 ARTICLE I 
 DEFINITIONS 

Unless the context otherwise requires, capitalized terms used but not defined herein have the meaning set forth in the Indenture. The
following additional terms are hereby established for purposes of this Nineteenth Supplemental Indenture and shall have the meanings set forth in this Nineteenth Supplemental Indenture only for purposes of this Nineteenth Supplemental Indenture:

 “3.25% Senior Notes” has the meaning set forth in Section 201 hereto. 

“4.60% Senior Notes” has the meaning set forth in Section 301 hereto. 

“Adjusted Treasury Rate” means, with respect to any Redemption Date for any Senior Note, the rate per annum equal to the
semi-annual equivalent 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 such Redemption Date.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as
having a maturity comparable to the remaining term of the Senior Notes to be redeemed that would be used, 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 Senior Notes to be redeemed. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date for any Senior Note, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations or (2) if the
Company obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received. 

  
 2 

 “Primary Treasury Dealer” means a primary U.S. Government Securities dealer
in the United States. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

 “Redemption Price” means the price at which 3.25% Senior Notes may be redeemed pursuant to
Section 401(a) or Section 401(b) hereto or at which 4.60% Senior Notes may be redeemed pursuant to Section 402(a) or Section 402(b) hereto, as applicable. 
 “Reference Treasury Dealer” means (1) each of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., BNP Paribas Securities Corp. and CastleOak

Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each 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) quoted in writing to the Company by that Reference
Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. For purposes of this definition only, “Business Day” means any day that is not a day on which banking institutions in
New York City are authorized or required by law or regulation to close.

means, with respect to each of the Senior Notes that the Company is redeeming pursuant to Section 401 or Section 402 hereto, the remaining scheduled payments of principal and interest that would be due after the applicable Redemption Date
if such Senior Notes were not redeemed. However, if the Redemption Date is not a scheduled Interest Payment Date with respect to such Senior Notes, the amount of the next succeeding scheduled interest payment on such Senior Notes will be reduced by
the amount of interest accrued on such Senior Notes to the Redemption Date. 
 “Senior Notes” means the 3.25%
Senior Notes or the 4.60% Senior Notes, as the context may require.

of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation of the United States of America, and which in the case of (a) and (b) are not callable or redeemable at the option of
the issuer thereof, and shall also include a depository receipt issued by a bank or trust company as custodian with respect to any such U.S. Government Security or a specific payment of interest on or principal of any such U.S. Government Security
held by such custodian for the account of the holder of a depository receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any

of California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 3.25%
Senior Note due June 15, 2023 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing December 15, 2013 at the rate of 3.25% per annum until the principal hereof is paid or made available for payment. 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 3.25% Senior Note due June 15, 2023 (this “Senior Note,” and together with all other 3.25% Senior Notes due
June 15, 2023, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment Date;
provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. 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 Senior Note (or one or more Predecessor Bonds) 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 Senior Notes 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 the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from June 14, 2013 or from the most recent Interest Payment Date to which interest has been paid or duly
provided for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the Maturity Date falls on a day that is not a

  
 A-2

 
Business Day, the payment of principal, premium, if any, and interest may be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after
maturity. 
 Payment of principal of, premium, if any, and interest on Senior Notes shall be made 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. Payments of principal of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be made by wire transfer
of immediately available funds to the Holder of such Global Bond, provided that, in the case of payments of principal and premium, if any, such Global Bond is first surrendered to the Paying Agent. If any of the Senior Notes are no longer
represented by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such Senior Notes to
the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address shall appear in the
Bond Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may designate in writing to
the Trustee at least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS
OF THIS SENIOR NOTE 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 Senior Note shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

 Reverse of Senior Note 

This 3.25% Senior Note due June 15, 2023 is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or
more series under an Amended and Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as heretofore supplemented and as further supplemented by a Nineteenth Supplemental Indenture, dated as of June 14, 2013 (as
so supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called the “Indenture”), between the Company and The Bank of New
York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), 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 description of the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and delivered.
This Senior Note is a Bond within the meaning of the Indenture and is one of the Bonds of the thirty-ninth series designated as the 3.25% Senior Note due June 15, 2023 established by the Company under the Indenture. The acceptance of this
Senior Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to
March 15, 2023 at a Redemption Price equal to the greater of: 
 (i) 100% of the principal amount of the
Senior Notes to be redeemed; or 
 (ii) as determined by the Quotation Agent, the sum of the present values of
the Remaining Scheduled Payments of principal and interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the
Adjusted Treasury Rate, plus 20 basis points, 
 plus, in either of the above cases, accrued and unpaid interest thereon to but not including
the Redemption Date; and (b) at any time on or after March 15, 2023 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon to but not including the Redemption Date. 

Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Senior Notes, or
one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 
 In the case of an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 30 days nor more than 60 days prior to the Redemption Date to each
Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar amount has not been determined as of the date such notice is
being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption 

  
 A-6

 
Price of all Senior Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such
Redemption Date such Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in principal amount may be redeemed in part but only in integral multiples of $1,000. 

In the event of redemption of this Senior Note in part only, a new Senior Note or Senior Notes of like tenor for the unredeemed portion
hereof will be issued in the name of the Holder hereof upon the surrender hereof. 
 As provided in the Indenture and subject to
certain limitations therein set forth, this Senior Note or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and the Company’s entire
indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible
Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient to pay
when due the principal of and premium, if any, and interest on this Senior Note when due. 
 If an Event of Default shall occur
and be continuing, the Trustee or the Holders of not less than 33% in aggregate principal amount of the Outstanding Bonds, considered as one class, may declare the principal amount of all Bonds then Outstanding to be due and payable immediately by
notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that with respect to certain Events of Default relating to bankruptcy, insolvency and similar events, the principal amount of all Bonds then Outstanding
shall be due and payable immediately without further action by the Trustee or the Holders. 
 The Indenture permits, with
certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with
the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding, considered as one class; provided, however, that if there shall be Bonds of more than one series Outstanding under the
Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the
Outstanding Bonds of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Bonds of any series shall have been issued in more than one Tranche and if a proposed supplemental indenture shall
directly affect the rights of the Holders of Bonds of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all Tranches so directly affected,
considered as one class, shall be required; and provided, further, that the Indenture permits the Company and the Trustee to enter into one or more supplemental indentures for certain purposes without the consent of any Holders of Bonds. The
Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Bonds, on behalf of the Holders of all such Bonds, to waive certain past defaults under the Indenture and

  
 A-7

 
their consequences. Any such consent or waiver by the Holder of this Senior Note shall be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior
Note 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 Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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, the Holders of at least 33% in aggregate principal amount of the Bonds 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 at least a
majority in aggregate principal amount of Bonds at the time Outstanding a direction inconsistent with such written 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the
Bond Register, upon surrender of this Senior Note 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 Senior Note are payable, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Bond Registrar, as the case may be, duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more
new Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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. 
 The Company shall not be required
to execute or to provide for the registration of the transfer of or the exchange of (A) any Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior
Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

  
 A-8

 Prior to due presentment of this Senior Note 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 Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such
agent shall be affected by notice to the contrary. 
 This Senior Note shall be governed by, and construed and enforced in
accordance with, the laws of the State of California without regard to the principles of conflicts of laws thereunder, except to the extent that the Trust Indenture Act shall be applicable. 

As provided in the Indenture, no recourse shall be had for the payment of the principal of, premium, if any, or interest with respect to
this Senior Note, or any part thereof, or for any claim based hereon or otherwise in respect hereof, or of the indebtedness represented hereby, or upon any obligation, covenant or agreement under the Indenture, against any incorporator, shareholder,
officer or director, as such, past, present or future, of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional
provision, statute or rule of law or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture and all the Bonds are solely corporate obligations and that any such personal liability is
hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of this Senior Note. 
 All terms used in this Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.

