Item 1.   Business

   GENERAL OVERVIEW

     Background

     Progenics Pharmaceuticals,  Inc. ("Progenics"  or  the  "Company")  is  a
biopharmaceutical company focusing on the development and commercialization of
innovative products  for the  treatment and  prevention of  cancer, viral  and
other life-threatening diseases.  The Company applies its immunology expertise
to develop  biopharmaceuticals that  induce an  immune response  or that mimic
natural immunity  in order  to fight  cancers, such as malignant melanoma, and
viral diseases,  such  as  human  immunodeficiency  virus  ("HIV")  infection.
Progenics' most advanced product candidate, GMK, is a therapeutic vaccine that
is currently  undergoing  two  pivotal  Phase  III  clinical  trials  for  the
treatment of  melanoma, a  deadly form  of skin  cancer.    Progenics'  second
vaccine product  candidate, MGV,  is being  developed  for  the  treatment  of
various cancers.   A  Phase I/II clinical trial for MGV was completed in 1998.
Based on  its participation in the discoveries of two major receptors for HIV,
the Company  is engaged  in research  and development  of therapeutic products
designed to  block entry  of HIV  into human  immune system  cells.  Progenics
commenced Phase  I/II clinical  trials of one of these product candidates, PRO
542, in  1997, one of which was completed in 1998, and plans to initiate Phase
I/II clinical  trials of  another product  candidate, PRO  367, in  1999.  The
Company has  entered into  a collaboration  with Bristol-Myers  Squibb Company
("BMS") to  develop and  commercialize GMK  and MGV.   The  Company  has  also
entered into  a collaboration  with the  Roche  Group  of  Basel,  Switzerland
("Roche") to  discover and develop novel small-molecule HIV therapeutics which
target the recently identified fusion co-receptors of the virus.

          Cancer Therapeutics

     The Company's  GMK and  MGV cancer  therapeutics are based on proprietary
ganglioside conjugate  vaccine technology  designed to  stimulate  the  immune
system to  destroy cancer  cells.   This technology is exclusively licensed by
the Company  from Memorial  Sloan-Kettering Cancer Center ("Sloan-Kettering").
GMK is  designed to prevent recurrence of melanoma in patients who are at risk
of relapse  after surgery.   GMK is composed of a ganglioside antigen abundant
in melanoma  cells, conjugated  to an immunogenic carrier protein and combined
with an  adjuvant (an  immunological stimulator).  In August 1996, the Company
commenced the  first of  three planned  pivotal, randomized, multicenter Phase
III clinical  trials of  GMK.   This trial  is being  conducted in  the United
States by  cooperative cancer research groups supported by the National Cancer
Institute ("NCI") and had enrolled over 50% of its targeted number of patients
by early  1998.   The two  additional Phase III clinical trials of GMK will be
conducted in a number of countries outside of the United States.  One of these
trials commenced  enrollment of  patients in  June 1997.   The  other trial is
expected to  commence in  1999 and will be conducted in Europe by the European
Organization for Research and Treatment of Cancer ("EORTC").

<PAGE>
     MGV is  being developed  to treat  a wide  range  of  cancers,  including
colorectal cancer,  lymphoma, small  cell lung cancer, sarcoma, gastric cancer
and neuroblastoma.   The  American Cancer Society estimated that these cancers
would have  an aggregate incidence in the United States of over 260,000 during
1998.   The Company  believes that  MGV, which  incorporates  two  ganglioside
antigens that are abundant in these and other types of cancer cells, may be an
attractive adjunctive  therapy to  prevent  recurrence  after  the  cancer  is
removed surgically  or reduced  by chemotherapy  or radiation  therapy.    The
Company completed  Phase I/II  clinical trials  with MGV at Sloan-Kettering in
1998.

     In July  1997, the  Company and  BMS entered into a Joint Development and
Master License  Agreement (the "BMS License Agreement") and related agreements
under which  Progenics granted  BMS an  exclusive worldwide license to GMK and
MGV.   BMS made  cash payments  to the  Company of $13.3 million and agreed to
make further payments of up to $61.5 million upon the achievement of specified
milestones.   In June  1998 Progenics announced that it had received a payment
under its  collaboration with  BMS for  achieving a  clinical milestone in the
development of  GMK.   In addition, BMS is required to fund continued clinical
development of GMK and MGV and to pay royalties on any product sales.

          HIV Therapeutics

     The currently  approved HIV therapeutics, protease inhibitors and reverse
transcriptase inhibitors,  have persistent  problems of  viral resistance  and
drug toxicity.   In  contrast  to  these  therapeutics,  which  inhibit  viral
replication after HIV has infected a cell, the Company's products are designed
to prevent  infection of  healthy immune  system cells  by targeting  specific
extracellular receptors  and the  viral protein that binds to these receptors.
Binding of  the virus to the CD4 receptor and to the CCR5 or CXCR4 co-receptor
is necessary for attachment, fusion and entry of the virus into the cell.  The
Company believes  that, because the portion of the viral protein that binds to
CD4 and to the fusion co-receptors is highly conserved, the likelihood of drug
resistance to  the Company's  product candidates  through  viral  mutation  is
minimized.   Additionally, the  molecular structures of CD4, CCR5 and CXCR4 do
not vary  from person to person, making these receptors particularly appealing
targets for  drug development.    The  Company  is  engaged  in  research  and
development  programs   targeting  both   the  CD4  receptor  and  the  fusion
co-receptors CCR5 and CXCR4.

     Progenics' PRO  542 and  PRO 367 product candidates utilize the Company's
proprietary CD4  receptor technology.  Progenics  is  developing  PRO  542  to
selectively target  HIV and prevent it from infecting healthy cells by binding
to the  sites on the virus that are required for entry into the cell.  PRO 542
is being  developed as  an immunotherapy  to treat  asymptomatic  HIV-positive
individuals and  has been  shown in  vitro to  neutralize a  wide range of HIV
clinical strains.  The Company initiated Phase I/II clinical trials of PRO 542
in September  1997, one  of which was completed in 1998, and has established a
collaboration with  Genzyme Transgenics  Corporation  ("Genzyme  Transgenics")
designed to  enable commercial  scale production  by producing  PRO 542 in the
milk of transgenic animals.

     Progenics is  developing PRO  367 as a therapeutic agent designed to kill
HIV-infected cells.  PRO 367 consists of an antibody-like molecule linked to a
therapeutic radioisotope  and is  designed to bind to and destroy HIV-infected
cells by  delivering a  lethal dose  of radiation.  The Company plans to begin
Phase I/II clinical trials of PRO 367 in 1999.

     In December  1997 the  Company entered into a collaboration with Roche to
discover and  develop novel  small-molecule HIV  therapeutics that  target the
fusion co-receptors,  including CCR5  and CXCR4.    Under  the  terms  of  the
collaboration, Roche  has  received  from  Progenics  an  exclusive  worldwide
license to certain aspects of the Company's HIV co-receptor technology.  Roche
is obligated  to make up-front and milestone payments, fund research for up to
three years  and pay royalties on the sale of any products commercialized as a
result of  the collaboration.   In  addition, in June 1998 the Company entered
into a  collaboration with  Pharmacopeia, Inc.  ("Pharmacopeia")  to  discover
small-molecule HIV therapeutics that block the attachment of the virus to CD4.


                                      2
<PAGE>
     The  Company   recently  announced  that  it  was  developing  monoclonal
antibodies capable  of blocking  virus-cell fusion.   One of these antibodies,
designated PRO  140, inhibited  HIV  fusion  at  concentrations  that  had  no
apparent effect on the normal function of CCR5.

     The Human Immune System

     The human  immune system  protects the  body from disease by specifically
recognizing and  destroying foreign  invaders, including viruses and bacteria.
In addition,  the immune system is capable of recognizing and eliminating from
the body  abnormal cells, such as cancer cells and cells infected with viruses
and bacteria.   White  blood cells, particularly B and T lymphocytes, have the
ability to  recognize antigens  made by  these infectious  agents and abnormal
cells and  react to  them.  For example, B lymphocytes produce antibodies that
recognize specific  antigens.   Antibodies can  bind  to  these  antigens  and
neutralize or  eliminate infectious  agents and  cancer cells.   Vaccines  are
designed to induce the production of antibodies against antigens on infectious
agents and abnormal cells and thereby protect the body from illness.  Although
vaccines  have   historically  been   used  prophylactically  to  prevent  the
contraction of  an infectious  disease, more  recently vaccines are also being
developed as  therapeutics to  fight ongoing  diseases.   In addition, genetic
engineering techniques  have enabled the production of antibodies or antibody-
like molecules  in  the  laboratory.    These  genetically  designed  antibody
molecules are  intended to  mimic the body's own immune response in situations
where the immune response has been suppressed or otherwise compromised.

     Product Development

     The Company  applies its  expertise in  immunology to  the development of
therapeutic biopharmaceuticals  that use  components  of  the  immune  system,
particularly antibodies,  to fight  diseases.   The  Company's  two  principal
programs are  directed towards  cancer and  HIV.   In the  case of cancer, the
Company is  developing vaccine  products that  are designed to induce specific
antibody responses  to cancer  antigens.   In the  case of HIV, the Company is
developing therapeutic  products by  genetically  engineering  molecules  that
function as  antibodies and  selectively target HIV and HIV-infected cells for
neutralization or  destruction.   The Company  also  is  actively  engaged  in
research and  discovery of  compounds based  on the HIV receptor, CD4, and HIV
co-receptors, including  CCR5 and  CXCR4, and their roles in viral attachment,
fusion  and   entry.     In  addition,  the  Company  recently  announced  the
commencement of  a  research  and  development  program  to  develop  DHA,  an
antioxidant and  chemical precursor  to vitamin  C, as  a therapeutic for free
radical damage caused by autoimmune diseases, vascular catastrophic events and
other states of oxidative stress.

     Cancer Therapeutics

     Cancer is  a set of different diseases, each of which is characterized by
aberrations in  cell growth and differentiation.  The establishment and spread
of a  tumor is  a function  of its  growth characteristics  and its ability to
suppress or  evade the  body's normal  defenses,  including  surveillance  and
elimination of  cancer cells  by the  immune system.  Eradication of malignant
cells which  can metastasize (i.e., spread) to vital organs, leading to death,
is central to the effective treatment of cancer.

     Despite recent  advances in treatment, therapies for many types of cancer
continue to  suffer from  serious limitations.   The  principal therapies  for
cancer  have  historically  been  surgery,  radiation  and  chemotherapy.    A
significant drawback to conventional anti-cancer therapy is that occult (i.e.,
hidden) or  residual disease  is difficult  or impossible  to eliminate fully,
which can  lead to  relapse.   Surgery may be used to remove primary masses of
some solid  tumors; however,  it cannot  be used  to  remove  occult  disease.
Conventional treatment  with combination chemotherapy and radiation may not be
capable of eradicating cancers completely because of inadequate potency at the
tumor site  resulting from  limitations on  drug or  radiation  doses  due  to
potential side-effects  to healthy  tissues.   Moreover, while  more  recently
introduced  biological   drugs,  such  as  interferons,  have  in  some  cases
represented an  improvement over  traditional  cytotoxic  therapy,  they  have
proven effective  only on  a limited basis and only in certain types of cancer
and have adverse side effects.

     Because of  the inability  of traditional  cancer  therapies  to  address
adequately occult  and residual  cancers, non-specific  toxicities and limited
potency, a  significant need  exists for new therapeutic products.  To address
this demand,  cancer vaccines are now being developed to stimulate the natural
defense mechanisms  of the  immune system to fight cancer.  Unlike traditional
infectious disease  vaccines that are used to prevent infection in the general
population, most  cancer vaccines are therapeutic, meaning that they are being
developed to  prevent recurrence  of cancer  in  people  whose  cancer  is  in
remission following  treatment by  conventional therapies  (including surgical
removal).   In some  cases, cancer vaccines are also being designed for use in
the prevention of cancer in individuals who are at high risk for the disease.

     A major  challenge in  cancer vaccine  development results  from the fact
that the  natural human  immune response generally does not produce sufficient
antibodies to  fight cancer  cells because  the immune  system often  does not
recognize the difference between normal cells and cancer cells.  Consequently,
a primary  objective in  the development  of cancer  vaccines is  to train the
immune system  to recognize cancer cells as a threat.  If this can be achieved
and the  immune system  can produce  sufficient antibodies to the cancer, then
the recurrence  of the  cancer may  be prevented.   Most  cancer  vaccines  of
parties other  than the  Company that  are in  clinical development consist of
dead cancer  cells or  crude extracts  from cancer cells. Unlike the Company's
vaccine technology,  these  approaches  are  limited  by  their  inability  to
identify the  active components  of the  vaccine or  measure  specific  immune
responses.

          Progenics' Technology: Ganglioside Conjugate Vaccines

     Progenics'  cancer   vaccine  program   involves  the   use  of  purified
gangliosides  as   cancer  antigens.     Gangliosides  are  chemically-defined
molecules composed of carbohydrate and lipid components.  Certain gangliosides
are usually  found in  low amounts in normal human tissue, but are abundant in
certain cancers,  such as  melanoma, colorectal  cancer, lymphoma,  small cell
lung cancer, sarcoma, gastric cancer and neuroblastoma.

     Because gangliosides  alone do not normally trigger an immune response in
humans, Progenics  attaches gangliosides  to large, highly immunogenic carrier
proteins to  form "conjugate"  vaccines designed  to trigger  specific  immune
responses to  ganglioside antigens.   To further augment this immune response,
Progenics adds  an immunological  stimulator, known  as an  "adjuvant," to its
ganglioside-carrier protein conjugate.

     The Company's  ganglioside conjugate vaccines stimulate the immune system
to produce specific antibodies to ganglioside antigens.  These antibodies have
been shown  in vitro  to recognize  and destroy  cancer cells.  Based on these
tests and  the clinical  trial results  described below,  the Company believes
that vaccination  of cancer  patients with ganglioside conjugate vaccines will
delay or prevent recurrence of cancer and prolong overall survival.


                                      5
<PAGE>
     The Company's  cancer vaccines  use known  amounts of  chemically-defined
antigens, not  dead cancer  cells or  crude extracts  from cancer cells.  As a
result, Progenics  is  able  to  measure  specific  immune  responses  to  the
gangliosides in  its vaccines.   The  Company also  believes that  there is  a
reduced likelihood  of variability  in its  products as  compared to  vaccines
which are  prepared from dead cancer cells or crude extracts from cancer cells
or which require complicated manufacturing processes.

          GMK: Therapeutic Vaccine for Malignant Melanoma

     Progenics' most  advanced product under development is GMK, a proprietary
therapeutic vaccine  for melanoma  that is  currently  in  pivotal  Phase  III
clinical trials.   The Company is collaborating with BMS on this program.  GMK
is the  first cancer  vaccine based on a defined cancer antigen to enter Phase
III clinical  trials.   GMK is  designed to  prevent recurrence of melanoma in
patients who  are at  risk of  relapse after  surgery.  GMK is composed of the
ganglioside GM2  conjugated to  the carrier  protein keyhole limpet hemocyanin
("KLH") and  combined with  the adjuvant QS-21.  QS-21 is the lead compound in
the  Stimulon_   family  of   adjuvants  developed   and   owned   by   Aquila
Biopharmaceuticals Inc. ("Aquila").

          Target Market

     Melanoma is  a highly  lethal cancer  of the  skin cells that produce the
pigment melanin.   In  early stages  melanoma is  limited to  the skin, but in
later stages  it spreads  to the  lungs, liver,  brain and  other organs.  The
Company estimates  that there  are 300,000  melanoma patients  in  the  United
States today.   The  American Cancer Society estimates that 44,200 patients in
the United States will be newly diagnosed with melanoma in 1999.  Melanoma has
one of  the fastest growing incidence rates in the United States.  Projections
indicate that  for Americans  living in  the year  2000 the  lifetime risk  of
developing melanoma  is one  in 75,  compared to one in 135 in 1987 and one in
250 in  1980.  Increased exposure to the ultraviolet rays of the sun may be an
important factor contributing to the increase in new cases of melanoma.

     Melanoma patients  are categorized  according to  the  following  staging
system:

                               Melanoma Staging
  ---------------------------------------------------------------------------
      Stage I             Stage II            Stage III           Stage IV
  -----------------   -----------------   ------------------   --------------
  Lesion less than    lesion greater      metastasis to         distant
   1.5 mm thickness    than 1.5 mm         regional draining     metastasis
                       thickness           lymph nodes

  No apparent         local spread from   regional spread       
   metastasis          primary cancer      from primary
                       site                cancer site


     GMK is  designed for the treatment of patients with Stage II or Stage III
melanoma.   It is  estimated that these patients comprise approximately 50% of
the total  number of melanoma patients and, accordingly, the Company estimates
that there  are currently  150,000 Stage  II and  III melanoma patients in the
United States.   According to the American Cancer Society, an estimated 60% to
80% of  Stage III melanoma patients will experience recurrence of their cancer
and die within five years after surgery.

          Current Therapies

     Standard treatment for melanoma patients includes surgical removal of the
cancer.   Thereafter, therapy  varies depending  on the  stage of the disease.
For Stage  I and  II melanoma  patients, treatment generally consists of close
monitoring for recurrence.  The only approved treatment for Stage III melanoma
patients is  high-dose alpha  interferon.   In a  recently reported study, the
median recurrence-free survival period after surgery for patients treated with
high-dose alpha  interferon was  20 months  versus 12  months for patients who
received no  treatment.  In addition, the median overall survival period after
surgery was 46 months for the treated group versus 34 months for the untreated
group.   However, treatment with high-dose alpha interferon causes substantial
toxicities, requires  an intensive  treatment over  twelve months (intravenous
injections five  days a  week for  the first  month followed  by  subcutaneous
injections three times a week for the remaining eleven months) and costs about
$35,000 per year.


                                      6
<PAGE>
     Other approaches  for treatment  of Stage II or III melanoma patients are
currently under  investigation, but  none has  been  approved  for  marketing.
These experimental  therapies include  chemotherapy, low-dose alpha interferon
and other vaccines.

          Clinical Trials

     GMK entered  pivotal Phase  III clinical  trials in  the United States in
August 1996.   In addition, Progenics plans to conduct two international Phase
III clinical  trials of  GMK, one of which commenced enrollment of patients in
June 1997  and the  other of  which is  expected to  commence in 1999.  GMK is
administered in  the studies  on  an  out-patient  basis  by  12  subcutaneous
injections over a two-year period.

     The ongoing  U.S. Phase  III clinical  trial compares  GMK with high-dose
alpha interferon  in Stage  IIb (advanced  Stage II)  and Stage  III  melanoma
patients who have undergone surgery but are at high risk for recurrence.  This
randomized trial,  which is  expected to  enroll 850 patients and had enrolled
over 50% of these patients by early 1998, is being conducted nationally by the
Eastern Cooperative  Oncology Group ("ECOG") in conjunction with the Southwest
Oncology Group  ("SWOG") and  other major  cancer centers,  cooperative cancer
research groups, hospitals and clinics.  ECOG and SWOG are leading cooperative
cancer research  groups supported  by the  NCI and  are comprised  of  several
hundred participating  hospitals and  clinics, primarily in the United States.
The primary  endpoint of the trial is to compare the recurrence of melanoma in
patients  receiving   GMK  versus   in  patients   receiving  high-dose  alpha
interferon.   The study will also compare quality of life and overall survival
of patients in both groups.

     The second  Phase  III  clinical  trial  is  a  randomized  double-blind,
placebo-controlled study in Stage IIb and Stage III melanoma patients who have
undergone surgery  but are  at high  risk for  recurrence.   This trial, which
enrolled its  first patients  in June  1997, will be conducted by major cancer
centers, hospitals and clinics in Europe, Australia, New Zealand, South Africa
and South  America.  In the United Kingdom, the study will be conducted by the
Institute  of   Cancer  Research  ("ICR")  of  the  United  Kingdom,  a  major
government-sponsored cancer  research organization.   The  primary endpoint of
the trial  is to  compare the recurrence of melanoma in patients receiving GMK
versus in  patients receiving  placebo.   The study  will also compare overall
survival of patients in both groups.

     The third Phase III clinical trial will be a randomized study exclusively
in Stage IIa (early Stage II) melanoma patients who have undergone surgery but
are at  intermediate risk  for recurrence.   This  trial,  which  the  Company
expects will  commence in  1999, will be conducted in Europe by the EORTC, the
major  cooperative  cancer  research  group  in  Europe.    Patients  will  be
randomized to  receive either  GMK or  observation with  no  treatment.    The
primary endpoint  of the  trial is  to compare  the recurrence  of melanoma in
patients receiving  GMK versus  in  patients  receiving  observation  with  no
treatment.   The study  will also compare overall survival of patients in both
groups.

     A predecessor of GMK, called GM2-BCG, which combined GM2 ganglioside with
the adjuvant  BCG, underwent  clinical testing  at Sloan-Kettering in the late
1980s.  In a double-blind, randomized Phase II study in 122 Stage III melanoma
patients, subjects  in the treated group received GM2-BCG for six months after
surgery; subjects  in the  control group  received the  same regimen  with BCG
alone.   The median recurrence-free survival period after surgery for patients
treated with  GM2-BCG was  33 months  versus 17 months for the patients in the
control group.  In addition,  the median overall survival period after surgery
for patients  in the treated group was 70 months versus 30 months for patients
in  the  control  group.  Approximately  85%  of  treated  patients  developed
antibodies to GM2 ganglioside.  The presence of these antibodies significantly
correlated with improved recurrence-free and overall survival of patients.


                                      7
<PAGE>
     Phase  I/II   clinical  trials   of  GMK  under  institutional  new  drug
applications ("INDs")  were conducted  at Sloan-Kettering.   In these studies,
approximately 120  patients, most of whom had Stage III melanoma, were treated
with GMK.   All  patients receiving  GMK at  the dose  level being used in the
current Phase III trials of GMK developed antibodies to GM2 ganglioside, which
killed melanoma  cells.   Patients treated  with GMK had levels of antibody to
GM2 ganglioside  that were  on average  four times higher and also were longer
lasting than  in patients  treated with GM2-BCG in the GM2-BCG Phase II trial.
In addition,  GMK was  well tolerated by all patients in these studies, and no
clinically significant side effects attributable to the vaccine were observed.

