 (4) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. 
 SECTION 103. Form of Documents Delivered to Trustee. 
 In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that
they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents. 
 Any certificate or opinion of an officer of the Company may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters
upon which his certificate or opinion is based are erroneous. Any such certificate or opinion of counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with
respect to such matters are erroneous. 
 Where any Person is required to make, give or execute two or more applications,
requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 SECTION 104. Acts of Holders; Record Dates. 
 (a) Any
request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise

  

 9 

 
expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument
or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of
the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 
 (c) The Company
may, in the circumstances permitted by the Trust Indenture Act, fix any day as the record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization,
direction, notice, consent, waiver or other action, provided or permitted by this Indenture, or to vote on any action, authorized or permitted to be given, made or taken by Holders of Securities of such series; provided that the Company may
not set a record date for, and the provisions of this paragraph shall not apply to any Person in respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant
to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided
that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. If not set by the Company prior to
the first solicitation of a Holder of Securities of such series made or taken by any Person in respect of any such action, or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the 30th day (or,
if later, the date of the most recent list of Holders required to be provided pursuant to Section 701) prior to such first solicitation or vote, as the case may be. With regard to any record date, only the Holders on such date (or their duly
designated proxies) shall be entitled to give or take, or vote on, the relevant action. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of
such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
  

 10 

 The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to
in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on
such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106. With respect to any record set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may
change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant
series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record dates shall
be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Without limiting the foregoing, any Holder
entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount. 
 (d) The ownership of Securities shall be proved by the
Security Register. 
 (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of
any Security shall bind every future Holder of the same Security and the Holder of every Security 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 Security. 
 SECTION 105.
Notices, Etc., to Trustee and Company. 
 Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  

 11 

 (1) the Trustee by any Holder or by the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Administration, or 
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in
writing to the Trustee by the Company. 
 SECTION 106. Notice to Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 SECTION 107. Conflict with Trust Indenture Act. 
 If any provision hereof limits, qualifies
or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the
Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. 
 SECTION 108. Effect of Headings and Table of Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
 SECTION 109. Successors and Assigns. 
 All covenants and agreements in this Indenture by
the Company shall bind its successors and assigns, whether so expressed or not. 
  

 12 

 SECTION 110. Separability Clause. 
 In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 111. Benefits of
Indenture. 
 Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other
than the parties hereto and their successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 112. Governing Law. 
 This Indenture and the
Securities shall be governed by and construed in accordance with the laws of the State of New York. 
 SECTION 113. Legal
Holidays. 
 In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall
not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu of this
Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. 
 ARTICLE TWO 
 Security Forms 
 SECTION 201. Forms Generally. 
 The Securities of each series and the Trustee’s certificates of authentication shall be in substantially the forms set forth in this
Article or in such other form as shall be established by or pursuant to a Board Resolution or in one or more indentures supplemental hereto, in each case, with such appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or Depositary
therefor or as may, consistently herewith, be determined by the officers executing such Securities, as evidenced by their execution of the Securities. If the form of Securities of any series is established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 303
for the authentication and delivery of such Securities.

 Upon their original issuance, if any, the Rule 144A Securities and the Regulation S
Securities shall be issued in the form of separate Global Securities registered in the name of the Depositary or its nominee and deposited with the Trustee, as custodian for the Depositary, for credit by the Depositary to the respective accounts of
beneficial owners of the Securities represented thereby (or such other accounts as they may direct). The Global Security representing Rule 144A Securities, together with its Successor Securities which are Global Securities other than Regulation S
Global Securities, are collectively herein called the “Restricted Global Security.” The Global Security representing Regulation S Securities, together with its Successor Securities which are Global Securities other than Restricted Global
Securities, are collectively herein called the “Regulation S Global Security.” 
 The definitive Securities shall be
printed, lithographed or engraved or produced by any combination of these methods on steel engraved borders or may be produced in any other manner permitted by the rules of any securities exchange on which the Securities may be listed, all as
determined by the officers executing such Securities, as evidenced by their execution of such Securities. 
 SECTION 202. Form of
Face of Security. 
 [If the Security is a Global Security, insert the legends required by Section 204 of the
Indenture.] 
 [If Restricted Securities, then insert—THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE
EXEMPTION THEREFROM AND IN ANY EVENT MAY BE SOLD OR OTHERWISE TRANSFERRED ONLY IN ACCORDANCE WITH THE INDENTURE, COPIES OF WHICH ARE AVAILABLE FOR INSPECTION AT THE CORPORATE TRUST OFFICE OF THE TRUSTEE IN NEW YORK. 
 EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF
THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. EACH HOLDER OF THIS SECURITY REPRESENTS TO TRANS-ALLEGHENY INTERSTATE LINE COMPANY THAT (a) SUCH HOLDER WILL NOT SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY (WITHOUT THE CONSENT OF
TRANS-ALLEGHENY INTERSTATE LINE COMPANY) OTHER THAN (i) TO A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION COMPLYING WITH RULE 144A UNDER THE SECURITIES ACT, (ii) IN ACCORDANCE WITH RULE 144 UNDER THE SECURITIES ACT, (iii) OUTSIDE
THE UNITED STATES IN A TRANSACTION MEETING THE REQUIREMENTS OF REGULATION S UNDER THE SECURITIES ACT, (iv) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, SUBJECT, IN THE CASE OF CLAUSES (ii), (iii) OR
(iv), TO THE RECEIPT BY TRANS-ALLEGHENY INTERSTATE LINE COMPANY OF AN OPINION OF

  

 14 

 
COUNSEL OR SUCH OTHER EVIDENCE ACCEPTABLE TO TRANS-ALLEGHENY INTERSTATE LINE COMPANY THAT SUCH RESALE, PLEDGE OR TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR
(v) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND THAT (b)THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY OF THE RESALE RESTRICTIONS REFERRED TO HEREIN AND DELIVER TO THE TRANSFEREE (OTHER

 [If Regulation S Securities, then insert—THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER
THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON IN THE ABSENCE OF SUCH
REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION UNDER SUCH LAWS.]

