PART I

Item 1. Business

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

The AMPAKINE program addresses large potential markets. In 2001, on a worldwide basis these markets represented sales in excess of $35 billion. The Company’s commercial development plan involves partnering with larger pharmaceutical companies for research, development, clinical testing, manufacturing and global marketing of its proposed products for those indications that require sizable, expensive Phase III clinical trials — and very large sales forces to achieve significant market penetration. At the same time, Cortex plans to develop internally a selected set of indications, many of which will allow it to apply for “Orphan Drug” status. Such designation within the Food and Drug Administration is usually applied to products where the number of patients in the given disease category is less than 200,000 per year. These indications typically require more modest investment in the development stages, follow a quicker regulatory path, and involve a more concentrated sales reach to a few, selected medical centers in the United States. If the Company is successful in the pursuit of this operating strategy, it may be able to apply for a product registration for at least one Orphan Drug indication within a four year time frame. Cortex will continue to seek at least one more significant license agreement with a larger pharmaceutical company, while the Company prepares itself for potential entrance into the pharmaceutical market with its own product.

In January 1999, the Company entered into a research collaboration and exclusive worldwide license agreement with NV Organon (“Organon”), a subsidiary of Akzo Nobel. The agreement grants Organon worldwide rights to develop and commercialize the Company’s AMPAKINE technology for the treatment of schizophrenia and depression. In October 2000, the Company entered into a research collaboration and license agreement with Les Laboratoires Servier (“Servier”). The agreement, as amended in October 2002, will allow Servier to develop and commercialize the Company’s AMPAKINE technology in defined territories of Europe, Asia, the Middle East and certain South American countries as a treatment for memory impairment associated with aging and neurodegenerative diseases. The indications covered include, but are not limited to, Alzheimer’s disease, mild cognitive impairment, sexual dysfunction, anxiety disorders and the dementia associated with multiple sclerosis and Amyotrophic Lateral Sclerosis.

Cortex continues to seek collaborative or licensing arrangements with other pharmaceutical companies. These arrangements may permit other applications of the AMPAKINE compounds to be advanced into later stages of clinical development and may provide access to the extensive clinical trials management, manufacturing and marketing expertise of such companies. The Company may not be able to secure such arrangements on favorable terms, or at all, and its products may not be successfully developed and approved for marketing by government regulatory agencies.

In the fiscal years ended June 30, 2003 and 2002, the Company’s total operating expenses were approximately $6,421,000 and $7,487,000, respectively. Amounts for fiscal year 2002 include expenses for initiating the Phase II clinical study of the AMPAKINE CX516 in patients with mild cognitive impairment and certain technology access payments related to the Company’s license of the AMPAKINE technology from the University of California.

In this annual report, the terms we, our, and us refer to Cortex Pharmaceuticals, Inc., a Delaware corporation. Our executive offices are located at 15231 Barranca Parkway, Irvine, California 92618, and our telephone number is (949) 727-3157. Our website is www.cortexpharm.com.

AMPA Receptor Program

In June 1993, Cortex licensed a new class of molecules and technology — the AMPAKINE technology — from the University of California. Cortex has subsequently been working to develop and patent new AMPAKINE molecules and to demonstrate efficacy and safety in a number of potential indications.

AMPAKINE compounds facilitate the activity of the AMPA receptor, which binds the neurotransmitter glutamate. The AMPAKINE compounds interact in a highly specific manner with the AMPA receptor in the brain, lowering the amount of neurotransmitter required to generate a response, and increasing the magnitude of the response to any given amount of glutamate. Cortex hopes that this selective amplification of the normal glutamate signal will eventually find utility in the treatment of neurological diseases and disorders characterized by depressed functioning of brain pathways that utilize glutamate as a neurotransmitter.

It is well known that synaptic connections, including those that utilize glutamate, decline with age. Thus, disorders associated with aging may be amenable to treatment with AMPAKINE compounds. Two such disorders are mild cognitive impairment and Alzheimer’s disease. Schizophrenia and other disorders that may involve neurotransmitter imbalances, including reduced levels of glutamate transmission, may also benefit from AMPA-receptor directed therapeutics. A study with AMPAKINE compounds in patients with schizophrenia indicated improvement in a number of symptoms also common to patients with Attention Deficit Hyperactivity Disorder (“ADHD”). The Company and its collaborators have obtained other encouraging preliminary results in animal models of depression, sexual dysfunction and stroke.

One of the most compelling animal studies conducted to date with the AMPAKINE compounds involved an assessment of the effects 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 an animal model for age-associated memory impairment in humans. In a study published in Synapse, the authors conducted research involving a maze task with middle-aged and young adult rats. The middle-aged rats showed striking deficits in performance when compared with the young adult animals. When given an AMPAKINE compound, the performance of the middle-aged rats improved to levels equivalent to those found in young animals.

Three human clinical safety studies have been completed with the AMPAKINE CX516 (“AMPALEX”) in healthy volunteers. In all three studies, CX516 was safe and well-tolerated on acute oral administration and, importantly, indicated statistically-significant positive effects on memory performance.

The initial study, conducted by AFB Parexel in Berlin, Germany, 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 included administering a single dose of drug in capsule form to each volunteer. Several dosages of drug were tested and at all dosage levels, the drug was safe and well-tolerated. In addition, analysis of psychological data 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, CX516 was again found to be safe and well-tolerated. The elderly volunteers were also given the same nonsense syllable memory test that had been given to the young volunteers in the first study. In the absence of drug, the elderly volunteers’ memory was substantially worse than that of the young volunteers. In the presence of drug, a statistically significant positive effect on memory performance was observed. Several of the elderly volunteers receiving the highest dosage of CX516 scored at or above the average score achieved by the young volunteers in the earlier study.

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

After these encouraging results, Cortex initiated a Phase I/IIa study in patients experiencing deficits of memory and cognition due to Alzheimer’s disease. The double-blind, placebo-controlled dose escalation study, which was conducted at the National Institutes of Health in Bethesda, Maryland, involved administration of CX516 to an eventual total of 14 patients for up to 28 days. A preliminary analysis of the data indicates improvement in ADAS-cog and CIBIC plus, two measures used to detect medication induced changes in Alzheimer’s disease patients. The ADAS-cog is an objective standard used for measuring changes in memory and cognition. The CIBIC plus is a subjective measure used by physicians to detect overall improvement in a patient’s memory.

While the clinical testing of the AMPAKINE technology initiated by Cortex provided preliminary indications of desired effects on memory and cognition, psychological testing of patients with Alzheimer’s disease is subject to a high level of variability. Full-scale Phase II studies designed to achieve significance on broad psychological scales will require larger numbers of patients. Cortex intends that further clinical studies of AMPAKINE compounds as a treatment for Alzheimer’s disease will be conducted in collaboration with its corporate partner, Servier.

In June 2000, Cortex received $247,000 from the Institute for the Study of Aging (the “Institute”), a non-profit foundation based in New York City and dedicated to the improvement in quality of life for the elderly. The funds provided support for the clinical trial conducted with Servier in patients with MCI, as explained more fully below. Data from this study may support the concept of AMPA modulation as a treatment for MCI and would justify additional, larger trials. In the event that Cortex enters one of its AMPAKINE compounds into Phase III clinical studies as a treatment for Alzheimer’s disease, Cortex has agreed to repay the funds to the Institute to allow them to financially assist other biotechnology companies.

In October 2000, the Company entered into a research collaboration and an exclusive license agreement with Servier. The agreements will enable Servier to develop and commercialize Cortex’s proprietary AMPAKINE technology for the treatment of declines in cognitive performance associated with aging and of neurodegenerative diseases. The indications covered include, but are not limited to, Alzheimer’s disease, MCI, sexual dysfunction, and the dementia associated with multiple sclerosis and Amyotrophic Lateral Sclerosis. The territory covered by the exclusive license excludes North America, allowing Cortex to retain commercialization rights in its domestic market. The territory covered by the agreement also excludes South America (except Argentina, Brazil and Venezuela), Australia and New Zealand. The agreement includes an up-front payment by Servier of $5,000,000, research support payments of approximately $2,000,000 per year for three years (subject to annual increases) and milestone payments, plus royalty payments on sales in licensed territories. In October 2002, Servier agreed to provide Cortex an additional $4,000,000 of research support over a two-year period, in exchange for rights to the Cortex AMPAKINE compounds for the potential treatment of anxiety disorders, in Servier’s licensed territories.

