Such fractional share interest shall not include the right to vote or to receive dividends or any interest thereon. 3.3. Dissenting Shares. Notwithstanding anything to the contrary herein, each Dissenting Share whose holder, as of the Effective Date, has not effectively withdrawn or lost his or her dissenters' rights under the Appraisal Laws, shall not be converted into or represent a right to receive Zions Bancorp Stock or Cash Component, but the holder thereof shall be entitled only to such rights as are granted by the Appraisal Laws.

Dividends; Interest. No shareholder of the Company will be entitled to receive dividends on his or her Zions Bancorp Stock until he or she exchanges his or her certificates representing Company Common Stock for Zions Bancorp Stock and, if applicable, Cash Component.

Such notice shall be mailed to holders by regular mail at their addresses on the records of the Company. Zions Bancorp shall cause Zions Bank to deliver shares and cash to such holders who comply with the terms and conditions of the notice of exchange. ARTICLE IV 4.1. Counterparts.
