Item 5. Other Events.
        -------------

Revolving Credit Facility

        The Company entered into a Revolving Credit Facility (the "Revolving
Credit Facility") pursuant to a Loan and Security Agreement dated as of June 23,
1998, (the "Loan Agreement") with BankAmerica Business Credit, Inc. ("BABC"), as
agent, and Deutsche Financial Services Corporation, as administrative agent.
Under, the Revolving Credit Facility, ABT has a maximum borrowing availability
of up to $100 million, and may borrow, repay and reborrow revolving loans and
request BABC as agent to cause letters of credit to be issued for the account of
the Company. The Revolving Credit Facility expires on June 23, 2001. As of July
8, 1998, the Company had borrowed approximately $35 million. The proceeds of the
Revolving Credit Facility will be used for working capital and other general 
corporate purposes.

        The Company may elect to borrow revolving loans under the Revolving
Credit Facility as "LIBOR Loans" or "Base Rate Loans." Base Rate Loans are loans
that bear interest at a variable rate equal to the "reference rate" of Bank of
America National Trust and Savings and Association (the "Bank") plus 1.125% and
LIBOR Loans bear interest at a variable rate of interest equal to the applicable
"London Interbank Offered Rate" of the Bank plus 2.375% for a one, two or three
month interest period, as selected by the Company.

        The Revolving Credit Facility is secured by collateral consisting of
substantially all the assets (excluding fixed assets and real property) of the
Company and its subsidiaries in which a security interest may lawfully be
granted, including, without limitation, accounts receivable, inventory,
intellectual property, and all of the capital stock of the Company's
subsidiaries. Each of the Company's domestic subsidiaries is a co-borrower under
the Revolving Credit Facility and new acquisitions are required to become co-
borrowers by signing a joinder agreement. The terms of the Revolving Credit
Facility contain operating and financial covenants, including, without
limitation, requirements to maintain minimum ratios of cash flow to debt service
and a maximum ratio of total debt to equity.

Bridge Facility

        The Company has entered into a bridge loan facility (the "Bridge
Facility") pursuant to a Bridge Loan Agreement dated as of July 3, 1998 with
Deutsche Bank AG, New York Branch, which provides for $15 million of unsecured
bridge financing in connection with certain pending acquisitions. The Bridge
Facility matures on January 4, 1999 and consists of Base Rate Loans and Euro-
Dollar Rate Loans. The interest rate is 3.50% above the Base Rate or the Euro-
Dollar Rate prior to September 7, 1998, increasing to 7.50% per annum at any
time on or after November 7, 1998.

the Aggregate Revolver Outstandings exceed the Availability (with the
Availability for this purpose calculated as if the Aggregate Revolver
Outstandings were zero), the Lenders may refuse to make or otherwise restrict
the making of Revolving Loans as the Lenders determine until such excess has
been eliminated, subject to the Agent's authority, in its sole discretion, to

Pro Rata Share of the requested Borrowing available to the Agent in same day
funds, to such account of the Agent as the Agent may designate, not later than
12:00 noon, (Los Angeles, California time) on the Funding Date applicable
thereto.  After the Agent's receipt of the proceeds of such Revolving Loans,
upon satisfaction of the applicable conditions precedent set forth in Article
                                                                      -------

in no event exceed the Availability on such date.

          (ii)  Unless the Agent receives notice from a Lender on or prior to
the Closing Date or, with respect to any Borrowing after the Closing Date, at
least one Business Day prior to the date of such Borrowing, that such Lender
will not make available as and when required hereunder to the Agent for the
account of the Borrowers the amount of that Lender's Pro Rata Share of the
Borrowing, the Agent may assume that each Lender has made such amount available
to the Agent in immediately available funds on the Funding Date and the Agent
may (but shall not be so required), in reliance upon such assumption, make
available to the Borrowers on such date a corresponding amount.  If and to the
extent any Lender shall not have made its full amount available to the Agent in
immediately available funds and the Agent in such circumstances has made
available to the Borrowers such amount, that Lender shall on the Business Day
following such Funding Date make such amount available to the Agent, together
with interest at the Federal Funds Rate for each day during such period.  A
notice of the Agent submitted to any Lender with respect to amounts owing under
this subsection shall be conclusive, absent manifest error.  If such 

                                      -38-
<PAGE>
 
amount is so made available, such payment to the Agent shall constitute such
Lender's Loan on the payment date for all purposes of this Agreement. If such
amount is not made available to the Agent on the Business Day following the
Funding Date, the Agent will notify ABT of such failure to fund and, upon demand
by the Agent, the Borrowers shall pay such amount to the Agent for the Agent's
account, together with interest thereon for each day elapsed since the date of
such Borrowing, at a rate per annum equal to the Interest Rate applicable at the
time to the Loans comprising such Borrowing. The failure of any Lender to make
any Loan on any Funding Date (any such Lender, prior to the cure of any such
failure to fund any Loan required to be made by such Lender, being hereinafter
referred to as a "Defaulting Lender") shall not relieve any other Lender of any
obligation hereunder to make a Loan on such Funding Date, but no Lender shall be
responsible for the failure of any other Lender to make the Loan to be made by
such other Lender on any Funding Date.

          (iii)  The Agent shall not be obligated to transfer to a Defaulting
Lender any payments made by Borrowers to the Agent for the Defaulting Lender's
benefit; nor shall a Defaulting Lender be entitled to the sharing of any
payments hereunder.  Amounts payable to a Defaulting Lender shall instead be
paid to or retained by the Agent.  The Agent may hold and, in its discretion,
re-lend to Borrowers the amount of all such payments received or retained by it
for the account of such Defaulting Lender.  Any amounts so re-lent to the
Borrowers shall bear interest at the rate applicable to Base Rate Revolving
Loans and for all other purposes of this Agreement shall be treated as if they
were Revolving Loans, provided, however, that for purposes of voting or
consenting to matters with respect to the Loan Documents and determining Pro
Rata Shares, such Defaulting Lender shall be deemed not to be a "Lender" and
such Lender's Commitment shall be deemed to be zero (-0-). Until a Defaulting
Lender cures its failure to fund its Pro Rata Share of any Borrowing (1) such
Defaulting Lender shall not be entitled to any portion of the Unused Line Fee
and (2) the Unused Line Fee shall accrue in favor of the Lenders which have
funded their respective Pro Rata Shares of such requested Borrowing and shall be
allocated among such performing Lenders ratably based upon their relative
Commitments.  This Section shall remain effective with respect to such Lender
until such time as the Defaulting Lender shall no longer be in default of any of
its obligations under this Agreement.  The terms of this Section shall not be
construed to increase or otherwise affect the Commitment of any Lender, or
relieve or excuse the performance by the Borrowers of their duties and
obligations hereunder.

          (h)  Making of BABC Loans.  (i) In the event the Agent shall elect,
               --------------------                                          
with the consent of BABC, to have the terms of this Section 2.2(h) apply to a
                                                    --------------           
requested Borrowing as described in Section 2.2(f), BABC shall make a Revolving
                                    --------------                             
Loan in the amount of such Borrowing (any such Revolving Loan made solely by
BABC pursuant to this Section 2.2(h) being referred to as a "BABC Loan" and such
                      --------------                                            
Revolving Loans being referred to collectively as "BABC Loans") available to the
Borrowers on the Funding Date applicable thereto by transferring same day funds
to an account of the Borrowers, designated in writing by the Borrowers and
acceptable to the Agent.  Each BABC Loan is a Revolving Loan hereunder and shall
be subject to all the terms and conditions applicable to other Revolving Loans
except that all payments thereon shall be payable to BABC solely for its own
account (and for the account of the holder of any participation interest with
respect to such Revolving Loan).  The Agent shall not request BABC to make any
BABC Loan if (i) the Agent shall have received written notice from any Lender,
or otherwise has actual knowledge, that one or more of the applicable conditions
precedent set forth in Article 10 will not be satisfied on the requested Funding
                       ----------                                               
Date for the applicable Borrowing, or (ii) the requested Borrowing would exceed
the Availability on such Funding Date, or (iii) the requested Borrowing would
cause the unpaid balance of all BABC Loans to exceed $10,000,000.  BABC shall
not otherwise be required to determine whether the applicable conditions
precedent set forth in Article 10 have been satisfied or the requested Borrowing
                       ----------                                               
would exceed the Availability on the Funding Date applicable thereto prior to
making, in its sole discretion, any BABC Loan.

          (ii)  The BABC Loans shall be secured by the Collateral, shall
constitute Revolving Loans and Obligations hereunder, and shall bear interest at
the rate applicable to the Revolving Loans from time to time.

          (i)  Agent Advances.  (i) Subject to the limitations set forth in the
               --------------                                                  
provisos contained in this Section 2.2(i), the Agent is hereby authorized by the
                           --------------                                       
Borrowers and the Lenders, from time to time in the Agent's sole discretion, (1)
after the occurrence of a Default or an Event of Default, or (2) at any time
that any of the other applicable conditions precedent set forth in Article 10
                                                                   ----------
have not been satisfied, to make Revolving Loans to the Borrowers on behalf of
the Lenders which the Agent, in its reasonable business judgment, deems
necessary or desirable (A) to preserve or protect the Collateral, or any portion
thereof, (B) to enhance the likelihood of, or maximize the amount of, repayment
of the Loans and other Obligations, or (C) to pay any other amount chargeable to

                                      -40-

the Borrowers pursuant to the terms of this Agreement, including, without
limitation, costs, fees and expenses as described in Section 15.7 (any of the
                                                     ------------            
advances described in this Section 2.2(i) being hereinafter referred to as
                           --------------                                 
"Agent Advances"); provided, that the Required Lenders may at any time revoke
                   --------                                                  
the Agent's authorization contained in this Section 2.2(i) to make Agent
                                            --------------              
Advances, any such revocation to be in writing and to become effective
prospectively upon the Agent's receipt thereof;

          (ii)  The Agent Advances shall be repayable on demand and secured by
the Collateral, shall constitute Revolving Loans and Obligations hereunder, and
shall bear interest at the rate applicable to the Revolving Loans from time to
time.  The Agent shall notify each Lender in writing of each such Agent Advance.

          (j)  Settlement.  It is agreed that each Lender's funded portion of
               ----------                                                    
the Revolving Loan is intended by the Lenders to be equal at all times to such
Lender's Pro Rata Share of the outstanding Revolving Loans.  Notwithstanding
such agreement, the Agent, BABC, and the other Lenders agree (which agreement
shall not be for the benefit of or enforceable by any Borrower) that in order to
facilitate the administration of this Agreement and the other Loan Documents,
settlement among them as to the Revolving Loans, the BABC Loans and the Agent
Advances shall take place on a periodic basis in accordance with the following
provisions:

          (i)  The Agent shall request settlement ("Settlement") with the
Lenders on a weekly basis, or on a more frequent basis if so determined by the
Agent, (1) on behalf of BABC, with respect to each outstanding BABC Loan, (2)
for itself, with respect to each Agent Advance, and (3) with respect to
collections received, in each case, by notifying the Lenders of such requested
Settlement by telecopy, telephone or other similar form of transmission, of such
requested Settlement, no later than 10:00 a.m. (Los Angeles, California time) on
the date of such requested Settlement (the "Settlement Date").  Each Lender
(other than BABC, in the case of BABC Loans) shall make the amount of such
Lender's Pro Rata Share of the outstanding principal amount of the BABC Loans
and Agent Advances with respect to which Settlement is requested available to
the Agent, for itself or for the account of BABC, in same day funds, to such
account of the Agent as the Agent may designate, not later than 12:00 noon (Los
Angeles, California time), on the Settlement Date applicable thereto, regardless
of whether the applicable conditions precedent set forth in Article 10 have then
                                                            ----------          
been satisfied.  Such amounts made available to the Agent shall be applied
against the amounts of the applicable BABC Loan or Agent 

                                      -41-
<PAGE>
 
Advance and, together with the portion of such BABC Loan or Agent Advance
representing BABC's Pro Rata Share thereof, shall constitute Revolving Loans of
such Lenders. If any such amount is not made available to the Agent by any
Lender on the Settlement Date applicable thereto, the Agent shall be entitled to
recover such amount on demand from such Lender together with interest thereon at
the Federal Funds Rate for the first three (3) days from and after the
Settlement Date and thereafter at the Interest Rate then applicable to the
Revolving Loans.

