OVERVIEW

     We are a specialty pharmaceutical company that develops and seeks to
commercialize pharmaceutical products. Currently, our portfolio of product
candidates is based on our proprietary drug delivery technologies: SEPA,
MacroDerm and DermaPass. Our patented SEPA topical drug delivery technology
(SEPA is an acronym for "Soft Enhancement of Percutaneous Absorption," where
"soft" refers to the reversibility of the skin effect of the technology, and
"percutaneous" means "through the skin") enhances the efficiency and rate of
diffusion of drugs into and through the skin. We own a composition of matter
patent on the SEPA family of compounds, which will expire in November 2006. We
also own five composition of matter and use patents, with expiration dates
ranging from 2015 to 2019, for the combination of SEPA with numerous existing
classes of drugs, including antifungals and human sex hormones. Our patented
MacroDerm drug delivery technology encompasses a family of low to moderate
molecular weight polymers that impede dermal drug or chemical penetration, which
may be usable, for example, to prevent chemicals in insect repellant from
penetrating the skin. We own three patents covering the composition of matter
and methods of use of our MacroDerm polymers that expire in 2015. We have also
filed a patent application for our DermaPass family of transdermal absorption
enhancers that have a different drug delivery profile than SEPA, which we
believe could be used with a wider range of active pharmaceutical ingredients.

     Our lead product candidate is EcoNail, a topically applied SEPA-based
econazole lacquer for the treatment of onychomycosis, a condition commonly known
as nail fungus. Econazole, a commercially available topical antifungal agent
most commonly used to treat fungal skin infections, inhibits in vitro growth of
the fungi most commonly implicated in onychomycosis. When used in EcoNail, SEPA
works by allowing more rapid and complete release of econazole from the lacquer
into and through the nail plate. In a pre-clinical study using human cadaver
nails, EcoNail delivered through the nail more than 14,000 times the minimum
concentration of econazole needed to inhibit the fungi most commonly associated
with onychomycosis. Following our laboratory studies, we conducted a randomized,
double blind controlled Phase 1 tolerance/human exposure trial of EcoNail in
eighteen patients with onychomycosis of the toenails. In this study, EcoNail was
well tolerated, and investigators reported no serious drug-related adverse
events. Serum assays used to determine the level of drug in the bloodstream
showed no detectable levels of econazole, further supporting EcoNail's systemic
safety profile. Full data from the 18-week trial were presented in May 2005 at
the annual meeting of the Society for Investigative Dermatology. We have a
composition of matter and use patent covering EcoNail that will expire in 2019.

     We expect to commence a Phase 2 efficacy study of EcoNail in the second
quarter of 2006. We contemplate that this study will be conducted through a
contract research organization with significant experience in onychomycosis
trials.

                                       4


     Our other clinical stage product candidate, Opterone, is a topically
applied SEPA-based testosterone cream designed to treat male hypogonadism. Male
hypogonadism is a condition in which men have levels of circulating testosterone
below the normal range and may exhibit one or more associated symptoms,
including low energy levels, decreased sexual performance, loss of sex drive,
increased body fat or loss of muscle mass. We believe Opterone has significant
advantages over other testosterone delivery methods and that its formulation as
a cream should avoid an oily feel as well as application and cosmetic concerns
reported by some users of gel formulations. To the best of our knowledge,
Opterone is the first and only clinical development stage testosterone cream. In
August 2004, we announced the completion of a pharmacokinetics study of Opterone
in hypogonadal males. In May 2005, we announced results from a bioavailability
study of Opterone. In that study, patients using a 2.5 gram dose of Opterone
applied to the upper arms and shoulders reached the natural physiologic range of
testosterone levels over a 24-hour period. In December 2005, we received a
letter from the Division of Reproductive and Urologic Products of the U.S. Food
and Drug Administration, or FDA, in response to questions posed by us regarding
a proposed Phase 3 clinical program for Opterone. In the letter, the FDA
requested that we conduct additional investigation into multiple dose safety and
pharmacokinetics before beginning any eventual Phase 3 protocol. The additional
investigation and Phase 3 revisions will increase the time and expense
associated with the development of Opterone. The next step in the development
process for Opterone is a Phase 2 trial. We are seeking a partner to advance
development of this product candidate. We may elect not to develop Opterone
further if we cannot find a partner. We have a composition of matter and use
patent covering Opterone that will expire in 2017.

     In addition to EcoNail and Opterone, we are evaluating several earlier
stage product candidates. We have developed and tested SEPA-based formulations
to deliver other active pharmaceutical ingredients including topical anesthetic
and topical non-steroidal anti-inflammatory drugs (NSAIDs). We have also tested
application of our MacroDerm polymers for use with cosmetics, pharmaceuticals
and consumer products like insect repellants and sunscreens to decrease skin
penetration and/or improve persistence on the skin. For example, our laboratory
data demonstrated that, when formulated with the insect repellant DEET,
increasing concentrations of MacroDerm reduces the amount of DEET that is
absorbed through human skin. We have performed initial laboratory experiments to
test the ability of DermaPass to improve transdermal delivery of various active
pharmaceutical ingredients.

     Since inception, our primary source of funding for our operations has been
the private and public sale of our securities. On August 31, 2005, due to our
financial condition at the time and our inability to raise sufficient capital to
maintain operations, we discontinued all research and development activities and
terminated substantially all of our non-management personnel. In December 2005
and February 2006, we raised an aggregate of $8.25 million in a private
placement of our securities to institutional investors. As a result of this
private placement, we have begun to resume operations with a focus on advancing
clinical development of our lead product, EcoNail. 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.

OUR STRATEGY

     Our strategy is to become a leading provider of specialty pharmaceuticals
by innovating, developing and commercializing a portfolio of products through
the use of our proprietary drug delivery technologies, strategic partnering, or
in-licensing other products or technologies. Key elements of our strategy
include:

  o  CONTINUE CLINICAL DEVELOPMENT OF OUR LEAD PRODUCT CANDIDATE, ECONAIL.
     In the near-term, we intend to focus most of our resources on
     conducting and completing clinical trials of our EcoNail product
     candidate.
  o  CREATE VALUE THROUGH STRATEGIC PARTNERSHIPS. Where appropriate, we
     intend to seek partners to facilitate the development and
     commercialization of our product candidates. In the near term, we plan
     to seek a partner to advance development of our Opterone product
     candidate.
  o  IN-LICENSE SELECTED PRODUCTS AND TECHNOLOGIES. We intend to identify
     and inlicense products and technologies to complement and expand our
     portfolio of product candidates.
  o  LEVERAGE AND EXPAND OUR EXISTING TECHNOLOGIES TO DEVELOP NEW PRODUCTS.
     We believe pharmaceuticals and certain other commercial products used
     on the skin may be formulated using our proprietary drug delivery
     technologies and could have applications in the treatment of other
     diseases and conditions. We will seek to identify new product
     candidates by selecting and developing additional pharmaceuticals and
     skin products that can be combined effectively with our technologies.

OUR DRUG DELIVERY TECHNOLOGIES

     To be effective, drugs must reach an intended site in the body, at an
effective concentration, and for an appropriate length of time. Currently, the
vast majority of drugs are administered either orally or by injection. However,
there are numerous drugs for which these modes of administration are not well
suited. For example, oral administration of certain drugs may result in
irritation of the gastro-intestinal tract or undesirable rapid first pass
metabolism. First pass metabolism, which refers to the chemical breakdown of
compounds in the liver and gastro-intestinal tract, can result in a significant
reduction in the amount of drug reaching its intended site of activity in the
body. In some cases, liver damage may occur due to the toxicities associated
with the breakdown of a particular drug. In the case of injectable drugs,
administration may be painful and in many cases requires frequent and costly
office visits to treat chronic conditions.

     One alternative method of administering drugs is topical delivery. Topical
delivery works by either introducing drugs into the skin (dermal delivery) for
the treatment of dermatologic or localized conditions and diseases, or through
the skin (transdermal delivery) and into the bloodstream for the treatment of
systemic conditions and diseases. Topical drug delivery has several advantages.
For example, topical drug delivery:

      o  helps to avoid inactivation of a drug caused by first pass metabolism
         in the liver and gastro-intestinal tract;
      o  can provide local delivery of appropriate concentrations of a drug to
         the intended site of action without systemic exposure;


                                       6


      o  helps avoid gastro-intestinal distress caused by ingesting a drug; and
      o  simplifies drug administration to patients who have difficulty
         swallowing oral dosage forms or who do not wish to endure the
         discomfort of injections.

SEPA DRUG DELIVERY TECHNOLOGY

     Delivering drug molecules through the skin is challenging. The skin
naturally serves as the primary barrier that prevents outside organisms,
chemicals and toxins from easily entering the body. Human skin is made up of two
layers: the outer layer or epidermis (which includes the stratum corneum) and
the inner layer or dermis. The stratum corneum acts as the main barrier to drug
delivery. The stratum corneum consists of corneocytes, which are dead, flattened
skin cells filled with keratin, and a lipid matrix, which is made up of
multi-layered oily molecules that hold the corneocytes together in a sheet.

     Our SEPA drug delivery technology is a family of patented compounds that
can enhance the transport, penetration and controlled delivery of a wide range
of drugs through the skin. We have chosen SEPA 0009, a member of the SEPA
family, for clinical development. SEPA enhances transdermal drug delivery by
temporarily and reversibly disrupting the alignment of the lipid bilayer within
the lipid matrix in the stratum corneum. This disruption renders the skin
temporarily permeable, allowing a drug to diffuse through the stratum corneum in
the epidermis, and then into and through the dermis, where it can enter the
bloodstream through the capillaries.

     SEPA possesses the following attributes:

          o REVERSIBLE: The alignment of the lipid bilayer within the lipid
            matrix in the stratum corneum reverts back to normal after SEPA has
            diffused through it without causing permanent changes to the skin.

          o RAPIDLY METABOLIZED: The human body rapidly metabolizes SEPA into
            ethylene glycol and decanoic acid, two metabolites well understood
            by regulatory agencies.

          o CHEMICALLY NON-REACTIVE: SEPA does not react chemically with most
            other organic molecules and, as a result, is compatible with a wide
            range of active pharmaceutical ingredients.

          o VERSATILE: The rate and amount of drug absorbed by the skin or body
            in a SEPA-based formulation can be controlled by varying the
            components in the formulation.

     SEPA, when properly combined with active pharmaceutical ingredients, may
provide for a variety of convenient and easy-to-apply formulations, including
creams, gels, ointments, lacquers and solutions for the treatment of a wide
range of systemic and localized conditions. We believe that products
incorporating SEPA may allow selected drugs to be administered more effectively
and with improved patient compliance compared to alternative methods of drug
administration, such as ingestion and injection.

                                       7


MACRODERM DRUG DELIVERY TECHNOLOGY

     For chemicals that penetrate the skin too readily or that can be toxic if
significantly absorbed into the bloodstream, it may be desirable to retard the
rate of drug absorption to achieve an optimal delivery profile. For these
chemicals, we have developed our second drug delivery technology, called
MacroDerm, encompassing a series of low to moderate molecular weight polymers
that impede drug penetration through the skin. We believe MacroDerm may have
uses in cosmetics, personal care products and selected pharmaceuticals.
Potential applications include their formulation with sunscreens, moisturizers
and insect repellents to decrease skin penetration and improve persistence on
the skin. We have synthesized MacroDerm prototypes and we are seeking strategic
partners to evaluate, manufacture and market specific MacroDerm products.

NEW TRANSDERMAL DRUG DELIVERY TECHNOLOGY

     We have also filed a patent application for DermaPass, a new family of
enhancers that we believe can be used with a wider variety of active
pharmaceutical ingredients than SEPA. We have performed initial laboratory
experiments to test the ability of DermaPass to improve transdermal delivery of
various active pharmaceutical ingredients.

OUR LEAD PRODUCT CANDIDATE: ECONAIL FOR ONYCHOMYCOSIS

     Onychomycosis, a fungal infection of the nail, is predominantly an
infection of the toe nail bed and nail plate underlying the surface of a nail.
Typical symptoms of onychomycosis can include:

      o  nail discoloration;
      o  nail thickening;
      o  cracking and fissuring of the nail plate; and
      o  in severe cases, inflammation, pain and secondary infection of the nail
         bed and adjacent skin.

     According to FITZPATRICK'S DERMATOLOGY IN GENERAL MEDICINE (SIXTH EDITION),
onychomycosis is a common disease, the prevalence of which varies by geographic
region and ranges from approximately 2% to 18% of the worldwide population, with
up to 48% of the population experiencing onychomycosis at least once by age 70.
According to an article published in 2000 in the JOURNAL OF THE AMERICAN ACADEMY
OF DERMATOLOGY, a large scale study found that the prevalence of onychomycosis
in the normal population of North America was approximately 14%.

