     Within the foregoing limits, the Borrower may borrow, repay (or, subject to

Commitment Period, subject to the terms, provisions and limitations set forth
herein.

     2.2  Revolving Credit Loans.  (a)  The Revolving Credit Loans made by a

Lender on any date shall be in a minimum amount of $500,000 and in integral

<PAGE>

in integral multiples of $100,000 in excess thereof in the case of a Prime Rate
Loan.

          (b) Revolving Credit Loans shall be made ratably by the Lenders in
accordance with their respective Revolving Credit Commitments; provided,
however, that the failure of any Lender to make any Revolving Credit Loan shall
not in itself relieve any other Lender of its obligation to lend hereunder.

          (c) Each Revolving Credit Loan shall be either a Prime Rate Loan or a
LIBOR Rate Loan as the Borrower may request pursuant to Section 2.5 hereof.
Loans of more than one type and Interest Period may be outstanding at the same
time.

           (d) Each Lender shall make its Revolving Credit Loans on the proposed
dates thereof by paying the amount required to the Administrative Agent in
Philadelphia, Pennsylvania in immediately available funds not later than 12:00
noon, Philadelphia time, and the Administrative Agent shall as soon as
practicable, but in no event later than 3:00 p.m., Philadelphia time, credit the
amounts so received to the general deposit account of the Borrower with the
Administrative Agent in immediately available funds or, if Revolving Credit
Loans are not to be made on such date because any condition precedent to a
borrowing herein specified is not met, return the amounts so received to the
respective Lenders.

     2.2.1 Swing Loans.  (a) Subject to the terms and conditions set forth
           -----------
herein, the Swing Lender agrees to make Swing Loans to the Borrower, in the
Swing Lender's sole discretion, from time to time during the Commitment Period,
in an aggregate principal amount at any time outstanding that will not result in
the aggregate principal amount of outstanding Swing Loans exceeding the Swing
Loan Commitment; provided, however, that no Swing Loan shall be made if, after
giving effect to such Swing Loan, the Aggregate Outstandings would exceed the
Total Revolving Credit Commitment in effect at such time.  Within the foregoing
limit and subject to the Swing Lender's discretion and the terms and conditions
set forth herein, the Borrower may borrow, prepay and reborrow the Swing Loans.
Each Swing Loan shall be made as a Prime Rate Loan.

           (b) To request a Swing Loan, the Borrower shall notify the Swing
Lender (which shall promptly notify the Administrative Agent) of such request by
telephone (confirmed by telecopy), not later than 1:00 p.m., Philadelphia time,
on the day of a proposed Swing Loan.  Each such notice shall be irrevocable and
shall specify the requested date (which shall be a Business Day) of the
requested Swing Loan and the amount of the requested Swing Loan.  The Swing
Lender shall make each Swing Loan available to the Borrower, in its discretion,
by means of a credit to the general deposit account of the Borrower with the
Administrative Agent by

                                       12
<PAGE>

3:00 p.m., Philadelphia time, on the requested date of such Swing Loan.

          (c) The Swing Lender may by written notice given to the Administrative
Agent not later than 12:00 noon, Philadelphia time, on any Business Day require
the Lenders to acquire participations on such Business Day in all or a portion
of the Swing Loans then outstanding.  Such notice shall specify the aggregate
amount of Swing Loans in which Lenders will participate.  Promptly upon receipt
of such notice, the Administrative Agent will give notice thereof to each
Lender, specifying in such notice such Lender's pro rata share of such
outstanding Swing Loan or Loans, which pro rata share shall be based upon the
proportion that such Lender's Revolving Credit Commitment bears to the Total
Revolving Credit Commitment.  Each Lender hereby absolutely and unconditionally
agrees, upon receipt of notice as provided above, to pay to the Administrative
Agent, for the account of the Swing Lender, such Lender's pro rata share of such
Swing Loan or Loans.  Each Lender acknowledges and agrees that its obligation to
acquire participations in Swing Loans pursuant to this paragraph is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or Event of Default or
reduction or termination of the Revolving Credit Commitments, and that each such
payment shall be made without any offset, abatement, withholding or reduction
whatsoever.  Each Lender shall comply with its obligation under this paragraph
in the same manner as provided in Section 2.2(d) hereof with respect to
Revolving Credit Loans made by such Lender and the Administrative Agent shall
promptly pay to the Swing Lender the amounts so received by it from the Lenders.
The Administrative Agent shall notify the Borrower of any participations in any
Swing Loan acquired pursuant to this paragraph, and thereafter payments in
respect of such Swing Loan shall be made to the Administrative Agent and not to
the Swing Lender.  Any amounts received by the Swing Lender from the Borrower
(or other party on behalf of the applicable Borrower) in respect of a Swing Loan
after receipt by the Swing Lender of the proceeds of a sale of participations
therein shall be promptly remitted to the Administrative Agent; any such amounts
received by the Administrative Agent shall be promptly remitted by the
Administrative Agent to the Lenders that shall have made their payments pursuant
to this paragraph and to the Swing Lender, as their interests may appear.  The
purchase of participations in a Swing Loan pursuant to this paragraph shall not
relieve the Borrower of any default in the payment thereof.

          (d) The Swing Loans made by the Swing Lender on any date shall be in a
minimum amount of $250,000.00 and in integral multiples of $100,000.00 in excess
thereof.

          (e) The Swing Loan Commitment shall automatically and permanently
terminate on the Termination Date.

obligations of the Borrower to pay to each Lender on the Termination Date the

Lender, with interest thereon as hereinafter prescribed in Section 2.4 hereof.

          (b) The Swing Loans made by the Swing Lender pursuant to Section 2.2.1

to the Swing Lender on the Termination Date the lesser of (y) $4,000,000.00 or
(z) the aggregate unpaid principal amount of all Swing Loans made by the Swing
Lender, with interest thereon as hereinafter prescribed in Section 2.4 hereof.

          (c) The date and amount of each Loan, the basis for calculating
interest, the Interest Period (if any) applicable thereto and each payment of
principal with respect thereto may be endorsed by the Lenders on the schedule
annexed to and constituting a part of the Notes.  The aggregate unpaid amount of
Loans set forth on such schedule shall be presumed to be the principal amount
owing and unpaid thereon.  The failure of a Lender to make such endorsement on
such schedule shall not prejudice such Lender in any way, nor affect its rights
hereunder with respect to any Loan.  The Notes shall be dated the date of this
Agreement and be stated to mature on the Termination Date.

