                      GENELABS TECHNOLOGIES, INC. REPORTS
                     FIRST QUARTER 2006 FINANCIAL RESULTS

REDWOOD CITY, Calif. - May 15, 2006 - Genelabs Technologies, Inc.
(Nasdaq:GNLB) today reported revenues of $1.7 million and a net loss of $3.4
million, or $0.19 per share, for the first quarter of 2006. This compares to
revenues of $1.7 million and a net loss of $2.8 million, or $0.16 per share,
for the first quarter of 2005.

At March 31, 2006, Genelabs had $7.6 million in cash, cash equivalents and
restricted cash.

"Our hepatitis C virus drug discovery research programs continued to progress
during the first quarter of 2006. Scale-up activities are well underway for
GMP (Good Manufacturing Practices) production of our lead non-nucleoside HCV
polymerase inhibitor, known as compound GL60667. Delivery of this material
would enable us to conduct studies that are necessary for filing a U.S. IND
(Investigational New Drug Application), which we are targeting for next year.
Our NS5a program also continues to progress, and our compounds with potency in
the low-nanomolar range (under 100 nanomolar) are being optimized for better
DMPK (drug metabolism and pharmacokinetic) properties" stated James A.D.
Smith, President and Chief Executive Officer.

"Our Prestara development team has been working with outside lupus experts and
with the FDA and is in the final stages of designing a phase III clinical
trial to support an indication for the treatment of lupus," continued Mr.
Smith. "We plan to conduct this study only if we secure a source of funding
for the trial, which we are currently pursing. I look forward to providing our
shareholders additional updates in the near future."

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 information, please visit www.genelabs.com.
