 UNION PACIFIC CORPORATION, a corporation duly organized and
existing under the laws of the State of Utah (herein called the “Company”, which term includes any successor under the Indenture hereinafter referred to), for value received, hereby promises to pay to 

CEDE & CO. 

or registered assigns, the principal sum of $350,000,000 at the office or agency of the Company in the Borough of Manhattan, The City of New York, on
January 15, 2045, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts, and to pay interest on said principal sum at the rate per annum specified
above semiannually on January 15 and July 15 of each year (each, an “Interest Payment Date”), commencing January 15, 2015. Interest shall be paid from the Interest Payment Date, as the case may be, next preceding the
date of this Note to which interest on the Notes has been paid or duly provided for (unless the date hereof is the date to which interest on the Notes has been paid or duly provided for, in which case from the date of this Note), or, if no interest
has been paid on the Notes or duly provided for, from August 12, 2014 until payment of said principal sum has been made or duly provided for. Notwithstanding the foregoing, if the date hereof is after January 1 or July 1 (each, a
“Regular Record Date”) and before the next succeeding Interest Payment Date, this Note shall bear interest from such Interest Payment Date, as the case may be; provided, however, that if the Company shall default in the
payment of interest due on such Interest Payment Date, then this Note shall bear interest from the next 







 
preceding Interest Payment Date to which interest on the Notes has been paid or duly provided for, or if no interest has been paid on the Notes or duly provided for, from August 12, 2014.
The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, except as provided in the Indenture dated as of April 1, 1999 (herein called the “Indenture”), between the Company and The
Bank of New York Mellon Trust Company, N.A., as successor to The Bank of New York Mellon (formerly known as The Bank of New York), as successor to JPMorgan Chase Bank, N.A. (formerly The Chase Manhattan Bank), as Trustee (herein called the
“Trustee”), be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the next preceding Regular Record Date, whether or not a Business Day, and may, at the
option of the Company, be paid by check mailed to the registered address of such Person. Any such interest which is payable, but is not so punctually paid or duly provided for, shall forthwith cease to be payable to the registered Holder on such
Regular Record Date and may be paid either to the Person in whose name this Note (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 Notes not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which
the Notes may be listed and upon such notice as may be required by such exchange, if such manner of payment shall be deemed practical by the Trustee, all as more fully provided in the Indenture. Notwithstanding the foregoing, in the case of interest
payable at Maturity, such interest shall be paid to the same Person to whom the principal hereof is payable. In the event that any date on which the principal of or interest on this Note is payable is not a Business Day, then payment of the
principal or interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on the date the payment was
originally payable. 
 The Bank of New York Mellon Trust Company, N.A. is the Paying Agent and the Security Registrar with respect to the
Notes. The Company reserves the right at any time to vary or terminate the appointment of any Paying Agent or Security Registrar, to appoint additional or other Paying Agents and other Security Registrars, which may include the Company, and to
approve any change in the office through which any Paying Agent or Security Registrar acts; provided that there will at all times be a Paying Agent in The City of New York and there will be no more than one Security Registrar for the Notes.

 This Note is one of the duly authorized issue of notes, debentures, bonds or other evidences of indebtedness (hereinafter called the
“Securities”) of the Company, of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture and any other indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any Paying Agent, the Security Registrar, the Company and the Holders of the Securities and the
terms upon which the Securities are issued and are to be authenticated and delivered.

 The Securities may be issued in one or more series, which different series may be issued in
various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any),
may be subject to different covenants and Events of Default and may otherwise vary as provided or permitted in the Indenture. This Note is one of the series of Securities of the Company issued pursuant to the Indenture and designated as the 4.150%
Notes due 2045 (herein called the “Notes”). 
 At any time before July 15, 2044, the Notes will be redeemable in whole
or in part at any time and from time to time, at the option of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve
30-day months) at the Treasury Rate (as defined below) plus 15 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to the Redemption Date. 

At any time on or after July 15, 2044, the Notes will be redeemable in whole or in part at any time and from time to time, at the option
of the Company, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest on the principal amount being redeemed to the Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, (i) the yield, under the heading which represents the
average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System
and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no
maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated
from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum
equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 
 “Business
Day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York and on which banking institutions and trust companies are open for business in New York, New York. 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having
a maturity comparable to the remaining term (“Remaining Life”) of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of such Notes. 

  
 - 3 - 








 “Comparable Treasury Price” means, with respect to any Redemption Date, the
average of the Reference Treasury Dealer Quotations for such Redemption Date. 
 “Independent Investment Banker” means each
of J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. LLC or their respective successors as appointed by the Company, or, if such firms are unwilling or unable to select the
Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company. 

