                               PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus. This
summary is not complete and may not contain all of the information that you
should consider before investing in the Common Stock. You should read the entire
prospectus carefully.

Cortex Pharmaceuticals, Inc.

     We are a biopharmaceutical company located in Irvine, California. Our goal
is to develop proprietary drugs designed to treat neurodegenerative diseases and
other neurological and psychiatric disorders. We were formed in Delaware in 1987
and since that date, we have devoted our resources to research and development
activities relating to several products that are at various developmental
stages. We have several license agreements with various research institutions,
which own approved and pending patents covering certain drugs and therapeutic
technologies.

     Since 1993, we have focused our research and development on the AMPA
receptor, a complex of proteins that is involved in most "excitatory"
communication between nerve cells in the human brain. We are developing several
chemical compounds, known as Ampakines(R), to enhance the activity of the AMPA
receptor. We believe that Ampakines may effectively treat deficiencies brought
on by a variety of diseases and disorders. In October 1994, we initiated human
safety studies with CX516 (Ampalex(R)). CX516 is a drug that has shown potential
for treating deficits of memory and cognition. These studies have involved
healthy young adult and elderly volunteers and, more recently, patients with
Alzheimer's disease and with schizophrenia. We are also investigating the use of
Ampakines to treat other disorders, such as depression.


     We believe that the quality of our science and technology provides us with
an advantage over our competitors in the discovery of innovative
pharmaceuticals. We do not, however, have the resources or expertise for later-
stage clinical development, manufacturing and worldwide marketing. Our
commercial development plans therefore involve partnering with larger
pharmaceutical companies for later-stage clinical testing, manufacturing and
global marketing of our proposed products. If we are successful in the pursuit
of this business strategy, we should be able to cover our costs over the next
few years, to maintain our focus on the research and development of innovative
pharmaceuticals and to eventually participate directly in the commercial
development of our products in the United States. Currently, we are seeking
collaborative or licensing arrangements with larger pharmaceutical companies
that will permit our proprietary products to complete clinical development and
that will provide access to the clinical trials management, manufacturing and
marketing expertise of those companies.


     In January 1999, we entered an exclusive license agreement with NV Organon
("Organon") of the Netherlands. In return for an upfront payment, we issued
Organon a license to develop and commercialize our proprietary Ampakine
technology for the treatment of schizophrenia. We also issued Organon a license
to explore the use of our Ampakines as a treatment for depression. We are
entitled to receive up to $3,000,000 per year for two years from the agreement
date, as long as we provide the agreed-upon levels of research. Additionally, we
are entitled to receive milestone payments and royalty payments on any worldwide
sales by Organon.


     Our offices and laboratories are located at 15241 Barranca Parkway, Irvine,
California,  92618 and our telephone number is (949) 727-3157.

     We hold registered trademarks on the names Ampalex and Ampakine. This
Prospectus also includes registered trademarks of other companies.


Risk Factors

An investment in the shares of Common Stock being offered by the Selling

                                  RISK FACTORS

     Investing in the Common Stock being offered by the Selling Stockholders is
very risky. You should be able to bear a complete loss of your investment. You
should carefully consider the following factors, in addition to the other
information contained in this Prospectus before making an investment decision.

Need for Additional Funds.

     Without further injections of capital, we anticipate that we have
sufficient funds to maintain our operations into May 2000. We will require
additional funds to continue our operations beyond that time. We cannot say with
any amount of certainty that we will be able to obtain the additional needed
funds on reasonable terms, or at all. If we decide to raise additional funds by
issuing more of our securities, stockholders at the time of issuance will
experience a dilution to the value of their securities.

     We anticipate receiving the first milestone from our agreement with Organon
during fiscal 2000. If we receive this milestone payment in or before May 2000,
we expect that we may sustain operations through December 2000. We cannot give
any assurance that the Company will receive the milestone during this timeframe,
or at all.

     If we are unable to obtain additional funds, we could lose our key
employees and could be required to abandon one or more of our product
development programs. In addition, we may be unable to meet our research
spending obligations under existing licensing agreements and may be unable to
continue our business operations.


     In addition to our agreement with Organon, we are presently seeking
collaborative or other arrangements with larger pharmaceutical companies to
provide for both our immediate and longer-term funding requirements. These
agreements would potentially provide us with additional funds in exchange for
exclusive or non-exclusive license or other rights to the technologies and
products that we are currently developing. Competition between biopharmaceutical
companies for these types of arrangements is intense. Although we have been
engaged in discussions with candidate companies for some time, we cannot give
any assurance that these discussions will result in an agreement or agreements
in a timely manner, or at all. Additionally, we cannot assure you that any
resulting agreement will generate sufficient revenues to offset our operating
expenses and longer-term funding requirements. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."




Reliance on N.V. Organon

     We are dependent on future payments from Organon to continue the
development and commercialization of our Ampakine technology.  Under the
agreement with Organon that we entered into in January 1999, we share the
research efforts. Organon has primary responsibility for developing and
commercializing Ampakines for use in the treatment of schizophrenia, with an
option to extend the rights to the treatment of depression.  The agreement
provides for an up-front payment by Organon of $2,000,000 and research support
payments of up to $3,000,000 per year for two years (subject to us providing
agreed-upon levels of research). The agreement also includes milestone payments,
plus royalty payments on a worldwide basis.  Under the terms of the agreement,
Organon has the right at any time to terminate the agreement upon four months'
prior notice.  In addition, Organon has the right to terminate the research and
development related to the agreement upon 30 days' prior notice in the event
that we materially breach the agreement and do not cure the breach within 60
days of receipt of a notice of breach from Organon. If Organon were to
discontinue its financial support, we might not be able to continue the
development of our Ampakine technology, and our financial condition would be
seriously impaired.  See "Business;" "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

<PAGE>

Development Stage Company; History of Losses.

     We are considered a "development stage" company because, since our
formation on February 10, 1987 through September 30, 1999, we have generated
only modest operating revenues and we have incurred net losses aggregating
$37,320,197. As of September 30, 1999, we had an accumulated deficit of
$39,352,036. We will require substantial additional funds to advance our
research and development programs, particularly if we decide to independently
conduct later-stage clinical testing and apply for regulatory approval of any of
our proposed products. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business."

Dependence on Strategic Alliances and Third Parties for Clinical Testing,
Manufacturing and Marketing.

     We do not have the resources, and do not presently intend, to conduct
later-stage human clinical trials or to manufacture our proposed products. We
are therefore seeking larger pharmaceutical company partners to conduct such
activities for most or all of our proposed products. In connection with our
efforts to secure additional corporate partners, we will seek to retain certain
co-promotional rights to our proposed products. These co-promotional rights will
allow us to market our products to selected medical specialists while our
corporate partner markets our products to the general medical market. We cannot
assure you that we will be able to enter into any partnering arrangements on
this or any other basis. In addition, we cannot assure you that we, or our
prospective corporate partners, can successfully introduce our proposed
products. We also face the risks that our products will be rejected by patients,
health care providers or insurance companies, or that our products cannot be
manufactured and marketed at prices that would permit us to operate profitably.
See "Business."

Technological Uncertainty; Early Stage of Product Development; No Assurance of
Regulatory Approvals.

     We cannot assure you that our research and development activities will
enable us to produce any products able to withstand competition. Our development
of each product is subject to the risks of failure commonly experienced in the
development of products based upon innovative technologies and the expense and
difficulty of obtaining approvals from regulatory agencies. All of our proposed
products are in the preclinical or early clinical stage of development and will
require significant additional funding for research, development and clinical
testing before we are able to submit them to any of the regulatory agencies for
clearances for commercial use.  We cannot assure you that we will be able to
license any technologies or proposed products or to complete successfully any of
our research and development activities.  Even if we do complete them, we cannot
assure you that we will be able to market successfully any of the products or
that we will be able to obtain the necessary regulatory approvals or that
customers will like our products.  We also face the risk that any or all of our
products will not work as intended or that they will be toxic, or that, even if
they do work and are safe, that our products will be uneconomical to manufacture
and market on a large scale.  We also face the risk that the rights of other
persons or entities will stop us from marketing any of our products or that
other persons or entities might develop and market a superior or equivalent
product. Due to the extended testing and regulatory review process required
before we can obtain marketing clearance, we do not expect to be able to
commercialize any therapeutic drug for at least five years, either directly or
through our corporate partners or licensees.  See "Business."

Limited Proprietary Rights; Uncertainty Associated With Patent Protection.

     Under our agreements with the Regents of the University of California, we
have exclusive rights to our Ampakine compounds for specified applications.
These rights are secured by patents or patent applications owned wholly by
others or by others as co-owners with us. Our existing agreements require us to
make certain minimum annual payments, meet certain milestones or diligently seek
to commercialize the underlying technology. Our failure to meet any of these
requirements could allow the other party to terminate that particular agreement.


                                       6
<PAGE>

     Our success will depend, in part, on our ability to get patent protection
for our products and processes in the United States and elsewhere. We have filed
and intend to continue to file patent applications as we need them. We cannot
assure you, however, that any additional patents will issue from any of these
applications or, if patents do issue, that the claims allowed will be
sufficiently broad to protect our technology. Also, we cannot assure you that
any patents issued to us or licensed by us can withstand challenges made by
others or that we will be able to protect our rights.

     If we are unable to obtain sufficient protection of our proprietary rights
in our products or processes prior to or after obtaining regulatory clearances,
our competitors may be able to obtain regulatory clearance and market competing
products by demonstrating the equivalency of their products to our products. If
they are successful at demonstrating the equivalency between the products, our
competitors would not have to conduct the same lengthy clinical tests that we
have conducted.

     We also rely on trade secrets and confidential information that we try to
protect by entering into confidentiality agreements with other parties. We
cannot assure you that any of the confidentiality agreements will be honored,
or, if breached, that we would have enough remedies to protect the confidential
information. Further, we cannot assure you that our competitors will not
independently learn our trade secrets or develop similar or superior
technologies. To the extent that our consultants, key employees or others apply
technological information independently developed by them or by others to our
projects, disputes may arise regarding the proprietary rights to such
information. We cannot assure you that such disputes will be resolved in favor
of the Company. See "Business -- Patents and Proprietary Rights."

Shares Eligible for Future Sale; Dilution.

     If all outstanding warrants and options are exercised prior to their
expiration, approximately 2.5 million additional shares of Common Stock could
become freely tradable without restriction. An aggregate of 11,025 shares of
Common Stock are issuable upon conversion of currently outstanding 9% Preferred
Stock and Series B Preferred Stock. On issuance such shares will be freely
tradable. All shares of Common Stock issuable upon exercise of the outstanding
warrants will be freely tradable under the Registration Statement of which this
Prospectus is part. Sales of substantial amounts of Common Stock in the public
market could adversely affect the prevailing market price of the Common Stock.
See "Description of Securities."

Intense Competition.

     Our business is characterized by intensive research efforts. Our
competitors include many companies, research institutes and universities that
are working in a number of pharmaceutical or biotechnology disciplines to
develop therapeutic products similar to those we are currently investigating.
Most of these competitors have substantially greater financial, technical,
manufacturing, marketing, distribution and/or other resources than us. In
addition, many of our competitors have experience in performing human clinical
trials of new or improved therapeutic products and obtaining approvals from the
FDA and other regulatory agencies. We have no experience in conducting and
managing later-stage clinical testing or in preparing applications necessary to
obtain regulatory approvals. Accordingly, it is possible that our competitors
may succeed in developing products that are safer or more effective than those
that we are developing and may obtain FDA approvals for their products faster
than we can. We expect that competition in this field will continue to
intensify.  See "Business--Competition."

Dependence Upon Key Personnel.

     We are highly dependent upon key management and technical personnel.
Competition for qualified employees among pharmaceutical and biotechnology
companies is intense. The loss of any of our key management or technical
personnel, or our inability to attract, retain and motivate the additional
highly-skilled employees and consultants that our business requires, could
substantially hurt our business and prospects. We cannot assure you that we will
be able to retain our existing personnel or attract additional qualified
employees when we need them. See "Business" and "Management."

