the Administrative Agent for payment on the Administrative Questionnaire, in
U.S. Dollars and in immediately available funds, such Lender's pro rata share of
the requested Revolving Loan. The Administrative Agent will promptly make such
amounts available to Borrower by depositing to the Loan Account the aggregate of
such amounts so made available to the Administrative Agent in the type of funds
received.

         Section 2.1.5. RELATIONSHIP OF REVOLVING LOANS TO TOTAL REVOLVING LOAN
COMMITMENT AMOUNT. Each Revolving Loan shall consist of either an Existing Loan
continued by or a Revolving Loan made by each Lender with a Revolving Loan
Commitment in respect of its Revolving Loan Commitment, which Revolving Loan
shall be continued or made by each Lender in the proportion that such Lender's
Revolving Loan Commitment bears to the Total Revolving Loan Commitment Amount;
PROVIDED, HOWEVER, that, except as provided in Section 2.2. hereof, if at any
time, for any reason, the proportion that any such Lender's Unused Revolving
Loan Commitment bears to the Unused Total Revolving Loan Commitment Amount is
not equal to the proportion that the Revolving Loan Commitment of such Lender
bears to the Total Revolving Loan Commitment Amount, then, each such Lender
shall promptly purchase or sell, as may be necessary, participations in the
Revolving Loans held by the other Lenders in such amounts as will (but only if
and to the extent that the purchase of such participations would not cause any
Lender to have outstanding Revolving Loans in an amount in excess of its
Revolving Loan Commitment and would not cause any Lender to exceed its lending
limit or to violate any other legal requirement to which it is subject), and
make such other adjustments from time to time as shall be necessary to, cause
the proportion that such Lender's Unused Revolving Loan Commitment bears to the
Unused Total Revolving Loan Commitment Amount to be equal to the proportion that
such Lender's Revolving Loan Commitment bears to the Total Revolving Loan
Commitment Amount.

         Section 2.1.6. LOAN ACCOUNT. Each Revolving Loan shall be recorded in
the Loan Account in accordance with Section 2.6.9.

         Section 2.1.7. SEVERAL OBLIGATIONS. The failure of any Lender with a
Revolving Loan Commitment to make available its proportionate share of any
Revolving Loan on the date specified therefor shall not relieve any other Lender
with a Revolving Loan Commitment of its obligation to make available its
proportionate share of such Revolving Loans on such date, but no Lender shall be
responsible for the failure of any other Lender to make available such other
Lender's proportionate share of the Revolving Loan.

         Section 2.1.8. CALCULATION OF BORROWING BASE. The Borrowing Base as of
any time shall be calculated by reference to the most recent RMR Report and
other financial reports delivered by Borrower under Sections 6.1.2. or 7.2.3.
hereof and such other information as may be available to the Administrative
Agent, the Documentation Agent or the Lenders from time to time.

         Section 2.1.9. REVOLVING CREDIT NOTES. On the Closing Date, Borrower
shall issue to each of the Lenders with a Revolving Loan Commitment a promissory
note executed by Borrower in substantially the form attached hereto as EXHIBIT B
with all blanks appropriately completed in conformity with this Agreement (each
a "Revolving Credit Note" and, collectively, the "Revolving Credit Notes"), with
all blanks therein appropriately completed. The Revolving Credit Notes shall
evidence the obligation of Borrower to repay to the Lender to which it is issued
all Loans continued or made by such Lender to Borrower on account of such
Lender's Revolving Loan Commitment . Each Revolving Credit Note shall (i) be
payable to the Lender to which it is issued or its registered assigns, (ii) be
dated as of the Closing Date, (iii) be in a stated principal amount equal to the
Revolving Loan Commitment of such Lender, (iv) be payable in the principal
amount of such Lender's pro rata percentage of the Loans evidenced thereby, (v)
mature on the Maturity Date, (vi) bear interest as provided in Section 2.4.4.
hereof, (vii) be subject to voluntary prepayments as provided in Section 2.6.7.
hereof and mandatory prepayments as provided in Section 2.6.8. hereof and (viii)
be entitled to the benefit of this Agreement and the Other Documents, and all
security granted or provided to the Administrative Agent for the ratable benefit
of the Lenders thereunder. Each Lender shall prior to any transfer or assignment
of its Revolving Credit Note endorse on the reverse side thereof the outstanding
principal amounts of the Loans evidenced thereby; provided, however, that such
Lender's failure to make any such record or endorsement shall not affect
Borrower's obligations in respect thereof. In addition, following the
effectiveness of this Agreement, and, if possible, on the Closing Date, each of
the Lenders shall deliver to the Administrative Agent the notes or promptly
thereafter an affidavit of lost note then held by such Lender evidencing loans
and advances under the Third Restated Credit Agreement for delivery to and
cancellation by the Borrower.

         Section 2.1.10. PAYMENT OF PRINCIPAL. The aggregate unpaid principal
amount of all Revolving Loans, together with accrued and unpaid interest

accelerated by the Lenders following the occurrence of an Event of Default, be
repaid by Borrower in twenty (20) consecutive quarterly installments in an
amount equal to the following percentages of the outstanding principal amount of
the Revolving Loans on the Revolving Credit Termination Date commencing on April
30, 2000 and continuing on the last day of each succeeding calendar quarter
thereafter as follows:

         Section 2.1.11. USE OF PROCEEDS. Revolving Loans shall be used solely
for the working capital needs and general corporate purposes of Borrower, for
Permitted Acquisitions, for Direct Marketing Program Costs, for Dealer Program
Costs, to refinance the existing Indebtedness of Borrower set forth on SCHEDULE
2.1.11. attached hereto and to pay expenses associated with the consummation of
the transactions contemplated by this Agreement.

         Section 2.1.12. REDUCTION OF TOTAL REVOLVING LOAN COMMITMENT AMOUNT.
Borrower may from time to time, by written notice delivered to the
Administrative Agent at least five (5) Business Days prior to the date of the
requested reduction, reduce the Unused Total Revolving Loan Commitment Amount by
integral multiples of ONE MILLION AND NO/100 DOLLARS ($1,000,000.00). No
reduction of the Total Revolving Loan Commitment Amount shall be subject to
reinstatement.

         Section 2.2. SWINGLINE LOANS.

         Section 2.2.1. THE SWINGLINE. Upon the execution of this Agreement, the
Administrative Agent in its individual capacity hereby agrees to extend to
Borrower a line of credit, so that as long as no Default or Event of Default has
occurred and is continuing, the Administrative Agent agrees to lend to Borrower,
and Borrower may borrow, repay and reborrow, on a revolving basis, in one (1) or
more Swingline Loans from time to time during the period commencing on the
Closing Date and continuing through the close of business on the Revolving
Credit Termination Date, amounts which do not exceed at any one time outstanding
the Swingline Commitment (the "Swingline"). All Swingline Loans shall constitute
usage of the Administrative Agent's Revolving Loan Commitment under this
Agreement. Notwithstanding any provision of this Agreement to the contrary,
Swingline Loans (i) shall be made and maintained as Base Rate Loans, (ii) shall
be denominated in U.S. Dollars, (iii) may be repaid and reborrowed in accordance
with the provisions of this Agreement, (iv) shall not exceed in the aggregate at
any one time outstanding the Swingline Commitment and (v) shall not, together
with all Revolving Loans, exceed in the aggregate at any one time outstanding
the lesser of the Borrowing Base or the Total Revolving Loan Commitment Amount.

                                       31


         Section 2.2.2. NOTICE FOR SWINGLINE LOANS. Except as provided in
Section 2.2.4. hereof, whenever Borrower desires to obtain a Swingline Loan,
Borrower shall provide the Administrative Agent with written notice (or
telephonic notice promptly confirmed in writing) received at its Notice Office
no later than 12:00 noon (Boston, Massachusetts time) on the day on which the
requested Swingline Loan is to be made. Each such notice (a "Swingline Notice")
shall be irrevocable, be in substantially the form of EXHIBIT C attached hereto
and be appropriately completed to specify: (i) the amount of the requested
Swingline Loan and (ii) the effective date of such Swingline Loan. Borrower
hereby acknowledges and agrees that the Administrative Agent may, prior to the
receipt of written confirmation act without liability upon the basis of any
telephonic notice provided under this Section 2.2.2., believed by the
Administrative Agent, in good faith, to be from a Responsible Officer of
Borrower and Borrower hereby waives the right to dispute the Administrative
Agent's record of the terms of such telephonic notice. Notwithstanding the
foregoing, the Administrative Agent shall not make any Swingline Loans if the
Administrative Agent has received prior to the making of the requested Swingline
Loan a certificate or notice from Borrower or any Lender stating the existence
of Default or Event of Default or that any conditions to the making of such
Swingline Loan have not been satisfied.

