ITEM 1--BUSINESS

INTRODUCTION

         Immunomedics,  Inc.  (the  "Company")  is a  biopharmaceutical  company
applying innovative proprietary  technology in antibody selection,  modification
and chemistry to the  development of products for the detection and treatment of
cancers and infectious diseases.  Integral to these products are highly specific
monoclonal antibodies designed to deliver radioisotopes, chemotherapeutic agents
or toxins to tumors and sites of infection.

         The Company is  developing a line of IN VIVO  imaging  products for the
detection  of various  cancers and  infectious  diseases.  In April,  1991,  the
Company  filed a Product  License  Application,  now called a Biologics  License
Application  ("BLA"),  to which a supplement was filed in June,  1993,  with the
U.S. Food and Drug  Administration  ("FDA") seeking  approval to manufacture and
market,  in the United  States,  the Company's  proprietary  IN VIVO  colorectal
cancer imaging product, CEA-Scan(R). On June 28, 1996, the FDA licensed CEA-Scan
for use with other standard diagnostic modalities for the detection of recurrent
and/or metastatic  colorectal cancer. In March, 1992, the Company filed with the
Committee for Proprietary  Medicinal  Products ("CPMP") to market the product in
Europe. On October 4, 1996, the Company was granted  marketing  authorization by
the European  Commission for use of CEA-Scan in the 15 countries  comprising the
European Union for the same  indication as approved in the United States.  Phase
III clinical trials of CEA-Scan for the detection of lung cancer are continuing,
and the Company is in discussion with both the FDA and CPMP to evaluate Phase II
clinical  trial data for the detection of breast cancer.  However,  no assurance
can be given as to if,  or when,  final  regulatory  approvals  for any of these
additional indications for CEA-Scan may be forthcoming.  In February,  1992, the
Company filed with the Health  Protection  Branch ("HPB") to market  CEA-Scan in
Canada.  On September 16, 1997, the Company received a notice of compliance from
the HPB  permitting it to market  CEA-Scan in Canada for  colorectal  cancer for
recurrent and metastatic colorectal cancer.

         On February 14, 1997,  the Company was granted  regulatory  approval by
the European  Commission to market  LeukoScan(R),  an IN VIVO infectious disease
diagnostic  imaging  product,  in all 15  countries  which  are  members  of the
European  Union,  for  the  detection  and  diagnosis  of  osteomyelitis   (bone
infection)  in long bones and in diabetic foot ulcer  patients.  On December 19,
1996, the Company filed a BLA for LeukoScan with the FDA for the same indication
approved in Europe,  plus an additional  indication  for the diagnosis of acute,
atypical appendicitis.  The Company has also been pursuing the broadening of its
approval  for  LeukoScan in Europe to include the acute,  atypical  appendicitis
indication.  As with all regulatory filings, there can be no assurance that such
filings  will be approved by the FDA or by the  European  Commission.  Phase III
trials for  infected  prostheses  are  continuing,  and the Company is examining
other applications for the product.

                                       1
<PAGE>

         The  Company  has  developed  and  filed  an  Investigational  New Drug
application ("IND") for two other IN VIVO cancer imaging products:  AFP-Scan(TM)
for the detection  and  diagnosis of liver and germ cell  cancers,  currently in
Phase II clinical  trials,  and  LymphoScan(TM)  for  detection and diagnosis of
non-Hodgkin's  lymphomas,  currently in Phase III clinical trials (see "Clinical
Trial Programs").

         The  Company  also is applying  its  expertise  in antibody  selection,
modification  and  chemistry  to develop  therapeutic  products for cancer using
monoclonal  antibodies  labeled with radioisotopes or conjugated with drugs. The
Company  has been  conducting  a  multicenter  Phase  I/II  clinical  trial  for
LymphoCide(TM)   (formerly   ImmuRAIT-LL2),   a  non-Hodgkin's  B-cell  lymphoma
therapeutic product. This trial was designed to obtain knowledge about targeting
and dosing with the murine form of the monoclonal  antibody.  The Company is now
advancing the humanized form of LymphoCide  into Phase I/II clinical  trials and
is  discontinuing  trials  with  the  murine  form  (see  "IN  VIVO  Therapeutic
Products").

         In March,  1995,  the Company  entered  into a license  agreement  with
Mallinckrodt Medical B.V., pursuant to which Mallinckrodt Medical B.V., markets,
sells and  distributes  CEA-Scan  throughout  Western  Europe  and in  specified
Eastern  European  countries,  subject to receipt of regulatory  approval in the
specified  countries.  In April,  1996, the Company entered into a marketing and
distribution  agreement  with  Mallinckrodt  Medical,  Inc.,  pursuant  to which
Mallinckrodt Medical,  Inc., markets,  sells and distributes CEA-Scan for use in
colorectal  cancer  diagnostic  imaging in the U.S. on a consignment  basis (see
"Marketing and Sales" for the current status of these agreements).

         In August,  1995, the Company announced that its license agreement with
Pharmacia,  Inc.  (formerly Adria Laboratories  Division of Erbamont,  Inc., and
which  subsequently   became  Pharmacia  &  Upjohn)   ("Pharmacia"),   had  been
terminated.  In June,  1996, the Company filed a claim against  Pharmacia before
the American Arbitration Association claiming damages for breach of contract and
fiduciary  duty in an amount in excess of $60  million  plus  punitive  damages.
Final closing  arguments were made on September 17, 1997, and a decision  should
be forthcoming in the near future. The Company is unable at this time to predict
the outcome of these proceedings (see "Legal Proceedings").

         The  Company  was  incorporated  in  Delaware  in 1982.  The  Company's
principal  offices are located at 300 American Road,  Morris Plains,  New Jersey
07950. The Company's telephone number is (973) 605-8200.  The Company also has a
subsidiary,   Immunomedics  Europe,  with  offices  located  in  Hillegom,   The
Netherlands,  to assist the Company in managing sales and marketing  efforts and
coordinate clinical trials in Europe.

CLINICAL TRIAL PROGRAMS

         IN VIVO Imaging Products

         The Company's IN VIVO imaging  products  utilize  radioimmunodetection,
which involves injecting a patient with a radioisotope linked, or conjugated, to
an antibody.  An antibody is a protein that can recognize and selectively attach
itself to a specific  substance called an antigen.  Such antigens are present on
tumor cells,  white blood cells that accumulate at the sites of infections,  and
other  disease  entities.  By attaching a  radioisotope  to a  disease-targeting
antibody,  the  radioisotope  may be delivered to a disease site for imaging.  A
gamma camera (standard nuclear medicine equipment used for imaging) is then used
to display  radioisotope  concentrations,  revealing the presence,  location and
approximate size of the site of disease.

         The  Company's IN VIVO imaging  products  utilize only one of the upper
arms of the  antibody,  the FAB'  fragment.  The  Company  uses its  proprietary
chemistry to produce the FAB' fragment of a  mouse-derived  antibody  capable of
direct and  virtually  instant  attachment or  "labeling"  with  technetium-99m.
Technetium-99m  is the  radioisotope  most frequently  used in nuclear  medicine
because of its high quality imaging  capabilities,  short half-life,  widespread
availability  and low cost.  The use of a fragment of the antibody,  rather than
the whole,  minimizes  the human  body's  immune  response to the  injection  of
mouse-derived  antibodies.  This benefit is enhanced by the low FAB' dosage used
in  the  Company's   imaging   products.   An  additional   advantage  of  using
technetium-99m  and an  antibody  fragment  is that  imaging is  enhanced in the
liver, the first site of distant metastasis for many cancers.  Intact antibodies
and certain other  imaging  radioisotopes  accumulate in the liver,  potentially
interfering with adequate imaging of tumors in this organ.

         The Company's IN VIVO imaging products,  contained in single vials, can
be easily prepared by nuclear  medicine  technicians  without  assistance from a
radiochemist or nuclear pharmacist. Once the technetium-99m is added to the vial
in a saline solution,  the product is ready for injection in approximately  five
minutes.

         On June 28,  1996,  the FDA  licensed  CEA-Scan  for the  detection  of
colorectal cancer for use with other standard diagnostic modalities.  On October
4, 1996, this product also was approved by the European  Commission for the same
indication.  On September 16, 1997, the Company  received a notice of compliance
from the HPB  permitting  it to market  CEA-Scan  in Canada  for  recurrent  and
metastatic  colorectal  cancer. In addition,  Immunomedics has seven proposed IN
VIVO imaging  products or indications in various stages of clinical  testing and
regulatory  review by the FDA - four for cancer  imaging  (CEA-Scan for lung and
breast  cancer and  AFP-Scan  for liver and germ cell  cancer),  one for imaging
infectious  diseases  (LeukoScan),   one  for  non-Hodgkin's   lymphoma  imaging
(LymphoScan), and one for the specific imaging of Pneumocystis carinii pneumonia
("PCP")(PCP-Scan(TM)).


                                       3
<PAGE>

         The  antibody  in CEA-Scan  is  directed  at  carcinoembryonic  antigen
("CEA"),  which is abundant at the site of virtually all cancers of the colon or
rectum (both primary tumors and  metastases).  CEA is also  associated with many
other cancers, and the Company estimates that three quarters of all human cancer
patients  have  elevated  CEA levels at some of their  tumor  sites.  As part of
receiving FDA approval for CEA-Scan,  the Company has agreed to conduct Phase IV
clinical studies to evaluate the product following readministration. The Company
also is performing Phase III clinical trials,  using CEA-Scan,  for imaging lung
cancer.  In addition,  Phase II clinical  trials for breast cancer  imaging have
been completed, results of which are currently being discussed with FDA and CPMP
officials  to  determine  whether  such  data will  support  the  submission  of
applications   for  this   additional   indication   in  the  U.S.  and  Europe,
respectively.

         LeukoScan is a monoclonal  antibody  fragment which seeks out and binds
to granulocytes  (white blood cells) associated with a potentially wide range of
infectious  diseases.  On  February  14,  1997,  the Company  received  European
regulatory   approval  to  market  the  product  for  detecting  and  diagnosing
osteomyelitis  (bone  infection)  in  long  bones  and in  diabetic  foot  ulcer
patients.  On December 19, 1996,  the Company filed a BLA with the FDA,  seeking
approval to market  LeukoScan  in the U.S. for the same  indication  approved in
Europe,  plus  an  additional   indication  for  diagnosis  of  acute,  atypical
appendicitis.  The  Company  is also  discussing  with the  European  regulatory
authorities   expansion  of  the  LeukoScan   approval  to  include  the  latter
indication.

         Two  other  imaging  products  are  being  studied  pursuant  to  IND's
submitted to the FDA. The Company also has ongoing clinical trials in Europe for
these agents:

         -        LymphoScan,  employing  an antibody  capable of  targeting  an
                  antigen on  non-Hodgkin's  B-cell lymphoma (Phase III clinical
                  trials are underway).

         -        AFP-Scan,   employing   an  antibody   capable  of   targeting
                  alpha-fetoprotein,  a marker  on liver  cancer  and germ  cell
                  tumors of the ovaries and testes (Phase II clinical trials are
                  underway).

         PCP-Scan has been studied for the imaging and diagnosis of Pneumocystis
carinii  pneumonia  (PCP) in a pilot  clinical trial in  collaboration  with the
Center for Molecular Medicine and Immunology ("CMMI"),  a not-for-profit  cancer
research center (see  "Relationship  with the Center for Molecular  Medicine and
Immunology"). In these trials it has been shown that specific antibodies against
a  pathogenic  organism,  such as  Pneumocystis,  can target the  disease  site.
Further  studies to evaluate  this  potential  product are  beginning.  PCP is a
serious  opportunistic  infection of  immunosuppressed  patients,  such as organ
transplant  patients  and  certain  patients  with  cancer  or  Acquired  Immune
Deficiency Syndrome ("AIDS").

         IN VIVO Therapeutic Products

         The  Company  is  applying  its   expertise   in  antibody   selection,
modification and chemistry to cancer therapeutics,  using monoclonal  antibodies
labeled with therapeutic  radioisotopes or conjugated with drugs. The Company is
engaged in  developing  products  for  treating  cancer  which  primarily  use a
technique called  radioimmunotherapy.  The principal advantage of this technique
may be its ability to deliver radioactive therapeutic agents to tumor sites more
selectively, while minimizing debilitating side effects. The Company conducted a
multicenter  Phase I/II clinical trial with the murine form of its non-Hodgkin's
B-cell lymphoma proposed therapeutic product,  LymphoCide,  for over four years.
This product  consists of a monoclonal  antibody,  highly  specific in targeting
B-cell lymphomas,  labeled with the radioisotope iodine-131.  In this Phase I/II
clinical trial of LymphoCide,  several patients, all of whom were late-stage and
were  unresponsive  to other  therapies,  experienced  varying  degrees of tumor
regression.  Reversible  bone marrow  toxicity was also observed.  By conducting
this trial,  the Company  increased  its  knowledge  of antibody  targeting  and
dosage.  The Company is now advancing its humanized  antibody program into Phase
I/II clinical  trials and is  discontinuing  its trials with the murine antibody
form of LymphoCide.  The Company is currently conducting,  in collaboration with
CMMI and other  academic or research  centers,  research on murine and humanized
forms of targeting  antibodies,  alternative  radioisotopes  and new conjugation
methods (see "Research Programs").

RESEARCH PROGRAMS

         The  Company  incurred  approximately   $13,114,000,   $12,504,000  and
$12,492,000,  in total research and development  expense during its fiscal years
ended June 30, 1997, 1996 and 1995, respectively.

         Antibody Engineering

         A major obstacle in the field of monoclonal  antibody  therapy has been
the patient's immune response to mouse-derived  antibodies,  making repeated use
of such products  impracticable.  The Company is currently  researching  whether
this response may be avoided by clinically altering the dose, antibody form, and
schedule of administration.  However, this may be only a partial solution to the
problem  and,  consequently,  the Company is actively  investigating  methods to
engineer the mouse antibody molecule in such a way that it retains the desirable
targeting   features  to  cancer  cells,   and  also  minimizes  the  amount  of
mouse-derived  protein  present.  The Company has made  significant  progress in
humanizing  certain mouse antibodies (i.e.,  replacing  certain  components of a
mouse antibody with human  antibody  components),  and with respect  thereto the
Company  has  licensed  technology  from a  third  party.  Moreover,  using  the
techniques of molecular biology, the Company's scientists have re-engineered the
humanized   antibodies   with  improved   characteristics,   such  as  favorable
pharmacokinetic   properties  and  increased   radionuclide   and  drug  loading
capacities.


