                              MACROCHEM CORPORATION

     We are a specialty pharmaceutical company that develops and seeks to
commercialize pharmaceutical products. Currently, our portfolio of proprietary
product candidates is based on our drug delivery technologies: SEPA, MacroDerm
and DermaPass. Our 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. Our composition of matter patent on the SEPA family of
compounds expired in November 2006. We 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
nineteen 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 commenced a Phase 2 efficacy study of EcoNail in the third quarter of
2006. This study is being conducted through a contract research organization
with significant experience in onychomycosis trials.

     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
the U.S. 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


                                       1

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. 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 proprietary
products through the use of our 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.

     o    IN-LICENSE SELECTED PRODUCTS AND TECHNOLOGIES. We intend to identify
          and in license 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 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.

                          RISKS AFFECTING OUR BUSINESS

     Our business is subject to a number of risks that we highlight in the
section entitled "Risk Factors" immediately following this prospectus summary.
As of the date of this prospectus, we have not generated any meaningful revenues
from operations and we have sustained significant operating losses. As of
December 31, 2006, we had an accumulated deficit of approximately $81,385,779.
We anticipate that we will continue to incur significant losses for the
foreseeable future. Our technologies are in discovery or developmental stages
and must undergo a rigorous regulatory approval process, which includes
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.

                                  RISK FACTORS

     INVESTING IN OUR COMMON STOCK IS RISKY. IN ADDITION TO THE OTHER
INFORMATION IN THIS PROSPECTUS, 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 operating losses every year since we
began doing business and we anticipate that we will continue to incur operating
losses for the foreseeable future. As of December 31, 2006, we had an
accumulated deficit of approximately $81,385,779. For the fiscal year ended
December 31, 2006, we had net income of $1,951,279, however, such net income was
the result of a non-cash gain in a liability classified warrant caused by a
decline in our stock price. For the fiscal years ended December 31, 2005 and
2004, we had a net loss of $5,760,475 and $8,274,521, 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 resumed
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.

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



                                       4

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.

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 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,

                                       5

          how these 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 GENERATE PROFITS FROM OPERATIONS.

     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
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.

                                       6

     Our composition of matter patent covering SEPA expired 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.

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,



                                       7

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.

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.

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

     In our private placement which closed in December 2005 and February 2006,
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 Cumulative Convertible Preferred Stock will be subject to a beneficial
ownership cap of 9.95% instead of 4.95%. Consequently, as of March 7, 2007,
giving effect to the beneficial ownership cap restrictions, the Series C
Cumulative Convertible Preferred Stock acquired by the investors is convertible
into 4,967,920 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 63.5% of the voting power of
our outstanding securities. Assuming both the conversion of the Series C


                                       8

Cumulative Convertible Preferred Stock and the exercise of all of the Warrants
held by the investors, in each case without regard to the beneficial ownership
cap restrictions as of March 7, 2007, the investors would hold approximately
84.9% 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.

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 the selling security holders listed
in this prospectus, own large blocks of our voting stock. The resale of 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) is being registered under the registration statement of which this
prospectus forms a part. 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., 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;

     A number of companies, including NexMed, Inc./Novartis AG, IVREA/MediQuest
Therapeutics, Inc., and Schering-Plough/Anacor Pharmaceuticals, Inc. are also
developing topical therapies for onychomycosis. In addition, a number of other
companies, including Auxilium Pharmaceuticals, Inc., are also developing topical
and/or transmucosal testosterone products.

     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


                                       9

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
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.

                                       10

     Over the two-year period ending December 31, 2006, 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
$33.60 to a low of $$0.26. On March 16, 2007, the closing price for our common
stock on the OTC Bulletin Board was $0.55. 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.
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, 2007, our Series C Cumulative Convertible Preferred Stock is
convertible into an aggregate of, giving effect to the beneficial ownership
restrictions on conversion, 4,967,920 shares of common stock (7,442,853 shares
of common stock without regard to the beneficial ownership restrictions on
conversion). In addition, we are required to issue quarterly dividends on our
Series C Convertible Preferred Stock, which we may elect to pay in shares of our
common stock. In addition, as of March 7, 2007, there are outstanding and
exercisable warrants to purchase approximately 8,701,573 shares of our common
stock, at a weighted average exercise price of $1.48 per share. As of March 7,
2007, there also are outstanding and exercisable options to purchase
approximately 724,850 shares of our common stock, at a weighted average exercise
price of $14.04 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.

     Before you invest in our securities, you should be aware that the
occurrence of the events described in these risk factors and elsewhere in this
prospectus could have an adverse effect on our business, results of operations,
financial position and prospects. You should read this prospectus completely and

                                 USE OF PROCEEDS

     We will not receive any proceeds from the sale of shares of common stock by
the selling security holders. We will receive proceeds only upon the exercise of
the warrants held by the selling security holders. To the extent all of the
outstanding warrants held by the selling security holders are exercised at their
current exercise prices, we would receive approximately $10,731,500 in cash
proceeds, unless these warrants are exercised on a cashless basis pursuant to
their terms. The proceeds, if any, we receive from the exercise of the warrants
will be used for working capital requirements and other general corporate
purposes.

                                 DIVIDEND POLICY

     We have never paid cash dividends on our common stock and our Board of
Directors does not contemplate declaring any dividends in the foreseeable
future. We intend to retain any earnings to finance research, development, and
expansion of our business.

                      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 PROSPECTUS. IN ADDITION TO HISTORICAL INFORMATION, THE FOLLOWING
DISCUSSION AND OTHER PARTS OF THIS PROSPECTUS 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 PROSPECTUS.

GENERAL

     We are a specialty pharmaceutical company that develops and seeks to
commercialize pharmaceutical products. Currently, our portfolio of proprietary
product candidates is based on our drug delivery technologies: SEPA, MacroDerm
and DermaPass. Our 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 operating 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, 2006, we had an
accumulated deficit of $81,385,779. 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 prospectus 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;

     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.

     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 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


                                       15


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 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.

     We believe that our existing cash, cash equivalents and short term
investments of $4,895,302 as of December 31, 2006 will be sufficient to meet our
current operating expenses and capital expenditure requirements for at least the
next twelve months.

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

     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, 2006, we spent $679,759 on research and development,
including $591,008 in costs associated with clinical trials for EcoNail, and
$88,751 in costs not specifically tracked to a project. Opterone was not in a
clinical trial in 2006. For the fiscal year ended December 31, 2005, we spent
$2,291,721 on research and development, including $229,650 and $111,739 in costs
associated with clinical trials for EcoNail and Opterone, respectively, and
$1,950,332 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. 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, 2007, we expect to
continue to spend significant amounts on clinical trials for EcoNail, which we
estimate may cost up to $1,200,000.

     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
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


                                       16


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.

     STOCK BASED COMPENSATION. On January 1, 2006, the Company adopted Statement
of Financial Accounting Standards ("SFAS") No. 123(R), "Share-Based Payment,"
using the modified prospective method, which requires measurement of
compensation cost for all stock awards at fair value on the date of grant and
recognition of compensation over the requisite service period for awards
expected to vest. The fair value of stock options is estimated using the
Black-Scholes valuation model, and the fair value of restricted stock units is
determined based on the number of shares granted and the quoted price of the
Company's common stock on the date of grant. Such value is recognized as expense
over the requisite service period, net of estimated forfeitures, using the
straight-line attribution method. The estimate of awards that will ultimately
vest requires significant judgment, and to the extent actual results or updated
estimates differ from the Company's current estimates, such amounts will be
recorded as a cumulative adjustment in the period estimates are revised. The
Company considers many factors when estimating expected forfeitures, including
types of awards, employee class and historical employee attrition rates. Actual
results, and future changes in estimates, may differ substantially from the
Company's current estimates.

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 prospectus 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 . Research and development costs are expensed as
incurred.

     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
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, 2006, we had federal tax net operating loss carryforwards of
approximately $73,367,079, which expire through 2026. We also have research and
development credit carryforwards of $2,475,048. 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.

     WARRANTS LIABILITY. Based on certain terms in the warrants that we issued
in connection with the sale of our Series C Cumulative Convertible Preferred
Stock, we determined that the warrants should be classified as a liability and
valued at fair market value each reporting period, with the changes in fair
value recorded in earnings, in accordance with EITF 00-19, "Accounting for
Derivative Financial Investments Indexed to, and Potentially Settled in, a


                                       17


Company's Own Stock." We will continue to evaluate the warrants under EITF 00-19
to determine when, if ever, they meet certain criteria under EITF 00-19 for
permanent equity.

     STOCK BASED COMPENSATION. On January 1, 2006, the Company adopted Statement
of Financial Accounting Standards ("SFAS") No. 123(R), "Share-Based Payment,"
using the modified prospective method, which requires measurement of
compensation cost for all stock awards at fair value on the date of grant and
recognition of compensation over the requisite service period for awards
expected to vest. The fair value of stock options is estimated using the
Black-Scholes valuation model, and the fair value of restricted stock units is
determined based on the number of shares granted and the quoted price of the
Company's common stock on the date of grant. Such value is recognized as expense
over the requisite service period, net of estimated forfeitures, using the
straight-line attribution method. The estimate of awards that will ultimately
vest requires significant judgment, and to the extent actual results or updated
estimates differ from the Company's current estimates, such amounts will be
recorded as a cumulative adjustment in the period estimates are revised. The
Company considers many factors when estimating expected forfeitures, including
types of awards, employee class and historical employee attrition rates. Actual
results, and future changes in estimates, may differ substantially from the
Company's current estimates.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 2006 COMPARED TO THE YEAR ENDED DECEMBER 31, 2005

     The Company had no revenues for the years ended December 31, 2006 and 2005,
respectively. For the year ending December 31, 2007, we do not expect to have
any revenues.

     Research and development costs for 2006 decreased by $1,611,962 from
$2,291,721 in 2005 to $679,759 in 2006, a 70.3% decrease. The decrease is
primarily attributable to the temporary cessation of research and development
activities in August 2005, resulting in a reduction in payroll and employee
related expenses of $692,824 and a reduction in lab operating expenses of
$674,166 for the year ended December 31, 2006. In addition, there was a decrease
in clinical development costs of $244,320. For the year ending December 31,
2007, we expect to incur clinical development costs of approximately $1,200,000.

     Marketing, general and administrative costs for 2006 increased by $724,914,
or 24.3% to $3,713,006, from $2,988,092 in 2005. The increase was primarily
attributable to the Company's adoption of SFAS No. 123(R), which requires the
expensing of stock options granted to employees based on the fair value on the
date of the grant, resulting in an expense of $941,127. In addition, expenses
related to conferences and investor meetings increased by approximately
$265,311. The effect of these amounts on marketing, general and administrative
expenses for the year 2006 was partially offset by savings attributable to a
staff reduction in August 2005 which resulted in a reduction of salary and
related expenses of approximately $603,428 during the year ended December 31,
2006. For the year ending December 31, 2007, we expect the marketing, general
and administrative expenses to approximate $2,750,000.

     For the year ended December 31, 2006, other income increased by $6,278,494
to $6,344,044 compared to $65,550 for the year ended December 31, 2005. This
gain is primarily a non-cash increase as a result of a change in the valuation
of warrants in accordance with EITF 00-19, "Accounting for Derivative Financial
Instruments Indexed to, and Potentially Settled in a Company's Own Stock" to
reflect a decline in price of our common stock for which the warrants are
exercisable. As a result, the fair value of the warrant liability decreased by
$6,100,615. Interest income for the year December 31, 2006 increased by $177,879
to $243,429 compared to interest income of $65,550 for the year ended December
31, 2005. The increase in interest income is due to the higher amounts of cash
available for investing purposes and higher interest rate returns available for
the cash that is invested.

     For the reasons described above, the Company's financial statements reflect
a net income of $1,951,279 for the year ended December 31, 2006 compared to a
net loss of $(5,760,475) for the year ended December 31, 2005.

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.

     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



                                       18


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.

     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.

     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.

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 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 ($5,186,908 net of
issuance costs) as a result of the sale of our Series C Cumulative Convertible
Preferred Stock in a private placement financing transaction.

     At December 31, 2006, working capital was approximately $4.8 million,
compared to $2.7 million at December 31, 2005. The increase in our working
capital reflects the receipt of private placement proceeds of $5,186,908 (net of
issuance costs) in February 2006, partially offset by the funds used in
operations.

     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 price 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 ($5,186,908 net of issuance costs) 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

                                       19

$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, 2006,
we did not repurchase any shares of common stock. At December 31, 2006, 529
repurchased shares remain available for future use and 16,180 shares remain
available for repurchase under the plan.

     There were no capital expenditures and patent development costs were
$40,770 for the year ended December 31, 2006. Capital expenditures were $14,519
and patent development costs were $105,080 for the year ended December 31, 2005.
We anticipate additional capital and patent expenditures will be approximately
$100,000 for the fiscal year ending December 31, 2007.

