                                      (9)

The date and amount of each Revolving Credit Loan, the basis for calculating
interest, the Interest Period applicable thereto and each payment of principal
with respect thereto shall be endorsed by the Banks on the schedule annexed to

amount of Revolving Credit Loans set forth on such schedule shall be presumed to

loan is made and upon payment in full thereof.  Interest on each LIBOR Rate Loan

or less, at the end of each applicable Interest Period and (ii) in the case of
Revolving Credit Loans with Interest Periods of more than three months, at the
end of each calendar quarter and at the end of the Interest Period.  Whenever

benefit of the Banks at a rate per annum (computed daily) equal to 2% percent

          2.6   Conversion and Renewals.  The Borrower may elect from time to
                -----------------------                                      
time to convert all or a part of one type of Revolving Credit Loan into another
type of Revolving Credit Loan or to renew all or part of a Revolving Credit Loan

conversion date; (2) the amount of the Revolving Credit Loan to be converted or
renewed; (3) in the case of conversions, the type of Revolving Credit Loan to be

that (a) the minimum principal amount of each Revolving Credit Loan outstanding
after a renewal or conversion to a LIBOR Rate Loan shall be $250,000 or to a
Prime Rate Loan shall be $100,000; and (b) LIBOR Rate Loans can be converted
only on the last day of the Interest Period of such Loan.  All notices given
under this Section 2.6 shall be irrevocable and shall be given not later than

advise (but in any event, by 2:00 p.m. Philadelphia time, two (2) Business Days
prior to a LIBOR Rate Loan or by 11:00 a.m. on the same Business Day in the case
of a Prime Rate Loan) the Banks of any notice given pursuant to this Section 2.6
and of each Bank's portion of the requested conversion or renewal.

           2.7  Suspension of LIBOR Rate Loans.
                ------------------------------ 

                (a) Disaster. Notwithstanding anything contained in this 
                    --------  
Agreement to the contrary, if the Agent determines that:

                (i) it is unable for any reason to quote or determine rates 
                    based upon a LIBOR Rate, or

               (ii) the LIBOR Rate does not accurately reflect the cost to a 
                    Bank of making or maintaining a LIBOR Rate Loan

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition shall remain in effect the right of the Borrower to select a
LIBOR Rate Loan or to convert a Prime Rate Loan into a LIBOR Rate Loan shall be
suspended.  The Borrower, in such event, shall, on the last day of a then
current Interest Period either prepay such loan together with accrued interest
thereon or convert such loan into a Prime Rate Loan.

          (b) Illegality.  Notwithstanding any other provisions herein, if any
              ----------                                                      
Requirements of Law, regulation, order or decree or any change therein or in the
interpretation or application thereof shall make it unlawful for a Bank to make
or maintain LIBOR Rate Loans as contemplated by this Agreement, the Commitment
hereunder to make LIBOR Rate Loans shall forthwith be canceled with respect to
such Bank upon notice to the Agent and the Borrower and Revolving Credit Loans
then outstanding as LIBOR Rate Loans, if any, shall, at the option of the
Borrower, be prepaid in full together with all interest accrued and unpaid to
the date of any such prepayment together with any amounts required by Section
2.10 hereof, or converted into a Prime Rate Loan.

          2.8  Applicable Margin; Periods, Etc.  The applicable Margin
               -------------------------------                                  
shall be reset four times each fiscal year for the relevant periods set forth
below, based upon the Leverage 

                                      (13)
<PAGE>
 
Ratio, as reflected at the close of the statement period in the Borrower's
consolidated financial statements indicated in the table below, as follows:
 
          Financial                        Margin Period of
          Statements                       Each Fiscal Year
          ----------                       ----------------
 
          1st Quarter                August 1 - October 31
          2nd Quarter                November 1 - January 31
          3rd Quarter                February 1 - June 15
          Annual(Fiscal Year End)          June 16 - July 31

          2.9  Commitment Fee.  As additional compensation for the Revolving
               --------------                                               
Credit Commitment, the Borrower agrees to pay the Agent for the pro rata benefit
of the Banks a commitment fee for the Commitment Period based on the average
daily unused portion of the Total Revolving Credit Commitments and the
applicable Leverage Ratio in the amount of:

          .075% per annum if the Leverage Ratio is                  less 
          than 2.50:1,
          .15% per annum if the Leverage Ratio is equal to or 
          greater than 2.50:1.

Any fee payable under this Section 2.9 which is not paid when due shall bear
interest at a rate per annum equal to 2% above the Prime Rate until paid,
payable on demand.  Such fee shall be computed on the basis of a 360 day year
for the actual days elapsed and shall be payable monthly on the first day of
each month during the Commitment Period and on the Termination Date.  The
"unused portion of the Total Revolving Credit Commitments" means, at any time,
the Total Revolving Credit Commitments less the sum of (a) the unpaid principal
balance of all Revolving Credit Loans, (b) Letter of Credit Exposure and (c)
Acceptance Draft Exposure.  Upon termination or reduction of the Revolving
Credit Commitments, the Borrower will pay to the Agent, for the pro rata account
of the Banks, accrued unused fees on the portion of the Revolving Credit
Commitment terminated or reduced to the date of termination or reduction.

interpretation or application thereof by any Governmental Authority charged with
the interpretation or administration thereof or compliance with any request or
directive of any Governmental Authority (whether or not having the force of law)
now existing or hereafter adopted:

          (i) subjects the Agent or a Bank to any tax or changes the basis of
              taxation with respect to this Agreement, the Revolving Credit
              Notes, the Revolving Credit Loans or payments by the Borrower of
              principal, interest, commitment fee or other amounts due from the
              Borrower hereunder or under the Revolving Credit Notes (except for
              taxes on the overall net income of the Agent or a Bank imposed by
              the jurisdiction in which the Agent or such Bank's principal
              office is located),

         (ii) imposes, modifies or deems applicable any reserve, special deposit
              or similar requirement against credits or commitments to extend
              credit extended by, assets (funded or contingent) of, deposits
              with or for the account of, or other acquisition of funds by, the
              Agent or a Bank (or participation therein) (other than
              requirements expressly included herein in the determination of the
              LIBOR Rate hereunder),

        (iii) imposes, modifies or deems applicable any capital adequacy or
              similar requirement (A) against assets (funded or contingent) of,
              or credits or commitments to extend credit extended by, the Agent
              or a Bank (or participations therein) or (B) otherwise applicable
              to the obligations of the Agent or a Bank under this Agreement, or

         (iv) imposes upon the Agent or a Bank any other condition or expense
              with respect to this Agreement, the Revolving Credit Notes or its

                                      (15)
<PAGE>
 
              making, maintenance or funding any part of the Revolving Credit
              Loans (or participations therein),

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon the
Agent or a Bank with respect to this Agreement, the Revolving Credit Notes or
the making, maintenance or funding of any part of the Revolving Credit Loans
(or, in the case of any capital adequacy or similar requirement, to have the
effect of reducing the rate of return on the Agent's or a Bank's capital, taking
into consideration the Agent's and such Bank's policies with respect to capital
adequacy) by an amount which the Agent or a Bank deems to be material, the Agent
or Bank shall from time to time notify the Borrower of the amount determined in
good faith (using any averaging and attribution methods) by the Agent or Bank
(which determination shall be conclusive) to be necessary to compensate the
Agent or Bank for such increase, reduction or imposition.  Such amount shall be
due and payable by the Borrower to the Agent or Bank ten (10) ten Business Days
after such notice is given.  A certificate by the Agent or Bank as to the amount
due and payable under this Section 2.10(a) from time to time and the method of
calculating such amount shall be conclusive absent manifest error.

          All references to "Bank" shall be deemed to include any participant in
such Bank's Revolving Credit Commitment.

