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 LymphoCide'TM' (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  which targets the CD22 receptor of
B-cells and B-cell lymphomas. The Company has now advanced the humanized form of
epratuzumab  to Phase III  clinical  testing,  evaluating  the agent in  certain
indolent  non-Hodgkin's  lymphoma  patients.  The Company is  preparing a second
Phase III clinical  trial to evaluate  epratuzumab  in patients  with a specific
type of aggressive lymphoma.  The Company also is conducting 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 Company also is evaluating the humanized  antibody
as a yttrium-90 labeled therapeutic  product,  and has discontinued all clinical
trials with the murine  form (see "In Vivo  Therapeutic  Products").  A Phase II
clinical  trial is being  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/II  clinical  trial  in
colorectal  and  breast  cancer  patients,   and  as  a  labeled  antibody  with
yttrium-90,  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 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  total  patient
management.  On June 28,  1996,  the FDA  licensed  CEA-Scan  for use with other
standard diagnostic  modalities for the detection of recurrent and/or metastatic
colorectal  cancer.  On October 4,  1996,  the  Company  was  granted  marketing
authorization by the European Commission for use of CEA-Scan in the 15 countries
comprising the European Union for the same  indication as approved in the United
States.  On September 16, 1997, the Company received a notice of compliance from
the Health  Protection  Branch  permitting  it to market  CEA-Scan in Canada for
recurrent and metastatic colorectal cancer.

     On February 14, 1997,  the Company was granted  regulatory  approval by the
European  Commission  to  market  LeukoScan'r',  an in vivo  infectious  disease
diagnostic  imaging  product,  in all 15  countries  which  are  members  of the
European  Union,  for  the  detection  and  diagnosis  of  osteomyelitis   (bone
infection)  in long bones and in diabetic foot ulcer  patients.  On December 19,
1996, the Company filed a Biologics  License  Application  ("BLA") for LeukoScan
with the FDA for

                                       1
<PAGE>

the same indication  approved in Europe,  plus an additional  indication for the
diagnosis of acute, atypical  appendicitis.  A New Drug Submission for LeukoScan
for the same  indications  as in the U.S.  was  filed  with the HPB in Canada on
March 24,  1998.  The Company  also has decided  not to  continue  pursuing  the
broadening  of its  approval  for  LeukoScan  in Europe to  include  the  acute,
atypical  appendicitis  indication,  but has  instead  published  its  Phase III
efficacy data.

     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,  currently in 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").

     The  Company  has been  directly  responsible  for sales and  marketing  of
CEA-Scan worldwide and has employed its own sales and marketing organizations in
the U.S. and Europe and  negotiated  local  distribution  agreements  in certain
markets  outside the U.S.  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.  (see  "Marketing,
Sales  and  Distribution"  for the  current  status  of  these  agreements).  On
September 9, 1998,  the Company  announced that Syncor  International  agreed to
make  CEA-Scan  available to its hospital  and clinic  accounts  across the U.S.
supported  by  Immunomedics'  technical  support  specialists.  The  Company has
entered into an agreement  with the ICS  Division of Bergen  Brunswig  Specialty
Corporation  to  provide  product  support  services  in  the  U.S.,   including
distribution,  order  management  and  customer  service for  CEA-Scan and other
products from time to time.

     The  Company  has  entered  into a  Distribution  Agreement  with Eli Lilly
Deutschland  GmbH  ("Lilly")  pursuant to which Lilly  packages and  distributes
CEA-Scan and LeukoScan  within the countries  comprising  the European Union and
certain other countries subject to receipt of certain regulatory approvals.

     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.  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") which establishes the rights
and obligations of the respective members. Under the

                                       2
<PAGE>

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 which establishes their relative rights
and obligations.

     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  coordinate  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  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,  LymphoCide  (epratuzumab)at  the  University of
Nebraska.  This product consisted of 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.  The  Company  has also  tested the  unlabeled  (cold) form of
epratuzumab  in a Phase I/II trial of about 100 patients  with both indolent and
aggressive  forms  of  NHL,  and has  found  the  agent  to  show  good  safety,
tolerability, and evidence of 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  has been  reached by the Company and FDA. The
Phase III clinical trial will be conducted in approximately  thirty sites in the
U.S. and Europe.  The Company is preparing for a second Phase III clinical trial
to  evaluate  epratuzumab  in  patients  with  a  specific  type  of  aggressive
non-Hodgkin's  lymphoma.  The  Company  has begun a Phase II  clinical  trial to
evaluate the safety and efficacy of  epratuzumab,  in  combination  with Rituxan
(rituxamab),  in both indolent and aggressive NHL patients. The product is being
evaluated as an unlabeled  antibody.  The initial  studies of the  unlabeled and
labeled forms of epratuzumab  have indicated that both forms of the product show
clinical responses (partial or complete  remissions),  even when patients failed
chemotherapy or prior antibody therapy.

                                       3
<PAGE>

     In February  1999,  the Company  entered  into a  Cooperative  Research and
Development  Agreement  ("CRADA")  with the National  Cancer  Institute  ("NCI")
covering the development anduse of its humanized lymphoma antibody conjugated to
recombinant  ribonucleases  (RNase) as a potential  new  anticancer  agent.  The
Company  contributed its humanized lymphoma antibody and the NCI contributed the
RNase. 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.  The Company  provides
epratuzumab  to  DCTD  for  evaluation   under  mutually  agreed  upon  clinical
protocol(s).

     A Phase II clinical trial has been completed with the Company's  colorectal
cancer therapeutic, CEA-Cide(labetuzumab). This trial was conducted in Europe in
patients with metastatic colorectal cancer who failed chemotherapy.  The Company
has begun 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 the product 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").

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.

     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

                                       4
<PAGE>

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,  this product  also was approved by the European  Commission
for the same indication. On September 16, 1997, the Company received a notice of
compliance from the HPB permitting it to market CEA-Scan in Canada  forrecurrent
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).

     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. The Company also is
performing Phase III clinical trials,  using CEA-Scan,  for imaging lung cancer.
In  addition,  Phase II  clinical  trials for breast  cancer  imaging  have been
completed,  results  of which  have been  published  in the July  2000  issue of
Cancer.

     LeukoScan  (sulesomab) is a monoclonal  antibody fragment,  which 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 BLA with the FDA,
seeking  approval  to  market  LeukoScan  in the U.S.  for the  same  indication
approved  in Europe,  plus an  additional  indication  for  diagnosis  of acute,
atypical appendicitis.  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).

     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 are underway).

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

Research Programs

     The Company incurred approximately $8,670,000, $10,100,000 and $11,738,000,
in total research and development expense during its fiscal years ended June 30,
2000, 1999 and 1998, 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 very good  uptake in the  patients'  tumors.  The  Company is now
focusing  on the  study  of  these  humanized  monoclonal  antibodies  unlabeled
(non-isotopic) and labeled with a pure  beta-emitting  isotope,  yttrium-90,  in
patients with the appropriate target tumors (discussed below).

