                                    PART I

     Item 1.  Business

     General

        Cytogen Corporation ("Cytogen" or the "Company") is a biopharmaceutical
     company engaged in the discovery, development and marketing of products to
     better diagnose and treat disease.  Cytogen's current portfolio of products
     provides targeted delivery of diagnostic and therapeutic substances
     directly to the sites of disease.  Cytogen is using its patented and
     proprietary technologies to develop specific in vivo cancer diagnostic
     imaging and therapeutic products to build a focused cancer care franchise.
     Cytogen may expand from cancer into other therapeutic areas employing
     related technologies.

        Currently, Cytogen's highest priority products are: (i) OncoScint/(R)/
     CR/OV, the Company's monoclonal antibody-based diagnostic imaging agent for
     colorectal and ovarian cancer (see "OncoScint CR/OV"), which has been
     approved by the U.S. Food and Drug Administration ("FDA") since December
     1992 and, in its colorectal cancer application, in various European
     countries since June 1991; (ii) Samarium 153 EDTMP ("Samarium EDTMP"), a
     cancer therapy agent for the treatment of bone pain associated with bone
     metastases, which is in late Phase III clinical development with a New Drug
     Application ("NDA") submission to FDA anticipated in the first half of
     1995; and (iii) ProstaScint, a prostate cancer diagnostic imaging product,
     for which a Product License Application ("PLA") was submitted to FDA in
     January 1995.  Cytogen has licensed to The DuPont Merck Pharmaceutical
     Company ("DuPont Merck") the manufacturing and co-marketing rights to
     Samarium EDTMP in the U.S.  See "Marketing and Sales -- Samarium EDTMP --
     DuPont Merck".

        The Company is continuing to evaluate, invest in and support the sales
     and marketing activities with respect to OncoScint CR/OV.  While the
     product has technically performed as predicted in clinical applications,
     OncoScint CR/OV has achieved very limited sales, and negligible sales
     growth, in both the U.S. and European markets since its introduction.  The
     Company has also assigned high priority to the product development and
     commercialization programs for Samarium EDTMP and ProstaScint.

        The Company's strategic plan also supports continued commitment to its
     antibody "linker" technology through ongoing product development efforts
     for cancer therapeutic agents.  Cytogen expects to expand its current
     product portfolio through in-licensing products and technologies.  In
     addition, Cytogen has committed additional resources to its molecular
     recognition unit program which, as a result of recent patent filings and
     development trends, has been renamed the Totally Synthetic Affinity
     Reagents\SynGenes ("TSARs\SynGenes") program.  This program involves long
     peptides that have the ability to recognize and bind to specific target
     sites in the human body.  Cytogen believes that the ability of these
     compounds to bind to predetermined sites may mediate certain diagnostic or
     therapeutic effects more effectively than its current monoclonal antibody
     delivery systems and other existing products.  See "Research and
     Development -- TSARs\SynGenes".

     Cancer Diagnostic Imaging Products

        Overview.  The cancer diagnostic imaging products consist of Cytogen's
     monoclonal antibody-based imaging agents for colorectal, ovarian, prostate,
     bladder, breast and non-small cell lung cancers.

                                      -3-

 
        As a result of the Company's decision to focus on its more advanced
     products, studies for the bladder, breast and non-small cell lung cancer
     imaging agents were suspended in 1993.  The Company's imaging products for
     colorectal, ovarian, and prostate cancer utilize Cytogen's proprietary
     targeted delivery system, employing whole antibodies, to deliver the
     diagnostic radioisotope indium-111 to malignant tumor sites.

        During an imaging procedure, the radiolabeled monoclonal antibody
     product is injected into the patient.  The antibody travels through the
     body seeking out and binding to tumor sites.  The radioactivity from the
     isotope that has been attached to the antibody can be detected from outside
     the body by a gamma camera.  The resultant image identifies the existence,
     location and extent of disease in the body.  Based on clinical studies
     conducted to date by physicians on behalf of Cytogen, the imaging agents
     have the potential to provide new and useful information not available from
     other diagnostic modalities regarding the existence, location and extent of
     the disease (and particularly occult disease not detected by other methods)
     throughout the body.  Cytogen believes that this information has the
     potential to impact the way physicians manage their patients' individual
     treatments.  Cytogen also believes that, because its products use a very
     low dose of one milligram or less of antibody conjugate per administration,
     the products have the additional advantages of low manufacturing cost and
     ease of administration.  The imaging products are supplied to hospitals and
     central radiopharmacies without the radioisotope.  Prior to patient
     administration, the radioisotope is attached by the radiopharmacist using a
     simple liquid transfer procedure developed by Cytogen.

        OncoScint CR/OV.  OncoScint CR/OV was approved by FDA in the U.S. in
     December 1992.  This product was approved for single use with other
     appropriate diagnostic tests to locate malignancies outside the liver in
     patients with known colorectal or ovarian cancer.  Prior to receipt of FDA
     approval, Cytogen had completed additional clinical trials which support
     repeat administration of the product, and submitted that data to FDA.  To
     date, FDA has not issued an approval or non-approval letter for this
     expanded indication.

        With respect to Europe, this data was also submitted to the Committee
     for Proprietary Medicinal Products (the "CPMP").  In December 1993,
     OncoScint CR/OV received CPMP approval for repeat administration and
     ovarian cancer indications.  Individual member country approvals must be
     obtained before marketing under these new indications can be commenced.
     OncoScint CR/OV in its colorectal single-dose application has been approved
     for sale in eight Western European countries, including Germany, Italy, the
     United Kingdom and France.

        Currently, OncoScint CR/OV is being marketed in the U.S. by Cytogen.
     Cytogen reacquired the U.S. marketing rights ("U.S. Rights") for the
     product from Knoll Pharmaceutical Company ("Knoll") in November 1994.  See
     "Marketing and Sales -- Knoll Pharmaceutical".  Cytogen also reacquired the
     European marketing rights for OncoScint CR/OV from Chiron B.V., formerly
     EuroCetus B.V., successor in interest to EuroCetus International, N.V.
     ("Chiron") in February 1995.  See "Marketing and Sales --Chiron B.V.".

        Because Cytogen is the first sponsor to obtain FDA marketing approval
     for a monoclonal antibody-based ovarian cancer imaging product that has
     been designated as an orphan drug by FDA, Cytogen is entitled to certain
     exclusive marketing rights with respect to the product.  See "Government
     Regulation and Product Testing--Orphan Drug Act."

        ProstaScint.  ProstaScint is a monoclonal antibody that is being
     developed as a radiolabeled imaging agent to detect the presence and extent
     of prostate cancer.  The product has been studied in three different
     indications: presurgical, occult and repeat administration.  The Phase III
     clinical program for

                                      -4-

 
     ProstaScint has been completed and the PLA was submitted to FDA in January
     1995.  Cytogen is pursuing a co-marketing partner for ProstaScint in the
     U.S. and is also seeking international marketing alliances for the product.

     Cancer Therapeutic Products

        Samarium EDTMP.  Samarium EDTMP is being developed as a treatment for
     the pain associated with bone metastases, a condition that occurs when
     cancer originates in or spreads to the bone.  The first of two Phase III
     studies for Samarium EDTMP, involving 117 patients, has been completed and
     is currently being analyzed.  The second Phase III study has enrolled over
     100 patients thus far and is near completion.  Based on a pre-NDA meeting
     with FDA held in November 1994 and subsequent discussions with
     representatives from the agency, Cytogen expects to file its NDA with
     respect to this product in the first half of 1995.

        Cytogen entered into an exclusive license agreement for the U.S. rights
     to Samarium EDTMP from The Dow Chemical Company in March 1993 and assumed
     responsibility for the development and commercialization of the product at
     that time.  See Note 5 to the Consolidated Financial Statements.  In
     December 1994, Cytogen granted to DuPont Merck a license with respect to
     Cytogen's rights to Samarium EDTMP.  See "Marketing and Sales -- Samarium
     EDTMP".

        Antibody-Based Cancer Therapeutics.  Cytogen continues to develop
     antibody-based, cancer therapeutics.  These products utilize technology
     similar to the Company's diagnostic products.  However, in therapeutic
     products the substance linked to the antibody is a radioisotope that
     destroys tumor cells.

        The therapeutic radioisotope, yttrium-90, is chemically attached to the
     monoclonal antibodies using Cytogen's proprietary technology.  It is
     intended that the therapy products will be supplied to radiopharmacies
     without the radioisotope, which will be attached by the radiopharmacist
     using a simple procedure developed by Cytogen.  The prostate therapy
     product is in Phase I clinical trials.  The ovarian therapy product has
     completed Phase II clinical trials.  Further development of this product is
     currently under evaluation.  Studies for the bladder therapy product were
     suspended in 1993 because test results had not met the expectations of
     Cytogen and CytoRad (defined below).

     Research and Development

        TSARs\SynGenes.  Long-term research, much of which is preliminary, is
     being conducted by the Company on TSARs\SynGenes.  The TSARs\SynGenes
     program consists of research on long peptides, which may be derived from
     random peptide libraries, and long-term projects related to the discovery
     of synthetic genes, called SynGenes.  Cytogen believes its TSARs\SynGenes
     technology may represent a significant advance over monoclonal antibody
     delivery systems for certain applications.  Cytogen is working,
     independently and in collaboration with others, to develop this technology
     into a new generation of product applications.  TSARs\SynGenes have several
     characteristics that represent potential advantages over whole antibody-
     based products.  With molecular weights of as low as 2,000 daltons, as
     opposed to 150,000 daltons for a whole monoclonal antibody, TSARs\SynGenes
     will travel quickly through the body and may reach more sites due to their
     small size than could whole antibodies.  TSARs\SynGenes can be chemically
     synthesized, making their production simpler and less expensive than the
     production of monoclonal antibodies, which are biologically produced and
     then chemically modified.  Another significant potential advantage of
     TSARs\SynGenes may be that they are not expected to generate an immunologic
     response (i.e., the body's immune system will not produce antibodies in
     response to the introduction of TSARs\SynGenes, which could impair repeated
     use of the product).  Cytogen is the exclusive licensee of certain patent
     applications and technology held by the University of North Carolina

                                      -5-

 
     at Chapel Hill covering TSARs technology.  Cytogen has filed patent
     applications in the U.S. and certain foreign countries with respect to the
     TSARs\SynGenes technology.

        While a significant amount of basic research on TSARs\Syngenes
     technology has been done by Cytogen, this technology is at an earlier stage
     of development than the technology underlying the monoclonal antibody-based
     products described above.  Research on TSARs\SynGenes to date has focused
     on (i) product development in the oncology area in conjunction with
     Cytogen's future product development programs and (ii) additional areas of
     basic research which, if successful, may become the foundation for products
     outside of oncology and for out-licensing opportunities based on this
     technology.

        PSM.  In 1993, Cytogen and Memorial Sloan-Kettering Cancer Center
     ("MSKCC") began a development program involving the prostate specific
     membrane antigen ("PSM") and Cytogen's prostate cancer monoclonal antibody
     conjugate, CYT-356.  Work conducted by MSKCC has demonstrated that assays
     looking for mRNA encoding PSM have the potential to detect circulating
     cancer cells in the blood of patients at a higher rate than the well-known
     and widely used screening techniques that utilize the prostate specific
     antigen.  This finding has the potential to be developed as a general blood
     screening assay for prostate cancer.  Cytogen and MSKCC are pursuing this
     development program.  Cytogen holds an exclusive option for an exclusive
     license under certain patent applications and technology held by MSKCC
     relating to PSM.  Additionally, Cytogen is actively seeking license and
     development agreements to support the PSM program.  However, no assurances
     can be given regarding the success or timing of these efforts.

        Humanized Monoclonal Antibodies.  Most of the monoclonal antibodies
     currently used in developmental biotechnology products, including
     Cytogen's, are derived from mice.  While the results of Cytogen's research
     to date indicate that immune response has not presented a safety question,
     it is possible that the effectiveness of these products in some patients,
     particularly in multiple-use applications, may be adversely affected by an
     immunological response known as Human Anti-Mouse Antibody ("HAMA").  One
     possible means of reducing the HAMA response is to graft the antigen
     binding regions of a murine, or mouse, antibody into a human antibody
     thereby creating a "humanized" monoclonal antibody.  Cytogen is conducting
     and/or sponsoring research to develop humanized antibodies that Cytogen
     believes may improve the efficacy of its therapeutic products.

