Unusual Price Fluctuations

2.6 If the market price of Listed Shares has increased or decreased dramatically in a

relatively short period of time and the price change does not appear to be the result of

fully disclosed Material Information relating to the affairs of the Issuer, the Regulation

Services Provider will halt trading in the Listed Shares “pending clarification of the

market activity.”

2.7 The review procedures which the Regulation Services Provider will employ in the case of

unusual price fluctuations have been designed to:

(a) ensure that all Material Information concerning the change(s) in question has been

accurately disclosed;

(b) ascertain if there have been, or there are, trading irregularities in the stock;

(c) ascertain if there has been any inappropriate or undisclosed Investor Relations

Activities relating to the Issuer; and

(d) ascertain the adequacy of the public distribution of the stock.

2.8 After completing its review, the Regulation Services Provider will take such steps as it determines appropriate, including requiring the Issuer to issue a further news release or referring the matter to the Exchange for further handling.
