                                     PART I

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 other  diseases.  Integral  to these  products  are highly  specific
monoclonal  antibodies  designed  to  deliver  radioisotopes,   chemotherapeutic
agents,  toxins,  dyes or other  substances to a specific  disease site or organ
system.

     The Company is applying its expertise in antibody  selection,  modification
and  chemistry  to  develop  therapeutic  products  for cancer  using  humanized
monoclonal  antibodies  unlabeled,  or conjugated  with  isotopes or drugs.  The
Company   conducted   a  Phase  I/II   clinical   trial  with   epratuzumab,   a
non-radioactive  non-Hodgkin's  lymphoma  ("NHL")  therapeutic.  This  trial was
designed to obtain  knowledge  about  targeting  and dosing  with the  unlabeled
humanized  form of the  monoclonal  antibody  that targets the CD22  receptor of
B-cells and B-cell  lymphomas.  The Company had advanced the  humanized  form of
epratuzumab  to Phase III  clinical  testing,  evaluating  the agent in  certain
indolent  non-Hodgkin's  lymphoma  patients.  The Company  also began a Phase II
clinical   trial  to  determine  the  safety  and  efficacy  of  epratuzumab  in
combination with Rituxan(R) (rituxamab,  IDEC Pharmaceuticals and Genentech), in
both indolent and aggressive  forms of NHL. The unlabeled CD22 antibody has been
licensed to Amgen, Inc., for further development and  commercialization in North
America and Australia (see "In Vivo" Therapeutic  Products).  In addition to the
naked  antibody,  the  Company  is  also  evaluating  epratuzumab  labeled  with
Yttrium-90 in Phase I/II clinical trials. (see "In Vivo" Therapeutic Products").
A Phase II  clinical  trial  has been  conducted  in  Germany  with  CEA-Cide(R)
(labetuzumab),  labeled with  Iodine-131,  for  treatment of patients with small
volume, inoperable, metastatic colorectal cancer. The Company also is evaluating
labetuzumab  as an unlabeled  antibody in a Phase I clinical trial in colorectal
and breast cancer patients.  The Yttrium-90 labeled labetuzumab is being studied
in a Phase I/II  clinical  trial in  patients  with  colorectal  and  pancreatic
cancers.  Labetuzumab  targets receptor sites on CEA-expressing  solid tumors of
the  breast,  lung,  digestive  and other  organ  systems.  The Company has five
product  candidates  in  pre-clinical  development:  AFP-Cide,  for liver cancer
therapy,  ProstaCide,  for prostate cancer therapy,  MelanomaCide  for malignant
melanoma  therapy,  MyelomaCide for multiple  myeloma  therapy and LeukoCide,  a
therapeutic for myeloid leukemia.

     The Company also is  developing a line of in vivo imaging  products for the
detection  of  various  cancers  and  other  diseases.  These  agents  are being
developed by the Company as companion  diagnostic  products  that may be used in
conjunction with the therapeutic  agents,  thereby providing more  comprehensive
patient  management.  The Company is  currently  licensed to market and sell two
diagnostic products, CEA-Scan(R) and LeukoScan(R).  CEA-Scan is designed for use
with other standard diagnostic  modalities for the detection of recurrent and/or
metastatic  colorectal cancer. The Company has received  regulatory  approval to
market and sell CEA-Scan from the respective  regulatory  agencies in the United
States, the 15 countries comprising the European Union and Canada. LeukoScan has
been  approved  in the  European  Union  for  the  detection  and  diagnosis  of
osteomyelitis  (bone  infection)  in  long  bones  and in  diabetic  foot  ulcer
patients.  The  Company  has  developed  and filed an  Investigational  New Drug
application  ("IND") for two other in vivo cancer imaging products:  AFP-Scan(R)
for the  detection  and  diagnosis  of liver  and germ cell  cancers,  which has
completed Phase II clinical trials, and LymphoScan(TM) for diagnosis and staging
of  non-Hodgkin's  lymphomas,  currently  in  Phase  III  clinical  trials  (see
"Products and Projects in Development").  Additionally,  there are three product
candidates in pre-clinical development: ProstaScan, MelanomaScan and MyelomaScan
for imaging prostate, malignant melanoma and multiple myeloma, respectively.

                                       1


     The Company, through its 80% owned subsidiary, IMG Technology, LLC ("IMG"),
has formed a joint  venture  (IBC  Pharmaceuticals,  LLC  ("IBC"))  with Coulter
Corporation  ("Beckman  Coulter") for the purpose of developing  targeted cancer
therapeutics.  The joint venture is focused on investigating pre-targeting using
bi-specific antibodies.  Bi-specific antibodies are able to bind both an antigen
as well as a  carrier  to  which  is  attached  to a  chemotherapeutic  agent or
radioisotope.  Initially,  the  bi-specific  antibody is injected and allowed to
bind to its  specific  antigen.  After the  bi-specific  antibody  has bound the
antigen,  the carrier with its attached therapeutic agent is administered to the
patient.  The carrier then binds to the antibody  that has remained  attached to
the antigen.  This method has the advantage of allowing the unbound carrier with
its attached  therapeutic  agent to be rapidly  cleared from the patient's blood
and tissue, resulting in the delivery of more of the therapeutic agent to cancer
cells than to normal cells. The promising  results from animal studies have been
confirmed  by  initial  clinical  studies  conducted  by  IBC in  France,  using
Iodine-131 as the therapeutic agent.

     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 B.V., with offices located in Hillegom, The Netherlands,  to assist
the Company in managing sales and marketing  efforts and  coordinating  clinical
trials in Europe.

Products and Projects in Development

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   anti-cancer   products,   principally   with  a  technique   called
radioimmunotherapy.  This technique may deliver radiolabeled  therapeutic agents
to tumor sites more selectively  than current  radiation  therapy  technologies,
while possibly  minimizing  debilitating  side effects.  The Company completed a
Phase I clinical trial with the murine form of its non-Hodgkin's B-cell lymphoma
proposed  therapeutic  product,  epratuzumab,  at the  University  of  Nebraska.
Epratuzumab  is a  monoclonal  antibody,  highly  specific in  targeting  B-cell
lymphomas,  labeled with the radioisotope  Iodine-131.  In this Phase I clinical
trial of  epratzumab,  several  patients,  all of whom were  late-stage and were
unresponsive  to  other   therapies,   experienced   varying  degrees  of  tumor
regression.  Reversible  bone marrow  toxicity also was observed.  By conducting
this trial,  the Company  increased  its  knowledge  of antibody  targeting  and
dosage. The Company is completing the evaluation of epratuzumab in its humanized
form and radiolabeled  with Yttrium-90 in Phase I/II studies at several sites in
the U.S. and Europe.  The Company has also tested the  unlabeled  (cold) form of
epratuzumab  in a Phase I/II trial of about 115 patients  with both indolent and
aggressive  forms  of  NHL,  and has  found  the  agent  to  show  good  safety,
tolerability, and evidence of antitumor activity.  Importantly,  epratuzumab may
be  infused  in as little as  fifteen  minutes  without  compromising  safety or
efficacy.  An  agreement  to enter  into  Phase III  clinical  trials in certain
indolent non-Hodgkin's lymphoma patients had been reached by the Company and the
Food and Drug Administration  ("FDA"). On December 17, 2000, the Company entered
into a Development and License Agreement with Amgen, Inc. to license epratuzumab
to Amgen in North  America  and  Australia.  Under  this  agreement,  Amgen  has
undertaken the final development of epratuzumab in this territory, including the
Phase III trial, as well as other trials and research.  In exchange for granting
this license, the Company received an upfront payment of $ 18 million from Amgen
on February 1, 2001.  The  agreement  also provides that the Company may receive
additional milestone payments totaling $ 65 million depending on the progress of
the product's  development.  In addition, the Company could receive royalties on
net sales of the product by Amgen and one-time sales milestone  payments ranging
from $ 50 million  to $ 225  million  if and when  annual net sales  reach $ 500
million to $ 1 billion.  Additional compensation would be payable to the Company
under the agreement for each  second-generation  product  developed by Amgen, if
any, using the licensed antibody.

                                       2


     The Company plans to continue the  development of epratuzumab  either alone
or  with a  partner  in the  geographic  regions  that  are not  covered  by the
agreement with Amgen. The Company also plans to continue the clinical evaluation
of the Yttrium-90 radiolabeled form of this CD22 antibody in Phase I/II clinical
trials that are being  conducted in the U.S. and Europe.  The trials examine the
safety and efficacy of fractionated and single doses of Yttrium-90  labeled CD22
antibody in patients with indolent or aggressive forms of non-Hodgkin's lymphoma
who have a relapse of this disease following standard chemotherapy.

     In February,  1999,  the Company  entered into a  Cooperative  Research and
Development  Agreement  ("CRADA")  with the National  Cancer  Institute  ("NCI")
covering the development and use of its humanized  lymphoma antibody (as well as
certain other antibodies)  conjugated to recombinant  ribonucleases (RNase) as a
potential new anticancer agent. The Company  contributed its humanized  lymphoma
antibody and funding,  and the NCI contributed  the RNase and other  technology.
The antibody  delivers the RNase to the cancer cell where it destroys the cell's
ribonucleic acid (RNA),  which is essential for cell division.  In May 1999, the
Company entered into a Clinical  Trials  Agreement (CTA) with the Cancer Therapy
Evaluation  Program  (CTEP) of the Division of Cancer  Treatment  and  Diagnosis
(DCTD) at the NCI. The agreement serves as the basis for the  co-development  of
epratuzumab by the Company and DCTD. Following the consummation of the licensing
agreement with Amgen, this CTA was terminated by the Company.

     A Phase II clinical trial is being completed with the Company's  colorectal
cancer therapeutic,  CEA-Cide (labetuzumab) labeled with Iodine-131.  This trial
is being conducted in Europe in patients with metastatic  colorectal  cancer who
failed  chemotherapy.  The Company continues to enter patients into a Phase I/II
clinical  trial with its  humanized  CEA  antibody,  unlabeled  and labeled with
Yttrium-90.  These trials will evaluate the safety of these products in patients
with  colorectal,  pancreatic  and  breast  cancer.  The  Company  is  currently
conducting, in collaboration with several academic or research centers, research
on humanized forms of targeting  antibodies,  alternative  radioisotopes and new
conjugation methods (see "Research Programs").

     The  Company  has five  product  candidates  in  pre-clinical  development:
AFP-Cide,  for liver cancer  therapy,  ProstaCide,  for prostate cancer therapy,
MelanomaCide for malignant  melanoma  therapy,  MyelomaCide for multiple myeloma
therapy and LeukoCide, a potential therapeutic for myeloid leukemia.

In Vivo Imaging Products

     The Company's in vivo imaging products utilize radioimmunodetection,  which
involves  injecting a patient  with a  radioisotope  linked 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 detect
and display radioisotope  concentrations,  revealing the presence,  location and
approximate size of the site of disease.

                                       3


     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.  Finally,  technetium-99m  labeled  antibody
fragments not taken up by tumors are quickly excreted via the kidneys, enhancing
tumor-to-background ratios in other regions.

     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  (arcitumomab)  for use in
conjunction with other standard  diagnostic  modalities for the detection of the
presence,  location and extent of recurrent and/or metastatic colorectal cancer.
On October 4, 1996,  CEA-Scan also was approved by the European  Commission  for
the same  indication.  On September 16, 1997,  the Company  received a notice of
compliance  from the Health  Protection  Branch ("HPB")  permitting it to market
CEA-Scan in Canada for recurrent and metastatic  colorectal cancer. In addition,
the Company has six other in vivo  imaging  products or  indications  in various
stages of clinical  testing and  regulatory  review by the FDA,  five for cancer
imaging  (CEA-Scan for lung and breast cancer,  AFP-Scan for liver and germ cell
cancer,  and  LymphoScan  for  non-Hodgkin's   lymphoma)  and  one  for  imaging
infectious  diseases   (LeukoScan).   Additionally,   there  are  three  product
candidates in pre-clinical development; ProstaScan, MelanomaScan and MyelomaScan
for imaging prostate, malignant melanoma and multiple myeloma, respectively.

     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 in their  tumors.  As part of receiving  FDA
approval  for  CEA-Scan,  the  Company  has agreed to conduct  Phase IV clinical
studies to evaluate the product following  re-administration.  Phase II clinical
trials for breast cancer imaging have been completed, results of which have been
published in the July 2000 issue of Cancer.

     LeukoScan  (sulesomab) is a monoclonal antibody fragment that seeks out and
binds to granulocytes  (white blood cells)  associated  with a potentially  wide
range of infectious and inflammatory 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 Biologics  License
Application  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.  There  have  been no  subsequent
substantive  regulatory  actions  taken  by the  Company  with  respect  to this
product.  A New Drug Submission for the same indications as in the U.S. is under
review  with the HPB in Canada  (filed on March 24,  1998),  and in  Switzerland
(filed in September, 1998).

                                       4


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

     --   LymphoScan,  employing an antibody  capable of targeting an antigen on
          non- Hodgkin's  B-cell  lymphomas (Phase III clinical trials have been
          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 have been completed).

Research Programs

     The Company incurred approximately $10,264,000, $8,670,000 and $10,100,000,
in total research and development expense during its fiscal years ended June 30,
2001, 2000 and 1999, 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  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 certain 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.

     During the past fiscal  year,  the  Company,  in  collaboration  with other
investigators,  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. The anticancer humanized antibodies are about 95% human
and have shown good uptake in the patients' tumors.  The Company is now focusing
on the study of these  humanized  monoclonal  antibodies,  unlabeled and labeled
with  Yttrium-90,  in patients with the  appropriate  target  tumors  (discussed
below).

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 that is known not to  interfere  with antigen  binding.  The Company
also is continuing  to  investigate  "pre-targeting"on  its own and through IBC,
using bi-specific  antibodies.  In the pre-targeting  technique,  an antibody is
administered  first and then followed by a separate  radionuclide or therapeutic
drug  administration.  Secondary  recognition  groups are  attached,  one to the
targeting  antibody and the other to the radionuclide or therapeutic  drug, such
that the  radionuclide or drug 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.

                                       5


Peptides

     During fiscal year 2001, the Company  continued to improve its  proprietary
methods for  technetium-99m  radiolabeling of peptides,  which were 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  somatostatin  and  has
demonstrated  reagent utility in  pre-clinical in vivo models.  In related work,
similar  synthetic  methods  have  also  been  used to  prepare  chelate-peptide
conjugates  that can be  radiolabeled  with  Indium-111 and Yttrium-90  which is
being applied to the  bi-specific  pre-targeting  technology that the Company is
developing through IBC.

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.  The Company has remained
in contact with these surgeons,  one of whom reported to the Society of Surgical
Oncology on a prospective study of CEA-Scan imaging and probe-guided  surgery in
twenty (20) patients.  That study concluded that the probe and CEA-Scan provided
useful  new  information  in 7  of  20  patients,  encouraging  more  aggressive
operative  intervention and  postoperative  care,  including  chemotherapy.  The
Company is  conducting a Phase IV clinical  trial  evaluating  CEA-Scan  used in
conjunction  with an  intraoperative  probe in patients  undergoing  surgery for
colorectal  cancer. A U.S. patent was issued in 1990 to the Company for this and
for laser and endoscopic applications.  In March 2000, the Company was awarded a
U.S.  patent  covering the use of very small portions of antibodies that bind to
certain  diseased  tissues,  potentially  allowing for improved  intraoperative,
intravascular and endoscopic detection.

Government Grants

     The  Company  is  continuing  the second  year of work on a Small  Business
Innovation  Research  ("SBIR") Phase II grant from the National Cancer Institute
("NCI"),  with funding of $800,000 over two years. The work performed under this
grant  will  investigate  the use of  bispecific  antibodies  for  the  enhanced
delivery of  radioimmunotherapy  to colon tumors.  Preliminary  results from the
Phase I SBIR work suggest  that the  approach  may lead to improved  therapeutic
ratios (the amount of radiation deposited in a tumor versus the amount deposited
in normal tissues).  The injected  radioactivity either binds to the pretargeted
bispecific antibody at the tumor, or it is rapidly and harmlessly excreted.  The
method  under   development  by  the  Company  is  applicable  to  any  type  of
radioimmunotherapy.

     The Company is also  completing  the second  year of another  SBIR Phase II
grant from NCI,  originally  awarded in September  1999, at a budget of $750,000
over two years. This project may result in an advanced  radioimmunotherapy agent
for the treatment of breast cancer.

     The Company, through its 80% owned subsidiary, IMG, formed IBC with Beckman
Coulter for the purpose of developing targeted cancer therapeutics.  On March 5,
1999, the Company  contributed  to IBC, on behalf of IMG,  certain rights to its
proprietary  humanized  antibodies  against the cancer  marker  carcinoembryonic

                                       6


     antigen (which had a financial  reporting carrying value of zero), which is
used in its CEA-Cide therapeutic, and Beckman Coulter contributed to IBC certain
rights to its bispecific targeting  technology called the "Affinity  Enhancement
System" or AES.  The  Company  assigned  its rights  pursuant  to the terms of a
license  agreement with IBC dated March 5, 1999 in exchange for the grant to IMG
of its  interest in IBC  ("Immunomedics  License  Agreement").  Beckman  Coulter
received  its  interest in IBC in  exchange  for its  contribution.  The license
granted to IBC is a worldwide,  royalty free,  exclusive license that is limited
to the "IBC Field" with respect to the  "Immunomedics  Patent  Property" and the
"Immunomedics   Biotechnology  Assets,"  as  those  terms  are  defined  in  the
Immunomedics  License  Agreement.   Additionally,  on  March  5,  1999,  several
investors  contributed  $3,000,000  to IBC in exchange  for a 7% interest in the
venture.  IMG's and  Beckman  Coulter's  interests  in IBC are 49.55% and 43.45%
respectively.  Subsequent  capital  contributions  by  individual  investors  in
December  1999 and June 2000 total  $328,000,  but have a  negligible  effect on
ownership  interest.  Beckman  Coulter,  IMG and the  investors  entered into an
operating agreement (the "IBC Operating  Agreement") that establishes the rights
and obligations of the respective members.  Under the terms of the IBC Operating
Agreement,  neither IMG nor Beckman Coulter may sell any portion of its interest
in IBC without  first  providing  the other with a right of first  refusal  with
respect to such sale,  provided that after a public  offering of IBC securities,
IMG and Beckman Coulter will be permitted to sell up to 20% of their  respective
interests in IBC free of such right of first refusal.  IMG is a Delaware limited
liability company owned 80% by the Company and 20% by Dr. David Goldenberg.  Dr.
Goldenberg  received  his  interest  pursuant  to the  terms  of his  employment
agreement with the Company.  IMG is intended to be a single purpose entity,  its
sole asset being its interest in IBC. Dr.  Goldenberg  and IMG have entered into
an operating agreement that establishes their relative rights and obligations.

