AND ORAL FORWARD-LOOKING STATEMENTS ATTRIBUTABLE TO THE COMPANY OR PERSONS
ACTING ON ITS BEHALF ARE EXPRESSLY QUALIFIED IN THEIR ENTIRETY BY THESE
CAUTIONARY STATEMENTS. READERS ARE ALSO URGED TO CAREFULLY REVIEW AND CONSIDER
THE VARIOUS DISCLOSURES MADE BY THE COMPANY, IN THIS DOCUMENT, AS WELL AS THE
COMPANY'S PERIODIC REPORTS ON FORMS 10-K, 10-Q AND 8-K FILED WITH THE SECURITIES
AND EXCHANGE COMMISSION ("SEC").

MacroChem develops pharmaceutical products for commercialization by
employing SEPA(R) (Soft Enhancer of Percutaneous Absorption), our patented
topical drug delivery technology. SEPA compounds, when properly combined with
drugs, provide pharmaceutical formulations, such as creams, gels, lacquers and
solutions, etc., that enhance the transdermal delivery of drugs into the skin or
into the bloodstream. We believe that SEPA compounds enhance the diffusion of
drugs into and through the skin by making the outer layer of the skin more
permeable to the drug molecule. Transdermal delivery provides an alternative to
other methods of drug administration, such as injection, oral dosage forms and
inhalation, and may allow selected drugs to be administered more effectively, at
lower doses, with fewer adverse events and with improved patient compliance for
both human and veterinary use.

We are developing specific SEPA formulations for use with non-proprietary
and proprietary drugs manufactured by pharmaceutical companies, and we plan to
commercialize these products through the formation of partnerships, strategic
alliances and licensing arrangements with those companies. In order to attract
strategic partners, we are conducting clinical testing of SEPA-enhanced
pharmaceuticals. Because of the substantial costs involved in bringing a new
pharmaceutical product, or a new formulation of an old drug, to market, we may
be required to rely on pharmaceutical companies to conduct all or part of the
clinical trials necessary to gain regulatory approval to manufacture and to
market any resulting product.

We have also developed a series of new low molecular weight polymers,
termed MacroDerm(TM), for cosmetic use and the topical delivery of
pharmaceuticals. We have developed, tested and evaluated MacroDerm prototypes
and are seeking strategic partners to manufacture and market products based upon
this technology.

We do not maintain general product liability insurance, since we do not
market drug products. We have ongoing clinical studies and have obtained
specific liability insurance relating to our studies. As of December 31, 2001,
no liability claims had been asserted against us. However, in the future,
incidents could give rise to claims which could exceed our insurance coverage
and resources.

RESEARCH AND DEVELOPMENT

We conduct our research and development activities through our own staff
and facilities, and also through collaborative arrangements with universities,
contract research organizations and independent consultants. As of March 1,
2002, the Company had 32 full-time employees, 21 of whom are devoted to research
and development and regulatory affairs. Research and developmental expenditures
were $9,791,400, $5,280,600 and $5,423,100 during the years ended December 31,
2001, 2000 and 1999, respectively. We also rely upon third parties to conduct
clinical studies, obtain U.S. Food and Drug Administration ("FDA") and other
regulatory approvals and manufacture and market a finished product.

We conduct stability studies, test our unique formulations and design
manufacturing processes for our SEPA compounds and polymer technologies at our
facility and other facilities. We have cGMP (current Good Manufacturing
Practices) facilities for the manufacture of dosage forms for clinical
evaluations.

PRODUCTS AND TECHNOLOGIES

BACKGROUND

To be effective, drugs must reach an intended site in the body, at an
effective concentration, and for an appropriate length of time. Traditional
methods of drug administration, such as oral ingestion, intramuscular and
intravenous injections and inhalation, are effective for a wide variety of
drugs. However, depending upon the given drug, each method may have
disadvantages. For example, following oral administration, a drug must pass
through the gastrointestinal system to be absorbed and may be metabolized or
broken down in the stomach, intestines or liver, resulting in a lower amount of
unchanged drug at the target site for its action. As a result, higher dosages of
the drug must be administered orally to produce the desired effect, which may
cause irritation of the gastrointestinal tract and systemic toxicity.

In addition, the rate at which an orally administered drug is absorbed may
vary depending on several factors, including the drug's chemical properties, the
length of time the drug remains in the gastrointestinal tract and the patient's
meal patterns. The pharmaceutical industry has investigated a variety of
alternative approaches for dealing with drug adverse events and loss of efficacy
following oral dosing, including enteric coating of tablets, formulating with
various waxes and cellulosic materials, microencapsulation and compressing
tablets in various layers. However, the desired effects of these approaches are
not always reproducible from patient to patient or effective in bypassing
metabolism.

TOPICAL DRUG DELIVERY

Topical drug delivery is the process of delivering drugs into the skin
(dermal delivery) so that they can be effective in the treatment of
dermatological or localized conditions and diseases, or through the skin
(transdermal delivery) and into the bloodstream for the treatment of systemic
diseases.

3

The skin is made up of three layers: the outer layer or stratum corneum;
the middle layer or viable epidermis; and the inner layer or dermis. The stratum
corneum, which serves as the skin's primary barrier to the external environment,
consists of closely packed dead cells and fatty (lipid) material. The epidermis
is composed of several layers of active cells and the dermis consists, in part,
of tissue containing hair follicles, nerve endings and blood capillaries. Within
the stratum corneum, lipid layers bind the dead cells together to form a
protective barrier. Research conducted by MacroChem shows that SEPA compounds
affect drug delivery by acting, in part, upon the stratum corneum to disrupt the
alignment of the lipid molecules within the lipid layers. This disruption
increases the porosity of the lipid-cell layers, allowing drugs to diffuse
through the stratum corneum through the more porous epidermis to the dermis,
where they enter the blood stream through the capillaries. The rate and amount
of drug absorbed can be controlled by varying the formulation used.

MACROCHEM'S DRUG DELIVERY SYSTEMS AND OTHER PROPOSED PRODUCTS

SEPA COMPOUNDS

The delivery of a drug through the skin depends on the drug's physical and
chemical characteristics (molecular size and shape, the drug's solubility in
lipids and water, its melting point and whether it is lipophilic or
hydrophilic).

Since some drugs move through the skin too rapidly, the transdermal system
must retard the rate of drug absorption to ensure optimal efficacy with minimum
toxicity. Since other drugs move through the skin with difficulty, the
transdermal system must be formulated to increase a drug's rate of absorption
through the skin. Common methods of transdermal delivery use common chemicals
such as ethanol or fatty compounds to enhance penetration.

Although certain delivery methods using chemicals have proven to be
somewhat effective with specific drugs, such as drugs used for the treatment of
motion sickness or hormone deficiencies, they have caused adverse events, such
as skin irritation and sensitivity at the site of application. Some drugs,
because of their physical characteristics or the amount of drug necessary to
achieve the desired therapeutic effect, have not been successfully delivered
transdermally to date.

MacroChem has developed SEPA compounds that are designed to enhance the
transport, penetration and controlled delivery of drugs through the skin. SEPA
compounds are generally colorless, clear liquids that are intended to promote
drug delivery by aiding drug molecules to penetrate the skin, diffuse into or
through the skin layers and become absorbed into the bloodstream.

