which at all times is equal to the Prime Rate, said rate to change when and as

<PAGE>
                                    (ii) At the election of Borrower made
pursuant to a Notice of Interest Rate Election (in form and substance as set

of principal. Interest on all Loans shall be computed using a per diem rate
which shall be a fraction, the numerator of which shall be the rate of interest
calculated in accordance with Section 1.5(A) or (B) above and the denominator of
which shall be three hundred sixty (360), multiplied by the actual number of
days elapsed. For the purposes of computing interest earned on the Loans,
including without limitation interest payments which are paid by an Advance (in
which case such advance shall constitute a Loan) or interest payments which are
withdrawn directly from Borrowers' accounts maintained with Lender or are made
by other current funds (AND EACH BORROWER HEREBY CONSENTS TO ANY AND ALL SUCH
ADVANCES AND/OR WITHDRAWALS, AND/OR PAYMENTS BY ANY OTHER MEANS AVAILED OF BY
LENDER, AND FURTHER CONSENTS TO PAYMENTS OF PRINCIPAL AND/OR INTEREST ON ANY OF
THE LOANS AND/OR OTHER SUM OWING TO LENDER BY SUCH ADVANCES AND/OR WITHDRAWALS),
credit for checks deposited, wire transfers received or payment by any other
means shall be given on the third (3rd) business day following the receipt of
such check, wire transfer or other form of payment. In the event any payment of
principal and/or interest shall be returned unpaid for any reason, any credit
given on account of such payment shall be deleted, interest shall accrue
retroactively to the date such credit was given and such payment shall be deemed
for all purposes under this Agreement, never to have been made. Any interest not
paid as aforesaid may, in Lender's sole discretion, accrue and be added to the
principal and continue to bear interest at the rate being borne by such
principal

                  1.7 Prepayment. Any amounts outstanding bearing interest at
the LIBOR Rate may only be prepaid if any such prepayment is accompanied by the
Prepayment Premium.

         SECTION 6. SET-OFF RIGHTS.

and not by way of limitation of any such rights, each Lender and any affiliate
of Lender is hereby authorized by Borrower and the Guarantor at any time or from
time to time, without notice to Borrower or to any other Person, any such notice
being hereby expressly waived by Borrower and Guarantor to set off and to
appropriate and to apply any and all balances, deposits, credits, Collateral and
property of Borrower held at, or in transit to, any of its offices for the
account of Borrower and/or Guarantor (regardless of whether then due to Borrower
and/or Guarantor) and any other property at any time held or in transit or owing
by that Lender or that holder to or for the credit or for the account of
Borrower or Guarantor against and on account of any of the Loans which remain
unpaid. Borrower and Guarantor agree, to the fullest extent permitted by law,
that (a) Lender or any holder may exercise its right to set off with respect to
the Loans and may sell participations in such set off to other lenders and
holders and (b) any lender or holder so purchasing a participation in the Loans
made or held by other lenders or holders may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender or holder were a direct holder of Loans in the amount
of such participation and (3) the rights contained in this paragraph exist
regardless of whether the Loan to which they are applied has matured.

         SECTION 7.  REMEDIES ON DEFAULT, ETC.

                  7.1 If a Default or Event of Default occurs, Lender may

its rights by suit in equity, action at law or other appropriate proceedings,
whether for the specific performance of any agreement contained herein or in any
other Document, or for an injunction against a violation of any of the terms
hereof or thereof, or in aid of the exercise of any right, power or remedy
granted thereby or by law, equity or otherwise.

                  7.2 Upon the occurrence of a Default or Event of Default the
Borrower grants a royalty-free license to the Lender for all patents, service
marks, trademarks, tradenames, copyrights, computer programs and other
intellectual property rights sufficient to permit the Lender to exercise all
rights granted to the Lender pursuant to this Agreement.

         SECTION 8.  CUMULATIVE REMEDIES; NO WAIVERS, ETC.

         No right, power or remedy granted to Lender in this Agreement or in the

addition to any other rights, powers

                                       24
<PAGE>
or remedies referred to in this Agreement, in the other Documents or otherwise
available to Lender at law or in equity; and the exercise or beginning of
exercise by Lender of any one or more of such rights, powers or remedies, shall
not preclude the simultaneous or later exercise by Lender of any or all of such
other rights, powers or remedies. No waiver by, nor any failure or delay on the
part of Lender in any one or more instances to insist upon strict performance or
observance of one or more covenants or conditions hereof, or of the other
Documents shall in any way be, or be construed to be, a waiver of such covenant
in any other instance or to prevent Lender's rights to later require the strict
performance or observance of such covenants or conditions, or otherwise
prejudice Lender's rights, powers or remedies.

