                              with vesting of 25,000 shares immediately and
                              25,000 shares upon completing thirteen (13) months
                              of employment. A loan to cover the state and
                              federal taxes payable in connection with the stock
                              grant. The loan will be forgiven at 20 per cent
                              per year for five years. The balance of the loan
                              plus interest is due FEI should you terminate your

                              from the date of issue. The option price will be
                              based on the market value of the stock at the date
                              of the grant or the date of employment whichever
                              is later. The exercise period is ten (10) years.
                              [Terms changed by mutual agreement to 49,380 ISO's

                              as are commensurate with your responsibilities.
                              The Committee currently considers annual grants in
                              the range of 40,000 to 50,000 shares to meet these

                              Company, the competitive environment and the
                              general outlines of the Company's existing stock
                              incentive plans. Future grants of options are
                              within the discretion of the Compensation
                              Committee and subject to the availability at the
                              time of grant of options under a
                              shareholder-approved plan. A portion of the option
                              grants or their vesting may be made contingent
