SUPPLEMENTAL DISCLOSURES OF CASH FLOW INFORMATION:

The Company did not pay any cash for interest expense or income taxes during the
six-month periods ended June 30, 2006 and 2005.

In February of 2006, the Company issued warrants for the purchase of
approximately 548,095 shares of its Common Stock to the designees of the
placement agent in connection with the sale of Series C Cumulative Convertible
Preferred Stock. The warrants were valued using the Black Scholes model at
$330,415 and are recorded as a non-cash issuance cost.

                NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

     All references to share amounts, share prices and per share data in the
Unaudited Condensed Financial Statements and these accompanying Notes 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)  BASIS OF PRESENTATION AND OPERATIONS The financial statements included
     herein have been prepared by MacroChem Corporation ("MacroChem" or the
     "Company") without audit, pursuant to the rules and regulations of the
     Securities and Exchange Commission. Certain information and footnote
     disclosures normally included in financial statements prepared in
     accordance with accounting principles generally accepted in the United
     States of America have been condensed or omitted pursuant to such rules and
     regulations. In the opinion of management, the accompanying unaudited
     condensed financial statements include all adjustments (consisting only of
     normal recurring adjustments) necessary to present fairly the financial
     position, results of operations and cash flows of the Company at the dates
     and for the periods indicated. The unaudited condensed financial statements
     included herein should be read in conjunction with the audited financial
     statements and the notes thereto included in the Company's Annual Report on
     Form 10-K for the fiscal year ended December 31, 2005.

     The Company has been engaged primarily in research and development since
     its inception in 1981 and has derived limited revenues from the commercial
     sale of its products, licensing of certain technology and feasibility
     studies. The Company has had no revenues relating to the sale of any
     products currently under development. The Company has incurred net losses
     every year since its inception and the Company anticipates that losses will
     continue for the foreseeable future. At June 30, 2006, the Company's
     accumulated deficit was $80,771,761. At June 30, 2006, the Company believes
     that its existing cash and cash equivalents are sufficient to fund
     operations under the Company's operating plan for at least the next twelve
     months. 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'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 results disclosed in the Statement of Operations for the six months
     ended June 30, 2006 are not necessarily indicative of the results to be
     expected for the full year.

(2)  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.

     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 in net loss 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 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.

     On March 29, 2005, the Securities and Exchange Commission ("SEC") published
     Staff Accounting Bulletin ("SAB") No. 107, which provides the Staff's views
     on a variety of matters relating to stock-based payments. SAB No. 107


                                       8
<PAGE>

     requires that stock-based compensation be classified in the same expense
     line items as cash compensation. The Company has classified stock-based
     compensation during the six months ended June 30, 2006 within the same
     operating expense line items as cash compensation paid to employees.

     Stock-based compensation expense under SFAS No. 123(R) was $216,640 and
     $674,597 during the three and six months ended June 30, 2006, respectively.
     As a result of adopting SFAS No. 123(R) on January 1, 2006, the Company's
     income from operations and income for the three and six months ended June
     30, 2006 were $216,640 and $674,597, respectively, lower than if it had
     continued to account for share-based compensation using the intrinsic
     method of accounting. Basic income per share would have been $3.59 and
     $2.37 if the Company had not adopted SFAS No. 123(R), compared to the
     reported basic income per share of $3.39 and $1.73 for the three and six
     months ended June 30, 2006, respectively. Diluted income per share
     would have been $3.59 and $.37 if the Company had not adopted SFAS No.
     123(R), compared to the reported diluted income per share of $3.39 and $.28
     for the three and six months ended June 30, 2006, respectively. The
     incremental impact of SFAS No. 123(R) during the three and six months ended
     June 30, 2006 represents stock-based compensation expense related to stock
     options.

