Eligible Receivable, and each Transferred Receivable, together with the Related
Security, is owned (prior to its sale hereunder) by the Seller free and clear of
any Adverse Claim (other than any Adverse Claim arising solely as the result of
any action taken by the Purchaser).  When the Purchaser makes a Purchase of
Receivables, it shall acquire valid and perfected first priority ownership of
each Transferred Receivable and the Related Security and Collections with
respect thereto, free and clear of any Adverse Claim (other than any Adverse
Claim arising solely as the result of any action taken by the Purchaser), and no

in connection with any Adverse Claim arising solely as the result of any action
taken by the Purchaser.

     (j)  Each Receivable Report (if prepared by the Seller, or to the extent
that information contained therein is supplied by the Seller), exhibit,
financial statement or report furnished or to be furnished at any time by the
Seller to the Purchaser in connection with this Agreement is or will be accurate
in all material respects as of its date or as of the date so furnished, and no
such document contains or will contain any untrue statement of a material fact
or omits or will omit to state a material fact necessary in order to make the
statements contained therein, in the light of the circumstances under which they
were made, not misleading.

     (k)  The principal place of business and chief executive office of the
Seller and the office where the Seller keeps its records concerning the
Transferred Receivables are located at the address referred to in Section
5.01(b).  

     (l)  The Seller is not known by and does not use any tradename or
doing-business-as name other than Triple A Protection and Rampart Security
Systems.

     (m)  With respect to any program used by the Seller in the servicing of the
Receivables, no sublicensing agreement is necessary in connection with the
designation of a new Collection Agent pursuant to Section 6.01(b) so that such
new Collection Agent shall have the benefit of such programs.

     (n)  The transfers of Transferred Receivables by the Seller to the
Purchaser pursuant to this Agreement, and all other transactions between the
Seller and the Purchaser, have been and will be made in good faith and without
intent to hinder, delay or defraud creditors of the Seller.

     (o)  (i)  The fair value of the property of the Seller is greater than the
total amount of liabilities, including contingent liabilities, of the Seller,
(ii) the present fair salable value of the assets of the Seller is not less than
the amount that will be required to pay all probable liabilities of the Seller
on its debts as they become absolute and matured, (iii) the Seller does not
intend to, and does not believe that it will, incur debts or liabilities beyond
its ability to pay such debts and liabilities as they mature and (iv) the Seller
is not engaged in a business or a transaction, and is not about to


                                          12


engage in a business or a transaction, for which its property would constitute
unreasonably small capital.

     (p)  (i)  Each Transferred Contract (A) arose in connection with a bona
fide final sale and delivery of a security alarm system and/or related service
in the ordinary course of business; (B) is for a liquidated amount as stated in
such Contract; (C) is not subject to any defense, deduction, offset or
counterclaim; (D) constitutes the valid, legal and binding obligations of the
Originator or its predecessor-in-interest, enforceable in accordance with its
terms; (E) complies with all federal, state and local laws, rules and
regulations and (F) as of the date of its inclusion in a Receivable Report
hereunder, the Receivables thereunder are Eligible Receivables.

          (ii) With respect to each Transferred Contract, (A) the Obligor
     thereon has acknowledged that the security system dealer originally a party
     thereto has completed all necessary work contracted for and has received a
     notice of his rights of rescission under federal and state law with respect
     thereto, (B) the Obligor has not exercised any such rescission rights
     within five business days after the time such notice of rescission rights
     was signed by such Obligor, (C) the Obligor thereon is obligated and liable
     for payment of the amounts stated in such Contract, and has no known reason
     to exercise any right of rejection, return, offset, defense, counterclaim,
     discount or deduction.

          (iii)     Each Transferred Contract contains valid mandatory deferred
     payment obligations for the mandatory monitoring of the security system
     purchased, leased or owned by the Obligor, legally enforceable in
     accordance with its terms, representing actual and bona fide agreements to
     perform and accept residential monitoring services.

