Amount". The Revolving Advances of each Lender shall be evidenced by a secured
promissory note ("Revolving Credit Note") substantially in the form attached
hereto as Exhibit 2.1(a).

                  (b) Discretionary Rights. The Advance Rates may be increased
or decreased by Agent at any time and from time to time in the exercise of its
reasonable discretion based upon such credit and collateral considerations
related to the Eligible Receivables or Eligible Inventory, as the case may be,
as Agent reasonably deems appropriate. Each Borrower consents to any such
increases or decreases and acknowledges that decreasing the Advance Rates or
increasing the reserves may limit or restrict Advances requested by Borrowing
Agent. Agent shall give Borrowing Agent five (5) days prior written notice of
its intention to decrease the Advance Rates with an explanation of the basis for
such reductions.

         2.2. Procedure for Revolving Advances Borrowing.

                  (a) 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. If such Revolving Advance is to be an
Equipment Advance, such designation shall be made on the request and such
request shall be accompanied by sales invoices for (or other evidence of the
purchase of) the equipment in respect of which the requested Equipment Advance
is to be made, provided, however, that each Equipment Advance shall be in a
minimum amount of $500,000 and shall not exceed 80% of the acquisition cost of
the equipment being purchased from the proceeds of such Equipment Advance as
approved by the Agent, and, provided, further, that the aggregate principal
amount of all Equipment Advances made hereunder shall not exceed $3,500,000.
Should any amount required to be paid as interest hereunder, 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.

                  (b) Notwithstanding the provisions of (a) 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 an integral multiple of $1,000,000, 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

 
                                      -17-

<PAGE>   24


made available to any Borrower during the continuance of a Default or an Event
of Default.

                  (c) 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 (b)(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 2.2(b) or by its notice of conversion given to Agent pursuant to Section
2.2(d), 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 Base Rate Loan subject
to Section 2.2(d) hereinbelow.

                  (d) Provided that no Event of Default shall have occurred and
be continuing, any Borrower 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 Base 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
a Borrower desires to convert a loan, Borrowing Agent shall give Agent not less
than three (3) Business Days' prior written notice to convert from a Base 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 Base Rate Loan, specifying the date of
such conversion, the loans to be converted and if the conversion is from a Base
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 six (6) Eurodollar Rate Loans, in the aggregate.

                  (e) At its option and upon three (3) Business Days' prior
written notice, any Borrower may prepay the Eurodollar Rate Loans in whole at
any time or in part from time to time, without premium or penalty, but with
accrued interest on the principal being prepaid to the date of such repayment.
Such Borrower shall specify the date of prepayment of Advances which are
Eurodollar Rate Loans and the amount of such prepayment. In the event that any
prepayment of a Eurodollar Rate Loan is required or permitted on a date other
than the last Business Day of the then current Interest Period with respect
thereto, such Borrower shall indemnify Agent and Lenders therefor in accordance
with Section 2.2(f) hereof.

<PAGE>   25



                  (f) Each Borrower shall 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 any Borrower in the payment of the principal of
or interest on any Eurodollar Rate Loan or failure by any Borrower to complete a
borrowing of, a prepayment of or conversion of or to a Eurodollar Rate Loan
after notice thereof has been given, including, but not limited to, 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 as to any
additional amounts payable pursuant to the foregoing sentence submitted by Agent
or any Lender to Borrowing Agent shall be conclusive absent manifest error.

                  (g) 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 cancelled 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 (but not limited to) 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 as to any additional amounts payable
pursuant to the foregoing sentence submitted by Lenders to Borrowing Agent shall
be conclusive absent manifest error.

         2.3. 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 2.2(a) hereof shall, with respect to
requested Revolving Advances to the extent Lenders make such Revolving Advances,
be made available to the applicable Borrower on the day so requested by way of
credit to such Borrower's 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

 
                                      -19-

<PAGE>   26



have been requested by any Borrower, be disbursed to Agent to be applied to the
outstanding Obligations giving rise to such deemed request.

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

         2.5. Repayment of Advances.

                  (a) The Revolving Advances 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 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 which is
unsatisfactory to Agent in its reasonable discretion 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 related agreements shall be made to Agent
at the Payment Office not later than 1:00 P.M. (New York Time) on the due date
therefor in lawful money of the United States of America in federal funds or
other funds immediately available to Agent. Agent 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 2.2
hereof.

                  (d) Borrowers shall pay principal, interest, and all other
amounts payable hereunder, or under any related agreement, without any deduction
whatsoever, including, but not limited to, any deduction for any setoff or
counterclaim.

         2.6. 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.

