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

         On February 14, 1997,  the Company was granted  regulatory  approval by
the European  Commission to market  LeukoScan(R),  an in vivo infectious disease
diagnostic  imaging  product,  in all 15  countries  which  are  members  of the
European  Union,  for  the  detection  and  diagnosis  of  osteomyelitis   (bone
infection)  in long bones and in diabetic foot ulcer  patients.  On December 19,
1996, the Company filed a BLA for LeukoScan with the FDA for the same indication
approved in Europe,  plus an additional  indication  for the diagnosis of acute,
atypical  appendicitis.  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
is examining other applications for the product.

         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").

                                       1
<PAGE>

         The  Company  also is applying  its  expertise  in antibody  selection,
modification  and  chemistry  to develop  therapeutic  products for cancer using
humanized  monoclonal  antibodies  labeled with radioisotopes or conjugated with
drugs or  unlabeled  monoclonal  antibodies.  The Company has been  conducting a
multicenter   Phase   I/II   clinical   trial  with   LymphoCide(TM)   (formerly
ImmuRAIT-LL2),  a non-Hodgkin's B-cell lymphoma therapeutic product.  This trial
was designed to obtain knowledge about targeting and dosing with the murine form
of the monoclonal  antibody.  The Company has now advanced the humanized form of
LymphoCide into Phase I/II clinical trials, evaluating the agent as an unlabeled
(non-isotopic)  therapeutic  product  and as a  yttrium-90  labeled  therapeutic
product,  and has  discontinued  trials  with the  murine  form  (see "In  Vivo"
Therapeutic Products").  A Phase II clinical trial has been completed in Germany
for solid tumor therapy with CEA-Cide(R), labeled with iodine-131, for treatment
of patients with small volume,  inoperable,  metastatic  colorectal  cancer. The
Company also is evaluating  CEA-Cide,  labeled with yttrium-90,  in a Phase I/II
clinical  trial, in patients with  colorectal and pancreatic  cancers.  CEA-Cide
targets  receptor  sites on  CEA-expressing  solid  tumors of the breast,  lung,
digestive and other organ systems.

         The Company is 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. (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' sales and 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 ("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 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").  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  Coulter's  interests  in IBC are  49.55%  and  43.45%  respectively.
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 Coulter may sell any portion of its interest in IBC without first  providing

                                       2
<PAGE>

the other with a right of first refusal with respect to such sale, provided that
after a public offering of IBC securities,  IMG and 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 (the "IMG Operating
Agreement") which establishes their relative rights and obligations (see Note 11
to Consolidated Financial Statements).

         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 Imaging Products

         The Company's in vivo imaging  products  utilize  radioimmunodetection,
which involves injecting a patient with a radioisotope linked, or conjugated, to
an antibody.  An antibody is a protein that can recognize and selectively attach
itself to a specific  substance called an antigen.  Such antigens are present on
tumor cells,  white blood cells that accumulate at the sites of infections,  and
other  disease  entities.  By attaching a  radioisotope  to a  disease-targeting
antibody,  the  radioisotope  may be delivered to a disease site for imaging.  A
gamma camera (standard nuclear medicine equipment used for imaging) is then used
to 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 technetium-99m is added to the vial
in a saline solution,  the product is ready for injection in approximately  five
minutes.

                                       3

         On June 28, 1996, the FDA licensed CEA-Scan 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  for  recurrent  and
metastatic  colorectal  cancer.  In addition,  the Company has six other in vivo
imaging  products  or  indications  in various  stages of  clinical  testing and
regulatory  review by the FDA -- five for cancer imaging  (CEA-Scan for lung and
breast  cancer,  AFP-Scan  for liver and germ cell  cancer  and  LymphoScan  for
non-Hodgkin's lymphoma) and one for imaging infectious diseases (LeukoScan).

         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 are  currently  being  discussed  with FDA and CPMP
officials  to  determine  whether  such  data will  support  the  submission  of
applications for this additional indication in the U.S.
and Europe, respectively.

         LeukoScan is a monoclonal  antibody  fragment which seeks out and binds
to granulocytes  (white blood cells) associated with a potentially wide range of
infectious 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).

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

                                       4
<PAGE>

clinical  trial  with  the  murine  form of its  non-Hodgkin's  B-cell  lymphoma
proposed therapeutic product,  LymphoCide. This product consists of a monoclonal
antibody,  highly  specific in  targeting  B-cell  lymphomas,  labeled  with the
radioisotope  iodine-131.  In this  Phase  I/II  clinical  trial of  LymphoCide,
several  patients,  all of whom were  late-stage and were  unresponsive to other
therapies,  experienced  varying  degrees of tumor  regression.  Reversible bone
marrow  toxicity  also was  observed.  By  conducting  this  trial,  the Company
increased  its knowledge of antibody  targeting and dosage.  The Company has now
advanced its humanized  antibody program into Phase I/II clinical trials and has
discontinued its trials with the murine antibody form of LymphoCide. The Company
is currently evaluating LymphoCide in Phase I/II studies at several sites in the
U.S. and Europe.  The product is being  evaluated  as an  unlabeled  antibody or
conjugated with the therapeutic isotope,  yttrium-90. These initial studies have
indicated  that both forms of the product show  clinical  responses  (partial or
complete  remissions),  even when patients failed chemotherapy or prior antibody
therapy. In February,  1999, the Company entered into a Cooperative Research and
Development  Agreement  ("CRADA")  with the National  Cancer  Institute  ("NCI")
covering the development and use of its humanized  lymphoma antibody  conjugated
to recombinant  ribonucleases  as a potential new anticancer  agent. The Company
contributed  its  humanized  lymphoma  antibody  and  the  NCI  contributed  the
recombinant ribonucleases.  The antibody delivers the conjugated ribonuclease to
the cancer cell where it destroys the cell's  ribonucleic  acid (RNA),  which is
essential for cell  division.  A Phase II clinical trial has been completed with
the Company's colorectal cancer therapeutic,  CEA-Cide. 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,  labeled with  yttrium-90.  This trial will evaluate
the safety of the product in patients with colorectal or pancreatic  cancer. The
Company is currently conducting,  in collaboration with The Center for Molecular
Medicine and Immunology ("CMMI") (also known as the Garden State Cancer Center),
and other academic or research  centers,  research on murine and humanized forms
of targeting antibodies,  alternative  radioisotopes and new conjugation methods
(see "Research Programs").


Research Programs

         The  Company  incurred  approximately   $10,100,000,   $11,738,000  and
$13,114,000,  in total research and development  expense during its fiscal years
ended June 30, 1999, 1998 and 1997, 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 five fiscal years, the Company,  in collaboration  with
CMMI and other investigators,  continued to demonstrate  successful targeting in
patients with the Company's  humanized  monoclonal  antibodies (hMN-14 and hLL2)

                                       5
<PAGE>

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
out-patient 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,  and early reports are promising, with
some  evidence of tumor  regression.  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 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  1999,   the  Company  continued  to  improve  its
proprietary  methods for  technetium-99m  radiolabeling of peptides,  which were

                                       6
<PAGE>

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  novel  synthetic   methods  have  also  been  used  to  prepare
chelate-peptide  conjugates  which  can  be  radiolabeled  with  indium-111  and
yttrium-90.

