7B(2). A forfeited share may be resold or otherwise disposed of on such terms and in such manner as the Directors think fit, and at any time before a sale or disposition, the forfeiture may be cancelled on such terms as the Directors see fit.

7B(3). A person whose shares have been forfeited shall cease to be a Member in respect of the forfeited shares, but shall, notwithstanding, remain liable to pay to the Company all monies which, at the date of forfeiture, were payable by him to the Company in respect of the shares together with interest thereon, but this liability shall cease if and when the Company shall have received payment in full of all monies whenever payable in respect of the shares.

7B(4). A certificate in writing under the hand of one Director or the Secretary of the Company that a share in the Company has been duly forfeited on a date stated in the declaration shall be conclusive evidence of the fact therein stated as against all persons claiming to be entitled to the share. The certificate shall (subject to the execution of an instrument of transfer) constitute good title to the share and the person to whom the share is resold or disposed of shall thereupon be registered as the holder of the share and shall not be bound to see to the application of the purchase money, if any, nor shall his title to the share be affected by any irregularity or invalidity in the proceedings in reference to the forfeiture, sale or disposal of the share.

7B(5). The provisions of these Articles as to forfeiture shall apply in the case of non-payment of any sum which, by the terms of issue of a share, becomes payable at a fixed time, whether on account of the nominal value of the share or by way of premium as if the same had been payable by virtue of a call duly made and notified.

REDEMPTION AND PURCHASE OF SHARES

8. (i) Subject to the provisions of the Statute, the Memorandum and these Articles (including without limitation Schedule A), shares may be issued on the terms that they are, or at the option of the Company or the holder are, to be redeemed on such terms and in such manner as the Company, before the issue of the shares, may by Special Resolution determine.

(ii) Subject to the provisions of the Statute, the Memorandum and these Articles (including without limitation Schedule A), the Company may purchase its own shares

VARIATION OF RIGHTS OF SHARES

9. Subject to Schedule A, if at any time the share capital of the Company is divided into different classes or series of shares, the rights attached to any class or series (unless otherwise provided by the terms of issue of the shares of that class or series) may not, whether or not the Company is being wound-up, be varied without the consent in writing of the holders of at least a majority of the issued shares of that class or series (voting on an as-if-converted and as-exercised basis), or without the sanction of a Special Resolution passed at a general meeting of the holders of the shares of that class or series (voting on an as-if-converted and as-exercised basis).

The provisions of these Articles relating to general meetings shall apply to every such general meeting of the holders of one class of shares except that the necessary quorum shall be one (1) person holding, or representing by proxy, at least a majority of the issued shares of the class (voting on an as-if-converted and as-exercised basis) and that any holder of shares of the class present in person or by proxy may demand a poll.

10. Subject to Schedule A, the rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith.

TRANSMISSION OF SHARES

14. In case of the death of a Member, the survivor or survivors where the deceased was a joint holder, and the legal personal representatives of the deceased where he was a sole holder, shall be the only persons recognized by the Company as having any title to his interest in the shares, but nothing herein contained shall release the estate of any such deceased holder from any liability in respect of any shares which had been held by him solely or jointly with other persons.

15. Any person becoming entitled to a share in consequence of the death or bankruptcy or liquidation or dissolution of a Member (or in any other way than by transfer) may, upon such evidence being produced as may from time to time be required by the Directors and, subject as hereinafter provided, elect either to be registered himself as holder of the share or to make such transfer of the share to such other person nominated by him as the deceased or bankrupt person could have made and to have such person registered as the transferee thereof, but the Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the share by that Member before his death or bankruptcy as the case may be. If the person so becoming entitled shall elect to be registered himself as holder, such person shall deliver or send to the Company a notice in writing signed by such person so stating such election.

16. A person becoming entitled to a share by reason of the death or bankruptcy or liquidation or dissolution of the holder (or in any other case than by voluntary transfer) shall be entitled to

the same dividends and other advantages to which he would be entitled if he were the registered holder of the share, except that he shall not, before being registered as a Member in respect of the share, be entitled in respect of it to exercise any right conferred by membership in relation to meetings of the Company; provided that the Directors may at any time give notice requiring any such person to elect either to be registered himself or to transfer the share and if the notice is not complied with within ninety days the Directors may thereafter withhold payment of all dividends, bonuses or other monies payable in respect of the share until the requirements of the notice have been complied with.

19. If no record date is fixed for the determination of Members entitled to notice of or to attend or vote at a meeting of Members or Members entitled to receive payment of a dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the Directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of Members.

Subject to the Statute and the provisions of these Articles (including but not limited to Schedule A), the Directors may from time to time declare dividends (including interim dividends) and distributions on shares of the Company outstanding and authorize payment of the same out of the funds of the Company lawfully available therefor.

77. Subject to the Statute and the provisions of these Articles (including but not limited to Schedule A), the Directors may, before declaring any dividends or distributions, set aside such sums as they think proper as a reserve or reserves which shall at the discretion of the Directors, be applicable for any purpose of the Company and pending such application may, at the like discretion, be employed in the business of the Company.

78. No dividend or distribution shall be payable except out of the profits of the Company, realized or unrealized, or out of the share premium account or as otherwise permitted by the Statute.