Relationship with The Center for Molecular Medicine and Immunology

     The Company's product development has involved, to varying degrees, CMMI, a
not-for-profit  specialized  cancer  research  center,  for the  performance  of
certain basic research and  pre-clinical  evaluations,  the results of which are
made available to the Company  pursuant to a collaborative  research and license
agreement.  CMMI is funded  primarily by grants from the NCI. CMMI is located in
Belleville,  New Jersey.  Dr. David M. Goldenberg,  Chairman of the Board 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 Dr. Hans Hansen,  an officer of the Company,  is an adjunct member 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").

     Under the terms of its  license  agreement  with CMMI,  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 license  agreement  terminates  on January 21,  2002,  with the
Company having the right to seek good-faith  negotiation to extend the agreement
for an additional  five-year  period.  Pursuant to a collaborative  research and
license  agreement,  dated as of January 21, 1997, between the Company and CMMI,
the  Company  has paid CMMI an annual  license  fee of  $200,000  in each of the
fiscal years 2001, 2000 and 1999.

     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  $155,000,  $128,000 and $45,000 during the years ended

                                       7


June 30, 2001,  2000 and 1999,  respectively.  The Company also provides,  at no
cost to CMMI,  laboratory  materials and supplies.  However, any inventions made
independently of Immunomedics at CMMI are the property of CMMI.

     During each of the fiscal  years 2001 and 1999,  the Board of  Directors of
the  Company  authorized  grants to CMMI of  $200,000  to support  research  and
pre-clinical  work being  performed  at CMMI,  such  grants to be  expended in a
manner deemed appropriate by the Board of Trustees of CMMI.

Marketing, Sales and Distribution

     In April,  1997, the Company launched  LeukoScan in Europe.  All marketing,
selling  and  distribution  rights  to the  product  have been  retained  by the
Company.   Currently,   Eli  Lilly  Deutschland  GmbH  ("Lilly")   packages  and
distributes  LeukoScan and CEA-Scan within the countries comprising the European
Union and certain other countries subject to the receipt of regulatory  approval
pursuant to a Distribution  Agreement  with the Company.  Lilly has notified the
Company that it intends to terminate this agreement as of the end of the current
calendar  year.  The  Company  expects  to  establish   alternate   distribution
arrangements by that time, although no assurance can be given in this regard.

     The Company has established sales representation  and/or local distributors
in major markets. The Company's European operations are located in Hillegom, The
Netherlands.

     The Company has entered into an agreement with Integrated Commercialization
Solutions, Inc. ("ICS"), a subsidiary of AmeriSourceBergen Corporation (formerly
Bergen  Brunswick).  Under the agreement,  ICS serves as an agent of the Company
providing  product support  services for CEA-Scan in the United States including
customer service, order management, distribution, invoicing and collection.

     On September  9, 1998,  the Company  entered into an agreement  with Syncor
International,  the world's leading  provider of radiopharmacy  services,  under
which Syncor will make CEA-Scan  available to its hospitals and clinic  accounts
throughout  the U.S.,  supported by the Company's  sales and  technical  support
specialists.  Syncor is supporting  the  Company's  efforts with its own team of
field  specialists as well as the licensed  radiopharmacists  who manage its 118
U.S. facilities.

     On February  29,  2000,  the  Company  signed a Letter  Agreement  with KOL
Bio-Medical  Instruments,  Inc.("KOL"),  granting KOL exclusive rights to market
and sell CEA-Scan in the northeastern  U.S. This agreement was terminated by the
Company on April 19, 2001.

Manufacturing

     To date, the Company has  manufactured all  investigational  agents 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 is planning to expand the manufacturing facility and
its  capacity  with  additional   bioreactors  for  antibody  production.   This
additional  capacity is intended to support the production of new antibody-based
therapeutics as well as increase the production volumes of existing products.

     The  Company  has  entered   into  a   manufacturing   agreement   with  SP
Pharmaceuticals,  LLC,  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.

                                       8


     The Company's Morris Plains  headquarters also houses regulatory,  medical,
research  and  development,   finance,  marketing  and  executive  offices  (see
"Properties").  The Company has scaled-up to commercial  levels its  down-stream
antibody  purification  and  fragmentation   manufacturing   processes  for  its
diagnostic  imaging  products.  The  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 facility
were  completed  in  December,  1998.  The  manufacturing  facility  and product
manufacturing  processes were approved by the Committee on Proprietary Medicinal
Products  ("CPMP") of the European  Commission  in May,  1998.  The facility and
processes were approved by the FDA for CEA-Scan in December, 1998.

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 products,  currently  consisting of 70 issued
United States patents (3 of the Company's earliest patents have now expired) and
219 issued foreign patents,  with 43 United States patent applications  pending,
of which 1 has been allowed,  and 126 foreign patent  applications  pending,  of
which 22 have  been  allowed.  Included  in the  foregoing  are 4 United  States
patents and 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.

     During  the 2001  fiscal  year,  10 United  States  patents  and 21 foreign
patents (4 in Australia,  4 in Canada,  1 from the European  Patent Office which
was validated in Italy,  France,  Germany and Great Britain,  1 in Ireland, 1 in
Israel, 1 in Japan and 2 in Singapore) were issued to the Company.

     The Company's  patents contain claims directed to, among other things,  its
current in vivo cancer  imaging  products and its methods of producing  them, as
well as the compositions of many of its  antibody-based  therapeutic  agents and
its  method of  treatment  for  various  cancers.  Since  some of the  Company's
patented technologies are platform  technologies,  the Company has also patented
applications  outside  of  cancer,  such  as the  treatment  of  autoimmune  and
infectious  diseases.  In addition,  the Company has patented  technologies  and
products comprising potential vaccines for cancer and infectious diseases.

     In July,  2000, two United States patents issued,  the first with claims to
RNase conjugates for disease  therapy,  the second with claims to stimulating an
immune response with antibodies labeled with the alpha-glactosyl epitope.

     In  August,   2000  a  United   States   patent   issued   with  claims  to
intraoperative,  intravascular and endoscopic tumor and lesion detection, biopsy
and therapy using radiolabeled antibody fragments.

     In September,  2000, the Company  received a United States patent  claiming
DOTA-biotin derivatives.

     In October,  2000, two United States patents issued,  the first with claims
to  radiometal-binding  peptide  analogues  , the second  claiming a  multistage
cascade-boosting vaccine.

     In February,  2001, the Company  received two United States patents one for
humanized  and  chimerized  forms  of  its  CD22  antibody  (epratuzumab)  being
developed as a treatment for non-Hodgkin's  lymphoma (NHL), and one covering any
CD22  antibody  used  alone or in a  combination  therapy  for  NHL.  One of the

                                       9


Australian  patents  awarded to the Company  included  similar  claims.  A third
United  States  patent  issued in February  covering  methods  for  fluorinating
proteins and peptides for F-18 positron emission tomography.

     Finally,  in May,  2001, a United States patent issued with claims to boron
neutron capture therapy using pre-targeting methods.

     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.  Five of the licensed  United States patents have now expired.  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  Annual  Net
Revenue (as  defined) 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 interests
therein (other than Undeveloped  Assets (as defined)),  including  Royalties (as
defined),  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  three  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 Prior Inventions (as defined) 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 three years)
of any Undeveloped  Assets (as defined) of the Company which are not budgeted as
part of the Company's strategic plan. Pursuant thereto,  Dr. Goldenberg received
a 20% interest in IBC Pharmaceuticals, LLC (see "Introduction").

     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

                                       10


material  contribution  to  the  invention  or  development  of  such  products,
technologies or businesses prior to the time of acquisition.  Except as affected
by a Change in Control (as  defined)  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 three 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.

     The  Company has  extended  Dr.  Goldenberg's  employment  agreement  for a
five-year period,  expiring on June 30, 2006. Further,  the Company acknowledged
and  approved  Dr.  Goldenberg's   continuing  involvement  with  CMMI  and  IBC
Pharmaceuticals, LLC.

     Pursuant to a License  Agreement  dated July 7, 1983,  the  Company  paid a
royalty 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.  Under the agreement,  a final payment was made to Dr. Primus in
June 2000.

     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  that 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 brought suit in The Netherlands  against F.
Hoffmann-LaRoche  and its Roche Diagnostics  subsidiary and European  affiliates
for  infringement of the Company's  European patent covering  specific  anti-CEA
antibodies,  which  Roche is using in its CEA  immunoassay.  The suit  sought an
injunction  against  the sale of CEA  immunoassays  by Roche that  infringe  the
Company's  European  patents,  as well as damages for past  infringement.  Roche
denied  infringement  and countered with nullity  actions in The Netherlands and
Germany,  seeking to invalidate the Company's Dutch and German patents.  A trial
was held before the Patent  Court in The Hague on August 8, 1997,  resulting  in
dismissal of the action. The Company has appealed.  A trial on the Dutch nullity
action was held before the Patent Court in The Hague on June 5, 1998,  resulting
in  dismissal  of that  action and  maintenance  of all claims of the  Company's
patent.  Roche has appealed.  A trial on the German  nullity  action was held in
Munich on December 9, 1998,  resulting in  maintenance  of the patent in amended
form that  continues  to protect the  Company's  products and which the Company
believes is still infringed by Roche's  immunoassays.  Roche did not appeal. The
appeals of the Dutch infringement and nullity actions were heard concurrently on
March 2, 2000. A decision,  although  originally  set for September 7, 2000, was
rendered on February 15, 2001, and then only a partial decision. The validity of
the patent,  with claims amended as they were in the German  action,  was upheld
and the  jurisdiction of the Dutch Court to issue a cross-border  injunction was
upheld. The Dutch Appeals Court did not reach a decision on infringement and has
now solicited  additional  submissions from each side, which have been provided,
and suggested  that an expert be designated to advise the Court on the technical

                                       11


issues. Moreover, Roche has appealed the remaining holdings of the Appeals Court
to the Dutch Supreme  Court.  Each side has  submitted  pleadings to the Supreme
Court in this appeal. The Company's patent counsel believes that the patents are
valid and infringed,  and that an unfavorable  outcome is unlikely,  although no
assurances  can be given in this  regard.  To the extent that Roche  contests or
challenges the Company's  patents,  or files appeals or further nullity actions,
there can be no assurance that significant  costs for defending such patents may
not be incurred.

     In July, 1998, a license  agreement was signed between the Company and Dako
A/B under the  Company's  worldwide  patents for  specific  anti-CEA  monoclonal
antibodies,  which  Dako  markets  for in vitro use.  The  Company is engaged in
active  discussions  with  other  companies  that  may  be  using  its  patented
technology without the Company's approval in current products or products now in
development or clinical testing.

     The  Company  has  also  sued  Cytogen,   Inc.  and  C.R.  Bard,  Inc.  for
infringement  of  the  Company's  licensed  patent  by  Cytogen's  sale  of  its
"Prostascint"  prostate cancer imaging  product.  The complaint was filed in New
Jersey on February 23, 2000 and served on March 20, 2000, after two unsuccessful
attempts at  settlement.  The suit was  bifurcated  and damages were  separated.
Discovery was completed on the liability  issues.  Although the Company believes
that its patent is valid and  infringed,  there can be no assurance that a judge
will interpret the claims properly or that a jury will find infringement or that
the Company  will not incur  significant  costs in pursuing  the suit  despite a
negotiated fee arrangement with its patent counsel.

     The mark  "IMMUNOMEDICS"  is registered in the United States and 19 foreign
countries and a European  Community  Trademark  has been granted.  The Company's
logo also is  registered in the United  States and in 2 foreign  countries.  The
mark  "IMMUSTRIP"  is  registered  in the  United  States and  Canada.  The mark
"CEA-SCAN" is registered  in the United  States and 7 foreign  countries,  and a
European  Community  Trademark  has  been  granted.   The  mark  "LEUKOSCAN"  is
registered  in the  United  States  and 10  foreign  countries,  and a  European
Community Trademark has been granted. The mark "LYMPHOSCAN" is registered in the
United States and 8 foreign countries,  and a European  Community  Trademark has
been granted.  The mark  "CEA-CIDE" is  registered in the United  States,  and a
European  Community  Trademark  has  been  granted.  The  mark  "LYMPHOCIDE"  is
registered in the United  States,  and a European  Community  Trademark has been
granted.  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.

                                       12


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

     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.

     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,  CEA-Scan for the diagnosis of medullary thyroid cancer
and CEA-Cide for therapy of  pancreatic,  ovarian and lung cancers.  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.

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 better equipped than the Company
to develop,  refine and market  products  based on  technologies  applied to the

                                       13


diagnosis and treatment of cancers and infectious diseases.  The Company expects
to face increasing  competition from universities and other non-profit  research
institutions.  These institutions carry out a significant amount of research and
antibody-based  technology,  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'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.

     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  24, 2001,  the Company  employed 85 persons on a full-time
basis,  19 of whom are in research and development  departments,  13 of whom are
engaged in clinical research and regulatory  affairs,  27 of whom are engaged in
operations and manufacturing and quality control,  and 26 of whom are engaged in
finance, administration,  sales and marketing. Of these employees, 29 hold M.D.,
Ph.D.  or  other  advanced  degrees.  The  Company  believes  that  it has  been
successful in attracting skilled and experienced scientific personnel;  however,
competition for such personnel continues to be intense.  The Company's employees
are not covered by a collective bargaining  agreement,  and the Company believes
that its relationship with its employees is excellent.

Business Risks

     For a description of certain risks  affecting the Company's  business,  see
Exhibit 99.1 annexed to this Annual Report on Form 10-K.

Item 2 -- Properties

     The Company's  headquarters is located at 300 American Road, Morris Plains,
New Jersey,  where it leases  approximately 74,000 square feet. On May 29, 1998,
the Company  exercised  its right to renew the lease for an  additional  term of
three years expiring in May 2002, at a base annual rental of $441,000. In August
2001, the Company renewed for an additional term of twenty years expiring in May
2022 at a base annual rate of $545,000,  which is fixed for the first five years
and increases  thereafter every five years,  which includes an additional 15,000
square feet. (See "Management's  Discussion and Analysis of Financial  Condition
and Results of  Operations - Liquidity  and Capital  Resources.")  The Company's
manufacturing,  regulatory,  medical,  research  and  development  laboratories,
finance, marketing and executive offices are currently located in this facility.
The  Company  has also  completed  the  construction  and  equipping  of a 7,500

                                       14


square-foot  commercial-scale  manufacturing  facility  within the 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

     The  Company is a party to 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.

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 2001.

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

Overview

     Statements  made in this  Annual  Report on Form  10-K,  other  than  those
concerning  historical  information,  should be considered  forward-looking  and
subject to various risks and  uncertainties.  These  forward-looking  statements
include,  but  are  not  limited  to,  statements  about  the  Company's  plans,
objectives,  expectations and intentions and other statements  contained in this
Annual Report on Form 10-K or elsewhere that are not historical facts. When used
in  this  Annual  Report  on  Form  10-K  or  elsewhere,  the  words  "expects,"
"anticipates,"  "intends,"  "plans,"  "believes,"  "seeks" and  "estimates"  and
similar   expressions  are  generally   intended  to  identify   forward-looking
statements.  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. In evaluating such  forward-looking  statements,
stockholders  and  potential   investors  should   specifically   consider,   in
conjunction  with  the  Company's  financial  statements,  the  various  factors
described in Exhibit 99.1 annexed hereto and risk factors described elsewhere in
this Annual Report on Form 10-K.  These  factors may cause the Company's  actual
results to differ materially from the results indicated by these forward-looking
statements.

     The  Company  is  committed  to  developing,  manufacturing  and  marketing
monoclonal  antibody-based  products for the  detection and treatment of cancers
and other diseases. The Company's major focus is therapeutic antibodies that are
designed to carry radioisotopes,  chemotherapeutic agents, toxins, dyes or other
substances to a specific  target,  such as a disease site or organ  system,  and
bind to the  target.  The  Company  has  several  such  antibodies  in  clinical
development,  including  epratuzumab,  which  is in  Phase  III  trials  for the
treatment  of patients  with  non-Hodgkin's  lymphoma.  This  antibody  has been
licensed to Amgen, Inc., for further development and  commercialization in North
America and Australia.  The Company has two commercial diagnostic imaging agents
which utilize the Company's monoclonal antibodies,  CEA-Scan and LeukoScan, that
are being sold for the  detection  of  colorectal  cancers and bone  infections,
respectively. These are the only products that the Company is currently licensed
to market and sell and to date,  the Company has received only limited  revenues
from the sale of these  products.  The  Company  is also  developing  new cancer
therapeutic  antibody technology involving the selective delivery of therapeutic
agents through pre-targeting, in collaboration with IBC.