         Section 2.2.3. SWINGLINE NOTE. On the Closing Date, Borrower shall
issue to the Administrative Agent a promissory note executed by Borrower in
substantially the form attached hereto as EXHIBIT D with all blanks
appropriately completed in conformity with this Agreement (the "Swingline
Note"). The Swingline Note shall evidence the obligation of Borrower to repay to
the Administrative Agent all Swingline Loans by the Administrative Agent to
Borrower. The Swingline Note shall (i) be payable to the Administrative Agent or
its registered assigns, (ii) be dated as of the Closing Date, (iii) be in a
stated principal amount equal to the Swingline Commitment, (iv) be payable in
the principal amount of the Swingline Loans evidenced thereby, (v) mature on the
Revolving Credit Termination Date, (vi) bear interest as provided in Section
2.4.4. hereof, (vii) be subject to voluntary prepayments as provided in Section
2.6.7. hereof and mandatory prepayments as provided in Section 2.6.8. hereof and
(viii) be entitled to the benefit of this Agreement and the Other Documents, and
all security granted or provided to the Administrative Agent for the ratable
benefit of the Lenders thereunder. The Administrative Agent shall record on its
internal records the amount of each Swingline Loan made by it and each payment
received by it in respect thereof and will prior to any transfer or assignment
of the Swingline Note endorse on the reverse side thereof the outstanding
principal amount of the Swingline Loan evidenced thereby; provided, however,
that the Administrative Agent's failure to make any such record or endorsement
shall not affect Borrower's obligations in respect thereof.

         Section 2.2.4. MANDATORY BORROWINGS. On any Business Day, the
Administrative Agent may, in its sole discretion, and, in any event, upon the
day which is seven (7) days after the borrowing of a Swingline Loan (or if such
day is not a Business Day, the next succeeding Business Day) shall provide
notice (which notice shall be deemed to have been automatically provided upon
the occurrence of a Default or Event of Default under Section 11.1.(g) or
11.1.(h)) to the Lenders having Revolving Loan Commitments that all outstanding
Swingline Loans shall be repaid pursuant to Revolving Loans to be made by such
Lenders as Base Rate Loans on the immediately succeeding Business Day (such
Revolving Loans, a "Mandatory Borrowing") pro 


<PAGE>
                                       32


rata based upon each such Lender's Revolving Loan Commitment Percentage, and the
proceeds of such Revolving Loans shall be applied directly to repay the
Administrative Agent for such outstanding Swingline Loans. Each Lender with a
Revolving Loan Commitment hereby irrevocably agrees to make Base Rate Loans upon
one (1) Business Day's notice pursuant to each Mandatory Borrowing in the amount
and in the manner provided in the foregoing sentence and on the date specified
by the Administrative Agent notwithstanding (i) that the amount of the Mandatory
Borrowing may not comply with the minimum borrowing amount otherwise required
under this Agreement, (ii) whether any of the conditions precedent in Section 6
of this Agreement shall have been satisfied, (iii) whether a Default or Event of
Default shall have occurred and be continuing, (iv) the date of such Mandatory
Borrowing and (v) any reduction in the Total Revolving Loan Commitment Amount
after such Swingline Loans were made. In the event that any Mandatory Borrowing
cannot be made as set forth above for any reason, including, without limitation,
the commencement of a proceeding under the Bankruptcy Code with respect to
Borrower), each Lender with a Revolving Loan Commitment (other than the
Administrative Agent) hereby agrees that it shall forthwith purchase from the
Administrative Agent (without recourse or warranty) an assignment of such
outstanding Swingline Loans as shall be necessary to cause such Lenders to share
in such Swingline Loans ratably based upon their respective Revolving Loan
Commitment Percentages; provided, however, that all interest payable on the
Swingline Loans shall be for the account of the Administrative Agent until the
effective date of the purchase of each respective assignment and, to the extent
attributable to the purchased assignment, shall be payable to the Lender
purchasing the same from and after such effective date.

         Section 2.3. THE TERM LOANS.

         Section 2.3.1. THE LOANS. Upon the execution of this Agreement, and so
long as no Default or Event of Default has occurred and is continuing, or would
occur as a result thereof, and all conditions precedent to the making of any
Extension of Credit have been satisfied, each Lender with a Term Loan Commitment
severally agrees to make a term loan (each a "Term Loan" and, collectively, the
"Term Loans") to Borrower on the Closing Date. The Term Loan of each such Lender
shall be made in dollars and be in that amount which is equal to such Lender's
Term Loan Commitment on the Closing Date. The Term Loans made under this
Agreement may not be reborrowed if repaid.

         Section 2.3.2. TERM NOTE. On the Closing Date, Borrower shall issue to
each of the Lenders with a Term Loan Commitment a promissory note executed by
Borrower in substantially the form attached hereto as EXHIBIT E with all blanks
appropriately completed in conformity with this Agreement (each a "Term Note"
and, collectively, the "Term Notes"). The Term Notes shall evidence the
obligation of Borrower to repay to the Lender to which it is issued the Term
Loan made by such Lender to Borrower on account of such Lender's Term Loan
Commitment. Each Term Note shall (i) be payable to the Lender to which it is
issued or its registered assigns, (ii) be dated as of the Closing Date, (iii) be
in a stated principal amount equal to the Term Loan Commitment of such Lender,
(iv) be payable in Dollars in the outstanding principal amount of the Term Loans
evidenced thereby, (v) mature on the Maturity Date, (vi) bear interest as
provided in Section 2.4.4. hereof, (vii) be subject to voluntary prepayments as
provided in Section 2.6.7. 


<PAGE>
                                       33


hereof and mandatory prepayments as provided in Section 2.6.8. hereof and (viii)
be entitled to the benefit of this Agreement and the Other Documents, and all
security granted or provided to the Agent for the ratable benefit of the Lenders
thereunder. The Adminisitrative Agent shall record each Term Loan in the Loan
Account and each Lender shall record on its internal records the amount of the
Term Loan made by it and each payment received by it in respect thereof and will
prior to any transfer thereof endorse on the reverse side thereof the
outstanding principal amount of the Term Loan evidenced thereby; PROVIDED,
however, that such Lender's failure to make any such record or endorsement shall
not affect Borrower's obligations in respect thereof.

         Section 2.3.3. PAYMENT OF PRINCIPAL. The outstanding principal amount
of the Term Loans shall be paid in full on the Maturity Date.

         Section 2.3.4. USE OF PROCEEDS. The proceeds of the Term Loans shall be
used solely to provide liquidity to Borrower to effect a dividend or other
distribution to SSH, which dividend or other distribution shall be used solely
to indefeasibly retire in full certain subordinated indebtedness of SSH existing
under that certain Note Purchase Agreement dated as of April 15, 1997 by and
among SSH and and the noteholders specified therein.

         Section 2.4. INTEREST ON THE LOANS.

         Section 2.4.1. BASE RATE. Each adjustment in the Base Rate shall result
immediately, without notice or demand of any kind, in a new rate of interest
effective with respect to periods on and after the date of such adjustment. The
Base Rate is a base interest rate for loans making reference thereto and is not
necessarily the lowest rate at which any Lender may lend money. The Base Rate is
neither tied to any external rate of interest nor is it a rate charged by any
Lender to any particular class or category of customer. If the Base Rate shall
be discontinued or for any other reason not be available for determining the
rate of interest chargeable under this Agreement, then the Administrative Agent
(with the consent of the Required Lenders) shall select a substitute method of
determining the rate of interest chargeable under this Agreement and shall
notify Borrower of such selection, which method shall, in the Administrative
Agent's estimation, yield a rate of return to each Lender substantially
equivalent to the rate of return that such Lender would have expected to receive
if the Base Rate remained available for that purpose.

         Section 2.4.2. CONTINUATION OR CONVERSION OF LOANS. As long as no
Default or Event of Default shall have occurred and be continuing, Borrower may
continue or convert all or any part (in integral multiples of ONE HUNDRED
THOUSAND AND NO/100 DOLLARS ($100,000.00)) of any outstanding Loan as a Loan of
the same Type or into a Loan of any other Type provided for in this Agreement.
If Borrower wishes to continue or convert a Loan as aforesaid, Borrower shall
provide the Administrative Agent with written notice (or telephonic notice
promptly confirmed in writing) received at its Notice Office no later than 10:00
a.m. (Boston, Massachusetts time) on the date one (1) Business Day before the
day on which the requested Loan is to be continued as or converted to a Base
Rate Loan, and received no later than 10:00 a.m. (Boston, Massachusetts time) on
the date three (3) Business Days before the day on which the requested Loan is
to be continued as or converted to a Eurodollar Loan. Each such 


<PAGE>
                                       34


notice (a "Notice of Continuation or Conversion") shall, except as provided in
Section 2.4.6. hereof, be irrevocable, be in the form of EXHIBIT F attached
hereto and be appropriately completed to specify: (i) the amount of the Loan to
be continued or converted, (ii) the effective date of such continuation or
conversion which shall, in the case of a Eurodollar Loan, be the last day of the
Interest Period applicable thereto, (iii) the Type or Types of Loans to be
applicable thereto; and (iv) the duration of the Interest Period, if any
(subject to the provisions of the definition of Interest Period). The
Administrative Agent shall promptly give each Lender written notice (or
telephonic notice promptly confirmed in writing) of each requested continuation
or conversion of a Loan, such Lender's proportionate share thereof and such
other matters covered by the Notice of Conversion or Continuation. Borrower
hereby acknowledges and agrees that the Administrative Agent may, prior to the
receipt of written confirmation act without liability upon the basis of any
telephonic notice provided under this Section 2.4.2. believed by the
Administrative Agent, in good faith, to be from a Responsible Officer of
Borrower and Borrower hereby waives the right to dispute the Administrative
Agent's record of the terms of such telephonic notice.

         Section 2.4.3. DURATION OF INTEREST PERIODS.

