 ARTICLE 2 
 AMENDMENTS TO THE DEPOSITARY TRUST AGREEMENT 
 Section 2.1. Text of the Amendments. The
following Sections of the Depositary Trust Agreement are hereby amended as follows: 
 (1) Section 4.8(b) of the
Depositary Trust Agreement is hereby amended to read in full as follows: 
 “(b) The Trustee shall provide the Sponsor with such
certifications, supporting documents and other evidence regarding the Internal Control Over Financial Reporting established and maintained by the Trust, and used by the Trustee in connection with its preparation of the financial statements of the
Trust, as may be reasonably necessary in order to enable the Sponsor to prepare and file or furnish to the Commission any certifications regarding such matters which may be required to be included with the Trust’s periodic reports under the
Exchange Act.” 
 (2) Section 5.4 of the Depositary Trust Agreement is hereby amended to read in full as follows:

 “Section 5.4. Resignation or Removal of the Trustee; Appointment of Successor Trustee. 
 (a) The Trustee may at any time resign as Trustee hereunder by written notice of its election so to do, delivered to the Sponsor, and such
resignation shall take effect upon the appointment of a successor Trustee and its acceptance of such appointment as hereinafter provided. 
 (b) The Sponsor may remove the Trustee in its discretion by written notice delivered to the Trustee in the manner provided in Section 7.5 at least 90 days prior to the fifth anniversary of the date of this
Agreement or, thereafter, by written notice delivered to the Trustee at least 90 days prior to the last day of any subsequent three-year period. 
 (c) If at any time the Trustee 
 (i) ceases to be a Qualified Bank, 
 (ii) is in material breach of its obligations under this Agreement and fails to cure such breach within 30 days after receipt of written
notice from the Sponsor or Registered Owners acting on behalf of at least 25% of the outstanding Shares specifying such default and requiring the Trustee to cure such default, or 
 (iii) fails to consent to the implementation of an amendment to the Trust’s initial Internal Control Over Financial Reporting deemed
necessary by the Sponsor and, after consultations with the Sponsor, the Sponsor and the Trustee fail to resolve their differences regarding such proposed amendment, 
 the Sponsor, acting on behalf of the Registered Owners, may remove the Trustee by written notice delivered to the Trustee in the manner
provided in Section 7.5, and such removal shall take effect upon the appointment of a successor Trustee and its acceptance of such appointment as hereinafter provided. 
  

 - 2 - 

 (d) If the Trustee acting hereunder resigns or is removed, the Sponsor, acting on behalf
of the Registered Owners, shall use its reasonable efforts to appoint a successor Trustee, which shall be a Qualified Bank. Every successor Trustee shall execute and deliver to its predecessor and to the Sponsor, acting on behalf of the Registered
Owners, an instrument in writing accepting its appointment hereunder, and thereupon such successor Trustee, without any further act or deed, shall become fully vested with all the rights, powers, duties and obligations of its predecessor; but such
predecessor, nevertheless, upon payment of all sums due it and on the written request of the Sponsor, acting on behalf of the Registered Owners, shall execute and deliver an instrument transferring to such successor all rights and powers of such
predecessor hereunder, shall duly assign, transfer and deliver all right, title and interest in the Trust Property to such successor, and shall deliver to such successor a list of the Registered Owners of all outstanding Shares. The Sponsor or any
such successor Trustee shall promptly mail notice of the appointment of such successor Trustee to the Registered Owners. 
 (e) Any corporation into which the Trustee may be merged, consolidated or converted in a transaction in which the Trustee is not the surviving corporation shall be the successor of the Trustee without the execution or filing of any document
or any further act. During the 90-day period following the effectiveness of a merger, consolidation or conversion described in the preceding sentence, the Sponsor may, by written notice to the Trustee, remove the Trustee and designate a successor
Trustee in compliance with the provisions of subsection (c) above.” 
 (3) A new paragraph “(c)” is added at the end of
Section 5.10, to read as follows: 
 “(c) The policies and procedures comprising the Trust’s initial Internal Control Over
Financial Reporting have been adopted and copies thereof have been delivered to the appropriate officers of the Sponsor and the Trustee. Amendments to such initial Internal Control Over Financial Reporting may be proposed from time to time by the
Sponsor, but such amendments may not be adopted in connection with the preparation of the Trust’s financial statements without the Trustee’s consent (which consent will not be unreasonably withheld or delayed).” 
 ARTICLE 3 
 MISCELLANEOUS

 Section 3.1. Counterparts. This Amendment may be executed in any number of counterparts, each of which shall be deemed an
original and all of such counterparts shall constitute one and the same instrument. Copies of this Amendment shall be filed with the Trustee and shall be open to inspection by any Registered Owner during the Trustee’s business hours.

 Section 3.2. Third-Party Beneficiaries. This Amendment is for the exclusive benefit of the parties hereto, and shall not be
deemed to give any legal or equitable right, remedy or claim whatsoever to any other person. 
 Section 3.3. Severability. In
case any one or more of the provisions contained in this Amendment should be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this Amendment shall in no way be
affected, prejudiced or disturbed thereby.

 Section 3.4. Agent for Service; Submission to Jurisdiction. The Sponsor hereby
(i) irrevocably designates and appoints Barclays Bank PLC, New York Branch, General Counsel’s Office, located at 200 Park Avenue, 4th Floor, New York, New York 10166, in the State of New York, as the Sponsor’s authorized agent
upon which process may be served in any suit or proceeding arising out of or relating to this Amendment, (ii) consents and submits to the jurisdiction of any state or federal court in The City of New York, State of New York, in which any such
suit or proceeding may be instituted, and (iii) agrees that service of process upon said authorized agent shall be deemed in every respect effective service of process upon the Sponsor in any such suit or proceeding. The Sponsor agrees to
deliver, upon the execution and delivery of this Amendment, a written acceptance by such agent of its appointment as such agent. The Sponsor further agrees to take any and all action, including the filing of any and all such documents and
instruments, as may be necessary to continue such designation and appointment in full force and effect for so long as any Shares remain outstanding or this Amendment remains in force. In the event the Sponsor fails to continue such designation and
appointment in full force and effect, the Sponsor hereby waives personal service of process upon it and consents that any such service of process may be made by certified or registered mail, return receipt requested, directed to the Sponsor at its
address last specified for notices hereunder, and service so made shall be deemed completed five (5) days after the same shall have been so mailed. 
 Section 3.5. Governing Law. This Amendment shall be interpreted under, and all rights and duties under this Amendment shall be governed by, the internal substantive laws (but not the choice of law rules)
of the State of New York.

 SECTION 2.4 Authentication and Delivery of 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 having attached thereto appropriate Coupons, if any, executed by the Company to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver
such Securities to or upon the written order of the Company, signed by both (a) its chief executive officer, president or any vice president and (b) by its treasurer or any assistant treasurer, secretary or any assistant secretary without
any further action by the Company. 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 6.1) shall
be fully protected in relying upon: 
 (1) a certified copy of any resolution or resolutions of the Company’s Board of
Directors authorizing the action taken pursuant to the resolution or resolutions delivered under clause (2) below; 
 (2)
a copy of any resolution or resolutions of the Company’s Board of Directors relating to such Series, in each case certified by the secretary or an assistant secretary of the Company; 
  

 14 

 (3) an executed supplemental indenture, if any; 
 (4) an Officers’ Certificate setting forth the form and terms of the Securities of such Series as required pursuant to Sections 2.1
and 2.3, respectively, and prepared in accordance with Section 11.5; 
 (5) at the option of the Company, either an
Opinion of Counsel, prepared in accordance with Section 11.5, or a letter addressed to the Trustee allowing the Trustee to rely on an Opinion of Counsel, substantially to the effect that: 
 (a) the form or forms and terms of such Securities and Coupons, if any have been established by or pursuant to a resolution of the
Company’s Board of Directors or by a supplemental indenture as permitted by Sections 2.1 and 2.3 in conformity with the provisions of this Indenture; 
 (b) such Securities and Coupons, if any have been duly authorized, and, 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 binding obligations of the Company enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization or other laws relating to or affecting the enforcement of
creditors’ rights and by general equitable principles, regardless of whether such enforceability is considered in a proceeding in equity or at law; 
 (c) the execution and delivery by the Company of the Securities and Coupons, if any, and the related supplemental indenture, if any, will not contravene any provisions of applicable law; 
 (d) [RESERVED]; 
 (e) no consent, approval, authorization or order of any court or governmental agency or body in the United States is required for the issuance of the Securities of such Series, except such as have been obtained and such as may be required
under the blue sky laws of any jurisdiction in the United States in connection with the purchase and distribution of the Securities of such Series; 
 (f) neither the issue nor sale of the Securities of such Series will contravene the charter or by-laws of the Company or will conflict with, result in a breach of or constitute a default under the terms of any
indenture or other agreement or instrument material to the Company and its Subsidiaries considered as one enterprise which is known to such counsel and to which the Company or any of its Subsidiaries is a party or is bound, or any order or
regulation known to such counsel to be applicable to the Company or any of its Subsidiaries of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Company or any of its Subsidiaries; and 
  

 15 

 (g) the authentication and delivery of the Securities of such series by the Trustee in
accordance with the directions of the Company so to do, and the Company’s execution and delivery of the Securities of such series, will not violate the terms of this Indenture; 
 provided, however, that in the case of any Series issuable in Tranches, if the Trustee has previously received the documents referred to in Section 2.4(1)-(5) with respect to such Series, the
Trustee shall authenticate and deliver Securities of such Series executed and delivered by the Company for original issuance upon receipt by the Trustee of the applicable Company Notice. 
 The Trustee shall have the right to decline to authenticate and deliver any Securities and Coupons, if any, under this Section if the Trustee, being
advised by counsel, determines that such action may not lawfully be taken by the Company or if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under this Indenture in a manner
not reasonably acceptable to the Trustee. 
 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 2.10, together with a written statement (which need not comply with Section 11.5 and
need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, 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 2.5 Execution of Securities. The Securities shall be signed on
behalf of the Company by both (a) its chief executive officer, president or any vice president and (b) its treasurer, any assistant treasurer, its secretary or any assistant secretary, which may, but need not, be attested. Such signatures
may be the manual or facsimile signatures of the present or any future such officers. The seal of the Company may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Securities. Typographical
and other minor errors or defects in any such reproduction of the seal or any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee. Any Coupons attached to any
Unregistered Security shall be executed on behalf of the Company by the manual or facsimile signature of any such officer of the Company. 
 In case any officer of the Company who shall have signed any of the Securities or Coupons shall cease to be such officer before the Security or Coupon so signed shall be authenticated (in the case of the Securities) and delivered by the
Trustee or disposed of by the Company, such Security or Coupon nevertheless may be authenticated and delivered or disposed of as though the person who signed such Security or Coupon had not ceased to be such officer of the Company; and any Security
or Coupon may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Security or Coupon, shall be the proper officers of the Company, although at the date of the execution and delivery of this Indenture
any such person was not such an officer. 
  

 16 

 SECTION 2.6 Certificate of Authentication. Only such Securities as shall bear thereon a
certificate of authentication substantially in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized signatories, shall be entitled to the benefits of this Indenture or be valid or obligatory for any
purpose. Such certificate by the Trustee upon any Security executed by the Company shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of
this Indenture. 
 The Trustee shall not authenticate or deliver any Unregistered Security until any matured Coupons appertaining thereto
have been detached and canceled, except as otherwise provided or permitted by this Indenture. 
 SECTION 2.7 Denomination and Date of
Securities; Payments of Interest. The Securities shall be issuable in denominations as shall be specified as contemplated by Section 2.3. In the absence of any such specification with respect to the Securities of any Series, the Securities
of such Series shall be issuable in denominations of $1,000 and any multiple thereof, which may be in Dollars or any Foreign Currency, and interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Securities shall be
numbered, lettered, or otherwise distinguished in such manner or in accordance with such plan as the officers of the Company executing the same may determine with the approval of the Trustee as evidenced by the execution and authentication thereof.