     From  inception in 1982 until June 30, 2001, the Company had an accumulated
deficit of approximately $114,000,000 and has never earned a profit. The Company
obtains limited revenues from the sales of its approved  products,  CEA-Scan and
LeukoScan.  These  revenues  may not  increase  and the Company may be unable to
commercialize  additional products. In the absence of increased revenue from the
sale of current or future  products (the amount,  timing,  nature,  or source of
which cannot be  predicted),  the Company's  losses will continue as it conducts
its research and development  activities.  These activities may expand over time
and require further resources,  and the Company's operating losses are likely to
be substantial over the next several years.

Results of Operations

Fiscal Year 2001 compared to Fiscal Year 2000

     Revenues  for the fiscal  year ended June 30,  2001,  were  $11,229,000  as
compared to $5,973,000 in the fiscal year ended June 30, 2000,  representing  an
increase  of  $5,256,000  or 88%.  Product  sales  for  fiscal  year  2001  were
$4,032,000, as compared to $4,124,000 in fiscal year 2000, representing a

                                       18


decrease of $92,000,  principally  reflecting the Company's  transition in focus
from  development of in vivo imaging  products to the development of therapeutic
compounds.  Royalties and license fee revenue for fiscal year 2001  increased by
$3,744,000 from $14,000 to $3,758,000 as compared to fiscal 2000,  primarily due
to recognition of $3,750,000 of the  $18,000,000  up-front  payment  received in
conjunction  with  the  execution  of  the  Company's  development  and  license
agreement with Amgen.  The up-front  payment is being recognized as revenue at a
rate of  $750,000  per month over an  estimated  period of 24 months,  beginning
February 2001.  Revenue from grants for research and development for fiscal year
2001  decreased by $29,000 from $639,000 to $610,000 as compared to fiscal 2000,
primarily  due to a lower rate of funding for grants.  Interest and other income
for fiscal year 2001 increased by $1,633,000  primarily due to increased  levels
of cash available for investment as a result of the sale of unregistered  shares
of common stock during  fiscal 2000 and the receipt of the  $18,000,000  payment
from Amgen in February 2001.

     Total operating  expenses for fiscal year 2001 were $16,783,000 as compared
to  $15,609,000 in fiscal year 2000,  representing  an increase of $1,174,000 or
8%. Research and development  expenses increased by $1,594,000,  from $8,670,000
to  $10,264,000  as  compared to fiscal year 2000,  primarily  due to  increased
research and  development  efforts and  manufacturing  expenses,  including  lab
supplies associated with producing  therapeutic compounds to be used in clinical
trials.  Cost of goods sold for fiscal year 2001  increased  by  $462,000,  from
$429,000 to  $891,000  as compared to fiscal year 2000.  Cost of goods in fiscal
year 2000  reflects  the  benefit  of  product  sales  from  inventory  that was
previously  expensed by the Company prior to receiving product  approval.  Also,
the cost of goods  sold in  fiscal  years  2001 and 2000  includes  a charge  of
approximately $105,000 and $155,000, respectively, relating to the expiration of
vials of CEA-Scan previously  manufactured and capitalized.  Sales and marketing
expenses  for fiscal year 2001 were  $2,502,000  as compared to  $2,896,000  for
fiscal year 2000,  representing a decrease of $394,000, or 14%, primarily due to
the Company-wide  reorganization/restructuring  as the Company refocused efforts
on the development of therapeutic  compounds.  General and administrative  costs
for fiscal year 2001  decreased by $488,000  from  $3,614,000  to  $3,126,000 as
compared to fiscal year 2000.  The Company  recognized an expense of $509,000 in
fiscal 2001,  as compared to $925,000 in fiscal 2000,  associated  with warrants
issued to a financial advisor (see Note 7 to Consolidated Financial Statements).
Also, in fiscal 2001, bonuses awarded to executives were $266,000 as compared to
$880,000 in fiscal year 2000.  In addition,  the Company  recognized a charge of
$360,000 during fiscal year 2001 as a fee associated with the Company's entering
into  the  Licensing  and  Development  Agreement  with  Amgen  (see  Note 10 to
Consolidated Financial Statements).

     During  fiscal 2001,  the Company  sold  approximately  $10,106,000  of New
Jersey state net operating losses, pursuant to a program offered by the State of
New  Jersey.  The Company  recorded an income tax benefit of $803,000  resulting
from that transaction.

     Net  loss  allocable  to  common  shareholders  for  fiscal  year  2001 was
$4,751,000, or $0.10 per common share, as compared to $10,132,000,  or $0.23 per
common  share,  in fiscal  year  2000.  The lower net loss  allocable  to common
shareholders of $5,381,000 in 2001 as compared to fiscal year 2000 was primarily
due to the Company's  increased revenues  principally  related to the recognized
portion of the Amgen up-front  payment and interest earned on  investments,  the
income tax  benefit  of  $803,315  related  to the sale of New Jersey  state net
operating  losses during fiscal year 2001,  and the fact that no dividends  were
owed on preferred stock during the fiscal year 2001.  This was partially  offset
by higher operating  expenses primarily in the area of research and development.
In addition,  the net loss allocable to common shareholders per share for fiscal
2001 was  positively  impacted by the higher  weighted  average number of shares
outstanding  during such period as compared to fiscal 2000.  The increase in the
weighted average number of shares  outstanding from 43,976,658 to 49,498,002 was
primarily due to the conversion in late calendar year 1999 of the Company's

                                       19


Series F Preferred Stock into 5,772,031  shares of common stock and the issuance
of 4,825,000 shares of common stock pursuant to the Company's equity  financings
during fiscal year 2000, as these shares were  outstanding for the entire fiscal
year 2001 (see Note 7 to Consolidated Financial Statements).

Fiscal Year 2000 compared to Fiscal Year 1999

     Revenues  for the  fiscal  year  ended  June 30,  2000 were  $5,973,000  as
compared to  $7,559,000 in the fiscal year ended June 30, 1999,  representing  a
decrease  of  $1,586,000  or 21%.  Product  sales for the fiscal  year 2000 were
$4,124,000  as  compared  to  $6,097,000  in fiscal  year 1999,  representing  a
decrease of $1,973,000. This was primarily due to the reorganization of the U.S.
and European sales forces, which occurred in April 1999. Revenue from grants for
research and development for fiscal year 2000 decreased by $48,000 from $687,000
to $639,000 as compared to fiscal 1999, primarily due to a lower rate of funding
for grants. Interest and other income for fiscal year 2000 increased by $438,000
from  $758,000 to  $1,196,000  as compared  with fiscal  1999.  Interest  income
increased by $767,000 due to increased  levels of cash  available for investment
as a result of the sale of  unregistered  shares of common stock  during  fiscal
2000.  Other  income  decreased  by  $328,000  primarily  due to the  receipt of
$300,000 in December 1998, in final settlement of all claims between the Company
and  Mallinckrodt,  Inc. and its  affiliate  under  certain  prior  distribution
agreements, which were terminated in April 1998.

     Total operating  expenses for fiscal year 2000 were $15,609,000 as compared
to  $18,838,000 in fiscal year 1999,  representing a decrease of $3,229,000,  or
17%.  Research and development costs decreased by $1,430,000 from $10,100,000 to
$8,670,000  as  compared  to fiscal year 1999,  primarily  due to the  Company's
restructuring  efforts in fiscal 1999 and lower costs  associated  with  reduced
patient enrollment for clinical trials.  Cost of goods sold for fiscal year 2000
increased by $49,000 from  $379,000 to $428,000 as compared to fiscal year 1999.
Included  in the  cost of  goods  sold  for  fiscal  year  2000 is a  charge  of
approximately  $155,000  due to  expiration  of  vials  of  CEA-Scan  previously
manufactured  and  capitalized  which  was  partially  offset  by the  effect of
decreased  product  revenues.  In addition,  cost of goods sold for fiscal years
2000 and 1999 were favorably  impacted  because they did not include  production
costs of certain products sold because such costs were previously expensed prior
to receiving the required regulatory approvals. Sales and marketing expenses for
fiscal year 2000 were  $2,896,000 as compared to $6,422,000 in fiscal year 1999,
representing  a decrease of $3,526,000 or 55% primarily due to the  Company-wide
reorganization/restructuring.  General and administrative  costs for fiscal year
2000  increased by $1,679,000 as compared to fiscal year 1999,  primarily due to
the  recognition of an expense of $925,000  associated with warrants issued to a
financial advisor in December 1999 and $880,000 awarded to executives as a bonus
in fiscal year 2000 (see Note 7 to Consolidated Financial Statements).

     Net  loss  allocable  to  common  shareholders  for  fiscal  year  2000 was
$10,132,000, or $0.23 per common share, as compared to $11,688,000, or $0.31 per
common share,  in fiscal year 1999.  The lower net loss  allocable to the common
shareholders of $1,556,000 in 2000 as compared to fiscal year 1999 was primarily
due to  lower  operating  expenses,  partially  offset  by  lower  revenues,  as
discussed above. In addition,  the net loss allocable to common shareholders per
share for fiscal 2000 was  positively  impacted by the higher  weighted  average
number of shares  outstanding during such period as compared to fiscal 1999. The
increase in the weighted average number of shares outstanding from 37,782,376 to
43,976,658  was  primarily  due to the  conversion  of the  Company's  Series  F
Preferred  Stock  into  302,003  shares of  common  stock  and the  issuance  of
4,825,000  shares of common stock  pursuant to the Company's  equity  financings
during fiscal year 2000. (see Note 7 to Consolidated Financial Statements).

Liquidity and Capital Resources

     Since inception, in 1982, the Company has financed its operations primarily
through  private  placements  of its equity  securities,  revenue  earned  under
licensing agreements,  revenue from sales of CEA-Scan and LeukoScan, grants from
various sources, and investment income.

     At  June  30,  2001,  the  Company  had  working  capital  of  $43,202,000,
representing  an increase of $3,049,000  from  $40,153,000  in June 30, 2000. At
June 30, 2001,  the Company had no long-term debt or capital  lease  obligations
(see Notes 11 and 12 of Notes to  Consolidated  Financial  Statements).  The net
increase in working capital  resulted  principally  from the up-front payment of
$18,000,000  received from the Amgen agreement  partially offset by the net loss
allocable to common shareholders during fiscal year 2001 of $4,751,000,  capital
expenditures  and the recording of a portion of the up-front payment as deferred
revenue as of June 30, 2001.

     On October  28,  1998,  the Company  entered  into an  Equipment  Financing
Agreement  with the New  England  Capital  Corporation,  pursuant  to which  the
Company has received $450,000, to be repaid over a 36-month period. The proceeds
of such financing were used to exercise the early purchase options for equipment
previously  leased through a master lease agreement.  At June 30, 2001,  $70,000
was  outstanding  which is payable in  monthly  installments  over the next five
months.  The financing is secured by various used  equipment and an  irrevocable
letter  of  credit  in  the  amount  of  $225,000.   The  letter  of  credit  is
collateralized by a cash deposit of an equivalent amount.

     The Company's cash, cash equivalents and marketable  securities amounted to
$53,291,000  at June 30,  2001,  representing  an increase of  $12,425,000  from
$40,866,000 at June 30, 2000.  This increase was primarily  attributable  to the
up-front  payment of $18,000,000  received from the Amgen  agreement,  partially
offset by the funding of  operating  expenses.  It is  anticipated  that working
capital and cash,  cash  equivalents,  and marketable  securities  will decrease
during  fiscal year 2002 as a result of planned  operating  expenses and capital
expenditures,  offset in part by projected  revenues from sales of the Company's
imaging products in the U. S. and Europe.  However, there can be no assurance as
to the amount of revenues, if any, these imaging products will provide.

     To date, the Company has not generated  positive cash flow from operations,
excluding the effects of the up-front payment received from Amgen in fiscal year
2001.  The  Company  believes  that  its  existing  working  capital  should  be
sufficient  to meet its capital and liquidity  requirements  for the next twelve
months. Actual results could differ materially from the Company's expectation as
a result of a number of risks and  uncertainties,  including the risks described
in Exhibit  99.1  annexed  hereto.  The  Company's  working  capital and working
capital  requirements are affected by numerous factors and such factors may have
a negative  impact on the  Company's  liquidity.  Principal  among these are the
success of product  commercialization and marketing products,  the technological
advantages and pricing of the Company's  products,  the impact of the regulatory
requirements  applicable  to the Company and access to capital  markets that can
provide the Company with the  resources  when  necessary  to fund its  strategic
priorities.  Unless there is a  significant  increase in product  revenues,  the
Company  will  require  additional  financial  resources  after it utilizes  its
current  liquid  assets  in order for it to  continue  its  projected  levels of
research  and  development,  clinical  trials  of  its  potential  products  and
regulatory  filings  for  new  indications  of  existing  products.   Additional
financing  may not be  available  to the  Company  at all or on  terms  it finds
acceptable  or the terms of such  financing  may cause  substantial  dilution to
existing stockholders.

     The Company intends to supplement its financial resources from time to time
as market  conditions  permit through  additional debt or equity  financings and
through  collaborative  marketing  and  distribution  agreements.   The  Company

                                       21


continues to evaluate various  programs to raise additional  capital and to seek
additional revenues from the licensing of its proprietary  technologies.  At the
present  time,  the Company is unable to  determine  whether any of these future
activities will be successful and, if so, the terms and timing of any definitive
agreements.

Recently Issued Accounting Pronouncements

     In July 2001, the FASB issued SFAS No. 141, Business Combinations, and SFAS
No. 142,  Goodwill  and Other  Intangible  Assets.  SFAS 141  requires  that all
business  combinations  be accounted  for under a single  method -- the purchase
method. Use of the pooling-of-interests  method no longer is permitted. SFAS 141
requires that the purchase  method be used for business  combinations  initiated
after June 30, 2001.  SFAS 142 requires  that goodwill no longer be amortized to
earnings, but instead be reviewed for impairment.  SFAS No. 142 has no impact on
the historical  financial statements of the Company as the Company does not have
any goodwill or intangible assets which resulted from business combinations.

Item 7A -- Quantitative and Qualitative Disclosures About Market Risk

     The following  discussion  about the  Company's  exposure to market risk of
financial  instruments  contains  forward-looking  statements  under the Private
Securities  Litigation  Reform Act of 1995. Actual results may differ materially
from  those  described  due to a  number  of  factors,  including  uncertainties
associated  with  general  economic  conditions  and  conditions  impacting  the
Company's industry.

     The Company's holdings of financial  instruments are comprised primarily of
corporate debt. All such instruments are classified as securities  available for
sale. The Company does not invest in portfolio equity  securities or commodities
or use financial  derivatives for trading purposes.  The Company's debt security
portfolio  represents  funds held  temporarily  pending use in its  business and
operations.  The Company  manages  these funds  accordingly.  The Company  seeks
reasonable  assuredness  of the  safety of  principal  and market  liquidity  by
investing  in rated fixed  income  securities  while at the same time seeking to
achieve a favorable rate or return.  The Company's market risk exposure consists
principally  of exposure to changes in interest  rates.  The Company's  holdings
also are exposed to the risks of changes in the credit  quality of issuers.  The
Company  typically invests in highly liquid debt instruments with fixed interest
rates.

interest  rates by fiscal year of maturity  for our  investment  portfolio as of

                       Immunomedics, Inc. and subsidiaries
                   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 currently markets and sells CEA-Scan(R)in the U.S., and CEA-Scan and
LeukoScan(R)throughout Europe and in certain other markets outside the U.S.

     The Company's operations encompass all the risks inherent in developing and
expanding a biopharmaceutical  enterprise,  including: (1) 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  substantial  competition,
rapid technological change and strict government regulation.

The Company has not yet achieved profitable operations and there is no assurance
that  profitable  operations,  if  achieved,  could be sustained on a continuing
basis.  Further,  the Company's future  operations are dependent on, among other
things,  the  success  of the  Company's  commercialization  efforts  and market
acceptance of the Company's products. Since its inception in 1982, the Company's
source of funds has been primarily  dependent on private and public offerings of
equity securities, revenues from research and development alliances, and product
sales.

2.     Summary of Significant Accounting Policies

Principles of Consolidation and Presentation

     The consolidated financial statements include the accounts of Immunomedics,
Inc. and its majority-owned subsidiaries.  All significant intercompany balances
and transactions  have been eliminated in  consolidation.  Minority  interest is
recorded for a  majority-owned  subsidiary  (see Note 10).  Certain amounts have
been reclassified to conform to the current year presentation.

Cash Equivalents and Marketable Securities

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

     The Company's investments in cash equivalents and marketable securities are
available for sale to fund growth in operations.  The portfolio at June 30, 2001
primarily consists of corporate debt securities.

Concentration of Credit Risk

     Cash, cash equivalents, and marketable securities are financial instruments
that  potentially  subject  the Company to  concentration  of credit  risk.  The
Company  invests its cash in 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.  The Company has  historically
held the investments to maturity. However, the

                                       27


                       Immunomedics, Inc. and subsidiaries
            Notes to Consolidated Financial Statements - (Continued)

Company  has the  ability  to sell these  investments  before  maturity  and has
therefore  classified the investments as available for sale. The Company has not
experienced any significant losses on its investments.

Inventory

     Inventory  is stated  at the  lower of  average  cost  (which  approximates
first-in,  first-out) or market, and includes materials, labor and manufacturing
overhead.

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. Leasehold improvements are capitalized and amortized over the
lesser of the life of the lease or the estimated  useful life of the asset.  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.  Statement of
Financial  Accounting  Standards ("SFAS") No. 121, Accounting for the Impairment
of Long-Lived  Assets and for Long-Lived  Assets to be Disposed of has not had a
material  impact on the Company's  consolidated  financial  position,  operating
results or cash flows.

