as the "YA Bridge Debentures");

valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

         1. The salary payable by the Company to the Executive shall be reduced

amounts due and owing under YA Bridge Debentures and the New Convertible
Debentures (collectively, the "Bridge Loans") are repaid in full (the "Repayment
Date") at which time the Executive's salary shall be restored to its prior
level.

                                      -1-

pursuant to Section 2 of this Agreement but rather to have such Executive's

Loans have been reduced to $5.0 million or less.

         4. "VWAP" is defined to mean the volume weighted average price of the

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

1. The Subordinated Loan and any and all documents entered into in connection
therewith shall be and hereby are subordinated and the payment thereof is
deferred until the full and final payment in cash of the YA Loan. The YA Lien
shall be senior to the Subordinated Lien irrespective of the time of the
execution, delivery or issuance of any thereof or the filing or recording for
perfection of any thereof or the filing of any financing statement or
continuation statement relating to any thereof. The Borrower shall not be
permitted to pay, and the Subordinated Lenders shall not be permitted to
receive, any payments (whether regularly scheduled payment of interest,
principal, or otherwise) on the Subordinated Loan unless or until the YA Bridge

2. After the YA Bridge Loan has been paid in full, the Borrower shall be
permitted to pay, and the Subordinated Lenders shall be permitted to receive,
any regularly scheduled payment of interest or principal on the Subordinated
Loan so long as (i) at the time of such payment, or after giving effect thereto,
no default has occurred and is continuing under any of the YA Loans, and (ii)
such payment is made solely from funds received in a financing or capital
raising transaction and not out of any cash receipts, funds generated from the

airline).

3. The subordination described in paragraph 1 above shall apply to all existing
and future advances of funds to the Borrower by YA. In further consideration of

price of $0.01 per share, 156,250 of the warrants issued to Marable in
connection with the Marable Loan shall be re-priced to an exercise price of
$0.01 per share, and 62,500 of the warrants issued to Lenihan in connection with
the Lenihan Loan shall be re-priced to an exercise price of $0.01 per share.

4. The terms of the Subordinated Loans (including, without limitation, the
conversion price of any convertible debentures and the exercise price of any
warrants issued in connection with the Subordinated Loan) shall not be adjusted
based on any terms granted to YA under the YA Loan, and no adjustment or
modification to the Subordinated Loan or any documents entered into connection
therewith shall be made without YA's prior written consent.

5. The maturity date of the Subordinated Loan shall be extended to October 31,
