          ITEM 5.  OTHER EVENTS.
                   -------------

                    On May 7, 1999, American Eco Corporation, ("American
          Eco"), together with its principal subsidiaries (each, a
          "Borrower," and collectively, the "Borrowers") entered into a
          Credit Agreement with General Electric Capital Corporation, as
          lender and agent (the "Agent"), for any additional lenders from
          time to time under the Credit Agreement (the "Lenders").  The
          Credit Agreement provides for a revolving credit facility (the
          "Revolver") of up to $30 million, which includes a $2.5 million
          letter of credit subfacility.

                    The proceeds of the Revolver will be used by the
          Borrowers for working capital and other general corporate
          purposes, as well as for acquisitions meeting the criteria
          established in the Credit Agreement or as otherwise permitted by
          the Lenders.

                    Under the Revolver, each Borrower (or the Borrower
          group of which it is a member) may make borrowings based upon the
          sum of up to (a) 85% of its eligible accounts receivable (other
          than eligible incomplete cost plus contract accounts receivable);
          and (b) 50% of its eligible incomplete cost plus contract
          accounts receivable, in each case, less any reserves established
          by the Agent.  

                    The Revolver has a two-year term, subject to two
          automatic one year extensions at the mutual discretion of the
          Borrowers and the Lenders.  Borrowing under the Revolver by US
          Borrowers will accrue interest at a rate equal to 2% above the
          latest month-end 30-day commercial paper rate for high-grade
          unsecured notes sold through dealers by major corporations, in
          multiples of $1,000, as from time to time reported in The Wall
          Street Journal.  Borrowing under the Revolver by Canadian
          Borrowers will accrue interest at a rate equal to 2% above the
          rate of interest per annum determined by the Agent, from month to
          month, by reference to the average rate quoted on the Reuters
          Monitor Screen (Page CDOR) applicable to 30-day Canadian dollar
          bankers' acceptances.  Letters of credit issued pursuant to the
          Credit Agreement will be subject to a fee of 1% of the face
          amount thereof, plus any costs and expenses incurred by the
          Lenders in arranging for the issuance or guaranty of such letters
          of credit and any charges assessed by the issuing banks.

                    The obligations of the Borrowers under the Credit
          Agreement are secured by, among other things, (a) Guarantees
          entered into by American Eco and certain of its United States and
          Canadian subsidiaries; (b) Security Agreements entered into by
          American Eco and certain of its United States and Canadian
          subsidiaries of their receivables, inventory and general
          intangibles, and (c) Patent, Trademark and Copyright Security

         THIS CREDIT  AGREEMENT  ("Agreement"),  dated as of May 7, 1999,  among
each of the  corporations  listed on Schedule A hereto  (such  corporations  are
                                     ----------
sometimes  collectively  referred to herein as "Borrowers" and individually as a
                                                ---------
"Borrower"); the other Credit Parties signatory hereto; GENERAL ELECTRIC CAPITAL
 --------
CORPORATION,  a New York corporation (in its individual capacity, "GE Capital"),
for itself, as Lender, and as Agent for Lenders, and the other Lenders signatory
hereto from time to time.

                                    RECITALS
                                    --------

         WHEREAS,  Borrowers have requested that Lenders extend revolving credit
facilities to Borrowers of up to Thirty Million US Dollars  ($30,000,000) in the
aggregate to provide (a) working capital financing for Borrowers,  (b) funds for
other general  corporate  purposes of Borrowers;  and (c) funds for certain fees
and expenses in connection with the transactions  contemplated  hereby;  and for
these purposes,  Lenders are willing to make certain loans and other  extensions
of credit to  Borrowers of up to such amount upon the terms and  conditions  set
forth herein; and

         WHEREAS, Borrowers have agreed to secure all of their obligations under
the Loan Documents by granting to Agent, for the benefit of Agent and Lenders, a
security interest in and lien upon certain existing and after-acquired  personal
property; and

         WHEREAS,  American  Eco  Corporation,  an Ontario,  Canada  corporation
("Holdings")  and the direct or indirect  beneficial owner of all of the capital
stock or partnership  interests of Borrowers,  is willing to guaranty all of the
obligations of Borrowers to Agent and Lenders under the Loan Documents; and

         WHEREAS,  capitalized  terms  used in this  Agreement  shall  have  the
meanings ascribed to them in Annex A and, for purposes of this Agreement and the
other  Loan  Documents,  the  rules of  construction  set forth in Annex A shall
govern.  All  Annexes,  Disclosure  Schedules,  Exhibits  and other  attachments
(collectively,  "Appendices") hereto, or expressly identified to this Agreement,
are  incorporated  herein by reference,  and taken together with this Agreement,
shall  constitute but a single  agreement.  These Recitals shall be construed as
part of the Agreement.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants hereinafter contained,  and for other good and valuable consideration,
the parties hereto agree as follows:

1.       AMOUNT AND TERMS OF CREDIT

         1.1      Credit Facilities
                  -----------------

                  (a)      Revolving Credit Facility.
                           -------------------------

                           (i)      Subject to the terms and conditions hereof,
each Revolving Lender agrees to make available to Borrowers from time to time 
until the Commitment Termination Date


<PAGE>



its Pro Rata Share of advances  (each, a "Revolving  Credit  Advance").  The Pro
Rata Share of the Revolving  Loan of any Revolving  Lender shall not at any time
exceed its separate Revolving Loan Commitment. The obligations of each Revolving
Lender  hereunder  shall be  several  and not  joint.  The  aggregate  amount of
Revolving Credit Advances (calculated at the US Dollar Amount) outstanding shall
not  exceed  at any  time  the  lesser  of (A) the  Maximum  Amount  and (B) the
Aggregate  Borrowing Base, in each case, less the aggregate  amount of Letter of
Credit Obligations (calculated at the US Dollar Amount) outstanding at such time
("Borrowing  Availability").  Borrowing  Availability  may be further reduced by
Reserves  imposed by Agent in its  reasonable  credit  judgment.  Moreover,  the
Revolving Loan outstanding to any Borrower or Borrower Group shall not exceed at
any time that Borrower's or Borrower Group's respective separate Borrowing Base.
Until the Commitment  Termination  Date,  each  respective  Borrower or Borrower
Group,  as the case may be,  may from time to time  borrow,  repay and  reborrow
under this Section 1.1(a). Each Revolving Credit Advance shall be made on notice
by  Borrower  Representative  on behalf of the  applicable  Borrower or Borrower
Group, as the case may be, to one of the  representatives of Agent identified on
Disclosure Schedule 1.1 at the address specified thereon.  Those notices must be
given no later  than  11:00  a.m.(New  York  time)  on the  Business  Day of the
proposed  Revolving  Credit  Advance.  Each such notice (a "Notice of  Revolving
Credit  Advance")  must be given in writing (by telecopy or  overnight  courier)
substantially  in  the  form  of  Exhibit  1.1(a)(i),   and  shall  include  the
information  required  in such  Exhibit  and such  other  information  as may be
required by Agent.  Each  Revolving  Credit  Advance shall be made in US Dollars
except  that each  Revolving  Credit  Advance  to AEC  Funding  shall be made in
Canadian Dollars.

                           (ii)  Except  as  provided  in  Section  1.11,   each
Borrower shall execute and
deliver  to  each  Revolving  Lender  a note  to  evidence  the  Revolving  Loan
Commitment of that Revolving Lender.  Each note shall be in the principal amount
of the Revolving Loan Commitment of the applicable  Revolving Lender,  dated the
Closing  Date  and  substantially  in the  form of  Exhibit  1.1(a)(ii)  (each a
"Revolving Note" and, collectively,  the "Revolving Notes"). Each Revolving Note
shall  represent the obligation of the applicable  Borrower to pay the amount of
the applicable  Revolving  Lender's  Revolving Loan  Commitment or, if less, the
applicable  Revolving  Lender's Pro Rata Share of the aggregate unpaid principal
amount of all  Revolving  Credit  Advances to such  Borrower  or Borrower  Group
together with  interest  thereon as prescribed in Section 1.5. The entire unpaid
balance of the aggregate Revolving Loan and all other non-contingent Obligations
shall be immediately  due and payable in full in immediately  available funds on
the Commitment Termination Date.

                  (b)   Reliance   on   Notices;    Appointment    of   Borrower
                        --------------------------------------------------------
Representative.  Agent  shall  be  entitled  to rely  upon,  and  shall be fully
- --------------
protected in relying  upon,  any Notice of Revolving  Credit  Advance or similar
notice  believed  by Agent to be  genuine.  Agent may  assume  that each  Person
executing and delivering any notice in accordance  herewith was duly authorized,
unless the responsible  individual acting thereon for Agent has actual knowledge
to the contrary.  Each Borrower hereby designates Holdings as its representative
and agent on its behalf for the purposes of issuing Notices of Revolving  Credit
Advances,  giving  instructions with respect to the disbursement of the proceeds
of the  Loans,  requesting  Letters of Credit,  giving and  receiving  all other
notices and  consents  hereunder  or under any of the other Loan  Documents  and
taking all other actions  (including in respect of compliance with covenants) on
behalf of any Borrower or


              
<PAGE>



Borrowers under the Loan Documents.  Borrower Representative hereby accepts such
appointment.  Agent and each Lender may regard any notice or other communication
pursuant  to any Loan  Document  from  Borrower  Representative  as a notice  or
communication  from all  Borrowers,  and may give any  notice  or  communication
required  or  permitted  to be  given  to any  Borrower  or any  Borrower  Group
hereunder  to  Borrower  Representative  on behalf of such  Borrower or Borrower
Group.  Each  Borrower  agrees that each notice,  representation  and  warranty,
covenant,   agreement   and   undertaking   made  on  its  behalf  by   Borrower
Representative  shall be  deemed  for all  purposes  to have  been  made by such
Borrower and shall be binding upon and enforceable  against such Borrower to the
same extent as if the same had been made directly by such Borrower.

         1.2 Letters of Credit.  Subject to and in accordance with the terms and
             -----------------
conditions contained herein and in Annex B, Borrower  Representative,  on behalf
of the  applicable  Borrower,  shall have the right to  request,  and  Revolving
Lenders  agree to  incur,  or  purchase  participations  in,  Letter  of  Credit
Obligations  in respect of each  Borrower.  Each Letter of Credit  Obligation in
respect of AEC Funding  shall be in  Canadian  Dollars and each Letter of Credit
Obligation in respect of the Domestic Borrowers shall be in US Dollars.

         1.3      Prepayments
                  -----------

                  (a) Mandatory Prepayments.  (i) If at any time the outstanding
                      ---------------------
balance of the  aggregate  Revolving  Loan  (calculated  as a US Dollar  Amount)
exceeds the lesser of (A) the  Maximum  Amount and (B) the  Aggregate  Borrowing
Base,  Borrowers shall  immediately  repay the aggregate  outstanding  Revolving
Credit  Advances to the extent  required to eliminate  such excess.  If any such
excess remains after  repayment in full of the aggregate  outstanding  Revolving
Credit  Advances,  Borrowers  shall  provide cash  collateral  for the Letter of
Credit  Obligations in the manner set forth in Annex B to the extent required to
eliminate such excess. Furthermore,  if, at any time, the outstanding balance of
the Revolving Loan of any Borrower or Borrower Group exceeds that  Borrower's or
Borrower Group's separate Borrowing Base at any time the applicable  Borrower or
Borrower  Group shall  immediately  repay its Revolving  Credit  Advances in the
amount of such excess (and, if necessary,  shall provide cash collateral for its
Letter of Credit  Obligations  as  described  above).  For the  purposes of this
Section 1.3(a),  the Revolving Loan to AEC Funding and the Borrowing Base of AEC
Funding shall each be calculated in the US Dollar Amount thereof.

                           (ii)     Immediately upon receipt by any Credit Party
of proceeds of any Collateral,  such Credit  Party shall cause  Borrowers to 
prepay the Loans in an amount equal to all such proceeds,  net of (A) 
commissions and other  reasonable and customary transaction costs, fees and
expenses properly attributable to such transaction  and payable by such Credit 
Party in  connection  therewith (in each case,  paid to  non-Affiliates),  (B)
transfer  taxes,  (C) amounts  payable to holders  of  senior  Liens  (to  the
extent  such  Liens  constitute  Permitted Encumbrances hereunder), if any, and
(D) an appropriate reserve for income taxes in accordance with GAAP in 
connection  therewith.  Any such prepayment  shall be applied in accordance
with clause (b) below.




<PAGE>



                  (b)  Application  of  Certain   Mandatory   Prepayments.   Any
                       --------------------------------------------------
prepayments  made by any  Borrower  pursuant  to clause  (a)(ii)  above shall be
applied as follows:  first, to Fees and reimbursable  expenses of Agent then due
and payable pursuant to any of the Loan Documents;  second, to interest then due
and  payable  on  Revolving  Credit  Advances  made  to  such  Borrower  or such
Borrower's  Borrower Group;  third, to the principal balance of Revolving Credit
Advances  outstanding to such Borrower or such  Borrower's  Borrower Group until
the same  shall  have  been  paid in  full;  fourth,  to any  Letter  of  Credit
Obligations of such Borrower or such  Borrower's  Borrower Group to provide cash
collateral therefor in the manner set forth in Annex B, until all such Letter of
Credit  Obligations have been fully cash  collateralized in the manner set forth
in Annex B; fifth,  to interest  then due and  payable on the  Revolving  Credit
Advances  outstanding to each other Borrower or Borrower Group, pro rata; sixth,
to the  principal  balance of the Revolving  Credit  Advances made to each other
Borrower or  Borrower  Group,  pro rata,  until the same shall have been paid in
full,  and last to any Letter of Credit  Obligations  of each other  Borrower or
Borrower Group, pro rata, to provide cash collateral  therefor in the manner set
forth in Annex B, until all such  Letter of Credit  Obligations  have been fully
cash  collateralized.  The Revolving  Loan  Commitment  shall not be permanently
reduced by the amount of any such prepayments.

                  (c)  Application  of  Prepayments  from  Insurance   Proceeds.
                       --------------------------------------------------------
Prepayments  from insurance  proceeds in accordance with Section 5.4(c) shall be
applied as follows:  insurance proceeds from casualties or losses to cash or the
Collateral  shall be applied to the Revolving Credit Advances of the Borrower or
such  Borrower's  Borrower  Group that incurred such  casualties or losses.  The
Revolving Loan Commitment shall not be permanently  reduced by the amount of any
such prepayments. If the insurance proceeds received as to a particular Borrower
exceed the outstanding  principal balances of the Loans to that Borrower or such
Borrower's  Borrower  Group  or if the  precise  amount  of  insurance  proceeds
allocable to the  Collateral  are not otherwise  determined,  the allocation and
application  of those  proceeds  shall be  determined  by Agent,  subject to the
approval of Requisite Lenders.

                  (d)  Nothing  in  this  Section  1.3  shall  be  construed  to
constitute  Agent's or any Lender's  consent to any  transaction  referred to in
clause  (a)(ii)  above  which  is not  permitted  by  other  provisions  of this
Agreement or the other Loan Documents.

         1.4 Use of Proceeds. Each Borrower, individually, or, if applicable, as
             ---------------
a member of a Borrower  Group,  shall utilize the proceeds of the Revolving Loan
solely for the financing of its respective  ordinary  working  capital,  general
corporate needs (but excluding in any event the making of any Restricted Payment
not  specifically  permitted  by Section  6.14) and for such other  purposes  as
expressly permitted hereunder.  Disclosure Schedule (1.4) contains a description
of each Borrower's or Borrower Group's  respective  sources and uses of funds as
of the Closing Date, including Loans and Letter of Credit Obligations to be made
or incurred on that date, and a funds flow  memorandum  detailing how funds from
each source are to be transferred to particular uses.

         1.5 Interest and Applicable  Margins.  (a)(i) Domestic  Borrowers shall
             --------------------------------
pay interest to Agent, for the ratable benefit of Lenders in accordance with the
various Loans being made by each Lender, in arrears on each applicable  Interest
Payment Date, at the Index Rate plus the



<PAGE>



Applicable  Revolver  Index  Margin per annum based on the  aggregate  Revolving
Credit  Advances  outstanding to Domestic  Borrowers from time to time; and (ii)
AEC Funding shall pay interest to Agent,  for the ratable  benefit of Lenders in
accordance with the various Loans being made by each Lender,  in arrears on each
applicable  Interest Payment Date, at the applicable BA Rate plus the Applicable
BA Rate  Margin  per annum  based on the  aggregate  Revolving  Credit  Advances
outstanding to AEC Funding from time to time.

                  The  Applicable  Revolver  Index  Margin,  Applicable  BA Rate
Margin,  Applicable  L/C Margin and  Applicable  Unused  Line Fee Margin will be
2.00%, 2.00%, 1.00%, and .25% per annum, respectively.

                  (b) If any  payment on any Loan  becomes  due and payable on a
day other than a Business Day, the maturity thereof will be extended to the next
succeeding  Business Day and,  with respect to payments of  principal,  interest
thereon shall be payable at the then applicable rate during such extension.

                  (c) All  computations  of Fees calculated on a per annum basis
and  interest  shall be made by Agent on the basis of a three  hundred and sixty
(360) day year,  in each case for the  actual  number of days  occurring  in the
period for which such  interest  and Fees are  payable.  The Index Rate shall be
determined each day based upon the Index Rate as in effect each day. The BA Rate
shall be determined as specified in the  definition of "BA Rate" as set forth in
Annex A. Each  determination  by Agent of an  interest  rate and Fees  hereunder
shall be conclusive, absent manifest error.

                  (d) (i) If an Event of  Default  shall  have  occurred  and be
continuing  under  Section  8.1(a),  (h) or (i) or (ii) if any  other  Event  of
Default shall have  occurred and be continuing  and at the election of Agent (or
upon the written request of Requisite  Lenders) confirmed by written notice from
Agent to Borrower  Representative,  then the interest  rates  applicable  to the
Loans and the Letter of Credit Fees shall be  increased  by two percent (2%) per
annum above the rates of interest or the rate of such Fees otherwise  applicable
hereunder ("Default Rate"), and all outstanding  Obligations shall bear interest
at the Default  Rate  applicable  to such  Obligations.  Interest  and Letter of
Credit Fees at the  Default  Rate shall  accrue  from the  initial  date of such
Default or Event of Default  until that  Default or Event of Default is cured or
waived and shall be payable upon demand.

                  (e) Notwithstanding anything to the contrary set forth in this
Section 1.5, if a court of competent  jurisdiction  determines  in a final order
that the rate of interest payable hereunder exceeds the highest rate of interest
permissible  under law (the "Maximum Lawful Rate"),  then so long as the Maximum
Lawful Rate would be so exceeded,  the rate of interest payable  hereunder shall
be equal to the Maximum  Lawful  Rate;  provided,  however,  that if at any time
thereafter  the rate of  interest  payable  hereunder  is less than the  Maximum
Lawful Rate,  Borrowers shall continue to pay interest  hereunder at the Maximum
Lawful Rate until such time as the total interest  received by Agent,  on behalf
of Lenders,  is equal to the total  interest  which would have been received had
the  interest  rate  payable  hereunder  been  (but  for the  operation  of this
paragraph)  the  interest  rate  payable  since the  Closing  Date as  otherwise
provided in this Agreement.  Thereafter, interest hereunder shall be paid at the
rate(s) of interest and in the



<PAGE>



manner provided in Sections 1.5(a) through (d) above,  unless and until the rate
of  interest  again  exceeds  the  Maximum  Lawful  Rate,  and at that time this
paragraph  shall again apply.  In no event shall the total interest  received by
any Lender  pursuant  to the terms  hereof  exceed the amount  which such Lender
could lawfully have received had the interest due hereunder been  calculated for
the full term hereof at the Maximum  Lawful Rate. If the Maximum  Lawful Rate is
calculated  pursuant to this  paragraph,  such interest shall be calculated at a
daily rate equal to the Maximum Lawful Rate divided by the number of days in the
year in which such  calculation is made. If,  notwithstanding  the provisions of
this Section 1.5(e), a court of competent  jurisdiction  shall finally determine
that a Lender has received  interest  hereunder in excess of the Maximum  Lawful
Rate,  Agent shall, to the extent  permitted by applicable  law,  promptly apply
such excess in the order  specified in Section 1.10 and thereafter  shall refund
any excess to Borrowers or as a court of competent  jurisdiction  may  otherwise
order.

         1.6  Eligible  Accounts.  Based  on  the  most  recent  Borrowing  Base
              ------------------
Certificate delivered by each Borrower or Borrower Group, as the case may be, to
Agent and on other information available to Agent, Agent shall in its reasonable
credit  judgment  determine  which  Accounts of each Borrower shall be "Eligible
Accounts" for purposes of this  Agreement,  except any such Account to which any
of the  exclusionary  criteria set forth below applies  shall not  constitute an
"Eligible Account." Agent shall have the right to establish, modify or eliminate
Reserves  against Eligible  Accounts from time to time in its reasonable  credit
judgment.  In addition,  Agent reserves the right,  at any time and from time to
time after the Closing Date,  to adjust any of the criteria set forth below,  to
establish  new  criteria  and to adjust  advance  rates with respect to Eligible
Accounts,  in  its  reasonable  credit  judgment,  subject  to the  approval  of
Requisite  Lenders  in the case of  adjustments  or new  criteria  or changes in
advance  rates which have the effect of making more credit  available.  Eligible
Accounts shall not include any Account of any Borrower:

                  (a)  which  does  not  arise  from  the  sale of  goods or the
performance of services by such Borrower in the ordinary course of its business;

Account represents a progress billing consisting of an invoice for goods sold or
used or  services  rendered  pursuant  to a  contract  under  which the  Account
Debtor's obligation to pay that invoice is subject to such Borrower's completion
of further  performance  under such contract or is subject to the equitable lien
of a surety bond issuer;

                  (c) in the event  that any  defense,  counterclaim,  setoff or
dispute is asserted as to such Account;

indebtedness  incurred in the amount of the Account for  merchandise  sold to or
services rendered and accepted by the applicable Account Debtor;

                  (e) with respect to which an invoice,  acceptable  to Agent in

instrumentality thereof unless Agent, in its sole discretion,  has agreed to the
contrary in writing and such Borrower,  if necessary or desirable,  has complied
with the  Federal  Assignment  of Claims Act of 1940,  or any  applicable  state
statute or municipal  ordinance of similar  purpose and effect,  with respect to
such  obligation;  and (ii)  with  respect  to  Canadian  Accounts,  that is the
obligation of an Account Debtor that is the Canadian Government (Her Majesty the

Account is  assignable  by way of security  and such  Borrower,  if necessary or
desirable,  has complied with the Financial  Administration Act (Canada) and any
amendments thereto, or any applicable  provincial statute or municipal ordinance

                  (j) to the extent such Borrower or any  Subsidiary  thereof is

offset;

                  (k) that arises with respect to goods which are delivered on a
bill-and-hold,  cash-on-delivery basis or placed on consignment, guaranteed sale

Canadian)  receivership,  insolvency relief or other law or laws for the relief
of debtors;

                  (m)  which is the  obligation  of an  Account  Debtor if fifty

Lenders, is not a first priority perfected Lien;

                  (o)      as to which any of the representations or warranties
in the Loan Documents is untrue;

                  (p)      to the extent such Account is evidenced by a 
judgment, Instrument or Chattel Paper;

                  (q) to the  extent  such  Account  exceeds  any  credit  limit
established by Agent, in its reasonable credit judgment;

                  (r) to the extent that such  Account,  together with all other
Accounts  owing by such  Account  Debtor and its  Affiliates  (other  than those
Accounts   specified  on  Disclosure   Schedule   1.6(r))  as  of  any  date  of
determination exceed ten percent (10%) of all Eligible Accounts and with respect
to those Accounts  specified on Disclosure  Schedule  1.6(r),  as of any date of
determination exceed twenty percent (20%) of all Eligible Accounts;

                  (s) which is payable in any currency  other than US Dollars or

                  (t) which is otherwise unacceptable to Agent in its reasonable
credit judgment.

For the  purpose of valuing AEC  Funding's  Borrowing  Base in US Dollars,  such
Borrower's Eligible Accounts  denominated in Canadian Dollars shall be converted
by Borrower  Representative  into the US Dollar Amount  thereof as determined on
the date of delivery of the relevant Borrowing Base Certificate unless Agent has
notified AEC Funding or  Borrowing  Representative  that,  in light of recent or
expected currency  fluctuations,  the conversion shall be made on a more current
basis.

         1.7 Cash Management Systems. On or prior to the Closing Date, Borrowers
             -----------------------
will establish and will maintain until the Termination Date, the cash management

         1.8 Fees. (a) Borrowers shall pay to GE Capital, individually, the Fees

                  (b) As  additional  compensation  for the  Revolving  Lenders,
Borrowers  shall pay to Agent,  for the  ratable  benefit  of such  Lenders,  in
arrears,  on the  first  Business  Day of each  month  prior  to the  Commitment
Termination Date and on the Commitment Termination Date the following:

                           (i)      a fee for Borrowers' non-use of available 
funds in an amount equal to the Applicable Unused Line Fee Margin per annum 
(calculated on the basis of a 360 day year for actual days elapsed)  multiplied
by the difference  between (x) the  Maximum  Amount and (y) the  average  for 
the  period of the daily  closing balances of the aggregate Revolving Loan 
outstanding during the period for which such Fee is due.  For the  purposes  of
this  Section  1.8(b)(i)(y),  the  daily closing  balances of the aggregate  
Revolving  Loan  outstanding  to AEC Funding shall be calculated by Agent in
the US Dollar Amount thereof; and 

                           (ii)     with respect to any calendar month in which
the average aggregate daily  principal  balance of the Revolving Loan  
consisting of Revolving  Credit Advances  is less  than  $5,000,000,  Borrowers
shall  pay to  Lender a minimum borrowing  fee equal to the amount,  if any, by
which (A) the amount of interest charges  which would have been  payable for 
such month had the actual  aggregate daily  principal  balance of the Revolving
Loan  consisting of Revolving  Credit Advances for each day during such month 
been $5,000,000,  exceeds (B) the actual interest  charges payable upon the 
Revolving Loan consisting of Revolving Credit Advances for such month.  The 
minimum  borrowing fee shall be due and payable on the close of business on the
last day of each month in which a minimum borrowing fee is due and  payable.  
For the purposes of this  Section  1.8(b)(ii),  the US Dollar  Amount of the 
average  daily  principal  balance of the  Revolving  Loan consisting  of 
Revolving  Credit  Advances to AEC Funding  shall be added to the average daily
principal  balance of the Revolving Loan  consisting of Revolving Credit  
Advances to the Domestic  Borrowers  and the interest  charges  shall be 
determined as if such aggregate  Revolving Loan  consisting of Revolving  Credit
Advances is an Index Rate Loan.