          MGV: Therapeutic Vaccine for Certain Cancers

     Progenics' second ganglioside conjugate vaccine in development, MGV, is a
proprietary  therapeutic   vaccine  for  cancers  which  express  GD2  or  GM2
gangliosides.   These cancers  include colorectal cancer, lymphoma, small cell
lung cancer,  sarcoma, gastric  cancer and  neuroblastoma.    The  Company  is
collaborating with BMS on this program.  MGV has three components: (i) GM2-KLH
(GM2 ganglioside  conjugated to KLH); (ii) GD2-KLH (GD2 ganglioside conjugated
to KLH);  and (iii)  QS-21 adjuvant.  MGV is designed to prevent recurrence of
cancer and  prolong overall  survival of  patients after their cancer has been
removed by surgery or reduced by chemotherapy or radiation therapy.

     Target Market

     MGV targets cancers that the American Cancer Society estimated would have
an aggregate  incidence in the United States of over 260,000 during 1998.  The
American Cancer  Society also  estimated that  over 135,000  persons would die
from these  targeted cancers,  representing nearly  25% of all expected deaths
from any cancer during 1998.

          Clinical Trials

     MGV completed  a Phase I/II clinical trial in 1998 under an institutional
IND at Sloan-Kettering.  The primary objectives of the study were to establish
the safety  of MGV  and the  ability of  the vaccine to induce specific immune
responses to  both GD2  and GM2 gangliosides in patients with different cancer
types.   In addition, a goal of the study was to optimize the ratio of GD2 and
GM2 gangliosides in MGV to be used in future clinical trials.

     In this  clinical trial,  31 patients with high-risk melanoma and sarcoma
were immunized  with MGV over a period of nine months.  Patients were randomly
assigned to  five groups  receiving a fixed dose of GM2-KLH and QS-21 adjuvant
and one  of a  number of  escalating doses of GD2-KLH.  This study showed that
the combination  of GM2-KLH/GD2-KLH/QS-21  could produce antibodies to GM2 and
GD2 and  was well-tolerated.   The Company and BMS intend to commence Phase II
clinical trials of MGV in 1999.

     HIV Therapeutics

     HIV infection  causes a  slowly progressive  deterioration of  the immune
system which  results in AIDS.  AIDS is characterized by a general collapse of
the immune  system leading  to  a  wasting  syndrome,  frequent  opportunistic
infections, rare  forms of  cancer, central  nervous system  degeneration  and
eventual death.  HIV infection is unusual in that individuals testing positive
for the  virus can  survive for  many years  without symptoms  of the disease.
There are  three major  routes of  transmission of  the virus: sexual contact,
exposure to  HIV-contaminated blood  or  blood  products  and  mother-to-child
transmission.

     HIV specifically  infects cells  that have  the  CD4  receptor  on  their
surface ("CD4+").  CD4+ cells are critical components of the immune system and
include T  lymphocytes, monocytes,  macrophages  and  dendritic  cells.    The
deleterious effects  of HIV are largely due to the replication of the virus in
these cells and the resulting dysfunction and destruction of these cells.


                                      8
<PAGE>
     HIV-positive individuals  display both antibodies and other immune system
responses which  are specific  to the  virus.  However, it is clear that these
natural immune  system responses do not provide adequate long-term protection.
There are  two reasons  why these natural responses are inadequate.  First, as
described above,  the CD4+ T lymphocytes required to mount an effective immune
response against  HIV are  destroyed, leaving  the immune  system too  weak to
eliminate the  virus.  Second, HIV displays a remarkable degree of variability
as a  result of  high rates  of mutation  that permit different strains of the
virus to  escape  the  immune  system  response  and  progressively  replicate
throughout the body.

     Viral infection  involves the  binding of the virus to cells, viral entry
into those  cells and,  ultimately,  the  commandeering  of  the  host  cells'
reproductive  machinery,  which  permits  replication  of  the  viral  genetic
information and  the generation  of new  copies of  the virus.   The Company's
scientists  and   their  collaborators  have  made  important  discoveries  in
understanding how  HIV enters human cells and initiates viral replication.  In
the 1980s,  Company scientists  in collaboration  with researchers at Columbia
University, the ICR and the Centers for Disease Control and Prevention ("CDC")
demonstrated that  the initial  step of  HIV infection  involves the  specific
attachment of  the virus  to the  CD4 receptor  on the surface of human immune
system cells.   These  researchers also  showed that  the  gp120  glycoprotein
located on  the HIV  envelope binds  with high  affinity to  the CD4 receptor.
Although these  researchers  demonstrated  that  CD4  was  necessary  for  HIV
attachment, this  step is not sufficient to enable the virus to enter the cell
and initiate viral replication.

     Company scientists in collaboration with researchers at the Aaron Diamond
AIDS Research Center ("ADARC") described in an article in Nature the discovery
of a  co-receptor for  HIV on  the surface of human immune system cells.  This
co-receptor, CCR5,  enables fusion of HIV with the cell membrane after binding
of the  virus to  the CD4  receptor.  This fusion step results in entry of the
viral genetic  information into  the cell  and subsequent  viral  replication.
Company scientists  in collaboration  with researchers  at ADARC  demonstrated
that it  is the  gp120 glycoprotein that binds to the CCR5 co-receptor as well
as to  the CD4  receptor.   By mutational analysis, these scientists localized
the gp120  binding site  on CCR5  to a  discrete region  at  one  end  of  the
molecule.

     In 1998,  a member  of the  Company's Scientific Advisory Board, Wayne A.
Hendrickson, Ph.D.,  reported a high-resolution x-ray crystal structure of the
gp120:CD4 complex.   The  Company believes  that this  structural  information
reveals several  important features of the gp120:CD4 complex and provides, for
the first  time, a  rational basis  for discovering  compounds that block this
interaction.

          Progenics' HIV Receptor Technologies

     Based on  the Company's  participation in  the discoveries  of two  major
receptors for  HIV, Progenics  is pursuing  several approaches in the research
and development  of products  designed to block entry of HIV into human immune
system cells.   The  Company's PRO  542 and PRO 367 product candidates and its
viral attachment  programs are  based on  the CD4  receptor while  its HIV co-
receptor fusion program is based on recently discovered co-receptors, CCR5 and
CXCR4.

     Because HIV  must first attach to the CD4 receptor to infect human cells,
the Company  believes that the part of the gp120 glycoprotein that attaches to
the CD4  receptor must  remain constant  across all strains of the virus.  The
gp120 glycoprotein  is located  on the  exterior of  both HIV and HIV-infected
cells. PRO  542 and  PRO 367  incorporate a  part of  the  CD4  receptor  into
genetically  engineered  molecules  that  function  like  antibodies  and  are
designed to bind specifically to the gp120 glycoprotein of HIV or HIV-infected
cells.   In in  vitro tests,  these molecules have demonstrated the ability to
bind with  high affinity  to gp120  glycoproteins from  a wide  range  of  HIV
strains, including  the strains  most prevalent  in the  United States and the
rest of  the world.  Because this technology is targeted to a part of HIV that
is believed  to be  necessary for  the virus to enter cells and not to mutate,
the Company  believes that  its technology may address the obstacles presented
by the high mutation rate of the virus.

     PRO 542 and PRO 367 employ this technology in different ways.  PRO 542 is
designed to  bind to  the gp120  glycoprotein located  on  the  virus  itself,
neutralizing the virus and thereby preventing it from infecting healthy cells.
PRO 367  is designed to bind to the gp120 glycoprotein located on the exterior
of HIV-infected  cells and  destroy those cells by delivering a lethal dose of
radiation.


                                      9
<PAGE>
     The Company  recently announced  the development of a panel of monoclonal
antibodies that  have been  shown to  block the ability of HIV to infect cells
isolated from  healthy individuals  by inhibiting  virus-cell fusion.   One of
these monoclonal  antibodies, designated  PRO 140,  inhibited  HIV  fusion  at
concentrations that had no apparent effect on the normal function of CCR5.

     Progenics also is applying its HIV technology in two programs designed to
use the  Company's  proprietary  screening  assays  to  identify  and  develop
potential HIV therapeutics.  In its co-receptor/fusion program, the Company is
using its  fusion assays  to identify  compounds that  inhibit the interaction
between HIV  and HIV  co-receptors, including CCR5 and CXCR4, thereby blocking
viral fusion  and entry. In the Company's HIV attachment program, Progenics is
using  its   proprietary  HIV  attachment  assay  to  identify  small-molecule
compounds that  inhibit the  interaction between HIV and CD4, thereby blocking
viral attachment.

          Target Market

     Progenics' therapeutic  product candidates are designed primarily for use
in asymptomatic  HIV-positive individuals.  Accordingly, the target population
for these products is patients who are aware of their infection but do not yet
have AIDS.   Although  there are  few signs  of  disease  in  an  HIV-positive
individual during  the asymptomatic  period, the  virus is  replicating in the
body by  infecting healthy  cells.   The  World  Health  Organization  ("WHO")
estimated that  as of the end of 1998, 1.4 million people in North America and
Western Europe  and 33.4  million people  worldwide were  infected  with  HIV.
According to  WHO, approximately  74,000 people  in North  America and Western
Europe were newly infected with HIV during 1998.

     Current Therapies

     At present, two classes of products have received marketing approval from
the U.S.  Food and  Drug Administration  (the "FDA")  for the treatment of HIV
infection and  AIDS: reverse transcriptase inhibitors and protease inhibitors.
Both types of drugs are inhibitors of viral enzymes and have shown efficacy in
reducing the  concentration of  HIV in  the blood  and prolonging asymptomatic
periods  in   HIV-positive  individuals,   especially  when   administered  in
combination.

     While combination  therapy slows  the progression of disease, it is not a
cure.   HIV's rapid  mutation rate results in the development of viral strains
that are  resistant to  reverse transcriptase  and protease  inhibitors.   The
potential for  resistance is exacerbated by interruptions in dosing which lead
to lower  drug levels  and permit increased viral replication.  Non-compliance
is common  in patients on combination therapies as these drug regimens require
more than  a dozen  tablets to  be  taken  at  specific  times  each  day.  An
additional problem  is  that  currently  approved  drugs  exhibit  substantial
toxicities in  many patients,  affecting a  variety  of  organs  and  tissues,
including the  peripheral nervous  system and  gastrointestinal tract.   These
toxicities often result in patients interrupting or discontinuing therapy.

          PRO 542: HIV Therapy

     Progenics is  developing PRO 542 for the treatment of HIV infection.  PRO
542 is  a proprietary  antibody-like product  with four  binding sites for the
gp120 glycoprotein  on HIV.  PRO 542 is designed to neutralize HIV through one
of  two  mechanisms:  (i)  binding  to  the  gp120  glycoprotein  and  thereby
preventing infection  of healthy  cells; or  (ii) binding to and detaching the
gp120 glycoprotein from the virus.

     In in  vitro and  ex vivo  tests conducted  by Progenics in collaboration
with scientists  at ADARC  and the  CDC, PRO 542 neutralized a wide variety of
clinical strains  of HIV  as well  as viruses  in the  plasma of  HIV-positive
individuals.   In comparative  in vitro  studies at  ADARC using  a  panel  of
neutralizing antibodies  to HIV,  PRO 542  was found  to be  more  potent  and
broadly neutralizing than the antibodies to which it was compared.  In further
studies at  ADARC, PRO 542 protected severe combined immune deficient ("SCID")
mice transplanted with human peripheral blood lymphocytes against infection by
the three  HIV strains  tested, including  strains of  the virus isolated from
HIV-positive individuals.


                                     10
<PAGE>
     Progenics initiated two dose-escalation Phase I/II clinical trials of PRO
542 in  September 1997.   Both  trials are  designed to  measure  the  safety,
pharmacokinetics, immunogenicity and antiviral activity of PRO 542.  The first
study was  conducted in  HIV-positive adult  patients at  Mount Sinai  Medical
Center in  New  York  City.    Findings  indicated  peak  and  one-week  serum
concentrations  of   PRO  542  compared  favorably  with  preclinical  models,
approximating drug  levels previously shown to neutralize clinical HIV strains
in vitro.   Data  from this trial indicate that PRO 542 was well-tolerated and
non-immunogenic in  all patients treated.  No significant drug-related adverse
events were observed at any dose level.  PRO 542 serum concentrations remained
above HIV  inhibitory levels  for greater  than one week. The Company believes
that these  results support  expanded clinical  testing of  this  agent  as  a
nontoxic therapy for HIV infection.

     The second  dose-escalation Phase I/II clinical trial of PRO 542 is being
conducted in  HIV-positive children  at Baylor College of Medicine in Houston,
the  University   of  California  at  San  Francisco  and  the  University  of
Pennsylvania  by   the  AIDS   Clinical  Trials  Group,  ("ACTG"),  a  leading
cooperative HIV  research group supported by the National Institute of Allergy
and Infectious Diseases ("NIAID").

     In September  1997, the  Company entered  into a  collaboration agreement
with Genzyme  Transgenics with the objective of developing a transgenic source
of  PRO   542  using   Genzyme  Transgenics'  proprietary  technology.    This
collaboration  is  designed  to  result  in  commercial-scale  manufacture  by
expressing PRO  542 in  the milk  of transgenic  goats.   By establishing this
production  arrangement,   Progenics  can   potentially  advance   PRO   542's
development  through  Phase  III  clinical  trials  without  the  need  for  a
commercialization collaboration.

          PRO 367: HIV Therapy

     Progenics is  developing PRO  367 as  a  therapeutic  agent  designed  to
destroy HIV-infected cells. PRO 367 is composed of a proprietary antibody-like
molecule with  two binding  sites for  the  gp120  glycoprotein  linked  to  a
therapeutic radioisotope.   PRO 367 is designed to specifically bind with high
affinity to  the gp120 glycoprotein on HIV-infected cells and to destroy these
cells by delivering a lethal dose of radiation.  The Company plans to initiate
dose-escalation Phase  I/II clinical  trials of  PRO 367  in 1999  subject  to
obtaining necessary  regulatory clearances.   The  study is expected to assess
safety,  pharmacokinetics,   biodistribution,  immunogenicity   and  antiviral
effects of PRO 367 in HIV-positive adult patients.

     In in  vitro tests,  PRO 367 specifically bound with high affinity to the
gp120 glycoprotein on the cell surface.  In addition, a pilot Phase I clinical
trial in  AIDS patients  of a trace-labeled precursor of PRO 367 was conducted
under an institutional IND at Sloan-Kettering.  This trial assessed the safety
and pharmacology  of the  compound with low doses of iodine-131.  The compound
was well  tolerated by  all patients,  no clinically  significant side effects
attributable to the compound were observed and the compound exhibited suitable
pharmacokinetics for further development.

          HIV Co-Receptor/Fusion: HIV Therapy

     The Company's  first application  of its  HIV co-receptor  technology  is
through the  use of  its proprietary fusion assays.  These assays model fusion
of HIV  with human  cells rapidly,  automatically, sensitively and without the
use of  infectious virus.   The  Company has entered into a collaboration with
Roche  to  use  these  assays  to  discover  and  develop  small-molecule  HIV
therapeutics that  target the  fusion coreceptors,  including CCR5  and CXCR4.
Under the  terms of  the collaboration,  Roche has  received from Progenics an
exclusive worldwide  license to  its HIV  co-receptor technology.    Roche  is
obligated to  make up-front  and milestone  payments, fund  research for up to
three years  and pay royalties on the sale of any products commercialized as a
result of the collaboration.


                                     11

     CCR5 and  CXCR4 belong to a larger family of cellular receptors, known as
7-transmembrane  G-protein-coupled  receptors.    These  receptors  have  been
successfully exploited  as  drug  targets  by  commercialized  pharmaceuticals
addressing a  wide range  of  human  diseases.    Additionally,  studies  have
indicated that  a genetic  mutation that  disables the  CCR5 co-receptor  will
prevent HIV  infection  without  compromising  immune  function.    For  these
reasons, the  Company believes  that its  co-receptor/fusion technology offers
significant commercial opportunities.

     The Company  recently announced  the development  of a panel of anti-CCR5
monoclonal antibodies created at Progenics and evaluated in collaboration with
ADARC.   These antibodies  blocked the ability of HIV to infect cells isolated
from healthy  individuals by  inhibiting virus-cell  fusion, an  approach  not
targeted by  current HIV  therapies.   One monoclonal antibody, designated PRO
140, inhibited HIV at concentrations that had no apparent effect on the normal
function of  CCR5.  These properties were correlated with PRO 140's ability to
bind to a distinct site on CCR5.

          HIV Attachment Drug Screen: HIV Therapy

     As part  of  a  collaborative  research  project  with  the  Wyeth-Ayerst
Research Division  of American Home Products Corporation ("AHP"), Progenics is
using  its   proprietary  HIV  attachment  assay  to  identify  small-molecule
compounds that  inhibit attachment of HIV to the CD4 receptor.  This assay has
been used in a high-throughput screening program, and the compounds discovered
are undergoing  additional studies  by the Company and AHP to evaluate further
their antiviral activity.

     In June  1998 the  Company entered into a collaboration with Pharmacopeia
to discover  small-molecule HIV  therapeutics that block the attachment of the
virus to  its primary cellular receptor, CD4.  Pursuant to this collaboration,
Progenics has  provided proprietary technologies for high-throughput screening
of compounds  that  inhibit  the  attachment  of  HIV  to  the  CD4  receptor.
Pharmacopeia has  contributed proprietary combinatorial chemistry libraries of
small-molecule drug candidates and medicinal chemistry expertise.

          ProVax: HIV Vaccine

     Progenics is  conducting research  with respect  to its ProVax vaccine, a
vaccine candidate  which it  believes may  be useful  as a  preventative or  a
therapeutic treatment  for HIV-positive  individuals.   Progenics is currently
performing government-funded research and development of the ProVax vaccine in
collaboration with  ADARC, the Southwest Foundation for Biomedical Research in
San Antonio and the University of Oklahoma Medical Center.

     Other Therapeutics - DHA

     In February  1999 Progenics  licensed from  Sloan-Kettering patent rights
and technology  relating to  dehydroascorbic acid  ("DHA"),  a  derivative  of
vitamin C.   Progenics has obtained exclusive world-wide rights to use DHA for
treatment of  disease involving  oxidative damage to tissue, including tissues
of the central nervous system.

     Antioxidants are  compounds that  act as  scavengers of  free radicals --
highly unstable  molecules that  play a  role in  certain diseases that damage
tissue.   Studies have  shown that  antioxidants can  slow the  progression of
degenerative   neurological diseases,  such as Alzheimer's disease.  Vitamin C
is a potent antioxidant, but does not easily cross from the circulatory system
into the  brain.    David  W.  Golde,  M.D.,  Physician-in-Chief  of  Memorial
Hospital, and  his colleagues  at Sloan-Kettering  have shown that DHA readily
crosses the  blood-brain barrier  and, once  in the  brain, is  converted into
vitamin C.   As a result of these properties, the Company believes that DHA is
a promising  drug candidate  for a  broad range  of neurodegenerative diseases
caused by  oxidative stress.    The  Company  has  initiated  a  research  and
development program to pursue these applications.

     Assays and Reagents

     Through its immunology expertise, Progenics has developed certain assays,
in addition  to its  HIV attachment  and fusion  assays, which  are used  both
independently and  in collaboration with partners, as well as certain reagents
which are being sold for research use only.  These assays are described below.

          ONCOTECT GM

     Progenics has  developed ONCOTECT  GM, a  clinical  assay  for  assessing
prognosis in  patients with  melanoma and other cancers.  ONCOTECT GM measures
the levels of antibody to GM2 ganglioside in the blood.  In clinical trials of
a  therapeutic   vaccine  for  melanoma,  the  presence  of  these  antibodies
significantly correlated with improved recurrence-free and overall survival of
patients.   The Company  is currently  using ONCOTECT GM in its cancer vaccine
clinical trials.

          Research Reagents: sCD4 and gp120

     Progenics manufactures  the research  reagents sCD4  and gp120  which  it
sells to  DuPont de  Nemours &  Company ("DuPont")  and  Intracel  Corporation
("Intracel") for  resale.   DuPont markets and sells gp120 and sCD4 under both
the Progenics and the DuPont names.  Intracel markets and sells gp120 and sCD4
under both  the Progenics  and  Intracel  names.    These  products  are  sold
worldwide for research use.

     Corporate Collaborations

          Bristol-Myers Squibb Company

     In July 1997, the Company and BMS entered into the BMS License Agreement.
Pursuant to  the  BMS  License  Agreement,  the  Company  granted  to  BMS  an
exclusive, worldwide  license to  make, have  made, use,  sell, have  sold and
develop GMK  and MGV  and any other product to which Progenics has rights that
include the  GM2 or GD2 ganglioside antigens and are used for the treatment or
prevention of  human cancer.   BMS is entitled under the BMS License Agreement
to grant sublicenses, subject to certain restrictions.

     Pursuant  to  the  BMS  License  Agreement  and  the  related  sublicense
agreements (collectively, the "BMS Agreements"), BMS has made certain payments
to the Company and is required to make milestone payments and pay royalties on
sales of  licensed products.  In July 1997, BMS paid the Company approximately
$13.3 million,  representing (i)  $11.5 million  as reimbursement for expenses
previously incurred  by Progenics  in the  development  of  GMK  and  MGV  and
licensing fees  and (ii)  $1.8  million  as  reimbursement  of  the  Company's
clinical development costs for the period from April 15, 1997 to September 30,
1997.   BMS is  also required  to make  payments of  up to  $61.5 million upon
achievement of specified milestones relating to the development and regulatory
approval of GMK, MGV or other products that include the GM2 or GD2 ganglioside
antigens.   In June 1998, the Company announced that it had received the first
such payment  for achieving  a clinical  milestone in  the development of GMK.
The amount  of these  milestone payments  will depend on the product candidate
achieving the  specified milestone  and, with  respect to MGV, the indications
for which  it is developed.  BMS is also required to pay royalties on any sale
of licensed products and to subsidize ongoing development, clinical trials and
regulatory activities  of GMK  and MGV  pursuant to  plans agreed  to  by  the
parties. There  can be  no assurance  that the Company will receive additional
milestone or  royalty payments  from BMS  or that  funding for  the GMK or MGV
programs will not be curtailed or terminated.

