     FOR VALUE RECEIVED, the undersigned, AVIATION SALES DISTRIBUTION SERVICES
COMPANY, a Delaware corporation, AEROCELL STRUCTURES, INC., an Arkansas
corporation, AVS/M-2, INC., a Delaware corporation, WHITEHALL CORPORATION, a
Delaware corporation, TRIAD INTERNATIONAL MAINTENANCE CORPORATION, a Delaware
corporation, AVS/M-3, INC., an Arizona corporation, CARIBE AVIATION, INC., a
Florida corporation, AIRCRAFT INTERIOR DESIGN, INC., a Florida corporation,
AVIATION SALES LEASING COMPANY, a Delaware corporation, and TIMCO ENGINE CENTER,
INC., a Delaware corporation (each a "Borrower" and collectively, the
"Borrowers"), HEREBY JOINTLY AND SEVERALLY PROMISE TO PAY to the order of BANK
OF AMERICA, N.A., a national banking association (the "Lender"), the principal
amount of THIRTEEN MILLION DOLLARS (or such lesser amount as shall have been
advanced and remain outstanding hereunder) on August 14, 2002 (the "Maturity
Date").

     1.   Interest. The Borrowers further, jointly and severally, promise to pay
          --------
interest on the unpaid principal amount of the indebtedness evidenced hereby
from the date advanced until such principal amount is paid in full at a per
annum rate of interest equal to The Wall Street Journal LIBOR Rate plus two
percent (2%). "The Wall Street Journal LIBOR Rate" is the fluctuating rate of
interest equal to the one-month London Interbank Offered Rate as published in
the "Money Rates" section of The Wall Street Journal on the immediately
                             -----------------------
preceding Business Day (as hereinafter defined), as adjusted from time to time
in the Lender's sole discretion for then applicable reserve requirements,
deposit insurance assessment rates and other regulatory costs. Interest will
accrue on any non-Business Day at the rate in effect on the immediately
preceding Business Day. Accrued interest shall be payable, in arrears, on the
first day of each calendar month (for the immediately preceding calendar month)
commencing on the first such day following the date hereof and, if not
theretofore paid in full, on the Maturity Date. Notwithstanding the foregoing,
effective immediately upon the occurrence of an Event of Default (as such term
is defined below), and for as long thereafter as such Event of Default shall be
continuing unwaived, the principal balance outstanding hereunder, shall bear
interest at eighteen percent (18%) per annum. Interest at the rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder).
Notwithstanding any provision of this Note, the Lender does not intend to charge
and the Borrowers shall not be required to pay any amount of interest or other
charges in excess of the maximum permitted by applicable law. The Borrowers,
jointly and severally, agree that during the full term hereof, the maximum
lawful interest rate for this Note as determined under Texas law shall be the
indicated rate ceiling as specified in Article 5069-1.04 of Vernon's Annotated
Texas Statutes. Further, to the extent that any other lawful rate ceiling
exceeds the rate ceiling so determined then the higher rate ceiling shall apply.
Any payment in excess of such
<PAGE>

maximum shall be refunded to Borrower or credited against principal, at the
option of the Lender.

     2.   Use of Proceeds. The Borrowers further, jointly and severally, agree
          ---------------
and covenant that proceeds of the loan advanced under this Note shall be used
(i) first, to make dividends and distributions to Aviation Sales Company to
enable it to pay accrued interest due under the Indenture (as hereinafter
defined), and (ii) second, for working capital and general business purposes.

