                                  TERM NOTE III

$2,500,000.00                                                November 22, 2002
                                                         Hartford, 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, Connecticut ("PAYEE") or other holder of
this Note the principal sum of TWO MILLION FIVE HUNDRED THOUSAND AND 00/100
($2,500,000.00) 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 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
200 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 one
month 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 December 22, 2002,
and on the twenty-second (22nd) day of each month thereafter, Maker shall make
payments of interest as set forth herein. Commencing on December 22, 2002, and
on the twenty-second (22nd) day of each month thereafter, for 83 consecutive
months, Maker shall make payments of principal, each in the amount of
$13,888.89, with a final payment on the Maturity Date in the then unpaid
principal balance of this Note (each to be accompanied by a payment of interest
in arrears on the unpaid balance at the interest rates set forth and calculated
on the basis of a year of three hundred and sixty (360) days but for the actual
number of days elapsed).

                                        1

         Maturity Date. The final maturity date of this Note shall be November
22, 2009, on which date the entire outstanding 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.

         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. 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.

                                        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

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.

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.