                  (c) If Borrowers  prepay the Revolving  Loan and terminate the
Revolving Loan  Commitment,  whether  voluntarily or  involuntarily  and whether
before or after  acceleration of the Obligations,  Borrowers shall pay to Agent,
for the benefit of Lenders as liquidated  damages and compensation for the costs
of being  prepared  to make funds  available  hereunder  an amount  equal to the
Applicable  Percentage (as defined below) multiplied by the sum of the amount of
the Revolving Loan Commitment.  As used herein, the term "Applicable Percentage"
shall mean (x) two percent  (2%), in the case of a prepayment on or prior to the
first  anniversary  of the Closing Date,  (y) one percent (1%), in the case of a
prepayment  after the first  anniversary  of the Closing Date but on or prior to
the second  anniversary,  and (z) one percent  (1%), in the case of a prepayment
after the second anniversary. Notwithstanding anything to the contrary contained
in this Section  1.8(c),  in the event of the  termination  of this Agreement by
Borrowers  prior to the  Commitment  Termination  Date  and the  full and  final
repayment of all of the Obligations and the receipt by Agent and Lenders of cash
collateral all as provided  herein,  Borrowers  shall not be required to pay the
prepayment  fee  provided  for  above  if each of the  following  conditions  is
satisfied:  (i) no Default or Event of Default  shall exist or have occurred and
be  continuing,  (ii) Agent shall have  received  not less than thirty (30) days
prior  written  notice  of the  intention  of  Borrowers  to so  terminate  this
Agreement,  and (iii) the final  payment  in full of all of the  Obligations  is
received simultaneously with the sale of all or substantially all of the Capital
Stock



<PAGE>



or assets of Holdings  to ITEQ  Corporation  or the merger of Holdings  with and
into ITEQ Corporation and, in connection therewith,  GE Capital, in its sole and
absolute discretion,  elects to provide financing to ITEQ Corporation (either as
a lender or  co-lender)  with the proceeds of such  financing  used to repay the
Borrowers' Obligations hereunder.

         (d)  Borrowers  shall  pay to Agent,  for the  ratable  benefit  of the
Revolving Lenders, the Letter of Credit Fee as provided in Annex B.

         1.9 Receipt of  Payments.  Domestic  Borrowers  shall make each payment
             --------------------
under this  Agreement  not later than 2:00 p.m.  (New York time) on the day when
due in immediately  available  funds in US Dollars to the US Collection  Account
and AEC Funding shall make each payment under this Agreement not later than 2:00
p.m.  (New  York  time) on the day when due in  immediately  available  funds in
Canadian Dollars to the Canadian Collection  Account.  For purposes of computing
interest  and Fees  and  determining  Borrowing  Availability  or Net  Borrowing
Availability as of any date, all payments shall be deemed received on the day of
receipt of immediately  available  funds  therefor in the respective  Collection
Account prior to 2:00 p.m. New York time.  Payments received after 2:00 p.m. New
York time on any  Business  Day shall be  deemed  to have been  received  on the
following  Business  Day.  Notwithstanding  anything to the  contrary  contained
herein, if Agent receives any payment from or on behalf of any Credit Party in a
currency  other than the  currency  in which an  Obligation  due and  payable is
denominated,  Agent may convert the payment  (including the monetary proceeds of
realization  upon any  Collateral  and any funds then held in a cash  collateral
account) into the currency of the relevant  Obligation at the exchange rate that
Agent would be prepared to sell the currency in which the relevant Obligation is
denominated  against  the  currency  received  in New York on the  Business  Day
immediately  preceding  the date of actual  payment.  The  Obligations  shall be
satisfied only to the extent of the amount actually  received by Agent upon such
conversion.

         1.10 Application and Allocation of Payments.  (a) So long as no Default
              --------------------------------------
or Event of Default has occurred and is continuing,  (i) payments  consisting of
proceeds  of  Accounts  received in the  ordinary  course of  business  shall be
applied  to the  Revolving  Loan;  (ii)  payments  matching  specific  scheduled
payments  then due  shall be  applied  to those  scheduled  payments;  and (iii)
mandatory prepayments shall be applied as set forth in Section 1.3. All payments
and  prepayments  applied to a particular  Loan shall be applied  ratably to the
portion  thereof held by each Lender as determined by its Pro Rata Share.  As to
each  other  payment,  and as to all  payments  made when a Default  or Event of
Default has occurred and is continuing or following the  Commitment  Termination
Date,  each  Borrower  hereby   irrevocably  waives  the  right  to  direct  the
application of any and all payments received from or on behalf of such Borrower,
and each Borrower hereby irrevocably agrees that Agent shall have the continuing
exclusive  right to apply any and all such payments  against the  Obligations of
Borrowers as Agent may deem  advisable  notwithstanding  any  previous  entry by
Agent in the Loan  Account or any other books and  records.  In the absence of a
specific determination by Agent with respect thereto,  payments shall be applied
to amounts then due and payable in the following  order: (1) to Fees and Agent's
expenses reimbursable hereunder;  (2) to interest on the other Loans, ratably in
proportion to the interest accrued as to each Loan; (3) to principal payments on
the other Loans and to provide cash collateral for Letter of Credit  Obligations
in the manner described in Annex B, ratably to the aggregate, combined principal
balance of the other Loans and outstanding Letter of Credit



<PAGE>



Obligations;  and (4) to all other Obligations  including expenses of Lenders to
the extent reimbursable under Section 11.3.

                  (b) Agent is  authorized  to,  and at its sole  election  may,
charge to the Revolving  Loan balance on behalf of each Borrower and cause to be
paid all  Fees,  expenses,  Charges,  costs  (including  insurance  premiums  in
accordance  with Section  5.4(a)) and interest and principal  owing by Borrowers
under this  Agreement  or any of the other Loan  Documents  if and to the extent
Borrowers  fail to promptly pay any such  amounts as and when due,  even if such
charges  would  cause the  balance  of the  aggregate  Revolving  Loan to exceed
Borrowing  Availability  or would cause the balance of the Revolving Loan of any
Borrower to exceed such  Borrower's  separate  Borrowing Base. At Agent's option
and to the extent permitted by law, any charges so made shall constitute part of
the Revolving Loan hereunder.

         1.11 Loan Account and  Accounting.  Agent shall maintain a loan account
              ----------------------------
(the "Loan Account") on its books to record: all Advances,  all payments made by
Borrowers,  and all other debits and credits as provided in this  Agreement with
respect to the Loans or any other  Obligations.  All entries in the Loan Account
shall be made in accordance with Agent's  customary  accounting  practices as in
effect  from time to time.  The  balance in the Loan  Account,  as  recorded  on
Agent's most recent printout or other written statement,  shall, absent manifest
error, be presumptive evidence of the amounts due and owing to Agent and Lenders
by each  Borrower;  provided  that any  failure  to so record or any error in so
recording  shall not limit or otherwise  affect any  Borrower's  duty to pay the
Obligations.  Agent shall render to Borrower Representative a monthly accounting
of transactions  with respect to the Loans setting forth the balance of the Loan
Account as to each Borrower.  Unless Borrower  Representative  notifies Agent in
writing of any objection to any such  accounting  (specifically  describing  the
basis for such objection),  within thirty (30) days after the date thereof, each
and every such accounting shall (absent manifest error) be deemed final, binding
and  conclusive  upon  Borrowers  in all  respects as to all  matters  reflected
therein.  Only those items expressly  objected to in such notice shall be deemed
to be disputed by Borrowers.  Notwithstanding  any provision herein contained to
the contrary,  any Lender may elect (which  election may be revoked) to dispense
with the  issuance of Notes to that  Lender and may rely on the Loan  Account as
evidence of the amount of Obligations from time to time owing to it.

         1.12  Indemnity.  Each Credit  Party that is a signatory  hereto  shall
               ---------
jointly and severally  indemnify  and hold  harmless each of Agent,  Lenders and
their  respective  Affiliates,  and  each  such  Person's  respective  officers,
directors,   employees,   attorneys,   agents  and  representatives   (each,  an
"Indemnified Person"), from and against any and all suits, actions, proceedings,
claims,  damages,   losses,   liabilities  and  expenses  (including  reasonable
attorneys' fees and  disbursements  and other costs of investigation or defense,
including  those  incurred  upon any appeal) which may be instituted or asserted
against  or  incurred  by any such  Indemnified  Person as the  result of credit
having been extended, suspended or terminated under this Agreement and the other
Loan Documents and the  administration of such credit, and in connection with or
arising out of the  transactions  contemplated  hereunder and thereunder and any
actions  or  failures  to act in  connection  therewith,  including  any and all
Environmental  Liabilities  and  legal  costs  and  expenses  arising  out of or
incurred in connection with disputes  between or among any parties to any of the
Loan Documents (collectively, "Indemnified Liabilities"); provided, that no such
Credit Party


<PAGE>


shall be liable for any indemnification to an Indemnified Person to the extent
that any such suit, action, proceeding, claim, damage, loss, liability or 
expense results from that Indemnified Person's gross negligence or willful
misconduct.  NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE  OR LIABLE TO ANY OTHER
PARTY TO ANY LOAN  DOCUMENT,  ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY
BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS  DERIVATIVELY  
THROUGH SUCH PARTY, FOR INDIRECT,  PUNITIVE,  EXEMPLARY OR CONSEQUENTIAL  
DAMAGES  WHICH MAY BE ALLEGED AS A RESULT OF CREDIT  HAVING  BEEN EXTENDED,  
SUSPENDED OR TERMINATED UNDER ANY LOAN DOCUMENT OR AS A RESULT OF ANY OTHER 
TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

         1.13 Access.  Each Credit Party which is a party hereto  shall,  during
              ------
normal  business  hours,  from time to time upon two (2)  Business  Days'  prior
notice as frequently as Agent  determines to be  appropriate:  (a) provide Agent
and  any of  its  officers,  employees  and  agents  access  to its  properties,
facilities, advisors and employees (including officers) of each Credit Party and
to the  Collateral,  (b) permit Agent,  and any of its  officers,  employees and
agents,  to inspect,  audit and make extracts from any Credit  Party's books and
records,  and (c) permit  Agent,  and its  officers,  employees  and agents,  to
inspect,  review,  evaluate  and  make  test  verifications  and  counts  of the
Accounts,  Inventory and other  Collateral of any Credit Party.  If a Default or
Event of Default has  occurred  and is  continuing  or if access is necessary to
preserve or protect the  Collateral  as  determined  by Agent,  each such Credit
Party  shall  provide  such  access to Agent and to each Lender at all times and
without  advance  notice.  Furthermore,  so long as any  Event  of  Default  has
occurred and is continuing,  Borrowers  shall provide Agent and each Lender with
access to their suppliers and customers.  Each Credit Party shall make available
to Agent and its  counsel,  as quickly as is possible  under the  circumstances,
originals  or copies of all books and  records  which  Agent may  request.  Each
Credit Party shall deliver any document or instrument necessary for Agent, as it
may from time to time  request,  to obtain  records  from any service  bureau or
other Person which maintains  records for such Credit Party,  and shall maintain
duplicate records or supporting documentation on media, including computer tapes
and discs owned by such Credit Party.  Agent will give Lenders at least ten (10)
days' prior written notice of regularly  scheduled  audits.  Representatives  of
other  Lenders may  accompany  Agent's  representatives  on regularly  scheduled
audits at no charge to Borrowers.

         1.14  Taxes.  (a) Any  and all  payments  by  each  Borrower  hereunder
               -----
(including any payments made pursuant to Section 12) or under the Notes shall be
made,  in  accordance  with this  Section  1.14,  free and clear of and  without
deduction  for any and all present or future  Taxes.  If any  Borrower  shall be
required  by law to  deduct  any Taxes  from or in  respect  of any sum  payable
hereunder (including any sum payable pursuant to Section 12) or under the Notes,
(i) the sum payable  shall be  increased  as much as shall be  necessary so that
after  making  all  required  deductions  (including  deductions  applicable  to
additional  sums  payable  under  this  Section  1.14)  Agent  or  Lenders,   as
applicable,  receive an amount equal to the sum they would have  received had no
such deductions been made,  (ii) such Borrower shall make such  deductions,  and
(iii) such Borrower shall pay the full amount deducted to the relevant taxing or
other authority in accordance with applicable law. Within thirty (30) days after
the date of any payment of Taxes, Borrower Representative shall furnish to Agent
the original or a certified copy of a receipt evidencing payment thereof.


<PAGE>


                  (b) Each Credit Party that is a signatory hereto shall jointly
and severally indemnify and, within ten (10) days of demand therefor,  pay Agent
and each Lender for the full amount of Taxes (including any Taxes imposed by any
jurisdiction  on amounts  payable under this Section 1.14) paid by Agent or such
Lender, as appropriate,  and any liability  (including  penalties,  interest and
expenses) arising  therefrom or with respect thereto,  whether or not such Taxes
were correctly or legally asserted.

                  (c) Each  Lender  organized  under the laws of a  jurisdiction
outside the United States (a "Foreign  Lender") as to which  payments to be made
under  this  Agreement  or  under  the  Notes  are  exempt  from  United  States
withholding  tax under an  applicable  statute  or tax treaty  shall  provide to
Borrower  Representative  and Agent a properly  completed  and executed IRS Form
4224 or Form 1001 or other applicable form,  certificate or document  prescribed
by the  IRS  or  the  United  States  certifying  as to  such  Foreign  Lender's
entitlement to such exemption (a "Certificate of Exemption"). Any foreign Person
that seeks to become a Lender under this  Agreement  shall provide a Certificate
of  Exemption  to Borrower  Representative  and Agent prior to becoming a Lender
hereunder.  No foreign  Person may become a Lender  hereunder  if such Person is
unable to deliver a Certificate of Exemption.

         1.15 Capital Adequacy;  Increased Costs; Illegality.  (a) If any Lender
              ----------------------------------------------
shall have determined that any law, treaty, governmental (or quasi-governmental)
rule,  regulation,  guideline  or  order  regarding  capital  adequacy,  reserve
requirements  or similar  requirements  or  compliance  by any  Lender  with any
request or directive regarding capital adequacy, reserve requirements or similar
requirements  (whether  or not having the force of law),  in each case,  adopted
after the Closing Date,  from any central bank or other  Governmental  Authority
increases or would have the effect of increasing the amount of capital, reserves
or other funds required to be maintained by such Lender and thereby reducing the
rate of return on such  Lender's  capital as a  consequence  of its  obligations
hereunder,  then  Borrowers  shall from time to time upon  demand by such Lender
(with a copy of such  demand to Agent)  pay to Agent,  for the  account  of such
Lender,  additional  amounts  sufficient  to  compensate  such  Lender  for such
reduction.  A  certificate  as to the amount of that  reduction  and showing the
basis  of  the  computation   thereof  submitted  by  such  Lender  to  Borrower
Representative and to Agent shall,  absent manifest error, be final,  conclusive
and binding for all purposes.

                  (b) If, due to either (i) the introduction of or any change in
any law or regulation (or any change in the interpretation  thereof) or (ii) the
compliance  with  any  guideline  or  request  from  any  central  bank or other
Governmental  Authority  (whether or not having the force of law),  in each case
adopted after the Closing  Date,  there shall be any increase in the cost to any
Lender of  agreeing to make or making,  funding or  maintaining  any Loan,  then
Borrowers  shall from time to time,  upon demand by such Lender  (with a copy of
such demand to Agent),  pay to Agent for the  account of such Lender  additional
amounts  sufficient  to  compensate  such  Lender  for such  increased  cost.  A
certificate  as to the amount of such  increased  cost,  submitted  to  Borrower
Representative  and to Agent by such Lender,  shall be conclusive and binding on
Borrowers for all purposes,  absent manifest error.  Each Lender agrees that, as
promptly as practicable after it becomes aware of any circumstances  referred to
above which would result in any such increased  cost, the affected Lender shall,

Lender's internal  policies of general  application,  use reasonable  commercial
efforts to  minimize  costs and  expenses  incurred  by it and  payable to it by
Borrowers pursuant to this Section 1.15(b).

                  (c)  Replacement  of Lender in  Respect  of  Increased  Costs.
                       --------------------------------------------------------
Within  fifteen (15) days after  receipt by Borrower  Representative  of written
notice  and  demand  from any  Lender  (an  "Affected  Lender")  for  payment of
additional amounts or increased costs as provided in Section 1.14(a), 1.15(a) or
1.15(b),  Borrower  Representative  may,  at its option,  notify  Agent and such
Affected Lender of its intention to replace the Affected  Lender.  So long as no
Default  or  Event  of  Default  has  occurred  and  is   continuing,   Borrower
Representative,  with the consent of Agent, may obtain, at Borrowers' expense, a
replacement  Lender  ("Replacement  Lender")  for  the  Affected  Lender,  which
Replacement  Lender  must be  satisfactory  to  Agent.  If  Borrowers  obtain  a
Replacement  Lender within ninety (90) days following  notice of their intention
to do so, the Affected  Lender must sell and assign its Loans and Commitments to
such  Replacement  Lender for an amount  equal to the  principal  balance of all
Loans held by the Affected Lender and all accrued interest and Fees with respect
thereto  through  the date of such  sale,  provided  that  Borrowers  shall have
reimbursed  such Affected  Lender for the additional  amounts or increased costs
that it is entitled  to receive  under this  Agreement  through the date of such
sale and assignment.

Notwithstanding  the foregoing,  Borrowers  shall not have the right to obtain a
Replacement  Lender if the Affected  Lender  rescinds  its demand for  increased
costs or additional  amounts  within  fifteen (15) days following its receipt of
Borrowers' notice of intention to replace such Affected Lender.  Furthermore, if
Borrowers  give a notice of  intention  to replace  and do not so  replace  such
Affected Lender within ninety (90) days thereafter, Borrowers' rights under this
Section 1.15(c) shall terminate unless increased costs or additional amounts are
subsequently  claimed by such Affected  Lender and Borrowers  shall promptly pay
all increased  costs or  additional  amounts  demanded by such  Affected  Lender
pursuant to Sections 1.14(a), 1.15(a) and 1.15(b).

         1.16  Single  Loan.  All  Loans to each  Borrower  and all of the other
               ------------
Obligations  of each Borrower  arising  under this  Agreement and the other Loan
Documents  shall  constitute  one general  obligation of that Borrower  secured,
until the Termination Date, by all of the Collateral.

         1.17 Currency Matters. Principal, interest,  reimbursement obligations,
              ----------------
fees,  and all other  amounts  payable  under this  Agreement and the other Loan
Documents  to Agent and Lenders  shall be payable in the  currency in which such
Obligations  are  denominated.   Unless  stated  otherwise,   all  calculations,
comparisons,  measurements or determinations  under this Agreement shall be made
in US Dollars. For the purpose of such calculations,  comparisons,  measurements
or determinations, amounts denominated in other currencies shall be converted by
Agent  in the  Equivalent  Amount  of US  Dollars  on the  date of  calculation,
comparison, measurement or determination.

2.       CONDITIONS PRECEDENT

         2.1  Conditions to the Initial  Loans.  No Lender shall be obligated to
              --------------------------------
make any Loan or incur any Letter of Credit  Obligations on the Closing Date, or

other action  hereunder,  until the following  conditions have been satisfied or

and Lenders:

instruments,  agreements and legal opinions as Agent shall reasonably request in
connection  with the  transactions  contemplated by this Agreement and the other

hereto as Annex D, each in form and substance satisfactory to Agent.

                  (b)  Approvals.  Agent shall have  received  (i)  satisfactory

Documents or (ii) an officer's certificate in form and substance satisfactory to
Agent affirming that no such consents or approvals are required.

                       ---------------------
Borrower  supporting the initial Revolving Credit Advance and the initial Letter
of Credit Obligations  incurred and the amount of the Reserves to be established
on the Closing Date shall be  sufficient in value,  as  determined by Agent,  to
provide Borrowers,  collectively, with Net Borrowing Availability,  after giving
effect to the initial Revolving Credit Advance made hereunder and the incurrence
of any initial Letter of Credit  Obligations  (on a pro forma basis,  with trade
payables being paid currently,  and expenses and  liabilities  being paid in the
ordinary  course of  business  and  without  acceleration  of sales) of at least
$7,500,000.  For the purposes of this Section 2.1(c), any Loan to be made to AEC
Funding and the determination of the Net Borrowing  Availability for AEC Funding
shall be calculated in the US Dollar Amount thereof.

                  (d)  Payment  of  Fees.  Borrowers  shall  have  paid the Fees
                       -----------------
required to be paid on the Closing Date in the respective  amounts  specified in
Section 1.8  (including  the Fees  specified in the GE Capital Fee Letter),  and
shall  have  reimbursed  Agent  for all  fees,  costs and  expenses  of  closing

structure of each Credit Party and the terms and conditions of all  Indebtedness
of each Credit Party shall be acceptable to Agent in its sole discretion.

         2.2 Further  Conditions  to Each Loan.  Except as  otherwise  expressly
             ---------------------------------
provided  herein,  no Lender  shall be  obligated  to fund any Loan or incur any

***
                  (a)  Any  representation  or  warranty  by  any  Credit  Party
contained  herein  or in any of the  other  Loan  Documents  shall be  untrue or
incorrect  as of such date,  except to the extent  that such  representation  or
warranty  expressly  relates to an earlier  date and except for changes  therein
expressly permitted or expressly contemplated by this Agreement; or


<PAGE>


                  (b) Any event or circumstance having a Material Adverse Effect
shall  have  occurred  since the date  hereof  as  determined  by the  Requisite
Lenders; or

                  (c) Any  Default  or  Event of  Default  has  occurred  and is
continuing or would result after giving effect to any Advance (or the incurrence

determined not to make any Advance or incur any Letter of Credit Obligation as a
result of that Default or Event of Default, or

                  (d) After giving  effect to any Advance (or the  incurrence of
any Letter of Credit Obligations),  (i) the outstanding  principal amount of the
aggregate Revolving Loan would exceed the lesser of the Aggregate Borrowing Base
and the  Maximum  Amount,  or  (ii)  the  outstanding  principal  amount  of the
Revolving  Loan of the  applicable  Borrower or Borrower Group would exceed such
Borrower's or Borrower  Group's  respective  separate  Borrowing  Base.  For the
purposes of this Section 2.2(d), any Revolving Loan outstanding or to be made to
AEC Funding shall be calculated in the US Dollar Amount thereof.

The request and  acceptance by any Borrower or Borrower Group of the proceeds of
any Loan, or the incurrence of any Letter of Credit Obligation,  shall be deemed
to constitute, as of the date of such request,  acceptance or incurrence,  (i) a
representation and warranty by Borrowers that the conditions in this Section 2.2
have been satisfied and (ii) a reaffirmation by Borrowers of the  cross-guaranty
provisions  set forth in  Section  12 and of the  granting  and  continuance  of
Agent's  Liens,  on behalf of itself and  Lenders,  pursuant  to the  Collateral
Documents.

             -----------------------------------------
a corporation or limited  partnership  duly organized,  validly  existing and in
good standing under the laws of its jurisdiction of  incorporation;  (b) is duly
qualified to conduct business and is in good standing in each other jurisdiction

requisite  corporate or limited  partnership  power and  authority and the legal
right to own, pledge, mortgage or otherwise encumber and operate its properties,
to lease the  property  it operates  under lease and to conduct its  business as
now,  heretofore  and  proposed  to  be  conducted;   (d)  subject  to  specific
representations  regarding  Environmental  Laws,  has  all  licenses,   permits,

              ------------------------------------------------------------

Date,  each of the Loan Documents shall have been duly executed and delivered by
each Credit Party that is a party thereto and each such Loan Document shall then
constitute  a  legal,   valid  and  binding  obligation  of  such  Credit  Party
enforceable against it in accordance with its terms.

             -------------------------------------
all Financial  Statements  concerning  Holdings and its  Subsidiaries  which are
referenced below have been prepared in accordance with GAAP consistently applied
throughout the periods  covered  (except as disclosed  therein and except,  with
respect to unaudited  Financial  Statements,  for the absence of  footnotes  and
normal year-end audit  adjustments) and present fairly in all material  respects
the financial  position of the Persons  covered  thereby as at the dates thereof

Borrowers  in light of the past  operations  of  their  businesses  and  reflect
projections for the one (1) year period beginning on March 1, 1999 on a month by
month basis for the first year.  The  Projections  are based upon  estimates and
assumptions stated therein,  all of which Borrowers believe to be reasonable and

Date,  (a)  no  Credit  Party  has  incurred  any  obligations,   contingent  or
non-contingent liabilities, liabilities for Charges, long-term leases or unusual
forward  or  long-term  commitments  which,  alone  or in the  aggregate,  could
reasonably be expected to have a Material Adverse Effect, (b) no contract, lease
or other  agreement or  instrument  has been entered into by any Credit Party or

occurred,  which  alone or  together  with other  events,  could  reasonably  be
expected to have a Material Adverse Effect.

         3.6  Ownership of Property;  Liens.  As of the Closing  Date,  the real
              -----------------------------
estate ("Real  Estate") listed on Disclosure  Schedule (3.6)  constitutes all of
the real property owned,  leased,  subleased,  or used by any Credit Party. Each

Encumbrances,  and there are no facts,  circumstances or conditions known to any
Credit  Party  that may  result  in any Liens  (including  Liens  arising  under
Environmental  Laws) other than  Permitted  Encumbrances.  Each Credit Party has
received  all  deeds,  assignments,   waivers,  consents,   non-disturbance  and
attornment or similar  agreements,  bills of sale and other  documents,  and has
duly effected all recordings,  filings and other actions necessary to establish,
protect and perfect such Credit Party's right,  title and interest in and to all
such Real Estate and other properties and assets. Disclosure Schedule (3.6) also
describes any purchase options, rights of first refusal or


<PAGE>


other  similar  contractual  rights  pertaining  to any Real  Estate.  As of the
Closing  Date,  no portion of any Credit  Party's  Real Estate has  suffered any
material  damage by fire or other  casualty loss which has not  heretofore  been
repaired  and restored in all  material  respects to its  original  condition or
otherwise  remedied.  As of the Closing Date, all material  permits  required to
have  been  issued  or  appropriate  to enable  the Real  Estate to be  lawfully

Schedule  (3.7)  have been  delivered  to  Agent);  (e)  there is no  organizing
activity involving any Credit Party pending or, to any Credit Party's knowledge,
threatened  by  any  labor  union  or  group  of  employees;  (f)  there  are no
representation   proceedings  pending  or,  to  any  Credit  Party's  knowledge,
threatened with the National Labor Relations Board or any labor relations board,

pending  demand  for  recognition;  and (g)  except as set  forth in  Disclosure
Schedule  (3.7),  there are no  complaints  or charges  against any Credit Party
pending or, to the  knowledge of any Credit  Party,  threatened to be filed with
any Governmental Authority or arbitrator based on, arising out of, in connection
with, or otherwise  relating to the  employment or  termination of employment by
any Credit Party of any individual.

         3.8  Ventures,  Subsidiaries  and  Affiliates;  Outstanding  Stock  and
              ------------------------------------------------------------------

securities of its  Subsidiaries.  All  outstanding  Indebtedness  of each Credit
Party as of the Closing Date is described in Section 6.3  (including  Disclosure
Schedule (6.3)).

         3.9 Government  Regulation.  No Credit Party is an "investment company"
             ----------------------
or an "affiliated  person" of, or "promoter" or "principal  underwriter" for, an
"investment company," as such terms are defined in the Investment Company Act of
1940. No Credit Party is subject to regulation  under the Public Utility Holding
Company Act of 1935,  the Federal  Power Act,  or any  Canadian or other  United
States  federal law or state,  provincial,  local or foreign law or statute that
restricts  or  limits  its  ability  to incur  Indebtedness  or to  perform  its
obligations  hereunder.  The making of the Loans by Lenders  to  Borrowers,  the
incurrence of the Letter of Credit Obligations


<PAGE>


on  behalf of  Borrowers  and,  the  application  of the  proceeds  thereof  and
repayment  thereof  will not violate any  provision  of any such  statute or any
rule, regulation or order issued by the Securities and Exchange Commission.

