You should read this summary together with the entire prospectus, including our financial statements, the notes to those financial statements, and the other documents identified under the headings “Where You Can Find More Information” and “Documents Incorporated by Reference” in this prospectus before making an investment decision.

for a discussion of the risks involved in investing in our securities.

Oxygen Biotherapeutics, Inc. is
Company Overview
We are engaged in the business of developing biotechnology products with a focus on oxygen delivery to tissue.specific target tissues. We are currently developing Oxycyte™Oxycyte®, a systemic perfluorocarbon, or PFC, product we believe is a safe and effective alternative to transfused bloodoxygen carrier for use in surgical and similar medical situations. We are pursuing applicationsituations of the same perfluorocarbon oxygen carrier technology to development of topical wound healing therapies.acute ischemia. In addition, we have developed a family of perfluorocarbon-based oxygen carriers for future development Fluorovent™, an oxygen exchange fluiduse in personal care, topical wound healing, and other topical indications. While Oxycyte has been successful in two clinical trials and is currently being evaluated in a Phase II-b clinical trial for facilitating the treatment of lung conditions. traumatic brain injury, or TBI, we also plan to focus on developing our most advanced topical products: Dermacyte® and Wundecyte™, as we believe these products have a significant opportunity for near-term commercialization.
Oxycyte
Our Oxycyte oxygen carrier product is a PFC-based oil in water emulsion, which is provided to the patient intravenously. The physical-chemical properties of PFCs enable our product to concentrate oxygen from the lungs and transport it through the body releasing it along the way. Over a period of days Oxycyte is gradually exhaled through the lungs during the normal process of respiration. Oxycyte requires no cross matching, so it is immediately available and compatible with all patients’ blood types. Oxycyte has an extended shelf life compared to blood and is provided as a sterile emulsion ready for intravenous administration. Because it contains no biological components, there is reduced risk of transmission of blood-borne viruses from human blood products. Further, since Oxycyte is based on readily available inert compounds, we believe it can be manufactured on a cost-effective basis in amounts sufficient to meet demand.
We recently licensedreceived approval of our Investigational New Drug application, or IND, for severe TBI filed with the U.S. Food and Drug Administration, or FDA, and began Phase I clinical studies in October 2003, which were completed in December 2003. We submitted a report on the results to the FDA along with a Phase II protocol in 2004. Phase II-A clinical studies began in the fourth quarter 2004, and were completed in 2006. A further Phase II study protocol was filed with the FDA in the spring of 2008, but remained on clinical hold by the FDA due to safety concerns raised by the regulatory agency. . In March 2011, we received confirmation of a $2.07 million, two-year cost reimbursement award from the U.S. Army to conduct safety related studies for Oxycyte. PFC emulsions, as a therapeutic class, are known to interact with the reticuloendothelial system as part of the clearance mechanism, as well as affect the number of circulating platelets. The studies supported by this grant will examine the effects of Oxycyte on the immune system, platelet function and distribution, as well as the safety and efficacy of platelet transfusion, which can be necessary for patients with TBI and related polytrauma. Additional studies under this grant will be conducted to evaluate the pharmacokinetics of PFCs in relevant species. We believe the results of these studies will support the safety profile of Oxycyte PFC emulsion and adequately address the FDA’s safety concerns. The aforementioned comprehensive preclinical program is under way, and we have sought FDA input and guidance with the aim of ensuring that the data collected will answer the questions regulators raise. We expect to commit a substantial portion of our financial and business resources over the next three years to testing Oxycyte and advancing this product to regulatory approval for use in one or more medical applications.
Despite the FDA’s postponement of Oxycyte trials in the United States, we are authorized to continue our TBI clinical studies abroad. After receiving the FDA clinical hold, we filed a revised protocol as a dose-escalation study with the regulatory authorities in Switzerland and Israel. The relevant Swiss regulatory body approved the protocol in August 2009, and the Israel Ministry of Health approved the protocol in September 2009. The new study began in October 2009. In March 2010, we determined that it is feasible to simplify the trial design and also reduce the number of patients to be enrolled. In May 2010, we entered into a relationship with a contract research organization, or CRO, to assist us with plans to expand our study, possibly into India, and to initiate five to 10 new sites for our Phase IIb clinical trial. At that time, we believed study objectives as well as safety and efficacy endpoints would remain unchanged, and we believed the study could be concluded faster and more economically with these optimizations. The first of three cohorts has been completed and we were authorized by the Swiss and Israeli regulatory authorities to initiate the second cohort. Despite their authorization, we stopped enrollment in order to reevaluate the protocol’s patient enrollment parameters, secure our cGMP supply of Oxycyte, review our contractor and clinical sites, and examine the possibility of opening clinical sites in other countries. At this time, we have secured our cGMP supply of Oxycyte. We are in the process of reviewing our CRO agreement and existing clinical sites. Our objective is to resume enrollment in the second cohort during the third quarter of fiscal year 2013. Upon completion of the Phase II trials, a Phase III trial will need to be implemented. In that instance, we would seek a partner to either conduct the Phase III trials, or collaborate with us to conduct the trials.
2

Should Oxycyte successfully progress in clinical testing and if it appears regulatory approval for one or more medical uses is likely, either in the United States or in another country, we intend to evaluate our options for commercializing the product. These options include licensing Oxycyte to a third party for manufacture and distribution, manufacturing Oxycyte ourselves for distribution through third party distributors, manufacturing and selling the product ourselves, or establishing some other form of strategic relationship for making and distributing Oxycyte with a participant in the pharmaceutical industry. We are currently investigating and evaluating all options.
Dermacyte
The Dermacyte line of topical cosmetic products contains our patented PFC technology and other known cosmetic ingredients to promote the appearance of skin health and other desirable cosmetic benefits. Dermacyte is designed to provide a moist and oxygen-rich environment for the skin when it is applied topically, even in small amounts. Dermacyte Concentrate has been formulated as a cosmetic in our lab and Dermacyte Eye Complex was created by a contract formulator, with the patent held by Oxygen Biotherapeutics. Both formulas have passed required safety and toxicity tests in the United States, and we have filed a Cosmetic Product Ingredient Statement, or CPIS with the FDA. The market for oxygen-carrying cosmetics includes anti-aging, anti-wrinkle, skin abrasions and minor skin defects.
In September 2009, we started production of our first commercial product under our topical cosmetic line, Dermacyte Concentrate. We produced and sold a limited pre-production batch in November 2009 as a market acceptance test. The product was sold in packs of 8 doses of 0.4ml. Based on the test market results we identified specific market opportunities for this product and reformulated Dermacyte Concentrate for better product stability. Marketing and shipments of the new Dermacyte Concentrate formulation began in April 2010. We worked with a contract formulator in California to develop the Dermacyte Eye Complex which contains PFC technology as well as other ingredients beneficial to the healthy appearance of the skin around the eyes.
Since June 2010 we have marketed and sold these products through www.DermacyteUS.com (previously www.buydermacyte.com) and to dermatologists, plastic surgeons and medical spas with a combination of in-house sales, independent sales agents and exclusive distributors. We had hired a sales director based in North Carolina, and had added sales people in South Florida and California. From October 2011 through February 2012, we evaluated that sales strategy. The outcome was that we adjusted our growth strategy to focus exclusively on the North Carolina and South Florida markets while we focused on developing new, improved packaging for the existing commercial products, as well as reformulating the products, and expanding the line to include more skin care products.
On February 5, 2013, we entered into a License and Supply Agreement (the “Dermacyte Agreement”) with the Cosmetics Division of Valor SA, or Valor, with respect to Dermacyte. The Dermacyte Agreement grants Valor the exclusive right to sell, import, export, distribute, package, label and otherwise commercialize Dermacyte worldwide for a five year term. Valor is also authorized to sublicense the license granted under the Dermacyte Agreement provided that such sublicenses are consistent with the terms of the Dermacyte Agreement. The Dermacyte Agreement will become effective upon our receipt from Valor of 75% of the estimated costs to complete certain product formulation and safety studies requested by Valor.
Under the Dermacyte Agreement, Valor will purchase bulk Dermacyte from us for 125% of our actual manufacturing cost, and must pay us an annual, non-refundable license fee of $140,000, payable on a quarterly basis, with the first year’s payment creditable against Dermacyte purchased by Valor in the first 12 months following the effective date of the Dermacyte Agreement. Valor must also pay us royalties of 5% of net sales of Dermacyte once Valor’s aggregate net sales of Dermacyte equals or exceeds $10,000,000.
Dermatology
We intend to develop additional clinical research protocols and conduct proof-of-concept studies for topical indications, such as the treatment of acne, rosacea, pruritis, psoriasis, and dermatitis. In January 2012 we initiated our first proof-of-concept study in India to assess the potential of our topical gel to reduce the itch (pruritis) associated with histamine-mediated allergic skin reactions. In May 2012, we revealed results of this study which showed that our topical gel elicited a larger reduction in Visual Analogue Scale scores following a standard histamine skin prick compared to placebo. The sample size of this study prevented a demonstration of statistical significance so further research is necessary to evaluate its effectiveness. We believe that we will need the support of partners in this sector to commercialize these dermatologic product candidates. We can provide no assurance that the topical indications we have under development will prove their claims and be successful commercial products.

Wundecyte
Wundecyte is a novel gel developed under a contract agreement with a lab in Virginia that is designed to be used as a wound-healing gel. In July 2009, we filed a 510K medical device application for Wundecyte with the FDA. Several oxygen-producing and oxygen-carrying devices were cited as predicate devices. The FDA response was that the application likely would be classified as a combination device. The drug component of the combination device will require extensive preclinical and clinical studies to be conducted prior to potential commercialization of the product.
We have also developed a prototype for an oxygen-generating bandage that can be combined with Wundecyte gel. Wundecyte gel and the oxygen-generating bandage both entered preclinical testing in our biosensor implantfirst quarter of fiscal 2011. The studies were designed to measure factors such as time to wound closure and reduction in scar tissue formation as compared to a control group. Results showed an apparent increase in epithelial thickness versus the control. The treatment did not cause adverse effects and the models tolerated the treatment well. Our current product development plan is for Wundecyte to emerge into more complex wound-healing indications, also in combination with oxygen-producing technologies based on hydrogen peroxide. In December 2010 we signed a binding letter of intent with Sarasota Medical Products, Inc., or SMP, of Sarasota, Florida to determine the feasibility of pursuing a joint research and development venture for treating chronic ischemic wounds. The venture was to be based on combining Wundecyte with SMP’s topical medical devices. No significant development activities have resulted from this agreement as of January 31, 2013.
Recent Developments
As of March 13, 2013, we have cash and cash equivalents of $1.7 million. We believe that usesour existing cash and cash equivalents will be sufficient to fund our projected operating requirements through July 31, 2013. We will need substantial additional capital in the future in order to complete the development and commercialization of Oxycyte and to fund the development and commercialization of our future product candidates. Until we can generate a sufficient amount of product revenue, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. Such funding, if needed, may not be available on favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses.
While our common stock is currently listed on the NASDAQ Capital Market, or NASDAQ, we are not currently in compliance with NASDAQ’s continued listing standards, and NASDAQ notified us by letter dated March 20, 2013 of the Staff’s decision to delist our securities from NASDAQ. The letter provides that, unless we request an enzyme processappeal of this determination, trading of our common stock will be suspended at the opening of business on April 1, 2013, and a Form 25-NSE will be filed with the Securities and Exchange Commission to remove our securities from listing and registration on NASDAQ. We intend to appeal NASDAQ’s determination by requesting a hearing before a NASDAQ Listing Qualifications Panel (the “Panel”) to seek continued listing pending our return to compliance. While the appeal is pending, our securities will not be delisted and the Form 25-NSE will not be filed. However, there can be no assurance that the Panel will grant the Company’s request for measuringcontinued listing or that we will be able to regain compliance with NASDAQ listing standards within the glucose level in subcutaneous fluid.

Risk Factors
An investment in our securities is speculative and involves a high degree of risk. You should carefully consider the risks under the heading “Risk Factors” beginning on page 8 of our Annual Report on Form 10-K for the fiscal year ended April 30, 2012, filed with the SEC on July 25, 2012, and our Quarterly Report on Form 10-Q for the fiscal quarter ended January 31, 2013, filed with the SEC on March 18, 2013, which information is incorporated by reference in this prospectus, may contain certain “forward-looking” statements withinand the meaning of certain securities laws, includingadditional risks described below and other information in this prospectus and the “safe harbour” provisionsdocuments incorporated by reference before deciding to invest in our securities. If any of the United States Private Securities Litigation Reform Actfollowing risks actually occur, our business, results of 1995operations, financial condition and cash flows could be materially adversely affected, the trading price of our common stock could decline significantly, and you might lose all or part of your investment. Additional risks and uncertainties that we are unaware of or that we believe are not material at this time could also materially adversely affect our business, financial condition or results of operations. In any case, the value of our securities could decline, and you could lose all or part of your investment, or our use of the offering proceeds may not yield a favorable return on your investment. You should also refer to our financial statements and the notes to those statements, which are incorporated by reference in this prospectus.
Risks Relating to the Offering
Our use of the offering proceeds may not yield a favorable return on your investment.
We currently intend to use the net proceeds received from the sale of the securities to further our clinical trials and efforts to obtain regulatory approval of Oxycyte, develop our product candidates, including dermatologic indications using our topical gel, support manufacturing of Oxycyte, for research and development and for general corporate purposes, including working capital and potential acquisitions. Our management has broad discretion over how these proceeds are used and could spend the proceeds in ways with which you may not agree. Pending the use of the proceeds in this offering, we will invest them. However, the proceeds may not be invested in a manner that yields a favorable or any return.
As a new investor, you will incur substantial dilution as a result of this offering and future equity issuances, and as result, our stock price could decline.
The offering price is substantially higher than the net tangible book value per share of our outstanding common stock. As a result, based on expectations, estimatesour capitalization as of January 31, 2013, investors converting or exercising Series C Convertible Preferred Stock or warrants for shares of common stock, as the case may be, will incur immediate dilution. In addition to this offering, subject to market conditions and projectionsother factors, it is likely that we will pursue additional financings in the future, as we continue to build our business. In future years, we will likely need to raise significant additional capital to finance our operations and to fund clinical trials, regulatory submissions and the development, manufacture and marketing of other products under development and new product opportunities. Accordingly, we may conduct substantial future offerings of equity or debt securities. The exercise of outstanding options and warrants and future equity issuances, including future public offerings or future private placements of equity securities and any additional shares issued in connection with acquisitions, will result in dilution to investors. In addition, the market price of our common stock could fall as a result of resales of any of these shares of common stock due to an increased number of shares available for sale in the market.
In addition, our board of directors has the authority to establish the designation of additional shares of preferred stock that may be convertible into common stock without any action by our stockholders, and to fix the rights, preferences, privileges and restrictions, including voting rights, of such shares. Any such additional shares of preferred stock may have rights, preferences and privileges senior to those of outstanding common stock, and the issuance and conversion of any such preferred stock would further dilute the percentage ownership of our stockholders.
There is no public market for the Series C Convertible Preferred Stock or warrants to purchase common stock in this offering.
There is no established public trading market for the Series C Convertible Preferred Stock or warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply for listing of the Series C Convertible Preferred Stock or warrants on any securities exchange. Without an active market, the liquidity of the Series C Convertible Preferred Stock or warrants will be limited.

The warrants may not have any value.
The warrants will be exercisable beginning [] and expire on the [] anniversary of the date of this prospectus,issuance at an initial exercise price per share equal to $[]. In the event that our common stock price does not exceed the exercise price of the warrants during the period when the warrants are exercisable, the warrants may not have any value.
Holders of our warrants will have no rights as a common stockholder until they acquire our common stock.
Until you acquire shares of our common stock upon exercise of your warrants, you will have no rights with respect to our common stock. Upon exercise of your warrants, you will be entitled to exercise the rights of a common stockholder only as to matters for which represent Oxygen Biotherapeutics’ expectations or beliefs, including but not limited to, statements concerning its operations, economic performance, financial condition, and future operational plans. For this purpose, any statements contained herein that are not statements of historical factthe record date occurs after the exercise date.
If we cannot meet the NASDAQ Capital Market continued listing requirements, the common stock underlying the Series C Convertible Preferred Stock may be deemeddelisted which could have an adverse impact on the liquidity and market price of our common stock.
While the shares of common stock underlying the Series C Convertible Preferred Stock and warrants will be listed on NASDAQ, there can be no assurance that they will continue to be forward-looking statements. Without limitinglisted in the generalityfuture. Continued listing of the foregoing, words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intent,” “could,” “estimate,” “might,” “plan,” “predict” or “continue” or the negative or other variations thereof or comparable terminology are intended to identify forward-looking statements. This information may involve known and unknown risks, uncertainties and other factorsa security on NASDAQ is conditioned upon compliance with various continued listing standards, which may cause our actual results, performance or achievements to be materially different from the future results, performance or achievements expressed or implied by any forward-looking statements.

This prospectus contains forward-looking statements, many assuming that Oxygen Biotherapeutics secures adequate financing and is able to continue as a going concern, including statements regarding,require, among other things, (a) Oxygen Biotherapeutics’ plansthat for clinical trials30 consecutive trading days (i) the closing minimum bid price for our listed securities not be lower than $1.00 per share and (ii) our market capitalization not be lower than $35 million. The closing bid price for our shares has been less than $1.00 per share since August 21, 2012 and our market capitalization has been less than $35 million since August 8, 2012.

On September 20, 2012 we received a deficiency notice from NASDAQ due to our market capitalization falling below $35 million for 30 consecutive days. We were required to regain compliance with continued listing standards before March 19, 2013. On October 3, 2012 we received a deficiency notice from NASDAQ due to the closing bid price for our shares falling below $1.00 per share for 30 consecutive days. We are required to regain compliance with continued listing standards before April 1, 2013.
However, we were not able to regain compliance with the market capitalization requirement by March 19, 2013. As a result NASDAQ notified us by letter dated March 20, 2013 of the Staff’s decision to delist our securities from NASDAQ. The letter provides that, unless we request an appeal of this determination, trading of our common stock will be suspended at the opening of business on Oxycyte, (b) Oxygen Biotherapeutics’ plans for obtaining regulatory approvalsApril 1, 2013, and a Form 25-NSE will be filed with the Securities and Exchange Commission to advance testingremove our securities from listing and commercialization of Oxycyte, (c) Oxygen Biotherapeutics’ plans for other product opportunities, (d) Oxygen Biotherapeutics’ view of its industryregistration on NASDAQ. We intend to appeal the Staff’s determination by requesting a hearing before a NASDAQ Listing Qualifications Panel to seek continued listing pending our return to compliance. While the appeal is pending, our securities will not be delisted and the opportunities for its products in that industry, (e) Oxygen Biotherapeutics’ future financing plans and anticipated need for working capital, (f) the impact of governmental regulation, and (g) the potential impact of future technological developments.

RISK FACTORS

The following is a discussion of risks we believe to be significant with respect to our business, operations, financial condition, and other matters pertaining to an investment in our common stock. It is not possible to anticipatecontinued listing or predict every risk that may, in the future, prove to have a significant affect on Oxygen Biotherapeutics. Additional risks, including those that are currently not known to us or that we currently deem immaterial, may also impair our prospects and business operations.

Risks related to our business

We will need to generate income, or raise additional capital to continue our business.

We will need to raise substantial amounts of additional capital to complete the clinical testing of Oxycyte and, if approved for commercial use, establish commercial production of Oxycyte. In addition, we will require funding to pursue development of our wound treatment applications and Fluorovent, and to cover our ongoing administrative and corporate obligations. Our future capital requirements will depend on many factors, including the scope and results of our clinical trials, the timing and outcome of regulatory reviews, administrative and legal expenses, the status of competitive products, the establishment of manufacturing capacity, and the establishment of collaborative relationships. We cannot ensure that this additional funding will be available or, if it is available, that it can be obtained on terms and conditions we find acceptable.