     2.4  Interest.  Interest on each Revolving Credit Loan shall be at a per
          --------

          (b) subject to availability, the LIBOR Rate for Interest Periods
selected by the Borrower plus the applicable Margin.

The Administrative Agent shall determine each interest rate applicable to the
Revolving Credit Loans and shall promptly advise the Borrower and the Lenders of

Interest on each Prime Rate Loan shall be payable monthly in arrears to

                                       14

the Administrative Agent for the pro rata benefit of the Lenders, or with
respect to Swing Loans, to the Swing Lender on the first Business Day of each
month, commencing on the first such day to occur after the pertinent Loan is
made and upon payment in full thereof. Interest on each LIBOR Rate Loan shall be
payable to the Administrative Agent for the pro rata benefit of the Lenders in
arrears (i) in the case of LIBOR Rate Loans with Interest Periods of three
months or less, at the end of each applicable Interest Period and (ii) in the
case of LIBOR Rate Loans with Interest Periods of more than three months, at the
end of each calendar quarter and at the end of the applicable Interest Period.
Whenever the unpaid principal balance of any Loan shall become due and payable
(whether at the stated maturity thereof, by acceleration or otherwise) interest
shall thereafter be payable, on demand, to the Administrative Agent for the pro
rata benefit of the Lenders at the Involuntary Rate; provided, however, that no
interest payable hereunder shall be in excess of the rate permitted by
applicable law. Interest on each Loan shall be calculated on the basis of a year
of 360 days for the actual number of days elapsed.

not later than 11:00 a.m. (Philadelphia time) on the day which is not less than
the number of Business Days specified above for such notice. Any request for a
conversion or a renewal under this Section 2.6 may be written or oral, but if
oral, it shall be confirmed in writing sent by the Borrower to the
Administrative Agent within two (2) Business Days thereafter. If the Borrower
shall fail to give the Administrative Agent the notice as specified above for
the renewal or conversion of a LIBOR Rate Loan prior to the end of the Interest
Period with respect thereto, such LIBOR Rate Loan shall automatically be
converted into a Prime Rate Loan on the last day of the Interest Period for such
Revolving Credit Loan. The Administrative Agent shall promptly advise (but in
any event, by 2:00 p.m. Philadelphia time, three (3) Business Days prior to a
LIBOR Rate Loan or by 3:00 p.m. on the same Business Day in the case of a Prime
Rate Loan) the Lenders of any notice given pursuant to this Section 2.6 and of
each Lender'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 Administrative 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
Lender of making or maintaining a LIBOR Rate Loan

then the Administrative Agent shall give the Borrower and the Lenders 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, or to borrow or renew, a LIBOR Rate Loan shall be suspended.  The
Borrower, in such event, shall, on the last day of a then current

                                       16
<PAGE>

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 Lender 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 Lender upon notice to the Administrative Agent and the Borrower
and Revolving Credit Loans of such Lender 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 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
          ------------------
Commitments, the Borrower agrees to pay the Administrative Agent for the pro
rata benefit of the Lenders a commitment fee for the Commitment Period based on
the average daily unused portion of the Total Revolving Credit Commitment
(without reference to the Borrowing Base) and the applicable Leverage Ratio and
Liabilities to Tangible Net Worth Ratio as reflected in the financial statements
delivered pursuant to Section 5.1 hereof in the percentage per annum as
determined by reference to the grid set forth below:

Any fee payable under this Section 2.9 which is not paid when due shall bear
interest at the Involuntary 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 or any earlier date of termination in accordance
with the terms of this Agreement.  The "unused portion of the Total Revolving
Credit Commitment" means, at any time, the Total Revolving Credit Commitment
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 Administrative Agent, for the pro rata account of the Lenders,
accrued unused fees on the portion of the Revolving Credit Commitment terminated
or reduced to the date of termination or reduction.

     2.10  Additional Compensation in Certain Circumstances  .
           ------------------------------------------------

           (a) Increased Costs or Reduced Return Resulting From Taxes, Reserves,
               -----------------------------------------------------------------
Capital Adequacy Requirements, Expenses, Etc.  If any law or guideline or
---------------------------------------------
interpretation or application thereof by any Governmental Authority charged with
the interpretation or administration thereof, or any change therein, 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 Administrative Agent or a Lender to any tax or
changes the basis of taxation with respect to this Agreement, the Notes, the
Loans, any other extensions of credit under this Agreement or payments by the
Borrower of principal, interest, commitment fee or other amounts due from the
Borrower hereunder or under the Notes (except for taxes on the overall net
income of the Administrative Agent or a Lender imposed by the jurisdiction in
which the Administrative Agent or such Lender'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 Administrative Agent or a Lender (or
participations in any of the foregoing) (other than requirements expressly
included herein in the determination of the LIBOR Rate hereunder),

                                       18
<PAGE>

               (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 Administrative Agent or a
Lender (or participations therein) or (B) otherwise applicable to the
obligations of the Administrative Agent or a Lender under this Agreement, or

               (iv)  imposes upon the Administrative Agent or a Lender any other
condition or expense with respect to this Agreement, the Notes or its making,
maintenance or funding any part of the Loans or any other extensions of credit
under this Agreement (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
Administrative Agent or a Lender with respect to this Agreement, the Notes or
the making, maintenance or funding of any part of the Loans or any other
extensions of credit under this Agreement (or, in the case of any capital
adequacy or similar requirement, to have the effect of reducing the rate of
return on the Administrative Agent's or a Lender's capital, taking into
consideration the Administrative Agent's and such Lender's policies with respect
to capital adequacy) by an amount which the Administrative Agent or a Lender
deems to be material, the Administrative Agent or such Lender shall from time to
time notify the Borrower of the amount determined in good faith (using any
averaging and attribution methods) by the Administrative Agent or such Lender
(which determination shall be conclusive) to be necessary to compensate the
Administrative Agent or such Lender for such increase, reduction or imposition.
Such amount shall be due and payable by the Borrower to the Administrative Agent
or the applicable Lender ten (10) ten Business Days after such notice is given.
A certificate by the Administrative Agent or a Lender 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 "Lender" shall be deemed to include any participant in such
Lender'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 Administrative Agent
and each Lender against any loss or expense (including loss of margin) which the
Administrative Agent or such Lender 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,

                                       19
<PAGE>

prepayment or conversion is mandatory or automatic and whether or not such
payment or prepayment is then due).

