                           ASSET PURCHASE AGREEMENT

            THIS ASSET PURCHASE AGREEMENT, dated the ___________ day of
September, 1997, by and between UNITED SECURITY SYSTEMS, INC., a New Jersey
corporation ("Buyer"), RESPONSE USA, INC., a Delaware corporation ("Response"),
and TRIPLE A SECURITY SYSTEMS, INC., a Pennsylvania corporation ("Seller") and
ROBERT L. MAY, an individual ("Shareholder") (as it may be amended or
supplemented from time to time, this "Agreement"). Buyer, Seller and Shareholder
are sometimes individually called a "Party" and collectively called the
"Parties".

                              B A C K G R O U N D:

            Shareholder is the sole shareholder of the Seller. Seller is
engaged, inter alia, in the business of the sale, installation, service,
inspection, testing and monitoring of fire, intrusion and other detection alarm
security devices and systems for customers (the "Business").

            Buyer desires to acquire substantially all of the assets of Seller
(the "Assets") and Seller desires to sell such Assets to Buyer, all upon the
terms and subject to the conditions hereinafter set forth. Response is the
parent company of the Buyer.

            Simultaneously with the execution of this Agreement, Response is
entering into a Stock Purchase Agreement with Robert L. May and Vito Verni for
the Stock of The Jupiter Group, Inc., T/A Triple A Security Patrol (the "Jupiter
Agreement").

            NOW, THEREFORE, in consideration of the mutual agreements and
covenants contained herein and intending to be legally bound, the Parties agree
as follows:

1. Sale and Purchase of Assets.

      1.1 Purchase of Assets. On the Closing Date (as that term is defined in
Section 19.1), subject to and upon the terms and conditions contained herein,
Seller shall sell, transfer, convey, assign and deliver to Buyer and Buyer shall
purchase and acquire from Seller all of Seller's right, title and interest in
and to all of the Assets. The assets being conveyed hereunder (the "Assets")
shall be more particularly described in Exhibit 1.1, and shall include but not
be limited to: all of Seller's assets listed in the Closing Financial Statement
(defined below); all assets owned by, leased or licensed to the Seller, or
otherwise used by the Seller in connection with its business; all of Seller's
alarm monitoring and servicing accounts (the "Alarm Accounts"), all of Seller's
local service accounts (the "Local


                                        1
<PAGE>

Accounts") and all of Seller's sub-contract monitoring accounts (the
"Sub-contract Accounts") with the customers of Seller (the "Customers") all of
Seller's right, title and interest in and to all office equipment, furniture,
fixtures, inventory, computer hardware and software, central station equipment
and telephone system; all of Seller's right, title and interest in any
monitoring equipment, alarm equipment, or other equipment necessary for the
purpose of sending an alarm monitoring signal to a central monitoring station;
all telephone lines owned or leased by Seller and used in connection with the
Alarm Accounts (including any lines into the central station(s) used by Seller
and any lines used for Seller's customer service); all computer software
programs licensed to or used by Seller (including the data base connected
thereto) relating to billing, customer service and/or uploading and downloading
any of the Customer's alarm equipment; all Customer lists (including lists of
any non-monitored accounts installed or serviced by Seller); all licenses and
permits which are required for the conduct of Seller's business; all contracts
and agreements between Seller and the Customers; all Customer files; all
tradenames owned by Seller, including but not limited to "Triple A Security
Systems"; and all of Seller's right, title, and interest in all logos used by
Seller including but not limited to "AAA". Such conveyance shall be confirmed by
a Bill of Sale in the form attached hereto as Exhibit 1.1. Notwithstanding
anything contained in this Section 1.1 to the contrary, the Assets being
conveyed pursuant to this Agreement shall be limited to those that are
assignable by Seller as a matter of right or for which a consent to assignment
is delivered at Closing; provided, however, that in the event that an Asset
which is materially required to operate the Business as a going concern is not
assignable as a matter of right and the Seller is unable to obtain a consent to
assignment, the following provision(s) shall apply:

            1.1.1 Consents. To the extent that the transfer of any of the Assets
to Buyer shall require the consent of any other party or parties thereto, and
such consent shall not have been obtained prior to the Closing Date, the Seller
and Shareholder agree that they will use commercially reasonable efforts to
obtain all consents to the transactions contemplated by this Agreement of any
party to any contract, agreement, arrangement or commitment to which the Seller
is a party or to which the Seller is subject or by which any of its property is
bound and to continue their best efforts after the Closing Date. If any such
consent is not obtained, the Seller and Shareholder agree to cooperate with
Buyer in any reasonable arrangement (such as subcontracting, sublicensing or
subleasing) designed to provide for Buyer the benefits of the Seller under any
applicable contract, agreement, arrangement or commitment, including, without
limitation, enforcement, for the benefit of Buyer, of any and all rights of the
Buyer and against any other party thereto arising out of the breach or
cancellation thereof by such party or otherwise.