As a result of the foregoing circumstances our independent registered public accounting firm has, and is likely in the future to, include an explanatory paragraph in their audit opinions based on uncertainty regarding our ability to continue as a going concern. An audit opinion of this type may interfere with our ability to obtain debt or equity financing. Any additional funding derived from the sale of equity securities may result in significant dilution to our existing stockholders.

We are limited in the number of products we can pursue so our future depends on our success with a small number of product opportunities.

We have limited financial resources, so at present we are using these resources on developing our Oxycyte oxygen carrier product and to begin the process of developing our potential wound treatment applications. We have halted development on Fluorovent, our oxygen carrying liquid, until we find a license partner willing to pursue development or obtain additional financing to pursue development ourselves. We licensed our implantable glucose sensor to a third party for further development, so how that product may progress is, to a large extent, outside of our control. At present we intend to commit most of our resources to advancing Oxycyte to the point it receives regulatory approval for one or more medical uses, and if this effort is unsuccessful we may not have resources to pursue development of our other products and our business would terminate. Furthermore, by delaying development of Fluorovent, this technology may become obsolete by the time we have sufficient capital to resume development and testing, so the funds expended on this product to date would be lost, as well as our opportunity to benefit if the product could be successfully developed.

We are required to conduct additional clinical trials in the future, which are expensive and time consuming, and the outcome of the trials is uncertain.

We completed Phase I clinical trials on Oxycyte in December 2003, and completed Phase II-A clinical testing in the fourth quarter of 2004 with filings completed in the second quarter of 2008. If we are successful with our Phase II-B trials (of which there is no assurance) we will need to conduct Phase III trials. All of these clinical trials and testing will be expensive and time-consuming and the timing of the FDA review process is uncertain. Our lack of capital over the past two years has prevented us from advancing our clinical testing the way we would have preferred resulting in delays in advancing the testing of Oxycyte. The FDA or we may in the future suspend clinical trials at any time if it is believed that the subjects participating in such trials are being exposed to unacceptable health risks. We cannot ensure that we will be able to complete our clinical trials successfullyregain compliance with NASDAQ listing standards within the time periods established by NASDAQ, or obtain FDA approval of Oxycyte, or that FDA approval, if obtained, will not include limitations on the indicated uses for which Oxycyte may be marketed. Our business, financial condition and results of operations are critically dependent on obtaining capital to advance our testing program and receiving FDA approval of Oxycyte. A significant delay in our planned clinical trials or a failure to achieve FDA approvalat all. Delisting from NASDAQ would have a material adverse effect onnegatively impact us and could result in major setbacks, up to the cessation of our business.

Our activities are and will continue to be subject to extensive government regulation, which is expensive and time consuming, and we won’t be able to sell our product without regulatory approval.

Our research, development, testing, manufacturing, marketing and distribution of products are, and will continue to be, subject to extensive regulation, monitoring and approvalstockholders by, the FDA. There are significant risks at each stage of the regulatory scheme.

Product approval stage

During the product approval stage we attempt to prove the safety and efficacy of our product for its indicated uses. There are numerous problems that could arise during this stage, including:

The data obtained from laboratory testing and clinical trials are susceptible to varying interpretations, which could delay, limit or prevent FDA regulatory approval.

The lack of established criteria for evaluating the effectiveness of blood substitute products could delay or prevent FDA regulatory approval.

At any time the FDA could change policies and regulations that could result in delay and perhaps rejection of our products.

Even after extensive testing and clinical trials, there is no assurance regulatory approval will ever be obtained for any of our products.

Commercialization approval stage

We will be required to file a Biologics License Application, or BLA, with the FDA in order to obtain regulatory approval for the commercial production and sale of Oxycyte in the United States. Under FDA guidelines, the FDA may comment upon the acceptability of a BLA following its submission. After a BLA is submitted there is an initial review by the FDA to be sure that all of the required elements are included in the submission. There can be no assurance that the submission will be accepted for filing or that the FDA may not issue a refusal to file, or RTF. If an RTF is issued, there is opportunity for dialogue between the sponsor and the FDA in an effort to resolve all concerns. There can be no assurance that such a dialogue will be successful in leading to the filing of the BLA. If the submission is filed, there can be no assurance that the full review will result in product approval.

Post-commercialization stage

Discovery of previously unknown problems with Oxycyte or another product, or unanticipated problems with our manufacturing arrangements, even after FDA approval of Oxycyte or another product for commercial sale, may result in the imposition of significant restrictions, including withdrawal of the product from the market.

Additional laws and regulations may also be enacted that could prevent or delay regulatory approval of Oxycyte or our other products, including laws or regulations relating to the price or cost-effectiveness of medical products. Any delay or failure to achieve regulatory approval of commercial sales of our products is likely to have a material adverse effect on our financial condition.

The FDA continues to review products even after they receive agency approval. If and when the FDA approves one of our products, its manufacture and marketing will be subject to ongoing regulation, including compliance with current good manufacturing practices, adverse event reporting requirements and the FDA’s general prohibitions against promoting products for unapproved or “off-label” uses. We are also subject to inspection and market surveillance by the FDA for compliance with these and other requirements. Any enforcement action resulting from failure, even by inadvertence, to comply with these requirements could affect the manufacture and marketing of Oxycyte. In addition, the FDA could withdraw a previously approved product from the market upon receipt of newly discovered information. The FDA could also require us to conduct additional, and potentially expensive, studies in areas outside our approved indicated uses.

We are a development stage company without revenues or profits, which raises doubt about our ability to continue as a going concern.

Oxygen Biotherapeutics began research and development activities in 1990 and is a development stage company. We have been engaged for the past 18 years in the development and testing of Oxycyte, Fluorovent, and our glucose biosensor. No revenues have been generated to date from commercial sales of any of our products. Our revenues to date have consisted solely of interest earned on funds held until applied in the development of our products. At July 31, 2008 our accumulated deficit during the development stage is $41,989,577. We will require substantial amounts of outside financing to fund future testing and development of our products. We cannot ensure that our clinical testing will be successful, that regulatory approval of Oxycyte or any of our other products will be obtained, that Oxycyte or any of our other products can be manufactured at an acceptable cost and in appropriate quantities, or that there will be a viable market for any of our products. The foregoing factors raise substantial doubt about our ability to continue as a going concern.

Presently we are focusing on developing Oxycyte, which is subject to a high level of technological risk.

We completed Phase I clinical trials on Oxycyte in December 2003, and we expect we will devote a substantial portion of our financial and managerial resources to pursuing Phase II and Phase III clinical trials on this product over the next three years. As our other products are not as far along in the development and approval process as Oxycyte, our opportunity to generate product revenues within the next four to five years is most likely dependent on successful testing and commercialization of Oxycyte for surgical and similar oxygen delivery applications. The biomedical field has undergone rapid and significant technological changes. Technological developments may result in Oxycyte becoming obsolete or non-competitive before we are able to recover any portion of the research and development and other expenses we have incurred to develop and clinically test Oxycyte. Any such occurrence would have a material adverse effect on our operations and could result in the cessation of our business.

We are not certain that we will be able to manufacture Oxycyte commercially.

Commercial-scale manufacturing of Oxycyte will require development of a manufacturing capability that is significantly larger than the capacity currently in place to produce Oxycyte for our clinical trials. We do not intend to build our own production facility, but instead will rely on third party manufacturers to produce our product. We are currently in the process of establishing an arrangement for commercial production of Oxycyte with a manufacturer in North Carolina, but there can be no assurance that we will be able to establish such an arrangement on terms acceptable to us. Moreover, in order to seek FDA approval of the sale of Oxycyte produced at a third party manufacturing facility, we may be required to conduct a portion of our clinical trials with product manufactured at that facility. Accordingly, a delay in achieving scale-up of commercial manufacturing capabilities when needed will have a material adverse effect on sales of Oxycyte. Additionally, the manufacture of Oxycyte will be subject to extensive government regulation. Among the conditions for marketing approval is that our quality control and manufacturing procedures conform to the FDA’s good manufacturing practice regulations. We cannot ensure that we will be able to obtain the necessary regulatory clearances or approvals to manufacture Oxycyte on a timely basis or at all.

There are significant competitors developing similar products.

If approved for commercial sale, Oxycyte will compete directly with established therapies for oxygen delivery, and acute blood loss and may compete with other technologies currently under development. We cannot ensure that Oxycyte will have advantages, which will be significant enough to cause medical professionals to adopt it rather than continue to use established therapies or to adopt other new technologies or products. We also cannot ensure that the cost of Oxycyte will be competitive with the cost of established therapies or other new technologies or products. The development of blood substitute products is a rapidly evolving field. As there is currently no oxygen delivery product of our kind on the market, competition to develop an efficacious and accepted product is intense. Several companies have developed or are in the process of developing technologies that are, or in the future may be, the basis for products that will compete with Oxycyte. Certain of these companies are pursuing different approaches or means of accomplishing the therapeutic effects sought to be achieved through the use of Oxycyte.

These companies and others have substantially greater financial resources, larger research and development staffs, more extensive facilities and more experience than Oxygen Biotherapeutics in testing, manufacturing, marketing and distributing medical products. We cannot ensure that one or more other companies will not succeed in developing technologies or products that will become available for commercial use prior to Oxycyte, which could be more effective or less costly than Oxycyte or would render Oxycyte obsolete or non-competitive.

We do not have experience in the sale and marketing of medical products.

We have no experience in the sale or marketing of medical products. We have not decided upon a marketing strategy. We do not know of any third party that is prepared to distribute Oxycyte should it be approved. If we decide to establish our own marketing capability, we will need to recruit, train and retain a marketing staff and sales force with sufficient technical expertise. We do not know whether we can establish a marketing program at a cost that is acceptable in relation to revenue or whether we can be successful in marketing our product. Failure to successfully market Oxycyte or to do so on a cost effective basis would likely result in failure of our business.

We have a history of losses and our future operating results are uncertain.

During fiscal year ended April 30, 2008, we incurred a net loss of $6.7 million, and we incurred a net loss of $3.3 million in fiscal year 2007. Our net loss for the three-month period ended July 31, 2008, was $4.2 million. We will not generate operating revenue unless and until one of our products is approved for commercial sale and sales activity begins. We will require substantial additional funds to complete clinical trials, pursue regulatory approval for our products, establish commercial scale manufacturing capabilities, and establish marketing, sales, and administrative capabilities. Expenditures for these purposes will result in substantial losses for at least the next several years. The expense and the time required to realize any product revenues or profitability are highly uncertain. We cannot ensure that we will be able to achieve product revenues or profitability on a sustained basis, or at all, and we may be unable to ever establish Oxygen Biotherapeutics as a going concern.

The market may not accept our product.

Human blood collection, distribution, and medical application are well established and accepted. Competitors may develop new technologies or products, which are effective, competitively priced, and accepted for various medical uses. We cannot ensure that the efficacy and pricing of Oxycyte, considered in relation to Oxycyte’s expected benefits, will be perceived by health care providers and third party payers as cost-effective, or that the price of Oxycyte will be competitive with transfused blood or with other new technologies or products. Our results of operations may be adversely affected if the price of Oxycyte is not considered cost-effective or if Oxycyte does not otherwise achieve market acceptance.

Our patents and other proprietary rights may not protect our technology.

Our ability to compete effectively with other companies will depend, in part, on our ability to protect and maintain the proprietary nature of our technology. We cannot be certain as to the degree of protection offered by our patents or as to the likelihood that additional patents in the United States and certain other countries will be issued based upon pending patent applications. Patent applications in the United States are maintained in secrecy until patents are issued. We cannot be certain that we were the first creator of the inventions covered by our patents or pending patent applications or that we were the first to file patent applications for our inventions. The high costs of enforcing patent and other proprietary rights may also limit the degree of protection afforded to us. We also rely on unpatented proprietary technology, and we cannot ensure that others may not independently develop the same or similar technology or otherwise obtain access to our proprietary technology. We cannot ensure that our patents or other proprietary rights will be determined to be valid or enforceable if challenged in court or administrative proceedings or that we will not become involved in disputes with respect to the patents or proprietary rights of third parties. An adverse outcome from these proceedings could subject us to significant liabilities to third parties, require disputed rights to be licensed from third parties, or require us to stop using this technology, any of which would result in a material adverse effect on our results of operations.

Our viability will be affected if we incur product liability claims in excess of our insurance coverage.

The testing and marketing of medical products, even after FDA approval, have an inherent risk of product liability. We maintain limited product liability insurance coverage for our clinical trials in the total amount of $3 million. However, our profitability will be adversely affected by a successful product liability claim in excess of our insurance coverage. We cannot guarantee that product liability insurance will be available in the future or be available on reasonable terms.

We depend on the services of a limited number of key personnel.

Our success is highly dependent on the continued services of a limited number of scientists and support personnel. The loss of any of these individuals could have a material adverse effect on us. In addition, our success will depend, among other factors, onthings, reducing the recruitmentliquidity and retention of additional highly skilled and experienced management and technical personnel. We cannot ensure that we will be able to retain existing employees or to attract and retain additional skilled personnel on acceptable terms given the competition for such personnel among numerous large and well-funded pharmaceutical and health care companies, universities, and non-profit research institutions.

Health care reform and controls on health care spending may limit the price we can charge for Oxycyte and the amount we can sell.

The federal government and private insurers have considered ways to change, and have changed, the manner in which health care services are provided in the United States. Potential approaches and changes in recent years include controls on health care spending and the creation of large purchasing groups. In the future, it is possible that the government may institute price controls and limits on Medicare and Medicaid spending. These controls and limits might affect the payments we collect from sales of our product. Assuming we succeed in bringing Oxycyte to market, uncertainties regarding future health care reform and private market practices could affect our ability to sell Oxycyte in large quantities at profitable pricing.

Uncertainty of third-party reimbursement could affect our future profitability.

Sales of medical products largely depend on the reimbursement of patients’ medical expenses by governmental health care programs and private health insurers. There is no guarantee that governmental health care programs or private health insurers will reimburse our sales of Oxycyte, or permit us to sell our product at high enough prices to generate a profit.

Use of Proceeds
Assuming all units are sold, we estimate that the net proceeds to us from this offering will be approximately $[] million. This amount does not include the proceeds which we may receive in response to aconnection with the exercise of the warrants. We cannot predict when or if the warrants will be exercised, and it is possible that the warrants may expire and never be exercised. The offering does not specify any minimum sale of any specific number of factors, many of which are beyond our control, including:

Regulatory developments relating to our Oxycyte oxygen carrier product;

Announcementsunits and, as a result, the net proceeds actually received by us relatingmay be considerably less than the estimated net proceeds above.

We intend to use the resultsnet proceeds of this offering to further our clinical trials of Oxycyte;

Developments relating to ourand efforts to obtain additional financing to fund our operations;

Announcements by us regarding transactions with potential strategic partners;

Announcements relating to oxygen carrier, or blood substitute products being developed by our competitors;

Changes in industry trends or conditions;

Our issuance of additional debt or equity securities; and

Sales of significant amounts of our common stock or other securities in the market.

In addition, the stock market in general, and the over-the-counter market and the biotechnology industry market in particular, have experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of other public companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our company specific results.

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

The authorized capital stock of Oxygen Biotherapeutics consists of an aggregate of 400 million shares of common stock, of which 159,761,386 shares are issued and outstanding as of October 8, 2008 and approximately 211,244,408 million shares are reserved for issuance upon conversion or exercise of issued and outstanding notes, options, and warrants. The substantial number of shares available now and that may become available in the future for sale in the public market could cause the market price of our common stock to decline or have a depressive effect on the market price.

As we complete additional equity financings in the future, the existing shareholders will experience dilution.

As noted above, we will need to raise substantial amounts of additional capital to complete the clinical testing of Oxycyte and, if approved for commercial use, establish commercial production of Oxycyte. We will seek and pursue both equity and debt financing opportunities to fund our working capital requirements in the future. Any additional equity financing that we obtain would have the effect of diluting the ownership interest of existing shareholders.

OUR BUSINESS

General

Oxygen Biotherapeutics, Inc. is engaged in the business of developing biotechnology products with a focus on oxygen delivery to tissue. We are currently developing Oxycyte™, a product we believe is a safe and effective alternative to transfused blood for use in surgical and similar medical situations. We are pursuing application of the same perfluorocarbon oxygen carrier technology to development of topical wound healing therapies. We also have under development Fluorovent™, an oxygen exchange fluid for facilitating the treatment of lung conditions. We recently licensed to a third party for development our biosensor implant product that uses an enzyme process for measuring the glucose level in subcutaneous fluid.

We received approval of our Investigational New Drug application for Oxycyte filed with the U.S. Food and Drug Administration (FDA) and began Phase I clinical studies in October 2003, which were completed in December 2003. We submitted a report on the results, which were in line with our expectations, to the FDA along with a Phase II protocol in 2004. Phase II-A clinical studies began in the fourth quarter 2004, and were completed in 2006. A further Phase II study protocol was filed with the FDA in the spring of 2008. Management is hopeful the protocol will be approved and the new study begun in 2008, and if this comes to pass the study would continue into 2009. We expect to commit a substantial portion of our financial and business resources over the next three years to testing Oxycyte and advancing this product to the point it has regulatory approval for use in one or more medical applications. While pursuing Oxycyte, we are increasing our focus on a new application of perfluorocarbon oxygen carrier technology to therapies applied to the skin, rather than infused, for treating wounds and abrasions. To that end we recently licensed certain technology related that application from Virginia Commonwealth University and engaged the services of an independent consultant to pursue research and development of the therapies.

Fluorovent is still at the animal testing stage and we have not filed any applications with the FDA for human testing of this product. Since we will likely devote less of our time and resources to advancing this product because of the priority placed on Oxycyte and topical therapies, we do not expect we will be in a position to file any application for this product with the FDA in the near future. Since our priority for the foreseeable future is Oxycyte and topical wound therapy, the following discussion of our business focuses primarily on those products.

Our biosensor implant is still at the animal testing stage and we have not filed any applications with the FDA for human testing. Since we do not expect to commit significant resources to development of this technology in the foreseeable future, we recently licensed the technology to an unrelated party who is more focused on research and development in the area of glucose testing and related technologies.

Oxygen Biotherapeutics was originally formed as a New Jersey corporation in 1967 under the name Rudmer, David & Associates, Inc., and subsequently changed its name to Synthetic Blood International, Inc. On June 17, 2008, the stockholders of Synthetic Blood International approved the Agreement and Plan of Merger dated April 28, 2008, between Synthetic Blood International and Oxygen Biotherapeutics, Inc., a Delaware corporation. Oxygen Biotherapeutics was formed on April 17, 2008, by Synthetic Blood International to participate in the merger for the purpose of changing the state of domicile of Synthetic Blood International, Inc. from New Jersey to Delaware. Certificates of Merger were filed with the states of New Jersey and Delaware, and the merger was effective June 30, 2008. Under the Plan of Merger, Oxygen Biotherapeutics, Inc. is the surviving corporation and each share of Synthetic Blood International, Inc. common stock outstanding on June 30, 2008, was converted to one share of Oxygen Biotherapeutics, Inc. common stock.

Oxygen to Tissue Delivery Market

The principal function of human blood is to transport oxygen throughout the body. The lack of an adequate supply of oxygen as a result of blood loss can lead to organ dysfunction or death. The transfusion of human blood is presently the only effective means of immediately restoring diminished oxygen-carrying capacity resulting from blood loss. According to the AABB 2005 Nationwide Blood Collection and Utilization Report, over 14 million units of whole blood and red blood cells were transfused in the United States in 2004. This includes transfusions for trauma, surgery (emergency and elective), unexpected blood loss, chronic anemia, and other general medical applications.

