to lender in the Designated Eurodollar Market for the applicable LIBOR Loan Period; or

(ii) LIBOR Basis as determined by such lender (i) does not represent the effective pricing to lender for deposits in Dollars in the Designated Eurodollar Market in the relevant amount for the applicable LIBOR Loan Period, or (ii) will not adequately and fairly reflect the cost to such lender of making the applicable LIBOR Loans;

then such Credit Facility Lender forthwith shall give notice thereof to Borrower and Administrative Agent, whereupon until such Credit Facility Lender notifies Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Credit Facility Lender to make any future LIBOR Loans shall be suspended and such Credit Facility Lender’s Loans shall be treated in all respects as a Base Rate Loan.

15.1.5 Each Credit Facility Lender agrees to endeavor promptly to notify Borrower of any event of which it has actual knowledge, occurring after the Closing Date, which will entitle any Credit Facility Lender to compensation pursuant to this Section, and agrees to designate a different LIBOR lending office if such designation will avoid the need for or reduce the amount of such compensation and will not, in the good faith judgment of such lender, otherwise be materially disadvantageous to lender. Any request for compensation by any Credit Facility Lender under this Section shall set forth the basis upon which it has been determined that such an amount is due from Borrower, a calculation of the amount due, and a certification that the corresponding costs have been incurred by such lender.

15.2 Capital Adequacy. If, after the date hereof, any Credit Facility Lender (or any Affiliate of any Credit Facility Lender) shall have reasonably determined that the adoption of any Applicable Law, governmental rule, regulation or order regarding the capital adequacy of banks or bank holding companies, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Credit Facility Lender (or any Affiliate of any Credit Facility Lender) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the capital of Credit Facility Lender (or any Affiliate of Credit Facility Lender) as a consequence of any of such Credit Facility Lender’s obligations hereunder to a level below that which it could have achieved but for such adoption, change or compliance (taking into consideration the policies of any Credit Facility Lender (or Affiliate of any Credit Facility Lender) with respect to capital adequacy immediately before such adoption, change or compliance and assuming that the capital of such Credit Facility Lender (or Affiliate of such Credit Facility Lender) was fully utilized prior to such adoption, change or compliance), then, upon demand by such Credit Facility Lender, Borrower shall immediately pay to such lender such additional amounts as shall be sufficient to compensate such lender for any such reduction actually suffered; provided, that there shall be no duplication of amounts paid to any Credit Facility Lender pursuant to this sentence and Section 15.1. Such Credit Facility Lender’s determination of the amount to be paid to such lender by Borrower as a result of any event referred to in this Section 15.2 shall, absent manifest error, be deemed final, binding and conclusive upon Borrower.

15.3 Federal Reserve System/Wire Transfers. The obligation of any Credit Facility Lender to make any loan by wire transfer to Borrower or any other Person shall be subject to all Applicable Laws, including the policy of the Board of Governors of the Federal Reserve System on Reduction of Payments System Risk as in effect from time to time. Borrower acknowledges that such laws, regulations and policy may delay the transmission of any funds to Borrower.

15.4 Assignment of Commitments Under Certain Circumstances; Duty to Mitigate. In the event any Credit Facility Lender (i) requests compensation pursuant to Section 15.1 or 15.2, above, (ii) delivers a notice described in Section 15.1 or 15.2, above, (iii) refuses to consent to any amendment, waiver or other modification of any Loan Document requested by any Borrower and which amendment, waiver or other modification is required under this Agreement for such amendment, waiver or other modification, or (iv) is a Defaulting Lender, Borrower may, at its sole expense and effort (including with respect to the assignment fee referred to in Section 12.8), upon notice to such Credit Facility Lender and Administrative Agent, require such Credit Facility Lender to transfer and assign, without recourse (in accordance with and subject to the restrictions contained in Section 12.8), all of its interests, rights and obligations under this Agreement to an Eligible Assignee that shall assume such assigned obligations (which Eligible Assignee may be another Lender, if a Lender accepts such assignment); provided that (x) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority having jurisdiction, (y) Borrower shall have received the prior written consent of Administrative Agent, which consent shall not unreasonably be withheld or delayed, and (z) the Borrower or such assignee shall have paid to the affected Credit Facility Lender in immediately available funds an amount equal to the sum of the principal of and interest accrued to the date of such payment on the outstanding Loans or Letter of Credit Obligations of such

IN WITNESS WHEREOF, this Agreement has been duly executed as of the date first written above.

Security Agent shall be permitted to observe and consult with Debtor and Debtor’s certified public accountants in the performance of these tasks.

9. License to Use Intellectual Property. For the purpose of enabling Security Agent to exercise its rights and remedies under the Loan Documents, Debtor hereby grants to Security Agent an irrevocable, non-exclusive license (exercisable only upon the occurrence and continuance of an Event of Default and without payment of royalty or other compensation to Debtor) to use, transfer, license or sublicense any Intellectual Property now owned, licensed to,

The Security Agent may, but subject to the provisions of Section 14 of the Credit Agreement, assign or otherwise transfer its rights hereunder or under the Credit Agreement to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to the Security Agent herein or otherwise, subject, however, to the provisions hereof; provided that, as soon as practicable after such assignment or transfer, Security Agent shall notify Debtor of any change in payment instructions necessitated by such assignment or transfer.

11. Partial Releases. Provided no Default or Event of Default exists and no Overadvance would result, Security Agent shall from time to time execute partial releases of Collateral (x) sold by Debtor in the ordinary course of its business in accordance with this Agreement or (y) financed or refinanced by the Debtor outside of the Credit Agreement (in accordance with the terms and provisions of the Credit Agreement) from the security interests under the Loan Documents which partial releases shall be in form reasonably satisfactory to Security Agents.

In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Secured Obligations and Security Agent’s Liens in the Collateral shall be reinstated and deemed reduced only by any amount paid and not so rescinded, reduced, restored or returned.

Time is of the essence for performance of any obligations under this Agreement.

In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Secured Obligations and Mortgagee’s Liens in the Collateral shall be reinstated and deemed reduced only by any amount paid and not so rescinded, reduced, restored or returned.

All such policies of insurance shall be written for the benefit of the Borrower as the insured, and Mortgagee and the Administrative Agent shall be named as additional insureds on liability insurance and Mortgagee shall be named as a loss payee on hull insurance, as applicable. Notwithstanding the foregoing or anything to the contrary herein, to the extent any Engine or item of Equipment included in the Collateral hereunder is included in the Borrowing Base, Borrower shall comply with all insurance requirements set forth in the Credit Agreement.

G-9

(b) Borrower expressly agrees that, subject to Sections 5.01 and 5.02 hereof, Mortgagee may collect, receive, assemble, process, appropriate and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, assign, give an option or options to purchase or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at public or private sale or sales, at any exchange at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. Mortgagee shall have the right upon any such public sale or sales and, to the extent permitted by law, to purchase for the benefit of Mortgagee by credit bid the whole or any part of said Collateral so sold, free of any right or equity of redemption, which equity of redemption Borrower hereby releases.

Borrower shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay the Secured Obligations and all other amounts to which Mortgagee is entitled.

(c) Borrower further agrees, subject to Sections 5.01 and 5.02 hereof, to assemble the Collateral and make it available to Mortgagee at places which Mortgagee shall reasonably select. Until Mortgagee is able to effect a sale, lease, or other disposition of the Collateral and subject to Sections 5.01 and 5.02 hereof, Mortgagee shall have the right to complete, assemble, use or operate the Collateral or any part thereof, to the extent that Mortgagee deems appropriate, for the purpose of preserving such Collateral or its value or for any other purpose. In addition, the Borrower will provide, without cost or expense to the Mortgagee, storage facilities for any such Engine or item of Equipment and will cause such Engine or item of Equipment to be maintained as required by the terms hereof and of the Credit Agreement.

(d) Upon the completion of any sale of any Collateral, full title and (subject to Sections 5.01 and 5.02 hereof) right of possession to the Engine or item of Equipment so sold shall (subject to any retention of title by the Mortgagee as part of the terms of such sale) pass to the accepted purchaser forthwith upon the completion of such sale, and the Borrower shall deliver, in accordance with the instructions of the Mortgagee (including causing the Engine or item of Equipment to be delivered to such airports as the Mortgagee may specify), such Engine or item of Equipment so sold. The Mortgagee is hereby irrevocably appointed the true and lawful attorney of the Borrower, and in its stead, to make all necessary conveyances of an Engine or item of Equipment if so sold. Nevertheless, if so requested by the Mortgagee or by any purchaser, the Borrower shall confirm any such sale or conveyance by executing and delivering all proper instruments of conveyance or releases as may be designated in any such request. If the Borrower shall for any reason fail to deliver such Engine or item of Equipment or any part thereof after demand by the Mortgagee, the Mortgagee (subject to Sections 5.01 and 5.02 hereof) may, without being responsible for loss or damage, except to the extent caused by the gross negligence or willful misconduct of the Mortgagee, (i) obtain a judgment conferring on the Mortgagee the right to immediate possession or requiring the Borrower to deliver immediate possession of all or part of such Engine or item of Equipment to the Mortgagee, to the entry of which judgment the Borrower hereby specifically consents, or (ii) with or, to the fullest extent provided by law, without such judgment, pursue the whole or any part of such Engine or item of Equipment wherever it may be found and enter any of the premises where such Engine or item of

G-10

Equipment may be and take possession of and remove the same. Upon every such taking of possession, the Mortgagee may (but shall not be obligated to), from time to time, make all such reasonable expenditures for maintenance, insurance, repairs, replacements, alterations, additions and improvements to and of the Engine or item of Equipment as it may deem proper.

(e) The Borrower hereby covenants and agrees that a notice, which shall be sent in accordance with the provisions of the Credit Agreement or this Mortgage, at least ten (10) Business Days before the date of any of the acts described in this Section 4.02 shall be deemed to be reasonable notice of such act and, specifically, reasonable notification of the time and place of any public sale hereunder and reasonable notification of the time after which any private sale or other intended disposition to be made hereunder is to be made.

(f) Mortgagee shall be entitled, as a matter of right as against the Borrower, without notice or demand and without regard to the adequacy of the security for the Secured Obligations by virtue of this Mortgage or any other collateral or to the solvency of the Borrower, upon the commencement of judicial proceedings by it to enforce any right under this Mortgage, to the appointment of a receiver of all or any part of the Collateral.

Section 4.03 Expenses of Enforcement. The Borrower shall pay to the Mortgagee on demand any and all reasonable expenses (including reasonable attorneys’ fees and legal expenses and including the allocated costs of Mortgagee’s in-house counsel and legal staff) which may have been incurred by the Mortgagee, with interest (i) in the prosecution or defense of any action growing out of or connected with the subject matter of this Mortgage, the Secured Obligations, the Collateral or any of the Mortgagee’s rights therein or thereto; or (ii) in connection with the custody, preservation, use, operation, preparation for sale or sale of any of the Collateral or in connection with obtaining possession of any of the Collateral or otherwise exercising any of Mortgagee’s rights and remedies pursuant to this Mortgage, the incurring of all of which are hereby authorized to the extent the Mortgagee deems the same advisable. The Borrower’s liability to the Mortgagee for any such payment with interest shall be included in the Secured Obligations. The Borrower, to the extent of its rights in the Collateral, waives and releases any right to require the Mortgagee to collect any of the Secured Obligations from any other Collateral (as defined under the Credit Agreement) or any other collateral then held by the Mortgagee under any theory of marshaling of assets or otherwise.

Section 4.04 Waiver of Appraisement, Etc. The Borrower agrees, to the fullest extent that it lawfully may, that it will not (and hereby irrevocably waives its right to) at any time plead, or claim the benefit or advantage of, any appraisement, valuation, stay, extension, moratorium or redemption law now or hereafter in force, in order to prevent or hinder the enforcement of this Mortgage or the absolute sale of the Collateral.

Section 4.05 Waiver of Claims. To the maximum extent permitted by Applicable Law, Borrower waives all claims, damages, and demands against Mortgagee, its Affiliates, agents, and the officers and employees of any of them arising out of the repossession, retention or sale of any Collateral and any other acts or failure to act in connection with Mortgagee’s rights and remedies hereunder, except such as are determined in a final judgment by a court of competent jurisdiction to have arisen out of the gross negligence or willful misconduct of such Person.

G-11

Section 4.06 Additional Waivers. Borrower waives: (a) all right to require Mortgagee to proceed against any other person including any other borrower hereunder or under the Credit Agreement or to apply any Collateral Mortgagee may hold at any time or to pursue any other remedy, Collateral, endorsers or guarantors may be released, substituted or added without affecting the liability of Borrower hereunder; (b) the defense of the Statute of Limitations in any action upon any obligations of Borrower secured hereby; (c) any right of subrogation and any right to participate in Collateral until all obligations secured hereby have been paid in full; and (d) to the fullest extent permitted by law, any right to oppose the appointment of a receiver or similar official to operate Borrower’s business after the occurrence and during the continuance of an Event of Default.

Section 4.07 Remedies Cumulative, No Waiver. No remedy herein conferred upon the Mortgagee is intended to be exclusive of any other remedy, but every such remedy shall be cumulative and shall be in addition to every other remedy herein conferred or now or hereafter existing in law. The exercise by the Mortgagee of any one right or remedy shall not be deemed a waiver or release of or any election against any other right or remedy, and the Mortgagee may proceed against the Borrower or any other Person and the Collateral and any other collateral granted by the Borrower to the Mortgagee under any other agreement, all in any order and through any available remedies. A waiver on any one occasion shall not be construed as a waiver or bar on any future occasion. All property of any kind held at any time by the Mortgagee as Collateral shall stand as one general continuing collateral security for all the Secured Obligations and may be retained by the Mortgagee as security until all the Secured Obligations are fully satisfied.

Section 4.08 Application of Proceeds. Proceeds of any sale, lease or other disposition or other realization upon any Collateral pursuant to this Mortgage and all other sums realized or held by the Mortgagee under this Mortgage or any proceedings hereunder (including any proceeds of insurance) shall be applied by any Credit Facility Lender or Non-Lender upon receipt as set forth in the Credit Agreement.

