for the most recent fiscal quarter (including after giving effect to any corporate restructuring or reorganization plan of the Company Group) or (y) that such Change in Law would not materially adversely affect the Company’s ability to make principal and Special Interest payments, if any, on the Notes when due or to effect the conversion of the Notes in accordance with this Indenture;

provided, however, that a transaction or event described in clause (b) above shall not constitute a Fundamental Change, if at least 90% of the consideration received or to be received by holders of the ADSs, excluding cash payments for Fractional ADSs and cash payments in respect of dissenters’ appraisal rights, in connection with such transaction or event consists of shares of Common Equity or ADSs in respect of Common Equity that are listed or quoted on any of The New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq Global Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or event that would otherwise constitute a Fundamental Change under clause (b) of the definition thereof and as a result of such transaction or event, the Notes become convertible into such consideration, excluding cash payments for Fractional ADSs; and provided further that an event that is not considered a Fundamental Change pursuant to this proviso shall not be a Fundamental Change solely because such event could also be subject to clause (a) above.

“Fundamental Change Company Notice” shall have the meaning specified in Section 15.02(c).

“Fundamental Change Repurchase Date” shall have the meaning specified in Section 15.02(a).

“Holder,” as applied to any Note, or other similar terms (but excluding the term “beneficial holder”), means any Person in whose name at the time a particular Note is registered on the Note Register.

specified in an Officer’s Certificate delivered to the Trustee before the original issuance of such Notes.

“Last Reported Sale Price” of the ADSs (or such other security for which a closing price must be determined) on any date means the closing sale price per ADS (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on that date as reported in composite transactions for the principal U.S. national or regional securities exchange on which the ADSs (or such other security) are traded. If the ADSs (or such other security) are not listed for trading on a U.S. national or regional securities exchange on the relevant date, the “Last Reported Sale Price” shall be the last quoted bid price for the ADSs in the over-the-counter market on the relevant date as reported by OTC Markets Group Inc. or a similar organization, and, if the ADSs (or such other security) are not so quoted, the “Last Reported Sale Price” shall be the average of the mid-point of the last bid and ask prices for the ADSs (or such other security) on the relevant date from each of at least three nationally recognized independent investment banking firms selected by the Company for this purpose. For the avoidance of doubt, if a Fundamental Change described in clause (d) of the definition thereof has occurred and the Newly Listed Equity has been accepted for listing on a Permitted Exchange, the “Last Reported Sale Price” will be determined based on the closing sale price of the Company’s Newly Listed Equity on the principal Permitted Exchange, with such changes to the foregoing definition (including the deletion of the immediately preceding sentence in this paragraph) as the Company’s Board of Directors determines in good faith are necessary to reflect the replacement of ADS (or other security) with Newly Listed Equity as set forth in a supplemental indenture to be executed by the Company and Trustee as described under Section

No service charge shall be imposed by the Company, the Trustee, 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 all ADSs deliverable upon conversion.

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.

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.

The Trustee and the Agents shall have no responsibility or obligation to any direct or indirect participant or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any direct or indirect participant or other Person (other than the Depositary and any other registered Holder of Notes) of any notice (including any notice of redemption pursuant to Article 16) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary procedures of the Depositary.

The Trustee and the Agents shall be entitled to conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its direct or indirect participants.

The Trustee and the Agents shall not have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among the members of, or participant in, the Depositary or among the beneficial owners in any Global Note(s)) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(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.

(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 Transfer Agent):

THIS SECURITY, THE AMERICAN DEPOSITARY SHARES DELIVERABLE UPON CONVERSION OF THIS SECURITY, IF ANY, AND THE CLASS A 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 “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A 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, AND HAS NOT BEEN FOR THE IMMEDIATELY PRECEDING THREE MONTHS, AN AFFILIATE OF 21VIANET GROUP, INC. (THE “COMPANY”), AND

(2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY, THE AMERICAN DEPOSITARY SHARES DELIVERABLE UPON CONVERSION OF THIS SECURITY, IF ANY, AND THE CLASS A ORDINARY SHARES REPRESENTED THEREBY, OR ANY BENEFICIAL INTEREST HEREIN OR THEREIN 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

(D) 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)(D) ABOVE, THE COMPANY, THE ADS DEPOSITARY AND THE TRANSFER AGENT FOR THE NOTES 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.

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, THE AMERICAN DEPOSITARY SHARES DELIVERABLE UPON CONVERSION HEREOF, IF ANY, AND THE CLASS A ORDINARY SHARES REPRESENTED THEREBY, OR A BENEFICIAL INTEREST HEREIN OR THEREIN.

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 (i) which such restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, 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 and the Agents 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 Paying Agent 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 and the Agents 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. In addition, the Company may effect the removal of the restrictive legend specified in this Section 2.05(c) upon the Company’s delivery to the Trustee of written notice to such effect, whereupon the restrictive legend set forth above and affixed on any Note shall be deemed, in accordance with the terms of the certificate representing such Note, to be removed therefrom without further action by the Company, the Trustee, the Holder(s) thereof or any other Person; at such time, such Note shall be deemed to be assigned an unrestricted CUSIP number as provided in the certificate representing such Note, it being understood that (i) the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such Depositary and (ii) if such Note is a Global Note and the Depositary thereof requires a mandatory exchange (or other process) to cause such Global Note to be identified by “unrestricted” CUSIP in the facilities of such Depositary, then for purposes of Section 4.06(e) hereof, such Global Note will not be deemed to be identified by an “unrestricted” CUSIP number until such time as such mandatory exchange (or other process) is effected.

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 Transfer Agent 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 Citibank, N.A. as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

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, subject to the Depositary’s applicable procedures, 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 Officer’s 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.

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, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Note Registrar in writing. 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, the Agents, any agent of the Company or any agent of the Trustee or the Agents shall be liable to any beneficial owner of a Global Note, a member of, or a participant in, the Depositary or any other Person for any aspect of the records relating to or payments or delivery of any securities or property to be made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for the delivery to any beneficial owner of a Global Note, a member of, or a participant in, the Depositary or any other Person (other than the Depositary) of any notice (including any Fundamental Change Repurchase Notice or notice of redemption).

None of the Company, the Trustee, the Agents or any agent of the Company or the Trustee or the Agents shall have responsibility or liability for any act or omission of the Depositary. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered Holder(s) (which shall be the Depositary or its nominee in the case of a Global Note).

(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 CLASS A 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:

(2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY AND THE ORDINARY SHARES REPRESENTED THEREBY, OR ANY BENEFICIAL INTEREST HEREIN OR THEREIN 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

(D) 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)(D) ABOVE, THE COMPANY, THE ADS 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.

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 THE AMERICAN DEPOSITARY SHARES EVIDENCED HEREBY OR A BENEFICIAL INTEREST HEREIN OR THEREIN.

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 ADS Depositary, 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 (or a Holder that was the Company’s Affiliate at any time during three months preceding the resale) 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 Paying Agent for cancellation in accordance with Section 2.08.

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, pre-funding 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 a Company Order and of such security, pre-funding and/or indemnity as the Trustee and the Company may require. No service charge shall be imposed by the Company, the Transfer Agent, the ADS Depositary, 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 repurchase (and not withdrawn) in accordance with Article 15 or has been selected for redemption in accordance with Article 16 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 pre-funding 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.

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 upon receipt of a Company Order 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 the Company or any of the Company’s agents, Subsidiaries, Consolidated Affiliated Entities or Affiliates, in each case that the Company controls, to be delivered and surrendered to the Paying Agent for cancellation. All Notes delivered to the Paying Agent shall be canceled promptly by it, and except for Notes surrendered for transfer or exchange, no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Paying Agent 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 prior written request in a Company Order.

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 and the Agents shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that the Trustee and the Agents shall have no liability for any defect in the “CUSIP” numbers as they appear on any Note, notice or elsewhere, and provided further 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 and the Agents in writing of any change in the “CUSIP” or “ISIN” numbers, as applicable.

Section 2.10 Additional Notes; Repurchases. The Company may, without the consent of, or notice to, 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 Special Interest accrued, if any, and, if applicable, restrictions on transfer in respect of such additional Notes) 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, ISIN or other identifying number from the Notes initially issued hereunder. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s 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, without the consent of the Holders, 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, Consolidated Affiliated Entities 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 Paying Agent for cancellation in accordance with Section 2.08 and upon receipt of a Company Order, the Paying Agent shall cancel all Notes so surrendered and such

Notes shall no longer be considered outstanding under this Indenture upon their repurchase. 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.

Section 2.11 Appointment of Authenticating Agent. As long as any Notes remain outstanding, the Company may, by an instrument in writing, appoint an authenticating agent (an “Authenticating Agent”), which shall be authorized to act on behalf of the Trustee to authenticate Notes pursuant to this Indenture. Notes authenticated by such Authenticating Agent shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee. Whenever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or to the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Such Authenticating Agent shall at all times be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and that has a combined capital and surplus of at least US$50,000,000.

