DEALING DISCLOSURE

As required under Rule 3.8 of the Takeovers Code, the associates (as defined in the Takeovers Code and including a person who owns or controls 5% or more of any class of relevant securities (as defined in Note 4 to Rule 22 of the Takeovers Code)) are hereby reminded to disclose their dealings in any securities of the Company pursuant to the requirements of the Takeovers Code.

In accordance with Rule 3.8 of the Takeovers Code, reproduced below is the full text of Note 11 to Rule 22 of the Takeovers Code:

‘‘Responsibilities of stockbrokers, banks and other intermediaries

Stockbrokers, banks and others who deal in relevant securities on behalf of clients have a general duty to ensure, so far as they are able, that those clients are aware of the disclosure obligations attaching to associates and other persons under Rule 22 and that those clients are willing to comply with them. Principal traders and dealers who deal directly with investors should, in appropriate cases, likewise draw attention to the relevant Rules. However, this does not apply when the total value of dealings (excluding stamp duty and commission) in any relevant security undertaken for a client during any 7 day period is less than $1 million.

This dispensation does not alter the obligation of principals, associates and other persons themselves to initiate disclosure of their own dealings, whatever total value is involved.

Intermediaries are expected to co-operate with the Executive in its dealings enquiries. Therefore, those who deal in relevant securities should appreciate that stockbrokers and other intermediaries will supply the Executive with relevant information as to those dealings, including identities of clients, as part of that co-operation.’’

‘‘Executive’’ referred to above has the meaning ascribed to it under the Takeovers Code.

Shareholders and potential investors need to be aware that no binding agreement has been entered into in relation to a Possible Transaction. Accordingly, there is no certainty that any transaction would be concluded at the price currently under discussion or at any price or that would result in the change in control of the Company will materialize or ultimately be consummated. Shareholders and potential investors are urged to exercise caution when dealing in the shares of the Company.