Alternative Radioisotopes

     The Company has used iodine-131 to label its anti-lymphoma  antibody (LL2),
which has been  evaluated  in a phase I  clinical  trial  against  non-Hodgkin's
lymphoma.   This  disease  has   previously   been  found  to  respond  well  to
radioimmunotherapy   using   iodine-131-labeled,    murine-based   anti-lymphoma
antibodies by  investigators  at several  institutions.  However,  one potential
drawback of an  iodine-131-labeled  LL2  antibody is the finding  that LL2, as a
rapidly internalizing antibody, is readily metabolized with the iodine-131-bound
metabolite  and is quickly  excreted from the target cell.  This means that full
advantage  is  not  taken  of  the   eight-day   half-life  of  the   iodine-131
radionuclide,  in this one  particular  disease.  In contrast,  yttrium-90  from
administered  yttrium-90-labeled  LL2  has  been  shown  to be  retained  inside
lymphoma cells for long periods after antibody metabolism.  For this reason, and
also for reasons of greater efficacy against larger tumors and the potential for
outpatient use due to lack of any associated gamma-ray emissions,  the Company's
scientists have developed  yttrium-90-LL2 as a  second-generation  product.  The
Company has developed a proprietary technology using a compound called "DOTA" to
tightly  bind  yttrium-90  to  antibodies,  assuring  that the isotope will stay
attached during circulation, and thus minimally impact the bone marrow and other
organ  systems.  The labeling  procedure has been  developed by the Company as a
15-minute,  simple labeling method  resulting in over 90%  incorporation  of the
yttrium onto the antibody. The Company has begun Phase I/II clinical trials with
yttrium-90-labeled   humanized   antibodies.   The   Company  is  not  alone  in
substituting   yttrium-90  for  iodine-131  as  an  antibody-delivered   isotope
therapeutic.  At least  one  other  competitor  is  labeling  an  antibody  with
yttrium-90 for similar indications.

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

                                       6
<PAGE>

site and in a manner that is known not to interfere  with antigen  binding.  The
Company also is continuing to investigate  "pre-targeting",  whereby an antibody
is   administered   first  and  then   followed   by  a  separate   radionuclide
administration.  Secondary recognition groups are attached, one to the targeting
antibody and the other to the  radionuclide  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.

Peptides

     During fiscal year 2000, 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, which can be radiolabeled with indium-111 and yttrium-90.

Intraoperative Cancer Detection

     The   Company  has  been   developing   intraoperative   cancer   detection
applications with CEA-Scan, utilizing hand-held, radiation-detecting probes. The
Company has learned that surgeons have  successfully  used CEA-Scan in this way,
within 48 hours of its injection and external imaging.  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.  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
allowing for improved  intraoperative,  intravascular and endoscopic  detection.
The Company has  discussed  with the FDA the use of CEA-Scan  with gamma probes,
and plans to conduct  clinical  trials along lines proposed by the FDA, with the
objectives of gaining  regulatory  approval for this new  intraoperative  use of
CEA-Scan.

Government Grants

     The Company has begun work in  September  2000 on a new 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  drastically  improved  therapeutic  ratios (the amount of radiation
deposited  in a tumor  versus  the  amount  deposited  in normal  tissues).  The
injected radioactivity either binds to

                                       7
<PAGE>

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 entering 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 will be completed during calendar year 2001, and may result
in an advanced radioimmunotherapy agent for the treatment of breast cancer.

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 patient  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 and Chief
Executive Officer of the Company, is the founder, current President and a member
of the  Board of  Trustees  of CMMI.  Dr.  Goldenberg  devotes  more of his time
working for CMMI than for the Company.  Certain  consultants to the Company have
employment  relationships  with CMMI,  and 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 2000, 1999 and 1998.

     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  $128,000,  $45,000 and $98,000  during the years ended
June 30, 2000,  1999 and 1998,  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 1999 and 1998,  the Board of  Directors of
the  Company  authorized  grants to CMMI of  $200,000  to support  research  and
clinical  work being  performed at CMMI,  such grants to be expended in a manner
deemed appropriate by the Board of Trustees of CMMI.

     In April 1997,  the Company  launched  LeukoScan in Europe.  All marketing,
selling and distribution rights to the product have been retained by the Company
and the Company continues to build a sales and marketing organization to support
this effort.  The Company has entered  into a  Distribution  Agreement  with Eli
Lilly Deutschland GmbH ("Lilly")  pursuant to which Lilly currently 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.
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 Bergen Brunswig Corporation.  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 their own team of
field specialists as well as the licensed  radiopharmacists who manage their 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. The Company is considering the expansion
of this Letter Agreement to a Marketing and Sales  Agreement,  granting KOL, and
its agents, exclusive rights to market and sell CEA-Scan in the entire U.S.

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  has  entered   into  a   manufacturing   agreement   with  SP
Pharmaceuticals,  formerly the Oncology Division of Pharmacia & Upjohn, pursuant
to  which  SP  Pharmaceuticals   performs  certain  end-stage  portions  of  the
manufacturing  process.  Under the terms of such  agreement,  the  Company  pays
according to an established price structure for these services.

     The Company's Morris Plains  headquarters also houses regulatory,  medical,
research  and  development,   finance,  marketing  and  executive  offices  (see
"Properties").  The Company has now scaled-up to commercial  levels its antibody
purification  and  fragmentation   manufacturing  processes.  The  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 61 issued
United States patents (5 of the Company's earliest patents have now expired) and
200 issued foreign patents,  with 51 United States patent applications  pending,
of which 5 have been allowed,  and 134 foreign patent  applications  pending, of
which 18 have  been  allowed.  Included  in the  foregoing  are 3 United  States
patents  and  foreign  counterparts  of 6 United  States  patents,  to which the
Company has rights pursuant to an exclusive  license granted by Dr.  Goldenberg.
The  Company  also has  certain  rights  with  respect  to  patents  and  patent
applications owned by CMMI, by virtue of a license agreement between the Company
and CMMI.

     The Company's  patents  contain claims  covering its current in vivo cancer
imaging  products,  as well as imaging  and  therapy  products  currently  under
development.

     In  September  1999,  the  Company  was issued a U.S.  patent  covering  an
improvement in a pretargeting system that enhances the delivery of diagnostic or
therapeutic drugs to a target site, which could be a cancer or an infection,  by
using a second  step-clearing  agent to remove the  non-targeted  agent from the
blood.

     In January  2000,  a U.S.  patent was issued to the  Company  describing  a
method of  radiolabeling  proteins by use of a new  radiometal-binding  compound
comprised of mercaptobutyryl glycinate ligands.

     Also in January 2000,  the Company was allowed a U.S.  patent  covering new
methods of treating cancers by a two-step process  involving  bispecific  fusion
proteins.  The fusion  proteins are  engineered  molecules  designed to have two
binding  ends,  one  that  binds  to the  cancer  and  the  other  to a  second,
complementary agent.

     In February 2000, the Company was awarded two U.S.  patents for therapeutic
radiopharmaceuticals.  The first describes new methods of linking  phosphorus-32
and phosphorus-33 to diverse disease targeting  proteins,  such that they retain
the ability to bind to abnormal  cells.  The second  patent  describes a general
method of labeling  proteins with a radioisotope,  providing a one-vial kit, and
is especially  useful for linking Cu-67,  Hg-197,  Pb-203,  Ag-111 and Bi-212 to
antibodies, drugs, cytokines, enzymes, hormones and immune modulators.

     Also in February  2000,  the Company  was  allowed a U.S.  patent  covering
positron  emission  tomography  (PET) with gallium-68  (Ga-68)  chelates,  using
bispecific fusion proteins as the delivery agent.

