(a) the Memorandum or these Articles;

(b) the designations, powers, preferences, rights, qualifications, limitations and restrictions with which the shares were issued; or

24. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not be deemed to be varied by the creation or issuance of further shares ranking pari passu therewith.

For the purpose of establishing whether or not a foreign court had competent jurisdiction in such a matter the directors may obtain appropriate legal advice. The directors may also require an indemnity to be given by the executor, administrator, guardian or trustee in bankruptcy.

27. Any person becoming entitled by operation of law or otherwise to a share or shares in consequence of the death, incompetence or bankruptcy of any member may be registered as a member upon such evidence being produced as may reasonably be required by the directors.

28. Any person who has become entitled to a share or shares in consequence of the death, incompetence or bankruptcy of any member may, instead of being registered himself, request in writing that some person to be named by him be registered as the transferee of such share or shares and such request shall likewise be treated as if it were a transfer.

29. What amounts to incompetence on the part of a person is a matter to be determined by the court having regard to all the relevant evidence and the circumstances of the case.

The conversion rate for each Preferred Share shall be determined by dividing the applicable Preferred Share Issue Price by the applicable conversion price then in effect at the date of the conversion. The initial conversion price for each Preferred Share will be the applicable Preferred Share Issue Price (i.e., a 1-to-1 initial conversion ratio), each of which will be subject to adjustments to reflect stock dividends, stock splits and other events, as provided in Article 39 below (each, a “Preferred Share Conversion Price”). The conversion rate for Class B Ordinary Shares shall be 1-to-1, as adjusted for share dividends, splits, combinations, recapitalizations or similar events and are otherwise, provided herein.

Nothing in this Article 35 shall limit the automatic conversion rights of Preferred Shares described in Article 36A below and nothing in this Article 35 shall limit the automatic conversion of Class B Ordinary Shares described in Article 36B below.

36A. Automatic Conversion. Each Preferred Share shall automatically be converted into Class A Ordinary Shares, at the then applicable Preferred Share Conversion Price (i) upon the closing of an underwritten public offering of the Class A Ordinary Shares of the Company in the United States, that has been registered under the Securities Act of 1933, as amended (the “Securities Act”), or in a similar public offering of the Class A Ordinary Shares of the Company in Hong Kong or another jurisdiction which results in the Class A Ordinary Shares trading publicly on a recognized international securities exchange (an “Initial Public Offering”) or in the event that a majority of the issued and outstanding share capital of the Company or a majority of the voting power of the Company is acquired by a listed company of the aforementioned securities exchanges via issuance of new stocks whereby the Control of such listed company is acquired by the Company (a “Listed Company’s Acquisition”); provided that such offering in terms of regulatory approval is reasonably equivalent to the aforementioned public offering in the United States and such offering or acquisition is subject to the prior written approval of the holders of Preferred Shares, provided that the Preferred Share Conversion Price for Series D Preferred Shares shall be adjusted in accordance with Article 39(j) immediately prior to such Initial Public Offering or Listed Company’s Acquisition, if applicable, or(ii) with respect to the Series A Preferred Shares and Series B-1 Preferred Shares, upon the prior written approval of the holders of the shares carrying at least a majority of the voting power of the then outstanding Series A Preferred Shares and Series B-1 Preferred Shares; with respect to Series B-2 Preferred Shares, upon the prior written approval of the holders of at least a majority of the then outstanding Series B-2 Preferred Shares; with respect to Series C Preferred Shares, upon the prior written approval of the holders of the shares carrying at least a majority of the voting power of the then outstanding Series C Preferred Shares; with respect to Series C+ Preferred Shares, upon the prior written approval of the holders of at least a majority of the then outstanding Series C+ Preferred Shares; with respect to Series C-4 Preferred Shares, upon the prior written approval of the holders of the shares carrying at least a majority of the voting power of the then outstanding Series C-4 Preferred Shares; and with respect to Series D Preferred Shares, upon the prior written approval of the holders of the shares carrying at least a majority of the voting power of the then outstanding Series D Preferred Shares. In the event of the automatic conversion of the Preferred Shares upon an Initial Public Offering or Listed Company’s Acquisition as aforesaid, the person(s) entitled to receive the Class A Ordinary Shares issuable upon such conversion of Preferred Shares shall not be deemed to have converted such Preferred Shares until immediately prior to the closing of such Initial Public Offering or Listed Company’s Acquisition (as applicable).