                                       7

Dependence on Relationships with Consultants and the University of California,
Irvine.

     We depend upon our relationships with a number of academic consultants,
particularly Drs. Carl W. Cotman and Gary S. Lynch of the University of
California, Irvine ("UCI"). Drs. Cotman and Lynch play a role in guiding our
internal research. In addition, we sponsor preclinical research in Dr Lynch's
laboratories at UCI that is part of our product development and corporate
partnering profile. If our relationships with Dr. Lynch or UCI are disrupted,
our AMPA receptor research program could be adversely affected. We cannot assure
you that we would be able to conduct the sponsored research internally at
reasonable cost, or at all. Our agreements with our consultants, including those
with Drs. Cotman and Lynch, are generally terminable by the consultant on short
notice. See "Management."

Government Regulation.

     The FDA and other similar agencies in foreign countries have substantial
requirements for therapeutic products.  Such requirements often involve lengthy
and detailed laboratory, clinical and post-clinical testing procedures. It often
takes companies many years to satisfy these requirements, depending on the
complexity and novelty of the product. The review process is also extensive
which may delay the approval process even more. As yet, we have not obtained any
approvals to market our products. Further, we cannot assure you that the FDA or
other regulatory agency will grant us approval for any of our products on a
timely basis, if at all. Even if regulatory clearances are obtained, a marketed
product is subject to continual review, and later discovery of previously
unknown problems may result in restrictions on marketing or withdrawal of the
product from the market. See "Business--Government Regulation."


Lack of Listing on an Exchange or on the Nasdaq System; Restrictions on Our
Stock

     Our Common Stock is not listed on any exchange or on the Nasdaq System.
Our Common Stock is reported on the OTC Bulletin Board.  Because our shares are
not listed on any exchange or on the Nasdaq System, they are subject to the
regulations regarding trading in "penny stocks," which are those securities
trading for less than $5.00 per share.  The following is a list of the
restrictions on the sale of penny stocks:

     .  Prior to the sale of penny stock by a broker-dealer to a new purchaser,
the broker-dealer must determine whether the purchaser is suitable to invest in
penny stocks. To make that determination, a broker-dealer must obtain, from a
prospective investor, information regarding the purchaser's financial condition
and investment experience and objectives. Subsequently, the broker-dealer must
deliver to the purchaser a written statement setting forth the basis of the
suitability finding.

     .  A broker-dealer must obtain from the purchaser a written agreement to
purchase the securities. This agreement must be obtained for every purchase
until the purchaser becomes an "established customer."

     .  The Exchange Act requires that prior to effecting any transaction in any
penny stock, a broker-dealer must provide the purchaser with a "risk disclosure
document" that contains, among other things, a description of the penny stock
market and how it functions and the risks associated with such investment. These
disclosure rules are applicable to both purchases and sales by investors.

     .  A dealer that sells penny stock must send to the purchaser, within ten
days after the end of each calendar month, a written account statement including
prescribed information relating to the security.

      As a result of our securities not being listed on an exchange or the
Nasdaq System and the rules regarding penny stock transactions, your ability to
sell to a third party may be limited. We make no guarantee that our current
market-makers will continue to make a market in our securities, or that any
market for our securities will continue.

                                       8
<PAGE>

Product Liability and Insurance.

     Clinical testing, manufacturing and marketing of our products may expose us
to product liability claims. Although we have never been subject to a product
liability claim, we cannot assure you that there will not be any claims brought
against us in the future. Further, we cannot assure you that the coverage limits
of our insurance policies will be adequate or that one or more successful claims
brought against us would not have a material adverse effect upon our business,
financial condition and results of operations.

Volatility of Stock Price.



     We are in the biopharmaceutical industry and the market price of securities
of life sciences companies in general has been very unpredictable. See "Price
Range of Common Stock." Announcements by us or our competitors concerning
technological innovations, new products, proposed governmental regulations or
actions, developments or disputes relating to patents or proprietary rights,
public concern over the safety of therapeutic products and other factors that
affect the market generally could significantly impact our business and the
market price of our securities.

Dividends.

     Since our formation in 1987, we have not paid cash dividends on our Common
Stock. We do not anticipate paying any dividends on our Common Stock in the
future. Furthermore, the terms of the 9% Preferred Stock do not allow for the
payment of cash dividends unless we have paid the accrued and unpaid dividends
on the 9% Preferred Stock in full. As of September 30, 1999, accrued and unpaid
dividends on the 9% Preferred Stock were $23,513. See "Dividend Policy."

Anti-Takeover Provisions.

     Certain provisions of our Certificate of Incorporation could make it more
difficult for a third party to acquire control of our business, even if such
change in control would be beneficial to our stockholders. Our Certificate of
Incorporation allows our Board of Directors to issue up to 549,100 shares of
preferred stock without stockholder approval. Any such issuance could make it
more difficult for a third party to acquire our business and may adversely
affect the rights of our stockholders. See "Description of Securities."

                                USE OF PROCEEDS

We will not receive any of the proceeds from the Selling Stockholder's sale of
their shares of Common Stock.

                                DIVIDEND POLICY

    The Company has never paid cash dividends on its Common Stock and does not
anticipate paying such dividends in the foreseeable future. The Company
currently intends to retain any future earnings for use in the Company's
business. The outstanding shares of 9% Preferred Stock bear a fixed dividend of
$0.09 per share per annum, which accrues in equal semi-annual installments on
June 15th and December 15th of each year, which dividends must be paid in full
before any dividends can be paid on the Common Stock. As of September 30, 1999,
accrued and unpaid dividends on the 9% Preferred Stock were $23,513. The payment
of future dividends, if any, will be determined by the Board of Directors in
light of conditions then existing, including the Company's financial condition
and requirements, future prospects, restrictions in financing agreements,
business conditions and other factors deemed relevant by the Board of Directors.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the
Financial Statements and Notes thereto appearing elsewhere in this report and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in the Company's 1999 Annual Report on Form 10-KSB.

Introductory Note

     This discussion and analysis contains certain forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934, and the Company intends that such
forward-looking statements be subject to the safe harbors created thereby. These
forward-looking statements relate to (i) future research plans and expenditures,
(ii) potential collaborative arrangements, and (iii) the need for, and
availability of, additional financing.

     The forward-looking statements included herein are based on current
expectations that involve a number of risks and uncertainties. These forward-
looking statements are based on assumptions regarding the Company's business and
technology, which involve judgments with respect to, among other things, future
scientific, economic and competitive conditions, and future business decisions,
all of which are difficult or impossible to predict accurately and many of which
are beyond the control of the Company. Although the Company believes that the
assumptions underlying the forward-looking statements are reasonable, any of the
assumptions could prove inaccurate and, therefore, there is no assurance that
the results contemplated in forward-looking statements will be realized and
actual results may differ materially. In light of the significant uncertainties
inherent in the forward-looking information included herein, the inclusion of
such information should not be regarded as a representation by the Company or
any other person that the objectives or plans of the Company will be achieved.

Results of Operations

     From inception (February 10, 1987) through September 30, 1999, the
Company's revenue has consisted of (i) $7,549,000 of license fees and research
and development funding, (ii) net interest income aggregating $1,695,000, and
(iii) $261,000 of grant revenue.

     In January 1999, the Company entered into a research collaboration and
exclusive worldwide license agreement with NV Organon ("Organon"), a
pharmaceutical business unit of Akzo Nobel (The Netherlands). The agreement will
allow Organon to develop and commercialize the Company's proprietary Ampakine
technology for the treatment of schizophrenia and, upon Organon's election, for
the treatment of depression. In connection with the agreement, the Company
received a $2,000,000 upfront licensing payment. The agreement includes research
support payments of up to $3,000,000 per year for two years (subject to Cortex
providing agreed-upon levels of research) and milestone payments, plus royalty
payments on worldwide sales.

     Subsequent to September 30, 1999, the Company received a quarterly research
support payment of $893,000. This amount exceeds the payments received for prior
quarters, reflecting the increase in the Company's staff dedicated to the
alliance. Future quarterly research support is expected to average
$750,000.

   From inception (February 10, 1987) through September 30, 1999, the Company
has sustained losses aggregating $37,320,000. Continuing losses are anticipated
over the next several years, as the Company's ongoing operating expenses will
only be offset, if at all, by research support payments and possible milestone
payments from its research collaboration with Organon, or under planned
strategic alliances that the Company is seeking with other pharmaceutical
companies for the clinical development, manufacturing and marketing of its
products. The nature and timing of payments to Cortex under the Organon
agreement or other planned strategic alliances, if and when entered into, are
likely to significantly affect the Company's operations and financing activities
and to produce substantial

                                       14
<PAGE>


period-to-period fluctuations in reported financial results. Over the longer
term, the Company will require successful commercial development of its products
by Organon or its other prospective partners to attain profitable operations
from royalties or other product-based revenues.

     The Company believes that inflation and changing prices have not had a
material impact on its ongoing operations to date.


Fiscal Years ended June 30, 1999 and 1998

     For the year ended June 30, 1999, the Company's loss from operations was
$1,630,000 compared to a loss from operations of $5,462,000 for the prior year,
with the improvement attributable to revenues from the license and research
collaboration with Organon.

     Research and development expenses decreased to $3,380,000, or by 16%,
during the year ended June 30, 1999 compared to the prior year. Most of the
decrease related to the timing of Phase I/IIa human clinical testing of the
Company's lead compound, Ampalex, in patients with Alzheimer's disease and in
patients with schizophrenia.

     General and administrative expenses were $1,401,000 for the year ended June
30, 1999, decreasing 12% from the prior year. Most of this decrease represents
reduced spending for office supplies, travel and the annual report. The decrease
also reflects the prior year expense for the estimated value of a warrant issued
to Alkermes in connection with the restructured note payable agreement.

Three-month periods ended September 30, 1999 and 1998

     The net loss for the three-month period ended September 30, 1999 of
$291,000 compares with a net loss of $1,186,000 for the corresponding prior year
period. Revenues from the license and research collaboration with Organon were
responsible for the improvements in the current year period (See Note 5 of Notes
to Financial Statements).

     Research and development expenses decreased from $839,000 to $752,000, or
by 10%, during the three-month period ended September 30, 1999 compared to the
corresponding prior year period. The decrease reflects lower spending for
sponsored research and the timing of both technology access payments and Phase
I/IIa human clinical testing of Ampalex(R). Future costs for the clinical
testing of Ampakines in patients with schizophrenia will be borne by
Organon.

     For the three-month period ended September 30, 1999, general and
administrative expenses of $367,000 were materially consistent with expenses of
$355,000 for the corresponding prior year period.

Liquidity and Capital Resources; Plan of Operation

     From inception (February 10, 1987) through September 30, 1999, Cortex has
funded its organizational and research and development activities primarily from
the issuance of equity securities, with net proceeds aggregating $35,749,000. An
additional $3,600,000 in research and license payments was received from
Alkermes, Inc. ("Alkermes") in 1992 and 1993 in connection with a development
and license agreement with that firm. Net interest income from inception through
September 30, 1999 was $1,695,000.

     Research and licensing payments received in connection with the agreement
with Organon (See Note 5 of Notes to Financial Statements) totaled $3,819,000
through September 30, 1999. The agreement includes research support payments of
up to $3,000,000 per year for two years (subject to Cortex providing agreed-upon
levels of research), milestone payments based on clinical development of the
licensed technology and royalties on worldwide sales.

                                       15

     As of September 30, 1999, the Company had cash and cash equivalents
totaling $289,000 and a working capital deficit of $987,000. In comparison, as
of June 30, 1999, the Company had cash and cash equivalents of $909,000 and a
working capital deficit of $742,000. The decreases represent amounts required to
fund operating losses. Subsequent to September 30, 1999, the Company received
quarterly research support of $893,000 related to its agreement with
Organon.

