CREDIT AGREEMENT

This CREDIT AGREEMENT is dated as of November 16, 2011 and is entered into by and among Great Lakes Aviation, Ltd., an Iowa corporation (“Great Lakes”), the financial institutions and other entities that are or hereafter become parties to this Agreement as Lenders and Crystal Financial LLC (in its individual capacity, “Crystal” or “Administrative Agent”) and GB Merchant Partners, LLC (in its individual capacity “GB Merchant” or “Collateral Agent”, and together with the Administrative Agent, the “Agents” and each individually an “Agent”).

R E C I T A L S:

WHEREAS, Great Lakes desires that Lenders extend a term credit facility and a revolving credit facility to Great Lakes to fund the repayment of certain indebtedness of Great Lakes owing to Raytheon Aircraft Credit Corp., to provide working capital financing for Great Lakes and to provide funds for other general corporate purposes of Great Lakes;

WHEREAS, Great Lakes desires to secure all of its Obligations (as hereinafter defined) under the Loan Documents (as hereinafter defined) by granting to Collateral Agent, for the benefit of the Lenders, a security interest in and lien upon substantially all of its assets; and

WHEREAS, all capitalized terms herein shall have the meanings ascribed thereto in Annex A hereto which is incorporated herein by reference.

NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, Great Lakes, Lenders and each Agent agree as follows:

SECTION 1.

AMOUNTS AND TERMS OF LOANS

1.1 Loans. Subject to the terms and conditions of this Agreement and in reliance upon the representations and warranties and other agreements of Great Lakes contained herein:

(a) Revolving Loans.

(i) Each Revolving Lender agrees, severally and not jointly, to make available to Great Lakes from time to time until the Maturity Date its Pro Rata Share of revolving loans (each a “Revolving Loan”) requested by Great Lakes hereunder. All Revolving Loans must be in a minimum amount of $500,000 and an aggregate amount that is an integral multiple of $100,000 and no more than one Borrowing of Revolving Loans shall be made per month. The Revolving Loan of any Revolving Lender shall not at any time exceed the lesser of (i) such Revolving Lender’s Revolving Loan Commitment, or (ii) such Revolving Lender’s Pro Rata Share of an amount equal to the lesser of (A) the Maximum Amount and (B) the Borrowing Base.

Anything to the contrary in this Section 1.1(a) notwithstanding, each Agent shall have the right (but not the obligation) to establish, increase, reduce, eliminate, or otherwise adjust reserves from time to time against the Borrowing Base and the Term Loan Formula in such amounts, and with respect to such matters, as each Agent in its Permitted Discretion shall deem necessary or appropriate, including reserves with respect to (A) sums that Great Lakes is required to pay under this Agreement or any other Loan Document (such as taxes, assessments, insurance premiums, or, in the case of leased assets, rents or other amounts payable under such leases) and has failed to pay when due, and (B) amounts owing by Great Lakes or its Subsidiaries to any Person to the extent secured by a Lien on, or trust over, any of the Collateral (other than a Permitted Encumbrance which is a permitted purchase money Lien or the interest of a lessor under a Capital Lease), which Lien or trust, in the Permitted Discretion of each Agent likely would have a priority superior to Collateral Agent’s Liens (such as Liens or trusts in favor of landlords, warehousemen, carriers, mechanics, materialmen, laborers, or suppliers, or Liens or trusts for ad valorem, excise, sales, or other taxes where given priority under applicable law) in and to such item of the Collateral. If, at any time, either Agent establishes or increases reserves against the Borrowing Base or the Term Loan Formula, such Agent will give Great Lakes fifteen (15) days advance written notice of such change, unless a Default or Event of Default then exists, in which case such Agent will give Great Lakes contemporaneous oral or written notice of such change.

(ii) Revolving Loans may be repaid and; provided, that each of the conditions precedent in Section 6.2 hereof is satisfied, reborrowed. All Revolving Loans shall be repaid in full on the Maturity Date (or sooner upon the acceleration of the Loans as provided for in this Agreement). If so requested by a Revolving Lender, Great Lakes shall execute and deliver to such Revolving Lender a note to evidence the Revolving Loan Commitment of such Revolving Lender.

(iii) Each note shall be in the principal amount of the Revolving Loan Commitment of the applicable Revolving Lender, dated the Closing Date and substantially in the form of Exhibit A (each a “Revolving Note” and, collectively, the “Revolving Notes”). Each Revolving Note shall represent the obligation of Great Lakes to pay the amount of the applicable Revolving Lender’s Revolving Loan, together with interest thereon.

(iv) Revolving Loans may be requested with three (3) Business Days prior written notice to each Agent prior to 10:00 a.m. (Mountain time) and no more than one Borrowing of Revolving Loans shall be requested per month. Written notices for funding requests shall be in the form attached as Exhibit B (“Notice of Revolving Loan”) and each Revolving Loan shall be made in accordance with this Agreement.

(b) Term Loan.

(i) Each Term Loan Lender agrees, severally and not jointly, to lend to Great Lakes a term loan on the Closing Date equal to such Term Loan Lender’s Pro Rata Share of the Term Loan Commitment (such loan, the “Term Loan”). Each Term Loan Lender’s Term Loan Commitment shall terminate in full upon the making of the Term Loan on the Closing Date.

(ii) In addition to any other required repayment of the Term Loan, Great Lakes shall repay the Term Loan through periodic payments of principal (“Scheduled Installments”) on the last day of each Fiscal Quarter as follows:


Payment Date	Scheduled Installment
March 31, 2012	$	750,000
June 30, 2012	$	750,000
September 30, 2012	$	750,000
December 31, 2012	$	750,000
March 31, 2013	$	875,000
June 30, 2013	$	875,000
September 30, 2013	$	875,000
December 31, 2013	$	875,000
March 31, 2014	$	1,000,000
June 30, 2014	$	1,000,000
September 30, 2014	$	1,000,000
December 31, 2014	$	1,000,000
March 31, 2015	$	1,125,000
June 30, 2015	$	1,125,000
September 30, 2015	$	1,125,000

Notwithstanding the foregoing, the outstanding principal balance of the Term Loan, shall be due and payable in full on the Maturity Date (or sooner upon the acceleration of the Loans as provided for in this Agreement). Any amount of the Term Loan that is repaid or prepaid may not be reborrowed. If so requested by a Term Loan Lender, Great Lakes shall execute and deliver to such Term Loan Lender a note to evidence the Term Loan held by such Term Loan Lender. Each note shall be in the principal amount of the Term Loan of the applicable Term

Loan Lender, dated the Closing Date and substantially in the form of Exhibit C (each a “Term Note” and, collectively, the “Term Notes”). Each Term Note shall represent the obligation of Great Lakes to pay the amount of the applicable Term Loan Lender’s Term Loan, together with interest thereon.

(i) Notice to Lenders of Borrowing Request. Promptly following receipt by each Agent of a Notice of Revolving Loan, Administrative Agent shall advise each applicable Revolving Lender of such Notice of Revolving Loans and the amount of such Revolving Lender’s Revolving Loan to be made as part of the applicable Borrowing.

(ii) Making of Loans. Each Revolving Lender shall make the amount of such Revolving Lender’s Pro Rata Share of the requested Borrowing available to the Administrative Agent in immediately available funds, to Administrative Agent’s Account, not later than 10:00 a.m. (Mountain time) on the Funding Date applicable thereto. After Administrative Agent’s receipt of the proceeds of such Revolving Loans, Administrative Agent shall make the proceeds thereof available to Great Lakes on the applicable Funding Date by transferring immediately available funds equal to such proceeds received by Administrative Agent to the Disbursement Account; provided, however, that, Administrative Agent shall not request any Revolving Lender to make any Revolving Loan, and no Revolving Lender shall have the obligation to make any Revolving Loan, if (A) one or more of the applicable conditions precedent set forth in Section 6 will not be satisfied on the requested Funding Date for the applicable Borrowing unless such condition has been waived, or (B) the requested Borrowing would exceed the Availability on such Funding Date.

(iii) Unless the Administrative Agent receives notice from an applicable Revolving Lender prior to 9:00 a.m. (Mountain time) on the date of a Borrowing, that such Revolving Lender will not make available as and when required hereunder to Administrative Agent for the account of Great Lakes the amount of that Revolving Lender’s Pro Rata Share of the Borrowing, Administrative Agent may assume that each Revolving Lender has made or will make such amount available to Administrative Agent in immediately available funds on the Funding Date and Administrative Agent may (but shall not be so required), in reliance upon such assumption, make available to Great Lakes on such date a corresponding amount. If any Revolving Lender shall not have made its full amount available to Administrative Agent in immediately available funds and if Administrative Agent in such circumstances has made available to Great Lakes such amount, that Revolving Lender shall on the Business Day following such Funding Date make such amount available to Administrative Agent. A notice submitted by Administrative Agent to any Revolving Lender with respect to amounts owing under this Section shall be conclusive, absent manifest error. If such amount is so made available, such payment to Administrative Agent shall constitute such Revolving Lender’s Revolving Loan on the date of Borrowing for

all purposes of this Agreement. If such amount is not made available to Administrative Agent on the Business Day following the Funding Date, Administrative Agent will notify Great Lakes of such failure to fund and, upon demand by Administrative Agent, Great Lakes shall, within five (5) Business Days, promptly pay such amount to the Administrative Agent for Administrative Agent’s sole account, together with interest thereon for each day elapsed since the date of such Borrowing, at a rate per annum equal to the interest rate applicable at the time to the Revolving Loans.

(iv) Funding Authorization. The proceeds of all Loans made pursuant to this Agreement on and subsequent to the Closing Date are to be funded by Administrative Agent by wire transfer to the account designated by Great Lakes below (the “Disbursement Account”):

Beneficiary Bank: Wells Fargo Bank, N.A.

