      A. Wiskind has been employed by Myers for many years and Wiskind is
retiring effective April 20, 2005.

intending to be legally bound, mutually agree as follows:

      1. Retirement from Active Employment. Wiskind is retiring effective April
20, 2005.

shall under this SERP Agreement pay to Wiskind the sum of Two Thousand
Eighty-Three and 33/100 Dollars ($2,083.33) per month for a period of ten (10)
years. If Wiskind dies before the expiration of the payment period, then said
monthly payments after Wiskind's death and during the remaining term of the
payment period, shall be made by Myers to Edith Wiskind, Wiskind's surviving
spouse, until her death or the balance of the original ten (10) year period,
whichever date is first in time.

      3. Assignability. Except to the extent that this provision may be contrary
to law, no assignment, pledge, collateralization, hypothecation or attachment of
any of the benefits under this Agreement shall be valid or recognized by Myers.

      4. Facility of Payments. If Wiskind shall, in the sole opinion of Myers,
be physically or mentally incapacitated to receive or properly receipt for such
payments, Myers may make such payments to any member of the family of Wiskind
for the use and benefit of Wiskind or to any person or institution providing
care for Wiskind; and all payments so made by Myers shall, to the amounts
thereof, fully discharge and acquit Myers.

      5. Rights. This SERP Agreement creates no obligation of Mysers to employ
Wiskind. Further, this SERP Agreement does not create any other rights in
Wiskind or obligations on the part of Myers, except those set forth in this SERP
Agreement.