     The Company leases approximately 30,000 square feet of research laboratory,
office and expansion space under an operating lease that expires May 31, 2004.
The commitments under the lease agreement for the years ending June 30, 2000,
2001, 2002, 2003 and 2004 total $255,000, $310,000, $353,000, $368,000 and
$356,000, respectively. From inception (February 10, 1987) through September 30,
1999, expenditures for furniture, equipment and leasehold improvements
aggregated $2,214,000.

     In connection with the settlement in October 1995 of a license dispute with
Alkermes, the Company issued to Alkermes a $1,000,000 three-year promissory note
accruing interest semi-annually at the then federal funds rate. In February
1998, the terms of the note were restructured to include a principal payment of
$200,000 upon signing of the restructuring agreement. The balance of the note
and accrued interest were payable in October 1999 or upon the consummation of a
corporate partnership between Cortex and a larger pharmaceutical company,
whichever was earlier. With the signing of the license agreement with Organon,
the note and accrued interest became due and payable. In July 1999, the terms of
the note were restructured to include a principal and interest payment of
$250,000 and monthly payments of $50,000 from August 1999 through January 2000.
The balance of the note and accrued interest are payable on or before February
28, 2000.


     The Company is currently in advanced discussions with potential corporate
partners.  Based upon the anticipated timing of a resulting strategic alliance,
the Company may be able to pay Alkermes the balance of the note and accrued
interest due by the end of February, as agreed.  Because there is no assurance
that a partnership will be completed prior to the note's due date, or at all,
the Company contacted Alkermes regarding a possible extension of the terms of
the note.  In February 2000, Alkermes agreed to extend the note's payment terms,
if necessary.  If the Company needs to extend the note, the Company has agreed
to continue to pay Alkermes $50,000 per month with the balance of the note and
accrued interest due on May 31, 2000.  Additionally, if the terms are extended,
the Company has agreed to issue to Alkermes a five-year warrant to purchase
50,000 shares of Cortex common stock, at a price derived from the fair market
value of the stock as of February 28, 2000.


     As of September 30, 1999, Cortex had 27,500 outstanding shares of 9%
cumulative convertible preferred stock, which accrue cumulative semi-annual
dividends at an annual rate of $0.09 per share. To conserve capital for
operations, the Company has elected not to distribute the dividends that have
accrued from June 1990. Accrued and unpaid dividends as of September 30, 1999
were $23,513.

     Over the next twelve months the Company is committed to $603,000 of funding
for sponsored research in academic laboratories. Remaining commitments for
current Phase I/IIa clinical studies on the Company's Ampakine compounds are not
significant.

     As of September 30, 1999, Cortex had a total of 22 full-time research and
administrative employees. Neither significant increases to staffing nor
significant investments in plant or equipment are planned for the upcoming
year.

     Assuming that the Company extends the terms of the note payable to
Alkermes, Cortex anticipates that its existing cash and cash equivalents and the
expected research support payments from Organon will be sufficient to satisfy
its capital requirements into May 2000. Without any payments from additional
corporate partnerships or milestone payments from the
Organon agreement, additional funds will be required to continue op erations
beyond that time.

     The Company is in advanced discussions with potential corporate partners
and anticipates that an alliance from these discussion may be completed before
May 2000. The Company anticipates receiving its first milestone payment from its
existing corporate partner, Organon, in before May 2000. With receipt of the
projected Organon quarterly research support and the milestone payment during
the estimated timeframe, the Company expects to have sufficient cash to fund
operations through calendar 2000. With the additional funds from an anticipated
upfront payment from a potential corporate partnership, the Company expects to
have sufficient cash to fund operations into early calendar 2001. Because there
is no assurance that the milestone will be received as estimated, or at all, or
that the Company will secure additional corporate partnerships, the Company may
raise additional capital through the sale of debt or equity securities. Given
the current adverse market conditions for biopharmaceutical companies, there is
no assurance that funds will be available on favorable terms, or at all. If
equity securities are issued to raise additional funds, dilution to existing
shareholders is likely to result.

     The Company's Common Stock previously traded on the Nasdaq SmallCap Market
under the symbol "CORX." Because the Company did not meet certain of the
standards for continued listing, the Company's Common

                                       16
<PAGE>


Stock was delisted from Nasdaq on March 17, 1999. As a result, effective March
18, 1999, the Company's Common Stock began trading in the over-the-counter
market on the OTC "Electronic Bulletin Board."

     In order to provide for both its immediate and longer-term spending
requirements, the Company is presently seeking additional collaborative or other
arrangements with larger pharmaceutical companies. Under these agreements, it is
intended that such companies would provide capital to the Company in exchange
for exclusive or non-exclusive license or other rights to certain of the
technologies and products that the Company is developing. Competition for such
arrangements is intense, however, with a large number of biopharmaceutical
companies attempting to secure alliances with more established pharmaceutical
companies. Although the Company is in advanced discussions with candidate
companies, there is no assurance that an agreement or agreements will arise from
these discussions in a timely manner, or at all, or that revenues that may be
generated thereby will offset operating expenses sufficiently to reduce the
Company's short and longer-term funding requirements.

     The Company's proposed products are in the preclinical or early clinical
stage of development and will require significant further research, development,
clinical testing and regulatory clearances. They 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 the
proposed products will be found to be ineffective or toxic, or otherwise fail to
receive necessary regulatory clearances; that the proposed products, although
effective, will be uneconomical to market; that third parties may now or in the
future hold proprietary rights that preclude the Company from marketing them; or
that third parties will market superior or equivalent products. Accordingly, the
Company is unable to predict whether its research and development activities
will result in any commercially viable products or applications. Further, due to
the extended testing and regulatory review process required before marketing
clearance can be obtained, the Company does not expect to be able to
commercialize any therapeutic drug for at least five years, either directly or
through its current or prospective corporate partners or licensees. There can be
no assurance that the Company's proposed products will prove to be safe or
effective or receive regulatory approvals that are required for commercial sale.

                                    BUSINESS

Overview

     Cortex Pharmaceuticals, Inc. ("Cortex" or the "Company") is a development
stage enterprise that was organized in 1987 to engage in the discovery,
development and commercialization of innovative pharmaceuticals for the
treatment of neurodegenerative diseases and other neurological and psychiatric
disorders. Since 1993, the primary effort at Cortex has been centered on
developing products that affect the AMPA-type glutamate receptor, a complex of
proteins that is involved in most "excitatory" communication between nerve cells
in the human brain. Cortex is developing a family of chemical compounds, known
as Ampakines, that enhance the activity of this receptor. Cortex believes that
Ampakines hold promise for correcting deficits brought on by a variety of
diseases and disorders that are known, or thought, to involve depressed
functioning of pathways in the brain that use glutamate as a
neurotransmitter.

     The Ampakine program addresses large potential markets. Accordingly, the
Company's commercial development plan involves partnering with larger
pharmaceutical companies for research, development, clinical testing,
manufacturing and global marketing of its proposed products. The Company may
retain the right to eventually co-promote Ampakines for selected indications in
the United States. If the Company is successful in the pursuit of this
partnering strategy, it may be in a position to contain its costs over the next
few years, to maintain its focus on the research and early development of novel
pharmaceuticals (where it believes that it has the ability to compete) and
eventually to participate more fully in the commercial development of its
proposed products in the United States. In January 1999, the Company entered a
research collaboration and exclusive worldwide license agreement with NV Organon
("Organon"), a subsidiary of Akzo Nobel (The Netherlands). The agreement will
enable Organon to develop and commercialize the Company's Ampakine technology
for the treatment of schizophrenia and, upon Organon's election, for the
treatment of depression. Cortex continues to seek collaborative or licensing
arrangements with other pharmaceutical companies. These arrangements may permit
other applications of the Ampakines to be advanced into later stages of clinical
development and may provide access to the extensive clinical trials management,
manufacturing and marketing expertise of such companies. The Company may not be
able to secure such arrangements on favorable terms, or at all, and its products
may not be successfully developed and approved for marketing by government
regulatory agencies.

     In the fiscal years ended June 30, 1999 and 1998, the Company's
expenditures on research and development were $3,380,000 and $4,007,000,
respectively, with the decrease attributable to the timing of Phase I/IIa human
clinical testing of CX516 (Ampalex) in patients with schizophrenia and in
patients with Alzheimer's disease.

AMPA Receptor Program
- ---------------------

     In June 1993, Cortex licensed a new class of compounds -- the Ampakines --
from the University of California. Ampakines facilitate the activity of the AMPA
receptor, which binds the neurotransmitter glutamate. The Ampakines interact in
a highly specific manner with the AMPA receptor in the brain, lowering the
amount of neurotransmitter required to generate a response, and increasing the
magnitude of the response to any given amount of glutamate. It is hoped that
this selective amplification of the normal glutamate signal will eventually find
utility in the treatment of neurological diseases and disorders characterized by
depressed functioning of brain pathways that utilize glutamate as a
neurotransmitter.

     It is well known that synaptic connections, including those that utilize
glutamate, decline with age. Thus, disorders such as mild cognitive impairment
associated with aging may be amenable to treatment with Ampakines. Two prominent
diseases that may benefit from AMPA receptor-directed therapeutics are
schizophrenia and Alzheimer's disease. The Company and its collaborators have
also obtained encouraging preliminary results in animal models of depression,
sexual dysfunction and depressed endocrine function.

Schizophrenia

     Schizophrenia is a major health care problem. The worldwide incidence of
the disease is approximately one percent, regardless of ethnic, cultural or
socioeconomic status. On any given day, approximately 100,000 of the estimated
two million U.S. patients with schizophrenia are in public mental
hospitals.

     Schizophrenia typically develops in late adolescence or early adulthood and
is best understood as a syndrome, or collection of symptoms. These are generally
characterized as positive symptoms (delusions and hallucinations), negative
symptoms (social withdrawal and loss of emotional responsiveness) and cognitive
symptoms (disordered thought and attention deficits).

     The first "wonder drugs" for schizophrenia, the so-called neuroleptics or
conventional anti-psychotics, were developed in the 1950s and 1960s. These
drugs, such as chlorpromazine and haloperidol, helped to reduce the positive
symptoms of the disease and greatly reduced the need for chronic
hospitalization. However, these drugs, which are still in use today, are
characterized by troublesome and occasionally life-threatening side effects. One
of the most common side effects of conventional anti-psychotics is EPS or
"extrapyramidal signs," which include restlessness and tremors. EPS side effects
have a strongly negative impact on quality of life and tend to lead to poor
patient compliance with medication.

     More recently, a new type of anti-psychotic agent, referred to as atypical
due to the virtual lack of EPS side effects, has been developed. Clozapine was
the first such drug. It was initially studied in the 1970s, but clinical trials
were halted due to the risk of a fatal blood disorder known as agranulocytosis
and a dose-dependent risk of seizures. Clozapine was reintroduced in the 1980s,
with approval by the FDA for use in patients who cannot be adequately treated
with typical neuroleptics, either because of lack of efficacy or side effects.
Risperidone and olanzapine are other recent clozapine-like anti-psychotics
without agranulocytosis side effects.

     The newer atypical agents achieve good control of positive symptoms,
partial control of negative symptoms and better patient compliance with
medication due to lower levels of EPS side effects. However, schizophrenia
clinicians agree that there are still substantial side effects and that the
cognitive symptoms of schizophrenia are not greatly improved by any available
agent. The persistence of cognitive symptoms prevents all but a few patients
with schizophrenia from successfully reintegrating into society.

     Schizophrenia has long been thought to have its biochemical basis in an
overactivity of dopamine pathways projecting into an area of the brain known as
the striatum. More recently, a developing body of evidence suggests that
schizophrenia also involves an underactivity of glutamate pathways projecting
into the same area. Cortex is therefore studying whether Ampakines, which
increase current flow through the AMPA subtype of glutamate receptor, might have
relevance to the treatment of schizophrenia.