420 Montgomery St

Great Lakes shall provide Administrative Agent with written notice of any change in the foregoing instructions at least three (3) Business Days before the desired effective date of such change.

(d) Protective Advances.

(i) Protective Advances. Any contrary provision of this Agreement or any other Loan Document notwithstanding, Administrative Agent hereby is authorized by Great Lakes and the Lenders, from time to time, with the consent of the Collateral Agent, (A) after the occurrence and during the continuance of a Default or an Event of Default, or (B) at any time that any of the other applicable conditions precedent set forth in Section 6 are not satisfied, to make Revolving Loans to, or for the benefit of, Great Lakes on behalf of the Revolving Lenders (in an aggregate amount for all such Revolving Loans taken together not exceeding the lesser of (i) $3,000,000 outstanding at any one time and (ii) twenty percent (20.0%) of the Borrowing Base) that Administrative Agent, in its Permitted Discretion deems necessary or desirable (1) to preserve or protect the Collateral,

or any portion thereof, or (2) to enhance the likelihood of repayment of all or any portion of the Obligations (any of the Revolving Loans described in this Section 1.1(d)(i) shall be referred to as “Protective Advances”).

(ii) Each Protective Advance shall be deemed to be a Revolving Loan hereunder, except that prior to Settlement therefor, all payments on the Protective Advances shall be payable to Administrative Agent, as applicable, solely for its own account. The Protective Advances shall be repayable on demand, secured by Collateral Agent’s Liens and constitute Obligations hereunder, and bear interest at the rate applicable from time to time to Revolving Loans. The provisions of this Section 1.1(d) are for the exclusive benefit of Agents and the Lenders and are not intended to benefit Great Lakes in any way.

(e) Settlement. It is agreed that each Revolving Lender’s funded portion of the Revolving Loans is intended by the Revolving Lenders to equal, at all times, such Revolving Lender’s Pro Rata Share of the outstanding Revolving Loans. Such agreement notwithstanding, Administrative Agent and the other Lenders agree (which agreement shall not be for the benefit of Great Lakes) that in order to facilitate the administration of this Agreement and the other Loan Documents, settlement among the Revolving Lenders as to the Revolving Loans and the Protective Advances shall take place on a periodic basis. Administrative Agent shall request settlement (“Settlement”) with the Revolving Lenders on a weekly basis, or on a more frequent basis if so determined by Administrative Agent (1) for itself, with respect to the outstanding Protective Advances, and (2) with respect to Great Lakes or its Subsidiaries’ Collections or payments received, as to each by notifying the Revolving Lenders by, telecopy, telephone, or other similar form of transmission, of such requested Settlement, no later than 2:00 p.m. (Boston time) on the Business Day immediately prior to the date of such requested Settlement (the date of such requested Settlement being the “Settlement Date”). Subject to the terms and conditions contained herein, if the amount of the Revolving Loans (including Protective Advances) made by a Revolving Lender is less than such Revolving Lender’s Pro Rata Share of the Revolving Loans (including Protective Advances) as of a Settlement Date, such Revolving Lender shall no later than 12:00 p.m. (Boston time) on the Settlement Date transfer in immediately available funds to the Administrative Agent’s Account, an amount such that each such Revolving Lender shall, upon transfer of such amount, have as of the Settlement Date, its Pro Rata Share of the Revolving Loans (including Protective Advances). Such amounts made available to Administrative Agent under clause (z) of the immediately preceding sentence shall be applied against the amounts of the applicable Protective Advance and, together with the portion of such Protective Advance representing such Revolving Lender’s Pro Rata Share thereof, shall constitute Revolving Loans of such Revolving Lender. If any such amount is not made available to the Administrative Agent by any Revolving Lender on the Settlement Date applicable thereto to the extent required by the terms hereof, Administrative Agent shall be entitled to recover for its account such amount on demand from such Revolving Lender together with interest thereon.

(f) Independent Obligations. All Loans shall be made by the Lenders contemporaneously and in accordance with their Pro Rata Shares. It is understood that (i) no Lender shall be responsible for any failure by any other Lender to perform its obligation to make any Loan (or other extension of credit) hereunder, nor shall any Commitment of any Lender be increased or decreased as a result of any failure by any other Lender to perform its obligations hereunder, and (ii) no failure by any Lender to perform its obligations hereunder shall excuse any other Lender from its obligations hereunder.

1.2 Interest and Applicable Margins.

(a) Great Lakes shall pay interest to Administrative Agent, for the ratable benefit of Lenders, in accordance with the various Loans being made by each Lender, in arrears on each applicable Interest Payment Date, at the following rates: (i) with respect to Revolving Loans the LIBOR Rate plus the Applicable Revolver LIBOR Margin per annum, and (ii) with respect to the Term Loan, the LIBOR Rate plus the Applicable Term Loan LIBOR Margin per annum.

(b) If any payment on any Loan becomes due and payable on a day other than a Business Day, the maturity thereof will be extended to the next succeeding Business Day and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension.

(c) All computations of Fees calculated on a per annum basis and interest shall be made by Administrative Agent on the basis of a 360 day year, in each case for the actual number of days occurring in the period for which such Fees and interest are payable. Each determination by Administrative Agent of an interest rate and Fees hereunder shall be final, binding and conclusive on Great Lakes, absent manifest error.

(d) So long as an Event of Default has occurred and is continuing, the interest rates applicable to the Loans shall be increased by two percentage points (2%) per annum above the rates of interest otherwise applicable hereunder (“Default Rate”) at the election of either Agent, (or upon the written request of Requisite Lenders), and all outstanding Obligations shall bear interest at the Default Rate applicable to such Obligations. Interest at the Default Rate shall accrue from the initial date of such Event of Default until that Event of Default is cured or waived and shall be payable upon demand, but in any event, shall be payable on the next regularly scheduled payment date set forth herein for such Obligation.

(e) Notwithstanding anything to the contrary set forth in this Section 1.2, if a court of competent jurisdiction determines in a final order that the rate of interest payable hereunder exceeds the highest rate of interest permissible under law (the “Maximum Lawful Rate”), then so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable hereunder shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the rate of interest payable hereunder is less than the Maximum Lawful Rate, Great Lakes shall continue to pay interest hereunder at the Maximum Lawful Rate until such time as the total interest received by Administrative Agent, on behalf of Lenders, is equal to the total interest that would have been received had the interest rate payable hereunder been (but for the operation of this clause) the interest rate payable since the Closing Date as otherwise provided in this Agreement. Thereafter, interest hereunder shall be paid at the rate(s) of interest and in the manner provided in Sections 1.2(a) through (d), unless and until the rate of interest again exceeds the Maximum Lawful Rate, and at that time this clause shall again apply. In no event shall the total interest received by any Lender pursuant to the terms hereof exceed the amount that such Lender could lawfully have received had the interest due hereunder been calculated for the full term hereof at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated pursuant to this

clause, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. If, notwithstanding the provisions of this Section 1.2(e), a court of competent jurisdiction shall determine by a final, non-appealable order that a Lender has received interest hereunder in excess of the Maximum Lawful Rate, Administrative Agent shall, to the extent permitted by applicable law, promptly apply such excess as specified in Section 1.5(g) and thereafter shall refund any excess to Great Lakes or as such court of competent jurisdiction may otherwise order.

1.3 Yield Enhancement; Fees.

(a) Yield Enhancement. On or prior to the Closing Date, Great Lakes shall pay to Administrative Agent, for the ratable benefit of each Lender, a yield enhancement in an amount equal to 3.0% of the entire Commitment on the Closing Date.

(b) Unused Line Fee. As additional compensation for the Revolving Lenders, Great Lakes shall pay to Administrative Agent, for the ratable benefit of such Revolving Lenders, in arrears, on the last Business Day of each month prior to the Maturity Date and on the Maturity Date, a fee for Great Lakes’ non use of available funds (the “Unused Line Fee”) in an amount equal to 1.00% per annum multiplied by the difference between (x) the Maximum Amount (as it may be reduced from time to time) and (y) the average daily balance of Revolving Loans outstanding during the preceding calendar month (or portion thereof during which this Agreement is in effect).

(c) Prepayment Fee. If Great Lakes pays or prepays all or any portion of the Term Loan, whether voluntarily or involuntarily and whether before or after acceleration of the Obligations, Great Lakes shall pay to Administrative Agent, for the benefit of Lenders as liquidated damages and compensation for the costs of being prepared to make funds available hereunder a fee (the “Prepayment Fee”) in an amount equal to the Applicable Percentage (as defined below) multiplied by the sum of the principal amount of the Term Loan paid. As used herein, the term “Applicable Percentage” shall mean (i) 4.00% per annum, in the case of a prepayment on or prior to the first anniversary of the Closing Date, (ii) 3.00% per annum, in the case of a prepayment after the first anniversary of the Closing Date but on or prior to the second anniversary of the Closing Date, (iii) 2.00% per annum, in the case of a prepayment after the second anniversary of the Closing Date but prior to the third anniversary of the Closing Date and (iv) 0.00% per annum, in the case of a prepayment at anytime thereafter. Great Lakes agrees that the Applicable Percentages are a reasonable calculation of Lenders’ lost profits in view of the difficulties and impracticality of determining actual damages resulting from prepayments of the Term Loan. Notwithstanding the foregoing, no Prepayment Fee shall be payable by Great Lakes upon a mandatory prepayment of Term Loan made pursuant to Section 1.5(b).

