PART I

Overview / Corporate History

CytoDyn Inc. (the “Company”), is a Colorado corporation, with its principal business office at 110 Crenshaw Lake Road, Lutz, Florida 33548; telephone: (813) 527-6969, facsimile: (813) 527-6970, and website address: www.cytodyn.com. We are a development stage biotechnology company (concept company) focused on discovering and developing a class of therapeutic monoclonal antibodies to treat Human Immunodeficiency Virus (“HIV”) infection. In addition, we formed a wholly owned subsidiary, CytoDyn Veterinary Medicine LLC (“CVM”), which will explore the possible application of our existing proprietary monoclonal antibody technology to the treatment of Feline Immunodeficiency Virus, a retroviral infection in cats (“FIV”).

In October 2003, the Company (under its previous name RexRay Corporation) entered into an Acquisition Agreement with CytoDyn of New Mexico, Inc. Pursuant to the acquisition agreement, we acquired assets related to our leading drug candidate, Cytolin^®, including the assignment of the patent license agreement dated July 1, 1994 between CytoDyn of New Mexico, Inc. and Allen D. Allen covering three United States patents along with foreign counterpart patents which describe a method for treating HIV disease with the use of monoclonal antibodies. This includes issued U.S. Patent Nos. 5,424,066; 5,651,970 and 6,534,057, as well as European Patent Nos. 0690725 and 1438970. In addition, Hong Kong Patent No. 1067958,

We also acquired the federally registered trademarks, CYTODYN (U.S. Registration No. 2095498) and CYTOLIN (U.S. Registration No. 2095497), and a related design mark (U.S. Registration No. 2662777. The license acquired gives the Company the worldwide, exclusive right to develop, market and sell compounds disclosed by the patent claims, practice methods taught by the patent claims, and exploit specified technology related to the patents. The term of the license agreement is for the life of the patents of which the first will expire in 2013. The original expiration dates on the issued U.S. Patent Nos. 5,424,066; 5,651,970 and 6,534,057 are 2013, 2014 and 2013, respectively. The original expiration dates for the foreign patents listed above are in 2013 or 2014, if the required annuity fee payments are paid by September 21, 2012. The Company’s Cytolin-related patents referenced above are for a murine (mouse) version of the drug. The Company’s research on Cytolin^® to date has utilized the current murine version of the drug. However, on September 23, 2011, the Company filed a provisional patent application (Serial No. 61/534,942) in the United States for its humanized version of Cytolin^®, a monoclonal antibody for the treatment of HIV Infection.

The Company is also exploring other antibodies as potential therapeutics for FIV. On June 17, 2011, the Company filed a provisional patent application in the United States (Serial No. 61/498,029) for the use of these antibodies as well as selected small molecule antagonists and agonists for the treatment of FIV. On June 15, 2012, the Company filed an international patent application (Serial No. PCT/US2012/042693) claiming priority to this provisional patent application. On August 10, 2011, the Company filed an application for registration of the trademark CYTOFELINE, intended for use in conjunction with veterinary preparations for the treatment of FIV (U.S. App. Ser. No. 85393956). In February 2012, the Company filed foreign trademark applications claiming priority to the US application for CYTOFELINE, including Australian App. No. 1473043, Canadian App. No. 1563313, European CTM App. No. 010625192, Indian App. No. 2279431, Japan App. No. 2012-008009, Mexican App. No. 1247597, and a Chinese App. No. 10475960. Thus far, the Company has received a Certificate of Trademark Registration from Japan No. 5488875, with an effective registration date of April 20, 2012, and a Certificate of Trademark Registration from the European Union No. 010625192 with an effective registration date of June 11, 2012. Additionally, the Company’s Australian App. No. 1473043 was registered on May 31, 2012.

Research History of Cytolin Compound

Cytolin^® is part of a class of drugs called monoclonal antibodies. It targets a normal cell molecule called CD11a, part of the heterodimer that makes up the cell adhesion molecule lymphocyte function cell associated antigen (“LFA-1”). Published reports have suggested that blocking or engaging CD11a might somehow limit or prevent HIV infection of CD4 cells and monocytes. In 1993, six HIV-infected patients were treated with murine Cytolin^®. Blood and skin tests of these patients suggested that the antibody might be producing improvements in the

immune function of each patient. Based on the results of this pilot study, a compassionate use trial was initiated. In this study a relatively small number of physicians in the United States administered Cytolin^® to their HIV-infected patients over two years. As results from this initial use became available, other physicians obtained and administered Cytolin^® to their patients as well. Four of the doctors using Cytolin^® allowed the Company’s predecessor to send in an independent Institutional Review Board to inspect the medical records of approximately 200 patients treated with Cytolin^® once or twice a month over 18 months. Data were recorded and summarized and formed part of the material presented to the U.S. Food & Drug Administration (the “FDA”) as an early indication of the safety and potential efficacy of Cytolin^®.