          (b) Indemnity.  In addition to the compensation required by subsection
              ---------                                                         
(a) of this Section 2.10, the Borrower shall indemnify the Agent and a Bank
against any loss or expense (including loss of margin) which the Agent or Bank
has sustained or incurred as a consequence of any

          (i) payment, prepayment or conversion of any part of any LIBOR Rate
              Loan on a day other than the last day of the applicable Interest
              Period (whether or not such payment, prepayment or conversion is
              mandatory or automatic and whether or not such payment or
              prepayment is then due).

                                      (16)

         (ii) attempt by the Borrower to revoke (expressly, by later
              inconsistent notices or otherwise) in whole or part any notice
              stated herein to be irrevocable (the Agent having in its sole
              discretion the options (A) to give effect to such attempted
              revocation and obtain indemnity under this Section 2.10(b) or (B)
              to treat such attempted revocation as having no force or effect,
              as if never made), or

        (iii) default by the Borrower in the performance or observance of any
              covenant or condition contained in this Agreement or the Revolving
              Credit Notes, including without limitation any failure of the
              Borrower to pay when due (by acceleration or otherwise) any
              principal, interest, commitment fee or any other amount due
              hereunder or under a Revolving Credit Note.

If the Agent or Bank sustains or incurs any such loss or expense it shall from
time to time notify the Borrower of the amount determined in good faith by the
Agent or Bank (which determination shall be conclusive) to be necessary to
indemnify the Agent or Bank for such loss or expense.  Such amount shall be due
and payable by the Borrower to the Agent or Bank ten (10) Business Days after
such notice is given.

          All references to "Bank" shall be deemed to include any participant in
such Bank's Revolving Credit Commitment.

          The indemnities set forth herein shall survive payment in full of all
LIBOR Rate Loans and all other Revolving Credit Loans made pursuant to this
Agreement.

          2.11  Termination or Reduction of Commitment.  Subject to the
                --------------------------------------                 
indemnity agreement with respect to LIBOR Rate Loans set forth in Section
2.10(b) hereof, the Borrower shall have the right, upon not less than three (3)
Business Days' irrevocable notice to the Agent, to terminate the Total Revolving
Credit Commitment or, from time to time, to reduce the amount of the Total
Revolving Credit Commitment, provided that (a) any such reduction (i) shall be
in the minimum amount of $1,000,000 or a multiple thereof, (ii) shall

                                      (17)
<PAGE>
 
reduce permanently the amount of the Total Revolving Credit Commitment then in
effect, and (iii) shall be accompanied by prepayment of the Revolving Credit
Loans outstanding, together with accrued interest on the amount so prepaid to
the dates of each such prepayment, to the extent, if any, that the Revolving
Credit Loans then outstanding exceed the amount of the Total Revolving Credit
Commitment as then reduced, and (b) any such termination of the Total Revolving
Credit Commitment shall be accompanied by prepayment in full of the Revolving
Credit Loans outstanding, together with accrued interest thereon to the date of
prepayment, and the payment of any unpaid commitment fee then accrued hereunder.

          2.12  Prepayment.  Subject to the indemnity agreement with respect to
                ----------                                                     
LIBOR Rate Loans set forth in Section 2.10(b) hereof, the Borrower may prepay
any Revolving Credit Loan in whole or in part without premium or penalty
together with interest accrued on the amount prepaid to the date of prepayment.
Prepayments of Revolving Credit Loans may be reborrowed on a revolving basis as
aforesaid.

          2.13  Payments.
                -------- 

          (a) All payments (including prepayments) to be made by the Borrower on
account of principal, interest and fees shall be made without setoff or
counterclaim and shall be made to the Bank on the date of payment at the office
of the Agent set forth in Section 10.1 hereof or at such other place as the
Agent may from time to time designate in writing on or before 11:00 a.m.
(Philadelphia time), in each case in lawful money of the United States of
America and in immediately available funds.  If any payment hereunder (other
than payments on LIBOR Rate Loans) becomes due and payable on a day other than a
Business Day, such payment shall be extended to the next succeeding Business Day
and, with respect to payments of principal, interest thereon shall be payable at
the then applicable rate during such extension.  If any payment on a LIBOR Rate
Loan becomes due and payable on a day other than a Business Day, the maturity
thereof shall be extended to the next succeeding Business Day unless the result
of such extension would be to extend such payment into another calendar month in
which event such payment shall be made on the immediately preceding Business
Day.

                                      (18)

          (b) The Borrower hereby authorizes the Agent to charge any of its
accounts maintained at the Agent on the date any payment is due hereunder or
under the Revolving Credit Note.

           2.14  Pro Rata Treatment.
                 ------------------ 

          (a) Except for any payment, reimbursement or other indemnity to any
Bank or other indemnified person under Section 2.7(b), 2.10, 2.19 or 10.4
hereof, each borrowing, each payment or prepayment of principal of the Revolving
Credit Notes, each payment of interest on the Revolving Credit Notes, each
payment of any fee or other amount payable hereunder and each reduction of the
Total Revolving Credit Commitment shall be made pro rata between the Banks in
the proportions that their Revolving Credit Commitments bear to the Total
Revolving Credit Commitment.

          (b) Unless the Agent shall have been notified in writing by any Bank
prior to the time the Bank is required to fund any proposed borrowing that such
Bank will not make the amount that would constitute its pro rata share of the
borrowing on such date available to the Agent, the Agent may (assuming that the
Agent has furnished such Bank with notice of the proposed borrowing as required
under Section 2.5 hereof) assume that such Bank has made such amount available
to the Agent on such date, and the Agent may, in reliance upon such assumption,
make available to the Borrower a corresponding amount.  If such amount is made
available by such Bank to the Agent on a date after such borrowing date, such
Bank shall pay to the Agent on demand an amount equal to the product of (i) the
daily average Federal funds rate during such period as quoted by the Agent,
times (ii) the amount of such Bank's pro rata share of such borrowing, times
(iii) a fraction the numerator of which is the number of days that elapse from
and including such borrowing date to the date on which such Bank's pro rata
share of such borrowing shall have become immediately available to the Agent and
the denominator of which is 360.  A certificate of the Agent submitted to any
Bank with respect to any amounts owing under this subsection shall be conclusive
in the absence of manifest error. If such Bank's pro rata share of such
borrowing is not in fact made available to the Agent by such Bank within three
(3) Business Days of such borrowing date, the Agent shall be entitled to recover
such amount with interest thereon at the rate per annum applicable to the
relevant Revolving Credit Loans hereunder, on demand, from the Borrower.

          (c) Notwithstanding the foregoing provisions of this Section 2.14, in
the event that a Bank fails to make any amount that would constitute its pro
rata share of a borrowing available 

                                      (20)
<PAGE>
 
to the Agent, the Agent shall so notify the other Bank(s) whereupon such Bank(s)
shall be required to make such amount available to the Agent on a pro rata basis
between (or among) the Banks in the proportions that their Revolving Credit
Commitments bear to the Total Revolving Credit Commitment, in an aggregate
amount not to exceed the amount of such Bank's Revolving Credit Commitment as
set forth on Schedule A attached hereto.