(d) Expenses and Attorneys’ Fees. Great Lakes agrees to promptly pay all reasonable fees, charges, costs and expenses (including reasonable attorneys’ fees and expenses for one counsel (absent a conflict of interest) for the Agents collectively) incurred by each Agent in connection with any matters contemplated by or arising out of the Loan Documents, in connection with the examination, review, due diligence investigation, documentation, negotiation, closing and syndication of the transactions contemplated herein and in connection with the continued administration of the Loan Documents including any amendments, modifications, consents and

waivers (whether or not consummated). Great Lakes agrees to promptly pay reasonable documentation charges assessed by Agents for amendments, waivers, consents and any of the documentation prepared Agents’ internal legal staff (whether or not consummated). Great Lakes agrees to promptly pay all reasonable fees, charges, costs and expenses (including fees, charges, costs and expenses of attorneys, auditors (whether internal or external), appraisers, investment bankers, consultants and advisors and the allocated cost of internal legal staff) incurred by Agents in connection with any amendment, waiver, consent with respect to the Loan Documents (whether or not consummated), Event of Default, work-out or action to enforce any Loan Document or to collect any payments due from Great Lakes. In addition, in connection with any work-out or action to enforce any Loan Document or to collect any payments due from Great Lakes, Great Lakes agrees to promptly pay all reasonable fees, charges, costs and expenses incurred by Lenders for one legal counsel acting for all Lenders other than Agents and appropriate local counsel and regulatory counsel. All fees, charges, costs and expenses for which Great Lakes is responsible under this Section 1.3(d) shall be deemed part of the Obligations when incurred, payable in accordance with Section 1.4 and secured by the Collateral.

1.4 Payments.

(a) Payments by Great Lakes. All payments by Great Lakes of the Obligations shall be without deduction, defense, setoff or counterclaim and shall be made in same day funds and delivered to Administrative Agent for the benefit of Administrative Agent and Lenders, as applicable, by wire transfer to the applicable account set forth below for Administrative Agent or such other place as Administrative Agent may from time to time designate in writing.

Great Lakes shall receive credit on the first Business Day following the day of receipt for funds received by Administrative Agent by 10:00 a.m. (Mountain time). In the absence of timely receipt, such funds shall be deemed to have been paid on the next Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the payment may be made on the next succeeding Business Day and such extension of time shall be included in the computation of the amount of interest and Fees due hereunder.

(b) Apportionment and Application.

(i) So long as no Event of Default has occurred and is continuing, all principal and interest payments received by Administrative Agent or Collateral Agent (together with the proceeds of Collateral received by the Administrative Agent or Collateral Agent) shall be apportioned ratably among the Lenders (according to the unpaid principal balance of the Obligations to which such

payments relate held by each Lender) and all payments of fees and expenses received by Administrative Agent or Collateral Agent (other than fees or expenses that are for Administrative Agent’s or Collateral Agent’s separate account) shall be apportioned ratably among the Lenders having a Pro Rata Share of the type of Commitment or Obligation to which a particular fee or expense relates.

(ii) At any time that an Event of Default has occurred and is continuing, all payments remitted to Administrative Agent and all proceeds of Collateral received by Administrative Agent or Collateral Agent shall be applied as follows:

(A)

first, to pay any expenses (including cost or expense reimbursements) or indemnities then due to each Agent under the Loan Documents until paid in full,

(B)

second, to pay any fees or premiums then due to each Agent under the Loan Documents until paid in full,

(C)

third, ratably, to pay any expenses (including cost or expense reimbursements) or indemnities then due to any of the Lenders under the Loan Documents until paid in full,

(D)

fourth, ratably, to pay any fees or premiums then due to any of the Lenders under the Loan Documents until paid in full,

(E)

fifth, ratably, to pay interest accrued in respect of the Revolving Loans and the Term Loan until paid in full,

(F)

sixth, ratably to pay the principal of all Revolving Loans and Term Loan until paid in full, and

(G)

seventh, to Great Lakes (to be wired to the Designated Account) or such other Person entitled thereto under applicable law;

(c) Administrative Agent and Collateral Agent promptly shall each distribute to each Lender, pursuant to the applicable wire instructions received from each Lender in writing, such funds as it may be entitled to receive, subject to a Settlement delay as provided in Section 1.1(e).

(d) In each instance, so long as no Event of Default has occurred and is continuing, Section 1.4(b)(i) shall not apply to any payment made by Great Lakes to Administrative Agent and specified by Great Lakes to be for the payment of specific Obligations then due and payable (or prepayable) under any provision of this Agreement or any other Loan Document.

(e) For purposes of this Agreement, “paid in full” of a type of Obligation (or all Obligations) means (i) the indefeasible payment in cash or immediately available funds of all amounts owing on account of such type of Obligation (or all Obligations) (other than contingent indemnification obligations to the extent no unsatisfied claim has been asserted), including interest accrued after the commencement of any Insolvency Proceeding, default interest, interest on interest, and expense reimbursements, irrespective of whether any of the foregoing would be or is allowed or disallowed in whole or in part in any Insolvency Proceeding and (ii) the termination of the Revolving Loan Commitment.

(f) In the event of a direct conflict between the priority provisions of this Section 1.4 and any other provision contained in this Agreement or any other Loan Document, it is the intention of the parties hereto that such provisions be read together and construed, to the fullest extent possible, to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot be resolved as aforesaid, then the terms and provisions of this Section 1.4 shall control and govern.

1.5 Prepayments.

(a) Voluntary Prepayments.

(i) Voluntary Prepayments of Revolving Loans. Great Lakes may prepay the principal amount of any Revolving Loan at any time in whole or in part, without premium or penalty.

(ii) Prepayments of Term Loan. Great Lakes may, upon at least five (5) Business Days prior written notice to each Agent, prepay the principal amount of the Term Loan, in whole or in part, in minimum increments of $500,000 and integrals of $100,000 in excess thereof, or, if less, the entire principal balance of the Term Loan. Each prepayment made pursuant to this Section 1.5(a)(ii) shall be accompanied by the payment of accrued interest to the date of such payment (together with the Prepayment Fee, if applicable) on the amount prepaid. Any prepayments of the Term Loan may not be reborrowed.

(b) Prepayments from Excess Cash Flow. Within 45 days after September 30 of each year, commencing with September 30, 2012, Great Lakes shall prepay the Loans in an amount equal to fifty percent (50.0%) of the Excess Cash Flow for the applicable Excess Cash Flow Period. The calculation shall be based on the Financial Statements (and any related reports from management of Great Lakes) for Great Lakes and its Subsidiaries for such Excess Cash Flow Period. Prepayments of the Loans under this Section 1.5(b) shall be applied in accordance with Section 1.5(g).

(c) Prepayments from Extraordinary Receipts. Within one (1) Business Day of the date of receipt by Great Lakes or any of its Subsidiaries of any Extraordinary Receipts in excess of $250,000, Great Lakes shall prepay the Loans in an amount equal to 100% of such Extraordinary Receipts, net of any reasonable expenses incurred in collecting such Extraordinary Receipts which are paid to Persons who are not Affiliates of Great Lakes. All prepayments made pursuant to this Section 1.5(c) shall be applied in accordance with Section 1.5(g).

(d) Prepayments from Asset Dispositions; Casualty Events. Within one (1) Business Day of the date of receipt of any Net Proceeds from an Asset Disposition (except the Asset Dispositions permitted in Section 3.7) or from a Casualty Event, in each case, in excess of an aggregate amount of $250,000 (the “Threshold Amount”) for any Fiscal Year, Great Lakes shall prepay the Loans in an amount equal to such Net Proceeds, except, so long as no Event of Default has occurred and is continuing, that Great Lakes may reinvest all such Net Proceeds of any such

Asset Disposition or such Casualty Event within one hundred eighty (180) days, in the replacement of the assets which were the subject to any such Asset Disposition or Casualty Event with like-kind assets. Pending such reinvestment, the Net Proceeds shall either (i) be delivered to the Administrative Agent, for distribution to the Lenders, as a prepayment of the Loans or (ii) be retained by Great Lakes and deposited in a deposit account of Great Lakes in which Collateral Agent has a perfected first-priority security interest, and such Net Proceeds shall remain on deposit therein until such reinvestment occurs in accordance with the terms set forth above or such Net Proceeds are otherwise applied to the Obligations as a prepayment thereof. If Great Lakes does not intend to so reinvest such Net Proceeds or if the period set forth in the immediately preceding sentence expires without Great Lakes having reinvested the full amount of the Net Proceeds of any such Asset Disposition or such Casualty Event, then Great Lakes shall apply all such remaining Net Proceeds of such Asset Disposition or Casualty Event in excess of the Threshold Amount to payment of the Loans in accordance with Section 1.5(g). Notwithstanding the foregoing, fifty percent (50%) of any Net Proceeds with respect to an Asset Disposition or Casualty Event involving an Aircraft that are in excess of the Aircraft NOLV of such Aircraft shall be excluded from the requirements of this Section 1.5(d) and may be retained by Great Lakes for use in the ordinary course of its business, and the remaining fifty percent (50%) shall be applied to the payment of the Loans in accordance with Section 1.5(g).

(e) Incurrence of Indebtedness. Immediately upon the receipt by Great Lakes or any of its Subsidiaries of the proceeds of any incurrence of any Indebtedness (other than Indebtedness permitted pursuant to Section 3.1), Great Lakes shall prepay the Loans in an amount equal to 100% of the cash proceeds of such incurrence, net of underwriting discounts and commissions and other reasonable costs associated therewith that are paid to Persons who are not Affiliates of Great Lakes. The payments made under this Section 1.5(e) shall be applied in accordance with Section 1.5(g).

