and among PARKOHIO INDUSTRIES, INC., an Ohio corporation ("Borrower"), SOCIETY

         WHEREAS, Borrower, Agent and the Banks are parties to a certain credit

         WHEREAS, each term used herein shall be defined in accordance with the

         NOW, THEREFORE, in consideration of the premises and of the mutual

   2

         3. Borrower hereby represents and warrants to the Agent and the Banks
that (a) Borrower has the legal power and authority to execute and deliver this
Third Amendment Agreement; (b) officials executing this Third Amendment
Agreement 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 Possible Default
exists under the Credit Agreement, nor will any occur immediately after the
execution and delivery of the Third Amendment Agreement or by the performance or
observance of any provision hereof; (e) neither Borrower nor any Subsidiary has

any Subsidiary's obligations or liabilities under the Credit Agreement or any
Related Writing, and Borrower and each Subsidiary hereby waives and releases the
Agent and each of the Banks from any and all such claims, offsets, defenses and
counterclaims of which Borrower and any Subsidiary 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,
and (f) this Third Amendment Agreement constitutes a valid and binding
obligation of Borrower in every respect, enforceable in accordance with its
terms.

         4. Each reference that is made in the Credit Agreement or any other
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.

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.

         6. The rights and obligations of all parties hereto shall be governed
by the laws of the State of Ohio.