     In March,  2000, the Company was awarded a U.S.  patent covering the method
of using very small  portions of  antibodies  that bind to diseased  tissues for
better detection during surgical, endoscopic and laparoscopic procedures.

     In April 2000, the Company was allowed a U.S.  patent for a new therapeutic
method  involving  cell-specific  cytokines,  such as IL-15,  to be bound with a
therapeutic  isotope or RNase.  The patent also  covers the use of a  bispecific
antibody  that  recognizes a cancer cell and also a region of IL-15,  permitting
delivery of the IL-15 conjugated to RNase to the cancer cell.

                                       10

     Among the foreign patents issued to the Company during the last fiscal year
were two important Japanese patents, the first covering humanized antibodies and
immunoconjugates  specific  for B-cell  lymphoma  and  leukemia  cells which are
important for the Company's lymphoma  diagnostic and therapeutic  products,  the
second  covering the highly specific  anti-CEA  antibodies used in the Company's
colorectal cancer  diagnostic and therapeutic  products and having potential use
for other types of cancer.

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

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

                                       11
<PAGE>

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

     The  Company has  extended  Dr.  Goldenberg's  employment  agreement  for a
five-year  period,   expiring  on  October  31,  2003.   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  which the Company owns or has  licensed.  In certain  situations,  such
companies  have declined to enter into license  agreements  with the Company and
have raised  questions as to the scope and validity of certain of the  Company's
patents. Discussions are continuing with these companies and the Company intends
to vigorously  protect and enforce its patent  rights.  Although there can be no
assurances as to the outcome of any patent  disputes,  the Company believes that
its patents are valid and will be upheld if challenged.

     In November 1996, the Company  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.  The appeals of the Dutch  infringement and nullity
actions were heard  concurrently on March 2, 2000, and a decision is expected in
November  2000.  A trial on the  German  nullity  action  was held in  Munich on
December 9, 1998,  resulting in maintenance of the patent in amended form, which
continues to protect the Company's  products,  and which the Company believes is
still  infringed by Roche's  immunoassays.  Roche did not appeal.  The Company's
patent counsel believes

                                       12
<PAGE>

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.

     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.  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.

     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 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.

     Generally,  there is a  substantial  period of time  between  technological
conception of a proposed  product and its  availability for commercial sale. The
period  between  technological  conception  and  filing of a  Biologics  License
Application with the FDA is usually five to ten years

                                       13
<PAGE>

for in vivo products and a minimum of two to three years for in vitro diagnostic
products.  The period  between the date of submission to the FDA and the date of
approval  has  averaged  two to four years for in vivo  products,  although  the
approval process may take longer.

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

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

     Pre-clinical  studies are conducted in the  laboratory  and in animal model
systems  to gain  preliminary  information  on the drug's  effectiveness  and to
identify  major safety  problems.  The results of these studies are submitted to
the FDA as part of the IND  application  before approval can be obtained for the
commencement of testing in humans.  The human clinical  testing program required
for a new  biologic or  pharmaceutical  product  involves  several  phases.  The
initial clinical evaluation,  Phase I, consists of administering the product and
testing for safe and  tolerable  dosages while noting the  effectiveness  of the
product at the various dose levels.  Typically,  for cancer  agents,  testing is
done with a small  group of  patients  with  widespread  cancers  that have been
unresponsive  to other forms of  therapy.  Phase II involves a study to evaluate
the  effectiveness  of the product  for a  particular  indication  and to refine
optimal dosage and schedule of administration and identify possible side effects
and  risks in a  larger  patient  group.  When a  product  is  determined  to be
effective in Phase II trials, it is then evaluated in Phase III clinical trials.
Phase III trials consist of additional testing for effectiveness and safety with
a further expanded patient group,  usually at multiple test sites. A therapeutic
cancer  product  must be  compared to standard  treatments,  if such  treatments
exist, to determine its relative effectiveness in randomized trials.

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

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

                                       14

     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.

     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.

 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

                                       15
<PAGE>

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 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  22, 2000,  the Company  employed 65 persons on a full-time
basis,  14 of whom are in research and development  departments,  12 of whom are
engaged in clinical research and regulatory  affairs,  24 of whom are engaged in
operations and manufacturing and quality control,  and 15 of whom are engaged in
finance, administration,  sales and marketing. Of these employees, 18 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

     The Company's products are in various stages of development and face a high
degree of  technological,  regulatory  and  competitive  risk. In addition,  the
Company's products must be approved for marketing by regulatory agencies such as
the FDA (with the exception of CEA-Scan and LeukoScan,  which have been licensed
as  discussed  above),  and no  assurance  can be  given  as to if or when  such
approvals could be  forthcoming.  Product  discovery and development  activities
require  substantial cash outlays.  At least until CEA-Scan and/or LeukoScan are
successfully  commercialized,  future  revenues  will be dependent in large part
upon the Company entering into new arrangements with collaborative  partners and
upon  public  and  private  financings.  No  assurance  can be given  that  such
arrangements  and/or  financings  will be available to the Company on acceptable
terms or at all. In addition, the Company is relying upon its own internal sales
and  marketing  organization  (see  "Marketing,  Sales  and  Distribution").  No
assurance  can  be  given  that

                                       16
<PAGE>

the  Company's  manufacturing  costs will be  economically  viable,  or that the
Company can develop an effective  sales and  marketing  strategy to  effectively
promote any marketed product.

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

     All products in development  face a high degree of  uncertainty,  including
the following:  (i) the Company may not receive  regulatory  approval to perform
human clinical  trials for the products the Company  currently has planned or it
may be unable to successfully complete ongoing clinical trials; (ii) the results
from  preclinical  studies and clinical  trials may not be indicative of results
that will be obtained in later-stage testing; (iii) the Company may be unable to
timely recruit a sufficient  number of patients for its clinical  trials,  which
may result in  increased  costs and  delays;  (iv) the  Company may be unable to
obtain approval from the FDA and comparable  foreign  authorities  because it is
unable to  demonstrate  that the product is safe and  effective for the intended
use, or obtaining  regulatory approval may take significantly more time and cost
significantly more money than the Company currently anticipates; (v) the Company
may discover  that the product has  undesirable  or  unintended  side effects or
other  characteristics  that  make  it  impossible  or  impracticable  for it to
continue development or which may limit the product's commercial use or may even
result in de-registration for use; (vi) the Company does not expect that any new
product  which is  currently in research and  development  will be  commercially
available for at least several years; (vii) the Company may be unable to produce
the product in commercial  quantities at reasonable cost; (viii) the Company may
be unable to successfully market the product or to find an appropriate corporate
partner,  if  necessary,  to assist the Company in the marketing of the product;
(ix)  the  product  may not gain  satisfactory  market  acceptance;  and (x) the
product  may be  superseded  by  another  product  commercialized  for the  same
indication or use. If the Company is unable to continue to develop products that
it can successfully  market,  its business,  financial  condition and results of
operations will be significantly and adversely affected.