(f) Borrowing Base. If, at any time, (A) the amount of all outstanding Revolving Loans on such date exceeds (B) the Borrowing Base (such excess being referred to as the “Borrowing Base Excess Amount”), then Great Lakes shall promptly (and in any event, within two (2) Business Days) prepay the Revolving Loans (for the Pro Rata Share of each Revolving Lender) in an aggregate amount equal to the Borrowing Base Excess Amount.

(g) Application of Proceeds. With respect to any prepayments made by Great Lakes pursuant to Section 1.5(b), 1.5(c), 1.5(d), and 1.5(e) and so long as no Event of Default shall have occurred and be continuing, such prepayments shall be applied as follows: (A) first, in payment of the outstanding principal amount of the Term Loan, but not to the reduction of any amortization payments, unless all outstanding amounts of the Term Loan, other than with respect to amortization payments, have been paid in full, then in such event, such prepayments shall be applied to reduce the outstanding principal amount of the Term Loan in inverse order of maturity, and second to the Revolving Loans outstanding until the same has been repaid in full but not as a permanent reduction of the Revolving Loan Commitment, and (B) if an Event of Default shall have occurred and be continuing, be applied in the manner set forth in Section 1.4(b)(ii).

1.6 Maturity. All of the Obligations shall become due and payable as otherwise set forth herein, but in any event all of the remaining Obligations shall become due and payable upon the Maturity Date (or sooner upon the acceleration of the Loans as provided for in this Agreement).

Until all Obligations have been fully paid and satisfied (other than contingent indemnification obligations to the extent no unsatisfied claim has been asserted) and the Revolving Loan Commitment has been terminated, Collateral Agent shall be entitled to retain the security interests in the Collateral granted under the Collateral Documents on behalf of the Lenders, and each Agent and Lenders shall be entitled to retain the ability to exercise all rights and remedies available to them respectively under the Loan Documents and applicable laws. Notwithstanding anything contained in this Agreement to the contrary, upon any termination of the Revolving Loan Commitment, all of the Obligations shall be due and payable.

1.7 Register. Administrative Agent shall maintain a register (the “Register”) on its books to record the Loans, all payments made by Great Lakes with respect to the Loans, and all other debits and credits as provided in this Agreement with respect to the Loans and any other Obligations. Without limiting the foregoing, Administrative Agent may, from time to time, at Administrative Agent’s Permitted Discretion, charge the Register for any amounts due and owing by Great Lakes under the Loan Documents whereupon the same shall be deemed added to the balance of Obligations owing by Great Lakes. All entries in the Register shall be made in accordance with the customary accounting practices of Administrative Agent as in effect from time to time. The balance in the Register, as recorded on the most recent printout or other written statement of Administrative Agent shall, absent manifest error, be presumptive evidence of the amounts due and owing to Administrative Agent, Collateral Agent and Lenders by Great Lakes; provided that any failure to so record or any error in so recording shall not limit or otherwise affect Great Lakes’ duty to pay the Obligations. Any Lender may elect (which election may be revoked) to dispense with the issuance of Notes to that Lender and may rely on the Register as evidence of the amount of Obligations from time to time owing to it. Subject to Section 8.1, the Obligations and the Notes evidencing such Obligations may be assigned or otherwise transferred in whole or in part only by registration of such assignment or transfer in the Register. Any assignment or transfer of the Obligations or the Notes evidencing such Obligations shall be registered in the Register only upon delivery to each Agent of a duly executed Assignment Agreement in accordance with Section 8.1. This Section 1.7 shall be construed so that the Loans are at all times maintained in “registered form” within the meaning of Section 163(f), 871(h)(2) and 881(c)(2) of the IRC.

1.8 Reserved.

1.9 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of Great Lakes under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the Permitted Discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by Great Lakes shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b) Payment of Other Taxes by Great Lakes. Great Lakes and its Subsidiaries shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of either Agent timely reimburse such Agent for the payment of, any Other Taxes.

(c) Indemnification by Great Lakes. Great Lakes shall indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Great Lakes by a Lender (with a copy to each Agent), or by either Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) Indemnification by the Lenders. Each Lender shall severally indemnify each Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that Great Lakes has not already indemnified the Agents for such Indemnified Taxes and without limiting the obligation of Great Lakes to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 8.1(b) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent or the Collateral Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent or Collateral Agent shall be conclusive absent manifest error. Each Lender hereby authorizes each Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the either Agent to the Lender from any other source against any amount due to either Agent under this clause (d).

(e) Evidence of Payments. As soon as practicable after any payment of Taxes by Great Lakes or any of its Subsidiaries to a Governmental Authority pursuant to this Section 1.9, Great Lakes shall deliver to each Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to each Agent.

(f) Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to Great Lakes and each Agent, at the time or times reasonably requested by Great Lakes or either Agent, such properly completed and executed documentation reasonably requested by Great Lakes or either Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Great Lakes or either Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by Great Lakes or either Agent as will enable Great Lakes or the Agents to determine

whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 1.9(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s Permitted Discretion such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing,

(A) any Lender that is a U.S. Person shall deliver to Great Lakes and each Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Great Lakes or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Great Lakes and each Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Great Lakes or the Administrative Agent), whichever of the following is applicable:

(i) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii) executed originals of IRS Form W-8ECI;

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the IRC, (x) a certificate to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the IRC, a “10 percent shareholder” of Great Lakes within the meaning of Section 881(c)(3)(B) of the IRC, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the IRC (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or

(iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate on behalf of each such direct and indirect partner; and

(C) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the IRC, as applicable), such Lender shall deliver to Great Lakes and each Agent at the time or times prescribed by law and at such time or times reasonably requested by Great Lakes or either Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the IRC) and such additional documentation reasonably requested by Great Lakes or either Agent as may be necessary for Great Lakes and such Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (C), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Great Lakes and each Agent in writing of its legal inability to do so.

(g) Treatment of Certain Refunds. If any party determines, in its Permitted Discretion, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 1.9 (including by the payment of additional amounts pursuant to this Section 1.9), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this clause (g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this clause (g), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (g) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This clause shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(h) Survival. Each party’s obligations under this Section 1.9 shall survive the resignation or replacement of either Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Revolving Loan Commitment and the repayment, satisfaction or discharge of all obligations under any Loan Document.

SECTION 2.

AFFIRMATIVE COVENANTS

Great Lakes agrees as to itself and on behalf of its Subsidiaries that from and after the date hereof and until the Obligations are paid in full (other than indemnification Obligations as to which no claim has been asserted):

2.1 Compliance With Laws and Contractual Obligations. Great Lakes will (a) comply with and shall cause each of its Subsidiaries to comply with (i) the requirements of all applicable material laws, rules, regulations and orders of any Governmental Authority (including, without limitation, laws, rules, regulations and orders relating to taxes, employer and employee contributions, securities, employee retirement and welfare benefits, environmental protection matters and employee health and safety) as now in effect and which may be imposed in the future in all jurisdictions in which Great Lakes or any of its Subsidiaries is now doing business or may hereafter be doing business and (ii) the obligations, covenants and conditions contained in all Contractual Obligations of Great Lakes or any of its Subsidiaries other than those laws, rules, regulations and orders and those provisions of such Contractual Obligations the noncompliance with which could not be reasonably expected to have, either individually or in the aggregate, a Material Adverse Effect, and (b) maintain or obtain and shall cause each of its Subsidiaries to maintain or obtain all licenses, qualifications and permits now held or hereafter required to be held by Great Lakes or any of its Subsidiaries, for which the loss, suspension, revocation or failure to obtain or renew, could reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect. This Section 2.1 shall not preclude Great Lakes or its Subsidiaries from contesting any taxes or other payments, if they are being diligently contested in good faith in a manner which stays enforcement thereof and if appropriate expense provisions have been recorded in conformity with GAAP, subject to Section 3.2 and no Lien (other than a Permitted Encumbrance) in respect thereof has been created.

2.2 Insurance. Great Lakes and each of its Subsidiaries will maintain or cause to be maintained, with financially sound and reputable insurers, public liability and property damage insurance with respect to its business and properties and the business and properties of its Subsidiaries against loss or damage of the kinds customarily carried or maintained by corporations of established reputation engaged in similar businesses and in amounts acceptable to each Agent and will deliver evidence thereof to Collateral Agent. Great Lakes shall, pursuant to endorsements and/or assignments in form and substance reasonably satisfactory to each Agent, (i) cause Collateral Agent on behalf of each Lender to be named as lender’s loss payee in the case of casualty insurance and (ii) cause Collateral Agent on behalf of each Lender to be named as additional insureds in the case of all liability insurance. Great Lakes represents and warrants that it and each of its Subsidiaries currently maintains all material properties as set forth above and maintains all insurance described above. In the event Great Lakes fails to provide each Agent with evidence of the insurance coverage required by this Agreement, Collateral Agent may purchase insurance at Great Lakes’ expense to protect Collateral Agent’s interests in the Collateral. This insurance may, but need not, protect Great Lakes’ interests. The coverage purchased by Collateral Agent may not pay any claim made by Great Lakes or any claim that is made against Great Lakes in connection with the Collateral. Great Lakes may later cancel any insurance purchased by Collateral Agent, but only after providing Collateral Agent with

evidence that Great Lakes has obtained insurance as required by this Agreement. If Collateral Agent purchases insurance for the Collateral, Great Lakes will be responsible for the costs of that insurance, including interest and other Charges imposed by Collateral Agent in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance may be added by the Collateral Agent to the Obligations. The costs of the insurance may be more than the cost of insurance Great Lakes is able to obtain on its own.

