day of February, 2003, by and among THE TIMKEN COMPANY, an Ohio corporation
("Borrower"), the financial institutions listed on Schedule 1 to the Credit
Agreement, as hereinafter defined (collectively, the "Banks" and, individually,
each a "Bank"), and KEYBANK NATIONAL ASSOCIATION, as administrative agent
("Agent"):

     WHEREAS, Borrower, Agent and the Banks are parties to that certain Credit
Agreement, dated as of July 10, 1998, that provides, among other things, for
loans aggregating Three Hundred Million Dollars ($300,000,000), all upon
certain terms and conditions (as amended and as the same may from time to time
be further amended, restated or otherwise modified, the "Credit Agreement");

     WHEREAS, Borrower, Agent and the Banks desire to amend the Credit
Agreement to modify certain provisions thereof; and

     WHEREAS, each capitalized term used herein and defined in the Credit
Agreement, but not otherwise defined herein, shall have the meaning given such
term in the Credit Agreement;

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein and for other valuable considerations, Borrower, Agent and the
Banks agree as follows:

     1.   Amendment to Reduction of Commitment Provision.  Section 2.5(c) of
the Credit Agreement is hereby amended to delete the words "not fewer than five
(5) Business Days' notice" therefrom and to insert in place thereof the words
"not fewer than one (1) Business Day's notice".

     2.   Closing Item.  Concurrently with the execution of this Amendment,
Borrower shall pay all legal fees and expenses of Agent in connection with this
Amendment.

     3.   Representations and Warranties.  Borrower hereby represents and
warrants to Agent and the Banks that (a) Borrower has the legal power and
authority to execute and deliver this Amendment; (b) the officers executing
this Amendment have been duly authorized to execute and deliver the same and
bind Borrower with respect to the provisions hereof; (c) the execution and
delivery hereof by Borrower and the performance and observance by Borrower of
the provisions hereof do not violate or conflict with the organizational
agreements of Borrower or any law applicable to Borrower or result in a breach
of any provision of or constitute a default under any other agreement,
instrument or document binding upon or enforceable against Borrower; (d) no
Default or Event of Default exists under the Credit Agreement, nor will any
occur immediately after the execution and delivery of this Amendment or by the
performance or observance of any provision hereof; (e) Borrower is not aware
of any claim or offset against, or defense or counterclaim to, Borrower's
obligations or liabilities under the Credit Agreement or any Related Writing;


and (f) this Amendment constitutes a valid and binding obligation of Borrower
in every respect, enforceable in accordance with its terms.

     4.   Waiver.  Borrower hereby waives and releases Agent and each of the
Banks and their respective directors, officers, employees, attorneys,
affiliates and subsidiaries from any and all claims, offsets, defenses and
counterclaims of which Borrower is aware, such waiver and release being with
full knowledge and understanding of the circumstances and effect thereof and
after having consulted legal counsel with respect thereto.

     5.   References to Credit Agreement.  Each reference that is made in the
Credit Agreement or any Related Writing shall hereafter be construed as a
reference to the Credit Agreement as amended hereby.  Except as herein
otherwise specifically provided, all provisions of the Credit Agreement shall
remain in full force and effect and be unaffected hereby.  This Amendment
is a Related Writing.

     6.   Counterparts.  This Amendment may be executed in any number of
counterparts, by different parties hereto in separate counterparts and by
facsimile signature, 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.

     7.   Governing Law.  The rights and obligations of all parties hereto
shall be governed by the laws of the State of Ohio, without regard to
principles of conflict of laws.