         SECTION 9.  PARTIAL INVALIDITY; WAIVERS.

                  9.1 If any term or provision of this Agreement or any of the
other Documents or the application thereof to any Person or circumstance shall,
to any extent, be invalid or unenforceable by reason of any applicable law, the
remainder of this Agreement and the other Documents, or application of such term
or provision to Persons or circumstances other than those as to which it is held
invalid or unenforceable, shall not be affected thereby, and each term and
provision of this Agreement and the other Documents shall be valid and be
enforced to the fullest extent permitted by law. To the full extent, however,
that the provisions of any such applicable law may be waived, they are hereby
waived by Borrower to the end that this Agreement and the other Documents shall
be deemed to be valid and binding obligations enforceable in accordance with
their terms.

                  9.2 To the extent permitted by applicable law, Borrower and
Guarantor hereby waives protest, prior notice of protest, or dishonor, notice of
payments and non-payments, or of any default.

                  9.3 WITH RESPECT TO ANY CONTROVERSY, ACTION, PROCEEDING OR

REPOSSESSION OR SELF HELP AS MAY PRESENTLY EXIST UNDER STATUTE OR COMMON LAW.

                  9.5 BORROWER SPECIFICALLY WAIVES AND RELINQUISHES ANY CLAIM TO
INCIDENTAL AND/OR CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF AN ALLEGED

applicable amounts) are not being offered to banks in the interbank Eurodollar
market for the selected Interest Period, or (b) that the LIBOR Rate does not
accurately reflect the cost to Lender of making or maintaining LIBOR Advances
for the Interest Period or therefor, then Lender shall forthwith give notice
thereof to Borrower, whereupon, (1) the obligation of Lender to permit the LIBOR
Advances to bear interest at the LIBOR Rate shall be suspended so long as such
circumstances exist, and (2) Borrower shall convert the interest rates on the
applicable portions of the outstanding Advances to the rate in relation to the
PRIME RATE set forth above for the current Interest Period. Such suspension
shall continue until Lender notifies Borrower that the circumstances giving rise
to such suspension no longer exist.

                  (ii) If, after the date of this Agreement, the adoption of or
any change in rules, or change in the interpretation or administration thereof,
by a governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for Lender to make or maintain or fund LIBOR Advances, the interest
rates on the applicable portions of the outstanding LIBOR Advances shall be
deemed to have been converted to the rate relating to the PRIME RATE set forth
above, on either (a) the last day of the then current Interest Period if Lender
may lawfully continue to maintain loans at the LIBOR Interest Rate to such day,
or (b) immediately if Lender may not lawfully continue to maintain Advances at
the LIBOR Interest Rate.

                  (iii) Upon notice to Borrower, the Borrower shall pay to the
Lender for the account of Lender, such amount or amounts as shall be sufficient
(in the reasonable opinion of Lender) to compensate it for any loss, cost,
liability or expense incurred as a result of (x) any repayment of a LIBOR
Advance on a date other than the last day of the Interest Period for such LIBOR
Advance, including, but not limited to that resulting from acceleration of all
amounts outstanding under any Loan following the occurrence of any Default or
Event of Default and/or (y) any failure by Borrower to borrow or convert or
prepay, as the case may be, a LIBOR Advance on the date for borrowing or
conversion or prepayment, as the case may be, which is specified in the Notice
of Interest Rate Election.

