THE AUCTION

2.1 Appointment. The Issuer hereby appoints the Auction Agent as the non-exclusive auction agent for the Issuer with respect to each Auction of the Securities, and the Auction Agent hereby accepts such appointment as the Auction Agent, in accordance with and pursuant to the terms and provisions of this Agreement. For the avoidance of doubt, the Auction Agent understands and agrees that, as between the Parties, the Issuer shall have the right but not the obligation, in its sole and absolute discretion, to (i) resolve any and all questions that may arise with respect to an Auction, including the suitability of a Registered Bidder or Qualified Bidder, and to waive any defect or irregularity in any documentation submitted by a prospective bidder, Registered Bidder or Qualified Bidder in connection with an Auction or registration therefor; (ii) waive any and all requirements that may otherwise be imposed on any Registered Bidder or Qualified Bidder hereunder in connection with an Auction; and (iii) ultimately determine the final allocation of Securities hereunder; provided, however, that notwithstanding anything herein to the contrary, there shall be no waiver of any information required by applicable law including without limitation the Bank Secrecy Act and the Patriot Act.

2.2 Preparation for the Auction.

(a) Bidder Registration. The Auction Agent shall oversee the registration of prospective bidders. Prospective bidders will be allowed to access and complete Bidder Registration Forms on the Website. The Auction Agent shall collect from each prospective bidder any and all relevant contact information, including an e-mail address, as may be required in connection with the registration of such prospective bidder.

(b) Bidder Registration Forms. The Auction Agent’s Investment Center shall, to the extent practicable, attempt to answer questions from prospective bidders with respect to the Bidder Registration Form. Once a prospective bidder has properly completed a Bidder Registration Form and submitted such form to the Auction Agent through the Website, such prospective bidder will become a Registered Bidder.

(c) Auctions. The Issuer shall inform the Auction Agent each time the Issuer desires to make an offering of Securities pursuant to an Auction hereunder, including the date or dates of such Auction, and the par amount, maturity, coupon rate and any other details desired by the Issuer for the Securities to be offered at such Auction, whereupon an Auction Document reflecting such details shall be prepared and, if required, filed with the SEC. Notwithstanding anything to the contrary

4

contained in this Agreement, the Auction Agent shall have the right, in its sole discretion, to: (i) accept or reject, in whole or in part, any offer of the Issuer to sell Securities through an Auction hereunder; and (ii) accept or reject, in whole or in part, any proposed purchase of Securities pursuant to an Auction. The Issuer may instruct the Auction Agent at any time to suspend solicitation for bids and “Buy Today” Purchases at any Auction and to suspend purchases of Securities pursuant to any Auction. Upon receipt of such instructions, the Auction Agent shall thereupon suspend such solicitations and purchases until such time as the Issuer has advised the Auction Agent that solicitations and purchases may be resumed.

(d) Qualified Bidders. In order to participate in a particular Auction, a Registered Bidder must first become a Qualified Bidder. In order to become a Qualified Bidder, a Registered Bidder must log into the bidder’s Bidding Account and select an Auction from the calendar page, whereupon the Registered Bidder must (i) review and acknowledge all documents pertinent to the Auction in which the bidder wishes to participate, (ii) verify that their suitability profile includes objectives and an investment time horizon that are consistent with an investment in the Securities being auctioned and (iii) authorize and direct the broker/dealer through which they will hold the Securities won in an Auction, which broker/dealer may or may not be the Auction Agent, to update their suitability profile, if necessary, to include the appropriate objectives and investment time horizon, by following the procedures outlined in the applicable Auction Document or in the Zions Direct MTN Auction Process, as applicable. No Qualified Bidder shall be obligated to submit a bid in the Auction for which such Registered Bidder has become a Qualified Bidder. The Auction Agent shall oversee the qualification of Registered Bidders in an Auction. Registered Bidders will be allowed to become Qualified Bidders on the Website as soon as practicable subsequent to the Issuer’s filing of the applicable Auction Document with the SEC.

(e) Bid Limit Parameters.

(i) Individual Maximum Bid Limit. Registered Bidders registering for the first time on the Website shall automatically qualify to bid up to a Bid Limit of $50,000 per auction. Registered Bidders that want to bid for more than that amount may contact the Auction Agent to request a greater Bid Limit. Upon any such request by a Registered Bidder, the Auction Agent shall determine, pursuant to the Bidder Qualification Standards, whether such Registered Bidder has evidenced sufficient financial ability of payment in connection with the offering of the Securities pursuant to the Auction to be assigned a greater Bid Limit. The Auction Agent may request delivery of, and review with respect to each such Registered Bidder, applicable financial and identifying documentation and other information necessary for such determination. No Registered Bidder shall be allowed to place a bid in an auction for which such Registered Bidder has become a Qualified Bidder that exceeds such Registered Bidder’s Bid Limit.