ARTICLE 3

SATISFACTION AND DISCHARGE

Section 3.01 Satisfaction and Discharge. This Indenture shall upon request of the Company be discharged and shall 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, paid or converted 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 Paying Agent for cancellation; or (ii) the Company has deposited with the Trustee (or solely in the case of conversion, deposited ADSs with the ADS Depositary) and/or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Tax Redemption Date, any Optional Redemption Date, the Repurchase Date, any Fundamental Change Repurchase Date, upon conversion or otherwise cash and/or (solely in the case of conversion, if applicable) ADSs, sufficient to pay all of (or satisfy such Conversion Obligation in respect of) the outstanding Notes and has paid all other sums payable by the Company under this Indenture; (b) if the Company has deposited cash with the Trustee (or its agents), the Trustee has received irrevocable instruction from the Company to make a payment on (or to satisfy such Conversion Obligation in respect of) the outstanding Notes, as the case may be, after the Notes have become due and payable, whether on the Maturity Date, any Tax Redemption Date, any Optional Redemption Date, the Repurchase Date, any Fundamental Change Repurchase Date, upon conversion or otherwise; and (c) the Company has delivered to the Trustee an Officer’s 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 and the Agents under Section 7.06 shall survive.

ARTICLE 4

PARTICULAR COVENANTS OF THE COMPANY

Section 4.01 Payment of Principal and Special 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 Special Interest, if any, 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 initially will be the Paying Agent Office) 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 Paying Agent Office, provided, however, that the legal service of process against the Company shall in no circumstance be made at an office or agency of the Trustee.

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 Citibank, N.A. as the Paying Agent, Note Registrar, Transfer Agent and Conversion Agent and the office or agency of Citibank, N.A., located at 14^th Floor, 388 Greenwich Street, New York, New York 10013, United States of America, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

In acting hereunder and in connection with the Notes, the Paying Agent, Transfer Agent, Conversion Agent, Custodian, and Note Registrar shall act solely as an agent of the Company and will not assume any fiduciary duty or relationship of agency or trust for or with any of the beneficial owners or Holder(s).

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.

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:

Upon an Event of Default under Section 6.01(i) or Section 6.01(j) hereof, the Trustee (or, if Citicorp International Limited is the Trustee, Citibank, N.A.) shall automatically become the Paying Agent.

(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.

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, if any, 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, if any, 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 (excluding any such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the Commission) (giving effect to any applicable grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be provided to the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system (or any successor thereto), it being understood that the Trustee shall not be responsible for determining whether such filings have been made and when the Company’s statements, reports or documents are publically available and/or accessible electronically.

(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 Officer’s 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 (i) giving effect to all applicable grace periods thereunder and (ii) other than reports on Form 6-K to the extent such reports are not required to satisfy the “current public information” requirement of Rule 144), or the Notes are not otherwise freely tradable pursuant to Rule 144 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 or cause the Paying Agent (on behalf of the Company and subject to receipt of funds from the Company pursuant to the last paragraph in Section 4.04(a)) to pay Special Interest on the Notes. Such Special 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 described in this Section 4.06(d), by Holders other than Affiliates of the Company (or Holders that were Affiliates of the Company at any time during the three months immediately preceding). 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. Solely for purposes of this paragraph, the phrase “restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes” shall not include, for the avoidance of doubt, the assignment of a restricted CUSIP number or the existence of a restrictive notes legend on Notes in compliance with this Indenture, in either case, during the six-month period described in Section 4.06(d).

(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 number 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 380th day after the Last Date of Original Issuance of the Notes, the Company shall pay or cause the Paying Agent to pay Special 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 number 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) Special Interest will be payable in arrears on each Special Interest Payment Date as set forth in Section 2.03(b).

(g) Subject to the immediately preceding sentence, the Special 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 Special Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. Notwithstanding the foregoing, in no event shall any Special Interest that may accrue pursuant to Section 4.06(d) and Section 4.06(e) together with any Special Interest that may accrue in the event that the Company elects to pay Special Interest in respect of an Event of Default relating to its failure to comply with its obligations as set forth under Section 6.03, accrue at an aggregate rate in excess of 0.50% per annum, in each case, as a result of the Company’s failure 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, regardless of the number of such events or such circumstances giving rise to the requirement to pay such Special Interest. Such Special Interest will be the exclusive remedy available to Holders of the Notes for a failure of the Notes to become freely tradable pursuant to Rule 144 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.

(h) If Special Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to the Trustee and the Paying Agent an Officer’s Certificate to that effect stating (i) the amount of such Special Interest that is payable and (ii) the date on which such Special Interest is payable. Unless and until a Responsible Officer of the

Trustee receives at the Corporate Trust Office such a certificate, the Trustee and the Paying Agent may assume without inquiry that no such Special Interest is payable. If the Company has paid such Special Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment.

(i) for or on account of:

(A) any applicable taxes that would not have been imposed but for:

(3) the failure of the Holder or beneficial owner to comply with a timely written request from the Company or any successor of the Company, addressed to the Holder, to the extent such Holder or beneficial owner is legally entitled, without material undue burden, 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 to such Holder or beneficial owner;

(B) any estate, inheritance, gift, sale, transfer, personal property or similar applicable tax or excise taxes imposed on a transfer of the Notes;

(C) any applicable tax that is payable otherwise than by withholding, deduction or any other collection at source from payments or deliveries under or with respect to the Notes;

(E) any combination of applicable taxes 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), premium, if any, or any Special Interest, on, such Note or the payment of cash and/or 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 or delivery to the extent that such payment or delivery 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.

(b) In addition to the foregoing, the Company or its successor shall also pay and indemnify each Holder and beneficial owner for any present or future stamp, issue, registration, value added, court or documentary taxes, or any other excise or property taxes, charges or similar levies or taxes (including penalties, interest and any other reasonable expenses related thereto) which are levied by any Relevant Jurisdiction (and in the case of enforcement, any jurisdiction) on or in connection with the execution, delivery, registration or enforcement of any of the Notes, this Indenture or any other document or instrument referred to herein or the receipt of payments with respect thereto (including the receipt of ADSs (together with payment of cash for any Fractional ADS) or other consideration due upon conversion).

(c) If the Company becomes obligated to pay Additional Amounts with respect to any payment or delivery under or with respect to the Notes, the Company shall deliver to the Trustee and the Paying Agent, if other than the Trustee, on a date that is at least 30 days prior to the date of that payment or delivery (unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment or delivery date, in which case the Company shall notify the Trustee and the Paying Agent promptly thereafter) an Officer’s Certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The Officer’s Certificate must also set forth any other information reasonably necessary to enable the Paying Agent or the Trustee (on behalf of the Company and subject to receipt of funds from the Company pursuant to the last paragraph in Section 4.04(a)), as the case may be, to pay Additional Amounts to Holders on the relevant payment or delivery date. The Trustee, the Paying Agent and the Conversion Agent shall be entitled to conclusively rely on and accept such Officer’s Certificate as conclusive proof that such payments are necessary. The Company or its successor shall provide the Trustee, the Paying Agent and the Conversion Agent with documentation reasonably satisfactory to the Trustee, the Paying Agent and the Conversion Agent (as applicable) evidencing the payment of Additional Amounts.

(d) The Company shall make all withholdings and deductions required by law and shall remit the full amount deducted or withheld to the relevant tax authority in accordance with applicable law. Upon request, the Company shall provide to the Trustee a certified copy of an official receipt or, if official receipts are not obtainable, other documents reasonably satisfactory to the Trustee evidencing the payment of any applicable taxes so deducted or withheld. The Company will attach to each certified copy or other document a certificate stating the amount of such applicable taxes paid per US$1,000 principal amount of the Notes then outstanding. Copies of those receipts or other documentation, as the case may be, shall be made available by the Paying Agent to the Holders of the Notes upon prior written request.

(e) Any reference in this Indenture or the Notes in any context to the payment of cash and/or the delivery of ADSs (together with payment of cash for any Fractional ADS) or other consideration upon conversion of any Note or the payment of principal of (including the Redemption Price, the Repurchase Price and Fundamental Change Repurchase Price, if applicable) and any premium or Special Interest, (including any Special 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.

(f) The foregoing obligations shall survive termination, defeasance or discharge of this Indenture or any transfer by a Holder or beneficial owner of its Notes and will apply mutatis mutandis to any jurisdiction in which any successor to the Company is then, for tax purposes, incorporated, organized or resident or doing business (or any political subdivision or taxing authority thereof or therein) or any jurisdiction from or through which payment or delivery under or with respect to the Notes is made or deemed made by or on behalf of such successor (or any political subdivision or taxing authority thereof or therein).

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 Special Interest, if any, 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.

Delivery of such reports and documents 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.

In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the occurrence of any Event of Default or Default if such Event of Default or Default is then continuing, a written notice setting forth the details of any events that would constitute an Event of Default or Default, their status and the action that the Company is taking or proposing to take in respect thereof; provided that the Company is not required to deliver such notice if such Event of Default or Default has been cured. 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 a written notice

regarding such an occurrence, or (ii) the Trustee has received written notice at the Corporate Trust Office 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.

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 Special Interest, if any, 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 Special 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 Special 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 180^th day immediately following, and including, the date on which such Event of Default first occurred; and

(b) if such Event of Default has not been cured or validly waived prior to the 181^st 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 181^st 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 360^th day immediately following, and including, the date on which such Event of Default first occurred.

