1. Description of Business

VistaGen Therapeutics, Inc., a Nevada corporation, is a clinical-stage biopharmaceutical company committed to developing and commercializing product candidates for patients with depression, other diseases and disorders related to the central nervous system (CNS), and cancer. Our principal executive offices are located at 343 Allerton Avenue, South San Francisco, California 94080, and our telephone number is (650) 577-3600. Our website address is www.vistagen.com. Unless the context otherwise requires, the words “VistaGen Therapeutics, Inc.” “VistaGen,” “we,” “the Company,” “us” and “our” refer to VistaGen Therapeutics, Inc., a Nevada corporation.

VistaGen Therapeutics, Inc., a California corporation incorporated on May 26, 1998 (VistaGen California), is our wholly-owned subsidiary. Pursuant to a strategic merger transaction on May 11, 2011, we acquired all outstanding shares of VistaGen California in exchange for 341,823 shares of our common stock (Merger), and assumed all of VistaGen California’s pre-Merger obligations. The Consolidated Financial Statements in this report also include the accounts of VistaGen California’s two wholly-owned subsidiaries, Artemis Neuroscience, Inc., a Maryland corporation, and VistaStem Canada, Inc., a corporation organized under the laws of Ontario, Canada.

Our lead product candidate, AV-101, is an orally-active small molecule prodrug in Phase 2 development for Major Depressive Disorder (MDD). AV-101’s mechanism of action (MOA), as an N-methyl-D-aspartate receptor (NMDAR) antagonist binding selectively at the glycine-binding (GlyB) co-agonist site of the NMDAR, is fundamentally different from all currently-approved antidepressants. In three preclinical studies utilizing well-validated animal models of depression, AV-101 was shown to induce fast-acting, dose-dependent, persistent and statistically significant antidepressant-like responses, following a single treatment, which were equivalent to response seen with a single sub-anesthetic dose of ketamine. In the same studies, fluoxetine did not induce rapid onset antidepressant-like responses. Preclinical studies also support the hypothesis that AV-101 has potential to treat several additional CNS disorders, including chronic neuropathic pain, epilepsy and neurodegenerative diseases, such as Parkinson’s disease and Huntington’s disease where modulation of the NMDAR may have therapeutic benefit.

Following our two successful randomized, double-blind, placebo-controlled Phase 1 safety studies funded by the U.S. National Institutes of Health (NIH), AV-101 is the only small molecule product candidate known to management that is (A) in Phase 2 clinical development as a monotherapy for MDD, (B) designed to modulate the NMDAR through antagonistic binding at the GlyB co-agonist site of the NMDAR and (C) orally-active in human subjects.

In February 2015, we entered a Cooperative Research and Development Agreement (CRADA) with the U.S. National Institute of Mental Health (NIMH), part of the NIH. Under this agreement, we will collaborate with the NIH on a Phase 2 clinical study of AV-101 in subjects with treatment resistant Major Depressive Disorder. Pursuant to the CRADA, this study will be conducted and fully-funded by the NIMH. It is contemplated that this clinical study will begin this year under the direction of Dr. Carlos Zarate, Jr., the NIMH’s Chief of Experimental Therapeutics & Pathophysiology Branch and of the Section on Neurobiology and Treatment of Mood and Anxiety Disorders.

In addition to developing AV-101 for MDD and other CNS indications, we are using our stem cell technology platform for drug rescue –to identify and develop proprietary new chemical entities (NCEs) for our internal drug candidate pipeline by leveraging our in vitro bioassay systems, prior investment by pharmaceutical companies and others to discover, optimize and test for efficacy NCEs terminated before FDA approval due to unexpected toxicity and medicinal chemistry. Our CardioSafe 3D™ bioassay system uses our human pluripotent stem cell (hPSC)-derived cardiomyocytes, or heart cells. Our LiverSafe 3D™bioassay system uses our stem cell-derived hepatocytes, or liver cells. We believe CardioSafe 3D and LiverSafe 3D offer a new paradigm for evaluating and predicting potential heart and liver toxicity of NCEs, including potential drug rescue NCEs, early in development, long before costly, high risk animal studies and human clinical trials. We intend to develop each optimized drug rescue NCE internally to establish in vitro and in vivo preclinical proof-of-concept (POC), as to both efficacy and safety, using both established in vitro and in vivo models, as well as in CardioSafe 3D and, when available, LiverSafe 3D.

Although we have previously generated approximately $16.4 million of revenue from grant awards and collaborations, we currently have no commercially available, revenue-generating products and, since inception, we have devoted substantially all of our time and efforts to development of AV-101 for CNS indications and our human pluripotent stem cell technology research and development programs, including, customized bioassay system development, creating, protecting and patenting intellectual property, recruiting personnel and raising working capital.

2. Basis of Presentation and Going Concern

Effective August 14, 2014, we consummated a 1-for-20 reverse split of our authorized, and issued and outstanding shares of common stock (the Stock Consolidation). Each reference to shares of common stock or the price per share of common stock in these financial statements is post-Stock Consolidation, and reflects the 1-for-20 adjustment as a result of the Stock Consolidation. See Note 8, Capital Stock, for more information regarding the Stock Consolidation.

The accompanying Consolidated Financial Statements have been prepared assuming that we will continue as a going concern. As a developing-technology company having not yet developed commercial products or achieved sustainable revenues, we have experienced recurring losses and negative cash flows from operations resulting in a deficit of $84.5 million accumulated from inception through March 31, 2015. We expect losses and negative cash flows from operations to continue for the foreseeable future as we engage in further potential development of AV-101 and launch and execute our drug rescue programs and pursue potential drug development and regenerative medicine opportunities.

Since our inception in May 1998 through March 31, 2015, we have financed our operations and technology acquisitions primarily through the issuance and sale of equity and debt securities, including convertible promissory notes and short-term promissory notes, for cash proceeds of approximately $29.0 million, as well as from an aggregate of approximately $16.4 million of government research grant awards, strategic collaboration payments and other revenues. Additionally, we have issued equity securities with an approximate value at issuance of $13.5 million in non-cash settlements of certain liabilities, including liabilities for professional services rendered to us or as compensation for such services.

Between late-March 2014 and March 31, 2015, we entered into securities purchase agreements with accredited investors and institutions, including Platinum, pursuant to which we sold units to such accredited investors, in private placement transactions (2014 Units or 2014 Unit Private Placement), for aggregate cash proceeds of approximately $3.1 million, consisting of (i) 2014 Unit Notes in the aggregate face amount of approximately $3.1 million which matured between March 31, 2015 and April 30, 2015, or were automatically convertible into securities we might issue upon the consummation of a Qualified Financing, as defined, (ii) an aggregate of 282,850 restricted shares of our common stock (2014 Unit Stock); and (iii) warrants exercisable through December 31, 2016 to purchase an aggregate of 282,850 restricted shares of our common stock at an exercise price of $10.00 per share (2014 Unit Warrants). At March 31, 2015, we did not have sufficient cash and cash equivalents to enable us to fund our planned operations, including expected cash expenditures of approximately $7 million over the next twelve months, including expenditures required to prepare for further clinical trials of AV-101.

As described more completely in Note 16, Subsequent Events, between April 1 and May 14, 2015, we continued the 2014 Unit Private Placement, pursuant to which we sold to accredited investors 2014 Units, for aggregate cash proceeds of $280,000, consisting of: (i) 10% convertible promissory notes maturing between April 30, 2015 and May 15, 2015, in the aggregate face amount of $280,000, (ii) an aggregate of 33,000 shares of our restricted common stock, and (iii) warrants exercisable through December 31, 2016 to purchase an aggregate of 24,250 restricted shares of our common stock at an exercise price of $10.00 per share. As also described more completely in Note 16, Subsequent Events, during May 2015, we entered into an agreement with Platinum (Platinum Agreement), pursuant to which, Platinum has, among other things:

· Converted the approximately $4.5 million outstanding balance (principal and accrued but unpaid interest) of the Senior Notes we issued to Platinum into 641,335 shares of our newly-created Series B 10% Convertible Preferred Stock (Series B Preferred) , thereby cancelling approximately $4.5 million of our outstanding indebtedness;

· Released all of its security interests in our assets and those of our subsidiaries by terminating the Amended and Restated Security Agreement, IP Security Agreement and Negative Covenant, which we had entered into with Platinum in October 2012; and

· Converted the approximately $1.3 million outstanding balance (principal and accrued but unpaid interest) of the convertible promissory notes we issued to Platinum in the 2014 Unit Private Placement (2014 Unit Notes) into 240,305 shares of Series B Preferred and five-year warrants to purchase 240,305 shares of our common stock at a fixed exercise price of $7.00 per share (Series B Warrants), thereby cancelling approximately $1.3 million of our outstanding indebtedness; and

· Purchased approximately $1.5 million (principal and accrued but unpaid interest) of outstanding 2014 Unit Notes we issued to various other investors from the respective holders thereof (Investor 2014 Unit Notes ) and converted the entire outstanding balance of the Investor 2014 Unit Notes into 265,699 shares of Series B Preferred and Series B Warrants to purchase 265,699 shares of our common stock, thereby cancelling approximately $1.5 million of our outstanding indebtedness; and

· Entered into a Securities Purchase Agreement (SPA) to purchase, for $1.0 million, a total of 142,857 shares of Series B Preferred and a Series B Warrant (Series B Preferred Unit) to purchase 142,857 shares of our common stock, on or before June 11, 2015 (a portion of which purchase was consummated on June 19, 2015).

As further described in Note 16, Subsequent Events, effective May 20, 2015, holders of the remaining $1.8 million outstanding balance (principal and accrued but unpaid interest) of 2014 Unit Notes converted such notes into 327,016 shares of Series B Preferred and Series B Warrants to purchase 327,016 shares of our common stock, thereby cancelling an additional approximately $1.8 million of our outstanding indebtedness. Between May 26, 2015 and June 25, 2015, we sold to accredited investors and institutions an aggregate of $557,500 of units in our Series B Preferred Unit offering, which units consist of Series B Preferred and Series B Warrants (together Series B Preferred Units), including $100,000 to Platinum. We issued 79,646 shares of Series B Preferred and Series B Warrants to purchase 79,646 shares of our common stock. We have received an aggregate of $557,500 in cash proceeds from the sale of the Series B Preferred Units.

Additionally, as further described in Note 16, Subsequent Events, holders of certain of our promissory notes outstanding at March 31, 2015 and thereafter, including Morrison & Foerster, Cato Research Ltd., University Health Network, and McCarthy Tetrault, and certain other service providers converted notes payable or accounts payable having an aggregate outstanding balance of approximately $5.8 million (principal and accrued but unpaid interest and certain strategic adjustments) into 831,577 shares of Series B Preferred stock.

Since March 31, 2015, we have eliminated approximately $14.9 million of promissory notes, other debt and certain adjustments thereto that was either already due and payable or would have otherwise matured prior to March 31, 2016, through conversion into our Series B Preferred stock and, with respect to a portion of the indebtedness converted, warrants to purchase common stock. Together with the cash proceeds from our Series B Preferred Unit Offering, our working capital position has improved significantly since March 31, 2015. We will, however, need to raise additional capital to fund our operations and execute our business plan over the next year and thereafter.

We believe that our participation in potential strategic collaborations, including potential transactions involving AV-101 such as our February 2015 Cooperative Research and Development Agreement with the U.S. National Institutes of Health (NIH) for an NIH-funded and sponsored Phase 2 study of AV-101 in major depressive disorder, may provide resources to support a portion of our future cash needs and working capital requirements. When and as necessary, we will seek to raise a material amount of financing through a combination of additional private placements and/or registered public offerings of our securities, which may include both debt and equity securities, stem cell technology-based research and development collaborations, stem cell technology and drug candidate license fees, and government grant awards and collaborations. Our future working capital requirements will depend on many factors, including, without limitation, the scope and nature of strategic opportunities related to our success in clinical trials of and further developing AV-101 as a treatment for major depressive disorder and/or other conditions; our stem cell technology platform, including drug rescue and cell therapy research and development efforts and the success of such programs, our ability to obtain government grant awards and our ability to enter into strategic collaborations with institutions on terms acceptable to us. To further advance the clinical development of AV-101 and potential drug rescue applications of our stem cell technology platform, as well as support our operating activities, we plan to continue to carefully manage our routine operating costs, including salaries and benefits, regulatory and public company consulting, contract research and development, legal, accounting and other professional services and working capital costs.

Notwithstanding the foregoing, substantial additional financing may not be available to us on a timely basis, on acceptable terms, or at all. If we are unable to obtain substantial additional financing on a timely basis in the near term, our business, financial condition, and results of operations may be harmed, the price of our stock may decline, we may be required to reduce, defer, or discontinue certain of our research and development activities and we may not be able to continue as a going concern. These Consolidated Financial Statements do not include any adjustments that might result from the outcome of this uncertainty.

Summary of Significant Accounting Policies

3. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include, but are not limited to, those relating to stock-based compensation, revenue recognition, and the assumptions used to value warrants, warrant modifications and warrant liabilities.

Principles of Consolidation

The accompanying consolidated financial statements include the Company’s accounts, and the accounts of VistaGen California’s wholly-owned inactive subsidiaries, Artemis Neurosciences and VistaStem Canada.

Cash and Cash Equivalents

Cash and cash equivalents are considered to be highly liquid investments with maturities of three months or less at the date of purchase.

Property and Equipment

Property and equipment is stated at cost. Repairs and maintenance costs are expensed in the period incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property and equipment range from five to seven years.

