 Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 SECTION 104. Acts of Holders; Record Dates. 
 Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such
Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section.

 The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a
witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where
such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or
the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 

The ownership of Securities shall be proved by the Security Register. 

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such Security. 
 The Company may set any day as a record
date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, 

  
 -8-

 
demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series,
provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after
such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration
Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
 The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default,
(ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to
Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date,
the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 

With respect to any record date set pursuant to this Section, the party hereto that sets such record dates may designate any day as the
“Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto
in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to
this Section, the party hereto that set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date 

  
 -9-

 
with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after
the applicable record date. 
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with
regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such
principal amount. 
 SECTION 105. Notices, Etc., to Trustee and Company. 

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with, 
 (1) the Trustee by any Holder or by the
Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee and received at its Corporate Trust Office, or 

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at UBS AG, Structured Derivative Products, 677 Washington Blvd, Stamford, CT 06901, Attn: Mark Ritter, with a copy to Legal and External
Affairs, 677 Washington Blvd., Stamford, CT, 06901, Attn: Equities Group, or at any other address previously furnished in writing to the Trustee by the Company. 
 SECTION 106. Notice to Holders; Waiver. 
 Where this Indenture provides for
notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

  
 -10-

 Where this Indenture provides for Notice of any event to a Holder of a Global Security, such
notice shall be sufficiently given if given to the Depositary for such Security (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the
giving of such notice. 
 SECTION 107. Conflict with Trust Indenture Act. 

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be
a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be. 
 SECTION 108. Effect of Headings and Table of Contents.

 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the
construction hereof. 
 SECTION 109. Successors and Assigns. 
 All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. 
 SECTION 110. Separability Clause. 
 In case any provision in this Indenture
or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 111. Benefits of Indenture. 
 Nothing in this Indenture or in the
Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. 

SECTION 112. Governing Law. 
 This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York. 
 SECTION 113. Submission to Jurisdiction; Appointment of Agent for Service of Process. 
 The Company hereby appoints the Company, acting through its branch office at 1285 Avenue of the Americas, New York, New York 10019 (or such other address in the Borough of Manhattan, The City of New York,
as such agent shall furnish in writing to the Trustee) as its 

  
 -11-

 
authorized agent (the “Authorized Agent”) upon which process may be served in any legal action or proceeding against it with respect to its obligations under this Indenture or the
Securities of any series, as the case may be, instituted in any federal or state court in the Borough of Manhattan, The City of New York by the Holder of any Security, and agrees that service of process upon the Authorized Agent, together with
written notice of said service mailed or delivered to the Company, addressed as provided in Section 105, shall be deemed in every respect effective service of process upon the Company in any such legal action or proceeding, and the Company
hereby irrevocably submits to the non-exclusive jurisdiction of any such court in respect of any such legal action or proceeding and waives, to the extent it may effectively do so, any objection it may have to the laying of the venue of any such
legal action or proceeding. Such appointment shall be irrevocable so long as the Holders of Securities shall have any rights pursuant to the terms of the Securities or of this Indenture until the appointment of a successor Authorized Agent by the
Company and such successor’s acceptance of such appointment. The Company reserves the right to appoint another person located, or with an office, in the Borough of Manhattan, The City of New York, selected in its sole discretion, as a successor
Authorized Agent, and upon acceptance of such appointment by such a successor the appointment of the prior Authorized Agent shall terminate. If for any reason the Company ceases to be able to act as the Authorized Agent or to have an address in the
Borough of Manhattan, The City of New York, the Company will appoint a successor Authorized Agent in accordance with the preceding sentence. The Company further agrees to take any and all action, including the filing of any and all documents and
instruments as may be necessary to continue such designation and appointment of such agent or successor in full force and effect for as long as required hereunder. 
 SECTION 114. Legal Holidays. 
 In any case where any Interest Payment
Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically
states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity.

shall bear interest at the rate of     % per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment. Interest on
any overdue principal or premium shall be payable on demand.

address shall appear in the Security Register and, provided, further, that if this Security is a Global Security, payment may be made pursuant to the Applicable Procedures of the Depositary as permitted in said Indenture.

            , redeem any Securities of this series as contemplated by [if applicable, insert—Clause (2) of] the preceding paragraph as a

part, at the election of the Company as provided in the Indenture at [their principal amount] [if the Security is an Original Issue Discount Security, insert formula for determining the amount], together in the case of any such
redemption with any accrued but unpaid interest to the Redemption Date.] 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities 

  
 -17-

 
of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a
receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in
principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the
Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days
after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the
Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is
registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this
series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities of this series are issuable only in registered form without coupons in denominations of $         and any integral multiple thereof. As provided in
the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested

as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 SECTION 303. Execution, Authentication,
Delivery and Dating. 
 The Securities shall be executed on behalf of the Company by any two Authorized Officers. The
signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual or facsimile
signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after the execution
and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities under this Indenture 

  
 -22-

 
in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, 

(1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by
Section 201, that such form has been established in conformity with the provisions of this Indenture; 
 (2)
if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 

(3) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and
subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s
own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the
Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such
documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. 
 Each Security shall be dated the date of its authentication. 
 No Security shall
be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 
 SECTION 304.
Temporary Securities. 
 Pending the preparation of definitive Securities of any series, the Company may execute, and
upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive
Securities in lieu of which they are 

  
 -23-

 
issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such
Securities. 
 If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to
be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 
 SECTION
305. Registration, Registration of Transfer and Exchange. 
 The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities
and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of like tenor and aggregate principal amount. 
 At the option of the Holder,
Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 

  
 -24-

 No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304,
906 or 1107 not involving any transfer. 
 If the Securities of any series (or of any series and specified tenor) are to be
redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (B) to register the transfer
of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 The provisions of Clauses (1), (2), (3) (4) and (5) below shall apply only to Global Securities: 
 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 
 (2) Notwithstanding any other provision in this Indenture, and subject to such applicable provisions, if any, as may be specified as contemplated by Section 301, no Global Security may be exchanged
in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such
Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, (B) there shall have occurred and
be continuing an Event of Default with respect to such Global Security or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301.

 (3) Subject to Clause (2) above and to such applicable provisions, if any, as may be specified as
contemplated by Section 301, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the
Depositary for such Global Security shall direct. 
 (4) Every Security authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and
shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
 (5) Except for the exchange rights provided in Clause (2) above, owners of beneficial interest in a Global Security held on their behalf by a Depositary shall not be entitled to receive physical
delivery of Securities in definitive form, shall not be considered the Holders 

  
 -25-

 
thereof for any purpose under this Indenture and shall have no rights under this Indenture with respect to such Global Security, and such Depositary may be treated by the Company, the Trustee and
any agent of any of them as the Holder and owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, the Depositary for any Global Security may grant proxies and otherwise authorize any person, including the
beneficial owners of interest in such Global Security, to take any action which a Holder is entitled to take under this Indenture with respect to such Global Security. 
 SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. 
 If any
mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding. 
 If there shall be delivered to the Company and the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like
tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed,
lost or stolen Security has become or is about to become due and payable, the Company in its absolute discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series
issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities. 
 SECTION 307. Payment of Interest; Interest Rights Preserved. 

Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which
is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date
for such interest.