We have our own facility for the in vitro testing of drug formulations
containing SEPA, and therefore are less dependent on outside laboratories for
this type of testing. We are conducting in vitro studies to evaluate the
transdermal enhancing effect of SEPA in combination with a variety of drugs with
differing physical and chemical characteristics, representing a broad spectrum
of potential drug products. Although our research and development efforts with
SEPA are at an advanced stage, we must still conduct substantial additional
studies to demonstrate the efficacy and safety of any SEPA-drug formulation. We
have found that specific drugs administered transdermally with SEPA demonstrate


4


increased transdermal absorption. Some of the drug formulations tested by us
with SEPA contain compounds generally recognized as unlikely or difficult
candidates for transdermal delivery because of their physical and chemical
properties and molecular size. As these drug formulations are further developed,
we plan to conduct additional studies to investigate the efficacy and safety of
some of these formulations.

We have conducted early clinical studies with several drug formulations
containing SEPA where SEPA has been demonstrated to enhance transdermal
penetration of the specific drug within in vitro testing. Clinical studies have
included Phase I trials in which safety and tolerance of a topical application
of the drug formulation were assessed and Phase II trials in which efficacy of
the specific drug was evaluated in an appropriate clinical condition.

We have designed and sponsored clinical trials of Topiglan(R), our topical
formulation of alprostadil and SEPA for use in the treatment of erectile
dysfunction. A Phase III trial of Topiglan demonstrated improvement in total
erectile function score and improvement of the International Index of Erectile
Function domain score among protocol-conforming patients treated with Topiglan
versus a control vehicle. The Company has designed and sponsored in vitro and
clinical studies of its topical formulation of SEPA and testosterone for use in
treating male hypogonadism. These studies demonstrated that SEPA enhanced
penetration of testosterone through the skin.

The Company has also conducted pre-clinical laboratory studies with SEPA
formulations of nonsteroidal anti-inflammatory drugs for topical application in
pain management.

In addition to the ongoing clinical development programs cited above,
MacroChem has conducted a pre-clinical study of EcoNail (TM), its formulation of
SEPA in combination with active antifungal agents to treat fungal infections of
the nail. The study demonstrated substantially increased nail penetration by an
antifungal drug when combined with SEPA.

We believe that SEPA compounds can be used with a broad variety of new and
existing drugs to enhance their commercial value. The therapeutic effectiveness
and improved convenience of a transdermal SEPA product may substantially expand
the existing market for a drug. In addition, a formulation containing a SEPA
compound may prove to be a superior alternative to the existing methods of
administering certain drugs.

MACRODERM(TM) DRUG DELIVERY SYSTEM

We have developed a series of new low molecular weight polymers, termed
MacroDerm, for use in cosmetics and in the superficial dermal delivery of
pharmaceuticals. Potential applications include their use with sunscreens,
moisturizers, and insect repellents. We have synthesized, tested and evaluated
MacroDerm prototypes and are seeking strategic partners to manufacture and
market specific MacroDerm products.

COMPETITION

We compete with numerous firms, many of which are large, multi-national
organizations with worldwide distribution. We believe that our major competitors


5


in the drug delivery sector of the health care industry include NexMed, Inc.,
Bentley Pharmaceuticals, Inc., ALZA Corporation, Cygnus Therapeutic Systems,
Elan Corporation, plc., Novartis and Pfizer. Compared with MacroChem, most of
these firms have substantially greater capital resources, research and
development and technical staffs, facilities and experience in obtaining
regulatory approvals, as well as in manufacturing, marketing and distribution of
products. Recent trends in this area are toward further market consolidation of
large drug companies into a smaller number of very large entities, further
concentrating financial, technical and market strength and increasing
competitive pressure in the industry. Academic institutions, hospitals,
governmental agencies and other public and private research organizations are
also conducting research and seeking patent protection and may develop competing
products or technologies of their own through joint ventures or other
arrangements. In addition, recently developed technologies or technologies that
may be developed in the future may or could be the basis for competitive
products. We cannot guarantee that our competitors will not succeed in
developing technologies and products that are more effective or less costly to
use than any that we are currently developing.

Alprostadil, a synthetic prostaglandin E1 (PGE1), and Viagra(R) are the
only drugs approved for marketing in the United States for erectile dysfunction.
PGE1 is available in two dosage forms. Caverject(R), marketed by Pharmacia &
Upjohn, is administered by needle injection directly into the penis. The second
product, developed by Vivus, is a pellet form of the drug administered through a
tube inserted into the urethra. In contrast to the invasive forms now available,
MacroChem believes that a topical gel formulation applied to the penis will be
the preferred dosage form for treatment of this disorder. Viagra(R), an oral
product of Pfizer, was approved by the FDA in 1998. Many large drug companies
have announced internal programs to develop orally administered alternatives to
Pfizer's Viagra for treating male erectile dysfunction. In addition, NexMed,
Inc. has announced commencement of U.S. Phase III clinical trials of its topical
cream formulation of alprostadil for treating the disease.

With respect to EcoNail, Johnson & Johnson and Novartis each offer an
orally administered anti-fungal therapy and Dermik Laboratories offers a topical
nail lacquer therapy for treating fungal infections of the nail. A number of
smaller firms are also developing topical and oral therapies for these
infections.

We expect any products approved for sale to compete primarily on the basis
of efficacy, safety, patient compliance, reliability, price and patent position.
Generally, the first pharmaceutical product to reach the market in a therapeutic
or preventive area often has a significant advantage compared with later
entrants to the market. Our competitive position will also depend on our ability
to attract and retain qualified scientific and other personnel, develop
effective proprietary products, implement production and marketing plans, obtain
patent protection and secure adequate capital resources.

EMPLOYEES

As of March 1, 2002, the Company had 32 full time employees, 21 of whom are
devoted to research and development and regulatory affairs. None of our
employees are covered by a collective bargaining agreement, and we consider
relations with our employees to be good.

GOVERNMENT REGULATION

The production and marketing of our drug delivery systems and
pharmaceutical products are subject to regulation for safety, efficacy and
quality by numerous federal, state and local agencies and comparable agencies in
foreign countries. In the United States, the Federal Food, Drug and Cosmetics
Act, the Public Health Service Act, the Controlled Substances Act and other
federal statutes and regulations govern or influence the testing, manufacture,
safety, labeling, storage, record keeping, approval, advertising and promotion
of our proposed products and technologies.

Non-compliance with applicable requirements can result in fines and other
judicially imposed sanctions including recalls and criminal prosecutions based
on violation of statutory requirements by products, promotional practices, or
manufacturing practices. In addition, administrative remedies can involve
voluntary recalls or cessation of sale of products, administrative detention,
public notice, voluntary changes in labeling, manufacturing or promotional
practices, as well as refusal of the government to approve New Drug Applications
(NDAs). The FDA also has the authority to withdraw approval of drugs in
accordance with statutory procedures.

The FDA approval procedure involves completion of certain pre-clinical and
manufacturing/stability studies and the submission of the results of these
studies to the FDA in an Investigational New Drug (IND) application in support
of performing clinical trials. IND allowance is then followed by performance of
human clinical trials, and additional pre-clinical and manufacturing quality
control studies, supporting safety, efficacy and manufacturing quality control.
The safety, chemistry, manufacturing and stability and clinical studies
developed under the IND are compiled into an NDA or Abbreviated New Drug
Application (ANDA) and submitted to the FDA for approval to market.

Preclinical studies involve laboratory evaluation of product
characteristics and animal studies to assess the efficacy and safety of the
product. Human clinical trials are typically conducted in three sequential
phases, but the phases may overlap. Phase I trials consist of testing of the
product in a small number of normal volunteers primarily for safety. In Phase
II, in addition to safety, the efficacy of the product is evaluated in a small
patient population. Phase III trials typically involve multicenter testing for
safety and clinical efficacy in an expanded population of patients at
geographically dispersed test sites. A clinical plan, or "protocol," accompanied
by the identification of the institutions participating in the trials, must be
submitted to the FDA prior to commencement of each clinical trial. The FDA may
order the temporary or permanent discontinuation of a clinical trial at any time
if adverse events that endanger patients in the trials are observed. In
addition, the FDA may request Phase IV clinical trials, to be performed after
marketing approval, to resolve any lingering questions.