        Other Applications.  Cytogen believes that certain of the technologies
     it is developing may have medical applications in various other areas,
     including autoimmune disorders and infectious diseases.  Cytogen intends to
     expand the research and development of these technologies primarily through
     strategic alliances with other entities.  Cytogen expects to devote
     resources to these other areas to the extent funding is available.  No
     prediction can be made, however, as to when or whether the areas of
     research described above will yield new scientific discoveries, or whether
     such research will lead to new commercial products.

     Research and Development Funding

        Research and development expenditures recorded by Cytogen reflect
     projects conducted by the Company and payments made to sponsored research
     programs and consultants.  Cytogen's expenses for its research and
     development activities (including customer sponsored programs) were $20.3
     million, $24.8 million and $21.7 in fiscal years 1994, 1993 and 1992,
     respectively.  These expenses principally reflect product development
     efforts and support for various ongoing clinical trials.  Research and
     development expenditures for customer sponsored programs, including
     CytoRad, were $29,000, $9,112,000, and $8,868,000 in fiscal years 1994,
     1993 and 1992, respectively.

                                      -6-

 
     Marketing and Sales

        OncoScint.  Promotion of OncoScint CR/OV is targeted to hospital-based
     physicians, including those who refer patients for imaging procedures and
     those who obtain and interpret the image.  Referring physicians are likely
     to be surgeons and oncologists.  Imaging physicians are nuclear medicine
     specialists and those diagnostic radiologists who have subspecialty
     training in nuclear medicine.  After receipt of FDA approval in May 1993 of
     Cytogen's marketing materials for OncoScint CR/OV, Cytogen began its
     marketing in the U.S. through its own specialty sales force  with an
     expertise in nuclear medicine, and through a co-promotion arrangement with
     Knoll, which agreement was terminated in 1994.  See "Knoll Pharmaceutical".
     Since May 20, 1994, Cytogen has been the sole marketer of OncoScint CR/OV
     in the U.S.  In 1989, Chiron was granted exclusive marketing and
     distribution rights in Europe for OncoScint CR/OV, which rights were
     reacquired in 1995 by the Company under the terms of a disengagement
     agreement (the "Disengagement Agreement").  See "Chiron B.V."

        OncoScint CR/OV is a very technical product that requires a high degree
     of proficiency in nuclear imaging, as well as a thorough appreciation of
     the information the scan can provide.  The Company believes that this
     information regarding the actual existence, location and extent of disease
     has the potential to impact a physician's ability to make effective and
     efficient patient management decisions.

        Cytogen believes that sales of OncoScint CR/OV may be increased through
     approval of repeat administration, which is currently pending with FDA,
     implementation of better quality control at the time the image is actually
     acquired and through greater assistance with the interpretation of the
     scans.  The Company is exploring advances in teleradiology in order to
     improve the acquisition and interpretation of an OncoScint CR/OV scan.  In
     its strictest form, teleradiology provides real-time, two-way audio and
     video communications by linking a radiology center with an off-site
     radiology specialist.  The use of teleradiology has advanced due to
     improvements in related computer and telecommunication technologies.


        Knoll Pharmaceutical.  On November 1, 1994, Cytogen executed a
     termination agreement (the "Termination Agreement") with Knoll.  Pursuant
     to the Termination Agreement, Cytogen has reacquired from Knoll all U.S.
     Rights to OncoScint CR/OV, which were previously granted to Knoll pursuant
     to a License, Supply and Marketing Agreement dated December 19, 1991 (the
     "Knoll Agreement").  The Termination Agreement requires Cytogen to pay to
     Knoll $3.0 million, without interest, over a four-year period, to reacquire
     the U.S. Rights and reschedules the payment of approximately $5.0 million
     of liabilities previously incurred under the terms of the Knoll Agreement.
     Under the terms of an Order Fulfillment Agreement effective November 1,
     1994, Knoll will continue to provide warehousing, shipping, invoicing and
     collection services to Cytogen until June 30, 1995.

        Under the terms of the Knoll Agreement, in fiscal years 1994 and 1993,
     the Company incurred $412,000 and $5.1 million, respectively, in co-
     promotion expenses, and recognized $430,000 and $977,000 in co-promotion
     revenues.  In fiscal year 1992, the Company recorded a milestone payment
     from Knoll.  In each of those fiscal years, the Company also recognized
     revenues from the supply of commercial product to Knoll by the Company.
     See Note 4 to the Consolidated Financial Statements.

        Chiron B.V.  On December 30, 1994, Cytogen entered into the
     Disengagement Agreement with Chiron.  Pursuant to a Distribution and
     License Agreement dated as of October 21, 1989, as amended, Cytogen granted
     to Chiron exclusive marketing and distribution rights in Europe (the
     "European Rights") to OncoScint CR/OV.  Under the Disengagement Agreement,
     Cytogen reacquired the European Rights and purchased certain business
     assets relating to the European Rights, including existing approvals by the
     appropriate regulatory authorities to market OncoScint CR/OV in twelve
     countries in Europe.  This

                                      -7-

 
     reacquisition was consummated on February 16, 1995.  The reacquisition
     price is $1 million, payable over three years, without interest, and
     payment of the reacquisition price is secured by a mortgage covering
     approximately 11 acres of undeveloped real property owned by Cytogen in
     Ewing, New Jersey.  This obligation is non-recourse to Cytogen.  Until the
     earlier of (i) an agreement with a new European distributor, or (ii)
     December 31, 1995, Chiron will continue to provide warehousing and European
     distribution services to Cytogen.  Cytogen recognized contract and product
     related revenue from Chiron of $162,000, $164,000 and $377,000 in the
     fiscal years 1994, 1993 and 1992, respectively.  See Note 9 to the
     Consolidated Financial Statements.

        In the U.S., Cytogen is considering maintaining its direct selling
     efforts, as well as co-promotion arrangements or licensing of all rights to
     a third party.  Cytogen intends to secure alternative marketing and
     distribution partners for OncoScint CR/OV in Europe and Japan.


     Samarium EDTMP

        DuPont Merck.  On December 20, 1994, Cytogen entered into a license
     agreement (the "DP/Merck Agreement") with DuPont Merck.  Under the terms of
     the DP/Merck Agreement, Cytogen granted to DuPont Merck a license with
     respect to Cytogen's rights to Samarium EDTMP pursuant to which DuPont
     Merck will have responsibility for manufacturing and co-marketing Samarium
     EDTMP in the U.S., if and when approved for marketing by FDA.  See "Cancer
     Therapeutic Products -- Samarium EDTMP".

        The DP/Merck Agreement provides that Cytogen will receive from DuPont
     Merck up-front fees and milestone payments consisting of:  (i)$1.0 million
     upon execution of the DP/Merck Agreement, which has been paid to Cytogen;
     (ii) $4.0 million from the sale to DuPont Merck of 908,265 shares of
     Cytogen common stock within 20 days of the execution of the DP/Merck
     Agreement, which sale has occurred, (iii) $4.25 million to fund additional
     clinical programs to expand the use and marketing of Samarium EDTMP, of
     which $1,334,000 was received in January 1995, (iv) a $2.0 million
     milestone payment if and when Samarium EDTMP receives FDA approval and (v)
     royalty payments based on sales, including guaranteed minimum payments.


     Relationship and Subsequent Merger with CytoRad

        CytoRad Incorporated ("CytoRad"), a biopharmaceutical company formed in
     December 1991, was established to engage in the research and development of
     proprietary antibody-based delivery systems for the diagnosis and/or
     treatment of prostate, ovarian and bladder cancers, utilizing technology
     licensed from Cytogen.  In February 1992, Cytogen and CytoRad commenced a
     public offering of 4,025,000 CytoRad units, each unit consisting of one
     share of callable common stock of CytoRad and one warrant to purchase one
     share of Cytogen common stock at $24.15 per share.  All of the net proceeds
     of the offering were paid to CytoRad.  In connection with the public
     offering, Cytogen and CytoRad entered into a series of contractual
     arrangements.  Subject to the terms and conditions of the agreements
     between Cytogen and CytoRad, CytoRad was required to make up-front and
     periodic payments to Cytogen, and in return Cytogen conducted research and
     development on behalf of CytoRad relating to the products licensed pursuant
     to agreements.  As a result of the agreements, Cytogen recorded $5,903,000
     and $6,064,000 of contract revenues in fiscal years 1993 and 1992,
     respectively, in addition to $2.0 million and $3.0 million in up-front
     license fees received from CytoRad in fiscal years 1993 and 1992,
     respectively.

                                      -8-

 
        In March 1994, CytoRad announced that it was exploring modifications to
     its then existing business relationship with Cytogen.  Accordingly, the
     CytoRad Board of Directors did not approve the 1994 development agreement
     budget and subsequently, no contract revenues from CytoRad were recorded by
     Cytogen in fiscal year 1994.  During fiscal years 1993 and 1992, funds
     provided under those agreements represented the principal source of funding
     for the development of the products involved.  See Note 3 to the
     Consolidated Financial Statements.

        On July 29, 1994, Cytogen and CytoRad jointly announced that they had
     reached an agreement in principle relating to the acquisition of CytoRad by
     Cytogen, and on November 15, 1994, the parties announced that they had
     signed a definitive agreement relating thereto.  Pursuant to the merger
     agreement, Cytogen offered to exchange for each CytoRad unit (a) 1.5 shares
     of Cytogen common stock, (b) a warrant to acquire one share of Cytogen
     common stock for $8.00 that expires January 31, 1997 and (c) a contingent
     value right (a "CVR") to receive, under certain circumstances and at no
     additional cost, up to an additional one-half share of Cytogen common
     stock.

        On February 24, 1995, Cytogen announced that it had completed the
     exchange offer, pursuant to which approximately 93% of the outstanding
     CytoRad units were validly tendered.  On February 27, 1995, Cytogen
     announced that it had completed its acquisition of CytoRad by merging
     CytoRad with and into a wholly-owned subsidiary of Cytogen pursuant to the
     merger agreement.  Holders of CytoRad common stock who did not tender their
     CytoRad units in the exchange offer became entitled to receive as a result
     of the merger one and one-half shares of Cytogen common stock and one CVR
     for each share of CytoRad common stock owned thereby.  Although the
     previously issued warrants forming a part of the CytoRad units not tendered
     in the exchange offer will remain outstanding following the merger, Cytogen
     has agreed that such warrants will be exercisable at $8.00 per warrant
     share pursuant to the merger agreement.

        The stockholders of Cytogen were required to approve the issuance of the
     Cytogen securities issuable in connection with the acquisition, which
     approval was obtained on February 23, 1995.  As a result of the
     acquisition, Cytogen reacquired the product rights to the prostate, ovarian
     and bladder products it had previously licensed to CytoRad.  In addition,
     consummation of the merger resulted in the transfer of $11.7 million of
     CytoRad's cash and securities to the Company.  See Note 3 to the
     Consolidated Financial Statements.


     Limited Field of Use License Agreements

        In addition to development of its own proprietary products, Cytogen has
     entered into limited field of use licenses for rights in its proprietary
     technology with various pharmaceutical companies in the U.S. and Europe.
     Although the terms of each agreement differ, these agreements generally
     provide for royalty payments to Cytogen based on any future product sales.
     Some of these agreements also provide for fixed payments, purchases of
     Cytogen stock, milestone payments and payments for research services
     performed by Cytogen.

        Lilly.  In April 1989, Cytogen entered into limited field of use license
     agreements with Eli Lilly and Company ("Lilly") (collectively, the "Lilly
     Agreement") granting to Lilly a non-exclusive worldwide license to develop
     and market certain cancer therapy products using Cytogen's proprietary
     monoclonal antibody linker technology to deliver the vinca alkaloid class
     of compounds, and other cancer therapy drugs proprietary to Lilly.
     Pursuant to the terms of the Lilly Agreement, in addition to the cash
     payment and stock purchase already made, Lilly is required to make certain
     payments to Cytogen which in some cases are dependent upon Lilly's
     achievement of certain scientific milestones in its research.  The Lilly
     Agreement also provides for royalty payments (which are subject to
     abatement to a certain extent based

                                      -9-

 
     on milestone payments made) based on net sales of any resulting products.
     Under the Lilly Agreement, Cytogen is required to inform Lilly of
     improvements to Cytogen's technology and Lilly can terminate the Lilly
     Agreement at any time following the milestone payments described above upon
     60 days' prior notice.