          (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 Administrative 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 Notes, including
without limitation any failure of the Borrower to pay when due (by acceleration
or otherwise) any principal, interest, commitment fee or other amount due
hereunder or under a Note.

If the Administrative Agent or a Lender 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 Administrative Agent or such Lender (which determination
shall be conclusive) to be necessary to indemnify the Administrative Agent or
such Lender for such loss or expense.  Such amount shall be due and payable by
the Borrower to the Administrative Agent or Lender ten (10) Business Days after
such notice is given.

          All references to "Lender" shall be deemed to include any participant
in such Lender'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 Administrative Agent (which shall promptly notify each
of the Lenders), 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 reduce permanently the amount of
the Total Revolving Credit Commitment then in effect, and (iii) shall be
accompanied by prepayment of the 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 Aggregate Outstandings 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

                                       20
<PAGE>

prepayment in full of the Loans outstanding, together with accrued interest
thereon to the date of prepayment, and the payment of any unpaid commitment fee
then accrued hereunder, and (c) no such reduction shall reduce the Total
Revolving Credit Commitment to an amount which is less than the sum of the
Letter of Credit Exposure plus the Acceptance Draft Exposure, and (d) no such
termination shall be effective if there is then any Letter of Credit Exposure or
Acceptance Draft Exposure.

     2.12  Prepayment.  Subject to the indemnity agreement with respect to
           ----------
LIBOR Rate Loans set forth in Section 2.10(b) hereof, the Borrower (a) may
prepay any Loan in whole or in part without premium or penalty and (b) shall
prepay Loans during the Required Borrowing Base Period to the extent that the
Aggregate Outstandings exceed the Borrowing Base.  Each prepayment shall be made
together with interest accrued on the amount prepaid to the date of prepayment.
Prepayments of Loans may be reborrowed on a revolving basis as aforesaid.

     2.13  Payments. (a)  Except as set forth below with respect to Swing
           --------
Loans, 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 Lenders on the date of payment at the
office of the Administrative Agent set forth in Section 10.1 hereof or at such
other place as the Administrative Agent may from time to time designate in
writing on or before 11:00 a.m. (Philadelphia time).  All such payments with
respect to Swing Loans shall be to the Swing Lender.  All such payments shall be
made 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 and, in the
event of any extension, with respect to payments of principal, interest thereon
shall be payable at the then applicable rate during such extension.

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

                                       21
<PAGE>

     2.14  Pro Rata Treatment.  (a) Except for any payment, reimbursement or
           ------------------
other indemnity to any Lender or other indemnified person under Section 2.7(b),
2.10, 2.19 or 10.4 hereof, or under Section 2.4 or 2.13 hereof with respect to
Swing Loans, each borrowing, each payment of any fee or other amount payable
hereunder and each reduction of the Total Revolving Credit Commitment shall be
made pro rata among the Lenders in the proportions that their Revolving Credit
Commitments bear to the Total Revolving Credit Commitment.  Each payment or
prepayment of principal of the Revolving Credit Notes and each payment of
interest on the Revolving Credit Notes shall be made pro rata among the Lenders
in the proportions that the amount outstanding under a Revolving Credit Note
payable to a particular Lender bears to the aggregate amount outstanding under
the Revolving Credit Notes.

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

                                       22
<PAGE>

to the Administrative Agent, the Administrative Agent shall so notify the other
Lender(s) whereupon such Lender(s) shall be required to make such amount
available to the Administrative Agent on a pro rata basis between (or among) the
Lenders 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 Lender's unused Revolving Credit Commitment as set forth on
Schedule A attached hereto.

     2.15  Sharing of Setoffs.  Each Lender 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 Lender 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 or participation in the Swing Loan Note as a result of which the unpaid
principal portion of the Revolving Credit Note held by it or participation in
the Swing Loan Note shall be proportionately less than the unpaid principal
portion of the Revolving Credit Notes or participation in the Swing Loan Note
held by any other Lender, it shall be deemed to have simultaneously purchased
from such other Lender a participation in the Revolving Credit Note or
participation in the Swing Loan Note held by such other Lender with the purchase
price payable in cash upon demand by such other Lender, so that the aggregate
unpaid principal amount of the Revolving Credit Notes and participations in
Revolving Credit Notes and the Swing Loan Note held by it shall be in the same
proportion to the aggregate unpaid principal amount of all Revolving Credit
Notes and the Swing Loan Note then outstanding as the principal amount of the
Revolving Credit Notes and participation in the Swing Loan Note held by it prior
to such exercise of banker's lien, setoff or counterclaim was to the principal
amount of all Revolving Credit Notes and the Swing Loan Note 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 Lender shall thereafter receive or recover from
or respecting the Borrower or any Guarantor any amount in respect of a Revolving
Credit Note or Swing Loan Note proportionally greater than that received by the
first Lender, 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 Lender exceeds the amount necessary to restore the
Lenders respective pro rata shares, then this section shall apply to such
excess.  If all or part of any proportionately greater payment received by any
purchasing Lender is thereafter recovered from

                                       23
<PAGE>

such purchasing Lender upon the bankruptcy or reorganization of the Borrower or
any Guarantor, or otherwise, the purchases by such purchasing Lender shall be
rescinded and the purchase price paid for the participations purchased by such
purchasing Lender shall be returned to such purchasing Lender ratably to the
extent of such recovery, but without interest. The Borrower expressly consents
to the foregoing arrangements and agrees that any Lender holding a participation
in a 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 Lender as fully as if such Lender held a 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 the Administrative
Agent or the lenders named under the revolving credit agreement among the
Administrative Agent and certain lenders and the Borrower dated as of July 12,
2000 (the "Prior Agreement").  Any remaining proceeds of the initial borrowing
and of any subsequent Loans may be used by the Borrower for working capital
purposes, capital expenditures and to fund the purchase price of Permitted
Acquisitions.  Letters of Credit shall be issued by the Issuing Lender hereunder
for the account of the Borrower and shall be issued for the purpose of providing
a payment mechanism in connection with the purchase of any materials, goods or
services by the Borrower or any Guarantors in the ordinary course of their
respective businesses.  Acceptance Drafts shall be utilized to finance the
importation, exportation or domestic shipment of goods.  No portion of the
proceeds of any Loan and no Letter of Credit or Acceptance Draft shall be used
by the Borrower in any manner which might cause the borrowing of such Loan, or
such Letter of Credit or Acceptance Draft, or the application of such proceeds
to violate Regulation U, Regulation T or Regulation X of the Board.