	No.                     	 	$                    

 Trans-Allegheny Interstate Line Company, a corporation duly incorporated under the
laws of Maryland and Virginia (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to
                            , or registered assigns, the principal sum of
                             Dollars on
                             [if the Security is to bear interest prior to Maturity, insert—] and
to pay interest thereon from                      or from the most recent Interest Payment Date to which interest has been paid or duly provided for,
[monthly] [quarterly] [semi-annually on                      and
                     in such year], commencing             , 20    
at the rate of             % per annum, until the principal hereof is paid or made available for payment. [If applicable, then insert—, provided, that, any principal and
premium, and any such installment of interest which is overdue shall bear interest at the rate of             % per annum (to the extent that the payment of such interest shall be legally
enforceable, from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand], [If applicable, then insert—, Provided, however, that if (i) on or
prior to the — day following the original issue date of the Securities, the Company’s registration statement (the “Exchange Registration Statement”) under the Securities Act,
registering a security substantially identical to this Security (except that such Security will not contain terms with respect to the Special Interest payments described below or transfer restrictions) pursuant to an exchange offer (the
“Exchange Offer”) (or, in lieu thereof, a registration statement registering this Security for resale (a “Resale Registration Statement”)) has not become or been declared effective; or (ii) on or prior to the — day following the date of original issue of the Securities, neither the Exchange Registration Statement has been consummated nor, if applicable, the Resale Registration Statement has been declared
effective; or (iii) either the Exchange Registration Statement or, if applicable, the Resale Registration Statement is filed and declared effective (except as specifically permitted therein) but shall thereafter cease to be effective without
being succeeded promptly by an additional registration statement filed and declared effective, in each case (i) through (iii) upon the terms and conditions set forth in the Registration Rights Agreement (each such event referred to in
clauses (i) through (iii), a “Registration Default”), then interest will accrue (in addition to any stated interest on the Securities) (the “Step-Up”) at a rate of 0.25% per annum, determined daily, on the principal
amount of the Securities, for the 90-day period immediately following the occurrence of the Registration Default, which rate shall be increased by 0.25% per annum at the beginning of each subsequent 90-day period (provided that the rate
at which such additional interest accrues shall not exceed 0.50% per annum in the aggregate) and interest shall be payable at such increased rate until such time (the “Step-Down Date”) as no Registration Default is in effect (after
which such interest rate will be restored to its initial rate) or the first date the Securities become freely tradeable under Rule 144(k) of the Securities Act. Interest accruing as a result of the Step-Up (which shall be computed on the basis of a
365-day year and the actual number of days elapsed) is referred to herein as “Special Interest.” Accrued Special Interest, if any, shall be paid semi-annually on
                     and                      in
each year. Any accrued and unpaid interest (including Special Interest) on this Security upon the issuance of an Exchange Security (as defined in the Indenture) in exchange for this Security shall cease to be payable to

  

 16 

 
the Holder hereof but such accrued and unpaid interest (including Special Interest) shall be payable on the next Interest Payment Date for such Exchange Security to the Holder thereof on the
related Regular Record Date.] 
 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
                     or                     
(whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. If any Interest Payment Date falls on a day that is not a Business Day, it shall be postponed to the following Business Day. 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 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.] If
the Security is not to bear interest prior to Maturity, insert—The principal of this Security shall not bear interest except in the case of a default in payment of principal upon acceleration, upon redemption or at Stated Maturity and in such
case the overdue principal and any overdue premium shall bear interest at the rate of ...% per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made
available for payment. Interest on any overdue principal or premium shall be payable on demand. [Any such interest on overdue principal or premium which is not paid on demand shall bear interest at the rate of ...% per annum (to the extent that
the payment of such interest on interest shall be legally enforceable), from the date of such demand until the amount so demanded is paid or made available for payment. Interest on any overdue interest shall be payable on demand.] 
 Payment of the principal of (and premium, if any) and interest on this Security will be made at the office or agency of the Company
maintained for that purpose in                             , 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 [if applicable, insert-: 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.] 
 If this Security is issued in the form of
a Global Security, payments of the principal of (and premium, if any) and interest on this Security shall be made in immediately available funds to the Depositary. If this Security is issued in certificated form, payment of the principal of (and
premium, if any) and interest on this Security will be made at the corporate trust office of the Trustee in The City of New York, New York, maintained for such purpose, and at any other office or agency maintained by the Company for such purpose, 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 to be duly executed under its corporate seal.

 SECTION 203. Form of 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 an Indenture, dated as of             , 2010 (herein called the “Indenture”), between the Company and Union Bank, N.A., as Trustee (herein
called the “Trustee”, which term includes any successor trustee under the Indenture). The Securities will be unlimited in aggregate principal amount. The Securities will initially be issued in an aggregate principal amount of
$            . The Company may, without the consent of the Holders, create and issue additional Securities (the “Additional Securities”) ranking equally with the Securities and
otherwise similar in all respects so that the Additional Securities shall be consolidated and form a single series with the Securities. The Company may not issue Additional Securities if an Event of Default shall occur and be continuing with respect
to the Securities. 
 [If applicable, then insert—: The Company may register a security substantially identical to
this Security (except that such Security will not contain terms with respect to the

  

 18 

 
payment of Special Interest (as described on the face of this Security) or transfer restrictions) pursuant to an Exchange Offer or, in lieu thereof, a Resale Registration Statement.] 

Reference is hereby made to the Indenture and all indentures supplemental thereto 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. 
 [If applicable, then insert—: The Securities of this series are subject to redemption upon not less than 30 nor more than 60
days’ notice by mail, at any time, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Securities to be redeemed, plus accrued interest to the
Redemption Date, or (b) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Securities 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              basis points, plus accrued interest to the
Redemption Date.] 
 [If the Security is subject to redemption of any kind, insert: In the event of redemption of this
Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.] 
 The Securities do not have the benefit of any sinking fund obligations. 
 In the event of a deposit or withdrawal of an interest in this Security (including upon an exchange, transfer, redemption or repurchase of
this Security in part only) effected in accordance with the Applicable Procedures, the Security Registrar, upon receipt of notice of such event from the Depositary’s custodian for this Security, shall make an adjustment on its records to
reflect an increase or decrease of the Outstanding principal amount of this Security resulting from such deposit or withdrawal, as the case may be. 
 If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. 
 [If applicable, then insert: The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of this
Security, or (ii) certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth therein.] 
 [If the Security is an Original Issue Discount Security, insert—If an Event of Default with respect to Securities of this series shall
occur and be continuing, an amount of principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. Such amount shall be equal to—insert formula for determining the
amount. Upon payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal, premium and interest (in each case to the extent that the payment of such interest shall be legally
enforceable), all of the Company’s

  

 19 

 
obligations in respect of the payment of the principal of and premium and interest, if any, on the Securities of this series shall terminate. 
 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 50% in aggregate 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 aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders
of all Securities of each 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 here for 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 the 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 Outstanding Securities 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 principal
of and 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 authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities are issuable only in registered form without coupons in denominations of
$             and any integral multiple thereof. As provided in the Indenture

  

 20 

 
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

 (15) if applicable, that any Securities of the series shall be issuable in whole or in part in the form of one
or more Global Securities and, in such case, the respective Depositaries for such Global Securities, the form of any legend or legends which shall be borne by any such Global Security in addition to or in lieu of that set forth in Section 204
and any circumstances in addition to or in lieu of those set forth in Clause (2) of the last paragraph of Section 305 in which any such Global Security may be exchanged in whole or in part for Securities registered, and any transfer of
such Global Security in whole or in part may be registered, in the name or names of Persons other than the Depositary for such Global Security or a nominee thereof; 
 (16) any other terms of the series, including the covenants to be applicable to Securities of such series (which terms shall

