(c) Forfeiture. A Director's right to withdraw Deferred Fes shall be automatically and completely forfeited in the event a Director is removed from the Board of the Company or the Bank for "cause".

NON-TRANSFERABILITY. Neither the Directors Fees deferred under this Plan, nor the interest earned thereon, may be pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent and distribution, or pursuant to the terms of a "qualified domestic relations order" (within the meaning of Section 414(p) of the Code and the regulations and rulings thereunder). 8. EFFECTIVE DATE. The Plan shall become effective as of January 1, 2001 (the "Effective Date"); provided, however, the first election to be made by the Directors under the Plan shall be no later than December 1, 2000. 9. AMENDMENT AND TERMINATION OF THE PLAN. The Board may from time to time amend, suspend or terminate the Plan; provided that no provision hereof may be amended more than once every six months (other than to comport with changes in the Code, the Employee Retirement Income Security Act of 1974, as amended, or the rules thereunder), and provided further that any amendment that is "material" within the meaning of Rule 16b-3 of the Securities Exchange Commission shall be subject to stockholder approval.

NO EMPLOYMENT OR OTHER RIGHTS. 3 4 In no event shall a Director's eligibility to participate or participation in the Plan create or be deemed to create any legal or equitable right of the Director, or any other party to continue service with the Company or the Bank in any capacity. Without limiting the foregoing, neither a Director's eligibility to participate in the Plan, nor the election to so participate, shall be construed to guarantee or assure any Director of continued service as a Director or reelection as a Director at any time. 12.