          (ii)  Notwithstanding the foregoing, not more than one (1) Business
Day after demand is made by the Agent (whether before or after the occurrence of
a Default or an Event of Default and regardless of whether the Agent has
requested a Settlement with respect to a BABC Loan or Agent Advance), each other
Lender shall irrevocably and unconditionally purchase and receive from BABC or
the Agent, as applicable, without recourse or warranty, an undivided interest
and participation in such BABC Loan or Agent Advance to the extent of such
Lender's Pro Rata Share thereof by paying to the Agent, in same day funds, an
amount equal to such Lender's Pro Rata Share of such BABC Loan or Agent Advance.
If such amount is not in fact made available to the Agent by any Lender, the
Agent shall be entitled to recover such amount on demand from such Lender
together with interest thereon at the Federal Funds Rate for the first three (3)
days from and after such demand and thereafter at the Interest Rate then
applicable to the Revolving Loans.

          (iii)  From and after the date, if any, on which any Lender purchases
an undivided interest and participation in any BABC Loan or Agent Advance
pursuant to subsection (ii) above, the Agent shall promptly distribute to such
Lender at such address as such Lender may request in writing, such Lender's Pro
Rata Share of all payments of principal and interest and all proceeds of
Collateral received by the Agent in respect of such BABC Loan or Agent Advance.

          (iv)  Between Settlement Dates, the Agent, to the extent no Agent
Advances or BABC Loans are outstanding, may pay over to BABC any payments
received by the Agent, which in accordance with the terms of this Agreement
would be applied to the reduction of the Revolving Loans, for application to
BABC's other outstanding Revolving Loans.  If, as of any Settlement Date,
collections received since the then immediately preceding Settlement Date have
been applied to BABC's other outstanding Revolving Loans other than 

                                      -42-
<PAGE>
 
to BABC Loans or Agent Advances, as provided for in the previous sentence, BABC
shall pay to the Agent for the accounts of the Lenders, to be applied to the
outstanding Revolving Loans of such Lenders, an amount such that each Lender
shall, upon receipt of such amount, have, as of such Settlement Date, its Pro
Rata Share of the Revolving Loans. During the period between Settlement Dates,
BABC with respect to BABC Loans, the Agent with respect to Agent Advances, and
each Lender with respect to the Revolving Loans other than BABC Loans and Agent
Advances, shall be entitled to interest at the applicable rate or rates payable
under this Agreement on the actual average daily amount of funds employed by
BABC, the Agent and the other Lenders.

          (k)  Notation.  The Agent shall record on its books the principal
               --------                                                    
amount of the Revolving Loans owing to each Lender, including the BABC Loans
owing to BABC, and the Agent Advances owing to the Agent, from time to time.  In
addition, each Lender is authorized, at such Lender's option, to note the date
and amount of each payment or prepayment of principal of such Lender's Revolving
Loans in its books and records, including computer records, such books and
records constituting rebuttably presumptive evidence, absent manifest error, of
the accuracy of the information contained therein.

          (l)  Lenders' Failure to Perform.  All Loans (other than BABC Loans
               ---------------------------                                   
and Agent Advances) shall be made by the Lenders simultaneously and in
accordance with their Pro Rata Shares.  It is understood that (a) no Lender
shall be responsible for any failure by any other Lender to perform its
obligation to make any Loans hereunder, nor shall any Commitment of any Lender
be increased or decreased as a result of any failure by any other Lender to
perform its obligation to make any Loans hereunder, (b) no failure by any Lender
to perform its obligation to make any Loans hereunder shall excuse any other
Lender from its obligation to make any Loans hereunder, and (c) the obligations
of each Lender hereunder shall be several, not joint and several.

Credit or the Agent shall have made any payment pursuant to any Credit Support
and the Borrower shall not have repaid such amount to the issuer of such Letter
of Credit or the Agent, as applicable, pursuant to Section 2.4(e)(1), the Agent

each Lender shall make available to the Agent the amount of such payment, as
provided in the immediately preceding sentence, on such Business Day. Such
amounts paid by the Lenders to the Agent shall constitute Revolving Loans which
shall be deemed to have been requested by the Borrowers pursuant to Section 2.2
                                                                    -----------

the issuance of such Letter of Credit, equal to such Lender's Pro Rata Share of

(including, without limitation, all obligations of the Borrowers with respect
thereto, and any security therefor or guaranty pertaining thereto).

          (2) Sharing of Reimbursement Obligation Payments. Whenever the Agent
              --------------------------------------------                    
receives a payment from the Borrowers on account of reimbursement obligations in
respect of a Letter of Credit or Credit Support as to which the Agent has
previously received for the account of the issuer thereof payment from a Lender
pursuant to Section 2.4(e)(2), the Agent shall promptly pay to such Lender such
            -----------------                                                  
Lender's Pro Rata Share of such payment from the Borrowers in Dollars.  Each

      3.1  Interest.
           -------- 

          (a) Interest Rates.  All outstanding Obligations shall bear interest
              --------------                                                  
on the unpaid principal amount thereof (including, to the extent permitted by
law, on interest thereon not paid when due) from the date made until paid in
full in cash at a rate determined by reference to the Base Rate or the LIBOR
Rate and Sections 3.1(a)(i) or (ii), as applicable, but not to exceed the
         ------------------    ----                                      
Maximum Rate described in Section 3.3.  Subject to the provisions of Section

3.2, any of the Loans may be converted into, or continued as, Base Rate Loans or
- ---
LIBOR Rate Loans in the manner provided in Section 3.2.  If at any time Loans
                                           -----------                       
are outstanding with respect to which notice has not been delivered to the Agent
in accordance with the terms of this Agreement specifying the basis for
determining the interest rate applicable thereto, then those Loans shall be Base
Rate Loans and shall bear interest at a rate determined by reference to the Base
Rate until notice to the contrary has been given to the Agent in accordance with
this Agreement and such notice has become effective.  Except as otherwise
provided herein, the outstanding Obligations shall bear interest as follows:

                                      -52-

Each change in the Base Rate shall be reflected in the interest rate described
in clause (i) above as of the effective date of such change.  All interest
charges shall be computed on the basis of a year of 360 days and actual days
elapsed (which results in more interest being paid than if computed on the basis
of a 365-day year).   Interest accrued on all Loans will be payable in arrears
on the first day of each month hereafter.

          (b) Default Rate.  If any Default or Event of Default occurs and is
              ------------

any such Default or Event of Default is outstanding, all of the Obligations
shall bear interest at the Default Rate applicable thereto.

respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $1,000,000, such LIBOR Rate Loans shall
automatically convert into Base Rate Loans, and on and after such date the right
of the Borrower to continue such Loans as, and convert such Loans into, LIBOR
Rate Loans, as the case may be, shall terminate.

               (ii)  the aggregate amount of Loans to be converted or renewed;

conversion or continuation.

          (c) If upon the expiration of any Interest Period applicable to LIBOR
Rate Loans, the Borrower has failed to select timely a new Interest Period to be
applicable to LIBOR Rate Loans or if any Default or Event of Default then
exists, the Borrower shall be deemed to have elected to convert such LIBOR Rate
Loans into Base Rate Loans effective as of the expiration date of such Interest
Period.

          (d) The Agent will promptly notify each Lender of its receipt of a
Notice of Conversion/Continuation.  All conversions and continuations shall be

Rate Loan.

          (f) After giving effect to any conversion or continuation of Loans,
there may not be more than five (5) different Interest Periods in effect.

      3.3 Maximum Interest Rate.  In no event shall any interest rate provided

applicable law for loans of the type provided for hereunder (the "Maximum
Rate").  If, in any month, any interest rate, absent such limitation, would have
exceeded the Maximum Rate, then the interest rate for that month shall be the
Maximum Rate, and, if in future months, that interest rate would 

                                      -54-
<PAGE>
 
otherwise be less than the Maximum Rate, then that interest rate shall remain at
the Maximum Rate until such time as the amount of interest paid hereunder equals
the amount of interest which would have been paid if the same had not been
limited by the Maximum Rate. In the event that, upon payment in full of the
Obligations, the total amount of interest paid or accrued under the terms of
this Agreement is less than the total amount of interest which would, but for
this Section 3.3, have been paid or accrued if the interest rates otherwise 
     ----------- 
set forth in this Agreement had at all times been in effect, then the Borrowers
shall, to the extent permitted by applicable law, pay the Agent, for the account
of the Lenders, an amount equal to the excess of (a) the lesser of (i) the
amount of interest which would have been charged if the Maximum Rate had, at all
times, been in effect or (ii) the amount of interest which would have accrued
had the interest rates otherwise set forth in this Agreement, at all times, been
in effect over (b) the amount of interest actually paid or accrued under this
Agreement. In the event that a court determines that the Agent and/or any Lender
has received interest and other charges hereunder in excess of the Maximum Rate,
such excess shall be deemed received on account of, and shall automatically be
applied to reduce, the Obligations other than interest, in the inverse order of
maturity, and if there are no Obligations outstanding, the Agent and/or such
Lender shall refund to the Borrowers such excess.

      3.4  Closing Fee. The Borrowers agree to pay the Agent the fees set forth
           -----------

      3.5  Unused Line Fee.  Until the Obligations have been paid in full and
           ---------------

month and on the Termination Date, to the Agent, for the ratable account of the
Lenders, an unused line fee equal to one-quarter of one percent (.25%) per annum
on the average daily amount by which the Maximum Revolver Amount exceeded the
sum of the average daily outstanding amount of Revolving Loans and the undrawn
face amount of all outstanding Letters of Credit, during the immediately
preceding month or shorter period if calculated on the Termination Date.  The
unused line fee shall be computed on the basis of a 360-day year for the actual
number of days elapsed.

      3.6  Letter of Credit Fee.  The Borrowers agree to pay to the Agent, for
           --------------------

"Letter of Credit Fee") equal to one and one-quarter of one percent (1.25%) per
annum of the undrawn face amount of each Letter of Credit issued for the
Borrowers' account at the

                     ----                              
by the Agent in connection with the application for, issuance of, or amendment
to any Letter of Credit, which costs, fees and expenses could include a
"fronting fee" required to be paid by the Agent to such issuer for the
assumption of the settlement risk in connection with the issuance of such Letter
of Credit; the Letter of Credit Fee shall be payable monthly in arrears on the
first day of each month following any month in which a Letter of Credit was
issued and/or in which a Letter of Credit remains outstanding. The Letter of
Credit Fee shall be computed on the basis of a 360-day year for the actual
number of days elapsed.

the case may be.

          (c) Unless the Agent receives notice from the Borrowers prior to the
date on which any payment is due to the Lenders that the Borrowers will not make
such payment in full as and when required, the Agent may assume that the
Borrowers have made such payment in full to the Agent on such date in
immediately available funds and the Agent may (but shall not be so required), in
reliance upon such assumption, distribute to each Lender on such due date an
amount equal to the amount then due such Lender.  If and to the extent the
Borrowers have not made such payment in full to the Agent, each Lender shall
repay to the Agent on demand such amount distributed to such Lender, together
with interest thereon at the Federal Funds Rate for each day from the date such
amount is distributed to such Lender until the date repaid.