Section 4.09 Delay or Omission; Possession of Notes.

(a) No delay or omission of the Mortgagee to exercise any right or remedy arising upon the happening of any Default or Event of Default shall impair any right or remedy or shall be construed to be a waiver of any such Default or Event of Default or an acquiescence therein; and every right and remedy given to the Mortgagee by this Article IV or by applicable law may be exercised from time to time and as often as may be deemed expedient by the Mortgagee.

(b) All rights of action under this Mortgage may be enforced by the Mortgagee without the possession of any Note(s) or any other instrument or document evidencing any obligation or the production thereof in any proceeding.

The Borrower hereby irrevocably appoints the Mortgagee the true and lawful attorney of the Borrower for the duration of this Mortgage (with full power of substitution) in the name, place and stead of, and at the expense of, the Borrower in connection with the enforcement of the rights and remedies provided for in this Article IV: (a) to

Except for item (i) above, the power of attorney granted hereby may not be exercised unless an Event of Default has occurred and is continuing and Mortgagee has notified Borrower that it will enforce its security interest in the Collateral if such notice is specifically required under the applicable Loan Documents (including pursuant to any notice and cure rights). The appointment of Mortgagee as Borrower’s attorney-in-fact, and each and every one of Mortgagee’s rights and powers, being coupled with an interest, is irrevocable until all of the Secured Obligations have been fully repaid and performed. MORTGAGEE AND ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, LENDERS OR REPRESENTATIVES SHALL NOT BE RESPONSIBLE TO BORROWER OR ANY OTHER PERSON FOR ANY ACT OR FAILURE TO ACT PURSUANT TO THE POWERS GRANTED UNDER THE POWER OF ATTORNEY HEREIN OR OTHERWISE, EXCEPT FOR ITS OR THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, NOR FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

ANY INTEREST CREATED BY THIS MORTGAGE HEREIN IS EFFECTIVE TO CONSTITUTE AN “INTERNATIONAL INTEREST” WITHIN THE MEANING OF THE CAPE TOWN CONVENTION AND IS LEGALLY SUFFICIENT UNDER APPLICABLE LAW TO CREATE VALID AND ENFORCEABLE RIGHTS, OBLIGATIONS AND INTERESTS OF THE TYPE IT PURPORTS TO CREATE.

(b) BORROWER HEREBY CONSENTS AND AGREES, PURSUANT TO SECTION 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, THAT THE STATE OR FEDERAL COURTS LOCATED IN STATE OF NEW YORK AND SITTING IN THE COUNTY OF NEW YORK OR SOUTHERN DISTRICT OF NEW YORK, RESPECTIVELY, SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN BORROWER AND MORTGAGEE PERTAINING TO THIS MORTGAGE OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS MORTGAGE OR ANY OF THE OTHER LOAN DOCUMENTS; PROVIDED, THAT MORTGAGEE AND BORROWER ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF COUNTY OF NEW YORK OR SOUTHERN DISTRICT OF NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS MORTGAGE SHALL BE DEEMED OR OPERATE TO PRECLUDE MORTGAGEE FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE

BORROWER EXPRESSLY SUBMITS AND CONSENTS TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BORROWER HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. BORROWER HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE TO BORROWER AS SET FORTH IN SECTION 6.2 AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE BORROWER’S ACTUAL RECEIPT THEREOF.

(c) TO THE EXTENT PERMITTED BY LAW, IN CONNECTION WITH ANY ACTION OR PROCEEDING, WHETHER BROUGHT IN STATE OR FEDERAL COURT, BORROWER AND MORTGAGEE EACH HEREBY EXPRESSLY, INTENTIONALLY AND DELIBERATELY WAIVE ANY RIGHT SUCH PARTY MAY OTHERWISE HAVE TO A TRIAL BY JURY.

(d) To the extent permitted by law, service of process in any action against the Borrower or the Mortgagee may be made by registered or certified mail, return receipt requested, to its address indicated herein.

(e) The Borrower agrees that any final judgment rendered against it in any action or proceeding shall be conclusive as to the subject of such final judgment and may be enforced in other jurisdictions in any manner provided by law.

Section 6.05 Severability. The invalidity of any one or more of the provisions of this Mortgage shall not affect the remaining provisions of this Mortgage; if any one or more of the provisions of this Mortgage should be held by any court of law to be invalid, or should operate to render this Mortgage invalid or to impair the lien and security interest of this Mortgage on all or the major portion of the property intended to be mortgaged hereunder, this Mortgage shall be construed as if such provisions had not been contained therein.

Section 6.06 Entire Agreement. This Mortgage (including all exhibits hereto) and the documents executed pursuant hereto constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior agreements, commitments, understandings or inducements (oral or written, expressed or implied), and may not be modified, altered or amended except by a written agreement signed by Borrower and Mortgagee.

Section 6.07 Counterparts. This Mortgage may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. No modification or waiver of any provision hereof shall be effective unless the same is in writing and signed by the party against whom its enforcement is sought.

G-17

Section 6.08 Credit Agreement to Control. In the event of a conflict between the terms of this Mortgage and the terms of the Credit Agreement, the terms of the Credit Agreement shall control.

Section 6.09 Section Titles. The Section titles and Table of Contents contained in this Mortgage and any other Loan Document are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

Section 6.10 Time of the Essence. Time is of the essence for performance of any obligations under this Mortgage.

Section 6.11 Termination and Release.

(a) Full Release. Upon the earlier to occur of (i) payment in full of all Secured Obligations (other than contingent obligations which by their nature cannot be satisfied by payment at such time) and either (x) expiration of the term of the Credit Agreement or (y) termination of the obligation of any Credit Facility Lender and Non-Lender to make any advances to Borrower pursuant to the Credit Agreement or any other Loan Document; or (ii) release by the Mortgagee of the Lien created hereunder in accordance with the terms and conditions of this Mortgage, the Credit Agreement and the other Loan Documents, this Mortgage, and all of the powers, rights and interests granted hereunder and created hereby shall forthwith terminate, and the Mortgagee shall, at the cost and expense of the Borrower, execute and deliver all such documents and instruments reasonably necessary to accomplish the same, within a reasonable period of time.

(b) Partial Release. Notwithstanding paragraph (a), the Borrower shall be entitled to have any item of Collateral released from this Mortgage, which partial releases shall be in form reasonably satisfactory to Mortgagee, for the following reasons: (i) for sale or other disposal of Collateral in accordance with the Credit Agreement; or (ii) to allow the relevant Collateral to be pledged to another lender in connection with the incurrence of Debt permitted under Sections 7.9.4 and 7.10.4 of the Credit Agreement, but solely to the extent the Lien created herein shall be required to be released and not subordinated as a condition thereof (and the Borrower shall use reasonable efforts to require such subordination in lieu of release). If any item of Collateral released pursuant to the foregoing is then the subject of a Lease from the Borrower and if the lessee has deposited with the Borrower any related cash, letter of credit, guaranty or security deposit, maintenance reserve or other cash deposit that does not constitute payment of rental under the relevant Lease, then at the time of release of the relevant Collateral the Mortgagee shall also release the related cash deposit and letter of credit. Notwithstanding the foregoing, the Borrower shall not be entitled to a release of any item of Collateral unless, at the time of such release: (i) the Borrower complies with all requirements set forth in the Credit Agreement regarding the sale, disposal or other transfer of such Collateral and in any other Loan Document; (ii) there is not then existing an Default or Event of Default; and (iii) no Default, Event of Default or Overadvance would exist immediately following the release.

Pledgor shall pay prior to delinquency all taxes, charges, liens and assessments against any of the Collateral and, upon Pledgor’s failure to do so, Security Agent may, at its option, pay such charges and shall be the sole judge of the legality and validity thereof and the amount so paid shall become an Obligation hereunder.

7. Representations and Warranties. For so long as any Obligations remain outstanding, Pledgor represents and warrants that: (a) Pledgor shall have full power to enter into and perform this Agreement and has taken all necessary action to authorize the execution, delivery and performance of this Agreement; (b) this Agreement constitutes the legal, valid and binding obligation of Pledgor, enforceable in accordance with its terms, subject to bankruptcy, insolvency or other similar laws affecting the rights of creditors generally; (c) the execution, delivery and performance of this Agreement will not violate any law, treaty or regulation applicable to Pledgor, any order or decree of any court, arbitrator or governmental agency, or any contractual undertaking to which Pledgor is a party or by which Pledgor may be bound; (d) no consents, licenses, approvals or authorizations of, exemptions by or registrations or declarations with, any governmental authority are required with respect to this Agreement; provided that a precautionary Form 8E should be filed with the Companies Registration Office in Dublin within 21 days of the execution of this Agreement; (e) all of the Pledged Shares are fully paid, non-assessable and validly issued; (f) Pledgor shall have title to the Collateral free and clear of all liens and encumbrances except the interests created hereby; and (g) Security Agent shall have the absolute and unqualified right to sell, at public or private sale, or otherwise dispose of the Collateral, in whole or in part, without restriction, contingent only upon the conditions set forth in this Agreement.

For purposes of defining security interest perfection, Pledgor further agrees that any Collateral which is in transit to Security Agent shall be deemed to be in Security Agent’s possession. Pledgor warrants and represents that none of the Collateral constitutes margin securities for the purposes of Regulations G, T, U or X.

9. Events Of Default. It shall be an “Event of Default” under this Agreement upon the occurrence of any Event of Default as defined in the Credit Agreement, or if Pledgor breaches any representation, warranty, covenant or provision hereof.

(ii) Sell or otherwise assign, give an option or options to purchase or dispose of and deliver the Collateral (or contract to do so), or any part thereof, in one or more parcels at public or private sale or sales, at any exchange, broker’s board or at any of the Security Agent’s offices or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash, on credit or for future delivery without assumption of any credit risk, free of any claim or right of whatsoever kind (including any right or equity of redemption) of Pledgor, which claim, right and equity are hereby expressly waived and released. Security Agent shall have the right to the extent permitted by Applicable Law, upon any such sale or sales, public or private, to purchase the whole or any part of the Collateral so sold; provided, however, Pledgor shall not receive any net proceeds, if any, of any such credit sale or future delivery until cash proceeds are actually received by Security Agent (which cash proceeds shall be applied by Security Agent to the Obligations) and after all Obligations have been paid in full. In case of any sale of all or any part of the Collateral on credit or for future delivery, the Collateral so sold may be retained by Security Agent until the selling price is paid by the purchaser thereof, but Security Agent shall incur no liability in case of the failure of such purchaser to pay for the Collateral so sold and, in case of such failure, the Collateral may again be sold as herein provided.

(b) Any notice required to be given by Security Agent of a sale of the Collateral, or any part thereof, or of any other intended action by Security Agent, which occurs not less than twenty (20) days prior to such proposed action, shall constitute commercially reasonable and fair notice to Pledgor thereof. No notification need be given to the Pledgor if it

H-4

has signed, after the occurrence of an Event of Default, a statement renouncing or modifying any right to notification of sale or other intended disposition.

(c) Security Agent shall not be obligated to make any sale or other disposition of the Collateral, or any part thereof unless the terms thereof shall, in its sole discretion, be satisfactory to it. Security Agent may, if it deems it reasonable, postpone or adjourn the sale of any of the Collateral, or any part thereof, from time to time by an announcement at the time and place of such sale or by announcement at the time and place of such postponed or adjourned sale, without being required to give a new notice of sale. Pledgor agrees that Security Agent has no obligations to preserve rights against prior parties to the Collateral.

(d) Pledgor acknowledges and agrees that Security Agent may comply with limitations or restrictions in connection with any sale of the Collateral in order to avoid any violation of Applicable Law or in order to obtain any required approval of the sale or of the purchase thereof by any governmental regulatory authority or official and, without limiting the generality of the foregoing, Pledgor acknowledges and agrees that Security Agent may be unable to effect a public sale of any or all of the Collateral by reason of certain prohibitions contained in the federal securities laws and applicable state securities laws, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale. Notwithstanding any such circumstances, Pledgor acknowledges and agrees that such compliance shall not result in any such private sale for such reason alone being deemed to have been made in a commercially unreasonable manner. Security Agent shall not be liable or accountable to Pledgor for any discount allowed by reason of the fact that the Collateral is sold in compliance with any such limitation or restriction. Security Agent shall not be under any obligation to delay a sale of any of the Collateral for the period of time necessary to permit the issuer of such securities to register such securities for public sale under the federal securities laws, or under applicable state securities laws, even if the issuer desires, requests or would agree to do so.

(e) Any cash held by Security Agent as Collateral and all cash proceeds received by the Security Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Security Agent, be held by Security Agent as Collateral for the Obligations and/or then or at any time thereafter applied, without any marshalling of rights, remedies or assets, and after payment of any amounts payable to Security Agent hereunder and, after deducting all reasonable costs and expenses of every kind in connection with the care, safekeeping, collection, sale, delivery or otherwise of any or all of the Collateral or in any way relating to the rights of Security Agent hereunder (including attorneys’ fees and costs), to the payment of reduction of the Obligations. Any surplus of such cash or cash proceeds held by Security Agent and remaining after payment in full of all the Obligations shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus.

11. Term. Upon the earlier to occur of (i) the satisfaction in full of all of the Obligations and the expiration of the term of the Credit Agreement and/or the termination of the

H-5

obligation of any Credit Facility Lender or Non-Lender to make any advances or Loans to Pledgor pursuant to the Credit Agreement or any other Loan Documents or (ii) release by the Security Agent of the Lien created hereunder in accordance with the terms and conditions of the Credit Agreement, all of the powers, rights and interests granted hereunder and created hereby shall forthwith terminate, and the Security Agent shall, at the cost and expense of the Pledgor, return to Pledgor all stock certificates and other documents relating to this Agreement, together with any further documents necessary to establish that the pledge given herein is terminated.