                  (a) Subject to the provisions of the definition of Interest
Period, the duration of each Interest Period applicable to a Loan shall be as
specified in the applicable Notice; provided, however, that in the case of Term
Loans, the Interest Period for a Eurodollar Loan shall be one (1) month.

                  (b) If the Administrative Agent does not receive a Notice for
a Eurodollar Loan pursuant to subsection (a) above within the applicable time
limits specified therein, or if, when such notice must be given, a Default or
Event of Default shall have occurred and be continuing, Borrower shall be deemed
to have elected to convert such Loan in whole into a Base Rate Loan on the last
day of the then current Interest Period with respect thereto.

                  (c) Notwithstanding the foregoing, Borrower may not select an
Interest Period that would end, but for the provisions of the definition of
Interest Period, after the Maturity Date.

         Section 2.4.4. INTEREST RATES AND PAYMENTS OF INTEREST.

                  (a) Each Base Rate Loan shall bear interest on the outstanding
principal amount thereof at a rate per annum equal to the Base Rate in effect
from time to time plus the Base Rate Margin applicable thereto. Interest
accruing in respect of each Base Rate Loan shall be payable on the last day of
each month commencing August 31, 1998 and continuing until such Base Rate Loan
is due (whether at maturity, by reason of acceleration, prepayment or
otherwise). Interest accrued but unpaid under the Third Restated Credit
Agreement in respect of Base Rate Loans shall be paid on the Closing Date.


<PAGE>
                                       35


                  (b) Each Eurodollar Loan, including any Existing Loan which is
a Eurodollar Loan, shall bear interest on the outstanding principal amount
thereof, for each Interest Period applicable thereto, at a rate per annum equal
to the Adjusted Eurodollar Rate plus the Eurodollar Margin applicable thereto,
which interest shall be payable on the last day of each Interest Period (but, in
the case of Interest Periods having a duration of six (6) months or greater, if
available, at least quarterly) and when such Eurodollar Loan is due (whether at
maturity, by reason of acceleration or otherwise).

                  (c) Interest shall be computed daily on the basis of a year of
three hundred sixty (360) days and paid for the actual number of days elapsed
during each Interest Period. If the due date for any payment of principal is
extended by operation of law, interest shall be payable for such extended time.
If any payment required by this Agreement becomes due on a day that is not a
Business Day such payment may be made on the next succeeding Business Day
(subject to clause (i) of the definition of Interest Period), and such extension
shall be included in computing interest in connection with such payment.

         Section 2.4.5. INTEREST RATE MARGINS. The Base Rate Margin applicable
to Term Loans shall be 2.50% and the Eurodollar Margin applicable to Term Loans
shall be 4.10%. As of the Closing Date, the Base Rate Margin applicable to
Revolving Loans shall be 1.50% and the Eurodollar Margin applicable to Revolving
Loans shall be 2.75%. Commencing with the end of the first Fiscal Quarter
following the Closing Date and continuing on the last day of each succeeding
Fiscal Quarter, and as long as no Default or Event of Default shall have
occurred and be continuing, the Base Rate Margin and the Eurodollar Margin
applicable, in each case, to Revolving Loans shall be subject to change (each
such change, a "Margin Change") by reference to Borrower's Leverage Ratio as of
the last day of any such Fiscal Quarter as follows:

           LEVERAGE RATIO               BASE RATE MARGIN       EURODOLLAR MARGIN
                                          APPLICABLE TO          APPLICABLE TO

      Equal to or greater than                1.50%                  2.75%
   3.75 to 1.0 (or if a Default or
          Event of Default
             shall exist)

      Equal to or greater than                1.25%                  2.50%

                                       36


The calculation of the Leverage Ratio for purposes of a Margin Change shall be
reviewed and verified by the Administrative Agent, in its sole and absolute
discretion, by reference to the Financial Statements to be provided by Borrower
under Section 7.1. hereof. In making such calculation, and for purposes of the
determination of any Margin Change only, Consolidated EBITDA shall be calculated
on an annualized basis by reference to the most recent Fiscal Quarter then
ending multiplied by four (4). Each Margin Change shall be effective, including
with respect to Loans which are then outstanding, as of the date on which the
Financial Statements referred to in Section 7.1. hereof are provided to the
Administrative Agent (notwithstanding the fact that the calculation of the
Leverage Ratio associated with such Margin Change is reviewed and verified by
the Administrative Agent at a later date). The Administrative Agent shall review
and verify the Borrower's calculation of the Leverage Ratio no later than three
(3) Business Days after its receipt of such Financial Statements. The
Administrative Agent shall, as soon as practicable, promptly notify each Lender
of the occurrence of any Margin Change.

         Section 2.4.6. CHANGED CIRCUMSTANCES. In the event that (x) in the case
of clause (i) below, the Administrative Agent or (y) in the case of clause (ii)
below, any Lender, shall have determined in a commercially reasonable manner
(which determination shall, absent manifest error, be final and conclusive and
binding upon all parties hereto):

                  (i) on any date on which the Eurodollar Rate would otherwise
         be set the Administrative Agent shall have determined in good faith
         (which determination shall be final and conclusive) that adequate and
         fair means do not exist for ascertaining the Interbank Offered Rate, or

                  (ii) at any time such Lender shall have determined in good
         faith that:

                            (A) the making or continuation of or conversion of
         any Loan to a Eurodollar Loan has been made impracticable or unlawful
         by (1) the occurrence of a contingency that materially and adversely
         affect the interbank Eurodollar market or (2) compliance by such Lender
         in good faith with any Requirement of Law enacted after the date hereof
         or interpretation or change thereof after the date hereof by any
         Governmental Authority charged with the interpretation or
         administration thereof or with any request or directive of any such
         Governmental Authority (whether or not having the force of law); or

                            (B) the Adjusted Eurodollar Rate shall, after the
         date hereof, no longer represent the effective cost to such Lender for
         U.S. dollar deposits in the interbank Eurodollar market for deposits in
         which it regularly participates;

then, and in any such event, such Lender (or the Administrative Agent in the
case of clause (i) above) shall (x) within five (5) Business Days after any such
event and (y) within five (5) Business Days of the date on which such event no
longer exists give notice (in writing or by telephone confirmed in writing) to
Borrower and (except in the case of clause (i) above) to the Administrative
Agent of such determination (which notice the Administrative Agent shall



<PAGE>
                                       37


promptly transmit to the other Lenders). Thereafter, (x) in the case of clause
(i) above, Eurodollar Loans shall no longer be available until such time as the
Administrative Agent notifies Borrower and the Lenders that the circumstances
giving rise to such notice by the Administrative Agent no longer apply, and any
Notice given by Borrower with respect to Eurodollar Loans which have not yet
been incurred shall be deemed rescinded by Borrower and (y) in the case of
clause (ii) above, Borrower shall, as applicable, either (a) pay to such Lender,
upon written demand therefor (accompanied by the written notice referred to
below), any such additional amounts (in the form of an increased rate of, or a
different method of calculating, interest or otherwise as such Lender may
determine in its sole discretion) as shall be required to compensate such Lender
for any increased costs or reductions in amounts received or receivable under
this Agreement (a written notice as to the additional amounts owed to such
Lender showing the basis for the calculation thereof, submitted to Borrower by
such Lender, shall, absent manifest error, be final and conclusive and binding
upon all parties hereto) or (b), as promptly as possible, and, in any event,
with the time period required by law, either (A), if any affected Eurodollar
Loan has not yet been made, continued or converted, cancel any such Notice by
giving the Administrative Agent a telephonic notice (confirmed promptly in
writing) thereof on the same date that Borrower was notified by a Lender as
aforesaid or (B), if any affected Eurodollar Loan has been made, continued or
converted, upon at least three (3) Business Days' notice to the Administrative
Agent, require the affected Lender (and any other similarly affected Lender) to
convert each such affected Eurodollar Loan into a Base Rate Loan (which
conversion shall occur no later than the last day of the Interest Period then
applicable to such Eurodollar Loan (or such earlier date if required by any
Requirement of Law).

         Section 2.4.7. COMPENSATION. Borrower shall compensate each Lender,
promptly upon its written request (which request shall be accompanied by a
notice setting forth the basis for such compensation), for all reasonable
losses, expenses and liabilities (including, without limitation, any such loss,
expense or liability incurred by reason of the liquidation or reemployment of
deposits or other funds required by such Lender to fund its Eurodollar Loans but
excluding loss of anticipated profit with respect to any Eurodollar Loans) which
such Lender may sustain: (i) if for any reason (other than a default by the
Administrative Agent or such Lender) a Eurodollar Loan is not made, continued or
converted on the date specified therefor in a Notice (whether or not withdrawn
by Borrower or deemed withdrawn under Section 2.4.6. hereof), (ii) if any
repayment (including any voluntary or mandatory repayment under Sections 2.6.7.
and 2.6.8. hereof or as the result of the acceleration of the Loans) or
conversion of Eurodollar Loan occurs on a date which is not the last day of the
Interest Period applicable thereto, (iii) if any prepayment of any Eurodollar
Loans is not made on any date specified in a notice of prepayment given by
Borrower, (iv) as a consequence of (x) any other failure or default by Borrower
to repay Eurodollar Loans when required by this Agreement or (y) any election by
Borrower under Section 2.4.6. hereof. The calculation of all amounts payable to
a Lender under this Section 2.4.7. shall be made as though that Lender has
actually funded its relevant Eurodollar Loan through the purchase of a
Eurodollar deposit bearing interest at the Adjusted Eurodollar Rate in an amount
equal to the amount of such Eurodollar Loan, having a maturity comparable to the
relevant Interest Period and through the transfer of such Eurodollar deposit
from an offshore office of such Lender to a domestic office of such Lender;
provided, however, that each Lender may fund each of its Eurodollar Loans in any



<PAGE>
                                       38


manner which it elects in its sole and absolute discretion. It is further
understood and agreed by Borrower that if any repayment of Eurodollar Loans
pursuant to Sections 2.6.7. or 2.6.8. or any conversion of Eurodollar Loans
shall occur on a day which is not the last day of an Interest Period applicable
thereto, such repayment or conversion shall be accompanied by any amounts owing
to any Lender under this Section 2.4.7.

