                                  BACKGROUND

          A.  The parties hereto have entered into the Third Amended and
Restated Receivables Purchase Agreement (as amended, amended and restated,
supplemented or otherwise modified from time to time, the "Market Street
Purchase Agreement") dated as of November 15, 2001 pursuant to which, among

the Pool Receivables and Related Assets;

          B.  The parties hereto wish to amend the Market Street Purchase
Agreement as set forth below;

          NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

          SECTION 1.  Definitions.  Except as otherwise defined herein,
capitalized terms used in this Amendment have the meanings set forth in the
Market Street Purchase Agreement.

          SECTION 2.  Amendments.  Section 1.01 of the Market Street Purchase
Agreement is amended by:

          (a)  amending the first proviso in its entirety to read as follows:

          "provided that no Purchase shall be made by Purchaser if, after
          giving effect thereto, either (a) the then Purchaser's Total
          Investment would exceed $45,000,000 (the `Purchase Limit'), or (b)
          the Asset Interest, expressed as a percentage of Net Pool Balance,
          would exceed 100% (the `Allocation Limit')"; and

          (b)  inserting the following new sentence at the end thereof:

              "The Purchase Limit shall be decreased (i) by $2,500,000
          concurrently with the sale, transfer or other disposal of all or
          substantially all of the Grinding Wheels division of Marketing Co.
          and (ii) by $2,500,000 concurrently with the sale, transfer or other
          disposal of all or substantially all of the membership interests
          and/or assets of Talbot Holdings, LLC."



          SECTION 3.  Representations and Warranties.  Each Seller Party
represents and warrants with respect to such Seller Party as follows:

              (a) this Amendment has been duly authorized, executed and
         delivered on its behalf, and the Market Street Purchase Agreement, as
         so amended, and each of the other Transaction Documents to which any
         Seller Party is a party constitutes such Seller Party's legal, valid
         and binding obligation, enforceable against it in accordance with the
         terms hereof or thereof except as enforceability may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium,
         fraudulent transfer or other similar laws affecting the enforcement
         of creditors' rights generally and by general equitable principles
         (whether considered in a proceeding in equity or at law);

              (b) the representations and warranties made by such Seller
         Party in the Transaction Documents are true and correct as of the
         date hereof (except to the extent that such representations and
         warranties expressly relate to an earlier date, in which case they
         were true as of such earlier date); and

              (c) after giving effect to this Amendment, no Liquidation
         Event (or Unmatured Liquidation Event) shall exist as of the
         Amendment Effective Date.

          SECTION 4.  Closing Conditions.  This Amendment shall become effective
on the first date (the "Amendment Effective Date") on which the Administrator
shall have received:

          (a)  this Amendment duly executed by the parties hereto and thereto;
and

          (b)  such other agreements, instruments, certificates, opinions and
other documents as the Administrator may reasonably request.

          SECTION 5.  Miscellaneous.  (a) THIS AMENDMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK,
WITHOUT REFERENCE TO CONFLICT OF LAW PRINCIPLES.

          (b)  This Amendment may be executed in any number of counterparts and
by the different parties hereto in separate counterparts, each of which when
so executed shall be deemed to be an original, and all of which together shall
constitute one and the same agreement.

          (c)  Any reference to the Market Street Purchase Agreement contained
in any notice, request, certificate or other document executed concurrently
herewith or after the date hereof shall be deemed to be a reference to the
Market Street Purchase Agreement as amended hereby. Except as expressly
modified hereby, the Transaction Documents hereby are ratified and confirmed
by the parties hereto, and remain in full force and effect.



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