Mr. Tom Few Sr.
Mr. Tim McGinn

325 S. River Street
Hackensack, New Jersey

Gentlemen:

On behalf of QOMLINQ, Dana Harbor Insurance Service and ACE USA / Westchester
Specialty Services, we would like to express our appreciation for your interest
in our Insured Extended Warranty ("IEW") Program for alarm systems.

We have enjoyed our association with McGinn, Smith & Company over the years, and
we look forward to a new and mutually profitable relationship with King Central.

This Letter Agreement is designed to cover special considerations granted by
QOMLINQ to King Central as it relates to (1) the assistance of King Central in
the marketing and distribution of the IEW to alarm dealers that are currently
utilizing King Central for (a) alarm monitoring services and/or (b) are selling
or financing alarm contracts under a King Central dealer program, and (2) the
purchase of IEW coverage for accounts owned by King Central or any third party
entity in which King Central or its principals are equity holders. (The terms
and conditions relating to items (1) and (2) above are set forth separately
below.)

1.  MARKETING AND DISTRIBUTION OF IEW:

        A.  King Central has relationships with approximately 4,000 security
            alarm dealers ("King Dealers"). It is the desire of QOMLINQ and King
            Central to make the IEW Program available to King Dealers through
            the marketing efforts of King Central on behalf of QOMLINQ.

        B.  King Central is a wholesale monitoring company providing monitoring
            services to independent alarm dealers. During the term of this
            Agreement it is the desire of King Central that they have the
            exclusive right to be the only wholesale monitoring company with the
            right to market the IEW to independent alarm dealers. QOMLINQ hereby
            grants to King Central the right to be the only wholesale monitoring
            company with the right to market the IEW Program to independent
            alarm dealers for the period of one year, beginning July 1, 2001,
            subject to minimum production requirements equal to a total of 2000
            individual IEW issued by the end of the first quarter and 4,000
            written individual IEW per month thereafter. In the event the
            minimum production requirement is not attained, all terms and
            conditions of this Agreement shall remain in effect with the
            exception of the exclusive right, which shall


                                     QOMLINQ

            become non-exclusive. Nothing contained herein shall preclude
            QOMLINQ from marketing or distributing IEW, during any exclusive or
            non-exclusive periods of this Agreement, directly or through any
            other source with the exception of wholesale monitoring companies as
            describe above.

        C.  King Central may private label the IEW as the King Central Insured
            Extended Warranty Program for alarm systems.

        D.  The following modifications have been made to the IEW as follows,
            all of which shall be included within the terms and conditions of
            this Agreement.

            1.  The labor reimbursement rate to King Dealers shall be increased
                to $65 per hour from the original $50 per hour. The maximum of
                $100 labor per claim shall remain unchanged. Parts shall
                continue to be reimbursed at dealer cost, pius 25%.

            2.  The dealer cost for the IEW shall be:
                (a) One Year IEW = $50.00
                (b) Two Year IEW = $65.00
                (c) Three Year IEW= $80.00
                (d) Dealers may mark up items (a) thru (c) above, not to exceed
                    twice the dealer cost.


        E.  King Central shall receive a marketing commission equal to $8.00 per
            IEW sold. Dealers shall remit IEW funds payable to King Central.
            King Central will remit Net IEW funds to Dana Harbor, less the King
            Central $8.00 marketing commission. King Central shall be entitled
            to the marketing commission set forth herein for as long as any King
            Dealer continues to utilize the IEW Program irrespective of whether
            this Agreement remains in force.

        F.  To assist King Central in its marketing and distribution efforts of
            the IEW;

            1.  ACE USA shall provide King Central with
                "Potential-Promise-Product-Profit" empty folder jackets to
                insert King Central produced marketing materials.

            2.  QOMLINQ shall provide 3.5 Floppy Disks containing all applicable
                IEW dealer documents for use by King Dealers who have enrolled
                in the IEW Program. QOMLINQ shall deliver the disks in 100
                quantities, as needed.

        G.  QOMLINQ acknowledges that the identity of King Dealers is
            confidential and shall not disclose the names of any King Dealer to
            any other party with the exception of Dana Harbor Insurance and ACE
            USA.

        H.  King Central and QOMLINQ mutually acknowledge that the coverage,
            rates and terms and conditions of the IEW may be modified by ACE USA
            in their sole discretion.

            King Central or third party entities in which it has an equity
            interest, covering owned alarm contracts.