        Bracco.  In September 1989, Cytogen entered into an agreement (the
     "Bracco Agreement") with Bracco Industria Chimica S.p.A. ("Bracco")
     granting Bracco an exclusive option to license magnetic resonance imaging
     enhancement agents using the Company's linking technology.  Cytogen
     recognized revenue from Bracco pursuant to the Bracco Agreement for
     research services equal to $41,000, $860,000 and $1,343,000 in fiscal years
     1994, 1993 and 1992, respectively.  Cytogen does not anticipate that it
     will receive any additional revenues under the Bracco Agreement.  See Note
     10 to the Consolidated Financial Statements.

        Sterling.  In April 1986, Cytogen entered into a limited field of use
     license agreement with Eastman Kodak Company ("Kodak"), the rights and
     obligations of which were subsequently assigned by Kodak to its subsidiary,
     Sterling Drug Inc. ("Sterling"), under an amended and restated agreement
     with Sterling in April 1989 (the "Sterling Agreement").  Cytogen terminated
     the research arrangements under the Sterling Agreement in July 1992.
     Cytogen also has given Sterling notice terminating the Sterling Agreement
     and the parties are currently negotiating the terms and conditions of such
     a termination.  Cytogen recognized revenues under the Sterling Agreement
     from sales of research services of $583,000 in fiscal year 1992.

        Other Agreements.  Cytogen also has limited field of use license
     agreements with American Cyanamid Company and Farmitalia Carlo Erba S.r.l.
     ("FICE").  The American Cyanamid agreement relates to development,
     manufacture and sale of products utilizing Cytogen's proprietary monoclonal
     antibody-based delivery system to deliver to tumor sites certain
     chemotherapeutics such as methotrexate, and certain other compounds, some
     of which are proprietary to American Cyanamid.  Cytogen does not anticipate
     receiving payments under the Cyanamid agreement in the near future.
     Cytogen's limited field of use license agreement with FICE relates to
     manufacture and marketing of monoclonal antibody-based anthracycline
     chemotherapeutic products.  At the present time the parties to the FICE
     agreement are discussing its termination.  In addition, Cytogen also has
     entered into license agreements pursuant to which Cytogen sponsors certain
     research programs for the development of certain antibodies, antibody
     fragments, antigens and other protein products.

     Manufacturing

        Cytogen has established limited commercial-scale manufacturing capacity
     in Princeton, New Jersey.  An Establishment License Application ("ELA") for
     the facility in Princeton utilized by Cytogen for production of OncoScint
     CR/OV was approved by FDA in December 1992.  It is expected that this
     facility will allow Cytogen to meet its projected production requirements
     for the OncoScint product line in both the U.S. and Europe for the near
     term, although no assurances can be given to that effect.  In 1993 and
     1994, Cytogen received additional regulatory approval from FDA for the
     expansion of its commercial manufacturing processes and facilities.
     Cytogen will be required to obtain regulatory approval for all of its
     commercial manufacturing processes and facilities.

        In 1994, Cytogen's manufacturing facility was expanded to provide
     processes and facilities for the manufacture of commercial quantities of
     the antibody used in ProstaScint.  An ELA Supplement was prepared in 1994
     in conjunction with the PLA for ProstaScint submitted to FDA in January
     1995.  After receipt of necessary regulatory approvals, Cytogen's facility
     will be the site for the commercial manufacture of ProstaScint.  It is
     expected that this facility will allow Cytogen to manufacture its

                                      -10-

 
     projected production requirements of ProstaScint for the near term,
     although no assurance can be given that the facility will receive the
     necessary regulatory approvals to produce commercial quantities of
     antibodies for ProstaScint, or that commercial quantities of antibodies
     will be otherwise obtained.


     Raw Materials

        The raw materials used in the manufacture of Cytogen's products include
     several different antibodies.  Cytogen has both exclusive and non-exclusive
     license agreements which permit the use of specific monoclonal antibodies
     in its products.  Cytogen's first product, OncoScint CR/OV, uses the same
     monoclonal antibody which has been supplied in clinical quantities and is
     being supplied in commercial quantities by a single contract manufacturer
     through a shared manufacturing agreement.  Cytogen anticipates that the
     supplier will be able to meet Cytogen's needs for commercial quantities of
     monoclonal antibody.  Cytogen currently has established a substantial
     inventory of monoclonal antibodies used in OncoScint CR/OV.  See
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations" and Note 1 to the Consolidated Financial Statements.

        Cytogen currently has the in-house production capacity necessary to
     produce projected commercial quantities of monoclonal antibody for
     manufacture of ProstaScint and clinical quantities of other monoclonal
     antibodies to develop other diagnostic imaging and therapy products.

     Human Resources

        As of December 31, 1994, Cytogen employed 137 persons full-time, of whom
     47 were engaged in research and development activities, 38 were engaged in
     operations and manufacturing, 29 were engaged in administration and
     management, and 23 were engaged in selling and marketing.  Of Cytogen's
     employees, 19 hold Ph.D. and/or M.D. degrees, and 17 hold other advanced
     degrees.  Cytogen, from time to time, hires scientific consultants to work
     on certain of its research and development programs.  Cytogen believes that
     it has been successful in attracting skilled and experienced scientific
     personnel; however, competition for such personnel is intense.

        None of Cytogen's employees is covered by a collective bargaining
     agreement.  All of Cytogen's employees have executed confidentiality
     agreements.  Cytogen considers relations with its employees to be
     excellent.

     Patents and Proprietary Rights

        Consistent with industry practice, Cytogen has a policy of using patent
     and trade secret protection to preserve its right to exploit the results of
     its research and development activities and, to the extent it may be
     necessary or advisable, to exclude others from appropriating Cytogen's
     proprietary technology.

        Cytogen's policy is to aggressively protect its proprietary technology
     by selectively seeking patent protection in a worldwide program.  In
     addition to the U.S., Cytogen files patent applications in Canada, major
     European countries, Japan and additional foreign countries on a selective
     basis to protect inventions important to the development of its business.
     Cytogen believes that the countries in which it has obtained and is seeking
     patent coverage for its proprietary technology represent the major focus of
     the pharmaceutical industry in which Cytogen and certain of its licensees
     will market its and their respective products.

                                      -11-

 
        Cytogen holds 13 current U.S. patents and 46 current foreign patents.
     Cytogen has filed and currently has pending ten U.S. patent applications
     and 20  foreign patent applications, covering certain aspects of its
     technology for diagnostic and therapeutic products, and the methods for
     their production and use.  Cytogen intends to file patent applications with
     respect to subsequent developments and improvements when it believes such
     protection is in the best interest of Cytogen.  Although the scope of
     patent protection which ultimately may be afforded by the patents and
     patent applications of Cytogen is difficult to quantify, Cytogen believes
     its patents will afford adequate protection to conduct its business
     operations as described in this Form 10-K.

        Cytogen's U.S. Patent No. 4,671,958, entitled "Antibody Conjugates For
     The Delivery of Compounds To Target Sites," is basic to many of Cytogen's
     current and proposed commercial operations.  This patent covers in vivo
     delivery methods using site-specific attachment of compounds to antibody
     molecules that maintain the antibody's ability to target and bind to
     antigens such as those expressed by or associated with tumors, blood clots,
     infections and other disease sites.  This patent is scheduled to expire in
     2004.  In Europe, similar protection is afforded by Cytogen's European
     Patent No. 0088695, entitled "Antibody Conjugates."

        Cytogen's U.S. Patent No. 4,741,900, entitled "Antibody Metal Ion
     Complexes," provides additional patent protection for its most advanced
     products which involve the targeting of radioisotopes to tumor cells for
     purposes of diagnosing or treating cancer.  This patent is scheduled to
     expire in 2004.  Cytogen's European Patent No. 0173629, entitled "Antibody
     Metal Ion Complexes" affords similar protection in Europe.

        Cytogen's U.S. Patent No. 4,867,973, entitled "Antibody-Therapeutic
     Agent Conjugates," provides broad patent protection for many of Cytogen's
     proposed commercial products and those of its licensees which are useful
     for the in vivo targeting of therapeutic agents for the treatment of a
     variety of cellular disorders.  This patent is scheduled to expire in 2004.

        Cytogen is the exclusive licensee of certain patent applications held by
     the University of North Carolina at Chapel Hill covering TSARs technology.
     Cytogen holds an exclusive option for an exclusive license under certain
     patent applications held by MSKCC covering PSM.  Cytogen is the exclusive
     licensee of certain U.S. patents and applications held by Dow covering
     Samarium EDTMP.

        Cytogen may be entitled under certain circumstances to seek extension of
     the terms of its patents.  See "Government Regulation and Product Testing--
     FDA Approval".

        Cytogen also relies upon, and intends to continue to rely upon, trade
     secrets, unpatented proprietary know-how and continuing technological
     innovation to develop and maintain its competitive position.  Cytogen
     typically enters into confidentiality agreements with its licensees and any
     scientific consultants, and Cytogen's employees have entered into
     agreements with Cytogen requiring that they forbear from disclosing
     confidential information of Cytogen, and assign to Cytogen all rights in
     any inventions made while in Cytogen's employ relating to Cytogen's
     activities.  Cytogen believes that its valuable proprietary information is
     protected to the fullest extent practicable; however, there can be no
     assurance that (i) any additional patents will be issued to Cytogen in any
     or all appropriate jurisdictions, (ii) litigation will not be commenced
     seeking to challenge Cytogen's patent protection or such challenges will
     not be successful, (iii) processes or products of Cytogen do not or will
     not infringe upon the patents of third parties, or (iv) the scope of
     patents issued to Cytogen will successfully prevent third parties from
     developing similar and competitive products.  It is not possible to predict
     how any patent litigation will affect Cytogen's efforts to develop,
     manufacture or market its products.

                                      -12-

 
        The technology applicable to Cytogen's products is developing rapidly.
     A substantial number of patents have been issued to biotechnology
     companies.  In addition, competitors have filed applications for, or have
     been issued, patents and may obtain additional patents and proprietary
     rights relating to products or processes competitive with those of Cytogen.
     In addition, others may have filed patent applications and may have been
     issued patents to products and to technologies potentially useful to
     Cytogen or necessary to commercialize its products or achieve its business
     goals.  There can be no assurance that Cytogen will be able to obtain
     licenses of such patents on terms acceptable to Cytogen.

        To the best of Cytogen's knowledge, there are no valid enforceable U.S.
     patents which it believes to be infringed by its present activities
     relating to its site-specific antibody linker technology or which would
     preclude the pursuit of its business activities as discussed in this Form
     10-K.  Cytogen has no knowledge which would rebut the statutory presumption
     of validity of its material U.S. patents identified above or which would
     preclude the enforceability of such patents, or of any materially relevant
     prior art references not cited in the U.S. Patent and Trademark Office.

        OncoScint is a registered trademark of Cytogen.  ProstaScint is a
     trademark of Cytogen, pending registration.

     Government Regulation and Product Testing

        The development, manufacture and sale of medical products utilizing
     Cytogen's technology are governed by a variety of statutes and regulations
     in the U.S. and by comparable laws and agency regulations in most foreign
     countries.

        FDA Approval.  The major regulatory impact on the diagnostic and
     therapeutic products in the U.S. derives from the Federal Food, Drug and
     Cosmetic Act (the "FD&C Act") and the Public Health Service Act, and from
     FDA rules and regulations promulgated thereunder.  These acts and
     regulations require carefully controlled research and testing of products,
     government review and/or approval prior to marketing the products,
     inspection and/or licensing of manufacturing and production facilities,
     adherence to good manufacturing practices during production and continued
     compliance with product specifications, labeling, and other post-production
     regulations.

