ARTICLE 2

RETURN OF MESA AIRCRAFT

Section 2.1      Return of Mesa Aircraft. Prior to the date of this Agreement, the Mesa Aircraft have been ferried by Gulfstream to a location specified by RACC.

Section 2.2      Termination of the Assigned Leases. Prior to the date of this Agreement, Gulfstream and RACC executed an FAA lease termination (the “Lease Terminations”) of each of the four Assigned Leases. Gulfstream and RACC agree to perform all required Cape Town Treaty formalities necessary to evidence the termination of the Assigned Leases. Upon execution of the Lease Terminations, the contractual lease payments under the Assigned Leases for the period from August 18, 2008 through the Closing Date have been forgiven by RACC and shall not be owed by Gulfstream.

Section 2.3      Insurance and Risk of Loss. At 5:00 P.M. (Eastern) on the date of execution by Gulfstream and RACC of the Lease Terminations, risk of loss with respect to the Mesa Aircraft passed to RACC and Gulfstream’s obligations to insure the Mesa Aircraft terminated.

Section 2.4      Mesa Return Costs. RACC either has incurred or will incur more than $700,000 in costs and expenses, as has been demonstrated to Gulfstream (the “Mesa Return Costs”), in connection with bringing the Mesa Aircraft into compliance with the return conditions for the Mesa Aircraft set forth in Article 17 of each respective Assigned Lease. The parties are settling all amounts relating to the Mesa Return Costs for $700,000, even though the actual amount of costs incurred by RACC in connection with the return of the Mesa Aircraft will exceed $700,000. The Mesa Return Costs shall be paid as provided in Section 3.1 below.

ARTICLE 3

REPAYMENT OF AMOUNTS OWED

Section 3.1      Repayment. Gulfstream shall repay the amounts owed to RACC as follows:

(a)       Closing Date Payment. On or prior to the Closing Date (as defined in Section 7.1 below), Gulfstream shall pay to RACC $250,0000 (the “Closing Date Payment”) by delivery of cash payable by wire transfer to the RACC account to which Gulfstream makes its

monthly payment, or to another account if one is designated by RACC at least three (3) days prior to the Closing Date. The $250,000 payment shall be applied to reduce the amount owed for the Group A Costs. RACC and Gulfstream acknowledge that $100,000 was paid to RACC on November 21, 2008, meaning that a balance of $150,000 is due on the Closing Date with respect to the Closing Date Payment.

(b)       Additional Payments. Gulfstream shall make (i) a payment of $150,000 to RACC on or prior to March 31, 2009 and (ii) a payment of $135,468.77 to RACC on or prior to June 30, 2009, in each case by delivery of cash payable by wire transfer to the RACC account to which Gulfstream makes its monthly payment, or to another account if one is designated by RACC at least ten (10) days prior to the scheduled payment date. Each of the payments provided for in clauses (i) and (ii) of the preceding sentence shall be applied against the Group A Costs. Upon RACC’s receipt of the payments referred to in Section 3.1(a) and clauses (i) and (ii) of this Section 3.2(b), the Group A Costs shall be paid in full.

(c)       Cash Sweep.

(i)        Commencing with the fiscal quarter ending March 31, 2009, Gulfstream shall make payments to RACC through a quarterly sweep of an amount equal to twenty-five percent (25%) of the Excess Cash (as defined below) of Gulfstream (the “Cash Sweep”). Any amounts to be paid pursuant to the Cash Sweep shall be paid to RACC by not later than the thirtieth (30th) day following the end of each fiscal quarter of Gulfstream and shall be accompanied by a written certification calculating such amount in reasonable detail that is signed by the Chief Executive Officer and Chief Financial Officer of Gulfstream. “Excess Cash” shall mean, as of the end of each fiscal quarter, an amount (if positive) equal to Gulfstream’s available cash and cash equivalents as of such date in excess of (A) for the fiscal quarter ending March 31, 2009, $1,150,000, (B) for the fiscal quarter ending June 30, 2009, $1,300,000 and (C) for the fiscal quarter ending September 30, 2009 and each fiscal quarter thereafter, $1,000,000, in each case without taking into account any revenues or expenses from operations or activities not conducted by Gulfstream as of September 30, 2008.

(ii)       All amounts received pursuant to the Cash Sweep shall be applied (A) first, to the Mesa Return Costs until the Mesa Return Costs have been repaid in full, (B) second, in an amount not to exceed $5,000,000, to be held by RACC as a credit to reduce Gulfstream’s obligation to satisfy end-of-lease return conditions set forth in the Existing Leases and, to the extent not satisfied, any other obligations of Gulfstream to RACC and (C) third, unless previously paid, to all other obligations and indebtedness owed to RACC. RACC shall retain all of those payments, which, upon their receipt, shall be the exclusive property of RACC and Gulfstream shall not have any interest in those funds (other than to the extent Gulfstream is entitled to a refund of such funds pursuant to subparagraph (iii)(B) below). As such, the funds shall be commingled with RACC’s funds generally and will not in any case be held separate or apart.

(iii)      RACC shall provide Gulfstream with a written reconciliation of all amounts expended by RACC in connection with the satisfaction of the Mesa Return Costs and the payment of other unsatisfied obligations owing to RACC. To the extent

that the satisfaction of any Mesa Return Costs and the payment of other amounts owing to RACC is (A) more than the amounts paid under the preceding subparagraph (ii), Gulfstream shall immediately upon demand pay the excess amount to RACC and (B) less than the amounts paid under the preceding subparagraph (ii), RACC shall immediately, without demand by Gulfstream, pay the excess amount to Gulfstream.

