PART I

ITEM 1. BUSINESS

GENERAL

NeoTherapeutics, Inc. is a development stage biopharmaceutical company
engaged in the discovery and development of novel therapeutic drugs intended to
treat neurodegenerative diseases and conditions, such as memory deficits
associated with Alzheimer's disease and aging, stroke, spinal cord injuries,
Parkinson's disease, migraine, depression and obesity. The Company's initial
product candidate, NEOTROFIN(TM) (AIT-082, leteprinim potassium) and other
compounds under development are based on the Company's patented technology. This
technology uses small synthetic molecules to create non-toxic compounds,
intended to be administered orally or by injection, that are capable of passing
through the blood-brain barrier to rapidly act upon specific target cells in
specific locations in the central nervous system, including the brain. Animal
and laboratory tests have shown that the Company's AIT-082 compound appears to
selectively increase the production of certain neurotrophic factors, a type of
large protein, in the areas of the brain implicated in memory and in the spinal
cord. These neurotrophic factors regulate nerve cell growth and function. The
Company's technology has been developed to capitalize on the beneficial effects
of these proteins, which have been widely acknowledged to be closely involved in
the early formation and differentiation of the central nervous system. The
Company believes that AIT-082 could have therapeutic and regenerative effects.

The Company's developmental activities to date have benefited from a
close association with the National Institutes of Health ("NIH"). The NIH's
National Institute on Aging ("NIA") has contracted for and funded a portion of
the pre-clinical studies on the Company's AIT-082 compound, including toxicity
studies. The NIA has committed to fund and conduct two Phase 1 clinical trials
under the auspices of its Alzheimer's Disease Cooperative Study ("ADCS"), a
consortium of approximately 35 highly regarded clinical centers throughout the
United States. The NIH's National Institute for Mental Health ("NIMH") also
supported the Company's development efforts by contracting for and providing
funds, along with the NIA, for the production of sufficient quantities of the
AIT-082 compound to conduct some pre-clinical toxicity testing and the two Phase
1 human clinical trials conducted by the ADCS.

In June 1997, an Investigational New Drug Application ("IND") for
AIT-082 was approved by the U.S. Food and Drug Administration ("FDA") and Phase
I human clinical testing in the United States for the treatment of Alzheimer's
disease began. In addition, AIT-082 received a physician's IND in Canada in
March 1997, where a Phase 1 clinical trial for the treatment of Alzheimer's
disease was completed. The Company believes that AIT-082 is the first orally
active drug to enter human clinical trials that is specifically designed to
address the issue of nerve regeneration. In pre-clinical trials, AIT-082 has
been shown to induce the production of multiple neurotrophic factors in the
brain. These factors have been reported to induce the multiplication and
functional maturation, in the brain, of cholinergic neurons, those neurons known
to die in patients with Alzheimer's disease. The Company believes that AIT-082
is the only compound in human clinical trials that has activated, in animals,
multiple genes to produce multiple neurotrophic factors in the specific areas of
the brain associated with memory loss or other deficits.

The Company was incorporated in Colorado in December 1987. On August 7,
1996, the Company changed its name from Americus Funding Corporation to
NeoTherapeutics, Inc. In June 1997, the stockholders approved the
reincorporation of NeoTherapeutics, Inc. as a Delaware corporation. A wholly
owned subsidiary, Advanced ImmunoTherapeutics, Inc. ("AIT"), was incorporated as
a California corporation in June 1987. In July 1989, in a transaction

accounted for as a reverse acquisition, all of the shareholders of AIT exchanged
all of their shares of AIT common stock for shares of the Company's common
stock, and AIT became a wholly owned subsidiary of the Company. In April 1997,
the Company established NeoTherapeutics GmbH ("NEOT GmbH"), a wholly owned
subsidiary in Switzerland, for the purpose of conducting future licensing and
other related activities in the international market. Unless the context
otherwise requires, all references to the "Company" and "NeoTherapeutics" refer
to NeoTherapeutics, Inc., a Delaware corporation, AIT and NEOT GmbH as a
consolidated entity.

INTRODUCTION TO THE CENTRAL NERVOUS SYSTEM

The human brain contains some 10 billion nerve cells, or neurons, each
of which has connections with many other neurons. Sensory, motor and cognitive
activities are all governed by this complex network of neurons, each member of
which communicates with other neurons across junctions known as "synapses."
Communication between neurons involves chemical "messengers" known as
neurotransmitters, which are released by the sending neuron, diffuse across a
small gap, and bind to corresponding receptors on the receiving neuron. Abnormal
neuronal communication has been implicated in a range of psychiatric and
neurological disorders, including memory deficits, schizophrenia, depression,
anxiety, Parkinson's disease and eating disorders.

The treatment of most diseases is facilitated by cell regeneration, a
natural component of human healing. However, in the highly complex realm of
neurological diseases, treatment is more difficult because neurons do not
naturally regenerate efficiently after maturity. Currently available drugs for
the treatment of such significant neurological disorders as Alzheimer's and
Parkinson's diseases act by increasing or replacing supplies of critical
neurotransmitters, but provide time-limited benefits at best. These benefits are
limited because the eventual loss of neuronal cells without regeneration means
there are eventually few nerve cells for those neurotransmitters to activate.

Much of the early neuroscience-oriented biotechnology research centered
on the investigation of certain proteins, known as neurotrophic factors, which
are necessary to the early development of neurons as well as their long-term
maintenance and survival. These substances are involved in the fundamental
formation and shaping of the nervous system. Given their role in the early
neuron development and maintenance, it has been hypothesized that these
neurotrophic factors could be used in the treatment of neurodegenerative
diseases.

Since neurons do not naturally regenerate completely following damage or
disease, substantial research has been conducted by academic researchers and by
the pharmaceutical industry in developing these factors as possible treatments
for a variety of neurological disorders. To date, the usefulness of these
factors has been limited by their inability to pass the blood-brain barrier,
which serves as a "filter" to keep molecules larger than a certain size from
leaving the bloodstream and entering the brain and spinal cord. Therefore,
neurotrophic factors, which are large protein molecules, cannot be administered
orally or through injection into the bloodstream.

There are currently three alternative approaches to achieving
blood-brain barrier access. One approach is to introduce neurotrophic factors by
direct injection into the brain through a catheter inserted into a hole drilled
into the skull. While this treatment has achieved some success in alleviating
some of the symptoms of Alzheimer's disease, the prospect for infection and the
inconvenience and expense of the procedure have limited its practical usefulness
to date. The second approach is to temporarily break down the blood-brain
barrier, which would allow molecules of all sizes (including therapeutic as well
as toxic or infectious agents) to enter into the central nervous system. This
approach is in the early stage of development, and its utility has not been
established.

The third approach, the one taken by the Company, is to find small
molecules which can pass through the blood-brain barrier and which can be
administered orally or through injection into the bloodstream. The
small-molecule approach taken by the Company, if successful, could lead to the
development of compounds which can either mimic the actions of the larger
molecule neurotrophic factors or stimulate the production of such factors within
the brain, after administration either orally or through injection. The Company
believes that such a development could represent a major advance in the
treatment of neurological disorders.

THE COMPANY'S DRUG DEVELOPMENT STRATEGY

The Company is engaged in research that has primarily focused on the
development of new drugs that act on the nervous system to treat
neurodegenerative diseases and conditions, such as memory deficits associated
with Alzheimer's disease and aging, stroke, spinal cord injuries and Parkinson's
disease, migraine, depression and obesity.

The technical strategy employed by the Company is the synthesis of
proprietary chemical molecules that modify specific biological processes in the
body. The methods by which the molecules are synthesized are proprietary and
specific molecules and their methods of use have been patented by the Company.
The Company's drug design methods are based upon the use of hypoxanthine, a
natural non-toxic purine compound which is contained in the genetic material of
all living matter. Hypoxanthine is chemically linked to a variety of other
molecules in order to produce the Company's proprietary AIT series of compounds.
The various molecules that are linked to hypoxanthine are selected from known
drugs that have established therapeutic activity, producing a potentially
bi-functional compound. These compounds exhibit certain functional features of
both hypoxanthine (including its ability to possibly facilitate passage through
the blood-brain barrier) and the linked therapeutic drugs. Chemical and
behavioral studies have given the Company reason to believe that this compound
synthesis and selection process increases the probability that the new AIT
compounds will retain the actions exhibited by their "parent" drugs.

The Company conducts the synthesis and early testing to establish
therapeutic potential necessary to obtain patents on new compounds. In that
regard, the Company has conducted pre-clinical testing of the safety and
efficacy of certain of its compounds and intends to file an IND for each such
compound which shows therapeutic potential. With respect to the Company's
AIT-082 compound, some Phase I clinical trials will be conducted by the ADCS
with the support of the NIH, and the Company intends to conduct all other
clinical trials pending. The Company intends to seek out large pharmaceutical
companies as partners for the development, manufacture and marketing of certain
of its other compounds.

No assurance can be made that any of the Company's compounds will prove
to be effective treatments for the indicated diseases or conditions or for any
other purposes, or that any such compounds will receive FDA approval.

NEOTROFIN(TM) (AIT-082)

The Company's AIT-082 compound is the most extensively studied compound
in the AIT series and has been the primary focus of the Company's research
efforts. AIT-082 has been shown in animal studies to enhance working (or recent)
memory, the type of memory which is deficient in patients suffering from
Alzheimer's disease. In addition, the Company believes that AIT-082 has
potential as a treatment for memory impairments that are seen in the aged and
stroke patients. AIT-082 also has potential for treatment of patients with nerve
damage such as stroke and spinal cord injury.

Pre-clinical testing involving laboratory animals conducted by the
Company and independent research institutions has indicated that AIT-082
exhibits the following properties and/or effects:

o MEMORY: Shown to reduce, delay and prevent memory deficits in aged
animals; shown to enhance memory function in young and aged animals.

o TOXICITY: Shown to be non-toxic at the highest testable oral dosage in
dogs (1,000 mg/kg) and rats (3,000 mg/kg) after at least 90 days of
administration.

o DOSAGE: Effective over a wide range of doses in animals, with
effectiveness observed at doses as low as 0.5 mg/kg and up to 60 mg/kg;
a single dose has been observed to have measurable effects for more than
seven days in mice.

o ADMINISTRATION: Active both orally and through injection.

o SIDE EFFECTS: Has no measured effect in mice on neurological parameters
such as learning rate, motivation, performance or locomotor activity.

Until completion of human clinical trials, there can be no assurance
that these properties and/or effects can be replicated in humans.

The Company has shown that when administered to neurons in tissue
culture, AIT-082 can induce the same neurite outgrowth effects as nerve growth
factor ("NGF"). The Company has also shown that AIT-082 causes the production of
messenger RNA for multiple neurotrophic factors in tissue culture. In addition,
the Company has demonstrated that oral administration of AIT-082 increases the
levels of messenger RNA for multiple neurotrophic factors and proteins in the
central nervous systems of rats and mice. Other researchers have shown, in
animals, that administration of multiple neurotrophic factors may be more
effective as a treatment method than the administration of a single factor. The
Company believes that AIT-082's mechanism of action (after it has passed through
the blood-brain barrier) involves activating the genes that lead to the
production of a number of different neurotrophic factors. Neurotrophic factors
themselves are not orally active and do not pass the blood-brain barrier.
Therefore, should oral AIT-082 prove to be an effective treatment for
neurological disorders, it could have two distinct practical advantages over
neurotrophic factors administered alone directly into the brain as a treatment
for such disorders: (i) it can be administered orally; and (ii) it induces the
production of multiple neurotrophic factors in those areas of the brain
associated with memory.

The NIA and the NIMH have contracted for and completed production of
sufficient quantities of AIT-082 to conduct subchronic animal toxicity studies
and early human clinical trials and have provided the funding for these
contracts. An IND was approved for AIT-082 by the U.S. FDA in June 1997.

The ADCS reviewed the Company's pre-clinical test data and approved
conducting such clinical trials with AIT-082 after FDA approval of the Company's
IND. A Phase 1 clinical study of AIT-082 in the United States began in July
1997. This study and one additional study, initiated in October 1998, will be
paid for and conducted in the United States by the ADCS. In September 1997, the
Geriatric Research Group and Memory Clinic, McMaster University, Hamilton,
Ontario, completed two Phase 1 clinical trials on AIT-082. The composite results
from the Phase 1 clinical trials completed to date confirm that AIT-082 is
rapidly absorbed after oral administration and produces no serious side effects
at high doses. In 1998 the Company completed an additional Phase 1 study (repeat
dosing) and initiated the first Phase 2 study of AIT-082 for 28 days of
treatment. In the first quarter of 1999, the Company completed one Phase 2
clinical trial (28 days of dosing) and initiated a larger, Phase 2 clinical
trial (90 days of dosing) in Canada, Australia and the Republic of South Africa.
The Company expects that it will have to fund additional animal and human
studies that may include an additional Phase 2 and possibly two Phase 3 human
clinical studies prior to submitting AIT-082 to the FDA for marketing approval.
There can be no assurance, however, that clinical trials of AIT-082 will be
successful, that the marketing of AIT-082 will be approved by the FDA, or that
AIT-082 can be successfully marketed to its targeted population. See "Drug
Approval Process and Government Regulation."

OTHER COMPOUNDS IN DEVELOPMENT

Due to the historically limited resources available to the Company and
the Company's decision to focus those resources on the development of its
AIT-082 compound, its other compounds are in earlier stages of development.
These compounds include:

AIT-034: AIT-034 is a distinct chemical analog of hypoxanthine and
pyrollidone that has been demonstrated in animal studies to enhance memory and
to reverse memory deficits in severely impaired animals that do not respond to
AIT-082. AIT-034 does not induce the production of NGF, and its mechanism of
action is therefore believed to be different than AIT-082. The Company believes
that AIT-034 could be a complementary product for Alzheimer's disease. The
Company expects initial toxicity studies on AIT-034 to commence in 1999.

AIT-203: AIT-203 is a chemical derivative of hypoxanthine and dopamine.
The Company believes that AIT-203 has the potential of being developed as a
product for the treatment of Parkinson's disease. The Company plans to expand
pre-clinical testing and initiate toxicity studies on AIT-203 in 1999.

AIT-297: AIT-297 is a derivative of hypoxanthine that has shown in
preliminary studies activities which indicate its potential use for migraine and
hypertension. The Company anticipates expanding pre-clinical testing and
initiating toxicity studies on AIT-297 in 1999.

Until extensive further development and testing is completed, which will
take many years, if undertaken at all, the therapeutic and other effects of
these compounds cannot be established.

