EXPLANATORY NOTE

This Amendment No. 5 to Schedule 13D ("Amendment No. 5") is being jointly filed by Dang Yu (George) Pan, Advance Pride International Limited, Wen Liang Li and Wen Wei Ma (collectively, the “Reporting Persons”) as an amendment to that certain Schedule 13D filed by Dang Yu (George) Pan with the Securities and Exchange Commission (the "SEC") on November 13, 2007, as amended by Amendment No. 1 to Schedule 13D filed with the SEC on February 14, 2012, Amendment No. 2 to Schedule 13D filed with the SEC on February 14, 2018, Amendment No. 3 to Schedule 13D filed with the SEC on June 5, 2018 and Amendment No. 4 to Schedule 13D filed with the SEC on March 15, 2019 (collectively, the "Schedule 13D"). Except as amended and supplemented herein, the information set forth in the Schedule 13D remains unchanged. Capitalized terms used herein without definition have meanings assigned thereto in the Schedule 13D.

The first paragraph of (a) — (c) and (f) of Item 2 is amended and restated as follows.

(a) — (c) and (f) This Schedule 13D is filed jointly by the Reporting Persons pursuant to Rule 13d-1(k) promulgated by the SEC under Section 13 of the Act. The Reporting Persons are making this single, joint filing because they may be deemed to constitute a “group” within the meaning of Rule 13d-5(b) under the Act by reason of the Proposal Letter, the Consortium Agreement and the Supplemental Letter as described in Item 4 below. Each Reporting Person (other than Advance Pride) may be deemed to beneficially own the total of 5,118,508 shares of Common Stock beneficially owned by all the Reporting Persons because they may be deemed to constitute a “group.” Each Reporting Person expressly disclaims beneficial ownership of any Common Stock directly or indirectly held by the other Reporting Persons, and does not affirm membership in a “group” (within the meaning of Rule 13d-5(b) under the Act) with the other Reporting Persons, and this Schedule 13D shall not be construed as acknowledging that any of the Reporting Persons beneficially owns any Common Stock directly or indirectly held by the other Reporting Persons or any other person or is a member of a group with the other Reporting Persons or any other person. Information with respect to each of the Reporting Persons is given solely by such Reporting Person, and no Reporting Person assumes responsibility for the accuracy or completeness of the information concerning the other Reporting Persons, except as otherwise provided in Rule 13d-1(k).

Item 4 is supplemented by adding the following:

On April 18, 2019, Mr. Dang Yu (George) Pan submitted a letter (the “Supplemental Letter”) to the special committee of the board of directors of the Issuer (the “Special Committee”). In the Supplemental Letter, Mr. Pan informed the Special Committee that Mr. Pan has formed a consortium with Mr. Wen Liang Li, Mr. Wen Wei Ma and Essence. The Supplemental Letter states that the Proposal Letter thereby is deemed modified to provide, on a non-binding basis, that the Consortium proposes to acquire all the outstanding shares of Common Stock that are not already directly or indirectly beneficially owned by the Consortium in a going private transaction upon the terms and subject to the conditions set forth in the Proposal Letter, and that all other terms and conditions of the Proposal Letter remain unchanged and thereby are reaffirmed. The Consortium also confirmed in the Supplemental Letter that they will not proceed with the Transaction unless it is approved by the Special Committee, taking into account the advice of its independent advisors. The Supplemental Letter further states that the Transaction will be subject to a non-waivable condition requiring the approval by holders of a majority of the outstanding shares of Common Stock not beneficially owned by the Consortium. In addition, the Supplemental Letter states that both Mr. Pan and Mr. Wen Liang Li will recuse themselves from participating in any deliberations and decisions of the board of directors of the Issuer related to the Transaction.

The descriptions of the Supplemental 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 the Supplemental Letter, which has been filed as Exhibit 7.04 to this statement and is incorporated herein by this reference in its entirety.