 (18) any other terms of the series (which
terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Section 901(5)). 
 All
Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in
the manner provided, in the Officers’ Certificate referred to above or in any such indenture supplemental hereto. 
 If any
of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or
prior to the delivery of the Officers’ Certificate setting forth the terms of the series. 
 SECTION 302.
Denominations. 
 The Securities of each series shall be issuable only in registered form without
coupons and only in such denominations as shall be specified as contemplated by Section 301. In the absence of any specified denomination with respect to the securities of any series, the Securities of such series shall be issuable only in
denominations of $1,000 and any integral multiple thereof. 
 SECTION 303. Execution, Authentication, Delivery and
Dating. 
 The Securities shall be executed on behalf of the Company by its Chief Executive Officer, its
President, any Vice President, or its Treasurer, under its corporate seal reproduced

  

 24 

 
thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the
Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as
in this Indenture provided and not otherwise. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,

 (1) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by
Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 
 (2) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of
the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general
equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to authenticate such
Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

 Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to
be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph
at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. 
 Each Security shall be dated the date of its authentication. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form
provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such

  

 25 

 
Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture. 
 SECTION 304. Temporary Securities. 
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued
and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
 If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at
the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more like principal amount of definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged the temporary
Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 
 SECTION 305. Registration, Registration of Transfer and Exchange. 
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment
being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities.
The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any Security of a series at an office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like tenor and aggregate principal amount and bearing such restrictive legends
as may be required by this Indenture. 
  

 26 

 At the option of the Holder and subject to the other provisions of this Section 305,
Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of a like tenor and aggregate principal amount and bearing the applicable legends set forth in Section 202, upon surrender of
the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

 If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be
required (i) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of
a notice of redemption of Securities selected for redemption under Section 1104 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 SECTION 306. Mutilated, Destroyed, Lost
and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any
Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona
fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in

  

 27 

 
lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this
Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

 Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall
constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this Section are
exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 SECTION 307. Payment of Interest; Interest Rights Preserved. 
 Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security of any series which is payable, and is punctually paid or duly provided for, on any Interest Payment Date
shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date
(herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in
each case, as provided in Clause (1) or (2) below: 
 (1) The Company may elect to make payment of any
Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment,
and such money when deposited shall be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest

  

 28 

 
which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 
 (2)
The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. 
 (3) Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 SECTION 308. Persons Deemed Owners. 
 Prior to due
presentment of a 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 such Security is registered as the owner of such Security for the purpose of receiving
payment of principal of (and premium, if any) and (subject to Section 307) interest on such Security and for all other purposes whatsoever, whether or not such Security 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. 
 SECTION 309. Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted
by this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with the Trustee’s then customary practice for disposing of securities, unless otherwise directed by a Company Order; provided, however, that the
Trustee shall not be required to destroy any canceled Securities. 
  

 29 

 SECTION 310. Computation of Interest. 
 Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months. 
 SECTION 311. CUSIP Numbers. 

The Company in issuing Securities may use “CUSIP” numbers (if then generally in use) in addition to serial numbers; if so, the
Trustee shall use such CUSIP numbers in addition to serial numbers in notices of redemption and repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such CUSIP
numbers either as printed on the Securities or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Securities, and any such redemption or
repurchase shall not be affected by any defect in or omission of such CUSIP numbers. 
 ARTICLE FOUR 
 Satisfaction and Discharge 
 SECTION 401. Satisfaction and Discharge of Indenture. 
 This Indenture shall cease to be of
further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when 
 (1) either 
 (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company
or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 
 (B) all such Securities not theretofore delivered to the Trustee for cancellation 
 (i) have become due and payable, or 
 (ii) will become due and payable at their Stated Maturity within one year, or

  

 30

Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the
Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust sufficient cash or Government Securities for the purpose an amount sufficient to pay and discharge the
entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the
Stated Maturity or Redemption Date, as the case may be; 
 (C) the Company has paid or caused to be paid all
other sums payable hereunder by the Company; and 
 (D) the Company has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of
the Company to any Authenticating Agent and, if money shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of
Section 1003 shall survive.

be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. 
 ARTICLE FIVE

trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts
generally as they become due, or the taking of corporate action by the Company in furtherance of any such action. 
 SECTION 502.
Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default with respect to Securities
of any series at the time outstanding occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal of all the
Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal shall become immediately due and payable. 
 At any time after such a declaration of acceleration has been made with respect to Securities of any series and before a judgment or decree
for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if 
 (1) the Company has paid or deposited with the
Trustee a sum sufficient to pay 
 (A) all overdue interest on all Securities of that series, 
 (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such
declaration of acceleration and interest thereon at the rate borne by the Securities, 
 (C) to the extent that
payment of such interest is lawful, interest upon overdue interest at the rate borne by the Securities, and 
 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; 
 and 
 (2) all Events of Default with respect to securities of that
series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
  

 33 

 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. 
 The Company covenants that if 
 (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
 (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,

 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the
rate borne by the Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the Holders of securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 SECTION 504. Trustee May File Proofs of Claim. 
 In
case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all
actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments
to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 607. 
 No provision of this Indenture shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  

 34 

 SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered. 
 SECTION 506. Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully
paid: 
 FIRST: To the payment of all amounts due the Trustee under Section 607; and 
 SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities in
respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest,
respectively. 
 SECTION 507. Limitation on Suits. 
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the securities or that series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of
Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
  

 35 

 (5) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being
understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or
to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 
 SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest. 
 Notwithstanding any other provision in this Indenture, the Holder of any Security of any series shall of any series have the right, which is
absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security of that series (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 509. Restoration of Rights and Remedies. 
 If
the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 510. Rights and Remedies
Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to
the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 511. Delay or
Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Securities to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
  

 36 

 SECTION 512. Control by Holders. 
 The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the 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, with respect to the securities of such series, provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture, and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

 SECTION 513. Waiver of Past Defaults. 
 The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all
the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default 
 (1) in the payment of the principal of (or premium, if any) or interest on any Security of such series, or 
 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured,
for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 SECTION 514. Undertaking for Costs. 
 In any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking
or to make such an assessment in any suit instituted by the Company or the Trustee. 
 SECTION 515. Waiver of Stay or Extension
Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the
Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such

  

 37 

 
law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such
law had been enacted. 
 ARTICLE SIX

 The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the
foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if
it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
 SECTION 602. Notice of Defaults.

 (e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such
request or direction; 
 (f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or
by agent or attorney; and

 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof. 
 SECTION 605. May Hold Securities. 
 The Trustee, any Authenticating Agent, any Paying
Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
 SECTION 606.
Money Held in Trust. 
 Money held by the Trustee in trust hereunder need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
  

 39 

 SECTION 607. Compensation and Reimbursement.

of a trustee of an express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 
 (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust,
including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 SECTION 608. Disqualification; Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions
of, the Trust Indenture Act and this Indenture. 
 SECTION 609. Corporate Trustee Required; Eligibility. 