        The medical products to which Cytogen intends to apply its technology
     are subject to substantial governmental regulation and may be classified as
     new drugs or biologics under the FD&C Act.  FDA and similar health
     authorities in most other countries must approve or license the diagnostic
     and therapeutic products before they can be commercially marketed.  In
     order to obtain FDA approval, an applicant must submit, as relevant for the
     particular product, proof of safety, purity, potency and efficacy.  In most
     cases such proof entails extensive pre-clinical, clinical and laboratory
     tests.  The testing, preparation of necessary applications and processing
     of those applications by FDA is expensive and time-consuming, and may take
     several years to complete.  Cytogen received FDA approval in December 1992
     to market OncoScint CR/OV in the U.S., together with approval of its ELA
     with respect to its manufacturing facility in New Jersey.  Although Cytogen
     believes its future applications will be approved, there is no assurance
     FDA will act favorably or quickly in making such reviews and approving
     products for sale.  Difficulties or unanticipated costs may be encountered
     by Cytogen or its licensees in their respective efforts to secure necessary
     governmental approval or licenses, which could delay or preclude Cytogen or
     its licensees from marketing their products.  Limited indications for use
     or other conditions could also be placed on any such approvals that could
     restrict the commercial applications of such products.  With respect to
     patented products or technologies, delays imposed by the government
     approval process may materially reduce the period during which Cytogen will
     have the exclusive right to exploit them, because patent protection lasts
     only for a limited time, beginning on the date the patent is first granted
     in the case of U.S. patent

                                      -13-

 
     applications and when the patent application is first filed in the case of
     patent applications filed in the European Economic Community.  Cytogen
     intends to seek to maximize the useful life of its patents under the Patent
     Term Restoration Act of 1984 in the U.S. and similar laws if available in
     other countries.

        The majority of the diagnostic and therapeutic products will likely be
     classified as new drugs or biologics and will be subject to the conduct of
     in vitro tests, pre-clinical testing and a three-phase evaluation process
     in humans before any marketing application can be prepared.  In Phase I, a
     product is tested in a small number of patients primarily for safety at one
     or more dosages.  In Phase II, in addition to safety, the efficacy of the
     product against particular diseases is evaluated in a patient population
     generally somewhat larger than Phase I.  Clinical trials of certain
     diagnostic agents frequently combine Phase I and Phase II into a single
     Phase I/II study.  In Phase III, the product is evaluated in a larger
     patient population sufficient to generate data to support a claim of safety
     and efficacy within the meaning of the FD&C Act.  Authorization or
     clearance under the FD&C Act by FDA must be obtained prior to conducting
     clinical testing by the filing of an exemption for an Investigational New
     Drug which includes the results of in vitro tests and pre-clinical testing.
     A similar procedure under the FD&C Act applies to medical devices and
     diagnostic products.

        A PLA summarizes the results of clinical tests and other product testing
     and must be filed with an ELA for the licensing of the product
     manufacturing processes and facilities for biologics such as OncoScint
     CR/OV.  An NDA, which is similar to a PLA, may be required to be filed if
     the product is classified as a drug rather than a biologic.

        Prior to a PLA or NDA submission, FDA conducts a pre-PLA/NDA meeting.
     The use of pre-PLA/NDA meetings has increased due to the introduction of
     FDA User Fees and the increased commitment on the part of FDA to conduct
     timely reviews of filed applications.  The primary purpose of both the pre-
     PLA and pre-NDA meeting is for the sponsor and FDA to discuss the content
     and timing of the application and determine whether FDA agrees with the
     sponsor, based on its preliminary review of the application, that the
     application is sufficiently complete to be filed and/or to identify any
     areas that need further evaluation or discussion prior to the filing.

        A pre-PLA/NDA meeting has the potential to avoid an FDA issued "refuse-
     to-file" letter that states the application is "deficient on the face" and
     cannot be reviewed in its present form.  Based on FDA regulations, once an
     application is submitted to FDA, FDA has 60 days to determine whether or
     not the application is sufficiently complete to be filed.  If FDA believes
     the application is not complete, FDA issues a refuse-to-file letter to the
     sponsor.

        Continued compliance with all requirements of the FD&C Act and the
     conditions in an approved application, including but not limited to product
     specification, manufacturing process, labeling and promotional material,
     and record keeping and reporting requirements, is necessary for all
     products.  Failure to comply, or the occurrence of unanticipated adverse
     effects during commercial marketing, could lead to the need for product
     recall, or FDA-initiated action, which could delay further marketing until
     the products are brought into compliance.  Similar laws and regulations
     apply in most foreign countries where the diagnostic and therapeutic
     products are likely to be marketed.

        Upon certain circumstances defined in the FD&C Act, certain products may
     be sold and distributed, in limited quantities, prior to receipt of final
     FDA approval.  Cytogen believes that certain of its products may qualify
     for such treatment; however, there can be no assurance that FDA will allow
     such sales or distribution.

                                      -14-

 
        Orphan Drug Act.  The Orphan Drug Act is intended to provide incentives
     to manufacturers to develop and market drugs for rare diseases or
     conditions affecting fewer than 200,000 persons in the U.S. at the time of
     application for orphan drug designation.  A drug that receives orphan drug
     designation and is the first product to receive FDA marketing approval for
     a particular indication is entitled to orphan drug status, a seven-year
     exclusive marketing period in the U.S. for that indication.  OncoScint
     CR/OV, in its ovarian application, has been designated an orphan drug.
     Under the Orphan Drug Act, the FDA cannot approve any application by
     another party to market an identical product for treatment of an identical
     indication unless (i) such party has a license from the holder of orphan
     drug status, or (ii) the holder of orphan drug status is unable to assure
     an adequate supply of the drug.  However, a drug that is considered by FDA
     to be different from a particular orphan drug is not barred from sale in
     the U.S. during such seven-year exclusive marketing period even if it
     receives marketing approval for the same product claim.

        Other Regulations.  In addition to regulations enforced by FDA, Cytogen
     is also subject to regulation under the Occupational Safety and Health Act,
     the Environmental Protection Act, the Toxic Substances Control Act, the
     Resource Conservation and Recovery Act, Nuclear Regulatory Commission and
     other present and potential future federal, state or local regulations.

        Foreign Regulatory Approval.  Prior to marketing its products in Western
     Europe and certain other countries, Cytogen will be required to receive the
     favorable recommendation of the CPMP followed by the appropriate government
     agencies of the respective countries.  Substantial requirements, comparable
     in many respects to those imposed under the FD&C Act, will have to be met
     before commercial sale is permissible in most countries.  There can be no
     assurance, however, as to whether or when governmental approvals (other
     than those already obtained) will be obtained or as to the terms or scope
     of those approvals.

     Competition

        The biopharmaceutical field is expected to continue to undergo rapid and
     significant technological change as well as extensive consolidation.
     Potential competitors in the U.S. are numerous and include pharmaceutical,
     chemical, biotechnology and medical device companies, many of which have
     substantially greater capital resources, marketing experience, research and
     development staffs and facilities than Cytogen.  This competition can be
     expected to become more intense as commercial applications for
     biotechnology and pharmaceutical products increase.  Some of these
     companies may be better able than Cytogen to develop, refine and market
     products based on monoclonal antibody-based technology, or on other
     technologies applicable to the diagnosis and treatment of cancer such as CT
     scanning, magnetic resonance imaging, and chemotherapeutic products.
     Cytogen is aware that several companies are engaged in the development of
     technology and products for targeted radioisotopic and drug delivery.
     Cytogen understands that certain of these competitors are in the process of
     conducting human clinical trials or have filed applications for marketing
     approval by government agencies of certain products which will compete with
     Cytogen's diagnostic and therapeutic products.  Pursuant to its limited
     field of use license agreements, Cytogen has granted certain rights to its
     licensees to develop and market cancer therapy products which may compete
     directly with Cytogen's diagnostic and therapeutic products.  Cytogen will
     receive royalties from any sale of such licensed products and Cytogen
     believes the information which presently is publicly available is
     insufficient to enable it to definitively evaluate the likely success of
     these competing products.  Cytogen depends principally upon its patented
     antibody-based linker technology to compete with other firms engaged in
     commercial applications of antibody technology.  For this reason, Cytogen
     has focused on those applications where it believes its technology will
     offer significant advantages over other existing technologies and its
     patents offer the most protection.

     Item 2.  Properties

        The Company currently leases approximately 107,700 square feet of
     administrative, laboratory and manufacturing space in three locations in
     Princeton, New Jersey.  The lease for its 56,900 square foot laboratory and
     manufacturing facility will expire on February 28, 2003 and provides two 5-
     year renewal options.  The Company has sub-leased 8,715 square feet of the
     laboratory facility to another company.  This sub-lease will expire in
     April 30, 1996.  The lease for the Company's 31,400 square foot office
     space in Princeton, New Jersey will expire on June 15, 1997, subject to the
     Company's right to renew through June 15, 2002.  The Company also leases an
     additional 19,400 square feet at a third location in Princeton, New Jersey,
     under a lease which will expire in December 1999.  This third location is
     used for laboratories and support for production of commercial product.
     The Company expects to remain in the Princeton, New Jersey area for the
     foreseeable future.  As of December 31, 1994, the Company had invested
     approximately $9.0 million for improvements in the buildings it occupies.
     The Company leases some of the equipment used in its laboratory and
     manufacturing facility.  See Note 17 to Consolidated Financial Statements
     included in this Form 10-K for information regarding the Company's
     obligations under these real property and equipment leases.

        The Company believes its facilities are in good operating condition and
     that all real property and equipment are adequate for all present and
     proposed uses thereof.

     Item 3.  Legal Proceedings

        On September 17, 1992, a class action complaint was filed in the United
     States District Court for the District of New Jersey against the Company
     and three individual defendants, George W. Ebright, Thomas J. McKearn and
     Martin D. Cleary, alleging violations of Sections 10(b) and 20 of the
     Exchange Act and Rule 10b-5 promulgated thereunder.  At the time the
     complaint was filed, Messrs. Ebright, McKearn and Cleary served as officers
     of the Company and Messrs. Ebright and McKearn served as directors of the
     Company.  The complaint alleged that certain statements relating to the
     marketing and distribution in Europe of the Company's colorectal cancer
     imaging product were false and misleading, and sought damages in an
     unspecified amount.  The Company and the individual defendants denied any
     wrongdoing.

        On August 19, 1994, an Order was entered by Judge Hughes, United States
     District Court for the District of New Jersey, which preliminarily approved
     a settlement between the parties subject to a final hearing to determine
     whether the settlement was fair, reasonable and adequate.  At a hearing
     held on November 18, 1994, Judge Hughes gave final approval to the
     settlement, which provides for a $1,950,000 cash payment (which includes
     approximately $900,000 of fees and expenses of plaintiffs' counsel), the
     issuance of 197,942 shares of the Company's common stock and an additional
     $500,000 payable if the Company has annual earnings per share of $.50 or
     greater during any fiscal year commencing with 1993 through 1996.  The cost
     of the settlement was recorded as a liability at January 1, 1994.

     Item 7.  Management's Discussion and Analysis of Financial Condition and
     Results of Operations

          Beginning with 1994, the Company changed from a fiscal year end to a
     calendar year end.  Previously, the Company operated on a 52-53 week fiscal
     year ending on the Saturday nearest to December 31.  References below to
     1993 and 1992 relate to fiscal years ended January 1, 1994 and January 2,
     1993, respectively.

     Results of Operations

          Background.  Historically, the Company's revenues have resulted
     primarily from (i) payments received from the sale of research services
     pursuant to collaborative agreements, (ii) fees generated from the
     licensing of its technology and marketing rights to its products and (iii)
     product related revenues on sales of its OncoScint product since 1992 in
     Western Europe and since January 1993 in the U.S.  Beginning February 1992,
     the sales of research services by the Company included revenues from
     CytoRad for the development of certain cancer imaging and radiotherapy
     products licensed by the Company to CytoRad.  During 1994, because of a
     contractual dispute between the Company and CytoRad, no contract revenues
     were recorded by the Company for research services performed on behalf of
     CytoRad, although the Company continued with the development of the
     products licensed to CytoRad.  On November 15, 1994, the Company and
     CytoRad entered into an agreement for the acquisition of CytoRad by the
     Company.  On February 23, 1995, the Company's shareholders approved the
     issuance of the Company's securities necessary to effect the acquisition of
     CytoRad and on February 27, 1995, the Company completed its acquisition of
     CytoRad by merging CytoRad with and into a wholly-owned subsidiary of the
     Company.  As a result of the merger, the Company will not recognize any
     further contract revenues from CytoRad and $11.7 million of CytoRad's cash
     and securities were transferred to the Company.  In addition, the Company
     estimates that it will record in the first quarter of 1995 approximately
     $20 million for acquired research and development on its statement of
     operations, representing the amount by which the purchase price exceeds
     CytoRad's net book value.  This estimated charge to the statement of
     operations may change based upon the Company's final accounting for this
     transaction.

