EXHIBIT A

Class A Preference Shares

1.               No economic right and no right to dividend or any other distribution of the Company (except a right to return of par value of US$1.00 per share on a winding up of the Company pari passu with Ordinary Shares).

2.               Class A Preference Shares are not convertible into Ordinary Shares.

3.               Special voting rights:

(i)                                      Class A Preference Shares are entitled to vote on all matters submitted to a general meeting of the Company.  Each Class A Preference Share is entitled to 10,000 votes initially.  When New Wave MMXV Limited (“ New Wave ”) sells or otherwise transfers any number of Ordinary Shares to a third party which is not an affiliate of New Wave, the number of votes that each Class A Preference Share is entitled to shall be reduced by a ratio that equals to the number of Ordinary Shares sold or transferred divided by 7,944,386 1 .  For illustration purpose, if New Wave sells 1,000,000 Ordinary Shares, each Class A Preference Shares shall be entitled to 8,741 votes (being the result of 10,000 x (1 - 1,000,000 / 7,944,386)).

(ii)                                   On any resolution to elect a Director where the nominee is a person holding executive office in the Company, then if a majority of the votes cast by the holders of the Ordinary Shares is against the appointment of such nominee, then the votes attaching to the Class A Preference Shares on such resolution shall not be counted and the Class A Preference Shares shall be disenfranchised on such resolution in this circumstance.

(iii)                                For all matters that are required to be subject to shareholder approval under Rule 5635 of the Nasdaq Stock Market Rules, New Wave shall vote Class A Preference Shares in accordance with the Company board’s recommendation to the extent the board determines to submit any such matter to a general meeting of the Company to seek shareholder approval.

(iv)                               If New Wave transfers the Class A Preference Shares to a third party which is not an affiliate of New Wave, or when New Wave ceases to be controlled by any person holding executive office in the Company, Class A Preference Shares shall cease to have any voting right.

(v)                                  Determination as to whether an entity is an “affiliate” of New Wave or is controlled by any person holding executive office in the Company shall be made in accordance with the definition of “affiliate” under relevant US securities law and rules promulgated thereunder as well as related cases.

1   Represent the number of ordinary shares of the Company held by New Wave as of the date hereof.