     CURRENT TREATMENTS AND THEIR SHORTCOMINGS

     Current treatment options for onychomycosis include oral drugs, debridement
(filing, trimming and scraping), nail avulsion (surgical or chemical excision of
the infected nail plate) and topical drug therapies. There are two oral
therapies marketed for the treatment of onychomycosis in the U.S.: Lamisil and
Sporanox. The leading oral treatment, Lamisil, has a complete cure rate of
approximately 38%, but also has a 15% relapse rate. Sporanox has a complete cure
rate of approximately 14%. Complete cure refers to mycological cure, or


                                       8


simultaneous occurrence of a negative KOH (a potassium hydroxide staining method
for direct microscopic examination of nail scrapings) and a negative fungal
culture, plus clinical cure, or clearance of all signs of infection. One risk
associated with each of the oral treatments, both of which undergo substantial
first pass metabolism by the liver, is liver disease. As a result, patients must
continually monitor their liver function for signs of failure, including
fatigue, anorexia, nausea and/or vomiting, jaundice, dark urine or pale stools.
Such monitoring typically requires blood tests and associated office visits,
which can impact patient compliance. In the rare case that liver failure occurs,
it can result in death or the need for a liver transplant. Mechanical
debridement, which is a traditional podiatric approach to onychomycosis that
reduces the thickness of the nail, is not a cure for onychomycosis and requires
time, specialized instruments and experience. Nail avulsion, which requires
surgical or chemical removal of the nail plate causes discomfort and traumatizes
the nail bed.

     TOPICAL ADMINISTRATION

     The only topical onychomycosis drug currently marketed in the U.S. is
Penlac(R), a nail lacquer which has a complete cure rate of less than 10% and
requires up to 48 weeks of treatment, including periodic removal of any
unattached infected nail by a health care professional.

     THE ECONAIL APPROACH

     Topically delivered lacquer formulations, like EcoNail, have specific
advantages over other existing treatments because they are applied like nail
polish, treat fungal nail infections locally, and facilitate close and extended
contact between an antifungal drug and the outer, or dorsal, nail surface.
Developers of topical nail lacquers for onychomycosis face two major challenges.
First, lacquers with acceptable hardness, durability and drying time tend not to
release antifungal drugs from the lacquer matrix readily. Second, most
antifungal drugs do not penetrate into the deep, or ventral, nail plate
adequately when applied to the outer, or dorsal, nail surface, which results in
insufficient antifungal concentrations at the site of infection.

     EcoNail is a topically applied lacquer formulation containing econazole and
SEPA for the topical treatment of onychomycosis. Econazole, a topical antifungal
agent, effectively inhibits IN VITRO growth of the fungi most commonly
implicated in onychomycosis. In contrast to SEPA's action in disrupting the
lipid bilayer of the skin, SEPA as used in EcoNail works to soften the lacquer
in which econazole is contained, thereby allowing for more rapid and complete
release of econazole from the lacquer into and through the nail. A 14-day study
of lacquers containing radioactively labeled econazole on human non-diseased
cadaver nails demonstrated that EcoNail delivered approximately seven times more
econazole to the ventral nail and 200 times more econazole to the nail bed than
a similar lacquer without SEPA. In this study, EcoNail delivered to the ventral
nail more than 14,000 times the minimum concentration of econazole needed to
inhibit the two most common fungi associated with onychomycosis. In addition, we
believe that EcoNail, as a locally applied lacquer, will have a reduced risk of
systemic side effects compared with oral treatments for onychomycosis.


                                       9


CLINICAL DEVELOPMENT

     Following our laboratory studies, we conducted a Phase 1 tolerance/human
exposure clinical trial of EcoNail in patients with onychomycosis and released
six week safety and tolerance data from that trial in November 2004. The trial
was a randomized, double-blind, controlled Phase 1 trial conducted at two U.S.
clinical sites. Eighteen patients with onychomycosis of the toenails completed
the safety-tolerability segment of the study, in which all fingernails and
toenails were treated twice daily for six weeks with either EcoNail or a control
nail lacquer. The six week safety-tolerability segment was followed by an
open-label segment of the trial in which all patients received EcoNail applied
once daily to all nails for an additional 12 weeks to extend patient exposure
experience.

     The main objectives of this Phase 1 study were to test the safety and local
tolerability of EcoNail in patients with onychomycosis and to determine systemic
exposure to econazole. In this study, EcoNail was well tolerated, and
investigators reported no serious drug-related adverse events. Serum assays
showed no detectable levels of econazole, further supporting EcoNail's systemic
safety profile.

     Full data from the 18 week trial were presented in May 2005 at the annual
meeting of the Society for Investigative Dermatology. As the next step in the
clinical development of EcoNail, we plan to commence a Phase 2 efficacy study in
the second quarter of 2006.

OTHER PRODUCT CANDIDATES

OPTERONE FOR HYPOGONADISM

     Hypogonadism is a condition in which the testes produce insufficient
amounts of testosterone, a hormone responsible for normal growth and development
of the male sex organs and for maintenance of secondary male sex
characteristics. Hypogonadism is generally characterized by serum testosterone
levels of less than 300 nanograms per deciliter together with one or more of the
following signs or symptoms:

     o low energy levels;
     o decreased sexual performance;
     o loss of sex drive;
     o increased body fat;
     o loss of muscle mass;
     o reduced bone density; and
     o mild depression.

     According to the Endocrine Society, this disorder affects an estimated four
to five million men in the United States, approximately 200,000 of whom receive
hormone replacement therapy. According to a 2001 article published in THE
JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM, the incidence of hypogonadal
testosterone levels in U.S. males increases from approximately 20% in men over
the age of 60 to approximately 50% in men over the age of 80.


                                       10


     Diagnosis of testosterone-deficiency often occurs when a patient seeks
treatment for other conditions or symptoms. Routine testing of testosterone
levels has become a more common part of men's health evaluations by specialists,
although testosterone testing is still relatively new among the majority of
primary care physicians.

     CURRENT TREATMENTS AND THEIR SHORTCOMINGS

     Currently available treatment options for hypogonadism in the U.S. include
testosterone delivered via intramuscular injections, transdermal patches, buccal
tablets that are placed between the cheek and gum, and topical gels. Each of
these treatments, however, has certain disadvantages. Intramuscular injections
are often painful, require a medical office visit, and cause rapid increases in
circulating testosterone to supraphysiological levels within days of
administration, followed by rapid decreases. Patients often report severe acne,
unwanted hair growth, and increased aggression shortly after a testosterone
injection. Testosterone patches may be inconvenient to apply, can cause severe
skin irritation and require frequent rotation of the application site to avoid
skin lesions. The resulting discomfort can potentially reduce patient compliance
with the treatment. Buccal tablets, which must be applied twice daily between
the cheek and gum, can become displaced or swallowed and can cause taste
perversion and gum irritation. Topical gels, while more convenient to use than
other treatments, can require application of a large volume of product to the
patient's body, often drip during application or run when applied to the skin
and can produce an oily feel on the skin.

     THE OPTERONE APPROACH

     Opterone is our topically applied cream formulation of 1% testosterone and
SEPA. To the best of our knowledge, Opterone is the first and only clinical
development stage testosterone cream. In both laboratory and clinical settings,
we demonstrated that SEPA enhances the absorption of testosterone through the
skin. IN VITRO studies using human cadaver skin showed that our enhanced cream
formulation delivered two to three times more testosterone transdermally over a
24-hour period when compared to equivalent doses of the currently marketed gel
products. These IN VITRO studies also suggested that our enhanced cream
formulation may deliver comparable amounts of testosterone in smaller dose
volumes than currently marketed gel products. In addition, we believe that the
creamy texture and consistency, the non-oily feel and the other physical
attributes of Opterone cream will provide a more cosmetically pleasing
application than available gel treatments.

     CLINICAL DEVELOPMENT

     In August of 2004, we announced the top-line results of a pharmacokinetics
study of Opterone. The trial was designed to study the pharmacokinetics of
testosterone following administration of Opterone to hypogonadal adult males.
Thirty-two patients were randomized to receive one of three dose volumes of
Opterone, with all patients completing the assigned dosing regimen. In this
study, Opterone delivered testosterone into the bloodstream within the first few
hours of application and also provided a more sustained delivery of testosterone
over 24 hours compared to our prior gel formulation. We also observed that
Opterone was generally well tolerated with no patients dropping out of the study
due to adverse events. Local application site symptoms, when observed, were mild
to moderate and transient. Full data from the study were presented in June 2005


                                       11


at the 8th International Congress of Andrology in Seoul, Korea. The results of
this dose proportionality study guided the design of a bioavailability study,
the next step in the clinical development plan.

     In December 2004, we initiated a bioavailability study of Opterone. Results
from this trial were announced in May 2005. In the study, patients receiving a
2.5 gram dose of Opterone applied to the upper arms and shoulders, half the
amount of the recommended starting dose of currently marketed gel products,
reached the natural physiologic range of testosterone levels over a 24-hour
period. Within the trial, the treatment group receiving 2.5 grams of Opterone
applied to the upper arms and shoulders reached an average maximum circulating
total testosterone level of 577 ng/dL, while the three treatment groups in the
study ranged from 408 to 577 ng/dL. Typical circulating total testosterone
levels range from 300 to 1000 ng/dL. Opterone was well tolerated in the trial
with only mild adverse events, the most common being headache and mild
application site reaction.

     On December 5, 2005, we received a response from the Division of
Reproductive and Urologic Products at the FDA to questions posed by us regarding
the proposed Phase 3 clinical program for Opterone. In the response, the FDA
reiterated its concerns regarding the skin irritation potential of SEPA related
to pre-clinical studies of SEPA, including without limitation, a 26-week
transgenic-mouse (Tg.AC) carcinogenicity study of SEPA. To address these
concerns as well as other issues related to Opterone's safety and efficacy
program, the FDA requested that we conduct additional investigation into
multiple dose safety and pharmacokinetics before beginning any eventual Phase 3
study. The FDA also requested that we revise our proposed Phase 3 protocol to
include additional patients and to extend patient exposure and safety follow-up.
The additional investigation and Phase 3 revisions will increase the time and
expense associated with the development of Opterone. Accordingly, the next step
in the development process for Opterone is a Phase 2 trial. We are seeking a
partner to advance development of this product candidate. We may elect not to
develop Opterone further if we cannot find a partner.

EARLIER STAGE PRODUCT CANDIDATES

     We have also tested a number of formulations containing our proprietary
drug delivery technologies combined with various active pharmaceutical
ingredients. As we continue to build our product candidate portfolio, we review
our pre-clinical-stage product opportunities to identify those that show
sufficient promise to be advanced into clinical development. We evaluate each
new product candidate on its potential for success based on both scientific and
commercialization criteria. These criteria include:

     o  technical feasibility (formulation, product stability and laboratory
        results);
     o  likelihood of laboratory results translating into a meaningful clinical
        benefit;
     o  expected clinical studies needed and the regulatory pathway required to
        obtain marketing approval;
     o  determination of the product candidate's expected competitive advantage
        in the marketplace;
     o  duration of development timeline leading to commercialization;


                                       12


     o  financial investment needed for development and availability of
        necessary financial resources; and
     o  expected sales and profitability.

COMPETITION

     We compete with a number of companies, 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 Bentley Pharmaceuticals, Inc., Biosante Pharmaceuticals, Inc., NexMed,
Inc., ALZA Corporation, Connetics Corporation, Antares Pharma, Inc. and Barrier
Therapeutics, Inc. Established competitors in the therapeutic areas that our
clinical stage product candidates seek to address include, with respect to
onychomycosis, Novartis AG, Johnson & Johnson and Sanofi Aventis (Dermik
Laboratories), and with respect to male hypogonadism, Solvay Pharmaceuticals,
Inc., Auxilium Pharmaceuticals, Inc., Watson Pharmaceuticals, Inc. and Columbia
Laboratories, Inc. Compared with us, these companies have or may have
substantially greater capital resources, research and development and technical
staff, facilities and experience in obtaining regulatory approvals, as well as
in manufacturing, marketing and distribution of products.

     With respect to onychomycosis, Novartis AG and Johnson & Johnson each offer
an orally administered antifungal therapy and Sanofi Aventis (Dermik
Laboratories) offers a topical nail lacquer therapy for treating fungal
infections of the nail. A number of other companies, including Nexmed, Inc. and
MediQuest Therapeutics, Inc., are also developing topical and oral therapies for
these infections.

     With respect to male hypogonadism, Solvay Pharmaceuticals, Inc. and
Auxilium Pharmaceuticals, Inc. each offer a topically administered testosterone
gel, Watson Pharmaceuticals, Inc. offers a testosterone patch, and Columbia
Laboratories, Inc. offers a testosterone buccal film product. A number of other
companies are also developing topical testosterone products.

     We expect any products approved for sale to compete primarily on the basis
of efficacy, safety, patient compliance, reliability, convenience, price and
patent position. Generally, the first pharmaceutical product to reach the market
in a therapeutic or preventive area often has a significant commercial 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.

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.