                                       5
<PAGE>

         During fiscal years 1997, 1996 and 1995, the Company,  in collaboration
with CMMI,  continued to demonstrate  successful  targeting in patients with the
Company's  humanized  monoclonal  antibodies  (hMN-14 and hLL2)  against the CEA
cancer marker and non-Hodgkin's  B-cell lymphoma,  respectively,  as compared to
the murine counterparts (MN-14 and LL2). The anticancer humanized antibodies are
about 95% human and have  shown very good  uptake in the  patients'  tumors.  In
August, 1995, data were presented from a pilot clinical trial which demonstrated
that  the  low  immunogenicity  and  high  cancer-binding  capability  of  these
antibodies allowed repeated administration to increase the amount of therapeutic
radiation  delivered  directly  to the  sites  of  disease.  As  many  as  three
injections  were given  without  evoking  an immune  response  to the  antibody.
Accordingly,  the Company has  proceeded  with clinical  testing at  therapeutic
doses.

         Alternative Radioisotopes

         The Company has used  iodine-131  to label its  anti-lymphoma  antibody
(LL2),  which  has  been  evaluated  in a  phase  I/II  clinical  trial  against
non-Hodgkin's  lymphoma.  This disease has previously been found to respond well
to  radioimmunotherapy  using iodine-131-  labeled,  murine-based  anti-lymphoma
antibodies by  investigators  at several  institutions.  However,  one potential
drawback of an  iodine-131-labeled  LL2  antibody is the finding  that LL2, as a
rapidly internalizing antibody, is readily metabolized with the iodine-131-bound
metabolite  and is quickly  excreted from the target cell.  This means that full
advantage  is  not  taken  of  the   eight-day   half-life  of  the   iodine-131
radionuclide,  in this one  particular  disease.  In contrast,  yttrium-90  from
administered  yttrium-90  labeled  LL2 has  been  shown  to be  retained  inside
lymphoma cells for long periods after antibody metabolism.  For this reason, and
also for reasons of greater efficacy against larger tumors and the potential for
out-patient use due to lack of any associated gamma-ray emissions, the Company's
scientists are developing  yttrium-90-LL2  as a  second-generation  product (see
"Government  Grants").  The Company anticipates  beginning a Phase I/II clinical
trial early in calendar year 1998, or earlier.

         New Conjugation Methods

         During fiscal year 1997,  the Company made  additional  progress in the
development of new methods for the construction of  immunoconjugates,  utilizing
the discovery of novel  carbohydrate  components  on the variable  region of the
lymphoma  targeting  antibody,  LL2,  which  facilitates  the  creation  of more
efficient  immunoconjugates,  and which appears to be  appropriate  for use with
antibody  fragments.  These carbohydrate  components are relatively distant from
the antigen-binding site,  representing novel conjugation sites, which would not
interfere  with  the  immunoreactivity  of the  antibody.  This  is  significant
because,  to date,  efforts  to  directly  link  antibodies  and drugs have been
limited  by a  resulting  loss of the  antibody's  ability to bind to the cancer
site.  This work  supports the  Company's  hypothesis  that,  by using  antibody
engineering


                                       6
<PAGE>


techniques,  this  carbohydrate  component can be "grafted" on the corresponding
regions  of  different  antibodies  and  used  as a  conjugation  site  for  the
attachment   of   drugs   or   radioisotopes   with  no   adverse   effects   on
immunoreactivity.  Furthermore,  the  Company's  scientists  have  been  able to
engineer  this  carbohydrate  addition site on antibody  fragments.  The Company
believes that this has the advantage of greater tumor penetration and less human
immune response,  potentially  leading to the creation of fragment-based  cancer
therapeutics  as a central  part of the  Company's  future  product  development
efforts. A patent was issued to the Company in August, 1995, relating to the use
of one of these sites for conjugation.  There can be no assurance, however, that
these  developments  will lead to  products  that are  successful  for  treating
cancers in patients.

         Other Antibody-Directed Therapy Approaches

         The Company is  continuing  work on selective  coupling of  therapeutic
site-specific   agents  onto  engineered   carbohydrate   residues  on  antibody
fragments.  The proprietary  antibody  constructs offer the advantage of loading
multiple  therapeutic  moieties onto antibody fragments at a particular site and
in a manner,  which is known not to interfere with antigen binding.  The Company
also is  continuing  to  investigate  "pre-targeting",  whereby an  antibody  is
administered first and then followed by a separate radionuclide  administration.
Secondary recognition groups are attached, one to the targeting antibody and the
other to the  radionuclide,  such  that the  radionuclide  is  localized  to the
antibody  pre-targeted  to the tumor  site.  Using such  methods in  preclinical
animal tumor models,  target-to-blood  uptake ratios of  radionuclide  have been
improved by orders of  magnitude  compared to the antibody  radiolabeled  in the
conventional manner. The advantage of markedly increased  target-to-blood ratios
is somewhat offset by the greater complexity involved in multiple administration
and timing of  reagents.  Accordingly,  there can be no assurance at the present
time that this "pre-targeting"  approach will offer a practical  alternative for
radioimmunotherapy.

         Peptides

         During  fiscal  year  1997,  the  Company   continued  to  improve  its
proprietary  methods for  technetium-99m  radiolabeling of peptides,  which were
successfully  developed in fiscal year 1996, up to  clinical-scale  levels using
single vial kits. These automated synthetic methods will be generally applicable
to the preparation of  radioconjugates  of other diverse  chelate-peptides,  and
will enable rapid evaluation of different peptide-receptor systems directly with
peptide analogs labeled with technetium-99m,  the optimum imaging  radionuclide.
This technology has been applied to the preparation of analogs of  somatostratin
and has demonstrated  reagent utility in preclinical IN VIVO models.  In related
work,   similar  novel  synthetic   methods  have  also  been  used  to  prepare
chelate-peptide  conjugates  which  can  be  radiolabeled  with  indium-111  and
yttrium-90.

         Intraoperative Cancer Detection

         The  Company  has  been  developing   intraoperative  cancer  detection
applications with CEA-Scan, utilizing hand-held, radiation-detecting probes. The
Company has learned that surgeons have  successfully  used CEA-Scan in this way,
within 48 hours of its injection and external imaging.  A U.S. patent was issued
in 1990 to the  Company  for  this  and  endoscopic  applications,  and  another
important  patent  will soon be  issued.  The  company  is  planning  additional
clinical  trials  in  support  of  gaining  regulatory  approval  for  this  new
intraoperative  use of CEA-Scan.  However,  there can be no assurance  that such
clinical trials or regulatory filings will be successful.

         Government Grants

         During  fiscal  year  1997,  the  Company  was  awarded a phase I Small
Business  Innovation  Research ("SBIR") grant from the National Cancer Institute
("NCI")  of the  National  Institutes  of  Health,  for  $100,000,  for  therapy
applications using the Company's antibodies. The grant covers the development of
radioiodinated  antibodies,  prepared  using novel  chemistries,  from which the
iodine-131 is retained for extended periods inside tumor cells (like yttrium-90)
for enhanced  radioimmunotherapy.  Also during fiscal year 1997, the Company was
awarded a SBIR  Phase I grant for  $100,000  supporting  the  development  of an
antibody-targeted   drug  for  the  treatment  of  PCP  (see  "IN  VIVO  Imaging
Products").

RELATIONSHIP WITH THE CENTER FOR MOLECULAR MEDICINE AND IMMUNOLOGY

         The Company's  product  development has involved,  to varying  degrees,
CMMI, a specialized cancer research center, for the performance of certain basic
research and patient  evaluations.  CMMI is a not-for-profit  corporation funded
primarily by grants from the NCI. CMMI was  previously  located  adjacent to the
Company's former Newark,  New Jersey  manufacturing  facility (Newark Facility),
but in November,  1996, moved to improved facilities in Belleville,  New Jersey.
Dr. David M.  Goldenberg,  Chairman of the Board and Chief Executive  Officer of
the Company,  is the  founder,  current  President  and a member of the Board of
Trustees of CMMI. Dr. Goldenberg  devotes more of his time working for CMMI than
for  the  Company.   Certain   consultants   to  the  Company  have   employment
relationships  with CMMI, and Drs. Carl Pinsky and Hans Hansen,  officers of the
Company,  are adjunct  members of CMMI.  Despite  these  relationships,  CMMI is
independent of the Company,  and CMMI's management and fiscal operations are the
responsibility  of CMMI's  Board of Trustees  (see  "Certain  Relationships  and
Related Transactions").

         CMMI  performs  pilot  and  pre-clinical  trials  in  product  areas of
importance to the Company. In addition,  CMMI and its clinical  subsidiary,  The
Garden State Cancer Center,  conduct basic research and patient evaluations in a
number of areas of potential  interest to the Company,  the results of which are
made available to the Company  pursuant to a collaborative  research and license
agreement.

         Effective July,  1995, the Company  amended its license  agreement with
CMMI to assist CMMI in complying with Internal  Revenue Service criteria for its
then recently  completed  tax-exempt  financing.  Under the terms of the amended
license  agreement,  the  Company has the right of first  negotiation  to obtain
exclusive,  worldwide  licenses from CMMI to  manufacture  and market  potential
products  and  technology   covered  by  the  license   agreement   under  terms
representing  fair market price,  to be negotiated in good-faith at the time the
license is obtained.  To date, no products  have been  licensed  from CMMI.  The
Company  retains  licensing  rights to  inventions  made  during the term of the
agreement  for a period of five years from the time of  disclosure.  The amended
license  agreement  terminates on December 31, 1999, with the Company having the
right to seek  good-faith  negotiation to extend the agreement for an additional
five-year period.


                                       8
<PAGE>

         The  potential  for  conflicts of interest  exists in the  relationship
between the Company and CMMI,  and the  provisions of the agreement  between the
Company and CMMI have been designed to prevent such  conflicts  from  occurring.
The  Company and CMMI have agreed  that  neither  will have any right,  title or
interest in or to the research grants, contracts or other agreements obtained by
the other. The decision as to whether a potential  product has reached the stage
of  development  such that it must be offered by CMMI to the  Company is made by
the Board of Trustees of CMMI, and Dr.  Goldenberg has agreed not to participate
in the determination of any such issue.  Similarly,  the decision by the Company
as to whether or not to exercise  its right of first  negotiation  or release of
any  potential  product  offered by CMMI is determined by a majority vote of the
Board of Directors (or a subcommittee  thereof),  and Dr.  Goldenberg has agreed
not to participate in the determination of any such issue.

         The Company has reimbursed CMMI for expenses  incurred on behalf of the
Company,  including  amounts  incurred  pursuant to research  contracts,  in the
amount of approximately $69,000, $64,000 and $57,000 during the years ended June
30, 1997, 1996 and 1995, respectively.  The Company also provides, at no cost to
CMMI, laboratory materials and supplies in connection with research conducted in
areas of potential interest to the Company.

         During  the  years  ending  June 30,  1997,  1996 and 1995 the Board of
Directors of the Company made grants to CMMI of $200,000, $200,000 and $300,000,
respectively,  to support  research and clinical  work being  performed at CMMI,
such  grants  to be  expended  in a manner  deemed  appropriate  by the Board of
Trustees of CMMI.  Pursuant to a collaborative  research and license  agreement,
dated as of January 21,  1997,  between  the  Company and CMMI,  the Company has
agreed to pay CMMI an annual license fee of $200,000.

BUSINESS RISKS

         The Company's  products are in various stages of development and face a
high degree of technological,  regulatory and competitive risk. In addition, the
Company's products must be approved for marketing by regulatory agencies such as
the FDA (with the exception of CEA-Scan and LeukoScan,  which have been licensed
as  discussed  above),  and no  assurance  can be  given  as to if or when  such
approvals could be  forthcoming.  Product  discovery and development  activities
require  substantial cash outlays.  At least until CEA-Scan and/or LeukoScan are
successfully  commercialized,  future  revenues  will be dependent in large part
upon the Company entering into new arrangements with collaborative  partners and
upon public and private financings.  In addition,  the Company has only recently
established  a sales and  marketing  organization,  including  the  addition  of
specialized  salesforces in the U.S. and Europe (see "Marketing and Sales").  No
assurance  can  be  given  that  the  Company's   manufacturing  costs  will  be
economically  viable,  or that the Company can  develop an  effective  sales and
marketing strategy to effectively promote any marketed product.

         The risks  discussed  herein reflect the Company's  immediate  stage of
development.  Inherent in this stage is a range of additional  risks,  including
the Company's  history of losses and the need for, and uncertainty of, obtaining
future financing. The Company also faces numerous risks stemming from the nature
of the  biopharmaceutical  industry,  including  the  risk  of  competition  and
competing patents, the risk of regulatory change, including potential changes in
health care coverage, and uncertainties  associated with obtaining and enforcing
patents and proprietary technology, among others.

MARKETING AND SALES

         IN VIVO Products

         The  Company's   marketing  strategy  initially  consisted  of  forming
corporate alliances with pharmaceutical  companies for the sale and distribution
of its proposed IN VIVO imaging and therapeutic products,  whereby the partner's
established  marketing,  sales and  distribution  networks  would  minimize  the
Company's need to expend funds to develop these areas of expertise. However, the
Company now believes that  development of its own salesforce,  complementary  to
those  of its  partners,  will  be  necessary  to  increase  the  likelihood  of
maximizing market penetration for its products.

         In March,  1995,  the Company  entered  into a license  agreement  with
Mallinckrodt Medical B.V., pursuant to which Mallinckrodt Medical B.V., markets,
sells and  distributes  CEA-Scan  throughout  Western  Europe  and in  specified
Eastern  European  countries,  subject to receipt of regulatory  approval in the
specified countries.  The Company manufactures  CEA-Scan, for which Mallinckrodt
Medical B.V.,  pays the Company a  pre-determined  percentage of the net selling
price.

         In April,  1996, the Company entered into a Marketing and  Distribution
Agreement  with  Mallinckrodt  Medical,  Inc.,  pursuant  to which  Mallinckrodt
Medical,  Inc.,  markets,  sells and distributes  CEA-Scan for use in colorectal
cancer diagnostic imaging in the U.S. on a consignment basis, and is required to
commit financial resources to this effort. The Company retains manufacturing and
co-promotional  rights, pays Mallinckrodt Medical, Inc., a pre-determined amount
or  percentage  of the net selling  price,  and is allowed to commit  additional
financial  resources to promotional  activities.  In connection  therewith,  the
Company has entered into an agreement with MMD Specialty Services,  Inc. ("MMD")
pursuant to which MMD will provide the Company,  during fiscal year 1998, with a
full-time  oncology  sales force for the  marketing  and sale of CEA-Scan in the
United States.