          2.15  Sharing of Setoffs.  Each Bank agrees that if it shall, through
                ------------------                                             
the exercise of a right of banker's lien, setoff or counterclaim against the
Borrower or a Guarantor, including, but not limited to, a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Bank under any
applicable bankruptcy, insolvency or other similar law or otherwise, obtain
payment (voluntary or involuntary) in respect of a Revolving Credit Note held by
it as a result of which the unpaid principal portion of the Revolving Credit
Notes held by it shall be proportionately less than the unpaid principal portion
of the Revolving Credit Notes held by any other Bank, it shall be deemed to have
simultaneously purchased from such other Bank a participation in the Revolving
Credit Notes held by such other Bank with the purchase price payable in cash
upon demand by such other Bank, so that the aggregate unpaid principal amount of
the Revolving Credit Notes and participations in Revolving Credit Notes held by
it shall be in the same proportion to the aggregate unpaid principal amount of
all Revolving Credit Notes then outstanding as the principal amount of the
Revolving Credit Notes held by it prior to such exercise of banker's lien,
setoff or counterclaim was to the principal amount of all Revolving Credit Notes
outstanding prior to such exercise of banker's lien, setoff or counterclaim;
provided, however, that if any such purchase or purchases or adjustments shall
be made pursuant to this Section 2.15 and such other Bank shall thereafter
receive or recover from or respecting the Borrower or any Guarantor any amount
in respect of a Revolving Credit Note proportionally greater than that received
by the first Bank, such purchase or purchases or adjustments shall be
repurchased and rescinded to the extent of such receipt or recovery and the
purchase price or prices paid or adjustments made shall be repaid or restored,
as applicable, without interest; provided, that, if such disproportionate amount
received or recovered by such other Bank exceeds the amount necessary to restore
the Banks respective pro rata shares, then this section shall apply to such

                                      (21)
<PAGE>
 
excess.  The Borrower expressly consents to the foregoing arrangements and
agrees that any Bank holding a participation in a Revolving Credit Note deemed
to have been so purchased may exercise any and all rights of banker's lien,
setoff or counterclaim with respect to any and all moneys owing by the Borrower
to such Bank as fully as if such Bank held a Revolving Credit Note in the amount
of such participation.

          2.16  Use of Proceeds.  The Borrower will utilize the proceeds of the
                ---------------                                                
initial Revolving Credit Loans to repay any amounts owing to Fleet Bank, N.A.
("Fleet") under the existing revolving credit facility with Fleet.  Any
remaining proceeds of the initial borrowing and of any subsequent Revolving
Credit Loans may be used by the Borrower for working capital purposes, capital
expenditures and to fund the purchase price of Permitted Acquisitions provided
no portion of the proceeds of any Revolving Credit Loan shall be used by any
Borrower in any manner which might cause the borrowing or the application of
such proceeds to violate Regulation G, Regulation U, Regulation T or Regulation
X of the Board of Governors of the Federal Reserve System.

          2.17  Issuance of Letters of Credit.  Upon the request of the
                -----------------------------                          
Borrower, and subject to the conditions set forth herein and such other
conditions to the opening of Letters of Credit as the Agent requires of its
customers generally, the Agent shall from time to time issue documentary or
standby letters of credit (each, a "Letter of Credit") for the account of the
Borrower.  The issuance of each Letter of Credit shall be made on at least one
(1) Business Day's prior written notice from the Borrower to the Agent which
written notice shall be an application for a Letter of Credit on the Agent's
customary form.  The expiration date of any Letter of Credit shall not be later
than one (1) year from the date of issuance thereof nor, in any event, later
than the Termination Date.  The Letters of Credit shall be issued in respect of
any transactions occurring in the Borrower's ordinary course of business.

          2.18  Actions of Agent.  Any Letter of Credit may, in the discretion
                ----------------                                              
of the Agent or its correspondents, be interpreted by them (to the extent not
inconsistent with such Letter of Credit) in accordance with the Uniform Customs
and Practice for Documentary Credits of the International Chamber of Commerce,
as adopted or amended from time to time, or any other rules, regulations and

                                      (22)
<PAGE>
 
customs prevailing at the place where any Letter of Credit is available or the
drafts are drawn or negotiated.  The Agent and its correspondents may in good
faith accept and act upon the name, signature, or act of any party purporting to
be the executor, administrator, receiver, trustee in bankruptcy, or other legal
representative of any party designated in any Letter of Credit in the place of
the name, signature, or act of such party.

          2.19  Indemnity as to Letters of Credit.  The Borrower hereby agrees
                ---------------------------------                             
to indemnify and hold harmless the Agent and the Banks from and against any and
all claims, damages, losses, liabilities, costs or expenses whatsoever which the
Agent or the Banks may incur or suffer by reason of or in connection with the
execution and delivery or assignment of, or payment under, any Letter of Credit,
except only if and to the extent that any such claim, damage, loss, liability,
cost or expense shall be caused by the willful misconduct or gross negligence of
the Agent or any Bank performing its obligations respecting such Letter of
Credit under this Agreement.  Without limiting the foregoing, the Borrower
further agrees to indemnify and hold harmless the Agent, its officers and
directors, each person who controls the Agent within the meaning of Section 15
of the Securities Act of 1933 or any applicable state securities law and their
respective successors and assigns from and against any and all claims, damages,
losses, liabilities, costs or expenses, joint or several, to which they or any
of them may become subject under any federal or state securities law, rule or
regulation, at common law or otherwise, insofar as such claims, damages, losses,
liabilities, costs or expenses arise out of or are based upon the execution and
delivery by the Agent of any Letters of Credit or the execution and delivery of
any other document in connection therewith (but not including any claims,
damages, losses, liabilities, costs or expenses arising from the gross
negligence or willful misconduct of the Agent). The Borrower upon demand by the
Agent at any time, shall reimburse the Agent for any reasonable legal or other
expenses incurred in connection with investigating or defending against any of
the foregoing. The indemnities contained herein shall survive the expiration or
termination of the Letters of Credit and this Agreement.

          2.20  Letter of Credit Fees.  The Borrower agrees to pay to the Agent
                ---------------------                                          
its standard draw fees and commissions in effect from time to time.

                                      (23)

          2.21  Acceptance Drafts.
                ----------------- 

          (a) Upon the terms and conditions hereof, the Borrower may, from time
to time from the date hereof until the Termination Date, request the Banks to
accept drafts in the form of Exhibit B (each an "Acceptance Draft" and,
collectively, the "Acceptance Drafts"), at the Borrower's election.

          (b) The Borrower shall give the Agent telephonic notice (immediately
confirmed in writing) of its request that the Agent accept such Acceptance Draft
no later than 1:00 p.m. (Philadelphia time) on the same day of such request (the
"Acceptance Date"). Such notice shall contain the aggregate face amount (which
shall be in minimum aggregate principal amounts of $1,000,000 and in integral
multiples of $100,000 in excess thereof) and maturity date of such Acceptance
Draft, which maturity date shall not be later than the earlier of (a) 30, 60, 90
or 120 days after the Acceptance Date of such Acceptance Draft, as the Borrower
shall designate, and (b) the Termination Date.  Such notices also shall describe
the underlying goods and indicate their origin and destination points or provide
other evidence of the underlying transaction in form and substance as may be
acceptable to the Agent to permit it to accurately complete the appropriate
eligibility legend (i.e., "eligibility certificate") on the face of the
Acceptance Draft. The Borrower shall promptly confirm such telephonic notices by
telecopy and mailing an original signed notice.  Each draft shall mature on a
Business Day, which shall be at least thirty (30) days after the Acceptance
Date.  No Acceptance Draft shall be dated or accepted more than thirty (30) days
before or more than thirty (30) days after the date of the shipment of goods to
which it relates. The Borrower hereby irrevocably authorizes the Agent to
complete its Acceptance Draft in accordance with the instructions given pursuant
to this Section 2.21. Any pre-signed drafts held by the Agent for completion
shall not be affected by the departure of the signer as an authorized signatory
of the Borrower, which drafts shall nevertheless remain valid and binding upon
the Borrower for all purposes as if the signer's authority had continued in
effect. (Such completion and presentment, however, shall not obligate the Agent
to accept any such Acceptance Draft.)

          (c) Upon receipt of such notices from the Borrower, the Agent shall
promptly notify each Bank of (i) its pro rata (based on its Revolving Credit
Commitment) share of such Acceptance Draft, 

                                      (24)
<PAGE>
 
(ii) the maturity date of such Acceptance Draft and (iii) the discount rate and
commission applicable to such Acceptance Draft. The Agent may decline to create
any such Acceptance Draft if the Agent is not then providing such financing to
its middle market customers with credit standings similar to the Borrower's.