     VALUATION ASSUMPTIONS FOR STOCK OPTIONS

     The fair value of stock options granted during the three and six months
     ended June 30, 2006 and 2005 was estimated using the Black-Scholes
     option-pricing model with the following assumptions:

<TABLE>

                                                                THREE AND SIX MONTHS ENDED
                                                                         JUNE 30,
                                                                  2006              2005
         <S>                                                    <C>               <C>

         Risk-free interest rate                                  4.72%             4.25%
         Expected life of option grants                          6 years           6 years
         Expected volatility of underlying stock                  102%               93%
         Expected dividend payment rate, as a percentage of
             the stock price on the date of grant                 ---                ---
</TABLE>

     The dividend yield assumption is based on the Company's history and
     expectation of future dividend payouts. The expected volatility is based on
     a combination of the Company's historical stock price and implied
     volatility. 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. The expected life of
     employee stock options represents the weighted-average period the stock
     options are expected to remain outstanding.

     PRO FORMA INFORMATION FOR PERIOD PRIOR TO SFAS 123(R) ADOPTION

     In accordance with FAS 123(R), the Company adopted the provisions of FAS
     123(R) at January 1, 2006 using the modified prospective approach. Under
     this method, prior periods are not restated. Had the Company previously
     recognized compensation costs as prescribed by FAS 123, previously reported
     net loss, basic earnings per share and diluted earnings per share would
     have changed to the pro forma amounts shown as follows:

     Potential common shares are not included in the per share calculations
     for diluted loss per share, because the effect of their inclusion would
     be anti-dilutive. Anti-dilutive potential shares not included in per
     share calculations for the three and six months ended June 30, 2005
     were 205,107 and 170,699, respectively. Dilutive shares not included in
     the income per share calculation for the three month period ended June
     30, 2006 were 17,603,385. These shares were not included as the closing
     average price of the Company's common shares for the three months ended
     June 30, 2006 was below the conversion and exercise price of the
     preferred stock, warrants and options.

5    STOCKHOLDERS' EQUITY

     AUTHORIZED CAPITAL STOCK - Authorized capital stock consists of 100,000,000
     shares of $.01 par value common stock of which 1,358,242 shares are issued
                                       11
<PAGE>

     (1,357,713 are outstanding) and 17,603,385 are reserved for issuance upon
     exercise of common stock options and warrants and conversion of Series C
     Cumulative Convertible Preferred Stock at June 30, 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 (823.95 shares were outstanding at
     June 30, 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 2003, 2004 and 2005. At June 30, 2006, 529

     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. In December 2005, the Company sold 250
     shares of Series C Cumulative Convertible Preferred Stock and warrants to
     purchase 2,380,951 shares of common stock to institutional investors. Gross

     The warrants are callable by the Company if the closing price of the stock
     is higher than $755.58 for 15 consecutive trading days at any time before
     expiration. As a result of subsequent financing transactions, the exercise
     price of these warrants has been adjusted to $277.62 in accordance with the

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

NOTE REGARDING FORWARD LOOKING STATEMENTS

     This report and the documents incorporated in this report by reference may
contain "forward-looking statements" within the meaning of Section 21E of the
Securities Exchange Act of 1934, as amended (the "EXCHANGE Act"). These
statements may be identified by the use of forward-looking words or phrases such
as "anticipate," "believe," "could," "expect," "intend," "look forward," "may,"
"planned," "potential," "should," "will," and "would." These forward-looking
statements reflect our current expectations and are based upon currently
available data. The Private Securities Litigation Reform Act of 1995 provides a
"safe harbor" for such forward-looking statements. In order to comply with the
terms of the safe harbor, we note that a variety of factors could cause actual
results and experience to differ materially from the anticipated results or
other expectations expressed in the forward-looking statements. These factors
include, but are not limited to: our history of operating losses, our decision
to discontinue research and development activities and our need for additional
external financing; our need for significant additional product development
efforts and additional financing; technological uncertainty relating to
transdermal drug delivery systems; the early stage of development of our
proposed products; the lack of success of our prior development efforts;
uncertainties related to clinical trials of our proposed products; uncertainties
relating to government regulation and regulatory approvals; our dependence on
third parties for the FDA application process; uncertainties regarding market
acceptance of our product candidates; uncertainties regarding the potential
health risks of hormone replacement therapies; our ability to identify and
obtain rights to products or technologies in order to build our portfolio of
product candidates; our ability to recruit additional key employees; our limited
personnel and our dependence on continued access to scientific talent; no
assurance of our entering into license arrangements; our lack of laboratory
facilities and scientific personnel and uncertainties regarding our reliance on
third parties to conduct research and development activities for our
technologies and product candidates; uncertainties relating to competition,
patents and proprietary technology; our dependence on third parties to conduct
research and development activities; our dependence on third-party suppliers and
manufacturers; uncertainties relating to risks of product liability claims, lack
of product liability insurance, and expense and difficulty of obtaining adequate
insurance coverage; our majority shareholders, who own a large portion of our
voting stock, could control company decisions and could substantially lower the
market price of our common stock if they were to sell large blocks of our common
stock in the future; uncertainty of pharmaceutical pricing and related matters;
volatility of our stock price; the effect that our quotation on the OTC Bulletin
Board will have on the liquidity of our common stock; and dilution of our shares
as a result of our contractual obligation to issue shares in the future.
Additional information on these and other factors which could affect the
Company's actual results and experience are included in the Company's Annual
Report on Form 10-K for the year ended December 31, 2005 and, in particular, the
section entitled "Risk Factors".