The use of donated blood in transfusion therapy, while effective in restoring an adequate supply of oxygen in the body of the recipient, has several limitations. Although testing procedures exist to detect the presence of certain diseases in blood, these procedures cannot eliminate completely the risk of blood-borne disease. Transfused blood also can be used only in recipients having a blood type compatible with that of the donor. Delays in treatment, resulting from the necessity of blood typing prior to transfusion, together with the limited shelf life of blood and the limited availability of certain blood types, impose constraints on the immediate availability of compatible blood for transfusion. There is no commercially available blood substitute in this country that addresses these problems.

Oxycyte is intended as an oxygen carrier and substitute for blood transfusion that ordinarily would be applied in cases of trauma, surgery (emergency and elective), unexpected blood loss and other general medical applications. For trauma and emergency surgical procedures, the immediate availability and universal compatibility of Oxycyte are expected to provide significant advantages over transfused blood, because we believe Oxycyte is capable of transporting higher levels of oxygen than red blood cells are able to transport.

We believe there exist potential sources of demand for which blood is not currently utilized and for which Oxycyte may be suitable. These include applications in which the required blood type is not immediately available or in which transfusions are desirable but not given for fear of a transfusion reaction due to difficulty in identifying compatible blood. For example, we believe emergicenters and surgicenters both experience events where an oxygen-carrying fluid may be useful. We also believe Oxycyte may be used by emergency medical technicians in ambulances, medical helicopters and other pre-hospital settings. In addition, the military has expressed a high level of interest in oxygen-carrying products for the resuscitation of battlefield casualties.

Based on these circumstances, we believe there may be a substantial and meaningful market for an effective oxygen carrier, and we believe Oxycyte is a viable candidate for exploiting that market.

Our primary product—Oxycyte

Our Oxycyte oxygen carrier product is a perfluorocarbon emulsified with water and a surfactant, which is provided to the patient intravenously. The physical properties of perfluorocarbon enable our product to gather oxygen from the lungs and transport the oxygen through the body releasing it along the way. Over a period of days Oxycyte gradually evaporates in the lungs from where it is

exhaled. Oxycyte requires no cross matching, so it is immediately available and compatible with all blood types. Oxycyte has an extended shelf life compared to blood. Since Oxycyte is not based on any biological component, it is sterile and free of potential contamination from a donor. Further, since Oxycyte is based on readily available inert compounds, we believe it can be manufactured on a cost effective basis in amounts sufficient to meet demand.

After receiving clearance from the FDA, we conducted a Phase I clinical study on Oxycyte, which was completed in December 2003. We submitted a report on the results, which were in line with our expectations, to the FDA along with a Phase II protocol in 2004. Phase II-A clinical studies began in the fourth quarter 2004, and were completed in 2006. A further Phase II study protocol was filed with the FDA in the spring of 2008. Management is hopeful the protocol will be approved and the new study begun in 2008, and if this comes to pass the study would continue into 2009.

We use a proprietary process of perfluorocarbon production and emulsification to produce Oxycyte. We use a contract manufacturer to produce Oxycyte for our clinical testing. Our contract manufacturer for trial batches is PrimaPharm, Inc. located in San Diego, California. Based on production testing and inspection, the FDA has determined that PrimaPharm satisfies its good manufacturing practices standards with respect to the production of Oxycyte. Based on the composition and manufacturing process for Oxycyte, management believes there are a number of other manufacturers capable of producing Oxycyte in accordance with FDA regulations and in sufficient quantities for current needs. For larger batches we intend to employ the contract manufacturing services of a major pharmaceutical company in North Carolina.

Should Oxycyte successfully progress through Phase II and III testing and it appears regulatory approval for one or more medical uses is likely, we will evaluate our options for realizing revenue on the product. These options include licensing Oxycyte to a third party for manufacture and distribution, manufacturing Oxycyte ourselves for distribution through third party distributors, manufacturing and selling the product ourselves, or establishing some other form of strategic relationship for making and distributing Oxycyte with a participant in the pharmaceutical industry. We are currently investigating and evaluating all options.

If approved for one or more medical uses, Oxycyte will compete directly with established therapies for acute blood loss and replacement and may compete with other technologies currently under development. We cannot ensure that Oxycyte will have advantages, which will be significant enough to cause medical professionals to adopt it rather than continue to use established therapies or other new technologies or products. We also cannot ensure that the price of Oxycyte, in light of Oxycyte’s potential advantages, will be competitive with the price of established therapies or other new technologies or products.

Several companies have developed or are in the process of developing technologies that are, or in the future may be, the basis for products that will compete with Oxycyte. We are aware of five other products at various stages of development that are intended to achieve the same result as Oxycyte. Three of these products are based on hemoglobin derivates, two from outdated human blood and the third from bovine blood. One product is also based on perfluorocarbon and the other on nanobubble oxygen technology. None of these products is approved for use in the United States. The bovine-source hemoglobin-based oxygen-carrier has been approved for human use in South Africa and a Biologics License Application, or BLA, was submitted to the FDA for its use in the United States, and it was not approved and no clinical trials in the United States are currently underway. All hemoglobin based products were targets of a very critical meta-analysis in the JAMA, the Journal of the American Medical Association, (May 21, 2008, p. 2304ff,www.jama.com) which concluded that “based on the available data, use of HBBSs (Hemoglobin-based blood substitutes) is associated with a significantly increased risk of death or MI (myocardial infarction)”. Phase III clinical trials on the other perfluorocarbon product in the U.S. were halted in 2001 and have not resumed. That product has now been licensed for development with a drug manufacturer in China.

We believe that important competitive factors in the market for oxygen carrier products will include the relative speed with which competitors can develop their respective products, complete the clinical testing and regulatory approval process, and supply commercial quantities of their products to the market. In addition to these factors, competition is expected to be based on the effectiveness of oxygen carrier products and the scope of the intended uses for which they are approved, the scope and enforceability of patent or other proprietary rights, product price, product supply, and marketing and sales capability. We believe that our competitive position will be significantly influenced by the timing of the clinical testing and regulatory filings for Oxycyte, our ability

to maintain and enforce our proprietary rights covering Oxycyte and its manufacturing process, and our ability to develop capabilities for manufacturing and distributing the product ourselves or with others, should we obtain regulatory approval.

Our other products

Wound Treatment Applications

In May 2008, we entered into a license agreement with Virginia Commonwealth University whereby we acquired a worldwide, exclusive license to three of the University’s patent applications that relate to methods for non-pulmonary delivery of oxygen to tissue and the products based on those patent applications. We obtained the license to use the technology in conjunction with our Oxycyte technology to develop over-the-counter and clinical treatment applications that are used externally to treat wounds, abrasions and burns.

According to the National Institute of General Medical Sciences, more than 36 million topical wounds are treated every year. The wound care product market is projected to reach $12.5 billion by 2012. It is clear there is a substantial market for products that are efficacious in treating these injuries, and we believe the new applications we are now pursuing show promise for meeting the product needs of that market. Our objective is to develop products that are an improvement over existing technology by producing a better healing result, shortening the healing process, and/or mitigating complications.

Our license with Virginia Commonwealth University if for a term equal to the life of the patents covered by the patent applications, except that we can terminate the agreement at any time on not less than 90 days advance notice. It includes the right to sub-license to third parties. We have an obligation to diligently pursue product development and pursue, at our expense, prosecution of the patent applications covered by the agreement. We paid an initial fee of $50,000 in cash and paid an additional $16,288 to the Licensor as reimbursement of costs paid by the Licensor on patent applications and related work. We also issued to the licensor a warrant for the purchase of 500,000 shares of our restricted common stock at an exercise price of $0.42 per share that expires May 22, 2013. We agreed to pay to the Licensor a running royalty on net sales of licensed products equal to 25% of the first $10 million of net sales, 15% of the next $39 million of net sales and 10% of net sales over $49 million. We also agreed to pay to the University a percentage of sublicensing revenue received from sub-licensees or other third parties in regards to the licensed patent rights equal to 33% of any such third party payments, which may be reduced to 25% if we complete pre-clinical studies on a licensed product, reduced further to 20% if we complete Phase I clinical studies, reduced further to 17% if we complete Phase II clinical studies, and reduced further to 10% if we complete Phase III clinical studies on a licensed product. We agreed to pay the University a $20,000 annual maintenance fee and $50,000 annual minimum royalty starting in May 2009 as long as the agreement is in force. We are entitled to credit the maintenance fee and minimum royalty payments against future royalty or sublicensing revenue payments to the University under the license agreement. Finally, we agreed to make certain regulatory milestone payments to the University up to a maximum of $275,000 for each product that goes through the medical device application and marketing approval process, and up to a maximum of $1,125,000 for each product that goes through the clinical trial and marketing approval process.

To facilitate development of wound treatment products, we entered into a consulting agreement with Robert F. Diegelmann, Ph.D., Professor of Biochemistry, Anatomy and Emergency Medicine at Virginia Commonwealth University Medical Center. Dr. Diegelmann has agreed to conduct research, advance development, and assist with permitting for topical wound-healing therapies. The agreement is for a term of three years, and we agreed to pay Dr. Diegelmann $9,000 per month for his services. The agreement also provides for additional incentive compensation. Upon successful registration of a 510K application for the first product, the agreement provides we will issue to Dr. Diegelmann an option to purchase 100,000 common shares under our stock plan. In addition, we agreed to pay Dr. Diegelmann a success fee equal to one percent of net revenue from our direct product sales. If we sell or license the product rights to a third party we agreed to pay Dr. Diegelmann a transaction fee based on the aggregate consideration we receive equal to five percent of the first $1,000,000, four percent of the next $1,000,000, three percent of the next $1,000,000, two percent of the next $1,000,000 and one percent for each $1,000,000 of consideration above $4,000,000 up to a maximum of $250,000.

Fluorovent

Fluorovent is an oxygen-carrying perfluorocarbon liquid that, when dispensed directly into the lungs, acts as a surfactant and effective medium for gas exchange, which increases pulmonary function and the diffusion of oxygen and carbon dioxide through the

lungs into the body. The development of this product capability has applications in the treatment of acute lung disease, such as infant respiratory distress syndrome and adult respiratory syndrome. Further development of this product is currently on hold, until we have found a partner to bring this product to market.

Implanted glucose biosensor

We have developed an implanted glucose biosensor to monitor blood glucose. Termed a biosensor because it utilizes an enzyme specific for glucose, we believe the technology is capable of producing glucose measurement significantly more accurate than possible from current portable measuring devices. On September 22, 2008, we entered into a license agreement with Glucometrics, Inc., an unrelated third party, pursuant to which we licensed the intellectual property pertaining to our biosensor implant product for the development, manufacture, and marketing of products that use or incorporate the intellectual property. In exchange for the license we acquired:

a 10% equity interest in Glucometrics;

the right to receive a royalty payment on implantable products equal to 10% of the first $10 million in net sales, 8% of the next $40 million of net sales, and 6% of net sales equal to or greater than $50 million;

the right to receive a royalty payment on non-implantable products equal to 8% of the first $5 million in net sales, 6% of the next $20 million of net sales, and 4% of net sales equal to or greater than $25 million; and

participation in fees and payments made under sublicensing arrangements.

The term of the license agreement is for the life of the patent right licensed under the agreement.

Our patents and intellectual property

Perfluorocarbon products

We hold four U.S. patents (5,674,913; 5,824,703; 5,840,767; 6,167,887), three Australian patents (690,277; 722,417; 759,557), two Canadian Patents (2,239,170; 2,311,122) and, one European patent (EPO 8697678B1) pertaining to the use and application of perfluorocarbons as gas transport agents in blood substitutes and liquid ventilation. Additionally, the process of manufacturing the perfluocarbon contained in our products is extremely complicated and protected by numerous perfluorocarbon manufacturing process patents of our supplier.

Biosensor

We have three U.S. patents (5,914,026; 5,964,993 6,343,225) and two Australian patents (720,712; 734,003) that protect what we believe are important design features of our implanted glucose biosensor. We also hold exclusive licenses to three fundamental biosensor patents that represent the core technology used on our product. These patent and intellectual property rights were licensed in September 2008, to Glucometrics, Inc.

Government regulation

The manufacture and distribution of Oxycyte, as well as our other products, and the operation of any manufacturing facility we may establish will require the approval of United States government authorities as well as those of foreign countries. In the United States, the FDA regulates medical products, including the category known as “biologicals” which includes Oxycyte. The Federal Food, Drug and Cosmetic Act and the Public Health Service Act govern the testing, manufacture, safety, effectiveness, labeling, storage, record keeping, approval, advertising and promotion of Oxycyte. In addition to FDA regulations, we are also subject to other federal and state regulations, such as the Occupational Safety and Health Act and the Environmental Protection Act. Product development and approval within this regulatory framework requires a number of years and involves the expenditure of substantial funds.

The steps required before a biological product may be sold commercially in the United States include pre-clinical testing, the submission to the FDA of an Investigational New Drug application, clinical trials in humans to establish the safety and effectiveness of the product, the submission to the FDA of a Biologics License Application, or BLA, relating to the product and the manufacturing facilities to be used to produce the product for commercial sale, and FDA approval of a BLA. After a BLA is submitted there is an initial review by FDA to be sure that all of the required elements are included in the submission. There can be no assurance that the

application will be accepted for filing or that the FDA may not issue a refusal to file, or RTF. If an RTF is issued, there is opportunity for dialogue between the sponsor and the FDA in an effort to resolve all concerns. There can be no assurance that such a dialogue will be successful in leading to the filing of the BLA. If the submission is filed, there can be no assurance that the full review will result in product approval.

Pre-clinical tests include evaluation of product chemistry and studies to assess the safety and effectiveness of the product and its formulation. The results of the pre-clinical tests are submitted to the FDA as part of the Investigational New Drug application. The goal of clinical testing is the demonstration in adequate and well-controlled studies of substantial evidence of the safety and effectiveness of the product in the setting of its intended use. The results of pre-clinical and clinical testing are submitted to the FDA from time to time throughout the trial process. In addition, before approval for the commercial sale of a product can be obtained, results of the pre-clinical and clinical studies must be submitted to the FDA in the form of a BLA. The testing and approval process requires substantial time and effort and there can be no assurance that any approval will be granted on a timely basis, if at all. The approval process is affected by a number of factors, including the severity of the condition being treated, the availability of alternative treatments and the risks and benefits demonstrated in clinical trials. Additional pre-clinical studies or clinical trials may be requested during the FDA review process and may delay product approval. After FDA approval for its initial indications, further clinical trials may be necessary to gain approval for the use of a product for additional indications. FDA may also require post-marketing testing, which can involve significant expense, to monitor for adverse effects.

Among the conditions for BLA approval is the requirement that the prospective manufacturer’s quality controls and manufacturing procedures conform to FDA requirements. In addition, domestic manufacturing facilities are subject to biennial FDA inspections and foreign manufacturing facilities are subject to periodic FDA inspections or inspections by the foreign regulatory authorities with reciprocal inspection agreements with FDA. Outside the United States, we are also subject to foreign regulatory requirements governing clinical trials and marketing approval for medical products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country.

Our regulatory strategy is to pursue clinical testing and FDA approval of Oxycyte in the United States. We intend to arrange for testing and seek regulatory approval of Oxycyte, outside the United States through licensing or other arrangements with other foreign or domestic companies. To date, we have not conducted any clinical trialsdevelop our product candidates, including dermatologic indications using our topical gel, support manufacturing of Oxycyte, outsidefor research and development and for general corporate purposes, including working capital and potential acquisitions. We currently do not have any arrangements or agreements for any acquisitions. We cannot precisely estimate the allocation of the United States.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

Overview

Since 1990, Oxygen Biotherapeutics has pursued the development of medical products based on perfluorocarbon technology. These products include Oxycyte™, a synthetic oxygen carrier substance, and Fluorovent™, an oxygen exchange fluid for facilitating the treatment of lung conditions. Since 1993 Oxygen Biotherapeutics has also pursued development of a glucose biosensor implant, which we recently licensed to a third party for development. In September 2008 we engaged a researcher to pursue application of the same perfluorocarbon oxygen carrier technology to development of topical wound healing therapies.

The nature of our business is to spend years in development and testing of pharmaceutical and medical device products, take products through a lengthy and expensive process of regulatory review by the FDA, and, if successful in showing the product is efficacious and obtaining FDA approval, commercialize the product. During the periods of development and regulatory review we have no product to sell and no revenue. Nevertheless, we incur substantial costs pursuing this process, which require cash that comes from outside sources. We rely on outside financing to fund our operations, and will for the foreseeable future. That means we must continue to show progress with our products and be able to locate investors willing to commit their funds to a speculative venture that will ultimately be successful only if we can actually bring a product to market and gain a meaningful level of market acceptance and penetration. Because of these factors a larger number of biotechnology products under development fail, and there is no assurance that the products we have under development will not suffer the same fate.

We received approval of the Investigational New Drug application we filed with the FDA on Oxycyte and began Phase I clinical tests in October 2003. We completed the clinical tests in December 2003. The results of the Phase I tests were in line with our safety and efficacy expectations for the performance of Oxycyte. We started Phase II testing in 2004.

Five clinical sites have received local Institutional Review Board (IRB) approval to participate in the first Phase II trial with Oxycyte in hip surgery patients. In this first Phase II trial we were evaluating both efficacy and safety in the prevention of tissue hypoxia (the effects of reduced oxygen levels) in hip surgery patients who experience mild to moderate blood loss during surgery. While blood transfusions are typically not given during such procedures, blood loss may result in postoperative complications caused by tissue hypoxia. We closed this study in 2006 due to a lack of enrollment and completed this study and reported our findings in April 2008.

A Phase II-A trial in severe brain injury patients was started in 2006 and has been completed with good results. The Phase II-B trial protocol was filed in April 2008 and is currently under review of the FDA. A revised Phase II protocol for a study in patients with sickle cell pain crisis is ready to be filed with the FDA, as soon as the severe brain injury Phase II-B trial has been approved. Our future plans include testing Oxycyte in stroke, myocardial infarction, malignant tumors, trauma, coronary bypass surgery and decompression sickness. We expect Phase II studies will continue over at least the next two years, after which Phase III studies may be able to commence depending on results of Phase II trials, the development of acceptable protocols for Phase III trials, and the availability of financial and other resources to pursue the Phase II trials.

While pursuing Oxycyte, we are increasing our focus on a new application of perfluorocarbon oxygen carrier technology to therapies applied to the skin, rather than infused, for treating wounds and abrasions. To that end we recently licensed certain technology related that application from Virginia Commonwealth University and engaged the services of an independent consultant to pursue research and development of the therapies.

Fluorovent is still at the animal testing stage and we have not filed any applications with the FDA for human testing of this product. Since we will likely devote less of our time and resources to advancing this product because of the priority placed on Oxycyte and topical therapies, we do not expect we will be in a position to file any application for this product with the FDA in the near future. Since our priority for the foreseeable future is Oxycyte and topical wound therapy, the following discussion of our business focuses primarily on those products.

Our biosensor implant is still at the animal testing stage of development and we have not filed any applications with the FDA for human testing. Since we do not expect to commit significant resources to development of this technology in the foreseeable future, we recently licensed the technology to an unrelated party who is more focused on research and development in the area of glucose testing and related technologies.

