<PAGE>

shall be designated by the Employee and one of whom shall be designated by
the Employer. If such physicians are unable to agree as to the physical or
mental capacity of the Employee, such physicians shall designate a third

of Directors in such regard and whose determination in that matter shall be
conclusive and binding on the parties hereto. In the event of a termination
pursuant to this paragraph (b), the Employer shall be relieved of all its
obligations under this Agreement, except that the Employer shall pay to the
Employee or his estate in the event of his subsequent death, the Employee's
salary and benefits through the end of the 90-day period following the month

Agreement, the Employer may discharge the Employee for cause and terminate
this Agreement without any further liability hereunder to the Employee or his
estate, except the obligation of the Employer to pay the Employee's minimum

written policies or directives established by the Board, (iii) has willfully
and persistently failed to attend to his duties, (iv) has committed acts
amounting to gross negligence or willful misconduct to the detriment of the
Employer or its affiliates. If the Employee shall be discharged by the
Employer for any reason other than those enumerated in this paragraph (c),
such discharge shall be deemed a "discharge without cause." In the event of a
discharge without cause or death (a), the Employer shall continue to pay the
Employee's base salary for the term of the contract and agrees to make all
payments for Employee for health insurance for Employee as were being paid by
or for the Employee upon the same terms as of the day preceding his
termination, said payments to be made under COBRA for the maximum period of
time allowed by COBRA. Further, any termination except for those enumerated
in this paragraph (c), any vesting stipulations for any compensation
contemplated herein or by subsequent agreement shall be determined as fully
vested as of the date of discharge. In the event of the Employer's insolvency
or inability at that time of being able to pay the termination costs accruing
to Employee of such event as herein specified, the Employers shall have the
option of settling any amounts still due to the Employee in common Stock at
the same per share price value as the Employers settlement of the 12% Senior

of this Agreement, the Employee, at his option, may terminate this Agreement

Agreement or (ii) sixty (60) days prior written notice. In the event of
termination pursuant to this paragraph (d), the Employer shall be relieved of
all of its obligations under this Agreement, except that the Employer shall
pay to the Employee the Employee's salary until the date of termination, plus
accrued vacation pay, if any.

                (e) CLOSE OF BUSINESS. Other than for insolvency as provided
above, should the business activities of Employer change and the Employee is

restructuring or other means prior to the end of this contract, Employee
