 [REVERSE OF NOTE] 

MIDAMERICAN ENERGY COMPANY 

3.95% First Mortgage Bond due 2047 

This global Bond is one of, and a global security which represents Bonds which are part of, the duly authorized 3.95% First Mortgage Bonds due
2047 of the Company (herein called the “Bonds”), issued under an Indenture dated as of September 9, 2013, as amended and supplemented (herein called the “Indenture”), between the Company and The Bank of New York Mellon Trust
Company, N.A., as Trustee (herein called the “Trustee,” which term includes any successor Trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Bonds are, and are to be, authenticated and delivered. 

Interest on this global Bond will be payable on the Interest Payment Date or Interest Payment Dates as specified on the face hereof and, in
either case, at Maturity. Unless otherwise specified on the face hereof, payments on this global Bond with respect to any particular Interest Payment Date, redemption date or the Maturity Date will include interest accrued from and including the
applicable Original Issue Date, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, to but excluding the particular Interest Payment Date, redemption date or the Maturity Date. Interest
on this global Bond will be computed and paid on the basis of a 360-day year of twelve 30-day months. 
 All percentages resulting from any
calculation with respect to this global Bond will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (with five one-millionths of a percentage point rounded upward) and all dollar amounts used in or resulting from
any such calculation with respect to this global Bond will be rounded to the nearest cent (with one-half cent being rounded upward). 

“Business Day” means, unless otherwise specified on the face hereof, any Monday, Tuesday, Wednesday, Thursday or Friday that in the
City of New York, New York is not a day on which banking institutions are authorized or obligated by law or executive order to close. In any case when any Interest Payment Date, redemption date, or Maturity Date of any Bond shall not be a Business
Day at any Place of Payment, then (notwithstanding any other provision of the Indenture or of the Bonds) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date, redemption date or at the Maturity Date, provided that no interest shall accrue for the period from and after such Interest Payment Date, redemption date or Maturity Date, as the
case may be. 
 This global Bond is secured under the Company’s Mortgage, Security Agreement, Fixture Filing and Financing Statement
between the Company and The Bank of New York Mellon Trust Company, N.A., as amended and supplemented from time to time (the “Mortgage”). Reference is made to the Mortgage for a description of the property mortgaged and pledged and the
nature and extent of the security and to the Intercreditor and Collateral Trust Agreement among the Company, the Trustee and The Bank of New York Mellon Trust 







 
Company, N.A., as collateral trustee, and the Indenture for the rights of the holders of the Bonds and of the Trustee in respect thereof. Reference is made to the Indenture and the Mortgage for
the terms and conditions upon which the Bonds are secured and the circumstances under which additional bonds may be issued. 
 This global
Bond will be subject to redemption at the option of the Company on any date in whole or from time to time in part in increments of $2,000 or integral multiples of $1,000 in excess thereof, at the redemption prices specified in an annex attached to
this global Bond, plus accrued interest on the principal amount thereof to be redeemed to the redemption date, but payments due with respect to this global Bond prior to the redemption date will be paid to the Person in whose name this global Bond
is registered at the close of business on the relevant Record Date specified on the face hereof, all as provided in the Indenture. The Company may exercise such option by causing the Trustee to mail a notice of such redemption, not less than 30 nor
more than 60 days prior to the redemption date, in accordance with the provisions of the Indenture. In the event of redemption of this global Bond in part only, this global Bond will be cancelled and a new global Bond representing the unredeemed
portion hereof will be issued in the name of the Holder hereof. This global Bond is not subject to a sinking fund. 
 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 to be affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal amount of the Outstanding Bonds of all series that would be affected thereby. The Indenture also provides that the Holders of not less than a majority in principal amount of the
Outstanding Bonds of all affected series may on behalf of the Holders of all Bonds of such series waive certain existing Events of Default and their consequences. Any such consent or waiver of the Holder of any Bond shall bind every future Holder of
the same Bond and the Holder of every Bond issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon,
whether or not notation of such action is made upon such Bond. 
 As set forth in, and subject to, the provisions and limitations set forth
in the Indenture, the Holders of at least a majority in principal amount of the Outstanding Bonds of all series shall have any right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee. 
 THIS GLOBAL BOND IS A GLOBAL BOND REGISTERED IN THE NAME OF THE DEPOSITARY OR A
NOMINEE THEREOF AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR THE INDIVIDUAL SECURITIES REPRESENTED HEREBY, THIS GLOBAL BOND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF
THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.