     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 Issuing Lender requires of its customers
generally, the Issuing Lender shall from time to time during the Commitment
Period 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 Issuing Lender which written notice shall be an application for
a Letter of Credit on the Issuing Lender'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.

                                       24
<PAGE>

     2.18  Actions of Issuing Lender.  Any Letter of Credit may, in the
           -------------------------
discretion of the Issuing Lender 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 customs prevailing at the place where any Letter of
Credit is available or the drafts thereunder are drawn or negotiated.  The
Issuing Lender 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 Issuing Lender, the Administrative Agent and the
Lenders from and against any and all claims, damages, losses, liabilities, costs
or expenses whatsoever which the Issuing Lender, the Administrative Agent or the
Lenders 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
Issuing Lender, the Administrative Agent or any Lender 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 Issuing Lender, the Administrative Agent, the Lenders and their
respective officers and directors, each person who controls any of the foregoing
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 Issuing Lender 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 Issuing Lender, the Administrative Agent or a Lender).  The
Borrower upon demand by the Administrative Agent at any time, shall reimburse
the Administrative 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

                                       25
<PAGE>

survive the expiration or termination of the Letters of Credit and this
Agreement.

     2.20  Letter of Credit and Acceptance Draft Fees.  The Borrower agrees to
           ------------------------------------------
pay to the Issuing Lender its standard Letter of Credit draw fees in effect from
time to time, its standard fees in effect from time to time with respect to
Acceptance Drafts and commissions on Letters of Credit in an amount of less than
$500.00.  The Borrower also agrees to pay any Letter of Credit commission or
Acceptance Draft discount in excess of $500.00 to the Administrative Agent.  The
full amount of such commission or discount in excess of $500.00 shall be shared
with the Lenders on a pro rata basis in accordance with the provisions of
Section 2.14 hereof.

     2.21  Acceptance Drafts.  (a)  Upon the terms and conditions hereof, the
           -----------------
Borrower may, from time to time during the Commitment Period, request the
Issuing Lender 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 Issuing Lender telephonic notice
(immediately confirmed in writing) of its request that the Issuing Lender 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) 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 Issuing Lender to permit it to accurately
complete the appropriate eligibility legend (i.e., "eligibility certificate") on
the face of the relevant 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 related  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 Issuing Lender to complete its Acceptance Draft in
accordance with the instructions given pursuant to this Section 2.21.  Any pre-
signed drafts held by the Issuing Lender 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

                                       26
<PAGE>
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 Issuing Lender to accept any such Acceptance Draft.)

          (c) Upon receipt of such notices from the Borrower, the Issuing Lender
shall promptly notify the Administrative Agent which shall promptly notify each
Lender of (i) its pro rata (based on its Revolving Credit Commitment) share of
such Acceptance Draft, (ii) the maturity date of such Acceptance Draft and (iii)
the discount rate and commission applicable to such Acceptance Draft.  The
Issuing Lender may decline to create any such Acceptance Draft if the Issuing
Lender is not then providing such financing to its middle market customers with
credit standings similar to the Borrower's.

          (d) 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 equaling or exceeding the amount of
such 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 any Acceptance
Draft.  The Borrower shall procure, prior to creation of any Acceptance Draft,
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 Issuing Lender, the
Administrative Agent and the Lenders that, as of the date of presentment, such
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 such Acceptance
Draft is outstanding.

          (e) The Borrower represents and warrants that, with respect to each
Acceptance Draft which the Borrower shall request the Issuing Lender to accept
and discount, (i) such Acceptance Draft will grow out of one or more
transactions involving the importation, exportation or domestic shipment of
goods, (ii) prior to any request that such Acceptance Draft be accepted and
discounted, the Borrower shall have entered into a contract or contracts
specifically providing for the transaction or transactions to which such
Acceptance Draft relates having an aggregate value not less than the face amount
of such Acceptance Draft, (iii) completion of the transaction or transactions to

                                       27
<PAGE>

which such Acceptance Draft relates will be scheduled to occur on or before the
maturity date of such Acceptance Draft, (iv) the maturity of such Acceptance
Draft will be consistent with the period usually and reasonably necessary to
finance transactions similar to the transaction or transactions to which such
Acceptance Draft relates, but in no case shall such period be longer than 120
days, (v) the proceeds of such Acceptance Draft shall be used solely to complete
the transaction or transactions to which such Acceptance Draft relates, and the
proceeds of such transaction or transactions shall be used to liquidate the
credit created by the acceptance and discounting of such Acceptance Draft, (vi)
the Borrower will not have outstanding any other financing of the transaction or
transactions to which such Acceptance Draft relates except under this Agreement,
(vii) the Borrower will be either (1) the importer or exporter of the goods, the
importation or exportation of which is being financed by such Acceptance Draft
or (2) the buyer or seller of the goods, the domestic shipment of which is being
financed by such Acceptance Draft, and (viii) such Acceptance Draft will be
eligible for discount under the Federal Reserve Act.