79. Subject to the rights of persons, if any, with shares with special rights as to dividends or distributions, if dividends or distributions are to be declared on a class of shares they shall be declared and paid according to the amounts paid or credited as paid on the shares of such class outstanding on the record date for such dividend or distribution as determined in accordance with these Articles but no amount paid or credited as paid on a share in advance of calls shall be treated for the purpose of this Article 79 as paid on the share.

80. The Directors may deduct from any dividend or distribution payable to any Member all sums of money (if any) presently payable by him to the Company on account of calls or otherwise.

81. Subject to these Articles (including but not limited to Schedule A), the Directors may declare that any dividend or distribution be paid wholly or partly by the distribution of specific assets and in particular of paid up shares or Debentures of any other company or in any one or more of such ways and where any difficulty arises in regard to such distribution, the Directors may settle the same as they think expedient and in particular may issue fractional certificates and fix the value for distribution of such specific assets or any part thereof and may determine that cash payments shall be made to any Members upon the footing of the value so fixed in order to adjust the rights of all Members and may vest any such specific assets in trustees as may seem expedient to the Directors.

82. Any dividend, distribution, interest or other monies payable in cash in respect of shares may be paid by check or warrant sent through the post directed to the registered address of the holder or, in the case of joint holders, to the holder who is first named on the register of Members or to such person and to such address as such holder or joint holders may in writing direct. Every such check or warrant shall be made payable to the order of the person to whom it is sent. Any one of two or more joint holders may give effectual receipts for any dividends, bonuses, or other monies payable in respect of the share held by them as joint holders.

83. No dividend or distribution shall bear interest against the Company.

CAPITALIZATION

84. Subject to these Articles (including but not limited to Schedule A), upon the recommendation of the Board, the Members may by Special resolution authorize the Directors to capitalize any sum standing to the credit of any of the Company’s reserve accounts (including share premium account and capital redemption reserve fund) or any sum standing to the credit of profit and loss account or otherwise available for distribution and to appropriate such sum to Members in the proportions in which such sum would have been divisible amongst them had

the same been a distribution of profits by way of dividend and to apply such sum on their behalf in paying up in full unissued shares for allotment and distribution credited as fully paid up to and amongst them in the proportion aforesaid. In such event the Directors shall do all acts and things required to give effect to such capitalization, with full power to the Directors to make such provisions as they think fit for the case of shares becoming distributable in fractions (including provisions whereby the benefit of fractional entitlements accrue to the Company rather than to the Members concerned). Subject to these Articles (including but not limited to Schedule A), the Directors may authorize any person to enter into, on behalf of all of the Members interested, an agreement with the Company providing for such capitalization and matters incidental thereto and any agreement made under such authority shall be effective and legally binding on all concerned.

85. The Directors shall cause proper books of account to be kept with respect to:

(a) All sums of money received and expended by the Company and the matters in respect of which the receipt or expenditure takes place;

(b) All sales and purchases of goods by the Company; and

(c) The assets and liabilities of the Company.

86. Subject to any agreement binding on the Company, the Directors shall from time to time determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of the Company or any of them shall be open to the inspection of Members not being Directors, and no Member (not being a Director) shall have any right of inspecting any account or book or document of the Company except as conferred by Statute or authorized by the Company.

89. Every Auditor of the Company shall have a right of access at all times to the books and accounts and vouchers of the Company and shall be entitled to require from the Directors and officers of the Company such information and explanation as may be necessary for the performance of the duties of the Auditors.

90. Auditors shall, following their appointment and at any other time during their term of office, upon request of the Directors, make a report on the accounts of the Company during their tenure of office.

SCHEDULE A

The holders of Preferred Shares and Ordinary Shares shall, in addition to any other rights conferred on them under the Memorandum and these Articles, have the rights set out in this Schedule A, which forms part of these Articles. In the event of any inconsistency between the provisions set out herein and other provisions of the Memorandum and these Articles, the provisions set out herein shall prevail to the extent permitted by applicable laws.

1. Dividends

(a) Subject to the provisions of the Statute and these Articles (including but not limited to the other requirements of this Schedule A), no dividends or distribution, whether in cash, in property, or in any other shares of the Company, shall be declared, paid, set aside or made with respect to the Ordinary Shares or any other class of shares of the Company at any time unless and until (i) all declared but unpaid dividends on the Preferred Shares set forth in Section (1)(b) of Schedule A have been paid in full, and (ii) a dividend or distribution in like amount is declared, paid, set aside or made on each issued and outstanding Preferred Share (on an as-if-converted basis), such that the dividend or distribution declared, paid, set aside or made to the holders of Preferred Shares thereof shall be equal to the dividend or distribution that such holders of Preferred Shares would have received pursuant to this Section (1) of Schedule A if such Preferred Share had been converted into Ordinary Shares immediately prior to the record date for such dividend or distribution, or if no such record date is established, the date such dividend or distribution is made, and if such share then participated in and the holder thereof received such dividend or distribution.

(b) Each holder of a Preferred Share shall be entitled to receive, on an annual basis, preferential, non-cumulative dividends for each Preferred Share (on an as-if-converted basis) held by such holder, payable in cash or assets when and as such cash or assets become legally available therefor on parity with each other, prior and in preference to, and satisfied before, any dividend on any other Shares; provided that such dividends shall be payable only when, as, and if declared by the Board. All accrued but unpaid dividends shall be paid when and as such cash or assets become legally available to the holders of Preferred Shares (on an as-if-converted basis) immediately prior to the closing of a Qualified IPO or a Deemed Liquidation Event.

