                  Receivables Advance Rate and the Inventory Advance Rate shall
                  be referred to, collectively, as the "Advance Rates"), minus
                                                                         -----

                      (iv)    such reserves as Agent may, in a commercially
                  reasonable manner, reasonably deem proper and necessary.

                  The amount derived from the sum of Sections 2.1(a)(y)(i),
         (ii), (iii) and (iv) at any time and from time to time shall be
         referred to as the "Formula Amount". The Revolving Advances shall be
         evidenced by one or more secured promissory notes (collectively, the
         "Revolving Credit Note") substantially in the form attached hereto as
         Exhibit 2.1(a).

                  (b) Discretionary Rights. The Advance Rates may be increased
                      --------------------
         by the Agent, with the consent of the Required Lenders, or decreased by
         the Agent, with the consent of the Required Lenders, at any time and
         from time to time in the exercise of its reasonable discretion.
         Borrowers consent to any such increases or decreases and acknowledge
         that decreasing the Advance Rates or increasing the reserves may limit
         or restrict Advances requested by any Borrower.

         2.2.     PROCEDURE FOR BORROWING.
                  -----------------------

         (a) Borrowing Agent on behalf of any Borrower may notify Agent prior to
11:00 a.m. on a Business Day of a Borrower's request to incur by delivery of a
Notice of Borrowing, substantially in the form of Exhibit 2.2(a) attached
                                                  --------------
hereto, on that day, a Revolving Advance hereunder. Should any amount required
to be paid as interest hereunder, or as fees or other charges under this
Agreement or any other agreement with Agent or any Lender, or with respect to
any other Obligation, become due, same shall be deemed a request for a Revolving
Advance as of the date such payment is due, in the amount required to pay in
full such interest, fee, charge or Obligation under this Agreement or any other
agreement with Agent or any Lender, and such request shall be irrevocable. Any
request for a Revolving Advance shall be deemed reduced automatically and
without notice so as not to be in excess of, after giving effect to the
requested Revolving Advance, an amount which would cause the aggregate amount of
all Advances outstanding to be greater than the Borrowing Base.

         (b) Notwithstanding the provisions of (a) above, in the event any
Borrower desires to obtain a Eurodollar Rate Loan, Borrowing Agent shall give
Agent at least three (3) Business Days' prior written notice, specifying (i) the
date of the proposed borrowing (which shall be a Business Day), (ii) the type of
borrowing and the amount on the date of such Advance to be borrowed, which
amount shall be in a minimum amount of $1,000,000.00 and in integral multiples
of $500,000.00 thereafter, and (iii) the duration of the first Interest Period
therefor. Interest Periods for Eurodollar Rate Loans shall be for one, two,
three or six months; provided, if an Interest Period would end on a day that is
                     --------
not a Business Day, it shall end on the next succeeding Business Day unless such
day falls in the next succeeding calendar month in which case the Interest
Period shall end on the next preceding Business Day. No Eurodollar Rate Loan
shall be made available to Borrower during the continuance of a Default or an
Event of Default. There shall not be outstanding more than seven (7) Eurodollar
Rate Loans, in the aggregate.

                                      19
<PAGE>

         (c) Each Interest Period of a Eurodollar Rate Loan shall commence on
the date such Eurodollar Rate Loan is made and shall end on such date as a
Borrower may elect as set forth in (b)(iii) above provided that:

             (iv) no Interest Period shall end after the last day of the Term;
         and

             (v)  any Interest Period which begins on a day for which there is
         no numerically corresponding day in the calendar month during which
         such Interest Period is to end, shall (subject to subsection (b) above)
         end on the last day of such calendar month.

         Borrowing Agent shall elect the initial Interest Period applicable to a
Eurodollar Rate Loan by its notice of borrowing given to Agent pursuant to
Section 2.2(b) or by its notice of conversion given to Agent pursuant to Section
2.2(d), as the case may be. Borrowing Agent shall elect the duration of each
succeeding Interest Period by giving irrevocable written notice to Agent of such
duration not less than three (3) Business Days prior to the last day of the then
current Interest Period applicable to such Eurodollar Rate Loan. If Agent does
not receive timely notice of the Interest Period elected by Borrowing Agent,
Borrowers shall be deemed to have elected to convert to a Domestic Rate Loan
subject to Section 2.2(d) hereinbelow.

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

         (e) Borrowers may prepay the Revolving Advances in accordance with the
provisions of Section 13.1 with accrued interest on the principal being prepaid
to the date of such repayment. In the event that any prepayment of a Eurodollar
Rate Loan is required or permitted on a date other than the last Business Day of
the then current Interest Period with respect thereto Borrowers shall indemnify
Agent and Lenders therefor in accordance with Section 2.2(f) hereof.

         (f) Each Borrower shall indemnify Agent and Lenders and hold Agent and
Lenders harmless from and against any and all losses or expenses that Agent and
any Lender may sustain or incur as a consequence of any prepayment or any
default by any Borrower in the payment of the principal of or interest on any
Eurodollar Rate Loan or failure by any Borrower to complete a borrowing of, a
prepayment of or conversion of or to a Eurodollar Rate Loan after notice thereof
has been given, including but not limited to, any interest payable by Agent or
any Lender to lenders of funds obtained by it in order to make or maintain its
Eurodollar Rate Loans hereunder.

                                      20
<PAGE>

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

         (h) Anything in Section 2.2(b) to the contrary notwithstanding, any
Borrower may obtain a Eurodollar Rate Loan upon at least three (3) Business
Days' prior written notice for an Interest Period of one month with interest on
such Eurodollar Rate Loans to be charged at the Average Monthly Eurodollar Rate.
Borrowing Agent shall specifically provide in the prior written notice that
interest is to be charged at the Average Monthly Eurodollar Rate; otherwise,
interest shall be charged at the Eurodollar Rate for Eurodollar Rate Loans
having an Interest Period of one month.

         2.3.     DISBURSEMENT OF ADVANCE PROCEEDS.
                  --------------------------------

         All Revolving Advances shall be disbursed from whichever office or
other place Agent may designate from time to time and, together with any and all
other Obligations of Borrowers to Agent or any of the Lenders, shall be charged
to the applicable Borrower's account on Agent's books. During the Term,
Borrowers may use the Revolving Advances by borrowing, prepaying and
reborrowing, all in accordance with the terms and conditions hereof. The
proceeds of each Revolving Advance requested on behalf of any Borrower or deemed
to have been requested by such Borrower under Section 2.2(a) hereof shall, with
respect to requested Revolving Advances to the extent the Lenders make such
Revolving Advances, be made available to such Borrower on the day so requested
by way of credit to such Borrower's operating account at the Bank, or such other
bank as Borrowing Agent may designate following notification to Agent, in
federal funds or other immediately available funds or, with respect to Revolving
Advances deemed to have been requested, be disbursed to Agent to be applied to
the outstanding Obligations giving rise to such deemed request.

         2.5.     MAXIMUM ADVANCES.
                  ----------------

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

         2.6.     REPAYMENT OF ADVANCES.
                  ---------------------

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

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

         (c)      All payments of principal, interest and other amounts payable
hereunder, or under any of the related agreements shall be made to Agent at the
Payment Office not later than 1:00 P.M. New York Time on the due date therefor
in lawful money of the United States of America in federal funds or other funds
immediately available to Agent. Agent shall have the right to effectuate payment
on any and all Obligations due and owing hereunder by charging the applicable
Borrower's account or by making Advances as provided in Section 2.2 hereof.

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

         2.7.     REPAYMENT OF EXCESS ADVANCES.
                  ----------------------------

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

         2.8.     STATEMENT OF ACCOUNT.
                  --------------------

         Agent shall maintain, in accordance with its customary procedures, a
loan account in the name of each Borrower in which shall be recorded the date
and amount of each Advance made

                                      22
<PAGE>

by Lenders and the date and amount of each payment in respect thereof; provided,
                                                                       --------
however, the failure by Agent to record the date and amount of any Advance shall
-------
not adversely affect Agent or any Lender. Each month, Agent shall send to
Borrowing Agent a statement showing the accounting for the Advances made,
payments made or credited in respect thereof, and other transactions between
Lenders and each Borrower, during such month. The monthly statements shall be
deemed correct and binding upon Borrowers in the absence of manifest error and
shall constitute an account stated between Lenders and Borrowers unless Agent
receives a written statement of a Borrower's specific exceptions thereto within
thirty (30) days after such statement is received by Borrowing Agent. The
records of Agent with respect to the loan account shall be prima facie evidence
                                                           ----- -----
of the amounts of Advances and other charges thereto and of payments applicable
thereto, absent manifest error.

         2.9.     LETTERS OF CREDIT.
                  -----------------

         (a)      Subject to the terms and conditions hereof, (i) Agent shall
issue or cause the issuance of standby and documentary letters of credit for the
Borrowers ("Letters of Credit") provided, however, that Agent will not be
                                --------  -------
required to issue or cause to be issued Letters of Credit to the extent that the
face amount of such Letters of Credit plus the Revolving Advances outstanding
                                      ----
(with the requested Letter of Credit being deemed to be outstanding for purposes
of this calculation) would exceed the Borrowing Base.

         (b)      The maximum amount of outstanding (i) Letters of Credit that
are standby letters of credit hereunder shall not exceed $5,000,000 in the
aggregate at any time, and (ii) Letters of Credit that are documentary letters
of credit hereunder shall not exceed $1,000,000 in the aggregate at any time.
Letters of Credit issued hereunder shall not have an original expiry date more
than one year from the date of issuance or extension, nor an expiry date,
whether as originally issued or by extension, extending beyond the end of the
Term.

