                    compliance  certificate,  in form and substance  approved by
                    Secured Party,  furnished by the Debtor), a Default or Event

                    Acquisition(s) shall not exceed $15 million.

               o    In the case of an acquisition of a non-domestic Consolidated

(iii)  the  value  of all  capital  stock  issued  by the  Debtor  or any of its
Consolidated  Subsidiaries in connection  with such  Acceptable  Acquisition and

determined  by the  Secured  Party on a  reasonable  basis,  on the basis of the
Debtor's projections.

including but not limited to, those set forth herein.

         6.3. INTEREST RATE. For each Advance, the Interest Rate shall be as set
forth in Section 7 herein and be evidenced by the Revolving Credit Note.

         6.4.  DEFAULT.  The Note shall  provide that upon the  happening of any
"Event of  Default"  hereunder  and/or  under  the  Transaction  Documents,  the

Credit Note, the Revolving Credit Note is subject to the express  condition that
at no time shall  Debtor be  obligated  to be  required  to pay  interest on the
principal  balance of the  Revolving  Credit Note at a rate which could  subject
Secured Party either to civil or criminal penalty as a result of being in excess

Note #1, and the Indebtedness evidenced by Note #1, shall be reduced only by the
last and final sums that Debtor  repays  with  respect to the  Revolving  Credit
Facility and shall not be reduced by any  intervening  repayments of Advances by
Secured Party until all Indebtedness under Note #2 has been repaid. All Advances
(including  readvances)  shall  first be deemed  borrowed  under Note #1 (to the

payment of the Indebtedness,  pursuant to Section 11.2. Whenever the outstanding
principal  balance of Advances  exceeds the  Borrowing  Capacity,  Debtor  shall
immediately pay to Secured Party the excess of the outstanding principal balance

         7.2. PROMISE TO PAY INTEREST.

                  (a) Debtor  promises to pay to Secured  Party  interest on the
outstanding  principal  of  Advances  from time to time unpaid at either (a) the
Variable  Rate  Option,  or (b) the LIBOR Rate  Option for the  Interest  Period
selected  by Debtor.  The amount of  principal  based upon the LIBOR Rate Option
shall be minimum  amounts of  $50,000.00  for the  Interest  Period  selected by
Debtor.  From the date of the occurrence of, and during the  continuance  of, an
Event of Default,  Debtor,  as additional  compensation to Secured Party for its
increased credit risk promises to pay interest on (i) the principal of Advances,
whether or not past due;  and (ii) past due  interest  and any other amount past

plus three percent per annum ("Default Rate" or "Default Rate of Interest").

                  (b) Interest  shall be paid (i) on the first day of each month
in arrears,  (ii) on the Termination Date, (iii) on acceleration of the time for
payment of the Indebtedness,  pursuant to Section 11.2, and (iv) on the date the
Indebtedness is paid in full.

                  (c) Any change in the interest rate resulting from a change in
the Prime Rate shall take  effect  simultaneously  with such change in the Prime
Rate.  Whether  the  Variable  Rate  Option or LIBOR  Rate  Option is in effect,
interest  shall be computed on the daily unpaid  principal  balance of Advances.
Interest  shall be calculated for each calendar day at 1/360th of the applicable
per annum rate which will result in an effective  per annum rate higher than the
rate specified herein. In no event shall the rate of interest exceed the maximum
rate  permitted by applicable  law. If Debtor pays to Secured Party  interest in
excess of the amount  permitted by applicable  law, such excess shall be applied
in reduction of the principal of Advances  under the Revolving  Credit  Facility
made  pursuant to this  Agreement,  and any  remaining  excess  interest,  after
application thereof to the principal of Advances, shall be refunded to Debtor.

