      to which provisions reference is hereby made. The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Notes, which may
      be issued from time to time in accordance herewith, and shall not apply to any other Securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other Securities specifically incorporates such changes,
      modifications and supplements. For all purposes under the Base Indenture, the Notes shall constitute a single series of Securities. The provisions of this Supplemental Indenture shall supersede, with respect to the Notes, any conflicting provisions
      in the Base Indenture.

     

    Section 2.02.  Designation and Amount. The Notes are hereby created and authorized as a single series of Securities under the Base
      Indenture. The Notes shall be designated as the “0.25% Convertible Senior Notes due 2026.” The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is initially limited to US$2,875,000,000, subject to
      Section 2.08 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes to the extent expressly permitted under the Indenture.

     

    Section 2.03.  Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially
      in the respective forms set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution
      and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby. In the case of any conflict between the Notes and the Indenture, the provisions of the Indenture shall control and govern.

     

    Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of the Indenture as may be required by the Depositary, or as may be
      required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or traded or designated for issuance or to conform
      with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject.

     

    

    
      14

      
        


    

    Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the Officer executing the same may approve (execution thereof to be conclusive evidence of
      such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated
      quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

     

    Each Global Note shall represent such principal amount of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to
      time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be increased or reduced to reflect redemptions, repurchases, cancellations, conversions, transfers or exchanges permitted
      hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Registrar, at the direction of the Trustee in such manner and upon
      instructions given by the Holder of such Notes in accordance with the Indenture. Payment of principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, a Global Note
      shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is provided for herein.

      months, on the basis of actual days elapsed over a 30-day month.

     

    (b)          Section 3.08(a) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.04(b), and any reference in the Base Indenture to Section 3.08(a) shall, with respect
      to the Notes, be deemed to refer instead to this Section 2.04(b), as the context may require. The Person in whose name any Note (or its Predecessor Note) is registered on the Register at the close of business on any Regular Record Date with respect
      to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the Company maintained by the Company for such purposes in the contiguous United

      Holders or, upon application by such Holder to the Trustee not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect
      until the Holder notifies, in writing, the Trustee to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee.

     

    (c)          Section 3.08(b) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.04(c), and any reference in the Base Indenture to Section 3.08(b) shall, with respect
      to the Notes, be deemed to refer instead to this Section 2.04(c), as the context may require. Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate per
      annum borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in
      each case, as provided in clause (i) or (ii) below:

     

    (i)           The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a
      special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the
      proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee in its sole discretion shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an
      amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be
      held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not
      less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee and Holders of the proposed payment of such
      Defaulted Amounts and the special record date therefor, at each Holder’s address as it appears in the Register or by electronic means to the Depositary in the case of Global Notes, not less than 10 days prior to such special record date. Notice of
      the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the
      close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.04(c). The Trustee shall have no responsibility whatsoever for the calculation of any Defaulted Amounts.

    (ii)          The Company may make payment of any Defaulted Amounts to the Persons in whose name the Notes (or their respective Predecessor Notes) are registered in any other lawful manner not
      inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after
      written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

      to the Notes, be deemed to refer instead to this Section 2.05(b), as the context may require. No service charge shall be imposed by the Company, the Transfer Agent, the ADS Depositary, the Registrar, the co-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 or similar issue or transfer 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 be responsible for the ADS Depositary’s fees for issuance
      of the ADSs.

     

    (c)          Section 3.06(g) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.05(c), and any reference in the Base Indenture to Section 3.06(g) shall, with respect

      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 or (iv) any Notes between a Regular Record Date and corresponding Interest Payment Date.

     

    (d)          So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to 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 the Indenture and the applicable procedures of the Depositary therefor.

     

    The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note
      shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

    (e)          Section 3.06(c) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.05(e), and any reference in the Base Indenture to Section 3.06(c) shall, with respect
      to the Notes, be deemed to refer instead to this Section 2.05(e), as the context may require.

     

    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, (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, or (iv) the Company or a beneficial owner of the Affiliate Notes requests that the Affiliate Notes 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 or Affiliate Notes, as applicable, 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 Trustee 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(e) 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 clauses (iii) and (iv) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee 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 Trustee 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 Trustee, to reflect such reduction or increase.

     

    None of the Company, any agent of the Company, the Trustee, the Paying Agent, the Conversion Agent or any other agent of the Trustee shall have any responsibility or liability for the payment of amounts to beneficial
      holders, any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

     

    

    
      18

      
        


    

    (f)           Any Note or ADS delivered upon the conversion or exchange of any Note (including any Affiliate Note) that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the
      Company during the three months immediately preceding) may not be resold by such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the
      Securities Act in a transaction that results in such Note or ADS, as the case may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Company shall cause any Note that is repurchased or owned by it to
      be surrendered to the Paying Agent for cancellation in accordance with Section 2.07.

     

    Section 2.06.  Mutilated, Destroyed, Lost or Stolen Notes.

     

    (a)          Section 3.07(b) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.06(a), and any reference in the Base Indenture to section 3.07(b) shall, with respect
      to the Notes, be deemed to refer instead to this Section 2.06(a), as the context may require. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with
      Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender
      thereof except in the case of a mutilated Note), as the case may be.

     

    (b)          Section 3.07(c) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 2.06(b), and any reference in the Base Indenture to section 3.07(c) shall, with respect
      to the Notes, be deemed to refer instead to this Section 2.06(b), as the context may require. No service charge shall be imposed by the Company, the Transfer Agent, the ADS Depositary, the Registrar, any co-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 or similar issue or transfer 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.

     

    Section 2.07.  Cancellation of Notes Paid, Converted, Etc. Section 3.09 of the Base Indenture shall, with respect to the Notes, be
      superseded in its entirety by this Section 2.07, and any reference in the Base Indenture to Section 3.09 shall, with respect to the Notes, be deemed to refer instead to this Section 2.07, as the context may require. The Company shall cause all Notes
      surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries, Consolidated Affiliated
      Entities or Affiliates), to be delivered and surrendered to the Trustee for cancellation. All Notes delivered to the Trustee 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 the Indenture. The Trustee shall dispose of all canceled Notes held by it in accordance with its customary procedures and, after such disposition, shall deliver a
      certificate of such cancellation and disposition to the Company, at the Company’s written request in a Company Order. 

     

    

    
      19

      
        


    

    Section 2.08. Additional Notes; Repurchases. The Company may, without the consent of, or notice to, the Holders and notwithstanding
      Section 2.02, reopen the 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, 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 one or more separate CUSIP numbers. 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 required by Section 16.01 of the Base Indenture. In addition, the Company may, to the extent permitted by law, and directly or indirectly
      (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or through its Subsidiaries or 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 Trustee for cancellation in accordance with Section 2.07, and they will no longer be considered “outstanding”
      under the Indenture upon their cancellation. 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 Trustee for cancellation in accordance with Section 2.07 and will continue to be considered “outstanding” for purposes of the Indenture, subject to the provisions of Section 8.02.

     

    ARTICLE 3

    Satisfaction and Discharge

     

    Section 3.01.  Applicability of Article 12 of the Base Indenture. Article 12 of the Base Indenture shall not apply to the Notes. Instead
      the provisions set forth in this Article 3 shall, with respect to the Notes, supersede in their entirety Article 12 of the Base Indenture, and all references in the Base Indenture to Article 12 thereof and the provisions therein, as the case may be,
      shall, with respect to the Notes, be deemed to be references to this Article 3 or the applicable provisions set forth in this Article 3, respectively.

     

    Section 3.02.  Satisfaction and Discharge. The Indenture shall upon request of the Company contained in an Officer’s Certificate cease
      to be of further effect, and the Trustee, at the expense of the Company, shall execute instruments acknowledging satisfaction and discharge of the Indenture as reasonably requested by the Company, when (a) (i) all Notes theretofore authenticated and
      delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee
      or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Redemption Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash, ADSs or a combination thereof, as
      applicable, solely to satisfy the Company’s Conversion Obligation, sufficient, without consideration of reinvestment, to pay all of the outstanding Notes and all other sums due and payable under the Indenture by the Company; and (b) 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 the Indenture have been complied with. Notwithstanding the
      satisfaction and discharge of the Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Base Indenture shall survive.

    ARTICLE 4

    Particular Covenants of the Company

     

    Section 4.01.  Maintenance of Office or Agency. Section 6.02 of the Base Indenture shall be superseded by this Section 4.01, and any
      reference in the Base Indenture to Section 6.02 shall be deemed to refer instead to this Section 4.01. The Company will maintain in the contiguous United States of America, an office or agency (which will be the Corporate Trust Office initially)
      where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”)






      and where notices in respect of the Notes and this Supplemental Indenture may be made. 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 at the Corporate Trust Office.

     

    The Company may also from time to time designate as co-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 contiguous United States of America for such
      purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

     

    The Company hereby initially designates the Trustee as the Paying Agent (other than for purposes of Article 15), Custodian, Registrar and Conversion Agent and the Corporate Trust Office shall be considered as one such
      office or agency of the Company for each of the aforesaid purposes; provided that no office of the Trustee shall be a place for service of legal process on the Company. For purposes of Article 15, the Paying
      Agent shall be the Trustee or other paying agent designated by the Company.