     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, 2006, we had $4,895,302 in cash, cash equivalents and
short-term investments. As noted above, on February 13, 2006 we received
$5,755,000 in gross proceeds ($5,186,908 net of issuance 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, cash equivalents and short-term
investments will be sufficient to meet our current 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
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, 2006, the Company had no long-term contractual obligations.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 2006, the FASB issued FASB Interpretation 48, "Accounting for
Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109" ("FIN
48"), which clarifies the accounting for uncertainty in income taxes recognized
in a company's financial statements in accordance with SFAS 109 "Accounting for
Income Taxes." FIN 48 prescribes a recognition threshold and measurement
attribute for the financial statement recognition and measurement of a tax
position taken or expected to be taken in a tax return. FIN 48 becomes effective
for fiscal years beginning after December 15, 2006. The Company does not expect
the adoption of FIN 48 to have a material impact on its financial position or
results of operations.

     In September 2006, the FASB issued Statement 157 "Fair Value Measurements"
("SFAS 157"), which establishes a framework for measuring fair value in
generally accepted accounting principles and expands disclosures about fair
value financial instruments. SFAS 157 becomes effective for fiscal years


                                       20


beginning after November 15, 2007. The Company will adopt this statement
prospectively once it is effective and applicable. The Company does not expect
SFAS 157 to have a material impact on its financial position or results of
operations.

     In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for
Financial Assets and Financial Liabilities ("SFAS 159"). SFAS 159 provides
companies with an option to report selected financial assets and liabilities at
fair value. SFAS 159 also establishes presentation and disclosure requirements
designed to facilitate comparisons between companies that choose different
measurement attributes for similar types of assets and liabilities and to
provide additional information that will help investors and other financial
statement users to more easily understand the effect of the company's choice to
use fair value on its earnings. Finally, SFAS 159 requires entities to display
the fair value of those assets and liabilities for which the company has chosen
to use fair value on the face of the balance sheet. SFAS 159 is effective as of
the beginning of an entity's first fiscal year beginning after November 15,
2007. Early adoption is permitted. The Company is currently assessing the impact
of SFAS 159 which it will be required to adopt.

     In September 2006, the Securities and Exchange Commission issued SAB 108,
which provided guidance on the consideration of the effects of prior year
misstatements in quantifying current year misstatements for the purpose of a
materiality assessment. SAB 108 was effective for fiscal years ending after
November 15, 2006. The adoption of SAB 108 did not have a material impact on the
Company's financial position or results of operations.

     The quarters ended March 31, June 30 and September 30, 2006 have been
restated (Notes 1 and 5). The restatement is in connection with the Series C
Cumulative Convertible Preferred Stock Offering, the Company issued warrants to
the private placement agent for services rendered. The fair value of the award
was originally accounted for as an offset to the proceeds of the Series C
Preferred offering and a credit to additional paid in capital. Upon further
review of the terms of the warrants, it was determined that the private
placement agent's warrants' put feature enables the holder, at their option, to
require the Company to repurchase the award for cash in the event of a change in
control. The Company determined that the warrants meet the definition of a
derivative investment as defined in SFAS 133, Accounting for Derivative
Financial Instruments Indexed to, and Potentially Settled in, a Company's Own
Stock, and should be adjusted to its current fair value at each reporting period
and classified as a warrant liability. As such, the net loss for the quarter
ended March 31, 2006 increased by $250,496, and the net income for the quarters
ended June 30, 2006 and September 30, 2006, increased by $260,764 and $438,854,
respectively.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

     As of December 31, 2006, 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, 2006, based on December
31, 2006 balances.

                                    BUSINESS

OVERVIEW

     We are a specialty pharmaceutical company that develops and seeks to
commercialize pharmaceutical products. Currently, our portfolio of proprietary
product candidates is based on our drug delivery technologies: SEPA, MacroDerm
and DermaPass. Our 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. Our composition of matter patent on the SEPA family of
compounds expired in November 2006. We 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
nineteen 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 commenced a Phase 2 efficacy study of EcoNail in the third quarter of
2006. This study is being conducted through a contract research organization
with significant experience in onychomycosis trials.

     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
the U.S. 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

                                       22

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. 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 proprietary
products through the use of our 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.
     o    IN-LICENSE SELECTED PRODUCTS AND TECHNOLOGIES. We intend to identify
          and in license 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 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;

                                       23

     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 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.

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.

                                       24


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
(terbinafine) and Sporanox (itraconazole). 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 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) (ciclopirox), 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 oral 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.

                                       25


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. Nineteen 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.

     In October 2006, we began enrollment in a Phase II study of EcoNail in
patients with onychomycosis. We expect to enroll approximately 40 patients in
this U.S. multi-center open label trial. Patients participating in the study,
which is being conducted under our U.S. Investigational New Drug application
filed with the FDA, will receive 48 weeks of treatment and will undergo efficacy
assessments using standard criteria of nail appearance and mycology. The study
protocol also specifies an interim assessment after all patients complete 24
weeks of treatment. At both the interim and final assessments, we plan to
utilize a panel of independent onychomycosis experts to assist with the efficacy
evaluations.

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.

     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


                                       26


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 the U.S. 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
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


                                       27


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;
     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., 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./Novartis AG, Schering-Plough/Anacor Pharmaceuticals, Inc. and
Ivrea/MediQuest Therapeutics, Inc., are also developing topical 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.

     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.

                                       28


     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
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.

                                       29


     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
unique formulations and the design of manufacturing processes for our drug
delivery technologies, we have contracted and will continue 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
$4,221,039, $2,291,721 and $679,759 during the years ended December 31, 2004,
2005 and 2006, respectively. We also rely upon third parties to conduct clinical
studies and to obtain FDA and other regulatory approvals.

PATENTS, TRADEMARKS AND LICENSE RIGHTS

     Our composition of matter patent on the SEPA family of compounds expired in
November 2006. We 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 2006, we did not file any new U.S. patent applications.

     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, 2006, we had five full time employees and one part-time
employee, none of whom are dedicated to research and development and regulatory
affairs. Effective as of March 15, 2007, Glenn E. Deegan resigned his position
as our Vice President and General Counsel and Secretary. None of our employees
are covered by a collective bargaining agreement, and we consider relations with
our employees to be good.

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.

                                       30


PROPERTIES.

     We currently occupy approximately 4,000 square feet of office space under a
sublease which terminates in January, 2008. This space is located within one
floor of a three story building in Wellesley Hills, 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.

LEGAL PROCEEDINGS.

     We are not currently engaged in any material legal proceedings.

     The following is a brief summary of Mark J. Alvino, a nominee for election
as a Director at our 2007 annual meeting of shareholders scheduled for May 10,
2007:

     MARK J. ALVINO has not previously served as a Director of MacroChem. He is

DIRECTOR INDEPENDENCE

     The Board of Directors believes that a majority of the Board members should
be independent directors as defined in National Association of Securities
Dealers Marketplace Rule 4200(a)(15) and as required by the established criteria
of the SEC. The Board of Directors also believes that it is appropriate for one
or more members of our management, including our Chief Executive Officer, to
serve as director. The Board of Directors has determined that Dr. Zabriskie, Dr.
Davis, Mr. Davis, Mr. Echenberg, Mr. Martin and Mr. Fischer are, and if elected
Mr. Alvino will be, each independent directors as defined in National
Association of Securities Dealers Marketplace Rule 4200(a)(15) and as required
by the established criteria of the SEC.

COMMITTEES OF THE BOARD OF DIRECTORS

     There are three standing committees of the Board of Directors: an Audit
Committee, a Compensation Committee and a Nominating and Corporate Governance
Committee.

AUDIT COMMITTEE

     Mr. Martin (Chairman), Dr. Davis and Mr. Echenberg serve as members of the

NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

     Mr. Echenberg (Chairman), Dr. Zabriskie, Dr. Davis and Mr. Martin serve on
the Nominating and Corporate Governance Committee, each of whom is an
independent director as defined in National Association of Securities Dealers
Marketplace Rule 4200(a)(15) and as required by the established criteria of the
SEC. The Nominating and Corporate Governance Committee was established on May 6,
2004, and its charter is available on the Company's website at
WWW.MACROCHEM.COM. Prior to the formation of the Nominating and Corporate
Governance Committee, its functions were carried out by the independent
directors of the Board. The purposes of the Nominating and Corporate Governance
Committee are (i) to identify individuals qualified to become members of the
Board, (ii) to select, or to recommend that the Board select, the director
nominees for the next annual meeting of shareholders and (iii) to develop and
recommend to the Board a set of corporate governance principles applicable to
the Company. The Company does not currently pay any third party a fee to assist
in the process of identifying and evaluating candidates for director. The
Company has not received any nominees for director from a stockholder or
stockholder group that beneficially owns more than 5% of the Company's common
stock. SCO Capital Partners LLC, a stockholder that beneficially owns more than
5% of the Company's Series C Preferred Stock, has the right, pursuant to the
amended and restated securities purchase agreement entered into in connection
with the private placement of our Series C Preferred Stock that closed in
December 2005 and February 2006, to designate two individuals to serve on our
board of directors for as long as at least 20% of the shares of Series C
Preferred Stock issued in that private placement remain outstanding. For 2007,
SCO Capital Partners LLC has designated Jeffrey B. Davis and Mark J. Alvino. The
Nominating and Corporate Governance Committee conducted their activities during
one (1) meeting of the full Board.

     The Company's Nominating and Corporate Governance Committee may consider
nominees for director of the Company submitted in writing to the Chairman of the
Committee, which are submitted by executive officers of the Company, current
directors of the Company, search firms engaged by the Committee, and by others
in its discretion and, in the circumstances provided below, shall consider
nominees for director proposed by a stockholder. Information with respect to the
proposed nominee shall have been provided in writing by the stockholder to the
Company's Secretary at MacroChem Corporation, 40 Washington Street, Suite 220,
Wellesley Hills, MA 02481, not less than 60 nor more than 90 days prior to the
anniversary date of the prior year's annual meeting, provided that if the
current year's annual meeting is not scheduled within 30 days of the anniversary
date of the prior year's annual meeting, notice from a stockholder shall be
considered timely if it is provided not later than the tenth day following which
the notice of the annual meeting was mailed or public disclosure of the date of
the annual meeting was made, whichever occurs first. The information shall
include the name of the nominee, and information with respect to the nominee as
would be required under the rules and regulations of the Securities and Exchange
Commission to be included in the Company's Proxy Statement if the proposed
nominee were to be included therein. In addition, the stockholder's notice shall
also include the class and number of shares the stockholder owns, a description
of all arrangements and understandings between the stockholder and the proposed
nominee, a representation that the stockholder intends to appear in person or by
proxy at the meeting to nominate the person named in its notice, a
representation as to whether the stockholder intends to deliver a proxy
statement to or solicit proxies from shareholders of the Company and information
with respect to the stockholder as would be required under the rules and
regulations of the Securities and Exchange Commission to be included in the
Company's Proxy Statement.

     The Nominating and Corporate Governance Committee generally identifies
potential candidates for director by seeking referrals from the Company's
management and members of the Board of Directors and their various business
contacts. Candidates are evaluated based upon factors such as independence,
knowledge, judgment, integrity, character, leadership, skills, education,
experience, financial literacy, standing in the community and ability to foster
a diversity of backgrounds and views and to complement the Board's existing
strengths. There are no differences in the manner in which the Committee will
evaluate nominees for director based on whether the nominee is recommended by a
stockholder.

                COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS

COMPENSATION DISCUSSION AND ANALYSIS

OVERVIEW OF COMPENSATION PROGRAM

     The Compensation Committee, which consists of three independent directors,
is responsible for determining the compensation of the Company's executive
officers, making awards under the Company's stock option plans and making
recommendations to the Board of Directors with regard to the adoption of new
employee benefit plans. The Compensation Committee reviews the proposals of the
Chief Executive Officer concerning executive compensation for other executive
officers and makes a final determination or recommendation concerning the scope
and nature of compensation arrangements. The action or recommendation of the
Committee is reported to the Company's entire Board of Directors.

COMPENSATION PHILOSOPHY AND OBJECTIVES

     The Compensation Committee believes that compensation of our executive
officers should encourage creation of stockholder value and achievement of
strategic corporate objectives and allow us to attract, retain and motivate
superior executives and to compensate these executives in a manner that both
recognizes their individual performance and aligns their interests with the
interests of MacroChem's stockholders. To that end, the Compensation Committee

                                       35

believes that executive compensation should include a mix of both cash and
equity-based compensation that is competitive with companies in the specialty
pharmaceutical industry, taking into account relative company size and
performance as well as individual responsibilities and performance.

     The Committee's decisions and activities during 2006 were guided, to a
significant extent, by the Company's financial condition and outlook during the
year. Accordingly, given the Company's lack of financial resources during 2006,
the conservation of cash resources was a priority for the Committee.

 COMPENSATION COMPONENTS

     BASE SALARY. In general, in determining base salaries for executives the
Compensation Committee takes into account (i) the executive's individual
performance and contribution to the management team; (ii) the performance of
MacroChem over the evaluation period by reference to corporate objectives
jointly formulated by the Chief Executive Officer and the officers; and (iii)
base salaries of executives in comparable positions in comparable companies. In
setting base salary, the Committee also takes into account all components of an
executive officer's compensation package. In determining base salary, the
Committee reviews the foregoing factors as they relate to each executive
individually and applies each factor subjectively, without reference to specific
criteria. The Committee does not weigh any one factor more or less heavily than
any other and considers the input of the Chief Executive Officer and, as
necessary, outside experts in reaching its determinations.