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.
Upfront  nonrefundable  fees associated with license and development  agreements
where the Company has continuing  involvement in the agreement,  are recorded as
deferred  revenue and  recognized  over the  estimated  service  period.  If the
estimated  service period is  subsequently  modified,  the period over which the
upfront  fee is  recognized  is modified  accordingly  on a  prospective  basis.
Revenues  from the  achievement  of  research  and  development  milestones  are
recognized when the milestones are achieved.

     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  consolidated
financial statements and tax returns. During fiscal 2001, the Company

                                       28


                       Immunomedics, Inc. and subsidiaries
            Notes to Consolidated Financial Statements - (Continued)

recognized a tax benefit as a result of the sale of New Jersey net operating
loss carryforwards (see Note 8).

Net Loss Per Share

     Net loss per basic and  diluted  common  share is based on the net loss for
the relevant  period,  adjusted for Preferred  Stock  dividends,  divided by the
weighted  average  number of common  shares  issued and  outstanding  during the
period.  Preferred  Stock  dividends for the fiscal year 2000 included  $199,184
related to a 4% per annum  stated  value  increase  in  security  and a $297,500
premium paid in December 1999 in connection  with the redemption of the Series F
Preferred  Stock.  Preferred  Stock  dividends  for  fiscal  year 1999  included
$281,944  related to a 4% per annum  stated  value  increase in security  and an
assumed  incremental yield  attributable to a beneficial  conversion  feature of
$127,500. No such Preferred Stock dividends were recorded in fiscal year 2001 as
the  related  Preferred  Stock was fully  redeemed  in  December  1999.  For the
purposes of the diluted net loss per common share calculations,  the exercise or
conversion of all potential  common shares is not included  because their effect
would have been anti-dilutive,  due to the net loss recorded for the years ended
June 30, 2001,  2000 and 1999.  The common stock  equivalents  excluded from the
diluted per share  calculation  are  2,456,750,  1,936,000 and 2,611,500 for the
fiscal years ended June 30, 2001, 2000 and 1999, respectively.

Use of Estimates

     The  preparation  of financial  statements  in conformity  with  accounting
principles   generally  accepted  in  the  United  States  of  America  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 the financial  statements  and the reported  amounts of revenues and
expenses  during the reported  period.  Actual  results  could differ from those
estimates.

Comprehensive Loss

     Comprehensive  loss consists of net loss, net unrealized  gains (losses) on
securities  available  for sale and  certain  foreign  exchange  changes  and is
presented in the consolidated statements of operations and comprehensive loss.

Employee Stock Options

     The  Company  applies  the  intrinsic   value-based  method  of  accounting
prescribed by Accounting Principles Board ("APB") Opinion No. 25, Accounting for
Stock Issued to Employees,  and related  interpretations,  in accounting for its
fixed plan stock options. As such, compensation expense would be recorded on the
date of grant only if the then  current  market  price of the  underlying  stock
exceeded  the  exercise  price.   SFAS  No.  123,   Accounting  for  Stock-Based
Compensation,  established  accounting and disclosure  requirements using a fair
value-based method of accounting for stock-based employee compensation plans. As
allowed by SFAS No.  123,  the  Company  has  elected to  continue  to apply the
intrinsic  value-based method of accounting described above, and has adopted the
disclosure requirements of SFAS No. 123.

     When the exercise  price of employee or director stock options is less than
the fair value of

                                       29




                       Immunomedics, Inc. and subsidiaries
            Notes to Consolidated Financial Statements - (Continued)

the underlying stock on the grant date, the Company records compensation expense
for the  difference  over the vesting  period of the  options.  Options or stock
awards issued to non-employees  and consultants are recorded at their fair value
as determined in accordance with SFAS No. 123 and EITF No. 96-18, Accounting for
Equity  Instruments That Are Issued to Other Than Employee for Acquiring,  or in
Conjunction  with  Selling,  Goods or Services and  recognized  over the related
vesting period.

Financial Instruments

     The carrying amounts of cash and cash equivalents, other current assets and
current  liabilities  approximate  fair value due to the short-term  maturity of
these  instruments.  The fair value,  which equals carrying value, of marketable
securities  available for sale is based on quoted market prices.  Long-term debt
rates are consistent with market rates;  thus carrying value  approximates  fair
value.

     In June 1998,  SFAS No. 133,  Accounting  for  Derivative  Instruments  and
Hedging Activities was issued and, as amended, is effective for all fiscal years
beginning  after June 15, 2000.  SFAS No. 133  standardizes  the  accounting for
derivative  instruments  including certain  derivative  instruments  embedded in
other contracts and requires  derivative  instruments to be recognized as assets
and liabilities and recorded at fair value.  The Company  currently is not party
to any  derivative  instruments.  The Company's  adoption of SFAS No. 133 had no
impact  on  the  Company's   consolidated   financial  statements.   Any  future
transactions  involving  derivative  instruments will be evaluated based on SFAS
No. 133.

3.     Marketable Securities

     The Company  utilizes SFAS No. 115,  Accounting for Certain  Investments in
Debt and Equity Securities, to account for investments in marketable securities.
Under this accounting  standard,  securities for which there is not the positive
intent and ability to hold to maturity are classified as available-for-sale  and
are carried at fair value.  Unrealized  holding  gains and losses on  securities
classified  as  available-for-sale  are  carried  as  a  separate  component  of
accumulated other comprehensive  income (loss). The Company considers all of its
current investments to be available-for-sale.  Marketable securities at June 30,
2001 and 2000 consist of the following:




                                                   Gross            Gross          Estimated

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 December 23,  1997,  the Company  entered into a Structured  Equity Line
Flexible  Financing   Agreement  (the  "Equity  Line")  with  an  investor  (the
"Investor"),   pursuant  to  which,  subject  to  the  satisfaction  of  certain
conditions,  the Company could have  received up to an aggregate of  $30,000,000
over a 36-month period. The Company terminated the Equity Line as of December 9,
1998. As of the termination date, the Company had received a total of $5,350,000
for which the Company  issued  1,358,838  shares of common stock.  In connection
with the Equity Line, the Company issued to the Investor a four-year  warrant to
purchase 50,000 shares of common stock at an exercise price of $7.5375 per share
(180% of the closing  sales price of the  Company's  common stock at the time of
issuance).  In  addition,  the  Company  issued to the  Investor  an  additional
four-year warrant to purchase 54,000 shares of common stock  (representing 5,000
shares for each  $500,000 of common stock  purchased  by the Investor  under the
Equity Line during  calendar year 1998).  The exercise price of such  additional
warrant is $7.087 per share (180% of the weighted  average purchase price of the
common  stock  purchased by the Investor  during the year).  These  warrants are
outstanding as of June 30, 2001.

     On December 9, 1998,  the Company  completed a private  placement  of 1,250
shares of Series F Convertible Preferred Stock (the "Series F Stock") to several
investors and received net proceeds of $12,349,800. Each share of Series F Stock
had an initial  stated value of $10,000,  which  increased at the rate of 4% per
annum.  As of  December  16,  1999,  655  shares of the  Series F Stock had been
converted into 5,772,031  shares of common stock in non-cash  transactions.  The
remaining 595 shares of Series F Stock were repurchased,  in accordance with the
terms of the Series F Stock,  by the Company on that date from the then  current
holders at a price  equal to 109% of the  initial  stated  value of $10,000  per
share of Series F Stock.

     On December 16, 1999, the Company issued warrants covering 75,000 shares of
its common  stock at an exercise  price of $6.50 per share.  The  warrants  were
issued  to  induce a  financial  advisor  to  enter  into a  financial  advisory
agreement with the Company.  In accordance with EITF Issue No 96-18,  Accounting
for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or
in Conjunction  with Selling,  Goods or Services and other  relative  accounting
literature,  the Company was required to measure the expense associated with the
warrants at each  reporting  date and recognize the  appropriate  portion of the
expense  at the end of each  reporting  period  until the  measurement  date was
reached  (December  31,  2000 in this  transaction).  As a result,  the  Company
recognized a proportionate  share of the general and  administrative  expense of
approximately  $509,000 and $925,000 during the fiscal years ended June 30, 2001
and 2000, respectively, which represented the estimated value of the warrants as
of that date. These warrants are outstanding as of June 30, 2001.

     On  December  14,  1999,  the  Company  completed  a private  placement  of
2,500,000 shares of its common stock at $3.00 per share to several investors and
received net proceeds of $7,220,000.  Substantially all of the net proceeds were
used to redeem the Series F Stock as described above.

            Notes to Consolidated Financial Statements - (Continued)

     In  conjunction  with this  private  placement,  the Company  agreed to the
following covenants:

-    The Company agreed to refrain from entering into certain  transactions with
     persons  closely related to the Company,  including its executive  officers
     and  directors,  without the prior approval of the investors in the private
     placement.  The investors in this  financing  agreed not to withhold  their
     approval unreasonably.

-    The Company  agreed that without the prior  consent of such  investors,  it
     would not sell its  business to anyone that is an affiliate of the Company,
     unless the sale is for  consideration at least equal to (a) the fair market
     value in the event of a sale of assets (as  determined in good faith by the
     Company's  board of directors) or (b) the then current  market price in the
     event of a sale of stock.

-    The Company agreed that it would not amend its certificate of incorporation
     or by-laws in a manner that would adversely affect such investors,  without
     the prior approval of the investors. The investors in this financing agreed
     not to withhold their approval unreasonably.

     These  covenants  will cease to apply at such time as the investors in this
financing and their  affiliates  beneficially  own less than 5% of the Company's
common stock. Such investors in the aggregate currently continue to beneficially
own more than 5% of the Company's  outstanding  common stock. Prior to the time,
if ever,  when the investors'  equity interest falls below 5%, the investors may
waive any one or more of the covenants  set forth in the Company's  Common Stock
Purchase Agreement.

     On February 16, 2000, the Company  completed  another private  placement of
2,350,000  shares of common stock at $16.00 per share to several  investors  and
received net proceeds of $35,443,000.

     Under the terms of the  Company's  1983 Stock Option Plan,  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" and,  together
with the 1983 Plan, the "Plans") 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. At the Company's annual meeting of stockholders,
which was held on December 6, 2000,  the  stockholders  approved an amendment to
the 1992 Stock Option Plan to authorize an additional 5,000,000 shares of common
stock for possible future issuance. At June 30, 2001, 4,630,875 shares of common
stock were still available for future grant and 6,908,625 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 had been a Director  prior to July 1st of each year is  granted,  on
the first business day of July of each year, an option to purchase shares of the
Company's  common  stock at fair market  value on the grant date,  the amount of
which is determined at the discretion of the Company's  Board of Directors.  For
July 1, 2001,  stock options covering 60,000 shares of common stock options were
granted to these Directors.

     In April 2000,  David M. Goldenberg,  the Company's  Chairman and his wife,
Cynthia L. Sullivan,  the Company's President and Chief Executive Officer,  paid
to the Company the sum of $657,722 in accordance  with the provisions of Section
16(b) of the Securities  Exchange Act of 1934. Such amount  represents the short
swing  profit  realized  as a result of  purchase  and sale  transactions  which
occurred  within a six month  period.  The  Company  recorded  such  amount as a
contribution of capital in its June 30, 2000 consolidated balance sheet as it is
related to a transaction with the Company's equity.

     The Company has adopted the disclosure-only provisions of SFAS No. 123, and
applies APB Opinion No. 25 in accounting for its plans and, accordingly, has not
recognized  compensation  cost for its  stock  option  plan in its  consolidated
financial statements, except for compensation cost associated with 325,000 stock
options  issued at an  exercise  price lower than the stock price on the date of
grant as described further below. Had the Company  determined  compensation cost
based on the fair value at the grant date consistent with the provisions of SFAS
No. 123, the Company's net loss allocable to common shareholders and related per
share amounts would have been the pro forma amounts indicated below:


                                            2001           2000          1999

     The fair value of each option granted during the three years ended June 30,
2001 is  estimated on the date of grant using the  Black-Scholes  option-pricing
model with the following weighted average assumptions: (I) dividend yield of 0%,
(II) expected term of 8 years for June 30, 2001,  2000, and 1999, (III) expected
volatility  of 129% at June 30, 2001,  126% at June 30, 2000 and 80% at June 30,
1999, and (IV) a risk-free interest rate of 5.01%, 5.90% and 5.06% for the years
ended June 30, 2001,  2000, and 1999,  respectively.  The weighted  average fair
value at the date of grant for options  granted  during the years ended June 30,
2001, 2000 and 1999 was $16.94, $11.89 and $1.26 per share, respectively.

     On May 18, 2000 the Board of  Directors  approved  granting an aggregate of
325,000 stock options to Dr. David M.  Goldenberg  and Cynthia L. Sullivan which
were subject to  shareholder  approval.  Such  approval  was  obtained  from the
shareholders  during  December  2000.  The stock  options  were  granted with an
exercise price of $17.75 representing the stock price on the day of the Board of
Directors' approval.  The difference in the stock price on that date as compared
to the stock price of $19.06 on the date the shareholders  approval was obtained
resulted in compensation cost of $425,750 which is being expensed by the Company
over the  vesting  period of 4 years.  During  fiscal  year  2001,  the  Company
recorded $115,310 as a general and administrative expense.

8.     Income Taxes

     The Company  utilizes SFAS No. 109,  Accounting for Income Taxes to account
for income taxes.  During fiscal 2001,  the Company  recognized a tax benefit of
$803,315  from  the  sale  of  $10,106,000  of New  Jersey  net  operating  loss
carryforwards. 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, 2001, 2000, and 1999 are presented below:


                                              2001          2000           1999
                                      ------------  ------------   ------------
Deferred tax assets:
  Net operating loss carry forwards   $ 48,036,000  $ 46,455,000   $ 37,722,000
  Research and development credits       4,718,000     4,500,000      4,364,000
  Property and equipment                 1,248,000     1,058,000        838,000
  Other                                  1,429,000       746,000        383,000
                                      ------------  ------------   ------------
  Total                                 55,431,000    52,759,000     43,307,000

  Valuation allowance                  (55,431,000)  (52,759,000)   (43,307,000)
                                      ------------  ------------   ------------

  Net deferred taxes                  $         --  $         --   $        --
                                      ============  ============   ============

     A valuation allowance is provided when it is more likely than not that some
portion or all of the deferred tax assets will not be  realized.  The  valuation
allowances for fiscal years 2001,  2000 and 1999 have been applied to offset the
deferred tax assets in  recognition  of the  uncertainty  that such tax benefits
will be realized  as the  Company  continues  to incur  losses.  The tax benefit
assumed  using the  federal  statutory  tax rate of 34% has been  reduced  to an
actual  benefit  of  zero  due  principally  to  the  aforementioned   valuation
allowance.  The differences between book income and tax income primarily relates
to exercise of employee stock options and depreciation.

     At  June  30,  2001,   the  Company  has  available   net  operating   loss
carryforwards  for  federal  income  tax  reporting  purposes  of  approximately
$128,000,000  and for state  income  tax  reporting  purposes  of  approximately
$106,000,000,  which  expire at  various  dates  between  fiscal  2002 and 2022.
Pursuant to Section 382 of the Internal  Revenue Code of 1986,  as amended,  the
annual  utilization  of a  company's  net  operating  loss and  research  credit
carryforwards may be limited if the Company experiences a change in ownership of
more  than 50  percentage  points  within a  three-year  period.  As a result of
certain financing arrangements,  the Company may have experienced such ownership
changes.  Accordingly,  the Company's net operating loss carryforwards available
to

                                       36



                       Immunomedics, Inc. and subsidiaries
            Notes to Consolidated Financial Statements - (Continued)

offset future federal  taxable income arising before such ownership  changes may
be  limited.  Similarly,  the Company may be  restricted  in using its  research
credit  carryforwards  arising  before such  ownership  changes to offset future
federal  income tax  expense.  Of the  deferred  tax asset  valuation  allowance
related  to the net  operating  loss  carryforwards,  approximately  $18,200,000
relates to a tax deduction for  non-qualified  stock  options.  The Company will
increase capital  contributed in excess of par when these benefits are deemed to
be more likely than not to be realized for tax purposes.  The net operating loss
carryforwards  for  federal  income tax  reporting  purposes  referred  to above
excludes certain losses from the Company's operations in The Netherlands,  which
may also be  limited.  The Company  made no payments of federal or state  income
taxes during the years ended June 30, 2001, 2000 and 1999.

9.     Related-Party Transactions

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

     Dr.  Goldenberg  currently  serves as the  President of CMMI pursuant to an
employment  agreement and during fiscal 2001 devoted 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. Dr. Hans Hansen, an officer of the Company, is an adjunct
member of CMMI.

     CMMI is currently conducting basic research and pre-clinical evaluations in
a number of areas of  potential  interest  to the  Company.  Under  its  license
agreement  with CMMI,  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  determined  at the time the license is
obtained.

     The license  agreement  terminates  on January 21,  2002,  with the Company
having the right to seek  good-faith  negotiation to extend the agreement for an
additional  five-year period. 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. Pursuant to a collaborative research and license agreement, dated
as of January 21,  1997,  between the Company and CMMI,  the Company has paid to
CMMI an annual  license fee of $200,000 in each of the fiscal  years 2001,  2000
and 1999.

     The  Company has  reimbursed  CMMI for  expenses  incurred on behalf of the
Company,  including  amounts  incurred  pursuant to research  contracts,  in the
amounts of approximately  $155,000,  $128,000 and $45,000 during the years ended
June 30, 2001, 2000 and 1999, respectively.  The Company also provides CMMI with
laboratory materials and supplies.