          (iv) No payment under any Transferred Contract is, as of the relevant
     Closing Date, delinquent, in default or subject to any dispute.  All
     statements made in any Financed Contract, including names and addresses,
     locations and descriptions of property or services, down-payments and
     unpaid balances, are in all respects true, complete and accurate.  All
     signatures and endorsements that appear on each Transferred Contract, or
     any agreement or instrument relating thereto, are genuine and all
     signatories and endorsers, if any, have full legal capacity to contract.

          (v)  All of the Seller's obligations to the Obligor on any Transferred
     Contract, with the exception of future monitoring services and maintenance
     or service obligations, have been completed and fulfilled in their
     entirety.  No Obligor on any Transferred Contract has been induced to enter
     into such Contract by fraud or misrepresentation as to price, quality of
     products or services.

and maintain its corporate existence, rights, franchises, qualifications and
privileges except to the extent that the failure so to comply with any such law,

perform its obligations under this Agreement.

regarding payments to be made to the Lockbox.

     (i)  DEPOSITS TO LOCKBOX.     Except as otherwise specified by the
Purchaser, the Seller will deposit, or cause to be deposited, all Collections of

     (j)  FURTHER ASSURANCES.

          (i).   The Seller will from time to time, at its expense, promptly
     execute and deliver all further instruments and documents, and take all
     further actions, that may be reasonably necessary or desirable, or that the

     meaning of Section 4001(a)(3) of ERISA) to which the Seller or any
     Affiliate is or was, within the preceding five years, a contributing
     employer, in each case in respect of the assessment of withdrawal liability
     or an event or condition which could, in the aggregate, result in the

the Purchaser have structured this Agreement with the intention that each
Purchase of Receivables hereunder be treated as a sale of such Receivables by
the Seller to the Purchaser for all purposes.  The Seller and the Purchaser
shall record each Purchase as a sale or purchase, as the case may be, on its
books and records, and reflect each Purchase in its financial statements and tax
returns as a sale or purchase, as the case may be.  If, contrary to the mutual
intent of the Seller and the Purchaser, any Purchase of Receivables hereunder is
not characterized as a sale, the Seller shall, effective as of the date hereof,
be deemed to have granted (and the Seller hereby does grant) to the Purchaser a
first priority security interest in and to any and all Receivables and the
proceeds thereof and all of the Seller's rights in any computer software, disks
and the like necessary or desirable for collection of the Contracts, all to
secure the repayment of all amounts advanced to the Seller hereunder with
accrued interest thereon, and this Agreement shall be deemed to be a security
agreement.

                                      ARTICLE VI

                            ADMINISTRATION AND COLLECTION

     SECTION 6.01   DESIGNATION OF THE COLLECTION AGENT.    The servicing,
administration and collection of the Transferred Receivables shall be conducted
by such Person (the "COLLECTION AGENT") so designated hereunder from time to
time.  The Seller is hereby designated as, and hereby agrees to perform the
duties and obligations of, the Collection Agent pursuant to the terms hereof. 
The Purchaser or its designee or assign at any time following the occurrence and
during the continuance of an Event of Termination may designate as Collection
Agent any other Person (including itself) to succeed the Seller or any successor
Collection Agent, if such Person shall consent and agree to the terms hereof.  
Upon the Seller's receipt of such notice, the Seller agrees that it will
terminate its activities as Collection Agent hereunder in a manner which the
Purchaser (or its assign) believes will facilitate the transition of the
performance of such activities to the new Collection Agent, and the Seller shall
use its best efforts to assist the Purchaser (or its assign) to take over the
servicing, administration and collection of the Transferred Receivables,
including, without limitation, providing access to and copies of all computer
tapes or disks and other documents or instruments that evidence or relate to
Transferred Receivables maintained in its capacity as Collection Agent and
access to all employees and officers of the Seller responsible with respect
thereto.  The Purchaser at any time after giving such notice may designate as
Collection Agent any Person (including itself) to succeed the Seller or any
successor Collection Agent, if such Person shall consent and agree to the terms
hereof.  The Collection Agent may, with the prior consent of the Purchaser,
subcontract with any other Person for the servicing, administration or
collection of Transferred Receivables.  Any such subcontract shall not affect
the Collection Agent's liability for performance of its duties and obligations
pursuant to the terms hereof.