                                       39


Administrative Agent, the Documentation Agent, any Lender or their parent
holding company any other condition regarding this Agreement and the result of
any event referred to in the preceding clause (i) or (ii) above shall be to
increase the cost to the Administrative Agent, the Documentation Agent, any
Lender or such holding company of issuing, funding or maintaining any Extension
of Credit (which increase in cost shall be determined by the Administrative
Agent's, the Documentation Agent's or such Lender's reasonable allocation of the
aggregate of such cost increases resulting from such event), then, upon written
demand by the Administrative Agent, the Documentation Agent or any such Lender,
Borrower shall pay to the Administrative Agent, the Documentation Agent or such

regulation regarding capital adequacy, or any change therein, or any change
after the date hereof in the interpretation or administration thereof, or
compliance by the Administrative Agent, the Documentation Agent, any Lender or
their parent holding company with any requirement or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, except any such adoption or change or any such
compliance with a request or directive which applies or has been applied solely
to the Administrative Agent, the Documentation Agent, any such Lender or such
parent holding company by reason of events or conditions relating solely to the
Administrative Agent, the Documentation Agent or any such Lender, has the effect
of reducing the rate of return on the Administrative Agent's, the Documentation
Agent's, any Lender's or their parent holding company's capital as a consequence
of its commitment hereunder or to a level below that which the Administrative
Agent, the Documentation Agent, any such Lender or such holding company could
have achieved but for such adoption, change or compliance by an amount deemed by
the Administrative Agent, the Documentation Agent or any such Lender to be
material (for which reduction of the rate of return shall be determined by the
Administrative Agent's, the Documentation Agent's, any such Lender's or such
holding company's reasonable allocation of such reduction of the rate of return
resulting from such event) then, upon written demand by the Administrative
Agent, the Documentation Agent or any such Lender, Borrower shall pay to the
Administrative Agent, the Documentation Agent or such Lender, from time to time

Agent, the Documentation Agent or any such Lender for such reduction. A
certificate as to such increased cost incurred by the Administrative Agent, the
Documentation Agent or any such Lender as a result of any event mentioned in
this subsection (b), prepared in reasonable detail (which shall include the
method employed by the Administrative Agent, the Documentation Agent or any such
Lender in determining the allocation of such costs to Borrower) and otherwise in
accordance with this subsection (b) submitted by the Administrative Agent, the
Documentation Agent or any such Lender to Borrower, shall be conclusive
evidence, absent manifest error, as to the amount thereof.

                  (c) Amounts payable by Borrower pursuant to this Section
2.6.1. shall be payable within ten (10) Business Days of receipt by Borrower of
a certificate described in subsection (a) or (b) of this Section 2.6.1.

         Section 2.6.2. METHOD OF PAYMENT. All payments and prepayments of
principal and all payments of Fees and interest shall be made by Borrower to the

and clear of, and without any deduction or withholding for, any taxes or other
payments. Any payments which are made later than 12:00 noon (Boston,
Massachusetts time) shall be deemed to have been made on the next Business Day.
Whenever any payment to be made hereunder shall be stated to be due on a day
which is not a Business Day (unless otherwise provided herein), the due date
thereof shall be extended to the next succeeding Business Day and, with respect
to payments of principal, interest shall be payable during such extension as the
applicable rate in effect immediately prior to such extension of time.

         Section 2.6.3. TAXES. All payments by Borrower under this Agreement
shall be made without set-off, counterclaim or other claim or defense. Except as
otherwise provided herein, all payments by or on behalf of Borrower hereunder
shall be made free and clear of, and without deduction or withholding for, any
and all current or future taxes, levies, imposts, duties, fees, assessments or
other charges of any kind or nature now or hereinafter imposed by a Governmental
Authority with respect to any such payment but excluding, except as provided
below, (i) any tax imposed on or measured by the net income or net profits of
any Lender or transferee or assignee thereof (a "Transferee") pursuant to any
Requirement of Law, or (ii) or franchise taxes imposed on net income or in lieu
thereof on any Lender or Transferee or (iii) any tax imposed by reason of any
connection between the jurisdiction imposing such tax and any Lender or
Transferee (other than a connection arising solely by virtue of the making of
any Extension of Credit under this Agreement) and all interest, penalties or
similar liabilities (all such non-excluded taxes, levies, imposts, duties, fees,
assessments or other charges being referred to as "Taxes"). If any Taxes are
required to be withheld or deducted from any payment under this Agreement,
Borrower agrees to pay the full amount of such Taxes deducted to the relevant
Government Authority in accordance with applicable law, and the payments under
this Agreement shall be increased by such additional amounts as may be necessary
so that every payment under this Agreement, after required withholding or
deduction on account of any Taxes, will not be less 


<PAGE>
                                       41


than the amount otherwise required to be paid under this Agreement. Borrower
shall furnish to the Administrative Agent within thirty (30) days after the date
the payment of any Taxes is due certified copies of any tax receipts evidencing
such payment by Borrower. Borrower agrees to indemnify and hold harmless the
Administrative Agent, the Documentation Agent and each Lender, and reimburse the
Administrative Agent, the Documentation Agent and each Lender upon its written
request, for the amount of any Taxes specified in this Section 2.6.3. as are
paid by such Lender, the Administrative Agent or the Documentation Agent. A
certificate as to the amount of any such indemnification prepared by such
Lender, the Administrative Agent or the Documentation Agent shall, absent
manifest error, be final, conclusive and binding for all purposes.

         Section 2.6.4. WITHHOLDING TAX EXEMPTION. Each Lender which is not a
United States person (as such term is defined in Section 7701(a)(30) of the
Code) agrees to deliver to Borrower and the Administrative Agent on or prior to
the Closing Date (i) two complete executed copies of Internal Revenue Service
Form 4224 or Form 1001 (or successor forms thereto) certifying such Lender's
entitlement to an exemption from United States withholding tax with respect to
payment to be made under this Agreement or (ii) if the Lender is not a "bank"
within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either
Form 4224 or Form 1001, a certificate in a form approved by the Administrative
Agent and two complete executed copies of Internal Revenue Service Form W-8 (or
successor form thereto) certifying such Lender's entitlement to exemption from
such withholding. In addition, each Lender agrees to deliver to Borrower and the
Administrative Agent updates or replacements to the foregoing forms and
certificates from time to time when due to the lapse of time, the change in
circumstances or otherwise, any such form or certificate previously provided
under this Section 2.6.4. shall become obsolete or inaccurate. Each Lender
agrees to immediately notify Borrower and the Administrative Agent in the event
that it is unable to certify that it is entitled to an exemption from
withholding as aforesaid. Notwithstanding any provision of Section 2.6.3 or this
Section 2.6.4. to the contrary, Borrower shall be entitled, to the extent
required by any Requirement of Law, to deduct and withhold income or similar
taxes imposed by the United States (or any other Governmental Authority) from
interest, fees or other amounts payable hereunder for the account of any Lender
which is not a United States person (as defined above) for U.S. Federal income
tax purposes to the extent that such Lender has not provided to Borrower forms
establishing an exemption therefrom as aforesaid and Borrower shall not be
obligated to pay any amounts under this Section 2.6.4. hereof in respect of
income or withholding taxes imposed by the United States if any Lender has not
provided the forms required to be provided pursuant to this Section 2.6.4.
hereof or, in the case of a payment, other than interest, to a Lender to the
extent that any such forms do not establish a complete exemption from
withholding of such taxes.

         Section 2.6.5. LENDING OFFICES. Loans of each Type made by any Lender
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type. Each Lender agrees that, upon the occurrence of any event
giving rise to the operation of Section 2.4.6., 2.6.1. or 2.6.3. hereof with
respect to such Lender, it will, if requested by Borrower, use reasonable
efforts (subject to overall policy considerations of such Lender) to designate
another lending office for any Extension of Credit affected by such event;
provided that in the sole judgment of 


<PAGE>
                                       42


such Lender, such Lender and its lending office suffer no economic, legal or
regulatory disadvantage, with the object of avoiding the consequences of the
event giving rise to the operation of any of the foregoing Sections. Nothing in
this Section 2.6.5. shall affect or postpone any of the obligations of Borrower
or the rights of any Lender under said Sections 2.4.6., 2.6.1. or 2.6.3.