                  (d) At Debtor's  option,  Debtor may elect to pay  interest on
one or more  Advances for one or more  Interest  Periods or for the term of this
Note, or any period of time, so long as such period is made available by Secured
Party and does not extend beyond the Term,  subject to the provisions  contained
herein,  by giving notice of such election to the Secured Party by 11:00 a.m. at
least  three (3)  Business  Days  before the first day of such  Advance.  If the
Debtor  does not elect an Interest  Rate Option for an Advance,  or prior to the
expiration  of an Interest  Period,  the Variable Rate Option shall be deemed to
have been chosen by Debtor.

                  (e) At the option of Debtor,  Debtor may elect to pay interest
on the  Indebtedness  herein  or  portion(s)  thereof,  in  minimum  amounts  of
$50,000.00  at the LIBOR Rate  Option for the  Interest  Period  selected by the
Debtor by giving  notice of such  election by the Secured Party by 11:00 a.m. at

                  (f) All written  notices of  Interest  Rate  Selection  and/or
Requests  for Advances  shall be  substantially  in the form  annexed  hereto as
Exhibit E, attached hereto and incorporated herein by this reference.

                  (g) At any time  while the  LIBOR  Rate  Option is in  effect,
Debtor agrees to pay to Secured  Party and hold Secured Party  harmless from any
loss or expense  ("breakage  fees" or "breakage  costs") which Secured Party may
sustain or incur as a consequence of such  prepayment.  Such breakage fees shall
equal the amount of the  Indebtedness  being prepaid,  multiplied by a per annum
interest rate equal to the  difference  between the then  applicable  Base LIBOR
Rate and the 360-day equivalent interest yield (hereinafter the "Bank Bid Rate")
reasonably  selected by the Secured  Party in its sole and absolute  discretion,
for an aggregate amount  comparable to the then remaining  principal  balance of
the  Indebtedness,  and with  maturities  comparable  to the  Rollover  Date (as
hereinafter  defined)  applicable to the principal  balance of the Indebtedness,
calculated  over a period of time from and including the date of prepayment  to,
but not including,  the Rollover Date applicable to the then remaining principal
balance of the Indebtedness being prepaid.  If the Base LIBOR Rate applicable to
the principal balance of the portion of the Indebtedness  being prepaid is equal
to or less than the Bank Bid Rate,  no LIBOR Rate breakage fee shall be due. The
term "Rollover Date" applicable to a particular LIBOR Interest Period shall mean
the last  day of  LIBOR  Interest  Period.  The  Secured  Party  shall  submit a
certificate to the Debtor  setting forth in reasonable  detail the amount of the
breakage costs, which certificate shall be conclusive in the absence of manifest
error.  The breakage costs shall also apply to prepayments  due as a result of a
default.  There shall be no breakage  costs for any portion of the  indebtedness
being prepaid bearing interest at the Variable Rate Option.

                  (h) At any time while the LIBOR Rate Option is in effect,  the
applicable LIBOR Interest Rate will equal the Adjusted LIBOR Rate plus the LIBOR
Margin,  based upon the ratio of Funded Debt to Cash Flow,  as described  herein
with respect to the applicable  Interest Period.  Each  determination of a LIBOR
Interest Rate shall be made by Secured Party 60 days after the end of Borrower's
first, second and third fiscal quarters, and 120 days after the end of Borrowers
fiscal year end (provided however that the financial  statements  required to be
delivered to Secured Party has in fact been timely delivered, with time being of
the  essence),  and shall be  conclusive  and  binding  upon the  Debtor  absent
manifest  error.  Secured Party will adjust the LIBOR Margin,  and the resulting
LIBOR Interest Rate  quarterly,  with Funded Debt to Cash Flow tested by Secured
Party  quarterly  based upon a rolling  four quarter  ratio of "Funded  Debt" to
"Cash Flow" of the Debtor and its Consolidated Subsidiaries, as follows:

        "Funded Debt" to "Cash Flow"            "LIBOR Margin"
        ----------------------------            --------------
                  < 5:1                             1.25%
                  > 5:1                             1.50%
                  -

Secured  Party will make its  determination  of the LIBOR  Margin based upon the
quarterly  and/or annual financial  statements,  10-K's and 10-Q's of the Debtor
and its  Consolidated  Subsidiaries  required to be submitted  to Secured  Party
pursuant to the terms of Section 9.1.  hereinbelow.  If the Debtor shall fail to

                                       21
<PAGE>

deliver to Secured Party the required  financial  statements  and other required
reports,  the Revolving Credit Facility shall bear interest at the Variable Rate
Option until such  statements and reports have been  received,  provided that no
Event of Default has occurred and is continuing, in which case, the Default Rate
shall apply.

