Dear Madams/Sirs:

The parties hereto agree that for all purposes of the Lease, Section 8.7(a)(vi)
of the CTA shall be deemed to be amended by adding at the end thereof:

"In addition to the foregoing requirements, so long as Aviation Financial
Services Inc. or an Affiliate of Aviation Financial Services Inc. is the Lessor,
Lessee shall not, during the Term, enter into any merger with or into or
consolidation with, or sell, convey, transfer, lease or otherwise dispose of in
one or a series of transactions all or substantially all of its assets as an
entirety to any Person, unless the surviving corporation or Person which
acquires by purchase, conveyance, transfer or lease all or substantially all of
the assets of the Lessee as an entirety (A) is a domestic corporation organized
and existing under the laws of the United States or any State of the United
States, (B) is a Citizen of the United States, (C) is a Certificated Air
Carrier, (D) if not the Lessee, executes a duly authorized, legal, valid,
binding, and enforceable agreement, reasonably satisfactory in form and
substance to Lessor, Owner and the Financing Parties' Representative, containing
an effective assumption of all of the Lessee's, as applicable, obligations
hereunder and under the Engine Lease Agreement, and each other document
contemplated hereby or thereby and delivers such instrument to the Lessor, Owner
and the Financing Parties' Representative, (E) provides an opinion from counsel
(which counsel may be the Lessee's General Counsel) delivered to the Lessor,
Owner and the Financing Parties' Representative, which opinion shall be
reasonably satisfactory to the



Lessor, and an officer's certificate (which may rely, as to legal matters, on
such legal opinion), each stating that such merger, consolidation, conveyance,
transfer, lease or other disposition and the instrument noted in Section
8.7(a)(vi)(B) of the CTA complies with this letter agreement and Section
8.7(a)(vi) of the CTA, that such instrument is a legal, valid and binding
obligation of, and is enforceable against, such survivor or Person, and that all
conditions precedent herein provided for relating to such transaction have been
complied with, and (F) such survivor or Person makes such filings and recordings
with the FAA as may be required pursuant to part A of subtitle VII of Title 49,
United States Code to evidence such merger or consolidation; PROVIDED THAT, no
such merger, consolidation or conveyance, transfer or lease shall be permitted
if (1) immediately after giving effect to such consolidation, merger, purchase,
conveyance, transfer, lease or other disposition, an Event of Default shall have
occurred and be continuing or (2) the surviving Person in such transaction has a
tangible net worth, as determined in accordance with generally accepted
accounting principles immediately following such transaction, of less than
seventy-five percent (75%) of Lessee, as measured immediately prior to such
transaction.

In addition to the foregoing requirements, so long as Aviation Financial
Services Inc. or an Affiliate of Aviation Financial Services Inc. is the Lessor
(A) during the first five (5) years of the Term, the Lessee shall not enter into
any merger with or into or consolidation with, or sell, convey, transfer, lease
or otherwise dispose of in one or a series of transactions all or substantially
all of its assets to any Person nor shall Wexford Air Holdings, Inc. (the
"Wexford Shareholder") sell any of its shares of common stock in the Lessee
(collectively, a "Transaction") without the prior written consent of the Lessor,
such consent not to be unreasonably withheld, unless: (i) following such
Transaction, the Wexford Shareholder is the shareholder owning the greatest
number of shares of common stock of the Lessee or other surviving entity; or
(ii) the acquiring or successor entity in such Transaction is a Certificated Air
Carrier with a tangible net worth of not less than Fifty Million Dollars
($50,000,000.00) or a Group III air carrier as determined under 14 CFR 241,
Section 04 (or, if such determination has not been made, an air carrier with
annual operating revenues of One Billion Dollars ($1,000,000,000.00); or (iii)
immediately following the Transaction, Lessee receives and retains net proceeds
of at least Twenty Five Million Dollars ($25,000,000.00); and (B) clause (2) of
the proviso in the immediately preceding paragraph shall not apply during the
first five (5) years of the Term with respect to any Transaction that otherwise
fully satisfies any one of the conditions set forth in subclauses (i), (ii), or
(iii) in clause (A) of this paragraph."

The agreement stated in this letter is for the sole benefit of Aviation
Financial Services Inc. and its Affiliates and shall terminate if at any time
Aviation Financial Services Inc. or an Affiliate ceases to be the Lessor. Each
party agrees that it will not disclose the terms of this letter (other than to
its accountants, attorneys, agents or consultants), including to potential
assignees, except as required by law.