         2.7. Statement of Account. Agent shall maintain, in accordance with its
customary procedures, a loan account ("Borrowers' Account") in the name of
Borrowers

 
                                      -20-

<PAGE>   27



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

         2.8. Letters of Credit. Subject to the terms and conditions hereof,
Agent shall issue or cause the issuance of 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 would 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 outstanding Letters of Credit shall not exceed
$3,000,000 in the aggregate at any time. 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 Base Rate Loans; Letters of Credit
that have not been drawn upon shall not bear interest.

         2.9. 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 six (6) months after such Letter of Credit's date of issuance and in
no event later than the last day of the Term. Each Letter

 
                                      -21-

<PAGE>   28



of Credit shall be subject to the International Standby Practices 1998 (ISP98)
published by the Institute of International Banking Law & Practice Inc. and any
amendments or revision thereof adhered to by the Issuer and, to the extent not
inconsistent therewith, the laws of the Commonwealth of Pennsylvania.


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

         2.10. 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, without
limitation, 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' gross
negligence or willful misconduct.

                  (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, or the application 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

 
                                      -22-

<PAGE>   29



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 gross negligence or 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 the Maximum Revolving Advance Amount
or 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 Credit
issued hereunder remains outstanding and uncancelled or (C) all Persons (other
than the applicable Borrower) have been fully reimbursed for all payments made
under or relating to Letters of Credit.

         2.11. 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, without limitation, 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 and added to the
Obligations.

         2.12. Manner of Borrowing and Payment.

                  (a) Each borrowing of Revolving Advances shall be advanced
according to the applicable 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

 
                                      -23-

<PAGE>   30



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., New York time, in
Dollars and in immediately available funds.

                  (c) (i) Notwithstanding anything to the contrary contained in
Sections 2.12(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., New York time, 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 its applicable
Commitment Percentage of the difference between (y) such repayments and (z) such
Revolving Advances.

                           (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 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

 
                                      -24-

<PAGE>   31



Lender's Advances may exercise all rights of payment (including, without
limitation, 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.

         2.13. Use of Proceeds. Borrowers shall apply the proceeds of Advances
to (i) repay existing indebtedness owed to NationsBank, N.A., (ii) pay fees and
expenses relating to this transaction, and (iii) to provide for their working
capital needs.

         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 2.14 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

 
                                      -25-

<PAGE>   32



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 2.14,
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 2.14 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.


III.     INTEREST AND FEES.

         3.1. Interest. Interest on Advances shall be payable in arrears on the
last day of each month with respect to Base 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 months, at the earlier of
(a) each three 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 the applicable
Revolving Interest Rate. Whenever, subsequent to the date of this Agreement, the
Base Rate is increased or decreased, the Revolving Interest Rate for Base Rate
Loans shall be similarly changed without notice or demand of any kind by an
amount equal to the

 
                                      -26-

<PAGE>   33



amount of such change in the 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 Base Rate Loans plus two (2%)
percent per annum and (ii) Eurodollar Rate Loans shall bear interest at the
Revolving Interest Rate for Eurodollar Rate Loans plus two (2%) percent per
annum (as applicable, the "Default Rate").

         3.2. Letter of Credit Fees.

                  (a) 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 one and one-half percent (1 1/2%) 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, without limitation, 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
and Acceptance 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 and Acceptance 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.

                  On demand, 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

 
                                      -27-

<PAGE>   34



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.

         3.3. (a) Closing Fee. Upon the execution of this Agreement, Borrowers
shall pay to Agent for the ratable benefit of Lenders a closing fee of $135,000
less that portion of the commitment fee of $90,000 heretofore paid by Borrowers
to Agent remaining after application of such fee to out of pocket expenses.

                  (b) Facility Fee. If, for any quarter during the Term, the
average daily unpaid balance of the Advances for each day of such quarter 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 (.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 in arrears on the last day of each quarter.

         3.4. (a) Collateral Management Fee. Borrowers shall pay Agent a
collateral management 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 management 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) Collateral Monitoring Fee. 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 reasonably determined by
Agent and which monitoring is undertaken by Agent or for Agent's benefit - a
collateral monitoring fee in an amount equal to $675 per day for each person
employed to perform such monitoring plus all costs and disbursements incurred by
Agent in the performance of such examination or analysis. Prior to the
occurrence of a Default or Event of Default, Borrowers shall not be liable to
pay the cost of more than four such collateral audits in any twelve month
period.

         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 Base 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 law. In the
event interest

 
                                      -28-

<PAGE>   35



and other charges as computed hereunder would otherwise exceed the highest rate
permitted under 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.