                                       13

     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,
clinical 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 generally compiled into an NDA or Abbreviated New
Drug Application (ANDA) and submitted to the FDA for approval to market.

     Pre-clinical 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 1 trials typically consist of testing
of the product in a small number of normal volunteers primarily for safety. In
Phase 2, in addition to safety, the efficacy of the product is typically
evaluated in a small patient population. Phase 3 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 4 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 can result in
substantial delay and expense.

     The results of the pre-clinical 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


                                       14


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. For example, an ANDA
may be available for a new topical 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 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. Moreover,
differing reimbursement regulations in various foreign countries may affect
pricing of our drug candidates.

     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.

RESEARCH AND DEVELOPMENT

     In August 2005, at the direction of our board of directors, we discontinued
all research and development activities and terminated substantially all of our
non-management personnel. Following this staff reduction, in order to conduct
research and development activities, including stability studies, tests of our


                                       15


unique formulations and the design of manufacturing processes for our drug
delivery technologies, we will need to contract with third parties to perform
this work. We believe that there are numerous third party contractors who would
be able to perform such research and development activities.

     Prior to the staff reduction in August 2005, we conducted our research and
development activities through our own staff and facilities, and also through
collaborative arrangements with universities, contract research organizations
and independent consultants. Research and developmental expenditures were
$2,938,026, $4,221,039 and $2,291,721 during the years ended December 31, 2003,
2004 and 2005, respectively. We also rely upon third parties to conduct clinical
studies and to obtain FDA and other regulatory approvals.

PATENTS, TRADEMARKS AND LICENSE RIGHTS

     We own a composition of matter patent on the SEPA family of compounds,
which will expire in November 2006. We also own five composition of matter and
use patents, with expiration dates ranging from 2015 to 2019, for the
combination of SEPA with numerous existing classes of drugs, including
antifungals and human sex hormones. The patent for SEPA combined with
antifungals covers the combination of SEPA and econazole in EcoNail, and the
patent for SEPA combined with human sex hormones covers the combination of SEPA
and testosterone in Opterone.

     With respect to our MacroDerm technology, we have three U.S. patents
covering the chemical composition and use of the MacroDerm polymers, which
expire in 2015.

     We intend to seek other composition of matter and use patents regarding
various formulations based on our drug delivery technologies and for new
technologies. In 2005, we filed two new U.S. patent applications: one for the
combination of absorption enhancers with certain active pharmaceutical
ingredients for treatment of skin disorders and the other for improved delivery
of testosterone.

     In addition to the patent activity, we have trademarks for the marks SEPA
and Opterone. We also have pending trademark applications for the marks
MacroDerm and EcoNail.

     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 and trademark
protection. 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.

EMPLOYEES

     As of December 31, 2005, we had four full time employees, none of whom are
dedicated 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.


                                       16


MANUFACTURING

     In order to manufacture our product candidates for clinical trials and for
commercial distribution following FDA approval, we will need to contract with a
third party manufacturer to produce the product. We believe that there are
numerous third party manufacturers who would be able to manufacture our product
candidates for clinical trial purposes and on a commercial scale.

ITEM 1A. RISK FACTORS.

INVESTING IN OUR COMMON STOCK IS RISKY. IN ADDITION TO THE OTHER INFORMATION IN
THIS ANNUAL REPORT ON FORM 10-K, YOU SHOULD CONSIDER CAREFULLY THE FOLLOWING
RISK FACTORS IN EVALUATING US AND OUR BUSINESS. IF ANY OF THE EVENTS DESCRIBED
IN THE FOLLOWING RISK FACTORS WERE TO OCCUR, OUR BUSINESS, FINANCIAL CONDITION
OR RESULTS OF OPERATIONS LIKELY WOULD SUFFER. IN THAT EVENT, THE TRADING PRICE
OF OUR COMMON STOCK COULD DECLINE, AND YOU COULD LOSE ALL OR A PART OF YOUR
INVESTMENT.

                          RISKS RELATED TO OUR BUSINESS
                          -----------------------------

WE HAVE A HISTORY OF OPERATING LOSSES, EXPECT TO CONTINUE TO INCUR LOSSES AND
RELY EXTENSIVELY ON EXTERNAL FINANCING TO MAINTAIN OUR OPERATIONS. IF WE ARE
UNABLE TO OBTAIN EXTERNAL FINANCING, WE WOULD BE REQUIRED TO FURTHER LIMIT,
SCALE BACK OR CEASE OUR OPERATIONS ENTIRELY.

     Since 1981, we have been engaged primarily in research and development and
have derived limited revenues from feasibility studies and the licensing of our
technology. We have not generated any material revenues from the sale of any
products. In addition, we have incurred net losses every year since we began
doing business and we anticipate that we will continue to incur losses for the
foreseeable future. As of December 31, 2005, we had an accumulated deficit of
approximately $82,584,992. For the fiscal years ended December 31, 2003, 2004
and 2005, we had a net loss of $5,661,694, $8,274,521, and $5,760,475,
respectively.

     On August 31, 2005, due to our financial condition at the time and our
inability to raise sufficient capital to maintain operations, we discontinued
all research and development activities and terminated substantially all of our
non-management personnel. In December 2005 and February 2006, we raised an
aggregate of $8.25 million in a private placement of our securities to
institutional investors. As a result of this private placement, we have begun to
resume operations with a focus on advancing clinical development of our lead
product, EcoNail. 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.

     Before we or any of our potential licensees may market any of our product
candidates, significant additional development efforts and substantial testing
will be necessary. We will require substantial additional financing to fund
clinical studies on our product candidates. We may not be able to secure
financing on favorable terms or at all. If we are unable to obtain external
financing, we would have to reduce, delay or eliminate our clinical studies.


                                       17


OUR PRODUCT CANDIDATES ARE IN THE EARLY STAGES OF DEVELOPMENT AND ARE SUBJECT TO
THE RISK OF FAILURE INHERENT IN THE DEVELOPMENT OF INNOVATIVE TECHNOLOGIES.

     Various pharmaceutical companies have developed systems to enhance the
topical delivery of specific drugs, but relatively limited research has been
conducted about using topical delivery systems for a wider range of
pharmaceutical products. Topical delivery systems currently are used only in a
limited number of products. In addition, some topical delivery systems have
demonstrated adverse side effects for users, including skin irritation and
delivery difficulties.

     Our product candidates are in the early stages of development and will
require significant further research, development, testing and regulatory
clearances. Our product candidates 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 our product candidates may be found
to be ineffective or toxic, or otherwise may fail to receive necessary
regulatory clearances.

OUR PRODUCT CANDIDATES MUST UNDERGO A RIGOROUS REGULATORY APPROVAL PROCESS,
WHICH INCLUDES EXTENSIVE PRE-CLINICAL AND CLINICAL TESTING, TO DEMONSTRATE
SAFETY AND EFFICACY BEFORE WE CAN MARKET THEM. IF THE RESULTS OF OUR
PRE-CLINICAL AND CLINICAL TESTING INDICATE THAT OUR PRODUCT CANDIDATES ARE NOT
SAFE OR EFFECTIVE, OUR BUSINESS WILL SUFFER.

     Each of our product candidates, including EcoNail and Opterone, must
undergo a rigorous regulatory approval process, including significant
pre-clinical and clinical testing to demonstrate that they are safe and
effective for human use, before we can market them. Conducting clinical trials
is a lengthy, expensive and uncertain process. Completion of clinical trials may
take several years or more. In addition, our clinical trials may be delayed by
many factors, including:

      o  inability to fund clinical trials;

      o  slow or insufficient patient enrollment;

      o  failure of the FDA to approve our clinical trial protocols;

      o  inability to manufacture significant amounts of our product candidates
         for use in a trial;

      o  safety issues; and

      o  government or regulatory delays.

     In addition, the results of pre-clinical studies and early clinical trials
may not accurately predict results that we will obtain in later testing. 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, the FDA or physicians do not believe
that our clinical trials demonstrate that our product candidates are safe and
effective, our business, financial condition and results of operations will be
materially adversely affected.


                                       18


OUR PRODUCT CANDIDATES ARE SUBJECT TO SIGNIFICANT FDA SUPERVISION AND MAY NOT
SUCCESSFULLY COMPLETE THE EXTENSIVE REGULATORY APPROVAL PROCESS REQUIRED PRIOR
TO THE MARKETING OF ANY PHARMACEUTICAL 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. Before
obtaining regulatory approval to market any product candidate under development,
we must demonstrate to the FDA that the product is safe and effective for use in
each proposed indication through, among other things, pre-clinical studies and
clinical trials. Data obtained from testing is subject to varying
interpretations which can delay, limit or prevent FDA approval.

     On October 11, 2002, the FDA advised us that further clinical trials of our
drugs containing SEPA had been placed on clinical hold pending review of
questions surrounding a 26-week transgenic-mouse (Tg.AC) carcinogenicity study
of SEPA we performed in 1999. On April 10, 2003, the FDA lifted this clinical
hold. In releasing the hold, the FDA requested additional information on that
1999 study, which we have provided.

     On December 5, 2005, we received a response from the Division of
Reproductive and Urologic Products at the FDA to questions posed by us regarding
the proposed Phase 3 clinical program for Opterone, a topical cream for male
testosterone deficiency containing our patented enhancer SEPA. In the response,
the FDA reiterated its safety concerns regarding the skin irritation potential
of SEPA related to pre-clinical studies of SEPA, including without limitation,
the 26-week transgenic-mouse (Tg.AC) carcinogenicity study of SEPA. The FDA also
expressed concern regarding skin irritation observed in some patients in
recently completed Opterone clinical studies. To address these concerns as well
as other issues related to Opterone's safety and efficacy program, the FDA
requested that we, if we intend to pursue clinical development of Opterone,
conduct additional investigation into multiple dose safety and pharmacokinetics
before beginning any eventual Phase 3 study. The FDA also confirmed the
requirement for other clinical pharmacology studies prior to any NDA submission
and requested that we revise our proposed Phase 3 protocol to include additional
patients and to extend patient exposure and safety follow-up. If we decide to
pursue the clinical development of Opterone, the additional investigation and
Phase 3 revisions will increase the time and expense associated with the
development of Opterone and may materially adversely affect our ability to find
a partner to advance the development of Opterone. Furthermore, there can be no
assurance that the results of the studies, if conducted, will address the FDA's
safety concerns or justify further development of Opterone or that any
SEPA-based product will be approved by the FDA.

     To date, neither the FDA nor any of its international equivalents has
approved any of our technologies or product candidates for marketing. If the FDA
does not approve our product candidates for marketing, we will be materially
adversely affected.

     We face additional risks associated with the regulatory approval process,
including:

      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. In addition, how these


                                       19


         rules actually operate can depend heavily on administrative policies
         and interpretations over which we have no control. We also may lack the
         experience with these policies and interpretations 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.

      o  The FDA review process may prevent us from marketing our product
         candidates or may involve delays that significantly and negatively
         affect our product candidates. We also 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 by the FDA. Any discovery of previously unrecognized problems
         with a product or a manufacturer could result in suspension or
         limitation of previously obtained or new approvals.

BECAUSE THE REGULATORY APPROVAL PROCESS IS COMPLEX, WE CANNOT ACCURATELY PREDICT
THE REGULATORY APPROVAL TIMELINE FOR OUR PRODUCT CANDIDATES.

     The laws and regulations administered by the FDA are complex, and
compliance with these laws and regulations requires substantial time, effort and
expense. Because of this complexity, and because the regulatory approval path
for our product candidates has not yet been confirmed by the FDA, we cannot
guarantee that our efforts will be sufficient to ensure compliance with all
applicable laws and regulations, nor can we accurately predict the regulatory
approval timeline for our product candidates.

IF OUR PRODUCT CANDIDATES ARE NOT ACCEPTED BY PHYSICIANS AND PATIENTS, WE MAY
NEVER BE PROFITABLE.

     Even if our product candidates receive regulatory approval, we may not be
able to market them effectively, they may be uneconomical to market or third
parties may market equivalent or superior products. We will need to expend
significant effort to educate physicians and patients regarding any product
candidate that receives regulatory approval. Consequently, unless our product
candidates obtain market acceptance, we may never be profitable.

IF PHYSICIANS OR PATIENTS PERCEIVE THAT TESTOSTERONE REPLACEMENT THERAPIES
CREATE HEALTH RISKS, THE VIABILITY OF OPTERONE MAY BE QUESTIONED, AND OUR
BUSINESS AND THE PRICE OF OUR STOCK MAY BE NEGATIVELY AFFECTED.

     Recent studies of female hormone replacement therapy products have reported
an associated increase in health risks. As a result of these studies, some
companies that sell or develop female hormone replacement products have
experienced decreased sales of these products, and in some cases, a decline in
their stock. From time to time, publications have suggested potential health
risks associated with testosterone replacement therapy, including fluid
retention, sleep apnea, breast tenderness or enlargement, increased red blood


                                       20


cells, development of clinical prostate disease, increased cardiovascular
disease risk and the suppression of sperm production. It is possible that
studies on the effect of testosterone replacement therapy could demonstrate
these or other adverse health risks. This, along with the negative publicity
surrounding hormone replacement therapy in general, could negatively impact
market acceptance of Opterone, which could adversely affect our business and the
price of our stock.

