                         CORTEX PHARMACEUTICALS, INC.


                       3,801,918 Shares of Common Stock
                         (Par Value $0.001 Per Share)

   
This Prospectus relates to the sale of up to 3,801,918 shares (the "Shares") 
of the common stock, par value $0.001 per share (the "Common Stock"), of 
Cortex Pharmaceuticals, Inc. ("Cortex" or the "Company") by certain 
stockholders of the Company (the "Selling Stockholders"). The Shares include 
440,573 shares of Common Stock issuable upon exercise of currently 
outstanding warrants (the "Warrant Shares") and up to 3,361,345 shares of 
Common Stock that may be issuable upon conversion of Series D Preferred Stock 
(the "Conversion Shares").  The Conversion Shares include an allowance for 
shares of Common Stock that may be issuable upon conversion of Series D 
Preferred Stock in the event of a decline in the market price of the Common 
Stock (see "Description of Securities -- Preferred Stock," "Selling 
Stockholders -- Footnote 1," and "Risk Factors -- Shares Eligible for Future 
Sale; Dilution; Control").  The Selling Stockholders may sell the Shares from 
time to time in transactions in the over-the-counter market, 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 prevailing at 
the time of the sale, at prices related to such 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 or commissions from the Selling Stockholders or from the purchasers
of the Shares for whom the broker-dealers may act as an agent or to whom they 
may sell as a principal, or both. The Selling Stockholders and such 
brokers-dealers may be deemed to be "underwriters" within the meaning of the 
Securities Act of 1933, in connection with such sales. See "Selling 
Stockholders" and "Plan of Distribution." 
    
The Company will not receive any part of the proceeds from the sale of the 
Shares. The Company has agreed to bear all of the expenses in connection with 
the registration and sale of the Shares (other than underwriting discounts 
and selling commissions and the fees and expenses of counsel or other 
advisors to the Selling Stockholders).  
   
The Common Stock of the Company trades on the Nasdaq Small-Cap Market under 
the symbol CORX. On December 12, 1996, the high and low sale prices of a share 
of Common Stock of the Company, as reported by Nasdaq, were $4.75 and 
$4.3125, respectively. See "Price Range of Common Stock."

                              PROSPECTUS SUMMARY

THE FOLLOWING IS A SUMMARY QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED 
INFORMATION AND FINANCIAL STATEMENTS (INCLUDING THE NOTES THERETO) APPEARING 
ELSEWHERE IN THIS PROSPECTUS. ALL SHARE AND PER SHARE DATA HAVE BEEN RESTATED 
TO REFLECT A ONE-FOR-FIVE REVERSE STOCK SPLIT THAT WAS EFFECTED JANUARY 11, 
1995. AN INVESTMENT IN THE SHARES OFFERED HEREBY INVOLVES A HIGH DEGREE OF 
RISK. SEE "RISK FACTORS."

This Prospectus contains certain forward-looking statements that are based on 
current expectations that involve a number of risks and uncertainties. These 
forward-looking statements are based on assumptions that the Company will be 
able to obtain sufficient financing to continue operations, that the 
Company's technology will continue to be developed and will not be replaced 
by new technology, that the Company will retain key technical and management 
personnel, and that there will be no material adverse change in the Company's 
operations or business. Assumptions relating to the foregoing involve 
judgments with respect to, among other things, future technology, economic, 
competitive and market 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 can be no 
assurance that the results contemplated in the forward-looking statements 
will be realized. In addition, the business and operations of the Company are 
subject to substantial risks which increase the uncertainty inherent in such 
forward-looking statements. 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 of the Company or 
any other person that the objectives or plans of the Company will be 
achieved. The following summary is qualified in its entirety by the more 
detailed information and the Financial Statements and the Notes thereto 
appearing elsewhere in this Prospectus.

THE COMPANY

Cortex Pharmaceuticals, Inc. ("Cortex" or the "Company") is a development 
stage enterprise 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. 
The primary product development effort at Cortex is centered on the AMPA 
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-TM-, to 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. In October 1994, the Company initiated human 
safety studies with CX516 (AMPALEX-TM-) for the potential treatment of 
deficits of memory and cognition due to Alzheimer's disease. To date, these 
studies have involved healthy young adult and healthy elderly volunteers. The 
Company plans to initiate a small study in Alzheimer's disease patients in 
fiscal 1997. Cortex is also investigating the potential utility of its 
AMPAKINEs in the treatment of schizophrenia. In fiscal 1996, the Company 
maintained a strong focus on the AMPA receptor program but, with the 
reacquisition of rights to calpain inhibitor compounds from Alkermes in 
October 1995, reinstituted a research effort in this area.

Cortex believes that its competitive advantage is the quality of its science 
and technology, and that it can compete effectively with larger, more 
established, better capitalized entities in the area of discovery of 
innovative pharmaceuticals. The Company does not, however, have the resources 
or expertise for later-stage clinical development, manufacturing and 
worldwide marketing of major pharmaceuticals. The Company's commercial 
development plans therefore involve partnering with larger pharmaceutical 
companies for Phase II and later clinical testing, manufacturing and global 
marketing of its proposed products, while attempting to retain the right to 
eventually co-promote in the United States. If the Company is successful in 
the pursuit of this strategy, it is intended that it will be in a position to 
contain its costs over the next few years, to maintain its focus on the 
research and early development of innovative pharmaceuticals, and to 
eventually participate more fully in the commercial development of its 
proposed products in the United States. Cortex is actively seeking 
collaborative or licensing arrangements with larger pharmaceutical companies 
that will permit its product candidates to be advanced into the later stages 
of clinical development and that will provide access to the extensive 
clinical trials management, manufacturing and marketing expertise of such 
companies. There can be no assurance, however, that the Company will secure 
such arrangements on favorable terms, or at all, or that its products will be 
successfully developed and approved for marketing by government regulatory 
agencies, or accepted by patients, health care providers and insurers.

                                RISK FACTORS
                                       
AN INVESTMENT IN THE COMMON STOCK OFFERED HEREBY IS SPECULATIVE IN NATURE, 
INVOLVES A HIGH DEGREE OF RISK, AND SHOULD NOT BE MADE BY ANY INVESTOR WHO 
CANNOT AFFORD THE LOSS OF HIS ENTIRE INVESTMENT. EACH PROSPECTIVE INVESTOR 
SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS AND SPECULATIVE FACTORS, AS 
WELL AS OTHERS DESCRIBED ELSEWHERE IN THIS PROSPECTUS, ASSOCIATED WITH THIS 
OFFERING BEFORE MAKING AN INVESTMENT.

NEED FOR ADDITIONAL FUNDS. Cortex anticipates that its existing capital 
resources (including approximately $950,000 in net proceeds received in 
October 1996 from the first tranche of a three-tranche private placement of 
Series D Preferred Stock) will enable it to maintain its current and planned 
operations through June 1997. The second and third tranches of the private 
placement, if and when received, are expected to provide an additional 
$3,000,000 of total gross proceeds, which amount is expected to fund 
operations into calendar 1998. The Company will require additional funds to 
continue its operations beyond the first calendar quarter of 1998. There can 
be no assurance that the Company will be able to obtain the additional needed 
funds on reasonable terms, or at all. See "Management's Discussion and 
Analysis of Financial Condition and Results of Operations."

DEVELOPMENT STAGE COMPANY; HISTORY OF LOSSES. Cortex is a development stage 
enterprise. From inception on February 10, 1987 through September 30, 1996, 
the Company has generated only modest operating revenues and has incurred net 
losses aggregating $26,411,152. As of September 30, 1996, the Company had an 
accumulated deficit of $26,550,826. The Company will require substantial 
additional funds to advance its research and development programs, 
particularly should the Company decide to independently conduct later-stage 
clinical testing and apply for regulatory approval of any of its proposed 
products. There can be no assurance that such additional financing will be 
available on acceptable terms, or at all. If additional funds are raised by 
issuing equity securities, further dilution to existing stockholders may 
result. If the Company is unable to obtain additional funds when and as 
needed, the Company may be required to significantly curtail one or more of 
its product development programs. See "Management's Discussion and Analysis 
of Financial Condition and Results of Operations" and "Business."
   
TECHNOLOGICAL UNCERTAINTY; EARLY STAGE OF PRODUCT DEVELOPMENT; NO ASSURANCE 
OF REGULATORY APPROVALS. 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 are 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 a superior or equivalent product. 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 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. To date, the Company has conducted clinical trials in Europe only.  The 
Company has not yet filed an IND with the Food and Drug Administration, 
which is required prior to the commencement of clinical testing in the United 
States.  See "Business."
    
DEPENDENCE ON THIRD PARTIES FOR CLINICAL TESTING, MANUFACTURING AND 
MARKETING. The Company does not have the resources, and does not presently 
intend, to conduct later-stage human clinical trials or to manufacture any of 
its proposed products. The Company is therefore seeking larger pharmaceutical 
company partners to conduct such activities for most or all of its proposed 
products. In connection with its efforts to secure corporate partners, the 
Company will seek to retain certain co-promotional rights to its proposed 
products, so that it may promote such products to selected medical 
specialists while its corporate partner promotes to the general medical 
market. There can be no assurance that the Company will be able to enter into 
any such partnering arrangements on this or any other basis. In addition, 
there can be no assurance that either the Company or its prospective 
corporate partners can successfully introduce its proposed products, that 
they will achieve acceptance by patients, health care providers and insurance 
companies, or that they can be manufactured and marketed at prices that would 
permit the Company to operate profitably. See "Business."

DEPENDENCE ON RELATIONSHIPS WITH KEY CONSULTANTS AND THE UNIVERSITY OF 
CALIFORNIA, IRVINE.  The Company is highly dependent upon its relationships 
with a number of key academic consultants, particularly Drs. Carl W. Cotman 
and Gary S. Lynch of the University of California, Irvine ("UCI"). Drs. 
Cotman and Lynch play an important role in guiding the

                                       5

<PAGE>

internal research of the Company. In addition, Cortex sponsors research in 
the laboratories of Dr. Lynch at UCI that is an important component of the 
Company's product development and corporate partnering profile. The sponsored 
research is highly technically demanding and involves the use of expensive 
equipment, much of it custom-built, that is the property of UCI. Were 
Cortex's relationships with Dr. Lynch or UCI to be disrupted, it is likely 
that the Company's AMPA receptor research program would be adversely 
affected, and there is no assurance that the Company would be able to conduct 
the sponsored research internally at reasonable cost, or at all. The 
Company's agreements with its consultants, including those with Drs. Cotman 
and Lynch, are generally terminable by the consultant on short notice. The 
loss of services of certain of these individuals, and particularly Dr. Lynch, 
could have a material adverse effect on the Company. See "Management."

LIMITED PROPRIETARY RIGHTS; LACK OF PATENT PROTECTION.  Since its initial 
public offering in July 1989, the Company has negotiated technology rights 
agreements giving it exclusive rights to its proposed cognition enhancement 
products and calpain inhibitor products under patents or patent applications 
owned wholly by other parties or by other parties as co-owners with the 
Company. The Company also holds options or other rights to obtain exclusive 
licenses under patent applications relating to certain of its potential 
products. Certain of the Company's licenses and other agreements are 
terminable if the Company does not make certain minimum annual payments, meet 
certain milestones or diligently seek to commercialize the underlying 
technology. In addition, the Company's related collaborative and consulting 
agreements are generally terminable upon 30 to 60 days' written notice.