     In late 1995, Cortex announced the discovery that an Ampakine reduced
stereotypic behavior (mechanical repetition of posture or movement) in rats that
had been injected with methamphetamine. Reduction of methamphetamine-induced
stereotypic behavior is widely used for initial screening of anti-psychotic
drugs. Scientists at both the University of California, Irvine and Cortex have
since extended this finding to include additional Ampakines. Further, Cortex
scientists have demonstrated that Ampakines in combination with either
conventional or atypical anti-psychotic drugs have additive or synergistic
effects in this model system.

     In January 1999, the Company entered into an exclusive worldwide license
agreement with Organon. The agreement will enable Organon to develop and
commercialize Cortex's proprietary Ampakine technology for the treatment of
schizophrenia and to explore it in the area of depression. The agreement
includes an upfront payment of $2,000,000, research and development payments of
up to $3,000,000 per year for two years, and milestone payments, plus royalty
payments on worldwide sales. The Company hopes that the agreement with Organon
will provide an accelerated program to bring the Ampakines to market for
schizophrenia and possibly depression, if proven safe and effective in clinical
trials.

                                       19

     Shortly thereafter, in April 1999 the Company reported preliminary results
from a study with CX516 in patients with schizophrenia being treated with
clozapine. This Phase I/IIa clinical trial, conducted at Massachusetts General
Hospital, was designed primarily as a safety study. Clinical and psychological
testing was also included in an attempt to obtain a preliminary indication that
CX516 may effect the psychological parameters that likely contribute to symptoms
of the disease, particularly the cognitive symptoms that have thus far been
resistant to treatment. Preliminary results indicate that CX516 is reasonably
safe in combination with clozapine and improves performance on several tests of
verbal learning, memory, problem solving and distractability. The improvements
noted in CX516-treated patients appeared to persist for a period of time after
cessation of treatment.

     A second similar study to assess the affect of CX516 as a `mono' therapy in
patients with schizophrenia was initiated at the National Institutes of Health
in Bethesda, Maryland. Because of slow patient enrollment, the Company has since
elected to discontinue this study. The Company intends that further clinical
testing of the Ampakines in patients with schizophrenia will be conducted by its
corporate partner, Organon. Data obtained from the testing performed at
Massachusetts General Hospital should be very helpful in the design of such
trials. Cortex is pleased with the progress of the Organon research
collaboration and anticipates receiving its first milestone payment from the
agreement before the end of 1999.

Deficits of Memory and Cognition -- Alzheimer's Disease

     Impairment of memory and cognition is a serious health care problem that is
growing as the elderly population continues to increase. While not fatal (except
when associated with diseases such as Alzheimer's disease), the incidence and
prevalence of cognitive deficits increase inexorably with age. Many elderly
individuals are confined to nursing homes because of psychological
disorientation and functional difficulties. Pharmaceuticals to alleviate
deficits in memory and cognition could potentially enable these elderly
individuals to remain independent longer.


     Although disease and physiological malfunctions are thought to be the
fundamental cause of severe mental decline, age itself is a contributory factor,
with the human brain losing about 10% of its weight over a normal life span. In
the cerebral cortex, a great deal of the communication between neurons is
mediated by receptors for the neurotransmitter glutamate, including a subtype
known as the AMPA receptor. AMPA receptors and synapses decline in number with
aging, on average by 25-30% between the ages of 25 and 65, making it more
difficult for information to pass through and between areas of the cerebral
cortex. Therefore a potential corrective approach to alleviate age-related
cognitive deficits is to enhance the activity of the remaining functional AMPA
receptors.

     Alzheimer's disease is the best known destroyer of memory, currently
afflicting some four million Americans. With the aging of our population, the
number of people in the U.S. with Alzheimer's disease is expected to double over
the next two decades unless a treatment is found. According to the Alzheimer's
Association, Alzheimer's disease is already the third most expensive disease in
the U.S. (after heart disease and cancer), with an estimated annual cost to
society of $100 billion and a lifetime cost per patient of $174,000. The impact
of an effective treatment, even a symptomatic one, would be enormous.


     It is in the early stages of Alzheimer's disease -- the first few years --
that Cortex believes Ampakines may play a valuable role, enhancing the
effectiveness of the brain cells that have not yet succumbed to the disease.
This may help to alleviate the memory and cognitive deficits that make up the
early symptoms. There is also a possibility that treatment with Ampakines may
slow the progression of Alzheimer's disease. The reason for this is that brain
cells, or neurons, require continued input from other brain cells to remain
alive. As neurons die, other neurons begin to lose their inputs, hastening their
own death. Ampakines may slow the rate at which functional levels of input from
other neurons are lost. Research also suggests that Ampakines may increase the
production of neurotrophic factors that are known to be protective for nerve
cells.

     One of the most compelling of the animal studies conducted to date with the
Ampakines involved an assessment of the effects on memory performance in middle-
aged rats. A number of researchers have demonstrated that

                                       20
<PAGE>


healthy middle-aged rats have significant deficits in memory performance when
compared to younger animals. This provides an animal model for age-associated
memory impairment in humans. In a study published in Synapse, the authors
conducted research involving a maze task with middle-aged and young adult rats.
The middle-aged rats showed striking deficits in performance when compared with
the young adult animals. When given an Ampakine, the performance of the middle-
aged rats improved to levels equivalent to those found in young animals.

     Three human clinical safety studies have been completed with CX516
("Ampalex") in healthy volunteers. In all three studies, CX516 was safe and
well-tolerated on acute oral administration and, importantly, statistically-
significant positive effects on memory performance were seen in healthy
volunteers.

     The initial study, conducted by AFB Parexel in Berlin involved single
administrations of drug or placebo to a total of 48 healthy young adult
volunteers, ranging in age from 18 to 35. The trial was double-blinded and
placebo-controlled, and involved administering a single dose of drug, in capsule
form, to each volunteer. Several dosages of drug were tested and at all dosage
levels, the drug was safe and well-tolerated. In addition, analysis of
psychological data that was collected revealed a highly statistically
significant positive effect on a test of memory performance that involved recall
of a list of nonsense syllables.

     The second trial, at the same clinical site in Berlin, involved 30 healthy
elderly volunteers, aged 65 to 76, each of whom was administered a single oral
dose of drug or placebo. In this double-blinded trial, Ampalex was again found
to be safe and well-tolerated. The elderly volunteers were also given the same
nonsense syllable memory test that had been given to the young volunteers in the
first study. In the absence of drug, the elderly volunteers' memory was
substantially worse than that of the young volunteers. In the presence of drug,
a statistically significant positive effect on memory performance was observed.
Several of the elderly volunteers receiving the highest dosage of Ampalex scored
at or above the average score achieved by the young volunteers in the earlier
study.

     The third study, at the Karolinska Hospital in Stockholm, Sweden, involved
administration of CX516 to healthy young adults under double-blind, placebo-
controlled conditions. This five-day study involved administration of placebo on
days 1, 4 and 5 and drug on days 2 and 3, with psychological testing conducted
on each day. Ampalex was safe and well-tolerated by all volunteers receiving
drug, with no adverse events reported. Statistically significant improvements in
performance on several measures of learning and memory were noted in the group
that received CX516.

     After these encouraging results, Cortex initiated a Phase I/IIa study in
patients experiencing deficits of memory and cognition due to Alzheimer's
disease. The double-blind, placebo-controlled dose escalation study, which is
being conducted at the National Institutes of Health in Bethesda, Maryland,
involves administration of CX516 to an eventual total of 16 to 20 patients for
up to 28 consecutive days. To date, 15 patients have been enrolled in this
study, with enrollment of an additional five patients anticipated.

     While preliminary indications of desired effects on memory and cognition
may be obtained from this study, psychological testing of patients with
Alzheimer's disease is subject to a high level of variability. Full-scale Phase
II studies designed to achieve significance on broad psychological scales will
require larger numbers of patients. Cortex is seeking a larger pharmaceutical
company partner for further development of Ampakines for  the potential
treatment of Alzheimer's disease.

Calpain Inhibitor Program

     Calpain is a protease, a protein that digests other proteins. It is
involved in a variety of biological processes throughout the body and has been
implicated in the pathology of several diseases and disorders.


     The Company's first target for calpain inhibitor therapeutics was brain
damage following stroke. A stroke is a vascular event causing localized damage
to the brain. There are two general categories of stroke: ischemic stroke,


                                       21
<PAGE>


which is due to a blockage of blood flow, and hemorrhagic stroke, which involves
a blood vessel bursting in the brain. In either case, the insult to the brain is
often immediately life-threatening and initiates a cascade of molecular events
that may lead to permanent brain damage.




     In 1990 and 1991, Cortex established laboratory models of ischemia and used
them to identify a range of calpain inhibitor compounds that appeared to have
the potential to block brain damage due to stroke and other ischemic events. In
January 1992, Cortex entered into a Development and License Agreement, amended
in October 1992, (the "Alkermes Agreement") with Alkermes, Inc. ("Alkermes"), a
larger neuroscience company. Cortex granted to Alkermes an exclusive worldwide
license, with a right to of acute and chronic neurodegenerative diseases and
disorders of the nervous system.

     Subsequently, Cortex shifted its emphasis to calpain inhibitor research
outside the nervous system. The Cortex 1993 annual report included a discussion
of the Company's research in cerebral vasospasm, which involved reversal of an
existing spasm of blood vessels in the brain. In October 1993, Alkermes notified
the Company that Alkermes believed that it had rights to this indication under
the Alkermes Agreement. In November 1993, Alkermes filed an action in U.S.
District Court in Massachusetts alleging that the Company had breached the
Alkermes Agreement by developing calpain inhibitors for cerebral vasospasm.

     In October 1995, the Company and Alkermes agreed to a settlement of the
dispute. Alkermes agreed to dismiss its action against Cortex and to relinquish
all rights previously granted them by the Company, as well as rights to related
technologies developed by Alkermes. In connection with the settlement, the
Company issued to Alkermes a $1,000,000 non-transferable, three-year promissory
note accruing interest semi-annually at the federal funds rate. The Company also
committed to pay Alkermes a graduated royalty on calpain inhibitor development
proceeds, as defined and subject to certain limitations. In February 1998, the
terms of the note were restructured to include a principal payment of $200,000
upon signing of the new agreement. The balance of the note and accrued interest
was payable in October 1999 or upon consummation of a corporate partnership
between Cortex and a larger pharmaceutical company, whichever was earlier. In
connection with the restructuring agreement, the Company issued to Alkermes a
five-year warrant to purchase 75,000 shares of Common Stock at an exercise price
of $1.55 per share. With the signing of the license agreement with Organon (see
Note 5 of Notes to Financial Statements), the note became due and payable. In
July 1999, the terms of the note were restructured to include a principal and
interest payment of $250,000 and monthly payments of $50,000 from August 1999 to
January 2000. The balance of the note and accrued interest is due and payable by
February 28, 2000. In connection with this restructuring agreement, the Company
agreed to issue to Alkermes a five-year warrant to purchase 100,000 shares of
Common Stock at an exercise price derived from the fair market value of the
Company's Common Stock. As part of the restructuring agreement, because the
balance was not paid by December 31, 1999, the Company agreed to issue to
Alkermes another five-year warrant to purchase 50,000 shares of the Common Stock
at $0.76 per share. The exercise price for this warrant represents the average
of the closing prices of the Company's Common Stock for the 30 trading days
preceding December 31, 1999.

     If necessary, the Company may extend the due date of the note by issuing to
Alkermes another five-year warrant to purchase 50,000 shares of Cortex common
stock. The exercise price for this warrant will be derived from the fair market
value of the stock as of February 28, 2000. If the due date is extended, the
Company agrees to continue to pay Alkermes $50,000 per month, with the balance
of the note and accrued interest due May 31, 2000.