         (c)      All disbursements or payments related to Letters of Credit
         shall be deemed to be Revolving Advances and shall bear interest at
         the Revolving Interest Rate for Domestic Rate Loans (unless and until
         converted to a Eurodollar Rate Loan); and to the extent not drawn upon,
         Letters of Credit that have not been drawn upon shall not bear
         interest. Letters of Credit shall be subject to the terms and
         conditions set forth in the Application and Agreement for Letter of
         Credit attached hereto as Exhibit 2.9.
                                   -----------

         2.10.    ISSUANCE OF LETTERS OF CREDIT.
                  -----------------------------

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

                                      23
<PAGE>

applicable agreement, any letter of credit and the disposition of documents,
disposition of any unutilized funds, and to agree with Agent upon any amendment,
extension or renewal of any Letter of Credit.

         (b)      Each Letter of Credit shall, among other things, (i) provide
for the payment of sight drafts when presented for honor thereunder in
accordance with the terms thereof and when accompanied by the documents
described therein and (ii) have an expiry date not later than twelve (12) months
after such Letter of Credit's date of issuance and in no event later than the
last day of the Term. Each Letter of Credit Application and each Letter of
Credit shall be subject to the Uniform Customs and Practice for Documentary
Credits (1993 Revision), International Chamber of Commerce Publication No. 500)
and any amendments or revision thereof and, to the extent not inconsistent
therewith, the laws of the Commonwealth of Pennsylvania.

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

         (d)      Agent shall have absolute discretion whether to accept any
draft. Without in any way limiting Agent's absolute discretion whether to accept
any draft, Borrowing Agent will not present for acceptance any draft, and Agent
will generally not accept any drafts (i) that arise out of transactions
involving the sale of goods by any Borrower not in the ordinary course of its
business, (ii) that involve a sale to an Affiliate of any Borrower and (iii)
that involve any purchase for which Agent has not received all related
documents, instruments and forms requested by Agent.

         2.11.    REQUIREMENTS FOR ISSUANCE OF LETTERS OF CREDIT.
                  ----------------------------------------------

         (a)      In connection with the issuance of any Letter of Credit,
(subject to the limitations of the Cross-Guaranty set forth in Section 17.1
hereof) Borrowers shall indemnify, save and hold Agent and each Lender harmless
from any loss, cost, expense or liability, including, without limitation,
payments made by Agent and any Lender, and expenses and reasonable attorneys'
fees incurred by Agent or any Lender arising out of, or in connection with, any
Letter of Credit to be issued or created for a Borrower. Borrowers shall be
bound by Agent's or any issuing or accepting bank's regulations and good faith
interpretations of any Letter of Credit issued or created for its account,
although this interpretation may be different from its own, and, neither Agent
nor any Lender, the bank which opened the Letter of Credit, nor any of its
correspondents shall be liable for any error, negligence, or mistakes, whether
of omission or commission, in following Borrowing Agent's or any Borrower's
instructions or those contained in any Letter of Credit or of any modifications,
amendments or supplements thereto or in issuing or paying any Letter of Credit,
except for Agent's or any Lender's or such correspondents' willful misconduct or
gross (not mere) negligence.

         (b)      Borrowing Agent shall authorize and direct any bank which
issues a Letter of Credit to name the applicable Borrower as the "Account Party"
therein and to deliver to Agent all instruments, documents, and other writings
and property received by the bank pursuant to the Letter of Credit and to accept
and rely upon Agent's instructions and agreements with respect to

                                      24
<PAGE>

all matters arising in connection with the Letter of Credit, the application
therefor or any acceptance therefor.

         (c)      In connection with all Letters of Credit issued or caused to
be issued by Agent under this Agreement, each Borrower hereby appoints Agent, or
its designee, as its attorney, with full power and authority, (i) to sign and/or
endorse such Borrower's name upon any warehouse or other receipts, letter of
credit applications and acceptances; (ii) to sign such Borrower's name on bills
of lading; (iii) to clear Inventory through the United States of America Customs
Department ("Customs") in the name of such Borrower or Agent or Agent's
designee, and to sign and deliver to Customs officials powers of attorney in the
name of such Borrower for such purpose; and (iv) to complete in such Borrower's
name or Agent's, or in the name of Agent's designee, any order, sale or
transaction, obtain the necessary documents in connection therewith, and collect
the proceeds thereof. Neither Agent nor its attorneys will be liable for any
acts or omissions nor for any error of judgment or mistakes of fact or law,
except for Agent's or its attorney's willful misconduct or gross (not mere)
negligence. This power, being coupled with an interest, is irrevocable as long
as any Letters of Credit remain outstanding.

         (d)      Each Lender shall to the extent of the percentage amount equal
to the product of such Lender's Commitment Percentage times the aggregate amount
of all disbursements made with respect to the Letters of Credit be deemed to
have irrevocably purchased an undivided participation in each such unreimbursed
reimbursement obligation. In the event that at the time a disbursement is made
the unpaid balance of Revolving Advances exceeds or would exceed, with the
making of such disbursement, the Borrowing Base minus the undrawn or
                                                -----
unreimbursed amount of outstanding Letters of Credit issued on behalf of the
Borrowers, and such disbursement is not reimbursed by Borrowers within two (2)
Business Days, Agent shall promptly notify each Lender and upon Agent's demand
each Lender shall pay to Agent such Lender's proportionate share of such
unreimbursed disbursement together with such Lender's proportionate share of
Agent's unreimbursed costs and expenses relating to such unreimbursed
disbursement. Upon receipt by Agent of a repayment from Borrowers of any amount
disbursed by Agent for which Agent had already been reimbursed by the Lenders,
Agent shall deliver to each of the Lenders that Lender's pro rata share of such
repayment. Each Lender's participation commitment shall continue until the last
to occur of any of the following events: (A) Agent ceases to be obligated to
issue Letters of Credit hereunder; (B) no Letter of Credit issued hereunder
remains outstanding and uncancelled or (C) all Persons (other than Borrowers)
have been fully reimbursed for all payments made under or relating to Letters of
Credit.

         2.12.    ADDITIONAL PAYMENTS.
                  -------------------

         Any sums expended by Agent or any Lender due to any Borrower's failure
to perform or comply with its obligations under this Agreement or any Other
Document including, without limitation, any Borrower's obligations under
Sections 4.12 and 4.13 hereof, may be charged to such Borrower's account as a
Revolving Advance and added to the Obligations, provided Agent shall promptly
thereafter provide to Borrowing Agent a copy of documentation supporting such
charges.

                                      25

         2.13.    MANNER OF BORROWING AND PAYMENT.
                  -------------------------------

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

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

         (c)      (i)    Notwithstanding anything to the contrary contained in
Sections 2.13(a) and (b) hereof, commencing with the first Business Day
following the Effective Date, each borrowing of Revolving Advances shall be
advanced by Agent and each payment by Borrowers on account of Revolving Advances
shall be applied first to those Revolving Advances made by Agent. On or before
1:00 P.M., New York time, on each Settlement Date commencing with the first
Settlement Date following the Effective Date, Agent and the Lenders shall make
certain payments as follows: (I) if the aggregate amount of new Revolving
Advances made by Agent during the preceding Week exceeds the aggregate amount of
repayments applied to outstanding Revolving Advances during such preceding Week
(if any), then each Lender shall provide Agent with funds in an amount equal to
its Commitment Percentage of the difference between (w) such Revolving Advances
and (x) such repayments and (II) if the aggregate amount of repayments applied
to outstanding Revolving Advances during such Week exceeds the aggregate amount
of new Revolving Advances made during such Week, then Agent shall provide each
Lender with funds in an amount equal to its Commitment Percentage of the
difference between (y) such repayments and (z) such Revolving Advances.

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

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

         (d)      If any Lender or any Transferee (a "benefited Lender") shall
at any time receive any payment of all or part of its Advances, or interest
thereon, or receive any Collateral in respect thereof (whether voluntarily or
involuntarily or by set-off) in a greater proportion than any such payment to
and Collateral received by any other Lender, if any, in respect of such other
Lender's Advances, or interest thereon, and such greater proportionate payment
or receipt of Collateral is not expressly permitted hereunder, such benefited
Lender shall purchase for cash from the other Lenders such portion of each such
other Lender's Advances, or shall provide such other Lender with the benefits of
any such Collateral, or the proceeds thereof as shall be

                                      26
<PAGE>

necessary to cause such benefited Lender to share the excess payment or benefits
of such Collateral or proceeds ratably with each of the Lenders; provided,
                                                                 --------
however, that if all or any portion of such excess payment or benefits is
-------
thereafter recovered from such benefited Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest Each Lender so purchasing a portion of another
Lender's Advances may exercise all rights of payment (including, without
limitation, rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

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

         (f)      Notwithstanding anything to the contrary contained herein, in
the event any Lender (x) has refused (which refusal constitutes a breach by such
Lender of its obligations under this Agreement) to make available its Commitment
Percentage of any Advance or (y) notifies either Agent or Borrowers that it does
not intend to make available its Commitment Percentage of any Advance (if the
actual refusal would constitute a breach by such Lender of its obligations under
this Agreement) (each, a "Lender Default"), all rights and obligations hereunder
of such Lender (a "Defaulting Lender") as to which a Lender Default is in effect
and of the other parties hereto shall be modified to the extent of the express
provisions of this Section 2.13(f) while such Lender Default remains in effect.

                  (i)    Revolving Advances shall be allocated pro rata among
                                                               --- ----
         Lenders (the "Non-Defaulting Lenders") which are not Defaulting Lenders
         in accordance with their respective Commitment Percentages, and no
         Commitment Percentage of any Lender or any pro rata share of any
                                                    --- ----
         Revolving Advances required to be advanced by any Lender shall be
         increased as a result of such Lender Default. Amounts received in
         respect of principal of Advances shall be applied to reduce Advances of
         each Lender pro rata based on the aggregate of the outstanding Advances
                     --- ----
         of all Lenders at the time of such application; provided that, such
         amount shall not be applied to any Advances of a

                                      27
<PAGE>

         Defaulting Lender at any time when, and to the extent that, the
         aggregate amount of Advances of any Lender that is not a Defaulting
         Lender exceeds such Lender's Commitment Percentage of all Advances then
         outstanding.