Impairment or Disposal of Long-Lived Assets

We evaluate our long-lived assets, primarily property and equipment, for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable from the estimated future cash flows expected to result from their use or eventual disposition. If the estimates of future undiscounted net cash flows are insufficient to recover the carrying value of the assets, we record an impairment loss in the amount by which the carrying value of the assets exceeds their fair value. If the assets are determined to be recoverable, but the useful lives are shorter than originally estimated, we depreciate or amortize the net book value of the assets over the newly determined remaining useful lives. We have not recorded any impairment charges to date.

Revenue Recognition

Although we do not currently have any such arrangements, we have historically generated revenue principally from collaborative research and development arrangements, technology transfer agreements, including strategic licenses, and government grants. Revenue arrangements with multiple components are divided into separate units of accounting if certain criteria are met, including whether the delivered component has stand-alone value to the customer. Consideration received is allocated among the separate units of accounting based on their respective selling prices. The selling price for each unit is based on vendor-specific objective evidence, or VSOE, if available, third party evidence if VSOE is not available, or estimated selling price if neither VSOE nor third party evidence is available. The applicable revenue recognition criteria are then applied to each of the units.

We recognize revenue when the four basic criteria of revenue recognition are met: (i) a contractual agreement exists; (ii) the transfer of technology has been completed or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured. For each source of revenue, we comply with the above revenue recognition criteria in the following manner:

• Collaborative arrangements typically consist of non-refundable and/or exclusive up front technology access fees, cost reimbursements for specific research and development spending, and various milestone and future product royalty payments. If the delivered technology does not have stand-alone value, the amount of revenue allocable to the delivered technology is deferred. Non-refundable upfront fees with stand-alone value that are not dependent on future performance under these agreements are recognized as revenue when received, and are deferred if we have continuing performance obligations and have no objective and reliable evidence of the fair value of those obligations. We recognize non-refundable upfront technology access fees under agreements in which we have a continuing performance obligation ratably, on a straight-line basis, over the period during which we are obligated to provide services. Cost reimbursements for research and development spending are recognized when the related costs are incurred and when collectability is reasonably assured. Payments received related to substantive, performance-based “at-risk” milestones are recognized as revenue upon achievement of the milestone event specified in the underlying contracts, which represent the culmination of the earnings process. Amounts received in advance are recorded as deferred revenue until the technology is transferred, costs are incurred, or a milestone is reached.

• Technology license agreements typically consist of non-refundable upfront license fees, annual minimum access fees, development and/or regulatory milestone payments and/or royalty payments. Non-refundable upfront license fees and annual minimum payments received with separable stand-alone values are recognized when the technology is transferred or accessed, provided that the technology transferred or accessed is not dependent on the outcome of the continuing research and development efforts. Otherwise, revenue is recognized over the period of our continuing involvement, and, in the case of development and/or regulatory milestone payments, when the applicable event triggering such a payment has occurred.

• Government grants, which support our research efforts on specific projects, generally provide for reimbursement of approved costs as defined in the terms of grant awards. Grant revenue is recognized when associated project costs are incurred.

Research and Development Expenses

Research and development expenses are composed of both internal and external costs. Internal costs include salaries and employment-related expenses of scientific personnel and direct project costs. External research and development expenses consist primarily of costs associated with clinical and non-clinical development of AV-101, our prodrug candidate entering late-stage clinical development for Major Depressive Disorder, sponsored stem cell research and development costs, and costs related to the application and prosecution of patents related to our stem cell technology platform and AV-101. All such costs are charged to expense as incurred.

Stock-Based Compensation

We recognize compensation cost for all stock-based awards to employees based on the grant date fair value of the award. We record non-cash, stock-based compensation expense over the period during which the employee is required to perform services in exchange for the award, which generally represents the scheduled vesting period. We have granted no restricted stock awards nor do we have any awards with market or performance conditions. For equity awards to non-employees, we re-measure the fair value of the awards as they vest and the resulting value is recognized as an expense during the period over which the services are performed.

Income Taxes

We account for income taxes using the asset and liability approach for financial reporting purposes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established, when necessary, to reduce the deferred tax assets to an amount expected to be realized.

Concentrations of Credit Risk

Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents. Our investment policies limit any such investments to short-term, low-risk investments. We deposit cash and cash equivalents with quality financial institutions and are insured to the maximum of federal limitations. Balances in these accounts may exceed federally insured limits at times.

Warrant Liability

We have issued to Platinum Long Term Growth VII, LLC, our largest investor (Platinum), warrants to purchase a substantial number of unregistered shares of our common stock and, subject to Platinum’s exercise of its rights to exchange shares of our Series A Preferred Stock that it holds, we are obligated to issue to Platinum an additional warrant to purchase unregistered shares of common stock (collectively, the Platinum Warrants). The Platinum Warrants contain an exercise price adjustment feature that will lower the exercise price of the warrants in the event we subsequently issue equity instruments at a price lower than the exercise price of the Platinum Warrants. We account for the Platinum Warrants as non-cash liabilities and estimate their fair value as described in Note 4, Fair Value Measurements, Note 8, Convertible Promissory Notes and Other Notes Payable, and Note 9, Capital Stock. We compute the fair value of the warrant liability at each reporting period and record the change in the fair value as non-cash expense or non-cash income. The key component in determining the fair value of the Platinum Warrants and the related liability is the market price of our common stock, which is subject to significant fluctuation and is not under our control. The resulting change in the fair value of the warrant liability on our net loss is therefore also subject to significant fluctuation and will continue to be so until all of the Platinum Warrants are issued and exercised, amended or expire. Assuming all other fair value inputs remain generally constant, we will record an increase in the warrant liability and non-cash losses when our stock price increases and a decrease in the warrant liability and non-cash gains when our stock price decreases. As described in Note 16, Subsequent Events, during May 2015, we entered into an agreement with Platinum pursuant to which Platinum agreed to amend the Platinum Warrants to fix the exercise price thereof at $7.00 per share and eliminate the exercise price reset features and fix the number of shares of our common stock issuable thereunder. This amendment will result in the elimination of the warrant liability with respect to the Platinum Warrants during the first quarter of our fiscal year ended March 31, 2016.

Comprehensive Loss

We have no components of other comprehensive loss other than net loss, and accordingly our comprehensive loss is equivalent to our net loss for the periods presented.

Loss per Common Share

Basic income (loss) per share of common stock excludes the effect of dilution and is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period. Diluted income (loss) per share of common stock reflects the potential dilution that could occur if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock. In calculating diluted net income (loss) per share, we adjust the numerator for the change in the fair value of the warrant liability attributable to the outstanding Platinum Warrants, only if dilutive, and increase the denominator to include the number of potentially dilutive common shares assumed to be outstanding during the period using the treasury stock method. As a result of our net loss for both periods presented, potentially dilutive securities were excluded from the computation of diluted loss per share, as their effect would be antidilutive.

Basic and diluted net loss attributable to common stockholders per share was computed as follows:

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606).which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition., The amendment in this ASU provides guidance on revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The core principle of this update provides guidance to identify the performance obligations under the contract(s) with a customer and how to allocate the transaction price to the performance obligations in the contract. It further provides guidance to recognize revenue when (or as) the entity satisfies a performance obligation. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2016 (the first quarter of our fiscal year ending March 31, 2018). In April 2015, the FASB proposed to defer for one year the effective date of the new revenue standard, with an option that would permit companies to adopt the standard as early as the original effective date. Early adoption prior to the original effective date is not permitted. We have not determined the potential effects of adopting this ASU on our consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation. The amendments in this ASU remove all incremental financial reporting requirements for development stage entities. Among other changes, this ASU no longer requires development stage entities to present inception-to-date information about income statement line items, cash flows, and equity transactions. The presentation and disclosure requirements in Topic 915 will no longer be required for the first annual period beginning after December 15, 2014, with early adoption permitted. We have adopted ASU 2014-10 effective with our fiscal year beginning April 1, 2014 and, accordingly, have eliminated inception-to-date information in the accompanying Consolidated Statements of Operations and Comprehensive Loss and Consolidated Statements of Cash Flows.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The amendments in this ASU define when and how an entity is required to disclose going concern uncertainties, which must be evaluated each interim and annual period. Specifically, the ASU requires management to determine whether substantial doubt exists regarding the entity’s going concern presumption. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable (as defined under ASC 450, Contingencies) that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued or are available to be issued. If substantial doubt exists, certain disclosures are required, the extent of which depends on an evaluation of management’s plans (if any) to mitigate the going concern uncertainty. This evaluation should include consideration of conditions and events that are either known or are reasonably knowable at the date the financial statements are issued or are available to be issued, as well as whether it is probable that management's plans to address the substantial doubt will be implemented and, if so, whether it is probable that the plans will alleviate the substantial doubt. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim and annual periods thereafter. Early application is permitted. In their opinion on our audited financial statements for our fiscal year ended March 31, 2015, our auditors indicated that there was substantial doubt about our ability to continue as a going concern. Although we have not yet adopted ASU 2014-15, we have indicated in Note 2, Basis of Presentation and Going Concern, steps we have taken to eliminate certain of our indebtedness and raise additional financing that is expected to permit us to continue our operations for at least one year. Upon our adoption of ASU 2014-15, assuming conditions at such time indicate there is substantial doubt about our ability to continue as a going concern, or that such doubt has been alleviated, we will conform our disclosure to comply with the guidance contained in ASU 2014-15.

Fair Value Measurements

Fair Value Measurements

4. Fair Value Measurements

We follow the principles of fair value accounting as they relate to its financial assets and financial liabilities. Fair value is defined as the estimated exit price received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, rather than an entry price that represents the purchase price of an asset or liability. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on several factors, including the instrument’s complexity. The required fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels is described as follows:

•

Level 1 — Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•

Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3 — Unobservable inputs (i.e., inputs that reflect the reporting entity’s own assumptions about the assumptions that market participants would use in estimating the fair value of an asset or liability) are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Where quoted prices are available in an active market, securities are classified as Level 1 of the valuation hierarchy. If quoted market prices are not available for the specific financial instrument, then the Company estimates fair value by using pricing models, quoted prices of financial instruments with similar characteristics or discounted cash flows. In certain cases where there is limited activity or less transparency around inputs to valuation, financial assets or liabilities are classified as Level 3 within the valuation hierarchy.

We do not use derivative instruments for hedging of market risks or for trading or speculative purposes. In conjunction with the Senior Secured Convertible Promissory Notes issued to Platinum between October 2012 and July 2013 and the related Platinum Warrants (see Note 8, Convertible Promissory Notes and Other Notes Payable), and the contingently issuable Series A Exchange Warrant (see Note 9, Capital Stock), we determined that the warrants included certain exercise price adjustment features requiring the warrants to be treated as liabilities, which were recorded at their issuance-date estimated fair values. We determined the fair value of the warrant liabilities using a Monte Carlo simulation model with Level 3 inputs. Inputs used to determine fair value include the remaining contractual term of the notes, risk-free interest rates, expected volatility of the price of the underlying common stock, and the probability of a financing transaction that would trigger a reset in the warrant exercise price, and, in the case of the Series A Exchange Warrant, the probability of Platinum’s exchange of the shares of Series A Preferred it holds into shares of common stock. Changes in the fair value of these warrant liabilities have been recognized as non-cash income or expense in the Consolidated Statements of Operations and Comprehensive Loss for the fiscal years ended March 31, 2015 and 2014.

The fair value hierarchy for liabilities measured at fair value on a recurring basis is as follows:

			Fair Value Measurements at Reporting Date Using
	Total Carrying		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
	Value		(Level 1)		(Level 2)		(Level 3)
March 31, 2015:
Warrant liability	$	3,008,500	$	-	$	-	$	3,008,500
March 31, 2014:
Warrant liability	$	2,973,900	$	-	$	-	$	2,973,900

During the fiscal years ended March 31, 2015 and 2014, there were no significant changes to the valuation models used for purposes of determining the fair value of the Level 3 warrant liability.

The changes in Level 3 liabilities measured at fair value on a recurring basis are as follows:

	Fair Value Measurements Using Significant Unobservable Inputs
	(Level 3)
	Warrant Liability

Balance at March 31, 2013	$	6,394,000

Recognition of warrant liability upon issuance of Senior Secured Convertible
Promissory Note and warrant to Platinum on July 26, 2013		146,800
Mark to market gain included in net loss		(3,566,900	)

Balance at March 31, 2014		2,973,900
Mark to market loss included in net loss		34,600

Balance at March 31, 2015	$	3,008,500

As described in Note 16, Subsequent Events, during May 2015, we entered into an agreement with Platinum pursuant to which Platinum agreed to amend the Platinum Warrants and the Series A Exchange Warrant to fix the exercise price thereof at $7.00 per share and eliminate the exercise price reset features and fix the number of shares of our common stock issuable thereunder. This amendment will result in the elimination of the warrant liability with respect to these warrants during the first quarter of our fiscal year ended March 31, 2016.