A 30-day waiting period after the filing of each IND application is
required by the FDA prior to the commencement of clinical testing in human
subjects. If the FDA does not comment on or question the IND application within
30 days, initial clinical studies may begin. However, any FDA comments or
questions must be answered to the satisfaction of the FDA before initial
clinical testing can begin. In some instances, this process could result in
substantial delay and expense.

7


The results of the preclinical and clinical studies on new drugs are
submitted to the FDA in the form of NDAs for approval to commence commercial
sales. Following extensive review, the FDA may grant marketing approval, require
additional testing or information, or deny the application. All products must
continue to comply with all FDA requirements and the conditions in an approved
application, including product specifications, manufacturing process and
labeling requirements. Failure to comply, or the occurrence of unanticipated
adverse events during commercial marketing, could lead to the need for labeling
changes, product recall, seizure, injunctions against distribution or other
FDA-initiated action, which could delay further marketing until the products are
brought into compliance.

In certain cases, an ANDA may be filed in lieu of filing an NDA. An ANDA
relies on bioequivalency tests that compare the applicant's drug with an already
approved reference drug, rather than on clinical trials. An ANDA may be
available to us for a new formulation of a drug which has already been approved
by the FDA in other topical dosage forms.

The NDA itself is a complicated and detailed document and must include the
results of extensive animal, clinical and other testing, the cost of which is
substantial. Although the FDA is required to review applications within 180 days
of filing, in the process of reviewing applications the FDA frequently requests
that additional information be submitted and restarts the 180-day regulatory
review period when the requested additional information is submitted. The effect
of such requests and subsequent submissions can significantly extend the time
for the NDA review process. Until an NDA is actually approved, no assurance can
be given that the information requested and submitted will be considered
adequate by the FDA to justify approval.

In addition, packaging and labeling of most of our proposed products are
subject to FDA regulation. We must get FDA approval for all labeling and
packaging prior to marketing of a regulated product.

Whether or not FDA approval has been obtained, approval of a product by a
comparable regulatory authority must be obtained in most foreign countries
before marketing of the product in that country. The approval procedure varies
from country to country and may involve additional testing, and the time
required may differ from that required for FDA approval. Although some
procedures for unified filings exist for certain European countries, in general
each country has its own procedure and requirements, many of which are time
consuming and expensive. Thus, substantial delays in obtaining required
approvals from foreign regulatory authorities can result after the relevant
applications are filed. After such approvals are obtained, further delays may be
encountered before the products become commercially available.

We cannot guarantee that any required FDA or other governmental approval
will be granted or, if granted, will not be withdrawn. Governmental regulation
may prevent or substantially delay the marketing of our proposed products, cause
us to undertake costly procedures and furnish a competitive advantage to the
more substantially capitalized companies with which we plan to compete. In
addition, we cannot predict the extent of potentially adverse government
regulations that may arise from future administrative action or legislation.

PATENTS, TRADEMARKS AND LICENSE RIGHTS

During 2001, one new U.S patent was issued to the Company (No. 6,224,887),
directed to EcoNail(TM), the Company's antifungal nail lacquer. A foreign patent
was granted in Europe for the composition and method for treating penile
erectile dysfunction (Topiglan(R) product). In addition, a European application
was allowed for a once per day Minoxidil composition - a method for treating
hair loss.

During the year we filed two new U.S. patent applications. One application
is for the composition and method for topical administration of methimazole in
the treatment of hyperthyroidism in cats and the other is directed to ibuprofen
salt emulsifiers and cream formulations containing the same.

We believe that patent protection of our technologies, processes and
products is important to our future operations. The success of our proposed
products may depend, in part, upon our ability to obtain patent protection.

Although we intend to file additional patent applications, as management
believes appropriate for any new products or technological developments, we
cannot guarantee that any additional patents will be issued or, if issued, will
be of commercial benefit to us. In addition, to anticipate the breadth or degree
of protection that any such patents may afford is impossible. To the extent that
we rely on unpatented proprietary technology, we cannot guarantee that others
will not independently develop or obtain substantially equivalent or superior
technology or otherwise gain access to our trade secrets, that any obligation of
confidentiality will be honored or that we will be able to effectively protect
our rights to proprietary technology. Further, we cannot guarantee that any
products developed by us will not infringe patents held by third parties or
that, in such case, licenses from such third parties will be available on
commercially acceptable terms, if at all.

In connection with our prior research and development efforts, we own
several patents and possess certain license rights in connection with other
technologies, which we are not currently pursuing. We intend to enforce our
patent position and intellectual property rights vigorously. The cost of
enforcing our patent rights in lawsuits, if necessary, may be significant and
could interfere with our operations.

RISK FACTORS

In addition to the other information in this report, the following risk
factors should be considered carefully in evaluating us and our business. This
report contains forward-looking statements that involve risks and uncertainties.
Our actual results may differ significantly from the results discussed in the
forward-looking statements in this report and in forward-looking statements made
from time to time by the us on the basis of management's then-current
expectations. Factors that might cause such a difference include, but are not
limited to, those discussed or referred to below.

9


WE HAVE A HISTORY OF OPERATING LOSSES AND WILL CONTINUE TO NEED WORKING CAPITAL.

Since 1981, we have been engaged primarily in research and development and
have derived limited revenues from feasibility studies, the commercial sale of
our products and the licensing of certain technology. We have not generated any
revenues from the sale of any products currently under development. We have
incurred net losses every year since we began doing business and we anticipate
that losses will continue for the foreseeable future. As of December 31, 2001,
we had an accumulated deficit of $55,374,000. Our ability to continue operations
after our current capital resources are exhausted depends on our ability to
secure additional financing and to become profitable, which we cannot guarantee.

We continue to pursue the commercialization of our SEPA technology through
discussions with potential licensees. There can be no guarantee that these
discussions will lead to any licenses or that we will receive any license fees.
Until marketing approvals are obtained and/or license agreements are entered
into, if ever, we expect to generate only limited licensing revenue and no
royalties from sales of products using SEPA. In addition, we intend to continue
to make the substantial expenditures required to support our research and
development programs, including preclinical studies and clinical trials. As a
result, we expect to incur operating losses for the foreseeable future.

OUR PRODUCTS ARE IN AN EARLY STAGE OF DEVELOPMENT AND REMAIN SUBJECT TO
TECHNOLOGY UNCERTAINTY.

Various pharmaceutical companies have developed systems to enhance the
transdermal delivery of specific drugs, but relatively limited research has been
conducted about using transdermal delivery systems for a wider range of
pharmaceutical products. Although we have demonstrated in preclinical and
clinical studies that SEPA transdermal compounds may have applicability when
paired with a broad range of drugs, transdermal delivery systems are currently
marketed for only a limited number of products. In addition, some transdermal
delivery systems used to date have demonstrated adverse side effects for users,
including skin irritation and delivery difficulties.

Most of our proposed products are in the early development stage and will
require significant further research, development, testing and regulatory
clearances. Our proposed products are subject to the risks of failure inherent
in the development of products based on innovative technologies. These risks
include the possibilities that any or all of the proposed products may be found
to be ineffective or toxic, or otherwise may fail to receive necessary
regulatory clearances. In addition, even if our proposed products are effective,
they may be uneconomical to market or third parties may market superior or
equivalent products. Due to the extended testing and regulatory review process
required before we obtain marketing clearance for any of our proposed products,
we do not expect to realize royalty revenues from the sale of any drugs in the
foreseeable future.

