              Notes to Unaudited Consolidated Financial Statements
                                 (June 30, 1997)



1.      Basis of Presentation

        The accompanying unaudited condensed consolidated financial statements
        have been prepared in accordance with generally accepted accounting
        principles for interim financial information and pursuant to the rules
        and regulations of the Securities and Exchange Commission. Accordingly,
        these financial statements do not include all of the information and
        footnotes required by generally accepted accounting principles for
        complete financial statements.

        The interim unaudited consolidated financial statements contained herein
        include, in management's opinion, all adjustments (consisting of normal
        recurring adjustments) necessary for a fair presentation of the
        financial position, results of operations, and cash flows for the
        periods presented. The results of operations for the interim period
        shown on this report are not necessarily indicative of results for a
        full year. These financial statements should be read in conjunction with
        the Company's consolidated financial statements and notes for the year
        ended December 31, 1996, appearing in the Company's Annual Report on
        Form 10-K for such year.


2.      Net Loss Per Share

        Net loss per share has been calculated by dividing net loss by the
        weighted average number of common shares outstanding during the period.
        All common stock equivalents have been excluded from the calculation of
        weighted average common shares outstanding since their inclusion would
        be anti-dilutive.


3.      Reverse Stock Split

        On June 6, 1997, the Company's stockholders approved a one-for-ten
        reverse split of the common stock effective as of June 9, 1997. All
        share and per share amounts have been retroactively restated to reflect
        the terms of the split.


4.      New Accounting Standard

        In February 1997, the Financial Accounting Standards Board issued
        Statement of Financial Accounting Standard No. 128, "Earnings per
        Share". The standard will be effective for both interim and annual
        periods, beginning with the Company's fiscal year ending December 31,
        1997. The adoption of this standard is not expected to have a material
        effect on the Company's financial statements.

5.      Investments

        At June 30, 1997, the cost basis of short-term investments exceeded
        their fair value by approximately $34,000. These investments, which are
        classified as available-for-sale, are reported at fair value, with the
        unrealized loss excluded from the statement of operations and reported
        as a separate component of stockholders' equity.


6.      Supplemental disclosure of non-cash investing and financing activities:

        During the six months ended June 30, 1997, the Company issued 1,394,020
        shares of common stock resulting from the conversion of 79,487 shares of
        preferred stock.

        During the six months ended June 30, 1996, $1 million of convertible
        subordinated debentures were converted into 156,605 shares of common
        stock.

Results of Operations

   Overview

      The Company is a biotechnology company engaged in the research and
development of novel therapeutic and diagnostic products to treat chronic
debilitating diseases such as cancer, central nervous system disorders and
autoimmune diseases. The Company expects that its research and development costs
will continue to increase as the Company attempts to gain regulatory approval
for commercial introduction of its proposed products. At June 30, 1997, the
Company is considered a "development stage enterprise" as defined in Statement
of Financial Accounting Standards No. 7.


   Three Months Ended June 30, 1997 and 1996

      The Company's net loss was $2,148,136 during the three months ended
June 30, 1997 as compared with $1,103,736 during the three months ended June 30,
1996. Net loss per common share equaled $.17 per share for the 1997 period as
compared to $.12 per share for the 1996 period. The higher net loss in the 1997
period was primarily due to increased research and development expenses, and
higher costs associated with the Phase III clinical trial for THERAFECTIN(R).
These increased expenses were partially offset by lower general and
administrative expenses.

      Revenue was $33,060 during the three months ended June 30, 1997 as
compared with $49,727 during the comparable 1996 period. Revenue for both
periods was attributable to a research and development agreement (the
"Agreement") entered into with Zeneca Pharmaceuticals, Ltd. ("Zeneca
Pharmaceuticals") in 1995. The Agreement expired in June 1997. The parties are
presently discussing an extension of the Agreement, the terms and conditions of
which are under negotiation.

      Research and development expenses were $1,355,762 during the three
months ended June 30, 1997 as compared with $528,913 during the three months
ended June 30, 1996. The increase was primarily attributable to an expansion in
the number of technologies under development as well as an increased level of
expenditures for technologies which were under development during both periods.
During the 1997 period, the Company incurred expenses totaling $276,000 for a
technology which had not yet been licensed to the Company during the comparable
1996 period. In addition, the Company increased the funding for two of its
programs from approximately $152,000 during the 1996 period to approximately
$573,000 during the 1997 period. Finally, the Company increased the number of


                                       6
<PAGE>
 
personnel supporting its research and development activities from two to four.
The majority of the Company's research and development expenses were sponsored
research obligations paid to Harvard University and its affiliated hospitals.
The Company expects to incur research and development costs between $5 million
and $6 million during 1997.

