                                    PART I

Item 1. Business.

The Company

   Endorex Corporation is a development stage drug delivery company,
incorporated in Delaware. Our core drug delivery technology, the Orasome(TM)
system, focuses on the oral and mucosal delivery of protein and peptide-based
drugs and vaccines previously delivered only by injection. The Orasome system
is licensed from the Massachusetts Institute of Technology ("MIT").

   In 1998 Endorex formed two drug delivery joint ventures with Elan
Corporation, plc ("Elan"), one of the world's leading drug delivery companies.
The purpose of the first joint venture, InnoVaccines Corporation
("InnoVaccines"), is to research, develop and commercialize novel delivery
systems for the human and veterinary vaccine markets.

   The second joint venture, Endorex Newco, Ltd. ("Newco"), focuses on the
utilization of the MEDIPAD(R) microinfusion pump, developed by Elan, to
deliver iron chelators for the treatment of a series of genetic blood
disorders known as iron overload disorders.

   Our headquarters is located north of Chicago, close to the headquarters of
several major pharmaceutical companies such as Abbott Laboratories, Baxter
International, Searle (the pharmaceutical division of Monsanto), and the U.S.
subsidiaries of two major Japanese pharmaceutical companies, Fujisawa and
Takeda Chemicals.

   This report contains forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended, and Section
27A of the Securities Act of 1933, as amended, and is subject to the safe-
harbors created by those sections. These forward-looking statements are
subject to significant risks and uncertainties, including those identified in
the "Risk Factors" section of this Form 10-KSB, which may cause actual results
to differ materially from those discussed in any forward-looking statements.
The forward-looking statements within this Form 10-KSB are identified by words
such as "believes," "anticipates," "expects," "intends," "may," "will" and
other similar expressions. However, these words are not the exclusive means of
identifying such statements. In addition, any statements that refer to

consider the various disclosures we make in this report and our other reports
filed with the SEC that attempt to advise interested parties of the risks and
factors that may affect our business.

Orasome Oral and Mucosal Drug Delivery System

   Endorex's fundamental platform technology resides in its potential ability
to convert injectable-only therapy into the patient-preferred format of oral
therapy. This conversion process includes encapsulating "fragile" protein
and/or peptide based drugs for oral delivery using proprietary patented
technology from MIT. Many vaccines and macromolecular drugs are exceptionally
fragile and thus cannot survive the digestive action of the gastrointestinal
("GI") tract. By employing the Orasome system, a specially engineered,
polymerized liposome-based technology for entrapment of protein or peptide-
based vaccines and drugs, many of these agents might be made orally available
at therapeutic levels. Endorex is developing core technology for a new
generation of vaccines that may be taken by mouth, thereby replacing painful
injections, and thereby increasing patient compliance. Other applications of
this technology under development at Endorex could enable preparation of oral
formulations of peptide hormones, such as insulin and human growth hormone,
other sensitive peptide drugs and proteins, and nucleic acids ("DNA").
Virtually all of these compounds are currently given to patients solely via
injection.

   The Orasome system represents a series of improvements in encapsulation
technology resulting in properties that we believe enable efficient uptake by
crucial cells in the gastrointestinal tract. Because of the unique

                                       1
<PAGE>

ability of these polymerized liposomes to withstand the activity of bile
salts, digestive enzymes, and gastric acids, this proprietary liposomal
technology may be utilized practically and commercially for the oral delivery
of many therapeutics.

   Orasomes encapsulate sensitive drugs and hold them within a membrane
envelope that is resistant to the environmental stress of the GI tract.
Orasomes can also be engineered to release contents in a controlled fashion
and to contain surface ligands (or biological "magnets") capable of targeting
specific receptors in the intestine and other tissues. By comparison,
conventional liposomes appear to be chemically and physically unstable and
tend to be unsuitable for oral delivery, because they degrade rapidly upon
introduction into the GI tract. If the encapsulated drug or vaccine is
released into this environment, the active material is destroyed and the
therapeutic effect negated. In vitro studies with orasomes have demonstrated
high stability under harsh conditions similar to conditions found in the human
intestinal tract, such as exposure to acidic pH, simulated bile salts, and
detergents.

   Liposomal formulations have been scaled up and manufactured commercially.
Examples of such formulations include the cancer drugs liposomal doxorubicin
and liposomal daunorubicin as well as the anti-fungal agent liposomal
amphotericin B, which have been approved by the Food and Drug Administration
("FDA") and are currently being marketed. Endorex is currently scaling up its
Orasome system for human clinical trials through its joint venture partner,
Elan.

   Endorex believes that the Orasome system as a platform technology satisfies
a number of criteria necessary for a successful drug delivery system,
including:

  --Flexibility for incorporation of numerous types of drugs and vaccines;

  --Stability of the drug or vaccine through the GI tract;

  --Enhanced mucosal uptake of the drug or vaccine;

  --Compatibility of the delivery system with current manufacturing
    methodology; and

  --No apparent toxicity of the orasomes in animal studies to-date.

Drug Delivery Development Status

   Endorex has demonstrated the bioavailability and bioactivity of using
orasomes for oral delivery of selected drugs in animal models as well as the
immunogenicity of oral vaccines in similar models. Orasomes have been used
successfully in animal models for oral delivery of human growth hormone
("hGH"). Endorex believes an oral version of hGH should provide product
differentiation along with the convenience and improved compliance that
accompanies oral delivery. Daily oral delivery should offer an attractive
alternative to daily injections or slow release formulations, particularly for
chronic therapies. Animal studies have shown that delivery of unencapsulated
hGH, or hGH in non-polymerized liposomes, does not result in a rise in serum
hGH, while hGH is detected in serum after oral delivery in orasomes.

   Endorex recently signed a research and option agreement with Novo Nordisk
A/S (a major European pharmaceutical company with a significant share of the
estimated $1.7 billion global market for hGH), to evaluate the commercial
attractiveness of Novo's brand of hGH delivered orally, Norditropin(R). They
plan to evaluate the Orasome system in several animal models. Novo Nordisk has
taken an exclusive option to license the Orasome technology for
Norditropin(R).

   During 2000, Endorex will also evaluate the Orasome system for oral
delivery of a DNA based product (vaccine).

Oral Delivery of Human and Veterinary Vaccines

   According to a Frost & Sullivan market research report on human vaccines,
the worldwide vaccine market is projected to reach $6 billion in 2000. There
is also a large and growing veterinary vaccine market.

                                       2
<PAGE>

   In order to participate in this attractive and large market with a new
delivery alternative, Endorex partnered with Elan in 1998 and established a
joint venture, InnoVaccines, for the research, development and
commercialization of oral and mucosal vaccines. In forming this joint venture,
Elan purchased equity securities of Endorex (common and preferred stock, as
well as warrants) for aggregate investments of $10 million. InnoVaccines
combines novel existing and future delivery systems from both companies for
the development of human vaccines.

   The joint venture has evaluated the Orasome system in animal models for its
potential to deliver a variety of vaccines, including tetanus, orally and by
nasal administration. Additionally, the company has demonstrated successful
encapsulation of a vaccine adjuvant in combination with the vaccine antigen.
No toxicological side effects have been seen in animal studies with orasomes.
During 2000, InnoVaccines plans to scale up the Orasome technology in
preparation for a clinical trial of its lead clinical candidate, an oral
tetanus vaccine. Additionally, the joint venture plans to evaluate the
feasibility and efficacy of an oral hepatitis B vaccine and an oral flu
vaccine in animal models.

   The Orasome technology for delivery of drugs and vaccines is the subject of
two MIT U.S. patents which have issued and four pending patents: one from MIT
and three filed by Endorex. In addition, the joint venture further extended
its fundamental oral vaccine intellectual property by acquiring an exclusive
worldwide license to the Southern Research Institute and University of
Alabama-Birmingham's portfolio of patents on oral microsphere delivery for
vaccines in 1999. This patent portfolio consists of six issued U.S. patents
and more than 40 related issued patents in Europe and in many countries
throughout the world.

Endorex/Elan MEDIPAD Drug Delivery System Joint Venture for Iron Chelators

   In October 1998, Endorex announced that it had established a second joint
venture with Elan whose purpose was the exclusive research, development and
commercialization of the MEDIPAD drug delivery system to deliver iron
chelators for the treatment of iron overload disorders. The most common cause
of this health problem is a type of genetic blood disorder. These diseases
include Cooley's anemia (beta-thalassemia) and sickle cell anemia.

   MEDIPAD is Elan's unique microinfusion pump designed for the subcutaneous
delivery of selected drugs that require continuous infusion via pump. Each
MEDIPAD is a low cost, disposable drug delivery device with an adhesive
backing. Its light weight enables it to be worn in a manner similar to a
transdermal patch. MEDIPAD is expected to replace conventional infusion pumps
that are expensive and cumbersome for the patient. Conventional pumps appear
to impede patient compliance. We believe MEDIPAD will improve patient
compliance.

   In February 2000, Endorex announced that the MEDIPAD iron chelator joint
venture has entered into an exclusive worldwide license, development, and
supply agreement with Schein Pharmaceutical, Inc. to develop and commercialize
iron chelating products using the MEDIPAD drug delivery system. Schein
Pharmaceutical will market this product in the United States.

Oncology Program

   On March 1, 2000, we announced that in spite of several active phase I and
II trials with our two oncology drugs, POH and ImmTher(R), Endorex has decided
to divest the oncology business in favor of focusing on the rapid expansion
and promise of our drug delivery business. Further development of the oncology
business would require a substantial step-up in investment in product
development and human resources at a time when we are facing a similar
requirement in our drug delivery business that has already attracted initial
partners. Oncology has been our focus for many years. However, to be a serious
participant in this highly competitive arena would require a significant
restructuring of our business and significantly higher financial resources. We
have already begun to pursue several alternatives for terminating our role in
this business early in 2000.

                                       3
<PAGE>

   Endorex's oncology program consists of two areas of cancer therapy:
immunotherapy and natural chemotherapy.

Immunotherapy Program

   Endorex's immunomodulator, ImmTher(R), works by activating macrophages,
cells that specifically recognize and destroy cancer cells. ImmTher(R) is
currently being evaluated in a randomized phase II (efficacy) trial as an
adjunct therapy, following surgery and chemotherapy, for the treatment of bone
cancer in children and young adults. The initial therapy for this type of
cancer is often surgery (including limb amputation). However, residual cancer
cells remaining after surgery metastasize to the liver or lungs and patients
rarely survive more than a few years. ImmTher(R) is being tested for its
usefulness in treating micrometastases with a goal of increasing the life of
these children and young adults. The trial is being conducted at the two
leading cancer centers in the U.S., Memorial Sloan Kettering in New York and
M.D. Anderson Cancer Center in Houston. Endorex has received Orphan Drug
designation for ImmTher(R) by the FDA for two types of bone cancer, Ewings
sarcoma and osteogenic sarcoma.

Natural Chemotherapy

   POH is a synthetic compound that is a member of a new class of anti-cancer
agents, monoterpenes, which have shown anti-tumor and preventative activity
against a wide range of tumor types in preclinical studies at non-toxic dose
levels. POH was developed by Dr. Michael Gould and his collaborators at the
University of Wisconsin-Madison, with the support of the National Cancer
Institute.

   Monoterpenes are natural compounds produced by plants and are found in
commonly consumed fruits and vegetables, and have multiple cellular effects
including the modulation of the cellular levels of growth factors and their
receptors. Monoterpenes selectively inhibit cell growth in a wide variety of
rodent tumors and human cancer cell lines and also act to induce programmed
cell death (apoptosis).

   Wisconsin Genetics, Inc. ("WGI"), a majority-owned Endorex subsidiary, was
founded to develop new therapies for the prevention and treatment of cancer.
Patents covering the use of POH in the treatment of cancer have been licensed
for development by WGI from Wisconsin Alumni Research Foundation ("WARF").
WARF, a non-profit organization, is the office designated to receive and
license new discoveries made by the University of Wisconsin-Madison
researchers.