         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 (without limitation) 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, as the case may be. Agent or such Lender shall certify the
amount of such additional cost or reduced amount to Borrowers, and such
certification shall be conclusive absent manifest error. Each Lender agrees
that, as promptly as practicable after it becomes aware of any circumstances
referred to in this Section 3.7 which would result in any increased cost to

 
                                      -29-

<PAGE>   36



such Lender, such Lender shall (i) to the extent not inconsistent with such
Lender's internal policies of general application, use reasonable commercial
efforts to minimize costs and expenses incurred by it and payable to it by
Borrowers pursuant to this Section 3.7, and (ii) notify Agent and Borrowing
Agent thereof; provided that the failure to give such prompt notice shall not
result in any liability to such Lender and shall not affect the rights of such
Lender, or the obligations of Borrower hereunder; provided further that Borrower
shall not be obligated to pay any such additional amounts to such Lender for any
periods which are more than one (1) year prior to the date of such notice unless
and to the extent any such additional amounts arise as a result of the
retroactive application of such change in law, treaty or regulation.

         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 2.2 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 Base 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 Base Rate Loan, unless Borrowing Agent
shall notify Agent no later than 10:00 a.m. (New York City time) 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 Base Rate Loan or Eurodollar Rate Loan which was to have
been converted to an affected type of Eurodollar Rate Loan shall be continued as
or converted into a Base Rate Loan, or, if Borrowing Agent shall notify Agent,
no later than 10:00 a.m. (New York City time) 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 Base Rate Loan, or, if Borrowing Agent shall notify Agent, no
later than 10:00 a.m. (New York City time) 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 Base 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 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 the
applicable law, regulation or condition.

                  (b) A certificate 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 Borrowers shall be conclusive
absent manifest error.


IV.      COLLATERAL; GENERAL TERMS.

         4.1. Security Interest in the Collateral. To secure the prompt payment
and performance to Agent and each Lender of the Obligations, each Borrower
hereby assigns, pledges and grants to Agent for the ratable benefit of each
Lender a continuing security interest in and to all of its Collateral, whether
now owned or existing or hereafter acquired or arising and wheresoever located.
Each Borrower shall mark its books and records as may be necessary or
appropriate to evidence, protect and perfect Agent's security interest and shall
cause its financial statements to reflect such security interest.

         4.2. Perfection of Security Interest. Each Borrower shall take all
action that may be necessary or desirable, or that Agent may reasonably request,
so as at all times to maintain the validity, perfection, enforceability and
priority of Agent's security interest in the Collateral or to enable Agent to
protect, exercise or enforce its rights hereunder and in the

 
                                      -31-

<PAGE>   38



Collateral, including, but not limited to, (i) immediately discharging all Liens
other than Permitted Encumbrances, (ii) obtaining landlords' or mortgagees' lien
waivers, (iii) delivering to Agent, endorsed or accompanied by such instruments
of assignment as Agent may specify, and stamping or marking, in such manner as
Agent may specify, any and all chattel paper, instruments, letters of credits
and advices thereof and documents evidencing or forming a part of the
Collateral, (iv) entering into warehousing, lockbox and other custodial
arrangements reasonably satisfactory to Agent, and (v) executing and delivering
financing statements, instruments of pledge, mortgages, notices and assignments,
in each case in form and substance satisfactory to Agent, relating to the
creation, validity, perfection, maintenance or continuation of Agent's security
interest under the Uniform Commercial Code or other applicable law. Agent is
hereby authorized to file financing statements signed by Agent instead of
Borrower in accordance with Section 9-402(2) of Uniform Commercial Code as
adopted in the Commonwealth of Pennsylvania. All charges, expenses and fees
Agent may incur in doing any of the foregoing, and any local taxes relating
thereto, shall be charged to Borrowers' Account as a Revolving Advance of a Base
Rate Loan and added to the Obligations, or, at Agent's option, shall be paid to
Agent for the ratable benefit of Lenders immediately upon demand.

         4.3. Disposition of Collateral. Each Borrower will use its best efforts
to safeguard and protect all Collateral for Agent's general account and make no
disposition thereof whether by sale, lease or otherwise except (a) the sale of
Inventory in the ordinary course of business and (b) the disposition or transfer
of obsolete and worn-out Equipment in the ordinary course of business during any
fiscal year having an aggregate fair market value of not more than $250,000.
Notwithstanding the foregoing, nothing in this Section 4.3 shall prohibit any
Borrower from selling any of its assets as permitted by Section 7.1 hereof.