SCHEDULE A-1

2. Liquidation Preference

(a) Liquidation Preferences. Upon any liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary, all assets and funds legally available for distributions to the Members of the Company shall be made in the following manner:

(i) Before any distribution or payment shall be made to the holders of any Ordinary Shares, the holders of any Series A+ Preferred Shares, the holders of any Series A Preferred Shares and the holders of any Series B Preferred Shares, each holder of Series C Preferred Shares then issued and outstanding shall be entitled to receive, on a pari-passu basis, an amount equal to the sum of one hundred and twenty percent (120%) of the applicable Series C Preferred Issue Price (as adjusted for any share splits, share dividends, combinations, recapitalizations and similar transactions) plus all dividends accrued and unpaid with respect thereto (as adjusted for any share splits, share dividends, combinations, recapitalizations and similar transactions) per Series C Preferred Share then held by such holder (hereinafter “Series C Preferred Shares Liquidation Amount”). If, upon any such liquidation, dissolution, winding up or a Deemed Liquidation Event of the Company, the assets of the Company available for distribution to its shareholders shall be insufficient to pay the holders of Series C Preferred Shares the full amount to which they shall be entitled under this Section 2(a)(i), the assets legally available for distribution shall be distributed among the holders of Series C Preferred Shares on a pro rata basis in proportion to the respective Series C Preferred Shares Liquidation Amount that each holder of Series C Preferred Shares is entitled hereunder.

(ii) After the holders of the Series C Preferred Shares receive in full the Series C Preferred Shares Liquidation Amount, and before any distribution or payment shall be made to the holders of any Ordinary Shares, the holders of any Series A+ Preferred Shares, the holders of any Series A Preferred Shares, each holder of Series B Preferred Shares then issued and outstanding shall be entitled to receive, on a pari-passu basis, an amount equal to the sum of one hundred and fifty percent (150%) of the applicable Series B Preferred Issue Price (as adjusted) plus all dividends accrued and unpaid with respect thereto (as adjusted) per Series B Preferred Share then held by such holder (hereinafter

SCHEDULE A-2

“Series B Preferred Shares Liquidation Amount”). If, upon any such liquidation, dissolution, winding up or a Deemed Liquidation Event of the Company, the assets of the Company available for distribution to its shareholders shall be insufficient to pay the holders of Series B Preferred Shares the full amount to which they shall be entitled under this Section 2(a)(ii), the assets legally available for distribution shall be distributed among the holders of Series B Preferred Shares on a pro rata basis in proportion to the respective Series B Preferred Shares Liquidation Amount that each holder of Series B Preferred Shares is entitled hereunder.

(iii) After the holders of the Series C Preferred Shares and Series B Preferred Shares receive in full the Series C Preferred Shares Liquidation Amount and the Series B Preferred Shares Liquidation Amount respectively, and before any distribution or payment shall be made to the holders of any Ordinary Shares, (x) each holder of the Series A Preferred Shares then issued and outstanding shall be entitled to receive, on a pari-passu basis, an amount equal to the sum of one hundred and fifty percent (150%) of the applicable Series A Preferred Issue Price (as adjusted) plus all dividends accrued and unpaid with respect thereto (as adjusted) per Series A Preferred Share then held by such holder (hereinafter “Series A Preferred Shares Liquidation Amount”), and (y) each holder of the Series A+ Preferred Shares then issued and outstanding shall be entitled to receive, on a pari-passu basis, an amount equal to the sum of one hundred and fifty percent (150%) of the applicable Series A+ Preferred Issue Price (as adjusted) plus all dividends accrued and unpaid with respect thereto (as adjusted) per Series A+ Preferred Share then held by such holder (hereinafter “Series A+ Preferred Shares Liquidation Amount”, together with Series A Preferred Shares Liquidation Amount, Series B Preferred Shares Liquidation Amount and Series C Preferred Shares Liquidation Amount, the “Preferred Shares Liquidation Amount”). If, upon any such liquidation, dissolution, winding up or a Deemed Liquidation Event of the Company, the assets of the Company available for distribution to its shareholders shall be insufficient to pay the holders of Series A Preferred Shares and the holders of Series A+ Preferred Shares the full amount to which they shall be entitled under this Section 2(a)(iii), the assets legally available for distribution shall be distributed among the holders of Series A Preferred Shares and the holders of Series A+ Preferred Shares on a pro rata basis in proportion to the respective Preferred Shares Liquidation Amount that each holder of Series A Preferred Shares and each holder of Series A+ Preferred Shares is entitled hereunder.

SCHEDULE A-3

(iv) After distribution or payment in full of Preferred Shares Liquidation Amount pursuant to Section 2(a)(i), Section 2(a)(ii) and Section 2(a)(iii) of Schedule A, the remaining assets of the Company available for distribution to shareholders shall be distributed ratably among the holders of issued and outstanding Ordinary Shares and holders of Preferred Shares on an as-converted basis.