         The Company has not been satisfied with the performance of Mallinckrodt
Medical B.V., or Mallinckrodt Medical,  Inc.,  (collectively,  the "Mallinckrodt
Affiliates") under the respective agreements. This has raised a number of issues
which have been the subject of meeting and  correspondence  between the parties.
If these issues cannot be resolved,  the Company may have no alternative  but to
terminate the agreements with the  Mallinckrodt  Affiliates for what it believes
to be cause  under  those  respective  agreements.  Meanwhile,  the  Company  is
exploring  potential  relationships  with new  distributors  for CEA-Scan in the
United  States  and  Europe.  At the  same  time,  working  with  its  marketing
consultant, the Company has been building, directly and through MMD, an oncology
sales and marketing force in the United States. See "Legal Proceedings".


                                       10
<PAGE>

         The  Company  is  currently  negotiating  with  several  companies  for
marketing and distribution rights to CEA-Scan in Canada.

         In connection with the launch of LeukoScan in Europe, which occurred in
April, 1997, the Company has retained all marketing, selling and distribution of
the product and is in the process of adding  personnel to assist in this effort.
Accordingly,  the Company has moved its European  operations  to new  facilities
in Hillegom, The Netherlands.

         The Company's intent,  possibly in collaboration with another corporate
partner,  is to combine  LymphoScan with the Company's proposed lymphoma therapy
product,  LymphoCide,  as companion  detection/therapy  clinical applications to
focus on disease management for lymphoma patients.

MANUFACTURING

         To  date,  the  Company  has  manufactured  all  materials  used in its
clinical  trial programs and currently  manufactures  CEA-Scan and LeukoScan for
commercial use. The Company performs antibody processing and purification of its
clinical products at its Morris Plains, New Jersey, facility (see "Properties").
The Company has agreed to manufacture  and supply all of  Mallinckrodt  Medical,
Inc.'s and Mallinckrodt  Medical B.V.'s  requirements  for CEA-Scan,  subject to
certain   conditions  and  limitations,   and  will  receive  transfer  fees  in
consideration  therefore (see  "Marketing  and Sales").  The Company has entered
into a manufacturing  agreement with SP  Pharmaceuticals,  formerly the Oncology
Division of Pharmacia & Upjohn,  pursuant to which SP  Pharmaceuticals  performs
certain end-stage portions of the manufacturing process. Under the terms of such
agreement,  the Company pays  according to an  established  price  structure for
these  services.  The Company has  identified  and  qualified a second entity to
perform  similar  end-stage   manufacturing  and  is  presently  negotiating  an
agreement with such entity.



                                       11
<PAGE>


         In  February,   1997,  the  Company  closed  its  Newark,  New  Jersey,
manufacturing facility and moved these operations to the Company's Morris Plains
headquarters,  which also houses regulatory,  medical, research and development,
finance, marketing and executive offices (see "Properties"). The Company has now
scaled-up to  commercial  levels its  antibody  purification  and  fragmentation
manufacturing  processes.  The  new  manufacturing  facility  consists  of  four
independent  antibody-manufacturing suites, several support areas, and a quality
control  ("QC")  laboratory.  Start-up  validation  and  inspection  of the  new
facility has been completed,  encompassing the adoption of a new, more efficient
manufacturing process.  However, there can be no assurance at this time that the
regulatory authorities will approve this facility in a timely manner to meet the
manufacturing needs of the Company.

         The  Company's  proposed  monoclonal  antibody  products are  currently
derived from ascites fluid produced in mice, and the Company has entered into an
agreement  with a  third-party  supplier for the  production  of ascites  fluid.
Although  CEA-Scan  has been  approved  in the U.S.,  Canada,  and  Europe,  and
LeukoScan has been approved in Europe,  regulatory authorities,  particularly in
Europe,  have expressed  concerns about the use of ascites for the production of
monoclonal  antibodies.  The Company  believes that its current  quality control
procedures help ensure the purity of the ascites used in its products, but there
can be no  assurance  that the  regulatory  authorities  will  agree  that these
procedures will be adequate for future products. The Company's effort to convert
to cell culture  production for certain  monoclonal  antibodies is  progressing.
Products manufactured by cell culture processes will require regulatory approval
for  this   substantial   change  in  process,   and  will  require   additional
manufacturing equipment and resources for this effort.

PATENTS AND PROPRIETARY RIGHTS

         The Company  actively  pursues a policy of seeking  patent  protection,
both in the United  States  and  abroad,  for its  proprietary  technology.  The
Company has a diverse  patent  portfolio  for its IN VIVO  diagnostic  products,
currently  consisting of 35 issued United States  patents and 193 issued foreign
patents, with 29 United States patent applications pending, of which 8 have been
allowed,  and 120  foreign  patent  applications  pending,  of which 2 have been
allowed. Included in the foregoing are 8 United States patents and their foreign
counterparts,  to which the Company has rights pursuant to an exclusive  license
granted by Dr.  Goldenberg.  The Company also has certain rights with respect to
patents and patent  applications owned by CMMI, by virtue of a license agreement
between the Company and CMMI.

         The Company  owns or has licensed  patents  that  contain  broad claims
covering  significant  aspects of current  radioimmunodetection  technology  for
tumor imaging with radiolabeled antibodies and antibody fragments.  These United
States  issued  patents  expire  beginning in 1999,  subject to extension  under
certain circumstances.  The Company's patents also contain broad claims relating
to tumor therapy with  radiolabeled  antibodies  and antibody  fragments.  These
patents contain claims  covering the Company's  potential IN VIVO cancer imaging
and therapeutic products currently under development.



                                       12
<PAGE>

         In March,  1997,  the Company  was issued a U.S.  patent with claims to
methods of treating  infection  and  autoimmune  disease with a  combination  of
antibody-targeted  drugs and  cytokines to mitigate  side  effects.  At the same
time,  a Japanese  patent was issued to the  Company  covering a class of highly
specific antibodies to the tumor-associated  marker CEA, their use for detection
of the CEA-specific  antigen in body fluids and tissues, and for the imaging and
treatment of cancers expressing the CEA marker.

         In  May,  1997,  the  Company  was  issued  a  U.S.   patent   covering
antibody-targeted  imaging  and therapy  using  chimeric  antibodies,  which are
proteins  engineered to resemble human  antibodies  but having  binding  regions
derived from non-human mammals.

         In June, 1997, the Company was issued two U.S. patents,  the first with
claims to an agent for imaging a tumor or an  infection,  for which the agent is
efficiently  excreted.  With resulting inhibited kidney uptake,  target sites in
proximity to the kidneys can be detected  more easily.  The second patent claims
methods of diagnosis and therapy of  infections  using an agent that can bind to
more than one kind of white blood cell. The enhanced binding capability can help
to more efficiently target a diagnostic or therapeutic component of the agent to
the infection.

         In July,  1997,  the  Company  was issued a U.S.  patent  covering  new
methods and agents for the imaging and detection of cardiovascular lesions, such
as  atherosclerotic  plaques,  vascular clots (including thrombi and emboli) and
myocardial  infarcts.  This  patent's  claims  involve  the  use of an  antibody
conjugate  targeted to  monocytes  or to other  antigens  present at the disease
site, such as platelets or fibrin.

         Pursuant to a License Agreement between the Company and Dr. Goldenberg,
certain patent applications owned by Dr. Goldenberg were licensed to the Company
at the time of the  Company's  formation in exchange for a royalty in the amount
of 0.5% of the first  $20,000,000 of annual net sales of all products covered by
any of such patents and 0.25% of annual net sales of such  products in excess of
$20,000,000. Dr. Goldenberg's Amended and Restated Employment Agreement with the
Company  dated  November  1,  1993  (the  "Employment  Agreement")  extends  the
ownership  rights of the Company,  with an obligation  to diligently  pursue all
ideas,  discoveries,  developments and products,  into the entire medical field,
which, at any time during his past or continuing  employment by the Company (but
not when performing  services for CMMI), Dr. Goldenberg has made or conceived or
hereafter  makes or  conceives,  or the  making  or  conception  of which he has
materially  contributed  to or hereafter  contributes  to, all as defined in the
Employment Agreement (collectively "Goldenberg Discoveries").

         Further,  pursuant to the Employment  Agreement,  Dr.  Goldenberg  will
receive  incentive  compensation of 0.5% on the first $75,000,000 of all defined
Annual Net  Revenue of the  Company  and 0.25% on all such Annual Net Revenue in
excess  thereof  (collectively  "Revenue  Incentive  Compensation").  Annual Net
Revenue includes the proceeds of certain dispositions of assets or


                                       13
<PAGE>


interests  therein (other than defined  Undeveloped  Assets),  including defined
Royalties, certain equivalents thereof and, to the extent approved by the Board,
non-royalty  license  fees.  Revenue  Incentive  Compensation  will be paid with
respect to the period of Dr. Goldenberg's employment,  and two years thereafter,
unless  he  unilaterally  terminates  his  employment  without  cause  or  he is
terminated  by the  Company  for cause.  With  respect  to the  period  that Dr.
Goldenberg is entitled to receive  Revenue  Incentive  Compensation on any given
products, it will be in lieu of any other percentage compensation based on sales
or revenue due him with  respect to such  products  under this  Agreement or the
existing License Agreement between the Company and Dr. Goldenberg.  With respect
to any periods that Dr.  Goldenberg  is not  receiving  such  Revenue  Incentive
Compensation for any products covered by patented  Goldenberg  Discoveries or by
certain  defined  Prior  Inventions of Dr.  Goldenberg,  he will receive 0.5% on
cumulative annual net sales of, royalties on, certain equivalents thereof,  and,
to the extent approved by the Board, other consideration received by the Company
for such products,  up to a cumulative annual aggregate of $75,000,000 and 0.25%
on any  cumulative  Annual Net  Revenue in excess of  $75,000,000  (collectively
"Incentive  Payments").  A $100,000  annual minimum  payment will be paid in the
aggregate  against  all Revenue  Incentive  Compensation  and  Royalty  Payments
("Annual Minimum Payment") and the License Agreement (discussed above).

         Dr.  Goldenberg  also will receive a percent,  not less than 20%, to be
determined by the Board, of net consideration (including license fees) which the
Company receives for any disposition, by sale, license or otherwise (discussions
directed to which commence  during the term of his employment plus two years) of
any defined  Undeveloped Assets of the Company which are not budgeted as part of
the Company's strategic plan.

         Dr. Goldenberg will not be entitled to any incentive  compensation with
respect to any products,  technologies or businesses acquired from third parties
for a total consideration in excess of $5,000,000, unless the Company had made a
material  contribution  to  the  invention  or  development  of  such  products,
technologies or businesses prior to the time of acquisition.  Except as affected
by a  defined  Change  in  Control  or  otherwise  approved  by the  Board,  Dr.
Goldenberg  will also not be entitled to any Revenue  Incentive  Compensation or
Incentive  Payments  other than the Annual  Minimum  Payment with respect to any
time during the period of his employment (plus two years,  unless  employment is
terminated  by  mutual  agreement  or by Dr.  Goldenberg's  death  or  permanent
disability)  that he is not the  direct  or  beneficial  owner of  shares of the
Company's  voting stock with an aggregate  market value of at least twenty times
his defined annual cash compensation.

         Pursuant to a License  Agreement  dated July 7, 1983,  the Company must
pay to Dr. F.  James  Primus,  a  co-inventor  with Dr.  Goldenberg  of  certain
monoclonal  antibodies and  immunoassays  which are the subject matter of a U.S.
patent and foreign  counterparts  thereof that are owned jointly by Drs.  Primus
and  Goldenberg,  a royalty in the amount of 0.25% of the first  $20,000,000  of
annual net sales of certain  products  utilizing a CEA-specific  antibody (e.g.,
CEA-Scan),  and  0.125%  of  annual  net  sales of such  products  in  excess of
$20,000,000.


                                       14
<PAGE>

         The  Company  has  entered   into  patent   license   agreements   with
non-affiliated companies, pursuant to which the Company granted to the licensee,
for an initial  non-refundable fee plus royalties, a non-exclusive license under
the Company's  patents to manufacture and sell certain cancer imaging  products.
To date, no royalties have been received under these licenses. In addition,  the
Company has sought to enter into patent license  agreements  with companies that
may be  developing or marketing  products that could  infringe on one or more of
the patents which the Company owns or has licensed. In certain situations,  such
companies  have declined to enter into license  agreements  with the Company and
have raised  questions as to the scope and validity of certain of the  Company's
patents. Discussions are continuing with these companies and the Company intends
to vigorously  protect and enforce its patent  rights.  Although there can be no
assurances as to the outcome of any patent  disputes,  the Company believes that
its patents are valid and will be upheld if challenged.

         In November,  1996,  the Company  filed an  infringement  action in The
Netherlands against Hoffmann-La Roche for infringement of the Company's European
patent covering  specific anti-CEA  antibodies,  which Roche is using in its CEA
immunoassay.  The patent also covers the antibody, which the Company uses in its
CEA-Scan imaging product. The Company is seeking an injunction  prohibiting sale
of Roche's assay in The  Netherlands and other European Union countries in which
the Company's European patent has been issued. Roche has denied infringement and
has filed nullity  proceedings  in The  Netherlands  and in Germany,  seeking to
invalidate the Company's  patents in those countries.  The Company has filed its
Statement of Defense in the Dutch nullity action and expects to file shortly its
German  defense.  Trial on the  infringement  action  commenced  in The Hague on
August 8, 1997.  There can be no assurance  that the Company will prevail in the
infringement suit or that its patents will survive the nullity actions, although
the Company believes that Roche's  infringement  defense and nullity attacks are
unlikely to succeed.

         The Company also relies in part on trade secrets,  unpatented  know-how
and continuing technological  advancements to maintain its competitive position.
It is the practice of the Company to enter into confidentiality  agreements with
employees,  consultants  and  corporate  sponsors.  There  can be no  assurance,
however, that these measures will prevent the unauthorized  disclosure or use of
the Company's trade secrets and know-how.