 Any interest on any Security of any series which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such
series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in
writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, 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 which shall be not more than 15 days and not less than 10 days prior to the date of
the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 

(2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not
inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to
this Clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing provisions of this
Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other
Security. 
 In the case of any Security which is converted after any Regular Record Date and on or prior to the next succeeding
Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion,
and such 

  
 -27-

 
interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of
business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is converted, interest whose Stated Maturity is after the date of conversion of such Security shall
not be payable. Notwithstanding the foregoing, the terms of any Security that may be converted may provide that the provisions of this paragraph do not apply, or apply with such additions, changes or omissions as may be provided thereby, to such
Security. 
 SECTION 308. Persons Deemed Owners. 
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 SECTION 309.
Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit
against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in
this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. 
 SECTION 310. Computation of Interest. 
 Except as otherwise specified as
contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 

SECTION 311. CUSIP Numbers 
 The Company in issuing the Securities may use CUSIP numbers (if then generally in use) and, if so, the Trustee shall use CUSIP numbers 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. Any such redemption shall not be affected by any defect in or omission of such numbers.

any premium and interest for whose payment such money has been deposited with the Trustee. 
 ARTICLE FIVE

 SECTION 501. Events of Default. 
 “Event of Default”, wherever
used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 
 (1) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or 

(2) default in the payment of the principal of or any premium on any Security of that series at its Maturity; or

 (3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that
series; or 
 (4) default in the performance, or breach, of any covenant or warranty of the Company in this
Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of series of Securities
other than that series), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 10% in

decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Swiss bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order appointing a custodian, receiver,

any such other decree or order unstayed and in effect for a period of 60 consecutive days; or 
 (6) the
commencement by the Company of a voluntary case or proceeding under any applicable Swiss bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it

by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the taking of corporate
action by the Company in furtherance of any such action; or 
 (7) any other Event of Default provided with
respect to Securities of that series. 
 SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default (other than an Event of Default specified in Section 501(5) or 501(6)) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities
of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing
to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default specified in Section 501(5) or 501 (6) with
respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if 

  
 -31-

 (1) the Company has paid or deposited with the Trustee a sum sufficient to
pay 
 (A) all overdue interest on all Securities of that series, 

(B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such
declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
 (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and 

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel; 
 and 

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of
Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if 
 (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,

 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 

  
 -32-

 SECTION 504. Trustee May File Proofs of Claim. 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to participate as a member, voting or otherwise, of any official committee appointed on such matter, to collect and receive any moneys or other property payable or deliverable on any such claims and to
distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607. 
 No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other
similar committee. 
 SECTION 505. Trustee May Enforce Claims Without Possession of Securities. 

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been
recovered. 
 SECTION 506. Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of
principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee under Section 607; and 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities
in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively.

  
 -33-

 SECTION 507. Limitation on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of
Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute
any such proceeding; and 
 (5) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood
and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to
seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert. 

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date),
and, if the terms of such Security so provide, to convert such Security in accordance with its terms, and to institute suit for the enforcement of any such payment and, if applicable, any such right to convert, and such rights shall not be impaired
without the consent of such Holder. 
 SECTION 509. Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has
been discontinued or abandoned for any reason, or 

  
 -34-

 
has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be
restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 

SECTION 510. Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred
upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

 SECTION 511. Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of
any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be. 
 SECTION 512. Control by Holders. 

The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that 

(1) such direction shall not be in conflict with any rule of law or with this Indenture, and 

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

 SECTION 513. Waiver of Past Defaults. 
 The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder
with respect to such series and its consequences, except a default 

  
 -35-

 (1) in the payment of the principal of or any premium or interest on any
Security of such series, or 
 (2) in respect of a covenant or provision hereof which under Article Nine cannot
be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such
waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right
consequent thereon. 
 SECTION 514. Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any
party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section
nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. 
 SECTION 515. Waiver of Usury, Stay or Extension Laws. 
 The Company
covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 

ARTICLE SIX 

THE TRUSTEE 
 SECTION 601. Certain Duties and Responsibilities. 
 The duties and
responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably
assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

  
 -36-

 SECTION 602. Notice of Defaults. 

If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such
series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(4) with respect to Securities of such series, no such
notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of
Default with respect to Securities of such series. 
 SECTION 603. Certain Rights of Trustee. 

Subject to the provisions of Section 601: 
 (1) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order,
bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 

(2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or
Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution; 
 (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee
(unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 
 (4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered
or omitted by it hereunder in good faith and in reliance thereon; 
 (5) the Trustee shall be under no obligation
to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the
costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or
attorney; 

  
 -37-

 (7) 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 and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 

(8) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be
authorized or within the discretion or rights or powers conferred upon it by this Indenture; and 
 (9) except
during the continuance of an Event of Default, the Trustee need perform only those duties as are specifically set forth in this Indenture. 
 The Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or
powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
 In the event that an Event of Default has occurred and is continuing, the Trustee shall, in the exercise of its power, use the degree of care of a prudent person in similar circumstances in the conduct of
his or her own affairs. 
 SECTION 604. Not Responsible for Recitals or Issuance of Securities. 

The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof. 

SECTION 605. May Hold Securities. 
 The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 

SECTION 606. Money Held in Trust. 
 Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it
hereunder except as otherwise agreed with the Company. 

  
 -38-

 SECTION 607. Compensation and Reimbursement. 

The Company agrees 
 (1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation
of a trustee of an express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 
 (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance
or administration of the trust or trusts hereunder, including the costs and expenses of enforcing this Indenture against the Company (including Section 607) and defending itself against any claim, whether asserted by any Holder or the Company,
or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 To secure the
Company’s payment obligations in this Section 607, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the principal amount, premium, if any, or
interest, if any, as the case may be, on particular Securities. 
 The Company’s payment obligations pursuant to this
Section 607 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 501(5) or (6), the expenses are intended to constitute expenses of administration under any
applicable law. 
 SECTION 608. Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series. 
 SECTION 609. Corporate Trustee Required; Eligibility. 

There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee
hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least $50,000,000 and has its Corporate Trust Office
in the Borough of Manhattan, The City of New York. If any such Person publishes reports 

  
 -39-

 
of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust
Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 SECTION 610. Resignation and Removal; Appointment of Successor. 
 No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of
Section 611. 
 The Trustee may resign at any time with respect to the Securities of one or more series by giving written
notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the
Trustee and to the Company. 
 If at any time: 

(1) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder
who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall cease to be
eligible under Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case,
(A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or 

  
 -40-

 
Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such
series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the
Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Company shall give
notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the
manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
 SECTION 611. Acceptance of Appointment by Successor. 
 In case of the
appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 
 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to
the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to
transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates,
(2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to
provide 

  
 -41-

 
for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such
supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 

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

SECTION 612. Merger, Conversion, Consolidation or Succession to Business. 

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

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 

SECTION 614. Appointment of Authenticating Agent. 
 The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be 

  
 -42-

 
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of
such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of
this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in
Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers
and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607. 
 If an
appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication
in the following form:

 This is one of the Securities of the series designated therein referred to in the
within-mentioned Indenture.

 ARTICLE TEN 
 COVENANTS 
 SECTION 1001. Payment of Principal, Premium and

 SECTION 1002. Maintenance of Office or Agency. 
 The Company will maintain

where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office

any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

SECTION 1003. Money for Securities Payments to Be Held in Trust.

disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company
shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such
sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written
request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee
all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with respect to such money. 
 Any money deposited with
the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease. 

SECTION 1004. Statement by Officers as to Default. 
 The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best
knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if
the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 SECTION
1005. Existence. 
 Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that
the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.

 SECTION 1006. Payment of Taxes and Other Claims. 

