This Amendment No.1 (this “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Persons on December 23, 2015 (the “Original Schedule 13D” and, as amended and supplemented by this Amendment, this “Schedule 13D”). Capitalized terms used in this Amendment and no otherwise defined shall have the same meanings ascribed to them in the Original Schedule 13D.

Item 2. Identity and Background.

This Amendment amends Item 2 of the Original Schedule 13D by replacing Schedule A to the Original Schedule 13D with Schedule A hereto.

Item 4. Purpose of Transaction.

This Amendment amends and supplements Item 4 of the Original Schedule 13D by adding the following:

On March 4, 2016, at 10:00 a.m. (Hong Kong time), an extraordinary general meeting of the shareholders of the Issuer was held at the Issuer’s office at 18/F, Tower 1, U-town Office Building, No. 1 San Feng Bei Li, Chaoyang District, Beijing 100020, the People’s Republic of China. At the extraordinary general meeting, the shareholders of the Issuer voted to authorize and approve the Merger Agreement, the plan of merger substantially in the form attached as Exhibit A to the Merger Agreement (the “plan of merger”) and the transactions contemplated by the Merger Agreement, including the Merger.

On April 8, 2016, the Issuer and Merger Sub filed the plan of merger with the Cayman Islands Registrar of Companies, pursuant to which the Merger became effective on April 8, 2016. As a result of the Merger, the Issuer ceased to be a publicly traded company and became wholly owned by Parent.

At the effective time of the Merger (the “Effective Time”), each Share, including Shares represented by ADSs, issued and outstanding immediately prior to the Effective Time, other than (a) Shares (including Shares represented by ADSs) owned by Parent, Merger Sub or the Issuer (as treasury, if any), or by any direct or indirect wholly-owned subsidiary of Parent, Merger Sub or the Issuer, (b) Shares (including Shares represented by ADSs) reserved (but not yet allocated) by the Issuer for settlement upon exercise or vesting of Company Share Awards (as defined below), (c) Shares owned by shareholders who have validly exercised and have not effectively withdrawn or lost their dissenter rights under Cayman Islands Companies Law (the “CICL”) (the “Dissenting Shares”), and (d) Shares (including Shares issuable under the Company Options (as defined below), the Restricted Shares (as defined below) and Shares represented by ADSs) beneficially owned by the Rollover Shareholders (Shares described under (a) through (d) above are collectively referred to herein as the “Excluded Shares”), has been cancelled in exchange for the right to receive $27.40 in cash per Share without interest and net of any applicable withholding taxes. Each ADS issued and outstanding immediately prior to the Effective Time (other than ADSs representing the Excluded Shares) has been cancelled in exchange for the right to receive $13.70 in cash per ADS without interest and net of any applicable withholding taxes (less $0.05 per ADS cancellation fees pursuant to the terms and conditions of the deposit agreement, dated as of December 8, 2010, by and among the Issuer, Deutsche Bank Trust Company Americas and the holders and beneficial owners from time to time of ADSs issued thereunder, as may be amended from time to time). Each of the Excluded Shares other than Dissenting Shares has been cancelled for no consideration. Each of the Dissenting Shares has been cancelled and each holder thereof is entitled to receive only the payment of the fair value of such Dissenting Shares in accordance with the CICL.

In addition, at the Effective Time, the Issuer terminated the Issuer’s 2009 Stock Incentive Plan and the 2010 Stock Incentive Plan (collectively, the “Share Incentive Plans”), terminated all relevant award agreements entered into under the Share Incentive Plans, and cancelled all options to purchase Shares or ADSs (the “Company Options”) and all restricted shares (the “Restricted Shares”, collectively with the Company Options, the “Company Share Awards”) granted under the Share Incentive Plans that are then outstanding and unexercised, whether or not vested or exercisable.

Page 8 of 14

At the Effective Time, as to the Company Options that are not Rollover Shares: (a) each Company Option vested on or prior to the Effective Time (a “Vested Company Option”) has been cancelled in exchange for the right to receive either a cash amount equal to the excess of $27.40 over the applicable per share exercise price of such Vested Company Option or, as agreed upon by the holder thereof and Parent, an equity incentive award of Parent with substantially the same economic value as such Vested Company Option under the terms to be determined by Parent; (b) each Company Option not vested on or prior to the Effective Time (an “Unvested Company Option”) has been cancelled in exchange for a right to receive an equity incentive award of Parent with substantially the same economic value as such Unvested Company Option under the terms to be determined by Parent. The payment or grant of substituted equity incentive awards in connection with the treatment of applicable Company Options will be made by the surviving corporation or Parent, as applicable, as promptly as practicable following the Effective Time; and (c) each Company Option that is a Rollover Share (whether vested or unvested) has been cancelled in exchange for an option to purchase a number of ordinary shares of Parent (the “Parent Shares”) equal to the number of Shares underlying such Company Option, under the terms to be determined by Parent.

At the Effective Time, as to the outstanding Restricted Shares that are not Rollover Shares: (a) each outstanding Restricted Share vested on or prior to the Effective Time (a “Vested Restricted Share”) has been cancelled in exchange for a right to receive either an equity incentive award of Parent with substantially the same economic value as such Vested Restricted Share under the terms determined by Parent, or as agreed upon by the holder thereof and Parent, $27.40 in cash; (b) each outstanding Restricted Share not vested on or prior to the Effective Time (an “Unvested Restricted Share”) has been cancelled in exchange for a right to receive an equity incentive award of Parent with substantially the same economic value as such Unvested Restricted Share under the terms to be determined by Parent. The payment or grant of substituted equity incentive awards in connection with the treatment of applicable Restricted Shares will be made by the surviving corporation or Parent, as applicable, as promptly as practicable following the Effective Time; and (c) each outstanding Restricted Share that is a Rollover Share (whether vested or unvested) has been cancelled in exchange for a right to receive one Parent Share.

As a result of the Merger, the ADSs will no longer be listed on any securities exchange or quotation system, including the NASDAQ Global Select Market (“NASDAQ”) and the ADS program for the Shares will terminate. The deregistration will become effective 90 days after the filing of the Form 25 or such shorter period as may be determined by the SEC. The Issuer’s reporting obligations under the Act will be suspended immediately as of the filing date of the Form 15 and will terminate once the deregistration becomes effective.

Item 5. Interest in Securities of the Issuer.

This Amendment amends and restates Item 5 of the Original Schedule 13D in their entirety as set forth below:

(a) & (b) The responses of the Reporting Persons to Rows (7) through (13) of the cover pages of this Statement are hereby incorporated by reference in this Item 5. As of the date of this Amendment, the Reporting Persons do not beneficially own any Shares or have any voting power or dispositive power over any Shares.

(c) Except as set forth in Item 4 of this Amendment, none of the Reporting Persons has effected any transactions in the Shares during the past 60 days.

(d) Not Applicable.