          (d) The Agent in its discretion at any time or from time to time may
sell, rediscount or otherwise dispose of any Acceptance Draft without any notice
or credit to or consent from the Borrower or any other Bank.

          (e) Each Acceptance Draft shall relate to one or more specific
transactions involving the importation or exportation of goods or the domestic
shipment of goods within the United States. The goods relating to each
Acceptance Draft shall have a c.i.f. value equalling or exceeding the amount of
the Acceptance Draft, shall be of good and merchantable quality, shall be fully
insured in accordance with prudent industry practice and shall not be the
subject of any security interest granted by the Borrower or any Subsidiary.  No
other source shall have financed the transaction underlying the Acceptance
Draft.  The Borrower shall have procured all import, export and other licenses
essential to the underlying transaction and shall have complied with all
applicable laws pertaining to the underlying goods and transaction.  Each
Acceptance Draft shall qualify (upon acceptance) in all respects with the
requirements for eligibility for discount of the Federal Reserve Banks of the
United States.  With regard to each Acceptance Draft presented, the Borrower
represents and warrants to the Agent and the Banks that, as of the date of
presentment, the Acceptance Draft and underlying goods and transaction conform
to the requirements of this subsection, and the Borrower covenants and agrees
that they will continue to conform to those requirements for so long as the
Acceptance Draft is outstanding.

          2.22  Payment in Respect of Letters of Credit and Acceptances;
                --------------------------------------------------------
Reimbursement.  Upon the issuance of any Letter of Credit, the Agent shall
-------------                                                             
notify each Bank of the principal amount, the number, and the expiration date
thereof and the amount of such Bank's participation therein.  By the issuance of
a Letter of Credit hereunder and without further action on the part of the Agent
or the Banks, each Bank hereby accepts from the Agent a participation (which
participation shall be nonrecourse to the Agent) in such Letter of Credit equal
to such Bank's pro rata 

                                      (25)
<PAGE>
 
(based on its Revolving Credit Commitment) share of such Letter of Credit,
effective upon the issuance of such Letter of Credit. The Agent shall notify
each Bank of the presentment to the Agent of any draft for acceptance hereunder,
which notice shall include the amount of such draft and the maturity date
thereof. Upon the acceptance of any Acceptance Draft, the Agent shall: (i)
notify each Bank of the net proceeds thereof and the amount of such Banks's
participation therein (acquired pursuant to the terms hereof) and (ii) credit
the net proceeds thereof to the Borrower's account maintained with the Agent for
such purpose. Such net proceeds shall be in an amount equal to the face amount
of such Acceptance Draft less the applicable discount and commission. The funds,
net of such discounts and commissions, so credited to the Borrower's account
shall be immediately available to the Borrower, and the Agent shall promptly
notify the Borrower as to the amount of the net funds so credited. By acceptance
of an Acceptance Draft and without further action on the part of the Agent or
the Banks, each Bank hereby accepts from the Agent a participation (which
participation shall be nonrecourse to the Agent) in such Acceptance Draft equal
to such Bank's pro rata (based on its Revolving Credit Commitment) share of such
Acceptance Draft, effective upon the issuance of such Acceptance Draft. Each
Bank hereby absolutely and unconditionally assumes, as primary obligor and not
as a surety, and agrees to pay and discharge, and to indemnify and hold the
Agent harmless from liability in respect of, such Bank's pro rata share of the
amount of any drawing under a Letter of Credit and payment of any Acceptance
Draft. Each Bank acknowledges and agrees that its obligation to acquire
participation in each Letter of Credit issued by and each Acceptance Draft
accepted by the Agent and its obligation to make the payments specified herein,
and the right of the Agent to receive the same, in the manner specified herein,
are absolute and unconditional and shall not be affected by any circumstance
whatsoever, including, without limitation, the occurrence and continuance of a
Default or an Event of Default hereunder, and that each such payment shall be
made without any offset, abatement, withholding or reduction whatsoever. The
Agent shall review, on behalf of the Banks, each draft presented under a Letter
of Credit and shall notify each Bank of any such presentment. Promptly after it
shall have ascertained that any draft presented under such Letter of Credit
appears on its face to be in substantial conformity with the terms and
conditions of the Letter of Credit, the Agent shall give telephonic or facsimile
notice to the Banks and the Borrower of the receipt and amount of 

                                      (26)
<PAGE>
 
such draft and the date on which payment thereon will be made. The Borrower
shall reimburse the Agent for the amount specified in such notice by no later
than 11:00 a.m. (Philadelphia time) on the date such payment is scheduled to be
made. If the Borrower has not so discharged such reimbursement obligations and
the Agent is unable to recover the required amount by debiting the Borrower's
account (as hereinafter provided), the Agent shall give each Bank notice of any
amount that remains unreimbursed, and each Bank shall promptly, but in any event
within two hours of the receipt of such notice, pay the amounts required to the
Agent in immediately available funds, and the Agent, not later than 3:00 p.m.
(Philadelphia time) on such day, shall make the appropriate payment to the
beneficiary. If the Banks shall pay any draft presented under a Letter of Credit
or make any such payment upon the maturity of an Acceptance Draft, then the
Agent, on behalf of the Banks, shall charge the general deposit account of the
Borrower with the Agent for the amount thereof, together with the Agent's
customary overdraft or similar fee in the event the funds available in such
account shall not be sufficient to reimburse the Banks for such payment. If the
Banks have not been reimbursed with respect to such drawing as provided above,
the Borrower shall pay to, the Agent, for the account of the Banks, the amount
of the drawing together with interest on such amount at a rate per annum
(computed on the basis of the actual number of days elapsed over a year of 360
days) equal to the Prime Rate plus 2% payable on demand. The obligations of the
Borrower under this Section 2.22 to reimburse the Banks and the Agent for all
drawings under Letters of Credit and payments made in respect of Acceptance
Drafts shall be absolute, unconditional and irrevocable and shall be satisfied
strictly in accordance with their terms, irrespective of:

          (a) any lack of validity or enforceability of any Letter of Credit or
Acceptance Draft;

          (b) the existence of any claim, setoff, defense or other right which
the Borrower or any other person may at any time have against the beneficiary
under the Letter of Credit or the Acceptance Draft, the Agent or any Bank (other
than the defense of payment in accordance with the terms of this Agreement or a
defense not otherwise waived hereunder based on the gross negligence or willful
misconduct of the Agent or any Bank) or any other person in connection with this
Agreement or any other transaction;

                                      (27)
<PAGE>
 
          (c) any draft or other document presented under any Letter of Credit
or Acceptance Draft proving to be forged, fraudulent, invalid or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;
provided that payment by the Agent or any Bank under such Letter of Credit or
Acceptance Draft against presentation of such draft or document shall not have
constituted gross negligence or willful misconduct;

          (d) payment by the Agent or any Bank under any Letter of Credit
against presentation of a draft or other document which does not comply with the
terms of such Letter of Credit; provided that such payment shall not have
constituted gross negligence or willful misconduct;

          (e) the existence, character, quantity, quality, condition, packing,
value or delivery of any goods or other property relating to any Letter of
Credit or Acceptance Draft;

          (f) the time, place, manner or order in which shipment is made;

          (g) the provisions of any insurance policy or any act or omission of
any insurer, shipper, warehouseman, carrier, correspondent or other person;

          (h) any other circumstance or event whatsoever, whether or not similar
to any of the foregoing; provided that such other circumstance or event shall
not have been the result of gross negligence or willful misconduct of the Agent
or any Bank.

          It is understood that in making any payment under any Letter of Credit
or Acceptance Draft (x) the Agent's and any Bank's exclusive reliance on the
documents presented to it under such Letter of Credit or Acceptance Draft as to
any and all matters set forth therein, including, without limitation, good faith
reliance on the amount of any draft presented under such Letter of Credit or
Acceptance Draft, whether or not the amount due to the beneficiary equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit or Acceptance Draft proves to be insufficient in any respect,
if such document on its face appears to be in order, and whether or not any
other statement or any other document presented pursuant to such Letter of
Credit or Acceptance Draft proves to be forged or invalid or any statement

                                      (28)
<PAGE>
 
therein proves to be inaccurate or untrue in any respect whatsoever and (y) any
noncompliance in any immaterial respect of the documents presented under such
Letter of Credit or Acceptance Draft with the terms thereof shall, in each case,
not be deemed willful misconduct or gross negligence of the Agent or any Bank.