 Each Security shall be dated the date of its authentication, shall bear interest from the date and shall be payable on the dates, in each
case, which shall be specified as contemplated by Section 2.3. 
 Interest on any Security which is payable, and is punctually paid or
duly provided for, on any interest payment date shall be paid, in the case of Registered Securities, 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 the payment of such interest and, in the case of Unregistered Securities, upon surrender of the Coupon appertaining thereto in respect of the interest due on such interest payment date. 
 The term “record date” as used with respect to any interest payment date (except for a date for payment of defaulted interest) shall mean the
date specified as such in the terms of the Securities of any particular Series, or, if no such date is so specified, if such interest payment date is the first day of a calendar month, the close of business on the fifteenth day of the next preceding
calendar month or, if such interest payment date is the fifteenth day of a calendar month, the close of business on the first day of such calendar month, whether or not such record date is a Business Day. 
 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 (called
“defaulted interest” for the purpose of this Section) shall forthwith cease to be payable to the Registered Holder on the relevant record date by virtue of his 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 clause (2) below: 
  

 17 

 (1) The Company may elect to make payment of any defaulted interest to the persons in
whose names any such Registered Securities (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, such money when deposited to 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 in respect of Registered Securities of such Series
which shall be not more than 15 nor 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 thereof to be mailed, first class postage prepaid, to each Registered Holder 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 mailed as aforesaid, such
defaulted interest in respect of Registered Securities of such Series shall be paid to the person in whose names such Securities (or their respective predecessor Securities) are registered on such special record date and such defaulted interest
shall no longer be payable pursuant to the following clause (2). 
 (2) The Company may make payment of any defaulted interest
on the Registered Securities of any Series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of that Series 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 payment shall be deemed practicable by the Trustee. 
 Any defaulted interest payable in respect of any Security of any Series which is not a Registered Security shall be payable pursuant to such procedures as may be satisfactory to the Trustee in such manner that there
is no discrimination as between the Holders of Registered Securities and other Securities of the same Series, and notice of the payment date therefor shall be given by the Trustee, in the name and at the expense of the Company, by publication at
least once in a newspaper of general circulation in New York, New York. 
 Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon 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. 
  

 18 

 SECTION 2.8 Registration, Transfer and Exchange. The Company will keep or will cause to be kept at
the office or agency of the Trustee to be maintained for the purpose as provided in Section 3.2 a register or registers in which, subject to such reasonable regulations as it may prescribe, the Company will provide for the registration and
transfer of Registered Securities as is provided in this Article Two. Such register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. At all reasonable times
such register or registers shall be open for inspection by the Trustee. 
 Upon due presentation for registration of transfer of any
Registered Security of any Series at any such office or agency to be maintained for the purpose as provided in Section 3.2, the Company shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a
new Registered Security or Registered Securities of the same Series in authorized denominations for a like aggregate principal amount. 
 At
the option of the Holder thereof, Unregistered Securities of a Series, which by their terms are registerable as to principal and interest, may, to the extent and under the circumstances specified pursuant to Section 2.3, be exchanged for
Registered Securities of such Series, as may be issued by the terms thereof. At the option of the Holder thereof, Registered Securities of a Series, which by their terms provide for the issuance of Unregistered Securities, may, to the extent and
under the circumstances specified pursuant to Section 2.3, be exchanged for Unregistered Securities of such Series. Securities so issued in exchange for other Securities shall be of any authorized denomination and of like principal amount and
maturity date, interest rate or method of determining interest, and shall be issued upon surrender of the Securities for which they are to be exchanged and, in the case of Coupon Securities, together with all unmatured Coupons and matured Coupons in
default appertaining thereto, at the office of the Company provided for in Section 3.2 and upon payment, if the Company shall require, of charges provided therein. Unregistered Securities of any Series issued in exchange for Registered
Securities of such Series between the regular record date for such Registered Security and the next interest payment date will be issued without the Coupon relating to such interest payment date, and Unregistered Securities surrendered in exchange
for Registered Securities between such dates shall be surrendered without the Coupon relating to such interest payment date. 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. Notwithstanding the foregoing, an Unregistered Security will not be delivered in exchange for a Registered Security or Securities unless the Trustee receives a
certificate signed by the person entitled to delivery of such Security or other items or documents fulfilling such conditions as shall be required by regulations of the United States Department of the Treasury, or shall be notified by the Company
that such a certificate shall not be required by such regulations; provided, however, that no such Unregistered Security shall be delivered by the Trustee if the Trustee or such agent shall have, or shall have been notified in writing
by the Company that the Company has, actual knowledge that such certificate is false. 
 Upon presentation for registration of any
Unregistered Securities of any Series which by its terms is registerable as to principal, at the office or agency of the Company to be maintained as provided in Section 3.2, such Security shall be registered as to principal 
  

 19 

 in the name of the Holder thereof and such registration shall be noted on such Security. Any Security so registered shall
be transferable on the registry books of the Company upon presentation of such Security at such office or agency for similar notation thereon, but such Security may be discharged from registration by being in a like manner transferred to bearer,
whereupon transferability by delivery shall be restored. Except as otherwise provided pursuant to Section 2.3 hereof, Unregistered Securities shall continue to be subject to successive registrations and discharges from registration at the
option of the Holders thereof. 
 Unregistered Securities shall be transferable by delivery, except while registered as to principal.
Registration of any Coupon Security shall not effect the transferability by delivery of the Coupons appertaining thereto which shall continue to be payable to bearer and transferable by delivery. 
 All Securities and Coupons issued upon any 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 and Coupons surrendered upon such transfer or exchange. 
 Every
Security presented or surrendered for registration of transfer or 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
Trustee 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 transfer or exchange of Securities, other than
exchanges pursuant to Sections 2.11, 8.5 or 12.2 not involving any transfer. 
 The Company shall not be required (i) to issue, register
the transfer of or exchange any Security during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Securities for redemption under Article Twelve or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except, in the case of any Security to be redeemed in part, the portion thereof not redeemed. 
 SECTION 2.9 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security or Coupon shall become mutilated, defaced or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon the written request of any officer of the Company, the Trustee shall authenticate and deliver, a new Security of the same Series or Coupon, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated or defaced Security or Coupon, or in lieu of and substitution for the Security or Coupon so destroyed, lost or stolen. In every case the applicant for a substitute Security or Coupon shall furnish to the Company and to
the Trustee and to any agent of the Company or the Trustee such security or indemnity as may be required by them to indemnify and defend and to save each of them harmless and, in every case of destruction, loss or theft, evidence to their
satisfaction of the destruction, loss or theft of such Security or Coupon and of the ownership thereof. 
  

 20 

 Upon the issuance of any substitute Security or Coupon, 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. In case any Security or Coupon which has matured or is
about to mature or has been called for redemption in full shall become mutilated or defaced or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Security or Coupon, pay or authorize the payment of the same (without
surrender thereof except in the case of a mutilated or defaced Security or Coupon); provided, however, that interest represented by Coupons shall be payable only upon presentation and surrender of such Coupons at an office or agency of
the Company located outside of the United States, unless otherwise provided pursuant to Section 2.3, if the applicant for such payment shall furnish to the Company and to the Trustee and any agent of the Company or the Trustee such security or
indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee and any agent of the Company or the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Security or Coupon and of the ownership thereof. 
 Every substitute Security of any
Series or Coupon issued pursuant to the provisions of this Section by virtue of the fact that any such Security or Coupon is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Security or Coupon shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with
any and all other Securities of such Series or Coupons duly authenticated and delivered hereunder. All Securities or Coupons shall be held and owned upon the express condition that, to the extent permitted by the law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced, destroyed, lost or stolen Securities or Coupons and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 
 SECTION
2.10 Cancellation of Securities. All Securities surrendered for payment, redemption, registration of transfer or exchange, or for credit against any payment in respect of a sinking or analogous fund and all Coupons surrendered for payment or
exchange, shall, if surrendered to the Company or any agent of the Company or the Trustee, be delivered to the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no Securities or Coupons shall be issued in lieu
thereof, except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of cancelled Securities in accordance with its customary procedures or with the written order of the Company. If the Company shall acquire
any of the Securities and Coupons, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities and Coupons unless and until the same are delivered to the Trustee for cancellation. 

SECTION 2.11 Temporary Securities. Pending the preparation of definitive Securities for any Series, the Company may execute and the Trustee
shall authenticate and deliver temporary Securities for such Series (printed, lithographed, typewritten or otherwise 
  

 21 

 reproduced, in each case in form satisfactory to the Trustee). Temporary Securities of any Series may be issued as
Registered Securities or Unregistered Securities with or without Coupons attached thereto, of any authorized denomination, and substantially in the form of the definitive Securities of such Series but with such omissions, insertions and variations
as may be appropriate for temporary Securities, all as may be determined by the Company with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of this Indenture as may be appropriate. Every temporary
Security shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay the Company shall execute and
shall furnish definitive Securities of such Series and thereupon temporary Securities of such Series may be surrendered in exchange therefore without charge at each office or agency to be maintained by the Company for that purpose pursuant to
Section 3.2, and the Trustee shall authenticate and deliver in exchange for such temporary Securities of such Series a like aggregate principal amount of definitive Securities of the same Series of authorized denominations and, in the case of
Unregistered Securities, having attached thereto any appropriate Coupons. Until so exchanged, the temporary Securities of any Series shall be entitled to the same benefits under this Indenture as definitive Securities of such Series. 
 SECTION 2.12 Currency and Manner of Payments in Respect of Securities. 
 (a) With respect to Registered Securities of any Series with respect to which the Holders of such Securities have not made the election provided for in
paragraph (b) below, the following payment provisions shall apply: 
 (1) Except as provided in subparagraph (a)(2) or in
paragraph (e) below, payment of the principal of any Registered Security will be made at the Place of Payment by delivery of a check in the Currency in which the Security is denominated on the payment date against surrender of such Registered
Security, and any interest on any Registered Security will be paid at the Place of Payment by mailing a check in the Currency in which the Securities were issued to the Person entitled thereto at the address of such Person appearing on the Security
register. 
 (2) Payment of the principal of and interest on such Security may also, subject to applicable laws and
regulations, be made at such other place or places as may be designated by the Company by any appropriate method. 
 (b) With respect to
Registered Securities of any Series, the following payment provisions shall apply, except as otherwise provided in paragraphs (e) and (f) below: 
 (1) The Company’s Board of Directors may provide with respect to any Series of such Securities that Holders shall have the option to receive payments of principal of and interest on such Security in any of the
Currencies which may be designated for such election in such Security (or if no such Currencies are designated, in the Currency in which the Securities of such Series are denominated) by delivering to the Trustee a written election, to be in form
and substance satisfactory to the Trustee, not later than the close of business on the record date immediately preceding the applicable payment date. Such election will remain 
  

 22 

 in effect for such Holder until changed by the Holder by written notice to the Trustee (but any such
change must be made not later than the close of business on the record date immediately preceding the next payment date to be effective for the payment to be made on such payment date and no such change may be made with respect to payments to be
made on any Security with respect to which notice of redemption has been given by the Company pursuant to Article Twelve). Any Holder of any such Security who shall not have delivered any such election to the Trustee not later than the close of
business on the applicable record date will be paid the amount due on the applicable payment date in the relevant Currency as provided in paragraph (a) of this Section 2.12. Payment of principal shall be made on the payment date against
surrender of such Securities. Payment of principal and interest shall be made at the Place of Payment by mailing a check in the applicable currency to the Person entitled thereto at the address of such Person appearing on the Security register.

 (2) Payment of the principal of and interest on such Security may also, subject to applicable laws and regulations, be made
at such other place or places as may be designated by the Company by any appropriate method. 
 (c) Payment of the principal of any
Unregistered Security and of interest on any Coupon Security will be made at such place or places outside the United States as may be designated by the Company by any appropriate method only in the Currency in which the Security is payable (except
as provided in paragraph (e) below) on the payment date against surrender of the Unregistered Security, in the case of payment of principal, or the relevant Coupon, in the case of payment of interest. Except as provided in paragraph
(e) below, payment with respect to Unregistered Securities and Coupons will be made by check, subject to any limitations on the methods of effecting such payment as shall be specified in the terms of the Security established as provided in
Section 2.3 and as shall be required under applicable laws and regulations. Payment of the principal of and interest on Unregistered Securities may also, subject to applicable laws and regulations, be made at such other place or places as may
be designated by the Company by any appropriate method. 
 (d) Not later than the fourth Business Day after the record date for each payment
date, the Trustee will deliver to the Company a written notice specifying, in the Currency in which each Series of the Securities are denominated, the respective aggregate amounts of principal of and interest on the Securities to be made on such
payment date, specifying the amounts so payable in respect of the Registered and the Unregistered Securities and in respect of the Registered Securities as to which the Holders shall have elected to be paid in another Currency as provided in
paragraph (b) above. If the Company’s Board of Directors has provided for the election referred to in paragraph (b) above and if at least one Holder has made such election, then not later than the second Business Day preceding such
record date the Company will deliver to the Trustee an Exchange Rate Officer’s Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. The Dollar or Foreign Currency amount receivable by Holders of
Registered Securities who have elected payment in another Currency as provided in paragraph (b) above shall be determined by the Company on the basis of the applicable Market Exchange Rate in effect on the second Business Day (the
“Valuation Date”) prior to such payment date and set forth in the applicable Exchange Rate Officer’s Certificate. 
  

 23 

 (e) If a Conversion Event occurs with respect to a Foreign Currency in which any of the Securities are
denominated or payable, then with respect to each date for the payment of principal of, premium, if any, and interest on the applicable Foreign Currency denominated Securities occurring after the last date on which the Foreign Currency was so used
(the “Conversion Date”), the Dollar shall be the currency of payment for use on each such payment date. The Dollar amount to be paid by the Company to the Trustee and by the Trustee or any Paying Agent to the Holders of such Securities
with respect to such payment date shall be, in the case of a Foreign Currency, the Dollar Equivalent of the Foreign Currency as determined by the Currency Determination Agent in the manner provided in paragraphs (g) or (h) below.