No assets or other liabilities were measured on a recurring basis at fair value at March 31, 2015 or 2014.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Significant changes in our convertible promissory notes and other promissory notes during the fiscal years ended March 31, 2015 and 2014 are described below:

10% Convertible Notes Issued in Connection with 2014 Unit Private Placement

As described more completely in the section entitled 2014 Unit Private Placement in Note 9, Capital Stock, between late March 2014 and March 31, 2015, we issued to accredited investors 10% convertible notes (the 2014Unit Notes) in the aggregate face amount of $3,113,500, including an aggregate face amount of $1,250,000 of such notes issued to Platinum and 2014 Unit Notes in the aggregate principal amount of $50,000 issued prior to March 31, 2014, in connection with our private placement offering of Units. (See Note 16, Subsequent Events, for information regarding additional notes issued in connection with the 2014 Unit Private Placement after March 31, 2015.) The 2014 Unit Notes mature on March 31, 2015 (Maturity) and the outstanding principal of the 2014 Unit Notes and their related accrued interest (the Outstanding Balance) is convertible into shares of our common stock at a conversion price of $10.00 per share at or prior to Maturity, at the option of the investor. In addition, upon our consummation of either (i) an equity or equity-based public financing registered with the SEC, or (ii) an equity or equity-based private placement, or series of private placements, not registered with the SEC, in either case resulting in gross cash proceeds to us of at least $10.0 million prior to Maturity (a Qualified Financing), the Outstanding Balance of the 2014 Unit Notes will automatically convert into securities substantially similar to those sold in the Qualified Financing, based on the following formula: (the Outstanding Balance as of the closing of the Qualified Financing) x 1.25 / (the per security price of the securities sold in the Qualified Financing). Under certain circumstances, the holders of the 2014 Unit Notes may request payment in cash in lieu of automatic conversion into the securities of the Qualified Financing. See Note 16, Subsequent Events, regarding the conversion of the Outstanding Balance of all of the 2014 Unit Notes pursuant to a private placement financing in May 2015.

We allocated the proceeds from the sale of the units to the 2014 Unit Notes, the common stock and the warrants comprising the units based on the relative fair value of the individual securities in the unit on the date of the unit sale. Based on the short-duration of the 2014 Unit Notes and their other terms, we determined that the fair value of the 2014 Unit Notes at the date of issuance was equal to their face value. Accordingly, we recorded an initial discount attributable to each 2014 Unit Note for an amount representing the difference between the face value of the 2014 Unit Note and its allocated relative value. Additionally, the 2014 Unit Notes contain an embedded conversion feature, most of which had an intrinsic value at the issuance date, which value we treated as an additional discount attributable to such 2014 Unit Notes, subject to limitations on the absolute amount of discount attributable to each 2014 Unit Note. We recorded a corresponding credit to additional paid-in capital, an equity account, attributable to the beneficial conversion feature. We amortize the aggregate discount attributable to the 2014 Unit Notes using the effective interest method over the respective term of each 2014 Unit Note. Because the discount on a 2014 Unit Note may be as great as 99% of its initial face value, and because we must amortize such discount over the period from issuance to maturity, which has generally been less than one year, or in the case of such notes issued after December 31, 2014, less than one calendar quarter, the calculated effective interest rate may be very high. Based on the amounts of their respective discounts and the term between issuance and maturity, the effective interest rates attributable to the 2014 Unit Notes range from approximately 38% to over 10,000%, with the weighted average effective interest rate in excess of 3,000%. During November 2014, we repaid the $10,000 face amount of a 2014 Unit Note issued in October 2014.

Senior Secured Convertible Promissory Notes issued to Platinum

In July and August 2012, we issued to Platinum senior secured convertible promissory notes in the aggregate principal amount of $1,250,000. Each note accrued interest at the rate of 10% per annum and was due and payable on July 2, 2015. The notes were each mandatorily convertible into securities that we might have issued in an equity, equity-based, or debt financing, or series of financings, subsequent to the issuance of the notes resulting in gross proceeds to us of at least $3,000,000, excluding any additional investment by Platinum.

On October 11, 2012, we entered into a Note Exchange and Purchase Agreement (NEPA Agreement) with Platinum in which the senior secured notes issued in July 2012 and August 2012 and the related accrued interest, were consolidated into and exchanged for a single senior secured convertible note in the amount of $1,272,577 (the Exchange Note) and Platinum agreed to purchase four additional 10% senior secured convertible promissory notes in the aggregate principal amount of $2.0 million (the Investment Notes), issuable over four separate $500,000 tranches between October 2012 and December 2012. The NEPA Agreement was subsequently amended as to timing of subsequent note purchases, but between October 2012 and March 2013, we issued and Platinum purchased an aggregate of $2.0 million of Investment Notes. We also entered into a Security Agreement with Platinum to secure repayment of all obligations due and payable under the terms of the Exchange Note and the Investment Notes.

The Exchange Note and each Investment Note (together, SeniorNotes) accrue interest at a rate of 10% per annum and, subject to certain limitations and exceptions set forth in the Senior Notes, unless voluntarily converted earlier by Platinum, will be due and payable in restricted shares of our common stock on October 11, 2015, or three years following the date of issuance, as determined by the terms of the Investment Notes. Subject to certain terms and conditions, at maturity, all principal and accrued interest under the Senior Notes will be repaid through our issuance of restricted shares of our common stock to Platinum. Subject to certain potential adjustments set forth in the Senior Notes, the number of restricted shares of common stock issuable as payment in full for each of the Notes at maturity will be calculated by dividing the outstanding Senior Note balance plus accrued interest by $10.00 per share. Prior to maturity, the outstanding principal and any accrued interest on the Exchange Note and each of the Investment Notes is convertible, in whole or in part, at Platinum’s option into shares of our common stock at a conversion price of $10.00 per share, subject to certain adjustments. Refer to Note 16, Subsequent Events, for information regarding the conversion of the Senior Notes and accrued interest into shares of Series B Preferred stock during May 2015.

As additional consideration for the purchase of the Investment Notes, we issued to Platinum warrants to purchase an aggregate of 100,000 shares of our common stock, issuable in separate tranches together with each Investment Note. We issued four warrants to Platinum between October 2012 and March 2013 (each an Investment Warrant) to purchase an aggregate of 100,000 shares of our restricted common stock. Additionally, we issued Platinum a warrant to purchase 63,629 shares of our common stock in connection with the issuance of the Exchange Note (Exchange Warrant). At issuance, the Exchange Warrant and each Investment Warrant had a term of five-years and an exercise price of $30.00 per share, subject to certain adjustments. Effective on May 24, 2013, we entered into an Amendment and Waiver agreement with Platinum pursuant to which we agreed to reduce the exercise price of the Exchange Warrant and the Investment Warrants from $30.00 per share to $10.00 per share in consideration for Platinum’s agreement to waive its rights for any increase in the number of shares of common stock issuable under the adjustment provisions of the Exchange Warrant and the Investment Warrants that would otherwise occur from certain issuances and prospective issuances of our securities, including issuances pursuant to the prospective Autilion Financing and other private placement transactions, at a price of less than $30.00 per share.

On July 26, 2013, we issued an additional senior secured convertible promissory note in the principal amount of $250,000 to Platinum (July 2013 Note). The July 2013 Note matures on July 26, 2016 and is otherwise in the same form as the earlier Investment Notes, bearing interest at 10% per annum and being payable in restricted shares of our common stock and convertible, in whole or in part, at Platinum’s option into shares of our restricted common stock at a conversion price of $10.00 per share, subject to certain adjustments. The conversion feature in the July 2013 Note constituted a beneficial conversion feature at the date of issuance. As additional consideration for the purchase of the July 2013 Note, we also issued to Platinum a five-year warrant to purchase 12,500 shares of our restricted common stock at an exercise price of $10.00 per share (July 2013 Warrant). The fair value of the July 2013 Warrant was estimated to be $11.74 per share, or $146,800, at its issuance date using a Monte Carlo simulation model and the following assumptions: market price of common stock: $15.00 per share; exercise price: $10.00 per share; risk-free interest rate: 1.36%; volatility: 96.9%; term: 5.0 years; and dividend rate 0.0%. We recorded the fair value of the July 2013 Warrant at the date of issuance as a liability and as a corresponding discount to the July 2013 Note.

The conversion option embedded in the July 2013 Note resulted in a beneficial conversion feature having intrinsic value of $100,700 at issuance. We recorded the issuance-date intrinsic value of the beneficial conversion feature as an additional component of the discount attributable to the July 2013 Note. The aggregate discount attributable to the July 2013 Note was $247,500, resulting in an issuance date carrying value of $2,500. As with the Investment Notes, we amortize the aggregate discount attributable to each note using the effective interest method over the respective term of each note. Considering the amount of the discount and the term of the note, the effective interest rate of the July 2013 Note was determined to be 159%.

Subject to limited exceptions, the Exchange Warrant, each of the Investment Warrants and the July 2013 Warrant include certain exercise price reset and anti-dilution protection features in the event that we issue other securities during the five-year term of the warrants at a price less than $10.00 per share, as amended for the Exchange Warrant and the Investment Warrants. As a result of these provisions, the Exchange Warrant, the Investment Warrants and the July 2013 Warrant do not meet the criteria set forth in ASC 815, Derivatives and Hedging, to be treated as equity instruments. Consequently, we initially recorded the Exchange Warrant, each of the Investment Warrants and the July 2013 Warrant as liabilities at their fair value and adjust them at the end of each reporting period. (See Note 4, Fair Value Measurements.)

Note Conversion and Warrant Amendment Agreement with Platinum

On July 18, 2014, we entered into an Amended and Restated Note Conversion Agreement and Warrant Amendment with Platinum (Amendment), pursuant to which Platinum agreed to convert into our unregistered equity securities all Senior Secured Convertible Promissory Notes (Senior Notes) held by Platinum, including accrued but unpaid interest thereon (Outstanding Balance), in the aggregate amount of approximately $4.2 million at the date of the agreement, upon our consummation on or before August 31, 2014 (Closing Date), of either (i) a private equity financing resulting in aggregate gross proceeds of at least $36.0 million (Private Financing), or (ii) a public offering of our equity securities registered with the SEC resulting in gross proceeds of at least $10.0 million (Public Offering) (the Private Financing and Public Offering are referred to in this discussion as a Platinum Qualified Financing). In August and September 2014, we amended the Amendment to extend the Closing Date until October 31, 2014. Upon consummation of a Private Financing, the Senior Notes would have converted into that number of unregistered shares of our common stock equal to the Outstanding Balance on the Closing Date, divided by $10.00 per share. Upon consummation of a Public Offering, the Senior Notes would have converted into shares of a new class of Series B Convertible Preferred Stock (Series B Preferred) at the lower of $10.00 per share or the lowest per-share price in the Public Offering.

Additionally, pursuant to the terms and conditions of the Amendment, in the event we had consummated a Platinum Qualified Financing on or before the Closing Date, the exercise price of the Platinum Warrants we have issued to Platinum in connection with the Senior Notes, and warrants that we may still issue pursuant to the Note Exchange and Purchase Agreement between us and Platinum, dated October 11, 2012 (NEPA), if any, would have been fixed at the lower of $10.00 per share or the purchase price of common stock sold in the Platinum Qualified Financing. Finally, the anti-dilutive provisions contained in the Platinum Warrants, other than typical adjustments for stock splits, combinations and dividends, would have been terminated as of the Closing Date.

Through March 31, 2015, we did not request Platinum to extend the Closing Date of the Amendment or enter into any other agreement with Platinum regarding the conversion of the Senior Notes, fixing the exercise price of the Platinum Warrants or terminating the anti-dilution provisions of the Platinum Warrants. Refer to Note 16, Subsequent Events, regarding the conversion of the Senior Notes and accrued interest into shares of Series B Preferred stock and modifications made to the exercise price and anti-dilution provisions of the Platinum Warrants in May 2015.

At the execution of the Amendment, we determined that the Amendment resulted in a modification of the Senior Notes that should be accounted for as an extinguishment of debt. Considering, among other factors, the cash flows and conversion features of the Senior Notes as modified by the Amendment, market interest rates for debt of similar quality and the relative probabilities of conversion of the Senior Notes into either shares of our common stock or Series B Preferred upon consummation of a Qualified Financing, we determined that the fair values of the Senior Notes at July 18, 2014, aggregating $6,475,000, represented a substantial premium over their aggregate $4,138,700 face values plus accrued interest. In accordance with the provisions of ASC 470-20, Debt with Conversion and Other Options, we recognized the premium in excess of the face value and accrued interest, $2,336,300, as a non-cash component of loss on extinguishment of debt in the accompanying Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income with a credit to additional paid-in capital, an equity account. Consequently, we recorded the liability for the Senior Notes at their face values plus accrued interest. We recognized the difference between the pre-modification carrying values of the notes and their face values, an aggregate of $1,983,700, as an additional non-cash charge to loss on extinguishment of debt in the accompanying Condensed Consolidated Statement of Operations and Comprehensive (Loss) Income. Certain of the Senior Notes contained a beneficial conversion feature at the time they were originally issued. We have accounted for the repurchase of the beneficial conversion feature at the time of the modification, an aggregate of $2,716,600, as a reduction to the loss on extinguishment of debt in the accompanying Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income, with a corresponding reduction to additional paid-in capital. The net amount of the loss on extinguishment of debt related to the amendment of the Senior Notes recognized in the accompanying Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income for the nine months ended December 31, 2014 is $1,603,400.

At the date of its issuance, we recorded the fair value of the Exchange Warrant as a liability and as a corresponding charge to loss on early extinguishment of debt. We recorded the fair value of each Investment Warrant and the July 2013 Warrant at the date of issuance as a liability and as a corresponding discount to the related note. Subject to limitations of the absolute amount of discount attributable to each Investment Note and the July 2013 Note, we treated the issuance-date intrinsic value of the beneficial conversion feature embedded in each Investment Note and the July 2013 Note as an additional component of the discount attributable to such note and recorded a corresponding discount attributable to the beneficial conversion feature for each note. Prior to the Amendment, at which time the remaining unamortized discount was written off in our determination of the loss on extinguishment of debt, we had amortized the aggregate discount attributable to each of the Investment Notes and the July 2013 Note using the effective interest method over the respective term of each note. The effective interest rate of the Exchange Note was 10.0% at inception and the effective interest rate at inception for each of the Investment Notes and the July 2013 Note was 159.1% .