Intraoperative Cancer Detection

         The  Company  has  been  developing   intraoperative  cancer  detection
applications with CEA-Scan, utilizing hand-held, radiation-detecting probes. The
Company has learned that surgeons have  successfully  used CEA-Scan in this way,
within 48 hours of its injection and external imaging.  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  endoscopic  applications.
The Company has  discussed  with the FDA the use of CEA-Scan  with gamma probes,
and is  planning  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

         During  fiscal  year 1999,  the  Company  was  awarded two phase I SBIR
grants  from the NCI,  for  $100,000  each.  The first  grant will  support  the
development  of a  bacterial  expression  system for  producing  a  ribonuclease
(RNase).  Once  incorporated  into the cancer cells,  the RNase  destroys  their
capability  to reproduce,  bringing  them to rapid cell death.  The second grant
will support the  development  of bispecific  antibodies  that will be used in a
two-injection  protocol,  optimizing the delivery of  radionuclides  to cancers.
This method is expected to dramatically  reduce background  radionuclide  uptake
levels in all  non-cancerous  tissues,  thereby leading to greater contrast with
diagnostic agents and improved therapeutic ratios with radioimmunotherapy.

         In September,  1999, the Company was awarded a phase II SBIR grant from
the NCI for $750,000.  The grant will support the  development  of a therapeutic
product for  metastatic  breast cancer.  This project  includes the use of a new
humanized antibody specific for breast, ovarian, lung and prostate cancers. This
new  antibody  has a unique  feature of  internalizing  into  cancer  cells very
rapidly.  The Company  anticipates  delivering  higher  cancer  killing doses of
isotopes or drugs to tumor sites without affecting normal cells.


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

                                       7
<PAGE>

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 December 31, 1999,  with the
Company having the right to seek good-faith  negotiation to extend the agreement
for an additional five-year period.

         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 $45,000, $98,000 and $69,000 during the years ended June
30, 1999, 1998 and 1997, respectively.  The Company also provides, at no cost to
CMMI, laboratory materials and supplies in connection with research conducted in
areas of potential interest to the Company.

         During each of the years ending June 30, 1999,  1998 and 1997 the Board
of Directors of the Company made 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.  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 fiscal years 1999, 1998 and 1997.


Marketing, Sales and Distribution

In Vivo Products

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

         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

                                       8
<PAGE>

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.   The  Company  continues  to  have  discussions  with  other
radiopharmacy chains regarding arrangements which will make CEA-Scan more widely
available to hospitals  and clinics,  but as of the date of this report no other
agreements  have  been  consummated,  and  there  can be no  assurance  that any
additional agreements will be entered into.

         On April  5,  1999,  the  Company  announced  the  implementation  of a
cost-reduction  and  restructuring   plan  which  included   company-wide  staff
reductions  and the  redeployment  of the sales force.  The U.S. sales force for
CEA-Scan  became  focused on new  customers in major  medical  centers that will
become  colorectal cancer "Centers of Excellence." The Company intends to assess
this strategy for future  products,  including  LeukoScan.  The Company believes
this new focus would improve the  productivity  of its sales force and marketing
efforts,  as well as enhance  its  ability to  in-license  imaging  and  therapy
products from other companies desiring a highly skilled sales force.


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

                                       9
<PAGE>

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
59 issued United States patents 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 8 United States  patents and their foreign  counterparts,  to
which the Company has rights  pursuant to an  exclusive  license  granted by Dr.
Goldenberg.  The  Company  also has certain  rights with  respect to patents and
patent  applications owned by CMMI, by virtue of a license agreement between the
Company and CMMI.

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

         In July,  1998,  two U.S.  patents were issued to the Company  covering
nuclear  imaging  and  MRI  (Magnetic   Resonance  Imaging)  methods  to  reveal
anatomically displaced cells or tissues by using very special detector molecules
to locate  abnormal  cells or  tissues  by  external  scanning  of the  patient.
Management of  endometriosis,  a painful and debilitating  disease  occurring in
about  10-15%  of women  ages  20-40,  may be  improved  as a result of this new
targeting method.

         Also in July,  1998, the Company was issued  another U.S.  patent which
provides  a method  of  protecting  non-cancerous  tissues  and  cells  from the
toxicities of treating  cancer with  radiation or  chemotherapy  by  selectively
targeting  protective drugs to such tissues.  Therapeutic  doses of radiation or
drugs can then be given to the patient killing cancer cells while normal tissues
and cells, such as in bone marrow, are protected by the drug.

         In August, 1998, two U.S. patents were issued to the Company. The first
covers  humanized  antibodies  that target  lymphoma and leukemia  cells and are
useful for  imaging  and  therapy,  in  conjunction  with drugs and  radioactive
agents.  The  second  patent  has  broad  claims to a new type of  vaccine  that
operates in stages and is able to induce a more complete immune response against
antigens found on tumors and infectious agents.

         In September,  1998, a Japanese  patent was issued to the Company which
covers a new product and  technology  for  diagnosing  (by gamma,  positron,  or
magnetic resonance imaging) sites of infection,  as well as treating these sites
by combining an isotope or antimicrobial drug to the new targeting agent.

         In  December,  1998,  the Company  announced  the  issuance of two U.S.
patents,  the first involving  methods to counteract the  complications of organ
graft  rejection.  The method  involves  overcoming the toxicity to normal blood
cells that can occur after immunosuppressive  treatment of patients having organ
transplantation.  The patent covers the administration of certain cytokines with
immunosuppressive   drugs  and  in  combination  with  antibodies  specific  for
T-lymphocytes.  The second  patent  covers a new process to treat  cancers  with

                                       10
<PAGE>

selectively-directed  neutron  irradiation.  The method involves targeting boron
atoms to cancer  cells by means of a  two-step,  "pretargeting"  procedure  that
allows  for high,  selective  uptake  of boron  atoms at the  tumor  site.  When
irradiated,  the boron atoms  convert to  radioisotopes  that emit highly potent
alpha-particles, which are lethal to cells at the site.

         In January,  1999, the Company  announced the issuance of a U.S. patent
comprising a method for  antibody  targeting of  therapeutic  drugs.  The patent
involves a universal  method which permits the therapeutic  drug to be activated
preferentially  at the site of disease.  This method is  applicable  to diseases
such as cancers,  infections,  clots, myocardial infarctions and atherosclerotic
plaques.

         In February, 1999, a U.S. patent was issued to the Company,  claiming a
humanized   monoclonal   antibody   against   carcinoembryonic   antigen  (CEA).
Furthermore, the patent covers conjugates of the antibody, including imaging and
therapeutic  agents.  The Company is  evaluating  this  antibody in  therapeutic
clinical trials in diverse cancers.

         In June,  1999,  a U.S.  patent  was  issued to the  Company,  claiming
another "pre-targeting" method for bringing radioisotopes to a target site using
conjugates of naturally-occurring metal ion chelating proteins.

