                                    --------

         WHEREAS, the Queens and the Company are parties to a Stock Purchase
Agreement dated as of September 16, 1998 (the "Purchase Agreement") (Capitalized
terms used herein and not defined herein shall have the respective meanings set
forth in the Purchase Agreement);

         WHEREAS, on September 30, 1999, the Company sold its security
businesses (the Sale"), pursuant to an agreement with respect to the sale of
stock of the Company's security businesses, which Sale is a Termination Event
pursuant to the Purchase Agreement;

         WHEREAS, a dispute among the parties to the Purchase Agreement exists
as to whether the Queens are entitled to receive stock or cash pursuant to the
Deferred Purchase Price provision of the Purchase Agreement;

         WHEREAS, the parties hereto desire to set forth certain agreements to
settle such dispute and to amend certain agreements set forth in the Purchase
Agreement;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth herein, the parties hereto agree as follows:

         1. DEFERRED PURCHASE PRICE. The Company hereby agrees to pay or deliver
to the Queens the following: (i) on January 11, 2000, or, if later, two business
days following the execution of this Agreement, 1,227,969 shares of Common Stock
of the Company, which number of shares is equal to approximately 19.9% of the
currently outstanding shares of Common Stock of the Company (the "Earn-out
Stock") and (ii) on January 12, 2000 $2,522,031 (the "Earn-out Cash"). The
delivery of the Earn-out Stock and Earn-out Cash by the Company to the Queens
pursuant to this Section 1 shall constitute payment in full of the Deferred
Purchase Price (as defined in the Purchase Agreement) pursuant to Section 2.4 of
the Purchase Agreement, provided that the Earn Out Stock and any Make-Up Stock
which may be issued in the future as a result of sales of Earn Out Stock at less
than its original value shall be considered Response Stock paid at Closing under
the Purchase Agreement including, without limitation, Section 2.6(a) thereof.
One-third of the Earn-out Stock and one-third of the Earn-out Cash shall be
delivered to each of the Queens. Notwithstanding anything to the contrary
contained in the Purchase Agreement, the sale of the Earn-out Stock shall not be
registered with the Securities and Exchange Commission and the Company shall
have no obligation to file a registration statement with respect to the sale of
the Earn-out Stock, except as provided in Section 2(b) below.





         2.       MAKE-UP STOCK; STANDSTILL PERIOD; BOARD OF DIRECTORS.

                  a. Notwithstanding anything to the contrary contained in the
Purchase Agreement, Section 2.6 of the Purchase Agreement is hereby amended such
that July 10, 2000 in lieu of March 31, 2000 shall be the next date for delivery
of Make-Up Stock or payment of cash, at the option of the Company, to the Queens
pursuant to Section 2.6 of the Purchase Agreement from the sale of Response
Stock (excluding any sale of the Earn-out Stock, which shall be restricted from
sale for the Standstill Period pursuant to (b) below) during the period ending
June 30, 2000 (the applicable "Make-Up Date" being changed from March 31, 2000
to June 30, 2000). In addition, on July 10, 2000, the Company shall pay the
Queens, either as Make-Up Stock or in cash, an amount equal in value to the
product of (x) the difference between $4.15 and the average closing bid price
per share of the Common Stock of the Company on the NASDAQ Stock Market during
the fifteen (15) trading days immediately preceding the date the Company
delivers such Make-Up Stock to the Queens, times (y) the number of shares of
Response Stock owned by the Queens prior to the date hereof and still owned by
the Queens as of June 30, 2000. In the event the Common Stock of the Company is
not listed on NASDAQ during any portion of the 15 trading day period prior to
delivery of any Make-Up Stock, the value of such stock shall be determined by
agreement between the Board of Directors of the Company and the Queens, or if
such agreement is not reached within ten days following any Make-Up Date, by a
nationally recognized appraisal firm, without deduction for lack of
marketability or minority interest. In the event that the Company elects to
deliver Make-Up Stock to the Queens on such date, notwithstanding anything to
the contrary contained in the Purchase Agreement, the sale of such Make-Up Stock
shall not be registered with the Securities and Exchange Commission and the
Company shall have no obligation to file a registration statement with respect
to the sale of the Make-Up Stock, except as provided in Section 2(b) below.

                  b. The Queens agree that for the period (the "Standstill
Period") commencing on the date hereof and ending upon the earlier of January
11, 2002 or the occurrence of a Standstill Termination Event, as defined in
EXHIBIT A, the Queens shall not offer, pledge, sell, transfer, assign, contract
to sell, grant any option for the sale of, or otherwise dispose of, directly or
indirectly, either pursuant to Rule 144 of the regulations under the Securities
Act of 1933, or otherwise, (i) any shares of the Earn-out Stock or (ii) any
shares of Make-Up Stock which may be delivered to the Queens pursuant to Section
2(a) above. The foregoing shall include a restriction on sales "against the box"
or other short sales of the Earn-out Stock or any shares of Make-Up Stock. In
addition, notwithstanding the fact that a Termination Event has occurred, the
Queens agree that until July 10, 2000 or, in the event the Company pays the
entire Make-Up payment due July 10, 2000 in cash, until the termination of the
Standstill Period, the shares of Common Stock of the Company owned by them prior
to the date hereof shall be subject to the restriction set forth in the first
two sentences of this Section 2(b). If the Company pays any of such Make-Up
payment by delivery of Make-Up Stock, the limitation set forth in Section 5.11
of the Purchase Agreement, modified to permit the sale by the Queens of not more
than an aggregate of 10,000 shares of Common Stock per day in open market
transactions shall be in effect until the termination of the Standstill Period.
Upon termination of the Standstill Period, the common stock of the Company
issued as Earn-Out Stock and Make-Up Stock, if any, shall be registered


                                     - 2 -





pursuant to Section 5.10(k) of the Purchase Agreement as if such shares were
issued on the date of such termination.

                  c. Pursuant to Section 2.6 (b) of the Purchase Agreement, the
Queens are currently entitled to designate one member of the Board of Directors
of the Company, which right has not currently been exercised by the Queens but
is available for exercise. The Company agrees that in the event the Company
elects to deliver any shares of Make-Up Stock in lieu of cash to the Queens on
July 10, 1999 pursuant to Section 2.6 of the Purchase Agreement as amended
hereby, the Queens shall be entitled to designate an additional two members of
the Board of Directors of the Company (constituting a then total of three
designees); provided, however, that the number of members of the Board following
such designation by the Queens shall then consist of not more than seven (7)
members (one of whom shall be Richard M. Brooks) until the termination of the
Standstill Period, and provided, further, that the number of directors of the
Company from the date hereof until receipt of the Make-Up Payment due July 10,
2000, shall not exceed five (5) (one of whom shall be Richard M. Brooks).

         3.       NON-COMPETITION AND NONDISCLOSURE AGREEMENT. The Queens
acknowledge that no event pursuant to Section 11 of (i) that certain
Non-Competition and Disclosure Agreement between the Company and Jeffrey Queen
dated as of October 1, 1998 or (ii) that certain Non-Competition and Disclosure
Agreement between the Company and Andrew Queen dated as of October 1, 1998 has
occurred and such agreements remain in full force and effect.

         4.       COMPANY'S REPRESENTATIONS, WARRANTIES AND COVENANTS. The
Company represents, warrants and covenants to the Queens as follows:

                  a. The execution, delivery and performance of this Agreement
by the Company and the transactions contemplated hereby, (i) have been
authorized by all necessary actions on the part of the Company, (ii) will not
violate any provision of the Articles of Incorporation or Bylaws of the Company,
(iii) will not violate or conflict with or constitute a default (or an event

nor result in the termination of, or accelerate the performance required by, nor
result in the creation of any lien, security interest, change or encumbrance
upon any of the Company's or its affiliates' assets under any term or provision
of any contract, commitment, understanding, arrangement, agreement or
restriction of any kind or character to which it is a party or by which it or
any of its assets are bound or affected, and (iv) will not violate or be in
conflict with any law, rule or regulation, or any judgment, decree, injunction
or order applicable to the Company or its affiliates. This Agreement constitutes
the legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, except as may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to or affecting
creditors' rights generally.

                  b. No authorization, consent, approval, order of or filing
with or notice to any governmental agency, instrumentality or authority or any
other person is necessary for the execution and delivery of this Agreement by
the Company or the performance by the Company of its obligations hereunder. In
the event that the Company shall desire to issue Make-Up Stock


                                     - 3 -





with respect to the June 30, 2000 Make-Up Date and outside counsel for the
Company shall advise that the Company's common stock would be delisted from
NASDAQ unless shareholder approval of such issuance or a waiver of any
requirement for such shareholder approval is obtained from NASDAQ, the Company
shall either obtain such approval or waiver prior to July 10, 2000 or the
Make-Up Payment due on such date will be paid entirely in cash.

                  c. The capitalization of the Company is set forth in EXHIBIT
B. All shares of common stock of the Company included in the Earn-Out Stock and
any Make-Up Stock upon receipt by each of the Queens will be duly issued and
outstanding and fully paid and nonassessable, issued in the name of the
applicable Queen.

                  d. All financial statements and other information the Company
has filed with the SEC in the 24-month period preceding the date hereof were at
the time of filing true and complete in all material respects and did not
contain any untrue statements of material fact or omit to state a material fact
necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading.

                  e. During the period commencing on the date hereof and ending
on the date the Company shall make payment in full of the Make-Up Payment due
July 10, 2000 (the "Interim Period"), the Company shall not without the prior
written approval of the Queens (i) issue or agree to issue any common stock or
options or warrants or similar rights to acquire common stock, or any other

contractual obligations previously entered into by the Company which are
described in footnote 7 of the quarterly financial statements included in the
Company's Form 10QSB for the quarter ending September 30, 1999, or, (ii) reprice
or enter into any agreement to reprice or amend any material provisions of any
stock option or other employee benefit plan of the Company.

                  f. During the Interim Period, neither the Company nor its
affiliates shall, directly or indirectly, (i) purchase or agree to purchase any
Company common stock, preferred stock or any other securities, or, (ii) during
the thirty (30) day period preceding the delivery of any Make-Up Stock,
encourage or solicit other persons to purchase common stock of the Company,
provided that customary press releases, SEC filings and investor relation
activities shall be permitted during such thirty (30) day period.

                  g. During the Interim Period the Company shall not cause,
suffer or permit a Standstill Event to occur.