     During each of the fiscal  years 2001 and 1999,  the Board of  Directors of
the  Company  authorized  grants to CMMI of  $200,000  to support  research  and
pre-clinical  work being  performed  at CMMI,  such  grants to be  expended in a
manner deemed appropriate by the Board of Trustees of CMMI.

10.    License and Distribution Agreements

     On November 24, 1997,  the Company  entered into a  Distribution  Agreement
with Eli Lilly  Deutschland GmbH ("Lilly")  pursuant to which Lilly packages and
distributes  LeukoScan  within the countries  comprising  the European Union and
certain  other  countries  subject  to receipt of  regulatory  approvals.  Also,
effective April 6, 1998, Lilly began packaging and distributing  CEA-Scan within
the countries  comprising the European  Union.  The Company pays Lilly a service
fee based  primarily  on the number of units of product  packaged  and  shipped.
Lilly has notified the Company  that it intends to  terminate  its  Distribution
Agreement  with the  Company as of the end of the  current  calendar  year.  The
Company expects to establish alternate distribution arrangements by that time.

     Effective  as of April 6, 1998,  the  Company  appointed  a  subsidiary  of
AmeriSourceBergen  Corporation  (formerly  Bergen  Brunswick) as a non-exclusive
distributor  of  CEA-Scan  in the U.S.  Such  subsidiary  (currently  Integrated
Commercialization  Solutions, Inc. ("ICS")) serves as an agent of the Company in
providing  product  support   services,   including   customer  service,   order
management, distribution, invoicing and collections.

     On December 21, 1998, the Company received  $300,000 in final settlement of
all claims between the Company and  Mallinckrodt,  Inc. and its affiliate  under
the prior  distribution  agreements,  which were  terminated in April 1998. This
amount was recognized as other revenue in fiscal year 1999.

     The Company, through its 80% owned subsidiary, IMG Technology, LLC ("IMG"),
has formed a joint venture with Coulter Corporation  ("Beckman Coulter") for the
purpose of developing targeted cancer therapeutics.  The joint venture, known as
IBC  Pharmaceuticals,  LLC ("IBC") was organized as a Delaware limited liability
company.  On March 5, 1999 the  Company  contributed  to IBC,  on behalf of IMG,
certain rights to its proprietary humanized antibodies against the cancer marker
carcinoembryonic  antigen  (which had a financial  reporting  carrying  value of
zero),  which  is  used  in  its  CEA-Cide  therapeutic,   and  Beckman  Coulter
contributed to IBC certain rights to its bispecific  targeting technology called
the  "Affinity  Enhancement  System" or AES.  The  Company  assigned  its rights
pursuant  to the terms of a license  agreement  with IBC dated  March 5, 1999 in
exchange  for the grant to IMG of its  interest  in IBC  ("Immunomedics  License
Agreement").  Beckman  Coulter  received its interest in IBC in exchange for its
contribution. The license granted to IBC is a worldwide, royalty free, exclusive
license  which is limited to the "IBC Field" with  respect to the  "Immunomedics
Patent Property" and the "Immunomedics Biotechnology Assets," as those terms are
defined in the Immunomedics  License  Agreement.  Additionally on March 5, 1999,
several investors contributed $3,000,000 to IBC in exchange for a 7% interest in
the venture.  IMG's and Beckman Coulter's interests in IBC are 49.55% and 43.45%
respectively.  Beckman Coulter,  IMG and the investors entered into an operating
agreement  (the "IBC  Operating  Agreement")  which  establishes  the rights and
obligations  of the  respective  members.  Under the terms of the IBC  Operating
Agreement,  neither IMG nor Beckman Coulter may sell any portion of its interest
in IBC without  first  providing  the other with a right of first  refusal  with
respect to such sale,  provided that after a public  offering of IBC securities,
IMG and Beckman Coulter will be permitted to sell up to 20% of their  respective
interests in IBC free of such right of first refusal.  IMG is a Delaware limited
liability  company owned 80% by the Company and 20% by Dr. David M.  Goldenberg.
Dr.  Goldenberg  received his interest  pursuant to the terms of his  employment
agreement with the Company.  IMG is intended to be a single purpose entity,  its
sole asset being its interest in IBC. Dr.

                       Immunomedics, Inc. and subsidiaries
            Notes to Consolidated Financial Statements - (Continued)

Goldenberg and IMG have entered into an operating  agreement (the "IMG Operating
Agreement")  that  establishes  their relative rights and obligations  (see Note
11). In  connection  with Dr.  Goldenberg's  receipt of an interest in IMG,  the
Company recognized  $182,000 of compensation  expense in fiscal year 1999, based
on the fair value of technology transferred, and has reflected his interest as a
minority interest in the consolidated  financial  statements.  There has been no
changes to the minority interest since initially  recorded.  Dr. Goldenberg also
serves as Chairman of the Board of IBC.

     On February  29,  2000,  the  Company  signed a Letter  Agreement  with KOL
Bio-Medical Instruments,  Inc. ("KOL"),  granting KOL exclusive rights to market
and sell CEA-Scan in the northeastern  U.S. This agreement was terminated by the
Company on April 19, 2001 and all obligations  pursuant to the Letter  Agreement
were satisfied upon termination.

     On  December  17,  2000,  the  Company  signed a  Development  and  License
Agreement  with Amgen Inc.  ("Amgen").  The  Agreement  provides  Amgen with the
exclusive rights to clinical development and  commercialization of the Company's
naked CD22 antibody  product,  epratuzumab,  for the treatment of  non-Hodgkin's
lymphoma in the territories of North America and Australia.

     Pursuant  to the Amgen  Development  and  License  Agreement,  the  Company
received an up-front  payment of  $18,000,000  from Amgen on the closing date of
February 1, 2001 and could  potentially  receive clinical  milestones and future
royalties. The up-front payment of $18,000,000 is being recognized as revenue of
$750,000 per month over a period of 24 months, beginning February 2001, which is
management's  best  estimate of the period of time  required  for the parties to
fulfill their obligations under the Development and License Agreement related to
the manufacture of epratuzumab.  Accordingly,  the Company recognized $3,750,000
as royalties  and license fee revenue  during  fiscal year 2001.  The  remaining
$14,250,000  is  recorded  as  "Deferred  revenue",   of  which  $9,000,000  and
$5,250,000  is  classified  as current  and  non-current,  respectively,  in the
accompanying consolidated balance sheet at June 30, 2001.

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.  This
Agreement  was amended on July 1, 2001,  pursuant to which Dr.  Goldenberg  will
receive  an annual  minimum  base  salary  of  $275,000,  an annual  bonus to be
determined  by the Board of Directors  but in no event less than 20% of the base
salary,  annual stock options grants  covering at least 150,000 shares of common
stock,  other  benefits  and certain  change of control  protections.  Under the
Agreement  as  amended,  the  Company  has  agreed  to extend  Dr.  Goldenberg's
employment  agreement  for a five-year  period  which  expires on June 30, 2006.
Further,  the Company  acknowledged  and  approved Dr.  Goldenberg's  continuing
involvement with CMMI and IBC.

     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,

                                       39



                       Immunomedics, Inc. and subsidiaries
            Notes to Consolidated Financial Statements - (Continued)

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  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,
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.  For each of the years ended June 30, 2001,
2000 and 1999, the Company paid Dr.  Goldenberg the minimum  required payment of
$100,000.  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 three years)
of any defined  Undeveloped Assets of the Company which are not budgeted as part
of the Company's strategic plan.  Pursuant thereto,  Dr. Goldenberg received his
interest in IMG (See Note 10).

     On March 20,  2001,  the  Company and Cynthia L.  Sullivan  entered  into a
five-year employment agreement (the "Agreement")  pursuant to which Ms. Sullivan
has the option to  terminate  if the  Agreement is not renewed by the Company by
March 8, 2004.  Pursuant to this agreement,  Ms. Sullivan will receive an annual
minimum base salary of $275,000,  an annual bonus in an amount to be  determined
by the Board of Directors  but in no event less than 20% of the base salary,  an
annual grant of stock  options  covering not less than 150,000  shares of common
stock per year and certain other benefits and change of control protections.

     The Company is obligated  under an operating  lease for facilities used for
research and development,  manufacturing  and office space. On May 29, 1998, the
Company  exercised  its right to renew  for an  additional  term of three  years
expiring in May 2002 at a base  annual rate of  $441,000.  In August  2001,  the
Company renewed for an additional term of twenty years expiring in May 2022 at a
base  annual  rate of  $545,000,  which is fixed  for the first  five  years and
increases  thereafter  every five years,  which  includes an  additional  15,000
square feet.  Rental expense related to this lease was  approximately  $441,000,
$441,000  and  $425,000 in fiscal  years  2001,  2000,  and 1999,  respectively.
Including the extension of the facility  lease as described  above,  the minimum
lease commitments for facilities are as follows for fiscal years:

              Thereafter......................... $11,073,000

     The  Company is a party to 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
consolidated financial position and results of operations.

12.    Debt

     On October  28,  1998,  the Company  entered  into an  Equipment  Financing
Agreement  with the New  England  Capital  Corporation,  pursuant  to which  the
Company has received  $450,000,  at the interest rate of 9.52% per annum,  to be
repaid  over a 36-month  period.  The  proceeds of such  financing  were used to
exercise the early purchase  options for equipment  previously  leased through a
master lease  agreement.  The  financing is secured by various  equipment and an
irrevocable letter of credit in the amount of $225,000.  The letter of credit is
collateralized  by a cash deposit of an  equivalent  amount which is included in
"Other long- term assets" on the  accompanying  consolidated  balance sheet.  At
June 30, 2001, the Company's  indebtedness  under this agreement was $70,412 due
in equal monthly  installments over the next 5 months. In the fiscal years ended
June 30, 2001,  2000 and 1999,  the Company paid  $14,974,  $29,275 and $23,162,
respectively, in interest under this agreement.

13.      Geographic Segments

     The Company  manages its operations as one line of business of researching,
developing, manufacturing and marketing biopharmaceutical products, particularly
antibody-based  diagnostics and therapeutics for cancer and infectious diseases,
and it currently reports as a single industry  segment.  The Company markets and
sells its products in the U.S. and throughout Europe.  During fiscal years 2001,
2000  and  1999,  no  product  sales  from a  single  customer  exceeded  10% of
consolidated product sales.

     The following table presents financial  information based on the geographic
location of the facilities of Immunomedics, Inc. as of and for the years ended:

                          INDEPENDENT AUDITORS' REPORT


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

We have audited the  accompanying  consolidated  balance sheets of Immunomedics,
Inc. and subsidiaries as of June 30, 2001 and 2000, and the related consolidated
statements  of  operations  and  comprehensive  loss,  changes in  stockholders'
equity, and cash flows for each of the years in the three-year period ended June
30, 2001. 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 auditing standards generally accepted
in the  United  States of  America.  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.
and  subsidiaries  as of June  30,  2001  and  2000,  and the  results  of their
operations and their cash flows for each of the years in the  three-year  period
ended June 30, 2001, in conformity with accounting principles generally accepted
in the United States of America.

     for executives of the same level and responsibility as Executive.

          (f) Waiver of  Compensation  for Board Service.  Executive  waives any
     right to  receive  additional  compensation  in  respect  of  service  as a
     director  of the  Company  or a member  of any  committees  of the Board of
     Directors,  and agrees that the  consideration  set forth in this Agreement

     Executive by the Company.

          (g) Waiver of Compensation From Other Sources.  Executive acknowledges
     and agrees  that any  compensation,  property,  or other  emoluments  to be
     received by her, directly or indirectly, in connection with any transaction

     4. Termination of Employment.

          (a) Termination.  The Company may terminate Executive's employment for
     Cause (as defined below) or for any breach of this Agreement, in which case
     the provisions of Section 4(b) of this Agreement  shall apply.  The Company
     may also  terminate  Executive's  employment  in the  event of  executive's
     Disability (as defined below), in which case the provisions of Section 4(c)
     of  this  Agreement  shall  apply.  The  Company  may  also  terminate  the
     Executive's employment for any other reason by written notice to Executive,
     in which case the provisions of Section 4(d) of this Agreement shall apply.
     If  Executive's  employment is terminated by reason of  Executive's  death,
     retirement or voluntary resignation, the provisions of Section 4(b) of this
     Agreement shall apply.

          (b)  Termination  for  Cause;   Termination  by  Reason  of  Death  or
     Retirement  or  Voluntary  Resignation.   In  the  event  that  Executive's
     employment  hereunder is  terminated  during the Term(s) by the Company for
     Cause (as defined below),  by reason of Executive's  death or retirement or
     by reason of Executive's voluntary resignation,  then the Company shall pay
     to Executive the Base Salary through such date of termination. For purposes
     of this Agreement,  "Cause" shall mean (i) conviction of any crime (whether
     or not involving  the Company)  constituting  a felony in the  jurisdiction
     involved; (ii) engaging in any substantiated act involving moral turpitude;
     (iii) engaging in any act which,  in each case,  subjects,  or if generally
     known, would subject the Company to public ridicule or embarrassment;  (iv)
     gross  neglect or  misconduct  in the  performance  of  Executive's  duties
     hereunder;  (v)  willful  failure or refusal to perform  such duties as may
     reasonably  be  delegated  to  Executive;  or (vi)  material  breach of any
     provision of this  Agreement by  Executive;  provided,  however,  that with
     respect to clauses (iv), (v) or (vi), Executive shall have received written
     notice  from the  Company  setting  forth the alleged act or failure to act
     constituting "Cause" hereunder, and Executive shall not have cured such act
     or refusal to act within 10 business days of her actual receipt of notice.

          (c) Unavailability. If, as a result of Executive's incapacity due to a
     serious health (physical or mental) condition or as a result of Executive's
     unavailability for work for reason other than unexcused absence,  Executive
     shall have been absent from  Executive's  duties  hereunder  on a full time
     basis for either (i) one hundred twenty (120) days within any three hundred

                                       54


     sixty-five  (365) day period,  or (ii) ninety (90)  consecutive  days,  the
     Company   may    terminate    Executive's    employment    hereunder    for
     "Unavailability."  In that event,  the Company shall pay to Executive  only
     the Base Salary  through such date of  termination.  During any period that
     Executive  fails to perform  Executive's  duties  hereunder  as a result of
     incapacity  due to a serious  health  (physical  or mental)  condition,  (a
     "Disability Period"),  Executive shall continue to receive the compensation
     and  benefits  provided by Section 3 of this  Agreement  until  Executive's
     employment hereunder is terminated;  provided,  however, that the amount of
     compensation  and  benefits  received by  Executive  during the  Disability
     Period  shall be  reduced  by the  aggregate  amounts,  if any,  payable to
     Executive  under  disability  benefit  plans and programs of the Company or
     under the Social Security  disability  insurance  program and provided that
     any time that Executive fails to perform  Executive's duties hereunder as a
     result of incapacity due to a serious health (physical or mental) condition
     shall be deemed and  designated  to be leave under the  federal  Family and
     Medical  Leave Act and the New Jersey  Family Leave Act,  which leave shall
     run concurrently  with any compensated  leave provided under this contract,
     other insurance  plans, or under  applicable  state and federal  disability
     programs.  Executive  further  acknowledges  and agrees that she is a "key"
     employee as defined under 29 C.F.R.  ss.825.217(c)  and that her rights, if
     any, to reinstatement to her position are thereby limited.

          (d)  Termination For Any Other Reason.  In the event that  Executive's
     employment  hereunder  is  terminated  during the Term for any reason other
     than as  provided  in  Section  4(b) or 4(c) of this  Agreement,  then  the
     Company  shall  continue  for a period of four (4)  years  the  Executive's
     health and life insurance  under Section 3(d) and shall pay to Executive in
     lieu  of  any  further  compensation  and  benefits  under  this  Agreement
     "Severance  Pay," as defined  below.  , "Severance  Pay" shall equal to the
     highest  Base  Salary paid to the  Executive  during any of the three prior
     years,  the  highest  Bonus paid to the  Executive  during any of the three
     prior years,  and the stock  options that  Executive  would have  otherwise
     received during the period beginning on such date of termination and ending
     on the later of  twenty-four  (24) months from the  effective  date of such
     termination and the last day of the Term. Such Severance Pay shall be paid,
     at the  Executive's  option (i) commencing with such date of termination at
     the times and in the  amounts  such Base  Salary,  Bonus and stock  options
     would  have  been paid or (ii) in a lump sum  present  value at the time of
     termination.  Notwithstanding anything to the contrary contained herein, in
     the event that Executive shall elect to be paid Severance Pay over time and
     yet  breach  Section 5 or 6 of this  Agreement,  in  addition  to any other
     remedies  the  Company  may  have  in the  event  Executive  breaches  this
     Agreement,  the  Company's  obligation  pursuant  to this  Section  4(d) to
     continue  such salary  shall cease and  Executive's  rights  thereto  shall
     terminate and shall be forfeited.  Similarly,  notwithstanding  anything to
     the contrary  contained  herein, in the event that Executive shall elect to
     be paid Severance Pay in a lump sum yet thereafter breach Section 5 or 6 of
     this Agreement,  the Company shall be entitled to pro-rata  disgorgement of
     the lump  sum  severance  payments  already  made,  calculated  to  provide
     disgorgement  of all  amounts  corresponding  to the period  following  the
     Executive's initial breach of Section 5 or 6

          (e) Change of  Control.  A change of control of the Company is defined
     (i) an involuntary  change in the composition,  as of the effective date of
     this  Agreement,  of more than  thirty-three  percent (33%) of the Board of
     Directors of the Company or (ii) any person,  entity or combination thereof
     (other than the members of the Goldenberg family) controlling, individually
     or collectively  through ownership,  assignment,  voting proxy or the like,
     25% or more percent of the outstanding  voting shares ordinarily having the
     right to vote for the  election  of the  directors  of the  Company  or the
     combined   voting  power  thereof  or  (iii)  there  is  a  liquidation  or
     dissolution of the Company  approved by the shareholders or (iv) there is a

                                       55


     sale of all or substantially all of the assets of the Company.  A change of
     control   immediately  vests  all  previously  stock  options  awarded  the
     Executive.  Additionally, in the event that a Change of Control occurs, the
     Executive,  if the  Company  and the  Executive  agree,  may remain in this
     capacity for up to one year before either a new contract is  consummated or
     the Executive  elects to receive  severance as provided in Section 4(d). If
     the Company and the  Executive do not agree to the  Executive  remaining in
     this capacity for the one-year period beginning with the change of control,
     then the Executive's  employment shall terminate and the Executive shall be
     entitled to severance under Section 4(d).

