“Notwithstanding anything else in this Plan to the contrary, the Participant’s employment shall not be deemed to have been terminated for purposes of the Plan unless and until Participant has a “separation from service” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated thereunder (hereinafter referred to as a “Separation from Service”).”

3.           Amendment to Section 5.2(b) of the Plan. Section 5.2(b) is hereby amended and restated in its entirety to read as follows:

7.           Deletion of Section 9.2 of the Plan. Section 9.2 of the Plan is hereby deleted in its entirety.

8.           Capitalized Terms. Capitalized terms herein shall have the meanings ascribed to them in the Plan except as otherwise expressly provided in this Amendment.