36B. Automatic Conversion of Class B Ordinary Shares. Each Class B Ordinary Share shall automatically be converted into Class A Ordinary Shares, at the then applicable conversion rate with respect to the Class A Ordinary Shares (i) upon the prior written approval of the holders of the shares carrying at least a majority of the voting power of the then outstanding Class B Ordinary Shares; or (ii) upon any sale, transfer, assignment or disposition of any Class B Ordinary Share by the holder thereof or an Affiliate or such holder to any person who is not an Affiliate of such holder, such Class B Ordinary Share shall be automatically and immediately converted into one Class A Ordinary Share. For the avoidance of doubt, (i) a sale, transfer, assignment or disposition shall be effective upon the Company’s registration of such sale, transfer, assignment or disposition in its Register of Members; and (ii) the creation of any pledge, charge, encumbrance or other third party right of whatever description on any Class B Ordinary Shares to secure a holder’s contractual or legal obligations shall not be deemed as a sale, transfer, assignment or disposition unless and until any such pledge, charge, encumbrance or other third party right is enforced and results in the third party holding legal title to the relevant Class B Ordinary Shares, in which case all the related Class B Ordinary Shares shall be automatically converted into the same number of Class A Ordinary Shares.

14

37. Mechanics of Conversion. No fractional Ordinary Share shall be issued upon conversion of the Preferred Shares, and in lieu of any fractional share to which the holder would otherwise be entitled after first aggregating all fractional shares that such holder would otherwise receive, the Company shall pay cash equal to such fraction multiplied by the then effective Preferred Share Conversion Price. Before any holder of Preferred Shares and/or Class B Ordinary Shares shall be entitled to convert the same into full Class A Ordinary Shares and to receive certificates therefor, he shall surrender the certificate or certificates therefor, at the office of the Company or of any transfer agent for the Preferred Shares and/or Class B Ordinary Shares and shall give written notice to the Company at such office that he elects to convert the same. The Company shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Preferred Shares and/or Class B Ordinary Shares a certificate or certificates for the number of Class A Ordinary Shares to which he shall be entitled as aforesaid and a check payable to the holder in the amount of any cash amounts payable as the result of a conversion into fractional Class A Ordinary Shares, if any. Such conversion shall be deemed to have been made immediately prior to close of business on the date of such surrender of the shares of Preferred Shares and/or Class B Ordinary Shares to be converted, and the person or persons entitled to receive the Class A Ordinary Shares issuable upon such conversion shall be treated for all purposes as the record holder or holders of such Class A Ordinary Shares on such date after its name is recorded in the Register of Members as the holder of such Class A Ordinary Shares. The Directors may effect conversion in any matter permitted by law including, without prejudice to the generality of the foregoing, repurchasing or redeeming the relevant Preferred Shares and applying the proceeds towards the issue of the relevant number of new Class A Ordinary Shares.

38. Reservation of Shares Issuable Upon Conversion. The Company shall at all times reserve and keep available out of its authorized but unissued Class A Ordinary Shares solely for the purpose of effecting the conversion of the shares of the Preferred Shares and/or Class B Ordinary Shares such number of its Class A Ordinary Shares as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Preferred Shares and/or Class B Ordinary Shares, and if at any time the number of authorized but unissued Class A Ordinary shares shall not be sufficient to effect the conversion of all then outstanding shares of the Preferred Shares and/or Class B Ordinary Shares, in addition to such other remedies as shall be available to the holder of such Preferred Shares and/or Class B Ordinary Shares, the Company will take such corporate action as may, in the opinion of its legal counsel, be necessary to increase its authorized but unissued Class A Ordinary Shares to such number of shares as shall be sufficient for such purposes.

