$100,000

IRVINE, CALIFORNIA                               January 28, 1997

         FOR VALUE RECEIVED, and intending to be legally bound, the
undersigned, AVIATION DISTRIBUTORS, INC., a Delaware Corporation ("the
Corporation"), promises to pay to the order of Mark W. Ashton  ("Holder") at
23015 Cecelia Street, Mission Viejo, California 92691, or at such other place,
either within or without the State of California, as Holder may from time to
time designate in writing, the principal sum of $100,000, on the Maturity Date,
as defined below, together with simple interest on the unpaid principal balance
at the interest rate of 14% per annum, non-compounded, at such times and in the
manner provided below.

         1.   PAYMENT OF INTEREST AND PRINCIPAL.  The principal amount of this
Note shall be due and payable on the Maturity Date, as defined below, and shall
bear interest at the rate of 14% per annum, non-compounded, payable on the last
day of each month.   On the Maturity Date, all accrued but unpaid principal and
simple interest shall be due and payable.

Holder shall have the right to accelerate the maturity of this Note (including
all interest, principal and any other amounts due under this Note) upon an Event
of Default, as provided in paragraph 3 hereof.

         2.   MATURITY DATE.  The "MATURITY DATE" shall be the earlier of (a)
October 27, 1997, and (b) the date on which the Corporation has consummated an
initial public offering of the Corporation's common stock, par value $.01 per
share.

         3.   PREPAYMENT.  The undersigned may, without the prior written
consent of Holder, prepay the unpaid balance of principal under this Note in
whole or in part, at any time or times.  Any such prepayment shall first be



applied against accrued but unpaid interest and next against the principal
balance then due under this Note.

         4.   ACCELERATION.  All of the following constitute "EVENTS OF
DEFAULT":

              (a)  Should default be made in the payment of any installment
when due hereunder and remain uncured after 10 days written notice from Holder
to the undersigned;

              (b)  Should any other default occur hereunder and remain uncured
after 30 days written notice from Holder to the undersigned; or

              (c)  Any bankruptcy or insolvency of the undersigned.

         If there is an Event of Default, then the whole sum of principal and
interest shall, upon written election of Holder delivered to the undersigned,
become due and payable within 10 days of the date of such notice.

         5.   MISCELLANEOUS.  Principal and interest shall be payable in lawful
money of the United States.  Payments hereunder shall be credited first to
interest and then to principal.  Nothing contained in this Note shall be deemed
to require the payment of interest or other charged by the undersigned in excess
of the amount which Holder may lawfully charge under the applicable usury laws.
Interest shall be computed on the basis of a 360-day year and a 30-day month and
shall be calculated as annual simple interest, on a non-compounded basis.  In
the event that the interest and other charges provided herein shall exceed such
lawful charge, then the amount of interest and other charges payable hereunder
by the undersigned shall be reduced to the maximum amount of such lawful charge.
In the event Holder employs counsel to collect this obligation, the undersigned
agrees to pay reasonable costs and attorneys' fees for the legal services
involved.  Paragraph headings shall not be used in construing this Note.  The
validity and construction of this Note and all matters pertaining thereto are to
be determined according to the laws of the State of California.

         6.   NOTICE.  Any notice, demand or document which any party is 
required or may desire to give or deliver to the other shall be in writing 
and may be personally delivered or sent by mail, postage prepaid (either by