WE DEPEND ON PATENTS TO PROTECT OUR TECHNOLOGIES AND IF OUR CURRENT PATENTS ARE
INEFFECTIVE OR WE ARE UNABLE TO SECURE AND MAINTAIN ADEQUATE PATENT PROTECTION,
OUR ABILITY TO COMPETE WITH OTHER PHARMACEUTICAL COMPANIES MAY BE NEGATIVELY
AFFECTED.

     We believe that patent protection of our technologies, processes and
products is important to our future operations. The success of our product
candidates depends, in part, on our ability to secure and maintain adequate
patent protection.

     Although we have filed and intend to file additional patent applications,
the patent application process is lengthy and expensive and there is no
guarantee that a patent will be issued or, if issued, that it will be of
commercial benefit to us. In addition, it is impossible to anticipate the
breadth or degree of protection that any patents we obtain may afford us.
Further, products that we develop could infringe patents held by third parties.
In these cases, we may have to obtain licenses from third parties, which may not
be available on commercially acceptable terms, if at all. We do not maintain
separate insurance to cover intellectual property infringement.

     Our composition of matter patent covering SEPA expires in November 2006.
The expiration of that patent will enable competitors to develop SEPA-based
product candidates covering applications for which we have not obtained
composition and use patents. As a result, our competitive position may be
adversely affected.

     Currently, we are not involved in any litigation, settlement negotiations
or other legal action regarding patent issues and are not aware of any patent
litigation threatened against us. We may, however, become involved in patent
litigation against third parties to enforce our patent rights, to invalidate
patents held by those third parties or to defend against claims of those third
parties. We intend to enforce our patent position and defend our intellectual
property rights vigorously. The cost to us of any patent litigation or similar
proceeding could be substantial and it may absorb significant management time.
In the event of an unfavorable resolution of any infringement litigation against
us, we may be enjoined from manufacturing or selling any products without a
license from a third party.

IF WE ARE NOT ABLE TO PROTECT THE CONFIDENTIALITY OF OUR PROPRIETARY INFORMATION
AND KNOW-HOW, THE VALUE OF OUR TECHNOLOGIES MAY BE ADVERSELY AFFECTED.

     In addition to patent protection, we utilize significant unpatented
proprietary technology and rely on unpatented trade secrets and proprietary
know-how to protect certain aspects of our technologies. 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
technologies 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 our proprietary technologies.

                                       21


IF WE ARE NOT ABLE TO RETAIN OUR KEY PERSONNEL AND/OR RECRUIT ADDITIONAL KEY
PERSONNEL IN THE FUTURE, OUR BUSINESS MAY SUFFER.

     The success of our business depends on our ability to attract, retain and
motivate qualified senior management personnel and qualified scientific
personnel. We consider Robert J. DeLuccia, our President and Chief Executive
Officer, to be a key employee and we have entered into an employment agreement
with him. We do not maintain key person life insurance on any of our employees.
In our industry, the competition for experienced personnel is intense and can be
expected to increase. From time to time we may face, and in the past have faced,
difficulties in attracting and retaining employees with the requisite experience
and qualifications. If we fail to retain or attract this type of personnel, it
could have a significant negative effect on our ability to develop our
technologies.

OUR FAILURE TO IDENTIFY PHARMACEUTICALS THAT ARE COMPATIBLE WITH OUR DRUG
DELIVERY TECHNOLOGIES OR ADDITIONAL PRODUCT CANDIDATES OR TECHNOLOGIES WOULD
IMPAIR OUR ABILITY TO GROW.

     Our growth depends on our ability to identify drugs suitable for delivery
using our proprietary drug delivery technologies, our ability to identify other
product candidates or technologies, and our ability, financially or otherwise,
to obtain such product candidates and technologies. Identifying suitable drugs
or product candidates is a lengthy and complex process. Even if identified, the
drugs or product candidates may not be available to us or we may otherwise be
unable to enter into licenses or other agreements for their use. Other
companies, including those with substantially greater financial, marketing and
sales resources, may compete with us for the licensing or acquisition of drugs
and product candidates and we may not be able to enter into licenses or other
agreements on acceptable terms, or at all. If we are unable to identify and
license or acquire drugs that are compatible with our drug delivery technologies
or additional product candidates or technologies, our ability to grow our
portfolio of product candidates and our prospects would be adversely affected.

WE DO NOT HAVE ANY LABORATORY FACILITIES OR SCIENTIFIC PERSONNEL AND DEPEND ON
THIRD PARTIES TO CONDUCT RESEARCH AND DEVELOPMENT ACTIVITIES FOR OUR
TECHNOLOGIES AND PRODUCT CANDIDATES.

     We do not have laboratory facilities or scientific personnel capable of
conducting research and development activities for our technologies and product
candidates and currently we do not have plans to obtain such facilities and
personnel. Accordingly, our ability to conduct research and development
activities is and will be limited and we will depend to a significant extent on
third-party contractors for such research and development activities. If any of
our third-party contractors fails to perform its obligations in a timely fashion
or in accordance with applicable regulations, it may adversely affect our
business. If we decide to establish internal research and development
capabilities, we would need to hire and retain significant additional personnel,
locate and acquire appropriate laboratory facilities, comply with extensive
government regulations, and obtain additional capital, which may not be
available on acceptable terms, or at all.

                                       22


WE DO NOT HAVE ANY MANUFACTURING FACILITIES AND DEPEND ON THIRD PARTIES TO
MANUFACTURE OUR PRODUCT CANDIDATES.

     We do not have facilities capable of manufacturing any of our product
candidates and we do not have plans to obtain these facilities. Accordingly, we
will depend on third-party contractors, licensees, or corporate partners to
manufacture our products. If any of our third-party manufacturers fails to
perform its obligations in a timely fashion or in accordance with applicable
regulations, it may delay clinical trials, the commercialization of our product
candidates or our ability to supply our product candidates for sale. If we
decide to establish a commercial manufacturing facility, we would need to hire
and retain significant additional personnel, comply with extensive government
regulations, and obtain significant amounts of additional capital, which may not
be available on acceptable terms, or at all.

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 product candidates
involve risk of liability claims and associated adverse publicity. We have
product liability insurance coverage with an aggregate policy limit of
approximately $10,000,000 for claims related to our product candidates that may
arise from clinical trials conducted prior to November 1, 2002. We also have
product liability insurance coverage with aggregate policy limits between
approximately $3,000,000 and $5,000,000 for claims related to our product
candidates that may arise from clinical trials conducted after September 25,
2003. In the event that our products receive regulatory approval and become
commercialized, we would need to acquire additional coverage. Product liability
insurance is expensive, may be difficult to obtain and may not be available on
acceptable terms, if at all. If we obtain coverage, we cannot guarantee that the
coverage limits of these insurance policies will be adequate. A successful claim
against us if we are uninsured, or which is in excess of our insurance coverage,
could have a material adverse effect on us and our financial condition.

WE RELY ON A THIRD-PARTY SUPPLIER FOR A NON-ACTIVE INGREDIENT IN SOME OF OUR
PRODUCT CANDIDATES AND, IN THE EVENT THE SUPPLIER IS UNABLE TO SUPPLY US WITH
ADEQUATE PRODUCT, OUR BUSINESS MAY BE NEGATIVELY AFFECTED IF WE ARE NOT ABLE TO
TIMELY OBTAIN A SUBSTITUTE INGREDIENT.

     We rely on a third-party supplier, Seppic Inc., for a non-active ingredient
that is important to the formulation and production of some of our topical
product candidates. While we believe similar products are available from other
suppliers, if Seppic Inc. were unable or unwilling to supply its product in
sufficient quantities at a reasonable price, our results could suffer, as we may
encounter significant costs and delays in identifying and measuring the efficacy
of replacement third party products.

                                       23


TOGETHER, CERTAIN OF OUR SHAREHOLDERS OWN A MAJORITY OF OUR STOCK AND COULD
ULTIMATELY CONTROL DECISIONS REGARDING US.

     In our recent private placement, we issued 825.5 shares of our Series C
Cumulative Convertible Preferred Stock and warrants to purchase 7,861,912 shares
of our common stock. The Series C Cumulative Convertible Preferred Stock is
convertible into shares of common stock and votes together with the common stock
on an as-if-converted to common stock basis. Unless a holder of Series C
Cumulative Convertible Preferred Stock elects otherwise, its ability to convert
its Series C Cumulative Convertible Preferred Stock into common stock or to vote
on an as-if-converted to common stock basis is restricted to the extent that
such conversion would result in the holder owning more than 4.95% of our issued
and outstanding common stock or voting together with the common stock on an
as-if-converted to common stock basis in respect of more than 4.95% of our
issued and outstanding common stock. The warrants issued in the private
placement are subject to a similar restriction on their exercise. SCO Capital
Partners LLC, Beach Capital LLC and Perceptive Life Sciences Master Fund Ltd.
("Perceptive") have elected not to be governed by these restrictions, although
we have entered into an agreement with Perceptive whereby Perceptive's ability
to convert or vote their shares of Series C Preferred Stock will be subject to a
beneficial ownership cap of 9.95% instead of 4.95%. Consequently, giving effect
to the beneficial ownership cap restrictions, the Series C Preferred Stock
acquired by the investors is convertible into 4,057,882 shares of common stock
and the holders of the Series C Cumulative Convertible Preferred Stock vote on
an as-converted basis with the holders of our common stock, and therefore hold
approximately 80.28% of the voting power of our outstanding securities. Assuming
both the conversion of the Series C Cumulative Convertible Preferred Stock and
the exercise of all of the Warrants acquired by the investors, in each case
without regard to the beneficial ownership cap restrictions, the investors would
hold approximately 94% of the outstanding common stock of the Company. In
addition, for so long as 20% of the Series C Cumulative Convertible Preferred
Stock issued in the private placement remains outstanding, SCO Capital Partners
LLC has the right to designate two members to our board of directors. Jeffrey B.
Davis and Howard S. Fischer are currently serving on our board of directors as
the designees of SCO Capital Partners LLC

     Because of the voting rights of the Series C Cumulative Convertible
Preferred Stock and the fact that the parties described above currently own a
large portion of our voting stock, they may be able to generally determine or
they will be able to significantly influence the outcome of corporate actions
requiring shareholder approval. As a result, these parties may be in a position
to control matters affecting our company, including amendments to our articles
of incorporation and bylaws; payment of dividends on our common stock; and
acquisitions, sales of all or substantially all of our assets, mergers or
similar transactions, including transactions involving a change of control. As a
result, some investors may be unwilling to purchase our common stock. In
addition, if the demand for our common stock is reduced because of these
shareholders' control of the Company, the price of our common stock could be
materially depressed.

                                       24


CERTAIN OF OUR SHAREHOLDERS OWN LARGE BLOCKS OF OUR COMMON STOCK AND OWN
SECURITIES CONVERTIBLE OR EXERCISABLE INTO SHARES OF OUR COMMON STOCK, AND ANY
EXERCISES, CONVERSIONS OR SALES BY THESE SHAREHOLDERS COULD SUBSTANTIALLY LOWER
THE MARKET PRICE OF OUR COMMON STOCK.

     Several of our shareholders, including those shareholders that acquired
Series C Cumulative Convertible Preferred Stock and warrants to acquire common
stock in our recent private placement, own large blocks of our voting stock. The
shares of our common stock owned by these shareholders (or issuable to them upon
exercise or conversion of warrants or Series C Cumulative Convertible Preferred
Stock) will be registered. Future sales of large blocks of our common stock by
any of the above investors could substantially depress our stock price.

                          RISKS RELATED TO OUR INDUSTRY
                          -----------------------------

OUR INDUSTRY IS HIGHLY COMPETITIVE AND OUR COMPETITORS HAVE OR MAY HAVE
SIGNIFICANTLY MORE RESOURCES THAN WE HAVE.

     We compete with a number of 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 Bentley
Pharmaceuticals, Inc., Biosante Pharmaceuticals, Inc., NexMed, Inc., ALZA
Corporation, Connetics Corporation, Antares Pharma, Inc. and Barrier
Therapeutics, Inc. Competitors with approved products in the therapeutic areas
that our clinical stage product candidates seek to address include, with respect
to onychomycosis:

      o  Novartis AG, maker of Lamisil(R), an oral therapy;

      o  Johnson & Johnson, maker of Sporanox(R), an oral therapy; and

      o  Sanofi Aventis (Dermik Laboratories), maker of Penlac, a topical nail
         lacquer.

and with respect to male hypogonadism:

      o  Solvay Pharmaceuticals, Inc., maker of Androgel(R), a topical gel
         therapy;

      o  Auxilium Pharmaceuticals, Inc., maker of Testim(R), a topical gel
         therapy;

      o  Watson Pharmaceuticals, Inc., maker of Androderm(R), a transdermal
         patch; and

      o  Columbia Laboratories, Inc., maker of Striant(R), a buccal film which
         is placed between the patient's cheek and gum;

     These companies have or may have substantially greater capital resources,
research and development and technical staff, facilities and experience in
obtaining regulatory approvals, as well as in manufacturing, marketing and
distributing products, than we do. Recent trends in this industry 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 also are 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


                                       25


be the basis for competitive products which may be more effective or less costly
to use than any products that we currently are developing.

