             Notes to Consolidated Financial Statements (Unaudited)
                                 March 31, 2002

1.    Basis of Presentation

      The accompanying unaudited consolidated financial statements have been
      prepared in accordance with accounting principles generally accepted in
      the United States of America 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 accounting principles generally
      accepted in the United States of America 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, 2001
      included in the Company's Annual Report on Form 10-K.

2.    Net Loss Per Share

      Basic and diluted net loss per share available to common stockholders has
      been calculated by dividing net loss by the weighted average number of
      common shares outstanding during the period. All potential common shares
      have been excluded from the calculation of weighted average common shares
      outstanding since their inclusion would be anti-dilutive.

      Stock options and warrants to purchase approximately 9.2 million and 7.5
      million shares of common stock were outstanding at March 31, 2002 and
      2001, respectively, but were not included in the computation of diluted
      net loss per common share because they were anti-dilutive. The exercise of
      those stock options and warrants outstanding at March 31, 2002, which
      could generate proceeds to the Company of up to $39 million, could
      potentially dilute earnings per share in the future.

3.   Comprehensive Loss

     The Company had total comprehensive loss of $3,096,032 and $1,942,735 for
     the three months ended March 31, 2002 and 2001, respectively.

4.   Stockholders' Equity

     In March 2002, the Company completed a private placement of 1,599,568
     shares of common stock, which raised approximately $3.4 million in gross
     proceeds. In connection with the financing, the Company issued warrants to
     the investors to purchase 399,892 shares of common stock at an exercise
     price equal to $2.75 per share. In connection with this financing, the
     Company paid $271,772 in cash and issued a warrant to purchase 157,557
     shares of common stock at an exercise price equal to $2.75 per share to the
     placement agent.

5.   Accounting Pronouncements

     In January 2002, the Company adopted Statement of Financial Accounting
     Standard ("SFAS") No. 142, "Goodwill and Other Intangible Assets." SFAS No.
     142 requires that ratable amortization of goodwill be replaced with
     periodic tests of the goodwill's impairment and that intangible assets
     other than goodwill be amortized over their useful lives. The Company's
     adoption of SFAS No. 142 did not have a material effect on its financial
     statements.

     In January 2002, the Company adopted SFAS No. 144, "Accounting for the
     Impairment or Disposal of Long-Lived Assets," which addresses the financial
     accounting and reporting for the disposal of long-lived assets. The
     Company's adoption of SFAS No. 144 did not have a material effect on its
     financial statements.

Item 2.               Management's Discussion and Analysis
                of Financial Condition and Results of Operations
                                 March 31, 2002

     This Quarterly Report on Form 10-Q contains forward-looking statements.
Specifically, any statements contained herein that are not statements of
historical fact may be deemed to be forward-looking statements. Without limiting
the foregoing, the words "believes," "anticipates," "plans," "expects," and
similar expressions are intended to identify forward-looking statements. There
are a number of meaningful factors that could cause the Company's actual results
to differ materially from those indicated by any such forward-looking
statements. These factors include, without limitation, the duration and results
of clinical trials and their effect on the Food & Drug Administration ("FDA")
regulatory process, uncertainties regarding receipt of approvals for any
possible products and any commercial acceptance of such products, possible
difficulties with obtaining necessary patent protection, and uncertainties
regarding the outcome of any of the Company's collaborations or alliances with
third parties. Other factors include those set forth under the caption
"Forward-Looking Statements" in the Company's Annual Report on Form 10-K for the
year ended December 31, 2001 and the documents referred to under such caption.

Results of Operations

  Overview

     The Company is a biotechnology company engaged in the research and
development of novel therapeutic and diagnostic solutions for central nervous
system diseases. The Company also has programs in cancer and autoimmune
diseases. The Company expects that its research and development costs will
continue as the Company attempts to gain  regulatory approval for commercial
introduction of its proposed products. At  March 31, 2002, the Company is
considered a "development stage enterprise" as defined in Statement of Financial
Accounting Standards No. 7.