      1.2 Excluded Assets. Notwithstanding any provision of this Agreement to
the contrary, there is excluded from the sale and purchase contemplated by this
Section 1 the following assets of Seller (collectively, the "Excluded Assets"),
including:

Response (NASDAQ: RUOK) (the "Current Asset Shares") equal in value to the

____________________________________________________________________________
($___________________________________) based on the lesser of: (i) the average
closing bid price of such Response Shares on the ten (10) trading days prior to

            3.1.5 Buyer has previously furnished to Stockholder (a) the most
recent 10-K Report as filed with the Securities and Exchange Commission (the
"SEC"); (b) all subsequent 10-Q's as filed with the SEC; (c) any subsequent
Reports on Form 8-K as filed with the SEC; (d) definitive proxy statements
relating to all meetings of its stockholders (whether annual or special) since
January 1, 1997; and (e) all other reports and registration statements filed by
Buyer with the SEC since January 1, 1997 (all of the foregoing, the "SEC
Filings"). As of their respective dates, the SEC Filings (including all
documents incorporated by reference therein) did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except, in the case of
any SEC Filing, any statement or omission therein that has been corrected or
otherwise disclosed or updated in a subsequent SEC Filing. Since January 1, 1997
Buyer has timely filed with the SEC all reports, documents, registration
statements, definitive proxy statements and all other filings required to be
filed with the SEC under the rules and regulations of the SEC, and all such
reports, documents, registration statements, definitive proxy statements and
other filings complied in all material respects with all applicable requirements
of the Securities Act of 1933, as amended, and the Securities Exchange Act of
1934, as amended, as applicable.

            3.1.6 Buyer agrees that in the event that any of the Response Shares
are sold by Seller in open market transactions in accordance with the provisions
of Section 3.1.4 above within four (4) years from the Closing Date, and the
average gross sale price per share obtained by Seller is less than the Agreed
Value (as evidenced by copies of appropriate brokerage account statements or any
other manner reasonably acceptable to Buyer) (the "Shortfall Amount"), the Buyer
shall, at its option, either:

                  (a) Pay to the Seller within thirty (30) days after notice of
            such sale an amount equal to the difference between the Agreed Value

made therein, in the context in which made, neither false nor misleading. There
is no fact known by Buyer not disclosed in writing to Seller by Buyer


                                       18

the transactions contemplated by this Agreement.

      5.7 Intentionally Blank.

      5.8 No Actions to Make Representations and Warranties Untrue. Buyer shall

(ii) as necessary to respond to or defend against governmental bodies' requests
for information, audits, claims, administrative agency procedures or lawsuits,
(iii) as necessary to prepare, modify or defend tax returns, (iv) as necessary
to defend lawsuits and other dispute resolution alternatives (including

to assert, pursue or defend rights, duties and obligations under this Agreement
(including access, as necessary, to Information relating to post-Closing Date

Section 5.10, shall be extended for matters pending until such time as the
matter has been finally resolved.

and other terms and conditions of this Agreement,


                                       19
<PAGE>

and not disclose, publish, use or permit others to use the same, except that
Buyer may disclose such terms and conditions with its agents, representatives,
counsel, accountants, officers, directors and others with whom Buyer has a

Buyer, or its employees, agents or representatives, or (b) is rightfully
received from another source on a non-confidential basis, or (c) is released for
disclosure with the consent of Seller, or (d) is required by a court or a

the Buyer shall first notify Seller of such required disclosure and shall take
such steps at Seller's expense as Seller shall reasonably request to limit the
scope of such disclosure and otherwise protect the confidentiality of such
confidential and proprietary information. On and after the Closing Date, the
Confidentiality Agreement between Seller and Buyer dated October 18, 1996 shall
terminate and be of no further force and effect.