     ANNUAL BONUS. Our compensation program includes eligibility for an annual
performance-based cash bonus to executive officers. The amount of the cash bonus
depends on the level of achievement of corporate and individual objectives.
Annual performance bonuses are set at the discretion of the Board. Pursuant to
his employment agreement, our chief executive officer has a target annual
performance bonus of 40% of his base salary.

     During 2006, we awarded our chief executive officer a special payment of
$50,000 in recognition of his efforts to secure needed financing and
restructuring of the Company. Given the Company's lack of financial resources
during 2006, none of our remaining executive officers were granted annual
performance bonuses.

LONG-TERM INCENTIVES

     STOCK OPTIONS. The Compensation Committee views grants of stock options as
a major component of an executive's compensation, believing that the grant of
options aligns the interests of the executives with the interests of the
stockholders by providing a direct correlation between an increase in the value
of MacroChem's stock and executive compensation and that this method of
compensation allows MacroChem to conserve cash resources and retain key
personnel.

     In determining the size of a stock option award for an individual executive
officer, the Committee considers the same factors used for determining base
salary and applies each factor subjectively, without reference to specific
criteria. The Committee does not weigh any one factor more or less heavily than
any other and considers the input of the Chief Executive Officer and, as
necessary, outside experts, in reaching its determinations. The size of previous
option grants is not an important factor in determining current awards. Options
granted are exercisable at the market price on the date of the grant.

     RESTRICTED STOCK AWARDS. The Compensation Committee may make grants of
restricted stock to executive officers to provide additional long-term incentive
to build stockholder value. Restricted stock awards are made in anticipation of
contributions that will create value in the company and are subject to certain
vesting and other restrictions.

     In 2006, we awarded our chief executive officer a restricted stock grant
which vests when our common stock trades at or above $4.00 per share for thirty
consecutive trading days.

TRANSITION AGREEMENTS

     In addition to base salary and long-term incentive awards, a portion of the
compensation paid to our executive officers during 2006 was paid pursuant to
transition agreements. Because of insufficient capital resources, in August
2005, the Company discontinued its research and development activities and
terminated substantially all its non-management personnel. In addition, in
September 2005, the Company entered into transition agreements with each of its
executive officers to assure their availability to the Company during a period
of uncertainty and to reduce possible termination pay liability to these

                                      36

officers. These agreements terminated the then existing employment and severance
agreements with each of the executive officers. Because of improved prospects
for funding, the Company thereafter entered into amendments to the transition
agreements with Messrs. DeLuccia, Patriacca and Deegan, which provided that each
would remain employed by the Company until February, 2006 at a rate of pay equal
to one-half the base salary in effect for each executive prior to August 31,
2005. These transition agreements expired in February 2006, at which point we
entered into employment agreements with our executive officers as described
below.

EMPLOYMENT ARRANGEMENTS

EMPLOYMENT AGREEMENTS

     We entered into an employment agreement of indefinite length effective as
of February 13, 2006 with Robert J. DeLuccia. The agreement currently provides
for annual compensation of $288,000 and for the payment of nine months' salary
plus, if applicable, the continuation of medical, dental and group life
insurance benefits for up to nine months in the event he is terminated without
cause or twelve month's salary and bonus plus, if applicable, the continuation
of medical, dental and similar benefits for up to twelve months in the event he
is terminated as a result of a change of control. The agreement also provides
for a monthly automobile allowance of $1,500. In addition, the agreement
precludes Mr. DeLuccia from competing with the Company during his employment and
for a period of two years thereafter, and from disclosing confidential
information. Prior to entering into Mr. DeLuccia's current employment agreement,
we entered into a transition agreement with Mr. DeLuccia on September 16, 2005
which terminated his then existing employment agreement including the severance
pay provisions. The transition agreement, which originally provided that Mr.
DeLuccia would remain employed by the Company until November 30, 2005, was
subsequently amended to extend his employment through February 2006.

     We entered into an employment agreement of indefinite length effective as
of February 13, 2006 with Bernard Patriacca. The agreement currently provides
for annual base compensation of $200,000, and precludes Mr. Patriacca from
competing with the Company during his employment and for a period of two years
thereafter, and from disclosing confidential information. Prior to entering into
Mr. Patriacca's current employment agreements, we entered into a transition
agreement with Mr. Patriacca on September 12, 2005 which terminated his then
existing employment and severance agreements. The transition agreement, which
originally provided that Mr. Patriacca would remain employed by the Company
until November 30, 2005, was subsequently amended to extend his employment
through February 2006.

     We entered into an employment agreement of indefinite length effective as
of February 13, 2006 with Glenn E. Deegan. The agreement provided for annual
base compensation of $180,000, and precluded Mr. Deegan from competing with the
Company during his employment and for a period of two years thereafter, and from

- --------------------------------------------------------------------------------
(1)   Mr. DeLuccia was granted 75,000 shares of restricted common stock on
      February 10, 2006. Mr. DeLuccia is restricted from selling such shares
      until the price of our common stock is greater than or equal to $4.00 per
      share for a period of 30 consecutive trading days. No compensation charge
      was recognized as the vesting date is not certain.

                                       38


(2)   The options granted to Mr. DeLuccia were granted on February 10, 2006 at
      an exercise price of $1.62 per share. The options expire ten years from
      the date of grant and vest one third on the date of grant and one third on
      each grant date anniversary in 2007 and 2008.

(3)   The options granted to Mr. Patriacca were granted on February 10, 2006 at
      an exercise price of $1.62 per share. The options expire ten years from
      the date of grant and vest one third on the date of grant and one third on
      each grant date anniversary in 2007 and 2008.

(4)   The options granted to Mr. Deegan were granted on February 10, 2006 at an
      exercise price of $1.62 per share. The options were granted with an
      expiration date of ten years from the date of grant and provided that they
      would vest one third on the date of grant and one third on each grant date
      anniversary in 2007 and 2008. In connection with Mr. Deegan's departure
      from the Company on March 15, 2007, all unvested options were terminated.
      The terms of the options provide that in the event of a termination of
      employment other than for cause, the vested options will remain
      exercisable for six months following the termination date. The Board of
      Directors elected to extend Mr. Deegan's vested options for an additional
      six months in exchange for certain consulting services, and thus the
      100,000 remaining options expire on March 14, 2008.

(1)  The market value of the stock awards is determined by multiplying the number of shares times $0.45, which
     represents the per share closing price of our common stock as quoted on the OTC Bulletin Board(R) on December 29,
     2006, the last trading day of fiscal 2006.

(2)  Mr. DeLuccia was granted 75,000 shares of restricted common stock on February 10, 2006.  Mr. DeLuccia is restricted
     from selling such shares until the price of our common stock is greater than or equal to $4.00 per share for a
     period of 30 consecutive trading days.  See Note 4 to the Financial Statements included in our Annual Report on
     Form 10-K for the year ended December 31, 2006 for the relevant assumptions used to determine the value of the
     award.
(3)  Options vest over a three year period on each grant date anniversary.
(4)  Options were fully vested on the grant date.
(5)  Options vest one third on grant date and one third on each grant date anniversary.
(6)  Options were fully vested on the one year grant date anniversary.
(7)  Mr. Deegan resigned on March 15, 2007. The terms of the options provide that in the event of a termination of employment
     other than for cause, the vested options will remain exercisable for six months following the termination date. The Board of
     Directors elected to extend Mr. Deegan's vested options for an additional six months in exchange for certain consulting
     services, and thus the vested options expire on March 14, 2008.

OPTION EXERCISES AND STOCK VESTED

     There were no exercises of stock options or vesting of shares of restricted
stock held by the executive officers named in the Summary Compensation Table
during the fiscal year ended December 31, 2006.

PENSION BENEFITS

     We do not have any qualified or non-qualified defined benefits plans.

NONQUALIFIED DEFERRED COMPENSATION

     We do not have any non-qualified defined contribution plans or other
deferred compensation plans.

TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL ARRANGEMENTS

     Our executive officers are eligible to receive benefits under certain
conditions in accordance with each executive officer's employment or severance
agreement with us. We entered into separate Severance Agreements with each of
Messrs. Patriacca and Deegan on February 13, 2006. Each of the Severance
Agreements provides for the payment of six months' salary plus the continuation
of medical, dental and similar benefits for up to six months in the event the
executive is terminated without cause or nine month's salary and 75% of the
executive's bonus plus the continuation of medical, dental and similar benefits
for up to nine months in the event the executive is terminated in connection
with or following a change of control, as defined in the agreements and, in each
case, the agreements provide that all unvested options will become vested and
will be exercisable for the period of time set forth in the documents governing
the options. Our change of control arrangements with Mr. DeLuccia are contained
in his employment agreement with us and are summarized above under the heading
"Employment Arrangements."

     To determine the level of benefits provided under each of our executive
officer's severance agreements, data regarding peer practice, the circumstances
of the situation and impact on stockholders was considered. In each instance,
the severance benefit is constructed such that the benefit is discrete and
capped under a one-time payment limiting any potential on-going liability.

     The tables below reflect the amount of compensation to each of the named
executive officers of the Company in the event of termination of such
executive's employment. The amount of compensation payable to each executive
officer upon involuntary not-for-cause termination, termination following a
change of control and in the event of disability of the executive officer is
shown below. The amounts shown assume that each termination was effective as of
December 31, 2006 and thus are estimates of the amounts which would be paid out
to the executives upon their termination. The actual amounts to be paid out can
only be determined at the time of such executive's separation from the Company.
No compensation is paid in the event of voluntary termination. For the purposes
of the following tables, the term "Change in Control" refers to a
reorganization, merger, consolidation or similar transaction resulting in the
transfer of ownership of 50% of the Company's outstanding common stock or a sale
of substantially of all of the Company's assets and "Disability" is defined as
the employee's inability to continue to perform substantially all of his/her
duties and responsibilities.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

POLICIES AND PROCEDURES WITH RESPECT TO RELATED PARTY TRANSACTIONS

     The board of directors reviews and approves transactions between the
Company on the one hand and a related party, such as our directors, officers,
holders of more than five percent of our voting securities and their affiliates,
the immediate family members of any of the foregoing persons and any other
persons whom the board determined may be considered a related party, on the
other hand. Prior to board consideration of a transaction with a related party,
the material facts as to the related party's relationship or interest in the
transaction are disclosed to the board, and the transaction is not considered
approved by the board unless a majority of the directors who are not interested
in the transaction approve the transaction.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

     On December 23, 2005 and February 13, 2006, we issued an aggregate of 825.5
shares of our Series C Preferred Stock and warrants to purchase 7,861,900 shares
of our common stock in a private placement to institutional investors.

     SCO Capital Partners LLC acquired a total of 300 shares of our Series C
Preferred Stock and warrants to purchase 2,857,142 shares of our common stock
for an aggregate purchase price of $3,000,000, and Beach Capital LLC acquired a
total of 50 shares of our Series C Preferred Stock and warrants to purchase
47,620 shares of our common stock for an aggregate purchase price of $500,000.
In a subsequent transfer, SCO Capital Partners, L.P. purchased 9 shares of our
Series C Preferred Stock. Mr. Stephen S. Rouhandeh is the managing member of SCO
Capital Partners LLC, Beach Capital LLC and the entity that is the general
partner of SCO Capital Partners, L.P., and as such has sole dispositive and
voting power with respect to the shares owned by SCO Capital Partners LLC, Beach
Capital LLC and SCO Capital Partners, L.P. The Series C Preferred Stock and
warrants beneficially owned by Mr. Rouhandeh are convertible and exercisable
into approximately 71.71% of our common stock. In addition, for so long as 20%
of the Series C 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. On December 28, 2005, SCO Capital Partners LLC informed
us that the initial SCO director designees were Jeffrey B. Davis and Howard S.
Fischer, and our board of directors appointed them to our board on December 29,
2005.

     Mr. Rouhandeh is also the Chairman of SCO Securities LLC, which acted as
the placement agent in connection with the private placement and which acts as a
financial advisor to us for a monthly fee of $12,500. In exchange for its
services as placement agent, SCO Securities LLC received a fee equal to 7% of
the gross proceeds, or $577,850, and six-year warrants to purchase 786,189
shares of our common stock at an exercise price of $1.05 per share. SCO
Securities LLC assigned its warrants to the following four persons in the
amounts listed: (i) warrants to purchase 471,713 shares of common stock to SCO
Capital Partners LLC; (ii) warrants to purchase 157,238 shares of common stock
to Lake End Capital LLC, (iii) warrants to purchase 78,619 shares of common
stock to Mark Alvino and (iv) warrants to purchase 78,619 shares of common stock
to Howard Fischer. We also paid SCO Securities LLC $82,550 for out-of-pocket
expenses incurred in connection with the transaction.