         3.10  Margin  Regulations.  No  Credit  Party is  engaged,  nor will it
               -------------------
engage,  principally or as one of its important  activities,  in the business of
extending  credit for the  purpose of  "purchasing"  or  "carrying"  any "margin
security" as such terms are defined in Regulation U of the Federal Reserve Board
as now and from time to time hereafter in effect (such securities being referred
to herein as "Margin Stock"). No Credit Party owns any Margin Stock, and none of
the proceeds of the Loans or other  extensions  of credit  under this  Agreement
will be used, directly or indirectly,  for the purpose of purchasing or carrying
any Margin Stock, 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 cause any of the Loans or other  extensions of credit under
this  Agreement  to be  considered  a "purpose  credit"  within  the  meaning of
Regulations T, U or X of the Federal Reserve Board. No Credit Party will take or
permit to be taken any action which might cause any Loan Document to violate any
regulation of the Federal Reserve Board.

         3.11  Taxes.  All  tax  returns,  reports  and  statements,   including
               -----
information returns,  required by any Governmental  Authority to be filed by any
Credit Party have been filed with the appropriate Governmental Authority and all
Charges have been paid prior to the date on which any fine, penalty, interest or
late  charge may be added  thereto  for  nonpayment  thereof  (or any such fine,
penalty,  interest,  late  charge or loss has been paid),  excluding  Charges or
other amounts  being  contested in accordance  with Section  5.2(b).  Proper and
accurate  amounts have been  withheld by each Credit  Party from its  respective
employees  for all  periods  in full and  complete  compliance  in all  material
respects with all applicable federal,  state, local,  provincial and foreign law
and such  withholdings  have been  timely  paid to the  respective  Governmental
Authorities.  Disclosure Schedule (3.11) sets forth as of the Closing Date those
taxable  years for which any Credit  Party's  tax returns  are  currently  being
audited by Revenue Canada,  the IRS or any other applicable  provincial or state
Governmental   Authority  and  any  assessments  or  threatened  assessments  in
connection  with such  audit,  or  otherwise  currently  outstanding.  Except as
described on Disclosure  Schedule (3.11),  no Credit Party has executed or filed
with  Revenue  Canada,  the IRS or any other  provincial  or state  Governmental
Authority any  agreement or other  document  extending,  or having the effect of
extending,  the period for assessment or collection of any Charges.  None of the
Credit Parties and their respective predecessors are liable for any Charges: (a)
under any agreement (including any tax sharing agreements) or (b) to each Credit
Party's knowledge, as a transferee.  As of the Closing Date, no Credit Party has
agreed or been requested to make any  adjustment  under IRC Section  481(a),  by
reason of a change  in  accounting  method  or  otherwise,  which  would  have a
Material Adverse Effect.

         3.12  ERISA.  (a)  Disclosure  Schedule  (3.12)  lists  all  Plans  and
               -----
separately identifies all Pension Plans, including Title IV Plans, Multiemployer
Plans, ESOPs and Welfare Plans,  including all Retiree Welfare Plans.  Copies of
all such  listed  Plans,  together  with a copy of the latest form 5500 for each
such Plan,  have been delivered to Agent.  Except with respect to  Multiemployer
Plans,  each  Qualified  Plan has been  determined  by the IRS to qualify  under
Section 401 of the IRC, and the trusts created  thereunder  have been determined
to be exempt


<PAGE>


from tax under  the  provisions  of  Section  501 of the IRC,  and  nothing  has
occurred which would cause the loss of such  qualification or tax-exempt status.
Each  Plan is in  compliance,  in all  material  respects,  with the  applicable
provisions  of  ERISA  and the IRC,  including  the  timely  filing  of  IRS/DOL
5500-series  form reports  required  under the IRC or ERISA.  No Credit Party or
ERISA  Affiliate has failed to make any  contribution or pay any material amount
due as required by either  Section 412 of the IRC or Section 302 of ERISA or the
terms of any such Plan.  No Credit  Party or ERISA  Affiliate  has  engaged in a
"prohibited  transaction,"  as defined in Section 4975 of the IRC, in connection
with any Plan,  which  would  subject  any  Credit  Party to a  material  tax on
prohibited transactions imposed by Section 4975 of the IRC.

                  (b) Disclosure Schedule (3.12) sets forth all Canadian Benefit
                      --------------------------
Plans (other than,  for greater  certainty,  universal  plans  created by and to
which any Credit  Party is  obligated  to  contribute  by statute)  and Canadian
Pension Plans adopted by each Credit Party.  The Canadian Pension Plans are duly
registered   under  the  ITA  and  all  other   applicable  laws  which  require
registration  and no event has occurred which is reasonably  likely to cause the
loss of such registered  status.  All material  obligations of each Credit Party
(including  fiduciary,   funding,  investment  and  administration  obligations)
required to be performed in connection  with the Canadian  Pension Plans and the

insurance  described  on  Disclosure  Schedule  (3.18)  as in effect on the date
hereof or  otherwise  in form and amounts  customary  for their  businesses  and
industry and acceptable to Agent and with insurers  acceptable to Agent.  If any
Credit Party at any time or times hereafter shall fail to obtain or maintain any
of the policies of  insurance  required  above or to pay all  premiums  relating
thereto,  Agent may at any time or times  thereafter  obtain and  maintain  such
policies  of  insurance  and pay such  premiums  and take any other  action with

maintained by any Credit Party or any laws affecting the potential  liability of
such Credit  Party) to require  additional  forms and limits of insurance to, in
Agent's opinion,  adequately  protect both Agent's and Lenders' interests in all
or any  portion  of the  Collateral  and to  ensure  that each  Credit  Party is
protected by insurance in amounts and with coverage  customary for its industry.
If  requested by Agent,  each Credit  Party shall  deliver to Agent from time to
time a report of a  reputable  insurance  broker,  satisfactory  to Agent,  with
respect to its insurance policies.


<PAGE>


                  (c) Each  Credit  Party  shall  deliver to Agent,  in form and
substance satisfactory to Agent, endorsements to (i) all "All Risk" and business
interruption  insurance  naming Agent, on behalf of itself and Lenders,  and (if
applicable,  with respect to any insurance policy covering assets located in the
Province  of  Quebec)  Agent and  Lenders,  as loss  payee,  and,  to the extent
applicable,  containing the standard  mortgage  clause approved by the Insurance
Bureau of Canada, (ii) all general liability and other liability policies naming
Agent,  on behalf of itself and  Lenders,  and (with  respect  to any  insurance
policy covering assets located in the Province of Quebec) Agent and Lenders,  as
additional  insured.  Each  Credit  Party  irrevocably  makes,  constitutes  and
appoints Agent (and all officers,  employees or agents  designated by Agent), so
long as any Default or Event of Default has  occurred and is  continuing  or the
anticipated  insurance proceeds exceed $250,000, as such Credit Party's true and
lawful  agent and  attorney-in-fact  for the  purpose  of making,  settling  and
adjusting claims under such "All Risk" policies of insurance, endorsing the name
of such Credit  Party on any check or other item of payment for the  proceeds of
such "All Risk"  policies of  insurance  and for making all  determinations  and
decisions  with respect to such "All Risk"  policies of  insurance.  Agent shall
have no duty to  exercise  any rights or powers  granted to it  pursuant  to the
foregoing power-of-attorney. Borrower Representative shall promptly notify Agent
of any loss,  damage, or destruction to the Collateral in the amount of $250,000
or more, whether or not covered by insurance. After deducting from such proceeds
the expenses,  if any,  incurred by Agent in the collection or handling thereof,
Agent  may,  at  its  option,  apply  such  proceeds  to  the  reduction  of the
Obligations  in  accordance  with Section  1.3(c);  provided that in the case of
insurance proceeds  pertaining to any Credit Party that is not a Borrower,  such
insurance  proceeds  shall be applied  ratably to all of the Loans owing by each
Borrower, or permit or require the applicable Credit Party to use such money, or
any part thereof,  to replace,  repair,  restore or rebuild the  Collateral in a
diligent and expeditious  manner with materials and workmanship of substantially
the  same  quality  as  existed   before  the  loss,   damage  or   destruction.
Notwithstanding  the  foregoing,  if the casualty  giving rise to such insurance
proceeds would not reasonably be expected to have a Material  Adverse Effect and
such insurance  proceeds do not exceed  $250,000 in the  aggregate,  Agent shall
permit the applicable  Credit Party to replace,  restore,  repair or rebuild the
property; provided that if such Credit Party shall not have completed or entered
into binding  agreements to complete such  replacement,  restoration,  repair or
rebuilding  within 180 days of such  casualty,  Agent may apply  such  insurance
proceeds to the Obligations in accordance with Section 1.3(c);  provided further
that in the case of insurance  proceeds  pertaining  to any Credit Party that is
not a Borrower,  such insurance  proceeds shall be applied ratably to all of the
Loans  owing by each  Borrower  or  Borrower  Group,  as the  case  may be.  All
insurance  proceeds  which are to be made  available to any Borrower to replace,
repair,  restore or rebuild the  Collateral  shall be applied by Agent to reduce
the outstanding  principal balance of the Revolving Loan of such Borrower (which
application  shall not result in a permanent  reduction  of the  Revolving  Loan
Commitment) and upon such  application,  Agent shall establish a Reserve against
the separate  Borrowing Base of the affected  Borrower in an amount equal to the
amount of such proceeds so applied. All insurance proceeds made available to any
Credit  Party  that is not a Borrower  to  replace,  repair,  restore or rebuild
Collateral  shall be deposited in a cash collateral  account.  Thereafter,  such
funds shall be made  available to that Borrower or Credit Party to provide funds
to replace,  repair,  restore or rebuild the Collateral as follows: (i) Borrower
Representative  shall request a Revolving  Credit  Advance or a release from the
cash  collateral  account be made to such Borrower or Credit Party in the amount
requested to be released;  (ii) so long as the  conditions  set forth in Section
2.2 have been met, Revolving


<PAGE>


Lenders shall make such  Revolving  Credit  Advance or Agent shall release funds
from the cash collateral  account;  and (iii) in the case of insurance  proceeds
applied against the Revolving Loan, the Reserve established with respect to such
insurance  proceeds  shall be  reduced by the  amount of such  Revolving  Credit
Advance.  To the  extent not used to  replace,  repair,  restore or rebuild  the
Collateral,  such insurance proceeds shall be applied in accordance with Section
1.3(c); provided that in the case of insurance proceeds pertaining to any Credit
Party that is not a Borrower,  such insurance  proceeds shall be applied ratably
to all of the Loans owing by each Borrower.

         5.5  Compliance  with Laws. (a) Each Credit Party shall comply with all
              ---------------------
federal, state, local, provincial and foreign laws and regulations of the United
States and Canada  applicable to it, ERISA and labor  matters and  Environmental
Laws and Environmental Permits, except to the extent that the failure to comply,
individually  or in the  aggregate,  could not  reasonably be expected to have a
Material Adverse Effect.

                  (b) For each existing Canadian Pension Plan, each Credit Party
shall  ensure  that  such  plan  retains  its  registered  status  under  and is
administered in a timely manner in all material  respects in accordance with the
applicable  pension  plan  text,  funding  agreement,  the  ITA  and  all  other
applicable laws.

                  (c) For each Canadian  Pension Plan  hereafter  adopted by any
Credit  Party  which is  required  to be  registered  under the ITA or any other
applicable  laws,  that  Credit  Party  shall use its best  efforts  to seek and
receive confirmation in writing from the applicable Governmental  Authorities to
the effect that such plan is  unconditionally  registered under the ITA and such
other applicable laws.

                  (d) For each  existing  Canadian  Pension  Plan  and  Canadian
Benefit Plan  hereafter  adopted,  each Credit  Party shall in a timely  fashion
perform in all material respects all obligations (including fiduciary,  funding,
investment  and  administration   obligations)   required  to  be  performed  in
connection with such plan and the funding media therefor.

                  (e) Each Credit  Party shall  deliver to Agent if requested by
Agent, promptly after the filing thereof by any Credit Party with any applicable
Governmental  Authority,  copies  of each  annual  and other  return,  report or
valuation  with respect to each Canadian  Pension Plan;  promptly  after receipt
thereof,  a copy of any  direction,  order,  notice,  ruling or opinion that any
Credit Party may receive from any applicable Governmental Authority with respect
to any Canadian Pension Plan; and  notification  within 30 days of any increases
having a cost to such  Credit  Party in excess of  C$250,000  per annum,  in the
benefits of any existing  Canadian Pension Plan or Canadian Benefit Plan, or the
establishment  of any new Canadian Pension Plan or Canadian Benefit Plan, or the
commencement of contributions to any such plan to which any Credit Party was not
previously contributing.

         5.6 Supplemental  Disclosure.  From time to time as may be requested by

completed  within  sixty  (60) days  prior to the date of  consummation  of such
Permitted Acquisition;

                           (vii)  the  business  and  assets  acquired  in  such

                  funding  of  all  Loans  in  connection  therewith,  and  such
                  Acquisition Pro Forma shall reflect that (x) average daily Net
                  Borrowing  Availability of all Borrowers for the 90-day period
                  preceding the consummation of such Permitted Acquisition would

                  connection  therewith  as if  made  on the  first  day of such
                  period)  and  the  Acquisition   Projections  (as  hereinafter

                  consummation of such Permitted  Acquisition,  and (y) on a pro
                  forma  basis,   no  Event  of  Default  has  occurred  and  is

                  covenants  set  forth in Annex G for the four  quarter  period
                  reflected  in  the   Compliance   Certificate   most  recently

                  therewith as if made on the first day of such period);

                  otherwise  prepared in accordance  with the  Projections  (the
                  "Acquisition Projections") and based upon historical financial
                  data of a recent  date  satisfactory  to  Agent,  taking  into
                  account such Permitted Acquisition; and

                  officer of Holdings or such other officer  acceptable to Agent
                  to the effect  that:  (w) each  Borrower  (after  taking  into
                  consideration  all rights of  contribution  and indemnity such
                  Borrower  has against  Holdings and each other  Subsidiary  of
                  Holdings)  will  be  Solvent  upon  the  consummation  of  the
                  Permitted  Acquisition;  (x) the  Acquisition Pro Forma fairly
                  presents the financial condition of Holdings and Borrowers (on
                  a  consolidated  basis) as of the date  thereof  after  giving
                  effect  to the  Permitted  Acquisition;  (y)  the  Acquisition
                  Projections are reasonable  estimates of the future  financial
                  performance  of Holdings and Borrowers  subsequent to the date
                  thereof  based upon the  historical  performance  of Holdings,
                  Borrowers  and the Target and show that Holdings and Borrowers
                  shall  continue  to  be  in  compliance   with  the  financial
                  covenants  set  forth in  Annex G for the one (1) year  period
                  thereafter;  and (z) Holdings  and  Borrowers  have  completed
                  their due diligence  investigation  with respect to the Target
                  and  such  Permitted  Acquisition,   which  investigation  was
                  conducted  in a manner  similar to that which  would have been
                  conducted by a prudent purchaser of a comparable  business and
                  the results of which investigation were delivered to Agent and
                  Lenders;

Except as otherwise expressly provided for in the Loan Documents, no termination

Amount  thereof,  if such  Indebtedness  is being  contested in accordance  with
Section  5.2(b),  to become  due prior to its  stated  maturity  or prior to its

of the Requisite  Lenders  shall),  without  notice,  suspend the Revolving Loan
facility with respect to additional Advances and/or the incurrence of additional
Letter  of  Credit  Obligations   whereupon  any  additional  Advances  and  the
incurrence of additional Letter of Credit  Obligations shall be made or extended
in Agent's sole discretion (or in the sole discretion of the Requisite  Lenders,
if such suspension occurred at their direction) so long as such Default or Event

Sections  8.1(g)  or (i),  the  Revolving  Loan  facility  shall be  immediately
terminated and all of the Obligations,  including the aggregate  Revolving Loan,

benefit of all valuation, appraisal, marshaling and exemption laws.

9.       ASSIGNMENT AND PARTICIPATIONS; APPOINTMENT OF AGENT

         9.1 Assignment  and  Participations.  (a) The Credit Parties  signatory
             -------------------------------
hereto consent to any Lender's  assignment of, and/or sale of participations in,
at any time or times, the Loan Documents,  Loans,  Letter of Credit  Obligations
and any Commitment or of any portion thereof or interest therein,  including any
Lender's  rights,  title,  interests,  remedies,  powers or  duties  thereunder,
whether  evidenced  by a writing or not.  Any  assignment  by a Lender shall (i)
require  the  consent of Agent  (which  shall not be  unreasonably  withheld  or
delayed)  and  the  execution  of  an  assignment   agreement  (an   "Assignment
Agreement")  substantially  in the form  attached  hereto as Exhibit  9.1(a) and
otherwise in form and substance  satisfactory  to, and  acknowledged  by, Agent;
(ii) be conditioned on such assignee Lender representing to the assigning Lender
and Agent that it is purchasing  the  applicable  Loans to be assigned to it for
its own account, for investment purposes and not with a view to the distribution
thereof;  (iii) if a  partial  assignment,  be in an  amount  at least  equal to
$5,000,000  and,  after  giving  effect  to any  such  partial  assignment,  the
assigning Lender shall have retained  Commitments in an amount at least equal to
$5,000,000;  and (iv) include a payment to Agent of an assignment fee of $3,500.
In the case


<PAGE>


of an assignment by a Lender under this Section 9.1, the assignee shall have, to
the extent of such assignment,  the same rights,  benefits and obligations as it
would if it were a Lender  hereunder.  The assigning Lender shall be relieved of
its obligations  hereunder with respect to its  Commitments or assigned  portion
thereof  from  and  after  the date of such  assignment.  Each  Borrower  hereby
acknowledges  and  agrees  that  any  assignment  will  give  rise  to a  direct
obligation  of  Borrowers  to the  assignee  and  that  the  assignee  shall  be
considered to be a "Lender".  In all instances,  each Lender's liability to make
Loans  hereunder  shall be  several  and not joint and shall be  limited to such
Lender's Pro Rata Share of the applicable Commitment.  In the event Agent or any
Lender assigns or otherwise transfers all or any part of the Obligations,  Agent
or any such Lender  shall so notify  Borrowers  and  Borrowers  shall,  upon the
request of Agent or such Lender, execute new Notes in exchange for the Notes, if
any, being assigned.  Notwithstanding  the foregoing  provisions of this Section
9.1(a),  any Lender may at any time pledge the  Obligations  held by it and such
Lender's  rights under this  Agreement and the other Loan Documents to a Federal
Reserve  Bank,  and any  Lender  that  is an  investment  fund  may  assign  the
Obligations  held by it and such  Lender's  rights under this  Agreement and the
other Loan Documents to another  investment  fund managed by the same investment
advisor; provided,  however, that no such pledge to a Federal Reserve Bank shall
release such Lender from such Lender's obligations  hereunder or under any other
Loan Document.

                  (b) Any  participation  by a Lender  of all or any part of its
Commitments  shall be made with the  understanding  that all amounts  payable by
Borrowers  hereunder  shall be  determined  as if that  Lender had not sold such
participation,  and  that the  holder  of any such  participation  shall  not be
entitled  to require  such  Lender to take or omit to take any action  hereunder
except actions directly  affecting (i) any reduction in the principal amount of,
or interest  rate or Fees payable with respect to, any Loan in which such holder
participates,  (ii) any  extension of the  scheduled  repayment of the principal
amount of any Loan in which such holder  participates or the final maturity date
thereof,  and (iii) any release of all or  substantially  all of the  Collateral
(other  than in  accordance  with the terms of this  Agreement,  the  Collateral
Documents or the other Loan  Documents).  Solely for purposes of Sections  1.12,
1.14, 1.15 and 9.8, each Borrower  acknowledges  and agrees that a participation
shall give rise to a direct  obligation of Borrowers to the  participant and the
participant  shall be  considered  to be a "Lender".  Except as set forth in the
preceding sentence no Borrower or Credit Party shall have any obligation or duty
to any participant.  Neither Agent nor any Lender (other than the Lender selling
a participation) shall have any duty to any participant and may continue to deal
solely with the Lender selling a participation as if no such sale had occurred.

                  (c) Except as  expressly  provided  in this  Section  9.1,  no
Lender shall, as between Borrowers and that Lender, or Agent and that Lender, be
relieved  of  any  of  its  obligations  hereunder  as a  result  of  any  sale,
assignment,  transfer or negotiation of, or granting of participation in, all or
any part of the Loans, the Notes or other Obligations owed to such Lender.

                  (d) Each Credit Party  executing this  Agreement  shall assist
any Lender  permitted to sell assignments or  participations  under this Section
9.1 as reasonably  required to enable the assigning or selling  Lender to effect
any such  assignment or  participation,  including the execution and delivery of
any and all agreements, notes and other documents and instruments


<PAGE>


as  shall  be  requested  and,  if  requested  by  Agent,   the  preparation  of
informational  materials  for, and the  participation  of management in meetings
with,  potential  assignees or  participants.  Each Credit Party  executing this
Agreement  shall  certify  the  correctness,  completeness  and  accuracy of all
descriptions  of the Credit  Parties and their affairs  contained in any selling
materials  provided  by them  and all  other  information  provided  by them and
included in such materials,  except that any Projections  delivered by Borrowers
shall only be certified  by  Borrowers  as having been  prepared by Borrowers in
compliance with the representations contained in Section 3.4(b).

                  (e) A Lender may furnish  any  information  concerning  Credit
Parties in the  possession  of such  Lender from time to time to  assignees  and
participants  (including  prospective  assignees and participants).  Each Lender
shall  obtain  from   assignees  or   participants   confidentiality   covenants
substantially equivalent to those contained in Section 11.8.

                  (f) So  long  as no  Event  of  Default  has  occurred  and is
continuing,  no Lender shall assign or sell participations in any portion of its
Loans or Commitments to a potential Lender or participant, if, as of the date of
the proposed  assignment or sale, the assignee  Lender or  participant  would be
subject to capital  adequacy  or similar  requirements  under  Section  1.15(a),
increased costs under Section 1.15(b),  or withholding  taxes in accordance with
Section 1.14(a).

         9.2  Appointment  of Agent.  GE Capital is hereby  appointed  to act on
              ---------------------
behalf  of all  Lenders  as  Agent  under  this  Agreement  and the  other  Loan
Documents.  The  provisions  of this  Section  9.2 are solely for the benefit of
Agent and Lenders and no Credit Party nor any other Person shall have any rights
as a third party beneficiary of any of the provisions  hereof. In performing its
functions and duties under this  Agreement and the other Loan  Documents,  Agent
shall act  solely as an agent of  Lenders  and does not  assume and shall not be
deemed to have assumed any obligation  toward or relationship of agency or trust
with or for any Credit Party or any other Person.  Agent shall have no duties or
responsibilities  except for those expressly set forth in this Agreement and the
other Loan Documents. The duties of Agent shall be mechanical and administrative
in nature  and Agent  shall  not have,  or be deemed to have,  by reason of this
Agreement,  any other Loan  Document or  otherwise a fiduciary  relationship  in
respect of any Lender.  Neither Agent nor any of its Affiliates nor any of their
respective officers,  directors,  employees,  agents or representatives shall be
liable to any Lender for any action taken or omitted to be taken by it hereunder
or under any other Loan Document, or in connection herewith or therewith, except
for damages caused by its or their own gross negligence or willful misconduct.

                  If Agent shall request  instructions from Requisite Lenders or
all affected  Lenders with  respect to any act or action  (including  failure to
act) in connection  with this Agreement or any other Loan  Document,  then Agent
shall be  entitled to refrain  from such act or taking  such  action  unless and
until Agent  shall have  received  instructions  from  Requisite  Lenders or all
affected Lenders, as the case may be, and Agent shall not incur liability to any
Person by reason of so refraining.  Agent shall be fully justified in failing or
refusing to take any action  hereunder  or under any other Loan  Document (a) if
such action would,  in the opinion of Agent,  be contrary to law or the terms of
this  Agreement or any other Loan  Document,  (b) if such action  would,  in the
opinion of Agent,  expose  Agent to  Environmental  Liabilities  or (c) if Agent
shall not first be indemnified to its satisfaction against any and all liability
and expense  which may be incurred  by it by reason of taking or  continuing  to
take any such action. Without limiting the foregoing,


<PAGE>


no Lender shall have any right of action whatsoever against Agent as a result of
Agent  acting or  refraining  from  acting  hereunder  or under  any other  Loan
Document  in  accordance  with the  instructions  of  Requisite  Lenders  or all
affected Lenders, as applicable.

         9.3 Agent's Reliance,  Etc. Neither Agent nor any of its Affiliates nor
             ----------------------
any of their respective directors, officers, agents or employees shall be liable
for any action taken or omitted to be taken by it or them under or in connection
with this  Agreement or the other Loan  Documents,  except for damages caused by
its or their own gross negligence or willful  misconduct.  Without limitation of
the generality of the foregoing,  Agent:  (a) may treat the payee of any Note as
the holder  thereof until Agent  receives  written  notice of the  assignment or
transfer thereof signed by such payee and in form satisfactory to Agent; (b) may
consult with legal counsel,  independent  public  accountants  and other experts
selected  by it and shall not be liable  for any  action  taken or omitted to be
taken  in good  faith  by it in  accordance  with the  advice  of such  counsel,
accountants or experts;  (c) makes no warranty or  representation  to any Lender
and shall not be  responsible  to any Lender for any  statements,  warranties or
representations  made in or in connection  with this Agreement or the other Loan
Documents;  (d) shall not have any duty to  ascertain  or to  inquire  as to the
performance  or observance of any of the terms,  covenants or conditions of this
Agreement  or the other Loan  Documents  on the part of any  Credit  Party or to
inspect the  Collateral  (including  the books and records) of any Credit Party;
(e) shall not be  responsible  to any  Lender for the due  execution,  legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
the other Loan Documents or any other instrument or document  furnished pursuant
hereto or thereto;  and (f) shall incur no liability under or in respect of this
Agreement  or the other  Loan  Documents  by acting  upon any  notice,  consent,
certificate or other instrument or writing (which may be by telecopy,  telegram,
cable or telex)  believed  by it to be genuine  and signed or sent by the proper
party or parties.

         9.4  GE  Capital  and  Affiliates.  With  respect  to  its  Commitments
              ----------------------------
hereunder, GE Capital shall have the same rights and powers under this Agreement
and the other Loan  Documents  as any other  Lender and may exercise the same as
though it were not Agent;  and the term  "Lender"  or  "Lenders"  shall,  unless
otherwise expressly indicated, include GE Capital in its individual capacity. GE
Capital and its Affiliates may lend money to, invest in, and generally engage in
any kind of business  with,  any Credit Party,  any of their  Affiliates and any
Person who may do business  with or own  securities  of any Credit  Party or any
such  Affiliate,  all as if GE Capital  were not Agent and  without  any duty to
account  therefor to Lenders.  GE Capital and its Affiliates may accept fees and
other  consideration  from any Credit Party for services in connection with this
Agreement or otherwise  without having to account for the same to Lenders.  Each
Lender  acknowledges the potential  conflict of interest between GE Capital as a
Lender, and GE Capital as Agent.