The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes,
assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by appropriate proceedings. 
 SECTION 1007. Payment of Additional
Amounts. 
 Payments under the Securities will be made without deduction or withholding for or on account of any present or
future tax, duty, assessment or governmental charge imposed upon or as a result of such payments by Switzerland or any jurisdiction in which a branch of the Company through which any Security is issued is located (or any political subdivision or
taxing authority thereof or therein) (a “Relevant Jurisdiction”) (“Taxes”), unless required by law. To the extent any such Taxes are so levied or imposed, the Company will, subject to the exceptions and limitations set forth
below, pay such additional amounts (“Additional Amounts”) to the Holder of any Security who is not a resident of the Relevant Jurisdiction as may be necessary in order that every net payment of the principal of and interest on such
Security and any other amounts payable on such Security, after withholding for or on account of such Taxes imposed upon or as a result of such payment, will not be less than the amount provided for in such Security to be then due and payable.
However, the Company will not be required to make any payment of Additional Amounts to any such Holder if such payment can be made without such deduction or withholding by a paying agent other than the one required to make such a deduction or
withholding. Further, the Company will not be required to make any payment of Additional Amounts to any such Holder for or on account of: 
 (i) any such Taxes which would not have been so imposed but for (a) the existence of any present or former connection between such Holder (or between a fiduciary, settler, beneficiary, member or
shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation) and the Relevant Jurisdiction including, without limitation, such Holder (or such fiduciary, settler, beneficiary, member or shareholder) being or
having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein or (b) the presentation by or on behalf of the Holder of any such
Security payment on a date more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; 

(ii) any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, duty, assessment or
governmental charge; 

  
 -52-

 (iii) any Taxes which are payable otherwise than by withholding or deduction
from payments on or in respect of any Security; 
 (iv) any Taxes which would not have been imposed but for the
failure of a Holder, or any intermediary, custodian or broker, to comply with certification, information or other reporting requirements concerning the nationality, residence or identity of the holder or beneficial owner of such Security, if such
compliance is required by statute or by regulation of or on behalf of the Relevant Jurisdiction as a precondition to relief or exemption from such tax, assessment or other governmental charge; 

(v) any Taxes imposed solely because the Holder is a bank purchasing the Security in the ordinary course of its lending
business; 
 (vi) any Taxes imposed on (A) a Holder that actually or constructively owns 10% or more of the
combined voting power of all classes of stock of the Company entitled to vote; or (B) contingent interest as described in section 871(h)(4) of the Code; or 
 (vii) any combination of items (i) through (vi) above; 
 nor shall Additional Amounts be
paid with respect to any payment on a Security to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required to be included in the income, for tax purposes, of a
beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of the
Security. 
 In addition, no Additional Amounts will be required to be paid on account of any deduction or withholding imposed
or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation,
rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code. 
 The provisions of this Section 1007 shall also apply to any Taxes imposed by any jurisdiction in which a Person into which the Company has merged or to which the Company has conveyed, transferred or
leased its property is a resident for tax purposes, and such jurisdiction shall thereafter be treated in the same manner as a Relevant Jurisdiction for purposes of this Section 1007. 

For purposes of this Section 1007, any references to principal of and/or interest on Securities shall be deemed to include a
reference to any relevant premium and/or Additional Amounts payable in respect of such Securities. 

  
 -53-

 SECTION 1008. Waiver of Certain Covenants. 

Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the
Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such series or in
Article Eight if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 

ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 
 SECTION
1101. Applicability of Article. 
 Securities of any series which are redeemable before their Stated Maturity shall be
redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article. 
 SECTION 1102. Election to Redeem; Notice to Trustee. 
 The election of the
Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the
Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least 5 Business Days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 

SECTION 1103. Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single
Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the
Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of 

  
 -54-

 
any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the
minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 

If any Security selected for partial redemption is converted at the Holder’s option in part before termination of the conversion
right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted at the Holder’s option
during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 
 The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal
amount thereof to be redeemed. 
 The provisions of the two preceding paragraphs shall not apply with respect to any redemption
affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for such Security. 
 For all purposes of this Indenture, unless the
context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is
to be redeemed. 
 SECTION 1104. Notice of Redemption. 
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 5 Business Days nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be
redeemed, at his address appearing in the Security Register. 
 All notices of redemption shall state: 

(1) the Redemption Date, 
 (2) the Redemption Price, 
 (3) if less than all the Outstanding
Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less
than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, 

  
 -55-

 (4) that on the Redemption Date the Redemption Price will become due and
payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 
 (5) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 
 (6) for any Securities that by their terms may be converted at the Holder’s option, the terms of conversion, the date on which the right to convert the Security to be redeemed will terminate and the
place or places where such Securities may be surrendered for conversion, 
 (7) the CUSIP number or numbers, if
any, with respect to such Securities, and 
 (8) that the redemption is for a sinking fund, if such is the case.

 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the
Company’s request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. 
 SECTION 1105. Deposit of
Redemption Price. 
 Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date, other than any Securities called for redemption on that date which have been converted at the Holder’s option prior to the date of such deposit. 

If any Security called for redemption is converted, any money deposited with the Trustee or with any Paying Agent or so segregated and
held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last paragraph of Section 307 or in the terms of such Security) be
paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such trust. 
 SECTION 1106. Securities
Payable on Redemption Date. 
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease
to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. 

  
 -56-

 If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 SECTION 1107. Securities Redeemed in Part. 
 Any Security which is to be
redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and
of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. 

SECTION 1108. Optional Redemption for Tax Reasons. 
 Unless otherwise specified for a particular series of Securities, the Company may, on giving not more than 60 nor less than 10 days’ notice to the Trustee (which notice shall be irrevocable),
redeem the Securities of any Series then outstanding at a redemption price equal to the principal amount of the Securities (or if the Securities are original issue discount securities, such amount as determined pursuant to the formula set forth in
the applicable indenture supplement) plus any related Additional Amounts (as defined in Section 1007 herein), in each case with respect to the Securities being redeemed, in the event that: (a) the Company determines that, as a result of
any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of a Relevant Jurisdiction (as defined in Section 1007) affecting taxation, or any change in official position regarding the application or
interpretation of such laws, regulations or rulings, the Company has or will become obligated to pay Additional Amounts with respect to the Securities of such Series; or (b) a person who is a resident for tax purposes in a jurisdiction other
than a Relevant Jurisdiction into which the Company is merged or to which it has conveyed, transferred or leased its property is required to pay Additional Amounts. Nothing in subsection (b) of this Section 1108 requires the Company to use
reasonable measures to avoid the obligation of pay Additional Amounts in the event of such merger, conveyance, transfer or lease. The Trustee will notify the Holders at least 20 days prior to the date fixed for any such redemption. Prior to the
giving of any notice of redemption for tax reasons as described in this paragraph, the Company shall deliver to the Trustee (i) an Officers’ Certificate stating that the Company is entitled to effect such redemption and setting forth a
statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred and (ii) an opinion of counsel to such effect based on such statement of facts; provided that no such notice of redemption
shall be given earlier than 60 days prior to the earliest date on which the Company would be obligated to pay such Additional Amounts if a payment in respect of the Securities were then due.

 ARTICLE TWELVE 
 SINKING FUNDS 
 SECTION 1201. Applicability of
Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any
series except as otherwise specified as contemplated by Section 301 for such Securities. 
 The minimum amount of any
sinking fund payment provided for by the terms of any Securities is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred
to as an “optional sinking fund payment”. If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied
to the redemption of Securities as provided for by the terms of such Securities. 
 SECTION 1202. Satisfaction of Sinking Fund Payments with
Securities. 
 The Company (1) may deliver Outstanding Securities of a series (other than any previously called
for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments
pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent
provided for by the terms of such Securities; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the
Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 

SECTION 1203. Redemption of Securities for Sinking Fund. 
 Not less than 60 days prior to each sinking fund payment date for any Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking
fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities
pursuant to Section 1202, and will also deliver to the Trustee any Securities to be so delivered. Not less than 45 days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

 ARTICLE THIRTEEN 

DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 1301. Company’s Option to Effect Defeasance or Covenant Defeasance. 