PRIMARY THERAPEUTIC TARGETS

ALZHEIMER'S DISEASE. Alzheimer's disease is a neurodegenerative brain
disorder that leads to progressive memory loss and dementia. Alzheimer's disease
generally follows a course of deterioration over eight years or more, with the
earliest symptom being impairment of short-term memory. Alzheimer's disease is
now recognized as the most common cause of severe intellectual impairment in
persons over the age of 65 in the United States, with approximately four million
Americans diagnosed as suffering from Alzheimer's disease. The number of
patients with Alzheimer's disease is expected to reach 14 million by 2050.
Alzheimer's disease is the fourth leading cause of death in the United States
with approximately 100,000 deaths per year. The National Alzheimer's Association
has estimated that the overall care costs required for the treatment and care of
the estimated four million United States Alzheimer's disease patients is $100
billion per year.

The Company is testing two compounds, AIT-082 and AIT-034, which have
shown preliminary indications in animals of enhancing or restoring memory, and
have potential to be used to treat Alzheimer's disease patients.

MEMORY IMPAIRMENT ASSOCIATED WITH AGING. Because the populations of
developed countries are increasingly becoming older, the costs and social burden
of medical care and housing of aged persons suffering from mentally
deteriorative diseases are increasing. The availability of a drug to reduce the
memory impairments associated with aging would not only have a significant
economic impact but would also greatly improve the quality of life for the
elderly population. Both AIT-082 and AIT-034 have shown to be effective in
ameliorating memory loss associated with aging in mice.

STROKE. Among older Americans, stroke ranks as the third leading cause
of death. An estimated 500,000 people in the United States suffer strokes each
year. The costs associated with the treatment and care of stroke patients are
estimated to be approximately $25 billion per year. Most therapeutic approaches
to treating strokes are directed towards correcting the circulatory deficit or
to blocking the toxic effects of chemicals released in the brain at the time of
the stroke. The Company is focusing its emphasis in the treatment of strokes on
protecting the cells from injury or degeneration caused by strokes. Since
AIT-082 has the potential to enhance nerve regeneration, the Company believes
that AIT-082 may prove useful in the treatment of stroke.

SPINAL CORD INJURY. There are an estimated 200,000 severely disabled
survivors of spinal cord trauma in the United States with approximately 10,000
new injuries each year. The cost of care and services for these individuals is
estimated to exceed $10 billion per year. Significant research efforts are
currently being focused on the neurotrophic factors that can initiate and
support new cell development, guide new or damaged nerves to appropriate targets
and maintain neuronal function. Animal studies have shown that functional
restorations are possible with appropriate neurotrophic factors. A major
obstacle to the effective use of these neurotrophic factors is the delivery of
the appropriate neurotrophic factors to the site of damage AIT-082 has been


7


8

shown in mice to cause the production of several neurotrophic factors in the
spinal cord after oral administration, demonstrating that it can effectively
penetrate the blood-brain barrier. The Company believes that AIT-082 could
potentially be used to stimulate the regeneration of nerves damaged by spinal
cord injury. The Company has paid $50,000 and has committed an additional
$50,000 for the establishment of a NeoTherapeutics Fellowship as part of the
Reeve-Irvine Research Center for spinal cord injury at the University of
California, Irvine.

BUSINESS STRATEGY

MARKETING AND SALES

The Company does not currently sell any products and therefore has no
marketing, sales, or distribution organization. However, under the terms of any
contemplated licensing agreement for developing and commercializing AIT-082 or
any of its products, the Company may retain an option to co-market the product
in the United States.

The Company believes the support of the NIA and NIMH, along with ADCS,
the clinical arm of the NIA's research on Alzheimer's disease, contributes
significantly to the future marketing and educational efforts directed to
physicians who treat Alzheimer's disease patients. The Company believes that
this exposure to the leaders in the field of neurodegenerative diseases may
reduce the time and marketing costs required to introduce the Company's products
when and if they are approved by the FDA.

PRODUCTION

The Company currently has its compounds manufactured in large scale by
third party vendors and has no plans to establish its own manufacturing
facilities. In connection with any licensing arrangements it may enter into, the
Company intends to retain the rights to control the manufacturing and sale of
its compounds to its licensees. Preliminary estimates indicate that AIT-082 can
be manufactured cost effectively.

STRATEGIC ALLIANCE

The Company believes that its patented technology platform provides a
major commercial opportunity for developing strategic alliances with larger
pharmaceutical companies. It is the intent of the Company to complete a series
of strategic alliances with multi-national or large regional pharmaceutical
companies having substantial financial capacity, marketing capability and
clinical development expertise. Any potential collaborations will enable the
Company to focus on its inherent strength; namely, exploitation of the
technology platform to develop additional novel therapies.

The most common phase in which industry collaborations are completed is
the discovery stage, since a license for early stage discoveries generally cost
a large pharmaceutical company much less than licensing later stage products.
The Company chose to postpone the structuring of a corporate sponsored licensing
agreement for AIT-082, in favor of an early stage, government-assisted
development program. By completing strategic alliances later in the development
cycle, the Company believes this may create an improved value for its
shareholders that may be reflected in the enhanced terms of any licensing
agreement.

RESEARCH OUTSOURCING

The Company currently has several proprietary compounds in various
stages of preclinical development. From time to time, the Company evaluates
these compounds for efficacy in specialized assays or models. In these instances
the Company has chosen to locate academic researchers who are experts in
performing the desired tests and has provided the researchers, through their
respective academic institutions, with grants to perform the designated tests
while the Company maintains proprietary rights to the compounds and these
studies are performed to the highest standards.

CONTEMPLATED LICENSING TERMS FOR AIT-082

In general, the terms of a licensing agreement anticipated by the
Company for its lead compound, AIT-082, will include an up front payment,
milestone payments, and royalties on product sales.

From time to time, the Company is engaged in licensing discussions with
one or more multinational or regional pharmaceutical companies. No assurance can
be made that any such discussions will result in a commercial transaction on
terms acceptable to the Company.

DRUG APPROVAL PROCESS AND OTHER GOVERNMENT REGULATION

The production and marketing of the Company's products and its research
and development activities are subject to regulation for safety, efficacy and
quality by numerous governmental authorities in the United States and other
countries. In the United States, drugs are subject to rigorous regulation. The
Federal Food, Drug and Cosmetics Act, as amended, and the regulations
promulgated thereunder, as well as other federal and state statutes and
regulations, govern, among other things, the testing, manufacture, safety,
efficacy, labeling, storage, record keeping, approval, advertising and promotion
of the Company's proposed products. Product development and approval within this
regulatory framework take a number of years and involve the expenditure of
substantial resources. In addition to obtaining FDA approval for each product,
each drug manufacturing establishment must be registered with, and approved by,
the FDA. Domestic manufacturing establishments are subject to regular
inspections by the FDA and must comply with Good Manufacturing Practices
("GMP"). To supply products for use in the United States, foreign manufacturing
establishments must also comply with GMP and are subject to periodic inspection
by the FDA or by regulatory authorities in certain of such countries under
reciprocal agreements with the FDA. Drug product and drug substance
manufacturing establishments located in California also must be licensed by the
State of California in compliance with local regulatory requirements.

NEW DRUG DEVELOPMENT AND APPROVAL. The United States system of new drug
approval is one of the most rigorous in the world. According to a February 1993
report by the Congressional Office of Technology Assessment, it costs an average
of $359 million and takes an average of 15 years from discovery of a compound to
bring a single new pharmaceutical product to market. Approximately one in 1,000
compounds that enter the pre-clinical testing stage eventually makes it to human
testing and only one-fifth of those are ultimately approved for
commercialization. In recent years, societal and governmental pressures have
created the expectation that drug discovery and development costs can be reduced
without sacrificing safety, efficacy and innovation. The need to significantly
improve or provide alternative strategies for successful pharmaceutical
discovery, research and development remains a major health care industry
challenge.

DRUG DISCOVERY. In the initial stages of drug discovery before a
compound reaches the laboratory, typically thousands of potential compounds are
randomly screened for activity in an assay assumed to be predictive of a
particular disease process. This drug discovery process can take several years.
Once a "screening lead" or starting point for drug development is found,
isolation and structural determination is initiated. Numerous chemical
modifications are made to the screening lead in an attempt to improve the drug
properties of the lead. After a compound emerges from the above process, it is
subjected to further studies on the mechanism of action, further IN VITRO
screening against particular disease targets and finally, IN VIVO animal
screening. If the compound passes these evaluation points, animal toxicology is
performed to begin to analyze the potential toxic effects of the compound, and
if the results indicate acceptable toxicity findings, the compound emerges from
the basic research mode and moves into the pre-clinical phase.

PRE-CLINICAL TESTING. During the pre-clinical testing stage, laboratory
and animal studies are conducted to show biological activity of the compound
against the targeted disease, and the compound is evaluated for safety. These
tests can take up to three years or more to complete.

INVESTIGATIONAL NEW DRUG APPLICATION (IND). After pre-clinical testing,
an IND is submitted to the FDA to begin human testing of the drug. The IND
becomes effective if the FDA does not reject it within 30 days. The IND must
indicate the results of previous experiments, how, where and by whom the new
studies will be conducted, how the chemical compound is manufactured, the method
by which it is believed to work in the human body, and any toxic effects of the
compound found in the animal studies. In addition, the IND clinical protocol
must be reviewed and approved by an Institutional Review Board comprised of
physicians and lay people at a hospital or clinic where the proposed studies


9


10
will be conducted. Progress reports detailing the results of the clinical trials
must be submitted at least annually to the FDA.

PHASE 1 CLINICAL TRIALS. After an IND becomes effective, Phase 1 human
clinical trials can begin. These studies, involving usually between 20 and 80
healthy volunteers, can take up to one year or more to complete. The studies
determine a drug's safety profile, including the safe dosage range. The Phase 1
clinical studies also determine how a drug is absorbed, distributed, metabolized
and excreted by the body, as well as the duration of its action.

PHASE 2 CLINICAL TRIALS. In Phase 2 clinical trials, controlled studies
of approximately 100 to 300 volunteer patients with the targeted disease assess
the drug's effectiveness. These studies are designed primarily to evaluate the
effectiveness of the drug on the volunteer patients as well as to determine if
there are any side effects on these patients. These studies can take up to two
years or more.

PHASE 3 CLINICAL TRIALS. This phase can last up to three years or more
and usually involves 1,000 to 3,000 patients with the targeted disease. During
the Phase 3 clinical trials, physicians monitor the patients to determine
efficacy and to observe and report any adverse reactions that may result from
long-term and more widespread use of the drug.

NEW DRUG APPLICATION (NDA). After completion of all three clinical trial
phases, the data is analyzed and, if the data indicates that the drug is safe
and effective, an NDA is filed with the FDA. The NDA must contain all of the
information on the drug that has been gathered to date, including data from the
clinical trials. NDAs are often over 100,000 pages in length. After passage of
the Prescription Drug User Fee Act, average review times for new medicine
applications dropped from nearly 30 months in 1992 to less than 18 months in
1996.

FAST TRACK REVIEW. In September 1998, the FDA clarified procedures for
accelerating the approval of drugs to be marketed for serious diseases for which
the manufacturer can demonstrate the potential to address unmet medical needs.
Drugs designated as "fast track" must meet both these qualifications. It is
unclear at this time if AIT-082 will fulfill this requirement as there are
currently approved drugs available for the treatment of Alzheimer's disease. It
may be possible that AIT-082 would qualify for fast track classification in a
different disease indication. At this time the Company has not requested fast
track designation for AIT-082.

The FDA has also made provisions for priority review of drugs. A drug
will qualify for priority review if it provides a significant improvement
compared to marketed products in the treatment, diagnosis or prevention of a
disease regardless if the indication is serious or life-threatening. The Company
believes that AIT-082 will qualify for priority review.

APPROVAL. If the FDA approves the NDA, the drug becomes available for
physicians to prescribe. The Company must continue to submit periodic reports to
the FDA, including descriptions of any adverse reactions reported. For certain
drugs which are administered on a long-term basis, the FDA may request
additional clinical studies (Phase 4) after the drug has begun to be marketed to
evaluate long-term effects.

In addition to regulations enforced by the FDA, the Company is also
subject to regulation under the Occupational Safety and Health Act, the
Environmental Protection Act, the Toxic Substances Control Act, the Resource
Conservation and Recovery Act and other present and future federal, state or
local regulations. The Company's research and development activities involves
the controlled use of hazardous materials, chemicals, viruses and various
radioactive compounds. Although the Company believes that its safety procedures
for handling and disposing of such materials comply with the standards
prescribed by state and federal regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated. In
the event of such an accident, the Company could be held liable for any damages
that result, and any such liability could exceed the resources of the Company.

For marketing outside the United States, the Company or its prospective
licensees will be subject to foreign regulatory requirements governing human
clinical trials and marketing approval for drugs and devices. The requirements
governing the conduct of clinical trials, product licensing, pricing and
reimbursement vary widely from country to country.

RESEARCH AND DEVELOPMENT

Since its inception, the Company has devoted substantially all of its
efforts to research and development. Research and development expenditures were
$615,485 in 1996, $4,508,255 in 1997 and $8,542,034 in 1998.

PATENTS AND PROPRIETARY RIGHTS

Patents and other proprietary rights are vital to the Company's
business. The Company's policy is to seek patent protection for its proprietary
compounds and technology, and it intends to protect its technology, inventions
and improvements to inventions that are commercially important to the
development of its business. The Company also intends to rely on trade secrets,
know-how, continuing technology innovations and licensing arrangements to
develop and maintain its competitive position.

On February 25, 1992, Dr. Alvin Glasky was issued a United States patent
(No. 5,091,432) which establishes proprietary rights for a series of compounds
whose chemistry is based upon a purine, hypoxanthine, and for the use of these
compounds in the treatment of neuroimmunologic disorders. This patent expires on
February 25, 2009. These compounds are bi-functional drugs that combine the
ability of hypoxanthine to be absorbed rapidly into the body with the
pharmacological activity of a second molecular component. These second
components were selected to provide a wide variety of potential therapeutic
applications that act on the central nervous system to treat neurodegenerative
diseases or conditions associated with Alzheimer's disease, impairment
associated with aging, Parkinson's disease, stroke, spinal cord injuries,
migraine and depression. On September 5, 1995, Dr. Glasky was issued a second
United States patent (No. 5,447,939) which covers the treatment of neurological
and neurodegenerative diseases through modification of certain biochemical
processes in cells. This patent expires on July 25, 2014. This second patent
incorporates certain technology developed under the auspices of, and belonging
to, McMaster University in Ontario, Canada. On September 1, 1998, Dr. Glasky was
issued a third United States patent (No. 5,801,184) which relates to the control
of neural activity and the treatment of neurological disorders by controllably
inducing the in vivo genetic expression of naturally occurring protein molecules
including neurotrophic factors. This patent expires on September 1, 2015. This
third patent incorporates certain technology developed under the auspices of,
and belonging to, McMaster University in Ontario, Canada.

