     NOW, THEREFORE, in consideration for the mutual promises contained herein, the Policy is amended as follows.

1.

The following new Section 2.4 is hereby added immediately following Section 2.3:

     “2.4. “Covered Employee” means an Executive who has been designated by the Company’s Board of Directors as an executive officer of the Company.”

          (C) the Executive’s Severance Multiplier times (x) the Executive’s annual base salary as in effect immediately prior to the date of termination and (y) the Executive’s target bonus for the year in which termination occurs, in each case to be paid in a lump sum within 30 days after the date of termination; and”
