     NOW THEREFORE, in consideration of the premises and the parties
intending to be bound, agree as follows:

     2.    Amendment. Employment Agreements and amendments thereto be and
are further modified and amended by the following provisions providing for
an executive deferred retirement plan to the benefit of the employee.

     3.    Term Extended. The term of the current Employment Agreements
and the amendment be and are hereby extended for three (3) additional
years to December 31, 2003.

     4.    Terms and Conditions. Terms and conditions of this executive
deferred retirement program are as follows:

           a.    The program includes the named Employee.

           b.    Except in the event of the death or disability of the
                 Employee or of a change of control of the company, the
                 benefits of the program will vest upon the completion of
                 five years of employment commencing January 1, 1999. In
                 the event of death or disability or of a change of
                 control vesting will be immediate for the Employee who
                 has not yet completed the additional five years of
                 service.

           c.    When the vesting requirements have been met the Employee
                 will be entitled to receive an annual payment equal to
                 $60,000 per year upon retirement from the company
                 beginning July 1, 2004, and continuing for a total of
                 ten payments. If the Employee continues to be employed
                 by the company the start of the payments will be delayed
                 until the first of July following his retirement from
                 the company. The employee may also elect to have his
                 payments deferred for a period of up to 5 years
                 following his retirement. In the event of employment
                 beyond the five year vesting period or the deferral of

                 payment following retirement the amount of the annual
                 benefit will be increased by 10.75 percent compounded
                 annually for each additional year of employment and/or
                 each year which the beginning of payment is deferred.
                 (See schedule in paragraph five (5) below)

           d.    The Employee and/or his spouse shall be entitled to
                 participate in the group health plan of the company or
                 its successors or for as long as either shall live by
                 paying the same premium for such coverage as is charged
                 to other employees of the company or its successor.

           e.    In the event of the death or disability of the Employee,
                 payments due under this retirement program shall be made
                 as designated by the Employee for any remaining unpaid
                 benefits. In the event the Employee is still employed at
                 the time of his death, his designees will receive the
                 full amount specified in the retirement program paid
                 over a 10 year period commencing with July 1 following
                 his death in addition to any other benefits specified in
                 the contract.

           f.    In the event the company or a majority of its assets are
                 acquired by another entity the benefits due under this
                 agreement will be accelerated and due immediately. In
                 the case of an employee who has already retired he shall
                 be paid a single payment equal to the sum of the
                 remaining payments he is entitled to receive. In the
                 case of an employee who has not yet retired he shall be
                 entitled to receive an accelerated retirement benefit as
                 set forth above for ten years less the period used to
                 calculate the change of control payment under Section
                 11.01 of the employment agreement as set forth in
                 "Modifications to Employment Agreement (No. 2)."

           g.    The provisions of this amendment shall survive the
                 expiration of the employment agreement and its
                 amendments.

     5.    Year  Amount
     
            5    $60,000
            6    $66,454

            8    $81,520