(d)       Past Due Rental Payments. The Past Due Rental Payments shall remain owing and due and payable and the Existing Leases remain in default and shall remain in default unless and until such Past Due Rental Payments and late payment interest thereon as provided in the Existing Leases are paid in full. RACC has reserved, and is reserving, all of its rights and remedies in connection with the Past Due Rental Payments, which remain payable on demand.

Section 3.2      Reinstatement Event. If at any time following the Closing Date, a Reinstatement Event (as defined below) occurs, then (a) all amounts that would have been due and owing from Gulfstream to RACC but for the operation of this Agreement (the “Unpaid Obligations”), including, but not limited to, the Past Due Rental Payments and any and all amounts relating to the return of the Mesa Aircraft that would have been payable but for the agreement to settle the Mesa Return Costs for $700,000, shall be reinstated in full and all of Gulfstream’s obligations under the Leases shall continue with the same force and effect, in such case with respect to the amount of the Unpaid Obligations as if this Agreement had never been executed and delivered and (b) the full amount of the Unpaid Obligations that, but for the operation of this Agreement, would have been payable by Gulfstream to RACC pursuant to the Leases after the Closing Date shall become immediately due and payable by Gulfstream, with interest at the applicable past due rate on such payments. For purposes of this Section 2.3, a “Reinstatement Event” is defined as one or more of the following: (x) a case shall have been commenced under Chapter 7 of the United States Bankruptcy Code (11 U.S.C. § 101 et seq.) (the “Bankruptcy Code”) with respect to Gulfstream; provided that, if such case is an involuntary case, such case shall not, within ninety (90) days, have been withdrawn, dismissed or converted to a case under Chapter 11 of the Bankruptcy Code; (y) following the commencement of (or conversion to) any case under Chapter 11 of the Bankruptcy Code with respect to Gulfstream, the rejection or attempted rejection of this Agreement by Gulfstream, Gulfstream as debtor-in-possession or any bankruptcy trustee or any challenge to this Agreement is filed in that proceeding by any other party or person; or (z) following the commencement of (or conversion to) any case under Chapter 11 of the Bankruptcy Code with respect to Gulfstream, Gulfstream, Gulfstream as debtor-in-possession, any bankruptcy trustee or any other party or person shall seek termination of or otherwise challenge the validity of this Agreement and/or challenge or seek to avoid the transactions or payments contemplated hereby, including, without limitation, attacking any of the transactions or payments hereunder as being preferential or involving or constituting fraudulent transfers.

Section 5.3      Propeller Exchanges.

(a)       Gulfstream and RACC acknowledge that Gulfstream has entered into propeller exchange & pooling agreements, including Gulfstream’s present agreement with the Hartzell Propeller Company. Any and all propellers that may have or will be exchanged in the normal course of business shall be subject to a properly executed exchange agreement acceptable to RACC with all rights of title flowing with the received propeller in the form of a bill of sale

and that propeller shall be free of any liens or encumbrances at the time of the exchange. In addition, Gulfstream shall promptly provide RACC with notice of all such exchanges, and Gulfstream agrees to cooperate fully to execute and deliver any and all necessary amendments to the Leases recorded with the FAA or other FAA filings pertaining to the Leased Aircraft with respect to any such replacement propellers that RACC may request.

Gulfstream shall at all times remain current with all payment obligations and in full compliance with each and every one of its other obligations under the Existing Leases, the Collateral Assignment and this Agreement (collectively, the “Transaction Documents”) and under the P&W Agreement, including, but not limited to, paying monthly lease payments under the Existing Leases of $21,000 per Leased Aircraft per month, which monthly rental payments are due on the sixth day of each month, with the first payment after the Closing Date being due on January 6, 2009.

Section 6.4      Title to Leased Aircraft. For the avoidance of any possible doubt, Gulfstream acknowledges and agrees that the Leased Aircraft are owned by RACC and have been leased to Gulfstream, that Gulfstream has no claim to title or any other ownership interest in the Leased Aircraft and that Gulfstream will not place, incur, permit or suffer any lien or encumbrance of any type or kind on or with respect to the Leased Aircraft.

Section 6.5      Further Assurances. Gulfstream will, at RACC's reasonable request, furnish RACC such information and execute and deliver to RACC such documents and do all such acts and things as RACC may reasonably request as are necessary or appropriate to assist RACC in establishing, registering, validating and maintaining valid ownership interests in the Leased Aircraft and to assure that the Leased Aircraft are properly titled and registered and the security and ownership interests, as applicable, and International Interests are perfected to RACC's satisfaction. Gulfstream will pay the cost of filing all appropriate documents in all public offices where RACC deems such filings necessary or desirable. In order to evidence RACC’s ownership interest in the Leased Aircraft, Gulfstream authorizes the filing by RACC, at Gulfstream’s expense, of Uniform Commercial Code financing or continuation statements, or amendments thereto, and Gulfstream will execute and deliver to RACC such other instruments or notices, in each case as may be necessary or as RACC may reasonably request, in order to perfect and preserve the ownership interests and security interests granted or purported to be granted hereby or thereby.

Section 6.6      Arrangements with Other Creditors. The terms of any repayment of indebtedness owing to other creditors of Gulfstream shall be on terms that are no more favorable than the repayment amounts set forth in the revised cash flow projections provided by Gulfstream to RACC on December 2, 2008 and certified by the CEO and CFO of Gulfstream as

of the Closing Date, which cash flow projections were presented to RACC as the basis on which to undertake the restructuring provided for in this Agreement; provided, however, that Gulfstream shall be permitted to make payments to its other creditors to the extent that such payments are required to be made pursuant to a final, unappealable judgment issued by a court of competent jurisdiction.