         9.5 Lender  Credit  Decision.  Each  Lender  acknowledges  that it has,
             ------------------------
independently  and without  reliance upon Agent or any other Lender and based on
the Financial  Statements referred to in Section 3.4(a) and such other documents
and information as it has deemed appropriate,  made its own credit and financial
analysis  of the  Credit  Parties  and its  own  decision  to  enter  into  this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance  upon  Agent  or any  other  Lender  and  based on such  documents  and
information as it shall deem  appropriate at the time,  continue to make its own
credit decisions in taking or not taking action


<PAGE>


under this  Agreement.  Each  Lender  acknowledges  the  potential  conflict  of
interest of each other  Lender as a result of Lenders  holding  disproportionate
interests in the Loans,  and  expressly  consents to, and waives any claim based
upon, such conflict of interest.

         9.6  Indemnification.  Lenders agree to indemnify  Agent (to the extent
              ---------------
not reimbursed by Credit Parties and without  limiting the obligations of Credit
Parties hereunder),  ratably according to their respective Pro Rata Shares, from
and against any and all liabilities,  obligations,  losses, damages,  penalties,
actions,  judgments,  suits,  costs,  expenses or  disbursements  of any kind or
nature  whatsoever  which may be imposed on,  incurred  by, or asserted  against
Agent in any way relating to or arising out of this  Agreement or any other Loan
Document  or any  action  taken or  omitted  by Agent in  connection  therewith;
provided,  however,  that no Lender  shall be  liable  for any  portion  of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or  disbursements  resulting  from Agent's gross  negligence or
willful  misconduct.  Without  limiting  the  foregoing,  each Lender  agrees to
reimburse Agent promptly upon demand for its ratable share of any  out-of-pocket
expenses  (including  counsel  fees)  incurred by Agent in  connection  with the
preparation,  execution, delivery,  administration,  modification,  amendment or
enforcement (whether through  negotiations,  legal proceedings or otherwise) of,
or legal advice in respect of rights or  responsibilities  under, this Agreement
and each other Loan  Document,  to the extent that Agent is not  reimbursed  for
such expenses by Credit Parties.

         9.7  Successor  Agent.  Agent may resign at any time by giving not less
              ----------------
than thirty  (30) days' prior  written  notice  thereof to Lenders and  Borrower
Representative.  Upon any such resignation, the Requisite Lenders shall have the
right to appoint a successor  Agent.  If no  successor  Agent shall have been so
appointed by the  Requisite  Lenders and shall have  accepted  such  appointment
within 30 days after the resigning  Agent's giving notice of  resignation,  then
the resigning Agent may, on behalf of Lenders,  appoint a successor Agent, which
shall be a  Lender,  if a Lender  is  willing  to accept  such  appointment,  or
otherwise shall be a commercial bank or financial institution or a subsidiary of
a commercial bank or financial  institution if such commercial bank or financial
institution  is organized  under the laws of the United  States of America or of
any  State  thereof  and  has  a  combined  capital  and  surplus  of  at  least
$300,000,000.  If  no  successor  Agent  has  been  appointed  pursuant  to  the
foregoing,  by the 30th day after the date such notice of resignation  was given
by the  resigning  Agent,  such  resignation  shall  become  effective  and  the
Requisite  Lenders shall  thereafter  perform all the duties of Agent  hereunder
until such time, if any, as the Requisite  Lenders  appoint a successor Agent as
provided above.  Any successor Agent  appointed by Requisite  Lenders  hereunder
shall be subject to the approval of Borrower  Representative,  such approval not
to be unreasonably withheld or delayed; provided that such approval shall not be
required if a Default or an Event of Default  has  occurred  and is  continuing.
Upon the acceptance of any appointment as Agent hereunder by a successor  Agent,
such  successor  Agent shall  succeed to and become  vested with all the rights,
powers,  privileges and duties of the resigning  Agent.  Upon the earlier of the
acceptance of any  appointment  as Agent  hereunder by a successor  Agent or the
effective date of the resigning Agent's  resignation,  the resigning Agent shall
be discharged from its duties and obligations under this Agreement and the other
Loan  Documents,  except that any  indemnity  rights or other rights in favor of
such resigning Agent shall  continue.  After any resigning  Agent's  resignation
hereunder, the provisions of this Section 9 shall inure to its benefit as to any
actions  taken or omitted  to be taken by it while it was acting as Agent  under
this Agreement and the other Loan Documents.

         9.8 Setoff and  Sharing of  Payments.  In addition to any rights now or
             --------------------------------
hereafter  granted under applicable law and not by way of limitation of any such
rights,  upon the occurrence and during the continuance of any Event of Default,
and subject to Section 9.9(f),  each Lender is hereby  authorized at any time or
from time to time,  without  notice to any Credit Party or to any other  Person,
any such notice being hereby expressly waived to the fullest extent permitted by
law, to offset and to  appropriate  and to apply any and all balances held by it
at any of its offices for the account of any Borrower or  Guarantor  (regardless
of whether such  balances are then due to such  Borrower or  Guarantor)  and any
other  properties or assets any time held or owing by that Lender or that holder
to or for the credit or for the account of any Borrower or Guarantor against and
on account of any of the Obligations  which are not paid when due. Any Lender or
holder  of any Note  exercising  a right to offset or  otherwise  receiving  any
payment on account of the  Obligations  in excess of its Pro Rata Share  thereof
shall  purchase  for cash (and the other  Lenders  or holders  shall  sell) such
participations  in each such other  Lender's or  holder's  Pro Rata Share of the
Obligations  as would be  necessary  to cause such Lender to share the amount so
offset or otherwise received with each other Lender or holder in accordance with
their  respective  Pro Rata Shares  (other than offset  rights  exercised by any
Lender with respect to Sections 1.12, 1.14 and 1.15).  Each Credit Party that is
a Borrower or Guarantor  agrees,  that (a) any Lender or holder may exercise its
right to offset  with  respect to amounts in excess of its Pro Rata Share of the
Obligations  and may sell  participations  in such  amount  so  offset  to other
Lenders and holders and (b) any Lender or holders so purchasing a  participation
in the Loans made or other  Obligations  held by other  Lenders  or holders  may
exercise all rights of offset,  bankers'  lien,  counterclaim  or similar rights
with respect to such  participation  as fully as if such Lender or holder were a
direct  holder  of the Loans and the  other  Obligations  in the  amount of such
participation.  Notwithstanding  the  foregoing,  if all or any  portion  of the
offset amount or payment  otherwise  received is thereafter  recovered  from the
Lender that has exercised the right of offset, the purchase of participations by
that Lender shall be rescinded and the purchase price restored without interest.

         9.9 Advances; Payments;  Non-Funding Lenders;  Information;  Actions in
             -------------------------------------------------------------------
Concert.
- -------

                  (a)  Advances;  Payments.  (i) Agent  shall  notify  Revolving
                       -------------------
Lenders,  promptly after receipt of a Notice of Revolving  Credit Advance and in
any  event  prior to 1:00  p.m.  (New  York  time) on the date  such  Notice  of
Revolving Advance is received,  by telecopy,  telephone or other similar form of
transmission.  Each Revolving  Lender shall make the amount of such Lender's Pro
Rata Share of such Revolving Credit Advance available to Agent in same day funds
by wire transfer to Agent's  account as set forth in Annex H not later than 3:00
p.m. (New York time) on the requested funding date, in the case of an Index Rate
Loan or BA Rate Loan, as the case may be. After  receipt of such wire  transfers
(or, in the Agent's sole  discretion,  before  receipt of such wire  transfers),
subject to the terms  hereof,  Agent shall make the requested  Revolving  Credit
Advance to the Borrower  designated by Borrower  Representative in the Notice of
Revolving  Credit Advance.  All payments by each Revolving  Lender shall be made
without setoff, counterclaim or deduction of any kind.

                           (ii)  On  the  second  (2nd)  Business  Day  of  each
calendar week or more frequently as aggregate  cumulative  payments in excess of
$2,000,000 are received with respect to the Loans (each,  a "Settlement  Date"),
Agent will advise each Lender by telephone, or telecopy


<PAGE>


of the amount of such  Lender's Pro Rata Share of  principal,  interest and Fees
paid for the benefit of Lenders with respect to each applicable  Loan.  Provided
that such Lender has funded all  payments or Advances  required to be made by it
and has purchased all  participations  required to be purchased by it under this
Agreement and the other Loan Documents as of such  Settlement  Date,  Agent will
pay to each Lender such Lender's Pro Rata Share of principal,  interest and Fees
paid by  Borrowers  since the previous  Settlement  Date for the benefit of that
Lender on the Loans  held by it. To the extent  that any Lender (a  "Non-Funding
Lender") has failed to fund all such payments and Advances or failed to fund the
purchase  of all such  participations,  Agent  shall be  entitled to set off the
funding  short-fall  against  that  Non-Funding  Lender's  Pro Rata Share of all
payments  received from Borrowers.  Such payments shall be made by wire transfer
to such  Lender's  account  (as  specified  by  such  Lender  in  Annex H or the
applicable Assignment Agreement) not later than 2:00 p.m. (New York time) on the
next Business Day following each Settlement Date.

                  (b) Availability of Lender's Pro Rata Share.  Agent may assume
that each Revolving Lender will make its Pro Rata Share of each Revolving Credit
Advance  available to Agent on each funding date. If such Pro Rata Share is not,
in fact, paid to Agent by such Revolving Lender when due, Agent will be entitled
to recover such amount on demand from such  Revolving  Lender  without  set-off,
counterclaim or deduction of any kind. If any Revolving  Lender fails to pay the
amount of its Pro Rata Share forthwith upon Agent's demand, Agent shall promptly
notify Borrower Representative and Borrowers shall immediately repay such amount
to Agent.  Nothing in this Section  9.9(b) or elsewhere in this Agreement or the
other Loan Documents shall be deemed to require Agent to advance funds on behalf
of any Revolving  Lender or to relieve any Revolving  Lender from its obligation
to fulfill its  Commitments  hereunder or to prejudice any rights that Borrowers
may have  against  any  Revolving  Lender  as a result  of any  default  by such
Revolving  Lender  hereunder.  To the extent  that Agent  advances  funds to any
Borrower on behalf of any Revolving Lender and is not reimbursed therefor on the
same Business Day as such Advance is made, Agent shall be entitled to retain for
its  account  all  interest  accrued on such  Advance  until  reimbursed  by the
applicable Revolving Lender.

                  (c)  Return  of  Payments.  (i) If Agent  pays an  amount to a
Lender under this Agreement in the belief or expectation  that a related payment
has been or will be received by Agent from Borrowers and such related payment is
not  received by Agent,  then Agent will be entitled to recover such amount from
such Lender on demand without set-off, counterclaim or deduction of any kind.

                           (ii) If Agent  determines at any time that any amount
received by Agent under this  Agreement must be returned to any Borrower or paid
to  any  other  Person  pursuant  to any  insolvency  law  or  otherwise,  then,
notwithstanding  any other term or condition of this Agreement or any other Loan
Document,  Agent will not be required to distribute  any portion  thereof to any
Lender.  In  addition,  each Lender will repay to Agent on demand any portion of
such amount that Agent has distributed to such Lender, together with interest at
such rate,  if any, as Agent is  required  to pay to any  Borrower or such other
Person, without set-off, counterclaim or deduction of any kind.


<PAGE>


                  (d) Non-Funding Lenders. The failure of any Non-Funding Lender
                      -------------------
to make any  Revolving  Credit  Advance or any payment  required by it hereunder
shall not relieve any other Revolving Lender (each such other Revolving  Lender,
an "Other  Lender") of its  obligations  to make such  Advance or purchase  such
participation  on such date,  but  neither  any Other  Lender nor Agent shall be
responsible for the failure of any  Non-Funding  Lender to make an Advance or to
purchase  a  participation  or  make  any  other  payment  required   hereunder.
Notwithstanding  anything set forth herein to the contrary, a Non-Funding Lender
shall not have any voting or consent  rights  under or with  respect to any Loan
Document or constitute a "Lender" or a "Revolving Lender" (or be included in the
calculation of "Requisite  Lenders"  hereunder) for any voting or consent rights
under or with respect to any Loan Document.

                  (e)  Dissemination  of Information.  Agent will use reasonable
                       -----------------------------
efforts  to  provide  Lenders  with any  notice of  Default  or Event of Default
received by Agent from, or delivered by Agent to, any Credit Party,  with notice
of any Event of Default of which Agent has actually become aware and with notice
of any action taken by Agent following any Event of Default; provided,  however,
that Agent shall not be liable to any Lender for any failure to do so, except to
the extent that such failure is  attributable  to Agent's  gross  negligence  or
willful  misconduct.  Lenders acknowledge that Borrowers are required to provide
Financial  Statements  and  Collateral  Reports to Lenders  in  accordance  with
Annexes E and F hereto and agree that  Agent  shall have no duty to provide  the
same to Lenders.

                  (f) Actions in  Concert.  Anything  in this  Agreement  to the
                      -------------------
contrary notwithstanding,  each Lender hereby agrees with each other Lender that
no Lender shall take any action to protect or enforce its rights  arising out of
this Agreement or the Notes (including exercising any rights of set-off) without
first  obtaining the prior written  consent of Agent and Requisite  Lenders,  it
being the intent of Lenders  that any such  action to protect or enforce  rights
under  this  Agreement  and the  Notes  shall  be taken  in  concert  and at the
direction or with the consent of Agent.

10.      SUCCESSORS AND ASSIGNS

         10.1  Successors  and  Assigns.  This  Agreement  and  the  other  Loan
               ------------------------
Documents  shall be binding  on and shall  inure to the  benefit of each  Credit
Party, Agent, Lenders and their respective successors and assigns (including, in
the case of any Credit Party,  a  debtor-in-possession  on behalf of such Credit
Party),  except as  otherwise  provided  herein or therein.  No Credit Party may
assign,  transfer,   hypothecate  or  otherwise  convey  its  rights,  benefits,
obligations or duties hereunder or under any of the other Loan Documents without
the prior  express  written  consent of Agent and  Lenders.  Any such  purported
assignment,  transfer,  hypothecation  or other  conveyance  by any Credit Party
without the prior  express  written  consent of Agent and Lenders shall be void.
The terms and  provisions of this  Agreement are for the purpose of defining the
relative  rights and  obligations  of each Credit Party,  Agent and Lenders with
respect to the transactions  contemplated  hereby and no Person shall be a third
party beneficiary of any of the terms and provisions of this Agreement or any of
the other Loan Documents.

         11.1 Complete Agreement;  Modification of Agreement. The Loan Documents
              ----------------------------------------------

subject matter thereof and may not be modified, altered or amended except as set
forth in Section 11.2 below.  Any letter of interest,  commitment  letter and/or
fee letter  (other than the GE Capital Fee Letter)  between any Credit Party and
Agent  or any  Lender  or any of their  respective  Affiliates,  predating  this
Agreement and relating to a financing of substantially  similar form, purpose or
effect shall be superseded by this Agreement.

         11.2 Amendments and Waivers. (a) Except for actions expressly permitted
              ----------------------
to be taken by Agent, no amendment,  modification,  termination or waiver of any
provision of this  Agreement or any other Loan  Document,  or any consent to any
departure by any Credit Party therefrom,  shall in any event be effective unless
the same shall be in writing and signed by Agent and Borrowers, and by Requisite
Lenders or all affected Lenders,  as applicable.  Except as set forth in clauses
(b) and (c) below, all such amendments,  modifications,  terminations or waivers
requiring  the consent of any  Lenders  shall  require  the  written  consent of
Requisite Lenders.

                  (b) No amendment,  modification,  termination  or waiver of or
consent with respect to any  provision of this  Agreement  which  increases  the
percentage  advance rates set forth in the definition of the Domestic  Borrowers
Borrowing Base, or AEC Funding  Borrowing Base, or which makes less  restrictive
the nondiscretionary  criteria for exclusion from Eligible Accounts set forth in
Section 1.6,  shall be effective  unless the same shall be in writing and signed
by  Agent,  Requisite  Lenders  and  Borrowers.   No  amendment,   modification,
termination  or waiver of or  consent  with  respect  to any  provision  of this
Agreement  which waives  compliance  with the conditions  precedent set forth in
Section 2.2 to the making of any Loan or the  incurrence of any Letter of Credit
Obligations shall be effective unless the same shall be in writing and signed by
Agent,  Requisite Lenders and Borrowers.  Notwithstanding  anything contained in
this Agreement to the contrary, no waiver or consent with respect to any Default
(if in connection therewith Agent or Requisite Lenders, as the case may be, have
exercised  its or their  right to suspend  the making or  incurrence  of further
Advances  or Letter of Credit  Obligations  pursuant  to Section  8.2(a)) or any
Event of Default shall be effective for purposes of the conditions  precedent to
the making of Loans or the incurrence of Letter of Credit  Obligations set forth
in  Section  2.2  unless  the same  shall be in  writing  and  signed  by Agent,
Requisite Lenders and Borrowers.

                  (c) No amendment,  modification,  termination or waiver shall,
unless in writing and signed by Agent and each Lender directly affected thereby,
do any of the  following:  (i)  increase  the  principal  amount of any Lender's
Commitment  (which action shall be deemed to directly affect all Lenders);  (ii)
reduce the principal of, rate of interest on or Fees payable with respect to any
Loan or Letter of Credit  Obligations of any affected  Lender;  (iii) extend any
scheduled  payment date or final  maturity date of the  principal  amount of any
Loan of any affected Lender; (iv) waive, forgive,  defer, extend or postpone any
payment of interest or Fees as to any affected Lender;  (v) release any Guaranty
or,  except  as  otherwise  permitted  herein or in the  other  Loan  Documents,
release,  or permit  any  Credit  Party to sell or  otherwise  dispose  of,  any
Collateral  with a value  exceeding  $5,000,000 in the  aggregate  (which action
shall be deemed to directly  affect all Lenders);  (vi) change the percentage of
the Commitments or of the aggregate


<PAGE>


unpaid  principal amount of the Loans which shall be required for Lenders or any
of them to take any action hereunder; and (vii) amend or waive this Section 11.2
or the definitions of the term "Requisite  Lenders"  insofar as such definitions
affect  the  substance  of  this  Section  11.2.   Furthermore,   no  amendment,
modification,  termination  or waiver  affecting  the  rights or duties of Agent
under this  Agreement or any other Loan  Document  shall be effective  unless in
writing and signed by Agent, in addition to Lenders required hereinabove to take
such  action.  Each  amendment,  modification,  termination  or waiver  shall be
effective only in the specific  instance and for the specific  purpose for which
it was  given.  No  amendment,  modification,  termination  or  waiver  shall be
required for Agent to take additional  Collateral pursuant to any Loan Document.
No amendment,  modification,  termination or waiver of any provision of any Note
shall be effective  without the written  concurrence of the holder of that Note.
No notice to or demand on any Credit Party in any case shall entitle such Credit
Party or any  other  Credit  Party to any other or  further  notice or demand in
similar or other circumstances. Any amendment, modification, termination, waiver
or consent  effected in accordance  with this Section 11.2 shall be binding upon
each holder of the Notes at the time  outstanding  and each future holder of the
Notes.

                  (d)  If,   in   connection   with  any   proposed   amendment,
modification, waiver or termination (a "Proposed Change"):

                           (i)  requiring  the consent of all affected  Lenders,
the consent of Requisite  Lenders is obtained,  but the consent of other Lenders
whose  consent is required is not obtained (any such Lender whose consent is not
obtained as described this clause (i) and in clauses (ii),  (iii) and (iv) below
being referred to as a "Non-Consenting Lender"), or

                           (ii) requiring the consent of Requisite Lenders,  the
consent  of  Lenders  holding  51% or  more  of  the  aggregate  Revolving  Loan
Commitments is obtained, but the consent of Requisite Lenders is not obtained,

then,  so  long  as  Agent  is  not  a   Non-Consenting   Lender,   at  Borrower
Representative's  request,  Agent or a Person acceptable to Agent shall have the
right with  Agent's  consent and in Agent's sole  discretion  (but shall have no
obligation)   to   purchase   from  such   Non-Consenting   Lenders,   and  such
Non-Consenting  Lenders agree that they shall,  upon Agent's  request,  sell and
assign to Agent or such Person,  all of the  Commitments of such  Non-Consenting
Lender  for an amount  equal to the  principal  balance of all Loans held by the
Non-Consenting  Lender and all accrued  interest and Fees with  respect  thereto
through the date of sale,  such purchase and sale to be consummated  pursuant to
an executed Assignment Agreement.

                  (e) Upon indefeasible  payment in full in cash and performance
of all of the Obligations (other than indemnification  Obligations under Section
1.12),  termination of the Commitments and a release of all claims against Agent
and  Lenders,  and so long as no suits,  actions,  proceedings,  or  claims  are
pending or  threatened  against any  Indemnified  Person  asserting any damages,
losses or liabilities that are Indemnified  Liabilities,  Agent shall deliver to
Borrowers  termination   statements,   mortgage  releases  and  other  documents
necessary or  appropriate  to evidence  the  termination  of the Liens  securing
payment of the Obligations.

              ---------
to require  strict  performance  by the Credit  Parties of any provision of this
Agreement  and any of the  other  Loan  Documents  shall  not  waive,  affect or
diminish  any  right  of  Agent  or such  Lender  thereafter  to  demand  strict
compliance and  performance  therewith.  Any suspension or waiver of an Event of
Default  shall not suspend,  waive or affect any other Event of Default  whether
the same is prior or  subsequent  thereto and whether the same or of a different
type.  Subject to the  provisions  of Section  11.2,  none of the  undertakings,
agreements,  warranties,  covenants  and  representations  of any  Credit  Party
contained in this Agreement or any of the other Loan Documents and no Default or
Event of Default by any Credit  Party shall be deemed to have been  suspended or
waived  by Agent or any  Lender,  unless  such  waiver  or  suspension  is by an
instrument in writing  signed by an officer of or other  authorized  employee of
Agent and the applicable required Lenders,  and directed to Borrowers specifying
such suspension or waiver.

         11.5  Remedies.  Agent's and Lenders'  rights and  remedies  under this

other  Loan  Documents,  by  operation  of law  or  otherwise.  Recourse  to the
Collateral shall not be required.

         11.6 Severability.  Wherever possible, each provision of this Agreement
              ------------
and the other  Loan  Documents  shall be  interpreted  in such a manner as to be
effective and valid under applicable law, but if any provision of this Agreement
or any other Loan Document  shall be  prohibited by or invalid under  applicable
law, such provision  shall be  ineffective to the extent of such  prohibition or
invalidity,  without  invalidating  the  remainder  of  such  provision  or  the
remaining provisions of this Agreement.

         11.7 Conflict of Terms.  Except as otherwise provided in this Agreement
              -----------------
or any of the other Loan  Documents  by  specific  reference  to the  applicable
provisions  of this  Agreement,  if any  provision  contained in this  Agreement
conflicts with any provision in any of the other Loan  Documents,  the provision
contained in this Agreement shall govern and control.

         11.8  Confidentiality.  Agent and each Lender agree to use commercially
               ---------------
reasonable  efforts  (equivalent  to the efforts Agent or such Lender applies to
maintaining the confidentiality of its own confidential information) to maintain
as  confidential  all  confidential  information  provided to them by the Credit
Parties and designated as  confidential  for a period of two (2) years following
receipt thereof,  except that Agent and any Lender may disclose such information
(a) to  Persons  employed  or  engaged  by Agent or such  Lender in  evaluating,
approving,  structuring or administering  the Loans and the Commitments;  (b) to
any bona fide assignee or


<PAGE>


participant or potential  assignee or participant that has agreed to comply with
the covenant  contained in this Section 11.8 (and any such bona fide assignee or
participant or potential  assignee or participant may disclose such  information
to Persons employed or engaged by them as described in clause (a) above); (c) as
required or requested by any  Governmental  Authority or reasonably  believed by
Agent or such Lender to be compelled by any court  decree,  subpoena or legal or
administrative  order or  process;  (d) as,  on the  advice of  Agent's  or such
Lender's  counsel,  required by law; (e) in connection  with the exercise of any
right or remedy under the Loan Documents or in connection with any Litigation to
which Agent or such Lender is a party;  or (f) which  ceases to be  confidential
through no fault of Agent or such Lender.

         11.9 GOVERNING LAW.  EXCEPT AS OTHERWISE  EXPRESSLY  PROVIDED IN ANY OF
              -------------
THE LOAN  DOCUMENTS,  IN ALL RESPECTS,  INCLUDING  ALL MATTERS OF  CONSTRUCTION,
VALIDITY  AND  PERFORMANCE,  THE LOAN  DOCUMENTS  AND THE  OBLIGATIONS  SHALL BE
GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF
THE STATE OF NEW YORK  APPLICABLE TO CONTRACTS  MADE AND PERFORMED IN THAT STATE
AND ANY  APPLICABLE  LAWS OF THE UNITED  STATES OF AMERICA.  EACH  CREDIT  PARTY
HEREBY  CONSENTS AND AGREES THAT THE STATE OR FEDERAL COURTS LOCATED IN NEW YORK
COUNTY, CITY OF NEW YORK, NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND
DETERMINE ANY CLAIMS OR DISPUTES  BETWEEN THE CREDIT PARTIES,  AGENT AND LENDERS
PERTAINING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY MATTER
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS,
PROVIDED,  THAT  AGENT,  LENDERS  AND THE CREDIT  PARTIES  ACKNOWLEDGE  THAT ANY
APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW
YORK COUNTY,  CITY OF NEW YORK, NEW YORK AND, PROVIDED,  FURTHER NOTHING IN THIS
AGREEMENT  SHALL BE DEEMED OR OPERATE TO PRECLUDE  AGENT FROM  BRINGING  SUIT OR
TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE COLLATERAL
OR ANY OTHER  SECURITY  FOR THE  OBLIGATIONS,  OR TO ENFORCE A JUDGMENT OR OTHER
COURT ORDER IN FAVOR OF AGENT.  EACH CREDIT PARTY EXPRESSLY SUBMITS AND CONSENTS
IN ADVANCE TO SUCH  JURISDICTION  IN ANY  ACTION OR SUIT  COMMENCED  IN ANY SUCH
COURT, AND EACH CREDIT PARTY HEREBY WAIVES ANY OBJECTION WHICH SUCH CREDIT PARTY
MAY HAVE BASED UPON LACK OF PERSONAL  JURISDICTION,  IMPROPER VENUE OR FORUM NON
CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF
AS IS DEEMED APPROPRIATE BY SUCH COURT. EACH CREDIT PARTY HEREBY WAIVES PERSONAL
SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR
SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS,  COMPLAINTS  AND OTHER PROCESS MAY
BE MADE BY  REGISTERED OR CERTIFIED  MAIL  ADDRESSED TO SUCH CREDIT PARTY AT THE

provided herein that any notice, demand, request, consent, approval, declaration
or  other  communication  shall or may be  given  to or  served  upon any of the
parties by any other parties,  or whenever any of the parties desires to give or
serve upon any other parties any  communication  with respect to this Agreement,
each such notice,  demand,  request,  consent,  approval,  declaration  or other
communication  shall be in  writing  and shall be  deemed  to have been  validly
served,  given or delivered (a) upon the earlier of actual receipt and three (3)

The  giving of any  notice  required  hereunder  may be waived in writing by the

         11.11  Section  Titles.  The  Section  titles  and  Table  of  Contents
                ---------------
contained  in this  Agreement  are and shall be without  substantive  meaning or
content of any kind  whatsoever and are not a part of the agreement  between the
parties hereto.