     We expect any future products approved for sale to compete primarily on the
basis of product 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 commercial advantage
compared with later entrants to the market. Our competitive position also will
depend on our ability to resume research and development activities, engage
third parties to conduct research and development activities, 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.

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

     The future revenues and profitability of, and availability of capital for,
biomedical and pharmaceutical companies may be affected by the continuing
efforts of governmental and private third-party payers to contain or reduce the
costs of health care through various means. Reimbursement by payors such as
government and managed care organizations has become an increasingly important
factor in the success of a drug, as has the listing of new products on large
formulary lists (as well as their designated "Tier" on such lists), including
those of managed care organizations, pharmaceutical benefit providers and group
buying organizations. Failure of a pharmaceutical product to be included on
formulary lists, to obtain a Tier position on such formulary lists which
provides for a sufficiently low patient cost, or to be reimbursed by government
or managed care organizations, could negatively impact the profitability of a
drug.

     Furthermore, in some foreign markets pricing or profitability of
prescription pharmaceuticals is subject to government control and to possible
reform in the health care system. Frequently, it is not possible to obtain
pricing in foreign markets that is as favorable as that obtainable in the U.S.
In the U.S., there have been, and we expect there will continue to be, a number
of federal and state proposals to impose similar governmental control. While we
cannot predict whether any of these legislative or regulatory proposals will be
adopted, the announcement or adoption of these proposals could have a material
adverse effect on our prospects.

     If we succeed in bringing to market one or more of our product candidates,
we cannot assure you that these product candidates will be cost effective or
that reimbursement to the consumer will be available or will be sufficient to
allow us to sell these products on a profitable basis.

                     RISKS RELATED TO THE SECURITIES MARKET
                     --------------------------------------

OUR STOCK PRICE HAS BEEN, AND LIKELY WILL CONTINUE TO BE, HIGHLY VOLATILE, AND
AS A RESULT, AN INVESTMENT IN OUR STOCK IS SUBJECT TO SUBSTANTIAL RISK.

     The market price of our stock has been, and will likely continue to be,
highly volatile due to the risks and uncertainties described in this section of
this document, as well as other factors, including:

      o  the discontinuance in August 2005 of all of our research and product
         development activities and our dependence on additional external
         funding in resuming such activities;

      o  the results of our previously conducted clinical trials for our
         SEPA-based formulations;

      o  conditions and publicity regarding the pharmaceutical industry
         generally as well as the specific therapeutic areas our product
         candidates seek to address;

      o  price and volume fluctuations in the stock market at large which do not
         relate to our operating performance; and

      o  our ability to raise additional capital.

     Over the two-year period ending December 31, 2005, the closing price of our
common stock as reported on The Nasdaq National Market, The Nasdaq Capital
Market, the Pink Sheets LLC and the OTC Bulletin Board ranged from a high of
$75.18 to a low of $1.26. On March 7, 2006, the closing price for our common
stock on the OTC Bulletin Board was $1.66. In the past, companies that have
experienced stock price volatility have sometimes been the subject of securities
class action litigation. If litigation were instituted on this basis, it could
result in substantial costs and a diversion of management's attention and
resources. As a result of this volatility, an investment in our stock is subject
to substantial risk.

ON NOVEMBER 22, 2005, OUR COMMON STOCK WAS DELISTED FROM THE NASDAQ CAPITAL
MARKET FOR FAILURE TO MEET ITS LISTING STANDARDS. OUR COMMON STOCK CURRENTLY IS
QUOTED ON THE OTC BULLETIN BOARD, WHICH INVESTORS MAY PERCEIVE AS LESS DESIRABLE
AND WHICH COULD NEGATIVELY AFFECT THE LIQUIDITY OF AN INVESTMENT IN OUR COMMON
STOCK.

     Our listing on The Nasdaq Capital Market was conditioned on our compliance
with Nasdaq's continued listing requirements. The minimum standards for
continued listing on The Nasdaq Capital Market include stockholders' equity of
$2.5 million or market capitalization of $35 million and a minimum bid price of
$1.00.

     On October 18, 2005, we received a Nasdaq Staff Determination indicating
that our securities were subject to delisting from The Nasdaq Capital Market as
we did not comply with the minimum bid price requirement for continued listing.
We requested a hearing before a Nasdaq Listing Qualifications Panel to review
the Staff Determination. On November 21, 2005, we withdrew our appeal of the
Nasdaq Staff Determination and our common stock was delisted from quotation on
the Nasdaq Capital Market effective as of Tuesday, November 22, 2005.


                                       27


Immediately thereafter, our common stock was quoted on the Pink Sheets LLC, and
on December 22, 2005, our stock became eligible for quotation on the OTC
Bulletin Board and presently trades under the symbol "MACM.OB."

     The over-the-counter market is generally considered to be a less efficient
system than markets such as Nasdaq or other national exchanges because of lower
trading volumes, transaction delays and reduced security analyst and news media
coverage. These factors could contribute to lower prices and larger spreads in
the bid and ask prices for our common stock. Additionally, trading of our common
stock in an over-the-counter market may make us less desirable to institutional
investors and may, therefore, limit our future equity funding options.

WE ARE CONTRACTUALLY OBLIGATED TO ISSUE SHARES IN THE FUTURE, DILUTING YOUR
INTEREST IN US.

     As of March 7, 2006, our Series C Cumulative Convertible Preferred Stock is
convertible into an aggregate of, giving effect to the beneficial ownership
restrictions on conversion, 4,057,882 shares of common stock (7,861,900 shares
of common stock without regard to the beneficial ownership restrictions on
conversion). In addition, as of March 7, 2006, there are outstanding and
exercisable warrants to purchase approximately 8,725,270 shares of our common
stock, at a weighted average exercise price of $1.89 per share. As of March 7,
2006, there also are outstanding and exercisable options to purchase
approximately 430,264 shares of our common stock, at a weighted average exercise
price of $34.06 per share. Moreover, we expect to issue additional options to
purchase shares of our common stock to compensate employees, consultants and
directors and may issue additional shares to raise capital, acquire other
companies or technologies, to pay for services, or for other corporate purposes.
Any such issuances will have the effect of further diluting the interest of the
purchasers of the securities being sold in this offering.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

     Not applicable.

ITEM 2.  PROPERTIES.

     We currently occupy approximately 3,000 square feet of office and
laboratory space under a month-to-month sublease. 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 requirements, and we are
evaluating our future facility requirements. We also believe that suitable
alternative locations are readily available.

ITEM 3.  LEGAL PROCEEDINGS.

     We are not currently engaged in any material legal proceedings.

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

     As described in our Current Report on Form 8-K filed on February 15, 2006,
an amendment to the Company's certificate of incorporation to effect a 1-for-6
reverse stock split of our common stock was approved on December 23, 2005 by


                                       28


written consent of our stockholders holding a majority of the shares entitled to
vote on the matter. Additional information regarding the reverse stock split is
contained in our Information Statement filed with the Securities and Exchange
Commission on January 17, 2006.

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

     YOU SHOULD READ THE FOLLOWING DISCUSSION IN CONJUNCTION WITH OUR FINANCIAL
STATEMENTS AND RELATED NOTES AND OTHER FINANCIAL INFORMATION APPEARING ELSEWHERE
IN THIS ANNUAL REPORT ON FORM 10-K. IN ADDITION TO HISTORICAL INFORMATION, THE
FOLLOWING DISCUSSION AND OTHER PARTS OF THIS ANNUAL REPORT ON FORM 10-K CONTAIN
FORWARD-LOOKING INFORMATION THAT INVOLVES RISKS AND UNCERTAINTIES. OUR ACTUAL
RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED BY SUCH FORWARD-LOOKING
INFORMATION DUE TO THE FACTORS DISCUSSED UNDER "RISK FACTORS," "NOTE REGARDING
FORWARD-LOOKING STATEMENTS" AND ELSEWHERE IN THIS ANNUAL REPORT ON FORM 10-K.

GENERAL

     We are a specialty pharmaceutical company that develops and seeks to
commercialize pharmaceutical products. Currently, our portfolio of product
candidates is based on our proprietary drug delivery technologies: SEPA,
MacroDerm and DermaPass. Our patented SEPA topical drug delivery technology
(SEPA is an acronym for "Soft Enhancement of Percutaneous Absorption," where
"soft" refers to the reversibility of the skin effect, and "percutaneous" means
"through the skin") enhances the efficiency and rate of diffusion of drugs into
and through the skin. Our patented MacroDerm drug delivery technology
encompasses a family of low to moderate molecular weight polymers that impede
dermal drug or chemical penetration. We have also filed a patent application for
our DermaPass family of transdermal absorption enhancers that have a different
drug delivery profile than SEPA, which we believe could be used with a wider
range of active pharmaceutical ingredients. Currently, we have two clinical
stage investigational new drugs: EcoNail, our lead product, for the treatment of
fungal infections of the nails and Opterone, for the treatment of male
hypogonadism. We believe that products incorporating our drug delivery
technologies may allow selected drugs to be administered more effectively and
with improved patient compliance compared to alternative methods of drug
administration, such as ingestion and injection.

     Since inception, we have been engaged primarily in research and
development. We have not generated any meaningful revenues from operations and
we have sustained significant operating losses. We anticipate that we will
continue to incur significant losses for the foreseeable future. We cannot
guarantee that we will be successful in commercializing our products, or that we
will ever become profitable. As of December 31, 2005, we had an accumulated
deficit of approximately $82,584,992. Our product candidates are in discovery or
developmental stages and must undergo a rigorous regulatory approval process,
which includes costly and extensive pre-clinical and clinical testing, to
demonstrate safety and efficacy before we can market any resulting product. To
date, neither the FDA nor any of its international equivalents has approved any
of our product candidates for marketing. Please see our financial statements
included elsewhere in this Annual Report on Form 10-K for a more detailed
description of our financial history.

     Our results of operations can vary significantly from year to year and
quarter to quarter, and depend, among other factors, on:

      o  the progress of clinical trials we conduct;


                                       32


      o  the degree of our research, marketing and administrative efforts;

      o  our ability to raise additional capital;

      o  the signing of licenses and product development agreements;

      o  the timing of revenues recognized pursuant to license agreements; and

      o  the achievement of milestones by licensees.

     The timing of our revenues may not match the timing of our associated
product development expenses. To date, our research and development expenses
generally have exceeded our revenues in any particular period or fiscal year.

     We expect to continue to spend significant amounts on developing and
seeking regulatory approval of our lead product, EcoNail. Ultimately, if we
receive regulatory approval for EcoNail, significant expenses will be incurred
in connection with its commercialization. In addition, we also plan to identify
and develop, internally, through in-licensing, or through other collaborative
arrangements, additional product candidates and technologies that fit within our
growth strategy. If we identify potential product candidates, we will incur
additional costs in connection with testing and seeking regulatory approval of
those product candidates.

     We recently completed a private placement of our securities to
institutional investors, consisting of two closings, for approximately
$8,255,000 in gross proceeds. The first closing of the private placement, in
which institutional investors acquired 250 shares of Series C Cumulative
Convertible Preferred Stock (the "Series C Preferred Stock") and six-year
warrants to purchase 2,380,951 shares of common stock at an exercise of $1.26
per share, for an aggregate purchase price of $2,500,000, took place on December
23, 2005 and is described in our Current Report on Form 8-K filed on December
27, 2005. The second closing of the private placement, in which institutional
investors acquired 575.5 shares of our Series C Preferred Stock and six-year
warrants to purchase 5,480,961 shares of the Company's common stock at an
exercise price of $1.26 per share, for an aggregate purchase price of
$5,755,000, occurred on February 13, 2006 and is described in our Current Report
on Form 8-K filed on February 16, 2006. The Series C Preferred Stock has a
liquidation value of $10,000 per share, is entitled to a dividend of 10% per
annum, payable in cash or shares of our common stock at our option, which
dividend rate is subject to increase to 14% upon the occurrence of certain
events. The number of shares of common stock into which each share of Series C
Preferred Stock is convertible is determined by dividing the liquidation value
per share plus all accrued and unpaid dividends thereon by $1.05. The conversion
price for the Series C Preferred Stock and the warrant exercise price are each
subject to a reset adjustment such that if the average of the price of the
common stock over the twenty trading days immediately preceding May 8, 2006 (the
"Average Price") is lower than the conversion and/or exercise price, then such
conversion and/or exercise price shall be adjusted to equal the Average Price.