     2.22  Payment in Respect of Letters of Credit and Acceptances;
           --------------------------------------------------------
Reimbursement.  Upon the issuance of any Letter of Credit, the Issuing Lender
-------------
shall notify the Administrative Agent which shall notify each Lender of the
principal amount, the number, and the expiration date thereof and the amount of
such Lender's participation therein.  By the issuance of a Letter of Credit
hereunder and without further action on the part of the Issuing Lender, the
Administrative Agent or the Lenders, each Lender hereby accepts from the Issuing
Lender a participation (which participation shall be nonrecourse to the Issuing
Lender) in such Letter of Credit equal to such Lender's pro rata (based on its
Revolving Credit Commitment) share of such Letter of Credit, effective upon the
issuance of such Letter of Credit.  The Issuing Agent shall notify the
Administrative Agent which shall notify each Lender of the presentment to the
Issuing Lender 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 Issuing Agent shall notify the Administrative Agent
which shall:  (i) notify each Lender of the net proceeds thereof and the amount
of such Lender's participation therein (acquired pursuant to the terms hereof)
and (ii) credit the net proceeds thereof to the Borrower's account maintained
with the Administrative 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 Administrative Agent shall promptly notify the Borrower as to
the amount of the net funds so credited.  By acceptance of an Acceptance Draft
and without

                                       28
<PAGE>

further action on the part of the Issuing Lender, the Administrative
Agent or the Lenders, each Lender hereby accepts from the Issuing Lender a
participation (which participation shall be nonrecourse to the Issuing Lender)
in such Acceptance Draft equal to such Lender's pro rata (based on its Revolving
Credit Commitment) share of such Acceptance Draft, effective upon the issuance
of such Acceptance Draft.  Each Lender hereby absolutely and unconditionally
agrees to pay and discharge, and to indemnify and hold harmless the Issuing
Lender from liability in respect of, such Lender's pro rata share of the amount
of any drawing under a Letter of Credit and payment of any Acceptance Draft.
Each Lender acknowledges and agrees that its obligation to acquire
participations in each Letter of Credit issued by and each Acceptance Draft
accepted by the Issuing Lender and its obligation to make the payments specified
herein, and the right of the Issuing Lender 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 Issuing Lender shall review, on behalf of the Lenders, each
draft presented under a Letter of Credit and shall notify each Lender of any
such presentment.  Promptly after it shall have ascertained that any draft
presented under any Letter of Credit appears on its face to be in substantial
conformity with the terms and conditions of such Letter of Credit, the Issuing
Lender shall give notice to the Administrative Agent which shall give telephonic
or facsimile notice to the Lenders and the Borrower of the receipt and amount of
such draft and the date on which payment thereon will be made.  The Borrower
shall pay to the Issuing Lender 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 and shall pay to the Issuing Lender the face amount of any Acceptance Draft
on the maturity date thereof.  If the Borrower has not so discharged such
payment obligations and the Issuing Lender is unable to recover the required
amount by debiting the Borrower's account, the Issuing Lender shall give the
Administrative Agent notice which shall give each Lender notice of any amount
that remains unpaid, and each Lender shall promptly, but in any event within two
hours of the receipt of such notice, pay the amounts required to the Issuing
Lender in immediately available funds, and, with respect to Letters of Credit,
the Issuing Lender, not later than 3:00 p.m. (Philadelphia time) on such day,
shall make the appropriate payment to the applicable beneficiary.  If the
Lenders shall pay to the Issuing Lender the amount of any draft presented under
a Letter of Credit or make any such payment upon the maturity of an Acceptance
Draft, then the Issuing Lender, on behalf of the Lenders, shall charge the
general deposit account of the Borrower with the Issuing Lender for the amount
thereof, together with the Issuing Lender's customary overdraft or similar fee
in the event

                                       29
<PAGE>

the funds available in such account shall not be sufficient to reimburse the
Lenders for such payment. If the Lenders have not been paid with respect to any
drawing or any Acceptance Draft as provided above, the Borrower shall pay to the
Issuing Lender, for the account of the Lenders, the amount of such 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
Involuntary Rate, payable on demand. The obligations of the Borrower under this
Section 2.22 to pay the Issuing Lender, the Lenders and the Administrative 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 any Letter of Credit or the holder of any Acceptance Draft, the Issuing
Lender, the Administrative Agent or any Lender (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 Issuing Lender, the Administrative Agent or any Lender) or any other
Person in connection with this Agreement or any other transaction;

          (c) any draft or other document presented under or in connection with
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;

          (d) payment by the Issuing Lender 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;

          (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; or

          (h) any other circumstance or event whatsoever, whether or not similar
to any of the foregoing.

                                       30
<PAGE>

          Neither the Issuing Lender, the Administrative Agent nor a Lender
shall have any liability or responsibility by reason of or in connection with
the issuance or transfer of any Letter of Credit or Acceptance Draft or any
payment or failure to make payment thereunder (irrespective of any of the
circumstances referred to above), or any error, omission, interruption, loss or
delay in transmission or delivery of any draft, notice or other communication
under or relating to any Letter of Credit (including any document required to
make a drawing thereunder), any error in interpretation of technical terms or
any consequence arising from causes beyond the control of the Issuing Lender,
the Administrative Agent or a Lender, provided that the foregoing shall not be
construed to excuse the Issuing Lender, the Administrative Agent or a Lender
from liability to the Borrower to the extent of damages suffered by the Borrower
that are caused by the Issuing Lender=s, the Administrative Agent's or such
Lender's gross negligence or willful misconduct.  It is understood that in
making any payment under any Letter of Credit (x) the Issuing Lender=s exclusive
reliance on the documents presented to it under such Letter of Credit 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,
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
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 proves to be forged or invalid or
any statement 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 with the terms thereof shall, in each
case, not be deemed willful misconduct or gross negligence of the Issuing
Lender.

     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 Issuing Lender, 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
Bank or if for any other reason any Acceptance Draft is deemed by the Issuing
Lender not eligible for discount, the Borrower will, upon receipt of written
notice from the Issuing Lender, forthwith pay to the Issuing Lender any
additional cost or costs, as determined by the Issuing Lender, incurred by the
Issuing Lender (including, without limitation, any costs resulting from a higher
discount rate upon disposition of such Acceptance Draft by the Issuing Lender,
any funding costs resulting from a higher discount rate upon disposition of such
Acceptance Draft by the Issuing Lender, reserve requirements or additional
premium liability to the

                                       31

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 Administrative Agent and the Lenders to enter into
this Agreement and to make the Loans and to issue Letters of Credit and to
create Acceptance Drafts herein provided for, the Borrower hereby covenants,
represents and warrants to the Administrative Agent and the Lenders 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 29, 2000 audited by Lazar Levine &
Company, LLC, CPAs and the interim consolidated balance sheet and related
consolidated statements of income, retained earnings and cash flows as of May
31, 2000 have heretofore been furnished to the Lenders, and fairly present the
financial condition of the Borrower and its Subsidiaries as at such dates, and
the results of their operations 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 the year
end adjustments.  Neither the Borrower nor any of 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 May 31, 2000 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.  Each of the
          ------------------------------------------------------
Borrower and each of its Subsidiaries (i) is duly organized, validly existing

(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 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

                                       32
<PAGE>

whole, and would not materially adversely affect the ability of the Borrower or
a Subsidiary to perform its obligations under the Loan Documents.