            Licensing fees were zero during the three months ended June 30, 1997
as compared with $50,000 during the three months ended June 30, 1996. The
Company did not execute any new licensing agreements during the 1997 period or
incur any obligations under its existing licensing agreements. The Company
entered into two new licensing agreements during the 1996 period. The Company
expects to pay future licensing fees, the timing and amounts of which will
depend upon the terms of agreements which may be executed for technologies
currently being developed or which may be developed in the future. There can be
no assurance regarding the likelihood or materiality of any such future
licensing agreements.

            THERAFECTIN(R) related expenses were $629,087 during the three
months ended June 30, 1997 as compared with $180,117 during the three months
ended June 30, 1996. This increase was primarily due to the higher number of
patients enrolled in the Phase III clinical trial for THERAFECTIN(R) during the
1997 period as compared to the 1996 period. Enrollment in the trial, which began
in March 1996, was completed in March 1997 and the trial is expected to be
completed in August 1997 with results available at the end of September 1997.
Before any commercially viable product from THERAFECTIN(R) may be developed, and
any revenue generated therefrom, the Company currently expects that at least
$500,000 to $1.0 million of additional future expense will be necessary. There
can be no assurance, however, that the expenditure of these additional amounts
will result in the regulatory approval of any compounds or that such approval
will ever be able to be obtained by the Company. Moreover, if the current Phase
III trial for THERAFECTIN(R) provides unsatisfactory or disappointing results,
the Company may be required to write off all or some portion of the $3.5 million
asset value represented by the THERAFECTIN(R) technology acquired in the Merger
with Greenwich Pharmaceuticals, Inc. as reflected on the Company's balance
sheet.

     General and administrative expenses were $479,580 during the three months
ended June 30, 1997 as compared with $630,899 during the comparable 1996 period.
This decrease was primarily due to lower professional services costs.

            Net interest income was $283,233 during the three months ended June
30, 1997 as compared with net interest income of $236,466 during the three
months ended June 30, 1996. The higher net interest income recognized during the
1997 period primarily related to a decrease in interest expense which totaled
approximately $1,000 during the 1997 period as compared to approximately $41,000
during the 1996 period. The higher net interest expense incurred during the 1996
period related to the issuance of $2.175 million of notes payable during the
first quarter of 1995 and the amortization of the debt issuance costs thereon.
The Company paid the remaining principal on the notes payable at the beginning
of the second quarter of 1996.


   Six Months Ended June 30, 1997 and 1996
            The Company's net loss was $3,813,024 during the six months ended
June 30, 1997 as compared with $2,649,333 during the six months ended June 30,
1996. Net loss per common share equaled $.32 per share for the 1997 period as
compared to $.30 per share for the 1996 period. The higher net loss in the 1997
period was primarily due to increased research and development expenses, and
higher costs associated with the Phase III clinical trial for THERAFECTIN(R).
These increased expenses were partially offset by lower general and
administrative expenses, and a greater amount of net interest income in the 1997
period as compared to the 1996 period.

            Revenue was $83,060 during the six months ended June 30, 1997 as
compared with $99,454 during the comparable 1996 period. Revenue for both
periods was attributable to the Agreement entered into with Zeneca in 1995. The
Agreement expired in June 1997. The parties are presently discussing an
extension of the Agreement, the terms and conditions of which are under
negotiation.

            Research and development expenses were $2,329,754 during the six
months ended June 30, 1997 as compared with $844,286 during the six months ended
June 30, 1996. The increase was primarily attributable to an expansion in the
number of technologies under development as well as an increased level of
expenditures for technologies which were under development during both periods.
During the 1997 period, the Company incurred expenses totaling approximately
$485,000 for a technology which had not yet been licensed to the Company during
the comparable 1996 period. In addition, the Company increased the funding for
two of its programs from approximately $247,000 during the 1996 period to
approximately $1,042,000 during the 1997 period. Finally, the Company increased
the number of personnel supporting its research and development activities from
two to four. The majority of the Company's research and development expenses
were sponsored research obligations paid to Harvard University and its
affiliated hospitals. The Company expects to incur research and development
costs between $5 million and $6 million during 1997.

