ADDENDUM B

    Section 2.2 of the Agreement shall be deleted in its entirety and replaced by the following:
 2.2
    
    Executives Interest. The Executive shall have the right to designate the beneficiary
of death proceeds of the Policy in the amount of one hundred thousand dollars ($100,000). The

shall have no rights or interests in the Policy with respect to that portion of the death
proceeds designated in this section 2.2 if the Executive ceases to be employed by the Employer
for any reason whatsoever prior to Normal Retirement Age (other than by reason of a leave of
absence which is approved by the Employer) and has received or had the opportunity to receive
any benefit under the Executive Salary Continuation Agreement dated June 2, 1994 and a first
and second Amendment thereto (Grandfathered Agreement) as well as the Amended and Restated
Executive Salary Continuation Agreement between the Employer and the Executive (collectively

The following Article 9 shall be added to the Agreement following Section 8.8:
 Article 9
Compliance with Code Section 409A
 9.1
    
    Definition of Specified Employee. For purposes of this Article 9, the term
Specified Employee means an employee who at the time of Termination of Employment is a key
employee of the Company, if any stock of the Company is publicly traded on an established
securities market or otherwise. For purposes of this Agreement, an employee is a key employee
if the employee meets the requirements of Code section 416(i)(1)(A)(i), (ii), or (iii)
(applied in accordance with the regulations thereunder and disregarding section 416(i)(5)) at
any time during the 12-month period ending on December 31 (the identification period). If
the employee is a key employee during an identification period, the employee is treated as a
key employee for purposes of this Agreement during the twelve (12) month period that begins on
the first day of April following the close of the identification period.
 9.2
    
    Restriction on Timing of Distributions to Specified Employees. Notwithstanding any
provision of this Agreement to the contrary, if the Executive is considered a Specified
Employee, the provisions of this Section 9.2 shall govern any distributions hereunder which
would otherwise be made to the Executive due to a Termination of Employment. Such
distributions shall not be made during the first six (6) months following Termination of
Employment unless Executive dies prior to the end of the six (6) month period. Rather, any
distribution which would otherwise be paid to the Executive during such period shall be
accumulated and paid to the Executive in a lump sum on the first day of the seventh month
following the Termination of Employment. All subsequent distributions shall be paid in the
manner otherwise specified herein.
 9.3
    
    Timing of Payments. Any amounts paid to the Executive pursuant to Section 3.3 prior
to Termination of Employment shall be paid within two and one-half (2 1/2) months following
the end of the prior year and shall be treated as short-term deferrals under Code section
409A.
 9.4
    
    Change in Form or Timing of Distributions. All changes in the form or timing of the
amounts paid to the Executive pursuant to Section 3.3 must be made by written amendment to
this Agreement and must comply with the restrictions on changes to payments contained in Code
section 409A and the regulations promulgated thereunder.
 9.5
    
    Compliance with Code Section 409A. This Agreement shall be interpreted and
administered consistent with Code section 409A.
