Dear Mr. Flagg:

        We are pleased to advise you that, subject to the terms and conditions
set forth herein, Bank of Boston Connecticut (the "Bank") has committed to
participate in the $25,000,000 credit facility (the "Credit Facility") to be
provided by Merita Bank acting through its New York branch ("Merita") to Holmes
Protection Group, Inc. (the "Borrower"). This letter sets forth the terms and
conditions on which the Bank is willing to participate in the Credit Facility.

        1. STRUCTURE. The Bank shall participate in the Credit Facility as a
direct lender to Borrower.

        2. COMMITMENT AMOUNT. The Bank shall participate in the Credit Facility
in the principal amount of $10,000,000 (the "Commitment Amount"); provided,
however, that the Bank shall have no obligation to advance more than $5,000,000
until the Borrower successfully completes a sale of capital stock resulting in
net proceeds of at least $10,000,000 to the Borrower (which sale must be
completed on or before October 31, 1996).

        3. COMMITMENT PERCENTAGE. The Bank's percentage of the aggregate
commitments of all lenders participating in the Credit Facility shall be 40%
(the "Commitment Percentage").

        4. PAYMENTS OF PRINCIPAL. The Bank shall share in any payments or
principal, including prepayments, made or required to be made by the Borrower
under the Credit Facility in accordance with its Commitment Percentage.

        7. COLLATERAL. The Bank shall share in (i) any collateral now or
hereafter provided by the Borrower to secure the payment and performance of its
obligations under the Credit Facility, (ii) any guarantees now or hereafter

Facility and (iii) any collateral now or hereafter provided to secure any of