Special Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Special Interest payable pursuant to Section 4.06(d) or Section 4.06(e). In no event shall Special Interest accrue on the Notes on any day under this Indenture (taking any Special Interest payable pursuant to this Section 6.03 together with any Special Interest payable pursuant to Section 4.06(d) and Section 4.06(e)) at an annual rate accruing in excess of 0.50% per annum, 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 Special Interest shall be payable as set forth in Section 2.03(b). On the 361^st 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 361^st day), the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Special 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 Special Interest when due, the Notes shall be subject to acceleration as provided in Section 6.02.

In order to elect to pay Special Interest as the sole remedy during the first 360 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 360-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 sole and absolute 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 and/or pre-funding satisfactory to the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, (i) the whole amount then due and payable on the Notes for principal and Special Interest, if any, with no interest accruing on any overdue principal and Special Interest, if any, unless Special Interest is payable pursuant to this Indenture on the required payment date, in which case such amounts

will accrue interest per annum at the then-applicable rate of Special Interest plus one percent from the required payment date and to the extent that Special Interest remains payable pursuant to this Indenture, subject to the enforceability of such interest pursuant to applicable law, and (ii) 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 or as trustee of an express trust, may institute a judicial proceeding (at law or in equity) 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.

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 Special 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, properly incurred expenses, properly incurred 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, properly incurred expenses, advances and properly incurred 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, properly incurred expenses, advances and properly incurred 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 or as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the compensation, properly incurred expenses, properly incurred disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

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 or property 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 to the Trustee and the Agents, including to their respective agents and counsel, under Section 7.06, including indemnity payments, and all fees, costs and expenses (including legal fees and expenses) due to the Trustee, the Paying Agent, the Transfer Agent, the Conversion Agent and the Note Registrar hereunder;

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of any Special Interest, if any, on, the Notes in default in the order of the date due of the payments of such Special Interest, with interest (to the extent that such interest is payable pursuant to this Indenture and has been collected by the Trustee) upon such overdue payments at the then applicable rate of Special Interest, if any, plus one percent, 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 Special Interest, if any, with interest (to the extent that any such interest is payable pursuant to this Indenture and has been collected by the Trustee) on the overdue principal and Special Interest, if any, at the then applicable rate of Special Interest, if any, 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, if any, or of any 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 any accrued and unpaid interest; and

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

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 Special Interest, if any, 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 and/or pre-funding satisfactory to it against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee has not complied with such request for 60 days after its receipt of such written notice, request and offer of security and/or indemnity and/or pre-funding satisfactory to it (as set forth in clause (c) above); and

(e) no written 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), it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are prejudicial to any other Holders. 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 Special Interest, if any, 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.

Section 6.07 Proceedings by Trustee. In case of an Event of Default, the Trustee may in its sole and absolute 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, (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction, and (c) subject Article 7, 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 the requisite number of Holders have offered to, and if requested, provided the Trustee indemnity and/or security and/or pre-funding satisfactory to the Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or direction. The Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or if it is not provided with security and/or indemnity and/or pre-funding to its satisfaction, or that the Trustee determines is unduly prejudicial to the rights of any other Holder (it being understood, subject to Article 7, that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to any other Holder). 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 (x) waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid Special Interest, if any, 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 and (y) rescind any resulting acceleration of the Notes and its consequences if (i) the Trustee has been paid all amounts owing to the Trustee under Section 7.06 hereunder, (ii) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (iii) all existing Events of Default (other than nonpayment of the principal of, and Special Interest, if any, on, the Notes that have become due solely by such acceleration) have been cured or waived. 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.

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 or, if later, within 15 days after written notice thereof is provided to the Trustee, 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; provided that the Trustee shall not be deemed to have knowledge of any occurrence of a Default or Event or Default unless it has received actual written notice thereof. 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 Special Interest, if any, 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 (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 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 or against 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 Special Interest, if any, on any Note (including, but not limited to, the Redemption Price, 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.

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 or the Conversion Agent hereunder need not be segregated from other funds or property except to the extent required by law. Neither the Trustee nor the Paying Agent nor the Conversion Agent shall be under any liability for interest on any money received by it hereunder. Any funds held by the Paying Agent or the Conversion Agent are held as a banker and shall not be subject to the applicable client money rules.

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 as mutually agreed to in writing between the Trustee and the Company (which sum shall be paid free and clear of deduction and withholding on account of taxation, set-off and counterclaim), and the Company will pay or

reimburse the Trustee upon its request for all expenses, disbursements and advances properly 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 properly incurred 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 as proven in a non-appealable decision in a court of competent jurisdiction. The Company also covenants to indemnify the Note Registrar, Transfer Agent, Conversion Agent, Paying Agent and Trustee (which for the purposes of this Section 7.06 shall be deemed to include its delegates, officers, directors, agents, counsel, employees, successors and assigns) 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 (including, reasonable legal fees and expenses) (whether arising from third party claims or claims by or against the Company) incurred without gross negligence or willful misconduct on the part of the Trustee, its delegates, officers, directors, agents, counsels, employees, successors or assigns, as the case may be, as proven in a non-appealable decision of a court of competent jurisdiction, 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 (including, without limitation, any and all attorney’s fees and properly incurred expenses) in the process of enforcing this indemnity. 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 Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06(a) shall extend to the delegates, officers, directors, agents, counsels and employees of the Trustee and any successor Trustee hereunder. Subject to Section 7.02(e), any gross negligence or willful misconduct of any agent, delegate, attorney or representative, in each case, of the Trustee, shall not affect indemnification of the Trustee.

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.

The obligations of the Company under this paragraph (a) shall survive the payment of the Notes, the termination or discharge of this Indenture and the resignation, replacement or removal of the Trustee, the Paying Agent, the Conversion Agent and the Note Registrar.

(b) The Paying Agent, the Transfer 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 Transfer Agent, the Conversion Agent and the Note Registrar for its out-of-pocket expenses (including fees and properly incurred expenses of counsel) by it in connection with the services rendered by it under this Indenture. The Company hereby agrees to indemnify the Paying Agent, the Transfer Agent, the Conversion Agent and the Note Registrar and their respective delegates, officers, directors, agents and employees and any successors thereto for, and to hold it harmless against, any loss, liability or expense (including fees and properly incurred expenses of counsel) without gross negligence or willful misconduct on its part arising out of or in connection with its acting as the Paying Agent, the Transfer 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 this Indenture and the resignation, replacement or removal of the Paying Agent, the Transfer Agent, the Conversion Agent and the Note Registrar. For the avoidance of doubt, in the event of any repurchase, the Company shall pay the Paying Agent additional compensation (to be agreed between the Company and the Paying Agent) for performing duties in respect of any repurchase where it is acting in a capacity similar to a tender agent.

Section 7.07 Officer’s 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 Officer’s Certificate delivered to the Trustee, and such Officer’s 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.

Section 7.08 Eligibility of Trustee. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America and any state thereof or Hong Kong that is authorized under such laws to exercise corporate trust power, that is subject to supervision or examination by federal or state authorities and that shall have a combined capital and surplus of at least US$50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of national, state or local supervising or examining authority, then, for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. 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 30 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 or following the removal of the Trustee in accordance with this Section 7.09, the resigning Trustee, (i) at the expense of the Company, may appoint its own successor trustee and/or (ii) at the expense of the Company, upon ten Business Days’ notice to the Company and the Holders, 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 (or since the date of this Indenture) 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 (or since the date of this Indenture) 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.

(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 (at the expense of the Company) 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 deliver or cause to be delivered 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 deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered 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.

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 of such application provided in accordance with Section 17.03 hereof), 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.

of the principal of and (subject to Section 2.03) accrued and unpaid Special Interest, if any, 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 Transfer Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary.

Upon the request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s 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, without liability, to accept such Officer’s 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.

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.

Notwithstanding any other provisions of this Indenture, the Trustee or the Note Registrar may make such reasonable regulations as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit.

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders 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 aggregate 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.

Section 9.06 Voting. The vote upon any resolution submitted to any meeting of Holders shall be by written ballot on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding aggregate principal amount of the Notes held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the

notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the aggregate principal amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

Any record so signed and verified shall be conclusive evidence of the matters therein

stated.

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 right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes.

ARTICLE 10

SUPPLEMENTAL INDENTURES

Section 10.01 Supplemental Indentures Without Consent of Holders. The Company, when authorized by the resolutions of the Board of Directors, and the Trustee, at the Company’s expense and direction, may from time to time and at any time amend or supplement this Indenture or the Notes for one or more of the following purposes:

(l) to conform the provisions of this Indenture or the Notes to the “Description of the Notes” section of the Offering Memorandum.

Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such amendment or supplement to this Indenture or the Notes, to make any further appropriate agreements and stipulations that may be therein contained, unless such supplemental indenture that affects the Trustee’s and/or any Agent’s (as the case may be) own rights, duties, privileges, liabilities or immunities under this Indenture or otherwise, in which case the Trustee may in its sole and absolute discretion, but shall not be obligated to, enter into such supplemental indenture.