     In connection  with the BMS License Agreement, the Company granted to BMS
sublicenses to  the technology  and other  rights licensed to the Company from
each of  Sloan-Kettering, The  Regents of  the University  of California  (the
"Regents") and  Aquila under  the licenses with these entities discussed under
"--Licenses."   These sublicenses  are exclusive as to the Sloan-Kettering and
the Regents  sublicenses and non-exclusive as to the Aquila sublicense and are
intended, in  general, to make available to BMS the technology licensed by the
Company from  these entities  and used  to make  GMK and MGV.  BMS is entitled
under these  sublicenses to  grant further  sublicenses,  subject  to  certain
restrictions.

     In connection  with payments  made by  BMS to  the Company  under the BMS
Agreements, the Company made certain payments to licensors as an inducement to
these licensors  to enter  into agreements  with the  Company and BMS amending
certain provisions  of the  prime licenses and granting to BMS certain related
rights.   Future payments  made by BMS to the Company under the BMS Agreements
also trigger payment obligations to these licensors.  See "--Licenses."


                                     13
<PAGE>
     The BMS Agreements terminate at various times related, in general, to the
expiration or  abandonment of  the related  patents or to the first commercial
sale of  products.  The agreements can also be terminated by either party upon
a material,  uncured breach  by the other party.  BMS has the further right to
terminate the  BMS License  Agreement (including  its  funding  and  milestone
obligations) as to specified licensed products at specified times.

          Roche Group

     In December 1997, the Company entered into a collaboration agreement with
Roche to  discover and develop novel HIV therapeutics that target the recently
identified fusion  co-receptors of  the virus  (the "Roche  Agreement").  This
collaboration, among  other things, provides for Roche to apply its library of
small-molecule compounds  to original  screening  assays  of  the  Company  to
identify inhibitors of the interaction between HIV co-receptors and HIV.

     Under the  terms of the Roche Agreement, Progenics has granted to Roche a
license covering  products to which Progenics has rights or that are developed
as a  result of  the collaboration  and which  have  been  identified  as,  or
developed for  the purpose  of, inhibiting  the interaction  between chemokine
receptors that  act as  HIV co-receptors,  including CCR5  and CXCR4, and HIV,
which interaction  results in  fusion of HIV with cells.  The license does not
extend to  certain classes  of molecules,  as to  which Progenics has retained
rights.   Pursuant to  this license, Roche has an exclusive worldwide right to
develop, make,  have made,  use, sell,  offer to  sell and  import any covered
products for  the therapy  of HIV infection.  Subject to certain restrictions,
Roche retains the right to grant sublicenses under the Roche Agreement.

     Pursuant to  the Roche Agreement, Roche is obligated to make up-front and
milestone payments,  fund research  for up to three years and pay royalties on
the sale of any products commercialized as a result of the collaboration.  The
Company is  also entitled  to certain  contingent licensing  rights.   In June
1998, the  Company announced  that it  had received the first such payment for
achieving a milestone in its HIV drug discovery program.

     The collaboration  remains in  full  force,  subject  to  the  exceptions
identified below,  until the  expiration of  all obligations  to pay royalties
pursuant to  any of  the licenses granted therein.  The Roche Agreement can be
terminated by either party upon a material, uncured breach by the other party.
Roche  has  the  further  right  to  terminate  the  Roche  Agreement  or  the
collaboration contemplated  under the  Roche  Agreement  at  specified  times;
however, in  either case,  Roche will  not  be  relieved  of  certain  minimum
research funding obligations.

     This collaboration  is in  the early stage of drug discovery.   There can
be no  assurance that  the Company  will receive  additional milestone  or any
royalty payments  from Roche, that funding for the program contemplated by the
collaboration will  not be  curtailed or  terminated or  that  any  contingent
licensing rights will be granted.

     Licenses

     The Company  is a  party to  license  arrangements  under  which  it  has
obtained rights to use certain technologies in its cancer and HIV programs, as
well as  certain other  human therapeutics.   Set  forth below is a summary of
these licenses.


                                     14
<PAGE>
     The Company  is party  to a  license agreement with Sloan-Kettering under
which  the  Company  obtained  the  worldwide,  exclusive  rights  to  certain
technology relating  to ganglioside conjugate vaccines, including GMK and MGV,
and their  use to  treat or  prevent  cancer.    The  Sloan-Kettering  license
terminates upon the expiration of the last of the licensed patents or 15 years
from the  date of  the first commercial sale of a licensed product pursuant to
the agreement,  whichever is  later.   In addition to patent applications, the
Sloan-Kettering license  includes the exclusive rights to use certain relevant
technical  information   and  know-how.      A   number   of   Sloan-Kettering
physician-scientists also serve as consultants to the Company.

     The Company  is party to a license agreement with the Regents under which
the Company  obtained the  exclusive rights  to an issued U.S. patent covering
certain ganglioside conjugate vaccines.  The license agreement terminates upon
the expiration of the patent.

     The Company  is party  to a  license agreement  with Columbia  University
under which  the Company  has obtained  exclusive, worldwide rights to certain
technology and  materials relating  to CD4 and its use to treat or prevent HIV
infection.   The license  agreement will  terminate upon the expiration of the
last of the licensed patents.

     The Company  has entered  into a license and supply agreement with Aquila
pursuant to  which Aquila  agreed to  supply  the  Company  with  all  of  its
requirements for  the QS-21  adjuvant for  use  in  certain  ganglioside-based
cancer vaccines,  including GMK  and MGV.   QS-21  is the lead compound in the
Stimulon_ family  of adjuvants  developed and  owned by  Aquila.   The license
terminates upon the expiration of the last of the licensed patents.

     The Company  is a party to a license agreement with Sloan-Kettering under
which the  Company obtained  an exclusive, worldwide license to certain patent
rights relating  to DHA.   The license continues for 20 years or to the end of
the term for which the patent rights are granted.

     The licenses  to which  the Company  is a party impose various milestone,
commercialization,  sublicensing,   royalty  and   other  payment,  insurance,
indemnification and  other obligations  on the  Company  and  are  subject  to
certain reservations  of rights.   Failure by the Company to comply with these
requirements could  result in  the termination  of the  applicable  agreement,
which could have a material adverse effect on the Company.

     In connection  with the BMS License Agreement, the Company granted to BMS
sublicenses to  the technology  and other  rights licensed to the Company from
each of  Sloan-Kettering, the Regents and Aquila under the licenses with these
entities  described  above.    See  "-Corporate  Collaborations--Bristol-Myers
Squibb Company."

     Government Grants And Contracts

     Through December 31, 1998, the Company had been awarded government grants
aggregating approximately  $5,407,000  under  the  Small  Business  Innovation
Research ("SBIR")  program of the NIH for the Company's commercial development
of PRO  542, PRO  367, ProVax  vaccine and fusion assays. Through December 31,
1998 the  Company had  recognized approximately  $3,386,000 of  such amount as
revenue.   In the  third quarter  of 1998, the Company was awarded a new grant
for $2.7  million from  the NIH  for the continued development of PRO 542.  In
addition, during  1995, the  Company was  awarded a  $812,000 multi-year grant
under a  contract with  the Department  of Defense for work related to Pro Vax
vaccine.  Work under this contract was completed in May 1998.

     In general,  under the  terms of these grants the Company has, subject to
certain rights  of the  government  described  below,  all  right,  title  and
interest to  all patents,  copyrights  and  data  pertaining  to  any  product
developed.   However, under  existing regulations,  the government  receives a
royalty-free license  for federal  government  use  with  respect  to  patents
developed by  grant recipients.   In  addition, the government may, in certain
circumstances, require  the Company  to license  technology resulting from the
funded projects  to third parties and may require that the Company manufacture
substantially all  of the  products resulting  from a  particular grant in the
United States.


                                     15
<PAGE>
     The government's  obligation to  make  payments  under  these  grants  is
subject to  appropriation by  the United  States Congress  for funding in each
such year.   Moreover, it is possible that Congress or the government agencies
that administer  these government  research programs  will determine  to scale
back these programs or terminate them or that the government will award future
grants to  competitors of  the Company  instead of  the Company.  In addition,
while Progenics  intends to pursue additional government grants related to its
areas of research and development, there can be no assurances that the Company
will be  awarded any  such grants  in the  future or  that any amounts derived
therefrom will not be less than those received to date.

     In  September   1997,  the   Company  was  awarded  a  two-year,  protein
manufacturing contract from the NIH; this contract was subsequently amended to
provide for  a total  term of three years at $2,426,870.  Through December 31,
1998, the  Company had  recognized approximately  $955,000 of  such amount  as
revenue.

     Patents and Proprietary Technology

     Progenics' policy  is to  protect its  proprietary  technology,  and  the
Company considers  the protection  of such  rights  to  be  important  to  its
business.   In addition  to seeking  U.S. patent  protection for  many of  its
inventions, the  Company generally files patent applications in Canada, Japan,
Western European  countries and  additional foreign  countries on  a selective
basis in  order to  protect the  inventions deemed  to  be  important  to  the
development of its foreign business.

     Under  a  license  agreement  with  Sloan-Kettering,  Progenics  obtained
worldwide, exclusive  rights to  certain technology  relating  to  ganglioside
conjugate vaccines,  including GMK  and MGV, and their use to treat or prevent
cancer.   This technology  is the  subject of  a patent  application filed  by
Sloan-Kettering in  the U.S.  and 25 foreign countries claiming composition of
matter and  methods of  production and  use of  certain ganglioside  conjugate
vaccines for the treatment or prevention of human cancer.

     Under a  license agreement  with Columbia  University, Progenics obtained
worldwide, exclusive  rights to certain technology relating to CD4 and its use
to treat  or prevent  HIV infection.  This technology is the subject of issued
U.S. and  European  patents  and  several  related  U.S.  and  foreign  patent
applications filed  by Columbia University.  The issued patents and the patent
applications claim  composition of matter and methods of production and use of
certain CD4-based  products for  the treatment or prevention of HIV infection.
Progenics has  also filed  a number of U.S. and foreign patent applications on
its HIV  attachment assay  technology, its  technology relating to PRO 542 and
PRO 367,  its PROVax  technology and  clinical  uses  of  these  technologies.
Progenics has also filed a number of U.S. and foreign patent applications (one
of which  is owned  jointly with  ADARC) relating  to the  discovery of an HIV
co-receptor, CCR5.

     Under  a   License  Agreement  with  Sloan-Kettering,  Progenics obtained
worldwide, exclusive  rights to certain technology relating to dehydroascorbic
acid and  its use  to increase  the concentration  of  vitamin  C  in tissues,
including the brain for treating neurodegenerative and neurovascular diseases.
This  technology  is  the  subject  of a patent  application  filed by  Sloan-
Kettering in the  United States  and as an  international application claiming
methods for increasing the vitamin C  concentration  in the cells of a subject
by administering to the subject dehydroascorbic acid.

     The enactment  of the  legislation implementing  the General Agreement on
Tariffs and Trade has resulted in certain changes to United States patent laws
that became  effective on  June 8,  1995.   Most notably,  the term  of patent
protection for patent applications filed on or after June 8, 1995 is no longer
a period  of seventeen  years from  the date of grant.  The new term of United
States patents  will commence  on the  date of  issuance and  terminate twenty
years from the earliest effective filing date of the application.  Because the
time from  filing to  issuance of patent applications is often more than three
years, a  twenty-year term  from the  effective date of filing may result in a
substantially shortened  term of patent protection, which may adversely impact
the Company's patent position.


                                     16
<PAGE>
     Government Regulation

     The Company  and its  products are subject to comprehensive regulation by
the FDA in the United States and by comparable authorities in other countries.
These national agencies and other federal, state, and local entities regulate,
among  other   things,  the   preclinical  and   clinical   testing,   safety,
effectiveness, approval,  manufacture, labeling,  marketing, export,  storage,
record keeping, advertising, and promotion of the Company's products.  None of
the Company's  product candidates  have received  marketing or  other approval
from the FDA or any other similar regulatory authority.

     FDA approval  of the  Company's  products,  including  a  review  of  the
manufacturing processes  and facilities used to produce such products, will be
required before  such products  may be  marketed in  the United  States.   The
process of  obtaining approvals from the FDA can be costly, time consuming and
subject to  unanticipated delays.  There can be no assurance that approvals of
the Company's proposed products, processes, or facilities will be granted on a
timely basis,  or at  all.   Any failure  to obtain or delay in obtaining such
approvals would  adversely affect  the ability  of the  Company to  market its
proposed products.  Moreover, even  if regulatory  approval is  granted,  such
approval may  include significant  limitations on  indicated uses  for which a
product could be marketed.

     The process  required by  the FDA  before the  Company's products  may be
approved for marketing in the United States generally involves (i) preclinical
laboratory and  animal tests, (ii) submission to the FDA of an IND, which must
become  effective  before  clinical  trials  may  begin,  (iii)  adequate  and
well-controlled human  clinical trials to establish the safety and efficacy of
the product  for its  intended indication,  (iv) submission  to the  FDA of  a
marketing application and (v) FDA review of the marketing application in order
to determine,  among other  things, whether  the product is safe and effective
for its intended uses.

     Preclinical tests  include laboratory evaluation of product chemistry and
animal studies  to gain preliminary information about a product's pharmacology
and toxicology and to identify any safety problems that would preclude testing
in humans.   Products must generally be manufactured according to current Good
Manufacturing  Practices  ("cGMP"),  and  preclinical  safety  tests  must  be
conducted by  laboratories that  comply with  FDA regulations  regarding  good
laboratory practices.   The  results of the preclinical tests are submitted to
the FDA  as part  of an  IND.   An IND  is a submission which the sponsor of a
clinical trial  of an  investigational new drug must make to the FDA and which
must become effective before clinical trials may commence.  The IND submission
must  include,   among  other   things,  a   description  of   the   sponsor's
investigational  plan;   protocols  for   each   planned   study;   chemistry,
manufacturing,  and   control   information;   pharmacology   and   toxicology
information;  and   a  summary   of  previous   human  experience   with   the
investigational drug.   Unless the FDA objects to, or makes comments or raises
questions concerning,  an IND, the IND will become effective 30 days following
its receipt  by the  FDA, and  initial clinical  studies may  begin,  although
companies often obtain affirmative FDA approval before beginning such studies.
There can  be no  assurance that  submission of  an IND  will  result  in  FDA
authorization to commence clinical trials.

     A New  Drug Application  ("NDA") is an application to the FDA to market a
new drug.  The NDA must contain, among other things, information on chemistry,
manufacturing, and  controls; nonclinical  pharmacology and  toxicology; human
pharmacokinetics and bioavailability; and clinical data.  The new drug may not
be marketed in the United States until the FDA has approved the NDA.

     A Biologic  License Application  ("BLA") is  an application to the FDA to
market a  biological product.   The PLA must contain, among other things, data
derived from  nonclinical laboratory  and clinical  studies which  demonstrate
that the product meets prescribed standards of safety, purity and potency, and
a full  description of  manufacturing methods.  The biological product may not
be marketed in the United States until a biologic license is issued.

     Clinical trials  involve the  administration of  the investigational  new
drug to healthy volunteers or to patients under the supervision of a qualified
principal investigator.  Clinical trials  must be conducted in accordance with
the FDA's  Good Clinical  Practice requirements  under protocols  that detail,
among other  things, the objectives of the study, the parameters to be used to
monitor safety,  and the effectiveness criteria to be evaluated. Each protocol
must be  submitted to the FDA as part of the IND. Further, each clinical study
must be conducted under the auspices of an Institutional Review Board ("IRB").
The IRB  will consider,  among other  things, ethical  factors, the  safety of
human subjects,  the possible  liability of  the institution  and the informed
consent disclosure which must be made to participants in the clinical trial.


                                     17
<PAGE>
     Clinical trials  are typically  conducted  in  three  sequential  phases,
although the  phases may  overlap.  During Phase I, when the drug is initially
administered to  human subjects,  the product  is tested  for  safety,  dosage
tolerance, absorption,  metabolism, distribution  and  excretion.    Phase  II
involves studies in a limited patient population to (i) evaluate preliminarily
the efficacy of the product for specific, targeted indications, (ii) determine
dosage tolerance  and optimal  dosage  and  (iii)  identify  possible  adverse
effects and  safety risks.   When a new product is found to have an effect and
to have  an acceptable safety profile in Phase II evaluation, Phase III trials
are undertaken  in order  to further evaluate clinical efficacy and to further
test for  safety within  an expanded  patient population.  The FDA may suspend
clinical trials  at any  point in  this process  if it concludes that clinical
subjects are being exposed to an unacceptable health risk.

     The  results  of  the  preclinical  studies  and  clinical  studies,  the
chemistry and  manufacturing data,  and the  proposed  labeling,  among  other
things, are  submitted to  the FDA  in the  form of an NDA or BLA, approval of
which must be obtained prior to commencement of commercial sales.  The FDA may
refuse to  accept the  NDA or  BLA for  filing if  certain administrative  and
content criteria  are not  satisfied, and  even after accepting the NDA or BLA
for review,  the FDA  may require  additional testing  or  information  before
approval of  the NDA  or BLA.   The  Company's analysis  of the results of its
clinical studies is subject to review and interpretation by the FDA, which may
differ from  the Company's  analysis. There  can  be  no  assurance  that  the
Company's data  or its interpretation of data will be accepted by the FDA.  In
any event,  the  FDA  must  deny  an  NDA  or  BLA  if  applicable  regulatory
requirements are  not ultimately satisfied.  In addition, delays or rejections
may be  encountered based  upon changes in applicable law or FDA policy during
the period  of product  development and  FDA regulatory  review.  Moreover, if
regulatory approval of a product is granted, such approval may be made subject
to various  conditions, including  post-marketing testing  and surveillance to
monitor the  safety of the product, or may entail limitations on the indicated
uses for  which it  may be  marketed.    Finally,  product  approvals  may  be
withdrawn if  compliance with  regulatory standards  is not  maintained or  if
problems occur following initial marketing.

     Both before  and after approval is obtained, a product, its manufacturer,
and the  sponsor of  the marketing  application for the product are subject to
comprehensive regulatory  oversight.  Violations of regulatory requirements at
any stage,  including  the  preclinical  and  clinical  testing  process,  the
approval process,  or thereafter  (including after  approval)  may  result  in
various adverse  consequences, including  FDA delay in approving or refusal to
approve a  product, withdrawal  of an  approved product from the market and/or
the imposition  of criminal penalties against the manufacturer and/or sponsor.
In addition,  later discovery  of previously  unknown problems  may result  in
restrictions on  such product,  manufacturer, or sponsor, including withdrawal
of the  product from  the market.   Also,  new government  requirements may be
established that  could delay  or prevent regulatory approval of the Company's
products under development.

     Whether  or   not  FDA   approval  has   been  obtained,  approval  of  a
pharmaceutical product  by comparable  government  regulatory  authorities  in
foreign countries  must be  obtained prior  to marketing  such product in such
countries.   The approval  procedure varies  from country  to country, and the
time required  may be  longer or  shorter than that required for FDA approval.
Although there  are some  procedures for  unified filing  for certain European
countries, in  general, each  country has its own procedures and requirements.
The Company does not currently have any facilities or personnel outside of the
United States.

     In addition  to regulations  enforced by  the FDA,  the Company  also  is
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  and various other present and potential future
federal, state  or local  regulations.  The Company's research and development
involves the  controlled use  of hazardous  materials, chemicals,  viruses and
various radioactive  compounds.  Although the Company believes that its safety
procedures for storing, handling, using and disposing of such materials comply
with  the   standards  prescribed  by  applicable  regulations,  the  risk  of
accidental contaminations  or injury from these materials cannot be completely
eliminated.   In the  event of  such an  accident, the  Company could  be held
liable for  any damages  that result  and any  such  liability  could  have  a
material adverse effect on the Company.

     Manufacturing

     The Company currently manufactures GMK, MGV, PRO 542, PRO 367 and PRO 140
in its  two pilot  production facilities in Tarrytown, New York.  One of these
facilities is  for the  production of  vaccines  and  the  other  is  for  the
production of  recombinant proteins.   The  Company believes that its existing
production facilities  will be  sufficient to meet the Company's initial needs
for clinical trials.  However, these facilities may be insufficient for all of
the  Company's   late-stage  clinical  trials  and  for  its  commercial-scale
requirements.   Accordingly, the  Company expects to be required in the future
to expand  its manufacturing staff and facilities and obtain new facilities or
to contract  with third  parties or its corporate collaborators to assist with
production.  Pursuant to the BMS License Agreement, the Company granted to BMS
manufacturing rights  with respect  to GMK  and MGV.  In the event the Company
decides to  establish a  full-scale  commercial  manufacturing  facility,  the
Company will require substantial additional funds and will be required to hire
and train  significant numbers of employees and comply with the extensive cGMP
regulations applicable to such a facility.

     Sales and Marketing

     Progenics plans  to market  products  for  which  it  obtains  regulatory
approval  through   co-marketing,  co-promotion,  licensing  and  distribution
arrangements with  third party  collaborators.  The Company believes that this
approach will  both increase  market penetration  and commercial acceptance of
its products  and enable  the Company  to avoid expending significant funds to
develop  a  large  sales  and  marketing  organization.    Pursuant  to  their
collaboration, the Company granted to BMS exclusive worldwide marketing rights
to GMK  and MGV.   The  Company also  has granted to Roche exclusive worldwide
marketing rights to products resulting from their collaboration.  In addition,
the Company  has entered into collaborative marketing arrangements with DuPont
and Intracel with respect to the sCD4 and gp120 research reagents.