          2.23  Ineligibility of Acceptance Drafts.  In the event that any
                ----------------------------------                        
Acceptance Draft accepted pursuant to this Agreement does not, for reasons
beyond the control of the Agent, comply at the time of its acceptance with
applicable regulations of the Board governing bankers' acceptances and would not
be eligible under such regulations for discount with a Federal Reserve lender or
if for any other reason any Acceptance Draft is deemed by the Agent not eligible
for discount, the Borrower will, upon receipt of written notice from the Agent,
forthwith pay to the Agent any additional cost or costs, as determined by the
Agent, incurred by the Agent (including, without limitation, any costs resulting
from a higher discount rate upon disposition of such Acceptance Draft by the
Agent, any funding costs resulting from a higher discount rate upon disposition
of such Acceptance Draft by the Agent, reserve requirements or additional
premium liability to the Federal Deposit insurance Corporation) in connection
with such Acceptance Draft on account of such noncompliance or ineligibility.

                   SECTION 3.  REPRESENTATIONS AND WARRANTIES
                               ------------------------------

          In order to induce the Agent and the Banks to enter into this
Agreement and to make the Revolving Credit Loans and to issue Letters of Credit
and to create Acceptance Drafts herein provided for, the Borrower hereby
covenants, represents and warrants to the Agent and the Banks that:

          3.1  Financial Condition.  The consolidated balance sheet and
               -------------------                                     
consolidated statements of income, retained earnings and cash flows of the
Borrower and its Subsidiaries as at February 28, 1996 audited by Lazar Levine &
Company, LLC, CPAs, and the interim consolidated balance sheet and consolidated
related statements of income, retained earnings and cash flows of the Borrower
and its Subsidiaries as at November 30, 1996 certified as true and correct by
the chief financial officer of the Borrower, have heretofore been furnished to
the Banks, and fairly present the financial condition of the Borrower and its
Subsidiaries as at such dates, and for the fiscal year and fiscal quarter,
respectively, then ended.  Such annual financial statements have been prepared
in accordance with GAAP and, such interim financial statements have been
prepared on a basis consistent with the annual financial statements, subject to
year end adjustments.  Neither the Borrower nor its Subsidiaries has any
material contingent obligations, contingent liabilities or liability for taxes,
long-term lease or unusual forward or long-term commitment, which are not
reflected in the foregoing statements or in the notes thereto.

          3.2   No Change.  Since November 30, 1996 there has been no material
                ---------                                                     
adverse change in the business, operations, assets or financial or other
condition of the Borrower or its Subsidiaries.

          3.3  Corporate Existence; Compliance with Law; Subsidiaries.  The
               ------------------------------------------------------      
Borrower and each of its Subsidiaries (i) is duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation,
(ii) has the corporate power and authority and the legal right to own and
operate its properties, and to conduct the business in which it is currently
engaged, (iii) does not own or operate properties or conduct business which
requires qualification as a foreign corporation in any jurisdiction in which it
is not so qualified, and (iv) is in compliance with all Requirements of Law;
except to the extent that the failure to so qualify as a foreign corporation 

                                      (30)
<PAGE>
 
as required by clause (iii) of this Section 3.3 or to comply with all
Requirements of Law as required by clause (iv) of this Section 3.3 would not, in
the aggregate, have a material adverse effect on the business, operations,
property or financial or other condition of the Borrower and its Subsidiaries
taken as a whole, and would not materially adversely affect the ability of the
Borrower or a Subsidiary to perform its obligations under this Agreement and the
Revolving Credit Notes.

          3.4  Corporate Power; Authorization; Enforceable Obligations.  The
               -------------------------------------------------------

Documents and to borrow hereunder.  The Borrower has taken all necessary
corporate action to authorize the borrowings hereunder on the terms and
conditions of this Agreement and the Borrower and each of its Subsidiaries has
taken all necessary corporate action to authorize the execution, delivery and
performance of the Loan Documents.  No consent or authorization of, filing with,
or other act by or in respect of any other Person (including stockholders and
creditors of the Borrower or its Subsidiaries) or any Governmental Authority, is
required in connection with the borrowings hereunder or with the execution,
delivery, performance, validity or enforceability of the Loan Documents.  Each
of the Loan Documents has been duly executed and delivered on behalf of the
Borrower or its Subsidiaries as applicable, and each of the Loan Documents
constitutes a legal, valid and binding obligation of the Borrower or its
Subsidiaries as applicable enforceable against the Borrower or its Subsidiaries
as applicable, in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally.

          3.5  Legal Bar.  The execution, delivery and performance of each of
               ---------                                                     
the Loan Documents and the borrowings hereunder and the use of the proceeds
thereof, will not violate any of the Requirements of Law or Contractual
Obligations of the Borrower or its Subsidiaries, and will not result in, or
require the creation or imposition of any Lien on any of its respective
properties or revenues pursuant to any Requirements of Law or Contractual
Obligations except those in favor of the Banks as provided herein.

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

or against the Borrower or any Subsidiary or any of its respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) which if adversely
determined, would have a material adverse effect on the business, operations,
property or financial or other condition of the Borrower and its Subsidiaries
taken as a whole.

in default under or with respect to any Contractual Obligations in any respect
which would be materially adverse to the business, operations, property or
financial or other condition of the Borrower and its Subsidiaries taken as whole
or which would materially and adversely affect the ability of the Borrower or
its Subsidiaries to perform its respective obligations under any of the Loan
Documents.  No Default or Event of Default has occurred and is continuing.

          3.8  No Burdensome Restrictions.  No Contractual  Obligations of the
               --------------------------                                     
Borrower or its Subsidiaries and no Requirements of Law materially adversely
affect, or insofar as the Borrower or its Subsidiaries may reasonably foresee
may so affect, the business, operations, property or financial or other
condition of the Borrower and its Subsidiaries taken as a whole.

          3.9  Federal Regulations.  Neither the Borrower nor its Subsidiaries

is engaged nor will it engage, principally or as one of its important
activities, in the business of extending credit for the purpose of "purchasing"
or "carrying" any "margin stock" within the respective meanings of each of the
quoted terms under Regulation U of the Board of Governors of the Federal Reserve
System as now and from time to time hereafter in effect.  No part of the
proceeds of any Revolving Credit Loans hereunder will be used for "purchasing"
or "carrying" "margin stock" as so defined or for any purpose which violates, or
which would be inconsistent with the provisions of the regulations of such Board
of Governors.

          3.10 Environmental Regulation.
               ------------------------ 

               (a) The Borrower has no knowledge of receipt of any past, pending
or threatened:

              Subsidiaries taken as a whole; or

         (ii) complaints, notices or inquiries to the Borrower or any Subsidiary
              regarding potential liability under any Environmental Law that,
              singly or in the aggregate, have resulted in, or may reasonably be
              expected to result in, any material adverse change in the

              Subsidiaries taken as a whole;

         (b)  No property now or previously owned or leased by the Borrower or

location which is listed or proposed for listing on the National Priorities List
pursuant to CERCLA, on the CERCLIS list or on any similar state list or which is
the subject of federal, state or local enforcement actions or other

remedial work, damage to natural resources or personal injury, including claims
under CERCLA.