     There  can  be no  assurance  CMMI  will  be  successful  in  its  research
activities or that it will develop any potential products, which can be licensed
by the Company.  On September 19, 2000, the FDA issued a warning letter to CMMI.
The  warning  letter,  relating to an  inspection  of CMMI that ended on May 25,
2000,  cited several alleged  deviations from  applicable  federal  regulations.
Among  other  things,  the  warning  letter  alleged  the  failure  to submit an
Investigational   New  Drug   Application   ("IND")   with  respect  to  certain
investigational products, the administration of investigational drugs without an
IND, the failure to assure proper monitoring of  investigations,  the failure to
assure  that   investigations   are  conducted  in  accordance  with  applicable
investigation  plans and  protocols and certain data  difficulties.  The Company
understands  that CMMI is pursuing these matters  directly with the FDA. The FDA
has  substantial  regulatory  authority  over  both  CMMI and the  Company.  Any
regulatory,  judicial or other  actions taken with respect to CMMI by the United
States government or others could materially adversely affect the Company, given
the relationship between the Company and CMMI.

                                       17
<PAGE>

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

     The Company currently does 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 its products. As a result, it
has entered into  arrangements  with Lilly and ICS to perform such  function for
the foreseeable future. If these agreements are terminated,  the Company will be
required to enter into arrangements with other government approved third parties
in order to be able to distribute  its  products.  The Company will be unable to
continue  to  distribute  its  products  until  an  acceptable   alternative  is
identified.  If the Company were even only temporarily  unable to distribute its
products, its business could be significantly and adversely affected.

     CEA-Scan and certain of the Company's other imaging agents are derived from
ascites fluid  produced in mice,  which are provided by a third-party  supplier.
Regulatory  authorities,  particularly in Europe,  have expressed concerns about
the use of mice fluid for the  production  of monoclonal  antibodies.  While the
Company believes that its current quality control  procedures  ensure the purity
of the fluid it uses, there can be no assurance that regulatory authorities will
agree that these  procedures  will be adequate  for future  products.  While the
Company is continuing  its  development  efforts to produce  certain  monoclonal
antibodies  using cell culture methods,  this process  constitutes a substantial
production change, which will require additional manufacturing equipment and new
regulatory  approval.  There can be no assurance  that the Company will have the
resources to acquire the  additional  manufacturing  equipment  and resources or
that it will receive the required  regulatory  approval on a timely basis, if at
all. The Company also has contracted  with a third party for the development and
production of certain humanized antibodies;  however,  there can be no assurance
that such efforts will be successful.

     The Company's  commercial  success is highly dependent upon its patents and
other  proprietary  rights that it owns or  licenses.  While it  actively  seeks
patent  protection  both in the United  States  and  abroad for its  proprietary
technology,  there  can  be no  assurance  that  its  key  patents  will  not be
invalidated  or  will  provide  the  Company   protection  that  has  commercial
significance. Litigation may be necessary to protect its patent positions, which
could be costly and time  consuming.  If any of the key patents that the Company
owns  or  licenses  are  invalidated,  its  business  may be  significantly  and
adversely affected. The Company also relies in part on trade secrets, unpatented
know-how and continuing  technological  advancements to maintain its competitive
position.  It is the  practice  of the  Company  to enter  into  confidentiality
agreements with employees,  consultants and corporate sponsors.  There can be no
assurance, however, that these measures will prevent the unauthorized disclosure
or use of the Company's trade secrets and know-how. In addition, other companies
may independently  develop similar trade secrets or know-how or obtain access to
the Company's  trade secrets,  know-how or proprietary  technology,  which could

                                       18
<PAGE>

significantly and adversely affect its business.  Other companies may have filed
applications  for or have been issued  patents and  obtained  other  proprietary
rights to  technology,  which may be potentially  useful to the Company.  If the
Company  determines that the inventions covered by such patents are necessary or
useful for it, it may attempt to license such rights.  There can be no assurance
that such rights will be  available  at all or upon terms the Company  considers
acceptable.  If the Company is unable to obtain such rights,  its business could
be significantly and adversely affected.

     Third-party  payers  are  increasingly  challenging  the  price of  medical
products  and  services.  Several  proposals  have  been made that may lead to a
government-directed national health care system. Adoption of such a system could
further limit reimbursement for medical products,  and there can be no assurance
that  adequate  third-party  coverage will be available to enable the Company to
maintain  price  levels  sufficient  to  realize  an  appropriate  return on its
investment in product development.  In addition,  there can be no assurance that
the U.S.  government  will not  implement a system of price  controls.  Any such
system might  significantly and adversely affect the Company's ability to market
its products profitably. Similar risks are present in foreign markets.

Item 2 -- Properties

     The Company's  headquarters is located at 300 American Road, Morris Plains,
New Jersey,  where it leases  approximately 60,000 square feet. 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.  (See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations - Liquidity and Capital  Resources.") The lease provides for a second
renewal  period of five years  expiring in May 2007. The lease also provides for
an option to purchase the facility,  subject to certain terms and  conditions as
specified in the lease. On May 19, 2000, the Company gave notice to its landlord
that it desired to exercise its right to purchase the facility, which is subject
to  further  negotiation.  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 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 2000.

Executive Officers of the Registrant

                                       19

     Each  of the  Executive  Officers  was  elected  as such  by the  Board  of
Directors of the Company and holds his office at the  discretion of the Board of
Directors or until his earlier death or resignation,  except that Dr. Goldenberg
is employed pursuant to an employment agreement (See "Executive Compensation").

     Dr. David M.  Goldenberg  founded the Company in July 1982,  and since that
time, has been Chairman of the Board of the Company.  Dr.  Goldenberg  served as
Chief  Executive  Officer from July 1982,  through July 1992; from February 1994
through May 1998 and resumed his  responsibilities  as Chief  Executive  Officer
effective July 1999. Dr. Goldenberg was Professor of Pathology at the University
of  Kentucky   Medical  Center  from  1973  until  1983  and  Director  of  such
University's Division of Experimental  Pathology from 1976 until 1983. From 1975
to 1980 he also served as Executive  Director of the Ephraim McDowell  Community
Cancer  Network,  Inc.,  and from 1978 to 1980 he was  President  of the Ephraim
McDowell Cancer Research  Foundation,  Inc.,  both in Lexington,  Kentucky.  Dr.
Goldenberg is a graduate of the  University  of Chicago  College and Division of
Biological  Sciences  (B.S.),  the  University of  Erlangen-Nuremberg  (Germany)
Faculty of Natural Sciences (Sc.D.),  and the University of Heidelberg (Germany)
School of Medicine  (M.D.).  He has written or co-authored more than 950 journal
articles,  book  chapters  and  abstracts  on  cancer  research,  detection  and
treatment,   and  has  researched  and  written   extensively  in  the  area  of
radioimmunodetection  using radiolabeled antibodies. In addition to his position
with the Company, Dr. Goldenberg is President of CMMI, an independent non-profit
research center,  and its clinical unit, the Garden State Cancer Center. He also
holds the position of Adjunct  Professor of Microbiology and Immunology with the
New York Medical  College in Valhalla,  New York. In 1985 and again in 1992, Dr.
Goldenberg received an "Outstanding  Investigator grant" award from the National
Cancer Institute  ("NCI") for his work in  radioimmunodetection,  and in 1986 he
received the New Jersey Pride Award in Science and  Technology.  Dr.  Goldenberg
was  honored as the ninth Herz  Lecturer of the Tel Aviv  University  Faculty of
Life  Sciences.  In  addition,  he  received  the 1991  Mayneord  3M  Award  and
Lectureship of the British  Institute of Radiology for his  contributions to the
development  of  radiolabeled  monoclonal  antibodies  used in the  imaging  and
treatment of cancer.  Dr. Goldenberg was also named the co-recipient of the 1994
Abbott  Award by the  International  Society for  Oncodevelopmental  Biology and
Medicine. Dr. Goldenberg also serves as Chairman of the Board of IBC.