            Licensing fees were zero during the six months ended June 30, 1997
as compared with $60,000 during the six months ended June 30, 1996. The Company
did not execute any new licensing agreements during the 1997 period or incur any
obligations under its existing licensing agreements. The Company entered into
two new licensing agreements during the 1996 period and made a contractual
payment under an existing licensing agreement. The Company expects to pay future
licensing fees, the timing and amounts of which will depend upon the terms of
agreements which may be executed for technologies currently being developed or
which may be developed in the future. There can be no assurance regarding the
likelihood or materiality of any such future licensing agreements.

            THERAFECTIN(R) related expenses were $1,180,132 during the six
months ended June 30, 1997 as compared with $547,379 during the six months ended
June 30, 1996. This increase was primarily due to the higher number of patients
enrolled in the Phase III clinical trial for THERAFECTIN(R) during the 1997
period as compared to the 1996 period. Enrollment in the trial, which began in
March 1996, was completed in March 1997 and the trial is expected to be
completed in August 1997 with results available at the end of September 1997.
Before any commercially viable product from THERAFECTIN(R) may be developed, and
any revenue generated therefrom, the Company currently expects that at least
$500,000 to $1.0 million of additional future expense will be necessary. There
can be no assurance, however, that the expenditure of these additional amounts
will result in the regulatory approval of any compounds or that such approval
will ever be able to be obtained by the Company. Moreover, if the current Phase
III trial for THERAFECTIN(R) provides unsatisfactory or disappointing results,
the Company may be required to write off all or some portion of the $3.5 million
asset value represented by the THERAFECTIN(R) technology acquired in the Merger
with Greenwich Pharmaceuticals, Inc. as reflected on the Company's balance
sheet.

            General and administrative expenses were $996,580 during the six
months ended June 30, 1997 as compared with $1,406,320 during the comparable
1996 period. This decrease was primarily due to (i) the incurrence, during the
1996 period, of contractual obligations totaling $175,000 associated with the
employment contract between the Company and its Chief Executive Officer and (ii)
lower professional services costs.

            Net interest income was $610,382 during the six months ended June
30, 1997 as compared with net interest income of $109,198 during the six months
ended June 30, 1996. Interest income totaled approximately $612,000 during the
1997 period as compared to approximately $436,000 during the comparable 1996
period. Interest expense totaled approximately $3,000 during the 1997 period as

                                       8

compared to approximately $327,000 in the comparable 1996 period. The higher
amount of interest income recognized during the 1997 period primarily related to
higher average cash balances associated with the Company raising net proceeds of
approximately $25.7 million from two private placements completed in the first
half of 1996. The interest expense incurred during the 1996 period related to
(i) the issuance of $2.175 million of notes payable during the first quarter of
1995, (ii) the issuance of $1.0 million of convertible subordinated debentures
during the fourth quarter of 1995, and (iii) the amortization of the debt
issuance costs associated with both financings. The debentures were converted
into common stock in February 1996 and the Company paid the remaining principal
on the notes payable at the beginning of the second quarter of 1996.

      Liquidity and Capital Resources
            Since its inception, the Company has satisfied its working capital
requirements from the sale of the Company's securities through private
placements. In January and February 1996, the Company raised approximately $20.7
million of net proceeds by completing a private placement of units consisting of
(i) shares of its Series A Convertible Preferred Stock and (ii) warrants to
purchase shares of the Company's common stock. In June 1996, the Company raised
approximately $5 million of net proceeds by completing a private placement of
500,000 shares of common stock (See Notes 8 and 9 of Notes to the Consolidated
Financial Statements in the Company's Annual Report on Form 10-K for the year
ended December 31, 1996). In the future, the Company's ability to meet, and the
level of, its working capital and capital requirements will depend on numerous
factors, including the progress of the Company's research and development
activities, the level of resources that the Company devotes to the
developmental, clinical, and regulatory aspects of its products, and the extent
to which the Company enters into collaborative relationships with pharmaceutical
and biotechnology companies.

            At June 30, 1997, the Company had available cash, cash equivalents
and short term investments of approximately $18.2 million and working capital of
approximately $16.9 million. The Company believes that the level of financial
resources available at June 30, 1997 will provide sufficient working capital to
meet its anticipated expenditures for more than the next twelve months. The
Company may raise additional capital in the future through collaboration
agreements with other pharmaceutical or biotechnology companies, debt financings
and equity offerings. There can be no assurance, however, that the Company will
be successful in such efforts or that additional funds will be available on
acceptable terms, if at all.