All three patents have been assigned to the Company by Dr. Glasky. In
connection with these assignments, Dr. Glasky has been granted a royalty of two
percent of all revenues derived by the Company from the use and sale by the
Company of any products which are covered by any of the aforementioned patents
or any subsequent derivative patents, in each case for the life of the patent.
However, Dr. Glasky will not receive any royalties with respect to sales of
products which utilize patent rights licensed to the Company by McMaster
University. In the event the Company terminates Dr. Glasky's employment without
cause, the royalty rate shall be increased to five percent, and in the event Dr.
Glasky dies, his estate or family shall be entitled to continue to receive
royalties at the rate of two percent.

With respect to the second United States patent, the Company and
McMaster University have entered into a license agreement whereby McMaster
University has licensed to the Company all patent rights belonging to McMaster
University contained in such patent. This agreement calls for minimum payments
by the Company of $25,000 per year to McMaster University, with the first
payment due in July of 1997, and for the Company to pay to McMaster University a
royalty of five percent of the net sales of all products sold by the Company
which incorporate the patent rights licensed to the Company by McMaster
University. The third U.S. patent is covered under this agreement.

In addition to a number of foreign patents which have been granted
corresponding to the first and third United States patents, the Company also
currently has five additional United States patent applications and a number of
corresponding foreign patent applications on file. There can be no assurance,
however, that the scope of the coverage claimed in the Company's patent
applications will not be significantly reduced prior to a patent being issued.

The patent positions of pharmaceutical and drug development companies
are generally uncertain and involve complex legal and factual issues. There can
be no assurance that third parties will not assert patent or other intellectual
property infringement claims against the Company with respect to its products or
technology or other matters. There may be third-party patents and other
intellectual property relevant to the Company's products and technology which
are not known to the Company. Patent litigation is becoming more common in


11


12
the biopharmaceutical industry. Litigation may be necessary to defend against or
assert claims of infringement, to enforce patents issued to the Company, to
protect trade secrets owned by the Company or to determine the scope and
validity of proprietary rights of third parties. Although no third party has
asserted that the Company is infringing such third party's patent rights or
other intellectual property, there can be no assurance that litigation asserting
such claims will not be initiated, that the Company would prevail in any such
litigation or that the Company would be able to obtain any necessary licenses on
reasonable terms, if at all. Any such claims against the Company, whether
meritorious or not, as well as claims initiated by the Company against third
parties, can be time consuming and expensive to defend or prosecute and to
resolve. If competitors of the Company prepare and file patent applications in
the United States that claim technology also claimed by the Company, the Company
may have to participate in interference proceedings declared by the Patent and
Trademark Office to determine priority of invention, which could result in
substantial cost to the Company, even if the outcome were to ultimately be
favorable to the Company. The results of such proceedings are highly
unpredictable and, as a result of such proceedings, the Company may have to
obtain licenses in order to continue to conduct clinical trials, manufacture or
market certain of its products. No assurance can be made that the Company will
be able to obtain any such licenses on favorable terms, if at all.

The Company also relies upon unpatented trade secrets and improvements,
unpatented know-how and continuing technological innovation to develop and
maintain its competitive position, which it seeks to protect in part, by
confidentiality agreements with its employees and consultants and with corporate
partners and/or collaborators as such relationships are formed in the future.
The agreements provide that all confidential information developed or made known
to an individual during the course of the employment or consulting relationship
shall be kept confidential and not disclosed to third parties except in
specified circumstances. In the case of employees, the agreements provide that
all inventions conceived by the individual while employed by the Company shall
be the exclusive property of the Company. There can be no assurance that these
agreements will not be breached, that the Company would have adequate remedies
for breach, or that the Company's trade secrets will not otherwise become known
or be independently discovered by competitors.

COMPETITION

The pharmaceutical industry is characterized by rapidly evolving
technology and intense competition. Many companies of all sizes, including a
number of large pharmaceutical companies as well as several specialized
biotechnology companies, are engaged in activities similar to that of the
Company. The Company's competitors include Amgen, Inc., Bayer AG, Eli Lilly and
Co., Novartis, Bristol-Myers Squibb Company, Glaxo Wellcome PLC, Regeneron
Pharmaceuticals, Inc., Vertex Pharmaceuticals, Inc., Guilford Pharmaceuticals,
Inc., Cephalon, Inc., Warner-Lambert Co., Hoechst Marion Roussel Ltd. and
Pfizer, Inc., among others. In addition, colleges, universities, governmental
agencies and other public and private research institutions will continue to
conduct research and are becoming more active in seeking patent protection and
licensing arrangements to collect license fees, milestone payments and royalties
in exchange for license rights to technologies that they have developed, some of
which may be directly competitive with that of the Company. These companies and
institutions also compete with the Company in recruiting highly qualified
scientific personnel. Many of the Company's competitors have substantially
greater financial, research and development, human and other resources than the
Company. Furthermore, large pharmaceutical companies have significantly more
experience than the Company in pre-clinical testing, human clinical trials and
regulatory approval procedures.

Although the Company has begun to conduct clinical trials with respect
to AIT-082, the Company has not conducted clinical trials with respect to any of
its other compounds under development nor has it sought the approval of the FDA
for any product based on such compounds. Furthermore, if the Company is
permitted to commence commercial sales of products based on compounds it
develops, including AIT-082, and decides to manufacture and sell such products
itself, then the Company will also be competing with respect to manufacturing
efficiency and marketing capabilities, which are areas in which the Company has
no prior experience.

Any product for which the Company obtains FDA approval must also compete
for market acceptance and market share. A number of drugs intended for the
treatment of Alzheimer's disease, memory loss associated with aging, stroke and
other neurodegenerative diseases and disorders are on the market or in the later
stages of clinical testing. Two drugs are currently approved for the treatment
of Alzheimer's disease in the United States and both are cholinesterase
inhibitors: Cognex(R) (tacrine), formerly marketed by Warner-Lambert Co. and
CoCensys, Inc. , and Aricept(R) (donepezil), licensed by Pfizer, Inc. from Eisai
Co., Ltd.


12

13

Certain technologies under development by other pharmaceutical companies
could result in treatments for Alzheimer's disease and other diseases and
disorders for which the Company is developing its own treatments. Several other
companies are engaged in research and development of compounds which use
neurotrophic factors in a manner similar to that of the Company's compounds. In
the event that one or more of these programs are successful, the market for the
Company's products could be reduced or eliminated.

The Company expects technological developments in the neuropharmacology
field to continue to occur at a rapid rate and expects competition will remain
intense as advances continue to be made. Although the Company believes, based on
the preliminary pre-clinical test results involving certain of its compounds,
that it will be able to continue to compete in the discovery and early clinical
development of compounds for neurological disorders, there can be no assurance
that the Company will be able to do so, and the Company does not presently have
sufficient resources to compete with major pharmaceutical companies in the areas
of later-stage clinical testing, manufacturing and marketing.

EMPLOYEES

As of December 31, 1998, the Company had thirty-three full-time
employees, of which seven hold Ph.D. degrees, and one part-time employee. There
can be no assurance that the Company will be able to attract and retain
qualified personnel in sufficient numbers to meet its needs. The Company's
employees are not subject to any collective bargaining agreements, and the
Company regards its relations with its employees to be good.

RISK FACTORS

This Annual Report on Form 10-K contains forward-looking statements
within the meaning of Section 27A of the Securities Act of 1993 and Section 21E
of the Securities Exchange Act of 1934. In light of the important factors that
can materially affect results, including those set forth below, the inclusion of
forward-looking information herein should not be regarded as a representation by
the Company or any other person that the objectives or plans for the Company
will be achieved. Assumptions relating to budgeting, research, and other
management decisions are subjective in many respects and thus susceptible to
interpretations and periodic revisions based on actual experience and business
developments, the impact of which may cause the Company to alter its research,
capital expenditure or other budgets, which may in turn affect the Company's
business, financial position, results of operations and cash flows. The reader
is therefore cautioned not to place undue reliance on forward-looking statements
contained herein, which speak as of the date of this Annual Report on Form 10-K.

HISTORICAL OPERATING LOSSES; EXPECTED CONTINUED LOSSES

We are considered to be a development stage company because we have not
generated revenues from sales. Moreover, even if we eventually generate revenues
from sales, we nevertheless expect to incur significant operating losses over
the next several years. From our inception in 1987 through December 31, 1998, we
have incurred cumulative losses of approximately $23.8 million, almost all of
which consisted of research and development and general and administrative
expenses. Our ability to become profitable will depend on (1) our development of
our proposed products, (2) our obtaining regulatory approvals for such products
and (3) our success in bringing these products to market. Many factors have a
bearing on our likelihood of long-term success. These include the expenses,
difficulties and delays frequently encountered in the development and
commercialization of new pharmaceutical products, competitive factors in the
marketplace and the burdensome regulatory environment in which we operate. It is
possible that we may never achieve significant revenues or become profitable.

EARLY STAGE OF PRODUCT DEVELOPMENT; RISK OF FAILURE

Our proposed products are in an early stage of development. They will
require additional research and development, clinical testing and regulatory
clearances. We do not currently sell any products and do not expect to have any
products commercially available for at least several years. Our proposed
products are subject to the risks of failure inherent in the development of
pharmaceutical products based on innovative technologies. Some of these risks
are that a proposed product (1) could be found to be ineffective or toxic,


13


14

(2) may fail to receive necessary regulatory clearances, (3) will be
uneconomical to manufacture or market, (4) may not be sold because of patent or
other rights of third parties or (5) becomes unmarketable because a third party
introduces a superior or equivalent product. As a result, we are unable to
predict whether our research and development activities will result in any
commercially viable products or applications. Our primary area of therapeutic
focus, disorders of the central nervous system, is not thoroughly understood and
we cannot be certain that our proposed products will prove to be safe or
effective in treating such disorders or any other diseases.

NEED FOR ADDITIONAL FUNDING; UNCERTAIN ACCESS TO CAPITAL

We will require substantial additional capital to further develop our
proposed products and to commercialize any products that may be developed. Our
capital requirements will depend on many factors, including (1) the progress of
our research and development programs, (2) the progress of pre-clinical and
clinical testing, (3) the time and cost involved in obtaining regulatory
approvals, (4) the cost of filing, prosecuting, defending and enforcing patent
claims and other intellectual property rights, (5) competing technological and
market developments and (6) our ability to establish collaborative and other
arrangements with third parties, such as licensing and manufacturing agreements.

On March 27, 1998, we entered into a Private Equity Line of Credit
Agreement with a private investor (the "Equity Line Agreement"). Under the
Equity Line Agreement we may, at our option, sell shares of our common stock to
the investor at a price equal to 88% of the market price of the common stock at
the time of such sales, subject to certain limitations contained in the Equity
Line Agreement. At December 31, 1998, we had the remaining availability of
approximately $11.5 million under the Equity Line Agreement. On January 29,
1999, we entered into an Agreement with two private investors to sell up to $6.0
million of preferred stock with conversion rights into common stock. The initial
tranche of $4.0 million was received on January 29, 1999. At our option, under
certain circumstances, we may sell to the investors an additional $2.0 million
after approximately 6 months.

We believe that our existing capital resources, including the proceeds
from any future sales of our equities under the Equity Line and Preferred Stock
Agreements, will be sufficient to satisfy our current and projected funding
requirements for the next 12 months. Thereafter, we may require substantial
additional capital. Moreover, if we experience unanticipated cash requirements
during the next 12 months, we could require additional capital sooner. We may
seek such additional funding through public or private financing or
collaborative or other arrangements with third parties. We cannot be certain
that additional funds will be available on acceptable terms, if at all. From
time to time, we may receive additional funds from the exercise of our
outstanding warrants and stock options, but we cannot be certain that these will
be exercised or that the amounts we receive will be sufficient for our purposes.
If we raise additional funds by issuing equity securities, our existing
stockholders may experience substantial dilution. We may be able to obtain
additional funds through sales of our common stock under our Equity Line
Agreement, but we may not be able to do so under certain circumstances. If
adequate funds are not available, we may be required to delay, scale back or
eliminate one or more of our development programs. Alternatively, we may obtain
funds by entering into arrangements with third parties. These arrangements may
require us to relinquish rights to certain of our products or technologies that
we would not otherwise relinquish.

DEPENDENCE ON THIRD PARTIES FOR CLINICAL TESTING, MANUFACTURING AND MARKETING

Except with respect to our NEOTROFIN(TM) (AIT-082) compound, we may not
conduct later-stage human clinical trials ourselves or to manufacture any of our
proposed products for commercial sale nor do we have the resources necessary to
do so. We intend to seek larger pharmaceutical companies as partners to conduct
such activities. In connection with our efforts to secure corporate partners, we
will seek to retain certain co-marketing rights to certain of our proposed
products, so that we may promote such products to selected medical specialists
while our corporate partner promotes these products to the medical market
generally. We cannot be certain that we will be able to enter into any such
partnering arrangements on this or any other basis. In addition, we cannot be
certain that we or our potential corporate partners can successfully introduce
our proposed products or that such proposed products will achieve acceptance by
patients, health care providers and insurance companies. Further, it is possible
that we may not be able to manufacture and market our proposed products at
prices that would permit us to make a profit.


14


15

LACK OF OPERATING EXPERIENCE

To date, we have engaged exclusively in the development of
pharmaceutical technology and products. Our management has substantial
experience in pharmaceutical company operations, but NeoTherapeutics itself has
no experience in manufacturing or procuring products in commercial quantities or
in marketing pharmaceutical products and has only limited experience in
negotiating, setting up and maintaining strategic relationships, conducting
clinical trials and other later-stage phases of the regulatory approval process.
We cannot be certain that we will be able to successfully engage in any of these
activities with respect to any of our proposed products which we may attempt to
commercialize. If we decide to establish a commercial-scale manufacturing
facility for NEOTROFIN(TM) (AIT-082), we will require substantial additional
funds and personnel and will be required to comply with extensive regulations
applicable to such a facility. We cannot be certain that we will be able to
successfully develop manufacturing or marketing capabilities either on our own
or through third parties.

