The undersigned represents and warrants that he or she (except to the extent indicated below) is the sole record and/or beneficial owner of (and has sole rights to vote and to dispose of) the number of shares of AJSB Common Stock indicated beside his or her signature below.

This Voting Agreement shall be effective from the date hereof and shall terminate and be of no further force and effect upon the earlier of (a) the consummation of the Holding Company Merger; (b) the termination of the Agreement and Plan of Merger in accordance with its terms; or (c) the taking of such action whereby a majority of AJSB’s Board of Directors, in accordance with the terms and conditions of Section 5.06 of the Agreement and Plan of Merger, withdraws its favorable recommendation of the Agreement and Plan of Merger to the stockholders of AJSB.