We re-measure the fair value of the Exchange Warrant, the Investment Warrants and the July 2013 Warrant (collectively, the Platinum Warrants) at each quarterly reporting period. As of March 31, 2015 and 2014, we measured the fair value of such warrants at an aggregate of $810,100 and $915,300, respectively. The aggregate decrease in fair value between March 31, 2014 and March 31, 2015 of $105,200 and the aggregate decrease in fair value between March 31, 2013 and March 31, 2014 of $1,219,500 is reflected in the Change in Warrant Liability in the accompanying Consolidated Statement of Operations and Comprehensive Income for the years ended March 31, 2015 and 2014, respectively.

10% Convertible Notes Issued in Connection with 2013 Unit Private Placement

As described more completely in the section entitled 2013 Unit Private Placement in Note 9, Capital Stock, between August 2013 and March 2014, we issued to accredited investors 10% convertible promissory notes (the “2013Unit Notes”) in an aggregate face amount of $1,007,500 in connection with our private placement of Units. The maturity date of the 2013 Unit Notes was July 30, 2014 and each 2013 Unit Note and its related accrued interest was convertible into shares of our common stock at a fixed conversion price of $10.00 per share at or prior to maturity, at the option of the accredited investor.

We allocated the proceeds from the sale of the units to the 2013 Unit Notes, the common stock and the warrants comprising the Units based on the relative fair value of the individual securities in each Unit on the dates of the Unit sales. Based on the short-duration of the 2013 Unit Notes and their other terms, we determined that the fair value of the 2013 Unit Notes at the date of issuance was equal to their face value. Accordingly, we recorded an initial discount attributable to each 2013 Unit Note for an amount representing the difference between the face value of the 2013 Unit Note and its relative value. Additionally, the 2013 Unit Notes contain an embedded conversion feature, certain of which had an intrinsic value at the issuance date, which value we treated as an additional discount attributable to such 2013 Unit Notes, subject to limitations on the absolute amount of discount attributable to each 2013 Unit Note. We recorded a corresponding credit to additional paid-in capital, an equity account in the Consolidated Balance Sheet, attributable to the beneficial conversion feature. We amortized the aggregate discount attributable to each of the 2013 Unit Notes using the effective interest method over the respective term of each 2013 Unit Note. Based on their respective discounts, the weighted average effective interest rate attributable to the 2013 Unit Notes at issuance was 464.1%.

Amendment of 2013 Unit Notes and Warrants

Effective May 31, 2014, we entered into note and warrant amendment agreements with substantially all holders of our 2013 Unit Notes and 2013 Unit Warrants, each of whom agreed to (i) modify certain terms of their 2013 Unit Note to conform to the corresponding terms of the 2014 Unit Notes, including an extension of the maturity date of their 2013 Unit Note from July 30, 2014 to March 31, 2015, as well as adoption of the automatic conversion and 25% conversion premium features related to consummation of a Qualified Financing, as described previously (Amended 2013 Unit Notes), and (ii) modify certain terms of their 2013 Unit Warrants, including the exercise price and expiration date, to conform to the corresponding terms of the 2014 Unit Warrants (Amended 2013 Unit Warrants). Holders of 2013 Unit Notes having an aggregate initial face amount of $895,000 agreed to such amendments. The maturity date of 2013 Unit Notes payable to holders who did not agree to amend their 2013 Unit Note and 2013 Unit Warrant remained July 30, 2014 and the $20.00 per share exercise price and July 30, 2016 expiration date of the 2013 Unit Warrants held by such holders remains unchanged. Between April 1, 2014 and August 15, 2014, we repaid 2013 Unit Notes having an initial face value of $ 112,500 and since the later date, no un-amended 2013 Unit Notes remain outstanding.

We determined that the modification of the 2013 Unit Notes and the 2013 Unit Warrants should be accounted for as an extinguishment of debt. Considering the cash flows and the non-contingent and contingent beneficial conversion features of the Amended 2013 Notes and other factors, including market interest rates for unsecured debt of similar quality and the probability of their conversion to securities in a Qualified Financing, we determined that the fair values of the Amended 2013 Unit Notes, aggregating $1,394,000, represented a substantial premium over their aggregate $943,400 face values. In accordance with the provisions of ASC 470-20, Debt with Conversion and Other Options, we recognized the premium in excess of the face value, $450,600, as a credit to additional paid-in capital, an equity account. Consequently, we recorded the liability for the Amended 2013 Unit Notes at their face values. We recognized the difference between the pre-modification carrying values of the notes and their fair values, an aggregate of $867,500, as a non-cash charge to loss on extinguishment of debt in the accompanying Condensed Consolidated Statement of Operations and Comprehensive Loss. As described in greater detail in Note 9, Capital Stock, we determined the incremental fair value of the Amended 2013 Unit Warrants, which are treated as equity instruments, to be $272,900. We recognized this incremental fair value as an additional component of loss on extinguishment of debt in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss and as a credit to additional paid-in capital. Certain of the 2013 Unit Notes contained a beneficial conversion feature when they were originally issued. We have accounted for the repurchase of the beneficial conversion feature at the time of the modification, an aggregate of $614,200, as a reduction to the loss on extinguishment of debt in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss, with a corresponding reduction to additional paid-in capital. The net amount of the loss on extinguishment of debt related to the Amended 2013 Unit Notes and Amended 2013 Unit Warrants recognized in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss is $526,200. Since the Amended 2013 Unit Notes have the same features and maturity as the 2014 Unit Notes, the two sets of notes are aggregated in the summary table above.

Issuance of Securities in Satisfaction of Technology License and Maintenance Fees and Patent Expenses

In April 2014, we entered into an agreement with Icahn School of Medicine at Mount Sinai (Icahn School), one of our long-term stem cell technology licensors, pursuant to which we issued (i) a 10% promissory note in the face amount of $300,000 due on the earlier of December 31, 2014, or the completion of a qualified financing, as defined, (ii) 15,000 restricted shares of our common stock and (iii) a warrant exercisable through March 31, 2019 to purchase 15,000 restricted shares of our common stock at an exercise price of $10.00 per share to Icahn School in satisfaction of $288,400 of stem cell technology license maintenance fees and reimbursable patent prosecution costs (the Agreement). Based on the short-duration of the note, its interest rate and other terms, we determined that the fair value of the note at the date of issuance was equal to its face value. We determined the fair value of stock to be $141,000, based on the $9.40 per share quoted market price of our common stock on the date of the agreement. We calculated the fair value of the warrant to be $5.95 per share, or $89,200, using the Black Scholes Option Pricing Model and the following assumptions: market price per share: $9.40; exercise price per share: $10.00; risk-free interest rate: 1.59%; contractual term: 5.0 years; volatility: 80.3%; expected dividend rate: 0%. We recognized a loss on extinguishment of debt in the amount of $241,800 related to this settlement in the accompanying Statement of Operations and Comprehensive Loss. Under the terms of the Agreement, an additional $35,800 of license maintenance fees and reimbursable patent prosecution costs was added to the principal amount of the promissory note through December 31, 2014. We made a payment of $10,000 on the note in January 2015 and it remained outstanding at March 31, 2015.

Notes Payable to Morrison & Foerster

On May 5, 2011, we amended a previously outstanding note (the Original Note) issued to Morrison & Foerster LLP (Morrison & Foerster), then our general corporate and intellectual property counsel, in payment of legal services (the Amended Note). Under the terms of Amended Note, the principal balance of the Original Note was increased to $2,200,000, interest accrued at the rate of 7.5% per annum, and we were required to make certain payments to Morrison & Foerster.

On August 31, 2012, we restructured the Amended Note (the Restructuring Agreement). Pursuant to the Restructuring Agreement, we issued to Morrison & Foerster two new unsecured promissory notes to replace the Amended Note, one in the principal amount of $1,000,000 (Replacement Note A) and the other in the principal amount of $1,379,400 (Replacement Note B) (together, the Replacement Notes); amended an outstanding warrant to purchase restricted shares of our common stock (the Amended M&F Warrant); and issued a new warrant exercisable at $20.00 per share through September 15, 2017 to purchase restricted shares of our common stock (the New M&F Warrant). Under the terms of the Restructuring Agreement, the Amended Note was cancelled and all of our past due payment obligations under the Amended Note were satisfied. Pursuant to the terms of the Amended Note, we made a payment of $155,000 to Morrison & Foerster on August 31, 2012 and issued the Replacement Notes, each dated as of August 31, 2012. Both Replacement Notes accrue interest at the rate of 7.5% per annum and are due and payable on March 31, 2016. Replacement Note A required monthly payments of $15,000 per month through March 31, 2013, and requires $25,000 per month thereafter until maturity. Between May 2013 and March 31, 2015, we have made no payments on Replacement Note A. In accordance with the terms of the Replacement Notes, the applicable penalty interest rate of 10.0% per annum has become effective and we have accrued interest on the Replacement Notes at that rate since May 2013. Payment of the principal and interest on Replacement Note B will be made solely in restricted shares of our common stock pursuant to Morrison & Foerster’s cancellation from time to time of all or a portion of the principal and interest balance due on Replacement Note B in connection with its concurrent exercise of the New M&F Warrant, at an exercise price of $20.00 per share; provided, however, that Morrison & Foerster shall have the option to require payment of Replacement Note B in cash upon the occurrence of a change in control of the Company or an event of default, and only in such circumstances. As indicated in Note 16, Subsequent Events, in May 2015, Replacement Note B in the aggregate amount (principal and accrued but unpaid interest) of approximately $1.8 million was converted into 257,143 shares of our newly created Series B Preferred, eliminating approximately $1.8 million of our indebtedness. Additionally, Morrison & Foerster agreed to standstill and forbear until December 31, 2016 with respect to further payment requirements on Replacement Note A and accounts payable outstanding at the time of the agreement.

The New M&F Warrant is exercisable for the number of restricted shares of our common stock equal to the principal and accrued interest due under the terms of Replacement Note B divided by the warrant exercise price of $20.00 per share. At the August 31, 2012 date of grant, the New M&F Warrant was exercisable to purchase 68,969 restricted shares of our common stock. The New M&F Warrant effectively permits exercise only by the cancellation in whole or in part of our indebtedness under either of the Replacement Notes. Through March 31, 2015, we have adjusted the New M&F Warrant to increase the number of restricted shares available for purchase by 16,658 shares, based on interest accrued on Replacement Note B through that date. We have recorded the fair value of the additional warrant shares as a charge to interest expense and a corresponding credit to additional paid-in capital.

Note Payable to Cato Research Ltd.

On October 10, 2012, we issued to Cato Research Ltd (CRL) a contract research and development partner and a related party: (i) an unsecured promissory note in the initial principal amount of $1,009,000, which is payable solely in restricted shares of our common stock and which accrues interest at the rate of 7.5% per annum, compounded monthly (the CRL Note), as payment in full for all contract research and development services and regulatory advice (CRO Services) rendered by CRL to us and our affiliates through December 31, 2012 with respect to the non-clinical and clinical development of AV-101, and (ii) a five-year warrant to purchase, at a price of $20.00 per share, 50,450 restricted shares of our common stock, the amount equal to the sum of the principal amount of the CRL Note, plus all accrued interest thereon, divided by $20.00 per share (the CRL Warrant). The CRL Note is due and payable on March 31, 2016 and is payable solely by CRL's cancellation from time to time of all or a portion of the principal and interest balance due on the CRL Note in connection with its concurrent exercise of the CRL Warrant, provided, however, that CRL will have the option to require payment of the CRL Note in cash upon the occurrence of a change in control of the Company or an event of default, and only in such circumstances. Through March 31, 2015, we have adjusted the CRL Warrant to increase the number of restricted shares available for purchase by 10,241 shares, based on interest accrued on the CRL Note through that date. We have recorded the fair value of the additional shares as a charge to interest expense and a corresponding credit to additional paid-in capital.

As disclosed in Note 16, Subsequent Events, in May 2015, the CRL Note and certain accounts payable to CRL for CRO Services related to AV-101 in the aggregate amount (principal and accrued but unpaid interest, plus certain strategic adjustments) of approximately $1.9 million were converted into 278,006 shares of our Series B Preferred, eliminating approximately $1.9 million of our indebtedness.

Note Payable to Cato Holding Company

On October 10, 2012, we exchanged a previously outstanding note issued to Cato Holding Company (CHC) for a new unsecured promissory note in the principal amount of $310,400 (the 2012 CHC Note) and a five-year warrant to purchase 12,500 restricted shares of the Company’s common stock at a price of $30.00 per share (the CHC Warrant). The 2012 CHC Note accrues interest at a rate of 7.5% per annum and is due and payable in monthly installments of $10,000, beginning November 1, 2012 and continuing until the outstanding balance is paid in full. Between December 2012 and March 31, 2015, we have made no payments on the 2012 CHC Note.

As disclosed in Note 16, Subsequent Events, in May 2015, the 2012 CHC Note in the aggregate amount (principal and accrued but unpaid interest) of approximately $354,000 was converted into 50,565 shares of our Series B Preferred, eliminating approximately $354,000 of our indebtedness.

