        Section 3. Services. The Employee shall be the Chairman of the Board and

compensation:

                (a) A base salary of $192,000 per annum or if the term of the

                approved by the Company's Compensation Committee from time to
                time, payable in accordance with the Company's general policies
                for payment of compensation to its salaried personnel; provided

                the Company;

                (c) A cash bonus payable in the discretion of the Company's

<PAGE>   2
                upon such criteria as may be selected by such Committee,
                including without limitation the Employee's performance with
                respect to providing leadership to the Company's personnel,
                supervising the Company's operations, and enhancing value for
                the Company's stockholders; and

                (d) Formula Vesting Stock Options pursuant to the 1994 Executive
                Performance Stock Option Plan (the "Plan") for 1998 and, if the
                term of the Employee's employment is renewed, for each
                subsequent fiscal year of the Company (each "Performance Year")
                ending during each renewal term of the Employee's employment
                under this agreement with the number of Shares subject to the
                Formula Vesting Option and the Ceiling Amount (as such term is
                defined in the Plan) for determining accelerated vesting under
                the Plan being set forth for each Performance Year on the
                schedule attached to this agreement. Such amounts shall be set
                forth on the attached schedule on or about the anniversary date
                of this agreement for each year during which the term of the
                Employee's employment is renewed, and initialed by the Company
                and the Employee.

        The Company shall also provide disability insurance for the benefit of
the Employee and pay all premiums with respect thereto, which insurance shall
supplement the Company's current disability insurance benefits to the Employee.
The policy or policies for such disability insurance shall provide for benefits
in the amount of $6,000 per month for a maximum of five years, which benefits
shall commence 90 days after the date of the Employee's disability (as
determined under the terms of such policy).

        Section 6. Termination of Employment. The Employee's employment under
this agreement may be terminated:

                (a) By the Employee with or without cause upon giving 90 days
                advance written notice to the Company, provided that the
                Employee shall continue to perform all duties under this
                agreement until the earlier of:

                        (i) The expiration date of such 90-day period; or

                        (ii) Any earlier date which may be specified by the
                Company.

                (b) By the Company upon the occurrence of any one of the
                following events or any time thereafter:

                        (i) The Employee fails to fully perform and observe all
                obligations and conditions to be performed and observed by the
                Employee under this agreement, or under any other agreement
                between the Employee and the Company, and fails to correct such
                problem within 10 days after notice by the Board of Directors to
                do so or, if it is impossible to correct such problem within
                such 10 days, fails to commence the action necessary to correct
                such problem and continues diligently to pursue such action
                until the correction is complete; or

                        (ii) The Employee is under a long-term disability. For
                purposes of this agreement, the term "long-term disability"
                shall have the same meaning as long-term disability or other
                similar term used in any long-term or permanent disability
                policy provided by the Company and covering the Employee. In the
                event there is no long-term or permanent disability policy in
                effect covering the Employee, the term "long-term disability"
                shall mean that because of physical or mental incapacity, the
                Employee has not performed his duties under this agreement for
                60 days or longer and it is probable, in the opinion of a
                licensed physician selected by the Company, that the Employee
                will not
<PAGE>   3
                be able to engage actively in his employment by the Company for
                an additional period of 90 days or longer.

        Section 7. Employee's Capacity. The Employee represents and warrants to
the Company that he has the capacity and right to enter into this agreement and
perform all his duties under this agreement without any restriction whatsoever
by any other agreement, document, or otherwise.

        Section 8. Complete Agreement. This document contains the entire
agreement between the parties and supersedes any prior discussions,
negotiations, representations, or agreements between them relating to the
employment of the Employee. No additions or other changes to this agreement
shall be made or be binding on either party unless made in writing and signed by
each party to this agreement.

        Section 9. Notices. Any notice or other communication required or
desired to be given to any party under this agreement shall be in writing and
shall be deemed given:

                (a) In the case of the Employee, when delivered personally to
                the Employee or when deposited in the United States mail,
                first-class postage prepaid, addressed to the Employee at 340
                Tucker Drive, Worthington, Ohio 43085, or at any other address
                thereafter designated by the Employee in notice theretofore
                given to the Company; and

                (b) In the case of the Company, when deposited in the United
                States mail, first-class postage prepaid, addressed to the
                Company at 560 East Town Street, Columbus, Ohio 43215, or at any
                other address thereafter designated by the Company in notice
                theretofore given to the Employee.

        Section 10. Governing Law. All questions concerning the validity,
intention, or meaning of this agreement or relating to the rights and
obligations of the parties with respect to performance hereunder shall be
construed and resolved under the laws of Ohio.

        Section 11. Severability. The intention of the parties to this agreement
is to comply fully with all laws and public policies, and this agreement shall
be construed consistently with all laws and public policies to the extent
possible. If and to the extent that any court of competent jurisdiction is
unable to so construe part or all of any provision of this agreement, and holds
part or all of that provision to be invalid, such invalidity shall not affect
the validity of the balance of that provision or the remaining provisions of
this agreement, which shall remain in full force and effect.

        Section 12. Nonwaiver. No failure by any party to insist upon strict
compliance with any term of this agreement, to exercise any option, enforce any
right, or seek any remedy upon any default of any other party shall affect, or
constitute a waiver of, the first party's right to insist upon such strict
compliance, exercise that option, enforce that right, or seek that remedy with
respect to that default or any prior, contemporaneous, or subsequent default;
nor shall any custom or practice of the parties at variance with any provision
of this agreement affect, or constitute a waiver of, any party's right to demand
strict compliance with all provisions of this agreement.

        Section 13. Captions. The captions of the various sections of this
agreement are not part of the context of this agreement, but are only labels to
assist in locating those sections, and shall be ignored in construing this
agreement.

        Section 14. Successors. This agreement shall be binding upon, inure to
the benefit of, and be enforceable by and against the respective heirs, legal
representatives, successors, and assigns of each party to this agreement,
provided that neither party may assign any of its rights or obligations under
this agreement without the prior written consent of the other party.