12. Notices. All notices and other communications under this Agreement shall be in writing and shall be deemed to have been given three (3) days after deposit in the mail, first class mail, postage prepaid, or one (1) day after being entrusted to a reputable commercial overnight delivery service, or when sent out by facsimile transmission addressed to the party to which such notice is directed at its address determined as provided in this Section.

Pledgor agrees that the rights of any such Holder hereunder or with respect to the related Obligations shall not be subject to any defense, set off or counterclaim that Pledgor may assert or claim against Security Agent, and that any such Holder shall have all of the Security Agent’s rights hereunder but none of the Security Agent’s obligations. Security Agent shall have an unimpaired right to enforce this Agreement for its benefit with respect to that portion of the Obligations which Security Agent has not sold, assigned, transferred participated, pledged or otherwise disposed of.

PLEDGOR HEREBY CONSENTS AND AGREES, PURSUANT TO SECTION 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, THAT THE STATE OR FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN PLEDGOR AND SECURITY AGENT PERTAINING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS; PROVIDED, THAT SECURITY AGENT AND PLEDGOR ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK, NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE SECURITY AGENT FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE OBLIGATIONS, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF SECURITY AGENT. PLEDGOR EXPRESSLY SUBMITS AND CONSENTS TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND PLEDGOR HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON

H-7

CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT.

17. Severability. The invalidity of any one or more of the provisions of this Agreement shall not affect the remaining provisions of this Agreement; if any one or more of the provisions of this Agreement should be held by any court of law to be invalid, or should operate to render this Agreement invalid or to impair the lien and security interest of this Agreement on all or the major portion of the property intended to be mortgaged hereunder, this Agreement shall be construed as if such provisions had not been contained therein.

I-3

has or at any time in the future may acquire any right, title or interest, excluding, however, any and all Excluded Payments (collectively, the “Collateral”):

(2) to the extent not otherwise included, all Proceeds and products of any and all of the foregoing (including, without limitation, proceeds of the sale of the Equipment).

(b) So long as an Event of Default has not occurred and is not continuing, the Owner Participant shall be entitled to remain in full possession, enjoyment and control of the Collateral and to manage and use the same and each part thereof with the same rights and franchises appertaining thereto; provided always that the possession, use, enjoyment and control of the Collateral shall at all times be subject to the terms of this Pledge Agreement and the other Loan Documents and the Lien and security interest granted hereunder and thereunder.

3. Limitations on Security Agent’s Obligations. Anything herein to the contrary notwithstanding, the Owner Participant and the Owner Trustee shall remain liable under each of the agreements constituting part of or relating to the Beneficial Interest to observe and perform all the conditions and obligations to be observed and performed by them thereunder, all in accordance with the terms and provisions thereof. The Security Agent shall have no obligation or liability under any of the agreements constituting part of or relating to the Beneficial Interest by reason of or arising out of this Pledge Agreement or the receipt by the Security Agent of any payment relating thereto pursuant hereto, nor shall the Security Agent be obligated in any manner to perform any of the obligations of the Owner Participant under or pursuant to any of the agreements constituting part of or relating to the Beneficial Interest, to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party under any of the agreements constituting part of or relating to the Beneficial Interest, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

4. Representations and Warranties. The Owner Participant hereby represents and warrants that:

(a) Title; No Other Liens. Except for the Lien granted to the Security Agent pursuant to this Pledge Agreement and Permitted Liens, the Owner Participant has not granted any Lien in, or other claims in respect of, the Collateral. No security agreement, financing statement or other public notice with respect to all or any part of the Collateral has been placed by the Owner Participant on file or of record in any public office, except such as may have been filed in favor of the Security Agent pursuant to this Pledge Agreement or another Loan Document.

I-4

(b) Perfected First Priority Liens. The Owner Participant will take such action within the United States as the Security Agent reasonably determines necessary in order to perfect a first priority Lien in the Collateral in favor of the Security Agent.

(c) Contracts. Other than consents obtained and delivered to the Security Agent pursuant to the Credit Agreement, to the Owner Participant’s knowledge no consent of any party (other than the Owner Participant and the Owner Trustee) is required, or purports to be required, in connection with the execution, delivery and performance of this Pledge Agreement. Assuming the due authorization, execution and delivery by the other parties thereto, each of the agreements constituting part of the Beneficial Interest to which the Owner Participant is a party is in full force and effect and constitutes a valid and legally enforceable obligation of the Owner Participant, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally. No consent or authorization of, filing with or other act by or in respect of any Governmental Authority applicable to it is required in connection with the execution, delivery and performance by the Owner Participant or the validity or enforceability against the Owner Participant of any of the agreements constituting part of the Beneficial Interest other than those which have been duly obtained, made or performed. Neither the Owner Participant nor (to the best of the Owner Participant’s knowledge) any other party to any of the agreements constituting part of the Beneficial Interest is in default in the performance or observance of any of the terms thereof. The Owner Participant has fully performed all obligations owing up to this date under each of the agreements constituting part of the Beneficial Interest. The right, title and interest of the Owner Participant in, to and under each of the agreements constituting part of the Beneficial Interest are not subject to any defense, offset, counterclaim or claim which would materially adversely affect the value of such agreements as Collateral, nor have any of the foregoing been asserted or alleged against the Owner Participant as to any of the agreements constituting part of or relating to the Beneficial Interest. The Owner Participant has delivered to the Security Agent a complete and correct copy of each of the agreements constituting part of or relating to the Beneficial Interest, including all amendments, supplements and other modifications thereto.

5. Covenants. The Owner Participant covenants and agrees with the Security Agent that, from and after the date of this Pledge Agreement until the Secured Obligations are paid in full or the Lien created hereunder is released or terminated in accordance with the terms hereof:

(a) Further Documentation. At any time and from time to time, upon the written request of the Security Agent, and at the sole expense of the Owner Participant, the Owner Participant will promptly and duly execute and deliver such further instruments and documents and take such further action as the Security Agent may reasonably request for the purpose of obtaining or preserving the full benefits of this Pledge Agreement and of the rights and powers herein granted, including, without limitation, the filing of any financing or continuation statements under the Uniform Commercial Code in effect in the applicable jurisdiction with respect to the Liens created hereby. A carbon, photographic or other reproduction of this Pledge Agreement shall be sufficient as a financing statement for filing in any jurisdiction.

(b) Expenses of Enforcement. The Owner Participant shall pay to the Security Agent on demand any and all reasonable expenses (including reasonable attorneys’ fees and legal

I-5

expenses) which may have been incurred by the Security Agent, with interest (i) in the prosecution or defense of any action growing out of or connected with the subject matter of this Pledge Agreement, the Secured Obligations, the Collateral or any of the Security Agent’s rights therein or thereto; or (ii) in connection with the custody, preservation, use, operation, preparation for sale or sale of any of the Collateral or in connection with obtaining possession of any of the Collateral, the incurring of all of which are hereby authorized to the extent the Security Agent deems the same advisable. The Owner Participant’s liability to the Security Agent for any such payment with interest shall be included in the Secured Obligations. The Proceeds of any Collateral received by the Security Agent at any time before or after default, whether from a sale or other disposition of Collateral or otherwise, or the Collateral itself, may be applied to the payment in full or in part of such of the Secured Obligations and in such order and manner as the Security Agent may elect. The Owner Participant, to the extent of its rights in the Collateral, waives and releases any right to require the Security Agent to collect any of the Secured Obligations from any other of the Collateral or any other collateral then held by the Security Agent under any theory of marshaling of assets or otherwise.

(c) Notices. The Owner Participant will advise the Security Agent promptly, in reasonable detail, at its address set forth in the Credit Agreement, of any Lien (other than Liens created hereby or permitted under the Credit Agreement) on, or claim asserted against, any of the Collateral.

(d) No Amendment to Trust Agreement. The Owner Participant will not amend, supplement, modify or terminate the Trust Agreement, or revoke the trust established pursuant to the Trust Agreement, without the Security Agent’s prior written consent; provided, however, that so long as no Event of Default shall have occurred and be continuing, the Owner Participant may, without such consent: (1) amend or supplement the Trust Agreement to add property to the Trust Estate or to substitute Equipment, provided that the terms of the Credit Agreement are complied with in connection with such substitution; (2) amend the Trust Agreement in any manner that does not adversely affect the interests of the Security Agent; and (3) replace the Owner Trustee in accordance with the terms of the Trust Agreement, provided that the successor Owner Trustee agrees in writing to be bound by the terms of this Pledge Agreement, the Owner Trustee Guaranty and the Owner Trustee Mortgage.

(e) Information and Reports. The Owner Participant will promptly furnish or cause to be furnished to the Security Agent such information, reports and records in respect of or relating to the Beneficial Interest as the Security Agent may reasonably request from time to time.

(f) Transfer and Liens. Except as may be permitted by the Credit Agreement, the Owner Participant will not without the prior written consent of the Security Agent sell, transfer, assign or otherwise encumber or dispose of the Beneficial Interest (or any interest or right therein, including but not limited to a transfer of Owner Participant’s interest pursuant to Article VIII of the Trust Agreement) or create or incur any Lien (other than a Permitted Lien) in or upon the Beneficial Interest (or any part thereof).

(g) Books and Records; Inspection. The Owner Participant will faithfully keep or cause to be kept complete and accurate books and records and make all necessary entries

I-6

therein to reflect the quantities, costs, current values and locations of all Collateral, the events and transactions giving rise thereto and all payments, credits and adjustment applicable thereto, shall keep the Security Agent fully and accurately informed as to the locations of all such books and records and shall permit the Security Agent’s agents to have such access to them and to any other records pertaining to the Owner Participant’s business as the Security Agent may request from time to time.

6. Security Agent’s Appointment as Attorney-in-Fact.

(a) Powers. The Owner Participant 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 the Owner Participant and in the name of the Owner Participant or in its own name, from time to time in the Security Agent’s discretion, for the purpose of carrying out the terms of this Pledge Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Pledge Agreement, and, without limiting the generality of the foregoing, the Owner Participant hereby gives the Security Agent the power and right, on behalf of the Owner Participant, without notice to or assent by the Owner Participant, to do the following:

(i) in the case of any Collateral, at any time when any Event of Default shall have occurred and is continuing, in the name of the Owner Participant 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 under any agreement constituting part of the Beneficial Interest or with respect to any other Collateral (including, without limitation, the Trust Estate) and to 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 under any agreement constituting part of the Beneficial Interest or with respect to any other Collateral (including, without limitation, the Trust Estate) whenever payable;

(ii) pay or discharge taxes and Liens (other than Permitted Liens) levied or placed on or threatened against the Collateral or any part thereof; and

(iii) upon the occurrence and during the continuance of any Event of Default (A) 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; (B) ask or demand for, collect, 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; (C) 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 thereof and to enforce any other right in respect of any Collateral; (D) to defend any suit, action or proceeding brought against the Owner Participant with respect to any Collateral; (E) settle, compromise or adjust any suit, action or proceeding described in clause (D) above and, in connection therewith, give such discharges or releases as the Security Agent may deem appropriate; and (F) 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

I-7

were the absolute owner thereof for all purposes, and perform at the Security Agent’s option and the Owner Participant’s expense, at any time, or from time to time, all acts and things which the Security Agent deems necessary to protect, preserve or realize upon the Collateral and the Security Agent’s Liens thereon and to effect the intent of this Pledge Agreement, all as fully and effectively as the Owner Participant might do.

This power of attorney is a power coupled with an interest and shall be irrevocable. The Security Agent agrees not to exercise its rights under this Section 6(a) unless an Event of Default then exists or when doing so would be inconsistent with the acknowledgment and agreement made by the Security Agent under Sections 5.01 and 5.02 of the Mortgage for the benefit of the Lessee.

(b) Other Powers. The Owner Participant also authorizes the Security Agent, at any time and from time to time, to execute, in connection with the sale provided for in Section 9 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.

(c) No Duty on Security Agent’s Part. The powers conferred on the Security Agent hereunder are solely to protect the Security Agent’s interests in the Collateral and shall not impose any duty upon the Security Agent to exercise any such powers. The Security Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to the Owner Participant for any act or failure to act hereunder, except for its own gross negligence or willful misconduct.

7. Performance by Security Agent of Owner Participant’s Obligations. If the Owner Participant fails to perform or comply with any of its agreements contained herein and the Security Agent, as provided for by the terms of this Pledge Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the reasonable expenses of the Security Agent incurred in connection with such performance or compliance, together with interest thereon at the Default Rate, shall be payable by the Owner Participant to the Security Agent on demand and shall constitute Secured Obligations secured hereby.

8. Proceeds. It is agreed that if an Event of Default shall occur and be continuing (a) all Proceeds received by the Owner Participant consisting of cash, checks and other near-cash items shall be held by the Owner Participant in trust for the Security Agent, segregated from other funds of the Owner Participant, and shall, forthwith upon receipt by the Owner Participant, be turned over to the Security Agent in the exact form received by the Owner Participant (duly endorsed by the Owner Participant to the Security Agent, if required), and (b) any and all such Proceeds received by the Security Agent (whether from the Owner Participant or otherwise) may, in the sole discretion of the Security Agent, be held by the Security Agent and applied in the manner specified in Section 11 hereof.

9. Remedies. If an Event of Default shall occur and be continuing, the Security Agent may exercise, in addition to all other rights and remedies granted to it in this Pledge Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the Code.

The provisions of this Mortgage shall to the extent permitted by Applicable Law remain in full force and effect and continue to be effective even if: (a) any petition is filed by or against Owner Trustee for liquidation or reorganization; (b) Owner Trustee becomes insolvent or makes an assignment for the benefit of creditors; (c) a receiver or trustee is appointed for all or any significant part of Owner Trustee’s assets; or (d) at any time payment and performance of the Obligations, or any part thereof, is, pursuant to Applicable Law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations and Mortgagee’s Liens in the Collateral shall be reinstated and deemed reduced only by any amount paid and not so rescinded, reduced, restored or returned.