Note Payable to University Health Network

On October 10, 2012, we issued to the University Health Network (UHN): (i) an unsecured promissory note in the principal amount of $549,500, which is payable solely in restricted shares of our common stock and which accrues interest at the rate of 7.5% per annum, as payment in full for all sponsored stem cell research and development activities by UHN and Gordon Keller, Ph.D. under the SCRA through September 30, 2012 (the UHN Note), and (ii) a five-year warrant to purchase, at a price of $20.00 per share, 27,475 restricted shares of our common stock, the amount equal to the sum of the principal amount of the UHN Note, plus all accrued interest thereon, divided by $20.00 per share (the UHN Warrant). The UHN Note is due and payable on March 31, 2016 and is payable solely by UHN's cancellation from time to time of all or a portion of the principal and interest balance due on the UHN Note in connection with its concurrent exercise of the UHN Warrant, provided, however, that UHN will have the option to require payment of the UHN Note in cash upon the occurrence of a change in control of the Company or an event of default, and only in such circumstances. Through March 31, 2015, we have adjusted the UHN Warrant to increase the number of restricted shares available for purchase by 5,095 shares, based on interest accrued on the UHN Note through that date. We have recorded the fair value of the additional shares as a charge to interest expense and a corresponding credit to additional paid-in capital.

As disclosed in Note 16, Subsequent Events, in May 2015, the UHN Note in the aggregate amount (principal and accrued but unpaid interest) of approximately $656,400 was converted into 93,775 shares of our Series B Preferred, eliminating approximately $656,400 of our indebtedness.

Beginning on January 1, 2012, we are also required to make payments equal to one percent (1%) of the net proceeds of all private or public equity financings closed during the term of the note. The note payable to McCarthy was due on June 14, 2014.

As disclosed in Note 16, Subsequent Events, in May 2015, the McCarthy note in the aggregate amount (principal and accrued but unpaid interest) of approximately $414,600 was converted into 59.230 shares of our Series B Preferred, eliminating approximately $414,600 of our indebtedness.

On August 30, 2012, we issued a promissory note in the principal amount of $60,000 and 750 restricted shares of our common stock valued at a market price of $18.80 per share to Progressive Medical Research in settlement of past due obligations for clinical research services in the amount of $79,900.

The promissory note bears interest at 7% per annum and requires payments of $1,000 per month beginning January 15, 2013 until all principal and interest is paid in full. The note requires payment in full upon the sale of all or substantially all of our assets or upon our completion of a financing transaction, or series of transactions, resulting in gross proceeds to us of at least $4.0 million in any three-month period, excluding proceeds from stock option or warrant exercises. We made no payments on this note during the fiscal year ended March 31, 2015.

On October 12, 2009, VistaGen California issued a promissory note payable to the Regents of the University of California (“UC”) with a principal balance of $90,000 in exchange for the cancellation of certain amounts payable under a research collaboration agreement (the UC Note 1)..

UC Note 2 was payable in monthly principal installments of $15,000 through May 31, 2010, with the remaining $125,000 plus all accrued and unpaid interest due on or before June 30, 2010. Between June 2010 and December 2010, VistaGen California amended UC Note 2 multiple times, ultimately resulting in a decrease in the monthly payment amount to $5,000, with payments continuing until the outstanding balance of principal and interest is paid in full. We made no payments on UC Note 2 during the fiscal year ended March 31, 2015.

Reverse Split (Stock Consolidation) of our Common Stock

As indicated in Note 2, Basis of Presentation and Going Concern, we consummated the Stock Consolidation, a 1-for-20 reverse split of our authorized, and issued and outstanding shares of common stock, effective on August 14, 2014. The par value of our common stock remained unchanged at $0.001 per share following the Stock Consolidation. The Stock Consolidation was approved by the Financial Industry Regulatory Authority (FINRA) on August 13, 2014, and became effective on the OTCQB at the opening of trading on August 14, 2014. Each reference to shares of common stock or the price per share of common stock in these financial statements is post-Stock Consolidation, and reflects the 1-for-20 adjustment as a result of the Stock Consolidation.

Series A Preferred Stock

In December 2011, our Board of Directors authorized the creation of a series of up to 500,000 shares of Series A Preferred, par value $0.001 (Series A Preferred). Each restricted share of Series A Preferred was initially convertible at the option of the holder into one-half of one restricted share of our common stock. The Series A Preferred ranks prior to the common stock for purposes of liquidation preference.

The Series A Preferred has no separate dividend rights, however, whenever the Board of Directors declares a dividend on the common stock, each holder of record of a share of Series A Preferred shall be entitled to receive an amount equal to such dividend declared on one share of common stock multiplied by the number of shares of common stock into which such share of Series A Preferred could be converted on the Record Date.

Except with respect to transactions upon which the Series A Preferred shall be entitled to vote separately as a class, the Series A Preferred has no voting rights. The restricted common stock into which the Series A Preferred is convertible shall, upon issuance, have all of the same voting rights as other issued and outstanding shares of our common stock.

In the event of the liquidation, dissolution or winding up of the affairs of the Company, after payment or provision for payment of our debts and other liabilities, the holders of Series A Preferred then outstanding shall be entitled to receive an amount per share of Series A Preferred calculated by taking the total amount available for distribution to holders of all of our outstanding common stock before deduction of any preference payments for the Series A Preferred, divided by the total of (x), all of the then outstanding shares of our common stock, plus (y) all of the shares of our common stock into which all of the outstanding shares of the Series A Preferred can be converted before any payment shall be made or any assets distributed to the holders of the common stock or any other junior stock.

At March 31, 2015 and 2014, there were 500,000 restricted shares of Series A Preferred outstanding, all issued to Platinum or its affiliates. Platinum acquired the Series A Preferred pursuant to the transactions described below. In October 2012, Platinum’s exchange rights with respect to the Series A Preferred were modified as described in the section entitled Modification of Series A Preferred Exchange Rights and Deemed Dividend, below.

December 2011 Common Stock Exchange Agreement with Platinum

On December 22, 2011, we entered into a Common Stock Exchange Agreement (the Exchange Agreement") with Platinum, pursuant to which Platinum converted 24,200 restricted shares of our common stock into 45,980 restricted shares of Series A Preferred (the Exchange). Each restricted share of Series A Preferred issued to Platinum was initially convertible into ten restricted shares of our common stock. At the time of the Exchange, we determined the fair value of the common stock subject to the Exchange to be $31.00 per share and have reflected the 24,200 restricted common shares as treasury stock on that basis in the accompanying Consolidated Balance Sheet at March 31, 2015 and 2014.

December 2011 Note and Warrant Exchange Agreement with Platinum

On December 29, 2011, we entered into a Note and Warrant Exchange Agreement with Platinum pursuant to which a promissory note in the face amount of $4,000,000 plus accrued interest and all outstanding warrants issued to Platinum to purchase an aggregate of 79,993 restricted shares of our common stock were cancelled in exchange for 391,075 restricted shares of Series A Preferred. Each share of Series A Preferred was initially convertible into one-half of one share of our common stock. We issued 231,090 restricted shares of Series A Preferred to Platinum in connection with the note cancellation based on the sum of the $4,000,000 principal balance of the note plus accrued but unpaid interest through May 11, 2011 adjusted for a 125% conversion premium, net of the $1,719,800 aggregate exercise price of the 79,993 outstanding warrants held by Platinum, and a contractual conversion basis of $35.00 per common share, all adjusted for the initial 1:10 Series A Preferred to common exchange ratio. An additional 159,985 restricted shares of Series A Preferred were issued to Platinum in connection with the warrant exercise and exchange to acquire the common shares issued upon the warrant exercise.

2012 Exchange Agreement with Platinum

On June 29, 2012, we entered into an Exchange Agreement (the 2012 Platinum Exchange Agreement) with Platinum pursuant to which we issued Platinum 62,945 restricted shares of Series A Preferred in exchange for 31,473 restricted shares of our common stock then owned by Platinum, in consideration for Platinum’s agreement to purchase from us a senior secured convertible promissory note in the face amount of $500,000. We estimated the fair value of the Series A Preferred shares tendered to Platinum under the terms of the 2012 Platinum Exchange Agreement at $736,400 ($23.40 per share on a common share equivalent basis). The common shares exchanged for shares of Series A Preferred are treated as treasury stock on that basis in the accompanying Consolidated Balance Sheet at March 31, 2015 and 2014.

Modification of Series A Preferred Exchange Right

Pursuant to the October 2012 Agreement described more completely in Note 8, Convertible Promissory Notes and Other Notes Payable, Platinum’s exchange rights in the Series A Preferred were modified such that Platinum now has the right and option to exchange the 500,000 restricted shares of our Series A Preferred that it holds for (i) a total of 750,000 restricted shares of our common stock, and (ii) a five-year warrant to purchase 350,000 restricted shares of our common stock, originally at an exercise price of $30.00 per share (Series A Exchange Warrant). The Series A Exchange Warrant, when issued, will have the same features, including exercise price and anti-dilution provisions as the Exchange Warrant and the Investment Warrants issued to Platinum between October 2012 and July 2013 (collectively, the Platinum Warrants) and accordingly, has been treated as a component of Warrant Liability in our Consolidated Balance Sheets since the effective date of the October 2012 Agreement. Effective on May 24, 2013, we entered into an Amendment and Waiver Agreement (the Amendment and Waiver) with Platinum pursuant to which we agreed to reduce the exercise price of the Platinum Warrants and the Series A Exchange Warrant from $30.00 per share to $10.00 per share in consideration for Platinum’s agreement to waive certain of its rights under the anti-dilution provisions of the Platinum Warrants and the Series A Exchange Warrant. See the section entitled Modification of Platinum Warrants, later in this note, for a more complete description of the Amendment and Waiver.

Similarly to the Platinum Warrants, we remeasure the fair value of the Series A Exchange Warrant at each quarterly reporting period and reflect the change in its fair value as a component of the Change in Warrant Liability in the Consolidated Statement of Operations. The fair value of the Series A Exchange Warrant was determined to be $2,198,400 and $2,058,600 as of March 31, 2015 and 2014, respectively, and the $139,800 increase in fair value since March 31, 2014 is reflected as a component of the Change in Warrant Liability in the accompanying Consolidated Statement of Operations and Comprehensive Loss for the fiscal year ended March 31, 2015.

Creation of Series B Preferred Stock

On July 17, 2014, our Board of Directors authorized the creation of a class of Series B Preferred Stock (Series B Preferred) to provide for the potential conversion of the Senior Secured Convertible Promissory Notes held by Platinum totaling approximately $4.3 million in principal and accrued interest at December 31, 2014 (Outstanding Balance) into Series B Preferred. At March 31, 2015, we had not yet filed a certificate of designation with the Nevada Secretary of State to amend our Articles of Incorporation to formally establish the Series B Preferred. Refer to Note 16, Subsequent Events, for information regarding the filing of a Certificate of Designation for the Series B Preferred with the Nevada Secretary of State and the issuance of Series B Preferred in May and June 2015.

2014 Unit Private Placement

Between late-March 2014 and March 31, 2015, we entered into securities purchase agreements with accredited investors, including Platinum, pursuant to which we sold units to such accredited investors in private placement transactions (2014 Units), for aggregate cash proceeds of $3,113,500, consisting of (i) 2014 Unit Notes in the aggregate face amount of $3,113,500 which are due on March 31, 2015 or automatically convertible into securities we may issue upon the consummation of a Qualified Financing, defined as (a) an equity-based public financing registered with the SEC, or (b) a private equity-based financing or series of private equity-based financings, in either case in which we receive at least $10 million in gross cash proceeds prior to March 31, 2015; (ii) an aggregate of 282,850 restricted shares of our common stock (2014 Unit Stock); and (iii) warrants exercisable through December 31, 2016 to purchase an aggregate of 282,850 restricted shares of our common stock at an exercise price of $10.00 per share (2014 Unit Warrants). We sold $1,250,000 of such Units to Platinum, issuing 2014 Unit Notes in the face amount of $1,250,000; 125,000 restricted shares of 2014 Unit Stock and 2014 Unit Warrants to purchase 125,000 shares of our common stock to Platinum. The Outstanding Balance of each 2014 Unit Notes is convertible into shares of our common stock at a conversion price of $10.00 per share at or prior to maturity, at the option of each investor. In addition, however, the Outstanding Balance is automatically convertible into securities substantially similar to those we may issue in a Qualified Financing at an amount determined by multiplying the Outstanding Balance by 1.25, and dividing the resulting number by the price per share of securities offered in the Qualified Financing. Under certain circumstances, the holders of the 2014 Unit Notes may request payment in cash in lieu of automatic conversion into the securities of the Qualified Financing. We sold $50,000 of 2014 Units prior to March 31, 2014, which Units are reflected in the figures above. See Note 16, Subsequent Events, for information regarding additional sales of 2014 Unit Notes in April and May 2015 and the conversion of the 2014 Unit Notes pursuant to a private placement financing in May 2015.

We allocated the proceeds from the sale of the 2014 Units to the various securities based on their relative fair values on the dates of the sales. As described in Note 8, Convertible PromissoryNotes and Other Notes Payable, based on the short-term nature of the Unit Notes, we determined that fair value of the 2014 Unit Notes was equal to their face value. We determined the fair value of the 2014 Unit Stock based on the quoted market price of our common stock on the date of the 2014 Unit sale. We calculated the fair value of the 2014 Unit Warrants using the Black Scholes Option Pricing Model and the weighted average assumptions indicated in the table below. The table below also presents the aggregate allocation of the 2014 Unit sales proceeds based on the relative fair values of the 2014 Unit Stock, 2014 Unit Warrants and 2014 Unit Notes as of their respective 2014 Unit sales dates.