(i.e., claims against Seller by the Buyer Indemnified Parties) under Section
7.1. until such amounts exceed One Hundred Thousand Dollars ($100,000), (the
"Deductible") and then only amounts in excess of the Deductible shall be due and
payable. Notwithstanding anything to the contrary contained in this Section
7.3., liabilities for (i) breach of any of the representations and warranties in

shall be waived to the extent of such payment and the other Party shall be
released to the extent of such payment including, without limitation,
subrogation claims, and in the event an insurance company fails or refuses to

entitled to receive its attorneys' fees and other costs and expenses of suit,
(v) third-party claims subject to indemnification shall be reduced by the
proceeds received from each Party's insurance polic(ies) applicable to the claim
for Damages, and (vi) the indemnification obligation of the Seller for any
third-party claims that are not covered by the Seller's insurance policy(ies)
required to be carried after the Closing shall be limited to the Maximum
Indemnity, but the indemnification obligation of the Seller for any third party
claims that are covered by the Seller's insurance policy(ies) required to be

knowledge contained in any of the representations or warranties set forth in
this Agreement shall not limit, reduce or modify Buyer's rights to
indemnification under this Agreement to the extent that such representations or
warranties were not so qualified. Notwithstanding anything contained in this
Sub-section 7.3.3 to the contrary, except for third-party claims, Buyer's right
to indemnification for breach of any Seller or Shareholder representation or
warranty qualified by knowledge shall be limited to fraud or intentional
misrepresentation by Seller or Shareholder.

      7.4 Time Limit on Indemnity.

            7.4.1 Notwithstanding any other provisions of this Section 7, no
claim for indemnification under Section 7.1. or 7.2. shall be made by Buyer
Indemnified Parties or Seller Indemnified Parties (i) with respect to First
Party claims pursuant to Section 7.1. or 7.2. after the first anniversary of the
Closing Date (except that in the case of a breach of Seller's representations
and warranties in Section 4.5. [Taxes], claims of indemnification may be made
until the expiration of the applicable statute of limitations; (ii) with respect
to claims for breach of Seller's covenants in Sections 4.24. [Confidentiality],
Section 5.10 [Access to Records] and Section 10. [Non-Compete], after the
expiration of the periods provided in such Sections; with respect to claims for
breach of Buyer's covenants in Section 5.9. [Additional Insured], Section 5.10.
[Access to Records], or Section 5.11 [Confidentiality], after the expiration of
the periods provided in such Sections.

            7.4.2 No Claim for indemnification under Section 7.1 or 7.2 shall be
made by Buyer Indemnified Parties or Seller Indemnified Parties with respect to
or involving third-party actions, demands, claims or Damages after the third

      7.5 Notice. Any claim by an indemnified party for Damages under Sections
7.1. or 7.2. will be made in writing and will state in detail the basis on which
the claim for Damages is made. The indemnified party may not take (i) legal
action against the indemnifying party or (ii) offset Damages against payments
due the indemnified party under this Agreement unless such written claim has
been given and the indemnifying party has not given notice to the indemnified
party of a bona fide objection within twenty (20) days after


                                       24
<PAGE>

the indemnified party notice is given, in which event no offset shall be
permitted until after the entry of a final and unappealable judgement of a court
of competent jurisdiction.

      7.6 Third-Party Actions.

            7.6.1 All claims for indemnification under Section 7.1. or 7.2.
involving third-party actions or demands shall be made in accordance with the
procedure set forth in this Section 7.6.

            7.6.2 Promptly after receipt by an indemnified party of notice of
any third-party action or demand which gives rise to Damages, such indemnified
party shall notify the indemnifying party. Failure so to notify the indemnifying
party shall relieve it of any liability that it may have to any indemnified
party to the extent that the defense of such action is materially prejudiced by
such failure, provided the indemnifying party did not receive or otherwise have
actual notice thereof.

            7.6.3 The indemnifying party shall be entitled to participate in the
defense of the third-party action or demand and, at its option, to assume the
defense thereof with counsel reasonably satisfactory to the indemnified party
provided (i) that the indemnifying party confirm that the action or demand is
covered by its indemnification obligation or, if not, that the indemnified party
be entitled to participate in the defense, and (ii) Buyer reserves the right to
retain control of the defense of any action or demand which could reasonably be
expected to materially affect Buyer's on-going operations or materially exceed
the maximum indemnity amount payable by Seller under Section 7.1. hereof. If the
indemnifying party receives notice of any action or demand, it shall promptly
notify the indemnified party as to whether it intends to control the defense
thereof.