(b) Liquidation on Sale or Merger. The following events shall be treated as a liquidation (each, a “Deemed Liquidation Event”) under this Section 2(b) of Schedule A unless waived by the (i) the Majority Preferred Shares Holders and (ii) the Majority Series C Preferred Share Holders:

(i) Trade Sale; or

(ii) Loss of Control.

and upon any such event, any proceeds arising from the Deemed Liquidation Event shall be distributed in accordance with the terms of paragraph (a) of this Section 2 of Schedule A.

(c) Amount Deemed Paid or Distributed. The amount deemed paid or distributed to the shareholders of the Company upon any such Deemed Liquidation Event shall be the cash or the value of the property, rights or securities paid or distributed to such holders by the Company or the acquiring Person. If the amount deemed paid or distributed under this Section 2(c) is made in property other than in cash, the value of such distribution shall be the fair market value of such property, determined in good faith by the Board (including the affirmative vote on one-half (1/2) of the Key Investors’ Directors). Any securities not subjected to investment letter or similar restrictions on free marketability shall be valued as follows:

(i) If traded on a securities exchange, the value shall be deemed to be the average of the security’s closing prices on such exchange over the thirty (30) day period ending one (1) day prior to the distribution;

SCHEDULE A-4

(ii) If traded over-the-counter, the value shall be deemed to be the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the distribution; and

(iii) If there is no active public market, the value shall be the fair market value thereof as determined in good faith by the Board (including the affirmative vote on one-half (1/2) of the Key Investors’ Directors).

The method of valuation of securities subject to investment letter or other restrictions on free marketability shall be adjusted to make an appropriate discount from the market value determined as above in clauses (i), (ii) or (iii) to reflect the fair market value thereof as determined in good faith by the Board (including the affirmative vote on one-half (1/2) of the Key Investors’ Directors), or by a liquidator if one is appointed.

The Majority Preferred Shares Holders shall have the right to challenge any determination by the Board of fair market value pursuant to this Section 2(c) of Schedule A, in which case the determination of fair market value shall be made by an independent appraiser selected jointly by the Board and the challenging parties, the cost of such appraisal to be borne equally by the Company and the challenging parties.

(d) Allocation of Escrow or Contingent Consideration. In the event of a Deemed Liquidation Event pursuant to Section 2(b), if any portion of the consideration payable to the shareholders of the Company is placed into escrow, the relevant acquisition agreement shall provide that (i) the portion of such consideration that is placed in escrow shall be allocated among the holders of shares of the Company pro rata based on the amount of such consideration payable to each shareholder (such that each shareholder has the same percentage of the total consideration payable to it placed into escrow), and (ii) the portion of such consideration that is not placed in escrow shall be allocated among the holders of shares of the Company in accordance with Section 2(a) as if the total consideration payable to the shareholders of the Company, without deduction for the escrowed amount, were being paid to the shareholders of the Company.

(e) Waiver of Liquidation Preference Rights. Notwithstanding the foregoing, in the event that the valuation of the Company at liquidation is higher than US$1,442,496,338, the holders of Preferred Shares shall have agreed to waive the liquidation preference

SCHEDULE A-5

rights provided in this Section 2, in which case, then all proceeds legally available for distribution to members of the Company under circumstances provided in this Section 2 shall be distributed ratably among the holders of Ordinary Shares and holders of the Preferred Shares on an as-converted basis.

3. Voting Rights

Subject to the provisions of the Memorandum and these Articles, at all general meetings of the Company: (i) the holder of each Ordinary Share issued and outstanding shall have one (1) vote in respect of each Ordinary Share held, and (ii) the holder of each Preferred Share shall be entitled to such number of votes as equals the whole number of Ordinary Shares into which such holder’s collective Preferred Shares (including such Preferred Shares assuming the full exercise of the purchase right pursuant to the GIC Warrant) are convertible immediately after the close of business on the record date of the determination of the Company’s shareholders entitled to vote or, if no such record date is established, at the date such vote is taken or any written consent of the Company’s shareholders is first solicited. Subject to provisions to the contrary elsewhere in the Memorandum and these Articles, or as required by the Statute, the holders of Preferred Shares shall vote together with the holders of Ordinary Shares, and not as a separate class or series (on an as converted and as-exercised basis), on all matters put before the shareholders.

4. Conversion Rights

The holders of the Preferred Shares shall have the following rights described below with respect to the conversion of the Preferred Shares into Ordinary Shares. Subject to the provisions of Section 4(b) of Schedule A, the number of Ordinary Shares to which a holder shall be entitled upon conversion of any Preferred Share shall be the quotient of the applicable Original Preferred Issue Price divided by the then-effective applicable Conversion Price. The “Conversion Price” shall initially equal the Original Preferred Issue Price, and shall be adjusted from time to time as provided below, being no less than par value. For the avoidance of doubt, the initial conversion ratio for Preferred Shares to Ordinary Shares shall be 1:1.

(a) Optional Conversion.

(i) Subject to and in compliance with the provisions of this Section 4(a) of Schedule A, and subject to compliance with the requirements of the Statute, any Preferred Share may, at the option of the holder thereof, be converted at

SCHEDULE A-6

any time after the date of issuance of such shares, without the payment of any additional consideration, into fully-paid and nonassessable Ordinary Shares based on the then-effective applicable Conversion Price.