2.3 Inspection; Appraisal; Lender Meeting. Great Lakes shall and shall cause its Subsidiaries to permit any authorized representatives of each Agent to visit, audit, inspect and appraise any of the properties and assets of Great Lakes and its Subsidiaries, including its and their financial and accounting records, Aircraft and Spare Engines, and to make copies and take extracts therefrom, and to discuss its and their affairs, finances and business with its and their officers and certified public accountants, at such reasonable times during normal business hours and as often as may be reasonably requested. Great Lakes shall pay all normal audit, appraisal and field examination fees and reasonable out-of-pocket expenses of each Agent related to any such visit, audit and/or field examination (“Examination Costs”) and to any such appraisal (“Appraisal Costs”); provided that so long as no Event of Default shall have occurred and remain continuing, Great Lakes shall not be obligated to pay Examination Costs for more than two (2) field examinations by Agents (and their designees) each calendar year and Appraisal Costs for more than two (2) desk-top appraisals on Inventory and one (1) full appraisal on all assets, in each case by Agents (and their designees) each calendar year. Without in any way limiting the foregoing, Great Lakes will participate and will cause key management personnel of Great Lakes and its Subsidiaries to participate in an in-person meeting with each Agent and Lenders at least once during each year, which in-person meeting shall be held at such time and such place as may be reasonably requested by each Agent. Without limiting the foregoing, Great Lakes and its Subsidiaries, as applicable, will store original Aircraft log books in a fire rated container and will maintain electronic maintenance records in accordance with applicable FAA requirements.

2.4	Maintenance of Existence and Conduct of Business. Great Lakes shall:

(a) do or cause to be done all things necessary to preserve and keep in full force and effect its existence and its rights, permits, licenses, privileges and franchises material to its business;

(b) continue to conduct its business substantially as now conducted or as otherwise permitted hereunder;

(c) at all times maintain, preserve and protect all of its assets and properties used or useful in the conduct of its business, and keep the same in good repair, working order and condition in all material respects (taking into consideration ordinary wear and tear) and from time to time make, or cause to be made, all necessary or appropriate repairs, replacements and improvements thereto consistent with industry practices; and

(d) transact business only in such corporate and trade names as are set forth in Schedule 2.4.

2.5 Environmental Matters. Great Lakes shall and shall cause each Person within its control to promptly forward to each Agent a copy of any order, notice, request for information or any communication or report received by Great Lakes or any Person within its control in connection with any such violation or Release or any other matter relating to any Environmental Laws or Environmental Permits that could reasonably be expected to result in Environmental Liabilities in excess of $250,000, in each case whether or not the Environmental Protection Agency or any Governmental Authority has taken or threatened any action in connection with any such violation, Release or other matter.

2.6 Landlords’ Agreements, Mortgagee Agreements, Bailee Letters and Real Estate Purchases. With respect to the corporate headquarters and in each Agent’s Permitted Discretion, any other material locations of Great Lakes and its Subsidiaries where Collateral in the aggregate in excess of $100,000 is or may be located, Great Lakes shall and shall cause its Subsidiaries and, with respect to all other locations, Great Lakes shall and shall cause its Subsidiaries to use best efforts to, obtain a Collateral Access Agreement or Mortgagee Agreements, as applicable, from the lessor of any Real Estate leased by Great Lakes, the mortgagee of any Real Estate owned by Great Lakes or the bailee with respect to any warehouse, processor or converter facility or other location where Collateral is stored or located, as applicable, which Collateral Access Agreement or Mortgagee Agreement, as applicable, shall contain a waiver or subordination of all Liens or claims that the landlord, bailee or mortgagee may assert against the Collateral at that location, shall permit each Agent access to the related premises and shall otherwise be reasonably satisfactory in form and substance to each Agent. Great Lakes shall and shall cause its Subsidiaries to timely and fully pay and perform their obligations under all leases and other agreements with respect to each leased location or public warehouse where any Collateral is or may be located.

2.7	Further Assurances.

(a) Great Lakes shall, from time to time, execute such financing statements, documents, security agreements and reports as Administrative Agent, Collateral Agent or Requisite Lenders at any time may reasonably request to evidence, perfect or otherwise implement the guaranties and security for repayment of the Obligations contemplated by the Loan Documents.

(b) In the event Great Lakes or any of its Subsidiaries acquires a fee ownership interest in real property with a fair market value in excess of $250,000 after the Closing Date, Great Lakes or such Subsidiary shall deliver to each Agent a fully executed mortgage or deed of trust over such real property in form and substance satisfactory to each Agent, together with such title insurance policies, surveys, appraisals, evidence of insurance, legal opinions, environmental assessments and other documents and certificates as shall be required by either Agent.

(c) Great Lakes shall (i) cause each Person, upon its becoming a Subsidiary of Great Lakes (provided that this shall not be construed to constitute consent by any of the Lenders to any transaction not expressly permitted by the terms of this Agreement), promptly to guaranty the Obligations and to grant to Collateral Agent, for the benefit the Lenders, a security interest in the real, personal and mixed property of such Person to secure the Obligations and (ii) pledge, or cause to be pledged, to Collateral Agent, for the benefit of the Lenders, all of the Stock of such

Subsidiary to secure the Obligations; provided that only 65% of the total outstanding voting Stock of any first tier Subsidiary of Great Lakes that is a CFC (and none of the Stock of any Subsidiary of such CFC) shall be required to be pledged if pledging a greater amount would result in adverse tax consequences or the costs to Great Lakes of providing such pledge or perfecting the security interests created thereby are unreasonably excessive (as determined by Administrative Agent and Collateral Agent in consultation with Great Lakes) in relation to the benefits of Collateral Agent and the Lenders of the security or guarantee afforded thereby (which pledge, if reasonably requested by either Agent, shall be governed by the laws of the jurisdiction of such Subsidiary). The documentation for such guaranty, security and pledge shall be substantially similar to the Loan Documents executed concurrently herewith with such modifications as are reasonably requested by the Agents.

(d) Without limiting the generality of the foregoing, if ownership of any Aircraft or Spare Engine is acquired by Great Lakes or any of its Subsidiaries after the Closing Date, Great Lakes or such Subsidiary will, as soon as reasonably practical after such acquisition, deliver to the Collateral Agent each of the following, in form and substance satisfactory to each of the Agents in their Permitted Discretion, all at the expense of Great Lakes:

(i) an Aircraft Security Agreement, satisfactory to each Agent;

(ii) evidence that a counterpart of such Aircraft Security Agreement has been recorded in all places necessary, in the Agents’ judgment, to create a valid and enforceable Lien in favor of the Collateral Agent for the benefit of the Lenders, prior and superior in right to any other Person; and

(iii) such other information, documentation and certifications as may be required by the Agents.

For the avoidance of doubt, and in addition to the foregoing, Great Lakes and its Subsidiaries will cooperate with the Agents and execute such further instruments and documents as the Agents may request prior to any Aircraft owned by Great Lakes or any of its Subsidiaries being located in any foreign jurisdiction that has not adopted and ratified the Cape Town Convention to create, maintain and/or evidence a valid and enforceable Lien in favor of the Collateral Agent, for the benefit of the Lenders, prior and superior in right to any other Person in such jurisdiction; provided that the foregoing shall not be deemed to be the Agents’ consent to such Aircraft being located outside of the United States.

2.8	Cash Management Systems.

(a) Great Lakes shall enter into a Control Agreement with respect to Great Lakes’ primary deposit accounts maintained by Great Lakes with Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. (other than any payroll account and any payroll tax and/or similar trust fund accounts) as of or after the Closing Date. Such Control Agreement shall be in form and substance satisfactory to each Agent and permit Collateral Agent to assume exclusive dominion and control of such deposit account; provided that Collateral Agent shall not exercise its exclusive dominion and control with respect to such deposit account so long as no Event of Default has occurred and remains continuing; provided further, that once an Event of Default has occurred and remains

continuing (a “Funds Control Event”), unless Collateral Agent shall otherwise elect, such Funds Control Event shall remain in effect until each Agent has determined that no Event of Default has occurred and is continuing for a period of two (2) consecutive calendar months.

(b) Any Lender may at any time sell to one or more banks or financial institutions (a “Participant”) participating interests in all or any portion of its Loan, its Commitment, and the other rights and interests of that Lender (the “Originating Lender”) hereunder and under the other Loan Documents; provided, however, that (i) the Originating Lender shall remain a “Lender” for all purposes of this Agreement and the other Loan Documents and the Participant receiving the participating interest in the Loan, the Commitments, and the other rights and interests of the Originating Lender hereunder shall not constitute a “Lender” hereunder or under the other Loan Documents and the Originating Lender’s obligations under this Agreement shall remain unchanged, (ii) the Originating Lender shall remain solely responsible for the performance of such obligations, (iii) Great Lakes, Agents, and the Lenders shall continue to deal solely and directly with the Originating Lender in connection with the Originating Lender’s rights and obligations under this Agreement and the other Loan Documents, (iv) no Lender shall transfer or grant any participating interest under which the Participant has the right to approve any amendment to, or any consent or waiver with respect to, this Agreement or any other Loan Document, except to the extent such amendment to, or consent or waiver with respect to this Agreement or of any other Loan Document would (A) extend the final maturity date of the Loan hereunder in which such Participant is participating, (B) reduce the interest rate (other than a waiver of default interest) applicable to the Loan in which such Participant is participating, (C) release all or substantially all of the Collateral or guaranties (except to the extent expressly

The rights of any Participant only shall be derivative through the Originating Lender with whom such Participant participates and no Participant shall have any rights under this Agreement or any other Loan Document or any direct rights as to the other Lenders, Agents, Great Lakes, the Collateral, or otherwise in respect of the Obligations. No Participant shall have the right to participate directly in the making of decisions by the Lenders among themselves. Each Lender that sells a participation shall, acting solely for this purpose as an agent for Great Lakes, shall maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided, that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.

