         FOR VALUE RECEIVED, the undersigned, MERCURY AIR GROUP, INC., a
corporation organized under the laws of Delaware (the "Borrower"), hereby
promises to pay to the order of ALLIED CAPITAL CORPORATION, a Maryland

sum of Twenty Four Million Dollars ($24,000,000) on December 31, 2005 (the
"Maturity Date"), with interest thereon from time to time as provided herein.

         1. Purchase Agreement. This Senior Subordinated Promissory Note (the
"Note") is issued by the Borrower pursuant to the Securities Purchase Agreement
dated as of September 10, 1999 by and between the Borrower and Allied, as
assignee of WMF, as amended (the "Purchase Agreement"), and is subject to the
terms thereof. This Note, together with all other promissory notes issued under
the Purchase Agreement, and all promissory notes issued pursuant to paragraph 13
hereof or any provision of the Purchase Agreement are hereinafter referred to as
the "Notes." The Holder is entitled to the benefits of this Note and the
Purchase Agreement, as it relates to the Note, and may enforce the agreements of
the Borrower contained herein and therein and exercise the remedies provided for
hereby and thereby or otherwise available in respect hereto and thereto.
Capitalized terms used herein without definition are used herein with the
meanings ascribed to such terms in the Purchase Agreement.

         2. Interest.

                  (a)      Basic Interest. The Borrower promises to pay interest
on the principal amount of this Note at the rate of 12% per annum. The Borrower
shall pay accrued interest quarterly on each January 1, April 1, July 1, and
October 1 of each year, or, if any such date shall not be a Business Day, on the
next succeeding Business Day to occur after such date (each date upon which
interest shall be so payable, an "Interest Payment Date"). Interest on this Note
shall be paid by wire transfer of immediately available funds to an account at a
bank designated in writing by the Holder. In the absence of any such written
designation, any such Interest payment shall be deemed made on the date a check
in the applicable amount payable to the order of Holder is received by the
Holder at its last address as reflected in Borrower's note register; if no such
address appears, then to the Holder in care of the last address in such note
register of any predecessor holder of this Note (or its predecessor), In
addition to cash interest, during the period beginning on January 1, 2004 and
ending on June 30, 2004, the interest rate on this Note shall increase by a rate
of 1% per annum for each month. Interest in excess of 12% per annum shall accrue
and be added to principal, and shall not be payable in cash. This increase in
interest rate shall take effect on the last day of each month from January 31,
2004 through June 30, 2004, inclusive. Interest on this Note shall accrue from
and including the date of issuance through and

                                       2


until repayment of the principal and payment of all accrued interest in full.
Interest shall accrue and be computed on the basis of a 360-day year of twelve
30-day months.

                  (b)      Default Rate of Interest. Notwithstanding the
foregoing provisions of this Section 2, but subject to applicable law, any
overdue principal of and overdue interest on this Note shall bear interest,
payable on demand in immediately available funds, for each day from the date
payment thereof was due to the date of actual payment, at a rate equal to the
rate of interest otherwise in effect pursuant to the first sentence of this
Section 2 plus 2% per annum, and, upon and during the occurrence of an Event of
Default (as hereinafter defined), this Note shall bear interest, from the date
of the occurrence of such Event of Default until such Event of Default is cured
or waived, payable on demand in immediately available funds, at a rate equal to
the rate of interest otherwise in effect pursuant to the first sentence of this
Section 2 plus 2% per annum. Subject to applicable law, any interest that shall
accrue on overdue interest on this Note as provided in the preceding sentence
and shall not have been paid in full on or before the next Interest Payment Date
to occur after the Interest Payment Date on which the overdue interest became
due and payable shall itself be deemed to be overdue interest on this Note to
which the preceding sentence shall apply.

                  (c)      Maximum Interest. The maximum interest payable on
this Note pursuant to paragraphs (a) and (b) above is 18% per annum.

                  (d)      No Usurious Interest. In the event that any interest
rate provided for herein shall be determined to be unlawful, such interest rate
shall be computed at the highest rate permitted by applicable law. Any payment
by the Borrower of any interest amount in excess of that permitted by law shall
be considered a mistake, with the excess being applied to the principal of this
Note without prepayment premium or penalty; if no such principal amount is
outstanding, such excess shall be returned to Borrower.

