CYTOGEN TO ACQUIRE ADVANCED MAGNETICS
STRATEGIC MERGER STRENGTHENS CYTOGEN'S ONCOLOGY PRESENCE, AS
WELL AS PROVIDING PRODUCT, TECHNOLOGY AND CASH
RESOURCES
Princeton, NJ and Cambridge, Ma - July 10, 2000 - Cytogen Corporation (Nasdaq:
CYTO) and Advanced Magnetics, Inc. (AMEX: AVM) today jointly announced that they
have entered into a definitive merger agreement under which Cytogen will acquire
Advanced Magnetics, a developer of novel diagnostic pharmaceuticals for use in
magnetic resonance imaging (MRI). The transaction represents a strategic step
for Cytogen to broaden its oncology franchise, which it intends to leverage
through its proteomics business and the development of products using its
prostate specific membrane antigen (PSMA) technology. The two companies believe
that this stock-for-stock transaction, which includes products, technology, and
cash assets, is in the best interests of the shareholders of both companies and
provides the combined company with the following benefits:
o The acquisition broadens Cytogen's medical oncology presence and strengthens
its position in the area of cancer staging and detection, in which Cytogen
currently markets two products, ProstaScint(R), a prostate cancer imaging
agent, and OncoScint CR/OV(R), an imaging agent for ovarian and colorectal
cancers.
o Advanced Magnetics' near-term product, Combidex(R), a MRI contrast agent for
the detection of lymph node metastases, has produced promising clinical
results and creates the potential for an enhanced revenue stream. The U.S.
Food and Drug Administration (FDA) recently issued an approvable letter with
respect to Combidex, following a priority review.
o The combined company plans to utilize Cytogen's oncology sales and marketing
organization for the expected launch of Combidex in the first half of 2001.
o At March 31, 2000, Advanced Magnetics had $19.5 million in cash and
marketable securities. The enhanced cash position created by the merger
secures development resources and provides leverage to other areas of the
combined business, including prostate cancer diagnostics and therapeutics
based on PSMA technology and Cytogen's AxCell Biosciences proteomics
subsidiary.

o The combined development teams, which have been responsible for a total of
five FDA approved products to date, will apply their expertise to obtaining
and maintaining regulatory approvals and accelerating the commercial
introduction of product candidates in the pipeline. One such product
candidate is Advanced Magnetics' next-generation imaging agent, Code 7228,
which is scheduled to enter Phase II clinical development later this year.
Code 7228 is being developed for oncology and magnetic resonance angiography
applications.
o Cytogen gains cutting-edge, iron oxide-based imaging technology as well as a
state-of-the-art manufacturing facility, and a patent portfolio consisting of
25 U.S. patents and additional U.S. and foreign pending patent applications.
Cytogen plans to use Advanced Magnetics' Cambridge, Massachusetts, GMP
facility for fill, finish, and distribution of two of Cytogen's existing
products, ProstaScint and OncoScint CR/OV imaging agents.
Under the terms of the agreement, Cytogen will acquire all of Advanced
Magnetics' outstanding stock in a tax-free, stock-for-stock transaction
structured as a pooling of interests. Advanced Magnetics' shareholders will
receive $60 million in shares of Cytogen common stock. Each outstanding Advanced
Magnetics common share will be converted into $8.75 market value of Cytogen
common shares, subject to a collar on the price of Cytogen common stock ranging
from $8.55 to $11.56. The transaction is subject to approval by Advanced
Magnetics' shareholders and is expected to close in the third quarter of 2000.
"By growing Cytogen via a strategic, synergistic acquisition, we are aiming to
leverage the value of our existing assets and expertise to increase shareholder
value," said H. Joseph Reiser, Ph.D., Cytogen's Chief Executive Officer. "This
acquisition fits well with our continuing strategy to introduce specialized
cancer products that aid physicians in the diagnosis and staging of various
cancers using novel physiological targeting approaches. Since lymph nodes are
often the first sites to which cancer spreads from the primary tumor, such
staging information is critical in making the best treatment decisions. The
Advanced Magnetics acquisition goes hand in glove with our present prostate
cancer product and related development efforts, and their near-term product,
Combidex, could allow us to build a leading company in lymph-node-based cancer
staging and diagnosis. We estimate that in the broader oncology field there are
over 800,000 cancer patients in the United States who may benefit from lymph
node imaging."
"Advanced Magnetics' working capital should provide the combined company with
ready funding for the commercialization of Combidex, assuming final approval is
granted," added Dr. Reiser. "With the combined expertise of the two management
teams, we believe that we could be in a stronger position to accelerate other
corporate goals related to the development of immunotherapies, the acquisition
of new products, and the further acceleration of our proteomics initiative at
our wholly owned subsidiary, AxCell BioSciences."
"Cytogen provides a logical strategic fit for Advanced Magnetics' products and
personnel," said Jerome Goldstein, Chairman and CEO of Advanced Magnetics.
"Advanced Magnetics' technology and products have the potential to achieve
greater market penetration under the Cytogen umbrella than they do alone.
Therefore, I believe that the combination of the two companies is in the best
interests of both groups of

shareholders. In addition, the timing of this transaction is ideal. We recently
received an initial action letter from the FDA indicating that our Combidex MRI
contrast agent for imaging of metastatic lymph nodes was `approvable,' subject
to certain conditions being satisfied. We believe the combined company will be
well positioned to launch and market this product to oncologists upon
anticipated final approval, given our combined experience in the oncology
marketplace with metastatic cancer detection and Cytogen's recent deployment of
a dedicated oncology sales force."