     Competition

     Competition  in   the   biopharmaceutical   industry   is   intense   and
characterized by  ongoing research  and development  and technological change.
The Company  faces competition  from many companies and major universities and
research institutions  in the United States and abroad.  The Company will face
competition from  companies marketing  existing  products  or  developing  new
products for  diseases targeted  by the  Company's technologies.   Many of the
Company's competitors  have substantially  greater  resources,  experience  in
conducting preclinical  studies and  clinical trials  and obtaining regulatory
approvals for  their products,  operating experience, research and development
and marketing  capabilities and  production capabilities  than  those  of  the
Company.  There can be no assurance that the products under development by the
Company and  its collaborators  will be  able  to  compete  successfully  with
existing  products   or  products   under  development   by  other  companies,
universities and other institutions.  The Company's competitors may succeed in
obtaining FDA  approval for  products more  rapidly than  the Company.    Drug
manufacturers that  are first  in the market with a therapeutic for a specific
indication generally  obtain and  maintain a significant competitive advantage
over later  entrants.  Accordingly, the speed with which Progenics can develop
products, complete  the clinical  trials and approval processes and ultimately
supply commercial  quantities of  the products to the market is expected to be
an important competitive factor.

     With respect  to GMK,  the FDA  and certain  other regulatory authorities
have approved  high-dose alpha  interferon for  marketing as  a treatment  for
patients with  high risk melanoma. High-dose alpha interferon has demonstrated
some efficacy for this indication.  With respect to the Company's products for
the treatment of HIV infection, two classes of products made by competitors of
the Company  have been  approved for marketing by the FDA for the treatment of
HIV  infection   and  AIDS:  reverse  transcriptase  inhibitors  and  protease
inhibitors.   Both  types  of  drugs  have  shown  efficacy  in  reducing  the
concentration of  HIV in the blood and prolonging asymptomatic periods in HIV-
positive individuals, especially when administered in combination.


                                      19

     A significant  amount of  research in the biopharmaceutical field is also
being carried  out at  academic and  government institutions.   The  Company's
strategy is  to in-license technology and product candidates from academic and
government  institutions.     These  institutions  are  becoming  increasingly
sensitive to  the commercial  value of  their findings  and are  becoming more
aggressive  in   pursuing  patent   protection   and   negotiating   licensing
arrangements to  collect royalties  for  use  of  technology  that  they  have
developed.  These institutions may also market competitive commercial products
on their  own or  in collaboration  with competitors and will compete with the
Company in  recruiting highly  qualified scientific  personnel.  Any resulting
increase in  the cost or decrease in the availability of technology or product
candidates from these institutions may affect the Company's business strategy.

     Competition with  respect  to  the  Company's  technologies  and  product
candidates is and will be based, among other things, on effectiveness, safety,
reliability,  availability,   price  and   patent  position.    The  Company's
competitive position  will also  depend upon its ability to attract and retain
qualified  personnel,   to  obtain  patent  protection  or  otherwise  develop
proprietary products  or processes, and to secure sufficient capital resources
for  the   often  substantial  period  between  technological  conception  and
commercial sales.

     Product Liability

     The testing,  manufacturing  and  marketing  of  the  Company's  products
involves an  inherent risk  of product  liability attributable to unwanted and
potentially serious health effects.  To the extent the Company elects to test,
manufacture or market products independently, it will bear the risk of product
liability directly.  Pursuant to the BMS License Agreement, BMS is required to
indemnify the Company for liabilities and expenses resulting from, among other
things, the  manufacture, use  or sale of Licensed Products (as defined in the
BMS License  Agreement), subject  to certain  conditions.    The  Company  has
obtained insurance  in the  amount of  $5,000,000 against  the risk of product
liability.   This insurance  is subject  to certain  deductibles and  coverage
limitations.   There is  no guarantee  that  insurance  will  continue  to  be
available at  a reasonable  cost, or  at all,  or  that  the  amount  of  such
insurance will be adequate.

     Human Resources

     At February  28, 1999,  the Company  had 40  full-time employees, four of
whom (including  Dr. Maddon) hold Ph.D. degrees or foreign equivalents and two
of whom  (including Dr. Maddon) hold M.D. degrees.  At such date, 32 employees
were engaged  in research  and development, medical and regulatory affairs and
manufacturing activities and eight were engaged in finance, administration and
business development.   The Company considers its relations with its employees
to be  good.   None of  its employees  is covered  by a  collective bargaining
agreement.

     An  important   component  of   Progenics'  scientific  strategy  is  its
collaborative relationship  with leading  researchers in  cancer and virology.
Certain of  these researchers  are members  of the  Company's  two  Scientific
Advisory Boards  (each an  "SAB"), one  in cancer  and one  in virology.   The
members of  each SAB  attend periodic  meetings  and  provide  Progenics  with
specific expertise  in both  research and  clinical development.  In addition,
Progenics has collaborative research relationships with certain individual SAB
members.   All members  of the  SABs are  employed by employers other than the
Company and  may have commitments to or consulting or advisory agreements with
other entities  that may  limit their  availability to  the  Company.    These
companies may  also be  competitors of Progenics.  Several members of the SABs
have, from time to time, devoted significant time and energy to the affairs of
the Company.   However,  no member is regularly expected to devote more than a
small portion  of his  time to  Progenics.   In general, Progenics' scientific
advisors are  granted stock  options in  the  Company  and  receive  financial
remuneration for their services.

   RISK FACTORS

     The Company's  business and  operations entail  a variety  of  risks  and
uncertainties, including those described below.

Early Stage of Product Development; Technological Uncertainties

     The Company  is at  an early  stage of  development, and  the  successful
commercialization of  any products  will require significant further research,
development, testing  and/or regulatory  approvals and  additional investment.
Substantially  all   of  the  Company's  resources  have  been,  and  for  the
foreseeable future  are expected  to  be,  dedicated  to  the  development  of
products for diseases, most of which products are still in the early stages of
development and  testing.  There are a number of technological challenges that
the Company  must successfully  address to  complete most  of its  development
efforts.   In addition,  the product  development programs  conducted  by  the
Company and  its collaborators are subject to the risks of failure inherent in
the development  of product candidates based on new technologies.  These risks
include the  possibility that  the technologies used by the Company will prove
to be ineffective or any or all of the Company's product candidates will prove
to be unsafe or otherwise fail to receive necessary regulatory approvals; that
the  product   candidates,  if  safe  and  effective,  will  be  difficult  to
manufacture on  a large  scale or uneconomical to market; that the proprietary
rights of  third parties  will preclude  the Company or its collaborators from
marketing the  products utilizing  the Company's  technologies; or  that third
parties will  market equivalent  or  superior  products.    To  the  Company's
knowledge, no  cancer therapeutic  vaccine and  no drug  designed to treat HIV
infection by  blocking viral  entry has  been approved  for  marketing.    The
Company's other  research and development programs involve novel approaches to
human therapeutics.   There  can be  no assurance  that any  of the  Company's
products will  be successfully  developed.   The  commercial  success  of  the
Company's products,  if any,  when and  if approved  for marketing by the FDA,
will depend  upon their  acceptance by  the medical  community and third party
payors as  clinically useful,  cost effective  and safe.   Even  if any of the
Company's products  obtain regulatory approval, there can be no assurance that
any such product will achieve market acceptance of any significance.

     Uncertainty Associated with Preclinical and Clinical Testing

     Prior to  the commercial sale of any of the Company's potential products,
the Company  and/or  its  collaborators  must  demonstrate  their  safety  and
efficacy in  humans through  extensive preclinical  and clinical testing.  The
results of  preclinical studies by the Company and/or its collaborators may be
inconclusive and  may not  be indicative  of results  that will be obtained in
human clinical  trials.   There can  be no assurance that any of the Company's
products in  the research  or preclinical development stage will yield results
that would  permit or  justify clinical  testing.   Further, there  can be  no
assurance that  any of  the Company's potential products that undergo clinical
trials will  have the desired effect or will not have undesirable side effects
or other  characteristics that  may prevent  them from being approved or limit
their commercial  use if  approved.   In addition,  results attained  in early
human clinical  trials relating  to products  under development by the Company
may not  be indicative  of results  that will  be obtained  in later  clinical
trials. As  results of  particular preclinical studies and clinical trials are
received, the Company and/or its collaborators may abandon projects which they
might previously have believed to be promising, some of which may be described
herein.   In addition,  the Company,  its collaborators  or the  FDA or  other
regulatory agencies  may suspend  or terminate  clinical trials at any time if
the subjects  or patients  participating in  such trials  are being exposed to
unacceptable health risks.  Clinical testing is very expensive and can involve
many years.   The failure to adequately demonstrate the safety and efficacy of
a  therapeutic   product  under   development  by   the  Company   and/or  its
collaborators could  delay or  prevent regulatory  approval of the product and
would have a material adverse effect on the Company.

     The Company has commenced two Phase III clinical trials for GMK and plans
to commence  a third  such trial  in 1999.  If the results of these trails are
not satisfactory, the Company would need to conduct additional clinical trials
or abandon  its GMK  program.   Any such  result would have a material adverse
effect on the Company.

     Although for  planning purposes  the Company  forecasts the commencement,
continuation and  completion of  clinical  trials,  actual  results  can  vary
dramatically  due  to  factors  such  as  delays,  scheduling  conflicts  with
participating clinicians  and clinical  institutions and  the rate  of patient
accruals.   The Company's  most advanced  product candidates  are intended for
treating patients with relatively early stage cancer and are designed to delay
or prevent recurrence of disease.  As a consequence, clinical trials involving
these product  candidates are  likely to take longer to complete than clinical
trials involving  other types of therapeutics.  There can be no assurance that
clinical trials involving the Company's product candidates will commence or be
completed as forecasted.

     The Company  has limited  experience in  conducting clinical  trials.  In
certain circumstances  the Company relies on corporate collaborators, academic
institutions or  clinical research  organizations to conduct, supervise and/or
monitor some  or all  aspects  of  clinical  trials  involving  the  Company's
products.   In addition,  certain clinical  trials for  the Company's products
will be  conducted by  government-sponsored agencies  and consequently will be
dependent on government participation and funding.  The Company will have less
control over  the timing and other aspects of these clinical trials than if it
conducted the  trails entirely  by itself,  and there can be no assurance that
these trials will commence or be completed as the Company expects or that they
will be  conducted successfully.   Failure  to commence or complete any of its
planned clinical trials could have a material adverse effect on the Company.

     Risks Relating to Corporate Collaborations

     Progenics' business  strategy includes  entering into collaborations with
corporate partners,  primarily pharmaceutical  companies,  for  the  research,
development (including  clinical  development),  commercialization,  marketing
and/or distribution  of certain  of its  product candidates.  The Company  has
entered into  a significant  corporate collaboration  with  BMS  covering  the
Company's most  advanced product  candidates.  Pursuant to its agreements with
BMS,  Progenics  has  granted  to  BMS  the  exclusive  worldwide  license  to
manufacture, use  and sell  GMK and  MGV  and  any  other  products  to  which
Progenics has  rights that include the GM2 or GD2 ganglioside antigens for the
treatment or  prevention of human cancer.  The Company has also entered into a
collaboration with Roche pursuant to which the Company has granted to Roche an
exclusive worldwide  license to  certain applications of the Company's HIV co-
receptor technology.   As a result of the governing agreements, the Company is
dependent on BMS and Roche to fund testing, to make certain regulatory filings
and to  manufacture and market existing and any future products resulting from
the collaborations.  There can be no assurance that the arrangements with BMS,
Roche  or  any  other  collaborator  will  be  scientifically,  clinically  or
commercially  successful.     In  the  event  that  any  such  arrangement  is
terminated, such  action could  adversely  affect  the  Company's  ability  to
develop,  commercialize,   market  and   distribute  certain  of  its  product
candidates.   The Company's  product candidates  will only  generate milestone
payments  and   royalties  after   significant  preclinical   and/or  clinical
development,  the   procurement  of   requisite  regulatory   approvals,   the
establishment of manufacturing capabilities and/or the successful marketing of
the product.

     The amount  and timing  of resources dedicated by BMS, Roche or any other
collaborator to  their   respective collaborations  with the  Company  is  not
within the Company's control.  If any such collaborator breaches or terminates
its agreements  with the  Company,  or  fails  to  conduct  its  collaborative
activities in a timely manner, the commercialization of product candidates may
be adversely  affected.    There  can  be  no  assurance  that  the  Company's
collaborative partners  will  not  change  their  strategic  focus  or  pursue
alternative technologies  or develop  alternative products either on their own
or in  collaboration with  others, including  the Company's  competitors, as a
means  for   developing  treatments   for  the   diseases  targeted  by  these
collaborative programs.   For example, both BMS and Roche market products that
may compete  against the  products  that  may  result  from  their  respective
collaborations with the Company.  The Company's business also will be affected
by the  effectiveness of  its corporate partners in marketing any successfully
developed products.  A reduction in sales efforts or a discontinuance of sales
of any developed products by any collaborative partner could result in reduced
revenues and have a material adverse effect on the Company.

     There can be no assurance that the Company's existing strategic alliances
will continue  or be  successful or  that the Company will receive any further
research funding  or milestone  or royalty payments. If the Company's partners
do not  develop products under these collaborations, there can be no assurance
that the  Company would  be able  to do  so.   Disputes may  arise between the
Company and  its collaborators as to a variety of matters, including ownership
of intellectual  property rights.   These  disputes may  be both expensive and
time-consuming  and   may  result   in   delays   in   the   development   and
commercialization of  certain product  candidates.   There can be no assurance
that the  Company will  be able  to  negotiate  any  additional  collaborative
arrangements, that  such arrangements  will be  available to  the  Company  on
acceptable terms  or that  any such  relationships, if  established,  will  be
scientifically  or  commercially  successful.    Furthermore,  any  additional
collaborations would  likely be  subject to some or all of the risks described
above with respect to the Company's current collaborations.

     History of  Operating Losses  and Accumulated Deficit; No Product Revenue
and Uncertainty of Future Profitability

     The Company  has incurred  substantial losses since its inception.  As of
December 31,  1998, the  Company had  an accumulated  deficit of approximately
$17.2 million.   Such  losses have resulted principally from costs incurred in
the Company's research and development programs and general and administrative
costs associated  with the  Company's development.  The Company has derived no
significant revenues  from product  sales  or  royalties  and  no  significant
product sales  or royalties  are likely  for a  number of years, if ever.  The
Company may  incur additional  operating losses  in the  future,  which  could
increase significantly  as the  Company expands development and clinical trial
efforts.    The  Company's  ability  to  achieve  long-term  profitability  is
dependent in  part on obtaining regulatory approvals for products and entering
into agreements  for commercialization  of such  products.   There can  be  no
assurance that  such regulatory  approvals will be obtained or such agreements
will be  entered into.   The  failure to  obtain any such necessary regulatory
approvals or  to enter  into any  such necessary  agreements  could  delay  or
prevent the  Company from  achieving profitability  and would  have a material
adverse effect  on the  Company.   Further, there can be no assurance that the
Company's operations  will be profitable even if any product under development
by the Company or any collaborators is commercialized.

     Need for Additional Financing and Uncertain Access to Capital Funding

     Progenics' current development projects require substantial capital.  The
Company does not have committed external sources of funding for certain of its
drug discovery  and development projects.  The Company may require substantial
additional funds  to  conduct  development  activities,  preclinical  studies,
clinical  trials   and   other   activities   relating   to   the   successful
commercialization of  potential products.  There can be no assurance, however,
that the  Company will be able to obtain additional funds on acceptable terms,
if at  all.   If adequate funds are not available, the Company may be required
to delay, reduce the scope of or eliminate one or more of its programs; obtain
funds through  arrangements with  collaborative partners  or others  that  may
require the  Company to  relinquish rights  to certain  of  its  technologies,
product candidates  or products  that the  Company  would  otherwise  seek  to
develop or  commercialize itself;  or license the rights to such technologies,
product candidates or products on terms that are less favorable to the Company
than might  otherwise be available.  If the Company raises additional funds by
issuing equity securities, further dilution to stockholders may result and new
investors could have rights superior to existing stockholders.

     Limited Manufacturing Capabilities

     In order  to commercialize its product candidates successively, Progenics
and/or  its  collaborators  must  be  able  to  manufacture  its  products  in
commercial  quantities,   in  compliance   with  regulatory  requirements,  at
acceptable costs  and in  a timely  manner.   The manufacture  of the types of
biopharmaceutical products  being developed  by the Company (independently and
with  its  collaborators)  presents  several  risks  and  difficulties.    The
manufacture of some or all of the Company's product candidates can be complex,
difficult to  accomplish even  in small quantities, difficult to scale-up when
large scale  production is  required and subject to delays, inefficiencies and
poor or  low yields  of quality  products.  Although Progenics has constructed
two pilot-scale  manufacturing facilities,  one for the production of vaccines
and one  for the production of recombinant proteins, which it believes will be
sufficient to  meet the  Company's initial  needs for  clinical trials,  these
facilities may  be insufficient  for all of its late-stage clinical trials and
for its  commercial-scale manufacturing  requirements, if  any.   Furthermore,
there can  be no  assurance that  the  Company's  collaboration  with  Genzyme
Transgenics for  the transgenic  production of  PRO 542 will result in a cost-
effective means  for the  production of PRO 542.  Accordingly, the Company may
be required  to expand  its manufacturing  staff and facilities and obtain new
facilities or  contract with corporate collaborators or other third parties to
assist with  production.   For manufacture  of some of its products, Progenics
may contract  with third  party  manufacturers.    In  employing  third  party
manufacturers, Progenics  will not  control all  aspects of  the manufacturing
process.   There can  be no  assurance that the Company will be able to obtain
from third  party manufacturers  adequate supplies  in a  timely  fashion  for
commercialization, or  that commercial  quantities of  any such  products,  if
approved for  marketing, will  be available  from  contract  manufacturers  at
acceptable costs.  In the event the Company decides to establish a commercial-
scale manufacturing  facility, the Company will require substantial additional
funds and  will be required to hire and train significant numbers of employees
and comply  with the  extensive regulations  applicable to  such  a  facility.
There can  be no  assurance that  Progenics will  be able  to develop  a  cGMP
manufacturing facility  sufficient for all clinical trials or commercial-scale
manufacturing.   The cost  of manufacturing  certain products  may  make  them
prohibitively expensive.


                                     27
<PAGE>
     Availability of Materials

     There can  be no  assurance that  sufficient quantities  of raw materials
will be  available to  support continued  research, development  or commercial
manufacture of  any of  the Company's planned products.  The Company currently
obtains supplies  of critical materials used in production of GMK and MGV from
single sources.   Specifically, commercialization of the Company's GMK and MGV
cancer vaccine  candidates requires  an adjuvant,  QS-21, available  only from
Aquila.   The Company  has entered  into a  license and  supply agreement with
Aquila pursuant  to which  Aquila agreed to supply the Company with all of its
requirements for  QS-21 for  use in certain ganglioside-based cancer vaccines,
including GMK  and MGV.  In connection  with the  Company's collaboration with
BMS, Progenics  granted to  BMS a non-exclusive sublicense under the Company's
license and  supply agreement  with Aquila,  and BMS  entered  into  a  supply
agreement with  Aquila.  There can be no assurance that Aquila will be able to
supply sufficient  quantities of  QS-21 to  the Company  or BMS  or  that  the
Company or  BMS will  have the  right or  capability to manufacture sufficient
quantities of  QS-21 to  meet its needs if Aquila is unable or unwilling to do
so.   There can be no assurance that the Company will not be subject to delays
or disruption in the supply of this component.  Any delay or disruption in the
availability of  raw materials  could have  a material  adverse effect  on the
Company.

     Government Regulation; No Assurance of Regulatory Approval

     The Company  and its  products are subject to comprehensive regulation by
the FDA in the United States and by comparable authorities in other countries.
These national agencies and other federal, state, and local entities regulate,
among  other   things,  the   preclinical  and   clinical   testing,   safety,
effectiveness, approval,  manufacture, labeling,  marketing, export,  storage,
record keeping,  advertising, and  promotion of the Company's products.  Among
other requirements, FDA approval of the Company's products, including a review
of the  manufacturing processes  and facilities used to produce such products,
will be  required before  such products  may be marketed in the United States.
The process  of obtaining  FDA approvals  can be  costly, time  consuming  and
subject to  unanticipated  delays,  and  the  Company  has  had  only  limited
experience in  filing and  pursuing applications  necessary to gain regulatory
approvals.   The Company  is also  subject to  numerous  and  varying  foreign
regulatory requirements  governing the  design and  conduct of clinical trials
and the  manufacturing and  marketing of its products.  The foreign regulatory
approval process  may include  all of  the risks associated with obtaining FDA
approval set  forth above.   There can be no assurance that the Company or its
partners will  file for regulatory approvals or receive necessary approvals to
commercialize product  candidates in a timely manner in any market.  Delays in
receipt of  or failure  to  receive  regulatory  approvals,  or  the  loss  of
previously received  approvals, would  have a  material adverse  effect on the
Company.

     Both before  and after  approval is obtained, a product, its manufacturer
and the  sponsor of  the marketing  application for the product are subject to
comprehensive regulatory  oversight.  Violations of regulatory requirements at
any stage,  including  the  preclinical  and  clinical  testing  process,  the
approval process,  or post-approval marketing activities may result in various
adverse consequences.


                                     28
<PAGE>
     Dependence On Third Parties

     In addition  to its  reliance on  corporate  collaborators,  the  Company
relies in  part on  third parties to perform a variety of functions, including
research  and  development,  manufacturing,  clinical  trials  management  and
regulatory affairs.   As  of February  28,  1999,  the  Company  had  only  40
full-time employees.  The Company is party to several collaborative agreements
which  place   substantial  responsibility   on  third  parties  for  clinical
development  of   the  Company's  products.    The  Company  also  in-licenses
technology from  medical  and  academic  institutions  in  order  to  minimize
investments in  early research and enters into collaborative arrangements with
certain  of  these  entities  with  respect  to  clinical  trials  of  product
candidates.

     Except for payments made to the Company under its collaborations with BMS
and Roche,  most of  the Company's  revenues to  date have  been derived  from
federal research  grants.   The government's obligation to make payments under
these grants  is subject  to appropriation  by the  United States Congress for
funding in  each year.    Moreover,  it  is  possible  that  Congress  or  the
government agencies  that administer  these government  research programs will
determine to  scale  back  these  programs  or  terminate  them  or  that  the
government will  award future  grants to competitors of the Company instead of
the Company.  In addition, there can be no assurances that the Company will be
awarded any  such grants  in the  future or that any amounts derived therefrom
will not  be less  than those  received to  date.   Certain of  the  Company's
clinical trials  are expected  to be  partially paid  for by government funds.
Any future  reduction in  the funding the Company receives either from federal
research grants  or with  respect to  clinical trials  could have  a  material
adverse effect on the Company.