10



WE WILL NEED TO MAKE SIGNIFICANT PRODUCT DEVELOPMENT EFFORTS AND RECEIVE
ADDITIONAL FINANCING TO MARKET OR LICENSE ANY PRODUCTS.

Before we or any of our potential licensees may market any products based
upon our technology, significant additional development efforts and substantial
testing will be necessary. In most cases, we will require substantial additional
financing to fund clinical studies on our proposed products. We cannot guarantee
that we will be able to secure such financing on favorable terms, if at all.

OUR PRODUCTS MAY NOT SUCCESSFULLY COMPLETE THE EXTENSIVE REGULATORY APPROVAL
PROCESS REQUIRED PRIOR TO ANY PHARMACEUTICAL PRODUCT BEING MARKETED.

Before obtaining regulatory approval for the commercial sale of any of the
pharmaceutical products we have under development, we must demonstrate that the
product is safe and efficacious for use in each proposed indication. The results
of preclinical studies and early clinical trials may not accurately predict
results that will be obtained in large-scale testing, and we cannot guarantee
that clinical trials will prove that our products are safe and efficacious or
that any of our products will ultimately be marketable. A number of other
companies in the pharmaceutical industry have suffered significant setbacks in
advanced clinical trials, even after they achieved promising results in earlier
trials. If we are unable to demonstrate the safety and efficacy of our products,
we may be adversely affected.

WE DEPEND ON THIRD PARTIES ENTERING INTO LICENSE ARRANGEMENTS WITH US AND
HELPING US DEVELOP OUR PRODUCTS.

To the extent we rely on licensees and joint venture arrangements to fund
most of the costs relating to product development and clinical trials, licensees
may have the legal right to terminate funding for a product at any time for any
reason without significant penalty. We cannot control the resources and
attention that a licensee may devote to a product and this can result in delays
in clinical testing, regulatory filings and commercialization efforts. We also
cannot guarantee that we will be able to enter into collaborative arrangements
or that any collaborative arrangements will succeed.

OUR PRIOR DEVELOPMENT EFFORTS HAVE NOT GENERATED SUSTAINED REVENUES OR ANY
PROFITS.

Since 1981, we have engaged in research and development activities with
respect to a variety of technologies and products, including polymers for
medical and industrial use, dental adhesives, osteoporotic drugs and transdermal
drug delivery products. None of our products or technologies has ever generated
sustained revenues and we have never been profitable. We have expended
substantial resources in researching and developing technology relating to our
products as well as in connection with the research and development of
transdermal delivery systems. We cannot guarantee that our development
activities with respect to transdermal delivery systems will be successful or
that these efforts will not eventually be abandoned.

11



WE LACK MARKETING EXPERIENCE AND AS A RESULT WE DEPEND ON THIRD PARTIES TO
MARKET AND DISTRIBUTE OUR PRODUCTS.

We intend to market and distribute our proposed products through other
companies. We cannot guarantee that we will be able to enter into agreements
with other companies on acceptable terms, if at all. We may have to cede control
over some or all aspects of the marketing and sales of our products as a
condition to entering into such arrangements. We currently have no sales force
or marketing organization. If we decide to directly market and sell any of our
products, we will, among other things, have to develop such capabilities,
including the ability to attract and retain qualified and experienced marketing
and sales personnel. We cannot guarantee that we will be able to attract and
retain qualified and experienced marketing and sales personnel or that any
efforts undertaken by such personnel will be successful.

WE DEPEND ON THIRD PARTIES TO MANUFACTURE OUR PRODUCTS.

We do not have facilities capable of manufacturing any of our proposed
products in commercial quantities and we do not have plans to obtain such
facilities. Accordingly, we will depend to a significant extent on licensees or
corporate partners for such manufacturing and for compliance with regulatory
requirements for good manufacturing practices. There can be no guarantee that
such partners or licensees will perform their obligations in a timely fashion.
Our dependence on third parties for manufacturing may adversely affect our
ability to develop and deliver products on a timely and competitive basis. If we
decide to establish a commercial manufacturing facility, we will require
substantial additional funds. We will be required to hire and retain significant
additional personnel and we will have to comply with extensive government
regulations. We cannot guarantee that we will be able to obtain the additional
capital required to conduct manufacturing activities directly on acceptable
terms, if at all.

OUR BUSINESS WILL SUFFER IF WE LOSE KEY PERSONNEL.

The success of our business depends on our ability to attract, retain and
motivate qualified senior management personnel who are in high demand.

OUR BUSINESS WILL SUFFER IF WE FAIL TO ATTRACT AND RETAIN EXPERIENCED SCIENTIFIC
PERSONNEL.

Our business also depends on our ability to attract and retain scientific
personnel. The competition for such experienced personnel is intense and can be
expected to increase. We cannot guarantee that we will be able to retain our
existing personnel or attract additional qualified employees.

OUR INDUSTRY IS HIGHLY COMPETITIVE AND MANY OF OUR COMPETITORS HAVE
SIGNIFICANTLY MORE RESOURCES THAN WE HAVE.

We compete with numerous firms, many of which are large, multi-national
organizations with worldwide distribution. We believe that our major competitors
in the drug delivery sector of the health care industry include NexMed, Inc.,
Bentley Pharmaceuticals, Inc., ALZA Corporation, Cygnus Therapeutic Systems,
Elan Corporation, plc., Novartis and Pfizer. Compared with MacroChem, most of


12


these firms have substantially greater capital resources, research and
development and technical staffs, facilities and experience in obtaining
regulatory approvals, as well as in manufacturing, marketing and distribution of
products. Recent trends in this area are toward further market consolidation of
large drug companies into a smaller number of very large entities, further
concentrating financial, technical and market strength and increasing
competitive pressure in the industry. Academic institutions, hospitals,
governmental agencies and other public and private research organizations are
also conducting research and seeking patent protection and may develop competing
products or technologies of their own through joint ventures or other
arrangements. In addition, recently developed technologies or technologies that
may be developed in the future may or could be the basis for competitive
products. We cannot guarantee that our competitors will not succeed in
developing technologies and products that are more effective or less costly to
use than any that we are currently developing.

We expect any products approved for sale to compete primarily on the basis
of efficacy, safety, patient compliance, reliability, price and patent position.
Generally, the first pharmaceutical product to reach the market in a therapeutic
or preventive area often has a significant advantage compared with later
entrants to the market. Our competitive position will also depend on our ability
to attract and retain qualified scientific and other personnel, develop
effective proprietary products, implement production and marketing plans, obtain
patent protection and secure adequate capital resources.

OUR PRODUCTS ARE SUBJECT TO RIGOROUS GOVERNMENTAL REVIEW AND SIGNIFICANT
REGULATION.

Our technologies must undergo a rigorous regulatory approval process, which
includes extensive preclinical and clinical testing, to demonstrate safety and
efficacy before any resulting product can be marketed. To date, neither the FDA
nor any of its international equivalents has approved any of our technologies
for marketing. The clinical trial and regulatory approval process can require
many years and substantial cost, and there can be no guarantee that our efforts
will result in an approved product.

Our activities are regulated by a number of government authorities in the
United States and other countries, including the FDA. The FDA regulates
pharmaceutical products, including their manufacture and labeling. Data obtained
from testing is subject to varying interpretations which can delay, limit or
prevent FDA approval. Risks associated with the regulatory approval process
include:

o Changes in existing regulatory requirements could prevent or affect our
regulatory compliance. Federal and state laws, regulations and policies may
be changed with possible retroactive effect, and how these rules actually
operate can depend heavily on administrative policies and interpretations
over which we have no control or inadequate experience to assess their full
impact upon our business.

o Obtaining FDA clearances is time-consuming and expensive and we cannot
guarantee that such clearances will be granted or, if granted, will not be
withdrawn.