     Mr. Jeffrey Davis, who was elected to our Board of Directors on
December 29, 2005 as the designee of SCO Capital Partners LLC, is the managing
member of Lake End Capital LLC, an entity which purchased 50 shares of our
Series C Preferred Stock and warrants to purchase 476,190 shares of our common
stock for an aggregate purchase price of $500,000. As noted above, Lake End
Capital LLC also received warrants to purchase an additional 157,238 shares of
our common stock as a designee of SCO Securities LLC, the placement agent in our
recent private placement. Mr. Davis is the President of SCO Securities LLC.
Subject to conversion and exercise restrictions on the securities held by Lake

                                       45

End Capital LLC as described below under the heading "Beneficial Ownership of
Voting Securities", the Series C Preferred Stock and warrants beneficially owned
by Mr. Davis are convertible and exercisable into 4.95% of our common stock.

     Mr. Howard S. Fischer, who was elected to our Board of Directors on
December 29, 2005 as the designee of SCO Capital Partners LLC, is a Managing
Director of SCO Securities LLC. As noted above, Mr. Fischer received warrants to
purchase 78,619 shares of our common stock as a designee of SCO Securities LLC.

     Mr. Mark Alvino, who is a nominee for election to our Board of Directors at
the annual meeting to which this proxy statement relates, has been designated by
SCO Capital Partners LLC, and is a Managing Director of SCO Securities LLC. As
noted above, Mr. Alvino received warrants to purchase 78,619 shares of our
common stock as a designee of SCO Securities LLC.

                    BENEFICIAL OWNERSHIP OF VOTING SECURITIES

     The following table sets forth, as of March 30, 2007 (except as noted),
information concerning ownership of our voting securities by (1) each person
known by us to be the beneficial owner of more than five percent (5%) of our
voting securities, (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
2,849,534 shares of our common stock, and 781.5 shares of our Series C Preferred
Stock, outstanding on March 30, 2007.

     In a private placement to institutional investors closing in part on
December 23, 2005 and in part on February 13, 2006, we issued an aggregate of
825.5 shares of our Series C Cumulative Convertible Preferred Stock and warrants
to purchase 7,861,912 shares of our common stock for approximately $8,255,000 in
gross proceeds ($7,312,851 net of issuance costs). The Series C 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, SCO CAPITAL PARTNERS L.P. 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%. As of March 30, 2007, giving effect to the beneficial ownership cap
restrictions, the Series C Preferred Stock acquired by the investors is
convertible into 4,967,920 shares of common stock and the holders of the Series
C Preferred Stock vote on an as-converted basis with the holders of our common
stock, and therefore hold approximately 63.5% of the voting power of our
outstanding securities. Consequently, the private placement resulted in a change
of control of the Company. Assuming both the conversion of the Series C
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 84.9% of the outstanding
common stock of the Company. In addition, for so long as 20% of the Series C
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. For 2007, SCO Capital
Partners LLC has designated Jeffrey B. Davis and Mark J. Alvino as its nominees,
and thus Howard S. Fischer is not standing for re-election this year.

     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 30, 2007 through the exercise of any stock option,
warrant or other right. The inclusion in the following table of those shares,

                                       46

however, does not constitute an admission that the named stockholder is a direct
or indirect beneficial owner.

                            SELLING SECURITY HOLDERS

     On December 23, 2005, we entered into a securities purchase agreement with
SCO Capital Partners LLC and Lake End Capital LLC, and on February 13, 2006, in
connection with a subsequent closing under the purchase agreement, we amended
and restated the purchase agreement and additional institutional investors
became party to the agreement. Under the securities purchase agreement, we
issued the following securities in exchange for total cash consideration of
$8,255,000:

     o    a total of 825.5 shares of our Series C Cumulative Convertible
          Preferred Stock; and

     o    six-year warrants to purchase 7,861,912 shares of common stock at an
          exercise price of $1.26.

     The Series C Cumulative Convertible 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 Cumulative 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 either elected
otherwise prior to the purchase of such preferred stock or elects otherwise upon
not less than 61 days prior written notice, 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 pursuant to a beneficial
ownership cap 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 beneficial
ownership cap restriction on their exercise. SCO Capital Partners LLC, Beach
Capital LLC and Perceptive Life Sciences Master Fund Ltd., or 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 Cumulative Convertible Preferred Stock will be subject to a
beneficial ownership cap of 9.95% instead of 4.95%.

     SCO Securities LLC, an affiliate of SCO Capital Partners LLC, acted as
placement agent in connection with the private placement. For its services as
placement agent, we paid SCO Securities LLC a fee equal to 7% of the gross
proceeds, or $577,850, and issued six-year warrants to purchase 786,189 shares
of our common stock at an exercise price of $1.05 per share. The terms of the
placement agent warrants are the same as the terms of the warrants issued to the
Purchasers except that the exercise price of the warrant issued to the placement
agent is $1.05. SCO Securities LLC allocated the placement agent warrants to the
following four persons in the amounts listed: (i) warrants to purchase 471,713
shares of common stock to SCO Capital Partners LLC; (ii) warrants to purchase
157,238 shares of common stock to Lake End Capital LLC, (iii) warrants to
purchase 78,619 shares of common stock to Mark Alvino and (iv) warrants to
purchase 78,619 shares of common stock to Howard Fischer. We also paid SCO
Securities LLC $82,550 for out-of-pocket expenses incurred in connection with
the transaction and agreed to pay all reasonable expenses of the Purchasers
incurred in connection with the private placement.

     Pursuant to the securities purchase agreement and a registration rights
agreement with each of the selling stockholders, we are filing a registration
statement, of which this prospectus forms a part, in order to permit those
stockholders to resell to the public the shares of common stock that they may
acquire upon conversion of the Series C Cumulative Convertible Preferred Stock
that they purchased pursuant to the securities purchase agreement and the shares
of common stock that they may acquire upon any exercise of the warrants. We are
registering the number of shares required under the securities purchase
agreement and registration rights agreement, which number is based upon the
total number of shares of common stock into which the Series C Cumulative
Convertible Preferred Stock is convertible, determined without giving effect to
the conversion restriction described above, the number of shares issuable upon
any exercise of the warrants issued to the purchasers, determined without giving
effect to the exercise restriction described above, and the number of shares
issuable upon any exercise of the warrants issued to the placement agent or its
designees in connection with the private placement, determined without giving
effect to the exercise restriction described above.

                                       49


     The following table sets forth information regarding beneficial ownership
of our common stock by the selling stockholders as of March 30, 2007. While all
the shares that are issuable to a selling shareholder upon the conversion of the
Series C Cumulative Convertible Preferred Stock and exercise of the warrants are
included in the number of shares being offered in the table, shares which a
selling security holder is prevented from acquiring as a result of the
beneficial ownership cap described above are not shown as beneficially owned.
Because the selling stockholders may offer all or some portion of the common
stock listed in the table pursuant to this prospectus or otherwise, no estimate
can be given as to the amount or percentage of common stock that will be held by
the selling stockholders upon termination of the offering. The selling
stockholders may sell all, part, or none of the shares listed. The shares listed
in the table do not include the shares of common stock that may be paid as a
dividend on outstanding shares of Series C Cumulative Convertible Preferred
Stock. In computing the number of shares beneficially owned by a person and the
percentage ownership of that person, all shares of common stock underlying
shares of Series C Cumulative Convertible Preferred Stock and warrants held or
beneficially owned by that person are included. Those shares, however, are not
deemed outstanding for the purpose of computing the percentage ownership of any
other person. Each stockholder's percentage ownership shown in the table is
based on 2,849,534 shares of common stock issued and outstanding on March 30,
2007.

     None of the selling stockholders has had any position, office or other
material relationship with us within the past three years, except as set forth
below and except that SCO Securities LLC, an affiliate of SCO Capital Partners
LLC, acted as the placement agent for the private placement of our Series C
Cumulative Convertible Preferred Stock and acts as a financial advisor to us.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL MATTERS

     Our certificate of incorporation authorizes us to issue 100,000,000 shares
of common stock, par value $0.01 per share, and 6,000,000 shares of preferred
stock, par value $0.01 per share, of which 500,000 shares are designated as
Series A Convertible Preferred Stock, 600,000 shares are designated as Series B
Preferred Stock and 1,500 shares are designated Series C Cumulative Convertible
Preferred Stock. As of March 30, 2007, we had 2,849,534 shares of common stock,
no shares of Series A Convertible Preferred Stock, no shares of Series B
Preferred Stock and 781.50 shares of Series C Cumulative Convertible Preferred
Stock issued and outstanding. Our certificate of incorporation authorizes our
Board of Directors, without stockholder approval, to issue preferred stock in
series and with such voting rights, designations, preferences, limitations and
special rights as may be designated by the Board of Directors from time to time.

     We are registering shares of our common stock under the registration
statement of which this prospectus is a part. The following is a summary
description of our outstanding capital stock and is qualified in its entirety by
reference to our certificate of incorporation and bylaws, which are exhibits to
the registration statement of which this prospectus is a part.

COMMON STOCK

     Subject to the rights and preferences of holders of our preferred stock,
holders of shares of our common stock are entitled to receive dividends, as and
to the extent dividends may be declared by our Board of Directors, out of funds
legally available therefore. In the event of our liquidation, dissolution or
winding up, holders of shares of our common stock are entitled to share ratably
in all assets remaining after payment of liabilities and preferences to holders
of our preferred stock. Holders of shares of our common stock are entitled to
one vote per share on all matters on which stockholders are entitled to vote.
The holders of a majority of the outstanding shares of our common stock entitled
to vote constitute a quorum for taking action by the stockholders. Except for
matters where a higher vote is required by law, the affirmative vote of the
holders of shares of our common stock present or represented and entitled to
vote is required to take any such action. Holders of shares of our common stock
have no preemptive, conversion or other subscription rights. There are no
redemption, sinking fund or call provisions applicable to our common stock.

SERIES C CUMULATIVE CONVERTIBLE PREFERRED STOCK

     The holders of the Series C Cumulative Convertible Preferred Stock are
entitled to receive cumulative dividends, based on the $10,000 liquidation
preference per share, at a rate of 10% per share per annum payable quarterly in
arrears on March 31, June 30, September 30 and December 31 of each year,
commencing on March 31, 2006. The dividend rate is subject to increase to 14%
upon the occurrence of certain events. The cumulative dividends may be paid at
our option in either cash or in shares of our common stock.

     The Series C Cumulative Convertible Preferred Stock ranks senior to our
Series A Convertible Preferred Stock, our Series B Convertible Preferred Stock
and our common stock with respect to any distribution of assets upon our
liquidation. In the event of our liquidation, holders of our Series C Cumulative
Convertible Preferred Stock are entitled, after payment of our creditors, to
receive a distribution prior in preference to any holder of our Series A
Convertible Preferred Stock, our Series B Convertible Preferred Stock and our
common stock of an amount per share equal to the greater of $10,000 per share of
Series C Cumulative Convertible Preferred Stock, together with unpaid and
accrued dividends (whether or not earned or declared), or the amount per share
that a holder of Series C Cumulative Convertible Preferred Stock would have
received if that holder had converted such Series C Cumulative Convertible
Preferred Stock to shares of our common stock immediately prior to the
occurrence of the event giving rise to the distribution. In the event the assets
available to be distributed to the holders of our Series C Cumulative
Convertible Preferred Stock are insufficient to pay the full preferential amount
due such holders, the available assets will be distributed pro rata to the
holders of Series C Cumulative Convertible Preferred Stock. In the event the
assets available to be distributed to our stockholders exceed the amount
necessary to pay the full preferential amount due to the Series C Cumulative
Convertible Preferred Stock, then that excess will be distributed pro rata to



                                       54


the holders of our common stock and Series C Cumulative Convertible Preferred
Stock, determined on an as-if-converted to common stock basis.

     In the event we offer equity securities or securities convertible into
equity securities in the future, each holder of our Series C Cumulative
Convertible Preferred Stock may elect to purchase, on the same terms and
conditions in which we offer those securities to other purchasers, up to that
portion of the securities that we propose to offer that equals the proportion
that the number of shares of common stock that such holder owns, or has a right
to acquire, bears to the total number of shares of common stock then outstanding
(determined assuming the full conversion and exercise of all convertible and
exercisable securities then outstanding). This participation right does not
apply to (1) the conversion of the Series C Cumulative Convertible Preferred
Stock, the exercise of warrants issued in connection with the Series C
Cumulative Convertible Preferred Stock or the issuance of common stock as
payment of dividends on the Series C Cumulative Convertible Preferred Stock, (2)
the exercise of any warrants or options outstanding as of December 23, 2005, (3)
the issuance of common stock, stock awards or stock options under, or granted
pursuant to, any stock-based compensation plans, (4) the issuance of shares of
common stock pursuant to a stock split, combination or subdivision of the
outstanding shares of common stock, (5) the issuance of shares of common stock
or their equivalents in connection with a bona-fide board-approved strategic
transaction, where the primary purpose is not to provide financing to us, or (6)
the issuance of additional shares of Series C Cumulative Convertible Preferred
Stock and warrants to purchase common stock issued under the purchase agreement
pursuant to which the Series C Cumulative Convertible Preferred Stock and
warrants were sold.

