THE BOARD OF DIRECTORS RECOMMENDS

THE RE-ELECTION OF EACH OF THE CURRENT DIRECTORS NAMED ABOVE.

BOARD OF DIRECTORS AND BOARD COMMITTEES

Our Board of Directors currently consists of five directors, including two executive directors and three independent directors. We have also established an Audit Committee, a Nominating and Corporate Governance Committee and a Compensation Committee. We have adopted a charter for each of the three committees. Each of the committees of our Board of Directors shall have the composition and responsibilities described below.

Terms of Directors

Our directors are not subject to a set term of office and hold office until the next general meeting called for the appointment of directors and until their successor is duly appointed or such time as they die, resign or are removed from office by a shareholders’ ordinary resolution. The office of a director will be vacated automatically if, among other things, the directors resigns in writing, becomes bankrupt or makes any arrangement or composition with his/her creditors generally or is found to be or becomes of unsound mind.

Duties of Directors

Under Cayman Islands law, directors owe the following fiduciary duties:

(i)duty to act in good faith in what the director or officer believes to be in the best interests of the company as a whole;

(ii)duty to exercise powers for the purposes for which those powers were conferred and not for a collateral purpose;

(iii)directors should not properly fetter the exercise of future discretion;

(iv)duty to exercise powers fairly as between different sections of shareholders;

(v)duty not to put themselves in a position in which there is a conflict between their duty to the company and their personal interests; and

(vi)duty to exercise independent judgment.

In addition to the above, directors also owe a duty of care which is not fiduciary in nature. This duty has been defined as a requirement to act as a reasonably diligent person having both the general knowledge, skill and experience that may reasonably be expected of a person carrying out the same functions as are carried out by that director in relation to the company and the general knowledge skill and experience which that director has.

As set out above, directors have a duty not to put themselves in a position of conflict and this includes a duty not to engage in self-dealing, or to otherwise benefit as a result of their position. However, in some instances what would otherwise be a breach of this duty can be forgiven and/or authorized in advance by the shareholders provided that there is full disclosure by the directors. This can be done by way of permission granted in the amended and restated memorandum and articles of association or alternatively by shareholder approval at general meetings.

Accordingly, as a result of multiple business affiliations, our directors may have similar legal obligations relating to presenting business opportunities meeting the above-listed criteria to multiple entities. In addition, conflicts of interest may arise when our Board of Directors evaluates a particular business opportunity with respect to the above-listed criteria. We cannot assure you that any of the afore-mentioned conflicts will be resolved in our favor. Furthermore, each of our directors has pre-existing fiduciary obligations to other businesses of which they are directors.

Our company has the right to seek damages if a duty owed by our directors is breached. A shareholder may in certain limited exceptional circumstances have the right to seek damages in our name if a duty owed by our directors is breached.
