     -----

     (a)  In addition to the Base Salary, Employee will be entitled to an annual

     -------

     (a)  Employee shall receive options (the "Bonus Options") issued under the
          Eltrax Stock Incentive Plans (the "Option Plans") to acquire 500,000
          shares of Eltrax common stock (the "Bonus Stock") at an exercise
          price equal to the market price of such Bonus Stock on the Employment
          Date. To the extent permitted under applicable law the Bonus Options
          shall be characterized as incentive stock options under Section 422 of
          the Internal Revenue Code of 1986, as amended (the "Code").

          (i)  The Bonus Options shall vest, subject to Article 3, according
               to the following schedule: (A) 100,000 on the Employment
               Date, and (B) 100,000 on each successive yearly anniversary
               of the Employment Date.

          (ii) Provided termination of this Agreement has not occurred pursuant
               to Sections 3.1(a) or 3.2(a), the Company guarantees that at
               March 31, 2003, or if earlier, the end of the Severance Period
               (as defined in Section 3.2(b)(ii)), the difference between the
               Bonus Stock Fair Market Value (defined below) and the aggregate
               exercise price of Employee's vested Bonus Options will be no less
               than $1,305,000. In the event such difference is less than
               $1,305,000, the Company will pay to the Employee the amount of
               such deficiency (but in no event more than $1,305,000) as
               additional compensation, as soon as practicable following the
               calculation of such deficiency. Bonus Stock Fair Market Value
               shall mean the average of the closing prices of Eltrax common
               stock on each of the

               five trading days preceding the day immediately prior to
               March 31, 2003, or if earlier, the end of the Severance Period,
               multiplied by the number of shares of Bonus Stock which may be
               acquired pursuant to exercise of Employee's vested Bonus Options.

     (b)  During the first quarter of each year beginning in 2000, Employee
          shall receive options to acquire a minimum of 50,000 shares of
          Eltrax's common stock at the market price of such shares on such
          issuance date (the "Performance Options"). To the extent permitted
          under applicable law, the Performance Options shall be characterized
          as incentive stock options under Section 422 of the Code. The vesting
          of such Performance Options shall be based on standards of performance
          for the Employee and the Company determined by the Company's Board of
          Directors; provided, however, that vesting shall not be delayed beyond
          March 31, 2003.

     (c)  All aspects of the Bonus Options and the Performance Options shall be
          governed by the terms and conditions of the Eltrax Option Plans,
          unless specific language regarding the treatment of such Options
          appears in this Agreement.

     --------
     participate in all benefit plans currently maintained or hereafter
     established by the Company for the benefit of its executive officers
     generally, in accordance with the terms and conditions of such plans (each
     a "Benefit Plan"). To the extent Employee is subject to any waiting period
     pending entry into a particular Benefit Plan, the Company will reimburse
     Employee during such period for his actual COBRA costs, if any, under his
     prior employer's group health plan.

2.5  Vacation. Employee shall be entitled to twenty-five (25) paid vacation days
     --------
     for each twelve (12) month period of employment, which if unused, shall
     accrue ratably during each such period.

     --------
     and necessarily incurred by Employee during the course and in furtherance
     of his employment, subject to and made in accordance with such reasonable
     and nondiscriminatory policies and procedures as may be established by the
     Company as applicable to its employees.

                     the Bonus applicable to the subsequent calendar year,
                     calculated by multiplying the Bonus for such year by a

each Lender, severally and not jointly, will make Revolving Advances to

any time no to exceed such Lender's Commitment Percentage of the lesser of (x)

          (i) up to 85%, subject to the provisions of Section 2.1(b) hereof
     ("Advance Rate"), of the Net Amount of Eligible Receivables, plus
                                                                  ----

<PAGE>

          (iii) the aggregate amount of Letters of Credit outstanding, minus
                                                                       -----

          (iv) such reserves as Agent may reasonably deem proper and necessary
     from time to time after giving Borrowing Agent five (5) Business Days prior
     written notice of the imposition of such reserves.

     The amount derived from the sum of Sections 2.1(a)(y)(i)  and (ii) minus
                                                                        -----
Sections 2.1 (a)(y)(iii) and (iv) at any time and from time to time shall be
referred to as the "Formula Amount."  The Revolving Advances shall be evidenced
by secured promissory notes ("Revolving Credit Notes") in favor of each Lender
in substantially in the form attached hereto as Exhibit A.  Borrowers and
                                                ---------
Lenders agree that, if any event occurs or any condition exists that Agent
determines is likely to have a Material Adverse Effect, or if a Default or Event
of Default exists, Agent shall have the right (exercisable at such time or times
as Agent deems appropriate) to require that separate calculations of the
Individual Formula Amount be made for each Borrower, as well as the right to
limit the use of proceeds of Advances by each Borrower to an amount that does
not exceed such Borrower's Individual Formula Amount.

          (b) Discretionary Rights.  The Advance Rate may be increased or
              --------------------
decreased by Agent at any time and from time to time in the exercise of its
reasonable discretion.  Each Borrower consents to any such increases or
decreases and acknowledges that decreasing the Advance Rate or increasing the
reserves may limit or restrict Advances requested by Borrowing Agent.   Agent
shall give Borrowing Agent five (5) Business Days prior written notice of its
intention to decrease the Advance Rates.

          (c) Out-of-Formula Loans.  If the unpaid balance of Revolving Advances
              --------------------
outstanding at any time should exceed the Formula Amount at such time (an "Out-
of-Formula Condition"), such Revolving Advances shall nevertheless constitute
Obligations that are secured by the Collateral and entitled to all of the
benefits of the Loan Documents.  If Agent or Lenders are willing in their sole
and absolute discretion to make Out-of-Formula Loans, such Out-of-Formula Loans
shall be payable on demand and shall bear interest at the Default Rate; provided
                                                                        --------
that, if Lenders do make Out-of-Formula Loans, neither Agent nor Lenders shall
be deemed thereby to have changed the limits of Section 2.1(a) or be obligated
to honor requests for Revolving Advances when an Out-of-Formula Condition exists
or would result therefrom.

          (d) Procedure for Revolving Advances Borrowing.  Except as otherwise
              ------------------------------------------
provided in Section 2.15 below, Borrowing Agent on behalf of any Borrower may
notify Agent prior to 11:00 a.m. on a Business Day of a Borrower's request to
incur, on that day, a Revolving Advance hereunder.  Should any amount required
to be paid as principal or interest hereunder, or under any of the other Loan
Documents, or as fees or other charges under this Agreement or any other
agreement with Agent or Lenders, or with respect to any other Obligation, become
due, same shall be deemed a request for a Revolving Advance as of the date such
payment is due, in the amount required to pay in full such interest, fee, charge
or Obligation under this Agreement or any other agreement with Agent or Lenders,
and such request shall be irrevocable.

     2.2  Disbursement of Advance Proceeds.  All Advances shall be disbursed
          --------------------------------
from whichever office or other place Agent may designate from time to time and,
together with any and all other Obligations of Borrowers to Agent or Lenders,
shall be charged to Borrowers' Account on Agent's books.  During the Term,
Borrowers may use the Revolving Advances by borrowing, prepaying and
reborrowing, all in accordance with the terms and conditions hereof.  The
proceeds of each Revolving Advance requested by Borrowers or deemed to have been
requested by Borrowers under Section 2.1(d) hereof shall, with respect to
requested Revolving Advances to the extent Lenders make such Revolving Advances,
be made available to the Borrowers on the

                                      -21-
<PAGE>

day so requested by way of credit to such operating account at PNC, or such
other bank as Borrowing Agent may designate following notification to Agent, in
immediately available federal funds or other immediately available funds or,
with respect to Revolving Advances deemed to have been requested by any
Borrower, be disbursed to Agent to be applied to the outstanding Obligations
giving rise to such deemed request.

     2.3  Maximum Advances.  The aggregate balance of Revolving Advances
          ----------------
outstanding at any time shall not exceed the lesser of (a) Maximum Revolving
Advance Amount or (b) the Formula Amount.

     2.4  Repayment of Obligations.
          ------------------------

          (a) The Advances and other Obligations shall be due and payable in
full on the last day of the Term subject to earlier prepayment as herein
provided.

          (b) Each Borrower recognizes that the amounts evidenced by checks,
notes, drafts or any other items of payment relating to and/or proceeds of
Collateral may not be collectible by Agent on the date received.  In
consideration of Agent's agreement to conditionally credit Borrowers' Account as
of the Business Day on which Agent receives those items of payment, each
Borrower agrees that, in computing the charges under this Agreement, all items
of payment shall be deemed applied by Agent on account of the Obligations one
(1) Business Day after the Business Day that Agent receives such payments via
wire transfer or electronic depository check.  Agent is not, however, required
to credit Borrowers' Account for the amount of any item of payment that is
unsatisfactory to Agent and Agent may charge Borrowers' Account for the amount
of any item of payment which is returned to Agent unpaid.

          (c) All payments of principal, interest and other amounts payable
hereunder, or under any of the Other Documents shall be made to Agent at the
Payment Office not later than 1:00 p.m. on the due date therefor in Dollars in
federal funds or other funds immediately available to Agent.  Agent and Lenders
shall have the right to effectuate payment on any and all Obligations due and
owing hereunder by charging Borrowers' Account or by making Advances as provided
in Section 2.1 and Section 2.15 hereof.

          (d) Borrowers shall pay principal, interest, and all other amounts
payable hereunder, or under any related agreement, without any deduction
whatsoever, including any deduction for any setoff or counterclaim.

     2.5  Repayment of Excess Advances.  The aggregate balance of Advances
          ----------------------------
outstanding at any time in excess of the maximum amount of Advances permitted
hereunder shall be immediately due and payable without the necessity of any
demand, at the Payment Office, whether or not a Default or Event of Default has
occurred.

     2.6  Statement of Account.  Agent shall maintain, in accordance with its
          --------------------
customary procedures, a loan account ("Borrowers' Account") in the name of
Borrowers in which shall be recorded the date and amount of each Advance made by
Agent and the date and amount of each payment in respect thereof; provided,
                                                                  --------
however, the failure by Agent to record the date and amount of any Advance shall
-------
not adversely affect Agent or any Lender.  Each month, Agent shall send to
Borrowing Agent a statement showing the accounting for the Advances made,
payments made or credited in respect thereof, and other transactions between
Agent and Borrowers during such month.  The monthly statements shall be deemed
correct and binding upon Borrowers in the absence of manifest error and shall
constitute an account stated between Lenders and Borrowers unless Agent receives
a written statement of Borrowers' specific exceptions thereto within thirty (30)
days after such

                                      -22-
<PAGE>

statement is received by Borrowing Agent. The records of Agent with respect to
the Borrowers' Account shall be conclusive evidence absent manifest error of the
amounts of Advances and other charges thereto and of payments applicable
thereto.

     2.7  Letters of Credit.  Subject to the terms and conditions hereof, Agent
          -----------------
shall issue or cause the issuance of standby and documentary letters of credit
("Letters of Credit") on behalf of any Borrower; provided, however, that Agent
                                                 --------  -------
will not be required to issue or cause to be issued any Letters of Credit to the
extent that the face amount of such Letters of Credit then cause the sum of (i)
the outstanding Revolving Advances plus (ii) outstanding Letters of Credit to
                                   ----
exceed the lesser of (x) the Maximum Revolving Advance Amount or (y) the Formula
Amount.  The maximum amount of Letters of Credit outstanding shall not exceed
$3,000,000 in the aggregate.  All disbursements or payments related to Letters
of Credit shall be deemed to be Revolving Advances and shall bear interest at
the Revolving Interest Rate for Domestic Rate Loans. Letters of Credit that have
not been drawn upon shall not bear interest.

     2.8  Issuance of Letters of Credit.
          -----------------------------

          (a) Borrowing Agent, on behalf of Borrowers, may request Agent to
issue or cause the issuance of a Letter of Credit by delivering to Agent at the
Payment Office, Agent's form of Letter of Credit Application (the "Letter of
Credit Application") completed to the satisfaction of Agent; and, such other
certificates, documents and other papers and information as Agent may reasonably
request.  Borrowing Agent, on behalf of Borrowers, also has the right to give
instructions and make agreements with respect to any application, any applicable
letter of credit and security agreement, any applicable letter of credit
reimbursement agreement and/or any other applicable agreement, any letter of
credit and the disposition of documents, disposition of any unutilized funds,
and to agree with Agent upon any amendment, extension or renewal of any Letter
of Credit.

          (b) Each Letter of Credit shall, among other things, (i) provide for
the payment of sight drafts or acceptances of usance drafts when presented for
honor thereunder in accordance with the terms thereof and when accompanied by
the documents described therein and (ii) have an expiry date not later than one
(1) year after such Letter of Credit's date of issuance and in no event later
than sixty (60) days prior to the last day of the Term.  Each Letter of Credit
shall be subject to the Uniform Customs and Practice for Documentary Credits
(1993 Revision), International Chamber of Commerce Publication No. 500, and any
amendments or revision thereof adhered to by the Issuer and, to the extent not
inconsistent therewith, the laws of the State of New Jersey.

          (c) Agent shall use its reasonable efforts to notify Lenders of the
request by Borrowing Agent for a Letter of Credit hereunder.

          (d) Agent shall have absolute discretion whether to accept any draft.
Without in any way limiting Agent's absolute discretion whether to accept any
draft, Borrowing Agent will not present for acceptance any draft, and Agent will
generally not accept any drafts (i) that arise out of transactions involving the
sale of goods by any Borrower not in the ordinary course of its business, (ii)
that involve a sale to an Affiliate of any Borrower, (iii) that involve any
purchase for which Agent has not received all related documents, instruments and
forms requested by Agent, (iv) for which Agent is unable to locate a purchaser
in the ordinary course of business on standard terms, or (v) that is not
eligible for discounting with Federal Reserve Banks pursuant to paragraph 7 of
Section 13 of the Federal Reserve Act.

     2.9  Requirements For Issuance of Letters of Credit.
          ----------------------------------------------

          (a) In connection with the issuance of any Letter of Credit, Borrowers
shall indemnify, save and hold Agent, each Lender and each Issuer harmless from
any loss, cost, expense or liability, including payments made by Agent, any
Lender or any Issuer and expenses and reasonable attorneys' fees incurred by
Agent, any Lender or Issuer arising out of, or in connection with, any Letter of
Credit to be issued or created for any Borrower.  Borrowers shall be bound by
Agent's or any Issuer's regulations and good faith interpretations of any Letter
of Credit issued or created for Borrowers' Account, although this interpretation
may be different from its own; and, neither Agent, nor any Lender, nor any
Issuer nor any of their correspondents shall be liable for any error,
negligence, or mistakes, whether of omission or commission, in following
Borrowing Agent's or any Borrower's instructions or those contained in any
Letter of Credit or of any modifications, amendments or supplements thereto or
in issuing or paying any Letter of Credit, except for Agent's, any Lender's, any
Issuer's or such correspondents' willful misconduct or gross negligence.

          (b) Borrowing Agent shall authorize and direct any Issuer to name the
applicable Borrower as the "Applicant" or "Account Party" of each Letter of
Credit.  If Agent is not the Issuer of any Letter of Credit, Borrower shall
authorize and direct the Issuer to deliver to Agent all instruments, documents,
and other writings and property received by the Issuer pursuant to the Letter of
Credit and to accept and rely upon Agent's instructions and agreements with
respect to all matters arising in connection with the Letter of Credit, the
application therefor or any acceptance therefor.

          (c) In connection with all Letters of Credit issued or caused to be
issued by Agent under this Agreement, each Borrower hereby appoints Agent, or
its designee, as its attorney, with full power and authority (i) to sign and/or
endorse such Borrower's name upon any warehouse or other receipts, letter of
credit applications and acceptances; (ii) to sign such Borrower's name on bills
of lading; (iii) to clear Inventory through the United States of America Customs
Department ("Customs") in the name of such Borrower or Agent or Agent's
designee, and to sign and deliver to Customs officials powers of attorney in the
name of such Borrower for such purpose; and (iv) to complete in such Borrower's
name or Agent's, or in the name of Agent's designee, any order, sale or
transaction, obtain the necessary documents in connection therewith, and collect
the proceeds thereof.  Neither Agent nor its attorneys will be liable for any
acts or omissions nor for any error of judgment or mistakes of fact or law,
except for Agent's or its attorney's willful misconduct.  This power, being
coupled with an interest, is irrevocable as long as any Letters of Credit remain
outstanding.

          (d) Each Lender shall to the extent of the percentage amount equal to
the product of such Lender's Commitment Percentage times the aggregate amount of
all unreimbursed reimbursement obligations arising from disbursements made or
obligations incurred with respect to the Letters of Credit be deemed to have
irrevocably purchased an undivided participation in each such unreimbursed
reimbursement obligation.  In the event that at the time a disbursement is made
the unpaid balance of Revolving Advances exceeds or would exceed, with the
making of such disbursement, the lesser of (i) the Maximum Revolving Advance
Amount or (ii) the Formula Amount, and such disbursement is not reimbursed by
Borrowers within two (2) Business Days, Agent shall promptly notify each Lender
and upon Agent's demand each Lender shall pay to Agent such Lender's
proportionate share of such unreimbursed disbursement together with such
Lender's proportionate share of Agent's unreimbursed costs and expenses relating
to such unreimbursed disbursement.  Upon receipt by Agent of a repayment from
any Borrower of any amount disbursed by Agent for which Agent had already been
reimbursed by Lenders, Agent shall deliver to each Lender that Lender's pro rata
share of such repayment.  Each Lender's participation commitment shall continue
until the last to occur of any of the following events: (A) Agent ceases to be
obligated to issue or cause to be issued Letters of Credit hereunder; (B) no
Letter of

                                      -24-
<PAGE>

Credit issued hereunder remains outstanding and uncanceled; or (C) all Persons
(other than the applicable Borrower) have been fully reimbursed for all payments
made under or relating to Letters of Credit.

          (e) Upon or after the occurrence of a Default or an Event of Default,
Borrowers will cause cash to be deposited and maintained in an account with
Agent, as cash collateral, in an amount equal to one hundred and five percent
(105%) of the outstanding Letters of Credit, and each Borrower hereby
irrevocably authorizes Agent, in its discretion, on such Borrower's behalf and
in such Borrower's name, to open such an account and to make and maintain
deposits therein, or in an account opened by such Borrower, in the amounts
required to be made by such Borrower, out of the proceeds of Receivables or
other Collateral or out of any other funds of such Borrower coming into any
Lender's possession at any time.  Agent will invest such cash collateral (less
applicable reserves) in such short-term money-market items as to which Agent and
such Borrower mutually agree and the net return on such investments shall be
credited to such account and constitute additional cash collateral.  No Borrower
may withdraw amounts credited to any such account except upon payment and
performance in full of all Obligations and termination of this Agreement.

     2.10  Additional Payments.  Any sums expended by Agent or any Lender due to
           -------------------
any Borrower's failure to perform or comply with its obligations under this
Agreement or any Other Document, including any Borrower's obligations under
Sections 4.2, 4.4, 4.12, 4.13, 4.14 and 6.1 hereof, may be charged to Borrowers'
Account as a Revolving Advance of a Domestic Rate Loan and added to the
Obligations.

     2.11  Manner of Borrowing and Payment.
           -------------------------------

          (a) Each borrowing of Revolving Advances shall be advanced according
to the Commitment Percentages of Lenders.

          (b) Each payment (including each prepayment) by Borrowers on account
of the principal of and interest on the Revolving Advances, shall be applied to
the Revolving Advances pro rata according to the applicable Commitment
Percentages of Lenders.  Except as expressly provided herein, all payments
(including prepayments) to be made by any Borrower on account of principal,
interest and fees shall be made without set off or counterclaim and shall be
made to Agent on behalf of the Lenders to the Payment Office, in each case on or
prior to 1:00 p.m., in Dollars and in immediately available funds.

          (c) (i)  Notwithstanding anything to the contrary contained in
Sections 2.11(a) and (b) hereof, commencing with the first Business Day
following the Closing Date, each borrowing of Revolving Advances shall be
advanced by Agent and each payment by any Borrower on account of Revolving
Advances shall be applied first to those Revolving Advances advanced by Agent.
On or before 1:00 p.m. on each Settlement Date commencing with the first
Settlement Date following the Closing Date, Agent and Lenders shall make certain
payments as follows: (i) if the aggregate amount of new Revolving Advances made
by Agent during the preceding Week (if any) exceeds the aggregate amount of
repayments applied to outstanding Revolving Advances during such preceding Week,
then each Lender shall provide Agent with funds in an amount equal to its
applicable Commitment Percentage of the difference between (w) such Revolving
Advances and (x) such repayments and (ii) if the aggregate amount of repayments
applied to outstanding Revolving Advances during such Week exceeds the aggregate
amount of new Revolving Advances made during such Week, then Agent shall provide
each Lender with funds in an amount equal to such Lender's applicable Commitment
Percentage of the difference between (y) such repayments and (z) such Revolving
Advances.

                                      -25-
<PAGE>

               (ii) Each Lender shall be entitled to earn interest at the
applicable Revolving Interest Rate on outstanding Advances which it has funded.

               (iii) Promptly following each Settlement Date, Agent shall submit
to each Lender a certificate with respect to payments received and Advances made
during the Week immediately preceding such Settlement Date.  Such certificate of
Agent shall be conclusive in the absence of manifest error.

          (d) If any Lender or Participant (a "benefitted Lender") shall at any
time receive any payment of all or part of its Advances, or interest thereon, or
receive any Collateral in respect thereof (whether voluntarily or involuntarily
or by set-off) in a greater proportion than any such payment to and Collateral
received by any other Lender, if any, in respect of such other Lender's
Advances, or interest thereon, and such greater proportionate payment or receipt
of Collateral is not expressly permitted hereunder, such benefitted Lender shall
purchase for cash from the other Lenders a participation in such portion of each
such other Lender's Advances, or shall provide such other Lender with the
benefits of any such Collateral, or the proceeds thereof, as shall be necessary
to cause such benefitted Lender to share the excess payment or benefits of such
Collateral or proceeds ratably with each of the other Lenders; provided,
                                                               --------
however, that if all or any portion of such excess payment or benefits is
-------
thereafter recovered from such benefitted Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest.  Each Lender so purchasing a portion of another
Lender's Advances may exercise all rights of payment (including rights of set-
off) with respect to such portion as fully as if such Lender were the direct
holder of such portion.

          (e) Unless Agent shall have been notified by telephone, confirmed in
writing, by any Lender that such Lender will not make the amount which would
constitute its applicable Commitment Percentage of the Advances available to
Agent, Agent may (but shall not be obligated to) assume that such Lender shall
make such amount available to Agent on the next Settlement Date and, in reliance
upon such assumption, make available to Borrowers a corresponding amount.  Agent
will promptly notify Borrowers of its receipt of any such notice from a Lender.
If such amount is made available to Agent on a date after such next Settlement
Date, such Lender shall pay to Agent on demand an amount equal to the product of
(i) the daily average Federal Funds Rate (computed on the basis of a year of 360
days) during such period as quoted by Agent, times (ii) such amount, times (iii)
the number of days from and including such Settlement Date to the date on which
such amount becomes immediately available to Agent.  A certificate of Agent
submitted to any Lender with respect to any amounts owing under this paragraph
(e) shall be conclusive, in the absence of manifest error.  If such amount is
not in fact made available to Agent by such Lender within three (3) Business
Days after such Settlement Date, Agent shall be entitled to recover such an
amount, with interest thereon at the rate per annum then applicable to such
Revolving Advances hereunder, on demand from Borrowers; provided, however, that
                                                        --------  -------
Agent's right to such recovery shall not prejudice or otherwise adversely affect
Borrowers' rights (if any) against such Lender.

     2.12  Mandatory Prepayments.  Subject to Section 4.3 hereof, when any
           ---------------------
Borrower sells or otherwise disposes of any Collateral other than Inventory in
the Ordinary Course of Business, Borrowers shall repay the Advances in an amount
equal to the net proceeds of such sale (i.e., gross proceeds less the reasonable
costs of such sales or other dispositions), such repayments to be made promptly
but in no event more than one (1) Business Day following receipt of such net
proceeds, and until the date of payment, such proceeds shall be held in trust
for Agent.  The foregoing shall not be deemed to be implied consent to any such
sale otherwise prohibited by the terms and conditions hereof. Such repayments
shall be applied first, to the Obligations in such

                                      -26-
<PAGE>

order as Agent may determine, subject to Borrowers' ability to reborrow
Revolving Advances in accordance with the terms hereof.

     2.13  Use of Proceeds.  Borrowers shall apply the proceeds of Advances to
           ---------------
(i) repay existing indebtedness owed to Citizens Bank, (ii) pay fees and
expenses relating to this transaction, (iii) provide for Borrowers' working
capital needs, and (iv) to reimburse Issuer for Letters of Credit.

     2.14  Defaulting Lender.
           -----------------

          (a) Notwithstanding anything to the contrary contained herein, in the
event any Lender (x) has refused (which refusal constitutes a breach by such
Lender of its obligations under this Agreement) to make available its portion of
any Advance or (y) notifies either Agent or Borrowing Agent that it does not
intend to make available its portion of any Advance (if the actual refusal would
constitute a breach by such Lender of its obligations under this Agreement)
(each, a "Lender Default"), all rights and obligations hereunder of such Lender
(a "Defaulting Lender") as to which a Lender Default is in effect and of the
other parties hereto shall be modified to the extent of the express provisions
of this Section 2.15 while such Lender Default remains in effect.

          (b) Advances shall be incurred pro rata from Lenders (the "Non-
Defaulting Lenders") which are not Defaulting Lenders based on their respective
Commitment Percentages, and no Commitment Percentage of any Lender or any pro
rata share of any Advances required to be advanced by any Lender shall be
increased as a result of such Lender Default.  Amounts received in respect of
principal of any type of Advances shall be applied to reduce the applicable
Advances of each Lender pro rata based on the aggregate of the outstanding
Advances of that type of all Lenders at the time of such application; provided,
that, such amount shall not be applied to any Advances of a Defaulting Lender at
any time when, and to the extent that, the aggregate amount of Advances of any
Non-Defaulting Lender exceeds such Non-Defaulting Lender's Commitment Percentage
of all Advances then outstanding.

          (c) A Defaulting Lender shall not be entitled to give instructions to
Agent or to approve, disapprove, consent to or vote on any matters relating to
this Agreement and the Other Documents.  All amendments, waivers and other
modifications of this Agreement and the Other Documents may be made without
regard to a Defaulting Lender and, for purposes of the definition of "Required
Lenders," a Defaulting Lender shall be deemed not to be a Lender and not to have
Advances outstanding.

          (d) Other than as expressly set forth in this Section 2.15, the rights
and obligations of a Defaulting Lender (including the obligation to indemnify
Agent) and the other parties hereto shall remain unchanged.  Nothing in this
Section 2.15 shall be deemed to release any Defaulting Lender from its
obligations under this Agreement and the Other Documents, shall alter such
obligations, shall operate as a waiver of any default by such Defaulting Lender
hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender
may have against any Defaulting Lender as a result of any default by such
Defaulting Lender hereunder.

          (e) In the event a Defaulting Lender retroactively cures to the
satisfaction of Agent the breach which caused a Lender to become a Defaulting
Lender, such Defaulting Lender shall no longer be a Defaulting Lender and shall
be treated as a Lender under this Agreement.

     2.15  Provisions Applicable to Eurodollar Rate Loans.
           ----------------------------------------------

          (a) Notwithstanding the provisions of Section 2.1 above, in the event
any Borrower desires to obtain a Eurodollar Rate Loan, Borrowing Agent shall
give Agent at least three (3) Business Days prior written notice, specifying (i)
the date of the proposed borrowing (which shall be a Business Day), (ii) the
type of borrowing and the amount on the date of such Advance to be borrowed,
which amount shall be in a minimum amount of $1,000,000 and integral multiples
of $100,000 in excess thereof, and (iii) the duration of the first Interest
Period therefor.  Interest Periods for Eurodollar Rate Loans shall be for one,
two or three months; provided, if an Interest Period would end on a day that is
not a Business Day, it shall end on the next succeeding Business Day unless such
day falls in the next succeeding calendar month in which case the Interest
Period shall end on the next preceding Business Day.  No Eurodollar Rate Loan
shall be made available to Borrower during the continuance of a Default or an
Event of Default.

          (b) Each Interest Period of a Eurodollar Rate Loan shall commence on
the date such Eurodollar Rate Loan is made and shall end on such date as
Borrowing Agent may elect as set forth in (a)(iii) above provided that the exact
length of each Interest Period shall be determined in accordance with the
practice of the interbank market for offshore Dollar deposits and no Interest
Period shall end after the last day of the Term.

     Borrowing Agent shall elect the initial Interest Period applicable to a
Eurodollar Rate Loan by its notice of borrowing given to Agent pursuant to
Section 2.15(a) or by its notice of conversion given to Agent pursuant to
Section 2.15(c), as the case may be.  Borrowing Agent shall elect the duration
of each succeeding Interest Period by giving irrevocable written notice to Agent
of such duration not less than three (3) Business Days prior to the last day of
the then current Interest Period applicable to such Eurodollar Rate Loan.  If
Agent does not receive timely notice of the Interest Period elected by Borrowing
Agent, Borrowers shall be deemed to have elected to convert to a Domestic Rate
Loan subject to Section 2.15(c) herein below.

          (c) Provided that no Event of Default shall have occurred and be
continuing, Borrowing Agent may, on the last Business Day of the then current
Interest Period applicable to any outstanding Eurodollar Rate Loan, or on any
Business Day with respect to Domestic Rate Loans, convert any such loan into a
loan of another type in the same aggregate principal amount provided that any
conversion of a Eurodollar Rate Loan shall be made only on the last Business Day
of the then current Interest Period applicable to such Eurodollar Rate Loan.  If
Borrowing Agent desires to convert a loan, Borrowing Agent shall give Agent not
less than three (3) Business Days' prior written notice to convert from a
Domestic Rate Loan to a Eurodollar Rate Loan or one (1) Business Day's prior
written notice to convert from a Eurodollar Rate Loan to a Domestic Rate Loan,
specifying the date of such conversion, the loans to be converted and if the
conversion is from a Domestic Rate Loan to any other type of loan, the duration
of the first Interest Period therefor.  After giving effect to each such
conversion, there shall not be outstanding more than three (3) Eurodollar Rate
Loans, in the aggregate.

          (d) Borrowers shall jointly and severally indemnify Agent and Lenders
and hold Agent and Lenders harmless from and against any and all losses or
expenses that Agent and Lenders may sustain or incur as a consequence of any
prepayment, conversion of or any default by Borrowers in the payment of the
principal of or interest on any Eurodollar Rate Loan or failure by Borrowers to
complete a borrowing of, a prepayment of or conversion of or to a Eurodollar
Rate Loan after notice thereof has been given, including any interest payable by
Agent or Lenders to lenders of funds obtained by it in order to make or maintain
its Eurodollar Rate Loans hereunder.  A certificate prepared in good faith as to
any additional amounts payable

                                      -28-
<PAGE>

pursuant to the foregoing sentence submitted by Agent or any Lender to Borrowing
Agent shall be conclusive absent manifest error.

          (e) Notwithstanding any other provision hereof, if any applicable law,
treaty, regulation or directive, or any change therein or in the interpretation
or application thereof, shall make it unlawful for any Lender (for purposes of
this subsection (g), the term "Lender" shall include any Lender and the office
or branch where any Lender or any corporation or bank controlling such Lender
makes or maintains any Eurodollar Rate Loans) to make or maintain its Eurodollar
Rate Loans, the obligation of Lenders to make Eurodollar Rate Loans hereunder
shall forthwith be canceled and Borrowers shall, if any affected Eurodollar Rate
Loans are then outstanding, promptly upon request from Agent, either pay all
such affected Eurodollar Rate Loans or convert such affected Eurodollar Rate
Loans into loans of another type.  If any such payment or conversion of any
Eurodollar Rate Loan is made on a day that is not the last day of the Interest
Period applicable to such Eurodollar Rate Loan, Borrowers shall pay Agent, upon
Agent's request, such amount or amounts as may be necessary to compensate
Lenders for any loss or expense sustained or incurred by Lenders in respect of
such Eurodollar Rate Loan as a result of such payment or conversion, including
any interest or other amounts payable by Lenders to lenders of funds obtained by
Lenders in order to make or maintain such Eurodollar Rate Loan.  A certificate
prepared in good faith as to any additional amounts payable pursuant to the
foregoing sentence submitted by Lenders to Borrowing Agent shall be conclusive
absent manifest error.

SECTION 3.  INTEREST AND FEES.
            ------------------

     3.1  Interest. Interest on Advances shall accrue and be payable monthly, in
          --------
arrears on the last day of each month with respect to Domestic Rate Loans and,
with respect to Eurodollar Rate Loans, at the end of each Interest Period or,
for Eurodollar Rate Loans with an Interest Period in excess of three (3) months,
at the earlier of (a) each three (3) months on the anniversary date of the
commencement of such Eurodollar Rate Loan or (b) the end of the Interest Period.
Interest charges shall be computed on the actual principal amount of Advances
outstanding during the month (the "Monthly Advances") at a rate per annum equal
to, with respect to Revolving Advances, the applicable Revolving Interest Rate.
Whenever, subsequent to the date of this Agreement, the Alternate Base Rate is
increased or decreased, the Revolving Interest Rate for Domestic Rate Loans
shall be similarly changed without notice or demand of any kind by an amount
equal to the amount of such change in the Alternate Base Rate during the time
such change or changes remain in effect.  The Eurodollar Rate shall be adjusted
with respect to Eurodollar Rate Loans without notice or demand of any kind on
the effective date of any change in the Reserve Percentage as of such effective
date.  Upon and after the occurrence of an Event of Default, and during the
continuation thereof, (i) the Obligations other than Eurodollar Rate Loans shall
bear interest at the Revolving Interest Rate for Domestic Loans plus two percent
                                                                ----
(2%) per annum and (ii) Eurodollar Rate Loans shall bear interest at the
Revolving Interest Rate for Eurodollar Rate Loans plus two percent (2.0%) per
                                                  ----
annum (as applicable, the "Default Rate").

     3.2  Letter of Credit Fees.   Borrowers shall pay (x) to Agent, for the
          ---------------------
benefit of Lenders, fees for each Letter of Credit for the period from and
excluding the date of issuance of same to and including the date of expiration
or termination, equal to the average daily face amount of each outstanding
Letter of Credit multiplied by two percent (2.0%) per annum, such fees to be
calculated on the basis of a 360-day year for the actual number of days elapsed
and to be payable monthly in arrears on the first day of each month and on the
last day of the Term and (y) to the Issuer, any and all fees and expenses as
agreed upon by the Issuer and the Borrowing Agent in connection with any Letter
of Credit, including in connection with the opening, amendment or renewal of any
such Letter of Credit and any acceptances created thereunder and shall reimburse
Agent for any and all fees and expenses, if any, paid by Agent to the Issuer
(all of the foregoing fees, the "Letter of Credit

                                      -29-
<PAGE>

Fees"). All such charges shall be deemed earned in full on the date when the
same are due and payable hereunder and shall not be subject to rebate or
proration upon the termination of this Agreement for any reason. Any such charge
in effect at the time of a particular transaction shall be the charge for that
transaction, notwithstanding any subsequent change in the Issuer's prevailing
charges for that type of transaction. All Letter of Credit Fees payable
hereunder shall be deemed earned in full on the date when the same are due and
payable hereunder and shall not be subject to rebate or proration upon the
termination of this Agreement for any reason.

     3.3  Closing and Facility Fees.
          -------------------------

          (a) Upon the execution of this Agreement, Borrowers shall pay to
Agent, for the ratable benefit of those Lenders who are parties to this
Agreement on the Closing Date, a closing fee of $50,000.

          (b) If, for any month during the Term, the average daily unpaid
balance of the Advances for each day of such month does not equal the Maximum
Revolving Advance Amount, then Borrowers shall pay to Agent for the ratable
benefit of Lenders a fee at a rate equal to one-quarter of one percent (0.25%)
per annum on the amount by which the Maximum Revolving Advance Amount exceeds
such average daily unpaid balance.  Such fee shall be payable to Agent on the
last day of each month.

     3.4  Collateral Evaluation and Monitoring Fee.
          ----------------------------------------

          (a) Borrowers shall pay Agent a collateral evaluation fee equal to
$1,000 per month, commencing on the first day of the month following the Closing
Date and on the first day of each month thereafter during the Term.  The
collateral evaluation fee shall be deemed earned in full on the date when same
is due and payable hereunder and shall not be subject to rebate or proration
upon termination of this Agreement for any reason.

          (b) Borrowers shall pay to Agent on the first day of each month
following any month in which Agent performs any collateral monitoring - namely
any field examination, collateral analysis or other business analysis, the need
for which is to be determined by Agent and which monitoring is undertaken by
Agent or for Agent's benefit - a collateral monitoring fee in an amount equal to
$750 per day for each person (other than Agent's management personnel) employed
to perform such monitoring and in an amount equal to $750 per day for each
manager of Agent performing such monitoring, plus all costs and disbursements
                                             ----
incurred by Agent in the performance of such examination or analysis.

     3.5  Computation of Interest and Fees.  Interest and fees hereunder shall
          --------------------------------
be computed on the basis of a year of 360 days and for the actual number of days
elapsed.  If any payment to be made hereunder becomes due and payable on a day
other than a Business Day, the due date thereof shall be extended to the next
succeeding Business Day and interest thereon shall be payable at the Revolving
Interest Rate for Domestic Rate Loans during such extension.

     3.6  Maximum Charges.  In no event whatsoever shall interest and other
          ---------------
charges charged hereunder exceed the highest rate permissible under Applicable
Law. In the event interest and other charges as computed hereunder would
otherwise exceed the highest rate permitted under Applicable Law, such excess
amount shall be first applied to any unpaid principal balance owed by Borrowers,
and if the then remaining excess amount is greater than the previously unpaid
principal balance, Lenders shall promptly refund such excess amount to Borrowers
and the provisions hereof shall be deemed amended to provide for such
permissible rate.

                                      -30-
<PAGE>

     3.7  Increased Costs.  In the event that any Applicable Law, treaty or
          ---------------
governmental regulation, or any change therein or in the interpretation or
application thereof, or compliance by any Lender (for purposes of this Section
3.7, the term "Lender" shall include Agent or any Lender and any corporation or
bank controlling Agent or any Lender) and the office or branch where Agent or
any Lender (as so defined) makes or maintains any Eurodollar Rate Loans with any
request or directive (whether or not having the force of law) from any central
bank or other financial, monetary or other authority, shall:

          (a) subject Agent or any Lender to any tax of any kind whatsoever with
respect to this Agreement or any Other Document or change the basis of taxation
of payments to Agent or any Lender of principal, fees, interest or any other
amount payable hereunder or under any Other Documents (except for changes in the
rate of tax on the overall net income of Agent or any Lender by the jurisdiction
in which it maintains its principal office);

          (b) impose, modify or hold applicable any reserve, special deposit,
assessment or similar requirement against assets held by, or deposits in or for
the account of, advances or loans by, or other credit extended by, any office of
Agent or any Lender, including pursuant to Regulation D of the Board of
Governors of the Federal Reserve System; or

          (c) impose on Agent or any Lender or the London interbank Eurodollar
market any other condition with respect to this Agreement or any Other Document;

and the result of any of the foregoing is to increase the cost to Agent or any
Lender of making, renewing or maintaining its Advances hereunder by an amount
that Agent or such Lender deems to be material or to reduce the amount of any
payment (whether of principal, interest or otherwise) in respect of any of the
Advances by an amount that Agent or such Lender deems to be material, then, in
any case Borrowers shall promptly pay Agent or such Lender, upon its demand,
such additional amount as will compensate Agent or such Lender for such
additional cost or such reduction, as the case may be, provided that the
foregoing shall not apply to increased costs which are reflected in the
Eurodollar Rate.  Agent or such Lender shall certify in good faith the amount of
such additional cost or reduced amount to Borrowers, and such certification
shall be conclusive absent manifest error.

     3.8  Basis For Determining Interest Rate Inadequate or Unfair.  In the
          --------------------------------------------------------
event that Agent or any Lender shall have determined that:

          (a) reasonable means do not exist for ascertaining the Eurodollar Rate
applicable pursuant to Section 2.15 hereof for any Interest Period; or

          (b) Dollar deposits in the relevant amount and for the relevant
maturity are not available in the London interbank Eurodollar market, with
respect to an outstanding Eurodollar Rate Loan, a proposed Eurodollar Rate Loan,
or a proposed conversion of a Domestic Rate Loan into a Eurodollar Rate Loan,
then Agent shall give Borrowing Agent prompt written, telephonic or telegraphic
notice of such determination.  If such notice is given, (i) any such requested
Eurodollar Rate Loan shall be made as a Domestic Rate Loan, unless Borrowing
Agent shall notify Agent no later than 10:00 a.m. two (2) Business Days prior to
the date of such proposed borrowing, that its request for such borrowing shall
be cancelled or made as an unaffected type of Eurodollar Rate Loan, (ii) any
Domestic Rate Loan or Eurodollar Rate Loan that was to have been

                                      -31-
<PAGE>

converted to an affected type of Eurodollar Rate Loan shall be continued as or
converted into a Domestic Rate Loan, or, if Borrowing Agent shall notify Agent,
no later than 10:00 a.m. two (2) Business Days prior to the proposed conversion,
shall be maintained as an unaffected type of Eurodollar Rate Loan, and (iii) any
outstanding affected Eurodollar Rate Loans shall be converted into a Domestic
Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 10:00 a.m.
two (2) Business Days prior to the last Business Day of the then current
Interest Period applicable to such affected Eurodollar Rate Loan, shall be
converted into an unaffected type of Eurodollar Rate Loan, on the last Business
Day of the then current Interest Period for such affected Eurodollar Rate Loans.
Until such notice has been withdrawn, Lenders shall have no obligation to make
an affected type of Eurodollar Rate Loan or maintain outstanding affected
Eurodollar Rate Loans and no Borrower shall have the right to convert a Domestic
Rate Loan or an unaffected type of Eurodollar Rate Loan into an affected type of
Eurodollar Rate Loan.

     3.9  Capital Adequacy.
          ----------------

          (a) In the event that Agent or any Lender shall have determined that
any Applicable Law, rule, regulation or guideline regarding capital adequacy, or
any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by Agent or any
Lender (for purposes of this Section 3.9, the term "Lender" shall include Agent
or any Lender and any corporation or bank controlling Agent or any Lender) and
the office or branch where Agent or any Lender (as so defined) makes or
maintains any Eurodollar Rate Loans with any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on Agent's or any Lender's capital as a consequence of its
obligations hereunder to a level below that which Agent or such Lender could
have achieved but for such adoption, change or compliance (taking into
consideration Agent's and each Lender's policies with respect to capital
adequacy) by an amount deemed by Agent or any Lender to be material, then, from
time to time, Borrowers shall pay upon demand to Agent or such Lender such
additional amount or amounts as will compensate Agent or such Lender for such
reduction.  In determining such amount or amounts, Agent or such Lender may use
any reasonable averaging or attribution methods.  The protection of this Section
3.9 shall be available to Agent and each Lender regardless of any possible
contention of invalidity or inapplicability with respect to any Applicable Law
or condition.

          (b) A certificate prepared in good faith of Agent or such Lender
setting forth such amount or amounts as shall be necessary to compensate Agent
or such Lender with respect to Section 3.9(a) hereof when delivered to Borrowing
Agent shall be conclusive absent manifest error.

Agent and each Lender any information such accountants may have concerning such
Borrower's financial status and business operations.  Each Borrower hereby
authorizes all federal, state and municipal authorities to furnish to Agent and
each Lender copies of reports or examinations relating to such Borrower, whether

obtaining such information or materials from such accountants or such
authorities.

     4.9  Compliance with Laws.  Each Borrower shall comply with all Applicable
          --------------------
Law with respect to its respective Collateral or any part thereof or to the
operation of such Borrower's business the

                                      -34-
<PAGE>

non-compliance with which could reasonably be expected to have a Material
Adverse Effect on such Borrower. Each Borrower may, however, contest or dispute
any acts, rules, regulations, orders and directions of those bodies or officials
in any reasonable manner, provided that such contest or dispute is pursued
diligently, in good faith and by appropriate proceedings, any related Lien has
not attached to any Collateral or been stayed and sufficient reserves are
established to the reasonable satisfaction of Agent to protect Agent's Lien on
or security interest in the Collateral. The Collateral and other assets of
Borrowers at all times shall be maintained in accordance with the requirements
of all insurance carriers which provide insurance with respect to the Collateral
and such other assets of Borrowers so that such insurance shall remain in full
force and effect.

Borrower's business.  Agent, any Lender and their agents may enter upon any of
Borrower's premises at any time during business hours and at any other
reasonable time, and from time to time, for the purpose of inspecting the

Borrower's business.

     4.11  Insurance.  Each Borrower shall bear the full risk of any loss of any
           ---------
nature whatsoever with respect to the Collateral.  At each Borrower's own cost
and expense in amounts and with carriers acceptable to Agent, each Borrower
shall (a) keep all its properties in which it has an interest insured against
the hazards of fire, flood, sprinkler leakage, those hazards covered by extended
coverage insurance and such other hazards, and for such amounts, as is customary
in the case of companies engaged in businesses similar to such Borrower's
including business interruption insurance; (b) maintain a bond in such amounts
as is customary in the case of companies engaged in businesses similar to such
Borrower insuring against larceny, embezzlement or other criminal
misappropriation of insured's officers and employees who may either singly or
jointly with others at any time have access to the assets or funds of such
Borrower either directly or through authority to draw upon such funds or to
direct generally the disposition of such assets; (c) maintain public and product
liability insurance against claims for personal injury, death or property damage
suffered by others; (d) maintain all such worker's compensation or similar
insurance as may be required under the laws of any state or jurisdiction in
which such Borrower is engaged in business; (e) furnish Agent with (i) copies of
all policies and evidence of the maintenance of such policies by the renewal
thereof at least thirty (30) days before any expiration date, and (ii)
appropriate loss payable endorsements in form and substance satisfactory to
Agent, naming Agent as a co-insured and loss payee as its interests may appear
with respect to all insurance coverage referred to in clauses (a) and (c) above,
and providing (A) that all proceeds thereunder shall be payable to Agent, (B) no
such insurance shall be affected by any act or neglect of the insured or owner
of the property described in such policy, and (C) that such policy and loss
payable clauses may not be cancelled, amended or terminated unless at least
thirty (30) days prior written notice is given to Agent.  In the event of any
loss thereunder, the carriers named therein are hereby directed by Agent and the
applicable Borrower to make payment for such loss to Agent and not to such
Borrower and Agent jointly. If any insurance losses are paid by check, draft or
other instrument payable to any Borrower and Agent jointly, Agent may endorse
such Borrower's name thereon and do such other things as Agent may deem
advisable to reduce the same to cash.  When any Event of Default exists, Agent
is hereby authorized to adjust and compromise claims under insurance coverage
referred to in clauses (a) and (b) above.  All loss recoveries received by Agent
upon any such insurance may be applied to the Obligations, in such order as
Agent in its sole discretion shall determine.  Any surplus shall be paid by
Agent to Borrowers or applied as may be otherwise required by law.  Any
deficiency thereon shall be paid by Borrowers to Agent, on demand.

     4.12  Failure to Pay Insurance.  If any Borrower fails to obtain insurance
           ------------------------
as hereinabove provided, or to keep the same in force, Agent, if Agent so
elects, may obtain such insurance and pay the premium therefor on behalf of
Borrower, and charge Borrowers' Account therefor as a Revolving Advance of a
Domestic Rate Loan and such expenses so paid shall be part of the Obligations.

     4.13  Payment of Taxes.  Each Borrower will pay, when due, all Charges
           ----------------
lawfully levied or assessed upon such Borrower or any of the Collateral
including real and personal property taxes, assessments and charges and all
franchise, income, employment, social security benefits, withholding, and sales
taxes. If any tax by any governmental authority is or may be imposed on or as a
result of any transaction between any Borrower and Agent or any Lender which
Agent or any Lender may be required to withhold or pay or if any Charges remain
unpaid after the date fixed for their payment, or if any claim shall be made
which, in Agent's or any Lender's opinion, may possibly create a valid Lien on
the Collateral, Agent may without notice to Borrowers pay the Charges and each
Borrower hereby indemnifies and holds Agent and each Lender harmless in respect
thereof.  The amount of any payment by Agent under this Section 4.13 shall be
charged to Borrowers' Account as a Revolving Advance and added to the
Obligations and, until Borrowers shall furnish Agent with an indemnity therefor
(or supply Agent with evidence satisfactory to Agent that due provision for the
payment thereof has been made), Agent may hold without interest any balance
standing to Borrowers' credit and Agent shall retain its security interest in
any and all Collateral held by Agent.

     4.14  Payment of Leasehold Obligations.  Each Borrower shall at all times
           --------------------------------
pay, when and as due, its rental obligations under all leases under which it is

request will provide evidence of having done so.

rendered by a Borrower as of the date each Receivable is created.  Same shall be

full when due or with respect to such Customers of any Borrower who are not
Solvent such Borrower has set up on its books and in its financial records bad
debt reserves adequate to cover such Receivables.

Borrower keeps its records pertaining to Receivables, all such records shall be
kept at such executive office; provided, however, Squirrel may maintain such
                               --------  -------

          (d) Collection of Receivables.  Until any Borrower's authority to do
              -------------------------
so is terminated by Agent (which notice Agent may give at any time following the
occurrence of a Default or an Event of Default), each Borrower will, at such
Borrower's sole cost and expense, but on Agent's and Lenders' behalf and for
Agent's and Lenders' account, collect as Agent's property and in trust for Agent
all amounts received on Receivables, and shall not commingle such collections
with any Borrower's funds in which Agent does not have a lien or use the same
except to pay Obligations.  Each Borrower shall, upon request, deliver to Agent,

              ------------------------------------------
right to receive, endorse, assign and/or deliver in the name of Agent or any
Borrower any and all checks, drafts and other instruments for the payment of

mistake of fact or of law, unless done maliciously or with gross (not mere)
negligence; this power being coupled with an interest is irrevocable while any

              ------------
circumstances or in any event whatsoever, have any liability for any error or
omission or delay of any kind occurring in the settlement,

placed any Hazardous Substances on any Real Property except to the extent
permitted by Applicable Law.

          (b) Borrowers shall establish and maintain a system to assure and
monitor continued compliance with all applicable Environmental Laws which system
shall include periodic reviews of such compliance.

          (c) Borrowers shall (i) employ in connection with the use of the Real
Property appropriate technology necessary to maintain compliance with any
applicable Environmental Laws and (ii) dispose of any and all Hazardous Waste
generated at the Real Property only at facilities and with carriers that

Borrowers shall use their best efforts to obtain certificates of disposal, such
as hazardous waste manifest receipts, from all treatment, transport, storage or
disposal facilities or operators employed by Borrowers in connection with the
transport or disposal of any Hazardous Waste generated at the Real Property.

          (d) In the event any Borrower obtains, gives or receives notice of any
Release or threat of Release of a reportable quantity of any Hazardous
Substances at the Real Property (any such event being hereinafter referred to as
a "Hazardous Discharge") or receives any notice of violation, request for
information or notification that it is potentially responsible for investigation
or cleanup of environmental conditions at the Real Property, demand letter or
complaint, order, citation, or other written notice with regard to any Hazardous
Discharge or violation of Environmental Laws affecting the Real Property or any
Borrower's interest therein (any of the foregoing is referred to herein as an
"Environmental Complaint") from any Person, including any state agency
responsible in whole or in part for environmental matters in the state in which
the Real Property is located or the United States Environmental Protection
Agency (any such person or entity hereinafter the "Authority"), then Borrowing
Agent shall, within five (5) Business Days, give written notice of same to Agent
detailing facts and circumstances of which any Borrower is aware giving rise to
the Hazardous Discharge or Environmental Complaint.  Such information is to be
provided to allow Agent to protect its security interest in the Real Property
and the Collateral and is not intended to create nor shall it create any
obligation upon Agent or any Lender with respect thereto.

          (e) Borrowers shall promptly forward to Agent copies of any request
for information, notification of potential liability, demand letter relating to
potential responsibility with respect to the investigation or cleanup of
Hazardous Substances at any other site owned, operated or used by any Borrower
to dispose of Hazardous Substances and shall continue to forward copies of
correspondence between any Borrower and the Authority regarding such claims to
Agent until the claim is settled.  Borrowers shall promptly forward to Agent
copies of all documents and reports concerning a Hazardous Discharge at the Real
Property that any Borrower is required to file under any Environmental Laws.
Such information is to be provided solely to allow Agent to protect Agent's
security interest in the Real Property and the Collateral.

          (f) Borrowers shall respond promptly to any Hazardous Discharge or
Environmental Complaint and take all necessary action in order to safeguard the
health of any Person and to avoid subjecting the Collateral or Real Property to
any Lien.  If any Borrower shall fail to respond promptly to any Hazardous
Discharge or Environmental Complaint or any Borrower shall fail to comply with
any of the requirements

of any Environmental Laws, Agent on behalf of Lenders may, but without the
obligation to do so, for the sole purpose of protecting Agent's interest in
Collateral: (A) give such notices or (B) enter onto the Real Property (or
authorize third parties to enter onto the Real Property) and take such actions
as Agent (or such third parties as directed by Agent) deems reasonably necessary
or advisable, to clean up, remove, mitigate or otherwise deal with any such
Hazardous Discharge or Environmental Complaint. All reasonable costs and
expenses incurred by Agent and Lenders (or such third parties) in the exercise
of any such rights, including any sums paid in connection with any judicial or
administrative investigation or proceedings, fines and penalties, together with
interest thereon from the date expended at the Default Rate for Domestic Rate
Loans constituting Revolving Advances shall be paid upon demand by Borrowers,
and until paid shall be added to and become a part of the Obligations secured by
the Liens created by the terms of this Agreement or any other agreement between
Agent, any Lender and any Borrower.

          (g) Promptly after any Borrower's discovery of a Hazardous Discharge
or upon the written request of Agent from time to time, Borrowers shall provide
Agent, at Borrowers' expense, with an environmental site assessment or
environmental audit report prepared by an environmental engineering firm
acceptable in the reasonable opinion of Agent, to assess with a reasonable
degree of certainty the existence of a Hazardous Discharge and the potential
costs in connection with abatement, cleanup and removal of any Hazardous
Substances found on, under, at or within the Real Property.  Any report or
investigation of such Hazardous Discharge proposed and acceptable to an
appropriate Authority that is charged to oversee the clean-up of such Hazardous
Discharge shall be acceptable to Agent.  If such estimates, individually or in
the aggregate, exceed $100,000, Agent shall have the right to require Borrowers
to post a bond, letter of credit or other security reasonably satisfactory to
Agent to secure payment of these costs and expenses.

          (h) Borrowers shall defend and indemnify Agent and Lenders and hold
Agent, Lenders and their respective employees, agents, directors and officers
harmless from and against all loss, liability, damage and expense, claims,
costs, fines and penalties, including attorney's fees, suffered or incurred by
Agent or Lenders under or on account of any Environmental Laws, including the
assertion of any Lien thereunder, with respect to any Hazardous Discharge, the
presence of any Hazardous Substances affecting the Real Property, whether or not
the same originates or emerges from the Real Property or any contiguous real
estate, including any loss of value of the Real Property as a result of the
foregoing except to the extent such loss, liability, damage and expense is
attributable to any Hazardous Discharge resulting from actions on the part of
Agent or any Lender.  Borrowers' obligations under this Section 4.19 shall arise
upon the discovery of the presence of any Hazardous Substances at the Real
Property, whether or not any federal, state, or local environmental agency has
taken or threatened any action in connection with the presence of any Hazardous
Substances.  Borrowers' obligation and the indemnifications hereunder shall
survive the termination of this Agreement.

discretion without notice or demand, take the Collateral and remove the same to
such place as Agent may deem advisable and Agent may require Borrowers to make
the Collateral available to Agent at a convenient place.  With or without having
the Collateral at the time or place of sale, Agent may sell the Collateral, or
any part thereof, at public or private sale, at any time or place, in one or

of a type customarily sold on a recognized market, Agent shall give Borrowers
reasonable notification of such sale or sales, it being agreed that in all
events written notice mailed to Borrowers at least five (5) days prior to such
sale or sales is reasonable notification.  At any public sale Agent or any
Lender may bid for and become the purchaser, and Agent, any Lender or any other
purchaser at any such sale thereafter shall hold the Collateral

                                      -59-

expenses incurred by Agent for collection and for acquisition, completion,
protection, removal, storage, sale and delivery of the Collateral; second, to
interest due upon any of the Obligations and any fees payable under this

           ------------------
discretion to determine which rights, Liens, security interests or remedies

TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

SECTION 13.    EFFECTIVE DATE AND TERMINATION.
               -------------------------------

     13.1  Term.  This Agreement, which shall inure to the benefit of and shall
           ----
be binding upon respective successors and permitted assigns of each Borrower,
Agent and each Lender, shall become effective on the date hereof and shall
continue in full force and effect until March 14, 2003 (the "Term") unless
sooner terminated as herein provided.  Borrowers may terminate this Agreement at
any time upon ninety (90) days prior written notice upon payment in full of the
Obligations.  In the event the Obligations are prepaid in full prior to the last
day of the Term (the date of such prepayment hereinafter referred to as the
"Early Termination Date") and the Loan Documents are terminated, Borrowers shall
pay to Agent for the benefit of Lenders an early termination fee in an amount
equal to (x) two percent (2.0%) of the Maximum Revolving Amount if the Early
Termination Date occurs on or after the Closing Date to and including the date
immediately preceding the first anniversary of the Closing Date, and (y) one
percent (1.0%) of the Maximum Revolving Amount if the Early Termination Date
occurs on or after the first anniversary of the Closing Date to and including
the date immediately preceding the second anniversary of the Closing Date, and
(z) one-half percent (0.5%) of the Maximum Revolving Amount if the Early
Termination Date occurs on or after the second anniversary of the Closing Date
to and including the date immediately preceding the third anniversary of the
Closing Date.

     13.2  Termination.  The termination of the Agreement shall not affect any
           -----------
Borrower's, Agent's or any Lender's rights, or any of the Obligations having
their inception prior to the effective date of such termination, and the
provisions hereof shall continue to be fully operative until all transactions
entered into, rights or interests created or Obligations have been fully
disposed of, concluded or liquidated.  The security interests, Liens and rights
granted to Agent and Lenders hereunder and the financing statements filed
hereunder shall continue in full force and effect, notwithstanding the
termination of this Agreement or the fact that Borrowers' Account may from time
to time be temporarily in a zero or credit position, until all of the
Obligations of each Borrower have been paid or performed in full after the
termination of this Agreement or each Borrower has furnished Agent and Lenders
with an indemnification satisfactory to Agent and Lenders with respect thereto.
Accordingly, each Borrower waives any rights which it may have under Section 9-
404(1) of the UCC to demand the filing of termination statements with respect to
the Collateral, and Agent shall not be required to send such termination
statements to each Borrower, or to file them with any filing office, unless and
until this Agreement shall have been terminated in accordance with its terms and
all Obligations paid in full in immediately available funds.  All
representations, warranties, covenants, waivers and agreements contained herein
shall survive termination hereof until all Obligations are paid or performed in
full.

SECTION 14.    REGARDING AGENT.
               ----------------

     14.1  Appointment.  Each Lender hereby designates PNC to act as Agent for
           -----------
such Lender under this Agreement and the Other Documents.  Each Lender hereby
irrevocably authorizes Agent to take such action on its behalf under the
provisions of each of the Loan Documents and to exercise such powers and to
perform such duties hereunder and thereunder as are specifically delegated to or
required of Agent by the terms hereof and thereof and such other powers as are
reasonably incidental thereto and Agent shall hold all Collateral, payments of
principal and interest, fees (except the fees set forth in Sections 3.3(a) and
3.4), charges

                                      -61-
<PAGE>

and collections (without giving effect to any collection days) received pursuant
to this Agreement, for its benefit and the ratable benefit of Lenders. Agent may
perform any of its duties hereunder by or through its agents or employees. As to
any matters not expressly provided for by this Agreement (including collection
of the Notes) Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Required Lenders, and such instructions shall be binding; provided, however,
                                                              --------  -------
that Agent shall not be required to take any action which exposes Agent to
liability or which is contrary to this Agreement or the Other Documents or
Applicable Law unless Agent is furnished with an indemnification reasonably
satisfactory to Agent with respect thereto.

     14.2  Nature of Duties.  Agent shall have no duties or responsibilities
           ----------------
except those expressly set forth in this Agreement and the Other Documents.
Neither Agent nor any of its officers, directors, employees or agents shall be
(i) liable for any action taken or omitted by them as such hereunder or in
connection herewith, unless caused by their gross (not mere) negligence or
willful misconduct, or (ii) responsible in any manner for any recitals,
statements, representations or warranties made by any Borrower or any officer
thereof contained in this Agreement, or in any of the Other Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by Agent under or in connection with, any of the Loan Documents or
for the value, validity, effectiveness, genuineness, enforceability or
sufficiency of any of the Loan Documents or for any failure of any Borrower to
perform its obligations hereunder.  Agent shall not 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, any of the Loan Documents, or
to inspect the properties, books or records of any Borrower.  The duties of
Agent as respects the Advances to Borrowers shall be mechanical and
administrative in nature; Agent shall not have by reason of this Agreement a
fiduciary relationship in respect of any Lender; and nothing in this Agreement,
expressed or implied, is intended to or shall be so construed as to impose upon
Agent any obligations in respect of this Agreement except as expressly set forth
herein.

     14.3  Lack of Reliance on Agent and Resignation.
           -----------------------------------------

          (a) Independently and without reliance upon Agent or any other Lender,
each Lender has made and shall continue to make (i) its own independent
investigation of the financial condition and affairs of each Borrower in
connection with the making and the continuance of the Advances hereunder and the
taking or not taking of any action in connection herewith, and (ii) its own
appraisal of the creditworthiness of each Borrower.  Agent shall have no duty or
responsibility, either initially or on a continuing basis, to provide any Lender
with any credit or other information with respect thereto, whether coming into
its possession before making of the Advances or at any time or times thereafter
except as shall be provided by any Borrower pursuant to the terms hereof.  Agent
shall not be responsible to any Lender for any recitals, statements,
information, representations or warranties herein or in any agreement, document,
certificate or a statement delivered in connection with or for the execution,
effectiveness, genuineness, validity, enforceability, collectibility or
sufficiency of any of the Loan Documents, or of the financial condition of any
Borrower, or be required to make any inquiry concerning either the performance
or observance of any of the terms, provisions or conditions of this Agreement,
the Notes, the Other Documents or the financial condition of any Borrower, or
the existence of any Event of Default or any Default.

          (b) Agent may resign on sixty (60) days written notice to each of
Lenders and Borrowing Agent and upon such resignation, the Required Lenders will
promptly designate a successor Agent reasonably satisfactory to Borrowers.  Any
such successor Agent shall succeed to the rights, powers and duties of Agent,
and the term "Agent" shall mean such successor agent effective upon its
appointment, and the former Agent's

                                      -62-
<PAGE>

rights, powers and duties as Agent shall be terminated, without any other or
further act or deed on the part of such former Agent. After any Agent's
resignation 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.

     14.4  Certain Rights of Agent.  If Agent shall request instructions from
           -----------------------
Lenders with respect to any act or action (including failure to act) in
connection with this Agreement or any Other Document, Agent shall be entitled to
refrain from such act or taking such action unless and until Agent shall have
received instructions from the Required Lenders; and Agent shall not incur
liability to any Person by reason of so refraining.  Without limiting the
foregoing, Lenders shall not have any right of action whatsoever against Agent
as a result of its acting or refraining from acting hereunder in accordance with
the instructions of the Required Lenders.

     14.5  Reliance.  Agent shall be entitled to rely, and shall be fully
           --------
protected in relying, upon any note, writing, resolution, notice, statement,
certificate, telex, teletype or telecopier message, cablegram, order or other
document or telephone message believed by it to be genuine and correct and to
have been signed, sent or made by the proper person or entity, and, with respect
to all legal matters pertaining to this Agreement and the Other Documents and
its duties hereunder, upon advice of counsel selected by it.  Agent may employ
agents and attorneys-in-fact and shall not be liable for the default or
misconduct of any such agents or attorneys-in-fact selected by Agent with
reasonable care.

     14.6  Notice of Default.  Agent shall not be deemed to have knowledge or
           -----------------
notice of the occurrence of any Default or Event of Default hereunder or under
the Other Documents, unless Agent has received notice from a Lender or a
Borrower referring to this Agreement or the Other Documents, describing such
Default or Event of Default and stating that such notice is a "notice of
default."  In the event that Agent receives such a notice, Agent shall give
notice thereof to Lenders.  Agent shall take such action with respect to such
Default or Event of Default as shall be reasonably directed by the Required
Lenders; provided, however, that, unless and until Agent shall have received
         --------  -------
such directions, 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 in the best interests of Lenders.

     14.7  Indemnification.  To the extent Agent is not reimbursed and
           ---------------
indemnified by Borrowers, each Lender will reimburse and indemnify Agent in
proportion to its respective portion of the Advances (or, if no Advances are
outstanding, according to its Commitment Percentage), from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by or asserted against Agent in performing its
duties hereunder, or in any way relating to or arising out of this Agreement or
any Other Document; provided, however, that, Lenders shall not be liable for any
                    --------  -------
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from Agent's gross
(not mere) negligence or willful misconduct.

     14.8  Agent in its Individual Capacity.  With respect to the obligation of
           --------------------------------
Agent to lend under this Agreement, the Advances made by it shall have the same
rights and powers hereunder as any other Lender and as if it were not performing
the duties as Agent specified herein; and the term "Lender" or any similar term
shall, unless the context clearly otherwise indicates, include Agent in its
individual capacity as a Lender.  Agent may engage in business with any Borrower
as if it were not performing the duties specified herein, and may accept fees
and other consideration from any Borrower for services in connection with this
Agreement or otherwise without having to account for the same to Lenders.

                                      -63-
<PAGE>

     14.9  Delivery of Documents.  To the extent Agent receives financial
           ---------------------
statements required under Sections 9.7, 9.8, and 9.9 from any Borrower pursuant
to the terms of this Agreement, Agent will promptly furnish such documents and
information to Lenders.

     14.10  Borrowers' Undertaking to Agent.  Without prejudice to their
            -------------------------------
respective obligations to Lenders under the other provisions of this Agreement,
each Borrower hereby undertakes with Agent to pay to Agent from time to time on
demand all amounts from time to time due and payable by it for the account of
Agent or Lenders or any of them pursuant to this Agreement to the extent not
already paid.  Any payment made pursuant to any such demand shall pro tanto
satisfy the relevant Borrower's obligations to make payments for the account of
Lenders or the relevant one or more of them pursuant to this Agreement.

SECTION 15.    CO-BORROWER PROVISIONS.
               -----------------------

     15.1  Borrowing Agency Provisions.
           ---------------------------

          (a) Each Borrower hereby irrevocably designates Borrowing Agent to be
its attorney and agent and in such capacity to borrow, sign and endorse notes,
and execute and deliver all instruments, documents, writings and further
assurances now or hereafter required hereunder, on behalf of such Borrower or
Borrowers, and hereby authorizes Agent to pay over or credit all loan proceeds
hereunder in accordance with the request of Borrowing Agent.

          (b) The handling of this credit facility as a co-borrowing facility
with a borrowing agent in the manner set forth in this Agreement is solely as an
accommodation to Borrowers and at their request, and neither Agent nor any
Lender shall incur any liability to any Borrower as a result thereof.  In order
to utilize the financial powers of each Borrower in the most efficient and
economical manner, and in order to facilitate the financing of each Borrower's
needs, Lenders will, at the request of the Borrowing Agent, make Advances and
other financial accommodations to all Borrowers on a combined basis and in
accordance with the provisions set forth in this Agreement.  Borrowers
acknowledge that their business is a mutual and collective enterprise and
Borrowers believe that the consolidation of all Advances and other financial
accommodations under this Agreement will enhance the aggregate borrowing powers
of each Borrower and ease the administration of their loan relationship with
Lenders, all to the mutual advantage of Borrowers. Agent's and Lenders'
willingness to extend credit to Borrowers pursuant to the terms hereof and to
administer each Borrower's portion of the Collateral therefor, on a combined
basis as more fully set forth in this Agreement, is done solely as an
accommodation to Borrowers, at their request and in furtherance of their mutual
and collective enterprise. To induce Agent and Lenders to do so and in
consideration thereof, each Borrower hereby indemnifies Agent and each Lender
and holds Agent and each Lender harmless from and against any and all
liabilities, expenses, losses, damages and claims of damage or injury asserted
against Agent or any Lender by any Person arising from or incurred by reason of
the handling of the financing arrangements of Borrowers as provided herein,
reliance by Agent or any Lender on any request or instruction from Borrowing
Agent or any other action taken by Agent or any Lender with respect to this
Section 15.1 except due to willful misconduct or gross (not mere) negligence by
the indemnified party.

          (c) All Obligations shall be joint and several, and each Borrower
shall make payment upon the maturity of the Obligations by acceleration or
otherwise, and such obligation and liability on the part of each Borrower shall
in no way be affected by any extensions, renewals and forbearance granted to
Agent or any Lender to any Borrower, failure of Agent or any Lender to give any
Borrower notice of borrowing or

                                      -64-
<PAGE>

any other notice, any failure of Agent or any Lender to pursue or preserve its
rights against any Borrower, the release by Agent or any Lender of any
Collateral now or thereafter acquired from any Borrower, and such agreement by
each Borrower to pay upon any notice issued pursuant thereto is unconditional
and unaffected by prior recourse by Agent or any Lender to the other Borrowers
or any Collateral for such Borrower's Obligations or the lack thereof.

          (d) Each Borrower's joint and several liability hereunder with respect
to the Advances and other Obligations shall, to the fullest extent permitted by
Applicable Law, be unconditional irrespective of (i) the validity,
enforceability, avoidance or subordination of any of the Obligations or of any
promissory note or other document evidencing all or any part of the Obligations,
(ii) the absence of any attempt to collect any of the Obligations from any other
Borrower or Guarantor or any Collateral or 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 Agent or any Lender with
respect to any of the Obligations or any instrument or agreement evidencing or
securing the payment of any of the Obligations, or any other agreement now or
hereafter executed by any other Borrower and delivered to Agent or any Lender,
(iv) the failure by Lender to take any steps to perfect or maintain the
perfected status of its security interest in or Lien upon, or to preserve its
rights to, any of the Collateral or other security for the payment or
performance of any of the Obligations, or Agent's or any Lender's release of any
Collateral or of its Liens upon any Collateral, (v) Agent's or any Lenders'
election, in any proceeding instituted under the Bankruptcy Code, for the
application of Section 1111(b)(2) of the Bankruptcy Code, (vi) any borrowing or
grant of a security interest by any other Borrower, as debtor-in-possession
under Section 364 of the Bankruptcy Code, (vii) the release or compromise, in
whole or in part, of the liability of any Borrower or Guarantor for the payment
of any of the Obligations, (viii) any amendment or modification of any of the
Loan Documents or waiver of any Default or Event of Default thereunder, (ix) any
increase in the amount of the Obligations beyond any limits imposed herein or in
the amount of any interest, fees or other charges payable in connection
therewith, or any decrease in the same, (x) the disallowance of all or any
portion of Lender's claims for the repayment of any of the Obligations under
Section 502 of the Bankruptcy Code, or (xi) any other circumstance that might
constitute a legal or equitable discharge or defense of any Borrower and
Guarantor.  At any time an Event of Default exists, Lender may proceed directly
and at once, without notice to any Borrower or Guarantor, against any or all of
Borrowers or Guarantors to collect and recover all or any part of the
Obligations, without first proceeding against any other Borrower or Guarantor or
against any Collateral or other security for the payment or performance of any
of the Obligations, and each Borrower waives any provision that might otherwise
require Agent or any Lender under Applicable Law to pursue or exhaust its
remedies against any Collateral or any other Borrower or Guarantor before
pursuing such Borrower.  Each Borrower consents and agrees that Agent and any
Lender shall be under no obligation to marshall any assets in favor of any
Borrower or Guarantor or against or in payment of any or all of the Obligations.

          (e) Each Borrower is unconditionally obligated to repay the
Obligations as a joint and several obligor under this Agreement.  If, as of any
date, the aggregate amount of payments made by a Borrower on account of the
Obligations and proceeds of such Borrower's Collateral that are applied to the
Obligations exceeds the aggregate amount of Advances actually used by such
Borrower in its business (such excess amount being referred to as an
"Accommodation Payment"), then each of the other Borrowers shall be obligated to
make contribution to such Borrower (the "Paying Borrower") in an amount equal to
(A) the product derived by multiplying the sum of each Accommodation Payment of
each Borrower by the Allocable Percentage of the Borrower from whom contribution
is sought minus (B) the amount, if any, of the then outstanding Accommodation
          -----
Payment of such Contributing Borrower (such last mentioned amount which is to be
subtracted from the aforesaid product to be increased by any amounts theretofore
paid by such

                                      -65-
<PAGE>

Contributing Borrower by way of contribution hereunder, and to be decreased by
any amounts theretofore received by such Contributing Borrower by way of
contribution hereunder); provided, however, that a Paying Borrower's recovery
                         --------  -------
of contribution hereunder from the other Borrowers shall be limited to that
amount paid by the Paying Borrower in excess of its Allocable Percentage of
all Accommodation Payments then outstanding of all Borrowers.  As used herein,
the term "Allocable Percentage" shall mean, on any date of determinations
thereof, a fraction the denominator of which shall be equal to the number of
Borrowers who are parties to this Agreement on such date and the numerator of
which shall be 1; provided, however, that such percentages shall be modified in
                  --------  -------
the event that contribution from a Borrower is not possible by reason of
insolvency, bankruptcy or otherwise by reducing such Borrower's Allocable
Percentage equitably and by adjusting the Allocable Percentage of the other
Borrowers proportionately so that the Allocable Percentages of all Borrowers at
all times equals 100%.

     15.2  Subordination.  Each Borrower expressly subordinates and postpones
           -------------
the exercise of any and all rights of subrogation, reimbursement, indemnity,
exoneration, contribution of any other claim that such Borrower may now or
hereafter have against the other Borrowers or other Person directly or
contingently liable for the Obligations hereunder, or against or with respect to
the other Borrowers' property (including any property which is Collateral for
the Obligations), arising from the existence or performance of this Agreement,
until termination of this Agreement and repayment in full of the Obligations.

SECTION 16.    MISCELLANEOUS.
               --------------

     16.1  Governing Law; Process.  This Agreement shall be governed by and
           ----------------------
construed in accordance with the laws of the State of Georgia applied to
contracts to be performed wholly within the State of Georgia.  Any judicial
proceeding brought by or against any Borrower with respect to any of the
Obligations, this Agreement or any related agreement may be brought in any court
of competent jurisdiction in the State of Georgia, United States of America,
and, by execution and delivery of this Agreement, each Borrower accepts for
itself and in connection with its properties, generally and unconditionally, the
non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be
bound by any judgment rendered thereby in connection with this Agreement.  Each
Borrower hereby waives personal service of any and all process upon it and
consents that all such service of process may be made by registered mail (return
receipt requested) directed to Borrowing Agent at its address set forth in
Section 16.6 and service so made shall be deemed completed five (5) days after
the same shall have been so deposited in the mails of the United States of
America, or, at the Agent's and/or any Lender's option, by service upon
Borrowing Agent which each Borrower irrevocably appoints as such Borrower's
agent for the purpose of accepting service within the State of Georgia.  Nothing
herein shall affect the right to serve process in any manner permitted by
Applicable Law or shall limit the right of Agent or any Lender to bring
proceedings against any Borrower in the courts of any other jurisdiction.  Each
Borrower waives any objection to jurisdiction and venue of any action instituted
hereunder and shall not assert any defense based on lack of jurisdiction or
venue or based upon forum non conveniens.  Any judicial proceeding by any
Borrower against Agent or any Lender involving, directly or indirectly, any
matter or claim in any way arising out of, related to or connected with this
Agreement or any related agreement, shall be brought only in a federal or state
court located in the County of Cobb, State of Georgia.

     16.2  Entire Understanding.
           --------------------

          (a) This Agreement and the documents executed concurrently herewith
contain the entire understanding between each Borrower, Agent and each Lender
and supersedes all prior agreements and understandings, if any, relating to the
subject matter hereof.  Any promises, representations, warranties or

                                      -66-
<PAGE>

guarantees not herein contained and hereinafter made shall have no force and
effect unless in writing, signed by each Borrower's, Agent's and each Lender's
respective officers. Neither this Agreement nor any portion or provisions hereof
may be changed, modified, amended, waived, supplemented, discharged, cancelled
or terminated orally or by any course of dealing, or in any manner other than by
an agreement in writing, signed by the party to be charged. Each Borrower
acknowledges that it has been advised by counsel in connection with the
execution of this Agreement and Other Documents and is not relying upon oral
representations or statements inconsistent with the terms and provisions of this
Agreement.

          (b) The Required Lenders, Agent with the consent in writing of the
Required Lenders, and Borrowers may, subject to the provisions of this Section
16.2(b), from time to time enter into written supplemental agreements to this
Agreement or any of the Other Documents executed by Borrowers, for the purpose
of adding or deleting any provisions or otherwise changing, varying or waiving
in any manner the rights of Lenders, Agent or Borrowers thereunder or the
conditions, provisions or terms thereof of waiving any covenant, obligation or
Event of Default thereunder, but only to the extent specified in such written
agreements; provided, however, that no such supplemental agreement shall,
without the consent of all Lenders:

               (i) increase the Commitment Percentage or maximum dollar
     commitment of any Lender;

               (ii)  extend the maturity of any Note or the due date for any
     amount payable hereunder, or decrease the rate of interest or reduce any
     fee payable by Borrowers to Lenders pursuant to this Agreement;

               (iii)  alter the definition of the term Required Lenders or
     alter, amend or modify this Section 16.2(b);

               (iv)  release any Collateral during any calendar year (other than
     in accordance with the provisions of this Agreement) having an aggregate
     value in excess of $500,000;

               (v) change the rights and duties of Agent;

               (vi)  permit any Out-of-Formula Loan to be made if after giving
     effect thereto the total of Revolving Advances outstanding hereunder would
     exceed the Formula Amount for more than sixty (60) consecutive Business
     Days or exceed $1,000,000; or

               (vii)  increase the Advance Rate above the Advance Rate in effect
     on the Closing Date.

Any such supplemental agreement shall apply equally to each Lender and shall be
binding upon Borrowers, Lenders and Agent and all future holders of the
Obligations.  In the case of any waiver, Borrowers, Agent and Lenders shall be
restored to their former positions and rights, and any Event of Default waived
shall be deemed to be cured and not continuing, but no waiver of a specific
Event of Default shall extend to any subsequent Event of Default (whether or not
the subsequent Event of Default is the same as the Event of Default which was
waived), or impair any right consequent thereon.

     In the event that Agent requests the consent of a Lender pursuant to this
Section 16.2 and such Lender shall not respond or reply to Agent in writing
within five (5) Business Days of delivery of such request, such

                                      -67-
<PAGE>

Lender shall be deemed to have consented to matter that was the subject of the
request. In the event that Agent requests the consent of a Lender pursuant to
this Section 16.2 and such consent is denied, then PNC may, at its option,
require such Lender to assign its interest in the Advances to PNC or to another
Lender or to any other Person designated by the Agent (the "Designated Lender"),
for a price equal to the then outstanding principal amount thereof plus accrued
and unpaid interest and fees due such Lender, which interest and fees shall be
paid when collected from Borrower. In the event PNC elects to require any Lender
to assign its interest to PNC or to the Designated Lender, PNC will so notify
such Lender in writing within forty-five (45) days following such Lender's
denial, and such Lender will assign its interest to PNC or the Designated Lender
no later than five (5) days following receipt of such notice pursuant to a
Commitment Transfer Supplement executed by such Lender, PNC or the Designated
Lender, as appropriate, and Agent.

     16.3  Successors and Assigns; Participations; New Lenders.
           ---------------------------------------------------

          (a) This Agreement shall be binding upon and inure to the benefit of
Borrowers, Agent, each Lender, all future holders of the Obligations and their
respective successors and assigns, except that no Borrower may assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of Agent and each Lender.

          (b) Each Borrower acknowledges that in the regular course of
commercial banking business one or more Lenders may at any time and from time to
time sell participating interests in the Advances to other financial
institutions (each such transferee or purchaser of a participating interest, a
"Participant").  Each Participant may exercise all rights of payment (including
rights of set-off) with respect to the portion of such Advances held by it or
other Obligations payable hereunder as fully as if such Participant were the
direct holder thereof provided that Borrowers shall not be required to pay to
any Participant more than the amount which it would have been required to pay to
Lender which granted an interest in its Advances or other Obligations payable
hereunder to such Participant had such Lender retained such interest in the
Advances hereunder or other Obligations payable hereunder and in no event shall
Borrowers be required to pay any such amount arising from the same circumstances
and with respect to the same Advances or other Obligations payable hereunder to
both such Lender and such Participant.  Each Borrower hereby grants to any
Participant a continuing security interest in any deposits, moneys or other
property actually or constructively held by such Participant as security for the
Participant's interest in the Advances.

          (c) Any Lender may with the consent of Agent (which shall not be
unreasonably withheld or delayed) sell, assign or transfer all or any part of
its rights under the Loan Documents to one or more additional banks or financial
institutions (each a "Purchasing Lender"), and one or more Purchasing Lenders
may commit to make Advances hereunder, in minimum amounts of not less than
$5,000,000, pursuant to a Commitment Transfer Supplement, executed by an
Purchasing Lender, the transferor Lender, and Agent and delivered to Agent for
recording.  Upon such execution, delivery, acceptance and recording, from and
after the transfer effective date determined pursuant to such Commitment
Transfer Supplement, (i) Purchasing Lender thereunder shall be a party hereto
and, to the extent provided in such Commitment Transfer Supplement, have the
rights and obligations of a Lender thereunder with a Commitment Percentage as
set forth therein, and (ii) the transferor Lender thereunder shall, to the
extent provided in such Commitment Transfer Supplement, be released from its
obligations under this Agreement, the Commitment Transfer Supplement creating a
novation for that purpose.  Such Commitment Transfer Supplement shall be deemed
to amend this Agreement to the extent, and only to the extent, necessary to
reflect the addition of such Purchasing Lender and the resulting adjustment of
the Commitment Percentages arising from the purchase by such Purchasing Lender
of all or a portion of the rights and obligations of such transferor Lender
under this Agreement and the Other Documents.

                                      -68-
<PAGE>

Borrowers hereby consent to the addition of such Purchasing Lender and the
resulting adjustment of the Commitment Percentages arising from the purchase by
such Purchasing Lender of all or a portion of the rights and obligations of such
transferor Lender under this Agreement and the Other Documents. Borrowers shall
execute and deliver such further documents and do such further reasonable acts
and things in order to effectuate the foregoing.

          (d) Agent shall maintain at its address a copy of each Commitment
Transfer Supplement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Advances owing to each Lender from
time to time.  The entries in the Register shall be conclusive, in the absence
of manifest error, and Borrowers, Agent and Lenders may treat each Person whose
name is recorded in the Register as the owner of the Advance recorded therein
for the purposes of this Agreement.  The Register shall be available for
inspection by Borrowers or any Lender at any reasonable time and from time to
time upon reasonable prior notice.  Agent shall receive a fee in the amount of
$3,500 payable by the applicable Purchasing Lender upon the effective date of
each transfer or assignment to such Purchasing Lender.

          (e) Borrowers authorize each Lender to disclose to any Participant or
Purchasing Lender and any prospective Participant or Purchasing Lender any and
all financial information in such Lender's possession concerning Borrowers which
has been delivered to such Lender by or on behalf of Borrowers pursuant to this
Agreement or in connection with such Lender's credit evaluation of Borrowers.

     16.4  Application of Payments.  Agent shall have the continuing and
           -----------------------
exclusive right to apply or reverse and re-apply any payment and any and all
proceeds of Collateral to any portion of the Obligations. To the extent that any
Borrower makes a payment or Agent or any Lender receives any payment or proceeds
of the Collateral for any Borrower's benefit, which are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required to
be repaid to a trustee, debtor in possession, receiver, custodian or any other
party under any bankruptcy law, common law or equitable cause, then, to such
extent, the Obligations or part thereof intended to be satisfied shall be
revived and continue as if such payment or proceeds had not been received by
Agent or such Lender.

     16.5  Indemnity.  Each Borrower shall indemnify Agent, each Lender and each
           ---------
of their respective officers, directors, Affiliates, employees and agents from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind or
nature whatsoever (including fees and disbursements of counsel) which may be
imposed on, incurred by, or asserted against Agent or any Lender in any
litigation, proceeding or investigation instituted or conducted by any
Governmental Body or any other Person with respect to any aspect of, or any
transaction contemplated by, or referred to in, or any matter related to, any of
the Loan Documents, whether or not Agent or any Lender is a party thereto,
except to the extent that any of the foregoing arises out of the willful
misconduct or gross negligence of the party being indemnified.

     16.6  Notice.  Any notice or request hereunder may be given to any Borrower
           ------
or to Agent or any Lender at their respective addresses set forth below or at
such other address as may hereafter be specified in a notice designated as a
notice of change of address under this Section.  Any notice or request hereunder

Other Documents and payment in full of the Obligations.

     16.8  Severability.  If any part of this Agreement is contrary to,
           ------------
prohibited by, or deemed invalid under Applicable Laws or regulations, such
provision shall be inapplicable and deemed omitted to the extent so contrary,

Borrower that was not in existence on the Closing Date is required, if so
requested by Agent, to become a party to and be bound by all of the terms of the
Loan Agreement and the other Loan Documents as if such Subsidiary had been an
original signatory and party to the Loan Agreement and Other Documents to which
the Existing Borrowers are parties.  The undersigned, _______________________, a
_____________________ corporation ("New Borrower") is a wholly-owned Subsidiary
of _________________________ and is executing this Joinder Agreement, at Agent's
request and with Agent's consent, in accordance with the requirements of the
Loan Agreement, in order to induce Agent and Lenders to continue extending
credit to or for the benefit of the Existing Borrowers as well as New Borrower
based upon not only the Eligible Receivables and Eligible Inventory of the
Existing Borrowers but also the Eligible Receivables and Eligible Inventory of
New Borrower.

     NOW, THEREFORE, for Ten Dollars ($10.00) in hand paid and other good and
valuable consideration, receipt whereof is severally acknowledged, the parties
hereto, intending to be legally bound hereby, agree as follows:

                              Exhibit C - Page 1
<PAGE>

     1.   By its signature below, New Borrower hereby agrees that it is a
"Borrower" under and bound by and subject to all of the provisions of the Loan
Agreement and Other Documents to which the Existing Borrowers are parties, with
the same force and effect as if New Borrower were an original signatory thereto,
and New Borrower hereby agrees to abide by and perform all of its obligations as
a "Borrower" under the Loan Agreement and the Other Documents.  Each reference
to "Borrowers" in the Loan Agreement and other Loan Documents shall be
understood to mean and include New Borrower as well as the Existing Borrowers.
The terms of the Loan Agreement are hereby incorporated into this Joinder
Agreement by reference.

     2.   New Borrower acknowledges and agrees that it is and shall be jointly
and severally liable with the Existing Borrowers for all Revolving Advances and
other Obligations outstanding on the date hereof and shall be jointly and
severally liable with all Existing Borrowers (together with each other Person
who becomes a Borrower on or after the date hereof) for all Revolving Advances
and other Obligations at any time or times outstanding hereafter.  New Borrower
hereby appoints and designates Borrowing Agent as its representative for all
purposes under the Loan Agreement, including the making of requests for
Revolving Advances and other extensions of credit pursuant to the terms of the
Loan Agreement and receiving notices and other communications to Borrowers from
Agent or any Lenders.

     3.   To secure the prompt payment and performance to Agent and Lenders of
all of the Obligations, New Borrower hereby grants to Agent, for the benefit of
Agent and for the ratable benefit of Lenders, a continuing security interest in
and Lien upon all of New Borrower's assets that are included within the
definition of "Collateral" under the Loan Agreement and any of the Other

requested by Agent.

     4.   New Borrower represents and warrants to Agent and Lenders that New
Borrower is a wholly-owned Subsidiary of _____________________________ and is
engaged in substantially the same business as the Existing Borrowers and
operates with the Existing Borrowers in a joint and common enterprise; this
Joinder Agreement has been duly authorized, executed and delivered by New
Borrower and constitutes a legal, valid and binding obligation of New Borrower
enforceable against it in accordance with its terms, except as enforceability
thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting creditors' rights generally and by general
principles of equity (regardless of whether such enforceability is considered in
a proceeding at law or in equity); and the Schedules annexed hereto contain
true, accurate and complete information with respect to New Borrower and the
matters covered by the provisions of Section 5 of the Loan Agreement and such
Schedules shall be deemed to supplement and become a part of the Schedules
annexed to the Loan Agreement.

     5.   Except as otherwise expressly provided in this Joinder Agreement,
nothing herein shall be deemed to amend or modify any provision of any of the
Loan Documents, each of which shall remain in full force and effect.  This
Joinder Agreement is not intended to be, nor shall it be construed to create, a
novation or accord and satisfaction.  If any provision in or obligation under
this Joinder Agreement shall be invalid, illegal or otherwise unenforceable in
any jurisdiction, then the validity, legality and enforceability of the
remaining provisions or obligations shall not in any way be affected or impaired
thereby.

     6.   New Borrower, jointly and severally with the Existing Borrowers,
agrees to reimburse Agent and Lenders for their respective out-of-pocket
expenses in connection with the preparation, execution and delivery of this
Joinder Agreement, including the fees, disbursements and other charges of
counsel for Agent and Lenders.

instruments, agreements and certificates executed by the parties in connection
therewith or with reference thereto, embody the entire understanding and
agreement among the parties with respect to the subject matter thereof.  Each of
the Schedules as attached hereto is incorporated into this Joinder Agreement and
by this reference made a part hereof and a part of the Loan Agreement.

     8.   This Joinder Agreement may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all of such counterparts
shall constitute but one and the same instrument.

     9.   This Joinder Agreement shall be effective when accepted by Agent (New
Borrower hereby waiving notice of such acceptance) and thereupon shall be deemed
to be a contract governed by and construed and enforced in accordance with the
internal laws of the State of Georgia.

     IN WITNESS WHEREOF, New Borrower and Agent have duly executed this Joinder
Agreement, under seal as of the day and year first written above.

                                    NEW BORROWER:
