PERSONAL & CONFIDENTIAL

Mr. Paul Hoover
Management & Report Technologies, Inc.
2650 Hanson Street
Ft. Myers, FL  33901

Dear Mr. Hoover:

         MercFuel, Inc. ("MercFuel") wishes to acquire a perpetual, exclusive
worldwide license in all intellectual property (including computer hardware and
software) owned or utilized by Management & Report Technologies, Inc. ("MARTI")
as it may be applied to the delivering of aviation fuel. This letter contains
all of the essential terms and conditions under which we agree to acquire the
license of intellectual property interests in MARTI to be used only and
exclusively in the aviation fuel delivery business, and shall be deemed a
binding agreement between the parties. This letter may be followed by an
additional agreement containing these and other terms and conditions, which
other terms and conditions are agreed not to be essential nor necessary to
create a binding agreement.

         1. Acquisition of License; Closing Date. On the terms and conditions
set forth below, MercFuel agrees to acquire, and MARTI shall grant to MercFuel,
on the Closing Date, an exclusive, perpetual, worldwide, license to use, copy or
reproduce, within limitations of existing agreements with other software
vendors, in MercFuel's business defined as the delivery of aviation fuel,
whether for manufacture or otherwise, the hardware, devices, (excluding software
source code and electronic engineering drawings which will be escrowed for the
benefit of MercFuel) and documentation developed by MARTI as of the Closing
Date, and all other intellectual property in connection therewith, including
know-how and processes, for use in the collection of aviation fuel delivery data
and the reconciliation of aviation fuel deliveries. Further, MARTI shall grant
to MercFuel on the Closing Date the exclusive right to sublicense to third
parties in the aviation fuel business, as reasonably determined to be in such
business by MercFuel and MARTI, the software and documentation developed by
MARTI for use in the collection of aviation fuel delivery data and the
reconciliation of aviation fuel deliveries, and shall have submitted to
MercFuel, prior to the Closing Date, an assessment of the applicability of

the hardware and software for use in the collection of aviation fuel delivery
data and the reconciliation of aviation fuel deliveries. MARTI also grants to
MercFuel the right to claim proprietary licensed interests in all technology
licensed hereunder and to license or sublicense the technology under the name
MercFuel, Inc., or under any other name, at the discretion of MercFuel, Inc.,
without any obligation to attribute the technology to MARTI or any other entity
except for purposes required to protect copyright and patent rights and
interests. All rights and licenses granted under or pursuant to this Agreement
are and shall otherwise be deemed to be, for purposes of Section 365(n) of the
U.S. Bankruptcy Code ("Bankruptcy Code"), licenses of rights to "intellectual
property" as defined under Section 101 of the Bankruptcy Code. MercFuel, as
licensee of the applicable rights under this Agreement granted by MARTI, shall
retain and may fully exercise all of its rights and elections under the
Bankruptcy Code. In the event of commencement of a bankruptcy proceeding by or
against either party under the Bankruptcy Code, MercFuel shall be entitled to
complete access to any such intellectual property or embodiments thereof. For
purposes of this Agreement, the "Closing Date" means the effective date of the
Offering (as defined below), provided that all conditions precedent have been
satisfied prior thereto. If all conditions precedent have not been satisfied
prior to the Offering, or if the Offering does not occur prior to December 31,
2001, this agreement shall terminate, without any liability or obligation of
either party hereto. For purposes of this Agreement, the "Offering" constitutes
a public offering of common stock of MercFuel, Inc., with respect to which
MercFuel has previously filed a registration statement on Form S-1 with the
Securities and Exchange Commission, and the term "Distribution" means a
distribution of the common stock of MercFuel, Inc. to the shareholders of
Mercury Air Group, Inc. ("MAG"), the parent corporation of MercFuel, which is
currently planned to occur approximately six months following the date of the
Offering. MARTI hereby acknowledges its understanding that neither the Offering
nor the Distribution may occur due to reasons within or outside the control of
MercFuel and MAG, and that neither MercFuel nor MAG shall have liability to
MARTI or its affiliates on account thereof.

         2. Consideration. The consideration for the acquisition of the license
herein shall consist of (i) cash in the amount of $25,000 (the "Cash
Downpayment") payable by October 1, 2001 and (ii) a $750,000 non-interest
bearing subordinated convertible note (the "Note") payable on the Closing Date,
which Note shall be converted into 125,000 shares of common stock of MercFuel,
upon written notice given by MercFuel following the date of the Distribution.
The Note, if not previously converted, shall be due and payable in twenty-four
equal monthly installments with the first installment due and payable one year
from the date of this letter subject to approvals or restrictions, if any,
imposed by MercFuel's lenders. Subject to approval by the underwriters of the
Offering (as defined below), and subject to acceptance by such underwriters and
by MARTI of a mutually agreeable lock-up period, the common shares underlying
the Note (the "Underlying Shares") shall be registered in the Offering. If the
Underlying Shares are not so registered, and if the Note has not been paid in
whole or in part, then MercFuel shall use its best efforts to register the
Underlying Shares on a Form S-3 as soon as MercFuel becomes eligible to use such
form. If the Cash Downpayment is not made by October 1, 2001, this Agreement
shall be terminated, without any further obligations of the parties hereto.