         11.12  Counterparts.  This  Agreement  may be executed in any number of
                ------------
separate   counterparts,   each  of  which  shall  collectively  and  separately
constitute one agreement.

         11.13 WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION WITH
               --------------------
COMPLEX FINANCIAL  TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE  STATE AND FEDERAL
LAWS TO APPLY (RATHER THAN  ARBITRATION  RULES),  THE PARTIES  DESIRE THAT THEIR
DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH  APPLICABLE  LAWS.  THEREFORE,  TO
ACHIEVE  THE BEST  COMBINATION  OF THE  BENEFITS OF THE  JUDICIAL  SYSTEM AND OF
ARBITRATION,  THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
SUIT,  OR  PROCEEDING  BROUGHT TO  RESOLVE  ANY  DISPUTE,  WHETHER  SOUNDING  IN
CONTRACT,  TORT OR OTHERWISE,  AMONG AGENT, LENDERS AND ANY CREDIT PARTY ARISING

affiliates or referring to this Agreement or the other Loan


<PAGE>


Documents without at least two (2) Business Days' prior notice to GE Capital and
without the prior written  consent of GE Capital  unless (and only to the extent
that) such Credit Party or Affiliate is required to do so under law and then, in
any event,  such Credit Party or Affiliate  will consult with GE Capital  before
issuing  such press  release  or other  public  disclosure.  Each  Credit  Party
consents to the  publication  by Agent or any Lender of a  tombstone  or similar
advertising material relating to the financing transactions contemplated by this
Agreement.  Agent or such Lender shall provide a draft of any such  tombstone or
similar  advertising  material to each Credit Party for review and comment prior
to the  publication  thereof.  Agent  reserves  the right to provide to industry
trade organizations  information necessary and customary for inclusion in league
table  measurements  with  Borrowers'  consent  which shall not be  unreasonably
withheld or delayed.

         11.15  Reinstatement.  This  Agreement  shall  remain in full force and
                -------------
effect and continue to be  effective  should any petition be filed by or against
any Borrower  for  liquidation  or  reorganization,  should any Borrower  become
insolvent or make an assignment  for the benefit of any creditor or creditors or
should a receiver or trustee be appointed for all or any significant part of any
Borrower's  assets,  and shall continue to be effective or to be reinstated,  as
the case may be, if at any time payment and performance of the  Obligations,  or
any part  thereof,  is,  pursuant to  applicable  law,  rescinded  or reduced in
amount,  or must  otherwise  be  restored  or  returned  by any  obligee  of the
Obligations,  whether as a "voidable  preference,"  "fraudulent  conveyance," or
otherwise,  all as though such payment or performance  had not been made. In the
event that any payment, or any part thereof, is rescinded,  reduced, restored or
returned,  the  Obligations  shall be reinstated and deemed reduced only by such
amount paid and not so rescinded, reduced, restored or returned.

         11.16 Advice of Counsel.  Each of the parties  represents to each other
               -----------------
party  hereto  that it has  discussed  this  Agreement  and,  specifically,  the
provisions of Sections 11.9 and 11.13, with its counsel.

         11.17 No Strict  Construction.  The parties  hereto  have  participated
               -----------------------
jointly in the  negotiation  and  drafting  of this  Agreement.  In the event an
ambiguity or question of intent or interpretation  arises,  this Agreement shall
be construed as if drafted  jointly by the parties  hereto and no presumption or
burden of proof shall arise favoring or  disfavoring  any party by virtue of the
authorship of any provisions of this Agreement.

12.      CROSS-GUARANTY

         12.1 Cross-Guaranty.  Each Borrower hereby agrees that such Borrower is
              --------------
jointly and  severally  liable for, and hereby  absolutely  and  unconditionally
guarantees to Agent and Lenders and their respective successors and assigns, the
full and  prompt  payment  (whether  at  stated  maturity,  by  acceleration  or
otherwise) and performance of, all Obligations  owed or hereafter owing to Agent
and Lenders by each other  Borrower.  Each  Borrower  agrees  that its  guaranty
obligation hereunder is a continuing guaranty of payment and performance and not
of  collection,  that  its  obligations  under  this  Section  12  shall  not be
discharged  until  payment and  performance,  in full,  of the  Obligations  has
occurred,  and that its obligations  under this Section 12 shall be absolute and
unconditional, irrespective of, and unaffected by,


<PAGE>


                  (a) the genuineness,  validity, regularity,  enforceability or
any future  amendment of, or change in, this Agreement,  any other Loan Document
or any other  agreement,  document or instrument to which any Borrower is or may
become a party;

                  (b) the  absence  of any  action  to  enforce  this  Agreement
(including  this Section 12) or any other Loan Document or the waiver or consent
by Agent and Lenders with respect to any of the provisions thereof;

                  (c) the  existence,  value or  condition  of,  or  failure  to
perfect its Lien against, any security for the Obligations or any action, or the
absence of any action,  by Agent and Lenders in respect  thereof  (including the
release of any such security);

                  (d) the insolvency of any Credit Party; or

                  (e) any other action or  circumstances  which might  otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor.

Each Borrower shall be regarded, and shall be in the same position, as principal
debtor with respect to the Obligations guaranteed hereunder.

         12.2 Waivers by Borrowers. Each Borrower expressly waives all rights it
              --------------------
may have now or in the future under any statute,  or at common law, or at law or
in equity,  or  otherwise,  to compel Agent or Lenders to marshall  assets or to
proceed in respect of the  Obligations  guaranteed  hereunder  against any other
Credit  Party,  any other  party or against  any  security  for the  payment and
performance of the Obligations before proceeding  against,  or as a condition to
proceeding against, such Borrower.  It is agreed among each Borrower,  Agent and
Lenders  that  the  foregoing  waivers  are of the  essence  of the  transaction
contemplated  by this  Agreement and the other Loan  Documents and that, but for
the  provisions  of this Section 12 and such  waivers,  Agent and Lenders  would
decline to enter into this Agreement.

         12.3 Benefit of Guaranty.  Each Borrower  agrees that the provisions of
              -------------------
this  Section 12 are for the benefit of Agent and  Lenders and their  respective
successors,  transferees,  endorsees and assigns,  and nothing herein  contained
shall  impair,  as  between  any  other  Borrower  and  Agent  or  Lenders,  the
obligations of such other Borrower under the Loan Documents.

         12.4 Subordination of Subrogation, Etc. Notwithstanding anything to the
              ---------------------------------
contrary  in this  Agreement  or in any other Loan  Document,  and except as set
forth  in  Section  12.7,  each  Borrower   hereby   expressly  and  irrevocably
subordinates  to  payment  of the  Obligations  any and all  rights at law or in
equity to subrogation, reimbursement, exoneration, contribution, indemnification
or set off  and  any  and all  defenses  available  to a  surety,  guarantor  or
accommodation  co-obligor until the Obligations are indefeasibly paid in full in
cash. Each Borrower  acknowledges and agrees that this subordination is intended
to  benefit  Agent and  Lenders  and shall not limit or  otherwise  affect  such
Borrower's  liability  hereunder or the  enforceability  of this Section 12, and
that Agent,  Lenders and their  respective  successors  and assigns are intended
third  party  beneficiaries  of the  waivers  and  agreements  set forth in this
Section 12.4.


<PAGE>


         12.5 Election of Remedies. If Agent or any Lender may, under applicable
              --------------------
law,  proceed to realize its  benefits  under any of the Loan  Documents  giving
Agent or such Lender a Lien upon any  Collateral,  whether owned by any Borrower
or by any other Person,  either by judicial  foreclosure or by non-judicial sale
or enforcement,  Agent or any Lender may, at its sole option, determine which of
its  remedies or rights it may pursue  without  affecting  any of its rights and
remedies  under this  Section  12. If, in the  exercise of any of its rights and
remedies,  Agent or any Lender  shall  forfeit  any of its  rights or  remedies,
including its right to enter a deficiency  judgment  against any Borrower or any
other Person,  whether because of any applicable laws pertaining to "election of
remedies" or the like,  each Borrower hereby consents to such action by Agent or
such Lender and waives any claim based upon such action,  even if such action by
Agent or such  Lender  shall  result in a full or partial  loss of any rights of
subrogation  which each Borrower might otherwise have had but for such action by
Agent or such Lender.  Any election of remedies  which  results in the denial or
impairment  of the right of Agent or any  Lender to seek a  deficiency  judgment
against any Borrower shall not impair any other Borrower's obligation to pay the
full amount of the  Obligations.  In the event Agent or any Lender  shall bid at
any foreclosure or trustee's sale or at any private sale permitted by law or the
Loan Documents,  Agent or such Lender may bid all or less than the amount of the
Obligations  and the amount of such bid need not be paid by Agent or such Lender
but shall be credited against the Obligations.  The amount of the successful bid
at any such sale,  whether  Agent,  Lender or any other party is the  successful
bidder,  shall  be  conclusively  deemed  to be the  fair  market  value  of the
Collateral and the difference  between such bid amount and the remaining balance
of  the  Obligations  shall  be  conclusively  deemed  to be the  amount  of the
Obligations  guaranteed under this Section 12,  notwithstanding that any present
or future law or court  decision or ruling may have the effect of  reducing  the
amount of any deficiency  claim to which Agent or any Lender might  otherwise be
entitled but for such bidding at any such sale.

         12.6 Limitation.  Notwithstanding any provision herein contained to the
              ----------
contrary, each Borrower's liability under this Section 12 (which liability is in
any event in  addition to amounts for which such  Borrower is  primarily  liable
under  Section  1) shall be limited to an amount not to exceed as of any date of
determination the greater of:

                  (a) the net amount of all Loans advanced to any other Borrower
under this Agreement and then re-loaned or otherwise  transferred to, or for the
benefit of, such Borrower; and

                  (b) the amount  which  could be  claimed by Agent and  Lenders
from such Borrower  under this Section 12 without  rendering such claim voidable
or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any
applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent  Conveyance
Act or similar  statute or common law after  taking  into  account,  among other
things,  such Borrower's  right of contribution  and  indemnification  from each
other Borrower under Section 12.7.

         12.7  Contribution  with  Respect to Guaranty  Obligations.  (a) To the
               ----------------------------------------------------
extent that any  Borrower  shall make a payment  under this Section 12 of all or
any of the  Obligations  (other than Loans made to that Borrower for which it is
primarily liable) (a "Guarantor  Payment") which,  taking into account all other
Guarantor Payments then previously or concurrently made by any


<PAGE>


other Borrower, exceeds the amount which such Borrower would otherwise have paid
if each Borrower had paid the aggregate  Obligations satisfied by such Guarantor
Payment in the same  proportion  that such  Borrower's  "Allocable  Amount"  (as
defined below) (as determined  immediately prior to such Guarantor Payment) bore
to the  aggregate  Allocable  Amounts  of each of the  Borrowers  as  determined
immediately  prior to the  making of such  Guarantor  Payment,  then,  following
indefeasible  payment in full in cash of the  Obligations and termination of the
Commitments,  such  Borrower  shall be  entitled  to  receive  contribution  and
indemnification payments from, and be reimbursed by, each other Borrower for the

                  III.  AGENT'S AND LENDERS' RIGHTS: LIMITATIONS ON AGENT'S AND
                        -------------------------------------------------------
   LENDERS' OBLIGATIONS.
   --------------------

                    A.    It is expressly agreed by Grantors that, anything 
   herein to the contrary notwithstanding, each Grantor shall remain liable 
   under each of its Contracts and each of its Licenses to observe and
   perform all the conditions and obligations to be observed and performed by 
   it thereunder.  Neither Agent nor any Lender shall have any obligation or 
   liability under any Contract or License by reason of or arising out of this 
   Security Agreement or the granting herein of a Lien thereon or the receipt 
   by Agent or any Lender of any payment relating to any Contract or License 
   pursuant hereto.  Neither Agent nor any Lender shall be required or obligated
   in any manner to perform or fulfill any of the obligations of any Grantor 
   under or pursuant to any Contract or License, or to make any payment, or to
   make any inquiry as to the nature or the sufficiency of any payment received
   by it or the sufficiency of any performance by any party under any Contract 
   or License, or to present or file any claims, or to take any action to 
   collect or enforce any performance or the payment of any amounts which may 
   have been assigned to it or to which it may be entitled at any time or times.

                     B.    Agent may at any time after an Event of Default
   shall have occurred and be continuing, without prior notice to any Grantor, 
   notify Account Debtors that the Accounts and related Collateral have been 
   assigned to Agent, and that payments shall be made directly to Agent.  Upon 
   the request of Agent, each Grantor shall so notify Account Debtors.

                     C.    Agent may at any time in Agent's own name or in the 
   name of any Grantor communicate with Account Debtors or parties to Contracts
   to verify with such Persons, to Agent's satisfaction, the existence, amount 
   and terms of any such Accounts and related Collateral.  If an Event of 
   Default shall have occurred and be continuing, each Grantor, at its own 
   expense, shall cause the independent certified public accountants then 
   engaged by such Grantor to prepare and deliver to Agent and each Lender at
   any time and from time to time promptly upon Agent's request the following 
   reports with respect to each Grantor: 1. a reconciliation of all Accounts;
   2. an aging of all Accounts; 3. trial balances; and 4. a test verification 
   of such Accounts as Agent may request.  Each Grantor, at its own expense, 
   shall deliver to Agent the results of each physical verification, if any, 
   which such Grantor may in its discretion have made, or caused any other 
   Person to have made on its behalf, of all or any portion of its Inventory.

                  IV.   REPRESENTATIONS AND WARRANTIES.  Each Grantor
                        ------------------------------
   represents and warrants that:

                       A.    Each Grantor is the sole owner of each item of the
   Collateral upon which it purports to grant a Lien hereunder, and has good and
   marketable title thereto free and clear of any and all Liens other than
   Permitted Encumbrances.

                       B.    No effective security agreement, financing 
   statement, equivalent security or Lien instrument or continuation statement 
   covering all or any part of the Collateral is on file or of record in any 
   public office, except such as may have been filed 1. by any Grantor in favor
   of Agent pursuant to this Security Agreement or the other Loan Documents, 
   and 2. in connection with any other Permitted Encumbrances.

                        C.    This Security Agreement is effective to create a
   valid and continuing Lien on and, upon the filing of the appropriate 
   financing statements listed on Schedule I hereto, a perfected Lien in favor 
                                  ----------
   of Agent, for itself and the benefit of Lenders, on the Collateral with 
   respect to which a Lien may be perfected by filing pursuant to the Code.  
   Such Lien is prior to all other Liens, except Permitted Encumbrances that 
   would be prior to Liens in favor of Agent for the benefit of Agent and 
   Lenders as a matter of law, and is enforceable as such as against any and all
   creditors of and purchasers from any Grantor (other than purchasers of 
   Inventory in the ordinary course of business).  All action by any Grantor 
   necessary or desirable to protect and perfect such Lien on each item of the 
   Collateral has been duly taken.

                        D.    Each Grantor's chief executive office, principal 
   place of business, corporate offices, all warehouses and premises where 
   Collateral is stored or located, and the locations of all of its books and 
   records concerning the Collateral are set forth on Schedule II hereto.
                                                      -----------

                        E.    With respect to the Accounts, except as 
   specifically disclosed in the most recent Collateral Report delivered to 
   Agent 1. they represent bona fide sales of Inventory or rendering of services
   to Account Debtors in the ordinary course of each Grantor's business and are
   not evidenced by a judgment, Instrument or Chattel Paper; 2. there are no 
   setoffs,claims or disputes existing or asserted with respect thereto and no
   Grantor has made any agreement with any Account Debtor for any extension of 
   time for the payment thereof, any compromise or settlement for less than the
   full amount thereof, any release of any Account Debtor from liability there-
   for, or any deduction therefrom except a discount or allowance allowed by
   such Grantorin the ordinary course of its business for prompt payment and 
   disclosed to Agent; 3. to each Grantor's knowledge, there are no facts,
   events or occurrences which in any way impair the validity or enforceability
   thereof or could reasonably be expected to reduce the amount payable there-
   under as shown on any Grantor's books and records and any invoices, state-
   ments and Collateral Reports delivered to Agent and Lenders with respect 
   thereto; 4. no Grantor has received any notice of proceedings or actions
   which are threatened or pending against any Account Debtor which might 
   result in any adverse change in such Account Debtor's financial condition;
   and 5. no Grantor has knowledge that any Account Debtor is unable generally
   to pay its debts as they become due. Further with respect to the Accounts 
   (x) the amounts shown on all invoices, statements and Collateral Reports 
   which may be delivered to the Agent with respect thereto are actually and
   absolutely owing to such Grantor as indicated thereon and are not in any way
   contingent; (y) no payments have been or shall be made thereon except
   payments immediately delivered to the applicable Borrower Accounts or the 
   Agent as required pursuant to the terms of Annex C to the Credit Agreement; 
   and (z) to each Grantor's knowledge, all Account Debtors have the capacity to
   contract.

                        F.    With respect to any Inventory scheduled or listed
   on the most recent Collateral Report delivered to Agent pursuant to the terms

   This Security Agreement is effective to create a valid and continuing Lien
   on and, upon filing of the Copyright Security Agreements with the United 
   States Copyright Office and filing of the Patent Security Agreements and the
   Trademark Security Agreements with the United State Patent and Trademark
   Office, perfected Liens in favor of Agent on each Grantor's Patents,
   Trademarks and Copyrights and such perfected Liens are enforceable as such 
   as against any and all creditors of and purchasers from any Grantor.  Upon 
   filing of the Copyright Security Agreements with the United States Copyright
   Office and filing of the Patent Security Agreements and the Trademark 
   Security Agreements with the United State Patent and Trademark Office and
   the filing of appropriate financing statements listed on Schedule I hereto, 
                                                            ----------
   all action necessary or desirable to protect and perfect Agent's Lien on 
   each Grantor's Patents, Trademarks or Copyrights shall have been duly taken.

                  V.    COVENANTS.  Each Grantor covenants and agrees with
                        ---------
   Agent, for the benefit of Agent and Lenders, that from and after the date of
   this Security Agreement and until the Termination Date:

                        A.    Further Assurances.  At any time and from time to
                              ------------------
   time, upon the written request of Agent and at the sole expense of Grantors,
   each Grantor shall promptly and duly execute and deliver any and all such
   further instruments and documents and take such further actions as Agent may
   deem desirable to obtain the full benefits of this Security Agreement and of
   the rights and powers herein granted, including 1. using its best efforts to
   secure all consents and approvals necessary or appropriate for the assignment
  to or for the benefit of Agent of any License or Contract held by such Grantor
   or in which such Grantor has any rights required to be assigned hereunder and
   not heretofore assigned, 2. filing any financing or continuation statements
   under the Code with respect to the Liens granted hereunder or under any other
   Document, 3. transferring Collateral to Agent's possession (for the
   benefit of Agent and Lenders) if such Collateral consists of Chattel Paper,
   Instruments or if a Lien on such Collateral can be perfected only by
   possession, or if requested by Agent, and 4. obtaining, or using its best
   efforts to obtain, waivers of Liens, if any exist, from landlords and
   mortgagees in accordance with the Credit Agreement.  Each Grantor also hereby
   authorizes Agent, for the benefit of Agent and Lenders, to file any such
   financing or continuation statements without the signature of such Grantor to
   the extent permitted by applicable law.  If any amount payable under or in
   connection with any of the Collateral is or shall become evidenced by any
   Instrument, such Instrument, other than checks and notes received in the
   ordinary course of business, shall be duly endorsed in a manner satisfactory
   to Agent immediately upon such Grantor's receipt thereof.

                        B.    Maintenance of Records.  Grantors shall keep and
                              ----------------------
   maintain, at their own cost and expense, satisfactory and complete records of
   the Collateral, including a record of any and all payments received and any
   and all credits granted with respect to the Collateral and all other dealings
   with the Collateral.  Grantors shall mark their books and records pertaining
   to the Collateral to evidence this Security Agreement and the Liens granted
   hereby.

                        C.    Covenants Regarding Patent, Trademark and
                              -----------------------------------------
            Copyright Collateral.
            --------------------

                             1.    Grantors shall notify Agent immediately if 
   they know or have reason to know that any application or registration 
   relating to any Patent, Trademark or Copyright (now or hereafter existing)
   may become abandoned or dedicated, or of any adverse determination or
   development (including the institution of, or any such determination or 
   development in, any proceeding in the United States Patent and Trademark
   Office, the United States Copyright Office or any court) regarding any 
   Grantor's ownership of any Patent, Trademark or Copyright, its right to 
   register the same, or to keep and maintain the same.

                              2.    In no event shall any Grantor, either 
   itself or through any agent, employee, licensee or designee, file an 
   application for the registration of any Patent, Trademark or Copyright 
   with the United States Patent and Trademark Office, the United States 
   Copyright Office or any similar office or agency without giving Agent prior
   written notice thereof, and, upon request of Agent, Grantor shall execute and
   deliver any and all Patent Security Agreements, Copyright Security Agreements
   or Trademark Security Agreements as Agent may request to evidence Agent's
   Lien on such Patent, Trademark or Copyright, and the General Intangibles of
   such Grantor relating thereto or represented thereby.

                              3.    Grantors shall take all actions necessary
   or requested by Agent to maintain and pursue each application, to obtain the
   relevant registration and to maintain the registration of each of the 
   Patents, Trademarks and Copyrights (now or hereafter existing), including 
   the filing of applications for renewal, affidavits of use, affidavits of 
   noncontestability and opposition and interference and cancellation 
   proceedings,[unless the applicable Grantor shall determine that such Patent,
   Trademark or Copyright is not material to the conduct of its business].

                              4.    In the event that any of the Patent, 
   Trademark or Copyright Collateral is infringed upon, or misappropriated or 
   diluted by a third party, such Grantor shall notify Agent promptly after 
   such Grantor learns thereof.  Such Grantor shall, unless such Grantor shall 
   reasonably determine that such Patent, Trademark or Copyright Collateral is
   in no way material to the conduct of its business or operations, promptly
   sue for infringement, misappropriation or dilution and to recover any and all
   damages for such infringement, misappropriation or dilution, and shall take 
   such other actions as Agent shall deem appropriate under the circumstances 
   to protect  such Patent, Trademark or Copyright Collateral.

                        D.    Indemnification.  In any suit, proceeding or
                              ---------------
  action brought by Agent or any Lender relating to any Account or any other
  Collateral for any sum owing thereunder or to enforce any provision of any
  Account or any other Collateral each Grantor will save, indemnify and keep
  Agent and Lenders harmless from and against all expense (including reasonable
  attorneys' fees and expenses), loss or damage suffered by reason of any
  defense, setoff, counterclaim, recoupment or reduction of liability whatsoever
  of the obligor thereunder, arising out of a breach by any Grantor of any
  obligation thereunder or arising out of any other agreement, indebtedness or
  liability at any time owing to, or in favor of, such obligor or its successors
  from such Grantor, except in the case of Agent or any Lender, to the extent
  such expense, loss, or damage is attributable solely to the gross negligence
  or willful misconduct of Agent or such Lender as finally determined by a court
  of competent jurisdiction.  All such obligations of Grantors shall be and
  remain enforceable against and only against Grantors and shall not be
  enforceable against Agent or any Lender.

                        E.    Compliance with Terms of Accounts, etc.  In all
                              ---------------------------------------
  material respects, each Grantor will perform and comply with all obligations
  in respect of its Accounts and other Collateral and all other agreements to
  which it is a party or by which it is bound relating to the Collateral.
                        F.    Limitation on Liens on Collateral.  No Grantor
                             ---------------------------------
  will create, permit or suffer to exist, and each Grantor will defend the
  Collateral against, and take such other action as is necessary to remove, any
  Lien on the Collateral except Permitted Encumbrances, and will defend the
  right, title and interest of Agent and Lenders in and to any of such Grantor's
  rights under the Collateral against the claims and demands of all Persons
  whomsoever.

                        G.    Limitations on Disposition.  No Grantor will sell,
                              --------------------------
  lease, transfer or otherwise dispose of any of the Collateral, or attempt or
  contract to do so except as permitted by the Credit Agreement.

                        H.    Further Identification of Collateral.  Grantors
                              ------------------------------------
  will, if so requested by Agent, furnish to Agent, as often as Agent requests,
  statements and schedules further identifying and describing the Collateral and
  such other reports in connection with the Collateral as Agent may reasonably
  request, all in such detail as Agent may specify.

                        I.    Notices.  Grantors will advise Agent promptly, in
                              -------
  reasonable detail, 1. of any Lien (other than Permitted Encumbrances) or claim
  made or asserted against any of the Collateral, and 2. of the occurrence of
  any other event which would have a material adverse effect on the aggregate
  value of the Collateral or on the Liens created hereunder or under any other
  Loan Document.

                  VI.   AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT.
                        ---------------------------------------
                       On the Closing Date each Grantor shall execute and 
   deliver to Agent a power of attorney (the "Power of Attorney") substantially
                                              -----------------
   in the form attached hereto as Exhibit A.  The power of attorney granted
   pursuant to the Power of Attorney is a power coupled with an interest and
   shall be irrevocable until the Termination Date.  The powers conferred on 
   Agent, for the benefit of Agent and Lenders, under the Power of Attorney
   are solely to protect Agent's interests (for the benefit of Agent and 
   Lenders) in the Collateral and shall not impose any duty upon Agent or 
   any Lender to exercise any such powers.  Agent agrees that A. it shall 
   not exercise any power or authority granted under the Power of Attorney 
   unless an Event of Default has occurred and is continuing, and B. Agent 
   shall account for any moneys received by Agent in respect of any 
   foreclosure on or disposition of Collateral pursuant to the Power of 
   Attorney provided that none of Agent or any Lender shall have any duty as 
   to any Collateral, and Agent and Lenders shall be accountable only for
   amounts that they actually receive as a result of the exercise of such 
   powers.  NONE OF AGENT, LENDERS OR THEIR RESPECTIVE AFFILIATES, OFFICERS, 
   DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES SHALL BE RESPONSIBLE TO 
   ANY GRANTOR FOR ANY ACT OR FAILURE TO ACT UNDER ANY POWER OF ATTORNEY OR 
   OTHERWISE, EXCEPT IN RESPECT OF DAMAGES ATTRIBUTABLE SOLELY TO THEIR OWN 
   GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AS FINALLY DETERMINED BY A
   COURT OF COMPETENT JURISDICTION, NOR FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR
   CONSEQUENTIAL DAMAGES.