2013 Unit Private Placement

Between August 2013 and March 2014, we entered into securities purchase agreements with accredited investors pursuant to which we sold units to such accredited investors in private placement transactions (2013 Units), for aggregate cash proceeds of $1,007,500, including $50,000 in lieu of repayment of previous advances to us made by one of our executive officers. The 2013 Units consisted of (i) 10% convertible promissory notes in the aggregate face amount of $1,007,500 maturing on July 30, 2014 (2013 Unit Notes) (ii) an aggregate 100,750 restricted shares of our common stock (2013 Unit Stock); and (iii) warrants exercisable through July 30, 2016 to purchase an aggregate of 100,750 restricted shares of our common stock at an exercise price of $20.00 per share (2013 Unit Warrants). The 2013 Unit Notes and related accrued interest were convertible into restricted shares of our common stock at a conversion price of $10.00 per share at or prior to maturity, at the option of each investor.

We allocated the proceeds from the sale of the 2013 Units to the various securities in each 2013 Unit based on their relative fair value on the dates of the sales. As described in Note 8, Convertible PromissoryNotes and Other Notes Payable, based on the short-term nature of the 2013 Unit Notes, we determined that fair value of the 2013 Unit Notes was equal to their face value. We determined the fair value of the 2013 Unit Stock based on the quoted market price of our common stock on the date of the 2013 Unit sale. We calculated the fair value of the 2013 Unit Warrants using the Black Scholes Option Pricing Model and the weighted average assumptions indicated in the table below. The table below also presents the aggregate allocation of the 2013 Unit sales proceeds based on the relative fair values of the 2013 Unit Stock, 2013 Unit Warrants and 2013 Unit Notes at the respective 2013 Unit sales date.

Amendment of 2013 Unit Notes and 2013 Unit Warrants

As indicated in Note 8, Convertible Promissory Notes and Other Notes Payable, effective May 31, 2014, we entered into note and warrant amendment agreements with substantially all holders of 2013 Unit Notes and 2013 Unit Warrants to (i) modify certain terms of their 2013 Unit Notes, including the maturity date and certain conversion features, to conform to the corresponding terms of the 2014 Unit Notes and (ii) to modify certain terms of the 2013 Unit Warrants, including the exercise price and expiration date, to conform to the corresponding terms of the 2014 Unit Warrants. Holders of 2013 Unit Notes having an aggregate initial face amount of $895,000 and warrants to purchase an aggregate of 93,250 restricted shares of our common stock agreed to the amendments.

We calculated the fair value of the modified 2013 Unit Warrants immediately before and after the modifications and determined that the fair value of the warrants increased by an aggregate of $272,900, which we treated as a component of loss on extinguishment of debt in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Loss with a corresponding credit to additional paid-in capital, an equity account. The warrants subject to the exercise price modifications were valued using the Black-Scholes Option Pricing Model and the following assumptions:

Assumption:	Pre-modification		Post-modification

Issuance of Securities in Satisfaction of Technology License and Maintenance Fees and Patent Expenses

In April 2014, we entered into an agreement with Icahn School of Medicine at Mount Sinai (Icahn School), one of our long-term stem cell technology licensors, pursuant to which we issued (i) a 10% promissory note in the face amount of $300,000 due on the earlier of December 31, 2014, or the completion of a qualified financing, as defined, (ii) 15,000 restricted shares of our common stock and (iii) a warrant exercisable through March 31, 2019 to purchase 15,000 restricted shares of our common stock at an exercise price of $10.00 per share to Icahn School in satisfaction of $288,400 of stem cell technology license maintenance fees and reimbursable patent prosecution costs (the Icahn School Agreement). Based on the short-duration of the note, its interest rate and other terms, we determined that the fair value of the note at the date of issuance was equal to its face value. We determined the fair value of stock to be $141,000, based on the $9.40 per share quoted market price of our common stock on the date of the agreement. We calculated the fair value of the warrant to be $5.95 per share, or $89,200, using the Black Scholes Option Pricing Model and the following assumptions: market price per share: $9.40; exercise price per share: $10.00; risk-free interest rate: 1.59%; contractual term: 5.0 years; volatility: 80.3%; expected dividend rate: 0%. We recognized a loss on extinguishment of debt in the amount of $241,800 related to this settlement in the accompanying Statement of Operations and Comprehensive Loss. Under the terms of the Icahn School Agreement, an additional $35,800 of license maintenance fees and reimbursable patent prosecution costs were added to the principal amount of the promissory note through March 31, 2015. The note remains outstanding at March 31, 2015.

Issuance of Common Stock to Consultants

In May 2014, we entered into a consulting agreement for strategic advisory and business development services pursuant to which we issued 10,000 restricted shares of our common stock as partial compensation for such professional services. We determined the fair value of stock to be $134,000, based on the $13.40 per share quoted market price of our common stock on the date of the agreement. Additionally, under the terms of the agreement, we paid an aggregate of $80,000 between May 2014 and December 31, 2014 as additional compensation for professional services rendered by the consultant. Effective January 12, 2015, we entered into a new consulting agreement with this consultant for similar services through December 31, 2015 pursuant to which we have issued 20,000 restricted shares of our common stock valued at $160,000, based on the $8.00 per share quoted market price of our common stock on the date of the agreement, and made cash payments of $20,000 as compensation for such professional services.

In March 2015, we entered into a consulting agreement with another consultant for additional advisory and business development services pursuant to which we issued 25,000 restricted shares of our common stock as compensation for such professional services. We determined the fair value of stock to be $175,000, based on the $7.50 per share quoted market price of our common stock on the date of the agreement.

In March 2015, we issued 16,667 shares of our common stock valued at $166,700 to our legal counsel in settlement of direct legal fees related to services provided with respect to our prospective public offering of our equity securities in the fall of 2014 and the Autilion Financing. We recognized a loss of $16,700 with respect to this settlement, which is included in Loss on Extinguishment of Debt in the accompanying Statement of Operations and Comprehensive Loss for the year ended March 31, 2015.

Warrants to Purchase Common Stock

Warrant Grants and Exercises

In January 2015, when the market price of our common stock was $8.00 per share, our Board of Directors (Board) authorized the grant of fully-vested five-year warrants to purchase an aggregate of 381,000 restricted shares of our common stock at an exercise price of $10.00 per share, including an aggregate of 340,000 such shares to company officers and independent members of the Board. The Board also granted one-year warrants to purchase 5,715 restricted shares of our common stock at an exercise price of $10.00 per share to consultants whose warrants had expired at December 31, 2014. Additionally, the Board extended by one year the expiration date of outstanding warrants to purchase 90,675 shares of our restricted common stock otherwise expiring during calendar 2015 and reduced the exercise price to $15.00 per share for such of those extended term warrants having exercise prices in excess of that amount.

We valued the new warrant grants at $1,756,900 using the Black Scholes Option Pricing Model and the following assumptions: market price per share: $8.00; exercise price per share: $10.00; risk-free interest rate: 1.45% for five-year warrants and 0.24% for one-year warrants; contractual term: 5 years or 1 year; volatility: 75.86% for five-year warrants and 69.74% for one-year warrants; expected dividend rate: 0%..

We calculated the fair value of the modified warrants immediately before and after the modifications and determined that the fair value of the warrants increased by $98,400, which is reflected in general and administrative expense in the accompanying Consolidated Statements of Operations and Comprehensive Loss for the fiscal year ended March 31, 2015. The warrants subject to the exercise price modifications and term extensions were valued using the Black-Scholes Option Pricing Model and the following assumptions:

Assumption:	Pre-modification		Post-modification
Market price per share at modification date	$	8.00	$	8.00
Exercise price per share (weighted average)	$	23.13	$	13.00
Risk-free interest rate (weighted average)		0.04%		0.31%
Contractual term in years (weighted average)		0.24		1.24
Volatility (weighted average)		69.7%		69.8%
Dividend rate		0.0%		0.0%

Weighted Average Fair Value per share	$	0.22	$	1.31

On March 19, 2014, we granted five-year warrants to purchase an aggregate of 20,750 restricted shares of our unregistered common stock at an exercise price of $10.00 per share to the independent members of our Board and certain of our officers. The warrants became exercisable for 50% of the shares on April 1, 2014, and become exercisable for an additional 25% of the shares on April 1, 2015 and 25% of the shares on April 1, 2016, provided that the warrant will become fully vested upon a change in control of the Company, as defined, or the consummation between us and a third party of a license or sale transaction involving at least one new drug rescue variant. We valued the warrants at $120,800 using the Black Scholes Option Pricing Model and the following assumptions: market price per share: $9.20; exercise price per share: $10.00; risk-free interest rate: 1.75%; contractual term: 5 years; volatility: 80.57%; expected dividend rate: 0%. We recognized stock compensation expense of $54,100 related to the grants in the fourth quarter of the fiscal year ended March 31, 2014 and $27,000 during the fiscal year ended March 31, 2015..

In October 2013, we issued new warrants to purchase an aggregate of 11,875 shares of our restricted common stock to certain former warrant holders whose warrants to purchase an equivalent number of shares of our restricted common stock at an exercise price of $30.00 per share had recently expired. We calculated the fair value of the new warrants as $0.63 per share, using the Black-Scholes Option Pricing Model and the following assumptions. market price per share: $10.00; exercise price per share: $30.00; risk-free interest rate: 0.20%; contractual term: 1.32 years; volatility: 73.5%; and expected dividend rate: 0%. We recorded the aggregate fair value of $7,400 for the new warrants in general and administrative expense in the accompanying Consolidated Statements of Operations and Comprehensive Loss for the fiscal year ended March 31, 2014.

In June 2013 and October 2013, our Chief Executive Officer partially exercised an outstanding warrant to purchase 2,500 and 500 restricted shares of the Company’s common stock, respectively, at an exercise price of $12.80 per share, and we received cash proceeds of $32,000 and $6,400, respectively, from the exercises.

Modification of Warrants Held by Platinum

As indicated earlier in this note, effective on May 24, 2013, we entered into an Amendment and Waiver Agreement (Amendment and Waiver) with Platinum pursuant to which we agreed to reduce the exercise price of the Exchange Warrant and the Investment Warrants issued to Platinum between October 2012 and March 2013 (collectively, the “Warrants”) from $30.00 per share to $10.00 per share in consideration for Platinum’s agreement to waive its rights for any increase in the number of shares of common stock issuable under the adjustment provisions of the Exchange Warrant and the Investment Warrants that would otherwise occur from (i) our sale of shares of our common stock at a price of $10.00 per share in connection with the Autilion Financing; (ii) the March 2013 grant of warrants to certain of our officers and independent directors to purchase an aggregate of 150,000 restricted shares of common stock at an exercise price of $12.80 per share; and (iii) our issuance of restricted shares of our common stock resulting in gross proceeds not to exceed $1.5 million in connection with the exercise by warrant holders, by no later than June 30, 2013, subsequently extended to July 30, 2013, of previously outstanding warrants for which we may reduce the exercise price to not less than $10.00 per share. (See “Other Warrant Modifications and Exercises” below.)

As described in Note 4, Fair Value Measurements and in Note 8, Convertible Promissory Notes and Other Notes Payable, we re-measure the fair value of the Platinum Warrants at the end of each quarterly reporting period. The fair value re-measurement at June 30, 2013 incorporated the modification of the exercise price resulting from the Amendment and Waiver and the corresponding adjustment was reflected as a component of the Warrant Liability at that date. We also re-measure at the end of each reporting period the fair value of the Series A Exchange Warrant which is contingently issuable to Platinum upon the exchange of its shares of our Series A Preferred Stock into shares of our restricted common stock. At March 31, 2015 and 2014, we determined the fair values of the Platinum Warrants and the Series A Preferred Exchange Warrant to be a weighted average of $ 5.09.and $5.40 per share, respectively, or an aggregate of $3,008,500 and 2,973,900, which amounts are reflected as Warrant Liability in the accompanying Consolidated Balance Sheets at March 31, 2015 and 2014, respectively. We determined the fair value of the warrants at March 31, 2015 and 2014 using the assumptions indicated in the table below.

	March 31,
	2015		2014

Market price of common stock	$	10.00	$	9.20
Exercise price per share	$	10.00	$	9.80 to $10.00
Risk-free interest rate	0.74% to 1.37%			1.73%
Volatility	73.3% to 75.9%			75%
Term (years)	2.5 to 5.0		3.5 to 5.0
Dividend rate		0%		0%
Probability of Series A Preferred exchange		95%		95%

Fair value per share	$	4.45 to $6.17	$	5.20 to $5.80

Other Warrant Modifications and Exercises

During the months of June and July 2013, we offered certain long-term warrant holders the opportunity to exercise warrants having an exercise price of $30.00 per share to purchase shares of our restricted common stock at a reduced exercise price of $10.00 per share through July 30, 2013. Warrant holders exercised warrants to purchase an aggregate of 26,419 restricted shares of our common stock and we received cash proceeds of $264,200. In addition, certain warrant holders exercised modified warrants to purchase 832 restricted shares of our common stock in lieu of our payment in satisfaction of amounts due for professional services in the aggregate amount of $8,300. We calculated the fair value of the warrants exercised immediately before and after the modifications and determined that the fair value of the warrants exercised decreased.