     SECTION 6.02   DUTIES OF THE COLLECTION AGENT.

     (a)  The Collection Agent shall take or cause to be taken all such actions
as may be necessary or advisable to collect each Transferred Receivable from
time to time, all in accordance with applicable Requirements of Law, with
reasonable care and diligence, and in accordance with the Credit and Collection
Policy.  The Purchaser hereby appoints the Collection Agent, from time to time
designated pursuant to Section 6.01, as agent to enforce its ownership and other
rights in the Transferred Receivables, the Related Security and the Collections
with respect thereto.  In performing its duties as Collection Agent, the
Collection Agent shall exercise the same care and apply the same policies as it
would exercise and apply if it owned the Transferred Receivables and shall act
in the best interests of the Purchaser and its assignees.

     (b)  Prior to the tenth Business Day of each month, the Collection Agent
shall prepare and forward to the Purchaser (i) a Seller Report relating to all
then outstanding Transferred Receivables and the Related Security and
Collections with respect thereto, in each case, as of the close of business on
the last day of the immediately preceding month and (ii) a listing by Obligor of
all Transferred Receivables correlating Transferred Receivables and Purchases,
together with an aging report of such Transferred Receivables.


                                          18


     (c)  If no Event of Termination or Incipient Event of Termination shall
have occurred and be continuing, the Seller, while it is the Collection Agent,
may, in accordance with the Credit and Collection Policy, extend the maturity or
adjust the Outstanding Balance of any Transferred Receivable as the Seller deems
appropriate to maximize Collections thereof.

     (d)  The Seller shall deliver to the Collection Agent, and the Collection
Agent shall hold in trust for the Seller and the Purchaser in accordance with
their respective interests, all documents, instruments and records (including,
without limitation, computer tapes or disks) which evidence or relate to
Transferred Receivables other than those required to be transferred to and held
by another party pursuant to the Financing Agreement.

     (e)  The Collection Agent shall, as soon as practicable following receipt,
return to the Seller any cash collections or other cash proceeds received with
respect to Receivables not constituting Transferred Receivables, less, in the
event the Seller is not the Collection Agent, all reasonable and appropriate
out-of-pocket costs and expenses of the Collection Agent of servicing,
collecting and administering the Receivables to the extent not covered by the
Collection Agent Fee received by it.

     (f)  The Collection Agent also shall perform the other obligations of the
Collection Agent set forth in this Agreement with respect to the Transferred
Receivables. 

     (g)  In addition to its other duties specified herein, the Collection Agent
shall, until its duties hereunder are terminated by the Purchaser, contract for
the performance of all monitoring services required under each Contract as if
such Contract had not been sold by the Purchaser hereunder.

     SECTION 6.03   COLLECTION AGENT FEE.    The Purchaser shall pay to the
Collection Agent, so long as it is acting as the Collection Agent hereunder, a
periodic collection fee (the "COLLECTION AGENT FEE") of $5.00 per month for each
Contract that is a Transferred Contract for such month (other than any Contract
related to a Transferred Receivable that is a Defaulted Receivable), payable on
each Settlement Date or such other day during each calendar month as the
Purchaser and the Collection Agent shall agree.  The payment of the Collection
Agent Fee shall be made to the extent and in the manner provided in the
Financing Agreement.

     SECTION 6.04   CERTAIN RIGHTS OF THE PURCHASER.