(c) Any Lender, with the consent of each Agent (not to be unreasonably withheld, conditioned or delayed) and, so long as no Default or Event of Default has occurred and continuing, with the consent of Great Lakes (not to be unreasonably withheld, conditioned or delayed), may sell, assign or transfer all or any part of its rights and obligations under or relating to Loans and/or Commitments under this Agreement and the other Loan Documents to one or more Permitted Assignees (each a “Purchasing Lender”), in minimum amounts of not less than $1,000,000, pursuant to a Assignment Agreement, executed by a Purchasing Lender, the assigning Lender, and each Agent and delivered to the Administrative Agent for recording; provided, however, that such minimum amount shall not apply, and the consent of the Agents and Great Lakes shall not be required (but the Purchasing Lender shall nevertheless provide each Agent with a fully executed copy of the Assignment Agreement), if the Purchasing Lender is a Permitted Assignee pursuant to clauses (a), (c), or (d) of the definition of Permitted Assignee. Upon such execution, delivery, acceptance and recording, from and after the assignment effective date determined pursuant to such Assignment Agreement, (i) Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Assignment Agreement, have the rights and obligations of a Lender hereunder and (ii) the assigning Lender thereunder shall, to the extent provided in such Assignment Agreement, be released from its obligations under this Agreement, the Assignment Agreement creating a novation for that purpose.

rights and obligations of such assigning Revolving Lender under this Agreement and the other Loan Documents. Great Lakes hereby consents to the addition of such Purchasing Lender and the resulting adjustment of the Revolving Loan Commitments arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such assigning Lender under this Agreement and the other Loan Documents. Great Lakes shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

(g) Great Lakes shall not, and shall not permit any Subsidiary or Affiliate to purchase, redeem, prepay, tender for or otherwise acquire, directly or indirectly, any of the outstanding Loans except upon the full repurchase or prepayment of the Loans in accordance with the other terms of this Agreement. Great Lakes will promptly cancel all Loans acquired by it or any of its Subsidiaries or Affiliates pursuant to any purchase, redemption, prepayment or tender for the Loans pursuant to any provision of this Agreement or otherwise and no Loans may be issued in substitution or exchange for any such Loans.

by such Lender to such Persons and (ii) any Lender which is a fund may pledge, or grant a security interest in, all or any portion of its rights and other obligations under or relating to Loans under this Agreement and the other Loan Documents to its trustee in support of its obligation to its trustee. No pledge or grant of a security interest pursuant to this clause (h) shall release the transferor Lender from any of its obligations hereunder.

(i) Notwithstanding anything in this Agreement or the other Loan Documents to the contrary, GB Merchant and Crystal shall have a right of first offer with respect to a proposed sale or assignment by another Lender of its portion of the Loans regardless of whether before or after the occurrence of an Event of Default (other than a sale or assignment to a Permitted Assignee pursuant to clauses (a), (c) or (d) of such definition or an assignment pursuant to Section 8.1(f)(I) or 8.1(f)(II)). Within five (5) Business Days of receipt by the non-assigning Lenders of notice of a proposed sale or assignment of the assigning Lender’s portion of the Loans, the non-assigning Lenders shall have the right to purchase all, but not less than all, of the Loans on the same terms and conditions set forth in Section 8.1; provided that if more than one non-assigning Lender exercises its right to purchase such Loans, then such Lenders shall purchase the Loans on a pro rata basis.

(i) Administrative Agent. Each Lender hereby designates and appoints Crystal as its Administrative Agent under this Agreement and the other Loan Documents, and each Lender hereby irrevocably authorizes Crystal, as Administrative Agent, to take such action or to refrain from taking such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers as are set forth herein or therein, together with such other powers as are reasonably incidental thereto. In performing its functions and duties under this Agreement, Administrative Agent shall act solely as agent of the applicable Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for Great Lakes or its Subsidiaries. Administrative Agent may perform any of its duties hereunder, or under the Loan Documents, by or through its agents or employees.

(ii) Collateral Agent. Each Lender hereby designates and appoints GB Merchant as its Collateral Agent under this Agreement and the other Loan Documents, and each Lender hereby irrevocably authorizes GB Merchant, as Collateral Agent, to take such action or to refrain from taking such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers as are set forth herein or therein, together with such other powers as are reasonably incidental thereto. In performing its functions and duties under this Agreement, Collateral Agent shall act solely as agent of the applicable Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for Great Lakes or its Subsidiaries. Collateral Agent may perform any of its duties hereunder, or under the Loan Documents, by or through its agents or employees.

(iii) Agents are authorized and empowered to amend, modify, or waive any provisions of this Agreement or the other Loan Documents on behalf of Lenders subject to the requirement that certain of Lenders’ consent be obtained in certain instances as provided in this Section 8.2 and Section 9.2. The provisions of this Section 8.2 are solely for the benefit of Agents and Lenders and neither Great Lakes nor any of its Subsidiaries shall have any rights as a third-party beneficiary of any of the provisions hereof.

(b) Nature of Duties. The duties of each Agent shall be mechanical and administrative in nature. Agents shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender. Nothing in this Agreement or any of the Loan Documents, express or implied, is intended to or shall be construed to impose upon Administrative Agent or Collateral Agent any obligations in respect of this Agreement or any of the Loan Documents except as expressly set forth herein or therein. Each Lender shall make its own independent investigation of the financial condition and affairs of Great Lakes in connection with the extension of credit hereunder and shall make its own appraisal of the creditworthiness of Great Lakes and neither Administrative Agent nor Collateral Agent shall have any duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto (other than as expressly required herein). If either Agent seeks the consent or approval of any Lenders to the taking or refraining from taking any action hereunder, then such Agent shall send notice thereof to each applicable Lender. Agents shall notify each applicable Lender any time that the Requisite Lenders and/or the Requisite Revolving Lenders have instructed Agents to act or refrain from acting pursuant hereto. Notwithstanding anything contained herein to the contrary, the Collateral Agent agrees to consult with the Administrative Agent in the exercise of any rights and remedies in respect of realizing upon the Collateral.

(c) Rights, Exculpation, Etc. Neither Agent nor any of their respective officers, directors, employees or agents shall be liable to any Lender for any action taken or omitted by them hereunder or under any of the Loan Documents, or in connection herewith or therewith, except that Agents shall be liable to the extent of their own gross negligence or willful misconduct as determined by a final non-appealable order by a court of competent jurisdiction. Agents shall not be liable for any apportionment or distribution of payments made in good faith and if any such apportionment or distribution is subsequently determined to have been made in error the sole recourse of any Lender to whom payment was due but not made, shall be to recover from other Lenders any payment in excess of the amount to which they are determined to be entitled (and such other Lenders hereby agree to return to such Lender any such erroneous payments received by them). In no event shall Agents be liable for punitive, special, consequential, incidental, exemplary or other similar damages. In performing their respective functions and duties hereunder, each Agent shall exercise substantially the same care which it would in dealing with loans for its own account, but neither Agent nor any of their respective agents or representatives shall be responsible to any Lender for any recitals, statements, representations or warranties herein or for the execution, effectiveness, genuineness, validity, enforceability, collectability, or sufficiency of this Agreement or any of the Loan Documents or the transactions contemplated thereby, or for the financial condition of Great Lakes. Agents shall not be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any of the Loan Documents or the

financial condition of Great Lakes, or the existence or possible existence of any Default or Event of Default. Agents may at any time request instructions from Requisite Lenders, Requisite Revolving Lenders or all affected Lenders with respect to any actions or approvals which by the terms of this Agreement or of any of the Loan Documents, Agents are permitted or required to take or to grant. If such instructions are requested, Agents shall be absolutely entitled to refrain from taking any action or to withhold any approval and shall not be under any liability whatsoever to any Person for refraining from any action or withholding any approval under any of the Loan Documents until it shall have received such instructions from the Requisite Lenders, Requisite Revolving Lenders, or all affected Lenders, as applicable. Without limiting the foregoing, no Lender shall have any right of action whatsoever against either Agent as a result of such Agent acting or refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of Requisite Lenders, Requisite Revolving Lenders or all affected Lenders, as applicable; and, notwithstanding the instructions of Requisite Lenders, Requisite Revolving Lenders or all affected Lenders, as applicable, no Agent shall have any obligation to take any action if it believes, in good faith, that such action is deemed to be illegal by such Agent or exposes such Agent to any liability for which it has not received satisfactory indemnification in accordance with Section 8.2(e).

(d) Reliance. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any written or oral notices, statements, certificates, orders or other documents or any telephone message or other communication (including any electronic communication, writing, or fax) believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement or any of the Loan Documents and its duties hereunder or thereunder. Each Agent shall be entitled to rely upon the advice of legal counsel, independent accountants, and other experts selected by such Agent in its Permitted Discretion.

(e) Indemnification. Lenders will reimburse and indemnify each Agent for and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including, without limitation, attorneys’ fees and expenses), advances or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against Administrative Agent or Collateral Agent in its capacity as such in any way relating to or arising out of this Agreement or any of the Loan Documents or any action taken or omitted by the Administrative Agent or the Collateral Agent in its capacity as such in under this Agreement or any of the Loan Documents, in proportion to each Lender’s Pro Rata Share; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances or disbursements to the extent resulting from an Agent’s gross negligence or willful misconduct as determined by a final non-appealable order by a court of competent jurisdiction. If any indemnity furnished to an Agent for any purpose shall, in the opinion of such Agent, be insufficient or become impaired, such Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against even if so directed by the Requisite Lenders, the Requisite Revolving Lenders or such other portion of the Lenders as shall be prescribed by this Agreement until such additional indemnity is furnished. The obligations of Lenders under this Section 8.2(e) shall survive the payment in full of the Obligations and the termination of this Agreement.