  Critical Accounting Policies

     There have been no material changes in the critical accounting policies
reported in the Company's Annual Report on Form 10-K for the year ended December
31, 2001.

  Three Months Ended March 31, 2002 and 2001

     The Company's net loss was $3,019,791 during the three months ended March
31, 2002 as compared with $2,121,737 during the three months ended March 31,
2001. Net loss per common share equaled $0.14 per share for the 2002 period as
compared to $0.10 per share for the 2001 period. The increased net loss in the
2002 period was primarily due to higher expenses across all components of
operations, including research and development, and general and administrative.
In addition, the Company realized lower levels of interest income and incurred
certain other non-operating expenses.

     Research and development expenses were $2,062,876 during the three months
ended March 31, 2002 as compared with $1,744,168 during the three months ended
March 31, 2001. The increase was primarily attributable to expenditures of
approximately $80,000 related to an ongoing clinical trial which was initiated
in December 2001 and approximately $130,000 in higher pre-clinical costs for
another of the Company's technologies.

     General and administrative expenses were $912,757 during the three months
ended March 31, 2002 as compared with $695,511 during the three months ended
March 31, 2001. The increase was

                                       6




primarily related to higher professional services costs, including approximately
$170,000 in higher legal fees incurred in connection with patent and
intellectual property efforts.

     Other expenses were $143,500 during the three months ended March 31, 2002
as compared with zero during the three months ended March 31, 2001. The increase
in 2002 was due to a non-cash charge related to an agreement the Company entered
into with a securityholder to modify the terms of certain warrants held by the
securityholder. The securityholder agreed to defer the date on which the
exercise price of the warrants would be reset. In return, the Company issued
additional warrants to the securityholder. The non-cash charge was based upon a
fair value calculation of the additional warrants issued to the securityholder
as determined under the Black-Scholes pricing model.

     Interest income was $99,342 during the three months ended March 31, 2002 as
compared with $317,942 during the three months ended March 31, 2001. The
decrease was primarily due to lower average cash, cash equivalent, and
short-term investment balances during the 2002 period as compared to the 2001
period.

Liquidity and Capital Resources

     Since its inception, the Company has primarily satisfied its working
capital requirements from the sale of the Company's securities through private
placements. These private placements have included the sale of preferred stock
and common stock, as well as notes payable and convertible debentures. Each
private placement has included the issuance of warrants to purchase common
stock. A summary of financings completed during the three years ended March 31,
2002 is as follows:

Date              Net Proceeds Raised      Securities Issued
- ----              -------------------      -----------------
March 2002        $2.9 million             Common stock

June 2000         $9.9 million             Common stock

September 1999    $7.4 million             Convertible debentures

     In the future, the Company's 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 technologies, and the
extent to which the Company enters into collaborative relationships with
pharmaceutical and biotechnology companies.

     At March 31, 2002, the Company had available cash, cash equivalents and
short-term investments of approximately $10.7 million and working capital of
approximately $8.8 million. The Company believes that the level of financial
resources available at March 31, 2002 will provide sufficient working capital to
meet its anticipated expenditures for the next twelve months. The Company may
raise additional capital in the future through collaborative agreements with
other pharmaceutical or biotechnology companies, debt financings and equity
offerings. There can be no assurance, however, that the Company will be
successful or that additional funds will be available on acceptable terms, if at
all.

     There have been no material changes in the commitments and contingencies
reported in the Company's Annual Report on Form 10-K for the year ended December
31, 2001.

Accounting Pronouncements

     In January 2002, the Company adopted Statement of Financial Accounting
Standard ("SFAS") No. 142, "Goodwill and Other Intangible Assets." SFAS No. 142
requires that ratable amortization of goodwill be replaced with periodic tests
of the goodwill's impairment and that intangible assets other than goodwill be
amortized over their useful lives. The Company's adoption of SFAS No. 142 did
not have a material effect on its financial statements.

     In January 2002, the Company adopted SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets," which addresses the financial
accounting and reporting for the disposal of long-lived assets. The Company's

statements.
