OXiGENE Reports Fourth-Quarter and Year-End 2003 Financial Results;
Sets 2004 Milestones

    WALTHAM, Mass.--(BUSINESS WIRE)--Feb. 12, 2004--OXiGENE, Inc.
(NASDAQ: OXGN) (XSSE: OXGN):

    Accomplishments in 2003:

    --  Lead Compound Enters Four New Cancer Trials

    --  CA4P Becomes First Vascular Targeting Agent Tested in
        Ophthalmology

    --  Company Plans for Major Expansion of Ophthalmology Program

    --  CA4P Granted Fast Track and Orphan Drug Designation in Certain
        Thyroid Cancers

    --  Company Strengthens Balance Sheet

    OXiGENE, Inc. (NASDAQ: OXGN) (XSSE: OXGN), a leading developer of
biopharmaceutical compounds designed to target aberrant blood vessels
within solid tumor cancers and ocular neovascular diseases, today
reported financial results for the fourth quarter and year ended
December 31, 2003.
    "By any measure, 2003 was the most successful year in OXiGENE's
history," said President and Chief Executive Officer Fred Driscoll.
"We advanced Combretastatin A4 Prodrug (CA4P) into a total of five new
human clinical trials in the United States and Europe, and broadened
its therapeutic use into two very large disease areas with unmet
medical needs - cancer and ophthalmology. The year also was
highlighted by key regulatory milestones as CA4P secured the U.S.
FDA's fast track designation and orphan drug status in certain thyroid
cancers. Including the $24.2 million stock offering that closed in
January 2004, the Company has significantly strengthened its balance
sheet by generating gross proceeds over the past eight months of more
than $39 million."

    Financial Results

    In the fourth quarter of 2003, OXiGENE narrowed its net loss to
$1.7 million, or $0.12 per share, from a net loss of $2.4 million, or
$0.19 per share, in the comparable period one year earlier. Included
in the financial results for the fourth quarter of 2003 is a one-time
$635,000 gain related to the liquidation of OXiGENE AB, the Company's
Sweden-based subsidiary, and stock-based compensation expense of
$95,000. Included in the financial results for the fourth quarter of
2002 is stock-based compensation expense of $523,000.
    For the 12-month period ended December 31, 2003, the Company
reported a net loss of $8.4 million, or $0.63 per share. This compares
with a net loss of $11.0 million, or $0.88 per share, in the 12-month
period ended December 31, 2002. Included in the net loss for full-year
2003 are $620,000 in stock-based compensation expense, $945,000 in
one-time charges related to the relocation of the Company's former
office in Watertown, Massachusetts, and a $635,000 gain related to the
liquidation of the Company's Sweden-based subsidiary. Included in the
net loss for the same period in 2002 is $2,940,000 in stock-based
compensation expense and a gain of $1,325,000 related to the sale of
the Company's joint venture with ARCUS Therapeutics.

    --  OXiGENE ended the fourth quarter of 2003 with approximately
        $18.9 million in cash and marketable securities and restricted
        cash. In addition, the Company raised gross proceeds of $24.2
        million in a Common Stock offering completed in January 2004.
        The Company currently has in excess of $40 million of cash,
        marketable securities and restricted cash.

    Significant Accomplishments in 2003

    --  New Cancer Trials. During the year, CA4P entered four Phase
        I/II human cancer trials in combination with a number of
        established treatment regimens. In Europe, the compound moved
        into the following studies: a clinical trial in combination
        with radiotherapy in patients with advanced carcinoma of the
        lung, head & neck and prostate; a clinical trial in
        combination with the chemotherapy drugs carboplatin and
        paclitaxel in advanced ovarian cancer; and a clinical trial in
        combination with a monoclonal antibody in advanced colorectal
        cancer. In the United States, the Ireland Cancer Center at
        University Hospitals of Cleveland (Ohio) began evaluating CA4P
        in combination with the chemotherapy drugs
        doxorubicin/cisplatin and radiation for the treatment of
        patients with newly diagnosed anaplastic thyroid cancer.

    --  First VTA Tested in Ophthalmology. The Johns Hopkins
        University School of Medicine began a Phase I/II study of CA4P
        in patients with wet age-related macular degeneration (AMD),
        the cause of severe vision loss in between two million and
        three million Americans. This marks the first time a vascular
        targeting agent has ever been evaluated in a
        non-life-threatening disease where current treatments are
        inadequate.

    --  Expansion of Ophthalmology Program. In December 2003, OXiGENE
        announced that the vision of a patient with a subfoveal
        neovascular disease known as myopic macular degeneration
        improved significantly after treatment with CA4P. Based on
        pre-clinical data of CA4P in ophthalmology, the Phase I/II
        trial in wet AMD and the response of this patient, the Company
        announced plans to broaden its research and development
        initiatives in ophthalmology. As part of that effort, in 2004
        the Company expects to launch a clinical study in myopic
        macular degeneration.

    --  Fast Track Status. The U.S. Food and Drug Administration (FDA)
        granted fast-track status to CA4P for the treatment of
        advanced anaplastic thyroid cancer, the rarest and deadliest
        form of the disease. The FDA's fast track program is designed
        to facilitate the development and expedite the review of new
        drugs intended to treat life-threatening conditions for which
        there is no approved therapy.

    --  Orphan Drug Designation. The FDA awarded the orphan drug
        designation to CA4P for the treatment of anaplastic,
        medullary, Stage IV papillary and Stage IV follicular thyroid
        cancers. Orphan drug designations are granted to provide
        economic incentives to stimulate the research, development and
        approval of promising products that treat rare diseases. The
        Orphan Drug Act guarantees seven years of market exclusivity
        in the United States to the first sponsor that obtains market
        approval for an orphan drug-designated product.

    --  Strengthened Balance Sheet. OXiGENE substantially improved its
        cash position in 2003 with a private placement of Common Stock
        that generated $15 million of gross proceeds to the Company.
        Last month, OXiGENE raised an additional $24.2 million in
        gross proceeds from the sale of approximately 2.8 million
        shares of Common Stock. With this recent infusion of cash, the
        Company currently has in excess of $40 million of cash,
        marketable securities and restricted cash.

    "From virtually every perspective, we are a vastly stronger
company than we were one year ago," Driscoll said. "During the year,
we took significant steps to advance our pre-clinical and clinical
development. This progress validated our expectations for the
technology and, in turn, allowed us to raise the necessary financial
resources to execute our strategy. We are now in a position of
strength as we continue to advance our clinical pipeline, with the
flexibility to be both opportunistic and measured in exploring
strategic alliances that can further enhance value for our
shareholders."

    Goals for 2004

    "During the past year, we have made outstanding progress in
expanding the clinical opportunities for our lead vascular targeting
compound in cancer and ophthalmology, and our goal is to sustain that
momentum in 2004," Driscoll said. OXiGENE's goals for the year
include:

    --  Accelerating enrollment in current trials by opening
        additional research sites

    --  Expanding certain existing trial protocols to include
        randomized, dual-arm studies

    --  Filing Investigational New Drug Applications (INDs) to begin
        CA4P clinical trials in new cancer indications

    --  Completing pre-clinical toxicology testing of Oxi4503 by
        Cancer Research UK and the initiation of a clinical study in
        the second half of 2004

    --  Filing an IND to initiate a clinical study in a disease
        involving subfoveal neovascularization

    --  Adding key personnel to accommodate the Company's aggressive
        clinical program

    --  Continuing partnership discussions