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

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

                                       11
<PAGE>

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").

         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.  Dr.  Goldenberg  voluntarily
reduced his annual base salary  effective  June 1999 from  $265,000 to $225,000.
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 pays
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.

         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.

                                       12

         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.   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
on the  infringement  claim  before the  Patent  Court in The Hague on August 8,
1997,  resulting in dismissal of the action.  The dismissal was based in part on
the trial judge's  inability to resolve  validity issues without a full trial of
the nullity 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.  Affirmation  of the  validity  of this
patent is important  because its claims also  protect the  antibody  used in the
Company's in vivo CEA-Scan  cancer imaging  product and CEA-Cide  cancer therapy
product,  as well as the use of highly  specific CEA  antibodies for a number of
other uses. In December, 1998, the German Patent Court upheld the patent for the
Company's CEA antibodies.  Additionally, an anonymous Opposition challenging the
validity of a corresponding Japanese patent was also defeated.

         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 of 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 several  foreign
countries.  The mark  "IMMUSTRIP" is registered in the United States and Canada.
The mark "CEA-SCAN" is registered in the United States and 8 foreign  countries,
an  application  is  pending  in 1 foreign  country,  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 9 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,

                                       13
<PAGE>

refusal  of the FDA to  approve  product  license  applications  or to allow the
Company to enter into supply contracts,  and criminal prosecution.  The FDA also
has  the  authority  to  revoke   previously   granted   product   licenses  and
establishment licenses.

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

         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

                                       14
<PAGE>

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

         The  Company  seeks to have its  proposed  products,  when  applicable,
designated as "Orphan  Drugs" under the Orphan Drug Act of 1983. The Orphan Drug
Act  generally  provides  incentives  to  manufacturers  to  develop  and market
products to treat relatively rare diseases,  i.e., diseases affecting fewer than
200,000  persons in the United  States.  The  Company has  received  Orphan Drug
designation  for,  among  others,  AFP-Scan,   LymphoScan  and  LymphoCide,  the
Company's liver and germ-cell imaging, lymphoma imaging and lymphoma therapeutic
products,  respectively,  CEA-Scan for the diagnosis of medullary thyroid cancer
and for 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 Good Manufacturing
Practices ("GMP").  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   product  must  be  in  compliance   with  FDA  regulatory
requirements.  Failure  to  comply  with  applicable  requirements  relating  to
manufacture,  distribution  or promotion can lead to FDA demands that production
and  shipment  cease,  and, in some cases,  that  products  be  recalled,  or to
enforcement  actions  that  can  include  seizures,   injunctions  and  criminal
prosecution.  Such  failures,  or new  information  reflecting on the safety and
effectiveness  of the drug that comes to light after approval,  can also lead to
FDA withdrawal of approval to market the product.

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

         The Company's  ability to commercialize  its products  successfully may
also  depend in part on the extent to which  reimbursement  for the cost of such
products  and  related  treatment  will  be  available  from  government  health
administration authorities, private health insurers and other organizations.

         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

                                       15
<PAGE>

foreign regulations. The Company believes its operations comply, in all material
respects, with applicable environmental laws and regulations, and the Company is
continuing  its  efforts  to  ensure  its full  compliance  with  such  laws and
regulations.


Competition

         The biotechnology  industry is highly competitive,  particularly in the
area of cancer  diagnostic,  imaging and  therapeutic  products.  The Company is
likely  to  encounter  significant  competition  with  respect  to its  proposed
products currently under development. A number of companies which are engaged in
the biotechnology  field, and in particular the development of cancer diagnostic
and  therapeutic  products,  have financial,  technical and marketing  resources
significantly greater than those of the Company. Some companies with established
positions in the pharmaceutical industry may be 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 October 7, 1999,  the Company  employed 80 persons on a full-time
basis,  20 of whom are in research and development  departments,  10 of whom are
engaged in clinical research and regulatory  affairs,  15 of whom are engaged in
operations  and   manufacturing,   and  35  of  whom  are  engaged  in  finance,
administration,  sales and marketing. Of these employees, 23 hold M.D., Ph.D. or
other advanced degrees (see "Marketing,  Sales and  Distribution").  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. 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 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 us in the marketing of
the product;  (ix) the product may not gain satisfactory market acceptance;  and
(x) the product may be superceded 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. In addition, if CMMI were no longer to conduct such research and
patient  evaluations,  the Company  would have to make  arrangements  with third

                                       17
<PAGE>

parties for the performance of this aspect of our clinical  research,  which may
prolong and increase expenses  associated with pre-clinical  testing and initial
clinical trials.

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

         The Company 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 effected.

         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

                                       18
<PAGE>

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
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
you that such  rights  will be  available  at all or even 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.  The
lease  provides for a second renewal period of five years expiring on May, 2007.
The lease  provides for an option to purchase the  facility,  subject to certain
terms and  conditions as specified in the lease.  The  Company's  manufacturing,
regulatory,  medical, research and development laboratories,  finance, marketing
and  executive  offices  are  currently  located  in  this  facility,  occupying
approximately   60,000  square  feet.   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 involved in various claims and litigation arising in the
normal course of business.  Management  believes that the outcome of such claims
and  litigation  will  not  have a  material  adverse  effect  on the  Company's
financial position and results of operations.


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 1999.

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, 1999.

         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, 1999,  the Company had an accumulated
deficit  of  approximately  $99,000,000.  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,  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 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 their comments
regarding the adequacy of the Company's data to support final approval for these
indications.  The Company is confident that it can bring these  discussions with
the FDA to  successful  and timely  closure.  In the  meantime,  the  Company is
continuing  to  implement  its plans for  market  introduction,  and is  working
diligently on preparation to bring this new product to the U.S. marketplace.

         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.

                                       23
<PAGE>

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.

         While the Company  expects to receive  approval  from the FDA to market
and sell  LeukoScan in the United  States,  there can be no assurance  that such
approval will be received in a timely manner, if at all.

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


Results of Operations
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

                                       24
<PAGE>

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  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).

Fiscal Year 1998 compared to Fiscal Year 1997

         Revenues for fiscal year 1998 were $7,595,000 as compared to $3,841,000
in fiscal year 1997,  representing an increase of $3,754,000.  The product sales
for fiscal year 1998 were  $4,049,000  as compared to  $1,387,000 in fiscal year
1997, representing an increase of $2,662,000.  The increase in product sales was
attributable  to  increased  market  acceptance  of  CEA-Scan  and the launch of
LeukoScan  in April  1997.  Royalties  and  license  fees for  fiscal  year 1998
decreased by $554,000,  primarily due to the receipt of a nonrecurring  $500,000
license  fee  from a  corporate  partner  in  fiscal  year  1997.  Research  and
development  revenue for fiscal year 1998  increased  by $550,000 as compared to
fiscal year 1997, due to the recognition of previously deferred revenue received
from  Pharmacia.  Interest  and other  income for fiscal year 1998  increased by
$1,096,000,  primarily due to the receipt of an arbitration award of $1,800,000,
including  interest,  in its  dispute  with  Pharmacia  offset by a decrease  in
interest  income  of  $721,000  due to  reduced  levels  of cash  available  for
investments.