There can be no assurance that current or future patent applications in which 
Cortex has an interest, either as sole owner or as a current or prospective 
licensee, will result in patents being issued. There can also be no assurance 
that patents issuing in the future in connection with current or future 
patent applications will afford effective protection against competitors with 
similar technology, or that any patents issued or licensed to Cortex will not 
be infringed upon or designed around by others.

If Cortex is unable to obtain protection of its proprietary rights in its 
products or processes prior to or after obtaining regulatory clearances, 
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.

In some cases, Cortex may rely on trade secrets to protect its innovations. 
There can be no assurance that secrecy obligations will be honored or that 
others will not independently develop similar or superior technologies. To 
the extent that consultants, key employees or other third parties apply 
technological information independently developed by them or by others to the 
Company's projects, disputes may arise as to the proprietary rights to such 
information that may not be resolved in favor of the Company. See 
"Business--Patents and Proprietary Rights."
   
SHARES ELIGIBLE FOR FUTURE SALE; DILUTION; CONTROL.  If all outstanding 
warrants and options are exercised prior to their expiration, approximately 
1,350,000 additional shares of Common Stock could become freely tradeable 
without restriction under the Securities Act. An aggregate of 29,384 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 tradeable. As of December 12, 1996, 339,847 shares of Common Stock are 
issuable upon conversion of 100 shares of Series D Preferred Stock issued in 
the first tranche at an effective conversion price of $2.9425 per share of 
Common Stock.  However, the exact number of shares issuable depends on the 
date of conversion and the then current market price of the Common Stock.  
See "Description of Securities -- Preferred Stock."  On December 12, 1996, 
the last sale price of the Common Stock as reported by Nasdaq was $4.375 per 
share.  If the market price of the Common Stock is below $3.59 per share at 
the time(s) of conversion, the effective conversion prices(s) of the Series D 
Preferred Stock issued in the first tranche will be lower, and potentially 
much lower, than $2.9425 per share, resulting in the issuance of more Common 
Stock upon conversion of the Series D Preferred Stock.  In the event of a 
precipitous decline in the market price of the Common Stock, this may lead to 
very substantial dilution to current holders of the Common Stock.  Further, 
since all of the shares of Series D Preferred Stock are being acquired by a 
single investor, under such circumstances the investor may be in a position 
to exert influence and control over the affairs of the Company.The Series D 
Preferred Stock issued or issuable pursuant to the October 1996 private 
placement (see Note 10 of Notes to Financial Statements) is also convertible 
into shares of Common Stock at a conversion price indexed to the market price 
of the Common Stock at the time of conversion. An additional 300 shares of 
Series D Preferred Stock are planned for issuance upon closing of the second 
and third tranches at effective conversion prices that cannot presently be 
determined, but that may be lower than the effective conversion price for the 
currently outstanding Series D Preferred Stock. The Series D Preferred Stock 
to be issued in the second and third tranches of the October 1996 private 
placement also presents the risks discussed immediately above pertaining to 
dilution and control.  On issuance upon conversion of Series D Preferred 
Stock, all of such shares of Common Stock may be freely tradeable. Sales of 
substantial amounts of Common Stock in the public market could adversely 
affect the prevailing market price of the Common Stock and, dependent upon 
the then current market price of the Common Stock, increase the risks 
associated with conversion of Series D Preferred Stock that are discussed 
above.  See "Selling Stockholders -- Footnote 1," and "Description of 
Securities -- Preferred Stock."

COMPETITION.  The Company's business is characterized by intensive research 
efforts. Many companies, research institutes and universities are working in 
a number of pharmaceutical or biotechnology disciplines to develop 
therapeutic products similar to those under investigation by the Company. 
Most of these companies, research institutes and universities have 
substantially greater financial, technical, manufacturing, marketing, 
distribution and/or other resources than Cortex. In addition, many of such 
companies have experience in undertaking human clinical trials of new or 
improved therapeutic products and obtaining FDA and other regulatory 
clearances of products for use in human health care. The Company has no 
experience in conducting and managing clinical testing or in preparing 
applications necessary to gain regulatory clearances. Accordingly, other 
companies may succeed in developing products that are safer or more effective 
than those proposed to be developed by the Company and in obtaining FDA 
clearances for such products more rapidly than the Company. Further, it is 
expected that competition in this field will continue to intensify over the 
next few years. See "Business--Competition."

DEPENDENCE UPON KEY PERSONNEL.  Cortex is highly dependent upon key 
management and technical personnel. Competition for qualified employees among 
pharmaceutical and biotechnology companies is intense, and the loss of any of 
such persons, or an inability to attract, retain and motivate the additional 
highly-skilled employees and consultants required for the Company's 
activities, could materially adversely affect its business and prospects. 
There can be no assurance that Cortex will be able to retain its existing 
personnel or attract additional qualified employees when they are needed. See 
"Business" and "Management."

GOVERNMENT REGULATION.  Therapeutic products such as those proposed to be 
developed by Cortex are subject to an extensive and lengthy regulatory review 
and approval process by the FDA and comparable agencies in other countries. 
Prior to commercialization, the Company's products will require governmental 
approvals that have not yet been obtained and that are not expected to be 
obtained for several years, if at all. The regulatory process, which includes 
pre-clinical, clinical and post-clinical testing of the Company's products to 
establish their safety and efficacy, will take many years and require the 
expenditure of substantial resources. There can also be no assurance that, 
even after such time and expenditures, regulatory clearances will be obtained 
for any of the Company's products. 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. In addition, the 
current administration in the U.S. is proposing changes in federal regulation 
and reimbursement policies intended to facilitate the delivery of 
cost-effective health care. The implementation of such proposed changes may 
affect the regulation and availability of, and the pricing and reimbursement 
for, health care products. The Company is unable to predict the effect, if 
any, that these proposed changes will have on the Company. See 
"Business--Government Regulation."

PRODUCT LIABILITY AND INSURANCE.  The clinical testing, manufacturing and 
marketing of the Company's products may expose the Company to product 
liability claims. Cortex maintains liability insurance with coverage limits 
of $5 million per occurrence and $5 million in the annual aggregate. Although 
the Company has never been subject to a product liability claim, there can be 
no assurance 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.

LIMITED PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE.  The Company's 
Common Stock has been publicly traded since July 1989. Although the Company 
currently has approximately 20 market makers, there can be no assurance that 
an active or established trading market for the Company's Common Stock will 
be maintained. The Company's Common Stock currently trades on the Nasdaq 
Small Cap Market. There can be no assurance that the Company's Common Stock 
will continue to be traded on the Nasdaq Small Cap Market.

There is significant volatility in the market price of securities of life 
sciences companies generally, and the trading price of the Company's Common 
Stock has been subject to wide fluctuations. See "Price Range of Common 
Stock." Various factors and events, including announcements by the Company or 
its competitors concerning technological innovations, new products, proposed 
governmental regulations or actions, developments or disputes relating to 
patents or proprietary rights and public concern over the safety of 
therapeutic products or other factors that affect the market generally, may 
have a significant impact on the Company's business and on the market price 
of the Company's securities.

DIVIDENDS.  The Company has not paid cash dividends on its Common Stock and 
does not anticipate doing so in the foreseeable future. The Company may not 
pay any dividends on its Common Stock until accrued and unpaid dividends on

                                       7

<PAGE>

the 9% Preferred Stock have been paid in full. As of September 30, 1996, 
accrued and unpaid dividends on the 9% Preferred Stock were $64,350. See 
"Dividend Policy."

ANTI-TAKEOVER PROVISIONS.  The Board of Directors has the authority, without 
further approval of the Company's stockholders, to issue up to 549,340 shares 
of Preferred Stock having such rights, preferences and privileges as the 
Board of Directors may determine. Any such issuance of additional shares 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. See "Description of Securities."

                               USE OF PROCEEDS
                                       
The proceeds from the sale of each Selling Stockholder's Shares will belong 
to the Selling Stockholders. The Company will not receive any of the proceeds 
from such sales of the Shares.

                          PRICE RANGE OF COMMON STOCK

The Common Stock (Nasdaq symbol: "CORX") began trading publicly in the 
over-the-counter market on July 18, 1989.  The following table presents 
quarterly information on the high and low sale prices of the Common Stock for 
the fiscal years ended June 30, 1996 and 1995, and thereafter, as reported by 
Nasdaq. These quotations reflect inter-dealer prices, without retail mark-up, 
mark-down or commission, may not represent actual transactions and have been 
adjusted for a one-for-five reverse stock split that became effective January 
11, 1995.

As of November 30, 1996, there were 590 stockholders of record of the 
Company's Common Stock, and approximately 7,400 beneficial owners. The last

Nasdaq, was $4-3/8.
    
                                DIVIDEND POLICY
                                       
The Company has never paid cash dividends on the 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 semiannual installments 
on June 15 and December 15 of each year, which dividends must be paid in full 
before any dividends can be paid on the Common Stock. As of September 30, 
1996, accrued and unpaid dividends on the 9% Preferred Stock were $64,350. 
The payment of future dividends, if any, will be determined by the Board of 
Directors in light of

                                       8

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.

(2) On October 15, 1996, the Company issued 100 shares of newly created Series
    D Preferred Stock ("Series D Preferred") at a price of $10,000 per share in
    the first tranche of a three-tranche Regulation D private placement. The
    Series D Preferred Stock is convertible at an effective per share
    conversion price that is the lower of (i) 110% of the average closing bid
    price for the five trading days immediately preceding the closing date
    ($2.9425 for the first tranche) or (ii) that price that is 18% below the
    average closing bid price for the five trading days immediately preceding
    the conversion date, in each case subject to adjustment at the rate of six
    percent per annum based on the length of the period from issuance of the
    Series D Preferred until its conversion. The Company intends to sell a
    second tranche of 150 shares of Series D Preferred (for gross proceeds of
    $1,500,000) 15 days following the effectiveness of a registration statement
    covering the resale of

                                       9

    shares of Common Stock issuable upon conversion of the Series D Preferred, 
    and a third tranche of 150 shares 60 days following the closing of the 
    second tranche. The closing of the second and third tranches is subject 
    to certain conditions, which conditions are outside the control of the 
    investor, including but not limited to minimums for price and trading 
    volume of the Company's common stock. See "Description of Securities" and 
    Note 10 of Notes to Financial Statements.

                      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 (INCLUDING THE NOTES THERETO) APPEARING ELSEWHERE HEREIN.

RESULTS OF OPERATIONS

From inception (February 10, 1987) through September 30, 1996, the Company's 
revenue has consisted of (i) $3,600,000 of license fees and research and 
development funding from January 1992 through June 1993 under the Company's 
agreement with Alkermes, Inc. ("Alkermes," see Note 6 of Notes to Financial 
Statements), (ii) net interest income aggregating $1,368,000, and (iii) 
$95,000 of grant revenue.