     Except as provided by law, holders of our Series C Cumulative Convertible
Preferred Stock generally vote together with our common stock as a single class
on an as-if-converted to common stock basis and, subject to the ownership
restriction described below, have full voting rights and powers equal to the
voting rights and powers of holders of common stock. Holders of Series C
Cumulative Convertible Preferred Stock are restricted from (i) converting Series
C Cumulative Convertible Preferred Stock into common stock to the extent that
such conversion would result in the holder owning more than 4.95% of our issued
and outstanding common stock or (ii) 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. Holders of Series C Cumulative Convertible
Preferred Stock may elect, subject to certain conditions, including not less
than 61 days prior written notice, to be exempt from this beneficial ownership
cap. The approval of holders of 75% of the outstanding shares of our Series C
Cumulative Convertible Preferred Stock, however, is required to (1) change the
rights, preferences or privileges of the Series C Cumulative Convertible
Preferred Stock, (2) create any new class of preferred stock or increase the
authorized number of shares of any class of preferred stock ranking senior to
the Series C Cumulative Convertible Preferred Stock, (3) redeem any class of our
capital stock, other than the Series C Cumulative Convertible Preferred Stock,
(4) issue any shares of the Series A Convertible Preferred Stock or (4) declare
the payment of a distribution other than a dividend or distribution paid
according to the terms of the Series C Cumulative Convertible Preferred Stock.

     Shares of our Series C Cumulative Convertible Preferred Stock are
convertible, at the option of the holder, at any time into shares of common
stock. The number of shares of common stock into which each share of Series C
Cumulative Convertible Preferred Stock is convertible is determined by dividing
the liquidation value per share plus all accrued and unpaid dividends thereon by
the then current conversion price. As of March 30, 2007, the conversion price is
$1.05.

     If we fail or refuse to convert any shares of Series C Cumulative
Convertible Preferred Stock in accordance with the terms of the Series C
Cumulative Convertible Preferred Stock, the holders of our Series C Cumulative
Convertible Preferred Stock are entitled to elect to require us to redeem their
Series C Cumulative Convertible Preferred Stock. In the event of a redemption,
the price that we are required to pay to redeem a share of Series C Cumulative
Convertible Preferred Stock is an amount in cash equal to the greater of (1) all
accrued but unpaid dividends as of the date the holder makes the demand for
redemption with respect to each share to be redeemed plus the $10,000
liquidation preference per share or (2) the total number of shares of common
stock into which such Series C Cumulative Convertible Preferred Stock is
convertible multiplied by the then-current market price of the common stock.

     In the event we issue additional shares of common stock (other than (1)
upon conversion of shares of Series C Cumulative Convertible Preferred Stock,
(2) to certain individuals pursuant to an employee stock incentive plan or
written agreement approved by our board of directors (3) as a dividend or
distribution on our Series C Cumulative Convertible Preferred Stock, (4) as part


                                       55


of a stock split, combination or subdivision of outstanding shares of common
stock or (5) additional shares of Series C Cumulative Convertible Preferred
Stock issued at additional closings under the same purchase agreement issuing
the current outstanding Series C Cumulative Convertible Preferred Stock) at a
price per share that is less than the conversion value of the Series C
Cumulative Convertible Preferred Stock in effect immediately prior to the
issuance of the additional shares of common stock, then we will adjust the
conversion price of our Series C Cumulative Convertible Preferred Stock to be
equal to the price per share at which the additional shares are issued.

     Subject to certain restrictions, the terms of the Series C Cumulative
Convertible Preferred Stock provide that we may, at our option, cause all of the
outstanding shares of Series C Cumulative Convertible Preferred Stock to be
converted into shares of common stock if there is an effective registration
statement under the Securities Act covering the common stock into which the
Series C Cumulative Convertible Stock is convertible and if the daily market
price of our common stock is at least ten times the then current exercise price
per share and has been at or above such price per share for thirty consecutive
trading days and the volume of common stock traded on the applicable stock
exchange on each trading day is not less than 100,000 shares.

STOCKHOLDER RIGHTS PLAN

     The holders of our common stock have rights (the "rights") under a
stockholder rights plan which was adopted by our Board of Directors on August
13, 1999, and which was amended on December 23, 2005. The rights, which entitle
their holder to purchase a fractional share of a new class of preferred stock
for each share of our common stock owned by the holder, attach to all
certificates representing shares of our common stock outstanding at the close of
business on August 13, 1999 and attach to any shares of common stock issued by
us after August 13, 1999 and prior to the date the rights separate from the
common stock certificates, as described in the following sentence. The rights
will separate from the common stock and rights certificates will be issued on
the earlier of (1) the tenth business day following the later of the date of a
public announcement that a person, including its affiliates or associates (an
"Acquiring Person"), except as described below, has acquired or obtained the
right to acquire, beneficial ownership of 20% or more of our outstanding shares
of common stock or the date on which any of our executive officers has actual
knowledge that a person became an Acquiring Person or (2) the tenth business day
following commencement of a tender offer or exchange offer that would result in
any person or its affiliates and associates owning 20% or more of our
outstanding common stock. Until a right is exercised, it does not give the
holder thereof any rights as a stockholder, including, without limitation, the
right to vote or to receive dividends.

     If any person or group of affiliated or associated persons (other than us
or our affiliates) shall become an Acquiring Person, each holder of a right will
have the right to receive shares of our common stock (or, in certain
circumstances, cash, property or other MacroChem securities) having a market
value of two times the exercise price of the right. Also, in the event that we
are acquired in a merger or other business combination, or more than 25% of our
assets or earning power is sold, each holder of a right would have the right to
exercise their right and thereby receive common stock of the acquiring company
with a market value of two times the exercise price of the right. Following the
occurrence of any of the events described in this paragraph, any rights that
are, or (under certain circumstances specified in the stockholder rights plan)
were, beneficially owned by any Acquiring Person shall immediately become null
and void.

     Our Board of Directors may, at its option, at any time after any person
becomes an Acquiring Person, exchange all or part of the then outstanding and
exercisable rights for shares of our common stock at an exchange ratio of one
share of common stock per right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after August 13, 1999.
Our Board of Directors, however, may not effect an exchange at any time after
any person (other than (1) us, (2) any subsidiary of ours, (3) any employee
benefit plan of ours or (4) any entity holding common stock for or pursuant to
the terms of any employee benefit plan of ours), together with all its
affiliates, becomes the beneficial owner of 50% or more of our outstanding
common stock. Immediately upon the action of our Board of Directors ordering the
exchange of any rights and without any further action and without any notice,
the right of a holder to exercise its rights will terminate and a holder of
rights will be entitled to receive only that number of shares of common stock
equal to the number of rights held by the holder multiplied by the appropriate
exchange ratio.


                                       56


     The exercise price of the rights, and the number of one one-hundredths of a
share of preferred stock or other securities or property issuable upon exercise
of the rights are subject to adjustment from time to time to prevent dilution
(1) in the event of a stock dividend on, or a subdivision, combination or
reclassification of, the preferred stock, (2) upon the grant to holders of the
preferred stock of certain rights or warrants to subscribe for shares of the
preferred stock or convertible securities at less than the current market price
of the preferred stock or (3) upon the distribution to holders of the preferred
stock of evidences of indebtedness or assets (excluding cash dividends paid out
of our earnings or retained earnings and certain other distributions) or of
subscription rights or warrants (other than those referred to above).

     At any time prior to the close of business on August 13, 2009 or the
earlier redemption of the rights, our Board of Directors, by majority vote, may
redeem the rights at a redemption price of $0.01 per right, as described in the
stockholder rights plan. The stockholder rights plan may be amended by our Board
of Directors at any time prior to the date on which the rights separate from the
common stock without the approval of the holders of the rights. From and after
the date of separation, the stockholder rights plan may be amended by our Board
of Directors without the approval of the holders of the rights in order to cure
any ambiguity, to correct any defective or inconsistent provisions, to change
any time period for redemption or any other time period under the stockholder
rights plan or to make any other changes that do not adversely affect the
interests of the holders of the rights (other than any Acquiring Person or its
affiliates and associates, or their transferees).

     On December 23, 2005, the stockholder rights plan was amended to provide
that the acquisition of our Series C Cumulative Convertible Preferred Stock and
warrants to acquire shares of our common stock by the selling security holders
pursuant to the securities purchase agreement, and any subsequent acquisition by
them of common stock upon the conversion or exercise of those securities, would
not result in the selling security holders becoming Acquiring Persons and would
not trigger the separation of the rights from the common stock.

     The foregoing description of the rights does not purport to be complete and
is qualified in its entirety by reference to the stockholder rights plan, a copy
of which is an exhibit to the registration statement of which this prospectus is
a part. The stockholder rights plan could make it more difficult, and therefore
discourage attempts, to acquire control of us.

OTHER PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS

     ADVANCED NOTICE PROCEDURES FOR STOCKHOLDER PROPOSALS. Our bylaws establish
an advance notice procedure for stockholder proposals to be brought before an
annual meeting of our stockholders, including proposed nominations of persons
for election to our board. Stockholders at our annual meeting may consider only
proposals or nominations specified in the notice of meeting or brought before
the meeting by or at the direction of our board or by a stockholder who was a
stockholder of record on the record date for the meeting, who is entitled to
vote at the meeting and who has given our secretary timely written notice, in
proper form, of the stockholder's intention to bring that business before the
meeting. Although our bylaws do not give our board the power to approve or
disapprove stockholder nominations of candidates or proposals regarding other
business to be conducted at a special or annual meeting, our bylaws may have the
effect of precluding the conduct of some business at a meeting if the proper
procedures are not followed or may discourage or defer a potential acquirer from
conducting a solicitation of proxies to elect its own slate of directors or
otherwise attempting to obtain control of us.

PROVISIONS OF DELAWARE LAW GOVERNING BUSINESS COMBINATIONS

     We are subject to the "business combination" provisions of the Delaware
General Corporation Law. In general, such provisions prohibit a publicly-held
Delaware corporation from engaging in any "business combination" transactions
with any "interested stockholder" for a period of three years after the date on
which the person became an "interested stockholder," unless:

     o    prior to such date, the Board of Directors approved either the
          "business combination" or the transaction which resulted in the
          "interested stockholder" obtaining such status;

     o    upon consummation of the transaction which resulted in the stockholder
          becoming an "interested stockholder," the "interested stockholder"
          owned at least 85% of the voting stock of the corporation outstanding



                                       57


          at the time the transaction commenced, excluding for purposes of
          determining the voting stock outstanding (but not the outstanding
          voting stock owned by the "interested stockholder") those shares owned
          by (a) persons who are directors and also officers and (b) employee
          stock plans in which employee participants do not have the right to
          determine confidentially whether shares held subject to the plan will
          be tendered in a tender or exchange offer; or

     o    at or subsequent to such time the "business combination" is approved
          by the Board of Directors and authorized at an annual or special
          meeting of stockholders, and not by written consent, by the
          affirmative vote of at least 66?% of the outstanding voting stock
          which is not owned by the "interested stockholder."

     A "business combination" is defined to include mergers, asset sales and
other transactions resulting in financial benefit to a stockholder. In general,
an "interested stockholder" is a person who, together with affiliates and
associates, owns 15% or more of a corporation's voting stock or within three
years did own 15% or more of a corporation's voting stock. The statute could
prohibit or delay mergers or other takeover or change in control attempts with
respect to us and, accordingly, may discourage attempts to acquire us.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company.

                              PLAN OF DISTRIBUTION

     We are registering the shares of common stock on behalf of the selling
security holders. Sales of shares may be made by selling security holders,
including their respective donees, transferees, pledgees or other
successors-in-interest directly to purchasers or to or through underwriters,
broker-dealers or through agents. Sales may be made from time to time on the OTC
Bulletin Board, any other exchange or market upon which our shares may trade in
the future, in the over-the-counter market or otherwise, at market prices
prevailing at the time of sale, at prices related to market prices, or at
negotiated or fixed prices. The shares may be sold by one or more of, or a
combination of, the following:

     o    a block trade in which the broker-dealer so engaged will attempt to
          sell the shares as agent but may position and resell a portion of the
          block as principal to facilitate the transaction (including crosses in
          which the same broker acts as agent for both sides of the
          transaction);

     o    purchases by a broker-dealer as principal and resale by such
          broker-dealer, including resales for its account, pursuant to this
          prospectus;

     o    ordinary brokerage transactions and transactions in which the broker
          solicits purchases;

     o    through options, swaps or derivatives;

     o    in privately negotiated transactions;

     o    in making short sales or in transactions to cover short sales; and

     o    put or call option transactions relating to the shares.

     The selling security holders may effect these transactions by selling
shares directly to purchasers or to or through broker-dealers, which may act as
agents or principals. These broker-dealers may receive compensation in the form
of discounts, concessions or commissions from the selling security holders
and/or the purchasers of shares for whom such broker-dealers may act as agents
or to whom they sell as principals, or both (which compensation as to a
particular broker-dealer might be in excess of customary commissions). The
selling security holders have advised us that they have not entered into any
agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their securities.


                                       58


     The selling security holders may enter into hedging transactions with
broker-dealers or other financial institutions. In connection with those
transactions, the broker-dealers or other financial institutions may engage in
short sales of the shares or of securities convertible into or exchangeable for
the shares in the course of hedging positions they assume with the selling
security holders. The selling security holders may also enter into options or
other transactions with broker-dealers or other financial institutions which
require the delivery of shares offered by this prospectus to those
broker-dealers or other financial institutions. The broker-dealer or other
financial institution may then resell the shares pursuant to this prospectus (as
amended or supplemented, if required by applicable law, to reflect those
transactions).