The Company may elect, at its option at any time, to have Section 1302 or Section 1303 applied to any Securities or any series
of Securities, as the case may be, designated pursuant to Section 301 as being defeasible pursuant to such Section 1302 or 1303, in accordance with any applicable requirements provided pursuant to Section 301 and upon compliance with
the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. 

SECTION 1302. Defeasance and Discharge. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged
from its obligations with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means
that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned
(and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, (2) the
Company’s obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance with
this Article, the Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the prior exercise of its option (if any) to have Section 1303 applied to such Securities. 

SECTION 1303. Covenant Defeasance. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company shall be released from its
obligations under Section 801(3), Section 1006 and any covenants provided pursuant to Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such Securities, and (2) the occurrence of any event specified in
Sections 501(4) (with respect to any of Section 801(3), Section 1006 and any such covenants provided pursuant to Section 301(18), 901(2) or 901(7)), and 501(7) shall be deemed not to be or result in an Event of Default, in each
case with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means
that, with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of
Section 501(4)), whether 

  
 -59-

 
directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document,
but the remainder of this Indenture and such Securities shall be unaffected thereby. 
 SECTION 1304. Conditions to Defeasance or Covenant
Defeasance. 
 The following shall be the conditions to the application of Section 1302 or Section 1303 to any
Securities or any series of Securities, as the case may be: 
 (1) The Company shall irrevocably have deposited
or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 609 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of
principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and
discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means
(x) any security which is (i) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not
callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is
specified in Clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held,
provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation
or the specific payment of principal or interest evidenced by such depositary receipt. 
 (2) In the event of an
election to have Section 1302 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been
published by, the U.S. Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable U.S. Federal income tax law, in either case (A) or (B) to the effect that, and based thereon
such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for U.S. Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be
subject to U.S. Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 

  
 -60-

 (3) In the event of an election to have Section 1303 apply to any
Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for U.S. Federal income tax purposes
as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to U.S. Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and
Covenant Defeasance were not to occur. 
 (4) The Company shall have delivered to the Trustee an Officers’
Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 

(5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such
Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 501(5) and (6), at any time on or prior to the 90th day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until after such 90th day). 
 (6) Such
Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 

(7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under,
any other agreement or instrument to which the Company is a party or by which it is bound. 
 (8) Such Defeasance
or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration
thereunder. 
 (9) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 

SECTION 1305. Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. 

Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 1304
in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions 

  
 -61-

 
of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the
Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law. 

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities. 

Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. 

SECTION 1306. Reinstatement. 
 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 1302 or 1303 shall be revived
and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1305 with respect to
such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be
subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. 
  

 
 This instrument
may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

 SECTION 102. Compliance Certificates and Opinions. 

Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall
furnish to the Trustee such certificates and opinions as may be required under the Trust Indenture Act; provided, however, that no such opinion shall be required in connection with the issuance of Securities of any Series. Each such certificate or
opinion shall be given in the form of an Officers’ Certificate, if to be given by an officer of the Company, or an Opinion of Counsel, if to be given by counsel, and shall comply with the requirements of the Trust Indenture Act and any other
requirements set forth in this Indenture. 
 Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (except for certificates provided for in Section 1004) shall include, 
 (1) a

 SECTION 103. Form of

 In any case where several matters are required to be certified by, or covered by an opinion

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

  
 -8-

 
certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company,
unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be
consolidated and form one instrument. 
 SECTION 104. Acts of Holders; Record Dates. 

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby)
are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other
manner which the Trustee deems sufficient. 
 The ownership of Securities shall be proved by the Security Register. 

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such Security. 
 The Company may set any day as a record
date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or 

  
 -9-

 
take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such
series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after
such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Final Date by Holders of the requisite number of Outstanding Warrants of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no
action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite number of Outstanding Warrants of the relevant series on the date such action is
taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Final Date to be given to the Trustee in writing and
to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
 The Trustee may set any day
as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any request to institute proceedings referred to in
Section 506(2) or (iii) any direction referred to in Section 511, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on
such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Final Date by Holders of the requisite number of Outstanding Warrants of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite number of Outstanding Warrants of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at
the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Final Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in
Section 106. 
 With respect to any record date set pursuant to this Section, the party hereto that sets such record dates
may designate any day as the “Final Date” and from time to time may change the Final Date to any earlier or later day; provided that no such 

  
 -10-

 
change shall be effective unless notice of the proposed new Final Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set
forth in Section 106, on or prior to the existing Final Date. If a Final Date is not designated with respect to any record date set pursuant to this Section, the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Final Date with respect thereto, subject to its right to change the Final Date as provided in this paragraph. Notwithstanding the foregoing, no Final Date shall be later than the 180th day after
the applicable record date. 
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with
regard to any particular Warrants may do so with regard to all or any lesser number of such Warrants or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any lesser number of such
Warrants. 
 SECTION 105. Notices, Etc., to Trustee and Company. 

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with, 
 (1) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee and received at its Corporate Trust Office, or 
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the
Company addressed to it at UBS AG, Structured Derivative Products, 677 Washington Blvd., Stamford, CT, 06901, Attn: Mark Ritter, with a copy to Legal and External Affairs, 677 Washington Blvd., Stamford, CT, 06901, Attn: Equities Group or at any
other address previously furnished in writing to the Trustee by the Company. 
 SECTION 106. Notice to Holders; Waiver.

 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise
herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver
shall be the equivalent of such 

  
 -11-

 
notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give
such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 Where this Indenture provides for Notice of any event to a Holder of a Global Security, such notice shall be sufficiently given if given to the Depositary for such Security (or its designee), pursuant to
its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. 
 SECTION 107. Conflict with Trust Indenture Act. 
 If any provision hereof limits,
qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. 

SECTION 108. Effect of Headings and Table of Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 

SECTION 109. Successors and Assigns. 
 All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. 
 SECTION 110. Separability Clause. 
 In case any provision in this Indenture or in
the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

SECTION 111. Benefits of Indenture. 
 Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or
equitable right, remedy or claim under this Indenture. 

  
 -12-

 SECTION 112. Characterization of Warrants. 

By executing this Indenture, the Company intends that the characterization, for accounting and other purposes, of the Universal Warrants
as indebtedness or debt for borrowed money, or as any other type of obligation which is not indebtedness or debt for borrowed money, shall not be affected solely by the fact that the Universal Warrants have been issued under an indenture, as opposed
to any other instrument, or solely as a result of any of the terms and definitions used hereunder with respect to Universal Warrants. 
 SECTION 113. Governing Law. 
 This Indenture and the Securities shall be governed
by and construed in accordance with the law of the State of New York. 
 SECTION 114. Submission to Jurisdiction; Appointment of
Agent for Service of Process. 
 The Company hereby appoints the Company, acting through its branch office at 1285 Avenue of the
Americas, New York, New York 10019 (or such other address in the Borough of Manhattan, The City of New York, as such agent shall furnish in writing to the Trustee) as its authorized agent (the “Authorized Agent”) upon which process may be
served in any legal action or proceeding against it with respect to its obligations under this Indenture or the Securities of any series, as the case may be, instituted in any federal or state court in the Borough of Manhattan, The City of New York
by the Holder of any Security, and agrees that service of process upon the Authorized Agent, together with written notice of said service mailed or delivered to the Company, addressed as provided in Section 105, shall be deemed in every respect
effective service of process upon the Company in any such legal action or proceeding, and the Company hereby irrevocably submits to the non-exclusive jurisdiction of any such court in respect of any such legal action or proceeding and waives, to the
extent it may effectively do so, any objection it may have to the laying of the venue of any such legal action or proceeding. Such appointment shall be irrevocable so long as the Holders of Securities shall have any rights pursuant to the terms of
the Securities or of this Indenture until the appointment of a successor Authorized Agent by the Company and such successor’s acceptance of such appointment. The Company reserves the right to appoint another person located, or with an office,
in the Borough of Manhattan, The City of New York, selected in its sole discretion, as a successor Authorized Agent, and upon acceptance of such appointment by such a successor the appointment of the prior Authorized Agent shall terminate. If for
any reason the Company ceases to be able to act as the Authorized Agent or to have an address in the Borough of Manhattan, The City of New York, the Company will appoint a successor Authorized Agent in accordance with the preceding sentence. The
Company further agrees to take any and all action, including the filing of any and all documents and instruments as may be necessary to continue such designation and appointment of such agent or successor in full force and effect for as long as
required hereunder.

 SECTION 115. Legal Holidays. 

In any case where the Payment or Settlement Date or Redemption Date of any Security, or any date on which a Holder of any Security has
the right to exercise such Security, shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment or delivery of any money or Warrant Property payable or deliverable with respect to such Security, or exercise of such Security, need not be made at such Place of Payment on such date, but may
be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Payment or Settlement Date or Redemption Date, or on such date for exercise, as the case may be.

future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay or deliver the money or Warrant Property due with respect to this Security at the time and place herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration

(11) the date on which the right to exercise the Securities of the series shall commence and the Expiration Date of the series or, if the
Securities of the series are not continuously exercisable throughout such period, the specific date or dates on which they will be exercisable; 
 (12) if applicable, that any Securities of the series shall be issuable in whole or in part in the form of one or more Global Securities and, in such case, the respective Depositaries for such Global
Securities, the form of any legend or legends which shall be borne by any such Global Security in addition to or in lieu of that set forth in Section 206, and any circumstances in addition to or in lieu of those set forth in Clause (2) of
the last paragraph of Section 305 in which any such Global Security may be exchanged in whole or in part for Securities registered, and any transfer of such Global Security in whole or in part may be registered, in the name or names of Persons
other than the Depositary for such Global Security or a nominee thereof and any other provisions governing exchanges or transfers of any such Global Security; 
 (13) any warrant agents, Depositaries, Paying Agents, transfer agents or registrars or any determination agents, Calculation Agents or other agents with respect to Securities of the series; 

(14) whether the Securities of the series will be issued separately or together as a unit (a “Unit”) with one or more other
securities of the Company or any other person and, if the Securities of the series are to be issued as components of Units, whether and on what terms the Securities of the series may be separated from the other components of such Units prior to the
Expiration Date of such Securities; 

  
 -35-

 (15) if other than denominations of 100 Warrants and any multiple thereof, the denominations
in which any Securities of the series shall be issuable; 
 (16) the Place of Payment with respect to Securities of the series,
if other than the Corporate Trust Office; 
 (17) any addition to or change in the covenants set forth in Article Ten which
applies to Securities of the series; 
 (18) any provisions necessary to permit or facilitate the issuance, payment or exercise
of any Securities of the series that may be exercised for securities or other property other than Securities of the same series and of like tenor, whether in addition to, or in lieu of, any payment of money or delivery of other property and whether
at the option of the Company or otherwise; 
 (19) any addition to, elimination of or other change in the Events of Default which
applies to Securities of the series, including making Events of Default inapplicable or changing the remedies available to Holders of the Securities of the series upon an Event of Default; and 

(20) if applicable, that Additional Amounts, pursuant to Section 1007, will not be payable by the Company in respect of the
Securities of the series; and 
 (21) any other terms of the series (which terms shall not be inconsistent with the provisions of
this Indenture, except as permitted by Section 901(5)). 
 All Securities of any one series shall be substantially
identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’ Certificate
referred to above or in any such indenture supplemental hereto. 
 If any of the terms of the series are established by action
taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’
Certificate setting forth the terms of the series. 

  
 -36-

 The Securities are unsecured contractual obligations of the Company and rank pari passu with
the Company’s other unsecured contractual obligations and with the Company’s unsecured and unsubordinated debt. 
 No
Security shall entitle the Holder or any beneficial owner thereof to any of the rights of a holder or beneficial owner of Warrant Property, including the right to receive the payment of any dividends on, principal of, or premium or interest on
Warrant Property or to vote or to enforce any rights under any documents governing Warrant Property. 
 SECTION 302.
Denominations. 
 The Securities of each series shall be issuable only in registered form without coupons and only in such
denominations as shall be specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of 100 Warrants
and any multiple thereof. 
 SECTION 303. Execution, Authentication, Delivery and Dating. 

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

 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201,
that such form has been established in conformity with the provisions of this Indenture; 

  
 -37-

 (2) if the terms of such Securities have been established by or pursuant to Board Resolution
as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 

(3) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 If
such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the
Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Notwithstanding the
provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to
Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication
upon original issuance of the first Security of such series to be issued. 
 Each Security shall be dated the date of its
authentication. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose
unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture. 
 SECTION 304. Temporary Securities. 

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the

  
 -38-

 
definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine,
as evidenced by their execution of such Securities. 
 If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series
upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any
series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate number of Warrants. Until so
exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 

SECTION 305. Registration, Registration of Transfer and Exchange. 

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in
any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 

Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for
that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and
aggregate number of Warrants. 
 At the option of the Holder, Securities of any series may be exchanged for other Securities of
the same series, of any authorized denominations and of like tenor and aggregate number of Warrants, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same contractual obligation, and entitled to the same
benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 

  
 -39-

 Every Security presented or surrendered for registration of transfer or for exchange shall
(if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly
authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or
1107 not involving any transfer. 
 If the Securities of any series are to be redeemed in part, the Company shall not be
required (A) to issue, register the transfer of or exchange any Securities of that series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for
redemption under Section 1103 and ending at the close of business on the day of such mailing (or during such period as otherwise specified as contemplated by Section 301 for such Securities), or (B) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 The provisions of Clauses (1), (2), (3), (4) and (5) below shall apply only to Global Securities: 
 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 
 (2) Notwithstanding any other provision in this Indenture, and subject to such applicable provisions, if any, as may be specified as contemplated by Section 301, no Global Security may be exchanged
in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such
Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, (B) there shall have occurred and
be continuing an Event of Default with respect to such Global Security or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301.

  
 -40-

 (3) Subject to Clause (2) above and to such applicable provisions, if any, as may be
specified as contemplated by Section 301, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such
names as the Depositary for such Global Security shall direct. 
 (4) Every Security authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and
shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
 (5) Except for the exchange rights provided in Clause (2) above, owners of beneficial interest in a Global Security held on their behalf by a Depositary shall not be entitled to receive physical
delivery of Securities in definitive form, shall not be considered the Holders thereof for any purpose under this Indenture and shall have no rights under this Indenture with respect to such Global Security, and such Depositary may be treated by the
Company, the Trustee and any agent of any of them as the Holder and owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, the Depositary for any Global Security may grant proxies and otherwise authorize any
person, including the beneficial owners of interest in such Global Security, to take any action which a Holder is entitled to take under this Indenture with respect to such Global Security. 

In the event that upon any exercise of Warrants evidenced by a certificate the number of Warrants exercised shall be less than the total
number of Warrants evidenced by such certificate, there shall be issued to the Holder thereof or his assignee a new certificate evidencing the number of Warrants of the same series and of like tenor not exercised, provided that in the case of
Warrants evidenced by one or more Global Securities, in lieu of issuing such new certificate the Trustee shall note the cancellation of such exercised Warrants and the number of such Warrants not exercised and remaining Outstanding by notation on
such Global Security(ies). 
 SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. 

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same series and of like tenor and number of Warrants and bearing a number not contemporaneously outstanding. 

  
 -41-

 If there shall be delivered to the Company and the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like
tenor and number of Warrants and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed,
lost or stolen Security has become exercisable, or is about to be exercised, or deemed to be exercised, the Company in its absolute discretion may, instead of issuing a new Security, direct the Trustee to treat the same as if it had received the
Security together with an irrevocable exercise notice in proper form in respect thereof, as established with respect to the Securities of such series. 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series
issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to
the replacement, payment or settlement of mutilated, destroyed, lost or stolen Securities. 
 SECTION 307. Persons Deemed
Owners. 
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment or delivery of any money or Warrant Property payable or deliverable with respect to such
Security and for all other purposes whatsoever, whether or not such payment or delivery with respect to such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the
contrary. 
 SECTION 308. Cancellation. 
 All Securities surrendered for exercise, redemption or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be

  
 -42-

 
delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and
sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this
Indenture. All canceled Securities held by the Trustee shall be disposed of as directed by a Company Order. 
 SECTION 309.
CUSIP Numbers. 
 The Company in issuing the Securities may use CUSIP numbers (if then generally in use) and, if so, the Trustee
shall use CUSIP numbers 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. Any such redemption shall not be affected by any defect in or omission of such numbers. 

SECTION 310. Calculation Agent. 
 Pursuant to Section 301, the Company may, in connection with any series of Securities, appoint UBS Securities LLC or any other person or entity as Calculation Agent to make any calculations as may be
required pursuant to the terms of such series of Securities. Any such Calculation Agent shall act as an independent expert, and the Company may provide that the Calculation Agent’s calculations and determinations under this Indenture shall,
absent manifest error, be final and binding on the Company, the Trustee and the Holders of the Securities of such series. 

ARTICLE FOUR 
 SATISFACTION AND DISCHARGE 
 SECTION 401. Satisfaction and Discharge
of Indenture. 
 This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of
exercise, registration of transfer or exchange of Securities herein expressly provided for, and the Trustee, at the expense of the Company, shall execute without recourse, representation or warranty of any kind, proper instruments acknowledging
satisfaction and discharge of this Indenture, when 

  
 -43-

 (1) either 
 (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced, paid or settled as provided in
Section 306 and (ii) Securities for whose payment or settlement money or Warrant Property has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid or redelivered to the Company or
discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 
 (B) all
such Securities not theretofore delivered to the Trustee for cancellation 
 (i) have been exercised, 

(ii) will be automatically exercised at their Expiration Date within one year, or 

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds or trust property in trust for the
purpose money or Warrant Property in an amount sufficient to pay and discharge the entire contractual obligation on such Securities not theretofore delivered to the Trustee for cancellation, for all amounts of money or Warrant Property due with
respect to such Securities to the date of such deposit or to the Payment or Settlement Date or Redemption Date of such Securities, as the case may be; 
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture have been complied with. 
 Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money or Warrant Property shall have been deposited with the Trustee pursuant to subclause
(B) of Clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive. 

  
 -44-

 SECTION 402. Application of Trust Money and Warrant Property. 

Subject to the provisions of the last paragraph of Section 1003, all money and Warrant Property deposited with the Trustee pursuant
to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment or delivery, either directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of all amounts of money or Warrant Property due with respect to such Securities for whose payment or settlement such money or Warrant Property has been deposited with the
Trustee. 
 ARTICLE FIVE 
 REMEDIES 
 SECTION 501. Events of Default. 

Except as otherwise specified as contemplated by Section 301 for Securities of any series, “Event of Default”, wherever
used herein with respect to any Security of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 
 (1)
default in the payment or delivery of any money or Warrant Property in respect of such Security (but not such a default in respect of any other Security of that or any other series) in accordance with its terms; 

(2) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty
a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of series of Securities other than that series), and continuance of
such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 10% in number of the Outstanding Warrants of that
series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; 
 (3) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Swiss bankruptcy,
insolvency, reorganization or other similar law or (B) a decree or order appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property,

  
 -45-

 
or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60
consecutive days; 
 (4) the commencement by the Company of a voluntary case or proceeding under any applicable Swiss bankruptcy,
insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Swiss bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking
reorganization or relief under any applicable Swiss law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar
official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing or its inability to pay its debts generally as they become due, or the taking of
corporate action by the Company in furtherance of any such action; or 
 (5) any other Event of Default provided with respect to
such Security or to Securities of that series. 
 Notwithstanding any other provision of this Indenture or of any Security, a
failure by the Company to perform any obligation or otherwise observe any covenant in any Security or in this Indenture insofar as it applies to any Security shall not constitute a default unless all conditions precedent to the Company’s
obligation to be satisfied by the Holder of such Security shall have been satisfied. 
 SECTION 502. Collection of Amounts Due
and Suits for Enforcement by Trustee. 
 The Company covenants that if default is made in the payment or delivery of any money
or Warrant Property in respect of any Security in accordance with its terms upon satisfaction by the Holder thereof of all conditions precedent to the Company’s obligation to make such payment or delivery to be satisfied by such Holder, the
Company will, upon demand of the Trustee, pay to it, for the benefit of the Holder of such Security, the whole amount of Warrant Property or money then due and payable on such Security and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If an Event of Default with respect to any Security occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holder of such Security by
such appropriate judicial proceedings as the 

  
 -46-

 
Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy. 
 SECTION 503. Trustee May File Proofs of Claim. 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to participate as a member, voting or otherwise, of any official committee appointed on such matter, to collect and receive any moneys, Warrant Property or other property payable or deliverable on any such
claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 607. 
 No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar
committee. 
 SECTION 504. Trustee May Enforce Claims Without Possession of Securities. 

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been
recovered. 
 SECTION 505. Application of Money Collected. 

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of amounts due with respect to the Securities, 

  
 -47-

 
upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee under Section 607; 

SECOND: To the payment of the amounts then due and unpaid on the Securities in respect of which or for the benefit of which such money
has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities; and 
 THIRD: To the Company. 
 SECTION 506. Limitation on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such Holder has
previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 

(2) the Holders of not less than 25% in number of the Outstanding Securities of that series shall have made written request to the Trustee
to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders
have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in number of the Outstanding Securities of that series; 
 it being understood and intended that no one or more of such Holders shall
have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 

  
 -48-

 SECTION 507. Unconditional Right of Holders to Receive Money or Warrant Property Due With
Respect to Securities and to Exercise. 
 Notwithstanding any other provision in this Indenture, the Holder of any Security
shall have the right, which is absolute and unconditional, to receive payment or delivery of the money or Warrant Property due with respect to such Security on the Payment or Settlement Date (or, in the case of redemption, on the Redemption Date) of
such Security and to exercise such Security in accordance with its terms, and to institute suit for the enforcement of any such payment or delivery and such right to exercise, and such rights shall not be impaired without the consent of such Holder.

 SECTION 508. Restoration of Rights and Remedies. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 509. Rights and Remedies Cumulative. 
 Except as otherwise provided with
respect to the replacement, payment or settlement of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 510. Delay or Omission Not Waiver. 
 No delay or omission of the Trustee
or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given
by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

SECTION 511. Control by Holders. 
 The Holders of a majority in number of the Outstanding Warrants of any series shall have the right to direct the time, method and place of conducting any

  
 -49-

 
proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that 

(1) such direction shall not be in conflict with any rule of law or with this Indenture, and 

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

SECTION 512. Waiver of Past Defaults. 
 The Holders of not less than a majority in number of the Outstanding Warrants of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect
to such series and its consequences, except a default 
 (1) in the payment or delivery of the money or Warrant Property due on
any Security of such series or in respect of any Holder’s right to exercise any Security, or 
 (2) in respect of a covenant
or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend
to any subsequent or other default or impair any right consequent thereon. 
 SECTION 513. Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the
Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. 

SECTION 514. Waiver of Usury, Stay or Extension Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay
or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this 

  
 -50-

 
Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 ARTICLE SIX 
 THE TRUSTEE 

SECTION 601. Certain Duties and Responsibilities. 
 The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section. 
 SECTION 602. Notice of Defaults. 

If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series
notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(2) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series. 
 SECTION 603. Certain Rights of Trustee. 

Subject to the provisions of Section 601: 
 (1) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order,
warrant or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently
evidenced by a Board Resolution; 

  
 -51-

 (3) whenever in the administration of this Indenture the Trustee shall deem it desirable
that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’
Certificate; 
 (4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
 (5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless
such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, warrant or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the
Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; 

(7) 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 and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 
 (8) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this
Indenture; and 
 (9) except during the continuance of an Event of Default, the Trustee need perform only these duties as are
specifically set forth in this Indenture. 
 The Trustee shall not be required to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. 

  
 -52-

 In the event that an Event of Default has occurred and is continuing, the Trustee shall, in
the exercise of its power, use the degree of care of a prudent person in similar circumstances in the conduct of his or her own affairs. 
 SECTION 604. Not Responsible for Recitals or Issuance of Securities. 
 The
recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities
or the proceeds thereof. 
 SECTION 605. May Hold Securities. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or
any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent. 
 SECTION 606. Money or Warrant Property Held in Trust. 

Money or Warrant Property held by the Trustee in trust hereunder need not be segregated from other funds, securities or other property
except to the extent required by law. The Trustee shall be under no liability for interest on any money or Warrant Property received by it hereunder except as otherwise agreed in writing with the Company. 

SECTION 607. Compensation and Reimbursement. 
 The Company agrees 
 (1) to pay to the Trustee from time to time reasonable
compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as
may be attributable to its negligence or bad faith; and 

  
 -53-

 (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or
expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of enforcing this Indenture against the Company
(including Section 607) and defending itself against any claim, whether asserted by any Holder or the Company, or liability in connection with the exercise or performance of any of its powers or duties hereunder. 

To secure the Company’s payment obligations in this Section 607, the Trustee shall have a lien prior to the Securities on all
money or property held or collected by the Trustee, except that held in trust to pay the principal amount, premium, if any, or interest, if any, as the case may be, on particular Securities. 

The Company’s payment obligations pursuant to this Section 607 shall survive the discharge of this Indenture. 

When the Trustee incurs expenses after the occurrence of a Default specified in Section 501(3) or (4), the expenses are intended to
constitute expenses of administration under any applicable Swiss, Federal or State bankruptcy, insolvency or other similar law. 

SECTION 608. Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series. 
 SECTION 609. Corporate Trustee Required; Eligibility. 

There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee
hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least $50,000,000 and has its Corporate Trust Office
in the Borough of Manhattan, The City of New York. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and
to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee
with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

  
 -54-

 SECTION 610. Resignation and Removal; Appointment of Successor. 

No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until
the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611. 

The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company.
If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Trustee may be
removed at any time with respect to the Securities of any series by Act of the Holders of a majority in number of the Outstanding Warrants of such series, delivered to the Trustee and to the Company. 

If at any time: 

(1) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder who has been a
bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall cease to be eligible under Section 609
and shall fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) the Trustee shall become
incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 
 then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with
respect to all Securities, or (B) subject to Section 513, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the

  
 -55-

 
Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a
majority in number of the Outstanding Warrants of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable
requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office. 
 SECTION 611. Acceptance of Appointment by Successor.

 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its
charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all money, Warrant Property and other
property held by such retiring Trustee hereunder. 
 In case of the appointment hereunder of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor
Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or 

  
 -56-

 
those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be
deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in
the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee
relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all money, Warrant Property and other property held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 
 Upon request of
any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph,
as the case may be. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor
Trustee shall be qualified and eligible under this Article. 
 SECTION 612. Merger, Conversion, Consolidation or Succession to
Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities. 

  
 -57-

 SECTION 613. Preferential Collection of Claims Against Company. 

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

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or 

  
 -58-

 
upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve.
Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 The Trustee agrees to pay to
each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607. 

If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
 This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

(i) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of the Holder of any such Security with respect to such
provision or (B) shall become effective only when there is no such Security Outstanding; or 
 (6) to secure the Securities;
or 
 (7) to establish the form or terms of Securities of any series as permitted by Sections 201 and 301; or 

  
 -63-

 (8) to evidence and provide for the acceptance of appointment hereunder by a successor
Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee,
pursuant to the requirements of Section 611; or 
 (9) to add to or change any of the provisions of this Indenture with
respect to any Securities that by their terms may be exercised for securities or other property other than Securities of the same series and of like tenor, in order to permit or facilitate the issuance, payment, settlement or exercise of such
Securities; or 
 (10) to cure any ambiguity, to correct or supplement any provision herein which may be defective or
inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Indenture, provided that such action pursuant to this Clause (10) shall not adversely affect the interests of
the Holders of Securities of any series in any material respect. 
 SECTION 902. Supplemental Indentures With Consent of
Holders. 
 With the consent of the Holders of more than 50% in number of the Outstanding Warrants of each series affected by
such supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such
supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby, 
 (1) change the
terms of any Security with respect to the Payment or Settlement Date or exercise price thereof, or reduce the amount of money or reduce the amount or change the kind of Warrant Property payable or deliverable upon the exercise thereof or any premium
payable upon the redemption thereof, or change any Place of Payment where, or the coin or currency in which, any Security or any money payable or deliverable upon the exercise thereof is payable, or permit the Company to redeem any Security if,
absent such supplemental indenture, the Company would not be permitted to do so, or impair the right to institute suit for the enforcement of any such payment or delivery on or after the Payment or Settlement Date (or, in the case of redemption, on
or after the Redemption Date) thereof, or impair the Holder’s right to exercise such Security on the terms provided therein, or 

  
 -64-

 (2) if any Security provides that the Holder may require the Company to repurchase such
Security, impair such Holder’s right to require repurchase of such Security on the terms provided therein, or 
 (3) reduce
the percentage in number of the Outstanding Warrants of any one or more series (considered separately or together as one class, as applicable), the consent of whose Holders is required for any such supplemental indenture, or the consent of whose
Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, or 

(4) modify any of the provisions of this Section, Section 512 or Section 1008, except to increase any such percentage or to
provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of
any Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section and Section 1008, or the deletion of this proviso, in accordance with the requirements of Sections 611 and 901(8).

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

  
 -65-

 SECTION 904. Effect of Supplemental Indentures. 

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 

SECTION 905. Conformity with Trust Indenture Act. 
 Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 
 ARTICLE TEN

 COVENANTS 
 SECTION 1001. Payment or Delivery of Money or Warrant Property. 
 The Company
covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay or deliver the money or Warrant Property payable or deliverable by the Company with respect to the Securities of that series in accordance with
the terms of the Securities and this Indenture. 
 SECTION 1002. Maintenance of Office or Agency. 

Subject to the last paragraph of this section, the Company will maintain in each Place of Payment for any series of Securities an office
or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities may be surrendered upon exercise and where notices
and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If
at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office
of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 

  
 -66-

 The Company may also from time to time designate one or more other offices or agencies where
the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company
of its obligation pursuant to the first sentence of the preceding paragraph to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such other office or agency. 
 With respect to any
Global Security, and except as otherwise may be specified for such Global Security as contemplated by Section 301, the Corporate Trust Office of the Trustee shall be the Place of Payment where such Global Security may be presented or
surrendered for exercise, payment or delivery of money or Warrant Property due with respect to such Security or registration of transfer or exchange, or where successor Securities may be delivered in exchange therefor, provided, however, that any
such payment, delivery, presentation or surrender effected pursuant to the Applicable Procedures of the Depositary for such Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with the
provisions of this Indenture. 
 SECTION 1003. Money and Warrant Property for Securities Payments and Deliveries to Be Held in
Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or
before the Payment or Settlement Date of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto money or Warrant Property sufficient to pay or deliver the money or Warrant Property becoming due on
such date until such sums or property shall be paid or delivered to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to the Payment or Settlement Date
of the Securities of that series, deposit with a Paying Agent money or Warrant Property sufficient to pay or deliver the money or Warrant Property becoming due with respect to such Securities on such date, such money or Warrant Property to be held
as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that 

  
 -67-

 
such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any
other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all money or Warrant Property held in trust by such
Paying Agent for payment in respect of the Securities of that series. 
 The Company may at any time, for the purpose of
obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay or deliver, or by Company Order direct any Paying Agent to pay or deliver, to the Trustee all money or Warrant Property held in trust by the Company or such
Paying Agent, such money or Warrant Property to be held by the Trustee upon the same trusts as those upon which such money or Warrant Property were held by the Company or such Paying Agent; and, upon such payment or delivery by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with respect to such money or Warrant Property. 

Any money or Warrant Property deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment or
delivery of the amounts due on any Security of any series in accordance with its terms and remaining unclaimed for two years after such amounts have become due and payable or deliverable shall be paid or delivered to the Company on Company Request,
or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment or delivery thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money or property, and all liability of the Company as trustee thereof, shall thereupon cease. 
 SECTION 1004. Statement by Officers as to Default. 
 The Company will deliver to
the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the
performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and
the nature and status thereof of which they may have knowledge. 
 SECTION 1005. Existence. 

Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. 

  
 -68-

 SECTION 1006. Payment of Taxes and Other Claims. 

The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes,
assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate proceedings. 
 SECTION 1007. Payment of Additional
Amounts. 
 Payments under the Securities will be made without deduction or withholding for or on account of any present or
future tax, duty, assessment or governmental charge imposed upon or as a result of such payments by Switzerland or any jurisdiction in which a branch of the Company through which any Security is issued is located (or any political subdivision or
taxing authority thereof or therein) (a “Relevant Jurisdiction”) (“Taxes”), unless required by law. To the extent any such Taxes are so levied or imposed, the Company will, subject to the exceptions and limitations set forth
below, pay such additional amounts (“Additional Amounts”) to the Holder of any Security who is not a resident of the Relevant Jurisdiction as may be necessary in order that every net payment of the principal of and interest on such
Security and any other amounts payable on such Security, after withholding for or on account of such Taxes imposed upon or as a result of such payment, will not be less than the amount provided for in such Security to be then due and payable.
However, the Company will not be required to make any payment of Additional Amounts to any such Holder if such payment can be made without such deduction or withholding by a paying agent other than the one required to make such a deduction or
withholding. Further, the Company will not be required to make any payment of Additional Amounts to any such Holder for or on account of: 
 (i) any such Taxes which would not have been so imposed but for (a) the existence of any present or former connection between such Holder (or between a fiduciary, settler, beneficiary, member or
shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation) and the Relevant Jurisdiction including, without limitation, such Holder (or such fiduciary, settler, beneficiary, member or shareholder) being or
having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein or (b) the presentation by or on behalf of the Holder of any such
Security payment on a date more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; 

  
 -69-

 (ii) any estate, inheritance, gift, sales, transfer or personal property tax or any similar
tax, duty, assessment or governmental charge; 
 (iii) any Taxes which are payable otherwise than by withholding or deduction
from payments on or in respect of any Security; 
 (iv) any Taxes which would not have been imposed but for the failure of a
Holder, or any intermediary, custodian or broker, to comply with certification, information or other reporting requirements concerning the nationality, residence or identity of the holder or beneficial owner of such Security, if such compliance is
required by statute or by regulation of or on behalf of the Relevant Jurisdiction as a precondition to relief or exemption from such tax, assessment or other governmental charge; 

(v) any Taxes imposed solely because the Holder is a bank purchasing the Security in the ordinary course of its lending business;

 (vi) any Taxes imposed on (A) a Holder that actually or constructively owns 10% or more of the combined voting power of
all classes of stock of the Company entitled to vote; or (B) contingent interest as described in section 871(h)(4) of the Code; or 
 (vii) any combination of items (i) through (vi) above; 
 nor shall Additional Amounts be
paid with respect to any payment on a Security to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required to be included in the income, for tax purposes, of a
beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of the
Security. 
 In addition, no Additional Amounts will be required to be paid on account of any deduction or withholding imposed
or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation,
rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code. 
 The provisions of this Section 1007 shall also apply to any Taxes imposed by any jurisdiction in which a Person into which the Company has merged or to which the Company has conveyed, transferred or
leased its property is a resident for tax purposes, and such jurisdiction shall thereafter be treated in the same manner as a Relevant Jurisdiction for purposes of this Section 1007. 

  
 -70-

 SECTION 1008. Waiver of Certain Covenants. 

Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the
Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 301(3), 901(2) or 901(7) for the benefit of the Holders of such series or in
Article Eight or Section 1008 if before the time for such compliance, the Holders of at least a majority in number of the Outstanding Warrants of such series shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 

SECTION 1101. Applicability of Article. 
 Securities of any series which are redeemable before their Expiration Date shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for
such Securities) in accordance with this Article. 
 SECTION 1102. Election to Redeem; Notice to Trustee. 

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

  
 -71-

 
from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate, provided that the unredeemed portion of any
Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence. 
 If any Security selected for partial redemption is exercised in
part before termination of the exercise right with respect to the portion of the Security so selected, the exercised portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been
exercised during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 
 The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the amount
thereof to be redeemed. 
 The provisions of the two preceding paragraphs shall not apply with respect to any redemption
affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security. 
 For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of such Securities which has been or is to be redeemed. 

SECTION 1104. Notice of Redemption. 
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 10 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his
address appearing in the Security Register. 
 All notices of redemption shall state: 

(1) the Redemption Date, 
 (2) the Redemption Price, 
 (3) if less than all the Outstanding Securities of any
series consisting of more than a single Security are to be redeemed, the identification (and, in 

  
 -72-

 
the case of partial redemption of any such Securities, the amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a
single Security are to be redeemed, the amount of the particular Security to be redeemed, 
 (4) that on the Redemption Date the
Redemption Price will become due and payable upon each such Security to be redeemed, 
 (5) the place or places where each such
Security is to be surrendered for payment of the Redemption Price, and 
 (6) if applicable, the terms of exercise, the date on
which the right to exercise the Security to be redeemed will terminate and the place or places where such Securities may be surrendered for exercise. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the
Company and shall be irrevocable. 
 SECTION 1105. Deposit of Redemption Price. 

Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of all the Securities which are to be redeemed on that date, other than any Securities called for redemption on
that date which have been exercised prior to the date of such deposit. 
 If any Security called for redemption is exercised,
any money deposited with the Trustee or with any Paying Agent or so segregated and held in trust for the redemption of such Security shall be paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such
trust. 
 SECTION 1106. Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price. 

SECTION 1107. Securities Redeemed in Part. 
 Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company 

  
 -73-

 
and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in number equal to and in exchange for the unredeemed portion of the Security so
surrendered. 
 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be
an original, but all such counterparts shall together constitute but one and the same instrument. 

  
 -74-