                  VII.  REMEDIES: RIGHTS UPON DEFAULT.
                        -----------------------------
                      A.   In addition to all other rights and remedies granted
   to it under this Security Agreement, the Credit Agreement, the other Loan 
   Documents and under any other instrument or agreement securing, evidencing
   or relating to any of the Obligations, if any Event of Default shall have 
   occurred and be continuing, Agent may exercise all rights and remedies of 
   a secured party under the Code.  Without limiting the generality of the
   foregoing, each Grantor expressly agrees that in any such event Agent, 
   without demand of performance or other demand, advertisement or notice of
   any kind (except the notice specified below of time and place of public or 
   private sale) to or upon such Grantor or any other Person (all and each of
   which demands, advertisements and notices are hereby expressly waived to
   the maximum extent permitted by the Code and other applicable law), may 
   forthwith enter upon the premises of such Grantor where any Collateral 
   is located through self-help, without judicial process, without first
   obtaining a final judgment or giving such Grantor or any other Person notice
   and opportunity for a hearing on Agent's claim or action and may collect, 
   receive, assemble, process, appropriate and realize upon the Collateral, or
   any part thereof, and may forthwith sell, lease, assign, give an option or 
   options to purchase, or sell or otherwise dispose of and deliver said 
   Collateral (or contract to do so), or any part thereof, in one or more 
   parcels at a public or private sale or sales, at any exchange at such prices
   as it may deem acceptable, for cash or on credit or for future delivery 
   without assumption of any credit risk.  Agent or any Lender shall have 
   the right upon any such public sale or sales and, to the extent permitted by
   law, upon any such private sale or sales, to purchase for the benefit of 
   Agent and Lenders, the whole or any part of said Collateral so sold, free 
   of any right or equity of redemption, which equity of redemption each Grantor
   hereby releases.  Such sales may be adjourned and continued from time to
   time with or without notice.  Agent shall have the right to conduct such 
   sales on any Grantor's premises or elsewhere and shall have the right to
   use any Grantor's premises without charge for such time or times as Agent
   deems necessary or advisable.

                Each Grantor further agrees, at Agent's request, to assemble the
   Collateral and make it available to Agent at places which Agent shall select,
   whether at such Grantor's premises or elsewhere.  Until Agent is able to
   effect a sale, lease, or other disposition of Collateral, Agent shall have 
   the right to hold or use Collateral, or any part thereof, to the extent that
   it deems appropriate for the purpose of preserving Collateral or its value 
   or for any other purpose deemed appropriate by Agent.  Agent shall have no 
   obligation to any Grantor to maintain or preserve the rights of such Grantor
   as against third parties with respect to Collateral while Collateral is in 
   the possession of Agent.  Agent may, if it so elects, seek the appointment 
   of a receiver or keeper to take possession of Collateral and to enforce any
   of Agent's remedies (for the benefit of Agent and Lenders), with respect to 
   such appointment without prior notice or hearing as to such appointment.  
   Agent shall apply the net proceeds of any such collection, recovery, receipt,
   appropriation, realization or sale to the Obligations as provided in the 
   Credit Agreement, and only after so paying over such net proceeds, and 
   after the payment by  Agent of any other amount required by any provision of
   law, need Agent account for the surplus, if any, to any Grantor.  To the 
   maximum extent permitted by applicable law, each Grantor waives all claims,
   damages, and demands against Agent or any Lender arising out of the 
   repossession, retention or sale of the Collateral except such as arise solely
   out of the gross negligence or willful misconduct of Agent or such Lender as
   finally determined by a court of competent jurisdiction.  Each Grantor agrees
   that ten (10) days prior notice by Agent of the time and place of any public
   sale or of the time after which a private sale may take place is reasonable 
   notification of such matters.  Grantors shall remain liable for any 
   deficiency if the proceeds of any sale or disposition of the Collateral are 
   insufficient to pay all Obligations, including any attorneys' fees and other
   expenses incurred by Agent or any Lender to collect such deficiency.

                        B.    Except as otherwise specifically provided herein,
   each Grantor hereby waives presentment, demand, protest or any notice (to 
   the maximum extent permitted by applicable law) of any kind in connection 
   with this Security Agreement or any Collateral.

                  VIII. GRANT OF LICENSE TO USE INTELLECTUAL PROPERTY
                        ---------------------------------------------
   COLLATERAL.  For the purpose of enabling Agent to exercise rights and   
   ----------
   remedies under Section 7 hereof (including, without limiting the terms of
                  ---------
   Section 7 hereof, in order to take possession of, hold, preserve, process, 
   ---------
   assemble, prepare for sale, market for sale, sell or otherwise dispose of 
   Collateral) at such time as Agent shall be lawfully entitled to exercise such
   rights and remedies, each Grantor hereby grants to Agent, for the benefit of
   Agent and Lenders, an irrevocable, non-exclusive license (exercisable
   without payment of royalty or other compensation to such Grantor) to use, 
   license or sublicense any Intellectual Property now owned or hereafter 
   acquired by such Grantor, and wherever the same may be located, and including
   in such license access to all media in which any of the licensed items may 
   be recorded or stored and to all computer software and programs used for the
   compilation or printout thereof.

                  IX.   LIMITATION ON AGENT'S AND LENDERS' DUTY IN RESPECT OF 
                        ----------------------------------------------------
   COLLATERAL. Agent and each Lender shall use reasonable care with respect to 
   ----------
   the Collateral in its possession or under its control.  Neither Agent nor any
   Lender shall have any other duty as to any Collateral in its possession or
   control or in the possession or control of any agent or nominee of Agent or
   such Lender, or any income thereon or as to the preservation of rights 
   against prior parties or any other rights pertaining thereto.

                  X.    REINSTATEMENT.  This Security Agreement shall remain 
                        -------------
   in full force and effect and continue to be effective should any petition 
   be filed by or against any Grantor for liquidation or reorganization, should
   any Grantor become insolvent or make an assignment for the benefit of any 
   creditor or creditors or should a receiver or trustee be appointed for all 
   or any significant part of any Grantor's assets, and shall continue to be 
   effective or be reinstated, as the case may be, if at any time payment and
   performance of the Obligations, or any part thereof, is, pursuant to 
   applicable law, rescinded or reduced in amount, or must otherwise be
   restored or returned by any obligee of the Obligations, whether as a 
   "voidable preference," "fraudulent conveyance," or otherwise, all as 
   though such payment or performance had not been made.  In the event that 
   any payment, or any part thereof, is rescinded, reduced, restored or 
   returned, the Obligations shall be reinstated and deemed reduced only by
   such amount paid and not so rescinded, reduced, restored or returned.

                  XI.   NOTICES.  Except as otherwise provided herein, whenever
                        -------
   it is provided herein that any notice, demand, request, consent, approval,
   declaration or other communication shall or may be given to or served upon
   any of the parties by any other party, or whenever any of the parties 
   desires to give and serve upon any other party any communication with 
   respect to this Security Agreement, each such notice, demand, request, 
   consent, approval, declaration or other communication shall be in writing
   and shall be given in the manner, and deemed received, as provided for in 
   the Credit Agreement.

                  XII.  SEVERABILITY.  Whenever possible, each provision of 
                        ------------
   this Security Agreement shall be interpreted in a manner as to be effective
   and valid under applicable law, but if any provision of this Security 
   Agreement shall be prohibited by or invalid under applicable law, such
   provision shall be ineffective to the extent of such prohibition or 
   invalidity without invalidating the remainder of such provision or the 
   remaining provisions of this Security Agreement.  This Security Agreement is
   to be read, construed and applied together with the Credit Agreement and the 
   other Loan Documents which, taken together, set forth the complete 
   understanding and agreement of Agent, Lenders and Grantors with respect to
   the matters referred to herein and therein.

                  XIII. NO WAIVER; CUMULATIVE REMEDIES.  Neither Agent nor
                        ------------------------------
   any Lender shall by any act, delay, omission or otherwise be deemed to have
   waived any of its rights or remedies hereunder, and no waiver shall be valid
   unless in writing, signed by Agent and then only to the extent therein set
   forth.  A waiver by Agent of any right or remedy hereunder on any one 
   occasion shall not be construed as a bar to any right or remedy which Agent
   would otherwise have had on any future occasion.  No failure to exercise nor
   any delay in exercising on the part of Agent or any Lender, any right, power
   or privilege hereunder, shall operate as a waiver thereof, nor shall any 
   single or partial exercise of any right, power or privilege hereunder 
   preclude any other or future exercise thereof or the exercise of any other 
   right, power or privilege.  The rights and remedies hereunder provided are 
   cumulative and may be exercised singly or concurrently, and are not 
   exclusive of any rights and remedies provided by law.  None of the terms or
   provisions of this Security Agreement may be waived, altered, modified or
   amended except by an instrument in writing, duly executed by Agent and
   Grantors.

                  XIV.  LIMITATION BY LAW.  All rights, remedies and powers
                        -----------------
   provided in this Security Agreement may be exercised only to the extent that
   the exercise thereof does not violate any applicable provision of law, and
   all the provisions of this Security Agreement are intended to be subject to
   all applicable mandatory provisions of law that may be controlling and to be
   limited to the extent necessary so that they shall not render this Security
   Agreement invalid, unenforceable, in whole or in part, or not entitled to be
   recorded, registered or filed under the provisions of any applicable law.

                  XV.   TERMINATION OF THIS SECURITY AGREEMENT.  Subject to
                        --------------------------------------
   Section 10 hereof, this Security Agreement shall terminate upon
   ----------
   the Termination Date.

                  XVI.  SUCCESSORS AND ASSIGNS.  This Security Agreement and
                        ----------------------
   all obligations of Grantors hereunder shall be binding upon the successors
   and assigns of each Grantor (including any debtor-in-possession on behalf
   of such Grantor) and shall, together with the rights and remedies of Agent,
   for the benefit of Agent and Lenders, hereunder, inure to the benefit of
   Agent and Lenders, all future holders of any instrument evidencing any of
   the Obligations and their respective successors and assigns.  No sales of
   participations, other sales, assignments, transfers or other dispositions of
   any agreement governing or instrument evidencing the Obligations or any
   portion thereof or interest therein shall in any manner affect the Lien
   granted to Agent, for the benefit of Agent and Lenders, hereunder. No 
   Grantor may assign, sell, hypothecate or otherwise transfer any interest in
   or obligation under this Security Agreement.

                  XVII. COUNTERPARTS.  This Security Agreement may be
                        ------------
   executed in any number of separate counterparts, each of which shall
   collectively and separately constitute one agreement.

                  XVIII.      GOVERNING LAW.  EXCEPT AS OTHERWISE EXPRESSLY
                              -------------
   PROVIDED IN ANY OF THE LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING ALL MATTERS
   OF CONSTRUCTION, VALIDITY AND PERFORMANCE, THIS SECURITY AGREEMENT AND THE
   OBLIGATIONS ARISING HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND 
   ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
   CONTRACTS MADE AND PERFORMED IN THAT STATE, AND ANY APPLICABLE LAWS OF THE 
   UNITED STATES OF AMERICA.  EACH GRANTOR HEREBY CONSENTS AND AGREES THAT THE 
   STATE OR FEDERAL COURTS LOCATED IN NEW YORK COUNTY, CITY OF NEW YORK, NEW 
   YORK, SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR
   DISPUTES BETWEEN GRANTORS, AGENT AND LENDERS PERTAINING TO THIS SECURITY 
   AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY MATTER ARISING OUT OF
   OR RELATING TO THIS SECURITY AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, 
   PROVIDED, THAT AGENT, LENDERS AND GRANTORS ACKNOWLEDGE THAT ANY APPEALS
   FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK
   COUNTY, CITY OF NEW YORK,  NEW YORK, AND, PROVIDED, FURTHER, NOTHING IN THIS
   AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE AGENT FROM BRINGING SUIT OR
   TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE 
   COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A 
   JUDGMENT OR OTHER COURT ORDER IN FAVOR OF AGENT.  EACH GRANTOR EXPRESSLY 
   SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT
   COMMENCED IN ANY SUCH COURT, AND EACH GRANTOR HEREBY WAIVES ANY OBJECTION 
   WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE 
   OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR
   EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT.  EACH GRANTOR 
   HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS
   ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, 
   COMPLAINTS AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL

   ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY 
   ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER SOUNDING
   IN CONTRACT, TORT, OR OTHERWISE, AMONG AGENT, LENDERS, AND GRANTORS ARISING

   LOAN DOCUMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO.

   hereto.

                        ----------------------
   participated jointly in the negotiation and drafting of this Security
   Agreement.  In the event an ambiguity or question of intent or interpretation

   specifically, the provisions of Section 18 and Section 19, with its counsel.
                                   ----------     ----------

                  XXIII.      BENEFIT OF LENDERS.  All Liens granted or
                              ------------------

<PAGE>


in and under such Contracts, Instruments and Chattel Paper have been assigned to
Agent, and, upon the occurrence of an Event of Default, may notify any such
Account Debtors, such parties to any Contracts of Grantor and such obligors that
payments shall be made directly to Agent. Upon the request of Agent, Grantor
shall so notify such Account Debtors, parties to Contracts and obligors in
respect of Instruments and Chattel Paper. Grantor acknowledges that any payments
on or other proceeds of Collateral received by Grantor from such Account
Debtors, whether before or after notification of this Security Interest to such
Account Debtors and whether before or after the occurrence of a Default or an
Event of Default, shall be received and held by Grantor in trust for Agent and
shall be turned over to Agent upon request.

3.3 VERIFICATION OF ACCOUNTS. Agent may at any time in Agent's own name or in
the name of Grantor communicate with Account Debtors, parties to Contracts,
obligors in respect of Instruments and obligors in respect of Chattel Paper to
verify with such Persons, to Agent's satisfaction, the existence, amount and
terms of any such Accounts, Contracts, Instruments or Chattel Paper. If an Event
of Default shall have occurred and be continuing, Grantor, at its own expense,
shall cause the independent chartered accountants then engaged by such Grantor
to prepare and deliver to Agent and each Lender at any time and from time to
time promptly upon Agent's request the following reports with respect to
Grantor: (i) a reconciliation of all Accounts; (ii) an aging of all Accounts;
(iii) trial balances; and (iv) a test verification of such Accounts as Agent may
request. Grantor, at its own expense, shall deliver to Agent the results of each
physical verification, if any, which Grantor may in its discretion have made, or
caused any other Person to have made on its behalf, of all or any portion of its
Inventory.

                  party or to which such property is subject; and

         (13)     Grantor has no interest in, or title to, any Patent, Trademark

                  hereto, with the Canadian Intellectual Property Office,

                  necessary or desirable to protect and perfect Agent's Lien on
                  Grantor's Patents, Trademarks or Copyrights shall have been
                  duly taken.

SECTION 5 -- COVENANTS OF THE DEBTOR

5.1 COVENANTS. So long as this Agreement remains in effect, Grantor covenants
and agrees with Agent and Lenders as follows:

(1) DEFENCE OF COLLATERAL. Grantor shall defend the Collateral against the
claims and demands of all other parties claiming the same or an interest
therein; shall take all reasonable action to keep the Collateral free from all
Liens, except for Permitted Encumbrances or those Liens hereafter approved in
writing by Agent, prior to their creation or assumption, and shall not sell,
exchange, transfer, assign, lease, license or otherwise dispose of Collateral or
any interest therein without the prior written consent of Agent; provided always
that, until default Grantor may, in the ordinary course of Grantor's business,
sell or lease Inventory and, subject to the

<PAGE>


Credit Agreement and the Canadian Blocked Account Agreement, use Money in the
Disbursement Account.

(2) NOTICE TO AGENT. Grantor shall notify Agent promptly of:

          (a)  any change in the information contained herein or in the

               Collateral,

          (b)  the details of any significant acquisition of Collateral,

          (c)  the details of any claims or litigation affecting Grantor or
               Collateral,

condition and repair and not use Collateral in violation of the provisions of
this Agreement or any other agreement relating to Collateral or any policy
insuring Collateral or any applicable statute, law, by-law, rule, regulation or
ordinance; shall keep all agreements, registrations and applications relating to
Intellectual Property constituting Collateral and such Intellectual Property
used by Grantor in its business in good standing and renew all agreements and
registrations as may be necessary or desirable to protect such Intellectual
Property, unless otherwise agreed in writing by Agent; and shall apply to

<PAGE>

register all existing and future Intellectual Property constituting Collateral
whenever it is commercially reasonable to do so.

(4) FURTHER ASSURANCES; PLEDGE OF INSTRUMENTS. At any time and from time to
time, upon the written request of Agent and at the sole expense of Grantor,
Grantor shall promptly and duly execute and deliver any all such further
instruments and documents (including deeds of hypothec with respect to
Collateral located in the Province of Quebec) and take such further actions as
Agent may reasonably deem desirable to obtain the full benefits of this
Agreement and the other Loan Documents to which Grantor is a party and of the
rights and powers herein and therein granted, including (i) filing any financing
or continuation statements (or the applicable equivalent) under applicable law
with respect to the Liens granted hereunder or under any other Loan Document to
which Grantor is a party, and (ii) transferring Collateral to Agent's possession
(for the benefit of Agent and Lenders) if such Collateral consists of Documents
of Title, Securities, Investment Property, Chattel Paper, Instruments or if a
Lien on such Collateral can be perfected only by possession, or if requested by
Agent, Grantor also hereby authorizes Agent, for the benefit of Agent and
Lenders, to file any such financing or continuation statements (or the
applicable equivalent) without the signature of Grantor to the extent permitted
by applicable law. If any amount payable under or in connection with any of the
Collateral is or shall become evidenced by any Instrument, such Instrument,
other than cheques and notes received in the ordinary course of business, shall
be duly endorsed in a manner satisfactory to Agent immediately upon Grantor's 
receipt thereof.

(5) TAXES. Grantor shall pay all taxes, rates, levies, assessments and other
charges of every nature which may be lawfully levied, assessed or imposed
against or in respect of Grantor or Collateral as and when the same become due
and payable.

(6) CONDUCT OF BUSINESS. Grantor shall carry on and conduct the business of
Grantor in a proper and efficient manner and so as to protect and preserve
Collateral and keep, in accordance with Canadian generally accepted accounting
principles, consistently applied, proper books of account for Grantor's business
as well as accurate and complete records concerning Collateral, and mark any and
all such records and Collateral at Agent's request so as to indicate Agent's
Security Interest.

(7) ADDITIONAL DOCUMENTS. Grantor shall deliver to Agent from time to time
promptly upon request:

     (a)  any Documents of Title, Instruments, Securities, Investment Property
          and Chattel Paper constituting, representing or relating to
          Collateral,

     (b)  all Records or other books of account, records, ledgers, reports,
          correspondence, schedules, documents, statements, lists and other
          writings relating to Collateral for the purpose of inspecting,

          and affairs as Agent may reasonably request.

(8) INDEMNIFICATION. In any suit, proceeding or action brought by Agent or any
Lender relating to any Account, Chattel Paper, Contract, Document of Title,
Intangible or Instrument for any sum owing thereunder or to enforce any
provision of any Account, Chattel Paper, Contract, Document of Title, Intangible
or Instrument, Grantor will save, indemnify and keep Agent and Lenders harmless
from and against all expense (including reasonable legal fees and expenses),
loss or damage suffered by reason of any defence, set-off, counterclaim,
recoupment, or reduction of liability whatsoever of the obligor thereunder,
arising out of a breach by Grantor of any obligation thereunder or arising out
of any other agreement, indebtedness or liability at any time owing to, or in
favour of, such obligor or its successors from Grantor, except in the case of
Agent or any Lender, to the extent such expense, loss, or damage is attributable
solely to the gross negligence or wilful misconduct of Agent or such Lender as
finally determined by a court of competent jurisdiction. All such obligations of
Grantor shall be and remain enforceable against and only against Grantor and
shall not be enforceable against Agent or any Lender.

(9) CHANGE OF CORPORATE NAME OR LOCATION. Grantor shall not (1) change its
corporate name, or (2) change its chief executive office, principal place of
business, domicile (within the meaning of Quebec Civil Code), corporate offices
or warehouses or locations at which Collateral is held or stored, or the
location of its records concerning the Collateral, in any case without at least
thirty (30) days' prior written notice to Agent and after Agent's written
acknowledgment that any action requested by Agent in connection therewith,
including to continue the perfection of any Liens in favour of Agent, on behalf
of Agent and Lenders, or in favour of Agent and Lenders, as appropriate, in any
Collateral, has been completed or taken and provided that any such new location
shall be in Canada or the United States of America.

(10)     INTELLECTUAL PROPERTY.

     (a)  Grantor shall notify Agent immediately if they know or have reason to
          know that any application or registration relating to any of Grantor's
          Patents, Trademarks or Copyrights (now or hereafter existing) may
          become abandoned or dedicated, or of any adverse determination or
          development (including the institution of, or any such determination
          or development in, any proceeding in the Canadian Intellectual
          Property Office or the United States Patent and Trademark Office or
          the United States Copyright Office or any court) regarding Grantor's
          ownership of any Patent, Trademark or Copyright, its rights to
          register the same, or to keep and maintain the same.

     (b)  In no event shall Grantor, either itself or through any agent,
          employee, licensee or designee, file an application for the
          registration of any Patent, Trademark or Copyright with the Canadian
          Intellectual Property Office or the United States Patent and Trademark
          Office or the United States Copyright Office or any similar office or
          agency without giving Agent prior written notice thereof, and, upon
          request of Agent, Grantor shall execute and deliver any and all

<PAGE>

          intellectual property security agreements, as Agent may request to
          evidence Agent's Lien on such Patent, Trademark or Copyright, and the
          General Intangibles and Intangibles of Grantor relating thereto or
          represented thereby.

     (c)  Grantor shall take all actions necessary or requested by Agent to
          maintain and pursue each application, to obtain the relevant
          registration and to maintain the registration of each of Grantor's
          Patents, Trademarks and Copyrights (now or hereafter existing),
          including the filing of applications for renewal, affidavits or
          declarations of use, affidavits of non-contestability and opposition
          and interference and cancellation proceedings, unless the Grantor
          shall determine that such Patent, Trademark or Copyright is not
          material to the conduct of its business.

     (d)  In the event that any of Grantor's Patent, Trademark or Copyright
          Collateral is infringed upon, or misappropriated or diluted by a third
          party, Grantor shall notify Agent promptly after Grantor learns
          thereof. Grantor shall, unless Grantor shall
          reasonably determine that such Patent, Trademark or Copyright
          Collateral is in no way material to the conduct of its
          business or operations, promptly sue for infringement,
          misappropriation or dilution and to recover any and all
          damages for such infringement, misappropriation or dilution,
          and shall take such other actions as Agent shall deem
          appropriate under the circumstances to protect such Patent,
          Trademark or Copyright Collateral.

SECTION 6 -- USE AND VERIFICATION OF COLLATERAL

6.1 USE AND VERIFICATION OF COLLATERAL. Subject to compliance with Grantor's
covenants contained herein and Section 7.1 hereof, Grantor may, until the
occurrence of a Default or an Event of Default, possess, operate, collect, use
and enjoy and deal with Collateral in the ordinary course of Grantor's business
in any manner not inconsistent with the provisions hereof and the other Loan
Documents; provided always that Agent shall have the right at any time and from
time to time to verify the existence and state of the Collateral in any manner
Agent may consider appropriate and Grantor agrees to furnish all assistance and
information and to perform all such acts as Agent may reasonably request in
connection therewith and for such purpose to grant to Agent or its agents access
to all places where Collateral may be located and to all premises occupied by
Grantor, as contemplated by the Credit Agreement.

SECTION 7 -- SECURITIES

7.1 SECURITIES. If Collateral at any time includes Securities, Grantor
authorizes Agent to transfer the same or any part thereof into its own name or
that of its nominee(s) so that Agent or its nominee(s) may appear of record as
the sole owner thereof. Until the occurrence of a Default or an Event of
Default, Agent shall deliver promptly to Grantor all notices or other
communications received by it or its nominee(s) as such registered owner and,
upon demand and receipt of payment of any necessary expenses thereof, shall
issue to Grantor or its order a proxy to vote and take all action with respect
to such Securities. After the occurrence of a Default or an Event of Default,
Grantor waives all rights to receive any notices or communications received by
Agent or its nominee(s) as such registered owner and agrees that no proxy issued

<PAGE>

by Agent to Grantor or its order as aforesaid shall thereafter be effective.

SECTION 8 -- REMEDIES

8.1 APPOINTMENT OF RECEIVER. Upon the occurrence of and during the continuance
of any Default or Event of Default, Agent may appoint or reappoint by instrument
in writing, any Person or Persons, whether an officer or officers or an employee
or employees of Agent or not, to be a receiver or receivers (hereinafter called
a "RECEIVER", which term when used herein shall include a receiver and manager)
of Collateral (including any interest, income or profits therefrom) and may
remove any Receiver so appointed and appoint another in his/her/its stead. Any
such Receiver shall, so far as concerns responsibility for his/her/its acts, be
deemed the agent of Grantor and not Agent or any of Lenders, and neither Agent
nor any of Lenders shall be in any way responsible for any misconduct, 
negligence or non-feasance on the part of any such Receiver, his/her/its 
servants, agents or employees. Subject to the provisions of the instrument 
appointing him/her/it, any such Receiver shall have power to take possession of
Collateral, to preserve Collateral or its value, to carry on or concur in 
carrying on all or any part of the business of Grantor and to sell, lease, 
license or otherwise dispose of or concur in selling, leasing, licensing or
otherwise disposing of Collateral. To facilitate the foregoing powers, any 
such Receiver may, to the exclusion of all others, including Grantor, enter 
upon, use and occupy all premises owned or occupied by Grantor wherein 
Collateral may be situate, maintain Collateral upon such premises, borrow money
on a secured or unsecured basis and use Collateral directly in carrying on 
Grantor's business or as security for loans or advances to enable the Receiver
to carry on Grantor's business or otherwise, as such Receiver shall, in its 
discretion, determine. Except as may be otherwise directed by Agent, all Money
received from time to time by such Receiver in carrying out his/her/its 
appointment shall be received in trust for and paid over to Agent. Every such 
Receiver may, in the discretion of Agent, be vested with all or any of the 
rights and powers of Agent.

8.2 EXERCISE OF RIGHTS BY AGENT. Upon and during the continuance of a Default or
Event of Default, Agent may, either directly or through its agents or nominees,
exercise any or all of the powers and rights given to a Receiver by virtue of
Section 8.1.

8.3 TAKING POSSESSION OF COLLATERAL. Agent may take possession of, collect,
demand, sue on, enforce, recover and receive Collateral and give valid and
binding receipts and discharges therefor and in respect thereof and, upon the
occurrence of a Default or an Event of Default, Agent may sell, license, lease
or otherwise dispose of Collateral in such manner, at such time or times and
place or places, for such consideration and upon such terms and conditions as to
Agent may seem reasonable.

8.4 RIGHTS AND REMEDIES UNDER PPSA. In addition to those rights granted herein
and in any other agreement now or hereafter in effect between Grantor and Agent
and any Lender and in addition to any other rights Agent or Lenders may have at
law or in equity, Agent shall have, both before and after the occurrence of a
Default or an Event of Default, all rights and remedies of a secured party under
the PPSA. However, Agent shall not be liable or accountable for any failure to
exercise its remedies, take possession of, collect, enforce, realize, sell,

<PAGE>

lease, license or otherwise dispose of Collateral or to institute any
proceedings for such purposes. Furthermore, Agent shall have no obligation to
take any steps to preserve rights against prior parties to any Instrument or
Chattel Paper whether Collateral or proceeds and whether or not in Agent's
possession and shall not be liable or accountable for failure to do so.

8.5 COOPERATION OF GRANTOR WITH RESPECT TO TAKING POSSESSION. Grantor
acknowledges that Agent or any Receiver appointed by it may take possession of
Collateral wherever it may be located and by any method permitted by law and
Grantor agrees upon request from Agent or any such Receiver to assemble and
deliver possession of Collateral at such place or places as directed.

