then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

Note so exchanged therefor shall not bear the Securities Act Legend specified in this Section 2.05(c) and shall not be assigned

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 (the “Depositary”). 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.
Beneficial interests in the Regulation S Global Notes may be held by any member of, or participants in, the Depositary, including
Euroclear and Clearstream (collectively, the “Agent Members”). Agent Members shall have no rights under this
Indenture with respect to any Global Notes held on their behalf by the Depositary, or the Trustee as its custodian, or under the
Global Notes, and the Depositary may be treated by the Company, the Trustee and any agent of either of them as the absolute owner
of such Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (i) prevent the Company,
the Trustee or any agent of either of them, from giving effect to any written certification, proxy or other authorization furnished
by the Depositary or (ii) impair, as between the Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a Holder of any Global Notes.


 


Holders of Global Notes will be entitled
to receive Physical Notes if (i) the Depositary (or any other clearing system as shall have been designated by the Company and
approved by the Trustee on behalf of which the Notes evidenced by the Rule 144A Global Note or the Regulations S Global Note may
be held) notifies the Company that it is no longer willing or able to discharge properly its responsibilities as depositary with
respect to the Global Notes or ceases to be a “Clearing Agency” registered under the Exchange Act or is at any time
no longer eligible to act as such and the Company is unable to locate a qualified successor within 60 days of receiving notice
of such ineligibility on the part of the Depositary Trust Company (or, as the case may be, such other clearing system), (ii) there
shall have occurred and be continuing an Event of Default, or (iii) instructions have been given for the transfer of an interest
in the Notes evidenced by the Rule 144A Global Note to a Person who would otherwise take delivery thereof in the form of an interest
in the Note evidenced by the Regulation S Global Note where the Regulation S Global Note has been exchanged for Physical Notes
or vice versa, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for
the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (ii) or (iii), a Physical Note
to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s
beneficial interest and (y) in the case of clause (i), 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.


 


In the case of Physical Notes, Holders of
a Physical Note may transfer such Note by surrendering it to the Note Registrar. In the event of a partial transfer or a partial
redemption of a holding of Physical Notes represented by one Physical Note, a Physical Note will be issued to the transferee in
respect of the part transferred and a new Physical Note in respect of the balance of the holding not transferred or redeemed will
be issued to the transferor or the Holder, as applicable; provided that no Physical Note in a denomination less than US$200,000
will be issued. The Company shall bear the cost of preparing, printing, packaging and delivering the Physical Notes.

Physical Notes delivered in exchange for
any Global Note or beneficial interest in Global Notes pursuant to this Section 2.05(c) shall be registered in such names and in
such authorized denominations requested by or on behalf of the Depositary (in accordance with its customary procedures) and will
bear the applicable legends specified in this Section 2.05, pursuant to instructions from its direct or indirect participants or
otherwise, 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. Physical Notes may be transferred and exchanged only after the transferor
first delivers to the Trustee a written certification (in the form provided in this Indenture) to the effect that such transfer
will comply with the transfer restrictions applicable to such Physical Notes.


 


Neither the Company, the Trustee nor any
agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments
made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.


 


(d)Until the Resale Restriction Termination
Date, any stock certificate representing ADSs (including any Class A Ordinary Shares represented thereby) issued upon conversion
of such Note shall bear a legend in substantially the following form (unless the Note or such ADSs or any Class A Ordinary Shares
represented thereby has been transferred pursuant to a registration statement that has become or been declared effective under
the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption from registration
provided by Rule 144 or any similar provision then in force under the Securities Act, or such ADSs or such Class A Ordinary Shares
represented thereby have been issued upon conversion of Notes that have been transferred pursuant to a registration statement that
has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer,
or pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities
Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the ADSs):

Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global
Note have been exchanged for Physical Notes or a particular Global Note has been converted, canceled, redeemed, repurchased or
transferred in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance
with Section 2.09. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred

Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee
or by the Depositary at the direction of the Trustee to reflect such increase.


 


Section
2.07             
Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost
or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed
by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in
exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen.
In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating
agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense
caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish
to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction,
loss or theft of such Note and of the ownership thereof.


 






    	25



    	 



    

 


The Trustee or such authenticating agent
may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee,
the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or
the Trustee may require the payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge
that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about
to mature or has been surrendered for required repurchase, is about to be converted in accordance with Article 14 or is about to
be redeemed in accordance with Article 16 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole
discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the
same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment
or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such
substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable,
any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof.


 


Every substitute Note issued pursuant to
the provisions of this Section 2.07 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall
be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately
with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the
express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase
or redemption of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable
instruments or other securities without their surrender.


 


Section
2.08             
Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes
(printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of
the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be
determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such
authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical
Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical
Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in
exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating
agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes.
Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary
Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical
Notes authenticated and delivered hereunder.


 






    	26



    	 



    

 


Section
2.09             
Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose
of payment, repurchase, redemption, registration of transfer or exchange or conversion, if surrendered to any Person other than
the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation.
All Notes delivered to the Trustee shall be canceled promptly by it, and no Notes shall be authenticated in exchange thereof except
as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with
its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s
written request in a Company Order. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption,
repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee
for cancellation.


 


Section
2.10             
CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” or “ISIN”
numbers (if then generally in use), and, if so, the Trustee shall use CUSIP or ISIN numbers in all notices issued to Holders as
a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification
numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the CUSIP or ISIN numbers.


 


Section
2.11             
Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section
2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder in

indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise,
whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to
private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other
than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation
in accordance with Section 2.09.

PARTICULAR COVENANTS OF THE COMPANY


 


Section
4.01             
Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal
(including the Tax Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, and
accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and
in the Notes.


 


Section
4.02             
Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York,
an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment,
repurchase or redemption (“Paying Agent”) or for conversion (“Conversion Agent”) and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. If the Company maintains
an additional Paying Agent in a European Union member state, the Company shall ensure that it maintains such Paying Agent in a
European Union member state that will not be obliged to withhold or deduct tax pursuant to European Council Directive 2003/48/EC
or any other Directive implementing the conclusions of the ECOFIN Council meeting of November 26-27, 2000 or any law implementing
or complying with, or introduced in order to conform to, such Directive (so long as there is such a member state). The Company
will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at
any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the corporate
trust office of the Trustee in the Borough of Manhattan, The City of New York.


 


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

The Company hereby initially designates
(i) Citibank, N.A. as the Paying Agent, the Conversion Agent and the transfer agent and (ii) the Corporate Trust Office and the
corporate trust office of the Trustee in the Borough of Manhattan, The City of New York as an office or agency of the Company for
purposes of this Section 4.02.


 


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

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


 


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


 


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


 


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


 


The Company shall, no later than 10:00 a.m.,
New York City time, on the Business Day immediately preceding each due date of the principal (including the Tax Redemption Price,
the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes,
deposit with the Paying Agent a sum sufficient to pay such principal (including the Tax Redemption Price, the Repurchase Price
and the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of any failure to take such action. Any deposit by the Company with the Paying
Agent shall be made by wire transfer in immediately available funds.