         NOTICE OF INTEREST RATE ELECTION: Whenever Borrower desires to elect,

Election in form provided by Lender and substance as that attached hereto as

nearest in expiration of the relevant Interest Period. The maturity date and
yield to maturity of such United States Treasury obligation shall be determined
by Lender on the basis of quotations appearing in the Reuter Monitor Money Rates
Service or other repository service reasonably satisfactory to Lender on the
prepayment date. If there shall be more than one such debt obligation of the
United States Treasury maturing nearest in time to the expiration of the
relevant Interest Period, the Prepayment Yield to Maturity shall be the
arithmetic average of the yields to maturity of all such obligations. Said
prepayment shall be irrevocable once Borrower has notified Lender of such
prepayment and Borrower will reimburse Lender for any and all loss, cost,

                                                        New Britain, Connecticut

         FOR VALUE RECEIVED, ACMAT CORPORATION, a Connecticut corporation with a
place of business in New Britain, Connecticut ("Maker"), promises to pay to the
order of WEBSTER BANK, a federally chartered savings bank having a place of
business in Waterbury, Connecticut ("Payee") or other holder of this Note the
principal sum of FIVE MILLION ($5,000,000.00) DOLLARS, together with interest on
the outstanding balance hereof before and after maturity, at the rate
hereinafter set forth until this Note shall have been fully paid, all as
hereinafter provided.

         Interest Rate. The outstanding balance hereof shall bear interest at a
rate per annum (the "Rate") which is at all times equal to the Prime Rate. The
Prime Rate is an annual rate of interest announced from time to time by Payee as
its Prime Rate; it is not necessarily the Payee's lowest or most favorable rate.
The interest rate hereunder shall change simultaneously with each change in the
Payee's Prime Rate without notice or demand of any kind.

         LIBOR Option. At any time after the date hereof, provided no default
hereunder shall have occurred, the Maker may elect, pursuant to a Notice of
Interest Rate Election (as defined in the Agreement hereinafter referenced) to
have amounts outstanding hereunder bear interest at a rate per annum equal to
one hundred ninety (190) basis points per annum in excess of the LIBOR Rate (as
defined in the Agreement) for an Interest Period (as defined in the Agreement)
equal to three months elected by Maker. No election may be made for a period
that extends beyond the maturity date of this Note.

         Amounts outstanding hereunder shall bear interest at the Prime Rate
unless otherwise so elected by Maker.

         Payments of Principal and Interest. Commencing on March 1, 2002, and on
the first day of each June, September, December and March thereafter, Maker
shall make payments of interest as set forth herein. Commencing on March 1,
2004, and on the first day of each June, September, December and March
thereafter, Maker shall make payments of principal, each in the amount of
$250,000.00 (each to be accompanied by a payment of interest in arrears on the
unpaid balance at the Rate(s) aforesaid applicable during the prior three month
period, calculated on the basis of a year of three hundred and sixty (360) days
but for the actual number of days elapsed).

         Maturity Date. The final maturity date of this Note shall be December
1, 2008, on which date the entire indebtedness evidenced by this Note, including
without limitation, the unpaid principal balance and unpaid interest accrued
thereon, shall be due and payable without notice or demand.

                                       1
<PAGE>
         Prepayment. Amounts outstanding hereunder may only be prepaid if such
prepayment is accompanied by the Prepayment Premium as more particularly set
forth in the Agreement.

         Late Payments. In the event that any payment of principal or interest
due hereunder is not received by Payee within five (5) days after the same is
due, then the Maker agrees to pay to the Payee the additional sum of five (5%)
percent of the amount of such late payment to cover the additional expense of
Payee's handling of such late payment (but not as consideration for making such
late payment). Maker and Payee hereby agree that an exact computation of Payee's
damages relating to such late payment is impossible to ascertain, and further
agree that the percentage stated above is a reasonable estimation of Payee's
damages. Such estimation is based upon, inter alia, Payee's additional expenses
relating to (i) sending late notices, (ii) referring the matter to Payee's
collection department and (iii) providing for any necessary regulatory
compliance and reserve requirements.

         Application of Payments. All payments hereon shall be applied to
expenses as provided herein, interest and principal in such order as Payee
shall, in its discretion, determine. Said sums shall be payable together with
all lawful taxes and assessments levied thereon, or upon this Note, or upon the
Payee with respect to the same, and together with all costs and expenses related
to collecting this Note and together with all costs and expenses of foreclosing
or protecting or sustaining the lien of any security which may be given to
secure the payment of this Note, and/or in any litigation or controversy arising
from or connected with this Note and/or any collateral securing this Note and/or
the Agreement hereinafter referred to and/or incurred in any action brought by
the holder of a prior lien in which the Payee is a party defendant, including
without limitation reasonable attorneys' fees. Said obligation to pay the
reasonable attorneys' fees of the Payee in connection with protecting, enforcing
or realizing of the rights and remedies above described shall exist whether or
not proceedings are instituted or court appearance is made on behalf of the
Payee.