         4.4. Preservation of Collateral. Following the occurrence of an Event
of Default in addition to the rights and remedies set forth in Section 11.1
hereof, Agent: (a) may at any time take such steps as Agent deems necessary to
protect Agent's interest in and to preserve the Collateral, including the hiring
of such security guards or the placing of other security protection measures as
Agent may deem appropriate; (b) may employ and maintain at any of any Borrower's
premises a custodian who shall have full authority to do all acts necessary to
protect Agent's interests in the Collateral; (c) may lease warehouse facilities
to which Agent may move all or part of the Collateral; (d) may use any
Borrower's owned or leased lifts, hoists, trucks and other facilities or
equipment for handling or removing the Collateral; and (e) shall have, and is
hereby granted, a right of ingress and egress to the places where the Collateral
is located, and may proceed over and through any of Borrower's owned or leased
property. Each Borrower shall cooperate fully with all of Agent's efforts to
preserve the Collateral and will take such actions to preserve the Collateral as
Agent may reasonably direct. All of Agent's expenses of preserving the
Collateral, including any expenses relating to the bonding of a custodian, shall
be charged to Borrowers' Account as a Revolving Advance of a Base Rate Loan and
added to the Obligations.

 
                                      -32-

<PAGE>   39



         4.5. Ownership of Collateral. With respect to the Collateral, at the
time the Collateral becomes subject to Agent's security interest: (a) each
Borrower shall be the sole owner of and fully authorized and able to sell,
transfer, pledge and/or grant a first priority security interest in each and
every item of the its respective Collateral to Agent; and, except for Permitted
Encumbrances the Collateral shall be free and clear of all Liens and
encumbrances whatsoever; (b) each document and agreement executed by each
Borrower or delivered to Agent or any Lender in connection with this Agreement
shall be true and correct in all respects; (c) all signatures and endorsements
of each Borrower that appear on such documents and agreements shall be genuine
and each Borrower shall have full capacity to execute same; and (d) each
Borrower's Equipment and Inventory shall be located as set forth on Schedule 4.5
and shall not be removed from such location(s) without the prior written consent
of Agent except with respect to the sale of Inventory in the ordinary course of
business and Equipment to the extent permitted in Sections 4.3 and 7.1 hereof.

         4.6. Defense of Agent's and Lenders' Interests. Until (a) payment and
performance in full of all of the Obligations and (b) termination of this
Agreement, Agent's interests in the Collateral shall continue in full force and
effect. During such period no Borrower shall, without Agent's prior written
consent, pledge, sell (except Inventory in the ordinary course of business and
Equipment to the extent permitted in Sections 4.3 and 7.1 hereof), assign,
transfer, create or suffer to exist a Lien upon or encumber or allow or suffer
to be encumbered in any way except for Permitted Encumbrances, any part of the
Collateral. Each Borrower shall defend Agent's interests in the Collateral
against any and all Persons whatsoever. At any time following demand by Agent
for payment of all Obligations, Agent shall have the right to take possession of
the indicia of the Collateral and the Collateral in whatever physical form
contained, including without limitation: labels, stationery, documents,
instruments and advertising materials. If Agent exercises this right to take
possession of the Collateral, Borrowers shall, upon demand, assemble it in the
best manner possible and make it available to Agent at a place reasonably
convenient to Agent. In addition, with respect to all Collateral, Agent and
Lenders shall be entitled to all of the rights and remedies set forth herein and
further provided by the Uniform Commercial Code or other applicable law.
Following the occurrence of a Default or Event of Default, each Borrower shall,
and Agent may, at its option, instruct all suppliers, carriers, forwarders,
warehouses or others receiving or holding cash, checks, Inventory, documents or
instruments in which Agent holds a security interest to deliver same to Agent
and/or subject to Agent's order and if they shall come into any Borrower's
possession, they, and each of them, shall be held by such Borrower in trust as
Agent's trustee, and such Borrower will immediately deliver them to Agent in
their original form together with any necessary endorsement.

         4.7. Books and Records. Each Borrower shall (a) keep proper books of
record and account in which full, true and correct entries will be made of all
dealings or transactions of or in relation to its business and affairs; (b) set
up on its books accruals with

 
                                      -33-

<PAGE>   40



respect to all taxes, assessments, charges, levies and claims; and (c) on a
reasonably current basis set up on its books, from its earnings, allowances
against doubtful Receivables, advances and investments and all other proper
accruals (including without limitation by reason of enumeration, accruals for
premiums, if any, due on required payments and accruals for depreciation,
obsolescence, or amortization of properties), which should be set aside from
such earnings in connection with its business. All determinations pursuant to
this subsection shall be made in accordance with, or as required by, GAAP
consistently applied in the opinion of such independent public accountant as
shall then be regularly engaged by Borrowers.

         4.8. Financial Disclosure. Each Borrower hereby irrevocably authorizes
and directs all accountants and auditors employed by such Borrower at any time
during the Term to exhibit and deliver to Agent and each Lender copies of any of
any Borrower's financial statements, trial balances or other accounting records
of any sort in the accountant's or auditor's possession, and to disclose to
Agent and each Lender any information such accountants may have concerning such
Borrower's financial status and business operations.

         4.9. Compliance with Laws. Each Borrower shall comply with all acts,
rules, regulations and orders of any legislative, administrative or judicial
body or official applicable to its respective Collateral or any part thereof or
to the operation of such Borrower's business the 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 any related Lien is inchoate or 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 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 so that such
insurance shall remain in full force and effect.

