Capitalized terms used but not defined in this Amendment No. 4 shall have the meanings assigned to such terms in the Schedule 13D.

ITEM 4.

PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

On February 26, 2016, an extraordinary general meeting of the shareholders of the Company was held at 11:00 a.m. (Hong Kong time) at FLAT/RM 15-16 BLK 1 11/F, Grand Century, 193 Prince Edward West Road, Mongkok KL, Hong Kong. At the extraordinary general meeting, the shareholders of the Company authorized and approved the Merger Agreement (as amended by Amendment No. 1 to the Merger Agreement), the plan of merger required to be filed with the Registrar of Companies of the Cayman Islands, substantially in the form attached as Annex A to the Merger Agreement (the “Plan of Merger”) and the transactions contemplated thereunder, including the Merger.

On March 3, 2016, the Company and Merger Sub filed the plan of merger with the Cayman Islands Registrar of Companies, which was registered by the Cayman Islands Registrar of Companies as of March 3, 2016, pursuant to which the Merger became effective on March 3, 2016. As a result of the Merger, the Company ceased to be a publicly traded company and became a wholly-owned subsidiary of Parent.

At the Effective Time, each Ordinary Share issued and outstanding immediately prior to the Effective Time was cancelled in exchange for the right to receive US$28.0 and each ADS, representing one Ordinary Share, was cancelled in exchange for the right to receive US$28.0 (less US$0.05 per ADS cancellation fees), in each case, in cash, without interest and net of any applicable withholding taxes, except for (a) the Ordinary Shares and ADSs beneficially owned by the Rollover Shareholders, which were cancelled and ceased to exist without payment of any consideration or distribution therefor and (b) Ordinary Shares outstanding immediately prior to the Effective Time and held by holders who have validly given a written objection with respect to the Merger pursuant to Section 238(2) of the CICL and not withdrawn or lost their dissenter’s rights pursuant to the CICL, which were cancelled and ceased to exist in exchange for the right to receive payment of the fair value of such Ordinary Shares as determined in accordance with the CICL.

In addition, at the Effective Time, the Company’s 2006 Employee Share Incentive Plan and the Company’s Amended and Restated Limited Share Incentive Plan, and all amendments and modifications thereto (collectively, the “Share Incentive Plans”) and any relevant awards agreements applicable to the Share Incentive Plans were terminated. At the Effective Time, except with respect to the Rollover Shareholders, (i) each outstanding and unexercised option to purchase Ordinary Shares under the Share Incentive Plans (a “Company Option”) was cancelled in consideration and exchange for the right to receive as soon as practicable following the Effective Time the right to receive a cash amount equal to the excess of US$28.0 over the exercise price of such Company Option, without interest and net of any applicable withholding taxes; (ii) each outstanding and unexercised Company Option was cancelled without any payment therefor if the exercise price of such Company Option was equal to or greater than US$28.0; (iii) each outstanding restricted share award under the Share Incentive Plans (a “Restricted Share”) and each outstanding restricted share unit under the Share Incentive Plans (an “RSU”) that was vested on or prior to January 1, 2016 was cancelled in consideration and exchange for the right to receive US$28.0 in cash, without interest and net of any applicable withholding taxes; (iv) each outstanding Restricted Share and each RSU that was not vested on or prior to January 1, 2016 and was held by members of the Special Committee was cancelled in consideration and exchange for the right to receive US$28.0 in cash, without interest and net of any applicable withholding taxes; and (v) each outstanding Restricted Share and each RSU that was not vested on or prior to January 1, 2016 and was not held by members of the Special Committee was cancelled in consideration and exchange for the right to receive an RCA of $28.0 in cash upon vesting of such RCA, without interest and net of any applicable withholding taxes (the Company as the surviving corporation after the Merger shall pay each holder 50% of his or her RCAs on January 1, 2017 and the remaining 50% on January 1, 2018, except for the payment to holders who are U.S. taxpayers, which payment shall be made in accordance with the payment timing of the settlement provisions of the related RSU award agreements).

Upon the consummation of the Merger, the Company became a wholly-owned subsidiary of Parent and the separate corporate existence of Merger Sub ceased. As a result of the Merger, the ADSs will cease to trade on the New York Stock Exchange (the “NYSE”) following the close of trading on March 4, 2016 and will become eligible for delisting from the NYSE and termination of registration pursuant to Rules 12g-4(a)(1) and 12h-3(b)(1)(i) of the Securities Exchange Act of 1934, as amended.

Pursuant to the Support Agreements each entered into by each Rollover Shareholder with Parent and Holdco, the securities owned by the Rollover Shareholders were cancelled at the closing of the Merger, and the Rollover Shareholders subscribed for newly issued ordinary shares of Holdco. The information disclosed in this paragraph is qualified in its entirety by reference to the Support Agreements, copies of which were filed as Exhibit 7.06 through Exhibit 7.08 to the Schedule 13D.

ITEM 5.

Interests in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) – (b) As of the date of this Amendment No. 4, the Reporting Persons do not beneficially own any Ordinary Shares or have any voting power or dispositive power over any Ordinary Shares.

(c) The last paragraph in Item 4 of this Amendment No. 4 is incorporated herein by reference and is qualified in its entirety by reference to the Support Agreements, copies of which were filed as Exhibit 7.06 through Exhibit 7.08 of the Schedule 13D.
