Effective December 31, 2006, certain Stockholder's and Voting Agreements by and among Zion, certain of its executive officers and certain of its shareholders (the "2005 Voting Agreements") terminated in accordance with their terms. With the termination of these agreements, 1,122,785 of our common shares previously subject to the irrevocable proxies provided for in the agreements were freed from voting limitations and may be freely voted by the holders of such shares. Specifically, the termination of the 2005 Voting Agreements affect shares of common stock as follow: (i) 93,000 shares previously subject to an agreement among the Company, John Brown (our Chairman) and certain shareholders; (ii) 311,918 shares previously subject to an agreement among the Company, Eugene A. Soltero (our CEO) and certain shareholders; (iii) 423,834 shares previously subject to an agreement among the Company, Richard Rinberg (our President) and certain shareholders; (iv) 157,450 shares previously subject to an agreement among the Company, Philip Mandelker (our General Counsel and Secretary) and certain shareholders; and (v) 136,583 shares previously subject to an agreement among the Company, Glen H.
