to read in its entirety as follows:

                  2.1.3 Letter of Credit Commitment; Reimbursement Obligations.
         (a) Upon written request from the Company, CFC (on behalf of all the
         Lenders) will issue to the Issuer, guaranties, in such form as is
         reasonably satisfactory to CFC, the Issuer and the Company (each
         herein, together with any extensions or renewals thereof, or guaranties
         issued by CFC in substitution therefor from time to time, called an "LC
         Guaranty"), of reimbursement obligations of the Company arising under
         reimbursement agreements in such form as is reasonably satisfactory to
         CFC, the Issuer and the Company (herein, collectively called the "LC
         Reimbursement Agreements" and individually called an "LC Reimbursement
         Agreement") executed by the Company in connection with Letters of
         Credit; provided, however, that CFC shall not issue any LC Guaranty if,
         after giving effect to such issuance, (i) the aggregate Stated Amount
         of all Letters of Credit shall exceed $10,000,000 or (ii) the Revolving
         Outstandings exceed the Revolving Commitment Amount. Each such request
         by the Company for an LC Guaranty shall specify the Stated Amount of
         the proposed underlying Letter of Credit, the beneficiary thereof, the
         proposed date of issuance of such Letter of Credit and such other
         matters as CFC may reasonably require.

                  (b) Upon CFC making any payment under any LC Guaranty, if the
         Company has not reimbursed CFC in full for such payment or disbursement
         by 11:00 A.M., Detroit time, on the date of such payment, or if any
         reimbursement received by CFC from the Company is or must be returned
         or rescinded upon or during any bankruptcy or reorganization of the
         Company or otherwise, each other Lender shall be obligated to pay to
         CFC its Pro Rata Share of such payment (but no such


                                      -2-

   3

         payment shall diminish the obligation of the Company under Section
         2.1.3(c)). Each Lender irrevocably and unconditionally agrees to so pay
         to CFC in immediately available funds the amount of such Lender's Pro
         Rata Share of such payment. If and to the extent any Lender shall not
         have made such amount available to CFC by 2:00 P.M., Detroit time, on
         the Business Day on which such Lender receives notice from CFC of such
         payment (it being understood that any such notice received after noon,
         Detroit time, on any Business Day shall be deemed to have been received
         on the next following Business Day), such Lender agrees to pay interest
         on such amount to CFC forthwith on demand, for each day from the date
         such amount was to have been delivered to CFC to the date such amount
         is paid, at a rate per annum equal to (i) for the first three days
         after demand, the Federal Funds Rate from time to time in effect and
         (ii) thereafter, the Prime Rate from time to time in effect. Any
         Lender's failure to make available to CFC its Pro Rata Share of any
         such payment shall not relieve any other Lender of its obligation
         hereunder to make available to CFC such other Lender's Pro Rata Share
         of such payment, but no Lender shall be responsible for the failure of
         any other Lender to make available to CFC such other Lender's Pro Rata
         Share of any such payment.

                  (c) Notwithstanding any provision herein to the contrary,
         immediately upon the Issuer's presentation of any demand for payment
         under an LC Guaranty, the Company shall be obligated to reimburse CFC
         for such demand, on the date on which CFC honors such demand, in
         immediately available funds equal to the amount of such honored demand
         (such obligations being referred to herein as "Reimbursement
         Obligations"). If all or any part of such demand is not paid by the
         Company when due, such unpaid amount shall bear interest for each day
         during the period from the day of such demand until it shall be paid in
         full at a rate equal to the Prime Rate from time to time in effect (but
         not less than the Prime Rate in effect on the date on which CFC shall
         have honored such demand) plus two percent (2%) per annum; such
         interest shall be payable on demand.

                  (d) The obligation of the Company to reimburse CFC for demands
         made under the LC Guaranties shall be unconditional and irrevocable and
         shall be enforced strictly in accordance with the terms of this
         Agreement under all circumstances, including, without limitation, the
         following:

                  (A) lack of validity or enforceability of the appropriate LC
         Guaranty or Letter of Credit;

                  (B) the existence of any claim, set-off, defense or other
         right which the Company may have at any time against CFC or the Issuer,
         Lender or any other Person, whether in connection with this Agreement,
         the transactions contemplated herein or any unrelated transaction
         (including any underlying transaction between the Company and the
         beneficiary under a Letter of Credit);

                  (D) any draft, demand, certificate or any other document
         presented under an LC Guaranty or a Letter of Credit proving to be
         forged, fraudulent, invalid or insufficient in any respect or any
         statement therein being untrue or inaccurate in any respect;

   4

                  (E) payment by CFC under an LC Guaranty against a demand which
         does not comply with the terms of such LC Guaranty, provided that such
         payment does not constitute gross negligence or willful misconduct of
         CFC;

                  (F) any adverse change in the condition (financial or
         otherwise) of the Company;

                  (G) any breach of this Agreement by the Company, the Agent,
         CFC or any other Lender;

                  (H)      any other circumstance or happening whatsoever; or

                  (I) the fact that an Event of Default or an Unmatured Event of
         Default shall have occurred and be continuing.

                  (d) As between the Company, the Agent and the Lenders, the
         Company assumes all risks of the acts and omissions of, or misuse of
         any LC Guaranty by, the Issuer or any beneficiary of a Letter of
         Credit. Without limiting the foregoing, neither the Agent, CFC nor any
         other Lender shall be responsible for: (i) the form, validity,
         sufficiency, accuracy, genuineness or legal effect of any document
         submitted by any Person in connection with the application for and
         issuance of a LC Guaranty or Letter of Credit, even if such document is
         proven to be in any respect invalid, insufficient, inaccurate,
         fraudulent or forged; (ii) the validity or sufficiency of any
         instrument transferring or assigning or purporting to transfer or
         assign a LC Guaranty or Letter of Credit or the rights or benefits
         thereunder or proceeds thereof, in whole or in part, which may prove to
         be invalid or ineffective for any reason; (iii) the failure of the
         beneficiary of a Letter of Credit to comply fully with conditions
         required in order to draw thereupon, or the failure of the Issuer to
         comply fully with conditions required in order to demand under a LC
         Guaranty; (iv) errors, omissions, interruptions or delays in
         transmission or delivery of any messages, by mail, cable, telegraph,
         facsimile, telex or otherwise, whether or not they be in cipher; (v)
         errors in interpretation of technical terms; (vi) any loss or delay in
         the transmission or otherwise of any document required in order to make
         a drawing under a Letter of Credit or a demand under a LC Guaranty or
         of the proceeds of either thereof; (vii) the misapplication by the
         Issuer of the proceeds of any demand under a LC Guaranty; and (viii)
         any consequence arising from causes beyond the control of the Agent,
         CFC or any other Lender. None of the above shall affect, impair or
         prevent the vesting of any of the rights or powers hereunder of the
         Agent, CFC or any other Lender.

         1.4 Section 2.3 of the Credit Agreement shall be amended and restated
to read in its entirety as follows: "[Intentionally left blank]."
