ITEM 1—BUSINESS

Tenax Therapeutics 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.  Effective June 30, 2008, we changed the domiciliary state of the corporation to Delaware and changed the company name to Oxygen Biotherapeutics, Inc. On September 19, 2014, we changed the company name to Tenax Therapeutics, Inc.

Tenax Therapeutics, Inc. is a specialty pharmaceutical company focused on identifying, developing and commercializing products for the critical care market. On November 13, 2013, through our wholly owned subsidiary, Life Newco, Inc., or Life Newco, we acquired a license granting Life Newco an exclusive, sublicenseable right in the United States and Canada to develop and commercialize pharmaceutical products containing levosimendan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial, for use in the reduction of morbidity and mortality in cardiac surgery patients at risk for developing Low Cardiac Output Syndrome, or LCOS. We initiated a Phase III trial with levosimendan in that indication and activated the initial sites during the third quarter of calendar year 2014.

We were previously developing Oxycyte®, a systemic perfluorocarbon, or PFC, product we believed to be a safe and effective oxygen carrier for use in situations of acute ischemia. In addition, we previously developed a family of perfluorocarbon-based oxygen carriers for use in personal care, topical wound healing, and other topical indications. During 2014, we suspended the development of these PFC products while we evaluate strategic alternatives for future development and commercialization of these product candidates.

On April 9, 2015, our Board of Directors approved a change in our fiscal year to a fiscal year beginning on January 1 and ending on December 31 of each year, such change beginning as of January 1, 2016.  This form 10-KT is a transition report and includes financial information for May 1, 2015 to December 31, 2015, or the Transition Period 2015.  For comparative purposes, an unaudited consolidated statement of operations and comprehensive income have been included for May 1, 2014 to December 31, 2014, or the Transition Period 2014. The Transition Period 2014 has not been audited and is derived from our books and records.  In the opinion of management, the Transition Period 2014 reflects all adjustments necessary to present the financial position and results of operations in accordance with generally accepted accounting principles.  Prior to the year-end change, our fiscal year ended on April 30 of each year.

Business Strategy

Our principal business objective is to identify, develop, and commercialize novel therapeutic products for disease indications that represent significant areas of clinical need and commercial opportunity. The key elements of our business strategy are outlined below.

Efficiently conduct clinical development to establish clinical proof of concept with our lead product candidates. Levosimendan represents novel therapeutic modalities for the treatment of LCOS, septic shock and other critical care conditions. We are conducting clinical development with the intent to establish proof of concept in a number of important disease areas where these therapeutics would be expected to have benefit. Our focus is on conducting well-designed studies to establish a robust foundation for subsequent development, partnership and expansion into complementary areas.

Efficiently explore new high potential therapeutic applications, leveraging third-party research collaborations and our results from related areas.  Our product candidates have shown promise in multiple disease areas. We are committed to exploring potential clinical indications where our therapies may achieve best-in-class profile, and where we can address significant unmet medical needs. In order to achieve this goal, we have established collaborative research relationships with investigators from research and clinical institutions and our strategic partners. These collaborative relationships have enabled us to cost effectively explore where our product candidates may have therapeutic relevance, and how it may be utilized to advance treatment over current clinical care. Additionally, we believe we will be able to leverage clinical safety data and preclinical results from some programs to support accelerated clinical development efforts in other areas, saving substantial development time and resources compared to traditional drug development.

Continue to expand our intellectual property portfolio. Our intellectual property is important to our business and we take significant steps to protect its value. We have ongoing research and development efforts, both through internal activities and through collaborative research activities with others, which aim to develop new intellectual property and enable us to file patent applications that cover new applications of our existing technologies or product candidates.

Enter into licensing or product co-development arrangements in certain areas, while out-licensing opportunities in non-core areas. In addition to our internal development efforts, an important part of our product development strategy is to work with collaborators and partners to accelerate product development, reduce our development costs, and broaden our commercialization capabilities. We believe this strategy will help us to develop a portfolio of high quality product development opportunities, enhance our clinical development and commercialization capabilities, and increase our ability to generate value from our proprietary technologies.

Our Current Programs

Levosimendan Background

Levosimendan was discovered and developed by Orion Pharma, a Finnish company. Levosimendan is a calcium sensitizer/K-ATP activator developed for intravenous use in hospitalized patients with acutely decompensated heart failure. It is currently approved in over 60 countries for this indication and not available in the United States or Canada. It is estimated that to date over 1,000,000 patients have been treated worldwide with levosimendan.

Levosimendan is a novel, first in class calcium sensitizer/K-ATP activator. The therapeutic effects of levosimendan are mediated through:

●   Increased cardiac contractility by calcium sensitization of troponin C, resulting in a positive inotropic effect which is not associated with substantial increases in oxygen demand.

●   Opening of potassium channels in the vasculature smooth muscle, resulting in a vasodilatory effect on all vascular beds.

●   Opening of mitochondrial potassium channels in cardiomyocytes, resulting in a cardioprotective effect.

4

This triple mechanism of action helps to preserve heart function during cardiac surgery. Several studies have demonstrated that levosimendan protects the heart and improves tissue perfusion while minimizing tissue damage during cardiac surgery.

In 2013, we acquired certain assets of Phyxius Pharma, Inc., or Phyxius, including its North American rights to develop and commercialize levosimendan in the United States and Canada.

In 2014, we initiated a Phase III trial (LEVO-CTS) to investigate the safety and efficacy of pre-operative administration of levosimendan treatment to reduce the mortality and morbidity in cardiac surgery patients at risk for developing LCOS.  The Phase III trial is being conducted under a United States Food and Drug Administration, or FDA, approved Special Protocol Assessment, or SPA, and with FDA granted Fast Track status for the development of levosimendan in cardiac surgery patients at risk of LCOS.

We announced a collaboration with Imperial College London in August of 2014 which provided supplemental funding to support the accelerated enrollment and completion of the ongoing LeoPARDS Trial (Levosimendan for the Prevention of Acute oRgan Dysfunction in Sepsis). The LeoPARDS trial is designed to determine whether levosimendan reduces the incidence and severity of acute organ dysfunction in adult patients who have septic shock, as well as evaluate its safety profile.

Levosimendan Development for Cardiac Surgery Patients

Levosimendan is under development in North America for reduction in morbidity and mortality of cardiac surgery patients at risk of LCOS.  We have the exclusive rights in the United States and Canada to develop and commercialize intravenous levosimendan.

The FDA has granted Fast Track status for the development of levosimendan to reduce mortality and morbidity in cardiac surgery patients at risk of LCOS and has agreed to an SPA which represents agreement with the Phase III clinical trial’s study protocol.  The FDA has also provided guidance that a single successful trial will be sufficient to support approval of levosimendan in this indication. Pursuant to our license to levosimendan, we are required to use the “Simdax®” trademark to commercialize this product.

Substantial published scientific research indicates that levosimendan may provide important benefits to cardiac surgery patients, including 35 published prospectively designed clinical trials and multiple published meta-analyses. Many of these publications indicate that levosimendan provides substantial mortality and or morbidity benefits to cardiac surgery patients, particularly those at risk of developing LCOS.

LCOS is generally defined as a patient’s inability to maintain a cardiac index >2.2 L/min/m2 and hence requiring use of inotropic agents and/or mechanical assist devices such as an intra-aortic balloon pump or a left ventricular assistance device. LCOS in the cardiac surgery setting is reported to occur in 5-10% of patients undergoing cardiac surgery and is associated with 10-15 fold higher mortality or severe sequelae as a result of poor organ perfusion.

Currently, no pharmacologic therapies are approved for management or prevention of post-cardiotomy LCOS. While conventional inotropes are used to manage cardiac hemodynamics in the peri-operative setting, none have been shown to improve outcomes.

The LEVO-CTS trial design has been guided by the published literature, including important dosing refinements and inclusion of patients with low preoperative ejection fraction. In addition, we have relied heavily on the input of European clinicians who have significant personal clinical experience with the use of levosimendan in treating cardiac surgery patients.

5

Current data in cardiac surgery suggest that levosimendan is superior to traditional inotropes (dobutamine, phosphodiesterase [PDE]-inhibitors) as it achieves:

●   sustained hemodynamic improvement;

●   diminished myocardial injury;

●   improved tissue perfusion;

●   better outcomes and fewer hospital days;

●   effects most favorable in patients with low left ventricular ejection fraction (LVEF) (< 40%); and

●   opportunity to initiate therapy pre-operatively due to increased cardiac contractility without increasing intracellular calcium, without increasing oxygen consumption, or affecting cardiac rhythm and relaxation.

We have selected Duke University’s Duke Clinical Research Institute, or DCRI, to conduct the Phase III trial of levosimendan. DCRI is the world’s largest academic clinical research organization, with substantial experience in conducting cardiac surgery trials. The Phase III trial is being conducted in approximately 60-70 major cardiac surgery centers in North America. The trial is enrolling patients undergoing coronary artery bypass graphs, or CABG, and/or mitral valve surgery, and CABG with aortic valve surgery who are at risk for developing LCOS. The trial is designed as a double blind, randomized, placebo controlled study seeking to enroll 760 patients. Enrollment began in the third quarter of calendar year 2014, and will take approximately twenty-four months to complete. The protocol of the Phase III trial has been submitted to ClinicalTrials.gov.

Levosimendan Development for Septic Shock Patients

Septic shock is a serious life-threatening condition with high unmet medical need.  Despite widespread adoption of international sepsis treatment guidelines, patients often experience acute organ dysfunction typically resulting in prolonged ICU care and hospitalization.  Mortality in these patients can be as high as 30-50%.  Data from the Agency for Healthcare Research and Quality indicate that inpatient stays for sepsis exceed 1,500,000 annually in the United States and ICD-9 codes indicate that as many 400,000-500,000 of these patients progress to septic shock.

Small clinical studies suggest that levosimendan may provide important benefits to septic shock patients in the form of improved cardiac function, renal function, organ perfusion, and mitochondrial function.

●   Evidence that Levosimendan Improves Cardiac Function in Septic Shock Patients.  Results from a small trial of 28 patients with septic shock and echocardiographically proven acute left ventricular dysfunction indicate that levosimendan improved several parameters of cardiac function (Morelli 2005).  Similar improvements in right ventricular function have been reported in a randomized placebo controlled trial of 35 patients that evaluated the use of levosimendan in patients suffering from septic shock and acute respiratory distress syndrome (Morelli 2006). Other similar studies have demonstrated levosimendan improvements in microcirculatory flow (Morelli 2010), improved hemodynamics with reduced requirements for additional catecholamines (Alhashemi 2009) and improvements in cardiac output and mixed venous oxygen saturation (Vaitsis 2009).

●   Evidence that Levosimendan Improves Renal Function in Septic Shock Patients.  In a study of 28 patients with septic shock levosimendan increased creatinine clearance by 64% compared to dobutamine (Morelli 2005). Similarly, a retrospective analysis of 99 patients with septic shock who received levosimendan within 36 hours of admission to the ICU (Morelli 2009), showed levosimendan-treated patients demonstrated a 24% increase in glomerular filtration rate at 96 hours together with a reduced peak serum creatinine, when compared to matched controls.

●   Evidence that Levosimendan Improves Splanchnic/ Liver Perfusion.  One trial of 28 septic shock patients indicated that levosimendan compared to dobutamine increase gastric mucosal blood flow (Morelli 2005).   Another trial of 30 patients showed improved hepatic perfusion as measured by indocyanine green clearance, with levosimendan compared to dobutamine (Memis 2012).

6

●   Evidence that Levosimendan Improves Mitochondrial Function.  A study of 26 septic shock patients provides evidence that the unique K-ATP channel mechanism of levosimendan may protect mitochondria from the significant oxidative stress that can occur in septic shock patients (Morelli 2014).

To date, no randomized controlled trials have been large enough to determine if levosimendan may reduce mortality in septic shock patients. However, a 2015 meta-analysis of several small trials conducted by Zangrillo et al concluded that levosimendan reduced mortality in patients with severe sepsis and septic shock.

The LeoPARDS Trial is designed to evaluate the efficacy and safety of levosimendan in septic shock patients. The trial plans to enroll a total of 516 patients across approximately 35 clinical trial sites in the UK.  While the LeoPARDS trial was not designed by us, we expect to learn a lot about the potential utility of levosimendan in the management of septic shock once the results are available.  Furthermore, we initiated discussions with the FDA in a meeting in November 2014 to discuss the LeoPARDS trial design and to seek guidance on how the LeoPARDS trial data might be analyzed to support a regulatory filing.

Should levosimendan successfully progress in clinical testing and if it appears regulatory approval for one or more medical uses is likely, we intend to evaluate our options for commercializing the product. These options include licensing levosimendan to a third party for distribution, selling the product ourselves, or establishing some other form of strategic relationship for making and distributing levosimendan with a participant in the pharmaceutical industry. We are currently investigating and evaluating all options.

Other Products

In addition to levosimendan described above, we have previously developed Oxycyte, a PFC-based oxygen carrier, our Dermacyte® line of topical cosmetic products, which contained our PFC technology and other known cosmetic ingredients to promote the appearance of skin health and other desirable cosmetic benefits, as well as Wundecyte™, a novel gel developed under a contract agreement with a lab in Virginia that was designed to be used as a wound-healing gel.  As we have suspended the development of these PFC products while we evaluate strategic alternatives, we do not expect that Oxycyte, Dermacyte or Wundecyte constitute a material portion of our business going forward.

Suppliers

Pursuant to the terms of our license for levosimendan, Orion Corporation is our sole manufacturing source for levosimendan.

Intellectual Property

We rely on a combination of patent applications, patents, trade secrets, proprietary know-how, trademarks, and contractual provisions to protect our proprietary rights. We believe that to have a competitive advantage, we must develop and maintain the proprietary aspects of our technologies. Currently, we require our officers, employees, consultants, contractors, manufacturers, outside scientific collaborators and sponsored researchers, and other advisors to execute confidentiality agreements in connection with their employment, consulting, or advisory relationships with us, where appropriate. We also require our employees, consultants, and advisors who we expect to work on our products to agree to disclose and assign to us all inventions conceived during the work day, developed using our property, or which relate to our business.

To date, we own or in-license the rights to seven U.S. and foreign patents. In addition, we have numerous U.S. patent applications pending that are complemented by the appropriate foreign patent applications related to our product candidates and proprietary processes, methods and technologies. Our issued and in-licensed patents, as well as our pending patents, expire between 2015 and 2030.

We have:

–   three U.S. patents (5,824,703; 5,840,767; 6,167,887), and one Australian patents (759,557) pertaining to the use and application of PFCs as gas transport agents in blood substitutes and liquid ventilation with an average remaining life of approximately 2 years;

7

–   exclusive in-licenses to three fundamental gas transport patent applications that represent the core technology used in our products and product candidates (other than levosimendan) with an average remaining life of approximately 14 years; and

–   one U.S. patent (8,513,309) and numerous patent applications for treatment of several medical and dermatological conditions such as TBI, acne, burns and wounds with an average remaining life of approximately 15 years.

Our patent and patent applications include claims covering:

–   methods to treat certain diseases and conditions and for biological gas exchange;

–   therapies for burn and wound victims;

–   delivery of oxygenated PFC;

–   various formulations containing PFC; and

–   methods and compositions for controlled and sustained production and delivery of peroxide and/or oxygen for biological and industrial applications.

We have received U.S. trademark registrations for Oxycyte®, Dermacyte®, Defense Medicine® and Oxygen Biotherapeutics, Employing  O2, Preserving Life®. We have trademark applications pending for the following marks: Acnecyte™, Wundecyte™ and Vitavent™.  Simdax® is owned by Orion and is licensed to us for sales and marketing purposes in the United States and Canada.

In September 2014, we discontinued the development of our Oxycyte product candidates.  As part of the this change in business strategy, on May 5, 2015 we provided the Virginia Commonwealth University Intellectual Property Foundation (“VCUIPF”) their 90 day notice terminating the Exclusive License Agreement entered into between the two organizations, whose effective date was May 21, 2008.  The Exclusive License Agreement gave the Company exclusive rights to intellectual property that was used for the development and commercialization of Oxycyte and is therefore no longer needed. 

In addition, we own numerous domain names relevant to our business, such as www.tenaxthera.com, and others.

Competition

The pharmaceutical and biotechnology industries are intensely competitive. Many companies, including biotechnology, chemical and pharmaceutical companies, are actively engaged in activities similar to ours, including research and development of drugs for the treatment of rare medical conditions. Many of these companies have substantially greater financial and other resources, larger research and development staffs, and more extensive marketing and manufacturing organizations than we do. In addition, some of them have considerable experience in preclinical testing, clinical trials and other regulatory approval procedures. In addition, there are also academic institutions, governmental agencies and other research organizations that are conducting research in areas in which we are working. We expect to encounter significant competition for any of the pharmaceutical products we plan to develop.

LCOS: We believe the concept of using a medication preoperatively to prevent low cardiac output syndrome is novel. Because no therapies are currently approved or commonly used to prevent LCOS, our ability to succeed in the market is dependent on our ability to change the established practice paradigm, which is never an easy task. Key factors on which we will compete with regards to the development and marketing of levosimendan for the prevention of LCOS include, among others, the ability to obtain adequate efficacy data, safety data, cost effectiveness data and hospital formulary approval, as well as sufficient distribution and handling. Furthermore, while we believe the mechanism of action of levosimendan is novel, other low priced generically available products possess some similar qualities, which could present competition in the form of therapeutic substitution.

Septic Shock: Historically, pharmaceutical products developed or approved to treat sepsis or septic shock have resulted in product failures. Therefore, we believe that any product marketed for septic shock will face significant inherent market skepticism.  Key factors on which we will compete with regards to the development and marketing of levosimendan for the treatment of sepsis or septic shock include, among others, the ability to obtain adequate efficacy data, safety data, cost effectiveness data and hospital formulary approval, as well as sufficient distribution and handling.  In addition, classical inotropes such as dobutamine have been reserved as somewhat of a last resort alternative due to safety concerns.  We believe our ability to successfully compete in the market for the treatment of sepsis or septic shock will depend on our ability to both differentiate levosimendan from dobutamine and ultimately displace dobutamine which is well establish in the current treatment guidelines

8

In order to compete successfully in these and other therapeutic areas, we must develop proprietary positions in patented drugs for therapeutic markets that have not been satisfactorily addressed by conventional research strategies. Our product candidates, even if successfully tested and developed, may not be adopted by physicians over other products and may not offer economically feasible alternatives to other therapies.

Government regulation

The manufacture and distribution of levosimendan 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. 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 our medical products. 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.

Preclinical tests include evaluation of product chemistry and studies to assess the safety and effectiveness of the product and its formulation. The results of the preclinical tests are submitted to the FDA as part of the 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 preclinical 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 preclinical and clinical studies must be submitted to the FDA. 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 preclinical 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. The FDA may also require post-marketing testing, which can involve significant expense, to monitor for adverse effects.

Our regulatory strategy is to pursue Phase III clinical testing for levosimendan in the United States. We then intend to use the results of these tests to pursue FDA marketing approval of levosimendan in the United States.

Research and Development

Our research and development efforts are focused on the development and commercialization of levosimendan for its use in clinical indications, primarily LCOS. Previously, we were also focused on furthering the development and manufacture of Oxycyte for its use in clinical indications, primarily TBI, spinal cord injury, and decompression sickness. However, we have suspended the development of Oxycyte while we evaluate strategic alternatives. We spent approximately $6.5 million on research and development during the eight months ended December 31, 2015.

During each of the fiscal years ended April 30, 2015, 2014 and 2013 we spent approximately $6.7 million, $3.0 million and $2.5 million, respectively, on research and development.

Employees

We believe that our success will be based on, among other things, the quality of our clinical programs, our ability to invent and develop superior and innovative technologies and products, and our ability to attract and retain capable management and other personnel. We have assembled a high quality team of scientists, clinical development managers, and executives with significant experience in the biotechnology and pharmaceutical industries.

As of December 31, 2015, we had ten full-time employees and one part-time employee. In addition to our employees, we also use the service and support of outside consultants and advisors. None of our employees are represented by a union, and we believe relationships with our employees are good.

Financial Information by Geographic Area

For the Transition Period 2015 and the years ended April 30, 2015, 2014 and 2013, all revenues from external customers were attributed to United States customers.  As of December 31, 2015 and April 30, 2015, 2014, and 2013, all long-lived assets with a net book value were located in the United States.

ITEM 1A—RISK FACTORS

Risks Related to Our Financial Position and Need for Additional Capital

We have a limited operating history, and we expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.

Our operations, to date, have been primarily limited to organizing and staffing our company, developing our technology and undertaking preclinical studies and clinical trials of our product candidates. We have not yet obtained regulatory approvals for any of our clinical product candidates. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history.

Specifically, our financial condition and operating results have varied significantly in the past and will continue to fluctuate from quarter-to-quarter and year-to-year in the future due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include the following factors, among others:

-   our ability to obtain additional funding to develop our product candidates;

-   the need to obtain regulatory approval of our most advanced product candidates;

-   potential risks related to any collaborations we may enter into for our product candidates;

-   delays in the commencement, enrollment and completion of clinical testing, as well as the analysis and reporting of results from such clinical testing;

-   the success of clinical trials of our levosimendan product candidates or future product candidates;

-   any delays in regulatory review and approval of product candidates in development;

-   our ability to establish an effective sales and marketing infrastructure;

-   competition from existing products or new products that may emerge;

-   the ability to receive regulatory approval or commercialize our products;

-   potential side effects of our product candidates that could delay or prevent commercialization;

-   potential product liability claims and adverse events;

-   potential liabilities associated with hazardous materials;

-   our ability to maintain adequate insurance policies;

-   our dependency on third-party manufacturers to supply or manufacture our products;

-   our ability to establish or maintain collaborations, licensing or other arrangements;

-   our ability, our partners’ abilities, and third parties’ abilities to protect and assert intellectual property rights;

-   costs related to and outcomes of potential litigation;

-   compliance with obligations under intellectual property licenses with third parties;

-   our ability to adequately support future growth; and

-   our ability to attract and retain key personnel to manage our business effectively.

Due to the various factors mentioned above, and others, the results of any prior quarterly or annual periods should not be relied upon as indications of our future operating performance.

We may need additional funding and if we are unable to raise capital when needed, we would be forced to delay, reduce or eliminate our product development programs.

Developing biopharmaceutical products, including conducting preclinical studies and clinical trials and establishing manufacturing capabilities, is expensive. We expect our research and development expenses to increase in connection with our ongoing activities, particularly as we focus on and proceed with our Phase III clinical program. In addition, our expenses could increase beyond expectations if applicable regulatory authorities, including the FDA, require that we perform additional studies to those that we currently anticipate, in which case the timing of any potential product approval may be delayed. As of December 31, 2015, we had $38.2 million of cash, including the fair value of our marketable securities on hand. Based on our current operating plans, we believe that our existing cash and cash equivalents will be sufficient to fund our projected operating requirements through the calendar year 2017. We will need substantial additional capital in the future in order to complete the commercialization of levosimendan and to fund the development and commercialization of 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.

If adequate funds are not available, we may be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or to grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:

-   the scope, rate of progress and cost of our clinical trials and other research and development activities;

-   the costs and timing of regulatory approval;

-   the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

-   the effect of competing technological and market developments;

-   the terms and timing of any collaboration, licensing or other arrangements that we may establish;

-   the cost and timing of completion of clinical and commercial-scale manufacturing activities; and

-   the costs of establishing sales, marketing and distribution capabilities for our cosmetic products and any product candidates for which we may receive regulatory approval.

Risks Related to Commercialization and Product Development

We are limited in the number of products we can simultaneously pursue and therefore our survival depends on our success with a small number of product opportunities.

We have limited financial resources, so at present we are primarily focusing these resources on developing levosimendan for the treatment of low cardiac output syndrome. At present we intend to commit most of our resources to advancing levosimendan 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 Oxycyte, 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 currently have no approved drug products for sale and we cannot guarantee that we will ever have marketable drug products.

We currently have no approved drug products for sale. The research, testing, manufacturing, labeling, approval, selling, marketing, and distribution of drug products are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries, with regulations differing from country to country. We are not permitted to market our product in the United States until we receive approval of a new drug application, or an NDA, from the FDA for each product candidate. We have not submitted an NDA or received marketing approval for any of our product candidates. Obtaining approval of an NDA is a lengthy, expensive and uncertain process. Markets outside of the United States also have requirements for approval of drug candidates which we must comply with prior to marketing. Accordingly, we cannot guarantee that we will ever have marketable drug products.

11

The development of levosimendan is subject to a high level of technological risk.

We expect to devote a substantial portion of our financial and managerial resources to pursuing Phase III clinical trials for levosimendan over the next two years. The biomedical field has undergone rapid and significant technological changes. Technological developments may result in our products 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 levosimendan. As our opportunity to generate substantial product revenues within the next three to four years is most likely dependent on successful testing and commercialization of levosimendan for surgical applications, any such occurrence would have a material adverse effect on our operations and could result in the cessation of our business.

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

We expect to commit a substantial portion of our financial and business resources over the next two years to clinical testing of levosimendan and advancing this product to regulatory approval for use in one or more medical applications. All of these clinical trials and testing will be expensive and time consuming and the timing of the regulatory review process is uncertain. The applicable regulatory agencies may suspend clinical trials at any time if they believe 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 successfully or obtain FDA or other governmental or regulatory approval of our products, or that such approval, if obtained, will not include limitations on the indicated uses for which our products 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 and other governmental and regulatory approvals of our products. A significant delay in or failure of our planned clinical trials or a failure to achieve these approvals would have a material adverse effect on us and could result in major setbacks or jeopardize our ability to continue as a going concern.

The market may not accept our products.

Even if regulatory approval is obtained, there is a risk that the efficacy and pricing of our products, considered in relation to our products’ expected benefits, will not be perceived by health care providers and third-party payers as cost-effective, and that the price of our products will not be competitive with other new technologies or products. Our results of operations may be adversely affected if the price of our products are not considered cost-effective or if our products do not otherwise achieve market acceptance.

Any collaboration we enter with third parties to develop and commercialize our product candidates may place the development of our product candidates outside our control, may require us to relinquish important rights or may otherwise be on terms unfavorable to us.

We may enter into collaborations with third parties to develop and commercialize our product candidates. Our dependence on future partners for development and commercialization of our product candidates would subject us to a number of risks, including:

-   we may not be able to control the amount and timing of resources that our partners may devote to the development or commercialization of our product candidates or to their marketing and distribution;

-   partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;

-   disputes may arise between us and our partners that result in the delay or termination of the research, development or commercialization of our product candidates or that result in costly litigation or arbitration that diverts management’s attention and resources;

-   partners may experience financial difficulties;

12

-   partners may not properly maintain or defend our intellectual property rights, or may use our proprietary information, in such a way as to invite litigation that could jeopardize or invalidate our intellectual property rights or proprietary information or expose us to potential litigation;

-   business combinations or significant changes in a partner’s business strategy may adversely affect a partner’s willingness or ability to meet its obligations under any arrangement;

-   a partner could independently move forward with a competing product candidate developed either independently or in collaboration with others, including our competitors; and

-   the collaborations with our partners may be terminated or allowed to expire, which would delay the development and may increase the cost of developing our product candidates.

Delays in the enrollment and completion of clinical testing could result in increased costs to us and delay or limit our ability to obtain regulatory approval for our product candidates.