                                     ----- 
Obligation due to the Agent or any Lender by the Borrower. Notwithstanding
anything to the contrary contained in this Agreement, unless so directed by the
Borrower, or unless an Event of Default is outstanding, neither the Agent nor
any Lender shall apply any payments which it receives to any LIBOR Revolving
Loan, except (a) on the expiration date of the Interest Period applicable to any
such LIBOR Rate Loan, or (b) in the event, and only to the extent, that there
are no outstanding Base Rate Revolving Loans. The Agent shall promptly
distribute to each Lender, pursuant to the applicable wire transfer instructions
received from each Lender in writing, such funds as it may be entitled to
receive, subject to a Settlement delay as provided for in Section 2.2(j). The

Agent and the Lenders shall have the continuing and exclusive right to apply

of, or proceeds applied to the payment of, all or any part of the Obligations,
the Agent or any Lender is for any reason compelled to surrender such payment or
proceeds to any Person, because such payment or application of proceeds is
invalidated, declared fraudulent, set aside, determined to be void or voidable
as a preference, impermissible setoff, or a diversion of trust funds, or for any
other reason, then the Obligations or part thereof intended to be satisfied
shall be revived and continue and this Agreement shall continue in full force as
if such payment or proceeds had not been received by the Agent or such Lender,
and the Borrowers shall be liable to pay to the Agent, and hereby does indemnify
the Agent and the Lenders and hold the Agent and the Lenders harmless for, the
amount of such payment or proceeds

                                      -59-

surrendered. The provisions of this Section 4.9 shall be and remain effective

notwithstanding any contrary action which may have been taken by the Agent or
any Lender in reliance upon such payment or application of proceeds, and any
such contrary action so taken shall be without prejudice to the Agent's and the
Lenders' rights under this Agreement and shall be deemed to have been
conditioned upon such payment or application of proceeds having become final and
irrevocable. The provisions of this Section 4.9 shall survive the
                                    -----------
termination of this Agreement.

      4.1 Agent's and Lenders' Books and Records; Monthly Statements. The

Borrowers agree that the Agent's and each Lender's books and records showing the
Obligations and the transactions pursuant to this Agreement and the other Loan
Documents shall be admissible in any action or proceeding arising therefrom, and
shall constitute rebuttably presumptive proof thereof, irrespective of whether
any Obligation is also evidenced by a promissory note or other instrument.  The
Agent will provide to ABT a monthly statement of Loans, payments, and other
transactions pursuant to this Agreement.  Such statement shall be deemed
correct, accurate, and binding on the Borrowers and an account stated (except
for reversals and reapplications of payments made as provided in Section 4.8 and
                                                                 -----------    
corrections of errors discovered by the Agent), unless ABT notifies the Agent in
writing to the contrary within sixty (60) days after such statement is rendered.
In the event a timely written notice of objections is given by ABT, only the
items to which exception is expressly made will be considered to be disputed by
the Borrowers.

                     TAXES, YIELD PROTECTION AND ILLEGALITY
                     --------------------------------------

      5.1  Taxes. (a)  Any and all payments by the Borrowers to each Lender or
           -----                                                              
the Agent under this Agreement and any other Loan Document shall be made free
and clear of, and without deduction or withholding for any Taxes.  In addition,
the Borrowers shall pay all Other Taxes.

          (b) The Borrowers agree to indemnify and hold harmless each Lender and
the Agent for the full amount of Taxes or Other Taxes (including any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section)
paid by the Lender or the Agent and any liability arising therefrom or with

                                      -60-
<PAGE>
 
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted.  As of the Closing Date, neither the Borrowers nor the Agent
are aware of any such Taxes or Other Taxes. Payment under this indemnification
shall be made within 30 days after the date the Lender or the Agent makes
written demand therefor.

          (c) If the Borrowers shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to any
Lender or the Agent, then:

             (i)  the sum payable shall be increased as necessary so that after
making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this Section) such
Lender or the Agent, as the case may be, receives an amount equal to the sum it
would have received had no such deductions or withholdings been made;

            (ii)  the Borrowers shall make such deductions and withholdings;

           (iii)  the Borrowers shall pay the full amount deducted or withheld
to the relevant taxing authority or other authority in accordance with
applicable law; and
  
            (iv)  the Borrowers shall also pay to each Lender or the Agent for
the account of such Lender, at the time interest is paid, all additional amounts
which the respective Lender specifies as necessary to preserve the after-tax
yield the Lender would have received if such Taxes or Other Taxes had not been
imposed.

        (d) Within 30 days after the date of any payment by the Borrower of
Taxes or Other Taxes, the Borrowers shall furnish the Agent the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Agent.

        (e) If the Borrowers are required to pay additional amounts to any
Lender or the Agent pursuant to subsection (c) of this Section, then such Lender
shall use reasonable efforts (consistent with legal and regulatory restrictions)
to change the jurisdiction of its lending office so as to eliminate any such
additional payment by the Borrowers which may thereafter accrue, if such change
in the judgment of such Lender is not otherwise disadvantageous to such Lender.

      5.2  Illegality.  (a)  If any Lender determines that the introduction of
           ----------                                                         
any Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Lender or its applicable lending office to make
LIBOR Rate Loans, then, on notice thereof by the Lender to ABT through the
Agent, any obligation of that Lender to make LIBOR Rate Loans shall be suspended
until the Lender notifies the Agent and ABT that the circumstances giving rise
to such determination no longer exist.

          (b) If a Lender determines that it is unlawful to maintain any LIBOR
Rate Loan, the Borrowers shall, upon its receipt of notice of such fact and
demand from such Lender (with a copy to the Agent), prepay in full such LIBOR
Rate Loans of that Lender then outstanding, together with interest accrued
thereon and amounts required under Section 5.4, either on the last day of the
                                   -----------                               
Interest Period thereof, if the Lender may lawfully continue to maintain such
LIBOR Rate Loans to such day, or immediately, if the Lender may not lawfully
continue to maintain such LIBOR Rate Loan. If the Borrowers are required to so
prepay any LIBOR Rate Loan, then concurrently with such prepayment, the
Borrowers shall borrow from the affected Lender, in the amount of such
repayment, a Base Rate Loan.

      5.3  Increased Costs and Reduction of Return.  (a)  If any Lender
           ----------------------------------------                    
determines that, due to either (i) the introduction of or any change in the
interpretation of any law or regulation or (ii) the compliance by that Lender
with any guideline or request from any central bank or other Governmental
Authority (whether or not having the force of law), there shall be any increase
in the cost to such Lender of agreeing to make or making, funding or maintaining
any LIBOR Rate Loans, then the Borrowers shall be liable for, and shall from
time to time, upon demand (with a copy of such demand to be sent to the Agent),
pay to the Agent for the account of such Lender, additional amounts as are
sufficient to compensate such Lender for such increased costs.

          (b) If any Lender shall have determined that (i) the introduction of
any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy
Regulation, (iii) any change in the interpretation or administration of any
Capital Adequacy Regulation by any central bank or other Governmental Authority
charged with the interpretation or administration thereof, or (iv) compliance by

                                      -62-
<PAGE>
 
the Lender or any corporation or other entity controlling the Lender with any
Capital Adequacy Regulation, affects or would affect the amount of capital
required or expected to be maintained by the Lender or any corporation or other
entity controlling the Lender and (taking into consideration such Lender's or
such corporation's or other entity's policies with respect to capital adequacy
and such Lender's desired return on capital) determines that the amount of such
capital is increased as a consequence of its Commitments, loans, credits or
obligations under this Agreement, then, upon demand of such Lender to ABT
through the Agent, the Borrowers shall pay to the Lender, from time to time as
specified by the Lender, additional amounts sufficient to compensate the Lender
for such increase.  The Agent and Lender agree to give Borrowers ninety (90)
days notice prior to the date such amounts would become effective.  During such
90-day period Borrowers may terminate the Agreement with the early termination
fee described in Section 4.2 becoming zero irrespective of the date terminated.
                 -----------                                                   

      5.4  Funding Losses.  The Borrowers shall reimburse each Lender and hold
           --------------                                                     
each Lender harmless from any loss or expense which the Lender may sustain or
incur as a consequence of:

          (a) the failure of the Borrowers to make on a timely basis any payment
of principal of any LIBOR Rate Loan;

          (b) the failure of the Borrowers to borrow, continue or convert a Loan
after ABT has given (or is deemed to have given) a Notice of Borrowing or a
Notice of Conversion/ Continuation;

          (c) the prepayment or other payment (including after acceleration
thereof) of an LIBOR Rate Loan on a day that is not the last day of the relevant
Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its LIBOR Rate Loans or from fees payable to
terminate the deposits from which such funds were obtained.

      5.5  Inability to Determine Rates.  If the Agent determines that for any
           ----------------------------                                       
reason adequate and reasonable means do not exist for determining the LIBOR Rate
for any requested Interest Period with respect to a proposed LIBOR Rate Loan, or
that the LIBOR Rate for any requested Interest Period with respect to a proposed
LIBOR Rate Loan does not adequately and fairly reflect the cost to the Lenders
of funding such Loan, the Agent will promptly so notify ABT and

                                      -63-
<PAGE>
 
each Lender. Thereafter, the obligation of the Lenders to make LIBOR Rate Loans
hereunder shall be suspended until the Agent revokes such notice in writing.
Upon receipt of such notice, ABT may revoke any Notice of Borrowing or Notice of
Conversion/Continuation then submitted by it. If ABT does not revoke such
Notice, the Lenders shall make, convert or continue the Loans, as proposed by
the Borrowers, in the amount specified in the applicable notice submitted by
ABT, but such Loans shall be made, converted or continued as Base Rate Loans
instead of LIBOR Rate Loans.

      5.6  Certificates of Lenders.  Any Lender claiming reimbursement or
           -----------------------                                       
compensation under this Article 5 shall deliver to ABT (with a copy to the
Agent) a certificate setting forth in reasonable detail the amount payable to
the Lender hereunder and such certificate shall be conclusive and binding on the
Borrowers in the absence of manifest error.

      5.7  Survival.  The agreements and obligations of the Borrowers in this
           --------

               (viii)  all books, records and other property related to or
referring to any of the foregoing, including, without limitation, books,
records, account ledgers, data processing records, computer software and other
property and General Intangibles at any time evidencing or relating to any of
the foregoing; and

                 (iv)  all accessions to, substitutions for and replacements,
products and proceeds of any of the foregoing, including, but not limited to,
proceeds of any insurance policies, except insurance pertaining to Fixed Assets,
claims against third parties, and condemnation or requisition payments with
respect to all or any of the foregoing.

All of the foregoing, and all other property of the Borrower in which the Agent
or any Lender may at any time be granted a Lien, is herein collectively referred
to as the "Collateral."

          (b) All of the Obligations shall be secured by all of the Collateral.