     

    Section 4.02.  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 11.06 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder.

     

    Section 4.03.  Provisions as to Paying Agent. Section 6.03 of the Base Indenture shall be superseded by this Section 4.03, and any
      reference in the Base Indenture to Section 6.03 shall be deemed to refer instead to this Section 4.03.

     

    
      21

      
        


    

    (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 4.03:

     

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

     

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

     

    (iii)         that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held.

     

    The Company shall, on or before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with
      the Paying Agent a sum in immediately available funds sufficient to pay such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest and (unless such Paying Agent is the
      Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on the
      relevant due date.

     

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

     

    (c)          Anything in this Section 4.03 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Supplemental 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 4.03, 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. Upon the occurrence of any event specified in  Section
      6.02(i) or Section 6.02(j), the Trustee shall automatically become the Paying Agent.

     

    
      22

      
        


    

    (d)          Subject to applicable escheatment laws, any money or property deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of principal (including the Redemption
      Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, or in satisfaction of its Conversion Obligation with respect to, any Note and remaining unclaimed for two years after such principal (including
      the Redemption Price and the Fundamental Change Repurchase Price, if applicable) or interest has become due and payable, or such Conversion Obligation became due, shall be paid or delivered, as the case may be, to the Company on request of the
      Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust and the Trustee shall have no further liability with respect to such funds; and the Holder of such Note shall thereafter, as an
      unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such money or property, and all liability of the Company as trustee thereof, shall thereupon cease.

     

    Section 4.04.  Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in
      full force and effect its corporate existence.

     

    Section 4.05.  Additional Amounts. Section 6.05 of the Base Indenture shall be superseded by this Section 4.05, and any reference in the
      Base Indenture to Section 6.05 shall be deemed to refer instead to this Section 4.05.

     

    (a)          All payments and deliveries made by, or on behalf of, the Company or any successor to the Company under or with respect to the Indenture and the Notes, including payments of principal (including, if
      applicable, the Redemption Price and the Fundamental Change Repurchase Price), payments of interest and payments of cash and/or deliveries of ADSs (together with payments of cash for any fractional ADS) upon conversion of the Notes, will be made
      without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or within any jurisdiction in which the Company or any successor to the Company
      is, for tax purposes, organized or resident or doing business (each, as applicable, a “Relevant Taxing Jurisdiction”) or through which payment is made or deemed made (together with each Relevant Taxing
      Jurisdiction, a “Relevant Jurisdiction,” and in each case, any political subdivision or taxing authority thereof or therein), unless such withholding or deduction is required by law or by regulation or
      governmental policy having the force of law. In the event that any such withholding or deduction is so required, the Company or any successor to the Company shall pay to each Holder such additional amounts (“Additional






        Amounts”) as may be necessary to ensure that the net amount received by the Holders after such withholding or deduction (and after deducting any taxes on the Additional Amounts) will equal the amounts that would have been received by such
      Holders had no such withholding or deduction been required; provided that no Additional Amounts will be payable:

     

    (i)           for or on account of:

     

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

     

    
      23

      
        


    

    (1)          the existence of any present or former connection between the Holder or beneficial owner of such Note and the Relevant Jurisdiction, other than merely holding such Note or the receipt of
      payments thereunder, including such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or
      business therein or having or having had a permanent establishment therein;

     

    (2)          the presentation of such Note (in cases in which presentation is required) more than 30 days after the later of the date on which the payment of the principal of (including the Redemption
      Price and the Fundamental Change Repurchase Price, if applicable) and interest on such Note or the payment of cash and/or the delivery of ADSs (together with payment of cash for any fractional ADS) upon conversion of such Note became due and payable
      pursuant to the terms thereof or was made or duly provided for;

     

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

     

    (4)          the presentation of such Note (in cases in which presentation is required) for payment in the Relevant Jurisdiction, unless such Note could not have been presented for payment elsewhere;

     

    (B)          any estate, inheritance, gift, sale, transfer, excise, personal property or similar tax, assessment or other governmental charge;

     

    (C)          any tax, duty, assessment or other governmental charge that is payable otherwise than by withholding from payments or deliveries under or with respect to the Notes;

     

    (D)          any tax, assessment, withholding or deduction required by sections 1471 through 1474 of the Code (“FATCA”), any current or future Treasury
      regulations or rulings promulgated thereunder, any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA, any intergovernmental agreement between the United States and any other jurisdiction to implement FATCA or
      any law enacted by such other jurisdiction 

     

    

    
      24

      
        


    

    to give effect to such agreement, or any agreement with the U.S. Internal Revenue Service under FATCA; or

     

    (E)          any combination of taxes, duties, assessments or other governmental charges referred to in the preceding clauses (A), (B), (C) or (D); or

     

    (ii)          with respect to any payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) and interest on such Note or the payment of
      cash and/or the delivery of ADSs (together with payment of cash for any fractional ADS) upon conversion of such Note to a Holder, if the Holder is a fiduciary, partnership or person other than the sole beneficial owner of that payment to the extent
      that such payment would be required to be included in the income under the laws of the Relevant Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a partner or member of that partnership or a beneficial owner
      who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner, member or beneficial owner been the Holder thereof.

     

    (b)          The Trustee and the Paying Agent shall also be entitled to make any withholding or deduction pursuant to an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to FATCA and any
      regulations or agreements thereunder or official interpretations thereof.

     

    (c)          Any reference in the Indenture or the Notes in any context to the payment of cash and/or the delivery of ADSs (together with payments of cash for any fractional ADS), as applicable, upon conversion of any
      Note or the payment of principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) and interest on any Note or any other amount payable with respect to such Note, shall be deemed to include payment of
      Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable with respect to that amount pursuant to this Section 4.05.

     

    (d)          If the Company or its successor is required to make any deduction or withholding from any payments or deliveries with respect to the Notes, it will deliver to the Trustee and the Holders official tax
      receipts evidencing the remittance to the relevant tax authorities of the amounts so withheld or deducted.

     

    (e)          The Trustee shall have no obligation to determine whether any Additional Amounts are payable under the Indenture or the amount thereof.

     

    (f)          The foregoing obligations shall survive termination or discharge of the Indenture.

     

    Section 4.06.  Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any
      time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on
      the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of the 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.

      under the Indenture and the Company has fulfilled its obligations thereunder, and whether such Officer thereof have knowledge of any Default by the Company that occurred during the previous year that is then continuing and, if so, specifying each
      such Default and the nature thereof.

      Instead, the provisions set forth in this Article 6 shall, with respect to the Notes, supersede in its entirety Article VII of the Base Indenture, and all references in the Base Indenture to Article VII thereof and the provisions therein, as the case
      may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the applicable provisions set forth in this Article 6, respectively.

     

    Section 6.02.  Events of Default. Each of the following events shall be an “Event of Default”
      with respect to the Notes:

     

    (a)          default in any payment of interest or Additional Amounts, if any, on any Note when due and payable and the default continues for a period of 30 days;

     

    
      26

      
        


    

    (b)          default in the payment of principal of any Note when due and payable on the Maturity Date, upon Optional Redemption, upon any required repurchase, upon declaration of acceleration or otherwise;

     

    (c)          failure by the Company to comply with its obligation to convert the Notes in accordance with the Indenture upon exercise of a Holder’s conversion right and such failure continues for a period of five
      Business Days;

     

    (d)          failure by the Company to issue a Fundamental Change Company Notice in accordance with Section 15.02(c), notice of a Make-Whole Fundamental Change in accordance with Section 14.03(a) or notice of a specified
      corporate event in accordance with Section 14.01(b)(ii) or 14.01(b)(iii), in each case, when due and such failure continues for a period of five Business Days;

     

    (e)          failure by the Company to comply with its obligations under Article 11;

     

    (f)          failure by the Company for 60 days after written notice from the Trustee or by the Trustee at the request of the Holders of at least 25% in aggregate principal amount of the Notes then outstanding has been
      received by the Company to comply with any of its other agreements contained in the Notes or the Indenture;

     

    (g)          default by the Company or any Significant Subsidiary of the Company with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or
      evidenced, any indebtedness for money borrowed in excess of US$200 million (or the foreign currency equivalent thereof) in the aggregate by the Company and/or any such Significant Subsidiary, whether such indebtedness now exists or shall hereafter be
      created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity or (ii) constituting a failure to pay the principal or interest of any such indebtedness when due and payable at its stated maturity,
      upon required repurchase, upon declaration of acceleration or otherwise and in each case, such indebtedness is not discharged, or such acceleration is not otherwise cured or rescinded, within 30 days (in the case of clause (ii) of this Section
      6.02(g), within the greater of (x) 30 days or (y) the expiration of any grace period or extension of time for payment applicable thereto);

     

    (h)          [Reserved].

     

    (i)          the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant
      Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant
      Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general
      assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or

     

    (j)          an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the Company or such
      Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant
      Subsidiary or

    

     

    

    
      27

      
        


    

     any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive days.

      

    

    For the avoidance of doubt, for purposes of Section 6.02(g), “indebtedness for money borrowed” shall not include any obligations due under any foreign exchange, currency option, currency swap or other similar
      transaction.