Section 3.08 Loss of Value. The Owner Trustee shall promptly, and in any event within five (5) Business Days, notify the Mortgagee in writing of any event causing any material deterioration, loss or unscheduled depreciation in value of the Collateral and the Owner Trustee’s best estimate of the amount of such deterioration, loss or depreciation.

Section 3.09 Insurance. The Owner Trustee shall bear the risk of each Engine or item of Equipment being destroyed, irreparably damaged or rendered permanently unfit for sale, lease or use or being damaged in part, from any cause whatsoever at any time during the term of this Mortgage, and shall at its own cost and expense, or in the alternative shall cause each Lessee under each applicable Lease to, obtain and keep in full force and effect all risk of physical loss or damage insurance covering each Engine or item of Equipment, wherever the same may be located, insuring against the risks of fire, explosion, theft and such other risks as are customarily insured against by organizations engaged in the same business and similarly situated with the

J-9

Owner Trustee (and specifically including vandalism and malicious mischief coverage), in an amount usually carried by organizations engaged in the same business or similarly situated with the Owner Trustee, and in any event, in kind and form reasonably satisfactory to the Mortgagee. All such policies of insurance shall be written for the benefit of the Owner Trustee as the insured, and Mortgagee and the Administrative Agent shall be named as additional insureds on liability insurance and Mortgagee shall be named as a loss payee on hull insurance, as applicable. Notwithstanding the foregoing or anything to the contrary herein, to the extent any Engine or item of Equipment included in the Collateral hereunder is included in the Borrowing Base, Owner Trustee shall comply with all insurance requirements set forth in the Credit Agreement.

(i) If the Owner Trustee or the applicable Lessee fails to pay any premium on any such insurance, the Mortgagee shall have the right, but shall be under no obligation, to pay such premium for the Owner Trustee’s account. The Owner Trustee shall repay to the Mortgagee on demand all sums which the Mortgagee shall have paid under this section in respect of insurance premiums, with interest thereon and the Owner Trustee’s liability to the Mortgagee for such repayment with interest shall be included in the Obligations. The Owner Trustee hereby assigns to the Mortgagee any return or unearned premium which may be due upon the cancellation for any reason whatsoever of any policy of insurance maintained in respect of the Collateral and hereby directs the insurer to pay the Mortgagee any amount so due. The Owner Trustee’s right to receive payment of any such return or unearned premium and the proceeds of any such insurance shall constitute a part of the Collateral for all purposes hereof. If no Event of Default has occurred and is continuing, the Mortgagee shall pay any such return or unearned premium to the Owner Trustee, provided that all amounts paid by Mortgagee in respect of insurance premiums have been repaid in full with interest.

Section 3.10 Warranties. Owner Trustee warrants: (a) it is and will be the lawful owner of all Collateral free of all Claims, Liens, encumbrances and setoffs whatsoever, other than the security interest granted pursuant hereto; (b) it has the capacity to grant a security interest in Collateral to Mortgagee; (c) all information furnished by Owner Trustee to Mortgagee heretofore or hereafter, whether oral or written, is and will be correct and true as of the date given; and (d) the execution, delivery and performance hereof are within its powers and have been duly authorized.

ARTICLE IV

EVENTS OF DEFAULT AND REMEDIES

Section 4.01 Events of Default and Remedies. The Owner Trustee shall be in default upon the occurrence of an Event of Default as defined under the Credit Agreement.

Section 4.02 Remedies. If any Event of Default has occurred and is continuing,

(i) Mortgagee, at its option, may exercise any rights and remedies provided to Agents under the Credit Agreement and/or available at law or equity, including all rights and remedies provided under the Uniform Commercial Code in any jurisdiction where enforcement is sought, which include but are not limited to, the following: (i) without notice accelerate the maturity of any part or all of the Obligations and terminate any agreement for the

J-10

granting of further credit to Owner Trustee; (ii) sell, lease or otherwise dispose of Collateral at public or private sale; (iii) transfer any Collateral into its own name or that of its nominee; (iv) retain Collateral in satisfaction of the Obligations, with notice of such retention sent to Owner Trustee as required by law; (v) notify any parties obligated on any Collateral consisting of Accounts, Instruments, Chattel Paper, [choses in action?] or the like to make payment to Mortgagee and enforce collection of any Collateral; (vi) file any action or proceeding which Mortgagee deems necessary or appropriate to protect and preserve the right, title and interest of Mortgagee in the Collateral; (vii) exercise its banker’s lien or right of setoff in the same manner as though the credit were unsecured and (viii) apply all or a portion of sums received or collected from or on account of Collateral, including the proceeds of any sales thereof, to the payment of the costs and expenses incurred in preserving and enforcing rights of Mortgagee including reasonable attorneys’ fees (including the allocated costs of Mortgagee’s in-house counsel and legal staff), and after application of such sums to the obligations as set forth in the Credit Agreement, Mortgagee shall account to Owner Trustee for any surplus remaining thereafter, and shall pay such surplus to the party entitled thereto, including any second secured party who has made a proper demand upon Mortgagee and has furnished proof to Mortgagee as requested in the manner provided by law; in like manner, Owner Trustee agrees to pay to Mortgagee without demand any deficiency after any Collateral has been disposed of and proceeds applied as aforesaid.

(ii) Owner Trustee expressly agrees that, subject to Sections 5.01 and 5.02 hereof, Mortgagee may collect, receive, assemble, process, appropriate and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, assign, give an option or options to purchase or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at public or private sale or sales, at any exchange at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. Mortgagee shall have the right upon any such public sale or sales and, to the extent permitted by law, to purchase for the benefit of Mortgagee by credit bid the whole or any part of said Collateral so sold, free of any right or equity of redemption, which equity of redemption Owner Trustee hereby releases. Such sales may be adjourned, or continued from time to time with or without notice. Owner Trustee shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay the Obligations and all other amounts to which Mortgagee is entitled.

(iii) Owner Trustee further agrees, subject to Sections 5.01 and 5.02 hereof, to assemble the Collateral and make it available to Mortgagee at places which Mortgagee shall reasonably select. Until Mortgagee is able to effect a sale, lease, or other disposition of the Collateral and subject to Sections 5.01 and 5.02 hereof, Mortgagee shall have the right to complete, assemble, use or operate the Collateral or any part thereof, to the extent that Mortgagee deems appropriate, for the purpose of preserving such Collateral or its value or for any other purpose. In addition, the Owner Trustee will provide, without cost or expense to the Mortgagee, storage facilities for any such Engine or item of Equipment and will cause such Engine or item of Equipment to be maintained as required by the terms hereof and of the Credit Agreement. Mortgagee shall have no obligation to Owner Trustee to maintain or preserve the rights of Owner Trustee as against third parties with respect to any Collateral while such Collateral is in the possession of Mortgagee.

J-11

(iv) Upon the completion of any sale of any Collateral, full title and (subject to Sections 5.01 and 5.02 hereof) right of possession to the Engine or item of Equipment so sold shall (subject to any retention of title by the Mortgagee as part of the terms of such sale) pass to the accepted purchaser forthwith upon the completion of such sale, and the Owner Trustee shall deliver, in accordance with the instructions of the Mortgagee (including causing the Engine or item of Equipment to be delivered to such airports as the Mortgagee may specify), such Engine or item of Equipment so sold. The Mortgagee is hereby irrevocably appointed the true and lawful attorney of the Owner Trustee, and in its stead, to make all necessary conveyances of an Engine or item of Equipment if so sold. Nevertheless, if so requested by the Mortgagee or by any purchaser, the Owner Trustee shall confirm any such sale or conveyance by executing and delivering all proper instruments of conveyance or releases as may be designated in any such request. If the Owner Trustee shall for any reason fail to deliver such Engine or item of Equipment or any part thereof after demand by the Mortgagee, the Mortgagee (subject to Sections 5.01 and 5.02 hereof) may, without being responsible for loss or damage, except to the extent caused by the gross negligence or willful misconduct of the Mortgagee, (i) obtain a judgment conferring on the Mortgagee the right to immediate possession or requiring the Owner Trustee to deliver immediate possession of all or part of such Engine or item of Equipment to the Mortgagee, to the entry of which judgment the Owner Trustee hereby specifically consents, or (ii) with or, to the fullest extent provided by law, without such judgment, pursue the whole or any part of such Engine or item of Equipment wherever it may be found and enter any of the premises where such Engine or item of Equipment may be and take possession of and remove the same. Upon every such taking of possession, the Mortgagee may (but shall not be obligated to), from time to time, make all such reasonable expenditures for maintenance, insurance, repairs, replacements, alterations, additions and improvements to and of the Engine or item of Equipment as it may deem proper.

(v) The Owner Trustee hereby covenants and agrees that a notice, which shall be sent in accordance with the provisions of the Credit Agreement or this Mortgage, at least ten (10) Business Days before the date of any of the acts described in this Section 4.02 shall be deemed to be reasonable notice of such act and, specifically, reasonable notification of the time and place of any public sale hereunder and reasonable notification of the time after which any private sale or other intended disposition to be made hereunder is to be made.

(vi) Mortgagee shall be entitled, as a matter of right as against the Owner Trustee, without notice or demand and without regard to the adequacy of the security for the Obligations by virtue of this Mortgage or any other collateral or to the solvency of the Owner Trustee, upon the commencement of judicial proceedings by it to enforce any right under this Mortgage, to the appointment of a receiver of all or any part of the Collateral.

Section 4.03 Expenses of Enforcement. The Owner Trustee shall pay to the Mortgagee on demand any and all reasonable expenses (including reasonable attorneys’ fees and legal expenses and including the allocated costs of Mortgagee’s in-house counsel and legal staff) which may have been incurred by the Mortgagee, with interest (i) in the prosecution or defense of any action growing out of or connected with the subject matter of this Mortgage, the Obligations, the Collateral or any of the Mortgagee’s rights therein or thereto; or (ii) in connection with the custody, preservation, use, operation, preparation for sale or sale of any of the Collateral or in connection with obtaining possession of any of the Collateral or otherwise

J-12

exercising any of Mortgagee’s rights and remedies pursuant to this Mortgage, the incurring of all of which are hereby authorized to the extent the Mortgagee deems the same advisable. The Owner Trustee’s liability to the Mortgagee for any such payment with interest shall be included in the Obligations. The Owner Trustee, to the extent of its rights in the Collateral, waives and releases any right to require the Mortgagee to collect any of the Obligations from any other Collateral (as defined under the Credit Agreement) or any other collateral then held by the Mortgagee under any theory of marshaling of assets or otherwise.

Section 4.04 Waiver of Appraisement, Etc. The Owner Trustee agrees, to the fullest extent that it lawfully may, that it will not (and hereby irrevocably waives its right to) at any time plead, or claim the benefit or advantage of, any appraisement, valuation, stay, extension, moratorium or redemption law now or hereafter in force, in order to prevent or hinder the enforcement of this Mortgage or the absolute sale of the Collateral.

Section 4.05 Waiver of Claims. To the maximum extent permitted by Applicable Law, Owner Trustee waives all claims, damages, and demands against Mortgagee, its Affiliates, agents, and the officers and employees of any of them arising out of the repossession, retention or sale of any Collateral and any other acts or failure to act in connection with Mortgagee’s rights and remedies hereunder, except such as are determined in a final judgment by a court of competent jurisdiction to have arisen out of the gross negligence or willful misconduct of such Person.

Section 4.06 Additional Waivers. Owner Trustee waives: (a) all right to require Mortgagee to proceed against any other person including any other borrower hereunder or under the Credit Agreement or to apply any Collateral Mortgagee may hold at any time or to pursue any other remedy, Collateral, endorsers or guarantors may be released, substituted or added without affecting the liability of Owner Trustee hereunder; (b) the defense of the Statute of Limitations in any action upon any obligations of Owner Trustee secured hereby; (c) any right of subrogation and any right to participate in Collateral until all obligations secured hereby have been paid in full; and (d) to the fullest extent permitted by law, any right to oppose the appointment of a receiver or similar official to operate Owner Trustee’s business after the occurrence and during the continuance of an Event of Default.

Section 4.07 Remedies Cumulative, No Waiver. No remedy herein conferred upon the Mortgagee is intended to be exclusive of any other remedy, but every such remedy shall be cumulative and shall be in addition to every other remedy herein conferred or now or hereafter existing in law. The exercise by the Mortgagee of any one right or remedy shall not be deemed a waiver or release of or any election against any other right or remedy, and the Mortgagee may proceed against the Owner Trustee or any other Person and the Collateral and any other collateral granted by the Owner Trustee to the Mortgagee under any other agreement, all in any order and through any available remedies. A waiver on any one occasion shall not be construed as a waiver or bar on any future occasion. All property of any kind held at any time by the Mortgagee as Collateral shall stand as one general continuing collateral security for all the Obligations and may be retained by the Mortgagee as security until all the Obligations are fully satisfied.

J-13

Section 4.09 Delay or Omission; Possession of Notes.

(i) No delay or omission of the Mortgagee to exercise any right or remedy arising upon the happening of any Default or Event of Default shall impair any right or remedy or shall be construed to be a waiver of any such Default or Event of Default or an acquiescence therein; and every right and remedy given to the Mortgagee by this Article IV or by applicable law may be exercised from time to time and as often as may be deemed expedient by the Mortgagee.

(ii) All rights of action under this Mortgage may be enforced by the Mortgagee without the possession of any Note(s) or any other instrument or document evidencing any obligation or the production thereof in any proceeding.