There shall at all times be one (and only one) Trustee hereunder with respect to Securities of each series which may be a Trustee
hereunder for securities of one or more series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports
of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article. 
 SECTION 610. Resignation and Removal;
Appointment of Successor. 
 (a) No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 611. 
  

 40 

 (b) The Trustee may resign at any time with respect to the Securities of one or more series
by giving written notice thereof to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 (c)
The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 
 (d) If at any time: 
 (i) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

 (ii) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written
request therefor by the Company or by any such Holder, or 
 (iii) the Trustee shall become incapable of acting
or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, 
 then, in any such case, (i) the Company by a Board Resolution may remove the Trustee with respect to all
securities, or (ii) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all securities and the appointment of a successor Trustee or Trustees. 
 (e) If the
Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all such series and that at any time there
shall be only one Trustee with respect to the Securities of any particular series). If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any
series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee with respect to the Securities of such series and supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, the Trustee or any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all
others similarly

  

 41 

 
situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the securities of such series. 
 (f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series to all Holders of securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office. 
 SECTION 611. Acceptance of Appointment By
Successor. 
 Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company
and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 
 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such
Trustees co- trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring
Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee
relates. 
  

 42 

 Upon request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor
Trustee had itself authenticated such Securities. 
 SECTION 613. Preferential Collection of Claims Against Company.

 If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the
Trustee shall be subject to any applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
 SECTION 614. Appointment of Authenticating Agent. 
 The
Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a
corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be

  

 43 

 
deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

 Supplemental Indentures 
 SECTION 901. Supplemental Indentures Without Consent of Holders. 
 Without the consent of any Holders, the Company, when authorized by a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in

 (1) to evidence the succession of another
Person to the Company and the assumption by any such successor of the covenants of the Company herein and in the Securities; or 
 (2) to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if such covenants are to be for the benefit of less than all series of Securities, stating

 (3) to secure the Securities; or 
 (4) to add any additional Events of Default for the benefit of the Holders of all or any series of Securities (and if such
additional Events of Default are to be for the benefit of less than all series of Securities, stating that such additional Events of Default are expressly being included solely for the benefit of such series); or 
 (5) to add to or change any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate
the issuance of Securities in bearer form, registrable or not registrable as to principal, and with or without interest coupons, or to permit or facilitate the issuance of Securities in uncertificated form; or 
 (6) to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Securities,
provided that any such addition, change or elimination (A) shall neither (i) apply to any Security of any series created prior to the

  

 46

 (7) to establish the form
or terms of Securities of any series as permitted by Sections 201 and 301; or 
 (8) to evidence and provide for
the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, pursuant to the requirements of Section 611; or 
 (9) to
cure any ambiguity, to correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Indenture which shall not be
inconsistent with the provisions of this Indenture, provided that such action pursuant to this Clause (9) shall not adversely affect the interests of the Holders in any material respect. 
 SECTION 902. Supplemental Indentures with Consent of Holders. 
 With the consent of the Holders of not less than 50% in principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby, 
 (1) change the Stated Maturity of the principal of, or any installment of interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or change the
place of payment where, or the coin or currency in which, any Security or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the
case of redemption, on or after the Redemption Date), or 
 (2) reduce the percentage in principal amount of the
Outstanding Securities of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture, or 
 (3) modify any of the provisions
of this Section or Section 513 except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby.

  

 47 

 A supplemental indenture which changes or eliminates any covenant or other provision of this
Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be
deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 
 It shall not be
necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. 
 SECTION 903. Execution of Supplemental Indentures. 
 In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall
not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 SECTION 904. Effect of Supplemental Indentures.

of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 
  

 48 

 ARTICLE TEN 
 Covenants 
 SECTION 1001. Payment of Principal, Premium
and Interest. 
 The Company covenants and agrees for the benefit of each series of Securities that it will duly
and punctually pay the principal of (and premium, if any) and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. 
 SECTION 1002. Maintenance of Office or Agency. 
 The
Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fall to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may also from time to time designate one or more other offices or agencies (in or outside The City of New York, New York) where
the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of
any change in the location of any such other office or agency. 
 SECTION 1003. Money for Security Payments to Be Held in
Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to any series of Securities,
it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of
(and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act. 
  

 49 

 The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act
applicable to it as a Paying Agent and (ii) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the
written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as such. 
 The Company
may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, New York
notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

SECTION 1004. Statement by Officers as to Default. 
 The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an
Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 SECTION 1005. Existence. 
 Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory)

  

 50 

 
and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. 
 SECTION 1006. Maintenance of Properties. 
 The Company
will cause all properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all
times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the
conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders. 
 SECTION 1007.
Payment of Taxes and Other Claims. 
 The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and
(2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge
or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 
 SECTION 1008. Restrictions on Certain Liens. 
 The
Company will not, and will not permit any Subsidiary to, issue, assume, guarantee or permit to exist any Indebtedness secured by any lien on any property of the Company or a Subsidiary, whether owned on the date that the Securities of any series are
issued or thereafter acquired, without in any such case effectively securing the Outstanding Securities of such series (together with, if the Company shall so determine, any other Indebtedness of or guaranteed by the Company ranking equally with the
Securities) equally and ratably with such Indebtedness (but only so long as such Indebtedness is so secured); provided, however, that the foregoing restriction shall not apply to the following permitted liens: 
 (i) pledges or deposits in the ordinary course of business, as well as those related to financial or other hedging
obligations, and in connection with bids, tenders, contracts or statutory obligations or to secure surety or performance bonds; 
 (ii) liens imposed by law, such as carriers’, warehousemen’s and mechanics’ liens, arising in the ordinary course of business; 
 (iii) liens for property taxes being contested in good faith; 
  

 51 

 (iv) minor encumbrances, easements or reservations which do not in the
aggregate materially adversely affect the value of the properties or impair their use; 
 (v) liens on any
property existing at the time of acquisition thereof (which liens may also extend to subsequent repairs, alterations and improvements to such property); 
 (vi) liens on property existing at the time of acquisition thereof by the Company or a Subsidiary, or to secure any indebtedness incurred by the Company or a Subsidiary prior to, at the time of, or within
270 days after the later of the acquisition, the completion of construction (including any improvements on any existing property) or the commencement of commercial operation of the property, which indebtedness is incurred for the purpose of
financing all or any part of the purchase price or construction or improvements; provided, however, that in the case of any such acquisition, construction or improvement the lien shall not apply to any property previously owned by the
Company or a Subsidiary; 
 (vii) liens, if any, in existence on the date that the Securities are issued;

 (viii) mortgages securing obligations issued by a state, territory or possession of the United States, or any
political subdivision of any of the foregoing or the District of Columbia, to finance the acquisition or construction of property, and on which the interest is not, in the opinion of tax counsel of recognized standing or in accordance with a ruling
issued by the Internal Revenue Service, includible in gross income of the holder by reason of Section 103(a)(1) of the Internal Revenue Code (or any successor to such provision) as in effect at the time of the issuance of such obligations;

