Instructions for Login and Use of Zions Direct Auction Platform

Step 1 Enter “auctions.zionsdirect.com” in your internet browser and click on the “Login” button on the top right of the page.

Step 2 Enter Login and Password provided by your sales representative, then change the password as prompted.

Step 3 Enter 3 security questions (these are for easy password retrieval in the event that it is misplaced / forgotten).

Step 4 You will be returned to the Calendar page where you will see the auction for the Zions Series H Preferred Stock. Once there, click on the blue “Enter Bids” button to be directed to the Qualifications page.

Step 5 Each box on the Qualifications page must be checked before the “I Agree” button turns green and is clickable.

Step 6 You may now monitor the auction in real time by clicking on the Auction Details dropdown in the middle of the page.

Step 7 By selecting the Zions Series H Preferred Stock auction, you are able to view the Bid Page. You can input a bid on each of the 5 bid lines with varying number of units (each depositary share is 1 unit with $25 denomination) and dividend rates. Once you are satisfied that your bids are entered correctly, click “Submit”.

Step 8 After landing on the Bid Confirmation page, check to see if the bids are entered correctly by checking the “I confirm the bid shown in the table above” box, then click “Submit” to officially submit your bids. If you are outbid at any point, a warning will appear to the right of your bids.

Step 9 After you have submitted successful bids, you may return to the Bid Page to edit these bids as the auction progresses, but only if the edits are to improve a bid (i.e., once a bid is submitted you cannot increase dividend rate, only decrease).