     Cortex has subsequently shifted more of its resources from its calpain
inhibitor program to its Ampakine technology platform. As part of the Company's
emphasis on its Ampakine program, Cortex canceled its licensing agreement with
Georgia Tech Research Corporation related to the Company's calpain inhibitor
technology during the year ended June 30, 1999.

Manufacturing

     Cortex has no experience in manufacturing pharmaceutical products and
relies, and presently intends to rely, on the manufacturing and quality control
expertise of contract manufacturing organizations or prospective corporate
partners. There is no assurance that the Company will be able to enter
arrangements for manufacturing of its proposed products on favorable terms.

                                       22
<PAGE>

Marketing

     The Company has no experience in the marketing of pharmaceutical products
and does not anticipate having the resources to distribute and broadly market
any products that it may develop. The Company will therefore continue to seek
commercial development arrangements with other pharmaceutical companies for its
proposed products. In entering into such arrangements, the Company may seek to
retain the right to co-promote products for certain indications in North
America. The Company's worldwide licensing agreement with Organon (see Note 5 of
Notes to Financial Statements) does not provide Cortex with co-promotional
rights. There is no assurance that the Company will be able to enter into co-
promotional arrangements in connection with its other licensing activities, or
that co-promotional rights will lead to greater revenues for the Company.

Technology Rights and Collaborative Agreements

AMPA Receptor Modulating Compounds

     In 1993, Cortex entered into an agreement with the Regents of the
University of California, under which Cortex secured exclusive commercial rights
to AMPA receptor modulating compounds (Ampakines) for the treatment of deficits
of memory and cognition. The agreement was subsequently amended to include
additional indications. The Company paid an initial license fee and is obligated
to make additional payments, including license maintenance fees and patent
expense reimbursements creditable against future royalties, over the course of
initiating and conducting human clinical testing and obtaining regulatory
approvals. When and if sales of licensed products commence, the Company will pay
royalties on net sales.



Patents and Proprietary Rights

     The Company is aggressively pursuing patent protection of its technologies.
Cortex owns or has exclusive rights (within its areas of product development) to
approximately 15 issued or allowed U.S. patents and a number of additional U.S.
patent applications and their international counterparts.

     In April 1999, Cortex received a patent that covers the Company's Ampakines
- -- as well as compounds made by others -- for the treatment of memory and
cognition. It allows Cortex and its licensees to exclude others in the United
States from making and selling AMPA-receptor modulating compounds for the
treatment of memory or dementia, including Alzheimer's disease. The coverage
also extends to psychiatric conditions including depression, obsessive
compulsive disorder, attention deficit disorder, and phobic disorders. In 1998,
Cortex received a United States patent that contained a similarly broad claim
for any AMPA-modulating compound to treat schizophrenia.

     There is no assurance that patents, whether already issued or issuing in
the future in connection with current or future patent applications, will afford
effective protection against competitors with similar technology. There is also
no assurance that any patents issued or licensed to Cortex will not be infringed
upon or designed around by others. Further, since issuance of a patent does not
guarantee the right to practice the claimed invention, there is no assurance
that others will not obtain patents that the Company would then need to license
or design around in order to practice its patented technologies, or that Cortex
would be able to obtain licenses that might be required to practice these
technologies due to patents of others on reasonable terms. Additionally, any
unpatented manufacture, use or sale of the Company's technology, processes or
products may infringe on patents or proprietary rights of others, and the
Company may be unable to obtain licenses or other rights to these other
technologies that may be required for commercialization of the Company's
proposed products or processes.

     Cortex relies to a certain extent upon unpatented proprietary technology
and may determine in some cases that its interests would be better served by
reliance on trade secrets or confidentiality agreements rather than patents. No
assurance is made that others will not independently develop substantially
equivalent proprietary information and techniques or otherwise gain access to or
disclose such technology. In addition, there is no assurance that Cortex can

                                       23
<PAGE>

meaningfully protect its rights in such unpatented proprietary technology or
that others will not wrongfully obtain such technology.

     If Cortex is unable to obtain strong protection of its proprietary rights
in its products or processes prior to or after obtaining regulatory clearance,
whether through patents, trade secrets or otherwise, competitors may be able to
market competing products by obtaining regulatory clearance through
demonstration of equivalency to the Company's products, without being required
to conduct the same lengthy clinical tests conducted by the Company.

Government Regulation

     In order to test, produce and market human therapeutic products in the
United States, mandatory procedures and safety standards established by the Food
and Drug Administration ("FDA") must be satisfied. Obtaining FDA approval is a
costly and time-consuming process. Although Cortex has initiated Phase I
(safety) testing in Europe, it has not yet filed a Notice of Claimed
Investigational Exemption for a New Drug ("IND") with the FDA for testing in the
United States. The Company is conducting Phase I/IIa studies in the U.S. with
CX516 in Alzheimer's disease patients and in patients with schizophrenia under
INDs filed by its clinical collaborators. It is the Company's intent that
Organon, or other pharmaceutical company partner or partners that the Company is
seeking, will pursue the required regulatory approvals to conduct clinical tests
in the United States and elsewhere.

     Clinical trials are normally conducted in three phases. Phase I trials are
concerned primarily with safety of the drug, involve fewer than 100 subjects,
and may take from six months to over a year. Phase II trials normally involve a
few hundred patients and are designed primarily to demonstrate effectiveness in
treating or diagnosing the disease or condition for which the drug is intended,
although short-term side effects and risks in people whose health is impaired
may also be examined. Phase III trials may involve up to several thousand
patients who have the disease or condition for which the drug is intended, to
approximate more closely the conditions of ordinary medical practice. Phase III
trials are also designed to clarify the drug's benefit-risk relationship, to
uncover less common side effects and adverse reactions, and to generate
information for proper labeling of the drug. The FDA receives reports on the
progress of each phase of clinical testing, and may require the modification,
suspension, or termination of clinical trials if an unwarranted risk is
presented to patients. The FDA estimates that the clinical trial period of drug
development can take up to ten years, and averages five years. With certain
exceptions, once clinical testing is completed, the sponsor can submit a New
Drug Application ("NDA") for approval to market a drug. The FDA's review of an
NDA can also be lengthy.

     Therapeutic products that may be developed and sold by the Company outside
the United States will be subject to regulation by the various countries in
which they are to be distributed. In addition, products manufactured in the
United States that have not yet been cleared for domestic distribution will
require FDA approval in order to be exported to foreign countries for
distribution there.

     There is no assurance that any required FDA or other governmental approval
will be granted or, if granted, will not be withdrawn. Governmental regulation
may substantially delay or prevent the marketing of the Company's proposed
products, or cause the Company to undertake additional procedures, which may be
both costly and lengthy, and thereby furnish a competitive advantage to the
competitors of the Company or its licensees.

     Cortex does not have the financial and other resources to conduct the
clinical testing and other procedures required to obtain approval to market its
products. Accordingly, the Company will be dependent upon entering into
partnerships or other collaborative arrangements with third parties with the
required resources to obtain the needed approvals. Along with its agreement with
Organon, Cortex intends to enter into license or other arrangements with other
pharmaceutical companies under which those companies would conduct the required
clinical trials and seek FDA approval for most or all of its proposed products.
There is no assurance that Cortex will be able to enter into such arrangements
on favorable terms, or at all, or that such arrangements will ultimately result
in obtaining the necessary governmental approvals.

                                       24
<PAGE>

Competition

     The pharmaceutical industry is characterized by rapidly evolving technology
and intense competition. Many companies of all sizes, including both major
pharmaceutical companies and specialized biotechnology companies, are engaged in
activities similar to those of Cortex. A large number of drugs intended for the
treatment of Alzheimer's disease, schizophrenia, depression and other
neurological and psychiatric diseases and disorders are on the market or in the
later stages of clinical testing. For example, approximately 15 drugs are in
development in the U.S. for schizophrenia. In addition, over 25 drugs are under
clinical investigation in the U.S. for the treatment of Alzheimer's disease. The
Company's competitors have substantially greater financial and other resources
and larger research and development staffs. Larger pharmaceutical company
competitors also have significant experience in preclinical testing, human
clinical trials and regulatory approval procedures.

     In addition, colleges, universities, governmental agencies and other public
and private research organizations will continue to conduct research and are
becoming more active in seeking patent protection and licensing arrangements to
collect license fees, milestone payments and royalties in exchange for license
rights to technology that they have developed, some of which may be directly
competitive with that of the Company. These institutions also compete with
companies such as Cortex in recruiting highly qualified scientific personnel.

     The Company expects technological developments in the neuropharmacology
field to continue to occur at a rapid rate and expects that competition will
remain intense as advances continue to be made. Although the Company believes,
based on the technical qualifications, expertise and reputations of its
Scientific Directors, consultants and other key scientists, that it will be able
to compete in the discovery and early clinical development of therapeutics for
neurological and psychiatric disorders, the Company does not have the resources,
and does not presently intend, to compete with major pharmaceutical companies in
clinical testing, manufacturing and marketing.

Product Liability Insurance

     The clinical testing, manufacturing and marketing of the Company's products
may expose the Company to product liability claims, against which the Company
maintains liability insurance. Although the Company has never been subject to a
product liability claim, there is no assurance that such claims will not be
brought in the future, that the coverage limits of the Company's insurance
policies will be adequate or that one or more successful claims brought against
the Company would not have a material adverse effect upon the Company's
business, financial condition and results of operations.

Employees

     As of December 31, 1999, Cortex had 23 full-time employees and had engaged
4 part-time Ph.D.-level scientific consultants. Of the 23 full-time employees,
19 are engaged in research and development and 4 are engaged in management and
administrative support. The Company also sponsors a substantial amount of
research in academic laboratories.

Facilities

     The Company leases approximately 30,000 square feet of office, research
laboratory and expansion space under an operating lease that expires May 31,
2004. Current monthly rent on these facilities is approximately $20,000. The
Company believes that this facility will be adequate for its research and
development activities for at least the next three years.

Legal Proceedings

The Company is not a party to any material legal proceedings.

                             CERTAIN TRANSACTIONS

     The Company's Restated Certificate of Incorporation provides that, pursuant
to Delaware law, directors of the Company shall not be liable for monetary
damages for breach of the directors' fiduciary duty of care to the Company and
its stockholders. This provision does not eliminate the duty of care, and in
appropriate circumstances equitable remedies such as injunctions or other forms
of non-monetary relief remain available under Delaware law. In addition, each
director continues to be subject to liability for breach of the director's duty
of loyalty to the Company, for acts or omissions not in good faith or involving
intentional misconduct, for knowing violations of law, for actions leading to
improper personal benefit to the director and for payment of dividends or
approval of stock repurchases or redemptions that are unlawful under Delaware
law. The provision also does not affect a director's responsibility under any
other law, such as the federal securities laws. The Company has entered into
Indemnification Agreements with each of the officers and directors that obligate
the Company to indemnify them as permitted by applicable law.

     See "Employment and Consulting Agreements" for a description of certain
arrangements and transactions with executive officers and directors.

stock options held by employees and officers, directors and consultants to the
Company, 3,667 shares for issuance upon conversion of the 9% Preferred Stock,
7,359 shares for issuance upon conversion of the Series B Preferred Stock,
800,000 shares for issuance upon exercise of the Series A Warrants, 420,306
shares for issuance upon exercise of the Vector Warrants and 106,195 shares for
issuance upon exercise of the Swartz Warrants.

Common Stock

     Holders of shares of Common Stock are entitled to one vote per share held
of record on all matters submitted to a vote of stockholders, including the
election of directors. The holders are entitled to receive dividends when, as
and if declared by the Board of Directors, in its discretion, out of funds
legally available therefor, subject to preferences that may be applicable to any
outstanding shares of Preferred Stock. See "Dividend Policy." In the event of a
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to share ratably in all of the assets of the Company
remaining after payment of liabilities and after payment of any preferential
amounts to which holders of shares of the 9% Preferred Stock, the Series B
Preferred Stock and any other series of Preferred Stock that may be outstanding
in the future, may be entitled. Holders of Common Stock have no preemptive or
other subscription rights, and there are no conversion rights or redemption or
sinking fund provisions with respect to such shares. All of the outstanding
shares of Common Stock are, and the shares of Common Stock when issued will be,
fully paid and nonassessable.