                                       33


     We believe that our existing cash and cash equivalents of $3,023,436 as of
December 31, 2005 will be sufficient to meet our operating expenses and capital
expenditure requirements for at least the next twelve months. As noted above, on
February 13, 2006 we received $5,755,000 in gross proceeds ($5,265,100 net of
issuance costs but before legal and accounting costs) from the sale of our
Series C Preferred Stock and warrants to purchase shares of our common stock. We
intend to use these proceeds for working capital and other general corporate
purposes.

     RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
consist of:

      o  salaries and expenses for our research and development personnel;

      o  payments to consultants, investigators, contract research organizations
         and manufacturers in connection with our pre-clinical and clinical
         trials;

      o  costs associated with conducting our clinical trials;

      o  costs of developing and obtaining regulatory approvals; and

      o  allocable costs, including occupancy and depreciation.

     Because a significant portion of our research and development expenses
(including employee payroll and related benefits, laboratory supplies, travel,
dues and subscriptions, temporary help costs, consulting costs and allocable
costs such as occupancy and depreciation) benefit multiple projects or our drug
delivery technologies in general, we do not track these expenses by project. On
August 31, 2005, we discontinued all research and development activities and
terminated substantially all of our non-management personnel. For the fiscal
year ended December 31, 2005, we spent $2,291,721 on research and development,
including $22,965 and $111,739 in costs associated with clinical trials for
EcoNail and Opterone, respectively, and $2,157,017 in costs not specifically
tracked to a project. For the fiscal year ended December 31, 2004, we spent
$4,221,039 on research and development, including $469,515, $1,109,345 and
$388,360 in costs associated with our clinical trials for EcoNail, Opterone and
Topiglan (our topical formulation of SEPA and alprostadil for treatment of
erectile dysfunction), respectively, and $2,253,819 in costs not specifically
tracked to a project. For the fiscal year ended December 31, 2003, we spent
approximately $2,938,026 on research and development, including $1,584,000 in
costs associated with our clinical trial for Topiglan and $1,354,026 in costs
not specifically tracked to a project. EcoNail and Opterone were not in clinical
trials in 2003. Following a complete review of the results of a Phase 2
pharmacodynamic study of Topiglan in which Topiglan did not meet its primary
clinical endpoints, we have no plans for further clinical studies of Topiglan.
Accordingly, as of June 30, 2004, we recorded a reduction of $124,853 to the
carrying value of certain patent assets related to Topiglan. For the year ending
December 31, 2006, we expect to continue to spend significant amounts on
clinical trials for EcoNail.

     Each of our research and development programs is subject to risks and
uncertainties, including the requirement to seek regulatory approval, that are
outside of our control. Moreover, the product candidates identified in these
research and development programs, which currently are in developmental stages,
must overcome significant technological, manufacturing and marketing challenges


                                       34


before they can be successfully commercialized. As a result of these risks and
uncertainties, we are unable to predict with any certainty the period in which
material net cash inflows from these projects could be expected to commence or
the completion date of these programs. For example, we are seeking a partner to
advance development of our Opterone product candidate. We cannot predict whether
our efforts to find a partner will be successful nor can we predict the manner
and timing in which any eventual partner may elect to pursue development of
Opterone. In addition, these risks and uncertainties also prevent us from
estimating with any certainty the specific timing and future costs of our
clinical development programs, although historical trends at similarly situated
companies indicate that research and development expenses tend to increase in
later stages of clinical development. Our failure to obtain requisite
governmental approvals timely or at all will delay or preclude us from licensing
or marketing our products or limit the commercial use of our products, which
could adversely affect our business, financial condition and results of
operations.

     MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES. Marketing, general and
administrative expenses consist primarily of salaries and other related costs
for personnel, marketing and promotion, professional fees and facilities costs.
Assuming we are able to raise sufficient capital, we anticipate that marketing,
general and administrative expenses will increase over the next several years as
we begin, when appropriate, to license, partner, or market our product
candidates if and when they receive regulatory approval.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Our discussion and analysis of our financial condition and results of
operations are based on 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 us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
revenues and expenses. Note 1 to our financial statements included elsewhere in
this Annual Report on Form 10-K includes a summary of the significant accounting
policies and methods we use in the preparation of our financial statements. The
following is a brief discussion of the more significant accounting policies and
methods that affect the judgments and estimates used in the preparation of our
financial statements.

     RESEARCH AND DEVELOPMENT REVENUE. Generally, we recognize research and
development funding as revenue at the time the research and development
activities are performed under the terms of the related agreements, when the
counterparty is obligated to pay, and when no future performance obligation
exists. We make estimates of the status of performance with respect to research
and development contracts. In the past, we have found such estimates to be
sufficiently accurate for revenue recognition purposes. We bill research and
development revenue on a cost reimbursement basis, which includes direct costs
we incur in connection with research activities and an allocation of certain
other costs we incur.

     PATENT ASSETS. We defer costs and expenses incurred in connection with
pending patent applications. We amortize costs related to successful patent
applications over the estimated useful lives of the patents using the
straight-line method. We charge accumulated patent costs and deferred patent
application costs related to patents that are considered to have limited future
value to operations. Estimates we use to determine the future value of deferred
patent costs include analysis of potential market size, time and cost to


                                       35


complete clinical trials, anticipated interest in our products and potential
value for licensing or partnering opportunities. We recognize revenues derived
or expected to be derived from the sale, assignment, transfer, or licensing of
patents or other intellectual property based upon the terms of the relevant
agreement.

     DEFERRED TAXES. As part of the process of preparing our financial
statements we are required to estimate our income taxes in each of the
jurisdictions in which we operate. This process involves estimating our actual
current tax exposure together with assessing temporary differences resulting
from differing treatments of items for tax and accounting purposes. These
differences result in deferred tax assets and liabilities. In addition, as of
December 31, 2005, we had federal tax net operating loss carryforwards of
approximately $69,339,393, which expire through 2025. We also have research and
development credit carryforwards of $2,432,167. We have recorded a valuation
allowance to fully offset against these otherwise recognizable net deferred tax
assets due to the uncertainty surrounding the timing of the realization of the
tax benefit. In the event that we determine in the future that we will be able
to realize all or a portion of the net deferred tax benefit, an adjustment to
deferred tax valuation allowance would increase net income in the period in
which such a determination is made. The utilization of net operating loss
carryforwards and credits available to be used in any given year may be limited
in the event of significant changes in ownership interest, as defined.

RESULTS OF OPERATIONS
YEAR ENDED DECEMBER 31, 2005 COMPARED TO THE YEAR ENDED DECEMBER 31, 2004

     We had no revenues for the years ended December 31, 2005 and December 31,
2004. For the year ending December 31, 2006, we do not expect to have any
revenues.

     Research and development costs for 2005 decreased by $1,929,318, from
$4,221,039 in 2004 to $2,291,721 in 2005, a 45.7% decrease. The decrease is
primarily attributable to the cessation of research and development activities
in August 2005, including a reduction in spending on clinical trials of
$1,832,516 compared with 2004 and a reduction in payroll and related expenses of
$204,494 in 2005 as a result of a staff reduction in August 2005. The decrease
in research and development costs as a result of these reductions was offset in
part by increases in payments to technical consultants of $115,000 and other
miscellaneous research expenses. For the year ending December 31, 2006, we
expect to incur clinical trial costs of approximately $750,000.

     Marketing, general and administrative costs for 2005 decreased by
$1,170,360, from $4,158,452 in 2004 to $2,988,092 in 2005, a 28.0% decrease. The
decrease is primarily attributable to a staff reduction in August 2005 which
resulted in a reduction of salary and related expenses of $524,562. In addition,
in 2005 legal and audit expenses decreased by approximately $230,000, travel
expenses decreased by $40,000, insurance expenses decreased by $75,000,
consulting and investor relations expenses decreased by $320,000 and market
development expenses decreased by $110,000. The aggregate decrease in marketing,
general and administrative costs was offset, in part, by a payment of
approximately $370,000 to certain executive officers and administrative staff
under transition agreements. For the year ending December 31, 2006, we expect
marketing, general and administrative costs to approximate $2,200,000.

                                       36


     As reported on a Current Report on Form 8-K filed on September 7, 2005, the
Company terminated substantially all its non-management personnel on August 31,
2005. The costs associated with this staff reduction and related expenses were
approximately $156,839. As reported on a Current Report on Form 8-K filed on
September 16, 2005, the Company entered into transition agreements with its
executive officers in September 2005. The transition agreements terminated the
existing employment and severance agreements between the Company and each
executive. Pursuant to the terms of the transition agreements, the executives
agreed that they would remain employed by the Company until November 30, 2005.
Three executives executed amendments to their transition agreements extending
their employment through December 31, 2005 and beyond. The total costs
associated with all executive transition agreements were approximately $709,646.
Of this total, approximately $320,000 was charged to marketing, general and
administrative expenses. These agreements also provided for aggregate payments
of approximately $35,000 on November 30, 2005 and $35,000 on December 15, 2005.

     Total other income decreased by $39,421 or 37.5%, from $104,971 in 2004 to
$65,550 in 2005. The decrease is attributable to lower cash balances available
for investment purposes in 2005.

     For the year ended December 31, 2005, our net loss was $5,760,475 as
compared to a loss of $8,274,521 for the previous year, a 30.4% decrease, which
was due to the factors mentioned above.

YEAR ENDED DECEMBER 31, 2004 COMPARED TO THE YEAR ENDED DECEMBER 31, 2003

     We had no revenues for the year ended December 31, 2004. Revenues for the
year ended December 31, 2003 were $1,010,031, nearly all of which was
attributable to the proceeds from the sale of a patent (U.S. Patent No.
6,459,124), which related to antifungal topical compositions but which did not
use our SEPA platform technology. Accordingly, we believe the sale of the patent
will not materially adversely affect our future operations, cash flows and
financial position.

     Research and development costs increased by $1,283,013 from $2,938,026 in
2003 to $4,221,039 in 2004, a 44 % increase. The increase in research and
development costs for 2004 is primarily attributable to an increase in employee
compensation of $177,034 associated with the addition of four new research and
development employees in late 2003 as well as an increase in clinical trials and
related costs of $1,034,555. Of total research and development expenses,
$361,141 in 2004 and $494,909 in 2003 were paid to independent third party
contractors.

     Marketing, general and administrative expenses for 2004 aggregated
$4,158,452, an increase of $360,360 or 9%, from 2003's total of $3,798,092. The
increase in marketing, general and administrative expenses for 2004 is primarily
attributable to an increase of $239,942 (which increase was calculated by
excluding $55,000 in consulting fees paid to Robert J. DeLuccia in his role as
interim Chief Executive Officer during the six months ended June 30, 2003) in
consulting fees relating to investor relations and business development, and an
increase in accounting related fees of $129,700. The increase is further
attributable to the reduction to the carrying value of certain patent assets
related to Topiglan of $124,853. Finally, the aggregate size of the increase in

                                       37

marketing, general and administrative expenses for 2004 was partially offset by
savings in recruitment costs as well as a reduction in the premium for Directors
and Officers Insurance.

     Total other income increased by $34,578 or 49%, from $70,393 in 2003 to
$104,971 in 2004. The increase is attributable primarily to higher cash balances
available for investment purposes.

     For the year ended December 31, 2004, our net loss was $8,274,521 as
compared to a loss of $5,661,694 for the previous year, a 46% increase, which
was due to the factors mentioned above.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception, our primary source of funding for our operations has been
the private and public sale of our securities, and, to a lesser extent, the
licensing of our proprietary technology and products, research collaborations,
feasibility studies, government grants and the limited sales of products and
test materials. During 2003, we received net proceeds of $99,575 from the
exercise of stock options and warrants, and net proceeds of $2,971,605 as a
result of the sale of our common stock in a private placement. During 2004, we
received net proceeds of $443,817 from the exercise of warrants, and proceeds of
$6,681,275 (net of issuance costs) as a result of the sale of our common stock
in a private placement financing transaction. During 2005, we received net
proceeds of $87,500 from the exercise of warrants, and proceeds of $815,000
($601,342 net of issuance costs) as a result of the sale of our common stock and
proceeds of $2,500,000 ($2,125,943 net of issuance costs) as a result of the
sale of our Series C Cumulative Convertible Preferred Stock in private placement
financing transactions. On February 13, 2006, we received gross proceeds of
$5,755,000 ($5,265,100 net of issuance costs but before legal and accounting) as
a result of the sale of our Series C Cumulative Convertible Preferred Stock in a
private placement financing transaction.