     3.4  Corporate Power; Authorization; Enforceable Obligations.  The
          -------------------------------------------------------
Borrower and each of its Subsidiaries has the corporate power and authority and
the legal right to execute, deliver and perform its obligations under the Loan
Documents and, in the case of the Borrower, to borrow and obtain other
extensions of credit hereunder.  The Borrower has taken all necessary corporate
action to authorize the borrowings and other extensions of credit 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 and
other extensions of credit 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 and other extensions of credit 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.

     3.6  No Material Litigation.  No litigation, investigation or proceeding
          ----------------------
of or before any arbitrator or Governmental Authority is pending by or against
the Borrower or any Subsidiary or any of its respective properties or revenues

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.

                                       33
<PAGE>

     3.7  No Default.  Neither the Borrower nor any of its Subsidiaries is 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 as now and from time to time
hereafter in effect.  No part of the proceeds of any Loans hereunder, and no
Letter of Credit or Acceptance Draft, 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 the
Board.

     3.10 Environmental Regulation. (a)  The Borrower has no knowledge of
          ------------------------
receipt of any past, pending or threatened:

             (i) claims, complaints, notices or requests for information with
respect to any alleged violation of 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 financial or business conditions of the Borrower
and its Subsidiaries taken as a whole; or

             (ii) complaints, notices or inquiries to the Borrower or any
Subsidiary of the Borrower 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 financial or business
conditions of the Borrower and its Subsidiaries taken as a whole;

          (b) No property now or previously owned or leased by the Borrower or
any Subsidiary of the Borrower is listed or proposed for listing on the National
Priorities List pursuant to

                                       34
<PAGE>

CERCLA, on CERCLIS or on any similar state list of sites requiring investigation
or clean-up; and

           (c) Neither the Borrower nor any Subsidiary of the Borrower has
directly transported or directly arranged for the transportation of any
Hazardous Material to any location which is listed or proposed for listing on
the National Priorities List pursuant to CERCLA, on CERCLIS or on any similar
state list or which is the subject of federal, state or local enforcement
actions or other investigations which may lead to material claims against the
Borrower for any remedial work, damage to natural resources or personal injury,
including claims under CERCLA.

     3.11  Title to Properties.  Each of the Borrower and its Subsidiaries has
           -------------------
valid leases of or good and marketable title to its respective properties and
assets, including the properties and assets reflected in the balance sheets
described in Section 3.1 hereof.  Such properties and assets are not subject to
any Lien, except as reflected in such balance sheets and except to the extent
otherwise permitted by Section 7.2 hereof.

     3.12  Taxes.  The Borrower and its Subsidiaries have filed all Federal,
           -----
state and other tax returns which to the knowledge of the Borrower and its

payable on said returns or on any assessments made against them or any of their
respective properties except such taxes, if any, as are being contested in good
faith and by proper proceedings and as to which adequate reserves have been
maintained in conformity with GAAP.

     3.13  ERISA.  Based upon ERISA and the regulations and published
           -----
interpretations thereunder, each of the Borrower, its Subsidiaries and each
ERISA Affiliate is in compliance in all material respects with all applicable
provisions, if any, of ERISA.  Neither a Reportable Event nor a Prohibited
Transaction has occurred and is continuing with respect to any Plan; no notice
of intent to terminate a Plan has been filed nor has any Plan been terminated;
no circumstances exist which constitute grounds under Section 4042 of ERISA
entitling the PBGC to institute proceedings to terminate, or appoint a trustee
to administer, a Plan, nor has the PBGC instituted such proceedings;  each of
the Borrower, its Subsidiaries and each ERISA Affiliate has met its minimum
funding 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 such 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 such Plan under Title IV of
ERISA, and neither the

                                       35
<PAGE>

Borrower, its Subsidiaries nor an ERISA Affiliate has incurred any liability to
the PBGC under ERISA.

     3.14  Operation of Business.  The Borrower and its Subsidiaries possess
           ---------------------
all licenses, permits, franchises, patents, copyrights, trademarks, and trade
names, or rights thereto, necessary to conduct their respective businesses
substantially as now conducted and as presently proposed to be conducted, and
neither the Borrower nor any Subsidiary is in material violation of any valid
rights of others with respect to any of the foregoing except where the failure
to obtain licenses or permits does not individually or in the aggregate
materially and adversely impair the ability of a Borrower or any of its
Subsidiaries to operate its business or perform its obligations under a Loan
Document.

                       SECTION 4.  CONDITIONS PRECEDENT

                                       50
<PAGE>

the Administrative Agent with the written consent of the Required Lenders may,
and upon the written request of the Required Lenders shall, by notice of default

shall immediately terminate; (ii) the Administrative Agent with the written
consent of the Required Lenders may, and upon the written request of the
Required Lenders shall, by notice of default to the Borrower, declare the entire

however, that upon the happening of an event specified in subsection (f) of this

                       SECTION 9.  ADMINISTRATIVE AGENT
                                   --------------------

     In order to expedite the transactions contemplated by this Agreement,
Mellon Bank, N.A. is hereby appointed to act as Administrative Agent on behalf
of the Lenders.  Each of the Lenders and each subsequent holder of any Note or
issuer of any Letter of Credit, irrevocably authorizes the Administrative Agent
to take such action on its behalf and to exercise such powers hereunder and
under the other Loan Documents as are specifically delegated to or required of
the Administrative Agent by the terms hereof and the terms thereof together with
such powers as are reasonably incidental thereto.  Neither the Administrative
Agent nor any of its directors, officers, employees or Administrative 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 other Loan Documents or in connection
herewith or therewith (a) at the request or with the approval of the Required
Lenders (or, if otherwise specifically required hereunder or thereunder, the
consent of the Lenders) or (b) in the absence of its or their own gross
negligence or willful misconduct.

     The Administrative Agent is hereby expressly authorized on behalf of the
Lenders, without hereby limiting any implied authority, and the Administrative
Agent hereby agrees, (a) to receive on behalf of each of the Lenders any payment
of principal of or interest on the Notes outstanding hereunder and all other

                                       51
<PAGE>

amounts accrued hereunder paid to the Administrative Agent, and promptly to
distribute to each Lender its proper share of all payments so received, (b) to
distribute to each Lender copies of all notices, agreements and other material
as provided for in this Agreement or in the other Loan Documents as received by
the Administrative Agent and (c) to take all actions with respect to this
Agreement and the other Loan Documents as are specifically delegated to the
Administrative Agent.

