At the effective time of the Merger, the outstanding Ordinary Shares and ADSs will cease to be outstanding and will be cancelled, and each Ordinary Share (excluding the Rollover Shares (as defined below), Ordinary Shares or ADSs held in the Issuer’s treasury or held by the Parent or by any of their respective subsidiaries, and any Ordinary Shares or ADSs held by a shareholder of the Issuer who is entitled to and properly exercises appraisal rights under the applicable law of the Cayman Islands) will be converted into the right to receive cash consideration, without interest, equal to $0.81667 per Ordinary Share (or $4.90 per ADS). Shareholders of the Issuer who exercise their appraisal rights will have their Ordinary Shares cancelled in exchange for the right to receive the payment of fair value in accordance with the Companies Law of the Cayman Islands.

The financing for the Merger and other transactions contemplated by the Merger Agreement will be obtained pursuant to the Contribution Agreement and the Debt Commitment Letter (each as described below).

The Merger Agreement contains customary representations, warranties and covenants for a transaction of this type. The Merger Agreement also contains customary covenants, including covenants providing for each of the parties (i) to use reasonable best efforts to cause the transactions to be consummated and (ii) to call and hold an extraordinary shareholders’ meeting of the Issuer for purposes of voting and approving the Merger Agreement and recommend adoption of the Merger Agreement, subject to applicable fiduciary duties. The Merger Agreement also requires the Issuer to conduct its operations in all material respects according to the ordinary course of business consistent with past practice during the period between the execution of the Merger Agreement and the closing of the Merger. The Issuer is subject to customary “no-shop” restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide information to and engage in discussions with third parties regarding alternative acquisition proposals, subject to certain exceptions in certain circumstances prior to the approval of the Merger Agreement by the shareholders of the Issuer.

The consummation of the Merger is subject to the satisfaction or waiver of a number of conditions set forth in the Merger Agreement, including the approval of the

SCHEDULE 13D

Page 14 of 19

Merger Agreement by holders of Ordinary Shares representing two-thirds or more of the Ordinary Shares present and voting at an extraordinary shareholders’ meeting of the Issuer convened for purposes of voting on and approving the Merger Agreement. The Merger Agreement may be terminated by the Issuer or Parent under certain circumstances.

If the transactions contemplated by the Merger Agreement are consummated, the Issuer will become a privately-held company, and its ADSs would be deregistered under the Exchange Act and would be delisted from the NASDAQ Global Market.

Upon consummation of the Merger, the directors of Merger Sub at the effective time of the Merger and the officers of the Issuer at the effective time of the Merger will in each case be the directors and officers of the surviving corporation, unless otherwise determined by Parent prior to the effective time, until their respective successors are duly elected and qualified or their death, resignation or removal in accordance with the memorandum and articles of association of the Issuer (as the surviving company).

Contribution Agreement

In connection with the transactions contemplated by the Merger Agreement, on June 8, 2015, the Rollover Shareholders and Parent entered into an equity contribution and voting agreement (the “Contribution Agreement”), pursuant to which, at the closing of the Merger, the Ordinary Shares (including the Ordinary Shares represented by ADSs) owned by the Rollover Shareholders as set forth in the Contribution Agreement (the “Rollover Shares”) will be cancelled pursuant to the Merger Agreement. Immediately prior to the closing of the Merger, each Rollover Shareholder will subscribe, and Parent will issue to such Rollover Shareholder, for consideration of $0.0001 per share in cash, the number of ordinary shares of Parent determined as set forth in the Contribution Agreement.

Each Rollover Shareholder has further agreed, with respect to the Rollover Shares beneficially owned by such Rollover Shareholder, to vote (i) in favor of the approval of the Merger Agreement and other actions contemplated by the Merger Agreement and the transactions contemplated thereby and any related action reasonably required in furtherance thereof, (ii) in favor of any matters necessary for the consummation of the transactions contemplated by the Merger Agreement, (iii) against the approval of any alternative acquisition proposal or the approval of any other action contemplated by an alternative acquisition proposal, (iv) against any action, agreement or transaction that is intended, that could reasonably be expected, or the effect of which could reasonably be expected, to materially impede, interfere with, delay or postpone, discourage or adversely affect the transaction contemplated by the Merger Agreement, (v) against any action, proposal, transaction or agreement that would reasonably be expected to result in a breach in any respect of any covenant, representation or warranty or other obligation or agreement of the Issuer contained in the Merger Agreement, or of any Rollover Shareholder contained in the Contribution Agreement, (vi) in favor of any adjournment of any shareholders meeting as may be requested by Parent and (vii) in favor of any other matter necessary to the consummation of the transactions contemplated by the Merger Agreement. In addition, each Rollover Shareholder has agreed that, when a shareholders

meeting of the Issuer is held, to appear at such meeting or otherwise cause its Rollover Shares to be counted as present for purpose of calculating a quorum and ensure any vote at such meeting will be a poll vote. Subject to applicable laws, each Rollover Shareholder has irrevocably appointed Parent as its proxy and attorney-in-fact in connection with the voting of the Rollover Shares beneficially owned by such Rollover Shareholder.