From inception (February 10, 1987) through September 30, 1996, the Company 
has sustained losses aggregating $26,411,152. Continuing losses are 
anticipated over the next several years, as the Company's ongoing operating 
expenses for preclinical research and early clinical development will only be 
offset, if at all, by licensing revenues under planned strategic alliances 
with larger pharmaceutical companies that the Company is seeking for the 
later stages of clinical development, manufacturing and marketing of its 
products. The nature and timing of payments to Cortex under these planned 
strategic alliances, if and as entered into, is likely to significantly 
affect the Company's operations, and to produce substantial period-to-period 
fluctuation in reported financial results. Over the longer term, the Company 
will be dependent upon successful commercial development of its products by 
its prospective partners to attain profitable operations from product 
royalties or other revenues based on product sales.

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, 1996 AND 1995

For the year ended June 30, 1996, the Company's net loss of $4,158,000 
compares with a net loss of $6,836,000 for the prior year. The net loss for 
the prior year includes $1,228,000 of expenses related to the settlement of 
the dispute with Alkermes (see Note 6 of Notes to Financial Statements) and 
higher research and development expenditures in connection with the 
initiation of human clinical studies.

General and administrative expenses of $1,644,000 for the year ended June 30, 
1996 were essentially unchanged from the prior year. The very slight decrease 
was the result of lower outlays for consulting expenses, partially offset by 
increased recruiting fees incurred with the hiring of the new Chief Executive 
Officer.

Research and development expenses decreased to $2,678,000, or by 35%, in the 
year ended June 30, 1996. Most of the decrease from the prior year was 
attributable to clinical testing of AMPALEX (for the potential treatment of 
memory deficits due to Alzheimer's disease) in the prior year, as well as 
lower salary and related expenses due to a temporary reduction in scientific 
personnel that was effected as of June 30, 1995. Lower outlays for scientific 
consulting contributed most of the remaining decrease.

THREE-MONTH PERIODS ENDED SEPTEMBER 30, 1996 AND 1995

The net loss for the three-month period ended September 30, 1996 of 
$1,192,000 compares with a net loss of $955,000 for the corresponding prior 
year period. The increased operating expenses were primarily attributable to 
scientific and administrative personnel additions, along with increased 
levels of external research.

General and administrative expenses increased from $323,000 to $432,000 or by 
$109,000 (34%) during the three-month period ended September 30, 1996 
compared to the corresponding prior year period. The bulk of the increase was 
from the relocation of the new Chief Executive Officer, the hiring of a 
business development executive and increased travel expenses in connection 
with corporate partnering activities.

                                       13

<PAGE>

Research and development expenses increased from $665,000 to $794,000, or by 
$129,000 (19%), during the three-month period ended September 30, 1996 
compared to the corresponding prior year period. The increase was principally 
due to higher outlays for sponsored research, additions to the complement of 
scientific employees and a resultant increase in spending for laboratory 
supplies, partially offset by lower clinical trials expenses.

PLAN OF OPERATIONS; LIQUIDITY AND CAPITAL RESOURCES

CORTEX has funded its organizational and research and development activities 
primarily from the issuance of equity securities, with net proceeds from 
inception (February 10, 1987) through September 30, 1996 aggregating $28 
million. An additional $3.6 million in research and license payments was 
received from Alkermes between January 1992 and June 1993 in connection with 
the development and license agreement with that firm (see Note 6 of Notes to 
Financial Statements). Interest income from inception through September 30, 
1996, which approximates funds received, was $1.4 million.

As of September 30, 1996, the Company had cash, cash equivalents and 
short-term investments totaling $2.9 million and working capital of $2.7 
million. In comparison, as of September 30, 1995, the Company had cash, cash 
equivalents and short-term investments of $3.1 million and working capital of 
$2.6 million. The decreases resulted from amounts required to fund operating 
losses and to purchase capital equipment, partially offset by approximately 
$3.6 million received from a private placement of Series C Preferred Stock in 
December 1995. From inception (February 10, 1987) through September 30, 1996, 
net expenditures for furniture, equipment and leasehold improvements 
aggregated $1.9 million.

As of September 30, 1996, Cortex had outstanding 110,000 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 15, 1990. Accrued and unpaid dividends as of September 30, 
1996 were $64,350.

The Company leases approximately 30,000 square feet of research laboratory, 
office and expansion space under an operating lease that expires May 31, 
1999, with an additional five-year option at 95% of the then fair market 
rental rate. The commitments under the lease agreement for the years ending 
June 30, 1997, 1998 and 1999 are $229,000, $234,000 and $220,000, 
respectively.

In connection with the settlement in October 1995 of the license dispute with 
Alkermes (see Note 6 of Notes to Financial Statements), the Company issued to 
Alkermes a $1,000,000 three-year promissory note accruing interest 
semi-annually at the then federal funds rate. The Company also agreed to pay 
Alkermes a graduated royalty on calpain inhibitor development proceeds, as 
defined and subject to certain limitations.

Over the next twelve months, the Company plans to conduct additional 
preclinical and Phase I/II clinical studies on its AMPAKINE compounds. This 
planned research involves a twelve-month expenditure of approximately $4.2 
million. This amount includes approximately $966,000 of funding for sponsored 
research in academic laboratories, to which the Company is or will be 
committed under various license agreements and sponsored research agreements. 
Significant investments in plant or equipment or substantial changes to 
staffing levels are not contemplated under current spending plans for the 
next twelve months. As of September 30, 1996, Cortex had 19 full-time 
employees and one part-time employee.

On October 15, 1996, Cortex completed the first tranche of a Regulation D 
private placement of Series D Preferred Stock and in connection therewith 
received gross proceeds of $1,000,000. The Company is to receive an 
additional $3,000,000 in two additional tranches, subject to certain 
conditions. See Note 10 of Notes to Financial Statements.

Cortex anticipates that its existing cash, cash equivalents and short-term 
investments, combined the proceeds from the first tranche of the October 1996 
financing and a modest amount of anticipated interest income, will be 
sufficient to satisfy its capital requirements through June 1997 under 
current spending plans. The successful closing of the second and third 
tranches of the October 1996 financing is expected to extend this through the 
first calendar quarter of 1998.

Over the longer term, the Company will require substantial additional funds 
to maintain and expand its research and development activities and to 
ultimately commercialize, with or without the assistance of corporate 
partners, any of its

                                       14

proposed products. The Company is seeking collaborative or other arrangements 
with larger pharmaceutical companies, 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 the Company is developing. However, the competition for such 
arrangements with major pharmaceutical companies is intense, with a large 
number of biopharmaceutical companies attempting to satisfy their funding 
requirements through such arrangements. Accordingly, although the Company is 
presently engaged in discussions with a number of suitable candidate 
companies, there can be 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- or long-term funding requirements. Additional 
equity or debt financings will be required, and there can be no assurance 
that funds will be available from such financings on favorable terms, or at 
all. If additional funds are raised by issuing equity securities, and 
dependent upon the nature and timing of such issuances, dilution to then 
existing stockholders is likely to result.

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. The primary product development effort at Cortex is 
centered on the AMPA 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-TM-, to 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. In October 1994, the 
Company initiated human safety studies with CX516 (AMPALEX-TM-) for the 
potential treatment of deficits of memory and cognition due to Alzheimer's 
disease. To date, these studies have involved healthy young adult and healthy 
elderly volunteers. The Company plans to initiate a small study in 
Alzheimer's disease patients in fiscal 1997. Cortex is also investigating the 
potential utility of its AMPAKINEs in the treatment of schizophrenia. In 
fiscal 1996, the Company maintained a strong focus on the AMPA receptor 
program but, with the reacquisition of rights to calpain inhibitor compounds 
from Alkermes in October 1995, reinstituted a research effort in this area. 
In the fiscal years ended June 30, 1996 and 1995, the Company's expenditures 
on research and development were $2,677,577 and $4,138,731, respectively, 
with the decrease attributable to a higher level of human clinical testing of 
AMPALEX in fiscal 1995.

Each of Cortex's programs addresses a large potential market. The Company's 
current commercial development plans involve partnering with larger 
pharmaceutical companies for Phase II and later clinical testing, 
manufacturing and global marketing of its proposed products, while attempting 
to retain the right to eventually co-promote in the United States. If the 
Company is successful in the pursuit of this strategy, it is intended that it 
will 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. Cortex continues to seek 
collaborative or licensing arrangements with larger pharmaceutical companies 
that will permit AMPALEX-TM- to be advanced into later stages of clinical 
development and provide access to the extensive clinical trials management, 
manufacturing and marketing expertise of such companies. There can be no 
assurance, however, that the Company will secure such arrangements on 
favorable terms, or at all, or that its products will be successfully 
developed and approved for marketing by government regulatory agencies.

AMPA RECEPTOR PROGRAM

In June 1993, Cortex licensed from the University of California a new class 
of compounds--the AMPAKINEs--that facilitate the functioning of the AMPA 
subtype of receptor for the neurotransmitter glutamate. These AMPAKINE 
compounds interact in a highly specific manner with the AMPA receptor in the 
brain, lowering the amount of neuronal stimulation required to generate a 
response. It is hoped that this selective signal amplification 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. Two prominent diseases that may 
benefit from AMPA receptor-directed therapeutics are Alzheimer's disease and 
schizophrenia, both of which represent large unmet medical needs.

DEFICITS OF MEMORY AND COGNITION -- ALZHEIMER'S DISEASE

Impairment of memory and cognition is becoming a very serious problem as the 
elderly proportion of the 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. According to a 1985 
survey of nursing homes conducted by the National Center for Health 
Statistics, over half of the individuals in nursing homes have some degree of 
cognitive impairment. Pharmaceuticals to alleviate deficits in memory and 
cognition could potentially enable many of the elderly to remain independent 
longer.

Memory is not located in a specific area of the brain, but rather becomes 
established in multiple areas of the brain that are involved with different 
types of sensory information. The prevailing scientific theory is that the 
brain deals with new information by constructing electrochemical and 
structural frameworks to put the information into some sort of context. Most 
of this processing, at least three-fourths of which is taken up with complex 
activities often referred to as "associations," appears to be handled in the 
cerebral cortex. The cerebral cortex is where the brain generates thoughts, 
language and plans, controls sensations and voluntary movements, evokes 
imagination, and stores certain types of permanent memory.

Substantial scientific evidence points to a long-lasting change--known as 
"long-term potentiation," or LTP--in synapses (junctions between neurons) as 
the basis of many types of memory. Long-term potentiation involves a series 
of chemical reactions that creates a more stable information transfer point 
between neurons. Experimental disruption of these chemical reactions in lower 
animals has been shown to cause a disruption of memory acquisition. In an 
important experiment with mice, for example, a single genetic change was made 
to prevent the production of a protein involved in long-term potentiation. 
When the mice were tested, they were unable to learn to swim out of a maze 
that required memory of spatial cues.

Although disease and physiological malfunctions are thought to be the 
fundamental cause of severe mental decline, age itself is a contributory 
factor. The human brain loses 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 usually designated as the AMPA receptor (which is 
involved in long-term potentiation). AMPA receptors and synapses decline in 
number with aging, making it more difficult for information to pass through 
and between areas of the cerebral cortex. A potential corrective approach to 
alleviate age-related cognitive deficits is therefore to develop novel 
compounds to enhance the activity of the AMPA receptors that are still 
present.

