         during which Collateral Availability shall not be less than
         $9,000,000).

<PAGE>

         Section 2.        Effectiveness of Amendment. The provisions of SECTION
1 of this Amendment shall become effective as of the date hereof on the date

received (1) at least seven copies of this Amendment duly executed by the
Borrowers and the Required Lenders and (2) such other documents and instruments
as the Administrative Agent may reasonably request.

         Section 3.        Representations and Warranties. Each Borrower hereby
makes the following representations and warranties to the Administrative Agent
and the Lenders, which representations and warranties shall survive the delivery
of this Amendment and the making of additional Loans under the Loan Agreement as
amended hereby:

         (a)      Authorization of Agreements. Each Borrower has the right and
power, and has taken all necessary action to authorize it, to execute, deliver
and perform this Amendment and each other agreement contemplated hereby to which
it is a party in accordance with their respective terms. This Amendment and each
other agreement contemplated hereby to which it is a party has been duly
executed and delivered by the duly authorized officers of such Borrower and each
is, or each when executed and delivered in accordance with this Amendment will
be, a legal, valid and binding obligation of such Borrower, enforceable in
accordance with its terms.

         (b)      Compliance of Agreements with Laws. The execution, delivery
and performance of this Amendment and each other agreement contemplated hereby
to which such Borrower is a party in accordance with their respective terms do
not and will not, by the passage of time, the giving of notice or otherwise,

                  (i)      require any Governmental Approval or violate any
         Applicable Law relating to such Borrower or any of its Subsidiaries,

                  (ii)     conflict with, result in a breach of or constitute a
         default under the articles or certificate of incorporation or by-laws
         or any shareholders' agreement of such Borrower or any of its
         Subsidiaries, any material provisions of any indenture, agreement or
         other instrument to which such Borrower, any of its Subsidiaries or any
         of such Borrower's or such Subsidiaries' property may be bound or any
         Governmental Approval relating to such Borrower or any of its
         Subsidiaries, or

                  (iii)    result in or require the creation or imposition of
         any Lien upon or with respect to any property now owned or hereafter
         acquired by such Borrower other than the Security Interest.

         Section 4.        Effect of Amendment. From and after the Amendment
Effective Date, all references in the Loan Agreement and in any other Loan
Document to "this Agreement," "the Loan Agreement," "hereunder," "hereof" and
words of like import referring to the Loan Agreement, shall mean and be
references to the Loan Agreement as amended by this Amendment. Except as
expressly amended hereby, the Loan Agreement and all terms, conditions and
provisions thereof remain in full force and effect and are hereby ratified and
confirmed. The execution, delivery and effectiveness of this Amendment shall
not, except as expressly provided herein, operate as a waiver of any right,
power or remedy of the Administrative Agent and the

                                       2

Lenders under any of the Loan Documents, nor constitute a waiver of any
provision of any of the Loan Documents.

         Section 5.        Counterpart Execution; Governing Law.

         (a)      Execution in Counterparts. This Amendment may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which taken together shall constitute but one and the
same agreement. Delivery of an executed signature page of any party hereto by
facsimile transmission shall be as effective as delivery of a manually delivered
counterpart thereof.

         (b)      Governing Law. This Amendment shall be governed by and
construed in accordance with the laws of the State of New York without giving
effect to conflicts of law principles thereof.

         Section 2.        Effectiveness of Amendment. The provisions of SECTION
1 of this Amendment shall become effective as of the date hereof on the date
(the "Amendment Effective Date") on which the Administrative Agent shall have
received (1) a subordination agreement, executed and delivered by
Bridgestone/Firestone, Inc. (or an Affiliate thereof acceptable to the
Administrative Agent), with respect to the Vendor Lien in favor of

warranties made or deemed to be made under the Loan Agreement are true and
correct in all material respects on and as of the Amendment Effective Date, and
(ii) no Default or Event of Default exists (and the Administrative Agent shall
be satisfied as to the truth and accuracy thereof).

         Section 3.        Representations and Warranties. Each Borrower hereby
makes the following representations and warranties to the Administrative Agent
and the Lenders, which representations and warranties shall survive the delivery
of this Amendment and the making of additional Loans under the Loan Agreement as
amended hereby:

         (a)      Authorization of Agreements. Each Borrower has the right and
power, and has taken all necessary action to authorize it, to execute, deliver
and perform this Amendment and each other agreement contemplated hereby to which
it is a party in accordance with their respective terms. This Amendment and each
other agreement contemplated hereby to which it is a party has been duly
executed and delivered by the duly authorized officers of such Borrower and each
is, or each when executed and delivered in accordance with this Amendment will
be, a legal, valid and binding obligation of such Borrower, enforceable in
accordance with its terms.

         (b)      Compliance of Agreements with Laws. The execution, delivery
and performance of this Amendment and each other agreement contemplated hereby
to which such Borrower is a party in accordance with their respective terms do
not and will not, by the passage of time, the giving of notice or otherwise,

                  (i)      require any Governmental Approval or violate any
         Applicable Law relating to such Borrower or any of its Subsidiaries,

                  (ii)     conflict with, result in a breach of or constitute a
         default under the articles or certificate of incorporation or by-laws
         or any shareholders' agreement of such Borrower or any of its
         Subsidiaries, any material provisions of any indenture, agreement

                                       3

         or other instrument to which such Borrower, any of its Subsidiaries or
         any of such Borrower's or such Subsidiaries' property may be bound or
         any Governmental Approval relating to such Borrower or any of its
         Subsidiaries, or

                  (iii)    result in or require the creation or imposition of
         any Lien upon or with respect to any property now owned or hereafter
         acquired by such Borrower other than the Security Interest.

         Section 4.        Effect of Amendment. From and after the Amendment
Effective Date, all references in the Loan Agreement and in any other Loan
Document to "this Agreement," "the Loan Agreement," "hereunder," "hereof" and
words of like import referring to the Loan Agreement, shall mean and be
references to the Loan Agreement as amended by this Amendment. Except as
expressly amended hereby, the Loan Agreement and all terms, conditions and
provisions thereof remain in full force and effect and are hereby ratified and
confirmed. The execution, delivery and effectiveness of this Amendment shall
not, except as expressly provided herein, operate as a waiver of any right,
power or remedy of the Administrative Agent and the Lenders under any of the
Loan Documents, nor constitute a waiver of any provision of any of the Loan
Documents.

         Section 5.        Counterpart Execution; Governing Law.

         (a)      Execution in Counterparts. This Amendment may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which taken together shall constitute but one and the
same agreement. Delivery of an executed signature page of any party hereto by
facsimile transmission shall be as effective as delivery of a manually delivered
counterpart thereof.

         (b)      Governing Law. This Amendment shall be governed by and
construed in accordance with the laws of the State of New York without giving
effect to conflicts of law principles thereof.