     (a)  The Purchaser may, at any time, give notice of ownership and/or direct
the Obligors of Transferred Receivables and any Person obligated on any Related
Security, or any of them, that payment of all amounts payable under any
Transferred Receivable shall be made directly to the Purchaser or its designee. 
The Seller hereby transfers to the Purchaser (and its assigns) the exclusive
ownership and control of the Lockbox.


                                          19


     (b)  The Seller shall, at any time upon the Purchaser's request and at the
Seller's expense, give notice of its ownership of the Transferred Receivables to
each Obligor thereof and direct that payments of all amounts payable under such
Transferred Receivables be made directly to the Purchaser or its designee.

     (c)  At the Purchaser's request and at the Seller's expense, the Seller and
the Collection Agent shall (i) assemble all documents, instruments and other
records (including, without limitation, computer tapes and disks) that evidence
or relate to the Transferred Receivables and the related Contracts and Related
Security, or that are otherwise necessary or desirable to collect the
Transferred Receivables, and shall make the same available to the Purchaser at a
place selected by the Purchaser or its designee and (ii) segregate all cash,
checks and other instruments received by it from time to time constituting
Collections of Transferred Receivables in a manner acceptable to the Purchaser
and, promptly upon receipt, remit all such cash, checks and instruments, duly
indorsed or with duly executed instruments of transfer, to the Lockbox.  The
Purchaser shall also have the right to make copies of all such documents,
instruments and other records at any time.

     (d)  The Seller authorizes the Purchaser to take any and all steps in the
Seller's name and on behalf of the Seller that are reasonably necessary or
desirable, in the determination of the Purchaser, to collect amounts due under
the Transferred Receivables, including, without limitation, endorsing the
Seller's name on checks and other instruments representing Collections of
Transferred Receivables and enforcing the Transferred Receivables and the
Related Security and related Contracts.

     SECTION 6.05   RIGHTS AND REMEDIES.

     (a)  If the Seller or the Collection Agent fails to perform any of its
obligations under this Agreement, the Purchaser may (but shall not be required
to), if such failure continues more than five Business Days following receipt of
written notice from the Purchaser,  itself perform, or cause performance of,
such obligation, and, if the Seller (as Collection Agent or otherwise) fails to
so perform, the costs and expenses of the Purchaser incurred in connection
therewith shall be payable by the Seller as provided in Section 8.01 or Section
9.04 as applicable.

     (b)  The Seller shall perform all of its obligations under the Contracts
related to the Transferred Receivables to the same extent as if the Seller had
not sold Receivables hereunder and the exercise by the Purchaser of its rights
hereunder shall not relieve the Seller from such obligations or its obligations
with respect to the Transferred Receivables.  The Purchaser shall not have any
obligation or liability with respect to any Transferred Receivables or related
Contracts, nor shall the Purchaser be obligated to perform any of the
obligations of the Seller thereunder.

     (c)  The Seller shall cooperate with the Collection Agent in collecting
amounts due from Obligors in respect of the Transferred Receivables.

     (d)  The Seller hereby grants to the Collection Agent an irrevocable power
of attorney, with full power of substitution, coupled with an interest, to take
in the name of the Seller all steps



                                          20


necessary or advisable to endorse, negotiate or otherwise realize on any writing
or other right of any kind held or transmitted by the Seller or transmitted or
received by Purchaser (whether or not from the Seller) in connection with any
Transferred Receivable.