Mild Cognitive Impairment and Alzheimer’s Disease

Impairment of memory and cognition is a significant health care problem that is growing as the elderly population continues to increase. While not fatal (except when associated with diseases such as Alzheimer’s disease), the incidence and prevalence of cognitive deficits inevitably increase with age. Many elderly individuals are confined to nursing homes because of psychological disorientation and functional difficulties. Pharmaceuticals to alleviate deficits in memory and cognition could potentially enable these elderly individuals to remain independent longer, resulting in improved quality of life and substantial savings in health care costs. Cognitive deficit is also associated with a number of other neurological and neurodegenerative diseases, including autism, fragile X syndrome, multiple sclerosis, Amyotrophic Lateral Sclerosis and Huntington disease.

Although disease and physiological malfunctions may be the fundamental cause of severe mental decline, age itself is a contributory factor, with the human brain losing about 10% of its weight over a normal life span. In the cerebral cortex, a great deal of the communication between neurons is mediated by receptors for the neurotransmitter glutamate, including a subtype known as the AMPA receptor.

AMPA receptors and synapses decline in number with aging, on average by 25-30% between the ages of 25 and 65, making it more difficult for information to pass through and between areas of the cerebral cortex. Therefore a potential corrective approach to alleviate age-related cognitive deficits is to enhance the activity of the remaining functional AMPA receptors. AMPAKINE compounds amplify glutamate currents and have been shown to alleviate memory deficits in experiments in both elderly animals and humans.

In the aging population there is a continuum of cognitive decline. This continuum ranges from normal (for the general age group) to mild cognitive impairment (MCI) to probable Alzheimer’s disease (AD) or other types of dementia.

Patients with MCI currently represent the earliest clinically-defined group with memory impairment beyond that expected for normal individuals of the same age and education, but do not meet

clinical criteria for AD. It is estimated that there are between 3 and 4 million people with MCI. The memory deficits in the MCI population are clinically discernable and can interfere with daily functioning. MCI patients also appear to have a greatly increased risk of developing AD. Whereas approximately 1-2% of the normal elderly population will be diagnosed with AD every year, 10-15% or more of MCI patients will progress to AD per year.

Alzheimer’s disease is the most common destroyer of memory, currently afflicting some 4 million Americans and 12 million people worldwide. With the aging of our population, unless a treatment is found, the number of people in the U.S. with the disease is expected to reach 14 million by the middle of this century. According to the Alzheimer’s Association, the U.S. society spends at least $100 billion a year on Alzheimer’s disease at an average lifetime cost per patient of $174,000. Neither Medicare nor most private health insurance covers the long-term care more patients need. The impact of an effective treatment, even a symptomatic one, would be enormous.

It’s in the early stages of Alzheimer’s disease that Cortex believes AMPAKINE molecules may play a valuable role, enhancing the effectiveness of the brain cells that have not yet succumbed to the disease. This enhancement may help to alleviate the memory and cognitive deficits that make up the early symptoms.

There is also a possibility that treatment with AMPAKINE compounds may slow the progression of Alzheimer’s disease. Brain cells, or neurons, require continued input from other brain cells to remain alive. As neurons die, other neurons begin to lose their inputs, hastening their own death. AMPAKINE compounds may slow the rate at which functional levels of input from other neurons are lost. In animal models, selected AMPAKINE compounds have been shown to increase the production of BDNF, which is a protein associated with the formation of synapses by neurons. This possible mode of action also may prove beneficial to patients with Alzheimer’s disease, although it has not been demonstrated whether the same mechanism may produce similar results in humans.

In March 2001, a Food and Drug Association (“FDA”) advisory panel concluded that MCI is a distinct condition separate from Alzheimer’s disease and a valid target for new therapies — regardless of whether a new drug slows progression to dementia. The FDA indicated its willingness to approve a drug that can be shown to be safe and effective in improving memory. This decision represents a marked departure from the FDA’s prior reluctance to approve such medications, encouraging Cortex in its pursuit of developing a drug that may treat memory disorders. Cortex has rights to issued patents in the United States, Mexico and Australia covering the use of any AMPA receptor modulating compounds to improve memory and cognition. During the fiscal year ended June 30, 2003, Cortex received a notice of allowance for a similar patent in Europe.

Together with Servier, Cortex conducted a cross-national study of the AMPAKINE technology as a potential treatment for MCI. The Phase II study began enrollment in March 2002 in the United States and several months later in five European countries (France, Belgium, Great Britain, Sweden and the Netherlands). The last patient completed the study in mid-August 2003. The data is being verified and analyzed with the results anticipated in the fourth quarter of calendar year 2003, or early in the first quarter of calendar year 2004.

This cross-national study used a randomized, double-blinded, placebo-controlled parallel group design involving 175 patients who were administered CX516 or matching placebo for 28 days. Cortex, along with its partner, Servier, organized and convened an international panel of experts in MCI to aid in the design of the trial and the associated screening and outcome measures. The primary outcome measure for the trial was the 15-item word list delayed recall test. Secondary outcome measures included a number of validated objective tests to measure improvement in the speed and accuracy of functions requiring memory.

Based on our animal and limited human studies, we believe that CX516 is a short acting drug that might require multiple administrations of relatively high doses per day to achieve and maintain the desired therapeutic effect. Therefore, we and our strategic partners are investigating AMPAKINE compounds with a longer period of activity that may need to be administered only once, or possibly twice per day. A reduction in the number of doses per day is especially desirable in the treatment of chronic diseases and cognitive disorders where patient compliance is not well maintained. At the same time, we are evaluating other indications for CX516 where multiple daily dosing could be more easily accommodated.

Schizophrenia

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

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

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

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

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

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

In late 1995, Cortex announced the discovery that an AMPAKINE compound reduced stereotypic behavior (mechanical repetition of posture or movement) in rats that had been injected with methamphetamine. Reduction of methamphetamine-induced stereotypic behavior is widely used for initial screening of anti-psychotic drugs. Scientists at the University of California, Irvine and Cortex have since extended this finding to include additional AMPAKINE molecules. Further, Cortex scientists have

demonstrated that AMPAKINE compounds in combination with either conventional or atypical anti-psychotic drugs have additive or synergistic effects in this model system.

In January 1999, Cortex entered into an exclusive worldwide license agreement with Organon. The agreement will enable Organon to develop and commercialize Cortex’s proprietary AMPAKINE technology for the treatment of schizophrenia. Under the agreement, Organon has rights to intellectual property that includes broad medical use patents covering the use of any AMPA receptor modulating compound to treat schizophrenia as a mono-therapy, or in combination with other anti-psychotic medications.

The agreement also included an option for Organon to expand its rights to the technology as a potential treatment for depression. Organon exercised that option in January 2001, thereby committing to specified spending on research in the field using AMPAKINE compounds.

The agreement with Organon provided an up-front payment of $2,000,000 and research support payments of approximately $3,000,000 per year for two years. The agreement also includes milestone payments and royalty payments on worldwide sales. Cortex believes that the agreement with Organon will provide an accelerated program to bring the AMPAKINE technology to market for schizophrenia and depression, if proven safe and effective in clinical trials.

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

Further clinical testing of the AMPAKINE compounds in patients with schizophrenia is being conducted by the Company’s corporate partner, Organon. In May 2000, Cortex achieved its first milestone under the related agreement when Organon selected a licensed compound to pursue in Phase I clinical testing, triggering a $2,000,000 payment to Cortex. In September 2001, Organon informed Cortex of its intent to continue development of the selected compound by entering Phase II clinical testing, triggering a second $2,000,000 milestone payment. Additional payments from the Organon agreement for schizophrenia will depend upon the results of the Phase II study.

In September 2001, Cortex received notice of a Phase II Small Business Innovative Research (“SBIR”) award for aproximately $770,000 from the National Institutes of Health to investigate the therapeutic potential of the AMPAKINE technology in schizophrenia. The goals of the related research plan include determining whether an AMPAKINE compound will improve negative symptoms, attention and memory. The research plan also hopes to assess the effects of an AMPAKINE compound on positive systems, anxiety and depressive symptoms. As of June 30, 2003, Cortex had received $500,000 from this two-year grant award, with the term of the grant award extended for an additional one-year period.

Attention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder is the most commonly diagnosed psychological disorder of children. The National Institute of Mental Health (“NIMH”) estimates that ADHD affects three to five percent of school-age children, with about one child in every classroom in the U.S. in need of help for this disorder. According to the NIMH, national public school spending on behalf of students with ADHD may have exceeded $3 billion in 1995.