          3.12  Taxes.  The Borrower and its Subsidiaries have filed all
                -----

requirements under ERISA with respect to all of its Plans and the present fair
market value of all Plan assets exceeds the present value of all vested benefits
under each Plan, as determined on the most recent valuation date of the Plan in
accordance with the provisions of ERISA and the regulations thereunder for
calculating the potential liability of the Borrower, its Subsidiaries and each
ERISA Affiliate to the PBGC or the Plan under Title IV of ERISA, and neither the
Borrower, its Subsidiaries nor an ERISA Affiliate has incurred any liability to

such holder or holders) to cause such indebtedness to become due prior to its
stated maturity; or

          (f) (i) The Borrower or any of its Subsidiaries shall commence any

          In order to expedite the transactions contemplated by this Agreement,
Mellon Bank, N.A. is hereby appointed to act as Agent on behalf of the Banks.
Each of the Banks and each subse quent holder of any Revolving Credit Note or
issuer of any Letter of Credit, irrevocably authorizes the Agent to take such
action on its behalf and to exercise such powers hereunder and under the Loan
Documents as are specifically delegated to or required of the Agent by the terms
hereof and the terms thereof together with such powers as are reasonably
incidental thereto.  Neither the Agent nor any of 

                                      (54)
<PAGE>
 
its directors, officers, employees or agents shall be liable as such for any
action taken or omitted to be taken by it or them hereunder or under any of the
Loan Documents or in connection herewith or therewith (a) at the request or with
the approval of the Banks (or, if otherwise specifically required hereunder or
thereunder, the consent of the Banks) or (b) in the absence of its or their own
gross negligence or willful misconduct.

          The Agent is hereby expressly authorized on behalf of the Banks,
without hereby limiting any implied authority, (a) to receive on behalf of each
of the Banks any payment of principal of or interest on the Revolving Credit
Notes outstanding hereunder and all other amounts accrued hereunder paid to the
Agent, and promptly to distribute to each Bank its proper share of all payments
so received, (b) to distribute to each Bank copies of all notices, agreements
and other material as provided for in this Agreement or in the other Loan
Documents as received by such Agent and (c) to take all actions with respect to

of or interest on any Revolving Credit Note, any amount payable under any Letter
of Credit or Acceptance Draft, or any fee payable hereunder or (b) the Agent
receives written notice of the occurrence of a Default or an Event of Default,
the Agent within a reasonable time shall give written notice thereof to the
Banks; and shall take such action with respect to such Event of Default or other
condition or event as it shall be directed to take by the Banks; provided,
however, that, unless and until the Agent shall have received such directions,
the Agent may take such action or refrain from taking such action hereunder or
under any other Loan Documents with respect to a Default or Event of Default as
it shall deem advisable in the best interests of the Banks.

          The Agent shall not be responsible in any manner to any of the Banks
for the effectiveness, enforceability, perfection, value, genuineness, validity
or due execution of this Agreement, the Revolving Credit Notes or any of the
other Loan Documents or any other agreements or certificates, requests,
financial statements, notices or opinions of counsel or for any recitals,
statements, warranties or representations contained herein or in any such
instrument or be under any obligation to ascertain or inquire as to the
performance or observance of any of the terms, 

                                      (55)
<PAGE>
 
provisions, covenants, conditions, agreements or obligations of this Agreement
or any of the other Loan Documents or any other agreements on a part of the
Borrower and, without limiting the generality of the foregoing, the Agent shall,
in the absence of knowledge to the contrary, be entitled to accept in good faith
any certificate furnished pursuant to this Agreement or any of the other Loan
Documents as conclusive evidence of the facts stated therein and shall be
entitled to rely in good faith on any note, notice, consent, certificate,
affidavit, letter, telegram, teletype message, statement, order or other
document which it believes in good faith to be genuine and correct and to have
been signed or sent by the proper person or persons. It is understood and agreed
that the Agent may exercise its rights and powers under other agreements and
instruments to which it is or may be a party, and engage in other transactions
with the Borrower, as though it were not Agent of the Banks hereunder.

          The Agent shall promptly give notice to the Banks of the receipt or
sending of any notice, schedule, report, projection, financial statement or
other document or information pursuant to this Agreement or any of the other
Loan Documents and shall promptly forward a copy thereof to each Bank.

          Neither the Agent nor any of its directors, officers, employees or
agents shall have any responsibility to the Borrower on account of the failure
or delay in performance or breach by any Bank other than the Agent of any of its
obligations hereunder or to any Bank on account of the failure of or delay in
performance or breach by any other Bank or the Borrower of any of their
respective obligations hereunder or in connection herewith.

          The Agent may consult with legal counsel selected by it in connection
with matters arising under this Agreement or any of the other Loan Documents and
any action taken or suffered in good faith by it in accordance with the opinion
of such counsel shall be full justification and protection to it.  The Agent may
exercise any of its powers and rights and perform any duty under this Agreement
or any of the other Loan Documents through agents or attorneys.

          The Agent and the Borrower may deem and treat the payee or most recent
assignee pursuant to Section 10.3 hereof, as applicable, of any Revolving Credit
Note as the holder thereof 

                                      (56)
<PAGE>
 
until written notice of transfer shall have been delivered as provided in
Section 10.3 hereof by such payee to the Agent and the Borrower.

          With respect to the Revolving Credit Loans made hereunder, the
Revolving Credit Notes issued to it and any other extension of credit applicable
to it, the Agent in its individual capacity and not as an Agent shall have the
same rights, powers and duties hereunder and under any other Agreement executed
in connection herewith as any other Bank and may exercise the same as though it
were not the Agent, and the Agent and its affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Borrower or
other affiliate thereof as if it were not the Agent.

          Each Bank agrees (i) to reimburse the Agent in the amount of such
Bank's pro rata share (based on its Revolving Credit Commitment hereunder) of
any expenses incurred for the benefit of the Banks by the Agent, including
counsel fees and compensation of agents and employees paid for services rendered
on behalf of the Banks, not reimbursed by the Borrower and (ii) to indemnify and
hold harmless the Agent and any of its directors, officers, employees or agents,
on demand, in the amount of its pro rata share, 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 it in its capacity as the Agent or
any of them in any way relating to or arising out of this Agreement or any of
the other Loan Documents or any action taken or omitted by it or any of them
under this Agreement or any of the other Loan Documents, to the extent not
reimbursed by the Borrower; provided, however, that no Bank shall be liable to
the Agent for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or willful misconduct of the Agent or any of its
directors, officers, employees or agents.

          Each Bank acknowledges that it has, independently and without reliance
upon the Agent or any other Bank and based on such documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement and any other Loan Document to which such Bank is a party.
Each Bank 

                                      (57)
<PAGE>
 
also acknowledges that it will, independently and without reliance upon the
Agent or any other Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own decisions in taking or
not taking action under or based upon this Agreement, any other Loan Document,
any related agreement or any document furnished hereunder.

          Subject to the appointment and acceptance of a successor Agent as
provided below, the Agent may resign at any time by notifying the Banks and the
Borrower.  Upon any such resignation, the Banks shall have the right to appoint
a successor Agent.  If no successor Agent shall have been so appointed by such
Banks and shall have accepted such appointment within thirty (30) days after the
retiring Agent gives notice of its resignation, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent which shall be a bank with an
office (or an affiliate with an office) in the New York metropolitan area having
a combined capital and surplus of at least $500,000,000.  Upon the acceptance of
any appointment as Agent hereunder by a successor bank, such successor shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent and the retiring Agent shall be discharged from
its duties and obligations hereunder and under each of the other Loan Documents.
After any Agent's resignation hereunder, the provisions of this Article shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Agent.

          The Banks hereby acknowledge that the Agent shall be under no duty to
take any discretionary action permitted to be taken by the Agent pursuant to the
provisions of this Agreement or any of the other Loan Documents unless it shall
be requested in writing to do so by the Required Banks.