Delays in the enrollment and completion of clinical testing could significantly affect our product development costs. We do not know whether clinical trials for levosimendan will be completed on schedule, if at all. The completion of clinical trials requires us to identify and maintain a sufficient number of trial sites, many of which may already be engaged in other clinical trial programs for the same indication as our product candidates or may be required to withdraw from our clinical trial as a result of changing standards of care or may become ineligible to participate in clinical studies. The enrollment and completion of clinical trials can be delayed for a variety of other reasons, including delays related to:

-   reaching agreements on acceptable terms with prospective trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among trial sites;

-   obtaining institutional review board, or IRB, approval to conduct a clinical trial at numerous prospective sites;

-   recruiting and enrolling patients to participate in clinical trials for a variety of reasons, including meeting the enrollment criteria for our study and competition from other clinical trial programs for the same indication as our product candidates;

-   maintaining and supplying clinical trial material on a timely basis; and

-   collecting, analyzing and reporting final data from the clinical trials.

In addition, a clinical trial may be suspended or terminated by us, the FDA or other regulatory authorities due to a number of factors, including:

-   failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;

-   inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities resulting in the imposition of a clinical hold;

-   unforeseen safety issues or any determination that a trial presents unacceptable health risks; and

-   lack of adequate funding to continue the clinical trial, including unforeseen costs due to enrollment delays, requirements to conduct additional trials and studies and increased expenses associated with the services of our contract research organizations, or CROs, and other third parties.

Changes in regulatory requirements and guidance may occur and we may need to amend clinical trial protocols to reflect these changes with appropriate regulatory authorities. Amendments may require us to resubmit our clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial. If we experience delays in the completion of, or if we terminate, our clinical trials, the commercial prospects for our product candidates will be harmed, and our ability to generate product revenues will be delayed. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. Even if we are able to ultimately commercialize our product candidates, other therapies for the same or similar indications may have been introduced to the market and established a competitive advantage.

Risks Relating to Regulatory Matters

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

Our research, development, testing, manufacturing, marketing and distribution of levosimendan is, and will continue to be, subject to extensive regulation, monitoring and approval by the FDA and other regulatory agencies. 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 and other regulatory approvals;

-   adverse events could cause the FDA and other regulatory authorities to halt trials;

-   at any time the FDA and other regulatory agencies could change policies and regulations that could result in delay and perhaps rejection of our products; and

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

Post-commercialization stage

Discovery of previously unknown problems with our products, or unanticipated problems with our manufacturing arrangements, even after FDA and other regulatory approvals of our products 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 our 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, results of operations and cash flows.

The FDA and other regulatory agencies continue to review products even after they receive agency approval. If and when the FDA or another regulatory agency outside the United States approves one of our products, its manufacture and marketing will be subject to ongoing regulation, which could include compliance with current good manufacturing practices, adverse event reporting requirements and 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 levosimendan or our other products. In addition, the FDA or other regulatory agencies could withdraw a previously approved product from the market upon receipt of newly discovered information. The FDA or another regulatory agency could also require us to conduct additional, and potentially expensive, studies in areas outside our approved indicated uses.

We must continually monitor the safety of our products once approved and marketed for signs that their use may elicit serious and unexpected side effects and adverse events, which could jeopardize our ability to continue marketing the products. We may also be required to conduct post-approval clinical studies as a condition to licensing a product.

As with all pharmaceutical products, the use of our products could sometimes produce undesirable side effects or adverse reactions or events (referred to cumulatively as adverse events). For the most part, we would expect these adverse events to be known and occur at some predicted frequency. When adverse events are reported to us, we will be required to investigate each event and circumstances surrounding it to determine whether it was caused by our product and whether it implies that a previously unrecognized safety issue exists. We will also be required to periodically report summaries of these events to the applicable regulatory authorities.

In addition, the use of our products could be associated with serious and unexpected adverse events, or with less serious reactions at a greater than expected frequency. This may be especially true when our products are used in critically ill or otherwise compromised patient populations. When these unexpected events are reported to us, we will be required to make a thorough investigation to determine causality and implications for product safety. These events must also be specifically reported to the applicable regulatory authorities. If our evaluation concludes, or regulatory authorities perceive, that there is an unreasonable risk associated with the product, we would be obligated to withdraw the impacted lot(s) of that product. Furthermore, an unexpected adverse event of a new product could be recognized only after extensive use of the product, which could expose us to product liability risks, enforcement action by regulatory authorities and damage to our reputation and public image.

14

A serious adverse finding concerning the risk of our products by any regulatory authority could adversely affect our reputation, business and financial results.

When a new product is approved, the FDA or other regulatory authorities may require post-approval clinical trials, sometimes called Phase IV clinical trials. If the results of such trials are unfavorable, this could result in the loss of the license to market the product, with a resulting loss of sales.

After our products are commercialized, we expect to spend considerable time and money complying with federal and state laws and regulations governing their sale, and, if we are unable to fully comply with such laws and regulations, we could face substantial penalties.

Health care providers, physicians and others will play a primary role in the recommendation and prescription of our clinical products. Our arrangements with third-party payers and customers may expose us to broadly applicable fraud and abuse and other health care laws and regulations that may constrain the business or financial arrangements and relationships through which we will market, sell and distribute our products. Applicable federal and state health care laws and regulations are expected to include, but not be limited to, the following:

-   the federal anti-kickback statute is a criminal statute that makes it a felony for individuals or entities knowingly and willfully to offer or pay, or to solicit or receive, direct or indirect remuneration, in order to induce the purchase, order, lease, or recommending of items or services, or the referral of patients for services, that are reimbursed under a federal health care program, including Medicare and Medicaid;

-   the federal False Claims Act imposes liability on any person who knowingly submits, or causes another person or entity to submit, a false claim for payment of government funds. Penalties include three times the government’s damages plus civil penalties of $5,500 to $11,000 per false claim. In addition, the False Claims Act permits a person with knowledge of fraud, referred to as a qui tam plaintiff, to file a lawsuit on behalf of the government against the person or business that committed the fraud, and, if the action is successful, the qui tam plaintiff is rewarded with a percentage of the recovery;

-   health Insurance Portability and Accountability Act imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

-   the Social Security Act contains numerous provisions allowing the imposition of a civil money penalty, a monetary assessment, exclusion from the Medicare and Medicaid programs, or some combination of these penalties; and

-   many states have analogous state laws and regulations, such as state anti-kickback and false claims laws. In some cases, these state laws impose more strict requirements than the federal laws. Some state laws also require pharmaceutical companies to comply with certain price reporting and other compliance requirements.

Our failure to comply with any of these federal and state health care laws and regulations, or health care laws in foreign jurisdictions, could have a material adverse effect on our business, financial condition, result of operations and cash flows.

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

As a result of Patient Protection and Affordable Care Act and the Health Care and Education Affordability Reconciliation Act of 2010, collectively, the ACA, enacted in March 2010, substantial changes have occurred and are expected to continue to occur in the system for paying for health care in the United States, including changes made in order to extend medical benefits to those who currently lack insurance coverage. This comprehensive health care reform legislation also included provisions to control health care costs and improve health care quality. Together with ongoing statutory and budgetary policy developments at a federal level, this health care reform legislation could include changes in Medicare and Medicaid payment policies and other health care delivery administrative reforms that could potentially negatively impact our business. Because not all the administrative rules implementing health care reform under the legislation have been finalized, and because of ongoing federal fiscal budgetary pressures not yet resolved for federal health programs, the full impact of the ACA and of further statutory actions to reform healthcare payment on our business is unknown, but there can be no assurances that health care reform legislation will not adversely impact either our operational results or the manner in which we operate our business. Cost of care could be reduced by reducing the level of reimbursement for medical services or products (including those biopharmaceuticals that we intend to produce and market), or by restricting coverage (and, thereby, utilization) of medical services or products. In either case, a reduction in the utilization of, or reimbursement for, our products could have a materially adverse impact on our financial performance.

15

Uncertainty of third-party reimbursement could affect our future results of operations.

Sales of medical products largely depend on the reimbursement of patients’ medical expenses by governmental health care programs and private health insurers. We will be required to report detailed pricing information, net of included discounts, rebates and other concessions, to the Centers for Medicare and Medicaid Services, or CMS, for the purpose of calculating national reimbursement levels, certain federal prices, and certain federal rebate obligations. If we report pricing information that is not accurate to the federal government, we could be subject to fines and other sanctions that could adversely affect our business. In addition, the government could change its calculation of reimbursement, federal prices, or federal rebate obligations which could negatively impact us. There is no guarantee that government health care programs or private health insurers will reimburse for the sales of our products, or permit us to sell our products at high enough prices to generate a profit.

Governments outside the United States tend to impose strict price controls and reimbursement approval policies, which may adversely affect our prospects for generating revenue outside the United States.

In some countries, particularly European Union countries and Canada, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. To obtain or maintain reimbursement or pricing approval in some countries with respect to any product candidate that achieves regulatory approval, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products upon approval, if at all, is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our prospects for generating revenue, if any, could be adversely affected which would have a material adverse effect on our business and results of operations. Further, if we achieve regulatory approval of any product, we must successfully negotiate product pricing for such product in individual countries. As a result, the pricing of our products, if approved, in different countries may vary widely, thus creating the potential for third-party trade in our products in an attempt to exploit price differences between countries. This third-party trade of our products could undermine our sales in markets with higher prices.

Risks Relating to Our Dependence on Third Parties

We depend on third parties to manufacture our products.

We do not own or operate any manufacturing facilities for the commercial-scale production of our products. Instead, we rely on third party manufacturers.  For example, pursuant to the terms of our license for levosimendan, Orion Corporation is our sole manufacturing source for levosimendan.  Accordingly, our business is susceptible to disruption, and our results of operations can be adversely affected, by any disruption in supply or other adverse developments in our relationship with Orion Corporation.  If supply from Orion Corporation is delayed or terminated, or if its facilities suffer any damage or disruption, we may need to successfully qualify an alternative supplier in a timely manner in order to not disrupt our business.  If we cannot obtain an alternate manufacturer in a timely manner, we would experience a significant interruption in supply of levosimendan, which could negatively affect our financial condition, results of operations and cash flows.

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, in particular, John P. Kelley, our Chief Executive Officer, could have a material adverse effect on us. In addition, our success will depend, among other factors, on the recruitment and retention of additional highly skilled and experienced management and technical personnel. There is a risk that we will not 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, which could negatively affect our financial condition, results of operations and cash flows.

16

We have limited experience in the sale and marketing of medical products.

We have limited experience in the sale and marketing of approved medical products and marketing the licensing of such products before FDA or other regulatory approval. We have not decided upon a commercialization strategy in these areas. We do not know of any third party that is prepared to distribute our products should they be approved. If we decide to establish our own commercialization 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 commercialization program at a cost that is acceptable in relation to revenue or whether we can be successful in commercializing our product. Factors that may inhibit our efforts to commercialize our products directly and without strategic partners include:

-   our inability to recruit and retain adequate numbers of effective sales and marketing personnel;

-   the inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe our products;

-   the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and

-   unforeseen costs and expenses associated with creating and sustaining an independent sales and marketing organization.

Failure to successfully commercialize our products or to do so on a cost effective basis would likely result in failure of our business.

We may enter into distribution arrangements and marketing alliances for certain products and any failure to successfully identify and implement these arrangements on favorable terms, if at all, may impair our ability to commercialize our product candidates.

We do not anticipate having the resources in the foreseeable future to develop global sales and marketing capabilities for all of the products we develop, if any. We may pursue arrangements regarding the sales and marketing and distribution of one or more of our product candidates and our future revenues may depend, in part, on our ability to enter into and maintain arrangements with other companies having sales, marketing and distribution capabilities and the ability of such companies to successfully market and sell any such products. Any failure to enter into such arrangements and marketing alliances on favorable terms, if at all, could delay or impair our ability to commercialize our product candidates and could increase our costs of commercialization. Any use of distribution arrangements and marketing alliances to commercialize our product candidates will subject us to a number of risks, including the following:

-   we may be required to relinquish important rights to our products or product candidates;

-   we may not be able to control the amount and timing of resources that our distributors or collaborators may devote to the commercialization of our product candidates;

-   our distributors or collaborators may experience financial difficulties;

-   our distributors or collaborators may not devote sufficient time to the marketing and sales of our products; and

-   business combinations or significant changes in a collaborator’s business strategy may adversely affect a collaborator’s willingness or ability to complete its obligations under any arrangement.

We may need to enter into additional co-promotion arrangements with third parties where our own sales force is neither well situated nor large enough to achieve maximum penetration in the market. We may not be successful in entering into any co-promotion arrangements, and the terms of any co-promotion arrangements we enter into may not be favorable to us.

Risks Relating to Intellectual Property

It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.

Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of our product candidates and the methods used to manufacture them, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell or importing our products is dependent upon the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.

17

We license certain intellectual property from third parties that covers our product candidates. We rely on certain of these third parties to file, prosecute and maintain patent applications and otherwise protect the intellectual property to which we have a license, and we have not had and do not have primary control over these activities for certain of these patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. Our enforcement of certain of these licensed patents or defense of any claims asserting the invalidity of these patents would also be subject to the cooperation of the third parties.

The patent positions of pharmaceutical and biopharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in biopharmaceutical patents has emerged to date in the United States. The biopharmaceutical patent situation outside the United States is even more uncertain. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in the patents we own or to which we have a license from a third-party. Further, if any of our patents are deemed invalid and unenforceable, it could impact our ability to commercialize or license our technology.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

-   others may be able to make compositions or formulations that are similar to our product candidates but that are not covered by the claims of our patents;

-   we might not have been the first to make the inventions covered by our issued patents or pending patent applications;

-   we might not have been the first to file patent applications for these inventions;

-   others may independently develop similar or alternative technologies or duplicate any of our technologies;

-   it is possible that our pending patent applications will not result in issued patents;

-   our issued patents may not provide us with any competitive advantages, or may be held invalid or unenforceable as a result of legal challenges by third parties;

-   we may not develop additional proprietary technologies that are patentable; or

-   the patents of others may have an adverse effect on our business.

We also may rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

We rely on confidentiality agreements that, if breached, may be difficult to enforce and could have a material adverse effect on our business and competitive position.

Our policy is to enter agreements relating to the non-disclosure and non-use of confidential information with third parties, including our contractors, consultants, advisors and research collaborators, as well as agreements that purport to require the disclosure and assignment to us of the rights to the ideas, developments, discoveries and inventions of our employees and consultants while we employ them. However, these agreements can be difficult and costly to enforce. Moreover, to the extent that our contractors, consultants, advisors and research collaborators apply or independently develop intellectual property in connection with any of our projects, disputes may arise as to the proprietary rights to the intellectual property. If a dispute arises, a court may determine that the right belongs to a third party, and enforcement of our rights can be costly and unpredictable. In addition, we rely on trade secrets and proprietary know-how that we seek to protect in part by confidentiality agreements with our employees, contractors, consultants, advisors or others. Despite the protective measures we employ, we still face the risk that:

-   these agreements may be breached;

-   these agreements may not provide adequate remedies for the applicable type of breach; or

-   our trade secrets or proprietary know-how will otherwise become known.

18

Any breach of our confidentiality agreements or our failure to effectively enforce such agreements would have a material adverse effect on our business and competitive position.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to protect our rights to, or use, our technology.

If we or our partners choose to go to court to stop someone else from using the inventions claimed in our patents, that individual or company has the right to ask the court to rule that these patents are invalid and/or should not be enforced against that third party. These lawsuits are expensive and would consume time and other resources even if we were successful in stopping the infringement of these patents. In addition, there is a risk that the court will decide that these patents are not valid and that we do not have the right to stop the other party from using the inventions. There is also the risk that, even if the validity of these patents is upheld, the court will refuse to stop the other party on the ground that such other party’s activities do not infringe our rights to these patents.

Furthermore, a third party may claim that we or our manufacturing or commercialization partners are using inventions covered by the third party’s patent rights and may go to court to stop us from engaging in our normal operations and activities, including making or selling our product candidates. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and technical personnel. There is a risk that a court would decide that we or our commercialization partners are infringing the third party’s patents and would order us or our partners to stop the activities covered by the patents. In addition, there is a risk that a court will order us or our partners to pay the other party damages for having violated the other party’s patents. We have agreed to indemnify certain of our commercial partners against certain patent infringement claims brought by third parties. The biotechnology industry has produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods of use either does not infringe the patent claims of the relevant patent and/or that the patent claims are invalid, and we may not be able to do this. Proving invalidity, in particular, is difficult since it requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.

Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our issued patents or our pending applications, or that we were the first to invent the technology. Our competitors may have filed, and may in the future file, patent applications covering technology similar to ours. Any such patent application may have priority over our patent applications or patents, which could further require us to obtain rights to issued patents by others covering such technologies. If another party has filed a U.S. patent application on inventions similar to ours, we may have to participate in an interference proceeding declared by the U.S. Patent and Trademark Office to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful if, unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of our U.S. patent position with respect to such inventions.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.

Our collaborations with outside scientists and consultants may be subject to restriction and change.

We work with chemists, biologists and other scientists at academic and other institutions, and consultants who assist us in our research, development, regulatory and commercial efforts, including the members of our scientific advisory board. These scientists and consultants have provided, and we expect that they will continue to provide, valuable advice on our programs. These scientists and consultants are not our employees, may have other commitments that would limit their future availability to us and typically will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, we will be unable to prevent them from establishing competing businesses or developing competing products. For example, if a key scientist acting as a principal investigator in any of our clinical trials identifies a potential product or compound that is more scientifically interesting to his or her professional interests, his or her availability to remain involved in our clinical trials could be restricted or eliminated.

19

Under current law, we may not be able to enforce all employees’ covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.

We have entered into non-competition agreements with certain of our employees. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. Under current law, we may be unable to enforce these agreements against certain of our employees and it may be difficult for us to restrict our competitors from gaining the expertise our former employees gained while working for us. If we cannot enforce our employees’ non-compete agreements, we may be unable to prevent our competitors from benefiting from the expertise of our former employees.

We may infringe or be alleged to infringe intellectual property rights of third parties.

Our products or product candidates may infringe on, or be accused of infringing on, one or more claims of an issued patent or may fall within the scope of one or more claims in a published patent application that may be subsequently issued and to which we do not hold a license or other rights. Third parties may own or control these patents or patent applications in the United States and abroad. These third parties could bring claims against us or our collaborators that would cause us to incur substantial expenses and, if successful against us, could cause us to pay substantial damages. Further, if a patent infringement suit were brought against us or our collaborators, we or they could be forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is the subject of the suit.

If we are found to infringe the patent rights of a third party, or in order to avoid potential claims, we or our collaborators may choose or be required to seek a license from a third party and be required to pay license fees or royalties or both. These licenses may not be available on acceptable terms, or at all. Even if we or our collaborators were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations, if, as a result of actual or threatened patent infringement claims, we or our collaborators are unable to enter into licenses on acceptable terms.

There have been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical and biotechnology industries. In addition to infringement claims against us, we may become a party to other patent litigation and other proceedings, including interference proceedings declared by the United States Patent and Trademark Office and opposition proceedings in the European Patent Office, regarding intellectual property rights with respect to our products. Our products, after commercial launch, may become subject to Paragraph IV certification under the Hatch-Waxman Act, thus forcing us to initiate infringement proceedings against such third-party filers. The cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings may also absorb significant management time.

Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We try to ensure that our employees do not use the proprietary information or know-how of others in their work for us. We may, however, be subject to claims that we or these employees have inadvertently or otherwise used or disclosed intellectual property, trade secrets or other proprietary information of any such employee’s former employer. Litigation may be necessary to defend against these claims and, even if we are successful in defending ourselves, could result in substantial costs to us or be distracting to our management. If we fail to defend any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel.

Product liability lawsuits against us could cause us to incur substantial liabilities, limit sales of our existing products and limit commercialization of any products that we may develop.

Our business exposes us to the risk of product liability claims that are inherent in the manufacturing, distribution, and sale of biotechnology products. We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and an even greater risk when we commercially sell any products. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

-   decreased demand for our products and any product candidates that we may develop;

-   injury to our reputation;

-   withdrawal of clinical trial participants;

-   costs to defend the related litigation;

-   substantial monetary awards to trial participants or patients;

-   loss of revenue; and

-   the inability to commercialize any products that we may develop.

20

We currently 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. There can be no assurance that product liability insurance will be available in the future or be available on reasonable terms.

Risks Related to Owning Our Common Stock

Our share price has been volatile and may continue to be volatile which may subject us to securities class action litigation in the future.

The market price of shares of our common stock has been, and may be in the future, subject to wide fluctuations in response to many risk factors listed in this section, and others beyond our control, including:

-   actual or anticipated fluctuations in our financial condition and operating results;

-   status and/or results of our clinical trials;

-   status of ongoing litigation;

-   results of clinical trials of our competitors’ products;

-   regulatory actions with respect to our products or our competitors’ products;

-   actions and decisions by our collaborators or partners;

-   actual or anticipated changes in our growth rate relative to our competitors;

-   actual or anticipated fluctuations in our competitors’ operating results or changes in their growth rate;

-   competition from existing products or new products that may emerge;

-   issuance of new or updated research or reports by securities analysts;

-   fluctuations in the valuation of companies perceived by investors to be comparable to us;

-   share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;

-   market conditions for biopharmaceutical stocks in general;

-   status of our search and selection of future management and leadership; and

-   general economic and market conditions.

On December 31, 2015 the closing price of our common stock was $3.28, as compared to $3.42 and $4.88 as of April 30, 2015 and 2014, respectively.  During the eight months ended December 31, 2015, the lowest closing price for our common stock was $2.88 and the highest closing price was $3.81.  All stock prices are as adjusted for the 1-for-20 reverse stock split effective on May 10, 2013.

Some companies that have had volatile market prices for their securities have had securities class action lawsuits filed against them. Such lawsuits, should they be filed against us in the future, could result in substantial costs and a diversion of management’s attention and resources. This could have a material adverse effect on our business, results of operations and financial condition.

21

We are likely to attempt to raise additional capital through issuances of debt or equity securities, which may cause our stock price to decline, dilute the ownership interests of our existing stockholders, and/or limit our financial flexibility.

Historically we have financed our operations through the issuance of equity securities and debt financings, and we expect to continue to do so for the foreseeable future.  As of December 31, 2015, we had $38.2 million of cash and cash equivalents on hand. Based on our current operating plans, we believe our existing cash and cash equivalents are sufficient to continue to fund operations through the calendar year 2017. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution of their ownership interests.  Debt financing, if available, may involve restrictive covenants that limit our financial flexibility or otherwise restrict our ability to pursue our business strategies. Additionally, if we issue shares of common stock, or securities convertible or exchangeable for common stock, the market price of our existing common stock may decline. There can be no assurance that we will be successful in obtaining any additional capital resources in a timely manner, on favorable terms, or at all.

We have issued in the past, and may issue in the future, substantial amounts of instruments that are convertible into or exercisable for common stock, and our existing stockholders may face substantial dilution if such instruments are converted or exercised.

As of March 9, 2016, we had outstanding warrants and options, securities purchase agreements, and other instruments that are exercisable into an aggregate of 6,761,175 shares of our common stock, which, if exercised, would represent approximately 24% of our current outstanding common stock.  These instruments carry a wide variety of different terms and prices, and there can be no assurance as to when or whether exercises of these instruments may occur.  If all or any substantial portion of these instruments are exercised, our existing stockholders may face substantial dilution of their ownership interests. 

Risks Relating to Employee Matters and Managing Growth

We may need to increase the size of our company, and we may experience difficulties in managing growth.

As of March 9, 2016, we had 10 full-time employees. We may need to expand our managerial, operational, administrative, financial and other resources in order to manage and fund our operations and clinical trials, continue our development activities and commercialize our product candidates. To support this growth, we may hire additional employees within the next 12 months. Our management, personnel, systems and facilities currently in place may not be adequate to support this future growth. Our need to effectively manage our operations, growth and various projects requires that we continue to improve our operational, financial and management controls, reporting systems and procedures.

We may not be able to attract or retain qualified management and scientific personnel in the future. If we are unable to attract and retain necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede our achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy.

In addition, we have scientific and clinical advisors who assist us in our product development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us, or may have arrangements with other companies to assist in the development of products that may compete with ours. Because our business depends on certain key personnel and advisors, the loss of such personnel and advisors could weaken our management team and we may experience difficulty in attracting and retaining qualified personnel and advisors.

ITEM 7—MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis together with the Consolidated Financial Statements and the related notes to those statements included in “Item 8 – Consolidated Financial Statements and Supplementary Data.” This discussion contains forward-looking statements that involve risks and uncertainties. As a result of many factors, such as those set forth under “Risk Factors” and elsewhere in this Transition Report on Form 10-KT, our actual results may differ materially from those anticipated in these forward-looking statements.

Change in Fiscal Year

On April 9, 2015, our Board of Directors approved a change in our fiscal year to a fiscal year beginning on January 1 and ending on December 31 of each year, such change beginning as of January 1, 2016.  As a result of this change, financial results for the Transition Period 2015, are compared to the unaudited financial results for the Transition Period 2014.  When financial results for fiscal year 2015 and fiscal year 2014 are compared to the prior year, the results are presented on the basis of our previous fiscal year-end on a twelve month basis.

Results of operations- Comparison of the eight months ended December 31, 2015 and 2014

General and Administrative Expenses

General and administrative expenses consist primarily of compensation for executive, finance, legal and administrative personnel, including stock-based compensation. Other general and administrative expenses include facility costs not otherwise included in research and development expenses, legal and accounting services, other professional services, and consulting fees. General and administrative expenses and percentage changes for the eight months ended December 31, 2015 and 2014, respectively, are as follows:

	Eight months ended December 31,				Increase/ (Decrease)			% Increase/ (Decrease)
	2015		2014
Personnel costs	$	1,998,627	$	1,715,577	$	283,050			16	%
Legal and professional fees		1,314,303		2,166,977		(852,674	)		(39	) %
Other costs		502,345		369,193		133,152			36	%
Facilities		102,421		110,011		(7,590	)		(7	) %
Depreciation and amortization		22,935		78,084		(55,149	)		(71	) %

25

Personnel costs:

Personnel costs increased approximately $283,000 for the eight months ended December 31, 2015 compared to the same period in the prior year. The increase was due primarily to approximately $400,000 for annual bonuses accrued and the recognition of approximately $98,000 for the vesting of stock options granted during the period, partially offset by a $215,000 accrual for severance payments in the prior year paid to certain employees following the stoppage of the TBI trials.

Legal and professional fees:

Legal and professional fees consist of the costs incurred for legal fees, accounting fees, recruiting costs and investor relations services, as well as fees paid to our Board of Directors. Legal and professional fees decreased approximately $853,000 for the eight months ended December 31, 2015 compared to the same period in the prior year. This decrease was primarily due to a reduction in costs incurred for investor relations services and the vested value of stock option grants to our Board of Directors, partially offset by an increase in legal and consulting fees paid.

●   Costs associated with investor relations and communications decreased approximately $912,000 in the current period. This decrease was due primarily to the recognition of approximately $475,000 for the fair value of warrants issued to a third party investor relations firm during the same period in the prior year as well as a reduction of approximately $437,000 in fees paid in the prior year to third party investor relations firms for providing marketing and corporate communications services to us in the current period.