 


To the extent the Paying Agent will act
as the Company’s withholding agent with respect to any payment of principal (including the Tax Redemption Price, the Repurchase
Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, the Company
shall, no later than 10:00 a.m., New York City time, on the Business Day immediately preceding the due date of such payment, furnish

shall also specify in the Officers’ Certificate the amount required to be so withheld and the Additional Amounts, if any.
For the avoidance of doubt, the Company shall deposit such Additional Amounts, if any, with the Paying Agent in accordance with

failure by the Company to make any payment of the principal (including the Tax Redemption Price, the Repurchase Price and the Fundamental
Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture,
or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any
Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein
contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent
shall be released from all further liability but only with respect to such sums or amounts.

the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Tax Redemption
Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and
the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Tax

as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money and ADSs, and all liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company
cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, notice that such money and ADSs remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of

Section
4.06             
Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to Section
13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or the ADSs delivered upon conversion thereof
shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities
Act, promptly provide to the Trustee and shall, upon written request, provide to any Holder, beneficial owner or prospective purchaser
of such Notes or such ADSs the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate
the resale of such Notes or such ADSs pursuant to Rule 144A under the Securities Act. The Company shall take such further action
as any Holder or beneficial owner of such Notes or such ADSs may reasonably request from time to time to enable such Holder or
beneficial owner to sell such Notes or such ADSs in accordance with Rule 144A under the Securities Act, as such rule may be amended
from time to time.


 


(b)The Company shall file with the Trustee
within 15 days after the same are required to be filed with the Commission, copies of any documents or reports that the Company
is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period
provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the
Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) as of the time
such documents are filed with the Commission via the EDGAR system; provided that the Company will notify the Trustee within 15
days of any such filing.


 


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


 


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

Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Persons who were the Company’s
Affiliates during the three immediately preceding months (without restrictions pursuant to U.S. securities law or the terms of
this Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes, the Company shall pay Additional
Interest on the Notes. Such Additional Interest will accrue on the Notes at the rate of 0.50% per annum of the principal amount
of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are
assigned an unrestricted CUSIP number and the Notes are freely tradable by Holders other than the Company’s Affiliates or
Persons who were the Company’s Affiliates during the three immediately preceding months (without restrictions pursuant to
U.S. securities law or the terms of this Indenture or the Notes).

(f)Additional Interest will be payable
in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes.


 


(g)The Additional Interest that is payable
in accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that
may be payable as a result of the Company’s election pursuant to Section 6.03.


 


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

authority thereof or therein) (each, as applicable, a “Relevant Taxing Jurisdiction”), 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 beneficial owner after such withholding
or deduction (and after deducting any taxes on the Additional Amounts) shall equal the amounts that would have been received by
such beneficial owner had no such withholding or deduction been required; provided that that no Additional Amounts shall be payable:


 


(i)for or on account of:


 


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

or beneficial owner, as the case may be, to provide certification, information, documents or other evidence concerning such Holder’s
or beneficial owner’s nationality, residence, identity or connection with the Relevant Taxing 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 Taxing Jurisdiction to reduce or
eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such Holder or beneficial
owner;


 


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


 


(C)any taxes imposed pursuant
to Sections 1471 to 1474 of the United States Internal Revenue Code of 1986, as amended, including any current or former United
States Treasury Regulations or other official interpretations or guidance thereunder, any agreements or intergovernmental agreements
thereunder, and any law implementing any intergovernmental agreement relating thereto;


 


(D)any tax, duty, assessment
or other governmental charge that is payable otherwise than by withholding from payments under or with respect to the Notes; 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 Repurchase Price or Fundamental Change Repurchase Price, if applicable), premium, if any, and
interest on, 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 Taxing
Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a member of that partnership or a beneficial
owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner or beneficial owner been
the Holder thereof.

Amounts, unless the context requires otherwise, that may be payable with respect to that amount under the obligations referred
to in this Section 4.07.


 


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

shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest
on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants
or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution

Default that occurred during the previous year, and, if so, specifying each such failure and the nature thereof.


 


In addition, the Company shall deliver to
the Trustee, within 30 days after the Company becomes aware of the occurrence of any Event of Default or Default, an Officers’
Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company proposes
to take with respect thereto.


 


Section
4.10

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 borne by the Notes, plus one percent at such time) and amounts due to the Trustee pursuant to Section
7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and
all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest,
if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09,
then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate
principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or
Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall
impair any right consequent thereon. Notwithstanding the above or 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, the Tax Redemption Price on the Tax Redemption Date, or the Repurchase Price
on the Repurchase Date or Fundamental Change Repurchase Price (ii) a failure to pay or deliver, as the case may be, the consideration
due upon conversion of the Notes in accordance with this Indenture or (iii) in respect of any provision under this Indenture that
cannot be modified or amended without the consent of the Holders of each outstanding Note affected.


 


Section
6.03             
Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent
the Company elects, the sole remedy for Events of Default relating to the Company’s failure to comply with its obligations
as set forth in Section 4.06(b) shall after the occurrence of such an Event of Default consist exclusively of the right to receive
Additional Interest on the Notes at a rate equal to (a) 0.25% per annum of the principal amount of the Notes outstanding for each
day during the 180-day period beginning on, and including, the date on which such an Event of Default first occurs and (b) 0.50%
per annum of the principal amount of the Notes outstanding for each day during the 180-day period beginning on, and including,
the 181st day following, and including, the occurrence of such an Event of Default during which, in each case, such Event of Default
is continuing. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional
Interest payable pursuant to Section 4.06(d) or Section 4.06(e). 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 361st day after such Event of Default (if the
Event of Default relating to the Company’s failure to file is not cured or waived prior to such 361st day), the Notes shall
be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest following
an Event of Default in accordance with this Section 6.03, the Notes shall be subject to acceleration as provided in Section 6.02.


 


In order to elect to pay Additional Interest
as the sole remedy during the first 360 days after the occurrence of any Event of Default described in the immediately preceding
paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning
of such 360-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as
provided in Section 6.02.

Section
6.04             
Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section
6.01 shall have occurred, the Company shall, upon demand of the Trustee, 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 borne by the Notes, plus one percent at such time, and, in addition thereto, such
further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to
pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree
and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to
be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.


 


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


 






    	38



    	 



    

 


Nothing herein contained shall be deemed
to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.


 


All rights of action and of asserting claims
under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or
the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment
of the compensation, 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 this Indenture to which the Trustee shall be a party)
the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes
parties to any such proceedings.