(f) Crystal (or any successor Administrative Agent); GB Merchant (or any successor Collateral Agent).

(i) With respect to its Commitments and Loans hereunder, Crystal (or any successor Administrative Agent) shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender. The terms “Lenders”, “Requisite Lenders”, “Requisite Revolving Lenders”, or any similar terms shall, unless the context clearly otherwise indicates, include Crystal (or any successor Administrative Agent) in its individual capacity as a Lender, one of the Requisite Lenders or one of the Requisite Revolving Lenders. Crystal (or any successor Administrative Agent), either directly or through strategic affiliations, may lend money to, acquire equity or other ownership interests in, provide advisory services to and generally engage in any kind of banking, trust or other business with Great Lakes or any of its Subsidiaries as if it were not acting as Administrative Agent pursuant hereto and without any duty to account therefor to Lenders. Crystal (or any successor Administrative Agent), either directly or through strategic affiliations, may accept fees and other consideration from Great Lakes or any of its Subsidiaries for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

(ii) With respect to its Commitments and Loans hereunder, GB Merchant (or any successor Collateral Agent) shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender. The terms “Lenders”, “Requisite Lenders”, “Requisite Revolving Lenders”, or any similar terms shall, unless the context clearly otherwise indicates, include GB Merchant (or any successor Collateral Agent) in its individual capacity as a Lender, one of the Requisite Lenders or one of the Requisite Revolving Lenders. GB Merchant (or any successor Collateral Agent), either directly or through strategic affiliations, may lend money to, acquire equity or other ownership interests in, provide advisory services to and generally engage in any kind of banking, trust or other business with Great Lakes or any of its Subsidiaries as if it were not acting as Collateral Agent pursuant hereto and without any duty to account therefor to Lenders. GB Merchant (or any successor Collateral Agent), either directly or through strategic affiliations, may accept fees and other consideration from Great Lakes or any of its Subsidiaries for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

(A)

Resignation. Administrative Agent may resign from the performance of all its agency functions and duties hereunder at any time by giving at least thirty (30) days’ prior written notice to Collateral Agent, Great Lakes and Lenders.

If a successor Administrative Agent shall not have been so appointed within the thirty (30) day period referred to in clause (i) above, the retiring Administrative Agent upon notice to Collateral Agent, and Great Lakes, shall then appoint a successor Administrative Agent who shall serve as Administrative Agent until such time, if any, as Requisite Lenders appoint a successor Administrative Agent in the manner as provided above; provided that if the Administrative Agent has not appointed (or chooses not to appoint) a successor Administrative Agent then the Requisite Lenders shall serve as the successor Administrative Agent until such time when the Requisite Lenders appoint a successor Administrative Agent.

After any retiring Administrative Agent’s resignation as Administrative Agent the provisions of this Section 8.2 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it in its capacity as Administrative Agent.

(B)

Appointment of Successor. Upon any such applicable notice of resignation pursuant to clause (i) above, the Administrative Agent shall have the right, in Administrative Agent’s Permitted Discretion, to assume the role of Collateral Agent, and if the Administrative Agent declines to assume such role as Collateral Agent, the Requisite Lenders shall appoint a successor Collateral Agent, which shall be reasonably acceptable to the Administrative Agent, and, unless an Event of Default has occurred and is continuing, shall be reasonably acceptable to Great Lakes.

After any retiring Collateral Agent’s resignation as Collateral Agent the provisions of this Section 8.2 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it in its capacity as Collateral Agent.

(h) Collateral Matters.

(i) Release of Collateral. Lenders hereby irrevocably authorize Collateral Agent, at its option and in its Permitted Discretion, to release any Lien granted to or held by Collateral Agent upon any Collateral (x) upon termination of the Revolving Loan Commitments and payment and satisfaction of all Obligations (other than contingent indemnification obligations to the extent no claims giving rise thereto have been asserted), (y) constituting property being sold or disposed of if Great Lakes (or any of them) certify to each Agent that the sale or disposition is made in compliance with the provisions of this Agreement (and each Agent may rely in good faith conclusively on any such certificate, without further inquiry) or (z) in accordance with the provisions of the next sentence. In addition, with the consent of Requisite Lenders and the Administrative Agent, Collateral Agent may release any Lien granted to or held by Collateral Agent upon any

Collateral having a book value not greater than ten percent (10%) of the total book value of all Collateral, either in a single transaction or in a series of related transactions.

(ii) Confirmation of Authority; Execution of Releases. Without in any manner limiting Collateral Agent’s authority to act without any specific or further authorization or consent by Lenders (as set forth in Section 8.2(h)(i)), each Lender agrees to confirm in writing, upon request by each Agent or Great Lakes, the authority to release any Collateral conferred upon Collateral Agent under clauses (x) and (y) of Section 8.2(h)(i). Upon receipt by Collateral Agent of any required confirmation from the Administrative Agent and Requisite Lenders of its authority to release any particular item or types of Collateral, and upon at least ten (10) Business Days’ prior written request by Great Lakes, Collateral Agent shall (and is hereby irrevocably authorized by Lenders to) execute such documents as may be necessary to evidence the release of the Liens granted to Collateral Agent upon such Collateral; provided, however, that (x) Collateral Agent shall not be required to execute any such document on terms which, in Collateral Agent’s opinion, would expose Collateral Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (y) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or obligations of Great Lakes or any of its Subsidiaries, in respect of), all interests retained by Great Lakes or any of its Subsidiaries, including the proceeds of any sale, all of which shall continue to constitute part of the Collateral.

(iii) Absence of Duty. Collateral Agent shall have no obligation whatsoever to any Lender or any other Person to assure that the property covered by the Collateral Documents exists or is owned by Great Lakes or any of its Subsidiaries or is cared for, protected or insured or has been encumbered or that the Liens granted to Collateral Agent have been properly or sufficiently or lawfully created, perfected, protected or enforced or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to Collateral Agent in this Section 8.2(h) or in any of the Loan Documents, it being understood and agreed that in respect of the property covered by the Collateral Documents or any act, omission or event related thereto, Collateral Agent may act in any manner it may deem appropriate, in its Permitted Discretion, given Collateral Agent’s own interest in property covered by the Collateral Documents as one of the Lenders and that Collateral Agent shall have no duty or liability whatsoever to any of the other Lenders, provided that Collateral Agent shall exercise the same care which it would in dealing with loans for its own account.

(i) Agency for Perfection. Collateral Agent, Administrative Agent and each Lender hereby appoint each other Lender as agent for the purpose of perfecting Collateral Agent’s security interest in assets which, in accordance with the Code in any applicable jurisdiction, can be perfected by possession or control. Should any Lender (other than Collateral Agent) obtain

possession or control of any such assets, such Lender shall notify Collateral Agent thereof, and, promptly upon Collateral Agent’s request therefor, shall deliver such assets to Collateral Agent or in accordance with Collateral Agent’s instructions or transfer control to Collateral Agent in accordance with Collateral Agent’s instructions. Each Lender agrees that it will not have any right individually to enforce or seek to enforce any Collateral Document or to realize upon any collateral security for the Loans unless instructed to do so by Collateral Agent in writing, it being understood and agreed that such rights and remedies may be exercised only by Collateral Agent.

(j) Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default except with respect to defaults in the payment of principal, interest and Fees required to be paid to Administrative Agent for the account of Lenders, unless Agents shall have received written notice from a Lender or Great Lakes referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. Each Agent will use reasonable efforts to notify each Lender of its receipt of any such notice. Agents shall take such action with respect to such Default or Event of Default as may be requested by Requisite Lenders in accordance with Section 7. Unless and until Agents have received any such request, Agents may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interests of Lenders.

(k) Lender Actions Against Collateral. Each Lender agrees that it will not take any enforcement action, nor institute any actions or proceedings, with respect to the Loans, against Great Lakes or any of its Subsidiaries or under the other Loan Documents or against any Collateral (including the exercise of any right of set-off without the consent of each Agent and Requisite Lenders.) All such enforcement actions and proceedings shall be taken in concert and at the direction with the consent of each Agent or Requisite Lenders. Administrative Agent is authorized to issue all notices to be issued by or on behalf of Lenders with respect to any Subordinated Debt. With respect to any action by Administrative Agent or Collateral Agent to enforce the rights and remedies of Administrative Agent, Collateral Agent and the Lenders under this Agreement and the other Loan Documents, each Lender hereby consents to the jurisdiction of the court in which such action is maintained, and agrees to deliver its Notes to each Agent to the extent necessary to enforce the rights and remedies of each Agent for the benefit of the Agents and Lenders under the Mortgages in accordance with the provisions hereof.

