Grant Street Group Develops ESOARS Auction Website For Zions Bancorporation

June 29, 2006

Pittsburgh, PA (June 29, 2006) — Zions Bancorporation announced today that it has successfully completed the first auction of Employee Stock Option Appreciation Rights Securities (ESOARS). Fifty-seven participants submitted 1,149 bids in the auction, held on June 28 and 29, for 93,610 ESOARS units. The market-clearing price was $7.50 and ESOARS units were allocated to 21 bidders. A complete summary of the bidding, as well as further information about ESOARS can be found at Zions Direct, a non-banking broker-dealer subsidiary of Zions Bancorporation, acted as auction agent. The software for the auction was developed by Grant Street Group.

These new securities were offered to provide a market basis that might be used to help Zions estimate the fair value of stock options granted to employees in order to comply with Statement of Financial Accounting Standards (SFAS) No. 123R, which requires companies to expense these options. The current valuation practice is to use modifications of standard option pricing models. However, these models were not designed to estimate the value of employee stock options and may not accurately reflect their actual value.

“We are pleased with the results of this auction, and the interest it generated,” said W. David Hemingway, senior investment officer and executive vice president. “We now intend to have discussions with the Securities and Exchange Commission regarding the use of this valuation method for expensing employee stock options. Ultimately, we hope to be able to help other option-granting companies use the method we have developed to obtain a market valuation of their option grants.”