         Section 2.6.6. REPLACEMENT OF LENDERS. (x) If any Lender becomes a
Defaulting Lender, (y) upon the occurrence of any event giving rise to the
operation of Sections 2.4.6., 2.6.1. or 2.6.3. with respect to any Lender which
results in such Lender charging to Borrower increased costs in excess of those
being generally charged by the other Lenders or (z) in the case of a refusal by
a Lender to consent to a proposed change, waiver, discharge or termination with
respect to this Agreement which has been approved by the Required Lenders as
provided in Section 10.14. hereof Borrower shall have the right, if no Default
or Event of Default then exists or, in the case of clause (z) above, would exist
after giving effect to such replacement, to replace such Lender (the "Replaced
Lender") with one or more other lenders, none of whom shall constitute a
Defaulting Lender at the time of such replacement (collectively, the
"Replacement Lender") and each of whom shall be acceptable to the Administrative
Agent; provided that (i) at the time of any replacement pursuant to this Section
2.6.6., the Replacement Lender shall enter into an Assignment and Acceptance
pursuant to Section 13.1. (and with all fees payable pursuant to said Section
13.1 to be paid by the Replacement Lender) pursuant to which the Replacement
Lender shall acquire the Revolving Loan Commitment and/or Term Loan Commitment,
as applicable, and the Revolving Loans and/or Term Loan, as applicable, of the
Replaced Lender and, in connection therewith, shall pay to (x) the Replaced
Lender in respect thereof an amount equal to the sum of (A) an amount equal to
the principal of, and all accrued interest on, all outstanding Loans of the
Replaced Lender and (B) an amount equal to all accrued, but theretofore unpaid,
Fees owing to the Replaced Lender and (y) the Administrative Agent an amount
equal to such Replaced Lender's pro rata share of any Mandatory Borrowing to the
extent such amount was not theretofore funded by such Replaced Lender, and (ii)
all obligations of Borrower then owing to the Replaced Lender (other than those
specifically described in clause (i) above in respect of which the assignment
purchase price has been, or is concurrently being, paid, but including all
amounts, if any, owing under Section 2.4.6.) shall be paid in full to such
Replaced Lender concurrently with such replacement. Upon the execution of the
respective Assignment and Acceptance, the payment of amounts referred to in
clauses (i) and (ii) above, recordation of the assignment on the Register by the
Administrative Agent pursuant to Section 13.2. and, if so requested by the
Replacement Lender of the appropriate Note or Notes executed by Borrower, the
Replacement Lender shall become a Lender hereunder and the Replaced Lender shall
cease to constitute a Lender hereunder, except with respect to indemnification
provisions under this Agreement, which shall survive as to such Replaced Lender.

         Section 2.6.7. VOLUNTARY PREPAYMENTS. Borrower shall have the right to
prepay the Loans, in whole or in part, without penalty or premium except as
otherwise provided in this Agreement from time to time on the following terms
and conditions: (i) Borrower shall provide written notice to the Administrative
Agent at its Notice Office (or telephonic notice promptly confirmed in writing)
of its intent to prepay the Loans, the amount of such prepayment, whether 


<PAGE>

partial prepayment of any Eurodollar Loan shall reduce the remaining aggregate
outstanding principal amount of such Eurodollar Loan to an amount which is less
than the minimum borrowing amount applicable under this Agreement for Eurodollar
Loans. The Administrative Agent shall promptly notify each Lender of any such
intended prepayment. Upon receipt by the Administrative Agent, any such
prepayment shall be applied pro rata among the Loans of each of the Lenders
being prepaid; provided, however, that such prepayment shall not be applied to
any Loans of a Defaulting Lender, until such time as the proportion that such
Lender's Unused Revolving Loan Commitment or Unused Term Loan Commitment bears

applicable, is equal to the proportion that such Lender's Revolving Loan
Commitment or Term Loan Commitment bears to the Total Revolving Loan Commitment
Amount or Total Term Loan Commitment Amount, as applicable.

         Section 2.7.2. NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT.

                  (a) Unless the Administrative Agent shall have received notice
from a Lender prior to the date on which such Lender is to provide funds to the
Administrative Agent for a Loan under such Lender's Revolving Loan Commitment or
Term Loan Commitment, as the case may be, that such Lender will not make
available to the Administrative Agent such funds, the Administrative Agent may
assume that such Lender has made such funds available to the Administrative
Agent on such date, and the Administrative Agent, in its sole discretion, may,
but shall not be obligated to, in reliance upon such assumption, make available
to Borrower on such date a corresponding amount. If and to the extent such
Lender shall not have so made such funds 


<PAGE>
                                       45


available to the Administrative Agent, such Lender (a "Defaulting Lender")
agrees to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to Borrower until the date such amount is repaid
to the Administrative Agent, at the Federal Funds Effective Rate. If such Lender
shall repay to the Administrative Agent such corresponding amount, such amount
so repaid shall constitute such Lender's Loan under its Revolving Loan
Commitment or Term Loan Commitment, as the case may be, for purposes of this
Agreement. If such Lender does not pay such corresponding amount forthwith upon
the Administrative Agent's demand therefor, the Administrative Agent shall be
entitled to all interest earned thereon or Fees earned in respect thereof
through the date of the payment of any such amount by such Lender. A Defaulting
Lender (regardless of whether such Lender serves as the Administrative Agent)
shall be deemed to have assigned to the extent of the delinquency any and all
payments due to it from Borrower in respect of such Lender's Revolving Loan
Commitment or Term Loan Commitment, as the case may be, whether on account of
outstanding Loans, interest, fees or otherwise, to the remaining Non-Defaulting
Lenders for application to, and reduction of, their respective PRO RATA shares
of all outstanding Loans of the Class at issue. The Defaulting Lender hereby
authorizes the Administrative Agent to distribute such payments to the
Non-Defaulting Lenders of the Class at issue in proportion to their respective
PRO RATA shares of all outstanding Loans of such Class. A Defaulting Lender
shall be deemed to have satisfied in full a delinquency when and if, as a result
of application of the assigned payments to all outstanding Loans of the
Non-Defaulting Lenders of the Class at issue, the Lenders' respective PRO RATA
shares of all outstanding Loans of such Class have returned to those in effect
immediately prior to such delinquency and without giving effect to the
nonpayment causing such delinquency.

                  (b) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to the Lenders
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date, and the Administrative Agent in its
sole discretion may, but shall not be obligated to, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender. If and to the extent that the Borrower
shall not have so made such payment in full to the Administrative Agent, each
Lender shall repay to the Administrative Agent forthwith on demand, which shall
be made promptly after discovery thereof, such amount distributed to such Lender
together with interest thereon, for each day from the date such amount is
distributed to such Lender until the date such Lender repays such amount to the
Administrative Agent, at the Federal Funds Effective Rate.

                  (c) Nothing contained in this Section 2.7.2. shall be
construed to relieve any Lender of its obligation to make funds available to the
Administrative Agent under this Agreement except as otherwise expressly provided
herein, nor to relieve the Borrower of its obligations to make any payment when
due.

                  (d) The Administrative Agent shall have no obligation to remit
to the Lenders any amounts under this Agreement not actually collected from the
Borrower. In addition, in the 


<PAGE>
                                       46


event that any payment received by the Administrative Agent is rescinded or must
otherwise be restored or returned upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of the Borrower or upon the appointment of any
intervenor or conservator of, or trustee or similar official for, the Borrower
or any substantial part of its properties or assets, or otherwise, and if the
Administrative Agent paid any Lender its pro rata share of such payment, then
such Lender shall, on demand from the Administrative Agent, immediately pay to
the Administrative Agent an amount equal to such Lender's pro rata share of any
such payment which must be rescinded, restored or returned by the Administrative
Agent. Any such amount shall be paid no later than 3:00 p.m. (Boston,
Massachusetts time) on the Business Day following the date of demand for payment
by the Administrative Agent and shall bear interest at the rate and in the
manner set forth in Section 2.7.2.(b) hereof.

         Section 2.7.3. SHARING OF PAYMENTS, ETC. Borrower hereby agrees that,
in addition to (and without limitation of) any right of set-off, banker's lien
or counterclaim a Lender may have hereunder or otherwise, each Lender and Lender
Affiliate shall be entitled at its option, but subject to Section 12.3. hereof,
to offset balances held by it at any of its offices against any principal of or
interest on any Loans, or any fee or expense payable to the Administrative
Agent, the Documentation Agent or the Lenders that is not paid when due
(regardless of whether such balances are then due to Borrower), in which case it
shall promptly notify Borrower and the Administrative Agent thereof; PROVIDED,
that its failure to give such notice shall not affect the validity thereof. If a
Lender shall effect payment of any principal, interest, fee or expense under
this Agreement through the exercise of any right of set-off, banker's lien,
counterclaim or similar right, it shall, subject to Section 12.3. hereof, be
deemed to have purchased from each of the other Lenders participations in the
Loans of the Class to which any such payment shall have been effected made by
the other Lenders of such Class in such amounts, and make such other adjustments
from time to time as shall be equitable, to the end that the Lenders of such
Class shall share the benefit of such payment PRO RATA in accordance with the
respective amounts of unpaid principal of and interest on the Loans of such
Class made by each of them. To such end, the Lenders shall make appropriate
adjustments among themselves (by the resale of participations sold or otherwise)
if such payment is rescinded or must otherwise be restored. Borrower agrees that
any Lender so purchasing a participation in the Loans made by the other Lenders
may exercise all rights of set-off, banker's lien, counterclaim or similar
rights with respect to such participation as fully as if such Lender were a
direct holder of the such Loans in the amount of such participation. Nothing
contained herein shall require any Lender to exercise any such right or shall
affect the right of any Lender to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or obligation
of Borrower to such Lender.

                     SECTION 3. SECURITY FOR THE OBLIGATIONS

         Section 3.1. COLLATERAL DISCLOSURE LIST. Borrower shall deliver to the
Administrative Agent and the Documentation Agent on or prior to the Closing Date
a completed Collateral Disclosure List certified by a Responsible Officer.

         Section 3.2. SECURITY. The Obligations shall be secured by:

Assignment, respectively.

         Section 3.2.6. The guarantee of each Subsidiary of Borrower, including,
specifically Detect and Protective, pursuant to a Subsidiary Guarantee.

         Section 3.2.7. All properties and assets of each Subsidiary of Borrower
which has executed a Subsidiary Guarantee, including goods, accounts receivable,
inventory, contract rights, accounts, documents, instruments and chattel paper,
business and financial records and general intangible assets of each such
Subsidiary (including all Capital Stock of any Subsidiaries of any such
Subsidiary), and all proceeds thereof, as more particularly defined in or

provided, however, that the Security Documents executed and delivered by Detect
(other than the Escrow Agreement and the Negative Pledge Agreement) shall be
held in escrow by the Administrative Agent's legal counsel pursuant to the
Escrow Agreement and Detect shall continue to be bound by the terms and
conditions of the Negative Pledge Agreement.

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

<PAGE>
                                       48


Administrative Agent, the Documentation Agent or the Lenders shall not diminish

duly incorporated, validly existing and in good standing under the laws of its
respective jurisdiction of incorporation and is duly qualified in all other

performance of this Agreement, the Notes, the Other Documents and the
Transaction Documents, the consummation of the transactions herein and therein
contemplated, the fulfillment of and compliance with the terms and provisions

obligations of each Credit Party which is a party thereto, enforceable against

any of such Credit Party's properties or assets except to the extent that such
violation or breach could not reasonably be expected to have a Material Adverse
Effect.

         Section 4.5. PERMITS. Each Credit Party possesses all material permits,
authorizations, licenses, approvals, waivers and consents, without unusual

         Section 4.7. FINANCIAL STATEMENTS. Borrower has provided to the
Administrative Agent and the Documentation Agent the consolidated Financial
Statements of SSH dated as of December 31, 1997, and related footnotes, audited
and certified by Ernst & Young, LLP. Borrower has also provided to the
Administrative Agent and the Documentation Agent the internally prepared
consolidated Financial Statements of (i) Borrower and its Subsidiaries and (ii)
the Direct Marketing Program, each dated as of May 31, 1998, certified by a
Responsible Officer but subject, however, to normal, recurring year-end
adjustments that shall not in the aggregate be material in amount. All Financial
Statements of any Credit Party heretofore provided to the Administrative Agent
and the Documentation Agent present fairly the financial condition and results
of business operations of the Persons covered thereby for the periods indicated
in accordance with GAAP. Neither Alarmguard Holdings, Borrower nor any of their
Subsidiaries has any material direct or contingent liabilities, liabilities for
taxes, unusual commitments or unrealized or unanticipated losses not disclosed
in such Financial Statements. Since the date of the latest dated consolidated
balance sheet included in the Financial Statements specified in this Section
4.7., there has been no development or event which could reasonably be expected
to have a Material Adverse Effect and no Dividends have been declared or made to
stockholders, nor has any of its Capital Stock been purchased or acquired by any
Person in any manner nor has Alarmguard Holdings, SSH, Borrower or any of their
Subsidiaries made any Investment except as set forth on SCHEDULE 4.7 attached
hereto.

         Section 4.8. FINANCIAL FORECASTS. Borrower has provided to the
Administrative Agent and the Documentation Agent forecasted Financial Statements
together with appropriate supporting details and a statement of the underlying
assumptions, covering the five (5) year period commencing on January 1, 1998
(the "Forecasts"). The Forecasts have been prepared in good faith and have a
reasonable basis.

         Section 4.9. FINANCIAL INFORMATION. All written data, reports and
information which any Credit Party has supplied to the Administrative Agent, the
Documentation Agent or the Lenders or caused to be so supplied by a third party
on its behalf in connection with this Agreement, was, at the time so supplied,
when taken as a whole, true and accurate in all material respects on the date as
of which such information is dated or certified and not incomplete by omitting
to state any material fact necessary to make such information at such time in
light of the circumstances under which such information was provided.

         Section 4.10. BUSINESS RELATIONSHIPS. There exists no actual or, to any
Credit Party's knowledge threatened, termination, cancellation or limitation of,
or any modification or change in, the business relationship of any Credit Party
with any customer or group of customers, or with any supplier (other than in the
ordinary course of business where one supplier is replaced by another offering
terms which are no less favorable to such Credit Party) which could reasonably
be expected to have a Material Adverse Effect.

         Section 4.11. BROKERS. No broker or finder has brought about the
obtaining, making or closing of, and no broker's or finder's fees or commissions
will be payable by any Credit Party or its Affiliates to any Person in

                                       50


         Section 4.12. USE OF PROCEEDS. Borrower is not an "investment company,"
or a company "controlled by" an "investment company," as such terms are defined
in the Investment Company Act of 1940, as amended (14 U.S.C. ss.ss.80(a)(1) ET
SEQ.). No Extension of Credit, the application of the proceeds and repayment
thereof by Borrower or the performance of the transactions contemplated by this
Agreement will violate any provision of said Act, or any rule, regulation or
order issued by the Securities and Exchange Commission thereunder. The proceeds
of each Extension of Credit will be used only for the purposes set forth in this
Agreement. None of the proceeds of any Extension of Credit will be used, or have
been used, directly or indirectly, for the purpose of purchasing or carrying any
"margin stock" or for the purpose of reducing or retiring any Indebtedness which
was originally incurred to purchase or carry any "margin stock" or for any other
purpose which might constitute such Extension of Credit a "purpose credit"
within the meaning of said Regulation U or Regulation X of the Federal Reserve
Board. Borrower will not take, or permit any Person acting on its behalf to
take, any action which might cause this Agreement or any document or instrument
delivered pursuant hereto to violate any regulation of the Federal Reserve
Board.

         Section 4.13. STATUTORY COMPLIANCE. Each Credit Party is in compliance
with all material laws, ordinances, rules, regulations and orders of any
Governmental Authority applicable to it, its properties or assets or the
business conducted by it (excepting ERISA and Environmental Laws which are the
subject of other provisions of this Agreement), except where non-compliance
could not reasonably be expected to have a Material Adverse Effect.

         Section 4.14. COMMITMENTS. No Credit Party has any fixed, contingent or
other obligations to issue any of its Capital Stock except as set forth on
SCHEDULE 4.14. attached hereto.

         Section 4.15. EVENTS OF DEFAULT. No Default or Event of Default has
occurred and is continuing.

         Section 4.16. OTHER DEFAULTS. No Credit Party is in default in the
performance, observance or fulfillment of any Contractual Obligation which could
reasonably be expected to have a Material Adverse Effect.

         Section 4.17. TAXES. Each Credit Party has filed all tax returns and
reports required to be filed by it with any Governmental Authority and has paid
in full, or made adequate provisions or established adequate reserves in
accordance with GAAP for, the payment of all taxes, interest, penalties,
assessments or deficiencies shown to be due or claimed to be due on or in
respect to such tax returns and reports.

         Section 4.18. OWNERSHIP OF BORROWER. SSH is the holder of all of the
issued and outstanding shares of capital stock of Borrower, and no other Person
has any rights and/or claim to any issued or unissued shares of such capital
stock.

         Section 4.19. SOLVENCY. Both before and after giving effect to (a) any
Extension of Credit to be made on the Closing Date or such other date on which
any Extension of Credit requested hereunder is made, (b) the disbursement of the
proceeds of any such Extension of Credit pursuant to the instructions of
Borrower, (c) the other transactions contemplated by this Agreement and the
Other Documents and (d) the payment and accrual of costs and expenses incurred
in connection with the foregoing, each Credit Party is Solvent. No Credit Party
is contemplating either the filing of a petition by it under Bankruptcy Code or
any state bankruptcy or insolvency law or the liquidating of all or a major
portion of its properties and assets, and no Credit Party has any knowledge of
any Person contemplating the filing of any such petition against it. If the
proceeds of the Term Loans are to be used to pay a Dividend to SSH by Borrower,
then Borrower is legallyable to pay such a Dividend under applicable law.

         Section 4.20. BUSINESS NAME. Each of Borrower and its Subsidiaries
conducts its business solely through the names set forth on SCHEDULE 11 of the
Collateral Disclosure List, without the use of any trade name, or the
intervention of or through any other Person. Neither Borrower nor any of its
Subsidiaries has, except as set forth in the Collateral Disclosure List, during
the preceding five (5) years, conducted its business through any other name or
trade name or been the surviving corporation in a merger or consolidation or
acquired all or substantially all of the assets of any other Person.

         Section 4.21. AFFILIATE CONTRACTS. Except as otherwise provided in this
Agreement or as set forth on Schedule 4.21. hereof, all contracts and
transactions between any Credit Party and any Affiliate or Subsidiary of such
Credit Party have been executed or will be executed on such terms as would be
contained in an agreement executed at arms' length with an unrelated third
party.