         7.3.  PROMISE TO PAY FEES.  Debtor  promises  to pay to  Secured  Party
monthly,  on the first day of each  calendar  month,  an unused fee equal to one
quarter of one  percent  (.25%) of  $25,000,000.00  less the  aggregate  average
principal  balance of all Advances  outstanding  during the calendar  month just
ended under the Revolving Credit  Facility,  calculated for each calendar day at
1/360th of the  applicable  per annum rate which will result in an effective per

recognized in any such Securities Account or Deposit Account,  or any Securities
Account  holding  Collateral  or in  respect  of any other  Investment  Property
constituting  Collateral,  shall be reported to the Internal Revenue Service and

principal  of the  Indebtedness  then  outstanding  to be  immediately  due  and
payable,  together  with all interest  thereon and costs and  expenses  accruing
under the Transaction Documents. Upon such declaration,  any obligations Secured
Party may have hereunder shall be immediately  cancelled,  and the  Indebtedness
then outstanding shall become immediately due and payable without  presentation,
demand, or further notice of any kind to Debtor.

                  (b) Upon the  happening of one or more Events of Default under
Section  11.1(e) or 11.1(f),  Secured  Party's  obligations  hereunder  shall be
cancelled immediately,  automatically,  and without notice, and the Indebtedness
then outstanding shall become immediately due and payable without  presentation,
demand, or notice of any kind to the Debtor.

12. SECURED PARTY'S RIGHTS AND REMEDIES.

         12.1.  GENERALLY.  Secured  Party's rights and remedies with respect to
the  Collateral,  in addition to those  rights  granted  herein and in any other
agreement between Debtor and Secured Party now or hereafter in effect,  shall be
those of a secured party under the Uniform  Commercial  Code as in effect in the
State and under any other applicable law.

         12.2. INTENTIONALLY DELETED PRIOR TO EXECUTION.

         12.3.  POSSESSION  OF  COLLATERAL.  Whenever  Secured  Party  may  take
possession of the Collateral,  pursuant to Section 12.1,  Secured Party may take
possession of the Collateral on Debtor's  premises or may remove the Collateral,
or any part thereof,  to such other places as the Secured Party may, in its sole
discretion,  determine. If requested by Secured Party, Debtor shall assemble the
Collateral and deliver it to Secured Party at such place as may be designated by
Secured Party.

         12.4.  COLLECTION OF  RECEIVABLES.  Upon the  occurrence of an Event of
Default  or an  event  which  with  notice  or lapse  of  time,  or both,  would
constitute an Event of Default,  Secured Party may demand,  collect, and sue for
all monies and  proceeds  due, or to become due, on the  Receivables  (in either
Debtor's  or Secured  Party's  name at the  latter's  option)  with the right to
enforce,  compromise,  settle,  or discharge any or all Receivables.  If Secured
Party  takes  any  action  contemplated  by this  Section  with  respect  to any
Receivable, Debtor shall not exercise any right that Debtor would otherwise have
had to take such action with respect to such Receivable.

         12.5. INTENTIONALLY DELETED PRIOR TO EXECUTION

         12.6. LICENSE TO USE PATENTS, TRADEMARKS AND TRADENAMES.  Debtor grants
to Secured Party a royalty-free license to use any and all patents,  trademarks,
and  tradenames  now or  hereafter  owned by, or  licensed  to,  Debtor  for the
purposes of manufacturing  and disposing of Inventory after the occurrence of an
Event of Default. All Inventory shall at least meet quality standards maintained
by Debtor prior to such Event of Default.