●   Board of Directors fees decreased in the current period by approximately $64,000. This decrease was due primarily to a reduction in the recognized expense for the vesting of stock options awarded in the current period as compared to the recognized expense for stock options awarded in the same period of the prior year.

●   Consulting costs increased approximately $87,000 due to the costs incurred for market research and commercial development services during the current period that were not incurred during the same period in the prior year.

Other costs:

Other costs include costs incurred for travel, supplies, insurance and other miscellaneous charges. The approximately $133,000 increase in other costs for the eight months ended December 31, 2015 was due primarily to an approximately $132,000 increase in franchise taxes paid, approximately $20,000 in costs incurred for our sponsorship of the National Sepsis Foundation and approximately $30,000 in legal and proxy-related data services, partially offset by a reductions of approximately $33,000 and $31,000 in travel and employee relocation costs, respectively, as compared to the same period in the prior year.

Facilities:

Facilities include costs paid for rent and utilities at our corporate headquarters in North Carolina. Facilities costs remained relatively consistent for the eight months ended December 31, 2015 and 2014.

Depreciation and Amortization:

Depreciation and amortization costs decreased approximately $55,000 for the eight months ended December 31, 2015 compared to the same period in the prior year. The decrease in costs was due primarily to amortization costs incurred in the same period of the prior year on our PFC-based intellectual property portfolio that was fully impaired as of April 30, 2015.

Research and Development Expenses

Research and development expenses include, but are not limited to, (i) expenses incurred under agreements with CROs and investigative sites, which conduct our clinical trials and a substantial portion of our pre-clinical studies; (ii) the cost of manufacturing and supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements, equipment, laboratory and other supplies. All research and development expenses are expensed as incurred. Research and development expenses and percentage changes for the eight months ended December 31, 2015 and 2014, respectively, are as follows:

26

	Eight months ended December 31,				Increase/ (Decrease)			% Increase/ (Decrease)
	2015		2014
Clinical and preclinical development	$	5,560,860	$	3,820,196	$	1,740,664			46	%
Consulting		470,335		15,231		455,104			2988	%
Personnel costs		427,873		359,129		68,744			19	%
Other costs		25,799		45,911		(20,112	)		(44	) %

Clinical and preclinical development:

Clinical and preclinical development costs include the costs associated with our Phase III and Phase II clinical trials for levosimendan and Oxycyte. The increase of approximately $1.7 million in clinical and preclinical development costs for the eight months ended December 31, 2015, compared to the same period in the prior year, was primarily due to increased expenditures for CRO costs to manage the Levo-CTS Phase III clinical trial, partially offset by a reduction in costs incurred in the current period for the development and clinical testing of Oxycyte, which development we decided to suspend in the prior year.

Levosimendan

We incurred approximately $5.5 million in research and development costs for levosimendan during the eight months ended December 31, 2015, an increase of approximately $3.1 million compared to the same period in the prior year. The increase in levosimendan development costs is due primarily to the direct costs of our Phase III Levo-CTS clinical trial for LCOS, partially offset by a reduction of approximately $500,000 in costs to support the LeoPARDS trial for septic shock that was conducted during the same period of the prior year. For the eight months ended December 31, 2015, we recorded CRO costs of approximately $5.5 million for the management of the Phase III trial which includes approximately $2.3 million in pass-through site activation and enrolled patient costs, compared to CRO costs of approximately $2.4 million during the same period in the prior year.

Oxycyte

We incurred approximately $25,000 in research and development costs for Oxycyte during the eight months ended December 31, 2015, a decrease of approximately $897,000 compared to the same period in the prior year. The decrease in Oxycyte development costs was due to our decision to suspend development of the Oxycyte product in the prior year and close out all of our sites for the Phase II-B clinical trial for TBI. We do not anticipate any significant additional costs in the future related to this clinical trial or other close-out activities related to the discontinuance of the Oxycyte product development.

Consulting fees:

Consulting fees increased approximately $455,000 for the eight months ended December 31, 2015 compared to the same period in the prior year, primarily due to an increase in fees paid to third party consulting firms for services provided to improve training and communication with active sites in support of our Phase III Levo-CTS clinical trial and to conduct market research for sepsis and cardiac surgery.

Personnel costs:

Personnel costs increased approximately $69,000 for the eight months ended December 31, 2015 compared to the same period in the prior year, primarily due to approximately $75,000 for annual bonuses accrued, partially offset by reduced costs for benefits and payroll taxes paid due to the headcount reductions in positions responsible for the development of our Oxycyte products as compared to the same period in the prior year.

Other costs:

Other costs decreased approximately $20,000 for the eight months ended December 31, 2015 compared to the same period in the prior year. This decrease was due primarily to depreciation of lab equipment and other lab related costs that were written off and disposed of on April 30, 2015.

Interest expense

Interest expense includes the interest payments due under our long-term debt, amortization of debt issuance costs and accretion of discounts recorded against our outstanding convertible notes and noncash interest charges related to our Series A Stock, when it was outstanding. Interest expense and percentage changes for the eight months ended December 31, 2015 and 2014, respectively, are as follows:

	Eight months ended December 31,				Increase/ (Decrease)			% Increase/ (Decrease)
	2015		2014
Interest expense	$	1,507	$	46,736	$	(45,229	)		(97	) %

During the eight months ended December 31, 2015, interest expense decreased approximately $45,000 compared to the same period in the prior year. The decrease was due primarily to the maturity and settlement of our outstanding convertible notes in June 2014.

Other income and expense

Other income and expense includes non-operating income and expense items not otherwise recorded in our consolidated statement of operations. These items include, but are not limited to, revenue earned under sublease agreements for our California facility, changes in the fair value of financial assets and liabilities, interest income earned and fixed asset disposals. Other income for the eight months ended December 31, 2015 and 2014, respectively, is as follows:

	Eight months ended December 31,						(Increase)/ Decrease
	2015			2014
Other (income) expense, net	$	(359,041	)	$	(509,420	)	$	150,379

Other income decreased approximately $150,000 for the eight months ended December 31, 2015 compared to the same period in the prior year. This decrease was primarily due to changes in the recognized fair value of our derivative warrant liability during the current period, partially offset by an increase of approximately $71,000 in interest income earned, net of amortization of premiums and market adjustments.

Gross profit	$	-	$	(104,069	)	$	104,069			(100	) %

The decrease in product revenue for the year ended April 30, 2015 was due to our decision to stop producing and selling the Dermacyte product in the year ended April 30, 2014.

28

Gross profit as a percentage of revenue was (404) % for the year ended April 30, 2014.  There was no gross profit during the year ended April 30, 2015 due to the write down of Dermacyte product in the prior year that is no longer being marketed for sale.

Government Grant Revenue

Revenues from a cost-reimbursement grant sponsored by the United States Army, or Grant Revenue, are recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.

	Year ended April 30,				Increase/ (Decrease)			% Increase/ (Decrease)
	2015		2014
Government grant revenue	$	49,286	$	262,995	$	(213,709	)		(81	) %

For the year ended April 30, 2015, we recorded approximately $49,000 in revenue under the grant program as compared to approximately $263,000 in revenue during the prior year. The decrease in revenue earned under the grant is due primarily to our completion of multiple studies in the prior year.

Depreciation and amortization		114,848		115,042		(194	)		(0	) %

Legal and professional fees:

Legal and professional fees increased approximately $460,000 for the year ended April 30, 2015 compared to the year ended April 30, 2014. This increase was primarily due to costs incurred for investor relations services, consulting fees and Board of Directors fees, partially offset by a decrease in legal fees.

-   Costs associated with investor relations and communication increased approximately $636,000 in the year ended April 30, 2015. This increase was due primarily to the issuance of 175,000 warrants with a calculated fair value of approximately $475,000 and an increase of approximately $161,000 in fees paid to outsourced corporate communication firms for investor relations services and website development.

-   Board of Directors fees increased in the year ended April 30, 2015 by approximately $420,000. This increase was due primarily to approximately $280,000 in recognized expense for the vesting of stock options awarded and an increase of approximately $140,000 in fees paid due to the addition of a director and the restructuring of directors’ fees in the year ended April 30, 2015.

-   Consulting costs increased approximately $132,000 in the year ended April 30, 2015 due primarily to fees paid for recruiting firms for placement services and contract labor in the year ended April 30, 2015.

-   Legal, accounting and capital market fees decreased in the year ended April 30, 2015 by approximately $600,000. This decrease was due primarily to a reduction of approximately $530,000 in accounting and legal fees incurred in the year ended April 30, 2014 related to the acquisition of the rights to develop levosimendan and the issuance of our Series C and Series D Preferred Stock and a reduction of approximately $70,000 in fees paid for the listing of additional shares with Nasdaq and SEC filings made during the year ended April 30, 2014.

29

Personnel costs:

Personnel costs decreased approximately $7.6 million for the year ended April 30, 2015 compared to the prior year. The decrease was due primarily to the recognition of approximately $8.3 million of stock based compensation in the year ended April 30, 2014, partially offset by an increase of approximately $633,000 in salaries and benefits paid during the year ended April 30, 2015.

-   Stock based compensation and the vested value of issued stock options decreased approximately $8.3 million in the year ended April 30, 2015 due primarily to the expense recognition of approximately $8.3 million for the granting and vesting of stock options and restricted stock in the year ended April 30, 2014. These option grants were made pursuant to employment agreements, which were negotiated in connection with our acquisition of a license for levosimendan in November 2013.

-   Salaries and benefits increased approximately $633,000 in the year ended April 30, 2015. This increase was due primarily to full-year salaries paid in the year ended April 30, 2015 to our Chief Executive Officer and the two additional management positions added in connection with our acquisition of certain assets of Phyxius, and approximately $210,000 for severance payments related to the stoppage of Oxycyte development programs.

Other costs:

The approximately $540,000 increase in other costs was due primarily to an increase of approximately $320,000 in franchise tax payments made to North Carolina and Delaware in the year ended April 30, 2015, an increase of approximately $100,000 in banking fees paid to manage our investment portfolio, an increase of approximately $45,000 in travel related costs, an increase of approximately $45,000 in insurance costs related to our Phase III clinical study, and approximately $30,000 in relocation costs paid in the year ended April 30, 2015.

Facilities		4,439		10,263		(5,824	)		(57	) %

Clinical and preclinical development:

The increase of approximately $4.1 million in clinical and preclinical development costs for the year ended April 30, 2015 compared to the year ended April 30, 2014 was primarily due to increased expenditures related to levosimendan and additional costs related to the decision to suspend the development of Oxycyte.

30

Levosimendan

We incurred approximately $4.5 million in research and development costs for levosimendan in the year ended April 30, 2015, an increase of approximately $4.3 million compared to the year ended April 30, 2014. The increase in levosimendan development costs is due primarily to the direct costs of our Phase III Levo-CTS clinical trial for LCOS. In the year ended April 30, 2015, we recorded clinical trial costs of approximately $4.0 million for the management of the Phase III trial and pass-through site activation and enrolled patient costs. In addition to the costs associated with the Phase III trial, we incurred expenses of approximately $516,000 to support the development of levosimendan for septic shock by providing financial support for the LeoPaRDS trial, which is currently being conducted through the Imperial College of London.

Oxycyte

We incurred approximately $1.5 million in research and development costs for Oxycyte in the year ended April 30, 2015, a decrease of approximately $248,000 compared to year ended April 30, 2014. The decrease in Oxycyte development costs was due primarily to our decision to suspend development of the Oxycyte product in the year ended April 30, 2015 and close out all of our sites for the Phase II-B clinical trial for TBI. We recorded costs of approximately $837,000 for these close-out activities and we do not anticipate any significant additional costs in the future related to this clinical trial.

We incurred approximately $98,000 in preclinical research and development costs, a decrease of approximately $147,000 compared to the year ended April 30, 2014. The decrease in preclinical development costs was due primarily to the completion and preparation of the final study reports for the Army funded safety studies and we do not anticipate any significant additional costs in the future related to these preclinical studies.

We incurred approximately $550,000 in manufacturing and stability costs for Oxycyte in the year ended April 30, 2015. These costs were due primarily to early termination fees for API and clinical drug manufacturing supply agreements due to our decision to suspend the development of Oxycyte, and we do not anticipate any significant additional costs in the future related to the manufacture and stability of Oxycyte.

Personnel costs:

Personnel costs decreased approximately $293,000 for the year ended April 30, 2015 compared to the year ended April 30, 2014 primarily due to headcount reductions in the year ended April 30, 2015, partially offset by the addition of our Chief Medical Officer in the fourth quarter of the year ended April 30, 2015. The headcount reductions were primarily in positions responsible for managing the manufacturing of Oxycyte clinical drug material, the preclinical safety studies for Oxycyte and the Phase II-B clinical trial for TBI.

Consulting fees:

Consulting fees decreased approximately $118,000 for the year ended April 30, 2015 compared to the year ended April 30, 2014 primarily due to approximately $142,000 of fees incurred to plan and prepare for clinical trial expansions and other clinical support activities for Oxycyte in the year ended April 30, 2014, partially offset by an increase of approximately $24,000 of consulting fees associated with levosimendan development in the year ended April 30, 2015.

Depreciation:

Depreciation expense remained relatively consistent for the years ended April 30, 2015 and 2014.

The increase was due primarily to the expense recognition of approximately $8.3 million for the granting and vesting of stock options and restricted stock, an increase of approximately $350,000 in salaries paid due to the addition of our new Chief Executive Officer and two other management positions and approximately $550,000 in performance bonuses paid and accrued for in the year ended April 30, 2014 that were not paid in the year ended April 30, 2013. The personnel costs attributable to Mr. Kelley, Mr. Jebsen, Mr. Randall and Dr. Hay reflect option grants made pursuant to their respective employment agreements, which were negotiated in connection with our acquisition of a license for levosimendan. In addition, Mr. Jebsen was paid a discretionary bonus consisting of $225,000 in cash and 32,143 shares of restricted common stock in recognition of his service as interim Chief Executive Officer from August 2011 through November 2013.

33

Legal and professional fees:

Legal and professional fees increased approximately $550,000 for the year ended April 30, 2014 compared to the year ended April 30, 2013. This increase was primarily due to costs incurred for investor relations services and audit fees, partially offset by a decrease in legal and recruiting fees.

-   Audit and accounting fees increased approximately $55,000 due to the costs incurred for valuation services related to the Phyxius acquisition and the filing of registration statements in the year ended April 30, 2014.

-   Investor relation fees increased approximately $560,000 for the costs of outsourced corporate communications firms, road shows and attending investor conferences.

-   Legal fees decreased approximately $40,000 due primarily to approximately $285,000 in fees incurred in the year ended April 30, 2013 for litigation defense costs, partially offset by an increase of approximately $245,000 in fees related to the Phyxius acquisition and the filing of registration statements in the year ended April 30, 2014.

-   Recruiting fees decreased approximately $25,000 due to headcount additions in the year ended April 30, 2013.

Other costs:

The approximately $558,000 increase in other costs was due primarily to the reversal of a contingent liability in the year ended April 30, 2013 related to potential liabilities in connection with non-compliance with Section 409A of the Internal Revenue Code.

Other expense increased approximately $730,000 for the year ended April 30, 2014 compared to the year ended April 30, 2013 primarily due to the change in the recognized fair value of our warrant liability in the year ended April 30, 2014.

Liquidity, capital resources and plan of operation

We have incurred losses since our inception and as of December 31, 2015 we had an accumulated deficit of approximately $161 million. We will continue to incur losses until we generate sufficient revenue to offset our expenses, and we anticipate that we will continue to incur net losses for at least the next several years. We expect to incur increased expenses related to our development and potential commercialization of levosimendan for LCOS and other product candidates, and, as a result, we will need to generate significant net product sales, royalty and other revenues to achieve profitability.

Liquidity

We have financed our operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. We had total current assets of $20,560,353 and $17,511,176 and working capital of $15,958,723 and $12,993,966 as of December 31, 2015 and April 30, 2015, respectively. Our practice is to invest excess cash, where available, in short-term money market investment instruments and high quality corporate and government bonds.

Clinical and Preclinical Product Development

We are in the clinical trial stage in the development of our product candidates. We are currently conducting a Phase III clinical trial for levosimendan. We expect our primary focus will be on completing the Phase III clinical trials for levosimendan. Our ability to continue to pursue testing and development of our products beyond the calendar year 2017 may depend on obtaining license income or outside financial resources. There is no assurance that we will obtain any license agreement or outside financing or that we will otherwise succeed in obtaining any necessary resources.

During the years ended April 30, 2015 and 2014, we received approximately $544,000 and $7.1 million and issued 209,230 and 3,161,145 shares of common stock, respectively upon the exercise of our outstanding warrants.  We did not complete any financings during the eight months ended December 31, 2015.

On March 21, 2014, we sold 9,285,714 shares of common stock for net proceeds of approximately $55 million.

On July 23, 2013, we sold 5,369 shares of Series C 8% convertible preferred stock and warrants for net proceeds of approximately $4.9 million. Additionally, on August 22, 2013 we issued 4,600 shares of Series D convertible preferred stock and warrants in exchange for $4.6 million of convertible notes that were scheduled to mature in June 2014.

Cash Flows

The following table shows a summary of our cash flows for the periods indicated:

	Eight months ended December 31,
	2015			2014
Net cash used in operating activities	$	(8,950,610	)	$	(6,632,268	)
Net cash used in investing activities		4,784,732			(40,356,616	)
Net cash provided by financing activities		(100,160	)		344,654

Net cash used in operating activities.  Net cash used in operating activities was $8.95 million for the eight months ended December 31, 2015 compared to net cash used in operating activities of $6.6 million for the eight months ended December 31, 2014. The increase in cash used for operating activities of $3.3 million was due primarily to cost incurred for the Phase III clinic trials for LCOS, partially offset by a decrease in legal and professional fees paid.

Net cash used in investing activities. Net cash provided by investing activities was $4.8 million for the eight months ended December 31, 2015 compared to net cash used in investing activities of $40.4 million for the eight months ended December 31, 2014. The increase in cash provided by investing activities was due primarily to the sales of marketable securities that were purchased during the prior period.

Net cash provided by financing activities. Net cash used in financing activities was $100,160 for the eight months ended December 31, 2015 compared to net cash provided by financing activities of $344,654 for the eight months ended December 31, 2014. The increase in net cash used in financing activities was due primarily to proceeds received from the exercise of warrants in the prior period.

	Year ended April 30,
	2015			2014
Net cash used in operating activities	$	(9,748,794	)	$	(9,261,571	)
Net cash provided by (used in) investing activities		(40,925,860	)		(147,038	)
Net cash (used in) provided by financing activities		280,590			66,945,636

Net cash used in operating activities. Net cash used in operating activities was $9.75 million for the year ended April 30, 2015 compared to net cash used in operating activities of $9.26 million for the year ended April 30, 2014. The increase in cash used for operating activities was due primarily to an increase in our costs incurred for the Phase III clinical trials for LCOS and an increase in personnel costs, partially offset by the payment of approximately $1.25 million in assumed liabilities during the prior year.

Net cash used in investing activities. Net cash used in investing activities was $40.93 million for the year ended April 30, 2015 compared to net cash used in investing activities of $147,038 for the year ended April 30, 2014. The increase in cash used for investing activities was due primarily to our investment in marketable securities throughout the year.

Net cash provided by financing activities. Net cash provided by financing activities was $280,590 for the year ended April 30, 2015 compared to net cash provided by financing activities of $66.9 million for the year ended April 30, 2014. The decrease of net cash provided by financing activities was due primarily to net proceeds of $55 million received from the issuance of common stock, $4.9 million received from the issuance of Series C 8% Convertible Preferred Stock and proceeds of $7 million received from the exercise of certain warrants in the prior year.

	Year ended April 30,
	2014			2013
Net cash used in operating activities	$	(9,261,571	)	$	(4,921,283	)
Net cash provided by (used in) investing activities		(147,038	)		(147,987	)
Net cash (used in) provided by financing activities		66,945,636			3,972,926

37

Net cash used in operating activities.  Net cash used in operating activities was $9.26 million for the year ended April 30, 2014 compared to net cash used in operating activities of $4.92 million for the year ended April 30, 2013. The increase in cash used for operating activities was due primarily to an increase in our costs incurred for the Phase II-b TBI clinical trials, the costs incurred to initiate the Phase III clinical trials for LCOS, the payment of approximately $1.25 million in assumed liabilities during the year, the increase in personnel costs, and the costs associated with the Phyxius asset acquisition.

Net cash used in investing activities. Net cash used in investing activities was $147,038 for the year ended April 30, 2014 compared to net cash used in investing activities of $147,987 for the year ended April 30, 2013. The cash used for investing activities, primarily capitalized legal fees incurred for filing and maintaining our patent portfolio, remained relatively consistent compared to the same period in the prior year.

Net cash provided by financing activities. Net cash provided by financing activities was $66.9 million for the year ended April 30, 2014 compared to net cash provided by financing activities of $4.0 million for the year ended April 30, 2013. The increase of net cash provided by financing activities was due primarily to net proceeds of $55 million received from the issuance of common stock on March 21, 2014, $4.9 million received from the issuance of Series C 8% Convertible Preferred Stock on July 23, 2013 and proceeds of $7 million received from the exercise of certain warrants as compared to the $2.5 million received from the issuance Series A Preferred Stock and $1.9 million received from the issuance of Series B Preferred Stock in the prior year.

Operating Capital and Capital Expenditure Requirements

Our future capital requirements will depend on many factors that include, but are not limited to the following:

- The initiation, progress, timing and completion of clinical trials for our product candidates and potential product candidates;

- The outcome, timing and cost of regulatory approvals and the regulatory approval process;

- Delays that may be caused by changing regulatory requirements;

- The number of product candidates that we pursue;

- The costs involved in filing and prosecuting patent applications and enforcing and defending patent claims;

- The timing and terms of future in-licensing and out-licensing transactions;

- The cost and timing of establishing sales, marketing, manufacturing and distribution capabilities;

- The cost of procuring clinical and commercial supplies of our product candidates;

- The extent to which we acquire or invest in businesses, products or technologies; and

- The possible costs of litigation.

Based on our working capital at December 31, 2015 we believe we have sufficient capital on hand to continue to fund operations through the calendar year 2017.

We will need substantial additional capital in the future in order to complete the commercialization of levosimendan, as well as 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.

To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital.

38

Contractual Obligations

Contractual obligations represent future cash commitments and liabilities under agreements with third parties and exclude contingent contractual liabilities for which we cannot reasonably predict future payment, including contingencies related to potential future development, financing, contingent royalty payments and/or scientific, regulatory or commercial milestone payments under development agreements. The following table summarizes our contractual obligations as of December 31, 2015:

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, including the use of structured finance, special purpose entities or variable interest entities.

Summary of Critical Accounting Policies

Use of Estimates—The preparation of the accompanying Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Preclinical Study and Clinical Accruals—We estimate our preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and CROs that conduct and manage preclinical and clinical trials on our behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:

- Fees paid to CROs in connection with clinical trials,

- Fees paid to research institutions in conjunction with preclinical research studies, and

- Fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.

Revenue Recognition—Revenues from merchandise sales are recognized upon transfer of ownership, including passage of title to the customer and transfer of the risk of loss related to those goods.  Revenues are reported on a net sales basis, which is computed by deducting from gross sales the amount of actual product returns received, discounts, incentive arrangements with retailers and an amount established for anticipated product returns.

Grant Revenue is recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.

Stock-Based Compensation—We account for stock-based awards to employees in accordance with Accounting Standards Codification, or ASC, 718 Compensation — Stock Compensation, which provides for the use of the fair value based method to determine compensation for all arrangements where shares of stock or equity instruments are issued for compensation. Fair values of equity securities are determined by management based predominantly on the trading price of our common stock. The values of these awards are based upon their grant-date fair value. That cost is recognized over the period during which the employee is required to provide service in exchange for the reward.

39

We account for equity instruments issued to non-employees in accordance with ASC 505-50 Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest.

Impairment Testing—In accordance with GAAP, goodwill impairment testing is performed at the reporting unit level annually, or more frequently if indicated by events or conditions. We performed an evaluation and determined that there is only one reporting unit. In the course of the evaluation of the potential impairment of goodwill, either a qualitative or a quantitative assessment may be performed. If a qualitative evaluation determines that no impairment exists, then no further analysis is performed. If a qualitative evaluation is unable to determine whether impairment has occurred, a quantitative evaluation is performed. The quantitative impairment test first identifies potential impairments by comparing the fair value of the reporting unit with its carrying value. If the fair value exceeds the carrying amount, goodwill is not impaired. If the carrying value exceeds the fair value, the implied fair value of goodwill is calculated and an impairment is recorded if the implied fair value is less than the carrying amount. The determination of goodwill impairment is highly subjective. It considers many factors both internal and external and is subject to significant changes from period to period. No goodwill impairment charges have resulted from this analysis for the eight months ended December 31, 2015, or the years ended April 30, 2015 and 2014.

Fair market value accounting (derivative warrant liability)—The most significant estimate that could have a material effect on net (loss) gain is the fair market value accounting for our derivative liability. Our derivative liability consists of free standing warrants that are recorded as liabilities due to the price protection anti-dilution provisions in the event of a subsequent equity sale. As a result, the warrants must be recorded as a liability at fair value. The changes in fair value are posted in other (income) expense. We utilize the Monte Carlo method to estimate the fair value of our warrants. The three most significant factors in the Monte Carlo method are (i) our stock price, (ii) the volatility of our stock price and (iii) the remaining term of the warrants. During the eight months  ending December 31, 2015, a $0.14 decrease in the value of our stock was the primary cause of the $48,105 derivative gain.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board, or FASB, issued a new accounting standard intended to improve financial reporting about leasing transactions. The new standard will require us to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leased assets. The new standard will also require us to provide enhanced disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from all leases, operating and capital, with lease terms greater than 12 month. The new standard is effective for financial statements beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted. See Note I for our current lease commitments. We are currently evaluating the impact that this new standard will have on our financial statements and related disclosures.

In January 2016, the FASB issued a new accounting standard that will enhance our reporting for financial instruments. The new standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier adoption is permitted for interim and annual reporting periods as of the beginning of the fiscal year of adoption. We do not believe the adoption of this standard will have a material impact on our consolidated financial statements.

In November 2015, the FASB issued a new accounting standard that changes the balance sheet classifications of deferred income taxes. This standard amends existing guidance to require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. It is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. We do not expect adoption of this standard will have a material impact on our consolidated financial statements.

In April 2015, the FASB issued a new accounting standard that will change the reporting of debt issuance costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. We do not expect adoption of this standard will have a material impact on our consolidated financial statements.

40

In August 2014, the FASB issued a new accounting standard that will require management to assess and evaluate whether conditions or events exist, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements issue date. It is effective for annual periods beginning after December 15, 2016 and for annual and interim periods thereafter; early adoption is permitted. We do not believe the adoption of this new standard to have a material effect on our consolidated financial statements.

In May 2014, the FASB issued a new accounting standard that supersedes nearly all existing revenue recognition guidance under GAAP. The new standard is principles-based and provides a five step model to determine when and how revenue is recognized. The core principle of the new standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. The new standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In July 2015, the FASB agreed to defer the effective date of the standard from annual periods beginning after December 15, 2016, to annual periods beginning after December 15, 2017, with an option that permits companies to adopt the standard as early as the original effective date. Early application prior to the original effective date is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition method and we do not believe adoption of this standard will have a material impact on our consolidated financial statements and related disclosures.