Results of operations

Quarter ended July 31, 2008 compared to quarter ended July 31, 2007

Research and Development expenses for the three months ended July 31, 2008 were $308,288, compared to $151,492 for the same period in the prior year. Due to the financing we obtained during the third and fourth quarters of fiscal 2008, we were able to resume funding of our Phase II clinical trials and increase our laboratory supplies and related expenses. Phase II expenses totaled $49,071 for the quarter ended July 31, 2008, compared to $800 for the quarter ended July 31, 2007. Laboratory supplies totaled $34,553 during the quarter ended July 31, 2008, compared to $917 during the quarter ended July 31, 2007. Consulting fees for our clinical studies totaled $20,570 during the quarter ended July 31, 2008, compared to $0 during the quarter ended January 31, 2007. Additionally, we incurred $19,700 in contract manufacturing costs for Oxycyte and $14,755 of equipment rental costs in the current quarter that we did not incur in the quarter ended July 31, 2007. Because of the nature of our ongoing research and development activities and depending on our cash flow levels, accounting periods may reflect significant changes in expenses resulting from the timing of research related to our developmental products.

General and Administrative expenses for the three months ended July 31, 2008 were $2,818,581, compared to $213,486 for the same period in the prior year. During the current quarter we incurred $2,168,202 of consulting fees that we did not incur during the same period in the prior year. Of this $2,168,202 total, $1,874,932 was non-cash expense through the issuance of common stock purchase warrants. Our contract management costs increased by $149,799 in the current quarter, and this change is primarily due to our current Chief Executive Officer being compensated as an independent contractor, and an increase in consulting fees paid to two of our non-officer directors. Other significant changes in our administrative expenses during the quarter ended July 31, 2008 included a $56,694 increase in our noncash compensation relating to the issue of compensatory stock options, a $51,161 increase in our administrative payroll, an $83,117 increase in our investor relations, a $41,020 increase in our accounting expenses and a $27,653 increase in our legal expenses over the amounts incurred during the quarter ended July 31, 2007.

The net loss for the three months ended July 31, 2008 was $4,248,215 compared to a net loss of $1,027,227 for the same period in the prior year. Total operating expenses increased $2,761,891 during the quarter ended July 31, 2008 over the comparable period in 2007. In addition to the items noted above, interest expense increased $499,537. This increase during the current quarter was due to the $319,135 of interest expense we incurred in the current quarter on a debt conversion. We also incurred additional interest costs associated with our notes payable and related amortization of associated debt discounts as a result of our $6.3 million financing and the exchange of our short-term notes for 5 year convertible notes during the third and fourth quarters of fiscal 2008. Additionally, other income increased $40,440 in the quarter ended July 31, 2008 compared to the same period ended January 31, 2007 due to additional interest that we earned on our cash and cash equivalents.

Fiscal year 2008 compared to fiscal year 2007

For the fiscal year ended April 30, 2008, other income decreased to $105,629 from $120,027 in the fiscal year ended April 30, 2007. Other income consists principally of rental income. The decrease during 2008 is attributed to a one-time gain from the settlement of a vendor payable in fiscal 2007.

Research and development expenses increased from $752,614 for the fiscal year ended April 30, 2007, to $939,998 for the fiscal year ended April 30, 2008. Because of the nature of our ongoing research and development activities, accounting periods may reflect significant changes in expenses resulting from the timing of research related to our three developmental products. We decreased expenditures relating to Oxycyte™ Phase II clinical trials during fiscal 2007 and into fiscal 2008 due to a shortage of working capital. Due to the $6.3 million financing we obtained during the third and fourth quarters of fiscal 2008, we were able to resume funding of our Phase II clinical trials and increase our lab personnel and related expenses.

General and administrative expenses of $1,992,687 for fiscal year 2008 increased 95 percent or $972,892 over fiscal year 2007 expenses of $1,019,795. This change is primarily due to a $716,000 increase in our noncash compensation relating to the issue of compensatory stock options and warrants, an increase in our payroll expenses of $144,000, and an increase in our accounting expenses of $71,000 over the amounts incurred in fiscal 2007.

Interest charges associated with the convertible notes and short-term notes, including amortization of the original issue discount, debt issue costs, common stock purchase warrant value and beneficial conversion features, aggregated to $3,611,902 for fiscal 2008 as compared to $1,678,488 for fiscal 2007. This increase is a result the significant additional financing costs related to our $6.3 million financing and the exchange of our short-term notes for five-year convertible notes during the third and fourth quarters of fiscal 2008. During the year ended April 30, 2008, we also incurred a debt extinguishment loss of $250,097 related to the exchange of our short-term notes for five-year convertible notes. The debt extinguishment was recognized in accordance with EITF 96-19 and results principally from the write off of unamortized debt discounts and debt issue costs. We also incurred a $32,113 impairment loss on our lab equipment during fiscal 2008.

For the year ended April 30, 2008, we incurred a loss of $6,721,168 compared to a loss of $3,330,870 for the previous fiscal year.

Liquidity, capital resources and plan of operation

We have financed our operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. As of July 31, 2008, we had $6,140,495 of total current assets and working capital of $5,562,571. Our practice is to invest excess cash, where available, in short-term money market investment instruments.

During the third quarter of fiscal year 2008, the Company exchanged its outstanding short term loans for five-year convertible notes with a face amount of $6,204,767. The notes are unsecured, convertible into shares of common stock at $0.247 per share, and were issued with a 55% original issue discount totaling $3,412,622. In addition, the Company issued five-year warrants to purchase 12,560,257 shares of common stock at $0.247 per share to investors. Additional discounts of $1,739,499 and $1,052,646 were recorded for the relative fair values of the warrants and beneficial conversion feature, respectively. Pursuant to this exchange transaction, the Company recorded a debt extinguishment loss of $250,097.

During the third and fourth quarters of fiscal year 2008, the Company received a total of $6,335,000 in cash from the sale of convertible notes, with a total face amount of $14,077,778. The notes are convertible at any time prior to maturity into a total

of 56,995,053 shares of common stock, or $0.247 per share. In connection with the issuance of these obligations, the Company recorded a 55% original issue discount of $7,742,778, and additional discounts of $4,864,998 related to the relative fair value of the 28,497,501 five-year warrants to purchase common stock at $0.247 per share that were issued in the transaction, and $1,470,002 for the relative fair value of the embedded beneficial conversion feature. The Company also incurred total costs of $5,510,562 for capital raising services on these transactions. The costs of the capital raising services include a $369,215 cash fee, plus $768,337 for the fair value of 2,088,272 restricted shares of common stock, plus $4,373,010 for the fair value of warrants to purchase 21,853,086 common shares at prices ranging from $0.20 to $0.28.

During the quarter ended July 31, 2008, net cash provided by financing activities was $2,115,061, which included $2,147,714 proceeds from the exercise of warrants, less $32,653 in repayments on a short term note. Of the $2,147,714 proceeds received from warrant exercises, we have an obligation to return $140,000 due to a pricing error in the exercise. This obligation is included in our current liabilities at July 31, 2008. Net cash of $874,169 was used to fund operating activities and $33,699 was used for investing activities, which included $14,079 in lab equipment expenditures, $16,228 for the purchase of licensing rights on three patents, and $3,392 of other capitalized patents costs. Consequently, our cash and cash equivalents increased from $1,207,193 at April 30, 2008 to $6,087,826 at July 31, 2008. We do not have any lines of credit or other borrowing arrangements with lenders.

We are in the pre-clinical and clinical trial stages in the development of our products. Under an Investigational New Drug application filed with the FDA, we completed Phase I clinical studies on Oxycyte in December 2003. The results of the Phase I study were in line with our expectations for the performance of Oxycyte. We submitted a report to the FDA along with a Phase II protocol, received FDA approval, and started Phase II testing in the fourth quarter of 2004, which is expected to continue through 2009 for Phase II-b studies in severe traumatic brain injury. Even if we are successful with our Phase II study, we must then conduct a Phase III clinical study and, if that is successful, file with the FDA and obtain approval of a Biologics License Application to begin commercial distribution, all of which will take more time and funding to complete. Our other products, Fluorovent and the glucose biosensor, must undergo further development and testing prior to submission to the FDA for approval to initiate clinical trials, which also requires additional funding. Management is actively pursuing private and institutional financing, as well as strategic alliances and/or joint venture agreements to obtain the necessary additional financing and reduce the cost burden related to the development and commercialization of our products. We expect our primary focus will be on funding the continued testing of Oxycyte, since this product is the furthest along in the regulatory review process. Our ability to continue to pursue testing and development of our products beyond 2009 depends on achieving license income, or obtaining outside financial resources. There is no assurance that needed license agreement, or financing will occur or that we will succeed in obtaining the necessary resources.

We are entirely dependent on outside financing to continue our operations. We will not generate operating revenue unless and until one of our products is approved for commercial sale and sales activity begins. We will require substantial additional funds to complete clinical trials, pursue regulatory approval for our products, establish commercial scale manufacturing capabilities, and establish marketing, sales, and administrative capabilities. Expenditures for these purposes will result in substantial losses for at least the next several years. The expense and the time required to realize any product revenues or profitability are highly uncertain. We cannot ensure that we will be able to achieve product revenues or profitability on a sustained basis, or at all. The foregoing factors highlight that the Company must achieve license agreements, or additional financing by end of 2009.

We do have the working capital necessary to fund our operations in fiscal year 2009. By end of 2009, we will need additional financing to cover administrative expenses and on-going expenses of testing Oxycyte. Management is actively seeking additional sources of equity and/or debt financing; however there is no assurance that any additional funding will be available in time. Should we be unable to obtain additional financing to meet mid-term needs, we may be forced to cease operations. Our ability to continue as a going concern depends on success of these activities.

Critical accounting policies

Our discussion and analysis of our financial condition and results of operations is based upon the financial statements presented in this report, 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 disclosure of contingent liabilities. On an on-going basis, we evaluate our estimates, including those related to stock-based compensation and contingencies. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form 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.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our financial statements:

Stock-Based Compensation—We account for stock-based compensation as prescribed by of SFAS No. 123R, which requires stock options and warrants issued to employees and nonemployees to be valued using the fair value method. Under the fair value based method, compensation cost is recorded based on the value of the award at the grant date and is recognized over the service period.

The fair value of each option and warrant grant was estimated at the grant date using the Black-Scholes option-pricing model. The Black–Scholes option valuation model was developed for use in estimating the fair value of traded options and warrants that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility and expected term.

Convertible Notes—If the conversion feature of conventional convertible debt provides for a rate of conversion that is below market value, this feature is characterized as a beneficial conversion feature (“BCF”). A BCF is recorded by the Company as a debt discount pursuant to EITF Issue No. 98-5 (“EITF 98-05”), Accounting for Convertible Securities with Beneficial Conversion Features or Contingency Adjustable Conversion Ratio, and EITF Issue No. 00-27, Application of EITF Issue No. 98-5 to Certain Convertible Instruments. In those circumstances, the convertible debt will be recorded net of the discount related to the BCF. The Company amortizes the discount to interest expense over the life of the debt using the effective interest method.

Registration Payment Arrangements—In connection with prior private placements of our common stock and warrants to purchase shares of our common stock, we entered into agreements that committed us to timely register the shares of common stock purchased as well as the shares underlying the issued warrants. Those registration agreements specified potential cash penalties if we did not timely register the related shares with the SEC.

In accordance with EITF 00-19, “Accounting for Derivative Financial Instruments Indexed To, and Potentially Settled In a Company’s Own Stock,” when the potential cash penalties were included in registration payment arrangements, the estimated fair value of the warrants would be recorded as a liability, with an offsetting reduction to additional paid-in capital received from the private placement. The fair value of the warrants would be estimated using the Black-Scholes option pricing model.

Under EITF 00-19, the estimated fair value of the warrants would be re-measured at each reporting date and on the date of effectiveness of the related registration statement, with the increase in fair value recorded as other expense in our Statement of Operations. As of the date of effectiveness of the registration statement, the warrant liability would be reclassified to additional paid-in capital, evidencing the non-impact of these adjustments on our financial position and business operations.

In December 2006, the FASB issued FASB Staff Position, or FSP, EITF No. 00-19-2, “Accounting for Registration Payment Arrangements.” This FSP specifies that companies that enter into agreements to register securities will be required to recognize a liability if a payment to investors for failing to fulfill the agreement is probable and can be reasonably estimated. This accounting differs from the guidance in EITF 00-19, which required a liability to be recognized and measured at fair value, regardless of probability.

EITF 00-19-2 is effective immediately for registration payment arrangements and the financial instruments subject to those arrangements that we enter into or modify after the date of issuance of this FSP. For our registration payment arrangements and financial instruments subject to those arrangements that were entered prior to the issuance of this FSP, the guidance was effective beginning January 1, 2007.

Long-Lived Assets—Our intangible assets consist of patents related to our various technologies. These assets are amortized on a straight-line method over their estimated useful life, which ranges from eight to ten years. We review these intangible assets for impairment in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (“SFAS 144”).

Recent Accounting Pronouncements—

SFAS 157—In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”), which defines fair value, establishes a framework for measuring fair value in GAAP, and expands disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements, but provides guidance on how to measure fair

value by providing a fair value hierarchy used to classify the source of the information. SFAS 157 was originally effective for fiscal years beginning after November 15, 2007, but was partially delayed by one year for non-financial assets and liabilities as detailed within FASB Staff Position 157-2. Oxygen Biotherapeutics is currently evaluating SFAS 157 and FASB Staff Position 157-2, and does not believe these pronouncements will materially affect its financial position or results of operations.

SFAS 159—In February 2007, the FASB issued SFAS 159,The Fair Value Option for Financial Assets and Financial Liabilities Including an Amendment of FASB Statement No. 115(“SFAS 159”), which permits entities to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is effective as of the beginning of fiscal years after November 15, 2007. Oxygen Biotherapeutics adopted SFAS 159 on May 1, 2008, and does not believe it will materially affect its financial position or results of operations.

SFAS No. 141(R)—In December 2007, the FASB issued Statement No. 141(R),Business Combinations. This Statement replaces FASB Statement No. 141,Business Combinations. This Statement retains the fundamental requirements in Statement 141 that the acquisition method of accounting (which Statement 141 called thepurchase method) be used for all business combinations and for an acquirer to be identified for each business combination. This Statement defines the acquirer as the entity that obtains control of one or more businesses in the business combination and establishes the acquisition date as the date that the acquirer achieves control. Statement 141 did not define the acquirer, although it included guidance on identifying the acquirer, as does this Statement. This Statement’s scope is broader than that of Statement 141, which applied only to business combinations in which control was obtained by transferring consideration. By applying the same method of accounting—the acquisition method—to all transactions and other events in which one entity obtains control over one or more other businesses, this Statement improves the comparability of the information about business combinations provided in financial reports. This Statement applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. An entity may not apply it before that date. Oxygen Biotherapeutics is currently evaluating SFAS 141(R), and has not yet determined its potential impact on its future results of operations or financial position.

SFAS No. 160—In December 2007, the FASB issued Statement No. 160,Noncontrolling Interests in Consolidated Financial Statements—an Amendment of ARB No. 51. This Statement amends ARB 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. Before this Statement was issued, limited guidance existed for reporting noncontrolling interests. As a result, considerable diversity in practice existed. So-called minority interests were reported in the consolidated statement of financial position as liabilities or in the mezzanine section between liabilities and equity. This Statement improves comparability by eliminating that diversity. This Statement is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. Earlier adoption is prohibited. The effective date of this Statement is the same as that of the related Statement 141(R). This Statement shall be applied prospectively as of the beginning of the fiscal year in which this Statement is initially applied, except for the presentation and disclosure requirements. The presentation and disclosure requirements shall be applied retrospectively for all periods presented. Oxygen Biotherapeutics is currently evaluating SFAS 160 and has not yet determined its potential impact on its future results of operations or financial position.

SFAS No. 161—In March 2008, the FASB issued SFAS No. 161,“Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133.” SFAS No. 161 requires enhanced disclosures about an entity’s derivative and hedging activities. These enhanced disclosures will discuss (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for under Statement 133 and its related interpretations, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Oxygen Biotherapeutics has not determined the impact, if any SFAS No. 161 will have on its financial statements.

Johnson held the position of Chief Financial Officer until his resignation August 17, 2007, which was immediately following the filing of Oxygen Biotherapeutics’ annual report on Form 10-K for the year ended April 30, 2007. Accordingly, Mr. Johnson did not perform services or functions normally associated with the office of chief financial officer for the financial reporting periods in fiscal year 2008 and Oxygen Biotherapeutics did not accrue or pay to Mr. Johnson any compensation in relation to fiscal year 2008. For his services as Chief Financial Officer in fiscal years 2007 and 2006, his compensation was $40,000 in each year.

Option grants

Oxygen Biotherapeutics adopted a stock option plan in October 1999, which was ratified by a vote of the shareholders during fiscal year ended April 30, 2001. The 1999 plan provides for the granting of incentive and non-qualified options to officers, directors, consultants and key employees to purchase up to 4,000,000 shares of Oxygen Biotherapeutics’s common stock at prices not less than the fair market value of the stock at the date of grant for incentive options. The option expiration dates are determined at the date of grant, but may not exceed ten years. The total number of options issued under the Plan at April 30, 2008 were 3,345,000 with a weighted average exercise price of $0.23.

In addition, Oxygen Biotherapeutics has issued options outside the Plan. At April 30, 2008 the total non-qualified options outstanding were 4,490,000 with a weighted average exercise price of $0.21.

Employment Contracts

Effective March 25, 2008, Chris J. Stern, our Chairman of the Board, was appointed to the office of Chief Executive Officer and is continuing in the position of Chairman. At the time Mr. Stern was elected to the Board in November 2007 and appointed Chairman, we agreed to pay to Mr. Stern’s consulting firm a monthly fee of $15,000 for consulting services Mr. Stern provides to us.

Furthermore, we agreed (i) to issue to Mr. Stern, as of the date of his election to the Board, options to purchase 1,000,000 common shares at an exercise price of $0.245 per share that expire three years from the date of grant, and (ii) if, in the two years following the date of the agreement, Oxygen Biotherapeutics enters into a license agreement or is sold, to issue to Mr. Stern at the closing of the transaction options to purchase an additional 4,000,000 common shares at an exercise price of $0.245 per share that expire three years from the date of grant. In September 2008, we entered into a license agreement pertaining to our biosensor implant product, and we issued the option on 4,000,000 shares to Mr. Stern. As a result of Mr. Stern’s appointment as Chief Executive Officer, the Board has agreed to pay Mr. Stern’s consulting company an additional $5,000 per month by way of consulting fees and also to pay the consulting company $2,500 per month for additional secretarial and administration expenses. Furthermore, the Board has also agreed (i) to issue to Mr. Stern an aggregate of 14,000 shares of Oxygen Biotherapeutics’ common stock on the 1st of every month, commencing with April 1, 2008, for so long as Mr. Stern serves on the Board, and (ii) to issue and pay to Mr. Stern, upon his termination as a board member for whatever reason, with or without cause, an aggregate of 100,000 shares of Oxygen Biotherapeutics’ common stock and the sum of $200,000, payable upon such termination.

Richard Kiral served as Vice President of Product Development through much of fiscal year 2008 for which he was compensated at the rate of $167,000 per year and was paid additional compensation in the form of an automobile allowance, medical and dental coverage, participation in the Executive Bonus Plan, $200,000 life insurance paid for by the corporation and payable to a beneficiary named by the insured, and the grant of an option for 75,000 shares annually. Effective March 25, 2008, the Board appointed Dr. Kiral to serve as President and Chief Operating Officer of Oxygen Biotherapeutics. Pursuant to an agreement executed on March 26, 2008, Dr. Kiral’s employment agreement with Oxygen Biotherapeutics was amended to provide for an increase in annual salary to $239,000, payment of a sum equal to annual base salary and performance bonus upon termination without cause (as defined in the agreement), issuance on the first day of each month commencing April 1, 2008, of options to purchase 20,000 common shares with an exercise price based on market value, for so long as Dr. Kiral serves on the Board, and payment of 100,000 common shares and the sum of $200,000 upon Dr. Kiral’s termination by Oxygen Biotherapeutics as a board member, with or without cause.