     Cynthia L.  Sullivan has been  employed by the Company  since October 1985,
and has served as Executive  Vice  President and Chief  Operating  Officer since
June 1999. Prior thereto,  she held positions of increasing  responsibilities in
the Company,  including Executive  Director,  Operations from April 1994 to June
1999.  Prior  to  joining  the  Company,  Ms.  Sullivan  was  employed  by Ortho
Diagnostic  Systems,  Inc., a subsidiary of Johnson and Johnson.  Ms. Sullivan's
educational background includes: a BS from Merrimack College, North Andover, MA,
followed by a year of clinical  internship with the school of Medical Technology
at Muhlenberg Hospital, Plainfield, NJ,

                                       20
<PAGE>

resulting in a MT (ASCP)  certification  in 1979. Ms. Sullivan  completed a M.S.
degree in 1986 from Fairleigh Dickinson University,  where she also received her
M.B.A. in December 1991.

     Dr. Hans J. Hansen has been Vice President, Research and Development, since
March 1987.  Effective July 1999,  Dr. Hansen  reduced his  employment  with the
Company to a part-time  basis.  Prior to joining the Company in 1985 as Director
of Cell Biology,  he was for three years the Director of Product  Development at
Ortho Diagnostic Systems,  Inc., a subsidiary of Johnson & Johnson  Corporation,
where he developed monoclonal antibodies for the diagnosis of leukemia and other
cancers.  From 1969 to 1982, Dr. Hansen was with Hoffmann-La  Roche in a variety
of positions,  becoming  Director of the Department of Immunology in 1982. While
at Hoffmann-La Roche, he developed the first in vitro diagnostic CEA immunoassay
and had a major role in  establishing  its clinical  importance in the diagnosis
and management of cancer. Dr. Hansen has spent 38 years conducting  clinical and
basic  research  in the fields of cancer and  autoimmune  disease.  His work has
resulted  in the  issuance  of  over  30  United  States  patents  and  over  90
publications relating to cancer and autoimmune diseases.

     There are no family relationships  between directors and executive officers
except that Dr. Goldenberg and Ms. Sullivan are husband and wife.

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

Overview

     Statements made in this Form 10-K, other than those  concerning  historical
information,  should be considered  forward-looking and subject to various risks
and   uncertainties.   Such   forward-looking   statements  are  made  based  on
management's  belief as well as assumptions  made by, and information  currently
available to, management pursuant to the "safe harbor" provisions of the Private
Securities  Litigation  Reform Act of 1995.  The  Company's  actual  results may
differ  materially  from  the  results  anticipated  in  these   forward-looking
statements as a result of a variety of factors,  including  those  identified in
"Business"  and elsewhere in this Annual Report on Form 10-K for the fiscal year
ended June 30, 2000.

     Since its inception, the Company has been engaged primarily in the research
and  development  and,  more  recently,  the  commercialization  of  proprietary
products  relating  to the  detection,  diagnosis  and  treatment  of cancer and
infectious diseases. The Company has incurred significant operating losses since
its  formation  in 1982 and has not earned a profit since its  inception.  These
operating  losses  and  failure  to be  profitable  have been due  mainly to the
significant  amount of money that the Company  has had to spend on research  and
development.  As of June 30,  2000,  the Company had an  accumulated  deficit of
approximately  $110,000,000.  The  Company  expects to  continue  to  experience
operating  losses  until  such  time,  if at all,  that  it is able to  generate
sufficient  revenues  from  sales of  CEA-Scan'r',  LeukoScan'r'  and its  other
potential products.

     On June 28, 1996, the U.S. Food and Drug  Administration  ("FDA")  licensed
CEA-Scan for use with other standard diagnostic  modalities for the detection of
recurrent and/or metastatic  colorectal cancer. On October 4, 1996, the European
Commission  granted  marketing  authorization  for use of the  product in the 15
countries  comprising the European Union for the same  indication.  On September
16, 1997, the Company received a notice of compliance from the Health Protection
Branch  permitting  it to market  CEA-Scan in Canada for  colorectal  cancer for
recurrent and metastatic colorectal cancer.

     On February 14, 1997,  the Company was granted  regulatory  approval by the
European  Commission  to  market  LeukoScan'r',  an in vivo  infectious  disease
diagnostic  imaging  product,  in all 15  countries  which  are  members  of the
European  Union,  for  the  detection  and  diagnosis  of  osteomyelitis   (bone
infection)  in long bones and in diabetic foot ulcer  patients.  On December 19,
1996, the Company filed a Biologics  License  Application,  or BLA for LeukoScan
with the FDA for the same  indication  approved  in Europe,  plus an  additional
indication  for the diagnosis of acute,  atypical  appendicitis.  As part of the
review  process,  the  Company is in  discussions  with the FDA to  address  its
comments  regarding the adequacy of the Company's data to support final approval
for these indications.  Consistent with the Compan's decision to focus primarily
on cancer  therapeutic  products,  on April 12, 2000,  the Company  withdrew the
CEA-Scan breast cancer imaging application  submitted on January 26, 1999 to the
European Medicines Evaluation Agency (EMEA). A New Drug Submission for LeukoScan
for the same  indications  as in the U.S.  was  filed  with the HPB in Canada on
March 24,  1998.  The Company  also has decided  not to  continue  pursuing  the
broadening  of its  approval  for  LeukoScan  in Europe to  include  the  acute,
atypical  appendicitis  indication,  but has  instead  published  its  Phase III
efficacy data.

                                       23
<PAGE>

     CEA-Scan and LeukoScan are the only products which the Company is currently
licensed to market and sell.  To date,  the Company has  received  only  limited
revenues from the sale of these  products.  There can be no assurance that these
products will achieve market acceptance or generate  significant  sales.  Unless
the Company receives substantial  revenues from these products,  future revenues
will be  dependent  in large part upon its  receiving  payments  from  corporate
partners  under  licensing and research  agreements or from  government  grants.
However,  there can be no assurance  that the Company will receive such payments
in a timely manner, or at all.

     The Company is also engaged in developing other biopharmaceutical products,
which are in various stages of development and clinical testing.

     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,  currently in 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").

Results of Operations

Fiscal Year 2000 compared to Fiscal Year 1999

     Revenues for fiscal year 2000 were  $5,973,000 as compared to $7,559,000 in
fiscal year 1999,  representing a decrease of $1,586,000.  The product sales for
fiscal year 2000 were  $4,124,000 as compared to $6,097,000 in fiscal year 1999,
representing a decrease of $1,973,000,  mainly due to the  reorganization of the
U.S. and  European  sales  forces,  which  occurred in April 1999.  Research and
development  revenue  for fiscal year 2000  decreased  by $48,000 as compared to
fiscal  1999.  Interest  and other  income for  fiscal  year 2000  increased  by
$438,000.  Interest income  increased by $767,000 due to more cash available for
investments  as a result of infusions of private  equity  capital  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.
Research and  development  costs  decreased by  $1,430,000 as compared to fiscal
year 1999, primarily due to the Company's  restructuring  efforts in fiscal 1999
and lower cost associated with reduced patient  enrollment for clinical  trials.
Cost of goods sold for fiscal  year 2000  increased  by $97,000 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 year
2000 and 1999 does not include  production  costs of certain products sold since
such costs were previously  expensed prior to receiving product approval.  Sales
and  marketing  expenses  for fiscal  year 2000 were  $2,950,000  as compared to
$6,524,000 in fiscal year 1999, representing a decrease of $3,574,000, 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 in recognition  for their efforts with
the  Company's  equity   financings  (see  Note  7  to  Consolidated   Financial
Statements).