(ii) The holder of any Preferred Shares who desires to convert such shares into Ordinary Shares shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Company or any transfer agent for the Preferred Shares, and shall give written notice to the Company at such office that such holder has elected to convert such shares. Such notice shall state the number of Preferred Shares being converted. Thereupon, the Company shall promptly issue and deliver to such holder at such office a certificate or certificates for the number of Ordinary Shares to which the holder is entitled and update its register of members accordingly. No fractional Ordinary Shares shall be issued upon conversion of the Preferred Shares, and the number of Ordinary Shares to be so issued to a holder of Preferred Shares upon the conversion of such Preferred Shares (after aggregating all fractional Ordinary Shares that would be issued to such holder) shall be rounded to the nearest whole share (with one-half being rounded upward). Such conversion shall be deemed to have been made at the close of business on the date of the register of members being updated and surrender of the certificates representing the Preferred Shares to be converted, the register of members of the Company shall be updated accordingly to reflect the same, and the person entitled to receive the Ordinary Shares issuable upon such conversion shall be treated for all purposes as the record holder of such Ordinary Shares on such date.

(b) Automatic Conversion.

(i) Without any action being required by the holder of such share and whether or not the certificates representing such share are surrendered to the Company or its transfer agent and without the payment of any additional consideration, the Preferred Shares shall automatically be converted into fully-paid and non assessable Ordinary Shares upon the closing of a Qualified IPO.

(ii) The Company shall not be obligated to issue certificates for any Ordinary Shares issuable upon the automatic conversion of any Preferred Shares unless the certificate or certificates evidencing such Preferred Shares is either delivered as provided below to the Company or any transfer agent for the

SCHEDULE A-7

Preferred Shares, or the holder notifies the Company or its transfer agent that such certificate has been lost, stolen or destroyed and executes an agreement satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with such certificate. The Company shall, as soon as practicable after receipt of certificates for Preferred Shares, or satisfactory agreement for indemnification in the case of a lost certificate, promptly issue and deliver at its office to the holder thereof a certificate or certificates for the number of Ordinary Shares to which the holder is entitled and update its register of members accordingly. No fractional Ordinary Shares shall be issued upon conversion of the Preferred Shares, and the number of Ordinary Shares to be so issued to a holder of converting Preferred Shares (after aggregating all fractional Ordinary Shares that would be issued to such holder) shall be rounded to the nearest whole share (with one-half being rounded upward). Any person entitled to receive Ordinary Shares issuable upon the automatic conversion of the Preferred Shares shall be treated for all purposes as the record holder of such Ordinary Shares on the date of such conversion or pursuant to the register of members of the Company being updated.

(c) Mechanics of Conversion. The conversion hereunder of any Preferred Share (the “Conversion Share”) shall be effected in the following manner:

(i) The Company shall redeem the Conversion Share for aggregate consideration (the “Redemption Amount”) equal to (a) the aggregate par value of any capital shares of the Company to be issued upon such conversion and (b) the aggregate value, as determined by the Board, of any other assets which are to be distributed upon such conversion.

(ii) Concurrent with the redemption of the Conversion Share, the Company shall apply the Redemption Amount for the benefit of the holder of the Conversion Share to pay for any capital shares of the Company issuable, and any other assets distributable, to such holder in connection with such conversion and update its register of members accordingly.

(iii) Upon application of the Redemption Amount, the Company shall issue to the holder of the Conversion Share all capital shares issuable, and distribute to such holder all other assets distributable, upon such conversion.

SCHEDULE A-8

(d) Adjustments to Conversion Price.

(i) Adjustment for Share Splits and Combinations. If the Company shall at any time, or from time to time, effect a subdivision of the issued and outstanding Ordinary Shares, the applicable Conversion Price in effect immediately prior to such subdivision shall be proportionately decreased. Conversely, if the Company shall at any time, or from time to time, combine the issued and outstanding Ordinary Shares into a smaller number of shares, the applicable Conversion Price in effect immediately prior to the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective.

(ii) Adjustment for Ordinary Share Dividends and Distributions. If the Company makes (or fixes a record date for the determination of holders of Ordinary Shares entitled to receive) a dividend or other distribution to the holders of Ordinary Shares payable in Additional Ordinary Shares, the applicable Conversion Price then in effect shall be decreased as of the time of such issuance (or in the event such record date is fixed, as of the close of business on such record date) by multiplying such Conversion Price then in effect by a fraction (i) the numerator of which is the total number of Ordinary Shares issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (ii) the denominator of which is the total number of Ordinary Shares issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of Ordinary Shares issuable in payment of such dividend or distribution.

(iii) Adjustments for Other Dividends. If the Company at any time, or from time to time, makes (or fixes a record date for the determination of holders of Ordinary Shares entitled to receive) a dividend or other distribution payable in securities of the Company other than Ordinary Shares or Ordinary Share Equivalents, then, and in each such event, provision shall be made so that, upon conversion of any Preferred Share thereafter, the holder thereof shall receive, in addition to the number of Ordinary Shares issuable thereon, the amount of securities of the Company which the holder of such share would have received had the Preferred Shares been converted into Ordinary Shares immediately prior to such event, all subject to further adjustment as provided herein.

