In a presentation at a bank investor conference on November 15, 2006, Zions’ Chairman and CEO, Harris Simmons, expects to make the following statements:

Zions Bancorporation has changed a key target capital ratio from 6.25-6.50% tangible common equity to 6.25-6.50% tangible equity. In conjunction with this change, Zions expects to issue in the fourth quarter approximately $200 million of non-cumulative perpetual preferred stock with a floating dividend rate, which is expected to add about 30 basis points to tangible equity. The initial annual run rate of dividends on this preferred stock is expected to be approximately $12 million, assuming the issuance of $200 million of preferred stock.

With the addition of this preferred stock to its capital structure, Zions currently estimates that its tangible equity ratio will be approximately 6.4% at December 31, 2006. The Company expects to be in a position to resume its share repurchase program early in 2007.

Holders were notified on November 14, 2006 that Zions intends to call $176.3 million of 8.536% trust preferred stock issued by Zions Institutional Capital Trust A which holds subordinated debentures of Zions First National Bank. The call date will be December 15, 2006. From a rating agency perspective, this trust preferred is an expensive form of subordinated debt and the 8.536% trust preferred stock does not provide Zions any equity credit.

Zions expects to incur a pre-tax expense in the fourth quarter of 2006 of approximately $7.3 million due to the call premium; however, calling this issue will reduce pre-tax interest expense by approximately $14.5 million annually.