NEED TO COMPLY WITH GOVERNMENTAL REGULATION AND TO OBTAIN PRODUCT APPROVALS

Various regulatory agencies in the United States and abroad regulate the
testing, manufacturing, labeling, distribution, marketing and advertising of our
proposed products and our ongoing research and development activities. The U.S.
FDA and comparable agencies in foreign countries impose many requirements on the
introduction of new pharmaceutical products through lengthy and detailed
clinical testing procedures, sampling activities and other costly and time
consuming compliance procedures. Our proprietary compounds will require
substantial clinical trials and FDA review as new drugs. We cannot predict with
certainty when we might submit any of our proposed products currently under
development for regulatory review. Once we submit a proposed product for review,
there can be no assurance that FDA or other regulatory approvals for any of our
proposed products will be granted on a timely basis, if at all. If we are
delayed or fail to obtain such approvals, our business and results of operations
would be damaged. If we fail to comply with regulatory requirements we could be
subject to regulatory or judicial enforcement actions. These actions could
result in product recalls or seizures, injunctions, civil penalties, criminal
prosecution, refusals to approve new products and withdrawal of existing
approvals, as well as potentially enhanced product liability exposure. If we
sell our products outside the United States, we will be subject to regulatory
requirements governing such sales. These requirements vary widely from country
to country and could delay introduction of our proposed products in those
countries.

DEPENDENCE ON KEY PERSONNEL

Our success will depend largely upon the contributions of our key
management and scientific personnel. If we lose the services of any such
personnel we could be delayed in or precluded from achieving our business
objectives. Although we currently have key-man life insurance on Dr. Alvin
Glasky in the face amount of $2 million, the loss of Dr. Glasky's services could
substantially damage our business. We will need substantial additional expertise
in such areas as research, finance and marketing, among others in order to
achieve our business objective. Competition for qualified personnel among
pharmaceutical companies is intense, and the loss of key personnel, or the
inability to attract and retain the additional skilled personnel required for
the expansion of our business, could damage our business.

UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS

We actively pursue a policy of seeking patent protection for our
proprietary products and technologies. We hold three United States patents and
currently have five United States patent applications pending. In addition, we
have numerous foreign patents corresponding to our first patent and have
corresponding patent applications with respect to our second United States
patent and pending United States patent applications which have been filed in
various foreign jurisdictions. We cannot be certain that our patents will
protect us against our competitors. We could be required to file suit to protect
our patents, and we cannot be certain that we will have the resources necessary
to pursue such litigation or otherwise to protect our patent rights.

We also rely on trade secret protection for our unpatented proprietary
technology. However, trade secrets are difficult to protect. It is possible that
others will independently develop substantially equivalent proprietary
information and techniques or otherwise gain access to our trade secrets or that
such trade secrets will be disclosed. We have a policy requiring that our


15


16

employees and consultants execute proprietary information agreements upon
commencement of employment or consulting relationships. These agreements provide
that all confidential information developed or made known to the individual
during the course of the relationship shall be kept confidential except in
specified circumstances. However, these agreements may not successfully protect
our trade secrets or other proprietary information.

We cannot be certain that others will not assert claims against us based
on patents held by others. Such claims, if brought, could seek damages as well
as an injunction prohibiting clinical testing, manufacturing and marketing of
the product at issue. Such claims may or may not be successful. If any such
actions are successful, in addition to any potential liability for damages, we
could be required to obtain a license in order to continue to manufacture or
market the product at issue. It is possible that any license required under any
such patent would not be made available on acceptable terms, if at all. There
has been, and we believe that there will continue to be, significant litigation
in the pharmaceutical industry regarding patent and other intellectual property
rights. If we become involved in any litigation, a substantial portion of our
financial and personnel resources could be consumed, regardless of the outcome
of such litigation.

COMPETITION

Competition in the pharmaceuticals market is intense. Many companies,
both public and private, including well-known pharmaceutical companies, are
engaged in the development of products for certain of the applications we are
pursuing. Most of these companies have substantially greater financial, research
and development, manufacturing and marketing experience and resources than we do
and represent significant long-term competition. In addition, numerous other
companies are in the process of developing products for the treatment of
diseases and disorders for which we are developing products. Such companies may
develop pharmaceutical products that are more effective or less costly than any
products which we may develop.

Factors affecting competition in the pharmaceutical industry vary
depending on the extent to which the competitor is able to achieve a competitive
advantage based on proprietary technology. If we are able to establish and
maintain a significant proprietary position with respect to our proposed
products, competition will likely depend primarily on the effectiveness of the
particular product and the number, gravity and severity of its unwanted side
effects as compared to alternative products or treatments.

We compete in an industry which is characterized by extensive research
and development efforts and rapid technological progress. Although we believe
that our proprietary position may give us a competitive advantage with respect
to our proposed products, new developments are expected to continue and it is
possible that discoveries by others will render our potential products
noncompetitive. Our competitive position also depends on our ability to attract
and retain qualified scientific and other personnel, develop effective
proprietary products, implement development and marketing plans, obtain patent
protection and secure adequate capital resources. We cannot be certain that we
will be able to do so.

DILUTIVE EFFECT OF CONVERSION OF SERIES A PREFERRED STOCK

As of March 16, 1999, there were outstanding a total of 400 shares of
Series A Preferred Stock. These shares presently are convertible, at any time at
the option of their holders, into an aggregate of 306,278 shares of our common
stock. After April 27, 1999, the conversion price of the Series A Preferred
Stock may decrease. After such date the conversion price of the Series A
Preferred Stock will be equal to the lesser of $13.06 per share of common stock
or 101% of the average of the ten lowest closing bid prices of the common stock
occurring in the 30 trading days preceding the particular conversion. However,
in no event can all 400 outstanding shares of Series A Preferred Stock convert
into more than 1,450,000 shares of our common stock. In the event the conversion
prices decreases, the number of shares of our common stock to be issued upon
conversion will increase proportionately. The conversion of the Series A
Preferred Stock into an increasing number of shares of common stock could cause
the market price of our common stock to drop.


16
17

SHARES ELIGIBLE FOR FUTURE SALE

As of March 16, 1999, security holders held options and warrants which,
if exercised, would obligate us to issue 4,206,332 shares of common stock.
Substantially all of such shares, when issued upon exercise, will be available
for immediate resale in the public market. In addition, at March 16, 1999, our
Equity Line Agreement provides that we may issue common stock in exchange for up
to an additional $10.75 million. The shares of common stock which the Company
may sell under our Equity Line Agreement will be available for immediate resale
in the public market. The market price of our common stock could drop because of
such resales.

DILUTIVE AND OTHER EFFECTS OF FUTURE EQUITY ISSUANCES

If we issue equity securities, such issuances may have a dilutive impact
on our other stockholders. Additionally, such issuances would cause our net
income (loss) per share to decrease (increase) in future periods. As a result,
the market price of our common stock could drop. In addition, if we issue common
stock under our Equity Line Agreement, it will be issued at a discount to its
then-prevailing market price. These discounted sales could cause the market
price of our common stock to drop.

RISK OF PRODUCT LIABILITY

Although we currently carry product liability insurance, it is possible
that the amounts of such coverage will be insufficient to protect us from future
claims. Further, we cannot be certain that we will be able to obtain or maintain
additional insurance on acceptable terms for our clinical and commercial
activities or that such additional insurance would be sufficient to cover any
potential product liability claim or recall. Failure to maintain sufficient
insurance coverage could have a material adverse effect on our business and
results of operations.

USE OF HAZARDOUS MATERIALS

Our research and development efforts involve the use of hazardous
materials. We are subject to federal, state and local laws and regulations
governing the storage, use and disposal of such materials and certain waste
products. We believe that our safety procedures for handling and disposing of
such materials comply with the standards prescribed by federal, state and local
regulations. However, we cannot completely eliminate the risk of accidental
contamination or injury from these materials. If there was an accident, we could
be held liable for any damages that result. Such liability could exceed our
resources. We may incur substantially increased costs to comply with
environmental regulations if we develop our own commercial manufacturing
facility.

VOLATILITY OF STOCK PRICE

The stock market from time to time experiences significant price and
volume fluctuations that are unrelated to the operating performance of
particular companies. These broad market fluctuations may cause the market price
of our common stock to drop. In addition, the market price of our common stock
is highly volatile. Factors that may cause the market price of our common stock
to drop include fluctuations in our results of operations, timing and
announcements of our technological innovations or new products or those or our
competitors, FDA and foreign regulatory actions, developments with respect to
patents and proprietary rights, public concern as to the safety of products
developed by us or others, changes in health care policy in the United States
and in foreign countries, changes in stock market analyst recommendations
regarding our common stock, the pharmaceutical industry generally and general
market conditions. In addition, the market price of our common stock may drop if
our results of operations fail to meet the expectations of stock market analysts
and investors.

CONTROL BY DIRECTORS AND EXECUTIVE OFFICERS

Our directors and executive officers beneficially own in the aggregate
approximately 26.8% of our outstanding common stock. These stockholders, if they
acted together, would be able to exert substantial control over matters
requiring approval by our stockholders. These matters would include the election
of directors and the approval of mergers or other business combination
transactions. This concentration of ownership may discourage or prevent someone
from acquiring our business.


17


18

EFFECT OF CERTAIN CHARTER AND BYLAWS PROVISIONS

Certain provisions of our Certificate of Incorporation and Bylaws may
make it more difficult for someone to acquire control of us. These provisions
may make it more difficult for stockholders to take certain corporate actions
and could delay or prevent someone from acquiring our business. These provisions
could limit the price that certain investors might be willing to pay for shares
of our common stock.

THE YEAR 2000 ISSUE

The Year 2000 issue (the "Year 2000 Issue") in computers arises from the
common industry practice of using two digits to represent a date in computer
software code and databases to enhance both processing time and save storage
space. Therefore, when dates in the year 2000 and beyond are indicated and
computer programs read the date "00," the computer may default to the year
"1900" rather than the correct "2000." This could result in incorrect
calculations, faulty data and computer shutdowns, which would cause disruptions
of operations. In addition, the year 2000 is a leap year and systems need to
recognize it as such.

We have completed an inventory and risk assessment of our internal
information technology ("IT") system applications (including voice and data
systems), our internal non-IT facilities systems (including embedded software in
environmental controls, security systems, fire protection systems, elevators and
public utility connections for gas, electric and telephone systems), and
embedded and external software contained in laboratory and other equipment that
we believe could be adversely affected by the Year 2000 Issue. We believe that
our internal systems are, at the present time, substantially compliant based
upon internal systems tests, currently available information and reasonable
assurance by our equipment and software vendors. Any costs to remediate Year
2000 Issues with regard to these systems are not anticipated to be material.

In June of 1998, we began sending questionnaires to and/or contacting
our outside vendors regarding their state of readiness with respect to
identifying and remediating their Year 2000 Issues. We have completed our risk
assessment of our outside vendors and are currently reviewing their compliance.
We cannot be certain that our vendors will adequately address their Year 2000
Issues. Furthermore, we cannot determine that third parties upon which our
vendors depend will accomplish adequate remediation of their Year 2000 Issues.
Except for our public utility service vendors, who have indicated that they
expect to be in compliance by mid-1999, we believe that, with respect to the
computer systems of our major outside vendors, should a Year 2000 Issue exist
whereby a vendor was unable to address our needs, alternative vendors have been
identified and are readily available that could furnish us with the same or
similar supplies or services that we presently receive from these vendors
without undue cost or expense.

Based on currently available information, we believe that the impact of
the Year 2000 Issue, as it relates to our internal operations, information
systems and software applications will not be material. In the event we fail to
successfully resolve our Year 2000 Issues with respect to our internal systems
in a timely manner, we believe that, while such events would be disruptive to
our operations in the short term, such circumstances would not have a material
adverse effect on our business, financial condition and results of operations
over the long term. However, failure of the major third parties, in particular
the financial institutions with which we have significant banking and investment
management relationships and our third party manufacturers, to be Year 2000
compliant could have a material adverse effect on our business, financial
condition and results of operations or business prospects.


ITEM 2. PROPERTIES

During June 1997, the Company relocated its research and development and
corporate administrative offices to a new 34,000 square foot facility
constructed for it in Irvine, California. The facility is occupied under a
non-cancellable lease for seven years and contains two five year options to
renew. The monthly rent for the Irvine facility is $38,800 plus taxes, insurance
and common area maintenance and, beginning in July 1999, minimum cost of living
increases. The Company also maintains a small administrative office in Zurich,
Switzerland on an expense sharing basis.

ITEM 3. LEGAL PROCEEDINGS

On December 10, 1998, the Company was served with a lawsuit initiated by
four former employees of the Company. The lawsuit, which was filed in the
Superior Court of Orange County, California, also names Dr. Alvin J. Glasky, the
Company's founder and Chief Executive Officer, as a defendant. The lawsuit
arises from a dispute concerning the termination, as of December 31, 1997, of
agreements entered into as of June 1990 and December 1993 between the Company
and each of the former employees, pursuant to which the employees agreed to
accept an aggregate of 278,589 shares of the Company's common stock, subject to
forfeiture provisions, in exchange for the cancellation of indebtedness owed to
them by the Company arising from unpaid compensation and expenses in the total
amount of $458,411. Pursuant to the agreements, the employees were not entitled
to keep the shares unless the Company achieved certain revenue goals by a
specified date, as determined by the Company's independent auditors in
accordance with generally accepted accounting principles. Under the agreements,
as amended, the Company was required to achieve total operating revenues from
the date of each agreement through December 31, 1995, in a cumulative amount of
at least $500,000. When the Company failed to achieve this goal, the agreements
were amended to extend the deadline until December 31, 1997 and increase the
revenue goal to a cumulative amount of at least $1,000,000. The agreements
provide that, if the revenue goals are not achieved by the stated deadline, the
shares will be forfeited and the employees will be required to return the shares
to the Company. The Company did not achieve the required revenue goals either by
December 31 1995, or by December 31, 1997. The Company's total revenues from
inception through December 31, 1995 were only $497,128. The Company did not
have any revenues in 1996 or 1997, and the total revenues from inception through
December 31, 1997 remained at $497,128. In the lawsuit the plaintiffs allege,
among other things, that the cumulative revenues of the Company were or should
have been in excess of $500,000 as of December 31, 1995, and that the defendants
fraudulently induced the plaintiffs into entering into the agreements and the
subsequent amendments to the agreements. The lawsuit asks for damages in excess
of $4,000,000 or, in the alternative, that the forfeiture restrictions be
removed and the plaintiffs be allowed to keep their shares of common stock. The
plaintiffs are also seeking punitive damages and reimbursement of attorneys'
fees and costs. In March 1999, the Company filed a cross-complaint against the
plaintiffs to seek a determination that the plaintiffs' shares have in fact been
forfeited, and to obtain a court order requiring the plaintiffs to return their
shares to the Company for cancellation. The lawsuit is in the early stages of
discovery and no trial date has been set. Management of the Company believes
that the plaintiffs' claims are without merit and that the resolution of this
matter will not have a material adverse effect on the financial condition or
operations of the Company. The Company intends to vigorously defend the lawsuit
and to pursue the cross-complaint for the return and cancellation of all of the
disputed shares. At the same time that the plaintiffs entered into their
agreement with the Company in 1990 and 1993, Dr. Alvin J. Glasky and his wife,
who was then and is now an employee of the Company, also entered into
agreements with the Company that were identical to those entered into by the
plaintiffs, pursuant to which Dr. and Mrs. Glasky received an aggregate of
400,244 shares of common stock subject to identical forfeiture provisions, in
exchange for the cancellation of indebtedness owed to them by the Company
arising from unpaid compensation and expenses in the total amount of $755,531.
Dr. and Mrs. Glasky entered into an agreement with the Company on December 21,
1998, pursuant to which they have agreed to surrender for cancellation the same
proportion of their restricted shares as the plaintiffs are required to
surrender based on the final resolution of the lawsuit. Until such time as the
lawsuit is finally resolved, the Company is accounting for all of these shares,
which it deems to be forfeited, as issued and outstanding.