                  (ii)   Lenders shall participate in Letters of Credit on the
         basis of their respective pro rata shares, and no participation or
                                   --- ----
         reimbursement obligation of any Lender shall be increased as a result
         of a failure of any Defaulting Lender to reimburse Agent with respect
         to any amounts drawn on or otherwise payable with respect to any
         Letters of Credit (the amount that any such Defaulting Lender has
         failed to reimburse is hereinafter referred to as such Defaulting
         Lender's "Unreimbursed Amount"). Until such Defaulting Lender has
         reimbursed Agent for any Unreimbursed Amount owed by it, all payments
         and other amounts received from any source with respect to the
         Obligations or otherwise under or in connection with this Agreement
         (including any letter of credit fees) which would otherwise be payable
         to such Defaulting Lender will instead be paid to Agent for application
         to such Unreimbursed Amount until such Unreimbursed Amount has been
         paid in full. A Defaulting Lender shall not be entitled to receive any
         portion of the letter of credit fees or any other fees payable in
         connection with this Agreement, or any indemnity arising from its
         agreement to make Revolving Advances and/or participate in Letters of
         Credit hereunder.

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

                  (iv)   Other than as expressly set forth in this Section
         2.13(f), the rights and obligations of a Defaulting Lender (including
         the obligation to indemnify Agent) and the other parties hereto shall
         remain unchanged. Nothing in this Section 2.13(f) shall be deemed to
         release any Defaulting Lender from its obligations under this Agreement
         or the Other Documents, shall alter such obligations, shall operate as
         a waiver of any default by such Defaulting Lender hereunder, or shall
         prejudice any rights which any Borrower, Agent or any Lender may have
         against any Defaulting Lender as a result of any default by such
         Defaulting Lender hereunder.

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

         2.15.    USE OF PROCEEDS.
                  ---------------

         Borrowers shall apply the proceeds of Advances to (i) repay existing
indebtedness owed to Bank of America, N.A., (ii) pay fees and expenses relating
to this transaction, and (iii) to provide for their working capital needs and
other corporate purposes.

         2.16.    DEFAULTING LENDER.
                  -----------------

                  (a)    Notwithstanding anything to the contrary contained
herein, in the event any Lender (x) has refused (which refusal constitutes a
breach by such Lender of its obligations under this Agreement) to make available
its portion of any Advance or (y) notifies either Agent or Borrowing Agent that
it does not intend to make available its portion of any Advance (if the actual
refusal would constitute a breach by such Lender of its obligations under this
Agreement) (each, a "Lender Default"), all rights and obligations hereunder of
such Lender (a "Defaulting Lender") as to which a Lender Default is in effect
and of the other parties hereto shall be modified to the extent of the express
provisions of this Section 2.16 while such Lender Default remains in effect.

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

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

                  (d)    Other than as expressly set forth in this Section
2.16, the rights and obligations of a Defaulting Lender (including the
obligation to indemnify Agent) and the other parties hereto shall remain
unchanged. Nothing in this Section 2.16 shall be deemed to release any
Defaulting Lender from its obligations under this Agreement and the Other
Documents, shall alter such obligations, shall operate as a waiver of any
default by such Defaulting Lender hereunder, or shall prejudice any rights which
any Borrower, Agent or any Lender may have against any Defaulting Lender as a
result of any default by such Defaulting Lender hereunder.

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

III      INTEREST AND FEES.
         -----------------

         3.1.     INTEREST.
                  --------

         Interest on Advances shall be payable in arrears on the last day of
each month with respect to Domestic Rate Loans and, with respect to Eurodollar
Rate Loans, at the end of each Interest Period or, for Eurodollar Rate Loans
with an Interest Period in excess of three months, at the earlier of (a) the
last day of each three month period from the date of the commencement of such
Eurodollar Rate Loan or (b) the end of the Interest Period. Interest charges
shall be computed on the actual principal of Advances outstanding during the
month (the "Monthly Advances") at a rate per annum equal to the applicable
Contract Rate. Whenever, subsequent to the date of this Agreement, the Alternate
Base Rate is increased or decreased, the applicable Contract Rate with respect
to Domestic Rate Loans shall be similarly changed without notice or demand of
any kind by an amount equal to the amount of such change in the Alternate Base
Rate during the time such change or changes remain in effect. Upon and after the
occurrence of an Event of Default, and during the continuation thereof, the
Obligations shall bear interest at the applicable Revolving Interest Rate plus
two (2%) percent per annum (the "Default Rate"). So long as no Default or Event
of Default shall have occurred and be continuing, the Applicable Margin shall be
increased or decreased, as the case may be, as of the first day of each fiscal
quarter following the fiscal quarter reported upon in the financial statements
delivered pursuant to Sections 9.8 and 9.9 hereof, commencing with fiscal
quarter ending June 28, 2002 based upon the Fixed Charge Coverage Ratio with
respect to the four (4) fiscal quarters then ended as reported upon in the
applicable financial statements.

         3.2.     LETTER OF CREDIT FEES.
                  ---------------------

         Borrowers shall pay Agent (i) for the ratable benefit of the Lenders
for issuing or causing the issuance of a Standby Letter of Credit, a fee
computed at a rate per annum of one and three quarters percent (1.75%) on the
outstanding amount thereof from time to time, (ii) for the ratable benefit of
the Lenders for issuing or causing the issuance of a Documentary Letter of
Credit, a fee equal to one quarter percent (.25%) of the face amount thereof,
(iii) for its own account, a letter of credit fronting and negotiation fee of
..125% per annum on the maximum amount available to be drawn under each Letter of
Credit, payable upon the issuance of each such Letter of Credit, and (iv) Bank's
other customary charges payable in connection with Letters of Credit as in
effect from time to time (which charges shall be furnished to Borrowers by Agent
upon request). Such fees and charges shall be payable in the case of any Letter
of Credit, on its opening monthly thereafter in advance and upon each increase
in the outstanding amount thereof. Any such charge in effect at the time of a
particular transaction shall be the charge for that transaction, notwithstanding
any subsequent change in Bank's prevailing charges for that type of transaction.
All Letter of Credit Fees payable hereunder shall be deemed earned in full on
the

                                      30
<PAGE>

date when the same are due and payable hereunder and shall not be subject to
rebate or proration upon the termination of this Agreement for any reason.

         Upon the occurrence and during the continuance of an Event of Default,
Borrowers will cause cash to be deposited and maintained in an account with
Agent, as cash collateral, in an amount equal to one hundred percent (100%) of
the outstanding Letters of Credit and each Borrower hereby irrevocably
authorizes Agent, in its discretion, on such Borrower's behalf and in such
Borrower's name, to open such an account and to make and maintain deposits
therein, or in an account opened by such Borrower, in the amounts required to
be made by such Borrower, out of the proceeds of Receivables or other
Collateral or out of any other funds of such Borrower coming into any Lender's
possession at any time. Agent will invest such cash collateral (less applicable
reserves) in such short-term money-market items as to which Agent and such
Borrower mutually agree and the net return on such investments shall be
available for withdrawal by Borrowers. Except as provided for in the
immediately preceding sentence, no Borrower may withdraw amounts credited to
any such account except upon payment and performance in full of all Obligations
and termination of this Agreement.

         3.3.     FEES.
                  ----

         (a)      Facility Fee.

                  If, for any month during the Term, the average daily unpaid
         balance of the Revolving Advances for each day of such month plus
                                                                      ----
         outstanding Letters of Credit does not equal the Maximum Loan Amount
         then Borrowers shall pay to Agent for the ratable benefit of the
         Lenders a fee at a rate equal to three-eighths of one percent (.375%)
         per annum on the amount by which the Maximum Loan Amount exceeds such
         average daily unpaid balance plus outstanding Letters of Credit. Such
         fee shall be payable to Agent in arrears on the last day of each month
         and on the last day of the Term.

                                      31
<PAGE>

         3.4.     COLLATERAL EVALUATION AND MONITORING FEES.
                  -----------------------------------------

         (a)      Collateral Evaluation Fee. Borrower shall pay to Agent (for
                  -------------------------
the sole benefit of Agent) an collateral evaluation fee equal to $1,500 per
month payable on the first day of each month commencing on the first day of the
month following the Effective Date and on the first day of each month
thereafter during the Term. The collateral evaluation fee shall be deemed
earned in full on the date when same is due and payable hereunder and shall not
be subject to rebate or proration upon termination of this Agreement for any
reason.

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

         3.5.     COMPUTATION OF INTEREST AND FEES.
                  --------------------------------

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

         3.6.     MAXIMUM CHARGES.
                  ---------------

         In no event whatsoever shall interest and other charges charged
hereunder exceed the highest rate permissible under law which a court of
competent jurisdiction shall, in a final determination, deem applicable hereto.
In the event that a court determines that Agent or any Lender has received
interest and other charges hereunder in excess of the highest rate permissible
hereto, such excess amount shall be first applied to any unpaid principal
balance owed by Borrowers, and if the then remaining excess amount is greater
than the previously unpaid principal balance, the Lenders shall promptly refund
such excess amount to Borrowers and the provisions hereof shall be deemed
amended to provide for such permissible rate.

         3.7.     INCREASED COSTS.
                  ---------------

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

                                      32
<PAGE>

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

         (b)      change the currency of a country, impose, modify or hold
applicable any reserve, special deposit, assessment or similar requirement
against assets held by, or deposits in or for the account of, advances or loans
by, or other credit extended by, any office of Agent or any Lender, including
(without limitation) pursuant to Regulation D of the Board of Governors of the
Federal Reserve System; or

         (c)      impose on Agent or any Lender or the London interbank
Eurodollar market any other condition with respect to this Agreement, any Other
Documents or any Eurodollar Rate Loan; and the result of any of the foregoing
is to increase the cost to Agent or Lender of making, renewing or maintaining
its Advances hereunder by an amount that Agent or such Lender deems to be
material or to reduce the amount of any payment (whether of principal, interest
or otherwise) in respect of any of the Advances by an amount that Agent or such
Lender deems to be material, then, in any case Borrowers shall promptly pay
Agent or such Lender, upon its demand, such additional amount as will
compensate Agent or such Lender for such additional cost or such reduction, as
the case may be, provided that the foregoing shall not apply to increased costs
which are reflected in the Alternate Base Rate or the Eurodollar Rate, as the
case may be. Agent or such Lender shall certify the amount of such additional
cost or reduced amount to Borrowing Agent, and such certification shall be
conclusive absent manifest error.