         The mark  "IMMUNOMEDICS"  is  registered  in the  United  States and 20
foreign  countries,  and the  Company's  logo also is  registered  in the United
States and in several foreign  countries.  The mark "IMMUSTRIP" is registered in
the United  States and Canada.  The mark  "CEA-SCAN" is registered in the United
States  and 6 foreign  countries,  applications  are  pending  in three  foreign
countries and an application for a European Community Trademark is pending.  The
mark  "LEUKOSCAN"  is registered in the United States and 11 foreign  countries,
applications  are  pending  in 3 foreign  countries,  and an  application  for a
European   Community   Trademark  is  pending.   An  application  for  the  mark
"LYMPHOSCAN"  is pending  in the  United  States,  the mark is  registered  in 7
foreign  countries,  applications  are  pending in 2 foreign  countries,  and an
application  for a European  Community  Trademark is pending.  In addition,  the
Company has  applied for  registration  in the United  States for several  other
trademarks  for  use  on  products  now  in  development  or  testing,  and  for
corresponding  foreign and/or European Community Trademarks for certain of those
marks.

GOVERNMENT REGULATION

         The manufacture and marketing of pharmaceutical or biological  products
requires  approval of the FDA and comparable  agencies in foreign countries and,
to a lesser extent,  state  regulatory  authorities.  In the United States,  the
regulatory  approval process for antibody-based  products,  which are considered
"biologics" under FDA regulations, is similar to that for any new drug for human
use. The FDA has  established  mandatory  procedures  and safety  standards that
apply to the clinical  testing,  manufacturing  and marketing of  pharmaceutical
products.  Noncompliance  with  applicable  requirements  can  result  in fines,
recalls or seizure of  products,  total or  partial  suspension  of  production,
refusal  of the FDA to  approve  product  license  applications  or to allow the
Company to enter into supply contracts,  and criminal prosecution.  The FDA also
has  the  authority  to  revoke   previously   granted   product   licenses  and
establishment licenses.

         Generally,  there is a substantial period of time between technological
conception of a proposed  product and its  availability for commercial sale. The
period  between  technological  conception  and  filing of a  Biologics  License
Application with the FDA is usually five to ten years for IN VIVO products and a
minimum  of two to three  years for IN VITRO  diagnostic  products.  The  period
between the date of  submission to the FDA and the date of approval has averaged
two to four years for IN VIVO products,  although the approval  process may take
longer, as was the case with CEA-Scan.

         The amount of time taken for this  approval  process is a function of a
number of  variables,  including  the  quality  of the  submission  and  studies
presented,  the potential  contribution that the compound will make in improving
the  diagnosis  and/or  treatment of the disease in question and the workload at
the FDA.  There  can be no  assurance  that any new  product  will  successfully
proceed  through  this  approval  process  or that it  will be  approved  in any
specific  period of time.  Depending upon marketing and  distribution  plans and
arrangements for a particular  product,  the Company may require additional time
before a proposed IN VIVO product is available for commercial sale.

         The steps  required  before  biological  products  can be produced  and
marketed usually include  preclinical  non-human  studies,  the filing of an IND
application,  human  clinical  trials and the filing and  approval  of a BLA. In
addition to obtaining FDA approval for each  product,  the FDA must also approve
any production facilities for the product.

         Pre-clinical  studies are  conducted  in the  laboratory  and in animal
model systems to gain preliminary information on the drug's effectiveness and to
identify  major safety  problems.  The results of these studies are submitted to
the FDA as part of the IND  application  before approval can be obtained for the
commencement of testing in humans.  The human clinical  testing program required
for a new  biologic or  pharmaceutical  product  involves  several  phases.  The
initial clinical evaluation,  Phase I, consists of administering the product and
testing for safe and  tolerable  dosages while noting the  effectiveness  of the
product at the various dose levels. Typically, for cancer agents, testing is


                                       16
<PAGE>

done with a small  group of  patients  with  widespread  cancers  that have been
unresponsive  to other forms of  therapy.  Phase II involves a study to evaluate
the  effectiveness  of the product  for a  particular  indication  and to refine
optimal dosage and schedule of administration and identify possible side effects
and  risks in a  larger  patient  group.  When a  product  is  determined  to be
effective in Phase II trials, it is then evaluated in Phase III clinical trials.
Phase III trials consist of additional testing for effectiveness and safety with
a further expanded patient group,  usually at multiple test sites. A therapeutic
cancer  product  must be  compared to standard  treatments,  if such  treatments
exist, to determine its relative effectiveness in randomized trials.

         Human  clinical  trials of IN VIVO  monoclonal  antibody  products  may
combine Phase I and Phase II trials. In selected cases, a more traditional Phase
II study may be performed to examine the  effectiveness  of a single  product in
one or a limited  number of  configurations  or dose schedules in a single tumor
type.

         When Phase III studies are  complete,  the results of the  pre-clinical
and clinical studies, along with manufacturing information, are submitted to the
FDA in the  form  of a BLA.  The  BLA  involves  considerable  data  collection,
verification  and  analysis,  as well as the  preparation  of  summaries  of the
production and testing processes,  pre-clinical studies and clinical trials. The
BLA is submitted to the FDA for product marketing approval. The FDA must approve
the BLA and manufacturing facilities before the product may be marketed. The FDA
may also require post-marketing  testing,  including extensive Phase IV studies,
and  surveillance to monitor the effects of the product in general use.  Product
approvals  may be  withdrawn  if  compliance  with  regulatory  standards is not
maintained or if problems occur following initial  marketing.  In addition,  the
FDA may in some  circumstances  impose  restrictions on the use of the drug that
may limit its market  potential,  and also make it  difficult  and  expensive to
administer.

         The  Company  seeks to have its  proposed  products,  when  applicable,
designated as "Orphan  Drugs" under the Orphan Drug Act of 1983. The Orphan Drug
Act  generally  provides  incentives  to  manufacturers  to  develop  and market
products to treat relatively rare diseases,  i.e., diseases affecting fewer than
200,000  persons in the United  States.  The  Company has  received  Orphan Drug
designation  for,  among  others,  AFP-Scan,   LymphoScan  and  LymphoCide,  the
Company's liver and germ cell imaging, lymphoma imaging and lymphoma therapeutic
products,  respectively, and for CEA-Scan for the diagnosis of medullary thyroid
cancer. A drug that receives Orphan Drug designation and is the first product to
receive FDA marketing approval for its product claim is entitled to a seven-year
exclusive  marketing period in the United States for that claim for the product.
However,  a drug that is considered by the FDA to be different from a particular
Orphan Drug is not barred from sale in the United States during this  seven-year
exclusive marketing period.

         Manufacture of a biological  product must be in a facility  approved by
the FDA for such product.  The  manufacture,  holding and  distribution  of both
biological and nonbiological drugs must be in compliance with Good Manufacturing
Practices ("GMP"). Manufacturers must continue to


                                       17
<PAGE>

expend time,  money and effort in the area of production and quality  control to
ensure  full  technical  compliance  with  those  requirements.   The  labeling,
advertising  and promotion of drug or  biological  product must be in compliance
with FDA regulatory requirements. Failure to comply with applicable requirements
relating to manufacture,  distribution or promotion can lead to FDA demands that
production and shipment cease, and, in some cases, that products be recalled, or
to  enforcement  actions  that can include  seizures,  injunctions  and criminal
prosecution.  Such  failures,  or new  information  reflecting on the safety and
effectiveness  of the drug that comes to light after approval,  can also lead to
FDA withdrawal of approval to market the product.

         The drug  approval  process is similar in other  countries  and is also
regulated by specific agencies in each geographic area. Approval by the FDA does
not ensure approval in other countries.  Generally,  however,  products that are
approved by the FDA in the U.S. will ultimately gain marketing approval in other
countries, but may require considerable additional time to do so.

         The Company's  ability to commercialize  its products  successfully may
also  depend in part on the extent to which  reimbursement  for the cost of such
products  and  related  treatment  will  be  available  from  government  health
administration  authorities,  private health  insurers and other  organizations.
Such  third-party  payers  are  increasingly  challenging  the price of  medical
products  and  services.  Several  proposals  have  been made that may lead to a
government-directed national health care system. Adoption of such a system could
further limit reimbursement for medical products,  and there can be no assurance
that  adequate  third-party  coverage will be available to enable the Company to
maintain  price  levels  sufficient  to  realize an  appropriate  return on this
investment in product development.  In addition,  there can be no assurance that
the U.S.  government  will not  implement a system of price  controls.  Any such
system might adversely  affect the ability of the Company to market its products
profitably.

         The Company's present and future business is also subject to regulation
under state and Federal law regarding work place safety,  laboratory  practices,
the use and handling of  radioisotopes,  environmental  protection and hazardous
substance  control and to other present and possible  future local,  federal and
foreign regulations. The Company believes its operations comply, in all material
respects, with applicable environmental laws and regulations, and the Company is
continuing  its  efforts  to  ensure  its full  compliance  with  such  laws and
regulations.

COMPETITION

         The biotechnology  industry is highly competitive,  particularly in the
area of cancer  diagnostic,  imaging and  therapeutic  products.  The Company is
likely  to  encounter  significant  competition  with  respect  to its  proposed
products currently under development. A number of companies which are engaged in
the biotechnology  field, and in particular the development of cancer diagnostic
and  therapeutic  products,  have financial,  technical and marketing  resources
significantly greater than those of the Company. Some companies with established
positions in the pharmaceutical industry may be



                                       18
<PAGE>

better equipped than the Company to develop, refine and market products based on
technologies  applied to the diagnosis  and treatment of cancers and  infectious
diseases.  The Company's  ability to compete in the future will depend, in part,
on its ability to foster an environment in which  multi-disciplinary  teams work
together to develop low-cost,  well-defined  processes and bring cost-beneficial
products  successfully  through  clinical  testing and  regulatory  approval.  A
significant  amount of research and  antibody-based  technology are also carried
out at  universities  and other  non-profit  research  organizations,  which are
becoming  increasingly  aware of the commercial  value of their findings and are
becoming more active in seeking patent and other proprietary  rights, as well as
licensing revenues.

         The Company is pursuing an area of product  development  in which there
is the  potential  for extensive  technological  innovation in relatively  short
periods of time. The Company's  competitors  may succeed in developing  products
that are safer or more effective than those of the Company's potential products.
Rapid technological change or developments by others may result in the Company's
present products and potential products becoming obsolete or non-competitive.

         The Company believes that the technological  attributes of its proposed
diagnostic imaging products, including the ease of use (e.g., single vial, rapid
imaging),  employment of technetium-99m (the most widely available radioisotope)
and its use of an  antibody  fragment  (better  liver  imaging,  decreased  HAMA
response) will enable the Company to compete effectively in the marketplace.

         EMPLOYEES

         As of  September  26,  1997,  the  Company  employed  91  persons  on a
full-time basis, 23 of whom are in research and development  departments,  22 of
whom are engaged in clinical  research and  regulatory  affairs,  21 of whom are
engaged in operations and manufacturing,  and 25 of whom are engaged in finance,
administration and marketing.  Of these employees,  20 hold M.D., Ph.D. or other
advanced degrees. In addition,  through MMD, there are 14 sales  representatives
working in  marketing.  The  Company  believes  that it has been  successful  in
attracting skilled and experienced  scientific personnel;  however,  competition
for such personnel is intensifying. The Company's employees are not covered by a
collective bargaining agreement,  and the Company believes that its relationship
with its employees is excellent.

ITEM 2--PROPERTIES

         The  Company's  headquarters  is located at 300 American  Road,  Morris
Plains,  New Jersey,  where it leases  approximately  60,000  square  feet.  The
Company has a seven-year  lease expiring in May, 1999,  plus two renewal periods
for a total of 15 years,  at a base annual rental of $471,000  through May, 1998
and $448,000 through May, 1999. The lease provides for an option to purchase the
facility, subject to certain terms and conditions as specified in the lease. The
Company's regulatory,  medical, research and development laboratories,  finance,
marketing  and  executive  offices  are  currently  located  in  this  facility,
occupying  approximately  40,000 square feet. The Company has also completed the
construction and equipping of a 7,500 square-foot commercial-scale manufacturing
facility at its Morris Plains  headquarters,  which consists of four independent
antibody  manufacturing suites,  several support areas, and a QC laboratory (see
"Manufacturing").  In addition, the Company's European subsidiary,  Immunomedics
Europe, leases executive office space in Hillegom, The Netherlands.

ITEM 3--LEGAL PROCEEDINGS

         Pursuant  to its 1991  agreement  with Adria  Laboratories  Division of
Erbamont, Inc., which later became Pharmacia,  Inc. and subsequently Pharmacia &
Upjohn  ("Pharmacia"),  the Company granted to Pharmacia an exclusive license to
market and sell CEA-Scan, AFP-Scan and LymphoScan products for certain specified
indications  in the United  States and Canada.  In June,  1994,  the Company and
Pharmacia,  in the context of discussions  directed towards  restructuring their
relationship,  agreed to release Pharmacia from certain obligations, whereby the
Company  regained  the  marketing  and  selling  rights  and  assumed  financial
responsibility  for all future  clinical,  marketing and selling  activities for
LymphoScan  and  AFP-Scan.  On August 2, 1995,  the Company  announced  that its
agreement with Pharmacia was  terminated,  and that the Company had regained the
North  American  marketing  and  selling  rights for  CEA-Scan  from  Pharmacia.
Subsequent to  termination  of the  Agreement,  the Company and  Pharmacia  were
unable to agree on the amount of a final  payment by Pharmacia to the Company to
satisfy Pharmacia's  remaining  obligations.  In June, 1996, the Company filed a
claim against  Pharmacia before the American  Arbitration  Association  claiming
damages for breach of contract and  fiduciary  duty in the amount of $60 million
plus punitive damages.  Arbitration proceedings commenced soon thereafter. Final
closing  arguments  were made on September  17, 1997,  and a decision  should be
forthcoming in the near future. The Company and its attorneys are unable at this
time to predict the outcome of the case.

         As  described  in  "Business-Marketing   and  Sales",  the  Company  is
attempting  to  resolve a number of  outstanding  issues  with the  Mallinckrodt
Affiliates under the respective agreements with those entities. In the course of
those  attempts,  the Company  understood that the  Mallinckrodt  Affiliates had
agreed in principle to the Company's request to the voluntary termination of the
respective  agreements  and  the  return  to the  Company  of all  their  rights
thereunder with respect to CEA-Scan, with full cooperation during the transition
period. However, the Mallinckrodt Affiliates are denying that there was any such
agreement  in  principle,  asserting  that  they  are  awaiting  a  proposal  of
definitive  terms and  conditions,  including  an exchange  of general  releases
covering such  termination,  and further alleging breaches by the Company of the
respective   agreements  and  tortuous   interference   with  the   Mallinckrodt
Affiliates' alleged contractual relationships. The Company does not believe that
is has breached  either of the agreements or that it has  tortuously  interfered
with any alleged contractual  relationships.  Moreover, the Company is unwilling
to give the releases demanded by the Mallinckrodt  Affiliates without having the
opportunity to evaluate the full extent of damages the Company may have suffered
as a result of what it believes to be the failure of the Mallinckrodt Affiliates
to perform their  obligations  under the  agreements and has reserved all of its
rights and remedies in connection therewith including the right to terminate the
agreements  and to  damages,  if the  outstanding  issues  cannot  otherwise  be
resolved.