ITEM 7A—QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We are subject to interest rate risk on our investment portfolio.

We invest in marketable securities in accordance with our investment policy. The primary objectives of our investment policy are to preserve capital, maintain proper liquidity to meet operating needs and maximize yields. Our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure to any single issue, issuer or type of investment. We place our excess cash with high credit quality financial institutions, commercial companies, and government agencies in order to limit the amount of credit exposure. Some of the securities we invest in may have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate.

Our investment exposure to market risk for changes in interest rates relates to the increase or decrease in the amount of interest income we can earn on our portfolio, changes in the market value due to changes in interest rates and other market factors as well as the increase or decrease in any realized gains and losses. Our investment portfolio includes only marketable securities and instruments with active secondary or resale markets to help ensure portfolio liquidity. A hypothetical 100 basis point drop in interest rates along the entire interest rate yield curve would not significantly affect the fair value of our interest sensitive financial instruments. We generally have the ability to hold our fixed-income investments to maturity and therefore do not expect that our operating results, financial position or cash flows will be materially impacted due to a sudden change in interest rates. However, our future investment income may fall short of expectations due to changes in interest rates, or we may suffer losses in principal if forced to sell securities which have declined in market value due to changes in interest rates or other factors, such as changes in credit risk related to the securities’ issuers. To minimize this risk, we schedule our investments to have maturities that coincide with our expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, we do not believe that we have material exposure to interest rate risk arising from our investments. Generally, our investments are not collateralized. We have not realized any significant losses from our investments.

We do not use interest rate derivative instruments to manage exposure to interest rate changes. We ensure the safety and preservation of invested principal funds by limiting default risk, market risk and reinvestment risk. We reduce default risk by investing in investment grade securities.

TENAX THERAPEUTICS, INC.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

Tenax Therapeutics, Inc.

Morrisville, North Carolina

We have audited the accompanying consolidated balance sheets of Tenax Therapeutics, Inc. and Subsidiary, formerly, Oxygen Biotherapeutics, Inc. (the “Company”) as of December 31, 2015 and April 30, 2015 and 2014, and the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the eight months ended December 31, 2015 and each of the years in the three-year period ended April 30, 2015. We also have audited the Company’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting included in Item 9A - Controls and Procedures in the Company’s December 31, 2015 Annual Report on Form 10-KT. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2015 and April 30, 2015 and 2014, and the results of its operations and its cash flows for the eight months ended December 31, 2015 and each of the years in the three-year period ended April 30, 2015, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

As discussed in Note B to the consolidated financial statements, the Company changed their fiscal year to a fiscal year beginning on January 1 and ending on December 31 of each year.

For the period ended December 31, 2015, the Company recognized a net loss of approximately $10.1 million and as of December 31, 2015, the Company had incurred cumulative net losses of approximately $160.7 million. Management’s plans with regard to liquidity and capital resources are described in Note B.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A—DESCRIPTION OF BUSINESS

Description of Business—Tenax Therapeutics (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 was 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. On September 19, 2014, the Company changed its name to Tenax Therapeutics, Inc.

On October 18, 2013, the Company created a wholly owned subsidiary, Life Newco, Inc., a Delaware corporation (“Life Newco”), to acquire certain assets of Phyxius Pharma, Inc., a Delaware corporation (“Phyxius”), pursuant to an Asset Purchase Agreement, dated October 21, 2013 (the “Asset Purchase Agreement”), by and among the Company, Life Newco, Phyxius and the stockholders of Phyxius (the “Phyxius Stockholders”).  As further discussed in Note D below, on November 13, 2013, under the terms and subject to the conditions of the Asset Purchase Agreement, Life Newco acquired certain assets, including a license granting Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada.

Reverse Stock Split

The Company initiated a 1-for-20 reverse stock split effective May 10, 2013. All shares and per share amounts in these Consolidated Financial Statements and notes thereto have been retroactively adjusted to give effect to the reverse stock split.

NOTE B—SUMMARY OF CRITICAL ACCOUNTING POLICIES

Use of Estimates

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

On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company’s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company’s results of operations and financial position could be materially impacted.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts and transactions of Tenax Therapeutics, Inc. and Life Newco, Inc. All material intercompany transactions and balances have been eliminated in consolidation.

Goodwill

Acquired businesses are accounted for using the acquisition method of accounting, which requires that assets acquired, including identifiable intangible assets, and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. If the acquired net assets do not constitute a business, the transaction is accounted for as an asset acquisition and no goodwill is recognized.

Goodwill is reviewed for impairment on an annual basis or more frequently if events or circumstances indicate potential impairment. The Company’s goodwill evaluation is based on both qualitative and quantitative assessments regarding the fair value of goodwill relative to its carrying value. The Company assesses qualitative factors to determine if its sole reporting unit’s fair value is more likely than not to exceed its carrying value, including goodwill. In the event the Company determines that it is more likely than not that its reporting unit’s fair value is less than its carrying amount, quantitative testing is performed comparing recorded values to estimated fair values. If the fair value exceeds the carrying value, goodwill is not impaired. If the carrying value exceeds the fair value, an impairment charge is recognized through a charge to operations based upon the excess of the carrying value of goodwill over the implied fair value.  There was no impairment to goodwill recognized during 2015 and 2014.

49

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.

Cash Concentration Risk

On July 21, 2010, the Wall Street Reform and Consumer Protection Act permanently increased the Federal Deposit Insurance Corporation (the “FDIC”) insurance limits to $250,000 per depositor per insured bank. The Company had cash balances of $7,190,971 and $58,038,597 uninsured by the FDIC as of April 30, 2015 and 2014, respectively.

At December 31, 2015, the Company had $2,908,446 of cash balances uninsured by the FDIC.

Liquidity and Capital Resources

The Company has financed its operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. The Company had total current assets of $20,560,353; $17,511,176 and $58,966,033 and working capital of $15,958,723; $12,993,966 and $56,394,986 as of December 31, 2015, April 30, 2015 and April 30, 2014, respectively.

Cash resources, including the fair value of the Company’s available for sale marketable securities as of December 31, 2015 were approximately $38.2 million, compared to approximately $48.1 million as of April 30, 2015, and approximately $58.3 million as of April 30, 2014.

Based on its resources at December 31, 2015, and the current plan of expenditure on continuing development of the Company’s current product candidates, the Company believes that it has sufficient capital to fund its operations through the calendar year 2017. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot assure that it will be able to secure such additional financing, or if available, that it will be sufficient to meet its needs.

To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates, or grant licenses on terms that may not be favorable to the Company. Any or all of the foregoing may have a material adverse effect on the Company’s business and financial performance.

Deferred financing costs

Deferred financing costs represent legal, due diligence and other direct costs incurred to raise capital or obtain debt. Direct costs include only “out-of-pocket” or incremental costs directly related to the effort, such as a finder’s fee and accounting and legal fees. These costs will be capitalized if the efforts are successful, or expensed when unsuccessful. Indirect costs are expensed as incurred. Deferred financing costs related to debt are amortized over the life of the debt. Deferred financing costs related to issuing equity are charged to Additional Paid-in Capital.

Derivative financial instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible promissory note instruments and other convertible equity instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under FASB ASC 815, Derivatives and Hedging (“ASC 815”) to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results.

50

Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments, and are evaluated and accounted for in accordance with the provisions of ASC 815.

Beneficial conversion and warrant valuation

In accordance with FASB ASC 470-20, Debt with Conversion and Other Options, the Company records a beneficial conversion feature (“BCF”) related to the issuance of convertible debt that have conversion features at fixed rates that are in-the-money when issued and the fair value of warrants issued in connection with those instruments. The BCF for the convertible instruments is recognized and measured by allocating a portion of the proceeds to warrants, based on their relative fair value, and as a reduction to the carrying amount of the convertible debt equal to the intrinsic value of the conversion feature. As described in Note F, the discount recorded in connection with the BCF and warrant valuation is recognized as non-cash interest expense and is amortized over the life of the convertible note.

Preclinical Study and Clinical Accruals

The Company estimates its preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and contract research organizations (“CROs”) that conduct and manage preclinical and clinical trials on its behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:

- Fees paid to CROs in connection with clinical trials,

- Fees paid to research institutions in conjunction with preclinical research studies, and

- Fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.

Property and Equipment, Net

Property and equipment are stated at cost, subject to adjustments for impairment, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the following estimated useful lives:

Laboratory equipment	3 – 5 years
Office equipment	5 years
Office furniture and fixtures	7 years
Computer equipment and software	3 years
Leasehold improvements	Shorter of useful life or remaining lease term

Maintenance and repairs are charged to expense as incurred, improvements to leased facilities and equipment are capitalized.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Revenue Recognition

Revenues from merchandise sales are recognized upon transfer of ownership, including passage of title to the customer and transfer of the risk of loss related to those goods.  Revenues are reported on a net sales basis, which is computed by deducting from gross sales the amount of actual product returns received, discounts, incentive arrangements with retailers and an amount established for anticipated product returns.  The Company’s practice is to accept product returns from retailers only if properly requested, authorized and approved.  As a percentage of gross sales, returns were less than 5% in fiscal years 2014 and 2013.

51

Revenues from a cost-reimbursement grant sponsored by the United States Army (“Grant Revenue”), are recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.

Research and Development Costs

Research and development costs include, but are not limited to, (i) expenses incurred under agreements with CROs and investigative sites, which conduct our clinical trials and a substantial portion of our preclinical studies; (ii) the cost of manufacturing and supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements, equipment, laboratory and other supplies.  All research and development expenses are expensed as incurred.

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.

Stock-Based Compensation

The Company accounts for stock based compensation in accordance with ASC 718 Compensation — Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based payment awards granted, modified and settled to our employees and directors. The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option on a straight-line basis over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.

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. Such amounts include shares potentially issuable under outstanding options, warrants and convertible debentures. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share follows.

Operating Leases

The Company maintains operating leases for its office and laboratory facilities. The lease agreements may include rent escalation clauses and tenant improvement allowances. The Company recognizes scheduled rent increases on a straight-line basis over the lease term beginning with the date the company takes possession of the leased space. Differences between rental expense and actual rental payments are recorded as deferred rent liabilities and are included in “Other liabilities” on the consolidated balance sheets.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board, or FASB, issued a new accounting standard intended to improve financial reporting about leasing transactions. The new standard will require the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leased assets. The new standard will also require it to provide enhanced disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from all leases, operating and capital, with lease terms greater than 12 month. The new standard is effective for financial statements beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted. See Note I for its current lease commitments. The Company is currently evaluating the impact that this new standard will have on our financial statements and related disclosures.

In January 2016, the FASB issued a new accounting standard that will enhance the Company’s reporting for financial instruments. The new standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier adoption is permitted for interim and annual reporting periods as of the beginning of the fiscal year of adoption. The Company does not believe the adoption of this standard will have a material impact on its consolidated financial statements.

In November 2015, the FASB issued a new accounting standard that changes the balance sheet classifications of deferred income taxes. This standard amends existing guidance to require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. It is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company does not expect adoption of this standard will have a material impact on its consolidated financial statements.

In April 2015, the FASB issued a new accounting standard that will change the reporting of debt issuance costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect adoption of this standard will have a material impact on its consolidated financial statements.

In August 2014, the FASB issued a new accounting standard that will require management to assess and evaluate whether conditions or events exist, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements issue date. It is effective for annual periods beginning after December 15, 2016 and for annual and interim periods thereafter; early adoption is permitted. The Company does not believe the adoption of this new standard to have a material effect on its consolidated financial statements.

In May 2014, the FASB issued a new accounting standard that supersedes nearly all existing revenue recognition guidance under GAAP. The new standard is principles-based and provides a five step model to determine when and how revenue is recognized. The core principle of the new standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. The new standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In July 2015, the FASB agreed to defer the effective date of the standard from annual periods beginning after December 15, 2016, to annual periods beginning after December 15, 2017, with an option that permits companies to adopt the standard as early as the original effective date. Early application prior to the original effective date is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and it does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.

Fair Value

The Company determines the fair value of its financial assets and liabilities in accordance with the FASB Accounting Standards Codification (“ASC”) 820 Fair Value Measurements. The Company’s balance sheet includes the following financial instruments: cash and cash equivalents, investments in marketable securities, short-term notes payable, and warrant liabilities. 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.

Accounting for fair value measurements involves a single definition of fair value, along with a conceptual framework to measure fair value, with a fair value defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The fair value measurement hierarchy consists of three levels:

Level one	Quoted market prices in active markets for identical assets or liabilities;
Level two	Inputs other than level one inputs that are either directly or indirectly observable; and
Level three	Unobservable inputs developed using estimates and assumptions; which are developed by the reporting entity and reflect those assumptions that a market participant would use.

The Company applies valuation techniques that (1) place greater reliance on observable inputs and less reliance on unobservable inputs and (2) are consistent with the market approach, the income approach and/or the cost approach, and include enhanced disclosures of fair value measurements in the Company’s consolidated financial statements.

Investments in Marketable Securities

The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive income/(loss), unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in other income (expense) in the Consolidated Statements of Operations and Comprehensive Loss and are determined using the specific identification method with transactions recorded on a settlement date basis.

The Company recognized a loss of $43,871 for the eight months ended December 31, 2015. For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $1,025, $0 and $0, respectively.

Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At December 31, 2015, the Company believes that the costs of its investments are recoverable in all material respects.

54

The following tables summarize the fair value of the Company’s investments by type. The estimated fair value of the Company’s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These fair values are obtained from independent pricing services which utilize Level 2 inputs:

	December 31, 2015
	Amortized Cost		Accrued Interest		Gross Unrealized Gains		Gross Unrealized Losses			Estimated Fair Value
Corporate debt securities	$	34,391,859	$	285,132	$	3,158	$	(132,601	)	$	34,547,548

The following table summarizes the scheduled maturity for the Company’s investments at December 31, 2015, April 30, 2015 and 2014, respectively:

	December 31, 2015		April 30, 2015		April 30, 2014
Maturing in one year or less	$	16,528,494	$	9,200,082	$	-

Total investments	$	34,547,548	$	40,175,043	$	-

Warrant liability

On July 23, 2013, the Company issued common stock warrants in connection with the issuance of Series C 8% Preferred Stock (the “Series C Warrants”). As part of the offering, the Company issued 2,753,348 warrants at an exercise price of $2.60 per share and contractual term of 6 years. On November 11, 2013, the Company satisfied certain contractual obligations pursuant to the Series C offering which caused certain “down-round” price protection clauses in the outstanding warrants to become effective on that date. In accordance with ASC 815-40-35-9, the Company reclassified these warrants as a current liability and recorded a warrant liability of $1,380,883, which represents the fair market value of the warrants at that date. The initial fair value recorded as warrants within stockholders’ equity of $233,036 was reversed and the subsequent changes in fair value are recorded as a component of other expense.

Financial assets or liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. The Series C Warrants are measured using the Monte Carlo valuation model which is based, in part, upon inputs for which there is little or no observable market data, requiring the Company to develop its own assumptions.  The assumptions used in calculating the estimated fair value of the warrants represent the Company’s best estimates; however, these estimates involve inherent uncertainties and the application of management judgment.  As a result, if factors change and different assumptions are used, the warrant liabilities and the change in estimated fair value of the warrants could be materially different.

Inherent in the Monte Carlo valuation model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield.  The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.  The expected life of the warrants is assumed to be equivalent to their remaining contractual term.  The dividend rate is based on the historical rate, which the Company anticipates to remain at zero.

55

The Monte Carlo model is used for the Series C Warrants to appropriately value the potential future exercise price adjustments triggered by the anti-dilution provisions. This requires Level 3 inputs which are based on the Company’s estimates of the probability and timing of potential future financings and fundamental transactions.  The other assumptions used by the Company are summarized in the following table for the Series C Warrants that were outstanding as of December 31, 2015, April 30, 2015 and April 30, 2014:

Series C Warrants	December 31, 2015			April 30, 2015			April 30, 2014
Closing stock price	$	3.28		$	3.42		$	4.88
Expected dividend rate		0	%		0	%		0	%
Expected stock price volatility		84.08	%		83.53	%		90.32	%
Risk-free interest rate		1.44	%		1.23	%		1.75	%
Expected life (years)		3.56			4.23			5.23

As of December 31, 2015, the fair value of the warrant liability was $524,340. The Company recorded a gain of $48,105 for the change in fair value as a component of other expense on the condensed consolidated statement of comprehensive loss for the eight months ended December 31, 2015.

For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $382,431, a loss of $721,840 and $0, respectively, for the change in fair value as a component of other expense on the consolidated statement of operations.

A roll-forward of fair value measurements using significant unobservable inputs (Level 3) for the warrants for the eight months ended December 31, 2015 and the years ended April 30, 2015 and 2014 are as follows:

NOTE D—ACQUISITION

On November 13, 2013, the Company, through its wholly owned subsidiary, Life Newco, acquired certain assets of Phyxius pursuant to the Asset Purchase Agreement. The acquisition was accounted for under the acquisition method of accounting for business combinations in accordance with FASB ASC 805,  Business Combinations, which requires, among other things that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date.  Acquisition-related costs are not included as a component of the acquisition accounting, but are recognized as expenses in the periods in which the costs are incurred.  Any changes within the measurement period resulting from facts and circumstances that existed as of the acquisition date may result in retrospective adjustments to the provisional amounts recorded at the acquisition date.

Under the terms and subject to the conditions of the Asset Purchase Agreement, Life Newco acquired (the “Acquisition”) certain assets, including that certain License Agreement (the “License”), dated September 20, 2013 by and between Phyxius and Orion Corporation, a global healthcare company incorporated under the laws of Finland (“Orion”), and that certain Side Letter, dated October 15, 2013 by and between Phyxius and Orion.  The License grants Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial (the “Product”) in the United States and Canada (the “Territory”).  Pursuant to the License, Life Newco must use Orion’s “Simdax®” trademark to commercialize the Product.  The License also grants to Life Newco a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication.  Orion’s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the Territory, and certain regulatory participation rights.  Additionally, Life Newco must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by Life Newco under the License.  The License has a fifteen (15) year term, provided, however, that the License will continue after the end of the fifteen year term in each country in the Territory until the expiration of Orion’s patent rights in the Product in such country (the “Term”).  Orion had the right to terminate the License if the human clinical trial using the Product and studying reduction in morbidity and mortality of cardiac surgery patients at risk of low cardiac output syndrome (LCOS) as described in the US Food and Drug Administration (the “FDA”) agreed upon clinical study protocol (the “Study”) was not started by July 31, 2014. While the Company did not commence the trial by that date, on September 9, 2014, Orion notified the Company in writing that it did not intend to terminate the License so long as the trial was commenced on or before October 31, 2014.  The Company subsequently commenced the human clinical trial for levosimendan on September 18, 2014 when the first patient was enrolled.

The following table summarizes the consideration transferred to acquire Phyxius and the amounts of identified assets acquired and liabilities assumed at the acquisition date.

Fair Value of Consideration Transferred:

Common stock	8,747,802
Series E convertible preferred stock	15,299,198
Total	24,047,000

The Company issued 1,366,844 shares of its common stock that had a total fair value of approximately $8.7 million based on the closing market price on November 13, 2013, the acquisition date. The Company also issued 32,992 shares of its Series E Convertible Preferred Stock (the “Series E Stock”), which are convertible into an aggregate of 3,299,200 shares of common stock that had a total fair value of approximately $15.3 million.

The rights, preferences and privileges of the Series E Stock are set forth in the Certificate of Designation of Series E Convertible Preferred Stock that the Company filed with the Secretary of State of the State of Delaware on November 13, 2013.  Each share of Series E Stock automatically converted into 100 shares of common stock following receipt of stockholder approval for the transaction at the special meeting of stockholders held on March 13, 2014.  Approximately 11% of the shares of converted common stock vested immediately upon receipt of stockholder approval for the transaction, while the remainder vested upon the closing of the Company’s underwritten offering of 9,285,714 shares of common stock on March 21, 2014, which resulted in net proceeds of approximately $55 million.  

The Series E Stock was convertible into restricted common shares using a 100-for-one ratio at any time and in accordance with a vesting schedule contingent upon achievement of Company-specific non-financial conditions. As a result, the fair value of the Preferred Shares was inferred based on their common stock equivalent value given the conversion terms. The conditional vesting of the Series E Stock was accounted for by subtracting the fair value of an equal number of put options that would effectively protect the common stock equivalent stock value as of the closing date. The terms of the put options were as follows:

59

-   Exercise price equal to the common stock price as of the Valuation Date.

-   Term based on management’s risk-adjusted expected time to meeting the vesting condition, which was further increased by 6 months to reflect the marketability restriction of the unregistered stock, consistent with SEC Rule 144 of the Securities Act.

-   Volatility was consistent with the term for the individual milestone payments derived from the median historical asset volatility for a set of comparable guideline companies. The volatility was then relevered to estimate the equity volatility of the Company.

In accordance with the provisions of FASB ASC 805, the following table presents the preliminary allocation of the total fair value of consideration transferred, as discussed above, to the acquired tangible and intangible assets and assumed liabilities of Phyxius based on their estimated fair values as of the closing date of the transaction, measurement period adjustments recorded since the acquisition date and the adjusted allocation of the total fair value:

	November 13, 2013			Measurement			November 13, 2013
	(As initially reported)			Period Adjustments (1)			(As adjusted)
IPR&D	$	22,000,000		$	-		$	22,000,000
Trade and other payables		(256,000	)		-			(256,000	)
Liabilities arising from a contingency		(1,000,000	)		-			(1,000,000	)
Deferred tax liability related to intangibles acquired		-			(7,962,100	)		(7,962,100	)
Total identifiable net assets		20,744,000			(7,962,100	)		12,781,900
Goodwill		3,303,000			7,962,100			11,265,100
Total fair value of consideration	$	24,047,000		$	-		$	24,047,000

(1) The measurement period adjustments primarily reflect the recording of a deferred tax liability and resulting goodwill.  The measurement period adjustments were made to reflect facts and circumstances existing as of the acquisition date and did not result from intervening events subsequent to the acquisition date.

The fair value of the acquired in-process research and development, (“IPR&D”), intangible asset of approximately $22.0 million was determined using the multi-period excess earnings method. The Company did not acquire any other class of assets as a result of the acquisition.

Pursuant to the terms of the License, the Company paid to Orion a non-refundable up-front payment in the amount of $1 million.

The License also includes the following development milestones for which the Company shall make non-refundable payments to Orion no later than twenty-eight (28) days after the occurrence of the applicable milestone event: (i) $2.0 million upon the grant of FDA approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (ii) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the Territory. The Company must also pay Orion tiered royalties based on net sales of the Product in the Territory made by the Company and its sublicensees. After the end of the Term, the Company must pay Orion a royalty based on net sales of the Product in the Territory for as long as the Company sells the Product in the Territory.

In connection with the closing of the Acquisition, Phyxius’ co-founder, Chief Executive Officer and stockholder, John Kelley, became the Company’s Chief Executive Officer and two other Phyxius employees and stockholders, Doug Randall and Douglas Hay, PhD became employees of the Company as Vice President, Business and Commercial Operations and Vice President, Regulatory Affairs, respectively.  Michael Jebsen, the Company’s prior Interim Chief Executive Officer and current Chief Financial Officer, continued serving as the Company’s Chief Financial Officer.  In addition, Mr. Kelley was subsequently appointed to the Company’s Board of Directors, and Gerald T. Proehl, a designee of the Phyxius Stockholders, was appointed to the Board of Directors on April 3, 2014 following receipt of stockholder approval for the transaction.  Pursuant to the Asset Purchase Agreement, the Company agreed to propose that its stockholders approve an amendment to the Company’s 1999 Stock Plan to increase the amount of stock options authorized for issuance under the 1999 Stock Plan to not less than 4,000,000 shares of common stock. On March 13, 2014, the Company received stockholder approval to increase the option plan. In accordance with terms of the Acquisition, the Company issued an aggregate of 3,572,880 stock options with a grant date fair value of $15,818,512, to the individuals described above. See Note G for additional details.

60

The common stock and Series E Stock issued as the consideration in the Acquisition were issued and sold without registration under the Securities Act of 1933 (the “Securities Act”) in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws.  Accordingly, the Phyxius Stockholders may sell the shares of common stock and Series E Stock only pursuant to an effective registration statement under the Securities Act covering the resale of those securities, an exemption under Rule 144 under the Securities Act or another applicable exemption under the Securities Act.

For the fiscal years ended April 30, 2015, 2014, and 2013 the aggregate amortization expense on the above intangibles was $70,304, $62,189 and $55,845, respectively.

In Process Research and Development— The levosimendan product in Phase III clinical trial represents an IPR&D asset. The IPR&D asset is a research and development project rather than a product or processes already in service or being sold. Research and development intangible assets are considered indefinite-lived until the abandonment or completion of the associated research and development efforts. If abandoned, the assets would be impaired. Research and development expenditures that are incurred after the acquisition, including those for completing the research and development activities related to the acquired intangible research and development assets, are generally expensed as incurred.

Patents and License Rights—The Company currently holds, has filed for, or owns exclusive rights to, U.S. and worldwide patents covering 9 various methods and uses of its perfluorocarbon (“PFC”) technology. It capitalizes amounts paid to third parties for legal fees, application fees and other direct costs incurred in the filing and prosecution of its patent applications. These capitalized costs are amortized on a straight-line method over their useful life or legal life, whichever is shorter. For the fiscal years ended April 30, 2015, 2014, and 2013, the Company capitalized patent costs of approximately $105,000, $137,000 and $135,000, respectively.

The Company completed its annual impairment test of its patents and license rights during the fourth quarter of fiscal years 2015 and 2014. The Company wrote-off approximately $929,000 and $0 of capitalized costs for patent applications that were withdrawn or abandoned during the years ended April 30, 2015 and 2014, respectively. These asset impairment charges primarily related to the Company’s Oxycyte and other PFC formulations which were determined not to be a core component of the Company’s development strategy.

Trademarks—The Company currently holds, or has filed for, trademarks to protect the use of names and descriptions of its products and technology. It capitalizes amounts paid to third parties for legal fees, application fees and other direct costs incurred in the filing and prosecution of its trademark applications. These trademarks are evaluated annually for impairment in accordance with ASC 350, Intangibles – Goodwill and other. The Company evaluates (i) its expected use of the underlying asset, (ii) any laws, regulations, or contracts that may limit the useful life, (iii) the effects of obsolescence, demand, competition, and stability of the industry, and (iv) the level of costs to be incurred to commercialize the underlying asset. The Company wrote-off trademark costs of approximately $106,000 and $0, for the years ended April 30, 2015 and 2014, respectively. These asset impairment charges primarily related to the Company’s Oxycyte and other PFC formulations which were determined not to be a core component of the Company’s development strategy.

Convertible Note

On June 29, 2011, the Company issued a note (the “June Note”) with a principal amount of approximately $300,000 and Warrants to purchase 6,652 shares of common stock. On July 1, 2011, the Company issued a separate note (together with the June Note, the “Notes”) with a principal amount of $4,600,000 and warrants to purchase 101,996 shares of common stock. The aggregate gross proceeds to the Company from the offering were approximately $4.9 million, excluding any proceeds from the exercise of any warrants. The aggregate placement agent fees were $297,000 and legal fees associated with the offering were $88,839. These costs have been capitalized as debt issue costs and will be amortized as interest expense over the life of the Notes. The Company recorded amortization of debt issue costs of $21,427, $128,616 and $128,616 for the years ended April 30, 2015, 2014 and 2013, respectively. All debt issue costs were fully amortized in the first quarter of fiscal year ending April 30, 2015.

