--Company Increases Increlex 2007 Revenue Guidance--

BRISBANE, Calif. -- Tercica, Inc. (Nasdaq:TRCA) today announced financial results for the quarter ended June 30, 2007. Net product sales totaled $2.0 million, compared to $166,000 in the second quarter of 2006. Net loss for the quarter was $12.8 million, or $0.26 per share, compared to a net loss of $14.7 million, or $0.39 per share, for the second quarter of 2006.

Cash, cash equivalents and short-term investments as of June 30, 2007 were $98.0 million, compared to $110.7 million as of March 31, 2007.

Financial Guidance

Tercica had previously guided that Increlex([R]) 2007 revenues would be approximately $7-$8 million. Based on results to date, Tercica now expects that Increlex([R]) 2007 revenues will be approximately $9-$10 million. Assuming receipt of an approximate EU15 million European-approval milestone payment for Increlex([R]) and issuance to Ipsen of a Somatuline([R]) Autogel([R]) approval-related convertible note of $15 million for cash, Tercica now expects to end 2007 with $100-$105 million in cash.

"The second quarter was very productive for Tercica. Increlex quarter-over-quarter revenues increase continues to accelerate, allowing us to raise our 2007 revenue guidance. In July, we announced an important collaboration with Genentech to develop two next-generation growth hormone products with the potential to capture a significant share of, and possibly expand, the $2.5 billion growth hormone market," said John A. Scarlett, M.D., Tercica's President and Chief Executive Officer. "Our next major milestone is the August 30, 2007 PDUFA date for Somatuline Autogel, followed by its U.S. launch subject to FDA approval," added Dr. Scarlett.
