ITEM 8.01.  OTHER EVENTS.

On December 6, 2007, Zions Bancorporation (the “Registrant”) priced Floating Rate Senior Notes due December 10, 2009 (the “Notes”). The transaction is scheduled to close on December 11, 2009. The Registrant will issue $295,630,000 aggregate principal amount of the Notes. The Notes are governed by the terms of a Senior Debt Indenture (the “Indenture”) between the Registrant and The Bank of New York Trust Company, as successor to J.P. Morgan Trust Company, National Association, as Trustee, dated as of September 10, 2002. The Registrant will pay interest on the Notes quarterly on March 10, June 10, September 10 and December 10, commencing on March 10, 2008.

The Notes are the Registrant’s senior unsecured debt obligations and will rank equally among themselves and with all of the Registrant’s other present and future senior unsecured indebtedness.

The Notes may be redeemed, in whole, but not in part, on December 10, 2008 or on any interest payment date thereafter by paying the principal amount of the Notes being redeemed plus accrued interest thereon through the redemption date. The Registrant will notify the holder, in writing, of the optional redemption not less than 10 business days before the redemption date.

Under the Indenture, the filing for bankruptcy by the Registrant and the occurrence of certain other events of bankruptcy, insolvency or reorganization relating to the Registrant or any of its major constituent banks (currently Zions First National Bank and California Bank & Trust) are events of default with respect to the Notes. If an event of default occurs and is continuing, either the Trustee or the holders of at least 25% in principal amount of the outstanding Notes may accelerate the maturity of all Notes.