In 1996, the FDA approved a drug master file, designated BB-DMF#6836, for the manufacture of murine Cytolin^® at Vista Biologicals Corporation. CytoDyn of New Mexico, Inc. (a predecessor to the Company) and Vista Biologicals Corporation worked cooperatively to develop the drug master file. In accordance with the practice of the FDA, the drug master file was issued to and became the property of the entity with the capacity to manufacture the drug, in this case Vista Biologicals Corporation. By contract with Vista Biologicals Corporation, CytoDyn of New Mexico, Inc. had the exclusive right to reference the drug master file, that is, to authorize Vista Biologicals Corporation to manufacture Cytolin^® in accordance with the terms of the drug master file.

In 1996, the FDA also designated our investigational new drug application for murine Cytolin^® as BB-IND #6845, and subsequently approved a clinical trial. In 2002, Symbion Research International, a contract research organization, completed a Phase I a/b clinical trial of Cytolin^® (a Phase I trial includes the initial introduction of an investigational new drug or biologic into humans). The trial was sponsored by Amerimmune, Inc., the previous licensee of CytoDyn of New Mexico, Inc. but Symbion was never paid for its work. As a result, its work product became Symbion’s. We entered into a buy-sell agreement with Symbion to purchase the Phase Ia study data in 2004. The Phase Ia study, conducted in 13 subjects suffering from HIV/Acquired Immune Deficiency Syndrome (“AIDS”), found Cytolin^® to be safe and well tolerated. The initial safety study supported the safety and tolerability of the drug in these dose groups. Some of the data was presented as an abstract and poster session, entitled “Phase I Study of Anti-LFA-1 Monoclonal Antibody (Cytolin^® in Adults with HIV Infection)” at the 9th Conference on Retroviruses and Opportunistic Infections held in Seattle, Washington on February 24-28 2002 as well as the 16th International AIDS Conference held August 2006 in Toronto, Canada. The Company then went through a period of years where legal issues delayed the progress of this treatment.

To date, only the murine version of Cytolin^® has been tested in clinical, research and development studies. The Company understands that registrational studies will require similar testing and confirmation of activity with its proprietary humanized version of Cytolin^®.

Cytolin - Current Research

Under a Clinical Trial Agreement dated September 28, 2009 and as amended to date (the “Clinical Trial Agreement”), in exchange for a research grant by the Company, Massachusetts General Hospital (“MGH”) in Boston, Massachusetts agreed to conduct an ex-vivo study of murine Cytolin^® in accordance with a study protocol entitled “An observational study to determine the in-vitro immunologic and virology activity of Cytolin” (the “Study”). In addition to providing financial support for the Study, the Company agreed to provide MGH with supplies of Cytolin^® needed for the Study. Under the Clinical Trial Agreement, Eric S. Rosenberg, M.D. is designated as the Principal Investigator for the Study.

Human subjects were recruited for the Study from Dr. Rosenberg’s clinic. The Study enrolled 10 adults with early HIV infection and 10 healthy adults as the control arm, all of whom were required to participate for six months. None of the patients enrolled in the study received injections of murine Cytolin^®; rather they donated blood to allow one to examine the effects of Cytolin^® when it was added in the test tube to their peripheral blood mononuclear cells. The Study design and objectives are available to view at the government’s website at www.clinicaltrials.gov, ID NCT01048372. The public has online access to this federal database, which describes elements of clinical trials and their status. To review public records for the Study on the government’s website, enter “Cytolin” as the search term (case sensitive).

The second amendment to the Clinical Trial Agreement provided that our research grant commitment for the Study would total $316,755. In March 2010, we agreed in a third amendment to the Clinical Trial Agreement to provide an additional $233,815 for the Study to enable the Principal Investigator to engage additional personnel. In December 2010, we further agreed in a fourth amendment to the Clinical Trial Agreement to provide an additional $25,000 for the Study. On May 20, 2011, we entered into a fifth amendment of the Clinical Trial Agreement with The General Hospital Corporation, d/b/a/ MGH to extend the Study enabling MGH Principal Investigator Eric Rosenberg, M.D., to further explore his initial findings regarding the potential mechanism of action of murine Cytolin^® to treat HIV-positive adults. Under the fifth amendment, we agreed to pay MGH the remaining unpaid balance of $291,590 of the total research grant of $865,375 over the six month period beginning on May 20, 2011 and ending on November 20, 2011. As of May 31, 2012, the final payment in the amount of approximately $72,898 due to MGH in connection with the Clinical Trial Agreement was past due. The Study was completed subsequent to May 31, 2012. The Company anticipates that if there is sufficient data to warrant publication Dr. Rosenberg will draft and submit a manuscript detailing his results. The release of this or any data from the Study is entirely dependent on Dr. Rosenberg.

The Study was a science-intensive research study and was not intended to function as a registrational study (see “Registrational Clinical Trials Process” below). The Company contemplates that the Study may be followed by a clinical trial that may or may not be conducted at MGH or with Dr. Rosenberg as the Principal Investigator. The Company will determine if clinical trials with the humanized version of Cytolin^® are warranted based on these and other results from studies with the murine molecule and subsequent confirmation of activity with the humanized version of Cytolin^®. There is no assurance that the results of the Study will warrant further clinical trials, or that a strategic alliance for humanized Cytolin^® will be available.