     

    Section 6.03.  Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever
      the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental
      body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of the Notes shall have
      already become due and payable, the Trustee may by notice in writing to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.02, by notice in writing to the
      Company and to the Trustee may, and the Trustee at the request of such Holders accompanied by security and/or indemnity satisfactory to the Trustee and otherwise subject to the limitations set forth in the Indenture, shall, declare 100% of the
      principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, notwithstanding anything contained in the
      Indenture or in the Notes to the contrary. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and
      unpaid interest on, all Notes shall become and shall automatically be immediately due and payable without any action on the part of the Trustee. If an Event of Default occurs and is continuing, all agents of the Company appointed under the Indenture
      will be required to act on the direction of the Trustee.

     

    The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the
      payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum in immediately available funds sufficient to pay installments of accrued and unpaid interest upon all
      Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable
      law, and on such principal at the rate per annum borne by the Notes) and amounts due to the Trustee pursuant to Section 11.01 of the Base Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent
      jurisdiction and (2) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest on Notes that shall have become due solely by such acceleration, shall have been cured
      pursuant to Section 6.02 or waived pursuant to Section 6.10, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written
      notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind any such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom

     

    

    
      28

      
        


    

    shall be deemed to have been cured for every purpose of the Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent
      thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest
      on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

     

      

    Section 6.04.  Additional Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Company
      elects, the sole remedy for Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company is required to file with the SEC pursuant
      to Section 13 or 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in Section 10.02 of the Base Indenture shall after the occurrence of such an Event of Default (which will be the 60th day after
      written notice is provided to the Company pursuant to Section 6.02(f)) consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to:

     

    (a)          0.25% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such an Event of Default first occurs and ending on the earlier
      of (i) the date on which such Event of Default is cured or validly waived and (ii) the 180th 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 181st 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 181st 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 360th day
      immediately following, and including, the date on which such Event of Default first occurred.

     

    If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 366th day after such Event of Default (if the Event of Default with
      respect to the Company’s failure to file is not cured or waived prior to such 366th day), the Notes shall be immediately subject to acceleration as provided in Section 6.03. In the event the Company does not elect to pay the Additional Interest
      following an Event of Default in accordance with this Section 6.04 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.03.

     

    In order to elect to pay Additional 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 Company’s failure to timely give such written notice, the Notes shall be immediately subject to acceleration as
      provided in Section 6.03. 

     

    

    
      29

      
        


    

    Section 6.05.  Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.02 shall
      have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue
      principal and interest, if any, at the rate per annum borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 11.01 of the Base Indenture. If the
      Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to
      judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor
      upon the Notes, wherever situated.

     

    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 6.05, shall be entitled and empowered, by
      intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of
      claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, 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 11.01 of the Base Indenture; 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 reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 11.01 of the Base Indenture,
      incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and 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 

     

    

    
      30

      
        


    

    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 the Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other
      proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable
      compensation, expenses, 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 the 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 the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.10 or any rescission and
      annulment pursuant to Section 6.03 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 6.06.  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 the Trustee under Section 11.01 of the Base Indenture and any payments due to the Paying Agent, the Conversion Agent and the Registrar;

     

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

     

    
      31

      
        


    

    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 or the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the
      extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate per annum borne by the Notes at such time, 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 or the Fundamental Change Repurchase Price and any cash due upon conversion) and interest without preference or priority of principal over interest,
      or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Redemption Price or the Fundamental
      Change Repurchase Price) and accrued and unpaid interest; and

     

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

     

    Section 6.07.  Proceedings by Holders

     

    . Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price or the Fundamental Change Repurchase Price) or interest when due, or the right to receive
      payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or
      with respect to the 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 (and if requested, provided) to the Trustee such security and/or indemnity satisfactory to the Trustee against any loss, liability or expense to be incurred therein or
      thereby;

     

    (d)          the Trustee for 60 days after its receipt of such notice, request and offer of security and/or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and

     

    (e)          no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes
      then outstanding within such 60-day period pursuant to Section 6.10,

     

    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 the Indenture to affect, disturb or prejudice the rights of any other Holder, (it being further understood that the Trustee shall not have an affirmative duty to ascertain whether or not any such direction is unduly
      prejudicial to 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 the Indenture, except 

    

     

    

    
      32

      
        


    

     in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.07, 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 the 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 and the
      Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the 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 6.08.  Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce
      the rights vested in it by the 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 the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law. The
      Trustee may maintain a proceeding even if it does not possess any Notes or does not produce any Notes in the proceeding.

     

    Section 6.09.  Remedies Cumulative and Continuing. Except as provided in Section 3.07(e) of the Base Indenture, 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 the 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 6.07, 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 6.10.  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 8.02 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
      Supplemental Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of
      any other Holder or that would involve the Trustee in personal liability (it being understood that the Trustee shall not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial to any other Holder), or if it is
      not provided with 

    

     

    

    
      33

      
        


    

    security and/or indemnity to its satisfaction against loss, liability or expense. 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 8.02 may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and
      unpaid interest on, or the principal (including, if applicable, the Redemption Price or the Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (ii) a failure by the Company
      to pay or deliver, or cause to be delivered, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the
      consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or
      other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.10, said Default or Event of Default shall for all purposes of the
      Notes and the 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 6.11.  Notice of Defaults and Events of Default. Section 11.03 of the Base Indenture shall be superseded by this Section 6.11,
      and any reference in the Base Indenture to Section 11.03 shall be deemed to refer instead to this Section 6.11. If a Default or Event of Default occurs and is continuing and is notified in writing to a Responsible Officer of the Trustee, the Trustee
      shall, within 90 days after the Responsible Officer of the Trustee receives such written notice or obtains such knowledge, send to all Holders (at the Company’s expense) as the names and addresses of such Holders appear upon the Register, notice of
      all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that the Trustee shall not be deemed to have knowledge of any
      occurrence of a Default or an Event of Default unless a Responsible Officer of the Trustee has received written notice of such Default or Event of Default describing the circumstances of such, and identifying the circumstances constituting such
      Default or Event of Default and stating that such notification is a “notice of default.” Except in the case of a Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable),
      or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee (in its sole discretion) in
      good faith determines that the withholding of such notice is in the interests of the Holders.

     

    Section 6.12.  Undertaking to Pay Costs. All parties to the 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 the 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 reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due
      regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.12 (to the extent permitted by law) shall not apply to any suit
      instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.02, or to any

    suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest on any Note (including, but not limited to, the Redemption Price and the Fundamental Change Repurchase Price with respect to the
      Notes being repurchased as provided in this Supplemental 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.

    Concerning the Trustee

     

    Section 7.01.  Monies and ADSs to Be Held in Trust. Section 11.01(g) of the Base Indenture shall be superseded by this Section 7.01, and
      any reference in the Base Indenture to Section 8.03 shall be deemed to refer instead to this Section 7.01. All monies and ADSs 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 and ADSs held by the Trustee in trust or by the Paying 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 shall be under any
      liability for interest on any money or ADSs received by it hereunder.

     

    Section 7.02.  Compensation and Expenses of Paying Agent, Conversion Agent and Registrar. The Paying Agent, the Conversion Agent and the
      Registrar shall be entitled to the compensation to be agreed upon in writing with the Company for all services rendered by it under the Indenture, and the Company agrees promptly to pay such compensation and to reimburse the Paying Agent, the
      Conversion Agent and the Registrar for its out-of-pocket expenses (including reasonable fees and expenses of counsel) incurred by it in connection with the services rendered by it under the Indenture. The Company hereby agrees to indemnify the Paying
      Agent, the Conversion Agent and the Registrar and their respective officers, directors, agents and employees and any successors thereto for, and to hold it harmless against, any loss, liability or expense (including reasonable fees and expenses of
      counsel) incurred without gross negligence or willful misconduct on its part, as determined by a final, non-appealable decision of a court of competent jurisdiction, arising out of or in connection with its acting as the Paying Agent, the Conversion
      Agent and the Registrar hereunder. The obligations of the Company under this paragraph shall survive the payment of the Notes, the termination of the Indenture and the resignation or removal of the Paying Agent, the Conversion Agent and the
      Registrar.

     

    ARTICLE 8

    Concerning the Holders

     

    Section 8.01.  Who Are Deemed Absolute Owners. Section 8.03 of the Base Indenture shall be superseded by this Section 8.01, and any
      reference in the Base Indenture to Section 8.03 shall be deemed to refer instead to this Section 8.01 The Company, the Trustee, any Paying Agent, any Conversion Agent and any Registrar shall deem the Person in whose name a Note shall be registered
      upon the Register to be, and shall treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or 

    

     

    

    
      35

      
        


    

    other writing thereon made by any Person other than the Company or any Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.04) accrued and unpaid interest on such Note, for the
      purpose of conversion of such Note and for all other purposes under the Indenture; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Registrar shall be affected by any notice to the contrary.  The sole
      registered holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or ADSs so paid or delivered,
      effectual to satisfy and discharge the liability for monies payable or ADSs deliverable upon any such Note. Notwithstanding anything to the contrary in the Indenture or the Notes following an Event of Default, any owner of a beneficial interest in a
      Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such owner’s right to exchange such beneficial interest for a Note in
      certificated form in accordance with the provisions of the Indenture.