 (f) If the Holder of a Registered Security elects payment in a specified Currency as provided for by paragraph (b) and a Conversion
Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment would have been made in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which
payment would have been made in the absence of such election, such Holder shall receive payment in Dollars. 
 (g) The “Dollar
Equivalent of the Foreign Currency” shall be determined by the Currency Determination Agent as of each Valuation Date and shall be obtained by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Conversion
Date. 
 (h) For purposes of this Section 2.12 the following terms shall have the following meanings: 
 “Market Exchange Rate” shall mean for any currency the noon Dollar buying rate for that currency for cable transfers quoted in New York City on
the Valuation Date as certified for customs purposes by the Federal Reserve Bank of New York. If such rates are not available for any reason with respect to one or more Currencies for which an exchange rate is required, the Currency Determination
Agent shall use, in its sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York as of the most recent available date, or quotations from one or more major banks in New York City or in the country of
issue of the currency in question, or such other quotations as the Currency Determination Agent shall deem appropriate. Unless otherwise specified by the Currency Determination Agent, if there is more than one market for dealing in any currency by
reason of foreign exchange regulations or otherwise, the market to be used in respect of such currency shall be that upon which a nonresident issuer of securities designated in such currency would purchase such currency in order to make payments in
respect of such securities. 
 All decisions and determinations of the Currency Determination Agent regarding the Dollar Equivalent of the
Foreign Currency and the Market Exchange Rate as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Company, the Trustee for the relevant
series of Securities and all Holders of such Securities. 
  

 24 

 In the event that a Conversion Event has occurred with respect to a Foreign Currency, the Company, after
learning thereof, will immediately give notice thereof to the Trustee (and the Trustee will promptly thereafter give notice in the manner provided in Section 11.4 to the affected Holders) specifying the Conversion Date. 
 The Trustee shall be fully justified and protected in relying on and acting upon the information so received by it from the Company and the Currency
Determination Agent and shall not otherwise have any duty or obligation to determine such information independently. 
 SECTION 2.13
Compliance with Certain Laws and Regulations. If any Unregistered Securities or Coupon Securities are to be issued in any Series of Securities, the Company will use reasonable efforts to provide for arrangements and procedures designed
pursuant to then applicable laws and regulations, if any, to ensure that Unregistered Securities or Coupon Securities are sold or resold, exchanged, transferred and paid only in compliance with such laws and regulations and without adverse
consequences to the Company. 
 SECTION 2.14 CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” or
“ISIN” numbers (if then generally in use), and, if so, the Trustee shall indicate the “CUSIP” or “ISIN” numbers of the Securities in notices of redemption as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” or “ISIN” numbers.

 SECTION 2.15 Securities in Global Form. Unless otherwise provided in or pursuant to this Indenture or any Securities, the
Securities shall be issuable in temporary or permanent global form. If Securities of or within a Series are issuable in whole or in part in global form, any such Security may provide that it shall represent the aggregate amount of Outstanding
Securities of such Series (or such lesser amount as is permitted by the terms thereof) from time to time endorsed thereon and may also provide that the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced
or increased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, or changes in the rights of Holders, of Outstanding Securities represented thereby, shall be made in
such manner and by such Person or Persons as shall be specified therein or in the Company order to be delivered to the Trustee pursuant to Section 2.4 or 2.11. Subject to the provisions of Section 2.4 and, if applicable, Section 2.11,
the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Company order. Any instructions by the Company with respect to
endorsement or deliver or redelivery of a Security in global form shall be in writing but need not comply with Section 11.5 and need not be accompanied by an Opinion of Counsel. 
  

 25 

 The provisions of the last paragraph of Section 2.4 shall apply to any Security in global form if
such Security was never issued and sold by the Company and the Company delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 11.5 and need not be accompanied by an Opinion of
Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last paragraph of Section 2.4. 
 Notwithstanding the provisions of Section 3.1, unless otherwise specified as contemplated by Section 2.4, payment of principal of and interest
on any Security in permanent global form shall be made to the Person or Persons specified in such Security. 
 ARTICLE THREE 
 COVENANTS OF THE ISSUER 
 SECTION 3.1
Payment of Principal and Interest. The Company covenants and agrees for the benefit of each Series of Securities that it will duly and punctually pay or cause to be paid (in the currency in which the Securities of such Series and Coupons, if
any, are payable, except as otherwise provided pursuant to Section 2.3 for the Securities of such Series and except as provided in Section 2.12(b), (e) and (f) hereof) the principal of, and interest on, each of the Securities of
such Series in accordance with the terms of the Securities of such Series, any Coupons appertaining thereto and this Indenture. 
 The
interest on Unregistered Securities shall be payable only upon presentation and surrender of the several Coupons for such interest installments as are evidenced thereby as they severally mature at the office of a Paying Agent outside the United
States. The interest on any temporary Unregistered Security shall be paid, as to any installment of interest evidenced by a Coupon attached thereto, if any, only upon presentation and surrender of such Coupon, and, as to the other installments of
interest, if any, only upon presentation of such Securities for notation thereon of the payment of such interest. 
 SECTION 3.2 Offices
for Payment, etc. So long as any of the Securities remain outstanding, the Company will maintain the following for each Series: an office or agency (a) where the Securities may be presented for payment, (b) where the Securities may be
presented for registration of transfer and for exchange as in this Indenture provided and (c) where notices and demands to or upon the Company in respect of the Securities or of this Indenture may be served. The Company will give to the Trustee
written notice of the location of any such office or agency and of any change of location thereof. In case the Company shall fail to so designate or maintain any such office or agency or shall fail to give such notice of the location or of any
change in the location thereof, presentations and demands may be made and notices may be served at the Corporate Trust Office. Unless otherwise specified pursuant to Section 2.3, the Trustee is appointed Paying Agent and Registrar. 

 

 26 

 So long as any Coupon Securities or Unregistered Securities of any Series remain outstanding, the Company
will (except as specified pursuant to Section 2.3) maintain one or more offices or agencies outside the United States in such city or cities as may be specified elsewhere in this Indenture or as contemplated by Section 2.3, and shall
maintain such office or offices for a period of two years (or any period thereafter for which it is necessary in order to conform to United States tax laws or regulations) after the principal on such Coupon Securities or Unregistered Securities has
become due and payable, with respect to such Series where Coupons appertaining to Securities of such Series or Unregistered Securities of such Series may be surrendered or presented for payment, or surrendered for exchange pursuant to
Section 2.8 and where notices and demands to or upon the Company in respect of Coupons appertaining to Securities of such Series or the Unregistered Securities of such Series or of 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 any such office or agency. If at any time the Company shall fail to maintain such required office or agency or shall fail to furnish the Trustee with the address
thereof, presentations, surrenders, notices and demands in respect of Unregistered Securities may be made or served at the Corporate Trust Office of the Trustee and the corporate trust office of any authenticating agent appointed hereunder, and
presentations, surrenders, notices and demands in respect of Coupons appertaining to Securities of any Series and Unregistered Securities may be made or served at the corporate trust office of the Trustee in the other city or cities referred to
above; and the Company hereby appoints the Trustee and any authenticating agent appointed hereunder its agents to receive all such presentations, surrenders, notices and demands. 
 SECTION 3.3 Appointment to Fill a Vacancy in Office of Trustee. The Company, whenever necessary to avoid or fill a vacancy in the office of
Trustee, will appoint, in the manner provided in Section 6.10, a Trustee, so that there shall at all times be a Trustee with respect to each Series of Securities hereunder. 
 SECTION 3.4 Paying Agents. Whenever the Company shall appoint a Paying Agent other than the Trustee with respect to the Securities of any Series,
it will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such Agent shall agree with the Trustee, subject to the provisions of this Section, 
 (a) that it will hold all sums received by it as such Agent for the payment of the principal of or interest on the Securities of such
Series or Coupons (whether such sums have been paid to it by the Company or by any other obligor on the Securities of such Series or Coupons) in trust for the benefit of the Holders of the Securities of such Series or Coupons or of the Trustee, and
upon the occurrence of an Event of Default and upon the written request of the Trustee, pay over all such sums received by it to the Trustee, 
 (b) that it will give the Trustee notice of any failure by the Company (or by any other obligor on the Securities of such Series) to make any payment of the principal of or interest on the Securities of such Series or
Coupons when the same shall be due and payable, and 
  

 27 

 (c) that it will give the Trustee notice of any change of address of any Holder of which
it is aware. 
 The Company will, on or prior to each due date of the principal of or interest on the Securities of such Series or Coupons,
deposit with the Paying Agent a sum sufficient to pay such principal or interest so becoming due, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action. 
 If the Company shall act as its own Paying Agent with respect to the Securities of any Series or Coupons, it will, on or before each due date of the
principal of or interest on the Securities of such Series or Coupons, set aside, segregate and hold in trust for the benefit of the Holders of the Securities of such Series or Holders of such Coupons a sum sufficient to pay such principal or
interest so becoming due. The Company will promptly notify the Trustee of any failure to take such action. 
 Anything in this Section to the
contrary notwithstanding, the Company may at any time, for the purpose of obtaining a satisfaction and discharge with respect to one or more or all Series of Securities or Coupons hereunder, or for any other reason, pay or cause to be paid to the
Trustee all sums held in trust for any such Series by the Company or any Paying Agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein contained. 
 Anything in this Section to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section is subject to the provisions of
Sections 10.3 and 10.4. 
 SECTION 3.5 Written Statement to Trustee. The Company will deliver to the Trustee for each Series of
Securities on or before a date not more than four months after the end of each of its fiscal years ending after the date hereof during which any Securities are outstanding a written statement, signed by two of its officers (which need not comply
with Section 11.5), stating that in the course of the performance of their duties as officers of the Company they would normally have knowledge of any default by the Company in the performance or fulfillment of any covenant, agreement or
condition contained in this Indenture, stating whether or not they have knowledge of any such default and, if so, specifying each such default of which the signers have knowledge and the nature thereof. 
 SECTION 3.6 Limitation on Liens. The Company will not, nor will it permit any Restricted Subsidiary to, directly or indirectly, issue, assume or
guarantee any indebtedness that is secured by a mortgage, pledge, security interest or other lien or encumbrance (a “Lien”), other than Permitted Liens, upon or with respect to any Principal Property or on the capital stock of any
Restricted Subsidiary unless. 
 (a) the Company secures the Securities equally and ratably with (or prior to) any and all other obligations
and indebtedness secured by that Lien; or 
 (b) the aggregate amount of the consolidated indebtedness of the Company and its Restricted
Subsidiaries that is secured by Liens (other than Permitted Liens) on any Principal Property or on the capital stock of any Restricted Subsidiary, together with all 
  

 28 

 Attributable Debt in respect of Sale and Leaseback Transactions existing at such time (with the exception of Sale and
Leaseback Transactions which are not subject to the limitation set forth in Section 3.7 below), does not at the time exceed the greater of (i) 15% of the Company’s Consolidated Net Tangible Assets, as shown on the latest quarterly
consolidated financial statements of the Company and its Subsidiaries preceding the date of determination and (ii) and $200,000,000. 
 SECTION 3.7 Limitation on Sale and Leaseback Transactions. (a) The Company will not, nor will it permit any Restricted Subsidiary to, enter into any arrangement with any person (other than among the Company and/or its Restricted
Subsidiaries (including any Subsidiary that would become a Restricted Subsidiary upon the consummation of any such sale thereto)) pursuant to which the Company or a Restricted Subsidiary agrees to lease any Principal Property (except for leases for
a term of not more than three years) which has been or is to be sold or transferred more than 180 days after the later of the date (i) on which such Principal Property has been acquired by the Company or a Restricted Subsidiary and
(ii) of completion of construction and commencement of full operation thereof, by the Company or a Restricted Subsidiary to that person (a “Sale and Leaseback Transaction”) unless (1) the net proceeds to the Company or a
Subsidiary from the sale or transfer equal or exceed the fair value (as determined by the Board of Directors of the Company or the affected Restricted Subsidiary, as applicable) of the Principal Property so leased, (2) the Company or the
Restricted Subsidiary could incur indebtedness secured by a Lien on the Principal Property to be leased pursuant to Section 3.6 in an amount equal to the Attributable Debt with respect to the Sale and Leaseback Transaction without equally and
ratably securing the Securities, or (3) the Company or its Restricted Subsidiaries, within 180 days after the effective date of the Sale and Leaseback Transaction, applies an amount equal to the fair value (as determined by the Board of
Directors of the Company or the affected Restricted Subsidiary, as applicable) of the Principal Property so leased to (x) the prepayment or retirement of Funded Debt, which may include the Securities; provided, however, that in lieu of applying
all or any part of such net proceeds or fair market value to such retirement, the Company may at its option (A) deliver to the Trustee Securities previously purchased or otherwise acquired by it or (B) receive credit for Securities
previously redeemed by it, which, in either case, have not previously been applied by the Company in lieu of retiring Funded Debt as required pursuant to this Section 3.7(a) or (y) the acquisition of additional real property. 

