                  For purposes only of applying the Inventory Loan Limit, Agent

                  Credit for the purpose of purchasing Eligible Inventory as
                  Loans to the extent Agent is in effect basing the issuance of
                  the Letter of Credit on the Value of the Eligible Inventory
                  being purchased with such Letter of Credit. In determining the
                  actual amounts of such Letter of Credit to be so treated for
                  purposes of the Inventory Loan Limit, the outstanding Loans
                  and Reserves shall be attributed first to any components of
                  the lending formulas set forth above that are not subject to
                  such sublimit, before being attributed to the components of
                  the lending formulas subject to such sublimit. The amounts of
                  Eligible Inventory shall, at Agent's option, be determined
                  based on the lesser of the amount of Inventory set forth in
                  the general ledger of Borrowers or the perpetual inventory
                  record maintained by Borrowers. Notwithstanding anything to
                  the contrary contained herein, the maximum outstanding amount
                  of Revolving Loans made under Section 2.1 hereof against
                  Eligible Foreign Non-LC Accounts (as defined in Section 1.42
                  hereof) shall not exceed $10,000,000 at any given time.
                  Notwithstanding anything to the contrary contained herein, the

                  Materials, Category 2 Raw Materials, Category 1
                  Work-in-Process and Category 2 Work-in-Process shall be
                  subject to reduction by Agent on the basis of any appraisals
                  of such Inventory, as applicable, provided to or conducted by
                  or on behalf of Agent in accordance with the terms hereof.

                  Notwithstanding anything herein to the contrary, a single
                  advance rate in respect of all raw materials constituting
                  Eligible Inventory equal to the lesser of twenty (20%) percent
                  multiplied by the Value of the Eligible Inventory consisting
                  of raw materials or ninety (90%) percent of the Net Recovery
                  Percentage multiplied by the Value of such Inventory shall be
                  substituted for clauses 1.15(a)(B)(2), (3) and (4) and shall
                  be applicable unless and until the Borrowers shall, at any
                  time and from time to time, elect to segregate and separately
                  identify and report to Agent the respective types of raw
                  materials by category. Effective upon the date of the
                  reporting of the next regularly scheduled borrowing base
                  hereunder, following not less than five (5) Business Days'
                  written notification of such election by Borrowers to Agent,
                  the multiple advance rates in respect of categories of raw
                  materials set forth above shall apply. Borrowers may at any
                  time upon five (5) Business Days' prior written notice to
                  Agent revoke their election to segregate and separately
                  identify and report to Agent the respective types of raw
                  materials by category, at which time the single advance rate
                  in respect of all raw materials



                  constituting Eligible Inventory shall apply effective upon the
                  date of the reporting of the next regularly scheduled
                  borrowing base hereunder."

                  entirety and the following substituted therefor:

                        "Cash Dominion Event" shall mean that (a) a Default or
                        Event of Default shall exist or have occurred and be
                        continuing or (b) Excess Availability shall be less than
                        $15,000,000 for any three (3) consecutive days.

            (d)   Section 1.23 of the Loan Agreement is hereby deleted in its
                  entirety and the following substituted therefor:

                        "Cash Dominion Termination" shall mean, after the
                        occurrence of a Cash Dominion Event, that Excess
                        Availability is equal to or greater than $15,000,000 for
                        each of ninety (90) consecutive days and no Default or
                        Event of Default shall exist or have occurred and be
                        continuing at any time during such period of ninety (90)
                        consecutive days and including the last day of such
                        period."

            (e)   Section 1.41 of the Loan Agreement is hereby amended by
                  deleting the word "plus" at the end of clause (d) thereof,
                  substituting a period "." therefor and deleting clause (e) of
                  such definition in its entirety.

regarding or relating to the Loan Agreement or the other Financing Agreements.
Agent, the Lenders, Borrowers and Guarantors desire to resolve each and every
one of such Claims in conjunction with the execution of this Amendment and thus
each Borrower and Guarantor makes the release contained in this Section 7. In
consideration of Agent's and Lenders' entering into this Amendment and agreeing
to the substantial concessions as set forth herein, each Borrower and Guarantor
hereby fully and unconditionally releases and forever discharges Agent and each
Lender and their respective directors, officers, employees, subsidiaries,
branches, affiliates, attorneys, agents, representatives, successors and assigns
and all persons, firms, corporations and organizations acting on any of their
behalves (collectively, the "Released Parties"), of and from any and all claims,
allegations, causes of action, costs or demands and liabilities, of whatever
kind or nature, from the beginning of the world up to and including the date on
which this Amendment is executed, whether known or unknown, liquidated or
unliquidated, fixed or contingent, asserted or unasserted, foreseen or
unforeseen, matured or unmatured, suspected or unsuspected, anticipated or
unanticipated, which such Borrower or Guarantor has, had, claims to have had or
hereafter claims to have against the Released Parties by reason of any act or
omission on the part of the Released Parties, or any of them, occurring prior to
the date on which this Amendment is executed, in any way affecting, concerning
or arising out of or founded upon this Amendment, the Loan Agreement or any of
the other Financing Agreements, including all



such loss or damage of any kind heretofore sustained or that may arise as a
consequence of the dealings among the parties arising from, in connection with
or related to the administration or enforcement of the Loans, the Obligations,
the Loan Agreement or any of the other Financing Agreements (collectively, all
of the foregoing are the "Claims"). Each Borrower and Guarantor represents and
warrants that it has no knowledge of any claim by it against the Released
Parties or of any facts or acts or omissions of the Released Parties which on
the date hereof would be the basis of a claim by such Borrower or Guarantor
against the Released Parties which is not released hereby. Each Borrower and
Guarantor represents and warrants that the foregoing constitutes a full and
complete release of all Claims.

      8. Effect of this Amendment. This Amendment and the instruments and
agreements delivered pursuant hereto constitute the entire agreement of the
parties with respect to the subject matter hereof and thereof, and supersede all
prior oral or written communications, memoranda, proposals, negotiations,
discussions, term sheets and commitments with respect to the subject matter
hereof and thereof. Except as expressly provided herein, no other changes,
modifications or consents to the Financing Agreements are intended or implied,
and in all other respects the Financing Agreements are hereby specifically
ratified, restated and confirmed by all parties hereto as of the effective date
hereof. To the extent that any provision of the Loan Agreement or any of the
other Financing Agreements is inconsistent with the provisions of this
Amendment, the provisions of this Amendment shall control.

      9. Further Assurances. Each Borrower and Guarantor shall execute and
deliver such additional documents and take such additional action as may be

Amendment.

      10. Governing Law. The rights and obligations hereunder of each of the
parties hereto shall be governed by and interpreted and determined in accordance
with the internal laws of the State of New York but excluding any principles of
conflicts of law or other rule of law that would cause the application of the
law of any jurisdiction other than the laws of the State of New York.

      11. Binding Effect. This Amendment shall be binding upon and inure to the
benefit of each of the parties hereto and their respective successors and
assigns.

      12. Counterparts. This Amendment may be executed in any number of
counterparts, but all of such counterparts shall together constitute but one and
the same agreement. In making proof of this Amendment, it shall not be necessary
to produce or account for more than one counterpart thereof signed by each of
the parties hereto. Delivery of an executed counterpart of this Amendment by
telecopier or other method of electronic transmission shall have the same force
and effect as delivery of an original executed counterpart of this Amendment.
Any party delivering an executed counterpart of this Amendment by telecopier or
other method of electronic transmission also shall deliver an original executed
counterpart of this Amendment, but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Amendment as to such party or any other party.



      IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
duly executed and delivered by their authorized officers as of the day and year
first above written.