     These or other events or circumstances could cause our actual performance
or financial results in future periods to differ materially from those expressed
in the forward-looking statements. We undertake no obligation to make any
revisions to the forward-looking statements contained in this report or the
documents incorporated by reference in this report, or to update the


                                       15
<PAGE>

forward-looking statements to reflect events or circumstances occurring after
the date of this report.

GENERAL

     On December 30, 2005 we implemented a 1-for-7 reverse stock split of our
common stock and on February 9, 2006 we implemented a subsequent 1-for-6 reverse
stock split of our common stock. Unless otherwise noted, data used throughout
this Quarterly Report on Form 10-Q has been adjusted to reflect these reverse
splits.

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

     Since inception, we have been engaged primarily in research and
development. We have not generated any meaningful revenues from operations and
we have sustained significant operating losses. We anticipate that we will
continue to incur significant losses for the foreseeable future. We cannot
guarantee that we will be successful in commercializing our products, or that we
will ever become profitable. As of June 30, 2006, we had an accumulated deficit
of $80,771,761. 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.

     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; and

                                       16
<PAGE>

     o the signing of licenses and product development agreements.

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

     We expect to continue to spend significant amounts on developing and
seeking regulatory approval of our lead product, EcoNail. Ultimately, if we
receive regulatory approval for EcoNail, significant expenses may 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 believe that our existing cash and cash equivalents and short term
investments of $6,527,627 as of June 30, 2006 will be sufficient to meet our
operating expenses and capital expenditure requirements for at least the next
twelve months.

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

     o salaries and expenses for our research and development personnel;

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

     o costs associated with conducting our clinical trials;

     o costs of developing and obtaining regulatory approvals; and

     o allocable costs, including occupancy and depreciation.

     Because a 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 three-month period
ended June 30, 2006, we spent $90,243 on research and development, including
$83,215 in costs associated with a clinical trial for EcoNail and $7,028 in
costs not specifically tracked to a project. For the three months ended June 30,
2005, we spent $739,008 on research and development, including $22,965 and
$111,739 in costs associated with our clinical trials for EcoNail and Opterone,
respectively, and $604,304 in costs not specifically tracked to a project. For
the six-month period ended June 30, 2006, we spent $156,225 on research and
development, including $147,847 in costs associated with a clinical trial for
EcoNail and $8,378 in costs not specifically tracked to a project. For the six
months ended June 30, 2005, we spent $1,769,068 on research and development,
including $195,434 and $327,434 in costs associated with our clinical trials for
EcoNail and Opterone, respectively, and $1,246,200 in costs not specifically
tracked to a project.

     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. Moreover, we may elect not to develop Opterone further if we cannot
find a partner. In addition, these risks and uncertainties also prevent us from
estimating with any certainty the specific timing and future costs of our
clinical development programs, although historical trends at similarly situated
companies indicate that research and development expenses tend to increase in
later stages of clinical development. Our failure to obtain requisite
governmental approvals timely or at all will delay or preclude us from licensing
or marketing our products or limit the commercial use of our products, which
could adversely affect our business, financial condition and results of
operations.

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

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Our discussion and analysis of our financial condition and results of
operations are based on our financial statements, which have been prepared in
accordance with accounting principles generally accepted in the United States of
America. The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
revenues and expenses. Note 1 to our financial statements included within our
Annual Report on Form 10-K for the year ended December 31, 2005, 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.