13


o The FDA review process may prevent the marketing of our products or may
involve delays that significantly and negatively affect our products. We
may encounter similar delays in foreign countries.

o Regulatory clearances may place significant limitations on the uses for
which any approved products may be marketed.

o Any marketed product and its manufacturer are subject to periodic review.
Any discovery of previously unrecognized problems with a product or
manufacturer could result in suspension or limitation of approvals.

WE DEPEND ON PATENTS TO PROTECT OUR TECHNOLOGIES AND THE SCOPE OF SUCH
PROTECTION IS INHERENTLY UNCERTAIN.

We believe that patent protection of our technologies, processes and
products is important to our future operations. The success of our proposed
products may depend, in part, upon our ability to obtain patent protection.

Although we intend to file additional patent applications, we cannot
guarantee that any additional patents will be issued or, if issued, will be of
commercial benefit to us. In addition, it is impossible to anticipate the
breadth or degree of protection that any such patents may afford. There can be
no guarantee that other parties will not commence litigation challenging our
existing or future patents or that we will be successful in defending against
any such challenge. To the extent that we rely on unpatented proprietary
technology, we cannot guarantee that others will not independently develop or
obtain substantially equivalent or superior technology or otherwise gain access
to our trade secrets, that any obligation of confidentiality will be honored or
that we will be able to effectively protect our rights to proprietary
technology. Further, products we develop could infringe patents held by third
parties. In such cases, licenses from the third parties may not be available on
commercially acceptable terms, if at all.

We intend to enforce our patent position and intellectual property rights
vigorously. The cost of enforcing our patent rights in lawsuits, if necessary,
may be significant and could interfere with our operations.

WE FACE THE RISK OF PRODUCT LIABILITY CLAIMS AND WE MAY NOT HAVE SUFFICIENT
PRODUCT LIABILITY INSURANCE TO COVER SUCH CLAIMS. IT MAY BE EXPENSIVE AND
DIFFICULT TO OBTAIN ADEQUATE INSURANCE COVERAGE.

The design, development, manufacture and sale of our products involve risk
of liability claims and associated adverse publicity. We currently have
liability insurance to cover claims related to our products that may arise from
clinical trials, but we do not maintain product liability insurance and we may
need to acquire such insurance coverage prior to the commercial introduction of
our products. Such insurance is expensive, may be difficult to obtain and may
not be available on acceptable terms, if at all. If we obtain such coverage, we
have no guarantee that the coverage limits of such insurance policies will be
adequate. A successful claim against us if we are uninsured, or which is in
excess of our insurance coverage, if any, could have a material adverse effect
upon us and our financial condition.

14


GOVERNMENT OR PRIVATE INITIATIVES TO REDUCE HEALTH CARE COSTS COULD HAVE A
MATERIAL ADVERSE EFFECT ON PHARMACEUTICAL PRICING AND ON US.

The future revenues and profitability of, and availability of capital for,
biomedical and pharmaceutical companies such as us may be affected by the
continuing efforts of governmental and third-party payers to contain or reduce
the costs of health care through various means. For example, in certain foreign
markets pricing or profitability of prescription pharmaceuticals is subject to
government control and to reform in the health care system. In the United
States, there have been, and we expect there will continue to be, a number of
federal and state proposals to impose similar government control. While we
cannot predict whether any such legislative or regulatory proposals will be
adopted, the announcement or adoption of such proposals could have a material
adverse effect on our prospects. If we or one of our partners succeeds in
bringing to market one or more of our products, there can be no assurance that
these products will be cost effective and that reimbursement to the consumer
will be available or will be sufficient to allow us or our partners to sell such
products on a profitable basis.

ITEM 2. PROPERTIES.

We occupy 17,277 square feet of office and laboratory space under a lease
expiring February 28, 2005. This space is located on one floor of a three story
building in Lexington, Massachusetts. We believe that this facility is adequate
to meet our current and foreseeable future requirements.

ITEM 3. LEGAL PROCEEDINGS.

None.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

There were no matters submitted to a vote of stockholders during the three
months ended December 31, 2001, through the solicitation of proxies or
otherwise.

RECENT SALES OF UNREGISTERED SECURITIES

During 2001, we issued the following securities that were not registered
under the Securities Act of 1933 at the time they were issued:

o In July 2001, we issued 1,566,047 shares of our Common Stock for
$10,148,000 in gross proceeds ($9,406,000 net of issuance costs) to
institutional investors. The investors also received warrants to purchase
an aggregate of 313,209 shares of Common Stock at a purchase price of
$8.995 per share expiring five years from the closing date. The warrants
are callable by the Company if the closing price of the stock is higher
than $17.99 for 15 consecutive trading days at any time before expiration.
As of December 31, 2001, none of these warrants had been exercised.

16


The transactions described above were effected in reliance upon the
exemption from the registration requirements of the Securities Act of 1933
provided by Section 4(2) on the basis that such transactions did not involve any
public offering.

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

The following discussion of the financial condition and results of
operations for the Company should be read in conjunction with the accompanying
financial statements and related footnotes.

GENERAL

MacroChem's primary business is the development of pharmaceutical products
for commercialization by employing SEPA(R) (Soft Enhancer of Percutaneous
Absorption), its patented drug delivery technology. SEPA compounds, when
properly combined with drugs, provide pharmaceutical formulations (creams, gels,
lacquers, solutions, etc.) that enhance the transdermal delivery of drugs into
the skin or into the bloodstream. The Company currently derives no significant
revenue from product sales, royalties or license fees. The Company plans to
develop specific SEPA formulations for use with proprietary and non-proprietary
drugs manufactured by pharmaceutical companies, and to commercialize these
products through the formation of partnerships, strategic alliances and
licensing arrangements with those companies. In order to attract strategic
partners the Company is conducting clinical testing of certain SEPA-enhanced
drugs.

17


The Company's results of operations can vary significantly from year to
year and quarter to quarter, and depend, among other factors, on the signing of
new licenses and product development agreements, the timing of revenues
recognized pursuant to license agreements, the achievement of milestones by
licensees, the progress of clinical trials conducted by licensees and the
Company, and the degree of research, marketing and administrative effort. The
timing of the Company's revenues may not match the timing of the Company's
associated product development expenses. To date, research and development
expenses have generally exceeded revenues in any particular period and/or fiscal
year.

CRITICAL ACCOUNTING POLICIES

Note 1 of the consolidated financial statements, included elsewhere in this
Form 10-K, includes a summary of the significant accounting policies and methods
used in the preparation of our consolidated financial statements. The following
is a brief discussion of the more significant accounting policies and methods
used by us.

The Company's discussion and analysis of its financial condition and
results of operations are based upon our financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States of America. The preparation of these financial statements requires
the Company to make estimates and judgments that affect the reported amounts of
assets, liabilities, revenues and expenses.

The Company believes the following critical accounting policies affect its
more significant judgments and estimates used in the preparation of its
financial statements. As more fully described in the notes to the financial
statements, we derive revenue from research and co-development programs.
Research and co-development revenue is billed on a cost reimbursement basis,
which includes direct costs incurred in connection with research activities and
an allocation of certain other costs incurred by the Company. Research and
development costs are charged to operations as incurred. Costs and expenses
incurred in connection with pending patent applications are deferred. Costs
related to successful patent applications are amortized over the estimated
useful lives of the patents using the straight-line method. Accumulated costs
related to patents or deferred patent application costs that are considered to
have limited future value are charged to operations.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 2001 COMPARED TO THE YEAR ENDED DECEMBER 31, 2000

For 2001 and 2000, the Company recognized revenues of approximately
$829,400 and $629,600, respectively. Also during 2001, we obtained a small
business grant of $158,500 funded by the Department of Health and Human
Services. The year 2000 revenue includes $500,000 in deferred revenue which was
recognized from the termination of a collaboration agreement.