          (f) No Further Liability; Release. Payment made and performance by the
     Company in accordance  with this Section 4 shall operate to fully discharge
     and  release  the  Company   and  its   directors,   officers,   employees,
     subsidiaries,  affiliates,  stockholders,  successors,  assigns, agents and
     representatives  from any further  obligation or liability  with respect to
     Executive's  employment and  termination  of employment.  Other than paying
     Executive's  Base Salary and any bonuses through the date of termination of
     Executive's  employment and making any severance payment pursuant to and in
     accordance  with  this  Section  4 (as  applicable),  the  Company  and its
     directors,  officers, employees,  subsidiaries,  affiliates,  stockholders,
     successors,  assigns,  agents  and  representatives  shall  have no further
     obligation  or  liability  to  Executive  or any other  person  under  this
     Agreement. The Company shall have the right to condition the payment of any
     severance  pursuant to this Section 4 upon the delivery by Executive to the
     Company of a release in form and substance  satisfactory  to the Company of
     any  and  all  claims  Executive  may  have  against  the  Company  and its
     directors,  officers, employees,  subsidiaries,  affiliates,  stockholders,
     employment by the Company and the termination of such employment.

     5. Exclusive Employment; Noncompetition.

          (a) No Conflict; No Other Employment. During the period of Executive's
     employment  with the  Company,  Executive  shall  not:  (i)  engage  in any
     activity  which   conflicts  or  interferes  with  or  derogates  from  the
     performance of Executive's  duties  hereunder nor shall Executive engage in
     any other  business  activity,  whether or not such  business  activity  is
     pursued for gain or profit,  except as approved in advance in writing  from
     the Board of Directors of the Company,  provided,  however,  that Executive
     shall be entitled to manage her personal  investments and otherwise  attend
     to personal affairs, including charitable activities, in a manner that does
     not unreasonably  interfere with her  responsibilities  hereunder,  or (ii)
     accept any other  employment,  whether as an executive or  consultant or in
     any other  capacity,  and  whether  or not  compensated  therefore,  unless
     Executive receives the prior approval of the Board of Directors.

          (b) No Competition. Executive recognizes the highly Competitive nature
     of the Company's  business and that  Executive's  position with the Company
     and access to and use of the Company's confidential records and proprietary
     information  renders  Executive  special and unique.  Without  limiting the
     generality  of the  provisions  of Section 2(b) or 5(a) of this  Agreement,
     during  the Term and for a period of two years  after  the  termination  of
     Executive's  employment  with the Company for any reason,  Executive  shall
     not,  directly  or  indirectly,   own,  manage,   operate,  join,  control,
     participate in, invest in or otherwise be connected or associated  with, in
     any  manner,  including  as an  officer,  director,  employee,  independent
     contractor,  member,  partner,  consultant,   advisor,  agent,  proprietor,
     trustee or investor,  any Competing  Business located in the United States;
     provided,  however,  that  ownership  of 20% or less of the  stock or other
     securities  of a  corporation,  the stock of which is listed on a  national
     securities  exchange  or is quoted on The Nasdaq  Stock  Market,  shall not
     constitute  a breach of this  Section 4, so long as  Executive  does not in
     fact have the power to  control,  or direct  the  management  of, or is not
     otherwise associated with, such corporation.




                                       56


          For purposes  hereof,  the term  "Competing  Business"  shall mean any
     business or venture  which  engages in a business  that  competes  with the
     business of any Related  Entity.  The term Related Entity shall include all
     operating  subsidiaries  of the Company and all other business  entities in
     which  the  Company,  alone or in  conjunction  with  any of its  operating
     subsidiaries, has an ownership interest of greater than thirty-three (33%).
     The  "Competing  Business"  is  restricted  to  the  field  of  therapeutic
     antibodies for cancer.

          (c) No Solicitation of Employment. During the Term and for a period of
     two years thereafter, Executive shall not solicit or encourage any employee
     of the Company or any Related  Entity to leave the Company or such  Related
     Entity for any reason, nor assist any business in doing so, nor employ such
     an employee in a Competing Business or any other business.

          (d) Company Customers.  Executive shall not, during the Term and for a
     period of one year  thereafter,  except as  required  by the Company in the
     performance  by Executive of her duties under this  Agreement,  directly or
     indirectly,  on behalf of a  Competing  Business,  contact,  solicit  or do
     business  with any  "customers"  (as  defined  below) of the Company or any
     Related  Entity  for the  purpose  of selling  or  licensing  any  product,
     service,  or technology then sold or licensed by the Company or any Related
     Entity  proposed  to be sold or  licensed  by the  Company  or any  Related
     Entity. For the purposes of the provisions of this Section 5(d), "customer"
     shall include any entity that, within two years prior to the termination of
     Executive's  employment  hereunder,  purchased  or  licensed  any  product,
     service,  or technology  from the Company or any Related  Entity.  The term
     "customer" also includes any former  customer or potential  customer of the
     Company or any Related  Entity which the Company or any Related  Entity has
     solicited  within  two  years  prior  to  the  termination  of  Executive's
     employment  hereunder  for the purpose of selling or licensing any product,
     service,  or technology then sold or licensed by the Company or proposed to
     be sold or licensed.

          (e)  Executive   Acknowledgment.   Executive   understands   that  the
     provisions  of this Section 5 may limit her ability to earn a livelihood in
     a business  that  competes  with the business of the Company or its Related
     Entities  but  nevertheless   agrees  and  hereby   acknowledges  that  the
     consideration  provided  under this  Agreement is sufficient to justify the
     restrictions contained in such provisions.  In consideration thereof and in
     light of Executive's education, skills and abilities, Executive agrees that
     she will not  assert in any forum  that such  provisions  prevent  her from
     earning a living or otherwise are void or  unenforceable  or should be held
     void or unenforceable.

     6. Confidential Information.

          (a)  Existence  of  Confidential  Information.  The  Company  and each
     Related  Entity owns and has developed  and compiled,  and will develop and
     compile,  certain proprietary techniques and confidential information which
     have  great  value  to  its  business   (referred  to  in  this  Agreement,
     collectively,  as  "Confidential  Information").  Confidential  Information
     includes  not only  information  disclosed  by the  Company or any  Related
     Entity to Executive, but also information developed or learned by Executive
     during  the course or as a result of  employment  with the  Company,  which
     information shall be the property of the Company or the applicable  Related
     Entity. Confidential Information includes all information that has or could
     have  commercial  value or other  utility  in the  businesses  in which the
     Company or any Related Entity is engaged or contemplates  engaging, and all
     information of which the  unauthorized  disclosure  could be detrimental to
     the  interests  of the Company or any Related  Entity,  whether or not such

                                       57


     information is  specifically  labeled as  Confidential  Information by such
     entity. By way of example and without limitation,  Confidential Information
     includes any and all information developed,  obtained, licensed by or to or
     owned by the  Company  or any  Related  Entity  concerning  trade  secrets,
     techniques, know-how (including designs, plans, procedures,  merchandising,
     marketing,  distribution and warehousing know how, processes,  and research
     records),  software, computer programs and designs,  development tools, all
     proprietary property,  and any other intellectual property created, used or
     sold (through a license or  otherwise) by the Company or a Related  Entity,

          (b) Protection of Confidential Information. Executive acknowledges and
     agrees that in the performance of Executive's  duties hereunder the Company
     and the  Related  Entities  may  disclose  to and  entrust  Executive  with
     Confidential  Information which is the exclusive  property of such entities
     and  which  Executive  may  possess  or  use  only  in the  performance  of
     Executive's  duties  to  the  Company.  Executive  also  acknowledges  that
     Executive  is  aware  that  the  unauthorized  disclosure  of  Confidential
     Information,  among  other  things,  may be  prejudicial  to the  Company's
     interests  or those of a Related  Entity,  an  invasion  of privacy  and an
     improper  disclosure of trade  secrets.  Executive  shall not,  directly or
     indirectly, use, make available, sell, disclose or otherwise communicate to
     any  corporation,  partnership  or other entity,  individual or other third
     party, other than in the course of Executive's  assigned duties and for the
     benefit of the Company,  any  Confidential  Information,  either during the
     Term or thereafter.  In the event Executive  desires to publish the results
     of  Executive's  work for or  experiences  with the  Company or any Related
     Entity through  literature,  interviews or speeches,  Executive will submit
     requests for such interviews or such literature or speeches to the Chairman
     of  the  Board  of  Directors  at  least  fourteen  (14)  days  before  any
     anticipated  dissemination  of  such  information  for a  determination  of
     whether such disclosure is in the best interests of the Company,  including
     whether such  disclosure  may impair trade secret  status or  constitute an
     invasion of privacy. Executive agrees not to publish, disclose or otherwise
     disseminate  such  information  without the prior  written  approval of the
     Chairman of the Board the Company.

          (c) Delivery of Records, Etc. In the event Executive's employment with
     the  Company  ceases for any  reason,  Executive  will not remove  from the
     Company's  premises  without its prior written consent any records (written
     or  electronic),  files,  drawings,  documents,  equipment,  materials  and
     writings  received  from,  created for or  belonging  to the Company or any
     Related  Entity,  including  those which relate to or contain  Confidential
     Information, or any copies thereof Upon request or when employment with the
     Company  terminates,  Executive  will  immediately  deliver the same to the
     Company.

     enforceable by, and may be assigned by the Company to, any purchaser of all
     or substantially all of the Company's  business or assets, any successor to
     the  Company  or any  assignee  thereof  (whether  direct or  indirect,  by
     purchase, merger, consolidation or otherwise).

                                       58


          (b) Executive. Executive's rights and obligations under this Agreement
     shall not be transferable by Executive by assignment or otherwise,  and any
     purported  assignment,  transfer  or  delegation  thereof  shall  be  void;
     provided, however, that if Executive shall die, all amounts then payable to
     Executive  hereunder  shall be paid in  accordance  with the  terms of this
     Agreement to Executive's devisee, legatee or other designee or, if there be
     no such designee, to Executive's estate.

     8. Miscellaneous.

          (a) Other Obligations.  Executive represents and warrants that neither
     Executive's  employment  with the Company nor  Executive's  performance  of
     Executive's   obligations  hereunder  will  conflict  with  or  violate  or
     otherwise are inconsistent with any other obligations,  legal or otherwise,
     which  Executive may have.  Executive  covenants that she shall perform her
     duties hereunder in a professional manner and not in conflict or violation,
     otherwise  inconsistent with other  obligations  legal or otherwise,  which
     Executive may have.

     proprietary   information,   trade   secrets  and   confidential   business
     information belonging to all prior employers.

          (c) Cooperation.  Following termination of employment with the Company
     for any reason, Executive shall cooperate with the Company, as requested by
     the Company, to affect a transition of Executive's  responsibilities and to
     ensure that the Company is aware of all matters being handled by Executive.

          (d) No Duty to Mitigate.  Executive shall be under no duty to mitigate
     any losses or damage to the Company with respect to any  severance or other
     amounts payable pursuant to Section 4 of this Agreement.

          (e)  Protection  of  Reputation.   During  the  Term  and  thereafter,
     Executive  agrees that she will take no action which is intended,  or would
     reasonably  be  expected,  to harm the Company or its  reputation  or which
     would  reasonably be expected to lead to unwanted or unfavorable  publicity
     to the Company.

          (f) Governing Law. This  Agreement  shall be governed by and construed
     in  accordance  with the internal  laws of the State of New Jersey  without
     regard to principles of the conflict of laws thereof.

          (g) Jurisdiction; Forum. Each party hereto consents and submits to the
     exclusive  jurisdiction  of any state or federal court sitting in the State
     of New Jersey in connection  with any dispute arising out of or relating to
     this Agreement,  except where governed by paragraph 8(p). Each party hereto
     waives any  objection  to the laying of venue in such  courts and any claim
     that any such  action has been  brought in an  inconvenient  forum.  To the
     extent  permitted by law, any judgment in respect of a dispute  arising out
     of or relating to this Agreement may be enforced in any other  jurisdiction
     within or outside the United  States by suit on the  judgment,  a certified
     copy of such judgment being  conclusive  evidence of the fact and amount of
     such judgment.

                                       59


          (h)  Waiver of Jury  Trial.  Each of the  parties  hereto  irrevocably
     waives any and all right to trial by jury with respect to any action, claim
     or other proceeding arising out of or relating to this Agreement.

          (i) Entire  Agreement.  This  Agreement  (including  all  exhibits and
     schedules hereto) contains the entire agreement and  understanding  between
     the parties  hereto in respect of Executive's  employment  and  supersedes,
     cancels and annuls any prior or contemporaneous written or oral agreements,
     understandings,   commitments   and  practices   between  them   respecting
     Executive's employment,  including all prior employment agreements, if any,
     between the Company and Executive, which agreement(s) hereby are terminated
     and shall be of no further force or effect.  Exempt from this are any prior
     stock options awarded to Executive.

          (j)  Amendment.  This Agreement may be amended only by a writing which
     makes express  reference to this Agreement as the subject of such amendment
     and which is signed by Executive and, on behalf of the Company, by its duly
     authorized officer.

          (k)  Severability.  If any term,  provision,  covenant or condition of
     this Agreement or part thereof,  or the application  thereof to any person,
     place or circumstance,  shall be held to be invalid,  unenforceable or void
     by a court of competent  jurisdiction,  the remainder of this Agreement and
     such term, provision,  covenant or condition shall remain in full force and
     effect,  and any  such  invalid,  unenforceable  or void  term,  provision,
     covenant or condition  shall be deemed,  without further action on the part
     of the parties hereto,  modified,  amended and limited, and the court shall
     have the power to modify,  to the extent  necessary  to render the same and
     the remainder of this  Agreement  valid,  enforceable  and lawful.  In this
     regard,  Executive  acknowledges that the provisions of Sections 5 and 6 of
     this  Agreement are  reasonable  and  necessary  for the  protection of the
     Company.

          (l)  Construction.  The headings and  captions of this  Agreement  are
     provided  for  convenience  only  and are  intended  to have no  effect  in
     construing or  interpreting  this  Agreement.  The language in all parts of
     this  Agreement  shall  be in all  cases  construed  according  to its fair
     meaning and not strictly for or against the Company or  Executive.  The use
     herein of the word  "including,"  when  following  any  general  provision,
     sentence,  clause,  statement,  term or  matter,  shall be  deemed  to mean
     "including,  without limitation." As used herein,  "Company" shall mean the
     Company and its subsidiaries and any purchaser of, successor to or assignee
     (whether  direct  or  indirect,  by  purchase,  merger,   consolidation  or
     otherwise) of all or substantially all of the Company's  business or assets
     which is obligated to perform this Agreement by operation of law, agreement
     pursuant to Section 7 of this Agreement or otherwise.  As used herein,  the
     words "day" or "days" shall mean a business day or days.

          (m)  Nonwaiver.  Neither  any  course of  dealing  nor any  failure or
     neglect of either party hereto in any instance to exercise any right, power
     or privilege  hereunder or under law shall constitute a waiver of any other
     right,  power or privilege or of the same right,  power or privilege in any
     other  instance.  All waivers by either party hereto must be contained in a
     written  instrument  signed by the party to be charged  and, in the case of
     the Company, by its duly authorized officer.

          (n) Remedies for Breach.  The parties  hereto agree that  Executive is
     obligated under this Agreement to render personal  services during the Term
     of a special,  unique,  unusual,  extraordinary and intellectual character,
     thereby giving this Agreement  special value, and, in the event of a breach
     or  threatened  breach of any covenant of Executive  herein,  the injury or

                                       60


     imminent  injury to the value and the  goodwill of the  Company's  business
     could not be reasonably or adequately  compensated  in damages in an action
     at law.  Accordingly,  Executive  expressly  acknowledges  that the Company
     shall be entitled to specific  performance,  injunctive relief or any other
     equitable remedy against  Executive,  without the posting of a bond, in the
     event of any breach or threatened breach of any provision of this Agreement
     by Executive  (including,  without  limitation,  Sections 5 and 6). Without
     limiting  the  generality  of  the  foregoing,  if  Executive  breaches  or
     threatens  to  breach  Section  5 or 6 of this  Agreement,  such  breach or
     threatened breach will entitle the Company,  without posting of bond, to an
     injunction  prohibiting  (i) Executive  from  disclosing  any  Confidential
     Information to any Competing  Business;  (ii) such Competing  Business from
     receiving from Executive or using any such  Confidential  Information;  and
     (iii) Executive from, indirectly or directly, owning, managing,  operating,
     joining,  controlling,  participating  in,  investing in or otherwise being
     connected or associated with, in any manner,  any such Competing  Business.
     The rights and remedies of the parties  hereto are cumulative and shall not
     be exclusive, and each such party shall be entitled to pursue all legal and
     equitable rights and remedies and to secure  performance of the obligations
     and duties of the other under this Agreement, and the enforcement of one or
     more of such rights and remedies by a party shall in no way  preclude  such
     party from pursuing,  at the same time or  subsequently,  any and all other
     rights and remedies available to it.