The Clinical Trial Agreement governs the parties’ rights in Study data and the results of the Study (“Study Data and Results”). MGH retains ownership of all Study Data and Results, and is obligated to provide the Company with a copy of such Study Data and Results. The Clinical Trial Agreement places limits on the Company’s ability to use Study Data and Results. Specifically, the Company is permitted to use Study Data and Results that disclose individually identifiable health information only for purposes of the Study or related studies that concern murine Cytolin^® or medical conditions / disease area that are the subject of the Study, however, the Company is permitted to use information that is not identifiable for any research and development purposes. These uses are further limited by the requirements that any such use comply with applicable law (including the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”)); and that the use is permitted by the informed consent form used with subjects in connection with the Study.

Why Cytolin May Be a Unique Treatment for Early HIV Infection

The particular epitope recognized by murine Cytolin^® is highly expressed on killer cells called cytotoxic T cells or CTLs. However, subsequent studies and analysis of the activity of Cytolin^® has shown that while Cytolin^® is highly expressed on CTLs, this antibody does not block CTLs. In addition to being expressed on CTLs, the CD11a protein has also been reported to be present on the surface of the HIV virion, presumably to assist in the infectious cycle of the virus. This opens the possibility that Cytolin^® may bind and neutralize HIV, providing a direct action against the virus in the bloodstream.

In addition to CTLs, murine Cytolin^® also recognizes and binds to dendritic cells (DCs). These two types of immune cells are critical to the control of viral burden in HIV infected individuals. By binding to these cells, it is also possible that Cytolin^® may induce an antiviral activity that may impede infection of new cells and presumably lead to a reduction in viral burden.

Acquisition of Advanced Genetic Technologies, Inc.

On January 30, 2007, we acquired, from Utek Corp., our subsidiary Advanced Genetic Technologies, Inc., which holds the exclusive right to develop alternative antibodies that bind to the same cellular target as murine Cytolin^®. These two monoclonal antibodies were invented at Harvard University Medical School’s CBR Institute for Biomedical Research. The Company has not used these two antibodies in our research and development efforts to date but we may use these in future research and development efforts.

Formation of CytoDyn Veterinary Medicine LLC and Current Research

On May 16, 2011, we formed a wholly owned subsidiary, CVM, which will explore the possible application of feline reactive monoclonal antibodies for the treatment of the feline immunodeficiency virus (“FIV”). We view the formation of CVM and the exploration of CD11a-specific monoclonal antibodies to treat FIV as an effort to strategically diversify the use of monoclonal antibody expertise.

On June 17, 2011, the Company filed a provisional patent application in the United States (Serial No. 61/498,029) for the use of certain antibodies as well as selected small molecule antagonists and agonists for the treatment of FIV. On June 15, 2012, the Company filed an international patent application (Serial No. PCT/US2012/042693) claiming priority to this provisional patent application. On August 10, 2011, the Company filed an application for registration of the trademark CYTOFELINE, intended for use in conjunction with veterinary preparations for the treatment of FIV (U.S. App. Ser. No. 85393956). In February 2012, the Company filed foreign trademark applications claiming priority to the US application for CYTOFELINE, including Australian App. No. 1473043, Canadian App. No. 1563313, European CTM App. No. 010625192, Indian App. No. 2279431, Japan App. No. 2012-008009, Mexican App. No. 1247597, and a Chinese App. No. 10475960. Thus far, the Company has received a

Certificate of Trademark Registration from Japan No. 5488875, with an effective registration date of April 20, 2012, and a Certificate of Trademark Registration from the European Union No. 010625192 with an effective registration date of June 11, 2012. Additionally, the Company’s Australian App. No. 1473043 was registered on May 31, 2012.

On November 16, 2011, the Company and The Scripps Research Institute, a nonprofit institution (“Scripps Research”) entered into a six-month Research Funding and Option Agreement (the “Scripps Agreement”) that enabled Dr. John H. Elder, Professor in the Department of Immunology and Microbial Science at Scripps Research, to explore the potential application of the Company’s recently provisionally patented technology as an effective therapy in the treatment of FIV. The Company has assigned the Scripps Agreement to CVM. This study has now been completed. Through the course of this work Dr. Elder was able to identify a panel of anti-human monoclonal antibodies to CD11a that cross react with feline CD11a. These antibodies limited FIV infection in cell culture. The Company anticipates that if the data warrants publication Dr. Elder will draft and submit a manuscript detailing his results. The release of this or any data from this study is entirely dependent on Dr. Elder. While the original six-month period contemplated under the Scripps Agreement has expired, the Company will continue to engage Dr. Elder and Thomas Fitting, Esq., Ph.D., Chief Patent Counsel at Scripps Research, as consultants on an as needed basis through July 12, 2013.

On February 15, 2012, the Company and Colorado State University (“CSU”) entered into a Research Funding and Option Agreement (the “CSU Agreement”) that will enable Dr. Susan VandeWoude Associate Dean for Research and Graduate Education, CVMBS; Professor, DMIP, to explore the potential application of the Company’s recently provisionally patented technology as an effective therapy in the treatment of FIV in infected cats. The Company has assigned the CSU Agreement to CVM. This study is designed to determine the effect of a single dose of murine CytoFeline^® on FIV RNA and DNA as well as a panel of other virologic and safety markers. The Company anticipates that if the data warrants publication Dr. VandeWoude will draft and submit a manuscript detailing her results. The release of this or any data from this study is entirely dependent on Dr. VandeWoude.