13.      MISCELLANEOUS.

         13.1.  PERFECTING THE SECURITY  INTEREST;  PROTECTING  THE  COLLATERAL.
Debtor  hereby  authorizes  Secured  Party  to file  such  financing  statements
relating to the Collateral  without Debtor's  signature thereon as Secured Party
may deem  appropriate,  and appoints Secured Party as Debtor's  attorney-in-fact
(without  requiring  Secured Party) to execute any such  financing  statement or
statements  in Debtor's  name and to perform all other acts which  Secured Party
deems  appropriate to perfect and continue the Security Interest and to protect,
preserve, and realize upon the Collateral.

         13.2.  PERFORMANCE OF DEBTOR'S DUTIES. Upon Debtor's failure to perform
any  of  its  duties  under  the  Transaction  Documents,   including,   without

                                       37
<PAGE>

limitation,  the duty to obtain insurance as specified in Section 9.11,  Secured
Party may, but shall not be obligated to, perform any or all such duties.

         13.3.  NOTICE OF SALE.  Without in any way requiring notice to be given
in the following manner, Debtor agrees that any notice by Secured Party of sale,
disposition,  or other intended  action  hereunder,  or in connection  herewith,
whether  required  by the Uniform  Commercial  Code as in effect in the State or
otherwise, shall constitute reasonable notice to Debtor if such notice is mailed
by regular or certified mail,  postage prepaid,  at least five (5) days prior to
such action,  to Debtor's  address or addresses  specified above or to any other
address which Debtor has specified in writing to Secured Party as the address to
which notices hereunder shall be given to Debtor.

         13.4.  WAIVER BY SECURED PARTY. No course of dealing between Debtor and
Secured Party and no delay or omission by Secured Party in exercising  any right
or remedy under the  Transaction  Documents or with respect to any  Indebtedness
shall operate as a waiver thereof or of any other right or remedy, and no single
or partial exercise thereof shall preclude any other or further exercise thereof
or the exercise of any other right or remedy. All rights and remedies of Secured
Party are cumulative.

         13.5. WAIVER BY DEBTOR. Secured Party shall have no obligation to take,
and Debtor shall have the sole  responsibility  for taking, any and all steps to
preserve  rights  against  any and all  Account  Debtors and against any and all
prior  parties to any note,  Chattel  Paper,  draft,  trade  acceptance or other
instrument for the payment of money covered by the Security Interest, whether or
not in Secured  Party's  possession.  Secured Party shall not be  responsible to
Debtor for loss or damage  resulting from Secured Party's failure to enforce any
Receivables or to collect any moneys due, or to become due,  thereunder or other
Proceeds constituting  Collateral hereunder.  Debtor waives protest of any note,
check,  draft,  trade  acceptance,  or other instrument for the payment of money
constituting  Collateral at any time held by Secured Party on which Debtor is in
any way liable and waives  notice of any other  action  taken by Secured  Party,
including,  without  limitation,  notice of Secured Party's intent to accelerate
the Indebtedness or any part thereof.

         13.6.  SETOFF.  Without  limiting  any other  right of  Secured  Party,
whenever  Secured  Party  has  the  right  to  declare  any  Indebtedness  to be
immediately due and payable (whether or not it has so declared),  Secured Party,
at its sole  election,  may setoff against the  Indebtedness  any and all monies
then or thereafter  owed to Debtor by Secured Party in any capacity,  whether or
not the  Indebtedness or the obligation to pay such monies owed by Secured Party
is then due, and Secured Party shall be deemed to have  exercised  such right of
setoff  immediately at the time of such election even though any charge therefor
is made or entered on Secured Party's records subsequent thereto.

