2.2

Rights of First Refusal.

(a)

Transfer Notice.

Prior to the closing of a Qualified IPO, if a Restricted Shareholder proposes to transfer the Equity Securities he or it directly or indirectly holds in the Company to one or more third parties pursuant to an understanding with such third parties (a “Transfer”, and such holder a “Transferor”), then the Transferor shall, subject to the applicable statutory provisions and the Memorandum and Articles, give the Company written notice of the Transferor’s intention to make the Transfer (the “Transfer Notice”), which shall include (i) a description of the Equity Securities to be transferred (the “Offered Shares”), (ii) subject to any applicable non-disclosure agreement with such third party, the identity of the prospective transferee and (iii) the consideration and the material terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Transferor has received a firm offer from the prospective transferee and in good faith believes a binding agreement for the Transfer is obtainable on the terms set forth in the Transfer Notice.

(b)

Company’s Option.

(i) The Company shall have an option for a period of fifteen (15) days following the receipt of the Transfer Notice to elect to purchase all of the Offered Shares (not in part) at the same price and subject to the same material terms and conditions as described in the Transfer Notice, subject further to complying with all the applicable statutory provisions (including, without limitation, the Companies Law of the Cayman Islands) and the Memorandum and Articles.

(ii) The Company may exercise such purchase option and, thereby, purchase all of the Offered Shares, by notifying the Transferor in writing, before expiration of the fifteen (15) day period, that it wishes to purchase all of the Offered Shares.

(iii) If the Company gives the Transferor notice that it desires to purchase Offered Shares, then payment for the Offered Shares to be purchased shall be by check or wire transfer in immediately available funds of the appropriate currency, against delivery of such Offered Shares to be purchased at a place agreed by the Transferor and the Company and at the time of the scheduled closing therefor, which shall be no later than forty-five (45) days after the Company’s receipt of the Transfer Notice, unless such notice contemplated a later closing with the prospective third party transferee or unless the value of the purchase price has not yet been established pursuant to Section 2.2(d) or if later, the day on which all the mandatory statutory procedures shall have been completed.

(iv) Regardless of any other provision of this Agreement, if the Company declines in writing, or fails to exercise its purchase option pursuant to this Section 2.2 with respect to all (and not less than all) Offered Shares, then the Transferor shall be under no obligation to transfer the Offered Shares to the Company pursuant to this Section 2.2 and shall then be required to provide a Transfer Notice regarding the Offered Shares to the Holders (the “Holder Transfer Notice”) pursuant to Section 2.2(c).

(v) The Transferor shall have the right to terminate or withdraw any Transfer Notice and any intent to transfer Offered Shares at any time, whether or not the Company has elected to purchase under this Section 2.2 any Offered Shares offered thereby.

(c)

Holders’ Option.

(i) If the Company at any time elects not to purchase all of the Offered Shares pursuant to its right of first refusal in Section 2.2(b) hereof, then each Holder shall have an option for a period of fifteen (15) days following such Holder’s receipt of the Holder Transfer Notice to elect to purchase its respective pro rata share of the Offered Shares at the same price and subject to the same material terms and conditions as described in the Holder Transfer Notice.

(ii) Each such Holder may exercise such purchase option and, thereby, purchase all or any portion of its pro rata share (with any re-allotment as provided below) of the Offered Shares, by notifying the Transferor and the Company in writing, before expiration of the fifteen (15) day period as to the number of such shares that it wishes to purchase (including any re-allotment).

(iii) Each such Holder’s pro rata share of the Offered Shares shall be a fraction, the numerator of which shall be the number of Equity Securities (assuming the exercise, conversion and exchange of any Ordinary Share Equivalents) owned by such Holder on the date of the Holder Transfer Notice and the denominator of which shall be the total number of Equity Securities (assuming the exercise, conversion and exchange of any Ordinary Share Equivalents) held by all Holders on such date, multiplied by the Offered Shares.

(iv) If any Holder fails to exercise such purchase option pursuant to this Section 2.2, the Transferor shall give notice of such failure (the “Re-allotment Notice”) to each other Holder that elected to purchase its entire pro rata share of the Offered Shares (the “Purchasing Holders”). Such Re-allotment Notice may be made by telephone if confirmed in writing within two (2) days. The Purchasing Holders shall have a right of re-allotment such that they shall have ten (10) days from the date such Re-allotment Notice was given to elect to increase the number of Offered Shares they agreed to purchase under Section 2.2(c)(iii) to include their respective pro rata share of the Offered Shares contained in any Re-allotment Notice.

(v) Subject to applicable securities Laws, the Holder shall be entitled to apportion Offered Shares to be purchased among its partners and Affiliates upon written notice to the Company and the Transferor.