      6.2 Perfection and Protection of Security Interest. With respect to each
          ----------------------------------------------                      
Borrower:

          (a)  Each Borrower shall, at its expense, perform all steps requested
by the Agent at any time to perfect, maintain, protect, and enforce the Agent's
Liens, including, without limitation:  (i) executing, delivering and/or filing
and recording of the Patent and Trademark Agreements and executing and filing
financing or continuation statements, and amendments thereof, in form and
substance satisfactory to the Agent; (ii) delivering to the Agent the originals
of all instruments, documents, and chattel paper, and all other Collateral of
which the Agent determines it should have 

                                      -65-
<PAGE>
 
physical possession in order to perfect and protect the Agent's security
interest therein, duly pledged, endorsed or assigned to the Agent without
restriction; (iii) delivering to the Agent warehouse receipts covering any
portion of the Collateral located in warehouses and for which warehouse receipts
are issued and certificates of title covering any portion of the collateral for
which certificates of title have been issued; (iv) when an Event of Default
exists, transferring Inventory to warehouses designated by the Agent; (v)
placing notations on the Borrower's books of account to disclose the Agent's
security interest; (vii) delivering to the Agent all letters of credit on which
the Borrower is named beneficiary; and (viii) taking such other steps as are
deemed necessary or desirable by the Agent to maintain and protect the Agent's
Liens. To the extent permitted by applicable law, the Agent may file, without
the Borrower's signature, one or more financing statements disclosing the
Agent's Liens. The Borrower agrees that a carbon, photographic, photostatic, or
other reproduction of this Agreement or of a financing statement is sufficient
as a financing statement.

          (b) If any Collateral is at any time in the possession or control of
any warehouseman, bailee or any of the Borrower's agents or processors, then the
Borrower shall notify the Agent thereof and shall, at the request of Agent
following an Event of Default, notify such Person of the Agent's security
interest in such Collateral and instruct such Person to hold all such Collateral
for the Agent's account subject to the Agent's instructions.  Unless an Event of
Default has occurred, Agent agrees to instruct such Person to accept Borrower's
instructions until further notice from Agent.  If at any time any Collateral is
located on any operating facility of the Borrower which is not owned by the
Borrower, then the Borrower shall, at the request of the Agent, obtain written
waivers, in form and substance satisfactory to the Agent, of all present and
future Liens to which the owner or lessor  of such premises may be entitled to
assert against the Collateral.

          (c) From time to time, the Borrower shall, upon the Agent's request,
execute and deliver confirmatory written instruments pledging to the Agent, for
the ratable benefit of the Agent and the Lenders, the Collateral with respect to
the Borrower, but the Borrower's failure to do so shall not affect or limit any
security interest or any other rights of the Agent or any Lender in and to the
Collateral with respect to the Borrower.  So long as this Agreement is in effect
and until all Obligations have been fully satisfied, the Agent's Liens shall
continue in full force and 

                                      -66-
<PAGE>
 
effect in all Collateral (whether or not deemed eligible for the purpose of
calculating the Availability or as the basis for any advance, loan, extension of
credit, or other financial accommodation).

      6.3 Location of Collateral.  Each Borrower represents and warrants to the
          ----------------------                                               
Agent and the Lenders that:  (a) Schedule 6.3 is a correct and complete list of
                                 ------------                                  
the Borrower's chief executive office, the location of its books and records,
the locations of the Collateral, and the locations of all of its other places of
business; and (b) Schedule 6.3 correctly identifies any of such facilities and
                  ------------                                                
locations that are not owned by the Borrower and sets forth the names of the
owners, consignees, processors, warehousemen, and lessors or sublessors of and,
to the best of the Borrower's knowledge, the holders of any mortgages on, such
facilities and locations.  Each Borrower covenants and agrees that it will not
(i) maintain any Collateral at any location other than those locations listed
for the Borrower on Schedule 6.3, (ii) otherwise change or add to any of such
                    ------------                                             
locations, or (iii) change the location of its chief executive office from the
location identified in Schedule 6.3, unless it gives the Agent at least twenty
                       ------------                                           
(20) days' prior written notice thereof and executes any and all financing
statements and other documents that the Agent requests in connection therewith.
Without limiting the foregoing, each Borrower represents that all of its
Inventory (other than Inventory in transit) is, and covenants that all of its
Inventory will be, located either (a) on premises owned by the Borrower, (b) on
premises leased by the Borrower, provided that the Agent has, if requested by
the Agent, received an executed landlord waiver from the landlord of such
premises in form and substance satisfactory to the Agent, or (c) in a public
warehouse, provided that the Agent has, if requested by the Agent, received an
executed bailee letter from the applicable public warehouseman in form and
substance satisfactory to the Agent.  All Key Locations are set forth on Exhibit
                                                                         -------
"I".  ABT shall notify the Agent two (2) days after any location becomes a Key
- ---                                                                           
Location and will submit to Agent an updated Exhibit "I".  ABT will have thirty
                                             -----------                       
(30) days from the date a location becomes a Key Location to obtain the
appropriate documentation described in Subsections (b) and (c) above. Thereafter
all Inventory located at such Key Location will be ineligible unless and until
such documentation has been obtained.

      6.4 Title to, Liens on, and Sale and Use of Collateral.  Each Borrower
          --------------------------------------------------                
represents and warrants to the Agent and the Lenders and agrees with the Agent
and the Lenders that: (a) all of the Collateral is and will continue to be owned
by the Borrower free 

                                      -67-
<PAGE>
 
and clear of all Liens whatsoever, except for Permitted Liens; (b) the Agent's
Liens in the Collateral will not be subject to any prior Lien except for
Permitted Liens; (c) the Borrower will use, store, and maintain the Collateral
with all reasonable care and will use such Collateral for lawful purposes only;
and (d) the Borrower will not, without the Agent's prior written approval, sell,
or dispose of or permit the sale or disposition of any of the Collateral except
for sales of Inventory in the ordinary course of business. The inclusion of
proceeds in the Collateral shall not be deemed to constitute the Agent's or any
Lender's consent to any sale or other disposition of the Collateral except as
expressly permitted herein.

      6.5 Appraisals.  Whenever a Default or Event of Default exists, the
          ----------                                                     
Borrowers shall, at their expense and upon the Agent's request, provide the
Agent with appraisals or updates thereof of any or all of the Collateral from an
appraiser, and prepared on a basis, satisfactory to the Agent, such appraisals
and updates to include, without limitation, information required by applicable
law and regulation and by the internal policies of the Lenders.

      6.6 Access and Examination; Confidentiality.  (a)  The Agent, accompanied
          ---------------------------------------                              
by any Lender which so elects, may at all reasonable times during regular
business hours and upon at least two Business Day's advance notice to ABT(and at
any time and without notice when a Default or Event of Default exists and is
continuing) have access to, examine, audit, make extracts from or copies of and
inspect any or all of the Borrower's records, files, and books of account and
the Collateral, and discuss any Borrower's affairs with such Borrower's officers
and management.  Each Borrower will deliver to the Agent any instrument
necessary for the Agent to obtain records from any service bureau maintaining
records for the Borrower.  The Agent may, and at the direction of the Majority
Lenders shall, at any time when a Default or Event of Default exists, and at the
Borrowers' expense, make copies of all of the Borrowers' books and records, or
require each Borrower to deliver such copies to the Agent.  The Agent may,
without expense to the Agent, use such of the Borrowers' respective personnel,
supplies, and premises as may be reasonably necessary for maintaining or
enforcing the Agent's Liens.  The Agent shall have the right, at any time, in
the Agent's name or in the name of a nominee of the Agent, to verify the
validity, amount or any other matter relating to the Accounts, Inventory, or
other Collateral, by mail, telephone, or otherwise.

          (b) Each Borrower agrees that, subject to the Borrower's prior consent
for uses other than in a traditional tombstone, which 

                                      -68-
<PAGE>
 
consent shall not be unreasonably withheld or delayed, the Agent and each Lender
may use the Borrower's name in advertising and promotional material and in
conjunction therewith disclose the general terms of this Agreement. The Agent
and each Lender agree to take normal and reasonable precautions and exercise due
care to maintain the confidentiality of all information identified as
"confidential" or "secret" by the Borrower and provided to the Agent or such
Lender by or on behalf of the Borrower, under this Agreement or any other Loan
Document. Borrowers hereby notify Agent and Lenders that all information
previously provided or to be provided to Agent and/or Lenders should be deemed
to be identified as "confidential" or "secret". Neither the Agent, nor such
Lender nor any of their respective Affiliates shall use any such information
other than in connection with or in enforcement of this Agreement and the other
Loan Documents, except to the extent that such information (i) was or becomes
generally available to the public other than as a result of disclosure by the
Agent or such Lender, or (ii) was or becomes available on a nonconfidential
basis from a source other than the Borrower, provided that such source is not
bound by a confidentiality agreement with the Borrower known to the Agent or
such Lender; provided, however, that the Agent and any Lender may disclose such
             --------  -------
information (1) at the request or pursuant to any requirement of any
Governmental Authority to which the Agent or such Lender is subject or in
connection with an examination of the Agent or such Lender by any such
Governmental Authority; (2) pursuant to subpoena or other court process; (3)
when required to do so in accordance with the provisions of any applicable
requirement of law; (4) to the extent reasonably required in connection with any
litigation or proceeding and as required by court order (including, but not
limited to, any bankruptcy proceeding) to which the Agent, any Lender or their
respective Affiliates may be party; (5) to the extent reasonably required in
connection with the exercise of any remedy hereunder or under any other Loan
Document; (6) to the Agent's or such Lender's independent auditors, accountants,
attorneys and other professional advisors provided they agree to maintain the
confidentiality of such information; (7) to any prospective Participant or
assignee under any Assignment and Acceptance, actual or potential, provided that
such prospective Participant or assignee agrees to keep such information
confidential to the same extent required of the Agent and the Lenders hereunder;
(8) as expressly permitted under the terms of any other document or agreement
regarding confidentiality to which the Borrower is party or is deemed party with
the Agent or such Lender, and (9) to its Affiliates. With respect to any
disclosure under subsections (2), (4) and (5) above, the Agent shall notify the
Borrowers as promptly as practicable of the receipt of a request for disclosure
and furnish Borrowers with a copy of such request or legal process and comply
and cooperate with 

                                      -69-
<PAGE>
 
Borrowers' reasonable requests and attempts to maintain the confidentiality of
such information.

      6.7 Collateral Reporting.  ABT shall provide the Agent with the following
          --------------------                                                 
documents at the following times in form satisfactory to the Agent on a
consolidating basis by Borrower and Canadian Guarantor: (a) if Availability is
less than $25,000,000 on a weekly basis, or, if Availability is equal to or

have been issued since the last such schedule and a Borrowing Base Certificate;
(b) on a monthly basis to be received by Agent by the twentieth day of the
following month, or more frequently if requested by Agent following a Default,
an aging of the Borrowers' Accounts, together with a reconciliation to the
Borrowers' general ledger and a calculation of the ineligible Accounts; (c) on a
monthly basis to be received by Agent by the twentieth day of the following
month, or more frequently if requested by Agent following a Default, an aging of
the Borrowers' accounts payable; (d) on a monthly basis to be received by Agent
by the twentieth day of the following month (or more frequently if requested by
the Agent following a Default), Inventory reports by category (including, but
not limited to, Inventory held by Borrower on consignment), location and, if
such location is not owned by Borrower, what, if any, relationship exists with
the owner of such location (i.e. consignee, processor, warehouseman), whether
such location is a Key Location, with additional detail showing additions to and
deletions from the Inventory, a reconciliation to the Borrower's general ledger
and a calculation of the ineligible Inventory; (e) upon request, copies of
invoices in connection with the Borrowers' Accounts, customer statements, credit

of the Borrowers executed by an officer thereof certifying as to the accuracy
and completeness of the foregoing.  If any of the Borrowers' records or reports
of the Collateral are prepared by an accounting service or other agent, the
Borrowers hereby authorize such service or agent to deliver such records,
reports, and related documents to the Agent, for distribution to the Lenders.