         13.7.  ASSIGNMENT.  The rights and benefits of Secured Party  hereunder
shall, if Secured Party so agrees,  inure to any party acquiring any interest in
the  Indebtedness  or any part thereof.  Prior to the  occurrence of an Event of
Default  hereunder,  Secured  Party  shall give  Debtor  ninety  (90) days prior
written  notice of an  assignment  in full of its interest in the  Indebtedness,
with the exception of  assignments  of its interest in the  Indebtedness  due to
acquisition, merger, consolidation, takeover or such other like activity.

                                       38
<PAGE>

         13.8. SUCCESSORS AND ASSIGNS. Secured Party and Debtor, as used herein,
shall  include the  successors or assigns of those  parties,  except that Debtor
shall not have the right to assign its rights hereunder or any interest herein.

         13.9. MODIFICATION.  No modification,  rescission,  waiver, release, or
amendment of any  provision of this  Agreement  shall be made,  except as may be
provided in a written  agreement signed by Debtor and a duly authorized  officer
of Secured Party.

         13.10.  COUNTERPARTS.  This  Agreement may be executed in any number of
counterparts, and by Secured Party and Debtor on separate counterparts,  each of
which,  when so executed and delivered,  shall be an original,  but all of which
shall together constitute one and the same Agreement.

         13.11.   GENERALLY  ACCEPTED  ACCOUNTING   PRINCIPLES.   Any  financial
calculation to be made, all financial statements and other financial information
to be  provided,  and all books and  records to be kept in  connection  with the
provision  of this  Agreement,  shall be in  accordance  with GAAP  consistently
applied during each interval and from interval to interval;  provided,  however,
that in the event changes in GAAP shall be mandated by the Financial  Accounting
Standards Board or any similar accounting body of comparable standing, or should
be  recommended by Debtor's  certified  public  accountants,  to the extent such
changes  would  affect  any  financial  calculations  to be made  in  connection
herewith,  such changes shall be  implemented in making such  calculations  only
from and after such date as Debtor and  Secured  Party shall have  amended  this
Agreement to the extent  necessary to reflect such changes in the  financial and
other covenants to which such calculations relate.

         13.12. INDEMNIFICATION.

                  (a) If after  receipt of any  payment of all,  or any part of,
the Indebtedness,  Secured Party is, for any reason, compelled to surrender such
payment to any person or entity because such payment is determined to be void or
voidable as a  preference,  an  impermissible  setoff,  or a diversion  of trust
funds, or for any other reason, the Transaction Documents shall continue in full
force and Debtor shall be liable,  and shall  indemnify  and hold Secured  Party
harmless  for, the amount of such payment  surrendered.  The  provisions of this
Section shall be and remain effective  notwithstanding any contrary action which
may have been taken by Secured Party in reliance upon such payment, and any such
contrary  action so taken shall be without  prejudice to Secured  Party's rights
under the  Transaction  Documents  and shall be deemed to have been  conditioned
upon such payment  having become final and  irrevocable.  The provisions of this
Section  13.12(a)  shall  survive  the  termination  of this  Agreement  and the
Transaction Documents.

                  (b)  Debtor  agrees to  indemnify,  defend  and hold  harmless
Secured  Party from,  and against,  any and all  liabilities,  claims,  damages,
penalties,  expenditures, losses, or charges, including, but not limited to, all
costs of investigation,  monitoring,  legal representations,  remedial response,
removal, restoration or permit acquisition,  which may now, or in the future, be
undertaken,  suffered, paid, awarded, assessed, or otherwise incurred by Secured

                                       39
<PAGE>

Party or any other person or entity as a result of the presence of,  Release of,
or  threatened  Release  of  Hazardous  Substances  on, in,  under,  or near the
property owned, leased or operated by Debtor or any Consolidated Subsidiary. The
liability of Debtor under the covenants of this Section  13.12(b) is not limited
by any exculpatory  provisions in this Agreement or any other documents securing
the Indebtedness and shall survive repayment of the Indebtedness or any transfer
or  termination  of this  Agreement  regardless of the means of such transfer or
termination. Debtor agrees that Secured Party shall not be liable in any way for
the  completeness  or accuracy of any  Environmental  Report or the  information
contained therein.  Debtor further agrees that Secured Party has no duty to warn
Debtor or any other person or entity about any actual or potential environmental
contamination  or other  problem that may have become  apparent,  or will become
apparent, to Secured Party.