   In June 1999, WGI completed development of a new oral formulation of POH
and filed an Investigational New Drug ("IND") application. The new formulation
significantly reduces the number of pills a patient needs to take daily and
should enhance overall patient compliance during the treatment. In September
1999, we commenced the first Endorex-sponsored POH trial of the new
formulation, a phase I (safety) human clinical trial commenced at the
University of Wisconsin-Madison Comprehensive Cancer Center. The National
Cancer Institute ("NCI") continues to sponsor phase II clinical trials in
breast, prostate and pancreatic cancer. During 1999, two phase II NCI-
sponsored trials for ovarian and colorectal cancer were closed due to lack of
objective response. All of the NCI-sponsored phase II trials use the initial
formulation of POH developed by the NCI. Additional phase II clinical trials
with POH in other types of cancer, such as brain cancer and different types of
leukemia, are being considered.

Government Regulation

   Prior to marketing, each of our products must undergo an extensive
regulatory approval process conducted by the FDA and applicable agencies in
other countries. Testing, manufacturing, commercialization, advertising,
promotion, export and marketing, among other things, of our proposed products
are subject to extensive regulation by government authorities in the United
States and other countries. All products must go through a series of tests,
including advanced human clinical trials, which the FDA is allowed to suspend
as it deems necessary.

                                       4

Patents and Other Proprietary Rights

   We rely on patent rights, trade secrets and nondisclosure agreements to
establish and protect our proprietary rights to our technologies. Despite
these precautions, it may be possible for unauthorized third parties to
utilize our technology or to obtain and use information that we regard as
proprietary. The laws of some foreign countries do not protect our proprietary
rights in processes and products to the same extent as the laws of the United
States.

   Endorex currently has the following patent portfolio in the United States:
(1) Endorex has three issued patents, (2) Orasomal has two patents issued, (3)
InnoVaccines has licensed a series of patents from Southern Research
Institute, 6 of which have issued in the U.S., and (4) WGI has licensed the
rights to three patents issued to WARF. In addition, we have more than 50
foreign issued patents, as well as several foreign patent applications
pending.

Research and Development Expense

   Research and development expenditures were approximately $2.0 million for
the year ended December 31, 1999 and the year ended December 31, 1998.

Employees

   As of March 1, 2000 we had fifteen full-time employees, including 5 Ph.D.s,
and 4 masters-level employees.

   Endorex has recruited seasoned managers with considerable experience in the
pharmaceutical industry and utilizes a Scientific Advisory Board, certain
members of which are prominent researchers and academics in their fields.
Michael Rosen, the company's President/CEO, joined Endorex in 1996. Prior to
joining Endorex, Mr. Rosen held senior executive positions at Monsanto, Pfizer
and Bristol-Myers Squibb. Robert Brey, Ph.D., Vice President of Research and
Development, has prior experience with American Home Products' vaccine
division. David Franckowiak, Chief Financial Officer, spent eleven years with
PricewaterhouseCoopers LLP prior to joining Endorex in 1997. Frank C. Reid
joined Endorex in February 2000 as Vice President of Finance and Corporate
Development. He has extensive experience in banking and management consulting,
including nineteen years with Bank of America/Continental Bank in senior
executive positions.

   Endorex's board of directors includes CEO's and senior management of other
publicly traded biotechnology companies with extensive pharmaceutical company
expertise, and a member of Elan's senior management team.

   Endorex has assembled an expert Scientific Advisory Board for its Orasome
technology. Drug Delivery Advisory Board Co-Chairman, Dr. Robert Langer,
recognized as a leading expert on drug delivery technology, is a member of
three National Academies (Sciences, Medicine and Engineering), holds 265
patents and has authored over 500 articles. Dr. Langer is a Professor of
Biomedical and Chemical Engineering and is co-inventor of the Orasome
technology. Advisory Board Co-Chairman, Dr. Henry Brem, is a Professor of
Neurology, Ophthalmology and Oncology at Johns Hopkins University. Drs. Langer
and Brem have significant continued involvement with Endorex as advisors,
consultants and shareholders.

                                 RISK FACTORS

If we cannot obtain additional funding, our product development and
commercialization efforts may be reduced or discontinued.

   We will require additional funding to sustain our research and development
efforts, provide for future clinical trials, and continue our operations until
we are able to generate sufficient revenue from the sale and/or licensing of
our products. We cannot be certain whether we will be able to obtain required
additional funding on terms satisfactory to us, if at all. In addition, we
have expended, and will continue to expend, substantial funds on the
development of our product candidates and for clinical trials. We currently
have commitments to expend additional funds for the development of the Orasome
oral delivery system, the MEDIPAD infusion pump, license contracts, severance
arrangements, employment agreements, and consulting agreements. If we are
unable to raise additional funds when necessary, we may have to reduce or
discontinue development, commercialization or clinical testing of some or all
of our product candidates or enter into financing arrangements on terms that
we would not otherwise accept.

We have had significant losses and anticipate future losses.

   We are a development stage company, have experienced significant losses
since inception and have a significant accumulated deficit. We expect to incur
significant additional operating losses in the future and expect cumulative
losses to substantially increase due to expanded research and development
efforts, preclinical studies and clinical trials. All of our products are
currently in development, preclinical studies or clinical trials, and we have
not generated significant revenues from product sales. We do not expect to
generate significant product revenues in the next year. There can be no
guarantee that we will ever generate product revenues sufficient to become
profitable or to sustain profitability.

We are dependent on our joint ventures with Elan Corporation and any future
joint ventures.

   Our strategy for research, development and commercialization of certain of
our products is to rely on arrangements with corporate partners. As a result,
our products are dependent upon the success of third parties in performing
preclinical studies and clinical trials, obtaining regulatory approvals,
manufacturing and marketing. In connection with our two joint ventures with
Elan, we are obligated to fund research and development activities in
proportion to our ownership interest in each joint venture, currently 80.1% of
each joint venture, based on the research and development plan and budget that
we mutually agree upon with Elan. If we do not have sufficient resources to
meet our funding obligations under the two Elan joint ventures, we may have to
terminate the venture prior to commercialization or renegotiate the terms of
the joint venture with Elan, or our interest in the venture may be diluted. We
intend to pursue additional collaborations in the future, however, the terms
available may not be acceptable to us and the collaborations may not be
successful. In addition, the amount and timing of resources that our
collaborators devote to these activities are not within our control.

Problems in product development may cause our cash depletion rate to increase.

   We have limited experience with clinical trials and if we encounter
unexpected difficulties with our operations or clinical trials, we may have to
expend additional funds, which would increase our cash depletion rate. Our
ability to manage expenses and our cash depletion rate are keys to the
continued development of product candidates and the completion of ongoing
clinical trials. Our cash depletion rate will vary substantially from quarter
to quarter as we fund non-recurring items associated with clinical trials,
product development, patent legal fees and consulting fees.

Our product development and commercialization efforts may not be successful.

   Our product candidates, which have not received regulatory approval, are
generally in the early stages of development. If the initial results from any
of the clinical trials are poor, those results will adversely effect our

                                       6
<PAGE>

ability to raise additional capital, which will affect our ability to continue
full-scale research and development for our oral delivery technology. In
addition, product candidates resulting from our research and development
efforts, if any, are not expected to be available commercially for several
years, if at all. Our products, if approved, may not be immediately used by
doctors unfamiliar with our product's application in the treatment of cancer.
As with any new drug, doctors may be inclined to continue to treat patients
with conventional therapies, in most cases chemotherapy, rather than new
alternative therapies. We or our marketing partner may be required to
implement an aggressive education and promotion plan with doctors in order to
gain market recognition, understanding and acceptance of our products. Any
such effort may be time consuming and might not be successful. Accordingly, we
cannot guarantee that our product development efforts, including clinical
trials, or commercialization efforts will be successful or that any of our
products, if approved, can be successfully marketed.

Our technology and products may prove ineffective or harmful, or be too
expensive to market successfully.

   Our future success is significantly dependent on our ability to develop and
test workable products for which we will seek approval from the FDA to market
to certain defined patient groups. The products we are currently developing
will require significant additional laboratory and clinical testing and
investment for the foreseeable future. Although we are optimistic that we will
be able to complete development of one or more products, our proposed products
may not prove to be effective in clinical trials or they may cause harmful
side effects during clinical trials. In addition, our product candidates, if
approved, may prove impracticable to manufacture in commercial quantities at a
reasonable cost and/or with acceptable quality. Any of these factors could
negatively affect our financial position and results of operations.

Our dependence on a limited number of suppliers may negatively impact our
ability to complete clinical trials and market our products.

   Prior to commercial distribution of any of our products, if approved, we
will be required to identify and contract with a commercial supplier. We
cannot guarantee that these suppliers will be able to qualify their facilities
under regulations imposed by the FDA or that they will be able to label and
supply us with drugs in a timely manner, if at all. Accordingly, any change in
our existing or future contractual relationships with, or an interruption in
supply from, any third-party service provider or supplier could negatively
impact our ability to complete clinical trials and to market our products, if
approved.

We do not have a sales force to market our products.

   If and when we receive approval from the FDA for our initial product
candidates, the marketing of these products will be contingent upon our
ability to either license these products or enter into marketing agreements
with partner companies or our ability to recruit, develop, train and deploy
our own sales force. We currently intend to sell our products in the United
States and internationally in collaboration with one or more marketing
partners. However, we presently have no agreements for the licensing or
marketing of our product candidates, and we cannot assure you that we will be
able to enter into any such agreements in a timely manner or on commercially
favorable terms, if at all. Additionally, we do not presently have a sales
force, or possess the resources or experience necessary to market any of our
product candidates, if and when they are approved. Development of an effective
sales force requires significant financial resources, time and expertise. We
cannot assure you that we will be able to obtain the financing necessary to
establish such a sales force in a timely or cost effective manner, if at all,
or that such a sales force will be capable of generating demand for our
product candidates, if and when they are approved.

We maintain only limited product liability insurance and may be exposed to
claims if our insurance coverage is insufficient.

   The manufacture and sale of our products involves an inherent risk of
product liability claims. We currently have product liability insurance with
limits of liability of $10 million. Because product liability insurance is

                                       7
<PAGE>

expensive and difficult to obtain, we cannot assure you that we will be able
to maintain existing insurance or obtain additional product liability
insurance on acceptable terms or with adequate coverage against potential
liabilities. Our inability to obtain sufficient insurance coverage on
acceptable terms or to otherwise protect against potential product liability
claims in excess of our insurance coverage, if any, could negatively impact
our financial position and results of operations.

We may not be able to compete with our competitors in the biotechnology
industry.

   The biotechnology industry is intensely competitive, subject to rapid
change and sensitive to new product introductions or enhancements. Virtually
all of our existing competitors have greater financial resources, larger
technical staffs, and larger research budgets than we have, as well as greater
experience in developing products and conducting clinical trials. Our
competitors in the vaccine delivery field include Aviron, which is developing
a nasal flu vaccine that is in phase III, BioVector, which is in phase II
trials with an intranasal flu vaccine and another major vaccine, specialized
biotechnology firms, universities, and governmental agencies. Our competitors
in the liposomal formulation field include The Liposome Company, NexStar and
Sequus. Our competitors in the field of the oral delivery of drugs include
Emisphere, which has recently started Phase III trials for oral heparin and
phase I trials with oral calcitonin, and is in preclinical development with
oral hormones; Unigene, which has an oral calcitonin product in phase I; and
Protein Delivery which has an oral insulin in early clinical trials in Europe
and the U.S. In addition, there may be other companies which are currently
developing competitive technologies and products or which may in the future
develop technologies and products which are comparable or superior to our
technologies and products. Accordingly, we cannot assure you that we will be
able to compete successfully with our existing and future competitors or that
competition will not negatively affect our financial position or results of
operations in the future.

We may not be successful if we are unable to obtain and maintain patents and
licenses to patents.