     The selling security holders and any broker-dealers that act in connection
with the sale of shares may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act of 1933, and any commissions received by
broker-dealers or any profit on the resale of the shares sold by them while
acting as principals may be deemed to be underwriting discounts or commissions
under the Securities Act. The selling security holders may agree to indemnify
any agent, dealer or broker-dealer that participates in transactions involving
sales of the shares against liabilities, including liabilities arising under the
Securities Act. We have agreed to indemnify each of the selling security holders
and each selling security holder has agreed, severally and not jointly, to
indemnify us against some liabilities in connection with the offering of the
shares, including liabilities arising under the Securities Act.

     The selling security holders will be subject to the prospectus delivery
requirements of the Securities Act. We have informed the selling security
holders that the anti-manipulative provisions of Regulation M promulgated under
the Securities Exchange Act of 1934 may apply to their sales in the market.

     Selling security holders also may resell all or a portion of the shares in
open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of Rule 144.

     Upon being notified by a selling security holder that a material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, we will file a supplement to
this prospectus, if required pursuant to Rule 424(b) under the Securities Act,
disclosing:

     o    the name of each such selling security holder and of the participating
          broker-dealer(s);

     o    the number of shares involved;

     o    the initial price at which the shares were sold;

     o    the commissions paid or discounts or concessions allowed to the
          broker-dealer(s), where applicable;

     o    that such broker-dealer(s) did not conduct any investigation to verify
          the information set out or incorporated by reference in this
          prospectus; and

     o    other facts material to the transactions.

     In addition, if required under applicable law or the rules or regulations
of the Commission, we will file a supplement to this prospectus when a selling
security holder notifies us that a donee or pledgee intends to sell more than
500 shares of common stock.

     We are paying all expenses and fees in connection with the registration of
the shares. The selling security holders will bear all brokerage or underwriting
discounts or commissions paid to broker-dealers in connection with the sale of
the shares.

                                     EXPERTS

     The financial statements for the years ended December 31, 2005 and December
31, 2006 appearing in this prospectus have been audited by Vitale, Caturano &
Company, Ltd., an independent registered public accounting firm, as stated in
their report appearing elsewhere herein, and are included in reliance upon the
report of such firm given upon their authority as experts in accounting and
auditing.

     The financial statements for the year ended December 31, 2004 included in
this prospectus have been audited by Deloitte & Touche LLP, an independent
registered public accounting firm, as stated in their report appearing herein
and elsewhere in the registration statement (which report expresses an
unqualified opinion on the financial statements and includes an explanatory
paragraph relating to the Company's ability to continue as a going concern), and
have been so included in reliance upon the report of such firm given upon their
authority as experts in accounting and auditing.

         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.

     During the Company's fiscal year ended 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
report for such period. During the Company's fiscal year ended 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

             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, 2006 and 2005, and the related statements of
operations, stockholders' equity, and cash flows for the years then ended. 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 audits 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 audits 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 audits provide a
reasonable basis for our opinion.

In our opinion, the accompanying financial statements referred to above present
fairly, in all material respects, the financial position of the Company as of
December 31, 2006 and 2005, and the results of its operations and its cash flows
for the years then ended in conformity with accounting principles generally
accepted in the United States of America.

As discussed in Note 1 to the consolidated financial statements, the Company
adopted the provisions of Statement of Financial Accounting Standard No. 123(R),
"Share-Based Payment," effective January 1, 2006.

             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, 2004, and the related statements of operations,
stockholders' equity, and cash flows for the year then ended. 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. 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 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, 2004, and the
results of their operations and their cash flows for the year 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 to 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 losses from operations every year since
its inception and the Company anticipates that operating losses may continue for
the foreseeable future. At December 31, 2006 and 2005, the Company's accumulated
deficit was approximately $81.4 million and $82.6 million, respectively . 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, cash equivalents and short-term investments
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.

     The year end December 31, 2005 balance sheet has been restated to reflect
the changes in the accounting for the Series C Cumulative Preferred Stock
Offering (Note 5). In connection with the offering, the Company issued warrants
to the private placement agent for services rendered. The fair value of the
award was originally accounted for as an offset to the proceeds of the Series C
Preferred offering and a credit to additional paid in capital. Upon further
review of the terms of the warrants, it was determined that the private
placement agent's warrants' put feature enables the holder, at their option, to
require the Company to repurchase the award for cash in the event of a change in
control. The Company determined that the warrants meet the definition of a
derivative investment as defined in SFAS 133, "Accounting for Derivative
Financial Instruments Indexed to, and Potentially Settled in, a Company's Own
Stock," and should be adjusted to its current fair value at each reporting
period and classified as a warrant liability. As such, the Balance Sheet has
been adjusted to reflect a reclass of $174,922 from additional paid in capital
to warrant liability. There was no impact on the Statement of Operations or the
Statement of Cash Flows for the year ended December 31, 2005. As a result of the
error, each of the quarters ended March 31, June 30 and September 30, 2006 have
been restated. (See Note 9.)

     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(R). Management bases its estimates on certain assumptions, which it believes
are reasonable in the circumstances, and while actual results could differ from
those estimates, management does not believe that any change in those
assumptions in the near term would have a significant effect on the financial
position or the results of operations.

     FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying amounts of cash, cash
equivalents, short-term investments, accounts payable and accrued expenses
approximate their fair value because of their short-term nature.

                                      F-8


     CONCENTRATION OF RISK - Cash, cash equivalents and short-term investments
at December 31, 2006 and 2005 are primarily comprised of 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 liquid certificates of
deposit with a carrying value of $4,157,038 at December 31, 2006 and $0 in 2005.

     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 $376,228 and $324,008, respectively, at
December 31, 2006 and 2005. 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 2004 in which Topiglan did not
meet its primary clinical endpoints, the Company recorded a reduction of
$124,853 to the carrying value of certain patent assets related to Topiglan.

     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 - ADOPTION OF SFAS 123(R)

     Prior to January 1, 2006, the Company accounted for stock-based
compensation issued to employees using the intrinsic value method, which follows
the recognition and measurement principles of Accounting Principles Board
("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and
Financial Accounting Standards Board ("FASB") Interpretation ("FIN") No. 44,
"Accounting for Certain Transactions Involving Stock Compensation." Generally,
no stock-based employee compensation cost related to stock options was reflected
in net income, as all options granted under stock-based compensation plans had
an exercise price equal to the market value of the underlying common stock on
the grant date. Compensation cost related to restricted stock units granted to
non-employee directors and certain key employees was reflected as an expense as
services were rendered.

     On January 1, 2006, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 123(R), "Share-Based Payment," using the modified
prospective method, which requires measurement of compensation cost for all
stock awards at fair value on the date of grant and recognition of compensation
over the requisite service period for awards expected to vest. The fair value of
stock options is estimated using the Black-Scholes valuation model, and the fair
value of restricted stock units is determined based on the number of shares
granted and the quoted price of the Company's common stock on the date of grant.
Such value is recognized as expense over the requisite service period, net of
estimated forfeitures, using the straight-line attribution method. The estimate
of awards that will ultimately vest requires significant judgment, and to the
extent actual results or updated estimates differ from the Company's current
estimates, such amounts will be recorded as a cumulative adjustment in the

                                      F-9


period estimates are revised. The Company considers many factors when estimating
expected forfeitures, including types of awards, employee class and historical
employee attrition rates. Actual results, and future changes in estimates, may
differ substantially from the Company's current estimates.

     Stock based compensation expense for the years ended December 31, 2006,
2005 and 2004 is as follows:

     On November 10, 2005, the Financial Accounting Standards Board ("FASB")
issued FASB Staff Position SFAS 123(R)-3 "Transition Election Related to
Accounting for Tax Effects of Share-Based Payment Awards." The Company has
elected to adopt the alternative transition method provided the FASB Staff
Position for calculating the tax effects (if any) of stock-based compensation
expense pursuant to SFAS 123(R). The alternative transition method includes
simplified methods to establish the beginning balance of the additional paid-in
capital pool related to the tax effects of employee stock-based compensation,
and to determine the subsequent impact to the additional paid-in capital pool
and the consolidated statements of operations and cash flows of the tax effects
of employee stock-based compensation awards that are outstanding upon adoption
of SFAS 123(R).

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

     BASIC AND DILUTED INCOME OR (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 for the year ended December 31,
2006 reflect the effect of the Company's outstanding Series C Convertible
Preferred shares, options and warrants, except where such items would be
anti-dilutive. For the years ended December 31, 2005 and 2004, 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 from stock options and warrants not included in per share calculations
under the treasury stock method for 2006, 2005 and 2004 were 9,769,170,
2,807,673 and 155,919 shares, respectively.

     RECENT ACCOUNTING PRONOUNCEMENT - In June 2006, the FASB issued FASB
Interpretation 48, "Accounting for Uncertainty in Income Taxes, an
Interpretation of FASB Statement No. 109" ("FIN 48"), which clarifies the
accounting for uncertainty in income taxes recognized in a company's financial
statements in accordance with SFAS 109 "Accounting for Income Taxes." FIN 48
prescribes a recognition threshold and measurement attribute for the financial
statement recognition and measurement of a tax position taken or expected to be
taken in a tax return. FIN 48 becomes effective for fiscal years beginning after
December 15, 2006. The Company does not expect the adoption of FIN 48 to have a
material impact on its financial position or results of operations.

     In September 2006, the FASB issued Statement 157 "Fair Value Measurements"
("SFAS 157"), which establishes a framework for measuring fair value in
generally accepted accounting principles and expands disclosures about fair
value financial instruments. SFAS 157 becomes effective for fiscal years
beginning after November 15, 2007. The Company will adopt this statement
prospectively once it is effective and applicable. The Company does not expect
SFAS 157 to have a material impact on its financial position or results of
operations.

     In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for
Financial Assets and Financial Liabilities ("SFAS 159"). SFAS 159 provides
companies with an option to report selected financial assets and liabilities at
fair value. SFAS 159 also establishes presentation and disclosure requirements
designed to facilitate comparisons between companies that choose different
measurement attributes for similar types of assets and liabilities and to
provide additional information that will help investors and other financial
statement users to more easily understand the effect of the company's choice to
use fair value on its earnings. Finally, SFAS 159 requires entities to display
the fair value of those assets and liabilities for which the company has chosen
to use fair value on the face of the balance sheet. SFAS 159 is effective as of
the beginning of an entity's first fiscal year beginning after November 15,
2007. Early adoption is permitted. The Company is currently assessing the impact
of SFAS 159 which it will be required to adopt.

     In September 2006, the Securities and Exchange Commission issued SAB 108,
which provided guidance on the consideration of the effects of prior year
misstatements in quantifying current year misstatements for the purpose of a
materiality assessment. SAB 108 was effective for fiscal years ending after
November 15, 2006. The adoption of SAB 108 did not have a material impact on the
Company's financial position or results of operations.

4.  STOCK-BASED COMPENSATION

     STOCK INCENTIVE PLANS - The Company has granted options to purchase the
Company's common stock to employees and directors under various stock incentive
plans. Under the plans, employees and non-employee directors are eligible to
receive awards of various forms of equity-based incentive compensation,
including stock options, restricted stock, and performance awards, among others.
The plans are administered by the Board of Directors or the Compensation
Committee of the Board of Directors, which determine the terms of the awards
granted. Stock options are generally granted with an exercise price equal to the
market value of a share of common stock on the date of grant, have a term of ten
years or less, and vest over terms of two to three years from the date of grant.

     STOCK OPTION PLANS - The Company has two stock option plans, the 1994
Equity Incentive Plan (1994 Plan) and the 2001 Incentive Plan (the 2001 Plan).

     Under the terms of the 1994 Plan, the Company may no longer award any
options. All options previously granted under the 1994 Plan may be exercised at
any time up to ten years from the date of award.

     Under the terms of the 2001 Plan, the Company may grant options to purchase
up to a maximum of 1,373,809 shares of common stock to certain employees,
directors and consultants. On May 18, 2006, at the Company's Annual Meeting of
Stockholders, the Company's stockholders approved an amendment to the Company's
2001 Incentive Plan to increase the number of shares of Common Stock authorized
for issuance under the Incentive Plan by 1,250,000 from 123,809, resulting in a
maximum of 1,373,809 shares of Common Stock that may be granted as options. The
options may be awarded as incentive stock options (employees only) and
non-incentive stock options (certain employees, directors and consultants).

     The 2001 Plan and the 1994 Plan state that the exercise price of options
shall not be less than fair market value at the date of grant. Under the terms
of the 1994 Plan, the Company may no longer award any options. All options
previously granted under the 1994 Plan may be exercised at any time up to ten
years from the date of the award. The 2001 Plan has a total of 1,373,809 shares
reserved for issuance, as of December 31, 2006, there were outstanding options
of 77,155 with 1,296,654 shares remaining available for future grants.