 Reverse of Senior Note 

This 4.60% Senior Note due June 15, 2043 is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or
more series under an Amended and Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as heretofore supplemented and as further supplemented by a Nineteenth Supplemental Indenture, dated as of June 14, 2013 (as
so supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called the “Indenture”), between the Company and The Bank of New
York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), 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 description of the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and delivered.
This Senior Note is a Bond within the meaning of the Indenture and is one of the Bonds of the fortieth series designated as the 4.60% Senior Note due June 15, 2043 established by the Company under the Indenture. The acceptance of this Senior
Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to
December 15, 2042 at a Redemption Price equal to the greater of: 
 (i) 100% of the principal amount of the
Senior Notes to be redeemed; or 
 (ii) as determined by the Quotation Agent, the sum of the present values of
the Remaining Scheduled Payments of principal and interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the
Adjusted Treasury Rate, plus 20 basis points, 
 plus, in either of the above cases, accrued and unpaid interest thereon to but not including
the Redemption Date; and (b) at any time on or after December 15, 2042 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon to but not including the Redemption Date. 

Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Senior Notes, or
one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 
 In the case of an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 30 days nor more than 60 days prior to the Redemption Date to each
Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar amount has not been determined as of the date such notice is
being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption 

  
 B-6

 
Price of all Senior Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such
Redemption Date such Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in principal amount may be redeemed in part but only in integral multiples of $1,000. 

In the event of redemption of this Senior Note in part only, a new Senior Note or Senior Notes of like tenor for the unredeemed portion
hereof will be issued in the name of the Holder hereof upon the surrender hereof. 
 As provided in the Indenture and subject to
certain limitations therein set forth, this Senior Note or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and the Company’s entire
indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible
Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient to pay
when due the principal of and premium, if any, and interest on this Senior Note when due. 
 If an Event of Default shall occur
and be continuing, the Trustee or the Holders of not less than 33% in aggregate principal amount of the Outstanding Bonds, considered as one class, may declare the principal amount of all Bonds then Outstanding to be due and payable immediately by
notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that with respect to certain Events of Default relating to bankruptcy, insolvency and similar events, the principal amount of all Bonds then Outstanding
shall be due and payable immediately without further action by the Trustee or the Holders. 
 The Indenture permits, with
certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with
the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding, considered as one class; provided, however, that if there shall be Bonds of more than one series Outstanding under the
Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the
Outstanding Bonds of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Bonds of any series shall have been issued in more than one Tranche and if a proposed supplemental indenture shall
directly affect the rights of the Holders of Bonds of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all Tranches so directly affected,
considered as one class, shall be required; and provided, further, that the Indenture permits the Company and the Trustee to enter into one or more supplemental indentures for certain purposes without the consent of any Holders of Bonds. The
Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Bonds, on behalf of the Holders of all such Bonds, to waive certain past defaults under the Indenture and

their consequences. Any such consent or waiver by the Holder of this Senior Note shall be conclusive and binding upon such Holder and upon all future Holders of this Senior Note and of any Senior
Note 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 Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Senior Note 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, the Holders of at least 33% in aggregate principal amount of the Bonds 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 at least a
majority in aggregate principal amount of Bonds at the time Outstanding a direction inconsistent with such written 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 Senior Note 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 Senior 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 any premium and interest on this Senior Note 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 Senior Note is registrable in the
Bond Register, upon surrender of this Senior Note 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 Senior Note are payable, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Bond Registrar, as the case may be, duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more
new Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Senior Notes 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, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes 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. 
 The Company shall not be required
to execute or to provide for the registration of the transfer of or the exchange of (A) any Senior Note of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Senior

Notes called for redemption, or (B) any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part. 

Prior to due presentment of this Senior Note 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 Senior Note is registered as the owner hereof for all purposes, whether or not this Senior Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 This Senior Note shall be governed by, and construed and enforced in accordance with, the laws of the State of
California without regard to the principles of conflicts of laws thereunder, except to the extent that the Trust Indenture Act shall be applicable. 
 As provided in the Indenture, no recourse shall be had for the payment of the principal of, premium, if any, or interest with respect to this Senior Note, or any part thereof, or for any claim based
hereon or otherwise in respect hereof, or of the indebtedness represented hereby, or upon any obligation, covenant or agreement under the Indenture, against any incorporator, shareholder, officer or director, as such, past, present or future, of the
Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture and all the Bonds are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as
part of the consideration for, the execution of the Indenture and the issuance of this Senior Note. 
 All terms used in this
Senior Note which are not defined herein shall have the meanings assigned to them in the Indenture.