8.6 COSTS. Grantor agrees to be liable for and to pay all costs, charges and
expenses reasonably incurred by Agent, any Lender or any Receiver appointed by
it, whether directly or for services rendered (including reasonable solicitors
and auditors costs and other legal expenses and Receiver remuneration), in
operating Grantor's accounts, in preparing or enforcing this Agreement, taking
and maintaining custody of, preserving, repairing, processing, preparing for
disposition and disposing of Collateral and in enforcing or collecting
indebtedness and all such costs, charges and expenses, together with any amounts
owing as a result of any borrowing by Agent, any Lender or any Receiver
appointed by it, as permitted hereby, shall be a first charge on the proceeds of
realization, collection or disposition of Collateral and shall be secured
hereby.

8.7 NOTICE OF SALE. The Agent will give Grantor such notice, if any, of the
date, time and place of any public sale or of the date after which any private
disposition of Collateral is to be made as may be required by the PPSA.

8.8 GRANT OF LICENCE TO USE INTELLECTUAL PROPERTY COLLATERAL. For the purpose of
enabling Agent to exercise rights and remedies under Section 8 hereof
(including, without limiting the terms of Section 8 hereof, in order to take
possession of, hold, preserve, process, assemble, prepare for sale, market for
sale, sell or otherwise dispose of Collateral) at such time as Agent shall be
lawfully entitled to exercise such rights and remedies, Grantor hereby grants to
Agent, for the benefit of Agent and Lenders, an irrevocable, non-exclusive
licence (exercisable without payment of royalty or other compensation to such
Grantor) to use, license or sublicense any Intellectual Property now owned or
hereafter acquired by Grantor, and wherever the same may be located, and
including in such license access to all media in which any of the licensed items
may be recorded or stored and to all computer software and programs used for the
compilation or printout thereof.

SECTION 9 -- MISCELLANEOUS

9.1 PERFORMANCE BY AGENT. Upon Grantor's failure to perform any of its duties
hereunder, Agent may, but shall not be obligated to, perform any or all of such
duties, and Grantor shall pay to Agent, forthwith upon written demand therefor,
an amount equal to the expense incurred by Agent in so doing plus interest
thereon from the date such expense is incurred until it is paid at an annual
rate of interest equal to the sum of the Index Rate plus the Applicable Revolver
Index Margin plus 2% per annum, as determined by Agent on the basis of a three
hundred and sixty (360) day year, in each case for the actual number of days
occurring in the period for which such interest is payable. The Index Rate shall

<PAGE>

be determined each day based upon the Index Rate as in effect each day. For the
purposes of the Interest Act (Canada), such rate of interest shall be equivalent
to a rate based on a calendar year equal to such rate of interest multiplied by
the actual number of days in the calendar year of calculation and divided by
360.

9.2 EXTENSIONS, ETC. Agent may grant extensions of time and other indulgences,
take and give up security, accept compositions, compound, compromise, settle,
grant releases and discharges and otherwise deal with Grantor, debtors of
Grantor, any other Credit Party, sureties and others and with Collateral and 
other security as Agent may see fit without prejudice to the liability of 
Grantor or Agent's right to hold and realize the Security Interest. Furthermore,
Agent may demand, collect and sue on Collateral in either Grantor's or Agent's
name, at Agent's option, and may endorse Grantor's name on any and all cheques,
commercial paper, and any other Instruments pertaining to or constituting 
Collateral.

9.3 NO WAIVER. No delay or omission by Agent in exercising any right or remedy
hereunder or with respect to any of the Obligations 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. Furthermore, Agent may remedy any default by Grantor
hereunder or with respect to any Obligations in any reasonable manner without
waiving the default remedied and without waiving any other prior or subsequent
default by Grantor. All rights and remedies of Agent granted or recognized
herein are cumulative and may be exercised at any time and from time to time
independently or in combination.

Security Interest granted hereby:

         (1)      shall extend to "Collateral" (as that term is herein defined)
                  owned by each of the amalgamating companies and the
                  amalgamated company at the time of amalgamation and to any

and shall be irrevocable until the Termination Date. The powers conferred on 
Agent, for the benefit of Agent and Lenders, under the Power of Attorney are 
solely to protect Agent's interests (for the benefit of Agent and Lenders) in
the Collateral and shall not impose any duty upon Agent or any Lender to 
exercise any such powers. Agent agrees that (a) it shall not exercise any power
of attorney or authority granted under the Power of Attorney unless an Event of

Collateral and, following an Event of Default, to realize upon the Security
Interest.

be governed by and construed in accordance with the laws of the province of
Ontario, as the same may from time to time be in effect, including, where

                                    GUARANTY



         This GUARANTY (this "Guaranty"),  dated as of May 7, 1999, by and among
the  Guarantors  identified  as such  on the  signature  page  hereof  (each,  a
"Guarantor"  and  collectively,  "Guarantors"),  and  GENERAL  ELECTRIC  CAPITAL
CORPORATION,  a New  York  corporation,  individually  and  as  agent  (in  such
capacity, "Agent") for itself and the lenders from time to time signatory to the
Credit Agreement hereinafter defined ("Lenders").

                              W I T N E S S E T H:
                              -------------------

         WHEREAS, pursuant to that certain Credit Agreement dated as of the date
hereof by and among  Guarantors,  the Persons named  therein as Credit  Parties,
Agent and the Persons  signatory  thereto  from time to time as Lenders (as from
time to time amended, restated,  supplemented or otherwise modified, the "Credit
Agreement")  Lenders  have  agreed to make Loans to, and incur  Letter of Credit
Obligations for the benefit of, Borrowers.

         WHEREAS, Guarantors are affiliates of each of the Borrowers and as such
will derive direct and indirect  economic  benefits from the making of the Loans
and other financial  accommodations provided to Borrowers pursuant to the Credit
Agreement; and

         WHEREAS,  in order to induce Agent and Lenders to enter into the Credit
Agreement and other Loan  Documents and to induce  Lenders to make the Loans and
to incur Letter of Credit  Obligations as provided for in the Credit  Agreement,
Guarantors have agreed to guarantee payment of the Obligations;

         NOW,  THEREFORE,  in  consideration  of the premises and the  covenants
hereinafter  contained,  and to induce  Lenders to  provide  the Loans and other
financial accommodations under the Credit Agreement, it is agreed as follows:

1.       DEFINITIONS.
         -----------

         Capitalized  terms used herein shall have the meanings assigned to them
in the Credit Agreement, unless otherwise defined herein.

         References to this "Guaranty"  shall mean this Guaranty,  including all
amendments,   modifications  and  supplements  and  any  annexes,  exhibits  and
schedules to any of the foregoing,  and shall refer to this Guaranty as the same
may be in effect at the time such reference becomes operative.

2.       THE GUARANTY.
         ------------

         2.1 Guaranty of  Guaranteed  Obligations  of Borrower.  Each  Guarantor
             -------------------------------------------------
hereby  jointly and severally  unconditionally  guarantees to Agent and Lenders,
and their respective successors,  endorsees, transferees and assigns, the prompt
payment  (whether  at  stated  maturity,   by  acceleration  or  otherwise)  and
performance  of  the  Obligations  of  Borrowers  (hereinafter  the  "Guaranteed
Obligations").  Guarantors agree that this Guaranty is a guaranty of payment and
performance  and not of  collection,  and  that  their  obligations  under  this
Guaranty  shall be primary,  absolute and  unconditional,  irrespective  of, and
unaffected by:




<PAGE>



                  (a) the genuineness,  validity, regularity,  enforceability or
any future amendment of, or change in this Guaranty,  any other Loan Document or
any other  agreement,  document or  instrument  to which any Credit Party and/or
Guarantors are or may become a party;

                  (b) the absence of any action to enforce this  Guaranty or any
other  Loan  Document  or the waiver or consent  by Agent  and/or  Lenders  with
respect to any of the provisions thereof;

                  (c) the  existence,  value or  condition  of,  or  failure  to
perfect its Lien against,  any Collateral for the Guaranteed  Obligations or any
action,  or the absence of any action,  by Agent in respect thereof  (including,
without limitation, the release of any such security); or

                  (d)      the insolvency of any Credit Party; or

                  (e) any other action or  circumstances  which might  otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,

         it being  agreed by each  Guarantor  that its  obligations  under  this
Guaranty  shall not be discharged  until the  Termination  Date.  Each Guarantor
shall be regarded,  and shall be in the same position,  as principal debtor with
respect to the Guaranteed Obligations.  Each Guarantor agrees that any notice or
directive  given at any time to Agent which is  inconsistent  with the waiver in
the immediately  preceding sentence shall be null and void and may be ignored by
Agent and  Lenders,  and,  in  addition,  may not be  pleaded or  introduced  as
evidence in any  litigation  relating to this  Guaranty for the reason that such
pleading or  introduction  would be at variance  with the written  terms of this
Guaranty,  unless  Agent and  Lenders  have  specifically  agreed  otherwise  in
writing. It is agreed among each Guarantor, Agent and Lenders that the foregoing
waivers are of the essence of the transaction contemplated by the Loan Documents
and that,  but for this  Guaranty  and such  waivers,  Agent and  Lenders  would
decline to enter into the Credit Agreement.

         2.2  Demand  by Agent  or  Lenders.  In  addition  to the  terms of the
              -----------------------------
Guaranty  set  forth in  Section  2.1  hereof,  and in no  manner  imposing  any
limitation on such terms, it is expressly understood and agreed that, if, at any
time, the outstanding  principal amount of the Guaranteed  Obligations under the
Credit  Agreement  (including  all accrued  interest  thereon) is declared to be
immediately due and payable,  then Guarantors shall,  without demand, pay to the
holders  of  the  Guaranteed   Obligations  the  entire  outstanding  Guaranteed
Obligations due and owing to such holders.  Payment by Guarantors  shall be made
to Agent in  immediately  available  Federal  funds to an account  designated by
Agent or at the address set forth herein for the giving of notice to Agent or at
any other  address  that may be specified in writing from time to time by Agent,
and shall be credited and applied to the Guaranteed Obligations.

         2.3  Enforcement  of  Guaranty.  In  no  event  shall  Agent  have  any
              -------------------------
obligation  (although  it is  entitled,  at its  option) to proceed  against any
Borrower  or  any  other  Credit  Party  or any  Collateral  pledged  to  secure
Guaranteed  Obligations  before  seeking  satisfaction  from  any  or all of the
Guarantors,  and Agent may proceed,  prior or subsequent  to, or  simultaneously
with,  the  enforcement of Agent's  rights  hereunder,  to exercise any right or
remedy which it may have against any Collateral,  as a result of any Lien it may
have as security for all or any portion of the Guaranteed Obligations.

         2.4 Waiver. In addition to the waivers contained in Section 2.1 hereof,
             ------
Guarantors  waive,  and agree that they shall not at any time insist upon, plead
or in any  manner  whatever  claim or take the  benefit  or  advantage  of,  any
appraisal,  valuation, stay, extension, marshaling of assets or redemption laws,
or exemption,  whether now or at any time  hereafter in force,  which may delay,
prevent or otherwise  affect the  performance by Guarantors of their  Guaranteed
Obligations  under,  or the  enforcement  by Agent or Lenders of, this Guaranty.
Guarantors   hereby  waive  diligence,   presentment  and  demand  (whether  for
non-payment or protest or of acceptance,  maturity, extension of time, change in
                                                    

<PAGE>


nature or form of the Guaranteed  Obligations,  acceptance of further  security,
release of further security, composition or agreement arrived at as to the 
amount of, or the terms of,  the  Guaranteed  Obligations,  notice  of  adverse
change in any Borrower's  financial  condition or any other fact which might
increase the risk to Guarantors)  with respect to any of the  Guaranteed  
Obligations or all other demands  whatsoever  and waive the benefit of all
provisions of law which are or might be in  conflict  with the terms of this  
Guaranty.  Guarantors  represent, warrant and jointly and severally  agree that,
as of the date of this  Guaranty, their obligations under this Guaranty are not
subject to any offsets or defenses against  Agent or Lenders or any Credit 
Party of any kind.  Guarantors  further jointly and severally agree that their 
obligations under this Guaranty shall not be subject to any counterclaims, 
offsets or defenses against Agent or any Lender or against any Credit Party of
any kind which may arise in the future.

         2.5 Benefit of Guaranty.  The  provisions  of this Guaranty are for the
             -------------------
benefit  of Agent and  Lenders  and their  respective  successors,  transferees,
endorsees and assigns, and nothing herein contained shall impair, as between any
Credit Party and Agent or Lenders, the obligations of any Credit Party under the
Loan Documents.  In the event all or any part of the Guaranteed  Obligations are
transferred,  indorsed  or  assigned  by Agent or any  Lender  to any  Person or
Persons,  any  reference to "Agent" or "Lender"  herein shall be deemed to refer
equally to such Person or Persons.

         2.6 Modification of Guaranteed Obligations,  Etc. Each Guarantor hereby
             --------------------------------------------
acknowledges  and agrees  that Agent and Lenders may at any time or from time to
time, with or without the consent of, or notice to, Guarantors or any of them:

                  (a)      change or extend the manner, place or terms of 
payment of, or renew or alter all or any portion of, the Guaranteed Obligations;

                  (b) take any action under or in respect of the Loan  Documents
in the exercise of any remedy, power or privilege contained therein or available
to it at law, equity or otherwise,  or waive or refrain from exercising any such
remedies, powers or privileges;

                  (c)      amend or modify, in any manner whatsoever, the Loan
Documents;

                  (d)  extend  or  waive  the  time  for  any   Credit   Party's
performance of, or compliance with, any term,  covenant or agreement on its part
to be performed or observed under the Loan Documents,  or waive such performance
or compliance or consent to a failure of, or departure from, such performance or
compliance;

                  (e) take and hold Collateral for the payment of the Guaranteed
Obligations  guaranteed  hereby  or sell,  exchange,  release,  dispose  of,  or
otherwise deal with, any property  pledged,  mortgaged or conveyed,  or in which
Agent or Lenders have been granted a Lien, to secure any Obligations;

                  (f)  release  anyone  who may be liable in any  manner for the
payment of any amounts  owed by  Guarantors  or any Credit Party to Agent or any
Lender;

                  (g)  modify or  terminate  the terms of any  intercreditor  or
subordination  agreement  pursuant  to which  claims of other  creditors  of any
Guarantor  or any  Credit  Party  are  subordinated  to the  claims of Agent and
Lenders; and/or

                  (h) apply any sums by whomever paid or however realized to any
amounts  owing by any  Guarantor  or any Credit  Party to Agent or any Lender in
such manner as Agent or any Lender shall determine in its discretion;



<PAGE>

and Agent and Lenders  shall not incur any  liability to  Guarantors as a result
thereof,  and no such action shall impair or release the Guaranteed  Obligations
of Guarantors or any of them under this Guaranty.

         2.7 Reinstatement.  This Guaranty shall remain in full force and effect
             -------------
and  continue  to be  effective  should any  petition be filed by or against any
Credit Party or any  Guarantor for  liquidation  or  reorganization,  should any
Credit Party or any Guarantor  become  insolvent or make an  assignment  for the
benefit of creditors or should a receiver or trustee be appointed for all or any
significant  part of such Credit Party's or such Guarantor's  assets,  and shall
continue to be  effective or be  reinstated,  as the case may be, if at any time
payment and performance of the Guaranteed Obligations,  or any part thereof, is,
pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by Agent or any Lender, whether as a "voidable preference",
"fraudulent conveyance", or otherwise, all as though such payment or performance
had not been  made.  In the event  that any  payment,  or any part  thereof,  is
rescinded,  reduced,  restored or returned,  the Guaranteed Obligations shall be
reinstated  and deemed  reduced  only by such amount paid and not so  rescinded,
reduced, restored or returned.

         2.8  Deferral  of  Subrogation,  Etc.  Notwithstanding  anything to the
              -------------------------------
contrary in this Guaranty, or in any other Loan Document, each Guarantor hereby:

                  (a) expressly and irrevocably  waives, on behalf of itself and
its successors and assigns  (including any surety) until the  Termination  Date,
any and all  rights at law or in equity to  subrogation,  to  reimbursement,  to
exoneration,  to contribution,  to  indemnification,  to set off or to any other
rights that could accrue to a surety against a principal, to a guarantor against
a  principal,  to a guarantor  against a maker or obligor,  to an  accommodation
party against the party accommodated, to a holder or transferee against a maker,
or to the holder of any claim against any Person,  and which such  Guarantor may
have or hereafter  acquire  against any Credit Party in connection  with or as a
result  of such  Guarantor's  execution,  delivery  and/or  performance  of this
Guaranty,  or any  other  documents  to  which  such  Guarantor  is a  party  or
otherwise; and

                  (b)  acknowledges  and agrees (i) that this waiver is intended
to  benefit  Agent and  Lenders  and shall not  limit or  otherwise  effect  any
Guarantor's liability hereunder or the enforceability of this Guaranty, and (ii)
that Agent,  Lenders and their  respective  successors  and assigns are intended
third  party  beneficiaries  of the  waivers  and  agreements  set forth in this
Section 2.8 and their  rights under this  Section 2.8 shall  survive  payment in
full of the Guaranteed Obligations.

         2.9 Election of Remedies.  If Agent may, under  applicable law, proceed
             --------------------
to realize  benefits under any of the Loan Documents  giving Agent and Lenders a
Lien  upon  any  Collateral  owned  by any  Credit  Party,  either  by  judicial
foreclosure  or by  non-judicial  sale or  enforcement,  Agent may,  at its sole
option,  determine  which of such  remedies  or  rights  it may  pursue  without
affecting  any of such  rights  and  remedies  under this  Guaranty.  If, in the
exercise  of any of its rights and  remedies,  Agent  shall  forfeit  any of its
rights or remedies,  including its right to enter a deficiency  judgment against
any Credit Party, whether because of any applicable laws pertaining to "election
of remedies" or the like,  Guarantors hereby consent to such action by Agent and
waive any claim  based  upon such  action,  even if such  action by Agent  shall
result in a full or partial loss of any rights of subrogation  which  Guarantors
might otherwise have had but for such action by Agent.  Any election of remedies
which  results  in the  denial  or  impairment  of the  right of Agent to seek a
deficiency  judgment  against any Credit Party shall not impair each Guarantor's
obligation to pay the full amount of the  Guaranteed  Obligations.  In the event
Agent shall bid at any  foreclosure  or  trustee's  sale or at any private  sale
permitted  by law or the  Loan  Documents,  Agent  may bid all or less  than the
amount of the Guaranteed Obligations and the amount of such bid need not be paid
by Agent but shall be credited against the Guaranteed Obligations. The amount of
the successful bid at any such sale shall be conclusively  deemed to be the fair
market value of the collateral  and the  difference  between such bid amount and
the remaining balance of the Guaranteed Obligations shall be conclusively deemed
to be the amount of the Guaranteed  Obligations  guaranteed under this Guaranty,
notwithstanding  that any present or future law or court  decision or ruling may


<PAGE>

have the effect of reducing  the amount of any  deficiency  claim to which Agent
and Lenders might otherwise be entitled but for such bidding at any such sale.

         2.10 Funds Transfers.  If any Guarantor shall engage in any transaction
              ---------------
as a result of which any  Borrower is  required  to make a mandatory  prepayment
with  respect  to the  Guaranteed  Obligations  under  the  terms of the  Credit
Agreement  (including any issuance or sale of such Guarantor's Stock or any sale
of its assets),  such Guarantor  shall  distribute to, or make a contribution to
the capital of, one or more of the  Borrowers an amount  equal to the  mandatory
prepayment required under the terms of the Credit Agreement.

3.       DELIVERIES.
         ----------

         In a form  satisfactory  to Agent,  Guarantors  shall  deliver to Agent
(with  sufficient  copies for each Lender),  concurrently  with the execution of
this  Guaranty  and  the  Credit   Agreement,   the  Loan  Documents  and  other
instruments,  certificates  and  documents  as are  required to be  delivered by
Guarantors to Agent under the Credit Agreement.

4.       REPRESENTATIONS AND WARRANTIES.
         ------------------------------

         To  induce  Lenders  to make the  Loans  and  incur  Letter  of  Credit
Obligations  under the Credit Agreement,  Guarantors  jointly and severally make
the  representations and warranties as to each Guarantor contained in the Credit
Agreement,  each of which is incorporated herein by reference, and the following
representations  and warranties to Agent and each Lender,  each and all of which
shall survive the execution and delivery of this Guaranty:

         4.1 Corporate  Existence;  Compliance with Law. Each Guarantor (i) is a
             ------------------------------------------
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation;  (ii) is duly qualified to do business and
is in good standing under the laws of each  jurisdiction  where its ownership or
lease of property or the conduct of its business  requires  such  qualification;
(iii) has the  requisite  corporate  power and  authority and the legal right to
own,  pledge,  mortgage  and operate its  properties,  to lease the  property it
operates  under  lease,  and to conduct  its  business  as now,  heretofore  and
proposed to be conducted; (iv) has all licenses,  permits, consents or approvals
from or by, and has made all material  filings  with,  and has given all notices
to, all Governmental Authorities having jurisdiction, to the extent required for
such ownership, operation and conduct; (v) is in compliance with its charter and
by-laws; and (vi) is in compliance with all applicable provisions of law, except
where  the  failure  to  comply,  individually  or in the  aggregate,  could not
reasonably be expected to have a Material Adverse Effect.

of any  Governmental  Authority or any other Person except those  referred to in

accordance with its terms.

5.       FURTHER ASSURANCES.
         ------------------

         Each Guarantor agrees, upon the written request of Agent or any Lender,

         All payments  required to be made by each Guarantor  hereunder shall be
made to Agent and Lenders free and clear of, and without  deduction for, any and
all  present  and future  Taxes.  If any  Guarantor  shall be required by law to
deduct any Taxes from or in respect of any sum  payable  hereunder,  (a) the sum
payable  shall be  increased  as much as shall be necessary so that after making
all required  deductions  (including  deductions  applicable to additional  sums
payable under this Section 6) Agent or Lenders, as applicable, receive an amount
equal to the sum they would have received had no such  deductions been made, (b)
such Guarantor shall make such deductions,  and (c) such Guarantor shall pay the
full amount  deducted to the relevant  taxing or other  authority in  accordance
with  applicable  law.  Within thirty (30) days after the date of any payment of

certified copy of a receipt  evidencing  payment  thereof.  Each Guarantor shall
jointly and severally  indemnify and,  within ten (10) days of demand  therefor,
pay Agent and each  Lender  for the full  amount of Taxes  (including  any Taxes
imposed by any  jurisdiction  on amounts  payable  under this Section 6) paid by
Agent or such Lender, as appropriate,  and any liability  (including  penalties,
interest and expenses) arising therefrom or with respect thereto, whether or not
such Taxes were correctly or legally asserted.

             -------------------------------------------

writing, signed by Agent and then only to the extent therein set forth. A waiver
by Agent, for itself and the ratable benefit of Lenders,  of any right or remedy

remedy which Agent would otherwise have had on any future  occasion.  No failure
to exercise nor any delay in exercising on the part of Agent or any Lender,  any
right,  power or privilege  hereunder,  shall operate as a waiver  thereof,  nor

preclude  any other or future  exercise  thereof  or the  exercise  of any other
right,  power or  privilege.  The rights and  remedies  hereunder  provided  are
cumulative and may be exercised singly or concurrently, and are not exclusive of




<PAGE>


any rights and remedies provided by law. None of the terms or provisions of this
Guaranty may be waived,  altered,  modified,  supplemented or amended except by
an instrument in writing, duly executed by Agent and Guarantors.

              -----------
remain in full force and effect  until the  Termination  Date.  Upon payment and
performance  in full of the  Guaranteed  Obligations,  Agent  shall  deliver  to
Guarantors such documents as Guarantors may reasonably  request to evidence such
termination.

         7.8  Counterparts.  This  Guaranty  may be  executed  in any  number of
              ------------
counterparts, each of which shall collectively and separately constitute one and
the same agreement.

         7.9      GOVERNING LAW; CONSENT TO JURISDICTION AND VENUE.
                  ------------------------------------------------

         EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN ANY OF THE LOAN DOCUMENTS, IN
ALL RESPECTS,  INCLUDING ALL MATTERS OF CONSTRUCTION,  VALIDITY AND PERFORMANCE,
THIS GUARANTY AND THE  OBLIGATIONS  ARISING  HEREUNDER SHALL BE GOVERNED BY, AND
CONSTRUED  AND ENFORCED IN  ACCORDANCE  WITH,  THE LAWS OF THE STATE OF NEW YORK
APPLICABLE  TO CONTRACTS  MADE AND PERFORMED IN SUCH STATE,  AND ANY  APPLICABLE
LAWS OF THE UNITED STATES OF AMERICA.  EACH GUARANTOR HEREBY CONSENTS AND AGREES
THAT THE STATE OR  FEDERAL  COURTS  LOCATED IN NEW YORK,  SHALL  HAVE  EXCLUSIVE
JURISDICTION  TO HEAR AND  DETERMINE  ANY  CLAIMS OR  DISPUTES  BETWEEN OR AMONG
GUARANTORS,  AGENT OR ANY LENDER  PERTAINING  TO THIS  GUARANTY OR TO ANY MATTER
ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY OF THE OTHER LOAN  DOCUMENTS,
PROVIDED,  THAT AGENT AND  GUARANTORS  ACKNOWLEDGE  THAT ANY APPEALS  FROM THOSE
COURTS  MAY  HAVE TO BE HEARD  BY A COURT  LOCATED  OUTSIDE  OF NEW  YORK,  AND,
PROVIDED,  FURTHER,  THAT NOTHING IN THIS GUARANTY SHALL BE DEEMED OR OPERATE TO
PRECLUDE  AGENT FROM  BRINGING  SUIT OR TAKING  OTHER LEGAL  ACTION IN ANY OTHER
JURISDICTION  TO  REALIZE  ON THE  COLLATERAL  OR ANY  OTHER  SECURITY  FOR  THE
GUARANTEED  OBLIGATIONS,  OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR
OF AGENT, FOR THE BENEFIT OF AGENT AND LENDERS. EACH GUARANTOR EXPRESSLY SUBMITS
AND CONSENTS IN ADVANCE TO SUCH  JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN
ANY SUCH COURT, AND EACH GUARANTOR HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE
BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS
AND HEREBY  CONSENTS  TO THE  GRANTING OF SUCH LEGAL OR  EQUITABLE  RELIEF AS IS
DEEMED  APPROPRIATE BY SUCH COURT. EACH GUARANTOR HEREBY WAIVES PERSONAL SERVICE
OF THE SUMMONS,  COMPLAINT AND OTHER  PROCESS  ISSUED IN ANY SUCH ACTION OR SUIT
AND AGREES THAT SERVICE OF SUCH  SUMMONS,  COMPLAINTS  AND OTHER  PROCESS MAY BE
MADE BY REGISTERED OR CERTIFIED  MAIL ADDRESSED TO SUCH GUARANTOR AT THE ADDRESS
SET  FORTH  ON  SCHEDULE  I HERETO  AND THAT  SERVICE  SO MADE  SHALL BE  DEEMED
                -----------
COMPLETED  UPON THE  EARLIER OF ACTUAL  RECEIPT  THEREOF OR THREE (3) DAYS AFTER
DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE PREPAID.