Any amendment or supplement to this Indenture or the Notes 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 Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors, and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or the Notes or modifying in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall:

(a) reduce the amount of Notes whose Holders must consent to an amendment or waiver;

(b) reduce the rate of or change the stated time for payment of Special Interest, if any, on any Note;

(d) make any change that adversely affects the conversion rights of any Notes;

(e) reduce the Repurchase Price payable on the Repurchase Date, the Fundamental Change Repurchase Price or the Redemption Price of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

(j) make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in Section 6.02 or Section 6.09.

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless (i) the Trustee has not received an Officer’s Certificate and an Opinion of Counsel that such supplemental indenture is authorized and permitted by the terms of this Indenture and not contrary to law or (ii) such supplemental indenture affects the Trustee’s and/or Agent’s (as the case may be) own rights, duties, privileges, liabilities or immunities under this Indenture or otherwise, in which case the Trustee may in its sole and absolute discretion, but shall not be obligated to, enter into such supplemental indenture.

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be 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 send to the Holders (with a copy to the Trustee) 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 Supplemental Indenture in respect of Fundamental Change. If a Fundamental Change described in clause (d) of the definition thereof has occurred and the Newly Listed Equity has been accepted for listing on a Permitted Exchange, then, from and after the later to occur of (x) the date of such acceptance for listing on a Permitted Exchange and (y) the Effective Date of such Fundamental Change (the “New Listing Reference Date”), Section 14.07 of this Indenture will be deemed to apply mutatis mutandis as if the Reference Property for the Notes were the Newly Listed Equity. No later than five Business Days after the New Listing Reference Date, the Company shall execute with the Trustee a supplemental indenture containing such provisions that the Board of Directors determines in good faith are appropriate to preserve the economic interests of the Holders and are necessary to reflect the replacement of the ADSs (or Ordinary Shares or other Common Equity or Reference Property then underlying the Notes) with the Newly Listed Equity. The Company shall notify the Holders, the Trustee, the Conversion

Agent (if other than the Trustee) or any other agent appointed for such purpose in writing as promptly as reasonably practicable following the date the Company and the Trustee execute such supplemental indenture, and the Company shall substantially concurrently with such notice post such supplemental indenture on the Company’s website and disclose the same in a current report on Form 6-K (or any successor form) that is filed with the Commission.

Section 10.04 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, privileges, liabilities and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 10.05 Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Company, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee upon receipt of a Company Order by the Trustee and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

Section 10.06 Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by Section 17.06, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 10 and is permitted or authorized by this Indenture, is the valid and binding obligation of the Company enforceable in accordance with its terms, subject to customary assumptions, qualifications and exceptions.

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 the consolidated assets of the Company, its Subsidiaries and its Consolidated Affiliated Entities, taken as a whole, to another Person, unless:

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States, any State thereof, the district of Columbia, 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 assets of one or more Subsidiaries or Consolidated Affiliated Entities of the Company to another Person (other than a Subsidiary or a Consolidated Affiliated Entity of the Company), which properties and assets, if held by the Company instead of such Subsidiaries or Consolidated Affiliated Entities, would constitute all or substantially all of the 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 consolidated 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 (if not the 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 Special Interest, if any, 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 consolidated 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.

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. Except where the Company is the Surviving Person, no consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall be entitled to receive and conclusively rely on an Officer’s 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, that all conditions precedent thereto have been satisfied and that the Notes and such supplemental indenture are the legal, valid and binding obligations of the Successor Company, enforceable against it in accordance with its terms, subject to customary assumptions, qualifications, and exceptions.

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 Special Interest, if any, 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.

ARTICLE 13

INTENTIONALLY OMITTED

ARTICLE 14

CONVERSION OF NOTES

Section 14.01 Conversion Privilege. (a) 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 (i) subject to satisfaction of the conditions described in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding August 1, 2025 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), on or after August 1, 2025 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 18.3574 ADSs (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per US$1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.02, the “Conversion Obligation”). For the avoidance of doubt, “Conversion Rate” as of a particular date without setting forth a particular time on such date shall mean the Conversion Rate immediately after the close of business on such date.

(b) (i) Prior to the close of business on the Business Day immediately preceding August 1, 2025, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any ten consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per US$1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the ADSs on each such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per US$1,000 principal amount of Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price per US$1,000 principal amount of Notes) unless a Holder of at least US$2,000,000 principal amount of Notes provides the Company with reasonable evidence that the Trading Price per US$1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the ADSs on such Trading Day and the Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) in writing to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per US$1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per US$1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the ADSs and the Conversion Rate. At such time as the Company directs the Bid Solicitation Agent in writing to solicit bid quotations, the Company will provide the Bid Solicitation Agent with the names and contact details of the three independent nationally recognized securities dealers the Company selects, and the Company will direct those securities dealers to provide bids to the Bid Solicitation Agent. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not, when the Company is required to, instruct the Bid Solicitation Agent to determine the Trading Price per US$1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent in writing to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per US$1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the ADSs and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per US$1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the ADSs and the Conversion Rate for such date, the Company shall so notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee).

(ii) If, prior to the close of business on the Business Day immediately preceding August 1, 2025, the Company elects to:

(A) issue to all or substantially all holders of the Ordinary Shares (directly or in the form of ADSs) any rights, options or warrants (other than in connection with a stockholder rights plan so long as such rights have not separated from the Ordinary Shares (directly or in the form of ADSs) and are not exercisable until the occurrence of a triggering event, except that such rights will be deemed to be distributed under this Section 14.01(b)(ii)(A) upon their separation from the Ordinary Shares (directly or in the form of ADSs) or upon the occurrence of such triggering event) entitling them, for a period of not more than 60 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 share that is less than the average of the Last Reported Sale Prices of the ADSs, divided by 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; or

(B) distribute to all or substantially all holders of the Ordinary Shares (directly or in the form of ADSs) the Company’s assets, securities or rights to purchase securities of the Company, which distribution has a per share value, as determined by the Board of Directors, exceeding 10% of (i) the Last Reported Sale Price of the ADSs on the Trading Day preceding the date of announcement for such distribution, divided by (ii) the number of Ordinary Shares then represented by one ADS,

then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution (or if later in case of any separation of rights issued pursuant to a stockholder rights plan, as soon as practicable after the Company becomes aware that such separation has occurred). Once the Company has given such notice, a Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time.

The Notes will not become convertible on account of such distribution if each Holder participates, at the same time and upon the same terms as Holders of the Company’s ADSs and solely as a result of holding the Notes, in any of such distribution without having to convert its Notes as if such Holder held a number of ADSs equal to the Conversion Rate in effect on the Record Date for the ADS for such distribution multiplied by the principal amount (expressed in thousands) of Notes held by such Holder on such Record Date (for the avoidance of doubt, the Company shall still be required to send a notice of such distribution as described above).

(iii) If, prior to the close of business on the Business Day immediately preceding August 1, 2025, (1) a transaction or event that constitutes a Fundamental

Change or a Make-Whole Fundamental Change occurs, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or (2) if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the ADSs would be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the actual effective date of such transaction until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing as promptly as practicable following the date the Company publicly announces such transaction. If the Company does not provide such notice by the effective date of such transaction, then the last day on which the Notes are convertible shall be extended by the number of Business Days from, and including, the effective date thereof to, but not including, the date the Company provides the notice.

(iv) Prior to the close of business on the Business Day immediately preceding August 1, 2025, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the Last Reported Sale Price of the ADSs for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Company shall determine at the beginning of each calendar quarter commencing after June 30, 2021 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing if the Notes become convertible in accordance with this clause (iv).

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 16, then a Holder may surrender any or all of its Notes for conversion at any time prior to the close of business on the second Business Day prior to the Tax Redemption Date or Optional Redemption Date, as the case may be, even if the Notes are not otherwise convertible at such time. After that time, the right to convert such Notes on account of the Company’s delivery of the notice of redemption shall expire, unless the Company defaults in the payment of the Redemption Price on the Tax Redemption Date or the Optional Redemption Date, as the case may be, in which case a Holder may convert any or all of its Notes until the Redemption Price has been paid or duly provided for.

Section 14.02 Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each US$1,000 principal amount of Notes being converted, cash (“Cash Settlement”), ADSs together with cash, if applicable, in lieu of delivering any fractional ADSs (“Fractional ADSs”) (in accordance with subsection (j) of this Section 14.02 (“Physical Settlement”)) or a combination of cash and ADSs, together with cash, if applicable, in lieu of

delivering any Fractional ADS in accordance with subsection (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth in this Section 14.02.

(i) All conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to the close of business on the second Business Day prior to the related Tax Redemption Date or Optional Redemption Date, as applicable, and all conversions for which the relevant Conversion Date occurs on or after August 1, 2025 shall be settled using the same Settlement Method.

(ii) Except for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes but prior to the close of business on the second Business Day prior to the related Tax Redemption Date or Optional Redemption Date, as applicable, and any conversions for which the relevant Conversion Date occurs on or after August 1, 2025, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates.

