WHEREAS, by an Agreement dated as of June 10, 2011 (collectively, together with the amendments and other documents executed in connection therewith, the “Original Agreement”) Great Lakes and RACC agreed, in some specific respects, to modify certain of the “Finance Documents” (which term, as used hereinafter; shall mean the Finance Documents as amended and modified by the Original Agreement);

WHEREAS, the Promissory Notes, as modified by the Original Agreement, require Great Lakes to pay in full the entire remaining balance of principal and interest due under each Promissory Note (the “Balloon Payments”) on August 31, 2011 (the “Amended Balloon Payment Date”) and, as of the date of this Agreement, Great Lakes has disclosed and acknowledges that it is unable to timely and fully pay the Balloon Payments to RACC as required under the Promissory Notes;

WHEREAS, Great Lakes has requested that RACC agree to extend the Amended Balloon Payment Date from August 31, 2011 to October 17, 2011; and

WHEREAS, on and subject to the terms and conditions provided in this Agreement, RACC is willing to agree to so extend the Amended Balloon Payment Date,

NOW, THEREFORE, in consideration of the foregoing premises, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and fully intending to be legally bound by this Agreement, the parties hereto agree as follows:

1. Extension of Balloon Payment Date; Extension Fee.

(a) On the terms and conditions provided in this Agreement, the parties hereto hereby agree that Amended Balloon Payment Date is extended from August 31, 2011 to October 17, 2011 and that the base interest rate on each of the Promissory Notes, with effect on and after September 1, 2011, shall be, and hereby is, increased from 6.75% per annum to 8.75% per annum. Great Lakes irrevocably and unconditionally agrees (i) to make payments of $25,500, as provided in the Original Agreement, on each Promissory Note on or before August 30, 2011, (ii) to make payments of $27,600 on each Promissory Note on or before September 30, 2011, (iii) to make payments of $13,800 on each Promissory Note on or before October 14, 2011, and (iv) to pay any and all amounts outstanding and unpaid, including, without limitation, all principal and accrued interest, on each Promissory Note on or before October 17, 2011. The modification to each of the Promissory Notes agreed to under this Agreement shall be reflected in a Second Amendment to Amended and Restated Promissory Note or a Second Amendment to Amended and Restated Promissory Note (as the case may be) to each Promissory Note dated the date hereof and shall be in the form attached to this Agreement as Exhibit A. For the avoidance of any possible doubt, the payment and performance by Great Lakes of each and all of its obligations under and in connection with, among other things, the Promissory Notes, as amended by the Second Amendment to Amended and Restated Promissory Note or Second Amendment to Second Amended and Restated Promissory Note (as the case may be) provided for under this Agreement, are, and continue to be, secured by each Security Agreement, and each Promissory Note, as so amended, is and constitutes a “Transaction Document”, as that term is defined in the Amended and Restated Restructuring Agreement dated as of March 9, 2007 by and between Great Lakes and RACC. To memorialize that understanding, the parties hereto on the date hereof are entering into a Third Amendment to the Security Agreements, which shall be in the form attached to this Agreement as Exhibit B.

(b) Great Lakes agrees to pay to RACC, on the date hereof, an extension fee in the amount of One Hundred Thousand Dollars ($100,000), which shall be fully earned when paid and not refundable, and which is in addition to paying RACC’s reasonable costs and expenses as hereinafter provided.

2. Continued Effectiveness of Finance Documents; No Waiver; Etc.

(a) Except as expressly modified by this Agreement, the parties hereby confirm and ratify each of the other terms and conditions of the Finance Documents, and agree that all of the provisions of each Finance Document remain in full force and effect and Great Lakes hereby confirms and ratifies each of its obligations under the Finance Documents. The parties also agree that, in addition to any other Event of Default (as defined in the relevant document), any breach of any provision of this Agreement shall constitute an immediate Event of Default under each of the Finance Documents, the Leases (as hereinafter defined) and the Senior Note Documents (as hereinafter defined, and, collectively with the Finance Documents and the Leases, the “GLUX/RACC Documents”).

(b) Great Lakes hereby acknowledges and agrees that except as expressly provided herein, the GLUX/RACC Documents remain in full force and effect and that, if it defaults in any of its obligations to RACC, RACC is fully entitled to exercise any or all of its rights and remedies as provided in, and in accordance with the provisions of, the GLUX/RACC Documents.

(c) Great Lakes hereby acknowledges and agrees that RACC’s agreement to extend the Balloon Payment Date in this Agreement does not constitute a waiver or forgiveness of any obligation and that, in granting the extension under the Original Agreement and the extension provided herein, RACC is not agreeing to, or suggesting in any way, that there will or might be any further extension, accommodation or any waiver of any right or remedy in any of the GLUX/RACC Documents and Great Lakes acknowledges and agrees that it will not assume or rely upon the possibility or prospect of any possible future extension or accommodation by RACC.

(a) Leases. Great Lakes currently is leasing six (6) used Beech 1900D Airliners under six (6) separate Operating Leases (the “Leases”), each of which is identified on Exhibit C, which is attached to this Agreement. As contemplated by the Leases, on or about May 4, 2011 RACC gave Great Lakes a Notice of Termination for each Lease, each of which was modified by a letter dated August 19, 2011, agreed to by Great Lakes and RACC, which provides the date of termination for each Lease. Great Lakes acknowledges its receipt of, and the correctness in all respects and effectiveness of, such amended Notices of Terminations and hereby confirms and ratifies each of its obligations under the Leases. Except for such confirmation and ratification and the provisions of Sections 2 and 4 of this Agreement, this Agreement does not affect the Leases in any way, all of which shall remain in full force and effect, subject, however, to the above-described amended Notices of Termination.

(b) Senior Note. Great Lakes currently is obligated to RACC under a Senior Note dated March 23, 2007 (the “Senior Note”) that is secured by four (4) Aircraft Security Agreements, (the “Embraer Security Agreements” and, collectively with the Senior Note, the “Senior Note Documents”), each of which relates to an Embraer Model EMB-120ER aircraft. Great Lakes acknowledges its obligations under the Senior Note Documents and hereby confirms and ratifies each of its obligations under the Senior Note Documents. Except for such confirmation and ratification and the provisions of Sections 2 and 4 of this Agreement, this Agreement does not affect the Senior Note Documents in any way, each of which shall remain in full force and effect.

All of RACC’s reasonable costs and expenses for preparing this Agreement, any filings or other matters involving this Agreement shall be paid by Great Lakes on the date hereof or, if later invoiced, not later than five (5) days after Great Lakes’ initial receipt thereof.