                                      -70-
<PAGE>
 
      6.8 Accounts.  (a) Each Borrower hereby represents and warrants to the
          --------                                                          
Agent and the Lenders, with respect to such Borrower's Accounts, that:  (i) each
existing Account represents, and each future Account will represent, a bona fide
                                                                       ---- ----
sale or lease and delivery of goods by the Borrower, or rendition of services by
the Borrower, in the ordinary course of the Borrower's business; (ii) each
existing Account is, and each future Account will be, for a liquidated amount
payable by the Account Debtor thereon on the terms set forth in the invoice
therefor or in the schedule thereof delivered to the Agent, without any offset,
deduction, defense, or counterclaim except those known to the Borrower and
disclosed to the Agent and the Lenders pursuant to this Agreement; (iii) no
payment will be received with respect to any Account, and no credit, discount,
or extension, or agreement therefor will be granted on any Account, except as
reported to the Agent and the Lenders in accordance with this Agreement; (iv)
each copy of an invoice delivered to the Agent by the Borrower will be a genuine
copy of the original invoice sent to the Account Debtor named therein; and (v)
all goods described in any invoice representing a sale of goods will have been
delivered to the Account Debtor and all services of the Borrower described in
each invoice will have been performed.

          (b)  No Borrower shall re-date any invoice or sale or make sales on
extended dating beyond that customary in such Borrower's business or extend or
modify any Account.  If any Borrower becomes aware of any matter adversely
affecting the collectability of any Account or Account Debtor involving an
amount greater than $100,000, including information regarding the Account
Debtor's creditworthiness, the Borrower will promptly so advise the Agent.
Agent has been advised of the terms and conditions of the Cargill Account prior
to the Closing Date.

          (c)  No Borrower shall accept any note or other instrument (except a
check or other instrument for the immediate payment of money) with respect to
any Account without the Agent's written consent, provided, that, a Borrower may
accept a note or instrument with respect to an Account without the Agent's
consent as long as all such notes and instruments accepted by the Borrowers do
not exceed $500,000 in the aggregate at any time.  If the Agent consents to the
acceptance of any such instrument, it shall be considered as evidence of the
Account and not payment thereof and the Borrower will promptly deliver such
instrument to the Agent, endorsed by the Borrower to the Agent in a manner
satisfactory in form and substance to the Agent.  Regardless of the form of

                                      -71-
<PAGE>
 
presentment, demand, notice of protest with respect thereto, the Borrower shall
remain liable thereon until such instrument is paid in full.

          (d)  Each Borrower shall notify the Agent promptly of all disputes and
claims in excess of $250,000 with any  Account Debtor, and agrees to settle,
contest, or adjust such dispute or claim at no expense to the Agent or any
Lender.  No discount, credit or allowance shall be granted to any such Account
Debtor without the Agent's prior written consent, except for discounts, credits
and allowances made or given in the ordinary course of the Borrower's business
when no Event of Default exists hereunder.  The Borrower shall send the Agent a
copy of each such credit memorandum in excess of $100,000 as soon as issued.
The Agent may, and at the direction of the Majority Lenders shall, at all times
when an Event of Default exists hereunder, settle or adjust disputes and claims
directly with Account Debtors for amounts and upon terms which the Agent or the
Majority Lenders, as applicable, shall consider advisable and, in all cases, the
Agent will credit the Borrower's Loan Account with only the net amounts received
by the Agent in payment of any Accounts.

          (e)  If an Account Debtor returns any Inventory to any Borrower when
no Event of Default exists, then the Borrower shall promptly determine the
reason for such return and shall issue a credit memorandum to the Account Debtor
in the appropriate amount. Each Borrower shall immediately report to the Agent
any return involving an amount in excess of $250,000.  Each such report shall
indicate the reasons for the returns and the locations and condition of the
returned Inventory.  In the event any Account Debtor returns Inventory to the
Borrower when an Event of Default exists, the Borrower, upon request of the
Agent, shall: (i) hold the returned Inventory in trust for the Agent; (ii)
segregate all returned Inventory from all of its other property; (iii) dispose
of the returned Inventory solely according to the Agent's written instructions;
and (iv) not issue any credits or allowances with respect thereto without the
Agent's prior written consent.  All returned Inventory shall be subject to the
Agent's Liens thereon. Whenever any Inventory is returned, the related Account
shall be deemed ineligible to the extent of the amount owing by the Account
Debtor with respect to such returned Inventory.

      6.9 Collection of Accounts; Payments.  (a) Until the Agent notifies ABT to
          --------------------------------                                      
the contrary, each Borrower shall make collection of all Accounts and other
Collateral for the Agent, shall receive 

                                      -72-
<PAGE>
 
all payments as the Agent's trustee, and shall immediately deliver all payments
in their original form duly endorsed in blank into a Payment Account established
for the account of the Borrower at a bank acceptable to Agent and subject to
documentation acceptable to Agent. If the Agent requests, each Borrower shall
establish a lock-box service for collections of Accounts at a bank acceptable to
the Agent and pursuant to documentation satisfactory to the Agent. If such lock-
box service is established, the Borrower shall instruct all Account Debtors to
make all payments directly to the address established for such service. If,
notwithstanding such instructions, the Borrower receives any proceeds of
Accounts, it shall receive such payments as the Agent's trustee, and shall
immediately deliver such payments to the Agent in their original form duly
endorsed in blank or deposit them into a Payment Account, as the Agent may
direct. All collections received in any such lock-box or Payment Account or
directly by the Borrower or the Agent, and all funds in any Payment Account or
other account to which such collections are deposited shall be subject to the
Agent's sole control. The Agent or the Agent's designee may, at any time after
the occurrence of an Event of Default, notify Account Debtors that the Accounts
have been assigned to the Agent and of the Agent's security interest therein,
and may collect them directly and charge the collection costs and expenses to
the Borrower's Loan Account as a Revolving Loan. So long as an Event of Default
has occurred and is continuing, the Borrower, at the Agent's request, shall
execute and deliver to the Agent such documents as the Agent shall require to
grant the Agent access to any post office box in which collections of Accounts
are received.

          (b) If sales of Inventory are made or services are rendered for cash,
each Borrower shall immediately deliver to the Agent or deposit into a Payment
Account the cash which the Borrower receives.

          (c)  All payments, including immediately available funds received by
the Agent at a bank designated by it, received by the Agent on account of
Accounts or as proceeds of other Collateral will be the Agent's sole property
for its benefit and the benefit of the Lenders and will be credited to the
Borrower's Loan Account (conditional upon final collection) on that Business
Day.

          (d) In the event the Borrowers repay all of the Obligations upon the
termination of this Agreement or upon acceleration of the Obligations, other
than through the Agent's receipt of payments on account of the Accounts or
proceeds of the

                                      -73-
<PAGE>
 
other Collateral, such payment will be credited (conditional upon final
collection) to the Borrowers' Loan Account on the same Business Day of the
Agent's receipt of such funds.

     6.10 Inventory; Perpetual Inventory.  Each Borrower represents and warrants
          ------------------------------                                        
to the Agent and the Lenders and agrees with the Agent and the Lenders that all
of the Inventory owned by the Borrower is and will be held for sale or lease, or
to be furnished in connection with the rendition of services, in the ordinary
course of the Borrower's business, and is and will be fit for such purposes.
The Borrower will keep its Inventory in good and marketable condition, at its
own expense.  Borrower will not, without the prior knowledge of the Agent,
acquire or accept any Inventory on consignment or approval.  The Borrower agrees
that all Inventory produced in the United States will be produced in accordance
with the Federal Fair Labor Standards Act of 1938, as amended, and all rules,
regulations, and orders thereunder.  The Borrower will conduct a physical count
of the Inventory at least once per Fiscal Year, and after and during the
continuation of an Event of Default, at such other times as the Agent requests.
The Borrower will maintain a perpetual inventory  reporting system at all times.
Except as disclosed to Agent in writing, the Borrower will not, without the
Agent's written consent, sell any Inventory on a bill-and-hold, guaranteed sale,
sale and return, sale on approval, consignment, or other repurchase or return
basis other than as provided herein.

     6.11 Equipment.  Each Borrower represents and warrants to the Agent and the
          ---------                                                             
Lenders and agrees with the Agent and the Lenders that all of the Equipment
owned by the Borrower is and will be used or held for use in the Borrower's
business, and is and will be fit for such purposes.  The Borrower shall keep and
maintain its Equipment in good operating condition and repair (ordinary wear and
tear excepted) and shall make all necessary replacements thereof.

     6.12 Assigned Contracts.  Each Borrower shall fully perform all of its
          ------------------                                               
obligations under each of the Assigned Contracts, and shall enforce all of its
rights and remedies thereunder, in each case, as it deems appropriate in its
business judgment; provided, however, that the Borrower shall not take any
                   --------  -------                                      
action or fail to take any action with respect to its Assigned Contracts which
would cause the termination of a material Assigned Contract.  Without limiting
the generality of the foregoing, the Borrower shall take all action necessary or
appropriate to permit, and shall not take any action which would have any
materially adverse effect upon, the 

                                      -74-
<PAGE>
 
full enforcement of all indemnification rights under its Assigned Contracts. The
Borrower shall not, without the Agent's and the Majority Lenders' prior written
consent, modify, amend, supplement, compromise, satisfy, release, or discharge
any of its Assigned Contracts, any collateral securing the same, any Person
liable directly or indirectly with respect thereto, or any agreement relating to
any of its Assigned Contracts or the collateral therefor. The Borrower shall
notify the Agent and the Lenders in writing, promptly after the Borrower becomes
aware thereof, of any event or fact which could give rise to a claim by any
Person for indemnification under any of its Assigned Contracts, and shall
diligently pursue such right and report to the Agent on all further developments
with respect thereto. The Borrower shall remit directly to the Agent for
application to the Obligations in such order as the Majority Lenders shall
determine, all amounts received by the Borrower as indemnification or otherwise
pursuant to its Assigned Contracts. If an Event of Default then exists, the
Agent may, and at the direction of the Majority Lenders shall, directly enforce
such right in its own or the Borrower's name and may enter into such settlements
or other agreements with respect thereto as the Agent or the Majority Lenders,
as applicable, shall determine. All such obligations of the Borrower shall be
and remain enforceable only against the Borrower and shall not be enforceable
against the Agent. Notwithstanding any provision hereof to the contrary, the
Borrower shall at all times remain liable to observe and perform all of its
duties and obligations under its Assigned Contracts, and the Agent's or any
Lender's exercise of any of their respective rights with respect to the
Collateral shall not release the Borrower from any of such duties and
obligations. Neither the Agent nor any Lender shall be obligated to perform or
fulfill any of the Borrower's duties or obligations under its Assigned Contracts
or to make any payment thereunder, or to make any inquiry as to the nature or
sufficiency of any payment or property received by it thereunder or the
sufficiency of performance by any party thereunder, or to present or file any
claim, or to take any action to collect or enforce any performance, any payment
of any amounts, or any delivery of any property.

and to proceed thereafter as herein provided.

     6.15 Power of Attorney.  Each Borrower hereby appoints the Agent and the
          -----------------                                                  
Agent's designee as the Borrower's attorney, with power:  (a)  so long as any
Event of Default has occurred and is continuing, to endorse the Borrower's name

attorney in the Borrower's name for such purpose; and (g) to do all things
necessary to carry out this Agreement.  Each Borrower ratifies and approves all
acts of such attorney.  None of the Lenders or the Agent nor their attorneys
will be liable for any acts or omissions or for any error of judgment or mistake
of fact or law.  This power, being coupled with an interest, is irrevocable
until this Agreement has been terminated and the Obligations have been fully
satisfied.