     

      

    Section 8.02.  Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes
      have concurred in any direction, consent, waiver or other action under this Supplemental Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Affiliate of the Company or any Subsidiary thereof shall be disregarded and
      deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver
      or other action only Notes in respect of which a Responsible Officer is notified in writing shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.02 if the
      pledgee shall establish its right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. Within five days of acquisition of the Notes by any of the
      above described persons or entities, the Company shall furnish to the Trustee promptly an 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 11.02 of the Base Indenture, the Trustee shall be entitled 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.

     

    Section 8.03.  Revocation of Consents. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01 of
      the Base Indenture, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Supplemental 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 of the Base Indenture, revoke
      such action so far as concerns such Note.

    (m)         to comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act.

     

    Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may
      be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties, liabilities or immunities under the Indenture or otherwise.

     

    Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding
      any of the provisions of Section 10.02.

     

    Section 10.02.  Supplemental Indentures with Consent of Holders. Section 14.02(a) of the Base Indenture shall be superseded by this
      Section 10.02, and any reference in the Base Indenture to Section 14.02(a) shall be deemed to refer instead to this Section 10.02. With the consent (evidenced as provided in Article VIII of the Base Indenture, as amended and supplemented by Article 8
      of this Supplemental Indenture) of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article VIII of the Base Indenture, as amended and supplemented by Article 8 of this
      Supplemental Indenture 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 the Indenture or any
      supplemental indenture or of 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;

     

    (b)          reduce the rate of or extend the stated time for payment of interest on any Note;

     

    (c)          reduce the principal of or extend the Maturity Date of any Note;

    Section 11.01.  Company May Consolidate, Etc. on Certain Terms. Section 6.04 of the Base Indenture shall be superseded by this Article
      11, and any reference in the Base Indenture to Section 6.04 shall be deemed to refer instead to this Article 11. Subject to the provisions of Section 11.02, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or
      lease all or substantially all of its properties and assets to another Person, unless:

     

    (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 of America, any State thereof, the District of Columbia, the Cayman Islands, the British Virgin Islands, Bermuda, Singapore 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 the Indenture (including, for the avoidance of doubt, the obligation to pay Additional Amounts pursuant to Section 4.05); and

     

    (b)          immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under the Indenture.

     

    For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and
      assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or
      substantially all of the properties and assets of the Company to another Person.

     

    Section 11.02.  Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease
      and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes (including, for the avoidance
      of doubt, any Additional Amounts), the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes (including, for the avoidance of doubt, any Additional Amounts) and the due and punctual
      performance of all of the covenants and conditions of the Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the 

     

    

    
      39

      
        


    

    case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may
      cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such
      Successor Company instead of the Company and subject to all the terms, conditions and limitations in the 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 any Officer 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 the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the 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 Supplemental 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 the 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. No consolidation, merger, sale, conveyance, transfer or lease shall be
      effective unless the Trustee shall receive 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.

      40

      
        


    

    (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 June 15, 2026
      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 June 15, 2026 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 2.0964 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”).

     

    (b)          (i) Prior to the close of business on the Business Day immediately preceding June 15, 2026, 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 written 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 Supplemental Indenture. The Company shall provide written notice to the Bid
      Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. 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 aggregate 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. 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

     

    

    
      41

      
        


    

     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), and thereafter neither the Company nor the Bid Solicitation Agent (of other than the Company) shall be required to solicit bids again until a new Holder request is
      made as provided in this Section 14.01.

     

    (ii)          If, prior to the close of business on the Business Day immediately preceding June 15, 2026, the Company elects to:

     

    (A)         issue to all or substantially all holders of the Class A Ordinary Shares (directly or in the form of ADSs) any rights, options or warrants entitling them, for a period of not more than 45
      calendar days after the announcement date of such issuance, to subscribe for or purchase Class A 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, 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 Class A 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 the Last Reported Sale Price of the ADSs on the Trading Day preceding the date of announcement for such distribution,

     

    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 44 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or
      distribution; provided that if the Company elects Physical Settlement for conversions that occur during the Distribution Conversion Period the Company may provide not less than 10 Business Days’ nor more
      than 30 Business Days’ notice before such Ex-Dividend Date. Once the Company has given such notice, a Holder may surrender all or any portion of its Notes for conversion at any time from, and including, the date the Company provides such notice until
      the earlier of (1) the close of business on the second 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 (such period,
      the “Distribution Conversion Period”), in each case, even if the Notes are not otherwise convertible at such time.

     

    (iii)         If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding June 15,
      2026, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or 

     

    

    
      42

      
        


    

    lease of all or substantially all of its assets that occurs prior to the close of business on the Business Day immediately preceding June 15, 2026, 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 Business Days after the actual effective date of such transaction
      or, if such transaction also constitutes a Fundamental Change (other than an Exempted 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.

     

    (iv)         Prior to the close of business on the Business Day immediately preceding June 15, 2026, 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 December 31, 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.

     

    (v)          If the Company calls any Notes for an Optional Redemption, a Cleanup Redemption, or a Tax Redemption pursuant to Article 16 prior to the close of
      business on the Business Day immediately preceding June 15, 2026, then a Holder may surrender for conversion all or any portion of such Notes called for redemption at any time during the related Redemption Period, even if the Notes are not otherwise
      convertible at such time.  After that time, the right to convert shall expire under this clause (v), unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert all or any portion of such Notes
      called for redemption 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 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 related Redemption Date, and
      all conversions for which the relevant Conversion Date occurs on or after June 15, 2026 shall be settled using the same Settlement Method.

     

    
      43

      
        


    

    (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 related Redemption
      Date, and any conversions for which the relevant Conversion Date occurs on or after June 15, 2026, 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 the period described in the third immediately succeeding set of parentheses, 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 Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs during the
      related Redemption Period, in such Redemption Notice or on or after June 15, 2026, no later than June 15, 2026). 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 Cash Settlement or Physical Settlement for such conversion or during such period and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified
      Dollar Amount per US$1,000 principal amount of Notes shall be equal to US$1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall
      indicate the Specified Dollar Amount per US$1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per
      US$1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per US$1,000 principal amount of Notes shall be deemed to be US$1,000. By written notice to the Holders, the Trustee and the Conversion Agent, the Company may,
      prior to June 15, 2026, irrevocably elect a Settlement Method and/or a Specified Dollar Amount (or minimum Specified Dollar Amount), or eliminate the Company’s right to elect a Settlement Method, to apply all conversions for which the relevant
      Conversion Date occurs subsequent to the date of delivery of such notice; provided that any such election that is made during a Redemption Period or a Distribution Conversion Period shall not apply to any
      conversions of Notes called for redemption with Conversion Dates that occur during such Redemption Period or conversions during such Distribution Conversion Period (as applicable).

     

    (iv)         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 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 

     

    

    
      44

      
        


    

    being converted a number of ADSs equal to the Conversion Rate in effect immediately after the close of business on the relevant Conversion Date;

     

    (B)          if the Company elects 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.

     

    (v)          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, comply with the procedures of the
      Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h), and if required, pay all transfer or similar taxes, if
      any and (ii) in the case of a Physical Note (1) complete, manually sign and deliver a duly completed irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile, PDF or other electronic transmission
      thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder
      wishes the certificate or certificates for any ADSs to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and
      transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is
      not entitled as set forth in Section 14.02(h), and if required, pay all transfer or similar taxes, if any. 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 for conversion, by a Holder thereof if such Holder has also delivered a Fundamental

      

    

    
      45

      
        


    

    Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03.

     

    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.

     

    (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 or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business
      Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of any other Settlement Method;
      provided that, with respect to any Conversion Date occurring during a Redemption Period, the Company shall settle any such conversion for which Physical Settlement is applicable on the relevant Redemption
      Date; provided further that, notwithstanding the foregoing, with respect to any Conversion Date occurring after the Regular Record Date immediately preceding the Maturity Date, the Company shall settle any
      such conversion for which Physical Settlement is applicable on the Maturity Date. 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 certificated Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so
      surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or
      Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or 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 Class A Ordinary Shares, unless the tax is due because the Holder requests such ADSs (or the Class A 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 shall be
      responsible for the ADS Depositary’s fees for the issuance of the ADSs.

     

    (f)           Except as provided in Section 14.04, no adjustment shall be made for dividends on any ADSs issued upon the conversion of any Note as provided in this Article 14.

     

    
      46

      
        


    

    (g)          Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount
      represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

     

    (h)          Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be
      deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including,
      the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and ADSs, accrued and unpaid interest 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 Regular Record Date and prior to the open of business on the corresponding Interest Payment Date, Holders of such Notes as of the
      close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. However, Notes surrendered for conversion during the period from
      the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by an amount in U.S. dollars equal to the amount of interest payable on the Notes so converted (regardless
      of whether the converting Holder was the holder of record on the corresponding Regular Record Date); provided that no such payment shall be required (1) for conversions following the Regular Record Date
      immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the second Business Day immediately succeeding the corresponding Interest Payment Date (or, if such
      Interest Payment Date is not a Business Day, the third Business Day immediately succeeding such Interest Payment Date); (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the
      Business Day immediately succeeding the corresponding Interest Payment Date (or, if such Interest Payment Date is not a Business Day, the second Business Day immediately succeeding such Interest Payment Date); or (4) to the extent of any Defaulted
      Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, the Holder of the Notes on the Regular Record Date immediately preceding the Maturity Date, any Fundamental Change
      Repurchase Date or Redemption Date, in each case, will receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date in cash, regardless of whether their Notes have been converted following such Regular Record
      Date. Neither the Trustee nor the Conversion Agent (if other than the Trustee) will have any duty to determine or verify determination by the Company of whether any of the conditions to conversion have been satisfied.