                  (c) Debtor  agrees to pay,  indemnify,  and hold Secured Party
harmless  from,  and  against,  any and all  liabilities,  obligations,  losses,
damages, penalties, actions, judgments, suits, costs, expenses, or disbursements
of any kind or nature whatsoever  (including,  without  limitation,  counsel and
special  counsel  fees and  disbursements  in  connection  with any  litigation,
investigation,  hearing,  or  other  proceeding)  with  respect,  or in any  way
related, to the existence,  execution, delivery,  enforcement,  performance, and
administration of this Agreement and any other Transaction  Document (all of the
foregoing,  collectively, the "Indemnified Liabilities"). The agreements in this
Section 13.12(c) shall survive repayment of the Indebtedness.

         13.13. TERMINATION.

                   This  Agreement  is,  and is  intended  to be,  a  continuing
Agreement  and shall  remain in full  force and  effect for the Term and for any
renewal term, if any; provided,  however,  that Secured Party may terminate this
Agreement by giving  Debtor  notice to terminate in writing at least one hundred
twenty (120) days prior to the end of the Term  whereupon at the end of the Term
all Indebtedness shall be due and payable in full without presentation,  demand,
or  further  notice  of any  kind,  whether  or not  all or  any  part  of  such
Indebtedness  is  otherwise  due  and  payable  pursuant  to  the  agreement  or
instrument  evidencing  same.  Notwithstanding  the  above,  Secured  Party  may
terminate  this  Agreement  immediately  and without  further  notice (except as
specifically provided for herein or in the other Transaction Documents) upon the
occurrence of an uncured or unremedied  Event of Default  herein or under any of
the Transaction  Documents.  In addition, the one hundred twenty (120) day prior
notice provision  contained in this Section 13.13.  does not apply and shall not
be  enforceable  in the  event  that an  uncured  default  has  occurred  and is
continuing  under the Transaction  Documents with respect to payment  covenants,
bankruptcy  covenants  or  bankruptcy  events of  default,  financial  covenants
contained in Section 9.26. herein, the negative covenants  contained in Sections
10.11, 10.15 and 10.16 herein, the cross-default with other creditors covenants,
and the event of default  specified in Section 11.1.  (q).  Notwithstanding  the
foregoing  or anything in this  Agreement  or  elsewhere  to the  contrary,  the
Security  Interest,  Secured  Party's rights and remedies under the  Transaction
Documents  and  Debtor's  obligations  and  liabilities  under  the  Transaction
Documents,  shall survive any  termination of this Agreement and shall remain in
full force and effect until all of the Indebtedness  outstanding,  or contracted
or committed for (whether or not outstanding), before the receipt of such notice
by Secured Party, and any extensions or renewals thereof (whether made before or
after receipt of such notice),  together  with interest  accruing  thereon after

                                       40
<PAGE>

such notice,  shall be finally and irrevocably paid in full. No Collateral shall
be  released  or  financing  statement  terminated  until:  (i) such  final  and
irrevocable  payment in full of the  Indebtedness  as described in the preceding
sentence;  and (ii) Debtor and Secured Party execute a mutual  general  release,
subject to Section 13.12 of this Agreement,  in form and substance  satisfactory
to the Secured Party and Debtor and their counsel.

         13.14.  FURTHER  ASSURANCES.  From time to time, Debtor shall take such
action and  execute  and  deliver to Secured  Party such  additional  documents,
instruments,  certificates,  and  agreements  as  Secured  Party may  reasonably
request to effectuate the purposes of the Transaction Documents.