(b) A Sale and Leaseback Transaction shall not include any such arrangement for financings of air, water or noise pollution control facilities or
sewage or solid waste disposal facilities or involving industrial development bonds or other securities which are tax-exempt pursuant to Section 103 of the Code (or which receive similar tax treatment under any subsequent amendments thereto or
successor laws thereof). 
 SECTION 3.8 Additional Amounts. If Securities of a Series provide for the payment of additional amounts to
any Holder who is a non-United States Person in respect of any tax, assessment or governmental charge (“Additional Amounts”), the Company will pay to the Holder of any Security of such Series or any Coupon appertaining thereto such
Additional Amounts as may be so provided by Section 2.3. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or interest on, or in 
  

 29 

 respect of, any Security of a Series or payment of any related Coupon or the net proceeds received on the sale or
exchange of a Security of a Series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for by the terms of such Series established pursuant to Section 2.3 to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to such terms and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in
those provisions hereof where such express mention is not made. 
 Except as otherwise specified as contemplated by Section 2.3, if the
Securities of a Series provide for the payment of Additional Amounts, at least 10 days prior to each date of payment of principal or interest on which any Additional Amount shall be payable, the Company will furnish the Trustee and the
Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with a compliance certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of or interest on the Securities of
that Series shall be made to Holders of Securities of that Series or any related Coupons who are non-United States Persons without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that
Series. If any such withholding shall be required, then such compliance certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities of that Series or related Coupons and the Company
will pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this Section or in the event the
Trustee shall not withhold or deduct any sums as a result of the non-receipt of a compliance certificate pursuant to this Section. 
 SECTION
3.9 Calculation of Original Issue Discount. The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual
periods) accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to
time. 
 ARTICLE FOUR 
 SECURITYHOLDERS’ LISTS AND REPORTS BY THE 
 ISSUER AND THE TRUSTEE 
 SECTION 4.1 Company to Furnish Trustee Information as to Names and Addresses of Securityholders. The Company covenants and agrees that it will
furnish or cause to be furnished to the Trustee for the Securities of each Series a list in such form as the Trustee may reasonably require of the names and addresses of the Holders of the Registered Securities of each Series: 
  

 30 

 (a) semiannually and not more than 15 days after each record date for the payment of
interest on such Securities, as hereinabove specified, as of such record date and on dates to be determined pursuant to Section 2.3 for non-interest bearing securities in each year, and 
 (b) at such other times as the Trustee may request in writing, within 30 days after receipt by the Company of any such request such list
to be as of a date not more than 15 days prior to the time such information is furnished, 
 provided that if and so long as the Trustee shall be the
Security registrar for such Series, such list shall not be required to be furnished but in any event the Company shall be required to furnish such information concerning the Holders of Coupon Securities and Unregistered Securities which is known to
it; provided, further, that the Company shall have no obligation to investigate any matter relating to any Holder of an Unregistered Security or any Holder of a Coupon. 
 SECTION 4.2 Preservation and Disclosure of Securityholders’ Lists. (a) The Trustee for the Securities of each Series shall preserve, in as current a form as is reasonably practicable, all information
as to the names and addresses of the Holders of each Series of Securities contained in the most recent list furnished to it as provided in Section 4.1 or maintained by the Trustee in its capacity as Security registrar for such Series, if so
acting. The Trustee may destroy any list furnished to it as provided in Section 4.1 upon receipt of a new list so furnished. 
 (b) In
case three or more Holders of Registered Securities of any Series (hereinafter referred to as “applicants”) apply in writing to the Trustee and furnish to the Trustee reasonable proof that each such applicant has owned a Security for a
period of at least six months preceding the date of such application, and such application states that the applicants desire to communicate with other Holders of Securities of a particular Series (in which case the applicants must all hold
Securities of such Series) or with Holders of all Securities with respect to their rights under this Indenture or under such Securities and such application is accompanied by a copy of the form of proxy or other communication which such applicants
propose to transmit, then the Trustee shall, within five business days after the receipt of such application, at its election, either 
 (i) afford to such applicants access to the information preserved at the time by the Trustee in accordance with the provisions of subsection (a) of this Section 4.2, or 
 (ii) inform such applicants as to the approximate number of Holders of Securities of such Series or all Securities, as the case may be,
whose names and addresses appear in the information preserved at the time by the Trustee, in accordance with the provisions of subsection (a) of this Section, as to the approximate cost of mailing to such Securityholders the form of proxy or
other communication, if any, specified in such application. 
 If the Trustee shall elect not to afford to such applicants access to such
information, the Trustee shall, upon the written request of such applicants, mail to each Securityholder of such Series or all Securities, as the case may be, whose name and address appear in the information preserved at the time by the Trustee in
accordance with the provisions of subsection (a) of this Section, a copy of the 
  

 31 

 form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within five days after such tender, the Trustee shall mail to such applicants and file with the Commission together with
a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of the Holders of Securities of such Series or all Securities, as the case may be, or
could be in violation of applicable law. Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order
refusing to sustain any of such objections or if, after the entry of such order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met, and
shall enter an order so declaring, the Trustee shall mail copies of such material to all such Securityholders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any
obligation or duty to such applicants respecting their application. 
 (c) Each and every Holder of Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the
Holders of Securities in accordance with the provisions of subsection (b) of this Section, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under such subsection (b). 
 SECTION 4.3 Reports by the Company. The Company covenants: 
 (a) to file with the Trustee for the Securities of each Series, within 15 days after the Company is required to file the same with the Commission (giving
effect to any extensions thereof), copies of the annual reports and of the information, documents, and other reports (or copies of such portions of any of the foregoing as the Commissioner may from time to time by rules and regulations prescribe)
which the Company may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, or if the Company is not required to file information, documents, or reports pursuant to either

 (d) to furnish
to the Trustee, not less often than annually, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer of the Company as to his or her knowledge of the Company’s compliance with all

 Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not

SECURITYHOLDERS 
 ON EVENT OF DEFAULT 
 SECTION 5.1 Event of Default Defined; Acceleration of Maturity; Waiver of Default. In case one or more of the following Events of Default (unless it is either inapplicable to a particular Series or it is specifically deleted from or
modified in the instrument establishing such Series and the form of Security for such Series) shall have occurred and be continuing with respect to any Series of Securities, that is to say: 
  

 33 

 (a) default in the payment of any installment of interest upon any Security of such Series as and when
the same shall become due and payable, and continuance of such default for a period of 30 days; or

principal of, or any premium on, the Securities of such Series as and when the same shall become due and payable either at maturity, upon redemption (for any sinking fund payment or otherwise), by declaration or otherwise; or 
 (c) failure on the part of the Company duly to observe or perform any other of the covenants or agreements on the part of the Company in the Securities
of such Series, or in this Indenture contained and relating to such Series, for a period of 60 days after the date on which written notice specifying such failure and requiring the Company to remedy the same and stating that such notice is a
“Notice of Default” hereunder shall have been given by registered or certified mail to the Company by the Trustee for the Securities of such Series, or to the Company and the Trustee by the Holders of at least twenty-five percent in
aggregate principal amount at maturity of the Securities of such Series at the time outstanding; or 
 (d) a default occurs under any debt of
the Company having an outstanding principal amount in excess of $50,000,000 in the aggregate which, as a result thereof, the holder(s) of such debt have declared such debt to be due prior to its stated maturity date, or the Company is required to
repurchase or redeem such debt prior to its stated maturity and, in either case, such debt has not been discharged in full or such acceleration or redemption has not been rescinded or annulled within 30 days of the effectiveness thereof; or

 (e) the Company shall make an assignment for the benefit of creditors, or shall file a petition in bankruptcy; or the Company shall be
adjudicated insolvent or bankrupt, or shall petition or shall apply to any court having jurisdiction in the premises for the appointment of a receiver, trustee, liquidator or sequestrator of, or for, the Company or any substantial portion of the
property of the Company; or the Company shall commence any proceeding relating to the Company or any substantial portion of the property of the Company under any insolvency, reorganization, arrangement, or readjustment of debt, dissolution,
winding-up, adjustment, composition or liquidation law or statute of any jurisdiction, whether now or hereafter in effect (hereinafter in this subsection (e) called “Proceeding”); or if there shall be commenced against the Company any
Proceeding and an order approving the petition shall be entered, or such Proceeding shall remain undischarged or unstayed for a period of 60 days; or a receiver, trustee, liquidator or sequestrator of, or for, the Company or any substantial portion

receiver, trustee, liquidator or sequestrator of, or for, the Company or any substantial portion of the property of the Company; provided that a resolution or order for winding-up the Company with a view to its consolidation, amalgamation or merger
with another company or the transfer of its assets as a whole, or substantially as a whole, to such other company as provided in Section 9.1 shall not make the rights and remedies herein enforceable under this subsection (e) of
Section 5.1 if such last-mentioned company shall, as a part of such consolidation, amalgamation, merger or transfer, and within 60 days from the passing of the resolution or the date of the order, comply with the conditions to that end stated
in Section 9.1; or 
  

 34 

 (f) any other Event of Default provided in the Supplemental Indenture or resolution of the Company’s
Board of Directors under which such Series of Securities is issued or in the form of Security for such Series; 
 then and in each and every such case (other
than an Event of Default under clause (e) above), so long as such Event of Default with respect to such Series shall not have been remedied or waived, unless the principal of all Securities of such Series shall have already become due and
payable, either the Trustee for such Series or the Holders of not less than twenty-five percent in aggregate principal amount at maturity of the Securities of such Series then Outstanding hereunder, by notice in writing to the Company (and to the
Trustee if given by such Holders), may declare the principal (or, in the case of Original Issue Discount Securities, such principal amount as may be determined in accordance with the terms thereof) of all the Securities of such Series to be due and
payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities of such Series contained to the contrary notwithstanding. With respect to an Event of
Default described under clause (e) above, the principal of all Securities of such Series shall become immediately due and payable without any declaration or other act by the Trustee or the Holders. This provision, however, is subject to the
condition that if at any time after the principal of the Securities of such Series (or, in the case of Original Issue Discount Securities, such principal amount as may be determined in accordance with the terms thereof) shall have been so declared
due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay in the currency in
which the Securities of such Series are payable (except as otherwise provided pursuant to Section 2.3 for the Securities of such Series and except as provided in Section 2.12(b), (e) and (f) hereof) all matured installments of
interest, if any, upon all the Securities of such Series and the principal of any and all Securities of such Series which shall have become due otherwise than by such acceleration (with interest upon such principal and, to the extent that payment of
such interest is enforceable under applicable law, upon overdue installments of interest, at the rate borne by the Securities of such Series (or, in the case of Original Issue Discount Securities, at the yield to maturity) to the date of such
payment or deposit) and in Dollars such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel and all other expenses and liabilities incurred, and all advances made, by the Trustee, its
agents, attorneys and counsel and any and all defaults under this Indenture, other than the nonpayment of the principal of Securities of such Series which shall have become due by such acceleration, shall have been remedied then and in every such
case the Holders of a majority in aggregate principal amount at maturity of the Securities of such Series then Outstanding, by written notice to the Company and to the Trustee for the Securities of such Series, may waive all defaults and rescind and
annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon. 
  