18


Research and development costs increased by approximately $4,510,000 from
approximately $5,281,000 in 2000 to approximately $9,791,000 in 2001, an 85%
increase. This change for the period is primarily attributable to an increase in
clinical trial expenses due to a Topiglan Phase III study and an increase in R&D
salaries. Of total R&D expenses, approximately $363,500 in 2001 and $253,600 in
2000 were paid to independent third party contractors. The Company expects that
research and development expenses will increase by approximately 20% for 2002 as
compared to 2001.

Marketing, general and administrative expenses for 2001 aggregated
approximately $4,000,000, a decrease of approximately $1,794,000 or 31%, from
2000's total of approximately $5,794,000. This decrease is primarily the result
of a $2,809,000 stock-based compensation charge related to the extension of
certain stock options to key employees in the second quarter of 2000, offset by
an increase in general and administrative salaries, travel and other related
expenses in 2001. The Company expects that marketing, general and administrative
expenses will remain essentially the same as 2001 for 2002 with the exception of
routine salary increases and any stock-based compensation charges.

Total other income decreased by approximately $61,000 or 8%, from $752,000
in 2000 to $691,000 in 2001. The decrease is attributable primarily to lower
interest income as a result of lower interest rates.

For the year ended December 31, 2001, our net loss was approximately
$12,333,000 as compared to a loss of approximately $9,745,000 for the previous
year, a 27% increase.

YEAR ENDED DECEMBER 31, 2000 COMPARED TO THE YEAR ENDED DECEMBER 31, 1999

For 2000 and 1999, the Company recognized revenues of approximately
$629,600 and $464,300, respectively. Although there was a drop in feasibility
studies in 2000, $500,000 in deferred revenue was recognized in 2000 from the
termination of a collaboration agreement.

Research and development costs decreased by approximately $142,000 from
approximately $5,423,000 in 1999 to approximately $5,281,000 in 2000, a 3%
decrease. This decrease was primarily attributable to a $255,000 stock
compensation adjustment, which was partially offset by a slight increase in
clinical trial expenses from Phase II to Phase III for Topiglan.

Marketing, general and administrative expenses for 2000 aggregated
approximately $5,794,000, an increase of approximately $3,183,000, or 122%, from
1999's total of approximately $2,611,000. This increase was primarily the result
of $2,809,000 in stock-based compensation related to the extension of certain
stock options to key employees in the second quarter of 2000.

Other income decreased by approximately $79,000, or 10%, from $831,000 in
1999 to $752,000 in 2000. The decrease was attributable primarily to assets
being held as short-term marketable securities and a softening of the interest
rates.

19


For the year ended December 31, 2000, our net loss was approximately
$9,745,000 as compared to a loss of approximately $6,787,000 for the previous
year, a 44% increase.

LIQUIDITY AND CAPITAL RESOURCES

Since inception, the primary source of funding for the Company's operations
has been the private and public sale of its securities, and to a lesser extent,
the licensing of its proprietary technology and products, research
collaborations, feasibility studies, government grants and the limited sales of
products and test materials. During 2001, the Company received aggregate net
proceeds of approximately $11,785,000 from the exercise of stock options and
warrants and sale of common stock, compared to approximately $8,886,000 in 2000.
At December 31, 2001, working capital was approximately $15.7 million, compared
to $16.0 million at December 31, 2000. The decrease in the Company's working
capital was due principally to the increase in accrued research expenses and
employment contracts and other miscellaneous accounts payable accrued at
December 31, 2001. Until such time as the Company obtains agreements with
third-party licensees or partners to provide funding for the Company's
anticipated business activities, the Company's working capital will be utilized
to fund its operating activities.

Pursuant to a plan approved by the Company's Board of Directors, the
Company is authorized to repurchase 1,000,000 shares of its common stock to be
held as treasury shares for future use. During 2001, the Company did not
repurchase any shares of Common Stock. At December 31, 2001, 253,346 repurchased
shares remain available for future use and 679,587 shares remain available for
repurchase under the plan.

Capital expenditures and additional patent development costs for the year
ended December 31, 2001 were approximately $420,700. The Company anticipates
capital expenditures of approximately $370,000 during the fiscal year ending
December 31, 2002.

In July 2001, the Company sold 1,566,047 shares of its common stock for
$10,148,000 in gross proceeds ($9,406,000 net of issuance costs) in a private
placement to institutional investors.

The investors also received warrants to purchase an aggregate of 313,209
shares of common stock at a purchase price of $8.995 per share expiring in five
years from the closing date. The warrants are callable by the Company if the
closing price of the stock is higher than $17.99 for 15 consecutive trading days
at any time before expiration. As of December 31, 2001, none of the $8.995
warrants had been exercised.

The Company believes that its existing cash and cash equivalents will be
sufficient to meet its operating expenses and capital expenditure requirements
for at least the next twelve months. The Company's cash requirements may vary
materially from those now planned because of changes in focus and direction of
the Company's research and development programs, competitive and technical
advances, patent developments or other developments. The Company will require
additional financing to continue its long term plans for clinical trials and new
product development. Funding will be secured through a private placement or
possible secondary public offering depending on certain events. It is not
believed that inflation will have any significant effect on the results of the
Company's operations.

RECENT ACCOUNTING PRONOUNCEMENTS

In 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"). SFAS No. 133 establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. The adoption of SFAS No. 133 on
January 1, 2001 had no impact on the Company's financial statements.

In June 2001, the FASB issued two new pronouncements: SFAS No. 141,
Business Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets.
SFAS No. 141 is effective as follows: a) use of the pooling-of-interest method
is prohibited for business combinations initiated after June 30, 2001; and b)
the provisions of SFAS No. 141 also apply to all business combinations accounted
for by the purchase method that are completed after June 30, 2001 (that is, the
date of acquisition is July 2001 or later). SFAS No. 142 is effective for fiscal
years beginning after December 15, 2001 to all goodwill and other intangible
assets recognized in an entity's statement of financial position at that date,
regardless of when those assets were initially recognized. SFAS No. 142 requires
that upon adoption, amortization of goodwill and other intangible assets with
indefinite useful lives will cease and instead, the carrying value of these
assets will be evaluated for impairment on an annual basis. On January 1, 2002,
the Company adopted these statements which will have no effect on the Company's
financial position or results of operations.

In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets" ("SFAS No. 144"), which addresses
financial accounting and reporting for the impairment or disposal of long-lived
assets. This Statement supercedes SFAS No. 121, and the accounting and reporting
provisions of APB 30, for the disposal of a segment of a business. The
provisions of SFAS No. 144 are required to be adopted by the Company effective
January 1, 2002. On January 1, 2002, the Company adopted this statement, which
will have no effect on the Company's financial position or results of
operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

As of December 31, 2001, the Company is exposed to market risks which
relate primarily to changes in U.S. interest rates. The Company's cash
equivalents and short-term investments are subject to interest rate risk and
will decline in value if interest rates increase. Due to the short duration of
these financial instruments, generally one year or less, changes to interest
rates would not have a material effect upon the Company's financial position. A
hypothetical 10% change in interest rates would not have a material effect on
our Statement of Operations or Cash Flows for the twelve months ending December
31, 2002 based on December 31, 2001 balances.