 (ix) other liens to secure Indebtedness so long as the amount of outstanding Indebtedness secured by liens
pursuant to this clause (ix) does not exceed 30% of the Company’s Tangible Assets; 
 (x) liens to
secure interim construction financing for new projects undertaken to improve the transmission system, so long as (a) the amount of outstanding Indebtedness secured by liens pursuant to this clause (x), together with outstanding Indebtedness
secured by liens pursuant to clause (ix) above, does not exceed 40% of the Company’s Tangible Assets and (b) such liens under this clause (x) are discharged not later than 90 days following the date that such new projects are
placed into service; and 
 (xi) liens granted in connection with extending, renewing, replacing or refinancing
any of the Indebtedness (so long as there is no increase in the principal amount of the Indebtedness) described in the foregoing clauses (v) through (x) above. 
 In the event that the Company shall propose to pledge, mortgage or hypothecate any property, other than as permitted by clauses (i) through (xi) of the previous paragraph, the Company shall
(prior thereto) give written notice thereof to the Trustee, who shall give notice to the Holders, and the Company shall, prior to or simultaneously with such pledge, mortgage or hypothecation, effectively secure all the Securities equally and
ratably with such Indebtedness. 
  

 52 

 SECTION 1009. Limitation on Sale/Leaseback Transactions. 
 The Company shall not, and shall not permit any Subsidiary to, directly or indirectly, enter into any Sale/Leaseback Transaction unless:

 (i) the Sale/Leaseback Transaction is entered into prior to, concurrently with or within 270 days after the
acquisition, the completion of construction (including any improvements on an existing property) or the commencement of commercial operations of the property; or 
 (ii) the Company or any Subsidiary could otherwise grant a lien on the property as a permitted lien described in
Section 1008. In determining whether the Company or a Subsidiary could have granted a lien on a property the subject of a Sale/Leaseback Transaction pursuant to Section 1008(ix), the amount of Indebtedness being secured shall be deemed to
be equal to the amount capitalized, under generally accepted accounting principles, in respect of the lease involved in such Sale/Leaseback transaction. 
 ARTICLE ELEVEN 
 Redemption of Securities 
 SECTION 1101. Applicability of Article. 
 Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for
such Securities) in accordance with this Article. 
 SECTION 1102. Election to Redeem; Notice to Trustee.

 The election of the Company to redeem any Securities pursuant to Section 1101 shall be evidenced by a Board
Resolution or in another manner as contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor
of the Securities to be redeemed. 
 In the case of any redemption of Securities prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
 SECTION 1103. Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single security), the particular Securities to be redeemed shall be selected not more

  

 53 

 
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized
denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security),
the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with
the preceding sentence. 
 The Trustee shall promptly notify the Company and each Security Registrar in writing of the
Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
 The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of
any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall
relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. 
 SECTION 1104. Notice of Redemption. 
 Notice of
redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. 

All notices of redemption shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price, 
 (3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of
partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed, 
 (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and that interest thereon will cease to accrue on and after said date, 
 (5) the place or places where each such Security are to be surrendered for payment of the Redemption Price, 
  

 54 

 (6) that in the case that a Security is only redeemed in part, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities in an aggregate amount equal to the unredeemed portion of the Security, 
 (7) the aggregate principal amount of Securities being redeemed, and 
 (8) the CUSIP number or numbers of the Securities being redeemed. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
request, by the Trustee in the name and at the expense of the Company. 
 SECTION 1105. Deposit of Redemption Price.

 Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on,
all the Securities which are to be redeemed on that date. 
 SECTION 1106. Securities Payable on Redemption Date. 

 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become
due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise
specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the provisions of Section 307. 
 If any
Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. 
 SECTION 1107. Securities Redeemed in Part. 
 Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to

  

 55 

 
and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Global Security is so surrendered, such new Security shall also be a Global Security. 

ARTICLE TWELVE 
 Defeasance and Covenant Defeasance 
 SECTION 1201. Company’s Option to Effect Defeasance or Covenant
Defeasance. 
 The Company may elect, at its option at any time, to have Section 1202 or Section 1203
applied to any Securities of any series of Securities, as the case may be, designated pursuant to Section 301 as being defeasible pursuant to such Section 1202 or 1203, in accordance with any applicable requirements provided pursuant to
Section 301 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. 

SECTION 1202. Defeasance and Discharge. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged
from its obligations, with respect to the Securities on and after the date the conditions set forth in Section 1204 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the Securities and to have satisfied all its other obligations under the Securities and this Indenture (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of the Securities to receive, solely from the trust fund described in
Section 1204 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, (2) the Company’s obligations with respect to such Securities
under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise its option to have this
Section applied to the Securities notwithstanding the prior exercise of its option to have Section 1203 applied to the Securities. 
 SECTION 1203. Covenant Defeasance. 
 Upon the Company’s exercise of its option (if
any) to have this Section applied to the Securities or any series of Securities, as the case may be, (1) the Company shall be released from any term, provision or condition provided in pursuant to Article Eight and Sections 1006 and 1007, and
any covenants provided pursuant to Section 901(2) for the benefit of the Holders of such Securities and (2) the occurrence of any event specified in Section 501(3) shall be deemed not to be or result in an Event of Default on and
after the date the conditions set forth in Section 1204 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to the Securities, the Company may omit to comply
with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 501(3)) whether

  

 56 

 
directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in
any other document, but the remainder of this Indenture shall be unaffected thereby. 
 SECTION 1204. Conditions to Defeasance or
Covenant Defeasance. 
 The following shall be the conditions to the application of Section 1202 or
Section 1203 to any Securities or any series of Securities, as the case may be: 
 (1) The Company shall
irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of the
Securities, (A) money in an amount, or (B) Government Securities which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of
any payment, money in an amount, or (C) a combination thereof; in each case sufficient to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium
and interest on the Securities on the Stated Maturity, in accordance with the terms of this Indenture and the Securities. 
 (2) In the event of an election to have Section 1202 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel
stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable federal income tax law, in either
case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of the Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be
effected with respect to the Securities and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 
 (3) In the event of an election to have Section 1203 apply to any Securities or any series of Securities, as the case
may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Securities will not recognize gain or loss for federal income tax purposes as a result of the deposit and Covenant Defeasance to be
effected with respect to the Securities and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur. 
 (4) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the
Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 501(4) and 501(5), at any time on or prior to the 91st day after the date of such deposit (it being understood that
this condition shall not be deemed satisfied until after such 91st day). 
  