         4.10. Collateral Inspection and Monitoring. At all reasonable times
and, prior to the occurrence of a Default or Event of Default, upon prior notice
to Borrowers, Agent and each Lender shall have full access to and the right to
monitor, examine, audit, check and inspect the Collateral and each Borrower's
books, records, audits, correspondence and all other papers relating to the
Collateral and the operation of each Borrower's business and to make abstracts
and copies of any thereof. 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, and, prior to the occurrence of a
Default or Event of Default, upon prior notice to Borrowers for the purpose of
inspecting and monitoring the Collateral and any and all records pertaining
thereto and the operation of such Borrower's business.

         4.11. Insurance. Each Borrower shall bear the full risk of any loss of
any nature

 
                                      -34-

<PAGE>   41



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 insurable properties and properties in which each Borrower 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, without limitation, 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
hereby are 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. 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, provided that prior to the occurrence of a
Default or Event of Default any such recoveries in respect of Equipment of up to
an aggregate of $500,000 shall be paid by Agent to Borrowers and applied by
Borrowers to the replacement of any Equipment purchased with the proceeds of an
Equipment Advance. 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
Base Rate Loan and such

 
                                      -35-

<PAGE>   42



expenses so paid shall be part of the Obligations.

         4.13. Payment of Taxes. Each Borrower will pay, when due, all taxes,
assessments and other Charges lawfully levied or assessed upon such Borrower or
any of the Collateral including, without limitation, 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 taxes, assessments, or other 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 taxes, assessments or
other Charges and each Borrower hereby indemnifies and holds Agent and each
Lender harmless in respect thereof. Agent will not pay any taxes, assessments or
Charges to the extent that any Borrower has contested or disputed those taxes,
assessments or Charges in good faith, by expeditious protest, administrative or
judicial appeal or similar proceeding provided that any related tax lien is
stayed and sufficient reserves are established to the reasonable satisfaction of
Agent to protect Agent's security interest in or Lien on the Collateral. 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 a tenant, and shall otherwise comply, in all material respects, with all
other terms of such leases and keep them in full force and effect and, at
Agent's request will provide evidence of having done so.

         4.15. Receivables.

                  (a) Nature of Receivables. Each of the Receivables shall be a
bona fide and valid account representing a bona fide indebtedness incurred by
the Customer therein named, for a fixed sum as set forth in the invoice relating
thereto (provided immaterial or unintentional invoice errors shall not be deemed
to be a breach hereof) with respect to an absolute sale or lease and delivery of
goods upon stated terms of a Borrower, or work, labor or services theretofore
rendered by a Borrower as of the date each Receivable is created. Same shall be
due and owing in accordance with the applicable Borrower's standard terms of
sale without dispute, setoff or counterclaim except as may be stated on the
accounts receivable schedules delivered by Borrowers to Agent.


 
                                      -36-

<PAGE>   43



                  (b) Solvency of Customers. Each Customer, to the best of each
Borrower's knowledge, as of the date each Receivable is created, is and will be
solvent and able to pay all Receivables on which the Customer is obligated in
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.

                  (c) Locations of Borrower. Each Borrower's chief executive
office is located at the addresses set forth on Schedule 4.15(c) hereto. Until
written notice is given to Agent by Borrowing Agent of any other office at which
any Borrower keeps its records pertaining to Receivables, all such records shall
be kept at such executive office.

                  (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 an Event of Default or when Agent in its sole but
reasonable discretion deems it to be in Lenders' best interest to do so), each
Borrower will, at such Borrower's sole cost and expense, but on Agent's behalf
and for Agent's 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 or use the same except to pay Obligations. Each Borrower
shall, upon request, deliver to Agent, or deposit in the Blocked Account, in
original form and on the date of receipt thereof, all checks, drafts, notes,
money orders, acceptances, cash and other evidences of Indebtedness of any
account debtor.

                  (e) Notification of Assignment of Receivables. At any time
after the occurrence of an Event of Default, Agent shall have the right to send
notice of the assignment of, and Agent's security interest in, the Receivables
to any and all Customers or any third party holding or otherwise concerned with
any of the Collateral. Thereafter, Agent shall have the sole right to collect
the Receivables, take possession of the Collateral, or both. Agent's actual
collection expenses, including, but not limited to, stationery and postage,
telephone and telegraph, secretarial and clerical expenses and the salaries of
any collection personnel used for collection, may be charged to Borrowers'
Account and added to the Obligations.

                  (f) Power of Agent to Act on Borrowers' Behalf. Agent shall
have the 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 money relating to the Receivables, and each Borrower hereby waives notice of
presentment, protest and non-payment of any instrument so endorsed. Each
Borrower hereby constitutes Agent or Agent's designee as such Borrower's
attorney with power (i) to endorse such Borrower's name upon any notes,
acceptances, checks, drafts, money orders or other evidences of payment or
Collateral; (ii) to sign such Borrower's name on any invoice or bill of lading
relating to any of the Receivables, drafts against Customers, assignments and

Borrower's name on all financing statements or any other documents or

(xii) to do all other acts and things reasonably necessary to carry out this
Agreement. All acts of said attorney or designee are hereby ratified and
approved, and said attorney or designee shall not be liable for any acts of

being coupled with an interest is irrevocable while any of the Obligations
remain unpaid. Agent shall have the right at any time after the occurrence of an
Event of Default, to change the address for delivery of mail addressed to any
Borrower to such address as Agent may designate and to receive, open and dispose

                  (g) No Liability. Neither Agent nor any Lender shall, under
any circumstances or in any event whatsoever, have any liability for any error
or omission or delay of any kind occurring in the settlement, collection or

applicable thereto and/or release any obligor thereof. Agent is authorized and
empowered to accept after the occurrence of an Event of Default or Default the
return of the goods represented by any of the Receivables, without notice to or
consent by any Borrower, all without discharging or in any way affecting any
Borrower's liability hereunder.

proceeds of Collateral shall, at the direction of Agent, be deposited by
Borrowers into a lockbox account, dominion account or such other "blocked

with such bank as may be selected by Borrowers and be acceptable to Agent.
Borrowers shall issue to any such bank, an irrevocable letter of instruction
directing said bank to transfer such funds so deposited to Agent, either to any
account maintained by Agent at said bank or by wire transfer to appropriate
account(s) of Agent. All funds deposited in such "blocked account" shall
immediately become the

 
                                      -38-

<PAGE>   45



property of Agent and Borrowers shall obtain the agreement by such bank to waive
any offset rights against the funds so deposited. Neither Agent nor any Lender
assumes any responsibility for such "blocked account" arrangement, including
without limitation, any claim of accord and satisfaction or release with respect
to deposits accepted by any bank thereunder. Alternatively, Agent may establish
depository accounts ("Depository Accounts") in the name of Agent at a bank or
banks for the deposit of such funds and Borrowers shall deposit all proceeds of
Collateral or cause same to be deposited, in kind, in such Depository Accounts
of Agent in lieu of depositing same to the Blocked Accounts.

or credits thereon except for those compromises, adjustments, returns,
discounts, credits and allowances as have been heretofore customary in the
business of such Borrower.

         4.16. Inventory. To the extent Inventory held for sale or lease has
been produced by any Borrower, it has been and will be produced by such Borrower
in accordance with the Federal Fair Labor Standards Act of 1938, as amended, and
all rules, regulations and orders thereunder.

         4.17. Maintenance of Equipment. The Equipment shall be maintained in
good operating condition and repair (reasonable wear and tear excepted) and all
necessary replacements of and repairs thereto shall be made so that the value
and operating efficiency of the Equipment shall be maintained and preserved. No
Borrower shall use or operate the Equipment in violation of any law, statute,
ordinance, code, rule or regulation. Each Borrower shall have the right to sell
Equipment to the extent set forth in Sections 4.3 and 7.1 hereof.

         4.18. Exculpation of Liability. Nothing herein contained shall be
construed to constitute Agent or any Lender as any Borrower's agent for any
purpose whatsoever, nor shall Agent or any Lender be responsible or liable for
any shortage, discrepancy, damage, loss or destruction of any part of the
Collateral wherever the same may be located and regardless of the cause thereof.
Neither Agent nor any Lender, whether by anything herein or in any assignment or
otherwise, assume any of any Borrower's obligations under any contract or
agreement assigned to Agent or such Lender, and neither Agent nor any Lender
shall be responsible in any way for the performance by any Borrower of any of
the terms and conditions thereof.

         4.19. Environmental Matters. (a) Borrowers shall use their best efforts

                  (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
maintain valid permits under RCRA and any other applicable Environmental Laws.
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 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.

<PAGE>   47



                  (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) deem 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 Base 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 upon the written request of Agent from time to
time if Agent reasonably believes that any Borrower may have violated any
Environmental Law, 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, without limitation, 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

 
                                      -41-

<PAGE>   48



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.

                  (i) For purposes of Section 4.19 and 5.7, all references to
Real Property shall be deemed to include all of Borrowers' right, title and
interest in and to its owned and leased premises.

         4.20. Financing Statements. Except as respects the financing statements
filed by Agent and the financing statements described on Schedule 1.2, no
financing statement covering any of the Collateral or any proceeds thereof is on
file in any public office.

reasonably likely to incur, a liability to a Plan or the PBGC (or both) which,
in the reasonable judgment of Agent, would have a Material Adverse Effect on any
Borrower.