         The Company is involved in various other claims and litigation  arising
in the normal course of business.  Management  believes that the outcome of such
claims and litigation  will not have a material  adverse effect on the Company's
financial position and results of operations.

ITEM 4--SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matter was  submitted  to a vote of  securities  holders  during the
fourth quarter of fiscal year 1997.

ITEM 7--MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

OVERVIEW

         Statements  made  in  this  Form  10-K,  other  than  those  concerning
historical  information,  should be  considered  forward-looking  and subject to
various risks and uncertainties.  Such forward-looking statements are made based
on management's belief as well as assumptions made by, and information currently
available to, management pursuant to the `safe harbor' provisions of the Private
Securities  Litigation  Reform Act of 1995.  The  Company's  actual  results may
differ  materially  from  the  results  anticipated  in  these   forward-looking
statements as a result of a variety of factors,  including  those  identified in
"Business"  and elsewhere in this Annual Report on Form 10-K for the fiscal year
ended June 30, 1997.

         Since its  inception,  the Company has been  engaged  primarily  in the
research  and  development  and,  more  recently,   the   commercialization   of
proprietary  products  relating to the  detection,  diagnosis  and  treatment of
cancer and infectious diseases.  On June 28, 1996, the FDA licensed CEA-Scan for
the detection of recurrent and/or  metastatic  colorectal  cancer. On October 4,
1996, the European  Commission  granted  marketing  authorization for use of the
product in the 15 countries comprising the European Union. On February 19, 1997,
the  Company  received  European  Commission  approval  for  LeukoScan  for  the
diagnosis of  osteomyelitis  in long bones and in patients  with  diabetic  foot
ulcers. The product is currently under review by the FDA for the same indication
approved in Europe,  with the  additional  indication  for  diagnosis  of acute,
atypical  appendicitis.  On September 16, 1997, the Company received a notice of
compliance from the HPB permitting it to market CEA-Scan in Canada for recurrent
and metastatic colorectal cancer.

         The  Company is also  engaged  in  developing  other  biopharmaceutical
products,  which are in various stages of development and clinical testing.  The
Company has not achieved profitable operations and does not anticipate achieving
profitable  operations  during  fiscal year 1998.  The Company will  continue to
experience  operating  losses  until  such time,  if at all,  that it is able to
generate  sufficient revenues from sales of CEA-Scan,  LeukoScan,  and its other
proposed IN VIVO products.  Further, the Company's working capital will continue
to  decrease  until such time,  if at all,  that the Company is able to generate
positive  cash flow from  operations  or until  such time,  if at all,  that the
Company  receives an additional  infusion of cash from the sale of the Company's
securities,  from other  financings or from  corporate  alliances to finance the
Company's operating expenses and capital expenditures.

RESULTS OF OPERATIONS
FISCAL YEAR 1997 COMPARED TO FISCAL YEAR 1996

         Revenues for fiscal year 1997 were $3,841,000 as compared to $1,700,000
in fiscal year 1996,  representing  an increase of $2,141,000.  The increase was
principally  due to product  sales and an increase in research  and  development
revenues, partially offset by lower interest income. Product

                                       25
<PAGE>

sales and royalty  revenue for fiscal  year 1997 was  $1,975,000  as compared to
$186,000 in fiscal year 1996,  representing an increase of $1,789,000,  of which
$1,332,000 is attributable to product sales. In addition, the Company received a
license  fee of $500,000  from a corporate  partner.  Research  and  development
revenues  for fiscal  year 1997 were  $620,000 as compared to $150,000 in fiscal
year  1996,  representing  an  increase  of  $470,000  which is mainly due to an
increase in  government  grant  income.  Interest  income in fiscal year 1997 as
compared to fiscal year 1996  decreased  by  $236,000,  primarily as a result of
reduced  levels of cash  available for  investment  (see  "Liquidity and Capital
Resources").

         Total  operating  expenses  for fiscal  year 1997 were  $17,776,000  as
compared  to  $15,000,000  in fiscal  year 1996,  representing  an  increase  of
$2,776,000.  Research and development costs increased by $610,000 as compared to
fiscal year 1996 due to ongoing  validation of the  Company's new  manufacturing
facility and expenses  related to the filing of the  application  to the FDA for
approval of LeukoScan.  General and administrative costs increased by $2,179,000
as compared to fiscal year 1996.  This  increase  was  principally  due to legal
expenses of $944,000  incurred in connection  with a claim  against  Pharmacia &
Upjohn,  Inc. filed in June, 1996,  marketing  expenses for CEA-Scan of $674,000
and operating expenses for Immunomedics,  B.V. of $488,000,  which expenses were
not significant in the prior year.

         Net loss for fiscal year 1997 was  $13,947,000,  or $0.39 per share, as
compared to a net loss of $13,299,000,  or $0.40 per share, in fiscal year 1996.
The greater net loss resulted principally from higher general and administrative
expense  partially offset by product sales and increased  royalty  revenues,  as
explained above. The net loss per share for fiscal year 1997 was impacted by the
higher  weighted  average number of shares  outstanding  during such period,  as
compared to fiscal year 1996, due to the  conversion of the Company's  preferred
stock (see "Liquidity and Capital Resources").

FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995

         Revenues for fiscal year 1996 were $1,700,000 as compared to $3,189,000
in fiscal year 1995,  representing  a decrease of  $1,489,000.  The decrease was
principally due to a decrease in research and development revenue resulting from
the termination,  in August, 1995, of the Development and License Agreement with
Pharmacia.   Accordingly,   research  and  development   revenues  decreased  by
$1,728,500 to $150,000 in fiscal year 1996. In fiscal year 1995,  these revenues
totaled  $1,878,500,  of which  $1,665,000 was received from  Pharmacia.  Partly
offsetting  the  decline in  research  and  development  revenue  was  increased
interest  income of  $254,000  in fiscal  year 1996,  as compared to fiscal year
1995,  primarily as a result of higher levels of cash  available for  investment
resulting  from  completion of two financing  transactions  (see  "Liquidity and
Capital Resources").


                                       26
<PAGE>


         Total  operating  expenses  for fiscal  year 1996 were  $15,000,000  as
compared  to  $14,593,000  in fiscal  year 1995,  representing  an  increase  of
$407,000.  The increase was due to higher  general and  administrative  expense,
largely  due to  increases  in  consulting,  recruiting  and  employee  benefits
expenses of $178,000, $102,000 and $96,000,  respectively. The higher consulting
expenses were primarily due to a strategic  planning study  undertaken in fiscal
year 1996. The higher employee benefits expenses reflected higher payroll taxes,
due in part to the exercise of stock options by employees,  and higher  expenses
for executive life insurance for an executive  officer of the Company.  Research
and development costs in fiscal year 1996 were essentially unchanged from fiscal
year 1995.

         Net loss for fiscal year 1996 was  $13,299,000,  or $0.40 per share, as
compared to a net loss of $11,404,000,  or $0.38 per share, in fiscal year 1995.
The greater net loss resulted  principally  from lower research and  development
revenue and increased general and  administrative  expense,  as explained above.
The net loss per share for fiscal year 1996 was impacted by the higher  weighted
average  number of shares  outstanding  during such period as compared to fiscal
year 1995, which increase was principally due to the conversion of the Company's
preferred stock (see Liquidity and Capital Resources").

LIQUIDITY AND CAPITAL RESOURCES

         At June 30,  1997,  the  Company had  working  capital of  $11,753,000,
representing a decrease of $13,290,000  from June 30, 1996, and had no long-term
debt other than certain lease  obligations (see Note 11 of Notes to Consolidated
Financial Statements). The decrease in working capital resulted principally from
the funding of operating expenses and capital expenditures.

         On June 27, 1996, the Company completed an equity financing pursuant to
Regulation S under the  Securities  Act of 1933  ("Regulation  S"),  pursuant to
which  several  foreign  investors  purchased  200,000  shares  of 5%  Series  D
Convertible  Preferred  Stock (the "Series D Preferred")  for  $10,000,000.  The
terms of the transaction allowed the investors, at their discretion,  to convert
the Series D  Preferred  into  shares of the  Company's  common  stock  during a
twenty-four month period beginning in June, 1996, at a price equal to 89% of the
average market price per share over a 20-day trading period surrounding the date
of  conversion.  Dividends  on the Series D  Preferred  were  payable  annually,
commencing June 30, 1997, on all shares of Series D Preferred that have not been
converted into common stock as of the dividend payment date. (In August, 1997, a
dividend  payment of $12,498 was made.) As of June 30, 1997,  195,001  shares of
Series D Preferred had been  converted  into  1,733,439  shares of the Company's
common stock. In August,  1997, the remaining 4,999 shares of Series D Preferred
were converted into 62,332 shares of the Company's common stock.

         In addition,  during fiscal year 1997,  the remaining  28,415 shares of
the Company's Series C Preferred Stock (the "Series C Preferred") were converted
into 182,646  shares of the Company's  common  stock.  The Company had issued an
aggregate  of  200,000  shares of the  Series C  Preferred  in  fiscal  1996 for
$10,000,000.


                                       27
<PAGE>

         On August 2, 1995,  the  Company  announced  that its  Development  and
License  Agreement  with  Pharmacia  was  terminated  and that the  Company  had
regained the North  American  marketing  and selling  rights for  CEA-Scan  from
Pharmacia (see "Legal Proceedings").

         In February,  1994, the Company entered into a master lease  agreement,
which  was  subsequently  amended,  pursuant  to which  the  Company  may  lease
equipment  for  research,  development  and  manufacturing  purposes  having  an
aggregate  acquisition cost of up to $2,200,000.  The basic lease payments under
the master  lease  agreement  are  determined  based on current  market rates of
interest at the inception of each equipment  schedule  take-down and are payable
in monthly installments over a four-year period. The lease agreement contains an
early purchase option, at an amount that is deemed to be fair value, exercisable
no later  than  ninety  days  before the  thirty-sixth  installment  is due.  On
November  1, 1996,  December 9, 1996,  and April 1, 1997 the  Company  exercised
early purchase  options on equipment leased on February 14, 1994, April 1, 1994,
and June 1, 1994, respectively.

         Under the lease agreement,  continued compliance with certain financial
ratios is required and, in the event of default, the Company will be required to
provide  an  irrevocable  letter  of  credit  which  is  generally  equal to the
outstanding balance of lease payments due at the time of default. As of June 30,
1997, the Company has leased equipment with a cost basis aggregating  $1,247,000
under the master lease agreement and recorded lease expense for fiscal year 1997
of $497,000.

         The  Company's  liquid asset  position,  as measured by its cash,  cash
equivalents  and  marketable  securities,  was  $15,024,000  at June  30,  1997,
representing  a decrease of  $13,667,000  from June 30, 1996. It is  anticipated
that working capital and cash, cash equivalents,  and marketable securities will
decrease during fiscal year 1998 as a result of planned  operating  expenses and
capital expenditures, offset in part by projected revenues from product sales in
the U.S.  and Europe.  However,  there can be no  assurance  as to the amount of
revenues,  if any, these products will provide. At present, the Company believes
that its financial  resources will be sufficient to fund operating  expenses and
capital  expenditures through fiscal year 1998 based on reduced spending levels,
if necessary.  The Company  intends to supplement  its financial  resources from
time to time, as market conditions permit,  through additional  financing,  bank
loans and collaborative marketing and distribution agreements.  In addition, the
Company  continues to evaluate various programs to raise additional  capital and
to seek additional revenues from the licensing of its proprietary technology. At
the  present  time,  the  Company is unable to  determine  whether  any of these
activities  will be successful  and, in such cases,  the terms and timing of any
definitive  agreements or financing.  There can be no assurance that the Company
will be able to obtain additional funds in the future.

RECENTLY ISSUED ACCOUNTING STANDARDS

         In February  1997,  the  financial  Accounting  Standards  Board issued
Statement of Financial  Accounting  Standards No. 128 (SFAS 128),  "Earnings Per
Share". SFAS 128 establishes standards for computing and presenting earnings per
share. In accordance with the effective date of SFAS 128, the Company will adopt
SFAS 128 as of December  31,  1997.  This  statement  is not  expected to have a
material impact on the Company's financial statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       BUSINESS OVERVIEW

         Immunomedics,   Inc.  (the   "Company")  is  engaged  in   researching,
developing, manufacturing and marketing biopharmaceutical products, particularly
antibody-based diagnostics and therapeutics for cancer and infectious diseases.

         The Company's operations encompass all the risks inherent in developing
and  expanding a new business  enterprise,  including:  (1) a limited  operating
history and uncertainty regarding the timing and amount of future revenues to be
derived from the Company's  technology;  (2) obtaining future capital as needed;
(3) attracting and retaining key personnel;  and (4) a business environment with
heightened  competition,   rapid  technological  change  and  strict  government
regulation.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

         The  consolidated   financial   statements   include  the  accounts  of
Immunomedics, Inc. and its wholly-owned subsidiary. All significant intercompany
balances and transactions have been eliminated in consolidation.

CASH EQUIVALENTS AND MARKETABLE SECURITIES

         The Company considers all highly liquid  investments with maturities of
three months or less, at the time of purchase, to be cash equivalents.

         The Company's  investments  in marketable  securities are available for
sale to  fund  its  operations.  The  Company,  subject  to  changes  in  market
conditions,  does not intend to hold all marketable securities to their maturity
dates and,  accordingly,  the portfolio has been  classified as a current asset.
The portfolio primarily consists of U.S. government securities, corporate bonds,
and equity securities.

CONCENTRATION OF CREDIT RISK

         The Company  invests its cash in U.S.  government  securities  and debt
instruments  of  financial  institutions  and  corporations  with strong  credit
ratings. The Company has established  guidelines relative to diversification and
maturities  that  are  designed  to help  ensure  safety  and  liquidity.  These
guidelines are  periodically  reviewed to take advantage of trends in yields and
interest rates.

overhead.  Inventory at June 30, 1997 and 1996  consists of the cost of vials of
CEA-Scan which were produced following the Company's receipt on April 9, 1996 of
an  approvability  letter  from the U.S.  Food  and Drug  Administration.  Final
marketing clearance for this product was received on June 28, 1996.