(iii) If, in respect of any Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs after the date of issuance of a Redemption Notice with respect to the Notes and prior to the close of business on the second Business Day prior to the related Tax Redemption Date or Optional Redemption Date, as applicable, in such Redemption Notice or on or after August 1, 2025, no later than August 1, 2025, as the case may be), the Company elects a Settlement Method, the Company shall deliver a written notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be) to converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs after the date of issuance of a Redemption Notice with respect to the Notes and prior to the close of business on the second Business Day prior to the related Tax Redemption Date or Optional Redemption Date, as applicable, in such Redemption Notice or on or after August 1, 2025, no later than August 1, 2025) (in each case, the “Settlement Method Election Deadline”). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect its choice of Settlement Method and the Company shall be deemed to have elected the Default Settlement Method. If the Company delivers a Settlement Notice electing Combination Settlement (or is deemed to have elected Combination Settlement) in respect of its Conversion Obligation, but does not indicate a Specified Dollar Amount per US$1,000 principal amount of Notes to be converted in such Settlement Notice, the Specified Dollar Amount per US$1,000 principal amount of Notes to be converted shall be deemed to be US$1,000. For the avoidance of doubt, the Company’s failure to timely elect a Settlement Method or specify as applicable a Specified Dollar Amount shall not constitute a Default under this Indenture.

(iv) The Company may, by written notice to Holders, the Trustee and the Conversion Agent (if other than the Trustee), on or before August 1, 2025, change the Default Settlement Method or elect to irrevocably fix the Settlement Method to any Settlement Method that the Company is then permitted to elect (including Combination Settlement with a Specified Dollar Amount per US$1,000 principal amount of Notes of US$1,000 or with an ability to continue to set the Specified Dollar Amount per US$1,000 principal amount of Notes at or above any specific amount set forth in such election notice), in each case, that will apply to all Note conversions with a Conversion Date that is on or after the date the Company sends such notice. If the Company changes the Default Settlement Method or elects to irrevocably fix the Settlement Method, in either case, to Combination Settlement with an ability to continue to set the Specified Dollar Amount per US$1,000 principal amount of Notes at or above a specified amount, the Company shall, after the date of such change or election, as the case may be, inform Holders converting their Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing of such Specified Dollar Amount in respect of the relevant conversion or conversions no later than the relevant Settlement Method Election Deadline for such conversion or conversions, or, if the Company does not timely inform the Holders, the Trustee and the Conversion Agent of the Specified Dollar Amount, such Specified Dollar Amount shall be the specific amount set forth in the change or election notice or, if no specific amount was set forth in the change or election notice, such Specified Dollar Amount shall be deemed to be US$1,000 per US$1,000 principal amount of Notes. If the Company changes the Default Settlement Method or irrevocably fixes the Settlement Method, then the Company shall concurrently either post the Default Settlement Method or fixed Settlement Method, as applicable, on the Company’s website or disclose the same in a current report on Form 6- K (or any successor form) that is filed with the Commission. Notwithstanding the foregoing, no such change in the Default Settlement Method or irrevocable election will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Conversion Date pursuant to this Section 14.02. For the avoidance of doubt, such change or election (as the case may be), if made, will be effective without the need to amend this Indenture or the Notes, including pursuant to Section 10.02(a). However, the Company may nonetheless choose to execute such an amendment at the Company’s option.

(v) Subject to Section 14.03 and Section 14.04, the cash, ADSs or a combination of cash and ADSs, as applicable, in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver 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 in effect on the Conversion Date for such conversion;

(B) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each US$1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily

Conversion Values for each of the 40 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each US$1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive Trading Days during the related Observation Period.

(vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any Fractional ADS, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) in writing of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering Fractional ADSs. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(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, (1) comply with the procedures of the Depositary in effect at that time for converting a beneficial interest in a Global Note, and the procedures agreed between the Company and the ADS Depositary with respect to any ADSs issued upon conversion of the Notes prior to the Resale Restriction Termination Date, (2) and, if required, pay funds equal to Special Interest, if any, payable on the next Special Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h), and (3) prior to the Resale Restriction Termination Date, complete, sign and deliver a duly completed irrevocable notice to the Conversion Agent, the Company and the ADS Depositary 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, the Company and the ADS Depositary, 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 Special Interest, if any, payable on the next Special 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, or promptly following instructions 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 has not validly withdrawn such Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, in accordance with Section 15.03.

The delivery of the ADSs by the ADS Depositary to Holders upon conversion of their Notes or their designated transferees will be governed by the terms of the Deposit Agreement and, on or prior to the Resale Restriction Termination Date, by the terms of the Restricted Issuance Agreement and the procedures agreed between the Company and the ADS Depositary with respect to any restricted ADSs issued upon conversion of the Notes.

By converting a beneficial interest in a Global Note into ADSs, the Holder is deemed to represent to the Company and the ADS Depositary that such Holder is not an “affiliate” (as defined in Rule 144) of the Company and has not been an “affiliate” of the Company during the three months immediately preceding the Conversion Date.

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 Trustee or any Agent shall have any responsibility whatsoever with respect to the issuance and delivery of the ADSs to Holders who elect to convert their Notes.

(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. Except as set forth in Section 14.03(b) and Section 14.07(a), the Company shall pay and/or deliver, as the case may be, the consideration due in respect of the Conversion Obligation (x) on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement (provided that, with respect to any Conversion Date following the Special Interest Record Date immediately preceding the Maturity Date where Physical Settlement applies to the related conversion, the Company shall settle any such conversion on the Maturity Date), or (y) on the second Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of any other Settlement Method. If any ADSs are due to a converting Holder, the Company shall issue or cause to be issued, and deliver (if applicable) to such Holder, or such Holder’s nominee or nominees, the full number of ADSs to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion Obligation.

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and, upon receipt of a Company Order, 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, with payment of a sum sufficient to cover any documentary, stamp, issue, 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 any 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 Company 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 Company or the ADS Depositary, as applicable, receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence. The Company shall also pay and/or indemnify each Holder and beneficial owners of Notes and/or ADSs issuable upon conversion of the Notes for applicable fees (including, without limitation ADS depositary fees for the issuance and delivery of ADSs) and expenses payable to, or withheld by, the Depositary of the ADSs (including, for the avoidance of doubt, by means of a reduction in any amounts or property payable or deliverable in respect of any ADSs or in the value of deposited amounts or property represented by any ADSs) for the issuance of all ADSs deliverable upon conversion.

(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 Paying Agent shall make a notation on such Global Note as to the reduction in the principal amount represented thereby.

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid Special Interest, if any, except as set forth below and the Company will not adjust the Conversion Rate for any accrued and unpaid Special Interest on the Notes. 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 Special Interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid Special 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. Upon a conversion of Notes into a combination of cash and ADSs, accrued and unpaid Special Interest, if any, will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Special Interest Record Date and prior to the open of business on the immediately following Special Interest Payment Date, Holders of such Notes as of the close of business on such Special Interest Record Date will receive the full amount of Special Interest, if any, payable on such Notes on the corresponding Special Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Special Interest Record Date to the open of business on the immediately following Special Interest Payment Date must be accompanied by funds equal to the amount of Special Interest, if any, payable on the Notes so converted (regardless of whether the converting Holder was the holder of record on the corresponding Special Interest Record Date); provided that no such payment shall be required (1) for conversions following the Special Interest Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Tax Redemption Date or an Optional Redemption Date that is after a Special Interest Record Date and on or prior to the second Business Day immediately succeeding the corresponding Special Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Special Interest Record Date and on or prior to the second Business Day immediately succeeding the corresponding Special Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note.

(i) The Person in whose name the certificate for any ADSs shall be 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 (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. 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 delivering any Fractional ADS deliverable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of ADSs that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any Fractional ADSs remaining after such computation shall be paid in cash.

(k) In accordance with the Deposit Agreement or the Restricted Issuance Agreement, as applicable, the Company shall issue to the ADS Custodian such Ordinary Shares as may be required for the issuance of the ADSs upon conversion of the Notes, plus written delivery instructions for such ADSs, and any other information or documentation, shall pay the applicable ADS depositary fees (including, without limitation ADS depositary fees for the issuance and delivery of ADSs) and shall comply with the Deposit Agreement or the Restricted Issuance Agreement (as the case may be), in each case, as required by the ADS Depositary or the ADS Custodian in connection with each issue and deposit of Ordinary Shares and issuance and delivery of the corresponding 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 35^th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). The Company shall provide written notification to Holders and the Trustee (and the Conversion Agent, if other than 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. Neither the Trustee nor the Paying Agent nor the Conversion Agent shall be required to take any steps to ascertain whether a Make-Whole Fundamental Change or any event

which could lead to the occurrence of a Make-Whole Fundamental Change has occurred and shall not be liable to any person for any failure to do so.

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement 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 with a Conversion Date on or after 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. In such event, the Conversion Obligation will be determined and paid to Holders in cash on the fifth Business Day following the Conversion Date.

(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 consecutive 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.

