Starpharma Joins International OTCQX, a New Premium Market Tier for OTC Securities in the U.S.

MELBOURNE, Australia | Posted on March 26th, 2007

International OTCQX provides a gateway to U.S. securities markets by
giving public international companies a vehicle to have their shares traded
in the U.S. and provide ongoing disclosure in English to U.S. investors.
More importantly, International OTCQX distinguishes the reputable
international issuers from the almost 5,000 over-the-counter (OTC)
securities electronically traded on the Pink Sheets. Only leading companies
that have substantial operating businesses and provide credible disclosure
to the public are eligible for inclusion on the premium-tier International
OTCQX, which commenced trading on 5 March 2007.

"This builds on Starpharma's highly successful ADR program, which
already accounts for over 10% of the company's issued stock," said Dr.
Jackie Fairley, CEO of Starpharma.

"The upgrading of Starpharma's Level 1 ADRs to International OTCQX has
a number of advantages as well as providing another tier on our way to
Level 2 ADRs. It will also be accompanied by several new US brokers acting
as market makers for SPHRY," Dr. Fairley added.

Starpharma's ADRs are deposited with the Bank of New York, which was
approved by Pink Sheets on 17 January 2007 as an ADR Principal American
Liaison (PAL) for International OTCQX-listed companies.

"We are delighted to approve Starpharma for our new International
PrimeQX market tier," said Cromwell Coulson, Pink Sheets CEO.
"International OTCQX will make this exciting biotechnology company listed
on the Australian Stock Exchange easily accessible to U.S. Investors."