         Total  operating  expenses  for fiscal  year 1998 were  $19,406,000  as
compared  to  $17,775,000  in fiscal  year 1997,  representing  an  increase  of
$1,631,000.  Research and development  costs decreased by $1,376,000 as compared
to fiscal year 1997,  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 1998 increased by $177,000 as compared to fiscal year
1997,  mainly due to increased product sales. 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 1998 were  $5,380,000  as compared to
$1,792,000  in  fiscal  year  1997,  representing  an  increase  of  $3,588,000,
primarily due to expenses of $1,753,000 associated with the Company's then newly
hired  full-time  oncology sales force and operating  expenses for  Immunomedics
Europe  which  increased by  $1,632,000  as compared to the same period of 1997.
General and  administrative  costs for fiscal year 1998 decreased by $758,000 as
compared to the same period of 1997,  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 the fiscal year 1998 was
$11,811,000,  or $0.32 per share, as compared to a net loss of  $13,947,000,  or
$0.39 per share,  in fiscal year 1997.  The lower net loss of $2,136,000 in 1998
as compared to 1997 primarily resulted from higher revenues, partially offset by
higher operating  expenses,  as discussed  above. In addition,  the net loss per
share for fiscal year 1998 was impacted by the higher weighted average number of
shares  outstanding  during such  period as compared to fiscal year 1997,  which
increase  was  principally  due to the  conversion  of the  Company's  Series  D
Preferred Stock (see Note 7 to Consolidated Financial Statements).

Liquidity and Capital Resources

         At June 30,  1999,  the  Company  had  working  capital of  $7,823,000,
representing  an increase of $2,357,000 from June 30, 1998. The Company has long
term obligations of $228,000 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  1998  private  placement
partially offset by the net loss allocable to common  shareholders during fiscal
year 1999 of $11,688,000 and capital expenditures.

         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 the 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  increases at the rate of 4% per
annum.  The increase in stated value of the Series F Stock  totaled  $281,944 at
June 30,  1999.  The  Series F Stock  became  convertible  at the  option of the
investors,  in whole or in part, on June 8, 1999. The number of shares of common
stock  issuable  upon  conversion  of each  share  of  Series  F  Stock  will be
determined  by dividing  the stated value of $10,000 plus an accretion of 4% per
annum, by the conversion  price then in effect.  In accordance with the terms of
the Series F Preferred  Stock,  the Company was required to recognize an assumed
incremental yield of $127,500 (calculated at the date of issuance and based on a
beneficial  conversion feature).  Such amount was amortized as a preferred stock
dividend over a six month period beginning with the date of issuance.

         The conversion price is equal to:

         (a)      the Variable Price, if such Variable Price is less than $2.50;
                  except that prior to December 9, 1999, subject to acceleration
                  in certain instances, if the  Variable  Price is greater  than
                  $2.25  and  less  than $2.50,  the conversion price will equal
                  $2.50;

         (b)      $2.50, if the Variable Price is equal to or greater than $2.50
                  and less $3.75; and

         (c)      $2.50  plus  one-half  of  the  amount,  if any,  by which the
                  Variable Price exceeds $3.75, if the Variable Price is greater
                  that $3.75.

                                       26
<PAGE>

         The $2.50  conversion price was set based on 125% of the "Initial Fixed
Price" of $2.00,  which was set as the  average  closing bid price of the Common
Stock during the 20 trading days ended June 6, 1999.  The "Variable  Price" will
be equal to the average of the 15 lowest closing bid prices for the Common Stock
during the 45 trading days immediately preceding a conversion date.
         If all the Series F Stock had been  converted as of September 24, 1999,
the Company would have been required to issue approximately 10,974,000 shares of
Common Stock.

         Under  certain  circumstances  and at certain  prices,  the Company may
elect to redeem any shares of Series F Stock. Under certain  circumstances,  the
Company may require the investors to convert  their Series F Stock.  The Company
has granted the investors certain participation rights if the Company issues any
future floating rate convertible  securities.  The holders of the Series F Stock
generally  do not have the right to vote for the  election  of  directors  or on
other matters, except to the extent their rights would be adversely affected.

         Upon the occurrence of certain  events,  the Company may be required to
redeem the Series F Stock,  pay certain  penalties  and/or adjust the conversion
price. These events include the following:

         (a) If the Company  consolidates,  merges or  otherwise  combines  with
another entity and as a result the stockholders of the Company immediately prior
to such transaction do not retain sufficient voting power to elect a majority of
the board of  directors of the new or combined  entity,  then the holders of the
Series F Stock may  require the  Company to redeem  their  shares at a price per
share equal to the greater of (1) 125% of the stated  value of $10,000 per share
plus the  accretion of 4% per annum,  and (2) the value of the Common Stock that
would be  issuable  upon  conversion  of the  Series F  Stock.  However,  if the
consolidation,  merger  or other  business  combination  occurs as a result of a
proxy  solicitation which was not approved or recommended by the Company's Board
of Directors, then, if the holders exercise their redemption rights, the Company
may, in lieu of  redemption,  either (y) readjust the Initial Fixed Price to 80%
of the lower of (A) the lowest Variable Price during the period beginning on the
date such  solicitation is announced and ending on the date such solicitation is
consummated,  abandoned  or  terminated  or (B) the Initial  Fixed Price then in
effect,  or (z) pay a penalty of 1% per day of the stated  value of $10,000  per
share plus the accretion of 4% per annum for a maximum of 10 days in any 365-day
period.

         (b) If at least a  specified  percentage  of the  holders of the Common
Stock  accept a  purchase,  tender or  exchange  offer,  then the holders of the
Series F Stock may  require the  Company to redeem  their  shares at a price per
share equal to the greater of (1) 125% of the stated  value of $10,000 per share
plus the  accretion of 4% per annum,  and (2) the value of the Common Stock that
would be  issuable  upon  conversion  of the  Series F Stock.  However,  if such
purchase,  tender or  exchange  offer was not  approved  or  recommended  by the
Company's  Board of Directors;  then, if the holders  exercise their  redemption
rights, the Company may, in lieu of redemption,  either (y) readjust the Initial
Fixed  Price to 80% of the lower of (A) the  lowest  Variable  Price  during the
period beginning on the date such offer is announced and ending on the date such
offer is  consummated,  abandoned or  terminated  or (B) the Initial Fixed Price
then in  effect,  or (z) pay a  penalty  of 1% per day of the  stated  value  of
$10,000 per share plus the accretion of 4% per annum for a maximum of 10 days in
any 365-day period.

         (c) If the Company  completes a sale of all or substantially all of its
assets, then the holders of the Series F Stock may require the Company to redeem
their shares at a price per share equal to the greater of (1) 125% of the stated

                                       27
<PAGE>

value of $10,000 per share plus the accretion of 4% per annum, and (2) the value
of the Common  Stock  that would be  issuable  upon  conversion  of the Series F
Stock.