Table of Contents

Symptoms of ADHD include an inability to sustain attention and concentration, along with developmentally inappropriate levels of activity, distractability and impulsivity. Children with the disorder may have functional impairment across multiple settings including home, school and peer relationships. ADHD has also been linked to long-term adverse effects on academic performance, vocational success and social and emotional development. These effects not only impact the individual patients, but also their families, schools and communities. For many, the symptoms and impact of the disorder continue into adulthood.

Psychostimulants, including amphetamine, methylphenidate and pemoline, represent the most widely researched and commonly prescribed treatments for the disorder. One theory suggests that ADHD results from difficulties in inhibiting responses to internal and external stimuli. Evidence suggests that those areas of the brain thought to be involved in planning, foresight, and consideration of alternative responses may be under-stimulated in patients with ADHD. Stimulant medication may work on these areas of the brain to increase neural activity to more normal levels.

Because of the availability and frequent prescribing of psychostimulants, concerns over their potential overuse and abuse have intensified. Along with the abuse potential, treatments with psychostimulants may result in side effects. According to the National Institutes of Health, some children on these medications may lose weight, have less appetite and temporarily grow more slowly. Others may experience problems falling asleep. Given the lack of consistent improvement beyond the disorder’s core symptoms and the deficit of long-term studies, the need remains for additional testing with medications and behavioral treatments.

In April 1999, the Company reported preliminary results from a study with the AMPAKINE CX516 in patients with schizophrenia being treated with clozapine. The results noted in CX516-treated patients included improved performance on several tests of memory, problem solving and distractability, as well as a clinical improvement in attention — symptoms that are also common to patients with ADHD. Based upon these results, the Company believes that AMPAKINE compounds may represent a novel, non-controlled (not regulated by the Drug Enforcement Agency) approach for treating ADHD patients.

In April 2000, the Company entered an option agreement with Shire Pharmaceuticals Group, plc (“Shire”), under which Shire initiated a Phase II double-blind, placebo-controlled study of Cortex’s AMPAKINE CX516 for the treatment of ADHD. Enrollment in the study began in the summer of 2001, with Shire responsible for all of the costs of the trial. In exchange for the option, Cortex received $130,000; Shire also purchased 254,353 shares of Cortex common stock for $870,000.

Shire had the right to convert its option into an exclusive worldwide license for the AMPAKINE technology for ADHD. Upon exercise, Cortex would have received a license fee, milestone payments based on successful clinical and commercial development, research support for additional AMPAKINE compounds and royalties on sales.

In May 2002, Shire made a business decision to abruptly terminate the Phase II study of CX516 in adult patients with ADHD. At the time of the decision to immediately stop all treatments, 72 patients out of a planned 110 patient study target had been enrolled. Only 45 patients had completed the 28-day course of treatment required by the study design. Because the study design was broken by the sudden cessation of all treatments and only 40% of the patients completed the full treatment plan, the data from the study could not be properly analyzed. In June 2002, Shire elected not to exercise its option for use of the AMPAKINE technology in ADHD. Cortex still believes that the potential for the use of AMPAKINE compounds as a treatment for ADHD exists and is seeking other partners to pursue this possibility.

Following Shire’s decision to forgo its option, Servier immediately declared CX516 its lead AMPAKINE compound in the field of MCI, Alzheimer’s disease and other neurodegenerative diseases in its territory, primarily Europe and Asia. Shire had previously held the first right of refusal to keep CX516 in ADHD.

Stroke

A stroke occurs when a blood clot blocks a blood vessel or artery, or when a blood vessel breaks and interrupts blood flow to the brain. When a stroke occurs, brain cells within the immediate area of damage usually die within minutes to a few hours. When brain cells die, control of functions such as speech, movement and memory may be lost.

A stroke can happen to anyone, although the risk increases significantly with age. According to the National Stroke Association, two-thirds of all strokes happen to people over the age of 65, with the risk doubling each decade past age 55.

Treatment of stroke victims represents a critical unmet need. The National Stroke Association estimates that there are nearly four million people in the U.S. who have survived a stroke and are living with the after-effects.

General recovery guidelines indicate that 35% of stroke survivors recover nearly completely, or with minor impairments. Of the remaining 65% of survivors, 40% suffer moderate to severe impairments, 10% require specialized care in a nursing home or other long-term care facility and 15% die shortly following the stroke.

Preclinical experiments conducted by Kevin Lee, Ph.D. at the University of Virginia and by two pharmaceutical companies have demonstrated that the AMPAKINE CX516 can be safely administered to animals under mimicked stroke-like conditions. Additionally, research at Cortex suggests that AMPAKINE compounds may be neuroprotective — AMPAKINE treatment may provide protection to at-risk neurons adjacent to the area of damage following a stroke.

AMPAKINE compounds also may improve post-stroke recovery. Nerve cells depend upon active stimulation or communication to maintain function. After a stroke, many neurons lose connections with other cells. Patients must try to recover function by engaging new pathways of nerve cell communication. AMPAKINE compounds, which enhance communication between nerve cells, may be ideal for the stroke recovery process.

In May 1999, Cortex received notice of a Phase I SBIR award of $100,000 from the National Institutes of Health to investigate the AMPAKINE technology as a potential new stroke therapy. Subsequently, in October 2000 Cortex received notice of a Phase II SBIR award of up to $1,074,000 to continue its research.

The goals of the research plan include determining if an AMPAKINE compound administered in advance can reduce damage to neurons in an animal model of stroke; and to determine if the compound reduces damage to the memory of the animals. An AMPAKINE compound will also be administered after the stroke to determine if there is an improved recovery of memory function. As of June 30, 2003, Cortex had received approximately $655,000 from this three-year grant award, with the term of the project extended for a one-year period. Research of the AMPAKINE technology as a treatment for stroke, beyond that funded by the SBIR grant, will depend upon the Company’s financial resources.

Fragile X and Autism

Fragile X is an inherited disorder that represents the most common cause of inherited mental retardation. The disorder affects approximately 60,000 to 80,000 patients in the U.S. alone. Symptoms of fragile X syndrome include mental impairment ranging from learning disabilities to mental retardation, attention deficit and hyperactivity, anxiety and unstable mood and autistic-like behaviors.

Table of Contents

Males are typically more severely affected by fragile X syndrome than females. Although most males with fragile X syndrome have mental retardation, only one-third to one-half of females with the disorder have significant intellectual impairment; the rest have either normal intelligence or learning disabilities. Emotional and behavioral problems are common in both sexes. There are no current therapeutic treatments for the disorder, although medications are used to treat some symptoms.

Autism is a complex developmental disability that typically appears during the first three years of life. The result of a neurological disorder that affects the functioning of the brain, autism and its associated behaviors have been estimated to occur in as many as 2 to 6 in 1,000 individuals. The disability is four times more prevalent in males than in females.

Autism impacts the normal development of the brain in the areas of social interaction and communication skills. Children and adults with autism typically have difficulties in verbal and nonverbal communication, social interactions, and leisure or play activities. Persons with autism may exhibit repeated body movements, unusual responses to people or attachments to objects, and resistance to changes in routines. Individuals also may experience heightened sensitivities of sight, hearing, touch, smell and taste. There are currently no approved therapeutic treatments for autism, although early behavioral intervention dramatically improves outcome.

Recent scientific research has led to an improved understanding of fragile X syndrome and autism. A number of scientists have suggested that the use of a drug to enhance glutamate transmission may be beneficial. AMPAKINE compounds, which have demonstrated enhanced glutamate transmission, may therefore serve as potential new therapeutics.

Imaging studies demonstrate that areas of the brain that are extremely rich in glutamate transmission are less active in autistic patients. Molecular studies suggest that although genes involved in the AMPA-type glutamate receptor are more active in autistic patients, the density of AMPA-type glutamate receptors is decreased. Taken together, these facts suggest that enhancing AMPA receptor activity may be beneficial in autistic patients.

The scientific logic for using an AMPA receptor modulator in fragile X is more complex but equally compelling. The fragile X genetic defect results in the reduction or absence of an important protein, FMRP. FMRP is thought to play an important role in allowing normal levels of AMPA receptor proteins to be made. Increasing the activity of AMPA receptors with an AMPAKINE may overcome the reduced number of AMPA receptors produced by the reduced level of FMRP protein.

In April 2002, Cortex announced that it is collaborating with several research organizations to conduct a Phase II clinical study to evaluate the AMPAKINE CX516 as a potential treatment for fragile X syndrome and autism. The study design is a randomized double-blind, placebo controlled trial with four weeks of treatment. Outcome measures will include testing in attention and executive function, spatial and verbal/auditory memory, language domain and behavior domain. Patient enrollment began in May 2002 and is anticipated to continue over a two-year period.