(vi) If a Holder gives the Transferor notice that it desires to purchase Offered Shares, then payment for the Offered Shares to be purchased shall be by check or wire transfer in immediately available funds of the appropriate currency, against delivery of such Offered Shares

to be purchased at a place agreed by the Transferor and all the participating Holders and at the time of the scheduled closing therefor, which shall be no later than forty-five (45) days after the Holder’s receipt of the Holder Transfer Notice, unless such notice contemplated a later closing with the prospective third party transferee or unless the value of the purchase price has not yet been established pursuant to Section 2.2(d).

(vii) Regardless of any other provision of this Agreement, if the Holders decline in writing, or fail to exercise their purchase option pursuant to this Section 2.2(c) with respect to all (and not less than all) Offered Shares, the Transferor shall be under no obligation to transfer the Offered Shares to the Holders or the Company pursuant to this Section 2.2 and instead shall be free to sell such Offered Shares pursuant to the Holder Transfer Notice, subject to Sections 2.3 and 2.4 hereunder.

(viii) The Transferor shall have the right to terminate or withdraw any Holder Transfer Notice and any intent to transfer Offered Shares at any time, whether or not any Holder has elected to purchase under this Section 2.2(c) any Offered Shares offered thereby.

(ix) If the Company or any Holder exercises its right of first refusal to purchase the Offered Shares, then, upon the date of the completion of the relevant share transfers, the Transferor will have no further rights as a holder of such Offered Shares except the right to receive payment for such Offered Shares from the Company or such Holder in accordance with the terms of this Agreement, and the Transferor will forthwith cause all certificate(s) evidencing such Offered Shares to be surrendered to the Company for cancellation or transfer to such Holder.

(x) In the event that the Company or Holders have not elected to purchase all of the Offered Shares, then the sale of the remaining Offered Shares will become subject to the co-sale right of the Holders as set forth in Section 2.3 below.

(d)

Valuation of Property.

(i) Should the purchase price specified in the Transfer Notice or Holder Transfer Notice be payable in property other than cash or evidences of indebtedness, the Holders or the Company, as the case may be, shall have the right to pay the purchase price in the form of cash equal in amount to the fair market value of such property.

(ii) If the Transferor, on the one hand, and the Holders or the Company, as the case may be, on the other hand, cannot agree on such cash value within seven (7) days after the Holders’ receipt of the Holder Transfer Notice or the Company’s receipt of the Transfer Notice, the valuation shall be made by an appraiser of internationally recognized standing jointly selected by the Transferor and the Holders or the Company, as the case may be, or, if they cannot agree on an appraiser within ten (10) days after the Holders’ receipt of the Holder Transfer Notice or the Company’s receipt of the Transfer Notice, each shall select an appraiser of internationally recognized standing and the two appraisers shall designate a third appraiser of internationally recognized standing, whose appraisal shall be determinative of such value.

(iii) The cost of such appraisal shall be shared equally by the Transferor and the Holders or the Company, as the case may be, with the half of the cost borne by the Holders to be

borne pro rata by each Holder based on the number of shares such Holder has elected to purchase pursuant to Section 2.2(c).

(iv) If the value of the purchase price offered by the prospective transferee is not determined within the time limit specified in Section 2.2(b)(iii) or Section 2.2(c)(vi) above, the closing of the Holders’ or the Company’s purchase shall be held on or prior to the fifth business day after such valuation shall have been made pursuant to this Section 2.2(d).

2.3

Right of Co-Sale.

(a) To the extent the applicable Holders do not exercise their respective right of first refusal as to all of the Offered Shares pursuant to Section 2.2(c), each Holder that did not exercise its right of first refusal as to any of the Offered Shares pursuant to Section 2.2(c) shall have the right to participate in such sale of Equity Securities on the same terms and conditions as specified in the Transfer Notice by notifying the Transferor in writing within fifteen (15) days after receipt of the Holder Transfer Notice referred to in Section 2.2(b) (each such Holder, a “Selling Holder”).¹

(i) Such Selling Holder’s notice to the Transferor shall indicate the number of Equity Securities the Selling Holder wishes to sell under its right to participate.

(ii) To the extent one or more of the Holders exercises such right of participation in accordance with the terms and conditions set forth below, the number of Equity Securities that the Transferor may sell in the Transfer shall be correspondingly reduced.

(b) Each Selling Holder may elect to sell such number of Equity Securities that in the aggregate equals the total number of Offered Shares being transferred following the exercise or expiration of all rights of first refusal pursuant to Sections 2.2(b) and 2.2(c) hereof on a pro rata basis. Each Selling Holder may elect to sell such number of Equity Securities that equals the product of (i) the aggregate number of the Offered Shares being transferred following the exercise or expiration of all rights of first refusal pursuant to Sections 2.2(b) and 2.2(c) hereof multiplied by (ii) a fraction, the numerator of which is the number of Ordinary Shares (on an as-if-converted basis which includes the number of Ordinary Shares that would be issuable upon the exercise, conversion or exchange of Ordinary Share Equivalents) owned by the Selling Holder on the date of the Transfer Notice and the denominator of which is the total number of Ordinary Shares (on an as-if-converted basis which includes the number of Ordinary Shares that would be issuable upon the exercise, conversion or exchange of Ordinary Share Equivalents) owned by all Selling Holders on the date of the Transfer Notice.