         13.15.  HEADINGS.  Article and Section  headings used in this Agreement
are  for  convenience  only  and  shall  not  affect  the  construction  of this
Agreement.

         13.16. CUMULATIVE SECURITY INTEREST, ETC. The execution and delivery of
this  Agreement  shall in no  manner  impair or affect  any other  security  (by
endorsement or otherwise) for payment or performance of the Indebtedness, and no
security  taken  hereafter  as  security  for  payment  or  performance  of  the
Indebtedness  shall  impair  in any  manner  or affect  this  Agreement,  or the
security  interest  granted  hereby,  all such  present  and  future  additional
security to be considered as cumulative security.

         13.17. SECURED PARTY'S DUTIES.  Without limiting any other provision of
this Agreement:  (a) the powers  conferred on Secured Party hereunder are solely
to protect  its  interests  and shall not impose any duty to  exercise  any such
powers; and (b) except as may be required by applicable law, Secured Party shall
not have any duty as to any  Collateral  or as to the  taking  of any  necessary
steps to preserve  rights against any parties or any other rights  pertaining to
any Collateral.

         13.18. NOTICE GENERALLY. All notices and other communications hereunder
shall be made by telegram, telex, electronic transmitter, overnight air courier,
or certified or registered mail, return receipt  requested,  and shall be deemed
to be received by the party to whom sent one Business Day after sending, if sent

Business Days after mailing,  if sent by certified or registered  mail. All such
notices and other  communications  to a party  hereto shall be addressed to such

attention of the Senior Vice President for  Operations  and Finance.  As of this
date the Senior Vice President for Operations and Finance is Kevin Buchel.

         13.19.  SEVERABILITY.  The provisions of this Agreement are independent
of, and separable from,  each other,  and no such provision shall be affected or
rendered  invalid or unenforceable by virtue of the fact that for any reason any
other such provision may be invalid or unenforceable in whole or in part. If any
provision of this Agreement is prohibited or unenforceable in any  jurisdiction,
such provision shall be ineffective in such  jurisdiction  only to the extent of
such prohibition or  unenforceability,  and such prohibition or unenforceability

                                       41
<PAGE>

shall not  invalidate  the  balance  of such  provision  to the extent it is not
prohibited  or  unenforceable  nor  render  prohibited  or  unenforceable   such
provision in any other jurisdiction.

         13.20.  INCONSISTENT  PROVISIONS.  The terms of this  Agreement and the
other  Transaction  Documents shall be cumulative except to the extent that they
are specifically  inconsistent  with each other, in which case the terms of this
Agreement shall prevail.

         13.21.  ENTIRE  AGREEMENT.  This  Agreement  and the other  Transaction
Documents constitute the entire agreement and understanding  between the parties
hereto with respect to the  transactions  contemplated  hereby and supersede all
prior  negotiations,  understandings,  and agreements  between such parties with
respect to such transactions,  including, without limitation, those expressed in
any commitment letter delivered by Secured Party to Debtor.

         13.22.  APPLICABLE LAW. THIS AGREEMENT,  AND THE TRANSACTIONS EVIDENCED
HEREBY,  SHALL BE GOVERNED BY, AND  CONSTRUED  UNDER,  THE INTERNAL  LAWS OF THE
STATE,  WITHOUT  REGARD TO  PRINCIPLES OF CONFLICTS OF LAW, AS THE SAME MAY FROM
TIME TO TIME BE IN EFFECT, INCLUDING, WITHOUT LIMITATION, THE UNIFORM COMMERCIAL
CODE AS IN EFFECT IN THE STATE.