The FRAXA Research Foundation is providing funding for the trial at Rush-Presbyterian-St. Luke’s Medical Center in Chicago, and Cortex is providing study medication (CX516 and placebo capsules). The Child and Adolescent Psychiatry Department at the University of Chicago will also participate in the study along with The Mind Institute at the University of Davis Medical Center.

Narcolepsy and Other Sleep Disorders

Narcolepsy represents a disabling neurological disorder involving excessive daytime sleepiness and periodic irresistible sleep attacks of sudden onset and brief duration. The number and severity of symptoms vary widely among individuals with the disorder, with symptoms generally beginning between the ages of 15 and 30. Prevalence of narcolepsy in the U.S. is under 200,000. The disorder is known to occur in equal frequency in both sexes and to affect all ethnic populations.

According to the National Institute of Neurological Disorders and Stroke (“NINDS”), patients with narcolepsy experience sleep attacks that can last for up to 30 minutes, regardless of the amount or quality of the prior night’s sleep. The sleep attacks may occur at work, social events, while eating, talking and driving, and in other similarly inappropriate circumstances.

There is currently no cure for the disorder, although the symptoms may be controlled with behavioral and medical therapy. The therapeutic focus is to promote and enhance wakefulness and counteract excessive daytime sleepiness. The Company believes that AMPAKINE compounds may be useful in treating day time sleepiness, which is a key treatment for individuals with narcolepsy.

Sleep disorders represent a broad range of illnesses arising from many causes, including abnormalities in physiological functions during sleep, abnormalities of the biological clock and sleep disturbances that are induced by factors outside of the sleep process.

According to the National Sleep Foundation, over the past century, society has reduced its average asleep time by 20 percent and, in the past 25 years, added a month to its average annual work/commute time. When the body is deprived of the sleep that it needs, the ability to concentrate or perform even simple tasks declines, and productivity suffers.

An internal biological clock in the brain regulates our sleep needs and patterns. Almost everyone’s clock is set for sleep at night, especially in the early morning hours between midnight and dawn. When our lives force us to work against our biological clocks, sleep problems are unavoidable.

The National Sleep Foundation estimates that 20 percent of American employees work non-traditional schedules. For these workers, getting enough sleep is a common problem.

Together with the Defense Advanced Research Projects Agency (“DARPA”) of the U.S. Defense Department, the Company has initiated a clinical trial in young healthy adults who have been deprived of sleep for 36 hours. The single-dose, placebo-controlled trial will measure the impact of the AMPAKINE CX516 on the speed and accuracy of subjects’ response to selected tasks. The study is being conducted at the Medical University of South Carolina and is anticipated to be concluded by the beginning of the fourth quarter of calendar year 2003. Successful treatment of the effects from sleep deprivation may lead to successful treatment of excessive daytime sleepiness. Based on the results of this study, expansion to the use of AMPAKINE compounds to the treatment of narcolepsy may be possible. Narcolepsy represents an Orphan Drug indication that would reduce both the cost and time to market for a potential therapeutic agent from Cortex.

Manufacturing

Cortex has no experience or capability to either manufacture bulk quantities of the new compounds that it develops, or to produce finished dosage forms of the compounds, such as tablets or capsules. Cortex relies, and presently intends to rely, on the manufacturing and quality control expertise of contract manufacturing organizations or current and prospective corporate partners. There is no assurance that the Company will be able to enter into manufacturing arrangements to produce bulk quantities of its compounds on favorable financial terms. There is however, substantial availability of

13

Table of Contents

dosage form manufacturing capability in the U.S. pharmaceutical industry that the Company believes that it can readily access.

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 for indications such as Alzheimer’s disease and schizophrenia. The Company will therefore continue to seek commercial development arrangements with other pharmaceutical companies for its proposed products for those indications that require significant sales forces to effectively market. In entering into such arrangements, the Company may seek to retain the right to promote or co-promote products for certain indications in North America. The Company’s worldwide licensing agreement with Organon (see Note 5 of Notes to Financial Statements) does not provide Cortex with co-promotional rights. With respect to Orphan Drugs, the Company may distribute and market such products directly. There is no assurance that the Company will be able to enter into marketing arrangements in connection with its other licensing activities, or that marketing rights will lead to greater revenues for the Company.

Technology Rights

In 1993, Cortex entered an agreement with the Regents of the University of California, under which Cortex secured exclusive commercial rights to AMPA-receptor modulating technology and compounds (the AMPAKINE technology) for the treatment of deficits of memory and cognition. The relationship later was expanded to include additional agreements for other indications. The Company paid an initial license fee and is obligated to make additional payments, including license maintenance fees and patent expense reimbursements creditable against future royalties, over the course of initiating and conducting human clinical testing and obtaining regulatory approvals. When and if sales of licensed products commence, the Company will pay royalties on net sales. During the fiscal year ended June 30, 2003, Cortex amended the agreement with the Regents of the University of California to exclude the treatment of disease areas outside of the Central Nervous System that the Company would not have the resources nor the capability to develop in a timely manner.

Patents and Proprietary Rights

The Company is aggressively pursuing patent protection of its technologies. Cortex owns or has exclusive rights (within its areas of product development) to approximately 40 issued or allowed U.S. and foreign patents and has a number of additional U.S. patent applications and their international counterparts pending.

In 1998, Cortex received a United States patent that contained a broad claim for any AMPA-modulating compound to treat schizophrenia. Under the agreements with the Regents of the University of California (the “University”), Cortex has exclusive rights to AMPAKINE compounds for all applications covered by the University’s patent rights, other than endocrine modulation, and the treatment of sexual dysfunction in North and South America. Cortex’s rights are contingent upon it making certain minimum annual payments to the University, meeting certain milestones, and diligently seeking to commercialize the underlying technology.

14

Table of Contents

In April 1999, Cortex received a patent that covers the Company’s AMPAKINE compounds — as well as compounds made by others — for the treatment of memory and cognition. This patent allows Cortex and its licensees to exclude others in the United States from making and selling AMPA-receptor modulating compounds for the treatment of memory or dementia, including Alzheimer’s disease. The Company believes that the coverage also extends to psychiatric conditions with cognitive disturbances including depression, obsessive compulsive disorder, attention deficit disorder, and phobic disorders. Similar patents have issued to Cortex in Mexico, Australia and New Zealand. In April 2003, Cortex announced the allowance of a similar patent by the European Patent Office. These patents issued to the University of California and rights to the patents are licensed to Cortex.

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

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

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

Government Regulation

In order to test, produce and market human therapeutic products in the United States, mandatory procedures and safety standards established by the FDA must be satisfied. Obtaining FDA approval is a costly and time-consuming process. Cortex has initiated Phase I and early Phase II testing in the U.S. and Europe, primarily with the assistance of clinical collaborators and its corporate partners, Organon and Servier. Some clinical trials were and are performed in the U.S. under Notices of Claimed Investigational Exemption for a New Drug (“IND”) filed with the FDA by the Company’s clinical collaborators. Cortex filed an IND for the AMPAKINE CX516 in the name of the Company in the fall of 2000. It is Cortex’s intent that Organon, Servier or another pharmaceutical company partner or partners that the Company is seeking, will pursue other required regulatory approvals to conduct further clinical testing. Cortex intends to file other IND’s for additional compounds to facilitate the development of its Orphan Drug strategy.

Clinical trials are normally conducted in three phases. Phase I trials are concerned primarily with safety of the drug, involve fewer than 100 subjects, and may take from six months to over a year. Phase II trials normally involve a few hundred patients. Phase II trials are designed to demonstrate effectiveness and to determine optimal dosing in treating or diagnosing the disease or condition for which the drug is intended. Short-term side effects and risks in people whose health is impaired also may be examined. Phase III trials may involve up to several thousand patients who have the disease or condition for which

15

Table of Contents

the drug is intended, to approximate more closely the conditions of ordinary medical practice. Phase III trials also are designed to clarify the drug’s benefit-risk relationship, to uncover less common side effects and adverse reactions, and to generate information for proper labeling of the drug. The FDA receives reports on the progress of each phase of clinical testing, and may require the modification, suspension, or termination of clinical trials if an unwarranted risk is presented to patients. The FDA estimates that the clinical trial period of drug development can take up to ten years, and averages five years. With certain exceptions, once clinical testing is completed, the sponsor can submit a New Drug Application (“NDA”) for approval to market a drug. The FDA’s review of an NDA can also be lengthy.