Warrants

     In December 1993, in connection with the closing of a private placement of
2,750,000 shares of Common Stock, for which Vector acted as placement agent, the
Company issued to Vector a warrant to purchase 274,200 shares of Common Stock at
a price of $9.375 per share at any time through November 30, 1998. As
consideration for Vector's assistance in reaching the settlement with Alkermes,
this warrant was canceled and reissued as a new warrant to purchase 363,113
shares of the Company's Common Stock at $3.47 per share, as adjusted and subject
to further adjustment, at any time through January 15, 2000. This warrant
expired unexercised on January 15, 2000.

                                       34

     As consideration for its agreement to provide financial advisory services
related to corporate finance transactions and corporate partnering activities,
as amended and extended in November 1994, Vector was issued a six-year non-
redeemable warrant to purchase 57,193 shares of the Company's Common Stock at
$3.06 per share, subject to adjustment under certain circumstances. Warrants to
purchase 8,169 shares of the Company's Common Stock vested immediately, and
warrants to purchase 24,512 shares of the Company's Common Stock will vest upon
the consummation of each strategic alliance, as defined, when and as secured by
Vector.

     In connection with the December 1995 private placement of 160 shares of
Series C Preferred Stock, the Company issued to the placement agent for the
transaction a five-year non-redeemable warrant to purchase 106,195 shares of
Common Stock at a price of $2.825 per share subject to adjustment under certain
circumstances. The warrants contain cashless exercise provisions and include
piggyback registration rights.

     In connection with the June 1997 private placement of 400 shares of Series
A Preferred Stock, the Company issued to the eleven participating institutional
investors four-year non-redeemable warrants to purchase an aggregate of 800,000
shares of Common Stock at a price of $3.08 per share, subject to adjustment
under certain circumstances.

     In connection with the February 1998 restructuring of the note payable to
Alkermes, Inc., the Company issued to Alkermes a five-year warrant to purchase
75,000 shares of Common Stock at an exercise price of $1.55 per share,
representing the average of the high and low sale prices of Cortex Common Stock
as reported on the Nasdaq SmallCap Market on the date of the restructuring.

    In connection with the July 1999 restructuring of the note payable to
Alkermes, Inc., the Company agreed to issue to Alkermes a five-year warrant to
purchase 100,000 shares of common stock at an exercise price derived from the
fair market value of the Company's common stock. In accordance with the
restructured terms, in December 1999 the Company agreed to issue to Alkermes a
five-year warrant to purchase 50,000 shares of the Company's common stock. The
exercise price for this warrant is $0.76 per share, representing the fair
market value of the Company common stock for the 30 trading days preceding the
issuance date.

Preferred Stock

     The holders of the 9% Preferred Stock are not entitled to vote for the
election of directors or upon any other matter presented to the stockholders,
except as and to the extent provided by applicable law. The holders of the
9% Preferred Stock are entitled to receive cumulative dividends, from and after
June 15, 1989, at the rate of $.09 per share per annum, out of funds legally
available therefor, when and as declared by the Board of Directors. Upon any
liquidation, dissolution or winding up of the Company, or any merger or
consolidation of the Company or other transaction in which more than 50% of the
Company's voting power is transferred (except for an issuance of the Company's
securities), the holders of the 9% Preferred Stock are entitled to receive an
amount equal to $1.00 per share plus accrued and unpaid dividends. The holders
of the 9% Preferred Stock are not entitled to share in assets remaining after
such preference is satisfied. The Company has the right at any time to redeem
the 9% Preferred Stock, in whole or in part, upon not less than 30 days' nor
more than 60 days'written notice, at a price of $1.00 per share.

     Each share of 9% Preferred Stock is convertible at any time at the option
of the holder thereof into approximately 0.1333 shares of Common Stock, at an
effective conversion price of $7.50 per share, subject to adjustment under
certain circumstances. Upon conversion of 9% Preferred Stock, accrued and unpaid
dividends pertaining thereto do not convert to Common Stock, but rather are
credited to additional paid-in capital.

     The holders of Series B Preferred Stock are not entitled to vote for the
election of directors or upon any other matter presented to the stockholders,
except as and to the extent provided by applicable law. In the event of any
liquidation, dissolution, winding-up or other distribution of the assets of the
Company, holders of Series B Preferred Stock are entitled to receive, after
payment of the full liquidation preference to holders of 9% Preferred Stock, an
amount equal to $0.6667 per share of Series B Preferred Stock. The Company has
the right to redeem the Series B Preferred Stock for $0.6667 per share. Each
share of Series B Preferred Stock is convertible at any time at the option of

                                       35
<PAGE>

the holder thereof into approximately 0.09812 shares of Common Stock at an
effective conversion price of $6.795 per share, subject to adjustment under
certain circumstances.



     The Restated Certificate of Incorporation of the Company authorizes the
issuance of 5,000,000 shares of Preferred Stock, of which 549,100 shares remain
undesignated. The Board of Directors, within the limitations and restrictions
contained in the Restated Certificate of Incorporation and without further
action by the Company's stockholders, has the authority to issue this
undesignated Preferred Stock from time to time in one or more series and to fix
the number of shares and the relative rights, conversion rights, voting rights,
rights and terms of redemption, liquidation preferences and any other
preferences, special rights and qualifications of any such series. If shares of
Preferred Stock with voting rights are issued, such issuance could affect the
voting rights of the holders of the Company's Common Stock by increasing the
number of outstanding shares entitled to vote and by the creation of class or
series voting rights. In addition, any further issuance of Preferred Stock
could, under certain circumstances, have the effect of delaying or preventing a
change in control of the Company and may adversely affect the rights of holders
of Common Stock. Other than the shares of 9% Preferred Stock and Series B
Preferred Stock, there are no shares of Preferred Stock currently issued and
outstanding and the Company has no present plans to issue any additional shares
of Preferred Stock or to establish or designate any new series of Preferred
Stock.

Transfer Agent and Warrant Agent

     American Stock Transfer and Trust Company, 40 Wall Street, New York, New
York, 10005 serves as Transfer Agent for the Common Stock, 9% Preferred Stock
and Series B Preferred Stock of the Company.

                                    PLAN OF DISTRIBUTION

     The Company has been advised by each Selling Stockholder that the Selling
Stockholder may sell its Shares from time to time in transactions on the OTC
Bulletin Board in negotiated transactions, by writing options on the Shares or
by a combination of these methods, at fixed prices that may be changed, at
market prices at the time of sale, at prices related to market prices or at
negotiated prices. The Selling Stockholders may effect these transactions by
selling the Shares to or through broker-dealers, who may receive compensation in
the form of discounts, concessions or commissions from the Selling Stockholders
or the purchasers of the Shares for whom the broker-dealer may act as an agent
or to whom they may sell the Shares as a principal, or both. The compensation to
a particular broker-dealer may be in excess of customary commissions.

     The Selling Stockholders and broker-dealers who act in connection with the
sale of the Shares may be deemed to be "underwriters" within the meaning of the
Securities Act, and any commissions received by such broker-dealers and profits
on any resale of the Shares as a principal may be deemed to be underwriting
discounts and commissions under the Securities Act.


                                 LEGAL MATTERS

     The validity of the securities offered hereby will be passed upon for the
Company by Stradling Yocca Carlson & Rauth, a Professional Corporation, Newport

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS


The Stockholders and Board of Directors
Cortex Pharmaceuticals, Inc.

We have audited the accompanying balance sheets of Cortex Pharmaceuticals, Inc.
(a development stage enterprise) as of June 30, 1999 and 1998, and the related
statements of operations, stockholders' equity and cash flows for each of the
two years in the period ended June 30, 1999 and for the period from inception
(February 10, 1987) through June 30, 1999. 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 generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
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 financial statements referred to above present fairly, in
all material respects, the financial position of Cortex Pharmaceuticals, Inc. (a
development stage enterprise) at June 30, 1999 and 1998, and the results of its
operations and its cash flows for each of the two years in the period ended June
30, 1999 and for the period from inception (February 10, 1987) through June 30,
1999, in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1, the Company is
in the development stage and realization of the Company's assets is dependent
upon future events, the outcome of which is indeterminable. Additionally,
successful completion of the Company's development program and its transition,
ultimately, to attaining profitable operations is dependent upon obtaining
additional financing adequate to support the Company's cost structure.
Accordingly, these conditions raise substantial doubt about the Company's
ability to continue as a going concern. The financial statements do not include
any adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

Cortex Pharmaceuticals, Inc.
(A development stage enterprise)
NOTES TO FINANCIAL STATEMENTS

Period from inception (February 10, 1987) through September 30, 1999

All information as of September 30, 1999, for the three-month periods ended
September 30, 1999 and 1998, and for the period from inception (February 10,
1987) through September 30, 1999 is unaudited. In the opinion of management, all
adjustments (consisting only of normal recurring accruals) considered necessary
for a fair presentation have been included. Operating results for the three-
month period ended September 30, 1999 are not necessarily indicative of the
results that may be expected for the fiscal year ending June 30, 2000.

Note 1 -- Business and Summary of Significant Accounting Policies

Business -- Cortex Pharmaceuticals, Inc. (the "Company") was formed to engage in
the discovery, development and commercialization of innovative pharmaceuticals
for the treatment of neurodegenerative diseases and other neurological and
psychiatric disorders. Since its formation in 1987, the Company has been engaged
in research and early clinical development activities.

Basis of Presentation; Development Stage Enterprise -- The accompanying
financial statements have been prepared assuming that the Company will continue
as a going concern. This basis of accounting contemplates the recovery of the
Company's assets and the satisfaction of its liabilities in the normal course of
business. As of September 30, 1999, the Company had an accumulated deficit of
$39,352,036, net capital deficiency of $451,211 and negative working capital of
$987,326. Due to the Company's recurring losses and net capital deficiency,
there can be no assurance that the Company will be able to obtain additional
operating capital, which may impact the Company's ability to continue as a going
concern. The accompanying financial statements do not include any adjustments to
reflect the possible future effects on the recoverability and classification of
assets of the amounts and classification of liabilities that may result from the
possible inability of the Company to continue as a going concern.

From inception through September 30, 1999, the Company has generated only modest
operating revenues and has incurred losses aggregating $37,320,197. Successful
completion of the Company's development program and its transition, ultimately,
to attaining profitable operations is dependent upon obtaining additional
financing adequate to fulfill its research and development activities, and
achieving a level of revenue adequate to support the Company's cost structure.
There is no assurance that the Company will be successful in these areas.

In January 1999, the Company entered into a research collaboration and exclusive
worldwide license agreement with NV Organon ("Organon"), a subsidiary of Akzo
Nobel (Note 5). The agreement will enable Organon to develop or commercialize
the Company's Ampakine(R) technology for the treatment of schizophrenia and, at
Organon's election, for the treatment of depression. The Company is seeking
collaborative arrangements with other pharmaceutical companies for other
applications of the Ampakine compounds, under which such companies would provide
additional capital to the Company in exchange for exclusive or non-exclusive
license or other rights to certain of the technologies and products that the
Company is developing. Competition for corporate partnering arrangements with
major pharmaceutical companies is intense, with a large number of
biopharmaceutical companies attempting to arrive at such arrangements.
Accordingly, although the Company is in discussions with candidate companies,
there is no assurance that an agreement will arise from these discussions in a
timely manner, or at all, or that any agreement that may arise from these
discussions will successfully reduce the Company's short or longer-term funding
requirements.

To supplement its existing resources, the Company may need to raise additional
capital through the sale of debt or equity. There is no assurance that such
funds will be available on favorable terms, or at all and if additional funds
are raised by issuing equity securities, dilution to existing stockholders is
likely to result.

