b.    Successors. This Agreement is personal to Director and, without the prior written consent of the Company, shall not be assignable by Director. Notwithstanding the foregoing, in the event of the Director’s death following the Departure Date, this Agreement shall remain in full force and effect and the personal representative of the Director’s estate shall be entitled to exercise any Equity Interest consisting of a stock option or other exercisable Equity Interest in accordance with Section 2 of this Agreement. This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.

c.    Amendment; Waiver; Survival. No provisions of this Agreement may be amended, modified, or waived unless agreed to in writing and signed by Director and by a duly authorized officer of the Company.

f.    Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original but all of which together will constitute one and the same instrument.

g.    Entire Agreement. This Agreement sets forth the final and entire agreement of the parties with respect to the subject matter hereof and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by the Company and Director, or any representative of the Company or Director, with respect to the subject matter hereof.