          (o)  Notices.  Any notice,  request,  consent or approval  required or
     permitted  to be given  under this  Agreement  or  pursuant to law shall be
     sufficient  if in writing,  and if and when sent by certified or registered
     mail,  return  receipt  requested,  with postage  prepaid,  to  Executive's
     residence (as reflected in the Company's records or as otherwise designated
     by Executive on twenty (20) days' prior  written  notice to the Company) or
     to the Company's principal executive office,  attention:  Chairman,  as the
     case may be. All such notices,  requests,  consents and approvals  shall be
     effective upon being deposited in the United States mail. However, the time
     period in which a response thereto must be given shall commence to run from
     the date of receipt on the return receipt of the notice,  request,  consent
     or approval by the addressee  thereof Rejection or other refusal to accept,
     or the inability to deliver  because of changed  address of which no notice
     was given as provided herein,  shall be deemed to be receipt of the notice,
     request, consent or approval sent.

          (p) Dispute Resolution - Arbitration  Policy. The Executive shall sign
     the Company's  Arbitration  Agreement,  which shall become Exhibit I to the
     Employment  Agreement.  Arbitration  will  provide a method to resolve  all
     disputes  between  the parties  other than those  expressly  exempted  from
     arbitration pursuant to the terms of Exhibit I and the Executive shall give
     up her rights to go to Court or an  administrative  agency to  resolve  any
     said  disputes.  Nothing  in  this  paragraph  8(p) or in  Exhibit  I shall
     preclude  either  party's right to seek  injunctive  relief to preserve the
     status  quo  or  prevent  irreparable  injury  during  the  pending  of the
     arbitration.

          (q)  Assistance  in  Proceedings,   Etc.   Executive  shall,   without
     additional  compensation,  during and after  expiration  of the Term,  upon
     reasonable  notice,  furnish such information and proper  assistance to the
     Company as may reasonably be required by the Company in connection with any
     legal  or  quasi-legal  proceeding,  including  any  external  or  internal
     investigation,  involving the Company or any of its  affiliates or in which
     any of them is, or may become, a party.

          (r) Survival.  Cessation or termination of Executive's employment with
     the  Company  shall  not  result  in  termination  of this  Agreement.  The
     respective obligations of Executive and rights and benefits afforded to the
     Company  as  provided  in  this  Agreement   shall  survive   cessation  or
     termination of Executive's employment hereunder.

                                       61


     IN WITNESS  WHEREOF,  the  Company  has caused  this  Agreement  to be duly
executed on its behalf by an officer thereunto duly authorized and Executive has
duly executed this Agreement, all as of the date and year first written above.

     Certain  statements  in  this  Annual  Report  on  Form  10-K  and  certain
statements made by the Company in other published documents (including,  without
limitation, press releases) are forward-looking.  These statements involve known
and unknown risks, uncertainties and other factors, including those discussed in
this  Exhibit  99.1  which  may  cause  our  actual   results,   performance  or
achievements to be materially different from any future results, performances or
achievements   expressed   or   implied  by  the   forward-looking   statements.
Forward-looking  statements  include,  but are not limited to, statements about:
regulatory  approval of our product  candidates,  market size for our  products,
timing of regulatory  approvals and commercial  introduction of our products and
potential   results  of  clinical  trials.  In  some  cases,  you  can  identify
forward-looking  statements by terms such as "may," "will,"  "should,"  "could,"
`would," "expects," "plans," "anticipates," "believes," "estimates," "projects,"
"predicts,"   "potential"   and   similar   expressions   intended  to  identify
forward--looking  statements.  The Company  cautions  stockholders and potential
investors that the following important factors, among others, in some cases have
affected, and in the future could affect, the Company's actual operating results
and could cause the actual results to differ  materially from those expressed in
any  forward-looking  statements  made by, or on behalf  of,  the  Company.  The
statements  under this  caption are intended to serve as  cautionary  statements
within the meaning of the Private Securities  Litigation Reform Act of 1995. The
Company undertake no obligation to publicly update or revise any forward-looking
statement,  whether as a result of new information,  future events or otherwise,
except as required  by law.  Forward  looking  statements  include,  but are not
limited to, statements about:

     o    the selection and licensing of therapeutic compounds;

     o    the ability to conduct clinical trials and obtain regulatory approval;

     o    anticipated business strategies;

     o    relationships  with collaborators and licensees and the benefits to be
          derived from those relationships;

     o    the impact of competitive products and pricing;

     o    competition and technological change;

     o    existing and future regulations affecting our business;

              Risks Relating to Our Business, Industry and Strategy

We have a history of operating losses and may never become profitable.

     We have received only limited  revenue from our imaging  products  CEA-Scan
and LeukoScan and have never received revenue from the  commercialization of any
of our therapeutic product candidates.  We have incurred  significant  operating
losses  since  our  formation  in 1982 and have not  earned a profit  since  our
inception. These operating losses and our failure to be profitable have been due
mainly  to the  significant  amount  of  money  that we spend  on  research  and
development. As of June 30, 2001, we had an accumulated deficit of approximately
$114.3  million.  We expect to continue  to  experience  operating  losses as we
attempt to develop and  commercialize  therapeutic  product  candidates.  We may
never have an approved or commercially  successful therapeutic product candidate
or any additional  imaging  products.  If we fail in our attempts to develop our
product  candidates  we may never  achieve  significant  revenues or  profitable
operations  and may not be able to earn  sufficient  revenues  to  continue as a
going concern.

Most of our therapeutic product candidates are at an early stage of development
and we may not be able to successfully develop and commercialize them.

     Most of our therapeutic  product candidates are still at the research stage
or early stages of pre-clinical and clinical  development.  Significant  further
research and development,  financial resources and personnel will be required to
develop commercially viable therapeutic products and obtain regulatory approval.
We may  not be able to  successfully  develop  and  commercialize  our  products
candidates,  only our diagnostic imaging products,  CEA-Scan and LeukoScan, have
been sold commercially;  we have never successfully commercialized a therapeutic
product candidate.  Much of our efforts and expenditures over the next few years
will be devoted to the development of our therapeutic product candidates.  If we
fail to gain approval from the FDA to  commercialize  our product  candidates we
may never generate significant revenues from product sales.

Our ability to market our products and product candidates depends upon obtaining
and   maintaining   regulatory   approval  which  is  subject  to  a  number  of
uncertainties.

     In order to obtain regulatory approval for the commercialization of each of
our product  candidates,  we will be required  to  complete  extensive  clinical
trials  in  humans  to  demonstrate  the  safety  and  efficacy  of the  product
candidates to the satisfaction of the United States Food and Drug Administration
(FDA) and applicable foreign regulatory  authorities.  This process is very time
consuming;  once we begin  clinical  trials for a new  diagnostic or therapeutic
product,  it may  take  five  to ten  years  or  more to  receive  the  required
regulatory  approval to commercialize that product and begin to market it to the
public.  The clinical trials  required for approval are a multi-step  process as
the product  candidate is tested in larger  populations and a product  candidate
could fail at any step.  Various federal and, in some cases,  state statutes and
regulations  also  govern or  influence  the  manufacturing,  safety,  labeling,
storage,  record keeping and marketing of these products. The lengthy process of
seeking these approvals,  and the subsequent compliance with applicable statutes
and regulations,  will require us to expend substantial resources.  In addition,
each stage of  clinical  development  is more costly than the prior stage and we
may expend substantial resources on a product candidate before we determine that
it cannot be successfully commercialized.

     A  clinical  trial may be  suspended  or  terminated  by us or the FDA,  or
otherwise fail, for a number of reasons, including:

                                       66



     o    the product  candidate  may cause  unforeseen  adverse side effects or
          have other  characteristics  that make it impossible or  impracticable
          for us to continue development or which may limit its commercial use;

     o    the results from  preclinical  studies and clinical  trials may not be
          predictive of results that will be obtained in later-stage testing;

     o    we may be unable to timely recruit a sufficient number of patients for
          our  clinical  trials  and delays in planned  patient  enrollment  may
          result in increased costs and delays;

     o    we may not be able to  supply  sufficient  quantities  of the  product
          candidate to complete the trial;

     o    the product candidate may not appear to be more effective than current
          available therapies; or

     o    the clinical investigators, trial monitors, or trial subjects may fail
          to comply with the trial plan or protocol.

     Any failure or substantial delay in successfully completing clinical trials
and  obtaining  regulatory  approval  for our product  candidates,  especially a
pivotal Phase III trial such as the trial for  Epratuzumab,  could severely harm
our business.  Approvals may not be granted on a timely basis,  if at all, or if
granted  may not cover all the  clinical  indications  for which we are  seeking
approval  or may  contain  significant  limitations  in the  form  of  warnings,
precautions or  contraindications  with respect to conditions of use. Even after
approval,  we may be  required  to recall or  withdraw  a product as a result of
subsequently   discovered  safety  or  efficacy  concerns  which  would  have  a
materially adverse effect on us.

If we are  unsuccessful  in  shifting  our  focus  from our  diagnostic  imaging
products to our antibody-based  therapeutic product candidates our business will
be materially and adversely affected.

     As we shift our focus from diagnostic  imaging to our  therapeutic  product
candidates  and  as our  scientific  efforts  lead  us in  new  directions  into
conditions  and  diseases  outside  of our area of  expertise,  we will  have to
develop internal expertise or form  collaborations in those areas. If we proceed
independently  we will  require  additional  resources  that may be difficult to
obtain. As a result, we may have to enter into  collaboration  arrangements with
others that may  require us to  relinquish  rights to some of our  technologies,
products or product candidates that we would otherwise pursue independently.  We
may be unable to acquire the necessary expertise or enter into collaborations on
acceptable  terms  which  would  hinder  us in  our  development  of  additional
therapeutic product candidates.

We may not be able to successfully  develop a market for our products or product
candidates.

     We have never developed and commercialized a therapeutic product candidate.
Our diagnostic imaging products,  CEA-Scan and LeukoScan,  are the only products
which we are licensed to market and sell. To date, we have a limited  market for
these  products and have received  only limited  revenues from the sale of these
products.  We are still  developing a market for these products and have not yet
begun to develop a market for our therapeutic product candidates.  We may not be
able to achieve market  acceptance of our current products or any of our product
candidates which would have a significant impact on our revenues.

                                       67


Our relationship with Amgen may not be successful.

     We have licensed Epratuzumab to Amgen in North America and Australia. Under
our licensing  agreement,  Amgen has undertaken the final clinical  development,
commercialization  and  manufacture  of Epratuzumab  for these  markets.  We are
dependent on Amgen for the successful  commercialization of Epratuzumab in these
markets.  If  Amgen  does not  fully  perform  its  responsibilities  under  our
agreement, or if the ongoing Phase III trial is not successful,  the development
of this product candidate could be substantially delayed in these major markets.
In addition, the agreement provides for certain milestone payments to be made to
us upon Amgen's  achievement of various clinical and net sales targets. If Amgen
does not diligently pursue  development of Epratuzumab,  or if the ongoing Phase
III trial is not successful,  we may never receive any milestone  payments under
this  agreement  which  would  seriously  reduce  our  financial  resources  and
adversely  affect our ability to fund the development and testing of our product
candidates.

We currently  receive  revenues from a limited  number of sources;  if we do not
receive these revenues we may need to find alternative sources of funding.

     To  date,  we  have  received  revenues  from  (i) the  sale of our  equity
securities,  (ii)  payments  from  Amgen  under our  Development  and  Licensing
Agreement,  (iii) product sales of CEA-Scan and LeukoScan, (iv) one-time signing
fees or grants from  corporate  partners or government  grants under  agreements
that  support the  development  of our product  candidates,  and (v)  investment
income.  We may not  continue to receive  these  revenues or the amount of these
revenues may be dramatically  reduced. In the absence of these revenues, we will
have to obtain other  sources of funding to continue to conduct our research and
development activities.

We may be unable to obtain the additional capital needed to operate and grow our
business.

     We are expending resources on our research and development efforts. We will
need  addition  capital  in  order  to  commercialize  any  therapeutic  product
candidates  that we  identify.  When our needs  for cash  deplete  our  existing
capital  position,  we will be required to  significantly  reduce our  operating
expenses, which could have a significant and adverse effect on us.

Our capital requirements depend on numerous factors, including:

     o    the progress of our research and development programs;

     o    the progress of pre-clinical and clinical testing;

     o    the time and costs involved in obtaining regulatory approvals;

     o    the cost of filing,  prosecuting,  defending  and enforcing any patent
          claims and other intellectual property rights;

     o    competing technological and market developments;

                                       68


     o    our  ability  to  establish  collaborative   arrangements  with  large
          pharmaceutical companies and others; and

     o    the  requirements  and timing of entering  into  technology  licensing
          agreements and other similar arrangements.

     We may use our existing resources before we may otherwise expect because of
changes in our research and development and  commercialization  plans or because
of other  factors  affecting  our  operating  expenses or capital  expenditures,
including potential acquisitions of other businesses, assets or technologies.

     Our  ability  to raise  future  capital  on  acceptable  terms  depends  on
conditions in the public and private equity markets and our performance, as well
as the overall  performance  of other  companies  in the  biopharmaceutical  and
biotechnology sectors. Additional financing may not be available to us at all or
on terms we find  acceptable.  Furthermore,  any financing that we do obtain may
cause substantial dilution to our existing stockholders.

If we cannot successfully  manufacture our products and product candidates in an
efficient  manner,  our  ability to sell our  products  and to conduct  clinical
trials and commercialize our product candidates would be impaired.

     Our  ability to supply the demand for our  products  and to conduct  timely
preclinical and clinical research and development programs and commercialize our
product  candidates  depends,  in part,  upon our  ability  to  manufacture  our
products and product  candidates,  either directly or through third parties,  in
accordance  with FDA and other  regulatory  requirements.  We may not be able to
manufacture   our  products  or  product   candidates  in  a   reproducible   or
cost-effective  manner at our  facilities in the quantities and with the quality
that we require.  We may also have difficulties  obtaining the raw materials and
supplies necessary to the manufacturing  process. In addition, if several of our
product  candidates  are approved for  marketing and sale, we may not be able to
manufacture  commercial  quantities of multiple  products  successfully  or with
acceptable profit margins.

     We have  begun to scale up our  manufacturing  facilities  for our  product
candidates to supply clinical trials and possible  commercial  demand. If we are
unable to use our own manufacturing facilities or to contract with a third-party
to manufacture our products  candidates on acceptable  terms, we may not be able
to conduct  preclinical and clinical testing or to supply commercial  quantities
of our product candidates.

     In addition,  if our  manufacturing  facilities fail to comply with FDA and
other  regulatory  requirements,  we will be required to suspend  manufacturing.
This will have a material adverse effect on our financial condition,  results of
operations, and cash flow.

Our collaboration efforts and agreements may fail or be terminated, resulting in
significant  delays  and  substantial  increases  in the  cost of the  research,
development and commercialization of some of our product candidates.

     We are party to various  arrangements with academic and corporate  partners
and others. The successful development and manufacture of the product candidates
covered by these  arrangements  depends upon outside  parties' fully  performing
their  contractual  responsibilities.  If any of the other  parties  breaches or
terminates its agreement with us or otherwise fails to conduct its activities in
a timely manner, the development or  commercialization of that product candidate
or research program may be delayed.

                                       69


     For example,  the Center for Molecular Medicine and Immunology or "CMMI", a
not-for-profit  cancer research center,  of which Dr. David M.  Goldenberg,  our
Chairman and Chief Scientific Officer is the founder,  President and a member of
the Board of Trustees,  performs contracted pre-clinical  evaluations in product
areas of  importance  to us. CMMI also  conducts  basic  research in a number of
areas of  potential  interest  to us. If CMMI were no  longer to  provide  these
services,  we would have to make  alternative  arrangements  with third parties,
which  could   significantly   delay  and  increase  expenses   associated  with
development and commercialization of our product candidates.

     Dependence  upon third parties for the  manufacture of some of our products
candidates  may adversely  affect our profit  margins and our ability to develop
and deliver  products on a timely and  competitive  basis.  For  example,  if we
contract  with a third  party for the  development  and  production  of  certain
humanized   antibodies  and  this  party  does  not  perform  according  to  our
expectations,  our ability to develop and commercialize those product candidates
will be adversely  affected.  In addition,  we rely on a single third party,  SP
Pharmaceuticals,  to perform  certain  end-stage  portions of the  manufacturing
process  for  CEA-Scan  and  LeukoScan,  which we do not have the  resources  to
perform. If SP Pharmaceuticals were to become unavailable, we would be unable to
complete the  manufacturing  process  until we entered  into an  agreement  with
another  qualified entity,  which could cause substantial  delays and materially
adversely affect our operations.

     We also are considering  additional  collaboration and other agreements for
various product  candidates.  We may not be able to negotiate these arrangements
on favorable terms or at all and these relationships may not be successful.

We may not be able to obtain and adequately  protect our  intellectual  property
rights or avoid infringing the rights of others.

     Our  commercial   success  is  highly   dependent  upon  our  own  and  our
collaborators' ability to obtain and defend patent rights and other intellectual
property  rights  that are  important  to the  commercialization  of our product
candidates.  We or our collaborators have filed patent  applications on products
and processes relating to our diagnostic imaging products and our antibody-based
therapeutic product candidates,  as well as other technologies and inventions in
the United States and in certain foreign countries.  Although we have obtained a
number of U.S.  patents,  patent  applications  owned or  licensed by us may not
result in  patents  being  issued.  Moreover,  these  patents  may not afford us
protection against competitors with similar technology or products.