     SECTION 6.06   TRANSFER OF RECORDS TO PURCHASER.       Each Purchase of
Receivables hereunder shall include the transfer to the Purchaser of all of the
Seller's right and title to and interest in the records relating to such
Receivables and shall include an irrevocable non-exclusive license to the use of
the Seller's computer software system to access and create such records.  Such
license shall be without royalty or payment of any kind, is coupled with an
interest, and shall be irrevocable until all of the Transferred Receivables are
either collected in full or become Defaulted Receivables.  The Seller shall take
such action requested by the Purchaser, from time to time hereafter, that may be
necessary or appropriate to ensure that the Purchaser has an enforceable
ownership interest in the records relating to the Transferred Receivables and
rights (whether by ownership, license or sublicense) to the use of the Seller's
computer software system to access and create such records.  In recognition of
the Seller's need to have access to the records transferred to the Purchaser
hereunder, the Purchaser hereby grants to the Seller an irrevocable license to
access such records in connection with any activity arising in the ordinary
course of the Seller's business or in performance of its duties as Collection
Agent, PROVIDED that (i) the Seller shall not disrupt or otherwise interfere
with the Purchaser's use of and access to such records during such license
period and (ii) the Seller consents to the assignment and delivery of the
records (including any information contained therein relating to the Seller or
its operations) to any assignees or transferees of the Purchaser provided they
agree to hold such records confidential.

                                EVENTS OF TERMINATION

     SECTION 7.01   EVENTS OF TERMINATION.   If any of the following events
(each, an "EVENT OF TERMINATION") shall occur and be continuing:

     (a)  the Collection Agent (if the Seller or any of its Affiliates) shall
fail (i) to perform or observe any term, covenant or agreement under this
Agreement (other than as referred to in clause (ii) of this subsection (a) or
subsection (d) below) and such failure shall remain unremedied for the greater
of ten Business Days after actual knowledge thereof by a responsible officer of
the Collection Agent and five Business Days after written notice by the
Purchaser or its assign or (ii) to make when due any payment or deposit to be
made by it under this Agreement three Business Days after the same is due; or

     (b)  the Seller shall fail to make any payment required hereunder three
Business Days after the same is due; or

     (c)  any representation or warranty made or deemed made by the Seller in
this Agreement or any information or report delivered by the Seller pursuant to
this Agreement shall prove to have


                                          21


been incorrect or untrue in any material respect when made or deemed made or
delivered and, if, in the reasonable determination of the Purchaser or its
assign, such failure can be corrected within 15 days, either the Seller is not
making its best efforts to remedy the same or such failure shall continue
unremedied for 20 days after the earlier of actual knowledge by a responsible
officer of the Purchaser and written notice thereof by the Purchaser or its
assign; or

     (d)  the Seller shall fail to perform or observe any of the following
provisions of this Agreement: the first sentence of Section 5.01(b); Section
5.01(d); Section 5.01(h); Section 5.01(k)(iii)-(v); Section 5.01(l); or Section
6.02(b); or

     (e)  the Seller shall fail to pay any principal of or premium or interest
on any of its Debt  which is outstanding in a principal amount of at least
$250,000 when the same becomes due and payable (whether by scheduled maturity,
required prepayment, acceleration, demand or otherwise), and such failure shall
continue after the applicable grace period, if any, specified in the agreement
or instrument relating to such Debt; or any other event shall occur or condition
shall exist under any agreement or instrument relating to any such Debt and
shall continue after the applicable grace period, if any, specified in such
agreement or instrument, if the effect of such event or condition is to
accelerate, or to permit the acceleration of, the maturity of such Debt; or any
such Debt shall be declared to be due and payable, or required to be prepaid
(other than by a regularly scheduled required prepayment), redeemed, purchased
or defeased, or an offer to repay, redeem, purchase or defease such Debt shall
be required to be made, in each case prior to the stated maturity thereof; or

     (f)  any Purchase of Receivables, the Related Security and the Collections
with respect thereto  hereunder shall for any reason cease to constitute valid
and perfected ownership of such Receivables, Related Security and Collections
free and clear of any Adverse Claim; or