            7.6.4 If notice is given to an indemnifying party of the
commencement of any action and it does not, within 20 days after the indemnified
party's notice is given, give notice to the indemnified party of its election to
assume the defense thereof, the indemnified party shall be entitled to assume
the defense thereof until such time as the indemnifying party elects to assume
the defense thereof. In such event, the indemnifying party shall not be bound by
any compromise or settlement thereof effected by the indemnified party without
its consent, which shall not be unreasonably withheld.

      7.7 Waiver of Subrogation. To the extent permitted by each Party's general
liability insurance policy, subrogation for all claims, losses, damages, costs
and expenses is hereby waived. Evidence of such waiver shall be delivered to the
other Party upon written request.

      7.8 Set-Off Rights. Either Party may, from time to time, set-off against
any amounts due to the other under this Agreement an amount equal to the
aggregate amount of the uncontested Damages. This right of set-off shall
continue unimpaired and shall not be exhausted by a single exercise thereof. The
right of set-off specified herein shall not be


                                       25
<PAGE>

deemed to impair or preclude the exercise by either Party of any other right or
remedy it/he might have on account of the existence of any Damages or breach or
violation of this Agreement by the other Party.

      7.9 Exclusive Remedy. Except for Section 18 of this Agreement, the parties
agree that all claims for Damages shall be brought against the other Party
pursuant to this Article 7 only.

8. Absence of Liabilities. Seller has no material liabilities except as and to
the extent reflected on the Closing Financial Statement or in this Agreement or
in any Exhibit hereto. Seller shall have no material liabilities arising after
the Closing Financial Statement except those liabilities created in the ordinary
course of business of the Seller and not assumed by the Buyer hereunder, all of
which shall be paid or reserved for by Seller as of the Closing.

9. Further Assurances After Closing. At any time and from time to time after the
Closing Date, at Buyer's reasonable request and without further consideration,
Seller shall promptly execute and deliver all such further instruments or
documents or perform such acts as Buyer may reasonably request in order to more
fully consummate the transactions contemplated herein.

10. Restrictive Covenant.

      10.1 Covenant Not to Compete. Seller and Shareholder jointly and severally
covenant and agree that they shall not, for a period of five (5) years after the
Closing Date in the counties of Carbon, Columbia, Lackawanna, Luzerne, Monroe,
Pike, Schuylkill, Sullivan, and Wyoming in the Commonwealth of Pennsylvania,
except with the express prior written consent of Buyer (the execution of which
shall be in Buyer's sole and absolute discretion) or except in connection with
Shareholder's employment with Buyer and for the sole benefit of Buyer, directly
or indirectly, whether as owner, principal, member, stockholder (registered or
beneficial), partner, joint venturer, trust, trustee, executor, administrator,
director, officer, employee, agent, representative, consultant, independent
contractor, investor, financier, lender, operator, manager, guarantor,

<PAGE>

unenforceable because of the area covered, the duration thereof, or the scope
thereof, then the court making such determination shall reduce the area and/or
duration and/or limit the scope thereof, and the covenant or agreement shall
then be enforceable in its reduced form.

                                       28

for material breach or violation by Buyer, or (iii) the Closing Date is not
extended by agreement of the Parties for any or no reason (the "Termination
Date"), Buyer shall pay Seller a "Break-up Fee" in the amount of Two Hundred
Thousand Dollars ($200,000) on, as and at the Termination Date. For each thirty

Break-up Fee shall increase by Fifty Thousand Dollars ($50,000). At the election
of Buyer, this Break-up Fee may be paid in the form of Response Shares equal in

the Securities and Exchange Commission ("SEC"), on or before Ninety (90) days
after the Termination Date in order that such Response Shares become
unrestricted securities, able to be freely bought and sold without restriction
under all applicable statutes, laws, rules and regulations. The Agreed Value of
the Response Shares identified in this Section shall be guaranteed by Buyer for
a period of one (1) year following the effectiveness of the above described
registration statement pursuant to the procedures described in Section 3.1.6 of
this Agreement. No Break-up fee shall be due and owing in the event that Closing
actually occurs hereunder. This Break-up Fee shall be the sole and exclusive
obligation of Buyer to Seller in the event of a termination for any reason other
than the giving of a Notice pursuant to Section 3.4.2 (in which event there
shall be no Break-up Fee or liability owing from Buyer to Seller).