PROPERTY AND EQUIPMENT

         Property  and  equipment  are stated at cost and are  depreciated  on a
straight-line  basis  over  the  estimated  useful  lives  (5-10  years)  of the
respective assets.

REVENUE RECOGNITION

         Payments  received under contracts to fund certain research  activities
are  recognized  as revenue in the period in which the research  activities  are
performed.   Payments   received  in  advance,   which  are  related  to  future
performance,  are deferred and recognized as revenue when the research  projects
are performed.

         Non-refundable  payments  received  under  licensing  arrangements  are
recognized as revenue in the period in which they are received.

         Revenue from the sale of diagnostic  products is recognized at the time
of shipment.

RESEARCH AND DEVELOPMENT COSTS

         Research and development costs are expensed as incurred.

INCOME TAXES

         Income taxes are accounted  for under the asset and  liability  method.
Deferred  tax  assets  and  liabilities   relate  to  the  expected  future  tax
consequences  of events that have been  recognized  in the  Company's  financial
statements  and tax  returns.  The Company  has not  recorded  any tax  benefits
associated with its net deferred tax assets.

NET LOSS PER SHARE

         Net loss per share is based upon the weighted  average number of common
shares  outstanding.  Common share equivalents,  consisting of outstanding stock
options and convertible  preferred  stock,  are not included in the computations
since the effect would be antidilutive.

USE OF ESTIMATES

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure  of  contingent  assets  and  liabilities  at the  date of  financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.

LONG-LIVED ASSETS TO BE DISPOSED OF

         In accordance with SFAS No. 121, the Company reviews  long-lived assets
for impairment  whenever events or changes in business  circumstances occur that
indicate  that the  carrying  amount of the assets may not be  recoverable.  The
Company  assesses the  recoverability  of long-lived  assets held and to be used
based on undiscounted  cash flows,  and measures the  impairment,  if any, using
discounted  cash  flows.  Adoption of SFAS No. 121 in fiscal 1997 did not have a
material  impact on the Company's  consolidated  financial  position,  operating
results or cash flows.

EMPLOYEE STOCK OPTIONS

         Employee  stock options are granted with an exercise price equal to the
market  price and,  therefore,  compensation  expense is not  recognized  on the
issuance of employee stock options.  Effective July 1, 1996, the Company adopted
the  disclosure   provisions  of  SFAS  No.  123,   ACCOUNTING  FOR  STOCK-BASED
COMPENSATION.  For the fair value of the employee stock options issued, see Note
7.

FINANCIAL INSTRUMENTS

         The carrying amounts of cash, marketable securities,  and other current
assets and  current  liabilities  approximate  fair value due to the  short-term
maturity of these instruments.

3.       MARKETABLE SECURITIES

         The Company  classifies  securities for which there is not the positive
intent  and  ability to hold to  maturity  as  available-for-sale,  and they are
carried  at fair  value.  Unrealized  holding  gains and  losses  on  securities
classified  as  available-for-sale  are  carried  as  a  separate  component  of
stockholders' equity. The Company considers all of its current investments to be
available-for-sale.  Consequently,  the Company has  recognized  an  approximate
$1,000  unrealized  holding  loss  and a  $6,000  unrealized  holding  loss as a
separate  component  of  stockholders'  equity  as of June 30,  1997  and  1996,
respectively.  Marketable  securities  at June 30, 1997 and 1996  consist of the
following:

Note 10).

7.       STOCKHOLDERS' EQUITY

         The Certificate of Incorporation of the Company  authorizes  10,000,000
shares of preferred  stock at $.01 par value per share.  The preferred stock may
be issued from time to time in one or more series,  with such distinctive serial
designations,  rights and  preferences  as shall be  determined  by the Board of
Directors.

         On  September  29,  1995,  the Company  completed  an equity  financing
pursuant to  Regulation S under the  Securities  Act of 1933  ("Regulation  S"),
pursuant  to  which  several  foreign  investors  purchased  200,000  shares  of
non-dividend  paying  Series  C  Convertible  Preferred  Stock  (the  "Series  C
Preferred") for $10,000,000. The terms of the transaction allowed the investors,
at their  discretion,  to convert  the  Series C  Preferred  into  shares of the
Company's  common stock during a twenty-two  month period beginning in September
1995, at pre-determined discounts from the average market

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

price per share over a 30-day trading period surrounding the date of conversion.
As of June 30, 1997, all 200,000 shares of Series C Preferred had been converted
into 1,538,687 shares of the Company's common stock.

         On June 27, 1996, the Company completed an equity financing pursuant to
Regulation S,  pursuant to which several  foreign  investors  purchased  200,000
shares of 5% Series D Convertible Preferred Stock (the "Series D Preferred") for
$10,000,000.  The  terms of the  transaction  allowed  the  investors,  at their
discretion,  to convert  the Series D  Preferred  into  shares of the  Company's
common stock during a  twenty-four  month period  beginning in June,  1996, at a
price equal to 89% of the average  market price per share over a 20-day  trading
period  surrounding the date of conversion.  As of June 30, 1997, 195,001 shares
of Series D Preferred had been converted into 1,733,439  shares of the Company's
common stock. In August,  1997, the remaining 4,999 shares of Series D Preferred
were converted into 62,332 shares of common stock.

         Under the terms of the  Company's  1983 Stock  Option,  as amended (the
"1983  Plan"),  stock options were granted to employees and members of the Board
of  Directors,  as  determined  by the  Compensation  Committee  of the Board of
Directors,  at fair market value,  become exercisable at 25% per year on each of
the first through fourth  anniversaries  of the date of grant,  and terminate if
not exercised within ten years. In June,  1993, the 1983 Plan expired,  although
options granted under the 1983 plan which have not terminated may continue to be
exercised. On November 5, 1992, at the Company's Annual Meeting of Stockholders,
adoption of the Company's 1992 Stock Option Plan (the "1992 Plan") was ratified.
The basic  terms of the 1992 Plan are  substantially  similar to those under the
Company's  1983 Plan.  Under the 1992 Plan,  3,000,000  shares  were  originally
reserved for possible future  issuance upon exercise of stock options,  of which
962,975  were still  available  at June 30, 1997 for future  grant.  At June 30,
1997,  3,127,125  shares of common  stock  were  reserved  for  possible  future
issuance  upon  exercise of stock  options  outstanding  and future stock option
grants.

         Pursuant to the terms of the 1992 Plan,  each  outside  Director of the
Company who was a Director on July 1 is granted,  on the first  business  day of
July of each year, an option to purchase  10,000 shares of the Company's  common
stock,  subject to reduction if such  individual was a Director for less than 12
months, at fair market value at the date of grant. On July 1, 1997, 40,000 stock
options  were  granted to these  Directors,  and on June 25,  1997,  the Company
granted 10,000 stock options to a Director who joined the Board on such date.

         On April 11, 1995, the Compensation Committee of the Board of Directors
granted the Company's  employees the  opportunity  to terminate  their  existing
options and receive new  options at fair market  value of the  Company's  common
stock on  April  11,  1995,  with a  corresponding  recommencement  of  vesting.
Accordingly,  options to purchase  790,000  shares were  terminated and an equal
number of new options were issued, which is reflected in the following table.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         The Company has adopted the disclosure-only provisions of SFAS No. 123,
ACCOUNTING  FOR  STOCK-BASED  COMPENSATION,  and  applies  APB Opinion No. 25 in
accounting for its plans and, accordingly,  has not recognized compensation cost
for stock option plans and stock purchase plans in its financial statements. Had
the Company  determined  compensation  cost based on the fair value at the grant
date  consistent  with the  provisions of SFAS 123, the Company's net loss would
have been changed to the pro forma amounts indicated below:

- --------------------------------------------------------------------------------
                                                 1997             1996

Net loss-pro forma                            14,225,532       13,463,193
Net loss per share-as reported                       .39              .40
Net loss per share-pro forma                         .40              .41
- --------------------------------------------------------------------------------

         The  fair  value  of the  stock  options  granted  in 1997  and 1996 is
estimated at grant date using the  Black-Scholes  option-pricing  model with the
following weighted average  assumptions for 1997 and 1996; dividend yield of 0%;
expected  volatility  of 42%; a risk-free  interest  rate of 6.5%;  and expected
lives of 9.9 years.

         The pro forma  effects on net income  (loss)  and  earnings  (loss) per
share for 1997 and 1996 may not be  representative  of the pro forma  effects in
future years since compensation cost is allocated on a straight-line  basis over
the vesting periods of the grants, which extends beyond the reported years.

8.       INCOME TAXES

         The Company utilizes SFAS No. 109 to account for income taxes. Pursuant
to the accounting standard,  the tax effects of temporary  differences that give
rise to significant portions of the Company's deferred tax assets as of June 30,
1997 and 1996 are presented below:


                                           1997            1996
                                       ------------    ------------
Deferred tax assets:

   Net operating loss carry forwards   $ 29,210,000    $ 24,362,000
   Research and development credits       3,830,000       3,253,000
   Property and equipment                   500,000         293,000
   Other                                    565,000         422,000
                                       ------------    ------------

Total                                    34,105,000      28,330,000

Valuation allowance                     (34,105,000)    (28,330,000)
                                       ------------    ------------
Net deferred taxes                     $         --    $         --
                                       ============    ============ 


         The valuation allowances for fiscal years 1997, 1996 and 1995 have been
applied to offset the deferred tax assets in recognition of the uncertainty that
such tax benefits  will be realized.  The  valuation  allowances  as of June 30,
1997, 1996 and 1995 include  $5,775,000,  $6,250,000 and $4,851,000  relating to
fiscal years 1997, 1996 and 1995 operations, respectively.

         At June  30,  1997,  the  Company  has  available  net  operating  loss
carryforwards  for  federal  income  tax  reporting  purposes  of  approximately
$73,845,000  which  expire  beginning  in fiscal year 1998.  The Company made no
payments of federal or state  income taxes  during  fiscal years 1997,  1996 and
1995.

9.       RELATED-PARTY TRANSACTIONS

         The  Center  for  Molecular  Medicine  and  Immunology  ("CMMI")  is  a
not-for-profit  corporation  established  in 1983 by Dr.  David  M.  Goldenberg,
Chairman of the Board,  Chief Executive Officer and the major shareholder of the
Company. CMMI is devoted primarily to cancer research.



                                       41
<PAGE>


             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         Dr. Goldenberg currently serves as the President of CMMI pursuant to an
employment agreement and devotes  substantially more of his working time to CMMI
than to the Company. Allocations between CMMI and the Company regarding research
projects  are  overseen  by the  Board  of  Trustees  of CMMI  and the  Board of
Directors  of the  Company,  excluding  Dr.  Goldenberg,  to minimize  potential
conflicts of interest.  Certain  employees of CMMI serve as  consultants  to the
Company.

         CMMI is currently  conducting basic research and patient evaluations in
a number of areas of potential  interest to the Company.  Effective July,  1995,
the Company amended its license  agreement with CMMI to assist CMMI in complying
with  Internal  Revenue  Service  criteria  for  its  then  recently   completed
tax-exempt  financing.  Under the original terms of the license  agreement,  the
Company had the right to an  exclusive,  worldwide  license to  manufacture  and
market  potential  products  developed by CMMI (other than those funded by third
parties) for specified royalty payments and on other specified terms.  Under the
amended license agreement,  the Company maintains the right of first negotiation
to obtain  exclusive,  worldwide  licenses from CMMI to  manufacture  and market
potential  products and technology  covered by the license agreement under terms
representing  fair market  price,  to be  determined  at the time the license is
obtained.  The Company  retains  licensing  rights to inventions made during the
term of the agreement for a period of five years from the time of disclosure.

         The amended license agreement terminates on December 31, 1999, with the
Company having the right to seek good-faith  negotiation to extend the agreement
for an additional  five-year period.  Prior to amendment,  the license agreement
terminated on December 11, 2010, with the Company having the right to extend the
agreement for two additional  five-year  periods with  specified  minimum annual
royalties to be paid during these two periods.

         The Company has reimbursed CMMI for expenses  incurred on behalf of the
Company,  including  amounts  incurred  pursuant to research  contracts,  in the
amount of approximately $69,000, $64,000 and $57,000 during the years ended June
30,  1997,  1996 and 1995,  respectively.  The Company also  provides  CMMI with
laboratory materials and supplies in connection with research conducted in areas
of potential interest to the Company at no cost to CMMI.

         During  the years  ended  June 30,  1997,  1996 and 1995,  the Board of
Directors of the Company  authorized  grants to CMMI of  $200,000,  $200,000 and
$300,000, respectively, to support research and clinical work being performed at
CMMI, such grants to be expended in a manner deemed  appropriate by the Board of
Trustees of CMMI.  Pursuant to a collaborative  research and license  agreement,
dated as of January 21,  1997,  between  the  Company and CMMI,  the Company has
agreed to pay CMMI an annual license fee of $200,000.

10.      LICENSE AND DISTRIBUTION AGREEMENTS

         On August 2, 1995,  the  Company  announced  that its  Development  and
License Agreement with Pharmacia,  Inc. (which  subsequently  became Pharmacia &
Upjohn Inc.--"Pharmacia") was terminated and that the Company regained the North
American  marketing and selling  rights for CEA-Scan.  The Company and Pharmacia
were subsequently  unable to agree on the amount of a final payment by Pharmacia
to the Company to satisfy Pharmacia's remaining obligations.  In June, 1996, the
Company  filed  a  claim  against  Pharmacia  before  the  American  Arbitration
Association,  claiming  damages for breach of contract and fiduciary duty in the
amount of $60 million plus punitive damages.  Payments  previously received from
Pharmacia to fund  ongoing  clinical  trials for CEA-Scan are being  recorded as
income as the trials are conducted.

         In March,  1995,  the Company  entered  into a license  agreement  with
Mallinckrodt  Medical  (Mallinckrodt),  pursuant to which Mallinckrodt  markets,
sells and  distributes  CEA-Scan  throughout  Western  Europe  and in  specified
Eastern  European  countries,  subject to receipt of regulatory  approval in the
specified countries.  The Company manufactures  CEA-Scan, for which Mallinckrodt
pays the Company a pre-determined percentage of the net selling price.