     

    (i)           The Person in whose name any ADSs shall be issuable upon conversion shall become the holder of record of such ADSs only as of the close of business on the date the ADS Depositary registers such ADSs upon
      issuance; provided, however, that the Company shall endeavor to treat such Person as the holder of record of such ADSs for purposes of dividends and distributions in respect 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

     

    

    
      47

      
        


    

     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 ADSs upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional ADS issuable 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 shares remaining after such computation shall be paid in cash.

     

    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 or
      that constitutes an Exempted Fundamental Change, the 35th Business Day immediately following the Effective Date of such Make-Whole Fundamental Change). The Company shall provide written notification to Holders, the Trustee and the Conversion Agent
      (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change and publish a notice on the Company’s website or through such other public medium as the Company may use at that time announcing such Effective Date no later than
      five Business Days after such Effective Date.

     

    (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 following the Effective Date of such Make-Whole Fundamental Change, the
      Conversion Obligation shall be calculated based solely on the ADS Price for the transaction and shall be deemed to be an amount of cash per US$1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for
      Additional ADSs), multiplied by such ADS Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the third Business Day following the Conversion Date.

     

    
      48

      
        


    

    (c)          The number of Additional ADSs, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs
      or becomes effective (the “Effective Date”) and the price (the “ADS Price”) paid (or deemed to be paid) per ADS in the Make-Whole Fundamental Change. If the holders of
      the ADSs receive in exchange for their ADSs only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the ADS Price shall be the cash amount paid per ADS. Otherwise, the ADS Price shall be the
      average of the Last Reported Sale Prices of the ADSs over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

     

    (d)          The ADS Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted ADS Prices shall equal the
      ADS Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the ADS Price adjustment
      and the denominator of which is the Conversion Rate as so adjusted. The number of Additional ADSs set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 14.04.

     

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

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

     

    (i)           if the ADS Price is between two ADS Prices in the table above or the Effective Date is between two Effective Dates in the table, the number of Additional ADSs shall be determined by a
      straight-line interpolation between the number of Additional ADSs set forth for the higher and lower ADS Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

     

    (ii)          if the ADS Price is greater than US$2,000 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$318 per ADS (subject to adjustment in the same manner as the ADS Prices set forth in the column headings of the table above 

    
      49

      
        


    

    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 3.1446 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 called for redemption in connection with an Optional Redemption, a Cleanup Redemption or a Tax Redemption pursuant to Article 16, the Conversion Rate shall be
      increased by a number of Additional ADSs determined pursuant to this Section 14.03(g). The Company shall settle conversions of Notes as described in Section 14.02 and, for the avoidance of doubt, pay Additional Amounts, if any, with respect to any
      such conversion.

     

    A conversion of Notes called for redemption shall be deemed to be “in connection with” an Optional Redemption, a Cleanup Redemption or a Tax Redemption, if the relevant Notice of Conversion is received by the Conversion
      Agent during the relevant Redemption Period. In the event that a conversion of the Notes called for redemption in connection with an Optional Redemption, a Cleanup Redemption or a Tax Redemption pursuant to Article
        16 would also be deemed to be in connection with a Make-Whole Fundamental Change, a Holder of the Notes to be converted shall be entitled to a single increase to the Conversion Rate with respect to the first to occur of the applicable
      Redemption Notice or the Effective Date of the applicable Make-Whole Fundamental Change, and the later event shall be deemed not to have occurred for purposes of this Section 14.03(g) and the adjustments described under Section 14.03(a). For the
      avoidance of doubt, if the Company issues a Redemption Notice as set forth under Article 16, the Company shall increase the Conversion Rate hereunder during the related Redemption Period only with respect to conversions of Notes called for redemption
      (or deemed to be called for redemption). Accordingly, if the Company elects fewer than all of the outstanding Notes as described under Article 16, Holders will not be entitled to convert the Notes that are neither called for redemption nor deemed to
      be called for redemption on account of the Redemption Notice and will not be entitled to an increased Conversion Rate for conversions of such Notes on account of the Redemption Notice during the related Redemption Period, even if such Notes are
      otherwise convertible.

     

    The number of Additional ADSs by which the Conversion Rate will be increased in the event of conversions of Notes called for redemption in connection with an Optional Redemption, a Cleanup Redemption or a Tax Redemption
      pursuant to Article 16 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 called for redemption in connection with a Make-Whole Fundamental Change, (y) the applicable “Redemption Reference Date” were the “Effective Date” as specified in
      clause (c) above and (z) the applicable “Redemption Reference Price” were the “ADS Price” as specified in clause (c) above. For this purpose, the date on which the Company delivers a Redemption Notice is the “Redemption






      

     

      

    
      50

      
        


    

    Reference Date” and the average of the Last Reported Sale Prices of the ADSs over the five Trading Day immediately preceding, the date the Company delivers such Redemption Notice is the “Redemption Reference Price.”

     

    Section 14.04.  Adjustment of Conversion Rate. If the number of Class A Ordinary Shares represented by the ADSs is changed, after the
      date of this Supplemental 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 Class A 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 Class A 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 Class A
      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 Class A Ordinary Shares. However, in the event that the Company issues or distributes to all holders of the Class A 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 Class A Ordinary Shares for a period of not more than 45 calendar days after the announcement date of such
      issuance to subscribe for or purchase Class A 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 Class A 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 to which 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 a (x) share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the ADSs and solely as a result of holding the Notes, in any of the transactions
      described in this Section 14.04, without having to convert their Notes, as if they held a number of ADSs equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held
      by such Holder. Neither the Trustee nor the Conversion Agent shall have any responsibility to monitor the accuracy of any calculation of adjustment of the Conversion Rate and the same shall be conclusive and binding on the Holders, absent manifest
      error.

     

    
      51

      
        


    

    (a)          If the Company exclusively issues Class A Ordinary Shares as a dividend or distribution on the Class A Ordinary Shares, or if the Company effects a share split or share combination, the Conversion Rate shall
      be adjusted based on the following formula:

     

    

     

    where,

     

    
      
        	CR0	=          	the Conversion Rate in effect immediately prior to the 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 after the open of business on such Ex-Dividend Date or Effective Date, as applicable;


      

    

     

    
      
        	OS0	=          	the number of Class A Ordinary Shares issued and 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 Class A Ordinary Shares issued and 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 Class A 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 45 calendar days after the announcement date of such issuance, to subscribe for or purchase Class A 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 Class A Ordinary Shares or the ADSs, as the case may be (divided by, in the case of the ADSs, the number of Class A 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:

     

    

     

    
      52

      
        


    

    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 Class A Ordinary Shares issued and outstanding immediately prior to the open of business on such Ex-Dividend Date;


      

    

     

    
      
        	X          	=          	the total number of Class A Ordinary Shares (directly or in the form of ADSs) deliverable pursuant to such rights, options or warrants; and


      

    

     

    
      
        	Y          	=          	the number of Class A 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 Class A Ordinary Shares then represented by one ADS.


      

    

     

    Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for the ADSs for such
      issuance. To the extent that Class A 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 Class A 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 adjustment been made on the basis of only the issuance, if any, actually made.

     

    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 Class A 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 Class A Ordinary Shares or the ADSs, as the case may be (divided by, in the case of the ADSs, the
      number of Class A 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 Class A 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 Class A Ordinary Shares (directly or in 

     

    

    
      53

      
        


    

    the form of ADSs), excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was
      effected pursuant to Section 14.04(d), and (iii) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or
      warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

     

    

     

    where,

     

    
      
        	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date 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 Class A 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 Class A 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 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. To the extent such distribution is not so paid or made,
      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 made or paid. 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 Class A 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:

     

    
      54

      
        


    

    

     

    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 Class A Ordinary Shares (directly or in the form of ADSs) applicable to
                one Class A 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 Class A Ordinary Shares then represented by one ADS) over the Valuation
                Period.


      

    

     

    The increase to the Conversion Rate under the preceding paragraph shall occur at 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 to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have
      elapsed between the Ex-Dividend Date of such Spin-Off and the 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, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the
      Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. If the dividend or other distribution constituting the Spin-Off is not so paid or made, the Conversion Rate shall be decreased,
      effective as of the date the Board of Directors determines not to make or pay such dividend or other distribution, to the Conversion Rate that would be in effect if such distribution had not been declared.