THE FOREGOING STATEMENTS IN THIS REPORT INCLUDE FORWARD-LOOKING STATEMENTS
THAT INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS MAY DIFFER
SIGNIFICANTLY FROM THE RESULTS DISCUSSED IN THE FORWARD-LOOKING STATEMENTS.
FACTORS THAT MIGHT CAUSE SUCH A DIFFERENCE INCLUDE, BUT ARE NOT LIMITED TO,
THOSE DISCUSSED OR REFERRED TO IN ITEM 1, BUSINESS - "RISK FACTORS".

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Stockholders of MacroChem Corporation:

We have audited the accompanying balance sheets of MacroChem Corporation as of
December 31, 2001 and 2000, and the related statements of operations,
stockholders' equity, and cash flows for each of the three years in the period
ended December 31, 2001. 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 auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of MacroChem Corporation at December 31, 2001
and 2000, and the results of its operations and its cash flows for each of the
three years in the period ended December 31, 2001 in conformity with accounting
principles generally accepted in the United States of America.

MACROCHEM CORPORATION
NOTES TO FINANCIAL STATEMENTS

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

MacroChem Corporation (the "Company") develops and licenses transdermal drug
delivery compounds and systems intended to promote the delivery of drugs from
the surface of the skin into the skin or the bloodstream.

The Company has been engaged primarily in research and development since its
inception in 1981 and has derived limited revenues from the commercial sale of
its products, licensing of certain technology and feasibility studies. The
Company has had no revenues relating to the sale of any products currently under
development. The Company has incurred net losses every year since its inception
and the Company anticipates that losses may continue for the foreseeable future.
At December 31, 2001, the Company's accumulated deficit was approximately $55.4
million. The Company's ability to continue operations after its current capital
resources are exhausted depends on its ability to obtain additional financing
and achieve profitable operations, as to which no assurances can be given.
However, the Company believes that its financial resources are sufficient to
meet planned operating activities at least through December 31, 2002.

The Company organizes itself as one segment reporting to the chief executive
officer. Products and services consist primarily of research and development
activities in the pharmaceutical industry.

ACCOUNTING ESTIMATES - The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. The primary estimates
underlying the Company's financial statements include the carrying value and
useful lives of the Company's patents and property and equipment, the valuation
allowance established for the Company's deferred tax assets, and the underlying
assumptions to apply the pricing model to value stock options under SFAS No.
123. Management bases its estimates on certain assumptions, which it believes
are reasonable in the circumstances, and while actual results could differ from
those estimates, management does not believe that any change in those
assumptions in the near term would have a significant effect on the financial
position or the results of operations.

FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying amounts of cash equivalents,
marketable securities, accounts receivable, accounts payable and accrued
expenses approximate their fair value because of their short-term nature.
Short-term investments are carried at aggregate fair value.

CONCENTRATION OF RISK - Cash and cash equivalents and short-term investments at
December 31, 2001 and 2000 are primarily comprised of government agency
securities and certificates of deposit. Accounts receivable at December 31, 2001
and 2000 are due from one customer. 100% of revenue for the years ended

30


1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)

December 31, 2001 and 2000 was derived from research contracts with two
customers. 100% of revenue for the year ended December 31, 1999 was derived from
research contracts with one customer.

CASH AND CASH EQUIVALENTS - Cash equivalents consist of short-term, highly
liquid investments with a maturity of three months or less when purchased.

SHORT-TERM INVESTMENTS - The Company has classified its short-term investments
as "available-for-sale" and, accordingly, carries such securities at aggregate
fair value. Fair value has been determined based on quoted market prices. The
cost of such securities approximates fair market value. Short-term investments
are comprised of bank certificates of deposit, with maturities of 4 to 23
months, amounting to $294,730 and $3,261,013 at December 31, 2001 and 2000,
respectively, and a liquid money market mutual fund with a carrying value of
$15,538,098 and $12,917,747 at December 31, 2001 and 2000, respectively.

PROPERTY AND EQUIPMENT - Property and equipment are stated at cost. Depreciation
and amortization are provided on the straight-line method over the estimated
useful lives of the related assets which range from five to ten years.

PATENTS - The Company has filed applications for United States and foreign
patents covering aspects of its technology. Costs and expenses incurred in
connection with pending patent applications are deferred. Costs related to
successful patent applications are amortized over the estimated useful lives of
the patents, not exceeding 20 years, using the straight-line method. Accumulated
costs related to patents or deferred patent application costs that are
considered to have limited future value are charged to expense. Accumulated
amortization aggregated approximately $172,600 and $144,900, respectively, at
December 31, 2001 and 2000. On an on-going basis, the Company evaluates the
recoverability of the net carrying value of various patents by reference to the
patent's expected use in drug and other research activities as measured by
outside interest in the Company's patented technologies and management's
determination of potential future uses of such technologies.

REVENUE RECOGNITION - Revenues are earned and recognized based upon the sale or
licensing of product rights, completion of contractually identified development
milestones, upon shipment of product, upon completion of a contract or upon the
attainment of specific milestones or benchmarks specified in license or
development agreements. Amounts received in advance are recorded as deferred
revenue and are amortized over the life of the agreement or achievement of
milestones. Research revenue associated with the research contracts is billed on
a cost reimbursement basis, which includes direct costs incurred in connection
with research activities and an allocation of certain other costs incurred by
the Company.

RESEARCH AND DEVELOPMENT - Research and development costs are charged to
operations as incurred. Such costs include proprietary research and development
activities and expenses associated with research and development contracts,
whether performed by the Company or contracted with independent third parties.

31



1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)

STOCK BASED COMPENSATION - The Company has elected to continue to use the
intrinsic value based method to account for employee stock option awards under
the provisions of Accounting Principles Board No. 25, "Accounting for Stock
Issued to Employees," and provides disclosures based on the fair value method in
the notes to the financial statements as permitted by SFAS No. 123, "Accounting
for Stock-Based Compensation."

Stock or other equity based compensation for non-employees must be accounted for
under the fair value based method as required by SFAS No. 123 and Emerging
Issues Task Force No. 96-18, "Accounting for Equity Instruments That Are Issued
to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or
Services". Under this method, the equity based instrument is valued at either
the fair value of the consideration received or of the equity instrument issued
on the date of grant. The resulting compensation cost is recognized and charged
to operations over the service period or the vesting period, whichever is
shorter.

INCOME TAXES - The Company accounts for income taxes in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting for
Income Taxes", which requires the use of the liability method. The objective of
this method is to establish deferred tax assets and liabilities for the
temporary differences between the financial reporting basis and the tax basis of
the Company's assets and liabilities using tax rates in effect in the year(s) in
which the differences are expected to reverse.

NET INCOME (LOSS) PER SHARE - Basic earnings per share is computed using the
weighted average number of common shares outstanding during each year. Diluted
earnings per common share reflect the effect of the Company's outstanding
options and warrants, except where such items would be anti-dilutive. Due to the
net losses reported in 2001, 2000 and 1999, basic and diluted per share amounts
are the same. For the years ended December 31, 2001, 2000 and 1999 potential
common shares are not included in the per share calculations for diluted EPS,
because the effect of their inclusion would be anti-dilutive. Anti-dilutive
potential shares not included in per share calculations for 2001, 2000 and 1999
were approximately 4,791,000, 4,761,000 and 3,999,000 shares, respectively.

NEW ACCOUNTING PRONOUNCEMENTS - In 1998, the Financial Accounting Standards
Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133"). SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives), and for hedging
activities. The adoption of SFAS No. 133 on January 1, 2001 had no impact on the
Company's financial statements.