(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:

	ADS Price
Effective Date	$38.91	$45.00	$50.00	$54.47	$60.00	$65.00	$70.00	$80.00	$90.00	$100.00	$125.00	$150.00	$200.00
January 26, 2021	7.3429	5.5902	4.4120	3.6040	2.8342	2.2982	1.8743	1.2621	0.8580	0.5844	0.2142	0.0640	0.0000
February 1, 2022	7.3429	5.5902	4.3642	3.5131	2.7128	2.1638	1.7360	1.1308	0.7424	0.4871	0.1580	0.0369	0.0000
February 1, 2023	7.3429	5.4740	4.1370	3.2526	2.4418	1.9000	1.4877	0.9230	0.5757	0.3565	0.0934	0.0123	0.0000
February 1, 2024	7.3429	4.7527	3.5390	2.7358	2.0023	1.5166	1.1520	0.6658	0.3810	0.2121	0.0343	0.0000	0.0000
February 1, 2025	7.3429	4.4509	3.0858	2.2205	1.4758	1.0185	0.7014	0.3275	0.1453	0.0575	0.0001	0.0000	0.0000
February 1, 2026	7.3429	3.8648	1.6426	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000

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$200.00 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$38.91 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 25.7003 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 (i) redeem the Notes in respect of a Change in Tax Law pursuant to Section 16.01 or (ii) redeem the Notes at the Company’s option pursuant to Section 16.02, in each case, 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 such 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 or redeem the Notes at the Company’s option if the relevant Notice of Conversion is received by the Conversion Agent 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 second Business Day immediately preceding the Tax Redemption Date or the Optional Redemption Date, as the case may be (or, if the Company fails to pay the Redemption Price, such later date on which the Company pays the Redemption Price).

The number of Additional ADSs by which the Conversion Rate will be increased in the event the Company elects to redeem the Notes pursuant to Article 16 hereof 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. “Redemption Reference Date” means the date the Company delivers the relevant Redemption Notice. “Redemption Reference Price” means, for any conversion in connection with the Company’s election to redeem the Notes in respect of a Change in Tax Law pursuant to Section 16.01 or redeem the Notes at the Company’s option pursuant to Section 16.02, as the case may be, the average of the Last Reported Sale Prices of the ADSs over the five consecutive Trading Day period ending on, and including the Trading Day immediately preceding, the date the Company delivers the relevant Redemption Notice.

If a conversion in connection with a notice of redemption would also be deemed to be in connection with a Make-Whole Fundamental Change, then, solely for purposes of that conversion, a Holder of the Notes to be converted will be entitled to a single increase to the Conversion Rate with respect to the first to occur of the Effective Date of the Redemption Notice or the Make- Whole Fundamental Change, as applicable, and the later event shall be deemed not to have occurred for purposes of such conversion for purposes of Section 14.02 and Section 14.03.

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 described in clause (b) below entitling holders of the Ordinary Shares for a period of not more than 60 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.

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 or verify 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 in writing to the Holders, the Trustee, the Paying Agent and the 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:


CR₁ = CR₀ Í	OS₁
		OS₀

where,
CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend 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 open of business on such Ex-Dividend Date or Effective Date, as applicable;
OS₀	=	the number of Ordinary Shares outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date, as applicable (before giving effect to any such dividend, distribution, split or combination); 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 open of business on the Ex-Dividend 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.

(b) If the Company issues to all or substantially all holders of the Ordinary Shares (directly or in the form of ADSs) (other than in connection with a stockholder rights plan) any rights, options or warrants entitling them, for a period of not more than 60 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:


CR₁ = CR₀ Í	OS₀ + X
		OS₀ + Y

where,
CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the ADSs for such issuance;
CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
OS₀	=	the number of Ordinary Shares outstanding immediately prior to the open of business on such Ex-Dividend 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 distributed and shall become effective immediately after the open of business on the Ex-Dividend 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). To the extent 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 had the increase to the Conversion Rate for such issuance been made on the basis of only the rights, options or warrants, if any, actually issued.

For purposes of this Section 14.04(b) and Section 14.01(b)(ii)(A), 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), (iii) except as otherwise described below in this Indenture, rights issued pursuant to any stockholder rights plan of the Company then in effect, (iv) distributions of Reference Property issued in exchange for, or upon conversion of, the ADSs or the Ordinary Shares as described under Section 14.07 and (v) 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:


CR₁ = CR₀ Í	SP₀
		SP₀ – FMV

where,
CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the ADSs for such distribution;
CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend 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 Ex-Dividend Date for the ADSs for such distribution.

Any increase made under the foregoing portion of this Section 14.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for the ADSs for such distribution. If such distribution is not so paid or made in full, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually paid or made. 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:


CR₁ = CR₀ Í	FMV₀ + MP₀
		MP₀


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 immediately after the close of business on the last Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references in the portion of this Section 14.04(c) with respect 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, such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, the reference to “10” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between (and including, in each case) the Ex-Dividend Date for such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day.

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 Ex-Dividend 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 “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend 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 open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b).

(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:


CR₁ = CR₀ Í	SP₀
		SP₀ – C

where,
CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the ADSs for such dividend or distribution;
CR₁	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
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

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) (for the avoidance of doubt, without giving effect to any applicable fees and expenses payable to, or withheld by, the ADS Depositary with respect to such distribution).

Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of business on the Ex-Dividend 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.

(e) If the Company or any of its Subsidiaries or its 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 Tender/Exchange Offer Consideration (as defined below) 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:


CR₁ = CR₀ Í	AC + (SP₁ Í OS₁)
		OS₀ Í SP₁


where,
CR₀	=	the Conversion Rate in effect immediately prior to the close of business on the 10^th 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 10^th 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 as of the time such tender or exchange offer expires (the “Tender/Exchange Offer Consideration”)) 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 10^th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during 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” or “10^th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the expiration date of such tender or exchange offer to, and including such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including the Trading Day next succeeding the expiration date of such tender or exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the expiration date of such tender or exchange offer to, and including, such Trading Day in determining the Conversion Rate as of such Trading Day. For the avoidance of doubt, no adjustment under this Section 14.04(e) with will be made if such adjustment would result in a decrease in the Conversion Rate (other than, for the avoidance of doubt, any readjustment described in the immediately succeeding paragraph).

(f) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and (x) in the case of Physical Settlement, a Holder that has converted its Notes on or after such Ex- Dividend Date and on or prior to the related Record Date would be treated as the record holder of the ADSs as of the related Conversion Date as described under Section 14.02(i) or (y) in the case of Combination Settlement, any Trading Day in the Observation period for such conversion occurs on or after such Ex-Dividend Date and on or prior to the related Record Date, and the consideration due with respect to such Trading Day includes any whole ADSs, in each case (x) and (y), based on an adjusted Conversion Rate for such Ex-Dividend Date and such ADSs due upon conversion would be entitled to participate in the related dividend, distribution or other event giving rise to the adjustment, then, notwithstanding the Conversion Rate adjustment

provisions in this Section 14.04, (A) in the case of Physical Settlement, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder, and instead, such Holder shall be treated as if such Holder were the record owner of the ADSs on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment and (B) in the case of Combination Settlement, the Conversion Rate adjustment related to such Ex-Dividend Date will be made for such conversion in respect of such Trading Day, but the ADSs issuable with respect to such Trading Day based on such adjusted Conversion Rate will not be entitled to participate in the related dividend, distribution or other event giving rise to such adjustment.

(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 consolidated Subsidiaries or its Consolidated Affiliated Entities;

(iii) upon the repurchase of any Ordinary Shares pursuant to an open-market share repurchase program or other buyback transaction that is not a tender offer or exchange offer of the nature described in clause (e) of this Section 14.04 above;

(iv) 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;

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

(vi) for accrued and unpaid Special 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 deliver to the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth (i) the adjusted Conversion Rate, (ii) the subsection of this Section 14.04 pursuant to which after such adjustment has been made, showing in reasonable detail the facts upon which such adjustment is based, and (iii) the date as of which such adjustment is effective, and such Officer’s Certificate shall be conclusive evidence of the accuracy of such adjustment absent manifest error. Unless and until the Conversion Agent and a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Conversion Agent and 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 deliver 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. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein.

(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.

Section 14.05 Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, the ADS Price for purposes of a Make- Whole Fundamental Change or the Redemption Reference Price for purposes of the Company’s election to redeem the Notes over a span of multiple days, the Board of Directors shall, in good faith, make appropriate adjustments (without duplication in respect of any adjustment made pursuant to the provisions described under Section 14.04 above) 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 Ex-Dividend 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, ADS Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts 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 and that Physical Settlement were applicable).

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 ADSs or Ordinary Shares (other than changes resulting from a subdivision or combination and changes in par value or from par value to no par value (or vice versa)),

(ii) any consolidation, merger, combination or similar transaction involving the Company,

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

(iv) any statutory share exchange,

in each case, as a result of which the ADSs or 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, 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 such Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash,

(II) any ADSs that the Company would have been required to deliver 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 and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property that a holder of one ADS would have received in such transaction. If the Reference Property consists of only cash in such Merger Event, then for all conversions that occur on or after the effective date of such Merger Event (i) the Company shall be deemed to elect Physical Settlement, (ii) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased as described under Section 14.03), multiplied by the price

paid per ADSs in such Merger Event and (iii) the Company shall satisfy its Conversion Obligation by paying cash to converting Holders on the fifth Business Day immediately following the Conversion Date.