Alzheimer's disease is the best known destroyer of memory, already afflicting 
some four million Americans. With the aging of our population, unless a 
treatment is found the number of Americans with Alzheimer's disease is 
expected to double over the next two decades. According to the Alzheimer's 
Association, Alzheimer's disease is 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. 
Because the disease is so closely tied to aging, it has been estimated that 
delaying the onset of its symptoms by only five years would HALVE the number 
of people diagnosed with the disease.

Alzheimer's disease is a progressive, degenerative and uniformly fatal 
disease that slowly destroys the brain. The early symptoms are problems with 
memory of recent events and difficulty performing familiar tasks. As the 
disease progresses, other symptoms appear. These include confusion, 
personality change, behavioral change, impaired judgment, and difficulty 
finding words, finishing thoughts, or following directions. While the disease 
progresses at different rates in different individuals, eventually the 
victims are unable to care for themselves. Ultimately, they become less 
resistant to infections and other illnesses, which are often the actual cause 
of death.

It is in the early stages of Alzheimer's disease--the first few years--that 
Cortex believes AMPAKINEs may someday play a valuable role, enhancing the 
effectiveness of the brain cells that have not yet succumbed to the disease. 
This may 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 excitatory input from other brain cells 
to remain alive. As neurons die, other neurons begin to lose their excitatory 
inputs, hastening their own death. It may be that maintaining the "tone" of 
the remaining neurons, by using AMPAKINEs to increase the effectiveness of 
the excitatory input that is still available, will slow this cascade of 
neuronal death.

The first major results of AMPAKINE testing in animal behavioral models of 
learning and memory were reported in early 1994 in the prestigious journal 
PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES. In these studies, which 
involved tests of both short- and long-term memory, AMPAKINE-treated rats 
performed significantly better than untreated control animals. The authors 
concluded that "facilitation of [excitatory] transmission causes a general 
improvement in memory encoding."

                                       17

Perhaps the most compelling of the animal studies conducted to date involved 
an assessment of the effects of an AMPAKINE on memory performance in 
middle-aged rats. A number of researchers have demonstrated that healthy 
middle-aged rats have significant deficits in memory performance when 
compared to younger animals. This provides, in essence, an animal model for 
age-associated memory impairment in humans. In the study, which was published 
last year in SYNAPSE, the authors found that middle-aged rats showed striking 
deficits in performance on a maze task when compared with young adult 
animals, but when they were administered an AMPAKINE their performance was 
improved to levels equivalent to those found in young animals.

In these and other preclinical studies, the experimental compounds 
demonstrated pharmaceutically attractive qualities, including apparent low 
toxicity, rapid onset of action, rapid excretion and an ability to freely 
cross the blood-brain barrier (a semi-permeable barrier that prevents many 
drugs from getting into the brain).

Three human clinical studies have now been completed with CX516 ("AMPALEX"). 
The results of the two most recent studies were announced in the year ended 
June 30, 1996. 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.

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, 
including levels that exceeded the expected therapeutic range. At all 
dosages, 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 
were able to remember only about one-fourth as many syllables as their 
younger counterparts. In the presence of drug, the positive effect on memory 
performance that was seen in the earlier study was replicated. In fact, 
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. The 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 again noted in the drug group.

On the basis of the very encouraging results that were obtained in these 
three studies, Cortex plans to initiate additional studies in the target 
patient population, those experiencing deficits of memory and cognition due 
to Alzheimer's disease.

The first step in moving to the patient population is to ensure that the drug 
is safe in those affected by the disease. To address this issue, and to 
obtain a preliminary indication of effects on delayed recall, Cortex is 
working with clinical investigators at the National Institutes of Health who 
plan to conduct a U.S. Phase I/II study in 16 to 20 Alzheimer's disease 
patients. The double-blind, placebo-controlled dose escalation study will 
involve administration of CX516 to patients for up to 28 consecutive days.

While preliminary indications of the desired effects on memory and cognition 
may be obtained from this study, psychological testing of patients with 
Alzheimer's disease is characterized by a high level of variability. 
Full-scale Phase II studies designed to achieve significance on broad 
psychological scales will require larger numbers of patients. The Company is 
hopeful that the results from this preliminary study will encourage 
prospective pharmaceutical company partners to commit the financial and other 
resources to undertake additional clinical studies.

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. schizophrenics 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, loss of emotional responsiveness and 
expressiveness) and COGNITIVE SYMPTOMS (disordered thought and attentional 
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. 
The most common side effect 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 first studied in the 1970s, but clinical 
trials were halted due to the risk of a fatal blood disorder known as 
agranulocytosis, and also 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 controlled on typical neuroleptics, either because of 
lack of efficacy or side effects. Risperidone is another recent 
clozapine-like anti-psychotic.

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 the cognitive symptoms of schizophrenia are not addressed by any 
available agents. It is the persistence of these cognitive symptoms that 
keeps all but a few schizophrenic patients from successfully reintegrating 
into society.

Schizophrenia has long been thought to have its biochemical basis in an 
overactivity of dopamine pathways projecting into certain regions of the 
brain. More recently, a developing body of evidence in the scientific 
literature suggests that schizophrenia also involves an underactivity of 
glutamate pathways projecting into the same areas. 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 that Professor John Larson, a University of 
California, Irvine neuroscientist and Cortex consultant, found that an 
AMPAKINE reduced stereotypic behavior (mechanical repetition of posture or 
movement) in rats injected with methamphetamine. Reduction of 
methamphetamine-induced stereotypic behavior is widely used for initial 
screening of anti-psychotic drugs. The results have now been extended by 
scientists at both UCI and Cortex to include several additional AMPAKINEs. 
More recently, Cortex scientists have demonstrated that AMPAKINEs and either 
conventional or atypical  anti-psychotic drugs have additive effects in this 
model system.

The Company is presently involved in discussions with clinical researchers 
working in the schizophrenia field, and plans to initiate a small Phase I/II 
study with CX516 in schizophrenic patients in fiscal 1997. This study will 
primarily be designed as a safety study, but psychological testing will be 
conducted in an attempt to obtain a preliminary indication that CX516 has a 
beneficial effect on the symptoms of the disease, particularly the cognitive 
symptoms that have thus far been resistant to treatment.

CALPAIN INHIBITOR PROGRAM

Since 1989, the Company has been involved in research and early product 
development of inhibitors of the enzyme calpain. 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. These include brain damage 
following stroke or head injury and spasming of blood vessels (vasospasm).

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, which is due to a blockage of blood flow, and hemorrhage stroke, in 
which a blood vessel bursts in the brain. In either case, the insult to the 
brain is often immediately life-threatening and initiates a cascade of 
molecular events that ultimately leads to permanent brain damage. Each year 
more than 500,000 Americans experience a stroke. Approximately 150,000 die, 
and most survivors are left with some degree of permanent residual disability 
due to damage to brain tissue. Although stroke is the third leading cause of 
death in the U.S., no satisfactory therapy yet exists to limit or reverse the 
brain damage brought on by this condition.

Interruption of the supply of oxygen and nutrients to the brain following a 
stroke is not in and of itself responsible for the widespread destruction of 
neurons that often follows. Rather, it is believed that these disruptions 
trigger biochemical changes that lead over a period of hours or days to death 
of the affected neurons. It is now fairly well accepted that this crucial 
period of time between a stroke and the actual death of brain cells provides 
a "window of opportunity" during which key chemical events can potentially be 
blocked, to limit or prevent damage to nerve cells and thereby maintain their 
viability until homeostasis is re-established following an ischemic episode. 

Ischemia-induced release of the neurotransmitter glutamate appears to 
initiate the cascade. Glutamate builds up in the extra-cellular space 
following a stroke, stimulating receptors and allowing an excessive amount of 
calcium to enter nerve cells. Calcium control systems become overwhelmed, 
intracellular calcium concentrations rise high above normal physiological 
levels, and several calcium-dependent enzymes are activated. Of particular 
concern is calpain, which when activated, degrades the neuron's cytoskeleton 
as well as regulatory proteins such as protein kinase C. This causes 
progressively greater damage, and eventually the cell is no longer able to 
recover.

In calendar 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, which was 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 
sublicense, to commercialize products using the Company's calpain inhibitor 
technology for products for the prevention or treatment of acute and chronic 
neurodegenerative diseases and disorders of the nervous system.

Subsequently, Cortex shifted its own emphasis into calpain inhibitor research 
outside the nervous system. The Company was particularly active in 
investigating the potential role of calpain inhibitors as therapeutics for 
the treatment of vasospasm and restenosis, two serious vascular disorders. 
The Company established research collaborations and began screening compounds 
for these purposes, and reported on its progress in its 1993 annual report. 
This report of progress 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. On November 19, 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.

On October 5, 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 subsequent to October 6, 
1992. 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

                                       20

defined and subject to certain limitations. The Company has reinstituted an 
active research program on calpain inhibitors, and recently confirmed in an 
animal model the earlier finding that calpain inhibitors are capable of 
blocking vasospasm. Cortex presently intends to seek, with the assistance of 
its advisor, Vector Securities International, Inc., a larger pharmaceutical 
company partner for the further development of the calpain inhibitor 
technology.

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 into 
arrangements for manufacturing of its proposed products on favorable terms.

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. However, in entering into such arrangements, the 
Company will seek to retain the right to co-promote certain products in the 
United States to selected medical specialties (such as geriatric physicians, 
neurologists and psychiatrists). The Company believes that these specialties 
can be effectively addressed with a relatively small sales force. There is no 
assurance that the Company will be able to enter into co-promotional 
arrangements in connection with its licensing activities, or that any 
retention of co-promotional rights will lead to greater revenues for the 
Company.

TECHNOLOGY RIGHTS AND COLLABORATIVE AGREEMENTS

AMPA RECEPTOR MODULATING COMPOUNDS

Effective June 25, 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. Under the agreement, the Company paid an 
initial license fee and is obligated to make additional payments, including 
license maintenance fees 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 
begin paying royalties on net sales.

CALPAIN INHIBITORS

Effective February 11, 1991, Cortex entered into a series of agreements with 
Georgia Tech Research Corporation, the licensing arm of the Georgia Institute 
of Technology ("Georgia Tech"), under which Cortex secured exclusive 
commercial rights, for selected disorders, to several novel classes of 
chemical compounds that the Company has demonstrated are effective as calpain 
inhibitors. Under the agreement, the Company paid an initial license fee and 
is obligated to make additional payments, including license maintenance fees 
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 begin paying 
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, a number of issued U.S. patents and a range of U.S. patent 
applications and their international counterparts.

There can be no assurance that issued 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
can also 

                                       21

<PAGE>

be 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 
can be no assurance that others will not obtain patents that the Company 
would need to license or design around in order to practice its patented 
technologies, or that licenses that might be required to practice these 
technologies due to patents of others would be available on reasonable terms. 
Additionally, there can be no assurance that any unpatented manufacture, use 
or sale of the Company's technology, processes or products will not 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 can be 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 meaningfully protect its rights in such unpatented 
proprietary technology or that others will not wrongfully obtain such 
technology.