   Our success depends, in large part, on our ability to obtain and maintain a
proprietary position in our products through patents, trade secrets and orphan
drug designations. We have been granted several United States patents and have
submitted several United States patent applications and numerous corresponding
foreign patent applications, and have also obtained licenses to patents or
patent applications owned by other entities. However, we cannot assure you
that any of these patent applications will be granted or that our patent
licensors will not terminate any of our patent licenses. We also cannot
guarantee that any issued patents will provide competitive advantages for our
products or that any issued patents will not be successfully challenged or
circumvented by our competitors. Further, the laws of certain countries may
not protect our proprietary rights to the same extent as U.S. law. We are
dependent upon our license of oral delivery technology from MIT, and licenses
from Elan in connection with our two joint ventures with Elan. We cannot
assure you that the technology underlying such licenses will be profitable, or
that we will be able to retain licenses for such technologies or that we will
obtain patent protection outside the United States. To the extent that we rely
on trade secret protection and confidentiality agreements to protect our
technology, others may develop similar technology, or otherwise obtain access
to our findings or research materials embodying those findings. The
application of patent law to the field of biotechnology is relatively new and
has resulted in considerable litigation. There is a substantial risk in the
rapidly developing biotechnology industry that patents and other intellectual
property rights held by us could be infringed by others or that products
developed by us or their method of manufacture could be covered by patents
owned by other companies. Although we believe that our patents and our
licensors' patents do not infringe on any third party's patents, we cannot be
certain that we can avoid litigation involving such patents or other
proprietary rights. Patent and proprietary rights litigation entails
substantial legal and other costs, and we may not have the necessary financial
resources to defend or prosecute our rights in connection with any litigation.
Responding to, defending or bringing claims related to patents and other
intellectual property rights may require our management to redirect our human
and monetary resources to address these claims and may take years to resolve.

Our product development and commercialization efforts may be reduced or
discontinued due to difficulties or delays in clinical trials.

   We may encounter unanticipated problems, including development,
manufacturing, distribution, financing and marketing difficulties, during the
product development, approval and commercialization process. Our product
candidates may take longer than anticipated to progress through clinical
trials. In addition, patient enrollment in the clinical trials may be delayed
or prolonged significantly, thus delaying the clinical trials and causing
increased costs. If we experience any such difficulties or delays, we may have
to reduce or discontinue development, commercialization or clinical testing of
some or all of our product candidates.

Our product development and commercialization efforts may be reduced or
discontinued due to delays or failure in obtaining regulatory approvals.

   We will need to do substantial additional development and clinical testing
prior to seeking any regulatory approval for commercialization of our product
candidates. Testing, manufacturing, commercialization, advertising, promotion,
export and marketing, among other things, of our proposed products are subject
to extensive regulation by governmental authorities in the United States and
other countries. The testing and approval process requires substantial time,
effort and financial resources and we cannot guarantee that any approval will
be granted on a timely basis, if at all. At least initially, we intend, to the
extent possible, to rely on licensees to obtain regulatory approval for
marketing our products. The failure by us or our licensees to adequately
demonstrate the safety and efficacy of any of our product candidates under
development could delay, limit or prevent regulatory approval of the product,
which may require us to reduce or discontinue development, commercialization
or clinical testing of some or all of our product candidates. Companies in the
pharmaceutical and biotechnology industries have suffered significant setbacks
in conducting advanced human clinical trials, even after obtaining promising
results in earlier trials. Furthermore, the United States Food & Drug
Administration may suspend clinical trials at any time on various grounds,
including a finding that the subjects or patients are being exposed to an
unacceptable health risk. Also, even if regulatory approval of a product is
granted, such approval may entail limitations on the indicated uses for which
it may be marketed. Accordingly, we may experience difficulties and delays in
obtaining necessary governmental clearances and approvals to market our
products, and we may not be able to obtain all necessary governmental
clearances and approvals to market our products.

Our products, if approved, may not be commercially viable due to health care
changes and third-party reimbursement limitations.

   Recent initiatives to reduce the federal deficit and to change health care
delivery are increasing cost-containment efforts. We anticipate that Congress,
state legislatures and the private sector will continue to review and assess
alternative benefits, controls on health care spending through limitations on
the growth of private health insurance premiums and Medicare and Medicaid
spending, price controls on pharmaceuticals, and other fundamental changes to
the health care delivery system. Any such changes could negatively impact the
commercial viability of our products, if approved. Our ability to successfully
commercialize our product candidates, if and when they are approved, will
depend in part on the extent to which appropriate reimbursement codes and
authorized cost reimbursement levels of such products and related treatment
are obtained from governmental authorities, private health insurers and other
organizations, such as health maintenance organizations. In the absence of
national Medicare coverage determination, local contractors that administer
the Medicare program, within certain guidelines, can make their own coverage
decisions. Accordingly, there can be no assurance that any of our product
candidates, if approved and when commercially available, will be included
within the then current Medicare coverage determination or the coverage
determination of state Medicaid programs, private insurance companies and
other health care providers. In addition, third-party payers are increasingly
challenging the prices charged for medical products and services. Also, the
trend toward managed health care and the growth of health maintenance
organizations in the United States may all result in lower prices for our
products, if approved and when commercially available, than we currently
expect. The cost containment measures that health care payers and providers
are instituting and the effect of any health care changes could

                                       9
<PAGE>

negatively affect our financial performance, if and when one or more of our
products are approved and available for commercial use.

Our operations and financial performance could be negatively affected if we
cannot attract and retain key personnel.

   Our success is dependent, in part, upon a limited number of key executive
officers and technical personnel, including Michael S. Rosen, our President
and Chief Executive Officer, David G. Franckowiak, our Chief Financial
Officer, Dr. Robert N. Brey, our Vice President of Research and Development,
and Frank C. Reid, our Vice President of Finance and Corporate Development. We
also believe that our future success will depend largely upon our ability to
attract and retain highly skilled research and development and technical
personnel. We face intense competition in our recruiting activities, including
competition from larger companies with greater resources. We cannot assure you
that we will be successful in attracting or retaining skilled personnel. The
loss of certain key employees or our inability to attract and retain other
qualified employees could negatively affect our operations and financial
performance.

Our stock price is highly volatile and our common stock is thinly traded.

   The market price of our common stock, like that of many other development-
stage public pharmaceutical and biotechnology companies, has been highly
volatile and may continue to be so in the future. Factors such as disclosure
of results of preclinical and clinical testing, adverse reactions to products,
governmental regulation and approvals, and general market conditions may have
a significant effect on the market price of the common stock and our other
equity securities. Since it commenced trading on the American Stock Exchange
on August 6, 1998, our common stock has been thinly traded. We cannot
guarantee that a more active trading market will develop in the future.

Investors may suffer substantial dilution.

   Endorex has a number of agreements or obligations that may result in
dilution to investors. These include:

  .  warrants to purchase 2,162,162 shares of common stock at $2.54375 per
     share, subject to adjustment, issued in connection with the October 1997
     Private Placement;

  .  warrants for the purchase of 230,770 shares of common stock at $10.00
     per share held by Elan;

  .  warrants to purchase 66,668 shares of common stock at $2.54375 per
     share, subject to adjustment, held by the Aries Master Fund and the
     Aries Domestic Fund, L.P.;

  .  conversion rights and dividend rights of preferred stock held by Elan,
     consisting of 92,973 shares of Series B Convertible Preferred Stock
     ($8.0 million original liquidation value) bearing an 8% cumulative
     payment-in-kind dividend and convertible at liquidation value into
     common stock at $7.50 per share, subject to adjustment, and 91,218
     shares of Series C Exchangeable Convertible Preferred Stock ($8.4
     million original liquidation value) bearing a 7% cumulative payment-in-
     kind dividend and which is exchangeable for part of Endorex's interest
     in the second joint venture or convertible at liquidation value into
     common stock at $9.00 per share;

  .  options to purchase approximately 1.6 million shares of common stock
     outstanding to participants in our stock option plan with a weighted
     average exercise price of approximately $3.00;

  .  anti-dilution rights under the above warrants and preferred, which can
     permit purchase of additional shares and/or at lower prices under
     certain circumstances. To the extent that anti-dilution rights are
     triggered, or warrants or conversion rights are exercised, our
     stockholders will experience substantial dilution and the Company's
     stock price may decrease.

                                      10

Future sales of common stock by our existing stockholders could adversely
affect our stock price.

   The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of common stock in the market, or the
perception that these sales could occur. These sales also might make it more
difficult for us to sell equity securities in the future at a time and at a
price that we deem appropriate.

We have not paid cash dividends.

   We have never paid cash dividends on our common stock and we do not
anticipate paying any dividends in the foreseeable future. We currently intend
to retain earnings, if any, for the development of our business.

We have certain interlocking relationships that may present potential
conflicts of interest.

   Lindsay A. Rosenwald, M.D., is the Chairman and sole stockholder of
Paramount Capital Asset Management, Inc. ("PCAM"), Paramount Capital, Inc.
("Paramount"), and Paramount Capital Investment LLC ("PCI"), a merchant
banking and venture capital firm specializing in biotechnology companies. PCAM
is the investment manager of The Aries Master Fund, a Cayman Island exempted
company, and the general partner of each of the Aries Domestic Fund, L.P. and
the Aries Domestic Fund II, L.P., each of which is a significant stockholder
of Endorex. In addition, certain officers, employees and/or associates of
Paramount and/or its affiliates own securities in subsidiaries of Endorex. In
the regular course of its business, PCI identifies, evaluates and pursues
investment opportunities in biomedical and pharmaceutical products,
technologies and companies. Generally, Delaware corporate law requires that
any transactions between Endorex and any of its affiliates be on terms that,
when taken as a whole, are substantially as favorable to us as those then
reasonably obtainable from a person who is not an affiliate in an arms-length
transaction. Nevertheless, neither such affiliates nor PCI is obligated
pursuant to any agreement or understanding with us to make any additional
products or technologies available to us. We do not expect and you should not
expect, that any biomedical or pharmaceutical product or technology identified
by such affiliates or PCI in the future will be made available to us. In
addition, certain of the current officers and directors of Endorex or any
officers or directors of the company hereafter appointed may from time to time
serve as officers, directors or consultants of other biopharmaceutical or
biotechnology companies. There can be no assurance that such other companies
will not have interests in conflict with us.

Certain directors and stockholders have significant influence.

   Our directors, executive officers and principal stockholders and certain of
their affiliates have the ability to influence the election of directors and
most other stockholder actions. In particular, pursuant to a placement agency
agreement, so long as 50% of the shares sold in our October 1997 private
placement remain outstanding and subject to contractual rights described in
the subscription agreement, we may not do any of the following without the
placement agent's prior approval:

  .  issue or increase the authorized amount or alter the terms of any
     securities of the Company senior to, or on parity with, the private
     placement shares with respect to voting, liquidation or dividends,

  .  alter the Company's charter documents in any manner that would adversely
     affect the relative rights, preferences, qualifications, limitations or
     restrictions of the private placement shares or of certain contractual
     rights described in the subscription agreements,

  .  incur indebtedness in excess of $1.0 million,

  .  incorporate or acquire any subsidiaries, and

  .  enter any transactions with affiliates of the Company.

   In addition, our Board of Directors cannot exceed seven persons without the
prior written consent of the placement agent. These arrangements may
discourage or prevent any proposed takeover of Endorex, including

                                      11
<PAGE>

transactions in which stockholders might otherwise receive a premium for their
shares over the then current market prices. Such stockholders may influence
corporate actions, including influencing elections of directors and
significant corporate events.

Item 2. Facilities.

   Endorex's executive offices and research and development center are located
in a leased facility of approximately 7,500 square feet in Lake Forest,
Illinois, near Chicago. The lease expires on December 31, 2003. We believe
that our current leased facilities are sufficient to meet our needs for the
foreseeable future and that suitable additional space will be available if and
as needed.

Item 3. Legal Proceedings.

   The Company is not a party to any legal proceedings.

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

   There were no matters submitted to a vote of security holders in the fourth
quarter of 1999.

