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, 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 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).