     In the event that (a) the Borrower fails to pay when due the principal of
or interest on any Note, any amount payable under any Letter of Credit or
Acceptance Draft, or any fee payable hereunder or (b) the Administrative Agent
receives written notice of the occurrence of a Default or an Event of Default,
the Administrative Agent within a reasonable time shall give written notice
thereof to the Lenders; 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
Required Lenders or all Lenders, as applicable hereunder; provided, however,
that, unless and until the Administrative Agent shall have received such
directions, the Administrative 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 Lenders.

     The Administrative Agent shall not be responsible in any manner to any of
the Lenders for the effectiveness, enforceability, perfection, value,
genuineness, validity or due execution of this Agreement, the 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, 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 Administrative 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 Lender which is the Administrative 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
Administrative Agent of the Lenders hereunder.

                                       52
<PAGE>

     The Administrative Agent shall promptly give notice to the Lenders 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
Lender.

     Neither the Administrative 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 Lender of any of its
obligations hereunder or to any Lender on account of the failure of or delay in
performance or breach by any other Lender or the Borrower of any of their
respective obligations hereunder or in connection herewith.

     The Administrative 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 Administrative 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 Administrative Agent and the Borrower may deem and treat the payee or
most recent assignee pursuant to Section 10.3 hereof, as applicable, of any Note
as the holder thereof until written notice of transfer shall have been delivered
as provided in Section 10.3 hereof by such payee to the Administrative Agent and
the Borrower.

     With respect to the Loans made hereunder, the Notes issued to it and any
other extension of credit applicable to it, the Lender which is the
Administrative Agent in its individual capacity as the Issuing Lender, Swing
Lender or Lender and not as an Administrative Agent shall have the same rights,
powers and duties hereunder and under any other agreement executed in connection
herewith as any other Lender and may exercise the same as though it were not the
Administrative Agent, and the Lender which is the Administrative 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 Administrative Agent.

     Each Lender agrees (i) to reimburse the Administrative Agent in the amount
of such Lender's pro rata share (based on its Revolving Credit Commitment
hereunder) of any reasonable out-of-pocket expenses incurred for the benefit of
the Lenders by the Administrative Agent, including reasonable fees and
disbursements of counsel to the Administrative Agent and compensation of agents
and employees paid for services rendered on behalf of the Lenders, not
reimbursed by the Borrower pursuant to Section 10.4 hereof and (ii) to indemnify
and hold harmless the Administrative Agent and any of its directors, officers,
employees or agents, on demand, in

                                       53
<PAGE>

the amount of its pro rata share (based on its Revolving Credit Commitment
hereunder), 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 Administrative 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 pursuant to Section 10.4 hereof; provided, however, that no Lender
shall be liable to the Administrative 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 Administrative Agent or any of its directors, officers,
employees or agents.

     Each Lender acknowledges that it has, independently and without reliance
upon the Administrative Agent or any other Lender 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
Lender is a party.  Each Lender also acknowledges that it will, independently
and without reliance upon the Administrative Agent or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own 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 Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower.  Upon any such resignation, the Lenders
shall have the right to appoint a successor Administrative Agent.  If no
successor Administrative Agent shall have been so appointed by such Lenders and
shall have accepted such appointment within thirty (30) days after the retiring
Administrative Agent gives notice of its resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent which shall be a Lender 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
Administrative Agent hereunder by a successor, such successor shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent and the retiring Administrative Agent shall
be discharged from its duties and obligations hereunder and under each of the
other Loan Documents.  After any Administrative 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
Administrative Agent.

                                       54
<PAGE>

     The Lenders hereby acknowledge that the Administrative Agent shall be under
no duty to take any discretionary action permitted to be taken by the
Administrative 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 Lenders.

effect as long as the principal of or any accrued interest on the Notes or any

     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 Administrative Agent or the
Lenders, that are contained in this Agreement shall bind and inure to the
benefit of such Persons and their respective successors and assigns.  Without
limiting the generality of the foregoing, the Borrower specifically confirms
that the Administrative Agent and each Lender may at any time and from time to
time assign or pledge or otherwise grant a security interest in any Loan or any
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

transfer without such consent shall be null and void.

          (b) Each Lender, 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 Loans owing to it and
undrawn Letters of Credit and Acceptance Drafts and the Notes held by it);
provided, however, that (i) such Lender's obligations under this Agreement
(including, without limitation, its Revolving Credit Commitment) shall remain
unchanged, (ii) such Lender 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 2.7 and 2.10 hereof (except to the extent that
application of such Section 2.10 to such banks and other entities would cause
the Borrower to make duplicate payments thereunder), and (iv) the Borrower, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.

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

                                       56
<PAGE>

Affiliates or to another Lender no such consent of the Administrative Agent or
the Borrower 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 Loans and undrawn Letters of Credit and Acceptance Drafts at
the time owing to it and the Notes 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 Lender's rights and obligations under this Agreement, which shall
include the same percentage interest in the Loans, Letters of Credit, Acceptance
Drafts and Notes, (ii) the amount of the Revolving Credit Commitment of the
assigning Lender 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 Administrative Agent) shall be in a minimum principal amount of
$5,000,000 and (iii) the parties to each such assignment shall execute and
deliver to the Administrative Agent, for its acceptance and recording in the
Register (as defined below), an assignment and acceptance in form and substance
acceptable to the Administrative Agent (an "Assignment and Acceptance"),
together with any Note subject to such assignment and a processing and
recordation fee of $2,500.00 payable by the assigning Lender. Upon such
execution, delivery, acceptance and recording and after receipt of the written
consent of the Administrative 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 Lender hereunder and under the other Loan
Documents and (y) the Lender 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
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto and thereto except in respect of Sections 2.10 and 10.4 hereof
for the period prior to the effective date thereof).

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

sufficiency or value of this Agreement, the other Loan Documents or any other
instrument or document furnished pursuant hereto or thereto; (ii) such Lender
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 Administrative Agent, such Lender or any other Lender
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and authorizes the
Administrative Agent to take such action as the Administrative Agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Administrative 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 Lender.