On June 19, 2012, Dr. VandeWoude and Dr. Richard Trauger, the Company’s Managing Director of Science, were awarded a grant of $27,000 by CSU to study the pharmacokinetics of a chimeric version of CytoFeline^® in uninfected cats. The Company expects to generate and provide the chimeric version of the antibody for Dr. VandeWoude in the next six months. The Company anticipates that if the data from the study warrants publication Dr. VandeWoude and Dr. Trauger will draft and submit a manuscript detailing these results.

Manufacturing and Source for Raw Materials

We negotiated with a contract manufacturer, Vista Biologicals Corporation (“Vista”), to manufacture murine Cytolin^® suitable for use in our current ex vivo clinical trial of Cytolin^® at a cost of $565,000, all of which was paid by September 2008. In February 2010, we entered into a statement of work for the development of a humanized form of Cytolin^® at a cost of $229,500. Vista entered into an assignment agreement with us to transfer all rights and title to certain inventions and applications to us in consideration for our forgiveness of certain disputed amounts under the contractual arrangements between the parties. There are ongoing negotiations related to the ultimate obligations of the Company and Vista under both the 2008 and 2010

contractual arrangements. Although a murine version of Cytolin^® was used for previous human experience that included approximately 200 patients treated for up to two years, as well as an encouraging uncontrolled Phase I(b)/II(a) study, and our current ex-vivo clinical trial, the Company understands that a fully-humanized version is necessary for the controlled clinical trials that are expected to follow the previous ones. On September 23, 2011, the Company filed a provisional patent application (Serial No. 61/534,942) in the United States for its humanized version of Cytolin^®, a monoclonal antibody for the treatment of HIV infection. The Company is currently in discussions with potential manufacturing sites to obtain clinical grade antibody for future clinical development of Cytolin^®.

The design, testing, manufacture, safety, effectiveness, labeling, storage, record keeping, approval, advertising and promotion of our products is regulated by numerous third parties, including the FDA, foreign governments, independent standards auditors and our customers.

In the United States, biological products have long been subject to regulation by various federal and state agencies, primarily as to product safety, efficacy, manufacturing, advertising, labeling, import, export and safety reporting. The exercise of broad regulatory powers by the FDA through its Center for Devices and Radiological Health and its Center for Biological Evaluation and Research continues to result in increases in the amounts of testing and documentation for FDA clearance of current and new biologic products. The FDA can ban certain biological products; detain or seize adulterated or misbranded biological products; order repair, replacement or refund of these products; and require notification of health professionals and others with regard to biological products that present unreasonable risks of substantial harm to the public health. The FDA may also enjoin and restrain certain violations of the Federal Food, Drug and Cosmetic Act, as amended, or the Public Health Service Act pertaining to certain biological products or initiate action for criminal prosecution of such violations.

The lengthy process of seeking drug approvals, and the subsequent compliance with applicable statutes and regulations, require the expenditure of substantial resources. Failure to comply with applicable regulations can result in refusal by the FDA to approve product license applications. The FDA also has the authority to revoke previously granted product approvals.

Regulation of Laboratory Operations

Clinical laboratories that perform laboratory testing (except for research purposes only) on human subjects are subject to regulation under Clinical Laboratory Improvement Amendments (“CLIA”). CLIA regulates clinical laboratories by requiring that the laboratory be certified by the federal government, licensed by the state and comply with various operational, personnel and quality requirements intended to ensure that clinical laboratory test results are accurate, reliable and timely. State law and regulations also apply to the operation of clinical laboratories.

State Governments

Most states in which we operate have regulations that parallel federal regulations. Most states conduct periodic unannounced inspections and require licensing under such state’s procedures. Our research and development activities and the manufacture and marketing of our products are and will be subject to rigorous regulations relating to product safety and efficacy by numerous governmental authorities in the United States and other countries.

Other Laws and Regulations

We are subject to various laws and regulations relating to safe working conditions, clinical, laboratory and manufacturing practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous substances, including radioactive compounds and infectious disease agents, used in connection with our research. The extent of government regulation applying to our business that might result from any legislative or administrative action cannot be accurately predicted.

Environmental

We are subject to a variety of federal, state and local environmental protection measures. We believe that our operations comply in all material respects with applicable environmental laws and regulations. Our compliance with these regulations did not have during the past year and is not expected to have a material effect upon our capital expenditures, cash flows, earnings or competitive position.

Registrational Clinical Trials Process

Described below is the traditional registrational drug development track. Under the Company’s current business plan, much of this initial work may be sponsored and conducted by MGH, or a different clinical trial research facility, as determined by us at some point in the future and different studies may also be explored. After these trials have been initiated, the Company could enter into a strategic alliance with a larger pharmaceutical company after development has progressed to a certain point. The Company is exploring all options available to determine the most cost effective implementation of the clinical trial process.

Phase I

Phase I includes the initial introduction of an investigational new drug or biologic into humans. These studies are closely monitored and may be conducted in patients, but are usually conducted in a small number of healthy volunteer subjects. These studies are designed to determine the metabolic and pharmacologic actions of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness. During Phase I, sufficient information about the investigational product’s pharmacokinetics and pharmacological effects are obtained to permit the design of well-controlled, scientifically valid, Phase II studies.

Table of Contents

Phase II

Phase II includes the early controlled clinical studies conducted to obtain some preliminary data on the effectiveness of the drug for a particular indication or indications in patients with the disease or condition. This phase of testing also helps determine the common short-term side effects and risks associated with the drug. Phase II studies are typically well-controlled, closely monitored, and conducted in a relatively small number of patients, usually involving several hundred people. In some cases, depending upon the need for a new drug, it may be licensed for sale in interstate commerce after a “pivotal” Phase II trial.

Phase III

Phase III studies are expanded controlled clinical studies. They are performed after preliminary evidence suggesting effectiveness of the drug has been obtained in Phase II, and are intended to gather the additional information about effectiveness and safety that is needed to evaluate the overall benefit/risk relationship of the drug. Phase III studies also provide an adequate basis for extrapolating the results to the general population and transmitting that information in the physician labeling. Phase III studies usually include several hundred to several thousand people.

The Company may fund clinical trials using venture capital or through the sale of our common stock or other equity securities, or, at that time, may enter into a strategic alliance for completion of research and the subsequent marketing of humanized Cytolin^® if approved. In the former case, and while the cost will be to some extent determined by the trial size, we currently estimate that we will need to provide additional humanized product, which we estimate will cost approximately $500,000. The Company intends to conduct one or more private placement offerings of common shares to secure the needed capital. We cannot estimate the cost of any potential follow up study or whether any of the planned private placement offerings will be successful.

Competition

The pharmaceutical and biotechnology industries are characterized by rapidly evolving technology and intense competition. We will compete with other more established biotechnology companies which have greater financial resources than we have.

Our potential competitors include entities that develop and produce therapeutic agents for treatment of human and animal disease. These include numerous public and private academic and research organizations and pharmaceutical and biotechnology companies pursuing production of, among other things, biologics from cell cultures, genetically engineered drugs and natural and chemically synthesized drugs. Almost all of these potential competitors have substantially greater capital resources, research and development capabilities, manufacturing and marketing resources and experience than we have. Our competitors may succeed in developing potential drugs or processes that are more effective or less costly than any that may be developed by us, or that gain regulatory approval prior to our potential drugs. Worldwide, there are many antiviral drugs for treating HIV and AIDS. In seeking to manufacture, distribute and market the various potential drugs we intend to develop, we face competition from established pharmaceutical companies. All of our potential competitors in this field have considerably greater financial and personnel resources than we possess. We also expect that the number of our competitors and potential competitors will increase as more potential drugs receive commercial marketing approvals from the FDA or analogous foreign regulatory agencies. Any of these competitors may be more successful than us in manufacturing, marketing and distributing our potential drugs.

Research and Development Costs

Our sponsored research and development expenses were $530,027, $480,765 and $2,759,495 in fiscal 2012, 2011 and for the period October 28, 2003 through May 31, 2012, respectively. We expect that research and development expenses will increase as we seek to expand development of our current and future product pipeline.

Employees

We have four full time employees, one part time employee, and a varying number of consultants engaged in management and product development. We are severely understaffed and will expand our employee force if we complete further financings. There can be no assurance we will be able to locate or secure suitable employees upon acceptable terms in the future.

Our principal offices were located at 1511 Third Street, Santa Fe, New Mexico 87505 for a portion of fiscal year 2011. We leased approximately 1,200 square feet under a lease from September 1, 2010 until August 31, 2011 at $1,650 per month.

On June 7, 2011, the Board approved the relocation of the Company’s principal office to Lutz, Florida. Effective as of June 15, 2011, the principal office of the Company is now located at 110 Crenshaw Lake Road, Lutz, Florida 33548. We use approximately 1,600 square feet on an at-will tenancy basis at a cost of $1,650 per month in rent plus sales tax and reimbursement for utilities. The building related to this lease is owned by an affiliate of Kenneth Van Ness, our President and Chief Executive Officer (“CEO”).

On or about December 22, 2011, William Carmichael and Mojdeh Javadi (the “Plaintiffs”) filed a complaint against the Company in the Circuit Court of the State of Oregon for the County of Clackamas, alleging breach of contract. The Plaintiffs alleged that the Company entered into a contract with the Plaintiffs in November 2007, then breached the terms of the contract by failing to issue warrants to the Plaintiffs entitling them to purchase shares of the Company’s stock (the “Breach of Contract” claims). The Plaintiffs filed an Amended Complaint against the Company on May 11, 2012 in which they asserted three additional claims each and amended the relief requested. In addition to the Breach of Contract claims, the Plaintiffs alleged in their Amended Complaint that: (i) they were third-party beneficiaries of a promise made by the Company to Nader Pourhassan in a Personal Services Agreement (the “Personal Services Agreement”), dated August 4, 2008 (the “Third Party Beneficiary” claims), (ii) they provided services to the Company and were entitled to the reasonable value for such services (the “Quantum Meruit” claims), and (iii) in reliance on the promises made in the Personal Services Agreement, the Company induced them to provide services to the Company and they were entitled to compensation for damages resulting from their reliance on those promises (the “Promissory Estoppel” claims). The Quantum Meruit and Promissory Estoppel claims were alternative claims to their Third Party Beneficiary claims. On the Breach of Contract claims, the Plaintiffs sought either compensatory damages in an amount not less than $750,000 each or the delivery of warrants to each Plaintiff to purchase 375,000 shares of the Company’s common stock for $0.25 per share. With respect to the Third Party Beneficiary claims, the Plaintiffs sought a judgment requiring the Company to deliver 650,000 shares of its common stock to each Plaintiff. With respect to the Quantum Meruit claims, Plaintiffs sought compensatory damages in an amount equal to the reasonable value of their services to the Company. With respect to the Promissory Estoppel claims, the Plaintiffs sought compensation for damages resulting from their reliance on the Company’s promises. The Plaintiffs also sought prejudgment interest, plus costs and disbursements incurred in the litigation. The Company filed an answer to the complaint on February 15, 2012. An answer to the Amended Complaint was filed on May 21, 2012.

On July 27, 2012, the Company entered into a Settlement Agreement and Mutual Release (the “Settlement Agreement”) with the above Plaintiffs. Pursuant to the Settlement Agreement, the Company issued 200,000 shares of the Company’s common stock (“Shares”) to each of the Plaintiffs, for an aggregate total of 400,000 Shares. In addition, the Company issued warrants (“Warrants”) to purchase up to 375,000 Shares to each of the Plaintiffs, for an aggregate total of 750,000 Warrants. The Warrants are immediately exercisable at $0.25 per Share and shall expire on August 15, 2012. The Company issued the Shares and the Warrants to the Plaintiffs in exchange for their full and complete release of any and all claims against the Company as of July 27, 2012. Pursuant to and in accordance with the Settlement Agreement, on July 30, 2012, the Plaintiffs also dismissed with prejudice and without any award of costs, disbursements or attorney’s fees, their Amended Complaint against the Company filed in the Circuit Court of the State of Oregon for the County of Clackamas. As of May 31, 2012, the Company recognized approximately $540,000 and $388,000 of compensation expense related to the Warrant grant, and the issuance of the Shares, respectively.

In addition, from time to time, we are involved in claims and suits that arise in the ordinary course of our business. Management currently believes that resolving any such claims against us will not have a material adverse impact on our business, financial position or results of operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the other sections of this Annual Report, including our consolidated financial statements and related notes appearing elsewhere herein. This discussion and analysis contains forward-looking statements including information about possible or assumed results of our financial conditions, operations, plans, objectives and performance that involve risk, uncertainties and assumptions. The actual results may differ materially from those anticipated and set forth in such forward-looking statements.

Results of Operations

Results of operations for the year ended May 31, 2012 compared to May 31, 2011 are as follows:

For the years ended May 31, 2012 and 2011, we had no activities that produced revenues from operations.

For the year ended May 31, 2012, we had a net loss of approximately $7,474,000 compared to a net loss of approximately $3,720,000 for the corresponding period in 2011. For the year ended May 31, 2012 and 2011, we incurred operating expenses consisting primarily of stock-based compensation, accounting and consulting, research and development, salary, legal expenses, and various other selling and administrative expenses.

The operating expenses for the years ended May 31, 2012 and 2011 are as follows:

Accounting and consulting expenses increased approximately $250,000 from $274,000 in fiscal year 2011 to approximately $524,000 at May 31, 2012. Accounting expenses increased as the Company utilized more temporary accounting staff, as well as increased edgarization costs related to the Company’s increased filings with the Securities and Exchange Commission (“SEC”). The increase in consulting expenses relates primarily to the issuance of common stock to consultants for services, as well as the Company entering into a consulting agreement with the Company’s former CEO in the first quarter of fiscal year 2012.

Stock-based compensation increased approximately $1,672,000 from approximately $1,186,000 at May 31, 2011 to $2,858,000 at May 31, 2012. The increase relates to options grants made to certain executives of the Company pursuant to employment agreements, as well

17

Table of Contents

as warrants granted to certain consultants with immediate vesting rights. Additionally, as disclosed in “Item 3. Legal Proceedings” and footnotes 9 and 11 to the consolidated financial statements, the Company granted warrants and common stock pursuant to the Settlement Agreement. During fiscal year 2011, there were less option grants, and no grants with immediate vesting rights. The Company expects to continue to grant stock options in the future, and accordingly, stock-based compensation should continue to be a significant expense in the future.

Legal expenses increased approximately $780,000 from approximately $689,000 at May 31, 2011 to $1,469,000 at May 31, 2012 due to a variety of matters, including assistance with: (i) litigation as discussed at footnote 9 of the consolidated financial statements; (ii) preparation or review and negotiation of contracts such as with third-party providers and employment agreements; (iii) responding to an investigation by the SEC; (iv) the Company’s SEC filings and corporate compliance; (v) ongoing claims and litigation and other disputes and the negotiation of associated proposed and/or final settlements with certain third parties; (vi) the Company’s ongoing fundraising efforts and related securities law research with respect to the Company’s past and current fundraising efforts; (vii) extensive negotiation and drafting of the Asset Purchase Agreement and related documentation relating to the Company’s proposed acquisition of PRO 140 from Progenics Pharmaceuticals, Inc., as discussed in footnote 11 to the consolidated financial statements; and (viii) extensive research and review of Company records in order to facilitate bringing the Company’s SEC filings into compliance. The trend in the Company’s legal expenses will depend on the Company’s ability to raise proceeds and to hire additional staff who can perform certain functions that can help defray legal expenses.