We have agreed to pay Charles H. Seeman an annual salary of $100,000, as well as an $800 per month car allowance, participation in our employee benefit plans, and other customary benefits. We will also pay Mr. Seeman a $10,000 cash bonus within fifteen days following the filing of our first periodic report under the Securities Exchange Act of 1934 that reports our disclosure controls and procedures are effective, provided such periodic report is filed before September 22, 2009. We will pay an additional bonus of $10,000 on or before October 7, 2009, if all required reports under the Securities Exchange Act of 1934 are filed during the one-year period ending September 22, 2009 within applicable deadlines, subject to Mr. Seeman’s continues employment on September 22, 2009. Mr. Seeman will be granted an option effective December 23, 2008 (subject to his continued employment) under our 1999 Amended Stock Plan to purchase 50,000 common shares that will vest, subject to continued employment, on September 23, 2009, and be exercisable for a term of three years from vesting at an exercise price of $0.46 per share, which was market price on the date of employment. Subject to his continued employment we will grant options under the 1999 Amended Stock Plan to Mr. Seeman annually in September to purchase 50,000 common shares that will vest, subject to continued employment, one year following the date of grant and be exercisable for a term of three years from vesting at an exercise price equal to the market price for the common stock on the trading day prior to the date of grant.

On November 19, 2007, Robert Nicora, the former President and Chief Executive Officer resigned his positions. We entered into a severance agreement that provides for a one year severance payroll and benefits package consisting of $198,450 in gross salary, a medical plan benefit of $21,244, a car benefit of $3,850, a life insurance benefit of $4,765, and a retirement benefit of $5,198. We also paid Mr. Robert Nicora unpaid salaries of $99,225 and repaid a $39,500 loan plus $6,001 for income taxes. The payment schedule was $125,000 December 31, 2007, and three equal payments of $84,411 on February 15, 2008, May 15, 2008, and August 15, 2008, and has been paid in full. Oxygen Biotherapeutics also extended the term of any employee stock options that expire within three years of the effective date of the resignation.

Robert J. Larsen became interim President and Chief Executive Officer on November 20, 2007, and died unexpectedly on March 24, 2008. At the time he became an officer we agreed to pay to Mr. Larsen for his services at the rate of $120,000 per year and a car allowance of $550 per month, and issue to him for each month of service options to purchase 30,000 shares of our common stock exercisable for a term of three years following issuance with an exercise price equal to the market price on the date of each monthly issuance. In addition, we agreed to pay for Mr. Larsen’s housing cost in California during his service as an officer. Further,

an option that Mr. Larsen held to purchase 300,000 shares of our common stock at an exercise price of $0.13 per that was scheduled to expire in February 2008 was extended to November 19, 2010. On March 25, 2008, the Board of Directors approved the issuance of options to the Estate of Robert J. Larsen to purchase 300,000 shares of common stock at an exercise price of $0.30 per share.

The assumptions we used in valuing these awards are described in Note G to our Consolidated Financial Statements included in this Form 10-K.

Until November 19, 2007 each outside board member received compensation of $12,000 per year and options to purchase 10,000 shares of common stock exercisable over a term of ten years at an exercise price based on the closing market price of our common stock on the date of issuance. We also reimburses Directors for customary expenses related to attending board, committee and stockholder meetings.

The Certificate of Incorporation and Bylaws are incorporated by reference as exhibits to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

an exchange distribution in accordance with the rules of the applicable exchange;

privately negotiated transactions;

broker-dealers may agree with the selling security holders to sell a specified numberCertificate of such shares at a stipulated price per share;

a combination of any such methods of sale;Incorporation and

any other method permitted pursuant to applicable law.

The selling security holders may also sell shares under Rule 144 adopted under the Securities Act of 1933, if available, rather than under this prospectus.

Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent Bylaws for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling security holders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved, but in any event the maximum commission or discount that may be paid or received by any broker-dealer for sale or placement of the common stock for the selling security holders cannot exceed eight percent.

The selling security holders may from time to time pledge or grant a security interest in some or all of the shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell shares of common stock from time to time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling security holders under this prospectus.

Upon Oxygen Biotherapeutics being notified in writing by a selling security holder that any material arrangement has been entered into with a broker-dealer for the sale of common stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act of 1933, disclosing (i) the name of each such selling security holder and of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such the shares of common stock were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction. In addition, upon Oxygen Biotherapeutics being notified in writing by a selling security holder that a donee or pledgee intends to sell more than 500 shares of common stock, a supplement to this prospectus will be filed if then required in accordance with applicable securities law.

The selling security holders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling security holders and any broker-dealers or agentsprovisions that are involved in selling the shares may be deemedimportant to be “underwriters” within the meaningyou.

Our authorized capital stock consists of the Securities Act of 1933 in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act of 1933. Discounts, concessions, commissions and similar selling expenses, if any, that can be attributed to the sale of securities will be paid by the selling security holder and/or the purchasers. We are not aware of any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of shares of common stock covered by this prospectus that have been entered into by any of the selling security holders, nor are we aware of any underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling security holders.

Oxygen Biotherapeutics has advised each selling security holder that it may not use shares registered on the registration statement of which this prospectus is a part to cover short sales of common stock made prior to the date on which the registration statement shall have been declared effective by the Securities and Exchange Commission. If a selling security holder uses this prospectus for any sale of the common stock, it will be subject to the prospectus delivery requirements of the Securities Act of 1933. The selling security holders will be responsible to comply with the applicable provisions of the Securities Act of 1933 and Securities Exchange Act of 1934, and the rules and regulations adopted thereunder, including, without limitation, Regulation M, as applicable to such selling security holders in connection with resales of their respective shares under this prospectus.

Oxygen Biotherapeutics is required to pay all fees and expenses incident to the registration of the shares, but it will not receive any proceeds from the sale of the common stock. Oxygen Biotherapeutics has agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act of 1933.

Common stock

stock.

Holders of the common stock are entitled to one vote per share on all matters submitted to the stockholders for a vote. There are no cumulative voting rights in the election of directors. The shares of common stock are entitled to receive such dividends as may be declared and paid by the boardBoard of directorsDirectors out of funds legally available there fortherefor and to share, ratably, in the net assets, if any, of Oxygen Biotherapeutics upon liquidation. The stockholders have no preemptive rights to purchase any shares of our capital stock.

Preferred stock

The board of directors, without further action by the holders of the common stock, is authorized to classify any shares of our authorized but unissued preferred stock in one or more series. With respect to each series, the board of directors may determine:

The number of shares which shall constitute such series;

The rate of dividend, if any, payable on shares of such series;

Whether the shares of such series shall be cumulative, non-cumulative or partially cumulative as to dividends, and the dates from which any cumulative dividends are to accumulate;

Whether the shares of such series may be redeemed, and, if so, the price or prices at which and the terms and conditions on which shares of such series may be redeemed;

The amount payable upon shares of such series in the event of the voluntary or involuntary dissolution, liquidation or winding up of the affairs of Oxygen Biotherapeutics;

The voting rights, if any, of the shares of such series;

The terms and conditions, if any, on which shares of such series may be converted into shares of capital stock of Oxygen Biotherapeutics of any other class or series;

Whether the shares of such series are to be preferred over shares of capital stock of Oxygen Biotherapeutics of any other class or series as to dividends, or upon the voluntary or involuntary dissolution, liquidation, or winding up of the affairs of Oxygen Biotherapeutics, or otherwise; and

Any other characteristics, preferences, limitations, rights, privileges, immunities or terms not inconsistent with the provisions of the Charter.

The availability of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of discouraging takeover proposals, and the issuance of preferred stock could have the effect of delaying or preventing a change in control of Oxygen Biotherapeutics not approved by the board of directors.

Limitation on directors’ liabilities

Pursuant to the certificate of incorporation and under Delaware law, directors and executive officers are not liable to Oxygen Biotherapeutics or its stockholders for monetary damages for breach of fiduciary duty, except liability in connection with a breach of duty of loyalty, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, dividend payments or stock repurchases illegal under Delaware law, or any transaction in which a director has derived an improper personal benefit.

Our certificate of incorporation and bylaws provide that we will indemnify our directors and officers to the fullest extent permitted by law against liabilities and expenses incurred in connection with litigation in which these persons may be involved because of their offices with us if they acted in good faith or in a manner reasonably believed to be in or not opposed to our best interests. However, nothing in the certificate of incorporation and bylaws protects or indemnifies a director, officer, employee, or agent against any liability to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office. To the extent that a director or officer has been successful in defense of any proceeding, our bylaws provide that he shall be indemnified against reasonable expenses incurred in connection therewith.

Penny stock rules

It is likely public transactions in our stock will be covered by the Penny Stock rules, which impose significant restrictions on broker-dealers and may affect the resale of our stock. A penny stock is generally a stock that

Is not listed on a national securities exchange or Nasdaq,

Is listed in “pink sheets” or on the NASD OTC Bulletin Board,

Has a price per share of less than $5.00 and

Is issued by a company with net tangible assets less than $5 million.

The penny stock trading rules impose additional duties and responsibilities upon broker-dealers and salespersons effecting purchase and sale transactions in common stock and other equity securities, including

Determination of the purchaser’s investment suitability,

Delivery of certain information and disclosures to the purchaser, and

Receipt of a specific purchase agreement from the purchaser prior to effecting the purchase transaction.

Many broker-dealers will not effect transactions in penny stocks, except on an unsolicited basis, in order to avoid compliance with the penny stock trading rules. It is likely our common stock will be covered by the penny stock trading rules. Therefore, such rules may materially limit or restrict a holder’s ability to resell our common stock, and the liquidity typically associated with other publicly traded equity securities may not exist.

Transfer agent

The transfer agent for the common stock is Interwest Transfer Company, Salt Lake City, Utah.

Our common stock is traded on the Nasdaq Capital Market and is quoted under the symbol OXBT.

Series A Convertible Preferred Stock
General
There are currently no shares of Series A Convertible Preferred Stock outstanding, and we do not currently expect to issue any in the future. Under our Certificate of Incorporation, as amended, our Board of Directors is authorized, without further stockholder action, to provide for the issuance of up to 10,000,000 shares of preferred stock, par value $0.0001 per share, in one or more series, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations and restrictions thereof. By the filing of a Certificate of Designations with the Secretary of State of the State of Delaware, we designated 7,500 shares of our authorized but unissued preferred stock as a series of our preferred stock, designated as Series A Convertible Preferred Stock, of which 6,000 shares have been issued.
Holders of the Series A Convertible Preferred Stock have no preemptive or preferential right to purchase or subscribe to stock, obligations, warrants or other of our securities of any class, other than the right to convert into shares of our common stock as described herein and if we grant, issue or sell options, convertible securities or rights to purchase stock, warrants, securities or other property to the holders of common stock, then holders of Series A Convertible Preferred Stock would have the right to acquire such rights which such holder could have acquired if such holder had held the number of shares of common stock acquirable upon conversion of the Series A Convertible Preferred Stock held immediately before the record date for such grant, issuance or sale. We do not intend to list the Series A Convertible Preferred Stock on any securities exchange.
Ranking
The Series A Convertible Preferred Stock, with respect to dividend rights or rights upon our liquidation, winding-up or dissolution, ranks:
●  senior to our common stock, and, except as described below, to each other class of capital stock established after the original issue date of the Series A Convertible Preferred Stock (which we will refer to as the “Issue Date”), (which we will refer to collectively as “Junior Stock”);
●  equally with any class of capital stock established after the Issue Date, issued after the express written consent of the holders of a majority of the aggregate outstanding shares of Series A Convertible Preferred Stock, the terms of which expressly provide that the right of the holders thereof, either as to the payment of dividends or as to distributions in the event of our voluntary or involuntary liquidation, dissolution or winding up, (i) are not given preference over the rights of the holders of the Series A Convertible Preferred Stock and (ii) rank on an equality with the rights of the holders of the Series A Convertible Preferred Stock (which we will refer to collectively as “Parity Stock”); and
12

●  junior to each class of capital stock established after the Issue Date, issued after the express written consent of the holders of a majority of the aggregate outstanding shares of Series A Convertible Preferred Stock, the terms of which expressly provide that the rights of the holders thereof either as to the payment of dividends or as to distributions in the event of our voluntary or involuntary liquidation, dissolution or winding up are given preference over the right of the holders of the Series A Convertible Preferred Stock (which we will refer to collectively as “Senior Stock”).
Dividends
Holders of the Series A Convertible Preferred Stock are entitled to receive dividends at the rate of 7% per annum, paid monthly in arrears. Dividends will be calculated without giving effect to any reduction for payment of installments. We may elect to pay dividends in cash or, subject to certain conditions, in shares of our common stock.
If we pay dividends in shares of common stock, the shares of common stock will be valued for such purposes, at the average of the volume weighted average prices (“VWAP”) for the five trading days in which the VWAP is at its lowest price during the twenty (20) consecutive trading days, excluding the two trading days during such period in which the VWAP is at its lowest price, ending immediately prior to the twenty-third (23rd) trading day prior to the applicable dividend payment date, subject to a “true up” based on the five trading days in which the VWAP is at its lowest price during the twenty (20) consecutive trading days ending on the trading day immediately prior to the applicable dividend or amortization payment date.
Series A Convertible Preferred Stock is entitled to participate on an as-converted basis in any distributions or dividends paid to the common stock.
Liquidation Preference
In the event of our voluntary or involuntary liquidation, dissolution or winding-up, each holder of Series A Convertible Preferred Stock will be entitled to receive and to be paid out of our assets available for distribution to our stockholders, before any payment or distribution is made to holders of Junior Stock (including our common stock), a liquidation preference equal to the initial stated value of such holder’s Series A Convertible Preferred Stock, plus accrued and unpaid dividends and a make-whole amount equal to dividends that would have accrued on the Series A Convertible Preferred Stock had such shares remained outstanding through January 12, 2013. If, upon our voluntary or involuntary liquidation, dissolution or winding-up, our assets available for distribution to our stockholders shall be insufficient to pay the holders of shares of Series A Convertible Preferred Stock the full amount to which they shall be entitled, the holders of the Series A Convertible Preferred Stock and the Parity Stock will share equally and ratably in any distribution of our assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. After payment of the full amount of the liquidation preference and accrued and unpaid dividends to which they are entitled, the holders of the Series A Convertible Preferred Stock will be entitled to participate with the holders of our common stock on an as-converted to common stock basis in the distribution of our remaining assets.
Voting Rights
The holders of the Series A Convertible Preferred Stock will generally have no voting rights, except as required from time to time by law and except that the consent of the holders of a majority of the outstanding Series A Convertible Preferred Stock will be required to (i) alter or amend the Certificate of Designations or any other organizational document of the Company in a manner that adversely affects the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series A Convertible Preferred Stock, (ii) increase or decrease the number of authorized shares of Series A Convertible Preferred Stock, (iii) create or authorize any new class or series of shares that has a preference over or is on a parity with the Series A Convertible Preferred Stock with respect to dividends or the distribution of assets on the liquidation, dissolution or winding up of the Company; (iv) purchase, repurchase or redeem any shares of common stock (other than (a) pursuant to equity incentive agreements with employees giving us the right to repurchase shares upon the termination of services at cost and (b) upon surrender of restricted stock in connection with tax withholding); (v) pay dividends or make any other distribution on the common stock or other Capital Stock (other than the Series A Convertible Preferred Stock); (vi) increase the amount of any securities issuable pursuant to any employee benefit plan, agreement or arrangement which has been approved by our Board of Directors; (vii) whether or not prohibited by the terms of the Series A Convertible Preferred Stock, circumvent a right of the Series A Convertible Preferred Stock; (viii) amend any provision of the Certificate of Designations with respect to the Preferred Shares; or (ix) generally incur debt, other than equipment leases and vendor debt. In matters where holders of the Series A Convertible Preferred Stock are entitled to vote, each share of the Series A Convertible Preferred Stock shall be entitled to one vote.

13

Conversion Rights
Holders of Series A Convertible Preferred Stock may elect to convert shares of Series A Convertible Preferred Stock into shares of our common stock at the then-existing conversion price at any time. The conversion rate is determined by dividing the conversion amount (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A Convertible Preferred Stock) by the conversion price in effect at the time of conversion. The initial conversion price will be subject to adjustment upon the issuance of any common stock or securities convertible into common stock below the then-existing conversion price. All shares of common stock distributed upon conversion will be freely transferable without restriction under the Securities Act of 1933, as amended (other than by our affiliates). If a holder of shares of Series A Convertible Preferred Stock elects to convert its shares into common stock, the holder shall also be entitled to receive the make-whole amount, which, the Company may pay in shares of common stock, subject to certain conditions.
Company Conversion/Redemption
On each one month anniversary of the Issue Date of the Series A Convertible Preferred Stock we will redeem one-sixth of the shares of Series A Convertible Preferred Stock held by a holder of Series A Convertible Preferred Stock. We may pay these monthly amortization payments in cash or, subject to certain conditions, in shares of our common stock.
If we pay the amortization payment in shares of common stock, we will deliver that number of shares of common stock equal to the amount of the monthly amortization payment divided by a per share amortization price, which shall be the lesser of (i) the then-existing conversion price and (ii) 90% of a calculated market price per share of common stock. The market price per share is calculated as described in “Description of Convertible Preferred Stock – Dividends” above.
Under certain circumstances, including our breach of the terms contained in the Certificate of Designations, the holders of Series A Convertible Preferred Stock may require us to redeem the outstanding balance of the Series A Convertible Preferred Stock in cash at the higher of 125% of the applicable conversion price or the current market price, plus, in either case, the make-whole amount. In addition, upon a change-in-control, the holders of Series A Convertible Preferred Stock may require us to redeem the outstanding shares of Series A Convertible Preferred Stock in cash at a premium as described in the Certificate of Designations.
Limitations on Issuance of Common Stock
Holders of Series A Convertible Preferred Stock may not convert their shares of Series A Convertible Preferred Stock to the extent that the conversion would result in the holder and its affiliates beneficially owning 4.99% or more (subject to adjustments as set forth in the Certificate of Designations) of our common stock. The amount of beneficial ownership of the holder and its affiliates will be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations of that section.
Certain Nasdaq continued listing standards limit the number of securities that may be issued in a particular offering, when the issuance or potential issuance would result in a “change of control” as defined by Nasdaq. Accordingly, without prior stockholder approval, common stock may not be issued upon the conversion or redemption of, or as a dividend on, the Series A Convertible Preferred Stock, as applicable, if such conversion, redemption or dividend would result in aggregate issuances by us of common stock equal to or greater than 20% of the outstanding shares of our common stock immediately prior to the offering.
Series B-1 Convertible Preferred Stock
General
There are currently 540 shares of Series B-1 Convertible Preferred Stock outstanding, and we do not currently expect to issue any additional shares of Series B-1 Convertible Preferred Stock in the future. Under our Certificate of Incorporation, as amended, our Board of Directors is authorized, without further stockholder action, to provide for the issuance of up to 10,000,000 shares of preferred stock, par value $0.0001 per share, in one or more series, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations and restrictions thereof. By the filing of a Certificate of Designations with the Secretary of State of the State of Delaware, we designated 1,600 shares of our authorized but unissued preferred stock as a series of our preferred stock, designated as Series B-1 Convertible Preferred Stock, of which 1,600 shares have been issued.
14