(ii) Minimum Bid Prices. The Issuer may establish a Minimum Bid Price (or an equivalent Maximum Bid Yield) for each Auction. The Auction Agent will not accept a bid price below the Minimum Bid Price. Such Minimum Bid Price will be specified in the applicable Auction Document.

(f) Bidder Communications. The Auction Agent shall use commercially reasonable efforts to timely respond to questions from prospective bidders, Registered Bidders and/or Qualified Bidders with regard to registration, the qualification and Auction process and any other questions related to an Auction.

2.3 Auction Procedure.

(a) Auction Window. The Auction Agent shall conduct each Auction exclusively through the Website during the times and dates set for the Auction as disclosed on the Website and applicable Auction Document unless the Auction is extended in accordance with the following sentence

5

(the “Auction Window”). Notwithstanding the foregoing, during the final two (2) minutes of an Auction, if there is a change in the Market-Clearing Price, or a change in the allocation of the Securities, the Auction will automatically be extended two (2) minutes from the time of such change (each occurrence, a “Two-Minute Extension”). In no event will such Two-Minute Extensions extend the Auction more than fifteen (15) minutes beyond the originally specified Auction Period.

(b) Electronic Submission Only; Submission Deadline. The Auction Agent shall accept bids and “Buy Today” Purchases from Qualified Bidders for the purchase of Notes only through the Website during the applicable Auction Window. The Auction Agent shall only accept bids and “Buy Today” Purchases properly submitted on the Website in accordance the applicable Auction Documents and Zions Direct MTN Auction Process, as applicable. Nothing in this Agreement shall be construed as prohibiting Qualified Bidders from submitting their bids or “Buy Today” Purchases by telephoning their registered representative with the Auction Agent and having such representative enter such bids or “Buy Today” Purchases on the Website on behalf of such bidder. Once the Auction Window closes, the Auction Agent shall not accept any bids or “Buy Today” Purchases, subject to the Two Minute Extension provisions provided for in Section 2.3(a), or such other procedures as may be detailed in any applicable Auction Document or the Zions Direct MTN Auction Process (the “Submission Deadline”).

(c) Concurrent Bids. Subject to section 2.2 (f), The Auction Agent shall allow a Qualified Bidder to place up to five separate, concurrent bids, each independent of the other. Each bid may be made for different numbers of Securities and for different bid prices. At the Auction Agent’s discretion, Qualified Bidders may bid on either prices or yields. If a Qualified Bidder places a bid on the basis of yield, such bid shall be deemed to be a bid at the price necessary to achieve that yield, given the other terms of the offered Securities. A Qualified Bidder who has one active bid will be able to bid up to such Qualified Bidder’s Bid Limit in that one bid. However, if a Qualified Bidder has more than one active bid, the aggregate amount of In-The-Money bids cannot exceed that Qualified Bidder’s Bid Limit. The Bid Limit shall be allocated first to the highest bid price (which may be determined by bid yield) multiplied by the number of Securities bid for at that bid price.

Any remaining Bid Limit shall then be allocated to the next highest bid price (which may be determined by bid yield) multiplied by the number of Securities bid for at that bid price. This process will continue until the Bid Limit assigned to that Qualified Bidder has been reached. The bids of a Qualified Bidder who has placed multiple bids shall be deemed to be In-the-Money only to the extent that (i) the bid price is at or above the Market-Clearing Price and (i) the aggregate dollar amount of the multiple bids that are In-The-Money is less than or equal to that Qualified Bidder’s Bid Limit.

(d) Market-Clearing Price. As soon as practicable after the Submission Deadline, the Auction Agent shall assemble all bids for the Securities received through the Website prior to the Submission Deadline in descending order of bid price and shall determine the Market-Clearing Price and which bids equal or exceed the Market-Clearing Price. The Auction Agent shall accept bids that equal or exceed the Market-Clearing Price and shall allocate the Securities pursuant to Section 2.3(e).

(e) Allocation. The Auction Agent shall allocate the aggregate principal amount of Securities available for sale through an Auction, as disclosed in the applicable Auction Document, in accordance with the following procedures, or as otherwise set forth in any applicable Auction Document. Qualified Bidders bidding above the Market-Clearing Price shall be allocated the entire quantity of Securities for which they bid; provided, however, that in no event will a Qualified Bidder be allowed to purchase more Securities than the lesser of (i) the number of Securities that that Qualified Bidder’s Bid Limit would purchase and (ii) the total number of Securities of that Qualified Bidder’s bid designated as In-The-Money by the Website. In the event that multiple Qualified Bidders bid at the Market-Clearing Price and the total quantity of Securities for which they have bid exceeds the number of available Securities not allocated to higher Qualified Bidders, the Auction Agent will allocate the remaining Securities to the bids with the earliest time stamp. Such remaining Securities will first be allocated to the bid with the earliest time stamp, then to the bid with the next earliest time stamp, and so on until all of the Securities being offered are allocated to Qualified Bidders. To preserve the Qualified Bidder’s earliest time stamp, a Qualified Bidder will be required to use an additional bid row to increase the number of Securities bid for without improving the price.