ADJUSTMENTS TO PREFERRED SHARE CONVERSION PRICE

(E) any securities issued pursuant to an Initial Public Offering or a Listed Company’s Acquisition;

(b) No Adjustment to Conversion Price. No adjustment in a Preferred Share Conversion Price shall be made in respect of the issuance of Additional Ordinary Shares unless the consideration per share for an Additional Ordinary Share issued or deemed to be issued by the Company is less than such Preferred Share Conversion Price in effect on the date of and immediately prior to such issuance.

(c) Deemed Issuance of Additional Ordinary Shares. In the event the Company at any time or from time to time after the Original Issue Date of a class or series of Preferred Shares shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number that would result in an adjustment pursuant to clause (ii) below) of Ordinary Shares issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Ordinary Shares issued as of the time of such issuance or, in case such a record date shall have been fixed, as of the close of business on such record date, provided that in any such case in which Additional Ordinary Shares are deemed to be issued:

(i) no further adjustment to a Preferred Share Conversion Price shall be made upon the subsequent issuance of Convertible Securities or Ordinary Shares upon the exercise of such Options or conversion or exchange of such Convertible Securities;

16

(ii) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to the Company, or increase or decrease in the number of Ordinary Shares issuable, upon the exercise, conversion or exchange thereof, a Preferred Share Conversion Price computed upon the original issuance thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

(iii) upon the expiration of any such Options or any rights of conversion or exchange under such Convertible Securities which shall not have been fully exercised, a Preferred Share Conversion Price computed upon the original issuance thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration be recomputed as if:

(A) in the case of Convertible Securities or Options for Ordinary Shares, the only Additional Ordinary Shares issued were Ordinary Shares, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Company for the issuance of all such Options, whether or not exercised, plus the consideration actually received by the Company upon such exercise, or for the issuance of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Company upon such conversion or exchange, and

(B) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issuance of such Options, and the consideration received by the Company for the Additional Ordinary Shares deemed to have been then issued was the consideration actually received by the Company for the issuance of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Company upon the issuance of the Convertible Securities with respect to which such Options were actually exercised;

(iv) no readjustment pursuant to clause (ii) or (iii) above shall have the effect of increasing the Preferred Share Conversion Price to an amount which exceeds the lower of (i) the Preferred Share Conversion Price immediately prior to the original adjustment date, or (ii) the Preferred Share Conversion Price that would have resulted from any issuance of Additional Ordinary Shares between the original adjustment date and such readjustment date; and

(v) in the case of any Options which expire by their terms not more than 30 days after the date of issuance thereof, no adjustment of the Preferred Share Conversion Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the manner provided in clause (iii) above.

17

(d) Adjustment of Preferred Share Conversion Price upon Issuance of Additional Ordinary Shares below the Preferred Share Conversion Price. In the event that the Company shall issue any Additional Ordinary Shares (including those deemed to be issued pursuant to Article 39 (c)) without consideration or at a subscription price per Ordinary Share (on an as-converted basis) less than the Preferred Share Conversion Price for any class or series of Preferred Shares as in effect on the date of and immediately prior to such issuance, then the Preferred Share Conversion Price for such Preferred Shares shall be reduced, concurrently with such issuance, to a price equal to a price per share (calculated to nearest cent) determined in accordance with the following formula:

CP2=CP1×[(A+B)÷(A+C)]

For purpose of the foregoing formula, the following definitions shall apply:

“CP2” means the applicable Preferred Share Conversion Price in effect for such Preferred Shares immediately after such issue of Additional Ordinary Shares;

“CP1” means the applicable Preferred Share Conversion Price in effect for such Preferred Shares immediately prior to such issue of Additional Ordinary Shares;

“A” means the number of Ordinary Shares Outstanding immediately prior to such issue of Additional Preferred Shares;

“B” means the number of Ordinary Shares that would have been issued if such Additional Ordinary Shares had been issued at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the Company in respect of such issue by CP1), and;

“C” means the number of such Additional Ordinary Shares issued in such transaction.

For purposes of this Article, the term “Ordinary Shares Outstanding” shall mean and include the following: (1) outstanding Ordinary Shares, (2) Ordinary Shares issuable upon conversion of outstanding Preferred Shares, (3) Ordinary Shares issuable upon exercise of outstanding share options, and (4) Ordinary Shares issuable upon exercise (and, in the case of warrants to purchase Preferred Shares, conversion) of outstanding warrants. Shares described in (1) through (4) above shall be included whether vested or unvested, whether contingent or non-contingent and whether exercisable or not yet exercisable.

(e) Determination of Consideration. For purposes of this Article 39, the consideration received by the Company for the issuance of any Additional Ordinary Shares shall be computed as follows:

(i) Cash and Property. Except as provided in clause (ii) below, such consideration shall:

(A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Company excluding amounts paid or payable for accrued interest for accrued dividends;

(B) insofar as it consists of property other than cash, be computed at the fair value thereof at the time of such issuance, as determined in good faith by the Board; provided, however, that no value shall be attributed to any services performed by any employee, officer or director of the Company; and

18

(C) in the event Additional Ordinary Shares are issued together with other shares or securities or other assets of the Company for consideration which covers both, be the proportion of such consideration so received with respect to such Additional Ordinary Shares, computed as provided in clauses (A) and (B) above, as determined in good faith by the Board.

(ii) Options and Convertible Securities. The consideration per share received by the Company for Additional Ordinary Shares deemed to have been issued pursuant to Article 39(c), relating to Options and Convertible Securities, shall be determined by dividing

(A) the total amount, if any, received or receivable by the Company as consideration for the issuance of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities by

(B) the maximum number of Ordinary Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.

(f) Adjustments for Share Dividends, Subdivisions, Combinations or Consolidations of Ordinary Shares. In the event the outstanding Ordinary Shares shall be subdivided (by share dividend, share split, or otherwise), into a greater number of Ordinary Shares, each Preferred Share Conversion Price shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In the event the outstanding Ordinary Shares shall be combined or consolidated, by reclassification or otherwise, into a lesser number of Ordinary Shares each Preferred Share Conversion Price shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased.

(g) Adjustments for Other Distributions. In the event the Company at any time or from time to time makes, or files a record date for the determination of holders of Ordinary Shares entitled to receive any distribution payable in securities or assets of the Company other than Ordinary Shares, then and in each such event provision shall be made so that the holders of Preferred Shares shall receive upon conversion thereof, in addition to the number of Ordinary Shares receivable thereupon, the amount of securities or assets of the Company which they would have received had their Preferred Shares been converted into Ordinary Shares on the date of such event and had they thereafter, during the period from the date of such event to and including the date of conversion, retained such securities or assets receivable by them as aforesaid during such period, subject to all other adjustment called for during such period under this Article 39 with respect to the rights of the holders of the Preferred Shares.

19

(h) Adjustments for Reclassification, Exchange and Substitution. If the Ordinary Shares issuable upon conversion of the Preferred Shares shall be changed into the same or a different number of shares of any other class or classes of shares, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares provided for above), then and in each such event the holder of each share of Preferred Shares shall have the right thereafter to convert such share into the kind and amount of shares and other securities and property receivable upon such reorganization or reclassification or other change by holders of the number of Ordinary Shares that would have been subject to receipt by the holders upon conversion of the Preferred Shares immediately before that change, all subject to further adjustment as provided herein.

(i) Other Dilutive Events. In case any event shall occur as to which the other provisions of this Article 39 are not strictly applicable, but the failure to make any adjustment to the applicable Preferred Share Conversion Price for the Preferred Shares would not fairly protect the conversion rights of such Preferred Shares in accordance with the essential intent and principles hereof, then, in each such case, the Company, in good faith, shall determine the appropriate adjustment to be made, on a basis consistent with the essential intent and principles established in this Article 39, necessary to preserve, without dilution, the conversion rights of the Preferred Shares. If any holder of the then outstanding Preferred Shares shall reasonably and in good faith disagree with such determination by the Company, then the Company shall appoint an accounting firm of international standing and reputation agreeable to the holders of such Preferred Shares, which shall give their opinion as to the appropriate adjustment, if any, on the basis described above. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the holders of such Preferred Shares and shall make the adjustments described therein.

(j) Special Adjustment for Series D Preferred Shares. Notwithstanding the forgoing,

(A) in the event that the money-valuation of the Company in connection with or immediately prior to Initial Public Offering is less than US$1,000,000,000, then

(a) the Preferred Share Conversion Price for the Series D-2 Preferred Shares shall be reduced, to a price equal to a price per share (calculated to nearest cent) determined in accordance with the following formula:

CP2=CP1×(B÷A)

For purpose of the foregoing formula, the following definitions shall apply:

“CP2” means the applicable Preferred Share Conversion Price in effect for such Series D-2 Preferred Shares immediately after such adjustment;

“CP1” means the applicable Preferred Share Conversion Price in effect for such Series D-2 Preferred Shares immediately prior to such adjustment;

“B” means (i) 75% of the money-valuation of the Company immediately prior to Initial Public Offering, or (ii) the Post Money-Valuation of Series D-2, whichever is lower. For purpose of this Agreement, the “Post Money-Valuation of Series D-2” means US$ 702,300,000;

“A” means the applicable Post Money-Valuation of Series D-2.

20

(b) the Preferred Share Conversion Price for the Series D-1 Preferred Shares shall be reduced, to a price equal to a price per share (calculated to nearest cent) determined in accordance with the following formula:

CP3=CP2×(US$623,350,000÷US$650,000,000)

For purpose of the foregoing formula, the following definitions shall apply:

“CP3” means the applicable Preferred Share Conversion Price in effect for such Series D-1 Preferred Shares immediately after such adjustment;

(B) in the event that the money-valuation of the Company immediately prior to Initial Public Offering is less than US$600,000,000, then

(a) the Preferred Share Conversion Price for the Series D-2 Preferred Shares shall be reduced, to a price equal to a price per share (calculated to nearest cent) determined in accordance with the following formula:

CP2=CP1×(C÷A)

For purpose of the foregoing formula, the following definitions shall apply:

“CP2” means the applicable Preferred Share Conversion Price in effect for such Series D-2 Preferred Shares immediately after such adjustment;

“CP1” means the applicable Preferred Share Conversion Price in effect for such Series D-2 Preferred Shares immediately prior to such adjustment;

“C” means 80% of the money-valuation of the Company immediately prior to Initial Public Offering;

“A” means the Post Money-Valuation of Series D-2.

(b) the Preferred Share Conversion Price for the Series D-1 Preferred Shares shall be reduced, to a price equal to a price per share (calculated to nearest cent) determined in accordance with the following formula:

CP3=CP2×(US$623,350,000÷US$650,000,000)

For purpose of the foregoing formula, the following definitions shall apply:

“CP3” means the applicable Preferred Share Conversion Price in effect for such Series D-1 Preferred Shares immediately after such adjustment;

(k) No Impairment. The Company will not, by the amendment of its Memorandum and Articles of Association or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of Article 39 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Preferred Shares against impairment.

21

(l) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to Article 39, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Preferred Shares a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any holder of Preferred Shares, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Preferred Share Conversion Price for such Preferred Shares at the time in effect, and (iii) the number of Ordinary Shares and the amount, if any, of other property which at the time would be received upon the conversion of such Preferred Shares.

(m) Miscellaneous.

(iii) No adjustment in the Preferred Share Conversion Price need be made if such adjustment would result in a change in such conversion price of less than US$0.01. Any adjustment of less than US$0.01 which is not made shall be carried forward and shall be made at the time of and together with any subsequent adjustment which, on a cumulative basis, amounts to an adjustment of US$0.0l or more in such conversion price.

VOTING RIGHTS

40. Each Preferred Share shall carry a number of votes equal to the number of Class A Ordinary Shares then issuable upon its conversion into Class A Ordinary Shares at the record date for determination of the shareholders entitled to vote on such matters, or, if no such record date is established, at the date such vote is taken or any written consent of shareholders is solicited. To the extent that applicable law, the Memorandum and/or these Articles require the Preferred Shares to vote separately as a class with respect to any matters, or with respect to any matters provided in Article 41, the Preferred Shares shall vote separately as a class with respect to such matters. Otherwise, the holders of Preferred Shares and Ordinary Shares shall vote together as a single class.