On December 8, 1994, the United States adopted the Uruguay Round Agreements 
Act ("URAA") to implement the General Agreement on Tariffs and Trade 
("GATT"). The URAA significantly alters many United States intellectual 
property laws. One of the most significant changes is to patent term length. 
Any patent issued on an application filed on or after June 8, 1995 will have 
a term that begins on the date the patent issues and ends 20 years from the 
earliest United States filing date claimed in the patent. This is in contrast 
to the 17-year term measured from the patent issue date, which has been the 
law in the United States for nearly two centuries. Given the significance of 
this change, the new law has a transition provision that applies to patents 
issuing on applications filed before June 8, 1995 and to all patents still in 
force on June 8, 1995. The term for these patents is the longer of either 17 
years from the date of issuance or 20 years from the earliest United States 
filing date. These changes are not presently expected to have a material 
impact on the Company's business.

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 has 
historically been 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. While the Company plans to conduct or 
facilitate exploratory Phase I/II studies in the U.S. with CX516 in 
Alzheimer's disease patients and in schizophrenics, it is the Company's 
intent that a larger pharmaceutical company partner or partners, which the 
Company is seeking, will pursue the required regulatory approvals to conduct 
full-scale clinical tests in the United States and elsewhere.

The FDA must concur with an IND application before human clinical testing of 
an investigational drug can begin in the United States. An IND application 
includes the results of preclinical studies evaluating the potential safety 
and efficacy of the drug, and a detailed description of the clinical 
investigations to be undertaken.

Clinical trials are normally conducted in three phases. Phase I trials are 
concerned primarily with the 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

                                       22

<PAGE>

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 from two 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 is also lengthy and on average takes approximately two 
and one-half years.

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.

In late 1992, legislation was enacted that imposed user fees on manufacturers 
of prescription drugs, antibiotic and biological products. Such fees will now 
be required for each application submitted for FDA review, with additional 
annual product and establishment fees being imposed as well. The revenues 
raised by these fees are earmarked specifically to increase the resources of 
the FDA, and by so doing to increase the speed with which the FDA reviews and 
approves drug and biological product marketing applications. By fiscal 1997, 
the user fee established by the legislation for an NDA will be $233,000, 
while the annual establishment fee will be $138,000. The legislation provides 
small companies (I.E., companies with fewer than 500 employees that are not 
currently marketing a prescription drug product) with a reduction in the 
initial application fee, and contains provisions for fee waivers. The Company 
is unable to predict the impact of this or similar user fee legislation upon 
its product development plans.

Under FDA regulations, sponsors of promising investigational drugs and 
biologics for certain immediately life-threatening or serious diseases may 
make those drugs or biologics available for treatment of patients prior to 
approval of an NDA. Cortex believes, therefore, that it, or its licensees, 
may be able to distribute certain of its proposed products, in limited 
fashion, while still in the clinical testing stage. However, because of the 
limitations imposed on commercialization under this program, this is not 
expected to be of significant economic benefit.

There can be no assurance that any required FDA or other governmental 
approval will be granted or, if granted, will not be withdrawn. Governmental 
regulation may prevent or substantially delay the marketing of 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 and, accordingly, will be dependent on entering into joint 
ventures or other collaborative arrangements with third parties with the 
required resources in order to obtain the needed approvals. Cortex intends to 
enter into license or other arrangements with larger pharmaceutical companies 
under which those companies would conduct the required clinical trials and 
bear the expenses of obtaining FDA approval for most or all of its proposed 
products. There can be 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.

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 number of drugs intended for the 
treatment of Alzheimer's disease, age-related cognitive deficits, stroke and 
other neurodegenerative diseases and disorders are on the market or in the 
later stages of clinical testing. For example, 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.

                                       23

<PAGE>

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 disorders, the Company does not have the resources, and does not 
presently intend, to compete with major pharmaceutical companies in the areas 
of later stage 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. The Company maintains 
liability insurance with coverage limits of $5 million per occurrence and $5 
million in the annual aggregate. Although the Company has never been subject 
to a product liability claim, there can be no assurance 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. Further, if AMPALEX or any other compound is approved by the 
FDA for marketing, there can be no assurance that adequate product liability 
insurance will be available, or if available, that it will be available at a 
reasonable cost. Any adverse outcome resulting from a product liability claim 
could have a material adverse effect on the Company's business, financial 
condition and results of operations.

EMPLOYEES
   
As of November 30, 1996, Cortex had 19 full-time employees and one part-time 
employee and had engaged 11 part-time Ph.D.-level scientific consultants. Of 
the 19 full-time employees, 14 are engaged in research and development and 
five are engaged in management and administrative support. The Company also 
sponsors a substantial amount of research in academic laboratories at the 
University of California, Irvine, Wake Forest University and New York 
University.
    
FACILITIES

The Company leases approximately 30,000 square feet of office, research 
laboratory and expansion space under an operating lease that expires May 31, 
1999, with an additional five-year option at 95% of the then fair market 
rental rate. 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.

EMPLOYMENT AND CONSULTING AGREEMENTS

Dr. Vincent F. Simmon joined the Company as President and Chief Executive 
Officer in May 1996. His one-year employment agreement entitles Dr. Simmon to 
a base salary of $200,000 per year as well as an annual bonus of from 15% to 
50% of his base salary, at the discretion of the Board of Directors of the 
Company. In addition, Dr. Simmon received a one-time signing bonus of 
$20,410. In connection with his employment, Dr. Simmon was granted options to 
purchase 180,000 shares of Common Stock at an exercise price of $5.625 per 
share, representing 100% of the fair market value as of the grant date. The 
options vest evenly each month over a three-year period commencing one month 
from the date of grant and have a ten-year term.

Mr. Hagen entered into a three-year employment agreement with the Company, 
commencing September 1, 1988. The employment agreement was renewed for 
additional one-year terms as of September 1, 1991, 1992 and 1993, and was 
amended and extended effective January 1, 1996 for a term ending December 31, 
1996. The agreement provided for a base salary of $132,500 with an annual 
bonus of between $10,000 and $30,000. In December 1993, options to purchase a 
total of 14,000 shares of Common Stock at an exercise price of $2.50 per 
share, which were originally granted in 1989, were extended by the Stock 
Option Committee for an additional three-year period, or until February 1997. 
The aggregate difference between exercise price and fair market value of the 
Common Stock on the date of the extension has been recorded as compensation 
expense. In the event that Mr. Hagen's employment is terminated other than 
for cause or as a result of his voluntary resignation, death or disability, 
he will receive a severance payment equal to six months' salary.

In February 1993, the Company entered into a three-year employment agreement 
with Mr. Steigrod. Mr. Steigrod resigned as President and Chief Executive 
Officer as of October 31, 1995. Under the agreement, Mr. Steigrod was 
entitled to a base salary of $210,000 per year with an annual bonus at the 
discretion of the Board of Directors of the Company, in cash and/or equity 
equal to between 15% and 50% of his base salary. In connection with his 
employment, Mr. Steigrod was granted options to purchase an aggregate of 
180,000 shares of Common Stock, of which 100,000 shares have an exercise 
price of $8.75, the fair market value on the date of grant, and 80,000 shares 
have an exercise price of $4.375, representing 50% of fair market value on 
the date of grant. The options were 20% vested on the date of grant with the 
balance vesting periodically through January 31, 1998. In March 1995, 100,000 
of these options were canceled and reissued as options to purchase 100,000 
shares of common stock at $3.50 per share, the then fair market value of the 
common stock. Options to purchase an additional 95,600 shares with an 
exercise price of $9.375 per share, representing 100% of then fair market 
value, were granted to Mr. Steigrod on December 1, 1993 pursuant to a 
one-time anti-dilution provision in his employment agreement. These options 
were canceled on March 23, 1995 and reissued as options to purchase 65,560 
shares of common stock at an exercise price of $3.50 per share, the then fair 
market value of the common stock, and options to purchase


                                       29

<PAGE>

30,040 shares of common stock at $4.50 per share. Such options have a term 
and vesting provisions identical to the options described above. In June 
1995, Mr. Steigrod's annual salary was voluntarily decreased by $10,000. In 
October 1995, Mr. Steigrod resigned as President and Chief Executive Officer.

Drs. Carl W. Cotman and Gary S. Lynch (both of whom are co-founders and 
Scientific Directors of the Company) have each entered into a consulting 
agreement with the Company that provides for the payment of an annual 
consulting fee of $30,000. In December 1993, Dr. Lynch was awarded a bonus of 
$25,000 by the Board of Directors in recognition of his contributions to the 
AMPAKINE-TM-program. In September 1994, and again in July 1995, his 
consulting fee was increased to $50,000 and $75,000 per year, respectively. 
Also in September 1994, Dr. Cotman's consulting fee was increased to $33,000 
per year. The term of each consulting agreement commenced in November 1987 
and will continue until terminated by the respective parties thereto. The 
consulting agreements obligate the respective consultants to make themselves 
available to the Company for consulting and advisory services for an average 
of three days per month. In June 1995, each of the consultants voluntarily 
reduced their annual consulting fees by $10,000. In December 1993, the Board 
of Directors instructed its Stock Option Committee to annually review the 
contributions of Drs. Cotman and Lynch and to grant stock options in 
recognition of those contributions, and to encourage future contributions, to 
them in such amounts as are deemed appropriate by the Committee. On December 
13, 1993, the Committee granted options to purchase 5,000 shares of Common 
Stock, with an exercise price equal to 100% of fair market value of the 
Common Stock on the date of grant and vesting over a three-year period, to 
each of Drs. Cotman and Lynch. On the same date, an additional option to 
purchase 7,000 shares of Common Stock, with an exercise price equal to 100% 
of fair market value of the Common Stock and full vesting on the date of 
grant, was granted to Dr. Lynch in recognition of his contributions to the 
AMPAKINE-TM-program. On March 24, 1994, the Committee granted options to 
purchase 5,000 shares of Common Stock, with an exercise price equal to 100% 
of fair market value of the Common Stock on the date of grant and vesting 
over a three-year period, to each of Drs. Cotman and Lynch. On December 15, 
1994, the Committee granted options to purchase 20,000 shares of Common Stock 
with an exercise price of $3.125 per share, the then fair market value, and 
vesting over a four-year period to Dr. Cotman. On the same date, Dr. Lynch 
was granted options to purchase 70,000 shares of Common Stock at the same 
exercise price, and with the same vesting period. On January 4, 1996, the 
Stock Option Committee granted options to Dr. Lynch to purchase 100,000 
shares of Common Stock with an exercise price of $3.50 per share, the then 
fair market value, and immediate vesting. See also "Director Compensation."

Dr. Davis L. Temple, a director of the Company, signed a consulting agreement 
with the Company that includes the payment of consulting fees of $10,000 for 
each six months of service. On February 27, 1995, the Stock Option Committee, 
in recognition of his contributions to the Company, granted Dr. Temple an 
option to purchase 20,000 shares of the Company's common stock at an exercise 
price of $2.125 per share, representing the fair market value of the common 
stock on that date. See also "Director Compensation."

DIRECTOR COMPENSATION

Each non-employee director (other than those who join the Board of Directors 
to oversee an investment in the Company) receives $1,500 at each Board of 
Directors meeting attended, and an additional $750 annual retainer for each 
committee on which he or she serves.
   