     There can  be no  assurance that  Progenics will be able to establish and
maintain any  of the  relationships described above on terms acceptable to the
Company, that  the Company  can enter  into these  arrangements without  undue
delays or  expenditures or  that these  arrangements will allow the Company to
compete successfully against other companies.

     Lack of Sales and Marketing Experience

     If FDA  and other  approvals are  obtained with  respect to  any  of  its
products, Progenics  expects to  market  and  sell  its  products  principally
through distribution,  co-marketing, co-promotion  or  licensing  arrangements
with third  parties.   The Company's agreements with BMS and Roche grant these
collaborators the  exclusive right to market any products resulting from their
respective collaborations.  Progenics has no experience in sales, marketing or
distribution.   To the  extent that  the Company enters into distribution, co-
marketing, co-promotion  or licensing  arrangements for the marketing and sale
of its products, any revenues received by the Company will be dependent on the
efforts of third parties.  The Company would not control the amount and timing
of marketing  resources such  third parties  would  devote  to  the  Company's
products. In  addition, if  the Company markets products directly, significant
additional expenditures  and management resources would be required to develop
an internal  sales force.   There can be no assurance that the Company will be
able to establish a successful sales force, should it choose to do so.

     Dependence on  and Uncertainty  of Protection  of Patents and Proprietary
Rights

     The Company's  success is dependent in part on obtaining, maintaining and
enforcing patent  and other  proprietary  rights.    The  patent  position  of
biotechnology and  pharmaceutical firms  is highly uncertain and involves many
complex legal  and technical  issues.   There is no clear policy involving the
breadth of  claims allowed in such cases, or the degree of protection afforded
under such  patents.   Accordingly, there  can be  no  assurance  that  patent
applications owned  by or licensed to the Company will result in patents being
issued or  that,  if  issued,  the  patents  will  afford  protection  against
competitors with similar technology.


                                     29
<PAGE>
     The issuance  of a  patent is  not conclusive  as to  its validity or the
enforceable scope  of its  claims.  The validity or enforceability of a patent
after its  issuance by  the patent  office can  be challenged  in  litigation.
There can  be no  assurance that  the Company's  issued patents or any patents
subsequently issued  to or  licensed by  the Company  will not be successfully
challenged.   Moreover, the  cost of  litigation to  uphold  the  validity  of
patents and to prevent infringement can be substantial.  If the outcome of the
litigation is  adverse to  the patent  owner, third parties may be able to use
the patented  invention without  payment.  Moreover, there can be no assurance
that the  Company's patents  will not  be infringed  or  successfully  avoided
through design innovation.

     There  may  be  patent  applications  and  issued  patents  belonging  to
competitors that  may require the Company to alter its products, pay licensing
fees or  cease certain  activities.   If the  Company's products conflict with
patents that  have been  or may  be granted  to competitors,  universities  or
others, such  other persons  could bring  legal actions  against  the  Company
claiming damages  and seeking  to enjoin  manufacturing and  marketing of  the
affected products.  If any  such actions  are successful,  in addition  to any
potential liability  for damages,  the Company  could be  required to obtain a
license in  order to  continue to manufacture or market the affected products.
There can be no assurance that the Company would prevail in any such action or
that any  license required  under any  such patent  would be made available on
acceptable terms or at all.

     ADARC is  a co-owner  with the  Company of one of the patent applications
relating to  the HIV  co-receptor CCR5  and upon  which the  Company's HIV co-
receptor/fusion program  is based.   Unless the Company acquires from ADARC an
exclusive license  to ADARC's  rights in this patent application, there can be
no assurance  that ADARC  will not  license such patent to a competitor of the
Company.   Additionally, Progenics  has filed  a number  of U.S.  and  foreign
patent applications (one of which is owned jointly with ADARC) relating to the
discovery of the HIV co-receptor CCR5.  The Company is aware that other groups
have claimed  discoveries similar  to those  covered by  the Company's  patent
applications.   These groups  may have  made their  discoveries prior  to  the
discoveries covered  by the  Company's patent  applications and may have filed
their applications  prior to  the Company's  patent applications.  The Company
does not  expect to know for several years the relative strength of its patent
position as compared to these other groups.

     The Company  is required  to make  substantial cash  payments and achieve
certain  milestones   and  satisfy   certain  conditions,  including,  without
limitation, filing INDs, obtaining product approvals and introducing products,
to maintain  its rights  under licenses  granted to the Company, including its
licenses from  Sloan-Kettering and  Columbia University.    There  can  be  no
assurance that  the Company  will be  able to  maintain its rights under these
licenses.   Termination of  any of  such licenses  could result in the Company
being  unable   to  develop  and/or  commercialize  any  related  product  and
consequently could have a material adverse effect on the Company.

     In  addition   to  the   patents,  patent   applications,  licenses   and
intellectual property  processes described  above, the  Company also relies on
unpatented technology,  trade secrets  and information.   No  assurance can be
given that  others will  not independently  develop  substantially  equivalent
information  and   techniques  or  otherwise  gain  access  to  the  Company's
technology or  disclose such  technology, or  that the Company can effectively
protect  its   rights  in   such  unpatented  technology,  trade  secrets  and
information. The  Company requires  each of  its  employees,  consultants  and
advisors to  execute a  confidentiality agreement  at the  commencement of  an
employment or  consulting relationship  with the  Company.   There can  be  no
assurance however, that these agreements will provide effective protection for
the Company's  information in  the event  of unauthorized use or disclosure of
such confidential information.

     Dependence Upon Key Personnel; Attraction and Retention of Personnel

     Progenics  is  dependent  upon  certain  key  management  and  scientific
personnel.   In particular,  the loss  of Dr.  Maddon could  have a materially
adverse effect  on Progenics  unless a  qualified replacement  could be found.
Progenics maintains  a key  man life  insurance policy  on Dr.  Maddon in  the
amount of  $2.5 million.   The  Company has  an employment  agreement with Dr.
Maddon that expires in December 2001.

     Competition   for    qualified   employees   among   companies   in   the
biopharmaceutical industry is intense.  Progenics' future success depends upon
its ability  to attract,  retain and  motivate highly  skilled employees.   In
order to  commercialize its products successfully, the Company may be required
to  expand   substantially  its   personnel,  particularly  in  the  areas  of
manufacturing,  clinical   trials  management,  regulatory  affairs,  business
development and marketing.  There can be no assurance that the Company will be
successful in hiring or retaining qualified personnel.

     Uncertainty Related to Health Care Reform Measures and Reimbursement

     In recent  years, there have been numerous proposals to change the health
care system  in the  United States.   Some  of these  proposals have  included
measures that would limit or eliminate payments for certain medical procedures
and treatments  or  subject  the  pricing  of  pharmaceuticals  to  government
control.  In addition, as a result of the trend towards managed health care in
the United  States, as  well as  legislative proposals  to  reduce  government
insurance programs,  third-party payors are increasingly attempting to contain
health care  costs by limiting both coverage and the level of reimbursement of
new drug  products.   Consequently, significant  uncertainty exists  as to the
reimbursement status  of newly-approved  health care products.  If the Company
or any  of its  collaborators succeeds  in bringing  one or more of Progenics'
products to  market, there  can be  no assurance  that third-party payors will
establish  and   maintain  price  levels  sufficient  for  realization  of  an
appropriate  return  on  the  Company's  investment  in  product  development.
Significant changes  in the  health  care  system  in  the  United  States  or
elsewhere, including  changes resulting  from adverse  trends  in  third-party
reimbursement programs,  could have  a material adverse effect on the Company.
Such changes  also could  have a  material adverse  effect  on  the  Company's
ability to raise capital.  Furthermore, the Company's ability to commercialize
products may  be adversely  affected to  the extent that such proposals affect
the Company's collaborators.

     Risk of Product Liability; Limited Availability of Insurance

     The Company's  business exposes  it to  potential product liability risks
which are  inherent in  the testing,  manufacturing,  marketing  and  sale  of
pharmaceutical products,  and there  can be no assurance that the Company will
be able  to avoid product liability exposure.  Product liability insurance for
the biopharmaceutical  industry is generally expensive, when available at all.
The Company has obtained product liability insurance coverage in the amount of
$5 million  per occurrence,  subject to  a $5  million  aggregate  limitation.
However, there  can be  no assurance  that  the  Company's  present  insurance
coverage is  now or will continue to be adequate.  In addition, certain of the
Company's license  and collaborative  agreements require the Company to obtain
product liability  insurance, and  it is  possible  that  future  license  and
collaborative agreements may also include such a requirement.  There can be no
assurance that  in the future adequate insurance coverage will be available at
a reasonable cost or that a product liability claim or recall would not have a
material adverse effect on the Company.

     Hazardous Materials; Environmental Matters

     The Company's  research and  development work and manufacturing processes
involve the  use of  hazardous, controlled  and radioactive  materials.    The
Company is  subject to federal, state and local laws and regulations governing
the use,  manufacture, storage,  handling and  disposal of  such materials and
certain waste  products.   Despite precautionary procedures implemented by the
Company for  handling and  disposing of such materials, the risk of accidental
contamination or  injury cannot  be eliminated.   In  the  event  of  such  an
accident, the  Company could  be held  liable for  any  damages  that  result.
Although the  Company believes  that it  is  in  compliance  in  all  material
respects with  applicable environmental  laws and regulations, there can be no
assurance that  the Company will not be required to incur significant costs to
comply with  environmental laws  and regulations  in the  future, or  that the
Company will  not be  materially and  adversely affected  by current or future
environmental laws or regulations.

     Control by Existing Stockholders; Anti-Takeover Provisions

     Certain  stockholders   of  the   Company,  including   Dr.  Maddon   and
stockholders affiliated with Tudor Investment Corporation, beneficially own or
control a  substantial portion  of the  outstanding shares  of  the  Company's
Common Stock  (the "Common  Stock") and therefore may have the ability, acting
together, to elect all of the Company's directors, to determine the outcome of
corporate actions  requiring stockholder  approval and  otherwise control  the
business of  the Company.   Such  control could have the effect of delaying or
preventing a  change in  control of  the Company  and  consequently  adversely
affect the market price of the Common Stock.  In addition, the Company's Board
of Directors  is authorized  to issue  from time  to time  shares of Preferred
Stock, without  further stockholder  authorization, in  one or more designated
series or  classes.   The issuance  of Preferred  Stock, as  well  as  certain
provisions in  certain of  the  Company's  stock  options  which  provide  for
acceleration of  exercisability upon  a change  of control  of the Company and
certain provisions  of the  Delaware General  Corporation Law (Section 203, in
particular), could  make the  takeover of  the Company  or the  removal of the
Company's management  more difficult,  discourage hostile  bids for control of
the Company  in which  stockholders may  receive a premium for their shares of
Common Stock  or otherwise  dilute the  rights of  holders of Common Stock and
depress the market price of the Common Stock.

     Future Sales  of Common  Stock;  Registration  Rights;  Possible  Adverse
Effect on Future Market Price

     A substantial  number of outstanding shares of Common Stock and shares of
Common Stock  issuable upon  exercise of  outstanding options and warrants are
eligible for  sale in  the public  market.   Sales of  substantial numbers  of
shares of  Common Stock  could  adversely  affect  prevailing  market  prices.
Certain stockholders  of the  Company are  entitled  to  certain  rights  with
respect to the registration of shares of Common Stock for offer or sale to the
public.   The Company  has filed a Form S-8 registration statement registering
shares issuable  pursuant to  the Company's  stock option plans.  Any sales by
existing stockholders  or holders  of options  or warrants may have an adverse
effect on  the Company's ability to raise capital and may adversely affect the
market price of the Common Stock.

Item 2.   Properties

     Progenics  leases   approximately  24,000   square  feet  of  laboratory,
manufacturing and  office space  in Tarrytown,  New York.   The Company leases
this space under an operating lease which terminates in December 1999, with an
option on  the part  of Progenics to extend the lease for one additional year.
Progenics has two pilot production facilities within its leased facilities for
the manufacture  of products  for clinical  trials.  The Company believes that
its current facilities are adequate for its current needs.

Item 3.   Legal Proceedings

     The Company is not a party to any material legal proceedings.

Item 4.   Submission of Matters to a Vote of Security Holders

     Not applicable.

Stock.   As of  December 31, 1998,  of the  $17,112,000 in  proceeds  (net  of
underwriting discounts  and commissions  but not  of associated expenses) from
the Company's  initial public  offering, approximately  $14,284,000  had  been
applied to  research and  development and  general operating  expenses and the
remainder  had  been  applied  to  temporary  investments  in  corporate  debt
securities and money market funds.  With the exception of compensation paid to
the officers  and certain  of the  directors of  the Company  as employees  or
consultants, no  amounts paid  in respect  of operating  expenses were paid to

owning 10% or  more of any class of equity securities of the Company or to any
affiliates of the Company.

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

     Overview

     Progenics is  a biopharmaceutical company focusing on the development and
commercialization of  innovative products  for the treatment and prevention of
cancer and viral diseases.  The Company commenced principal operations in late
1988 and since that time has been engaged primarily in organizational efforts,
including recruitment  of scientific  and management  personnel, research  and
development  efforts,   development   of   its   manufacturing   capabilities,
establishment of  corporate collaborations  and raising  capital.  In order to
commercialize the  principal products  that the Company has under development,
the Company  will need  to address  a number  of technological  challenges and
comply with  comprehensive regulatory  requirements.   Accordingly, it  is not
possible to predict the amount of funds that will be required or the length of
time that  will pass before the Company receives revenues from sales of any of
its products.   To  date, product  sales  have  consisted  solely  of  limited
revenues from  the sale  of research reagents.  The Company expects that sales
of research  reagents in  the future  will  not  significantly  increase  over
current levels.   The Company's other sources of revenues through December 31,
1998 have  been payments received under its collaboration agreements, research
grants and  contracts related  to the  Company's cancer  and HIV  programs and
interest income.

     To date,  a majority of the Company's expenditures have been for research
and development  activities.   The  Company  expects  that  its  research  and
development expenses  will increase significantly as its programs progress and
the Company makes  filings  for related regulatory approvals.  The Company had
recurring losses  prior to 1997 and  had at  December 31, 1998  an accumulated
deficit of $17,208,000.   The Company  has financed  its  operations primarily
through the  private  sale and issuance of equity securities, a line of credit
that has since  been  repaid  and  terminated,  payments  received  under  its
collaboration  with  BMS  beginning  in July 1997, payments received under its
collaboration  with  Roche  beginning in January 1998  and the proceeds of the
Company's initial  public offering in November 1997.  The Company will require
additional funds to complete the development of its products, to fund the cost
of clinical  trials,  and  to  fund  operating  losses which  are  expected to
continue for the foreseeable future.  The Company does not expect its products
under development to be commercialized in the near future.

     In July  1997, Progenics  entered into  a Joint  Development  and  Master
License Agreement  (the BMS  Agreements).  These agreements provide for BMS to
fund further  development, clinical  trials and  regulatory filings related to
GMK and  MGV.   Consequently, Progenics  does not  expect to  make significant
additional expenditures  relating to  these product  candidates for so long as
these agreements  remain in  force.   In connection  with the establishment of
this collaboration,  BMS paid  to the  Company in  July 1997  an aggregate  of
approximately  $13.3   million,  representing   reimbursement   for   expenses
previously incurred  by Progenics in the development of GMK and MGV, licensing
fees and  reimbursement of clinical development costs for the period April 15,
1997 to  September 30,  1997.   In connection with payments made by BMS to the
Company under  the BMS License Agreement, the Company made certain payments to
licensors and  incurred other  related  expenses.    See  "Business--  General
Overview-- BMS Collaboration."

Results of Operations

Years Ended December 31, 1997 and 1998

     Contract research  and development  revenue decreased from $14,591,000 in
1997 to  $11,135,000 in  1998.   In connection with the BMS License Agreement,
the Company  received a  licensing fee in 1997 and a milestone payment in 1998
and reimbursement  of clinical  development during  both years.  Revenues from
research grants  increased from  $665,000 in  1997 to $1,251,000 in 1998.  The
increase resulted  from the  funding of  a greater  number of  grants in 1998.
Sales of  research reagents increased from $57,000 in 1997 to $180,000 in 1998
resulting from  increased orders  for such  reagents during  1998.    Interest
income increased  from $301,000  in 1997  to $1,455,000  in 1998  due  to  the
increase in  cash available  for investing  as the  Company received continued
funding under  the BMS  License Agreement  and invested  the proceeds  of  its
initial public offering completed in November 1997.

     Research and  development expenses  increased from  $7,364,000 in 1997 to
$8,296,000 in  1998.   The increase was principally due to additional costs of
manufacturing GMK  and monitoring  the Company's  Phase  III  clinical  trials
during 1998, and additional costs of manufacturing PRO 542.


                                     35
<PAGE>
     General and  administrative expenses increased from $2,222,000 in 1997 to
$3,841,000 in  1998.   The increase  was principally  due to  the increase  of
professional  fees  associated  with  the  negotiation  of  potential  license
agreements and increased costs of investor relations associated with operating
as a public entity for the full year of 1998.  Interest expense decreased from
$312,000 in 1997 to $43,000 in 1998 as a result of the borrowings under a line
of credit  that commenced in March 1997 were repaid in July 1997.  The Company
also  had   more  interest   expense  on   capitalized  leases   during  1997.
Depreciation and  amortization increased  from $319,000 in 1997 to $388,000 in
1998.   The Company  purchased additional  laboratory and  office equipment in
1998.

     In 1998, the Company was able to utilize net operating loss carryforwards
to offset its income and, therefore, had no provision for income taxes.    
In 1997, the Company recognized a provision for income taxes of $258,000 which
was based  upon  prevailing  federal  and  state  tax  rates  reduced  by  the
utilization of net operating loss carryforwards to the extent permitted by the
alternative minimum tax rules.

     The Company's net income in 1997 was $5,139,000 compared to net income of
$1,453,000 in 1998.

Years Ended December 31, 1996 and 1997

     Contract research and development revenue increased from $318,000 in 1996
to  $14,591,000   in  1997  as  the  Company  received  a  licensing  fee  and
reimbursement of clinical development costs in connection with the BMS License
Agreement.   Revenues from  research grants increased from $203,000 in 1996 to
$665,000 in  1997.  The increase resulted from the funding of a greater number
of grants  in 1997.  Sales of research reagents decreased from $98,000 in 1996
to $57,000  in 1997  resulting from  decreased orders for such reagents during
1997.  Interest income increased from $106,000 in 1996 to $301,000 in 1997 due
to the  increase in  cash available  for investing  as  the  Company  received
funding from  the BMS  License Agreement  in July  1997 and its initial public
offering in November 1997.

     Research and  development expenses  increased from  $3,700,000 in 1996 to
$7,364,000 in 1997.  The increase was principally due to payments to licensors
in  connection   with  the   BMS  License   Agreement,  additional   costs  of
manufacturing GMK  in 1997  for the  Company's Phase  III clinical  trials and
compensation expense related to the issuance of stock options to employees and
consultants.

     General and  administrative expenses decreased from $2,808,000 in 1996 to
$2,222,000 in  1997.   The decrease  was  principally  due  the  reduction  of
professional fees  and printing  costs that were associated with the Company's
unsuccessful efforts  to sell  Common Stock in a registered public offering in
1996.   Interest expense increased from $51,000 in 1996 to $312,000 in 1997 as
a result  of borrowings  commencing in  March 1997  under a  line  of  credit.
Depreciation and  amortization remained  relatively unchanged from $309,000 in
1996 to $319,000 in 1997.

     In 1997,  the Company recognized a provision for income taxes of $258,000
which was  based upon  prevailing federal  and state  tax rates reduced by the
utilization of net operating loss carryforwards to the extent permitted by the
alternative minimum tax rules.

     The Company's  net loss  in 1996 was $6,143,000 compared to net income of
$5,139,000 in 1997.

     Liquidity and Capital Resources

     The Company  has funded  its operations since inception primarily through
private  placements   of  equity  securities,  loans  that  were  subsequently
converted into  equity securities,  a line  of  credit  that  was  repaid  and
terminated, payments  received under  collaboration agreements including those
with BMS and Roche, an initial public offering, funding under  research grants
and contracts, interest on investments and the sale of research reagents.


                                     36
<PAGE>
     During the  fourth quarter  of 1995  and the  first quarter  of 1996, the
Company raised  $897,000 and  $4,777,000 in  net proceeds  from  the  sale  of
approximately 44,900  units and  241,203 units,  respectively,  in  a  private
placement of  shares of  the Company's  Series C  Preferred Stock  in  a  unit
offering.   Each $20.00  unit ("Series  C Unit")  consisted of  four shares of
Series C  Preferred Stock and one warrant entitling the holder to purchase one
share of  Series C Preferred Stock for $5.00 any time within five years of the
date of  issuance ("Series  C Warrant").   In  November 1997,  all outstanding
shares of  preferred stock of the Company were converted into shares of Common
Stock in  connection with the Company's initial public offering.  In addition,
during December  1995, a  note payable  in the  aggregate principal  amount of
$1,200,000, plus  accrued and  unpaid interest  of $24,000, was converted into
approximately 61,200 Series C Units.  At December 31, 1998, there were 347,249
Series C  Warrants outstanding  which if  exercised in  full would  result  in
$1,736,000 of  net proceeds  to the Company and the issuance of 260,455 shares
of Common Stock.

     In March  1997, the  Company entered  into a  credit agreement with Chase
Capital Bank (the "Chase Loan Agreement"), which provided for borrowings of up
to $2,000,000.  The Company  borrowed the  full amount  available  under  this
facility in drawings made between March and June 1997.  Borrowings made by the
Company had  a stated  interest rate  of prime  and were  used to fund working
capital.   The Company  repaid all  outstanding borrowings  in July  1997 from
proceeds of  payments received by the Company under the BMS License Agreement.
Upon such repayment, the line of credit terminated.  The Company's obligations
under the  Chase Loan  Agreement were  guaranteed by  two  affiliates  of  the
Company, and  in consideration  of such guarantee these affiliates were issued
between March and July 1997 warrants to purchase an aggregate of 70,000 shares
of Common  Stock at  an exercise  price of  $4.00 per share as a result of the
completion of the Company's  initial  public offering.   At December 31, 1998,
all 70,000 warrants were outstanding and fully exercisable.

