              CELERA GENOMICS TO ACQUIRE AXYS PHARMACEUTICALS, INC.

        MERGER EXPECTED TO ADVANCE DRUG DISCOVERY CAPABILITIES FOR CELERA

ROCKVILLE, MD, and SOUTH SAN FRANCISCO, CA--June 13, 2001--Celera Genomics
(NYSE: CRA), an Applera Corporation business, and Axys Pharmaceuticals, Inc.
(Nasdaq: AXPH), a biopharmaceutical company with expertise in the development of
small molecule therapeutics, announced today that they have signed a definitive
merger agreement whereby Celera will acquire Axys in a stock-for-stock
transaction. The capabilities expected to be acquired through this merger should
support and accelerate Celera's expansion into the drug discovery arena.

The transaction, which has been unanimously approved by the Boards of Directors
of both companies, is structured as a tax-free reorganization and would be
accounted for under the purchase method. Under the terms of the merger
agreement, the ultimate value to be received is subject to a collar mechanism.
(See Additional Information section below.) Based upon Celera's closing stock
price yesterday, Axys stockholders would have receive $4.65 per share payable in
Celera common stock. The transaction is subject to customary closing conditions,
including approval by Axys stockholders and regulatory approvals.

Over the past three years, Celera has established expertise in generating,
integrating, and analyzing genomic data--demonstrating the value of an
industrialized approach to understanding biological processes. This information
has been the basis for Celera's On-line Information Business. Celera is now
leveraging its high-throughput and integrated approaches in bioinformatics,
genomics, and proteomics to create a next-generation diagnostic and therapeutic
company. Axys is expected to complement Celera's existing capabilities,
including its chemical libraries and facilities, high-throughput screening,
medicinal chemistry, structural biology, and pre-clinical capabilities that
should enable Celera to identify and optimize small molecule therapeutic
candidates for its genomic and proteomics discoveries. As part of the planned
merger,

   2

Axys' team of skilled chemists and experienced biologists would be combined with
Celera's scientific teams. In addition to its existing research facilities in
the South San Francisco area, Axys also has a 43,000 square foot,
state-of-the-art medicinal chemistry facility slated for completion this year.

Axys has partnered research and development programs with several pharmaceutical
companies such as Merck & Co., Aventis Pharmaceuticals, Inc., and Bayer AG.
These collaborations address medical conditions such as osteoporosis, asthma,
inflammatory and autoimmune diseases, and cardiovascular disease. Axys' primary
drug discovery research has been directed at proteases--proteins that initiate
key biological processes throughout the body. For the past two years Axys has
focused its internal research efforts on oncology, specifically angiogenesis,
estrogen receptor modulation, tumor metastasis, and apoptosis. Axys has been
successful in applying its structure-based drug design technology platform for
the identification and optimization of clinical candidates.

"As Celera continues its development as a therapeutic and diagnostic company we
will evaluate opportunities necessary to achieve our goals," said Tony L. White,
Applera's chief executive officer. "We believe the merger with Axys is a very
important step in this process. The company has impressive capabilities in
medicinal chemistry, high-throughput screening, and pharmacology that should
enhance Celera's therapeutic discovery platforms. We are also impressed with the
pharmaceutical research partnerships that Axys has established. We believe
Celera will add value to these relationships, and we will continue to look for
other collaborations that could utilize the combined capabilities of Axys and
Celera."

"Building on its genomic and proteomic platform, Celera is now focused on the
identification and evaluation of therapeutic targets that could form the basis
of potential new treatments or cures for human disease," said J. Craig Venter,
Ph.D., Celera's president and chief scientific officer. "Medicinal chemistry and
high-throughput screening capabilities are critical elements to turn these
discoveries into important therapeutic agents and move Celera to the next stage
as a more fully integrated discovery and development company. We look forward to
working together with Axys' impressive integrated chemistry and biology research
teams whose broad technical and industry experience have been successful in
identifying and optimizing small molecule leads. This, coupled with Axys'
research focus in oncology, make for a particularly exciting and synergistic
merger for Celera."

After the planned acquisition is finalized, Michael C. Venuti, Ph.D., Axys'
senior vice president for research and development, will report to Dr. Venter.
Dr. Venuti is an organic chemist with more than 20 years of research experience
in the pharmaceutical and biotechnology industry. His leadership of the
chemistry, structural biology, and preclinical science teams at Axys and their
integration with Celera's scientific organization will be invaluable as Celera
moves toward validation of its promising discoveries. Axys president and chief
executive officer Paul Hastings, with 17 years of pharmaceutical and biotech
commercial management experience will report to Celera's

   3

chief operating office, Peter Chambre. He will play an important role in
integrating Axys' capabilities that expand Celera's ability to commercialize its
therapeutic discoveries.

"In drug discovery, the ultimate validation of a target is demonstrating that
the target can be modulated by a small molecule in a dose-responsive way to
produce a desired therapeutic effect," said Paul Hastings. "In contrast to many
other discovery-oriented biotechnology companies, Axys has been successful in
using a variety of tools to avoid dependence on a single rate-limiting
technology. We are pleased by this merger agreement as we believe that Celera's
volume of therapeutic targets coupled with Axys' drug discovery expertise
focused on employing high throughput screening, medicinal chemistry,
structure-based drug design, and pharmacology directed at preclinical lead
optimization should make for a long-term competitive edge in drug discovery."

ADDITIONAL INFORMATION

The collar mechanism will determine the ultimate exchange ratio delivered to
Axys shareholders based on the average closing price of Celera common stock for
the 10 trading days up until two days prior to closing. The mechanism provides a
fixed exchange ratio of 0.1016 Celera shares per Axys share if the average
Celera price is between (and including) $45.77 to $48.23. Above this fixed band,
there is an upside collar of 25% whereby at average Celera prices of $48.24 to
$60.29 the exchange ratio will fix the transaction value at $4.90 per share by
providing an exchange ratio based on $4.90 divided by the average Celera price.
In no case however shall the exchange ratio be less than 0.0813 (i.e. above an
average Celera price of $60.29, the exchange ratio becomes fixed at 0.0813).
There is a similar downside collar of 25% whereby at average Celera prices of
$45.76 to $34.33 the exchange ratio will fix the transaction value at $4.65 per
share by providing an exchange ratio based on $4.65 divided by the average
Celera price. In no case however shall the exchange ratio be greater than 0.1355
(i.e. below an average Celera price of $34.33, the exchange ration becomes fixed
at 0.1355).