         3.8.     BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR.
                  --------------------------------------------------------

         In the event that Agent or any Lender shall have determined that:

         (a)      reasonable means do not exist for ascertaining the Eurodollar
Rate for any Interest Period; or

         (b)      Dollar deposits in the relevant amount and for the relevant
maturity are not available in the London interbank Eurodollar market, with
respect to an outstanding Eurodollar Rate Loan, a proposed Eurodollar Rate
Loan, or a proposed conversion of a Domestic Rate Loan into a Eurodollar Rate
Loan;

Agent shall give Borrowing Agent prompt written, telephonic or telegraphic
notice of such determination. If such notice is given, (i) any such requested
Eurodollar Rate Loan shall be made as a Domestic Rate Loan, unless Borrowing
Agent shall notify Agent no later than 10:00 a.m. (New York City time) two (2)
Business Days prior to the date of such proposed borrowing, that its request
for such borrowing shall be cancelled or made as an unaffected type of
Eurodollar Rate Loan, (ii) any Domestic Rate Loan or Eurodollar Rate Loan which
was to have been converted to an affected type of Eurodollar Rate Loan shall be
continued as or converted into a

                                      33
<PAGE>

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

         3.9.     CAPITAL ADEQUACY.
                  ----------------

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

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

                                      34
<PAGE>

WITH A LOAN OR OTHER FINANCIAL TRANSACTION FOR BUSINESS PURPOSES AND NOT
PRIMARILY FOR PERSONAL, FAMILY OR HOUSEHOLD PURPOSES. THE AGENT, AS AGENT FOR
THE GRANTOR UNDER THE POWERS OF ATTORNEY, IS NOT A FIDUCIARY FOR THE GRANTOR.
THE AGENT, IN EXERCISING ANY OF ITS RIGHTS OR POWERS PURSUANT TO THE POWERS OF
ATTORNEY, MAY DO SO FOR THE SOLE BENEFIT OF AGENT AND NOT FOR THE GRANTOR. THE
PARTIES ACKNOWLEDGE AND AGREE THAT THE PROVISIONS OF TITLE 20 PA.C.S. CHAPTER
56, AS AMENDED (SPECIFICALLY INCLUDING, ACT 39 OF 1994) SHALL NOT BE APPLICABLE
TO THE POWERS OF ATTORNEY.

         For the purpose of this Article IV, references herein to the "Agent"
shall be deemed to mean "the Agent, for the ratable benefit of the Lenders".

         EACH BORROWER HAS NEVERTHELESS READ, UNDERSTANDS AND KNOWINGLY AND
VOLUNTARILY ACCEPTS AND AGREES TO SUCH PROVISIONS CONTAINING POWERS OF ATTORNEY
RECOGNIZING THAT CERTAIN IMPORTANT RIGHTS MAY BE RELINQUISHED IF ANY SUCH
POWERS ARE EXERCISED.

         4.1.     ACKNOWLEDGEMENT AND GRANT OF SECURITY INTERESTS.
                  -----------------------------------------------

         (a)      Each Borrower hereby acknowledges, confirms and agrees that
Agent for the ratable benefit of Lenders has and shall continue to have a lien
upon and security interest in all Collateral heretofore granted to Agent
pursuant to the Existing Loan Agreement to secure the Obligations and, to the
extent not otherwise granted thereunder or under the Other Documents or
otherwise granted to or held by Agent. Each Borrower hereby pledges and assigns
to Agent for the ratable benefit of Lenders and grants to Agent for the ratable
benefit of Lenders a continuing security interest to secure the Obligations, in
all of such Borrower's Collateral, wherever located, whether in any Borrower's
possession or in the possession and control of a third party for any Borrower's
or Agent's or any Lender's account. All of each Borrower's ledger sheets,
files, records, books of account, business papers and documents relating to the
Collateral shall, until delivered to or removed by Agent, be kept by such
Borrower in trust for Agent for the ratable benefit of Lenders.

         (b)      The liens and security interests of Agent for the ratable
benefit of Lenders in the Collateral shall be deemed to be continuously
perfected from the earliest date of the granting of such liens and security
interests, whether hereunder, under the Other Documents, or under the Existing
Loan Agreement.

         4.2.     PERFECTION OF SECURITY INTEREST.
                  -------------------------------

         Each Borrower shall take all action that may be necessary or
desirable, or that Agent may request, so as at all times to maintain the
validity, perfection, enforceability and priority of Agent's security interest
for the ratable benefit of the Lenders in the Collateral or to enable Agent to
protect, exercise or enforce its rights hereunder and in the Collateral,
including, but not limited to (i) immediately discharging all Liens other than
Permitted Encumbrances, (ii)

                                      35

obtaining landlords' or mortgagees' lien waivers, (iii) delivering to Agent,
endorsed or accompanied by such instruments of assignment as Agent may specify,
and stamping or marking, in such manner as Agent may specify, any and all
chattel paper, instruments, letters of credits and advices thereof and
documents evidencing or forming a part of the Collateral, (iv) entering into
warehousing, lockbox and other custodial arrangements satisfactory to Agent,
and (v) executing and delivering financing statements, instruments of pledge,
mortgages, notices and assignments, in each case in form and substance
satisfactory to the Required Lenders, relating to the creation, validity,
perfection, maintenance or continuation of Agent's security interest for the
ratable benefit of the Lenders under the Uniform Commercial Code or other
applicable law. Agent is hereby authorized to file financing statements
covering the Collateral without any Borrowers signature in accordance with the
Uniform Commercial Code as adopted in the Common wealth of Pennsylvania. All
charges, expenses and fees Agent may incur in doing any of the foregoing, and
any local taxes relating thereto, shall be paid to Agent for the ratable
benefit of the Lenders immediately upon demand.

         4.3.     DISPOSITION OF COLLATERAL.
                  -------------------------

         Each Borrower will safeguard and protect all Collateral granted by
such Borrower for Agent's general account and make no disposition thereof
whether by sale, lease or otherwise except the sale of Inventory in the
ordinary course of business.

         4.4      PRESERVATION OF COLLATERAL.
                  --------------------------

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

         4.5.     OWNERSHIP OF COLLATERAL.
                  -----------------------

         With respect to the Collateral, at the time the Collateral becomes
subject to Agent's security interest for its benefit and for the ratable
benefit of the Lenders: (a) each Borrower shall be the sole owner of and fully
authorized and able to sell, transfer, pledge and/or grant a first security
interest in each and every item of the Collateral to Agent for its benefit and
for the

                                      36
<PAGE>

ratable benefit of the Lenders; and, except for Permitted Encumbrances the
Collateral shall be free and clear of all Liens and encumbrances whatsoever;
(b) each document and agreement executed by each Borrower or delivered to Agent
or any Lender in connection with this Agreement shall be true and correct in
all respects; (c) all signatures and endorsements of each Borrower that appear
on such documents and agreements shall be genuine and each Borrower shall have
full capacity to execute same; and (d) each Borrower's Inventory shall be
located as set forth on Schedule 4.5 and shall not be removed from such
                        ------------
location(s) without the prior written consent of Agent except with respect to
the sale of Inventory in the ordinary course of business.

         4.6.     DEFENSE OF AGENT'S AND LENDER'S INTERESTS.
                  -----------------------------------------

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

         4.7.     BOOKS AND RECORDS.
                  -----------------

         Each Borrower (a) shall keep proper books of record and account in
which full, true and correct entries will be made of all dealings or
transactions of or in relation to its business and affairs; (b) set up on its
books accruals with respect to all taxes, assessments, charges, levies and
claims; and (c) on a reasonably current basis set up on its books, from its
earnings, allowances against doubtful Receivables as the case may be, advances
and investments and all other proper accruals (including without limitation by
reason of enumeration, accruals for premiums, if any, due on required payments
and accruals for depreciation, obsolescence, or amortization of

                                      37
<PAGE>

properties), which should be set aside from such earnings in connection with
its business. All determinations pursuant to this subsection shall be made in
accordance with, or as required by, GAAP consistently applied in the opinion of
such independent public accountant as shall then be regularly engaged by
Borrowers.

         4.8.     FINANCIAL DISCLOSURE.
                  --------------------

         Each Borrower hereby irrevocably authorizes and directs all
accountants and auditors employed by Borrowers at any time during the Term to
exhibit and deliver to Agent and each Lender copies of any Borrower's financial
statements, trial balances or other accounting records of any sort in the
accountant's or auditor's possession, and to disclose to Agent and each Lender
any information such accountants may have concerning any Borrower's financial
status and business operations. Each Borrower hereby authorizes all federal,
state and municipal authorities to furnish to Agent and each Lender copies of
reports or examinations relating to Borrowers, whether made by a Borrower or
otherwise; however, Agent and each Lender will attempt to obtain such
information or materials directly from Borrowers, as the case may be, prior to
obtaining such information or materials from such accountants or such
authorities.

         4.9.     COMPLIANCE WITH LAWS.
                  --------------------

         Each Borrower shall comply in all material respects with all acts,
rules, regulations and orders of any legislative, administrative or judicial
body or official applicable to the Collateral or any part thereof or to the
operation of such Borrower's business the noncompliance with which could have a
Material Adverse Effect on such Borrower. Each Borrower may, however, contest
or dispute any acts, rules, regulations, orders and directions of those bodies
or officials in any reasonable manner, provided that any related lien is
inchoate or stayed and sufficient reserves are established to the reasonable
satisfaction of the Lenders to protect Agent's Lien on or security interest in
the Collateral. The Collateral at all times shall be maintained in accordance
with the requirements of all insurance carriers which provide insurance with
respect to the Collateral so that such insurance shall remain in full force and
effect.

