The Board shall nominate Seidman for election at the 2000 Annual Meeting for a term expiring in 2003. The Board shall solicit proxies for Seidman's election along with the solicitation of proxies by the Board for the other three nominees nominated by the Board. 2.

Daly, Marvin R. Leroy, Jr. and Dr. Ronald S. Tecler. 4. It is understood that John M. Lisicki is the only current member of the Company's Board of Directors who is eligible to seek reelection to the Board in the year 2001. Therefore, the Seidman Group shall vote all stock of Ambanc owned or controlled by any of them as of the record date for the 2001 Annual Meeting of Stockholders in favor of the reelection of John M. Lisicki as a director of the Company. 5. The Seidman Group will not acquire any shares of common stock of Ambanc which would cause its percentage ownership of the issued and outstanding common stock of Ambanc to exceed 14.9% through the period ended March 31, 2001.

Subject to the provisions of Paragraph 4 to this Agreement, this provision shall not apply to the nomination of directors and the solicitation of proxies for such nominees, or any other matter arising, at the Annual Meeting of Stockholders to be held in 2001 or thereafter. Nothing contained in this paragraph shall be interpreted to prohibit Seidman from voting, as a director, in such manner as he deems appropriate on any matter which may come before the Board of Directors or any committee of Ambanc or the Bank, nor shall the same prohibit him from including, in any disclosure made by Ambanc pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), any statement explaining his vote if he is required by law to include such an explanation in such disclosure. 7. Seidman & Associates, LLC will withdraw its nominations of Lawrence B.

The Seidman Group will not take any action indirectly, or induce any other person or entity to take any action which, if taken directly by the member of the Seidman Group, would be in violation of this Agreement, nor will the Seidman Group take any action which would reasonably be anticipated to thwart any of the provisions of this Agreement. All the members of the Seidman Group individually, and all members of limited liability companies, partners of partnerships, stockholders, directors and officers of corporations, trustees and beneficiaries of trusts, and other persons holding comparable positions in any other entities, making up the Seidman Group shall be personally bound by the provisions of this Agreement which by their terms are applicable to the Seidman Group.