 57 

 (5) Such Defeasance or Covenant Defeasance shall not cause the Trustee to
have a conflicting interest within the meaning of the Trust Indenture (assuming all Securities are in default within the meaning of such Act). 
 (6) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is
bound. 
 (7) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit
constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder. 
 (8) The Company shall deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Company with the intent of preferring the Holders of the Securities over the other creditors of the Company, or with the intent of defeating, hindering, delaying or defaulting creditors of the Company or others. 
 (9) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of
Counsel may be subject to customary assumptions and exclusions), each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
 SECTION 1205. Deposited Money and Government Securities to Be Held in Trust; Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 1003, all money and Government Securities (including the proceeds thereof)
deposited with the Trustee pursuant to Section 1204 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of any Securities and this Indenture, to the payment, either directly or
through any such Paying Agent as the Trustee may determine, to the Holders of the Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from
other funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1204 or the principal and interest received in respect thereof. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Securities held by it as provided
in Section 1204 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof
which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to any Securities. 
  

 58 

 SECTION 1206. Reinstatement. 
 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of
any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and any Securities shall be revived and reinstated as though no deposit had
occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1205 with respect to any Securities in accordance with this
Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any)
of the Holders of such Securities to receive such payment from the money so held in trust.

 RECITALS 
 WHEREAS, the Company and the Trustee executed and delivered an Indenture, dated as of January 25, 2010 (the
“Indenture”), to provide for the issuance from time to time of its unsecured debentures, notes or other evidences of indebtedness; 
 WHEREAS, capitalized terms used herein and not otherwise defined have the meanings assigned to such terms in the Indenture; 
 WHEREAS, pursuant to a Board Resolution, the Company has authorized the issuance of $450,000,000 of its 4.00% Notes due 2015 (the
“Notes”); 
 WHEREAS, the Company desires to establish the terms of the Notes in accordance with
Section 301 of the Indenture and to establish the form of the Notes in accordance with Section 201 of the Indenture; 
 WHEREAS, the Company and the Trustee have each duly authorized the execution and delivery of this Supplemental Indenture to provide for the issuance of the Notes as in this Supplemental Indenture provided; and

with its terms have been done; 
 NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE WITNESSETH: 
 For and in consideration of the premises and the purchase of the Notes by the Holders thereof, it is mutually agreed, for the equal and
proportionate benefit of all Holders of the Notes, as follows: 
 SECTION 1. Terms of the Notes. The following terms
relating to the Notes are hereby established: 
 (1) The Notes shall constitute a series of Securities having the
title “4.00% Notes due 2015”. 

 (2) The aggregate principal amount of the Notes that may be authenticated
and delivered under the Indenture (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of the series pursuant to Section 304, 305, 306, 906 or 1108 of the
Indenture) shall initially be limited to $450,000,000. The Company may, without the consent of the Holders, create and issue additional Notes (the “Additional Notes”) ranking equally with the Notes and otherwise similar in all
respects so that the Additional Notes shall be consolidated and form a single series with the Notes. The Company may not issue Additional Notes if an Event of Default shall occur and be continuing with respect to the Notes. 
 (3) Interest on any Note shall be payable only to the Person in whose name that Note (or one or more predecessor Notes
thereof) is registered at the close of business on the Regular Record Date for such interest. 
 (4) The entire
outstanding principal of the Notes shall be payable on January 15, 2015, which date shall be the Stated Maturity for the payment of principal on the Notes. 
 (5) The rate at which the Notes shall bear interest shall be 4.00% per annum; the date from which interest shall accrue
on the Notes shall be the date hereof; the Interest Payment Dates for the Notes on which interest shall be payable shall be January 15 and July 15 in each year, beginning July 15, 2010; the Regular Record Date for the interest payable

months. 
 (6) [Reserved] 
 (7) The Notes may be redeemed at any time at the option of the Company, in whole or in part, at a redemption price (the
“Redemption Price”) equal to the greater of (a) 100% of the principal amount of the Notes to be redeemed, plus accrued interest to the Redemption Date, or (b) as determined by the Quotation Agent, the sum of the present
values of the remaining scheduled payments of principal and interest on the 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 25 basis points, plus accrued and unpaid interest to the Redemption Date. 
 If
notice has been given as provided in the Indenture and immediately available funds for the redemption of any Notes (or any portion thereof) called for redemption shall have been delivered to the Paying Agent not later than 11:00 A.M. New York Time
on the Redemption Date referred to in such notice, such Notes (or any portion thereof) shall cease to bear interest on the date fixed for such redemption specified in such notice and the only right of the Holders of the Notes shall be to receive
payment of the Redemption Price with respect to such Notes or portion thereof so redeemed. 
  

 2 

 Notice of any optional redemption of any Notes (or any portion thereof)
shall be given to Holders at their addresses, as shown in the security register for the Notes, not more than 60 nor less than 30 days prior to the date fixed for redemption. The notice of redemption shall specify, among other items, which Notes
shall be redeemed, the Redemption Date, the Redemption Price, and the principal amount of the Notes held by such Holder to be redeemed. 
 The Company shall notify the Trustee at least 30 days prior to giving notice of redemption (or such shorter period as is satisfactory to the Trustee) of the aggregate principal amount of the Notes to be
redeemed and their Redemption Date. If less than all the Notes of a series are to be redeemed, the Trustee shall select, in such manner as it shall deem fair and appropriate, the Notes to be redeemed in whole or in part. 
 In the event of redemption of the outstanding principal amount of the Notes of a series in part only, a new Note (or Notes)
for the amount of the unredeemed portion thereof shall be issued in the name of the Holder(s) thereto, upon cancellation thereof. 
 The following definitions shall apply to the Notes: 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, 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 that 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 Notes that would be
used, at the time of the 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 Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date: (a) the average of the
Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations, or (b) if the Trustee obtains fewer than three Reference Treasury Dealer Quotations, the average
of all Reference Treasury Dealer Quotations so received. 
 “Quotation Agent” means the
Reference Treasury Dealer appointed by the Company. 
 “Rating Agencies” means
Standard & Poor’s Rating Services, Moody’s Investors Service Inc. and Fitch Ratings Ltd.

Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case the Company shall substitute another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer selected by the Company.

  

 3 

 “Reference Treasury Dealer Quotations” means, with respect
to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, 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 Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that Redemption Date. 
 (8) The Notes shall not be redeemable at the option of any Holder thereof under any circumstances. The Notes shall not have the benefit of any sinking fund. 
 (9) The Notes shall be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 (10) The Notes shall be payable on the Stated Maturity in an amount equal to the principal amount thereof plus any unpaid
interest accrued to such Stated Maturity.

the principal of and interest on the Notes shall be made in U.S. Dollars. 
 (12) The Notes shall be issued at
99.626% of their stated principal amount. The entire outstanding principal amount of the Notes payable hereunder in connection therewith shall be payable upon declaration of acceleration of the maturity thereof pursuant to Section 502 of the
Indenture. 
 (13) The principal amount of the Notes, payable at the Stated Maturity, will at all times be
determinable. 
 (14) The Notes established hereunder shall be defeasible pursuant to Article Twelve of the
Indenture at the election of the Company. 
 (15) The Notes shall be offered and sold (A) to Qualified
Institutional Buyers (“QIBs”) in reliance on Rule 144A under the Securities Act and (B) outside the United States in a transaction meeting the requirements of Regulation S under the Securities Act, and shall be issuable in
whole or in part as Global Notes in fully registered form (without coupons) in the form attached as Exhibit A hereto. Holders of definitive Notes and beneficial owners of interests in the Global Notes may exchange such interests for Notes of like
tenor or any authorized form and denomination only in the manner provided in this Supplemental Indenture and in Section 305 of the Indenture. The Depository Trust Company shall be the Depositary with respect to the Global Notes. 
 (16)(A) The Company shall not, and shall not permit any Subsidiary to, engage or invest in any business or activity other
than: 
  

	 	(i)	any business conducted by the Company on the date of this Supplemental Indenture, any reasonable extension thereof, and any additional business reasonably related,
incidental, ancillary or complimentary thereto; or 

  

 4 

	 	(ii)	any other activity permitted (or not prohibited) under the Company’s FERC-approved tariff. 

 (B)(i) If and for so long as any Notes are Outstanding, the Company will make available to the Holders of the Notes the
Company’s audited annual and unaudited quarterly financial statements within 90 days after the end of the period covered by such financial statements either by posting such financial statements on a website (which may be a private website) or
by delivery of electronic or paper copies of such financial statements to the Trustee or other entity that will make such financial statements available to the Holders of the Notes at the Company’s expense. The Company will notify the Trustee
in writing when the financial statements for each period are available and how copies of such financial statements may be obtained by Holders of the Notes, and the Trustee will forward such notice to the Holders of the Notes by mail or electronic
message at the Company’s expense; provided, however, that the failure to notify the Trustee pursuant to this provision will not constitute an Event of Default (as defined in the Indenture). For the avoidance of doubt, “financial
statements” as used in this Supplemental Indenture, will include only a balance sheet, a statement of operations and a statement of cash flows, each prepared in accordance with generally accepted accounting principles (United States or
international, which may be changed), and such financial statements need not satisfy the requirements of Regulation S-X under the Securities Act. 
 (ii) If and for so long as any Notes remain outstanding, the Company will furnish to the Holders of the Notes and to prospective investors, upon their request, the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act. 
 (17) The Notes shall be unsecured obligations of the
Company and shall rank equally with all of the Company’s other unsecured and unsubordinated Indebtedness. 
 (18)(A) The Trustee shall also be the Security Registrar and Paying Agent with respect to the Notes.

under the Securities Act or (ii) outside the United States in a transaction meeting the

  

 5

bound by such restrictions on transfer. If at any time DTC notifies the Company that it is unwilling or unable to continue as Depository for the Global Note or if at any time DTC has ceased to be a clearing agency registered under the Exchange Act
if so required by applicable law or regulation, the Company shall appoint a successor depository with respect to the Global Note and provide notice to the Trustee of such appointment. If (x) a successor depository for such Global Note is not
appointed by the Company within 90 days after the Company receives such notice or becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the beneficial owners representing a
majority in principal amount of the Notes represented by such Global Note advise DTC, with a copy to the Trustee and the Company, to cease acting as depository for such Global Note or (z) the Company, in its sole discretion and subject to the
procedures of DTC, determines at any time that all (but not less than all) Outstanding Notes issued or issuable in the form of Global Note shall no longer be represented by such Global Note and advises the Trustee and DTC of such determination, then
the Company shall execute, and the Trustee shall authenticate and deliver, definitive Notes of like series, rank, tenor and terms in a definitive form in an aggregate principal amount equal to the principal amount of such Global Note and in such
names as the depository shall instruct the Trustee. 
 On or after the earliest date on which such interest may
be so exchanged as described above, the Global Note shall be surrendered for exchange by DTC to the Trustee; provided, however, that no such exchange may occur during a period beginning at the opening of business 15 days before any
selection of Notes to be redeemed and ending on the relevant Redemption Date if the Global Note for which exchange is requested may be among those selected for redemption. If a definitive Note is issued in exchange for any portion of the Global Note
after the close of business at the office or agency where such exchange occurs on (i) a Regular Record Date and before the opening

  

 7 

 
of business at such office or agency on the relevant Interest Payment Date, or (ii) a Special Record Date and before the opening of business at such office or agency on the related proposed
date for payment of interest or Defaulted Interest, as the case may be, such interest will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Definitive Note, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such Global Note is payable in accordance with the provisions of the Indenture. 
 Whenever any Restricted Note is presented or surrendered for registration of transfer or for exchange for a Note registered
in a name other than that of the Holder, such Restricted Note must be accompanied by a transferor’s certificate in the form of Exhibit B hereto confirming that such proposed transfer complies with any restrictions on transfer then
applicable to such Restricted Note. Neither the Registrar nor any transfer agent shall be required to accept for registration of transfer or exchange any Restricted Note unless such Registrar or Transfer Agent is satisfied that the restrictions on
transfer set forth in the Indenture have been complied with. 
 The restrictions imposed by this clause
(18)(D) and clause (18)(C) upon the transferability of any particular Restricted Note shall terminate when such Restricted Note has been (i) sold pursuant to an effective registration statement, (ii) transferred pursuant to Rule
144 under the Securities Act, or any successor provision thereto (“Rule 144”), unless the Holder thereof is an affiliate of the Company within the meaning of Rule 144, or (iii) transferred pursuant to Regulation S. Any
Restricted Note (or portion thereof) as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon surrender of such Restricted Note (or the Restricted Note of which such interest is a
part) for exchange to the Registrar or any transfer agent in accordance with the provisions of the Indenture (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer pursuant to Rule 144, by an opinion of
counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable to the Company, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such Restricted Note
has been made in compliance with Rule 144) be exchanged for a new Note (or an interest in a new Global Note), of like aggregate principal amount, which shall not bear the restrictive legend required by clause (18)(C) above (an
“Unrestricted Note”). The Company shall inform the Trustee of the effective date of any registration statement registering the Notes under the Securities Act. 
 As used in this clause (18)(D), the term “transfer” encompasses any sale, pledge, transfer or other disposition of
any Restricted Note. 
 Upon the Company’s satisfaction that the restrictive legend required by clause
(18)(C) above shall no longer be required in order to maintain compliance with the Securities Act, beneficial interests in a Restricted Note may be automatically exchanged into beneficial interests in an Unrestricted Note without any action
required by or on behalf of the Holder (the “Automatic Exchange”) at any time on or after the date that is the 366th calendar day after (A) with respect to the Notes issued on January 25, 2010 (the

  