     6.16 The Agent's and Lenders' Rights, Duties and Liabilities. Each Borrower
          -------------------------------------------------------               
assumes all responsibility and liability arising from or relating to the use,
sale or other disposition of the Collateral.  The Obligations shall not be
affected by any failure of the Agent or any Lender to take any steps to perfect
the Agent's Liens or to collect or realize upon the Collateral, nor shall loss
of or damage to the Collateral release the Borrowers from any of the
Obligations.  Following the occurrence and continuation of an Event of Default,
the Agent may (but shall not be required to), and at the direction of the
Majority Lenders shall, without notice to or consent from the Borrowers, sue
upon or otherwise collect, extend the time for payment of, modify or amend the
terms of, compromise or settle for cash, credit, or otherwise upon any terms,
grant other indulgences, extensions, renewals, compositions, or releases, and
take or omit to take any other action with respect to the Collateral, any
security therefor, any agreement relating thereto, any insurance applicable
thereto, or any Person liable directly or indirectly in connection with any of
the foregoing, without discharging or otherwise affecting the liability of the
Borrowers for the Obligations or under this Agreement or any other agreement now
or hereafter existing between the Agent and/or any Lender and the Borrowers.

shall cause each of its Subsidiaries to maintain, flood insurance, in the event
of a designation of any of the Equipment and Inventory located on such Real
Estate is located as "flood prone" or a "flood risk area," (hereinafter "SFHA")
as defined by the Flood Disaster Protection Act of 1973, in an amount to be
reasonably determined by the Agent, and shall comply with the additional
requirements of the National Flood Insurance Program as set forth in said Act.
The Borrower shall also maintain flood insurance for its Inventory which is, at
any time, located in a SFHA.

          (b)  The Borrower shall cause the Agent, for the ratable benefit of
the Agent and the Lenders, to be named in each such policy covering the
Collateral as secured party and sole loss payee 

                                      -93-

or additional insured, in a manner reasonably acceptable to the Agent. Each
policy of insurance shall contain a clause or endorsement requiring the insurer
to give not less than thirty (30) days' prior written notice to the Agent in the
event of cancellation of the policy for any reason whatsoever and a clause or
endorsement stating that the interest of the Agent shall not be impaired or
invalidated by any act or neglect of the Borrower or any of its Subsidiaries or
the owner of any premises for purposes more hazardous than are permitted by such
policy. All premiums for such insurance shall be paid by the Borrower when due,
and certificates of insurance and, if requested by the Agent, photocopies of the
policies, shall be delivered to the Agent, in each case in sufficient quantity
for distribution by the Agent to each of the Lenders. If the Borrower fails to
procure such insurance or to pay the premiums therefor when due, the Agent may,
after reasonable notice to ABT, and at the direction of the Majority Lenders
shall, do so from the proceeds of Revolving Loans.

          (c)  The Borrower shall promptly notify the Agent and the Lenders of
any loss, damage, or destruction to Collateral having a value in excess of
$250,000, arising from its use, whether or not covered by insurance.  Prior to
the occurrence of an Event of Default, ABT shall be authorized to collect all
insurance proceeds and shall use such proceeds to repair or replace the
Collateral. After an Event of Default, the Agent is hereby authorized to collect
all insurance proceeds directly, and to apply or remit them as follows:

               (i)  With respect to insurance proceeds relating to property
other than Collateral, after deducting from such proceeds the reasonable
expenses, if any, incurred by the Agent in the collection or handling thereof,
the Agent shall promptly remit to the Borrower such proceeds.

               (ii) With respect to insurance proceeds relating to Collateral
other than Fixed Assets, after deducting from such proceeds the reasonable
expenses, if any, incurred by the Agent in the collection or handling thereof,
the Agent shall apply such proceeds, ratably, to the reduction of the
Obligations in the order provided for in Section 4.8.

Environmental Laws applicable to it, including, without limitation, those
relating to the generation, handling, use, storage, and disposal of any

shall submit to the Agent and the Lenders annually, commencing on the first
Anniversary Date, and on each Anniversary Date thereafter, an update of the
status of each environmental compliance or liability issue.  The Agent or any
Lender may request copies of technical reports prepared by the Borrower and its

may, in its discretion, and shall, at the direction of the Majority Lenders, do
one or more of the following 

                                     -106-
<PAGE>
 
at any time or times and in any order, without notice to or demand on any
Borrower: (i) reduce the Maximum Revolver Amount, or the advance rates against
Eligible Accounts and/or Eligible Inventory used in computing the Availability,
or reduce one or more of the other elements used in computing the Availability;
(ii) restrict the amount of or refuse to make Revolving Loans; and (iii)
restrict or refuse to arrange for or provide Letters of Credit or Credit
Support. If an Event of Default exists, the Agent shall, at the direction of the
Majority Lenders, do one or more of the following, in addition to the actions
described in the preceding sentence, at any time or times and in any order,
without notice to or demand on any Borrower or Canadian Guarantor: (a) terminate
the Commitments and this Agreement; (b) declare any or all Obligations to be
immediately due and payable; provided, however, that upon the occurrence of any 
                             --------  -------           
Event of Default described in Sections 11.1(f), 11.1(g), 11.1(h), or 11.1(i),
                              ----------------  -------  -------     ------- 
the Commitments shall automatically and immediately expire and all Obligations
shall automatically become immediately due and payable without notice or demand
of any kind; and (c) pursue its other rights and remedies under the Loan
Documents and applicable law.

          (b)  If an Event of Default has occurred and is continuing:  (i) the
Agent shall have for the benefit of the Lenders, in addition to all other rights
of the Agent and the Lenders, the rights and remedies of a secured party under
the UCC; (ii) the Agent may, at any time, take possession of the Collateral and
keep it on any Borrower's or Canadian Guarantor's premises, at no cost to the
Agent or any Lender, or remove any part of it to such other place or places as
the Agent may desire, or each Borrower or Canadian Guarantor shall, upon the
Agent's demand, at the Borrower's or Canadian Guarantor's cost, assemble the
Collateral and make it available to the Agent at a place reasonably convenient
to the Agent; and (iii) the Agent may sell and deliver any Collateral at public
or private sales, for cash, upon credit or otherwise, at such prices and upon
such terms as the Agent deems advisable, in its sole discretion, and may, if the
Agent deems it reasonable, postpone or adjourn any sale of the Collateral by an
announcement at the time and place of sale or of such postponed or adjourned
sale without giving a new notice of sale.  Without in any way requiring notice
to be given in the following manner, each Borrower and Canadian Guarantor agrees
that any notice by the Agent of sale, disposition or other intended action
hereunder or in connection herewith, whether required by the UCC or otherwise,
shall constitute reasonable notice to such Borrower if such notice is mailed by
registered or certified mail, return receipt 

                                     -107-
<PAGE>
 
requested, postage prepaid, or is delivered personally against receipt, at least
five (5) Business Days prior to such action to the Borrower's address specified
in or pursuant to Section 15.8. If any Collateral is sold on terms other than 
                  ------------ 
payment in full at the time of sale, no credit shall be given against the
Obligations until the Agent or the Lenders receive payment, and if the buyer
defaults in payment, the Agent may resell the Collateral without further notice
to any Borrower or Canadian Guarantor. In the event the Agent seeks to take
possession of all or any portion of the Collateral by judicial process, each
Borrower irrevocably waives: (a) the posting of any bond, surety or security
with respect thereto which might otherwise be required; (b) any demand for
possession prior to the commencement of any suit or action to recover the
Collateral; and (c) any requirement that the Agent retain possession and not
dispose of any Collateral until after trial or final judgment. Each Borrower
agrees that the Agent has no obligation to preserve rights to the Collateral or
marshal any Collateral for the benefit of any Person. The Agent is hereby
granted a license, without charge, and has the right to use such license in
connection with, following the occurrence of an Event of Default that is
continuing, each Borrower's labels, patents, copyrights, name, trade secrets,
trade names, trademarks, and advertising matter, or any similar property, in
completing production of, advertising or selling any Collateral, and each
Borrower's rights under all licenses and all franchise agreements shall inure to
the Agent's benefit for such purpose. The proceeds of sale shall be applied
first to all expenses of sale, including attorneys' fees, and then to the
Obligations in accordance with Section 4.8. The Agent will return any excess 
                               -----------  
to the Borrowers and the Borrowers shall remain jointly and severally liable for
any deficiency .

           (c)  If an Event of Default occurs, each Borrower hereby waives all
rights to notice and hearing prior to the exercise by the Agent of the Agent's
rights to repossess the Collateral without judicial process or to replevy,
attach or levy upon the Collateral without notice or hearing.

then outstanding. Notwithstanding the termination of this Agreement, until all

shall remain bound by the terms of this Agreement and shall not be relieved of

their rights and remedies hereunder (including, without limitation, the Agent's
Liens in and all rights and remedies with respect to all then existing and 
after-arising Collateral).

          (a)  Any Lender may, with the written consent of the Agent which
consent is not to be unreasonably withheld, assign and delegate to one or more

such Lender) (each an "Assignee") all, or any ratable part of all, of the Loans,

such Lender's Commitment; provided, however, that the Borrowers and the Agent
                          --------  -------
may continue to deal solely and directly with such Lender in connection with the
interest so assigned to an Assignee until (i) written notice of such assignment,
together with payment instructions, addresses and related information with
respect to the Assignee, shall have been given to the Borrowers and the Agent by
such Lender and the Assignee; (ii) such Lender and its Assignee shall have
delivered to the Borrowers and the Agent an Assignment and Acceptance in the
form of Exhibit "G" ("Assignment and Acceptance") [together with any Note or
        -----------   -------------------------                             
Notes subject to such assignment] and (iii) the assignor Lender or Assignee has
paid to the Agent a processing fee in the amount of $3,000.

          (b) From and after the date that the Agent notifies the assignor
Lender that it has received an executed Assignment and Acceptance and payment of
the above-referenced processing fee, (i) the Assignee thereunder shall be a
party hereto and, to the extent that rights and obligations, including, but not
limited to, the obligation to participate in Letters of Credit and Credit
Support have been assigned to it pursuant to such Assignment and Acceptance,
shall have the rights and obligations of a Lender under the Loan Documents, and
(ii) the assignor Lender shall, to the extent that rights and obligations
hereunder and under the other Loan Documents have been assigned by it pursuant
to such Assignment and Acceptance, relinquish its rights and be released from
its obligations under this Agreement (and in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

          (c)  By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the Assignee thereunder confirm to and agree
with each other and the other parties hereto as follows:  (1) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other Loan Document furnished
pursuant hereto; (2) such assigning Lender makes no representation or warranty
and assumes no responsibility with respect to the financial condition of any
Borrower or the performance or observance by any Borrower of 

                                     -111-
<PAGE>
 
any of its obligations under this Agreement or any other Loan Document furnished
pursuant hereto; (3) such Assignee confirms that it has received a copy of this
Agreement, together with such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (4) such Assignee will, independently and without
reliance upon the Agent, such assigning Lender 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 under
this Agreement; (5) such Assignee appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
as are delegated to the Agent by the terms hereof, together with such powers as
are reasonably incidental thereto; and (6) such Assignee agrees that it will
perform in accordance with their terms all of the obligations which by the terms
of this Agreement are required to be performed by it as a Lender.