“Reference Treasury Dealer” means (i) each of J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith
Incorporated and Morgan Stanley & Co. LLC, and their respective successors, provided, however, that if any of the foregoing is not at the time a primary U.S. Government securities dealer in New York City (a “Primary Treasury
Dealer”), the Company shall substitute therefor another Primary Treasury Dealer and (ii) any other Primary Treasury Dealer selected by the Independent Investment Banker after consultation with the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the
average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by
such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 Notice of the
redemption will be mailed to Holders of Notes by first-class mail at least 30 and not more than 60 days prior to the Redemption Date. If fewer than all of the Notes are to be redeemed, the Trustee will select,
not more than 60 days prior to the Redemption Date, the particular Notes or portions thereof for redemption from the Outstanding Notes not previously called for redemption by such method as the Trustee deems fair and appropriate. Notwithstanding
Section 1104 of the Indenture, the notice of any such redemption occurring before July 15, 2044 need not set forth the Redemption Price but only the manner of calculation thereof. The Company shall give the Trustee notice of the Redemption
Price for any such redemption promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

If a Change of Control Repurchase Event occurs with respect to the Notes, unless the Company has exercised its right to redeem the Notes as
described above, and notice of such redemption has been given to the Holders of the Notes in accordance with the Indenture, the Company will be required to make an offer to each Holder of the Notes to repurchase all or any part (in integral
multiples of $1,000) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of
repurchase. Within 30 days following a Change of Control Repurchase Event or, at the Company’s option, prior to a Change of Control, but after the public announcement of the Change of Control, the Company will mail a notice to each Holder of
the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and 

  
 - 4 - 








 
offering to repurchase the Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice
shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. The Company will
comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are
applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of
the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict. 

On the repurchase date following a Change of Control Repurchase Event, the Company will, to the extent lawful: 

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Company’s offer; 

(2) deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes
properly tendered; and 
 (3) deliver or cause to be delivered to the Paying Agent the Notes properly accepted, together with
an Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Company and that all conditions precedent provided for in the Indenture to the repurchase offer and to the repurchase by the Company of the Notes
pursuant to the repurchase offer have been complied with. 
 The Paying Agent will promptly mail to each Holder of Notes properly tendered
the purchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that
each new Note will be in a principal amount of an integral multiple of $1,000. 
 The Company will not be required to make an offer to
repurchase the Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all
Notes properly tendered and not withdrawn under its offer. 
 “Below Investment Grade Ratings Event” means, with respect to
the Notes on any day within the 60-day period (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (1) the
occurrence of a Change of Control; or (2) public notice of the occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the Notes are rated below Investment Grade by each of the Rating Agencies.


  
 - 5 - 








 
Notwithstanding the foregoing, a Below Investment Grade Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a
particular Change of Control (and thus shall not be deemed a Below Investment Grade Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this
definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a
result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Ratings Event). 

“Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation)
the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act), other than the Company or its subsidiaries, becomes the beneficial owner (as defined in Rules 13d-3 and
13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company’s Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or
changed measured by voting power rather than number of shares. 
 “Change of Control Repurchase Event” means the occurrence
of both a Change of Control and a Below Investment Grade Ratings Event with respect to the Notes. 
 “Investment Grade”
means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the
equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the Company. 

“Moody’s” means Moody’s Investors Service, Inc. 

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to
rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under
the Exchange Act, selected by the Company (as certified by a Board Resolution) as a replacement agency for Moody’s or S&P, or both of them, as the case may be. 

“S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc. 

“Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of
any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of all of the Notes may be declared due and
payable in the manner, with the effect and subject to the conditions provided in the Indenture.

 The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee
to enter into supplemental indentures to the Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of the
Securities of each series under the Indenture with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected thereby on behalf of the Holders of all Securities
of such series. The Indenture also permits the Holders of a majority in principal amount of the Securities at the time Outstanding of each series, 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 and their consequences with respect to such series under the Indenture. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all
future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note or such other Notes. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and interest on this Note at the place, rate and respective times and in the coin or currency herein and in the Indenture prescribed. 

As provided in the Indenture and subject to the satisfaction of certain conditions therein set forth, including the deposit of certain trust
funds in trust, the Company shall be deemed to have paid and discharged the entire indebtedness represented by, and the obligations under, the Securities of any series and to have satisfied all the obligations (with certain exceptions) under the
Indenture relating to the Securities of such series. 
 The Notes are issuable in registered form without coupons in denominations of $1,000
and any integral multiple of $1,000. Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company in the Borough of Manhattan, The City of New York, designated for
such purpose, and in the manner and subject to the limitations provided in the Indenture. 
 Upon due presentment for registration of
transfer of this Note at the office or agency of the Company in the Borough of Manhattan, The City of New York designated for such purpose, a new Note or Notes of authorized denominations for a like aggregate principal amount will be issued to the
transferee in exchange therefor, subject to the limitations provided in the Indenture. 
 No charge shall be made for any such transfer or
exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge imposed in connection therewith. 

Except as otherwise provided in the Indenture, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

  
 - 7 - 








 Unless otherwise defined herein, all terms used in this Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture. 
 This Note shall be construed in accordance with and governed by the laws of
the State of New York. 
 Unless the certificate of authentication hereon has been manually executed by or on behalf of the Trustee under
the Indenture, this Note shall not be entitled to any benefits under the Indenture, or be valid or obligatory for any purpose.