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

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

Cortex plans to seek additional financing to support its development of selected AMPAKINE compounds for Orphan Drug indications. Without obtaining shareholder approval for such further issuance of securities, Cortex may be severely restricted in its overall development. The Company would be dependent upon its sub-licensees and would be unable to maintain its current core technical and management capabilities. Under such circumstances, the Company would be dependent upon entering into partnerships or other collaborative arrangements with third parties with the required resources to obtain the needed approvals. Along with its licensing agreements with Organon and Servier, Cortex intends to enter into license or other arrangements with other pharmaceutical companies under which those companies would conduct the required clinical trials and seek FDA approval for most or all of its proposed products. There is no assurance that Cortex will be able to enter into such arrangements on favorable terms, or at all, or that such arrangements will ultimately result in obtaining the necessary governmental approvals.

Competition

The pharmaceutical industry is characterized by rapidly evolving technology and intense competition. Many companies of all sizes, including both major pharmaceutical companies and specialized biotechnology companies, are engaged in activities similar to those of Cortex. A large number of drugs intended for the treatment of Alzheimer’s disease, MCI, schizophrenia, depression, ADHD and other neurological and psychiatric diseases and disorders are on the market or in the later stages of clinical testing. For example, approximately 15 drugs are in development in the U.S. for schizophrenia. In addition, over 25 drugs are under clinical investigation in the U.S. for the treatment of Alzheimer’s disease and approximately 10 drugs are under clinical investigation in the U.S. for the treatment of MCI. Some of the Company’s competitors have substantially greater financial and other resources and larger research and development staffs. Larger pharmaceutical company competitors also have significant experience in preclinical testing, human clinical trials and regulatory approval procedures.

In addition, colleges, universities, governmental agencies and other public and private research organizations will continue to conduct research. These institutions 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.

16

Table of Contents

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 those advances continue. Based on the technical qualifications, expertise and reputations of its Scientific Directors, consultants and other key scientists, the Company believes that its operating strategy to develop AMPAKINE compounds for the treatment of selected Orphan Drug indications and to out-license the technology to larger pharmaceutical companies for major chronic indications is appropriate.

Product Liability Insurance

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

Employees

As of June 30, 2003, Cortex had 20 full-time employees and one part-time employee and had engaged one part-time DVM-level and three part-time Ph.D.-level scientific consultants. Of the 20 full-time employees, 14 were engaged in research and development, of which 8 were Ph.D.-level or equivalent, and 6 were engaged in management and administrative support. The Company also sponsors a substantial amount of research in academic laboratories, primarily at the University of California, Irvine.

Risk Factors

In addition to the other matters set forth in this Annual Report on Form 10-K, our continuing operations and the price of our common stock are subject to the following risks:

If we cannot raise capital on acceptable terms, we may need to significantly curtail our operations.

Without further infusions of capital, we anticipate that we have sufficient funds and committed sources of funding from Servier to maintain our operations into fiscal year 2005. We will require additional funds to continue our operations beyond that time. We cannot say with any amount of certainty that we will be able to obtain the additional needed funds on reasonable terms, or at all. We currently do not have sufficient authorized shares of common stock to undertake any significant common stock financing and we will need to obtain stockholder approval to authorize more shares of common stock. If we do not obtain such approval we will not be able to raise additional funds by the sale of common stock, or securities convertible into common stock. If we obtain such approval and raise additional funds by issuing more of our securities, stockholders at the time of issuance will experience a dilution to the value of their securities. Management believes that our ability to obtain sufficient funds for further development of the AMPAKINE technology is critical to our progress.

Additional funds may result from milestone payments related to our agreements with Organon and Servier, although there is no assurance that we will receive milestone payments from Organon or Servier within the desired time frame, or at all.

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

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

A significant percentage of our revenues come from our agreements with Organon and Servier, and if either or both agreements were terminated, our financial condition could be seriously impaired.

We are dependent on future payments from Organon and Servier to continue the development and commercialization of our AMPAKINE technology. Under the agreement with Organon that we entered in January 1999, the collaborative research phase ended in January 2001. Organon has primary responsibility for developing and commercializing AMPAKINE compounds for use in the treatment of schizophrenia and depression. Through June 30, 2003 we have received $6,000,000 in upfront and milestone payments and approximately $6,000,000 in research support payments. The agreement also includes milestone payments, plus royalty payments on a worldwide basis. We anticipate that we may trigger an additional milestone during the fiscal year ending June 30, 2004, although there is no assurance that such milestone will occur. Under the terms of the agreement, Organon has the right to terminate the agreement upon four-months’ prior notice. If Organon were to discontinue its financial support, we might not be able to continue the development of our AMPAKINE technology as a potential treatment for patients with schizophrenia and depression.

18

Table of Contents

Under the agreement with Servier that we entered into in October 2000 and amended in October 2002, we share the research efforts. Servier has primary responsibility for developing and commercializing AMPAKINE compounds for use in the treatment of memory impairment associated with aging, and of neurodegenerative diseases such as Alzheimer’s disease. Through June 30, 2003, we have received an up-front payment of $5,000,000 and research support payments of approximately $7,800,000. Under the October 2000 agreement, we currently receive approximately $2,000,000 per year (subject to us providing agreed-upon levels of research) and Servier is obligated to continue this level of support into early December 2003. Under the October 2002 amendment, we currently receive an additional $2,000,000 per year, which Servier is obligated to continue into early October 2004. The agreement includes milestone payments, plus royalty payments on sales in licensed territories. We do not anticipate that any milestone payments from Servier will occur during the fiscal year ending June 30, 2004. Under the terms of the agreement, Servier has the right to terminate the agreement in the case of a merger or acquisition involving us and a third party. Servier also has the right to terminate the agreement upon six-months’ prior notice at any time after the research phase of the collaboration. In addition, Servier has the right to terminate the related research and development in the event that we materially breach the agreement. If Servier were to discontinue its financial support, we might not be able to continue the development of our AMPAKINE technology for the applications licensed to Servier and our financial condition could be seriously impaired.

We have a history of net losses; we expect to continue to incur net losses and we may never achieve or maintain profitability.

Since our formation on February 10, 1987 through June 30, 2003, we have generated only modest operating revenues and we have incurred net losses approximating $42,057,000. As of June 30, 2003, we had an accumulated deficit of approximately $44,089,000. We have not generated any revenue from product sales to date, and it is possible that we will never generate revenues from product sales in the future. Even if we do achieve significant revenues from product sales, we expect to incur significant operating losses over the next several years. It is possible that we will never achieve profitable operations. We will require substantial additional funds to advance our research and development programs, particularly if we decide to independently conduct later-stage clinical testing and apply for regulatory approval of any of our proposed products.

We may not be able to enter into the strategic alliances necessary to fully develop and commercialize our products and technologies, and we will be dependent on our corporate partners if we do.

In addition to our agreements with Organon and Servier, we are seeking other pharmaceutical company partners to develop other major indications for the AMPAKINE compounds. In connection with our efforts to secure corporate partners, we will seek to retain certain co-promotional rights to our proposed products. These co-promotional rights will allow us to market our products to selected medical specialists while our corporate partner markets our products to the general medical market. We cannot assure you that we will be able to enter into any partnering arrangements on this or any other basis. In addition, we cannot assure you that we, Organon, Servier or our prospective corporate partners, can successfully introduce our proposed products. We also face the risks that our products will be rejected by patients, health care providers or insurance companies, or that our products cannot be manufactured and marketed at prices that would permit us to operate profitably. Additionally, we plan to develop certain compounds for selected smaller indications referred to previously as Orphan Drugs. We may or may not be successful in getting the appropriate positive clinical results and obtaining approval to market our compounds for these indications in the U.S.

We are at an early stage of development and we may not be able to successfully develop and commercialize our products and technologies.

The development of AMPAKINE products is subject to the risks of failure commonly experienced in the development of products based upon innovative technologies and the expense and difficulty of

19

Table of Contents

obtaining approvals from regulatory agencies. All of our proposed products are in the preclinical or early clinical stage of development and will require significant additional funding for research, development and clinical testing before we are able to submit them to any of the regulatory agencies for clearances for commercial use. We cannot assure you that we will be able to complete successfully any of our research and development activities. Even if we do complete them, we may not be able to market successfully any of the products or be able to obtain the necessary regulatory approvals or assure that healthcare providers and payors will accept our products. We also face the risk that any or all of our products will not work as intended or that they will be unsafe, or that, even if they do work and are safe, that our products will be uneconomical to manufacture and market on a large scale. Due to the extended testing and regulatory review process required before we can obtain marketing clearance, we do not expect to be able to commercialize any therapeutic drug for at least five years, either directly or through our corporate partners or licensees.