Interest on the Notes accrues at a rate of 15% annually and will be paid in quarterly installments commencing on the third month anniversary of issuance. The Notes were scheduled to mature 36 months from the date of issuance. The Notes may be converted into shares of common stock at a conversion price of $45.10 per share (subject to adjustment for stock splits, dividends and combinations, recapitalizations and the like) (the "Conversion Price") in whole or in part, at any time at the option of the holders of the Notes. The Notes also will automatically convert into shares of common stock at the Conversion Price at the election of a majority-in-interest of the holders of notes issued under the purchase agreement or upon the acquisition or sale of all or substantially all of the assets of the Company. The Company could make each applicable interest payment or payment of principal in cash, shares of common stock at the Conversion Price, or any combination thereof. The Company could elect to prepay all or any portion of the Notes without prepayment penalties only with the approval of a majority-in-interest of the note holders under the purchase agreement at the time of the election.   The Notes contained various events of default such as failing to timely make any payment under the Note when due, which would have resulted in all outstanding obligations under the Note becoming immediately due and payable.

On August 22, 2013 holders of $4.6 million of the Notes received 4,600 shares of the Company’s Series D 8% Convertible Preferred Stock (the “Series D Stock”) as consideration for cancelling their outstanding Notes. On that date, the Company recognized non-cash interest expense of $1,311,847 for the remaining unamortized debt discount associated with this Notes.

On June 29, 2014, the Company paid the remaining principal balance of $300,000 to the June Note holders upon maturity.

The Company recorded interest expense of $45,606, $2,181,955 and $2,507,156 for the years ended April 30, 2015, 2014 and 2013, respectively.

The total value allocated to the warrants was $1,960,497 and was recorded as a debt discount against the proceeds of the notes. In addition, the beneficial conversion features related to the Notes were determined to be $2,939,504.  As a result, the aggregate discount on the Notes totaled $4,900,001, and was amortized over the term of the notes. For the fiscal years ended April 30, 2015, 2014, and 2013, the Company recorded interest expense for the amortization of debt discount of $16,678, $483,330 and $1,633,332, respectively.

64

The table below sets forth a summary of the designation, powers, preferences and rights of the Series D Stock.

Conversion	Subject to certain ownership limitations, the Series D Stock is convertible at any time at the option of the holder into shares of the Company’s common stock at a conversion ratio determined by dividing the stated value of the Series C Stock (or $1,000) by a conversion price of $1.95 per share. The conversion price is subject to adjustment in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. Until such time that for at least 25 trading days during any 30 consecutive trading days, the volume weighted average price of the Company’s common stock exceeds 250% of the initial conversion price, if the Company sells or grants 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 then conversion price, or the Base Conversion Price, then the conversion price shall be reduced to equal the Base Conversion Price.
Dividends and Make-Whole Payment	Until the third anniversary of the date of issuance of the Series D Stock, the holder of the Series D Stock is entitled to receive dividends at the rate of 8% per annum of the stated value for each share of Series D Stock held by such holder payable quarterly on January 1, April 1, July 1 and October 1, beginning on the first such date after the original issue date, and on each dividend payment date.  The Company can elect to pay the dividends in cash or in duly authorized, validly issued, fully paid and non-assessable shares of common stock, or a combination thereof.  If the Company pays the dividends in shares of common stock, the shares used to pay the dividends will be valued at 90% of the average volume weighted average price for the 20 consecutive trading days ending on the trading day immediately prior to the applicable dividend payment date.  From and after the third anniversary of the date of issuance of the Series D Stock, the holder of Series D Stock will be entitled to receive dividends equal, on an as-if-converted to common stock basis, to and in the same form as dividends actually paid on shares of common stock when, as, and if such dividends are paid on shares of common stock.  The Company has never paid dividends on its common stock and the Company does not intend to do so for the foreseeable future. In the event OXBT Fund converts its Series D Stock prior to the third anniversary of the date of issuance of the Series D Stock, the Company must also pay to OXBT Fund in cash, or at the Company’s option in common stock valued as described above, or a combination of cash and shares of common stock, with respect to the Series D Stock so converted, an amount equal to $240 per $1,000 of the stated value of the Series D Stock, less the amount of any dividends paid in cash or in common stock on such Series D Stock on or before the date of conversion.
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 holder of Series D 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, 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.
Voting rights	Shares of Series D Stock will generally have no voting rights, except as required by law and except that the consent of the holder of the outstanding Series D Stock will, among other things, be required to amend the terms of the Series D Stock.

Until such time that for at least 25 trading days during any 30 consecutive trading days, the volume weighted average price of the Company’s common stock exceeds 250% of the initial conversion price, if the Company sells or grants 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 then conversion price, or the Base Conversion Price, then the conversion price shall be reduced to equal the Base Conversion Price.
Dividends and Make-Whole Payment	Until the third anniversary of the date of issuance of the Series C Stock, each holder of the Series C Stock is entitled to receive dividends at the rate of 8% per annum of the stated value for each share of Series C Stock held by such holder payable quarterly on January 1, April 1, July 1 and October 1, beginning on the first such date after the original issue date, and on each dividend payment date.  The Company can elect to pay the dividends in cash or in duly authorized, validly issued, fully paid and non-assessable shares of common stock, or a combination thereof.  If the Company pays the dividends in shares of common stock, the shares used to pay the dividends will be valued at 90% of the average volume weighted average price for the 20 consecutive trading days ending on the trading day immediately prior to the applicable dividend payment date.  From and after the third anniversary of the date of issuance of the Series C Stock, each holder of Series C Stock will be entitled to receive dividends equal, on an as-if-converted to common stock basis, to and in the same form as dividends actually paid on shares of common stock when, as, and if such dividends are paid on shares of common stock.  The Company has never paid dividends on its common stock and the Company does not intend to do so for the foreseeable future. In the event a holder converts his, her or its Series C Stock prior to the third anniversary of the date of issuance of the Series C Stock, the Company must also pay to the holder in cash, or at the Company’s option in common stock valued as described above, or a combination of cash and shares of common stock, with respect to the Series C Stock so converted, an amount equal to $240 per $1,000 of the stated value of the Series C Stock, less the amount of any dividends paid in cash or in common stock on such Series C Stock on or before the date of conversion.
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 C 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, 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.
Voting rights	Shares of Series C Stock will generally have no voting rights, except as required by law and except that the consent of holders of a majority of the outstanding Series C Stock will, among other things, be required to amend the terms of the Series C Stock.

Dividends	No dividends shall be paid on shares of Preferred Stock.
Conversion	Holders may elect to convert shares of Series B Stock into shares of common stock at the then-existing conversion price at any time.  The initial conversion price is $5.00 per share of common stock, and is subject to certain adjustments, including an anti-dilution provision that reduces the conversion price upon the issuance of any common stock or securities convertible into common stock at an effective price per share less than the conversion price and a one-time price reset following the effectiveness of a reverse split of the Company’s outstanding common stock.
Liquidation preference	In the event of the Company’s voluntary or involuntary dissolution, liquidation or winding up, each holder of Series B Stock will be entitled to be paid a liquidation preference equal to the initial stated value of such holder’s Series B Stock of $1,000 per share, plus accrued and unpaid dividends and any other payments that may be due on such shares, before any distribution of assets may be made to holders of capital stock ranking junior to the Series B Stock.

As part of the compensation under the agreement, the Company issued up to 175,000 warrants at an exercise price of $4.00 per share and contractual term of 5 years. The warrant is initially exercisable for 25,000 shares of common stock, and the number of shares of common stock exercisable under this warrant will be automatically increased by 50,000 upon the first occurrence of market price goals of $6.00, $8.00 and $10.00, respectively, during the eighteen month period beginning on the effective date. In accordance with ASC 815, these warrants are classified as equity and their estimated fair-value of $478,115 was recorded as an operating expense in the consolidated statement of operations and as additional paid in capital during the year ended April 30, 2015. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

Series D Warrants

On August 22, 2013, the Company closed its private placement of an aggregate of $4.6 million shares of the Company’s Series D Stock to OXBT Fund.  In connection with the purchase of shares of Series D Stock, OXBT Fund received the Series D Warrant to purchase 2,358,975 shares of common stock at an exercise price equal to $2.60 and contractual term of 6 years. In accordance with ASC 815, these warrants are classified as equity and their relative fair-value of $1,531,167 was recognized as a deemed dividend on the Series D Stock during the year ended April 30, 2014. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.  

The Series D Warrant is exercisable beginning on the date of issuance and expires on August 22, 2019.  The exercise price and the number of shares issuable upon exercise of Series D Warrant is subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company’s common stock, and also upon any distributions of assets, including cash, stock or other property to the Company’s stockholders.  In addition, if stockholder approval for the transaction is obtained, the Series D Warrant will be subject to anti-dilution provisions until such time that for 25 trading days during any 30 consecutive trading day period, the volume weighted average price of the Company’s common stock exceeds $6.50 and the daily dollar trading volume exceeds $350,000 per trading day.

68

On January 30, 2014, the Company entered into an agreement with the OXBT Fund to amend the terms of the outstanding Series D Warrants. The amendment replaced the price protection anti-dilution provision of each warrant with a covenant that the Company will not issue common stock or common stock equivalents at an effective price per share below the exercise price of such warrant without prior written consent, subject to certain exceptions.

The Series D Stock and the Series D Warrant were issued and sold without registration under the Securities Act in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws.  Accordingly, OXBT Fund may exercise the Warrant and sell the Series D Stock and underlying shares only pursuant to an effective registration statement under the Securities Act covering the resale of those securities, an exemption under Rule 144 under the Securities Act or another applicable exemption under the Securities Act.

During the year ended April 30, 2015, the Company received proceeds of $544,000 and issued 209,230 shares of common stock upon the exercise of the Series D warrants. As of December 31, 2015, 2,149,745 Series D Warrants are outstanding.

Series C Warrants

On July 23, 2013, as part of the offering of Series C Stock, the Company issued 2,753,348 Series C Warrants at an exercise price of $2.60 per share and contractual term of 6 years. In accordance with ASC 815, these warrants are classified as equity and their relative fair-value of $1,867,991 was recognized as a deemed dividend on the Series C Stock during the year ended April 30, 2014. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

In connection with the Series C Offering described above, the Company entered into a Placement Agency Agreement (the “Placement Agency Agreement”) with Ladenburg Thalmann & Co. Inc. (the “Placement Agent”) pursuant to which the Placement Agent agreed to act as the Company’s exclusive placement agent for the Series C Offering. In accordance with the Placement Agency Agreement, on July 23, 2013 the Company issued to the Placement Agent warrants to purchase 53,539 shares of common stock at an exercise price of $2.4375 per share and a contractual term of 3 years. In accordance with ASC 815, these warrants are classified as equity and their relative fair-value of $51,231 was recognized as additional paid in capital during the year ended April 30, 2014. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

During the year ended April 30, 2014, the Company received cash of approximately $6.5 million and issued 2,512,825 shares of common stock upon the exercise of outstanding Series C Warrants. As of December 31, 2015, 240,523 Series C Warrants are outstanding.

In accordance with ASC 815-40-35-8, the Company reassessed the classification of the remaining Series C Warrants. On November 11, 2013, the Company satisfied certain contractual obligations pursuant to the Series C offering which caused certain “down-round” price protection clauses in the outstanding warrants to become effective on that date. In accordance with ASC 815-40-35-9, on November 11, 2013, the Company reclassified these warrants as a current liability and recorded a warrant liability of $1,082,941 which represents the fair market value of the warrants at that date. The initial fair value recorded as warrants within stockholders’ equity of $233,036 was reversed and the change in fair value was recorded as a component of other expense.

The estimated fair value is determined using the Monte Carlo Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends, expected volatility of the price of the underlying common stock as well as other estimates and assumptions.

As of December 31, 2015, the fair value of the warrant liability was $524,340. The Company recorded a gain of $48,105 for the change in fair value as a component of other expense on the consolidated statement of operations and comprehensive loss for the eight months ended December 31, 2015.

For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $382,431, a loss of $721,840 and $0, respectively, for the change in fair value as a component of other expense on the consolidated statements of operations and comprehensive loss.

In connection with the issuance of 2,100 shares of Series B Preferred Stock described above, on February 27, 2013 the Company issued Class A and Class B warrants to purchase an aggregate of 630,000 shares of common stock. The warrants were issued at an initial exercise price equal to $10.00 and were immediately exercisable. The Class A warrants were issued with a six-year term and the Class B warrants were issued with a two-year term.

During the year ended April 30, 2014, the Company received proceeds of $567,000 and issued 630,000 shares of common stock upon the exercise of the Series B warrants. As of December 31, 2015, there were no Series B warrants outstanding.

1999 Amended Stock Plan

In October 2000, the Company adopted the 1999 Stock Plan, as amended and restated on June 17, 2008 (the “Plan”). Under the Plan, with the approval of the Compensation Committee of the Board of Directors, the Company may grant stock options, restricted stock, stock appreciation rights and new shares of common stock upon exercise of stock options. On September 30, 2011, the Company’s stockholders approved an amendment to the Plan which increased the amount of shares authorized for issuance under the Plan to 300,000, up from 40,000 previously authorized.

Pursuant to the Asset Purchase Agreement described in Note D above, the Company agreed to propose that its stockholders approve an amendment to the Company’s 1999 Stock Plan to increase the amount of stock options authorized for issuance under the 1999 Stock Plan to not less than 4,000,000 shares of common stock. On March 13, 2014, the Company’s stockholders approved an amendment to the Plan which increased the number of shares of common stock authorized for issuance to a total of 4,000,000 shares, up from 300,000 previously authorized.

During the year ended April 30, 2014, the Company recorded approximately $7.9 million of compensation expense for the vested options in its consolidated statements of operations. An additional $7.9 million of compensation expense related to these grants will be recognized as performance vesting conditions are achieved.

The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.

The Company used the following assumptions to estimate the fair value of options granted under its stock option plans for the eight months ended December 31, 2015 and the fiscal years ended April 30, 2015, 2014 and 2013:

	For the eight months ended December 31,			For the year ended April 30
	2015			2015			2014			2013
Risk-free interest rate (weighted average)		1.99	%		2.23	%		1.80	%		1.29	%
Expected volatility (weighted average)		85.45	%		98.43	%		98.20	%		79.62	%
Expected term (in years)		7			7			6			7
Expected dividend yield		0.00	%		0.00	%		0.00	%		0.00	%

Risk-Free Interest Rate	The risk-free interest rate assumption was based on U.S. Treasury instruments with a term that is consistent with the expected term of the Company’s stock options.
Expected Volatility	The expected stock price volatility for the Company’s common stock was determined by examining the historical volatility and trading history for its common stock over a term consistent with the expected term of its options.
Expected Term	The expected term of stock options represents the weighted average period the stock options are expected to remain outstanding. It was calculated based on the historical experience that the Company has had with its stock option grants.
Expected Dividend Yield	The expected dividend yield of 0% is based on the Company’s history and expectation of dividend payouts. The Company has not paid and do not anticipate paying any dividends in the near future.
Forfeitures	As stock-based compensation expense recognized in the statement of operations for the eight months ended December 31, 2015 and the fiscal years ended April 30, 2015, 2014 and 2013 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on the Company’s historical experience.

The weighted-average grant-date fair value of options granted during the eight months ended December 31, 2015 was $3.25.

The weighted-average grant-date fair value of options granted during the years ended April 30, 2015, 2014 and 2013 was $4.82, $5.64 and $32.60, respectively.

The Company recorded compensation expense for these stock options grants of $217,736 for the eight months ended December 31, 2015.

As of December 31, 2015, there were unrecognized compensation costs of approximately $587,000 related to non-vested stock option awards that will be recognized on a straight-line basis over the weighted average remaining vesting period of 1.6 year. Additionally, there were unrecognized compensation costs of approximately $7.9 million related to non-vested stock option awards subject to performance-based vesting milestones with a weighted average remaining life of 4.3 years. As of December 31, 2015, none of these milestones have been achieved.

Inducement Stock Options

The table below summarizes the employment inducement stock option award for 25,000 shares of common stock made to our chief medical officer on February 15, 2015. This employment inducement stock option was awarded in accordance with the employment inducement award exemption provided by NASDAQ Rule 5635(c)(4) and was therefore not awarded under the Company’s stockholder approved equity plan. The option award will vest over a three year period, with one-third vesting per year, beginning one year from the grant date. The options have a 10-year term and an exercise price of $3.22 per share, the February 13, 2015 closing price of the Company’s common stock.

Inducement stock option compensation expense was approximately $26,000 for the eight months ended December 31, 2015.

For the years ended April 30, 2015, 2014 and 2013 Inducement stock option compensation expense totaled $9,830, $0 and $0, respectively.

At December 31, 2015, there was $28,300 of remaining unrecognized compensation expense related to the inducement stock options. Inducement stock options outstanding as of December 31, 2015 had a weighted average remaining contractual life of 9.13 years.

The estimated weighted average fair value per inducement option share granted was $64,343 in 2015 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: weighted average risk-free interest rate of 1.84%, dividend yield of 0%, volatility factor for our common stock of 93.90% and a weighted average expected life of 7 years for inducement options not forfeited.

NOTE H—RESTRUCTURING EXPENSE

In May 2012, the Company decided to consolidate its operations and relocate its research and development function to North Carolina from Costa Mesa, California. To allow for this transition period, all existing development work had been completed and all of the manufacturing of the Company’s PFC-based products had been transferred to contract manufacturers. As part of these initiatives, the Company terminated all related research and development activities and a workforce reduction was implemented.  In September 2012, the Company entered into a sublease agreement with an unrelated third party that extends throughout the remaining term of the existing lease for the vacated facility.

The following table summarizes the impact of the work force reductions and other associated costs on operating expenses and payments for the eight months ended December 31, 2015, and the liability remaining on the balance sheet as of December 31, 2015.

Simdax license agreement

As further discussed in Note D above, on November 13, 2013 the Company acquired the License which granted it an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan in the United States and Canada.  Pursuant to the License, the Company must use Orion’s “Simdax®” trademark to commercialize the Product.  The License also grants to the Company a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication.  

Orion’s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the Territory, and certain regulatory participation rights.  Additionally, the Company must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by the Company under the License.  The License has a fifteen (15) year term, provided, however, that the License will continue after the end of the fifteen year term in each country in the Territory until the expiration of Orion’s patent rights in the Product in such country.  Orion had the right to terminate the License if the Study is not started by July 31, 2014.  While the Company did not commence the trial by that date, on September 9, 2014, Orion notified the Company in writing that it did not intend to terminate the License so long as the trial was commenced on or before October 31, 2014.  The Company subsequently commenced the human clinical trial for levosimendan on September 18, 2014 when the first patient was enrolled.

The License includes the following development milestones for which the Company shall make non-refundable payments to Orion no later than twenty-eight (28) days after the occurrence of the applicable milestone event: (i) $2.0 million upon the grant of FDA approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (ii) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the Territory.  The Company must also pay Orion tiered royalties based on net sales of the Product in the Territory made by the Company and its sublicensees. After the end of the Term, the Company must pay Orion a royalty based on net sales of the Product in the Territory for as long as Life Newco sells the Product in the Territory.

As of December 31, 2015, the Company has not met any of the developmental milestones and, accordingly, has not recorded any liability for the contingent payments due to Orion.

Agreement with Virginia Commonwealth University

In May 2008 the Company entered into a license agreement with Virginia Commonwealth University (“Licensor”, “VCU”) whereby it 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 unless the Company elects to terminate the agreement prior to patent expiration.  Under the agreement the Company has an obligation to diligently pursue product development and pursue, at its own expense, prosecution of the patent applications covered by the agreement. As part of the agreement, the Company is required to pay to VCU nonrefundable payments upon achieving development and regulatory milestones. As of April 30, 2015, the Company has not met any of the developmental milestones.

76

The agreement with VCU also requires the Company to pay royalties to VCU at specified rates based on annual net sales derived from the licensed technology. Pursuant to the agreement, the Company must make minimum annual royalty payments to VCU totaling $70,000 as long as the agreement is in force. These payments are fully creditable against royalty payments due for sales and sublicense revenue earned during the fiscal year as described above. This fee is recorded as an other current asset and is amortized over the fiscal year.  Amortization expense was $70,000 for each of the years ended April 30, 2015, 2014 and 2013.

In September 2014, the Company discontinued the development of its Oxycyte product candidates.  As part of the this change in business strategy, on May 5, 2015 the Company provided VCU its 90 day notice terminating the license agreement entered into with the Licensor, whose effective date was May 21, 2008.  The license agreement gave the Company exclusive rights to intellectual property that was used for the development and commercialization of Oxycyte and is therefore no longer needed.

Litigation

The Company is subject to litigation in the normal course of business, none of which management believes will have a material adverse effect on the Company’s Consolidated Financial Statements.

NOTE J—401(k) BENEFIT PLAN

The Company sponsors a 401(k) Retirement Savings Plan (the “401(k) Plan”) for all eligible employees. Full-time employees over the age of 18 are eligible to participate in the 401(k) Plan after 90 days of continuous employment. Participants may elect to defer earnings into the 401(k) Plan up to the annual IRS limits and the Company provides a matching contribution up to 5% of the participants’ annual salary in accordance with the 401(k) Plan documents. The 401(k) Plan is managed by a third-party trustee.

For the eight months ended December 31, 2015, the Company recorded $57,352 for matching contributions expense.

For the fiscal periods ended April 30, 2015, 2014 and 2013, the Company recorded $82,185, $47,087 and $46,847 respectively, for matching contributions expense.

NOTE K—INCOME TAXES

The Company has not recorded any income tax expense (benefit) for the periods ended December 31, 2015, April 30, 2015 and April 30, 2014 due to its history of net operating losses.

The reconciliation of income tax expenses (benefit) at the statutory federal income tax rate of 34% for the periods ended December 31, 2015, April 30, 2015 and April 30, 2014 is as follows:

	December 31,			April 30,
	2015			2015			2014
U.S. federal taxes (benefit) at statutory rate	$	(3,423,108	)	$	(4,787,816	)	$	(6,644,225	)

Other permanent differences		-			(140,532	)		292,355
Other, including expiration of NOL carryforwards		(72,808	)		425,567			53,621
Change in state tax rate		-			-			(8,377	)
Change in valuation allowance		3,868,081			5,049,445			3,145,098
	$	-		$	-		$	-

The tax effects of temporary differences and carry forwards that give rise to significant portions of the deferred tax assets are as follows:

	December 31,			April 30,
Deferred Tax Assets	2015			2015			2014
Net operating Loss Carryforwards	$	39,190,436		$	35,404,245		$	30,748,100
Accruals and other		691,341			618,400			230,900
Valuation allowance		(39,862,626	)		(35,994,545	)		(30,945,100	)
Net deferred tax assets		19,151			28,100			33,900
Deferred Tax Liabilities
IPR&D		(7,962,100	)		(7,962,100	)		(7,962,100	)
Other liabilities		(19,151	)		(28,100	)		(33,900	)
Net Deferred Tax Liabilities	$	(7,962,100	)	$	(7,962,100	)	$	(7,962,100	)

The Company has established a valuation allowance against net deferred tax assets due to the uncertainty that such assets will be realized. The Company periodically evaluates the recoverability of the deferred tax assets. At such time that it is determined that it is more likely than not that deferred tax assets will be realizable, the valuation allowance will be reduced.

As of December 31, 2015, the Company had Federal and State net operating loss carryforwards of approximately $105.3 million and $85.1 million available to offset future federal and state taxable income, respectively. The federal and state net operating loss carryforwards begin to expire in 2018 and valuation allowances have been provided.

Utilization of the net operating loss carryforwards may be subject to an annual limitation due to the ownership percentage change limitations provided by the Internal Revenue Code of 1986 and similar state provisions. The annual limitations may result in the expiration of the net operating losses before utilization.

Management has evaluated all other tax positions that could have a significant effect on the financial statements and determined the Company had no uncertain income tax positions at December 31, 2015.

The Company files U.S. and state income tax returns with varying statutes of limitations. The tax years 2001 and forward remain open to examination due to the carryover of unused net operating losses or tax credits.

ITEM 9A—CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in rules and forms adopted by the Securities and Exchange Commission, or SEC, and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures.

Management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Form 10-KT.  Based on such evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of December 31, 2015, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Controls over Financial Reporting

From time to time, we may review and make changes to our internal control over financial reporting that are intended to enhance the effectiveness of our internal control over financial reporting and which do not have a material effect on our overall internal control over financial reporting.  During the two months ended December 31, 2015, we made no changes to our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that we believe materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting.  Internal control over financial reporting, as defined in rules promulgated under the Exchange Act, is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and affected by our Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Consolidated Financial Statements for external purposes in accordance with GAAP.  Internal control over financial reporting includes those policies and procedures that:

- Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

- Provide reasonable assurance that transactions are recorded as necessary to permit preparation of Consolidated Financial Statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and our Board of Directors; and

- Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our Consolidated Financial Statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations.  Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures.  Internal control over financial reporting can also be circumvented by collusion or improper override.  Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting.  However, these inherent limitations are known features of the financial reporting process, and it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2015.  In making its assessment, management used the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO in its 2013 Internal Control — Integrated Framework.  Based on its assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2015.

The effectiveness of our internal control over financial reporting as of December 31, 2015 has been audited by Cherry Bekaert LLP, an independent registered public accounting firm, as stated in their report in Item 8 of this Transition Report on Form 10-KT.

Exhibit 10.74

NORTH CAROLINA
	FIRST AMENDMENT TO
WAKE COUNTY	LEASE AGREEMENT

This First Amendment to Lease Agreement (this “Amendment”) is entered into on this ___ day of August, 2015 by and between CCP Concourse, LLC, a Virginia limited liability company (“Landlord”); and Tenax Therapeutics, Inc., a Delaware corporation (“Tenant”) (this Amendment, all previous amendments or modifications to the Original Lease and the Original Lease are collectively referred to as the “Lease”).  The capitalized terms which are not defined herein shall have the same meaning as otherwise set out in the Lease.

WITNESSETH:

WHEREAS, Concourse Associates, LLC, a North Carolina limited liability company, (predecessor to Landlord) and Oxygen Biotherapeutics, Inc., a North Carolina corporation, (predecessor to Tenant) entered into an Office Lease Agreement dated January 27, 2011, for 5,954 rentable square feet (“RSF”) known as Suite 490 (“Premises”) in a building known as The Concourse Building (“Building”) located at One Copley Parkway, Morrisville, North Carolina.

WHEREAS, Landlord and Tenant desire to enter into this Amendment for the purpose of revising certain terms of the Lease, including extension of the Lease Term, as set out with specificity below.