SCHEDULE A-9

(iv) Reorganizations, Mergers, Consolidations, Reclassifications, Exchanges, Substitutions. If at any time, or from time to time, any capital reorganization or reclassification of the Ordinary Shares (other than as a result of a share dividend, subdivision, split or combination otherwise treated above) occurs or the Company is consolidated, merged or amalgamated with or into another Person (other than a consolidation, merger or amalgamation treated as a Deemed Liquidation Event), then in any such event, provision shall be made so that, upon conversion of any Preferred Share thereafter, the holder thereof shall receive the kind and amount of shares and other securities and property which the holder of such share would have received had the Preferred Shares been converted into Ordinary Shares on the date of such event, all subject to further adjustment as provided herein, or with respect to such other securities or property, in accordance with any terms applicable thereto.

(v) Sale of Shares below the Conversion Price.

(A) Special Definition. For purpose of this f this Section 4 of Schedule A, the following definitions shall apply:

(i) “Options” mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Ordinary Shares or Convertible Securities.

(ii) “Convertible Securities” shall mean any indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Ordinary Shares.

(b)    Waiver of Adjustment. No adjustment in the applicable Conversion Price shall be made as the result of the issuance or deemed issuance of Additional Equity Securities if the Company receives written notice from the holders of the Majority Series A Preferred Shares Holders, the Majority Series A+ Preferred Shares Holders, the Majority Series B Preferred Shares Holders or the Majority Series C Preferred Shares Holders agreeing that no such adjustment shall be

SCHEDULE A-10

made with respect to such series or class of Preferred Shares as the result of the issuance or deemed issuance of such Additional Equity Securities.

(c)    Deemed Issuance of New Securities. In the event the Company at any time or from time to time after the Original Series C Issue Date shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any series or class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of Ordinary Shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number for anti-dilution adjustments) 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 or the exercise of such Options, shall be deemed to be Additional Equity Securities issued as of the time of such issue 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 Equity Securities are deemed to be issued:

(i)    no further adjustment in the applicable Conversion Price shall be made upon the subsequent issue of Convertible Securities or Ordinary Shares upon the exercise of such Options or conversion or exchange of such Convertible Securities or upon the subsequent issue of Options for Convertible Securities or Ordinary Shares;

(ii)    if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any change in the consideration payable to the Company, or change in the number of Ordinary Shares issuable, upon the exercise, conversion or exchange thereof, the then effective applicable Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any

SCHEDULE A-11

such change becoming effective, be recomputed to reflect such change insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

(iii)    no readjustment pursuant to the above clause (ii) shall have the effect of increasing the then effective applicable Conversion Price to an amount which exceeds the Conversion Price that would have been in effect had no adjustments in relation to the issuance of such Options or Convertible Securities as referenced in the above clause (ii) been made;

(iv)    upon the expiration of any such Options or any rights of conversion or exchange under such Convertible Securities that have not been exercised, the then effective applicable Conversion Price computed upon the original issue 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:

(x)    in the case of Convertible Securities or Options for Ordinary Shares, the only Additional Equity Securities issued were the 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 issue of such exercised Options plus the consideration actually received by the Company upon such exercise or for the issue of all such Convertible Securities that were actually converted or exchanged, plus the additional consideration, if any, actually received by the Company upon such conversion or exchange, and

(y)    in the case of Options for Convertible Securities, only the Convertible Securities, if any,

SCHEDULE A-12

actually issued upon the exercise thereof were issued at the time of issue of such Options, and the consideration received by the Company for the Additional Equity Securities deemed to have been then issued was the consideration actually received by the Company for the issue of such exercised Options, plus the consideration deemed to have been received by the Company upon the issue of the Convertible Securities with respect to which such Options were actually exercised; and

(v)    if such record date shall have been fixed and such Options or Convertible Securities are not issued on the date fixed therefor, the adjustment previously made in the applicable Conversion Price which became effective on such record date shall be canceled as of the close of business on such record date, and thereafter the applicable Conversion Price shall be adjusted pursuant to this Section 4(d)(v) of Schedule A as of the actual date of their issuance.

(A) Adjustment of Conversion Price Upon Issuance of Additional Equity Securities.

In the event the Company shall at any time or from time to time after the Original Series C Issue Date issue Additional Equity Securities, for a minimum consideration allowed by applicable laws or for a consideration per share less than the applicable Conversion Price of any series of Preferred Shares then in effect immediately prior to such issue (the “Dilutive Issue Price”), then, the applicable Conversion Price of the affected series of Preferred Shares shall be reduced, concurrently with such issue to the Dilutive Issue Price (calculated to the nearest cent). Notwithstanding the foregoing, the Conversion Price of the Preferred Shares shall not be reduced at such time if the amount of such reduction would be less than US$0.01, but any such amount shall be carried forward, and a reduction will be made with respect to such amount at the time of, and together with, any subsequent reduction which, together with such amount and any other amounts so carried forward, equal US$0.01 or more in the aggregate.

SCHEDULE A-13

(B) Determination of Consideration. For the purpose of making any adjustment to any applicable Conversion Price or the number of Ordinary Shares issuable upon conversion of the Preferred Shares, as provided above:

(1) To the extent it consists of cash, the consideration received by the Company for any issue or sale of securities shall be computed at the net amount of cash received by the Company after deduction of any underwriting or similar commissions, compensations, discounts or concessions paid or allowed by the Company in connection with such issue or sale;

(2) To the extent it consists of property other than cash, consideration other than cash received by the Company for any issue or sale of securities shall be computed at the fair market value thereof (as determined in good faith by a majority of the Board (including the affirmative vote on one-half (1/2) of the Key Investors’ Directors), as of the date of the adoption of the resolution specifically authorizing such issue or sale, irrespective of any accounting treatment of such property; and

(3) If Additional Ordinary Shares or Ordinary Share Equivalents exercisable, convertible or exchangeable for Additional Ordinary Shares are issued or sold together with other stock or securities or other assets of the Company for consideration which covers both, the consideration received for the Additional Ordinary Shares or such Ordinary Share Equivalents shall be computed as that portion of the consideration received (as determined in good faith by a majority of the Board (including the affirmative vote on one-half (1/2) of the Key Investors’ Directors) to be allocable to such Additional Ordinary Shares or Ordinary Share Equivalents.

SCHEDULE A-14

(C) No Exercise. If all of the rights to exercise, convert or exchange any Ordinary Share Equivalents shall expire without any of such rights having been exercised, the applicable Conversion Price as adjusted upon the issuance of such Ordinary Share Equivalents shall be readjusted to the applicable Conversion Price which would have been in effect had such adjustment not been made.

(vi) Other Dilutive Events. In case any event shall occur as to which the other provisions of this Section 4 of Schedule A are not strictly applicable, but the failure to make any adjustment to any Conversion Price would not fairly protect the conversion rights of the applicable series of 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 Section 4 of Schedule A necessary to preserve the conversion rights of such series of Preferred Shares. (vii) Certificate of Adjustment. In the case of any adjustment or readjustment of a Conversion Price, the Company, at its sole expense, shall compute such adjustment or readjustment in accordance with the provisions hereof and prepare a certificate showing such adjustment or readjustment, and shall mail such certificate, by first class mail, postage prepaid, to each registered holder of such series of Preferred Shares at such holder’s address as shown in the Company’s books. The certificate shall set forth such adjustment or readjustment, showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (i) the consideration received or deemed to be received by the Company for any Additional Ordinary Shares issued or sold or deemed to have been issued or sold, (ii) the number of Additional Ordinary Shares issued or sold or deemed to be issued or sold, (iii) the applicable Conversion Price in effect before and after such adjustment or readjustment, and (iv) the number of Ordinary Shares and the type and amount, if any, of other property which would be received upon conversion of such series of Preferred Shares after such adjustment or readjustment.

(viii) Notice of Record Date. In the event the Company shall propose to take any action of the type or types requiring an adjustment to a Conversion Price or the number or character of the Preferred Shares as set forth herein, the

SCHEDULE A-15

Company shall give notice to the holders of such series of Preferred Shares, which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the Conversion Price and the number, kind or class of shares or other securities or property which shall be deliverable upon the occurrence of such action or deliverable upon the conversion of Preferred Shares. In the case of any action which would require the fixing of a record date, such notice shall be given at least twenty (20) days prior to the date so fixed, and in the case of all other actions, such notice shall be given at least thirty (30) days prior to the taking of such proposed action.

(ix) Reservation of Shares Issuable Upon Conversion. The Company shall at all times reserve and keep available out of its authorized but unissued Ordinary Shares, solely for the purpose of effecting the conversion of the Preferred Shares, such number of its Ordinary Shares as shall from time to time be sufficient to effect the conversion of all issued and outstanding Preferred Shares. If at any time the number of authorized but unissued Ordinary Shares shall not be sufficient to effect the conversion of all then issued and outstanding Preferred Shares, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued Ordinary Shares to such number of shares as shall be sufficient for such purpose.

(x) Notices. Any notice required or permitted pursuant to this Section 4 of Schedule A shall be given in writing and shall be given either personally or by sending it by next-day or second-day courier service, fax, electronic mail or similar means to each holder of record at the address of such holder appearing on the books of the Company. Where a notice is sent by next-day or second-day courier service, service of the notice shall be deemed to be effected by properly addressing, pre-paying and sending by next-day or second-day service through an internationally-recognized courier a letter containing the notice, with a confirmation of delivery, and to have been effected at the expiration of two (2) days after the letter containing the same is sent as aforesaid. Where a notice is sent by fax or electronic mail, service of the notice

SCHEDULE A-16

shall be deemed to be effected by properly addressing, and sending such notice through a transmitting organization, with a written confirmation of delivery, and to have been effected on the day the same is sent as aforesaid.

(xi) Payment of Taxes. The Company will pay all taxes (other than taxes based upon income) and other governmental charges that may be imposed with respect to the issue or allotment of Ordinary Shares upon conversion of Preferred Shares, excluding any tax or other charge imposed in connection with any transfer involved in the issue and allotment of Ordinary Shares in a name other than that in which the Preferred Shares so converted were registered.

(xii) No Impairment. The Company will not, by amendment of these Articles or through any reorganization, recapitalization, transfer of assets, consolidation, merger, amalgamation, scheme of arrangement, dissolution, issue 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 this Section 4 of Schedule A and in the taking of all such action as may be necessary or appropriate to protect the conversion rights of the holders of Preferred Shares against impairment.

(b) Insufficient Funds. If the Company’s assets or funds which are legally available on the date that any redemption payment under this Section 5 of Schedule A is due are insufficient to pay in full all redemption payments to be paid at the Redemption Closing, or if the Company is otherwise prohibited by applicable law from making such redemption, those assets or funds which are legally available shall be used in the following manner: (1) first, prior and in preference to all of the Series A Preferred Shares, the Series A+ Preferred Shares and the Series B Preferred Shares, all of Series C Preferred Shares required to be redeemed shall be redeemed, on a pari-passu basis, ratably in proportion to the Series C Redemption Price that each holder of Series C Preferred Shares is entitled hereunder; and if not all of the Series C Preferred Shares required to be redeemed are able to be redeemed, then the Series C Preferred Shares to be redeemed shall be allocated ratably to the holders of the Series C Preferred Shares in proportion to the Series C Redemption Price that each holder of the Series C Preferred Shares is entitled hereunder, and then the redemption amount with respect to the remaining Series C Preferred Shares to be redeemed shall be paid as soon as the Company has legally available funds to do so but in any event within one year to such holder of Series C Preferred Shares bearing 12% annual compounded interest; (2)

SCHEDULE A-21

second, after full payment of the Series C Redemption Price of the Series C Preferred Shares to be redeemed, all of Series B Preferred Shares required to be redeemed shall be redeemed, on a pari-passu basis, ratably in proportion to the Series B Redemption Price that each holder of Series B Preferred Shares is entitled hereunder; and if not all of the Series B Preferred Shares required to be redeemed are able to be redeemed, then the Series B Preferred Shares to be redeemed shall be allocated ratably to the holders of the Series B Preferred Shares in proportion to the Series B Redemption Price that each holder of the Series B Preferred Shares is entitled hereunder, and then the redemption amount with respect to the remaining Series B Preferred Shares to be redeemed shall be paid within one year to such holder of Series B Preferred Shares bearing 12% annual simple interest; and (3) third, after full payment of the Series C Redemption Price of the Series C Preferred Shares to be redeemed and the Series B Redemption Price of the Series B Preferred Shares to be redeemed, all of the Series A Preferred Shares and the Series A+ Preferred Shares required to be redeemed shall be redeemed, on a pari-passu basis, ratably in proportion to the respective Redemption Price that each holder of the Series A Preferred Shares and each holder of the Series A+ Preferred Shares is entitled hereunder; and if not all of the Series A Preferred Shares and the Series A+ Preferred Shares required to be redeemed are able to be redeemed, then the Series A Preferred Shares and the Series A+ Preferred Shares to be redeemed shall be allocated ratably to the holders of the Series A Preferred Shares and the holders of the Series A+ Preferred Shares in proportion to the Redemption Price that each holder of the Series A Preferred Shares and each holder of the Series A+ Preferred Shares is entitled hereunder, and then the redemption amount with respect to the remaining Series A Preferred Shares and the Series A+ Preferred Shares to be redeemed shall be paid within one year to such holder of the Series A Preferred Shares and such holder of the Series A+ Preferred Shares bearing 12% annual simple interest. Thereafter, all assets or funds of the Company that become legally available for the redemption of shares shall immediately be used to pay the redemption payments which the Company did not pay on the date that such redemption payments were due. Without limiting any rights of the holders of Preferred Shares which are set forth in these Articles, or are otherwise available under law, the balance of any shares subject to redemption hereunder with respect to which the Company has become obligated to pay the redemption payment but which it has not paid in full shall continue to have all the powers, designations, preferences and relative participating, optional, and other special rights (including, without limitation, rights to accrue dividends) which such shares had prior to such date, until the redemption payments has been paid in full with respect to such shares.

Once the Company has received a Redemption Notice, it shall not, and shall not permit any Subsidiary to, take any action which could have the effect of delaying, undermining or restricting the redemption, and the Company shall in good faith use all reasonable efforts as expeditiously as possible to increase the amount of legally available redemption funds including, to the extent permitted by law, procuring that any and all profits of each Subsidiary of the Company for the time being available for distribution shall be paid to it by way of dividend if and to the extent that, but for such dividend upstream, the Company would not itself otherwise have sufficient profits available for distribution to make any redemption of applicable Preferred Shares required to be made pursuant to this Section 5 of Schedule A, and until the date on which each applicable Preferred Share required to be deemed is redeemed, the Company shall not declare or pay any dividend nor otherwise make any distribution of or otherwise decrease its profits available for distribution without the prior written consent of all Preferred Shareholders who have delivered a Redemption Notice and have not been fully paid the applicable Redemption Price.

(d) Other Limited Redemption. If the Company is otherwise prohibited by applicable law from redeeming all applicable Preferred Shares to be redeemed at the Redemption Closing, those assets or funds which are legally available shall be used to the extent permitted by applicable Law to pay all redemption payments due on such date ratably in proportion to the full amounts to which the holders to which such redemption payments are due would otherwise be respectively entitled thereon. Thereafter, all assets or funds of the Company that become legally available for the redemption of shares shall immediately be used to pay the redemption payment which the Company did not pay on the date that such redemption payments were due.

(e) Un-redeemed Shares. Without limiting any rights of the holders of Preferred Shares which are set forth in these Articles, or are otherwise available under law, the balance of any shares subject to redemption hereunder with respect to which the Company has become obligated to pay the redemption payment but which it has not paid in full shall continue to have all the rights (including its voting rights), powers, designations, preferences and relative participating, optional, and other special rights (including, without limitation, rights to accrue dividends) which such shares had prior to such date, until the redemption payment has been paid in full with respect to such shares.