     In November  1997, the  Company sold  2,300,000 shares of Common Stock in
its initial  public offering.   After  deducting  underwriting  discounts  and
commissions  and   other  expenses,  the  Company  received  net  proceeds  of
$16,015,000.   The net  proceeds were invested in short-term, interest bearing
investment grade securities pending further application by the Company.

     At December  31,  1998,  the  Company  had  cash,  cash  equivalents  and
marketable  securities  totaling  $24,650,000  compared  with  $23,624,000  at
December 31, 1997.  The Company's facility lease was extended from May 1998 to
December 2000  at a  monthly rental  of $54,000.  The Company expects to incur
during 1999  costs of  approximately $500,000  for leasehold  improvements and
equipment to enhance its manufacturing capabilities.

     The Company  believes  that  its  present  capital  resources  should  be
sufficient to  fund operations  at least through the end of 2000, based on the
Company's current  operating plan.   No assurance can be given that there will
be no  change that would consume the Company's liquid assets before such time.
The Company  will require substantial funds to conduct development activities,
preclinical studies,  clinical trials  and other  activities relating  to  the
commercialization of  any potential products.  In addition, the Company's cash
requirements may  vary materially from those now planned because of results of
research and development and product testing, potential relationships with in-
licensors and  collaborators, changes  in  the  focus  and  direction  of  the
Company's research  and development  programs, competitive  and  technological
advances, the  cost of  filing, prosecuting,  defending and  enforcing  patent
claims, the regulatory approval process, manufacturing and marketing and other
costs associated  with the  commercialization of products following receipt of
regulatory approvals and other factors.  The Company has no committed external
sources of  capital and,  as discussed  above, expects  no significant product
revenues for  a number  of years  as it  will take  at least that much time to
bring the  Company's products  to the commercial marketing stage.  The Company
may seek  additional financing,  such as through future offerings of equity or
debt securities  or agreements  with corporate partners and collaborators with
respect to  the development  of  the  Company's  technology,  to  fund  future
operations.  There can be no assurance, however, that the Company will be able
to obtain additional funds on acceptable terms, if at all.

     Year 2000 Compliance

     The "Year  2000" problem  relates to  many currently installed computers,
software,  and   other  equipment   that   relies   on   embedded   technology
(collectively, "Business Systems").  These Business Systems are not capable of
distinguishing 21st  century dates  from 20th  century dates.  As a result, in
less than  one year,  Business Systems  used by many companies, in a very wide
variety of  applications, will  experience operating  difficulties unless they
are  modified,   upgraded,  or  replaced  to  adequately  process  information
involving, related  to or  dependent upon  the century  change.  If a Business
System used  by the  Company or  a third  party dealing with the Company fails
because of  the inability  of the  Business System  to properly  read  a  21st
century date, the results could have a material adverse effect on the Company.
The Company recognizes the need to ensure its operations will not be adversely
impacted by  Year 2000 Business systems failures and has established a team to
address Year  2000 risk.    The  team  is  reviewing  the  Company's  internal
infrastructure and  believes that  it has  identified substantially all of the
major Business  Systems used  in connection with its internal operations.  The
Company has  commenced the  process of  identifying and  correcting the  major
Business Systems  that may  need to  be modified,  upgraded, or  replaced, and
expects to  complete this  process, along with remedial actions before the end
of 1999.   Costs  incurred to  date to  correct Year  2000 problems  have been
immaterial.   The Company  estimates the  total cost  to complete any required
modifications, upgrades, or replacements of affected Business Systems will not
have a  material impact  on the  Company's business  or results of operations.
This estimate  is being  monitored and  will  be  revised,  if  necessary,  as
additional information  becomes available.   The  Company also  recognizes the
risk that  suppliers of  products, services,  and collaborators  with whom the
Company transacts  business on a worldwide basis may not comply with Year 2000
requirements.     The  Company   has  initiated   formal  communications  with
significant suppliers  and collaborators  to determine the extent to which the
Company is  vulnerable if these third parties fail to remediate their own Year
2000 issues.  The review is ongoing and the Company is unable to determine, at
this time, the probability that any material supplier or collaborator will not
be able to correct any Year 2000 problem in a timely manner.  In the event any
such third  parties cannot  provide the  Company with  products, services,  or
continue the  collaborations  with  the  Company,  the  Company's  results  of
operations could  be materially  adversely affected.   Based on the above, the
Company has  yet to  develop a  comprehensive contingency plan with respect to
the Year  2000 problem.  The Company will continue to monitor its own Business
Systems and,  to the  extent possible,  evaluate the  Business Systems  of its
third party  suppliers and  collaborators to  ensure progress on this critical
matter.   However, if  the Company  identifies significant risk related to the
Year 2000  compliance or  progress deviates  from anticipated  timelines,  the
Company will develop contingency plans as deemed necessary at that time.
     
     Impact of the Adoption of Recently Issued Accounting Standard

In September  1998, the  Financial Accounting Standards Board issued Statement
of Financial  Accounting Standards  No. 133,  "Accounting for  Derivatives and
Hedging Activities" ("SFAS No.133").  SFAS No. 133 establishes a comprehensive
standard on accounting for derivatives and hedging activities and is effective
for periods  beginning after  September 15, 1999.  Management does not believe
that the  future adoption  of SFAS  No. 133 will have a material effect on the
Company's financial position and results of operations.

     Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

     At December  31, 1998, the Company did not hold any market risk sensitive
instruments.

To the Board of Directors and Stockholders of
Progenics Pharmaceuticals, Inc.:

In our  opinion, the  accompanying balance sheets and the related statements of
operations, stockholders' (deficit) equity and of cash flows present fairly, in
all material  respects, the  financial position  of Progenics  Pharmaceuticals,
Inc. (the  "Company") at  December 31,  1998 and  1997, and  the results of its
operations and  its cash  flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.
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 of these statements in accordance with
generally accepted  auditing standards  which 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, assessing  the accounting principles used and significant estimates
made  by   management,  and   evaluating  the   overall   financial   statement
presentation.   We believe  that our  audits provide a reasonable basis for the
opinion expressed above.

Notes to Financial Statements


1.   Organization and Business:

     Progenics Pharmaceuticals,  Inc. (the  "Company") is  a biopharmaceutical
     company focusing  on the  development and commercialization of innovative
     products for  the treatment  and prevention  of cancer,  viral  diseases,
     including human  immunodeficiency  virus  ("HIV")  infection,  and  other
     diseases.   Prior to July 1997, the Company was in the development stage.
     The Company  was incorporated  in Delaware  on  December 1,  1986.    The
     Company has  no products  approved for  sale by  the U.S.  Food and  Drug
     Administration.   In addition  to the  normal risks associated with a new
     business venture,  there can  be no assurance that the Company's research
     and  development  will  be  successfully  completed,  that  any  products
     developed will  obtain necessary  government regulatory  approval or that
     any approved  products will  be commercially  viable.   In addition,  the
     Company operates  in an  environment of rapid change in technology and is
     dependent  upon   the  continued   services  of  its  current  employees,
     consultants and subcontractors.

     As of  December 31,  1998, the  Company had  cash, cash  equivalents  and
     marketable securities  of $24.6 million.  The Company estimates that this
     amount will  enable it  to continue  to operate  beyond one year.  In the
     future, the  Company will  need to  raise  additional  financing  through
     public or  private equity financings, collaborative or other arrangements
     with corporate sources, or other sources of financing to fund operations.
     There can  be no  assurance that  such additional  financing, if  at  all
     available, can  be obtained  on terms  reasonable to the Company.  In the
     event the  Company is unable to raise additional capital, operations will
     need to be scaled back or discontinued.


2.   Summary of Significant Accounting Policies:

     Revenue Recognition
     The Company  has derived  all of  its product  revenue from  the sale  of
     research reagents to four customers.  Product sales revenue is recognized
     at the  time reagents  are shipped.   The  reagents are  products of  the
     Company's research  and development  efforts.   The Company  maintains no
     inventory of reagent and cost of product sales is not material.

     The Company has been awarded government research grants from the National
     Institutes of  Health (the  "NIH").  The NIH grants are used to subsidize
     the Company's  research projects ("Projects") regarding HIV.  NIH revenue
     is recognized  on a  pro rata  basis  as  subsidized  Project  costs  are
     incurred.   Such method  approximates the  straight-line basis  over  the
     lives of the Projects.

     Payments  from   Bristol-Myers  Squibb   Company,  Hoffmann-LaRoche,  the
     Department of  Defense,  Aaron  Diamond  AIDS  Research  Center  and  the
     National Institutes  of Health  (collectively the  "Collaborators")  (See
     Note 7)  for contract  research and development are used to subsidize the
     Company's research  and development efforts.  Such amounts are recognized
     as revenue as the related services are performed by the Company, provided
     the collection  of the  resulting receivable  is probable.  In situations
     where  the  Company  receives  payments  in  advance  of  performance  of
     services, such  amounts are  deferred and  recognized as  revenue as  the
     related services are performed.

     Upon the achievement of defined events certain Collaborators are required
     to make  milestone payments to the Company.  Such amounts are included in
     contract research  and development  revenue and are recognized as revenue
     upon the  achievement of  the event  and when collection of the resulting
     receivable is probable.

     Interest income is recognized as earned.

     For each of the three years in the period ended December 31, 1998, all of
     the  Company's   research  grant   revenue  and   contract  research  and
     development  revenue   came  from   the  NIH   and   the   Collaborators,
     respectively.

     Concentrations of Credit Risk
     Financial  instruments   which  potentially   subject  the   Company   to
     concentrations of  credit  risk  consist    of  cash,  cash  equivalents,
     marketable securities and receivables from the NIH and the Collaborators.
     The Company invests its excess cash in investment grade securities issued
     by corporations  and governments.  The Company has established guidelines
     that relate  to credit  quality, diversification  and maturity  and  that
     limit exposure to any one issue of securities.

     Fixed Assets
     Leasehold improvements,  furniture and fixtures, and equipment are stated
     at cost.   Furniture,  fixtures,  and  equipment  are  depreciated  on  a
     straight-line  basis  over  their  estimated  useful  lives.    Leasehold
     improvements are  amortized on a straight-line basis over the life of the
     lease or  of the  improvement, whichever  is shorter.   Expenditures  for
     maintenance and  repairs which  do not materially extend the useful lives
     of the  assets are  charged  to  expense  as  incurred.    The  cost  and
     accumulated depreciation  of assets  retired or sold are removed from the
     respective accounts  and any  gain or  loss is  recognized in operations.
     The estimated useful lives of fixed assets are as follows:

              Machinery and equipment                  5-7 years
              Furniture and fixtures                   5 years
              Leasehold improvements                   Life of lease

     Patents
     As a result of research and development efforts conducted by the Company,
     it has  applied, or  is applying,  for a  number of  patents  to  protect
     proprietary inventions.   All  costs associated with patents are expensed
     as incurred.

     Cash and Cash Equivalents
     The Company considers all highly liquid investments which have maturities
     of three  months or  less, when  acquired, to  be cash  equivalents.  The
     carrying  amount  reported  in  the  balance  sheet  for  cash  and  cash
     equivalents approximates  its fair  value.   Cash  and  cash  equivalents
     subject the  Company to  concentrations of  credit risk.  At December 31,
     1998 and  1997, the  Company had  invested approximately  $14,208,000 and
     $20,787,000 in  funds  with  two  major  investment  companies  and  held
     approximately  $229,000   and  $951,000  in  a  single  commercial  bank,
     respectively.

     Net (Loss) Income Per Share
     The Company  prepares its  per share data in accordance with Statement of
     Financial Accounting  Standards No.  128, "Earnings Per Share" ("SFAS No.
     128").

     Basic net  (loss) income per share is computed on the basis of net (loss)
     income for the period divided by the weighted average number of shares of
     common stock  outstanding during  the period.   Diluted net (loss) income
     per share  includes, where  dilutive, the  number of shares issuable upon
     exercise of  outstanding options  and  warrants  and  the  conversion  of
     preferred stock.  Disclosures required by SFAS No. 128 have been included
     in Note 12.

     Income Taxes
     The Company  accounts for  income taxes in accordance with the provisions
     of Statement  of Financial  Accounting Standards No. 109, "Accounting for
     Income Taxes"  ("SFAS No.  109").  SFAS No. 109 requires that the Company
     recognize deferred tax liabilities and assets for the expected future tax
     consequences  of   events  that  have  been  included  in  the  financial
     statements or  tax returns.   Under this method, deferred tax liabilities
     and assets  are determined on the basis of the difference between the tax
     basis of  assets and liabilities and their respective financial reporting
     amounts ("temporary  differences") at enacted tax rates in effect for the
     years in which the temporary differences are expected to reverse.

     Risks and Uncertainties
     The preparation  of financial  statements in  conformity  with  generally
     accepted accounting  principles requires management to make estimates and
     assumptions that  affect the amounts reported in the financial statements
     and  accompanying   notes.     Significant  estimates   relate   to   the
     recoverability of  fixed assets and deferred taxes.  Actual results could
     differ from those estimates.  See also Notes 1 and 7(c).

     Stock-Based Compensation
     The accompanying  financial position  and results  of operations  of  the
     Company have  been prepared  in  accordance  with  APB  Opinion  No.  25,
     "Accounting for Stock Issued to Employees" ("APB No. 25").  Under APB No.
     25, generally,  no compensation  expense is  recognized in  the financial
     statements in  connection with  the awarding  of stock  option grants  to
     employees provided  that, as of the grant date, all terms associated with
     the award  are fixed and the fair value of the Company's stock, as of the
     grant date,  is equal  to or less than the amount an employee must pay to
     acquire the  stock.   The Company  will recognize compensation expense in
     situations where  the terms of an option grant are not fixed or where the
     fair value  of the  Company's common  stock on  the grant date is greater
     than the amount an employee must pay to acquire the stock.

     Disclosures required  by Statement  of Financial Accounting Standards No.
     123,  "Accounting   for  Stock-Based   Compensation"  ("SFAS  No.  123"),
     including pro  forma operating  results  had  the  Company  prepared  its
     financial statements  in accordance  with the  fair-value-based method of
     accounting for stock-based compensation, have been included in Note 8.

     The fair  value of  options and  warrants granted  to  non-employees  for
     financing, goods or services are included in the financial statements and
     expensed over  the life  of the  debt, as  the goods  are utilized or the
     services performed, respectively.

     Comprehensive (Loss) Income
     For the  year ended  December 31,  1998, the Company adopted statement of
     Financial Accounting  Standards No. 130, "Reporting Comprehensive Income"
     ("SFAS No.  130").   Comprehensive (loss) income represents the change in
     net assets of a business enterprise during a period from transactions and
     other events  and circumstances  from non-owner  sources.   Comprehensive
     (loss) income  of the Company includes net (loss) income adjusted for the
     change in  net unrealized gain or loss on marketable securities.  The net
     effect of income taxes on comprehensive (loss) income is immaterial.  The
     disclosures required  by SFAS  No. 130  for the  years ended December 31,
     1996, 1997 and 1998 have been included in the Statements of Stockholders'
     (Deficit) Equity.

     Reclassifications
     Certain reclassifications  have been  made to the 1996 and 1997 financial
     statements to conform with the 1998 presentation.

3.   Marketable Securities

     The Company  considers its  marketable securities  to be  "available-for-
     sale," as defined by Statement of Financial Accounting Standards No. 115,
     "Accounting for  Certain Investments in Debt and Equity Securities", and,
     accordingly, unrealized  holding  gains  and  losses  are  excluded  from
     operations and  reported as  a net  amount in  a  separate  component  of
     stockholders' equity.

     As of December 31, 1997 and 1998, marketable securities had maturities of
     less than three years.  The following table summarizes the amortized cost
     basis, the  aggregate fair  value, and gross unrealized holding gains and
     losses at December 31, 1997 and 1998:

                                                         Unrealized Holding
                            Amortized      Fair      -------------------------

                           ===========  ===========  =======  ========  ======

     For the  years ended  December 31,  1997 and 1998, there were no realized
     gains and  losses from  the sale  of marketable  securities.  The Company
     computes the  cost of its investments on a specific identification basis.
     Such cost  includes the  direct costs to acquire the securities, adjusted
     for the  amortization of  any discount  or premium.   The  fair value  of
     marketable securities has been estimated based on quoted market prices.


4.   Fixed Assets:

     Fixed assets,  including amounts  under  capitalized  lease  obligations,
     consist of the following:

6.   Stockholders' Equity:

     Subsequent to  the Company's  initial public offering of its common stock
     as discussed  below, the Company is authorized to issue 40,000,000 shares
     of common stock, par value $.0013 ("Common Stock"), and 14,320,174 shares
     of preferred  stock, par  value $.001.   The  Board has  the authority to
     issue common  and preferred shares, in series, with rights and privileges
     determined by the Board.

     Prior  to  the  Company's  initial  public  offering  ("IPO"),  4,000,000
     preferred shares  were designated  as Series  A Preferred  Stock ("Series
     A"), 2,500,000  shares  were  designated  as  Series  B  Preferred  Stock
     ("Series B")  and 3,750,000  shares were designated as Series C Preferred
     Stock ("Series C") (collectively the "Preferred Stock").

     In connection  with the  issuance of Series C stock in 1995 and 1996, the
     Company issued  347,249 five-year  warrants (the  "C Warrants").   Each C
     Warrant, subsequent to the IPO, entitles the holder to purchase .75 share
     of Common  Stock at  $6.67.   The number of C Warrants and their exercise
     price  are  subject  to  adjustment  in  the  event  the  Company  issues
     additional shares  of Common Stock at below defined per share prices.  As
     of December  31, 1998, 347,249 C Warrants were issued and outstanding and
     fully exercisable into 260,455 shares of Common Stock.

     During November 1997, the Company completed an IPO of 2,300,000 shares of
     its Common  Stock, in which the Company raised approximately $16 million,
     net of  expenses and underwriting discount.  Concurrent with the IPO, all
     outstanding shares  of Preferred  Stock, were  converted  into  4,259,878
     shares of Common Stock and thereafter retired.

7.   Commitments and Contingencies:

     a. Operating Leases

        The Company  leased office  and laboratory  space under  noncancelable
        lease agreements  (the "Leases").  The Leases provided for escalations
        of the  minimum rent  during the  lease term  as  well  as  additional
        charges based  upon usage  of certain  utilities in  excess of defined
        amounts ("Additional Utility Charges").  The Company recognized rental
        expense from  the Leases on the straight-line basis.  During the years
        ended December 31,  1996, 1997 and 1998, approximately $4,000, $33,000
        and $17,000,  respectively, of  previously  recognized  rent  expense,
        which had been included as a deferred lease liability, was paid.

        On January  27, 1998,  the Company  entered into  a sublease agreement
        ("Sublease") consolidating  and extending  the Leases  for office  and
        laboratory space  from May  1, 1998  through December 31, 1999.  Fixed
        monthly rental expense totals approximately $54,000.  The Sublease can
        be extended at the option of the Company for three additional one-year
        terms; however,  the second  and third options are subject to approval
        by the landlord.

        The Company  also leases  office equipment  and  an  automobile  under
        noncancelable operating  leases.   The leases  expire at various times
        through March 2002.

        As of  December 31,  1998, future  minimum annual  payments under  all
        operating lease agreements, including the Sublease, are as follows:

                                                          Minimum

        Rental expense  totaled approximately  $645,000, $628,000 and $672,000
        for the  years ended  December 31,  1996, 1997 and 1998, respectively.
        Additional Utility Charges, were not material for these periods.

     b. Capital Leases

        The Company  leases  certain  equipment  under  various  noncancelable
        capital lease  agreements.   The leases  are for  periods ranging from
        three to  five years,  after which  the Company:  (i) either  has  the
        option or  is required to purchase the equipment at defined amounts or
        (ii) may  extend the  lease for  up to  one additional year at defined
        monthly payments  or (iii) is required to return the equipment, as per
        the respective lease agreements.

        As of  December 31,  1998, minimum  annual payments  under all capital
        leases, including  required payments  to acquire leased equipment, are

     c. Licensing and Corporate Collaboration Agreements:

       i. Universities
          The Company  (as licensee)  has a worldwide licensing agreement with
          Columbia University  ("Columbia").   The license,  as amended during
          October 1996,  provides the  Company with the exclusive right to use
          certain technology  developed on  behalf of  Columbia.  According to
          the  terms  of  the  agreement,  the  Company  is  required  to  pay
          nonrefundable  licensing   fees  ("Licensing   Fees"),  payable   in
          installments by  defined dates or, if earlier, as certain milestones
          associated  with   product  development   ("Milestones")  occur,  as
          defined, which include the manufacture and distribution of a product
          which uses  the licensed  technology by  2004.  The Company expenses
          Licensing Fees  when they become payable by the Company to Columbia.
          In addition,  the Company  is required to remit royalties based upon
          the greater of minimum royalties, as defined, or a percentage of net
          sales of  products which  utilize  the  licensed  technology  and  a
          portion of sublicensing income, as defined.  The licensing agreement
          may be  terminated by  Columbia under  certain  circumstances  which
          includes the  Company's failure  to achieve the Milestones; however,
          Columbia shall not unreasonably withhold its consent to revisions to
          the  due   dates  for   achieving  the   Milestones  under   certain
          circumstances.    If  not  terminated  early,  the  agreement  shall
          continue until  expiration,  lapse  or  invalidation  of  Columbia's
          patents on  the licensed  technology.   The Company has the right to
          terminate the  agreement at  any time  upon 90  days  prior  written
          notice.   The termination  of the  license  could  have  a  material
          adverse effect on the business of the Company.  Although the Company
          intends to  use its  best efforts  to comply  with the  terms of the
          agreement, there can be no assurances that the agreement will not be
          terminated.