         (d) If the  registration  statement  under the  Securities  Act of 1933
covering  the  resale  by  the  investors  of the  Common  Stock  issuable  upon
conversion of the Series F Stock ceases to be available to the investors for the
resale of their shares for more than 10  consecutive  days,  then the holders of
the Series F Stock may require the Company to redeem their shares at a price per
share equal to the greater of (1) 125% of the stated  value of $10,000 per share
plus the  accretion of 4% per annum,  and (2) the value of the Common Stock that
would be  issuable  upon  conversion  of the  Series F  Stock.  However,  if the
unavailability of the registration  statement is not the result of the Company's
failure to use its best efforts,  then, if the holders exercise their redemption
rights, the Company may, in lieu of redemption,  (y) pay a penalty of 1% per day
of the stated value of $10,000 per share plus the  accretion of 4% per annum for
a maximum of 15 days in any 365-day  period,  and (z) readjust the Initial Fixed
Price to 80% of the lowest  Variable  Price during the period  commencing on the
day the  registration  statement  became  unavailable  and ending on the day the
registration statement is again available for use.

         (e) If the  Common  Stock is  delisted  or  suspended  from the  Nasdaq
National  Market  for a period  of more  than five  consecutive  days,  then the
holders of the Series F Stock may require the Company to redeem  their shares at
a price  per  share  equal to the  greater  of (1) 125% of the  stated  value of
$10,000 per share plus the  accretion of 4% per annum,  and (2) the value of the
Common  Stock  that would be  issuable  upon  conversion  of the Series F Stock.
However,  if the Common Stock is delisted from the Nasdaq  National Market then,
if the holders  exercise their  redemption  rights,  the Company may, in lieu of
redemption, (y) readjust the Initial Fixed Price to 68.5% of the lowest Variable
Price during the period  commencing on the date of delisting and  continuing for
45 days  thereafter,  or (z) pay a penalty of 1% per day of the stated  value of
$10,000 per share plus the accretion of 4% per annum for a maximum of 15 days in
any 365-day period.

         Pursuant to its  agreement  with the  investors,  the Company  called a
Special Meeting of Stockholders on March 19, 1999, at which meeting stockholders
approved  the  issuance of any shares upon  conversion  of the Series F Stock in
excess  of  20% of the  number  of  shares  of  common  stock  the  Company  had
outstanding on December 9, 1998 (i.e.,  7,577,617) in accordance  with the rules
and regulations of The Nasdaq Stock Market, Inc.

         Each investor has agreed that if it engages in short sales transactions
or other hedging  activities during the 45 trading days immediately  preceding a
conversion date which involve, among other things, sales of shares of the Common
Stock, the investor will place its sale orders for common stock in the course of
such activities so as not to complete or effect any such sale on any trading day
during such  period at a price  which is lower than the lowest sale  effected on
such day by persons other than such investor or its affiliates.

         Because the market price of the Common Stock is subject to fluctuation,
the Company agreed, pursuant to the terms of a registration rights agreement, to
register  for resale by the  investors  at least 200% of the number of shares of
common stock that would be issuable if all the Series F Stock were  converted as
of the  date  of the  filing  of the  registration  statement  and,  thereafter,
maintain  the  registration  of at least  150% of the number of shares of common
stock that would be issuable if all the Series F Stock were then converted.  The
registration  statement  currently in effect covers  10,000,000 shares of common
stock. If the registration statement is insufficient to permit the resale by the

                                       28
<PAGE>

investors of all the common  shares  issuable  upon  conversion  of the Series F
Stock,  the  investors,  in  addition to any other  remedies,  have the right to
require the Company to redeem all or any  portion of the  remaining  outstanding
shares of Series F Stock (at a price  equal to the greater of 125% of the stated
value of $10,000 per share plus the  accretion  of 4% per annum and the value of
the Common Stock which would have been issued upon conversion) as well as pay to
them a penalty of $5 per share of Series F Stock for each day that sales  cannot
be made.  The  registration  statement  would not cover a  sufficient  number of
shares to permit the  investors to resell all the shares they could acquire upon
conversion  if the  Variable  Price  is less  than  approximately  $1.29  (which
threshold  will increase over time due to the 4% accretion to the stated value).
The Common Stock in the recent past has traded below this price.

         The Company has received a waiver,  dated  October 11,  1999,  from the
holders of the Series F Stock with respect to the rights  discussed above either
to require  redemption or to receive penalties  conditioned upon the Company (a)
filing a registration  statement,  on or before  November 11, 1999,  covering at
least 200% of the number of shares of common stock that would be issuable if all
the  Series  F  Stock  were  converted  as of  the  date  of the  filing  of the
registration  statement  and (b) having  such  registration  statement  declared
effective  on  or  before  December  11,  1999.   However,  if  failure  of  the
registration  statement to be declared effective by December 11, 1999 is not the
result of the Company's  failure to use its best  efforts,  then, if the holders
exercise their redemption  rights,  the Company may, in lieu of redemption,  (y)
pay a penalty  of 1% per day of the stated  value of $10,000  per share plus the
accretion  of 4% per annum for a maximum of 15 days in any 365-day  period,  and
(z) readjust the Initial Fixed Price to 80% of the lowest  Variable Price during
the period commencing on the day the registration  statement became  unavailable
for sale of all the shares and ending on the day the  registration  statement is
again available for use for sale of all the shares. In addition, notwithstanding
whether  or not the  Company  has  used its best  efforts,  if the  registration
statement is not filed by November  11, 1999 and declared  effective by December
11,  1999,  the  investors  also  will be  entitled  to the $5 per  day  penalty
(discussed  above) accruing from the first day that the Company was in breach of
such registration obligation,  which penalties would be significant. The Company
intends to file the registration statement on or before November 11, 1999 and to
use its best  efforts to have it declared  effective  on or before  December 11,
1999.  While the new registration  statement will cover a significant  number of
additional  shares,  the Company would not be required to issue any shares which
are the subject of this additional  registration  statement  unless the Variable
Price at the time of conversion is below $1.29  (increased  over time due to the
4% accretion to the stated value).

         The Company  will also  continue  its  discussions  with the  investors
concerning  a  possible  restructuring  of certain  other  terms of the Series F
Stock. However, there can be no assurance that any restructuring can be obtained
upon terms acceptable to the Company, if at all.

         If the Company  were  required to redeem the Series F Stock or make any
of the  penalty  payments,  it may not have the  financial  ability to make such
payments.  Even if the  Company  did have the  financial  ability  to redeem the
Series F Stock or pay the required  penalties,  such payment could significantly
and adversely affect its financial condition and deplete its cash resources.

         As of  October  7,  1999,  22  shares  of the  Series F Stock  had been
converted into 193,994 shares of Common Stock. If all the remaining  outstanding
shares of Series F Stock had been  converted as of October 7, 1999,  the Company
would have been required to issue approximately  10,836,000 additional shares of
Common Stock.