Liquidation Preference
The Series B-1 Convertible Preferred Stock ranks, with respect to rights upon liquidation, winding-up or dissolution, (1) senior to common stock, (2) senior to any series of preferred stock ranked junior to the Series B-1 Convertible Preferred Stock, and (3) junior to all existing and future indebtedness of the Company.
Voting Rights
Except as required by law, holders of the Series B-1 Convertible Preferred Stock do not have rights to vote on any matters, questions or proceedings, including the election of directors. However, as long as any shares of Series B-1 Convertible Preferred Stock are outstanding, we will not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series B-1 Convertible Preferred Stock, (1) alter or change adversely the powers, preferences or rights given to the Series B-1 Convertible Preferred Stock or alter or amend the certificate of designation, (2) authorize or create any class of stock ranking as to dividends, redemption or distribution of assets upon liquidation senior to, or otherwise pari passu with, the Series B-1 Convertible Preferred Stock, (3) amend our certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series B-1 Convertible Preferred Stock, (4) increase the number of authorized shares of Series B-1 Convertible Preferred Stock, or (5) enter into any agreement with respect to any of the foregoing.
Delaware Law
Notwithstanding certain protections in the certificate of designation for holders of Series B-1 Convertible Preferred Stock, Delaware law also provides holders of preferred stock with certain rights. The holders of the outstanding shares of Series B-1 Convertible Preferred Stock will be entitled to vote as a class upon a proposed amendment to the certificate of incorporation if the amendment would:
●  increase or decrease the aggregate number of authorized shares of Series B-1 Convertible Preferred Stock;
●  increase or decrease the par value of the shares of Series B-1 Convertible Preferred Stock; or
●  alter or change the powers, preferences, or special rights of the shares of Series B-1 Convertible Preferred Stock so as to affect them adversely.
Conversion
Subject to certain ownership limitations as described below, the Series B-1 Convertible Preferred Stock is convertible at any time at the option of the holder into shares of our common stock at a conversion ratio determined by dividing the stated value of the Series B-1 Convertible Preferred Stock (or $1,000) by a conversation price of $0.25 per share. The conversion price is subject to adjustment in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. In addition, until such time that, for at least 20 consecutive trading days, the volume weighted average price of our common stock exceed $1.00 (as adjusted for reverse and forward stock splits and similar transactions) and the daily dollar trading volume during such period exceeds $100,000 per trading day, if we sell or grant any option to purchase or sell any common stock or common stock equivalents entitling any person to acquire shares of common stock at an effective price per share that is lower than the conversion price then in effect (such lower price, the “Base Conversion Price”), then the conversion price shall be reduced to equal the Base Conversion Price.
On the 10th trading day following the earlier of (a) the first reverse split of our common stock while the Series B-1 Convertible Preferred Stock is outstanding or (b) the 75th calendar day following the closing of the initial sale of the Series B-1 Convertible Preferred Stock, which we refer to as the Trigger Date, the Base Conversion Price will be reduced to the lowest of (i) the Base Conversion Price, as adjusted and (ii) 80% of the average of the volume weighted average prices of our common stock for the 10 trading days following the reverse split or Trigger Date, as applicable.
Subject to limited exceptions, a holder of shares of Series B-1 Convertible Preferred Stock will not have the right to convert any portion of its Series B-1 Convertible Preferred Stock if the holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of our common stock outstanding immediately after giving effect to its conversion.
Certain NASDAQ continued listing standards limit the number of securities that may be issued in a particular offering. Accordingly, without prior shareholder approval (the “Stockholder Approval”), common stock may not be issued upon the conversion of the Series B-1 Convertible Preferred Stock, or upon conversion or exercise of preferred stock and warrants issued in connection with the sale of the Series B-1 Convertible Preferred Stock, if such conversion or exercise would result in aggregate issuances by us of common stock in excess of 6,333,041 shares.
15

Forced Conversion
If, after the Stockholder Approval has been obtained and after the earlier of the reverse split or the Trigger Date, the volume weighted average price of our common stock exceeds $1.00 (as adjusted) for at least 20 consecutive trading days and the daily dollar trading volume during such period exceeds $100,000 per trading day, we have the right to require conversion of any or all of the outstanding shares of Series B-1 Convertible Preferred Stock into common stock at the then-current conversion price.
Dividends
The Series B-1 Convertible Preferred Stock is entitled to receive dividends (on an “as converted to common stock” basis) to and in the same form as dividends actually paid on shares of our common stock. No other dividends will be paid on shares of Series B-1 Convertible Preferred Stock.
Liquidation
Upon any liquidation, dissolution or winding up of the Company after payment or provision for payment of debts and other liabilities of the Company, but before any distribution or payment is made to the holders of any junior securities, the holders of Series B-1 Convertible Preferred Stock shall be entitled to be paid out of the assets of the Company available for distribution to its stockholders an amount equal to $1,000 per share plus accrued but unpaid dividends, after which any remaining assets of the Company shall be distributed among the holders of the other class or series of stock in accordance with the Company’s Certificate of Incorporation.
Series B-2 Convertible Preferred Stock
General
There are currently 500 shares of Series B-2 Convertible Preferred Stock outstanding, and we do not currently expect to issue any additional shares of Series B-2 Convertible Preferred Stock in the future. Under our Certificate of Incorporation, as amended, our Board of Directors is authorized, without further stockholder action, to provide for the issuance of up to 10,000,000 shares of preferred stock, par value $0.0001 per share, in one or more series, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations and restrictions thereof. By the filing of a Certificate of Designations with the Secretary of State of the State of Delaware, we designated 500 shares of our authorized but unissued preferred stock as a series of our preferred stock, designated as Series B-2 Convertible Preferred Stock, of which 500 shares have been issued. The terms of the Series B-2 Convertible Preferred Stock are substantially identical to the terms of the Series B-1 Convertible Preferred Stock.
Series C Convertible Preferred Stock
General
Our Certificate of Incorporation authorizes 10,000,000 shares of preferred stock. Our board of directors is authorized, without further stockholder action, to establish various series of preferred stock from time to time and to determine the rights, preferences and privileges of any unissued series including, among other matters, any dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms, the number of shares constituting any such series, and the description thereof and to issue any such shares. Our Board has designated [] shares of preferred stock as Series C Convertible Preferred Stock. As of March [], 2013, there were no shares of Series C Convertible Preferred Stock outstanding. Although there is no current intent to do so, our board of directors may, without stockholder approval, issue shares of an additional class or series of preferred stock with voting and conversion rights which could adversely affect the voting power of the holders of the common stock or the Series C Convertible Preferred Stock, except as prohibited by the certificate of designation of the Series C Convertible Preferred Stock.
Liquidation Preference
The Series C Convertible Preferred Stock ranks, with respect to rights upon liquidation, winding-up or dissolution, (1) senior to common stock, (2) senior to any series of preferred stock ranked junior to the Series C Convertible Preferred Stock, (3) junior to the Series B-1 Convertible Preferred Stock and Series B-2 Convertible Preferred Stock and (4) junior to all existing and future indebtedness of the Company.
16

Voting Rights
Except as required by law, holders of the Series C Convertible Preferred Stock do not have rights to vote on any matters, questions or proceedings, including the election of directors. However, as long as any shares of Series C Convertible Preferred Stock are outstanding, we will not, without the affirmative vote of the holders of 50.1% or more of the then outstanding shares of the Series C Convertible Preferred Stock, (1) alter or change adversely the powers, preferences or rights given to the Series C Convertible Preferred Stock or alter or amend the certificate of designation, (2) authorize or create any class of stock ranking as to dividends, redemption or distribution of assets upon liquidation senior to, or otherwise pari passu with, the Series C Convertible Preferred Stock, (3) amend our certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series C Convertible Preferred Stock, (4) increase the number of authorized shares of Series C Convertible Preferred Stock, or (5) enter into any agreement with respect to any of the foregoing.
Delaware Law
Notwithstanding certain protections in the certificate of designation for holders of Series C Convertible Preferred Stock, Delaware law also provides holders of preferred stock with certain rights. The holders of the outstanding shares of Series C Convertible Preferred Stock will be entitled to vote as a class upon a proposed amendment to the certificate of incorporation if the amendment would:
●  increase or decrease the aggregate number of authorized shares of Series C Convertible Preferred Stock;
●  increase or decrease the par value of the shares of Series C Convertible Preferred Stock; or
●  alter or change the powers, preferences, or special rights of the shares of Series C Convertible Preferred Stock so as to affect them adversely.
Redemption
We will have the right to redeem the Series C Convertible Preferred Stock for a cash payment equal to 120% of the stated value of the Series C Convertible Preferred Stock. Holders of Series C Convertible Preferred Stock will receive 20 trading days prior notice of any redemption and will have the ability to convert the Series C Convertible Preferred Stock into common stock during this notice period.
Conversion
Subject to certain ownership limitations as described below, the Series C Convertible Preferred Stock is convertible at any time at the option of the holder into shares of our common stock at a conversion ratio determined by dividing the stated value of the Series C Convertible Preferred Stock (or $1,000) by a conversation price of $[] per share. The conversion price is subject to adjustment in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. In addition, until such time that for at least 20 trading days during any 30 consecutive trading days, the volume weighted average price of our common stock exceed [] of the initial conversion price and the average daily dollar trading volume during such period exceeds $150,000 per trading day, if we sell or grant any option to purchase or sell any common stock or common stock equivalents entitling any person to acquire shares of common stock at an effective price per share that is lower than the Base Conversion Price, then the conversion price shall be reduced to equal the Base Conversion Price. Subject to limited exceptions, a holder of shares of Series C Convertible Preferred Stock will not have the right to convert any portion of its Series C Convertible Preferred Stock if the holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of our common stock outstanding immediately after giving effect to its conversion.

INDEMNIFICATION
Legal Matters
The validity of the shares of common stock offered hereby and certain other legal matters will be passed upon for us by Smith, Anderson, Blount, Dorsett, Mitchell & Jernigan, LLP, Raleigh, North Carolina.

Experts
Cherry Bekaert LLP (formerly “Cherry, Bekaert & Holland, L.L.P.”), our independent registered public accounting firm, has audited our financial statements included in our Annual Report on Form 10-K, for the year ended April 30, 2012, filed on July 25, 2012, which is incorporated by reference in this prospectus.  Our financial statements are incorporated by reference in reliance on their report given upon their authority as experts in accounting and auditing.
Disclosure of Commission Position on Indemnification for Securities Act Liabilities
Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances.
Our Certificate of Incorporation and Bylaws provide that our directors and officers will be indemnified by us to the fullest extent authorized by Delaware General Corporation Law. In addition, the Certificate of Incorporation provides, as permitted by Section 102(b)(7) of the Delaware General Corporation Law, that our directors will not be liable for monetary damages to us for breaches of their fiduciary duty as directors, unless they (i) violated their duty of loyalty to us or our stockholders, (ii) acted, or failed to act, in good faith, (iii) acted with intentional misconduct, (iv) knowingly or intentionally violated the law, (v) authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or (vi) derived an improper personal benefit from their actions as directors.
Our Bylaws also permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware General Corporation Law would permit indemnification. We have purchased a policy of directors’ and officers’ liability insurance that insures our directors and officers.
The limitations of liability and indemnification provisions in our Certificate of Incorporation and Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit our stockholders and us. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced directors and officers.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors, officers andor persons controlling persons, orthe registrant pursuant to the extent any offoregoing provisions, the selling security holders are entitled to indemnification under their agreements with us, we haveregistrant has been advised that, in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.

LEGAL MATTERS

Certain legal matters relating

In the event that a claim for indemnification against such liabilities, other than the payment by us of expenses incurred or paid by such director, officer or controlling person in the successful defense of any action, suit or proceeding, is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

CONSOLIDATED CONDENSED STATEMENTS OF CASH FLOWS - CONTINUED

Non-cash financing activities during the three months ended July 31, 2008:

(1)The Company issued 1,375,530 shares of common stock for the conversion of notes payable with a gross carrying value of $339,756, at a conversion price of $0.247 per share. These notes included discounts totaling $319,135, and thus had a net carrying value of $20,621. The unamortized discounts of $319,135 were recognized as interest expense upon conversion.

(2)As further discussed in Note 4, the Company entered into a license agreement in May 2008 with Virginia Commonwealth University (“Licensor”) whereby the Company obtained certain rights in connection with three of the Licensor’s patents. The purchase price of these licensing rights totaled $369,728, which included a $16,228 cash payment by the Company plus the issuance of five-year warrants to purchase 500,000 shares of common stock at $0.42 per share. These warrants were valued at $353,500. In connection with the license agreement, the Company also paid the Licensor $50,000 as a deposit towards future royalties.

(3)During the first quarter 2008, the Company received a total of $2,147,714 from the exercise of warrants. Due to errors made by the Company in the pricing of certain warrant exercise transactions, $140,000 of this total is owed back to the related investors. The Company has included this obligation in current liabilities. Additionally, the Company is owed $12,500 for a similar warrant exercise pricing error with another investor. This amount has been expensed as a bad debt, as the Company does not intend to take further action to collect this receivable.

Non-cash financing activities during the three months ended July 31, 2007:

(1)In connection with the issuance of $132,979 of two-year notes payable, the Company recorded discounts on notes payable related to the original issue discount of $7,979, and additional discounts of $37,984 related to the relative fair value of 1,329,787 warrants issued in the transaction.

(2)The Company made principal payments on its convertible notes payable of $36,000 through the issuance of 470,246 shares of common stock.

(3)The Company recorded debt issue costs of $72,638 of which $56,681 was non-cash through the issuance of 1,329,787 warrants for capital raising services.

Part II Information Not Required in the opinion of management, are necessary to present fairly the financial position of the Company as of July 31, 2008, and the results of its operations for the three months ended July 31, 2008 and 2007, and for the period from May 26, 1967 (inception) to July 31, 2008, and its cash flows for the three months ended July 31, 2008 and 2007, and for the period from May 26, 1967 (inception) to July 31, 2008. Certain information and footnote disclosures normally included in financial statements have been condensed or omitted pursuant to rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”). The Company believes that the disclosures in the financial statements are adequate to make the information presented not misleading. However, the financial statements included herein should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended April 30, 2008 filed with the Commission on August 13, 2008.

The accompanying consolidated condensed 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 financial statements, the Company is in the development stage and, at July 31, 2008, has an accumulated deficit of $41,989,577, continues to sustain operating losses on a monthly basis, and expects to incur operating losses for the foreseeable future. The Company requires substantial additional funds to complete clinical trials and pursue regulatory approvals. Although management believes that the Company has necessary working capital to fund operations in fiscal year 2008-2009, management is actively seeking additional sources of equity and/or debt financing; however, there is no assurance that any additional funding will be available.

In view of the matters described above, recoverability of a major portion of the recorded asset amounts shown in the accompanying July 31, 2008 balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to generate cash from future operations. 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 recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

2. RECENT ACCOUNTING PRONOUNCMENTSProspectus

In May 2008, the FASB issued Statement of Financial Accounting Standards No. 162, “The Hierarchy of Generally Accepted Accounting Principles” (“SFAS 162”). SFAS 162 identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles in the United States. SFAS 162 will become effective 60 days following Securities and Exchange Commission (“SEC”) approval of the Public Company Accounting Oversight Board (PCAOB) amendments to AU Section 411, “The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles.” The Company does not anticipate the adoption of SFAS 162 to have a material impact on its results of operations, financial position, or cash flows.

2. RECENT ACCOUNTING PRONOUNCMENTS (CONTINUED)

In June 2008, the FASB issued Staff Position No. EITF 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities” (“FSP EITF 03-6-1”). FSP EITF 03-6-1 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting, and therefore, need to be included in the earnings allocation in calculating earnings per share under the two-class method described in FASB Statement of Financial Accounting Standards No. 128, “Earnings Per Share.” FSP EITF 03-6-1 requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings per shared. FSP EITF 03-6-1 is effective for fiscal years beginning after December 15, 2008. FSP EITF 03-6-1 is effective for the Company in the quarter ending July 31, 2009. The Company is currently assessing the impact of FSP EITF 03-6-1, but does not expect that such adoption will have a material effect on its results of operations, financial position, or cash flows.

3. STOCK-BASED COMPENSATION

The fair value of the Company’s stock options is determined using a Black-Scholes option pricing model, consistent with the provisions of SFAS No. 123R (“Share-Based Payment”) and Securities and Exchange Commission Staff Accounting Bulletin No. 107 (“SAB 107”). The fair value of stock options granted is recognized as compensation expense over the requisite service period. Compensation expense for all share-based payment awards is recognized using the straight-line single-option method. Effective May 1, 2006, the Company adopted SFAS No 123R, using a modified prospective application. Prior to May 1, 2006, the Company measured employee and board member compensation cost under the intrinsic method provided by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”) whereby compensation expense is recognized for the excess, if any, of the fair value of the Company’s common stock over the option price on the date the option is granted.

The Company uses the historical stock price volatility to value stock options within the Black-Scholes option pricing model. The expected term of stock options represents the period of time options are expected to be outstanding and is based on observed historical exercise patterns for the Company, which management believes are indicative of future exercise behavior. For the risk free interest rate, the Company uses the observed interest rates appropriate for the term that the options are expected to be outstanding.

The Company’s net loss for the three months ended July 31, 2008 and 2007 includes approximately $68,000 and $11,000 of non-cash stock-based compensation costs. As of July 31, 2008, there was approximately $71,000 of total unrecognized compensation cost related to non-vested share-based compensation arrangements.

The fair value of each option grant during the three months ended July 31, 2008 was estimated at the grant date using the Black-Scholes option pricing model using the following assumptions: an average risk-free interest rate of 3.95%; average volatility of 105.34%; zero dividend yield for all years; expected life of 10 years; and an estimated forfeiture rate of 14.8%. There were no option grants during the three months ended July 31, 2007.

4. LICENSING RIGHTS

In May 2008, the Company entered into a license agreement with Virginia Commonwealth University (“Licensor”) whereby Oxygen Biotherapeutics obtained a worldwide, exclusive license to valid claims under three of the Licensor’s patent applications that relate to methods for non-pulmonary delivery of oxygen to tissue and the products based on those valid claims used or useful for therapeutic and diagnostic applications in humans and animals. The license includes the right to sub-license to third parties. The term of the agreement is the life of the patents covered by the patent applications, except that we can terminate the agreement at any time on not less than 90 days advance notice.

(UNAUDITED)

4. LICENSING RIGHTS (CONTINUED)

The Company has an obligation to diligently pursue product development and pursue, at its expense, prosecution of the patent applications covered by the agreement. The Company paid an initial fee of $50,000 in cash and paid an additional $16,228 to the Licensor as reimbursement of costs paid by the Licensor on patent applications and related work. The Company also issued to the licensor a warrant for the purchase of 500,000 shares of common stock at an exercise price of $0.42 per share that expires May 22, 2013. These warrants were valued at $353,500.

The $50,000 initial fee is fully credited towards future royalty or sublicensing revenue payments to the Licensor. This fee has been accounted for as a deposit and is included in other assets at July 31, 2008.

The $16,228 reimbursement costs and the $353,500 value of the 500,000 warrants discussed above were capitalized as licensing rights and are being amortized over a period of ten years. Accumulated amortization on the licensing rights at July 31, 2008 totaled $8,720.

The Company agreed to pay to the Licensor a royalty on net sales of licensed products as follows:

Net Sales

Applicable Royalty

Up to $10 million

25%

Over $10 million to $49 million

15%

Over $49 million

10%

The Company also agrees to pay to the Licensor a percentage of sublicensing revenue received from sub-licensees or other third parties in regards to the licensed patents, equal to 33% of any such third party payments, which may be reduced to 25% if the Company completes pre-clinical studies on a licensed product, reduced further to 20% if the Company completes Phase I clinical studies, reduced further to 17% if the Company completes Phase II clinical studies, and reduced further to 10% if the Company completes Phase III clinical studies on a licensed product.