     (g)  the Seller shall admit in writing its inability to pay its debts
generally, or shall make a general assignment for the benefit of creditors; or
any proceeding shall be instituted by or against the Seller seeking to
adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up,
reorganization, arrangement, adjustment, protection, relief, or composition of
it or its debts under any law relating to bankruptcy, insolvency or
reorganization or relief of debtors, or seeking the entry of an order for relief
or the appointment of a receiver, trustee, custodian or other similar official
for it or for any substantial part of its property and, in the case of any such
proceeding instituted against it (but not instituted by it), either such
proceeding shall remain undismissed or unstayed for a period of 60 days, or any
of the actions sought in such proceeding (including, without limitation, the
entry of an order for relief against, or the appointment of a receiver, trustee,
custodian or other similar official for, it or for any substantial part of its
property) shall occur; or the Seller shall take any corporate action to
authorize any of the actions set forth above in this subsection (g); or 

     (h)  an Event of Default shall have occurred under the Finance Agreement;
or

     (i)  there shall have occurred any material adverse change in the financial
condition or operations of the Seller since the date hereof; or there shall have
occurred any event which may


                                          22


materially adversely affect the collectibility of the Transferred Receivables or
the ability of the Seller to collect Transferred Receivables or otherwise
perform its obligations under this Agreement; 

then, and in any such event, the Purchaser may, by notice to the Seller, take
either or both of the following actions:  (x) declare the Facility Termination
Date to have occurred (in which case the Facility Termination Date shall be
deemed to have occurred) and (y) without limiting any right under this Agreement
to replace the Collection Agent, designate another Person to succeed the Seller
as Collection Agent; PROVIDED, that, automatically upon the occurrence of any
event (without any requirement for the passage of time or the giving of notice)
described in paragraph (g) of this Section 7.01, the Facility Termination Date
shall occur, the Seller (if it is then serving as the Collection Agent) shall
cease to be the Collection Agent, and the Purchaser (or its assigns or
designees) shall become the Collection Agent.  Upon any such declaration or
designation or upon such automatic termination, the Purchaser shall have, in
addition to the rights and remedies under this Agreement, all other rights and
remedies with respect to the Receivables provided after default under the UCC
and under other applicable law, which rights and remedies shall be cumulative. 


                                    ARTICLE VIII
                                          
                                  INDEMNIFICATION

     SECTION 8.01   INDEMNITIES BY THE SELLER.    Without limiting any other
rights which the Purchaser may have hereunder or under applicable law, the
Seller hereby agrees to indemnify the Purchaser and its assigns and transferees
(each, an "INDEMNIFIED PARTY") from and against any and all damages, claims,
losses, liabilities and related costs and expenses, including reasonable
attorneys' fees and disbursements (all of the foregoing being collectively
referred to as "INDEMNIFIED AMOUNTS"), awarded against or incurred by any
Indemnified Party arising out of or as a result of:

     (a)  the inclusion, or purported inclusion, in any Purchase of any
Receivable that is not an Eligible Receivable on the date of such Purchase, or
the characterization in any Receivables Report or other statement made by the
Seller of any Transferred Receivable as an Eligible Receivable which is not an
Eligible Receivable as of the date of such Receivables Report or statement;

     (b)  any failure by the Purchaser to obtain full payment with respect to
any Government Receivable 180 days after the same becomes payable or any failure
by the Purchaser to obtain a perfected ownership interest in any Government
Receivable;

     (c)  any representation or warranty made or deemed made by the Seller under
this Agreement, which shall have been incorrect in any material respect when
made;

     (d)  the failure by the Seller to comply with any applicable law, rule or
regulation with respect to any Transferred Receivable or the related Contract;
or the failure of any Transferred Receivable or the related Contract to conform
to any such applicable law, rule or regulation;


                                          23


     (e)  the failure to vest in the Purchaser absolute ownership of the
Receivables that are, or that purport to be, the subject of a Purchase under
this Agreement and the Related Security and Collections in respect thereof, free
and clear of any Adverse Claim;

     (f)  the failure of the Seller to have filed, or any delay in filing,
financing statements or other similar instruments or documents under the UCC of
any applicable jurisdiction or other applicable law with respect to any
Receivable that is, or that purports to be, the subject of a Purchase under this
Agreement and the Related Security and Collections in respect thereof, whether
at the time of any Purchase or at any subsequent time;