Section 4.10 Power of Attorney. The Owner Trustee hereby irrevocably appoints the Mortgagee the true and lawful attorney of the Owner Trustee for the duration of this Mortgage (with full power of substitution) in the name, place and stead of, and at the expense of, the Owner Trustee in connection with the enforcement of the rights and remedies provided for in this Article IV: (a) to give any necessary receipts or acquittances for amounts collected or received hereunder, (b) to make all necessary transfers of the Engines or Equipment in connection with any sale, lease or other disposition made pursuant hereto, (c) to execute and deliver for value all necessary or appropriate bills of sale, assignments and other instruments in connection with any such sale, lease or other disposition, the Owner Trustee hereby ratifying and confirming all that such attorney (or any substitute) shall lawfully do hereunder and pursuant hereto, (d) to sign any agreements, orders or other documents in connection with or pursuant to any Lease, (e) to endorse Owner Trustee’s name on any checks, notices, acceptances, money orders, drafts, or other forms of payment or security that may come into Mortgagee’s possession; (f) to receive, open, and retain all mail addressed to Owner Trustee relating to the Collateral, (g) to make, settle, and adjust all claims under Owner Trustee’s policies of insurance and make all determinations and decisions with respect to such policies of insurance relating to the Collateral, (h) to settle and adjust disputes and claims respecting the Accounts directly with Account Debtors, for amounts and upon terms which Mortgagee determines to be reasonable, and Mortgagee may cause to be executed and delivered any documents and releases which Mortgagee determines to be necessary, and (i) to sign the name of Owner Trustee on any document to be executed, recorded or filed in order to perfect or continue perfected Mortgagee’s Lien upon the Collateral if Owner Trustee fails to do so promptly after request therefor by Mortgagee, including filing any financing or continuation statement without the signature of Owner Trustee to the extent permitted by Applicable Law. Except for item (i) above, the power of attorney granted hereby may not be exercised unless an Event of Default has occurred and is continuing and Mortgagee has notified Owner Trustee that it will enforce its security interest in the Collateral if such notice is specifically required under the applicable Loan Documents (including pursuant to any notice and cure rights). The appointment of Mortgagee as Owner

J-14

Trustee’s attorney-in-fact, and each and every one of Mortgagee’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and performed. MORTGAGEE AND ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, LENDERS OR REPRESENTATIVES SHALL NOT BE RESPONSIBLE TO BORROWER OR ANY OTHER PERSON FOR ANY ACT OR FAILURE TO ACT PURSUANT TO THE POWERS GRANTED UNDER THE POWER OF ATTORNEY HEREIN OR OTHERWISE, EXCEPT FOR ITS OR THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, NOR FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

Section 6.04 Governing Law; Choice of Forum; Service of Process.

(a) IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, THIS MORTGAGE AND THE OBLIGATIONS ARISING HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE, INCLUDING SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, BUT OTHERWISE WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES, AND ANY APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. ANY INTEREST CREATED BY THIS MORTGAGE HEREIN IS EFFECTIVE TO CONSTITUTE AN “INTERNATIONAL INTEREST” WITHIN THE MEANING OF THE CAPE TOWN CONVENTION AND IS LEGALLY SUFFICIENT UNDER APPLICABLE LAW TO CREATE VALID AND ENFORCEABLE RIGHTS, OBLIGATIONS AND INTERESTS OF THE TYPE IT PURPORTS TO CREATE.

(b) BORROWER HEREBY CONSENTS AND AGREES, PURSUANT TO SECTION 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, THAT THE STATE OR FEDERAL COURTS LOCATED IN THE STATE OF NEW YORK AND SITTING IN THE COUNTY OF NEW YORK OR SOUTHERN DISTRICT OF NEW YORK, RESPECTIVELY, SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN BORROWER AND MORTGAGEE PERTAINING TO THIS MORTGAGE OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS MORTGAGE OR ANY OF THE OTHER LOAN DOCUMENTS; PROVIDED, THAT MORTGAGEE AND BORROWER ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF COUNTY OF NEW YORK OR SOUTHERN DISTRICT OF NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS MORTGAGE SHALL BE DEEMED OR OPERATE TO PRECLUDE MORTGAGEE FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE OBLIGATIONS DUE UNDER THE CREDIT FACILITY, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR SUCH OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF MORTGAGEE. BORROWER EXPRESSLY SUBMITS AND CONSENTS TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BORROWER HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF

J-18

PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. BORROWER HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE TO BORROWER AS SET FORTH IN SECTION 6.2 AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE BORROWER’S ACTUAL RECEIPT THEREOF.

(c) TO THE EXTENT PERMITTED BY LAW, IN CONNECTION WITH ANY ACTION OR PROCEEDING, WHETHER BROUGHT IN STATE OR FEDERAL COURT, OWNER TRUSTEE AND MORTGAGEE EACH HEREBY EXPRESSLY, INTENTIONALLY AND DELIBERATELY WAIVE ANY RIGHT SUCH PARTY MAY OTHERWISE HAVE TO A TRIAL BY JURY.

(d) To the extent permitted by law, service of process in any action against the Owner Trustee or the Mortgagee may be made by registered or certified mail, return receipt requested, to its address indicated herein.

(e) The Owner Trustee agrees that any final judgment rendered against it in any action or proceeding shall be conclusive as to the subject of such final judgment and may be enforced in other jurisdictions in any manner provided by law.

Section 6.05 Severability. The invalidity of any one or more of the provisions of this Mortgage shall not affect the remaining provisions of this Mortgage; if any one or more of the provisions of this Mortgage should be held by any court of law to be invalid, or should operate to render this Mortgage invalid or to impair the lien and security interest of this Mortgage on all or the major portion of the property intended to he mortgaged hereunder, this Mortgage shall be construed as if such provisions had not been contained therein.

Section 6.06 Entire Agreement. This Mortgage (including all exhibits hereto) and the documents executed pursuant hereto constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior agreements, commitments, understandings or inducements (oral or written, expressed or implied), and may not be modified, altered or amended except by a written agreement signed by Owner Trustee and Mortgagee.

Section 6.07 Counterparts. This Mortgage may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. No modification or waiver of any provision hereof shall be effective unless the same is in writing and signed by the party against whom its enforcement is sought.

Section 6.08 Credit Agreement to Control. In the event of a conflict between the terms of this Mortgage and the terms of the Credit Agreement or the Owner Trustee Guaranty, the terms of the Credit Agreement and the Owner Trustee Guaranty shall control.

NOW, THEREFORE, in consideration of the foregoing premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Guarantor hereby makes the following representations and warranties to the Security Agent and covenants and agrees with the Security Agent as follows:

1. Continuing and Unconditional Guaranty. The Guarantor hereby irrevocably, unconditionally and absolutely guaranties to and for the Security Agent, for the ratable benefit of Credit Facility Lenders and Non-Lenders, the due performance, including without limitation the prompt payment when due or within any applicable grace period, whether at stated maturity, upon acceleration or otherwise and at all times thereafter of any and all Obligations of the Borrower under the Credit Agreement and any other agreements or Loan Documents referred to therein, or under any renewals, extensions or modifications thereof (the “Obligations”) irrespective of (a) any lack of enforceability of any Obligation, (b) any change of the time, manner, place of payment, or any other term of any Obligation, (c) any exchange, release or non-perfection of any collateral securing payment of any Obligation, (d) any law, regulation or

The Guarantor agrees that its liability hereunder shall be immediate and shall not be contingent upon the exercise or enforcement by the Security Agent, the Administrative Agent or the Lenders of whatever remedies each may have against the Borrower or the enforcement of any lien or realization upon any security the Security Agent, the Administrative Agent or the Lenders may at any time possess. The Guarantor agrees that any release which may be given by the Security Agent, the Administrative Agent or the Lenders to the Borrower shall not release the Guarantor; and the Guarantor waives the benefit of any statute of limitations affecting its liabilities hereunder or the enforcement hereof. This Guaranty is a guaranty of payment and not of collection.

If, absent the provisions of this paragraph, this Guaranty would be held or determined to be void, invalid or unenforceable on account of the amount of the Guarantor’s aggregate liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the aggregate amount of such liability shall, without any further action by the Guarantor, the Security Agent, the Administrative Agent, any Lender or Non-Lender or any other Person, be automatically limited and reduced to the highest amount which is valid and enforceable as determined in such action or proceeding, which (without limiting the generality of the foregoing) may be an amount which is not greater than the greater of the excess of the amount of the fair saleable value of the assets of the Guarantor over the amount of all liabilities of the Guarantor (all as determined in accordance with applicable federal and state laws governing determinations of the insolvency of debtors), (a) as of the date hereof, and (b) as of the date of the enforcement of this Guaranty. Nothing contained in this paragraph shall be deemed to waive, diminish or modify the Guarantor’s representations, acknowledgments or recitals set forth herein or in any other Loan Document.

The Guarantor agrees that its obligations as a guarantor shall not be impaired, modified, changed, released, or limited in any manner whatsoever by any impairment, modification, change, release or limitation of the liability of the Borrower or its estate in bankruptcy, resulting from the operation of any present or future provision of the bankruptcy laws or other similar statute, or from the decision of any court in a bankruptcy proceeding. Notwithstanding any provision herein to the contrary, the Obligations shall include all amounts that would otherwise constitute Obligations but for the fact that they are unenforceable or not allowable due to the existence of any proceedings or taking of any actions under any such laws. The Obligations shall not be considered indefeasibly paid for purposes of this Guaranty unless and until all payments to the Administrative Agent, on behalf of itself, the Security Agent and the Lenders, are no longer subject to any right on the part of any Person, including the Borrower, the Borrower as a debtor in possession, or any trustee (whether appointed under the Bankruptcy Code or otherwise) of the Borrower’s assets to invalidate or set aside such payments or to seek to recoup the amount of such payments or any portion thereof, or to declare same to be fraudulent or preferential. Until such full and final performance and indefeasible payment of the Obligations whether by Guarantor or the Borrower, the Security Agent and the Administrative Agent shall have no obligation whatsoever to transfer or assign their interest in the Loan Documents to the Guarantor. In the event that, for any reason, any portion of such payments to the Security Agent and the Administrative Agent on behalf of itself, the Security Agent and the Lenders, is set aside or

K-2

restored, whether voluntarily or involuntarily, after the making thereof, then the obligation intended to be satisfied thereby shall be revived and continued in full force and effect as if said payment or payments had not been made, and the Guarantor shall be liable for the full amount the Security Agent, the Administrative Agent or any Lender or Non-Lender is required to repay plus any and all costs and expenses (including reasonable attorneys’ fees) paid by the Security Agent, the Administrative Agent or any Lender or Non-Lender in connection therewith.

To the maximum extent permitted by law, the Guarantor hereby waives any right to revoke this Guaranty as to future indebtedness. If such a revocation is effective notwithstanding the foregoing waiver, the Guarantor acknowledges and agrees that (a) no such revocation shall be effective until written notice thereof has been received by the Security Agent, (b) no such revocation shall apply to any Obligations in existence on such date (including, any subsequent continuation, extension, or renewal thereof, or change in the interest rate, payment terms, or other terms and conditions thereof), (c) no such revocation shall apply to any Obligations made or created after such date to the extent made or created pursuant to a legally binding commitment of the Security Agent or the Administrative Agent in existence on the date of such revocation, (d) no payment by the Guarantor, the Borrower, or from any other source, prior to the date of such revocation shall reduce the maximum obligation of the Guarantor hereunder, except to the extent of such payment, and (e) any payment by the Borrower or from any source other than the Guarantor, subsequent to the date of such revocation, shall first be applied to that portion of the Obligations as to which the revocation is effective and which are not, therefore, guaranteed hereunder, and to the extent so applied shall not reduce the maximum obligation of the Guarantor hereunder.

This is a continuing guaranty and shall remain in full force and effect and be binding upon the Guarantor, its successors and assigns until payment in full of all the Obligations.

2. Payment of Obligations. In furtherance of, and not limiting the Guarantor’s obligations pursuant to Section 1 hereof, upon the occurrence of an Event of Default under the Credit Agreement (which Event of Default has not been waived in writing by Security Agent) any demand by the Security Agent upon the Guarantor for payment of any amount in respect of any Obligation, the Guarantor shall immediately pay the Obligation or Obligations demanded (as determined pursuant to Section 1 hereof) in lawful currency of the United States of America and in same day funds to the office of the Security Agent as set forth in the Credit Agreement, or to such other location as the Security Agent may from time to time specify. Notwithstanding anything to the contrary contained herein or elsewhere, it shall not be necessary for the Security Agent to make any demand upon or bring any legal, equitable or other action, institute suit, exhaust its rights against the Borrower or any other guarantor of the Borrower, or proceed, enforce or exhaust its rights against any security given to secure payment of the Obligations.

3. Waiver. The Guarantor hereby waives all notices of any character whatsoever with respect to this Guaranty and the Obligations, including but not limited to notice of the acceptance hereof and reliance hereon, of the present existence or future incurring of any Obligations, of the amounts, terms and conditions thereof, and of any defaults thereon, and further waives the defenses of diligence, presentment for payment, protest, demand or extensions of time for payment. The Guarantor hereby consents to the taking of, or failure to take, from time to time without notice to the Guarantor, any such action of any nature

K-3

whatsoever with respect to the Obligations and with respect to any rights against any Person or Persons or in any property, including but not limited to any renewals, extensions, modifications, postponements, compromises, settlements, substitutions, refusals or failures to exercise or enforce, indulgences, waivers, surrenders, exchanges and releases, and the Guarantor will remain fully liable hereon notwithstanding any of the foregoing. The Guarantor hereby waives the benefit of all laws now or hereafter in effect in any way limiting or restricting its liability hereunder, including without limitation: (a) except for the defense of payment made on account of the Obligations to the Security Agent or the Administrative Agent or any Lender or Non-Lender, all defenses whatsoever (legal or equitable) to the Guarantor’s liability hereunder including (i) defenses, set-offs, counterclaims or claims that Guarantor may have against Borrower or any other party liable to the Security Agent or the Administrative Agent or any Lender or Non-Lender and (ii) any defense, set-off, counterclaim or claim of any kind or nature, arising directly or indirectly from the present or future lack of perfection, sufficiency, validity or enforceability of the Obligations or any security therefor; (b) all right to stay of execution and exemption of property in any action to enforce its liability hereunder; (c) all rights accorded it under any other statutory provisions of any other applicable jurisdiction affecting the rights of the Security Agent to enforce the obligations of the Guarantor under this Guaranty; (d) all notice of any adverse change in the financial condition of the Borrower or of any other fact that might increase Guarantor’s risk; (e) any defense based upon or arising out of an election of remedies by the Security Agent; (f) the benefit of any statute of limitations affecting the Guarantor’s liability hereunder or the enforcement thereof (and any act which shall defer or delay the operation of any statute of limitations applicable to the Obligations shall similarly operate to defer or delay the operation of such statute of limitations applicable to the Guarantor’s liability hereunder); and (g) all rights and defenses arising out of an election of remedies by the Security Agent, even though that election of remedies may have the effect of destroying the Guarantor’s rights of subrogation and reimbursement against the Borrower.