Under the Company's 1996 Stock Incentive Plan, 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 each anniversary date of the dates of grant, and will otherwise 
be subject to the terms and provisions of the 1996 Stock Incentive Plan.

                                 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 will continue 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 such officers and 
directors as permitted by applicable law.

On July 23, 1993, the Company entered into an agreement with Vector 
Securities International, Inc. ("Vector"), under which it was agreed that 
Vector would serve the Company through November 30, 1995 as exclusive 
financial advisor in financial transactions and corporate partnering 
activities, as placement agent in future private offerings of securities of 
the Company and as co-managing underwriter in future public offerings of 
securities of the Company. In connection with the agreement, Vector was paid 
a $50,000 financial advisory fee and was issued a five-year non-redeemable 
warrant to purchase 11,448 shares of Common Stock, as adjusted and subject to 
further adjustment. The Company also granted Vector a right of first refusal 
to act as co-managing underwriter in any public offering or as placement 
agent in any private placement completed prior to December 1, 1995. See 
"Description of Securities--Vector Warrants."

As consideration for its agreement to provide financial advisory services 
related to corporate finance transactions and corporate partnering 
activities, as amended and extended November 29, 1994, Vector was paid an 
additional cash retainer of $50,000 and was issued a six-year non-redeemable 
warrant to purchase 38,293 shares of the Company's common stock at $4.57 per 
share, as adjusted and subject to adjustment under certain circumstances. 
Warrants to purchase 5,471 shares of the Company's common stock vested 
immediately, and warrants to purchase 16,411 shares of the Company's common 
stock shall vest upon the consummation of each strategic alliance when and as 
secured by Vector. Such strategic alliance may include, but is not limited 
to, a joint venture, partnership, license or other contract for the research, 
development, manufacture, distribution, sale or other activity relating to 
the Company's present or future products, the sale of any of the Company's 
assets or any rights in respect to its products or technology, or a 
commitment to provide funding for all or part of the Company's research and 
development activities. For its financial advisory assistance related to the 
licensing of the Company's calpain inhibitor technology, in January 1995 the 
Company paid a $20,000 cash retainer and issued to Vector a five-year 
non-redeemable warrant to acquire 50,000 shares of the Company's common stock 
at $3.00 per share, subject to adjustment under certain circumstances. The 
Company may be required to make substantial additional payments for each 
strategic alliance secured by Vector. If a sale of the Company as presented 
by Vector is consummated, Vector may be entitled to receive a fee based on 
the aggregate consideration to be received by the Company. See "Description 
of Securities--Vector Warrants."

2,750,000 shares of Common Stock, for which Vector acted as placement agent, 
the Company issued to Vector a similar 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 (see "Business--Legal Proceedings"), this warrant was canceled 
and 


                                       33

reissued as a new warrant to purchase 234,637 shares of the Company's common 
stock at $5.37 per share, as adjusted and subject to further adjustment, at 
any time through January 15, 2000.

As consideration for its agreement to provide financial advisory services 
related to corporate finance transactions and corporate partnering 
activities, as amended and extended November 29, 1994, Vector was issued a 
six-year non-redeemable warrant to purchase 38,293 shares of the Company's 
common stock at $4.57 per share, subject to adjustment under certain 
circumstances. Warrants to purchase 5,471 shares of the Company's common 
stock vested immediately, and warrants to purchase 16,411 shares of the 
Company's common stock shall vest upon the consummation of each strategic 
alliance, as defined, when and as secured by Vector.

For its financial advisory assistance related to the licensing of the 
Company's calpain inhibitor technology, in January 1995 the Company issued 
Vector a five-year non-redeemable warrant to acquire 50,000 shares of the 
Company's common stock at $3.00 per share, subject to adjustment under 
certain circumstances, such as stock splits or stock dividends.

On December 8, 1995, in connection with the issuance of 160 shares of Series 
C Preferred Stock for an aggregate of $4,000,000, the Company issued to 
Swartz Investments, Inc. a five-year non-redeemable warrant to purchase 
106,195 shares of the Company's Common Stock at an exercise price of $2.825.

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 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, for an 
effective conversion price of $7.50 per share, subject to adjustment under 
certain circumstances (such as a stock dividend or a stock split) that result 
in an increase in the number of shares of Common Stock outstanding. 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 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 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 (such as a stock dividend or a stock 
split) that result in an increase in the number of shares of Common Stock 
outstanding.

Shares of the Series D Preferred Stock do not entitle the holder to vote for 
the election of directors or upon any other matter presented to the 
stockholders, except to the extent provided by law. Each share of Series D 
Preferred is convertible into common stock at an effective per share 
conversion price that is the lower of (I) 110% of the average closing bid 
price for the five trading days immediately preceding the closing date 
($2.9425 for the first tranche) or (ii) that price that is 18% below the 
average closing bid price for the five trading days immediately preceding the 
conversion date, in each case subject to adjustment at the rate of six 
percent per annum based on the length of the period from issuance of the 
Series D Preferred until its conversion. Pursuant to the Series D Preferred 
Stock subscripion documents, the purchaser of the Series D Preferred Stock is 
prohibited from converting any portion of the Series D Preferred Stock which 
would result in the purchaser being deemed the beneficial owner, in 
accordance with the rules of the Securities and Exchange Commission, of five 
percent or more of the then issued and outstanding Common Stock of the 
Company. The Company intends to sell a second tranche of 150 shares of Series 
D Preferred 15 days following the effectiveness of a registration statement 
covering resales of common stock issuable upon conversion of the Series D 
Preferred, and a third tranche of 150 shares 60 days following the closing of 
the second tranche. Holders of the Series D Preferred have a liquidation 
preference, after payment of full liquidation preference to holders of the 9% 
Preferred and Series B Preferred, of an amount equal to $10,000 per share, 
plus $600 per share for each year that such share is outstanding. Shares of 
Series D Preferred automatically convert into common stock on that date which 
is two years from the date of issuance of such shares.
    
   
The Restated Certificate of Incorporation of the Company authorizes the 
issuance of 5,000,000 shares of Preferred Stock, of which 549,340 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, Series B Preferred Stock, and Series D 
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.

(1)  Ashline Ltd. purchased 100 shares of Series D Preferred Stock in October 
     1996 and, subject to certain conditions outside the control of Ashline 
     Ltd. is obligated to purchase an additional 300 shares of Series D 
     Preferred Stock.  The Series D Preferred Stock is converible into Common 
     Stock at a conversion price that may vary.  See "Description of 
     Securities -- Preferred Stock" and Note 10 of Notes to Financial 
     Statements.  As a result, the exact number of shares of Common Stock 
     into which such shares of Series D Preferred Stock may be convertible, 
     and the number of shares of Common Stock which may be sold by Ashline 
     Ltd. is not presently determinable.  In order to provide for the effects 
     of possible future declines in the market value of the Company's Common 
     Stock, and in accordance with the terms of the subscription documents 
     for the Series D Preferred, an effective conversion price of $1.19 per 
     share has been assumed, representing 50% of the conversion price that 
     would apply were all of the shares of Series D Preferred converted into 
     shares of Common Stock on the date of filing of the Registration 
     Statement of which this Prospectus is a part and an aggregate of 
     3,361,345 shares have been registered for resale by Ashline Ltd. See

                                 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 Nasdaq 
in negotiated transactions, by writing options on the Shares or by a 
combination of these methods, at fixed prices which 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.

                  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, 1996 and 1995, and the 
related statements of operations, stockholders' equity and cash flows for 
each of the two years in the period ended June 30, 1996 and for the period 
from inception (February 10, 1987) through June 30, 1996. 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, 1996 and 1995, and the results
of its operations and its cash flows for each of the two years in the period 
ended June 30, 1996 and for the period from inception (February 10, 1987) 
through June 30, 1996, in conformity with generally accepted accounting 
principles.

THE THREE-MONTH PERIOD ENDED SEPTEMBER 30, 1996 ARE NOT NECESSARILY 
INDICATIVE OF THE RESULTS THAT MAY BE EXPECTED FOR THE FISCAL YEAR ENDING 
JUNE 30, 1997.

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 development activities.

BASIS OF PRESENTATION; DEVELOPMENT STAGE ENTERPRISE -- From inception through 
September 30, 1996, the Company has generated only modest operating revenues 
and has incurred losses aggregating $26,411,152. 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 can 
be no assurance that the Company will be successful in these areas. To 
supplement its existing resources, the Company is exploring several near-term 
alternatives for raising additional capital, including corporate partnership 
arrangements and the issuance of additional securities. The Company is 
planning to raise additional capital through the sale of debt or equity. When 
the Company proceeds with a debt or equity financing, there can be no 
assurance that funds will be available on favorable terms, or at all. If 
additional funds are raised by issuing equity securities, dilution to 
existing stockholders is likely to result. See Note 10.

The Company is seeking collaborative or other arrangements with larger 
pharmaceutical companies, 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 the Company is 
developing. Because of the current adverse market conditions for 
biopharmaceutical company financings, the competition for corporate 
partnering arrangements with major pharmaceutical companies has become very 
intense, with a large number of biopharmaceutical companies attempting to 
satisfy their short-term funding requirements through such arrangements. 
Accordingly, although the Company is presently engaged in discussions with a 
number of candidate companies, there can be 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-term or long-term funding requirements.

REVERSE STOCK SPLIT; AUTHORIZED SHARES -- On January 11, 1995, the Company 
effected a one-for-five reverse stock split of its common stock and revised 
the authorized number of shares of common stock from 50,000,000 to 
20,000,000, with no change in the par value of $0.001 per share. The 
accompanying financial statements and all references to the number of shares 
and per share amounts have been adjusted to reflect the effect of the reverse 
split.

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

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 

                                       F-10

<PAGE>

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.

STOCK-BASED COMPENSATION -- In November 1995, the Financial Accounting 
Standards Board issued Statement of Financial Accounting Standards No. 123 
"Accounting for Stock-Based Compensation" ("FAS 123"). The Company has 
elected to continue accounting for stock options under APB No. 25 "Accounting 
for Stock Issued to Employees." The adoption of FAS 123 was not expected to 
have a material effect on the Company's financial position or results of 
operations for the year ended June 30, 1996.

LONG-LIVED ASSETS -- In March 1995, the Financial Accounting Standards Board 
issued Statement of Financial Accounting Standards No. 121 "Accounting for 
Impairment of Long-Lived Assets to be Disposed Of" ("FAS 121") which requires 
impairment losses to be recorded on long-lived assets used in operations when 
indicators of impairment are present and the undiscounted cash flows 
estimated to be generated by those assets are less than the assets carrying 
amount. FAS 121 also addresses the accounting for long-lived assets that are 
expected to be disposed of. The Company's adoption of FAS 121 in the first 
quarter of fiscal 1996 did not have a material effect on the Company's 
financial position or results of operations.

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 during the period, and 
incorporates preferred stock dividends that accrued during the period. 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.

RESEARCH AND DEVELOPMENT COSTS -- All costs related to research and 
development activities are treated as expenses in the period incurred.