unable to continue as Depositary for this global Bond or if at any time the Depositary for this global Bond shall no longer be registered or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or
regulation, the Company shall appoint a successor Depositary with respect to this global Bond. If a successor Depositary for this global Bond is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of
such condition, the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Bonds of this series, shall authenticate and deliver Bonds of this series in definitive form in an
aggregate principal amount equal to the principal amount of this global Bond in exchange for this global Bond. 
 The Company may at any
time and in its sole discretion and subject to the procedures of the Depositary determine that the Bonds of this series shall no longer be represented by a global Bond. In such event the Company shall execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Bonds of this series, shall authenticate and deliver, Bonds of this series in definitive registered form without coupons, in any authorized denominations, in an aggregate principal
amount equal to the principal amount of this global Bond, in exchange for this global Bond. 
 The Company may from time to time, without
the consent of Holders of the Bonds, create and issue further Bonds having the same terms and conditions as the Bonds in all respects, except for the Original Issue Date, issue price and, in some circumstances, the initial interest accrual date and
initial interest payment date. Additional Bonds issued in this manner will be consolidated with, and form a single series with, the Bonds and shall thereafter be deemed Bonds for all purposes. 

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

The Indenture contains provisions for the satisfaction and discharge of the Indenture upon compliance by the Company with certain conditions
specified therein, which provisions apply to this global Bond. 
 The Indenture contains provisions for the defeasance and discharge of the
Indenture upon compliance by the Company with certain conditions specified therein, which provisions apply to this global Bond.

interest on this global Bond and for all other purposes whatsoever, whether or not this global Bond be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the TIA shall be applicable and except to the extent that the law of any jurisdiction
wherein any portion of the Mortgaged Property is located shall mandatorily govern the creation of a mortgage lien on and security interest in, or perfection, priority or enforcement of the Lien of the Mortgage or exercise of remedies with respect
to, such portion of the Mortgaged Property. 
 All terms used in this global Bond which are defined in the Indenture but are not defined in
this global Bond shall have the meanings assigned to them in the Indenture.

 ANNEX 1 

OPTIONAL REDEMPTION PROVISIONS 

The Bonds will be redeemable, in whole or in part, at the Company’s option at any time or from time to time prior to maturity. Prior to
February 1, 2047 (the “2047 Par Call Date”), the Bonds will be redeemable, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of the Bonds being
redeemed and (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Bonds being redeemed that would be due if the Maturity Date of such Bonds were the 2047
Par Call Date (not including any portion of any payments of interest accrued to, but not including, the redemption date), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate, plus 15 basis points (the “2047 Make-Whole Amount”); plus, in either case, accrued and unpaid interest on the principal amount of the Bonds being redeemed to the redemption date. 

On or after the 2047 Par Call Date, the Bonds will be redeemable at a redemption price equal to 100% of the principal amount of the Bonds
being redeemed, plus accrued and unpaid interest on the principal amount of the Bonds being redeemed to the redemption date. 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the Bonds to be redeemed (assuming that the Bonds matured on the 2047 Par Call Date) 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 the Bonds. 
 “Comparable Treasury Price”
means, the Reference Treasury Dealer Quotation for such redemption date. 
 “Independent Investment Banker” means an investment
banking institution of international standing appointed by the Company. 
 “Quotation Agent” means the Reference Treasury Dealer.

 “Reference Treasury Dealer” means a primary United States government securities dealer in New York City appointed by the
Company. 
 “Reference Treasury Dealer Quotation” means, with respect to the Reference Treasury Dealer and any redemption date,
the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount and quoted in writing to the Company by such Reference Treasury Dealer at 5:00
p.m. on the third Business Day in New York City preceding such redemption date). 

  
 5 








 “Treasury Rate” means the rate per annum equal to the semi-annual equivalent or
interpolated (on a day-count basis) yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption

 Notice of any redemption will be mailed (or as long as the Bonds are represented by one or more global Bonds, transmitted in
accordance with DTC’s standard procedures therefor) at least 30 days but not more than 60 days before the redemption date to each holder of the Bonds to be redeemed. If, at the time notice of redemption is given, the redemption moneys are not
held by the Trustee, the redemption may be made subject to their receipt on or before the redemption date and such notice shall be of no effect unless such moneys are so received. Upon payment of the redemption price, on and after the redemption
date interest will cease to accrue on the Bonds or portions thereof called for redemption. 
 The Company shall give the Trustee notice of
the redemption price with respect to a redemption pursuant to the first paragraph of this Annex 1 promptly after the calculation thereof and the Trustee shall not be responsible for such calculation.
