"THE FIGHT TO ACE CANCER"

Cancer survivor Corina Morariu returns at full-strength to US Open competition

Nutley, New Jersey (August 22, 2003) - Hoffmann-La Roche (Roche) today announced its plans to kick off a new cancer research fundraiser, "The Fight to Ace Cancer," during this year's US Open Tennis Championships beginning August 25th in Flushing, NY. The highlight of the event will be the participation of cancer survivor Corina Morariu, who will be making her return to the tournament at full-strength after battling acute promyelocytic leukemia (APL). For every ace that Corina serves during the tournament, Roche will donate $1,000 to Friends of Cancer Research to help advance programs aimed at the treatment and prevention of cancer.

"Roche is committed to cancer research and treatment innovation and we couldn't think of a better person to represent this program than Corina Morariu," said Lars Birgerson, M.D., Ph.D. Vice President, Medical Affairs at Roche. "Corina is a true survivor and the inspiration behind Fight to Ace Cancer. We hope to not only raise awareness of the triumphs and struggles of people living with cancer, but also to emphasize the importance of cancer research."

Just one year after she reached the status of No. 1 women's doubles player in the world and two years after winning the Wimbledon doubles championship with Lindsay Davenport, Corina - at age 23 - was diagnosed with acute promyelocytic leukemia (APL). A rare form of leukemia resulting in a malignancy of bone marrow, Corina was forced to put her tennis career on hold and undergo intense chemotherapy treatment. Amazingly, Corina went into remission within 14 months of her diagnosis and start of therapy, and, since then, she has become an advocate for cancer research and education throughout the country. She is dedicating her play in this year's US Open to cancer survivors and their families.

"I owe my life to the efforts of people who raise money for cancer research and to pharmaceutical companies like Roche who develop innovative medicines. I am finally back playing competition tennis this year and want to do everything I can to help other cancer survivors," said Morariu. "If it weren't for the generosity of others, I wouldn't be here today continuing to play tennis and living out my dreams. So, I'm proud to be part of the Fight to Ace Cancer."

"We are honored to partner with Corina and Roche in a unique collaboration that underscores the critical need to support cancer research," said Ellen V. Sigal, PhD, Chairperson of Friends of Cancer Research, a not-for-profit located in Washington DC that provides public education on cancer research in order to accelerate national progress towards cancer prevention and treatment. "Fight to Ace Cancer will assist our public awareness and funding efforts while celebrating the courage of an extraordinary young athlete for whom innovative cancer research has spelled hope and a return to competitive tennis," Dr. Sigal added.
