adjustment in accordance with the Company's customary practice with respect to
its Corporate Resources.

                  (c) Employee is eligible to participate in Company's long term

options with dividend equivalents. Employee acknowledges, understands and agrees
that any grant to Employee under Company's long term incentive plan for 1996 and
subsequent years is subject to the sole and complete discretion of Company's
Board of Directors.

         3. Additional Benefits. During his employment, Employee will be
entitled to participate in the pension, welfare benefit and fringe benefit plans
and programs then maintained by the Company for its management employees, all in
accordance with their terms.

         4. Special Bonus Payment. Employer shall pay Employee a special bonus
in an amount equal to fifty percent (50%) of the gross amount Employee is
required to pay to Marquette Electronics ("Marquette") for partial repayment of
the sign-on bonus paid to Employee by Marquette when Employee joined Marquette.
Employee shall provide Company with such written evidence of such repayment as
Company shall reasonably request. Such special bonus shall be paid by Company
within 20 days after its receipt of such evidence. The full amount of such
special bonus shall be repaid to Company by Employee in the event that Employee

under the Split-Dollar Life Insurance and Collateral Assignment Agreements for
life insurance policies for Employee originally purchased under Company's Key
Management Life Insurance and Estate Preservation Plans and subsequently
transferred to and assumed by Marquette in connection with Employee's employment
by Marquette. Company will make a supplemental premium payment in respect of
such policies in an amount equal to the amount which is recoverable by Marquette

with Marquette. Employee shall use his best efforts to provide Company with such
written evidence of the amount so recoverable by Marquette as Company shall
reasonably request.

to the difference between (A) the pension benefit to which Employee would have

formula in Company's pension plans immediately prior to May 1, 1995 and adjusted
for amounts previously paid to Employee under Company's pension plans, and (B)

years of service subsequent to the Hire Date.

         7. Termination of Employee. Employee acknowledges, understands and
agrees that he is an at will employee and the Company may terminate his
employment with or without cause. If Company terminates Employee other than for
cause or unsatisfactory performance prior to the time when he would have been
eligible for a "service pension" under Company's pension plans as they existed

pension formula in the Company's pension plans immediately prior to May 1, 1995
and adjusted for amounts previously paid to Employee under Company's pension
plans and (B) the amount actually payable to Employee under the Company's

addition to any other remedy the Company may have, that the Company will be
entitled to an injunction restraining Employee from any actual or threatened
breach of that paragraph, an accounting of all profits or benefits arising from
such breach and any other appropriate remedy without any bond or other security