NOW, THEREFORE, in consideration of these promises and other good and valuable consideration receipt of which is hereby acknowledged, the parties agree as follows:

1.           Recitals.  The foregoing recitals are true, accurate and are incorporated herein by reference.

2.           Commencement Date.  The Commencement Date for this Amendment shall be the later of (i) March 1, 2016, or (ii) the date on which the Tenant Improvements (as defined in Section 8 herein) shall have been Substantially Completed (“Commencement Date”).  If Landlord is delayed in Substantial Completion of the Tenant Improvements (as defined herein) as a result of the occurrence of Tenant Delay (as defined in Section 8 herein), then, for purposes of determining the Commencement Date, the date of Substantial Completion shall be deemed to be the day that the Tenant Improvements would have been completed absent such delays.  “Substantial Completion” or “Substantially Completed” means the Tenant Improvements have been completed according to the approved plans and specifications (other than details of construction, mechanical adjustment or other “punch list” items, the non-completion of which does not materially interfere with Tenant’s use of the Premises) and the issuance of a Certificate of Occupancy (either conditional or unconditional) from the appropriate governmental authority that certifies that the Premises may be occupied.  Any delay in delivery of the Premises beyond the target Commencement Date shall not subject Landlord to any liability for any loss or damages resulting therefrom.

3.           Lease Term.  Landlord and Tenant hereby agree to renew the Lease Term for sixty-four (64) consecutive months from the Commencement Date and continuing through and including twelve o’clock noon on the later of (i) June 30, 2021, or (ii) the last day of the sixty-fourth (64th) full month after the Commencement Date.

4.           Premises.  The Premises are located on the Fourth Floor of the Building, as shown on Exhibit A attached hereto and incorporated herein by reference.  The RSF of the Premises is deemed to be 5,954 RSF, and the parties agree that 5,954 RSF shall be used for all purposes under the Lease.  Landlord and Tenant acknowledge and agree that the Building measures 131,553 RSF and Tenant’s Pro Rata Share of Operating Expenses is 4.526%.

5.           Rent.

(a)           Tenant hereby agrees to pay Landlord annual Base Rent payable monthly in advance in the amount set out below and otherwise pursuant to the terms of the Lease:

Period			Base Rental Rate Per RSF		Monthly Payment		Annual Base Rent
	1 – 4	*	$	18.50	$	0.00	$	0.00
	5 – 12		$	18.50	$	9,179.08	$	73,432.64
	13 – 24		$	18.96	$	9,407.32	$	112,887.84
	25 – 36		$	19.43	$	9,640.52	$	115,686.24
	37 – 48		$	19.92	$	9,883.64	$	118,603.68
	49 – 60		$	20.42	$	10,131.72	$	121,580.64
	61 – 64		$	20.93	$	10,384.77	$	41,539.08
					TOTAL RENT:		$	583,730.12

*Annual Base Rent subject to four (4) month rent abatement described in Section 6 herein.

(b)           Additional Rent.  Tenant shall pay Landlord Additional Rent under the same terms and conditions described in Lease Addendum Number Two of the current Lease, as amended, except the Base Year as of the Effective Date is 2016.

6.           Rent Abatement.  Provided Tenant is not in default of the terms of the Lease, Landlord shall abate payment of the monthly rent installment due for the first four (4) months immediately following the Commencement Date.

Landlord and Tenant acknowledge that any period of reduced or abated rent described herein (the “Reduced Rent Period”) is based on Landlord’s expectation that Tenant will occupy, and pay Base Rent with respect to, the Premises for the entire duration of the Lease Term, and that if the Lease is terminated prior thereto, Landlord will be deprived of essential consideration for Landlord’s agreement to grant such reduced or abated rent.  Accordingly, if (i) Tenant breaches any term or covenant required to be performed by Tenant under the Lease beyond any applicable notice and cure period, or (ii) the Lease is otherwise terminated prior to expiration of the Lease Term for reasons other than Landlord’s default, Landlord shall have the right to rescind all such reductions or abatements of rent granted hereunder, and to recover from Tenant as of the termination date of this Lease (in addition to any other sums recoverable from or payable by Tenant in connection therewith) an amount equal to the amount of Base Rent which would have been payable during the months in which rent was abated had Tenant been required to pay for each month thereof the amount of Base Rent otherwise due for the Lease Term.

7.           Renewal Option.  Section 32 of the current Lease, as amended, is deleted in its entirety and replaced with the following:

Provided Tenant is not in default of the terms of the Lease, Tenant shall have two (2) renewal options for five (5) years each commencing on July 1, 2021, and ending at twelve o’clock noon on June 30, 2026 (“First Renewal Period”) and, if the Lease is not terminated sooner, a second renewal period commencing on July 1, 2026, and ending at twelve o’clock noon on June 30, 2031 (“Second Renewal Period”).  As a condition of Tenant’s exercise of this option, Tenant must satisfy the following conditions:

(a)           Tenant must notify Landlord, in writing, of its intention to exercise its renewal option not later than six (6) months prior to the expiration of the Lease Term or First Renewal Period.

(b)           The Base Rental rate during the initial year of each Renewal Period shall equal the Current Market Base Rental Rate, as defined in Exhibit C which is attached hereto and incorporated herein by reference.

(c)           Tenant shall pay Landlord Additional Rent during each Renewal Period under the same terms and conditions as described in Section 5(b) herein.

(d)           Failure by Tenant to satisfy the conditions set out hereinabove for either the First or Second Renewal Periods shall result in the termination of either or both the Renewal Options.

8.             Tenant Improvements.  Landlord agrees to cause certain improvements to be made to the Leased Premises described in detail in the schematic plans attached hereto as Exhibit B (“Schematic Plans”) and incorporated herein by reference (“Tenant Improvements”).  Landlord and Tenant acknowledge and agree that Landlord shall cause a cost estimate of the Tenant Improvements (“Cost Estimate”) to be performed by a general contractor acceptable to Landlord.  Provided the Cost Estimate is acceptable to Landlord, in its reasonable discretion, Tenant Improvements shall be made at Landlord’s sole expense.  Tenant shall bear the cost of Tenant Improvements approved in the Schematic Plans which exceed the Cost Estimate.  Any deviation from the Schematic Plans agreed to by Tenant and Landlord will require a change order signed by Tenant and Landlord detailing the nature and scope and cost of the change and designation of the party responsible to pay such cost.  Any and all costs arising from a deviation from the Plans and Specifications shall be the responsibility of and paid in full by Tenant upon delivery to Tenant of an invoice for the amount of such increase in cost.  Landlord shall, at its sole expense, in causing any Tenant Improvement at the Premises, comply with all present and future laws, regulations, building codes and/or fire codes applicable to the Premises.

A “Tenant Delay” means any act or omission of Tenant or its agents, employees, vendors or contractors that actually delays substantial completion of the Tenant Improvements, including, without limitation, the following:

(1)           Tenant’s failure to furnish information or approvals within any time period specified in the Lease or this Amendment, including the failure to prepare or approve plans and specifications by any applicable due date;

(2)           Tenant’s selection of equipment or materials that have long lead times after first being informed by Landlord that the selection may result in a delay;

(3)           Changes requested or made by Tenant to previously approved plans and specifications;

(4)           The performance of work in the Premises by Tenant or Tenant’s contractor(s) during the performance of the Tenant Improvements; or

(5)           If the performance of any portion of the Tenant Improvements depends on the prior or simultaneous performance of work by Tenant, a delay by Tenant or Tenant’s contractor(s) in the completion of such work.

9.           Right of First Offer.  (a) Provided Tenant is not in default under the terms of the Lease, and subject to the rights of existing tenants, Landlord hereby grants to Tenant a right of first offer (“ROFO”) to take possession of any space within the fourth (4th) floor of the Building adjacent to the Premises that is or shall become available for direct lease by Landlord during the Lease Term (“Expansion Space”).  For purposes of the ROFO, Expansion Space will be considered “available for lease” if (1) no bona fide written lease agreement exists relative to such Expansion Space or (2) the Expansion Space is due to become vacant because a tenant’s lease has or will expire and tenant has not elected to renew the Lease.  Landlord will advise Tenant of Expansion Space that will become “available for lease” (“ROFO Notice”).  The ROFO shall be exercised within ten (10) days after Tenant’s receipt of a ROFO Notice.  Tenant may exercise the ROFO as to all or a portion of the available Expansion Space, provided the ROFO is exercised for no less than 1,000 RSF.

Should Tenant exercise the ROFO, Tenant shall take the Expansion Space under the same terms and conditions set out in the Lease for the Premises, except the Base Rental Rate per RSF paid by Tenant for such Expansion Space shall be equal to the then-current Base Rental Rate, as provided for in this Amendment, and subject to the same annual Base Rent increases thereafter.  Tenant’s Pro Rata Share of Operating Expenses shall be adjusted to include the Expansion Space.  Failure by Tenant to exercise its Right of First Offer within ten (10) days after receipt of a ROFO Notice shall be deemed a rejection by Tenant of the Expansion Space, and this Right of First Offer shall terminate and be of no further force and effect.

(b)  Provided Tenant is not in default of the terms of the Lease and Tenant has exercised its ROFO according to the terms and conditions set out herein, Landlord agrees to cause certain improvements to be made to the Expansion Space according to plans and specifications mutually agreed to Landlord and Tenant (“Expansion Space Tenant Improvements”).  The Expansion Space Tenant Improvements may not be amended without Landlord’s and Tenant’s prior written consent. The cost to Landlord of space planning, engineering or construction drawings, construction management fees, construction permits and all other actual out-of-pocket expenses incurred by Landlord in constructing Tenant Improvements shall be paid by Landlord in an amount not to exceed the actual cost per RSF incurred by Landlord to construct the Tenant Improvements for the Premises (“Allowance”).  Any and all costs of Expansion Space Tenant Improvements in excess of the Allowance shall be the responsibility of and paid in full by Tenant upon receipt of any invoice for the amounts in excess of the Allowance.  Any deviation from the plans and specifications agreed to by Tenant and Landlord will require a change order signed by Tenant and Landlord detailing the nature and scope and cost of the change and designation of the party responsible to pay such cost.  Any and all costs arising from a deviation from the approved plans and specifications shall be the responsibility of and paid in full by Tenant upon delivery to Tenant of an invoice for the amount of such increase in cost.  Tenant shall be responsible for any costs incurred to construct the Expansion Space Tenant Improvements arising as a result of Tenant Delay.

(c)  Base Rent and Additional Rent shall commence for Expansion Space on the date the Expansion Space Tenant Improvements are Substantially Completed (“Expansion Space Commencement Date”).  The Lease Term for the Premises and the Expansion Space shall be extended for a period of sixty (60) full months beginning on the Expansion Space Commencement Date.  If the Expansion Space Commencement Date is a date other than the first day of the month, then the term for the lease of the Expansion Space shall run for sixty (60) months from the first day of the first month immediately following the Expansion Space Commencement Date.

(d)  Upon Landlord’s request, Tenant shall execute and deliver a written agreement specifying the Expansion Space Commencement Date in substantially the form set out in Exhibit D attached hereto. Tenant shall execute an appropriate amendment to this Lease to reflect the addition of the Expansion Space to the Premises and any other modifications to the Lease related to the Expansion Space agreed to by Landlord and Tenant.

10.           Tenant Right to Early Termination.  Provided (i) Tenant shall not at the time be in default in the performance of the terms and conditions of the Lease, as amended, and (ii)Landlord has not provided Tenant a ROFO Notice with respect to potential Expansion Space, Tenant shall have the one-time right and option to terminate the Lease, as amended, at the end of the thirty-sixth (36th) month following the Commencement Date (“Termination Date”).  Said option to terminate shall be exercisable by Tenant’s giving written notice to Landlord of its exercise of such option delivered not later than ten (10) days after the Termination Date together with the payment of all unamortized brokerage commission, legal fees, and cost of Tenant Improvements paid by Landlord in association with this Amendment (together with interest thereon at the rate of eight percent (8%) per annum).  The effective date of termination shall be the last day of the third (3d) month after the Termination Date (“Effective Date”).  Tenant shall be bound by and comply with the terms and conditions of the Lease including, without limitation, payment of all sums due from Tenant to Landlord, through and including the Effective Date.

11.           Possession During Construction.  Tenant shall remain in possession of the existing Leased Premises pending completion of the Tenant Improvements.

12.           No Options or Inducements; Condition of Premises.  Tenant acknowledges and agrees that, as of the Commencement Date and notwithstanding anything to the contrary set forth in the Lease or this Amendment, Tenant shall have no extension, termination or other options whatsoever with regard to the Leased Premises or under the Lease, as amended by this Amendment, apart from the Renewal Option (as defined and described in Section 7 of this Amendment), the ROFO (as defined and described in Section 9 of this Amendment) and the Right of Early Termination (as defined and described in Section 10 of this Amendment).  Tenant further acknowledges and agrees that, apart from the Tenant Improvements, Renewal Option, ROFO and Right of Early Termination, Tenant is not and shall not be entitled to any allowances, concessions, upfit work or other inducements of any kind in connection with the Leased Premises or under the Lease, as amended by this Amendment.  In the latter regard, Tenant acknowledges and agrees that from and after the Commencement Date, apart from any portion of the Tenant Improvements remaining incomplete, Landlord is leasing the Leased Premises to Tenant “as is,” without any representations or warranties of any kind (including, without limitation, any express or implied warranties of merchantability, fitness or habitability) and without any obligation on the part of Landlord to alter, remodel, improve, repair or decorate the Leased Premises or any part thereof.

13.           Holding Over.  Section 26 of the current Lease, as amended, is deleted in its entirety and replaced with the following:

If Tenant holds over after the Expiration Date or other termination of the Lease, as amended, such holding over shall not be a renewal of this Lease but shall create a tenancy-at-sufferance.  Tenant shall continue to be bound by all the terms and conditions of this Lease, except that during the first thirty (30) days of such tenancy-at-sufferance Tenant shall pay to Landlord (i) Base Rent at the rate equal to one hundred fifty percent (150%) of that Base Rent provided for as of the immediate preceding expiration or termination date, and (ii) any and all Operating Expenses and other forms of Additional Rent Payable under this Lease.  In the event Tenant holds over for a period longer than thirty (30) days, Tenant shall be obligated to pay to Landlord (i) two hundred percent (200%) of that Base Rent provided for as of the immediate preceding expiration or termination date and (ii) any and all Operating Expenses and other forms of Additional Rent Payable under this Lease.  The increased Rent during such holding over is intended to compensate Landlord partially for losses, damages and expenses, including frustrating and delaying Landlord’s ability to secure a replacement tenant.  If Landlord loses a prospective tenant because Tenant fails to vacate the Premises or Expansion Space, if applicable, on the Expiration Date or other termination of the Lease, as amended, after notice to do so, then Tenant will be liable for such damages as Landlord can prove because of Tenant’s wrongful failure to vacate.

14.           Binding Effect. The amendments made to the Lease pursuant to this Amendment shall be binding upon the parties and their respective successors and assigns.

15.           Mutual Acknowledgment of Non-Existence of Claims. The Landlord and Tenant acknowledge that as of the date of this Amendment there are no known claims by either party against the other arising from their relationship as Landlord and Tenant pursuant to the terms of the Lease.

16.           Assignments.  Tenant represents and warrants to Landlord that Tenant has not previously assigned, sublet, transferred, conveyed or otherwise encumbered in any way, directly or indirectly, any or all of its interest under the Lease with respect to the Premises.

Exhibit C

Current Market Base Rental Rate

A.           The annual rental for the First Renewal Period shall be at a rate to be negotiated between Landlord and Tenant commencing with the beginning of the final year of the Lease Term established by this Amendment.  Landlord and Tenant shall endeavor in good faith within the next sixty (60) days to agree upon a rental rate for the First Renewal Period.  Such renewal rate shall include the amount of or formula to calculate annual increases during the renewal period in question.  However, if Landlord and Tenant are unable to agree within such sixty (60) day period, then Landlord and Tenant shall each within the next fifteen (15) days name an appraiser to represent them, and the two so appointed shall endeavor to jointly agree on the then current market rental value of the Premises.  As used in this Lease, “current market base rental value” shall mean the market annual net rental rate per square foot for the applicable space and for the time as to which such rate is being determined, that a willing tenant would pay and a willing landlord would accept, in arm’s length bona fide negotiations taking into consideration all relevant factors including, without limitation, the following factors: costs and benefits accruing directly or indirectly to Landlord and/or Tenant arising from a lease renewal compared to an initial lease; rent being charged in other similar office buildings located in Wake County, North Carolina for comparable tenants, for renewal leases then being entered into for comparable space to the Premises; location, quality, amenities, age and reputation of the buildings in which the space being compared is located; use and size of the space under comparison; location and/or floor level of the subject space and any comparison space within their respective buildings; extent of services provided or to be provided; extent and condition of leasehold improvements in the subject space and in any comparison space; abatements pertaining to the subject space and to any comparison space (including with respect to base rental, operating expense and/or real estate taxes); inclusion of parking charges in rental, if applicable; lease takeovers/assumptions by the landlord of the comparison space, if applicable; moving allowances granted, if any, in connection with the subject space and with respect to any comparison space; relocation allowances granted, if any, in connection with the subject space and with respect to the comparison space; club memberships granted, if any; construction, refurbishment and repainting allowances granted, if any, in connection with the subject space and with respect to any comparison space; any other concessions or inducements in connection with the subject space and with respect to any comparison space; term or length of lease of subject space and of any comparison space; overall creditworthiness of Tenant and Tenants in comparable space; the time the particular rental rate under consideration was agreed upon and became or is to become effective; and payment of a leasing commission, fees, bonuses or other compensation whether to Tenant’s representatives or to Landlord, or to any person or entity affiliated with Tenant or Landlord, or otherwise.  If either Landlord or Tenant fails to designate by written notice to the other its appraiser in the time stated, the one properly appointed shall be empowered to set the then current market rental value of the Premises.  If the two are appointed and are unable to agree within thirty (30) days after their appointment, they shall appoint a third appraiser, who shall be empowered to choose only one from the two appraisals to be the then current market rental value of the Premises.  If the two fail to agree on a third appraiser within ten (10) days, then the parties hereto shall request that a third appraiser be appointed by the American Arbitration Association.  Such appraiser so appointed shall choose only one from the two appraisals to be the then current market rental value of the Premises, and such value shall be the rental during the First Renewal Period.  Notwithstanding anything to the contrary in Section 7 of this Amendment, if the current market rental value has not been fixed within thirty (30) days of the time for exercise of the renewal option, the time for exercise of such option shall be extended to the date thirty (30) days after the current market rental value has been determined.   All appraisers must be MAI qualified with at least ten (10) years experience with commercial office space in the Research Triangle Park, North Carolina area.   Each party shall bear the costs of its own appraiser; all other costs of the third appraiser and the arbitration shall be shared equally between Landlord and Tenant.

           B.           If Tenant is entitled to exercise its option for a Second Renewal Period and Tenant satisfies the conditions for exercise of the Second Renewal Option, the parties shall use the same procedure for fixing rent for such Second Renewal Period as is provided for the First Renewal Period.

NOTE A-DESCRIPTION OF BUSINESS

Description of Business—Tenax Therapeutics (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 was 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. On September 19, 2014, the Company changed its name to Tenax Therapeutics, Inc.

On October 18, 2013, the Company created a wholly owned subsidiary, Life Newco, Inc., a Delaware corporation (“Life Newco”), to acquire certain assets of Phyxius Pharma, Inc., a Delaware corporation (“Phyxius”), pursuant to an Asset Purchase Agreement, dated October 21, 2013 (the “Asset Purchase Agreement”), by and among the Company, Life Newco, Phyxius and the stockholders of Phyxius (the “Phyxius Stockholders”).  As further discussed in Note D below, on November 13, 2013, under the terms and subject to the conditions of the Asset Purchase Agreement, Life Newco acquired certain assets, including a license granting Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada.

B. SUMMARY OF CRITICAL ACCOUNTING POLICIES

8 Months Ended

Dec. 31, 2015

Accounting Policies [Abstract]

NOTE B-SUMMARY OF CRITICAL ACCOUNTING POLICIES

Use of Estimates

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

On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company’s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company’s results of operations and financial position could be materially impacted.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts and transactions of Tenax Therapeutics, Inc. and Life Newco, Inc. All material intercompany transactions and balances have been eliminated in consolidation.

Goodwill

Acquired businesses are accounted for using the acquisition method of accounting, which requires that assets acquired, including identifiable intangible assets, and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. If the acquired net assets do not constitute a business, the transaction is accounted for as an asset acquisition and no goodwill is recognized.

Goodwill is reviewed for impairment on an annual basis or more frequently if events or circumstances indicate potential impairment. The Company’s goodwill evaluation is based on both qualitative and quantitative assessments regarding the fair value of goodwill relative to its carrying value. The Company assesses qualitative factors to determine if its sole reporting unit’s fair value is more likely than not to exceed its carrying value, including goodwill. In the event the Company determines that it is more likely than not that its reporting unit’s fair value is less than its carrying amount, quantitative testing is performed comparing recorded values to estimated fair values. If the fair value exceeds the carrying value, goodwill is not impaired. If the carrying value exceeds the fair value, an impairment charge is recognized through a charge to operations based upon the excess of the carrying value of goodwill over the implied fair value.  There was no impairment to goodwill recognized during 2015 and 2014.

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.

Cash Concentration Risk

On July 21, 2010, the Wall Street Reform and Consumer Protection Act permanently increased the Federal Deposit Insurance Corporation (the “FDIC”) insurance limits to $250,000 per depositor per insured bank. The Company had cash balances of $7,190,971 and $58,038,597 uninsured by the FDIC as of April 30, 2015 and 2014, respectively.

At December 31, 2015, the Company had $2,908,446 of cash balances uninsured by the FDIC.

Liquidity and Capital Resources

The Company has financed its operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. The Company had total current assets of $20,560,353; $17,511,176 and $58,966,033 and working capital of $15,958,723; $12,993,966 and $56,394,986 as of December 31, 2015, April 30, 2015 and April 30, 2014, respectively.

Cash resources, including the fair value of the Company’s available for sale marketable securities as of December 31, 2015 were approximately $38.2 million, compared to approximately $48.1 million as of April 30, 2015, and approximately $58.3 million as of April 30, 2014.

Based on its resources at December 31, 2015, and the current plan of expenditure on continuing development of the Company’s current product candidates, the Company believes that it has sufficient capital to fund its operations through the calendar year 2017. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot assure that it will be able to secure such additional financing, or if available, that it will be sufficient to meet its needs.

To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates, or grant licenses on terms that may not be favorable to the Company. Any or all of the foregoing may have a material adverse effect on the Company’s business and financial performance.

Deferred financing costs

Deferred financing costs represent legal, due diligence and other direct costs incurred to raise capital or obtain debt. Direct costs include only “out-of-pocket” or incremental costs directly related to the effort, such as a finder’s fee and accounting and legal fees. These costs will be capitalized if the efforts are successful, or expensed when unsuccessful. Indirect costs are expensed as incurred. Deferred financing costs related to debt are amortized over the life of the debt. Deferred financing costs related to issuing equity are charged to Additional Paid-in Capital.

Derivative financial instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible promissory note instruments and other convertible equity instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under FASB ASC 815, Derivatives and Hedging (“ASC 815”) to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results.

Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments, and are evaluated and accounted for in accordance with the provisions of ASC 815.

Beneficial conversion and warrant valuation

In accordance with FASB ASC 470-20, Debt with Conversion and Other Options, the Company records a beneficial conversion feature (“BCF”) related to the issuance of convertible debt that have conversion features at fixed rates that are in-the-money when issued and the fair value of warrants issued in connection with those instruments. The BCF for the convertible instruments is recognized and measured by allocating a portion of the proceeds to warrants, based on their relative fair value, and as a reduction to the carrying amount of the convertible debt equal to the intrinsic value of the conversion feature. As described in Note F, the discount recorded in connection with the BCF and warrant valuation is recognized as non-cash interest expense and is amortized over the life of the convertible note.

Preclinical Study and Clinical Accruals

The Company estimates its preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and contract research organizations (“CROs”) that conduct and manage preclinical and clinical trials on its behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:

- Fees paid to CROs in connection with clinical trials,

- Fees paid to research institutions in conjunction with preclinical research studies, and

- Fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.

Property and Equipment, Net

Property and equipment are stated at cost, subject to adjustments for impairment, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the following estimated useful lives:

Laboratory equipment	3 – 5 years
Office equipment	5 years
Office furniture and fixtures	7 years
Computer equipment and software	3 years
Leasehold improvements	Shorter of useful life or remaining lease term

Maintenance and repairs are charged to expense as incurred, improvements to leased facilities and equipment are capitalized.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Revenue Recognition

Revenues from merchandise sales are recognized upon transfer of ownership, including passage of title to the customer and transfer of the risk of loss related to those goods.  Revenues are reported on a net sales basis, which is computed by deducting from gross sales the amount of actual product returns received, discounts, incentive arrangements with retailers and an amount established for anticipated product returns.  The Company’s practice is to accept product returns from retailers only if properly requested, authorized and approved.  As a percentage of gross sales, returns were less than 5% in fiscal years 2014 and 2013.

Revenues from a cost-reimbursement grant sponsored by the United States Army (“Grant Revenue”), are recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.

Research and Development Costs

Research and development costs include, but are not limited to, (i) expenses incurred under agreements with CROs and investigative sites, which conduct our clinical trials and a substantial portion of our preclinical studies; (ii) the cost of manufacturing and supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements, equipment, laboratory and other supplies.  All research and development expenses are expensed as incurred.

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.

Stock-Based Compensation

The Company accounts for stock based compensation in accordance with ASC 718 Compensation — Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based payment awards granted, modified and settled to our employees and directors. The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option on a straight-line basis over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.

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. Such amounts include shares potentially issuable under outstanding options, warrants and convertible debentures. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share follows.

Operating Leases

The Company maintains operating leases for its office and laboratory facilities. The lease agreements may include rent escalation clauses and tenant improvement allowances. The Company recognizes scheduled rent increases on a straight-line basis over the lease term beginning with the date the company takes possession of the leased space. Differences between rental expense and actual rental payments are recorded as deferred rent liabilities and are included in “Other liabilities” on the consolidated balance sheets.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board, or FASB, issued a new accounting standard intended to improve financial reporting about leasing transactions. The new standard will require the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leased assets. The new standard will also require it to provide enhanced disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from all leases, operating and capital, with lease terms greater than 12 month. The new standard is effective for financial statements beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted. See Note I for its current lease commitments. The Company is currently evaluating the impact that this new standard will have on our financial statements and related disclosures.

In January 2016, the FASB issued a new accounting standard that will enhance the Company’s reporting for financial instruments. The new standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier adoption is permitted for interim and annual reporting periods as of the beginning of the fiscal year of adoption. The Company does not believe the adoption of this standard will have a material impact on its consolidated financial statements.

In November 2015, the FASB issued a new accounting standard that changes the balance sheet classifications of deferred income taxes. This standard amends existing guidance to require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. It is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company does not expect adoption of this standard will have a material impact on its consolidated financial statements.

In April 2015, the FASB issued a new accounting standard that will change the reporting of debt issuance costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect adoption of this standard will have a material impact on its consolidated financial statements.

In August 2014, the FASB issued a new accounting standard that will require management to assess and evaluate whether conditions or events exist, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements issue date. It is effective for annual periods beginning after December 15, 2016 and for annual and interim periods thereafter; early adoption is permitted. The Company does not believe the adoption of this new standard to have a material effect on its consolidated financial statements.