         In April,  1996, the Company entered into a Marketing and  Distribution
Agreement  with  Mallinckrodt  Medical,  Inc.,  pursuant  to which  Mallinckrodt
Medical,  Inc.  markets,  sells and  distributes  CEA-Scan for use in colorectal
cancer diagnostic imaging in the U.S. on a consignment basis, and is required to
commit financial resources to this effort. The Company retains manufacturing and
co-promotional  rights, pays Mallinckrodt  Medical, Inc. a pre-determined amount
or  percentage  of the net selling  price,  and is allowed to commit  additional
financial  resources  to  promotional  activities.   The  Company  is  currently
attempting to resolve a number of outstanding issues with Mallinckrodt under the
U.S. and European  marketing and  distribution  agreements  for CEA-Scan.  It is
unclear at this time what the  ultimate  resolution  of these issues will be and
the effect, if any, on future  performance by both parties under the agreements.
The Company has recently entered into an agreement with MMD Specialty  Services,
Inc. ("MMD") pursuant to which MMD will provide the Company,  during fiscal year
1998,  with a  full-time  oncology  sales  force for the  marketing  and sale of
CEA-Scan in the United States.

11.      COMMITMENTS AND CONTINGENCIES

         On November 1, 1993,  the Company  and Dr.  Goldenberg  entered  into a
five-year  employment  agreement (the "Agreement")  with an additional  one-year
assured renewal and thereafter  automatically  renewable for additional one-year
periods  unless  terminated  by either party as provided in the  Agreement.  Dr.
Goldenberg will receive an annual base salary of not less than $220,000, subject
to increases as determined by the Board of  Directors.  Effective  July 1, 1997,
the  Board of  Directors  increased  Dr.  Goldenberg's  annual  base  salary  to
$265,000.


                                       43
<PAGE>

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         Pursuant to the Agreement, Dr. Goldenberg may engage in other business,
general  investment and scientific  activities,  provided such activities do not
materially  interfere with the performance of any of his  obligations  under the
Agreement,  allowing for those  activities  he presently  performs for CMMI (see
Note 9). The  Agreement  extends the  ownership  rights of the Company,  with an
obligation  to  diligently  pursue  all  ideas,  discoveries,  developments  and
products,  in the entire  medical field,  which,  at any time during his past or
continuing  employment  by the Company  (but not when  performing  services  for
CMMI), Dr. Goldenberg has made or conceived or hereafter makes or conceives,  or
the making or conception of which he has materially  contributed to or hereafter
contributes  to,  all as  defined  in the  Agreement  (collectively  "Goldenberg
Discoveries").

         Further,  pursuant  to the  Agreement,  Dr.  Goldenberg  will  receive,
subject to certain  restrictions,  incentive  compensation  of 0.5% on the first
$75,000,000  of all  defined  annual net revenue of the Company and 0.25% on all
such  annual net  revenue in excess  thereof  (collectively  "Revenue  Incentive
Compensation").  With respect to the period in which Dr.  Goldenberg is entitled
to receive Revenue Incentive  Compensation on any given products,  it will be in
lieu of any other percentage compensation based on sales or revenue due him with
respect to such products under this Agreement or the existing License  Agreement
between the Company and Dr. Goldenberg. With respect to any periods in which Dr.
Goldenberg is not receiving such Revenue Incentive Compensation for any products
covered  by  patented  Goldenberg   Discoveries  or  by  certain  defined  prior
inventions  of Dr.  Goldenberg,  he will receive 0.5% on  cumulative  annual net
sales of royalties,  certain equivalents thereof, and, to the extent approved by
the Board, other consideration  received by the Company for such products, up to
a cumulative  annual aggregate of $75,000,000 and 0.25% on any cumulative annual
aggregate  in excess  of  $75,000,000  (collectively  "Incentive  Payments").  A
$100,000  annual  minimum  payment  will be paid in the  aggregate  against  all
Revenue  Incentive  Compensation and Royalty Payments and any payments under the
License  Agreement.  Dr.  Goldenberg will also receive a percent,  not less than
20%, to be  determined by the Board,  of net  consideration  (including  license
fees)  which the  Company  receives  for any  disposition,  by sale,  license or
otherwise  (discussions  directed  to  which  commence  during  the  term of his
employment  plus two years),  of any defined  Undeveloped  Assets of the Company
which are not budgeted as part of the Company's strategic plan.

         On February 1, 1994, the Company entered into a master lease agreement,
which  was  subsequently  amended,  pursuant  to which  the  Company  may  lease
equipment  for  research,  development  and  manufacturing  purposes  having  an
aggregate  acquisition cost of up to $2,200,000.  The basic lease payments under
the master  lease  agreement  are  determined  based on current  market rates of
interest at the inception of each equipment schedule  take-down,  and payable in
monthly  installments over a four-year period.  The lease agreement  contains an
early purchase option, at an amount that is deemed to be fair value, exercisable
no later  than  ninety  days  before the  thirty-sixth  installment  is due.  On
November  1, 1996,  December 9, 1996,  and April 1, 1997 the  Company  exercised
early purchase  options on equipment leased on February 14, 1994, April 1, 1994,
and June 1, 1994, respectively.

                                       44
<PAGE>

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

         Under the lease agreement,  continued compliance with certain financial
ratios is required and, in the event of default, the Company will be required to
provide  an  irrevocable  letter  of  credit  which  is  generally  equal to the
outstanding balance of lease payments due at the time of default. As of June 30,
1997, the Company has leased equipment with a cost basis aggregating  $1,247,000
under the master lease agreement and recorded lease expense for fiscal year 1997
of $497,000.

         The Company is obligated  under an operating  lease for facilities used
for  research  and  development,  manufacturing  and  office  space.  The  lease
currently expires in May, 1999, with the latter containing renewal provisions as
specified in the respective  lease. The lease expiring in May, 1999 provides for
escalating lease payments and an option to purchase the facility, exercisable by
the  Company  any time  after  December,  1993,  subject  to  certain  terms and
conditions as specified in the lease. Lease expense was approximately  $428,000,
$453,000 and $495,000 in fiscal years 1997, 1996 and 1995, respectively. Minimum
lease commitments for facilities and equipment are as follows:

                 1998 ...........................   $819,000
                 1999 ...........................   $705,000
                 Thereafter .....................   $155,000


         The Company is involved in various claims and litigation arising in the
normal course of business.  Management  believes that the outcome of such claims
and  litigation  will  not  have a  material  adverse  effect  on the  Company's
financial position and results of operations.

To the Board of Directors and Stockholders of Immunomedics, Inc.:

         We  have  audited  the  accompanying  consolidated  balance  sheets  of

each  of the  years  in  the  three-year  period  ended  June  30,  1997.  These
consolidated  financial  statements  are  the  responsibility  of the  Company's
management.  Our  responsibility is to express an opinion on these  consolidated
financial statements based on our audits.

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

         In our opinion, the consolidated financial statements referred to above
present  fairly,   in  all  material   respects,   the  financial   position  of
Immunomedics,  Inc.  as of  June  30,  1997  and  1996,  and the  result  of its
operations  and its cash  flows for each of the years in the  three-year  period

principles.

5.   Independent Contractor - Status of Personnel Employed by CONSULTANT

     This Agreement does not constitute CONSULTANT as the employee, agent
     (except to the extent expressly set forth herein) or legal representative
     of IMMUNOMEDICS for any purpose whatsoever; and the relationship of
     CONSULTANT is that of an independent contractor to IMMUNOMEDICS. In this
     regard, CONSULTANT agrees that CONSULTANT shall:


               i.  not create, incur or commit any liability or obligation for
                   IMMUNOMEDICS without the express prior written consent of
                   IMMUNOMEDICS. The final acceptance of any sales or other
                   agreement for PRODUCTS rests solely with IMMUNOMEDICS.
                   IMMUNOMEDICS, in its sole discretion, may refuse or reject
                   any sale or request for any PRODUCT (as defined in Exhibit 1
                   Section 1), cancel any sale or agreement for any PRODUCT,
                   either in whole or in part, before, during or after the
                   acceptance thereof, and/or consent to the modification or
                   variance of any agreement with respect thereto, in each case
                   without the consent of CONSULTANT.


              ii.  adhere strictly to and be governed by the policies of
                   IMMUNOMEDICS regarding the selling of IMMUNOMEDICS' PRODUCTS
                   as well as other policies of IMMUNOMEDICS to the extent
                   applicable to CONSULTANT. IMMUNOMEDICS expressly reserves the
                   right to change such policies at any time and from time to
                   time, without the consent of CONSULTANT, provided that any
                   change in such policies should be promptly communicated to
                   CONSULTANT.

                                                                          Page 3

            iii.   use only such forms, records and printed matter as may be
                   furnished by IMMUNOMEDICS and keep, in a manner reasonably
                   satisfactory to IMMUNOMEDICS, accurate and complete records;
                   and immediately transmit to IMMUNOMEDICS all original
                   communications received from customers and potential
                   customers of IMMUNOMEDICS. All such records shall be and
                   remain the property of IMMUNOMEDICS. CONSULTANT agrees to
                   supply to IMMUNOMEDICS all other information with respect to
                   any of its activities on behalf of IMMUNOMEDICS as
                   IMMUNOMEDICS may request.

             iv.   have all checks and drafts of money due to IMMUNOMEDICS made
                   payable to IMMUNOMEDICS and instruct all customers to remit
                   their payments directly to IMMUNOMEDICS. If, for any reason,
                   any such payments are received by CONSULTANT, it shall report
                   and remit such payments immediately to IMMUNOMEDICS. All
                   billings shall be made by IMMUNOMEDICS. Credit on all
                   accounts shall, in all instances, be subject to approval by
                   IMMUNOMEDICS.

              v.   be responsible for any and all of its employees' acts,
                   omissions to act, representations and misrepresentations,
                   including such actions, if any, which may result in damage or
                   injury to IMMUNOMEDICS.

             vi.   comply with all laws and regulations, federal, state and
                   local.

            vii.   pay all of its own expenses (including, without limitation,
                   the compensation and benefits to CONSULTANT's REGIONAL SALES
                   SPECIALISTS set forth on Exhibit 4 to this Agreement) except
                   to the extent reimbursed by IMMUNOMEDICS as provided in this
                   Agreement.

           viii.   accept full and exclusive liability for the payment of any
                   and all taxes, contributions or other sums payable for
                   worker's compensation and unemployment compensation or
                   insurance and old age retirement benefits as well as all
                   other federal, state and local taxes payable by reason of
                   CONSULTANT's activities.

             ix.   pay, when due, to all appropriate insurance carriers and
                   governmental agencies such amounts as shall be required by
                   any mandatory employee insurance provisions of law (such as,
                   if applicable, medical and worker's compensation) and by any
                   governmental agencies based upon the amounts paid to its
                   employees (such as FICA, medicare, unemployment insurance,
                   etc.), as well as any amounts of employee taxes required to
                   be withheld and paid on behalf of any of its employees,
                   including, without limitation, CONSULTANT's REGIONAL SALES
                   SPECIALISTS.

              x.   in employing any personnel, advise such personnel that they
                   are employees of CONSULTANT, are not to consider themselves
                   to be employees of IMMUNOMEDICS and that in employing such
                   personnel, CONSULTANT is acting individually and not as an
                   agent for IMMUNOMEDICS; and such personnel are to be
                   compensated solely by CONSULTANT.

                                                                          Page 4

                   and in accordance with procedures established by IMMUNOMEDICS
                   from time to time; and furnish to IMMUNOMEDICS such other
                   information with respect to such activities as IMMUNOMEDICS
                   may reasonably request.

     whatsoever for withholding or paying such taxes for or on behalf of
     CONSULTANT. CONSULTANT further agrees to defend, indemnify and hold
     IMMUNOMEDICS harmless from and against any and all damages, losses,
     expenses, or penalties arising from or in connection with any claim brought
     by any federal, state or local taxing authority with regard to CONSULTANT's
     failure to withhold or pay required taxes or failure to file forms required
     to be filed by CONSULTANT with regard to compensation paid to CONSULTANT by
     IMMUNOMEDICS pursuant to this Agreement.

8.   Insurance

9.   Indemnification
     ---------------

     9.1      IMMUNOMEDICS shall indemnify and hold CONSULTANT and its agents,
              directors, officers and employees, harmless from and against any
              and all claims made against it or them by third parties,
              regardless of the form in which such claim is made, for losses,
              costs, damages, liabilities, fees or expenses, including
              reasonable attorney's fees, relating to the manufacture, use or
              sale of the PRODUCTS, including, without limitation, PRODUCTS
              liability claims and claims relating to the advertising and
              promotion of the PRODUCTS except for claims made as the result of
              the CONSULTANT REGIONAL SALES SPECIALIST representations as to
              PRODUCTS which are outside the scope of approved labeling.

     9.2      In the event of any claim against CONSULTANT or any of its agents,
              directors, officers or employees, in respect of which CONSULTANT
              or any such person is or may be entitled to an indemnity under
              this Agreement, neither CONSULTANT nor any other indemnified
              person shall make any admission but shall promptly notify
              IMMUNOMEDICS in writing of the claim and IMMUNOMEDICS shall be
              entitled but not obliged to manage and control, at its sole
              expense, the defense of the claim and its settlement. The benefit
              of any indemnity by IMMUNOMEDICS under this Agreement in respect
              of any claim shall not apply to any person if any admission made
              by that person or any failure by the person to notify IMMUNOMEDICS
              of the claim materially prejudices the defense of such claim. No
              indemnified party shall settle any claim without the prior written
              consent of the indemnifying party. CONSULTANT and all other
              indemnified persons shall, if so required by IMMUNOMEDICS,
              cooperate in all reasonable respects with IMMUNOMEDICS in the
              defense of such a claim managed by IMMUNOMEDICS and may, at any of
              their option and at their sole expense, be represented in any
              action or proceeding arising out of such claim. IMMUNOMEDICS shall
              not be liable for any litigation costs or expenses incurred by
              CONSULTANT or by any other indemnified person without
              IMMUNOMEDICS' written authorization, if such litigation is managed
              by IMMUNOMEDICS.


     9.3      The above shall not in any event apply to the extent that any
              claim, loss, cost, damage, fee, expense or liability is the result
              of any breach of this AGREEMENT by CONSULTANT or of any act or
              omission or negligence, recklessness or willful misconduct of
              CONSULTANT, its Affiliates, or their respective agents, directors,
              officers or employees.

                                                                          Page 6
<PAGE>



     9.4      CONSULTANT shall indemnify and hold IMMUNOMEDICS, its agents,
              directors, officers and employees, harmless from and against any
              and all claims made against it or them by third parties,
              regardless of the form in which such claim is made, for losses,
              costs, damages, liabilities, fees or expenses, including
              reasonable attorney's fees, to the extent that they arise out of
              or in connection with any unauthorized act or omission or
              negligence, recklessness or willful misconduct of CONSULTANT, its
              Affiliates, or their respective agents, directors, officers or
              employees in relation to any of the PRODUCTS and the services to
              be performed by CONSULTANT under or in connection with this
              Agreement.