 35 

 SECTION 5.2 Collection of Indebtedness by Trustee; Trustee May Prove Debt. The Company covenants
that (a) in case default shall be made in the payment of any installment of interest on any of the Securities of any Series when such interest shall have become due and payable, and such default shall have continued for a period of 30 days or
(b) in case default shall be made in the payment of all or any part of the principal of any of the Securities of any Series when the same shall have become due and payable, whether upon maturity of the Securities of such Series or upon any
redemption or by declaration or otherwise, then upon demand of the Trustee for the Securities of such Series, the Company will pay to the Trustee for the Securities of such Series for the benefit of the Holders of the Securities of such Series and
the Holders of any Coupons appertaining thereto the whole amount that then shall have become due and payable on all Securities of such Series or such Coupons for principal of or interest, as the case may be (with interest to the date of such payment
upon the overdue principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest at the same rate as the rate of interest specified in the Securities of such Series); and in
addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor Trustee, their respective agents, attorneys and counsel, and any
expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee. 
 Until such demand is made by the
Trustee, the Company may pay the principal of and interest on the Securities of any Series to the persons entitled thereto, whether or not the principal of and interest on the Securities of such Series are overdue. 
 In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee for the Securities of such Series, in its own name and as
trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree,
and may enforce any such judgment or final decree against the Company or other obligor upon such Securities and collect in the manner provided by law out of the property of the Company or other obligor upon such Securities and Coupons, wherever
situated, the moneys adjudged or decreed to be payable. 
 In case there shall be pending proceedings relative to the Company or any other
obligor upon the Securities and Coupons under Title 11 of the United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or its property or such other obligor, or in case of any other comparable judicial proceedings relative to the Company or other obligor
under the Securities of any Series and Coupons, if any, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise: 
  

 36 

 (a) to file and prove a claim or claims for the whole amount of principal (or, if the
Securities of such Series are Original Issue Discount Securities, such portion of the principal amount as may be due and payable with respect to the Securities of such Series pursuant to a declaration in accordance with Section 5.1 hereof) and
interest owing and unpaid in respect of the Securities of any Series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the
Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee,) and of the Securityholders
and the Holders of any Coupons appertaining thereto allowed in any judicial proceedings relative to the Company or other obligor upon all Securities of any Series, or to the creditors or property of the Company or such other obligor, and 

(b) to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts
received with respect to the claims of the Securityholders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the Holders to make payments to the Trustee
for the Securities of such Series, and, in the event that such Trustee shall consent to the making of payments directly to the Securityholders, to pay to such Trustee such amounts as shall be sufficient to cover reasonable compensation to such
Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by such Trustee and each predecessor Trustee and all other amounts due to such Trustee or
any predecessor Trustee pursuant to Section 6.6. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to or vote for or accept or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of any Series or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Securityholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person. 
 All rights of action and of asserting claims under this Indenture, or under any of the Securities or any Coupon appertaining thereto, may be enforced by the Trustee for the Securities of such Series without the
possession of any of the Securities of such Series or any Coupon appertaining thereto or the production thereof at any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Securities and Holders of any Coupons in respect of which such action was taken. 
 In any proceedings
brought by the Trustee for the Securities of such Series (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the 
  

 37 

 Holders of the Securities and Coupons appertaining thereto in respect to which such action was taken, and it shall not be
necessary to make any Holders of such Securities and Coupons appertaining thereto parties to any such proceedings. 
 SECTION 5.3
Application of Proceeds. Any moneys collected by the Trustee for the Securities of such Series pursuant to this Article in respect of the Securities of any Series shall be applied in the following order at the date or dates fixed by such
Trustee and, in case of the distribution of such moneys on account of principal or interest, upon presentation of the several Securities and any Coupons appertaining thereto in respect of which moneys have been collected and stamping (or otherwise
noting) thereon the payment, or issuing Securities of such Series in reduced principal amounts in exchange for the presented Securities of like Series if only partially paid, or upon surrender thereof if fully paid: 
 FIRST: To the payment of costs and expenses applicable to such Series in respect of which moneys have been collected, including reasonable
compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee and all other amounts due to the
Trustee or any predecessor Trustee pursuant to Section 6.6; 
 SECOND: In case the principal of the Securities of such
Series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest on the Securities of such Series in default in the order of the maturity of the installments of such interest, with
interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the same rate as the rate of interest specified in such Securities, such payments to be made ratably to the persons entitled
thereto, without discrimination or preference; 
 THIRD: In case the principal of the Securities of such Series in respect of
which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such Series for principal and interest, with interest upon the overdue
principal, and (to the extent that payment of such interest is permissible by law and that such interest has been collected by the Trustee) upon overdue installments of interest at the same rate as the rate of interest specified in the Securities of
such Series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such Series, then to the payment of such principal and interest without preference or priority of principal over
interest or of interest over principal, or of any installment of interest over any other installment of interest, or of any Security of such Series over any other Security of such Series, ratably to the aggregate of such principal and accrued and
unpaid interest; and 
 FOURTH: To the payment of the remainder, if any, to the Company or any other person lawfully entitled
thereto. 
  

 38 

 SECTION 5.4 Suits for Enforcement. In case an Event of Default has occurred, has not been waived
and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such
rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law. 
 SECTION 5.5 Restoration of Rights on Abandonment of
Proceedings. In case the Trustee for the Securities of any Series shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee, then and in every such case the Company and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Securityholders
shall continue as though no such proceedings had been taken. 
 SECTION 5.6 Limitations on Suits by Securityholders. No Holder of any
Security of any Series or Holder of any Coupon shall have any right by virtue or by availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to
this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of default and of the
continuance thereof, as hereinbefore provided, and unless also the Holders of not less than 25% in aggregate principal amount of the Securities of such Series then Outstanding shall have made written request upon the Trustee to institute such action
or proceedings in its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity, as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 5.9; it
being understood and intended, and being expressly covenanted by the taker and Holder of every Security and by a Holder of each Coupon appertaining thereto with every other taker and Holder of a Security or Holder of any Coupon appertaining thereto
and the Trustee, that no one or more Holders of Securities of any Series or one or more Holders of any Coupons appertaining thereto shall have any right in any manner whatever, by virtue or by availing of any provision of this Indenture to affect,
disturb or prejudice the rights of any other such Holder of Securities or any other Holders of such Coupons, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in
the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities of the applicable Series and all the Holders of Coupons appertaining thereto. For the protection and enforcement of the provisions of this Section,
each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 SECTION 5.7
Unconditional Right of Securityholders to Institute Certain Suits. Notwithstanding any provision in this Indenture and any provision of any Security or Coupon, the right of any Holder of any Security and the right of any Holder of any Coupon

  

 39 

 appertaining thereto to receive payment of the principal of and interest on such Security at the respective rates, in the
respective amount and in the currency therein prescribed on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder. 
 SECTION 5.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default.
Except as provided in Sections 2.9 and 5.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Securityholders 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. 
 No delay or omission of the Trustee or of any
Securityholder to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein;
and, subject to Section 5.6, every power and remedy given by this Indenture or by law to the Trustee, to the Securityholders or to the Holder of any Coupon appertaining thereto may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee, the Securityholders or Holders of any Coupon. 
 SECTION 5.9 Control by Securityholders. The Holders of a
majority in aggregate principal amount of the Securities of each Series affected (with each Series treated as a separate class) at the time Outstanding 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 by this Indenture; provided that such direction shall not be otherwise than in accordance with law and the
provisions of this Indenture and provided further that (subject to the provisions of Section 6.1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action
or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee, or a trust committee of directors or Responsible Officers of the Trustee shall determine that the action or
proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forebearances specified in or pursuant to such direction would be unduly prejudicial to the interests of
Holders of the Securities of all Series or of the Holders of any Coupons appertaining thereto so affected not joining in the giving of said direction, it being understood that (subject to Section 6.1) the Trustee shall have no duty to ascertain
whether or not such actions or forbearances are unduly prejudicial to such Holders. 
 Nothing in this Indenture shall impair the right of
the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders. 
  

 40 

 SECTION 5.10 Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity
of the Securities of any Series as provided in Section 5.1, the Holders of a majority in aggregate principal amount of the Securities of such Series at the time Outstanding may on behalf of the Holders of all the Securities of such Series and
Holders of all Coupons, if any, appertaining thereto waive any past default hereunder or its consequences, except a default in the payment of the principal of or interest on any of the Securities of such Series. In the case of any such waiver, the
Company, the Trustee, the Holders of the Securities of such Series and the Holder of any Coupon appertaining thereto shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon. 
 Upon any such waiver, such default shall cease to exist and be deemed to have been
cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event
of Default or impair any right consequent thereon. 
 SECTION 5.11 Trustee to Give Notice of Default, But May Withhold in Certain
Circumstances. The Trustee shall transmit to the Securityholders of any Series notice in the manner and to the extent provided in Section 11.4, of all defaults which have occurred with respect to such Series, such notice to be transmitted
within 90 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default” or “defaults” for the purposes of this Section being hereby defined to mean any event or
condition which is, or with notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the payment of the principal of or interest on any of the Securities of such Series or any default in the
payment of any sinking fund installment or analogous obligation in respect of any of the Securities of such Series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a
trust committee of directors or trustees or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders of such Series. 
 SECTION 5.12 Right of Court to Require Filing of Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Security
and each Holder of any Coupon, by his acceptance thereof, shall be deemed to have agreed, that any court may in its discretion require, 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, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including
reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Securityholder or group of Securityholders of any Series holding in the aggregate more than 25% in aggregate principal amount of the Securities of such Series, or to any suit instituted
by any Securityholder for the enforcement of the payment of the principal of or interest on any Security on or after the due date expressed in such Security. 
  

 41 

 ARTICLE SIX 
 CONCERNING THE TRUSTEE 
 SECTION 6.1 Duties and Responsibilities of the Trustee; During Default; Prior to
Default. With respect to the Holders of any Series of Securities issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a particular Series and after the curing or waiving of all Events of
Default which may have occurred with respect to such Series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a Series has occurred
(which has not been cured or waived) of which a Responsible Officer has actual knowledge, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
 No provision of this
Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of Default with respect to the Securities of any Series and after the curing or waiving of all
such Events of Default with respect to such Series which may have occurred: 
 (i) the duties and obligations of the Trustee
with respect to the Securities of any Series shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the
absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but in the case of any such statements, certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine
the same to determine whether or not they conform to the requirements of this Indenture; 
 (b) the Trustee shall not be
liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 
  

 42 

 (c) the Trustee shall not be liable with respect to any action taken or omitted to be
taken by it in good faith in accordance with the direction of the Holders pursuant to Section 5.9 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power
conferred upon the Trustee, under this Indenture. 
 None of the provisions contained in this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there shall be reasonable ground for believing that the repayment of such funds or
adequate indemnity against such 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 conditions of this Section 6.1. 
 SECTION 6.2 Certain Rights of the Trustee. Subject to Section 6.1: 
 (a) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, Officers’
Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon, security or other paper or document believed by it to be genuine and to have been signed or presented by
the proper party or parties; 
 (b) any request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Company’s Board of Directors may be evidenced to the Trustee by a copy thereof
certified by the secretary or any assistant secretary of the Company; 
 (c) the Trustee may consult with counsel of its
selection and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of
Counsel; 
 (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this
Indenture at the request, order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities which might be incurred therein or thereby; 
 (e) the Trustee shall not be liable for any action
taken or omitted by it in good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture; 
  

 43 

 (f) prior to the occurrence of any Event of Default hereunder and after the curing or
waiving of all Events of Default, 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, consent, order, approval, appraisal,
bond, debenture, note, coupon, security, or other paper or document unless requested in writing to do so by the Holders of not less than a majority in aggregate principal amount of the Securities of all Series affected then Outstanding; provided
that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such investigation shall be paid by the Company
or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; 
 (g) the Trustee may
execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the part of
any such agent or attorney appointed with due care by it hereunder; 
 (h) the Trustee shall not be deemed to have notice of any Default or
Event of Default (other than any Event of Default under Section 5.1(a) or 5.1(b)) unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of such Default or Event of Default is received by the Trustee
at the Corporate Trust Office of the Trustee; 
  

	 	1.	the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and 

  

	 	2.	the Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take
specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by and person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered
and not superseded. 

 SECTION 6.3 Trustee Not Responsible for Recitals, Disposition of Securities or Application of
Proceeds Thereof. The recitals contained herein and in the Securities, except the Trustee’s certificate of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Securities or the Coupons. The Trustee represents that it is duly authorized to execute and deliver this Indenture and perform its obligations
hereunder. The Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds thereof. 
  

 44 

 SECTION 6.4 Trustee and Agents May Hold Securities; Collections, etc. The Trustee, any Paying
Agent, Security registrar, or any agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities or Coupons with the same rights it would have if it were not the Trustee or such agent and,
subject to Sections 6.8 and 6.13, if operative, may otherwise deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee or such agent. 
 SECTION 6.5 Moneys Held by Trustee. Subject to the provisions of Section 10.4 hereof, all moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Company or
the Trustee shall be under any liability for interest on any moneys received by it hereunder. 
 SECTION 6.6 Compensation and
Indemnification of Trustee and Its Prior Claim. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as shall be agreed in writing between the Company and the Trustee
in Dollars (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request in
Dollars for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its
counsel and of all agents and other persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith. The Company also covenants to indemnify the Trustee and each predecessor Trustee
for, and to hold it harmless against, any and all loss, liability, damage, claim or expense, including taxes (other than taxes based on the income of the Trustee), incurred without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including the reasonable costs and expenses of defending itself against or investigating any claim (whether asserted by the Company, a Holder
or any other Person) of liability in the premises. The obligations of the Company under this Section to compensate and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each predecessor Trustee for reasonable
expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such additional indebtedness shall be a senior claim to that of the Securities upon all
property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities or the Holders of particular Coupons, and the Securities are hereby subordinated to such senior claim.

 When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.1(d), the expenses
(including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law. 

