      WHEREAS, THE COMPANY and EMPLOYEE agree that it is in the
best interests of both parties that EMPLOYEE terminate his
employment with THE COMPANY.

      NOW, THEREFORE, in the interest of fully and finally
resolving all matters and disputes arising out of or in any way
connected to the employment of EMPLOYEE by THE COMPANY, and in
consideration of the mutual promises and covenants contained

($7,692.31), less all applicable deductions<PAGE>
<PAGE>
required by law and/or described in this Agreement. Such severance
shall be paid to EMPLOYEE in bi-weekly installments, such
installments to coincide with the regular payroll dates of THE

expiration of the seven-day revocation period described in Section
19, below.

      (b) THE COMPANY will deduct the following from each payment
made to EMPLOYEE under the terms of subsection 2(a): a) EMPLOYEE's
FICA and Medicare contributions, if any, as required by law; b)
Federal and State income taxes; c) health and dental insurance
premium contributions, as described in Section 3 below; d) any
other deductions required by law or authorized in writing by
EMPLOYEE.

      3. (a) During the Initial Severance Period and the Extended
Severance Period, if any, or such earlier date as EMPLOYEE becomes
eligible for coverage under the comparable long term disability
and/or life insurance plans of another employer, THE COMPANY will
continue in effect the long term disability and life insurance
coverage that was in effect for EMPLOYEE immediately prior to May
8, 1998.

      (b) During the Initial Severance Period and the Extended
Severance Period, if any, or such earlier date as EMPLOYEE becomes
eligible for coverage under the comparable group medical and/or
dental plan of another employer, THE COMPANY will also continue in
effect medical and dental insurance coverage for EMPLOYEE and his
eligible dependents, provided that EMPLOYEE shall be required to
continue to pay such premium contributions as may be in effect for
THE COMPANY's active employees. Such premium contributions shall
be deducted from the severance checks described in Section 2(a) of
this Agreement until the expiration of the Initial Severance
Period or the Extended Severance Period, as the case may be, and
thereafter shall be remitted by EMPLOYEE directly to THE COMPANY
on the first day of czech subsequent month.

family and personal and household effects to Florida, provided

payable to EMPLOYEE hereunder.