         Set Off. Upon the occurrence of an Event of Default the Payee shall
have and may exercise a right of set-off for the payment of this Note and the
aforesaid costs and expenses against, and Maker hereby gives and grants to Payee
a security interest (perfected by Payee's possession thereof) in, all deposits,
monies, securities and property left with the Payee and/or any affiliate of the
Payee by the Maker or by any guarantor, endorser or otherwise to the credit of
or belonging to the Maker or any such party, and the Payee shall have full power
and authority at any time and without prior notice to sell, assign and deliver
any such property at public or private sale, and apply the proceeds in
satisfaction hereof.

         Commercial Credit Agreement. This Note is issued under and pursuant to
the terms of a Commercial Credit Agreement of even date (the "Agreement") by and
among the Maker, the Payee and ACSTAR Holdings, Inc., a Delaware corporation, as
Guarantor, which Agreement is in the possession of the Payee.

         Guarantee. Additionally, payment of this Note is guaranteed pursuant to
a Guaranty Agreement of even date executed and delivered by ACSTAR Holdings,
Inc.

                                       2

         Default. Upon the occurrence of any Event of Default, as such term is
defined in the Agreement or if any payment specified herein shall remain in
arrears and unpaid for a period of ten (10) days after the same shall become
due, at the option of Payee, (i) the interest rate accruing hereunder shall,
from such default, be increased by five (5) percentage points per annum above
the Prime Rate (the "Default Rate") and (ii) this Note shall become forthwith
due and payable without presentment, demand, protest or notice of any kind, all
of which being hereby expressly waived by the undersigned. Without in any way
limiting the generality of the foregoing the interest rate accruing hereunder
shall be the Default Rate (i) upon the option of Payee and (ii) only during the
period when Payee is not also collecting a late payment charge hereunder. Maker
and Payee hereby agree that any Event of Default or default in any payments of
principal or interest hereunder results in, inter alia, additional
administrative costs, regulatory costs, reserve requirements, and credit costs
to Payee. Maker and Payee further agree that such Default Rate approximates the
interest rate Payee might charge to borrowers with sub-standard credit. In the
event the Default Rate exceeds the maximum rate of interest allowed by law, the
Default Rate shall be reduced so as to equal the maximum rate of interest
allowed by law.

         Reimbursement for Costs. If the Payee shall deem applicable to this
Note (including, in each case, the borrowed and the unused portion thereof, if
any) any requirement of any law of the United States of America, any regulation,
order, interpretation, ruling, official directive or guideline (whether or not
having the force of law) of the Board of Governors of the Federal Reserve
System, the Comptroller of the Currency, the Federal Deposit Insurance
Corporation or any other board or governmental or administrative agency of the
United States of America which shall impose, increase, modify or make applicable
to this Note or cause this Note to be included in, any reserve, special deposit,
calculation used in the computation of regulatory capital standards, assessment
or other requirement which imposes on the Payee any cost that is attributable to
the maintenance thereof, then, and in each such event, the Maker shall promptly
pay the Payee, upon its demand, such amount as will compensate the Payee for any
such cost. In the event any such cost is a continuing cost, a fee payable to the
Payee may be imposed upon the Maker periodically for so long as any such cost is
deemed applicable by the Payee, in an amount determined by the Payee to be
necessary to compensate the Payee for any such cost, which determination may be
based upon the Payee's reasonable allocation of the aggregate of such costs
resulting from such events. The determination by the Payee of the existence and
amount of any such costs shall, in the absence of manifest error, be conclusive.

         Successors and Assigns. This Note shall bind the Maker's and the
Maker's successors and assigns and all endorsers hereto and shall inure to the
benefit of Payee and/or any subsequent holder of this Note and/or their
respective successors and assigns.

         Partial Invalidity. In the event that any one or more of the provisions
of this Note shall for any reason be held to be invalid, illegal or
unenforceable, in whole or in part, or in any respect, or in the event that any
one or more of the provisions of this Note shall operate, or would prospectively
operate, to invalidate this Note, then, and in such event, such provision or
provisions only shall be

other provision of this Note, and the remaining provisions of this Note shall
remain in full force and effect, shall be valid, legal and enforceable, and
