09:37 MB-HSBC @EC0603<04919> - Announcement (2) Prospective purchasers of Warrants should be aware that the price of Warrants may fall in value as rapidly as they may rise and prospective purchasers should be prepared to sustain a total loss of the purchase price of their Warrants. In choosing to deal in the Warrants a prospective purchaser should consider carefully whether the Warrants are suitable for him/her in light of his/her experience, objectives, financial position and other relevant circumstances. The Issuer has appointed Macquarie Equities (Asia) Limited of 19th Floor, Citic Tower, 1 Tim Mei Avenue, Central, Hong Kong, (Broker ID Number 9599) as liquidity provider (the "Liquidity Provider") by responding to requests for bid and offer quotes for the purpose of making a market in the Warrants. A request for a quote may be obtained by calling the telephone number 2823 3788. Prospective purchasers of the Warrants should be aware that such appointment does not guarantee liquidity in the market in the Warrants, further, the Liquidity Provider may be the only market maker for the Warrants and the secondary market in the Warrants may therefore be limited. Based on the Issuer's own calculations and information, implied volatility of the Warrants was 13.50%, effective gearing was 12.25x, gearing was 32. 60x and premium was 5.83%. It should be noted that the above values should not be compared to similar information provided by other derivative warrant issuers as different issuers adopt different valuation models. The Issuer may enter into discount, commission or fee arrangements with brokers and/or any of its affiliates with respect to the primary and/or secondary market in the Warrants. In respect of the Warrants, the Issuer has entered into arrangements where it will agree to pay commission of up to 1.00% to certain brokers on behalf of clients of the relevant brokers. Such arrangements may result in a benefit to persons buying and selling the Warrants through nominated brokers by reducing the commission that would have been paid directly by such holders of the Warrants. The Issuer is regulated by the Australian Prudential Regulation Authority and is not regulated by any of the bodies referred to in Rules 15A.13(2) or (3) of the Listing Rules. The Issuer does not carry on banking business in Hong Kong. It is not an Authorised Institution under the Banking Ordinance (Chapter 155 of the Laws of Hong Kong) and therefore is not subject to the supervision of the Hong Kong Monetary Authority. 6 May 2005 Macquarie Bank Limited