          The  Company  (as  licensee)  also  has  a  non-exclusive  licensing
          agreement with  Stanford University whereby the Company has the non-
          exclusive, non-transferable right to use certain technology owned by
          the university.   According  to the  terms  of  the  agreement,  the
          Company will  be required  to remit royalties based upon the greater
          of minimum  royalties, as defined or various percentages of sales of
          products resulting  from the  use  of  licensed  patent  rights,  as
          defined.   Royalties shall  continue to  be payable, irrespective of
          termination of  this license agreement, until such time as all sales
          of products which utilize the licensed technology shall have ceased.

          In  September  1996,  the  Company  (as  licensee)  entered  into  a
          licensing agreement with The Regents of the University of California
          ("Regents").   According to  the terms of the agreement, the Company
          is required  to remit royalties based upon the greater of minimum of
          royalties or  a  percentage  of  product  sales  and  a  portion  of
          sublicensing income, as defined.  The agreement can be terminated by
          the Company  upon 90  days notice  or by  Regents in  the event  the
          Company fails  to perform, which includes the achievement of certain
          defined milestones;  otherwise the  agreement  terminates  upon  the
          lapse of  Regents' patent  regarding the licensed technology.  Early
          termination of the agreement could have a material adverse effect on
          the business  of the  Company.   Although the Company intends to use
          its best  efforts to  comply with  the terms of the agreement, there
          can be no assurances that the agreement will not be terminated.

      ii. Sloan-Kettering Institute for Cancer Research
          In November 1994, the Company (as licensee) entered into a worldwide
          exclusive licensing  agreement with  Sloan-Kettering  Institute  for
          Cancer Research  ("Sloan-Kettering") whereby  the  Company  has  the
          exclusive right  to use certain technology owned by Sloan-Kettering.
          Certain employees  of Sloan-Kettering are consultants to the Company
          (see Note  7(d)).   The Company is required to remit royalties based
          upon  the  greater  of  minimum  royalties,  as  defined,  or  as  a
          percentage of  sales of  any licensed  product, as defined ("Product
          Royalties"),  and   sublicense  income,  as  defined,  earned  under
          sublicenses granted by the Company in accordance with this licensing
          agreement ("Sublicense  Royalties").   In the  event that no Product
          Royalties or  Sublicense Royalties are due in a given calendar year,
          then a  defined percentage  of that  year's minimum  royalty will be
          creditable against  future Product Royalties or Sublicense Royalties
          due Sloan-Kettering.   The  licensing agreement may be terminated by
          Sloan-Kettering in  the event  that the  Company  fails  to  achieve
          certain  defined  objectives,  which  include  the  manufacture  and
          distribution of  a product  which uses  the licensed  technology, by
          2004, or  if the  Company fails to satisfy certain other contractual
          obligations ("Early  Termination"); otherwise  the  agreement  shall
          terminate either  upon  the  expiration  or  abandonment  of  Sloan-
          Kettering's patents on the technology licensed, or 15 years from the
          date of first commercial sale, as defined, whichever is later.  With
          regard to  Early Termination, Sloan-Kettering shall not unreasonably
          withhold its consent to revisions to the due dates for achieving the
          defined objectives under certain circumstances.  The Company has the
          right to  terminate the  agreement at  any time  upon 90  days prior
          written notice  ("Company Termination").   In  the  event  of  Early
          Termination or  Company Termination,  all licensing rights under the
          agreement would revert to Sloan-Kettering.  Early Termination of the
          license could  have a material adverse effect on the business of the
          Company.   Although the  Company intends  to use its best efforts to
          comply with the terms of the license, there can be no assurance that
          the licensing agreement will not be terminated.

     iii. Aquila Biopharmaceuticals, Inc.
          In August 1995, the Company (as licensee) entered into a license and
          supply    agreement    (the    "L&S    Agreement")    with    Aquila
          Biopharmaceuticals, Inc.  ("Aquila").   Under the  terms of  the L&S
          Agreement, the Company obtained a coexclusive license to use certain
          technology and  a right  to purchase  QS-21 adjuvant (the "Product")
          from Aquila  for use  in  the  Company's  research  and  development
          activities.   In consideration  for the  license, the Company paid a
          nonrefundable,  noncreditable   license  fee   and   issued   45,000
          restricted  shares   of  the  Company's  Common  Stock  ("Restricted
          Shares") to  Aquila.  The Restricted Shares are nontransferable with
          this restriction  lapsing upon  the Company's achievement of certain
          milestones ("L&S  Milestones"), as  defined.   In the event that any
          one or  more L&S  Milestones do not occur, the underlying Restricted
          Shares would  be returned  to the Company.  As of December 31, 1998,
          the restrictions on 11,250 shares of common stock have lapsed.   The
          fair value of the Restricted Shares, combined with the noncreditable
          license fee,  were expensed during 1995 as research and development.
          In addition,  the Company  will be required to remit royalties based
          upon the  net sales  of products  sold using the licensed technology
          ("Licensed Products")  and a  defined percentage  of any  sublicense
          fees and  royalties payable  to the Company with respect to Licensed
          Products.   The L&S  Agreement may  be terminated  by Aquila  in the
          event that  the Company fails to achieve certain defined objectives,
          which  include  the  manufacture  and  distribution  of  a  Licensed
          Product, by  2004 ("Early Termination"); otherwise the L&S Agreement
          shall terminate  upon the  expiration of  Aquila's  patents  on  the
          technology licensed.  With regard to Early Termination, Aquila shall
          not unreasonably  withhold its consent to revisions to the due dates
          for achieving  the L&S  Milestones under certain circumstances.  The
          Company has  the right  to terminate  the L&S  Agreement at any time
          upon 90  days  prior  written  notice  ("Company  Termination"),  as
          defined.   In the event of Early Termination or Company Termination,
          all licensing  rights under  the agreement  would revert  to Aquila.
          Early termination of the L&S Agreement would have a material adverse
          effect on the business of the Company.  Although the Company intends
          to use  its best  efforts to  comply  with  the  terms  of  the  L&S
          Agreement, there  can be no assurance that the agreement will not be
          terminated.

      iv. Bristol-Myers Squibb Company
          In July  1997, the  Company and Bristol-Myers Squibb Company ("BMS")
          entered into  a Joint  Development and Master License Agreement (the
          "BMS License  Agreement") under  which  BMS  obtained  an  exclusive
          worldwide license  to manufacture,  use and  sell products resulting
          from development  of  the  Company's  products  related  to  certain
          therapeutic cancer vaccines (the "Cancer Vaccines").  Upon execution
          of the  agreement, BMS  made non-refundable  cash payments  of  $9.5
          million, as  reimbursement for  expenses previously  incurred by the
          Company in the development of the Cancer Vaccines, $2.0 million as a
          licensing fee and approximately $1.8 million as reimbursement of the
          Company's  budgeted   clinical  development  costs  for  the  Cancer
          Vaccines for  the period  April 15, 1997 through September 30, 1997.
          In addition, BMS is obligated to make future non-refundable payments
          as defined  upon the  achievement of  specified milestones  and  pay
          royalties on  any product  sales.  BMS is also required to subsidize
          ongoing  development,   clinical  trials   and  regulatory   filings
          ("Development Costs")  conducted  by  the  Company  on  a  time  and
          material basis  related to  the Cancer  Vaccines.   BMS's funding of
          future Development  Costs are  refundable by the Company only to the
          extent that  the Company  receives such funding in advance and fails
          to expend  such amounts  for their  intended purposes.   The Company
          recognized as  revenue the  reimbursement of  prior expenses and the
          licensing fee  upon receipt  of the  funds.   The Company recognizes
          revenue for  the funding of Development Costs on a pro rata basis as
          the related expenses are incurred.

          The BMS  License Agreement  and  related  sublicenses  terminate  at
          various times,  generally upon  the expiration or abandonment of the
          related patents.   The  agreements can  also be terminated by either
          party upon  a material  uncured breach  by the other party.  BMS has
          the further  right to terminate the BMS License Agreement (including
          its funding  and milestone  obligations) as  to  specified  licensed
          products at specified times.

       v. Hoffmann-LaRoche
          On December  23, 1997  (the "Effective  Date"), the  Company entered
          into an  agreement (the  "Roche Agreement")  to conduct  a  research
          collaboration with  F. Hoffmann-LaRoche  Ltd. and  Hoffmann-LaRoche,
          Inc. (collectively "Roche") to identify novel HIV therapeutics.  The
          Roche Agreement  grants to  Roche an  exclusive worldwide license to
          use certain of the Company's intellectual property rights related to
          HIV to  develop, make,  use and  sell products  resulting  from  the
          collaboration.

          The terms of the Roche Agreement require Roche to pay the Company an
          upfront fee  and defined  amounts annually  for the first year, with
          annual adjustments thereafter, for the funding of research conducted
          by the  Company.   Roche's  annual  payment  is  made  quarterly  in
          advance.  Such funding will continue for a minimum of two years from
          the Effective  Date.   In addition,  the Company  will receive  non-
          refundable  milestone   payments  and   royalty  payments  based  on
          achievement of certain events and a percentage of worldwide sales of
          products  developed  from  the  collaboration,  respectively.    The
          Company recognizes  as revenue  milestone  payments  as  earned  and
          research reimbursements  on a pro rata basis as the underlying costs
          are incurred.   The  collaboration has a term of three years and may
          be extended  by mutual  agreement.  The Roche Agreement shall remain
          in force  until the  expiration of  all obligations to pay royalties
          pursuant to  any licenses  specified by  the Roche Agreement.  Roche
          may terminate  the Roche  Agreement at  any time  with prior written
          notice, at  which time  the license  granted  by  the  Company  will
          terminate.   Either party  may terminate  the Roche Agreement if the
          other party  defaults on  its obligations  and such  default is  not
          cured within sixty days of written notice of such default.

Notes to Financial Statements, Continued


        In connection with all the agreements discussed above, the Company has
        recognized research  and development  expenses, including  transaction
        costs, totaling  approximately $170,500,  $1,901,000 and  $550,000 for
        the years  ended December 31, 1996, 1997 and 1998, respectively.  Such
        expenses include  the fair  value of the Restricted Shares and 120,000
        shares of  Common Stock  issued in  July 1997.   In  addition,  as  of
        December 31,  1998, remaining  payments associated with milestones and
        defined  objectives   with  respect  to  the  above  agreements  total
        $650,000.    Future  annual  minimum  royalties  under  the  licensing
        agreements described in (i) through (iii) above are not significant.

     d. Consulting Agreements

        As part  of the  Company's research  and development efforts it enters
        into  consulting   agreements  with  external  scientific  specialists
        ("Scientists") and others.  These Agreements contain varying terms and
        provisions including  fees to be paid by the Company and royalties, in
        the event of future sales, and milestone payments, upon achievement of
        defined events,  payable to  the Company.  Certain Scientists, some of
        who are  members of  the Company's  Scientific  Advisory  Board,  have
        purchased Common  Stock or received stock options which are subject to
        vesting provisions,  as defined.   The Company has recognized expenses
        with regards  to these  consulting agreements  totaling  approximately
        $268,000, $971,000,  and $482,000  for the  years ended  December  31,
        1996, 1997  and 1998,  respectively.   Such expenses  include the fair
        value  of  stock  options  of  approximately  $112,000,  $772,000  and
        $329,000 for  the  years  ended  December 31,  1996,  1997  and  1998,
        respectively.


8.   Stock Option and Employee Stock Purchase Plans:

     The Company  adopted three  stock option  plans, the  Non-Qualified Stock
     Option Plan,  the Stock  Option Plan and the Amended Stock Incentive Plan
     (individually the  "89 Plan,"  "93 Plan"  and "96 Plan," respectively, or
     collectively, the  "Plans").   Under the  89 Plan, the 93 Plan and the 96
     Plan as  amended, a  maximum of  375,000, 750,000 and 2,000,000 shares of
     Common Stock,  respectively,  are  available  for  awards  to  employees,
     consultants, directors  and other  individuals who render services to the
     Company (collectively,  "Optionees").   The Plans  contain certain  anti-
     dilution provisions  in the  event of  a stock  split, stock  dividend or
     other capital adjustment as defined.  The 89 Plan and 93 Plan provide for
     the Board,  or the  Compensation Committee ("Committee") of the Board, to
     grant stock  options to  Optionees and  to determine  the exercise price,
     vesting term  and expiration date.  The 96 Plan provides for the Board or
     Committee to grant to Optionees stock options, stock appreciation rights,
     restricted  stock   performance  awards  or  phantom  stock,  as  defined
     (collectively "Awards").   The Committee will also determine the term and
     vesting of  the Award  and the Committee may in its discretion accelerate
     the vesting  of an  Award at  any time.   Options granted under the Plans
     generally vest  pro rata  over five to ten year periods and have terms of
     ten to  twenty years.   Except  as noted  below, the  exercise  price  of
     outstanding awards  was equal  to the  fair value of the Company's Common
     Stock on  the dates  of grant.   Under  the 89  Plan, for a period of ten
     years  following   the  termination  for  any  reason  of  an  Optionee's
     employment or  active involvement  with the Company, as determined by the
     Board, the  Company has  the right  to repurchase  any or  all shares  of
     Common Stock  held by  the Optionee  and/or any  or all of the vested but
     unexercised portion  of any option granted to such Optionee at a purchase
     price defined  by the 89 Plan.  The 89 Plan terminated in April, 1994 and
     the 93 Plan and the 96 Plan will terminate in December, 2003 and October,
     2006, respectively;  however, options  granted before  termination of the
     Plans will continue under the respective Plans until exercised, cancelled
     or expired.

     1997 and 1998 are summarized as follows:

       (1) Includes 216,225 options repriced, as discussed below
       (2) For all  options granted  in 1996  and 1998  and 2,100  in 1997, the
           option exercise price   equaled the  fair  value  of  the  Company's
           common stock  on the date of grant.  For 1997, 845,900 options  were
           granted, with  an exercise  price below the fair market value of the
           Company's common stock on the date of grant.

     As of  December 31,  1996, 1997  and 1998,  488,553, 818,586, and 858,464
     options with  weighted average exercise prices of $3.59, $3.92 and $4.01,
     respectively, were exercisable under the Plans.

     As of  December 31, 1998, shares available for future grants under the 93
     Plan and the 96 Plan amounted to 35,362 and 560,700, respectively.

     The Company,  during  1997,  granted  520,900  stock  options  (including
     216,225 options  repriced as  discussed  below)  to  employees,  with  an
     average exercise price of $4.00, which was below the estimated fair value
     of the  Common Stock  on the  date of grant.  Accordingly, the Company is
     recognizing compensation  expense on a pro rata basis over the respective
     options' vesting  periods, of  one to  five  years,  for  the  difference
     between the  estimated fair  value of  the Common  Stock on  the date the
     option was  granted and  the exercise price ("Unamortized Compensation").
     The Unamortized  Compensation as  of December  31, 1997 and 1998 has been
     included within  stockholders equity.   For  the years ended December 31,
     1997 and  1998, the  annual amortization  of  Unearned  Compensation  for
     employees totaled  $322,296 and  $314,902.   As of  December 31, 1998 the
     unamortized  portion  of  Unearned  Compensation  for  employees  totaled
     $417,502.

     The Company  since its  inception has  granted an  aggregate of 1,082,000
     options with a weighted-average exercise price of $3.86 to consultants in
     consideration for  services.   The fair values of these options have been
     included as Unearned Compensation and are being amortized as compensation
     expense on  a pro  rata basis  over the  service period ranging from four
     years to ten years.  For the years ended December 31, 1996, 1997 and 1998
     the annual  amortization of Unearned Compensation for consultants totaled
     $128,963,  $778,358  and  $335,461,  respectively.    The  above  amounts
     included the  fair value  of  stock  options  issued  to  consultants  as
     discussed in Note 7(d).  As of December 31, 1998, the unamortized portion
     of Unearned Compensation for consultants totaled $693,516.

     On April 1, 1997, the exercise price of 216,225 options granted under the
     Plans, having  exercise prices in excess of $4.00 per share, were reduced
     to $4.00  per share.  The exercise price of the repriced options was less
     than the  fair value  of the  underlying stock  on the date of repricing.
     Accordingly, the  Company is  recognizing compensation  expense on  a pro
     rata basis  over the respective remaining options' vesting periods of one
     to five  years for the difference between the estimated fair value of the
     Common Stock  on the  date the  option was repriced and $4.00.  All other
     aspects of the options remain unchanged.

     During 1993,  the Company  adopted an  Executive Stock  Option Plan  (the
     "Executive Plan"),  under which  a maximum  of 750,000  shares of  Common
     Stock, adjusted  for stock  splits, stock  dividends, and  other  capital
     adjustments, as  defined, are  available for stock option awards.  Awards
     issued under  the Executive  Plan may  qualify as incentive stock options
     ("ISOs"), as  defined by  the Internal Revenue Code, or may be granted as
     non-qualified stock  options.   Under the  Executive Plan,  the Board may
     award options  to senior  executive employees (including officers who may
     be members  of the Board) of the Company, as defined.  The Executive Plan
     will terminate  on December 15,  2003; however, any option outstanding as
     of the  termination date  shall  remain  outstanding  until  such  option
     expires in accordance with the terms of the respective grant.

     During December  1993, the Board awarded a total of 750,000 stock options
     under the  Executive Plan  to one  officer, of  which 664,774  were  non-
     qualified options  ("NQOs") and 85,226 were ISOs.  The NQOs and ISOs have
     a term  of ten  years and entitle the officer to purchase an equal number
     of shares  of Common  Stock at  prices of  $5.33  and  $5.87  per  share,
     respectively, which  represented the estimated fair market value and 110%
     of the  estimated fair  market value of the Company's Common Stock at the
     date of  grant, as  determined by the Board of Directors.  375,000 of the
     options vest  pro rata  over a  period of  four years, with the remaining
     375,000 options  vesting in  full on the tenth anniversary of the date of
     grant; however,  vesting with respect to the options vesting on the tenth
     anniversary will  be accelerated in the event of the effective date of an
     initial public offering of the Company's Common Stock that yields certain
     gross per share amounts, as defined, or immediately before the closing of
     an acquisition  of the  Company.   As the result of the Company's IPO and
     subsequent increase  in the  fair market  value of  the Company's  Common
     Stock, 300,000  options vested.   During  1998, 275,226  options, with  a
     weighted-average exercise price of $5.50 per share, were exercised.

     As of  December 31,  1996, 1997  and 1998,  300,000, 450,000  and 399,774
     options with  weighted-average exercise prices of $5.45, $5.43 and $5.33,
     respectively, were exercisable under the Executive Plan.

     On May  1, 1998,  the Company  adopted two  employee stock purchase plans
     (the "Purchase  Plans"), the  1998  Employee  Stock  Purchase  Plan  (the
     "Qualified Plan)"  and the 1998 Non-Qualified Employee Purchase Plan (the
     "Non-Qualified").   The Purchase  Plans provide  for  the  grant  to  all
     employees of options to use up to 25% of their quarterly compensation, as
     such percentage is determined by the Board of Directors prior to the date
     of grant,  to purchase  shares of  the Common  Stock at a price per share
     equal to  the lesser  of the fair market value of the Common Stock on the
     date of  grant or  85% of  the fair market value on the date of exercise.
     Options are granted automatically on the first day of each fiscal quarter
     and expire  six months  after the  date of grants.  The Qualified Plan is
     not available  for employees  owning more than 5% of the Common Stock and
     imposes  certain  other  quarterly  limitations  on  the  option  grants.
     Options under the Non-Qualified Plan are granted to the extent the option
     grants are  restricted under  the Qualified Plan.  The Qualified and Non-
     Qualified Plans  provide for  the issuance  of up  to 150,000  and 50,000
     shares of Common Stock, respectively.

     Purchases of  Common Stock  during the  year ended  December 31, 1998 are

     At December  31, 1998,  shares reserved  for future  purchases under  the
     Qualified and Non-Qualified Plans were 146,506 and 50,000, respectively.

     The following  table summarizes  the pro  forma operating  results of the
     Company had  compensation costs for the Plans, the Executive Plan and the
     Purchase Plans  been determined  in accordance  with the fair value based
     method of  accounting for  stock based compensation as prescribed by SFAS
     No. 123.   Since  option grants  awarded during  1996, 1997 and 1998 vest
     over several years and additional awards are expected to be issued in the
     future,  the  pro  forma  results  shown  below  are  not  likely  to  be
     representative of  the effects  on future years of the application of the
     fair value based method.

     For the  purpose of  the above  pro forma  calculation, the fair value of
     each option  granted was  estimated on the date of grant using the Black-
     Scholes option  pricing model.   The  weighted-average fair  value of the
     options granted  during 1996,  1997 and  1998 was  $4.60, $3.91 and $6.87
     respectively.   The following assumptions were used in computing the fair
     value of option grants:  expected volatility  of 81% in 1996 and 1997 and
     71% in 1998; expected lives of 5 years after vesting; zero dividend yield
     and  weighted-average  risk-free interest rates of 6.0% in 1996, 6.72% in
     1997 and 4.45% in 1998.

9.   Employee Savings Plan:

     The Company,  during 1993,  adopted the  provisions of  the  amended  and
     restated Progenics Pharmaceuticals 401(k) Plan (the "Amended Plan").  The
     terms of  the Amended Plan, among other things, allow eligible employees,
     as defined,  to participate in the Amended Plan by electing to contribute
     to the Amended Plan a percentage of their compensation to be set aside to
     pay their future retirement benefits, as defined.  The Company has agreed
     to match  25% of  up to  the  first  8%  of  compensation  that  eligible
     employees contribute  to the  Amended Plan, as defined.  In addition, the
     Company may also make a discretionary contribution, as defined, each year
     on behalf  of all  participants who are non-highly compensated employees,
     as defined.   The  Company made  matching contributions  of approximately
     $10,000, $9,000  and $27,000  to the  Amended Plan  for the  years  ended
     December 31, 1996, 1997 and 1998, respectively.

     

10.  Income Taxes:

     There is  no tax  provision for  the year  ended December 31, 1998 as the
     Company was  able  to  utilize  net  operating  loss  carryforwards  that
     previously had  been fully  provided for.  The effects of the alternative
     minimum tax on the 1998 provision were immaterial.