          (d) Within five Business Days after its receipt of notice by the Agent
that it has received an executed Assignment and Acceptance and payment of the
processing fee, the Borrowers shall execute and deliver to the Agent, new Notes
evidencing such Assignee's assigned Loans and, if the assignor Lender has
retained a portion of its Loans and its Commitment, replacement Notes in the
principal amount of the Loans retained by the assignor Lender (such Notes to be
in exchange for, but not in payment of, the Notes held by such Lender).
Immediately upon each Assignee's making its processing fee payment under the
Assignment and Acceptance, this Agreement shall be deemed to be amended to the
extent, but only to the extent, necessary to reflect the addition of the
Assignee and the resulting adjustment of the Commitments arising therefrom. The

Lender and the other interests of that Lender (the "originating Lender")

of such obligations, (iii) the Borrowers and the Agent shall continue to deal
solely and directly with the originating Lender in connection with the

Lender's rights and obligations under this Agreement and the other Loan
Documents, and (iv) no Lender shall transfer or grant any participating interest
under which the Participant has rights to approve any amendment to, or any
consent or waiver with respect to, this Agreement or any other Loan Document,
and all amounts payable by the Borrowers hereunder shall be determined as if
such Lender had not sold such participation; except that, if amounts outstanding
under this Agreement are due and unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of set-off in respect of its
participating interest in amounts owing under this Agreement to the same extent
and subject to the same limitation as if the amount of its participating
interest were owing directly to it as a Lender under this Agreement.

          (f)  Notwithstanding any other provision in this Agreement, any Lender
may at any time create a security interest in, or pledge, all or any portion of
its rights under and interest in this Agreement in favor of any Federal Reserve
Bank in accordance with Regulation A of the FRB or U.S. Treasury Regulation 31
CFR (S)203.14, and such Federal Reserve Bank may enforce such pledge or security
interest in any manner permitted under applicable law.

new Subsidiaries.  Upon ABT's request, and subject to Agent's full satisfaction
with the assets, the books and records, and the financial and business
conditions of the newly created or acquired Subsidiary following Agent's
appraisal and evaluation thereof, the new Subsidiary may, by executing a

Agreement, become a Borrower under this Agreement and shall thereafter have the
rights and obligations of a Borrower under this Agreement and under the Loan
Documents effective as of the date set forth in the Joinder Agreement.

                                   THE AGENT
                                   ---------

      14.1 Appointment and Authorization.  Each Lender hereby designates and
           -----------------------------                                    
appoints BankAmerica Business Credit, Inc. as its Agent under this Agreement and
the other Loan Documents and each Lender hereby irrevocably authorizes the Agent
to take such action on its behalf under the provisions of this Agreement and
each other Loan Document and to exercise such powers and perform such duties as
are expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.  The
Agent agrees to act as such on the express conditions contained in this Article
                                                                        -------
14.  The provisions of this Article 14 are solely for the benefit of the Agent
- --                          ----------                                        
and the Lenders and the Borrowers shall have no rights as a third party
beneficiary of any of the provisions contained herein. Notwithstanding any
provision to the contrary contained elsewhere in this Agreement or in any other
Loan Document, the Agent shall not have any duties or responsibilities, except
those expressly set forth herein, nor shall the Agent have or be deemed to have
any fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.
Without limiting the generality of the foregoing sentence, the use of the term
"agent" in this Agreement with reference to the Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law.  Instead, such term is used merely as a matter
of market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties.  Except as expressly
otherwise provided in this Agreement, the Agent shall have and may use its sole
discretion with respect to exercising or refraining from exercising any
discretionary rights or taking or refraining from taking any actions which the
Agent is expressly entitled to take or assert under this Agreement and the other
Loan Documents, including, without limitation, (a) the determination of the
applicability of ineligibility criteria with respect to the calculation of the
Availability, (b) the making of Agent Advances pursuant to Section 2.2(i), and
                                                           --------------     
(c) the exercise of remedies pursuant to Section 11.2, and any action so taken
                                         ------------                         
or not taken shall be deemed consented to by the Lenders.

<PAGE>
 
      14.2 Delegation of Duties.  The Agent may execute any of its duties under
           --------------------                                                
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.  The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects as
long as such selection was made without gross negligence or willful misconduct.

      14.3 Liability of Agent.  None of the Agent-Related Persons shall (i) be
           ------------------                                                 
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Lenders for any recital,
statement, representation or warranty made by any Borrower or any Subsidiary or
Affiliate of any Borrower, or any officer thereof, contained in this Agreement
or in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of any Borrower or any other party
to any Loan Document to perform its obligations hereunder or thereunder.  No
Agent-Related Person shall be under any obligation to any Lender to ascertain or
to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the properties, books or records of any Borrower or any of such
Borrower's Subsidiaries or Affiliates.

      14.4 Reliance by Agent.  (a)  The Agent shall be entitled to rely, and
           -----------------                                                
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to the Borrowers), independent accountants and other experts selected by the
Agent. The Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Majority Lenders as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and 

                                     -115-
<PAGE>
 
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Agent shall in all cases be fully protected in acting, or
in refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Majority Lenders and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all of the Lenders.

          (b) For purposes of determining compliance with the conditions
specified in Section 10.1, each Lender that has executed this Agreement shall be
             ------------                                                       
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Lender.

     14.5 Notice of Default.  The Agent shall not be deemed to have knowledge or
          -----------------                                                     
notice of the occurrence of any Default or Event of Default, except with respect
to defaults in the payment of principal, interest and fees required to be paid
to the Agent for the account of the Lenders, unless the Agent shall have
received written notice from a Lender or a Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default."  The Agent will notify the Lenders of its receipt of any
such notice.  The Agent shall take such action with respect to such Default or
Event of Default as may be requested by the Majority Lenders in accordance with
Section 11; provided, however, that unless and until the Agent has received any
- ----------  --------  -------                                                  
such request, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable.

     14.6 Credit Decision.  Each Lender acknowledges that none of the Agent-
          ---------------                                                  
Related Persons has made any representation or warranty to it, and that no act
by the Agent hereinafter taken, including any review of the affairs of the
Borrowers and their Affiliates, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Lender.  Each Lender represents
to the Agent that it has, independently and without reliance upon any Agent-
Related Person and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrowers and their Affiliates, and all applicable bank
regulatory laws 

                                     -116-
<PAGE>
 
relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to the Borrower. Each Lender also
represents that it will, independently and without reliance upon any Agent-
Related Person and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigations as it deems necessary to inform
itself as to the business, prospects, operations, property, financial and other
condition and creditworthiness of the Borrower. Agent will provide to each
Lender (a) any reports or other information which Borrower delivers to Agent in
duplicate for distribution to Lenders, and (b) any other information delivered
by Borrower to Agent but only if a Lender makes a reasonable request therefor.
Except for notices, reports and other documents expressly herein required to be
furnished to the Lenders by the Agent, the Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of the Borrowers which may come into the
possession of any of the Agent-Related Persons.

     14.7 Indemnification.  Whether or not the transactions contemplated hereby
          ---------------                                                      
are consummated, the Lenders shall indemnify upon demand the Agent-Related
Persons (to the extent not reimbursed by or on behalf of the Borrowers and
without limiting the obligation of the Borrowers to do so), pro rata, from and
                                                            --- ----          
against any and all Indemnified Liabilities as such term is defined in Section
                                                                       -------
15.11; provided, however, that no Lender shall be liable for the payment to the
- -----  --------  -------                                                       
Agent-Related Persons of any portion of such Indemnified Liabilities resulting
solely from such Person's gross negligence or willful misconduct.  Without
limitation of the foregoing, each Lender shall reimburse the Agent upon demand
for its ratable share of any costs or out-of-pocket expenses (including Attorney
Costs) incurred by the 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, any other Loan
Document, or any document contemplated by or referred to herein, to the extent
that the Agent is not reimbursed for such expenses by or on behalf of the
Borrowers.  The undertaking in this Section shall survive the payment of all
Obligations hereunder and the resignation or replacement of the Agent.

     14.8 Agent in Individual Capacity.  BABC and its Affiliates may make loans
          ----------------------------                                         
to, issue letters of credit for the account of, accept deposits from, acquire
equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Borrowers and their
Subsidiaries and Affiliates as though BABC were not the Agent hereunder and
without notice to or consent of the Lenders.  The Lenders acknowledge that,
pursuant to such activities, BABC or its Affiliates may receive information
regarding the Borrowers or their Affiliates (including information that may be
subject to confidentiality obligations in favor of the Borrowers or such
Subsidiaries) and acknowledge that the Agent shall be under no obligation to
provide such information to them.  With respect to its Loans, BABC shall have
the same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not the Agent, and the terms "Lender" and
"Lenders" include BABC in its individual capacity.

     14.9 Successor Agent.  The Agent may resign as Agent upon 30 days' notice
          ---------------                                                     
to the Lenders and the Borrowers.  In the event BABC sells all of its
Commitments and Revolving Loans as part of a sale, transfer or other disposition
by BABC of substantially all of its loan portfolio, BABC shall resign as Agent
and such purchaser or transferee shall become the successor Agent hereunder.  If
the Agent resigns under this Agreement, subject to the provision in the
preceding sentence, the Majority Lenders shall appoint from among the Lenders a
successor agent for the Lenders.  If no successor agent is appointed prior to
the effective date of the resignation of the Agent, the Agent may appoint, after
consulting with the Lenders and the Borrowers, a successor agent from among the
Lenders.  Upon the acceptance of its appointment as successor agent hereunder,
such successor agent shall succeed to all the rights, powers and duties of the
retiring Agent and the term "Agent" shall mean such successor agent and the
retiring Agent's appointment, powers and duties as Agent shall be terminated.
After any retiring Agent's resignation hereunder as Agent, the provisions of
this Section 14 shall inure to its benefit as to any actions taken or omitted to
     ----------                                                                 
be taken by it while it was Agent under this Agreement. If no successor agent
has accepted appointment as Agent by the date which is 30 days following a
retiring Agent's notice of resignation, the retiring Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the
duties of the Agent hereunder until such time, if any, as the Majority Lenders
appoint a successor agent as provided for above. In the event BABC, or its
Affiliates, do not have a Commitment 

                                     -118-
<PAGE>
 
equal to at least fifty percent (50%) of the Commitments and an Event of Default
does not then exist, the Borrower may request that one of the other Lenders be
designated as the agent in lieu of BABC and if the Lender is willing to serve as
agent BABC will then resign as agent.

    14.10 Withholding Tax.  (a)  If any Lender is a "foreign corporation,
          ---------------                                                
partnership or trust" within the meaning of the Code and such Lender claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or
1442 of the Code, such Lender agrees with and in favor of the Agent, to deliver
to the Agent:

               (i) if such Lender claims an exemption from, or a reduction of,
withholding tax under a United States tax treaty, properly completed IRS Forms
1001 and W-8 before the payment of any interest in the first calendar year and
before the payment of any interest in each third succeeding calendar year during
which interest may be paid under this Agreement;

               (ii) if such Lender claims that interest paid under this
Agreement is exempt from United States withholding tax because it is effectively
connected with a United States trade or business of such Lender, two properly
completed and executed copies of IRS Form 4224 before the payment of any
interest is due in the first taxable year of such Lender and in each succeeding
taxable year of such Lender during which interest may be paid under this
Agreement, and IRS Form W-9; and

               (iii) such other form or forms as may be required under the Code
or other laws of the United States as a condition to exemption from, or
reduction of, United States withholding tax.

Such Lender agrees to promptly notify the Agent of any change in circumstances
which would modify or render invalid any claimed exemption or reduction.

          (b)  If any Lender claims exemption from, or reduction of, withholding
tax under a United States tax treaty by providing IRS Form 1001 and such Lender
sells, assigns, grants a participation in, or otherwise transfers all or part of
the Obligations of the Borrowers to such Lender, such Lender agrees to notify
the Agent of the percentage amount in which it is no longer the beneficial owner
of Obligations of the Borrowers to such 

                                     -119-
<PAGE>
 
Lender. To the extent of such percentage amount, the Agent will treat such
Lender's IRS Form 1001 as no longer valid.

          (c)  If any Lender claiming exemption from United States withholding
tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Borrower to such Lender, such Lender agrees to undertake sole responsibility for
complying with the withholding tax requirements imposed by Sections 1441 and
1442 of the Code.

          (d) If any Lender is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Lender
an amount equivalent to the applicable withholding tax after taking into account
such reduction.  If the forms or other documentation required by subsection (a)
of this Section are not delivered to the Agent, then the Agent may withhold from
any interest payment to such Lender not providing such forms or other
documentation an amount equivalent to the applicable withholding tax.

          (e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Agent did not properly
withhold tax from amounts paid to or for the account of any Lender (because the
appropriate form was not delivered, was not properly executed, or because such
Lender failed to notify the Agent of a change in circumstances which rendered
the exemption from, or reduction of, withholding tax ineffective, or for any
other reason) such Lender shall indemnify the Agent fully for all amounts paid,
directly or indirectly, by the Agent as tax or otherwise, including penalties
and interest, and including any taxes imposed by any jurisdiction on the amounts
payable to the Agent under this Section, together with all costs and expenses
(including Attorney Costs).  The obligation of the Lenders under this subsection
shall survive the payment of all Obligations and the resignation or replacement
of the Agent.

    14.11 Collateral Matters.
          ------------------ 

          (a)  The Lenders hereby irrevocably authorize the Agent, at its option
and in its sole discretion, to release any Agent's Lien upon any Collateral (i)
upon the termination of the Commitments and payment and satisfaction in full by
Borrowers of all Loans and reimbursement obligations in respect of Letters of
Credit and Credit Support, and the termination of all outstanding 

                                     -120-
<PAGE>
 
Letters of Credit (whether or not any of such obligations are due) and all other
Obligations; (ii) constituting property being sold or disposed of if the selling
Borrower certifies to the Agent that the sale or disposition is made in
compliance with Section 9.9 (and the Agent may rely conclusively on any such
                -----------                                                 
certificate, without further inquiry); (iii) constituting property in which the
Borrower owned no interest at the time the Lien was granted or at any time
thereafter; or (iv) constituting property leased to the Borrower under a lease
which has expired or been terminated in a transaction permitted under this
Agreement.  Except as provided above, the Agent will not release any of the
Agent's Liens without the prior written authorization of the Lenders; provided
                                                                      --------
that the Agent may, in its discretion, release the Agent's Liens (i) on
Collateral valued in the aggregate not in excess of $1,000,000 during any one
year period, and (ii) in the Proprietary Rights as provided in Section 9.23 and
                                                               ------------    
9.24; in each instance without the prior written authorization of the Lenders.
- ----                                                                           
Upon request by the Agent or any Borrower at any time, the Lenders will confirm
in writing the Agent's authority to release any Agent's Liens upon particular
types or items of Collateral pursuant to this Section 14.11.
                                              ------------- 

          (b)  Upon receipt by the Agent of any authorization required pursuant
to Section 14.11(a) from the Lenders of the Agent's authority to release any
   ----------------                                                         
Agent's Liens upon particular types or items of Collateral, and upon at least
five (5) Business Days' prior written request by any Borrower,  the Agent shall
(and is hereby irrevocably authorized by the Lenders to) execute such documents
as may be necessary to evidence the release of the Agent's Liens upon such
Collateral; provided, however, that (i) the Agent shall not be required to
            --------  -------                                             
execute any such document on terms which, in the Agent's opinion, would expose
the Agent to liability or create any obligation or entail any consequence other
than the release of such Liens without recourse or warranty, and (ii) such
release shall not in any manner discharge, affect or impair the Obligations or
any Liens (other than those expressly being released) upon (or obligations of
the Borrowers in respect of) all interests retained by the Borrower, including
(without limitation) the proceeds of any sale, all of which shall continue to
constitute part of the Collateral.

          (c)  The Agent shall have no obligation whatsoever to any of the
Lenders to assure that the Collateral exists or is owned by any Borrower or is
cared for, protected or insured or has been encumbered, or that the Agent's

intended by the Borrowers, the Canadian Guarantors, the Agent and the Lenders to
be the final, complete, and exclusive expression of the agreement between them.
This Agreement supersedes any and all prior oral or written agreements relating
to the subject matter hereof.  No modification, rescission, waiver, release, or
amendment of any provision of this Agreement or any other Loan Document shall be
made, except by a written agreement signed by the Borrowers and a duly
authorized officer of each of the Agent and the requisite Lenders.

counterparts, and by the Agent, each Lender and each Borrower in separate
counterparts, each of which shall be an original, but all of which shall
together constitute one and the same agreement; signature pages may be detached
from multiple separate counterparts and attached to a single counterpart so that
all signature pages are physically attached to the same document.

convenience of reference only, are without substantive meaning and should not be
construed to modify, enlarge, or restrict any provision.

      15.16 Right of Setoff.  In addition to any rights and remedies of the
            ---------------                                                
Lenders provided by law, if an Event of Default exists or the Loans have been
accelerated, each Lender is authorized at any time and from time to time,
without prior notice to any Borrower, any such notice being waived by each
Borrower to the fullest extent permitted by law, to set off and apply any and
all deposits (general or special, time or demand, provisional or final) at any
time held by, and other indebtedness at any time owing by, such Lender to or for
the credit or the account of any Borrower against any and all Obligations owing
to such Lender, now or hereafter existing, irrespective of whether or not the
Agent or such Lender shall have made demand under this Agreement or any Loan
Document and although such Obligations may be contingent or unmatured.  Each
Lender agrees promptly to notify the Borrowers and the Agent after any such set-
off and application made by such Lender; provided, however, that the failure to
                                         --------  -------                     
give such notice shall not affect the validity of such set-off and application.
NOTWITHSTANDING THE FOREGOING, NO LENDER SHALL EXERCISE ANY RIGHT OF SET-OFF,
BANKER'S LIEN, OR THE LIKE AGAINST ANY DEPOSIT ACCOUNT OR PROPERTY OF THE
BORROWERS HELD OR MAINTAINED BY SUCH LENDER WITHOUT THE PRIOR WRITTEN UNANIMOUS
CONSENT OF THE LENDERS.

      15.17 Joint and Several Liability.  The Borrowers shall be liable for all
            ---------------------------                                        
amounts due to the Agent and/or any Lender under this Agreement, regardless of
which Borrower actually receives Loans or other extensions of credit hereunder
or the amount of such Loans received or the manner in which the Agent and/or
such Lender accounts for such Loans or other extensions of credit on its books
and records. Each Borrower's Obligations with respect to Loans made to it, and
each Borrower's Obligations arising as a result of the joint and several
liability of the Borrowers hereunder, with respect to Loans made to the other
Borrowers hereunder, shall be 

                                     -132-
<PAGE>
 
separate and distinct obligations, but all such Obligations shall be primary
obligations of each Borrower.

          Each Borrower's Obligations arising as a result of the joint and
several liability of the Borrower hereunder with respect to Loans or other
extensions of credit made to the other Borrowers hereunder shall, to the fullest
extent permitted by law, be unconditional irrespective of (i) the validity or
enforceability, avoidance or subordination of the Obligations of the other
Borrowers or of any promissory note or other document evidencing all or any part
of the Obligations of the other Borrowers, (ii) the absence of any attempt to
collect the Obligations from the other Borrowers, any other guarantor, or any
other security therefor, or the absence of any other action to enforce the same,
(iii) the waiver, consent, extension, forbearance or granting of any indulgence
by the Agent and/or any Lender with respect to any provision of any instrument
evidencing the Obligations of the other Borrowers, or any part thereof, or any
other agreement now or hereafter executed by the other Borrowers and delivered
to the Agent and/or any Lender, (iv) the failure by the Agent and/or any Lender
to take any steps to perfect and maintain its security interest in, or to
preserve its rights to, any security or collateral for the Obligations of the
other Borrowers, (v) the Agent's and/or any Lender's election, in any proceeding
instituted under the Bankruptcy Code, of the application of Section 1111(b)(2)
of the Bankruptcy Code, (vi) any borrowing or grant of a security interest by
the other Borrowers, as debtors-in-possession under Section 364 of the
Bankruptcy Code, (vii) the disallowance of all or any portion of the Agent's
and/or any Lender's claim(s) for the repayment of the Obligations of the other
Borrowers under Section 502 of the Bankruptcy Code, or (viii) any other
circumstances which might constitute a legal or equitable discharge or defense
of a guarantor or of the other Borrowers.  With respect to each Borrower's
Obligations arising as a result of the joint and several liability of the
Borrowers hereunder with respect to Loans or other extensions of credit made to
any of the other Borrower hereunder, each Borrower waives, until the Obligations
shall have been paid in full and the Loan Agreement shall have been terminated,
any right to enforce any right of subrogation or any remedy which the Agent
and/or any Lender now has or may hereafter have against such Borrower, any
endorser or any guarantor of all or any part of the Obligations, and any benefit
of, and any right to participate in, any security or collateral given to the
Agent and/or any Lender to secure payment of the Obligations or any other
liability of the Borrowers to the Agent and/or any Lender.

                                     -133-

          Upon any Event of Default, the Agent may proceed directly and at once,
without notice, against any Borrower to collect and recover the full amount, or
any portion of the Obligations, without first proceeding against any other
Borrower or any other Person, or against any security or collateral for the
Obligations.  Each Borrower consents and agrees that the Agent shall be under no
obligation to marshal any assets in favor of such Borrower or against or in
payment of any or all of the Obligations.

    15.18 Contribution and Indemnification among the Borrowers. Each Borrower is
          ----------------------------------------------------                  
obligated to repay the Obligations as joint and several obligors under this
Agreement.  To the extent that any Borrower shall, under this Agreement as a
joint and several obligor, repay any of the Obligations constituting Loans made
to another Borrower hereunder or other Obligations incurred directly and
primarily by any other Borrower (an "Accommodation Payment"), then the Borrower
making such Accommodation Payment shall be entitled to contribution and
indemnification from, and be reimbursed by, each of the other Borrowers in an
amount, for each of such other Borrowers, equal to a fraction of such
Accommodation Payment, the numerator of which fraction is such other Borrower's
"Allocable Amount" (as defined below) and the denominator of which is the sum of
the Allocable Amounts of all of the Borrowers.  As of any date of determination,
the "Allocable Amount" of each Borrower shall be equal to the maximum amount of
liability for Accommodation Payments which could be asserted against such
Borrower hereunder without (i) rendering such Borrower "insolvent" within the
meaning of Section 101(31) of the Bankruptcy Code, Section 2 of the Uniform
Fraudulent Transfer Act (the "UFTA"), or Section 2 of the Uniform Fraudulent
Conveyance Act (the "UFCA"), (ii) leaving such Borrower with unreasonably small
capital or assets, within the meaning of Section 548 of the Bankruptcy Code,
Section 4 of the UFTA, or Section 5 of the UFCA, or (iii) leaving such Borrower
unable to pay its debts as they become due within the meaning of Section 548 of
the Bankruptcy Code or Section 4 of the UFTA, or Section 5 of the UFCA.  All
rights and claims of contribution, indemnification and reimbursement under this
Section shall be subordinate in right of payment to the prior payment in full of
the Obligations.  The provisions of this Section shall, to the extent expressly
inconsistent with any provision in any Loan Document, supersede such
inconsistent provision.

    15.19 Agency of ABT for each other Borrower.  Each of the other Borrowers
          -------------------------------------                              
appoints ABT as its agent for all purposes relevant to this Agreement, including
(without limitation) the giving and 

                                     -134-
<PAGE>
 
receipt of notices and the execution and delivery of all documents, instruments
and certificates contemplated herein and all modifications hereto. Any
acknowledgment, consent, direction, certification or other action which might
otherwise be valid or effective only if given or taken by all of the Borrowers
acting singly, shall be valid and effective if given or taken only by ABT,
whether or not any of the other Borrowers joins therein.