     (g)  any dispute, claim, offset or defense (other than discharge in
bankruptcy of the Obligor) of the Obligor to the payment of any Receivable that
is, or that purports to be, the subject of a Purchase under this Agreement
(including, without limitation, a defense based on such Receivable or the
related Contract not being a legal, valid and binding obligation of such Obligor
enforceable against it in accordance with its terms), or any other claim
resulting from the sale of the merchandise or services related to such
Receivable or the furnishing or failure to furnish such merchandise or services
or relating to collection activities with respect to such Receivable (if such
collection activities were performed by the Seller acting as Collection Agent)
except to the extent that such dispute, claim, offset or defense results solely
from actions or failures to act of the Purchaser or its assigns;

     (h)  any failure of the Seller, as Collection Agent or otherwise, to
perform its duties or obligations in accordance with the provisions hereof or to
perform its duties or obligations under any Contract related to a Transferred
Receivable;

     (i)  any products liability or other claim arising out of or in connection
with services which are the subject of any Contract; 

     (j)  the commingling of Collections of Transferred Receivables by the
Seller or a designee of the Seller, as Collection Agent or otherwise, at any
time with other funds of the Seller or an Affiliate of the Seller;

     (k)  any investigation, litigation or proceeding related to this Agreement
or the use of proceeds of Purchases or the ownership of Receivables, the Related
Security or Collections with respect thereto or in respect of any Receivable,
Related Security or Contract, except to the extent any such investigation,
litigation or proceeding relates to a possible matter involving an Indemnified
Party for which neither the Seller nor any of its Affiliates is at fault;

     (l)  any failure of the Seller to comply with its covenants contained in
Section 5.01;

     (m)  any Collection Agent Fees or other costs and expenses payable to any
replacement Collection Agent, to the extent in excess of the Collection Agent
Fees payable to the Seller hereunder;


                                          24


     (n)  any claim brought by any Person other than an Indemnified Party
arising from any activity by the Seller or any Affiliate of the Seller in
servicing, administering or collecting any Transferred Receivable; or 

     (o)  any Dilution with respect to any Transferred Receivable. 

It is expressly agreed and understood by the parties hereto (i) that the
foregoing indemnification is not intended to, and shall not, constitute a
guarantee of the collectibility or payment of the Transferred Receivables and
(ii) that nothing in this Section 8.01 shall require the Seller to indemnify any
Person (A) for Receivables which are not collected, not paid or uncollectible on
account of the insolvency, bankruptcy, or financial inability to pay of the
applicable Obligor, (B) for damages, losses, claims or liabilities or related
costs or expenses resulting from such Person's gross negligence or willful
misconduct or (C) for any income taxes or franchise taxes incurred by such
Person arising out of or as a result of this Agreement or in respect of any
Transferred Receivable or any Contract. 


                                     ARTICLE IX
                                          
                                   MISCELLANEOUS

     SECTION 9.01   AMENDMENTS, ETC.    No amendment or waiver of any provision
of this Agreement or consent to any departure by the Seller therefrom shall be
effective unless in a writing signed by the Purchaser and, in the case of any
amendment, also signed by the Seller, and then such amendment, waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given.  No failure on the part of the Purchaser to exercise, and no
delay in exercising, any right hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise of any right hereunder preclude any other
or further exercise thereof or the exercise of any other right.

     SECTION 9.02   NOTICES, ETC.  All notices and other communications
hereunder shall, unless otherwise stated herein, be in writing (which shall
include facsimile communication) and be faxed or delivered, to each party
hereto, at its address set forth under its name on the signature pages hereof or
at such other address as shall be designated by such party in a written notice
to the other parties hereto.  Notices and communications by facsimile shall be
effective when sent (and shall be followed by hard copy sent by regular mail),
and notices and communications sent by other means shall be effective when
received.