     

    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 Class A Ordinary Shares (directly or in the form of ADSs)
      entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Class A 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 Class A 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 Class A 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

     

    

    
      55

      
        


    

     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 Supplemental 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 Class A 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 Class A
      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 Class A 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 Class A 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 

     

    

    
      56

      
        


    

    “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 Class A Ordinary Shares (directly or in the form of ADSs), the Conversion Rate shall be adjusted based on the following
      formula:

     

    

     

    where,

     

    
      
        	CR0	=	the Conversion Rate in effect immediately prior to the 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 such Ex-Dividend Date;


      

    

     

    
      
        	SP0	=	the Last Reported Sale Price of the ADSs (divided by the number of Class A Ordinary Shares then represented by one ADS) on the Trading Day immediately
                preceding the Ex-Dividend Date for such dividend or distribution; and


      

    

     

    
      
        	C	=

              	the amount in cash per Class A Ordinary Share the Company distributes to all or substantially all holders of the Class A Ordinary Shares (directly or in the form of ADSs).


      

    

     

    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. To the extent 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 had the adjustment been made on the basis of only
      the dividend or distribution, if any, actually made or paid. 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 make a payment in respect of a tender or exchange offer for the Class A Ordinary Shares (directly or in the form of ADSs), to the extent that the cash and value of
      any other consideration included in the payment per Ordinary Share exceeds the average of the Last Reported Sale Prices of the ADSs (divided by the number of Class A 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:

     

    
      57

      
        


    

    

     

    where,

     

    
      
        	CR0	=	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or
                exchange offer expires;


      

    

     

    
      
        	CR1	=	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange
                offer expires;


      

    

     

    
      
        	AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for Class A Ordinary Shares or ADSs, as the case may be, purchased in such
                tender or exchange offer;


      

    

     

    
      
        	OS0	= 

              	the number of Class A Ordinary Shares issued and outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all Class A Ordinary
                Shares or ADSs, as the case may be, accepted for purchase or exchange in such tender or exchange offer);


      

    

     

    
      
        	OS1	=	the number of Class A Ordinary Shares issued and outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all Class A 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 Class A 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 increase to the Conversion Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (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 to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such
      tender or exchange offer expires and the 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 any tender or exchange offer, references to “10” or “10th” in the preceding
      paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the 

     

    

    
      58

      
        


    

    expiration date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day.

     

    To the extent such tender or exchange offer is announced but not consummated (including as a result of being precluded from consummating such tender or exchange offer under applicable law), or any purchases or exchanges
      of the Class A Ordinary Shares (directly or in the form of ADSs) in such tender or exchange offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of
      only the purchases or exchanges of the Class A Ordinary Shares (directly or in the form of ADSs), if any, actually made, and not rescinded, in such tender or exchange offer.

     

    (f)          Notwithstanding this Section 14.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and 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) based on an adjusted Conversion Rate for such
      Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. 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.

     

    (g)          Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of Class A Ordinary Shares or ADSs or any securities convertible into or exchangeable for Class A Ordinary Shares or
      ADSs or the right to purchase Class A 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 New York Stock
      Exchange 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 Class A Ordinary Shares or the ADSs or rights to
      purchase Class A Ordinary Shares or ADSs in connection with a dividend or distribution of Class A Ordinary Shares or ADSs (or rights to acquire Class A 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 Class A 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 Class A Ordinary Shares or ADSs under any plan;

     

    
      59

      
        


    

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

     

    (iii)         upon the repurchase of any Class A Ordinary Shares or ADSs 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 Class A 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 (other than any rights under a rights plan);

     

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

     

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

     

    (j)           All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of an ADS.

     

    (k)          If an adjustment to the Conversion Rate otherwise required by this Section 14.04 would result in a change of less than 1.00% to the Conversion Rate, then, notwithstanding the foregoing, the Company may, at
      its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to occur of the following: (i) when all such deferred adjustments would result in an aggregate change
      of at least 1.00% to the Conversion Rate, (ii) on the Conversion Date for any Notes (in the case of Physical Settlement), (iii) on each Trading Day of any Observation Period related to any conversion of Notes (in the case of Cash Settlement or
      Combination Settlement) and (iv) on the Effective Date of any Fundamental Change or any Make-Whole Fundamental Change, in each case, unless the adjustment has already been made. In addition, the Company shall not account for such deferrals when
      determining whether any of the conditions described in Section 14.01(b) have been satisfied or what number of ADSs a Holder would have held on a given day had it converted its Notes.

     

    (l)           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 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 a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall
      not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall

     

    

    
      60

      
        


    

     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 Register (with a copy to the Trustee). 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.

     

    (m)         For purposes of this Section 14.04, the number of Class A Ordinary Shares at any time outstanding shall not include Class A 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 Class A Ordinary Shares held in the treasury of the Company (directly or in the form of ADSs), but shall include Class A Ordinary Shares issuable in respect of scrip
      certificates issued in lieu of fractions of Class A Ordinary Shares.

     

    Section 14.05.  Adjustments of Prices. Whenever any provision of this Supplemental 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 an Optional Redemption, a Cleanup
      Redemption or a Tax Redemption pursuant to Article 16 over a span of multiple days, the Company shall make appropriate adjustments in good faith and in a commercially reasonable manner 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.  Class A Ordinary Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized
      but unissued Class A Ordinary Shares or Class A Ordinary Shares held in treasury, a sufficient number of Class A 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 Class A 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 Class A Ordinary Shares.

     

    (a)          In the case of:

     

    (i)           any recapitalization, reclassification or change of the ADSs or Class A Ordinary Shares (other than changes resulting from a subdivision or combination),

     

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

     

    
      61

      
        


    

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

     

    (iv)         any statutory share exchange,

     

    in each case, as a result of which the ADS or the Class A Ordinary Shares would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted
      under Section 10.01(f) providing that, at and after the effective time of such Merger Event, the right to convert each US$1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount
      of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of ADSs equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to
      receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one ADS is entitled to
      receive) upon such Merger Event; provided, however, that at and after the effective time of the Merger Event (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 Merger Event causes the ADSs or Class A 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 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. If the holders of the ADSs or Class A Ordinary Shares receive only cash in such Merger Event, then for all
      conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each US$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 by any Additional ADSs pursuant to Section 14.03), multiplied by the price paid per ADS or Class A Ordinary Share, as applicable, in such Merger
      Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant Conversion Date. 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.

     

    
      62

      
        


    

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

     

    (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 14.07 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 Class A 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 Class A 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 SEC, 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 Class A 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

    
      63

      
        


    

     number of ADSs available for issuance thereunder such that ADSs can be delivered in accordance with the terms of the Indenture, the Notes and the Deposit Agreement upon conversion of the Notes.

     

    Section 14.09.  Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or
      responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or
      calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with
      respect to the validity or value (or the kind or amount) of any ADSs, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no
      representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any ADSs or stock certificates or other securities or property or cash upon the
      surrender of any Note for the purpose of conversion, the accuracy or inaccuracy of any mathematical calculation or formulae under the Indenture, whether by the Company or any Person so authorized by the Company for such purpose under the Indenture or
      the failure by the Company to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any
      responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount of ADSs or securities or property (including cash) receivable by
      Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 11.02 of the Base Indenture, may accept (without any
      independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officer’s Certificate (which the Company shall be obligated to deliver to the Trustee prior to the
      execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion 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 until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices
      the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in
      Section 14.01(b). Except as otherwise expressly provided herein, neither the Trustee nor any other agent acting under the Indenture (other than the Company, if acting in such capacity) shall have any obligation to make any calculation or to determine
      whether the Notes may be surrendered for conversion pursuant to the Indenture, or to notify the Company or the Depositary or any of the Holders if the Notes have become convertible pursuant to the terms of the Indenture.

     

    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;

     

    
      64

      
        


    

    (b)          Merger Event; or

     

    (c)          voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

     

    then, in each case (unless notice of such event is otherwise required pursuant to another provision of the Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to
      each Holder at its address appearing on the 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 Class A 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 Class A Ordinary Shares or ADSs,
      as the case may be, of record shall be entitled to exchange their Class A 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, if any, delivered upon such conversion shall be entitled to receive (either directly or in respect of the Class A 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 of Notes, the rights
      have separated from the Class A 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 Class A 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.  Limit on Issuance of ADSs Upon Conversion. Notwithstanding anything to the contrary in the Indenture, if an event occurs
      that would result in an increase in the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules or listing standards of any national or regional securities exchange that are applicable to the Company, the
      Company will, at its option, either obtain stockholder approval of any issuance of ADSs upon conversion of the Notes in excess of such limitations or pay cash in lieu of delivering any ADSs otherwise deliverable upon conversions in excess of such
      limitations based on the Daily VWAP for each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering ADSs, the Company pays cash pursuant to this Section 14.12.

     

    Section 14.13.  Termination of Depositary Receipt Program. If the Class A Ordinary Shares cease to be represented by ADSs issued under a
      depositary receipt program sponsored by the Company, all references in the Indenture to the ADSs shall be deemed to have been replaced 

     

    

    
      65

      
        


    

    by a reference to the number of Class A Ordinary Shares (and other property, if any) represented by the ADSs on the last day on which the ADSs represented the Class A Ordinary Shares and as if the Class A 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 Class A 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. The Company shall provide written notice to the Holders, the Trustee and the Conversion Agent (if other than the Trustee) upon the occurrence of the foregoing.