To the maximum extent permitted by law, Guarantor hereby waives any right of subrogation or reimbursement Guarantor has or may have as against the Borrower with respect to the Obligations, until the Obligations have been indefeasibly paid in full. In addition, Guarantor hereby waives any right to proceed against the Borrower, now or hereafter, for contribution, indemnity, reimbursement, and any other suretyship rights and claims, whether direct or indirect, liquidated or contingent, whether arising under express or implied contract or by operation of law, which Guarantor may now have or hereafter have as against the Borrower with respect to the Obligations. Guarantor also hereby waives any rights to recourse to or with respect to any asset of the Borrower. Guarantor agrees that in light of the immediately foregoing waivers, the execution of this Guaranty shall not be deemed to make Guarantor a “creditor” of the Borrower, and that for purposes of Sections 547 and 550 of the Bankruptcy Code, Guarantor shall not be deemed a “creditor” of the Borrower.

WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER PROVISION SET FORTH IN THIS GUARANTY, GUARANTOR HEREBY WAIVES, TO THE MAXIMUM EXTENT PERMITTED BY LAW, ANY AND ALL SURETYSHIP RIGHTS, BENEFITS, SANCTIONS OR DEFENSES ARISING DIRECTLY OR INDIRECTLY UNDER ANY APPLICABLE LAW.

Assuming due authorization, execution and delivery of this Guaranty and each of the other Loan Documents by each of the parties thereto (other than the Guarantor), this Guaranty and each of the other Loan Documents to which it is a party is a legal, valid and binding obligation of the Guarantor, enforceable against the Guarantor in accordance with its respective terms, except as enforcement may be limited by the Bankruptcy Code of the United States of America, as amended from time to time, and all other applicable liquidation, conservatorship, bankruptcy, moratorium, rearrangement, receivership, insolvency, reorganization, or similar debtor relief Laws from time to time in effect affecting the rights of creditors generally.

(c) Loan Documents. The Guarantor further represents and warrants to the Security Agent that the Guarantor has read and understands the terms and conditions of the Loan Documents.

5. Covenants. The Guarantor covenants and agrees that from and after the date hereof and so long as Obligations remain unpaid or outstanding:

The Guarantor shall maintain its corporate existence under and in compliance with all applicable laws and conduct its business in all material respects in accordance with all applicable laws binding on it and its operations or assets and perform its obligations under the Loan Documents to which it is a party.

K-5

(c) No Security Interest. The Guarantor agrees not to create, incur, assume or suffer to exist any Lien attributable to Guarantor on the Equipment or the other Collateral (excluding any Liens specifically permitted under the Loan Documents), and shall take all necessary action to remove and release any such Lien and shall reimburse and indemnify the Security Agent, and each other party to any of the Loan Documents, for any loss incurred as a result of any such Lien.

(d) No Amendment to Trust Agreement. The Guarantor, in its individual capacity, agrees to perform its obligations under the Trust Agreement and further agrees not to amend, supplement, modify or terminate the Trust Agreement, or revoke the Trust, without the Security Agent’s prior written consent except as permitted by Section 5(d) of the Beneficial Interest Pledge Agreement.

(e) No Other Business. In its capacity as trustee for Borrower, the Guarantor has engaged in no business activity and will engage in no other business activities, except in respect of the transactions contemplated by the Loan Documents, and has incurred no indebtedness other than as contemplated by the Loan Documents.

(f) Indebtedness. The Guarantor will not contract for, create, incur or assume any indebtedness (including contingent

liability therefor), grant any credit, guarantee any debts or grant any indemnity other than pursuant to the Loan Documents or as otherwise expressly permitted by the Loan Documents.

(g) Sale or Assignment. Except as expressly permitted by the Credit Agreement and the other Loan Documents and/or upon receipt of written instructions from Security Agent, the Guarantor will not sell, assign, transfer or otherwise dispose of the Equipment or the other Collateral (or any portion thereof).

6. Subordination of Sums Payable to Any Guarantor. The Guarantor hereby subordinates all claims and demands it has, or may in the future have, against the Borrower arising or growing out of any indebtedness, liability or obligation, direct or indirect, due or to become due which arises, may arise or arose by reason of any advance or loan by the Guarantor, directly or indirectly, to the Borrower, but excluding any compensation from time to time accrued and owed to Guarantor from Borrower, as such compensation is permitted under Section 6.07 of the Trust Agreement (all of such claims and demands being herein referred to collectively as the “Subordinated Liabilities”), to the prior and full payment, performance, satisfaction and discharge of the Obligations, and the Guarantor agrees that the Security Agent shall first be paid in full with interest all sums now due or that may hereafter accrue and become due and payable by the Borrower under the Credit Agreement, the Notes and any other Loan Document before the Guarantor shall be paid anything by the Borrower or out of any property of the Borrower for or on account of any of the Subordinated Liabilities. The Guarantor further agrees that the Security Agent, the Administrative Agent or any Lender or Non-Lender may at any time and from time to time renew or extend the time of payment of any indebtedness of the Borrower to the Security Agent, the Administrative Agent or any Lender or Non-Lender, or any portion of such indebtedness, and may make new loans to the Borrower, secured or unsecured, under the Credit Agreement or otherwise, with or without a guarantee, all without any notice to the Guarantor who shall nonetheless remain fully bound by its agreement to subordinate the

K-6

Subordinated Liabilities until this Guaranty has been terminated by the Security Agent in the manner hereinafter provided.

7. Expenses. In addition to all other liabilities of the Guarantor hereunder, the Guarantor also agree to pay to the Security Agent, on demand, all reasonable costs and expenses (including reasonable fees, costs and disbursements of its counsel) which may be incurred in the enforcement of the Obligations or the liabilities of the Guarantor hereunder.

condition relating to any or all the Obligations may be changed, the Borrower (or any other Person primarily or secondarily liable for the Obligations, including the Guarantor hereunder) may be discharged from any or all the Obligations, any composition or settlement relating thereto may be consummated and accepted, and that the Guarantor will remain bound upon this Guaranty notwithstanding any or all of the foregoing.

9. No Waivers; No Election; Rights and Remedies Cumulative. No failure on the part of the Security Agent to exercise, and no delay in exercising, any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by the Security Agent of any right, power or remedy preclude any other further exercise thereof or the exercise of any other right, power or remedy. Subject to the terms of Section 17 hereof, the Security Agent shall have the right to seek recourse against the Guarantor to the fullest extent provided for herein, and no election by the Security Agent to proceed in one form of action or proceeding, or against any party, or on any obligation, shall constitute a waiver of the Security Agent’s right to proceed in any other form of action or proceeding or against other parties unless the Security Agent has expressly waived such right in writing. Specifically, but without limiting the generality of the foregoing, no action or proceeding by the Security Agent, the Administrative Agent or any Lender or Non-Lender under any Loan Document or any other document or instrument evidencing the Obligations shall serve to diminish the liability of the Guarantor under this Guaranty except to the extent that the Security Agent, the Administrative Agent or any Lender or Non-Lender finally and unconditionally shall have realized indefeasible payment by such action or proceeding. The rights and remedies provided herein shall be in addition to and not exclusive of any rights or remedies provided at law or in equity, and may be exercised in such order as the Security Agent shall determine, in its sole discretion.

10. Other Guaranties. A subsequent or concurrent guaranty by any other guarantor of any of the Obligations shall not be deemed to be in lieu of or to supersede or terminate this Guaranty but shall be construed as an additional or supplementary guaranty; and if any other guarantor has given to the Security Agent a previous guaranty or guaranties, this Guaranty shall be construed to be an additional or supplementary guaranty, and not to be in lieu thereof or to terminate such previous guaranty or guaranties.

11. Right of Set-off. Upon an Event of Default under the Credit Agreement (which Event of Default is not waived in writing by Security Agent), the Security Agent, the Administrative Agent and each Lender and Non-Lender are hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set-off and apply any and all deposits at any time

K-7

held and other indebtedness at any time owing by the Security Agent, the Administrative Agent and any Lender or Non-Lender to or for the credit of the Guarantor against any and all of the obligations of the Guarantor now or hereafter existing under this Guaranty. Any such set-off or application of deposits by a Lender or Non-Lender shall be deemed to be made on behalf of all of the Lenders, in accordance with their respective Pro Rata Shares.

12. Termination of Guaranty. This Guaranty shall terminate and be of no further force and effect upon the earliest to occur of the following: (a) payment in full of all Obligations (other than contingent obligations which by their nature cannot be satisfied by payment at such time) and either (i) expiration of the term of the Credit Agreement or (ii) termination of the obligation of any Credit Facility Lender and Non-Lender to make any advances to Owner Participant pursuant to the Credit Agreement or any other Loan Document or (b) transfer of the Beneficial Interest contemplated by the Trust Agreement to (i) WLFC Funding Corporation or (ii) any other Subsidiary of the Borrower pursuant to any contribution agreement or similar agreement entered into in connection with a securitization transaction similar to the transactions contemplated by the WEST Funding Facility; provided that any such transfer made in connection with this Subsection 12(b) shall occur only with the express written consent of Security Agent, which consent may be withheld in Security Agent’s sole discretion.

13. Binding Effect; Assignment. The provisions of this Guaranty shall be binding upon and inure to the benefit of the Guarantor and the Security Agent and their respective successors and assigns, except that the Guarantor may not assign or otherwise transfer any of its rights or obligations hereunder.

14. Amendments and Waivers. None of the terms or provisions of this Guaranty may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the then-existing Guarantor and Security Agent, provided, that any provision of this Guaranty may be waived by the Security Agent in a written letter or agreement executed by the Security Agent or by facsimile transmission from the Security Agent, and any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

15. Governing Law; Choice of Forum; Service of Process.

GUARANTOR EXPRESSLY SUBMITS AND CONSENTS TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND GUARANTOR HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. GUARANTOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE TO GUARANTOR AS SET FORTH IN SECTION 15(d) HEREOF AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE GUARANTOR’S ACTUAL RECEIPT THEREOF.

(c) TO THE EXTENT PERMITTED BY LAW, IN CONNECTION WITH ANY ACTION OR PROCEEDING, WHETHER BROUGHT IN STATE OR FEDERAL COURT, GUARANTOR AND SECURITY AGENT EACH HEREBY EXPRESSLY, INTENTIONALLY AND DELIBERATELY WAIVE ANY RIGHT SUCH PARTY MAY OTHERWISE HAVE TO A TRIAL BY JURY.

5. Covenants.

5.1 The Assignor hereby covenants with the Assignee that:

(t) it will do or permit to be done each and every act or thing which the Assignee may from time to time reasonably require to be done for the purpose of enforcing the Assignee’s rights in relation to the Assigned Property and under this Assignment;

(u) except as permitted by the Head Lease, the Sub-Lease, the Credit Agreement and the other Loan Documents (as defined in the Credit Agreement) and this Assignment, it will not transfer, assign, sell, dispose of or otherwise alienate, nor will it create or permit to exist any mortgage, charge, pledge lien or other security interest whatsoever, howsoever created or arising, over any of its rights, title, benefit or interest under the Assigned Property;

(v) following the occurrence of an Event of Default which is continuing the Assignor will not without the prior written consent of the Assignee, not to be unreasonably withheld or delayed, amend or modify any provision of the Sub-Lease which would in any way be prejudicial to the Assignee’s rights or agree or purport to do so.

6. Assignor Acknowledgements.

6.1 It is agreed that notwithstanding the provisions of this Assignment:

(a) the Assignor shall at all times remain liable to perform all the duties and obligations of the Assignor in relation to the Assigned Property to the same extent as if this Assignment had not been executed;

L-6

(b) the exercise by the Assignee of any of the rights assigned hereunder shall not release the Assignor from any of its duties or obligations to the Sub-Lessee under the Sub-Lease except to the extent that such exercise by the Assignee shall constitute performance of such duties and obligations;

(c) the Assignee shall not have any obligation or liability under the Assigned Property by reason of, or arising out of, this Assignment or be obliged to perform any of the obligations or duties of the Assignor under the Assigned Property or to make any payment or to present or file any claim or to take any other action to collect or enforce any claim for any payment assigned hereunder;

(d) for so long as no Event of Default by the Assignor in the payment or discharge of any of the Secured Obligations shall have occurred and be continuing, the Assignor shall continue to be entitled to exercise its rights and powers under the Sub-Lease but at any time following the occurrence and during the continuance of an Event of Default the Assignee shall be entitled to notify the Sub-Lessee that the Assignee’s rights as assignee have become exercisable, and after the delivery of such notice, during the continuance of such Event of Default, all such rights and powers shall be exercisable only by the Assignee;

(e) the Assignee shall not be obliged to make any enquiry as to the nature or sufficiency of any payment made under the Assigned Property or received by it hereunder or to make any claim or take any other action to collect any monies or to enforce any rights and benefits hereby assigned to the Assignee or to which the Assignee shall be entitled;

(f) the Assignee shall not be responsible in any way whatsoever in the event that the exercise by the Assignor of any of its rights or powers under the Assigned Property may be adjudged improper or to constitute a breach or repudiation of the Assigned Property by the Assignor; and

(g) in the event of any circumstances whereby further performance of the Sub-Lease becomes impossible or unlawful or is otherwise frustrated, such impossibility, unlawfulness or frustration shall not affect the validity of any payments already received by the Assignee pursuant to this Assignment.