Item 5. Market for Common Equity and Related Stockholder Matters.

   As of August 6, 1998, our common stock started trading on the American
Stock Exchange under the symbol "DOR." Prior to that, quotations for Endorex's
common stock appeared on the "pink sheets" published by the National
Quotations Bureau, Inc. and on the "Bulletin Board" of the National
Association of Securities Dealers, Inc. The following table sets forth the
high and low bid quotations, as provided by the National Quotation Bureau,
Inc., for our common stock during the period January 1, 1998 through August 5,
1998. The table sets forth the high and low closing prices, as provided by the
American Stock Exchange, for the period from August 6, 1998 through March 1,
2000. The amounts represent inter-dealer quotations without adjustment for
retail markups, markdowns or commissions and do not represent the prices of
actual transactions.

</TABLE>

   As of December 31, 1999, we had approximately 1,100 stockholders of record.
We currently intend to retain any earnings for use in our business and do not
anticipate paying any cash dividends in the foreseeable future.

   In connection with a senior line of credit agreement entered into by
Endorex with two of our major stockholders, Aries Domestic Fund, L.P. and The
Aries Fund, on May 19, 1997, we granted warrants to purchase an aggregate of
66,668 shares of common stock at an initial exercise price equal to the
offering price of Endorex's Private Placement (as defined below), subject to
adjustment under certain circumstances. The warrants are exercisable until May
19, 2002.

   Pursuant to a private placement (the "Private Placement") of common stock,
we issued and sold an aggregate of 8,648,718 shares of common stock to
accredited investors on July 16, October 10 and October 16, 1997, in
consideration of an aggregate amount of $20,000,000. Our net proceeds, after
deducting commissions and expenses of Paramount Capital, Inc., which acted as
the placement agent for the Private Placement (the "Placement Agent"), were
$17,400,000.

   In connection with the Private Placement, we issued and sold to the
Placement Agent and/or its designees, warrants (the "Placement Warrants") to
purchase up to an aggregate of 864,865 shares of common stock. In connection
with the execution of a financial advisory agreement, dated October 16, 1997,
between Endorex and the Placement Agent, we issued and sold to the Placement
Agent warrants (the "Advisory Warrants") to purchase up to an aggregate of
1,297,297 shares of common stock. The Placement Warrants and the Advisory
Warrants are exercisable until April 16, 2003, at an exercise price of
$2.54375 per share, subject to adjustment under certain circumstances.

   On January 21, 1998, Endorex formed a joint venture, InnoVaccines
Corporation, with Elan. In connection with the agreement, we issued and sold
to Elan International Services, Ltd. ("EIS"), 307,692 shares of Endorex common
stock and warrants to purchase an aggregate of 230,770 shares of common stock
in consideration of an aggregate amount of $2.0 million. The warrants are
exercisable until January 20, 2007, at an exercise price of $10.00 per share.
In addition, we issued and sold to EIS 80,100 shares of Endorex Series B
Convertible Preferred

                                      13
<PAGE>

Stock at a price of $100 per share. The Series B Preferred Stock is voting and
pays an 8% annual cumulative in-kind dividend. The shares can be converted to
common stock based upon their liquidation value, currently at $7.50 per share,
subject to adjustment.

   On October 21, 1998, we formed a second joint venture with Elan, Endorex
Newco, Ltd. In connection with the new agreement, Endorex issued and sold to
EIS 84,105 shares of Series C Exchangeable Convertible Preferred Stock
("Series C Preferred"), at a price of $100 per share. The Series C Preferred
Stock is non-voting and pays a 7% annual cumulative in-kind dividend. The
shares can be exchanged for common stock in the joint venture or converted to
Endorex common stock at $9.00 per common share.

Item 6. Management's Discussion and Analysis or Plan of Operations.

   The following "Discussion and Analysis" provides information that we
believe is relevant to an assessment and understanding of our results of
operation and financial condition. You should read this analysis in
conjunction with our audited consolidated financial statements and notes
thereto. This report contains statements of a forward-looking nature relating
to future events or our future financial performance. These statements are
only predictions and actual events or results may differ materially. In
evaluating such statements, you should carefully consider the various factors
identified in this report, which could cause actual results to differ
materially from those indicated from any forward-looking statements, including
those set forth in "Risk Factors" on this Annual Report Form 10-KSB.

Material Changes in Results of Operations

   Net loss for the twelve months ended December 31, 1999 of $7.5 million
decreased approximately $14.3 million as compared to the $21.8 million loss
recorded for the twelve months ended December 30, 1998. Reduction in equity
losses from Endorex's two joint ventures with Elan accounted for substantially
all of the reduction in consolidated net loss from 1998 to 1999. For 1999,
equity losses from joint ventures were $2.9 million as compared with $17.1
million for 1998. The 1998 equity losses include our 80.1% share of the
aggregate $20.0 million license fees paid by the joint ventures to Elan to
acquire two technologies: 1) an oral delivery technology for vaccines, and 2)
a medical device called MEDIPAD for delivery of certain drugs for treatment of
life-threatening diseases.

   Research and development expenditures for the year ended December 31, 1999
were $2.0 million, approximately the same as compared to the year ended
December 31, 1998. The increased effort devoted to the InnoVaccines joint
venture versus other Endorex activities offset the reduction related to
expenses we incurred in 1998 to transfer the laboratory facilities and
scientific personnel to Lake Forest, IL from Fargo, ND.

   Excluding the impact of the license fees paid to Elan in 1998, equity in
losses from joint ventures increased $1.8 million or 166% from 1998 to 1999.
Elan and Endorex each funded research and development related to InnoVaccines
equally from the inception of the joint venture through March 31, 1999, in
accordance with the agreement between Elan and Endorex. As of April 1, 1999,
Endorex and Elan fund future joint venture expenditures in proportion to our
respective ownership levels, therefore Endorex includes 80.1% of the joint
ventures results. The current year equity loss also includes $0.4 million for
Endorex's portion of InnoVaccines' acquisition of an exclusive worldwide
license and intellectual property for proprietary oral microsphere delivery
technology for human and veterinary vaccines. The license encompasses a
portfolio of over 50 patents acquired from Vaxcel, Inc., which was the
previous exclusive licensee for this technology from the Southern Research
Institute and the University of Alabama-Birmingham Research Foundation. The
current year equity loss includes $400,500 reflecting Endorex's 80.1% share of
losses relating to the second joint venture.

   General and administrative expenses for the year ended December 31, 1999
decreased $0.5 million, or 13%, to $3.0 million as compared to $3.5 million
for the year ended December 31, 1998. The decrease was mainly

                                      14
<PAGE>

due to a $0.3 million reduction in amortization of fair value of warrants
issued in connection with the financial advisory agreement with Paramount
Capital, Inc. The warrants, which were amortized over a two-year period, were
fully amortized by the end of the third quarter of 1999. Excluding this
amortization, legal expenses decreased approximately $160,000 as compared to
1998. During 1998, we had additional legal expenses related to the initiation
of Endorex's listing on the American Stock Exchange, effective August 6, 1998
under our new symbol DOR, joint venture activity, and private placement
activities.

   Interest income for the year ended December 31, 1999 decreased
approximately $0.3 million as compared to the year ended December 31, 1998 due
to a depletion of cash and marketable securities utilized in research and
development activities. Endorex is a development stage enterprise and expects
no significant revenue from the sale of products in the near future.

Plan of Operation and Financial Condition

   Endorex continues to progress preclinical development of the Orasome
delivery system for the oral delivery of vaccines and drugs. Development
includes ongoing work with Elan and several major medical and academic
institutions for vaccines and key hormones such as insulin and human growth
hormone. A new patent for this technology was issued in February 2000. During
2000, we anticipate that InnoVaccines will begin to scale up an oral tetanus
vaccine to take into human clinical trials. Additionally the joint venture
will develop prototype oral hepatitis B and flu vaccines and evaluate them in
animal models during 2000. Such new vaccines have been made possible by
InnoVaccines's advances in delivery technology that include safe and effective
adjuvants and site specific targeting. "Targeting" vaccines to the correct
sites in the gastrointestinal tract or the nasal passage gets the antigen to
the right place; otherwise, antigens are lost and are ineffective. Adjuvants
boost the overall immune response to the antigen, creating a higher level of
immunization. This element is critical in persons with diminished immune
systems, such as the elderly, where many vaccines are much less effective.
InnoVaccines combines novel existing and future delivery systems of the two
companies for the development of human vaccines, a $6 billion market that is
projected to increase to $10 billion by 2003, as well as for the growing
veterinary vaccine market.

   During 1999 collaborative development efforts began for our second joint
venture with Elan, Endorex Newco, Ltd., established for the commercialization,
research and development of two iron chelator drugs using the MEDIPAD
technology. The MEDIPAD system is a small, disposable drug delivery system,
which combines a microinfusion pump with the convenience of patch technology.
We expect to initiate clinical trials during 2000 with MEDIPAD in one iron
chelator drug through the joint venture, and our recently announced agreement
with Schein Pharmaceutical, Inc.

   Endorex recently signed a research and option agreement with Novo Nordisk
A/S (a major pharmaceutical company with a significant share of the estimated
$1.7 billion global market for hGH), to evaluate the commercial attractiveness
of Novo's brand of hGH delivered orally, Norditropin(R). They plan to evaluate
the Orasome system in several animal models. Novo Nordisk has taken an
exclusive option to license the Orasome technology for Norditropin(R).

   During 2000, Endorex will also evaluate the Orasome system for oral
delivery of a DNA vaccine.

   On March 1, 2000, we announced that in spite of several active phase I and
II trials with our two oncology drugs, POH and ImmTher(R), Endorex has decided
to divest the oncology business in favor of focusing on the rapid expansion
and promise of our drug delivery business. Further development of the oncology
business would require a substantial step-up in investment in product
development and human resources at a time when we are facing a similar
requirement in our drug delivery business that has already attracted initial
partners. Oncology has been our focus for many years. However, to be a serious
participant in this highly competitive arena would require a significant
restructuring of our business and significantly higher financial resources. We

   On December 31, 1999 and December 31, 1998, we had cash, cash equivalents,
and marketable securities of $8.5 million and $13.2 million, respectively, and
working capital of $6.9 million and $12.6 million, respectively, exclusive of
deferred costs. Our current level of activities requires the expenditure of
approximately $400,000 per month, including costs associated with the joint
ventures. We believe that our current cash resources will be sufficient to
support currently planned operations for the next two years. However, we
intend, from time to time in the future, to seek to expand our research and
development activities into other technologies and/or products that we either
may license from other persons or develop. Any such activities may require the
expenditure of funds not presently available. We also may seek to obtain funds
from possible future public or private sales of our securities or other
sources. See "Risk Factors--If we cannot obtain additional funding, our
product development and commercialization efforts may be reduced or
discontinued."

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)



1. Operations

   Basis of Presentation--Endorex Corporation and Subsidiaries was
incorporated in January 1987 as ImmunoTherapeutics, Inc, a wholly owned
subsidiary of BiologicalTherapeutics, Inc. ("BTI"). BTI was incorporated on
December 19, 1984 and commenced operations on February 15, 1985 [inception
date]. On March 30, 1987 BTI was merged into Endorex. Our financial statements
include the accounts of our predecessor, BTI, for all periods presented. In
October 1996 Endorex formed its first subsidiary, Orasomal Technologies, Inc.
("Orasomal"), and in July 1997, we formed a second subsidiary, Wisconsin
Genetics, Inc. ("WGI").

   Nature of Business--Endorex Corporation is a development-stage drug
delivery company. Our core drug delivery technology focuses on oral/mucosal
delivery of drugs and vaccines previously delivered only by injection. The
Company's Orasome system utilizes technology licensed from MIT to develop the
oral/mucosal delivery of vaccines, proteins and peptides.