Our products rely on licenses from the Regents of the University of California, and if we lose access to these technologies, our business would be substantially impaired.

Under our agreements with the Regents of the University of California, we have exclusive rights to AMPAKINE compounds for all applications for which the University has patent rights, other than endocrine modulation, and the treatment of sexual dysfunction in North and South America.

Our rights to the AMPAKINE compounds are secured by patents or patent applications owned wholly by the University or by the University as a co-owner with us. Our existing agreements require us to make certain minimum annual payments, meet certain milestones and diligently seek to commercialize the underlying technology. Our failure to meet any of these requirements could allow the University to terminate that particular agreement.

If we fail to secure adequate intellectual property protection, it could significantly harm our financial results and ability to compete.

Our success will depend, in part, on our ability to get patent protection for our products and processes in the United States and elsewhere. We have filed and intend to continue to file patent applications as we need them. However, additional patents that may issue from any of these applications may not be sufficiently broad to protect our technology. Also, any patents issued to us or licensed by us may be challenged by others, and if successful, such challenges may diminish our rights.

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

We also rely on trade secrets and confidential information that we try to protect by entering into confidentiality agreements with other parties. Those confidentiality agreements may be breached, and our remedies may be insufficient to protect the confidential information. Further, our competitors may independently learn our trade secrets or develop similar or superior technologies. To the extent that our consultants, key employees or others apply technological information independently developed by them or by others to our projects, disputes may arise regarding the proprietary rights to such information. We cannot assure you that such disputes will be resolved in our favor.

There is a large number of shares of common stock that may be sold, which may depress the market price of our stock.

Upon effectiveness of the registration statement that we are required to file in connection with our August 2003 private placement, an additional 3,333,334 shares will become freely tradable without restriction. If all outstanding warrants and options are exercised prior to their expiration, approximately 7.3 million additional shares of common stock could become freely tradable without restriction. Sales of

20

Table of Contents

substantial amounts of common stock in the public market could adversely affect the prevailing market price of our common stock.

We face intense competition that could result in products that are superior to the products that we are developing.

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

We may be unable to recruit and retain our senior management and other key technical personnel on whom we are dependent.

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

If we are unable to maintain our relationships with academic consultants and the University of California, Irvine, our business could suffer.

We depend upon our relationships with academic consultants, particularly Dr. Gary S. Lynch of the University of California, Irvine. Dr. Lynch plays a role in guiding our research. In addition, we sponsor preclinical research in Dr. Lynch’s laboratories at the University of California, Irvine that is part of our product development and corporate partnering profile. If our relationship with Dr. Lynch or the University of California, Irvine, is disrupted, our AMPA- receptor research program could be adversely affected. Our agreements with Dr. Lynch and our other consultants are generally terminable by the consultant on short notice.

The regulatory approval process is expensive, time consuming, uncertain and may prevent us from obtaining required approvals for the commercialization of some of our products.

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

Our stock price may be volatile and our common stock could decline in value.

The market price of securities of life sciences companies in general has been very unpredictable. The following factors, in addition to factors that affect that market generally, could significantly impact our business, and the market price of our common stock could fall:

Our charter document and shareholder rights plan may discourage companies from acquiring us and offering our stockholders a premium for their shares, and could adversely affect the market price of our common stock.

Certain provisions of our certificate of incorporation could make it more difficult for a third party to acquire control of our business, even if such change in control would be beneficial to our stockholders. Our certificate of incorporation allows our Board of Directors to issue up to 549,500 shares of preferred stock without stockholder approval. Pursuant to this authority, in February 2002 our Board of Directors adopted a shareholder rights plan and declared a dividend of a right to purchase one one-thousandth of a share of preferred stock for each outstanding share of our common stock. The shareholder rights plan may have the effect of delaying, deferring or preventing a change in control of our business. This may discourage bids for our common stock at a premium over the market price of the common stock and may adversely affect the market price of our common stock.

We may fail to continue to meet the listing standards for the American Stock Exchange and, in the event that our common stock is delisted from such exchange, the liquidity of our common stock is likely to be impaired and the market price of our shares could be adversely affected.

The listing standards for the American Stock Exchange include a stockholders’ equity and market capitalization test. The Exchange also monitors the financial condition and stability of listed companies. As of June 30, 2003, we had a stockholders’ deficit of approximately $1,400,000, which does not meet the current listing standards. With the estimated net proceeds from the private placement of the Company’s common stock in August 2003, the Company believes that it will meet the current listing standards.

In the event that we fail to satisfy the listing standards on a continuous basis, the Exchange will contact us regarding our status. Within 30 days of such contact, we can provide the Exchange with our plan of action to bring us into compliance with the listing standards within 18 months of the contact by the Exchange. If we do not provide a plan or if the Exchange does not accept our plan, delisting procedures will commence. If our plan is accepted, the Exchange will review our compliance with the plan on a quarterly basis. If we do not show progress consistent with our plan, delisting procedures may begin. If our common stock is removed from listing on the Exchange, the liquidity of our common stock is likely to be impaired and the trading price reduced.

Changes in laws, regulations and financial accounting standards may affect our reported results of operations.

The recently enacted Sarbanes-Oxley Act of 2002 and related regulations may result in changes in accounting standards or accepted practices within our industry and could add significant new costs to being a public company. New pronouncements and varying interpretations of pronouncements have occurred in the past and are likely to occur in the future as a result of recent Congressional and regulatory actions. New laws, regulations, and accounting standards, as well as potential changes to currently accepted accounting practices in the technology industry, including the expensing of stock options, could adversely affect our reported financial results and negatively impact our stock price. Additional unanticipated expenses incurred to comply with new requirements could also negatively impact our results of operations.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the audited financial statements and notes related thereto appearing elsewhere herein.

Critical Accounting Policies and Management Estimates

The Securities and Exchange Commission defines critical accounting policies as those that are, in management’s view, most important to the portrayal of the company’s financial condition and results of operations and most demanding of their judgment. Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities.

We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. This process forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition

Our revenue recognition policies are in accordance with the Securities and Exchange Commission’s Staff Accounting Bulletin No. 101, “Revenue Recognition” (“SAB 101”). SAB 101 provides guidance in applying accounting principles generally accepted in the United States to revenue recognition issues, and specifically addresses revenue recognition for up-front, nonrefundable fees received in connection with research collaboration arrangements.

In accordance with SAB 101, revenues from up-front fees from our collaborators are deferred and recorded over the term that we provide ongoing services. Similarly, research support payments are recorded as revenue as we perform the research under the related agreements. We record grant revenues as we incur expenses related to the grant projects. All amounts received under collaborative research agreements or research grants are nonrefundable, regardless of the success of the underlying research.

Revenues from milestone payments are recognized when earned, as evidenced by written acknowledgment from our collaborator, provided that (i) the milestone event is substantive and its achievement was not reasonably assured at the inception of the agreement, and (ii) our performance obligations after the milestone achievement will continue to be funded by our collaborator at a comparable level to that before the milestone achievement. If both of these criteria are not met, the milestone payment is recognized over the remaining minimum period of our performance obligations under the agreement.

In November 2002, the Emerging Issues Task Force (“EITF”) of the Financial Accounting Standards Board reached consensus on Issue 00-21. EITF Issue 00-21 addresses the accounting for arrangements that may involve the delivery or performance of multiple products, services and/or rights to use assets. Specifically, Issue 00-21 requires the recognition of revenue from milestone payments over the remaining minimum period of performance obligations. As required, we will apply the principles of Issue 00-21 to multiple element agreements that we may enter into after July 1, 2003.

The above listing is not intended to be a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States, with no need for management’s judgment in their application. There are also areas in which management’s judgment in selecting any available alternative would not

produce a materially different result. See our audited financial statements and notes thereto which begin on page F-1 of this Annual Report on Form 10-K, which contain accounting policies and other disclosures required by accounting principles generally accepted in the United States.

Results of Operations

General

In October 2000, the Company entered into a research collaboration and an exclusive license agreement with Les Laboratoires Servier (“Servier”). The agreement will allow Servier to develop and commercialize the Company’s AMPAKINE^® technology for the treatment of declines in cognitive performance associated with aging and neurodegenerative diseases. The indications covered include, but are not limited to, Alzheimer’s disease, mild cognitive impairment, sexual dysfunction, and the dementia associated with multiple sclerosis and Amyotrophic Lateral Sclerosis.