         On October 28, 1998,  the Company  entered into an Equipment  Financing
Agreement  with the New  England  Capital  Corporation,  pursuant  to which  the
Company has received $450,000, to be repaid over a 36-month period. The proceeds
of such financing were used to exercise the early purchase options for equipment
previously leased through a master lease agreement.  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  $9,422,000  at  June  30,  1999,
representing  an increase of $1,839,000  from June 30, 1998.  It is  anticipated
that working capital and cash, cash equivalents,  and marketable securities will
decrease during fiscal year 2000 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  anticipates  saving
approximately  $3.5 million during the next 12 months.  As part of such program,
the workforce was reduced by twelve  employees,  for which the Company  incurred
severance expense of approximately $20,000.

         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  through  fiscal year
2000 based on reduced  spending  levels,  if necessary.  However,  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,  and access to  capital  markets  that can
provide the Company with the  resources  when  necessary  to fund its  strategic
priorities. Without a significant increase in product revenues or other infusion
of capital,  the Company will be required to significantly  reduce its operating
expenses,  including  the amount of resources  devoted to  marketing  and sales,
product  development  and clinical  trials,  which could have a significant  and
adverse  effect  on the  Company.  The  Company  believes  that it will  require
additional financial resources by the beginning of fiscal year 2001 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, the terms and timing of any definitive agreements.

Impact of Year 2000

         The Company has completed a review of its business  systems,  including
its computer systems and manufacturing equipment, and has sent written inquiries
to its customers,  distributors  and vendors as to their progress in identifying

                                       30
<PAGE>

and  addressing  problems that their systems may face in correctly  interpreting
and  processing  date  information  as the year 2000  approaches and is reached.
Based on this review,  the Company is  implementing  a plan to achieve year 2000
compliance  which the Company expects to complete by October,  1999. The Company
believes  that it will  achieve year 2000  compliance  in a manner which will be
non-disruptive to its operations. In addition, the Company has commenced work on
various types of contingency  planning to address  potential  problem areas with
internal systems, suppliers and other third parties which the Company expects to
complete  by  October,  1999.  Year 2000  compliance  should not have a material
adverse  effect on the Company,  including  the Company's  financial  condition,
results of  operations  or cash flow.  The  Company has  incurred  approximately
$120,000  of costs to date  related  to year 2000.  The  Company  estimates  the
additional cost of its year 2000 efforts to be  approximately  $130,000 based on
management's  current assessment and is subject to change.  This additional cost
will  mainly  consist of  replacing  its  current  telecommunication  system and
upgrading certain equipment.

         However,  the Company  may  encounter  problems  with  supplier  and/or
revenue sources which could adversely affect the Company's financial  condition,
results of operations or cash flow.  The Company cannot  accurately  predict the
occurrence  and/or  outcome of any such  problems,  nor can the dollar amount of
such  problems be  estimated.  In addition,  there can be no assurance  that the
failure  to  ensure  year  2000  compliance  by a third  party  would not have a
material adverse effect on the Company.


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.

         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, 1999 virtually all of the Company's holdings
were in instruments maturing in one year or less.

                               Immunomedics, Inc.
                   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. The Company
believes  that its existing  working  capital  should be  sufficient to meet its
capital and liquidity requirements through fiscal 2000 based on reduced spending
levels, if necessary.

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, 1999  primarily
consists of corporate debt securities.

Concentration of Credit Risk

         The  Company  invests   its  cash  in  debt  instruments  of  financial

                                       36
<PAGE>


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

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.

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.

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

Research and Development Costs

         Research and development costs are expensed as incurred.

Income Taxes

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

            Notes to Consolidated Financial Statements - (Continued)

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
which includes $127,500 of an assumed  incremental yield related to a beneficial
conversion  feature and $281,944 related to a 4% per annum stated value increase
in  security  (see Note 7),  divided by the  weighted  average  number of shares
issued and outstanding  during the period.  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, 1999,  1998 and 1997.  The
Company  has  certain  securities  outstanding  at  June  30,  1999  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 Income

         On  July  1,  1998,  the  Company  adopted  SFAS  No.  130,  "Reporting
Comprehensive  Income".  SFAS No. 130  establishes  standards  for reporting and
presentation of comprehensive  income (loss) and its components in a full set of
financial statements. Comprehensive income consists of net income (loss) and net
unrealized gains (losses) on securities and certain foreign exchange changes and
is presented in the  consolidated  statements  of operations  and  comprehensive
loss. The statement  requires only  additional  disclosures in the  consolidated
financial  statements;  it does not affect the Company's  financial  position or
results of operations. Prior year financial statements have been reclassified to
conform to the requirements of SFAS No. 130.

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

                                       38

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

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

Reclassification

         Certain 1997 and 1998 balances have been reclassified to conform to the
1999 presentation.

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,
1999 and 1998 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  $640,000  and  $568,000 at June 30, 1999 and 1998,  respectively.
Also  included are amounts  payable to various  legal  counsel of  approximately
$260,000 and $178,000, and accrued health insurance liabilities of approximately
$239,000 at June 30, 1999 and 1998.

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 June 27, 1996, the Company completed an equity financing pursuant to
Regulation S,  pursuant to which several  foreign  investors  purchased  200,000
shares of 5% Series D Convertible Preferred Stock (the "Series D Preferred") for
$10,000,000.  The  terms of the  transaction  allowed  the  investors,  at their
discretion,  to convert  the Series D  Preferred  into  shares of the  Company's
common stock during a 24-month period which began in June 1996, at a price equal
to 89% of the  average  market  price per  share  over a 20-day  trading  period
surrounding  the date of conversion.  As of June 30, 1998, all 200,000 shares of
Series D Preferred had been  converted  into  1,795,771  shares of the Company's
common stock.

         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 the 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 4% Series F  Convertible  Preferred  Stock  (the  "Series F Stock") to
several investors and received net proceeds of approximately  $12,349,800.  Each
share of Series F Stock has an initial stated value of $10,000,  which increases
at the rate of 4% per annum.  The increase in stated value of the Series F Stock
totaled $281,944 at June 30, 1999. The Series F Stock became  convertible at the
option  of the  investors,  in whole or in part,  on June 8,  1999,  subject  to
acceleration in certain instances. The number of shares of common stock issuable
upon  conversion  of each share of Series F Stock will be determined by dividing
the stated value of $10,000 plus an accretion of 4% per annum, by the conversion
price then in effect. The conversion price for the Series F Stock generally will
be the lesser of (a) 125% of the  average  market  price on June 7, 1999 and (b)
the average  closing bid price of the Company's  common stock during a specified
period  prior  to  conversion.  In  accordance  with the  terms of the  Series F
Preferred  Stock,  the Company was required to recognize an assumed  incremental
yield of $127,500  (calculated at the date of issuance and based on a beneficial
conversion  feature).  Such amount was amortized as a preferred  stock  dividend
over the six month period beginning with the date of issuance.