     9.5      In the event of any claim against IMMUNOMEDICS or any of its
              agents, directors, officers or employees, in respect of which
              IMMUNOMEDICS or any such person is or may be entitled to an
              indemnity under this Agreement, neither IMMUNOMEDICS nor any other
              indemnified person shall make any admission but shall promptly
              notify CONSULTANT in writing of the claim and CONSULTANT shall be
              entitled but not obliged to manage and control, at its sole
              expense, the defense of the claim and its settlement. The benefit
              of any indemnity by CONSULTANT under this Agreement in respect of
              any claim shall not apply to any person if any admission made by
              that person or any failure by that person to notify CONSULTANT of
              the claim materially prejudices the defense of such claim. No
              indemnified party shall settle any claim without the prior written
              consent of the indemnifying party. IMMUNOMEDICS and all other
              indemnified persons shall, if so required by CONSULTANT, cooperate
              in all reasonable respects with CONSULTANT in the defense of such
              a claim managed by CONSULTANT and may, at any of their option and
              at their sole expense, be represented in any action or proceeding
              arising out of such claim. CONSULTANT shall not be liable for any
              litigation costs or expenses incurred by IMMUNOMEDICS or by any
              other indemnified person, without CONSULTANT's written
              authorization, if such litigation is managed by CONSULTANT.

                                   Exhibit 1
                                   ---------

DESCRIPTION OF SERVICES:
- ------------------------

1.   During the TERM OF THIS AGREEMENT, CONSULTANT shall locate and employ
     members of a full-time specialty oncology sales force (each such member a
     "CONSULTANT's REGIONAL SALES SPECIALIST") for the marketing and sale of
     IMMUNOMEDICS' in-vivo cancer diagnostic imaging agent known as
     "CEA-Scan(R)", and such other IMMUNOMEDICS products as may be specified by
     IMMUNOMEDICS (the "PRODUCTS"). These SALES SPECIALISTS are to be
     professional sales people with experience in Radiology, Oncology, Nuclear
     Medicine, and/or surgery. Additionally, these specialists should have
     hospital selling experience in short cycle direct sales. These SALES
     SPECIALISTS will be engaged exclusively in the marketing and sales of the
     PRODUCTS. No CONSULTANT's REGIONAL SALES SPECIALIST shall be employed by
     CONSULTANT without the prior written consent of IMMUNOMEDICS, after
     IMMUNOMEDICS shall have completed such participation in, and review of,
     CONSULTANT's proposed hiring of the CONSULTANT's REGIONAL SALES SPECIALIST
     as IMMUNOMEDICS shall deem appropriate. Upon the occurrence of the
     resignation, termination or other event making the services of any
     CONSULTANT's REGIONAL SALES SPECIALISTS unavailable, CONSULTANT shall
     notify IMMUNOMEDICS promptly of such occurrence and of CONSULTANT's plans
     for replacement of such REGIONAL SALES SPECIALIST.

2.   During the TERM OF THIS AGREEMENT CONSULTANT's REGIONAL SALES SPECIALISTS
     shall use their best efforts to sell IMMUNOMEDICS' PRODUCTS and in
     connection therewith, shall VISIT (as hereinafter defined) prospective
     customers selected by IMMUNOMEDICS and located in the target market areas
     defined by IMMUNOMEDICS. These prospective customers will include (but not
     be limited to) hospitals and clinics and may encompass a large geographical
     area and require overnight travel.

     During the TERM OF THIS AGREEMENT, CONSULTANT agrees to provide
     approximately sixteen (16) CONSULTANT's REGIONAL SALES SPECIALISTS
     supported by one (1) National Field Sales Manager. CONSULTANT's REGIONAL
     SALES SPECIALISTS will make dedicated VISITS during the TERM OF THIS
     AGREEMENT in accordance with the instructions of IMMUNOMEDICS.

     For the purposes of the Agreement, "VISIT" shall mean a face-to-face
     presentation by a CONSULTANT's REGIONAL SALES SPECIALIST, which
     presentation shall be dedicated solely to the marketing and sales of the
     PRODUCTS. The presentation must include a discussion of features and
     benefits of the PRODUCTS. As part of the VISIT, CONSULTANT's REGIONAL SALES
     SPECIALISTS shall present prospective customers solely with IMMUNOMEDICS
     provided PRODUCT literature. Also, as part of the VISIT, CONSULTANT's
     REGIONAL SALES SPECIALISTS will conduct face-to-face presentations at
     selected sites with prospective customers. VISITS shall be made (and a
     Sales Summary Report with respect to each VISIT shall be provided to
     IMMUNOMEDICS) in accordance with instructions of IMMUNOMEDICS as described
     in training and other COMMUNICATIONS and as amended from time to time.

                                                                         Page 15
<PAGE>

     During the TERM OF THIS AGREEMENT, CONSULTANT's REGIONAL SALES SPECIALISTS
     shall VISIT each of the target prospective hospitals every [*] weeks and
     each of the target prospective customers every [*] weeks. All prospective
     leads shall be contacted within [*] working days after receipt of lead from
     IMMUNOMEDICS by the REGIONAL SALES SPECIALIST.

     Within ten (10) working days following June 30, 1998 or upon the
     termination of this Agreement, whichever occurs sooner, CONSULTANT shall
     return to IMMUNOMEDICS all unused promotional and advertising materials,
     marketing plans, sales training materials, territory lists, reports, all
     equipment in good condition or good working order, and any and all other
     tangible items. CONSULTANT agrees that is shall pay to IMMUNOMEDICS an
     amount equal to the fair market value of any equipment (including without
     limited, any laptop computer) not so returned, or that IMMUNOMEDICS may set
     off such amount against any sums then owing to CONSULTANT by IMMUNOMEDICS.

3.   CONSULTANT shall ensure that no claims or representations in respect of the
     PRODUCTS or the characteristics thereof are made by or on behalf of it
     (and, in particular, by CONSULTANT's REGIONAL SALES SPECIALISTS) which do
     not represent a reasonable summary or explanation of the labeling of the
     PRODUCTS.

     During the TERM OF THIS AGREEMENT, subject to Section 11 of the Agreement,
     IMMUNOMEDICS shall provide CONSULTANT with information known to
     IMMUNOMEDICS which is relevant or appropriate, to enable CONSULTANT to
     respond promptly to questions or inquiries which are directed to CONSULTANT
     from members of the medical and paramedical professions relating to the
     PRODUCTS. CONSULTANT shall not publish, disclose or use any information
     provided to CONSULTANT by IMMUNOMEDICS pursuant to this Agreement for any
     purpose other than for the purpose of responding to such questions and
     inquiries to which CONSULTANT is otherwise unable to respond. Nothing in
     this Agreement shall be deemed to impose any obligation on CONSULTANT or
     any of its employees to make any such response which violates professional
     ethics.

4.   COMMUNICATIONS to and from CONSULTANT's employees shall be handled through
     CONSULTANT or directly by IMMUNOMEDICS as appropriate under the
     circumstances.

5.   CONSULTANT's National Field Sales Manager in charge of the program covered
     by this Agreement will be involved in the recruitment and hiring by
     CONSULTANT of competent REGIONAL SALES SPECIALISTS, and the training of the
     REGIONAL SALES SPECIALISTS. The National Field Sales Manager will attend
     the REGIONAL SALES SPECIALISTS' training meeting, ride with CONSULTANT's
     REGIONAL SALES SPECIALISTS in the field, provide monthly field reports, and
     be a resource to IMMUNOMEDICS management in regards to this program.


                                                                         Page 16
<PAGE>


6.   IMMUNOMEDICS' request, CONSULTANT will allow IMMUNOMEDICS to examine and
     audit its records, and to monitor CONSULTANT's REGIONAL SALES SPECIALISTS'
     performance at reasonable times and at IMMUNOMEDICS' sole expense.

7.   In the event IMMUNOMEDICS shall determine that any CONSULTANT's REGIONAL
     SALES SPECIALIST has violated the terms of this Agreement or should
     otherwise be removed for cause (which term shall include, without
     limitation, sales production which, in the reasonable judgment of
     IMMUNOMEDICS, is inadequate), IMMUNOMEDICS shall have the right to require
     that such CONSULTANT's REGIONAL SALES SPECIALIST be removed immediately
     from the program covered by this Agreement. CONSULTANT agrees to replace
     any such CONSULTANT's REGIONAL SALES SPECIALIST as expeditiously as
     possible.

8.   CONSULTANT agrees that its REGIONAL SALES SPECIALISTS will be available to
     attend specified IMMUNOMEDICS sales meetings and also to participate in
     discussions with IMMUNOMEDICS sales management.


                                                                         Page 17

- ----------------------------------

1.   As used herein, "CONFIDENTIAL INFORMATION" shall mean information relating
     to the business, products or services of a party (the "DISCLOSING PARTY")
     which is either non-public, confidential or proprietary in nature, whether
     in written or oral form and including summaries or notes thereof, and which
     has been disclosed to the other party hereto (the "RECEIPIENT"). Without
     limiting the generality of the foregoing, CONFIDENTIAL INFORMATION shall
     include (i) information which related to any of the PRODUCTS and its
     manufacture, sale or use, including financial statements, costs and expense
     data, production data, know-how, trade secrets, secret processes and
     formulae, technical data and reports, manufacturing and formulation data,
     or any other information relating to the PRODUCTS which is not generally
     ascertainable from public or published information, regardless of whether
     such information was provided pursuant to the terms of this Agreement, by
     request of the RECEIPIENT or in any other manner; (ii) information related
     to the PRODUCTS contained in all documents submitted in connection with
     regulatory submissions covering the PRODUCTS, and (iii) marketing and
     consumer data, including development plans, strategies and forecasts, and

2.   RECEIPIENT agrees to accept such CONFIDENTIAL INFORMATION in accordance
     with the following terms:

     a.  RECEIPIENT agrees not to disclose to anyone and to protect the
         confidentiality of any and all CONFIDENTIAL INFORMATION disclosed to it
         by the DISCLOSING PARTY under this Agreement with the exception of the
         following:

         i.   Disclosure permitted by paragraph 5, below;

         ii.  CONFIDENTIAL INFORMATION which, at the time of disclosure by the
              DISCLOSING PARTY, is generally known to the public;

         iii. CONFIDENTIAL INFORMATION which, after disclosure by the DISCLOSING
              PARTY, becomes part of the public knowledge by publication or
              otherwise, except by breach of this Agreement;

         iv.  CONFIDENTIAL INFORMATION which was in RECIPIENT's possession at
              the time of disclosure by the DISCLOSING PARTY and which was not
              acquired, directly or indirectly, from the DISCLOSING PARTY,
              provided RECEIPIENT furnishes the DISCLOSING PARTY with
              satisfactory written documentation thereof prior to any disclosure
              of such CONFIDENTIAL INFORMATION to a third party;


                                                                         Page 20
<PAGE>


         v.   CONFIDENTIAL INFORMATION which RECEIPIENT received from third
              parties who have the legal right to disclose such CONFIDENTIAL
              INFORMATION, provided such CONFIDENTIAL INFORMATION was not, to
              the knowledge of RECEIPIENT, obtained by said third parties,
              directly or indirectly, from the DISCLOSING PARTY on a
              confidential basis;

         vi.  CONFIDENTIAL INFORMATION which RECEIPIENT can verify with written
              documentation results solely from research and development by
              RECEIPIENT independent of disclosures from the DISCLOSING PARTY;
              or

         vii. CONFIDENTIAL INFORMATION required to be disclosed by applicable
              laws, regulations or judicial process provided the DISCLOSING
              PARTY received ten (10) days advance notice of such required
              disclosure in order for the DISCLOSING PARTY to oppose such
              disclosure in its discretion; provided however, if disclosure must
              be made in a period shorter than ten (10) days based on the
              receipt of an opinion of counsel by the recipient, in order to
              comply with the rules and regulations of the Security and Exchange
              Commission for the rules and regulations of any international
              exchange, then upon such advance notice as shall be practicable
              under the circumstances. RECEIPIENT will cooperate with the
              DISCLOSING PARTY's efforts to obtain a protective order or other
              appropriate remedy concerning any such disclosure. In the event
              that such a protective order or other remedy is not obtained, or
              that the DISCLOSING PARTY waives compliance with the provisions of
              this paragraph, RECEIPIENT shall furnish only that portion of the
              CONFIDENTIAL INFORMATION legally required to be disclosed and
              RECEIPIENT will exercise its best efforts to obtain reliable
              assurance that confidential treatment will be accorded the
              CONFIDENTIAL INFORMATION required to be so disclosed.

3.   RECEIPIENT agrees that it will not use the CONFIDENTIAL INFORMATION, which
     it is required hereunder to keep confidential for any purpose other than in
     connection with the marketing of the PRODUCTS in accordance with this
     Agreement (the "INTENDED PURPOSE").

4.   RECEIPIENT acknowledges that irreparable damage will result to the
     DISCLOSING PARTY if any CONFIDENTIAL INFORMATION is improperly disclosed to
     a third party or is used for any purpose other than the INTENDED PURPOSE.


                                                                         Page 21

5.   RECEIPIENT will disclose such CONFIDENTIAL INFORMATION only to such of its
     officers and employees, or its direct subsidiaries' officers and employees,
     who are directly concerned with the marketing of the PRODUCTS, and will
     advise such officers and employees, upon disclosing such CONFIDENTIAL
     INFORMATION to them, of the confidential nature thereof and require each
     such person to acknowledge in writing their receipt of a copy of this
     Confidential Information Statement and their agreement to be bound by the
     terms hereof. In addition, RECEIPIENT will take all reasonable precautions
     to prevent such CONFIDENTIAL INFORMATION from being acquired by an
     unauthorized person, firm or company, including, but not limited to, those
     that it takes to protect its own proprietary and confidential information.

6.   At any time with thirty (30) days notice, upon the request of the
     DISCLOSING PARTY, RECEIPIENT will return all documentation relating to the
     CONFIDENTIAL INFORMATION to the DISCLOSING PARTY without retaining any
     copies, summaries or notes thereof.

7.   In the event of any breach or threatened breach of this Agreement, the
     DISCLOSING PARTY shall, in addition to any other remedies which may be
     available, be entitled to injunctive and other equitable relied in any
     court of competent jurisdiction.

8.   The obligations set forth in the Confidential Information Statement shall
     be continuing and shall survive the expiration or termination of this
     Agreement for a period of five (5) years.