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

RESULTS OF OPERATIONS

OVERVIEW

From the Company's inception in June 1987 through December 31, 1998, the
Company devoted its resources primarily to fund research and development, and
incurred a cumulative net loss of approximately $23.8 million. During this
period, the Company had only limited revenues from grants, and had no revenues

22

23
from the sale of products or other sources. The Company expects its operating
expenses to increase over the next several years as it expands its research and
development and commercialization activities and operations. The Company expects
to incur significant additional operating losses for at least the next several
years unless such operating losses are offset, if at all, by licensing revenues
under strategic alliances with larger pharmaceutical companies which the Company
currently is seeking. To obtain working capital, the Company entered into an
equity agreement with a private investor in March 1998 which allows the Company
to sell to the investor over a two and one-half year period, at the Company's
sole discretion but subject to certain restrictions, up to $15 million of its
common stock. At March 16, 1999, the Company had $10.75 million remaining on the
Line of Equity. In January 1999, the Company sold $4 million of Preferred Stock
to private investors. See - Liquidity and Capital Resources.

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

The Company had no revenues for the twelve month periods ended December
31, 1998 or 1997.

Research and development expenses for the twelve months ended December
31, 1998, increased by approximately $4.0 million, or 90% over the previous
year. This increase was due primarily to the costs and expenses associated with
the conduct of clinical and preclinical trials as the Company accelerated its
program to commercialize its lead compound, NEOTROFIN(TM) (AIT-082). These costs
and expenses were primarily in the categories of salaries due to additional
personnel, rent, contract manufacturing and formulation of drug compounds,
outside preclinical testing and the increased number and length of clinical
trials.

General and administrative expenses increased approximately $0.8
million, or 33%, for the year ended December 31, 1998, over the year ended
December 31, 1997. General and administrative expenses for 1998 reflect
increased expenses related to additional personnel, insurance, professional and
consulting fees, commissions, facilities rent and travel. The Company expects
general and administrative expenses to continue to increase in future periods
due to expected increases in both research and development and sales and
marketing activities associated with attempting to bring one or more of its
products to market.

Interest income decreased by approximately $0.5 million, or 68%, in 1998
over 1997 due to increased use of cash to fund current operations. The Company
expects its interest earnings to decrease over the next year as it continues to
use its cash to fund current operations.

Year Ended December 31, 1997, Compared to Year Ended December 31, 1996

The Company had no revenues for the twelve month periods ended December
31, 1997 or 1996.

Research and development expenses for the twelve months ended December
31, 1997, increased by approximately $3.9 million, or 632%, over 1996. This
increase was due primarily to the costs and expenses associated with the
commencement of clinical trials as well as personnel additions, salary
increases, facilities rent, consulting fees, license fees and insurance costs as
the Company expanded its operations and used the proceeds from the September
1996 initial public offering of common stock.

General and administrative expenses increased approximately $1.7 million
or 255% for the year ended December 31, 1997, over the year ended December 31,
1996. General and administrative expenses for 1997 reflect increased expenses
related to additional personnel, salary increases, insurance, professional and
consulting fees, commissions, facilities rent, travel, regulatory agency and
other fees associated with being a public company which were all either
significantly higher in 1997 than in 1996 or were initially incurred in 1997. In
1996, the Company operated for a portion of the year on a rent-free basis from
the Chief Executive Officer's residence with very limited administrative and
technical staff.

Interest income increased by approximately $0.5 million or 178% in 1997
over 1996 as a result of the full year's utilization of invested and unallocated
proceeds from the September 1996 initial public offering.

LIQUIDITY AND CAPITAL RESOURCES

From inception through December 1998, the Company financed its
operations primarily through grants, sales of securities, borrowings and
deferred payment of salaries and other expenses from related parties. During
September and October 1996, the Company effected the sale of a total of
2,700,000 units of its common stock and attached warrants to the public. Each
unit consisted of one share of common stock and one warrant to purchase one
share of common stock. The Company realized net cash proceeds of approximately
$18.2 million from the sale.

23

24

On March 27, 1998, the Company executed an agreement with a private
investor (the "Equity Line Agreement") which provides for the Company, at its
sole discretion, subject to certain restrictions, to sell ("put") to the
investor up to $15 million of its common stock. The Equity Line Agreement
expires in August 2001 and, among other things, provides for minimum and maximum
puts ranging from $250,000 to $2.0 million, depending on the Company's stock
price and trading volume. Puts cannot occur more frequently than every 15 days,
and are subject to a discount of 12% from the then current average market price
of the Company's common stock, as determined under the Equity Line Agreement. In
addition, the Company issued to the investor 5-year warrants to purchase 25,000
shares of common stock at $11.62 per share. Through December 31, 1998, the
Company had received proceeds of approximately $3.5 million from sales of common
stock under the Equity Line Agreement. The Company received an additional $0.7
million in January 1999, and as of March 16, 1999, an additional $10.75 million
remains available under the Equity Line Agreement.

To supplement the Equity Line Agreement for the purpose of funding the
Company's planned larger clinical trials, on January 29, 1999, the Company
entered into a financing transaction to sell to two private investors up to $6
million of preferred stock in two tranches. The first tranche of $4.0 million
was sold on January 29, 1999, and for an initial period of 120 days is
convertible into common stock at a fixed price of $13.06 per share. Thereafter,
the preferred stock is convertible at the lesser of the fixed price or at a
variable rate of 101% of the average market price for the ten lowest of the
thirty days immediately preceding the conversion date. In no event can the first
tranche be converted into more than 1,450,000 shares. The second tranche of $2.0
million, which is at the Company's option, can be sold during the period of July
28, 1999 through September 16, 1999, subject to the satisfaction by the Company
of certain conditions. The preferred stock in the second tranche will contain
terms and conditions for conversion similar to the first tranche, except that
the fixed conversion price will be set at 125% of the average market price of
the common stock at the time of the second closing. Dividends on the preferred
stock are payable in cash or in common stock, at the option of the Company, at
the annual rate of 5%. Additional features of the preferred stock issue include,
among other things, a redemption feature at the Company's option if the common
stock trades below a floor of $5 per share or above a ceiling of $20 per share.

At December 31, 1998, the Company had working capital of approximately
$1.0 million which included cash and equivalents of approximately $1.1 million
and short-term investments of approximately $1.8 million. In comparison, at
December 31, 1997, the Company had working capital of approximately $7.0 million
which included cash and cash equivalents of approximately $7.0 million (of which
approximately $0.9 million was restricted) and short-term investments of
approximately $2.1 million. The $6.0 million decrease in working capital is
attributable primarily to the funding of the $11.6 million operating loss for
the year ended December 31, 1998, offset in part by a borrowing collateralized
by equipment ($1.5 million) and equity transactions, principally utilization of
the Equity Line Agreement, of approximately $4.0 million.

Through December 31, 1998, the Company spent (principally in 1997)
approximately $4.0 million for capital equipment and leasehold improvements of
which $1.5 million was borrowed from a finance company pursuant to a $2 million
equipment line of credit agreement. In 1999, the Company intends to spend
approximately $1 million for additional equipment as it further expands its
research and development laboratories, and to partially finance these capital
equipment acquisitions by utilizing the $500,000 remaining under its existing
equipment line of credit agreement. The Company has pledged substantially all of
its tangible assets as collateral for this borrowing. The Company has also
granted to the finance company a warrant to purchase up to 13,459 shares of its
common stock at $7.43 a share.

Effective June 1997 the Company entered into a non-cancelable long-term
operating lease with a major developer. The initial lease term is seven years
with two renewal options for five years each at the then fair market value rate.
Minimum rental commitments under this lease for the five and one-half year
period from January 1999 through June 2002 are approximately $483,100 (1999),
$500,500 (2000 and 2001), $538,100 (2002), $554,200 (2003) and $285,400 (2004).
In addition to rentals, the Company is obligated under the lease for real
property taxes, insurance and maintenance.

In October 1998 the Company entered into an agreement with a contract
research organization to conduct a clinical trial in three countries involving
approximately 400 patients. The agreement, which is cancelable by either party
upon thirty days notice, is expected to result in aggregate expenditures ranging
from $4 to $5 million over the course of one year. Through December 31, 1998,
the Company had expended approximately $360,000 in connection with this


24


25
clinical trial, of which approximately $265,000 was reflected as an advance at
December 31, 1998, for services to be rendered in 1999.

The Company has committed to spend approximately $442,000 in 1999 and
$178,000 in 2000 to a number of universities to conduct general scientific
research programs and to provide for Fellowship Grants.

Since its inception, the Company has been in the development stage and
therefore devotes substantially all of its efforts to research and development.
The Company has incurred cumulative losses of approximately $23.8 million
through December 31, 1998, and expects to incur substantial losses over the next
several years. The Company's future capital requirements and availability of
capital will depend upon many factors, including continued scientific progress
in research and development programs, the scope and results of preclinical
studies and clinical trials, the time and costs involved in obtaining regulatory
approvals, the cost involved in filing, prosecuting and enforcing patent claims,
competing technological developments, the cost of manufacturing scale-up, the
cost of commercialization activities and other factors which may not be within
the Company's control. While the Company believes that its existing capital
resources will be adequate to fund its capital needs for at least 12 months of
operations, the Company also believes that ultimately it will require
substantial additional funds in order to complete the research and development
activities currently contemplated and to commercialize its proposed products. If
the Company is successful in obtaining additional funding, the Company's
existing stockholders could experience substantial dilution to their shares of
stock.

Without additional funding, the Company may be required to delay, reduce
the scope of or eliminate one or more of its research and development projects,
or obtain funds through arrangements with collaborative partners or others which
may require the Company to relinquish rights to certain technologies, product
candidates or products that the Company would otherwise seek to develop or
commercialize on its own, and which could be on terms unfavorable to the
Company.

YEAR 2000 READINESS DISCLOSURE

All statements contained in the following section are "Year 2000 Readiness
Disclosures" within the meaning of the Year 2000 Information and Disclosure Act.

The Year 2000 issue (the "Year 2000 Issue") in computers arises from
the common industry practice of using two digits to represent a date in computer
software code and databases to enhance both processing time and save storage
space. Therefore, when dates in the year 2000 and beyond are indicated and
computer programs read the date "00," the computer may default to the year
"1900" rather than the correct "2000." This could result in incorrect
calculations, faulty data and computer shutdowns, which would cause disruptions
of operations. In addition, the year 2000 is a leap year and systems need to
recognize it as such.

The Company has developed a multi-phase program for Year 2000 Issues
that consists of the following: (i) assessment of the corporate systems and
operations of the Company that could be affected by the Year 2000 Issue, (ii)
remediation of non-compliant systems and components, if any, and (iii) testing
of systems and components following remediation. The Company has focused its
Year 2000 compliance assessment program on four principal areas: (a) the
Company's internal information technology system applications, including voice
and data systems ("IT Systems"), (b) the Company's internal non-IT facilities
systems, including embedded software in environmental controls, security
systems, fire protection systems, elevators and public utility connections for
gas, electric and telephone systems ("Facilities Systems"), (c) embedded and
external software contained in laboratory and other equipment ("Equipment"), and
(d) Year 2000 compliance by third parties with which the Company has a material
relationship, such as significant vendors, financial institutions and insurers.

The Company has completed an inventory and risk assessment of its own
internal IT Systems, Facilities Systems, and Equipment that it believes could be
adversely affected by the Year 2000 Issue, and believes that its own internal
systems are, at the present time, substantially compliant based upon internal
systems tests, currently available information and reasonable assurance by its
equipment and software vendors. The cost to remediate the Year 2000 Issues with
regard to the Company's IT and Facility Systems and Equipment is not material.

In June of 1998, the Company began sending questionnaires to and/or
contacting its outside vendors regarding their state of readiness with respect
to identifying and remediating their Year 2000 Issues. The Company has


25


26
completed its risk assessment of its outside vendors and is currently reviewing
their compliance. It is not possible for the Company to determine or be assured
that adequate remediation of the Year 2000 Issue will be accomplished by such
vendors. Furthermore, it is not possible for the Company to determine or be
assured that third parties upon which the Company's vendors are dependent, will
accomplish adequate remediation of their Year 2000 Issues. Except for the
Company's public utility service vendors, who have indicated that they expect to
be in compliance by mid-1999, the Company believes that, with respect to the
computer systems of its major outside vendors, should a Year 2000 Issue exist
whereby a vendor was unable to address the Company's needs, alternative vendors
have been identified and are readily available that could furnish the Company
with the same or similar supplies or services that it presently receives from
these vendors without undue cost or expense.

Based on currently available information, the Company believes that
the impact of the Year 2000 Issue, as it relates to its IT Systems, Facilities
Systems, Equipment and third parties will not be material. In the event the
Company were to fail to successfully implement its solutions to the Year 2000
Issues with respect to its internal systems in a timely manner, the Company
believes that while such events would be disruptive to the Company's operations
in the short term, such circumstances would not have a material adverse effect
on the business, financial condition and results of operations of the Company
over the long term. However, failure of the major third parties, in particular
the financial institutions with which the Company has significant banking and
investment management relationships and the Company's third party manufacturers,
to be Year 2000 compliant could have a material adverse effect on the Company's
business, financial condition and results of operations or business prospects.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

QUANTITATIVE DISCLOSURES

The Company is exposed to certain market risks associated with interest
rate fluctuations on its marketable securities and borrowing arrangements. All
investments in marketable securities and borrowing arrangements are entered into
for purposes other than trading. The Company is not subject to risks from
currency rate fluctuations. In addition, the Company does not utilize hedging
contracts or similar instruments.