     The tax  provision for the year ended December 31, 1997 has been computed
     based upon  the prevailing  federal and  state tax  rates, offset  by the
     utilization of  net operating  loss carryforwards to the extent permitted
     by the  alternative minimum tax rules of the federal and state tax codes.
     There is  no benefit for federal or state income taxes for the year ended
     December 31, 1996,  since the  Company has  incurred operating losses and
     has established  a valuation  allowance equal  to the  total deferred tax
     asset.

     The  differences   between  the  Company's  effective  income  tax  rate,
     (benefit) provision, and the Federal statutory rate is reconciled below:

     The tax  effect of  temporary differences,  net operating  losses and tax

     The Company  does not  recognize  deferred  tax  assets  considering  the
     history of  taxable losses  and the  uncertainty regarding  the Company's
     ability to  generate sufficient  taxable income  in the future to utilize
     these deferred tax assets.

     As of  December 31,  1998, the  Company has  available, for tax purposes,
     unused net  operating loss  carryforwards of  approximately $6.5  million
     which will  expire in  various years  from 2002  to 2013.   The Company's
     research and  experimental tax  credit carryforwards  expire  in  various
     years from  2003 to 2013.  In addition, the Company's alternative minimum
     tax credit can be carried forward indefinitely.  Future ownership changes
     may limit  the future  utilization of  these net  operating loss  and tax
     credit carryforwards as defined by the federal and state tax codes.


11.  Line of Credit:

     During March  1997 the  Company obtained a line of credit ("Line") from a
     bank.   The terms  of the Line provide for the Company to borrow up to $2
     million.  Outstanding borrowings accrue interest, payable monthly, at the
     bank's prime  rate of  interest.  The Line expired on July 31, 1997.  The
     repayment of  the Line  was guaranteed by two affiliates of a stockholder
     of the Company ("Affiliates").

     In consideration for the guarantee of the Line, the Company issued 70,000
     warrants to  the Affiliates.  Such warrants vested immediately and expire
     after five  years.   The exercise  price was  determined to  be $4.00 per
     share in  November  1997  upon  completion  of  the  Company's  IPO.  The
     aggregate fair value of the warrants totaled $227,867, which was expensed
     during the year ended December 31, 1997.

12.  Net (Loss)  Income Per Share:

     The Company's  basic net  (loss)  income  per  share  amounts  have  been
     computed by  dividing net (loss) income by the weighted-average number of
     common shares outstanding during the period.  For the year ended December
     31, 1996,  the Company  reported net  losses and, therefore, common stock
     equivalents were  not included since such inclusion would have been anti-
     dilutive.   For the  years ended  December 31, 1997 and 1998, the Company
     reported net  income and,  therefore, all  common stock equivalents, with
     exercise prices  less than the average fair market value of the Company's
     Common Stock  for the  year, have  been included  in the  calculation, as
     follows:

pursuant to Section 8.

          2.3  Provided MADDON  is not  in default  under this Agreement at the

          4.   REMUNERATION.

          4.1  The Corporation will pay MADDON, for all services to be rendered

under this  Agreement, an  annual salary ("Salary"), payable in accordance with

the normal  payroll  policy  of  the  Corporation,  of  Four  Hundred  Thousand

($400,000) Dollars, adjusted as hereinafter provided, for the Term.

          4.2  Each year  on the anniversary date of this Agreement, the annual

Salary then in effect shall be multiplied by 103% (or such higher percentage as

the Board  shall determine in its sole discretion) and the product shall be the

adjusted Salary  for the  next succeeding  twelve (12)  month period during the

Term.

          4.3  During the  Term of this Agreement, MADDON may receive an annual

bonus  payment   reflecting  his   contribution  to  the  Corporation  and  the

Corporation's results in an amount the Board determines appropriate in its sole

discretion.

          4.4  This Agreement will not be deemed abrogated or terminated if the

Corporation, in its discretion, determines to increase the Salary of MADDON for

any period  of  time,  or  if  MADDON  accepts  an  increase;  but,  except  as

specifically  provided  in  this  Agreement,  the  Corporation  shall  have  no

obligation to make any increase in the Salary.  Any increase in MADDON's Salary

by the  Corporation shall be incorporated into his annual Salary then in effect

     shall be as follows:

               (1)  If the  Average Price is less than Fifteen Dollars ($15.00)
          per share,  then no  portion of  the Valuation  Based Options vesting
          shall accelerate or may be exercised.

               (2)  If either  (i) during  the  period  from  the  date  hereof

          equal to  or greater than Thirty Dollars ($30.00) per share, then the
          vesting of Valuation Based Options for 75,000 Shares shall accelerate
          and may be exercised at any time thereafter.

               (3)  If either  (i) during  the  period  from  the  date  hereof

                                       5
<PAGE>
          Valuation  Based  Options  for  an  additional  75,000  Shares  shall
          accelerate and may be exercised at any time thereafter.

               (4)  If either  (i) during  the  period  from  the  date  hereof
          through December  21, 2001,  the Average Price is equal to or greater
          than Twenty-four Dollars ($24.00) per share or (ii) during the period
          from December 22, 2001 through November 21, 2008 the Average Price is
          equal to or greater than Thirty Dollars ($30.00), then the vesting of
          Valuation  Based  Options  for  an  additional  75,000  Shares  shall
          accelerate and may be exercised at any time thereafter.

          b.   "Average Price"  shall mean  the thirty (30) trading day average
     market price of one share of Common Stock, determined by the last reported
     sales price  of the  Common Stock  on the  NASDAQ National Market (or such
     other exchange as may be the principal exchange on which the Corporation=s
     Common Stock is listed) on each trading day during such thirty trading day
     period that any such sale shall have been reported.


               5.4  General Terms  of Options.  The Traditional Options and the

Valuation Based  Options (collectively, the "Options") are set forth in written

stock   option    agreements   being   executed   and   delivered   to   MADDON

contemporaneously with  the execution  and delivery  of this  Agreement.    The

option agreements  provide that  in the  event MADDON  wishes to  exercise  the

exercisable portion  of an  option, MADDON  shall send  written notice  to  the

Corporation specifying a date (not later than twenty (20) business days and not

earlier than the next business day following the date such notice is given) for

the closing of such purchase.  The exercise price of the Options may be paid by

MADDON in cash, by the delivery of promissory note or by the delivery of Common

Stock of  the Corporation.   In  the latter  case the  fair market value of the

Common Stock  delivered, determined  by reference  to the  last reported  sales

price of the Common Stock on the NASDAQ National Market (or such other exchange

as may  be the  principal exchange  on which  the Corporation=s Common stock is

listed) on  the last day prior to such exercise on which trading occurred, will

be applied to the exercise price.

               5.5  Acceleration of Exercise Schedule.  All  Options shall vest

and become  fully exercisable  immediately upon  any AChange  in Control@.  For

purposes of this Agreement, a AChange in Control@ shall mean:
               (i)  a change  in the  composition of the Board such that during
     any period  of two  consecutive years, individuals who at the beginning of
     such period  constitute the  Board, and  any new  director (other  than  a
     director designated by a person who has entered into an agreement with the


                                       6
<PAGE>
     Corporation to  effect a  transaction described in clause (ii) or (iii) of
     this paragraph)  whose election by the Board or nomination for election by
     the Corporation=s  stockholders was  approved by  a vote  of at least two-
     thirds of  the directors then still in office who either were directors at
     the beginning  of the  period or whose election or nomination for election
     was previously  so approved, cease for any reason to constitute at least a
     majority of the members thereof;

               (ii) the approval  by the  stockholders of  the Corporation of a
     merger, consolidation,  reorganization or  similar corporate  transaction,
     whether or  not the  Corporation is  the  surviving  corporation  in  such
     transaction, in  which outstanding  shares of  Common Stock  are converted
     into (A)  shares of stock of another company, other than a conversion into
     shares of  voting common  stock of the successor corporation (or a holding
     company thereof)  representing more  than 50%  of the  voting power of all
     capital  stock   thereof  outstanding  immediately  after  the  merger  or
     consolidation, or  (B) other  securities (of  either  the  Corporation  or
     another company) or cash or other property; or

               (iii) the approval by the stockholders of the Corporation of (A)
     the sale or other disposition of all or substantially all of the assets of
     the Corporation,  or (B)  a complete  liquidation or  dissolution  of  the
     Corporation.


          Except as may be required under Section 422A of the Code with respect

to ISOs,  neither the Traditional Options nor the Valuation Based Options shall

be subject  to any  limitations under any stock option plan or otherwise on the

post-employment period  during which  such options  may be  exercised or to any

repurchase rights by the Corporation, except as provided in Section 8.2 hereof.

          6.   EMPLOYEE BENEFITS.

          During the  term of  this Agreement,  MADDON  shall  be  eligible  to

participate in  all employee  benefit plans  and programs of the Corporation in

which other  senior executives  of the  Corporation are eligible to participate

from time  to time,  including,  without  limitation,  any  qualified  or  non-

qualified pension,  401(k), profit  sharing  and  savings  plans,  any  welfare

benefit plans  (including, without limitation, medical, dental and health plans

and disability  and group  life insurance coverages), subject to and on a basis

consistent with  the terms, conditions and overall administration of such plans

and programs.   MADDON  shall be  entitled to  participate in  such  plans  and

programs on  terms no  less favorable  to MADDON  than those  on  which  senior

executives of  the Corporation  generally participate.   Without  limiting  the



                                       7
<PAGE>
generality of  the foregoing,  the Corporation  shall provide  MADDON with such

long-term  disability  and  life  insurance  benefits  as  are  made  generally

available to senior executives of the Corporation.

          During the  term of  this Agreement, MADDON shall be entitled to such

fringe benefits  and perquisites  as are  made generally  available  to  senior

executives  of  the  Corporation  from  time  to  time.    Notwithstanding  the

foregoing, in  each calendar  year of  the Term MADDON shall accrue four weeks=

paid vacation.   In each calendar year commencing with the calendar year ending

December 31,  1999, MADDON  may carry  over and  use up  to two  weeks of  such

vacation during the next calendar year.

          MADDON  acknowledges   and  agrees  that  the  Corporation  does  not

guarantee the  adoption or  continuance of any particular employee benefit plan

or program  or other  fringe benefit  during the  terms of  this Agreement, and

participation by  MADDON in  any such  plan or  program shall be subject to the

rules and regulations applicable thereto.

          7.   REIMBURSEMENT OF EXPENSES.

          The Corporation  shall  provide  MADDON  with  reimbursement  of  all

reasonable travel  (including private car service commuting expenses, or in the

alternative,  car   leasing  expenses)   and  other   business   expenses   and

disbursements incurred  by MADDON  in the  performance of his duties under this

Agreement, upon  proper accounting  in accordance with the Corporation=s normal

practices and procedures for reimbursement of business expenses.

          8.   TERMINATION.

          8.1  The Term  and this  Agreement, except those provisions specified

to survive  termination, shall  terminate before  the expiration date set forth

above in Section 2 on the occurrence of the earlier of the following:

               8.1.1  On the dissolution of the Corporation;

               8.1.2  On the  death or  disability of MADDON.  Disability shall

Hundred Twenty  (120) days  consecutively or  One  Hundred  Eighty  (180)  days


                                       8
<PAGE>
cumulatively during  any twelve  (12) month period of the Term, services of the

character contemplated by this Agreement;

               8.1.3  On the  dismissal of  MADDON for  good cause shown, which

shall mean such cause as the courts of the State of New York (including federal

courts) have  determined to  be justifiable cause for termination of employment

including the  continual failure  by MADDON to perform substantially his duties

with the Corporation (other than any such failure resulting from incapacity due

to physical  or mental  illness) after  a demand for substantial performance is

delivered to  MADDON by  the Board,  conviction of  a  felony  involving  moral

turpitude, habitual  drunkenness, excessive  absenteeism not  related  to  sick

leave or  vacations (but  only after  notice  from  the  Board  followed  by  a

repetition of  such excessive  absenteeism), dishonesty directly and materially

injurious to  the Corporation,  or continuous conflict of interest after notice

in writing from the Board;

               8.1.4  On the  dismissal of  MADDON without  cause (that is, for

any reason  the Corporation  shall determine other than for good cause shown or

death or disability); and

               8.1.5  On the resignation of MADDON.

          8.2  Upon  termination   of  the  Term  and  this  Agreement  at  the

expiration of  the Term  pursuant to Section 2, MADDON shall (i) be entitled to

receive any  amounts from  the Corporation then due but unpaid, prorated to the

date of  termination, together  with such annual bonus in respect of the period

from the  end of  the period in respect of which the last annual bonus was paid

to such  date of  termination, as  the Board determines appropriate in its sole

discretion as  contemplated by  Section 4.3  (an AEnding Bonus@), and (ii) have

the right  to exercise  the Options  granted pursuant  to Section 5  hereof  in

accordance with  Section 5 hereof,  except that  if MADDON=s  employment by the

Corporation shall  cease for  any reason  upon the  termination of  the Term or

          9.   COVENANT NOT TO COMPETE AND NON-DISCLOSURE OF

               CONFIDENTIAL INFORMATION.

          9.1  During or  after the  term of  this  Agreement  and/or  MADDON's

employment by the Corporation, MADDON shall not without the Corporation's prior

written consent  use or  disclose any  "Proprietary Information" (as defined in

Section 10.1) or any other confidential information relating to the Corporation

(including, but  not limited to, data on which patents have been applied for or

issued or  other proprietary  intellectual property,  customer lists, financial

information, sales  and marketing  data), or  its business, obtained during the

course of his employment.

          9.2  MADDON shall  not during the Term hereof and for a period of Two

(2) years  after the expiration or earlier termination of the Term, directly or

indirectly, own,  manage, operate, or control, any business in competition with

or similar  to the  type of business conducted by the Corporation, and will not

render services,  directly or indirectly, to any "Conflicting Organization" (as


                                      11
<PAGE>
hereinafter defined).  The foregoing shall not apply to the ownership by MADDON

of less  than  One  percent  (1%)  of  the  securities  of  a  publicly  traded

organization.   "Conflicting Organization"  means any  person  or  organization

engaged in  or about  to become  engaged in servicing, production, marketing or

selling  of,  a  "Conflicting  Product"  (as  hereinafter  defined);  provided,

Conflicting Product.   "Conflicting  Product" means  any product,  process,  or

service, in existence or under development, of any person or organization other

than the  Corporation which  resembles or  competes with a product, process, or

service of  the Corporation,  in existence  or under development.  In the event

that the  Corporation  terminates  MADDON's  employment  under  this  Agreement

without cause during the Term hereof or if MADDON terminates his employment for

Good Reason,  MADDON's obligation  under the  foregoing with  respect  to  non-

competition with  the Corporation  for a  period of  Two (2)  years after  such

termination shall no longer be applicable.

          9.3  During and  for a  period of  three years after the Term of this

Agreement and/or  MADDON's employment  by the  Corporation,  MADDON  shall  not

solicit or  induce any employees of the Corporation to leave the Corporation to

work for  any entity or person engaged in the same business as the Corporation,

either directly or indirectly.

          10.  PROPRIETARY INFORMATION.

          10.1 MADDON understands  that  the  Corporation  possesses  and  will

continue  to  possess  "Proprietary  Information"  (as  defined  below)  and/or

"Inventions"  (as  defined  below)  that  have  been  created,  discovered,  or

developed, or have otherwise become known to the Corporation.

               10.1.1  For purposes  of this  Agreement, particularly  for this

Section 10,  "Proprietary Information"  shall include,  but not  be limited to,

trade  secrets,   processes,  formulae,   data  and   know-how,   improvements,


                                      12
<PAGE>
"Inventions" (as  defined  below),  techniques,  marketing  plans,  strategies,

forecasts  and   customer  lists,  including  without  limitation,  information

created, discovered,  developed or made known by MADDON and within the scope of

this Agreement  or to  MADDON during  the period  of  or  arising  out  of  his

retention by  the Corporation,  and/or  in  which  property  rights  have  been

assigned or  otherwise conveyed  to  the  Corporation,  which  information  has

commercial value in the business in which the Corporation is engaged.

              10.1.2  For  purposes of  this Agreement,  particularly for  this

Section 10,  "Inventions" shall  mean any  improvements, inventions,  formulae,

processes, techniques,  know-how and  data, whether  or not patentable, made or

conceived or  reduced to practice or learned by MADDON, either alone or jointly

with others,  during the period of his employment (whether or not during normal

working hours),  together with all patent applications, patents, copyrights and

reissues thereof  that may  at any  time  be  granted  for  or  upon  any  such

improvements, inventions,  formulae, processes,  techniques, know-how  or data,

and/or during  the twelve  (12) months immediately following termination of his

employment which:

                    (a)  are within  the scope of the duties to be performed by

MADDON under this Agreement and are related to or useful in the business of the

Corporation, or

                    (b)  result from  tasks assigned MADDON by the Corporation,

or

                    (c)  are funded by the Corporation, or

                    (d)  result  from   use  of   premises  owned,   leased  or

contracted for by the Corporation.

          10.2  In consideration  of his  employment by the Corporation and the

compensation received by MADDON from the Corporation, MADDON agrees as follows:

               10.2.1  All Proprietary  Information including,  but not limited

to, all  "Inventions" as  defined above,  shall be  the sole  property  of  the




                                      13
<PAGE>
Corporation and its assigns and MADDON assigns to the Corporation any rights he

may have or acquire in all Proprietary Information.

               10.2.2  All documents,  data, records, apparatus, equipment, and

other physical  property, whether or not pertaining to Proprietary Information,

furnished to  MADDON by  the Corporation  or produced  by MADDON  or others  in

connection with  his employment,  shall be  and remain the sole property of the

Corporation and  shall be  returned promptly  to the  Corporation as  and  when

requested by  the Corporation.   Should  the Corporation not so request, MADDON

shall return  and deliver  all such property upon termination of his employment

with the  Corporation for any reason and MADDON will not take with him any such

property or  any reproduction  of such  property upon such termination but this

shall not  apply to  MADDON's personal  diaries and papers provided same do not

contain information relating to Proprietary Information or Inventions.

               10.2.3  MADDON will  promptly disclose  all  Inventions  to  the

Corporation, or  any persons designated by it.  Such disclosures shall continue

for One  (1) year  after termination of this Agreement with respect to anything

that would  be an  Invention if made, conceived, reduced to practice or learned

during the Term.

               10.2.4  The Inventions  shall become  and remain the property of

the Corporation,  whether or  not patent  applications are filed thereon.  Upon

request and  at the  expense of  the Corporation, MADDON shall make application

through the patent attorneys or agents of the Corporation for letters patent of

the United  States and  any and  all other  countries at  the discretion of the

Corporation on  the Inventions  and to  assign all  such  applications  to  the

Corporation or  its order  immediately, all  without additional payment, during

MADDON's period  of employment  by the  Corporation and  for one year after the

termination of  employment.   MADDON shall  give the Corporation, its attorneys

and  agents  all  reasonable  assistance  in  preparing  and  prosecuting  such

applications and,  on request  of the  Corporation, MADDON  shall  execute  all

papers and do all things that may be reasonably necessary to protect the rights


                                      14
<PAGE>
of the  Corporation and vest in it or its assigns the inventions, applications,

and letters patent herein contemplated.

          11.  RETURN OF DOCUMENTS.

          On the  expiration or  earlier termination  of the  Term or  MADDON's

resignation, discharge  or earlier departure from the Corporation, MADDON shall

promptly surrender  to the Corporation all of the Corporation's books, records,

documents and  customer lists  and/or other  of the  Corporation's materials or

records he  may have  in his  possession, including  but  not  limited  to  the

materials described in Section 10.2.2.

          12.  REMEDIES.

          12.1  MADDON agrees  that his  services are  of a special, unique and

extraordinary character,  that it  would be extremely difficult to replace such

services, and that, in the event of a breach or threatened breach of any of the

provisions of  this Agreement, the Corporation will not have an adequate remedy

at law.   Accordingly,  the Corporation  shall  be  entitled  to  enforce  such

provisions by means of injunctive relief as may be available to restrain MADDON

and  any   business,  firm,  partnership,  individual,  corporation  or  entity

participating in  such breach  or threatened  breach from  the violation of the

provisions hereof,  without  thereby  waiving  any  other  legal  or  equitable

remedies available  to the  Corporation.  Likewise, MADDON shall be entitled to

enforce the  provisions of  this Agreement by means of injunctive relief as may

be available  to restrain  the Corporation  from the  violation  or  threatened

violation of  the provisions hereof, without thereby waiving any other legal or

equitable remedies available to him.

          12.2  If any of the covenants contained in this Agreement or any part

thereof is held to be unenforceable because of the duration thereof or the area

or scope  covered thereby,  the parties hereby agree that the court making such

determination shall have the power to reduce the duration, area and/or scope of

such covenant so that in its reduced form, the covenant shall be enforceable.




                                      15
<PAGE>
          13.  TRANSFER AND ASSIGNMENT.

          This Agreement  will extend  to and  be binding  on MADDON, his legal

representatives,  heirs,   and  distributees,   and  on  the  Corporation,  its

successors and  assigns, and  the term  "Corporation" as used in this Agreement

will include such successors and assigns.

          14.  MODIFICATIONS.

parties have  made no  other agreements, representations or warranties relating

to the  subject matter  of this  Agreement.   No modification of this Agreement

will be valid unless made in writing and signed by the parties.

          16.  ADVERSE PUBLIC STATEMENTS AND DISCLOSURES.

          The parties hereto agree that at no time during or  subsequent to the

term of  this Agreement  will either  party  directly  or  indirectly  make  or

facilitate the  making of  any adverse  public statements  or disclosures  with

respect to the other (including, with respect to the Corporation, regarding its

business or securities or its Board, management or other personnel).

          17.  WAIVER AND BREACH.

          The waiver  or breach of any term or condition of this Agreement will

not be  deemed to  constitute the waiver of any other breach of the same or any

other term or condition.

          18.  GOVERNING LAW AND JURY TRIAL WAIVER.

          This Agreement  will be  governed by and construed in accordance with

the laws  of the  State of  New York  applicable to  contracts made  and to  be

performed entirely  within that  State.   In any  litigation based on any claim

hereunder, the parties hereto agree to waive trial by jury.