 


In case the Trustee shall have proceeded
to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver
pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined
adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination
in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers
of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted.

thereof, if fully paid:

(to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes
at such time, such payments to be made ratably to the Persons entitled thereto;


 


Third, in case the principal of the outstanding
Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable,
the payment of the Tax Redemption Price, the Repurchase Price, the Fundamental Change Repurchase Price and any cash in lieu of
fractional ADSs 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 borne by the Notes at such time, plus one percent, and in case such monies shall be insufficient to pay in full the
whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Tax Redemption
Price, the Repurchase Price, the Fundamental Change Repurchase Price and any cash in lieu of fractional ADSs due upon conversion)
and interest without preference or priority of principal over interest, or of interest over principal or of any installment of

in lieu of fractional ADSs due upon conversion) and accrued and unpaid interest; and

the Tax Redemption Price on the Tax Redemption Date, the Repurchase Price on the Repurchase Date or Fundamental Change Repurchase
Price) or accrued and unpaid interest, if any, or the right to receive payment or delivery of the consideration due upon conversion,

action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver,
trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit

incurred therein or thereby;


 


(d) the Trustee for 60 days after its
receipt of such notice of the request and offer of security or indemnity satisfactory to it in its sole discretion, shall have

(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 in
principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09,


 


it being understood and intended, and being
expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more
Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb
or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder,
or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit
of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder
and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this
Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the

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


 


Section
6.07             
Proceedings by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect
and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and
enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether
for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted
in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.


 


Section
6.08             
Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07, 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 other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings
or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay
or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event
of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default
or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or
by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Holders.

principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct
the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee with respect to Notes; provided, however, that the Trustee may refuse to follow any direction that (i)
conflicts with law or with this Indenture, or (ii) that the Trustee determines unduly prejudicial to the rights of any other Holder
or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be
entitled to indemnification satisfactory to the Trustee in its sole discretion against all loses and expenses caused by taking
or not taking such action. The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding determined
in accordance with Section 8.04 may on behalf of the Holders of all of the Notes, by notice to the Trustee, waive any past Default
or Event of Default hereunder and its consequences except a Default or Event of Default (i) in the payment of accrued and unpaid

Notes in accordance with this Indenture or (iii) in respect of any 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 a Default or Event of Default or impair any right consequent thereon. Whenever any Default
or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall
for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section
6.10             
Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of
which a Responsible Officer has actual knowledge, mail to all Holders as the names and addresses of such Holders appear upon the

the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Tax
Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, as 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 a committee of Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders. The Trustee shall not be deemed to have knowledge of a Default
or Event of Default (other than a Default in the payment of principal of (including the Tax Redemption Price, the Repurchase Price
and the Fundamental Change Repurchase Price, as applicable), or accrued and unpaid interest on, any of the Notes) unless a Responsible
Officer of the Trustee has received written notice thereof in the manner provided in this Indenture, which notice references the
Notes and the Indenture.


 


Section

Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance
thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion
assess 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 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted
by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding
determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the
principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Tax Redemption Price with
respect to the Notes being redeemed and the Repurchase Price or Fundamental Change Repurchase Price with respect to the Notes

ARTICLE
7

CONCERNING THE TRUSTEE


 


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


 


No provision of this Indenture shall be
construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act
or its own willful misconduct, except that:


 


(a) prior to the occurrence of an Event
of Default and after the curing or waiving of all Events of Default that may have occurred:


 


(i) the duties and obligations
of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except
for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and


 


(ii) in the absence of bad
faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to
the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations
or other facts stated therein);


 


(b) the Trustee shall not be liable
for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that
the Trustee was grossly negligent in ascertaining the pertinent facts;


 


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


 






    	43



    	 



    

 


(d) whether or not therein provided,
every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee
shall be subject to the provisions of this Section;


 


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


 


(f) if any party fails to deliver a
notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee
may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred;


 


(g) in the absence of a written agreement
executed by the Company and the Trustee and written investment direction from the Company pursuant thereto, all cash received by
the Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for interest thereon,
or the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation
of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity
date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall
have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the
Company; and


 


(h) in the event that the Trustee or
an affiliate is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the rights
and protections afforded to the Trustee pursuant to this Article 7 (including indemnity) shall also be afforded to such Custodian,
Note Registrar, Paying Agent, Conversion Agent or transfer agent.


 


If an Event of Default occurs and is continuing,
the Trustee may require the Paying Agent and Conversion Agent to act under its direction.


 


None of the provisions contained in this
Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance
of any of its duties or in the exercise of any of its rights or powers. Where there are any inconsistencies between the Trustee
Ordinance (Cap. 29 Laws of Hong Kong) and this Indenture, the provisions of this Indenture shall prevail to the extent provided
or permitted by law.

or presented by the proper party or parties;

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


 


(d) the Trustee shall not be bound to
make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report,
notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally
or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation;


 


(e) the Trustee may execute any of the
trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys
and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney
appointed by it with due care hereunder; and


 


(f) the permissive rights of the Trustee
enumerated herein shall not be construed as duties.


 


In no event shall the Trustee be liable
for any special, punitive or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even
if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. The Trustee shall
not be charged with knowledge of any Default or Event of Default (other than a Default in the payment of principal of (including
the Tax Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid
interest on, any of the Notes) unless a Responsible Officer of the Trustee has received written notice thereof in the manner provided
in this Indenture, which notice references the Notes and the Indenture.


 


Section
7.03             
No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s
certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for
the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the
Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes
authenticated and delivered by the Trustee in conformity with the provisions of this Indenture.


 


Section
7.04             
Individual Rights or the Trustee, Paying Agents, Conversion Agents or Note Registrar. The Trustee, any Paying
Agent, any Conversion Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes
and may otherwise engage in business or deal with the Company or its Affiliates with the same rights it would have if it were
not the Trustee, Paying Agent, Conversion Agent or Note Registrar. Nothing herein shall obligate the Trustee, the Conversion Agent,
the Notes Registrar or the Paying Agent to account for any profits earned from any business or transactional relationship. The
Trustee may have interest in or may be providing or may in the future provide financial or other services to other parties. The
Conversion Agent, Paying Agent and the Notes Registrar may do the same with like rights.

as herein provided, be held in trust for the purposes for which they were received. Money and ADSs held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability
for interest on any money or ADSs received by it hereunder except as may be agreed from time to time by the Company and the Trustee.


 


Section
7.06             
Compensation and Expenses of Trustee, Payment Agents, Conversion Agents and Note Registrar. The Company covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services
rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of
a trustee of an express trust) as mutually agreed to in writing between and executed by the Trustee and the Company, and the Company
will pay or reimburse the Trustee upon its request for all expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable compensation and
the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad faith. Any payment by the
Company to the Trustee shall be made by wire transfer in immediately available funds. The Company also covenants to indemnify
the Trustee (which for purposes of this Section 7.06 shall be deemed to include its directors, officers, employees and agents)
in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents
and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without
gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or
such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration
of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of
liability in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to
pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes are
hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section 6.05,
funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment
of any amounts due under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The
obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier
resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents
and employees of the Trustee.


 


Without prejudice to any other rights available
to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services
are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section

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

Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least US$50,000,000. If such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such
resignation to the Company and by mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register.
Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 days
after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice
to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor trustee, or any
Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11,
on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such
court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.


 


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


 


(i)the Trustee shall cease
to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after written request therefor by the
Company or by any such Holder, or

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


 


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


 


(d) Any resignation or removal of the
Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 7.10.


 


Section
7.10             
Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any
further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder,
with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section
7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing
to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully
and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected
by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts
then due it pursuant to the provisions of Section 7.06.


 


No successor trustee shall accept appointment
as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions
of Section 7.08.