         4.10.    INSPECTION OF PREMISES.
                  ----------------------

         At all reasonable times Agent and each Lender shall have full access
to and the right to audit, check, inspect and make abstracts and copies from
any Borrower's books, records, audits, correspondence and all other papers
relating to the Collateral and the operation of their respective businesses.
Agent, any Lender and their agents may enter upon any Borrower's premises at
any time during business hours and at any other reasonable time, and from time
to time without prior notice, for the purpose of inspecting the Collateral and
any and all records pertaining thereto and the operation of their respective
businesses.

         4.11.    INSURANCE.
                  ---------

         Each Borrower shall bear the full risk of any loss of any nature
whatsoever with respect to the Collateral. At Borrowers' own cost and expense
in amounts and with carriers acceptable

                                      38
<PAGE>

to Agent, each Borrower shall (a) keep all insurable properties and properties
in which it has an interest insured against the hazards of fire, flood,
sprinkler leakage, those hazards covered by extended coverage insurance and
such other hazards, and for such amounts, as is customary in the case of
companies engaged in similar businesses including, without limitation, business
interruption insurance; (b) maintain a bond in such amounts as is customary in
the case of companies engaged in similar businesses insuring against larceny,
embezzlement or other criminal misappropriation of insured's officers and
employees who may either singly or jointly with others at any time have access
to the assets or funds of Borrowers either directly or through authority to
draw upon such funds or to direct generally the disposition of such assets; (c)
maintain public and product liability insurance against claims for personal
injury, death or property damage suffered by others; (d) maintain all such
worker's compensation or similar insurance as may be required under the laws of
any state or jurisdiction in which it is engaged in business; (e) furnish Agent
with (i) copies of all policies and evidence of the maintenance of such
policies by the renewal thereof at least thirty (30) days before any expiration
date, and (ii) appropriate loss payable endorsements in form and substance
satisfactory to Agent, naming Agent as a co-insured and loss payee as its
interests may appear with respect to all insurance coverage referred to in
clauses (a) and (b) above, and providing (A) that all proceeds thereunder in
excess of $100,000 shall be payable to Agent for the ratable benefit of the
Lenders, (B) no such insurance shall be affected by any act or neglect of the
insured or owner of the property described in such policy, and (C) that such
policy and loss payable clauses may not be cancelled, amended or terminated
unless at least thirty (30) days' prior written notice is given to Agent. In
the event of any loss thereunder, the carriers named therein hereby are
directed by Agent or any Borrower to make payment for such loss in excess of
$100,000 to Agent and not to a Borrower and Agent jointly. If any insurance
losses are paid by check, draft or other instrument payable to a Borrower and
Agent jointly, Agent may endorse such Borrower's name thereon and do such other
things as Agent may deem advisable to reduce the same to cash. Agent is hereby
authorized to adjust and compromise claims under insurance coverage referred to
in clauses (a) and (b) above. All loss recoveries received by Agent upon any
such insurance related to Collateral may be applied to the Obligations, in such
order as Agent in its sole discretion shall determine; provided, upon any
                                                       --------
Borrower's request such proceeds shall be disbursed to such Borrower for the
restoration of damaged property if such proceeds together with other amounts
provided by such Borrower are sufficient to fully restore such property to its
condition prior to the casualty loss. Any surplus shall be paid by Agent to
Borrowers or applied as may be otherwise required by law. Any deficiency
thereon shall be paid by Borrowers, to Agent, on demand.

         4.12.    FAILURE TO PAY INSURANCE.
                  ------------------------

         If any Borrower shall fail to obtain insurance as hereinabove
provided, or to keep the same in force, Agent, if Agent so elects, may obtain
such insurance and pay the premium therefor for such Borrower's account, and
charge such Borrower's account therefor and such expenses so paid shall be part
of the Obligations, provided Agent shall promptly thereafter provide to such
Borrower documentation supporting such charges.

                                      39
<PAGE>

         4.13.    PAYMENT OF TAXES.
                  ----------------

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

         4.14.    PAYMENT OF LEASEHOLD OBLIGATIONS.
                  --------------------------------

         Each Borrower shall at all times pay, when and as due, its rental
obligations under all leases under which it is a tenant, and shall otherwise
comply, in all material respects, with all other terms of such leases and keep
them in full force and effect and, at Agent's request, will provide evidence of
having done so.

         4.15.    RECEIVABLES.
                  -----------

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

                  (b)      Solvency of Customers. Each Customer of each
                           ---------------------
Borrower, to the best of such Borrower's knowledge, as of the date each
Receivable is created, is and will be solvent and able to pay all Receivables on
which the Customer is obligated in full when due or with respect to such
Customers of such Borrower who are not solvent such Borrower has set up on its
books and in its financial records bad debt reserves adequate to cover such
Receivables.

                  (c)      Locations of Borrower. Each Borrower's chief
                           ---------------------
executive office and the office at which each maintains its books and records
pertaining to Receivables is the address set

                                      40
<PAGE>

forth on Schedule 4.15(c) hereto. Until written notice is given to Agent by
         ---------------
Borrowing Agent of any other office at which it keeps its records pertaining to
Receivables all such records shall be kept at such offices.

                 (d)      Collection of Receivables. Until a Borrower's
                          -------------------------
authority to do so is terminated by Agent (which notice Agent may give at any
time following the occurrence of an Event of Default or a Default), such
Borrower will, at its sole cost and expense, but on Agent's behalf and for
Agent's account, collect as Agent's property and in trust for Agent all amounts
received on Receivables of such Borrower, and shall not commingle such
collections with its respective funds or use the same except to pay Obligations.
Each Borrower shall, upon request, deliver to Agent or the Blocked Account in
original form and on the date of receipt thereof, all checks, drafts, notes,
money orders, acceptances, cash and other evidences of Indebtedness received by
such Borrower.

                  (e)      Notification of Assignment of Receivables. At any
                           -----------------------------------------
time, if Agent, in its sole discretion, believes that failure to send such
notice could impair Lenders rights in the Collateral or Agent's receipt of any
proceeds of the Collateral, or if Agent otherwise deems Lenders insecure or, at
any time after an Event of Default, Agent shall have the right to send notice of
the assignment of, and Agent's security interest in, the Receivables of the
Borrowers to any and all Customers or any third party holding or otherwise
concerned with any of the Collateral. After an Event of Default and after giving
such notice, Agent shall have the sole right to collect the Receivables, take
possession of the Collateral or both, for the ratable benefit of the Lenders, to
be applied to the Obligations. Agent's actual collection expenses, including,
but not limited to, stationery and postage, telephone and telegraph, secretarial
and clerical expenses and the salaries of any collection personnel used for
collection, may be charged to Borrower's accounts and added to the Obligations.

                  (f)      Power of Agent to Act on Borrowers' Behalf. Agent
                           ------------------------------------------
shall have the right to receive, endorse, assign and/or deliver in the name of
Agent, or any Borrower any and all checks, drafts and other instruments for the
payment of money relating to the Receivables and Borrower hereby waives notice
of presentment, protest and non-payment of any instrument so endorsed. Each
Borrower hereby constitutes Agent or Agent's designee as its respective attorney

acceptances, checks, drafts, money orders or other evidences of payment or

similar document in connection with the Receivables of the Borrowers; and (B) at
any time (i) to send verifications of Receivables of the Borrowers to any

                                      41
<PAGE>

Customer; (ii) to sign its name on all financing statements or any other
documents or instruments deemed necessary or appropriate by Agent to preserve,
protect, or perfect Agent's interest in the Collateral and to file same; (iii)
to do all other acts and things necessary to carry out this Agreement. All acts
of said attorney or designee are hereby ratified and approved, and said attorney
or designee shall not be liable for any acts of omission or commission nor for
any error of judgment or mistake of fact or of law, unless done maliciously or
with gross (not mere) negligence; this power being coupled with an interest is
irrevocable while any of the Obligations remain unpaid. Agent shall have the
right at any time following the occurrence and during the continuance of an
Event of Default, to change the address for delivery of mail addressed to any
Borrower to such address as Agent may designate.

                  (g)      No Liability. Neither Agent nor any Lender shall,
                           ------------
under any circumstances or in any event whatsoever, have any liability for any
error or omission or delay of any kind occurring in the settlement, collection
or payment of any of the Receivables or any instrument received in payment
thereof, or for any damage resulting therefrom. Following the occurrence and
during the continuance of an Event of Default Agent may, without notice or
consent from any Borrower, sue upon or otherwise collect, extend the time of
payment of, compromise or settle for cash, credit or upon any terms any of the
Receivables or any other securities, instruments or insurance applicable thereto
and/or release any obligor thereof. Agent is authorized and empowered to accept
following the occurrence and during the continuance of an Event of Default the
return of the goods represented by any of the Receivables, without notice to or
consent by any Borrower, all without discharging or in any way affecting the
Obligations hereunder.

                  (h)      Establishment of a Lockbox Account, Dominion Account.
                           ----------------------------------------------------
All proceeds of Collateral shall, at the direction of Agent, be deposited by
Borrowers into a lockbox account, dominion account or such other "blocked
account" ("Blocked Accounts") as Agent may require pursuant to an arrangement
with such bank(s) as may be selected by Borrowers and be acceptable to Agent.
Borrowers shall issue to any such bank, an irrevocable letter of instruction
directing said bank to transfer such funds so deposited to Agent, either to any
account maintained by Agent at said bank or by wire transfer to appropriate
account(s) of Agent. All funds deposited in such Blocked Account shall
immediately become the property of Agent and Borrowers shall obtain the
agreement by such bank to waive any offset rights against the funds so
deposited. Neither Agent nor any Lender assumes any responsibility for such
"blocked account" arrangement including, without limitation, any claim of accord
and satisfaction or release with respect to deposits accepted by any bank
thereunder. Alternatively, Agent may establish depository accounts ("Depository
Accounts") in the name of Agent at a bank or banks for the deposit of such funds
and Borrowers shall deposit all proceeds of Collateral or cause same to be
deposited, in kind, in such Depository Accounts of Agent in lieu of depositing
same to the Blocked Accounts.

