---

| | A. | The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all of the business
and/or assets of the Company, by agreement in form and substance satisfactory to the Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent the Company would be required to perform if no such
succession had taken place. This Agreement will be binding upon and inure to the benefit of the Company and any successor to the Company, including without limitation any persons acquiring directly or indirectly all or substantially all of the
business and/or assets of the Company whether by purchase, merger, consolidation, reorganization or otherwise (and such successor will thereafter be deemed the Company for the purposes of this Agreement), but will not otherwise be
assignable, transferable or delegable by the Company.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

and/or legatees.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | This Agreement is personal in nature and neither of the parties hereto will, without the consent of the other, assign, transfer or delegate this Agreement or any rights or
obligations hereunder except as expressly provided in Sections 3(A) and (B) above. Without limiting the generality of the foregoing, the Executives right to receive the benefits hereunder is not assignable, transferable or delegable,
whether by pledge, creation of a security interest or otherwise, other than by a transfer by his will or by the laws of descent and distribution and, in the event of any attempted assignment or transfer contrary to this Section 3(C), the
Company has no liability to pay any amount so attempted to be assigned, transferred or delegated.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | D. | The Company and the Executive recognize that each party will have no adequate remedy at law for breach by the other of any of the agreements contained herein and, in the event of
any such breach, the Company and the Executive hereby agree and consent that the other shall be entitled to a decree of specific performance, mandamus or other appropriate remedy to enforce performance of this Agreement.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

4. For all purposes of this Agreement, all communications including without limitation notices, consents, requests or approvals, provided for herein must be in writing
and will be deemed to have been duly given when delivered or five business days after having been mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed to the Company (to the attention of the
Secretary of the Company) at its principal executive office and to the Executive at his principal residence, or to such other address as any party may have furnished to the other in writing and in accordance herewith, except that notices of change
of address shall be effective only upon receipt.

5. The validity, interpretation, construction and performance of this Agreement is governed by the laws
of the State of Ohio, without giving effect to the principles of conflict of laws of such State.

6. If any provision of this Agreement or the application
of any provision hereof to any person or circumstances is held invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any other person or

circumstances shall not be affected, and the provision so held to be invalid, unenforceable or otherwise illegal shall be reformed to the extent (and only to
the extent) necessary to make it enforceable, valid and legal.

7. No provision of this Agreement may be modified, waived or discharged unless such waiver,
modification or discharge is agreed to in writing signed by the Executive and the Company. No waiver by either party hereto at any time of any breach by the other party hereto or compliance with any condition or provision of this Agreement to be
performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, expressed or implied with respect to the
subject matter hereof have been made by either party which are not set forth expressly in this Agreement, other than the Employment Agreement between Executive and the Company dated July 24, 2000, as may be amended from time to time, which
remains in full force and effect.

8. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all
of which together will constitute one and the same agreement.

IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed and delivered as of the date first above written.