     

    Section 14.14.  Exchange In Lieu Of Conversion. (a) When a Holder surrenders its Notes for conversion, the Company may, at its election
      (an “Exchange Election”), direct the Conversion Agent to deliver, on or prior to the Business Day immediately following the Conversion Date, such Notes to one or more financial institutions designated by the
      Company (each, a “Designated Financial Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the Designated Financial Institution(s) must agree to timely pay
      and/or deliver, as the case may be, in exchange for such Notes, the cash, ADSs or a combination thereof, as applicable, that would otherwise be due upon conversion pursuant to Section 14.02 (the “Conversion
        Consideration”). If the Company makes an Exchange Election, the Company shall, by the close of business on the Business Day following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent (if other than the
      Trustee) and the Holder surrendering Notes for conversion that the Company has made the Exchange Election and the Company shall promptly notify the Designated Financial Institution(s) of the relevant deadline for delivery of the Conversion
      Consideration and the type of Conversion Consideration to be paid and/or delivered, as the case may be.

     

    (b)          Any Notes delivered to the Designated Financial Institution(s) shall remain outstanding, subject to applicable procedures of the Depositary. If the Designated Financial Institution(s) agree(s) to accept any
      Notes for exchange but does not timely pay and/or deliver, as the case may be, the related Conversion Consideration, or if such Designated Financial Institution(s) does not accept the Notes for exchange, the Company shall pay and/or deliver, as the
      case may be, the relevant Conversion Consideration, as, and at the time, required pursuant to the Indenture as if the Company had not made the Exchange Election.

     

    (c)          The Company’s designation of any Designated Financial Institution(s) to which the Notes may be submitted for exchange does not require such Designated Financial Institution(s) to accept any Notes.

    Repurchase of Notes at Option of Holders

     

    Section 15.01.  Intentionally Omitted.

     

    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 

     

    

    
      66

      
        


    

    thereof that is equal to US$1,000 or an integral multiple of US$1,000, on the Business Day (the “Fundamental Change Repurchase Date”) notified in writing by the Company as set forth in Section 15.02(c) that
      is not less than 20 Business Days or more than 35 Business Days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued
      and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date
      but on or prior the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date on such Interest
      Payment 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 Fundamental Change Repurchase Date shall be subject to postponement to comply with
      applicable law.

     

    (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 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 at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary
      endorsements for transfer) 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 the Indenture;

     

    provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with applicable Depositary procedures.

     

    
      67

      
        


    

    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 at any time prior to the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in
      accordance with Section 15.03.

     

    The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

     

    (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 Paying Agent (in the case of a Paying
      Agent 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. 
      Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice on the Company’s website or through such other public medium as the Company may use at that
      time. Each Fundamental Change Company Notice shall specify:

     

    (i)           the events causing the Fundamental Change;

     

    (ii)          the date of the Fundamental Change;

     

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

     

    (iv)         the Fundamental Change Repurchase Price;

     

    (v)          the Fundamental Change Repurchase Date;

     

    (vi)         the name and address of the Paying Agent;

     

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

     

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

     

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

     

    
      68

      
        


    

    No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section
      15.02.

     

    At the Company’s written request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however,
      that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company and delivered to the Trustee no later than 2 Business Days (or such shorter period as is acceptable to the Trustee) prior to the date the
      Fundamental Change Company Notice is to be sent.

     

    (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 Paying Agent
      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 Fundamental Change Repurchase Notice. (i) A 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 in accordance with this Section 15.03 at any time prior to the close of business on the second Business Day immediately preceding the relevant
      Fundamental Change Repurchase Date, specifying:

     

    (ii)          the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which principal amount must be in principal amounts of US$1,000 or an integral
      multiple of US$1,000,

     

    (iii)         if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and

     

    (iv)         the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, 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 applicable procedures of the Depositary.

     

    Section 15.04.  Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent
      appointed by the Company), or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.03(b) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date, an amount
      of money sufficient to repurchase all of the Notes to be repurchased 

     

    

    
      69

      
        


    

    at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn in accordance with
      Section 15.03) will be made on the later of (i) the Fundamental Change Repurchase Date, (provided the Holder has satisfied the conditions in Section 15.02 and (ii) the time of book-entry transfer or the
      delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 15.02, as applicable, by mailing checks for the amount payable to the Holders of such Notes entitled thereto
      as they shall appear in the Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account
      of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

     

    (b)          If by 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or
      portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase to the Trustee (or other Paying Agent appointed by the Company) and not validly
      withdrawn, on such Fundamental Change Repurchase Date, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to
      the Trustee (or other Paying Agent appointed by the Company)) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price).

     

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

     

    The Company shall not be required to purchase, or to make an offer to purchase, the Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time, for the same or greater price
      and otherwise in compliance with the requirements for an offer made by the Company as set forth above in this Section 15.05 and such third party 

     

    

    
      70

      
        


    

    purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time, for the same or greater price and otherwise in compliance with the requirements for an offer made by the Company as set forth
      above in this Section 15.05.

     

    Notwithstanding anything to the contrary in this Supplemental Indenture, the Company shall not be required to send a Fundamental Change Company Notice, or offer to repurchase or repurchase any Notes, pursuant to Section
      15.02, in connection with a Fundamental Change occurring pursuant to clause (b)(A) or (b)(B) of the definition of Fundamental Change (or, for the avoidance of doubt, pursuant to clause (a) of the definition of Fundamental Change that also constitutes
      a Fundamental Change occurring pursuant to clause (b)(A) or (b)(B)) of the definition thereof), if:

     

    (i)           such Fundamental Change constitutes a share exchange event for which the resulting Reference Property consists entirely of cash in U.S. dollars;

     

    (ii)          immediately after such Fundamental Change, the Notes become convertible (pursuant to the provisions described in Section 14.07 and, if applicable, Section 14.03) into consideration that
      consists solely of U.S. Dollars in an amount per US$1,000 principal amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per US$1,000 principal amount of Notes (calculated assuming a Fundamental Change Repurchase Date that
      results in a Fundamental Change Repurchase Price that includes the maximum amount of accrued interest); and

     

    (iii)         the Company timely sends the notice required pursuant to Section 14.01(b)(iii).

     

    Any Fundamental Change with respect to which the Company does not offer to repurchase any Notes in accordance with the paragraph above shall be referred to as an “Exempted Fundamental
        Change.”

     

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

    Optional Redemption, Cleanup Redemption and Tax Redemption.

     

    Section 16.01.  Applicability of Article IV and Article V of the Base Indenture. Article IV and Article V of the Base Indenture shall
      not apply to the Notes. Instead the provisions set forth in this Article 16 shall, with respect to the Notes, supersede in their entirety Article IV of the Base Indenture, and all references in the Base Indenture to Article IV thereof and the
      provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 16 or the applicable provisions set forth in this Article 16, respectively.

     

    
      71

      
        


    

    Section 16.02.  Optional Redemption. (a) Except as described in Sections 16.03 and 16.04 below, the Notes may not be redeemed by the
      Company at its option prior to September 15, 2024. The Company may redeem for cash all or any part of the Notes, at its option, on a Redemption Date on or after September 15, 2024 and before the 42nd Scheduled Trading Day immediately preceding the
      Maturity Date, if the Last Reported Sale Price of the ADSs has been at least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period (including the last
      Trading Day of such period) ending on, and including, the Trading Day immediately preceding the Redemption Notice Date, (such redemption, an “Optional Redemption”).

     

    (b)          The Redemption Price for an Optional Redemption shall be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date; provided, however, that if the Redemption Date occurs after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then (i) the Company shall pay on the Interest Payment Date the full
      amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the record Holder of the Notes on the Regular Record Date corresponding to such Interest Payment Date, and (ii) the Redemption Price payable to the Holder who
      presents a Note for the Optional Redemption shall be equal to 100% of the principal amount of such Note, without the accrued and unpaid interest on such Note to, but excluding, the Redemption Date. The Redemption Date must be a Business Day.

     

    (c)          If less than all Notes then outstanding are called for an Optional Redemption, then the Trustee shall select the Notes to be redeemed (in principal amounts of US$1,000 or multiples thereof) by lot, on a pro
      rata basis (subject to rounding to the nearest US$1,000 principal amount) 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.

     

    (d)          If a portion of a Holder’s Notes are selected for a partial Optional Redemption and the Holder converts a portion of such Notes, the converted portion shall be deemed to be from the portion selected for such
      Optional Redemption.

     

    (e)          If the Company elects to redeem less than all of the outstanding Notes pursuant to this Section 16.02, and the Holder of any Note, or any owner of a beneficial interest in any Global Note, is reasonably not
      able to determine, before the close of business on the 43rd Scheduled Trading Day immediately preceding the Redemption Date (or, if the Company elects Physical Settlement for conversions that occur during the related Redemption Period, on the fourth
      Business Day immediately preceding the relevant Redemption Date), whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such Optional Redemption, then such Holder or owner, as applicable, will be entitled to convert
      such Note or beneficial interest, as applicable, at any time before the close of business on the second Business Day immediately before such Redemption Date, and each such conversion will be deemed to be of a Note called for Optional Redemption for
      purposes of this Section 16.02 and Section 14.03(g).