     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


                                       18
<PAGE>

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.

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

RESULTS OF OPERATIONS

     We had no revenues for the three-month and six month periods ending June
30, 2006 and June 30, 2005. For the year ending December 31, 2006, we do not
expect to have any revenues.

     For the three-month period ended June 30, 2006, research and development
costs decreased by $648,765, or 87.8%, to $90,243 from $739,008 in the
three-month period ended June 30, 2005. The decrease is primarily attributable
to the temporary cessation of research and development activities in August
2005, including a reduction in spending on clinical trials of $51,489 in the
three-month period ended June 30, 2006 compared with the same period in 2005. In
addition, there was a reduction in payroll and related expenses of $246,409 and
a reduction in laboratory operating expenses of $334,528 in the three-month
period ended June 30, 2006. For the six-month period ended June 30, 2006,
research and development costs decreased by $1,612,843, or 91.2%, to $156,225
from $1,769,068 in the six-month period ended June 30, 2005. The decrease is
primarily attributable to the temporary cessation of research and development
activities in August 2005, including a reduction in spending on clinical trials
of $418,266 in the six-month period ended June 30, 2006 compared with the same
period in 2005. In addition, there was a reduction in payroll and related
expenses of $516,346 and a reduction in laboratory operating expenses of
$661,893 in the six-month period ended June 30, 2006 compared to the same period
in 2005. For each of the next two quarters, we expect research and development
spending to increase significantly from the level seen in the first two quarters
of 2006 as we expect to commence a clinical trial for EcoNail in the third
quarter of 2006.

     For the three-month period ended June 30, 2006, marketing, general and
administrative costs increased by $167,280, or 20.7%, to $976,560, from $809,280
in the three-month period ended June 30, 2005. The increase is 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 $216,640. The Company also
incurred additional costs of $30,000 relating to certain SEC and other filings.
In addition, expenses relating to conferences and investor relations meetings
increased by approximately $50,000. The effect of these amounts on marketing,
general and administrative expenses for the three-month period ended June 30,
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 $53,200
during the three-month period ended June 30, 2006. In addition, in the
three-month period ended June 30, 2006, legal and audit expenses decreased by
approximately $23,928 and patent and search fees decreased by approximately
$40,000. For the six-month period ended June 30, 2006, marketing, general and
administrative costs increased by $473,409, or 28.8%, to $2,117,687, from
$1,644,278 in the six-month period ended June 30, 2005. The increase is
primarily attributable to the Company's adoption of SFAS No. 123(R), which


                                       19
<PAGE>

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 $674,597. The Company
also incurred additional costs of $90,200 relating to certain SEC filings and
reverse stock splits. The effect of these amounts on marketing, general and
administrative expenses for the six-month period ended June 30, 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 $190,643 during
the six-month period ended June 30, 2006. In addition, in the six-month period
ended June 30, 2006, legal and audit expenses decreased by approximately
$36,900, insurance expenses decreased by approximately $12,000 and patent and
search fees decreased by approximately $40,000. For each of the next two
quarters, we expect marketing, general and administrative spending to
approximate the same level as seen in the second quarter of 2006.

     For the three-month period ended June 30, 2006, other income increased by
$4,944,033 to $4,965,975 compared to $21,942 in the three-month period ended
June 30, 2005. This 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. Application of EITF 00-19 resulted in a decrease
in the valuation of warrants of $4,892,565. Interest income for the three-month
period ended June 30, 2006 increased by $51,468 to $73,410 compared to interest
income of $21,942 in the three-month period ended June 30, 2005. The increase in
interest income is due to higher amounts of cash available for investing
purposes and higher interest rate returns available for cash that is invested.
For the six-month period ended June 30, 2006, other income increased by
$4,386,760 to $4,432,220 compared to $45,460 in the six-month period ended June
30, 2005. The increase is primarily the result of 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." Application of
EITF 00-19 resulted in a net decrease in the valuation of warrants of
$4,313,068. Interest income for the six-month period ended June 30, 2006
increased by $73,692 to $119,152 compared to interest income of $45,460 in the
three-month period ended June 30, 2005. The increase in interest income is due
to higher amounts of cash available for investing purposes and higher interest
rate returns available for cash that is invested.