         7.10     WAIVER OF JURY TRIAL.
                  --------------------

         BECAUSE   DISPUTES   ARISING  IN  CONNECTION  WITH  COMPLEX   FINANCIAL
TRANSACTIONS  ARE MOST QUICKLY AND  ECONOMICALLY  RESOLVED BY AN EXPERIENCED AND
EXPERT  PERSON AND THE PARTIES WISH  APPLICABLE  STATE AND FEDERAL LAWS TO APPLY
(RATHER THAN ARBITRATION  RULES), EACH GUARANTOR AND AGENT DESIRES THAT DISPUTES
ARISING  HEREUNDER  OR  RELATING  HERETO BE RESOLVED  BY A JUDGE  APPLYING  SUCH
APPLICABLE LAWS.  THEREFORE,  TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF
THE JUDICIAL  SYSTEM AND OR  ARBITRATION,  EACH  GUARANTOR  AND AGENT WAIVES ALL




<PAGE>


RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY
DISPUTE, WHETHER SOUNDING IN  CONTRACT,  TORT,  OR  OTHERWISE,  ARISING OUT OF,
CONNECTED  WITH, RELATED TO, OR INCIDENTAL TO THE  RELATIONSHIP  ESTABLISHED  
IN CONNECTION  WITH THIS GUARANTY AND THE OTHER LOAN DOCUMENTS OR THE 
TRANSACTIONS RELATED HERETO OR THERETO.

         7.11  Limitation  on  Guaranteed   Obligations.   Notwithstanding   any
               ----------------------------------------
provision herein contained to the contrary, each Guarantor's liability hereunder
shall be limited to an amount not to exceed as of any date of determination  the
greater of:

         (a)  the net  amount  of all  Loans  and  other  extensions  of  credit
(including  Letters of Credit)  advanced under the Credit Agreement and directly
or indirectly re-loaned or otherwise transferred to, or incurred for the benefit
of, such  Guarantor,  plus interest  thereon at the applicable rate specified in
the Credit Agreement; or

         (b) the amount  which  could be claimed by the Agent and  Lenders  from
such  Guarantor  under this Guaranty  without  rendering  such claim voidable or
avoidable  under Section 548 of Chapter 11 of the  Bankruptcy  Code or under any
applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent  Conveyance
Act or similar  statute or common law after  taking  into  account,  among other
things,  such Guarantor's  right of contribution and  indemnification  from each
other Guarantor under Section 7.12.

         7.12     Contribution with Respect to Guaranteed Obligations.
                  ---------------------------------------------------

         (a) To the extent that any  Guarantor  shall make a payment  under this
Guaranty of all or any of the  Guaranteed  Obligations  (a "Guarantor  Payment")
which,  taking into account all other  Guarantor  Payments  then  previously  or
concurrently  made by the  other  Guarantors,  exceeds  the  amount  which  such
Guarantor  would  otherwise  have paid if each  Guarantor had paid the aggregate
Guaranteed   Obligations  satisfied  by  such  Guarantor  Payment  in  the  same
proportion  that such  Guarantor's  "Allocable  Amount" (as  defined  below) (in
effect  immediately  prior  to such  Guarantor  Payment)  bore to the  aggregate
Allocable Amounts of all of Guarantors in effect immediately prior to the making
of such Guarantor Payment,  then, following indefeasible payment in full in cash
of the Obligations and termination of the  Commitments,  such Guarantor shall be
entitled to receive  contribution  and  indemnification  payments  from,  and be
reimbursed by, each of the other  Guarantors for the amount of such excess,  pro
rata based upon their respective  Allocable Amounts in effect  immediately prior
to such Guarantor Payment.

         (b) As of any date of  determination,  the  "Allocable  Amount"  of any
Guarantor  shall be equal to the maximum amount of the claim which could then be
recovered from such Guarantor under this Guaranty  without  rendering such claim
voidable or avoidable  under Section 548 of Chapter 11 of the Bankruptcy Code or
under any applicable state Uniform  Fraudulent  Transfer Act, Uniform Fraudulent
Conveyance Act or similar statute or common law.

         (c) This Section 7.12 is intended only to define the relative rights of
                  ------------
Guarantors  and nothing set forth in this  Section  7.12 is intended to or shall
                                           -------------
impair the obligations of Guarantors,  jointly and severally, to pay any amounts
as and when the same shall become due and payable in  accordance  with the terms
of this Guaranty.

         (d) The  rights  of the  parties  under  this  Section  7.12  shall  be
                                                        -------------
exercisable upon the full and indefeasible payment of the Guaranteed Obligations
and the termination of the Credit Agreement and the other Loan Documents.

         (e) The parties hereto  acknowledge that the rights of contribution and
indemnification hereunder shall constitute assets of any Guarantor to which such
contribution and indemnification is owing.

3.1 PAYMENT ON DEMAND. Guarantor agrees to make immediate payment to the
Guaranteed Parties, or any of them, of all Guaranteed Obligations owing or
payable to the Guaranteed Parties, or any of them, upon demand for payment
therefor by Agent to Guarantor.

3.2 NO SET-OFF. Each payment to be made by Guarantor hereunder in respect of the
Guaranteed Obligations shall be payable in the currency or currencies in which
such Guaranteed Obligations are denominated, and shall be made:

         (1)      without set-off or counterclaim; and

         (2)      free and clear of and without deduction or withholding for or
                  on account of any present and future taxes, levies, imposts,
                  stamp taxes, duties, charges to tax, fees, deductions,
                  withholdings and any conditions or restrictions resulting in
                  charges to tax and all penalties, interest and other payments
                  on or in respect thereof ("TAX" or "TAXES") unless Guarantor
                  is compelled by law to make payment subject to such Taxes.

3.3 TAXES. All Taxes in respect of this Guarantee or any amounts payable or paid
under this Guarantee shall be paid by Guarantor when due and in any event prior
to the date on which penalties attach thereto. Guarantor will indemnify each of
the Guaranteed Parties against and in respect of all such Taxes.

3.4 TAX GROSS-UP. Without limiting the generality of the foregoing, if any Taxes
or amounts in respect thereof must be deducted or withheld from any amounts
payable or paid by Guarantor hereunder, Guarantor shall pay such additional
amounts as may be necessary to ensure that each of the Guaranteed Parties
receives a net amount equal to the full amount which it would have received had
payment (including of any additional amounts payable under this Section 3.4) not
been made subject to such Taxes. Within thirty (30) days of each payment by
Guarantor hereunder of Taxes or in respect of Taxes, Guarantor shall deliver to
Agent satisfactory evidence (including originals, or certified copies, of all
relevant receipts) that such Taxes have been duly remitted to the appropriate
authority or authorities.

SECTION 4 -- OBLIGATIONS ABSOLUTE

4.1 OBLIGATIONS ABSOLUTE. The obligations of Guarantor hereunder are and shall
be absolute and unconditional and any monies or amounts expressed to be owing or
payable by Guarantor hereunder which may not be recoverable from Guarantor on
the footing of a guarantee shall be recoverable from Guarantor as a primary
obligor and principal debtor in respect thereof; provided however that this
Section 4.1 shall not be construed as conferring on Guarantor any rights or
benefits that Guarantor would have in law or equity under any of the Loan
Documents if it were an Obligor. Guarantor agrees that any notice or directive
given at any time to Agent that is inconsistent with the Guarantor being a
principal debtor with respect to the Guaranteed Obligations shall be null and
void and may be ignored by Agent, and, in addition, may not be pleaded or
introduced as evidence in any litigation relating to this Guarantee for the

<PAGE>

reason that such pleading or introduction would be at variance with the written
terms of this Guarantee, unless Agent has specifically agreed otherwise in
writing. This Guarantee is a guarantee of payment and performance and not of
collection.

SECTION 5 -- INDEMNITY

5.1 INDEMNITY. As an original and independent obligation under this Guarantee,
Guarantor shall:

         (1)      indemnify each of the Guaranteed Parties and keep each of the
                  Guaranteed Parties indemnified against any cost, loss, expense
                  or liability of whatever kind resulting from the failure by
                  any Obligor to make due and punctual payment of any of the
                  Guaranteed Obligations or resulting from any of the Guaranteed
                  Obligations being or becoming void, voidable, unenforceable or
                  ineffective against any Obligor (including, but without
                  limitation, all reasonable legal fees and disbursements and
                  other costs, charges and expenses incurred by the Guaranteed
                  Parties, or any of them, in connection with preserving or
                  enforcing, or attempting to preserve or enforce, their rights
                  under this Guarantee); and

         (2)      pay on demand the amount of such cost, loss, expense or
                  liability whether or not any of the Guaranteed Parties have
                  attempted to enforce any rights against any Obligor or any
                  other Person or otherwise.

SECTION 6 -- OBLIGATIONS CONTINUING

6.1 NO REDUCTION. The obligations of Guarantor hereunder shall be continuing and
shall remain in full force and effect until the Termination Date. The
obligations of Guarantor hereunder shall not be satisfied, reduced, affected or
discharged by any intermediate payment, settlement or satisfaction of the whole
or any part of the principal, interest, fees and other monies or amounts which
may at any time be or become owing or payable under or by virtue of or otherwise
in connection with the Guaranteed Obligations or the Loan Documents.

6.2 EFFECT OF RECISION. The obligations of Guarantor hereunder shall continue to
be effective or shall be reinstated, as the case may be, if at any time any
payment which would otherwise have reduced the obligations of Guarantor
hereunder (whether such payment shall have been by or on behalf of any Obligor,
or by or on behalf of Guarantor) is rescinded or reclaimed from any of the
Guaranteed Parties upon the insolvency, bankruptcy, liquidation or
reorganization of any Obligor or Guarantor or otherwise, all as though such
payment had not been made.

SECTION 7 -- OBLIGATIONS NOT AFFECTED

7.1 OBLIGATIONS NOT AFFECTED. The obligations of Guarantor hereunder shall not
be affected or impaired by any act, omission, matter or thing whatsoever,
occurring before, upon or after any demand for payment hereunder (and whether or
not known to Guarantor or any of the Guaranteed Parties) which, but for this
provision, might constitute a whole or partial defence to a claim against
Guarantor hereunder or might operate to release or otherwise exonerate Guarantor

<PAGE>

from any of its obligations hereunder or otherwise affect such obligations,
whether occasioned by default of Agent or any of the Lenders or otherwise, and,
to the extent waivable under applicable law, Guarantor hereby irrevocably waives
any defence it may now or hereafter have in any way relating to any of the
foregoing, including, without limitation:

         (1)      any limitation of status or power, disability, incapacity or
                  other circumstance relating to Guarantor, any other Obligor,
                  or any other Person, including any insolvency, bankruptcy,
                  liquidation, reorganization, readjustment, composition,
                  dissolution, winding-up or other proceeding involving or
                  affecting Guarantor, any other Obligor or any other Person;

         (2)      any irregularity, defect, unenforceability or invalidity in
                  respect of any indebtedness or other obligation of Guarantor,
                  any other Obligor or any other Person under the Loan Documents
                  or any other agreement, document or instrument;

         (3)      any failure of any other Obligor, or any other Person, whether
                  or not without fault on their part, to perform or comply with
                  any of the provisions of the Loan Documents or to give notice
                  thereof to Guarantor;

         (4)      the taking or enforcing or exercising or the refusal or
                  neglect to take or enforce or exercise any right or remedy
                  against any other Obligor or any other Person (including,
                  without limitation, rights and remedies granted under the Loan
                  Documents) or their respective assets, or the release or
                  discharge of any such right or remedies;

         (5)      the granting of time, renewals, extensions, compromises,
                  concessions, waivers, consents, releases, discharges and other
                  indulgences to any Obligor or any other Person;

         (6)      any amendment, restatement, variation, modification,
                  supplement or replacement of the Loan Documents or any other
                  agreement, document or instrument to which Guarantor, any
                  other Obligor or any other Person is or may become a party;

         (7)      any change in the ownership, control, name, objects,
                  businesses, assets, capital structure or constitution of
                  Guarantor, any other Obligor or any other Person;

         (8)      any merger or amalgamation of Guarantor or any other Obligor
                  with any Person or Persons;

         (9)      the occurrence of any change in the laws, rules, regulations
                  or ordinances of any jurisdiction or by any present or future
                  action of any governmental body or court amending, varying,
                  reducing or otherwise affecting, or purporting to amend, vary,
                  reduce or otherwise affect, any of the Guaranteed Obligations
                  or the obligations of Guarantor under this Guarantee;


<PAGE>
         (10)     the existence, value or condition of, or the failure to
                  perfect Agent's Liens against, any collateral for the
                  Guaranteed Obligations, or any action, or the absence of any
                  action, by Agent and Lenders or any of them in respect thereof
                  (including the release of any such security);

         (11)     the existence of any claim, set-off or other rights which
                  Guarantor may have at any time against any other Obligor, the
                  Guaranteed Parties, or any other Person, or which any other
                  Obligor may have at any time against the Guaranteed Parties,
                  whether in connection with the Loan Documents or otherwise;
                  and

         (12)     any other circumstance (including, without limitation, any
                  existence of or reliance on any representation by Agent, but
                  excluding complete, irrevocable payment) that might otherwise
                  constitute a legal or equitable discharge or defence of
                  Guarantor or any other Obligor under the Loan Documents
                  including, without limitation, those of Guarantor in respect
                  of its guarantee hereunder.

Guarantor acknowledges and agrees that the waivers set out in this Section 7.1,
and in Section 4.1 are of the essence of the transaction contemplated by the
Credit Agreement and the other Loan Documents and that, but for this Guarantee
and such waivers, Agent and Lenders would decline to enter into the Credit
Agreement.

7.2 WAIVER. Without in any way limiting the provisions of Section 7.1 of this
Guarantee, Guarantor hereby waives notice of acceptance hereof, notice of any
liability of Guarantor hereunder, notice or proof of reliance by the Guaranteed
Parties upon the obligations of Guarantor hereunder, and diligence, presentment,
demand for payment on Guarantor or any other Obligor, protest, notice of
dishonour or non-payment of any of the Guaranteed Obligations, or other notice
or formalities to Guarantor or any other Obligor, of any kind whatsoever.

7.3 NO OBLIGATION TO TAKE ACTION AGAINST OBLIGOR. Neither Agent nor any of the
other Guaranteed Parties shall have any obligation to enforce any rights or
remedies or to take any other steps against any Obligor, or any other Person or
any property of any Obligor, or any other Person before Agent is entitled to
demand payment and performance by Guarantor of its liabilities and obligations
under this Guarantee, and Guarantor hereby waives all benefit of discussion. The
obligations of Guarantor hereunder are independent of the Guaranteed Obligations
and a separate action or actions may be brought and prosecuted against Guarantor
to enforce this Guarantee, irrespective of whether any action is brought against
any other Obligor or whether any other Obligor is joined in any such action or
actions.

7.4 DEALING WITH OBLIGORS AND OTHERS. The Guaranteed Parties, without releasing,
discharging, limiting or otherwise affecting in whole or in part Guarantor's
obligations and liabilities hereunder and without the consent of or notice to
Guarantor, may:

         (1)      grant time, renewals, extensions, compromises, concessions,
                  waivers, releases, discharges and other indulgences to any
                  Obligor or any other Person;

         (2)      amend, vary, modify, supplement or replace any Loan Document


<PAGE>
                  or any other related document or instrument;

         (3)      take or abstain from taking securities or collateral from any
                  Obligor, or from perfecting securities or collateral of any
                  Obligor;

         (4)      release, discharge, compromise, realize, enforce or otherwise
                  deal with or do any act or thing in respect of (with or
                  without consideration) any and all collateral, mortgages or
                  other security given by any Obligor or any third party with
                  respect to the obligations or matters contemplated by the
                  Credit Agreement;

         (5)      accept compromises or arrangements from any Obligor;

         (6)      apply all monies at any time received from any Obligor, or
                  from any collateral upon such part of the Guaranteed
                  Obligations as they may see fit or change any such application
                  in whole or in part from time to time as they may see fit; and

         (7)      otherwise deal with, or waive or modify their right to deal
                  with any Obligor and all other Persons and securities as they
                  may see fit.

7.5 ACKNOWLEDGEMENT. Guarantor hereby acknowledges communication of the terms of
the Loan Documents and of all the provisions therein contained and consents to
and approves the same. Guarantor hereby represents and warrants that there are
no conditions precedent to the effectiveness of this Guarantee that have not
been satisfied or waived.

7.6 ACCOUNTS STATED. Guarantor shall be bound by any account settled between any
Obligor and the Guaranteed Parties, and if no such account has been so settled
immediately before demand for payment under this Guarantee, any account stated
by Agent shall be accepted by Guarantor as prima facie evidence in the absence
of manifest error of the amount which at the date of the account so stated is
due by such Obligor to the Guaranteed Parties or remains unpaid by such Obligor
to the Guaranteed Parties.

7.7 POSTPONEMENT. Until the Guaranteed Obligations are paid and otherwise
satisfied in full and Guarantor has satisfied all of its obligations pursuant to
this Guarantee including, without limitation, pursuant to Section 3.1 of this
Guarantee, all indebtedness and liabilities, present and future, of each Obligor
to Guarantor, and all notes and instruments evidencing such indebtedness and
liabilities, are hereby assigned to the Guaranteed Parties and postponed to the
liabilities to the Guaranteed Parties and all moneys received by Guarantor in
respect of the indebtedness and liabilities of each Obligor to Guarantor shall
be received in trust for the Guaranteed Parties and forthwith upon receipt shall
be paid over to Agent on behalf of the Guaranteed Parties, the whole without in
any way limiting or lessening the liability of Guarantor under the guarantee
contained in this Guarantee. This assignment and postponement is independent of
such guarantee and shall remain in full effect notwithstanding that the
liability of Guarantor under such guarantee may be extinct; provided that
nothing in this Section 7.7 shall restrict in any way any payments in respect of
the indebtedness and liabilities of any Obligor to Guarantor which are permitted
by the Credit Agreement.

SECTION 8  --  REPRESENTATIONS AND WARRANTIES OF GUARANTOR

8.1 REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants to Agent
on behalf of the Guaranteed Parties as follows and acknowledges and confirms
that the Guaranteed Parties are relying upon such representations and
warranties:

         (1)      Guarantor is a corporation duly incorporated and validly

                  authorized by all necessary corporate action, does not
                  contravene any law or governmental regulation or any

         (3)      no authorization or approval or other action by, and no notice
                  to or filing with, any governmental body is required for the
                  due execution, delivery and performance by Guarantor of this
                  Guarantee;

         (4)      Guarantor is the direct or indirect beneficial owner of all of
                  the capital stock of each of the other Obligors (other than
                  Controlled Power Limited Partnership) and
                  is the direct or indirect beneficial owner of all of the
                  capital stock of each of the general and limited partners of
                  Controlled Power Limited Partnership;

         (5)      the execution, delivery and performance of the Guarantor's
                  obligations under this Guarantee will not result in a breach
                  of any agreement to which Guarantor is a party or by which
                  Guarantor or its property is bound; and

         (6)      this Guarantee is a legal, valid and binding obligation of
                  Guarantor, enforceable against Guarantor in accordance with
                  its terms subject to (i) applicable bankruptcy, insolvency,
                  reorganization, moratorium or similar laws affecting the
                  enforcement of creditors' rights generally and (ii) the fact
                  that specific performance and injunctive relief may be given
                  at the discretion of the court.

SECTION 9 -- GENERAL

9.1 NOTICES. Except as otherwise provided herein, each notice, demand, request,
consent, approval, declaration or other communication which shall or may be
given hereunder shall be in writing and shall be deemed to have been validly
served, given or delivered if served, given or delivered in accordance with
Section 11.10 of the Credit Agreement. The giving of any notice to any party
hereunder may be waived in writing by such party.

9.2 AMENDMENT. No modification, variation or amendment of any provision of this
Guarantee shall be made except by a written agreement, executed by the parties
hereto and no waiver of any provision hereof shall be effective unless in
writing.


<PAGE>

9.3 SUCCESSOR AGENT. In the event that Agent for the time being under the Credit
Agreement shall resign or be removed and a successor agent thereafter shall be
appointed in accordance with Section 9.7 of the Credit Agreement, then upon such
successor agent agreeing in writing to be bound by the provisions of this
Guarantee as Agent hereunder, all references herein to Agent in this Guarantee
shall be deemed to be references to such successor agent as and from such date
and such successor agent shall receive and become vested with all the rights,
powers, privileges and duties of the retiring or removed Agent and the retiring
or removed Agent shall be discharged from its further duties and obligations as
Agent under this Guarantee.

9.4 JUDGMENT CURRENCY. If for the purposes of obtaining judgment in any court in
any jurisdiction with respect to this Guarantee it becomes necessary to convert
into the currency of such jurisdiction (herein called the "JUDGMENT CURRENCY")
any amount due hereunder in any currency other than the Judgment Currency, then
conversion shall be made at the rate of exchange prevailing on the Business Day
before the day on which judgment is given. For this purpose, "rate of exchange"
means the rate at which Agent would, on the relevant date at or about 12:00 noon
(New York time), be prepared to sell a similar amount of such currency in New
York against the Judgment Currency. In the event that there is a change in the
rate of exchange prevailing between the Business Day before the day on which the
judgment is given and the date of payment of the amount due, Guarantor will, on
the date of payment, pay such additional amounts (if any) as may be necessary 
to ensure that the amount paid on such date is the amount in the Judgment     
Currency which when converted at the rate of exchange prevailing on the date of
payment is the amount then due under this Guarantee in such other currency. Any
additional amount due from Guarantor under this Section 9.4 will be due as a 
separate debt and shall not be affected by judgment being obtained for any other
sums due under or in respect of this Guarantee.

9.5 APPLICABLE LAW. This Guarantee shall be conclusively deemed to be a contract
made under, and shall for all purposes be governed by, and construed and
interpreted in accordance with, the laws of the Province of Ontario and the
federal laws of Canada applicable therein in effect from time to time without
prejudice to or limitation of any other rights or remedies available under the
laws of any jurisdiction where property or assets of Guarantor may be found.

9.6 JURISDICTION.

         (1)      Guarantor irrevocably agrees that any suits, actions or
                  proceedings arising out of or in connection with this
                  Guarantee (collectively "PROCEEDINGS") may be brought in any
                  New York State Court or U.S. Federal Court sitting in the
                  State of New York and submits and attorns to the non-exclusive
                  jurisdiction of each such court.

         (2)      Guarantor irrevocably waives any objections which it may have
                  now or hereafter to the laying of the venue of any Proceedings
                  in any court referred to in paragraph (a) and any claim that
                  any such Proceedings have been brought in an inconvenient
                  forum and further irrevocably agrees that a judgment in any
                  Proceedings brought in any such court shall be conclusive and
                  binding upon Guarantor and may be enforced in any courts to
                  the jurisdiction of which such parties may be subject by

<PAGE>

                  Proceedings upon such judgment.

         (3)      Nothing contained in this Section 9.6 shall limit the right of
                  Agent or any other Guaranteed Party to take Proceedings
                  against Guarantor in any other court of competent jurisdiction
                  nor shall the taking of Proceedings in one or more
                  jurisdictions preclude the taking of Proceedings in any other
                  jurisdiction, whether concurrently or not.

         (4)      Guarantor hereby irrevocably consents generally to the fullest
                  extent permitted by law in respect of any Proceedings to the
                  giving of any relief and the issue of any process in
                  connection with such Proceedings including, without
                  limitation, the making, enforcement or execution against any
                  property whatsoever (irrespective of its use or intended use)
                  of any order or judgment which may be made or given in such
                  Proceedings.

         (5)      Guarantor hereby irrevocably waives all right to trial by jury
                  in any action, proceeding or counterclaim (whether based on
                  contract, tort or otherwise) arising

<PAGE>


                  out of or relating to the Loan Documents or this Guarantee,
                  the transactions contemplated hereby or thereby or the actions
                  of any Guaranteed Party in the negotiation, administration,
                  performance or enforcement hereof or thereof.

9.7 COSTS AND EXPENSES. Guarantor shall pay on demand by Agent any and all
reasonable costs, fees and expenses (including, without limitation, reasonable
legal fees and expenses) incurred by Agent in enforcing any of its rights under
this Guarantee.

9.8 NO WAIVER, CUMULATIVE REMEDIES. Agent's or any Lender's failure, at any time
or times, to require strict performance by Guarantor of any provision of this
Guarantee shall not waive, affect or diminish any right of Agent or such Lender
thereafter to demand strict compliance and performance therewith. Any suspension
or waiver of an Event of Default shall not suspend, waive or affect any other
Event of Default whether the same is prior or subsequent thereto and whether the
same or of a different type. Agent's and Lenders' rights and remedies under this
Guarantee shall be cumulative and nonexclusive of any other rights and remedies
which Agent or any Lender may have under any other agreement, including the
other Loan Documents, by operation of law or otherwise. Recourse to the
Collateral shall not be required. No single or partial exercise by Agent or
Lender of any right or remedy precludes or otherwise affects the exercise of any
other right or remedy to which that party may be entitled.

9.9 WAIVER OF RIGHTS OF SUBROGATION, REIMBURSEMENT, ETC. Guarantor hereby
irrevocably waives any claim or other rights that it may now or hereafter
acquire against any Obligor that arise from the existence, payment, performance
or enforcement of the Guaranteed Obligations under this Guarantee, the Credit
Agreement or any other Loan Document, including, without limitation, any right
of subrogation, reimbursement, exoneration, contribution or indemnification and
any right to participate in any claim or remedy of the Guaranteed Parties
against any Obligor, or any collateral, whether or not such claim, remedy or
right arises in equity or under contract, statute or common law, including,
without limitation, the right to take or receive from any Obligor, directly or

indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim, remedy or right; provided,
however, that such waiver shall terminate at such time, if any, as the
Guaranteed Obligations and all other amounts payable under this Guarantee have
been paid in full and all obligations of the Guaranteed Parties under the Loan
Documents have terminated; provided that Agent shall be entitled to hold any
Potential Preference Payment (as hereafter defined) in trust for the benefit of
the Guaranteed Parties and shall forthwith pay such amount to the Guaranteed
Parties, to be credited and applied following the expiry of the potential
preference period, to the Guaranteed Obligations, whether matured or unmatured,
in accordance with the terms of the Credit Agreement. The term "POTENTIAL
PREFERENCE PAYMENT" shall mean any payment or other transfer received for the
benefit of the Guaranteed Parties for or on account of the Guaranteed
Obligations which could be avoided by a trustee in bankruptcy for any Obligor,
or by or for the benefit of other creditors of any Obligor as a "preference" or
a "preferential transfer" or for any other reason under any applicable
bankruptcy, insolvency or similar law now or hereafter in effect in any
bankruptcy, insolvency or similar proceeding with respect to any Obligor.
Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Credit Agreement and that the 
waiver set forth in this Section 9.9 is knowingly made in contemplation of such
benefits.

9.10 GUARANTEE IN ADDITION TO OTHER OBLIGATIONS. The obligations of Guarantor
under this Guarantee are in addition to and not in substitution for any other
obligations to Agent or to any of the other Guaranteed Parties in relation to
the Loan Documents and any guarantees, indemnities or security at any time held
by or for the benefit of any of them.

9.11 ENTIRE AGREEMENT. This Guarantee, including all documents contemplated
hereby, constitutes the entire agreement between the parties with respect to the
subject matter and supersedes all prior negotiations, undertakings,
representations and understandings.

9.12 SEVERABILITY. Any provision of this Guarantee which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions
and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

9.13 SUCCESSORS AND ASSIGNEES. This Guarantee shall be binding upon and enure to
the benefit of Guarantor and Agent and the other Guaranteed Parties and their
respective successors and permitted assignees, except that Guarantor may not
assign any of its obligations hereunder.