                                       24
<PAGE>

     Net  loss  allocable  to  common  shareholders  for  fiscal  year  2000 was
$10,132,000, or $0.23 per share, as compared to $11,688,000, or $0.31 per share,
in fiscal  year 1999.  The lower net loss of  $1,556,000  in 2000 as compared to
1999 primarily resulted from lower operating expenses, partially offset by lower
revenues,  as discussed above, and the accretion of preferred stock dividends on
the Series F Preferred Stock issued in December 1999 (see "Liquidity and Capital
Resources").  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,
which increase was principally  due to the conversion of the Company's  Series F
Preferred  Stock and the  issuance of common  stock  pursuant  to the  Company's
equity financings (see Note 7 to Consolidated Financial Statements).

Fiscal Year 1999 compared to Fiscal Year 1998

     Revenues for fiscal year 1999 were  $7,559,000 as compared to $7,595,000 in
fiscal year 1998,  representing  a decrease of  $36,000.  The product  sales for
fiscal year 1999 were  $6,097,000 as compared to $4,049,000 in fiscal year 1998,
representing an increase of $2,048,000.  The increase in product sales is mainly
due to  increased  market  acceptance  of CEA-Scan and  LeukoScan.  Research and
development  revenue for fiscal year 1999  decreased  by $484,000 as compared to
fiscal 1998, primarily due to the recognition in fiscal year 1998, of previously
deferred revenue received from Pharmacia  Inc.("Pharmacia")  in fiscal year 1997
and a decrease  in grant  revenue of  $176,000.  Interest  and other  income for
fiscal year 1999 decreased by $1,585,000.  Interest income  decreased by $86,000
due to less cash available for investments. Other income decreased by $1,499,000
primarily  due to the receipt,  in November  1997,  of an  arbitration  award of
$1,800,000  including interest from its dispute with Pharmacia.  The decrease in
other  income was offset in part by the receipt and  recognition  in fiscal year
1999 of  $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. (see "Liquidity and Capital Resources").

     Total operating  expenses for fiscal year 1999 were $18,838,000 as compared
to  $19,406,000  in fiscal  year  1998,  representing  a decrease  of  $568,000.
Research and  development  costs  decreased by  $1,638,000 as compared to fiscal
year 1998, primarily due to a decrease in the level of expenditures  required to
obtain  validation  of the  Company's  manufacturing  facility  and  lower  cost
associated with reduced patient  enrollment for clinical  trials.  Cost of goods
sold for fiscal year 1999  increased by $87,000 as compared to fiscal year 1998,
mainly due to increased  product sales.  However,  the decrease in cost of goods
sold as a percentage of product sales reflects the benefit of product sales from
inventory  which was  previously  expensed  by the  Company  prior to  receiving
product  approval.  Sales  and  marketing  expenses  for  fiscal  year 1999 were
$6,524,000  as  compared to  $5,380,000  in fiscal  year 1998,  representing  an
increase of  $1,144,000,  primarily  due to an increase in personnel  associated
with  the  Company's  full-time  oncology  sales  force  in U.S.  and  increased
operating  expenses for Immunomedics  Europe,  which  increased,  by $288,000 as
compared to fiscal year 1998. General and  administrative  costs for fiscal year
1999  decreased  by $161,000 as compared to fiscal year 1998,  primarily  due to
reduced legal costs as a result of the conclusion of the Pharmacia  arbitration,
which was settled in November 1997.

     Net  loss  allocable  to  common  shareholders  for  fiscal  year  1999 was
$11,688,000,  or $0.31 per share, as compared to a net loss of  $11,811,000,  or
$0.32 per share,  in fiscal year 1998. The lower net loss of $123,000 in 1999 as
compared to 1998 primarily  resulted from lower  operating  expenses,  partially
offset by slightly  lower  revenues,  as  discussed  above and the  accretion of
preferred  stock  dividends  on the Series F Preferred  Stock issued in December
1998 (see "Liquidity

                                       25
<PAGE>

and Capital Resources"). In addition, the net loss per share for fiscal 1999 was
positively  impacted by the higher weighted average number of shares outstanding
during such period as compared to fiscal 1998,  which  increase was  principally
due to the conversion of the Company's Series D Preferred Stock (which was fully
converted as of June 30, 1998) and the issuance of common stock  pursuant to the
Company's  Structured  Equity Line Flexible  Financing  Agreement (see Note 7 to
Consolidated Financial Statements).

Liquidity and Capital Resources

     At  June  30,  2000,  the  Company  had  working  capital  of  $40,153,000,
representing  an increase of  $32,330,000  from June 30,  1999.  The Company has
long-term  obligations of $70,000 and certain other lease  obligations (see Note
11 of Notes to Consolidated Financial  Statements).  The net increase in working
capital resulted  principally from the Company's December 1999 and February 2000
private  placements  of  equity  securities  partially  offset  by the net  loss
allocable  to  common  shareholders  during  fiscal  year  2000 of  $10,132,000,
redemption of preferred stock and capital expenditures.

     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.  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 holders at a price equal to 109% of
initial the stated value of $10,000 per share of Series F Stock.

     On December 16, 1999, the Company issued a warrant  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 is 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 is
reached  (December  31,  2000 in this  transaction).  As a result,  the  Company
recognized a proportionate  share of the general and  administrative  expense of
approximately  $925,000  for the fiscal  year  ended June 30,  2000 based on the
estimated value of the warrants as of that date.

     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.

     On February 16, 2000, the Company  completed  another private  placement of
2,350,000  shares of its common  stock at $16.00 per share to several  investors
and received net proceeds of $35,443,000.  Net proceeds from this placement will
be used as required to fund the continued operations of the Company.

     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

                                       26
<PAGE>

purchase  options  for  equipment  previously  leased  through  a  master  lease
agreement. 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  liquid  asset  position,  as  measured  by its  cash,  cash
equivalents  and  marketable  securities,  was  $40,866,000  at June  30,  2000,
representing  an increase of $31,444,000  from June 30, 1999.  This increase was
primarily  attributable to the private placements that occurred in December 1999
and February 2000 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  2001 as a  result  of  planned
operating  expenses  and  capital  expenditures,  offset  in part  by  projected
revenues  from product sales in the U. S. and Europe.  However,  there can be no
assurance, as to the amount of revenues, if any, these products will provide. In
April 1999, the Company implemented a cost reduction program,  which the Company
anticipated saving  approximately $3.5 million during the 12 months ending March
31, 2000.  Primarily due to the restructuring,  the Company has realized savings
of approximately $3.8 million.