     SECTION 9.03   BINDING EFFECT; ASSIGNABILITY.

     (a)  This Agreement shall be binding upon and inure to the benefit of the
Seller, the Purchaser and their respective successors and assigns; PROVIDED,
HOWEVER, that the Seller may not assign its rights or obligations hereunder or
any interest herein without the prior written consent of


                                          25


the Purchaser.  In connection with any sale or assignment by the Purchaser of
all or a portion of the Transferred Receivables, the buyer or assignee, as the
case may be, shall, to the extent of its purchase or assignment, have all rights
of the Purchaser under this Agreement (as if such buyer or assignee, as the case
may be, were the Purchaser hereunder) except to the extent specifically provided
in the agreement between the Purchaser and such buyer or assignee, as the case
may be.

     (b)  This Agreement shall create and constitute the continuing obligations
of the parties hereto in accordance with its terms, and shall remain in full
force and effect until such time, after the Facility Termination Date, when all
of the Transferred Receivables are either collected in full or become Defaulted
Receivables; PROVIDED, HOWEVER, that rights and remedies with respect to any
breach of any representation and warranty made by the Seller pursuant to Article
IV and the provisions of Article VIII and Sections 9.04, 9.05 and 9.06 shall be
continuing and shall survive any termination of this Agreement.

     SECTION 9.04   COSTS, EXPENSES AND TAXES.    In addition to the rights of
indemnification granted to the Purchaser pursuant to Article VIII, the Seller
agrees to pay on demand all reasonable costs and expenses, if any (including
reasonable counsel fees and expenses), in connection with the enforcement of
this Agreement and the other documents to be delivered hereunder EXCLUDING,
HOWEVER, any costs of enforcement or collection of Transferred Receivables.  

     SECTION 9.05   NO PROCEEDINGS.     The Seller hereby agrees that it will
not institute against the Purchaser any proceeding of the type referred to in
Section 7.01(g) so long as there shall not have elapsed one year plus one day
since the later of (a) the Facility Termination Date and (b) the date on which
all of the Transferred Receivables are either collected in full or become
Defaulted Receivables.

     SECTION 9.06   CONFIDENTIALITY.    Unless otherwise required by applicable
law or the rules of any exchange on which the shares of Response USA, Inc. are
listed, each party hereto agrees to maintain the confidentiality of this
Agreement in communications with third parties and otherwise; PROVIDED that this
Agreement may be disclosed to (a) third parties to the extent such disclosure is
made pursuant to a written agreement of confidentiality in form and substance
reasonably satisfactory to the other party hereto and (b) such party's legal
counsel and auditors and the Purchaser's assignees, if they agree in each case
to hold it confidential. 

     SECTION 9.07   GOVERNING LAW. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York (without giving
effect to the conflict of laws principles thereof), except to the extent that
the perfection of the Purchaser's ownership of or security interest in the
receivables or remedies hereunder, in respect thereof, are governed by the laws
of a jurisdiction other than the State of New York.

     SECTION 9.08   THIRD PARTY BENEFICIARY. Each party hereto hereby
acknowledges that the Purchaser may assign all or any portion of its rights
under this Agreement and that such assignees may (except as otherwise agreed to
by such assignees) further assign their rights under this


                                          26


Agreement, and the Seller hereby consents to any such assignments.  All such
assignees, including parties to the Finance Agreement in the case of assignment
to such parties, shall be third party beneficiaries of, and shall be entitled to
enforce the Purchaser's rights and remedies under, this Agreement to the same
extent as if they were parties thereto, except to the extent specifically
limited under the terms of their assignment.

     SECTION 9.09   EXECUTION IN COUNTERPARTS.    This Agreement may be executed
in any number of counterparts, each of which when so executed shall be deemed to
be an original and all of which when taken together shall constitute one and the
same agreement.  

          IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed by their respective officers thereunto duly authorized, as of the date
first above written.