NOTE 3 -- 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"); and 160 shares have been designated as 
Series C Convertible Preferred Stock (non-voting, "Series C Preferred"); and 
549,840 shares are presently undesignated and may be issued with such rights 
and powers as the Board of Directors may designate.


                                       F-11

<PAGE>

The 9% Cumulative Convertible Preferred Stock as of September 30, 1996, June 
30, 1996 and June 30, 1995 consisted of 110,000, 110,000 and 370,000 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, 1996, June 30, 1996 and June 30, 1995 were 
$64,350, $64,350 and $183,150, respectively. In September 1995, holders of 
260,000 shares of 9% Preferred converted their shares into 34,667 shares of 
the Company's common stock. 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, 1996, June 30, 1996 
and June 30, 1995 consisted of 150,000, 150,000 and 525,000 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. In September 1995, holders of 375,000 shares 
of Series B Preferred converted their shares into 36,793 shares of the 
Company's common stock. 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 at September 30, 1996 and June 30, 1996 
consisted of 25 and 35 shares, respectively, of an original 160 shares of 
Series C Preferred issued in a private placement completed in December 1995. 
Each share of Series C Preferred is convertible into common stock in 
accordance with a formula that is indexed to the average bid price of the 
Company's common shares. Holders of the Series C Preferred have a liquidation 
preference, after payment of full liquidation preference to holders of 9% 
Preferred and in parity with the Series B Preferred, of an amount equal to 
$25,000 per share, plus an amount equal to $2,500 per share per year. Upon 
receipt of a notice of conversion from a Series C Preferred Stock holder, the 
Company may elect to redeem the shares for a price equal to the closing bid 
price on the date of conversion multiplied by the number of shares of common 
stock issuable upon such conversion. On December 8, 1997 each share of Series 
C Preferred then outstanding will automatically convert into common stock at 
the conversion price then in effect. The Company may redeem the Series C 
Preferred at any time, subject to certain restrictions, at a redemption price 
ranging from 115% to 130% of the liquidation preference.

NOTE 4 -- COMMON STOCK AND COMMON STOCK PURCHASE WARRANTS

In July 1989, the Company completed an initial public offering of 1,100,000 
Units, with each Unit consisting of 0.6 shares of common stock and two 
redeemable Class A warrants, for an aggregate of 660,000 shares of common 
stock and 2,200,000 Class A warrants. Each Class A warrant entitled the 
holder to purchase 0.26 shares of common stock and one redeemable Class B 
warrant at a price of $10.62 per share of common stock, as adjusted. During 
the year ended June 30, 1992, ten Class A warrants were exercised. The 
balance of the Class A warrants, and the Class B warrants issuable upon 
exercise of the Class A warrants, expired on December 31, 1995.

In 1991, the Company issued 1,060,417 Class C warrants in a private placement 
transaction. Each Class C warrant entitled the holder to purchase 0.26 shares 
of common stock at a price of $9.185 per share, as adjusted. None of the 
Class C warrants were exercised prior to their expiration on December 31, 
1995.

In connection with its agreement with Alkermes, Inc. ("Alkermes"; Note 6), 
the Company sold Alkermes 150,000 shares of common stock and issued 
non-redeemable warrants to Alkermes to purchase an additional 400,000 shares 
of common stock, for aggregate consideration of $1,500,000. The warrants have 
since expired.


                                       F-12

<PAGE>

In October 1993, the Company sold 103,577 shares of common stock at a price 
of $6.40 per share. The shares were acquired by four non-U.S. purchasers in a 
private placement transaction pursuant to Regulation S of the Securities and 
Exchange Commission.

In December 1993, the Company completed a private placement of 2,750,000 
shares of common stock at a price of $5.00 per share. The shares were 
acquired by 39 institutional and accredited individual purchasers in a 
private placement transaction pursuant to Regulation D of the Securities and 
Exchange Commission. Vector Securities International, Inc. acted as placement 
agent for the transaction and was issued warrants in connection therewith 
(Note 8).

In connection with the December 1995 private placement of 160 shares of 
Series C Preferred Stock (Note 3), the Company issued to Swartz Investments, 
Inc., 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.

As of September 30, 1996, 283,184 shares of common stock were reserved for 
issuance upon conversion of outstanding 9% Preferred, Series B Preferred and 
Series C Preferred Stock (Note 3); 440,573 shares were reserved for issuance 
upon exercise of warrants; and 916,511 shares were reserved for issuance upon 
exercise of outstanding stock options (Note 5).

NOTE 5 -- STOCK OPTION AND STOCK PURCHASE PLANS

EMPLOYEE/DIRECTOR OPTION PLAN -- The Company's 1989 Incentive Stock Option, 
Nonqualified Stock Option and Stock Purchase Plan provides for the granting 
by the Company of options and rights to purchase up to an aggregate of 
500,000 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 terminates 
February 2, 1999, must be at least 85% of the fair market value of the common 
stock on 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 2,500 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 25% on the anniversary dates of the dates of grant. 
Non-employee directors who serve on the Board of Directors to oversee an 
investment in the Company receive options to purchase 5,000 shares of common 
stock upon commencement of service as a director and additional options to 
purchase 1,000 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 25% on the last day of each 
calendar quarter following the dates of grant. On March 23, 1995, options to 
purchase 100,000 shares of common stock at an exercise price of $8.75 per 
share previously granted to the Company's former President and Chief 
Executive Officer were canceled and reissued as options to purchase 100,000 
shares of common stock at $3.50 per share, the then fair market value of the 
common stock. As of September 30, 1996 and June 30, 1996, options to purchase 
an aggregate of 550,104 and 542,524 shares of common stock, respectively, 
were outstanding under this plan, and an additional 46,074 and 53,854 shares 
of common stock, respectively, were reserved for future option grants.

CONSULTANT PLAN -- The Company's 1989 Special Nonqualified Stock Option and 
Stock Purchase Plan provides for the granting by the Company of options and 
rights to purchase up to an aggregate of 300,000 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 
terminates February 2, 1999, must be at least 50% of the fair market value of 
the common stock on the date of grant. On May 24, 1995, options to purchase 
an aggregate of 51,000 shares of common stock previously granted to several 
consultants to 


                                       F-13

<PAGE>

the Company were repriced from a weighted average exercise price of $7.19 per 
share to $3.125 per share, the then fair market of the common stock. As of 
September 30, 1996 and June 30, 1996, options to purchase an aggregate of 
356,407 and 343,407 shares of common stock, respectively, were outstanding 
under this plan, and an additional 3,026 and 16,026 shares of common stock, 
respectively, were reserved for future option grants.

EXECUTIVE STOCK PLAN -- In 1991, in connection with his election as Chairman 
of the Board, Harvey S. Sadow, Ph.D. was granted an option to purchase 10,000 
shares of common stock at an exercise price of $2.19 per share, representing 
50% of the fair market value of the common stock on the date of grant. In 
1993, a former President and Chief Executive Officer was granted an option to 
purchase 80,000 shares of common stock at an exercise price of $4.375 per 
share, representing 50% of the then fair market value of the common stock. On 
March 23, 1995 options held by the former officer to purchase 95,600 shares 
of common stock at an exercise price of $9.375 per share were canceled and 
reissued as options to purchase 65,560 shares of common stock at $3.50 per 
share, the then fair market value of the common stock, and options to 
purchase 30,040 shares of common stock at an exercise price of $4.50 per 
share. As of September 30, 1996 and June 30, 1996, options to purchase an 
aggregate of 10,000 shares of common stock were outstanding under the 
Executive Stock Plan, and an additional 208,871 shares of common stock were 
reserved for future option grants.

As of September 30, 1996 and June 30, 1996, options to purchase an aggregate 
of 385,042 and 361,552 shares of common stock, respectively, were exercisable 
under the Company's stock option plans. During the years ended June 30, 1996 
and 1995 and the period from inception (February 10, 1987) through June 30, 
1996, options to purchase 0, 0, and 261,289 shares of common stock, 
respectively, were issued to certain directors, officers and consultants 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. 
In February 1994, an option to purchase 14,000 shares of common stock that 
was previously issued to an officer was extended for three years. The 
aggregate difference between fair market value at the time of the extension 
and the exercise price of the options was recorded as compensation expense at 
the time of the extension. Stock option compensation expense related to these 
transactions, aggregating $0, $14,139, $555,809, $42,109, $56,092 and 
$555,809 for the three-month periods ended September 30, 1996 and 1995, and 
the period from inception (February 10, 1987) through September 30, 1996, the 
years ended June 30, 1996 and 1995 and the period from inception (February 
10, 1987) through June 30, 1996, respectively, has been recorded in the 
accompanying statements of operations.

Stock option transactions under the Company's stock option plans for the two 
years ended June 30, 1996 and the three-month period ended September 30, 1996 
are summarized below:

NOTE 6 -- AGREEMENT WITH ALKERMES, INC.; LEGAL PROCEEDINGS

In January 1992, the Company entered into a development and license agreement 
with Alkermes, Inc. ("Alkermes") for the development, clinical testing and 
commercialization of the Company's calpain inhibitor products, which was 
subsequently amended in October 1992 (the "Alkermes Agreement"). Under the 
Alkermes Agreement, the Company granted to 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. Under the Alkermes Agreement, the 
Company received an aggregate of $3,100,000 in research payments over the 
18-month period ended June 30, 1993, and a $500,000 payment in October 1992 
in connection with a limited expansion of Alkermes' commercial rights. 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. On October 5, 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 subsequent to October 6, 1992. 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.

NOTE 7 -- COMMITMENTS

The Company leases its offices and research laboratories under an operating 
lease that expires May 31, 1999, with an additional five-year option at 95% 
of the then fair market rental rate. Rent expense under this lease for the 
three-month periods ended September 30, 1996 and 1995, the period from 
inception (February 10, 1989) through September 30, 1996, the years ended 
June 30, 1996 and 1995 and the period from inception (February 10, 1987) 
through June 30, 1996 was $47,000, $43,000, $1,471,000, $193,000, $232,000 
and $1,424,000, respectively. Commitments under the lease for the years 
ending June 30, 1997, 1998 and 1999 are $229,000, $235,000 and $220,000, 
respectively.

As of June 30, 1996, the Company was obligated to two executive officers 
under employment agreements expiring through May 1997 that involve annual 
salary payments aggregating $332,500 and that provide for bonuses under 
certain circumstances. Additionally, in the event that a compound developed 
by or under the supervision of a senior scientific employee of the Company is 
commercialized by the Company, the Company will be obligated under certain 
circumstances to pay the employee a royalty based on net sales, as defined 
and subject to adjustment, of products containing the compound. Also as of 
June 30, 1996, the Company was committed under scientific consulting and 
external research agreements to annual payments aggregating approximately 
$1,253,000.

The Company has entered agreements with two academic institutions that 
provide the Company exclusive rights to certain of the technologies that it 
is developing. Under the terms of the agreements, the Company is committed to 
royalty payments, including minimum annual royalties of $95,000 for the years 
ending June 30, 1997 and 1998. Thereafter, minimum annual royalties are 
$105,000 for the remaining life of the patents covering the subject 
technologies. One of the agreements commits the Company to pay up to an 
additional $875,000 dependent upon achieving clinical testing and regulatory 
approval milestones. The same institution is eligible to receive a proportion 
of certain remuneration received by the Company in connection with 
sublicensing agreements that the Company may enter into.