   In 1998 Endorex formed two joint ventures with Elan Corporation, plc, one
of the world's leading drug delivery companies. The purpose of the first joint
venture, InnoVaccines, is to research, develop, and commercialize novel
delivery systems for the human and veterinary vaccine markets. The second
joint venture, Newco, focuses on the utilization of the MEDIPAD microinfusion
pump, developed by Elan, to deliver iron chelators for the treatment of a
series of genetic blood disorders known as iron overload disorders.

2. Summary of Significant Accounting Policies

   Principles of Consolidation--The consolidated financial statements include
Endorex and its subsidiaries, Orasomal and WGI. Intercompany accounts and
transactions have been eliminated. We account for the joint ventures by
recognizing Endorex's portion of the joint venture losses as Equity in losses
from joint ventures.

   Segment and Geographic Information -- Endorex operates exclusively in the
biotechnology drug delivery industry. We are currently in the development
stage and do not have any revenues, or any segregation of assets relating to
products or business entities. All development work is performed in the United
States. During 1999, we made operating decisions based upon product and market
potential and collaborative agreements and did not utilize specific operating
results to manage the business. Therefore, we do not have reportable operating
segments as defined by Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information."

   Cash and Cash Equivalents--Cash equivalents are comprised of certain highly
liquid investments with maturity of three months or less when purchased.

   Marketable Securities--Marketable securities are comprised of high-grade
commercial paper and short-term government agency notes that have maturities
ranging from six to twelve months from the purchase date. The fair value of
marketable securities classified as available for sale approximates the
carrying value of these assets due to the short maturity of the instruments.

   Office and Lab Equipment and Leasehold Improvements--Office and lab
equipment is stated at cost. Depreciation is computed on a straight-line basis
over five years. Leasehold improvements are amortized utilizing the straight-
line method over the term of the lease. Depreciation expense was $138,582 and
$75,934 for the periods ended December 31, 1999 and 1998, respectively.

   Research and Development Costs--Expenditures for research and development
activities are charged to operations as incurred. Previously reported research
and development expenses related to our first year funding

                                     F-10

                       (A Development Stage Enterprise)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

of InnoVaccines have been reclassified in the accompanying 1998 consolidated
statement of operations to Equity in losses from joint ventures to conform to
our 1999 presentation of expenditures. The reclassification did not impact
previously reported net loss or deficit accumulated during the development
stage.

   Patent Issuance Costs--The cost of patents is accumulated during the
approval process. Patents granted are amortized on a straight-line basis over
the remaining legal life of the patent or the estimated remaining economic
life. When a patent is not granted, or the process is terminated, the
accumulated cost is charged to operations.

   Common Stock Dividend--Common stock dividends are reflected as a charge to
accumulated deficit, using the fair market value method computed with the
closing price as of the day before the declaration date.

   Investment in Joint Ventures--We own 80.1% of each of the joint ventures
with Elan as of December 31, 1999. Each joint venture is governed by a joint
development and operating agreement which provides that both Elan and Endorex
must approve all major transactions, research and development plans, and
budgets. Therefore, Endorex records its share of the joint ventures'
expenditures as Equity in losses from joint ventures.

   Impairment of Long-Lived Assets--In the event that facts and circumstances
indicate that the cost of any long-lived assets may be impaired, an evaluation
of recoverability would be performed. If an evaluation is required, the
estimated future undiscounted cash flows associated with the asset would be
compared to the asset's carrying amount to determine if a write-down to market
value or discounted cash flow is required.

   Concentrations of Credit Risk--Financial instruments that potentially
subject us to concentrations of credit risk primarily are limited to cash,
cash equivalents, and marketable securities. Cash is primarily invested in
money market mutual funds managed by investment banks approved by the Board of
Directors. Our marketable securities investments consist of high-grade
commercial paper and short-term government agency notes.

   Use of Estimates--While preparing financial statements in conformity with
generally accepted accounting principles, our management makes 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
reporting period. Actual results could differ from those estimates.

   Risk and Uncertainties--We are subject to risks common to companies in the
biotechnology industry, including, but not limited to, litigation, product
liability, development by ourselves or our competitors of new technological
innovations, dependence on key personnel, protections of proprietary
technology, and compliance with FDA regulations.

3. Joint Ventures

   In 1998 Endorex formed the two joint ventures with Elan as follows:

InnoVaccines Corporation

   InnoVaccines was established in January 1998 pursuant to agreements between
Endorex and Elan. At the time of closing, we issued to Elan International
Services, Ltd. ("EIS") 307,692 shares of Endorex common stock and a six-year
warrant to purchase an additional 230,777 shares of Endorex common stock at an
exercise price of $10.00 per share for an aggregate purchase price of $2.0
million. In addition, EIS purchased $8.0 million of Endorex Series B
convertible preferred stock, which is convertible into Endorex common stock at
a price of $7.50 per share, subject to adjustment. The Series B convertible
preferred stock pays an 8% annual in-kind dividend.

                                     F-11
<PAGE>

                              ENDOREX CORPORATION
                       (A Development Stage Enterprise)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   InnoVaccines is initially owned 80.1% by Endorex and 19.9% by Elan. It
licensed certain technology from Elan and certain other technology from
Orasomal. Endorex and Elan invested $8.0 and $2.0 million in the joint
venture, respectively.

   At the time of closing, InnoVaccines paid Elan an initial $10.0 million
license payment. Elan may receive future milestones and royalties based on the
joint venture's performance. Since the technology did not yet represent a
commercial product, the joint venture recorded an expense in the first quarter
of 1998 for the initial license fee. We recorded our $8.0 million share of
that expense and simultaneously recorded Elan's purchase of $8.0 million of
Endorex Series B convertible preferred stock.

   Orasomal sub-licensed to InnoVaccines oral vaccine rights to its
proprietary Orasome polymerized liposome technology exclusively licensed from
MIT. In consideration of the license, Orasomal may receive milestone payments
and royalties.

   Elan and Endorex each funded research and development related to
InnoVaccines equally from the inception of the joint venture through March 31,
1999, in accordance with the agreement between Elan and Endorex. Those
expenditures by Endorex aggregated $1.1 million and $0.4 million for the year
ended December 31, 1998 and 1999, respectively, and are included in Equity in
losses from joint ventures. As of April 1, 1999, Endorex and Elan fund future
joint venture expenditures in proportion to our respective ownership levels.
Accordingly, Endorex and Elan each invoice InnoVaccines for activities
performed on behalf of the venture. During the period April 1, 1999 through
December 31, 1999, Endorex incurred research and development expenditures
aggregating $1.1 million related to the joint venture. Endorex billed the
joint venture $1.6 million during that period related to this research and
development activity. Endorex has a net due to joint venture of $0.6 million
as of December 31, 1999 relating to InnoVaccines, which represents the
difference between Endorex's funding obligations to the venture and receivable
from the venture for activities performed. In addition, Elan has agreed to
lend Endorex up to $2.5 million, restricted to Endorex's funding obligations
for the joint venture. During 1999, the joint venture acquired certain rights
to licenses, aggregating $870,000, which were immediately recorded as expense
of the joint venture, as such technology did not yet represent a commercial
product. Elan and Endorex agreed to fund these licensing expenditures equally.

Endorex Newco, Ltd.


   Newco was established in October 1998 pursuant to agreements between
Endorex and Elan. At the time of closing, Endorex and EIS purchased $8.4
million and $2.1 million of Newco's common stock, respectively. In addition,
Elan purchased $8,410,500 of Endorex Series C exchangeable convertible
preferred stock ("Series C Preferred"). The Series C Preferred is exchangeable
at Elan's option for an additional 30.1% ownership interest of Newco's common
stock, or it may be converted into Endorex's common stock at a price of $9.00
per share. The Series C Preferred pays a 7% annual in-kind dividend.

   Newco is initially owned 80.1% by Endorex and 19.9% by EIS. At the time of
closing, Newco paid Elan an initial $10.0 million license payment. Elan may
receive future milestones and royalties based on Newco's performance. Since
the technology did not yet represent a commercial product, Newco recorded an
expense in the fourth quarter of 1998 for the initial license fee. We also
recorded our $8.0 million share of that expense and simultaneously recorded
EIS's $8.4 million purchase of Series C Preferred.

   In consideration of the license fee, Newco has obtained an exclusive
worldwide license to the MEDIPAD drug delivery system developed by Elan with
two drugs. Newco is now focusing on development of the first of those drugs,
iron chelators, for the treatment of a series of genetic blood disorders known
as iron overload

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

disorders. MEDIPAD is a lightweight, microinfusion pump, which combines the
simplicity of a patch with the extensive delivery capabilities of an infusion
pump.

   During 1999, Newco's research and development activities were funded from
working capital. As of December 31 1999, Elan and Endorex invoiced activities
totaling approximately $500,000. Endorex has a net due to joint venture of
$350,000 as of December 31, 1999 relating to Newco, which represents the
difference between Endorex's funding obligations to the venture and receivable
from the venture for activities performed. During 2000 and 2001, Elan and
Endorex are required to fund Newco expenditures according to their respective
ownership interests. However, Endorex may require Elan to lend up to $4.8
million, pursuant to a convertible note, to fund our portion of the joint
venture's research and development expenses.

Unaudited Condensed Financial Statements for Unconsolidated Joint Ventures

   Condensed, unaudited financial statement information of the joint ventures

6. Lines of Credit

   On December 31, 1998, Endorex obtained a $750,000 equipment financing line
with Finova Technology Financing, Inc. ("Finova"). As of December 31, 1999, we
had used approximately $456,000 to finance equipment and leasehold
improvements related to the Lake Forest Research and Development Center.
Interest rates for each draw are based upon a base interest rate of 7.4%, plus
an index rate equivalent to the highest yield as published in The Wall Street
Journal of three-year United States Treasury Notes two days prior to the loan
draw. The index rates for the first and second draws were 4.75% and 5.83%,
respectively, resulting in an aggregate interest rate of 12.15% and 13.23%,
respectively. Draws are payable in monthly installments over a period of 48
months, which currently amounts to approximately $11,000 per month. Finova
filed security interest in the assets. In addition, the agreement is subject
to certain terms and covenants, including the right of Finova to call the loan
in the event of materially adverse financial conditions. We estimate the fair
value of the line of credit to be approximately the carrying value based upon
borrowing rates currently available to us for borrowings with similar terms.

   On May 19, 1997, Endorex entered into a senior line of credit agreement
with The Aries Funds, two of our major stockholders, pursuant to which we
could borrow up to $500,000 (the "Bridge Loan"). During 1997, we paid the
outstanding principal and interest on the Bridge Loan. In partial
consideration of the Bridge Loan, Endorex granted warrants to purchase an
aggregate of 66,668 shares of common stock at an initial exercise price equal
to $2.54 per share. The warrant exercise price and the number of shares of
common stock that the warrants can be used to purchase are subject to
adjustment in certain circumstances. The warrants are exercisable until May
19, 2002.

7. Stockholders' Equity

   Private Placement--Pursuant to a Private Placement, Endorex issued and sold
an aggregate of 8,648,718 shares of common stock on July 16, October 10 and
October 16, 1997 to certain accredited investors. The aggregate proceeds of
these issuances were $20 million and the net proceeds to Endorex, after
deducting commissions and expenses, were $17.2 million.

   In connection with the Private Placement, we issued warrants to purchase
864,865 shares of Endorex common stock at an exercise price of $2.54375 per
share to Paramount Capital, Inc., the Placement Agent ("Paramount") and
certain of its affiliates and employees. The estimated fair value at the
warrants' grant date was $2.1 million, which we recorded as a reclassification
of additional paid-in capital. We also executed a financial advisory agreement
with Paramount. In connection with the financial advisory agreement, we issued
warrants to purchase 1,297,297 shares of Endorex common stock at an exercise
price of $2.54375 per share to certain employees of Paramount. The estimated
fair value at the warrants' grant date was $3.16 million, which was recorded
as a deferred cost and amortized to expense over two years, the term of the
agreement. The warrants currently are exercisable and expire on April 16,
2003.