The Company's exposure to interest rate risk arises from financial
instruments entered into in the normal course of business. Certain of the
Company's financial instruments are fixed rate, short-term investments in
government and corporate notes and bonds, which are available for sale (and have
been marked to market in the accompanying financial statements). Changes in
interest rates generally affect the fair value of these investments, however,
because these financial instruments are considered "available for sale," all
such changes are reflected in the financial statements in the period affected.

The Company's borrowings bear interest at fixed annual rates. Changes in
interest rates generally affect the fair value of such debt, but do not have an
impact on earnings or cash flows. Because of the relatively short-term nature of
the Company's borrowings, fluctuations in fair value are not deemed to be
material.

QUALITATIVE DISCLOSURES

The Company's primary exposures relate to (1) interest rate risk on its
borrowings, (2) the Company's ability to pay or refinance its borrowings at
maturity at market rates, (3) interest rate risk on the value of the Company's
investment portfolio and rate of return, (4) the impact of interest rate
movements on the Company's ability to obtain adequate financing to fund future
cash requirements. The Company manages interest rate risk on its investment
portfolio by matching scheduled investment maturities with its cash
requirements. The Company manages interest rate risk on its outstanding
borrowings by using fixed rate debt. While the Company cannot predict or manage
its ability to refinance existing borrowings and investment portfolio,
management evaluates the Company's financial position on an ongoing basis.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



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


We have audited the accompanying consolidated balance sheets of
NeoTherapeutics, Inc. (a Delaware corporation in the development stage) and
subsidiaries as of December 31, 1997 and 1998, and the related consolidated
statements of operations, stockholders' equity (deficit) and cash flows for each
of the three years in the period ended December 31, 1998 and for the period from
inception (June 15, 1987) to December 31, 1998. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of NeoTherapeutics,
Inc. and subsidiaries as of December 31, 1997 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998 and for the period from inception to December 31, 1998, in
conformity with generally accepted accounting principles.

NEOTHERAPEUTICS, INC. AND SUBSIDIARIES
(A DEVELOPMENT STAGE ENTERPRISE)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 1998

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND NATURE OF BUSINESS

NeoTherapeutics, Inc. (the "Company") was incorporated in Colorado as
Americus Funding Corporation ("AFC") in December 1987. In August 1996, AFC
changed its name to NeoTherapeutics, Inc. and in June 1997, the Company was
reincorporated in the state of Delaware. At December 31, 1998, the Company had
two wholly owned subsidiaries, Advanced ImmunoTherapeutics, Inc. ("AIT"),
incorporated in California in June 1987, and NeoTherapeutics GmbH ("NEOT GmbH"),
incorporated in Switzerland in April 1997. AIT became a wholly owned subsidiary
of AFC in July 1989 in a transaction accounted for as a reverse acquisition. All
references to the "Company" hereinafter refer to the Company, AIT and NEOT GmbH
as a consolidated entity.

The Company is a development stage biopharmaceutical enterprise engaged
in the discovery and development of novel therapeutic drugs intended to treat
neurodegenerative diseases and conditions, such as memory deficits associated
with Alzheimer's disease, aging, stroke, spinal cord injuries and Parkinson's
disease. The accompanying consolidated financial statements include the results
of the Company and its wholly-owned subsidiaries.

DEVELOPMENT STAGE ENTERPRISE

The Company is in the development stage and, therefore, devotes
substantially all of its efforts to research and development activities. Since
its inception, the Company has incurred cumulative losses of approximately $23.8
million through December 31, 1998, and expects to incur substantial losses over
the next several years. While the Company believes that its existing capital
resources (including the proceeds from its line of equity financing and the
private placement of preferred stock completed in January 1999 - see Note 13)
will be adequate to fund its capital needs for at least 12 months of operations,
the Company also believes that, ultimately, it will require substantial
additional funds in order to complete the research and development activities
currently contemplated and to commercialize its proposed products. The Company's
future capital requirements and availability of capital will depend upon many
factors including, but not limited to, continued scientific progress in research
and development programs, the scope and results of preclinical studies and
clinical trials, the time and costs involved in obtaining regulatory approvals,
the costs involved in filing, prosecuting and enforcing patent claims, competing
technological developments, the cost of manufacturing scale-up, the cost of
commercialization activities and other factors which may not be within the
Company's control. Without additional funding, the Company may be required to
delay, reduce the scope of or eliminate one or more of its research and
development projects, or obtain funds through arrangements with collaborative
partners or others which may require the Company to relinquish rights to certain
technologies, product candidates or products that the Company would otherwise
seek to develop or commercialize on its own. Other factors impacting the future
success of the Company are the ability to develop products which will be safe
and effective in treating neurological diseases, and the ability to obtain
government approval as well as dependency on key personnel.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.


35
36

CASH AND EQUIVALENTS

Cash and equivalents consist of cash and highly liquid investments of
commercial paper and demand notes with original maturities of 90 days or less.
At December 31, 1997, cash equivalents of $935,000 were pledged as collateral on
a bank line of credit and were classified as restricted cash on the balance
sheet. The note was repaid and the restricted cash was released during February
1998.

PREPAID EXPENSES AND ADVANCE DEPOSITS

Prepaid expenses and advance deposits are capitalized and amortized over
the period benefitted, or as the related services are rendered (as applicable).

MARKETABLE SECURITIES

The Company accounts for investments in marketable securities under
Statements of Financial Accounting Standards ("SFAS") No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." The statement requires
investments in debt and equity securities to be classified among three
categories as follows: held-to-maturity, trading and available-for-sale. As of
December 31, 1998, all securities held by the Company were considered as
available-for-sale. Available-for-sale securities are carried at fair value,
with unrealized gains and losses reported as a separate component of
stockholders' equity. Quoted market prices have been used in determining the
fair value of these investments. Securities held-to-maturity are stated at cost,
adjusted for amortization of premiums and accretion of discounts, which are
recognized as adjustments to interest income on investment securities. A
valuation allowance is not established to recognize temporary market value
fluctuations as the Company has the intent and ability to hold these investments
until maturity. Short-term investments consist of commercial paper and
equivalent corporate obligations and are stated at amortized cost, with respect
to held-to-maturity investments, and at fair value with respect to investments
classified as available-for-sale securities.

PROPERTY AND EQUIPMENT

Property and equipment are carried at cost, less accumulated
depreciation and amortization. When property and equipment are retired or
otherwise disposed of, the related cost and accumulated depreciation are removed
from the accounts and any resulting gain or loss is reflected in income.
Depreciation and amortization are computed using principally the straight-line
method over the following estimated useful lives:

Equipment 5 to 7 Years
Leasehold Improvements The shorter of useful life or lease term

RESEARCH AND DEVELOPMENT

All costs related to research and development activities are expensed in
the period incurred.

GRANT REVENUE

Revenue consists of amounts earned from grants which are recognized in
accordance with the terms of the related agreements.

INCOME TAXES

The Company follows Statement of Financial Accounting Standards No. 109
(SFAS 109), "Accounting for Income Taxes." Under the asset and liability method
of SFAS 109, deferred tax assets and liabilities are recognized for the future
tax consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. A valuation allowance is provided for the Company's net deferred tax
asset.

STOCK BASED COMPENSATION

The Financial Accounting Standards Board issued SFAS No. 123,
"Accounting for Stock-Based Compensation" in October 1995. SFAS 123 encourages
companies to adopt a fair value approach to valuing stock options that would
require compensation cost to be recognized based on the fair value of stock
options granted. The Company has elected, as permitted by the standard, to
continue to follow its intrinsic value based method of accounting for stock
options issued to employees consistent with Accounting Principles Board (APB)

36


37
Opinion No. 25, "Accounting for Stock Issued to Employees." Under the intrinsic
method, compensation cost for stock options is measured as the excess, if any,
of the quoted market price of the Company's stock at the measurement date over
the exercise price.

NET LOSS PER SHARE

Net loss per share is calculated using the weighted average number of
shares outstanding for the period. Common stock options and warrants are
excluded from the computation as their effect would be antidilutive. In February
1997, the Financial Accounting Standards Board issued SFAS No. 128 "Earnings Per
Share," which requires companies to present basic earnings per share and diluted
earnings per share, instead of the primary and fully diluted earnings per share
(EPS) as previously required. The new standard was adopted by the Company in
1997. In 1996 the difference between previously reported EPS and restated EPS in
accordance with SFAS No. 128 amounted to an increased loss of $0.01 per share.

NEW PRONOUNCEMENTS

COMPREHENSIVE INCOME. Effective for fiscal years beginning after
December 15, 1997, SFAS No. 130 "Reporting Comprehensive Income" requires that
comprehensive income and its components, as defined in the statement, be
reported in a financial statement. Current accounting standards require that
certain items such as (1) foreign currency translation adjustments, (2)
unrealized gains and losses on certain investments in debt and equity
securities, and (3) unearned compensation expense related to stock issuances to
employees be presented as separate components of stockholders' equity, without
having been recognized in the determination of net income. Effective for fiscal
years beginning after December 15, 1997, comprehensive income must be reported
"in a financial statement that is displayed with the same prominence as other
financial statements." While the Company adopted the provisions of SFAS No. 130
for the 1998 fiscal year, the adoption of this standard did not have a material
effect on the presentation of the Company's financial statements.

SEGMENT REPORTING. SFAS No. 131, "Disclosure About Segments of an
Enterprise and Related Information" is effective for financial statements for
periods beginning after December 15, 1997. SFAS No. 131 replaces SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise" and several other
pronouncements that amended SFAS No. 14. SFAS No. 131 requires the disclosure of
extensive information about an entity's operating segments. In addition to
disclosure of information about multiple reporting segments, an enterprise is
required to report certain disaggregated information, even if it functions as a
single operating unit. Management believes that the Company currently operates
under a single segment. Adoption of SFAS No. 131 in 1998 did not materially
impact the Company's financial statement disclosures.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities. The Statement establishes accounting and reporting
standards requiring that every derivative instrument (including certain
derivative instruments embedded in other contracts) be recorded in the balance
sheet as either an asset or liability measured at its fair value. The Statement
requires that changes in the derivative's fair value be recognized currently in
earnings unless specific hedge accounting criteria are met. Statement 133 is
effective for fiscal years beginning after June 15, 1999, although earlier
implementation is allowed. Management plans to adopt the Standard in fiscal 2000
and believes that its adoption will not have a material impact on the Company.

USE OF ESTIMATES

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

2. RELATED PARTY TRANSACTIONS

During 1987 and 1988, the Company's Chief Executive Officer, who is also
a major stockholder of the Company, loaned a total of $270,650 to the Company
for working capital purposes, of which $250,000 plus $2,000 of accrued interest
was canceled in December 1988 in exchange for the issuance of 28 Revenue
Participation Units ("RPU's"). The RPU's, in turn, were converted into 112,000
shares of common stock (see Note 8).

From 1989 through 1993 the Company borrowed an additional $757,900 from
the Chief Executive Officer which, together with accrued interest of $300,404,
aggregated $1,058,304 on December 31, 1993, at which time the Company issued
200,000 shares of common stock to the Chief Executive Officer in exchange for
cancellation of $500,000 of loans made to the Company. The remaining $257,900 in
principal and accrued interest of $300,404 were converted to a $558,304
promissory note which, as amended from time to time, is currently unsecured, and
is payable upon demand. Interest is payable monthly at the annual rate of 9%.


37


38

In September 1990, the Company issued a warrant to the Chief Executive
Officer to purchase up to 88,173 shares of common stock of the Company at any
time between September 1, 1990 and August 31, 1995, for $3.75 per share.
Effective August 31, 1995, the expiration date of the warrant was extended to
August 31, 2000.

ASSIGNMENT OF PATENTS BY CHIEF EXECUTIVE OFFICER

The Chief Executive Officer of the Company has assigned all of his
rights in the following three patents to the Company:

1. U.S. Patent No. 5,091,432 issued on February 25, 1992;
2. U.S. Patent No. 5,447,939 issued on September 5, 1995; and
3. U.S. Patent No. 5,801,184 issued on September 1, 1998.

In connection with the assignment of these patents to the Company, the
Chief Executive Officer and the Company entered into royalty agreements, which
expire concurrently with the expiration of the underlying patents and any
patents derived therefrom. Under each of the Agreements, as amended, the Company
is obligated to pay the Chief Executive Officer a royalty of two percent (2%) of
all revenues derived by the Company from the use and sale by the Company of any
products or methods included in the patents. Further, in the event that the
Chief Executive Officer's employment is terminated by the Company without cause,
the royalty rate under each Agreement was to be increased to five percent (5%).
Finally, in the event of the Chief Executive Officer's death, the family or
estate is entitled to continue to receive under each Agreement royalties at a
rate of two percent (2%) for the duration of the respective Agreement.

MCMASTER UNIVERSITY AGREEMENT

On July 10, 1996, the Company entered into a license agreement with
McMaster University (the "University") which allows the Company use of certain
chemical compounds developed by the University covered in the patents filed
jointly by the Company and the University. Under the agreement, the Company paid
a one time licensing fee of $15,000 and is obligated to pay an annual royalty of
five percent (5%) on net sales of products containing compounds developed by the
University. The Company commenced payment of minimum annual royalties of $25,000
beginning July 1997. A second payment of $25,000 was made in July 1998. The
third patent noted above was also jointly filed by the Company and the
University and is subject to the same royalty agreement.

EMPLOYMENT AGREEMENT

Effective July 1, 1996, the Company entered into an employment agreement
with the Chief Executive Officer. The agreement, among other things, provides
for the grant of incentive stock options, an annual base salary with annual
increases and an annual bonus based on the Company's attainment of certain
performance objectives. The agreement, which was originally scheduled to
terminate on June 30, 1999, was extended to December 31, 1999. The agreement
also provides for guaranteed severance payments upon the Chief Executive
Officer's termination of employment without cause, or upon a change of control
of the Company. In connection with entering into this agreement, the Chief
Executive Officer was granted an incentive option to purchase 75,000 shares of
common stock at 110 percent of fair market value at the date of grant ($4.13 per
share). This option vests in three equal increments over the life of the
original agreement.

4. DEBT

During August 1997, the Company established a Line of Credit Agreement
with its bank which expired August 30, 1998. At December 31, 1997, the Company
was indebted to the bank for $850,000 under the Agreement. The interest rate was
approximately 8% at December 31, 1997. Such debt was collateralized by
restricted cash equivalents in the amount of $935,000. During February 1998 the
related note was repaid and the restricted cash was released.

In September 1997, the Company financed the premium for a three year
insurance policy through a borrowing from the insurer. The loan is payable
through August 2000 in monthly installments of $9,475, including principal and
8.25% interest.