The Company agreed to pay a $20,000 annual maintenance fee to the Licensor, starting in May 2009 and payable in each following May as long as the agreement is in force. The maintenance fee payments will be fully credited towards future royalty or sublicensing revenue payments to the Licensor.

The Company agreed to pay a $50,000 annual minimum royalty to the Licensor, starting in May 2009 and payable in each following May as long as the agreement is in force. The minimum royalty fee payments will be fully credited towards future royalty or sublicensing revenue payments to the Licensor.

Lastly, the agreement provides that the Company will make the following minimum milestone payments to the Licensor, with respect to the first licensed product to achieve each milestone. However, if new licensed products are separately patentable, the same milestone payments shall apply to them.

5. STOCKHOLDERS’ EQUITY

During the three months ended July 31, 2008:

(1)The Company issued 1,375,530 shares of common stock for the conversion of convertible notes with a gross carrying value of $339,756, at a conversion price of $0.247 per share. These convertible notes included discounts totaling $319,135, and thus had a net carrying value of $20,621. The unamortized discounts of $319,135 were recognized as interest expense upon conversion.

(2)Pursuant to the exercise of warrants, the Company issued 7,845,000 shares and received a total of $2,147,714. Due to errors made by the Company in the pricing of certain warrant exercise transactions, $140,000 of this total is owed back to the related investors. The Company has included this obligation in current liabilities. Additionally, the Company is owed $12,500 for a similar warrant exercise pricing error with another investor. This amount has been expensed as a bad debt, as the Company does not intend to take further action to collect this receivable.

(3)The Company issued 42,000 shares of its common stock as compensation to its Chief Executive Officer, valued at $34,300.

On June 17, 2008, the stockholders of the Company approved the amendment of the Company’s 1999 Stock Plan to increase the number of shares of common stock available for awards under the plan from 4,000,000 to 12,000,000, increase the maximum number of shares covered by awards granted under the plan to an eligible participant from 4,000,000 shares to 5,000,000 shares, and make additional technical changes to update the plan. Persons eligible to receive grants under the Plan consist of all of the Company’s employees (including executive officers and employee directors), non-employee directors, and consultants and advisors who perform services for the Company.

The following table summarizes the Company’s stock warrant information during the quarter ended July 31, 2008:

As of July 31, 2008, potentially issuable shares of common stock included 7,925,000 options, 121,334,919 warrants, and 80,528,972 conversion shares. Diluted earnings per share for the quarter ended July 31, 2008 was calculated assuming exercise of the above options and warrants and conversion of all of the outstanding convertible debt as of the beginning of the quarter. Upon conversion of the debt to common stock it is assumed that the Company would recognize $23,837,474 in additional interest expense for the write off of the related debt discounts and debt issuance costs, less $857,367 in discount and issuance cost amortization expense that would be eliminated in the conversion.

6. RELATED PARTY TRANSACTIONS

During the three months ended July 31, 2008, the Company paid $39,245 in severance payments to Robert Nicora, a former President and Chief Executive Officer of the Company.

As of July 31, 2008 the Company had approximately $63,994 payable to current and former directors of the Company.

7. INCOME TAXES

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109.” Interpretation No. 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The evaluation of a tax position in accordance with Interpretation No. 48 involves determining whether it is more likely than not that a tax position will be sustained upon examination, based upon the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. If a tax position does not meet the more-likely-than-not recognition threshold, the financial statements do not recognize a benefit for that position.

As required, the Company adopted Interpretation No. 48 during the quarter ended July 31, 2007. The adoption did not result in a material impact to the Company’s results of operations or its financial condition.

The Company is subject to taxation in the U.S. and a small number of state jurisdictions. The material jurisdictions subject to potential examination by taxing authorities include the U.S. and California.

From time to time, the Company may be assessed interest or penalties by its tax jurisdictions, although any such assessments historically have been minimal and immaterial to the Company’s financial results. In the event the Company has received an assessment for interest and/or penalties, it has been classified in the financial statements as general and administrative expense.

The utilization of net operating loss carryforwards will likely be limited based on past and future issuances of common and preferred stock due to the ownership change provisions of Internal Revenue Code Section 382.

8. COMMITMENTS AND CONTINGENCIES

Employment Agreements— Effective March 25, 2008, Dr. Chris J. Stern, the Company’s Chairman of the Board, was appointed to the office of Chief Executive Officer and will retain his position as Chairman. At the time Mr. Stern was elected to the Board in November 2007 and appointed Chairman, the Company agreed to pay to Mr. Stern’s consulting firm a monthly fee of $15,000 for consulting services that Mr. Stern provides to the Company.

On February 1, 2000 the Board of Directors approved a two-year employment contract with Richard Kiral, as Vice President of Product Development. Mr. Kiral’s current base annual salary is $167,000 for the year ending April 2008 and includes an automobile allowance, medical and dental coverage, participation in the Executive Bonus Plan, $200,000 life insurance payable by the corporation and payable to a beneficiary named by the insured, and options granted for 75,000 shares annually. The contract will renew automatically annually unless terminated by either party. Mr. Kiral’s employment agreement provides that he is to receive a minimum severance payment equal to 9 months of his annual salary period in the event of a change in control as defined. Effective March 25, 2008, the Board appointed Dr. Richard M. Kiral to serve as President and Chief Operating Officer of the Company. Pursuant to an agreement executed on March 26, 2008, Dr. Kiral’s employment agreement with the Company has been amended to provide for payment of a sum equal to Dr. Kiral’s annual base salary and performance bonus upon

Dr. Kiral’s termination without cause, as that term is defined in the employment agreement. Furthermore, the Board has increased Dr. Kiral’s monthly compensation by $6,000 and has agreed to (i) to issue to Dr. Kiral an aggregate of 20,000 options to purchase shares of the Company’s common stock, at a price to be determined, on the 1st of every month, commencing with April 1, 2008, for so long as Dr. Kiral serves on the Board, and (ii) to issue and pay to Dr. Kiral, upon his termination as a board member by the Company for whatever reason, with or without cause, an aggregate of 100,000 shares of the Company’s common stock and the sum of $200,000, payable upon such termination.

Effective November 20, 2007, Robert W. Nicora, the Company’s President, Chief Executive Officer and Chief Financial Officer resigned from all officer positions and from his directorship. In accordance with his employment agreement, Mr. Nicora is entitled to receive a total amount of $378,233 which includes accrued salaries, repayment of advances and severance payments. A total of $39,245 was paid on this obligation during the current quarter, and the remaining balance due to Mr. Nicora as of July 31, 2008 was $48,994.

Consulting Agreement—On May 5, 2008 the Company entered into a consulting agreement with Fiona International SA for the provision of consulting services concerning licensing of the Company’s Oxycyte product and other corporate matters. The agreement was effective through August 4, 2008, and involved the following remuneration: (a) Cash payments during the current quarter totaling $87,500; (b) the issuance of 3,032,000 five year common stock purchase warrants with an exercise price of $0.247 during the current quarter; (c) and the issuance of 411,250 shares of common stock on August 1, 2008. At July 31, 2008, the Company’s obligation on this agreement totaled $205,770, and is included in current liabilities.

Other Agreements—The Company has entered into agreements with its two of its Board members and a consultant whereby it will grant 3-year options for a total of 900,000 shares at an exercise of price of $0.30 per share in the event the Company enters into a license agreement, undergoes a change of control, or is sold.

Registration Requirement—Warrants totaling 49,410,844 and convertible notes with a face amount of $20,256,472 and conversion shares totaling 82,010,008 issued during the year ended April 30, 2008 are subject to a requirement that the Company file a registration statement with the SEC to register the underlying shares, and that it be declared effective on or before January 9, 2009. In the event that the Company does not have an effective registration statement as of that date, or if at some future date the registration ceases to be effective, then the Company is obligated to pay liquidated damages to each holder in the amount of 1% of the aggregate market value of the stock, as measured on January 9, 2009 or at the date the registration statement ceases to be effective. As an additional provision for non-registration of the shares, the holders would also receive the option of a cashless exercise of their warrant or conversion shares.

The agreement underlying the issue of the above warrants (“Warrant Agreement”) asserts that, prior to September 30, 2008, the Company is required to take action to submit to the shareholders of the Company a proposal to amend the Company’s articles of incorporation to increase the number of authorized shares of common stock by such amount as is necessary to reserve for issuance the maximum aggregate number of warrant shares then issued or potentially issuable in the future upon exercise of the Warrant Agreement. As a result of the June 30, 2008 merger (further described in Note 9), this action was completed and the number of authorized common shares was increased from 200 million common shares, par value $0.01, to 400 million common shares, par value $0.0001.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Oxygen Biotherapeutics, Inc.

We have audited the accompanying balance sheets of Oxygen Biotherapeutics, Inc., formerly Synthetic Blood International, Inc. (a development-stage enterprise) (the “Company”) as of April 30, 2008 and 2007, and the related statements of operations, stockholders’ equity and cash flows for each of the years ended April 30, 2008 and 2007, and for the period from inception, May 26, 1967, through April 30, 2008. 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. The Company’s statements of operations, stockholders’ equity and cash flows for the period from inception, May 26, 1967, through April 30, 2003, were audited by other auditors whose report, dated June 30, 2003, included an explanatory paragraph regarding substantial doubt about the Company’s ability to continue as a going concern. The financial statements for the period from inception, May 26, 1967, through April 30, 2003, reflect cumulative net losses of $18,700,730. The other auditors’ report has been previously furnished to us, and our opinion expressed herein, insofar as it relates to the amounts for such prior periods, is based solely on the report of other auditors.

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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits 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 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 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, and the report of the other auditors, provide a reasonable basis for our opinion.

In our opinion, based on our audits, and the report of other auditors, the financial statements referred to above present fairly, in all material respects, the financial position of Oxygen Biotherapeutics, Inc., formerly Synthetic Blood International, Inc. as of April 30, 2008 and 2007, and the results of its operations and its cash flows for each of the years ended April 30, 2008 and 2007, and for the period from inception, May 26, 1967, through April 30, 2008, in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. The Company is a development stage enterprise presently generating no revenues, has a significant deficit accumulated during the development stage, and requires substantial additional funds to complete clinical trials and pursue regulatory approvals. In view of these matters, recoverability of a major portion of the recorded asset amounts shown in the accompanying April 30, 2008 balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to generate cash from future operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans concerning these matters are described in Note A. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

April 30, 2008 and 2007

NOTE A—DESCRIPTION OF BUSINESS AND GOING CONCERN

Description of Business—Oxygen Biotherapeutics (the Company) was originally formed as a New Jersey corporation in 1967 under the name Rudmer, David & Associates, Inc., and subsequently changed its name to Synthetic Blood International, Inc. On June 17, 2008, the stockholders of Synthetic Blood International approved the Agreement and Plan of Merger dated April 28, 2008, between Synthetic Blood International and Oxygen Biotherapeutics, Inc., a Delaware corporation. Oxygen Biotherapeutics was formed on April 17, 2008, by Synthetic Blood International to participate in the merger for the purpose of changing the state of domicile of Synthetic Blood International from New Jersey to Delaware. Certificates of Merger were filed with the states of New Jersey and Delaware, and the merger was effective June 30, 2008. Under the Plan of Merger, Oxygen Biotherapeutics is the surviving corporation and each share of Synthetic Blood International common stock outstanding on June 30, 2008, was converted to one share of Oxygen Biotherapeutics common stock.

The Company was inactive through September 1990, when it began conducting operations for the purpose of developing a synthetic blood emulsion to act as a human blood substitute, and a method of using a perfluorocarbon compound to facilitate oxygen exchange for individuals with respiratory distress syndrome. The Company is also developing an implantable, continuous reading glucose biosensor to be used primarily by individuals with diabetes. The Company submitted an Investigational New Drug Application (IND) for Oxycyte, the Company’s alternative to transfused blood for use in surgical and similar medical situations, to the Food and Drug Administration (FDA) in 2003 and successfully conducted a Phase I safety clinical study in the fourth quarter of 2003. The results of the Phase I study were consistent with the results of preclinical animal safety studies, and showed a good safety profile for Oxycyte. The Company started Phase II clinical trials of Oxycyte in surgical patients in the fourth quarter of 2004. The protocol was successfully completed in 2006 and filed in April 2008. Fluorovent, an oxygen exchange fluid for facilitating the treatment of lung conditions, and the glucose biosensor are at the preclinical development stage, and are currently inactive, awaiting additional financing. The Company has not generated significant revenues since inception.

The accompanying consolidated financial statements include the accounts and transactions of Oxygen Biotherapeutics, Inc. and Synthetic Blood International, Inc. All material intercompany transactions and balances have been eliminated in consolidation.

Going Concern—Management believes the accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplate continuation of the Company as a going concern. The Company has an accumulated deficit during the development stage of $37,741,362 at April 30, 2008 and used cash in operations of $2,276,209 during the year ended April 30, 2008. The Company requires substantial additional funds to complete clinical trials and pursue regulatory approvals. Although management believes that the Company has necessary working capital to fund operations in fiscal year 2008-2009, management is actively seeking additional sources of equity and/or debt financing; however, there is no assurance that any additional funding will be available.

In view of the matters described above, recoverability of a major portion of the recorded asset amounts shown in the accompanying April 30, 2008 balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company’s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to generate cash from future operations. 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 recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.

NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Development Stage—The Company has not commenced its planned principal operations, and has not earned significant revenues, therefore it is considered a “Development Stage Enterprise.”

Cash and Cash Equivalents—The Company considers all highly liquid instruments with a maturity date of three months or less, when acquired, to be cash equivalents.

(A Development Stage Enterprise)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

April 30, 2008 and 2007

Cash Concentrations—The Company maintains cash balances at financial institutions, which may at times, exceed the amounts insured by the Federal Deposit Insurance Corporation (“FDIC”) of $100,000 per institution. The Company’s cash and cash equivalents included balances uninsured by the FDIC of approximately $278,000 at April 30, 2008. A total of $4,576,563 of the Company’s cash is invested in the UBS Select Prime Institutional Money Market Fund which has an average maturity of 53 days and is rated AAA by Moody’s and Standard and Poor’s. These funds included balances uninsured by the Securities Investor Protection Corporation of approximately $4,076,000.

Property and Equipment—Property and equipment are recorded at cost. Depreciation and amortization are computed using the straight-line method over the shorter of the estimated useful lives of the related assets, ranging from three to ten years, or the lease term, if applicable.

Impairment of Long-Lived Assets—The Company accounts for its long-lived assets in accordance with Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (“SFAS 144”). SFAS 144 requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical cost carrying value of an asset may no longer be appropriate. The Company assesses recoverability of the carrying value of an asset by estimating the future net cash flows expected to result from the asset, including eventual disposition of the asset. If the future net cash flows are less than the carrying value of the asset, an impairment loss is recorded equal to the difference between the asset’s carrying value and the fair value or disposable value. During the year ended April 30, 2008, the Company incurred impairment charges totaling $32,113 on a piece of laboratory equipment due to infrequency of use.

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

Loss Per Share—Basic loss per share, which excludes antidilutive securities, is computed by dividing loss available to common shareholders by the weighted-average number of common shares outstanding for that particular period. In contrast, diluted loss per share considers the potential dilution that could occur from other equity instruments that would increase the total number of outstanding shares of common stock. Potentially dilutive securities, however, have not been included in the fiscal year 2007 diluted loss per share computation because their effect is antidilutive. If such shares were included in diluted EPS, they would have resulted in weighted-average common shares of approximately 204.8 million in fiscal year 2007, respectively. Such amounts include shares potentially issuable under outstanding options, warrants and convertible debentures.

Income Taxes—Deferred tax assets and liabilities are recorded for differences between the financial statement and tax bases of the assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is recorded for the amount of income tax payable or refundable for the period increased or decreased by the change in deferred tax assets and liabilities during the period.

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

Fair Value of Financial Instruments—The Company’s balance sheet includes the following financial instruments: cash and cash equivalents, short-term notes payable, and convertible debentures. The Company considers the carrying amount of its cash and cash equivalents and short-term notes payable to approximate fair value due to the short-term nature of these instruments It is not practicable for the Company to estimate the fair value of its convertible debentures as such estimates cannot be made without incurring excessive costs. The significant terms of the Company’s convertible debentures are described in Note D. At April 30, 2008 the debentures had a gross carrying value of $20,256,242, with an original issue discount totaling $11,155,401.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

April 30, 2008 and 2007

Employee Stock Options and Stock-Based Compensation —Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards (“SFAS”) No. 123(R), “Share Based Payment,” using a modified prospective application. Earlier periods were not restated. SFAS No. 123(R) is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation” and supersedes Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”). SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values.

Prior to adopting SFAS No. 123(R), as permitted, the Company elected to follow APB 25 in accounting for its employee stock options. According to APB 25, no compensation expense was recognized since the exercise price of the Company’s stock options generally equaled the market price of the underlying stock on the date of grant. The Company transitioned to SFAS No. 123 by utilizing SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure” (“SFAS No. 148”). In accordance with SFAS No. 148, the Company disclosed the effects of stock-based employee compensation on reported net income or loss and earnings or loss per share in the footnotes to its annual and interim financial statements.

Given that the Company previously followed APB 25 and SFAS No. 148 in accounting for its employee stock options, the impact of adopting the expense recognition requirements of SFAS 123(R) was significant to the Company’s results of operations, but not its financial position. The Company’s net loss for the years ended April 30, 2008 and 2007 includes approximately $769,000 and $53,000 of non-cash stock-based employee compensation costs, respectively.

The Company continues to follow EITF Issue 96-18, “Accounting for Equity Instruments that are Issued to Other than Employees for Acquiring, or in Conjunction with Selling Goods and Services,” for stock options and warrants issued to consultants and other non-employees. In accordance with EITF Issue 96-18, these stock options and warrants issued as compensation for services to be provided to the Company are accounted for based upon the fair value of the services provided or the estimated fair market value of the option or warrant, whichever can be more clearly determined. The Company recognizes this expense over the period in which the services are provided. The Company’s net loss for the years ended April 30, 2008 and 2007 includes expenses of approximately $4,782,000 and $2,019,000, respectively, for non-cash stock-based compensation for options issued to consultants and other non-employees.

Recent Accounting Pronouncements

SFAS 157—In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”), which defines fair value, establishes a framework for measuring fair value in GAAP, and expands disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. SFAS 157 was originally effective for fiscal years beginning after November 15, 2007, but was partially delayed by one year for non-financial assets and liabilities as detailed within FASB Staff Position 157-2. The Company is currently evaluating SFAS 157 and FASB Staff Position 157-2, and does not believe these pronouncements will materially affect its financial position or results of operations.

SFAS 159—In February 2007, the FASB issued SFAS 159,The Fair Value Option for Financial Assets and Financial Liabilities Including an Amendment of FASB Statement No. 115(“SFAS 159”), which permits entities to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is effective as of the beginning of fiscal years after November 15, 2007. The Company adopted SFAS 159 on May 1, 2008, and does not believe it will materially affect its financial position or results of operations.

SFAS No. 141(R)—In December 2007, the FASB issued Statement No. 141(R),Business Combinations. This Statement replaces FASB Statement No. 141,Business Combinations. This Statement retains the fundamental requirements in Statement 141 that the acquisition method of accounting (which Statement 141 called thepurchase method) be used for all business combinations and for an acquirer to be identified for each business combination. This Statement defines the acquirer as the entity that obtains control of one or more businesses in the business combination and establishes the acquisition date as the date that the acquirer achieves control. Statement 141 did not define the acquirer, although it included guidance on identifying the acquirer, as does this Statement. This Statement’s scope is broader than that of

OXYGEN BIOTHERAPEUTICS, INC.

(A Development Stage Enterprise)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

April 30, 2008 and 2007

Statement 141, which applied only to business combinations in which control was obtained by transferring consideration. By applying the same method of accounting – the acquisition method – to all transactions and other events in which one entity obtains control over one or more other businesses, this Statement improves the comparability of the information about business combinations provided in financial reports. This Statement applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. An entity may not apply it before that date. The Company is currently evaluating SFAS 141(R), and has not yet determined its potential impact on its future results of operations or financial position.

SFAS No. 160—In December 2007, the FASB issued Statement No. 160,Noncontrolling Interests in Consolidated Financial Statements – an Amendment of ARB No. 51. This Statement amends ARB 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. Before this Statement was issued, limited guidance existed for reporting noncontrolling interests. As a result, considerable diversity in practice existed. So-called minority interests were reported in the consolidated statement of financial position as liabilities or in the mezzanine section between liabilities and equity. This Statement improves comparability by eliminating that diversity. This Statement is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. Earlier adoption is prohibited. The effective date of this Statement is the same as that of the related Statement 141(R). This Statement shall be applied prospectively as of the beginning of the fiscal year in which this Statement is initially applied, except for the presentation and disclosure requirements. The presentation and disclosure requirements shall be applied retrospectively for all periods presented. The Company is currently evaluating SFAS 160 and has not yet determined its potential impact on its future results of operations or financial position.

SFAS No. 161—In March 2008, the FASB issued SFAS No. 161,“Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133.” SFAS No. 161 requires enhanced disclosures about an entity’s derivative and hedging activities. These enhanced disclosures will discuss (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for under Statement 133 and its related interpretations, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The Company has not determined the impact, if any SFAS No. 161 will have on its financial statements.

NOTE C—PATENTS

The Company’s intangible assets consist of expenditures associated with patents related to the Company’s various technologies. Capitalized costs include amounts paid to third parties for legal fees, application fees and other direct costs incurred in the filing and prosecution of patent applications. These assets are amortized on a straight-line method over their estimated useful lives, which range from eight to ten years. The Company reviews these intangible assets for impairment in accordance with SFAS No. 144,Accounting for the Impairment or Disposal of Long-Lived Assets. During the year ended April 30, 2008, management believes no indications of impairment existed.

NOTE D—NOTES PAYABLE

Fiscal Year 2008:

In July and August 2007, the Company issued $282,055 of 2-year notes payable for working capital needs. The notes were unsecured and were issued with an original issue discount of $16,417, and additional discounts of $67,969 related to the relative fair value of 2,815,763 warrants issued in the transaction. Of the total discounts of $84,386, $26,230 was amortized into interest and the remaining balance of $58,156 was included in the loss on debt extinguishment. The Company recorded debt issuance costs of $170,686, of which $120,223 was through the issuance of 1,431,000 warrants and $50,463 was paid in cash for capital raising services.

In November and December 2007, the Company received $1,000,000 from the issuance of short term bridge loans to fund operations and other working capital needs. The notes were unsecured and paid interest at 10% per year. In addition, the Company issued 5-year warrants to purchase 2,500,000 shares of common stock at $0.245 per share to investors. An additional discount of $288,750 was recorded for the relative fair value of the warrants. In connection with the bridge financing, the Company issued 2,500,000 warrants for capital raising services and recorded debt issue costs of $288,750 which represents the fair value of these warrants.

In December 2007, the Company exchanged its $1,000,000 bridge loans for 5-year convertible debentures with a face amount of $2,222,222. The notes are unsecured, convertible into shares of common stock at $0.247 per share, and were issued with a 55% original issue discount totaling $1,222,222. In addition, the Company issued 5-year warrants to purchase 4,498,426 shares of common stock at $0.247 per share to investors. Additional discounts of $703,554 and $296,446 were recorded for the relative fair values of the warrants and beneficial conversion feature, respectively. The Company incurred no debt extinguishment costs in this exchange.

In January 2008, the Company exchanged its remaining outstanding short term loans for 5-year convertible debentures with a face amount of $3,982,545. The notes are unsecured, convertible into shares of common stock at $0.247 per share, and were issued with a 55% original issue discount totaling $2,190,400. In addition, the Company issued 5-year warrants to purchase 8,061,831 shares of common stock at $0.247 per share to investors. Additional discounts of $1,035,945 and $756,200 were recorded for the relative fair values of the warrants and beneficial conversion feature, respectively. Pursuant to this exchange transaction, the Company recorded a debt extinguishment loss of $191,941. The Company determined that the exchange of notes should be accounted for as complete debt extinguishment as opposed to a debt modification, pursuant to the guidance in EITF 02-04 and EITF 96-19. The key components of this determination were as follows: (a) no concessions were granted to the Company by the existing note holders; and (b) the modification of terms was deemed substantial enough to be treated as an extinguishment, since the present value of the new notes exceeded the present value of the exchanged notes by more than 10%.

Effective November 20, 2007, Robert W. Nicora, the Company’s President, Chief Executive Officer and Chief Financial Officer resigned from all officer positions and from his directorship. In accordance with his employment agreement, Mr. Nicora is entitled to receive a total amount of $378,233 which includes accrued salaries, repayment of advances and severance payments. A total of $289,994 was paid on this obligation during the period from November 20, 2007 to April 30, 2008.

Robert J. Larsen, a member of the Company’s Board of Directors and its former interim President and Chief Executive Officer, died unexpectedly on March 24, 2008. On March 25, 2008, the Board of Directors approved the issuance of options to the Estate of Robert J. Larsen to purchase 300,000 shares of common stock at an exercise price of $0.30 per share.

Other Agreements—The Company has entered into agreements with its two of its Board members and a consultant whereby it will grant 3-year options for a total of 900,000 shares at an exercise of price of $0.30 per share in the event the Company enters into a license agreement, undergoes a change of control, or is sold.

Registration Requirement—Warrants totaling 49,410,844 and convertible notes issued during the year ended April 30, 2008 are subject to a requirement that the Company file a registration statement with the SEC to register the underlying shares, and that it be declared effective on or before January 9, 2009. In the event that the Company does not have an effective registration statement as of that date, or if at some future date the registration ceases to be effective, then the Company is obligated to pay liquidated damages to each holder in the amount of 1% of the aggregate market value of the stock, as measured on January 9, 2009 or at the date the registration statement ceases to be effective. As an additional remedy for non-registration of the shares, the holders would also receive the option of a cashless exercise of their warrant or conversion shares.

The agreement underlying the issue of the above warrants (“Warrant Agreement”) asserts that, prior to September 30, 2008, the Company is required to take action to submit to the shareholders of the Company a proposal to amend the Company’s articles of incorporation to increase the number of authorized shares of common stock by such amount as is necessary to reserve for issuance the maximum aggregate number of warrant shares then issued or potentially issuable in the future upon exercise of the Warrant Agreement. As a result of the June 30, 2008 merger (further described in Note K), this action was completed and the number of authorized common shares was increased from 200 million common shares, par value $0.01, to 400 million common shares, par value $0.0001.

In the exchange of its remaining outstanding short term loans for 5-year convertible debentures with a face amount of $3,982,545, the Company issued 5-year warrants to purchase 8,061,831 shares of common stock at $0.247 per share to investors. Discounts of $1,035,945 and $756,200 were recorded for the relative fair values of the warrants and beneficial conversion feature, respectively.

In connection with the Company’s $6,335,000 financing as described in Note D, the Company recorded discounts of $4,864,998 related to the relative fair value of the 28,497,501 5-year warrants to purchase common stock at $0.247 per share, and $1,470,002 for the relative fair value of the beneficial conversion feature. The Company also incurred total costs of $5,510,562 for capital raising services on these transactions. The costs of the capital raising services include a $369,215 paid in cash, $768,337 for the fair value of 2,088,272 restricted shares of common stock, and $4,373,010 for the fair value of 21,853,086 warrants.

In March 2008, the Company issued 760,000 warrants to a noteholder as compensation for the Company’s failure to issue the proper amount of warrants and provide an adequate exercise term in the original 2006 issuance. These warrants have a 3-year term and are exercisable at $0.245 per share. Interest expense of $329,137 was recorded for the fair value of these warrants.

The Company made principal payments on its convertible notes payable with a net carrying value of $130,000 through the issuance of 1,333,887 shares of common stock.

In April 2008, the Company issued 14,000 shares of its common stock as compensation to its Chief Executive Officer, valued at $12,460.

As further described in Note E, warrants totaling 41,057,783 and convertible notes issued during the year ended April 30, 2008 are subject to a requirement that the Company file a registration statement with the SEC to register the underlying shares, and that it be declared effective on or before January 9, 2009. EITF 00-19 provides guidance to proper recognition, measurement, and classification of certain freestanding financial instruments that are indexed to, and potentially settled in, any entity’s own stock. If an issuer does not control the form of settlement, an instrument is classified as an asset or liability. An issuer is deemed to “control the settlement” if it has both the contractual right to settle in equity shares and the ability to deliver equity shares. EITF 00-19 states that the existence of a contractual requirement for the issuer to deliver registered shares is one of the conditions that is considered outside the control of the issuer. However, the Financial Accounting Standards Board issued a FASB Staff Position on EITF 00-19-2,Accounting for Registration Payment Arrangements (“FSP EITF 00-19-2”) in December 2006. The FSP specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement, should be separately recognized and measured in accordance with FASB Statement No. 5, Accounting for Contingencies. Pursuant to the guidance in EITF 00-19 and FSP EITF 00-19-2, the Company has accounted for the warrants as equity instruments in the accompanying financial statements.

The Company determined that the conversion feature embedded in the convertible debentures satisfied the definition of a conventional convertible instrument under the guidance provided in ETIF 00-19 and ETIF 05-02, as the conversion option’s value may only be realized by the holder by exercising the option and receiving a fixed number of shares. As such, the embedded conversion option in the notes payable qualifies for equity classification under ETIF 00-19, qualifies for the scope exception of paragraph 11(a) of SFAS 133, and is not bifurcated from the host contract. In accordance with the provisions of Accounting Principles Board Opinion No. 14, the Company allocated the net proceeds received in this transaction to each of the convertible debentures and common stock purchase warrants based on their relative estimated fair values. In accordance with the consensus of EITF issues 98-5 and 00-27, management determined that the convertible debentures contained a beneficial conversion feature based on the effective conversion price after allocating proceeds of the convertible debentures to the common stock purchase warrants. The amounts recorded for the original issue discount, common stock purchase warrants and the beneficial conversion feature are amortized as interest expense over the terms of the convertible debentures.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

April 30, 2008 and 2007

Fiscal Year 2007:

The Company made principal payments on convertible debentures issued in 2006 of $335,216 through the issuance of 3,265,740 shares of common stock for the year ended April 30, 2007. At April 30, 2007, 590,914 shares were convertible by the note holders under the debenture agreements at $0.22 per share, and all of these conversions were made during fiscal year 2008.

The Company determined that the conversion feature embedded in the notes payable satisfied the definition of a conventional convertible instrument under the guidance provided in ETIF 00-19 and ETIF 05-02, as the conversion option’s value may only be realized by the holder by exercising the option and receiving a fixed number of shares. As such, the embedded conversion option in the notes payable qualifies for equity classification under ETIF 00-19, qualifies for the scope exception of paragraph 11(a) of SAFS 133, and is not bifurcated from the host contract. In accordance with the provisions of Accounting Principles Board Opinion No. 14, the Company allocated the net proceeds received in this transaction to each of the convertible debentures and common stock purchase warrants based on their relative estimated fair values. As a result, the Company allocated $770,000 to the convertible debentures and $525,000 to the common stock purchase warrants, which was recorded in additional paid-in-capital. In accordance with the consensus of EITF issues 98-5 and 00-27, management determined that the convertible debentures contained a beneficial conversion feature based on the effective conversion price after allocating proceeds of the convertible debentures to the common stock purchase warrants. Because the calculated beneficial conversion amount exceeded the remaining net carrying value of the convertible debentures, the beneficial conversion was recorded in an amount equal to the remaining net carrying value of the convertible debentures of $770,000 with a corresponding amount recorded as additional paid-in-capital. The amounts recorded for the original issue discount, common stock purchase warrants and the beneficial conversion feature are amortized as interest expense over the terms of the convertible debentures.

The shares underlying the convertible debentures and warrants are subject to a registration rights agreement that requires the Company to effect a registration statement and then maintain the effectiveness of the registration statement for a defined period of time. If the Company fails to comply with the related contractual terms, then liquidated damages penalties accrue to the Company in an amount not to exceed 20% of the investors’ investment. Management believes that such penalties reasonably represent the difference between the value of a registered share and an unregistered share of the Company’s common stock, and therefore, the Company has accounted for the warrants as equity instruments in the accompanying financial statements pursuant to the guidance in EITF 00-19 and FSP EITF 00-19-2.

NOTE G—STOCK OPTIONS AND WARRANTS

In September 1999, the Company’s Board of Directors approved the 1999 Stock Plan (the “1999 Plan”) which provides for the granting of incentive and nonstatutory stock options to employees, directors and consultants to purchase up to 4,000,000 shares of the Company’s common stock. The 1999 Plan was approved by stockholders on October 10, 2000. Options granted under the 1999 Plan are exercisable at various dates up to four years and have expiration periods of generally ten years. As of April 30, 2008, the Company had 3,345,000 qualified stock options outstanding under the 1999 Plan. In addition, the Company has 4,490,000 non-qualified stock options outstanding as of April 30, 2008. All options granted in the three fiscal years ended April 30, 2008 were granted at fair market value. As of April 30, 2008, there were 655,000 options available for grant under the 1999 Plan.

Effective May 1, 2006, the Company adopted the provisions of SFAS No. 123R, “Share-Based Payment,” which establishes accounting for share-based instruments exchanged for employee services. Under the provisions of SFAS No. 123R, share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an

expense over the employee’s requisite service period (generally the vesting period of the equity grant). Prior to May 1, 2006, the Company accounted for share-based compensation to employees in accordance with APB No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. The Company also followed the disclosure requirements of SFAS No. 123, “Accounting for Stock-Based Compensation,” as amended by SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure.” The Company elected to employ the modified prospective transition method as provided by SFAS No. 123R and, accordingly, financial statement amounts for the prior periods presented have not been restated to reflect the fair value method of expensing share-based compensation. For the year ended April 30, 2008, the Company recorded share-based compensation expense of approximately $769,000. The adoption of SFAS No. 123R did not affect cash flow.

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the paragraph below. The Company uses historical data among other factors to estimate the expected volatility, the expected option life, and the expected forfeiture rate. The risk-free rate is based on the interest rate paid on a U.S. Treasury issue with a term similar to the estimated life of the option.

The fair value of each option grant was estimated at the grant date using the Black-Scholes option-pricing model using the following assumptions: an average risk-free interest rate of 2.8% for 2008 and 4.7% for 2007; average volatility of 94% for 2008 and 101% for 2007; zero dividend yield for all years; and expected life of 3-10 years.

The estimated weighted average fair value of options granted during the years ended April 30, 2008 and 2007 was $0.32 and $0.12, respectively

In June 2006, The FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109.” Interpretation No. 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with SFAS 109. This Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Interpretation No. 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Interpretation No. 48 is effective for fiscal years beginning after December 15, 2006. The cumulative effect, if any, of applying the Interpretation is to be reported as an adjustment to the opening balance of retained earnings in the year of adoption. The impact of the Company’s reassessment of its tax positions in accordance with Interpretation No. 48 did not have an effect on the Company’s results of operations, financial condition or liquidity. As of April 30, 2008, the Company does not have any unrecognized tax benefits related to various federal and state income tax matters. The Company will recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense.

The Company is subject to U.S. federal income tax as well as income tax of multiple state tax jurisdictions. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service for the years ending April 30, 2005 through 2007. The Company’s state income tax returns are open to audit under the statute of limitations for the years ended April 30, 2005 through 2007. The Company does not anticipate any material amount of unrecognized tax benefits within the next 12 months.

ITEM 14.INDEMNIFICATION OF DIRECTORS AND OFFICERS

Oxygen Biotherapeutics’ Charter provides that, to the fullest extent that limitations on the liability

Section 145 of directors and officers are permitted by the Delaware General Corporation Law (the “DGCL”), no director or officer of Oxygen Biotherapeutics shall have any liability to Oxygen Biotherapeutics or its stockholders for monetary damages. The DGCL provides that a corporation’s charter may includecorporation has the power to indemnify a provision which restrictsdirector, officer, employee or limits the liabilityagent of its directors or officers to the corporation or its stockholders for money damages except: (1) toand certain other persons serving at the extent that it is provided that the person actually received an improper benefit or profit in money, property or services, for the amountrequest of the benefit or profitcorporation in money, property or services actually received, or (2) to the extent that a judgment or other final adjudication adverse to the person is entered in a proceeding based on a finding in the proceeding that the person’s action, or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. Oxygen Biotherapeutics’ Charter and Bylaws provide that Oxygen Biotherapeutics shall indemnify and advance expenses to its currently acting and its former directors to the fullest extent permitted by the DGCL and that Oxygen Biotherapeutics shall indemnify and advance expenses to its officers to the same extent as its directors and to such further extent as is consistent with law.

The Charter and Bylaws provide that Oxygen Biotherapeutics will indemnify its directors and officers and may indemnify employees or agents of Oxygen Biotherapeutics to the fullest extent permitted by lawrelated capacities against liabilitiesamounts paid and expenses incurred in connection with litigation in which they may be involved because of their offices with Oxygen Biotherapeutics. However, nothing in the Charteran action or Bylaws of Oxygen Biotherapeutics protects or indemnifies a director, officer, employee or agent against any liabilityproceeding to which he would otherwiseis or is threatened to be subjectmade a party by reason of willful misfeasance, badsuch position, if such person shall have acted in good faith gross negligenceand in a manner he reasonably believed to be in or reckless disregardnot opposed to the best interests of the duties involvedcorporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the conductcase of his office. Toactions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that a director or officer has been successful in defense of any proceeding, our Bylaws providethe adjudicating court determines that he shall be indemnified against reasonable expenses incurred in connection therewith.

Oxygen Biotherapeutics maintains an officer’s and director’s liability insurance policy insuring its officers and directors against certain liabilities and expenses incurred by them in their capacities as such and insuringindemnification is proper under the Oxygen Biotherapeutics under certain circumstances, in the event that indemnification payments are made to such officers and directors.

The foregoing summaries are necessarily subject to the complete text of the statute, thecircumstances.

Our Certificate of Incorporation and Bylaws provide that our directors and officers will be indemnified by us to the fullest extent authorized by Delaware General Corporation Law. In addition, the Certificate of Incorporation provides, as permitted by Section 102(b)(7) of the Delaware General Corporation Law, that our directors will not be liable for monetary damages to us for breaches of their fiduciary duty as directors, unless they (i) violated their duty of loyalty to us or our stockholders, (ii) acted, or failed to act, in good faith, (iii) acted with intentional misconduct, (iv) knowingly or intentionally violated the law, (v) authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or (vi) derived an improper personal benefit from their actions as directors.
Our Bylaws also permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware General Corporation Law would permit indemnification. We have purchased a policy of directors’ and officers’ liability insurance that insures our directors and officers.
The limitations of liability and indemnification provisions in our Certificate of Incorporation and Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit our stockholders and us. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, the insurance and the indemnity agreements are qualifiednecessary to attract and retain talented and experienced directors and officers.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in their entirety by reference thereto.

the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

2)  That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
3)  To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
4)  That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or
ii.if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness.