   Common Stock Dividend--The terms of the Private Placement also included 5%,
semi-annual dividends payable in additional shares of common stock based on
the number of shares held as of the record date, including previous dividend
distributions.

   The first and second semi-annual common stock dividends were payable to
holders of stock with dividend rights as of the record date of April 16, 1999
and October 16, 1999, respectively. We distributed the first and second
dividends on June 1, 1999 and November 16, 1999, respectively. Semi-annual
common stock dividends continue to be payable through October 16, 2002.

                       (A Development Stage Enterprise)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   The stock dividends were reflected as a charge to accumulated deficit,
using the fair market value method computed with the closing price as of the
day before the declaration date.

   Net Loss Per Share--Pursuant to Statement of Financial Accounting Standards
("SFAS") No. 128 "Earnings per Share," we presented earnings per share on the
Consolidated Statement of Operations in accordance with SFAS No. 128 for the
current and prior periods. As operations resulted in a net loss for all
periods presented, diluted earnings per share are the same as basic earnings
per share due to the anti-dilutive effect of potential dilutive common shares,
including warrants discussed above and stock options discussed in Note 8.

8. Stock Based Compensation

   The Amended and Restated 1995 Omnibus Plan ("the Plan") is intended to
promote Endorex's interests by providing eligible persons with the opportunity
to acquire a proprietary interest, or otherwise increase their proprietary
interest, in the Company as an incentive for them to remain in the service of
the Company. The Plan is divided into three separate equity programs: 1) the
Discretionary Option Grant Program, under which eligible persons may, at the
discretion of the Plan Administrator, be granted options to purchase shares of
common stock, 2) the Salary Investment Option Grant Program, under which
eligible employees may elect to have a portion of their base salary invested
each year in options to purchase shares of common stock, 3) the Automatic
Option Grant Program, under which eligible non-employee Board members will
automatically receive options at periodic intervals to purchase shares of
common stock, and 4) the Director Fee Option Grant Program, under which non-
employee Board members may elect to have all, or any portion, of their annual
retainer fee otherwise payable in cash applied to a special option grant.

   The terms of the options, including vesting periods, are determined by the
Compensation Committee of the Board of Directors in accordance with the Plan.
Options generally vest over four years. No one person participating in the
Plan may receive options and separately exercisable stock appreciation rights
for more than 750,000 shares of Common Stock per calendar year.

   We elected the disclosure-only option under Statement of Financial
Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation" and accordingly account for stock options per the terms of
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees." If instead, compensation expense for stock options had been
determined based upon the fair value at the grant date, according to the terms
of SFAS No. 123, our net loss would have increased by approximately $0.4
million, or $.03 per share, and $1.3 million, or $0.12 per share, for 1999 and
1998, respectively. Net loss and net loss per share would have increased as
follows:

</TABLE>

   The weighted average fair value of options granted with an exercise price
equal to the fair market value of the stock was $1.45 and $5.46 for 1999 and
1998, respectively.

   For purposes of estimating the fair value of options according to SFAS 123,
we estimated the fair value of each option grant as of the date of the grant
using the Black-Scholes option-pricing model. The following weighted-average
assumptions were used: dividend yield 0%, volatility of 139% and 149-226%,
expected life of four (4) years, and risk-free interest rates as of the date
of grant ranging from 5.05%-6.2% and 5.36-6.06% for 1999 and 1998,
respectively.

   Option activity for the periods ended December 31, 1999 and 1998 was as

9. Income Taxes

   At December 31, 1999, we had a usable net operating loss carryforward of
approximately $15.9 million after limitations based on ownership. If not
utilized to offset future taxable income, this carryforward will expire in
years 2007 to 2019. Pursuant to SFAS No. 109, we have deferred taxes as of
December 31, 1999 consisting of the following:

      <S>                                                          <C>

</TABLE>

   Due to the uncertainty that we will generate income in the future
sufficient to fully or partially utilize these carryovers, a valuation
allowance of $11,185,359 has been established to offset the deferred tax
asset. This represents an increase of $1.9 million over the valuation
allowance at December 31, 1998. Under the Internal Revenue Code certain stock
transactions including sales of stock and the granting of options to purchase
stock, could limit the amount of net operating loss carry forwards that may be
utilized on an annual basis to offset taxable income in future periods. If
utilization is limited by such transactions the net operating loss carry
forwards may expire before they are utilized.

10. Leases

   Endorex leases its executive offices and research facilities under
operating leases, which provide for annual minimum rent and additional rent
based on increases in operating costs and real estate taxes. Rental expense
was $83,153 during 1999 and $95,522 during 1998.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Endorex Corporation (A
Development Stage Enterprise):

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of stockholders' equity (deficit) and
of cash flows, present fairly, in all material respects, the financial
position of Endorex Corporation and its subsidiaries (a development stage
enterprise) at December 31, 1999, and the results of their operations and
their cash flows for the years ended December 31, 1999 and 1998, and for the
period cumulative from inception (February 15, 1985) to December 31, 1999, in
conformity with accounting principles generally accepted in the United States.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements
based on our audits. We conducted our audits of these statements in accordance
with auditing standards generally accepted in the United States, which require
that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

7.2  If determined by the PROJECT TEAM, ENDOREX JV shall be responsible for
     filing and maintaining a MAF (or equivalent) for the SYSTEM with the RHA
     (or equivalent) in such countries in the TERRITORY as the MANAGEMENT
     COMMITTEE shall select from time to time. ENDOREX JV shall use reasonable
     endeavours in filing and maintaining each MAF with the RHA in the TERRITORY
     as swiftly as practicable. The cost of filing and maintaining such MAF for
     the SYSTEM shall be shared equally between ENDOREX JV and SCHEIN.

7.3  At its expense, SCHEIN shall be responsible for the filing and maintaining
     all required ANDAs and DEVICE REGULATORY APPLICATIONS in respect of the
     COMPOUND and PRODUCT respectively, with the RHAs in the TERRITORY. SCHEIN
     shall use reasonable endeavours in prosecuting each required ANDA and
     DEVICE REGULATORY APPLICATION to approval by the RHA as swiftly as
     practicable.

7.4  SCHEIN shall notify ENDOREX JV of the date of submission of any ANDA or
     DEVICE REGULATORY APPLICATION in any country of the TERRITORY and shall
     also notify ENDOREX JV of any ANDA APPROVAL or DEVICE REGULATORY APPROVAL
     as soon as is reasonably possible following said approval.

7.5  SCHEIN will be the holder of the ANDA APPROVAL and DEVICE REGULATORY
     APPROVAL for the COMPOUND and PRODUCT respectively, in the TERRITORY,
     provided however, that in the event that a DEVICE REGULATORY APPROVAL is
     granted for the SYSTEM alone, such DEVICE REGULATORY APPROVAL shall be the
     property of ENDOREX JV. In such event, ENDOREX JV shall provide SCHEIN with
     reference rights to such DEVICE REGULATORY APPROVAL mutatis mutandis with
     the provisions of Clause 7.6 below.

7.6  SCHEIN will permit ENDOREX JV, or ENDOREX JV's licensees, without charge,

     connection with ENDOREX JV's commercial arrangements otherwise than in
     relation to the PRODUCT for the FIELD, and in connection with the PRODUCT
     for the FIELD in any countries which cease to be part of the TERRITORY; and
     in the TERRITORY following termination of this Agreement.

                                       21
<PAGE>

7.7  SCHEIN shall submit to ENDOREX JV a quarterly report, for every calendar
     quarter prior to the marketing of the PRODUCT within [*****]of the end of

     approvals.

7.9  SCHEIN shall provide ENDOREX JV with access to all DEVICE REGULATORY
     APPROVALS to enable ENDOREX JV to exercise its rights and fulfil its
     obligations hereunder.

7.10  [*****].

7.11  Subject to the express representations and warranties set out in this
      Agreement, it is hereby acknowledged that there are inherent uncertainties
      involved in the registration of pharmaceutical products and medical
      devices with the RHA in relation to achieving the PROJECT SYSTEM
      SPECIFICATIONS and/or PRODUCT SPECIFICATIONS, filing and maintaining the
      MAF, and obtaining the ANDA APPROVAL and/or DEVICE REGULATORY APPROVAL and
      such uncertainties form part of the business risk involved in undertaking
      the form of commercial collaboration outlined in this Agreement.
      Accordingly, ENDOREX JV and SCHEIN shall have no liability to the other as
      a result of any failure of the PRODUCT to successfully achieve the PROJECT
      SYSTEM SPECIFICATIONS or PRODUCT SPECIFICATIONS, or the MAF, ANDA APPROVAL
      or DEVICE REGULATORY APPROVAL of the RHA, unless such failure is due to a
      Party's gross negligence or intentional misconduct.

     commensurate with that put forth by other pharmaceutical companies of
     similar size to SCHEIN for prescription products of similar market
     potential for similar audience size/type in the TERRITORY, and (2)
     sufficient with respect to the potential for the TERRITORY to fully exploit
     the market potential for the PRODUCT with the understanding that
     advertising, sales, marketing and promotional expenses in the [*****] after

     After the initial [*****] year period all dedicated direct marketing and
     selling expenses for the PRODUCT shall be decided upon by the MANAGEMENT
     COMMITTEE at least 6 months in advance. At least 3 months prior to the
     planned launch of the PRODUCT in the USA, SCHEIN will outline to the
     MANAGEMENT COMMITTEE the structure of the promotional activities to be
     carried out by SCHEIN for the period up to the first commercial sale of the

     and subsequent to the launch of a PRODUCT communicate with the MANAGEMENT
     COMMITTEE regarding its objectives for and performance of such PRODUCT in
     the USA and in all of the other countries of the TERRITORY. At meetings of
     the MANAGEMENT COMMITTEE, SCHEIN shall report on the ongoing sales
     performance of the PRODUCT in the TERRITORY, including marketing
     approaches, educational campaigns, promotional and advertising materials
     and campaigns, sales plans, pricing and results, performance against
     competitors, its objectives for the PRODUCT and its plans for the next year
     of the Agreement. In addition the MANAGEMENT COMMITTEE shall review the
     quarterly PROFIT statements and in particular the calculation of PROFIT,
     NSP and the deductible items listed in the definition of NSP.

8.3  Subject to the trademark licensing procedures set forth in Clause 3.6
     above, SCHEIN shall control and be responsible for the content and format
     of the promotional campaign to be submitted to the RHA, but shall inform
     ENDOREX JV thereof and provide to ENDOREX JV a copy of such submissions,
     which shall be subject to the confidentiality obligations herein. To the
     extent required by the laws, rules and regulations of the RHA in the
     applicable country of the TERRITORY, SCHEIN shall use reasonable efforts to
     obtain approval by the RHA of the promotional campaign for the PRODUCT.

8.4  Within [*****] of the EFFECTIVE DATE, the MANAGEMENT COMMITTEE shall agree
     in good faith upon a schedule for the commercialisation of the PRODUCT in
     such countries of the TERRITORY outside of the USA as the MANAGEMENT
     COMMITTEE shall determine. Such schedule shall include but not be limited
     to the target dates for appointing a SUBLICENSEE, filing the DEVICE
     REGULATORY APPLICATION and for securing DEVICE REGULATORY APPROVAL for the
     PRODUCT in such countries of the TERRITORY.

8.5  SCHEIN shall diligently pursue the commercialisation of the PRODUCT and

     market and promote the PRODUCT in the USA, and in doing so, shall use the
     same level of effort as with other similar products of similar sales
     potential which it markets. SCHEIN covenants that it shall not use the
     PRODUCT as a "loss leader" in its marketing programs and shall at all times
     use its reasonable efforts in marketing the PRODUCT.