         3. Mandatory Prepayment.

                  (a) Public Offerings. Subject to the Subordination Agreement
         dated December 30, 2002 among the Company, Allied, as assignee of WMF,
         and Foothill Capital Corporation (the "Subordination Agreement"), upon
         the consummation of a Public Offering (as hereinafter defined), the
         Borrower shall, at the election of the Holder, prepay the outstanding
         principal amount of this Note (together with interest accrued thereon)
         immediately following receipt by the Borrower, or any of its
         Subsidiaries of the Net Cash Proceeds of such Public Offering. For the
         purposes hereof, "Public Offering" means the sale by the Borrower, or
         any of its Subsidiaries of its equity securities (other than (i) stock
         options or warrants to acquire Common Stock awarded to employees and
         directors pursuant to incentive compensation plans or agreements with
         such Persons in an aggregate amount for all such options and warrants
         not to exceed $250,000 per annum, and (ii) stock issued to a seller
         party to, and as consideration for a Permitted Acquisition) pursuant to
         a registration statement (other than on Form S-4 or S-8) or otherwise

         which contemplates resale of the securities issued under Rule 144A
         under the Securities Act, in which the issuer receives any Net Cash
         Proceeds. For the purposes hereof, "Net Cash Proceeds" means (x)

                                       3


         the cash proceeds in respect of a Public Offering minus (y) all costs
         of sale, underwriting or brokerage costs and taxes paid or payable as a
         result thereof by the Borrower or any of its Subsidiaries. The
         foregoing notwithstanding, until all Senior Indebtedness to which this
         Note is subordinated shall be paid in full, the amount of Net Cash
         Proceeds which the Borrower shall be obligated to pay under this
         Section 3(a) to the Holder as a prepayment of this Note at the election
         of the Holder, shall be limited as set forth in the Subordination
         Agreement.

                  (b) Change of Control. Subject to the Subordination Agreement
         upon the occurrence of a Change of Control (as hereinafter defined),
         the Borrower shall, at the election of the Holder, prepay the
         outstanding principal amount of this Note (together with interest
         accrued thereon), within five Business Days after the occurrence of
         such Change of Control. For the purposes hereof, "Change of Control"
         means (i) any transaction or series of transactions in which any Person
         or group, other than WMF, CFK Partners or any of their respective
         affiliates becomes the beneficial owner of 35% or more of the then
         outstanding capital stock of the Borrower or of any of its
         Subsidiaries, the operations of which would constitute a material part
         of the business or operations of the Borrower and all of its
         Subsidiaries, taken as a whole, (ii) the sale of all or substantially
         all of the assets of the Borrower or of any of its Subsidiaries, the
         operations of which would constitute a material part of the business or
         operations of the Borrower and all of its Subsidiaries, taken as a
         whole, (iii) the liquidation of the Borrower or any of its
         Subsidiaries, the operations of which would constitute a material part
         of the business or operations of the Borrower and all of its
         Subsidiaries, taken as a whole, other than transactions defined as
         Permitted Financing Transactions in, and entered into in compliance
         with, the Purchase Agreement, and/or (iv) the combination of the
         Borrower or of any of its Subsidiaries, the operations of which would
         constitute a material part of the business or operations of the
         Borrower and all of its Subsidiaries, taken as a whole, with another
         entity, as a result of which (A) any Person or group, other than WMF,
         CFK Partners or any of their respective affiliates becomes the
         beneficial owner of 35% or more of the then outstanding capital stock
         of the combined entity or (B) the directors of the Borrower or such
         Subsidiary, as the case may be, constitute less than a majority of the
         Board of Directors of the combined entity.

                  (c) Notice. The Borrower shall give written notice to the
         Holder of any mandatory prepayment pursuant to this Section 3 at least

         such prepayment, and reasonable out-of-pocket costs and expenses
         (including, without limitation, reasonable fees, charges and

                                       4


         prepayment; provided, however, each prepayment of less than the full
         outstanding balance of the principal amount of this Note shall be in an

         so called for prepayment, at the outstanding principal amount thereof

         accrued and unpaid thereon to the date fixed for such prepayment,
         together with the costs and expenses referred to in Section 4(a).

