MELBOURNE, Australia and MENLO PARK, Calif., June 27 /PRNewswire- FirstCall/ -- ChemGenex Pharmaceuticals Limited announced today that it has received approval from the NASDAQ to list its securities on the NASDAQ SmallCap Market as American Depositary Receipts (ADRs) under the ticker CXSP. Trading in ChemGenex ADRs will be possible from Tuesday June 28, 2005 at 9.30 am EDT (US time).

Each ADR will represent 15 ordinary shares. The ordinary shares will continue to trade on the Australian Stock Exchange under the ASX code "CXS". The Company has selected the Bank of New York to administer its ADR program.

"This is an important step in the growth of ChemGenex as an international pharmaceutical company" said Greg Collier, Ph.D., Chief Executive Officer and Managing Director of ChemGenex Pharmaceuticals. "Listing on NASDAQ enables access to US capital markets. ChemGenex has developed a significant US presence over the past year, with executive and clinical development staff in our US office and two ongoing Phase 2 clinical trials in major US cancer centres. We believe that we are well-positioned to grow our investor base in the US, and are confident that a NASDAQ-listing will assist us in this regard."

American Depository Receipts (ADRs)

ADRs are commonly used to facilitate US investors investing in foreign companies not listed the US. Some US investors, particularly certain domestic mutual funds, are prohibited from investing directly in foreign securities and ADRs 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.

ChemGenex is undertaking a Level 2 ADR program, which requires the preparation of a Registration Statement which is submitted to the US Securities and Exchange Commission (SEC) which when completed provides a listing with US GAAP and full SEC compliance.


ChemGenex ADSs will trade on the fully automated, screen based NASDAQ SmallCap Market.
