                     GENELABS TECHNOLOGIES, INC. REPORTS

                     FIRST QUARTER 2005 FINANCIAL RESULTS

REDWOOD CITY, Calif. - May 10, 2005 - Genelabs Technologies, Inc.
(Nasdaq:GNLB) today reported revenues of $1.7 million and a net loss of $2.8
million, or $0.03 per share for the first quarter of 2005. This compares to
revenues of $0.7 million and a net loss of $4.8 million, or $0.05 per share
for the first quarter of 2004.

At March 31, 2005, Genelabs had $21.6 million in cash, cash equivalents and
restricted cash.

"Financial results for the first quarter of 2005 were in-line with our
expectations, and we closed the quarter with cash sufficient to fund our
operations approximately into the third quarter of 2006 at our current rate of
spending," stated James A. D. Smith, President and Chief Executive Officer.
"Our drug discovery teams continue to make significant progress as we seek to
discover new treatments for infection with the hepatitis C virus. We are
particularly excited about a chemical class recently discovered by Genelabs
scientists working on our non-nucleoside HCV polymerase program which has
shown exceptional potency. Compounds from this series show potency in our
cell-based assays at concentrations at or below 50 nanomolars and have also
demonstrated favorable drug metabolism and pharmacokinetic properties.
Regarding Prestara(TM), our investigational new drug for lupus, our drug
development team is preparing reports on the results of the recent clinical
trials for a possible meeting with the FDA to discuss the future course of
this project."

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 and clinical development capabilities that can
support various research and development projects. Genelabs is currently
concentrating its capabilities on developing a late-stage product for lupus,
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. 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 information, please visit www.genelabs.com.
