     best of his ability and using all his skills, Executive shall devote
     substantially all of his working time and efforts to the diligent and

     Agreement. However, Executive may devote a reasonable amount of his time to
     civic, community, or charitable activities.

 7.  TERMINATION OF EMPLOYMENT.

     (a)   DEATH. Executive's employment under this Agreement shall terminate
           upon Executive's death. If Executive's employment terminates pursuant

           Agreement effective upon 30 days written notice. If Executive's
           employment terminates pursuant to this Section 7(b), Executive or his
           legal representative shall be entitled to receive: the Base Salary up

     (c)   FOR CAUSE. Company also may terminate Executive's employment under
           this Agreement for cause. For purposes of this Agreement, "for cause"
           shall mean only (i) Executive's confession or conviction of theft,
           fraud, embezzlement, any felony, or any crime involving dishonesty
           with regard to the Company or any subsidiary or affiliate of the
           Company, (ii) Executive's excessive absenteeism without reasonable
           cause (other than because of a disability described in Section 7(b),
           (iii) habitual and material negligence by the Executive in the
           performance of Executive's duties and responsibilities as described
           in Section 1 (other than because of a disability described in Section
           7(b)) and Executive's failure to cure such negligence within 30 days
           after Executive's receipt of a written notice from the Chief
           Executive Officer setting forth in reasonable detail the particulars
           of such negligence, or (iv) material failure by Executive to comply
           with a lawful directive of the Chief Executive Officer (other than
           because of a disability described in Section 7(b)) and Executive's
           failure to cure such non-compliance within 10 days after Executive's
           receipt of a written notice from the Chief Executive Officer setting
           forth in reasonable detail the particulars of such non-compliance.
           Termination shall occur effective 30 days after "for cause" occurs
           under one of the above clauses (i) through (iv). If Executive's
           employment terminates pursuant to this Section 7(c), Executive shall
           be entitled to receive the Base Salary up through the effective date
           of termination and any benefits to which Executive is entitled
           pursuant to Sections 6(c) through 6(e) up through the effective date
           of termination, but shall not be entitled to any bonus for a
           completed calendar year which has not yet been paid.

     (d)   VOLUNTARY RESIGNATION. Executive may voluntarily resign from
           Company's employ at any time upon at least 30 days prior written
           notice of the effective date of such resignation. If Executive
           voluntarily resigns, Executive shall be entitled to receive the Base
           Salary up through the effective date of such resignation and any
           benefits to which Executive is entitled pursuant to Sections 6(c)
           through 6(e) up through the effective date of such resignation, but
           shall not be entitled to any bonus for a completed calendar year
           which has not yet been paid.

     (e)   CHANGE OF CONTROL. If Executive's employment under this Agreement is
           terminated by the Company other than for cause within three months
           following a Change of Control (as defined below), then Executive
           shall be entitled to continue to receive the Base Salary provided for
           in Section 5 for a period of 12 months after the effective date of
           such termination of employment on the Company's normal payroll dates
           during such period; provided, however, that if Executive accepts
           employment with another company during such salary continuation
           period, Executive shall immediately notify Company of such other
           employment and the payments pursuant to this Section 7(e) shall be
           reduced by the amount of the salary received by Executive from the
           other employer during such salary continuation period. For purposes
           of this Agreement, the term "Change of Control" shall mean (i) a
           consolidation or merger of the Company with or into any other person
           (including, without limitation, any corporation, partnership, limited
           liability company, or trust), other than a consolidation or merger in
           which the Company is the surviving entity and upon consummation of
           which the holders of voting securities of the Company immediately
           prior to such transaction continue to own, directly or indirectly, at
           least a majority of the voting securities of the Company, as the
           surviving entity, immediately following such transaction, (ii) a sale
           of all or substantially all of the assets of the

                                        3
<Page>

           Company, in a single transaction or series of related transactions,
           or (iii) a sale or other disposition of more than 50% of the voting
           stock of the Company (whether issued and outstanding, newly issued or
           from treasury, or any combination thereof), in a single transaction
           or series of related transactions.

     (f)   WITHOUT CAUSE. The Company may terminate Executive's employment under
           this Agreement without cause, which for purposes of this Agreement
           shall include any termination of Executive's employment by Company
           other than "for cause" as defined in Section 7(c) and other than
           because of disability pursuant to Section 7(b), upon no less than 30
           days prior written notice. Furthermore, if without Executive's
           written consent, Executive's base salary is decreased below the Base
           Salary level established by Section 5, or Executive's title,
           authority, role or level of responsibilities with the Company is
           decreased below that established by Section 1 (each of the foregoing,
           an "Adverse Change"), and Executive gives written notice of his
           termination of his employment with Company because of the Adverse
           Change within 30 days after the effective date of the Adverse Change,
           then such shall be considered a termination of Executive's employment
           by Company without cause for purposes of this Section 7(f) effective
           as of the 30th day after the effective date of the Adverse Change. If
           the Company terminates Executive's employment without cause pursuant
           to this Section 7(f), then following such termination Executive shall
           be entitled to receive such severance benefits, if any, as are then
           provided by the Company to its Executive Vice Presidents under
           Company policies or programs for senior executive officers in effect
           at such time; any bonus earned by Executive pursuant to Section 6(a)
           for a calendar year already completed but not yet paid; and any
           benefits to which Executive is entitled pursuant to Sections 6(c)
           through 6(e) up through the effective date of termination.

     shall be communicated in a written Termination Notice to Executive. For
     purposes of this Agreement, a "Termination Notice" shall mean a notice from
     the Chief Executive Officer which shall indicate the specific termination
     provision in this Agreement relied upon and, if applicable, shall set forth
     in reasonable detail the facts and circumstances providing a basis for
     termination of Executive's employment under the provision so indicated.

 9.  SUCCESSORS AND ASSIGNS. This Agreement and all rights under this Agreement
     shall be binding upon, inure to the benefit of, and be enforceable by the
     parties hereto and their respective personal or legal representatives,
     executors, administrators, heirs, distributees, devisees, legatees,
     successors, and assigns. This Agreement is personal in nature, and neither
     of the parties to this Agreement shall, without the written consent of the
     other, assign or transfer this Agreement or any right or obligation under