Salaries increased approximately $923,000 from approximately $700,000 in fiscal year 2011 to $1,623,000 in fiscal year 2012. The significant increase relates to the execution of executive employment contracts during fiscal year 2012, as well as the payment of certain discretionary bonuses to executives. The executive salaries in fiscal 2012 were significantly higher for certain executives relative to fiscal year 2011. Bonuses to executives are either based on achievement of targeted annual performance goals recommended by the compensation committee and approved by the Board, or are discretionary in nature based on Board approval. During fiscal year 2012, the Company granted discretionary bonuses of approximately $335,000. There were no bonuses granted during fiscal year 2011.

Research and development expenses increased approximately $49,000 from approximately $481,000 in fiscal year 2011 to $530,000 in fiscal year 2012. The increase relates primarily to the Company entering into a consulting agreement for research related to the development of FIV therapeutics.

Other expenses are comprised of various selling and administrative expenses which increased approximately $85,000 from approximately $365,000 in fiscal year 2011 to $450,000 in fiscal year 2012. The increase relates primarily to increases in investor relation costs, healthcare costs pursuant to employment agreements, and numerous other smaller increases.

The increase or decrease in the above expenses will depend on the Company’s ability to raise additional capital and ultimately fund the Company’s clinical trials, and fund other operating costs as deemed necessary.

Rescission Liability

The Company estimates an amount that is a probable indicator of the rescission liability and has recorded rescission liabilities for May 31, 2012 and May 31, 2011 of approximately $3,749,000 and $4,851,000, respectively. These amounts represent the believed potential rescission liability as of the dates presented, including any contingent interest payable to investors who accept the rescission right, and forfeit their shares. For the purpose of calculating and disclosing rescission liability, the Company has assumed that portions of the state claims are barred by the statutes of limitations of certain states based upon a literal interpretation of the applicable statute. Although the Company has assumed that affirmative defenses based upon the expiration of the statutes of limitations in these states may be generally available to bar these state claims, it has not had legal counsel undertake a detailed analysis of case law that might apply to defer or avoid application of a bar to such claims; thus, if rescission claims are made for those assumed to be barred by a statute of limitations and such claims are contested by the Company, until such affirmative defenses are ruled upon by judge in a proceeding adjudicating the rights at issue, no assurances can be made that, if asserted, such defenses would actually bar the rescission claims in these states. See Footnote 3 of our Consolidated Financial Statements on page 51 for further information regarding these rescission liabilities.

Accrued Incentive Stock Compensation

On August 4, 2008, the Company entered into the Personal Services Agreement with Nader Pourhassan. The Personal Services Agreement provided for compensation to Dr. Pourhassan at an annual salary of $200,000. Additionally, as incentive compensation, Dr. Pourhassan’s personal assistant and one additional person were to receive 50,000 common shares each of Company stock for every $500,000 in capital received by the Company through Dr. Pourhassan’s efforts. As of May 31, 2010, the Company accrued $1,180,000 related to the Personal Services Agreement. Subsequent to the fiscal year ended May 31, 2011, Dr. Pourhassan and the Company entered into a Mutual Release and Personal Services Termination Agreement (the “MRPSTA”) which relieves the Company of liability for any claims of compensation under the Personal Services Agreement. Simultaneously, with the signing of the MRPSTA, Dr. Pourhassan and the Company entered into a new Employment and Non-Compete Agreement whereby Dr. Pourhassan will serve as Managing Director of Business Development at an annual salary of $200,000. See Footnote 3 of our Consolidated Financial Statements on page 51 for further information.

The Company had been accruing stock compensation and deferred offering costs related to the Personal Services Agreement as described at Note 3. Upon the signing of the MRPSTA, the Company at May 31, 2011 reversed all accrued stock compensation and deferring offering costs, as the Company currently has no further obligations under the Personal Services Agreement.

Liquidity and Capital Resources.

On May 31, 2012, we had negative working capital of approximately $4,007,000 as compared to a negative working capital of approximately $5,022,000 on May 31, 2011.

Cash Flows

Net cash used in operating activities was approximately $4,391,000 during fiscal year 2012, which reflects an increase of approximately $2,570,000 from net cash used in operating activities of approximately $1,821,000 in 2011. The increase in the net cash used in operating activities for the above periods was primarily attributable to the following:

The above increases were partially offset by stock-based compensation increasing approximately $1,672,000 from 2011 to 2012.

There were no other significant changes in cash used in operating activities from 2011 to 2012.

There were no material changes in cash flows from investing activities from 2011 to 2012.

Cash flows provided by financing activities of approximately $3,638,000 during fiscal year 2012 increased approximately $2,510,000 from approximately $1,128,000 during 2011. The increase in cash provided by financing activities for the above periods was attributable primarily to the increase in proceeds from the sale of common stock and the exercise of common stock options and warrants.

There were no other significant changes in cash provided by financing activities from 2011 to 2012.

As shown in the accompanying consolidated financial statements, for the year ended May 31, 2012 and 2011, and since October 28, 2003 through May 31, 2012 we incurred net losses of approximately $7,474,000 and $3,720,000 and $22,833,000, respectively. As of May 31, 2012, we have not emerged from the development stage. In view of these matters, our ability to continue as a going concern is dependent upon our ability to begin operations and to achieve a level of profitability. Since inception, we have financed our activities principally from the sale of public and private equity securities and proceeds from notes payable. We intend to finance our future development activities and our working capital needs largely from the sale of equity securities with some additional funding from other traditional financing sources.

As previously mentioned, since October 28, 2003, we have financed our operations largely from the sale of common stock and preferred stock and proceeds from notes payable. From October 28, 2003 through May 31, 2012 we raised cash of approximately $10,504,000 (net of offering costs) through private placements of common stock, treasury stock and preferred stock financings and $1,537,000 through the issuance related party notes payable and convertible notes. The Company has raised approximately $612,000 from the issuance of common stock and preferred stock in conjunction with certain acquisitions in prior years. Additionally, the Company raised approximately $355,000 from the exercise of common stock options and warrants. In April 2010, our shareholders voted to amend our Articles of Incorporation to increase the number of authorized shares of common stock to 100,000,000 shares; accordingly, we intend to continue to finance our operations through the sale of our shares.

20

Table of Contents

Since October 28, 2003 through May 31, 2012, we have incurred approximately $2,759,000 of research and development costs and approximately $22,295,000 in operating expenses. We have incurred significant net losses and negative cash flows from operations since our inception. As of May 31, 2012, we had an accumulated deficit of approximately $24,435,000 and negative working capital of approximately $4,007,000.

We anticipate that cash used in product development and operations, especially in the marketing, production and sale of our products will increase significantly in the future. We currently do not have any significant material commitments related to capital expenditures. As described above, we do have material commitments related to our current Study (as defined above) of our product with MGH, and have potential obligations under our contracts with Vista.

Going Concern

We will require additional funding in order to continue with research and development efforts.

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the accompanying consolidated financial statements, the Company is currently in the development stage with losses for all periods presented. As of May 31, 2012 these factors, among others, raise substantial doubt about the Company’s ability to continue as a going concern.

The consolidated financial statements do not include any adjustments relating to the recoverability and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company’s continuation as a going concern is dependent upon its ability to obtain additional operating capital, complete development of its medical treatments, obtain FDA approval, outsource manufacturing of the treatments, and ultimately to attain profitability. The Company intends to seek additional funding through equity offerings or licensing agreements to fund its business plan. There is no assurance that the Company will be successful in these endeavors.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

21

Table of Contents

We believe that the following critical policies affect our more significant judgments and estimates used in preparation of our consolidated financial statements.

We use the Black-Scholes option pricing model to estimate the fair value of stock-based awards on the date of grant utilizing certain assumptions that require judgments and estimates. These assumptions include estimates for volatility, expected term, and risk-free interest rates in determining the fair value of the stock-based awards.

We issue common stock to consultants for various services. Costs for these transactions are measured at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more readily measurable. This determination requires judgment in terms of the consideration being measured.

We estimated an amount that is a probable indicator of our rescission liability and will record rescission liabilities for May 31, 2012 and May 31, 2011 of $3,749,000 and $4,851,000, respectively. These amounts represent the believed potential rescission liability as of the dates presented, including any contingent interest payable to investors who accept the rescission right, and forfeit their shares. For the purpose of calculating and disclosing rescission liability, the Company has assumed that portions of the state claims are barred by the statutes of limitations of certain states based upon a literal interpretation of the applicable statute. Although the Company has assumed that affirmative defenses based upon the expiration of the statutes of limitations in these states may be generally available to bar these state claims, it has not had legal counsel undertake a detailed analysis of case law that might apply to defer or avoid application of a bar to such claims; thus, if rescission claims are made for those assumed to be barred by a statute of limitations and such claims are contested by the Company, until such affirmative defenses are ruled upon by judge in a proceeding adjudicating the rights at issue, no assurances can be made that, if asserted, such defenses would actually bar the rescission claims in these states. See Footnote 3 of our Consolidated Financial Statements on page 51 for further information.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

CytoDyn Inc. (A Development Stage Company)

Lutz, Florida

We have audited the accompanying consolidated balance sheets of CytoDyn Inc. (a development stage company) as of May 31, 2012 and 2011 and the related consolidated statements of operations, changes in stockholders’ equity (deficit), and cash flows for the years then ended and the period from October 28, 2003 through May 31, 2012. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. The Company is not required at this time, to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of CytoDyn Inc. as of May 31, 2012 and 2011 and the results of its operations and its cash flows for the years then ended and the period from October 28, 2003 through May 31, 2012 in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company incurred a net loss of $7,474,224 for the year ended May 31, 2012, has a working capital deficit of $4,006,969, and has an accumulated deficit of $24,434,518 from the date of inception through May 31, 2012, which raises a substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
