        and its Subsidiaries (the "Borrowers") (as modified, amended, restated
        and supplemented from time to time, the "Loan Agreement")

Gentlemen:

                As of the date hereof, there is currently outstanding under the
Loan Agreement the following (the "Obligations"):

                1. Billable reserve in the aggregate amount of $30,000,00.(1)

                2. Accrued and unpaid fees due under the Loan Agreement
                   (including the non-refundable Applicable Prepayment premium

                   and interest on Advances through December 30, 2003 of

                3. Advances in the aggregate principal amount of $0.00
                   outstanding as of end of business on December 30, 2003.

         (1) The billable reserve will be used to reimburse the Lender for all

Agreement. If there remains any balance in such reserve after payment of such

At such time, the Lender shall provide to the Borrowers an itemization of such
fees, disbursements and expenses.

                4. Outstanding Letters of Credit in the aggregate amount of
                   $3,252,435.00 to be cash collaterized in the aggregate amount
                   of $3,415,056.75.

                The amount necessary to satisfy the Obligations on the date
hereof totals $4,715,714.76.

                Capitalized terms used herein without definition shall have the
meaning ascribed to such terms in the Loan Agreement.

                Payment of the foregoing sums shall be made from the funds
available in the Borrowers' Loan Account from Collections. Any funds in the
Borrowers' Loan Account in excess of the amount necessary to satisfy the
Obligations set forth herein shall be returned to the Borrowers. Effective as of
such payment, the Borrowers irrevocably terminate the Loan Agreement.

                The Borrowers have proposed that that all Collateral securing
the Obligations be released upon repayment of the above-described Obligations,
in each case, in immediately available funds.

                The Lender agrees that, upon receipt in immediately available
funds (or the cash collateralization of the Obligations in respect of
Outstanding Letters of Credit as provided in paragraph 4 above) of all
above-described Obligations not later than 2:00 p.m. (Atlanta, Georgia time) on
December 30, 2003 and receipt by the Lender of counterparts of this letter
agreement from the Borrowers (i) the Borrowers shall not have any Obligations
under the Loan Agreement except for indemnification obligations that shall
survive until satisfied in full, (ii) all security interests and liens held by
or for the benefit of the Lender shall be released and terminated without any
further action by the Borrowers or the Lender and, at the Borrowers' request,
the Lender (at the sole expense and cost of the Borrowers) will deliver to the
Borrower Uniform Commercial Code termination statements and such other releases
as are reasonably requested by the Borrowers in connection with the release and
termination of security interests and liens under the Loan Documents, (iii) the
Borrowers shall be authorized to file all Uniform Commercial Code termination
statements and such other documents as are necessary to release or terminate any
and all security interests and liens of the Lender in and to any assets of the
Borrowers, including any filings required by the Assignment of Claims Act, 31
USC Section 3727 and (iv) all account control agreements and similar
arrangements entered into pursuant to the Loan Documents shall be terminated and
be of no further force and effect; provided, however, that the foregoing release
of the Lender's security interest shall not apply to any cash collateral held by
the Lender pursuant to that certain letter agreement with respect to letter of
credit reimbursement obligations dated of even date herewith between World
Airways, Inc. and Wells Fargo Foothill, Inc.

                Each Borrower agrees to indemnify the Lender from any and all
loss, cost, damage or expense (including attorneys' fees and legal expenses)
that the Lender may suffer or incur at any time as a result of any non-payment,
claim, refund or dishonor of any checks or other items which have been credited
by the Lender to the account of the Borrowers with the Lender. In addition, each
Borrower agrees to pay to the Lender on demand all costs and

<PAGE>

expenses (including attorneys' fees) incurred in connection with this letter
agreement, and any instruments or documents contemplated hereunder.

                Notwithstanding anything to the contrary contained herein, the
Lender reserves all of its rights in and to any checks or similar instruments
for payment of money heretofore received by the Lender in connection with its
arrangement with the Borrowers, and all of its rights to any monies due
or to become due under said checks or similar instruments and/or all of its
claims hereon.

                Notwithstanding anything to the contrary contained herein, in
the event any payment made to, or other amount or value received by, the
Lender from or for the account of any Borrower is avoided, rescinded, set aside
or must otherwise be returned or repaid by the Lender whether in any bankruptcy,
reorganization, insolvency or similar proceeding involving any Borrower or
otherwise, the indebtedness intended to be repaid thereby shall be reinstated
(without any further action by any party) and shall be enforceable against such
Borrower. In such event, the Borrows shall be and remain liable to the Lender
for the amount so repaid or recovered to the same extent as if such amount had
never originally been received by the Lender.

                Each Borrower represents and warrants that there are no claims,
causes of action, suits, debts, obligations, liabilities, demands of any
kind, character or nature whatsoever, fixed or contingent, which such Borrower
may have, or claim to have, against the Lender, and each Borrower, on behalf of
itself and its shareholders or members and subsidiaries, hereby releases,
remises and forever discharges the Lender, and its agents, servants, employees,
directors, officers, attorneys, accountants, consultants, affiliates,
representatives, receivers, trustees, subsidiaries, predecessors, successors and
assigns (collectively, the "Released Parties") from any and all claims, damages,
losses, demands, liabilities, obligations, actions and causes of action
whatsoever (whether arising in contract or in tort, and whether at law or in
equity), whether known or unknown, matured or contingent, liquidated or
unliquidated, in any way arising from, in connection with, or in any way
concerning or relating to any dealings with any of the Released Parties (other
than claims determined by a court of competent jurisdiction to arise from the
gross negligence or willful misconduct of a Released Party) from the beginning
of time until and through the dates of execution and delivery of this letter.