          On December 20, 1994, the Company entered into a license agreement
     with DuPont Merck pursuant to which DuPont Merck will have responsibility
     for manufacturing and co-marketing Samarium EDTMP in the U.S., if and when
     approved for marketing by FDA.  Pursuant to the DP/Merck Agreement, the
     Company received from DuPont Merck an up-front cash payment of $1,000,000
     in December 1994 and additional payments in 1995.  See Note 2 to the
     Consolidated Financial Statements.

          Beginning July 1, 1994, as a result of the change in the Company's
     relationship with Knoll, product related revenues have included product
     sales by the Company to its U.S. customers.  See Note 4 to the Consolidated
     Financial Statements.  Since that date, the Company has not recorded any
     product sales to Knoll or any co-promotion revenues.  In addition, on
     December 30, 1994, the Company entered into a Disengagement Agreement with
     Chiron to reacquire the exclusive marketing and distribution rights in
     Europe previously granted to Chiron.  This reacquisition was consummated on
     February 16, 1995.  See Note 9 to the Consolidated Financial Statements.

          Currently, the Company's focus is to provide the highest level of
     support for those products which are the most advanced.  The Company's
     highest priority products are: (i) OncoScint CR/OV; (ii) Samarium EDTMP,
     which is in late Phase III clinical development with an NDA submission to
     FDA anticipated in the first half of 1995; and (iii) ProstaScint, for which
     a PLA was submitted to FDA in January 1995.  The Company is continuing to
     evaluate, invest in and support the sales and marketing activities with
     respect to OncoScint CR/OV.  In addition, the Company has assigned high
     priority to the product development and commercialization programs for
     Samarium EDTMP and ProstaScint.  The Company's strategic plan also supports
     continued commitment to its antibody "linker" technology through

                                      -21-

 
     ongoing product development efforts for cancer therapeutic agents.  The
     Company expects to expand its current product portfolio through in-
     licensing products and technologies.  Finally, the Company has committed
     additional resources to its TSARs\SynGenes program.

          Revenues.  Total revenues were $2.5 million in 1994, $10.4 million in
     1993 and $13.4 million in 1992.  Product related revenues from sales of
     OncoScint CR/OV were $1.4 million in 1994 and included domestic sales of
     $1.2 million, Western European sales of $162,000 and a $109,000 reduction
     for returns of OncoScint CR/OV inventory because of shelf life expiration.
     In 1993, product related revenues were $1.6 million, including domestic
     sales of $1.4 million and Western European sales of $164,000.  In 1992,
     product related revenues from the sales of OncoScint Colorectal in Europe
     were $367,000.

          To date, sales of OncoScint CR/OV in both the U.S. and European
     markets have been limited, even though the product has technically
     performed as predicted in clinical applications.  OncoScint CR/OV is a very
     technical product that requires a high degree of proficiency in nuclear
     imaging, as well as a thorough appreciation of the information the scan can
     provide.  Cytogen believes that sales of OncoScint CR/OV may be increased
     through approval of repeat administration, which is currently pending with
     FDA, implementation of better quality control at the time the image is
     actually acquired and through greater assistance with the interpretation of
     the scans.  The Company is exploring advances in teleradiology in order to
     improve the acquisition and interpretation of an OncoScint CR/OV scan.

          In the past, the Company relied in large part on third parties to
     market its product.  In 1994, the Company decided to reacquire the
     marketing rights to OncoScint CR/OV from its U.S. and European
     distributors, Knoll and Chiron, respectively.  In anticipation of the
     execution of the Termination Agreement with Knoll, as of May 20, 1994,
     Knoll ceased its selling efforts and the Company resumed responsibility for
     the U.S. marketing of OncoScint CR/OV.  Beginning July 1, 1994, product
     related revenues included direct product sales of $854,000 by the Company
     to its U.S customers.  The Company is considering, with respect to the
     marketing of OncoScint CR/OV in the U.S., maintaining its direct selling
     efforts, as well as co-promotion arrangements or licensing of all rights to
     a third party.  The Company intends to secure alternative marketing and
     distribution partners for OncoScint CR/OV in Europe and Japan.  There can
     be no assurances that these efforts will be successful or that product
     related revenues will increase markedly.

          License and contract revenues for 1994, 1993 and 1992 included
     milestone payments of $1.0 million, $2.0 million, and $5.0 million,
     respectively.  In 1994, the Company received a $1.0 million milestone
     payment from DuPont Merck upon its entering into an agreement with the
     Company to manufacture and co-market Samarium EDTMP in the U.S.  See Note 2
     to the Consolidated Financial Statements.  In 1993, the Company received a
     milestone payment of $2.0 million from CytoRad as a one-time licensing fee
     for rights to the Company's ovarian cancer radiotherapy product and related
     technology.  In 1992, the Company received $3.0 million from CytoRad as a
     one-time licensing fee for rights to prostate and bladder products
     utilizing the Company's technology and $2.0 million from Knoll upon the
     Company's receipt of FDA marketing approval for OncoScint CR/OV.  Revenues
     from the sale of research services were $47,000 in 1994 compared to $6.8
     million in 1993 and $8.0 million in 1992.  The decrease in 1994 is
     attributable primarily to the absence of contract revenues from CytoRad.
     Due to the uncertainty of the CytoRad business relationship, the Company
     did not recognize any contract revenues for research services performed on
     behalf of CytoRad.  In 1994, the Company recorded an aggregate of $47,000
     of contract revenues from Bracco and Chiron.  In 1993, the Company recorded
     $5.9 million of contract revenues from CytoRad in addition to the licensing
     fee from CytoRad and $900,000 from Bracco.  In 1992, the Company recorded
     $6.1 million of contract revenues from CytoRad in addition to the licensing
     fee from CytoRad and an aggregate of $1.9 million from Bracco, Sterling
     Drug Inc. and Chiron.

                                      -22-

 
          Operating Expenses.  Total operating expenses were $34.8 million in
     1994, $41.3 million in 1993 and $29.8 million in 1992.  The decrease from
     1993 to 1994 reflects the Company's objective to control spending and to
     focus its efforts on its highest priorities:  marketing and sales of
     OncoScint CR/OV; phase III clinical development of Samarium EDTMP, a cancer
     therapy agent for bone pain; submission in January 1995 of the PLA with FDA
     for ProstaScint, a diagnostic agent for prostate cancer; development of
     TSARs\SynGenes; and continuation of the prostate and ovarian cancer therapy
     programs.  The increase of $11.5 million from 1992 to 1993 is largely
     attributable to selling and promotional activities associated with the U.S.
     product launch effort of OncoScint CR/OV which commenced in the first
     quarter of 1993, a reserve established in 1993 for potential inventory
     writedowns of commercial inventory relating to OncoScint CR/OV, and
     expenses associated with the settlement of a class action securities
     lawsuit.

          Research and development expenses were $20.3 million in 1994, $24.8
     million in 1993 and $21.7 million in 1992.  These expenses principally
     reflect product development efforts and support for various ongoing
     clinical trials.  Human clinical trials in 1994 included development of
     Samarium EDTMP and development on behalf of CytoRad of products for
     diagnosis and treatment of prostate cancer.  During 1994 and 1993, the
     Company charged $1.1 million and $2.3 million, respectively, to research
     and development expenses for potential inventory writedowns of commercial
     inventory relating to OncoScint CR/OV.  In July 1993, the Company
     petitioned FDA for shelf-life extension for certain commercial raw material
     inventory.  The timing and outcome of FDA's response to this request is
     uncertain.  Given the quantities of commercial raw material inventory along
     with the uncertainty of FDA's response regarding shelf-life extension for
     this inventory, future inventory writedowns may be required.

          Selling and marketing expenses were $5.5 million in 1994, $9.4 million
     in 1993 and $2.7 million in 1992.  The decrease from 1993 to 1994 and
     increase from 1992 to 1993 are primarily attributable to the $5.1 million
     recorded in 1993 for promotional expenses associated with the domestic
     launch of OncoScint CR/OV as compared to $1.5 million recorded in 1994.

          Reacquisition of technology and marketing rights expenses were $4.6
     million in 1994 and included $2.4 million and $800,000 of one-time charges
     for the reacquisition of marketing rights to OncoScint CR/OV from Knoll and
     Chiron, respectively.  In addition, the Company charged $1.4 million of
     legal and investment banking fees relating to the CytoRad merger to expense
     in 1994.

          General and administrative expenses were $4.3 million in 1994, $7.0
     million in 1993 and $5.4 million in 1992.  General and administrative
     expenses in 1993 were greater than 1992 and 1994 largely due to a reserve
     established in 1993 for the settlement of a class action securities lawsuit
     (see Note 18 to the Consolidated Financial Statements) and to higher levels
     of general legal and corporate communication expenses.

          Net Gain/Loss on Investments.  Net loss on investments for 1994 was
     $470,000 compared to net gains of $1.7 million and $3.4 million recorded in
     1993 and 1992, respectively.  The decrease in 1994 is attributable
     primarily to a $1.5 million loss associated with the sale of government
     securities due to the rise of interest rates.  This loss was partially
     offset by interest income of approximately $1.0 million in 1994.  The net
     gain on investments decreased in 1993 from 1992 by $1.7 million due to the
     decline of average cash and short term investment balances in 1993.

          Net Loss.  Net losses were $32.8 million, $29.2 million and $12.9
     million in 1994, 1993 and 1992, respectively.  Losses per share were $1.38,
     $1.38 and $0.75 in 1994, 1993 and 1992, respectively, on 23.8 million, 21.1
     million and 19.0 million average shares outstanding in each year,
     respectively.  The losses per share for 1992 included a $0.07 dividend on
     preferred stock.  There were no dividends on preferred stock in 1993 and
     1994 because on September 29, 1992, the Company called for redemption

                                      -23-

 
     of all of its outstanding Convertible Exchangeable Preferred Stock.  At
     December 31, 1994, the Company had 2.1 million options outstanding under
     its various stock option plans with exercise prices ranging from $1.00 to
     $17.00 per share, and outstanding warrants to purchase 4.3 million shares
     with exercise prices ranging from $12.50 to $24.15 per share.  The loss per
     share calculation stated above does not take into account the shares
     issuable upon exercise of such options and warrants as their effect is
     antidilutive.

     Liquidity and Capital Resources

          The Company's cash and short term investments as of December 31, 1994
     were $7.7 million, compared to $23.8 million on January 1, 1994.
     Historically, the Company's primary sources of cash have been proceeds from
     the sales of its stock through public offerings and private placements, the
     sale of research services, fees paid under its license agreements, product
     related revenues, and interest earned on its cash and short term
     investments.  In January 1994, the Company sold an aggregate of 2 million
     shares of its common stock to several European institutions, realizing net
     proceeds of $9.1 million.  In May and August of 1994, the Company sold to
     Fletcher Capital Markets, Inc. an aggregate of 1.4 million shares of common
     stock realizing net proceeds of $5.3 million.  See Note 12 to the
     Consolidated Financial Statements.  In 1994, cash used for operating
     activities of $27.6 million increased from the same period in 1993 by
     approximately $12.2 million due primarily to (i) the receipt of a $2.0
     million milestone payment from Knoll in January 1993, (ii) the receipt of
     $8.3 million in payments (excluding $3.6 million of proceeds from warrants)
     from CytoRad in 1993 and (iii) the $3.2 million non-cash charge to
     operations in 1994 for the reacquisition of marketing rights.  Cash used
     for purchases of property and equipment in 1994 was $2.8 million compared
     to $1.6 million in 1993 as a result of a project the Company began in 1993
     and completed in 1994 to create additional manufacturing capacity for
     monoclonal antibodies.

