Explanatory Note
This Amendment No. 3 (the "Amendment") amends and supplements the statement on Schedule 13D originally filed by the Reporting Persons on April 13, 2016, as amended by Amendment No. 1 to Schedule 13D filed on April 29, 2016  and Amendment No. 2 to Schedule 13D filed on May 9, 2016 (as amended, the "Schedule 13D"). Capitalized terms used but not otherwise defined in this Amendment shall have the meanings ascribed to such terms in the Schedule 13D. Except as otherwise provided herein, each Item of the Schedule 13D remains unchanged.
ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
Item 3 is hereby supplemented to read as follows:
Since the filing of Amendment No. 2 to the Schedule 13D, the Reporting Persons have purchased 1,140,592 shares of Common Stock for an aggregate consideration of $5,961,139. The source of the funds used to purchase the shares described above is working capital of the Reporting Persons.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

Items 5(a), (b) and (c) are hereby amended and supplemented as follows:
(a)            The aggregate number of shares of Common Stock and the percentage of total outstanding shares of Common Stock beneficially owned by the Reporting Persons is set forth below. The aggregate percentage of shares of Common Stock owned by the Reporting Persons is based upon 120,353,926 shares of Common Stock outstanding as of August 8, 2016, which is the total number of shares of Common Stock outstanding as reported in the Issuer's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 11, 2016.

As of the date of this Amendment, Tsinghua International beneficially owns 8,851,198 shares of Common Stock, which represents approximately 7.35% of the outstanding shares of Common Stock calculated in accordance with the requirements of Rule 13d-3 under the Securities Exchange Act of 1934, as amended.
Tsinghua Capital, as the direct parent company of Tsinghua International, also may be deemed to beneficially own the 8,851,198 shares of Common Stock.
Tsinghua Unigroup, as an indirect, but controlling parent of Tsinghua International, also may be deemed to beneficially own the 8,851,198 shares of Common Stock.
Zhao Weiguo is the Chairman of the Board of Directors of Tsinghua Unigroup and a director of each of Tsinghua Capital and Tsinghua International.  Mr. Zhao expressly disclaims beneficial ownership of the shares of Common Stock beneficially owned by Tsinghua Unigroup, Tsinghua Capital and Tsinghua International.

(b)            Each of Tsinghua Unigroup, Tsinghua Capital and Tsinghua International may be deemed to have shared power to vote and dispose or direct the vote and direct the disposition of an aggregate of 8,851,198 shares of Common Stock.         
(c)            Since the filing of Amendment No. 2 to the Schedule 13D, the Reporting Persons have engaged in certain transactions in the shares of Common Stock as set forth in Annex A and incorporated herein by reference.