In June 2001, the FASB issued two new pronouncements: SFAS No. 141, Business
Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No.
141 is effective as follows: a) use of the pooling-of-interest method is
prohibited for business combinations initiated after June 30, 2001; and b) the
provisions of SFAS No. 141 also apply to all business combinations accounted for
by the purchase method that are completed after June 30, 2001 (that is, the date
of acquisition is July 2001 or later). There are also transition provisions

32


1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)

that apply to business combinations completed before July 1, 2001, that were
accounted for by the purchase method. SFAS No. 142 is effective for fiscal years
beginning after December 15, 2001 to all goodwill and other intangible assets
recognized in an entity's statement of financial position at that date,
regardless of when those assets were initially recognized. SFAS No. 142 requires
that upon adoption, amortization of these assets will cease and instead, the
carrying value of goodwill and other intangible assets with indefinite lives
will be evaluated for impairment on an annual basis. On January 1, 2002, the
Company adopted these statements which will have no effect on the Company's
financial position or results of operations.

In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" ("SFAS No. 144"), which addresses financial
accounting and reporting for the impairment or disposal of long-lived assets.
This Statement supercedes SFAS No. 121, and the accounting and reporting
provisions of APB 30, for the disposal of a segment of a business. The
provisions of SFAS No. 144 are required to be adopted by the Company effective
January 1, 2002. On January 1, 2002, the Company adopted this statement which
will have no effect on the Company's financial position or results of
operations.

AUTHORIZED CAPITAL STOCK - Authorized capital stock consists of 60,000,000
shares of $.01 par value common stock of which 28,158,054 shares are issued
(27,904,708 are outstanding) and 5,629,013 are reserved for issuance upon
exercise of common stock options and warrants at December 31, 2001. Authorized
and unissued preferred stock totals 6,000,000 shares, of which 600,000 shares
have been designated Series B Preferred Stock. During 1998, the Company's Board
of Directors authorized the repurchase of up to 1,000,000 shares of common stock
at market price. The Company repurchased 0, 120,500 and 32,500 common shares in
2001, 2000 and 1999, respectively. At December 31, 2001, 253,346 repurchased
shares remain available for future use and 679,587 shares are available to be
repurchased.

WARRANTS - During 2001, institutional investors received warrants to purchase an
aggregate of 313,209 shares of common stock at a purchase price of $8.995 per
share expiring in five years in connection with a private placement. The
warrants are callable by the Company if the closing price of the stock is higher
than $17.99 for 15 consecutive trading days at any time before expiration. As of
December 31, 2001, none of the $8.995 warrants had been exercised.

During 2000, as part of a financing, two institutional investors received
warrants to purchase an aggregate of 363,322 shares of common stock at a

investors received a warrant to purchase additional shares at a purchase price
of $.01 per share exercisable only upon certain conditions relating to the
trading price of the common stock during the period following December 12, 2000.
The warrants may be exercised on a cashless basis. Through March 9, 2001,
379,892 of the $0.01 warrants had been exercised. The placement agent received a
warrant to purchase 108,999 shares of common stock at a purchase price of $7.43
per share expiring in five years.

In 1996, in connection with services performed for the Company, the firm of
Janssen-Meyers, L.P. received a warrant, exercisable immediately and expiring
June 17, 1999, for the purchase of 145,800 shares of the Company's common stock
at a price of $6.075 per share. During 1999 137,319 of these warrants were
exercised for aggregate proceeds of $834,214 and 2,139 warrants expired.

All options granted during the three year period ended December 31, 2001 were
granted at the market price of the stock. Also, in June 2000, the Company
extended the exercise period for 620,000 options that were previously issued to
two former officers under the 1984 Non-Qualified Stock Option Plan, resulting in
a non-cash stock compensation charge to operations of $2,809,532.

The fair value of options on their grant date was measured using the
Black/Scholes option pricing model. Key assumptions used to apply this pricing
model are as follows:



2001 2000 1999
---- ---- ----


Risk-free interest rate 4.38%-5.27% 5.67%-6.57% 5.01%-6.46%
Expected life of option grants 6 years 6 years 6 years
Expected volatility of underlying stock 128% 72%-82.18% 62.5%-95.6%
Expected dividend payment rate, as a
percentage of the stock price on
the date of grant --- --- ---


The weighted average fair values of options granted during 2001, 2000 and 1999
were $ 3.42, $4.30 and $5.53, respectively.

The option pricing model used was designed to value readily tradable stock
options with relatively short lives. The options granted to employees are not
tradable and have contractual lives of up to ten years.

The Company uses the intrinsic value method to measure compensation expense
associated with grants of stock options to employees. Had the Company used the
fair value method to measure compensation, the reported net loss and basic and
diluted net loss per share would have been as follows:



2001 2000 1999
---- ---- ----


Net loss as reported $(12,333,243) $( 9,745,358) $(6,787,070)

Compensation costs ( 2,196,840) ( 3,846,761) (2,270,636)

SHAREHOLDER RIGHTS PLAN - The Company has adopted a shareholder rights plan. The
Company declared a dividend consisting of one Right for each share of common
stock outstanding on September 10, 1999. Stock issued after that date will be
issued with an attached Right.

Each Right entitles the holder, upon the occurrence of certain events, to
purchase 1/100th of a share of Series B Preferred Stock of the Company at an
initial exercise price of $50.00, subject to adjustments for stock dividends,
splits and similar events. The Rights are exercisable only if a person or group
acquires 20% or more of the Company's outstanding common stock, or announces an
intention to commence a tender or exchange offer, the consummation of which
would result in ownership by such person or group of 20% or more of the
Company's outstanding common stock.

The Board of Directors may, at its option after the occurrence of one of the
events described above, exchange all of the then outstanding and exercisable
Rights for shares of common stock at an exchange ratio of one share of common
stock per Right.

The Board of Directors may redeem the Rights at the redemption price of $0.01
per Right at any time prior to the expiration of the rights plan on August 13,
2009. Distribution of the Rights is not a taxable event to shareholders.

The Board of Directors has authorized 600,000 shares of Series B Preferred
Stock.

5. COMMITMENTS AND CONTINGENCIES

LEASE COMMITMENTS - The Company leases office space under an agreement expiring
in 2005. The lease includes payment increases over the term of the agreement.
The total amount of the lease payments is being charged to expense using the
straight-line method over the term of the agreement. The Company has recorded
deferred rent to reflect the excess of rental expense over cash payments since
the inception of the agreement. Future minimum payments under the agreement are
as follows:

2004 465,300

key employee agreement provide that the employee is an employee at-will. The
terms of the consulting agreements do not exceed one year. These agreements
provide for annual payments of approximately $1,329,000.

6. INCOME TAXES

No income tax provision or benefit has been provided for federal or state income
tax purposes as the Company has incurred losses since inception. As of December
31, 2001, the Company has available net operating loss carryforwards of
approximately $50.2 million for federal income tax purposes, expiring through
2021 and $33.3 million for state income tax purposes, expiring through 2006. In
addition, the Company has unused investment and research and development tax
credits for federal and state income tax purposes aggregating $1,248,700 and
$755,100, respectively. The use of the federal net operating loss may also be
restricted due to changes in ownership in accordance with definitions as stated
in the Internal Revenue Code.

The net tax effect of differences in the timing of certain revenue and expense
items and the related carrying amounts of assets and liabilities for financial
reporting and tax purposes are not material and, accordingly, are not displayed
in the table below. The components of the Company's deferred tax assets as of
December 31, 2001 and 2000 are as follows:


2001 2000
---- ----
Deferred Tax Assets:

For the years ended December 31, 2001, 2000 and 1999, the valuation allowance
was increased by approximately $5,054,000, $2,288,000 and 3,006,200,
respectively, due to the uncertainty of future realization of currently
generated net operating loss and tax credit carryforwards.