(l) Agent Reports. Each Lender may from time to time receive one or more reports or other information (each, a “Report”) prepared by or on behalf of an Agent (or one or more of such Agent’s Affiliates). With respect to each Report, each Lender hereby agrees that:

(i) No Agent (nor such Agent’s Affiliates) shall have any duties or obligations in connection with or as a result of a Lender receiving a copy of a Report, which will be provided solely as a courtesy, without consideration. Each Lender will perform its own diligence and will make its own independent investigation of the operations, financial conditions and affairs of Great Lakes and its Subsidiaries and will not rely on any Report or make any claim that it has done so. In addition, each Lender releases, and agrees that it will not assert, any claim against an Agent (or one or more of such Agent’s Affiliates) that in any way relates to any Report or arises out of a Lender having access to any Report or any

discussion of its contents, and each Lender agrees to defend, indemnify and hold harmless such Agent (and such Agent’s Affiliates) and their respective officers, directors, employees, agents, representatives and attorneys from all claims, liabilities and expenses relating to a breach by a Lender or any of its personnel of this Section or otherwise arising out of a Lender’s access to any Report or any discussion of its contents;

(ii) Each Report may not be complete and certain information and findings obtained by an Agent (or one or more of such Agent’s Affiliates) regarding the operations and condition of Great Lakes and its Subsidiaries may not be reflected in each Report. Agents (and Agents’ Affiliates) make no representations or warranties of any kind with respect to (i) any existing or proposed financing; (ii) the accuracy or completeness of the information contained in any Report or in any other related documentation; (iii) the scope or adequacy of Agents’ (and Agents’ Affiliates’) due diligence, or the presence or absence of any errors or omissions contained in any Report or in any other related documentation; and (iv) any work performed by or on behalf of Agents (or one or more of Agents’ Affiliates) in connection with or using any Report or any related documentation; and

(iii) Each Lender agrees to safeguard each Report and any related documentation with the same care which it uses with respect to information of its own which it does not desire to disseminate or publish, and agrees not to reproduce or distribute or provide copies of or disclose any Report or any other related documentation or any related discussions to anyone.

8.3 Set Off and Sharing of Payments. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, during the continuance of any Event of Default, each Lender is hereby authorized by Great Lakes at any time or from time to time, with reasonably prompt subsequent notice to Great Lakes (any prior or contemporaneous notice being hereby expressly waived) to set off and to appropriate and to apply any and all (A) balances held by such Lender at any of its offices for the account of Great Lakes (regardless of whether such balances are then due to Great Lakes), and (B) other property at any time held or owing by such Lender to or for the credit or for the account of Great Lakes, against and on account of any of the Obligations; except that no Lender shall exercise any such right without the prior written consent of each Agent and the Requisite Lenders. Notwithstanding anything herein to the contrary, the failure to give notice of any set off and application made by such Lender to Great Lakes shall not affect the validity of such set off and application. Any Lender exercising a right to set off shall purchase for cash (and the other Lenders shall sell) interests in each of such other Lender’s Pro Rata Share of the Obligations as would be necessary to cause all Lenders to share the amount so set off with each other Lender entitled to share in the amount so set off in accordance with their respective Pro Rata Shares. Great Lakes agrees, to the fullest extent permitted by law, that any Lender may exercise its right to set off with respect to amounts in excess of its Pro Rata Share of the Obligations and upon doing so shall deliver such amount so set off to the Administrative Agent for the benefit of all Lenders entitled to share in the amount so set off in accordance with their Pro Rata Shares.

SECTION 9.

MISCELLANEOUS

9.1 Indemnities. Great Lakes agrees, to indemnify, pay, and hold each Agent, each Lender and their respective Affiliates, officers, directors, employees, agents, and attorneys (the “Indemnitees”) harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs and expenses (including all reasonable fees and expenses of counsel to such Indemnitees) of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Indemnitee as a result of such Indemnitees being a party to this Agreement or the transactions consummated pursuant to this Agreement or otherwise relating to any of the Loan Documents; provided, that Great Lakes shall not have any obligation to an Indemnitee hereunder with respect to liabilities to the extent resulting from the gross negligence or willful misconduct of that Indemnitee as finally determined by a court of competent jurisdiction. If and to the extent that the foregoing undertaking may be unenforceable for any reason, Great Lakes agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

9.2 Amendments and Waivers.

(a) Except for actions expressly permitted to be taken by Agents, no amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, or any consent to any departure by Great Lakes therefrom, shall in any event be effective unless the same shall be in writing and signed by Great Lakes, and by Requisite Lenders, Requisite Revolving Lenders or all affected Lenders, as applicable.

Notwithstanding anything contained in this Agreement to the contrary, no waiver or consent with respect to any Default or any Event of Default shall be effective for purposes of the conditions precedent to the making of Loans set forth in Section 6.2 unless the same shall be in writing and signed by each Agent, Requisite Lenders and Great Lakes.

(c) No amendment, modification, termination or waiver shall, unless in writing and signed by each Agent and each Lender directly affected thereby: (i) increase the principal amount, or postpone or extend the scheduled date of expiration, of any Lender’s Commitment (which action shall be deemed to directly affect all Lenders); (ii) reduce the principal of, rate of interest on (other than any determination or waiver to charge or not charge interest at the Default Rate) or Fees payable with respect to any Loan of any affected Lender; (iii) extend any scheduled payment date or final maturity date of the principal amount of any Loan of any affected Lender; (iv) waive, forgive, defer, extend or postpone any payment of interest or Fees as to any affected Lender (which action shall be deemed only to affect those Lenders to whom such payments are made); (v) release all or substantially all of the Collateral, except as otherwise provided in this

Agreement or the other Loan Documents; (vi) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Loans that shall be required for Lenders or any of them to take any action hereunder (which action shall be deemed to directly affect all Lenders); and (vii) amend or waive this Section 9.2 or the definition of the terms “Requisite Lenders” or “Requisite Revolving Lenders” insofar as such definition affects the substance of this Section 9.2 or the term “Pro Rata Share” (which action shall be deemed to directly affect all Lenders). Furthermore, no amendment, modification, termination or waiver affecting the rights or duties of each Agent under this Agreement or any other Loan Document shall be effective unless in writing and signed by each Agent in addition to Lenders required hereinabove to take such action.

No amendment, modification, termination or waiver shall be required for either Agent to take additional Collateral pursuant to any Loan Document. No amendment, modification, termination or waiver of any provision of any Note shall be effective without the written concurrence of the holder of that Note. No notice to or demand on Great Lakes in any case shall entitle Great Lakes to any other or further notice or demand in similar or other circumstances. Any amendment, modification, termination, waiver or consent effected in accordance with this Section 9.2 shall be binding upon each holder of the Notes at the time outstanding and each future holder of the Notes.

9.4 Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or delay on the part of Agents or any Lender to exercise, nor any partial exercise of, any power, right or privilege hereunder or under any other Loan Documents shall impair such power, right, or privilege or be construed to be a waiver of any Default or Event of Default. All rights and remedies existing hereunder or under any other Loan Document are cumulative to and not exclusive of any rights or remedies otherwise available.

9.5 Marshaling; Payments Set Aside. Neither Agents nor any Lender shall be under any obligation to marshal any assets in payment of any or all of the Obligations. To the extent that Great Lakes makes payment(s) or Agents enforce the Liens or Agents or any Lender exercises its right of set-off, and such payment(s) or the proceeds of such enforcement or set-off is subsequently invalidated, declared to be fraudulent or preferential, set aside, or required to be repaid by anyone (whether as a result of any demand, litigation, settlement or otherwise), then to the extent of such recovery, the Obligations or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or set-off had not occurred.

9.6 Severability. The invalidity, illegality, or unenforceability in any jurisdiction of any provision under the Loan Documents shall not affect or impair the remaining provisions in the Loan Documents.

9.7 Lenders’ Obligations Several; Independent Nature of Lenders’ Rights. The obligation of each Lender hereunder is several and not joint and no Lender shall be responsible for the obligation or commitment of any other Lender hereunder. In the event that any Lender at any time should fail to make a Loan as herein provided, the Lenders, or any of them, at their sole option, may make the Loan that was to have been made by the Lender so failing to make such Loan. Nothing contained in any Loan Document and no action taken by Administrative Agent or Collateral Agent or any Lender pursuant hereto or thereto shall be deemed to constitute Lenders to be a partnership, an association, a joint venture or any other kind of entity.

(b) In the case of a Defaulting Lender, at Great Lakes’ request, each Agent or a Person acceptable to each Agent shall have the right with each Agent’s consent and in each Agent’s Permitted Discretion (but shall have no obligation) to purchase from any Defaulting Lender, and each Defaulting Lender agrees that it shall, at Administrative Agent’s or Collateral Agent’s request, sell and assign to such Agent or such Person, all of the Loans and Commitments of that Defaulting Lender for an amount equal to the principal balance of all Loans held by such Defaulting Lender and all accrued interest and Fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment Agreement.

(c) If, in connection with any proposed amendment, modification, waiver or termination pursuant to Section 9.2 (a “Proposed Change”) requiring the consent of all affected Lenders, the consent of Requisite Lenders is obtained, but the consent of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained being referred to as a “Non-Consenting Lender”); then, so long as no Agent is a Non-Consenting Lender, a Person reasonably acceptable to each Agent shall have the right with each Agent’s consent and in each Agent’s Permitted Discretion (but shall have no obligation) to purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree that they shall, upon such Agent’s request, sell and assign to such Agent or such Person, all of the Loans and Commitments of such Non-Consenting Lenders for an amount equal to the principal balance of all Loans held by the Non-Consenting Lenders and all accrued interest and Fees and other Obligations owing (including, any Prepayment Fee) with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment Agreement; it being understood that an assignment pursuant to this Section 9.19(c) shall not require the consent of Great Lakes.

Upon payment in full in cash and performance of all of the Obligations (other than indemnification Obligations as to which no claim has been asserted), termination of the Revolving Loan Commitments and a release of all claims against the Agents and Lenders, and so long as no suits, actions proceedings, or claims are pending or threatened against any Indemnitee asserting any damages, losses or liabilities that are indemnified liabilities hereunder, each Agent shall deliver to Great Lakes termination statements, mortgage releases, any releases, instruments or documents necessary to release its Liens on any Aircraft, Engines or other flight related assets and other documents necessary or appropriate to evidence the termination of the Liens securing payment of the Obligations.

9.21 Subordination Agreements. Each Lender hereby authorizes each Agent to enter into the Subordination Agreements, to make the representations, warranties and covenants on behalf of the Lenders therein contained, and to take such actions as it is required or authorized to take thereunder (and such actions as are reasonable incidental thereto).