                  (i)      Adjustments. No Borrower will, without Agent's
                           -----------
consent, compromise or adjust any Receivables (or extend the time for payment
thereof) or accept any material returns of merchandise or grant any additional
discounts, allowances or credits thereon except for those

                                      42
<PAGE>

compromises, adjustments, returns, discounts, credits and allowances as have
been heretofore customary in the business of such Borrower, as the case may
be.

         4.16.    INVENTORY.
                  ---------

         All Inventory has been, and will be, produced by Borrowers in
compliance with the Federal Fair Labor Standards Act of 1938 (to the extent
applicable to such Borrower), as amended, and all rules, regulations and orders
thereunder.

         4.17.    INTENTIONALLY OMITTED.

         15.1.    GOVERNING LAW.
                  -------------

         This Agreement shall be governed by and construed in accordance with
the laws of the Commonwealth of Pennsylvania applied to contracts to be
performed wholly within the Commonwealth of Pennsylvania. Any judicial
proceeding brought by or against any Borrower with respect to any of the
Obligations, this Agreement or any related agreement may be brought in any
court of competent jurisdiction in the Commonwealth of Pennsylvania, United
States of America, and, by execution and delivery of this Agreement, each
Borrower each accepts for itself and in connection with its properties,
generally and unconditionally, the non-exclusive jurisdiction of the aforesaid
courts, and irrevocably agrees to be bound by any judgment rendered thereby in
connection with this Agreement. Each Borrower hereby waives personal service of
any and all process upon it and consents that all such service of process may
be made by registered mail (return receipt requested) directed to Borrowing
Agent at its address set forth in Section 15.6. Nothing herein shall affect the
right to serve process in any manner permitted by law or shall limit the right
of the Agent to bring proceedings against any Borrower in the courts

of any other jurisdiction. Each Borrower waives any objection to jurisdiction
and venue of any action instituted hereunder and shall not assert any defense
based on lack of jurisdiction or venue or based upon forum non conveniens. Any
                                                     --------------------
judicial proceeding by any Borrower against the Agent or Lenders involving,
directly or indirectly, any matter or claim in any way arising out of: related
to or connected with this Agreement or any related agreement, shall be brought
only in a federal or state court located in the County of Montgomery or
Philadelphia, Commonwealth of Pennsylvania.

         15.2     ENTIRE UNDERSTANDING.
                  --------------------

                  (a)      This Agreement and the documents executed
concurrently herewith contain the entire understanding between Borrowers, Agent
and each Lender and supersedes all prior agreements and understandings, if any,
relating to the subject matter hereof. Any promises, representations,
warranties or guarantees not herein contained and hereinafter made shall have
no force and effect unless in writing, signed by each Borrower's, Agent's and
each Lender's respective officers. Neither this Agreement nor any portion or
provisions hereof may be changed, modified, amended, waived, supplemented,
discharged, cancelled or terminated orally or by any course of dealing, or in
any manner other than by an agreement in writing, signed by the party to be
charged. Each Borrower acknowledges that it has been advised by counsel in
connection with the execution of this Agreement and Other Documents and is not
relying upon oral representations or statements inconsistent with the terms and
provisions of this Agreement.

                                      77

                  (b)      The Required Lenders, Agent with the consent in
writing of the Required Lenders, and each Borrower may, subject to the
provisions of this Section 15.2(b), from time to time enter into written
supplemental agreements to this Agreement, the Note or the Other Documents
executed by Borrowers, for the purpose of adding or deleting any provisions or
otherwise changing, varying or waiving in any manner the rights of the Lenders,
Agent or any Borrower thereunder or the conditions, provisions or terms thereof
or waiving any Event of Default thereunder, but only to the extent specified in
such written agreements; provided, however, that no such supplemental agreement
                         --------  -------
shall (x) amend Sections 6.5, 6.6 or 7.6 without the consent of 67% of the
Lenders or (y) without the consent of all the Lenders:

                           (i)      increase or decrease the Commitment
Percentage of any Lender or the Maximum Loan Amount or the Advance Rates.

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

                           (iii)    alter the definition of the term Required
Lenders or alter, amend or modify this Section 15.2(b).

                           (iv)     release any Collateral during any calendar
year having an aggregate value in excess of $500,000.

                           (v)      change the rights and duties of Agent.

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

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

In the event that Agent requests the consent of a Lender pursuant to this
Section 16.2 and such Lender shall not respond or reply to Agent in writing
within ten (10) days of delivery of such request, such Lender shall be deemed
to have consented to matter that was the subject of the request. In the event
that Agent requests the consent of a Lender pursuant to this Section 16.2 and
such consent is denied, then PNC may, at its option, require such Lender to
assign its interest in the Advances to PNC or to another Lender or to any other
Person designated by the Agent (the

                                      78
<PAGE>

"Designated Lender"), for a price equal to the then outstanding principal amount
thereof plus accrued and unpaid interest and fees due such Lender, which
interest and fees shall be paid when collected from Borrowers. In the event PNC
elects to require any Lender to assign its interest to PNC or to the Designated
Lender, PNC will so notify such Lender in writing within forty five (45) days
following such Lender's denial, and such Lender will assign its interest to PNC
or the Designated Lender no later than five (5) days following receipt of such
notice pursuant to a Commitment Transfer Supplement executed by such Lender, PNC
or the Designated Lender, as appropriate, and Agent.

Notwithstanding (a) the existence of a Default or an Event of Default, (b) that
any of the other applicable conditions precedent set forth in Section 8.2
hereof have not been satisfied or (c) any other provision of this Loan
Agreement, Agent may at its discretion and without the consent of the Required
Lenders, voluntarily permit the outstanding Revolving Advances at any time to
exceed the Formula Amount by up to one hundred and ten percent (110%) of the
Formula Amount for up to thirty (30) consecutive Business Days. For purposes of
the preceding sentence, the discretion granted to Agent hereunder shall not
preclude involuntary overadvances that may result from time to time due to the
fact that the Formula Amount was unintentionally exceeded for any reason,
including, but not limited to, Collateral previously deemed to be either
"Eligible Receivables" or "Eligible Inventory", as applicable, becomes
ineligible, collections of Receivables applied to reduce outstanding Revolving
Advances are thereafter returned for insufficient funds [or overadvances are
made to protect or preserve the Collateral.] In the event Agent involuntarily
permits the outstanding Revolving Advances to exceed the [Formula Amount] [or
Overadvance Threshold Amount] by more than ten percent (10%), Agent shall use
its efforts to have Borrowers decrease such excess in as expeditious a manner
as is practicable under the circumstances and not inconsistent with the reason
for such excess. Revolving Advances made after Agent has determined the
existence of involuntary overadvances shall be deemed to be involuntary
overadvances and shall be decreased in accordance with the preceding sentence.

In addition to (and not in substitution of) the discretionary Revolving Advances
permitted above in this Section 16.2, the Agent is hereby authorized by the
Borrowers and the Lenders, from time to time in the Agent's sole discretion, (A)
after the occurrence and during the continuation of a Default or an Event of
Default, or (b) at any time that any of the other applicable conditions
precedent set forth in Section 8.2 hereof have not been satisfied, to make
Revolving Advances to the Borrowers on behalf of the Lenders which the Agent, in
its reasonable business judgment, deems necessary or desirable (a) to preserve
or protect the Collateral, or any portion thereof, (b) to enhance the likelihood
of, or maximize the amount of, repayment of the Advances and other Obligations,
or (iii) to pay any other amount chargeable to the Borrowers pursuant to the
terms of this Agreement; provided, that at any time after giving effect to any
such Revolving Advances the outstanding Revolving Advances do not exceed one
hundred and ten percent (110%) of the Formula Amount.

         15.3     SUCCESSORS AND ASSIGNS; PARTICIPATIONS; NEW LENDERS.
                  ---------------------------------------------------

                  (a)      This Agreement shall be binding upon and inure to the
         benefit of Borrowers, Agent, each Lender, all future holders of the
         Note and their respective successors and assigns, except that no
         Borrower may assign or transfer any of its rights or obligations under
         this Agreement without the prior written consent of Agent and Lenders
         holding at least [seventy-six percent (76%)] of the Advances or if no
         Advances are outstanding, [seventy-six percent (76%)] of the Commitment
         Percentages.

                  (b)      Each Borrower acknowledges that in the regular course
         of commercial banking business one or more Lenders may at any time and
         from time to time sell participating interests in the Advances to other
         financial institutions (each such transferee or purchaser of a
         participating interest, a "Transferee"), subject to the prior written
         consent of Radnor which shall not be unreasonably withheld or delayed.
         Each Transferee may exercise all rights of payment (including without
         limitation rights of set-off) with respect to the portion of such
         Advances held by it or other Obligations payable hereunder as fully as
         if such Transferee were the direct holder thereof provided that
         Borrowers shall not be required to pay to any Transferee more than the
         amount which it would have been required to pay to the Lender which
         granted an interest in its Advances or other Obligations payable
         hereunder to such Transferee had such Lender retained such interest in
         the Advances hereunder or other Obligations payable hereunder and in no
         event shall Borrowers be required to pay any such amount arising from
         the same circumstances and with respect to the same Advances or other
         Obligations payable hereunder to both such Lender and such Transferee.
         Each Borrower hereby grants to any Transferee a continuing security
         interest in any deposits, moneys or other property actually or
         constructively held by such Transferee as security for the Transferee's
         interest in the Advances.