7. Power of Attorney. As security for the performance of the Secured Obligations and for conferring on the Assignee the benefit of the rights expressed to be conferred under this Assignment, the Assignor irrevocably appoints and constitutes the Assignee as the Assignor’s true and lawful attorney with full power (in the name of the Assignor or otherwise) to carry out any of the Assignor’s obligations under this Assignment, to ask, require, demand, receive, compound and give acquittance for any and all monies and advises for monies due or to become due, under or arising out of, the Sub-Lease or the Assigned Property, to enforce any provision thereof, to give valid receipts and discharges, to endorse any cheques or other installments or orders in connection therewith, and generally to file any claims or take any action or institute any proceedings which may seem necessary or advisable to the Assignee, for the purpose of putting into effect the intent of this Assignment. The powers conferred on the Assignee by this Clause shall only be exercisable by the Assignee following the occurrence and during the continuance of an Event of Default in payment or discharge of the Secured Obligations, but no

L-7

party dealing with the Assignee as such attorney shall be bound to enquire as to whether this condition has in fact been satisfied.

8. Application of Proceeds. If any sum paid or recovered in respect of the liabilities of the Assignor under this Assignment is less than the amount then due, the Assignee may apply that sum in accordance with the provisions of the Credit Agreement.

9. Continuing Security. The security hereby constituted shall be a continuing security and shall not be discharged by reason of any matter which would otherwise discharge the Assignor from its obligations hereunder including without limitation, any variation of or amendment to any of the Transaction Documents, except as provided for in Clause 3.3 above.

10. Further Assurance. The Assignor agrees at any time and from time to time, upon the request of the Assignee, to execute and deliver promptly and duly to the Assignee any and all such further instruments and documents which the Assignee may reasonably require, or which are required by law, for obtaining the full benefits of this Assignment and the Assigned Property and of the rights and powers herein granted.

11. Compliance. If the Assignor fails to comply with any provision of this Assignment, the Assignee may, without being in any way obliged to do so, or responsible for so doing and without prejudice to its ability to treat that non-compliance as a default by the Assignor in the payment or discharge of any of the Secured Obligations effect compliance on the Assignor’s behalf, whereupon the Assignor will become liable to pay immediately on receipt of written demand therefor any sums reasonably expended by the Assignee together with all reasonable costs and expenses (including reasonable legal costs) in connection therewith, together with interest, at the Post-Default Rate (without deduction, both after and before judgment) from the date of the Assignee’s expenditure until payment.

12. Delays, Waivers, Rights Cumulative. No failure to exercise, and no delay on the part of the Assignee in exercising, any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise of any right, power or privilege preclude the further exercise thereof.

The rights and remedies herein provided are cumulative and not exclusive of any rights or remedies provided by law.

13. Notices.

13.1 Any notice or other communication to be given under or for the purposes of this Assignment shall be in writing and shall be treated as properly served or given if hand delivered or sent by registered post, reputable courier or facsimile (subject, in the case of facsimile transmission, to the sender having posted a copy of the facsimile transmission to the notice address of the recipient on the date of transmission (but without prejudice to Clause 13.3)) to the relevant person at the following address or facsimile number (or such other address or facsimile number) as that person may have designated in writing from time to time to the person giving the notice):

SUBSIDIARY GUARANTY

THIS SUBSIDIARY GUARANTY, dated as of November 18, 2009 (as amended, modified or supplemented from time to time, the “Guaranty”), made by each of the undersigned guarantors (each, a “Guarantor” and, together with any other entity that becomes a guarantor hereunder, the “Guarantors”), for the benefit of UNION BANK, N.A. (the “Security Agent”), in its capacity as Security Agent for itself and on behalf of the Credit Facility Lenders and Non-Lenders under the Credit Agreement (as defined below).

Preliminary Statement

WHEREAS, Willis Lease Finance Corporation (the “Borrower”), Union Bank, N.A., together with any other Lenders from time to time (collectively, the “Lenders”) and Union Bank, N.A., as Administrative Agent, Swing Line Lender, Issuing Lender, and Security Agent have entered into that certain Credit Agreement, dated as of November 18, 2009 (as amended, restated, modified or supplemented from time to time, the “Credit Agreement”). All capitalized terms used herein and not otherwise defined shall have the respective meanings ascribed to them in the Credit Agreement;

WHEREAS, each Guarantor is a direct or indirect wholly owned subsidiary of the Borrower, and the Borrower will use a portion of the proceeds of the Loans to finance or re-finance the operation of each such Guarantor and, consequently, each Guarantor will benefit from the extension of credit to the Borrower pursuant to the Credit Agreement;

WHEREAS, it is a condition to the making of any Loan under the Credit Agreement that this Guaranty be executed and delivered by each Guarantor in favor of the Security Agent and be in continuous full force and effect; and

NOW, THEREFORE, in consideration of the foregoing premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, each Guarantor hereby makes the following representations and warranties to the Security Agent and covenants and agrees with the Security Agent as follows:

1. Continuing and Unconditional Guaranty. Each Guarantor, jointly and severally, hereby irrevocably, unconditionally and absolutely guaranties to and for the Security Agent for itself and on behalf of the Credit Facility Lenders and Non-Lenders the due performance, including, without limitation, the prompt payment when due or within any applicable grace period, whether at stated maturity, upon acceleration or otherwise and at all times thereafter of any and all obligations of the Borrower owed to the Security Agent, the Administrative Agent or any Credit Facility Lender under the Credit Agreement, the Notes, and any other Loan Documents referred to therein, or under any renewals, extensions or modifications thereof (the “Obligations”) irrespective of (a) any lack of enforceability of any Obligation, (b) any change of the time, manner, place of payment, or any other term of any Obligation, (c) any exchange, release or non-perfection of any collateral securing payment of any Obligation, (d) any law, regulation or order of any jurisdiction affecting the genuineness, validity, or rights of the Security Agent or the

M-1

Administrative Agent or the Credit Facility Lenders with respect to the Obligations or any instruments evidencing any of the Obligations, or (e) any other circumstance which might otherwise constitute a defense to or discharge of any Guarantor. Each Guarantor agrees that the obligations of each Guarantor hereunder are independent of the obligations of the Borrower or any other Guarantor, and that a separate action may be brought against each Guarantor whether or not such action is brought against the Borrower or any other Guarantor or whether or not the Borrower or any other Guarantor is joined in such action. Each Guarantor agrees that its liability hereunder shall be immediate and shall not be contingent upon the exercise or enforcement by the Security Agent, Administrative Agent or the Credit Facility Lenders of whatever remedies it may have against the Borrower or any other Guarantor, or the enforcement of any Lien or realization upon any security the Security Agent or the Administrative Agent may at any time possess. Each Guarantor agrees that any release which may be given by the Security Agent or the Administrative Agent or the Credit Facility Lenders to the Borrower or any other Guarantor shall not release such Guarantor; and each Guarantor waives the benefit of any statute of limitations affecting its liabilities hereunder or the enforcement hereof. This Guaranty is a guaranty of payment and not of collection.

If, absent the provisions of this paragraph, this Guaranty would be held or determined to be void, invalid or unenforceable on account of the amount of the Guarantors’ aggregate liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the aggregate amount of such liability shall, without any further action by the Guarantors, the Security Agent, any Credit Facility Lender or any other Person, be automatically limited and reduced to the highest amount which is valid and enforceable as determined in such action or proceeding, which (without limiting the generality of the foregoing) may be an amount which is not greater than the greater of the excess of the amount of the fair saleable value of the assets of the Guarantors on an aggregate basis over the amount of all liabilities of the Guarantors on an aggregate basis (all as determined in accordance with applicable federal and state laws governing determinations of the insolvency of debtors), (a) as of the date hereof, and (b) as of the date of the enforcement of this Guaranty. Nothing contained in this paragraph shall be deemed to waive, diminish or modify the Guarantors’ representations, acknowledgments or recitals set forth herein or in any other Loan Document.

Each Guarantor agrees that its obligations as a guarantor shall not be impaired, modified, changed, released, or limited in any manner whatsoever by any impairment, modification, change, release or limitation of the liability of the Borrower or its estate in bankruptcy, resulting from the operation of any present or future provision of the bankruptcy laws or other similar statute, or from the decision of any court in a bankruptcy proceeding. Notwithstanding any provision herein to the contrary, the Obligations shall include all amounts that would otherwise constitute Obligations but for the fact that they are unenforceable or not allowable due to the existence of any proceedings or taking of any actions under any such laws. The Obligations shall not be considered indefeasibly paid for purposes of this Guaranty unless and until all payments to the Administrative Agent, on behalf of itself, the Security Agent and the Credit Facility Lenders are no longer subject to any right on the part of any Person, including the Borrower, the Borrower as a debtor in possession, or any trustee (whether appointed under the Bankruptcy Code or otherwise) of the Borrower’s assets to invalidate or set aside such payments or to seek to recoup the amount of such payments or any portion thereof, or to declare same to be fraudulent or preferential. Until such full and final performance and indefeasible payment of the Obligations

M-2

whether by any Guarantor or the Borrower, the Administrative Agent, on behalf of itself, the Security Agent and the Credit Facility Lenders shall have no obligation whatsoever to transfer or assign its interest in the Loan Documents to any Guarantor. In the event that, for any reason, any portion of such payments to the Security Agent or the Administrative Agent is set aside or restored, whether voluntarily or involuntarily, after the making thereof, then the obligation intended to be satisfied thereby shall be revived and continued in full force and effect as if said payment or payments had not been made, and the Guarantors shall be liable for the full amount the Security Agent or the Administrative Agent or any Credit Facility Lender is required to repay plus any and all costs and expenses (including reasonable attorneys’ fees) paid by the Security Agent or the Administrative Agent or any Credit Facility Lender in connection therewith.

To the maximum extent permitted by law, each Guarantor hereby waives any right to revoke this Guaranty as to future indebtedness. If such a revocation is effective notwithstanding the foregoing waiver, each Guarantor acknowledges and agrees that (a) no such revocation shall be effective until written notice thereof has been received by the Security Agent, (b) no such revocation shall apply to any Obligations in existence on such date (including, any subsequent continuation, extension, or renewal thereof, or change in the interest rate, payment terms, or other terms and conditions thereof), (c) no such revocation shall apply to any Obligations made or created after such date to the extent made or created pursuant to a legally binding commitment of the Security Agent or the Administrative Agent in existence on the date of such revocation, (d) no payment by any Guarantor, the Borrower, or from any other source, prior to the date of such revocation shall reduce the maximum obligation of the Guarantors hereunder, except to the extent of such payment, and (e) any payment by the Borrower or from any source other than a Guarantor, subsequent to the date of such revocation, shall first be applied to that portion of the Obligations as to which the revocation is effective and which are not, therefore, guaranteed hereunder, and to the extent so applied shall not reduce the maximum obligation of the Guarantors hereunder.

This is a continuing guaranty and shall remain in full force and effect and be binding upon each Guarantor, its successors and assigns until payment in full of all the Obligations.

2. Payment of Obligations. In furtherance of, and not limiting each Guarantor’s obligations pursuant to Section 1 hereof, upon the occurrence of an Event of Default under the Credit Agreement (which Event of Default has not been waived in writing by the Security Agent) and any demand by the Security Agent upon the Guarantors for payment of any amount in respect of any Obligation, the Guarantors shall immediately pay the Obligation or Obligations demanded (as determined pursuant to Section 1 hereof) in lawful currency of the United States of America and in same day funds to the office of the Security Agent as set forth in the Credit Agreement, or to such other location as the Security Agent may from time to time specify. Notwithstanding anything to the contrary contained herein or elsewhere, it shall not be necessary for the Security Agent to make any demand upon or bring any legal, equitable or other action, institute suit, exhaust its rights against the Borrower or any other guarantor of the Borrower, or proceed, enforce or exhaust its rights against any security given to secure payment of the Obligations.

3. Waiver. Each Guarantor hereby waives all notices of any character whatsoever with respect to this Guaranty and the Obligations, including but not limited to notice of the acceptance

M-3

hereof and reliance hereon, of the present existence or future incurring of any Obligations, of the amounts, terms and conditions thereof, and of any defaults thereon, and further waives the defenses of diligence, presentment for payment, protest, demand or extensions of time for payment. Each Guarantor hereby consents to the taking of, or failure to take, from time to time without notice to any Guarantor, any such action of any nature whatsoever with respect to the Obligations and with respect to any rights against any Person or Persons or in any property, including but not limited to any renewals, extensions, modifications, postponements, compromises, settlements, substitutions, refusals or failures to exercise or enforce, indulgences, waivers, surrenders, exchanges and releases, and each Guarantor will remain fully liable hereon notwithstanding any of the foregoing. Each Guarantor hereby waives the benefit of all laws now or hereafter in effect in any way limiting or restricting its liability hereunder, including without limitation: (a) except for the defense of payment made on account of the Obligations to the Security Agent, Administrative Agent or any Credit Facility Lender, all defenses whatsoever (legal or equitable) to such Guarantor’s liability hereunder including (i) defenses, set-offs, counterclaims or claims that any Guarantor may have against Borrower or any other party liable to the Security Agent, Administrative Agent or any Credit Facility Lender and (ii) any defense, set-off, counterclaim or claim of any kind or nature, arising directly or indirectly from the present or future lack of perfection, sufficiency, validity or enforceability of the Obligations or any security therefor; (b) all right to stay of execution and exemption of property in any action to enforce its liability hereunder; (c) all rights accorded it under any other statutory provisions of any other applicable jurisdiction affecting the rights of the Security Agent to enforce the obligations of each Guarantor under this Guaranty; (d) all notice of any adverse change in the financial condition of the Borrower or of any other fact that might increase Guarantor’s risk; and (e) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement thereof (and any act which shall defer or delay the operation of any statute of limitations applicable to the Obligations shall similarly operate to defer or delay the operation of such statute of limitations applicable to such Guarantor’s liability hereunder).