8.6  SCHEIN shall submit to ENDOREX JV for ENDOREX JV's information, copies of
     all trade packaging, cartons and labels and other printed materials
     (Materials") which SCHEIN proposes at any time to use in relation to the
     sale of the PRODUCT provided always that the provisions of this Clause 8.6
     shall be without prejudice to the obligations and responsibilities of
     SCHEIN under Clauses 8.3 and 15.7 and SCHEIN shall indemnify and hold
     harmless ENDOREX JV from and against all claims, damages, losses,
     liabilities and expenses to which ENDOREX JV may become liable relating to
     such Materials, provided however that SCHEIN shall have no liability to the
     extent that such claims, damages, losses, liabilities and expenses arise
     from information which was provided to SCHEIN by ENDOREX JV in accordance
     with the terms of this Agreement. Unless ENDOREX JV reasonably objects to
     the use of any such materials within 14 days of receipt for information
     purposes, SCHEIN shall be entitled to proceed to use such trade packaging,
     cartons and labels and other printed materials in connection with the sale
     of the PRODUCT provided however, that in no event shall such materials
     contain any statement which may have a damaging or harmful effect on the
     commercialisation of the PRODUCT and/or the goodwill of ENDOREX JV in the
     TERRITORY.

8.7  To the extent permitted by law, the materials referred to in Clause 8.6
     shall include due acknowledgement that the PRODUCT is licensed from ENDOREX
     JV.

8.8  To the extent permitted by law, ENDOREX JV shall be entitled to mark or
     have marked all patent number(s) in respect of the ENDOREX JV PATENTS or

     otherwise reasonably communicate to the trade the existence of any ENDOREX
     JV PATENTS for the countries within the TERRITORY in such a manner as to
     ensure compliance with, and enforceability under, applicable laws.

8.9  SCHEIN shall effect the first full scale commercial launch of the PRODUCT
     in the USA as soon as reasonably practicable but in any event within
     [*****] in the USA, provided that ENDOREX JV has supplied SCHEIN with
     LAUNCH STOCKS ordered in accordance with the terms of this Agreement.  With

                       CLAUSE 9 - SUPPLY OF THE PRODUCT

9.1  Save as otherwise provided in this Agreement, ENDOREX JV's designee shall
     produce and supply to SCHEIN its entire requirements of the PRODUCT.
     ENDOREX JV shall supply the PRODUCT  solely and exclusively  to SCHEIN in
     the TERRITORY and SCHEIN will purchase the PRODUCT exclusively from ENDOREX
     JV in the TERRITORY.

9.2  The PRODUCT shall be supplied to SCHEIN by ENDOREX JV in such form as may
     be agreed by the Parties during the PROJECT.  ENDOREX JV shall deliver the
     PRODUCT to SCHEIN and/or any party designated by SCHEIN in proper packaging
     so as to permit safe storage and transport and to maintain the
     sterilisation of the PRODUCT. ENDOREX JV shall be responsible at its sole
     expense, for furnishing all operations, labour, supervision, equipment,
     tools, machinery, and facilities necessary to manufacture the PRODUCT in
     accordance with the SYSTEM SPECIFICATIONS, PRODUCT SPECIFICATIONS and
     DEVICE REGULATORY APPROVALS; provided however, that in all events, SCHEIN
     shall be responsible for the supply of the COMPOUND for the PRODUCT in
     accordance with Clause 10.

9.3  ENDOREX JV shall deliver the PRODUCT within 120 days of the receipt of a
     firm purchase order therefor (120 days in the case of LAUNCH STOCKS).  The
     delivery time for the PRODUCT shall be agreed upon by the Parties.

9.4  No later than 12 months prior to the filing of the first REGULATORY
     APPLICATION in the TERRITORY, SCHEIN shall provide ENDOREX JV with a
     forecast of SCHEIN's requirements for the PRODUCT for the 18 month period
     following the first anticipated REGULATORY APPROVAL in the TERRITORY.  The
     said forecast will be updated quarterly until the first REGULATORY APPROVAL
     in the TERRITORY.  Except as otherwise provided herein, all forecasts made
     hereunder shall be made to assist ENDOREX JV in planning its production and
     SCHEIN in planning marketing and sales.  Such forecasts shall not be
     binding purchase orders, and shall be without prejudice to SCHEIN's
     subsequent firm purchase orders for the PRODUCT in accordance with the
     terms of this Agreement.

9.5  Prior to the commencement of commercial manufacture of the PRODUCT, SCHEIN
     shall provide a rolling 18 months forecast for the period beginning on the
     first day of the relevant calendar month.  The format of such 18 months
     forecasts shall be comprised of a 12 monthly forecast together with 2
     quarterly forecasts.  The first calendar quarter of such 18 months forecast
     shall be a binding purchase commitment of SCHEIN.  In addition to the
     obligation of SCHEIN regarding rolling 18 month forecasts outlined herein,
     SCHEIN shall provide ENDOREX JV with rolling 3 years' forecasts on 1 August
     of each year of this Agreement.

     Subject to the agreement of the PROJECT TEAM, the calendar quarterly
     forecasts (other than for LAUNCH STOCKS) shall not increase or decrease
     from one quarter to

     the next by more than [*****] in terms of volume of the PRODUCT ordered.
     Notwithstanding the foregoing, ENDOREX JV will use its reasonable efforts
     to fulfil SCHEIN's requirements in excess of forecasted amounts, but shall
     not be obliged to meet such requirements if it is not reasonably
     practicable to do so provided that ENDOREX JV shall supply the units of
     PRODUCT so ordered but not immediately available as soon thereafter as
     reasonably practicable.

9.6  The PROJECT TEAM shall agree upon a minimum batch for each form of the
     PRODUCT which shall be manufactured by ENDOREX JV for SCHEIN pursuant to
     the terms of this Agreement.

     ENDOREX JV shall have the right to refuse to fulfil orders which do not
     conform with the provisions of this Clause 9.6.  Where ENDOREX JV in its
     absolute discretion, fulfils any order which does not conform with the
     provisions of this Clause 9.6, the fulfilment of such order by ENDOREX JV
     shall not affect ENDOREX JV's right to refuse to fulfil any subsequent
     order which does not conform with the provisions hereof.

9.7  In advance of the REGULATORY APPROVAL in the USA, the Parties shall discuss
     and agree upon the manufacture and purchase of specific quantities of
     LAUNCH STOCKS; however, for the avoidance of doubt, the parties hereby
     confirm that ENDOREX JV's manufacturing obligations shall only arise on
     receipt of firm purchase orders.  For the avoidance of doubt, ENDOREX JV
     shall only accept orders for LAUNCH STOCKS in respect of the launch of the
     PRODUCT in the USA.

9.8  SCHEIN will notify ENDOREX JV within [*****] of its receipt of an approval
     letter, or a pre-approval letter in respect of a REGULATORY APPLICATION
     from an RHA. SCHEIN shall within [*****] of such notification place a firm
     purchase order with ENDOREX JV for LAUNCH STOCKS, unless such a purchase
     order has already been submitted to ENDOREX JV prior to that date. In
     addition, SCHEIN will use its reasonable efforts to provide forecasts for
     deliveries in addition to the LAUNCH STOCKS for the balance of the year in
     which the REGULATORY APPROVAL is obtained.

9.9  Save as otherwise agreed between the Parties, delivery of consignments of
     PRODUCT shall be effected to SCHEIN or SCHEIN's designee by ENDOREX JV's
     designee EX-WORKS the applicable facility.  Risk of loss of or damage to
     any consignment of the PRODUCT shall pass to SCHEIN or it's designee when
     each such consignment of the PRODUCT is loaded onto the vehicle of SCHEIN
     or SCHEIN's designee's agent on which it is to be despatched from the
     applicable facility.  SCHEIN or it's designee shall fully insure or procure
     the insurance of all consignments of the PRODUCT from the time when risk
     passes as aforesaid and shall produce the supporting insurance when
     requested by ENDOREX JV.

9.10  All claims for failure of any delivery of the PRODUCT to conform in all
      material respects to PRODUCT SPECIFICATIONS under Clause 9 shall be made
      by SCHEIN to ENDOREX JV in writing as soon as possible but in any event
      within 30 days following delivery except in the case of latent defects.
      Claims for latent defects, which could not have been reasonably discovered
      during the routine testing protocol (to be agreed by SCHEIN and ENDOREX
      JV), shall be made by SCHEIN to ENDOREX JV in writing as soon as possible

10.9.  All claims for failure of any shipment of the COMPOUND to conform to the
       COMPOUND SPECIFICATIONS must be made by ENDOREX JV to SCHEIN in writing
       within 30 days following delivery except in the case of latent defects.
       Claims for latent defects shall be made by ENDOREX JV to SCHEIN in
       writing as soon as possible but in any event within 30 days of discovery.
       Failure to make timely claims in the manner prescribed shall constitute
       acceptance of the shipment. COMPOUND which has been delivered and which
       has been shown within the designated period not to conform to COMPOUND
       SPECIFICATIONS shall be replaced at SCHEIN's cost within 90 days of the

       destruction, of such non-conforming bulk COMPOUND. In addition, SCHEIN
       shall be responsible for all costs borne by ENDOREX JV in the use of such
       non-conforming bulk COMPOUND, unless such non-compliance with the

       conforming bulk COMPOUND.

10.11. In the event of an unresolved dispute as to conformity of the COMPOUND
       with the COMPOUND SPECIFICATIONS, the Parties shall within 30 days
       appoint an independent first class laboratory to undertake the relevant

       be entitled, at its sole discretion, to take over some or all of the
       activities associated with the manufacture of the drug vial containing
       the COMPOUND which will be supplied by SCHEIN to ENDOREX JV; provided,
       however, that there may be a transition period of up to 60 days during
       which SCHEIN continues to perform the subject activities but only because
       of commitments to third party suppliers that SCHEIN had agreed to prior
       to the exercise of such right to take over by ENDOREX JV. Any such
       manufacture of the drug vial by ENDOREX JV or ENDOREX JV's designee shall
       be in a competitive manner.

10.15  In the event that any royalty, licence fees or other compensation
       obligations related to the COMPOUND and/or the bulk substance which is
       used to formulate the COMPOUND ("Bulk Substance") are payable to any
       third parties as a result of the use of the COMPOUND in the PRODUCT,
       SCHEIN shall be solely responsible for the payment of any such royalty,
       licence fee or other compensation obligations. For the avoidance of
       doubt, any such royalty, licence fee or other compensation obligations
       relating to the COMPOUND and/or the Bulk Substance shall not be included
       in the calculation of the MANUFACTURING COST of the COMPOUND and shall
       not be deducted from the PROFIT.

       continuous and uninterrupted supply of the Bulk Substance for the
       COMPOUND throughout the TERM of this Agreement. ENDOREX JV shall be
       entitled, at its sole discretion, to forthwith terminate this Agreement,
       in the event that SCHEIN:

       10.16.1  at any time during the TERM of this Agreement, (i) fails to

               PRODUCT in any country of the TERRITORY for which SCHEIN's
               license to the ENDOREX JV BACKGROUND TECHNOLOGY and ENDOREX JV
               IMPROVEMENTS has been terminated in accordance with the terms of

of becoming employed by the Company in this capacity.

     The Company and the Executive desire to set forth in this Agreement the
terms and conditions on which the Executive will be employed by the Company as

     Accordingly, in consideration of the promises and the respective covenants

     will commence on February 21, 2000 and end on February 20, 2004 unless
     further extended or sooner terminated as hereinafter provided.

3.  Position and Duties
     The Executive shall serve as VICE PRESIDENT, FINANCE AND CORPORATE
     DEVELOPMENT of Endorex Corporation and its subsidiaries and shall have such
     responsibilities and authority consistent with this position as may, from
     time to time, be assigned to the Executive by the President/CEO or Board of
     Directors of the Company. The Executive shall devote substantially all his
     working time and efforts to the business affairs of the Company. The
     Executive will report directly to the President/CEO of the Company.

4.  Place of Performance
     In connection with the Executive's employment by the Company, the Executive
     shall be based at the Company's offices in Lake Forest, IL except for
     required travel on the Company's business.