                  (c)      Subject to the prior written consent of Radnor, which
         shall not be unreasonable withheld or delayed, any Lender may with the
         consent of Agent which shall not be unreasonably withheld or delayed
         sell, assign or transfer all or any part of its rights under this
         Agreement and the Other Documents to one or more additional banks or
         financial institutions and one or more additional banks or financial
         institutions may commit to make Advances hereunder (each a "Purchasing
         Lender"), pursuant to a Commitment Transfer Supplement, executed by a
         Purchasing Lender, the transferor Lender, and Agent and delivered to
         Agent for recording provided no Purchasing Lender shall be sold an
         aggregate commitment of less than $5,000,000. Upon such execution,
         delivery, acceptance and recording, from and after the transfer
         effective date determined pursuant to such Commitment Transfer
         Supplement, (i) Purchasing Lender thereunder shall be a party hereto
         and, to the extent provided in such Commitment Transfer Supplement,
         have the rights and obligations of a Lender thereunder with a
         Commitment Percentage as set forth therein, and (ii) the transferor
         Lender thereunder shall, to the extent provided in such Commitment
         Transfer Supplement, be released from its obligations under this
         Agreement, the Commitment Transfer Supplement creating a novation for
         that purpose. Such Commitment Transfer Supplement shall be deemed to

                                      80
<PAGE>

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

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

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

         15.4.    APPLICATION OF PAYMENTS.
                  -----------------------

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

         15.5.    INDEMNITY.
                  ---------

         Each Borrower shall indemnify Agent and each Lender and their officers,
employees and agents from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses and
disbursements of any kind or nature whatsoever (including,

                                      81
<PAGE>

without limitation, fees and disbursements of counsel) which may be imposed on,
incurred by, or asserted against Agent or any Lender in any litigation,
proceeding or investigation instituted or conducted by any governmental agency
or instrumentality or any other Person with respect to any aspect of, or any
transaction contemplated by, or referred to in, or any matter related to, this
Agreement, whether or not Agent or any Lender is a party thereto, except to the
extent that any of the foregoing arises out of the willful misconduct or gross
(not mere) negligence of the party being indemnified.

         15.6.    NOTICE.
                  ------

         Any notice or request hereunder may be given to any Borrower or to

         The obligations of Borrowers under Sections 2.2(f), 3.7, 3.8, 3.9,
4.19(d), 14.7 and 15.5 shall survive termination of this Agreement and the Other
Documents and payment in full of the Obligations.

         15.8.    SEVERABILITY.
                  ------------

         If any part of this Agreement is contrary to, prohibited by, or deemed
invalid under applicable laws or regulations, such provision shall be
inapplicable and deemed omitted to the extent so contrary, prohibited or
invalid, but the remainder hereof shall not be invalidated thereby and shall be
given effect so far as possible.

         15.9.    EXPENSES.
                  --------

         Borrowers shall pay all costs and expenses including, without
limitation, reasonable attorneys' fees and disbursements incurred by Agent, any
Lender and Agent on behalf of the Lenders (a) in all efforts made to enforce
payment of any Obligation or effect collection of any Collateral, or (b) in
connection with the entering into, modification, amendment, administration and
enforcement of this Agreement or any consents or waivers hereunder and all
related agreements documents and instruments, or (c) in instituting,
maintaining, preserving, enforcing and foreclosing on Agent's security interest
in or Lien on any of the Collateral, whether through judicial proceedings or
otherwise, or (d) in defending or prosecuting any actions or proceedings arising
out of or relating to Agent's or any Lender's transactions with any Borrower, or

its rights and obligations under this Agreement and all related agreements.

         15.10.   INJUNCTIVE RELIEF.
                  -----------------

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

                                      84

         15.11.   CONSEQUENTIAL DAMAGES.
                  ---------------------

         Neither Agent nor Lenders nor any agent or attorney for any of them
shall be liable to any Borrower for consequential damages arising from any

XVI.     BORROWING AGENCY
         ----------------

         16.1.    BORROWING AGENCY PROVISIONS.
                  ---------------------------

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

                  (b)      The handling of this credit facility as a
co-borrowing facility with a borrowing agent in the manner set forth in this
Agreement is solely as an accommodation to Borrowers and at their request.
Neither Agent nor any Lender shall incur liability to Borrowers as a result
thereof. To induce Agent and Lenders to do so and in consideration thereof, each
Borrower hereby indemnifies Agent and each Lender and holds Agent and each
Lender harmless from and against any and all liabilities, expenses, losses,
damages and claims of damage or injury asserted against Agent or any Lender by
any Person arising from or incurred by reason of the handling of the financing
arrangements of Borrowers as provided herein, reliance by Agent or any Lender on
any request or instruction from Borrowing Agent or any other action taken by
Agent or any Lender with respect to this Section 15.1 except due to willful
misconduct or gross (not mere) negligence by the indemnified party.

                                      86
<PAGE>

                  (c)      All Obligations shall be joint and several
obligations of the Borrowers, and each Borrower shall make payment upon the
maturity of the Obligations by acceleration or otherwise, and such obligation
and liability on the part of each Borrower shall in no way be affected by any
extensions, renewals and forbearance granted by Agent or any Lender to any other
Borrower, failure of Agent or any Lender to give any Borrower notice of
borrowing or any other notice, any failure of Agent or any Lender to pursue or
preserve its rights against any Borrower, the release by Agent or any Lender of
any Collateral now or thereafter acquired from any Borrower, and such agreement
by each Borrower to pay upon any notice issued pursuant thereto is unconditional
and unaffected by prior recourse by Agent or any Lender to the other Borrowers
or any Collateral for such Borrower's Obligations or the lack thereof.

         16.2.    WAIVER OF SUBROGATION.
                  ---------------------

         Each Borrower expressly waives any and all rights of subrogation,
reimbursement, indemnity, exoneration, contribution of any other claim which
such Borrower may now or hereafter have against the other Borrowers or other
Person directly or contingently liable for the Obligations hereunder, or against
or with respect to the other Borrowers' property (including, without limitation,
any property which is Collateral for the Obligations), arising from the
existence or performance of this Agreement, until termination of this Agreement
and repayment in full of the Obligations.

         16.3.    OBLIGATIONS ABSOLUTE.
                  --------------------

         The liability of each Borrower to Agent and Lenders hereunder shall not
be affected or impaired by any of the following: (a) the validity or
enforceability of the Obligations or any part thereof, or of the Note or other
instrument or document evidencing all or any part of the Obligations, (b) the
absence of any attempt to collect the Obligations from a Borrower or any other
guarantor or other action to enforce the same, (c) any acceptance of collateral
security, guarantors, accommodation parties or sureties for any or all
Obligations; (d) one or more extensions or renewals of Obligations (whether or
not for longer than the original period) or any modification of the interest
rates, fees, maturities or principal amount of, or other contractual terms
applicable to any Obligations; (e) any waiver or indulgence granted to a
Borrower, any delay or lack of diligence in the enforcement of Obligations, or
any failure to institute proceedings, file a claim, give any required notices or
otherwise protect any Obligations; (f) any full or partial release of;
compromise or settlement with, or agreement not to sue a Borrower or any
guarantor or other person liable in respect of any Obligations; (g) any release,
surrender, cancellation or other discharge of any evidence of any of the
Obligations or the acceptance of any instrument in renewal or substitution
therefore; (h) any failure to obtain collateral security (including rights of
setoff) for any of the Obligations, or to obtain or maintain the proper or
sufficient creation and perfection thereof; or to establish the priority
thereof; or to preserve, protect, insure care for, exercise or enforce any
collateral security; (i) any collection, sale, lease or disposition of; or any
other foreclosure or enforcement of or realization on, any collateral security;
(j) any assignment, pledge or other transfer of any of the Obligations or any
evidence

                                      87
<PAGE>

thereof; (k) any manner, order or method of application of any payments or
credits upon any of the Obligations; (1) Agent's or any Lender's election, in
any case or proceedings under the Bankruptcy Code of the application of Section
111 (b)(2) thereof; (xiii) any borrowing or grant of a Lien by a Borrower as
debtor in possession under Section 364 of the Bankruptcy Code and (m) the
disallowance under the Bankruptcy Code of all or any portion of Agent's or such
Lender's claim for repayment of the Obligations. Each Borrower hereby waives any
and all legal and equitable defenses and discharges available to a surety
guarantor, or accommodation co-obligor.

         Each Borrower hereby assumes responsibility for keeping itself informed
of the financial condition of the other Borrower, and any and all endorsers and
other guarantors of any agreement, instrument or document evidencing or security
all or any part of the Obligations and of all other circumstances bearing upon
the risk of nonpayment of the Obligations or any part thereof that diligent
inquiry would reveal, and each Borrower hereby agrees that neither Agent nor any
Lender shall have any duty to advise such Borrower of information regarding such
condition or any such circumstances. Each Borrower hereby acknowledges
familiarity with the other Borrower's financial condition and has not relied on
any statements by Agent or Lenders in obtaining such information. In the event
Agent or any Lender, in its sole discretion, undertakes at any time or from time
to time to provide any such information to a Borrower, it shall not be under any
obligation (i) to undertake any investigation with respect thereto, (ii) to
disclose any information which, pursuant to accepted or reasonable credit
practices, Agent wishes to maintain confidential or (iii) to make any other or
future disclosures of such information, or any other information, to such
Borrower.

         16.4.    WAIVER.
                  ------

         UPON THE OCCURRENCE OF AN EVENT OF DEFAULT, AGENT OR ANY LENDER MAY, AT
ITS SOLE ELECTION, PROCEED DIRECTLY WITHOUT NOTICE, AGAINST A BORROWER TO
COLLECT AND RECOVER ALL OR ANY PART OF THE OBLIGATIONS WITHOUT FIRST PROCEEDING
AGAINST THE OTHER BORROWER, ANY OTHER GUARANTOR, OR ANY COLLATERAL FOR THE
OBLIGATIONS.