         Section 4.22. CAPITALIZATION. The outstanding shares of Capital Stock
of each Credit Party which have been pledged to the Administrative Agent for the
ratable benefit of the Lenders under the Security Documents have been duly
issued and are fully paid and non-assessable.

         Section 4.23. LITIGATION. Except as set forth on SCHEDULE 4.23.
attached hereto, there are no actions, suits or proceedings by or before any
Governmental Authority or any arbitration or alternate dispute resolution
proceeding, pending or, to the knowledge of any Credit Party or any of its
officers, threatened, against any Credit Party or its properties and assets,
which if adversely determined, could reasonably be expected to have a Material
Adverse Effect.

         Section 4.24. TITLE TO PROPERTIES. Each of Borrower and its
Subsidiaries has good and marketable title to all of its properties and assets
as are reflected in the Financial Statements referred to in Section 4.7. (except
such properties, assets or rights as have been disposed of in the ordinary
course of business since the date thereof), free from all Encumbrances except
Permitted Encumbrances or those Encumbrances disclosed in SCHEDULE 4.24.
attached hereto, and, free from all defects of title that could reasonably be
expected to have a Material Adverse Effect. The properties, assets and rights of
Borrower and its Subsidiaries are sufficient to permit Borrower and such
Subsidiaries to conduct the business in which it is presently engaged. Borrower
and its 


<PAGE>
                                       52


Subsidiaries possess all trademarks, service marks, trade names, trade service
styles, copyrights and patents that may be necessary to own their properties and
assets, and to conduct their business as it is presently conducted or as
intended to be conducted hereafter, without any infringement or conflict with
the rights of any other Person or any violation of law which could reasonably be
expected to have a Material Adverse Effect.

         Section 4.25. LABOR RELATIONS. No Credit Party is a party to any
collective bargaining or other agreement with any union and there are no
material grievances, disputes or controversies with any union or other
organization of such Credit Party's employees, or threats of strikes, work
stoppages or demands by any union or such other organization.

         Section 4.26. CONTINGENT OBLIGATIONS. No Credit Party is a party to any
Guarantee or other similar type of agreement, and it has not offered its
endorsement to any Person which would in any way create a contingent liability
(except by endorsement of negotiable instruments payable at sight for deposit or
collection or similar banking transactions in the ordinary course of business).

         Section 4.27. SUBSIDIARIES. As of the date of this Agreement, all of
the Subsidiaries and Affiliates of Borrower are set forth on SCHEDULE 13 of the
Collateral Disclosure List. Borrower or a Subsidiary of Borrower is the owner
free and clear of all Encumbrances, of all of the issued and outstanding Capital
Stock of each Subsidiary. Neither Borrower nor any of its Subsidiaries is
engaged in any joint venture, partnership or other business arrangement with any
other Person except as described on said SCHEDULE 13.

         Section 4.28. ERISA. Each Credit Party and each member of the
Controlled Group have fulfilled their obligations under the minimum funding
standards of ERISA and the Code with respect to each Plan and are in substantial
compliance in all material respects with the applicable provisions of ERISA and
the Code, and have not incurred any liability to the PBGC or a Plan under Title
IV of ERISA except where non-compliance or liability could not reasonably be
expected to have a Material Adverse Effect; and no Prohibited Transaction or
Reportable Event has occurred with respect to any Plan.

         Section 4.29. ENVIRONMENTAL PROTECTION. Except as set forth on SCHEDULE
4.29. attached hereto:

                  (a) The business operations of each of Borrower and its
Subsidiaries comply in all material respects with all Environmental Laws except
where non-compliance could not reasonably be expected to have a Material Adverse
Effect.

                  (b) Neither Borrower nor any of its Subsidiaries has received
(i) any notice or claim to the effect that it is or may be liable to any Person
as a result of the Release or threatened Release of any Hazardous Materials or
(ii) any letter or request for information under CERCLA or any other
Environmental Laws, and, to the best of Borrower's or any such Subsidiaries'
actual knowledge, based upon reasonable investigation, the business operations
of Borrower and such 


<PAGE>
                                       53


Subsidiaries are not the subject of any investigation by any Governmental
Authority evaluating whether any remedial action is needed to respond to a
Release or threatened Release of any Hazardous Material or claim, or threatened
lawsuit or claim arising under or related to any Environmental Law except, in
each case, where non-compliance could not reasonably be expected to have a
Material Adverse Effect.

                  (c) Borrower, its Subsidiaries and their properties, assets
and operations are not subject to any outstanding written order or agreement
with any Governmental Authority or private party respecting any Environmental
Laws except for any such written order or agreement which could not reasonably
be expected to have a Material Adverse Effect.

                  (d) Neither Borrower nor any of its Subsidiaries has filed any
notice under any Environmental Law indicating past or present treatment or
disposal of Hazardous Materials, and none of the operations of Borrower or any
such Subsidiaries involve the generation, transportation, treatment, storage or
disposal of Hazardous Materials except where such activity could not reasonably
be expected to have a Material Adverse Effect.

                  (e) To the best of Borrower's and its Subsidiaries' actual
knowledge, based upon reasonable investigation, no Hazardous Material exists on,
under or about any of the properties or assets of Borrower or any such
Subsidiaries, real or personal, in a manner that is likely to give rise to any
claim or suit against Borrower or any such Subsidiaries, and neither Borrower
nor any Subsidiary of Borrower has filed any notice or report of a Release of
any Hazardous Materials that could give rise to any such claim or suit against
Borrower except, in each case, where such claim or suit or filing could not
reasonably be expected to have a Material Adverse Effect.

         Section 4.30. INVESTMENTS. Except as set forth on SCHEDULE 4.30.,
attached hereto no Credit Party has an Investment in any Person other than
existing Investments in Subsidiaries and Qualified Investments.

         Section 4.31. SECURITY DOCUMENTS.

                  (a) The provisions of each Security Document are effective to
create in favor of the Administrative Agent for the ratable benefit of the
Lenders, a legal, valid and enforceable lien or security interest in all right,
title and interest of the Credit Party which is a party thereto in the
Collateral described therein.

                  (b) (i) When UCC financing statements, assignment and/or
amendments have been filed in the offices in the jurisdictions listed in
SCHEDULE 3 of the Collateral Disclosure List, the Borrower Security Agreement
and each Subsidiary Security Agreement, as applicable, shall constitute a fully
perfected first lien on, and security interest in, all right, title and interest
of the applicable Credit Party in the Collateral described therein, which can be
perfected by such filing.


<PAGE>
                                       54


                           (ii) When certificates representing the Pledged Stock
(as such term is defined in the Borrower Pledge Agreement) are delivered to the
Administrative Agent, together with stock powers endorsed in blank by a duly
authorized officer of Borrower, the Borrower Pledge Agreement shall constitute a
fully perfected first lien on, and security interest in, all right, title and
interest of Borrower in the Collateral described therein.

                           (iii) When certificates representing the Pledged
Stock (as such term is defined in the SSH Pledge Agreement) are delivered to the
Administrative Agent, together with stock powers endorsed in blank by a duly
authorized officer of SSH, the SSH Pledge Agreement shall constitute a fully
perfected first lien on, and security interest in, all right, title and interest
of SSH in the Collateral described therein.

                           (iv) When certificates representing the Pledged Stock
(as such term is defined in the Alarmguard Holdings Pledge Agreement) are
delivered to the Administrative Agent, together with stock powers endorsed in
blank by a duly authorized officer of Alarmguard Holdings, the Alarmguard
Holdings Pledge Agreement shall constitute a fully perfected first lien on, and

Agent or the Documentation Agent receives such a "Notice of Default" or in the
event of any nonpayment of principal or interest on the Loans, the
Administrative Agent and the Documentation Agent, as applicable, shall give
notice thereof to the Lenders and the Administrative Agent shall take such

penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Administrative Agent in its capacity as the Administrative Agent, as
applicable, under this Agreement in any way relating to or arising out of this
Agreement or any of the Other Documents or any other document contemplated

and all liability and expense that may be incurred by it by reason of taking or
continuing to take any such action.

written notice thereof to the Lenders and Borrower; PROVIDED, HOWEVER, that such
resignation shall not be effective in the case of the Administrative Agent until
the appointment of a successor Administrative Agent as provided for herein. Upon
any such resignation, the Lenders shall have the right, upon consultation with
Borrower, to appoint a successor Administrative Agent or successor Documentation
Agent. Unless a Default or Event of Default shall have occurred and be
continuing, such successor Administrative Agent or successor Documentation Agent
shall be reasonably acceptable to Borrower. If no successor Administrative Agent
shall have been so appointed by the Lenders and shall have accepted such
appointment within thirty (30) days after the Administrative Agent's giving of
notice of resignation, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent, which shall be a Lender
or financial institution having total assets in excess of FIVE HUNDRED MILLION
AND NO/100 DOLLARS ($500,000,000.00). In addition, the Administrative Agent or
the Documentation Agent may be removed by the Required Lenders at any time on
not less than thirty (30) days prior written notice to the Administrative Agent,
the Documentation Agent and the Lenders, as applicable. Upon the acceptance of
any appointment as the Administrative Agent or the Documentation Agent hereunder
by a successor Administrative Agent or successor Documentation Agent, such
successor Administrative Agent or successor Documentation Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent or retiring Documentation Agent, and the
retiring Administrative Agent or retiring Documentation Agent shall be
discharged from its duties and obligations hereunder. After any retiring
Administrative Agent's or retiring Documentation Agent's resignation, the
provisions of this Agreement and the Other Documents shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by the
Administrative Agent or the Documentation Agent while it was acting as the
Administrative Agent or the Documentation Agent.