(c) If any Selling Holder fails to exercise such co-sale option pursuant to this Section 2.3, the Transferor shall give notice of such failure (the “Co-Sale Re-allotment Notice”) to each other Selling Holders that elected to sell its entire pro rata share of the Offered Shares (the “Co-Sale Selling Holders”). Such Co-Sale Re-allotment Notice may be made by telephone if confirmed in writing within two (2) days. The Co-Sale Selling Holders shall have a right of re-allotment such that they shall have ten (10) days from the date such Co-Sale Re-allotment


¹		Note to Han Kun: Please see definition of “Holder Transfer Notice”. Given this definition, no changes required to the 15 day period concept because the ROFR and Tag time periods are consistent.

Notice was given to elect to increase the number of Equity Securities they agreed to sell under Section 2.3(b) to include their respective pro rata share of the Equity Securities to be sold contained in any Co-Sale Re-allotment Notice.

(d) Each Selling Holder shall effect its participation in the sale by promptly delivering to the Transferor for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent the type and number of Equity Securities which such Selling Holder elects to sell; provided, however that if the prospective third-party purchaser objects to the delivery of any Ordinary Share Equivalents in lieu of Ordinary Shares, such Selling Holder shall only deliver Ordinary Shares (and therefore shall convert any such Ordinary Share Equivalents into Ordinary Shares) and certificates corresponding to such Ordinary Shares. The Company agrees to make any such conversion concurrent with the actual transfer of such shares to the purchaser and contingent on such transfer.

(e) The share certificate or certificates that a Selling Holder delivers to the Transferor pursuant to Section 2.3(d) shall be transferred to the prospective purchaser in consummation of the sale of the Equity Securities pursuant to the terms and conditions specified in the Transfer Notice, and the Transferor shall concurrently therewith remit to such Selling Holder that portion of the sale proceeds to which such Selling Holder is entitled by reason of its participation in such sale.

(f) To the extent that any prospective purchaser prohibits the participation of a Selling Holder exercising its co-sale rights hereunder in a proposed Transfer or otherwise refuses to purchase shares or other securities from a Selling Holder exercising its co-sale rights hereunder, the Transferor shall not sell to such prospective purchaser any Equity Securities unless and until, simultaneously with such sale, the Transferor shall purchase from such Selling Holder such shares or other securities that such Selling Holder would otherwise be entitled to sell to the prospective purchaser pursuant to its co-sale rights for the same consideration and on the same terms and conditions as the proposed transfer described in the Transfer Notice.

2.4

Non-Exercise of Rights.

(a) Subject to any other applicable restrictions on the sale of such shares, to the extent that the Holders have not exercised their rights to purchase the Offered Shares within the time periods specified in Sections 2.2(b) and 2.2(c) and the Holders have not exercised their rights to participate in the sale of the Offered Shares within the time periods specified in Section 2.3, the Transferor shall have a period of sixty (60) days from the expiration of such rights in which to sell the Offered Shares, as the case may be, to the third-party transferee identified in the Transfer Notice upon terms and conditions (including the purchase price) no more favorable to the purchaser than those specified in the Transfer Notice.

(b) In the event the Transferor does not consummate the sale or disposition of the Offered Shares within one hundred and twenty (120) days from the expiration of such rights, the Holders’ first refusal rights and co-sale rights shall continue to be applicable to any subsequent disposition of the Offered Shares by the Transferor until such rights lapse in accordance with the terms of this Agreement.

(c) The exercise or non-exercise of the rights of the Holders under this Section 2 to purchase Equity Securities from a Transferor or participate in the sale of Equity Securities by a Transferor shall not adversely affect their rights to make subsequent purchases from the Transferor of Equity Securities or subsequently participate in sales of Equity Securities by the Transferor hereunder.

(c) Notwithstanding any provision to the contrary contained herein, any Transfer of Equity Securities pursuant to the Option Agreements (as defined in that certain Share Exchange Agreement entered into by the Company and certain parties on January 15, 2010, the “Share Exchange Agreement”) shall not be subject to the transfer restrictions hereunder.

2.6

Change in Control. The Parties agree that, for purposes of the transfer restrictions in this Agreement and in certain other Transaction Documents (as defined in the Share Exchange Agreement), a transaction or series of transactions that result in a change in Control of a Shareholder shall be deemed to constitute a Transfer of such Restricted Shareholders’ Equity Securities.
