 1. Restructuring Agreement.
Reference is hereby made to (i) that certain Restructuring Agreement (as amended and in effect from time to time, the “Restructuring Agreement”), dated as of December 31, 2002, by and between Great Lakes Aviation, Ltd., an Iowa
corporation (the “Debtor”), and Raytheon Aircraft Credit Corporation, a Kansas corporation (“RACC”) and (ii) that certain forbearance extension letter dated as of December 11, 2003 (the “Forbearance Letter”), by and
between the Debtor and RACC. Capitalized terms used and not otherwise defined herein shall have the meanings assigned to them in the Restructuring Agreement. 
  
 2. Promise to Pay. FOR VALUE RECEIVED, the undersigned hereby absolutely and unconditionally promises to pay to the order of RACC, at its
place of business at 101 S. Webb Street, Suite 300, Wichita, Kansas 67207 (together with its successors and assigns hereinafter referred to as “RACC”), in lawful money of the United States of America and in immediately available funds, the
principal sum of TWO MILLION TWO HUNDRED AND FIFTY THOUSAND DOLLARS ($2,250,000.00) (as such amount may be adjusted in accordance with the provisions of Section 3 of the Forbearance Letter, the “Principal Sum”). All payments made pursuant
to this promissory note (this “Promissory Note”) will be made free and clear of, and without deduction for, withholding, setoff, recoupment or counterclaim of any kind. 
  
 3. Interest Rate. In addition to Debtor’s payment of the Principal Sum, Debtor shall pay interest to RACC on the
outstanding Principal Sum at the rate per annum equal to LIBOR plus four hundred (400) basis points. Interest on this Promissory Note shall be payable in cash monthly in arrears commencing on the earlier of: (1) last day of the month during which
the final Group A Aircraft is returned to RACC pursuant to paragraph 3 of the Forbearance Letter (the “Repayment Commencement Date”) or (2) April 30, 2004. The annual rate of interest applicable hereunder from time to time, as specified
above, is referred to herein as the “Interest Rate.” All interest shall be calculated on the basis of a 360-day year and actual days outstanding. Notwithstanding anything set forth in this Promissory Note to the contrary, in 







 no event shall the rate of interest payable pursuant to this Section 3 be higher than the maximum amount permitted under
applicable law. “LIBOR” shall mean the rate of interest determined by RACC at which Dollar deposits for ninety (90) days are offered based on information provided in The Wall Street Journal on the second business day prior to the
date of the issuance of this Promissory Note or the first day of January, April, July and October, as applicable, provided, however, that if the rate described above does not appear in The Wall Street Journal on any applicable interest
determination date, LIBOR shall be the rate determined by RACC in good faith based on the offered rates for deposits in Dollars for ninety (90) days that are then offered by major banks in the London interbank market. LIBOR shall be adjusted on the
first business day of each calendar quarter to reflect any increase or decrease in LIBOR as of that date. 
  
 4. Late Payment Charge. While an Event of Default (as defined below) is continuing, Debtor agrees to pay to RACC interest on the unpaid principal
balance hereunder or other amounts payable hereunder (compounded monthly and payable on demand in respect of overdue amounts) at a rate per annum which is equal to LIBOR plus six hundred basis points (the “Default Interest Rate”) until
such Event of Default has been cured or waived in writing by RACC (after as well as before judgment). 
  
 5. Repayment. The Principal Sum shall be paid to RACC in sixty (60) equal monthly payments at the end of each month commencing on the earlier of :
(1) the last day of the month during which the final Group A Aircraft is returned to RACC pursuant to paragraph 3 of the Forbearance Letter (the “Repayment Commencement Date”) or (2) April 30, 2004, provided, however, that in the event
that the Principal Sum is adjusted in accordance with Section 3 of the Forbearance Letter, the remaining monthly payments after such adjustment shall be adjusted accordingly on an equal basis. All amounts of principal and interest not repaid by
Debtor prior to the last day of the month that is sixty (60) months after the Repayment Commencement Date (the “Due Date”) shall be paid in full on the Due Date. 
  
 6. Taxes. All payments (whether of principal, interest or otherwise) made by Debtor to RACC pursuant to this
Promissory Note will be free and clear of and without deduction for any taxes, levies, duties, charges, fees or withholdings of any nature, provided, however, that taxes based on the net income of RACC are specifically excluded from the provisions
of this Section 6. If Debtor is required by law to make any such deduction or withholding, the sum due from Debtor will be increased to the extent necessary to ensure that RACC receives a sum equal to what it would have received had no such
deduction or withholding been required. Within thirty (30) days after Debtor has made any payment from which it is required by law to make any deduction or withholding, Debtor will deliver to RACC a receipt issued by the applicable tax or other
authority evidencing the deduction or withholding.