     STOCK-BASED COMPENSATION - Prior to January 1, 2006, the Company had
followed Accounting Principles Board ("APB") Opinion No. 25, "Accounting for
Stock Issued to Employees", and related interpretations, which resulted in the
accounting for grants of awards to employees at their intrinsic value in the
consolidated financial statements. Accordingly, no compensation expense was
recorded for options issued to employees in fixed amounts and with fixed
exercise prices equal to the fair market value of the Company's common stock at
the date of grant. Effective January 1, 2006, the Company adopted FAS No.
123(R), "Accounting for Stock-Based Compensation," ("FAS 123(R)") using the
modified prospective method, which results in the provisions of FAS 123(R) being
applied to the financial statements on a going-forward basis. FAS 123(R)
requires companies to recognize stock-based compensation awards granted to its
employees as compensation expense on a fair value method. Under the fair value
recognition provisions of FAS 123(R), stock-based compensation cost is measured
at the grant date based on the fair value of the award and is recognized as
expense over the service period, which generally represents the vesting period.
The grant date fair value of stock options is calculated using the Black-Scholes
option-pricing model and the grant date fair value of restricted stock is based
on intrinsic value. The expense recognized over the service period is required
to include an estimate of the awards that will be forfeited.

     All stock-based awards to non-employees are accounted for at their fair
market value in accordance with FAS 123(R) and Emerging Issues Task Force No.
96-18, "Accounting for Equity Instruments That Are Issued to Other Than
Employees for Acquiring, or in Conjunction with Selling, Goods or Services."
Under this method, the equity-based instrument was valued at either the fair
value of the consideration received or the equity instrument issued on the date
of grant. The resulting compensation cost was recognized and charged to
operations over the service period, which was usually the vesting period.

                                      F-12


     As a result of adopting FAS 123(R), the impact to the Statement of
Operations for 2006 was $941,127, or $0.07 per share, all of which was recorded
in marketing, general and administrative.

     For purposes of recording stock option-based compensation expense as
required by Statement No. 123(R), the fair values of each stock option granted
under the Company's stock option plan for the fiscal year ended December 31,
2006 were estimated as of the date of grant using the Black-Scholes
option-pricing model.

     The fair values of all stock option grants issued were determined using the
following assumptions:

                                                    YEAR ENDED DECEMBER 31, 2006
                                                    ----------------------------

      Risk-free interest rate                                4.86%
      Expected life of option grants                        6 years
      Expected volatility of underlying stock                 102%
      Expected dividend payment rate, as a percentage
        of the stock price on the date of grant                0%

     The dividend yield assumption is based on the Company's history and
expectation of future dividend payouts. The Company estimated stock price
volatility using the historical volatility in the market price of its common
stock for the expected term of the options. The risk-free interest rate
assumption is based upon the U.S. Treasury yield curve in effect at the time of
grant for periods corresponding with the expected life of the option.

     As share-based compensation expense is recognized based on awards
ultimately expected to vest, it must be reduced for estimated forfeitures. FAS
123(R) requires forfeitures to be estimated at the time of grant and revised, if
necessary, in subsequent periods if actual forfeitures differ from those
estimates. Forfeiture rates are calculated based on actual historical
forfeitures.

     The expected life of employee stock options represents the weighted-average
period the stock options are estimated to remain outstanding. The expected life
of employee stock options is, in part, a function of the options' remaining
contractual life and the extent to which the option is in-the-money (i.e., the
average stock price during the period is above the strike price of the stock
option). The Company estimates that, based on these variables, options are
likely on average to be exercised in approximately 6 years.

     SFAS No. 123 requires the presentation of pro forma information for the
comparative periods prior to the adoption as if all of the Company's employee
stock options had been accounted for under the fair value method of the original

     For purposes of determining the disclosures required by SFAS No. 123, the
fair values of each stock option granted in the fiscal years ended December 31,
2005 and 2004 under the Company's stock option plan were estimated on the date
of grant using the Black-Scholes option-pricing model. The Company granted 9,142
and 31,319 options under its Stock Option Plans for the years ended December 31,
2005 and 2004, respectively.

     The Company uses the Black-Scholes option-pricing model to estimate the
fair value of the options at the grant date. The weighted average grant date
fair value of all stock option grants issued for the years ended December 31,
2005 and 2004 was $91,907 and $178,852, respectively, using the following
assumptions:

     STOCK OPTION ACTIVITY - During the year ended December 31, 2006, the
Company granted stock options to existing employees and Directors, as part of
the Company's yearly review process. All such options were granted with exercise
prices equal to the current market value of the underlying common stock on the
date of grant. Stock option activity under the 1994, and 2001 Plans was as
follows:

     As of December 31, 2006, there was $535,008 of total expected unrecognized
compensation cost related to unvested stock options granted under the Company's
stock-based compensation plans. That cost is expected to be recognized over a
period of three years.

     STOCK AND STOCK OPTION ISSUANCES TO NON-EMPLOYEES - During 2006 and 2005,
there were no options granted to non-employees or consultants. During 2004, the
Company issued stock grants and options to consultants and recorded unearned
compensation of $15,322.

     STOCK AND STOCK OPTION ISSUANCES OUTSIDE THE STOCK OPTION PLANS - During
2006, options to purchase an aggregate of 945,000 shares of common stock were
granted to executive officers and directors of the Company. One third of the
options vested on the date of grant and the remaining options vest over a two
year period with an exercise price of $1.62. On the date of the grant, the per
share fair value of these options was $1.32.

     During 2006, 75,000 shares of restricted stock were granted to Robert J.
DeLuccia, the Company's Chief Executive Officer. The restricted stock vests if
and when the Company's common stock trades at or above $4.00 per share for
thirty consecutive trading days. No compensation expense was recorded as vesting
was not considered probable.

     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.

5.   STOCKHOLDERS' EQUITY.

     AUTHORIZED CAPITAL STOCK - Authorized capital stock consists of 100,000,000
shares of $.01 par value common stock of which 2,620,679 shares are issued
(2,620,150 are outstanding) and 21,431,437 are reserved for issuance upon
exercise of common stock options and warrants and conversion of Series C
Cumulative Convertible Preferred Stock at December 31, 2006. 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 1,500 shares have been designated Series C Cumulative
Convertible Preferred Stock of which 805 shares were outstanding at December 31,
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 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. 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
2004, 2005 and 2006. At December 31, 2006, 529 repurchased shares remain
available for future use and 16,180 shares are available to be repurchased.

     SERIES C CONVERTIBLE PREFERRED STOCK - On December 23, 2005, pursuant to
the terms of a Preferred Stock and Warrant Purchase Agreement (the "Purchase
Agreement"), the Company completed the first closing of a private placement (the

                                      F-15

"Series C Financing") in which institutional investors (the "Purchasers")
acquired 250 shares of Series C Cumulative Convertible Preferred Stock (the
"Series C Preferred Stock") and six-year warrants (the "Warrants") to purchase
2,380,951 shares of common stock at an exercise price of $1.26 per share, for an
aggregate purchase price of $2.5 million (the "First Closing"). The net proceeds
from the First Closing were $2,125,943. In the second closing of the Series C
Financing, on February 13, 2006, the Company issued to institutional investors
575.5 shares of 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 approximately $5.75 million (the
"Second Closing"). The net proceeds from the Second Closing were $5,186,908. The
terms of the Series C Preferred Stock and Warrants issued in the First Closing
and the Second Closing were identical.

     RELEVANT MATERIAL TERMS: The terms and provisions of the Series C Preferred
Stock are set forth in the Certificate of Designations, Rights and Preferences
of Series C Cumulative Convertible Preferred Stock (the "Certificate of
Designations"). Certain material terms of the Series C Preferred Stock relevant
to this response are summarized below:

     OBLIGATIONS TO REGISTER SHARES: When issued, the securities offered and
sold to the Purchasers in the Series C Financing were not registered under the
Securities Act of 1933, as amended (the "Securities Act") and were sold in
reliance upon the exemption from securities registration afforded by Regulation
D under the Securities Act. All of the Purchasers represented to MacroChem that
they were "accredited investors", as defined in Rule 501 of Regulation D. In
connection with the Series C Financing, MacroChem entered into an Investor
Rights Agreement with the Purchasers, pursuant to which MacroChem was required
to file a registration statement with the Securities and Exchange Commission
covering the resale of the common stock issuable upon conversion of the Series C
Preferred Stock, issuable as payment of dividends on the Series C Preferred
Stock and issuable upon exercise of the Warrants and the warrants issued to the
placement agent, no later than March 27, 2006, and to use its best efforts to
cause the registration statement to become effective within a specified time
period. The registration statement became effective on April 18, 2006.

     DIVIDENDS: The Series C Preferred Stock accrues dividends at the rate of
10% of the stated price annually, payable quarterly in cash or common stock. The
first dividend payment date was March 31, 2006.

     LIQUIDATION: Upon liquidation, dissolution or winding up, the holders of
Series C Preferred Stock are entitled, before any distributions are made to the
holders of the common stock, or any other class or series of capital stock of
the Company ranking junior to the Series C Preferred Stock as to such
distributions, to be paid an amount equal to $10,000 per share and any unpaid
dividends thereon, subject to adjustment.

     VOTING: The Certificate of Designations contains a provision that restricts
a holder of Series C Preferred Stock from (i) converting Series C Preferred
Stock into common stock to the extent that such conversion would result in the
holder owning more than 4.95% of the issued and outstanding common stock of the
Company or (ii) voting together with the common stock on an as-if-converted to
common stock basis in respect of more than 4.95% of the issued and outstanding
common stock of the Company. The Warrants issued pursuant to the purchase
agreement contain a similar restriction (collectively, the "Beneficial Ownership
Cap"). A holder of Series C Preferred Stock or a Warrant may elect, subject to
certain conditions, to be exempt from the Beneficial Ownership Cap. Subject to
the Beneficial Ownership Cap restrictions, as of the date of the second closing
of the private placement financing in February 2006 (the "Second Closing"), the
Series C Preferred Stock acquired by the purchasers was convertible into
4,057,885 shares of common stock and the holders of the Series C Preferred Stock
vote on an as-converted basis with the holders of our common stock, and
therefore held approximately 80.28% of the voting power of our outstanding
securities. Assuming both the conversion of the Series C Preferred Stock and the
exercise of all of the Warrants acquired by the purchasers, in each case subject
to the Beneficial Ownership Cap restrictions, the purchasers would have held
approximately 89.06% of the outstanding common stock of the Company as of the
date of the Second Closing.

     REDEMPTION: If the Company fails or refuses to convert any shares of Series
C Preferred Stock in accordance with the terms of the Series C Preferred Stock,
the holders of the Series C Preferred Stock are entitled to elect to require the
Company to redeem their Series C Preferred Stock. In the event of a redemption,
the redemption price per share of Series C Preferred Stock is an amount in cash
equal to the greater of (1) all accrued but unpaid dividends as of the date the
holder makes the demand for redemption with respect to each share to be redeemed
plus the $10,000 liquidation preference per share or (2) the total number of


                                      F-16


shares of common stock into which such Series C Preferred Stock is convertible
multiplied by the then-current market price of the common stock.

     Given that the redemption provision described above does not embody an
unconditional obligation requiring the Company to redeem the instrument at a
specified or determinable date or upon an event certain to occur, the Series C
Preferred Stock is not a mandatorily redeemable financial instrument. Therefore,
the Company determined that the guidance in FAS 150, ACCOUNTING FOR CERTAIN
FINANCIAL INSTRUMENTS WITH CHARACTERISTICS OF BOTH LIABILITIES AND EQUITY, which
requires liability classification for mandatorily redeemable financial
instruments, does not apply.

     Rule 5-02.28 of Regulation S-X requires securities with redemption features
that are not solely within the control of the issuer to be classified outside of
permanent equity. The holders of the Series C Preferred Stock control a majority
of the voting power of the Company's common stock and, as a result of this
control, could directly or indirectly influence the triggering of the redemption
provision by, for example, refusing to approve an increase in the authorized but
unissued shares of common stock of the Company if, in the future, such increase
were necessary to effect the conversion of the Series C Preferred Stock.
Accordingly, the redemption provision is not solely within the Company's
control, and thus the Series C Preferred Stock is not permanent equity.

     Because the Series C Preferred Stock did not qualify for treatment as a
liability or as permanent equity as described above, the Company recorded the
portion of the proceeds attributable to the Series C Preferred Stock as
mezzanine equity pursuant to EITF Topic D-98, Classification and Measurement of
Redeemable Securities. Because the Company has a substantial amount of
authorized but unissued common stock (in excess of 95 million shares), the
occurrence of a redemption event is not considered probable, and thus the
carrying value of the Series C Preferred Stock is not being accreted to its
redemption value.

     CONVERSION: Each convertible preferred share is convertible into shares of
common 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 but unpaid dividends thereon by
$1.05. The conversion price for the Series C Preferred Stock and the Warrant
exercise price were each subject to reset adjustment such that if the average
price of the common stock over the twenty trading days immediately preceding May
8, 2006 (the "Average Price") was lower than the conversion and/or exercise
price, then such conversion and/or exercise price would have been adjusted to
equal the Average Price.