     For the reasons described above, the Company's financial statements reflect
a net gain of $3,693,748 in the three-month period ended June 30, 2006 compared
with a net loss of $1,526,346 in the three-month period ended June 30, 2005. For
the six-month period ended June 30, 2006, the Company's financial statements
reflect a net gain of $1,801,337 compared with a net loss of $3,367,886 in the
six-month period ended June 30, 2005.

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 the first six months of 2006, we received no proceeds
from the exercise of options and warrants, and gross proceeds of $5,755,000
($5,186,908 net of cash issuance costs) as a result of the sale of our Series C
Cumulative Convertible Preferred Stock in a private placement financing


                                       20
<PAGE>

transaction. During the first six months of 2005, we received no proceeds from
the exercise of options and warrants or the sale of stock.

     At June 30, 2006, working capital was approximately $6.5 million, compared
to $2.8 million at June 30, 2005. The increase in our working capital reflects
the receipt of private placement proceeds, partially offset by the use of funds
in operations. 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 cash 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 $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 six-month period ended June 30, 2006,
we did not repurchase any shares of common stock. At June 30, 2006, 529
repurchased shares remain available for future use and 16,180 shares remain
available for repurchase under the plan.

     Capital and patent development expenditures were $36,169 for the first six
months of 2006. Capital and patent development expenditures were $50,121 for the
six-month period ended June 30, 2005. We anticipate additional capital and
patent expenditures will be approximately $50,000 for the remainder of the
fiscal year ending December 31, 2006.

     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 disclosed in our Annual Report on Form
10-K for the period ended December 31, 2005, we entered into employment
agreements of indefinite length with our three remaining executive officers on
February 13, 2006.

     As of June 30, 2006, we had $6,527,627 in cash, cash equivalents and
short-term investments. We believe that our existing cash and cash equivalents
will be sufficient to meet our operating expenses and capital expenditure
requirements for at least the next twelve months. Our cash requirements may vary
materially from those now planned because of changes in the focus and direction
of our research and development programs, competitive and technical advances,


                                       21
<PAGE>

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.

     As described in our current report on Form 8-K filed on July 25, 2006, we
entered into a 20-month sublease of approximately 4,000 square feet of office
space at, and relocated our principal executive offices to, 40 Washington St.,
Suites 220 and 240, Wellesley Hills, Massachusetts, 02481, effective as of June
1, 2006. Our new telephone number is (781) 489-7310. At June 30, 2006, with the
exception of this sublease, the Company had no long-term contractual
obligations.

RECENT ACCOUNTING PRONOUNCEMENTS

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

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

     As of June 30, 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 six months ending June 30, 2006.

                                       22
<PAGE>

ITEM 4.  CONTROL AND PROCEDURES

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

     There were no changes in our internal control over financial reporting that
occurred during the quarter ended June 30, 2006 that have materially affected,
or are reasonably likely to materially affect, our internal control over
financial reporting.

PART II - OTHER INFORMATION

ITEM 1A.  RISK FACTORS.

The following updates and supplements the risk factors included in Item 1A of
Part I of our Annual Report on Form 10-K for the year ended December 31, 2005.
Other than as set forth below, there have been no material changes to the risk
factors included in Item 1A of Part I of our Annual Report on Form 10-K for the
year ended December 31, 2005.

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

     We compete with a number of firms, many of which are large, multi-national
organizations with worldwide distribution. We believe that our major competitors
in the drug delivery sector of the health care industry include Bentley
Pharmaceuticals, Inc., Biosante Pharmaceuticals, Inc., NexMed, Inc., ALZA
Corporation, Connetics Corporation, Antares Pharma, Inc. and Barrier
Therapeutics, Inc. Competitors with approved products in the therapeutic areas
that our clinical stage product candidates seek to address include, with respect
to onychomycosis:

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

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

     o Sanofi Aventis (Dermik Laboratories), maker of Penlac(R), 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 other companies, including Nexmed, Inc., MediQuest
Therapeutics, Inc. and Anacor Pharmaceuticals, Inc., are also developing topical
and/or oral 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
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.

                                       24
<PAGE>

     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.