In May 2014, the FASB issued a new accounting standard that supersedes nearly all existing revenue recognition guidance under GAAP. The new standard is principles-based and provides a five step model to determine when and how revenue is recognized. The core principle of the new standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. The new standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In July 2015, the FASB agreed to defer the effective date of the standard from annual periods beginning after December 15, 2016, to annual periods beginning after December 15, 2017, with an option that permits companies to adopt the standard as early as the original effective date. Early application prior to the original effective date is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and it does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.

Fair Value

The Company determines the fair value of its financial assets and liabilities in accordance with the FASB Accounting Standards Codification (“ASC”) 820 Fair Value Measurements. The Company’s balance sheet includes the following financial instruments: cash and cash equivalents, investments in marketable securities, short-term notes payable, and warrant liabilities. 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.

Accounting for fair value measurements involves a single definition of fair value, along with a conceptual framework to measure fair value, with a fair value defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The fair value measurement hierarchy consists of three levels:

Level one	Quoted market prices in active markets for identical assets or liabilities;
Level two	Inputs other than level one inputs that are either directly or indirectly observable; and
Level three	Unobservable inputs developed using estimates and assumptions; which are developed by the reporting entity and reflect those assumptions that a market participant would use.

The Company applies valuation techniques that (1) place greater reliance on observable inputs and less reliance on unobservable inputs and (2) are consistent with the market approach, the income approach and/or the cost approach, and include enhanced disclosures of fair value measurements in the Company’s consolidated financial statements.

Investments in Marketable Securities

The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive income/(loss), unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in other income (expense) in the Consolidated Statements of Operations and Comprehensive Loss and are determined using the specific identification method with transactions recorded on a settlement date basis.

The Company recognized a loss of $43,871 for the eight months ended December 31, 2015. For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $1,025, $0 and $0, respectively.

Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At December 31, 2015, the Company believes that the costs of its investments are recoverable in all material respects.

The following tables summarize the fair value of the Company’s investments by type. The estimated fair value of the Company’s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These fair values are obtained from independent pricing services which utilize Level 2 inputs:

	December 31, 2015
	Amortized Cost		Accrued Interest		Gross Unrealized Gains		Gross Unrealized Losses			Estimated Fair Value
Corporate debt securities	$	34,391,859	$	285,132	$	3,158	$	(132,601	)	$	34,547,548

The following table summarizes the scheduled maturity for the Company’s investments at December 31, 2015, April 30, 2015 and 2014, respectively:

	December 31, 2015		April 30, 2015		April 30, 2014
Maturing in one year or less	$	16,528,494	$	9,200,082	$	-
Maturing after one year through three years		18,019,054		30,974,961		-
Total investments	$	34,547,548	$	40,175,043	$	-

Warrant liability

On July 23, 2013, the Company issued common stock warrants in connection with the issuance of Series C 8% Preferred Stock (the “Series C Warrants”). As part of the offering, the Company issued 2,753,348 warrants at an exercise price of $2.60 per share and contractual term of 6 years. On November 11, 2013, the Company satisfied certain contractual obligations pursuant to the Series C offering which caused certain “down-round” price protection clauses in the outstanding warrants to become effective on that date. In accordance with ASC 815-40-35-9, the Company reclassified these warrants as a current liability and recorded a warrant liability of $1,380,883, which represents the fair market value of the warrants at that date. The initial fair value recorded as warrants within stockholders’ equity of $233,036 was reversed and the subsequent changes in fair value are recorded as a component of other expense.

Financial assets or liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. The Series C Warrants are measured using the Monte Carlo valuation model which is based, in part, upon inputs for which there is little or no observable market data, requiring the Company to develop its own assumptions.  The assumptions used in calculating the estimated fair value of the warrants represent the Company’s best estimates; however, these estimates involve inherent uncertainties and the application of management judgment.  As a result, if factors change and different assumptions are used, the warrant liabilities and the change in estimated fair value of the warrants could be materially different.

Inherent in the Monte Carlo valuation model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield.  The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.  The expected life of the warrants is assumed to be equivalent to their remaining contractual term.  The dividend rate is based on the historical rate, which the Company anticipates to remain at zero.

The Monte Carlo model is used for the Series C Warrants to appropriately value the potential future exercise price adjustments triggered by the anti-dilution provisions. This requires Level 3 inputs which are based on the Company’s estimates of the probability and timing of potential future financings and fundamental transactions.  The other assumptions used by the Company are summarized in the following table for the Series C Warrants that were outstanding as of December 31, 2015, April 30, 2015 and April 30, 2014:

Series C Warrants	December 31, 2015			April 30, 2015			April 30, 2014
Closing stock price	$	3.28		$	3.42		$	4.88
Expected dividend rate		0	%		0	%		0	%
Expected stock price volatility		84.08	%		83.53	%		90.32	%
Risk-free interest rate		1.44	%		1.23	%		1.75	%
Expected life (years)		3.56			4.23			5.23

As of December 31, 2015, the fair value of the warrant liability was $524,340. The Company recorded a gain of $48,105 for the change in fair value as a component of other expense on the condensed consolidated statement of comprehensive loss for the eight months ended December 31, 2015.

For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $382,431, a loss of $721,840 and $0, respectively, for the change in fair value as a component of other expense on the consolidated statement of operations.

A roll-forward of fair value measurements using significant unobservable inputs (Level 3) for the warrants for the eight months ended December 31, 2015 and the years ended April 30, 2015 and 2014 are as follows:

	For the year ended December 31, 2015

D. ACQUISITION

Business Combinations [Abstract]

NOTE D-ACQUISITION

On November 13, 2013, the Company, through its wholly owned subsidiary, Life Newco, acquired certain assets of Phyxius pursuant to the Asset Purchase Agreement. The acquisition was accounted for under the acquisition method of accounting for business combinations in accordance with FASB ASC 805,  Business Combinations, which requires, among other things that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date.  Acquisition-related costs are not included as a component of the acquisition accounting, but are recognized as expenses in the periods in which the costs are incurred.  Any changes within the measurement period resulting from facts and circumstances that existed as of the acquisition date may result in retrospective adjustments to the provisional amounts recorded at the acquisition date.

Under the terms and subject to the conditions of the Asset Purchase Agreement, Life Newco acquired (the “Acquisition”) certain assets, including that certain License Agreement (the “License”), dated September 20, 2013 by and between Phyxius and Orion Corporation, a global healthcare company incorporated under the laws of Finland (“Orion”), and that certain Side Letter, dated October 15, 2013 by and between Phyxius and Orion.  The License grants Life Newco an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial (the “Product”) in the United States and Canada (the “Territory”).  Pursuant to the License, Life Newco must use Orion’s “Simdax®” trademark to commercialize the Product.  The License also grants to Life Newco a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication.  Orion’s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the Territory, and certain regulatory participation rights.  Additionally, Life Newco must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by Life Newco under the License.  The License has a fifteen (15) year term, provided, however, that the License will continue after the end of the fifteen year term in each country in the Territory until the expiration of Orion’s patent rights in the Product in such country (the “Term”).  Orion had the right to terminate the License if the human clinical trial using the Product and studying reduction in morbidity and mortality of cardiac surgery patients at risk of low cardiac output syndrome (LCOS) as described in the US Food and Drug Administration (the “FDA”) agreed upon clinical study protocol (the “Study”) was not started by July 31, 2014. While the Company did not commence the trial by that date, on September 9, 2014, Orion notified the Company in writing that it did not intend to terminate the License so long as the trial was commenced on or before October 31, 2014.  The Company subsequently commenced the human clinical trial for levosimendan on September 18, 2014 when the first patient was enrolled.

The following table summarizes the consideration transferred to acquire Phyxius and the amounts of identified assets acquired and liabilities assumed at the acquisition date.

Fair Value of Consideration Transferred:

Common stock	8,747,802
Series E convertible preferred stock	15,299,198
Total	24,047,000

The Company issued 1,366,844 shares of its common stock that had a total fair value of approximately $8.7 million based on the closing market price on November 13, 2013, the acquisition date. The Company also issued 32,992 shares of its Series E Convertible Preferred Stock (the “Series E Stock”), which are convertible into an aggregate of 3,299,200 shares of common stock that had a total fair value of approximately $15.3 million.

The rights, preferences and privileges of the Series E Stock are set forth in the Certificate of Designation of Series E Convertible Preferred Stock that the Company filed with the Secretary of State of the State of Delaware on November 13, 2013.  Each share of Series E Stock automatically converted into 100 shares of common stock following receipt of stockholder approval for the transaction at the special meeting of stockholders held on March 13, 2014.  Approximately 11% of the shares of converted common stock vested immediately upon receipt of stockholder approval for the transaction, while the remainder vested upon the closing of the Company’s underwritten offering of 9,285,714 shares of common stock on March 21, 2014, which resulted in net proceeds of approximately $55 million.  

The Series E Stock was convertible into restricted common shares using a 100-for-one ratio at any time and in accordance with a vesting schedule contingent upon achievement of Company-specific non-financial conditions. As a result, the fair value of the Preferred Shares was inferred based on their common stock equivalent value given the conversion terms. The conditional vesting of the Series E Stock was accounted for by subtracting the fair value of an equal number of put options that would effectively protect the common stock equivalent stock value as of the closing date. The terms of the put options were as follows:

-   Exercise price equal to the common stock price as of the Valuation Date.

-   Term based on management’s risk-adjusted expected time to meeting the vesting condition, which was further increased by 6 months to reflect the marketability restriction of the unregistered stock, consistent with SEC Rule 144 of the Securities Act.

-   Volatility was consistent with the term for the individual milestone payments derived from the median historical asset volatility for a set of comparable guideline companies. The volatility was then relevered to estimate the equity volatility of the Company.

In accordance with the provisions of FASB ASC 805, the following table presents the preliminary allocation of the total fair value of consideration transferred, as discussed above, to the acquired tangible and intangible assets and assumed liabilities of Phyxius based on their estimated fair values as of the closing date of the transaction, measurement period adjustments recorded since the acquisition date and the adjusted allocation of the total fair value:

	November 13, 2013			Measurement			November 13, 2013
	(As initially reported)			Period Adjustments (1)			(As adjusted)
IPR&D	$	22,000,000		$	-		$	22,000,000
Trade and other payables		(256,000	)		-			(256,000	)
Liabilities arising from a contingency		(1,000,000	)		-			(1,000,000	)
Deferred tax liability related to intangibles acquired		-			(7,962,100	)		(7,962,100	)
Total identifiable net assets		20,744,000			(7,962,100	)		12,781,900
Goodwill		3,303,000			7,962,100			11,265,100
Total fair value of consideration	$	24,047,000		$	-		$	24,047,000

(1) The measurement period adjustments primarily reflect the recording of a deferred tax liability and resulting goodwill.  The measurement period adjustments were made to reflect facts and circumstances existing as of the acquisition date and did not result from intervening events subsequent to the acquisition date.

The fair value of the acquired in-process research and development, (“IPR&D”), intangible asset of approximately $22.0 million was determined using the multi-period excess earnings method. The Company did not acquire any other class of assets as a result of the acquisition.

Pursuant to the terms of the License, the Company paid to Orion a non-refundable up-front payment in the amount of $1 million.

The License also includes the following development milestones for which the Company shall make non-refundable payments to Orion no later than twenty-eight (28) days after the occurrence of the applicable milestone event: (i) $2.0 million upon the grant of FDA approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (ii) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the Territory. The Company must also pay Orion tiered royalties based on net sales of the Product in the Territory made by the Company and its sublicensees. After the end of the Term, the Company must pay Orion a royalty based on net sales of the Product in the Territory for as long as the Company sells the Product in the Territory.

In connection with the closing of the Acquisition, Phyxius’ co-founder, Chief Executive Officer and stockholder, John Kelley, became the Company’s Chief Executive Officer and two other Phyxius employees and stockholders, Doug Randall and Douglas Hay, PhD became employees of the Company as Vice President, Business and Commercial Operations and Vice President, Regulatory Affairs, respectively.  Michael Jebsen, the Company’s prior Interim Chief Executive Officer and current Chief Financial Officer, continued serving as the Company’s Chief Financial Officer.  In addition, Mr. Kelley was subsequently appointed to the Company’s Board of Directors, and Gerald T. Proehl, a designee of the Phyxius Stockholders, was appointed to the Board of Directors on April 3, 2014 following receipt of stockholder approval for the transaction.  Pursuant to the Asset Purchase Agreement, the Company agreed to propose that its stockholders approve an amendment to the Company’s 1999 Stock Plan to increase the amount of stock options authorized for issuance under the 1999 Stock Plan to not less than 4,000,000 shares of common stock. On March 13, 2014, the Company received stockholder approval to increase the option plan. In accordance with terms of the Acquisition, the Company issued an aggregate of 3,572,880 stock options with a grant date fair value of $15,818,512, to the individuals described above. See Note G for additional details.

The common stock and Series E Stock issued as the consideration in the Acquisition were issued and sold without registration under the Securities Act of 1933 (the “Securities Act”) in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws.  Accordingly, the Phyxius Stockholders may sell the shares of common stock and Series E Stock only pursuant to an effective registration statement under the Securities Act covering the resale of those securities, an exemption under Rule 144 under the Securities Act or another applicable exemption under the Securities Act.

The table below presents unaudited pro forma information as if the Company’s acquisition of Phyxius had occurred at the beginning of the earliest period presented, which was May 1, 2012.

There was no amortization expense for the eight months ended December 31, 2015.

For the fiscal years ended April 30, 2015, 2014, and 2013 the aggregate amortization expense on the above intangibles was $70,304, $62,189 and $55,845, respectively.

In Process Research and Development— The levosimendan product in Phase III clinical trial represents an IPR&D asset. The IPR&D asset is a research and development project rather than a product or processes already in service or being sold. Research and development intangible assets are considered indefinite-lived until the abandonment or completion of the associated research and development efforts. If abandoned, the assets would be impaired. Research and development expenditures that are incurred after the acquisition, including those for completing the research and development activities related to the acquired intangible research and development assets, are generally expensed as incurred.

Patents and License Rights—The Company currently holds, has filed for, or owns exclusive rights to, U.S. and worldwide patents covering 9 various methods and uses of its perfluorocarbon (“PFC”) technology. It capitalizes amounts paid to third parties for legal fees, application fees and other direct costs incurred in the filing and prosecution of its patent applications. These capitalized costs are amortized on a straight-line method over their useful life or legal life, whichever is shorter. For the fiscal years ended April 30, 2015, 2014, and 2013, the Company capitalized patent costs of approximately $105,000, $137,000 and $135,000, respectively.

The Company completed its annual impairment test of its patents and license rights during the fourth quarter of fiscal years 2015 and 2014. The Company wrote-off approximately $929,000 and $0 of capitalized costs for patent applications that were withdrawn or abandoned during the years ended April 30, 2015 and 2014, respectively. These asset impairment charges primarily related to the Company’s Oxycyte and other PFC formulations which were determined not to be a core component of the Company’s development strategy.

Trademarks—The Company currently holds, or has filed for, trademarks to protect the use of names and descriptions of its products and technology. It capitalizes amounts paid to third parties for legal fees, application fees and other direct costs incurred in the filing and prosecution of its trademark applications. These trademarks are evaluated annually for impairment in accordance with ASC 350, Intangibles – Goodwill and other. The Company evaluates (i) its expected use of the underlying asset, (ii) any laws, regulations, or contracts that may limit the useful life, (iii) the effects of obsolescence, demand, competition, and stability of the industry, and (iv) the level of costs to be incurred to commercialize the underlying asset. The Company wrote-off trademark costs of approximately $106,000 and $0, for the years ended April 30, 2015 and 2014, respectively. These asset impairment charges primarily related to the Company’s Oxycyte and other PFC formulations which were determined not to be a core component of the Company’s development strategy.

Convertible Note

On June 29, 2011, the Company issued a note (the “June Note”) with a principal amount of approximately $300,000 and Warrants to purchase 6,652 shares of common stock. On July 1, 2011, the Company issued a separate note (together with the June Note, the “Notes”) with a principal amount of $4,600,000 and warrants to purchase 101,996 shares of common stock. The aggregate gross proceeds to the Company from the offering were approximately $4.9 million, excluding any proceeds from the exercise of any warrants. The aggregate placement agent fees were $297,000 and legal fees associated with the offering were $88,839. These costs have been capitalized as debt issue costs and will be amortized as interest expense over the life of the Notes. The Company recorded amortization of debt issue costs of $21,427, $128,616 and $128,616 for the years ended April 30, 2015, 2014 and 2013, respectively. All debt issue costs were fully amortized in the first quarter of fiscal year ending April 30, 2015.

Interest on the Notes accrues at a rate of 15% annually and will be paid in quarterly installments commencing on the third month anniversary of issuance. The Notes were scheduled to mature 36 months from the date of issuance. The Notes may be converted into shares of common stock at a conversion price of $45.10 per share (subject to adjustment for stock splits, dividends and combinations, recapitalizations and the like) (the "Conversion Price") in whole or in part, at any time at the option of the holders of the Notes. The Notes also will automatically convert into shares of common stock at the Conversion Price at the election of a majority-in-interest of the holders of notes issued under the purchase agreement or upon the acquisition or sale of all or substantially all of the assets of the Company. The Company could make each applicable interest payment or payment of principal in cash, shares of common stock at the Conversion Price, or any combination thereof. The Company could elect to prepay all or any portion of the Notes without prepayment penalties only with the approval of a majority-in-interest of the note holders under the purchase agreement at the time of the election.   The Notes contained various events of default such as failing to timely make any payment under the Note when due, which would have resulted in all outstanding obligations under the Note becoming immediately due and payable.

On August 22, 2013 holders of $4.6 million of the Notes received 4,600 shares of the Company’s Series D 8% Convertible Preferred Stock (the “Series D Stock”) as consideration for cancelling their outstanding Notes. On that date, the Company recognized non-cash interest expense of $1,311,847 for the remaining unamortized debt discount associated with this Notes.

On June 29, 2014, the Company paid the remaining principal balance of $300,000 to the June Note holders upon maturity.

The Company recorded interest expense of $45,606, $2,181,955 and $2,507,156 for the years ended April 30, 2015, 2014 and 2013, respectively.

The total value allocated to the warrants was $1,960,497 and was recorded as a debt discount against the proceeds of the notes. In addition, the beneficial conversion features related to the Notes were determined to be $2,939,504.  As a result, the aggregate discount on the Notes totaled $4,900,001, and was amortized over the term of the notes. For the fiscal years ended April 30, 2015, 2014, and 2013, the Company recorded interest expense for the amortization of debt discount of $16,678, $483,330 and $1,633,332, respectively.

On August 22, 2013, the Company closed its private placement of an aggregate of $4.6 million of shares of the Company’s Series D Stock to JP SPC 3 obo OXBT FUND, SP (“OXBT Fund”).  In connection with the purchase of shares of Series D Stock, OXBT Fund received a warrant to purchase 2,358,975 shares of common stock at an exercise price equal to $2.60 (the “Series D Warrant”).  As consideration for the sale of the Series D Stock and Series D Warrant, $4.6 million in outstanding principal amount of a Note issued by the Company on July 1, 2011 and held by OXBT Fund was cancelled.  The Note carried interest at a rate of 15% per annum and matured on July 1, 2014.  Mr. Gregory Pepin, one of the Company’s directors, is the investment manager of OXBT Fund.  Pursuant to the terms of a lock-up agreement (the “Lock-Up Agreement”) executed prior to the closing, OXBT Fund and its affiliates are prohibited from engaging in certain transactions with respect to shares of the Company’s common stock and common stock equivalents until such time as the lead investor in the Company’s offering of Series C Stock ceases to own at least 25% of the shares of Series C Stock originally issued to such investor.

The table below sets forth a summary of the designation, powers, preferences and rights of the Series D Stock.

Conversion	Subject to certain ownership limitations, the Series D Stock is convertible at any time at the option of the holder into shares of the Company’s common stock at a conversion ratio determined by dividing the stated value of the Series C Stock (or $1,000) by a conversion price of $1.95 per share. The conversion price is subject to adjustment in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. Until such time that for at least 25 trading days during any 30 consecutive trading days, the volume weighted average price of the Company’s common stock exceeds 250% of the initial conversion price, if the Company sells or grants 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 then conversion price, or the Base Conversion Price, then the conversion price shall be reduced to equal the Base Conversion Price.
Dividends and Make-Whole Payment	Until the third anniversary of the date of issuance of the Series D Stock, the holder of the Series D Stock is entitled to receive dividends at the rate of 8% per annum of the stated value for each share of Series D Stock held by such holder payable quarterly on January 1, April 1, July 1 and October 1, beginning on the first such date after the original issue date, and on each dividend payment date.  The Company can elect to pay the dividends in cash or in duly authorized, validly issued, fully paid and non-assessable shares of common stock, or a combination thereof.  If the Company pays the dividends in shares of common stock, the shares used to pay the dividends will be valued at 90% of the average volume weighted average price for the 20 consecutive trading days ending on the trading day immediately prior to the applicable dividend payment date.  From and after the third anniversary of the date of issuance of the Series D Stock, the holder of Series D Stock will be entitled to receive dividends equal, on an as-if-converted to common stock basis, to and in the same form as dividends actually paid on shares of common stock when, as, and if such dividends are paid on shares of common stock.  The Company has never paid dividends on its common stock and the Company does not intend to do so for the foreseeable future. In the event OXBT Fund converts its Series D Stock prior to the third anniversary of the date of issuance of the Series D Stock, the Company must also pay to OXBT Fund in cash, or at the Company’s option in common stock valued as described above, or a combination of cash and shares of common stock, with respect to the Series D Stock so converted, an amount equal to $240 per $1,000 of the stated value of the Series D Stock, less the amount of any dividends paid in cash or in common stock on such Series D Stock on or before the date of conversion.
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 holder of Series D 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, 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.
Voting rights	Shares of Series D Stock will generally have no voting rights, except as required by law and except that the consent of the holder of the outstanding Series D Stock will, among other things, be required to amend the terms of the Series D Stock.

During the year ended April 30, 2014, 4,600 shares of Series D Stock were converted into 2,358,974 shares of common stock and the Company issued 576,084 shares of its common stock in the form of Series D Stock dividends.

On July 21, 2013, the Company entered into a Securities Purchase Agreement with certain investors providing for the issuance and sale by the Company (the “Series C Offering”) of an aggregate of approximately $5.4 million of shares of the Company’s Series C Stock, which are convertible into a combined total of 2,753,348 shares of common stock (the “Conversion Shares”).  In connection with the purchase of shares of Series C Stock in the Series C Offering, each investor will receive a warrant to purchase a number of shares of common stock equal to 100% of the number of Conversion Shares at an exercise price equal to $2.60 (the “Warrants”).  On July 23, 2013, the Company sold 5,369 units for net proceeds of approximately $4.9 million.

The table below sets forth a summary of the designation, powers, preferences and rights of the Series C Stock.

The conversion price is subject to adjustment in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. Until such time that for at least 25 trading days during any 30 consecutive trading days, the volume weighted average price of the Company’s common stock exceeds 250% of the initial conversion price, if the Company sells or grants 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 then conversion price, or the Base Conversion Price, then the conversion price shall be reduced to equal the Base Conversion Price.
Dividends and Make-Whole Payment	Until the third anniversary of the date of issuance of the Series C Stock, each holder of the Series C Stock is entitled to receive dividends at the rate of 8% per annum of the stated value for each share of Series C Stock held by such holder payable quarterly on January 1, April 1, July 1 and October 1, beginning on the first such date after the original issue date, and on each dividend payment date.  The Company can elect to pay the dividends in cash or in duly authorized, validly issued, fully paid and non-assessable shares of common stock, or a combination thereof.  If the Company pays the dividends in shares of common stock, the shares used to pay the dividends will be valued at 90% of the average volume weighted average price for the 20 consecutive trading days ending on the trading day immediately prior to the applicable dividend payment date.  From and after the third anniversary of the date of issuance of the Series C Stock, each holder of Series C Stock will be entitled to receive dividends equal, on an as-if-converted to common stock basis, to and in the same form as dividends actually paid on shares of common stock when, as, and if such dividends are paid on shares of common stock.  The Company has never paid dividends on its common stock and the Company does not intend to do so for the foreseeable future. In the event a holder converts his, her or its Series C Stock prior to the third anniversary of the date of issuance of the Series C Stock, the Company must also pay to the holder in cash, or at the Company’s option in common stock valued as described above, or a combination of cash and shares of common stock, with respect to the Series C Stock so converted, an amount equal to $240 per $1,000 of the stated value of the Series C Stock, less the amount of any dividends paid in cash or in common stock on such Series C Stock on or before the date of conversion.
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 C 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, 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.
Voting rights	Shares of Series C Stock will generally have no voting rights, except as required by law and except that the consent of holders of a majority of the outstanding Series C Stock will, among other things, be required to amend the terms of the Series C Stock.

On February 22, 2013, the Company entered into a Securities Purchase Agreement with an institutional investor providing for the issuance and sale by the Company of $1.6 million of shares of the Company’s Series B-1 Stock and $0.5 million of shares of the Company's Series B-2 Stock which are convertible into a combined total of 420,000 shares of common stock, subject to adjustment for subsequent equity sales.

The shares of Series B Stock were immediately convertible upon issuance.

The table below sets forth a summary of the designation, powers, preferences and rights of the Series B Stock.

Dividends	No dividends shall be paid on shares of Preferred Stock.
Conversion	Holders may elect to convert shares of Series B Stock into shares of common stock at the then-existing conversion price at any time.  The initial conversion price is $5.00 per share of common stock, and is subject to certain adjustments, including an anti-dilution provision that reduces the conversion price upon the issuance of any common stock or securities convertible into common stock at an effective price per share less than the conversion price and a one-time price reset following the effectiveness of a reverse split of the Company’s outstanding common stock.
Liquidation preference	In the event of the Company’s voluntary or involuntary dissolution, liquidation or winding up, each holder of Series B Stock will be entitled to be paid a liquidation preference equal to the initial stated value of such holder’s Series B Stock of $1,000 per share, plus accrued and unpaid dividends and any other payments that may be due on such shares, before any distribution of assets may be made to holders of capital stock ranking junior to the Series B Stock.
Voting rights	Shares of Series B Stock will generally have no voting rights, except as required by law and except that the consent of holders of a majority of the outstanding Series B Stock will among other things, be required to amend the terms of the Series B Stock.

The Company will not affect any conversion of the Series B Stock, nor shall a holder convert its shares of Series B Stock, to the extent that such conversion would cause the holder to have acquired, through conversion of the Series B Stock or otherwise, beneficial ownership of a number shares of common stock in excess of 4.99% of the common stock outstanding immediately preceding the conversion.

During the year ended April 30, 2014, 987 shares of Series B Stock were converted into 644,915 shares of common stock. As of December 31, 2015, April 30, 2015 and April 30, 2014 there were no shares of Series B Stock outstanding.

At the time of filing the Certificates of Elimination, no shares of preferred stock remained outstanding. As of December 31, 2015, 10,000,000 shares of preferred stock are undesignated.