In September 1998, the Company entered into a $2 million Master Note and
Security Agreement (the "Note") with a finance company affiliated with its bank.
Through December 31, 1998, the Company borrowed $1,500,000 under the Note for
equipment and computer software purchases and has an additional $500,000

39

available over the next year for similar purchases. Borrowings are
collateralized by substantially all of the Company's assets, exclusive of its
patents and other intellectual properties. The note requires monthly repayments
of $41,277, bears interest at approximately 12% and is due March 2002, at which
time a final principal installment of $150,000 is due. The Company has also
granted to the finance company a warrant to purchase up to 13,459 shares of its
common stock at $7.43 a share which was valued at $45,000 using the
Black-Scholes option-pricing model with the following assumptions: Risk-free
interest rate of 5.02 percent; expected life of three years; expected volatility
of 75.3 percent. The warrant was recorded as a prepaid expense and is being
amortized with the effective interest method over the life of the note.

Future installments of debt principal are as follows:

5. REVENUE FROM GRANTS

In July 1995, a Small Business Innovative Research Grant (the SBIR
Grant) from the National Institutes of Health was completed and no additional
funds were due or collected. The Company has received an aggregate of $497,128
from the SBIR Grant.

6. PROVISION FOR INCOME TAXES

No provision for federal and state income taxes has been recorded, as
the Company has incurred net operating losses through December 31, 1998. At
December 31, 1998, the Company and its domestic subsidiary had approximately
$14.7 million of federal net operating loss carryforwards available to offset
future United States taxable income, if any. Such carryforwards expire on
various dates beginning 2009 through 2018. The primary differences between the
tax and financial reporting basis of assets and liabilities is the
capitalization of certain start-up expenses for income tax reporting purposes
which are expensed for financial reporting purposes. Under the Tax Reform Act of
1986, the amounts of and benefits from net operating losses carried forward may
be impaired or limited in certain circumstances. Events which may cause
limitations in the amount of net operating losses that the Company may utilize
in any one year include but are not limited to, a cumulative ownership change of
more than 50 percent over a three year period. At December 31, 1998, the effect
of such limitation, if imposed, has not been determined. The Company's foreign
subsidiary has a loss carryforward of approximately $5.0 million at December 31,
1998, resulting principally from the transfer of licensing rights by the Parent
to the foreign subsidiary and from the Parent Company's allocation of research
and development costs to the foreign subsidiary during the period April 1997
through December 1998. The Company has recognized a valuation allowance for the
full amount of the deferred tax benefit arising from these net operating losses
due to the uncertainty of its realization.

7. COMMITMENTS AND CONTINGENCIES

FACILITY LEASES

During late June 1997, the Company relocated to a new facility, which it
leases from a property developer under a non-cancelable operating lease expiring
in June 2004. The lease requires monthly rent payments ranging from $38,800 to
$47,600, plus cost of living adjustments (as defined, including certain minimum
increases) over its term, property taxes, insurance and maintenance
reimbursements. The lease contains two five year options to renew at fair value
rates in effect at the time of renewal. In addition, the Company leases certain
office and telephone equipment under non-cancelable operating leases expiring in
2002. Minimum lease requirements for each of the next five years and thereafter
under the aforementioned property and equipment leases follows:

Years ending December 31:
1999 $ 501,600
2000 517,800
2001 513,400
2002 542,100
2003 554,200
2004 285,400
----------
$2,914,500
==========

Rent expense for the years ended December 31, 1996 and 1997 and 1998
aggregated approximately $26,800, $372,000 and $572,400 and respectively.

RESEARCH AND FELLOWSHIP GRANTS

At December 31, 1998, the Company has committed to pay approximately
$570,000 to a number of universities to conduct general scientific research
programs and $50,000 to the Reeve-Irvine Research Center at The University of
California Irvine, to provide for a Fellowship Grant. Payment of these grants
and the fellowship is anticipated to amount to approximately $442,000 and
$178,000 in 1999 and 2000, respectively. Grant expense for 1996, 1997 and 1998
amounted to approximately $60,500, $335,000 and $465,900, respectively.

MAJOR CLINICAL TRIAL

In October 1998 the Company entered into an agreement with a contract
research organization to conduct a clinical trial in three countries involving
approximately 400 patients. The agreement, which is cancelable by either party
upon thirty days notice, is expected to result in aggregate expenditures ranging
from $4 to $5 million over the course of one year. Through December 31, 1998,
the Company had expended approximately $360,000 in connection with this clinical
trial, of which approximately $265,000 was reflected as an advance at December
31, 1998, for services to be rendered in 1999.

LITIGATION

On December 10, 1998, the Company was served with a lawsuit initiated by
four former employees of the Company. The lawsuit, which was filed in the
Superior Court of Orange County, California, also names Dr. Alvin J. Glasky, the
Company's founder and Chief Executive Officer, as a defendant. The lawsuit
arises from a dispute concerning the termination, as of December 31, 1997, of
agreements entered into as of June 1990 and December 1993 between the Company
and each of the former employees, pursuant to which the employees agreed to
accept an aggregate of 278,589 shares of the Company's common stock, subject to
forfeiture provisions, in exchange for the cancellation of indebtedness owed to
them by the Company arising from unpaid compensation and expenses in the total
amount of $458,411. Pursuant to the agreements, the employees were not entitled
to keep the shares unless the Company achieved certain revenue goals by a
specified date, as determined by the Company's independent auditors in
accordance with generally accepted accounting principles. Under the agreements,
as amended, the Company was required to achieve total operating revenues from
the date of each agreement through December 31, 1995, in a cumulative amount of
at least $500,000. When the Company failed to achieve this goal, the agreements
were amended to extend the deadline until December 31, 1997 and increase the
revenue goal to a cumulative amount of at least $1,000,000. The agreements
provide that, if the revenue goals are not achieved by the stated deadline, the
shares will be forfeited and the employees will be required to return the shares
to the Company. The Company did not achieve the required revenue goals either by
December 31,1995, or by December 31, 1997. The Company's total revenues from
inception through December 31, 1995, were only $497,128. The Company did not
have any revenues in 1996 or 1997, and the total revenues from inception through
December 31, 1997 remained at $497,128. In the lawsuit the plaintiffs allege,
among other things, that the cumulative revenues of the Company were or should
have been in excess of $500,000 as of December 31, 1995, and that the defendants
fraudulently induced the plaintiffs into entering into the agreements and the
subsequent amendments to the agreements. The lawsuit asks for damages in excess
of $4,000,000 or, in the alternative, that the forfeiture restrictions be
removed and the plaintiffs be allowed to keep their shares of common stock. The
plaintiffs are also seeking punitive damages and reimbursement of attorneys'
fees and costs. In March 1999, the Company filed a cross-complaint against the
plaintiffs to seek a determination that the plaintiffs' shares have in fact been
forfeited, and to obtain a court order requiring the plaintiffs to return their
shares to the Company for cancellation. The lawsuit is in the early stages of
discovery and no trial date has been set. Management of the Company believes
that the plaintiffs' claims are without merit and that the resolution of this
matter will not have a material adverse effect on the financial condition or
operations of the Company. The Company intends to vigorously defend the lawsuit
and to pursue the cross-complaint for the return and cancellation of all of the
disputed shares. At the same time that the plaintiffs entered into their
agreement with the Company in 1990 and 1993, Dr. Alvin J. Glasky and his wife,
who was then and is now an employee of the Company, also entered into
agreements with the Company that were identical to those entered into by the
plaintiffs, pursuant to which Dr. and Mrs. Glasky received an aggregate of
400,244 shares of common stock subject to identical forfeiture provisions, in
exchange for the cancellation of indebtedness owed to them by the Company
arising from unpaid compensation and expenses in the total amount of $755,531.
Dr. and Mrs. Glasky entered into an agreement with the Company on December 21,
1998, pursuant to which they have agreed to surrender for cancellation the same
proportion of their restricted shares as the plaintiffs are required to
surrender based on the final resolution of the lawsuit. Because the suit is in
its early stages, counsel for the Company is unable to opine on the merits of
the suit. However, management intends to defend the action, which it believes is
without merit, and to vigorously pursue the return and cancellation of all of
the disputed shares. Until such time as the matter is finally resolved, the
Company is continuing to account for all of the shares, which it has deemed
forfeited, as issued and outstanding.

8. STOCKHOLDERS' EQUITY

REVENUE PARTICIPATION UNITS

In 1988 and 1989, AIT raised private placement funds via a financial
instrument specified as a Revenue Participation Unit ("RPU"). The Company raised
an aggregate of $676,000 from the issuance of seventy-five RPU's at prices
ranging from $9,000 to $10,000 per RPU. The RPU's entitled holders to cash
payments based on stipulated percentages of revenues. Holders of RPU's were
entitled to convert to common stock at any time and AIT had the option to redeem
the RPU's subject to certain conditions by paying cash or in exchange for common
stock.

In July 1996, the Company offered, and all RPU holders accepted, an
option to convert each RPU unit into 4,000 shares of common stock (300,000
shares in the aggregate) in exchange for waiving all rights as an RPU holder.

REVERSE STOCK SPLIT

In June 1996, the Board of Directors authorized, with shareholder
approval, a reverse split of the Company's outstanding common stock on the basis
of 1 share for each 2.5 shares of the then outstanding common stock. The Board
of Directors also authorized, with shareholder approval, an increase in the
authorized common stock from 10 million to 25 million shares and the creation of
a new class of preferred stock with the authorization to issue up to 5 million
shares of such preferred stock. All references to common stock amounts and loss
per share in the accompanying financial statements give effect to the reverse
stock split.

RE-INCORPORATION

During June 1997, the stockholders of the Company approved the
re-incorporation of the Company as a Delaware corporation. In connection
therewith, a par value of $0.001 per share was assigned to the common stock of
the Company. The total number of authorized and issued shares remained
unchanged.

COMMON STOCK

During 1993, the Company issued to a financial consultant in exchange
for investment banking services, 40,000 shares of common stock at $1.35 per
share, the market value on issuance date, for an aggregate amount of $54,000.

During 1994, three investors bought 13,000 shares of restricted
(restrictions as to transferability) common stock at $2.50 per share, for an
aggregate amount of $32,500, through a private placement. During 1995, six
investors bought 22,000 shares of restricted common stock at $2.50 per share,
for an aggregate amount of $55,000, through a private placement.

From January 1, 1996, to June 20, 1996, 266,800 shares of restricted
(restrictions as to transferability) common stock were issued at $2.50 per
share, for an aggregate amount of $633,650 (net of commission), through a
private placement.

In June 1996, the Company filed a registration statement with the
Securities and Exchange Commission offering to the public 2,500,000 units (the
"Units"), each Unit consisting of one share of the Company's common stock (the
"common stock"), and one warrant to purchase one share of common stock (the
"warrants"). The registration statement became effective on September 26, 1996,
and on October 1, 1996, the Company realized $17,363,003 in net proceeds from
the sale of the 2,500,000 Units.

On October 11, 1996, the principal underwriter of the offering exercised
a portion of its overallotment option and purchased 200,000 Units for net cash
of $1,389,280. The Units separated immediately following issuance and the common
stock and warrants that made up the Units trade only as separate securities.

On March 27, 1998, the Company executed a $15 million Private Equity
Line of Credit Agreement (the "Agreement") with a private investor. The
Agreement provides for the Company, at its sole discretion, and subject to
certain restrictions, to periodically sell ("put") shares of its common stock to
the investor. Puts can be made every 15 days in amounts ranging from $250,000

42

43
to $2,000,000, depending on the trading volume and the market price of the
stock at the time of each put, subject to aggregate minimum puts of $1 million
over the life of the Agreement. At the time of each put, the investor receives a
discount of 12% from the then current average market price, as determined under
the Agreement. Pursuant to the Agreement, the Company also issued to the
investor warrants to purchase 25,000 shares of common stock at $11.62 per share.
As of December 31, 1998, the Company had put a total of 506,049 shares of its
common stock to the investor pursuant to the Agreement resulting in net proceeds
of approximately $3,452,000.

On August 31, 1998, certain officers and directors of the Company
exercised non-qualified stock options and purchased 62,000 shares of common
stock. The exercise price of the stock options was at $4.50 per share for 50,000
shares and $5.13 per share for 12,000 shares for an aggregate purchase price of
$286,560, represented by notes issued by the purchasers. The notes are full
recourse promissory notes bearing interest at 7% and are collateralized by the
stock issued upon the exercise of the stock options. Interest and principal are
payable two years after the issue dates. The notes have been offset against the
underlying common stock in the accompanying financial statements.

9. STOCK OPTIONS

The Company has two stock option plans: the 1991 Stock Incentive Plan
(the "1991 Plan") and the 1997 Stock Incentive Plan (collectively, the "Plans").
The Plans were adopted by the Company's shareholders and Board of Directors in
May 1991 and June 1997, respectively, and provide for the granting of incentive
and nonqualified stock options as well as other stock-based compensation. The
1991 Plan, as amended, authorizes for issuance up to 401,430 shares of the
Company's common stock. Options which have been granted under the 1991 Plan
contain vesting provisions determined by the Board of Directors which range from
one to four years. The 1997 Plan authorizes for issuance up to 500,000 shares of
the Company's common stock. Under the Plans, shares of the Company's common
stock may be granted to directors, officers and employees of the Company, except
that incentive stock options may not be granted to non-employee directors.

The Plans provide for issuance of incentive stock options having
exercise prices equal to the fair market values of the stock at the times of
grant of the options or, in certain circumstances, at option prices at least
equal to 110 percent of the fair market value of the stock at the time the
options are granted. An option granted under the Plans is exercisable in such a
manner and within such period, not to exceed ten years from the date of the
grant, as shall be set forth in a stock option agreement between the employee
and the Company.

Stock options have also been issued outside of the aforementioned plans
to various consultants. During the period of December 1993 through December
1996, the Company issued a total of 194,000 options to purchase common stock to
two technical consultants and a financial consultant in exchange for past and
future services. The options are exercisable through December 31, 2001, at an
exercise price of $0.025 per share. As the exercise price was lower than the
fair market value of the stock on the date the options were granted,
compensation expense was recorded for the difference between the option exercise
price and the estimated fair market value of the stock as determined by the
Board of Directors on the grant date. All options and warrants issued outside of
the Plan were vested and exercisable upon issuance. In September 1990, the
Company issued a warrant to the Chief Executive Officer of the Company to
purchase 88,173 shares of common stock at $3.75 per share. The warrant expires
August 31, 2000.