          The Company has recorded product related revenues from the sales of
     its OncoScint Colorectal product in Europe since 1992 and from sales of
     OncoScint CR/OV in the United States since January 1993.  To date, sales
     have not been significant and are not expected to become a significant
     source of cash flow in 1995.  In anticipation of the execution of the
     Termination Agreement (described below), as of May 20, 1994, Knoll ceased
     its selling efforts and since that date, the Company's direct sales force
     has been the sole marketer in the U.S. of OncoScint CR/OV.  Beginning July
     1, 1994, product related revenues have included direct product sales by the
     Company to its U.S. customers.  Since that date, the Company had not
     recorded any product sales to Knoll or any co-promotion revenues.  The
     Company is considering, with respect to the marketing of OncoScint CR/OV in
     the U.S., maintaining its direct selling efforts as well as co-promotion
     arrangements or licensing of all rights to a third party.  Depending on the
     approach selected, significant resources could be required for such action.

          On November 1, 1994, the Company executed the Termination Agreement
     with Knoll terminating the Knoll Agreement.  Pursuant to the Termination
     Agreement, the Company has reacquired from Knoll all of the U.S. Rights to
     OncoScint CR/OV.  The Termination Agreement requires the Company to pay to
     Knoll, over a four-year period and without interest, $3.0 million to
     reacquire the U.S. Rights and reschedules payment of approximately $5.0
     million of liabilities previously incurred under the terms of the Knoll
     Agreement, as follows:  $3,100,000 in 1995, $1,600,000 in 1996, $1,600,000
     in 1997 and $1,700,000 in 1998.  See Note 4 to the Consolidated Financial
     Statements.

          On December 30, 1994, the Company entered into the Disengagement
     Agreement with Chiron to reacquire the European Rights and purchase certain
     business assets relating to the European Rights, including existing
     approvals by the appropriate regulatory authorities to market OncoScint
     CR/OV in 12 countries in Europe.  This reacquisition was consummated on
     February 16, 1995.  See Note 9 to the Consolidated Financial Statements.
     The reacquisition price of $1 million, payable over three years and without
     interest, will be paid as follows:  $200,000 in 1995, $300,000 in 1996 and
     $500,000 in 1997.

                                      -24-

 
     Payment is secured by a mortgage covering approximately 11 acres of
     undeveloped real property owned by the Company and located in Ewing, New
     Jersey.  This obligation is non-recourse to the Company.

          During 1994, no payments were received by the Company from CytoRad and
     the Company did not record any contract revenues from CytoRad.  On November
     15, 1994, the Company and CytoRad entered into an agreement for the
     acquisition of CytoRad by Cytogen.  On February 23, 1995, the Company's
     shareholders approved the issuance of the Company's securities necessary to
     effect the acquisition of CytoRad and on February 27, 1995, the Company
     completed its acquisition of CytoRad by merging CytoRad with and into a
     wholly-owned subsidiary of the Company.  As a result of the merger, the
     Company will not recognize any further contract revenues from CytoRad and
     $11.7 million of CytoRad's cash and securities were transferred to the
     Company, of which approximately $2.0 million will be used in 1995 to pay
     for the merger transaction costs incurred by the Company.  See Note 3 to
     the Consolidated Financial Statements.

          In 1993, the Company acquired an exclusive license in the U.S. from
     Dow for Samarium EDTMP.  See Note 5 to the Consolidated Financial
     Statements.  Samarium EDTMP is a cancer therapy agent that is being
     developed by Cytogen as a treatment for the pain associated with bone
     metastases, a condition that occurs when cancer originates in or spreads to
     the bone.  The first of two Phase III studies for Samarium has been
     completed and the second Phase III study is currently ongoing.  Based on a
     pre-NDA meeting with FDA held in November 1994 and subsequent discussions
     with representatives from the agency, the Company expects to file its NDA
     in the first half of 1995.  Within 30 days after the filing of the NDA, the
     Company is required to pay to Dow $1,000,000.  In addition, the Company
     will be required to pay to Dow $4,000,000 if and when Samarium EDTMP
     receives FDA approval.  The agreement provides for additional payments by
     the Company upon achievement of certain milestones and royalties on net
     sales of the product once commercialized, including guaranteed minimum
     payments.

          In December 1994, Cytogen entered into a license agreement with DuPont
     Merck.  Pursuant to the terms of the DP/Merck Agreement, Cytogen received
     from DuPont Merck an up-front cash payment of $1,000,000 in December 1994,
     $4,000,000 in January 1995 for the sale to DuPont Merck of 908,265 shares
     of Cytogen common stock and $1,334,000 in January 1995 to fund additional
     clinical programs to expand the use and marketing of Samarium EDTMP.  The
     DP/Merck Agreement further provides for future payments of up to $2,916,000
     toward additional clinical programs, a $2,000,000 milestone payment if and
     when Samarium EDTMP receives FDA approval and royalty payments based on
     sales, including guaranteed minimum payments.

          In September 1989, the Company entered into an agreement with Bracco.
     Pursuant to the terms of the Bracco Agreement, in 1989, Bracco purchased
     250,000 shares of the Company's common stock (the "Shares") at $8.00 per
     share.  The Bracco Agreement provides that if the results of a feasibility
     study conducted by the Company do not meet certain predetermined evaluation
     criteria, the Company would be obligated to repurchase the Shares from
     Bracco for an aggregate purchase price of $2,000,000.  The Bracco Agreement
     further established a completion date for the feasibility study of
     September 29, 1993.  The feasibility study was not completed by that date.
     A final report on the findings of the feasibility study, which held that
     the evaluation criteria had not been met, was released on March 4, 1994.
     On July 11, 1994, Bracco notified the Company of its belief that the
     Company has an obligation to redeem the Shares.  The Company has entered
     into negotiations with Bracco to reach an agreement as to the disposition
     of the Shares and such negotiations are continuing.  There can be no
     assurances that these negotiations will be successful.

          The Company intends to pursue opportunities to acquire, in-license and
     develop other technologies or products to supplement its core products and
     technology.  If successful, this strategy may increase short

                                      -25-

 
     term expenses or increase long term revenues.  While there can be no
     assurance that these efforts will be successful, any transaction is likely
     to require payments by the Company in either cash or stock in addition to
     the costs associated with developing and marketing any product or
     technology.

          The Company's operating and capital requirements, as described above,
     may further change depending upon several factors, including:  (i) the
     amount of resources which the Company devotes to clinical evaluations and
     the establishment of manufacturing, marketing and sales capabilities; (ii)
     results of preclinical testing, clinical trials and research and
     development activities; (iii) competitive and technological developments;
     (iv) the Company's success in entering into, and cash flows derived from,
     new technology licensing, marketing and research agreements, and product
     related revenues; and (v) the Company's success in attracting additional
     capital.

          The Company plans to further control spending in 1995 and anticipates
     that its existing cash and short term investments balance of $7.7 million
     at December 31, 1994, together with payments received from DuPont Merck in
     the first quarter of 1995 and funds received as a result of the CytoRad
     merger, will be sufficient to satisfy its currently anticipated cash needs
     through 1995.  The Company anticipates receiving additional funds from
     DuPont Merck in accordance with the terms of the DP/Merck Agreement, other
     license and contract revenues, product related revenues, interest income,
     and from the sales of equity securities as market conditions permit.  There
     can be no assurance as to the Company's success in obtaining such
     additional funds or that such funds, if obtained, will be sufficient to
     meet the Company's cash requirements through the time that product related
     resources are sufficient to cover the Company's operating expenses.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



     To CYTOGEN CORPORATION:


       We have audited the accompanying consolidated balance sheets of CYTOGEN
     Corporation (a Delaware Corporation) and Subsidiary as of December 31, 1994
     and January 1, 1994, and the related consolidated statements of operations,
     redeemable common stock, preferred stock, common stock and accumulated
     deficit and cash flows for each of the three years in the period ended
     December 31, 1994.  These financial statements are the responsibility of
     the Company's management.  Our responsibility is to express an opinion on
     these financial statements based on our audits.

       We conducted our audits in accordance with generally accepted auditing
     standards.  Those standards require that we plan and perform the audit to
     obtain reasonable assurance about whether the financial statements are free
     of material misstatement.  An audit includes examining, on a test basis,
     evidence supporting the amounts and disclosures in the financial
     statements.  An audit also includes assessing the accounting principles
     used and significant estimates made by management, as well as evaluating
     the overall financial statement presentation.  We believe that our audits
     provide a reasonable basis for our opinion.

       In our opinion, the financial statements referred to above present
     fairly, in all material respects, the financial position of CYTOGEN
     Corporation and Subsidiary as of December 31, 1994 and January 1, 1994 and
     the results of its operations and its cash flows for each of the three
     years in the period ended December 31, 1994 in conformity with generally
     accepted accounting principles.

       Our audits were made for the purpose of forming an opinion on the basic
     financial statements taken as a whole.  The schedules listed in the index
     of financial statements are presented for purposes of complying with the
     Securities and Exchange Commission's rules and are not a required part of
     the basic financial statements.  These schedules have been subjected to the
     auditing procedures applied in our audits of the basic financial statements
     and, in our opinion, fairly state in all material respects the financial
     data required to be set forth therein in relation to the basic financial
     statements taken as a whole.

                                                            ARTHUR ANDERSEN LLP

                      CYTOGEN CORPORATION AND SUDSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



     1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:


     Business

       CYTOGEN Corporation ("Cytogen" or the "Company") is a biopharmaceutical
     company engaged in the discovery, development and marketing of products for
     the targeted delivery of diagnostic and therapeutic substances directly to
     sites of disease.  In January 1995, the Company filed a Product License
     Application ("PLA") with the U.S. Food and Drug Administration ("FDA") for
     ProstaScint, a prostate cancer diagnostic imaging product.  On December 29,
     1992, the Company received final regulatory approval for the sale of its
     OncoScint colorectal and ovarian cancer imaging products ("OncoScint
     CR/OV") in the United States.  In 1991, the Company received approval for
     the sale of its OncoScint colorectal cancer imaging product in Europe.  In
     order to develop, manufacture and market its products effectively, the
     Company will require additional financing.  The Company is subject to those
     risks of companies in similar stages of development.

     Basis of Consolidation

       The consolidated financial statements include the accounts of Cytogen and
     its wholly-owned subsidiary, which was formed in October 1994.
 
     Fiscal Year

       Beginning in 1994, the Company changed from a fiscal year end to a
     calendar year end.  Previously, the Company operated on a 52-53 week fiscal
     year ending on the Saturday nearest to December 31.  References to 1993 and
     1992 relate to fiscal years ended January 1, 1994 and January 2, 1993,
     respectively.

     Cash and Cash Equivalents

       Cash and cash equivalents include cash on hand, cash in banks and all
     highly-liquid investments with a maturity of three months or less at the
     time of purchase.

     Short Term Investments

       The Company adopted Statement of Financial Accounting Standards No. 115,
     "Accounting for Certain Investments in Debt and Equity Securities" ("FAS
     No. 115"), effective January 2, 1994. As permitted by FAS No. 115, the
     Company did not retroactively restate prior years' financial statements.

       Short term investments as of January 1, 1994 were stated at cost, which
     approximated market value, and consisted primarily of U.S. Treasury
     obligations, government agency paper and corporate medium term notes.
     Realized loss on the sale of securities was $1,549,000 in 1994.

     Inventory

       The Company's inventory is primarily related to OncoScint CR/OV, its
     monoclonal antibody-based imaging agent for the diagnosis of colorectal and
     ovarian cancers. Inventory is stated at the lower of cost or market using
     the first-in, first-out method and consisted of:


 
                                                        1994          1993
                                                ------------   -----------

                                                 -----------   -----------
                                                 $ 3,159,000   $ 4,088,000
                                                 ===========   =========== 


       Inventory shown as of December 31, 1994 is net of a $1,543,000 reserve.
     The Company's raw materials include an investment in monoclonal antibodies
     for commercial use, which the Company currently estimates will not be fully
     used in the foreseeable future.  In July 1993, the Company petitioned FDA
     for an extension of the shelf life of monoclonal antibodies.  As of
     December 31, 1994, approximately $2.0 million of raw materials exceeded the
     currently authorized FDA shelf life.  The realization of the Company's
     investment in raw material inventory is dependent upon the following: (i)
     the growth in product sales which, to date, has been slower than
     anticipated; and (ii) the timing and outcome of FDA's response to the
     Company's request for shelf life extension.  Given the above uncertainties
     with respect to raw materials inventory, future inventory writedowns may be
     required.