         Upon the occurrence of certain  events,  the Company may be required to
redeem the Series F Stock,  pay certain  penalties  and/or adjust the conversion
price. These events include the following:

         (a) If the Company  consolidates,  merges or  otherwise  combines  with
another entity and as a result the stockholders of the Company immediately prior
to such transaction do not retain sufficient voting power to elect a majority of
the board of  directors of the new or combined  entity,  then the holders of the
Series F Stock may  require the  Company to redeem  their  shares at a price per
share equal to the greater of (1) 125% of the stated  value of $10,000 per share
plus the  accretion of 4% per annum,  and (2) the value of the Common Stock that
would be  issuable  upon  conversion  of the  Series F  Stock.  However,  if the
consolidation,  merger  or other  business  combination  occurs as a result of a
proxy  solicitation which was not approved or recommended by the Company's Board
of Directors, then, if the holders exercise their redemption rights, the Company
may, in lieu of  redemption,  either (y) readjust the Initial Fixed Price to 80%
of the lower of (A) the lowest Variable Price during the period beginning on the
date such  solicitation is announced and ending on the date such solicitation is
consummated,  abandoned  or  terminated  or (B) the Initial  Fixed Price then in
effect,  or (z) pay a penalty of 1% per day of the stated  value of $10,000  per
share plus the accretion of 4% per annum for a maximum of 10 days in any 365-day
period.

            Notes to Consolidated Financial Statements - (Continued)

         (b) If at least a  specified  percentage  of the  holders of the Common
Stock  accept a  purchase,  tender or  exchange  offer,  then the holders of the
Series F Stock may  require the  Company to redeem  their  shares at a price per
share equal to the greater of (1) 125% of the stated  value of $10,000 per share
plus the  accretion of 4% per annum,  and (2) the value of the Common Stock that
would be  issuable  upon  conversion  of the  Series F Stock.  However,  if such
purchase,  tender or  exchange  offer was not  approved  or  recommended  by the
Company's  Board of Directors;  then, if the holders  exercise their  redemption
rights, the Company may, in lieu of redemption,  either (y) readjust the Initial
Fixed  Price to 80% of the lower of (A) the  lowest  Variable  Price  during the
period beginning on the date such offer is announced and ending on the date such
offer is  consummated,  abandoned or  terminated  or (B) the Initial Fixed Price
then in  effect,  or (z) pay a  penalty  of 1% per day of the  stated  value  of
$10,000 per share plus the accretion of 4% per annum for a maximum of 10 days in
any 365-day period.

         (c) If the Company  completes a sale of all or substantially all of its
assets, then the holders of the Series F Stock may require the Company to redeem
their shares at a price per share equal to the greater of (1) 125% of the stated
value of $10,000 per share plus the accretion of 4% per annum, and (2) the value
of the Common  Stock  that would be  issuable  upon  conversion  of the Series F
Stock.

         (d) If the  registration  statement  under the  Securities  Act of 1933
covering  the  resale  by  the  investors  of the  Common  Stock  issuable  upon
conversion of the Series F Stock ceases to be available to the investors for the
resale of their shares for more than 10  consecutive  days,  then the holders of
the Series F Stock may require the Company to redeem their shares at a price per
share equal to the greater of (1) 125% of the stated  value of $10,000 per share
plus the  accretion of 4% per annum,  and (2) the value of the Common Stock that
would be  issuable  upon  conversion  of the  Series F  Stock.  However,  if the
unavailability of the registration  statement is not the result of the Company's
failure to use its best efforts,  then, if the holders exercise their redemption
rights, the Company may, in lieu of redemption,  (y) pay a penalty of 1% per day
of the stated value of $10,000 per share plus the  accretion of 4% per annum for
a maximum of 15 days in any 365-day  period,  and (z) readjust the Initial Fixed
Price to 80% of the lowest  Variable  Price during the period  commencing on the
day the  registration  statement  became  unavailable  and ending on the day the
registration statement is again available for use.

         (e) If the  Common  Stock is  delisted  or  suspended  from the  Nasdaq
National  Market  for a period  of more  than five  consecutive  days,  then the
holders of the Series F Stock may require the Company to redeem  their shares at
a price  per  share  equal to the  greater  of (1) 125% of the  stated  value of
$10,000 per share plus the  accretion of 4% per annum,  and (2) the value of the
Common  Stock  that would be  issuable  upon  conversion  of the Series F Stock.
However,  if the Common Stock is delisted from the Nasdaq  National Market then,
if the holders  exercise their  redemption  rights,  the Company may, in lieu of
redemption, (y) readjust the Initial Fixed Price to 68.5% of the lowest Variable
Price during the period  commencing on the date of delisting and  continuing for
45 days  thereafter,  or (z) pay a penalty of 1% per day of the stated  value of
$10,000 per share plus the accretion of 4% per annum for a maximum of 15 days in
any 365-day period.

         Pursuant to its  agreement  with the  investors,  the Company  called a
Special Meeting of Stockholders on March 19, 1999, at which meeting stockholders
approved the issuance of any shares

                                       42

upon  conversion  of the Series F Stock in excess of 20% of the number of shares
of common  stock  the  Company  had  outstanding  on  December  9,  1998  (i.e.,
7,577,617)  in  accordance  with the rules and  regulations  of The Nasdaq Stock
Market, Inc.

         Each investor has agreed that if it engages in short sales transactions
or other hedging  activities during the 45 trading days immediately  preceding a
conversion date which involve, among other things, sales of shares of the Common
Stock, the investor will place its sale orders for common stock in the course of
such activities so as not to complete or effect any such sale on any trading day
during such  period at a price  which is lower than the lowest sale  effected on
such day by persons other than such investor or its affiliates.

         Because the market price of the Common Stock is subject to fluctuation,
the Company agreed, pursuant to the terms of a registration rights agreement, to
register  for resale by the  investors  at least 200% of the number of shares of
common stock that would be issuable if all the Series F Stock were  converted as
of the  date  of the  filing  of the  registration  statement  and,  thereafter,
maintain  the  registration  of at least  150% of the number of shares of common
stock that would be issuable if all the Series F Stock were then converted.  The
registration  statement  currently in effect covers  10,000,000 shares of common
stock. If the registration statement is insufficient to permit the resale by the
investors of all the common  shares  issuable  upon  conversion  of the Series F
Stock,  the  investors,  in  addition to any other  remedies,  have the right to
require the Company to redeem all or any  portion of the  remaining  outstanding
shares of Series F Stock (at a price  equal to the greater of 125% of the stated
value of $10,000 per share plus the  accretion  of 4% per annum and the value of
the Common Stock which would have been issued upon conversion) as well as pay to
them a penalty of $5 per share of Series F Stock for each day that sales  cannot
be made.  The  registration  statement  would not cover a  sufficient  number of
shares to permit the  investors to resell all the shares they could acquire upon
conversion  if the  Variable  Price  is less  than  approximately  $1.29  (which
threshold  will increase over time due to the 4% accretion to the stated value).
The Common Stock in the recent past has traded below this price.