XI.      LENDERS' RIGHTS AND REMEDIES AFTER DEFAULT.

         11.1. Rights and Remedies. Upon the occurrence of (i) an Event of
Default pursuant to Section 10.7 all Obligations shall be immediately due and
payable and this Agreement and the obligation of Lenders to make Advances shall
be deemed terminated; and, (ii) any of the other Events of Default and at any
time thereafter (such default not having previously been cured), at the option
of Required Lenders all Obligations shall be immediately due and payable and
Lenders shall have the right to terminate this Agreement

 
                                      -63-

<PAGE>   70



and to terminate the obligation of Lenders to make Advances and (iii) a filing
of a petition against any Borrower in any involuntary case under any state or
federal bankruptcy laws, the obligation of Lenders to make Advances hereunder
shall be terminated other than as may be required by an appropriate order of the
bankruptcy court having jurisdiction over any Borrower. Upon the occurrence of
any Event of Default, Agent shall have the right to exercise any and all other
rights and remedies provided for herein, under the Uniform Commercial Code and
at law or equity generally, including, without limitation, the right to
foreclose the security interests granted herein and to realize upon any
Collateral by any available judicial procedure and/or to take possession of and
sell any or all of the Collateral with or without judicial process. Agent may
enter any of Borrower's premises or other premises without legal process and
without incurring liability to any Borrower therefor, and Agent may thereupon,
or at any time thereafter, in its 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 more sales, at such price or prices, and
upon such terms, either for cash, credit or future delivery, as Agent may elect.
Except as to that part of the Collateral which is perishable or threatens to
decline speedily in value or is 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 sold absolutely free from any claim or right of whatsoever kind,
including any equity of redemption and such right and equity are hereby
expressly waived and released by each Borrower. In connection with the exercise
of the foregoing remedies, Agent is granted permission to use all of each
Borrower's trademarks, trade styles, trade names, patents, patent applications,
licenses, franchises and other proprietary rights which are used in connection
with (a) Inventory for the purpose of disposing of such Inventory and (b)
Equipment for the purpose of completing the manufacture of unfinished goods. The
proceeds realized from the sale of any Collateral shall be applied as follows:
first, to the reasonable costs, expenses and attorneys' fees and 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 Agreement; and,
third, to the principal of the Obligations. If any deficiency shall arise,
Borrowers shall remain liable to Agent and Lenders therefor.

         11.2. Agent's Discretion. Agent shall have the right in its sole
discretion to determine which rights, Liens, security interests or remedies
Agent may at any time pursue, relinquish, subordinate, or modify or to take any
other action with respect thereto and such determination will not in any way
modify or affect any of Agent's or Lenders' rights hereunder.

 
                                      -64-

<PAGE>   71



         11.3. Setoff. In addition to any other rights which Agent or any Lender
may have under applicable law, upon the occurrence of an Event of Default
hereunder, Agent and such Lender shall have a right to apply any Borrower's
property held by Agent and such Lender to reduce the Obligations.

         11.4. Rights and Remedies not Exclusive. The enumeration of the
foregoing rights and remedies is not intended to be exhaustive and the exercise
of any right or remedy shall not preclude the exercise of any other right or
remedies provided for herein or otherwise provided by law, all of which shall be
cumulative and not alternative.


XII.     WAIVERS AND JUDICIAL PROCEEDINGS.

         12.1. Waiver of Notice. Each Borrower hereby waives notice of
non-payment of any of the Receivables, demand, presentment, protest and notice
thereof with respect to any and all instruments, notice of acceptance hereof,
notice of loans or advances made, credit extended, Collateral received or
delivered, or any other action taken in reliance hereon, and all other demands
and notices of any description, except such as are expressly provided for
herein.

         12.2. Delay. No delay or omission on Agent's or any Lender's part in
exercising any right, remedy or option shall operate as a waiver of such or any
other right, remedy or option or of any default.

         12.3. Jury Waiver. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES
ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A)
ARISING UNDER THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT
EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH
OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM
WITH RESPECT TO THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT
EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO
OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER
SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND EACH PARTY HEREBY CONSENTS THAT
ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT
TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL
COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE
CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

XIII.    EFFECTIVE DATE AND TERMINATION.

         13.1. Term. This Agreement, which shall inure to the benefit of and
shall be binding upon the 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 __, 2002 (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"), Borrowers shall pay to Agent for the benefit of
Lenders an early termination fee in an amount equal to $250,000 if the Early
Termination Date occurs on or after the Closing Date to and including the date
immediately preceding the second 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 Uniform Commercial Code 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.