In January 1997, the Company issued to a financial consultant, 10-year
options to purchase 180,000 shares of the Company's common stock at an exercise
price of $3.875 per share, of which 30,000 options vested immediately. In
November 1998, the Company issued to the same financial consultant additional
10-year options to purchase 25,000 shares of the Company's common stock at an
exercise price of $8.5625 per share, all of which vested immediately. The
Company recognized $103,950, $60,000 and $422,264 of compensation expense for
these options in 1996, 1997 and 1998, respectively. Compensation expense was
determined in accordance with SFAS No. 123, with the fair values determined
using the Black-Scholes option-pricing model at the original grant dates.
Management believes that the fair value results using calculations over the
respective vesting periods of these options would not have been materially
different.

The following table summarizes information about stock options

5.626 to 12.88 382,200 8.89 8.53 162,375 9.16


As of December 31, 1998, there were 349,700 options outstanding under
the 1997 Plan and 181,000 options outstanding under the 1991 Plan. The remaining
323,173 outstanding options were granted outside of option plans.

The Company applies APB Opinion No. 25 and related interpretations in
accounting for stock options granted to employees, and does not recognize
compensation expense when the exercise price of the options equals the fair
market value of the underlying shares at the date of grant. Directors' stock
options are treated in the same manner as employee stock options for accounting
purposes. Under SFAS No. 123, the Company is required to present certain pro
forma earnings information determined as if employee stock options were
accounted for under the fair value method of that statement.

The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1996, 1997 and 1998, respectively: risk-free
interest rates of 6.52% (1996), 6.37% (1997) and 4.96% (1998); zero expected
dividend yields; expected lives of 5 years; expected volatility of 50 percent in
1996 and 1997, and 75.26 percent in 1998.

For purposes of the following required pro forma information, the
weighted average fair value of stock options granted in 1996, 1997 and 1998 was
$2.14, $3.06 and $4.96, respectively. The total estimated fair value is
amortized to expense over the vesting period.

10. SALARY DEFERRAL PLAN

The Company established a 401(k) Salary Deferral Plan on January 1,
1990. The Plan allows eligible employees to defer part of their income on a
tax-free basis. Contributions by the Company to the Plan are discretionary upon
approval by the Board of Directors. To date, the Company has not made any
contributions into the Plan.

11. RESEARCH ACTIVITIES

During 1995, the National Institute on Aging (NIA) and the National
Institute for Mental Health (NIMH) issued contracts to an independent
subcontractor of theirs to manufacture AIT-082 for animal and human testing
programs. The NIA also issued an additional contract to one of its
subcontractors to conduct the subchronic animal toxicity studies required by the
U.S. Food and Drug Administration as a part of an Investigational New Drug (IND)
application for AIT-082. The entire cost of these two contracts was funded by
the NIA and NIMH directly to the subcontractors.

13. EVENTS SUBSEQUENT TO DECEMBER 31, 1998

On January 29, 1999, the Company entered into an agreement with two
private investors to sell up to $6 million of 5% preferred stock, with rights of
conversion into common stock. The financing consists of two tranches of
preferred stock. The first tranche of $4.0 million was sold on January 29, 1999,
and for an initial period of 120 days is convertible into common stock at a
fixed price of $13.06 per share. Thereafter, the preferred stock is convertible
at the lesser of the fixed price or a variable rate of 101% of the average of
the ten lowest closing bid prices of the common stock during the thirty days
immediately preceding the conversion date. In no event can the first tranche be
converted into more than 1,450,000 shares. The second tranche of $2.0 million,
which is at the Company's option, can be sold approximately 6 months after the
effective date of the Preferred Stock Agreement, subject to the satisfaction by
the Company of certain conditions. The preferred stock in the second tranche
will contain terms and conditions for conversion similar to the first tranche,
except that the fixed conversion price will be set at 125% of the average market
price of the common stock at the time of the second closing. Dividends on the
preferred stock are payable in cash or in common stock, at the option of the
Company, at the annual rate of 5%. Additional features of the preferred stock
issue include, among other things, a redemption feature at the Company's option
if the common stock trades below a floor of $5 per share or above a ceiling of
$20 per share. The investors also received warrants to purchase for a period of
5 years, 75,000 shares of the Company's common stock at $12.98 per share.

EMPLOYMENT AGREEMENT

The Company has an employment agreement with Dr. Alvin J. Glasky,
effective as of July 1, 1996. The agreement requires Dr. Glasky to devote all of
his productive time, attention, knowledge and skill to the affairs of the
Company during the term of the agreement. The agreement provides for an annual
base salary of $200,000 with annual increases and an annual bonus based on the
Company's attainment of certain performance objectives. The agreement, as
amended, ends on December 31, 1999, and may be terminated by the Company with or
without cause as defined in the agreement. The agreement also provides for
guaranteed severance payments equal to Dr. Glasky's annual base salary over the
remaining life of the agreement upon the termination of employment without cause
or upon a change in control of the Company. In connection with entering into
this agreement, Dr. Glasky was granted an incentive stock option to purchase
75,000 shares of common stock at an exercise price of $4.13 per share, which
vests in three equal annual increments.

COMPENSATION OF DIRECTORS

Each of the Company's non-employee directors receives $1,000 for each
Board of Directors meeting and $500 for each committee meeting attended (with
the Chairperson of the Committee receiving $1,000). The directors are also
reimbursed for certain expenses in connection with attendance at Board meetings.
In February 1998, the Company granted to each non-employee director an option to
purchase 10,000 shares of common stock at $8.375 per share. In August 1998, the
Company granted to each non-employee director an option to purchase 10,000
shares of common stock at $5.625 per share.

STOCK OPTION PLANS

The Company has two stock option plans: the 1991 Stock Incentive Plan
(the "1991 Plan") and the 1997 Stock Incentive Plan (the "1997 Plan") (the
"Plans"). The Plans were adopted by the Company's shareholders and Board of
Directors in May 1991 and June 17, 1997, respectively.

THE 1991 INCENTIVE STOCK OPTION PLAN

The 1991 Plan, as amended, provides for grants of "incentive stock
options" within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"), nonqualified stock options, stock appreciation rights
("SARs") and bonus stock. The 1991 Plan, as amended, authorizes for issuance up
to 401,430 shares of the Company's common stock. Under the 1991 Plan, incentive
stock options may be granted to employees, and nonqualified stock options, SARs
and bonus stock may be granted to employees of the Company and other persons
whose participation in the 1991 Plan is determined to be in the Company's best
interest. As of December 31, 1998, there were options to purchase 181,000 shares
of common stock outstanding under the 1991 Plan.

THE 1997 INCENTIVE STOCK OPTION PLAN

The 1997 Plan provides for grants of "incentive stock options" within
the meaning of the Code, nonqualified stock options and rights to purchase
shares of common stock ("Purchase Rights"). The 1997 Plan authorized for
issuance up to 500,000 shares of the Company's common stock, subject to
adjustment in the number and kind of shares subject to the 1997 Plan and

51


52
to outstanding shares in the event of stock splits, stock dividends or certain
other similar changes in the capital structure of the Company. Under the 1997
Plan, incentive stock options, nonqualified stock options and Purchase Rights
may be granted to employees of the Company and its subsidiaries and affiliates.
Nonqualified stock options and Purchase Rights may be granted to employees of
the Company and its subsidiaries and affiliates, non-employee directors and
officers, consultants and other service providers. As of December 31, 1998,
there were options to purchase 349,700 shares of common stock outstanding under
the 1997 Plan.

The Plans are administered by a Compensation Committee appointed by the
Board of Directors (the "Committee"), which has sole discretion and authority,
consistent with the provisions of the Plans, to determine which eligible
participants will receive options, the time when options will be granted, the
terms of options granted and the number of shares which will be subject to
options granted under the Plans.

In the event of a merger of the Company with or into another corporation
or the sale of substantially all of the assets of the Company, all outstanding
options and SARs granted under the Plans shall be assumed or equivalent options
and SARs substituted by the successor corporation. In the event a successor
corporation does not assume or substitute the options and SARs, the
exercisability of the options and SARs under the 1991 Plan shall be accelerated.
The exercisability of options outstanding under the 1997 Plan will accelerate
upon a change in control of the Company, regardless of whether the options are
assumed or new options are issued by the successor corporation.

The exercise price of incentive stock options must be not less than the
fair market value of a share of common stock on the date that the option is
granted (110% with respect to optionees who own at least 10% of the outstanding
common stock). Nonqualified options shall have such exercise price as determined
by the Committee. The Committee has the authority to determine the time or times
at which options granted under the Plans become exercisable, provided that
options expire no later than ten years from the date of grant (five years with
respect to optionees who own at least 10% of the outstanding common stock).
Options are nontransferable, other than upon death, by will and the laws of
descent and distribution, and incentive stock options may be exercised only by
an employee while employed by the Company or within three months after
termination of employment (one year for termination resulting from death or
disability).

SECTION 401(K) PLAN

In January 1990, the Company adopted the AIT Cash or Deferred Profit
Sharing Plan (the "401(k) Plan") covering the Company's full-time employees
located in the United States. The 401(k) Plan is intended to qualify under
Section 401(k) of the Code, so that contributions to the 401(k) Plan by
employees or by the Company, and the investment earnings thereon, are not
taxable to employees until withdrawn from the 401(k) Plan, and so that
contributions by the Company, if any, will be deductible by the Company when
made. Pursuant to the 401(k) Plan, employees may elect to reduce their current
compensation by up to the statutorily prescribed annual limit ($10,000 in 1998)
and to have the amount of such reduction contributed to the 401(k) Plan. The
401(k) Plan permits, but does not require, additional matching contributions to
the 401(k) Plan by the Company on behalf of all participants in the 401(k) Plan.
The Company has not made any contributions to the 401(k) Plan.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

In September 1990, the Company issued a warrant to Dr. Alvin J. Glasky
(the "Glasky warrant") to purchase up to 88,173 shares of common stock of the
Company at any time between September 1, 1990, and August 31, 1995, for $3.75
per share. Effective August 31, 1995, the expiration date of the Glasky warrant
was extended to August 31, 2000.

On June 30, 1990, in exchange for cancellation of $503,144 of
indebtedness for unpaid compensation, the Company issued a total of 402,517
shares of common stock in the following amounts: Dr. Alvin Glasky, 184,000
shares; Sanford Glasky (the brother of Dr. Alvin Glasky), 60,013 shares; JoAnne
Law, 24,333 shares; Luana Kruse, 19,200 shares; Rosalie Glasky (the wife of Dr.
Glasky), 28,065 shares; and John W. Baldridge, 86,906 shares (the "1990
Restricted Stock Exchange"). On December 30, 1993, in exchange for cancellation
of $690,798 of indebtedness for unpaid compensation and accrued expenses, the
Company issued a total of 276,317 shares of common stock in the following
amounts: Dr. Alvin Glasky, 169,001 shares; Sanford Glasky, 49,837 shares; JoAnne
Law, 16,559 shares; Luana Kruse, 19,800 shares; Rosalie Glasky, 19,178 shares;
and John W. Baldridge, 1,942 shares (the "1993 Restricted Stock Exchange"). Both
the 1990 Restricted Stock Exchange and the 1993 Restricted Stock Exchange
involved a risk of forfeiture whereby if the Company did not generate a minimum
of $500,000 in total operating revenues from inception through December 31,
1995, all shares would be returned to the Company with the holders forfeiting
all rights to the shares and forfeiting any claim to the previously accrued but
unpaid compensation. Effective December 31, 1995, five of the parties, all of
whom were present or past employees of the Company, entered into agreements with
the Company whereby the forfeiture date was extended from December 31, 1995 to
December 31, 1997 in exchange for increasing the minimum total operating
revenues which the Company would need to achieve in order to avoid forfeiture of
the shares from $500,000 to $1,000,000, with such revenues to be achieved by
December 31, 1997. As of December 31, 1997, when the Agreements terminated, the
Company did not achieve the revenue goals set forth in the Agreements, as
previously amended. The four former employees who are parties to the Agreements
have indicated disagreement with the Company's position and have filed a lawsuit
against the Company seeking a determination that they are entitled to keep their
shares. The Company has filed a cross-complaint against the four former
employees seeking the return and cancellation of the shares. The Company's Chief
Executive Officer and his wife have agreed to surrender to the Company for
cancellation the same proportion of their shares (a total of 400,244) as the
four former employees are required to surrender based on the final resolution of
the lawsuit. Until such time as the Company can obtain the surrender of all of
these shares and the matter is fully resolved, the Company is accounting for all
of the stock, which it has deemed forfeited, as issued and outstanding.

On June 6, 1991, the Company entered into an agreement (the "1991 Patent
Agreement") with Dr. Alvin Glasky whereby Dr. Glasky assigned to the Company all
rights to the inventions covered by United States Patent No. 5,091,432 and any
corresponding foreign applications and patents, including all continuations,
divisions, reissues and renewals of said applications and any patents issued out
of or based upon said applications (the "Assigned Rights"). The 1991 Patent
Agreement was amended on July 26, 1996. The 1991 Patent Agreement, as amended,
calls for the Company to pay Dr. Glasky a two percent royalty on all revenues
derived by the Company from the use and sale by the Company of any products
covered by these patents and applications or any patents derived from them. In
the event that Dr. Glasky's employment is terminated by the Company without
cause, the royalty rate shall be increased to five percent and in the event that
Dr. Glasky dies during the term of the 1991 Patent Agreement, Dr. Glasky's
family or estate shall be entitled to continue to receive royalties at the rate
of two percent. The 1991 Patent Agreement terminates on the later of its ten
year anniversary or the expiration of the final patent included within the
Assigned Rights. On June 30, 1996, the Company and Dr. Glasky entered into an
agreement whereby Dr. Glasky assigned to AIT all rights to the inventions


54


55
covered by United States Patent No. 5,447,939 (the "1996 Patent Agreement"). The
scope of the 1996 Patent Agreement as well as its terms and conditions are
identical in all material respects to the 1991 Patent Agreement; provided,
however, that the aggregate royalty amount with respect to any product shall be
two percent (five percent in the event of termination without cause), even if a
product is based on both patents. The 1996 Patent Agreement was also amended on
July 26, 1996. Dr. Glasky will not receive any royalties with respect to sales
of products which utilize patent rights licenses to the Company by McMaster
University. A third patent, which was issued September 1, 1998, is also subject
to the royalty provisions of the 1996 Patent Agreement. See "ITEM 1 - Business -
Patents and Proprietary Rights."

On December 31, 1993, the Company issued 200,000 shares of common stock
to Dr. Glasky in exchange for cancellation of $500,000 of indebtedness for loans
made by Dr. Glasky to the Company. Dr. Glasky received certain registration
rights with respect to these shares. The remaining $257,900 in principal on the
loans payable and accrued interest of $300,404 due to Dr. Glasky were converted
into a $558,304 promissory note which, as amended from time to time, is
currently unsecured, bears interest at 9% per annum, and is payable upon demand.