     Property and Depreciation

       Furniture and equipment are stated at cost net of depreciation and a
     $215,000 reserve for idle equipment.  Leasehold improvements are amortized
     on a straight-line basis over the lease period or the estimated useful
     life, whichever is shorter.  Equipment and furniture are depreciated on a
     straight-line basis over five years.  Expenditures for repairs and
     maintenance are expensed as incurred.  For 1994, 1993 and 1992,  repairs
     and maintenance expenses were $382,000, $310,000 and $312,000,
     respectively.

     Other Assets

       Other assets consist of undeveloped real property with a net book value
     of $1,284,000, which is valued at the lower of cost or market (see Note 9).

     Revenue Recognition

       Product related revenues include (i) product sales by the Company to its
     customers and its former U.S. and European distributors, Knoll
     Pharmaceuticals Company ("Knoll") and Chiron B.V., formerly EuroCetus B.V.,
     successor in interest to EuroCetus International, N.V. ("Chiron"),
     respectively, (ii) co-promotion revenues, which resulted from the sale of
     commercial product by Knoll to its customers, and (iii) royalty payments on
     product sales by Chiron to its customers.  Product sales are recognized
     upon shipment of finished goods.  Co-promotion revenues were recognized
     upon the shipment by Knoll of product to its customers.  Royalty revenues
     were recognized when Chiron shipped product to its customers.  Beginning on
     July 1, 1994, as a result of the Company's termination of its relationship
     with Knoll (see Note 4), product related revenues include direct product
     sales by the Company to its U.S.

                                      -44-

 
                      CYTOGEN CORPORATION AND SUBSIDIARY
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


     customers in the amount of $854,000.  Since that date, the Company has not
     recorded any product sales to Knoll or any co-promotion revenues.  See Note
     9 for discussion of the change in the Company's relationship with Chiron.

       License and contract revenues include milestone payments and fees under
     collaborative agreements with third parties, the sale of research services
     and materials, and revenues from other miscellaneous sources.  Revenues
     from milestone payments are recognized when all parties concur that the
     events stipulated in the agreement have been achieved.  Revenues from cost-
     plus contracts are recognized when the costs are incurred.

     Research and Development

       Research and development expenditures consist of projects conducted by
     the Company and payments made to sponsored research programs and
     consultants.  All research and development costs are expensed as incurred.
     Research and development expenditures for customer sponsored programs were
     $29,000, $9,112,000 and $8,868,000 in 1994, 1993, and 1992, respectively.

     Patent Costs

       Patent costs are expensed as incurred.

     Loss Per Share

       Net loss per common share is based upon the weighted average common
     shares outstanding during each period.  Common stock equivalents and other
     potentially dilutive securities are not included as their effect is
     antidilutive.  Dividends on preferred stock which were equivalent to $0.07
     per common share in 1992 are added to the net loss for the purpose of
     computing net loss per common share.

     Reclassification

       Certain reclassifications have been reflected in the 1992 and 1993
     financial statements to conform with the 1994 presentation.

     Supplemental Schedule of Noncash Financing Activity

       In 1994, the Company issued 197,942 shares of common stock in settlement
     of a lawsuit  (see Note 18).


     2.  DUPONT MERCK:

       On December 20, 1994, the Company entered into a license agreement (the
     "DP/Merck Agreement") with DuPont Merck.  Under the terms of the DP/Merck
     Agreement, the Company granted to DuPont Merck a license to the Company's
     rights to Samarium EDTMP pursuant to which DuPont Merck will have
     responsibility for manufacturing and co-marketing Samarium EDTMP in the
     U.S., if and when approved for marketing by FDA.  Samarium EDTMP is a
     cancer therapy agent that is being developed by the Company as a treatment
     for the pain associated with bone metastases, a condition that occurs when

                                      -45-

 
                      CYTOGEN CORPORATION AND SUBSIDIARY
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

     cancer originates in or spreads to the bone.  The Company acquired the U.S.
     rights to Samarium EDTMP from The Dow Chemical Company ("Dow") pursuant to
     a license agreement in March 1993 and assumed responsibility for the
     development and commercialization of the product at that time (see Note 5).
     Samarium EDTMP is currently in late Phase III clinical development.

       Pursuant to the terms of the DP/Merck Agreement, the Company received
     from DuPont Merck an up-front cash payment of $1,000,000 in December 1994,
     $4,000,000 in January 1995 for the sale to DuPont Merck of 908,265 shares
     of the Company's common stock and $1,334,000 in January 1995 to fund
     additional clinical programs to expand the use and marketing of Samarium
     EDTMP.  The DP/Merck Agreement further provides for future payments of up
     to $2,916,000 toward additional clinical programs, a $2,000,000 milestone
     payment if and when Samarium EDTMP receives FDA approval and royalty
     payments based on sales, including guaranteed minimum payments.


     3.  CYTORAD INCORPORATED:

       In a public offering by the Company and CytoRad Incorporated ("CytoRad")
     completed in March 1992, 4,025,000 units were sold, each unit consisting of
     one share of the callable common stock of CytoRad and one warrant to
     purchase one share of the common stock of the Company at $24.15 per share.
     The aggregate price to the public of the units was $40.3 million.  All of
     the approximately $37.4 million in net proceeds of the offering were paid
     to CytoRad, which was obligated to pay the Company substantially all such
     net proceeds subject to certain conditions.  The Company elected to
     amortize the $11.1 million value of the warrants, sold as part of the units
     transaction, and recorded the amortized warrant value as additional paid-in
     capital over the life of its development agreement with CytoRad in
     proportion to the amount of gross revenues received by the Company from
     CytoRad each year.  During 1994, the Company did not record any contract
     revenues from CytoRad and, therefore, no amortized warrant value was
     recorded.  In 1993 and 1992, $3,636,000 and $2,746,000 of amortized warrant
     value was recorded, respectively.  As a result of the consummation of the
     merger described below, there will be no further accounting for the
     remaining warrant value.

       In February 1992, the Company entered into a series of arrangements with
     CytoRad, which included a technology license agreement which provided for
     an up-front $3.0 million one-time payment by CytoRad as partial payment for
     a license of the prostate and bladder products utilizing the Company's
     technology, a development agreement under which the Company was to use
     funds aggregating approximately $34.9 million by 1996 which were to be
     provided by CytoRad to conduct research and development of products for the
     diagnosis and treatment of prostate and bladder cancers, a license option
     agreement which allowed the Company to acquire licenses from CytoRad to
     commercialize the products developed under the development agreement and a
     services agreement which provided for the Company to furnish certain
     administrative services to CytoRad on a fully burdened cost reimbursement
     basis.  These arrangements were modified in February 1993 to provide for a
     license from the Company to CytoRad of its ovarian cancer radiotherapy
     product and related technology in return for an up-front, non-refundable
     license fee payment to the Company of $2.0 million which was recorded in
     the first quarter of 1993.

       In March 1994, the Company was informed that CytoRad was exploring
     modifications to its then existing business relationship with the Company.
     Accordingly, CytoRad's Board of Directors did not approve the 1994
     development agreement budget.  Due to the uncertainty of the CytoRad
     business

                                      -46-

 
                      CYTOGEN CORPORATION AND SUBSIDIARY
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

     relationship, the Company did not recognize any contract revenues for
     services performed on behalf of CytoRad in 1994.  In 1993 and 1992,
     $5,903,000 and $6,064,000 of contract revenues were recognized,
     respectively, net of amortization of warrants issued.

       On November 15, 1994, the Company entered into an Agreement and Plan of
     Merger (the "Merger Agreement") with CytoRad to purchase all of CytoRad's
     outstanding units.  Pursuant to the Merger Agreement, on January 20, 1995,
     the Company commenced an exchange offer  to exchange for each CytoRad unit
     (a) 1.5 shares of the Company's common stock, (b) a warrant to acquire one
     share of the Company's common stock for $8.00 that expires January 31, 1997
     and (c) a contingent value right ("CVR") to receive, under certain
     circumstances and at no additional cost, up to one-half share of the
     Company's common stock.  The CVR will be triggered in the event that the
     aggregate trading price of 1.5 shares of the Company's common stock and the
     new warrant averages less than $12.00 during the 45 consecutive trading
     days ending January 31, 1997.  However, the CVR will expire and have no
     value if the aggregate trading price for such securities averages $12.00 or
     more during any 45 consecutive trading days prior to January 31, 1997.

       On February 23, 1995, the Company's shareholders approved the issuance of
     the Company's securities necessary to effect the acquisition of CytoRad.
     On February 24, 1995, the Company  announced that it had completed the
     exchange offer, pursuant to which approximately 93% of the outstanding
     CytoRad units were validly tendered.  On February 27, 1995, the Company
     issued 5,622,698 shares of common stock, 3,748,468 CVRs and 3,748,468
     warrants pursuant to the exchange offer.  In addition, the Company
     announced on February 27, 1995 that it had completed its acquisition of
     CytoRad by merging CytoRad with and into a wholly-owned subsidiary of the
     Company.  Holders of CytoRad common stock who did not tender their CytoRad
     units in the exchange offer became entitled to receive as a result of the
     merger one and one-half shares of the Company's common stock and one CVR
     for each share of CytoRad common stock owned thereby.  Although the 276,532
     previously issued Cytogen warrants forming a part of CytoRad units not
     tendered in the exchange offer will remain outstanding after the merger,
     the Company has agreed that such warrants will be exercisable at $8.00 per
     warrant share pursuant to the terms of the Merger Agreement.  As a result
     of the merger, the Company reacquired the product rights to the prostate,
     ovarian and bladder products it had previously licensed to CytoRad.  In
     addition, the Company will not recognize any further contract revenues from
     CytoRad and $11.7 million of CytoRad's cash and securities were transferred
     to the Company.  The Company estimates that it will record in the first
     quarter of 1995 approximately $20 million for acquired research and
     development on its statement of operations, representing the amount by
     which the purchase price exceeds CytoRad's net book value.  This estimated
     charge to the statement of operations may change based upon the Company's
     final accounting for this transaction.


     4. KNOLL PHARMACEUTICAL COMPANY:

       The Company and Knoll entered into a license, supply and marketing
     agreement in December 1991 (the "Knoll Agreement") for the co-promotion of
     OncoScint CR/OV in the United States.  The agreement provided for revenues
     from milestone payments to the Company, the last of which was received in
     1992, revenues from product sales from the supply of commercial product by
     the Company to Knoll, co-promotion revenues from the sale of commercial
     product by Knoll to its customers, and reimbursement to the Company of
     certain product development expenses.  The Company also agreed to share
     with Knoll certain sales promotion expenses which were to be paid by the
     Company from earned co-promotion

                                      -47-

 
     revenues.  In 1994 and 1993, the Company incurred $412,000 and $5,100,000,
     respectively, in co-promotion expenses and recognized $430,000 and
     $977,000, respectively, in co-promotion revenues.

       On November 1, 1994, the Company executed a termination agreement with
     Knoll (the "Termination Agreement").  Pursuant to the Termination
     Agreement, the Company has reacquired from Knoll all U.S. marketing rights
     (the "U.S. Rights") to OncoScint CR/OV.  The Termination Agreement requires
     the Company to pay to Knoll, over a four-year period and without interest,
     $3.0 million to reacquire the U.S. Rights and reschedules the payment of
     approximately $5.0 million of liabilities previously incurred under the
     terms of the Knoll Agreement, as follows:  $3,100,000 in 1995, $1,600,000
     in 1996, $1,600,000 in 1997 and $1,700,000 in 1998.  In 1994, the Company
     recorded a non-recurring charge of $2.4 million for the reacquisition of
     the U.S. Rights.  Imputed interest of $328,000 relating to the obligation,
     which was discounted for accounting purposes at 10%, was also recorded in
     1994.

       In anticipation of the execution of the Termination Agreement, as of May
     20, 1994, Knoll ceased its selling efforts, and since that date, the
     Company's direct sales force has been the sole marketer in the U.S. of
     OncoScint CR/OV, which is approved by FDA for the imaging of colorectal and
     ovarian cancer.  The Company is considering, with respect to the marketing
     of OncoScint CR/OV in the U.S., maintaining its direct selling efforts as
     well as co-promotion arrangements or licensing of all rights to a third
     party.

       Under the terms of an Order Fulfillment Agreement effective November 1,
     1994, Knoll will continue to provide warehousing, shipping, invoicing  and
     collection services for the Company until June 30, 1995.  As of December
     31, 1994, Knoll owes the Company $722,000 for outstanding receivables, net
     of distribution fees.  This amount was reflected as a reduction of the
     Company's liability due to Knoll inasmuch as the right of offset exists.


