the Rights Issue

The Rights Issue is on a non-renounceable 1 for 8 basis to raise approximately A$29 million at A$0.60 per ordinary share, and has an incorporated top up facility whereby eligible shareholders may apply for additional new ordinary shares in excess of their entitlement at the same price.

These shares will not be registered under the U.S. Securities Act of 1933, as amended, or any U.S. state securities laws and may not be offered, sold or transferred in the U.S. absent registration or an applicable exemption form registration requirements.

The Record Date for the Rights Issue was 22 May 2006. The ordinary shares to be issued in connection with the Rights Issue are expected to commence trading on the Australian Stock Exchange on 8 June 2006. Applications will close on 7 June 2006.

This document contains forward-looking statements that involve risks and uncertainties. The statements are indicated by the use of words such as "believes", "expects", "anticipates" and similar words and phrases. 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: failure to complete negotiations for new centers for the BrachySil™ phase IIb clinical trial for inoperable primary liver cancer; the failure of our discussions with the FDA for BrachySil™ to continue or to lead to FDA approval; the failure of the BrachySil™ phase IIb clinical trial for inoperable primary liver cancer to determine the optimal dose, provide key safety data or support future pivotal efficacy trials or product registration or approval; failure to commence Phase IIa BrachySilTM trials for the treatment of pancreatic cancer; the failure of the results of the Retisert™ for DME trial to be a good indicator of the results of pSivida’s ongoing Phase III Medidur™ for DME trial; failure of the Medidur trials in DME to show a very similar improvement in visual acuity and diabetic retinopathy severity score as Retisert for DME; inability to recruit patients for the Phase III Medidur™ for DME trial; our failure to develop applications for BioSiliconTM due to regulatory, scientific or other issues, our inability to successfully integrate pSivida Inc’s operations and employees; the failure of the pSivida Inc’s products to achieve expected revenues and the combined entity’s inability to develop existing or proposed products; the failure of the Bausch & Lomb/Novartis co-promotion arrangement to provide faster royalty growth; failure of the slower progression or reduction of diabetic retinopathy resulting from the Retisert™ implant to have significant implications for Retisert™ and Medidur™; failure of our evaluation agreements to result in license agreements; failure of Medidur™ to release the same drug as Retisert™ at the same rate; failure of the Medidur™ trials in DME to show a very similar stabilization or improvement diabetic retinopathy as Retisert™ for DME; failure to achieve cost savings; failure to execute on US growth strategy; failure of the findings of the pancreatic cancer phase IIa trial to provide a platform for further multicentre efficacy and safety trials; failure of there to be optimisation and standardisation between the two  pancreatic cancer study centres; failure of the BrachySil™ primary liver programme that is in Phase IIb clinical trials to provide a valuable platform for the development and commercialisation of BrachySil™ for pancreatic cancer and other indications. Other reasons are contained in cautionary statements in the Annual Report 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.