                                      F-11

Cash Equivalents -- The Company considers all highly liquid short-term
investments with maturities of less than three months when acquired to be cash
equivalents.

Furniture, Equipment and Leasehold Improvements -- Furniture, equipment and
leasehold improvements are recorded at cost and are being depreciated on a
straight-line basis over the lesser of their estimated useful lives, ranging
from five to ten years, or the life of the lease, as appropriate.

Net Loss per Share -- Net loss per share is computed based on the weighted
average number of common shares outstanding and includes preferred stock
dividends. Shares issuable upon conversion of preferred stock and upon exercise
of outstanding stock options and warrants are not included since the effects
would be anti-dilutive. For purposes of computing net loss per share, preferred
stock dividends include dividends that actually accrued and `imputed dividends'
for preferred stock issued with a nondetachable beneficial conversion feature
near the date of issuance. Imputed dividend represents the aggregate difference
between the conversion price and the fair market value of the common stock as of
the date of issuance of the preferred stock, without regard to the actual date
upon which the preferred stock may be converted.

New Accounting Standard -- In June 1997, the Financial Accounting Standards
Board issued SFAS No. 130, "Reporting Comprehensive Income," effective for
fiscal years beginning after December 15, 1997. SFAS No. 130 requires the
reporting of all components of comprehensive income, including net income, in
the financial statements in the period in which the components are recognized.
Comprehensive income is defined as the change in equity during a period from
transactions and other events and circumstances from non-owner sources. Net
income and other comprehensive income, including foreign currency translation
adjustments and unrealized gains and losses on investments, shall be reported
net of their related tax effect to arrive at comprehensive income. Because
comprehensive loss was not different than net loss, adoption of SFAS No. 130 did
not have an impact on the Company's financial statements.

Employee Stock Options -- The Company has elected to follow Accounting
Principles Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25),
in accounting for its employee stock options because the alternative fair value
accounting provided under Statement of Financial Accounting Standards No. 123,
"Accounting for Stock -Based Compensation" (SFAS 123), requires use of option
valuation models that were not developed for use in valuing employee stock
options. According to APB 25, no compensation expense is recognized since the
exercise price of the Company's stock options equals the market price of the
underlying stock on the date of grant.

Research and Development Costs -- All costs related to research and development
activities are treated as expenses in the period incurred.

Use of Estimates -- The preparation of financial statements in conformity with
generally accepted accounting principles 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. Actual results could differ from those estimates.

Reclassifications -- Certain previously reported amounts have been reclassified
to conform with the June 30, 1999 presentation.

Note 3 -- Redeemable Preferred Stock

Series A Convertible Preferred Stock ("Series A Preferred") at June 30, 1998
consisted of 250 shares of 400 shares originally issued in a two-tranche private
placement in June 1997. The Series A Preferred was convertible at an effective
conversion price derived from the lowest of the dollar volume weighted average
trading prices of the Company's common stock for each of the five trading days
immediately preceding the conversion date ("Average Stock Price"). The effective
conversion price was equal to 80% of the Average Stock Price if the Average
Stock Price was greater than $2.50 per share at the time of conversion; $2.00
per share if the Average Stock Price was less than $2.50 but greater than $2.10
per share; or 95% of the Average Stock Price if the Average Stock Price was less
than or equal to $2.10 per share. The conversion rate was subject to adjustment
at the rate of six percent per annum based on the length of the period from
issuance of the Series A Preferred until its conversion. As of June 30, 1999,
all outstanding shares of Series A Preferred had been converted into an
aggregate of 6,105,276 shares of the Company's common stock at effective
conversion prices ranging from $0.30 to $2.17 per share of common stock. Imputed
dividends of $1,012,493 related to the private placement were recorded for the
year ended June 30, 1997.


Note 4 -- Stockholders' Equity

Preferred Stock

The Company has authorized a total of 5,000,000 shares of preferred stock, par
value $0.001 per share, of which 1,250,000 shares have been designated as 9%
Cumulative Convertible Preferred Stock (non-voting, "9% Preferred"); 3,200,000
shares have been designated as Series B Convertible Preferred Stock (non-voting,
"Series B Preferred"); 500 shares have been designated as Series D Convertible
Preferred Stock (non-voting, "Series D Preferred"); 400 shares have been
designated as Series A Convertible Preferred Stock (non-voting, "Series A
Preferred"); and 549,100 shares are presently undesignated and may be issued
with such rights and powers as the Board of Directors may designate.

The 9% Cumulative Convertible Preferred Stock as of September 30, 1999, June 30,
1999 and June 30, 1998 consisted of 27,500, 27,500 and 35,000 shares,
respectively, of an original 1,250,000 shares of 9% Preferred issued in a 1988
private placement. Each share of 9% Preferred is convertible into approximately
0.1333 shares of common stock at an effective conversion price of $7.50 per
share of common stock, subject to adjustment under certain circumstances, such
as stock splits or stock dividends. Cash dividends on the 9% Preferred accrue
semi-annually on June 15th and December 15th at the rate of $0.09 per share per
annum. In order to conserve capital for operations, the Company has elected not
to distribute the dividends that have accrued from June 15, 1990. Upon
conversion of 9% Preferred, accrued and unpaid dividends are credited to
additional paid-in capital. Accrued and unpaid dividends as of September 30,
1999, June 30, 1999 and June 30, 1998 were $23,513, $23,513, and

                                      F-13
<PAGE>

$26,775, respectively. The Company may redeem the 9% Preferred at any time at a
price of $1.00 per share, an amount equal to its liquidation preference, upon
not less than 30 nor more than 60 days' notice.

Series B Convertible Preferred Stock as of September 30, 1999, June 30, 1999 and
June 30, 1998 consisted of 75,000, 75,000 and 150,000 shares, respectively, of
Series B Preferred issued in a May 1991 private placement. Each share of Series
B Preferred is convertible into approximately 0.09812 shares of common stock at
an effective conversion price of $6.795 per share of common stock, subject to
adjustment under certain circumstances such as stock splits or stock dividends.
The Series B Preferred may be redeemed by the Company at a price of $0.6667 per
share, an amount equal to its liquidation preference, at any time upon 30 days'
notice. The liquidation preference of the Series B Preferred is subordinate to
that of the 9% Preferred.

Series C Convertible Preferred Stock originally consisted of 160 shares issued
in a private placement in December 1995. As of June 30, 1997, all outstanding
shares of Series C Preferred had been converted into 1,517,611 shares of common
stock. The relative effective conversion prices ranged from $2.33 to $2.83, as
computed in accordance with a formula that was indexed to the average bid price
of the Company's common shares.

Series D Convertible Preferred Stock originally consisted of 400 shares issued
in a three-tranche private placement initiated in October 1996 and completed in
February 1997. As of June 30, 1997, all outstanding shares of Series D Preferred
had been converted into an aggregate of 1,433,437 shares of the Company's common
stock. The effective conversion prices ranged from $2.06 to $3.35 per share, as
computed in accordance with a formula that was indexed to the average bid price
of the Company's common shares. During the year ended June 30, 1997, imputed
dividends aggregating $879,672 were recorded in connection with the three
tranches.

Common Stock and Common Stock Purchase Warrants

In connection with the December 1995 private placement of 160 shares of Series C
Preferred Stock, the Company issued the placement agent for the transaction a
five-year non-redeemable warrant to purchase 106,195 shares of common stock at a
price of $2.825 per share, subject to adjustment under certain circumstances.
The warrants contain cashless exercise provisions and include piggyback
registration rights.

In connection with the June 1997 private placement of 400 shares of Series A
Preferred Stock, the Company issued to the eleven participating institutional
investors four-year non-redeemable warrants to purchase an aggregate of 800,000
shares of common stock at a price of $3.08 per share, subject to adjustment
under certain circumstances.

In connection with the restructuring of the note payable to Alkermes, Inc. (Note
6) in February 1998, the Company issued to Alkermes a five-year warrant to
purchase 75,000 share of common stock at an exercise price of $1.547 per share,
representing the average of the high and low sale prices of Cortex common stock
as of the date of the restructuring.

In connection with the restructuring of the note payable to Alkermes, Inc. (Note
6) in July 1999, the Company agreed to issued to Alkermes a five-year warrant to
purchase 100,000 shares of common stock at an exercise price derived from the
fair market value of the Company's common stock. In accordance with the
restructuring agreement, because the balance of the note and accrued interest
were not paid by December 31, 1999, the Company agreed to issue to Alkermes an
additional five-year warrant to purchase 50,000 shares of common stock at an
exercise price of $0.76 per share. The exercise price for this warrant
represents the average of the closing prices reported for the Company's common
stock for the 30 trading days preceding December 31, 1999.

As of September 30, 1999, the Company had reserved an aggregate of 3,667 shares
of common stock for issuance upon conversion of the outstanding 9% Preferred
Stock; 7,359 shares for issuance upon conversion of the Series B Preferred
Stock; 1,401,501 shares for issuance upon exercise of warrants; and 1,439,497
shares for issuance upon exercise of outstanding stock options.

Stock Option and Stock Purchase Plans

Employee/Director Option Plan -- The Company's 1989 Incentive Stock Option,
Nonqualified Stock Option and Stock Purchase Plan provided for the granting by
the Company of options and rights to purchase up to an aggregate of 700,000
shares of the Company's authorized but unissued common stock (subject to
adjustment under certain circumstances, such as stock splits, recapitalizations
and reorganizations) to directors, officers and other employees of the Company.
The exercise price of nonqualified stock options and the purchase price of stock
offered under this plan, which terminated February 2, 1999, was at least 85% of
the fair market value of the common stock on the date of grant. The exercise
price of incentive stock options was at least equal to the fair market value of
the common stock on the date of grant. As of September 30, 1999 and June 30,
1999, there were no options outstanding under this plan.

Consultant Plan -- The Company's 1989 Special Nonqualified Stock Option and
Stock Purchase Plan provided for the granting by the Company of options and
rights to purchase up to an aggregate of 400,000 shares of the Company's
authorized but unissued common stock (subject to adjustment under certain
circumstances, such as stock splits, recapitalizations and reorganizations) to
consultants to the Company. The exercise price of nonqualified stock options and
the purchase price of stock offered under this plan, which terminated February
2, 1999, was at least 50% of the fair market value of the common stock on the
date of grant. As of September 30, 1999 and June 30, 1999, options to purchase
an aggregate of 2,000 shares of common stock were outstanding under this plan.

1996 Stock Incentive Plan -- The Company's 1996 Stock Incentive Plan ("1996
Plan") provides for the granting of options and rights to purchase up to an
aggregate of 3,298,058 shares of the Company's authorized but unissued common
stock (subject to adjustment under certain circumstances, such as stock splits,
recapitalizations and reorganizations) to qualified employees, officers,
directors, consultants and other service providers. No further options will be
granted under the Company's earlier stock option and stock purchase plans. The
exercise price of nonqualified stock options and the purchase price of stock
offered under the 1996 Plan, which terminates October 25, 2006, must be at least
85% of the fair market value of the common stock of the date of grant. The
exercise price of incentive stock options must be at least equal to the fair
market value of the common stock on the date of grant. Each non-employee
director (other than those who serve on the Board of Directors to oversee an
investment in the Company) is automatically granted options to purchase 15,000
shares of common stock upon commencement of service as a director and additional
options to purchase 6,000 shares of common stock on the date of each Annual
Meeting of Stockholders. Non-employee directors who serve on the Board of
Directors to oversee an investment in the Company receive options to purchase
7,500 shares of common stock upon commencement of service as a director and
additional options to purchase 3,000 shares of common stock on the date of each
Annual Meeting of Stockholders. These nonqualified options have an exercise
price equal to 100% of the fair market value of the common stock on the date of
grant, have a ten-year term and vest in equal increments of 33-1/3% on the
anniversary dates of the dates of grant. As of September 30, 1999 and June 30,
1999, options to purchase an aggregate of 1,437,497 and 1,440,796 shares of
common stock, respectively, were outstanding under the 1996 Plan, and an
additional 1,858,561 and 807,611 shares of common stock, respectively, were
reserved for future option grants.