 


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


 


Section
7.11

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

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

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

CONCERNING THE HOLDERS


 


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

Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and Section 9.05,
proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such
reasonable rules and regulations as may be prescribed by the Trustee or the Depositary or in such manner as shall be satisfactory
to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record
of any Holders’ meeting shall be proved in the manner provided in Section 9.06.


 


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


 


Section
8.04             
Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount
of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company
or by any Affiliate of the Company 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 that a Responsible Officer knows are so owned shall be so disregarded. Notes so owned that have
been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish
to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not
the Company or an Affiliate of the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon
the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee
promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by
or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept
such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed
therein are outstanding for the purpose of any such determination.

of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange
or substitution therefor or upon registration of transfer thereof.

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

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


 


(a) the resulting, surviving or transferee
Person (the “Continuing Entity”), if not the Company, shall be a corporation organized and existing under the
laws of any State of the United States of America or the District of Columbia, or a company organized and existing under the laws
of the Cayman Islands, and the Continuing Entity (if not the Company) shall expressly assume, by supplemental indenture all of
the obligations of the Company under the Notes and this Indenture (including, for the avoidance of doubt, the obligation to pay
Additional Amounts pursuant to Section 4.07(a));

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


 


(c)if, pursuant to Section 14.07, upon
the occurrence of any such consolidation, merger, sale, conveyance, transfer or lease the Notes would become convertible into securities
issued by an issuer other than the Continuing Entity, such other issuer shall fully and unconditionally guarantee on a senior basis
the resulting Continuing Entity’s obligations under the Notes.


 


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

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


 


Section
11.03          Opinion

the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation,
merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection
with such transaction, such supplemental indenture, complies with the provisions of this Article 11.

CONVERSION OF NOTES


 


Section
14.01          Conversion
Privilege. Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right,
at such Holder’s option, at any time prior to the close of business on the third Business Day immediately preceding the
Maturity Date, to convert all or any portion (if the portion to be converted is US$1,000 principal amount or an integral multiple
thereof) of such Note at an initial conversion rate of 7.9789 ADSs (subject to adjustment as provided in Section 14.04, the “Conversion
Rate”) per US$1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion
Obligation”).


 


Section
14.02          Conversion
Procedure; Settlement Upon Conversion.





(a) Upon conversion of any Note, the Company shall cause to be delivered to
the converting Holder, in respect of each US$1,000 principal amount of Notes being converted, a number of ADSs equal to the Conversion
Rate, together with a cash payment, if applicable, in lieu of any fractional ADS in accordance with subsection (j) of this Section
14.02, on the third Business Day immediately following the relevant Conversion Date.


 






    	57



    	 



    

 


(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 for book-entry transfer to the Conversion Agent through the
facilities of the Depositary and, if required, pay funds to the Issuer directly equal to interest payable on the next Interest
Payment Date to which such Holder is not entitled as set forth in Section 14.02(i) and, if required, pay documentary, stamp or
similar issue or transfer tax, if any, and provide an original signed notice of conversion with a medallion guaranty stamp on the
reverse side of the Note as set forth in the Form of Notice of Conversion (a “Notice of Conversion”) and/or
other appropriate clearing agency message and effect book-entry transfer or delivery of the Notes, together with necessary endorsements
and (ii) in the case of a Physical Note (1) complete and manually sign Notice of Conversion or a facsimile of the Notice of Conversion,
(2) deliver the original Notice of Conversion with a medallion guaranty stamp and/or appropriate clearing agency message, which
is irrevocable, and the Note to 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, (3) furnish appropriate endorsements and transfer documents, and,
ADS delivery instructions and pay applicable Depositary fees directly, (4) if required, pay to the Issuer directly 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(i) and
(5) if required, pay any tax or duty which may be payable in respect of any transfer involving the issue or delivery of the ADSs
in the name of a Person other than such Holder. The Trustee (and if different, the Conversion Agent) shall notify the Company of
any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to
any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Repurchase Notice or Fundamental Change Repurchase
Notice to the Company in respect of such Notes and not validly withdrawn such Repurchase Notice or Fundamental Change Repurchase
Notice in accordance with Section 15.03.


 


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, provided that such procedures must be complied with on or prior
to 2:00 PM (New York time) on a Business Day in order for the conversion to be processed on the same date. The Company shall issue
or cause to be issued, and deliver to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer
through the Depositary for the full number of ADSs to which such Holder shall be entitled in satisfaction of the Conversion Obligation.


 


(d) In case any 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 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.


 






    	58



    	 



    

 


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


 


(f)The Company shall undertake to maintain,
as long as the Notes are outstanding, the effectiveness of a registration statement on Form F-6 relating to the ADSs and an adequate
number of ADSs available for issuance thereunder such that ADSs can be delivered in accordance with the terms of this Indenture,
the Notes and the Deposit Agreement upon conversion of the Notes.


 


(g) 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.


 


(h) 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.


 


(i) Upon conversion, a Holder shall not
receive any separate cash payment or any Additional ADSs accrued and unpaid interest, if any, except as set forth below. The Company’s
settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note
and accrued and unpaid interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest,
if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.
Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes
as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding
Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business
on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds
equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for Notes
converted after the close of business on the Regular Record Date immediately preceding the Maturity Date and before the close of
business on the third Business Day immediately preceding the Maturity Date; (2) if the Company has specified a Tax Redemption Date
that is after a Regular Record Date and on or prior to the Scheduled Trading Day immediately following the corresponding 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 Scheduled Trading Day immediately following the corresponding Interest Payment Date; or (4) to the extent of any
Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such Note.


 






    	59



    	 



    

 


(j) The Person in whose name the certificate
for any ADSs delivered upon conversion is registered shall be deemed to become the holder of record of such ADSs as of the close
of business on the relevant Conversion Date. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes
surrendered for conversion.


 


(k) The Company shall not cause to be
delivered any fractional ADSs upon conversion of the Notes and shall instead pay cash in lieu of any fractional ADS issuable upon
conversion based on the Last Reported Sale Price of the ADSs on the relevant Conversion Date.


 


Section
14.03          Increased
Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes or Tax Redemptions.



 


(a) If (i) either (X) a Make-Whole Fundamental Change occurs prior to the Maturity Date or (Y) the Company delivers a Tax
Redemption Notice, and in each case, (ii) a Holder elects to convert its Notes in connection with such Make-Whole Fundamental
Change or such Tax Redemption, then 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 to, and including, the third Business Day immediately prior to the related Fundamental
Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the
proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole
Fundamental Change). A conversion of Notes shall be deemed for these purposes to be “in connection with” a
Tax Redemption if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the date the Company
delivers a Tax Redemption Notice to, and including, the Business Day immediately prior to the related Tax Redemption Date (or
if the Company fails to pay the Tax Redemption Price (such later date on which the Company pays the Tax Redemption Price)).


 


(b) Upon surrender of Notes for conversion
in connection with a Make-Whole Fundamental Change, the Company cause to be delivered ADSs, including the Additional ADSs, in accordance
with Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b)
of the definition of Fundamental Change, the Reference Property 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. The Company shall notify the
Holders of Notes, the Trustee, the Conversion Agent and the Paying Agent of the Effective Date of any Make-Whole Fundamental Change
and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.