The agreement with Servier includes a nonrefundable up-front fee of $5,000,000 and research support payments of $2,025,000 per year for three years (subject to Cortex providing agreed-upon levels of research personnel). The amount of research support is subject to annual adjustment based upon the increase in the U.S. Department of Labor’s Consumer Price Index. Currently, Cortex receives research support of approximately $2,115,000 per year. The agreement also includes potential milestone payments, plus royalty payments on sales in licensed territories.

In October 2002, Servier agreed to provide Cortex with $4,000,000 of additional research support, in exchange for rights to our AMPAKINE compounds for the potential treatment of anxiety disorders, in Servier’s licensed territories. The $4,000,000 will be paid in quarterly installments of $500,000 over a two-year period, beginning in October 2002.

In January 1999, the Company entered into a research collaboration and exclusive worldwide license agreement with NV Organon (“Organon”), a pharmaceutical business unit of Akzo Nobel. The agreement will allow Organon to develop and commercialize the Company’s proprietary AMPAKINE technology for the treatment of schizophrenia and depression. In connection with the agreement, the Company received a $2,000,000 up-front licensing payment and research support payments of approximately $3,000,000 per year for two years.

The agreement with Organon also includes milestone payments based upon clinical development, plus royalty payments on worldwide sales. Cortex achieved its first milestone under the agreement in May 2000, when Organon selected a candidate compound to pursue in Phase I clinical testing as a treatment for schizophrenia. Achieving this milestone triggered a $2,000,000 payment from Organon, which Cortex recorded as revenue upon achievement.

Cortex achieved its second milestone under the agreement in September 2001, when Organon elected to continue development of the selected compound in Phase II clinical testing. Achieving the second milestone triggered another $2,000,000 payment from Organon, with the related revenue recorded upon achievement of the milestone.

From inception (February 10, 1987) through June 30, 2003, the Company sustained losses aggregating $42,057,000. Due to projected fluctuations in funding, continuing losses are likely over the next several years, as the Company’s ongoing operating expenses will only be offset, if at all, by research support payments and possible milestone payments from its research collaborations with Servier and Organon, or under planned strategic alliances that the Company is seeking with other pharmaceutical companies for the clinical development, manufacturing and marketing of its products. The nature and timing of payments to Cortex under the Servier and Organon agreements or other planned strategic alliances, if and when entered into, are likely to significantly affect the Company’s operations and financing activities and

27

Table of Contents

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

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

Fiscal Years ended June 30, 2003 and 2002

For the year ended June 30, 2003, the Company’s net loss of $1,175,000 compared to a net loss of $983,000 for the prior year, with the increased net loss primarily attributable to the timing of revenues from the Company’s collaborative agreements.

Revenues for the year ended June 30, 2003 decreased from $6,433,000 to $5,232,000, or by 19% compared to the prior year, with a net increase in research and licensing revenue from the agreement with Servier of $1,036,000, but a decrease in revenues from the agreement with Organon of $2,000,000. For the year ended June 30, 2003, revenues included $1,500,000 related to the amendment to the Servier agreement signed in October 2002. That amendment granted Servier rights to the Company’s AMPAKINE technology in the field of anxiety disorders, in Servier’s licensed territories. In exchange for those rights, Cortex will receive $4,000,000 of research funding from Servier, paid as $500,000 per quarter over a two-year period.

With the amendment to the agreement, Cortex extended the period that it amortizes revenues from Servier’s earlier up-front fee. Under the original October 2000 agreement, Cortex received a $5,000,000 licensing fee from Servier, which Cortex was recording as revenue over that agreement’s three-year collaborative research phase. After amending the agreement in October 2002, Cortex began amortizing the remaining unearned licensing revenues over the two-year period of the extended research support. Compared to the prior year, licensing revenues for the year ended June 30, 2003 decreased by $509,000 as a result of this change.

Revenues for fiscal year 2002 included a $2,000,000 milestone payment from the agreement with Organon, the Company’s other collaborative partner. Organon triggered this milestone in September 2001 when it elected to continue its development of an AMPAKINE compound by entering Phase II studies for schizophrenia. Cortex recorded the revenue from this milestone upon achievement as the Company has no ongoing obligations under the related agreement.

Research and development expenses for the year ended June 30, 2003 decreased to $3,801,000, or by 25% compared to the prior fiscal year. The decrease resulted from charges incurred in the prior year for the Phase II clinical study in MCI being conducted with Servier. In connection with the MCI study, in January 2002 the Company sponsored a meeting of the clinical investigators participating in the trial. Nearly all other costs for this study were borne by Servier. The decrease for the current year also reflected decreased personnel-related expenses of $407,000 from comparatively lower staffing levels and a resultant decrease of $100,000 in spending for animals and laboratory supplies. In addition, prior year research and development expenses included technology access payments related to the Organon milestone. Cortex licenses the AMPAKINE technology from the University of California. Under the related agreement, Cortex is required to remit a portion of certain remuneration received in connection with sublicensing agreements. In September 2001, when Cortex achieved its milestone under its agreement with Organon, a technology access payment to the University of California became due.

General and administrative expenses for the year ended June 30, 2003 increased to $2,620,000, or by 7% compared to the prior year, primarily due to severance costs to the Company’s former President and Chief Executive Officer.

28

Table of Contents

Net interest income for the year ended June 30, 2003 decreased to $15,000, or by 80% compared to the prior year, due to a decrease in cash available for investing.

Fiscal Years ended June 30, 2002 and 2001

For the year ended June 30, 2002, the Company’s net loss of $983,000 compared to a net loss of $2,673,000 for the prior year. The difference primarily represented increased research and licensing revenues.

Revenues for the year ended June 30, 2002 increased from $4,443,000 to $6,433,000, or by 45% compared to the prior year and included a full year of research and licensing revenues from the October 2000 agreement with Servier. Under the related agreement, Cortex receives approximately $2,000,000 of research support per year for a minimum of three years (subject to Cortex providing agreed-upon levels of research), beginning in December 2000. In addition, Cortex received an up-front payment of $5,000,000 from Servier, which it is recording as revenue ratably over the agreement’s collaborative research phase.

Revenues for the year ended June 30, 2002 also included a $2,000,000 milestone payment from the agreement with Organon, triggered when Organon elected to continue development of an AMPAKINE compound by entering Phase II clinical studies for schizophrenia. For the year ended June 30, 2001, revenues from the Organon agreement included the remaining scheduled research support of $1,470,000. For the same period ending June 30, 2001, Cortex recorded $530,000 of licensing revenues from the Organon agreement, in accordance with SAB 101, as explained more fully below.

Research and development expenses increased to $5,043,000, or by 14%, during the year ended June 30, 2002 compared to the prior year. The increase included expenses for a meeting of Principal Investigators for the Phase II clinical study of the AMPAKINE CX516 in patients with mild cognitive impairment. The cross-national study, conducted in collaboration with Servier, commenced enrollment in March 2002. Servier has agreed to support the bulk of the costs for this study.

Research and development expenses for the year ended June 30, 2002 also included technology access payments related to the Organon milestone achieved in September 2001, as explained more fully in the comparison of the fiscal years ending June 30, 2003 and June 30, 2002, above.

General and administrative expenses of $2,444,000 for the year ended June 30, 2002 were materially consistent with those from the prior year.

For the year ended June 30, 2001, the Company recorded a charge of $530,000 to reflect the cumulative effect of a change in accounting principle related to the required adoption of SAB 101. Issued by the Securities and Exchange Commission, SAB 101 required the Company to change its accounting method for the up-front payment received from the agreement with Organon in 1999.

Instead of recording the revenue from the Organon up-front payment when it was received, under SAB 101 the Company restated the revenue ratably over the agreement’s two-year contract period. With the recorded cumulative effect of the change in accounting principle of $530,000, restating revenues by $530,000 had no impact on the net loss or net loss per share for the year ended June 30, 2001. Results for years prior to the year ended June 30, 2001 were not restated.

Liquidity and Capital Resources

Under the agreement signed with Servier in October 2000 and amended in October 2002, to date Cortex has received research and licensing payments of $12,814,000. Of this amount, Cortex received $4,107,000 during the year ended June 30, 2003. The October 2000 agreement provides research support of approximately $2,000,000 per year for three years ending in early December 2003, subject to annual

29

Table of Contents

adjustment based on the U.S. Department of Labor’s Consumer Price Index. Beginning in October 2002, Servier has agreed to provide an additional $4,000,000 of research support to Cortex, to be paid in quarterly installments of $500,000 over a two-year period. The agreement also includes milestone payments based upon successful clinical development and royalties on sales in licensed territories.