         EACH BORROWER ALSO WAIVES ALL SETOFFS AND COUNTERCLAIMS AND ALL
PRESENTMENTS, DEMANDS FOR PERFORMANCE, NOTICES OF NONPERFORMANCE, PROTESTS,
NOTICES OF PROTEST, NOTICES OF DISHONOR, AND NOTICES OF ACCEPTANCE OF THIS
GUARANTY. EACH BORROWER FURTHER WAIVES ALL NOTICES OF THE EXISTENCE, CREATION OR
INCURRING OF NEW OR ADDITIONAL INDEBTEDNESS, ARISING EITHER FROM ADDITIONAL
LOANS EXTENDED TO THE OTHER BORROWERS OR OTHERWISE, AND EXCEPT FOR NOTICES
EXPRESSLY REQUIRED HEREUNDER, ALSO WAIVES ALL NOTICES THAT THE PRINCIPAL AMOUNT,
OR ANY PORTION THEREOF, OR ANY INTEREST ON ANY AGREEMENT, INSTRUMENT OR DOCUMENT
EVIDENCING OR SECURING ALL OR ANY PART OF THE OBLIGATIONS IS DUE, NOTICES OF ANY
AND ALL PROCEEDINGS TO COLLECT FROM THE MAKER, ANY ENDORSER OR ANY OTHER
GUARANTOR OF ALL OR ANY PART OF THE OBLIGATIONS, OR FROM ANY OTHER

                                      88
<PAGE>

PERSON, AND TO THE EXTENT PERMITTED BY LAW, NOTICES OF EXCHANGE, SALE, SURRENDER
OR OTHER HANDLING OF ANY COLLATERAL GIVEN TO AGENT AND LENDERS TO SECURE PAYMENT
OF THE OBLIGATIONS.

         16.5.    RECOVERY.
                  --------

         Each Borrower agrees that, to the extent that the other Borrower makes
a payment or payments to Agent or any Lender, or receives any proceeds of
Collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
to be repaid to such other Borrower, its estate, trustee, receiver or any other
party under any bankruptcy law, state or federal law, common law or equitable
cause, then to the extent of such payment or repayment, the Obligations or the
part thereof which has been paid, reduced or satisfied by such amount shall be
reinstated and continued in full force and effect as of the date such initial
payment, reduction or satisfaction occurred, and this cross guaranty shall
continue to be in existence and full force and effect, irrespective of whether
any evidence of the Obligations has been surrendered or canceled.

         16.6.    LIABILITY CUMULATIVE.
                  --------------------

         The liability of the Borrowers under this Section 16 is in addition to
and shall be cumulative with all liabilities of each Borrower to Agent and
Lenders under this Agreement and the Other Documents to which such Borrower is a
party or in respect of any Obligations or obligation of the other Borrowers,
without any limitation as to amount, unless the instrument or agreement
evidencing or creating such other liability specifically provides to the
contrary.

                                   BACKGROUND
                                   ----------

                  A.       On December 26, 2001, Borrowers, the financial
institutions which are now or which hereafter become a party hereto
(individually, a "Lender" and collectively, the "Lenders") and PNC, as agent
for Lenders (PNC in such capacity, the "Agent") entered into a certain Fourth
Amended and Restated Revolving Credit and Security Agreement (as amended,
modified, renewed, extended, replaced or substituted from time to time, the
"Loan Agreement") to reflect certain financing arrangements between the parties
thereto. The Agreement and all other documents executed in connection therewith
are collectively referred to as the "Existing Financing Agreements." All
capitalized terms not otherwise defined herein shall have the meaning ascribed
thereto in the Agreement. In the case of a direct conflict between the
provisions of the Agreement and the provisions of this Amendment, the
provisions hereof shall prevail.

                  B.       The Borrowers have requested and the Agent has
agreed to modify certain definitions, terms and conditions contained in the
Loan Agreement to facilitate the execution of a Commitment Transfer Supplement
by and between Lenders and Fleet Capital Corp.

                  C.       The parties have agreed, subject to the terms and
conditions of this Amendment, to modify and amend the Existing Financing
Agreements.

         NOW THEREFORE, with the foregoing background hereinafter deemed
incorporated by reference herein and made part hereof, the parties hereto,
intending to be legally bound, promise and agree as follows:

         1.       Section I of the Loan Agreement shall be amended by deleting
the definition of "Required Lenders" in its entirety and replacing it with the
following:

                           "'Required Lenders' shall mean (i) if there are no
                             ----------------
                  more than two Lenders, Lenders holding one hundred percent
                  (100%) of the Advances or if no Advances are outstanding, one
                  hundred percent (100%) of the Commitment Percentages; and (ii)
                  if there are more than two Lenders, Lenders holding fifty one
                  percent
<PAGE>

                  (51%) of the Advances or if no Advances are outstanding, fifty
                  one percent (51%) of the Commitment Percentages."

         2.       Section VI of the Loan Agreement shall be amended as follows:

                  (a)      Section 6.5 shall be deleted in its entirety and
                           replaced as follows:

                  "6.5     FIXED CHARGE COVERAGE RATIO FOR RADNOR ON A
                           -------------------------------------------
                  CONSOLIDATED BASIS.
                  ------------------

                           Cause to be maintained a Fixed Charge Coverage Ratio
                  for Radnor on Consolidated Basis to be equal to or greater
                  than 1.00 to 1.00 as at the end of each fiscal quarter for the
                  most recent four fiscal quarters then ended, beginning at the
                  end of the first quarter of 2002."

                  (b)      Section 6.7 shall be deleted in its entirety and
                           replaced as follows:

                  "6.7     SENIOR NOTES AND SECOND SENIOR NOTES.
                           ------------------------------------

                           Shall, on or before September 1, 2003 deliver to
                  Agent evidence that Radnor has either (a) caused the holders
                  of the Senior Notes and the Second Senior Notes to extend the
                  maturity date of the Senior Notes and Second Senior Notes or
                  (b) refinanced, on terms no less favorable to Lenders, the
                  Senior Notes and Second Senior Notes pursuant to satisfactory
                  agreements as reasonably determined by Required Lenders in
                  their sole and absolute direction."

                  (c)      A new Section 6.12 shall be added to the Loan
                           Agreement as follows:

                  "6.12    ASSETS AND CONSOLIDATED EBITDA MAINTENANCE.
                           ------------------------------------------

                           The consolidated tangible assets (calculated in
                  accordance with GAAP) of the Borrowers will, at all times,
                  represent at least 85% of the consolidated tangible assets of
                  Radnor's Subsidiaries operating in the United States on a
                  consolidated basis and the consolidated EBITDA of the
                  Borrowers will, at all times, represent at least 85% of the
                  consolidated EBITDA of Radnor's Subsidiaries operating in the
                  United States on a consolidated basis. If, at any time, the
                  Borrowers fail to maintain such values, the Borrowers will
                  cause such of their Subsidiaries, as are mutually agreeable to
                  the Agent and Radnor, to join into this Agreement as
                  additional borrowers, and to execute such documents, including
                  the form of Joinder Agreement attached hereto as Exhibit
                  7.12-A as the Agent requires such that the conditions of this
                  covenant shall be satisfied."

         3.       Section XIV of the Loan Agreement shall be amended by deleting
Section 14.9 in its entirety and replacing it as follows:

                  "14.9    DELIVERY OF DOCUMENTS.
                           ---------------------

                           To the extent Agent receives material financial
                  documents or information from any Borrower that is not
                  otherwise required to be delivered to Lenders by Borrower
                  pursuant to this Agreement (i.e. borrowing base certificates,
                  notices of borrowing, etc.), Agent will promptly furnish such
                  documents and information to Lenders."

         4.       Section XV of the Loan Agreement shall be amended as follows:

                  (a)      Section 15.2(b)(vi) shall be deleted in its entirety
                           and replaced as follows:

                           "(vi) permit (a) the outstanding Revolving Advances
                  to exceed 110% of the Formula Account ("Allowable Excess
                  Advance") or (b) any Allowable Excess Advance to be
                  outstanding for more than (10) consecutive Business Days, or
                  (c) an Allowable Excess Advance to be outstanding on more than
                  three occasions during any given one (1) year period, or (d)
                  any Revolving Advances to be made at any time if after giving
                  effect thereto any of the requirements set forth in clauses
                  (a), (b) and (c) above would not be satisfied."

                  (b) In Section 15.2, the first full paragraph on page 79 of
the Loan Agreement beginning "Notwithstanding (a)" shall be deleted in its
entirety and replaced as follows:

                           "Notwithstanding (a) the existence of a Default or an
                  Event of Default, (b) that any of the other applicable
                  conditions precedent set forth in Section 8.2 hereof have not
                  been satisfied or (c) any other provision of this Loan
                  Agreement, Agent may at its discretion and without the consent
                  of the Required Lenders, voluntarily permit the outstanding
                  Revolving Advances at any time to exceed the Formula Amount by
                  up to one hundred and ten percent (110%) of the Formula Amount
                  for up to ten (10) consecutive Business Days, but no more than
                  three (3) times in any given one (1) year period. For purposes
                  of the preceding sentence, the discretion granted to Agent
                  hereunder shall not preclude involuntary overadvances that may
                  result from time to time due to the fact that the Formula
                  Amount was unintentionally exceeded for any reason, including,
                  but not limited to, Collateral previously deemed to be either
                  "Eligible Receivables" or "Eligible

                                      Page -3-

                  Inventory", as applicable, becomes ineligible, collections of
                  Receivables applied to reduce outstanding Revolving Advances
                  are thereafter returned for insufficient funds or overadvances
                  are made to protect or preserve the Collateral. In the event
                  Agent involuntarily permits the outstanding Revolving Advances
                  to exceed the Formula Amount by more than ten percent (10%),
                  Agent shall use its efforts to have Borrowers decrease such
                  excess in as expeditious a manner as is practicable under the
                  circumstances and not inconsistent with the reason for such
                  excess.  Revolving Advances made after Agent has determined
                  the existence of involuntary overadvances shall be deemed to
                  be involuntary overadvances and shall be decreased in
                  accordance with the preceding sentence."

                  (c)      The notice provisions in Section 15.6(A) of the Loan
Agreement shall be amended by adding:
