a reasonable period of time. The Bank of New York Mellon is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with Section 4.02. 
 Prior to the Notes Fungibility Date, upon
surrender for registration of transfer of any Rule 144A Note or Regulation S Note, as the case may be, to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set
forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Rule 144A Notes or Regulation S Notes, as the case may be, of any
authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. Following the Notes Fungibility Date, upon surrender for registration of transfer of any Note to the Note
Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and not bearing the restrictive legends required by Section 2.05(c). 

  
 15 

 Prior to the Notes Fungibility Date, Rule 144A Notes and Regulation S Notes, as the case may
be, may be exchanged for other Rule 144A Notes or Regulation S Notes, as the case may be, of any authorized denominations and of a like aggregate principal amount, upon surrender of the Rule 144A Notes or Regulation S Notes, as the case may be, to
be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Rule 144A Notes or Regulation S Notes, as the case may be, are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Rule 144A Notes or Regulation S Notes, as the case may be, that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. Following the Notes
Fungibility Date, Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount but not bearing the restrictive legend required by Section 2.05(c), upon surrender of the Notes to be exchanged at
any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the
exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 
 All Notes presented or surrendered for
registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a
written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in
writing. 
 No service charge shall be imposed by the Company, the Transfer Agent, the Note Registrar, any
co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp, issue, transfer or
similar tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or
registration of transfer. The Company shall pay the ADS Depositary’s fees for issuance of the ADSs. 
 None of the Company, the
Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for
conversion, such portion thereof surrendered for conversion, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15 or (iii) any Notes selected for redemption in accordance
with Article 16. 

  
 16 

 All Notes issued upon any registration of transfer or exchange of Notes in accordance with
this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth
paragraph from the end of Section 2.05(c) all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and
exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary in accordance with this Indenture (including the restrictions on transfer set forth herein) and the
procedures of the Depositary therefor. Prior to the Notes Fungibility Date, the Rule 144A Notes shall be represented by one or more Global Notes and the Regulation S Notes shall be represented by one or more separate Global Notes. Following the
Notes Fungibility Date, the Rule 144A Notes and the Regulation S Notes may be represented by one or more of the same Global Notes. 
 (c)
Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any ADSs (including the Ordinary Shares represented thereby) delivered upon conversion of the Notes that
are required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including the legend set forth
below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such
restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 

Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the
last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any
certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than ADSs (including the Ordinary Shares represented thereby) issued upon conversion thereof, which shall bear the legend set forth in
Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that
continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 under the Securities Act or any similar provision then in force under the Securities Act, or unless otherwise agreed by the
Company in writing, with notice thereof to the Trustee): 
 THIS SECURITY, THE AMERICAN DEPOSITARY SHARES DELIVERABLE UPON CONVERSION OF
THIS SECURITY AND THE ORDINARY SHARES REPRESENTED THEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
 (1)
REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS (A) A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) OR (B) NOT A U.S. PERSON AND LOCATED OUTSIDE THE UNITED STATES (WITHIN
THE MEANING OF REGULATION S UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT AND THAT IT AND ANY SUCH ACCOUNT IS NOT AN AFFILIATE OF MOMO INC. (THE “COMPANY”), AND 

  
 17 

 (2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL,
PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE
SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

(D) TO A NON-U.S. PERSON LOCATED OUTSIDE THE UNITED STATES IN ACCORDANCE WITH
REGULATION S UNDER THE SECURITIES ACT, OR 
 (E) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE). 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(E) ABOVE, THE COMPANY, THE DEPOSITARY AND
THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND
APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

  
 18 

 NO AFFILIATE (AS DEFINED IN RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY OR PERSON THAT
HAS BEEN AN AFFILIATE (AS DEFINED IN RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY DURING THE THREE IMMEDIATELY PRECEDING MONTHS MAY PURCHASE, OTHERWISE ACQUIRE OR OWN THIS NOTE OR A BENEFICIAL INTEREST HEREIN. 

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on
the Form of Assignment and Transfer has been checked. 
 Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like
tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Trustee in writing to so
surrender any Global Note as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Trustee shall so surrender such Global Note for exchange; and any new Global Note so
exchanged therefor shall not bear the restrictive legend specified in this Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the Resale
Restriction Termination Date and after a registration statement, if any, with respect to the Notes or the ADSs (including the Ordinary Shares represented thereby) issued upon conversion of the Notes has been declared effective under the Securities
Act. 
 Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global
Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a
beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(c). 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Bank of New York Mellon as
custodian for Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable
to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed
within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall execute, and
the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal
amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a
portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Note Registrar such Global Notes shall be canceled. 

  
 19 

 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Note Registrar. Upon execution and
authentication, the Note Registrar shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased, redeemed or transferred, such Global Note shall be,
upon receipt thereof, canceled by the Note Registrar in accordance with standing procedures and existing instructions of the Depositary. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes,
converted, canceled, repurchased, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in
accordance with the standing procedures and existing instructions of the Depositary, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Note Registrar, to reflect such reduction or
increase. 
 None of the Company, the Trustee, any agent of the Company or any agent of the Trustee shall have any responsibility or
liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

(d) Until the Resale Restriction Termination Date, any certificate representing ADSs (including the Ordinary Shares represented thereby)
issued upon conversion of such Note shall bear a legend in substantially the following form (unless the Note or such ADSs (including the Ordinary Shares represented thereby) has been transferred pursuant to a registration statement that has become
or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act,
or such ADS or the Ordinary Shares represented thereby have been issued upon conversion of Notes that have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues
to be effective at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 under the Securities Act or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company
with written notice thereof to the Note Registrar and any transfer agent for the ADSs): 
 THE AMERICAN DEPOSITARY SHARES EVIDENCED HEREBY
AND THE ORDINARY SHARES REPRESENTED THEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE
FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
 (1) REPRESENTS THAT IT AND
ANY ACCOUNT FOR WHICH IT IS ACTING IS (A) A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) OR (B) NOT A U.S. PERSON AND LOCATED OUTSIDE THE UNITED STATES (WITHIN THE MEANING OF
REGULATION S UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT AND THAT IT AND ANY SUCH ACCOUNT IS NOT AN AFFILIATE OF MOMO INC. (THE “COMPANY”), AND 

  
 20 

 (2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL,
PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SERIES OF NOTES UPON THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR
SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 

(A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

(D) TO A NON-U.S. PERSON LOCATED OUTSIDE THE UNITED STATES IN ACCORDANCE WITH
REGULATION S UNDER THE SECURITIES ACT, OR 
 (E) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE). 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (2)(E) ABOVE, THE COMPANY, THE DEPOSITARY AND
THE TRANSFER AGENT FOR THE COMPANY’S AMERICAN DEPOSITARY SHARES RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS
BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

  
 21 

 Any such ADSs as to which such restrictions on transfer shall have expired in accordance
with their terms may, upon surrender of the certificates representing such ADSs for exchange in accordance with the procedures of the transfer agent for the ADSs, be exchanged for a new certificate or certificates for a like aggregate number of
ADSs, which shall not bear the restrictive legend required by this Section 2.05(d). 
 (e) Any Note or ADS delivered upon the
conversion or exchange of any Note that is repurchased or owned by any Affiliate of the Company may not be resold by such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from, or in a transaction not subject
to, the registration requirements of the Securities Act in a transaction that results in such Note or ADS, as the case may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Company shall
cause any Note that is repurchased or owned by it to be surrendered to the Note Registrar for cancellation in accordance with Section 2.08. 

(f) Until the Resale Restriction Termination Date, prior to any sale of Regulation S Notes, the ADSs deliverable upon conversion thereof or
the Ordinary Shares represented thereby, to a qualified institutional buyer in compliance with Rule 144A, the Holder thereof shall deliver to the Trustee, Transfer Agent and/or Depositary, as the case may be, written confirmation that the
prospective purchaser is a Person such Holder reasonably believes is a “qualified institutional buyer” (within the meaning of Rule 144A) that is purchasing for its own account or for the account of another qualified institutional buyer and
to whom notice is given that the transfer is being made in reliance on Rule 144A. 
 Section 2.06. Mutilated, Destroyed, Lost or
Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee shall authenticate and deliver, a new Note, bearing a registration number
not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company and
to the Trustee such security and/or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

The Trustee may authenticate any such substituted Note and deliver the same upon the receipt of such security and/or indemnity as the Trustee
and the Company may require. No service charge shall be imposed by the Company, the Transfer Agent, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but
the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp, issue, transfer or similar tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name
of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 14
shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof
except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company and to the Trustee such security and/or indemnity as may be required by them to save each of them harmless for
any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, and the Trustee evidence of their satisfaction of the destruction, loss or
theft of such Note and of the ownership thereof. 

  
 22 

 Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue
of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of
(but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the replacement, payment, redemption, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law
or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, conversion or repurchase of negotiable instruments or other securities without their surrender. 

Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee shall, upon
written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions,
insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee upon the same conditions and in substantially
the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any
Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal
amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same
limitations under this Indenture as Physical Notes authenticated and delivered hereunder. 
 Section 2.08. Cancellation of Notes
Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than the Note Registrar (including any
of the Company’s agents, Subsidiaries or Affiliates), to be delivered and surrendered to the Note Registrar for cancellation. All Notes delivered to the Note Registrar shall be canceled promptly by it, and no Notes shall be authenticated in
exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Note Registrar shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate of
such cancellation and disposition to the Company, at the Company’s written request in a Company Order. 

  
 23 

 Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such 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 Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the
Trustee in writing of any change in the “CUSIP” numbers. Prior to the Notes Fungibility Date, the Rule 144A Notes and the Regulation S Notes shall have different “CUSIP” numbers. Following the Notes Fungibility Date, the Rule
144A Notes and the Regulation S Notes shall have the same “CUSIP” number. 
 Section 2.10. Additional Notes; Repurchases.
The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (except for any differences in the
issue price, the issue date and interest accrued, if any) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax or
securities law purposes, such additional Notes shall have a separate CUSIP number from both the Rule 144A Notes and the Regulation S Notes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order,
an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.06, as the Trustee shall reasonably request. In addition, the
Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or through its Subsidiaries or
through a private or public tender or exchange offer or through counterparties to private agreements. The Company shall cause any Notes so repurchased to be surrendered to the Note Registrar for cancellation in accordance with Section 2.08. The
Company may also enter into cash-settled swaps or other derivatives with respect to the Notes. For the avoidance of doubt, any Notes underlying such cash-settled swaps or other derivatives shall not be required to be surrendered to the Note
Registrar for cancellation in accordance with Section 2.08 and will continue to be considered outstanding for purposes of this Indenture, subject to the provisions of Section 8.04. 

ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officers’
Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore authenticated and
delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Note Registrar for cancellation; or (ii) the Company has deposited with the Paying
Agent or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, a Redemption Date, the Repurchase Date, any Fundamental Change Repurchase Date, 

upon conversion or otherwise, cash or cash and ADSs, if any (solely to satisfy the Company’s Conversion Obligation, if applicable), sufficient to pay all
of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and (b) 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 7.06 shall survive. 

  
 24 

 ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal
(including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and
in the Notes. 
 Section 4.02. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City
of New York, an office or agency (which will be the Corporate Trust Office initially) where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for
conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes 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 or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 

The Company may also from time to time designate as co-Note Registrars one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, 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. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

The Company hereby initially designates The Bank of New York Mellon as the Paying Agent, Note Registrar and Conversion Agent and the Corporate
Trust Office and the office or agency of The Bank of New York Mellon in the Borough of Manhattan, The City of New York, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 

Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy
in the office of Trustee, will appoint, in the manner provided in Section 7.09, a trustee, so that there shall at all times be a trustee hereunder. 

  
 25 

 Section 4.04. Provisions as to Paying Agent. (a) If the Company shall
appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price, the
Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes for the benefit of the Holders of the Notes; 

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including
the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and 

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held. 
 The Company shall, on or before each due date of the principal (including the Redemption Price, the Repurchase
Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Redemption Price, the Repurchase Price and the
Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that such deposit must
be received by the Paying Agent by 10:00 a.m., New York City time, one Business Day prior to the relevant due date. The Paying Agent shall not be bound to make any payment until it has received, in immediately available and cleared funds, an amount
which shall be sufficient to pay, as applicable, the aggregate amount of principal (including Repurchase Price and Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when such principal or interest
shall become due and payable. The Paying Agent shall not be responsible or liable for any delay in making the payment if it does not receive funds before 10:00 a.m. one Business Day prior to the payment date. 

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price,
the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such
principal (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such
action and of any failure by the Company to make any payment of the principal (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the
same shall become due and payable. 

  
 26 

 (c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at
any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held by the Company in trust or by any Paying Agent as required by
this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all
further liability but only with respect to such sums or amounts. 
 (d) Any money and ADSs deposited with the Trustee or any Paying Agent,
or then held by the Company, in trust for the payment of principal (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, any Note (or, in the case of
ADSs, in satisfaction of the Conversion Obligation) and remaining unclaimed for two years after such principal (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) or interest has become
due and payable shall be paid or delivered, as the case may be, to the Company on request of the Company contained in an Officers’ Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note
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 money and ADSs, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment or delivery, may at the expense of the Company cause to be published once, in a newspaper published in the
English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such money and ADSs remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of such money and ADSs then remaining will be repaid or delivered to the Company. 

Section 4.05. Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence. 
 Section 4.06. Rule 144A Information Requirement and Annual Reports.
(a) At any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes, any ADSs deliverable upon conversion thereof or any Ordinary Shares underlying ADSs deliverable upon
conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon written request, provide to any Holder, beneficial
owner or prospective purchaser of such Notes or the ADSs deliverable upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or ADSs pursuant
to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of such Notes or such ADSs may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or
ADSs in accordance with Rule 144A, as such rule may be amended from time to time. 
 (b) The Company shall provide to the Trustee within 15
days after the same are required to be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any applicable
grace period provided by Rule 12b-25 under the Exchange Act). 

  
 27 

 (c) Delivery of the reports and documents described in subsection (b) above to the
Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). 

(d) If, at any time during the six-month period beginning on, and including, the date that is six
months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after
giving effect to all applicable grace periods thereunder and other than reports on Form 6-K), or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that
were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the
Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or
the period during which the Notes are not freely tradable, as the case may be. As used in this Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of
the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act. 

(e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed, the Notes are assigned
a restricted CUSIP or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions
pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 370th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the
principal amount of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes have been assigned an unrestricted CUSIP and the Notes are freely tradable by Holders other than the
Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes). 

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on
the Notes. 
 (g) The Additional Interest that is payable in accordance with Section 4.06(d) or Section 4.06(e) shall be in
addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. In no event shall Additional Interest accrue on any day under the terms of this Indenture (taking
any Additional Interest payable pursuant to Section 4.06(d) and Section 4.06(e) together with any Additional Interest payable pursuant to Section 6.03) at an annual rate in excess of 0.50%, in the aggregate, for any violation or
Default caused by the Company’s failure to be current in respect of its Exchange Act reporting obligations. 

  
 28 

 (h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or
Section 4.06(e), the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable.
Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid such Additional Interest
directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 

Section 4.07. Additional Amounts. (a) All payments and deliveries made by, or on behalf of, the Company or any successor to
the Company under or with respect to this Indenture and the Notes, including, but not limited to, payments of principal (including, if applicable, the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price), payments of
interest and deliveries of ADSs (together with payments of cash for any Fractional ADS) upon conversion of the Notes, shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or

therein), unless such withholding or deduction is required by law or by regulation or governmental policy having the force of law. In the event that any such withholding or deduction is so required, the Company or any successor to the Company shall
pay to each Holder such additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by the Holder after such withholding or deduction (and after deducting any taxes on the Additional Amounts)
shall equal the amounts that would have been received by such Holder had no such withholding or deduction been required; provided that no Additional Amounts shall be payable: 

(i) for or on account of: 

(A) any tax, duty, assessment or other governmental charge that would not have been imposed but for: 

(1) the existence of any present or former connection between the Holder or beneficial owner of such Note and the Relevant
Jurisdiction, other than merely holding such Note or the receipt of payments thereunder, including, without limitation, such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Jurisdiction or treated
as a resident thereof or being or having been physically present or engaged in a trade or business therein or having had a permanent establishment therein; 

(2) the presentation of such Note (in cases in which presentation is required) more than 30 days after the later of the date

Fractional ADS) upon conversion of such Note became due and payable pursuant to the terms thereof or was made or duly provided for; 

  
 29 

 (3) the failure of the Holder or beneficial owner to comply with a timely
request from the Company or any successor of the Company, addressed to the Holder, to provide certification, information, documents or other evidence concerning such Holder’s or beneficial owner’s nationality, residence, identity or
connection with the Relevant Jurisdiction, or to make any declaration or satisfy any other reporting requirement relating to such matters, if and to the extent that due and timely compliance with such request is required by statute, regulation or
administrative practice of the Relevant Jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable; or 

(4) the presentation of such Note (in cases in which presentation is required) for payment in the Relevant Jurisdiction,
unless such Note could not have been presented for payment elsewhere; 
 (B) any estate, inheritance, gift, sale, transfer,
excise, personal property or similar tax, assessment or other governmental charge; 
 (C) any tax, duty, assessment or other
governmental charge that is payable otherwise than by withholding from payments or deliveries under or with respect to the Notes; 

(D) any tax required to be withheld or deducted under Sections 1471 to 1474 of the Code (or any amended or successor versions
of such Sections) (“FATCA”), any regulations or other official guidance thereunder, any intergovernmental agreement entered into in connection with FATCA, or any law, regulation or other official guidance enacted in any jurisdiction
implementing FATCA or an intergovernmental agreement; or 
 (E) any combination of taxes, duties, assessments or other
governmental charges referred to in the preceding clauses (A), (B), (C) or (D); or 
 (ii) with respect to any payment of the
principal of (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) and interest on such Note or the delivery of ADSs (together with payment of cash for any Fractional ADS) upon conversion
of such Note to a Holder, if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment to the extent that such payment would be required to be included in the income under the laws of the Relevant
Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a partner or member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor,
partner, member or beneficial owner been the Holder thereof. 

  
 30 

 (b) Any reference in this Indenture or the Notes in any context to the delivery of ADSs
(together with payments of cash for any Fractional ADS) upon conversion of the Notes or the payment of principal of (including the Redemption Price, the Repurchase Price and Fundamental Change Repurchase Price, if applicable) and interest on, any
Note or any other amount payable with respect to such Note, shall be deemed to include payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable with respect to that amount pursuant to this
Section 4.07. 
 (c) If the Company or its successor is required to make any deduction or withholding from any payments or deliveries
with respect to the Notes, it will deliver to the Trustee official tax receipts evidencing the remittance to the relevant tax authorities of the amounts so withheld or deducted. 

(d) The foregoing obligations shall survive termination or discharge of this Indenture. 

Section 4.08. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not
at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or
interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, 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. 
 Section 4.09. Compliance Certificate; Statements as to Defaults. The Company
shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2016) an Officers’ Certificate stating that a review has been conducted of the
Company’s activities under this Indenture and the Company has fulfilled its obligations hereunder, and whether the authorized Officers thereof have knowledge of any Default by the Company that occurred during the previous year that is then
continuing and, if so, specifying each such Default and the nature thereof. 
 In addition, the Company shall deliver to the Trustee, as
soon as possible, and in any event within 30 days after the Company becomes aware of the occurrence of any Default if such Default is then continuing, an Officers’ Certificate setting forth the details of such Default, its status and the action
that the Company is taking or proposing to take in respect thereof. The Trustee shall have no responsibility to take any steps to ascertain whether any Event of Default or Default has occurred, and until (i) a Responsible Officer of the Trustee
has received an Officers’ Certificate regarding such an occurrence, or (ii) the Trustee has received notice from the Holders of at least 25% in aggregate principal amount of the Notes then outstanding regarding such an occurrence, the
Trustee is entitled to assume, without liability, that no Event of Default or Default has occurred. 

  
 31 

 Section 4.10. Further Instruments and Acts. The Company will execute and deliver
such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

 LISTS
OF HOLDERS AND REPORTS BY THE COMPANY AND THE TRUSTEE

(g) default by the Company or any Significant Subsidiary of the Company with respect to any mortgage, agreement or other instrument under
which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of US$40 million (or the foreign currency equivalent thereof) in the aggregate of the Company and/or any such
Significant Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any

custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days. 

Section 6.02. Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing
(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), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of
the Notes shall have already become due and payable, the Trustee may by notice in writing to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by
notice in writing to the Company and to the Trustee may, and the Trustee at the request of such Holders accompanied by security and/or indemnity reasonably satisfactory to the Trustee shall, declare 100% of the principal of, and accrued and unpaid
interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, notwithstanding anything contained in this Indenture or in the Notes to the
contrary. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid interest on, all
Notes shall become and shall automatically be immediately due and payable without any action on the part of the Trustee. If an Event of Default occurs and is continuing, all agents of the Company appointed under this Indenture will be required to
act on the direction of the Trustee. 

  
 33 

 The immediately preceding paragraph, however, is subject to the conditions that if, at any
time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of
accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate per annum borne by the Notes plus one percent) and amounts due to the Trustee pursuant to
Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of
and accrued and unpaid interest on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence)
the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration
and its consequences and 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 or rescission and annulment shall extend to or shall
affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of
Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the
consideration due upon conversion of the Notes. 
 Section 6.03. Additional Interest. Notwithstanding anything in this Indenture
or in the Notes to the contrary, to the extent the Company elects, the sole remedy for Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall after the occurrence of such an
Event of Default consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to: 
 (a) 0.25% per annum of
the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such an Event of Default first occurs and ending on the earlier of (i) the date on which such Event of Default is cured
or validly waived and (ii) the 90th day immediately following, and including, the date on which such Event of Default first occurred; and 

  
 34 

 (b) if such Event of Default has not been cured or validly waived prior to the 91st day
immediately following, and including, the date on which such Event of Default first occurred, 0.50% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the 91st day immediately
following, and including, the date on which such an Event of Default first occurred and ending on the earlier of (i) the date on which such Event of Default is cured or validly waived and (ii) the 180th day immediately following, and
including, the date on which such Event of Default first occurred. 
 Interest payable pursuant to this Section 6.03 shall be in
addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). In no event shall Additional Interest accrue on the Notes on any day under this Indenture (taking any Additional Interest payable
pursuant to this Section 6.03 together with any Additional Interest payable pursuant to Section 4.06(d) and Section 4.06(e)) at an annual rate accruing in excess of 0.50%, in the aggregate, for any violation or Default caused by the
Company’s failure to be current in respect of its Exchange Act reporting obligations. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 181st
day after such Event of Default (if the Event of Default with respect to the Company’s obligations under Section 4.06(b) is not cured or waived prior to such 181st day), the Notes will be subject to acceleration as provided in
Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment but does not pay the Additional Interest when
due, the Notes shall be subject to acceleration as provided in Section 6.02. 
 In order to elect to pay Additional Interest as the
sole remedy during the first 180 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of such election prior
to the beginning of such 180-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 

Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of
Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee acting in its own discretion or at the request of Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with
Section 8.04 and subject to indemnity and/or security reasonably satisfactory to the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if
any, with interest on any overdue principal and interest, if any, at the rate per annum borne by the Notes at such time plus one percent, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the
Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or any other obligor upon the Notes, wherever situated. 

  
 35 

 In the event there shall be pending proceedings for the bankruptcy or for the reorganization
of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall
have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or
to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and
accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have
the claims of the Trustee (including any claim for the compensation, reasonable expenses, reasonable disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company
or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due
to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as
administrative expenses, 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 to it for compensation, reasonable expenses, advances and reasonable
disbursements, including agents and counsel fees and expenses, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of compensation,
reasonable expenses, advances and reasonable disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends,
monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

Nothing herein contained 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 such Holder 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. 

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the
possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or 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 compensation, reasonable expenses, reasonable disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 

  
 36 

 In any proceedings brought by the Trustee (and in any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such
proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been
discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case
the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the
Trustee shall continue as though no such proceeding had been instituted. 
 Section 6.05. Application of Monies Collected by
Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the
several Notes, and stamping thereon 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 7.06 and any payments due to the Paying Agent, the Transfer Agent, the Conversion Agent and the Note Registrar; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, the
Notes in default in the order of the date due of the payments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate per annum borne by the Notes at such time
(including, without duplication, any additional interest on such overdue payments pursuant to Section 6.04), such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any,
with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate per annum borne by the Notes at such time plus one percent, and in case such
monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price and the
cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to
the aggregate of such principal (including, if applicable, the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price) and accrued and unpaid interest; and 

Fourth, to the payment of the remainder, if any, to the Company. 

  
 37 

 Section 6.06. Proceedings by Holders. Except to enforce the right to receive
payment of principal (including, if applicable, the Redemption Price, the Repurchase Price or Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder
of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver,
trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously shall
have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 
 (b) Holders of at
least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

(c) such Holders shall have offered to the Trustee such security and/or indemnity reasonably satisfactory to it against any loss, liability or
expense to be incurred therein or thereby; 
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of security
and/or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 
 (e) no direction that, in the
opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such
60-day period pursuant to Section 6.09, 
 it being understood and intended, and being expressly covenanted by
the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common
benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder to receive payment or delivery,
as the case may be, of (x) the principal (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest on, and (z) the consideration due upon
conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective
dates against the Company shall not be impaired or affected without the consent of such Holder. 

  
 38 

 Section 6.07. Proceedings by Trustee. In case of an Event of Default, the
Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law
or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable
right vested in the Trustee by this Indenture or by law. 
 Section 6.08. Remedies Cumulative and Continuing. Except as provided
in the last paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and
remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of
any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence
therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or
by the Holders. 
 Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a
majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 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 Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may
take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that would involve the Trustee in personal liability, or if it is not provided with security and/or
indemnity to its reasonable satisfaction. In addition, the Trustee will not be required to expend its own funds under any circumstances. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest on, or the principal
(including, if applicable, the Redemption Price, Repurchase Price or Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (ii) a failure by the Company to pay or
deliver, or cause to be delivered, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent
of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the
Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

  
 39 

 Section 6.10. Notice of Defaults and Events of Default. If a Default or Event of
Default occurs and is continuing and is notified in writing to the Trustee, the Trustee shall, within 90 days after the occurrence and continuance of such Default or Event of Default, mail to all Holders (at the Company’s expense) as the names
and addresses of such Holders appear upon the Note Register, notice of all Defaults so notified in writing, unless such Defaults shall have been cured or waived before the giving of such notice; provided that the Trustee shall not be deemed
to have knowledge of any occurrence of a Default or Event unless it has received written notice. Except in the case of a Default in the payment of the principal of (including the Redemption Price, the Repurchase Price and the Fundamental Change
Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the
Trustee’s board of directors, an executive committee or a committee of Responsible Officers of the Trustee (in its sole discretion) in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess costs, including attorneys’ fees and reasonable expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of or accrued and unpaid interest on any Note (including, but not limited to, the Redemption Price and the Repurchase Price and Fundamental Change Repurchase Price with respect to the Notes being
repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 14. 

ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the
curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations will be read into the Indenture against
the Trustee. In case an Event of Default has occurred that has not been cured or waived the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent
person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or
powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity and/or security reasonably satisfactory to it against the costs, liabilities or reasonable expenses that might be
incurred by it in compliance with such request or direction. 

  
 40 

 No provision of this Indenture shall be construed to relieve the Trustee from liability for
its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the
occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this
Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the
absence of bad faith on the part of the Trustee, the Trustee may conclusively and without liability rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine
the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts, statements, opinions or conclusions stated therein); 

(b) the Trustee shall not be liable for any error of judgment made in good faith by an Officer of the Trustee, unless it shall be proved that
the Trustee was grossly negligent in ascertaining the pertinent facts; 
 (c) the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 8.04 relating
to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 

(d) whether or not therein 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; 
 (e) the Trustee shall not be liable in respect of any
payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note
Registrar with respect to the Notes; 

  
 41 

 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant
to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively and without liability rely on its failure to receive such notice as reason to act as if no such event occurred; 

(g) [RESERVED] 
 (h) in
the event that the Trustee is also acting as Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the rights, immunities, privileges, disclaimers from liability and protections (including the right to compensation and
indemnity) afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Note Registrar, Paying Agent, Conversion Agent or transfer agent; 

(i) the Trustee shall have no duty to inquire, no duty to determine and no duty to monitor as to the performance of the Company’s
covenants in this Indenture or the financial performance of the Company; the Trustee shall be entitled to assume, until it has received written notice in accordance with this Indenture, that the Company is properly performing its duties hereunder;

 (j) the Trustee shall be under no obligation to enforce any of the provisions of this Indenture unless it is instructed by Holders of at
least 25% of the aggregate principal amount of outstanding Notes and is provided with security and/or indemnity reasonably satisfactory to it;

delivered at the cost of the Company conforming to Section 17.06 and the Trustee and the Agents may rely conclusively on such certificate or opinion and will not be liable for any action it takes or omits to take in good faith in reliance on
such Officers’ Certificate or Opinion of Counsel; 
 (l) in connection with the exercise by it of its trusts, powers, authorities or
discretions (including, without limitation, any modification, waiver, authorization or determination), the Trustee shall have regard to the general interests of the Holders as a class but shall not have regard to any interests arising from
circumstances particular to individual Holders (whatever their number) and in particular, but without limitation, shall not have regard to the consequences of the exercise of its trusts, powers, authorities or discretions for individual Holders
(whatever their number) resulting from their being for any purpose domiciled or resident in, or otherwise connected with, or subject to the jurisdiction of, any country, state or territory; and 

(m) the Trustee is not obliged to do or omit to do anything which in its reasonable opinion, would or may be illegal or would constitute a
breach of any fiduciary duty or duty of confidentiality, or any law, rule, regulation, or any decree, order or judgment of any court, or practice, request, direction, notice, announcement or similar action (whether or not having the force of law) of
any relevant government, government agency, regulatory authority, stock exchange or self-regulatory organization to which the Trustee is subject. The Trustee may without liability to do anything which is, in its reasonable opinion, necessary to
comply with any such law, directive or regulations. 

  
 42 

 None of the provisions contained in this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 

Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01: 

(a) the Trustee may conclusively and without liability rely and shall be fully protected in acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond, Note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 

(b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers’ Certificate
(unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; 

(c) the Trustee may consult with counsel and require an Opinion of Counsel and any advice of such counsel or Opinion of Counsel shall be full
and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(d) 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 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,

 (f) the permissive rights of the Trustee enumerated herein shall
not be construed as duties; 
 (g) under no circumstances and notwithstanding any contrary provision included herein, neither the Trustee,
the Paying Agent, the Conversion Agent nor the Note Registrar shall be responsible or liable for special, indirect, punitive, or consequential damages or loss of any kind whatsoever (including, but not limited to, loss of profit) irrespective of
whether any of them have been advised of the likelihood of such loss or damage and regardless of the form of action; this provision shall remain in full force and effect notwithstanding the discharge of the Notes, the termination of this Indenture
or the resignation, replacement or removal of the Trustee, the Paying Agent, the Conversion Agent and the Note Registrar; and 

  
 43 

 (h) the Trustee, the Paying Agent, the Conversion Agent and the Note Registrar may refrain
from taking any action in any jurisdiction if the taking of such action in that jurisdiction would, in its opinion based upon legal advice in the relevant jurisdiction, be contrary to any law of that jurisdiction or, to the extent applicable, of New
York; furthermore, the Trustee may also refrain from taking such action if it would otherwise render it liable to any person in that jurisdiction or New York or if, in its opinion based on such legal advice, it would not have the power to do the
relevant thing in that jurisdiction by virtue of any applicable law in that jurisdiction or in New York or if it is determined by any court or other competent authority in that jurisdiction that it does not have such power. 

(i) The Company understands that The Bank of New York Mellon Corporation is a global financial organization that operates in and provides
services and products to clients through its affiliates, branches, representative offices and/or subsidiaries located in multiple jurisdictions (collectively, the “BNY Mellon Group” and each a “BNY Mellon Entity”).
The BNY Mellon Group may: (i) use and/or centralize in one or more BNY Mellon Entity in connection with its performance of the functions, duties and services provided and any other obligations under this Indenture and/or the Notes and in
certain other activities (the “Centralized Functions”), including, without limitation, audit, accounting, tax, administration, risk management, credit, legal, compliance, operation, sales and marketing, product communication,
relationship management, information technology, records and data storage, performance measurement, data aggregation and the compilation and analysis of information and data regarding the Company (which, for purposes of this sub-Section 7.02(i), includes the name and business contact information for the employees and representatives of the Company and any personal data) and the accounts established pursuant to the transactions
contemplated in this Indenture and/or the Notes (“Client Information”); and (ii) use third party service providers to store, maintain and process Client Information (“Outsourced Functions”). Notwithstanding
anything to the contrary contained elsewhere in this Indenture and/or the Notes and solely in connection with the Centralized Functions and/or Outsourced Functions, the Company consents to the: (i) collection, use and storage of, and authorizes
the BNY Mellon Group to collect, use and store, Client Information within and outside of any jurisdiction, including without limitation Australia, the European Economic Area, Hong Kong, the PRC, Japan, Singapore, India, the British Virgin Islands
and the United States of America; and (ii) disclosure of, and authorizes the BNY Mellon Group to disclose, Client Information to: (A) any other BNY Mellon Entity (and their respective officers, directors and employees); and
(B) third-party service providers (but solely in connection with Outsourced Functions) who are required to maintain the confidentiality of Client Information. In addition, the BNY Mellon Group may aggregate Client Information with other data
collected and/or calculated by the BNY Mellon Group, and the BNY Mellon Group will own all such aggregated data, provided that the BNY Mellon Group shall not distribute the aggregated data in a format that identifies Client Information with the
Company specifically. The Company represents to the BNY Mellon Group that it is authorized to consent to the foregoing and that the disclosure of Client Information in connection with the Centralized Functions and/or Outsourced Functions does not
violate any relevant data protection legislation. The Company also consents to the disclosure of Client Information to governmental, tax, regulatory, law enforcement and other authorities in jurisdictions where the BNY Mellon Group operates and
otherwise as required by law, rule, or guideline (including any tax and swap trade data reporting regulations). 

  
 44 

 Section 7.03. No Responsibility for Recitals, Etc. The recitals, statements,
warranties and representations contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same.
The Trustee makes no representations as to the accuracy or correctness of the same or the execution, legality, effectiveness, adequacy, genuineness, validity, enforceability or admissibility in evidence of this Indenture or of the Notes. The Trustee
shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. Notwithstanding the generality of the
foregoing, each Holder shall be solely responsible for making its own independent appraisal of, and investigation into, the financial condition, creditworthiness, condition, affairs, status and nature of the Company, and the Trustee shall not at any
time have any responsibility for the same and each Holder shall not rely on the Trustee in respect thereof. 
 Section 7.04.
Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same
rights it would have if it were not the Trustee, Paying Agent, Conversion Agent or Note Registrar, and nothing herein shall obligate any of them to account for any profits earned from any business or transactional relationship. 

Section 7.05. Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied as herein provided, be
held in trust for the purposes for which they were received. Money held by the Trustee in trust or by the Paying Agent hereunder need not be segregated from other funds except to the extent required by law. Neither the Trustee nor the Paying Agent
shall be under any liability for interest on any money received by it hereunder. 
 Section 7.06. Compensation and Expenses of
Trustee. (a) The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the compensation and the reasonable expenses and disbursements of its agents and
counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its gross negligence or willful misconduct. The Company also covenants to indemnify the Trustee in any capacity
under this Indenture and any other document or transaction entered into in connection herewith, and to hold it harmless against, any loss, claim, damage, liability or expense incurred without gross negligence or willful misconduct on the part of the
Trustee, its officers, directors, agents or employees, as the case may be, and arising out of or in connection with the acceptance or administration of this Indenture or in any other capacity hereunder, including the costs and expenses of defending
themselves against any claim of liability in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be
secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of
particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The indemnity under this Section 7.06(a) is payable
upon demand by the Trustee. The obligation of the Company under this Section 7.06(a) shall survive the satisfaction and discharge of the Notes, the termination or discharge of this Indenture and the resignation, replacement or removal or the
Trustee. The indemnification provided in this Section 7.06(a) shall extend to the officers, directors, agents and employees of the Trustee. Subject to Section 7.02(e), any negligence or misconduct of any agent, delegate, attorney or
representative, in each case, of the Trustee, shall not affect indemnification of the Trustee. 

  
 45 

 Without prejudice to any other rights available to the Trustee under applicable law, when
the Trustee and its agents incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws. If a Default or Event of Default shall have occurred or if the Trustee finds it expedient or necessary or is requested by the Company and/or the Holders to undertake duties which are
of an exceptional nature or otherwise outside the scope of the Trustee’s normal duties under this Indenture, the Company will pay such additional remuneration as the Company and the Trustee may separately agree in writing. 

(b) The Paying Agent, the Conversion Agent and the Note Registrar shall be entitled to the compensation to be agreed upon in writing with the
Company for all services rendered by it under this Indenture, and the Company agrees promptly to pay such compensation and to reimburse the Paying Agent, the Conversion Agent and the Note Registrar for its out-of-pocket expenses (including fees and reasonable expenses of counsel) incurred by it in connection with the services rendered by it under this Indenture. The Company hereby agrees to indemnify the Paying
Agent, the Conversion Agent and the Note Registrar and their respective officers, directors, agents and employees and any successors thereto for, and to hold it harmless against, any loss, liability or expense (including fees and reasonable expenses
of counsel) incurred without gross negligence or willful misconduct on its part arising out of or in connection with its acting as the Paying Agent, the Conversion Agent and the Note Registrar hereunder. The obligations of the Company under this
paragraph (b) shall survive the payment of the Notes, the termination or discharge of the Indenture and the resignation, replacement or removal of the Paying Agent, the Conversion Agent and the Note Registrar. 

Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate shall be full warrant to the Trustee for any action taken or
omitted by it under the provisions of this Indenture upon the faith thereof. 

  
 46 

 Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee
hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least US$50,000,000. If such Person publishes reports of condition at least annually, pursuant to law
or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee 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 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving 60 days written notice of
such resignation to the Company and by mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written
instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may appoint a successor trustee on behalf of and at the expense of the Company or it may petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of himself or herself and all others
similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

(b) In case at any time any of the following shall occur: 

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign
after written request therefor by the Company or by any such Holder, or 
 (ii) 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 either case, the Company may by a Board Resolution remove the Trustee and appoint a successor
trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of
Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

  
 47 

 (c) The Holders of a majority in aggregate principal amount of the Notes at the time
outstanding, as determined in accordance with Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such
nomination the Company objects thereto, in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a
successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions
of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 

Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due to it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the
benefit of Holders of particular Notes, to secure any amounts then due to it pursuant to the provisions of Section 7.06. 
 No
successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at
the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders at their addresses as they shall appear on the Note Register. If the Company fails to mail
such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 

Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate
trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided
that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08. 

  
 48 

 In case at the time such successor to the Trustee shall succeed to the trusts created by
this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that
time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any
predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 7.12. Trustee’s Application for Instructions from the Company. Any application by the Trustee for written
instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in
writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or
omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer that the Company has indicated
to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any
omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 

ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (b) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders.
Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining Holders
entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 

  
 49 

 Section 8.02. Proof of Execution by Holders. Subject to the provisions of
Section 7.01, Section 7.02 and Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the
Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall be proved in the manner provided in
Section 9.06. 
 Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any Paying Agent, any Conversion
Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation
of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued and unpaid interest on such
Note, for the purpose of conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All such
payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or ADSs so paid or delivered, effectual to satisfy and discharge the liability for monies payable or ADSs deliverable
upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent,
solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture. 

Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of
Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary or Consolidated Affiliated Entity thereof or by any Affiliate of the Company or any Subsidiary or
Consolidated Affiliated Entity thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any
such direction, consent, waiver or other action only Notes in respect of which a Responsible Officer is notified in writing shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes
of this Section 8.04 if the pledgee shall establish its right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary or Consolidated Affiliated Entity thereof or an Affiliate of the Company or a Subsidiary or
Consolidated Affiliated Entity thereof. Within five days of acquisition of the Notes by any of the above described persons or entities, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all
Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of
the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

  
 50 

 Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action,
any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any
Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of
transfer thereof.

proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 8.04, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each
US$1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting
to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of
Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not
constituting a quorum, and the meeting may be held as so adjourned without further notice. 
 Minutes shall be made of all resolutions and
proceedings at every meeting and, if purporting to be signed by the chairman of that meeting or of the next succeeding meeting of Holders of the Notes, shall be conclusive evidence of the matters in them. Until the contrary is proved every meeting
for which minutes have been so made and signed shall be deemed to have been duly convened and held and all resolutions passed or proceedings transacted at it to have been duly passed and transacted. 

  
 52

thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the principal amount of the

 Section 9.07. No Delay of Rights by Meeting. Nothing
contained in this Article 9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any

 Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise. The Trustee shall be entitled to seek an Officers’ Certificate and an Opinion of Counsel, at the Company’s expense, that any such supplemental indenture is
authorized and permitted by the terms of this Indenture and not contrary to law. 
 Any supplemental indenture authorized by the provisions
of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the

immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

sufficient if such Holders approve the substance thereof. After any supplemental indenture becomes effective under Section 10.01 or Section 10.02, the Company shall mail to the Holders a notice briefly describing such supplemental
indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the

 ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, the Company shall
not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless:

organized and existing under the laws of the Cayman Islands, the British Virgin Islands, Bermuda or Hong Kong and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company
under the Notes and this Indenture (including, for the avoidance of doubt, the obligation to pay Additional Amounts pursuant to Section 4.07); and 

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this
Indenture. 
 For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties
and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a
consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 11.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on
all of the Notes (including, for the avoidance of doubt, any Additional Amounts), the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes (including, for the avoidance of doubt, any
Additional Amounts) and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all
or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and
may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead
of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and
delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of
any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in the first paragraph of this Indenture (or any successor that shall
thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of
the Notes and from its obligations under this Indenture and the Notes. 

  
 56 

 In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes
in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 

Section 11.03. Opinion of Counsel to Be Given to Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be
effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental
indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11. 

ARTICLE 12 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND
DIRECTORS 
 Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the
principal of or accrued and unpaid interest on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental
indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company
or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

Section 14.01. Conversion Privilege. Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note
shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is US$1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the close of business on the second
Business Day immediately preceding the Maturity Date into ADSs at an initial conversion rate of 15.4776 ADSs (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per US$1,000 principal amount of Notes
(subject to the settlement provisions of Section 14.02, the “Conversion Obligation”). 

  
 57 

 Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Upon conversion of any Note, the Company shall cause to be delivered to the converting Holder, in respect of each US$1,000 principal
amount of Notes being converted, a number of ADSs equal to the Conversion Rate, together with a cash payment, if applicable, in lieu of any fractional ADSs (“Fractional ADSs”) (assuming delivery of the maximum number of ADSs due
upon conversion that do not represent a fractional ADS) in accordance with subsection (j) of this Section 14.02, on the third Business Day immediately following the relevant Conversion Date. For the avoidance of doubt, neither the Trustee
nor any Agent shall have any responsibility to deliver ADSs to any person or deal with cash payments in relation to conversions, except for cash payments in lieu of any fractional ADS. 

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall
(i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in
Section 14.02(h), and complete, manually sign and deliver a duly completed irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) and
(ii) in the case of a Physical Note (1) complete, manually sign and deliver a duly completed irrevocable Notice of Conversion to the Conversion Agent at the specified office of the Conversion Agent and state in writing therein the
principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any ADSs to be delivered upon settlement of the Conversion Obligation to be registered,
(2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the specified office of the Conversion Agent, (3) if required, furnish appropriate endorsements and
transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall
notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be delivered and no Notes may be surrendered by a Holder for conversion thereof if
such Holder has also delivered a Repurchase Notice or Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Repurchase Notice or Fundamental Change Repurchase Notice in accordance with
Section 15.03. A Notice of Conversion shall be deposited in duplicate at the office of any Conversion Agent on any Business Day from 9:00 a.m. to 3:00 p.m. at the location of the Conversion Agent to which such Notice of Conversion is delivered.
Any Notice of Conversion and any Physical Note (if issued) deposited outside the hours specified or on a day that is not a Business Day at the location of the Conversion Agent shall for all purposes be deemed to have been deposited with that
Conversion Agent between 9:00 a.m. and 3:00 p.m. on the next Business Day. 

  
 58 

 If more than one Note shall be surrendered for conversion at one time by the same Holder,
the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. None of the Agents of the Trustee
shall have any responsibility whatsoever with respect to the issuance and delivery of the ADSs to the converting Holder. 
 (c) A Note shall
be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. The Company shall issue or
cause to be issued, and deliver or cause to be delivered to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of ADSs to which such Holder shall be entitled in
satisfaction of the Company’s Conversion Obligation. 
 (d) In case any Note shall be surrendered for partial conversion, the Company
shall execute and instruct the Trustee who shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or
that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp, issue, transfer or similar tax due on the
delivery of the ADSs upon conversion of the Notes (or the issuance of the underlying Ordinary Shares), unless the tax is due because the Holder requests such ADSs (or such Ordinary Shares) to be issued in a name other than the Holder’s name, in
which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the ADSs (or the Ordinary Shares) being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient
to pay any tax that is due by such Holder in accordance with the immediately preceding sentence. The Company shall pay the ADS Depositary’s fees for issuance of the ADSs. 

(f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any ADSs delivered upon the conversion of any Note
as provided in this Article 14. 
 (g) Upon the conversion of an interest in a Global Note, the Trustee shall make a notation on such Global
Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 

  
 59 

 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and
unpaid interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but
not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding
the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the
corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date
must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity
Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the Business Day immediately succeeding the corresponding Interest Payment Date (or, if such Interest Payment Date is not a Business
Day, the second Business Day immediately succeeding such Interest Payment Date); (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately succeeding the
corresponding Interest Payment Date (or, if such Interest Payment Date is not a Business Day, the second Business Day immediately succeeding such Interest Payment Date); or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts
exist at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity
Date in cash regardless of whether their Notes have been converted following such Regular Record Date. 
 (i) The Person in whose name the
certificate for any ADSs delivered upon conversion is registered shall be treated as a holder of record of such ADSs as of the close of business on the relevant Conversion Date. Upon a conversion of Notes, such Person shall no longer be a Holder of
such Notes surrendered for conversion. 
 (j) The Company shall not issue any Fractional ADS upon conversion of the Notes and shall instead
pay cash in lieu of any Fractional ADS deliverable upon conversion based on the Last Reported Sale Price of the ADSs on the relevant Conversion Date. 

(k) In accordance with the Deposit Agreement, the Company shall issue to the ADS Custodian such Ordinary Shares required for the issuance of
the ADSs upon conversion of the Notes, plus written delivery instructions (if requested by the ADS Depositary or the ADS Custodian) for such ADSs and any other information or documentation required by the ADS Depositary or the ADS Custodian in
connection with each issue of Ordinary Shares and issuance and delivery of ADSs. 
 Section 14.03. Increased Conversion Rate
Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) If a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole
Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional ADSs (the “Additional ADSs”), as described below. A
conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the
Make-Whole Fundamental Change up to, and including, the second Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the
proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). The Company shall provide written notification to Holders and the Trustee of the
Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

  
 60 

 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental
Change, the Company shall cause to be delivered ADSs, including the Additional ADSs, in accordance with Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause
(b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the
Conversion Obligation shall be calculated based solely on the ADS Price for the transaction and shall be deemed to be an amount of cash per US$1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for
Additional ADSs), multiplied by such ADS Price. 
 (c) The number of Additional ADSs, if any, by which the Conversion Rate shall be
increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “ADS Price”) paid (or
deemed to be paid) per ADS in the Make-Whole Fundamental Change. If the holders of the ADSs receive in exchange for their ADSs only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the ADS
Price shall be the cash amount paid per ADS. Otherwise, the ADS Price shall be the average of the Last Reported Sale Prices of the ADSs over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective
Date of the Make-Whole Fundamental Change. 
 (d) The ADS Prices set forth in the column headings of the table below shall be adjusted as of
any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted ADS Prices shall equal the ADS Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate immediately prior to such adjustment giving rise to the ADS Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional ADSs set forth in the table below shall be adjusted in the same manner and
at the same time as the Conversion Rate as set forth in Section 14.04. 

  
 61 

 (e) The following table sets forth the number of Additional ADSs to be received per US$1,000
principal amount of Notes pursuant to this Section 14.03 for each ADS Price and Effective Date set forth below:

 The exact ADS Prices and Effective Dates may not be set forth in the table above, in which case: 

(i) if the ADS Price is between two ADS Prices in the table above or the Effective Date is between two Effective Dates in the
table, the number of Additional ADSs shall be determined by a straight-line interpolation between the number of Additional ADSs set forth for the higher and lower ADS Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year; 
 (ii) if the ADS Price is greater than US$300.00 per ADS (subject to
adjustment in the same manner as the ADS Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional ADSs shall be added to the Conversion Rate; and 

(iii) if the ADS Price is less than US$45.34 per ADS (subject to adjustment in the same manner as the ADS Prices set forth in
the column headings of the table above pursuant to subsection (d) above), no Additional ADSs shall be added to the Conversion Rate. 
 Notwithstanding
the foregoing, in no event shall the Conversion Rate per US$1,000 principal amount of Notes exceed 22.0555 ADSs, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 

(f) Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04. 

(g) If the Holder elects to convert its Notes in connection with the Company’s election to redeem the Notes in respect of a Change in Tax
Law pursuant to Section 16.01, the Conversion Rate shall be increased by a number of additional ADSs determined pursuant to this Section 14.03(g). The Company shall settle conversions of Notes as described in Section 14.02 and, for
the avoidance of doubt, pay Additional Amounts, if any, with respect to any such conversion. 
 A conversion shall be deemed to be in
connection with the Company’s election to redeem the Notes in respect of a Change in Tax Law if such conversion occurs during the period from, and including, the date the Company provides the related notice of redemption to Holders until the
close of business on the Business Day immediately preceding the Redemption Date (or, if the Company fails to pay the Redemption Price, such later date on which the Company pays the Redemption Price). 

  
 62 

 Simultaneously with providing such notice of redemption, the Company shall publish a notice
containing this information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through such other public medium as the Company may use at that time. 

The number of additional ADSs by which the Conversion Rate will be increased in the event the Company elects to redeem the Notes in respect of
a Change in Tax Law will be determined by reference to the table in clause (e) above based on the Redemption Reference Date and the Redemption Reference Price (each as defined below), but determined for purposes of this Section 14.03(g) as
if (x) the Holder had elected to convert its Notes in connection with a Make-Whole Fundamental Change, (y) the applicable “Redemption Reference Date” were the “Effective Date” as specified in clause (c) above and
(z) the applicable “Redemption Reference Price” were the “ADS price” as specified in clause (c) above. For this purpose, the date on which the Company delivers notice of redemption is the “Redemption Reference
Date” and the average of the Last Reported Sale Prices of the ADSs over the five Trading Day period immediately preceding the date the Company delivers such notice of redemption is the “Redemption Reference Price.” 

Section 14.04. Adjustment of Conversion Rate. If the number of Ordinary Shares represented by the ADSs is changed, after the date
of this Indenture, for any reason other than one or more of the events described in this Section 14.04, the Company shall make an appropriate adjustment to the Conversion Rate such that the number of Ordinary Shares represented by the ADSs upon
which conversion of the Notes is based remains the same. 
 Notwithstanding the adjustment provisions described in this Section 14.04,
if the Company distributes to holders of the Ordinary Shares any cash, rights, options, warrants, shares of Capital Stock or similar equity interest, evidences of indebtedness or other assets or property of the Company (but excluding Expiring
Rights) and a corresponding distribution is not made to holders of the ADSs, but, instead, the ADSs shall represent, in addition to Ordinary Shares, such cash, rights, options, warrants, shares of Capital Stock or similar equity interest, evidences
of indebtedness or other assets or property of the Company, then an adjustment to the Conversion Rate described in this Section 14.04 shall not be made until and unless a corresponding distribution (if any) is made to holders of the ADSs, and
such adjustment to the Conversion Rate shall be based on the distribution made to the holders of the ADSs and not on the distribution made to the holders of the Ordinary Shares. However, in the event that the Company issues or distributes to all
holders of the Ordinary Shares any Expiring Rights, notwithstanding the immediately preceding sentence, the Company shall adjust the Conversion Rate pursuant to Section 14.04(b) (in the case of Expiring Rights entitling holders of the Ordinary
Shares for a period of not more than 45 calendar days after the announcement date of such issuance to subscribe for or purchase Ordinary Shares or ADSs) or Section 14.04(c) (in the case of all other Expiring Rights). 

For the avoidance of doubt, if any event described in this Section 14.04 results in a change to the number of Ordinary Shares represented
by the ADSs, then such a change shall be deemed to satisfy the Company’s obligation to effect the relevant adjustment to the Conversion Rate on account of such an event to the extent such change reflects what a corresponding change to the
Conversion Rate would have been on account of such event. 

  
 63 

 The Conversion Rate shall be adjusted from time to time by the Company if any of the
following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange
offer), at the same time and upon the same terms as holders of the ADSs and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes, as if they held a number of
ADSs equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. Neither the Trustee nor the Conversion Agent shall have any responsibility to monitor the accuracy of any calculation
of any adjustment to the Conversion Rate and the same shall be conclusive and binding on the Holders, absent manifest error. Notice of such adjustment to the Conversion Rate shall be given by the Company promptly to the Holders, the Trustee and the
Paying Agent and Conversion Agent and shall be conclusive and binding on the Holders, absent manifest error. 
 (a) If the Company
exclusively issues Ordinary Shares as a dividend or distribution on the Ordinary Shares, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	 the Conversion Rate in effect immediately prior to the close of business on the Record Date for the ADSs of such dividend or distribution, or
immediately prior to the open of business on the effective date of such share split or share combination,
 as applicable;

			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on such Record Date or immediately after the open of business on such effective date, as applicable;
			
	OS0	  	=	  	the number of Ordinary Shares outstanding immediately prior to the close of business on such Record Date or immediately prior to the open of business on such effective date, as applicable; and
			
	OS1	  	=	  	the number of Ordinary Shares outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 14.04(a) shall become effective immediately after the close of
business on the Record Date for the ADSs for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type
described in this Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 64 

 (b) If the Company issues to all or substantially all holders of the Ordinary Shares
(directly or in the form of ADSs) any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase Ordinary Shares (directly or in the form of
ADSs) at a price per Ordinary Share that is less than the average of the Last Reported Sale Prices of the Ordinary Shares or the ADSs, as the case may be (divided by, in the case of the ADSs, the number of Ordinary Shares then represented by
one ADS), for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for the ADSs for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on such Record Date;
			
	OS1	  	=	  	the number of Ordinary Shares outstanding immediately prior to the close of business on such Record Date;
			
	X	  	=	  	the total number of Ordinary Shares (directly or in the form of ADSs) deliverable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of Ordinary Shares equal to (i) the aggregate price payable to exercise such rights, options or warrants, divided by (ii) the quotient of (a) the average of the Last Reported Sale Prices of the ADSs over
the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants divided by (b) the number of Ordinary Shares then represented
by one ADS.

 Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants
are issued and shall become effective immediately after the close of business on the Record Date for the ADSs for such issuance. To the extent that Ordinary Shares or ADSs are not delivered after the expiration of such rights, options or warrants,
the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of Ordinary Shares
actually delivered (directly or in the form of ADSs). If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such the Record Date for the ADSs for such
issuance had not occurred. 

  
 65 

 For purposes of this Section 14.04(b), in determining whether any rights, options or
warrants entitle the holders to subscribe for or purchase Ordinary Shares (directly or in the form of ADSs) at a price per Ordinary Share that is less than such average of the Last Reported Sale Prices of the Ordinary Shares or the ADSs, as the case
may be (divided by, in the case of the ADSs, the number of Ordinary Shares then represented by one ADS), for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for
such issuance, and in determining the aggregate offering price of such Ordinary Shares or ADSs, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or
conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 (c) If the Company
distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Ordinary
Shares (directly or in the form of ADSs), excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in
cash as to which an adjustment was effected pursuant to Section 14.04(d), and (iii) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital Stock, evidences of
indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following
formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for the ADSs for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on such Record Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the ADSs (divided by the number of Ordinary Shares then represented by one ADS) over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding Ordinary Share (directly or in the form of ADSs) on the Record Date for the ADSs for such
distribution.

  
 66 

 Any increase made under the portion of this Section 14.04(c) above shall become effective immediately
after the close of business on the Record Date for the ADSs for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such distribution had not
been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each US$1,000
principal amount thereof, at the same time and upon the same terms as holders of the ADSs receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of ADSs equal to
the Conversion Rate in effect on the Record Date for the ADSs for the distribution. 
 With respect to an adjustment pursuant to this
Section 14.04(c) where there has been a payment of a dividend or other distribution on the Ordinary Shares (directly or in the form of ADSs) of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a
Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate
shall be increased based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Ordinary Shares (directly or in the form of ADSs) applicable to one Ordinary Share (determined by reference
to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to the ADSs were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the ADSs (divided by the number of Ordinary Shares then represented by one ADS) over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation
Period; provided that in respect of any conversion during the Valuation Period, references in the portion of this Section 14.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading
Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including, the Conversion Date in determining the Conversion Rate. 

  
 67 

 For purposes of this Section 14.04(c) (and subject in all respect to
Section 14.11), rights, options or warrants distributed by the Company to all holders of the Ordinary Shares (directly or in the form of ADSs) entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including
Ordinary Shares (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Ordinary Shares
(directly or in the form of ADSs); (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Ordinary Shares (directly or in the form of ADSs), shall be deemed not to have been distributed for purposes of this
Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been
distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to
the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any
and each such event shall be deemed to be the date of distribution and Record Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on
such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding
sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options or warrants
that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and
(y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per Ordinary Share redemption or purchase
price received by a holder or holders of Ordinary Shares (directly or in the form of ADSs) with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Ordinary Shares
(directly or in the form of ADSs) as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate
shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of Section 14.04(a),
Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of: 

(A) a dividend or distribution of Ordinary Shares (directly or in the form of ADSs) to which Section 14.04(a) is applicable (the
“Clause A Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which
Section 14.04(b) is applicable (the “Clause B Distribution”), 
 then (1) such dividend or distribution, other than the Clause A
Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this
Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment
required by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Record Date” of the Clause A Distribution and the Clause B Distribution shall be
deemed to be the Record Date of the Clause C Distribution and (II) any Ordinary Shares (directly or in the form of ADSs) included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately
prior to the close of business on such Record Date or immediately after the open of business on such effective date, as applicable” within the meaning of Section 14.04(a) or “outstanding immediately prior to the close of business on
such Record Date” within the meaning of Section 14.04(b). 

  
 68 

 (d) If any cash dividend or distribution is made to all or substantially all holders of the
Ordinary Shares (directly or in the form of ADSs), the Conversion Rate shall be adjusted based on the following formula: 
  

 
 Where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for the ADSs for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on such Record Date;
			
	SP0	  	=	  	the Last Reported Sale Price of the ADSs (divided by the number of Ordinary Shares then represented by one ADS) on the Trading Day immediately preceding the Ex-Dividend Date for such
dividend or distribution; and
			
	C	  	=	  	the amount in cash per Ordinary Share the Company distributes to all or substantially all holders of the Ordinary Shares (directly or in the form of ADSs).

 Any increase pursuant to this Section 14.04(d) shall become effective immediately after the close of business on the
Record Date for the ADSs for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or
distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined
above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each US$1,000 principal amount of Notes, at the same time and upon the same terms as holders of the ADSs, the amount of cash that such Holder would have received if
such Holder owned a number of ADSs equal to the Conversion Rate on the Record Date for the ADSs for such cash dividend or distribution. 

  
 69 

 (e) If the Company or any of its Subsidiaries or Consolidated Affiliated Entities makes a
payment in respect of a tender or exchange offer for the Ordinary Shares (directly or in the form of ADSs), to the extent that the cash and value of any other consideration included in the payment per Ordinary Share exceeds the average of the Last
Reported Sale Prices of the ADSs (divided by the number of Ordinary Shares then represented by one ADS) over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange
offer expires, the Conversion Rate shall be increased based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for Ordinary Shares or ADSs, as the case may be, purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of Ordinary Shares outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all Ordinary Shares or ADSs, as the case may be, accepted for purchase or
exchange in such tender or exchange offer);
			
	OS1	  	=	  	the number of Ordinary Shares outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all Ordinary Shares or ADSs, as the case may be, accepted for purchase or exchange in
such tender or exchange offer); and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the ADSs (divided by the number of Ordinary Shares then represented by one ADS) over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next
succeeding the date such tender or exchange offer expires.

 The adjustment to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th
Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days immediately following, and including, the
Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 14.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and
including, the Trading Day next succeeding the expiration date of such tender or exchange offer to, and including, the Conversion Date in determining the Conversion Rate. For the avoidance of doubt, no adjustment to the Conversion Rate under this
Section 14.04(e) shall be made if such adjustment would result in a decrease in the Conversion Rate. 

  
 70 

 (f) [RESERVED] 

(g) Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of Ordinary Shares or ADSs or any securities
convertible into or exchangeable for Ordinary Shares or ADSs or the right to purchase Ordinary Shares or ADSs or such convertible or exchangeable securities. 

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent
permitted by applicable law and subject to the applicable rules of The NASDAQ Global Select Market and any other securities exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the
Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest, and the Company may (but is not required to) increase the Conversion Rate
to avoid or diminish any income tax to holders of the Ordinary Shares or the ADSs or rights to purchase Ordinary Shares or ADSs in connection with a dividend or distribution of Ordinary Shares or ADSs (or rights to acquire Ordinary Shares or ADSs)
or similar event. 
 (i) Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted: 

(i) upon the issuance of any Ordinary Shares or ADSs pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on the Company’s securities and the investment of additional optional amounts in Ordinary Shares or ADSs under any plan; 

(ii) upon the issuance of any Ordinary Shares or ADSs or options or rights to purchase those Ordinary Shares or ADSs pursuant
to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries or Consolidated Affiliated Entities; 

(iii) upon the issuance of any Ordinary Shares or ADSs pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 

(iv) solely for a change in the par value of the Ordinary Shares or ADSs; or 

(v) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of an ADS. 
 (k) Whenever the Conversion Rate is adjusted as herein
provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry
that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the
date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect
the legality or validity of any such adjustment. 

  
 71 

 (l) For purposes of this Section 14.04, the number of Ordinary Shares at any time
outstanding shall not include Ordinary Shares held in the treasury of the Company (directly or in the form of ADSs) so long as the Company does not pay any dividend or make any distribution on Ordinary Shares held in the treasury of the Company
(directly or in the form of ADSs), but shall include Ordinary Shares issuable in respect of scrip certificates issued in lieu of fractions of Ordinary Shares. 

(m) For purposes of this Section 14.04, the “effective date” means the first date on which the ADSs trade on the applicable
exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable. 

Section 14.05. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported
Sale Prices, the ADS Price for purposes of a Make-Whole Fundamental Change or the Redemption Reference Price for purposes of a redemption of the Notes in connection with a Change in Tax Law over a span of multiple days, the Board of Directors shall
make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective pursuant to Section 14.04, or any event requiring an adjustment to the Conversion Rate pursuant to Section 14.04 where the
Record Date, effective date or expiration date, as the case may be, of the event occurs, at any time during the period when such Last Reported Sale Prices or ADS Prices are to be calculated. 

Section 14.06. Ordinary Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but
unissued Ordinary Shares or Ordinary Shares held in treasury, a sufficient number of Ordinary Shares that corresponds to the number of ADSs due upon conversion of the Notes from time to time as such Notes are presented for conversion (assuming that
at the time of computation of such number of Ordinary Shares, all such Notes would be converted by a single Holder). 

Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Ordinary Shares. 

(a) In the case of: 

(i) any recapitalization, reclassification or change of the Ordinary Shares (other than changes resulting from a subdivision or
combination), 
 (ii) any consolidation, merger, combination or similar transaction involving the Company, 

  
 72 

 (iii) any sale, lease or other transfer to a third party of the consolidated
assets of the Company and the Company’s Subsidiaries and Consolidated Affiliated Entities substantially as an entirety or 

(iv) any statutory share exchange, 

in each case, as a result of which the Ordinary Shares would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Merger Event”), then, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee
a supplemental indenture permitted under Section 10.01(f) providing that, at and after the effective time of such Merger Event, the right to convert each US$1,000 principal amount of Notes shall be changed into a right to convert such principal
amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of ADSs equal to the Conversion Rate immediately prior to such Merger
Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one ADS is entitled to receive)
upon such Merger Event; provided, however, that at and after the effective time of the Merger Event the number of ADSs otherwise deliverable upon conversion of the Notes in accordance with Section 14.02 shall instead be
deliverable in the amount and type of Reference Property that a holder of that number of ADSs would have been entitled to receive in such Merger Event. 

If the Merger Event causes the Ordinary Shares to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of holder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration actually
received by the holders of the ADSs and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one ADS. The Company shall provide
written notice to Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that
shall be as nearly equivalent as is practicable to the adjustments provided for in this Article 14 (it being understood that no such adjustments shall be required with respect to any portion of the Reference Property that does not consist of shares
of Common Equity (however evidenced) or depositary receipts in respect thereof). If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof)
of a Person other than the Company or the successor or purchasing Person, as the case may be, in such Merger Event, then such other Person shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional
provisions to protect the interests of the Holders of the Notes, including the right of Holders to require the Company to repurchase their Notes upon a Fundamental Change pursuant to Section 15.02 and the right of Holders to require the Company
to repurchase their Notes on the Repurchase Date pursuant to Section 15.01, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. 

  
 73 

 (b) [RESERVED] 

(c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 14.07. None of the
foregoing provisions shall affect the right of a holder of Notes to convert its Notes into ADSs as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Merger Event. 

(d) The above provisions of this Section shall similarly apply to successive Merger Events. 

Section 14.08. Certain Covenants. (a) The Company covenants that all ADSs delivered upon conversion of Notes, and all
Ordinary Shares represented by such ADSs, will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any ADSs to be provided for the purpose of conversion of Notes hereunder, or any Ordinary Shares
represented by such ADSs, require registration with or approval of any governmental authority under any federal or state law before such ADSs may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and
interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if at
any time the ADSs shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the ADSs shall be so listed on such exchange or automated quotation system, any ADSs deliverable
upon conversion of the Notes. 
 (d) The Company further covenants to take all actions and obtain all approvals and registrations required
with respect to the conversion of the Notes into ADSs and the issuance, and deposit into the ADS facility, of the Ordinary Shares represented by such ADSs. The Company also undertakes to maintain, as long as any Notes are outstanding, the
effectiveness of a registration statement on Form F-6 relating to the ADSs and an adequate number of ADSs available for issuance thereunder such that ADSs can be delivered in accordance with the terms of this
Indenture, the Notes and the Deposit Agreement upon conversion of the Notes. In addition, the Company further covenants to provide Holders with a reasonably detailed description of the mechanics for the delivery of ADSs upon conversion of Notes as
set forth in the Deposit Agreement upon request. 
 Section 14.09. Responsibility of Trustee. The Trustee and any other
Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the
Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and
any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any ADSs, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and
the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any ADSs or stock certificates or
other securities or property or cash upon the surrender of any Note for the purpose of conversion, the accuracy or inaccuracy of any mathematical calculation or formulae under this Indenture, whether by the Company or any Person so authorized by the
Company for such purpose under this Indenture or the failure by the Company to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the
Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount of ADSs or
securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of
Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to
file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 

  
 74 

 Section 14.10. Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 14.04 or
Section 14.11; 
 (b) Merger Event; or 

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its
Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall
cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable
date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Ordinary
Shares or ADSs, as the case may be, of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Ordinary Shares or ADSs, as the case may be, of record shall be entitled to exchange their Ordinary Shares
or ADSs, as the case may be, for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect
the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up. 

  
 75 

 Section 14.11. Stockholder Rights Plans. To the extent that the Company has a
rights plan in effect upon conversion of the Notes, each ADS delivered upon such conversion shall be entitled to receive (either directly or in respect of the Ordinary Shares underlying such ADSs) the appropriate number of rights, if any, and the
certificates representing the ADSs delivered upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to
any conversion, the rights have separated from the Ordinary Shares underlying the ADSs in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company
distributed to all or substantially all holders of the Ordinary Shares Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

Section 14.12. Termination of Depositary Receipt Program. If the Ordinary Shares cease to be represented by American Depositary
Shares issued under a depositary receipt program sponsored by the Company, all references in this Indenture to the ADSs shall be deemed to have been replaced by a reference to the number of Ordinary Shares (and other property, if any) represented by
the ADSs on the last day on which the ADSs represented the Ordinary Shares and as if the Ordinary Shares and the other property had been distributed to holders of the ADSs on that day. In addition, all references to the Last Reported Sale Price of
the ADSs will be deemed to refer to the Last Reported Sale Price of the Ordinary Shares, and other appropriate adjustments, including adjustments to the Conversion Rate, will be made to reflect such change. In making such adjustments, where currency
translations between U.S. dollars and any other currency are required, the exchange rate in effect on the date of determination will apply. 

ARTICLE 15 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 15.01. Repurchase at Option of Holders. 

(a) Each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash on July 1, 2023 (the
“Repurchase Date”), all of such Holder’s Notes, or any portion thereof that is an integral multiple of US$1,000 principal amount, at a repurchase price (the “Repurchase Price”) that is equal to 100% of the
principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the Repurchase Date; provided that any such accrued and unpaid interest shall be paid not to the Holders submitting the Notes for
repurchase on the Repurchase Date but instead to the Holders of such Notes at the close of business on the Regular Record Date immediately preceding the Repurchase Date. Not later than 20 Business Days prior to the Repurchase Date, the Company shall
mail a notice (the “Company Notice”) by first class mail to the Trustee, to the Paying Agent and to each Holder at its address shown in the Note Register of the Note Registrar (and to beneficial owners as required by applicable
law). The Company Notice shall include a form of Repurchase Notice to be completed by a holder and shall state: 
 (i) the
last date on which a Holder may exercise its repurchase right pursuant to this Section 15.01 (the “Repurchase Expiration Time”); 

(ii) the Repurchase Price; 

(iii) the Repurchase Date; 

  
 76 

 (iv) the name and address of the Conversion Agent and Paying Agent; 

(v) that the Notes with respect to which a Repurchase Notice has been delivered by a Holder may be converted only if the Holder
withdraws the Repurchase Notice in accordance with the terms of this Indenture; 
 (vi) that the Holder shall have the right
to withdraw any Notes surrendered prior to the Repurchase Expiration Time; and 
 (vii) the procedures a Holder must follow
to exercise its repurchase rights under this Section 15.01 and a brief description of those rights. 
 At the Company’s request, the Trustee shall
give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 

Simultaneously with providing the Company Notice, the Company shall publish a notice containing the information included in the Company Notice
in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.01. 
 Repurchases of Notes under this
Section 15.01 shall be made, at the option of the Holder thereof, upon: 
 (A) delivery to the Trustee by the Holder of
a duly completed notice (the “Repurchase Notice”) in the form set forth in Attachment 3 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for
surrendering interests in global notes, if the Notes are Global Notes, in each case during the period beginning at any time from the open of business on the date that is 20 Business Days prior to the Repurchase Date until the close of business on
the second Business Day immediately preceding the Repurchase Date; and 
 (B) delivery of the Notes, if the Notes are
Physical Notes, to the Trustee at any time after delivery of the Repurchase Notice (together with all necessary endorsements) at the Corporate Trust Office of the Trustee, or book-entry transfer of the Notes, if the Notes are Global Notes, in
compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Repurchase Price therefor. 

Each Repurchase Notice shall state: 

(A) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 

  
 77 

 (B) the portion of the principal amount of the Notes to be repurchased,
which must be US$1,000 or an integral multiple thereof; and 
 (C) that the Notes are to be repurchased by the Company
pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder
delivering to the Trustee the Repurchase Notice contemplated by this Section 15.01 shall have the right to withdraw, in whole or in part, such Repurchase Notice at any time prior to the close of business on the second Business Day immediately
preceding the Repurchase Date by delivery of a duly completed written notice of withdrawal to the Trustee in accordance with Section 15.03. 

The Trustee shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. 

No Repurchase Notice with respect to any Notes may be delivered and no Note may be surrendered for repurchase pursuant to this
Section 15.01 by a Holder thereof to the extent such Holder has also delivered a Fundamental Change Repurchase Notice with respect to such Note in accordance with Section 15.02 and not validly withdrawn such Fundamental Change Repurchase
Notice in accordance with Section 15.03. 
 (b) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option
of the Holders on the Repurchase Date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such Repurchase Date (except in the case of an acceleration resulting from a default by the
Company in the payment of the Repurchase Price with respect to such Notes). The Trustee will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration
resulting from a default by the Company in the payment of the Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been
cancelled, and, upon such return or cancellation, as the case may be, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time,
each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to US$1,000 or an integral multiple of US$1,000, on the Business Day
(the “Fundamental Change Repurchase Date”) notified in writing by the Company as set forth in Section 15.02(c) that is not less than 20 Business Days or more than 35 Business Days following the date of the Fundamental Change
Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase
Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of
accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. 

  
 78 

 (b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the
Holder thereof, upon: 
 (i) delivery to the Trustee by a Holder of a duly completed notice (the “Fundamental Change
Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in global notes,
if the Notes are Global Notes, in each case on or before the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Trustee at any time after delivery of the Fundamental
Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case
such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 
 The Fundamental Change
Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (i) in the case of Physical Notes, the
certificate numbers of the Notes to be delivered for repurchase; 
 (ii) the portion of the principal amount of Notes to be
repurchased, which must be US$1,000 or an integral multiple thereof; and 
 (iii) that the Notes are to be repurchased by the
Company pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Trustee the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of
business on the second Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Trustee in accordance with Section 15.03. 

The Trustee shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal
thereof. 
 No Fundamental Change Repurchase Notice with respect to any Notes may be delivered and no Note may be surrendered by a Holder
for repurchase thereof if such Holder has also surrendered a Repurchase Notice in accordance with Section 15.01 and not validly withdrawn such Repurchase Notice in accordance with Section 15.03. 

  
 79 

 (c) On or before the 20th calendar day after the occurrence of the effective date of a
Fundamental Change, the Company shall provide to all Holders and the Trustee a written notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at
the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the
Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such
information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

(vi) the name and address of the Trustee; 

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate; 

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and 

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02. 
 At the Company’s request, the
Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

  
 80 

 (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at
the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a default by
the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Trustee will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the
case of an acceleration resulting from a default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the
Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 15.03. Withdrawal of Repurchase Notice or Fundamental Change Repurchase Notice. (a) A Repurchase Notice or
Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a duly completed written notice of withdrawal delivered to the Corporate Trust Office in accordance with this Section 15.03 at any time prior to the close
of business on the second Business Day immediately preceding the Repurchase Date or prior to the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date, as the case may be, specifying: 

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is
being submitted, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original Repurchase
Notice or Fundamental Change Repurchase Notice, as the case may be, which portion must be in principal amounts of US$1,000 or an integral multiple of US$1,000; 

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 

Section 15.04. Deposit of Repurchase Price or Fundamental Change Repurchase Price. (a) The Company will deposit with the
Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or prior to 10:00 a.m., New York City time, on the Repurchase
Date or Fundamental Change Repurchase Date, as the case may be, an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Repurchase Price or Fundamental Change Repurchase Price. Subject to receipt of funds
and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn in accordance with Section 15.03) will be made on the later of (i) the Repurchase Date or
Fundamental Change Repurchase Date, as the case may be, (provided the Holder has satisfied the conditions in Section 15.01 or Section 15.02, as the case may be) and (ii) the time of book-entry transfer or the delivery of such
Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 15.01 or Section 15.02, as applicable, by mailing checks for the amount payable to the Holders of such Notes
entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee
shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be. 

  
 81 

 (b) If by 10:00 a.m., New York City time, on the Repurchase Date or Fundamental Change
Repurchase Date, as the case may be, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Repurchase Date or Fundamental Change
Repurchase Date, as the case may be, then, with respect to the Notes that have been properly surrendered for repurchase and not validly withdrawn, on such Repurchase Date or Fundamental Change Repurchase Date, as the case may be, (i) such Notes
will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of
the Holders of such Notes will terminate (other than the right to receive the Repurchase Price or Fundamental Change Repurchase Price, as the case may be). 

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.01 or Section 15.02, the Company shall execute
and instruct the Trustee who shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the
Company will, if required: 
 (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 
 (b) file a Schedule TO or other required
schedule under the Exchange Act; and 
 (c) otherwise comply with all federal and state securities laws in connection with any offer by the
Company to repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the
manner specified in this Article 15. 
 ARTICLE 16 

OPTIONAL REDEMPTION 

Section 16.01. Optional Redemption for Changes in the Tax Law of the Relevant Taxing Jurisdiction. Other than as described in this
Article 16, the Notes may not be redeemed by the Company at its option prior to maturity. If the Company has, or on the next Interest Payment Date would, become obligated to pay to the Holder of any Note Additional Amounts that are more than a de
minimis amount, as a result of: 
 (a) any change or amendment on or after June 26, 2018 (or, in the case of a jurisdiction that
becomes a Relevant Taxing Jurisdiction after such date, after such later date) in the laws or any rules or regulations of a Relevant Taxing Jurisdiction; or 

  
 82 

 (b) any change on or after June 26, 2018 (or, in the case of a jurisdiction that
becomes a Relevant Taxing Jurisdiction after such date, after such later date) in an interpretation, administration or application of such laws, rules or regulations by any legislative body, court, governmental agency, taxing authority or regulatory
or administrative authority of such Relevant Taxing Jurisdiction (including the enactment of any legislation and the announcement or publication of any judicial decision or regulatory or administrative interpretation or determination); 

(each, a “Change in Tax Law”), the Company may, at its option, redeem all but not part of the Notes (except in respect of certain Holders
that elect otherwise as described below) at a “Redemption Price” equal to 100% of the principal amount plus accrued and unpaid interest, if any, to, but not including the date on which the Notes are redeemed (the “Redemption
Date”), including, for the avoidance of doubt, any Additional Amounts with respect to such Redemption Price; provided that the Company may only redeem the Notes if: (i) the Company cannot avoid such obligations by taking
commercially reasonable measures available to the Company (provided that changing the jurisdiction of incorporation of the Company shall be deemed not to be a commercially reasonable measure); and (ii) the Company delivers to the Trustee
an opinion of outside legal counsel of recognized standing in the Relevant Taxing Jurisdiction and an Officers’ Certificate attesting to such Change in Tax Law and obligation to pay Additional Amounts. 

Notwithstanding anything to the contrary in this Article 16, neither the Company nor any successor Person may redeem any of the Notes in the
case that Additional Amounts are payable in respect of PRC withholding tax at the Applicable PRC Rate or less solely as a result of the Company or its successor Person being considered a PRC tax resident under the PRC Enterprise Income Tax law. 

If the Redemption Date occurs after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company shall pay
the full amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the record holder of the Notes on the Regular Record Date corresponding to such Interest Payment Date, and the Redemption Price payable to the Holder who
presents a Note for redemption shall be equal to 100% of the principal amount of such Note, including, for the avoidance of doubt, any Additional Amounts with respect to such Redemption Price. 

The Company shall give Holders of Notes not less than 30 days’ but no more than 60 days’ notice prior to the Redemption Date.
Simultaneously with providing such notice, the Company shall publish a notice containing this information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through such other
public medium as the Company may use at that time. The Redemption Date must be a Business Day. 

  
 83 

 Upon receiving such notice of redemption, each Holder shall have the right to elect to not
have its Notes redeemed, in which case the Company shall not be obligated to pay any Additional Amounts on any payment with respect to such Notes solely as a result of such Change in Tax Law that resulted in the obligation to pay such Additional
Amounts (whether upon conversion, required repurchase in connection with a Fundamental Change or the Repurchase Date, maturity or otherwise, and whether in ADSs, Reference Property or otherwise) after the Redemption Date (or, if the Company fails to
pay the Redemption Price on the Redemption Date, such later date on which the Company pays the Redemption Price), and all future payments with respect to such Notes shall be subject to the deduction or withholding of such Relevant Taxing
Jurisdiction and taxes required by law to be deducted or withheld as a result of such Change in Tax Law; provided that, notwithstanding the foregoing, if a Holder electing not to have its Notes redeemed converts its Notes in connection with
the Company’s election to redeem the Notes in respect of such Change in Tax Law pursuant to Section 14.03(g) the Company shall be obligated to pay Additional Amounts, if any, with respect to such conversion. 

A Holder electing to not have its Notes redeemed must deliver to the Paying Agent a written notice of election so as to be received by the
Paying Agent prior to the close of business on the second Business Day immediately preceding the Redemption Date; provided that, a Holder that complies with the requirements for conversion in Section 14.02(b) shall be deemed to have
delivered a notice of its election to not have its Notes so redeemed. A Holder may withdraw any notice of election (other than such a deemed notice of election in connection with a conversion) by delivering to the Paying Agent a written notice of
withdrawal prior to the close of business on the Business Day immediately preceding the Redemption Date (or, if the Company fail to pay the Redemption Price on the Redemption Date, such later date on which the Company pays the Redemption Price). If
no election is made or deemed to have been made, the Holder shall have its Notes redeemed without any further action. 
 No Notes may be
redeemed if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date.

force and effect as if taken on such date, and no interest shall accrue in respect of the delay.

 [FORM OF REVERSE OF NOTE] 

MOMO INC. 
 1.25% Convertible
Senior Note due 2025 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.25% Convertible Senior
Notes due 2025 (the “Notes”), limited to the aggregate principal amount of US$650,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Initial Purchasers pursuant to the
exercise of their option to purchase additional Notes as set forth in the Purchase Agreement), subject to Section 2.10 of the Indenture, all issued or to be issued under and pursuant to an Indenture dated as of July 2, 2018 (the
“Indenture”), between the Company and The Bank of New York Mellon, as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties, privileges, disclaimers from liability and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject
to certain conditions specified in the Indenture. The Rule 144A Notes and the Regulation S Notes initially have separate CUSIP numbers and will initially not be fungible. 

In the case certain Events of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on,
all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions and certain exceptions set forth in the Indenture. In the case certain Events of Default relating to a bankruptcy (or similar proceeding) with respect to the Company or a Significant Subsidiary of the Company shall have occurred, the
principal of, and interest on, all Notes shall automatically become immediately due and payable, as set forth in the Indenture. 
 Subject
to the terms and conditions of the Indenture, the Company will make all payments in respect of the principal amount on the Maturity Date, the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, as the case may be, to
the Holder who surrenders a Note to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

Subject to the terms and conditions of the Indenture, Additional Amounts will be paid in connection with any payments made and deliveries
caused to be made by the Company or any successor to the Company under or with respect to the Indenture and the Notes, including, but not limited to, payments of principal (including, if applicable, the Redemption Price, the Repurchase Price and the
Fundamental Change Repurchase Price), payments of interest and deliveries of ADSs (together with payments for any Fractional ADS) upon conversion of the Notes to ensure that the net amount received by the beneficial owner after any applicable
withholding or deduction (and after deducting any taxes on the Additional Amounts) will equal the amount that would have been received by such beneficial owner had no such withholding or deduction been required. 

  
 A-7 

 The Indenture contains provisions permitting the Company and the Trustee in certain
circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the
Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay or cause to be delivered, as the case may be, the principal (including the Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest
on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed. 

The Notes are issuable in registered form without interest coupons in denominations of US$1,000 principal amount and integral multiples
thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized
denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder
of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Company may not redeem the Notes prior to the Maturity Date, except in the event of certain Changes in Tax Law as described in
Section 16.01 of the Indenture. No sinking fund is provided for the Notes. 
 The Holder has the right, at such Holder’s option,
to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of US$1,000 or integral multiples thereof) on the Repurchase Date at a price equal to the Repurchase Price. 

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for
cash all of such Holder’s Notes or any portion thereof (in principal amounts of US$1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, prior to the close of business on the second
Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is US$1,000 principal amount of Notes or an integral multiple thereof, into ADSs at the Conversion Rate specified in the Indenture, as adjusted from
time to time as provided in the Indenture. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined.