NOTE 8 -- RELATED PARTY TRANSACTIONS

From inception (February 10, 1987) through June 30, 1991, the Company made 
payments aggregating $1,319,112 to a founding stockholder for commissions and 
underwriting fees for private and public offerings and for interest payments 
on a note formerly held by such stockholder. No such payments have been made 
since June 30, 1991.

From inception (February 10, 1987) through June 30, 1993, the Company paid or
accrued scientific and other consulting fees to stockholders aggregating
$606,993. In the years ended June 30, 1996 and 1995, such consulting 


                                       F-15

<PAGE>
fees aggregated $87,160 and $106,583, respectively. In addition, the Company 
is obligated under certain circumstances 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 1988, the Company provided to a former officer a relocation loan in the 
amount of $100,000, bearing interest at 5% per annum, originally due in June 
1991 and subsequently extended to December 1992. The Board of Directors 
reduced the principal amount of the loan to $90,000 as of January 1, 1990 and 
to $77,400 as of July 1, 1991, with the reductions recorded as salary 
expense. The outstanding principal and accrued interest on this loan 
aggregating $96,674 was paid off by the former officer in September 1992 by 
surrender of 12,627 shares of common stock at the then fair market value.

In connection with its initial public offering in July 1989, the Company 
entered into an agreement granting a then related party entity a five-year 
right of first refusal to act as underwriter or agent for public and private 
offerings. In July 1993, the formerly related party entity agreed to 
surrender its right of first refusal to act as underwriter or agent in future 
private and public offerings of securities by the Company, in exchange for a 
cash payment of $66,000.

On July 23, 1993, the Company entered into an agreement with Vector 
Securities International, Inc. ("Vector"), under which Vector agreed to serve 
as financial advisor to the Company in connection with corporate finance 
transactions and corporate partnering of the Company's cognition enhancement 
and Alzheimer's disease programs. In connection with the agreement, the 
Company paid a $50,000 retainer and issued to Vector a five-year 
non-redeemable warrant to acquire 11,448 shares of common stock at an 
exercise price of $6.77 per share, as adjusted and subject to further 
adjustment under certain circumstances.

In connection with its services as placement agent in the 1993 private 
placement (Note 4), 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 234,637 shares of the Company's common 
stock at $5.37 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.

As consideration for its agreement to provide financial advisory services, as 
amended and extended November 29, 1994, Vector was paid a retainer of $50,000 
and was issued a six-year non-redeemable warrant to purchase 38,293 shares of 
the Company's common stock at $4.57 per share, subject to adjustment under 
certain circumstances. Warrants to purchase 5,471 shares of the Company's 
common stock vested immediately, and warrants to purchase 16,411 shares of 
the Company's common stock vest upon the consummation of each strategic 
alliance when and as secured by Vector. For an expansion in January 1995 of 
its financial advisory assistance to include the Company's calpain inhibitor 
technology, the Company paid a $20,000 retainer and issued to Vector a 
five-year non-redeemable warrant to acquire 50,000 shares of the Company's 
common stock at $3.00 per share, subject to adjustment under certain 
circumstances. The Company may be required to make substantial additional 
payments for each strategic alliance secured by Vector. If a sale of the 
Company as presented by Vector is consummated, Vector may be entitled to 
receive a fee based on the aggregate consideration received by the Company.

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, 1996, the Company had federal and California tax net operating
loss carryforwards of approximately $23,263,000 and $4,040,000, respectively.
The difference between the federal and California tax loss carryforwards is
primarily attributable to the capitalization of research and development
expenses for 

                                       F-16

<PAGE>
California franchise tax purposes and the fifty percent limitation on 
California loss carryforwards. The federal and California tax loss 
carryforwards will begin expiring in 2003 and 1996, respectively. The Company 
also has federal and California research and development tax credit 
carryforwards totaling $665,000 and $152,000, respectively, which will begin 
expiring in 2003.

Utilization of the net operating losses 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. Due to the 
equity transactions that occurred during the year ended June 30, 1996, the 
Company may have had another ownership change pursuant to Internal Revenue 
Code Section 382. If the Company is determined to have had such a change or 
if there should be future changes of ownership, these annual limitations for 
utilization of net operating loss carryforwards 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, 
1996 and June 30, 1995 are shown below. The valuation allowance related to 
deferred tax assets is $10,847,000 and $9,079,000 for the years ended June 
30, 1996 and 1995, respectively. The increase in the valuation allowance for 
the year ended June 30, 1996 of $1,768,000 is primarily due to additional 
reserves required for new deferred tax assets.

Deferred tax assets:

NOTE 10 -- SUBSEQUENT EVENTS

In October 1996, the Board of Directors designated 500 shares of a new series 
of preferred stock, the Series D Convertible Preferred Stock ("Series D 
Preferred"). Each share of Series D Preferred is convertible into common 
stock in accordance with a formula that is indexed to the average bid price 
of the Company's common shares. Holders of the Series D Preferred have a 
liquidation preference, after payment of full liquidation preference to 
holders of the 9% Preferred, Series B Preferred and Series C Preferred, of an 
amount equal to $10,000 per share, plus $600 per share for each year that 
such share is outstanding. Shares of Series D Preferred automatically convert 
into common stock on that date which is two years from the date of issuance 
of such shares.

On October 15, 1996, the Company completed the first tranche of a 
three-tranche Regulation D private placement of Series D Preferred. The 
Company sold 100 shares of Series D Preferred at a price of $10,000 per 
share, for gross proceeds of $1,000,000. The Series D Preferred issued in 
this tranche is convertible at an effective per share conversion price that 
is the lower of (i) 110% of the average closing bid price for the five 
trading days immediately preceding the closing date ($2.9425 for the first 
tranche) or (ii) that price that is 18% below the average closing bid price 
for the five trading days immediately preceding the conversion date, in each 
case subject to adjustment at the rate of six percent per annum based on the 
length of the period from issuance of the Series D Preferred until its 
conversion. The Company is preparing a registration statement covering 
resales of common stock issuable upon conversion of the Series D Preferred, 
and is to sell a second tranche of 150 shares of Series D Preferred (for 
gross proceeds of $1,500,000) 15 days following the effectiveness of such 
registration statement and a third tranche of 

                                       F-17

<PAGE>

150 shares 60 days following the closing of the second tranche. The closing 
of the second and third tranches is subject to certain conditions, which 
conditions are outside the control of the investor, including but not limited 
to minimums for price and trading volume of the Company's common stock.

                        INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law makes provision for the 
indemnification of officers and directors in terms sufficiently broad as to 
include indemnification under certain circumstances for liabilities 
(including reimbursement for expenses incurred) arising under the Securities 
Act of 1933, as amended (the "Act"). The Restated Certificate of 
Incorporation of the Company provides that the Company shall indemnify 
officers and directors to the fullest extent permitted by statute.

In addition, as permitted by Section 102(b)(7) of the Delaware Corporation 
Law, the Restated Certificate of Incorporation of the Company provides that a 
director of the Company shall not be liable to the Company or its 
stockholders for monetary damages for breach of the director's fiduciary duty 
of care. However, as provided by Delaware law, such limitation of liability 
will not act to limit liability (i) for any breach of the director's duty of 
loyalty to the Company or its stockholders, (ii) for any acts or omissions 
not in good faith or that involve intentional misconduct or a knowing 
violation of law, (iii) arising under the provision of the Delaware General 
Corporation Law relating to unlawful distributions, or (iv) for any 
transaction from which the director derived an improper benefit.

The Company has entered into indemnification agreements with each of its 
directors and officers, which provide for the indemnification of directors 
and officers of the Company against any and all expenses, judgements, fines, 
penalties and amounts paid in settlement, to the fullest extent permitted by 
law.

ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

The following table sets forth the estimated expenses of this offering 
(excluding commissions). All of the amounts shown are estimates except the 
Securities and Exchange Commission registration fee.

ITEM 26.  RECENT SALES OF UNREGISTERED SECURITIES

The following consists of information relating to unregistered securities 
sold by the Company during the past three years. Numbers of shares have been 
revised to reflect a one-for-five reverse stock split that was effected 
January 11, 1995.

    1.   On December 1, 1993, the Company sold an aggregate of 2,750,000
         shares of Common Stock to 39 accredited investors for an
         aggregate of $13,750,000, and issued a warrant to purchase
         274,200 shares of Common Stock to Vector, who acted as placement
         agent for the transaction.

    2.   On November 29, 1994, the Company issued a warrant to purchase
         38,293 shares of Common Stock to Vector, in connection with
         Vector's assistance with corporate partnering activities.

    3.   On January 20, 1995, the Company issued a warrant to purchase
         50,000 shares of Common Stock to Vector, in connection with their
         assistance in negotiating a resolution to the dispute with
         Alkermes, Inc.

                                       II-1

<PAGE>

    4.   On December 8, 1995, the Company sold an aggregate of 160 shares
         of Series C Preferred Stock to 12 overseas investors for gross
         proceeds of $4,000,000.

    5.   On December 8, 1995, the Company issued a warrant to purchase
         106,195 shares of Common Stock to Swartz Investments, Inc. in
         connection with their assistance with the foregoing placement.

    6.   On October 15, 1996, the Company sold 100 shares of Series D
         Preferred Stock to one accredited investor for gross proceeds of
         $1,000,000.

The foregoing sales of securities described in paragraphs 1,2,3,5 and 6 above 
were made in reliance upon the exemption from the registration provisions of 
the Securities Act of 1933 set forth in Section 4(2) thereof as transactions 
by an issuer not involving any public offering. The Company has reason to 
believe that all of the foregoing purchasers were familiar with or had access 
to information concerning the operations and financial condition of the 
Company, and each of the purchasers acquiring securities in exchange for cash 
consideration represented that it was acquiring the shares for investment and 
not with a view to the distribution thereof. At the time of issuance, all of 
the foregoing shares of Common Stock were deemed to be restricted securities 
for purposes of the Securities Act of 1933 and the certificates representing 
such securities bear legends to that effect. The foregoing sale of securities 
described in paragraph 4 above was made pursuant to Regulation S under the 
Securities Act of 1933.

ITEM 28.  UNDERTAKINGS

The undersigned Registrant hereby undertakes:

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

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

          (ii)   to reflect in the prospectus any facts or events arising after
                 the effective date of the registration statement (or the most
                 recent post-effective amendment thereof) which, individually or
                 in the aggregate, represent a fundamental change in the
                 information set forth in the registration statement;

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

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

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

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

For purposes of determining any liability under the Securities Act, the 
Registrant will treat the information omitted from the form of prospectus 
filed as part of this registration statement in reliance upon Rule 430A and 
contained in a form of prospectus filed by the Registrant under Rule 
424(b)(1), or (4) or 497(h) under the Securities Act as part of this 
registration statement as of the time the Commission declared it effective; 
and will treat each post-effective amendment that contains a form of 
prospectus as a new registration statement for the securities offered in the 
registration statement, and that offering of the securities at that time as 
the initial bona fide offering of those securities.