 

 45 

 SECTION 6.7 Right of Trustee to Rely on Officers’ Certificate, etc. Subject to Sections 6.1
and 6.2, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate complying with
Section 11.5 delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it or under the provisions of
this Indenture upon the faith thereof. 
 SECTION 6.8 Disqualification of Trustee; Conflicting Interests. If the Trustee for the
Securities of any Series has or shall acquire any conflicting interest, as defined in the Trust Indenture Act, it shall, within 90 days after ascertaining that it has such conflicting interest, and if the default (as defined in the Trust Indenture
Act) to which such conflicting interest relates has not been cured or waived or otherwise eliminated before the end of such 90-day period, the Trustee shall, either eliminate such conflicting interest or resign in the manner and with the effect
specified in the Trust Indenture Act and this Indenture. 
 SECTION 6.9 Persons Eligible for Appointment as Trustee. The Trustee for
each Series of Securities hereunder shall at all times be a corporation organized and doing business under the laws of the United States of America or of any State or the District of Columbia having a combined capital and surplus of at least
$50,000,000, and which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination by Federal, State or District of Columbia authority and which has a Corporate Trust Office in any State of the
United States of America. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of
this Section, the Trustee shall resign immediately in the manner and with the effect specified in Section 6.10. 
 SECTION 6.10
Resignation and Removal; Appointment of Successor Trustee. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until acceptance of such appointment by the
successor Trustee in accordance with Section 6.11. 
 (b) The Trustee, or any trustee or trustees hereafter appointed, may at any time
resign with respect to one or more or all Series of Securities by giving written notice of resignation to the Company and by mailing notice thereof to the Holders in the manner and to the extent provided in Section 11.4. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee or trustees with respect to the applicable Series by written instrument in duplicate, executed by authority of the Company’s 
  

 46 

 Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee or trustees. If no successor trustee shall have been so appointed with respect to any Series and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning trustee may petition, at the
expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or any Securityholder who has been a bona fide Holder of a Security or Securities of the applicable Series for at least six months may, subject
to the provisions of Section 5.12, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee. 
 (c) In case at any time any of the following shall occur: 
 (i) the Trustee shall fail to comply with the provisions of Section 6.8 with respect to any Series of Securities after written
request therefor by the Company or by any Securityholder who has been a bona fide Holder of a Security or Securities of such Series for at least six months unless the Trustee’s duty to resign is stayed in accordance with the provisions of
Section 310(b) of the Trust Indenture Act; or 
 (ii) the Trustee shall cease to be eligible in accordance with the
provisions of Section 6.9 and shall fail to resign after written request therefor by the Company or by any Securityholder; or 
 (iii) the Trustee shall become incapable of acting with respect to any Series of the Securities, or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator 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, the Company may remove the Trustee with respect to the applicable Series of Securities and appoint a successor trustee for such Series by written instrument, in duplicate, executed by order of the Board of Directors of the Company,
one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 5.12, any Securityholder who has been a bona fide Holder of a Security or Securities of
such Series 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 and the appointment of a successor trustee with respect to such Series. Such
court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (d) The Holders of a majority in aggregate principal amount of the Securities of each Series at the time Outstanding may at any time remove the Trustee with respect to Securities of such Series and appoint a successor trustee with respect
to the Securities of such Series by delivering to the Trustee so removed, to the successor trustee so appointed and to the Company the evidence provided for in Section 7.1 of the action in that regard taken by the Securityholders. 

 

 47 

 If no successor Trustee shall have been appointed with respect to such series within 30 days after the
mailing of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 (e) Any resignation or removal of the Trustee with respect to any Series and any appointment of a successor trustee with respect to such Series pursuant
to any of the provisions of this Section 6.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 6.11. 
 SECTION 6.11 Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 6.10 shall execute and deliver to the Company and to its predecessor Trustee an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee with respect to all or any applicable Series shall become effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations with respect to such Series of its predecessor hereunder, with like effect as if originally named as trustee for such Series hereunder; but, nevertheless, on the written
request of the Company or of the successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 10.4, pay over to the successor trustee all moneys at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and
certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a prior claim upon all property or funds held or collected by such trustee to secure any amounts then
due it pursuant to the provisions of Section 6.6. 
 If a successor trustee is appointed with respect to the Securities of one or more
(but not all) Series, the Company, the predecessor Trustee and each successor trustee with respect to the Securities of any applicable Series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be
deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any Series as to which the predecessor Trustee is not retiring shall continue to be vested in the
predecessor Trustee, and 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 under separate indentures. 
 No successor trustee with respect to any Series of Securities shall accept appointment as provided in this Section 6.11 unless at the time of such
acceptance such successor trustee shall be qualified under the provisions of Section 6.8 and eligible under the provisions of Section 6.9. 
 Upon acceptance of appointment by any successor trustee as provided in this Section 6.11, the Company shall give notice in the manner and to the extent provided in Section 11.4 to the Holders of Securities
of any Series for which such successor trustee is acting 
  

 48 

 as trustee at their last addresses as they shall appear in the Security register. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 6.10. If the Company fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
 SECTION
6.12 Merger, Conversion, Consolidation or Succession to Business of Trustee. 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 that such corporation shall be
qualified under the provisions of Section 6.8 and eligible under the provisions of Section 6.9, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the
Securities of any Series shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver such Securities so authenticated; and, in case at that
time any of the Securities of any Series shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor Trustee hereunder or in the name of the successor Trustee; and in all
such cases such certificates shall have the full force which it is anywhere in the Securities of such Series or in this Indenture provided that the certificate of the Trustee shall have; provided, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Securities of any Series in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
 SECTION 6.13 Preferential Collection of Claims Against the 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 the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
 ARTICLE SEVEN 
 CONCERNING THE SECURITYHOLDERS

 SECTION 7.1 Evidence of Action Taken by Securityholders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Securityholders of any or all Series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Securityholders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such
agent 
  

 49 

 shall be sufficient for any purpose of this Indenture and (subject to Sections 6.1 and 6.2) conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Article. 
 (b) The ownership of Registered Securities shall be proved by the
Security register. 
 (c) The amount of Unregistered Securities held by any Person executing any instrument or writing as a Securityholder,
the numbers of such Unregistered Securities, and the date of his holding the same may be proved by the production of such Securities or by a certificate executed by any trust company, bank, broker or member of a national securities exchange
(wherever situated), as depositary, if such certificate is in form satisfactory to the Trustee, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Unregistered Securities therein
described; or such facts may be proved by the certificate or affidavit of the Person executing such instrument or writing as a Securityholder, if such certificate or affidavit is in form satisfactory to the Trustee. The Trustee and the Company may
assume that such ownership of any Unregistered Security continues until (i) another certificate or affidavit bearing a later date issued in respect of the same Unregistered Security is produced, or (ii) such Unregistered Security is
produced by some other person, or (iii) such Unregistered Security is surrendered in exchange for a Registered Security, or (iv) such Unregistered Security has been cancelled in accordance with Section 2.10. 
 SECTION 7.2 Proof of Execution of Instruments. Subject to Sections 6.1 and 6.2, the execution of any instrument by a Securityholder or his agent
or proxy may be proved in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. 
 SECTION 7.3 Holders to Be Treated as Owners. The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the person in
whose name any Security shall be registered upon the Security register for such Series as the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for
the purpose of receiving payment of or on account of the principal of and interest on such Security and for all other purposes; and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to
the contrary. All such payments so made to any such person, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Security. 
 SECTION 7.4 Securities Owned by Company Deemed Not Outstanding. In determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all Series have concurred in any direction, consent or waiver under this Indenture or whether a quorum is present at a meeting of Holders of Securities, Securities which are owned by the Company or any other obligor
on the Securities with respect to which such determination is being made or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities with
respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any 
  

 50 

 such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver, and for purposes of determining the presence of a quorum, only Securities which a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged
in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the
Securities or any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be
full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Securities, if
any, known by the Company to be owned or held by or for the account of any of the above-described persons; and, subject to Sections 6.1 and 6.2, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the
facts therein set forth and of the fact that all Securities not listed therein are Outstanding for the purpose of any such determination. 
 SECTION 7.5 Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 7.1, of the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all Series, as the case may be, specified in this Indenture in connection with such action, any Holder of a Security the serial number of which is shown by the evidence to be included among the serial numbers of
the Securities the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article, revoke such action so far as concerns such Security. Except as
aforesaid any such action taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange or substitution therefore, irrespective
of whether or not any notation in regard thereto is made upon any such Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Securities of any or all Series, as the case may be, specified in this Indenture
in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders of all the Securities affected by such action. 
 SECTION 7.6 Record Date for Determination of Holders Entitled to Vote. The Company may, in the circumstances permitted by the Trust Indenture Act, set a record date for the purpose of determining the
Securityholders entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted to be given or taken by Securityholders. If not set by the Company
prior to the first solicitation of a Securityholder made 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 4.1) 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 appointed proxies) shall
be entitled to give or take, or vote on, the relevant action.

 ARTICLE EIGHT 
 SUPPLEMENTAL INDENTURES 
 SECTION 8.1 Supplemental Indentures Without Consent of Securityholders. The
Company, when authorized by a resolution of its Board of Directors, and the Trustee for the Securities of any and all Series may from time to time and at any time enter into an indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act of 1939 as in force at the date of the execution thereof), in form satisfactory to such Trustee, for one or more of the following purposes: 
 (a) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Securities of one or more Series any property or
assets; 
 (b) to evidence the succession of another corporation to the Company, or successive successions, and the assumption
by the successor corporation of the covenants, agreements and obligations of the Company pursuant to Article Nine; 
 (c) to
add to the covenants and/or Events of Default of the Company such further covenants, restrictions, conditions, provisions and/or Events of Default as its Board of Directors and the Trustee shall consider to be for the protection of the Holders of
Securities of any or all Series and, if such additional covenants and/or Events of Default are to be for the benefit of less than all the Series of Securities stating that such covenants and/or Events of Default are being added solely for the
benefit of such Series, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default permitting the enforcement of all or any of the several
remedies provided in this Indenture as herein set forth (and if such additional Events of Default are to be for the benefit of less than all Series of the Securities stating that such Events of Default are being added solely for the benefit of such
Series); provided, that in respect of any such additional covenant, restriction, condition, provision and/or Events of Default such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or
longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders
of a majority in aggregate principal amount of the Securities of such Series to waive such an Event of Default; 
 (d) to cure
any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture; or to make such other
provisions in regard to matters or questions arising under this Indenture or under any supplemental indenture as the Company’s Board of Directors may deem necessary or desirable and which shall not materially and adversely affect the interests
of the Holders of the Securities or the Holders of any Coupons; 
  

 52 

 (e) to establish the form or terms of Securities of any Series as permitted by Sections
2.1 and 2.3; or 
 (f) 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 the one Trustee, pursuant to the
requirements of Section 6.11. 
 The Trustee is hereby authorized to join with the Company in the execution of any such supplemental
indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee 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. 
 Any supplemental indenture authorized by the provisions of this Section may be executed without the consent of the Holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 8.2.

 SECTION 8.2 Supplemental Indentures With Consent of Securityholders. With the consent (evidenced as provided in Article Seven) of
the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of each Series affected by such supplemental indenture (treated as one class), the Company, when authorized by a resolution of its Board
of Directors, and the Trustee for such Series of Securities may, from time to time and at any time, enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act of 1939 as in force at
the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of
the Securities of each such Series; provided, that the following modifications and amendments will not be effective against any Holder without its consent: no such supplemental indenture shall: (a) a change in the stated maturity date of
any payment of principal or interest; (b) a reduction in the principal amount of, or premium or interest on, any Security; (c) a change in place of payment where, or the currency in which, any payment on the Securities is payable;
(d) an impairment of a Holder’s right to sue the Company and its Subsidiaries for the enforcement of payments due on the Securities; or (e) a reduction in the percentage of outstanding Securities required to consent to a modification
or amendment of the Indenture or required to consent to a waiver of compliance with certain provisions of the Indenture or certain defaults under the Indenture. 
 Upon the request of the Company, accompanied by a copy of a resolution of its Board of Directors certified by the secretary or an assistant secretary of the Company authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee for such Series of Securities of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 7.1, the Trustee for such Series of Securities shall join
with the Company in the execution of such supplemental indenture 
  