 8 

 
“Issue Date”), the Issue Date or (B) with respect to Additional Notes, if any, the issue date of such Additional Notes, or, in each case, if such day is not a Business Day,
on the next succeeding Business Day (the “Automatic Exchange Date”). Upon the Company’s satisfaction that the restrictive legend required by clause (18)(C) above shall no longer be required in order to maintain compliance
with the Securities Act, the Company may (i) provide written notice to the Trustee at least 10 calendar days prior to the Automatic Exchange, instructing the Trustee to direct the Depository to exchange all of the outstanding beneficial
interests in a particular Restricted Note to the Unrestricted Note, which the Company shall have previously otherwise made eligible for exchange with the DTC, (ii) provide prior written notice (the “Automatic Exchange Notice”)
to each Holder at such Holder’s address appearing in the register of Holders at least 10 calendar days prior to the Automatic Exchange (the “Automatic Exchange Notice Date”), which notice must include (w) the Automatic
Exchange Date, (x) the section of the Indenture pursuant to which the Automatic Exchange shall occur, (y) the CUSIP number of the Restricted Note from which such Holder’s beneficial interests will be transferred and the (z) CUSIP
number of the Unrestricted Note into which such Holder’s beneficial interests will be transferred, and (iii) on or prior to the date of the Automatic Exchange, deliver to the Trustee for authentication one or more Unrestricted Notes, duly
executed by the Company, in an aggregate principal amount equal to the aggregate principal amount of Restricted Notes to be exchanged. At the Company’s request on no less than 5 calendar days’ notice, the Trustee shall deliver, in the
Company’s name and at its expense, the Automatic Exchange Notice to each Holder at such Holder’s address appearing in the register of Holders. Notwithstanding anything to the contrary in this clause (18)(D), during the 10 day period
between the Automatic Exchange Notice Date and the Automatic Exchange Date, no transfers or exchanges other than pursuant to this clause (18)(D) shall be permitted without the prior written consent of the Company. As a condition to any
Automatic Exchange, the Company shall provide, and the Trustee shall be entitled to rely upon, an Officers’ Certificate in form reasonably acceptable to the Trustee to the effect that the Automatic Exchange shall be effected in compliance with
the Securities Act and that the restrictions on transfer contained herein and in the restrictive legend required by clause (18)(C) above shall no longer be required in order to maintain compliance with the Securities Act and that the aggregate
principal amount of the particular Restricted Note is to be transferred to the particular Unrestricted Note by adjustment made on the records of the Trustee, as custodian for the Depositary to reflect the Automatic Exchange. Upon such exchange of
beneficial interests pursuant to this clause (18)(D), the aggregate principal amount of the Global Notes shall be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, to reflect the relevant
increase or decrease in the principal amount of such Global Note resulting from the applicable exchange. The Restricted Note from which beneficial interests are transferred pursuant to an Automatic Exchange shall be canceled following the Automatic
Exchange. 
 (E) Payment of the principal of (and premium, if any) and interest on the Notes will be made at the
office or agency of the Company maintained for that purpose in San Francisco, California, 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

  

 9 

 
by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. If the Notes are issued in certificated form to a Holder other than DTC,
payments of principal and interest shall be made by check mailed to such Holder at such Holder’s registered address or, upon written application by a Holder of $1,000,000 or more in aggregate principal amount of Notes to the Trustee in
accordance with Section 105 of the Indenture, by wire transfer of immediately available funds to an account maintained by such Holder with a bank or other financial institution. 
 SECTION 2. Form of Note. The Notes shall be in the form set forth in Exhibit A hereto. 
 SECTION 3. Confirmation of Indenture. The Indenture, as supplemented and amended by this Supplemental Indenture, is in all respects
ratified and confirmed, and the Indenture, this Supplemental Indenture and all indentures supplemental thereto shall be read, taken and construed as one and the same instrument. 
 SECTION 4. Governing Law. This Supplemental Indenture and the Notes shall be governed by and construed in accordance with the law of
the State of New York. 
 SECTION 5. Separability. In case any provision in this Supplemental Indenture shall for any
reason be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 6. Counterparts. This Supplemental Indenture may be executed in any number of counterparts each of which shall be an
original, but such counterparts shall together, constitute but one and the same instrument.

 (Reverse of Security) 
 This Security is one of a duly authorized issue of Securities of the Company designated as its 4.00% Notes due 2015 (the
“Securities”), issued under an Indenture, dated as of January 25, 2010 as supplemented by the First Supplemental Indenture dated as of January 25, 2010 (collectively, the “Indenture”), between the Company
and Union Bank, N.A., as Trustee (the “Trustee”, which term includes any successor trustee under the Indenture). The Securities will be unlimited in aggregate principal amount. The Securities will initially be issued in an aggregate
principal amount of $450,000,000. The Company may, without the consent of the Holders, create and issue additional Securities (the “Additional Securities”) ranking equally with the Securities and otherwise similar in all respects so
that the Additional Securities shall be consolidated and form a single series with the Securities. The Company may not issue Additional Securities if an Event of Default shall occur and be continuing with respect to the Securities. Reference is
hereby made to the Indenture and all indentures supplemental thereto 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. 
 The Securities are subject to redemption upon not
less than 30 nor more than 60 days’ notice by mail, at any time, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Securities to be redeemed, plus
accrued interest to the Redemption Date, or (b) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Securities 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 25 basis points, plus accrued and unpaid interest to the Redemption Date. 
 The Redemption Price will be calculated assuming a 360-day year consisting of twelve 30-day months. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, 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 that 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 Securities that would be used, at the time of the 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 Securities. 
 “Comparable Treasury Price” means, with respect to any Redemption Date: (a) the
average of the Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations, or (b) if the Trustee obtains fewer than three Reference Treasury Dealer
Quotations, the average of all Reference Treasury Dealer Quotations so received. 
  

 17 

 “Quotation Agent” means the Reference Treasury Dealer appointed by the
Company. 
 “Reference Treasury Dealer” means (i) each of Barclays Capital Inc., Credit Suisse Securities
(USA) LLC, and J.P. Morgan Securities Inc. and their respective successors, unless any of them ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case the Company shall
substitute another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, 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 Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that Redemption Date. 
 In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Securities do not have the
benefit of any sinking fund obligations. 
 In the event of a deposit or withdrawal of an interest in this Security (including
upon an exchange, transfer, redemption or repurchase of this Security in part only) effected in accordance with the Applicable Procedures, the Security Registrar, upon receipt of notice of such event from the Depositary’s custodian for this
Security, shall make an adjustment on its records to reflect an increase or decrease of the Outstanding principal amount of this Security resulting from such deposit or withdrawal, as the case may be. 
 If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and
with the effect provided in the Indenture. 
 The Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this Security, or (ii) certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth therein. 
 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 under the Indenture at any time by the Company and the Trustee with the consent of the Holders of 50% in aggregate principal amount of the Securities at the time Outstanding. The
Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, 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. 
  

 18 

 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, the Holders of not less than 25% in principal amount of the Outstanding Securities 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 Outstanding Securities 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 San Francisco, California, 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 authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees. 
 The Securities are issuable only in registered form without
coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities
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.

 Interest (other than Special Interest) on this Security shall be computed on the basis of a 360-day year of twelve 30-day
months. 
  

 19 

 All terms used in this Security which are defined in the Indenture shall have the meanings
assigned to them in the Indenture.