To the maximum extent permitted by law, each Guarantor hereby waives any right of subrogation or reimbursement such Guarantor has or may have as against the Borrower with respect to the Obligations. In addition, each Guarantor hereby waives any right to proceed against the Borrower, now or hereafter, for contribution, indemnity, reimbursement, and any other suretyship rights and claims, whether direct or indirect, liquidated or contingent, whether arising under express or implied contract or by operation of law, which such Guarantor may now have or hereafter have as against the Borrower with respect to the Obligations. Each Guarantor also hereby waives any rights to recourse of or with respect to any asset of the Borrower. Each Guarantor agrees that in light of the immediately foregoing waivers, the execution of this Guaranty shall not be deemed to make such Guarantor a “creditor” of the Borrower, and that for purposes of Sections 547 and 550 of the Bankruptcy Code, such Guarantor shall not be deemed a “creditor” of the Borrower.

4. Representations and Warranties. Each Guarantor, jointly and severally, represents and warrants to the Security Agent as follows:

(a) Organization: Good Standing. It is duly organized and validly existing under the laws of the jurisdiction of its organization, and has the power and authority (corporate or otherwise) necessary to own its assets, carry on its business and enter into and perform its

M-4

obligations hereunder and under the other Loan Documents to which it is a party. It is qualified to do business and, if applicable, is in good standing as a foreign corporation in each jurisdiction in which it is required to so qualify, except where the failure to so qualify would not have a Material Adverse Effect.

(b) Corporate Authority. The making and performance of this Guaranty and the other Loan Documents to which any Guarantor is a party are within such Guarantor’s power and authority and have been duly authorized by all necessary action (corporate or otherwise). The making and performance of this Guaranty and the other Loan Documents to which any Guarantor is a party (i) do not and under present law will not require any consent or approval of any of its shareholders or any other Person, and (ii) do not and under present law will not violate any law, rule, regulation, order, writ, judgment, injunction, decree, determination or award, do not and will not violate any provision of its charter or by-laws or equivalent organizational documents, do not and will not result in any breach of any agreement, lease or instrument to which it is a party, by which it is bound or to which any of its assets are or may be subject. No Guarantor is in default in any material respect under any of the foregoing.

(c) Validity of Documents. This Guaranty and the other Loan Documents to which any Guarantor is a party, if any, are, or when executed and delivered will be, the legal, valid and binding obligation of such Guarantor, enforceable against it in accordance with their terms. Except as has been duly obtained, no authorization, consent, approval, license, exemption of or filing or registration with any court, governmental agency or other tribunal is or under present law will be necessary to the validity or performance of this Guaranty or the other Loan Documents to which any Guarantor is a party, other than particulars of any security document to which Guarantor is a party must be filed on a Form C1 in the Companies Registration Office in Dublin within 21 days of the execution of each such security document.

(d) Financial Condition of Borrower. Each Guarantor is currently informed of the financial condition of the Borrower and of all other circumstances which a diligent inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Each Guarantor further represents and warrants to the Security Agent that such Guarantor has read and understands the terms and conditions of the Loan Documents. Each Guarantor hereby covenants that it will continue to keep informed of the Borrower’s financial condition, the financial condition of other Guarantors, if any, and of all other circumstances which bear upon the risk of nonpayment or nonperformance of the Obligations.

(b) Credit Agreement Affirmative and Negative Covenants.

It will comply with each of the affirmative covenants set forth in Section 6 of the Credit Agreement and the negative covenants set forth in Section 7 of the Credit Agreement, substituting its name for the name of the Borrower throughout the Credit Agreement as fully as if set forth therein without the necessity of restating each and every said covenant herein; provided, however, that in determining a Guarantor’s compliance with the aforementioned covenants of the Credit Agreement (i) Section 7.5(b) of the Credit Agreement shall be deemed to read “the Borrower or a Subsidiary is the surviving entity”; (ii) the terms “Material Adverse Change” and “Material Adverse Effect” as used in the Credit Agreement shall continue to be deemed to refer to the Borrower rather than the Guarantor; (iii) the definition of ‘Permitted Liens” in the Credit Agreement shall be deemed to include those existing Liens described on Schedule I to this Guaranty, and (iv) nothing in the Credit Agreement shall be deemed to prohibit a Guarantor from transferring assets to the Borrower.

6. Subordination of Sums Payable to Any Guarantor. Each Guarantor hereby subordinates all claims and demands it has, or may in the future have, against the Borrower or any other Guarantor arising or growing out of any indebtedness, liability or obligation, direct or indirect, due or to become due which arises, may arise or arose by reason of any advance or loan by such Guarantor, directly or indirectly, to the Borrower or any other Guarantor (all of such claims and demands being herein referred to collectively as the “Subordinated Liabilities”), to the prior and full payment, performance, satisfaction and discharge of the Obligations, and each Guarantor agrees that the Security Agent shall first be paid in full with interest all sums now due or that may hereafter accrue and become due and payable by the Borrower under the Credit Agreement, the Notes and any other Loan Document before any Guarantor shall be paid anything by the Borrower or out of any property of the Borrower for or on account of any of the Subordinated Liabilities. Each Guarantor further agrees that the Security Agent, the Administrative Agent or any Credit Facility Lender may at any time and from time to time renew or extend the time of payment of any indebtedness of the Borrower to the Credit Facility Lenders, or any portion of such indebtedness, and may make new loans to the Borrower, secured or unsecured, under the Credit Agreement or otherwise, with or without a guarantee, all without any notice to the Guarantors who shall nonetheless remain fully bound by their agreement to subordinate the Subordinated Liabilities until this Guaranty has been terminated by the Security Agent in the manner hereinafter provided.

7. Expenses. In addition to all other liabilities of each Guarantor hereunder, the Guarantors also agree to pay to the Security Agent, on demand, all reasonable costs and expenses

(including reasonable fees, costs and disbursements of its counsel) which may be incurred in the enforcement of the Obligations or the liabilities of the Guarantors hereunder.

9. No Waivers: No Election: Rights and Remedies Cumulative. No failure on the part of the Security Agent to exercise, and no delay in exercising, any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by the Security Agent of any right, power or remedy preclude any other further exercise thereof or the exercise of any other right, power or remedy. The Security Agent shall have the right to seek recourse against each Guarantor to the fullest extent provided for herein, and no election by the Security Agent to proceed in one form of action or proceeding, or against any party, or on any obligation, shall constitute a waiver of the Security Agent’s right to proceed in any other form of action or proceeding or against other parties unless the Security Agent has expressly waived such right in writing. Specifically, but without limiting the generality of the foregoing, no action or proceeding by the Security Agent, the Administrative Agent or any Credit Facility Lender under any Loan Document or any other document or instrument evidencing the Obligations shall serve to diminish the liability of any Guarantor under this Guaranty except to the extent that the Security Agent, the Administrative Agent or any Credit Facility Lender finally and unconditionally shall have realized indefeasible payment by such action or proceeding and then only to the extent of such payment. The rights and remedies provided herein shall be in addition to and not exclusive of any rights or remedies provided at law or in equity, and may be exercised in such order as the Security Agent shall determine, in its sole discretion.

10. Other Guaranties. A subsequent guaranty by any other guarantor of any of the Obligations shall not be deemed to be in lieu of or to supersede or terminate this Guaranty but shall be construed as an additional or supplementary guaranty; and if any other guarantor has given to the Security Agent a previous guaranty or guaranties, this Guaranty shall be construed to be an additional or supplementary guaranty, and not to be in lieu thereof or to terminate such previous guaranty or guaranties.

11. Right of Set-off. Upon an Event of Default under the Credit Agreement (which Event of Default has not been waived in writing by the Security Agent), the Security Agent, the Administrative Agent and each Credit Facility Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set-off and apply any and all deposits at any time held and other indebtedness at any time owing by the Security Agent, the Administrative Agent and any Credit Facility Lender to or for the credit of any Guarantor against any and all of the obligations of such Guarantor now or hereafter existing under this Guaranty. Any such set-off or application of deposits by a Credit Facility Lender shall be deemed to be

M-7

made on behalf of all of the Credit Facility Lenders, in accordance with their respective Pro Rata Share of the Revolving Loan Commitment.

12. Termination of Guaranty. Notwithstanding anything to the contrary here or in any other Loan Document, Guarantors shall be released from liability under this Guaranty only upon the earlier to occur of (a) payment in full of all Obligations (other than contingent obligations which by their nature cannot be satisfied by payment at such time) and either (i) expiration of the term of the Credit Agreement or (ii) termination of the obligation of any Credit Facility Lender and Non-Lender to make any advances to Borrower pursuant to the Credit Agreement or any other Loan Document; or (b) release by Security Agent of such Guarantor in accordance with the terms and conditions of this Guaranty, the Credit Agreement and the other Loan Documents.

The Owner Trustee or any successor Owner Trustee may resign at any time without cause by giving at least 60 days’ prior written notice to the Owner Participant, such resignation to be effective upon the acceptance of appointment by the successor Owner Trustee under Section 9.01(b) hereof. In addition, the Owner Participant may at any time remove the Owner Trustee with or without cause by a notice in writing delivered to the Owner Trustee, such removal to be effective upon the acceptance of appointment by the successor Owner Trustee under Section 9.01(b) hereof. In the case of the resignation or

N-8

removal of the Owner Trustee, the Owner Participant may appoint a successor Owner Trustee by an instrument signed by the Owner Participant. If a successor Owner Trustee shall not have been appointed within 30 days after such notice of resignation or removal, the Owner Trustee may apply to any court of competent jurisdiction to appoint a successor Owner Trustee to act until such time, if any, as a successor shall have been appointed as above provided. Any successor Owner Trustee so appointed by such court shall immediately and without further act be superseded by any successor Owner Trustee appointed as above provided.

(b) Execution and Delivery of Documents, etc. Any successor Owner Trustee, however appointed, shall execute and deliver to the predecessor Owner Trustee an instrument accepting such appointment, and thereupon such successor Owner Trustee, without further act, shall become vested with all the estates, properties, rights, powers, duties and trusts of the predecessor Owner Trustee in the trusts hereunder with like effect as if originally named the Owner Trustee herein; but nevertheless, upon the written request of such successor Owner Trustee, such predecessor Owner Trustee shall execute and deliver an instrument transferring to such successor Owner Trustee, upon the trusts herein expressed, all the estates, properties, rights, powers and trusts of such predecessor Owner Trustee, and such predecessor Owner Trustee shall duly assign, transfer, deliver and pay over to such successor Owner Trustee all monies or other property then held by such predecessor Owner Trustee upon the trusts herein expressed. Upon the appointment of any successor Owner Trustee hereunder, the predecessor Owner Trustee will execute such documents as are provided to it by such successor Owner Trustee and will take such further actions as are requested of it by such successor Owner Trustee as are reasonably requested.

(c) Qualifications. Any successor Owner Trustee, however appointed, shall be a “citizen of the United States” within the meaning of 49 U.S.C. § 40102(a)(15) and shall also be a bank or trust company organized under the laws of the United States or any state thereof having a combined capital and surplus of at least $50,000,000, if there be such an institution willing, able and legally qualified to perform the duties of the Owner Trustee hereunder upon reasonable or customary terms. No such successor trustee shall charge fees for its services as an Owner Trustee in excess of the then prevailing market rates for such services.

(d) Merger, etc. Any corporation into which WFB may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which WFB shall be a party, or any corporation to which substantially all the corporate trust business of WFB may be transferred, shall, subject to the terms of Section 9.01(c) hereof, be the Owner Trustee hereunder without further act.

Section 9.02 Co-Trustees and Separate Trustees. If at any time it shall be necessary or prudent in order to conform to any law of any jurisdiction in which all or any part of the Trust Estate is located, or the Owner Trustee being advised by counsel shall determine that it is so necessary or prudent in the interest of the Owner Participant or the Owner Trustee, or the Owner Trustee shall have been directed to do so by the Owner Participant, the Owner Trustee and the Owner Participant shall execute and deliver an agreement supplemental hereto and all other instruments and agreements necessary or proper to constitute another bank or trust company or one or more persons (any and all of which shall be a “citizen of the United States” as defined in 49 U.S.C. § 40102(a)(15)) approved by the Owner Trustee and the Owner Participant, either to

N-9

act as co-trustee, jointly with the Owner Trustee, or to act as separate trustee hereunder (any such co-trustee or separate trustee being herein sometimes referred to as an “additional trustee”). In the event the Owner Participant shall not have joined in the execution of such agreements supplemental hereto within ten days after the receipt of a written request from the Owner Trustee so to do, or in case an Event of Default shall occur and be continuing, the Owner Trustee may act under the foregoing provisions of this Section 9.02 without the concurrence of the Owner Participant; and the Owner Participant hereby appoints the Owner Trustee its agent and attorney-in-fact to act for it under the foregoing provisions of this Section 9.02 in either of such contingencies.

Every additional trustee hereunder shall, to the extent permitted by law, be appointed and act, and the Owner Trustee and its successors shall act, subject to the following provisions and conditions:

(a) All powers, duties, obligations and rights conferred upon the Owner Trustee in respect of the custody, control and management of monies, the Equipment or documents authorized to be delivered hereunder shall be exercised solely by the Owner Trustee;

(b) All other rights, powers, duties and obligations conferred or imposed upon the Owner Trustee shall be conferred or imposed upon and exercised or performed by the Owner Trustee and such additional trustee jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (including the holding of title to the Trust Estate) the Owner Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations shall be exercised and performed by such additional trustee;

(c) No power given to any such additional trustee shall be exercised hereunder by such additional trustee, except jointly with, or with the consent in writing of, the Owner Trustee;

(d) No trustee hereunder shall be personally liable by reason of any action or omission of any other trustee hereunder; and

(e) The Owner Trustee and Owner Participant may remove any such additional trustee, at any time, by an instrument in writing signed by both parties; provided, in the event that the Owner Participant shall not have joined in the execution of any such instrument within ten days after the receipt of a written request from the Owner Trustee so to do, the Owner Trustee shall have the power to remove any such additional trustee without the concurrence of the Owner Participant, and the Owner Participant hereby appoints the Owner Trustee its agent and attorney-in-fact in connection therewith.
