 ZIONS BANCORPORATION, a corporation duly organized and existing under the laws of the State of
Utah (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of Two
Hundred Ninety-Five Million Six Hundred Thirty Thousand Dollars ($295,630,000) on December 10, 2009, and to pay interest thereon from December 11, 2007 or from the most recent Interest Payment Date to which interest has been paid or duly
provided for, quarterly on March 10, June 10, September 10 and December 10 in each year (each such date, an “Interest Payment Date”), commencing March 10, 2008. Interest will accrue at the Floating
Interest Rate (as defined below), until the principal hereof is paid or made available for payment. Any premium and any such installment of interest that is overdue at any time shall also bear interest (to the extent that the payment of such
interest shall be legally enforceable), at the rate per annum at which the principal then bears interest, from the date any such overdue amount first becomes due until it is paid or made available for payment. Notwithstanding the foregoing, interest
on any principal, premium or installment of interest that is overdue shall be payable on demand. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 1, June 1, September 1 or
December 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. 
 The Floating Interest Rate shall be, for each Interest Period (as defined below), a per annum rate in effect for each day of such Interest Period equal to LIBOR (as defined below) plus 150 basis points, as determined
by the Calculation Agent (as defined below). The Floating Interest Rate for each Interest Period will be set quarterly on the first day of each Interest Period commencing December 11, 2007 (each such date, an “Interest Reset Date”).
The amount of interest for each day that this Security is outstanding (the “Daily Interest Amount”) shall be calculated by dividing the interest rate in effect for that day by 360 and multiplying the result by the outstanding principal
amount of this Security. The amount of interest to be paid on this Security for each Interest Period shall be calculated by adding the Daily Interest Amount for each day in such Interest Period. 
 In the event that an Interest Payment Date is not a Business Day, interest will be paid on the next day that is a Business Day, with the same force and
effect as if made on the Interest Payment Date, and without any interest or other payment with respect to the delay. If the date of Stated Maturity for the principal falls on a day that is not a Business Day, the payment of the principal amount of
this Security will be made on the next succeeding Business Day and no interest will accrue for the period from and after such date of Stated Maturity. If any Interest Reset Date for the Security falls on a day that is not a Business Day, the
Interest Reset Date will be postponed to the next day that is a Business Day; if that 








 
Business Day is in the next succeeding calendar month, the Interest Reset Date will be the immediately preceding Business Day. “Business Day,” with
respect to this Security, is a Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in Salt Lake City, Utah or New York City, New York generally are authorized or required by law or executive order to close,
that is also a London Business Day (as defined below). 
 “Calculation Agent” means any Person authorized by the Company to
calculate the relevant rate of interest to be paid on this Security on behalf of the Company. The calculation agent is initially Zions Direct, Inc. until such time as the Company appoints a successor calculation agent. 
 “London Business Day” is any day in which dealings in United States dollars are transacted or, with respect to any future date, are expected to
be transacted in the London interbank market. 
 “LIBOR,” with respect to any Interest Period, shall be the rate (expressed as a
percentage per annum) for deposits in United States dollars for a three-month period beginning on the relevant Interest Reset Date that appears on Reuters Page LIBOR01 (as defined below) as of 11:00 a.m., London time, on the Determination Date.
If Reuters Page LIBOR01 does not include this rate or is unavailable on the Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected by the Calculation
Agent, to provide that bank’s offered quotation (expressed as a percentage per annum) as of approximately 11:00 a.m., London time, on the Determination Date to prime banks in the London interbank market for deposits in a Representative
Amount (as defined below) in United States dollars for a three-month period beginning on the first day of the applicable Interest Period. If at least two offered quotations are so provided, LIBOR for the Interest Period will be the arithmetic mean
of those quotations. If fewer than two quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected by the Calculation Agent, to provide that bank’s rate (expressed as a percentage per
annum), as of approximately 11:00 a.m., New York City time, on the Determination Date for loans in a Representative Amount in United States dollars to leading European banks for a three-month period beginning on the first day of the applicable
Interest Period. If at least two rates are so provided, LIBOR for the Interest Period will be the arithmetic mean of those rates. If fewer than two rates are so provided, then LIBOR for the Interest Period will be LIBOR in effect with respect to the
immediately preceding Interest Period. 
 “Determination Date” with respect to an Interest Period shall be the second London
Business Day preceding the Interest Reset Date. For the first interest period, the determination date was December 7, 2007. 
 “Interest Period” shall mean each period commencing on and including the tenth day of each of March, June, September and December and ending on and including the ninth day of each of the following March, June, September and
December, and, in the case of the last such period, ending on but not including the Principal Payment Date. The first interest period shall commence on and include December 11, 2007 and end on and include March 9, 2008. 
 “Representative Amount” shall mean a principal amount that, in the Calculation Agent’s judgment, is representative for a single
transaction in the relevant market at the relevant time. 
 “Reuters Page LIBOR01” means the display so designated on the Reuters
3000 Xtra (or such other page as may replace that page on that service, or such other service as may be nominated as the information vendor, for the purpose of displaying rates or prices comparable to the London Interbank Offered Rate for U.S.
dollar deposits). 
  







 All percentages resulting from any of the above calculations shall be rounded, if necessary, to the
nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such
calculations shall be rounded to the nearest cent (with one-half cent being rounded upwards). 
 The Floating Interest Rate shall in no event
be higher than the maximum rate permitted by the law of the State of New York or, if higher, the law of the United States of America. 
 Upon
the request of the Holder of this Security, the Calculation Agent shall provide the interest rate then in effect with respect to this Security. All calculations of the Calculation Agent, in the absence of manifest error, shall be conclusive for all
purposes and binding on the Company and the Holder of this Security. So long as the Floating Interest Rate is required to be determined with respect to this Security, there shall at all times be a Calculation Agent. In the event that any then acting
Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail duly to establish the Floating Interest Rate for any Interest Reset Period, or that the Company proposes to remove such Calculation Agent, the Company
shall appoint, with the written consent of the Trustee, which consent shall not be unreasonably withheld, another Person which is a bank, trust company, investment banking firm or other financial institution to act as the Calculation Agent.

 Payment of the principal of (and premium, if any) and any such interest on this Security will be made at the office or agency of the
Company maintained for that purpose in Salt Lake City, Utah in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the
option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 
 Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 
  







 IN WITNESS WHEREOF, the Company has caused this instrument

 (Reverse of Security) 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under a Senior Debt Indenture, dated as of
September 10, 2002 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Trust Company, N.A., as successor to J.P. Morgan Trust Company,
National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face
hereof. 
 The Securities of this series 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 Securities being redeemed plus accrued interest thereon through the Redemption Date. The Company shall notify the Holder, in writing, of the optional redemption not less than ten Business Days
prior to the Redemption Date. 
 There is no sinking fund for the Securities of this series. 
 The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of
Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of
Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 66 2/3% in principal amount of the Securities at the time Outstanding
of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon
such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to
institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default
with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder 








 
of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed
herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The
Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series
are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee
nor any such agent shall be affected by notice to the contrary. 
 This Security shall be governed by and construed in accordance with the
laws of the State of New York, but without regard to principles of conflict of laws.