     Although we are not aware of any such  conflict,  parts of our  technology,
techniques, and product candidates may conflict with patents owned by or granted
to others.  Any patent  holders  could sue us for damages and seek to prevent us
from selling or developing our products or product  candidates.  Since we do not
have the resources to maintain a staff whose primary  function is to investigate
the level of  protection  afforded to third  parties on devices  and  components
which we use in our products and product candidates, it is possible that a third
party could  successfully claim that our products infringe on their intellectual
property rights.

                                       70


     Uncertainties  resulting  from the litigation  and  continuation  of patent
litigation  or other  proceedings  could have a material  adverse  effect on our
ability to compete in the marketplace. Any patent litigation or other proceeding
even if resolved  in our favor,  absorbs  significant  financial  resources  and
management time. Some of our competitors may be able to sustain these costs more
effectively  than we can because of their  substantially  greater  financial and
managerial  resources.  If a patent  litigation or other  intellectual  property
proceeding is resolved  unfavorably to us, we may be enjoined from manufacturing
or selling our products and services  without a license from the other party and
be held  liable  for  significant  damages.  We may not be  able to  obtain  any
required license on commercially acceptable terms, if at all.

Our operations could suffer if we are  unsuccessful in our pending  infringement
claims concerning our CEA antibodies.

     We are  involved in certain  litigation  with F.  Hoffmann-LaRoche  and its
affiliates concerning the validity of our European patents covering the antibody
we use in our CEA-Scan  cancer imaging  product and our CEA-Cide  cancer therapy
product,  as well as the use of highly specific anti-CEA antibodies for a number
of other uses. We have claimed that they have infringed our patent and they have
counterclaimed seeking to nullify the patents that were issued. If we receive an
unfavorable outcome in any of these matters, our business could be significantly
and adversely affected.

If we are not able to keep our trade secrets  confidential,  our  technology and
information may be used by others to compete against us.

     In  addition  to our  reliance  on  patents,  we  attempt  to  protect  our
proprietary   products   and   processes   by  relying  on  trade  secret  laws,
nondisclosure   and   confidentiality   agreements,   and  exclusive   licensing
arrangements with our employees and certain other persons who have access to our
proprietary  products or  processes or have  licensing or research  arrangements
exclusive to us. These  agreements or  arrangements  may not provide  meaningful
protection  for  our  proprietary   products  and  processes  in  the  event  of
unauthorized  use or disclosure of such  information.  Others may  independently
develop  substantially  equivalent  proprietary  information  and  techniques or
otherwise gain access to our trade secrets or technology  which will  materially
and adversely affect our competitive position.

We face substantial  competition in the biotechnology  field and may not be able
to successfully compete.

     The biotechnology industry is highly competitive,  particularly in the area
of cancer  diagnostic  and  therapeutic  products.  There is the  potential  for
extensive  technological  innovations  in  relatively  short periods of time and
rapid  technological  change or developments by others may result in our current
products as well as those in development becoming noncompetitive or obsolete. We
are likely to  encounter  significant  competition  with respect to our existing
products  as well as our  products  currently  under  development.  A number  of
companies,  including IDEC Pharmaceuticals,  Genentech, Glaxo SmithKline, Ligand
Pharmaceuticals,  Millennium  Pharmaceuticals,  Nycomed Amersham, Protein Design
Laboratories,  Schering  AG,  and  Corixa  Pharmaceuticals,  are  engaged in the
biotechnology  field, and in particular the development of cancer diagnostic and
therapeutic  products.  Many  of  these  companies  have  significantly  greater
financial,  technical and marketing  resources than we do. In addition,  many of
these  companies  may have  more  established  positions  in the  pharmaceutical
industry and may be better equipped than us to develop,  refine and market their
products.  Our smaller  competitors  may also obtain a  significant  competitive
advantage if they acquire or discover patentable inventions,  form collaborative
arrangements or merge with large pharmaceutical companies.

                                       71


     We also expect to face increasing  competition from  universities and other
non-profit  research  organizations.  These institutions carry out a significant
amount of research and  development in the field of  antibody-based  technology.
These  institutions are becoming  increasingly  aware of the commercial value of
their findings and more active in seeking patent and other  proprietary  rights,
as well as licensing revenues.

     If a competitor  announces a successful  clinical study or an approval by a
regulatory  agency to market a product that is  comparable to one of our product
candidates,  such  announcement  may  have  a  material  adverse  effect  on our
operations, future prospects and the price of our common stock.

Our limited  marketing  and sales  experience  and  capability  could impact our
ability to successfully sell our current products and our product candidates.

     We are relying, in substantial part, on our own limited sales and marketing
organization to market our current imaging products  CEA-Scan and LeukoScan.  We
have no internal  marketing or  distribution  experience for our  antibody-based
therapeutic product candidates.  Any sales effort we undertake may be costly and
may not be  successful.  If we are unable to maintain  and continue to build our
current sales force or develop a marketing group for our product candidates, our
financial  condition and operating  results may be  significantly  and adversely
affected.

Our limited  manufacturing  experience  and  capacity,  which is restricted to a
single site and  facility,  could  impact our ability to make our  products  for
clinical testing and commercialization.

     We rely on our current  manufacturing  facilities in our headquarters,  and
the staff working there,  for all product  supplies  needed for research and for
future commercial  supplies.  Any interruption in work at this site,  whether by
natural acts or other  causes,  would  significantly  and  adversely  affect our
operations,  and  product-development  and research programs.  The same facility
houses  all  of  our  other  departments,  including  clinical,  regulatory  and
financial  records.  Although  we  attempt to protect  records  and  proprietary
reagents,  any interruption in operations at our headquarters  would have a very
adverse  impact on us and our programs and plans.  Further,  since we have never
manufactured a commercial  therapeutic  product,  we are at risk of possibly not
having as much  experience  as others in the  industry  may have for this  task.
However,  we believe that our  experience  and success in achieving  economical,
large-scale  production of our  antibody-based  imaging products is pertinent to
this effort.

We could be temporarily  unable to sell our products if our agreements  with our
distributors were terminated.

     We currently do not have the resources to  internally  develop and maintain
the operating  procedures  required by the FDA and comparable foreign regulatory
authorities  to  oversee  distribution  of our  products.  As a result,  we have
entered into  arrangements  with third  parties to perform this function for the
foreseeable  future. If these agreements are terminated,  we will be required to
enter into arrangements with other government approved third parties in order to
be  able to  distribute  our  products  and we will be  unable  to  continue  to
distribute  our products until an acceptable  alternative  is identified.  If we
were even only temporarily unable to distribute our products, our business could
be significantly and adversely effected.

                                       72


     Currently,  Eli Lilly  Deutschland GmbH ("Lilly")  packages and distributes
LeukoScan and CEA-Scan  within the countries  comprising  the European Union and
certain other countries  subject to the receipt of regulatory  approval pursuant
to a  Distribution  Agreement  with us. Lilly has notified us that it intends to
terminate this  agreement as of the end of the current  calendar year. We expect
to  establish  alternate  distribution  arrangements  by that time,  although we
cannot provide you with assurance that we will be successful.

We may not receive approval to sell LeukoScan in the United States.

     We have not yet received approval from the FDA to market and sell LeukoScan
in the United States and cannot predict when we will obtain  approval,  if ever.
In  addition,  the FDA could  impose  conditions  on its  approval,  which could
significantly affect the commercial viability of the product or could require us
to  undertake  significant  additional  studies or otherwise  expend  additional
significant funds. If we do not receive approval to market and sell LeukoScan in
the  United  States  in the  near  future  or if  the  FDA  imposes  significant
conditions or  restrictions,  our business and operations could be significantly
and adversely affected.

We may be unable to continue to use mouse fluids for future products which could
require us to make  expensive  and time  consuming  changes to our  products  in
development.

     CEA-Scan and certain of our other  imaging  agents are derived from ascites
fluid produced in mice.  Regulatory  authorities,  particularly in Europe,  have
expressed  concerns  about  the  use of  mouse  fluids  for  the  production  of
monoclonal antibodies. The regulatory authorities may not agree that our quality
control procedures for future products are adequate. While we are continuing our
development  efforts to produce certain of our monoclonal  antibodies using cell
culture methods, this process constitutes a substantial production change, which
will require additional  manufacturing equipment and new regulatory approval. We
may not have the resources to acquire the additional manufacturing equipment and
expertise  and we cannot be sure that we will  receive the  required  regulatory
approval on a timely basis, if at all.

We may be liable for  contamination or other harm caused by hazardous  materials
that we use.

     In  addition  to laws and  regulations  enforced  by the  FDA,  we are also
subject to regulation under various other foreign,  federal, state or local laws
and  regulations.  Our research and  development  involve the  controlled use of
hazardous materials,  chemicals,  viruses and various radioactive compounds. The
risk of  accidental  contamination  or injury  from  these  materials  cannot be
completely  eliminated.  If an accident occurs,  we could be held liable for any
damages that result and any liability could exceed our resources.

We could be exposed to significant  liability claims and our insurance  coverage
may not be adequate to cover these claims.

     The  testing,   marketing  and  manufacturing  of  our  product  candidates
necessarily involve the risk of product liability.  Their use in clinical trials
and their sale may expose us to substantial liability claims. These claims might
be made directly by patients,  consumers,  pharmaceutical  companies,  or others
selling the products.  While we currently have product liability  insurance that
we consider adequate for our business, we may not be able to obtain insurance in
the future at an acceptable  cost, if at all. If we cannot maintain our existing
or comparable liability insurance, our ability to clinically test and market our
products may be significantly  impaired.  Moreover,  the amount and scope of our
insurance coverage or indemnification arrangements with any distributor or other
third party upon which we rely may be inadequate to protect us in the event of a
successful  product  liability  claim.  Any claim in excess of the amount of any
insurance could  significantly and adversely affect our financial  condition and
operating results.

                                       73


Certain potential conflicts of interest exist which could affect our operations.

     Members of our  management and Board of Directors  have  relationships  and
agreements  with related  parties that create  conflicts of interest  that could
adversely affect our business.

     For example,  Dr. David M.  Goldenberg,  our Chairman and Chief  Scientific
Officer,  is the  founder,  President  and a member of the Board of  Trustees of
CMMI, a not-for-profit  cancer research center.  Dr. Goldenberg  devotes more of
his time to working for CMMI than for us and other key personnel  currently have
responsibilities both to CMMI and us. As a result, the potential for conflict of
interest  exists and  disputes  could  arise  over the  allocation  of  research
projects and ownership of intellectual property rights.

The loss of key employees could adversely affect our operations.

     We are heavily dependent upon the talents of Dr. Goldenberg and certain key
scientific personnel.  If Dr. Goldenberg or any of our other key personnel leave
our employ,  our operations could be significantly  and adversely  affected.  In
addition,  from  time  to  time we have a need  to  expand  our  management  and
scientific  personnel.  Competition for qualified personnel in the biotechnology
and  pharmaceutical  industries  is intense and we may not be  successful in our
recruitment  efforts.  If we are  unable  to retain  or,  when  needed,  attract
additional qualified  personnel,  our operations also could be significantly and
adversely affected.

We  have  agreed  to  certain  covenants  in  our  1999  financing  which  place
restrictions on the operation of our business.

     In  connection  with our  December  1999  financing,  we agreed to  certain
covenants,  including covenants that will apply until such time as the investors
in that  offering  and  their  affiliates  beneficially  own less than 5% of our
common stock.  Among other  things,  we agreed that without the prior consent of
the  investors,  we may not sell our  business to anyone that is an affiliate of
ours, unless the sale is for consideration at least equal to (a) the fair market
value in the event of a sale of assets (as determined in good faith by our board
of  directors)  or (b) the then  current  market price in the event of a sale of
stock. As of June 30, 2001, such investors in the aggregate  beneficially  owned
5.7% of the Company's outstanding common stock.

Revenues  from our  products  depend in part on  reimbursement  from health care
payors, which is uncertain.

     The  continuing  efforts of  government  and  insurance  companies,  health
maintenance  organizations  and other  payors of health care costs to contain or
reduce costs of health care may affect our future  revenues  and  profitability.
Our ability to commercialize  our products  successfully  will depend in part on
the extent to which  private  health  insurers,  organizations  such as HMOs and
governmental  authorities can obtain  appropriate  reimbursement  levels for the
cost of our products and related treatment.  Third-party payors are increasingly
challenging  the prices  charged for medical  products and services.  Also,  the
trend toward managed health care in the United States and the concurrent  growth
of organizations  such as HMOs,  which could control or significantly  influence
the  purchase of health  care  services  and  products,  as well as  legislative
proposals to reform health care or reduce government insurance programs, may all
result in lower prices for or rejection of our  products.  The cost  containment
measures that health care payors and providers are instituting and the effect of
any health care reform  could  materially  and  adversely  affect our ability to
operate profitably.  Furthermore,  even if reimbursement is available, we cannot
be sure that it will be  available  at price  levels  sufficient  to  realize an
appropriate return on our investment in product candidates.

                                       74


Disruption  in New  York  City  and the  U.S.  commercial  activities  generally
following the September 2001 terrorist  attacks in the U.S. may adversely impact
our results of operations, our ability to raise capital or our future growth.

     The operations of our facilities have been and may continue to be harmed by
the recent terrorist  attacks on the U.S. For example,  we may experience a rise
in  operating  costs,  such  as  costs  for  transportation,  courier  services,
insurance and security. We also may experience delays in receiving payments from
payors that have been affected by the attacks,  which,  in turn,  would harm our
cash  flow.  The U.S.  economy  in  general  may be  adversely  affected  by the
terrorist  attacks or by any related outbreak of hostilities.  Any such economic
downturn could adversely impact our results of operations, impair our ability to
raise capital or impede our ability to continue growing our business.


                        Risks Related to Our Common Stock

The market price of our stock may fluctuate based on factors beyond our control.

     The  market  price of our stock has been and is  likely to  continue  to be
highly  volatile.  Furthermore,  the stock market  generally  and the market for
stocks   of   companies   with   lower   market    capitalizations   and   small
biopharmaceutical  companies,  like us, have from time to time  experienced  and
likely will again experience  significant price and volume fluctuations that are
unrelated to the operating performance of a particular company.

     From time to time,  stock market  professionals  publish  research  reports
covering  our  business  and our  future  prospects.  As a result of a number of
factors,  we may be unable to meet the  expectations  of securities  analysts or
investors and our stock price may decline. These factors include:

     o    announcements   by  us  or  our   competitors  of  clinical   results,
          technological  innovations,  product  sales,  new  products or product
          candidates;

     o    the  formation  or   termination   of  our  corporate   alliances  and
          distribution arrangements;

     o    developments or disputes concerning patent or proprietary rights;

     o    government regulatory action;

     o    period-to-period fluctuations in the results of our operations; and

     o    developments  and market  conditions for emerging growth companies and
          biopharmaceutical companies, in general.

         In the past, following periods of volatility in the market prices of
the securities of companies in our industry, securities class action litigation
has often been instituted against those companies. If we face such litigation in
the future, it would result in substantial costs and a diversion of management's
attention and resources, which would negatively impact our business.

                                       75


Our principal  stockholder can influence most matters requiring  approval by our
stockholders.

     As of June 30, 2001,  Dr.  Goldenberg,  our  Chairman and Chief  Scientific
Officer,  controlled  the right to vote over  approximately  17.6% of our common
stock. As a result of this voting power, Dr.  Goldenberg may have the ability to
determine the election of all of our directors,  direct our policies and control
the  outcome  of  substantially  all  matters  which may be put to a vote of our
stockholders.

Resales of shares held by our  directors  and  executive  officers may lower the
market price of our common stock and impair our ability to raise new funds.

     As of June 30, 2001,  we had a total of  49,533,871  shares of common stock
outstanding,  8,088,269  of  which  were  held by our  directors  and  executive
officers.  These shares may be resold within the limitations imposed by Rule 144
under the Securities  Act.  Sales of  substantial  amounts of shares or the mere
prospect  that those sales will occur could cause the market price of our common
stock to decline. Those sales might make it more difficult for us to sell equity
and equity-related securities in the future at a time and price that we consider
appropriate.

We have  adopted  anti-takeover  provisions  that may  frustrate  any attempt to
acquire our company or to remove or replace our management.

     Provisions of our  certificate of  incorporation,  our by-laws and Delaware
law could make it more  difficult  for a third  party to acquire  control of our
company in a transaction not approved by our board of directors.

     Our Board of Directors  may issue up to 10 million  shares of our preferred
stock  and  may  determine  the  price,  rights,  preferences,   privileges  and
restrictions,  including  voting  and  conversion  rights,  of these  shares  of
preferred stock.  These  determinations  may be made without any further vote or
action by our  stockholders.  The  issuance  of  preferred  stock could have the
effect of delaying,  deterring or preventing a change in control of our company,
or could impose  various  procedural and other  requirements  that could make it
more  difficult  for  holders of our common  stock to effect  certain  corporate
actions,  including the replacement of incumbent directors and the completion of
transactions  opposed by the  incumbent  board of  directors.  The rights of the
holders of our common stock would be subject to, and may be  adversely  affected
by, the rights of the holders of any  preferred  stock that may be issued in the
future.  We have no present  plans to issue any shares of  preferred  stock.  In
addition,  we have  adopted  a  stockholder  rights  plan  which  makes  it more
difficult  for a third  party to acquire  control  of our  company  without  the
support of our board of directors.

     We are also subject to Section 203 of the Delaware General Corporation Law,
which prohibits us from engaging in a business  combination  with any interested
stockholder  for a period  of three  years  from the date the  person  became an
interested stockholder, unless certain conditions are met.