If the Merger Event causes the ADSs or 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 (i) 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) and (ii) contain such other provisions that the Board of Directors determines in good faith are appropriate to preserve the economic interests of the Holders and to give effect to the provisions described in this Section 14.07. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (other than cash) 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. The Company shall, as soon as reasonably practicable after the Effective Date of such transaction, post such supplemental indenture on the Company’s website and disclose the same in a current report on Form 6-K (or any successor form) that is filed with the Commission.

(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 cash, ADSs or a combination of cash and ADSs, as applicable, 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 upon conversion of the Notes, if any, in accordance with the terms of this Indenture, the Notes and the Deposit Agreement or the Restricted Issuance Agreement, as applicable, upon conversion of the Notes.

Section 14.09 Responsibility of Trustee and the Agents. The Trustee, the Paying Agent and any other the 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 in this Indenture or in any supplemental indenture provided to be employed, in making the same. The Trustee, the Paying Agent and the Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of the 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, the Paying Agent and the Conversion Agent make no representations with respect thereto. Neither the Trustee, the Transfer Agent 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 in this Article 14. Without limiting the generality of the foregoing, neither the Trustee, the Paying Agent 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 Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. The parties agree that all notices to the Trustee, the Paying Agent or the Conversion Agent under this Article 14 shall be in writing.

Neither the Trustee nor any Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor unless the Company has delivered to the Trustee, the Paying Agent and the Conversion Agent, the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights. The Trustee, the Paying Agent and the Conversion Agent may conclusively rely on such notices, and the Company agrees to deliver such written notices to the Trustee, the Paying Agent and the Conversion Agent promptly after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b).

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; 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.

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, if any, 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. Except as provided in Section 10.03, if the Ordinary Shares cease to be represented by ADSs issued under the Deposit Agreement, 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 February 1, 2025 (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 Special Interest, if any, to, but not including, the Repurchase Date (unless the Repurchase Date falls after a Special Interest Record Date but on or prior to the Special Interest Payment Date to which such Special Interest Record Date relates, in which case the Company shall instead pay on or, at its election, before the Special Interest Payment Date the full amount of accrued and unpaid Special Interest, if any, to the Holder of record as of the close of business on such Special Interest Record Date, and the Repurchase Price will be equal to 100% of the principal amount of the Notes to be repurchased).

Notwithstanding the foregoing, the Company shall not be required to repurchase, or to make an offer to repurchase, the Notes on February 1, 2024 if (i) (x) a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above and (y) an owner of a beneficial interest in any Note repurchased by such third party will not receive a lesser amount (as a result of taxes, additional expenses or for any other reason) than such owner would have received had the Company repurchased such Note as set forth above, or (ii) the Company has called the Notes for redemption as described under Section 16.01 with a Redemption Date on February 1, 2024.

Not later than 20 Business Days prior to the Repurchase Date, the Company shall provide written notice (the “Company Notice”) to the Trustee or other agent appointed for such purpose, to the Paying Agent, the Conversion Agent if other than the Trustee 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 and to the Conversion Agent if other than the Trustee). 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;

(iv) the name and address of the Conversion Agent, Paying Agent or other agent appointed for such purpose;

(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 Paying Agent shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, a final copy of the notice to be delivered by the Paying Agent shall be provided by the Company to the Paying Agent.

Concurrently 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 Paying Agent or any other agent appointed for such purpose 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 Note Registrar at any time after delivery of the Repurchase Notice (together with all necessary endorsements) at the Paying Agent Office or specified office of another agent appointed for such purpose, 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;

(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. If the Notes are not in certificated form, to exercise the repurchase right, Holders must surrender their Notes in accordance with applicable DTC procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent or other agent appointed for such purpose the Repurchase Notice contemplated by this Section 15.01 shall have the right to withdraw, in whole or in part, such Repurchase Notice 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 Paying Agent or other agent appointed for such purpose in accordance with Section 15.03.

The Paying Agent or other agent appointed for such purpose shall as soon as practicable 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 to the Holders, the Trustee, the Paying Agent or other agent appointed for such purpose 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 any accrued and unpaid Special Interest thereon to, but not including, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Special Interest Record Date but on or prior to the Special Interest Payment Date to which such Special Interest Record Date relates, in which case the Company shall instead pay on, or at its election, before the Special Interest Payment Date the full amount of accrued and unpaid Special Interest, if any, to Holders of record as of the close of business on such Special Interest 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. The Trustee, the Conversion Agent, Paying Agent or any other agent appointed for such purpose shall have no responsibility to determine, calculate or verify the Fundamental Change Repurchase Price. The Trustee, the Conversion Agent, the Paying Agent or any other agent appointed for such purpose shall not be required to take any steps to ascertain whether a Fundamental Change or any event which could lead to the occurrence of a Fundamental Change has occurred and shall not be liable to any person for any failure to do so.

Notwithstanding the foregoing, the Company shall not be required to repurchase, or to make an offer to repurchase, the Notes upon a Fundamental Change if (i) a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above and (ii) an owner of a beneficial interest in any Note repurchased by such third party will not receive a lesser amount (as a result of taxes, additional expenses or for any other reason) than such owner would have received had the Company repurchased such Note as set forth above.

100

(b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon:

(i) delivery to the Paying Agent (or other agent appointed for this purpose) 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 Paying Agent or other agent appointed for such purpose at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the specified office as set forth in the Fundamental Change Repurchase Notice, 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. If the Notes are not in certificated form, to exercise the repurchase right, Holders must surrender their Notes in accordance with applicable DTC procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent 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 prior to the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a duly completed written notice of withdrawal to the Paying Agent in accordance with Section 15.03.

The Paying Agent or other agent appointed for such purpose shall promptly notify the Company and the Trustee of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

101

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 to the extent such Holder has also surrendered a Repurchase Notice with respect to such Note in accordance with Section

15.01 and not validly withdrawn such Repurchase Notice in accordance with Section 15.03.

(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, the Trustee (and the Conversion Agent, Paying Agent and any other agent appointed for this purpose, in each case, if other than 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. Concurrently 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 and whether such events also constitute a Make-Whole Fundamental Change;

(ii) the effective 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, the Paying Agent, the Conversion Agent or any other agent appointed for repurchase, if applicable;

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate as a result of such Fundamental Change if it is a Make-Whole Fundamental Change;

(viii) if applicable, 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.

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.

102

(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 Paying Agent or other agent appointed for such purpose in accordance with this Section 15.03 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 Paying Agent (or any other agent appointed for this purpose 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 11:00 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 Paying Agent (or other agent appointed for this purpose by the Company) and the

103

Trustee, as applicable, 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 Paying Agent or other agent appointed by the Company by the Holder thereof in the manner required by Section 15.01 or Section 15.02, as applicable, by a wire transfer of the immediately available funds in 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.

(b) If by 11:00 a.m., New York City time, on the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, the Paying Agent (or other agent appointed for this purpose 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 to the Paying Agent or other agent appointed for such purpose 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) Special Interest, if and to the extent that any such accrued and unpaid Special Interest exists as of such date, 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 Paying Agent or any other agent appointed for such purpose) 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, and the right of the Holder on the applicable Special Interest Record Date to receive previously accrued and unpaid Special Interest, if any, upon delivery or transfer of the Notes to the extent not included in the Repurchase Price or Fundamental Change Repurchase Price, as the case may be).

15.01 or Section 15.02, the Company shall execute and the Trustee, upon receipt of a Company Order, 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.

104

To the extent that the provisions of any securities laws or regulations enacted or adopted after the date on which the Notes are first issued conflict with the provisions of this Indenture relating to the Company’s obligations to repurchase the Notes upon a Fundamental Change, the Company shall comply with the such securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Indenture by virtue of such conflict.

ARTICLE 16

OPTIONAL REDEMPTION

Section 16.01 Optional Redemption for Changes in the Tax Law of the Relevant Taxing Jurisdiction. If the Company has, or on the next Special 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 which is not publicly announced before, and becomes effective on or after January 21, 2021 (or, if the Relevant Taxing Jurisdiction was not a Relevant Taxing Jurisdiction on such date, the date on which such Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction under this Indenture) in the laws or any rules or regulations of a Relevant Taxing Jurisdiction; or

(b) any change which is not publicly announced before, and becomes effective on or after January 21, 2021 (or, if the Relevant Taxing Jurisdiction was not a Relevant Taxing Jurisdiction on such date, the date on which such Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction under this Indenture) in any written 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 thereof (the “Redemption Price”), plus accrued and unpaid Special Interest, if any, to, but not including the date fixed by the Company for redemption, which shall be on or prior to the 40^th Scheduled Trading Day immediately before the Maturity Date (the “Tax 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) prior to or simultaneous with the Tax Redemption Notice, the Company delivers to the Trustee an opinion of outside legal counsel or a tax advisor of recognized standing in the Relevant Taxing Jurisdiction that the Company has or will become, on or before the Tax Redemption Date, obligated to pay such Additional Amounts as a result of a Change in Tax Law and an Officer’s Certificate stating that such obligation cannot be avoided by taking reasonable measures available to the Company. The Trustee shall and is entitled to conclusively rely upon such opinion and Officer’s Certificate (without further investigation and enquiry) and it shall be conclusive and binding on the Holders.

105

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 and any other tax collected at source 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 Special Interest Record Date and on or prior to the corresponding Special Interest Payment Date, the Company shall pay or cause the Paying Agent to pay, on or at its election, before such Special Interest Payment Date, pay the full amount of accrued and unpaid Special Interest, if any, and any Additional Amounts with respect to such Special Interest, due on such Special Interest Payment Date to the record holder of the Notes as of the close of business on the Special Interest Record Date corresponding to such Special Interest Payment Date, and the Redemption Price payable to any Holder (other than a Holder that elects to not have its Notes redeemed pursuant to the provisions described below) shall be equal to 100% of the principal amount of such Note to be redeemed, including, for the avoidance of doubt, any Additional Amounts with respect to such Redemption Price. The Company shall notify the Trustee and the Paying Agent in writing of its election and the date on which such Special Interest, if any, and any Additional Amounts with respect to such Special Interest shall be paid at the time the Company provides notice of such redemption.

The Company shall give the Trustee, the Paying Agent and Holders of Notes not less than 50 Scheduled Trading Days’ but no more than 60 Scheduled Trading Days’ notice of redemption (a “Tax Redemption Notice”) prior to the Tax Redemption Date, which will include the Redemption Price, the Tax Redemption Date and the Settlement Method that will apply to all conversions with a Conversion Date that occurs on or after the date the Company sends such Tax Redemption Notice and before the close of business on the second Business Day immediately before the related Tax Redemption Date. Concurrently with providing such notice, which will include the Redemption Price, the Tax Redemption Date and the Settlement Method that will apply to all conversions with a Conversion Date that occurs on or after the date the Company sends such notice of redemption and before the close of business on the second Business Day immediately before the related Tax Redemption Date, 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 Tax Redemption Date must be a Business Day. The Tax Redemption Notice shall not be revoked or subject to conditions, and outstanding Notes will become due and payable at the Redemption Price on the Tax Redemption Date specified in the related Tax Redemption Notice.

At the Company’s prior written request, the Trustee shall give the Tax Redemption Notice in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee not later than the close of business five Business Days prior to the date the Tax Redemption Notice is to be sent (unless a shorter period shall be satisfactory to the Trustee), an Officer’s Certificate and a Company Order requesting that the Trustee give such Tax Redemption Notice together with the final form of the Tax Redemption Notice to be given setting forth the information to be stated therein as provided in the preceding paragraph. The Tax Redemption Notice, if given in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give

106

such Tax Redemption Notice or any defect in the Tax Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the Tax Redemption of any other Note.

Upon receiving such notice of redemption, each Holder shall have the right to elect to not have its Notes redeemed, provided that (i) 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 on the Repurchase Date, at maturity or otherwise, and whether in cash, ADSs, or combination thereof, Reference Property or otherwise) after the Tax Redemption Date (or, if the Company fails to pay the Redemption Price on the Tax Redemption Date, such later date on which the Company pays the Redemption Price), and (ii) all future payments with respect to such Notes shall be subject to the deduction or withholding of any taxes of such Relevant Taxing Jurisdiction required by law to be deducted or withheld as a result of such Change in Tax Law; provided further 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.

Subject to the applicable procedures of DTC in the case of Global Notes, a Holder electing to not have its Notes redeemed must deliver to the Trustee and the Paying Agent a written notice of election so as to be received by the Trustee and Paying Agent no later than the close of business on the second Business Day immediately preceding the Tax 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 second Business Day immediately preceding the Tax Redemption Date (or, if the Company fails to pay the Redemption Price on the Tax 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 by the Company or its successor if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Tax Redemption Date.

Section 16.02 Optional Redemption by the Company. The Company may not redeem the Notes prior to February 6, 2024, except under the circumstances described in Section 16.01.

(a) On or after February 6, 2024 and on or prior to the 40^th Scheduled Trading Day immediately prior to the Maturity Date, the Company may redeem for cash all or any portion of the Notes, at its option, if the Last Reported Sale Price of the ADSs has been at least 130% of the Conversion Price then in effect on (i) each of at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the

Trading Day immediately prior to the date the Company provides a notice of redemption and (ii) the Trading Day immediately preceding the date the Company sends such notice.

(b) In case the Company exercises its option to redeem all or, as the case may be, any part of the Note, it shall fix a date for redemption (the “Optional Redemption Date”) and shall give the Holders, Trustee, Conversion Agent, Paying Agent and each Holder of the Notes not less than 50 Scheduled Trading Days’ but no more than 60 Scheduled Trading Days’ notice (an “Optional Redemption Notice”) prior to the Optional Redemption Date, and the redemption price (the “Redemption Price”) will be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid Special Interest, if any, to, but not including, the Optional Redemption Date (unless the Optional Redemption Date falls after a Special Interest Record Date but on or prior to the Special Interest Payment Date to which such Special Interest Record Date relates, in which case the Company shall instead pay on, or at its election, before the Special Interest Payment Date the full amount of accrued and unpaid Special Interest, if any, to the holder of record on such Special Interest Record Date, and the Redemption Price shall be equal to 100% of the principal amount of the Notes to be redeemed). The Optional Redemption Date must be a Business Day. The Company shall send to each Holder and the Trustee written Optional Redemption Notice containing certain information set forth in this Indenture, including:

(i) the Optional Redemption Date;

(ii) the Redemption Price;

(iii) the Settlement Method that will apply to all conversions with a Conversion Date that occurs on or after the date the Company sends such Optional Redemption Notice and before the close of business on the second Business Day immediately before the related Optional Redemption Date;

(iv) that on the Optional Redemption Date, the Redemption Price will become due and payable for each Note to be redeemed, and that Special Interest thereon, if any, shall cease to accrue on and after the Optional Redemption Date unless the Company defaults in the payment of the Redemption Price;

(v) the place or places where the Notes subject to such redemption are to be surrendered for payment of the Redemption Price;

(vi) that Holders may surrender Notes for conversion at any time prior to the close of business on the second Business Day prior to the Optional Redemption Date (unless the Company fails to pay the Redemption Price, in which case a Holder of Notes may convert such Notes until the Business Day immediately preceding the date on which the Redemption Price has been paid or duly provided for);

(vii) the Conversion Rate and, if applicable, the number of Additional ADSs added to the Conversion Rate in accordance with Section 14.03;

(viii) the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes and that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number listed in such notice or printed on the Notes; and

108

(ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed, and that upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued.

An Optional Redemption Notice shall be irrevocable. At the Company’s prior written request, the Paying Agent shall give the Optional Redemption Notice in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Paying Agent not later than the close of business five Business Days prior to the date the Redemption Notice is to be sent (unless a shorter period shall be satisfactory to the Trustee), an Officer’s Certificate and a Company Order requesting that the Paying Agent give such Optional Redemption Notice together with the Optional Redemption Notice to be given setting forth the information to be stated therein as provided in the preceding paragraph. The Optional Redemption Notice, if given in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Optional Redemption Notice or any defect in the Optional Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the Optional Redemption of any other Note.

Concurrently 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.

If the Company decides to redeem fewer than all of the outstanding Notes, the Trustee will select the Notes to be redeemed (in principal amounts of US$1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee considers to be fair and appropriate and, in the case of a Global Note, in accordance with, and subject to, DTC’s applicable procedures.

If the Trustee (or DTC with respect to Global Notes) selects a portion of a Holder’s Notes for partial redemption and such Holder converts a portion of such Notes, the converted portion shall be deemed to be from the portion selected for redemption. In the event of any redemption in part, the Company shall not be required to register the transfer of or exchange any Note so selected for redemption, in whole or in part, except the unredeemed portion of any such Note being redeemed in part.

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 the Optional Redemption Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

21VIANET GROUP, INC.

0.00% Convertible Senior Note due 2026

This Note is one of a duly authorized issue of Notes of the Company, designated as its 0.00% Convertible Senior Notes due 2026 (the “Notes”), initially limited to the aggregate principal amount of US$600,000,000, subject to Section 2.10 of the Indenture, all issued or to be issued under and pursuant to an Indenture dated as of January 26, 2021 (the “Indenture”), between the Company and Citicorp International Limited, 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, indemnifications, 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.

In the case certain Events of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and any Special Interest on, all Notes may be declared, by either the Trustee may, or Holders of at least 25% in aggregate principal amount of Notes then outstanding by notice to the Company or the Trustee may, and the Trustee at the written request of such Holders shall (subject to being indemnified and/or secured and/or pre-funded to its satisfaction) declare 100% of the principal of and accrued and unpaid Special Interest, if any, on all the Notes 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 any Special 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 or cause the Paying Agent to 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.

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 Special Interest, if any, 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. 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 February 6, 2024, except in the event of certain Changes in Tax Law as described in Section 16.01 of the Indenture. The Notes shall be redeemable at the Company’s option in certain circumstances on or after February 6, 2024 and on or prior to the 40^th Scheduled Trading Day immediately before the Maturity Date in accordance with the terms and subject to the conditions specified in 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, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading 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 cash, ADSs or a combination of cash and ADSs, as