                  (c) All optional prepayments under this Section 4 shall
         include payment of accrued interest on the principal amount so prepaid
         and shall be applied first to all costs, expenses and indemnities
         payable under the Purchase Agreement, then to payment of default
         interest, if any, then to payment of accrued interest, and thereafter
         to principal.

         Note to be immediately due and payable. Upon such declaration, such
         principal and interest shall become immediately due and payable. The
         Holder may rescind an acceleration and its consequences if all existing
         Events of Default have been cured or waived, except nonpayment of
         principal or interest that has become due solely because of the
         acceleration, and if the rescission would not conflict with any
         judgment or decree. Any notice or rescission shall be given in the
         manner specified in Section 7.2 of Amendment No. 4 to the Purchase
         Agreement.

         7. Suits for Enforcement.

                  (a) Subject to the Subordination Agreement upon the occurrence

         proceed to protect and enforce its rights hereunder by suit in equity,
         action at law or by other appropriate proceeding, whether for the
         specific performance of any covenant or agreement contained in the
         Purchase Agreement or this Note or in aid of the exercise of any power
         granted in the Purchase Agreement or this Note, or may proceed to
         enforce the payment of this Note, or to enforce any other legal or
         equitable right of the Holders of this Note.

                  (b) In case of any default under this Note, the Borrower will

         Article 7 of the Purchase Agreement.

         8. Remedies Cumulative. No remedy herein conferred upon the Holder is
intended to be exclusive of any other remedy and each and every such remedy
shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise.

         9. Remedies Not Waived. No course of dealing between the Borrower and
the Holder or any delay on the part of the Holder in exercising any rights
hereunder shall operate as a waiver of any right.

         10. Transfer.

                  (a) The term "Holder" as used herein shall also include any
         transferee of this Note whose name has been recorded by the Borrower in
         the Note Register (as defined). Each transferee of this Note

         exemption from the registration requirements of the Securities Act.

                  (b) The Borrower shall maintain a register (the "Note
         Register") in its principal offices for the purpose of registering the
         Note and any transfer or partial transfer thereof, which register shall
         reflect and identify, at all times, the ownership of record of any
         interest in the Note. Upon the issuance of this Note, the Borrower
         shall record the name and address of the initial purchaser of this Note
         in the Note Register as the first Holder. Upon surrender for
         registration of transfer or exchange of this Note at the principal
         offices of the Borrower, the Borrower shall, at its expense, execute
         and deliver one or more new Notes of like tenor and of denominations of
         at least $500,000 (except as may be necessary to reflect any principal
         amount not evenly divisible by $500,000 of a like aggregate principal
         amount, registered in the name of the Holder or a transferee or
         transferees. Every Note surrendered for registration of transfer or
         exchange shall be duly endorsed, or be accompanied by written
         instrument of transfer duly executed by the Holder of such Note or such
         holder's attorney duly authorized in writing.

                  (c) This Note may be transferred or assigned, in whole or in
         part, by the Holder at any time, except that Holder agrees not to
         transfer this Note or any interest therein so long as the Stock
         Purchase Agreement is in effect.

         11. Replacement of Note. On receipt by the Borrower of an affidavit of
an authorized representative of the Holder stating the circumstances of the
loss, theft, destruction or mutilation of this Note (and in the case of any such
mutilation, on surrender and cancellation of such Note), the Borrower, at its
expense, will promptly execute and deliver, in lieu thereof, a new Note of like
tenor. If required by the Borrower, such Holder must provide indemnity
sufficient in the reasonable judgment of the Borrower to protect the Borrower
from any loss which they may suffer if a lost, stolen or destroyed Note is
replaced.

         12. No Novation. All of the terms, covenants and conditions of the
Original Note shall continue, except as specifically amended and restated
hereby. This Note does not extinguish the outstanding indebtedness and is not
intended to be a substitution or novation of the original indebtedness or
instruments evidencing the same, all of which shall continue in full force and
effect except as specifically amended and restated hereby or by instruments
executed concurrently herewith.

         13. Covenants Bind Successors and Assigns. All the covenants,
stipulations, promises and agreements in this Note contained by or on behalf of
the Borrower shall bind its successors and assigns, whether so expressed or not.