In October 2013, we modified certain outstanding warrants held by our long-term investors and consultants to purchase an aggregate of 64,639 restricted shares of our common stock to reduce the exercise price of the warrants to $10.00 per share and, for warrants scheduled to expire on December 31, 2013, extend the exercise term of the warrants until January 31, 2015, generally without modifying the exercise price. We calculated the fair value of the warrants immediately before and after the modifications and determined that the fair value of the warrants increased by $77,800, which is reflected in general and administrative expense in the accompanying Consolidated Statements of Operations and Comprehensive Loss for the fiscal year ended March 31, 2014. The warrants subject to the exercise price modifications and term extensions were valued using the Black-Scholes Option Pricing Model and the following assumptions:

Assumption:	Pre-modification		Post-modification
Market price per share at modification date	$	10.00	$	10.00
Exercise price per share (weighted average)	$	31.97	$	24.68
Risk-free interest rate (weighted average)		0.33%		0.44%
Contractual term in years (weighted average)		1.40		2.10
Volatility (weighted average)		74.4%		75.8%
Dividend rate		0.0%		0.0%

Weighted Average Fair Value per share	$	1.08	$	2.29

In December 2013, we modified additional outstanding warrants held by certain of our long-term investors, consultants, and members of management and our Board of Directors to purchase an aggregate of 63,013 restricted shares of our common stock to reduce the exercise price of the warrants to $10.00 per share and, in limited cases, extend the exercise term of the warrants. We calculated the fair value of the warrants immediately before and after the modifications and determined that the fair value of the warrants increased by $344,000, which is reflected in general and administrative expense in the accompanying Consolidated Statements of Operations and Comprehensive Loss for the fiscal year ended March 31, 2014. The warrants subject to the exercise price modifications and term extensions were valued using the Black-Scholes Option Pricing Model and the following assumptions:

Assumption:	Pre-modification		Post-modification
Market price per share at modification date	$	8.00	$	8.00
Exercise price per share (weighted average)	$	33.49	$	10.00
Risk-free interest rate (weighted average)		0.51%		0.57%
Contractual term in years (weighted average)		2.06		2.34
Volatility (weighted average)		73.6%		74.4%
Dividend rate		0.0%		0.0%

Weighted Average Fair Value per share	$	0.91	$	2.85

In making its fair value determinations for both warrant modifications and new grants using the Black Scholes Option Pricing Model, we utilize the following principles in selecting its input assumptions. The market price per share is based on the quoted market price of our common stock on the OTC Markets on the date of the modification or grant. Because of our relatively short history as a public company, we estimate stock price volatility based on the historical volatilities of a peer group of public companies over the contractual or remaining contractual term of the warrant. The contractual term of the warrant is determined based on the grant or modification date and the latest date on which the warrant can be exercised under its terms or under the terms of the discounted exercise price offer. The risk-free rate of interest is based on the quoted constant maturity rate for U.S. Treasury Bills on the date of the grant or modification for the term most closely corresponding with the contractual term or remaining term of the warrant. The dividend rate is zero as we have not paid and do not expect to pay dividends in the near future.

Warrants Outstanding

The following table summarizes outstanding warrants to purchase restricted shares of our common stock as of March 31, 2015. The weighted average exercise price of outstanding warrants at March 31, 2015 was $13.00 per share.

Exercise Price per Share		Expiration Date	Shares Subject to Purchase at March 31, 2015

$	10.00	1/31/2016 to 1/1/2020		1,064,683
$	12.80	3/3/2023		147,000

$	20.00	7/30/2016 to 9/30/2017		186,388
$	30.00	2/13/2016 to 3/4/2018		69,426
$	40.00	9/15/2017		21,250
$	60.00	2/13/2016		1,250

Note Receivable from Sale of Common Stock

In May 2011, the Company accepted a $500,000 short-term note from an investor in payment for shares of the Company’s common stock sold to the investor in a private placement transaction. On October 2, 2014 we received a cash payment of $60,000 from the maker of the note. We have considered that payment to be in full satisfaction of the outstanding principal balance of the note and related accrued interest, aggregating $194,900, at the date of the payment and recognized a loss of $134,900 on the settlement of the note, which is reflected as a component of Other expenses, net in the accompanying Statement of Operations and Comprehensive Loss.

Income Taxes

12 Months Ended

Mar. 31, 2015

Income Tax Disclosure [Abstract]

Income Taxes

11. Income Taxes

The provision for income taxes for the periods presented in the Consolidated Statements of Operations and Comprehensive Income represents minimum California franchise taxes. Income tax expense differed from the amounts computed by applying the U.S. federal income tax rate of 34% to pretax losses as a result of the following:

	Fiscal Years Ended March 31,
	2015			2014

Computed expected tax benefit		(34.0	) %		(34.0	) %
Tax effect of Warrant Liability mark to market		(0.1	) %		41.5	%
Other losses not benefitted		34.0	%		(7.5	) %
Other		0.1	%		0.1	%

Income tax expense		0.0	%		0.1	%

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets are as follows (in thousands):

	March 31,
	2015			2014
Deferred tax assets:
Net operating loss carryovers	$	23,054		$	19,733
Basis differences in fixed assets		24			37
Accruals and reserves		2,694			1,383

Total deferred tax assets		25,772			21,153

Valuation allowance		(25,772	)		(21,153	)

Net deferred tax assets	$	-		$	-

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $4,619,000 and $2,126,000 during the fiscal years ended March 31, 2015 and 2014, respectively. When realized, deferred tax assets related to employee stock options will be credited to additional paid-in capital.

As of March 31, 2015, we had U.S. federal net operating loss carryforwards of $58.7 million, which will expire in fiscal years 2020 through 2035. As of March 31, 2015, we had state net operating loss carryforwards of $53.1 million, which will expire in fiscal years 2016 through 2035.

U.S. federal and state tax laws include substantial restrictions on the utilization of net operating loss carryforwards in the event of an ownership change of a corporation. We have not performed a change in ownership analysis since our inception in 1998 and accordingly some or all of our net operating loss carryforwards may not be available to offset future taxable income, if any.

The Company files income tax returns in the U.S. federal and Canadian jurisdictions and California and Maryland state jurisdictions. The Company is subject to U.S. federal and state income tax examinations by tax authorities for tax years 2000 through 2015 due to net operating losses that are being carried forward for tax purposes.

The Company does not have any uncertain tax positions or unrecognized tax benefits at March 31, 2015 and 2014. The Company’s policy is to recognize interest and penalties related to income taxes as components of interest expense and other expense, respectively.

12. Licensing and Collaborative Agreements

University Health Network

On September 17, 2007, we entered into a Sponsored Research Collaboration Agreement (SRCA) with University Health Network (UHN) to develop certain stem cell technologies for drug discovery, development and rescue technologies. The SRCA was amended on April 19, 2010 to extend the term to five years and give us various options to extend the term for an additional three years. On December 15, 2010, we entered into a second amendment with UHN to expand the scope of work to include induced pluripotent stem cell technology and to further expand the scope of research and term extension options. On April 25, 2011, we and UHN amended the SRCA a third time to expand the scope to include therapeutic and stem cell therapy applications of induced pluripotent cells and to extend the date during which we may elect to fund additional projects to April 30, 2012. On October 24, 2011, we and UHN amended the SRCA a fourth time to identify five key programs to further support our core drug rescue initiatives and potential cell therapy applications. In October 2012, we issued a promissory note in the principal amount of $549,500 and a warrant to UHN as payment in full for services rendered under the fourth amendment. We also entered into Amendment No. 5 to the SRCA establishing the sponsored research projects and the sponsored research budgets under the SRCA from October 1, 2012 to September 30, 2013. During our fiscal year ended March 31, 2015, our financial condition precluded further sponsored research activities with UHN.

Concurrent with the execution of the fourth amendment to the SRCA, we also entered into a License Agreement with UHN under the terms of which UHN granted us exclusive rights to the use of a novel molecule that can be employed in the identification and isolation of mature and immature human cardiomyocytes from pluripotent stem cells, as well as methods for the production of cardiomyocytes from pluripotent stem cells that express this marker. In consideration for the grant of the license, we have agreed to make payments to UHN totaling $3.9 million, if, and when, we achieves certain commercial milestones set forth in the License Agreement, and to pay UHN royalties based on our receipt of revenue attributable to the licensed patents.

U.S. National Institutes of Health

During fiscal years 2006 through 2008, the U.S. National Institutes of Health ("NIH") awarded VistaGen California a $4.2 million grant to support preclinical development of AV-101, our lead drug candidate for treatment of neuropathic pain and other neurodegenerative diseases such as Huntington’s and Parkinson’s diseases. In June 2009, the NIH awarded VistaGen California a $4.2 million grant to support the Phase I clinical development of AV-101, which amount was subsequently increased to a total of $4.6 million in July 2010. The grant expired in the ordinary course on June 30, 2012 and all funds had been expended. In February 2015, we entered into a Cooperative Research and Development Agreement with the National Institute of Mental Health to collaborate on an NIH-sponsored Phase 2 clinical study of the efficacy and safety of AV-101 in subjects with MDD. The study is expected to commence late in the third quarter of 2015 and be completed in 2016.

Cato Research Ltd.

We have built a strategic development relationship with Cato Research Ltd. (“CRL”), a global contract research and development organization, or CRO, and an affiliate of one of the Company’s largest institutional stockholders. CRL has provided us with access to essential CRO services and regulatory expertise supporting our AV-101 preclinical and clinical development programs and other projects. We recorded research and development expenses for CRO services provided by CRL in the amounts of $38,100 and $52,500 for the fiscal years ended March 31, 2015 and 2014, respectively. In October 2012, we issued an unsecured promissory note in the principal amount of $1,009,000, and a warrant exercisable for 50,450 shares of our common stock, as payment in full of all amounts owed to CRL for CRO services rendered to us through December 31, 2012.

Stock Option Plans and 401(k) Plan

13. Stock Option Plans and 401(k) Plan

We have the following share-based compensation plans.

2008 Stock Incentive Plan

Our 2008 Stock Incentive Plan (the “2008 Plan”) was adopted by the shareholders of VistaGen California on December 19, 2008 and assumed by the Company in connection with the Merger. The maximum number of shares of our common stock that may be granted pursuant to the 2008 Plan is 250,000 shares, subject to adjustments for stock splits, stock dividends or other similar changes in the common stock or capital structure.

1999 Stock Incentive Plan

Our 1999 Stock Incentive Plan (the “1999 Plan”) was adopted by the shareholders of VistaGen California on December 6, 1999 and assumed by the Company in connection with the Merger. We initially reserved 45,000 shares for the issuance of awards under the 1999 Plan. The 1999 Plan has terminated under its own terms and, as a result, no awards may currently be granted under the 1999 Plan. The unexpired options and awards that have already been granted pursuant to the 1999 Plan remain operative.

Description of the 2008 Plan

Under the terms of the 2008 Plan, the Compensation Committee of our Board of Directors may grant shares, options or similar rights having either a fixed or variable price related to the fair market value of the shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions, or any other security with the value derived from the value of the shares. Such awards include stock options, restricted stock, restricted stock units, stock appreciation rights and dividend equivalent rights.

The Compensation Committee may grant nonstatutory stock options under the 2008 Plan at a price of not less than 100% of the fair market value of our common stock on the date the option is granted. Incentive stock options under the 2008 Plan may be granted at a price of not less than 100% of the fair market value of our common stock on the date the option is granted. Incentive stock options granted to employees who, on the date of grant, own stock representing more than 10% of the voting power of all of our classes of stock are granted at an exercise price of not less than 110% of the fair market value of our common stock and the maximum term of such incentive stock options may not exceed five years. The maximum term of an incentive stock option granted to any other participant may not exceed ten years. The Compensation Committee determines the term and exercise or purchase price of all other awards granted under the 2008 Plan. The Compensation Committee also determines the terms and conditions of awards, including the vesting schedule and any forfeiture provisions. Awards under the 2008 Plan may vest upon the passage of time or upon the attainment of certain performance criteria established by the Compensation Committee. We currently have no performance-based awards outstanding.

Unless terminated sooner, the 2008 Plan will automatically terminate in 2017. The Board of Directors may at any time amend, suspend or terminate our 2008 Plan.

We did not grant any stock options during fiscal 2015. During the third quarter of fiscal 2014, when the quoted market price of our common stock was $8.00 per share, we reduced the exercise price of an aggregate of 196,213 outstanding options to purchase shares of its common stock at exercise prices between $15.00 per share and $59.80 per share held by certain employees, including the Company’s officers and directors, and by certain consultants to $8.00 per share or $10.00 per share. These reductions in exercise price were accounted for as a modification of the options and resulted in a charge of $252,000.

The following table summarizes share-based compensation expense, including share-based expense related to the March 2015 and March 2014 grants of warrants to certain of our officers and to our independent directors as described in Note 9, Capital Stock, included in the accompanying Consolidated Statement of Operations and Comprehensive Loss for the years ended March 31, 2015 and 2014.