XIV.     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 this Agreement and the Other 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

 
                                      -66-

<PAGE>   73



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 and collections
(without giving effect to any collection days) received pursuant to this
Agreement, for 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 without limitation,
collection of the Note) 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, this Agreement or any of the
Other Documents or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement, or any of the Other 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, this Agreement or any of the Other 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. 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,

 
                                      -67-

<PAGE>   74



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 this Agreement or any Other Document, 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 Note, the Other Documents or the financial
condition of any Borrower, or the existence of any Event of Default or any
Default.

         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 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
Article XIV 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

 
                                      -68-

<PAGE>   75



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, 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 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.

         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.

XV.      BORROWING AGENCY.

         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. Neither Agent nor
any Lender shall incur liability to Borrowers as a result thereof. 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 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.

         15.2. Waiver of Subrogation. Each Borrower expressly waives any and all
rights of subrogation, reimbursement, indemnity, exoneration, contribution of
any other claim which 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, without limitation, 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.

XVI.     MISCELLANEOUS.

         16.1. Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania applied to
contracts to be performed wholly within the Commonwealth of Pennsylvania. 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 Commonwealth of Pennsylvania, 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 Commonwealth of
Pennsylvania. Nothing herein shall affect the right to serve process in any
manner permitted by 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 Philadelphia, Commonwealth of Pennsylvania.

         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 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

 
                                      -71-

<PAGE>   78



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 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 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 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) increase the Maximum Revolving Advance Amount or
permit any Advance to be made if after giving effect thereto the total of
Advances outstanding hereunder would exceed the Formula Amount for more than
sixty (60) consecutive Business Days or exceed one hundred and ten percent
(110%) of the Formula Amount.

                           (vii) increase the Advance Rates above the Advance
Rates 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) days of delivery of such request, such Lender shall be deemed to
have consented to matter that

 
                                      -72-

<PAGE>   79



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
"Transferee"). Each Transferee may exercise all rights of payment (including
without limitation 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
Transferee were the direct holder thereof provided that Borrowers shall not be
required to pay to any Transferee 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 Transferee 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 Transferee. Each Borrower hereby
grants to any Transferee a continuing security interest in any deposits, moneys
or other property actually or constructively held by such Transferee as security
for the Transferee'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 this Agreement and the Other Documents to one or more
additional banks or financial institutions and one or more additional banks or
financial institutions may commit to make Advances hereunder (each a "Purchasing
Lender"), in minimum amounts of not less than

 
                                      -73-

<PAGE>   80



$5,000,000, pursuant to a Commitment Transfer Supplement, executed by a
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. 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 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 $2,500 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
Transferee or Purchasing Lender and any prospective Transferee 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.

                  (f) Without otherwise limiting its rights under this Section
16.3, PNC acknowledges that it will retain at least 51% of the Advances and
Commitment Percentages.

         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

 
                                      -74-

<PAGE>   81



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, without limitation, 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 agency or instrumentality or any other Person with
respect to any aspect of, or any transaction contemplated by, or referred to in,
or any matter related to, this Agreement or the Other 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 gross negligence or misconduct 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 shall be given by (a) hand delivery, (b) overnight courier, (c)
registered or certified mail, return receipt requested, (d) telex or telegram,
subsequently confirmed by registered or certified mail, or (e) telecopy to the
number set out below (or such other number as may hereafter be specified in a
notice designated as a notice of change of address) with electronic confirmation
of its receipt. Any notice or other communication required or permitted pursuant
to this Agreement shall be deemed given (a) when personally delivered to any
officer of the party to whom it is addressed, (b) on the earlier of actual
receipt thereof or three (3) days following posting thereof by certified or
registered mail, postage prepaid, or (c) upon actual receipt thereof when sent
by a recognized overnight delivery service or (d) upon actual receipt thereof
when sent by telecopier to the number set forth below with electronic
confirmation of its receipt, in each case addressed to each party at its address
set forth below or at such other address as has been furnished in writing by a

3.7, 3.8, 3.9, 4.19(h), 14.7 and 16.5 shall survive termination of this

         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,
prohibited or invalid, but the remainder hereof shall not be invalidated thereby
and shall be given effect so far as possible.

         16.10. Injunctive Relief. Each Borrower recognizes that, in the event
any Borrower fails to perform, observe or discharge any of its obligations or
liabilities under this Agreement, any remedy at law may prove to be inadequate
relief to Lenders; therefore, Agent, if Agent so requests, shall be entitled to
temporary and permanent injunctive relief in any such case without the necessity
of proving that actual damages are not an adequate remedy.

         16.11. Consequential Damages. Neither Agent nor any Lender, nor any

consequential damages arising from any breach of contract, tort or other wrong
relating to the establishment, administration or collection of the Obligations.

         16.12. Captions. The captions at various places in this Agreement are