In addition, from the date of the Contribution Agreement until its termination, the Rollover Shareholders will not, directly or indirectly, (i) sell, offer to sell, give, pledge, encumber, assign, grant any option for the sale of or otherwise transfer or dispose of, or enter into any agreement, arrangement or understanding to sell or otherwise transfer or dispose of, an interest in any Rollover Shares (“Transfer”) or permit the Transfer by any of its affiliates of an interest in any Rollover Shares, (ii) enter into any contract, option or other arrangement or understanding with respect to a Transfer or limitation on voting rights of any of the Rollover Shares, or any right, title or interest thereto or therein, (iii) deposit any Rollover Shares into a voting trust or grant any proxy or enter into a voting agreement, power of attorney or voting trust with respect to any Rollover Shares, (iv) take any action that could reasonably be expected to have the effect of preventing, disabling or delaying such Rollover Shareholder from performing its obligations under the Contribution Agreement, or (v) agree (whether or not in writing) to take any of the actions referred to in the foregoing clauses (i) through (iv).

The Contribution Agreement will terminate immediately upon termination of the Merger Agreement.

Limited Guarantee

In connection with the transactions contemplated by the Merger Agreement, on June 8, 2015, Freedom First Holdings Limited, which the Reporting Persons understand is an affiliate of the Founders (the “Guarantor”), entered into a limited guarantee (the “Limited Guarantee”), with the Issuer, pursuant to which the Guarantor irrevocably and unconditionally guaranteed, subject to certain conditions, Parent’s termination fee and certain reimbursement and indemnification obligations of Parent, each under the Merger Agreement. In addition, the Guarantor’s payment obligation under the Limited Guarantee will not exceed $3,250,000. The Limited Guarantee will terminate until the earliest of (i) all of the guaranteed obligations contemplated under the Limited Guarantee have been fully performed, (ii) the consummation of the Merger, (iii) the termination of the Merger Agreement in accordance with its terms in any circumstances other than pursuant to which Parent would be required pursuant to the terms and subject to the conditions of the Merger Agreement to make any payment of an obligation covered by the Limited Guarantee and (iv) the date falling ninety (90) days from the date of the termination of the Merger Agreement in any circumstances pursuant to which Parent would be required to make a payment of an obligation covered by the Limited Guarantee if the Issuer has not presented a bona fide written claim for payment of any guaranteed obligation contemplated under the Limited Guarantee to the Guarantor by such date.

Debt Commitment Letter

In connection with the transactions contemplated by the Merger Agreement, on June 5, 2015, China Merchants Bank Co., Ltd, New York Branch (“CMB”), issued a debt commitment letter (the “Debt Commitment Letter”), which was acknowledged by Parent and the Merger Sub, and pursuant to which, CMB agreed, subject to certain terms and conditions, to arrange and underwrite up to $98 million in the aggregate of debt financing to Parent to consummate the Merger.

The descriptions of the CBC Joinder Agreement, the Merger Agreement, the Contribution Agreement, the Limited Guarantee and the Debt Commitment Letter set forth above in this Item 4 do not purport to be complete and are qualified in their entirety by reference to the full text of each of these agreements, which have been filed as Exhibits 99.3, 99.4, 99.5, 99.6 and 99.7, respectively, and are incorporated herein by reference.

The last paragraph of Item 4 of the Schedule 13D is hereby amended and restated as follows:

Except as indicated above, the Reporting Persons currently do not have any plans or proposals that relate to or would result in any matters listed in Items 4(a)-(j) of Schedule 13D. In addition, each of the Reporting Persons reserves the right to change its plans and intentions in connection with any of the actions discussed in this Item 4, including, among others, the purchase price and the financing arrangement for the transactions contemplated under the Proposal Letter, the Consortium Agreement or the Merger Agreement. Any action taken by the Reporting Persons may be effected at any time and from time to time, subject to any applicable limitations imposed by any applicable laws. No assurance can be given that any definitive agreement or any transaction relating to the Proposed Acquisition will be entered into or be consummated.

Item 5. Interest in Securities of the Issuer

Second paragraph of Item 5 of Schedule 13D is hereby amended and restated as follows:

(a)—(b) The Issuer informed the Reporting persons that as of June 8, 2015, a total of 187,675,080 of its Ordinary Shares were outstanding, comprised of 109,386,066 Class B Ordinary Shares and 78,289,014 Class A Ordinary Shares (excluding 629,502 shares issued to the depositary of the ADSs in anticipation of future exercise of options).

CUSIP No. 86737M100

SCHEDULE 13D

Page 17 of 19

Item 5 of Schedule 13D is hereby supplemented by adding the following:

The calculation of percentages of ownership in this Amendment is based on a quotient obtained by dividing (a) the aggregate number of Class A Ordinary Shares (including the number of Class B Ordinary Shares immediately convertible into Class A Ordinary Shares) beneficially owned by each Reporting Person by (b) the sum of (i) 78,289,014 Class A Ordinary Shares outstanding as of June 8, 2015 (excluding 629,502 shares issued to the depositary in anticipation of future exercise of options) and (ii) the number of Class A Ordinary Shares which such Reporting Person has the right to acquire upon conversion of Class B Ordinary Shares beneficially owned by the Reporting Person or upon the exercise of options or other rights within 60 days after the date hereof.

To the extent that the Reporting Persons are deemed to have formed a group with CBC, the beneficial ownership of the Class A Ordinary Shares by the group would include the beneficial ownership of Class A Ordinary Shares by CBC. As reported by CBC in their Schedule 13G filed with the Commission on April 23, 2014, CBC beneficially owns 20,583,161 Class B Ordinary Shares (which are immediately convertible into Class A Ordinary Shares), which represent 20.8% of the Issuer’s outstanding Class A Ordinary Shares.