           10.3  Successors and Assigns: Participations.
                 -------------------------------------- 

          (a) Whenever in this Agreement any of the parties hereto is referred
to, such reference shall be deemed to include the successors and assigns of such
party; and all covenants, promises and agreements by or on behalf the Borrower,
any Guarantor, any ERISA Affiliate, any Subsidiary of any thereof, the Agent or
the Banks, that are contained in this Agreement shall bind and inure to the
benefit of their respective successors and assigns. Without limiting the
generality of the foregoing, the Borrower specifically confirms that the Agent
and each Bank may at any time and from time to time assign or pledge or
otherwise grant a security interest in any Revolving Credit Loan or any
Revolving Credit Note or Acceptance Draft (or any part thereof) to any Federal
Reserve Bank. The Borrower may not assign or transfer any of its rights or
obligations hereunder without the written consent of all the Banks.

          (b) Each Bank, without the consent of the Borrower, may sell
participations to one or more banks or other entities in all or a portion of its
rights and obligations under this Agreement (including, without limitation, all
or a portion of its Revolving Credit Commitment) and the Revolving Credit Loans
owing to it and undrawn Letters of Credit and Acceptance Drafts and the
Revolving Credit Notes held by it); provided, however, that (i) such Bank's
obligations under this Agreement (including, without limitation, its Revolving
Credit Commitment) shall remain unchanged, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) the banks or other entities buying participations shall be entitled to the
cost protection provisions contained in Sections 2.10 (except to the extent that
application of such Section 2.10 to such banks and entities would cause the
Borrower to make duplicate payments thereunder) and Section 2.7 hereof, and (iv)
the Borrower, the Agent and the other Banks shall continue to deal solely and
directly with such Bank in connection with such Bank's rights and obligations
under this Agreement.

          (c) Each Bank may assign by novation as of the date of assignment, to
any one or more banks or other entities with the consent of the Borrower (which
consent shall be given in its sole discretion unless the Agent waives its
additional fee for the assignment to such bank or banks in which case consent
will not be unreasonably withheld) and the Agent (which consent will not be

                                      (60)
<PAGE>
 
unreasonably withheld) (except that in the case of an assignment by a Bank to
one of its Affiliates or to another Bank no such consent of the Agent shall be
required), all or a portion of its interests, rights and obligations under this
Agreement and the other Loan Documents (including, without limitation, all or a
portion of its Revolving Credit Commitment and the same portion of the Revolving
Credit Loans and undrawn Letters of Credit and Acceptance Drafts at the time
owing to it and the Revolving Credit Note held by it), provided, however, that
(i) each such assignment shall be of a constant, and not a varying, percentage
of all of the assigning Bank's rights and obligations under this Agreement,
which shall include the same percentage interest in the Revolving Credit Loans,
Letters of Credit, Acceptance Drafts and Revolving Credit Notes, (ii) the amount
of the Revolving Credit Commitment of the assigning Bank being assigned pursuant
to each such assignment (determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Agent) shall be in a minimum
principal amount of $3,000,000 Revolving Credit Commitment of such Bank and
(iii) the parties to each such assignment shall execute and deliver to the
Agent, for its acceptance and recording in the Register (as defined below), an
assignment and acceptance in form and substance acceptable to the Agent (an
"Assignment and Acceptance"), together with any Revolving Credit Note subject to
such assignment and a processing and recordation fee of $2,500.00 payable by the
assigning Bank. Upon such execution, delivery, acceptance and recording and
after receipt of the written consent of the Agent, from and after the effective
date specified in each Assignment and Acceptance, which effective date shall be
at least five (5) Business Days after the execution thereof, (x) the assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Bank hereunder
and under the other Loan Documents and (y) the Bank which is assignor thereunder
shall, to the extent provided in such Assignment and Acceptance, be released
from its obligations under this Agreement and the other Loan Documents (and, in
the case of an Assignment and Acceptance covering all or the remaining portion
of an assigning Bank's rights and obligations under this Agreement, such Bank
shall cease to be a party hereto and thereto).

          (d) By executing and delivering an Assignment and Acceptance, the Bank
which is assignor thereunder and the assignee thereunder confirm to, and agree
with, each other and the other 

                                      (61)
<PAGE>
 
parties hereto as follows: (i) other than the representation and warranty that
it is the legal and beneficial owner of the interest being assigned thereunder
free and clear of any adverse claim, responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, perfection,
genuineness, sufficiency or value of this Agreement, the other Loan Documents or
any other instrument or document furnished pursuant hereto or thereto; (ii) such
Bank makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower, any Guarantor or any
Subsidiary of any thereof or the performance or observance by the Borrower, any
Guarantor or any Subsidiary of any thereof of any of their respective
obligations under this Agreement or any of the other Loan Documents or any other
instrument or document furnished pursuant hereto or thereto; (iii) such assignee
confirms that it has received a copy of this Agreement, and the other Loan
Documents, together with copies of financial statements and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such Bank or any other Bank
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and authorizes the Agent to
take such action as the Agent on its behalf and to exercise such powers under
this Agreement as are delegated to the Agent by the terms hereof, together with
such powers as are reasonably incidental thereto; and (vi) such assignee agrees
that it will perform in accordance with their terms all of the obligations which
by the terms of this Agreement are required to be performed by it as a Bank.

          (e) The Agent shall maintain at its address referred to in Section
10.1 hereof a copy of each Assignment and Acceptance delivered to it and a
register for the recordation of the names and addresses of the Banks and the
Revolving Credit Commitment of, and principal amount of the Loans owing to, each
Bank from time to time (the "Register").  The entries in the Register shall be
conclusive, in the absence of manifest error or written notice to the contrary
delivered in accordance with this Agreement, and the Borrower, the Agent and the
Banks may treat each person whose name is so recorded in the Register as a Bank
hereunder for all purposes of this 

                                      (62)
<PAGE>
 
Agreement. The Register shall be available for inspection by the Borrower or any
Bank at any reasonable time and from time to time upon reasonable prior notice.

          (f) Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and an assignee together with any Revolving Credit Note subject
to such assignment and the written consent to such assignment, the Agent shall
(i) accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register and (iii) give prompt notice thereof to the Banks and
the Borrower.  Within five (5) Business Days after receipt of such notice, the
Borrower, at its own expense, shall execute and deliver to the Agent in exchange
for each surrendered Note or Notes a new Revolving Credit Note to the order of
such assignee in an amount equal to the Revolving Credit Commitment assumed by
it pursuant to such Assignment and Acceptance and, if the assigning Bank has
retained any Revolving Credit Commitment hereunder, a new Revolving Credit Note
to the order of the assigning Bank in an amount equal to the Revolving Credit
Commitment retained by it hereunder.  Such new Revolving Credit Note shall be in
an aggregate principal amount equal to the aggregate principal amount of such
surrendered Revolving Credit Note shall be dated the effective date of such
Assignment and Acceptance and shall otherwise be in substantially the form of
Exhibit A hereto.

          (g) Notwithstanding any other provision herein, any Bank may, in
connection with any assignment or participation or proposed assignment or
participation pursuant to this Section 10.03, disclose to the assignee or
participant or proposed assignee or participant, any information relating to the
Borrower furnished to such Bank by or on behalf of the Borrower in connection
with this Agreement; provided, however, that prior to any such disclosure,
each such assignee or participant or proposed assignee or participant shall
agree to preserve the confidentiality of any confidential information relating
to the Borrower received from such Bank.

          (h) Nothing in this Section shall limit or restrict the ability of any
Bank to sell, rediscount or otherwise dispose of any Acceptance Draft.

                                      (63)

          (i) The annual Agent's fee shall be payable in accordance with the
provisions of Section 5.11 hereof.