Research and licensing payments received in connection with the agreement with Organon totaled $11,880,000 through June 30, 2003. Of this amount, Cortex received $2,000,000 during the year ended June 30, 2002, representing the second milestone from the Organon agreement. The milestone was triggered in September 2001, when Organon elected to continue development of an AMPAKINE compound by entering Phase II clinical testing. Under the terms of the agreement, Cortex may receive additional milestone payments based on clinical development of the licensed technology and ultimately, royalties on worldwide sales.

In October 2000, Cortex received notice of a Phase II Small Business Innovative Research (“SBIR”) award from the National Institutes of Health. The award, as extended, will provide up to $1,074,000 over a four-year period and will partially offset the Company’s expenses in researching its AMPAKINE compounds as a potential new therapy for stroke. As of June 30, 2003, Cortex had received approximately $657,000 related to this grant award.

In September 2001, the Company received notice of a second Phase II SBIR award from the National Institutes of Health. This award, as extended, will provide up to $770,000 over a three-year period, which will allow Cortex to follow-up on previously reported studies of the AMPAKINE CX516 as a combination therapy for schizophrenia. Earlier tests were encouraging, with AMPAKINE-treated patients showing improvement in a number of clinical and neurocognitive scores. As of June 30, 2003, Cortex had received approximately $500,000 from this grant award.

In August 2003, the Company completed a private placement to 22 accredited investors of an aggregate of 3,333,334 shares of its common stock at $1.50 per share and five-year warrants to purchase up to an additional aggregate of 3,333,334 shares at an exercise price of $2.55 per share. The Company received approximately $4,500,000 in net proceeds from the private placement. The warrants are subject to a call right in favor of the Company to the extent that the closing price of the Company’s common stock exceeds $6.00 per share for any thirteen consecutive trading day period following the second anniversary of the date that the registration statement to be filed pursuant to the terms of the private placement is first declared effective by the Securities and Exchange Commission. If the warrants are fully exercised, of which there can be no assurance, these warrants would provide approximately $8,500,000 of additional capital.

Cash Proceeds

Prior to the Company’s private placement of its common stock, as of June 30, 2003 the Company had cash and cash equivalents totaling $1,125,000 and a working capital deficit of $1,505,000. As of June 30, 2002, the Company had cash and cash equivalents of $1,849,000 and a working capital deficit of $349,000. The decrease in cash as of June 30, 2003 reflected amounts required to fund operations.

For both periods, working capital included unearned revenue relating to the Company’s $5,000,000 nonrefundable, up-front payment from the October 2000 agreement with Servier. In accordance with SAB 101, the Company is recording the revenue related to the up-front payment ratably over the agreement’s collaborative research phase that ends, as extended in October 2004. Current liabilities as of June 30, 2003 and 2002 included $988,000 and $1,667,000, respectively, of unearned revenues from the non-refundable Servier up-front fee.

In addition, as of June 30, 2003 and 2002, unearned revenues included $1,029,000 and $520,000, respectively, for quarterly research support from Servier, paid in advance. The increase in these unearned

30

Table of Contents

revenues as of June 30, 2003 reflects $500,000 of additional research support under the amendment to the Servier agreement in October 2002.

Current liabilities as of June 30, 2003 and June 30, 2002 also included approximately $270,000 for the advance from the Institute for the Study of Aging (the “Institute”). This advance is being utilized to offset the Company’s limited expenses related to the cross national Phase II study in MCI being conducted with Servier. According to the agreed-upon terms, repayment of the advance shall be forgiven unless the Company enters Phase III clinical testing for Alzheimer’s disease. In the event that the Company enters such clinical trials with one of its AMPAKINE compounds, the Company believes that sufficient resources would become available under its partnering agreements to permit repayment of the advance.

Commitments

The Company leases approximately 32,000 square feet of research laboratory, office and expansion space under an operating lease that expires May 31, 2004. The commitments under the lease agreement for the years ending June 30, 2004 are $276,000. The Company is evaluating whether to seek to renew its current lease agreement or to pursue other leasing opportunities. From inception (February 10, 1987) through June 30, 2003, expenditures for furniture, equipment and leasehold improvements aggregated $2,611,000.

The Company is committed to $628,000 for sponsored research and other remuneration to academic institutions, all of which is payable over the next 12 months. As of June 30, 2003, the Company was committed to severance payments to its former Chief Executive Officer in the aggregate amount of $34,000, which payments were made in semi-monthly installments through mid-August 2003.

Together with its corporate partner, Servier, the Company is conducting a cross-national clinical study with the AMPAKINE CX516 in patients with mild cognitive impairment (MCI). Enrollment in the trial began in March 2002 and concluded in June 2003. Preliminary results are expected in the fall of 2003. Servier has agreed to incur the bulk of the related costs for the study. Remaining Cortex commitments for Phase I/IIa clinical studies on the AMPAKINE compounds are not significant.

In June 2000, the Company received $247,300 from the Institute, which will partially offset the Company’s costs for the testing in patients with MCI. Given that Cortex must use the funding from the Institute solely for clinical trials, the Company has recorded the amounts received as restricted cash in its balance sheet. Provided that Cortex complies with the conditions of the funding agreement, including the restricted use of the amounts received, repayment of the advance shall not be required unless Cortex enters an AMPAKINE compound into Phase III clinical trials for Alzheimer’s disease. Upon such potential clinical trials, repayment would include interest computed at a rate equal to one-half of the prime lending rate. In lieu of cash, in the event of repayment the Institute may elect to receive the balance of outstanding principal and accrued interest as shares of Cortex common stock. The conversion price for such form of repayment shall initially equal $4.50 per share, subject to adjustment under certain circumstances.

Staffing

As of June 30, 2003, Cortex had 21 employees. Neither significant investments in plant or equipment nor increases to staffing levels are contemplated under current spending plans for the upcoming fiscal year.

Outlook

Cortex anticipates that its cash and cash equivalents, scheduled research support payments from its agreements with Servier — and the approximately $4,500,000 net proceeds from the August 2003 private placement of the Company’s common stock — will be sufficient to satisfy the Company’s capital requirements into fiscal year 2005. Additional funds will be required to continue operations beyond that time. Cortex may receive additional milestone payments from the Organon and Servier agreements, but

31

Table of Contents

there is no assurance that the Company will receive such milestone payments within the desired timeframe, or at all. See “Risk Factors — If we cannot raise capital on acceptable terms, we may need to significantly curtail our operations.”

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

Because there is no assurance that the Company will secure additional corporate partnerships, the Company may raise additional capital through the sale of debt or equity securities. There is no assurance that funds will be available on favorable terms, or at all. If equity securities are issued to raise additional funds, dilution to existing stockholders may result.

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

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to certain market risks associated with interest rate fluctuations on its marketable securities and borrowing arrangement. All investments in marketable securities are entered into for purposes other than trading. The Company is not subject to risks from currency rate fluctuations as it does not typically conduct transactions in foreign currencies. In addition, the Company does not utilize hedging contracts or similar instruments.

The Company’s exposure to interest rate risk arises from financial instruments entered into in the normal course of business. Certain of the Company’s financial instruments are fixed rate, short-term investments in government and corporate notes and bonds, which are available for sale (and have been marked to market in the accompanying financial statements). Changes in interest rates generally affect the fair value of the investments, however, because these financial instruments are considered “available for sale,” all such changes are reflected in the financial statements in the period affected. The Company manages interest rate risk on its investment portfolio by matching scheduled investment maturities with its cash requirements. Due to the timing of these maturities, as of June 30, 2003, the Company’s investment portfolio did not include any short-term investments.

32

The Company’s borrowing consists solely of its advance from the Institute, which is subject to potential repayment in the event that Cortex enters an AMPAKINE compound into Phase III clinical testing as a potential treatment for Alzheimer’s disease. Potential repayment would include interest accruing at a discount to the prime lending rate. Changes in interest rates generally affect the fair value of such debt, but, based upon historical activity, such changes are not expected to have a material impact on earnings or cash flows. As of June 30, 2003, the principal and accrued interest of the advance amounted to $270,140.

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. (the “Company”) as of June 30, 2003 and 2002, and the related statements of operations, stockholders’ equity (deficit) and cash flows for the years ended June 30, 2003, 2002 and 2001. 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 auditing standards generally accepted in the United States. 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. at June 30, 2003 and 2002, and the results of its operations and its cash flows for the three years then ended, in conformity with accounting principles generally accepted in the United States.

As discussed in Note 1 to the financial statements, in 2001 the Company changed its revenue recognition policy.