     On May 19, 2000, the Company gave notice to its landlord that it desired to
exercise  its right to purchase  the  facilities,  which the  Company  presently
leases at 300 American Road, Morris Plains, New Jersey (see  "Properties").  The
purchase price under the lease is approximately $6.5 million.  The Company plans
to seek mortgage  financing with respect to this purchase.  If such financing is
not  available  to the Company on  acceptable  terms prior to the  closing,  the
Company would expect to fund the purchase price on an interim basis from its own
capital resources and would then likely seek to mortgage the acquired  premises.
No  assurances  can be given that the Company  will be able to secure  favorable
financing either before or after the purchase of these facilities.

     To date, the Company has not generated  positive cash flow from operations.
The Company  believes that its existing  working capital should be sufficient to
meet its capital and liquidity  requirements  for the foreseeable  future.  This
expectation represents a forward-looking  statement under the Private Securities
Litigation  Reform Act of 1995.  Actual results could differ materially from the
Company's  expectation  as a result  of a number  of  risks  and  uncertainties,
including the risks described under "Business"  presented  elsewhere herein. The
Company's  working  capital and working  capital  requirements  are  affected by
numerous  factors and there is no  assurance  that such  factors will not have a
negative  impact  on the  Company's  liquidity.  Principal  among  these are the
success of its product commercialization and selling 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  and  clinical  trials of its  proposed  products and
regulatory  filings  for new  indications  of  existing  products.  There can no
assurance that any additional  financing will be available to the Company at all
or on terms it finds  acceptable  or that the terms of such  financing  will not
cause substantial dilution to existing stockholders.

     The Company intends to supplement its financial resources from time to time
as  market   conditions   permit  through   additional   financing  and  through
collaborative  marketing and distribution  agreements.  The Company continues to
evaluate  various  programs to raise  additional  capital and to seek additional
revenues from the licensing of its proprietary technology.  At the present time,
the Company is unable to determine  whether any of these future  activities will
be successful and, if so,

                                       27

the terms and timing of any definitive agreements.

Recently Issued Accounting Standards

     In December  1999,  the staff of the  Securities  and  Exchange  Commission
issued  Staff  Accounting  Bulletin  or SAB  No.  101,  Revenue  Recognition  in
Financial  Statements.  SAB No.101  summarizes  certain of the staff's  views in
applying  generally  accepted  accounting  principles to revenue  recognition in
financial statements,  including the recognition of non-refundable fees received
upon entering into arrangements.  This SAB, as amended, must be adopted no later
than the fourth quarter of fiscal years  beginning  after December 15, 1999. The
Company is in the process of evaluating  this SAB and the effect it will have on
its consolidated financial statements and current revenue recognition policy.

     In June 1998,  Statement of Financial Accounting Standard ("SFAS") No. 133,
Accounting for Derivative Instruments and Hedging Activities,  was issued and is
effective for all fiscal  quarters of all fiscal years  beginning after June 15,
2000. SFAS No. 133, as amended by SFAS No. 137, requires derivative  instruments
to be recognized as Assets and Liabilities in the Company's balance sheet and be
recorded at Fair Value.  The Company is  currently  not party to any  Derivative
Instruments.  Any future transactions  involving Derivative  Instruments will be
evaluated based on SFAS No.133. The Company does not expect the adoption of SFAS
No.  133 to  have a  material  impact  on its  financial  position,  results  of
operations or cash flows.

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.  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 the shorter-end of the maturity  spectrum,  and at
June 30, 2000 most of the  Company's  holdings were in  instruments  maturing in
less than 18 months.

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

     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

     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).

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  as  the  Company  begins
commercialization  of its  products.  The  portfolio at June 30, 2000  primarily
consists of corporate bonds and U.S. government securities.

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.

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

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.
Non-refundable  payments received under licensing arrangements are recognized as
revenue in the period in which they are  received  as no future  performance  is
required by the Company.

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

     In December  1999,  the staff of the  Securities  and  Exchange  Commission
issued  Staff  Accounting  Bulletin  or SAB  No.  101,  Revenue  Recognition  in
Financial  Statements.  SAB No.101  summarizes  certain of the staff's  views in
applying  generally  accepted  accounting  principles to revenue  recognition in
financial statements,  including the recognition of non-refundable fees received
upon entering into arrangements.  This SAB, as amended, must be adopted no later
than the fourth quarter of fiscal years  beginning  after December 15, 1999. The
Company is in the process of evaluating  this SAB and the effect it will have on
its consolidated financial statements and current revenue recognition policy.

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. The Company has not recorded any tax

                                       34
<PAGE>

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

benefits associated with its net deferred tax assets.

Net Loss Per Share

     Basic and diluted net loss allocable to common shareholders is based on the
net loss for the  relevant  period,  adjusted  for  Preferred  Stock  dividends,
divided by the weighted  average number of 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.  For the  purposes of the  diluted  loss per 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,  2000,  1999 and 1998.  The Company has certain  securities
outstanding  at June 30, 2000 that could  potentially  dilute basic earnings per
share in the  future  that  were not  included  in the  computation  of  diluted
earnings  per  share  because  to do so would  have been  anti-dilutive  for the
periods presented.

Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of 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  and  certain  foreign  exchange  changes  and  is  presented  in the
consolidated statements of operations and comprehensive loss.

Employee Stock Options

     The Company  applies  Accounting  Principles  Board ("APB") Opinion No. 25,
Accounting  for  Stock  Issued  to  Employees,  and  related  interpretation  in
accounting  for stock options  issued to employees.  Employee  stock options are
granted with an exercise price equal to the market price and, in accordance with
APB No. 25, compensation expense is not recognized.  Effective July 1, 1996, the
Company  adopted  the  disclosure  provisions  of SFAS No. 123,  Accounting  for
Stock-Based  Compensation.  For the fair  value of the  employee  stock  options
issued see Note 7.

Financial Instruments

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

                                       35

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

instruments.  Long-term debt rates are consistent  with market rates so carrying
value approximates fair value.

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,
2000 and 1999 consist of the following:

6. Other Current Liabilities

     Included  in other  current  liabilities  are  amounts  payable  to medical
institutions   participating  in  the  Company's   clinical  trial  programs  of
approximately  $536,000  and  $640,000 at June 30, 2000 and 1999,  respectively.
Also  included are amounts  payable to various  legal  counsel of  approximately
$494,000 and $260,000, and accrued health insurance liabilities of approximately
$239,000 at June 30, 2000 and 1999.

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  closing  sales  price of  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  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).

     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
has 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  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 a warrant  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 is 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 is
reached  (December  31,  2000 in this  transaction).  As a result,  the  Company
recognized a proportionate  share of the general and  administrative  expense of
approximately  $925,000  for the fiscal  year  ended June 30,  2000 based on the
estimated value of the warrants as of that date.

     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.

     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.

-    The Company  agreed that if, during the twelve  months ending  December 31,
     2000, it desires to conduct a private placement of its securities through a
     placement agent, broker-dealer or finder, it will give an entity associated
     with the  investors in this  financing a right of first refusal to serve as
     the  placement  agent  in  that  transaction.  This  right  was  waived  in
     connection with the Company's February 2000 financing.