     The Company evaluated whether the embedded conversion feature in the Series
C Preferred Stock required bifurcation and determined, in accordance with
paragraph 12 of SFAS 133, that the economic characteristics and risks of the
embedded conversion feature in the Series C Preferred Stock were clearly and
closely related to the underlying common stock. In conducting this evaluation,
the Company recognized that the cumulative fixed dividend and the potential
redemption requirement of the Series C Preferred Stock are characteristics of
debt. The Company also recognized, however, that the Series C Preferred Stock
had the following equity-like characteristics: the Series C Preferred Stock
clearly gives the stockholders both existing and ongoing rights of ownership
(i.e., a residual interest), as the holders of Series C Preferred Stock are
entitled to vote on an as-converted basis with the holders of our common stock;
the dividend, while fixed, is payable quarterly in cash or common stock at the
Company's election, and, to date, the Company's Board of Directors has declared
each quarterly dividend to be paid in shares of common stock; the redemption
rights of the Series C preferred stock are perpetual and do not have a stated
maturity or redemption date, unlike debt instruments; and the right of the
holders of the Series C Preferred stock to receive payments, including the
liquidation preference, is not secured by any collateral. Consequently, when all
of the economic characteristics and risks of the Series C Preferred Stock are
considered as a whole, the Company concluded that the Series C Preferred Stock
is more akin to equity than to debt and, as a result, the Company concluded that
bifurcation was not required under SFAS 133.

     Pursuant to the guidance in paragraph 5 of EITF 00-27, APPLICATION OF ISSUE
NO. 98-5 TO CERTAIN CONVERTIBLE INSTRUMENTS, the Company allocated the proceeds
from the Series C financing between the Series C Preferred Stock and the
warrants based upon their estimated fair values as of the closing date. The
Company then calculated the intrinsic value of the beneficial conversion feature
embedded in the Series C Preferred Stock. As the amount of the beneficial
conversion feature exceeded the value allocated to the Series C Preferred Stock,
the amount of the beneficial conversion feature recorded was limited to the
proceeds allocated to the Series C Preferred Stock. The beneficial conversion
value was recognized as an additional discount on the Series C Preferred Stock
                                      F-17

which amount was immediately accreted and treated as a deemed dividend to the
holder of the shares of Series C Preferred Stock as all of the Series C
Preferred Stock was eligible for conversion upon issuance.

     STOCK SALES - In March 2004, the Company sold 128,619 shares of common
stock and warrants to purchase 25,723 shares of common stock to primarily
institutional investors. Gross proceeds were $7,292,700 ($6,681,274 net of
issuance costs) and were allocated between the common stock and the warrants
based on the relative fair value of the warrants and common stock. In April
2005, the Company sold approximately 65,040 shares of common stock and warrants
to purchase 32,520 shares of common stock to institutional investors and to
certain executive officers and directors of the Company. Gross proceeds were
$815,000 ($601,342 net of cash issuance costs) and were allocated between the
common stock and the warrants based on the relative fair value of the warrants
and common stock.

     WARRANTS - In addition to the issuance of shares of Series C Preferred
Stock, the Company issued warrants to the investors to purchase an aggregate of
up to 2,380,951 and 5,480,952 shares of common stock at a per share exercise
price of $1.26 per share in 2005 and 2006, respectively. In addition, the
Company issued warrants to the placement agent to purchase 238,095 and 548,095
shares of Common Stock at a per share exercise price of $1.05 per share, in 2005
and 2006, respectively. The warrants have a term of exercise expiring in 6
years. The warrants contain a "cashless exercise" feature that allows the
holders, under certain circumstances, to exercise the warrants without making a
cash payment to the Company. In addition, upon the occurrence of a change of
control, a warrant holder, at its option, can require the Company to repurchase
the warrant for an aggregate purchase price, payable in cash, calculated
according to a specified formula (the "Put Feature").

     The Company allocated the proceeds between the stock and the warrants based
upon their estimated fair values as of the closing date. The Company determined
the fair value of the warrants using the Black-Scholes option pricing model with
the following assumptions: weighted average risk free rate of 4.18%; volatility
of 100% and a dividend yield of 0%. The Company determined that the warrants
meet the definition of a derivative instrument as defined in SFAS 133,
Accounting for Derivative Instruments and Hedging Activities. The fair value of
the warrants are recorded as liabilities pursuant to the guidance in paragraphs
12 and 27 of EITF 00-19, ACCOUNTING FOR DERIVATIVE FINANCIAL INSTRUMENTS INDEXED
TO, AND POTENTIALLY SETTLED IN, A COMPANY'S OWN STOCK, because the Put Feature
is a form of net cash settlement in that it allows a holder of the warrant to
require the Company to repurchase the warrant for cash in the event of a change
in control. Changes in the fair value of the warrants are recorded each
reporting period through earnings.

     On April 19, 2005, the Company closed a private placement in which
institutional investors and certain executive officers and directors of the
Company received warrants to purchase approximately 32,520 shares of common
stock for a period of five years. The exercise price of the warrants is $14.70
per share for the institutional investors and $21.84 for the participating
executive officers and directors. As of December 31, 2005, approximately 6,012
of the $14.70 warrants issued to the institutional investors had been exercised
and none of the $21.84 warrants issued to participating executive officers and
directors had been exercised. The placement agent in this transaction received a
warrant to purchase approximately 1,190 shares of common stock at a purchase
price of $14.70 for a period of five years. As of December 31, 2005, none of the
$14.70 warrants issued to the placement agent had been exercised.

     During 2004, the Company conducted a private placement in which primarily
institutional investors received warrants to purchase an aggregate of 25,723
shares of common stock at a purchase price of $87.78 per share for a period of
five years. As of December 31, 2005, none of the $87.78 warrants had been
exercised.

     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,
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.

                                      F-18


     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.

6.  COMMITMENTS AND CONTINGENCIES.

     At December 31, 2006, the Company had no long-term contractual obligations.

7.  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, 2006, the Company has available net operating loss carryforwards of
approximately $73,367,079 for federal income tax purposes, expiring through 2026
and $42,199,117 for state income tax purposes, expiring through 2011. In
addition, the Company has unused investment and research and development tax
credits for federal and state income tax purposes aggregating $1,615,177 and
$859,871, 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, 2006 and 2005 are as follows:




                                                                   2006                    2005

                                      F-19


     For the year ended December 31, 2006 the valuation allowance decreased by
approximately $423,000 and for the year ended December 31, 2005 increased by
approximately $1,345,000, respectively, due to the uncertainty of future
realization of currently generated net operating loss and tax credit
carryforwards.

8.  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 did not make any matching contributions for the year
ended December 31, 2006. The Company contributed 953 shares of common stock in
2005 and 1,288 shares of common stock in 2004, valued at $15,610 and $59,060,
respectively. The Company also contributed $42,539 in cash to the Plan in 2005.

     The quarters ended March 31, June 30 and September 30, 2006 have been
restated (Notes 1 and 5). The restatement is in connection with the Series C
Cumulative Convertible Preferred Stock Offering, the Company issued warrants to
the private placement agent for services rendered. The fair value of the award
was originally accounted for as an offset to the proceeds of the Series C
Preferred offering and a credit to additional paid in capital. Upon further
review of the terms of the warrants, it was determined that the private
placement agent's warrants' put feature enables the holder, at their option, to
require the Company to repurchase the award for cash in the event of a change in
control. The Company determined that the warrants meet the definition of a
derivative investment as defined in SFAS 133, Accounting for Derivative
Financial Instruments Indexed to, and Potentially Settled in, a Company's Own
Stock, and should be adjusted to its current fair value at each reporting period
and classified as a warrant liability. As such, the net loss for the quarter
ended March 31, 2006 increased by $250,496, and the net income for the quarters
ended June 30, 2006 and September 30, 2006, increased by $260,764 and $438,854,
respectively.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law ("DGCL") provides that
a corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal or investigative (other than an action by or
in the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor, against expenses actually and
reasonably incurred in connection with the defense or settlement of such action
or suit if he acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

     Section 102(b)(7) of the DGCL permits a corporation to include in its
certificate of incorporation a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL (relating to
unlawful payment of dividends and unlawful stock purchase and redemption) or
(iv) for any transaction from which the director derived an improper personal
benefit.

     Our Certificate of Incorporation provides that our directors shall not be
liable to us or our stockholders for monetary damages for breach of fiduciary
duty as a director except to the extent that exculpation from liabilities is not
permitted under the DGCL as in effect at the time such liability is determined.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     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, all share amounts and
per share data in this Item 15 reflect the effect of these reverse splits.

     During the three years preceding the filing of this registration statement,
we issued the following securities which were not registered under the
Securities Act of 1933, as amended:

     o    On September 10, 2003, we sold 108,420 shares of our common stock for
          approximately $3,246,000 in gross proceeds ($2,971,505 net of issuance
          costs) in a private placement to primarily institutional investors.
          The investors in the September 2003 common stock transaction received
          warrants to purchase an aggregate of 21,684 shares of common stock at
          a purchase price of $49.266 per share for a period of three years. As
          of March 7, 2006, 9,011 of these investor warrants had been exercised.
          J.P. Carey Securities, Inc. served as the placement agent for the
          transaction and received a warrant to purchase 3,571 shares of common
          stock at a purchase price of $49.266 for a period of three years. As
          of March 7, 2006, none of these placement agent warrants had been
          exercised.

     o    On March 9, 2004, we sold 128,619 shares of our common stock for
          $7,292,700 in gross proceeds ($6,681,274 net of issuance costs) in a
          private placement to institutional investors. The investors also
          received warrants to purchase an aggregate of 25,723 shares of common
          stock at a purchase price of $87.78 per share expiring five years from
          the closing date. As of As of March 7, 2006, none of these warrants
          had been exercised. JMP Securities LLC acted as placement agent in
          connection with this transaction and was paid a fee of $510,489 for
          their services.

     o    On April 19, 2005, we sold 65,035 shares of common stock and five-year
          warrants to purchase 32,516 shares of our common stock for
          approximately $815,000 in gross proceeds ($601,342 net of cash
          issuance costs). The securities were sold in units, with each unit
          containing one share of common stock and a warrant to purchase
          one-half of a share of common stock. Institutional investors purchased
          47,615 units at a purchase price per unit of $10.50, with the
          accompanying warrants of 23,807 shares having an exercise price of
          $14.70 per share. As of March 7, 2006, approximately 6,012 of these
          investor warrants had been exercised. Certain of the Company's
          executive officers and directors purchased 17,420 units at a per unit
          purchase price of $18.081, with the accompanying warrants of 8,709
          shares having an exercise price of $21.84 per share. As of March 7,
          2006, none of these management warrants had been exercised. The
          Placement Agent for the transaction received a five-year warrant to
          purchase approximately 1,190 shares of the Company's common stock at
          an exercise price of $14.70 per share. As of March 7, 2006, none of
          these placement agent warrants had been exercised.

     o    On December 23, 2005 and February 13, 2006, we sold an aggregate of
          825.5 shares of Series C Cumulative Convertible Preferred Stock and
          warrants to purchase 7,861,912 shares of our common stock for
          approximately $8,255,000 in gross proceeds ($7,391,043 net of issuance
          costs and, with respect to the February 13, 2006 closing, before legal
          and accounting fees) in a private placement to institutional
          investors. The warrants have an exercise price of $1.26 per share of
          common stock and have a term of six years. The Series C Cumulative
          Convertible 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. The conversion of the Series C Cumulative
          Convertible Preferred Stock and the exercise of the warrants are
          restricted in specified circumstances. As of March 7, 2006, none of
          the shares of Series C Cumulative Convertible Preferred Stock had been
          converted and none of the warrants had been converted. Six-year
          placement agent warrants to purchase 786,189 shares of our common


                                      II-2


          stock at an exercise price of $1.05 per share were issued in
          connection with SCO Securities LLC's services as placement agent in
          connection with the private placement. SCO Securities LLC allocated
          the placement agent warrants to the following four persons in the
          amounts listed: (i) warrant to purchase 471,713 shares of common stock
          to SCO Capital Partners LLC; (ii) warrant to purchase 157,238 shares

          78,619 shares of common stock to Mark Alvino and (iv) warrant to
          purchase 78,619 shares of common stock to Howard Fischer. As of March
          7, 2006, none of these placement agent warrants had been exercised.

     The sales and issuances listed above were deemed exempt from registration
under the Securities Act of 1933, as amended, by virtue of Rule 506 thereunder.

ITEM 17.    UNDERTAKINGS.

     The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

           (i) to include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

           (ii) to reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement.

           (iii) to include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement.

     (2) That, for purposes of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) That, for purposes of determining liability under the Securities Act of
1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of
a registration statement relating to an offering, other than registration
statements relying on Rule 430B or other than prospectuses filed in reliance on
Rule 430A, shall be deemed to be part of and included in the registration
statement as of the date it is first used after effectiveness. PROVIDED,
HOWEVER, that no statement made in a registration or prospectus that is part of
the registration statement or made in a document incorporated or deemed
incorporated by reference into the registration statement or prospectus that is
part of the registration statement will, as to a purchaser with a time of
contract of sale prior to such first use, supersede or modify any statement that
was made in the registration statement or prospectus that was part of the
registration statement or made in any such document immediately prior to such
date of first use.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under "Item 14--Indemnification
of Directors and Officers" above, or otherwise, the Registrant has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.


                                      II-7



                                   SIGNATURES

undersigned, thereunto duly authorized, in the Town of Wellesley, State of
