                        GENELABS ANNOUNCES COLLABORATION
                      FOR DEVELOPMENT AND COMMERCIALIZATION
                      OF HCV NON-NUCLEOSIDE DRUG CANDIDATES

REDWOOD CITY, Calif. - June 5, 2006 - Genelabs Technologies, Inc. (Nasdaq:GNLB)
announced today that it has entered into a license and collaboration agreement
with Novartis for the development and commercialization of compounds from
Genelabs' Hepatitis C Virus (HCV) non-nucleoside drug discovery program.

"I am delighted that Genelabs and Novartis are entering into this collaboration.
This collaboration links us with a partner that has the scope, scale, expertise
and commitment to make a major impact on the future treatment of HCV infection,"
stated James A.D. Smith, President and Chief Executive Officer. "The Genelabs
non-nucleosides covered by this collaboration have the potential to be
complementary with other HCV drugs being developed by Novartis, and I believe
Novartis is well positioned to move this project forward efficiently."

Under the terms of the agreement, Genelabs is eligible to receive approximately
$20 million over a planned two-year research program, including initial up-front
payments of $12.5 million. If all potential clinical, regulatory and sales
milestones are met, additional payments to Genelabs could exceed $175 million.
Genelabs is also entitled to a royalty on net sales of products covered by the
collaboration.

"This is the second major collaboration for Genelabs based on our HCV drug
discovery platform, and we are very pleased to have Novartis as our partner,"
stated Ronald C. Griffith, Ph.D., Chief Scientific Officer. "I am proud of the
highly skilled and dedicated scientists working at Genelabs, who have all
contributed to our HCV drug discovery successes."

About the Hepatitis C Virus

Hepatitis C is a viral liver disease caused by infection with the Hepatitis C
Virus. Worldwide, 170 million people are estimated to be infected with the

About Genelabs Technologies
- ---------------------------
Genelabs Technologies, Inc. is a biopharmaceutical company focused on the
discovery and development of pharmaceutical products to improve human health. We
have built drug discovery capabilities that can support various research and
development projects. Genelabs is currently concentrating these capabilities on
discovering novel compounds that selectively inhibit replication of the
hepatitis C virus and advancing preclinical development of compounds from this
hepatitis C virus drug discovery program, while also developing a late-stage
product for lupus. We believe that these high-risk, potentially high reward
programs focus our research and development expertise in areas where we have the
opportunity to generate either first-in-class or best-in-class products that
will address diseases for which current therapies are inadequate. For more