6

(f) Buy Today. If the Issuer in its sole discretion elects to allow “Buy Today” Purchases by communicating such election to the Auction Agent pursuant hereto, then during the Auction Window applicable to a particular Auction, Qualified Bidders may purchase Securities offered in the Auction by making a “Buy Today” Purchase through the Website. The price and yield at which a Qualified Bidder may make a “Buy Today” Purchase will be set by the Issuer prior to the commencement of the Auction and reflected in the applicable Auction Document. A Qualified Bidder making a “Buy Today” Purchase will be deemed to have accepted from the Issuer an offer to sell the number of Securities specified by the Qualified Bidder at the set price and yield with the related trade to occur at the same time as the Securities sold in the Auction. A Qualified Bidder shall not be allowed to make “Buy Today” Purchases that in the aggregate exceed the Qualified Bidder’s Bid Limit. Upon making a “Buy Today” Purchase, a Qualified Bidder’s Bid Limit will be automatically adjusted to reflect the amount such Qualified Bidder has allotted to the “Buy Today” Purchase thereby ensuring that the total amount a Qualified Bidder spends on any Auction is not in excess of such Qualified Bidder’s Bid Limit. The Maximum Offering will not be affected by Qualified Bidders exercising the “Buy Today” Purchase option. Furthermore, a Qualified Bidder’s “Buy Today” Purchase will not be affected by any additional Securities won by such Qualified Bidder through the Auction.

(g) Institutional Up-Sizing. Notwithstanding anything to the contrary in this Agreement, the Issuer reserves the right to sell, through the Auction Agent and outside of an Auction, additional Securities with terms identical to the Securities being auctioned and of the same series, to any institutional or individual Qualified Bidder who satisfies all of the requirements specified in the applicable Auction Document or the Zions Direct MTN Auction Process.

2.4 Notice of Auction Results.

As soon as practicable after the end of the Auction Window, the Auction Agent shall:

(a) notify by e-mail (or if no e-mail address was provided, by telephone) each Qualified Bidder whose bid was accepted of the results of the Auction, which notice shall specify at a minimum (i) that the Auction has closed; (ii) that such Qualified Bidder’s bid has, or bids have, as applicable, been accepted; (iii) the number of Securities that have been allocated to such Qualified Bidder; and (iv) the Market-Clearing Price; and

(b) cause the results of the Auction to be posted on the Website as to winning bids and the allocation of Securities.

2.5 Settlement; Payment. The Auction Agent shall follow the settlement and payment procedures set forth in the Auction Documents or the Zions Direct MTN Auction Process, as applicable.

7

2.6 Access to and Maintenance of Auction Records.

(a) The Auction Agent shall afford the Issuer, its agents, independent public accountants and counsel access at reasonable times during normal business hours of the Auction Agent to review and make extracts or copies (at the Issuer’s sole cost and expense) of all books, records, documents and other information concerning the conduct and results of the Auction, provided, however that any such agent, accountant or counsel shall furnish the Auction Agent with a letter from the Issuer requesting that the Auction Agent afford such person access at least one (1) business day prior to the date of such access. The Auction Agent shall maintain records relating to the Auction for a period of at least six years after the Auction (unless requested in writing by the Issuer to maintain such records for such longer period not in excess of eight years, then for such longer period), and such records, in reasonable detail, shall accurately and fairly reflect the actions taken by or on behalf of the Auction Agent hereunder.

In connection with the settlement by the Auction Agent of any Securities auctioned pursuant hereto, the Auction Agent shall take such actions and maintain such records as are necessary to assure compliance with the requirements of the Office of Foreign Assets Control of the United States Treasury.

2.7 Reports to Winning Bidders.

The Auction Agent shall send, or cause to be sent, all information to each Winning Bidder as may be required in accordance with applicable laws and regulations.

2.8 Auction Procedures; Amendments to the Auction Procedures.

The Zions Direct MTN Auction process is hereby incorporated in and made a part of this Agreement. Notwithstanding anything to contrary contained in this Agreement, the description of the Auction procedures may be amended or modified by indicating such amendments or modifications in any applicable Auction Document or the Zions Direct MTN Process or by other verbal or written agreement between the Auction Agent and the Issuer. Any such amendments or modifications shall be deemed to supersede this Agreement, to the extent applicable.