         The Company has received a waiver,  dated  October 11,  1999,  from the
holders of the Series F Stock with respect to the rights  discussed above either
to require  redemption or to receive penalties  conditioned upon the Company (a)
filing a registration  statement,  on or before  November 11, 1999,  covering at
least 200% of the number of shares of common stock that would be issuable if all
the  Series  F  Stock  were  converted  as of  the  date  of the  filing  of the
registration  statement  and (b) having  such  registration  statement  declared
effective  on  or  before  December  11,  1999.   However,  if  failure  of  the
registration  statement to be declared effective by December 11, 1999 is not the
result of the Company's  failure to use its best  efforts,  then, if the holders
exercise their redemption  rights,  the Company may, in lieu of redemption,  (y)
pay a penalty  of 1% per day of the stated  value of $10,000  per share plus the
accretion  of 4% per annum for a maximum of 15 days in any 365-day  period,  and
(z) readjust the Initial Fixed Price to 80% of the lowest  Variable Price during
the period commencing on the day the registration  statement became  unavailable
for sale of all the shares and ending on the day the  registration  statement is
again available for use for sale of all the shares. In addition, notwithstanding
whether  or not the  Company  has  used its best  efforts,  if the  registration
statement is not filed by November  11, 1999 and declared  effective by December
11,  1999,  the  investors  also  will be  entitled  to the $5 per  day  penalty
(discussed above) accruing from the

first day that the Company was in breach of such registration obligation,  which
penalties  would be significant.  The Company  intends to file the  registration
statement on or before  November 11, 1999 and to use its best efforts to have it
declared  effective on or before December 11, 1999.  While the new  registration
statement  will cover a  significant  number of additional  shares,  the Company
would  not be  required  to issue  any  shares  which  are the  subject  of this
additional  registration  statement  unless  the  Variable  Price at the time of
conversion  is below $1.29  (increased  over time due to the 4% accretion to the
stated value).

         If the Company  were  required to redeem the Series F Stock or make any
of the  penalty  payments,  it may not have the  financial  ability to make such
payments.  Even if the  Company  did have the  financial  ability  to redeem the
Series F Stock or pay the required  penalties,  such payment could significantly
and adversely affect its financial condition and deplete its cash resources.

         As of  October  7,  1999,  22  shares  of the  Series F Stock  had been
converted into 193,994 shares of Common Stock. If all the remaining  outstanding
shares of Series F Stock had been  converted as of October 7, 1999,  the Company
would have been required to issue approximately  10,836,000 additional shares of
Common Stock.

         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
497,875  were still  available  at June 30, 1999 for future  grant.  At June 30,
1999,  2,857,375  shares of common  stock  were  reserved  for  possible  future
issuance  upon  exercise of stock  options  outstanding  and future stock option
grants.

         Pursuant to the terms of the 1992 Plan,  each  outside  Director of the
Company  who had  been a  Director  prior  to July 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.  On July 1, 1999,  80,000 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

         The fair value of each option granted during the three years ended June
30,  1999  is   estimated   on  the  date  of  grant  using  the   Black-Scholes
option-pricing model with the following  assumptions;  (I) dividend yield of 0%,
(II) expected term of 8 years, 8 years and 9.9 years, (III) expected  volatility
of 80% at June 30, 1999 and 42% at June 30, 1998 and 1997,  and (IV) a risk-free
interest rate of 5.06%,  5.57% and 6.50% for the years ended June 30, 1999, 1998
and 1997, respectively. The weighted average fair value at the date of grant for
options  granted during the years ended June 30, 1999,  1998 and 1997 was $1.26,
$2.55 and $4.91 per share, respectively.

         The pro forma effects on net loss allocable to common  shareholders and
related per share amounts for 1999, 1998 and 1997 may not be  representative  of
the pro forma effects in future years since (i)  compensation  cost is allocated
on a straight-line  basis over the vesting periods of the grants,  which extends
beyond the  reported  years,  (ii) and does not take into  effect  the  proforma
compensation  expense  related  to grants  made prior to the year ended June 30,
1996.

            Notes to Consolidated Financial Statements - (Continued)

         The valuation allowances for fiscal years 1999, 1998 and 1997 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,
1999, 1998 and 1997 include  $4,886,000,  $4,316,000 and $5,775,000  relating to
fiscal  years  1999,  1998 and 1997  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,  1999,  the  Company  has  available  net  operating  loss
carryforwards  for  federal  income  tax  reporting  purposes  of  approximately
$96,000,000,  which expire at various dates  between 2000 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.  The Company  made no  payments of federal or state  income
taxes during the years ended June 30, 1999, 1998 and 1997.

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 1999 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.

         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 December 31, 1999, 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.

         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 $45,000, $98,000 and $69,000 during the years ended June 30, 1999,
1998 and 1997,  respectively.  The Company also  provides  CMMI with  laboratory
materials  and  supplies  in  connection  with  research  conducted  in areas of
potential interest to the Company at no cost to CMMI.

         During each of the years ended June 30, 1999,  1998 and 1997, 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.  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 fiscal years 1999, 1998 and 1997.

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.

         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  ("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

                                       48

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

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 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").   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  Coulter's  interests  in IBC are  49.55%  and  43.45%
respectively. 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  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 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 (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,  based on the fair
value of  technology  transferred,  and has reflected his interest as a minority
interest on the  consolidated  financial  statements  as of June 30,  1999.  Dr.
Goldenberg also serves as Chairman of the Board of IBC.

11.    Commitments and Contingencies

         On  November  1,  1993,  the  Company and Dr. Goldenberg entered into a
five-year  employment  agreement (the "Agreement")  with an additional  one-year
assured renewal and thereafter  automatically  renewable for additional one-year
periods  unless  terminated  by either party as provided in the  Agreement.  Dr.
Goldenberg will receive an annual base salary of not less than $220,000, subject
to increases as determined by the Board of  Directors.  Effective  July 1, 1997,
the  Board of  Directors  increased  Dr.  Goldenberg's  annual  base  salary  to
$265,000. The Company has agreed to extend Dr. Goldenberg's employment agreement
for a  five-year  period  which  expires on October  31,  2003.  Dr.  Goldenberg
voluntarily reduced his annual base salary effective June 1999, from $265,000 to
$225,000.  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

                                       49

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,  1999,  1998 and 1997,  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 provides for an
option to purchase the  facility,  subject to certain  terms and  conditions  as
specified in the lease.  Rental expense related to this lease was  approximately
$425,000,   $425,000  and  $428,000  in  fiscal  years  1999,   1998  and  1997,
respectively.  Minimum lease  commitments  for  facilities  and equipment are as
follows for fiscal years ending:

                2000 ..............................$596,000
                2001 ............................. $441,000
                2002 ..............................$441,000
                2003 ..............................$446,000
                2004 ..............................$449,000

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

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, 1999, the Company's  indebtedness under this agreement was $372,227. In
the fiscal year ended June 30, 1999,  the Company paid $23,162 in interest under
this agreement.

13.      Geographic Segments

         Effective July 1, 1998, the Company adopted SFAS No. 131,  "Disclosures
about Segments of an Enterprise and Related  Information".  As discussed in Note
1, 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 1999,
revenues  from  one  major  customer  amounted  to  approximately  16% of  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,  1999 and  1998,  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, 1999.  These  consolidated  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects,  the financial position of Immunomedics,  Inc.
and  subsidiaries  as of June  30,  1999  and  1998,  and the  results  of their
operations and their cash flows for each of the years in the  three-year  period
ended  June  30,  1999,  in  conformity  with  generally   accepted   accounting
principles.