     At December 31, 2005, working capital was approximately $2.7 million,
compared to $5.6 million at December 31, 2004. The decrease in our working
capital reflects the use of funds in operations, partially offset by the receipt
of private placement proceeds and net proceeds from the exercise of warrants. On
March 9, 2004, we sold approximately 128,619 shares of our common stock for
$7,292,700 in gross proceeds ($6,681,275 net of issuance costs) in a private
placement to institutional investors. The investors also received warrants to
purchase approximately 25,717 shares of common stock at a purchase price of
$87.78 per share expiring five years from the closing date. On April 19, 2005,
we sold approximately 65,040 shares of our common stock to institutional
investors and to certain executive officers and directors of the Company for
$815,000 in gross proceeds ($601,342 net of issuance costs). The investors also
received warrants to purchase approximately 32,520 shares of common stock at
exercise prices $14.70 for the institutional investors and $21.84 for the
officers and directors. On December 23, 2005, we sold 250 shares of Series C
Cumulative Convertible Preferred Stock for $2,500,000 in gross proceeds
($2,125,943 net of issuance costs) in a private placement to institutional
investors. The investors also received warrants to purchase 2,380,951 shares of
common stock at an exercise of $1.26 per share. On February 13, 2006, we sold
575.5 shares of our Series C Cumulative Convertible Preferred Stock for
$5,755,000 in gross proceeds ($5,265,100 net of issuance costs but before legal


                                       38


and accounting) in a private placement to institutional investors. The investors
also received warrants to purchase 5,480,961 shares of the Company's common
stock at an exercise price of $1.26 per share. Until such time as we obtain
agreements with third-party licensees or partners to provide funding for our
anticipated business activities, or otherwise generate revenue from the
commercialization of our products, we will use our working capital to fund our
operating activities.

     Pursuant to a plan approved by our Board of Directors in 1998, we are
authorized to repurchase 23,809 shares of our common stock to be held as
treasury shares for future use. During the fiscal year ended December 31, 2005,
we did not repurchase any shares of common stock. At December 31, 2005, 529
repurchased shares remain available for future use and 16,180 shares remain
available for repurchase under the plan.

     Capital expenditures were $14,519 and patent development costs were
$105,080 for the year ended December 31, 2005. Capital expenditures were $73,526
and patent development costs were $36,591 for the year ended December 31, 2004.
We anticipate additional capital and patent expenditures will be approximately
$100,000 for the fiscal year ending December 31, 2006.

     On July 10, 2003, the Board of Directors approved retention payments for
certain key employees, including certain executive officers, in order to enhance
retention of those employees. We made payments of approximately $84,000 on
January 8, 2004 and we made payments of approximately $153,000 on July 2, 2004.
On August 31, 2005, at the direction of our Board of Directors, we discontinued
all research and development activities and terminated substantially all of our
non-management personnel. We made payments of approximately $156,839 in
connection with this staff reduction and related expenses. In September 2005,
the Company entered into transition agreements with its executive officers. The
transition agreements terminated the existing employment and severance
agreements between the Company and each executive. Pursuant to the terms of the
transition agreements, the executives agreed that they would remain employed by
the Company until November 30, 2005. Three executives executed amendments to
their transition agreements extending their employment through December 31, 2005
and beyond. We made payments of approximately $709,646 in connection with all
executive transition agreements. We also made aggregate payments of
approximately $35,000 on November 30, 2005 and $35,000 on December 15, 2005
under a separate provision of the transition agreements. There are no further
payments due as a result of the staff reduction or under the transition
agreements.

     As of December 31, 2005, we had $3,023,436 in cash, cash equivalents and
short-term investments. As noted above, on February 13, 2006 we received
$5,755,000 in gross proceeds ($5,265,100 net of issuance costs but before legal
and accounting costs) from the sale of our Series C Preferred Stock and warrants
to purchase shares of our common stock. We believe that our existing cash and
cash equivalents will be sufficient to meet our operating expenses and capital
expenditure requirements for at least the next twelve months. Our cash
requirements may vary materially from those now planned because of changes in
the focus and direction of our research and development programs, competitive
and technical advances, patent developments or other developments. We will
require additional financing to continue operations after we exhaust our current
capital resources and to continue our long-term plans for clinical trials and


                                       39


new product development. We expect to continue financing our operations through
sales of our securities, strategic alliances or other financing vehicles, if
any, that might become available to us on terms that we deem acceptable.

     We do not enter into financial instrument transactions for trading or
speculative purposes. We do not intend to establish any special purpose entity
and do not have any material off balance sheet financing transactions. We do not
believe that inflation will have any significant effect on the results of our
operations.

     At December 31, 2005, the Company had no long-term contractual obligations.

RECENT ACCOUNTING PRONOUNCEMENTS

     In December 2004, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 123R, Share-Based Payment ("SFAS
No. 123R"). This Statement is a revision of SFAS No. 123, Accounting for
Stock-Based Compensation, and supersedes Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees, and its related implementation
guidance. SFAS No. 123R focuses primarily on accounting for transactions in
which an entity obtains employee services in share-based payment transactions.
The Statement requires entities to recognize stock compensation expense for
awards of equity instruments to employees based on the grant-date fair value of
those awards (with limited exceptions). SFAS No. 123R is effective for the first
fiscal year that begins after December 15, 2005. MacroChem Corporation expects
to adopt SFAS No. 123R using the Statement's modified prospective application
method. The Company does not yet have an estimate of the effect on its
statements of operations of adopting SFAS No. 123R.

     In May 2005, the FASB issued Statement of Financial Accounting Standards
No. 154, "Accounting Changes and Error Corrections, a replacement of APB Opinion
No. 20, Accounting Changes and FASB Statement No. 3, Reporting Accounting
Changes in Interim Financial Statements" ("SFAS No. 154"). SFAS No. 154 provides
guidance on the accounting for and reporting of accounting changes and error
corrections. It establishes, unless impracticable, retrospective application as
the required method for reporting a change in accounting principle in the
absence of explicit transition requirements specific to the newly adopted
accounting principle. SFAS No. 154 also provides guidance for determining
whether retrospective application of a change in accounting principle is
impracticable and for reporting a change when retrospective application is
impracticable. The provisions of SFAS No. 154 are effective for accounting
changes and corrections of errors made in fiscal periods beginning after
December 15, 2005. The adoption of the provisions of SFAS No. 154 is not
expected to have a material impact 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, 2005, we were exposed to market risks, which relate
primarily to changes in U.S. interest rates. Our 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 in interest rates would not
have a material effect on our 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, 2005, based on December
31, 2005 balances.

     THE FOREGOING STATEMENTS IN THIS REPORT INCLUDE FORWARD-LOOKING STATEMENTS

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of MacroChem Corporation:

We have audited the accompanying balance sheet of MacroChem Corporation (the
"Company") as of December 31, 2005, and the related statements of operations,
stockholders' equity, and cash flows for the year ended December 31, 2005. 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 audit.

We conducted our audit in accordance with the auditing standards of the Public
Company Accounting Standards Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. The Company is not
required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting. Our audit included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Company's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company as of December 31, 2005, and the
results of their operations and their cash flows for the year ended December 31,
2005 in conformity with accounting principles generally accepted in the United
States of America.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of MacroChem Corporation:

We have audited the accompanying balance sheets of MacroChem Corporation (the
"Company") as of December 31, 2004, and the related statements of operations,
stockholders' equity, and cash flows for each of the two years in the period
ended December 31, 2004. 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 the auditing standards of the Public
Company Accounting Standards Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. The Company is not
required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting. An audit includes consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Company's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, 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 the Company as of December 31, 2004, and the
results of their operations and their cash flows for each of the two years in
the period ended December 31, 2004 in conformity with accounting principles
generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements at December 31, 2004, the Company's recurring losses
from operations raised substantial doubt about its ability to continue as a
going concern. Management's plans concerning these matters are also described in
Note 1. The financial statements do not include any adjustments that might
result from the outcome of the uncertainty.

                          NOTES TO FINANCIAL STATEMENTS

     All references to share amounts, share prices and per share data in these
Notes to Financial Statements reflect both the 1-for-7 reverse stock split
effected on December 30, 2005 and the 1-for-6 reverse stock split effected on
February 9, 2006. Accordingly, where appropriate, share amounts, share prices
and per share data have been adjusted to give retroactive effect of the reverse
splits.

1.   NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.

     MacroChem Corporation (the "Company") is a specialty pharmaceutical company
that develops and seeks to commercialize pharmaceutical products using its
proprietary drug delivery technologies.

     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, 2004, the Company's accumulated deficit was approximately $76.8
million. At December 31, 2004, the Company believed that its existing cash and
cash equivalents were sufficient to fund operations under the Company's
operating plan until July 2005. At December 31, 2005, the Company's accumulated
deficit was approximately $82,584,992. 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. The Company believes that its existing cash
and cash equivalents will be sufficient to fund operations under the Company's
current plan for at least the next twelve months. The Company's cash
requirements may vary materially from those now planned because of changes in
the focus and direction of its research and development programs, competitive
and technical advances, patent developments or other developments.

     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 fair market value of
warrants included in liabilities, 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


                                       50


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 and cash
equivalents, 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, 2005 and 2004 are primarily comprised of government
agency securities and certificates of deposit.

     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 - Short-term investments are a liquid money market
mutual fund with a carrying value of $0 and $1,185,406 at December 31, 2005 and
2004, 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 three 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
patent costs and deferred patent application costs related to patents that are
considered to have limited future value are charged to expense. Accumulated
amortization aggregated approximately $324,008 and $274,379, respectively, at
December 31, 2005 and 2004. 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.

     LONG-LIVED ASSETS - The Company reviews its long-lived assets for
impairment when events or changes in circumstances indicate that the carrying
amount of a long-lived asset may not be recoverable. Recoverability of such
assets to be held and used is measured by a comparison of the carrying amount of
the asset to future undiscounted net cash flows expected to be generated by the
asset. If such assets are considered to be impaired, the impairment to be
recognized is measured by the amount by which the carrying amount of the assets
exceeds the fair value of the assets. Following a complete review of the results
of a Phase 2 pharmacodynamic study of Topiglan in which Topiglan did not meet
its primary clinical endpoints, the Company has no plans for further clinical
studies of Topiglan at this time. Accordingly, in 2004, the Company recorded a
reduction of $124,853 to the carrying value of certain patent assets related to
Topiglan.

     REVENUE RECOGNITION - The Company's business seeks to generate revenues
through the development, commercialization and licensing of drug products based
upon the Company's intellectual property. Revenues derived or expected to be
derived from the sale, assignment, transfer or licensing of patents or other


                                       51


intellectual property are recognized based upon the terms of the relevant
agreement.

     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.

     STOCK BASED COMPENSATION - The Company has applied the intrinsic value
method of accounting for stock options and awards granted to employees. The
Company has accounted for stock options and awards to non-employees using the
fair value method.

     Under the intrinsic value method, compensation associated with stock awards
to employees is determined as the difference, if any, between the current fair
value of the underlying common stock on the date compensation is measured and
the price an employee must pay to exercise the award. The measurement date for
employee awards is generally the date of grant. Under the fair value method,
compensation associated with stock-based awards to non-employees is determined
based on the estimated fair value of the award itself, measured using either
current market data or an established option pricing model. The measurement date
for non-employee awards is generally the date performance of services is
complete.

     The Company has used the intrinsic value method to account for stock-based
compensation to employees and directors. The following table illustrates the
effect on net loss and net loss per share if the Company had applied the fair
value method to stock-based employee and director compensation:

     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:




                                                 2005             2004              2003

Risk-free interest rate                     3.82% - 4.25%     3.05% - 4.14%     2.62%-3.47%
Expected life of option grants                 6 years           6 years          6 years
Expected volatility of underlying stock          100%              97%              97%
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 2005, 2004 and
2003 were $10.02, $51.24 and $36.12, 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.

     INCOME TAXES - The Company recognizes deferred tax assets and liabilities
for the expected future tax consequences of events that have been included in
the Company's financial statements or tax returns. Deferred tax assets and
liabilities are determined based upon the difference between the financial
reporting basis and the tax basis of existing assets and liabilities using
enacted tax rates expected to be in effect in the year(s) in which the
differences are expected to reverse. A valuation allowance is provided against
deferred tax assets if it is more likely than not that such assets will not be
realized.

     REVERSE STOCK SPLITS - On December 30, 2005 we implemented a 1-for-7
reverse stock split of our common stock and on February 9, 2006 we implemented a
subsequent 1-for-6 reverse stock split of our common stock. Unless otherwise
noted, data used throughout the Financial Statements have been adjusted to
reflect these reverse splits.

     NET 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 2005, 2004 and 2003, basic and diluted per share amounts
are the same. For the years ended December 31, 2005, 2004 and 2003, 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 under the treasury stock
method for 2005, 2004 and 2003 were 2,807,673, 155,919 and 129,785 shares,
respectively.