           10.4  Expenses: Indemnity.
                 ------------------- 

          (a) The Borrower agrees to pay all reasonable out-of-pocket expenses
incurred by the Agent in connection with the preparation of this Agreement, the
Revolving Credit Notes and the other Loan Documents or with any amendments,
modifications or waivers of the provisions hereof or thereof or incurred by the
Agent or any of the Banks in connection with the enforcement, adjudication or
protection of its rights in connection with this Agreement or any of the other
Loan Documents or with the Loans made or the Revolving Credit Notes or Letters
of Credit or Acceptance Drafts issued hereunder, or in connection with any
pending or threatened action, proceeding, or investigation relating to the
foregoing, including but not limited to the reasonable fees and disbursements of
counsel for the Agent and, in connection with such enforcement or protection,
the reasonable fees and disbursements of counsel for the Banks.  The Borrower
further indemnifies the Banks from and agrees to hold them harmless against any
documentary taxes, assessments or charges made by any governmental authority by
reason of the execution and delivery of this Agreement or the Revolving Credit
Notes.

          (b) The provisions of this Section 10.4 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Revolving Credit Loans, the invalidity or
unenforceability of any term or provision of this Agreement or the Notes, or any
investigation made by or on behalf of the Agent or any Bank.  All amounts due
under this Section 10.04 shall be payable on written demand therefor.

          10.5  Applicable Law.  THIS AGREEMENT AND THE REVOLVING CREDIT NOTES
                --------------                                                
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF
NEW YORK.

          10.6  Right of Setoff.  If an Event of Default shall have occurred and
                ---------------                                                 
be continuing, upon the request of the Banks each Bank shall and is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional 

                                      (64)

or final) at any time held and other indebtedness at any time owing by such Bank
to or for the credit or the account of the Borrower or any Guarantor against any
and all of the obligations of the Borrower now or hereafter existing under this
Agreement and the Revolving Credit Notes held by such Bank, irrespective of
whether or not such Bank shall have made any demand under this Agreement or the
Revolving Credit Notes and although such obligations may be unmatured. Each Bank
agrees to notify promptly the Agent and the Borrower and any applicable
Guarantor after any such setoff and application made by such Bank, but the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of each Bank under this Section are in addition to other
rights and remedies (including, without limitation, other rights of setoff)
which may be available to such Bank.

          10.7  Payments on Business Days.  Should the principal of or interest
                -------------------------                                      
on the Revolving Credit Notes or any fee or other amount payable hereunder
become due and payable on other than a Business Day, payment in respect thereof
may be made on the next succeeding Business Day (except as otherwise specified
in the definition of "Interest Period"), and such extension of time shall in
such case be included in computing interest, if any, in connection with such
payment.

           10.8  Waivers; Amendments.
                 ------------------- 

          (a)  No failure or delay of any Bank in exercising any power or right
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such right or power, preclude any other or further exercise
thereof or the exercise of any other right or power.  The rights and remedies of
the Bank hereunder are cumulative and not exclusive of any rights or remedies
which they may otherwise have.  No waiver of any provision of this Agreement or
the Revolving Credit Notes nor consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be authorized as
provided in paragraph (b) below, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.  No
notice to or demand on the Borrower in any case shall entitle it to any other or
further notice or demand in similar or other circumstances.  Each holder of any
of the Revolving Credit Notes shall be bound by any amendment, 

                                      (65)
<PAGE>
 
modification, waiver or consent authorized as provided herein, whether or not
such Revolving Credit Note shall have been marked to indicate such amendment,
modification, waiver or consent.

          (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower, the Agent and the Banks.  Each Bank and holder of
any Revolving Credit Note shall be bound by any modification or amendment
authorized by this Section regardless of whether its Revolving Credit Note shall
be marked to make reference thereto, and any consent by any Bank or holder of a
Revolving Credit Note pursuant to this Section shall bind any person
subsequently acquiring a Revolving Credit Note from it, whether or not such
Revolving Credit Note shall be so marked.

          10.9  Severability.  In the event any one or more of the provisions
                ------------                                                 
contained in this Agreement or in the Revolving Credit Notes should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein or therein shall not
in any way be affected or impaired thereby.  The parties shall endeavor in good
faith negotiations to replace the invalid, illegal or unenforceable provisions
with valid provisions the economic effect of which comes as close as possible to
that of the invalid, illegal or unenforceable provisions.

           10.10  Entire Agreement; Waiver of Jury Trial, Etc.
                  ------------------------------------------- 

          (a) This Agreement, the Revolving Credit Notes and the other Loan
Documents constitute the entire contract between the parties hereto relative to
the subject matter hereof.  Any previous agreement among the parties hereto with
respect to the transactions contemplated hereby is superseded by this Agreement,
the Revolving Credit Notes and the other Loan Documents.  Except as expressly
provided in this Agreement, the Revolving Credit Notes or the other Loan
Documents, nothing in this Agreement, the Revolving Credit Notes or in the other
Loan Documents is intended to confer upon any party, other than the parties
hereto, any rights, remedies, obligations or liabilities under or by reason of
this Agreement, the Notes or the other Loan Documents.

          (b) THE BORROWER HEREBY EXPRESSLY WAIVES ANY AND EVERY RIGHT TO A
TRIAL BY JURY IN ANY ACTION ON OR RELATED TO ANY OF THE 

                                      (66)
<PAGE>
 
LOAN DOCUMENTS OR THE ENFORCEMENT OF ANY OR ALL OF THE SAME. THE BORROWER HEREBY
EXPRESSLY WAIVES ANY RIGHT TO INTERPOSE A COUNTERCLAIM IN ANY ACTION OR
PROCEEDING ON OR RELATED TO THIS AGREEMENT EXCEPT FOR MANDATORY COUNTERCLAIMS.

          (c) Each party hereto (i) certifies that no representative, agent or
attorney of any Bank has represented, expressly or otherwise, that such Bank
would not, in the event of litigation, seek to enforce the foregoing waivers and
(ii) acknowledges that it has been induced to enter into this Agreement, the
Revolving Credit Notes or the other Loan Documents, as applicable, by, among
other things, the mutual waivers and certifications herein.

          10.11  Confidentiality.  The Agent and the Banks agree to keep
                 ---------------                                        
confidential (and to cause their respective officers, directors, employees,
agents and representatives to keep confidential) all information, materials and
documents furnished to the Agent or any Bank (the "Information").
Notwithstanding the foregoing, the Agent and each Bank shall be permitted to

attorneys and representatives as need to know such Information in connection
with its participation in any of the Transactions or the administration of this
Agreement or the other Loan Documents; (ii) to the extent required by applicable
laws and regulations or by any subpoena or similar legal process, or requested
by any governmental agency or authority; (iii) to the extent such Information
(A) becomes publicly available other than as a result of a breach of this

basis from a source other than the Borrower, any Guarantor or any of their
respective subsidiaries or (C) was available to the Agent or such Bank on a non-
confidential basis prior to its disclosure to the Agent or such Bank by the
Borrower, any Guarantor or any of their respective subsidiaries; (iv) to the
extent the Borrower, any Guarantor or any of their respective subsidiaries shall
have consented to such disclosure in writing; (v) in connection with the sale of
any collateral pursuant to the provisions of any of the other Loan Documents; or
(vi) pursuant to subsection 10.3(g) hereof.

           10.12  Submission to Jurisdiction.

the Revolving Credit Notes or any other Loan Document may be brought in the

the Borrower and each of the Guarantors hereby accept for themselves and in
respect of their property, generally and unconditionally, the jurisdiction of
the aforesaid courts.

          (b) The Borrower and each of the Guarantors hereby irrevocably waive,
in connection with any such action or proceeding, any objection, including,
without limitation, any objection to the laying of venue or based on the grounds
of forum non conveniens, which they may now or hereafter have to the bringing of
any such action or proceeding in such respective jurisdictions.

          (c) The Borrower and each of the Guarantors hereby irrevocably consent
to the service of process of any of the aforementioned courts in any such action
or proceeding by the mailing of copies thereof by registered or certified mail,

          (d) Nothing herein shall affect the right of the Agent or any Bank to

proceedings or otherwise proceed against the Borrower or any Guarantor in any
other jurisdiction.

          10.13  Further Assurances.  The Borrower agrees at any time and from
                 ------------------