 


(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 (i) the date
on which the Make-Whole Fundamental Change occurs or becomes effective or, in the case of a Tax Redemption, the date on which the
Company delivers a Tax Redemption Notice (in each case, the “Effective Date”) and (ii) in the case of a Make-Whole
Fundamental Change, the price paid (or deemed to be paid) per ADS in connection with such Make-Whole Fundamental Change or, in
the case of a Tax Redemption, 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 date on which the Company delivers a Tax Redemption Notice (in each
case, the “ADS Price”). If the holders of ADSs receive 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 share. Otherwise, the ADS
Price shall be the average of the Last Reported Sale Prices of the ADSs for each Trading Day during the five Trading-Day period
ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board
of Directors shall make appropriate adjustments to the ADS Price, in its good faith determination, to account for any adjustment
to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend
Date of the event occurs, during such five consecutive Trading-Day period.

(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.

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 based on a 365-day year, as applicable;


 


(ii) if the ADS Price is greater
than US$300.00 per share (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


 






    	61



    	 



    

 


(iii) if the ADS Price is
less than US$91.15 per share (subject to adjustment in the same manner as the ADS Prices set forth in the column headings of the
table above pursuant to subsection (d) above), no Additional ADSs shall be added to the Conversion Rate.


 


Notwithstanding the foregoing, in no event
shall the total number of ADSs issuable upon conversion exceed 10.9709 per US$1,000 principal amount of Notes, 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 in respect of a Make-Whole Fundamental Change.


 


Section
14.04          Adjustment
of Conversion Rate. If the number of Class A Ordinary Shares represented by the ADSs is changed 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 deliverable upon conversion of any Notes is not affected
by such change.


 


Notwithstanding the adjustment provisions
described in this Section 14.04, if the Company distributes to all or substantially all holders of the Ordinary Shares any cash,
rights, options, warrants, shares of capital stock or similar equity interest, evidences of indebtedness or other assets or property
of the Company (but excluding Expiring Rights) and, in lieu of a corresponding distribution to holders of the ADSs, the ADSs shall
instead 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 unless and until a corresponding distribution (if any) is made to holders of
the ADSs, and in which case such adjustment to the Conversion Rate shall be based on the distribution made to the holders of the
ADSs and not on the distribution made to the holders of the Ordinary Shares. However, in the event that the Company issues or distributes
to all or substantially all holders of the Ordinary Shares any Expiring Rights, notwithstanding the immediately preceding sentence,
the Company shall adjust the Conversion Rate pursuant to Section 14.04(b) (in the case of Expiring Rights entitling holders of
the Ordinary Shares for a period of not more than 45 calendar days after the announcement date of such issuance to subscribe for
or purchase Ordinary Shares or ADSs) or Section 14.04(c) (in the case of all other Expiring Rights). “Expiring Rights”
means any rights, options or warrants to purchase Ordinary Shares or ADSs that expire on or prior to the Maturity Date.


 


For the avoidance of doubt, if any event
described in this Section 14.04(a) to 14.04(c) (inclusive) 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 adjust the Conversion Rate on account
of such event to the extent, but only to the extent, that such change reflects the adjustment to the Conversion Rate that would
otherwise have been required on account of such event.


 


Subject to the foregoing, 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 share split or share
combination), 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 in effect immediately prior to the effective time for such adjustment, multiplied by the principal amount
(expressed in thousands) of Notes held by such Holder.


 






    	62



    	 



    

 


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


 


	CR1 = CR0 x	OS1
	OS0


 


where,


 


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



 


		CR1 =	the Conversion Rate in effect immediately after the
close of business on such Record Date or immediately after the open of business on such Adjustment Effective Date, as applicable;



 


		OS0 =	the number of Ordinary Shares outstanding immediately
prior to the close of business on such Record Date or immediately prior to the open of business on such Adjustment Effective Date,
as applicable; and



 


		OS1 =	the number of Ordinary Shares outstanding immediately
after giving effect to such dividend, distribution, share split or share combination.



 


Any adjustment made under this Section 14.04(a)
shall become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately
after the open of business on the Adjustment 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. For the avoidance of doubt,
the references to “Ordinary Shares” in “OS0” and “OS1” above include
without limitation both Class A Ordinary Shares and Class B Ordinary Shares.

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


 


	CR1 = CR0 x	OS0 + X
	OS0 + Y


 


where,


 


		CR0=	the Conversion Rate in effect immediately prior to
the close of business on the Record Date for such issuance;



 


		CR1=	the Conversion Rate in effect immediately after the
close of business on such Record Date;



 


		OS0=	the number of Ordinary Shares outstanding immediately
prior to the close of business on such Record Date;



 


		X =	the total number of Ordinary Shares issuable pursuant
to such rights, options or warrants or, in the case of any rights, options or warrants entitling holders thereof to subscribe
for or purchase ADSs, the total number of Class A Ordinary Shares represented by the total number of ADSs issuable pursuant to
such rights, options or warrants; and



 


		Y =	the number of Ordinary Shares equal to the aggregate
price payable to exercise such rights, options or warrants, divided by 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) for each Trading Day during 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.



 


Any increase made under this Section 14.04(b)
shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after
the close of business on the Record Date for such issuance. To the extent that the Ordinary Shares or ADSs, as the case may be,
are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion
Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on
the basis of delivery of only the number of Ordinary Shares or ADSs, as the case may be, actually delivered. If such rights, options
or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
Record Date for such issuance had not occurred. For the avoidance of doubt, the references to “Ordinary Shares” in
“OS0” above include without limitation both Class A Ordinary Shares and Class B Ordinary Shares.


 


For purposes of this Section 14.04(b), in
determining whether any rights, options or warrants entitle the holders to subscribe for or purchase Ordinary Shares or ADSs at
less than such average of the Last Reported Sale Prices of the ADSs (in the case of any rights, options, warrants entitling holders
thereof to subscribe for or purchase Ordinary Shares, divided by the number of Class A Ordinary Shares then represented
by one ADS) for each Trading Day during the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately
preceding the date of announcement of such issuance, and in determining the aggregate offering price of such Ordinary Shares or
ADSs, as the case may be, 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
reasonably determined by the Board of Directors or a committee thereof in good faith.

(c) If the Company distributes shares
of its Capital Stock, evidences of its indebtedness, other assets or property or rights, options or warrants to acquire its Capital
Stock or other securities, to all or substantially all holders of the Ordinary Shares, excluding (i) dividends, rights, options
or warrants as to which an adjustment has been 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 has been effected pursuant to Section 14.04(d) or Section 14.04(e), and (iii)
Spin-Offs (as defined below) as to which the provisions set forth below in this Section 14.04(c) shall apply (any of such shares
of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or
other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based
on the following formula:


 


	CR1 = CR0 x	SP0
	SP0 - FMV


 


where,


 


		CR0 =	the Conversion Rate in effect immediately prior to
the close of business on the Record Date for such distribution;



 


		CR1 =	the Conversion Rate in effect immediately after the
close of business on such Record Date;



 


		SP0 =	the average of the Last Reported Sale Prices of the
ADSs (divided by the number of Class A Ordinary Shares then represented by one ADS) for each Trading Day during 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 reasonably determined by
the Board of Directors or a committee thereof in good faith) of the Distributed Property with respect to each outstanding Ordinary
Share on the Ex-Dividend Date for such distribution.



 


Any increase made under the portion of this
Section 14.04(c) above shall become effective immediately after the close of business on the Record Date for such distribution.
If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared.


 


If the Board of Directors determines the
“FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual
or when-issued trading market for any securities, in doing so it shall consider the prices in such market over the same period
used in computing 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 Ex-Dividend Date for such distribution.


 






    	65



    	 



    

 


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 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 distribution.


 


With respect to an adjustment pursuant to
this Section 14.04(c) where there has been a payment of a dividend or other distribution on the Ordinary Shares 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,
where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the Spin-Off)
on a U.S. national or regional securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based
on the following formula:


 


	CR1 = CR0 x	FMV0 + MP0
	MP0


 


where,


 


		CR0 =	the Conversion Rate in effect immediately prior to
the end of the Valuation Period;



 


		CR1 =	the Conversion Rate in effect immediately after the
end of the Valuation Period;



 


		FMV0 =	the average of the Last Reported Sale Prices of the
Capital Stock or similar equity interest distributed to holders of the Ordinary Shares applicable to one Ordinary Share (determined
for purposes of the definition of Last Reported Sale Price as set forth in Section 1.01 as if such Capital Stock or similar equity
interest were ADSs) for each Trading Day during the first 10 consecutive Trading-Day period beginning on, 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 be determined on the last Trading Day of the Valuation Period but will be given effect immediately
after the open of business on the Ex-Dividend Date for the Spin-Off; provided that in respect of any conversion during the Valuation
Period, references in the portion of this Section 14.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced
with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including,
the Conversion Date in determining the Conversion Rate.


 






    	66



    	 



    

 


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


 


(A) a dividend or distribution of Ordinary
Shares 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 adjustment to the Conversion Rate 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 adjustment to the Conversion Rate required
by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I)
the “Record Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Record
Date of the Clause C Distribution and (II) any Ordinary Shares included in the Clause A Distribution or Clause B Distribution shall
be deemed not to be “outstanding immediately prior to the close of business on such Record Date or immediately after the
open of business on such Adjustment Effective Date, as applicable” within the meaning of Section 14.04(a) or “outstanding
immediately prior to the close of business on such Record Date” within the meaning of Section 14.04(b).


 






    	67



    	 



    

 


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


 


	CR1 = CR0 x	SP0
	SP0 - C


 


where,


 


		CR0 =	the Conversion Rate in effect immediately prior to
the close of business on the Record Date for such dividend or distribution;



 


		CR1 =	the Conversion Rate in effect immediately after the
close of business on the Record Date for such dividend or distribution;



 


		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) for each Trading Day during the 10
consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the Ex- Dividend Date for such
dividend or distribution; and



 


		C =	the amount in cash per Ordinary Share the Company
distributes to holders of its Ordinary Shares.



 


Any increase made under this Section 14.04(d)
shall become effective immediately after the close of business on the Record Date for such dividend or distribution. If such dividend
or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines
not to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared.


 


Notwithstanding the foregoing, if “C”
(as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, for each US$1,000 principal amount of Notes, at the same time and upon the same
terms as holders of 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 such cash dividend or distribution.


 






    	68



    	 



    

 


(e) If the Company or any of its Subsidiaries
makes a payment in respect of a tender or exchange offer for the Ordinary Shares or ADSs, if the cash and value of any other consideration
included in the payment per Ordinary Share or ADS exceeds the average of the Last Reported Sale Prices of the ADSs (in the case
of a tender or exchange offer for Ordinary Shares, divided by the number of Class A Ordinary Shares then represented by
one ADS) for each Trading Day during the 10 consecutive Trading-Day period beginning on, and including, the Trading Day next succeeding
the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be
increased based on the following formula:


 


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


 


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 reasonably determined by the Board of Directors or a committee thereof in good faith) paid or payable for all Ordinary Shares
or ADSs, as the case may be, purchased in such tender or exchange offer;



 


		OS0 =	the number of Ordinary Shares outstanding immediately
prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all Ordinary Shares and ADSs
accepted for purchase or exchange in such tender or exchange offer);



 


		OS1 =	the number of Ordinary Shares outstanding immediately
after the date such tender or exchange offer expires (after giving effect to the purchase of all Ordinary Shares and ADSs accepted
for purchase or exchange in such tender or exchange offer); and



 


		SP1 =	the average of the Last Reported Sale Prices of the
ADSs (divided by the number of Ordinary Shares then represented by one ADS) over the 10 consecutive Trading-Day period
immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires.



 





The adjustment to the Conversion Rate under this Section 14.04(e)
shall be determined 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 but will be given effect immediately after the open of business on the
Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the
10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange
offer, references in this Section 14.04(e) with respect to 10 Trading Days shall be deemed to be replaced with such lesser number
of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date of such tender or exchange
offer to, and including, the Conversion Date in determining the Conversion Rate. For the avoidance of doubt, the references to
“Ordinary Shares” in “OS0” and “OS1” above include without limitation
both Class A Ordinary Shares and Class B Ordinary Shares.


 











    	69



    	 



    

 


(f) Except as stated herein, the Company
shall not adjust the Conversion Rate for the issuance of Ordinary Shares or ADSs, any securities convertible into or exchangeable
for Ordinary Shares or ADSs, or the right to purchase Ordinary Shares or ADSs or such convertible or exchangeable securities. Notwithstanding
the foregoing, if any Conversion Rate adjustment becomes effective as described in this Section 14.04, and a Holder that has converted
any Notes with a Conversion Date occurring on or after the date such Conversion Rate adjustment becomes effective will participate,
at the same time and upon the same terms as Holders of ADSs and solely as a result of holding the ADSs issuable upon conversion
of such Notes, in the transaction or event giving rise to such Conversion Rate adjustment, then such Conversion Rate adjustment
will not be made with respect to such Notes.


 


(g) 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 law and the rules of The New
York Stock Exchange or any other securities exchange on which any of the securities of the Company 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 (which determination shall be conclusive). In addition,
the Company may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Ordinary Shares
or ADSs or rights to purchase Ordinary Shares or ADSs in connection with a dividend or distribution of Ordinary Shares or ADSs
(or rights to acquire Ordinary Shares or ADSs) or similar event. Whenever the Conversion Rate is increased pursuant to either of
the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Note Register
a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state
the increased Conversion Rate and the period during which it will be in effect.


 


(h) Notwithstanding anything to the
contrary in this Article 14, the Conversion Rate shall not be adjusted:


 


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


 


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


 


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


 


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


 


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


 






    	70



    	 



    

 


(i) All calculations and other determinations
under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of an ADS. The
Company shall not be required to make an adjustment to the Conversion Rate unless the adjustment would require a change of at least
1% in the Conversion Rate. However, the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate
and make such carried-forward adjustments, regardless of whether the aggregate adjustment is less than 1%, on (x) December 31 of
each calendar year and (y) the Conversion Date for any conversion of Notes.


 


(j) Whenever the Conversion Rate is
adjusted as herein provided, the Company shall promptly notify the Trustee, the Conversion Agent and the Paying Agent of such adjustment
to the Conversion Rate and file with the Trustee, the Conversion Agent and the Paying Agent an Officers’ Certificate setting
forth the Conversion Rate after such adjustment and a brief statement of the facts requiring such adjustment, and the Trustee,
the Conversion Agent and the Paying Agent may conclusively rely on the accuracy of such adjustment to the Conversion Rate provided
by the Company in such Officers’ Certificate. Unless and until a Responsible Officer of the Trustee shall have received such
Officers’ Certificate, neither the Trustee, the Conversion Agent nor the Paying Agent shall be deemed to have knowledge of
any such adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has been notified
by the Company is still in effect. Promptly after providing such notice and delivery of such Officers’ Certificate to the
Trustee, the Conversion Agent and the Paying Agent, the Company shall prepare a notice of such adjustment of the Conversion Rate
setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail within 5 Business
Days of the date on which such adjustment of the Conversion Rate is made to each Holder at its last address appearing on the Note
Register of this Indenture. Failure by the Company to deliver such notice shall not affect the legality or validity of any such
Conversion Rate adjustment.


 


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


 


(l) Notwithstanding the foregoing, if
(1) an adjustment to the Conversion Rate in respect of any dividend or distribution described in this Section 14.04 does not become
effective prior to the Conversion Date for any Notes such that the relevant converting Holder receives, upon conversion, a number
ADSs that does not reflect such adjustment to the Conversion Rate, and (2) the Record Date in respect of the ADSs due upon conversion
for such dividend or distribution has occurred prior to the relevant Conversion Date, then, notwithstanding anything to contrary
herein, the Company shall pay or deliver to the relevant converting Holder, at the same time and upon the same terms as holders
of the ADSs, the dividend or distribution that such converting Holder would have received had it held, on such Record Date, a number
of ADSs equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes converted by such Holder.


 


Section
14.05          Adjustments
of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices (including
the ADS Prices for purposes of a Make-Whole Fundamental Change or a Tax Redemption) over a span of multiple days, the Board of
Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective,
or any event requiring an adjustment to the Conversion Rate where the Record Date of the event occurs, at any time during the
period when such Last Reported Sale Prices or ADS Prices are to be calculated.


 






    	71



    	 



    

 


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


 


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


 


(a) In the event of:


 


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


 


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


 


(iii) any sale, lease or other
transfer to another Person of all or substantially all of the property and assets of the Company; or


 


(iv) any statutory share exchange,


 


in each case, as a result of which the ADSs
would be converted into, or exchanged for, stock, other securities or other property or assets (including cash or any combination
thereof) (any such event, a “Merger Event”), then, 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 in such Merger Event) upon such Merger
Event and, 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 for such change in the
right to convert each US$1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger
Event the number of ADSs otherwise deliverable upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable
in the amount and type of Reference Property that a holder of that number of ADSs would have received in such Merger Event.


 


If the Merger Event causes the ADSs 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 stockholder 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 received by the holders of the ADSs that affirmatively make such
an election, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration
referred to in clause (i) attributable to one ADS. The Company shall notify 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.


 






    	72



    	 



    

 


Such supplemental indenture described in
the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the
adjustments provided for in this Article 14. 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 successor or purchasing
corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person
and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable
the provisions providing for the purchase rights set forth in Article 15.


 


(b) In the event the Company shall execute
a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company shall promptly file with the Trustee, the
Conversion Agent and the Paying Agent an Officers’ Certificate briefly stating the reasons therefore, the kind or amount
of cash, securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment
to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof
to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at
its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver
such notice shall not affect the legality or validity of such supplemental indenture.


 


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


 


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


 


Section
14.08          Certain
Covenants. (a) The Company covenants that all ADSs issued 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 Commission, secure such

Responsibility of Trustee. The Trustee, the Conversion Agent, the Paying Agent and any other Conversion Agent
other than Citibank, N.A. shall not at any time be under any duty or responsibility to any Holder to perform calculations or 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.
None of the Trustee, the Paying Agent nor the Conversion Agent shall be accountable with respect to the validity or value (or
the kind or amount) of any ADSs, or of any securities or other property, that may at any time be issued or delivered upon the
conversion of any Note; and the Trustee, the Paying Agent and the Conversion Agent make no representations with respect thereto
in this Indenture. None of the Trustee, the Paying Agent nor any Conversion Agent shall be responsible for any failure of the
Company to issue, transfer or deliver any ADSs, or the Class A Ordinary Shares represented thereby, or share certificates or other
securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Indenture. Without limiting the generality of the foregoing, none
of the Trustee, the Paying Agent nor any Conversion Agent shall be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount
of ADSs or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred
to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01,
may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture)
and Opinion of Counsel with respect thereto. None of the Trustee, the Paying Agent nor any Conversion Agent has any duty to determine
how or when any adjustment described in Section 14.04 should be made. None of the Trustee, the Paying Agent nor any Conversion
Agent shall be responsible for the failure of the Company to comply with this 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;


 


(b) Merger Event; or


 


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


 


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

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 issued upon
such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the ADSs
issued 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. If prior to any conversion, however, the rights have separated from
the Ordinary Shares in accordance with the provisions of the applicable stockholder rights plan so that converting Holders would
not be entitled to receive any rights in respect of ADSs issuable upon conversion of the Notes, the Conversion Rate shall be adjusted
at the time of separation as if the Company distributed Distributed Property to all holders of Ordinary Shares as provided in
Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.


 


Section
14.12         
Termination of Depositary Receipt Program. If the Class A Ordinary Shares cease to be represented by American
Depositary Shares issued under a depositary receipt program sponsored by the Company, all references in this Indenture to the
ADSs shall be deemed to have been replaced by a reference to the number of 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.

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

The Paying Agent shall promptly notify the

TAX REDEMPTION


 


Section
16.01          Redemption
for Taxation Reasons


 


If as a result of any change in or amendment
to the statutes (or any rules or regulations thereunder) of a Relevant Taxing Jurisdiction, or any amendment to or change in an
official interpretation, administration or application of such statutes, rules or regulations (including a holding by a court of
competent jurisdiction), which change or amendment becomes effective or, in the case of a change in official interpretation, is
announced on or after August 6, 2014 or, if the Relevant Taxing Jurisdiction has changed after August 6, 2014, the date on which
such change occurred, the Company or its successor is, or will become, obligated to pay Additional Amounts as described under Section
4.07, the Company or its successor may, at its option, redeem all, but not less than all, of the Notes, for cash at a price (the
“Tax Redemption Price”) equal to 100% of their principal amount, together with accrued and unpaid interest to,
but excluding, the Tax Redemption Date and Additional Amounts, if any, upon giving irrevocable notice in writing to each of the
Holder of Notes not less than 20 calendar days nor more than 60 calendar days prior to the Tax Redemption Date (the “Tax
Redemption Notice” and such redemption, a “Tax Redemption”). However, if the Tax Redemption Date occurs
after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company will pay the full amount of
accrued and unpaid interest due on such payment date to the record Holder on the Regular Record Date corresponding to such Interest
Payment Date, and the Tax Redemption Price payable to the Holder who presents the Note for redemption will be 100% of the principal
amount of such Note and Additional Amounts, if any. No Tax Redemption Notice may be given earlier than 60 calendar days prior to
the earliest date on which the Company or any such successor would, but for such Tax Redemption, be obligated to pay the Additional
Amounts. Notwithstanding the foregoing, the Company or any such successor shall not have the right to so redeem the Notes unless
it has taken reasonable measures to avoid the obligation to pay Additional Amounts.


 






    	81



    	 



    

 


In the event that the Company or any successor
elects to so redeem the notes, it shall deliver to the Trustee: (1) a certificate, signed in the Company’s name or its successor’s
name by any two of its executive officers stating that it is entitled to redeem the Notes pursuant to their terms and setting forth
a statement of facts showing that the condition or conditions precedent to its right or the right of any successor to so redeem
have occurred or been satisfied including, that it cannot avoid payment of such Additional Amounts by taking reasonable measures
available to it and that all governmental requirements necessary for the Company or any successor to effect the redemption have
been complied with; and (2) an Opinion of Counsel, who is acceptable to the Trustee, to the effect that the Company or its successor
has or will become obligated to pay Additional Amounts as a result of the change or amendment.


 


Notwithstanding the foregoing, if the Company
or its successor has given a Tax Redemption Notice, each Holder of Notes shall have the right to elect that such Holder’s
Notes will not be subject to such Tax Redemption. If a Holder elects not to be subject to a Tax Redemption, the Company or its
successor will not be required to pay Additional Amounts with respect to payments made in respect of such Holder’s Notes
following the Tax Redemption Date, and all subsequent payments in respect of such Holder’s Notes will be subject to any tax
required to be withheld or deducted under the laws of a Relevant Taxing Jurisdiction. The obligation to pay Additional Amounts
to any electing Holder for periods up to the Tax Redemption Date will remain subject to the exceptions set forth under Section
4.07. Holders must exercise their option to elect to avoid a Tax Redemption by written notice to the Trustee no later than the
15th calendar day prior to the Tax Redemption Date.


 


In the case of such Tax Redemption, Holders
shall have the right to elect to convert the Notes at any time until the close of business on the second Business Day preceding
the Tax Redemption Date.


 


Section
16.02               
Effect of Tax Redemption Notice


 


The Tax Redemption Notice having been given
as provided in Section 16.01 hereof, the Notes to be redeemed shall, on the Tax Redemption Date, become due and payable at the
Tax Redemption Price therein specified, and from and after such date (unless the Company shall Default in the payment of the Tax
Redemption Price and any interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance
with such Tax Redemption Notice, such Note shall be paid by the Company at the Tax Redemption Price.


 


If any Note called for redemption shall
not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Tax Redemption Date.


 






    	82



    	 



    

 


Section
16.03               
Deposit and Payment of Tax Redemption Price


 


Not later than 10:00 a.m. New York time
on the Business Day prior to any Tax Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent an amount
of money in immediately available funds sufficient to pay the Tax Redemption Price and interest in respect of all the Notes to
be redeemed on that Tax Redemption Date from the last Interest Payment Date to but not including the Tax Redemption Date, other
than any Notes called for redemption on that date which have been converted prior to the date of such deposit, and accrued and
unpaid interest on such Notes. The Trustee and Paying Agent shall then cause such funds to be paid to the Holders of the Notes
being redeemed in accordance with this Article 16.


 


If any Note delivered for redemption shall
not be so redeemed by payment to the Holders thereof on the Tax Redemption Date, the principal amount of such Note shall, until
it is redeemed, bear interest on the Tax Redemption Date to but not including the actual date of redemption at the applicable interest
rate, and each such Note shall remain convertible into ADSs pursuant to Article 14 until such Note shall have been so redeemed.


 


If any Note called for redemption is converted,
any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Note
shall be paid to the Company upon request by the Company or, if then held by the Company, shall be discharged from such trust.

[FORM OF REVERSE OF NOTE]


 


QIHOO 360 TECHNOLOGY
CO. LTD.


 


0.50% Convertible Senior
Note due 2020


 


This Note is one of a duly authorized issue
of Notes of the Company, designated as its 0.50% Convertible Senior Notes due 2020 (the “Notes”), limited to
the aggregate principal amount of US$450,000,000 all issued under and pursuant to an Indenture dated as of August 6, 2014 (the
“Indenture”), between the Company and Citicorp International Limited (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 an Event 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.


 


Subject to the terms and conditions of the
Indenture, the Company will make all payments and deliveries in respect of the Tax Redemption Price, the Repurchase Price, the
Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders
a Note to a Paying Agent 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, exceptions and conditions
of the Indenture, in the event any withholding or deduction of taxes, duties, assessments or governmental charges is imposed or
levied by a Relevant Taxing Jurisdiction in connection with any payments and deliveries 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, payments
of interest and deliveries of ADSs (together with cash payments in lieu of any fractional ADSs) upon conversion, Additional Amounts
will be paid to ensure that the net amount received by the beneficial owner after any applicable withholding or deduction (and
after deducting any taxes on the Additional Amounts) will equal the amount that would have been received by such beneficial owner
had no such withholding or deduction been required. References to principal, interest or deliveries of ADSs (together with cash
payments in lieu of any fractional ADSs) in respect of the Notes shall be deemed also to refer to any Additional Amounts which
may be payable.


 


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.


 






    	A-6



    	 



    

 


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 the principal (including the Tax Redemption Price, the Repurchase Price and the Fundamental Change Repurchase Price, if
applicable) of and accrued and unpaid interest on this Note at the place, at the respective times, at the rate and in the lawful
money herein prescribed.


 


The Notes are issuable in registered form
without coupons in minimum denominations of US$200,000 principal amount and integral multiples of US$1,000 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 documentary, stamp or
similar issue or transfer taxes, if any, 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.


 


Subject to the terms and conditions of the
Indenture, the Notes may only be redeemed, in whole but not in part, at the Company’s option, at a redemption price equal
to 100% of the aggregate principal amount of the Notes to be redeemed, plus accrued interest to, but excluding, the Tax Redemption
Date, if, as a result of any change in, or amendment to, the statutes (or any rules or regulations thereunder) of a Relevant Taxing
Jurisdiction or any amendment to or change in an official interpretation, administration or application of such statutes, rules
or regulations (including a holding by a court of competent jurisdiction), which change or amendment becomes effective or, if in
the case of a change in official interpretation, is announced on or after August 6, 2014 or, if the Relevant Taxing Jurisdiction
has changed after August 6, 2014, the date on which such change occurred, the Company is, or its successor, is, or would be, obligated
on the next succeeding due date to pay Additional Amounts and such obligation cannot be avoided by the use of reasonable measures
available to the Company or its successor in accordance with the Indenture.


 


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


 


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


 


Subject to the provisions of the Indenture,
the Holder hereof has the right, at its option, prior to the close of business on the third Business Day immediately preceding
the Maturity Date, to convert any Notes or portion thereof that is US$1,000 or an integral multiple thereof, into ADSs at the Conversion
Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.


 


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