         Section 10.11. COOPERATION OF LENDERS. The Administrative Agent and the
Documentation Agent shall provide the other Lenders with such information and
documentation as such other Lender shall reasonably request relating to the
performance of its duties hereunder, including all information relative to the
outstanding balance of principal, interest and other sums owed to such other
Lenders by Borrower; and cooperate with the other Lenders with respect to any
and all collections and/or foreclosure procedures at any time commenced against

         Section 10.12. ACTIONS BY ADMINISTRATIVE AGENT. In case one or more
Events of Default have occurred and shall be continuing, and whether or not
acceleration of the Obligations shall have occurred, the Administrative Agent
shall, if (a) so requested by the Required Lenders and (b) the Required Lenders
have provided to the Administrative Agent such additional indemnities and
assurances against expenses and liabilities as the Administrative Agent may
reasonably request, proceed to enforce the provisions of any of the Other
Documents authorizing the sale or other disposition of all or any part of the
Collateral and exercise all or any such other legal and equitable and other
rights or remedies as it may have in respect of such Collateral. The Required
Lenders may direct the Administrative Agent in writing as to the method and the

or remedies as it may have in respect of such Collateral, the Lenders hereby
agreeing to indemnify and hold the Administrative Agent, harmless from all
liabilities incurred in respect of all actions taken or omitted in accordance
with such directions; PROVIDED, HOWEVER, that the Administrative Agent need not
comply with any such direction to the extent that the Administrative Agent
reasonably believes the Administrative Agent's compliance with such direction to
be unlawful or commercially unreasonable in any applicable jurisdiction. In any
event, the Lenders agree, as among themselves, that the Administrative Agent
shall not, without the consent or approval of the Required Lenders and subject
to Section 10.14. hereof, (i) make any sale or disposition of the Collateral,

preceding clause (B) are immediately replaced in full at such time through the
addition of new Lenders or the increase of the Commitments and/or outstanding
Loans of existing Lenders (who in each case must specifically consent thereto),

Lender shall promptly notify the Administrative Agent of the sale of such
participation. A transferor Lender shall have no right to vote as a Lender under
this Agreement or any of the Other Documents for purposes of granting consents
or waivers or for purposes of agreeing to amendments or modifications to this
Agreement or any of the Other Documents or for purposes of making requests to
the Administrative Agent pursuant to Section 10 hereof to the extent that such
participation is beneficially owned by Borrower or any Affiliate of Borrower,

the Other Documents be made without regard to the interest of such transferor

any Lender may at any time pledge all or any portion of its interest and rights
under this Agreement (including all or any portion of its Note) to any of the
twelve (12) Federal Reserve Banks organized under Section 4 of the Federal
Reserve Act. No such pledge or the enforcement thereof shall release the pledgor

obligations of Borrower or any other Credit Party to the Administrative Agent,

the Documentation Agent and the Lenders shall not be deemed to have waived any
of their rights and remedies with respect to the Obligations or the Collateral
unless such waiver be in writing. No delay or omission on the part of the
Administrative Agent, the Documentation Agent or the Lenders in exercising any
right or remedy shall operate as a waiver of such right or remedy or any other
right or remedy. A waiver on any one occasion shall not be construed as a bar to
any subsequent enforcement by the Administrative Agent, the Documentation Agent
or the Lenders. All rights and remedies of the Administrative Agent, the
Documentation Agent or the Lenders with respect to the Obligations or the
Collateral shall be cumulative and may be exercised singularly or concurrently.

CONNECTION WITH OR IN ANY WAY RELATED TO THE TRANSACTION OF WHICH THIS AGREEMENT
IS A PART AND/OR IN THE ENFORCEMENT BY THE ADMINISTRATIVE AGENT, THE
DOCUMENTATION AGENT OR THE LENDERS OF ANY OF THEIR RIGHTS AND REMEDIES HEREUNDER
OR UNDER APPLICABLE LAW. EACH CREDIT PARTY ACKNOWLEDGES THAT IT MAKES THIS
WAIVER KNOWINGLY, VOLUNTARILY AND ONLY AFTER CONSIDERATION OF THE RAMIFICATIONS

         Section 14.2.4. LIEN AND SETOFF. Regardless of the adequacy of any

Documentation Agent, the Lenders, or any Lender Affiliate to any Credit Party
(other than payroll and payroll tax deposit accounts) may, at any time and from
time to time after the occurrence of an Event of Default, without notice to any

Lender Affiliate against any and all obligations of the Credit Parties to the
Administrative Agent, the Documentation Agent, the Lenders or any Lender
Affiliate in such manner as the Administrative Agent, the Documentation Agent,
the Lenders or any Lender Affiliate in their sole and absolute discretion may
determine, and each Credit Party hereby grants to the Administrative Agent, the
Documentation Agent and the Lenders a continuing security interest in such
deposits, balances or other sums for the payment and performance of all such
obligations. The rights provided to the Administrative Agent, the Documentation
Agent, the Lenders and any Lender Affiliate in this Section 14.2.4. shall be in

Agent, the Documentation Agent, the Lenders, any Lender Affiliate or any Lender
Agents which may arise out of the relationship between Borrower and the
Administrative Agent, the Documentation Agent, the Lenders or any Lender
Affiliate prior to the Closing Date; and (ii) absolutely and unconditionally

         Section 14.19. INTERPRETATION AND CONSTRUCTION. The following rules
shall apply to the interpretation and construction of this Agreement, the Notes

<PAGE>
                                       99


construed as including all statutory provisions consolidating, amending or
replacing the statute to which reference is made and all regulations promulgated
pursuant to such statutes; (d) references to "writing" shall include printing,
photocopy, typing, lithography and other means of reproducing words in a
tangible, visible form; (e) the words "including", "includes" and "include"
shall be deemed to be followed by the words "without limitation"; (f) references
to the introductory paragraph, preliminary statements, articles, sections (or
subdivisions of sections), exhibits or schedules are to those of this Agreement
unless otherwise indicated; (g) references to agreements and other contractual
instruments shall be deemed to include all subsequent amendments and other
modifications to such instruments, but only to the extent that such amendments
and other modifications are permitted or not prohibited by the terms of this
Agreement; (h) references to Persons include their respective permitted
successors and assigns; and (i) "or" is not exclusive.

         Section 14.20. GAAP AND ACCOUNTING CHANGES. Unless otherwise
specifically provided herein, any accounting term used in the Agreement shall
have the meaning customarily given such term in accordance with GAAP, and all
financial computations thereunder shall be computed in accordance with GAAP
consistently applied. That certain items or computations are explicitly modified
by the phrase "in accordance with GAAP" shall in no way be construed to limit
the foregoing. If any "Accounting Changes" (as defined below) occur and such
changes result in a change in the calculation of the financial covenants,
standards or terms used in the Agreement or any of the Other Documents, then the
Credit Parties, the Administrative Agent, the Documentation Agent and the
Lenders agree to enter into negotiations in order to amend such provisions of
the Agreement so as to equitably reflect such Accounting Changes with the
desired result that the criteria for evaluating any Credit Party's and its
Subsidiaries' financial condition shall be the same after such Accounting
Changes as if such Accounting Changes had not been made. "Accounting Changes"
means (a) changes in accounting principles required by the promulgation of any
rule, regulation, pronouncement or opinion by the Financial Accounting Standards
Board of the American Institute of Certified Public Accountants (or successor
thereto or any agency with similar functions); (b) changes in accounting
principals concurred in by any Credit Party's certified public accountants; (c)
purchase accounting adjustments under A.P.B. 16 and/or 17 and EITF 88-16, and
the application of the accounting principles set forth in FASB 109, including
the establishment of reserves pursuant thereto and any subsequent reversal (in
whole or in part) of such reserves; and (d) the reversal of any reserves
established as a result of purchase accounting adjustments. All such adjustments
resulting from expenditures made subsequent to April 15, 1997 (including
capitalization of costs and expenses or payment of pre-Closing Date liabilities)
shall, except as otherwise provided in this Agreement, be treated as expenses in
the period the expenditures are made and deducted as part of the calculation of
Consolidated EBITDA in such period. If the Credit Parties, the Administrative
Agent, the Documentation Agent and the Lenders agree upon the required
amendments, then after appropriate amendments have been executed and the
underlying Accounting Change with respect thereto has been implemented, any
reference to GAAP contained in this Agreement or in any of the Other Documents
shall, only to the extent of such Accounting Change, refer to GAAP, consistently
applied after giving effect to the implementation of such Accounting Change. If
the Credit Parties, the Administrative Agent, the Documentation Agent and the
Lenders cannot agree upon the required amendments within thirty (30) days
following the date of implementation of any 


<PAGE>
                                      100


Accounting Change, then all Financial Statements delivered and all calculations
of financial covenants and other standards and terms in accordance with this
Agreement and the Other Documents shall be prepared, delivered and made without
regard to the underlying Accounting Change.