		1,611,300		683,900

Total stock-based compensation expense	$	2,460,100	$	1,137,300

We used the Black-Scholes option valuation model with the following assumptions to determine share-based compensation expense related to option grants during the fiscal years ended March 31, 2015 and 2014:

	Fiscal Years Ended March 31,
	2015	2014

Exercise price	not applicable	$8.00 to $16.40
Market price on date of grant	not applicable	$8.00 to $16.40
Risk-free interest rate	not applicable	1.08% to 2.53%
Expected term (years)	not applicable	6.25 to 10.0
Volatility	not applicable	87.9% to 103.2%
Expected dividend yield	not applicable	0%

Fair value per share at grant date	not applicable	$6.38 to $13.63

The expected term of options represents the period that our share-based compensation awards are expected to be outstanding. We have calculated the weighted-average expected term of the options using the simplified method as prescribed by Securities and Exchange Commission Staff Accounting Bulletins No. 107 and No. 110 (“SAB No. 107 and 110”). The utilization of SAB No. 107 and 110 was based on the lack of relevant historical data due to our limited historical experience as a publicly traded company as well as the lack of liquidity resulting from the limited number of freely-tradable shares of our common stock. Limited historical experience and lack of liquidity in our stock also resulted in our decision to utilize the historical volatilities of a peer group of public companies’ stock over the expected term of the option in determining our expected volatility assumptions. The risk-free interest rate for periods related to the expected life of the options is based on the U.S. Treasury yield curve in effect at the time of grant. The expected dividend yield is zero, as we have not paid any dividends and do not anticipate paying dividends in the near future. We calculated the forfeiture rate based on an analysis of historical data, as it reasonably approximates the currently anticipated rate of forfeitures for granted and outstanding options that have not vested.

The following table summarizes activity for the fiscal years ended March 31, 2015 and 2014 under our stock option plans:

At March 31, 2015, there were 40,491 shares of our common stock remaining available for grant under the 2008 Plan. There were no option exercises during the years ended March 31, 2015 or 2014.

Aggregate intrinsic value is the sum of the amounts by which the fair value of the underlying common stock exceeded the exercise price of the option (in-the-money-options). Based on the $10.00 per share quoted market price of our common stock on March 31, 2015, the aggregate intrinsic value of outstanding options at that date was $99,200, of which $92,900 related to exercisable options.

As of March 31, 2015, there was approximately $71,700 of unrecognized compensation cost related to non-vested share-based compensation awards from the 2008 Plan, which is expected to be recognized through May 2016. Additionally, at March 31, 2015 there was approximately $27,000 of unrecognized compensation cost related to unvested warrant grants to independent directors and officers, which is expected to be recognized through March 2016 absent any conditions which would accelerate the vesting of the awards and corresponding expense recognition.

401(k) Plan

Through a third-party agent, we maintain a retirement and deferred savings plan for our employees. This plan is intended to qualify as a tax-qualified plan under Section 401(k) of the Internal Revenue Code. The retirement and deferred savings plan provides that each participant may contribute a portion of his or her pre-tax compensation, subject to statutory limits. Under the plan, each employee is fully vested in his or her deferred salary contributions. Employee contributions are held and invested by the plan’s trustee. The retirement and deferred savings plan also permits us to make discretionary contributions, subject to established limits and a vesting schedule. To date, we have not made any discretionary contributions to the retirement and deferred savings plan on behalf of participating employees.

Cato Holding Company (CHC), doing business as Cato BioVentures (CBV), the parent of CRL, is one of our largest institutional stockholders at March 31, 2015, holding common stock and warrants to purchase our common stock. Shawn Singh, our Chief Executive Officer and member of our Board of Directors, served as Managing Principal of CBV and as an officer of CRL until August 2009. On October 10, 2012, we issued to CHC an unsecured promissory note in the principal amount of $310,400 (the 2012 CHC Note) and a five-year warrant to purchase 12,500 restricted shares of our common stock at a price of $30.00 per share (the CHC Warrant). Additionally, on October 10, 2012, we issued to CRL: (i) an unsecured promissory note in the initial principal amount of $1,009,000, which is payable solely in restricted shares of our common stock and which accrues interest at the rate of 7.5% per annum, compounded monthly (the CRL Note), as payment in full for all contract research and development services and regulatory advice rendered to us by CRL through December 31, 2012 with respect to the preclinical and clinical development of AV-101, and (ii) a five-year warrant to purchase, at a price of $20.00 per share, 50,450 restricted shares of our common stock. The 2012 CHC Note and the CRL Note mature on March 31, 2016.

During fiscal year 2007, VistaGen California entered into a contract research organization arrangement with CRL related to the development of AV-101, under which we incurred expenses of $38,100 and $52,500 for the fiscal years ended March 31, 2015 and 2014, respectively. Total interest expense on notes payable to CHC and CRL was $174,800 and $167,900 for the fiscal years ended March 31, 2015 and 2014, respectively.

Upon the approval of its Board of Directors, in December 2006, VistaGen California accepted a full-recourse promissory note in the amount of $103,400 from Mr. Shawn Singh in payment of the exercise price for options and warrants to purchase an aggregate of 6,320 restricted shares of VistaGen California’s common stock. The note accrued interest at a rate of 4.90% per annum and was due and payable no later than the earlier of (i) December 1, 2016 or (ii) ten days prior to VistaGen California becoming subject to the requirements of the Securities Exchange Act of 1934, as amended (Exchange Act). On May 11, 2011, in connection with the Merger, the $128,200 outstanding balance of principal and accrued interest on this note was cancelled in accordance with Mr. Singh's employment agreement and recorded as additional compensation. In accordance with his employment agreement, Mr. Singh is also entitled to receive an income tax gross-up on the compensation related to the note cancellation. At March 31, 2015 and 2014, we had accrued $101,900 as an estimate of the gross-up amount, but we had not yet paid any of that amount to Mr. Singh.

Between September and December 2013, Mr. Singh provided short-term cash advances aggregating $64,000 to meet our short-term working capital requirements. In lieu of cash repayment of the advances, in December 2013, Mr. Singh elected to invest $50,000 of the balance due him in the 2013 Unit Private Placement. At March 31, 2015, we have completely repaid the balance of the advances and the $50,000 promissory note issued in connection with his investment in the 2013 Unit Private Placement to Mr. Singh.

From time to time, we may become involved in claims and other legal matters arising in the ordinary course of business. Management is not currently aware of any claims made or other legal matters that will have a material adverse effect on our consolidated financial position, results of operations or its cash flows.

We indemnify our officers and directors for certain events or occurrences while the officer or director is or was serving at our request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. We will indemnify the officers or directors against any and all expenses incurred by the officers or directors because of their status as one of our directors or executive officers to the fullest extent permitted by Nevada law. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. We have a director and officer insurance policy which limits our exposure and may enable us to recover a portion of any future amounts paid. We believe the fair value of these indemnification agreements is minimal. Accordingly, there are no liabilities recorded for these agreements at March 31, 2015 or 2014.

In the normal course of business, we provide indemnifications of varying scopes under agreements with other companies, typically clinical research organizations, investigators, clinical sites, suppliers and others. Pursuant to these agreements, we generally indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified parties in connection with the use or testing of our product candidates or with any U.S. patents or any copyright or other intellectual property infringement claims by any third party with respect to our product candidates. The terms of these indemnification agreements are generally perpetual. The potential future payments we could be required to make under these indemnification agreements is unlimited. We maintain liability insurance coverage that limits our exposure. We believe the fair value of these indemnification agreements is minimal.

Subsequent Events

16. Subsequent Events

We have evaluated subsequent events through the date of this report and have identified the following material events and transactions that occurred after March 31, 2015.

2014 Unit Private Placement

From April 1, 2015 through May 14, 2015, we entered into securities purchase agreements with accredited investors pursuant to which we sold to such accredited investors Units, for aggregate cash proceeds of $280,000, consisting of (i) 10% convertible notes in the aggregate face amount of $280,000 due between April 30, 2015 and May 15, 2015 or automatically convertible into securities we may issue upon the consummation of a Qualified Financing, as defined in the note (ii) an aggregate of 33,000 restricted shares of our common stock; and (iii) warrants exercisable through December 31, 2016 to purchase an aggregate of 24,250 restricted shares of our common stock at an exercise price of $10.00 per share.

Creation of Series B Preferred Stock

On May 7, 2015, we filed a Certificate of Designation of the Relative Rights and Preferences of the Series B 10% Preferred Stock of VistaGen Therapeutics, Inc. (Certificate of Designation) with the Nevada Secretary of State to designate 4.0 million shares of our authorized preferred stock as Series B 10% Convertible Preferred Stock (Series B Preferred).

Each share of Series B Preferred is convertible, at the option of the holder (Voluntary Conversion), into one (1) share of our common stock at a fixed conversion price of $7.00 per share (Conversion Price). The Conversion Price is subject to adjustment only for customary stock dividends, reclassifications, splits and similar transactions set forth in the Certificate of Designation. All outstanding shares of Series B Preferred are also convertible automatically into shares of our common stock (“Automatic Conversion”) upon the closing or effective date of any of the following transactions or events: (i) a strategic transaction involving AV-101 with an initial up-front cash payment to us of at least $10.0 million; (ii) a registered public offering of our common stock with aggregate gross proceeds to us of at least $10.0 million; or (iii) for 20 consecutive trading days, our common stock trades at least 20,000 shares per day with a daily closing price of at least $12.00 per share; provided, however, that Automatic Conversion and Voluntary Conversion (collectively, Conversion) are subject to certain beneficial ownership blockers as set forth in the Certificate of Designation.

Prior to Conversion, shares of Series B Preferred will accrue dividends, payable only in shares of our common stock, at a rate of 10% per annum (Accrued Dividend). The Accrued Dividend will be payable on the date of either a Voluntary Conversion or Automatic Conversion solely in that number of shares of common stock equal to the Accrued Dividend, divided by the Conversion Price.

Agreement with Platinum

On May 5, 2015, we entered into an Agreement with Platinum, which, as modified by an Acknowledgement and Agreement, became effective on May 12, 2015 (Platinum Agreement). Under the Platinum Agreement, Platinum:

· Converted all of the approximately $4.5 million outstanding balance (principal and accrued but unpaid interest) of the Senior Notes we issued to Platinum into 641,335 shares of Series B Preferred, thereby cancelling approximately $4.5 million of our outstanding indebtedness;

· Released all of its security interests in our assets and those of our subsidiaries by terminating the Amended and Restated Security Agreement, IP Security Agreement and Negative Covenant, each dated October 11, 2012 between us and Platinum; and

· Converted all of the approximately $1.3 million outstanding balance (principal and accrued but unpaid interest) of the 2014 Unit Notes that we issued to Platinum into 240,305 shares of Series B Preferred and five-year warrants to purchase 240,305 shares of our common stock at a fixed exercise price of $7.00 per share (Series B Warrants), thereby cancelling approximately $1.3 million of our outstanding indebtedness; and

· Purchased approximately $1.5 million (including accrued but unpaid interest thereon) of outstanding 2014 Unit Notes we issued to various investors from the respective holders thereof (Investor 2014 Unit Notes ) and converted the entire outstanding balance of the Investor 2014 Unit Notes into 265,699 shares of Series B Preferred and Series B Warrants to purchase 265,699 shares of our common stock, thereby cancelling approximately $1.5 million of our outstanding indebtedness; and

· Entered into a Securities Purchase Agreement (SPA) to purchase, for $1.0 million, a total of 142,857 shares of Series B Preferred and a Series B Warrant to purchase 142,857 shares of our common stock, on or before June 11, 2015 (a portion of which purchase was completed on June 19, 2015); and

· Amended the Platinum Warrants (all warrants previously issued by us to Platinum in connection with the Senior Notes) and the Series A Exchange Warrant to:

o fix the exercise price thereof at $7.00 per share;

o eliminate the exercise price reset features and fix the number of shares of our common stock issuable thereunder; and

o eliminate the cashless exercise provisions from the Platinum Warrants and the Series A Exchange Warrant; and

· Agreed to refrain from the sale of any shares of our common stock held by Platinum or its affiliates until the earlier to occur of an effective registration statement relating to resale of certain specified shares of common stock under the Securities Act of 1933, as amended, or the closing price of our common stock is at least $15.00 per share.

As additional consideration for the agreements of Platinum under the Platinum Agreement, we issued to Platinum 400,000 shares of Series B Preferred and Series B Warrants to purchase 1.2 million shares of our common stock, and exchanged 30,000 shares of our common stock currently beneficially owned or controlled by Platinum for 30,000 shares of Series B Preferred.

Conversion of 2014 Unit Notes

Effective May 20, 2015, holders of the remaining approximately $1.8 million outstanding balance (principal and accrued but unpaid interest) of 2014 Unit Notes converted such notes into 327,016 shares of Series B Preferred and Series B Warrants to purchase 327,016 shares of our common stock, thereby cancelling an additional approximately $1.8 million of our outstanding indebtedness.

Sale of Series B Preferred Units

Between May 26, 2015 and June 25, 2015, we sold to accredited investors and institutions an aggregate of $557,500 of units in our Series B Preferred Unit offering, which units consist of Series B Preferred and Series B Warrants (together Series B Preferred Units), including $100,000 to Platinum. We issued 79,646 shares of Series B Preferred and Series B Warrants to purchase 79,646 shares of our common stock. We have received an aggregate of $557,500 in cash proceeds from the sale of the Series B Preferred Units.

Conversion of Notes and Accounts Payable

During May and June 2015, holders of certain of our promissory notes outstanding at March 31, 2015 and thereafter, including Morrison & Foerster, Cato Research Ltd., University Health Network, and McCarthy Tetrault, and certain other service providers converted notes payable or accounts payable having an aggregate outstanding balance of approximately $5.8 million (principal and accrued but unpaid interest and certain adjustments thereto) into 831,577 shares of Series B Preferred, thereby cancelling an additional approximately $5.8 million of our outstanding debt.