     3.   Payments. All payments of principal and interest in respect of this
          --------
Note shall be made to the Lender in lawful money of the United States of America
in same day funds on the date due at the Lender's office designated below. Funds
received by the Lender as aforesaid no later than 4:00 p.m. (Houston time) on
any given Business Day shall be credited against payment to be made that day and
funds received by the Lender after that time shall be deemed to have been paid
on the next succeeding Business Day. "Business Day" shall mean a day in the
applicable local time which is not a Saturday or Sunday or a legal holiday and
on which banks are not required or permitted by law or other governmental action
to close in Houston, Texas. All payments made on account of principal hereof and
interest thereon shall be recorded by the Lender on its books and records. The
Borrowers have elected to authorize the Lender to effect payment of sums due
under this Note by means of debiting the Borrowers' account number 3661094818 at
Bank of America, N.A.. The Lender will endeavor to advise the Borrower of the
amount of each debit at least two Business Days prior thereto by written or oral
notice (but the failure of the Borrower to receive any such notice shall not
negate the Lender's right to debit such account.) This authorization shall not
affect the obligation of the Borrowers to pay such sums when due, without
notice, if there are insufficient funds in such account to make such payment in
full on the due date thereof, or if the Lender fails to debit the account.

     4.   Subordination Agreement; Indenture. Indebtedness evidenced by this

any of the obligations evidenced by this Note remain unsatisfied, the
obligations of such Borrower under this paragraph shall not be discharged except
by performance and then only to the extent of such performance. The obligations
of each Borrower under this paragraph shall not be diminished or rendered
unenforceable by any winding up, reorganization, arrangement liquidation,
reconstruction or similar proceeding with respect to any Borrower or the Lender.
The joint and several liability of the Borrowers hereunder shall continue in
full force and effect notwithstanding any absorption, merger, amalgamation or
any other change whatsoever in the name, membership, constitution or place of
formation of any Borrower or the Lender. The provisions of this paragraph are
made for the benefit of the Lender and its successors and assigns, and may be
enforced by any such person from time to time against any of the Borrowers as
often as occasion therefor may arise and without requirement on the part of any
such person first to marshal any of its claims or to exercise any of its rights
against any other person or to exhaust any remedies available to it against any
other person or to resort to any other source or means of obtaining payment of
any of the indebtedness evidenced hereto or to elect any other remedy. The
provisions of this paragraph shall remain in effect until all the indebtedness
evidenced hereby shall have been paid in full or otherwise fully satisfied. If
at any time, any payment, or any part thereof, made in respect of any of such
indebtedness, is rescinded or must otherwise be restored or returned by the
Lender upon the insolvency, bankruptcy or reorganization of any of the
Borrowers, or otherwise, the provisions of this paragraph will forthwith be
reinstated in effect, as though such payment had not been made.

     Notwithstanding any provision to the Excess Funding Borrower (as defined
below), each other Borrower shall, on demand of such Excess Funding Borrower
(but subject to the next sentence hereof and to subsection (B) below), pay to
such Excess Funding Borrower an amount equal to such Borrower's Pro Rata Share
(as defined below and determined, for this purpose, without reference to the
properties, assets, liabilities and debts of such Excess Funding Borrower) of
such Excess Payment (as defined below). The payment obligation of any Borrower
to any Excess Funding Borrower under this paragraph shall be subordinate and
subject in right of payment to the prior payment in full
<PAGE>

of the indebtedness of such Borrower under the other provisions of this Note,
and such Excess Funding Borrower shall not exercise any right or remedy with
respect to such excess until payment and satisfaction in full of all of such
obligations. For purposes hereof, (i) "Excess Funding Borrower" shall mean, in
respect of any obligations arising under the other provisions of this Note
(hereafter, the "Joint Obligations"), a Borrower that has paid an amount in
excess of its Pro Rata Share of the Joint Obligations, (ii) "Excess Payment"
shall mean, in respect of any Joint Obligations, the amount paid by an Excess
Funding Borrower in excess of its Pro Rata Share of such Joint Obligations, and
(iii) "Pro Rata Share", for the purposes of this paragraph, shall mean, for any
Borrower, the ratio (expressed as a percentage) of (A) the amount by which the

the obligations of such Borrower hereunder) to (B) the amount by which the
aggregate present fair saleable value of all assets and other properties of such
Borrower and all of the other Borrowers exceeds the amount of all of the debts
and liabilities (including contingent, subordinated, unmatured, matured and
unliquidated liabilities, but excluding the obligations of such Borrower and the
other Borrowers hereunder) of such Borrower and all of the other Borrowers, all
as of the date hereof.
