ADSs Slated to Commence Trading
Citigroup selected as Depositary Bank for National Market Level II ADR

Global nanotechnology company pSivida Limited (ASX: PSD), is pleased to announce that its U.S. securities registration has been declared effective and it has received preliminary approval from NASDAQ for the listing of its American Depositary Shares (ADSs) represented by American Depositary Receipts (ADRs) on the NASDAQ National Market. The Company has also selected Citigroup as it Depositary Bank to administer the ADR programme.

pSivida expects its ADSs to commence trading on NASDAQ’s National Market on Thursday 27th January 2005 under the ticker symbol PSDV. The ADSs will trade on a 10:1 ratio to the Company’s ordinary shares (i.e., 10 pSivida shares for every 1 ADR). pSivida’s ordinary shares will continue to trade on the Australian and Frankfurt Stock Exchanges.

pSivida Managing Director, Mr. Gavin Rezos said, “The NASDAQ listing will be an important step forward for pSivida as it looks to achieve success in the world’s largest market in terms of capital and pharmaceutical products. We are actively looking to expand our investor base in the U.S. and are very pleased to appoint Citigroup as our Depositary Bank.”

The appointment of Citigroup Depositary Receipt Services provides pSivida with a gateway to the resources of Citigroup and the means to diversify its shareholder bases and increase liquidity.

Importantly the listing will offer access to U.S. investors that are currently prohibited or limited in owning foreign securities or who only invest in companies that publish results computed in accordance with US GAAP.

American Depository Receipts (ADRs)

ADRs are commonly used to facilitate US investors investing in foreign companies which do not directly list their securities in the U.S. Some US investors, particularly certain domestic mutual funds, are prohibited from investing directly in foreign securities, and ADRs which are issued by a U.S. Depositary Bank provide a mechanism for them to invest in foreign securities.

An ADR is created when a broker purchases the Company’s shares on the home stock market and delivers those shares to the Depository Bank to issue Depository Receipts.

For additional information regarding the terms of our ADSs, please see our registration statement.

A registration statement relating to these securities has been filed with the Securities Exchange Commission. This press release shall not constitute an offer to sell or the solicitation of an offer to buy any securities. You should refer to our registration statement for more complete information concerning the company and its business. The registration statement is available at the SEC's website: www.sec.gov.

This document contains forward-looking statements that involve risks and uncertainties including with respect to the the commencement of trading of pSivida's ADSs, the expansion of pSivida's investor base in the U.S. and the development and commercialisation of BioSilicon. Although we believe that the expectations reflected in such forward-looking statements are reasonable at this time, we can give no assurance that such expectations will prove to be correct. Given these uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Actual results could differ materially from those anticipated in these forward-looking statements due to many important factors including: regulatory issues involving the SEC and/or the NASDAQ Stock Market, including without limitation the SEC or NASDAQ reopening review of pSivida's registration statement or listing application; pSivida's failure to take the remaining steps necessary to complete the listing on the NASDAQ National Market, including pSivida's inability to meet NASDAQ's initial or continuing listing requirements. In addition, investors may not purchase ADSs on the market and an active trading market for the ADSs may not develop or be maintained after listing. Further, many important factors could negatively impact pSivida's business results including: (1) the failure of certain product markets to develop as expected including due to global economic conditions or alternate remedies being discovered; (2) the company's failure to complete its current or future clinical trials successfully because of problems with funding, the performance of its product or its partners; (3) the company's failure to achieve product approvals on a timely basis if at all as a result of regul atory, funding or other issues and (4) the failure of the company's current and potential products to perform as expected due to unknown factors involving their use. Other reason are contained in cautionary statements in the Registration Statement on Form 20-F filed with the U.S. Securities and Exchange Commission, including, without limitation, under Item 3.D, "Risk Factors" therein. We do not undertake to update any oral or written forward-looking statements that may be made by or on behalf of pSivida.