     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.  As of  September  22,  2000,  such  investors  in the  aggregate
beneficially owned 8.75% 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") was ratified.
The basic  terms of the 1992 Plan are  substantially  similar to those under the
Company's  1983 Plan.  Under the 1992 Plan,  3,000,000  shares  were  originally
reserved for possible future  issuance upon exercise of stock options,  of which
356,375  were still  available  at June 30, 2000 for future  grant.  At June 30,
2000,  2,113,375  shares of common  stock  were  reserved  for  possible  future
issuance  upon  exercise of stock  options  outstanding  and future stock option
grants.

     In April 2000, David M. Goldenberg,  the Company's Chief Executive  Officer
and his wife, Cynthia L. Sullivan,  the Company's Chief Operating 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 balance sheet as it is related to a
transaction with the Company's equity.

     Pursuant  to the  terms of the 1992  Plan,  each  outside  Director  of the
Company  who had  been a  Director  prior  to July 1 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,  the amount of which is  determined  at the
discretion of the Company's Board of Directors.  For July 1, 2000,  90,000 stock
options were granted to these Directors.

     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.  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:

     The fair value of each option granted during the three years ended June 30,
2000 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, 2000,  1999, and 1998, (III) expected
volatility  of 126% at June 30,  2000,  80% at June 30, 1999 and 42% at June 30,
1998, and (IV) a risk-free interest rate of 5.90%, 5.06% and 5.57% for the years
ended June 30, 2000,  1999 and 1998,  respectively.  The  weighted  average fair
value at the date of grant for options  granted  during the years ended June 30,
2000, 1999 and 1998 was $11.89, $1.26 and $2.55 per share, respectively.

for income  taxes.  Pursuant  to the  accounting  standard,  the tax  effects of
temporary differences that give rise to

</TABLE>

     The  valuation  allowances  for fiscal years 2000,  1999 and 1998 have been
applied to offset the deferred tax assets in recognition of the uncertainty that
such tax benefits  will be realized.  The  valuation  allowances  as of June 30,
2000, 1999 and 1998 include  $6,353,000,  $4,886,000 and $4,316,000  relating to
fiscal  years  2000,  1999 and 1998  operations,  respectively.  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.

     At  June  30,  2000,   the  Company  has  available   net  operating   loss
carryforwards  for  federal  income  tax  reporting  purposes  of  approximately
$119,000,000,  which expire at various dates between 2001 and 2019.  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 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  $14,700,000  relates to a tax
deduction for  non-qualifed  stock  options.  The Company will increase  capital
contributed  in excess of par when these benefits are realized for tax purposes.
The Company  made no payments of federal or state  income taxes during the years
ended June 30, 2000, 1999 and 1998.

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, Chief Executive Officer
and the 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 2000 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. Certain employees of CMMI serve as consultants to the Company.

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

     CMMI is currently  conducting  basic research and patient  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 2000,  1999
and 1998.

     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  $128,000,  $45,000 and $98,000 during the years ended
June 30, 2000, 1999 and 1998, respectively.  The Company also provides CMMI with
laboratory materials and supplies.

     During each of the fiscal  years 1999 and 1998,  the Board of  Directors of
the  Company  authorized  grants to CMMI of  $200,000  to support  research  and
clinical  work being  performed at CMMI,  such grants to be expended in a manner
deemed appropriate by the Board of Trustees of CMMI.

     On September 19, 2000, the FDA issued a warning letter to CMMI. The warning
letter,  relating to an  inspection  of CMMI that ended on May 25,  2000,  cited
several  alleged  deviations from applicable  federal  regulations.  Among other
things, the warning letter alleged the failure to submit an Investigational  New
Drug Application ("IND") with respect to certain  investigational  products, the
administration  of  investigational  drugs without an IND, the failure to assure
proper monitoring of investigations,  the failure to assure that  investigations
are conducted in accordance  with applicable  investigation  plans and protocols
and certain data  difficulties.  The Company  understands  that CMMI is pursuing
these  matters  directly  with  the  FDA.  The  FDA has  substantial  regulatory
authority  over both CMMI and the  Company.  Any  regulatory,  judicial or other
actions  taken with respect to CMMI by the United  States  government  or others
could materially  adversely affect the Company,  given the relationship  between
the Company and 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.  The
parties  contemplate  that other  Company  products  may be  handled  under this
arrangement when appropriate.

     On November  28,  1997,  the Company was awarded  $1.8  million,  including
interest,  from its arbitration  claim against  Pharmacia for breach of contract
and fiduciary  duty arising out of the license  agreement  with a predecessor of
Pharmacia that had been  terminated in 1995. This amount was recognized as other
revenue in fiscal year 1998.  Additionally,  the Company recognized as revenue a
portion of funds  previously  received  from  Pharmacia  pertaining  to CEA-Scan
clinical trials for which the Company no longer has an obligation.  Such amounts
had been recorded as deferred revenue.

     Effective as of April 6, 1998, the Company appointed a subsidiary of Bergen
Brunswig Specialty Corporation 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.

            Notes to Consolidated Financial Statements - (Continued)

     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.  Goldenberg  and IMG have entered into
an operating  agreement (the "IMG Operating  Agreement") which 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. 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. The Company is considering the expansion
of this Letter Agreement to a Marketing and Sales  Agreement,  granting KOL, and
its agents, exclusive rights to market and sell CEA-Scan in the entire U.S.

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

                                       44

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

as provided in the Agreement.  Dr. Goldenberg will receive an annual base salary
of not less than  $220,000,  subject to increases as  determined by the Board of
Directors.  Effective  July 1,  2000,  the  Board  of  Directors  increased  Dr.
Goldenberg's  annual base salary to  $300,000.  The Company has agreed to extend
Dr.  Goldenberg's  employment  agreement for a five-year period which expires on
October  31,  2003.   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,  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, 2000,
1999 and 1998, 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 two 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).

     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. The lease provides for a
second  renewal  period of five years expiring May 2007. The lease also provides
for an option to purchase the facility,  subject to certain terms and conditions
as  specified  in the lease.  On May 19,  2000,  the Company  gave notice to its
landlord that it desired to exercise its right to purchase the  facility,  which
is subject to further  negotiations.  The purchase price under the lease will be
based on fair market value of the facility  which is estimated at $6.5  million.
Rental expense related to

            Notes to Consolidated Financial Statements - (Continued)

this lease was  approximately  $441,000,  $425,000  and $425,000 in fiscal years
2000, 1999 and 1998, respectively.  Minimum lease commitments for facilities and
equipment are as follows for fiscal years ending:

                   2001 ............................. $441,000
                   2002 ............................. $441,000
                   2003 ............................. $446,000
                   2004 ............................. $449,000
                   2005 ............................. $452,000

     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
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, 2000, the Company's  indebtedness under this agreement was $228,470 due
in equal monthly  installments over the next 16 months. In the fiscal year ended
June 30, 2000 and 1999, the Company paid $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 year 2000
and 1999, revenues from one major customer amounted to approximately 16% of each
years' total consolidated revenues.

                          INDEPENDENT AUDITORS' REPORT


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

We have audited the  accompanying  consolidated  balance sheets of Immunomedics,
Inc. and subsidiaries as of June 30, 2000 and 1999, 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, 2000. 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,  2000  and  1999,  and the  results  of their
operations and their cash flows for each of the years in the  three-year  period
ended June 30, 2000, in conformity with accounting principles generally accepted
in the United States of America.