 53 

 unless such supplemental indenture affects such Trustee’s own rights, duties or immunities under this Indenture or
otherwise, in which case such Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
 It
shall not be necessary for the consent of the Securityholders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Company shall
give notice in the manner and to the extent provided in Section 11.4 to the Holders of Securities of each Series affected thereby at their addresses as they shall appear on the Securities register of the Company, setting forth in general terms
the substance of such supplemental indenture. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. 
 For the purposes of this Section 8.2 only, if the Securities of any Series are issuable upon the exercise of warrants, each holder of an unexercised
and unexpired warrant with respect to such series shall be deemed to be a Holder of Outstanding Securities of such Series in the amount issuable upon the exercise of such warrant. For such purposes, the ownership of any such warrant shall be
determined by the Company in a manner consistent with customary commercial practices. The Trustee for such series shall be entitled to rely on an Officers’ Certificate as to the principal amount of Securities of such Series in respect of which
consents shall have been executed by holders of such warrants. 
 SECTION 8.3 Effect of Supplemental Indenture. Upon the execution of
any supplemental indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the Holders of Securities of each Series and Holders of Coupons affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 SECTION 8.4 Documents to Be Given to Trustee. The Trustee, subject to the provisions of Sections 6.1 and 6.2, shall receive an Officers’
Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article Eight complies with the applicable provisions of this Indenture. 
 SECTION 8.5 Notation on Securities in Respect of Supplemental Indentures. Securities of any Series (including any Coupons appertaining thereto)
authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article may bear, upon the direction of the Company, a notation in form satisfactory to the Trustee for the Securities of such Series as
to any matter provided for by such supplemental indenture or as to any action taken at any such meeting. If the Company or the Trustee shall so determine, new Securities of any Series and any Coupons appertaining thereto so modified as to conform,
in the 
  

 54 

 opinion of the Trustee and the Company’s Board of Directors, to any modification of this Indenture contained in any
such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Securities of such Series then Outstanding and any Coupons appertaining thereto then Outstanding. 
 ARTICLE NINE 
 CONSOLIDATION, MERGER, SALE OR
CONVEYANCE 
 SECTION 9.1 Company May Consolidate, etc., on Certain Terms. (a) Subject to the provisions of Section 9.2,
nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or merger of the Company with or into any other entity or entities (whether or not affiliated with the Company), or successive consolidations or mergers
in which the Company or its successor or successors shall be a party or parties, or shall prevent any sale, conveyance or lease of all or substantially all the property of the Company to any other entity (whether or not affiliated with the Company)
authorized to acquire and operate the same; provided, that in any such case: (i) either the Company shall be the surviving or continuing entity or the resulting or acquiring entity, if other than the Company, is organized and existing
under the laws of a United States jurisdiction and assumes all of the Company’s responsibilities and liabilities under the Indenture, including the payment of all amounts due on the Securities and performance of the covenants in the Indenture;
(ii) immediately after the transaction, and giving effect to the transaction, no Event of Default under the Indenture exists; (iii) if, as a result of such transaction, the Company’s properties or assets or any Restricted
Subsidiary’s properties or assets would become subject to a Lien not permitted pursuant to Section 3.6 without equally and ratably securing the Securities, steps shall have been taken to secure the Securities equally and ratably with all
indebtedness secured by such Lien; and (iv) the Company has delivered to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that the transaction and, if a supplemental indenture is required in connection with the
transaction, the supplemental indenture comply with the Indenture and that all conditions precedent to the transaction contained in the Indenture have been satisfied. 
 (b) If the Company consolidates or merges with or into any other entity or sells or leases all or substantially all of the Company’s
assets in compliance with the terms and conditions of this Indenture, the resulting or acquiring entity will be substituted for the Company in this Indenture and the Securities with the same effect as if such entity had been an original party to
this Indenture and the Securities. As a result, such successor entity may exercise the Company’s rights and powers under the Indenture and the Securities, in the Company’s name and, except in the case of a lease, the Company will be
released from all its liabilities and obligations under the Indenture and under the Securities. 
 (c) Notwithstanding the
foregoing provisions, the Company may transfer all of its property and assets to another entity if, immediately after giving effect to the transfer, such corporation is a Wholly-Owned Restricted Subsidiary.

 SECTION 9.2. Securities to be Secured in Certain Events. If, upon any consolidation, merger, sale,
conveyance or lease referred to in Section 9.1, or upon any consolidation or merger of any Subsidiary, or upon any sale, conveyance or lease of all or substantially all the property of any Subsidiary to any other Person, any Principal Property
or any shares of capital stock of any Restricted Subsidiary which is owned immediately after such consolidation, merger, sale, conveyance or lease by the Company or a Restricted Subsidiary or a successor to the Company pursuant to Sections 9.1 and
9.3 would thereupon become subject to any Lien (other than a Permitted Lien), the Company, if and to the extent it would be required to do so pursuant to Section 3.6, prior to or concurrently with such consolidation, merger, sale, conveyance or
lease, will effectively provide that the Securities shall be secured (equally and ratably with the indebtedness of or guaranteed by the Company or such Subsidiary secured by such Lien) by a Lien on such Principal Property or on the shares of capital
stock of such Restricted Subsidiary, for so long as such Principal Property or shares of capital stock shall be subject to such Lien. 
 SECTION 9.3 Successor Corporation Substituted. In case of any such consolidation, merger, sale or conveyance, and following such an assumption by the successor corporation, such successor corporation shall succeed to and be
substituted for the Company, with the same effect as if it had been named herein. Such successor corporation may cause to be signed, and may issue either in its own name or in the name of the Company prior to such succession any or all of the
Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities and Coupons, if any, appertaining thereto, which previously shall have been signed and delivered by the officers of the Company to the Trustee for
authentication, and any Securities which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Securities and Coupons, if any, appertaining thereto, so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities and Coupons, if any, appertaining thereto, theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities and Coupons, if
any, appertaining thereto, had been issued at the date of the execution hereof. 
 In case of any such consolidation, merger, sale, lease or
conveyance such changes in phraseology and form (but not in substance) may be made in the Securities and Coupons, if any, appertaining thereto, thereafter to be issued as may be appropriate. 
 In the event of any such sale or conveyance (other than a conveyance by way of lease) the Company or any successor corporation which shall theretofore
have become such in the manner described in this Article shall be discharged from all obligations and covenants under this Indenture and the Securities and may be liquidated and dissolved. 
 SECTION 9.4 Opinion of Counsel to Trustee. The Trustee, subject to the provisions of Sections 6.1 and 6.2, shall receive an Opinion of Counsel,
prepared in accordance with Section 11.5, as conclusive evidence that any such consolidation, merger, sale, lease or conveyance, and any such assumption, and any such liquidation or dissolution, complies with the applicable provisions of this
Indenture.

 SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS 
 SECTION 10.1 Satisfaction and Discharge of
Indenture. (A) If at any time (a) the Company shall have paid or caused to be paid the principal of and interest on all the Securities of any Series and Coupons, if any, appertaining thereto Outstanding hereunder (other than Securities
and Coupons which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.9) as and when the same shall have become due and payable, or (b) the Company shall have delivered to the Trustee for
cancellation all Securities of any Series and Coupons theretofore authenticated (other than any Securities of such Series and Coupons which have been destroyed, lost or stolen and which shall have been replaced or paid as provided in
Section 2.9) or (c)(i) all the Securities of such Series and Coupons not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be
called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and (ii) the Company shall have irrevocably deposited or caused to be deposited with the Trustee as trust funds the
entire amount in the currency required (other than moneys repaid by the Trustee or any Paying Agent to the Company in accordance with Section 10.4) and/or Government Obligations maturing as to principal and interest in such amounts and at such
times as will, in aggregate, ensure the availability of cash sufficient, in the opinion of a firm of independent certified public accountants, to pay at maturity or upon redemption all Securities of such Series and Coupons (other than any Securities
of such Series and Coupons which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.9) not theretofore delivered to the Trustee for cancellation, including principal and interest due or
to become due to such date of maturity as the case may be, and if, in any such case, the Company shall also pay or cause to be paid all other sums payable hereunder by the Company with respect to Securities of such Series and Coupons, then this
Indenture shall cease to be of further effect with respect to Securities of such Series and Coupons (except as to (i) rights of registration of transfer and exchange, and the Company’s right of optional redemption, (ii) substitution
of mutilated, defaced, destroyed, lost or stolen Securities and Coupons, (iii) rights of Holders to receive payments of principal thereof and interest thereon upon the original stated due dates therefore (but not upon acceleration) and
remaining rights of the Holders to receive mandatory sinking fund payments, if any, (iv) the rights, obligations and immunities of the Trustee hereunder and (v) the rights of the Securityholders of such Series as beneficiaries hereof with
respect to the property so deposited with the Trustee payable to all or any of them), and, subject to Section 10.5, the Trustee, on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and
expense of the Company, shall execute proper instruments acknowledging such satisfaction of and discharging this Indenture with respect to such Series; provided, that the rights of Holders of the Securities and Holders of Coupons to receive amounts
in respect of principal of and interest on the Securities and Coupons held by them shall not be delayed longer than required by then-applicable mandatory rules or policies of any securities exchange upon which the Securities are listed. The Company
agrees to reimburse the Trustee for any 
  

 57 

 costs or expenses thereafter reasonably and properly incurred and to compensate the Trustee for any services thereafter
reasonably and properly rendered by the Trustee in connection with this Indenture, the Securities of such Series and Coupons. 
 (B) In
addition to the provisions of Section 10.1(A), the Company may terminate its obligations under the Securities of any Series and this Indenture with respect to such Series, except those obligations referred to in the penultimate paragraph of
this Section 10.1, if the Company has irrevocably deposited or caused to be deposited with the Trustee at its Corporate Trust Office or such other office as the Trustee may designate, under the terms of an irrevocable trust agreement in form
and substance satisfactory to the Trustee, as trust funds in trust solely for the benefit of the Securityholders of such Series for that purpose, (i) cash in the currency required and/or, (ii) Government Obligations maturing as to
principal and interest in such amounts and at such times as are sufficient, in the opinion of a firm of independent certified public accountants, without consideration of any reinvestment of such principal or interest, to pay the principal of and
interest on the outstanding Securities of such Series and Coupons to maturity or redemption, as the case may be, provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such Government Obligations to
the payment of said principal of and interest on the Outstanding Securities and Coupons of such Series. 
 Such irrevocable trust agreement
shall include, among other things, provision for (1) payment of the principal of and interest on the Securities of such Series and Coupons when due (by redemption, sinking fund payments or otherwise), (2) the payment of the expenses of the
Trustee incurred or to be incurred in connection with carrying out such trust provisions, (3) rights of registration, transfer, substitution and exchange of Securities of such Series and Coupons in accordance with the terms stated in this
Indenture and (4) continuation of the rights and obligations and immunities of the Trustee as against the Securityholders of such Series as stated in this Indenture. 
 Notwithstanding the first paragraph of this Section 10.1(B), the Company’s obligations in Sections 2.8, 2.9, 3.1, 3.2, 3.8, 5.1, 6.6, 6.10, 10.4 and 10.5 shall survive until the Securities of such Series and
Coupons, if any, are no longer Outstanding; provided, however, that the Company’s obligations in Section 5.1 shall survive only with respect to Events of Default as defined in Sections 5.1(a), 5.1(b) and, to the extent relating to
continuing obligations of the Company, 5.1(c). Thereafter, the Company’s obligations in Sections 6.6, 10.4 and 10.5 shall survive. 
 After any such irrevocable deposit, accompanied by an Officers’ Certificate which shall state that the provisions of the first two paragraphs of this Section 10.1(B) have been complied with, and upon delivery by the Company to the
Trustee of (i) an Opinion of Counsel to the effect that either (a) as a result of such deposit and the related exercise of the Company’s option under this Section 10.1(B) registration will not be required under the Investment
Company Act of 1940, as amended, by the Company, the trust funds representing such deposit or the Trustee or (b) all necessary registrations under such Act have been effected, (ii) an Opinion of Counsel that such deposit and the related
exercise of the Company’s option under this Section 10.1(B) would not cause any 
  

 58 

 outstanding Security of such Series then listed on any nationally recognized or foreign securities exchange to be
delisted as a result thereof, and (iii) an Opinion of Counsel to the effect that Securityholders of such Series will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and discharge and will be
subject to Federal income tax on the same amount and in the same manner and at the same time as would have been the case if such deposit and discharge had not occurred, then the Company shall be discharged of its obligations under the Securities of
such Series and this Indenture with respect to such Series except for those surviving obligations specified above, and the Trustee upon request shall acknowledge in writing such discharge. Prior to the delivery of such acknowledgment, the Trustee
may require the Company to deliver to it an Officers’ Certificate and Opinion of Counsel, each stating that all conditions precedent provided for herein relating to the deposit and discharge contemplated by this provision have been complied
with, and the Trustee may also require that the Opinion of Counsel referred to in clause (i) of this paragraph shall also state that such deposit does not violate applicable law. 
 SECTION 10.2 Application by Trustee of Funds Deposited for Payment of Securities. Subject to Section 10.4, all moneys deposited with the
Trustee pursuant to Section 10.1 shall be held in trust and applied by it to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent), to the Holders of the particular Securities of such
Series and any Coupons appertaining thereto for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest; but such money need not be segregated from
other funds except to the extent required by law. 
 SECTION 10.3 Repayment of Moneys Held by Paying Agent. In connection with the
satisfaction and discharge of this Indenture with respect to Securities of any Series or Coupons, all moneys then held by any Paying Agent under the provisions of this Indenture with respect to such Series of Securities or Coupons shall, upon demand
of the Company, be repaid to it or paid to the Trustee and thereupon such Paying Agent shall be released from all further liability with respect to such moneys. 
 SECTION 10.4 Return of Unclaimed Moneys Held by Trustee and Paying Agent. Any moneys deposited with or paid to the Trustee or any Paying Agent for the payment of the principal of or interest on any Security of
any Series or Coupons and not applied but remaining unclaimed for two years after the date upon which such principal or interest shall have become due and payable, shall, upon the written request of the Company and unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Company by the Trustee for such Series or such Paying Agent, and the Holder of the Security of such Series or Holders of Coupons appertaining thereto
shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property laws, thereafter look only to the Company for any payment which such Holder may be entitled to collect, and all liability of the
Trustee or any Paying Agent with respect to such moneys shall thereupon cease. 
  