     

    (f)          In the event of any Optional Redemption in part, the Company shall not be required to register the transfer of or exchange any Note so selected for Optional Redemption, in whole or in part, except the
      non-redeemed portion of any Note being redeemed in part.

     

    
      72

      
        


    

    Section 16.03.  Cleanup Redemption. (a) The Company may redeem for cash all but not part of the Notes at any time, on a Redemption Date
      before the 42nd Scheduled Trading Day immediately preceding the Maturity Date, if less than US$250 million aggregate principal amount of Notes remains outstanding at such time (such redemption, a “Cleanup Redemption”).

     

    (b)          The Redemption Price for a Cleanup Redemption shall be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date; provided, however, that if the Redemption Date occurs after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then (i) the Company shall pay on the Interest Payment Date the full
      amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the record Holder of the Notes on the Regular Record Date corresponding to such Interest Payment Date, and (ii) the Redemption Price payable to the Holder who
      presents a Note for the Cleanup Redemption shall be equal to 100% of the principal amount of such Note, without the accrued and unpaid interest on such Note to, but excluding, the Redemption Date. The Redemption Date must be a Business Day.

     

    Section 16.04.  Tax Redemption. (a) If the Company has, or on the next Interest Payment Date would, become obligated to pay to the
      Holder of any Note Additional Amounts that are more than a de minimis amount, as a result of:

     

    (i)           any change or amendment on or after September 9, 2021 (or, in the case of a jurisdiction that becomes a Relevant Taxing Jurisdiction after such date, after such later date) in the laws or
      any rules or regulations of a Relevant Taxing Jurisdiction; or

     

    (ii)          any change on or after September 9, 2021 (or, in the case of a jurisdiction that becomes a Relevant Taxing Jurisdiction after such date, after such later date) in an interpretation,
      administration or application of such laws, rules or regulations by any legislative body, court, governmental agency, taxing authority or regulatory or administrative authority of such Relevant Taxing Jurisdiction (including the enactment of any
      legislation and the announcement or publication of any judicial decision or regulatory or administrative interpretation or determination);

     

    (each, a “Change in Tax Law”), the Company may, at its option, redeem all but not part of the Notes (except in respect of certain Holders that elect otherwise as described below) on a Redemption Date before
      the 42nd Scheduled Trading Day immediately preceding the Maturity Date; provided that the Company may only redeem the Notes if: (i) the Company cannot avoid such obligations by taking commercially reasonable
      measures available to the Company (provided that changing the jurisdiction of incorporation of the Company shall be deemed not to be a commercially reasonable measure); and (ii) the Company delivers to the
      Trustee an opinion of outside legal counsel of recognized standing in the Relevant Taxing Jurisdiction and an Officer’s Certificate attesting to such Change in Tax Law and obligation to pay Additional Amounts (such redemption, a “Tax Redemption”).

     

    (b)          The Redemption Price for a Tax Redemption shall be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date, including, any
      Additional Amounts with respect to such Redemption Price; provided, however, that if the Redemption Date occurs after a Regular Record Date and on or

     

    

    
      73

      
        


    

     prior to the corresponding Interest Payment Date, then (i) the Company shall pay on the Interest Payment Date the full amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the record Holder of the Notes on the
      Regular Record Date corresponding to such Interest Payment Date, and (ii) the Redemption Price payable to the Holder who presents a Note for the Tax Redemption shall be equal to 100% of the principal amount of such Note, including, for the avoidance
      of doubt, any Additional Amounts with respect to such Redemption Price, but without the accrued and unpaid interest on such Note to, but excluding, the Redemption Date. The Redemption Date must be a Business Day.

     

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

     

    Section 16.05.  Redemption Notice. (a) To call any Notes for a redemption pursuant to Article 16,
      the Company shall (x) provide a Redemption Notice not less than 44 Scheduled Trading Days but no more than 60 Scheduled Trading Days before the Redemption Date (provided that if the Company elects Physical
      Settlement for conversions that occur during the related Redemption Period, the Company may provide not less than 10 Business Days’ nor more than 30 Business Days’ notice before the Redemption Date) to the Trustee, the Conversion Agent (if other than
      the Trustee), the Paying Agent (if other than the Trustee) and each Holder of Notes selected for redemption, and (y) simultaneously therewith, publish a notice on the Company’s website or through such other public medium as the Company may use at
      that time containing the information set forth in the Redemption Notice.

     

    (b)          Such Redemption Notice must state:

     

    (i)           that the Notes have been called for redemption, briefly describing the Company’s redemption right under this Supplemental Indenture;

     

    (ii)          the Redemption Date for such redemption;

     

    (iii)         the Redemption Price per US$1,000 principal amount of Notes (and, if the Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner
      and timing of the interest payment payable);

     

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

     

    
      74

      
        


    

    (v)          that Notes called for redemption may be converted at any time during the related Redemption Period;

     

    (vi)         the Conversion Rate in effect on the Redemption Notice Date for such redemption and a description and quantification of any adjustments to the Conversion Rate that may result from such
      redemption (including pursuant to Section 14.03(g));

     

    (vii)        the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after such Redemption Notice Date and on or before the second Business Day before
      such Redemption Date; and

     

    (viii)       the CUSIP and ISIN numbers, if any, of the Notes.

     

    Section 16.06.  Conversion Election. Subject to the applicable procedures of DTC in the case of Global Notes, a Holder electing to not
      have its Notes redeemed pursuant to this Article 16 must deliver to the Company, with a copy to the Paying Agent a written notice of election so as to be received by the Company and the Paying Agent or
      otherwise by complying with the requirements for conversion in Section 14.02(b) prior to the close of business on the second Business Day immediately preceding the Redemption Date. 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 Company and the Paying Agent a written notice of withdrawal prior to the close of business on the Business Day immediately preceding the Redemption Date (or, if the
      Company fails to pay the Redemption Price on the Redemption Date, the Business Day immediately preceding the date on which the Redemption Price has been paid or duly provided for). If no election is made, the Holder shall have its Notes redeemed
      without any further action.

     

    No Notes may be redeemed if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the 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).

    Section 17.07.  Benefits of Indenture. Nothing in this Supplemental Indenture expressed and nothing that may be implied from any of the
      provisions hereof is intended, or shall be construed to confer upon, or to give to, any Person other than the parties hereto and their successors and the Holders of the Notes any benefit or any right, remedy or claim under or by reason of the
      Indenture or any covenant, condition, stipulation, promise or agreement hereof, and all covenants, conditions, stipulations, promises and agreements in the Indenture contained shall be for the sole and exclusive benefit of the parties hereto and

      Act and any other similar state laws based on the Uniform Electronic Transactions Act; provided that, notwithstanding anything herein to the contrary, the Trustee is not under any obligation to agree to
      accept electronic signatures in any form or in any format except for facsimile and PDF unless expressly agreed to by the Trustee pursuant to procedures approved by the Trustee.

     

    Section 17.09.  Severability. If any provision hereof shall be held to be invalid, illegal or unenforceable under applicable law, then

      registered Holder of Notes upon the written request of that Holder at the sole cost and expense of the Company. Neither the Trustee nor the Conversion Agent will have any responsibility to make calculations under this Supplemental Indenture, nor will
      either of them have any responsibility to monitor the Company’s stock or trading price, determine whether the conditions to convertibility of the Notes have been met or determine whether the circumstances requiring changes to the Conversion Rate have
      occurred.

      like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an
      account with the Trustee. The parties to the Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

    SEA LIMITED

     

    0.25% Convertible Senior Note due 2026

     

    This Note is one of a duly authorized issue of Notes of the Company, designated as its 0.25% Convertible Senior Notes due 2026 (the “Notes”), limited to the aggregate principal
      amount of US$2,875,000,000, all issued or to be issued under and pursuant to an Indenture dated as of September 14, 2021 (the “Base Indenture”), as amended and supplemented by the First Supplemental Indenture
      dated as September 14, 2021, (herein called the “Supplemental Indenture”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, and as it may be further amended or supplemented from
      time to time, the “Indenture”), each between the Company and Wilmington Trust, National Association, 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 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 case certain Events of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in
      aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture. In case certain Events of
      Default relating to a bankruptcy (or similar proceeding) with respect to the Company or a Significant Subsidiary of the Company shall have occurred, the principal of, and interest on, all Notes shall automatically become immediately due and payable,
      as set forth in the Indenture.

     

    Subject to the terms and conditions of the Indenture, the Company will make all payments in respect of the principal amount on the Maturity Date, the Redemption Price and the Fundamental Change Repurchase Price, as the
      case may be, to the Holder who surrenders a Note to the Trustee to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and
      private debts.

     

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

     

    
      A-5

      
        


    

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

     

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

     

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

     

    The Company may not redeem the Notes prior to the Maturity Date, except in the event of an Optional Redemption, a Cleanup Redemption or a Tax Redemption as described in Article 16
      of the Supplemental Indenture. No sinking fund is provided for the Notes.

     

    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 or an integral multiple thereof, into cash, ADSs or a combination of cash and ADSs, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

     

    Terms used in this Note and defined in the Indenture are used herein as therein defined.