During the year ended June 30, 1999, the Company restated the exercise price of
stock options previously granted to employees, directors and some consultants to
the Company. Options to purchase a total of 892,456 shares of the Company's
common stock were repriced from a weighted average of $3.88 per share to $0.375
per share, representing the fair market value of the Company's common stock as
of the date of the repricing. In accordance with APB 25, no expense was recorded
as a result of this repricing. The Financial Accounting Standards Board is
currently deliberating the accounting for stock option repricings, and is
expected to issue new guidance for such transactions. If new guidance is issued,
it may require the Company to record additional expense related to the repricing
in prospective financial statements.

As of September 30, 1999 and June 30, 1999, options to purchase an aggregate of
791,117 and 797,417 shares of common stock, respectively, were exercisable under
the Company's stock option plans. During the years ended June 30, 1999 and 1998
and the period from inception (February 10, 1987) through June 30, 1999, options
to

                                      F-15
<PAGE>

purchase 0, 0, and 261,289 shares of common stock, respectively, were issued to
certain directors and officers of the Company with exercise prices below the
fair market value of the common stock on the dates of grant. The aggregate
difference between the fair market value on the date of grant and the exercise
price of the options granted has been recorded as compensation expense over the
vesting period of the options. Stock option compensation expense related to
these transactions, aggregating $0, $0, $555,809, $0, $0 and $555,809 for the
three-month periods ended September 30, 1999 and 1998, and the period from
inception (February 10, 1987) through September 30, 1999, the years ended June
30, 1999 and 1998 and the period from inception (February 10, 1987) through June
30, 1999, respectively, has been recorded in the accompanying statements of
operations.

Stock option transactions under the Company's stock option plans for each of the
two years in the period ended June 30, 1999 are summarized below:

Pro-Forma Information -- The Company has elected to continue accounting for its
employee stock options in accordance with Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees" ("APB 25"). Under APB 25,
because the exercise price of the Company's employee stock options is equal to
the market price of the underlying stock on the date of grant, no compensation
expense is recognized.

Pro forma information regarding net loss and net loss per share is required by
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"), and has been determined as if the Company had
accounted for its employee stock plans under the fair value method. The fair
value was estimated at the date of grant using the Black-Scholes option pricing
model and the following assumptions for the years ended June 30, 1999 and 1998,
respectively: weighted average risk-free interest rates of 5.5% and 5.4%;
dividend yields of 0%; volatility factors of the expected market price of the
Company's common stock of 186% and 90%; and a weighted average life of 3.0 years
and 3.3 years. The estimated weighted average fair value of options granted
during the years ended June 30, 1999 and 1998 was $0.40 and $1.48, respectively.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized as expense over the vesting period of the options, resulting in the
following pro forma information for the years ended June 30, 1999 and 1998:

Note 5 -- Research and License Agreement with NV Organon

In January 1999, the Company entered into a research collaboration and exclusive
worldwide license agreement with NV Organon, a pharmaceutical business unit of
Akzo Nobel (The Netherlands). The agreement will enable Organon to develop and
commercialize the Company's proprietary Ampakine technology for the treatment of
schizophrenia and, upon Organon's election, for the treatment of depression.

In connection with the agreement with Organon, during the year ended June 30,
1999, the Company received an up-front payment of $2,000,000 and research
support payments of $1,150,000. In July 1999, the Company received further
research support of $762,500. The agreement includes research support payments
of up to $3,000,000 per year for two years (subject to Cortex providing agreed-
upon levels of research), milestone payments, plus royalty payments on worldwide
sales.

Note 6 -- Note Payable to Alkermes, Inc.

In January 1992, the Company entered into an agreement with Alkermes, Inc.
("Alkermes") for the development, clinical testing and commercialization of the
Company's calpain inhibitor products (the "Alkermes Agreement"). In connection
with the Alkermes Agreement, the Company granted Alkermes an exclusive worldwide
license to commercialize calpain inhibitor products for the prevention and
treatment of acute and chronic neurodegenerative diseases and disorders of the
central and peripheral nervous systems. The Company received an aggregate of
$3,600,000 in research payments under the Alkermes Agreement during the fiscal
years ended June 30, 1992 and 1993.

                                      F-17
<PAGE>

In November 1993, Alkermes filed an action alleging that the Company had
breached the Alkermes Agreement by developing calpain inhibitors for cerebral
vasospasm. In October 1995, the Company and Alkermes agreed to a settlement of
the dispute. Alkermes agreed to dismiss its action against the Company and to
relinquish all rights previously granted them by the Company, as well as rights
to related technologies developed by Alkermes. In connection with the
settlement, the Company issued to Alkermes a $1,000,000 three-year promissory
note accruing interest semi-annually at the federal funds rate. The Company also
committed to pay Alkermes a graduated royalty on calpain inhibitor development
proceeds, as defined and subject to certain limitations.

In February 1998, the terms of the note were restructured to include a principal
payment of $200,000 upon signing of the new agreement. The balance of the note
and accrued interest was payable in October 1999 or upon the consummation of a
corporate partnership between Cortex and a larger pharmaceutical company,
whichever was earlier. In connection with the restructuring agreement, the
Company issued to Alkermes a five-year warrant to purchase 75,000 shares of
common stock at an exercise price of $1.55 per share, representing the average
of the high and low sale prices of Cortex common stock as of the date of the
restructuring. With the signing of the license agreement with NV Organon (Note
5), the note and accrued interest became due and payable.

In July 1999, Alkermes agreed to restructure the terms of the note to include a
principal and interest payment of $250,000 and monthly payments of $50,000 from
August 1999 through January 2000. The balance of the note and accrued interest
are due and payable on or before February 28, 2000. Interest on the unpaid
balance accrues at a 1% to 3% premium to the prime lending rate, based upon the
date of payment. In connection with this restructuring agreement, the Company
agreed to issue to Alkermes a five-year warrant to purchase 100,000 shares of
common stock at an exercise price derived from the fair market value of the
Company's common stock. In accordance with the restructuring agreement, because
the balance of principal and accrued interest was not paid by December 31, 1999,
Cortex has agreed to issue to Alkermes another five-year warrant to purchase
50,000 shares of common stock at a price per share of $0.76. This exercise
price is derived from the average of the closing sale prices reported for the
Company's common stock for the 30 trading days preceding December 31, 1999.

If the Company needs to extend the due date of the note, it has agreed to issue
to Alkermes another five-year warrant to purchase 50,000 shares of Cortex common
stock.  The exercise price for this warrant will be derived from the fair market
value of the stock as of February 28, 2000.  If the due date is extended, the
Company agrees to continue to pay Alkermes $50,000 per month, with the balance
of the note and accrued interest due May 31, 2000.

Note 7 -- Commitments

The Company leases its offices and research laboratories under an operating
lease that expires May 31, 2004. Rent expense under this lease for the three-
month periods ended September 30, 1999 and 1998, the period from inception
(February 10, 1987) through September 30, 1999, the years ended June 30, 1999
and 1998 and the period from inception (February 10, 1987) through June 30, 1999
was $58,000, $55,000, $2,191,000, $260,000, $234,000 and $2,133,000,
respectively. Commitments under the lease for the years ending June 30, 2000,
2001, 2002, 2003 and 2004 are $255,000, $310,000, $353,000, $368,000 and
$356,000, respectively.

As of June 30, 1999, the Company was obligated to an executive officer under an
employment agreement expiring in May 2000. The agreement involves annual salary
payments aggregating $220,000 and provides for bonuses under certain
circumstances. Additionally, in the event that the Company commercializes a
compound developed by or under the supervision of one of its senior scientific
employees, the Company may be obligated to pay the employee a royalty based on
net sales, as defined and subject to adjustment, of products containing the
compound. As of June 30, 1999, the Company was committed under scientific
consulting and external research agreements to annual payments aggregating
approximately $672,000.

The Company has entered agreements with an academic institution that provide the
Company exclusive rights to certain of the technologies that the Company is
developing. Under the terms of the agreements, the Company is committed to
royalty payments. These payments include minimum annual royalties of $90,000 for
the year ending June 30, 2000 and for each year thereafter for the remaining
life of the patents covering the subject technologies. The agreements also
commit the Company to pay up to an additional $875,000 upon achieving certain
clinical testing and regulatory approval milestones, as well as a portion of
certain remuneration received by the Company in connection with sublicensing
agreements that the Company may enter into.

Note 8 -- Related Party Transactions

During the years ended June 30, 1999 and 1998, and the period from inception
(February 10, 1987) through June 30, 1999, the Company paid or accrued
scientific and other consulting fees to stockholders aggregating $78,417,
$88,000 and $1,184,974, respectively. Under certain circumstances, the Company
is obligated to make royalty payments to certain of its scientific consultants,
some of whom are stockholders, and to one employee, upon successful
commercialization of certain of its products by the Company or its licensees.

In connection with its services as placement agent in the 1993 private placement
of 2,750,000 shares of common stock, Vector was paid a fee of $1,096,800 and was
issued a five-year non-redeemable warrant to purchase 274,200 shares of the
Company's common stock at $9.375 per share. In connection with Vector's
assistance in reaching the settlement with Alkermes (Note 6), this warrant was
canceled and reissued as a new warrant to purchase 363,113 shares of the
Company's common stock at $3.47 per share, as adjusted and subject to further
adjustment, at any time through January 15, 2000. The value of this new warrant
was computed utilizing the Black-Scholes option pricing model, and was recorded
with the expense of the settlement with Alkermes in the accompanying statement
of operations. This warrant expired unexercised.

As consideration for its agreement to provide financial advisory services, as
amended and extended in November 1994, Vector was paid a retainer of $50,000 and
was issued a six-year non-redeemable warrant to purchase 57,193 shares of the
Company's common stock at $3.06 per share, subject to adjustment under certain
circumstances. Warrants to purchase 8,169 shares of the Company's common stock
vested immediately, and warrants to purchase 24,512 shares of the Company's
common stock vest upon the consummation of each strategic alliance when and as
secured by Vector.

Note 9 -- Income Taxes

The Company uses the liability method of accounting for income taxes as set
forth in Statement of Financial Accounting Standards No. 109, "Accounting for
Income Taxes." Under the liability method, deferred taxes are determined based
on differences between the financial statement and tax bases of assets and
liabilities using enacted tax rates. As of June 30, 1999, the Company had
federal and California tax net operating loss carryforwards of approximately
$34,459,000 and $4,131,000, respectively. The difference between the federal and
California tax loss carryforwards is primarily attributable to the
capitalization of research and development expenses for California franchise tax
purposes and the fifty percent limitation on California loss carryforwards. The
California tax loss carryforwards will continue to expire in 1999 (approximately
$701,000 expired in 1998), while the federal carryforwards begin expiring in
2004. The Company also has federal and California research and development tax
credit carryforwards totaling $1,154,000 and $440,000, respectively, which will
begin to expire in 2004.

Utilization of the net operating loss and tax credit carryforwards from the tax
years ended on or before June 30, 1992 is subject to an annual limitation of
approximately $1,500,000, due to ownership change limitations provided by the
Internal Revenue Code of 1986 and similar state provisions. If there should be
future changes of ownership, these annual limitations for utilization of net
operating loss and tax credit carryforwards may become more restrictive.
Pursuant to Internal Revenue Code Sections 382 and 383, use of the Company's net
operating loss carryforwards may be limited if a cumulative change in ownership
of more than 50% occurs within any three-year period since the last ownership
change.

Significant components of the Company's deferred tax assets as of June 30, 1999
and June 30, 1998 are shown below. The valuation allowance related to deferred
tax assets is $15,629,000 and $15,413,000 for the years ended June 30, 1999 and
1998, respectively. The increase in the valuation allowance for the year ended
June 30, 1999 of $216,000 is primarily due to additional reserves required for
new deferred tax assets.