 59 

 SECTION 10.5 Reinstatement of Company’s Obligations. If the Trustee is unable to apply any
funds or Government Obligations in accordance with Section 10.1 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application or
by reason of the Trustee’s inability to convert any such funds or Government Obligations into the currency required to be paid with respect to the Securities of such Series, the Company’s obligations under this Indenture and the Securities
of any Series for which such application is prohibited shall be revived and reinstated as if no deposit had occurred pursuant to Section 10.1 until such time as the Trustee is permitted to apply all such funds or Government Obligations in
accordance with Section 10.1 or is able to convert all such funds or Government Obligations; provided, however, that if the Company has made any payment of interest on or principal of any of such Securities or Coupons because of the
reinstatement of its obligations, the Company shall be subrogated to the rights of the Securityholders of such Securities to receive such payment from the funds or Government Obligations held by the Trustee.

 MISCELLANEOUS PROVISIONS

 SECTION 11.1 Incorporators, Stockholders, Officers and Directors of Company Exempt from Individual Liability. No recourse under or
upon any obligation, covenant or agreement contained in this Indenture, in any Security or Coupon appertaining thereto, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such or against any past, present or
future stockholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by
any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities and Coupons, if any, by the Holders thereof and as part of the consideration for the issue of the Securities.

 SECTION 11.2 Provisions of Indenture for the Sole Benefit of Parties and Securityholders. Nothing in this Indenture or in the
Securities or Coupons, expressed or implied, shall give or be construed to give to any Person, firm or corporation, other than the parties hereto, any Paying Agent and their successors hereunder and the Holders of the Securities and Coupons, if any,
any legal or equitable right, remedy or claim under this Indenture or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the parties hereto and their successors and of the Holders of the
Securities and Coupons. 
 SECTION 11.3 Successors and Assigns of Company Bound by Indenture. All the covenants, stipulations,
promises and agreements in this Indenture contained by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not. 
 SECTION 11.4 Notices and Demands on Company, Trustee and Securityholders. Any notice or demand which by any provision of this Indenture is required or permitted to be given or served by the Trustee, by the

or made, for all purposes, if given or made at the Corporate Trust Office.

event, (1) if any of the Securities affected by such event are Registered Securities, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed by first-class mail, postage prepaid to such
Registered Holders as their names and addresses appear in the Security register within the time prescribed and (2) if any of the Securities affected by such event are Unregistered Securities or Coupon Securities, such notice shall 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 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, and any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given. 
 In case, by reason of the suspension of or irregularities in regular mail service, it shall be impracticable to mail notice to the Company and
Securityholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

Company to the Trustee to take any action under any of the provisions of this Indenture, the Company shall furnish to the Trustee an Officers’ Certificate stating that all conditions precedent provided for in this Indenture relating to the

person, such condition or covenant has been complied with.

statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters,
information with respect to which is in the possession of the Company, upon the certificate, statement or opinion of or representations by an officer or officers of the Company, unless such counsel knows that the certificate, statement or opinion or
representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous.

accounting matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous.

 SECTION 11.6 Payments Due on Saturdays, Sundays and Holidays. If the date of maturity of interest on or principal of the Securities
of any Series or Coupons appertaining thereto or the date fixed for redemption or repayment of any such Security or Coupon shall not be a Business Day, then payment of interest, premium, if any, or principal need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if made on the date of maturity or the date fixed for redemption, and no interest shall accrue for the period after such date. 
 SECTION 11.7 Conflict of Any Provision of Indenture with Trust Indenture Act of 1939. If and to the extent that any provision of this Indenture

direction, notice, consent or waiver hereunder, whether a quorum is present at a meeting of Holders of Securities or whether sufficient funds are available for redemption or for any other purpose, the principal amount of an Original Issue Discount

Section 5.1 and the principal amount of any Securities denominated in a Foreign Currency that shall be deemed to be outstanding for such purposes shall be determined by converting the Foreign Currency into Dollars at the Market Exchange Rate as
of the date of such determination.

 ARTICLE TWELVE 
 REDEMPTION OF
SECURITIES 
 SECTION 12.1 Notice of Redemption; Partial Redemptions. Notice of redemption to the Holders of Securities of any Series
to be redeemed as a whole or in part at the option of the Company shall be given by giving notice of such redemption as provided in Section 11.4, at least 30 days and not more than 60 days prior to the date fixed for redemption to such Holders
of Securities of such Series. Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a Series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption
of any other Security of such Series. 
 The notice of redemption to each such Holder shall identify the Securities to be redeemed (including
“CUSIP” or “ISIN” numbers), specify the date fixed for redemption, the redemption price, the Place or Places of Payment, that payment will be made upon presentation and surrender of such Securities, and that, unless otherwise
specified in such notice, Coupon Securities, if any, surrendered for payment must be accompanied by all Coupons maturing subsequent to the redemption date, failing which the amount of any such missing Coupon or Coupons will be deducted from the sum
due for payment, that such redemption is pursuant to the 
  

 63 

 mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption
will be paid as specified in such notice and that on and after said date interest thereon or on the portions thereof to be redeemed will cease to accrue and that, if less than all of the Outstanding Securities of a Series are to be redeemed, the
identification and principal amount of the Securities to be redeemed. If less than all of the Securities of any Series and to be redeemed, the notice of redemption shall specify the numbers of the Securities of such Series to be redeemed, and, if
only Unregistered Securities of any Series are to be redeemed, and if such Unregistered Securities may be exchanged for Registered Securities, the last date on which exchanges of Unregistered Securities for Registered Securities not subject to
redemption may be made. In case any Security of a Series is to be redeemed in part, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon
surrender of such Security and any Coupons appertaining thereto, a new Security or Securities of such Series in principal amount equal to the unredeemed portion thereof with appropriate Coupons will be issued. 
 The notice of redemption of Securities of any Series to be redeemed at the option 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. The Company shall give the Trustee at least 45 days prior written notice of any redemption hereunder. 
 Not later than 9:00 a.m., New York time, on the redemption date specified in the notice of redemption given as provided in this Section, the Company will
have on deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 3.4) an amount of money in the currency in which the
Securities of such Series and any Coupons appertaining thereto are payable (except as otherwise specified pursuant to Section 2.3 and except as provided in Sections 2.12(b), (e) and (f) of this Indenture) sufficient to redeem on the
redemption date all the Securities of such Series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If less than all the Outstanding Securities of a Series are to be
redeemed, the Company will deliver to the Trustee at least 60 days prior to the date fixed for redemption an Officers’ Certificate stating the aggregate principal amount of Securities to be redeemed. 
 If less than all the Securities of a Series are to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate and fair,
Securities of such Series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such Series or any multiple thereof. The Trustee shall promptly notify the
Company in writing of the Securities of such Series selected for redemption and, in the case of any Securities of such Series selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless
the context otherwise requires, all provisions relating to the redemption of Securities of any Series shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which
has been or is to be redeemed. 
  

 64 

 SECTION 12.2 Payment of Securities Called for Redemption. If notice of redemption has been given
as above provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed
for redemption, and on and after said date (unless the Company shall default in the payment of such Securities at the redemption price, together with interest accrued to said date) interest on the Securities or portions of Securities so called for
redemption shall cease to accrue and, except as provided in Sections 6.5 and 10.4, such Securities shall cease from and after the date fixed for redemption to be entitled to any benefit or security under this Indenture, and the Holders thereof shall
have no right in respect of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender of such Securities at a place of payment specified in said
notice, said Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided that any semiannual payment of
interest on Registered Securities becoming due on the date fixed for redemption shall be payable to the Holders of such Securities registered as such on the relevant record date subject to the terms and provisions of Section 2.4 hereof.

 If any Coupon Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing on or after the date fixed
for redemption, such Security may be paid after deducting from the redemption price an amount equal to the face amount of all such missing Coupons or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee, if
there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any missing Coupon in respect of which a
deduction shall have been made from the redemption price, such Holder shall be entitled to receive the amount so deducted; provided, however, that, unless otherwise provided pursuant to Section 2.3, interest represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an office or agency located outside of the United States. 
 If any Security
called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest borne by the Security. 
 Upon presentation of any Security redeemed in part only and the Coupons appertaining thereto, the Company shall execute and the Trustee shall
authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities and the Coupons appertaining thereto, of authorized denominations, in principal amount equal to the unredeemed portion of
the Security so presented. 
 SECTION 12.3 Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities
shall be excluded from eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by an authorized officer of the Company and delivered to the Trustee at least 40 days prior
to the last date on which notice of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by, either (a) the Company or (b) an 
  

 65 

 entity specifically identified in such written statement directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company.

 SECTION 13.3. Call of Meetings by Company or Holders. In case at any time the Company, pursuant to
a resolution of its Board of Directors, or the Holders of at least 10% in aggregate principal amount of the Outstanding Securities of any or all Series, as the case may be, shall have requested the Trustee for such Series to call a meeting of
Holders of Securities of any or all Series, as the case may be, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee for such Series shall not have given the notice of such meeting
within 20 days after receipt of such request, then the Company or such Holders may determine the time and the place in Chicago, Illinois, or such other Place of Payment for such meeting and may call such meeting to take any action authorized in
Section 13.1, by giving notice thereof as provided in Section 13.2. 
 SECTION 13.4. Qualifications for Voting. To be
entitled to vote at any meeting of Holders, a person shall be (a) a Holder of one or more Securities with respect to which such meeting is being held or (b) a person appointed by an instrument in writing as proxy by such Holder. The only
persons who shall be entitled to be present or to speak at any meeting of Holders shall be the persons entitled to vote at such meeting and their counsel and any representatives of the Trustee for the Securities of the Series with respect to which
such meeting is being held and its counsel and any representatives of the Company and its counsel. 
 SECTION 13.5. Regulations.
Notwithstanding any other provisions of this Indenture, the Trustee for the Securities of any Series may make such reasonable regulations as it may deem advisable for any meeting of Holders of the Securities of such Series, in regard to proof of the
holding of Securities of such Series and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such
other matters concerning the conduct of the meeting as it shall think fit. 
 The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of the Securities of such Series as provided in Section 13.3, in which case the Company or the Holders calling the meeting, as the case
may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by majority vote of the meeting. 
 Subject to Section 7.4, at any meeting each Holder of Securities with respect to which such meeting is being held or proxy therefore shall be entitled to one vote for each $1,000 (or the equivalent in the
currency in which such Securities are denominated, as determined pursuant to Section 11.11) principal amount (in the case of the Original Issue Discount Securities, such principal amount to be determined as provided in Section 11.11) of
Securities held or represented by him. However, no vote shall be cast or counted at any meeting in respect of any such Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting
shall have no right to vote other than by virtue of the Securities of such Series held by him or instruments in writing aforesaid duly designating him as the person to vote on behalf of other Holders of such Series. At any meeting of Holders, the
presence of persons holding or representing Securities with respect to which such meeting is being held in 
  

 67 

 an aggregate principal amount sufficient to take action on the business for the transaction of which such meeting was
called shall constitute a quorum, but, if less than a quorum is present, the persons holding or representing a majority in aggregate principal amount of such Securities represented at the meeting may adjourn such meeting with the same effect, for
all intents and purposes, as though a quorum had been present. Any meeting of Holders of Securities with respect to which a meeting was duly called pursuant to the provisions of Section 13.2 or Section 13.3 may be adjourned from time to
time by a majority of such Holders present, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice. 
 SECTION 13.6. Voting. The vote upon any resolution submitted to any meeting of Holders of Securities with respect to which such meeting is being held shall be by written ballots on which shall be subscribed the
signatures of such Holders or of their representatives by proxy and the serial number or numbers of the Securities held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes
cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of
Holders shall be prepared by the secretary of the meeting and there shall be attached to such record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that such notice was given in the manner and to the extent provided in Section 11.4. The record shall show the serial numbers of the Securities voting in favor of or against
any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee.

 Any record so signed and verified shall be conclusive evidence of the matters therein stated. 
 SECTION 13.7. No Delay of Rights by Meeting. Nothing in this Article Thirteen shall be deemed or construed to authorize or permit, by reason of
any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the
provisions of this Indenture or of the Securities of any Series.