     RECENT ACCOUNTING PRONOUNCEMENT - In December 2004, the Financial
Accounting Standards Board ("FASB") issued Statement of Financial Accounting
Standards No. 123R, Share-Based Payment ("SFAS No. 123R"). This Statement is a
revision of SFAS No. 123, Accounting for Stock-Based Compensation, and
supersedes Accounting Principles Board Opinion No. 25, Accounting for Stock
Issued to Employees, and its related implementation guidance. SFAS No. 123R


                                       53


focuses primarily on accounting for transactions in which an entity obtains
employee services in share-based payment transactions. The Statement requires
entities to recognize stock compensation expense for awards of equity
instruments to employees based on the grant-date fair value of those awards
(with limited exceptions). SFAS No. 123R is effective for the fiscal year that
begins after December 15, 2005. MacroChem Corporation expects to adopt SFAS No.
123R using the Statement's modified prospective application method. The Company
does not yet have an estimate of the effect on its statements of operations of
adopting SFAS No. 123R.

     In May 2005, the FASB issued Statement of Financial Accounting Standards
No. 154, "Accounting Changes and Error Corrections, a replacement of APB Opinion
No. 20, Accounting Changes and FASB Statement No. 3, Reporting Accounting
Changes in Interim Financial Statements" ("SFAS No. 154"). SFAS No. 154 provides
guidance on the accounting for and reporting of accounting changes and error
corrections. It establishes, unless impracticable, retrospective application as
the required method for reporting a change in accounting principle in the
absence of explicit transition requirements specific to the newly adopted
accounting principle. SFAS No. 154 also provides guidance for determining
whether retrospective application of a change in accounting principle is
impracticable and for reporting a change when retrospective application is
impracticable. The provisions of SFAS No. 154 are effective for accounting
changes and corrections of errors made in fiscal periods beginning after
December 15, 2005. The adoption of the provisions of SFAS No. 154 is not
expected to have a material impact on the Company's financial position or
results of operations.

4.   STOCKHOLDERS' EQUITY.

     AUTHORIZED CAPITAL STOCK - Authorized capital stock consists of 100,000,000
shares of $.01 par value common stock of which 997,438 shares are issued
(996,909 are outstanding) and 5,177,429 are reserved for issuance upon exercise
of common stock options and warrants and conversion of Series C Cumulative
Convertible Preferred Stock at December 31, 2005. Authorized preferred stock
totals 6,000,000 shares, of which 500,000 shares have been designated Series A
Preferred Stock, 600,000 shares have been designated Series B Preferred Stock
and 1500 shares have been designated Series C Cumulative Convertible Preferred
Stock (250 shares were outstanding at December 31, 2005). The Series C Preferred
Stock has a liquidation value of $10,000 per share, is entitled to a dividend of
10% per annum, payable in cash or shares of our common stock at our option,
which dividend rate is subject to increase to 14% upon the occurrence of certain
events. The Series C Preferred Stock is redeemable at the holder's election in
the event the Company fails or refuses to convert any shares of Series C
Preferred Stock in accordance with the terms of the Certificate of Designation,
Rights and Preferences of the Series C Preferred Stock. The number of shares of
common stock into which each share of Series C Preferred Stock is convertible is
determined by dividing the liquidation value per share plus all accrued and
unpaid dividends thereon by $1.05. The conversion price for the Series C
Preferred Stock and the warrant exercise price are each subject to a reset
adjustment such that if the average of the price of the common stock over the
twenty trading days immediately preceding May 8, 2006 (the "Average Price") is
lower than the conversion and/or exercise price, then such conversion and/or
exercise price shall be adjusted to equal the Average Price. During 1998, the
Company's Board of Directors authorized the repurchase of up to 23,809 shares of
common stock at market price. The Company repurchased no shares in 2003, 2004

     STOCK AND STOCK OPTION ISSUANCES TO NON-EMPLOYEES - During 2005, there were
no options granted to non-employees or consultants. During 2004 and 2003, the
Company issued 357 and 1,130 stock grants and options, respectively, to
non-employees and consultants and recorded unearned compensation of $15,322 and
$4,902, respectively.

     STOCK AND STOCK OPTION ISSUANCES OUTSIDE THE STOCK OPTION PLANS - During
2003, an option to purchase 11,904 shares of common stock was granted to Robert
J. DeLuccia, the Company's new Chief Executive Officer, of which 3,571 shares
vested immediately, with the remainder vesting over two years, with an exercise
price of $44.52 per share.

     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 42/100th of a share of Series B Preferred Stock of the Company at an
initial exercise price of $2,100.00, subject to adjustments for stock dividends,


                                       58


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.

     On December 23, 2005, the shareholder rights plan was amended to provide
that the acquisition of the Company's Series C Cumulative Convertible Preferred
Stock and warrants to acquire shares of its common stock by the purchasers in
the Company's recent private placement, and any subsequent acquisition by the
purchasers of common stock upon the conversion or exercise of those securities,
would not result in the Rights becoming exercisable.

     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.

     At December 31, 2005, the Company had no long-term contractual obligations.

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 in all periods reported
and recoverability of these losses in future tax filings is uncertain. As of
December 31, 2005, the Company has available net operating loss carryforwards of
approximately $69,339,393 for federal income tax purposes, expiring through 2025
and $44,827,346 for state income tax purposes, expiring through 2010. In
addition, the Company has unused investment and research and development tax
credits for federal and state income tax purposes aggregating $1,576,194 and
$855,973, 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.

     Income taxes computed using the federal statutory income tax rate differs
from the Company's effective tax rate primarily due to the following:



                                                       Year ended December 31,

     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, 2005 and 2004 are as follows:



                                                             2005               2004

                                                            28,818,000         27,473,000

     For the years ended December 31, 2005 and 2004, the valuation allowance was
increased by approximately $1,345,000 and $2,639,000, respectively, due to the
uncertainty of future realization of currently generated net operating loss and
tax credit carryforwards.

7.  EMPLOYEE BENEFIT PLAN.

     The Company sponsors a qualified 401(k) Retirement Plan (the "Plan") under
which employees are allowed to contribute certain percentages of their pay, up
to the maximum allowed under Section 401(k) of the Internal Revenue Code.
Company contributions to the Plan are at the discretion of the Board of
Directors. The Company contributed 953 shares of common stock in 2005, 1,286
shares of common stock in 2004 and 1,642 shares of common stock in 2003, valued
at $15,610, $59,060 and $48,719, respectively. The Company also contributed
$42,539 in cash to the Plan in 2005.

8.  SUBSEQUENT EVENT.

     In February 2006, the Company completed a private placement of its
securities to institutional investors, consisting of two closings, for
approximately $8.25 million in gross proceeds. The first closing of the private
placement, in which institutional investors acquired 250 shares of Series C
Cumulative Convertible Preferred Stock and six-year warrants to purchase
2,380,951 shares of common stock at an exercise of $1.26 per share, for an
aggregate purchase price of $2.5 million, took place on December 23, 2005 and is
reflected in the financial statements at December 31, 2005. The second closing
of the private placement, in which institutional investors acquired 575.5 shares
of Series C Cumulative Convertible Preferred Stock and six-year warrants to
purchase 5,480,961 shares of the Company's common stock at an exercise price of
$1.26 per share, for an aggregate purchase price of approximately $5.75 million,
occurred on February 13, 2006. As of December 31, 2005, none of the $1.26
warrants had been exercised. The placement agent in the transaction received a
warrant to purchase approximately 548,095 shares of common stock at a purchase
price of $1.05 for a period of six years. The Series C Preferred Stock has a
liquidation value of $10,000 per share, is entitled to a dividend of 10% per
annum, payable in shares of our common stock at our option, which dividend rate
is subject to increase to 14% upon the occurrence of certain events. The number
of shares of common stock into which each share of Series C Convertible
Preferred Stock is convertible is determined by dividing the liquidation value
per share plus all accrued and unpaid dividends thereon by $1.05. Unless a
holder of Series C Cumulative Convertible Preferred Stock elects otherwise, its


                                       60


ability to convert its Series C Cumulative Convertible Preferred Stock into
common stock or to vote on an as-if-converted to common stock basis is
restricted to the extent that such conversion would result in the holder owning
more than 4.95% of our issued and outstanding common stock or voting together
with the common stock on an as-if-converted to common stock basis in respect of
more than 4.95% of our issued and outstanding common stock. The warrants issued
in the private placement are subject to a similar restriction on their exercise.
SCO Capital Partners LLC, Beach Capital LLC and Perceptive Life Sciences Master
Fund Ltd. ("Perceptive") have elected not to be governed by these restrictions,
although we have entered into an agreement with Perceptive whereby Perceptive's
ability to convert or vote its shares of Series C Preferred Stock is subject to
a beneficial ownership cap of 9.95% instead of 4.95%.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
         FINANCIAL DISCLOSURE.

     On January 24, 2006, Deloitte & Touche LLP ("Deloitte") resigned as our
independent registered public accounting firm.

     Deloitte's report relating to the financial statements of the Company for
the year ended December 31, 2004 did not contain an adverse opinion or a
disclaimer of opinion, and was not qualified or modified as to audit scope or
accounting principles, except the report contained an explanatory paragraph
relating to the Company's ability to continue as a going concern. Deloitte's
report relating to the financial statements of the Company for the year ended
December 31, 2003 did not contain an adverse opinion or a disclaimer of opinion,
and was not qualified or modified as to uncertainty, audit scope or accounting
principles.

     During the Company's fiscal years ended December 31, 2003 and December 31,
2004, and through January 24, 2006, the date which Deloitte resigned, the
Company had no disagreement with Deloitte on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedure,
which, if not resolved to Deloitte's satisfaction, would have caused Deloitte to
make reference to the subject matter of the disagreement in connection with its
reports for such periods. During the Company's fiscal years ended December 31,
2003 and December 31, 2004, and through January 24, 2006, there were no
reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

     On February 14, 2006 and effective the same date, on the recommendation of
the Company's Audit Committee, the Company engaged Vitale, Caturano & Company
Ltd. ("Vitale") as its independent registered public accounting firm to audit
the Company's financial statements as of and for the fiscal year ending December
31, 2005 and to perform procedures related to the financial statements included
in the Company's quarterly reports on Form 10-Q, beginning with quarter ended
March 31, 2006.

     During the two most recent fiscal years and through February 14, 2006, the
Company has not consulted with Vitale on any matter which was the subject of any
disagreement or any reportable event as defined in Regulation S-K Item
304(a)(1)(iv) and Regulation S-K Item 304(a)(1)(v), respectively, or on the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's financial statements, relating to which either a written report


                                       61


was provided to the Company or oral advice was provided that Vitale concluded
was an important factor considered by the Company in reaching a decision as to
the accounting, auditing or financial reporting issue.

ITEM 9A. CONTROL AND PROCEDURES.

     As of the end of the period covered by this report, we carried out a
review, under the supervision and with the participation of our management,
including our Chief Executive Officer and Chief Financial Officer, of the
effectiveness of our disclosure controls and procedures (as defined in the SEC
rules promulgated under the Securities Exchange Act of 1934, as amended), which
are designed to ensure that information required to be disclosed in our
Securities and Exchange Commission reports is properly and timely recorded,
processed, summarized and reported. Based upon that review, our Chief Executive
Officer and Chief Financial Officer concluded that while our disclosure controls
and procedures are effective in timely alerting them to material information
required to be included in our periodic filings with the Securities and Exchange
Commission, there is a lack of segregation of duties at the Company due to the
small number of employees dealing with general administrative and financial
matters. This constitutes a significant deficiency in financial reporting.
However, at this time management has decided that, considering the employees
involved and the control procedures in place, the risks associated with such
lack of segregation are insignificant, and the potential benefits of adding
additional employees to clearly segregate duties do not justify the expenses
associated with such increases. Management will continue to evaluate this
segregation of duties.

     There were no changes in our internal control over financial reporting that
occurred during the quarter ended December 31, 2005 that have materially
affected, or are reasonably likely to materially affect, our internal control
over financial reporting.

ITEM 9B. OTHER INFORMATION.

     Not applicable.

reviewing our financial results and recommending the selection of our

controls; and (3) reviewing the scope of the audit, the fees charged by the

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

officers and directors, and persons who beneficially own more than 10 percent of
the Company's Common Stock to file reports of ownership and changes in ownership

copies of such reports received by it, and written representations from certain

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The following table sets forth, as of March 7, 2006 (except as noted),
information concerning ownership of our common stock by (1) each person known by
us to be the beneficial owner of more than five percent (5%) of our common
stock, (2) each of our directors, (3) each of the executive officers named in
the Summary Compensation Table under "Executive Officers' Compensation" above
and (4) all directors and executive officers as a group. Except as otherwise
indicated, the stockholders listed in the table have sole voting and investment
powers with respect to the shares indicated. There were a total of 996,909
shares of our common stock outstanding on March 7, 2006.

                                       71


     We have determined the number of shares beneficially owned by each
stockholder under rules promulgated by the SEC. The information is not
necessarily indicative of beneficial ownership for any other purpose. Under
these rules, beneficial ownership includes any shares as to which the individual
or entity has sole or shared voting or investment power and any shares as to
which the individual or entity has the right to acquire beneficial ownership
within 60 days after March 17, 2005 through the exercise of any stock option,
warrant or other right. The inclusion in the following table of those shares,
however, does not constitute an admission that the named stockholder is a direct
or indirect beneficial owner.
