                           REPLACEMENT TERM LOAN NOTE

$5,000,000                                                         July 12, 2002

         FOR VALUE RECEIVED, the undersigned, AEROCELL STRUCTURES, INC., an
Arkansas corporation, TRIAD INTERNATIONAL MAINTENANCE CORPORATION, a Delaware
corporation, AIRCRAFT INTERIOR DESIGN, INC., a Florida 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 FIVE MILLION DOLLARS (or such lesser amount as shall have
been advanced and remain outstanding hereunder) on the earlier to occur of (a)
January 31, 2004 (or if not a Business Day (defined below), the next preceding
Business Day)), and (b) the date of termination of the Revolving Credit
Commitments (as defined in the Credit Agreement (defined below) under the Credit
Agreement (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 weekly ceiling as specified in Chapter 303 of the Texas Finance Code,
as amended. 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 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 the Existing Note (defined
in Section 26 hereof) that this Note replaces in part were used (i) first, to
make dividends and distributions to Timco Aviation

<PAGE>

Services, Inc., a Delaware corporation, to enable it to pay accrued interest due
under the SunTrust 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
Note shall constitute "Senior Debt" of each Borrower as defined in (i) that

Central Florida, National Association as supplemented by that Supplemental

predecessors-in-interest of any environmental, health or safety requirements of
law, the past, present or future operations of any Borrower, any Affiliate
Guarantor or their respective predecessors-in-interest, or the past, present or
future environmental, health or safety condition of any respective past, present
or future property of such persons, the presence of asbestos-containing
materials at any respective past, present or future property of such persons, or
the release or threatened release of any contaminant into the environment by any
Borrower, any Affiliate Guarantor or their respective predecessors-in-interest,
or the release or threatened release of any contaminant into the environment
from or at any facility to which any Borrower, any Affiliate Guarantor or their
respective predecessors-in-interest sent or directly arranged the transport of
any contaminant (collectively, the "Indemnified Matters"), provided, however,
the Borrowers shall have no obligation to an Indemnitee hereunder with respect
to Indemnified Matters caused by or resulting from the "willful misconduct" or
"gross negligence" of such Indemnitee, as determined by a final, nonappealable
order of a court of competent jurisdiction and (b) not to assert any claim

or satisfaction of any term, covenant, condition or provision of this Note, any
and all other indulgences whatsoever by the Lender in respect of any of such
obligations, and the taking, addition, substitution or release, in whole or in
part, at any time or times, of any security for any of such obligations or the
addition, substitution or release, in whole or in part, of any Borrower. Without
limiting the generality of the foregoing, each Borrower assents to any other
action or delay in acting or failure to act on the part of the Lender,
including, without limitation, any failure strictly or diligently to assert any
right or to pursue any remedy or to comply fully with the

                                       9

<PAGE>

applicable laws or regulations thereunder which might, but for the provisions of
this paragraph, afford grounds for terminating, discharging or relieving such
Borrower, in whole or in part, from any of its obligations hereunder, it being
the intention of each Borrower that, so long as 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 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 aggregate
present fair saleable value of all of its assets and properties exceeds the
amount of all debts and liabilities of such Borrower (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding 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,

                                       10

<PAGE>

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.

                      SECOND AMENDMENT TO LIMITED GUARANTY

                               As of July 12, 2002

Bank of America, N.A.
Private Bank
700 Louisiana, 6/th/ Floor
Houston, Texas 77002
Attn: Samantha Kennedy

         Re:    Limited Guaranty

Ladies and Gentlemen:

         Reference is made to that certain Limited Guaranty dated as of February
14, 2001 (the "Guaranty) executed by LJH, LTD., a Texas limited partnership
("Guarantor") in favor of BANK OF AMERICA, N.A., a national banking association
(the "Lender"), as amended by that certain First Amendment to Limited Guaranty
dated as of May 24, 2001, executed by Guarantor in favor of Lender. Unless
otherwise indicated, all capitalized terms herein are used as defined in the
Guaranty, as amended.

         For good and valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Guarantor and Lender agree as follows:

         1.     Certain Definitions.  As used in the Guaranty, as amended, the
following term hereafter has the amended meaning indicated as follows:

                "Term Note" shall mean that certain Replacement Term Loan Note
         dated as of July 12, 2002, in the principal amount of $5,000,000 and
         executed by AEROCELL STRUCTURES, INC., an Arkansas corporation, TRIAD
         INTERNATIONAL MAINTENANCE CORPORATION, a Delaware corporation, AIRCRAFT
         INTERIOR DESIGN, INC., a Florida corporation, and TIMCO ENGINE CENTER,
         INC., a Delaware corporation, and payable to the order of Lender (as
         further amended, modified, restated or replaced from time to time).

         2.     Other Amendments.  Section 1(i) of the Guaranty, as amended, is
hereby amended and restated to read in its entirety as follows:

         For value received and in consideration of any loan, advance or
         financial accommodation of any kind whatsoever heretofore, now or
         hereafter made, given or granted to the Borrowers by the Lender under
         the Term Note, the Guarantor unconditionally guarantees the full and
         prompt payment when due, whether at maturity or earlier, by reason of
         acceleration or otherwise, and at all times thereafter, 50% of the
         indebtedness evidenced by the Term Note (such guaranteed portion being
         referred to herein as the "Obligations") (including, without
         limitation, interest accruing following the filing of a bankruptcy
         petition by or against any Borrower, at the applicable rate specified
         in the Term Note, whether or not such interest is allowed or allowable
         as a claim in bankruptcy, but

<PAGE>

         excluding any increase in the principal amount of the Term Note,
         whether by amendment or otherwise, which is not consented to in writing
         by the Guarantor).

         3.     Guaranty; Effect.  Except as amended in this instrument, the
Guaranty is and shall be unchanged and shall remain in full force and effect.

         4.     Multiple Counterparts. This instrument may be executed in more
than one counterpart, each of which shall be deemed an original, and all of
which constitute, collectively, one instrument; but, in making proof of this
instrument, it shall not be necessary to produce or account for more than one
such counterpart. It shall not be necessary for Guarantor and Lender to execute
the same counterpart hereof so long as Guarantor and Lender execute a
counterpart hereof.

         5. Final Agreement. The Guaranty, as Amended Hereby, Represents the
Final Agreement Between the Parties and May Not Be Contradicted by Evidence of
Prior, Contemporaneous or Subsequent Oral Agreements of the Parties. There Are
No Oral Agreements Between the Parties.

         If the foregoing terms and conditions are acceptable to Guarantor,
Guarantor should indicate its acceptance by signing in the space provided below,
whereupon this letter shall become an agreement binding upon and inuring to the
benefit of Lender and Guarantor and their respective successors and assigns.

                                    Very truly yours,

                                    LJH LTD., a Texas limited partnership