          (e) The Administrative 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 Lenders and
the Revolving Credit Commitment of, and principal amount of the Loans and other
extensions of credit owing to, each Lender 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 Administrative Agent and the Lenders may treat
each Person whose name is so recorded in the Register as a Lender hereunder for
all purposes of this Agreement.  The Register shall be available for inspection
by the Borrower or any Lender 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 Lender and an assignee together with any Note subject to such
assignment and the written consent to such assignment, the Administrative 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
Lenders and the Borrower.  Within five (5) Business Days after receipt of such
notice, the Borrower, at its own expense, shall

                                       58

execute and deliver to the Administrative Agent in exchange for each surrendered
Note or Notes a new 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 Lender has retained any Revolving Credit
Commitment hereunder, a new Note to the order of the assigning Lender in an
amount equal to the Revolving Credit Commitment retained by it hereunder. Such
new Note shall be in an aggregate principal amount equal to the aggregate
principal amount of such surrendered 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 Lender may, in
connection with any assignment or participation or proposed assignment or
participation pursuant to this Section 10.3, disclose to the assignee or
participant or proposed assignee or participant, any information relating to the
Borrower, any Guarantor or any Subsidiary of any thereof furnished to such
Lender by or on behalf of the Borrower, such Guarantor or such Subsidiary 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, any Guarantor or any Subsidiary of any
thereof received from such Lender.

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

out-of-pocket expenses incurred by the Administrative Agent in connection with
the preparation of this Agreement, the Notes and the other Loan Documents or
with any amendments, modifications or waivers of the provisions hereof or
thereof or incurred by the Administrative Agent or any of the Lenders 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 Notes or Letters of Credit or Acceptance Drafts issued
hereunder or the use of proceeds therefrom, 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 Administrative Agent and, in connection with such enforcement or
protection, the reasonable fees and disbursements of counsel for the Lenders.
The Borrower further indemnifies the Lenders 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 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 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 Administrative Agent or any Lender.  All amounts due under this
Section 10.4 shall be payable on written demand therefor.

     10.5  Applicable Law.  THIS AGREEMENT AND THE 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, each Lender 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 or final) at any
time held and other indebtedness at any time owing by such Lender 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 Notes held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement or the Notes and although such
obligations may be unmatured.  Each Lender agrees to notify promptly the
Administrative Agent and the Borrower and any applicable Guarantor after any
such setoff and application made by such Lender, but the failure to give such
notice shall not affect the validity of such setoff and application.  The rights
of each Lender under this Section are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which may be available
to such Lender.

     10.7  Payments on Business Days.  Should the principal of or interest on
           -------------------------
the 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 and fees payable
hereunder.

     10.8  Waivers; Amendments.  (a) No failure or delay of any Lender 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 Lenders 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 Notes nor

                                       60
<PAGE>

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 Notes shall be
bound by any amendment, modification, waiver or consent authorized as provided
herein, whether or not such 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 and the Required Lenders or by the Borrower and the
Administrative Agent with the consent of the Required Lenders; provided that no
                                                               --------
such agreement shall (i) increase the Revolving Credit Commitment of any Lender
without the written consent of such Lender, (ii) reduce the principal amount of
any Loan or reduce the rate of interest thereon, or reduce any fees payable
hereunder, or reduce any payment by the Borrower hereunder in respect of any
Letter of Credit or Acceptance Draft without the written consent of each Lender
affected thereby, (iii) postpone the scheduled date of payment of the principal
amount of any Loan or any interest thereon, or any fees payable hereunder, or
any payment by the Borrower hereunder in respect of any Letter of Credit or
Acceptance Draft or reduce the amount of, waive or excuse any such payment, or
postpone the scheduled date of expiration of any Revolving Credit Commitment,
without the written consent of each Lender affected thereby, (iv) change Section
2.13 or 2.14 hereof in a manner that would alter the pro rata sharing of
payments required thereby, without the written consent of each Lender, (v)
change any of the provisions of this Section or the definition of "Required
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder without the written consent of each
Lender, or (vi) release any Guarantee without the written consent of each
Lender; provided further that no such agreement shall amend, modify or otherwise
        ----------------
affect the rights or duties of the Administrative Agent or the Swing Lender
hereunder without the prior written consent of the Administrative Agent or the
Swing Lender, as the case may be.

     10.9 Severability.  In the event any one or more of the provisions
          ------------
contained in this Agreement or in the 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

                                       61
<PAGE>

the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

            -------------------------------------------
the Notes and the other Loan Documents constitute the entire contract between
the parties hereto relative to the subject matter hereof and thereof.  Any
previous agreement among the parties hereto with respect to the transactions

Notes or the other Loan Documents, nothing in this Agreement, the Notes or the
other Loan Documents is intended to confer upon any party, other than 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

right it may have to claim or recover in any litigation referred to in paragraph
(b) of this Section 10.10 any special, exemplary or punitive damages.

            (d) Each party hereto (i) certifies that no representative, agent or
attorney of any Lender has represented, expressly or otherwise, that such Lender
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
Notes or the other Loan Documents, as applicable, by, among other things, the
mutual waivers and certifications herein.

     10.11  Confidentiality.  The Administrative Agent and the Lenders 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 Administrative Agent or any Lender (the
"Information").  Notwithstanding the foregoing, the Administrative Agent and
each Lender shall be permitted to disclose Information (i) to such of its
officers, directors, employees, agents, attorneys and representatives as need to
know such Information in connection with its participation in any of the
contemplated 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

Administrative Agent or such Lender on a non-confidential basis prior to its
disclosure to the Administrative Agent or such Lender 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; (vi)
pursuant to Section 10.3(g) hereof; or (vii) in connection with any litigation
to which the Administrative Agent or any Lender is a party.

            --------------------------
with respect to this Agreement or the Notes or any other Loan Document may be
brought in the courts of the State of New York or of the United States of
America for the Southern District of New York, and, by execution and delivery of

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,

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, postage prepaid, to each such person, as the case may be, at its
address set forth in Section 10.1 hereof.

            (d) Nothing herein shall affect the right of the Administrative
Agent or any Lender to serve process in any other manner permitted by law or to
commence legal proceedings or otherwise proceed against the Borrower or any
Guarantor in any other jurisdiction.