 7. Prepayment. The Debtor may prepay this obligation in part or in full at any time without any
premium or penalty. Any partial prepayment shall be applied to the installments of principal in inverse order of maturity and in accordance with Section 11(C) of the Restructuring Agreement. 
  
 8. Covenants. Debtor covenants and agrees that, until the payment and
satisfaction in full of all the obligations of and amounts owed by Debtor under this Promissory Note, Debtor will: 
  
 (a) furnish RACC with such financial information with respect to Debtor or the collateral described in the Security Agreements and in
Section 13 of the Restructuring Agreement (the “Collateral”) as RACC may reasonably request; 
  
 (b) keep true and accurate books of account with respect to the Collateral and to permit RACC or its designated representatives to inspect
the Collateral and the Aircraft and to examine and be advised as to such records upon the request of RACC; 
  
 (c) comply with any law, treaty, rule, regulation or determination of an arbitrator, court, or other governmental authority, in each case
applicable to or binding upon Debtor or affecting any of its property; 
  
 (d) notify RACC promptly in writing of (i) the occurrence of any Default or Event of Default, (ii) any change of name or address of Debtor, (iii) any threatened or pending litigation or similar proceeding affecting

 (e) cooperate with RACC, take such action, execute such documents, and provide such information as RACC may

Note, and any renewals, extensions or changes hereof, including all such Obligations that would become due but for the operation of the automatic stay pursuant to section 362(a) of the Federal Bankruptcy Code and the operation of sections 502(b) and
506(b) of the Federal Bankruptcy Code and including, without limitation, post-petition interest (collectively, the “Obligations”), shall be secured by the Corporate Security Documents, the Group B Security Documents and any other

 10. Purpose of Loan; Usury. Debtor warrants and represents to RACC that this loan is for business
and commercial purposes and not for personal, family, household or agricultural purposes. It is agreed, notwithstanding any provision to the contrary in any of the Transaction Documents, in no event will this Promissory Note require the payment of
interest or charges in excess of the maximum amount permitted by applicable law (the “Maximum Rate”) and the payment of obligations of Debtor under this Promissory Note are hereby limited accordingly. If under any circumstances, whether by
reason of advancement or acceleration of the maturity of the unpaid principal balance hereof or otherwise, the aggregate amounts paid on this Promissory Note shall include amounts which by law are deemed interest and would exceed the Maximum Rate,
Debtor stipulates that payment and collection of such excess amounts shall have been and will be deemed to have been the result of a mistake on the part of both Debtor and RACC, and RACC shall promptly credit such excess (to the extent only of such
payments in excess of the Maximum Rate) against the unpaid principal balance hereof and any portion of such excess payments not capable of being so credited shall be refunded to Debtor. 
  
 11. Waiver. The Debtor hereby waives presentment, demand for payment, notice of non-payment, notice of dishonor, and
all other notices or demands in connection with the delivery, acceptance, performance, default or endorsement of this Promissory Note, protest and impairment of collateral, as well as diligence in collecting this Promissory Note or enforcing any of
the security therefor, and consents to all extensions, deferrals, partial payments and refinancings hereof before or after maturity.

due date of such payment; 
  
 (b) Debtor shall
fail to perform any term, covenant or agreement contained in any of the Transaction Documents and such failure shall continue for thirty (30) days after written notice;

 j) Debtor (i) sells, transfers or disposes of all or substantially all of its respective stock, assets or property, (ii) becomes the
subject of, or engages in, a leveraged buy-out, or (iii) terminates its existence by merger, reorganization or consolidation.

 (2) In the case of any Event of Default other than under clauses (f) or (g), RACC may, by
written notice to Debtor, declare the unpaid principal amount of this Promissory Note and all other amounts payable hereunder, to be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are

performance obligations under this Promissory Note and the other Transaction Documents are absolute and unconditional. Any claim that Debtor may now or hereafter have against RACC or any affiliate thereof arising out of or in connection with the
Aircraft, any of the other Collateral or any other matter shall not affect or excuse the unconditional obligation of Debtor to make any payment required to be made to RACC under the Transaction Documents, and shall not be used or asserted as a
defense to payment of such obligation or as set-off, counterclaim or deduction against such payment. RACC shall have no obligation or responsibility with respect to any dispute that may arise between Debtor and any such foregoing person, and no such
dispute shall prevent RACC from taking such action as it may deem appropriate in order to preserve, protect or enforce its rights hereunder. 
  
 14. Debtor’s Agreement to Pay Enforcement Costs, Etc. Debtor further agrees to pay to RACC, on demand, all costs and expenses (including court

due until payment, whether before or after judgment, at the Default Interest Rate, provided that if such interest exceeds the maximum amount permitted to be paid under applicable law, then such interest shall be reduced to such maximum permitted
amount. 
  
 15. Waiver of Default. No waiver by RACC of any
default shall be effective unless in writing, nor operate as a waiver of any other default or of the same default in the future.