5.  Compensation and Related Matters
     (A)  Salary. During the period of the Executive's employment hereunder, the
          Company shall pay to the Executive a salary at a rate of not less than
          $130,000 per annum, payable in accordance with the Company's normal
          payroll and withholding practices. The Executive's salary and
          performance shall be subject to a review commencing at the end of the
          calendar year but in any case no later than twelve (12) months
          following the commencement of the term of the Executive's employment
          hereunder.

     (B)  Bonuses. At the end of each full year of employment, Executive shall
          be entitled to a targeted bonus of up to 30% of the Executive's annual
          base salary, as in effect at the time. Determination of any actual
          bonus shall be based upon the Executive's meeting mutually agreed

          period of time, and is at the discretion of the President/CEO and the
<PAGE>

          Board of Directors. The written objectives for the first year of this
          Agreement will be established during the first 45 days of employment.
     (C)  Expenses. The Company shall reimburse Executive for all normal, usual
          and necessary expenses incurred by Executive in furtherance of the
          business and affairs of the Company.
     (D)  Other Benefits. The Executive shall be entitled to participate in or
          receive benefits under any employee benefit plan or arrangement made
          available by the Company as of this date and in the future to its key
          management employees, subject to and on a basis consistent with the
          terms, conditions and overall administration of such plans and
          arrangements. Nothing paid to the employee under any plan or
          arrangement presently in effect or made available in the future shall
          be deemed to be in lieu of the salary payable to the employee pursuant
          to paragraph (A) of this section.
     (E)  Vacations. The Executive shall be entitled to three (3) weeks of paid
          vacation in each year of his employment (this will be prorated during
          a calendar year by the amount of time an employee has worked with the
          Company for that given year). The Executive shall also be entitled to
          all paid holidays given by the Company to its employees.
     (F)  Services Furnished. The Company shall furnish the Executive with
          office and such other facilities and services as shall be suitable to
          the Executive's position and adequate for the performance of his
          duties as set forth in Section 3 hereof and for the accomplishment of
          Executive's mutually agreed written objectives.
     (G)  Options and Grants. Subject to execution of this Agreement, Executive
          shall be granted on the date of execution of this Agreement, 60,000
          share options of Endorex's Common Stock at a price per share equal to
          the Closing Price of the Common Stock on the date of execution of this
          Agreement. Such stock and options shall vest and become exercisable at
          the rate of five equal tranches of 12,000 share options beginning with
          the 90-day anniversary of the grant and with each successive tranche
          of 12,000 share options vesting on the annual anniversary of the
          grant. If Executive's employment with the Company shall terminate
          before such stock is fully vested, except as otherwise provided in the
          Company's Amended and Restated 1995 Omnibus Incentive Plan such stock
          shall be exercisable only to the extent the stock is vested on the
          date Executive's employment terminates. The grant of the foregoing
          stock shall not preclude the participation of the Executive in any
          other stock grant or option plan of the Company.

6.  Offices
     The Executive agrees to serve without additional compensation, if elected
     or appointed thereto, as an executive of Endorex or other Endorex
     subsidiaries (collectively "Endorex"), presently existing and as may be
     established in the future, and consistent with the position of the
     Executive with the Company at the time of such appointment, provided that
     the Executive is indemnified for serving in any and all such capacities on
     a basis no less favorable than is currently provided by Article VII of the
     Company's by-laws and any Directors and Officers insurance in effect during
     the term hereof. Executive agrees that, upon termination of his employment
     with the Company, for any reason whatsoever, he will terminate from all
     positions as an employee of Endorex and all of its subsidiaries.

7.  Confidential Information
     Executive covenants and agrees that he will not (except as required in the
     course of his employment or as required by law), while in the employment of
     the Company or thereafter, communicate or divulge to, or use for his own
     benefit, or for the benefit of any other person, firm, association or
     corporation, without the consent of the Company, as applicable, any
     information concerning any inventions, discoveries, improvements,
     processes, formulas, apparatus, equipment, methods, trade secrets,

     course of, or as a result of, his employment with the Company . All

     into contact with, shall remain the sole property of the Company, as
     applicable. The obligations of confidentiality shall not apply to such
     information that (a) is at the time of receipt a matter of public knowledge
     or after its receipt becomes public knowledge through no act or omission on
     the part of Executive, (b) the Executive can establish by reasonable proof
     was known to him prior to disclosure by the Company, (c) is received from a
     third party who did not, directly or indirectly, obtain such information as

     THAT ANY INVENTION, IMPROVEMENT, DISCOVERY, PROCESS, FORMULA, METHOD OR
     OTHER INTELLECTUAL PROPERTY ("INVENTIONS"), WHETHER OR NOT PATENTABLE OR
     COPYRIGHTABLE DEVELOPED BY EXECUTIVE, ALONE OR JOINTLY WITH OTHERS, USING
     MATERIAL, RESOURCES OR FACILITIES OF THE COMPANY OR WHICH RELATE TO
     EXECUTIVE'S WORK FOR THE COMPANY OR ARE BASED ON THE COMPANY'S CONFIDENTIAL
     INFORMATION IS THE EXCLUSIVE PROPERTY OF THE COMPANY. EXECUTIVE ASSIGNS ALL

          direct competition with the Company, or any of its subsidiaries in the
          development, research relating to, manufacture, processing, marketing,

          products ("Products") that were researched, developed, licensed,

          of its subsidiaries, during the twelve (12) month period immediately
          preceding the termination of his employment, provided the Company
          continues to engage in such activities with respect to the Products
          during the Restricted Period. The parties agree that the Company
          currently conducts business in the following areas: 1)
          immunomodulators for cancer and infectious disease and vaccine
          adjuvants based on muramyl dipeptide technology, 2) polymerized

          hereunder.
     (B)  During the period of the Executive's employment by the Company and for
          a period of two (2) years thereafter, Executive will not, directly or

          pursuant to the Securities Exchange Act of 1934.

     (A)  Notwithstanding any provision of this Agreement to the contrary,
          Executive's employment shall automatically terminate upon his death,
          and the Company at any time may terminate his employment immediately
          by giving him written notice of such termination (i) for cause, as
          hereinafter defined; (ii) if Executive shall materially violate any of
          the provisions of Section 7 or 8 hereof; or (iii) if Executive shall
          become physically or mentally incapacitated and by reason thereof be
          unable to perform his duties hereunder for a period of ninety (90)
          consecutive days. For the purpose of clause (i) of this Subsection 9A,
          "for cause" shall mean any of the following events: (x) conviction in
          a court of law of any crime or offense involving money or other
          property of the Company, or any of its subsidiaries, or any felony,
          (y) violation of specific written directions of the President/CEO or
          Board of Directors of the Company, provided, however, no discharge
          shall be deemed "for cause" under this clause (y) unless Executive
          shall have first received written notice from the President/CEO of the
          Company advising of the acts or omissions that constitute such
          violation, and such violation continues uncured for a period of (30)
          days after Executive shall have received such notice, or (z)
          intentional, reckless or grossly negligent conduct by Executive
          constituting misconduct. Termination of Executive by the Company in a
          circumstance other than one stipulated in this Subsection 9A shall
          occur with 30 days written notice, provided that the Company may pay
          Executive salary in lieu of any portion of such notice.
     (B)  Executive may terminate his employment with the Company upon thirty
          (30) days written notice. If Executive terminates his Employment with
          the Company pursuant to this Section 9B, Executive shall only be
          entitled to any unpaid compensation accrued through the last day of
          Executive's employment.
     (C)  In the event that (i) the Company terminates the employment of
          Executive for any reason (other than "for cause" as defined or as a
          consequence of Executive's violation of clause (ii) of Subsection 9A
          above,) or (ii) Executive terminates his employment for Good Reason
          within twelve (12) months after a Change in Control, then Executive

          for a period of six (6) months following termination, subject to set
          off for amounts earned from alternative employment. "Good Reason"
          shall mean a material reduction in Executive's level of
          responsibility, a reduction in his level of base salary or targeted
          bonus level, or a proposed relocation without his consent by more than
          50 miles from Lake Forest, IL. "Change in Control" shall have the same
          meaning as in the Company's Amended and Restated 1995 Omnibus
          Incentive Plan.

10.  Successors: Binding Agreement
     (A)  The Company will require any successor (whether direct or indirect, by
          purchase, merger, consolidation or otherwise) to all or substantially
          all of the business and/or assets of the Company, by agreement in form
          and substance satisfactory to the Executive, to expressly assume and
          agree to perform this Agreement in the same manner and to the same

<PAGE>

          agreement, and Executive is terminated, the Company will terminate
          Executive as stipulated in Section 9(C).
     (B)  This Agreement, and all rights of the Executive hereunder, shall inure

Mr. David Franckowiak
4151 Dubois Blvd.
Brookfield, Illinois

Dear David:

This is to confirm our agreement regarding your departure from Endorex. Your
employment as Vice President/Chief Financial Officer, Treasurer and Corporate
Secretary will be terminated effective at the close of business on March 31,
2000. You will continue to be paid your current base salary of $127,000 per year
up to July 12, 2000. The Company will also pay you four days of unused vacation
time.

You will not accrue any bonuses, vacation, personal time or other employee
benefits during the severance period, except as set forth below. Should you find
another position during this period, the Company will still pay you salary up to
July 12, 2000.

At your request, the Company will continue your employment during the severance
period or until you secure a full-time position with another company, whichever
is earlier (the "Final Termination Date"). Additionally, because of your
expressed interest in assisting the Company during this period, the Company will
also provide you with the following benefits in exchange for your successful
completion of the mutually agreed upon tasks/activities (a listing of which is
attached to this letter) up to the Final Termination Date. Such assistance shall
include but not be limited to your spending a minimum of 7 business days at
Endorex's offices in Lake Forest during the period of March 21 to April 21, with
the specific days to be mutually agreed with Frank Reid.

Benefits to be provided by Endorex (subject to the above) include:

1. A Special Performance Bonus of $6000 upon satisfactory completion of the
attached activities list;

2. Continued participation in the Company's medical insurance, life and
disability insurance, and 401k programs up to the Final Termination Date;

3. An office, telephone, computer and access to the Company fax machine for
business use at the Company's headquarters in Lake Forest up to the Final
Termination Date;

4. Continued vesting of your Oct. 21, 1997 Stock Option Grant to the next
quarterly vesting period (April 21, 2000);

                                       1
<PAGE>

According to our calculations, the number of vested share options you will have
available for exercising at April 21, 2000 is as follows:

  - 10/21/97 Grant = 34,375 shares options @ $2.46875/share exercise price
  -  2/10/98 Grant = 25,000 shares options @ $6.75/share exercise price
  -  2/23/99 Grant =  4,250 shares options @ $2.00/share exercise price
  -------------------------------------------------------------------------
    TOTAL          = 63,625 share options

Please note that according to our stock option plan, you will have a period of
90 days after your Final Termination Date to exercise those stock options that
are vested. You can exercise any of the vested portion of these stock options
during this period, however, you agree not to sell any shares of Endorex stock
acquired through these options prior to your Final Termination Date and while
you are still an employee of the company.

You agree that we were not obligated to provide to you the payments and other
consideration described in this letter (other than 4 months' severance pay). You
accept the severance provisions set forth in this document, notwithstanding the
provisions of paragraph 9 (C) of your employment agreement dated March 10, 1997.
You further agree that your employment with the Company will irrevocably
terminate at the end of the severance period and that the Company will have no
obligations to you at the end of the severance period other than those
specifically described in this letter. In addition, by signing this letter, you
waive any and all claims, demands and causes of action, whether known or
unknown, that you have or may have against Endorex, its shareholders, directors,
officers, employees and agents, arising out of your association with Endorex or
the termination of your employment, existing from the beginning of time to the
date of this letter agreement. Such claims, demands and causes of action
include, but are not limited to, claims for wrongful termination, employment
discrimination or harassment, wage claims, claims involving stock options or
securities laws, tort claims, fraud claims, contract claims, equitable claims or
any other claims relating to your employment with Endorex.

Please confirm your agreement to these terms by signing below.

Sincerely,


/s/ Michael S. Rosen