         13.23. CONSENT TO JURISDICTION. DEBTOR AND SECURED PARTY AGREE THAT ANY
ACTION OR PROCEEDING TO ENFORCE,  OR ARISING OUT OF, THE  TRANSACTION  DOCUMENTS
MAY BE  COMMENCED  IN ANY COURT OF THE STATE IN ANY COUNTY,  OR IN THE  DISTRICT
COURT OF THE  UNITED  STATES  IN ANY  DISTRICT,  IN WHICH  SECURED  PARTY HAS AN
OFFICE,  AND DEBTOR WAIVES PERSONAL SERVICE OF PROCESS AND AGREES THAT A SUMMONS
AND  COMPLAINT  COMMENCING  AN ACTION OR  PROCEEDING  IN ANY SUCH COURT SHALL BE
PROPERLY SERVED AND SHALL CONFER  PERSONAL  JURISDICTION IF SERVED BY REGISTERED
OR CERTIFIED MAIL TO DEBTOR,  OR AS OTHERWISE  PROVIDED BY THE LAWS OF THE STATE
OR THE UNITED STATES.

         13.24.  JURY TRIAL WAIVER.  DEBTOR AND SECURED PARTY HEREBY  KNOWINGLY,
VOLUNTARILY,  AND  INTENTIONALLY  WAIVE  ANY  RIGHT TO TRIAL BY JURY  DEBTOR  OR
SECURED  PARTY MAY HAVE IN ANY ACTION OR  PROCEEDING,  IN LAW OR IN  EQUITY,  IN
CONNECTION WITH THE TRANSACTION  DOCUMENTS OR THE TRANSACTIONS  RELATED THERETO.
DEBTOR  REPRESENTS AND WARRANTS THAT NO REPRESENTATIVE OR AGENT OF SECURED PARTY
HAS  REPRESENTED,  EXPRESSLY OR  OTHERWISE,  THAT SECURED PARTY WILL NOT, IN THE
EVENT OF  LITIGATION,  SEEK TO ENFORCE THIS RIGHT TO JURY TRIAL  WAIVER.  DEBTOR
ACKNOWLEDGES  THAT SECURED  PARTY HAS BEEN INDUCED TO ENTER INTO THIS  AGREEMENT
BY, AMONG OTHER THINGS, THE PROVISIONS OF THIS SECTION 13.24.

Melville, New York  11747

Re:     Revolving  Credit  Note  #1  by  NAPCO  Security   Systems,   Inc.  (the
        "Borrower") to Marine Midland Bank, now known as HSBC Bank USA, National
        Association,  successor  by merger to HSBC  Bank USA  ("Lender")  in the
        aggregate  principal sum of up to $1,000,000.00,  dated May 12, 1997, as
        the same may be extended or otherwise  modified from time to time ("Note
        #1" or "Revolving Credit Note #1")

Ladies and Gentlemen:

        The undersigned hereby reaffirms and ratifies all the terms, conditions,
representations  and  covenants  contained in Note #1 and  certifies  that (i)no
default,  nor events which with notice and/or passage of time would constitute a
default,  has  occurred  and is  continuing  under  Note #1 or any of the  other
instruments  executed and  delivered  to evidence  and/or  secure the  revolving
credit facility or under any other note, loan or security agreement to which the
Borrower is a party, (ii) there are no offsets, defenses or counterclaims to the
Borrower's  obligations  under Note #1 and the other  Transaction  Documents and
(iii) the  Borrower  has not entered  into any  agreement  with  creditors  that
expressly or otherwise prohibit the Borrower from entering into any extension or
modification of Note #1 as of the date hereof.

        The undersigned  further  covenants and agrees that Lender has agreed to
extend the  Termination  Date pursuant to and in accordance with the amended and
restated  loan and  security  agreement  dated as of even  date  hereof,  by and
between the  Borrower  and Lender,  as may be amended,  extended,  or  otherwise
modified  or  restated  from  time  to  time  (the   "Agreement"  or  the  "Loan
Agreement").  Note #1 is governed by the terms of the Agreement,  with the terms
of the Agreement incorporated herein by this reference.

        Note # 1 continues to be secured by and the parties  hereto are entitled
to the benefits of that certain  Second  Mortgage and Security  Agreement in the
principal  amount  of  $1,000,000,  dated  as May 12,  1997,  as the same may be