Common Stock

Warrants

On November 11, 2014, the Company issued common stock warrants in connection with the execution of a service agreement for investor relations and corporate communications. As part of the compensation under the agreement, the Company issued up to 175,000 warrants at an exercise price of $4.00 per share and contractual term of 5 years. The warrant is initially exercisable for 25,000 shares of common stock, and the number of shares of common stock exercisable under this warrant will be automatically increased by 50,000 upon the first occurrence of market price goals of $6.00, $8.00 and $10.00, respectively, during the eighteen month period beginning on the effective date. In accordance with ASC 815, these warrants are classified as equity and their estimated fair-value of $478,115 was recorded as an operating expense in the consolidated statement of operations and as additional paid in capital during the year ended April 30, 2015. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

Series D Warrants

On August 22, 2013, the Company closed its private placement of an aggregate of $4.6 million shares of the Company’s Series D Stock to OXBT Fund.  In connection with the purchase of shares of Series D Stock, OXBT Fund received the Series D Warrant to purchase 2,358,975 shares of common stock at an exercise price equal to $2.60 and contractual term of 6 years. In accordance with ASC 815, these warrants are classified as equity and their relative fair-value of $1,531,167 was recognized as a deemed dividend on the Series D Stock during the year ended April 30, 2014. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.  

The Series D Warrant is exercisable beginning on the date of issuance and expires on August 22, 2019.  The exercise price and the number of shares issuable upon exercise of Series D Warrant is subject to appropriate adjustment in the event of recapitalization events, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company’s common stock, and also upon any distributions of assets, including cash, stock or other property to the Company’s stockholders.  In addition, if stockholder approval for the transaction is obtained, the Series D Warrant will be subject to anti-dilution provisions until such time that for 25 trading days during any 30 consecutive trading day period, the volume weighted average price of the Company’s common stock exceeds $6.50 and the daily dollar trading volume exceeds $350,000 per trading day.

On January 30, 2014, the Company entered into an agreement with the OXBT Fund to amend the terms of the outstanding Series D Warrants. The amendment replaced the price protection anti-dilution provision of each warrant with a covenant that the Company will not issue common stock or common stock equivalents at an effective price per share below the exercise price of such warrant without prior written consent, subject to certain exceptions.

The Series D Stock and the Series D Warrant were issued and sold without registration under the Securities Act in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws.  Accordingly, OXBT Fund may exercise the Warrant and sell the Series D Stock and underlying shares only pursuant to an effective registration statement under the Securities Act covering the resale of those securities, an exemption under Rule 144 under the Securities Act or another applicable exemption under the Securities Act.

During the year ended April 30, 2015, the Company received proceeds of $544,000 and issued 209,230 shares of common stock upon the exercise of the Series D warrants. As of December 31, 2015, 2,149,745 Series D Warrants are outstanding.

Series C Warrants

On July 23, 2013, as part of the offering of Series C Stock, the Company issued 2,753,348 Series C Warrants at an exercise price of $2.60 per share and contractual term of 6 years. In accordance with ASC 815, these warrants are classified as equity and their relative fair-value of $1,867,991 was recognized as a deemed dividend on the Series C Stock during the year ended April 30, 2014. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

In connection with the Series C Offering described above, the Company entered into a Placement Agency Agreement (the “Placement Agency Agreement”) with Ladenburg Thalmann & Co. Inc. (the “Placement Agent”) pursuant to which the Placement Agent agreed to act as the Company’s exclusive placement agent for the Series C Offering. In accordance with the Placement Agency Agreement, on July 23, 2013 the Company issued to the Placement Agent warrants to purchase 53,539 shares of common stock at an exercise price of $2.4375 per share and a contractual term of 3 years. In accordance with ASC 815, these warrants are classified as equity and their relative fair-value of $51,231 was recognized as additional paid in capital during the year ended April 30, 2014. The estimated fair value is determined using the Black-Scholes Option Pricing Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

During the year ended April 30, 2014, the Company received cash of approximately $6.5 million and issued 2,512,825 shares of common stock upon the exercise of outstanding Series C Warrants. As of December 31, 2015, 240,523 Series C Warrants are outstanding.

In accordance with ASC 815-40-35-8, the Company reassessed the classification of the remaining Series C Warrants. On November 11, 2013, the Company satisfied certain contractual obligations pursuant to the Series C offering which caused certain “down-round” price protection clauses in the outstanding warrants to become effective on that date. In accordance with ASC 815-40-35-9, on November 11, 2013, the Company reclassified these warrants as a current liability and recorded a warrant liability of $1,082,941 which represents the fair market value of the warrants at that date. The initial fair value recorded as warrants within stockholders’ equity of $233,036 was reversed and the change in fair value was recorded as a component of other expense.

The estimated fair value is determined using the Monte Carlo Model which is based on the value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrants, risk-free interest rates, expected dividends, expected volatility of the price of the underlying common stock as well as other estimates and assumptions.

As of December 31, 2015, the fair value of the warrant liability was $524,340. The Company recorded a gain of $48,105 for the change in fair value as a component of other expense on the consolidated statement of operations and comprehensive loss for the eight months ended December 31, 2015.

For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $382,431, a loss of $721,840 and $0, respectively, for the change in fair value as a component of other expense on the consolidated statements of operations and comprehensive loss.

The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.

The Company used the following assumptions to estimate the fair value of options granted under its stock option plans for the eight months ended December 31, 2015 and the fiscal years ended April 30, 2015, 2014 and 2013:

	For the eight months ended December 31,			For the year ended April 30
	2015			2015			2014			2013
Risk-free interest rate (weighted average)		1.99	%		2.23	%		1.80	%		1.29	%
Expected volatility (weighted average)		85.45	%		98.43	%		98.20	%		79.62	%
Expected term (in years)		7			7			6			7
Expected dividend yield		0.00	%		0.00	%		0.00	%		0.00	%

Risk-Free Interest Rate	The risk-free interest rate assumption was based on U.S. Treasury instruments with a term that is consistent with the expected term of the Company’s stock options.
Expected Volatility	The expected stock price volatility for the Company’s common stock was determined by examining the historical volatility and trading history for its common stock over a term consistent with the expected term of its options.
Expected Term	The expected term of stock options represents the weighted average period the stock options are expected to remain outstanding. It was calculated based on the historical experience that the Company has had with its stock option grants.
Expected Dividend Yield	The expected dividend yield of 0% is based on the Company’s history and expectation of dividend payouts. The Company has not paid and do not anticipate paying any dividends in the near future.
Forfeitures	As stock-based compensation expense recognized in the statement of operations for the eight months ended December 31, 2015 and the fiscal years ended April 30, 2015, 2014 and 2013 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on the Company’s historical experience.

The weighted-average grant-date fair value of options granted during the eight months ended December 31, 2015 was $3.25.

The weighted-average grant-date fair value of options granted during the years ended April 30, 2015, 2014 and 2013 was $4.82, $5.64 and $32.60, respectively.

The Company recorded compensation expense for these stock options grants of $217,736 for the eight months ended December 31, 2015.

As of December 31, 2015, there were unrecognized compensation costs of approximately $587,000 related to non-vested stock option awards that will be recognized on a straight-line basis over the weighted average remaining vesting period of 1.6 year. Additionally, there were unrecognized compensation costs of approximately $7.9 million related to non-vested stock option awards subject to performance-based vesting milestones with a weighted average remaining life of 4.3 years. As of December 31, 2015, none of these milestones have been achieved.

Inducement Stock Options

The table below summarizes the employment inducement stock option award for 25,000 shares of common stock made to our chief medical officer on February 15, 2015. This employment inducement stock option was awarded in accordance with the employment inducement award exemption provided by NASDAQ Rule 5635(c)(4) and was therefore not awarded under the Company’s stockholder approved equity plan. The option award will vest over a three year period, with one-third vesting per year, beginning one year from the grant date. The options have a 10-year term and an exercise price of $3.22 per share, the February 13, 2015 closing price of the Company’s common stock.

A summary of the activity and related information for our stock options follows:

	Number of Shares		Weighted Average Exercise Price
Inducement Stock Options outstanding at April 30, 2014		-	$	-
Options granted		25,000		3.22

Inducement Stock Options outstanding at December 31, 2015		25,000		3.22
Options exercisable at December 31, 2015		-	$	-

Inducement stock option compensation expense was approximately $26,000 for the eight months ended December 31, 2015.

For the years ended April 30, 2015, 2014 and 2013 Inducement stock option compensation expense totaled $9,830, $0 and $0, respectively.

At December 31, 2015, there was $28,300 of remaining unrecognized compensation expense related to the inducement stock options. Inducement stock options outstanding as of December 31, 2015 had a weighted average remaining contractual life of 9.13 years.

The estimated weighted average fair value per inducement option share granted was $64,343 in 2015 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: weighted average risk-free interest rate of 1.84%, dividend yield of 0%, volatility factor for our common stock of 93.90% and a weighted average expected life of 7 years for inducement options not forfeited.

Business Combinations [Abstract]

NOTE H-RESTRUCTURING EXPENSE

In May 2012, the Company decided to consolidate its operations and relocate its research and development function to North Carolina from Costa Mesa, California. To allow for this transition period, all existing development work had been completed and all of the manufacturing of the Company’s PFC-based products had been transferred to contract manufacturers. As part of these initiatives, the Company terminated all related research and development activities and a workforce reduction was implemented.  In September 2012, the Company entered into a sublease agreement with an unrelated third party that extends throughout the remaining term of the existing lease for the vacated facility.

The following table summarizes the impact of the work force reductions and other associated costs on operating expenses and payments for the eight months ended December 31, 2015, and the liability remaining on the balance sheet as of December 31, 2015.

Simdax license agreement

As further discussed in Note D above, on November 13, 2013 the Company acquired the License which granted it an exclusive, sublicenseable right to develop and commercialize pharmaceutical products containing Levosimedan in the United States and Canada.  Pursuant to the License, the Company must use Orion’s “Simdax®” trademark to commercialize the Product.  The License also grants to the Company a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication.  

Orion’s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the Territory, and certain regulatory participation rights.  Additionally, the Company must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by the Company under the License.  The License has a fifteen (15) year term, provided, however, that the License will continue after the end of the fifteen year term in each country in the Territory until the expiration of Orion’s patent rights in the Product in such country.  Orion had the right to terminate the License if the Study is not started by July 31, 2014.  While the Company did not commence the trial by that date, on September 9, 2014, Orion notified the Company in writing that it did not intend to terminate the License so long as the trial was commenced on or before October 31, 2014.  The Company subsequently commenced the human clinical trial for levosimendan on September 18, 2014 when the first patient was enrolled.

The License includes the following development milestones for which the Company shall make non-refundable payments to Orion no later than twenty-eight (28) days after the occurrence of the applicable milestone event: (i) $2.0 million upon the grant of FDA approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (ii) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the Territory.  The Company must also pay Orion tiered royalties based on net sales of the Product in the Territory made by the Company and its sublicensees. After the end of the Term, the Company must pay Orion a royalty based on net sales of the Product in the Territory for as long as Life Newco sells the Product in the Territory.

As of December 31, 2015, the Company has not met any of the developmental milestones and, accordingly, has not recorded any liability for the contingent payments due to Orion.

Agreement with Virginia Commonwealth University

In May 2008 the Company entered into a license agreement with Virginia Commonwealth University (“Licensor”, “VCU”) whereby it 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 unless the Company elects to terminate the agreement prior to patent expiration.  Under the agreement the Company has an obligation to diligently pursue product development and pursue, at its own expense, prosecution of the patent applications covered by the agreement. As part of the agreement, the Company is required to pay to VCU nonrefundable payments upon achieving development and regulatory milestones. As of April 30, 2015, the Company has not met any of the developmental milestones.

The agreement with VCU also requires the Company to pay royalties to VCU at specified rates based on annual net sales derived from the licensed technology. Pursuant to the agreement, the Company must make minimum annual royalty payments to VCU totaling $70,000 as long as the agreement is in force. These payments are fully creditable against royalty payments due for sales and sublicense revenue earned during the fiscal year as described above. This fee is recorded as an other current asset and is amortized over the fiscal year.  Amortization expense was $70,000 for each of the years ended April 30, 2015, 2014 and 2013.

In September 2014, the Company discontinued the development of its Oxycyte product candidates.  As part of the this change in business strategy, on May 5, 2015 the Company provided VCU its 90 day notice terminating the license agreement entered into with the Licensor, whose effective date was May 21, 2008.  The license agreement gave the Company exclusive rights to intellectual property that was used for the development and commercialization of Oxycyte and is therefore no longer needed.

Litigation

The Company is subject to litigation in the normal course of business, none of which management believes will have a material adverse effect on the Company’s Consolidated Financial Statements.

NOTE K-INCOME TAXES

The Company has not recorded any income tax expense (benefit) for the periods ended December 31, 2015, April 30, 2015 and April 30, 2014 due to its history of net operating losses.

The reconciliation of income tax expenses (benefit) at the statutory federal income tax rate of 34% for the periods ended December 31, 2015, April 30, 2015 and April 30, 2014 is as follows:

Net Deferred Tax Liabilities	$	(7,962,100	)	$	(7,962,100	)	$	(7,962,100	)

The Company has established a valuation allowance against net deferred tax assets due to the uncertainty that such assets will be realized. The Company periodically evaluates the recoverability of the deferred tax assets. At such time that it is determined that it is more likely than not that deferred tax assets will be realizable, the valuation allowance will be reduced.

As of December 31, 2015, the Company had Federal and State net operating loss carryforwards of approximately $105.3 million and $85.1 million available to offset future federal and state taxable income, respectively. The federal and state net operating loss carryforwards begin to expire in 2018 and valuation allowances have been provided.

Utilization of the net operating loss carryforwards may be subject to an annual limitation due to the ownership percentage change limitations provided by the Internal Revenue Code of 1986 and similar state provisions. The annual limitations may result in the expiration of the net operating losses before utilization.

Management has evaluated all other tax positions that could have a significant effect on the financial statements and determined the Company had no uncertain income tax positions at December 31, 2015.

The Company files U.S. and state income tax returns with varying statutes of limitations. The tax years 2001 and forward remain open to examination due to the carryover of unused net operating losses or tax credits.

B. SUMMARY OF CRITICAL ACCOUNTING POLICIES (Policies)

8 Months Ended

Dec. 31, 2015

Accounting Policies [Abstract]

Use of Estimates

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

On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company’s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company’s results of operations and financial position could be materially impacted.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts and transactions of Tenax Therapeutics, Inc. and Life Newco, Inc. All material intercompany transactions and balances have been eliminated in consolidation.

Goodwill

Acquired businesses are accounted for using the acquisition method of accounting, which requires that assets acquired, including identifiable intangible assets, and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. If the acquired net assets do not constitute a business, the transaction is accounted for as an asset acquisition and no goodwill is recognized.

Goodwill is reviewed for impairment on an annual basis or more frequently if events or circumstances indicate potential impairment. The Company’s goodwill evaluation is based on both qualitative and quantitative assessments regarding the fair value of goodwill relative to its carrying value. The Company assesses qualitative factors to determine if its sole reporting unit’s fair value is more likely than not to exceed its carrying value, including goodwill. In the event the Company determines that it is more likely than not that its reporting unit’s fair value is less than its carrying amount, quantitative testing is performed comparing recorded values to estimated fair values. If the fair value exceeds the carrying value, goodwill is not impaired. If the carrying value exceeds the fair value, an impairment charge is recognized through a charge to operations based upon the excess of the carrying value of goodwill over the implied fair value.  There was no impairment to goodwill recognized during 2015 and 2014.

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.

Cash Concentration Risk

On July 21, 2010, the Wall Street Reform and Consumer Protection Act permanently increased the Federal Deposit Insurance Corporation (the “FDIC”) insurance limits to $250,000 per depositor per insured bank. The Company had cash balances of $7,190,971 and $58,038,597 uninsured by the FDIC as of April 30, 2015 and 2014, respectively.

At December 31, 2015, the Company had $2,908,446 of cash balances uninsured by the FDIC.

Liquidity and Capital Resources

The Company has financed its operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. The Company had total current assets of $20,560,353; $17,511,176 and $58,966,033 and working capital of $15,958,723; $12,993,966 and $56,394,986 as of December 31, 2015, April 30, 2015 and April 30, 2014, respectively.

Cash resources, including the fair value of the Company’s available for sale marketable securities as of December 31, 2015 were approximately $38.2 million, compared to approximately $48.1 million as of April 30, 2015, and approximately $58.3 million as of April 30, 2014.

Based on its resources at December 31, 2015, and the current plan of expenditure on continuing development of the Company’s current product candidates, the Company believes that it has sufficient capital to fund its operations through the calendar year 2017. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot assure that it will be able to secure such additional financing, or if available, that it will be sufficient to meet its needs.

To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates, or grant licenses on terms that may not be favorable to the Company. Any or all of the foregoing may have a material adverse effect on the Company’s business and financial performance.

Deferred financing costs

Deferred financing costs represent legal, due diligence and other direct costs incurred to raise capital or obtain debt. Direct costs include only “out-of-pocket” or incremental costs directly related to the effort, such as a finder’s fee and accounting and legal fees. These costs will be capitalized if the efforts are successful, or expensed when unsuccessful. Indirect costs are expensed as incurred. Deferred financing costs related to debt are amortized over the life of the debt. Deferred financing costs related to issuing equity are charged to Additional Paid-in Capital.

Derivative financial instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible promissory note instruments and other convertible equity instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under FASB ASC 815, Derivatives and Hedging (“ASC 815”) to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results.

Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments, and are evaluated and accounted for in accordance with the provisions of ASC 815.

Beneficial conversion and warrant valuation

In accordance with FASB ASC 470-20, Debt with Conversion and Other Options, the Company records a beneficial conversion feature (“BCF”) related to the issuance of convertible debt that have conversion features at fixed rates that are in-the-money when issued and the fair value of warrants issued in connection with those instruments. The BCF for the convertible instruments is recognized and measured by allocating a portion of the proceeds to warrants, based on their relative fair value, and as a reduction to the carrying amount of the convertible debt equal to the intrinsic value of the conversion feature. As described in Note F, the discount recorded in connection with the BCF and warrant valuation is recognized as non-cash interest expense and is amortized over the life of the convertible note.

Preclinical Study and Clinical Accruals

The Company estimates its preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and contract research organizations (“CROs”) that conduct and manage preclinical and clinical trials on its behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:

- Fees paid to CROs in connection with clinical trials,

- Fees paid to research institutions in conjunction with preclinical research studies, and

- Fees paid to contract manufacturers and service providers in connection with the production and testing of active pharmaceutical ingredients and drug materials for use in preclinical studies and clinical trials.

Property and Equipment, Net

Property and equipment are stated at cost, subject to adjustments for impairment, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the following estimated useful lives:

Laboratory equipment	3 – 5 years
Office equipment	5 years
Office furniture and fixtures	7 years
Computer equipment and software	3 years
Leasehold improvements	Shorter of useful life or remaining lease term

Maintenance and repairs are charged to expense as incurred, improvements to leased facilities and equipment are capitalized.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Revenue Recognition

Revenues from merchandise sales are recognized upon transfer of ownership, including passage of title to the customer and transfer of the risk of loss related to those goods.  Revenues are reported on a net sales basis, which is computed by deducting from gross sales the amount of actual product returns received, discounts, incentive arrangements with retailers and an amount established for anticipated product returns.  The Company’s practice is to accept product returns from retailers only if properly requested, authorized and approved.  As a percentage of gross sales, returns were less than 5% in fiscal years 2014 and 2013.

Revenues from a cost-reimbursement grant sponsored by the United States Army (“Grant Revenue”), are recognized as milestones under the Grant program are achieved. Grant Revenue is earned through reimbursements for the direct costs of labor, travel, and supplies, as well as the pass-through costs of subcontracts with third-party CROs.

Research and Development Costs

Research and development costs include, but are not limited to, (i) expenses incurred under agreements with CROs and investigative sites, which conduct our clinical trials and a substantial portion of our preclinical studies; (ii) the cost of manufacturing and supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements, equipment, laboratory and other supplies.  All research and development expenses are expensed as incurred.

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.

Stock-Based Compensation

The Company accounts for stock based compensation in accordance with ASC 718 Compensation — Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based payment awards granted, modified and settled to our employees and directors. The Company chose the “straight-line” attribution method for allocating compensation costs of each stock option on a straight-line basis over the requisite service period using the Black-Scholes Option Pricing Model to calculate the grant date fair value.

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. Such amounts include shares potentially issuable under outstanding options, warrants and convertible debentures. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share follows.

Operating Leases

The Company maintains operating leases for its office and laboratory facilities. The lease agreements may include rent escalation clauses and tenant improvement allowances. The Company recognizes scheduled rent increases on a straight-line basis over the lease term beginning with the date the company takes possession of the leased space. Differences between rental expense and actual rental payments are recorded as deferred rent liabilities and are included in “Other liabilities” on the consolidated balance sheets.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board, or FASB, issued a new accounting standard intended to improve financial reporting about leasing transactions. The new standard will require the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leased assets. The new standard will also require it to provide enhanced disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from all leases, operating and capital, with lease terms greater than 12 month. The new standard is effective for financial statements beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted. See Note I for its current lease commitments. The Company is currently evaluating the impact that this new standard will have on our financial statements and related disclosures.

In January 2016, the FASB issued a new accounting standard that will enhance the Company’s reporting for financial instruments. The new standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Earlier adoption is permitted for interim and annual reporting periods as of the beginning of the fiscal year of adoption. The Company does not believe the adoption of this standard will have a material impact on its consolidated financial statements.

In November 2015, the FASB issued a new accounting standard that changes the balance sheet classifications of deferred income taxes. This standard amends existing guidance to require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. It is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company does not expect adoption of this standard will have a material impact on its consolidated financial statements.

In April 2015, the FASB issued a new accounting standard that will change the reporting of debt issuance costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect adoption of this standard will have a material impact on its consolidated financial statements.

In August 2014, the FASB issued a new accounting standard that will require management to assess and evaluate whether conditions or events exist, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements issue date. It is effective for annual periods beginning after December 15, 2016 and for annual and interim periods thereafter; early adoption is permitted. The Company does not believe the adoption of this new standard to have a material effect on its consolidated financial statements.

In May 2014, the FASB issued a new accounting standard that supersedes nearly all existing revenue recognition guidance under GAAP. The new standard is principles-based and provides a five step model to determine when and how revenue is recognized. The core principle of the new standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. The new standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In July 2015, the FASB agreed to defer the effective date of the standard from annual periods beginning after December 15, 2016, to annual periods beginning after December 15, 2017, with an option that permits companies to adopt the standard as early as the original effective date. Early application prior to the original effective date is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and it does not believe adoption of this standard will have a material impact on its consolidated financial statements and related disclosures.

Fair Value

The Company determines the fair value of its financial assets and liabilities in accordance with the FASB Accounting Standards Codification (“ASC”) 820 Fair Value Measurements. The Company’s balance sheet includes the following financial instruments: cash and cash equivalents, investments in marketable securities, short-term notes payable, and warrant liabilities. 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.

Accounting for fair value measurements involves a single definition of fair value, along with a conceptual framework to measure fair value, with a fair value defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The fair value measurement hierarchy consists of three levels:

Level one	Quoted market prices in active markets for identical assets or liabilities;
Level two	Inputs other than level one inputs that are either directly or indirectly observable; and
Level three	Unobservable inputs developed using estimates and assumptions; which are developed by the reporting entity and reflect those assumptions that a market participant would use.

The Company applies valuation techniques that (1) place greater reliance on observable inputs and less reliance on unobservable inputs and (2) are consistent with the market approach, the income approach and/or the cost approach, and include enhanced disclosures of fair value measurements in the Company’s consolidated financial statements.

Investments in Marketable Securities

The Company classifies all of its investments as available-for-sale. Unrealized gains and losses on investments are recognized in comprehensive income/(loss), unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in other income (expense) in the Consolidated Statements of Operations and Comprehensive Loss and are determined using the specific identification method with transactions recorded on a settlement date basis.

The Company recognized a loss of $43,871 for the eight months ended December 31, 2015. For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $1,025, $0 and $0, respectively.

Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. At December 31, 2015, the Company believes that the costs of its investments are recoverable in all material respects.

The following tables summarize the fair value of the Company’s investments by type. The estimated fair value of the Company’s fixed income investments are classified as Level 2 in the fair value hierarchy as defined in U.S. GAAP. These fair values are obtained from independent pricing services which utilize Level 2 inputs:

	December 31, 2015
	Amortized Cost		Accrued Interest		Gross Unrealized Gains		Gross Unrealized Losses			Estimated Fair Value
Corporate debt securities	$	34,391,859	$	285,132	$	3,158	$	(132,601	)	$	34,547,548

The following table summarizes the scheduled maturity for the Company’s investments at December 31, 2015, April 30, 2015 and 2014, respectively:

	December 31, 2015		April 30, 2015		April 30, 2014
Maturing in one year or less	$	16,528,494	$	9,200,082	$	-

Total investments	$	34,547,548	$	40,175,043	$	-

Warrant liability

On July 23, 2013, the Company issued common stock warrants in connection with the issuance of Series C 8% Preferred Stock (the “Series C Warrants”). As part of the offering, the Company issued 2,753,348 warrants at an exercise price of $2.60 per share and contractual term of 6 years. On November 11, 2013, the Company satisfied certain contractual obligations pursuant to the Series C offering which caused certain “down-round” price protection clauses in the outstanding warrants to become effective on that date. In accordance with ASC 815-40-35-9, the Company reclassified these warrants as a current liability and recorded a warrant liability of $1,380,883, which represents the fair market value of the warrants at that date. The initial fair value recorded as warrants within stockholders’ equity of $233,036 was reversed and the subsequent changes in fair value are recorded as a component of other expense.

Financial assets or liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. The Series C Warrants are measured using the Monte Carlo valuation model which is based, in part, upon inputs for which there is little or no observable market data, requiring the Company to develop its own assumptions.  The assumptions used in calculating the estimated fair value of the warrants represent the Company’s best estimates; however, these estimates involve inherent uncertainties and the application of management judgment.  As a result, if factors change and different assumptions are used, the warrant liabilities and the change in estimated fair value of the warrants could be materially different.

Inherent in the Monte Carlo valuation model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield.  The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants.  The expected life of the warrants is assumed to be equivalent to their remaining contractual term.  The dividend rate is based on the historical rate, which the Company anticipates to remain at zero.

The Monte Carlo model is used for the Series C Warrants to appropriately value the potential future exercise price adjustments triggered by the anti-dilution provisions. This requires Level 3 inputs which are based on the Company’s estimates of the probability and timing of potential future financings and fundamental transactions.  The other assumptions used by the Company are summarized in the following table for the Series C Warrants that were outstanding as of December 31, 2015, April 30, 2015 and April 30, 2014:

Series C Warrants	December 31, 2015			April 30, 2015			April 30, 2014
Closing stock price	$	3.28		$	3.42		$	4.88
Expected dividend rate		0	%		0	%		0	%
Expected stock price volatility		84.08	%		83.53	%		90.32	%
Risk-free interest rate		1.44	%		1.23	%		1.75	%
Expected life (years)		3.56			4.23			5.23

As of December 31, 2015, the fair value of the warrant liability was $524,340. The Company recorded a gain of $48,105 for the change in fair value as a component of other expense on the condensed consolidated statement of comprehensive loss for the eight months ended December 31, 2015.

For the fiscal years ended April 30, 2015, 2014 and 2013, the Company recognized a gain of $382,431, a loss of $721,840 and $0, respectively, for the change in fair value as a component of other expense on the consolidated statement of operations.

A roll-forward of fair value measurements using significant unobservable inputs (Level 3) for the warrants for the eight months ended December 31, 2015 and the years ended April 30, 2015 and 2014 are as follows:
