INSIDER TRADING.

It is against the law to trade in Mercury shares where you have information that is not generally available to the market; and if it were generally available to the market, a reasonable person would expect it to have a material effect on the price of Mercury shares. This is called insider trading, and is always prohibited.

WHAT THIS MEANS FOR YOU:

• Understand the restrictions you have on trading if you possess ‘material information’ and other requirements in the Trading in Company Securities Policy

• ‘Restricted Persons’ are identified by their role as likely to have access to material information. If you are a restricted person, you will be notified of this, and, of ‘blackout’ periods when you must not trade Mercury shares.

• If you are a Restricted Person and you wish to buy or sell Mercury shares you must, in writing: notify the Company Secretary of your intention to trade; confirm that you don’t hold material information; and confirm that there is no known reason to prohibit trading in any Company Securities. The Company Secretary may refuse your request.