     5.  THE DOW CHEMICAL COMPANY:

       In 1993, the Company acquired an exclusive license in the U.S. from Dow
     for Samarium EDTMP and related technology.  In connection with this
     acquisition, the Company issued to Dow warrants to purchase 260,000 shares
     of the Company's common stock at $12.50 per share.  The Company valued the
     warrants at $507,000 and recorded this amount as a charge to research and
     development expense.  The agreement also provides for certain payments by
     the Company to Dow upon the achievement of certain milestones in the
     regulatory approval process and to pay royalties on net sales of the
     product.

       At December 31, 1994, the Company had an unused secured line-of-credit of
     $3,000,000 expiring in July 1996. Interest rates on any borrowings under
     the line-of-credit will vary depending on the amounts borrowed. The Company
     did not have any borrowings outstanding under the line-of-credit in 1994.

       On December 30, 1994, the Company entered into a disengagement agreement
     (the "Disengagement Agreement") with Chiron.  Pursuant to a Distribution
     and License Agreement dated as of October 21, 1989 and as amended on May
     18, 1992, the Company granted to Chiron exclusive marketing and
     distribution rights in Europe (the "European Rights") to OncoScint CR/OV,
     under which contract and product related revenues of $162,000, $164,000 and
     $377,000 were recognized in 1994, 1993, and 1992, respectively.  Under the
     Disengagement Agreement, the Company reacquired the European Rights and
     purchased certain business assets relating to the European Rights,
     including existing approvals by the appropriate regulatory authorities to
     market OncoScint CR/OV in 12 countries in Europe.  This reacquisition was
     consummated on February 16, 1995.  The reacquisition price of $1 million,
     payable over three years and without interest, will be paid as follows:
     $200,000 in 1995, $300,000 in 1996 and $500,000 in 1997.  The liability was
     discounted at 10% for accounting purposes.  Payment is secured by a
     mortgage covering approximately 11 acres of undeveloped real property owned
     by the Company in Ewing, New Jersey.  This obligation is non-recourse to
     the Company.  The Company had a receivable

                                      -49-

 
                      CYTOGEN CORPORATION AND SUBSIDIARY
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


     of approximately $125,000 due from Chiron at December 31, 1994, which will
     be offset against the amount due Chiron under the Disengagement Agreement.
     This receivable is reflected as a reduction of the amount due Chiron in the
     accompanying balance sheet.  As a result of the reacquisition of the
     European Rights, the Company recorded a non-recurring charge of $800,000
     in the fourth quarter of 1994.  The Company intends to secure alternative
     marketing and distribution partners for OncoScint CR/OV in Europe and
     Japan.  Until the earlier of (i) an agreement with a new distributor, or to
     (ii) December 31, 1995, Chiron will continue to provide warehousing and
     distribution services to the Company.


     10.  REDEEMABLE COMMON STOCK:

       In 1989, the Company entered into an agreement (the "Bracco Agreement")
     with Bracco Industria Chimica S.p.A. ("Bracco") granting Bracco an
     exclusive option to license magnetic resonance imaging enhancement agents
     using the Company's linking technology.  Pursuant to the terms of the
     Bracco Agreement, in 1989, Bracco purchased 250,000 shares of the Company's
     common stock (the "Shares") at $8.00 per share.  The Bracco Agreement
     provides that if the results of a feasibility study conducted by the
     Company do not meet certain predetermined evaluation criteria, the Company
     would be obligated to repurchase the Shares from Bracco for an aggregate
     purchase price of $2,000,000.  The Bracco Agreement further established a
     completion date for the feasibility study of September 29, 1993.  The
     feasibility study was not completed by that date.  A final report on the
     findings of the feasibility study, which held that the evaluation criteria
     had not been met, was released on March 4, 1994.

       On July 11, 1994, Bracco notified the Company of its belief that the
     Company has an obligation to redeem the Shares.  The Company has entered
     into negotiations with Bracco to reach an agreement as to the disposition
     of the Shares and such negotiations are continuing.  There can be no
     assurances that these negotiations will be successful.

       Under the Bracco Agreement, contract revenues of $41,000, $860,000 and
     $1,343,000 were recognized in 1994, 1993, and 1992, respectively.


     11.  REDEEMABLE PREFERRED STOCK:

       In 1989 and 1990, 690,000 shares of the Company's $2.50 Convertible
     Exchangeable Preferred Stock (the "Convertible Preferred Stock") were sold
     for $25.00 per share, realizing net proceeds of $15,680,000.  Each share of
     the Convertible Preferred Stock was entitled to cumulative dividends of
     $2.50 per share per year, was convertible into 3.55 shares of common stock
     at the option of the holder, and was redeemable by the Company under
     certain circumstances.

                                      -50-

 
                      CYTOGEN CORPORATION AND SUBSIDIARY
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


       On September 29, 1992, the Company called for redemption of all of its
     outstanding Convertible Preferred Stock at a price of $26.75 per share.
     The Company established a redemption date of October 15, 1992.  Prior to
     the redemption date, an aggregate of 688,454 shares of Convertible
     Preferred Stock were tendered for conversion into common stock.  A total of
     1,546 shares of Convertible Preferred Stock were redeemed on the redemption
     date for $41,000.  As a result of the conversion and redemption, none of
     the shares of Convertible Preferred Stock remains outstanding.


     12.  COMMON STOCK:

       In January 1994, the Company sold an aggregate of 2 million shares of
     common stock to several European institutions, realizing net proceeds of
     $9.1 million.

       On May 6, 1994, the Company and Fletcher Capital Markets, Inc.
     ("Fletcher") entered into a revised investment agreement under which
     Fletcher (i) purchased 500,000 shares of the Company's common stock at a
     price of $3.50 per share totalling $1.7 million, (ii) purchased an
     additional 900,000 shares of the Company's common stock in August 1994 at
     $4.00 per share totalling $3.6 million and (iii) received an option
     exercisable until August 12, 1995 to purchase an amount of the Company's
     common stock which, together with the shares previously purchased, will
     represent up to 9.9% of the Company's outstanding common stock on the date
     of exercise of the option.  The exercise price of the option will be 95% of
     the average daily closing prices during the 60 trading days prior to the
     date Fletcher elects to exercise its option.  The shares involved in this
     transaction were registered pursuant to a registration statement on Form S-
     3 filed with the Securities and Exchange Commission on April 6, 1994, as
     amended.  Fletcher has since assigned its rights under the option to
     Harvard Management Company, Inc.

       See Notes 2, 3 and 18 for information related to the Company's issuance
     of common stock in connection with the DP/Merck Agreement, CytoRad merger
     and settlement of shareholders litigation, respectively.  See Note 10 for
     discussion of redeemable common stock.


     13.  STOCK OPTIONS AND GRANTS:

        The Company has various stock option plans which provide for the
     issuance of incentive and non-qualified stock options to employees, non-
     employee directors and outside consultants, for which an aggregate of
     4,070,500 shares of common stock have been reserved.  The persons to whom
     options may be granted and the number, type, and terms of the options vary
     among the plans.  Options are granted with an exercise term of 10 years and
     generally become exercisable in installments over periods of up to 5 years
     at an exercise price determined either by the plan or equal to the fair
     market value of the common stock at the date of grant.  Under certain
     circumstances, vesting may accelerate.  In September 1993, the Company

        At December 31, 1994, 637,400 shares were exercisable and 1,214,195
     shares were available for issuance of additional options that may be
     granted under the plans.

        In 1994, 1993 and 1992, respectively, 10,000, 500 and 2,000 shares of
     common stock were granted to an officer of the Company and to members of
     the Company's Scientific Advisory Board.  The expense related to these
     commitments to grant shares of stock is based upon the fair value of those
     shares on the date of the commitment and is recognized over the period
     beginning with such commitment and ending with the actual grant.


     14.    RELATED PARTY TRANSACTIONS:

        Consulting services are provided under agreements with  companies owned
     by an officer of the Company and one of the Company's principal
     stockholders, both of whom are members of the Board of Directors.  The
     annual fees under the agreements were $180,000, $61,900 and $25,000 in
     1994, 1993 and 1992, respectively.

                      CYTOGEN CORPORATION AND SUBSIDIARY
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

       The seven members of the Company's Scientific Advisory Board were
     stockholders and provided consulting services to the Company in 1993 and
     1992. Consulting fees, including fees including stock grants, paid to the
     five non-employee members totaled $47,000 and $50,000 in 1993 and 1992,
     respectively.

     15.  PENSION PLANS:

       The Company maintains a defined contribution pension plan. The
     contribution is determined by the Board of Directors each year and is based
     upon a percentage of gross wages of eligible employees. The plan provides
     for vesting over five years, with credit given for prior service. The
     Company also makes contributions under a 401(k) plan in amounts which match
     up to 50% of the salary deferred by the participants. Matching is capped at
     6% of deferred salaries. Total pension expense was $256,000, $335,000 and
     $331,000 for 1994, 1993 and 1992, respectively.

     16.  INCOME TAXES:
                                                                     
       As of December 31, 1994, the Company had federal net operating loss
     carryfowards of approximately $100 million.  The Company also had federal
     and state research and development tax credit carryfowards of approximately
     $4 million.  The net operating loss and credits carryfowards will begin to
     expire in 1995, if not utilized.

        The Tax Reform Act of 1986 contains provisions that limit the
     utilization of net operating loss and tax credit carryfowards if there has
     been a "change of ownership".  Such a "change of ownership" as described in
     Section 382 of the Internal Revenue Code may limit the Company's
     utilization of its net operating loss and tax credit carryfowards.

        Deferred income taxes reflect the net tax effect of temporary
     differences between the carrying amounts of assets and liabilities for
     financial reporting purposes and the amount used for income tax purposes.
     Based upon the Company's earnings history, a valuation allowance for
     deferred tax assets is required to reduce the Company's net deferred tax
     assets to the amount realizable at present (zero).

        Significant components of the Company's deferred tax assets for federal
     and state income taxes are as follows (in thousands):


                                                             1994       1993

     17.  COMMITMENTS AND CONTINGENCIES:

        The Company leases its administrative and research facilities.  Rent
     expense incurred on these leases was $1,247,000, $1,301,000 and $1,519,000
     in 1994, 1993 and 1992, respectively.  Minimum future obligations under
     these leases total $7,143,000 as of December 31, 1994 and will be paid as
     follows:  $1,099,000 in 1995, $1,293,000 in 1996, $1,057,000 in 1997,
     $799,000 in 1998, $842,000 in 1999 and an aggregate of $2,053,000 in 2000
     through 2003.

        The Company has an agreement which provides for equipment lease
     financings.  As of December 31, 1994, the Company has $2,966,000 in sale-
     leaseback refinancings of which approximately $1.2 million was outstanding
     against this arrangement.  The refinancings resulted in a deferred gain
     which is being amortized over the lease term of 45 months.  The sale-
     leaseback refinancings are secured by $358,200 in standby letters of credit
     provided under a letter of credit agreement.  Minimum future obligations
     under these and other non-cancelable leases totalled $608,100 at December
     31, 1994 and will be incurred as follows:  $413,400 in 1995, $181,500 in
     1996 and $13,200 in 1997.

        The Company is obligated to make minimum future payments under research
     and development contracts which expire at various times.  As of December
     31, 1994, the minimum future payments under contracts with fixed terms
     totalled $593,000 and will be paid as follows:  $270,000 in 1995 and
     $323,000 in 1996.  Under contracts whose expirations are not fixed, the
     annual minimum payments are $27,500 in future years.  In addition, the
     Company is obligated to pay royalties on revenues from commercial products
     developed from the research, including certain guaranteed minimum payments.


     18.  LITIGATION:

        In September 1992, a class action securities law suit was filed.  On
     November 18, 1994, final approval was given to the settlement of that law
     suit, which provided for a $1,950,000 cash payment (which includes
     approximately $900,000 of fees and expenses of plantiffs' counsel), the
     issuance of 197,942 shares of the Company's common stock and an additional
     $500,000 payable if the Company has annual earnings per share of $.50 or
     greater during any fiscal year commencing with 1993 through 1996. The cost
     of the settlement was recorded as a liability at January 1, 1994.
