NOTE 1. ORGANIZATION AND BUSINESS ACTIVITIES | |
Protalex, Inc., a Delaware corporation, (“we,” “us,” “our,” the “Company” or “its”) is a development stage company focused on the development of a class of biopharmaceutical drugs for treating autoimmune and inflammatory diseases including rheumatoid arthritis (RA). Our lead product, PRTX-100, is a formulation of a proprietary, highly-purified form of staphylococcal protein A, which is an immunomodulatory protein produced by bacteria. PRTX-100 has demonstrated effectiveness in animal models of autoimmune diseases and has demonstrated activity on cultured human immune cells at very low concentrations, although the effectiveness of PRTX-100 shown in pre-clinical studies using animal models may not be predictive of the results that we would see in future human clinical trials. The safety, tolerability and PK of PTRX-100 in humans have now been characterized in four clinical studies, with a fifth clinical study nearing completion as detailed below. We are currently seeking regulatory approval to initiate clinical studies in an orphan indication and approval for an orphan drug designation. We do not anticipate generating operating revenue for the foreseeable future and do not currently have any products that are marketable. | |
In August 2010, we commenced a multi-center Phase 1b clinical trial of PRTX-100 in South Africa in adult patients with active RA on methotrexate or leflunomide (the “PRTX-100-103 Study”). The PRTX-100-103 Study served to evaluate safety and potential efficacy of PRTX-100 in patients with active RA and was approved to enroll up to 40 patients in four dose-escalating cohorts. In January 2012, we completed patient dosing in the PRTX-100-103 Study with a total of 37 patients enrolled in four cohorts ranging from 0.15 micrograms/kg to 1.50 micrograms/kg of PRTX-100 or placebo, administered weekly for four weeks. Measures of safety, PK and disease activity were evaluated over 16 weeks following the first dose. The PRTX-100-103 Study results demonstrated that PRTX-100 was generally safe and well-tolerated in patients with active RA at all tested dose levels. More patients in the 0.90 micrograms/kg and 1.50 micrograms/kg cohorts showed improvement in their CDAI than did patients in the lower dose or placebo cohorts. | |
In November 2012, we commenced enrollment in the United States for a new multicenter Phase 1b randomized, multiple-dose, dose-escalation study (the “PRTX-100-104 Study”) of PRTX-100 in combination with methotrexate or leflunomide in adult patients with active RA. The sequential dose-escalation phase of this study was expected to enroll up to 40 patients into five cohorts ranging from 1.50 micrograms/kg up to 18.0 micrograms/kg of PRTX-100 or placebo. At each dose, one quarter of patients would receive a placebo treatment. Similar to the PRTX-100-103 Study, the primary objective of the PRTX-100-104 Study is to assess the safety and tolerability of intravenous PRTX-100 administered weekly over five weeks in patients with active RA on methotrexate or leflunomide therapy. The secondary objectives include determining the effects of PRTX-100 on measures of disease activity, assessing the immunogenicity and evaluating the PK parameters after repeated doses, and determining possible relationships between the immunogenicity of PRTX-100 and safety, PK and efficacy parameters. | |
In August 2013, following a planned interim safety review by our Independent Data Safety Monitoring Committee (SMC) and upon completion of the fourth cohort, we expanded the 3.0 microgram, 6.0 microgram, and 12.0 micrograms/kg dose cohorts of the PRTX-100-104 Study. An additional nine patients were enrolled in the expansion cohort that was completed in October 2013. In total, the first four dose-escalating cohorts of the PRTX-100-104 Study, which included these three expanded cohorts, enrolled 41 patients with doses ranging from 1.5 micrograms/kg up to 12.0 micrograms/kg. | |
In November 2013, following completion of the Cohort 4 expansion cohorts, we initiated enrollment of the fifth and final cohort (Cohort 5) in the PRTX 100-104 Study. The Cohort 5 sub-study will enroll up to 20 patients who will receive five weekly doses of PRTX-100 followed by four additional monthly maintenance doses of PRTX-100 in the 3.0 micrograms/kg to 6.0 micrograms/kg range. Patients could receive up to nine doses of PRTX-100 over the six month study visit period. The primary objective of the Cohort 5 sub-study is to assess safety and tolerability of these doses administered on a modified schedule. Secondary objectives include determining the effects of PRTX-100 on measures of disease activity, assessing the immunogenicity and evaluating the PK parameters after repeated doses, and determining possible relationships between the immunogenicity of PRTX-100 and safety, PK and efficacy parameters. | |
Currently, all 20 patients have been enrolled into Cohort 5 at six study sites in the United States. A total of nine study sites were used in the PRTX-100-104 Study. | |
We maintain an administrative office in Florham Park, New Jersey and currently outsource all of our product development and regulatory activities, including clinical trial activities, manufacturing and laboratory operations, to third-party contract research organizations, consultants and facilities. | |
In April 2009, under prior management, we ceased all operations and terminated all employees in light of insufficient funds to continue our clinical trials and related product development. Our business was dormant until current management took control of our operations in November 2009 following the change in control transaction more fully described below. We are currently actively pursuing the commercial development of PRTX-100 for the treatment of RA. | |
On December 8, 2010, we effected a reverse stock split of the outstanding shares of our common stock, with par value of $0.00001 per share (“Common Stock”), on the basis of one new share of Common Stock for each five shares of Common Stock outstanding. All references in this Report to number of shares, price per share and weighted average number of shares outstanding of Common Stock prior to this reverse stock split have been adjusted to reflect the reverse stock split on a retroactive basis, unless otherwise noted. | |

CHANGE OF OWNERSHIP TRANSACTION | ' |
NOTE 2. CHANGE OF OWNERSHIP TRANSACTION | |
On November 11, 2009 (the “Effective Date”), we consummated a financing transaction (the “Financing”) in which we raised $3,000,000 of working capital pursuant to a Securities Purchase Agreement (the “Purchase Agreement”) with Niobe Ventures, LLC, a Delaware limited liability company (“Niobe”). Pursuant to the Purchase Agreement, we issued to Niobe (i) 8,695,652 restricted shares of our Common Stock at a purchase price of $0.23 per share (or $2 million in the aggregate) and (ii) a senior secured convertible promissory note in the principal amount of $1 million convertible into shares of our Common Stock at an initial conversion price equal to $0.23 per share (the “$1 Million Secured Note”). On February 11, 2011, Niobe converted the $1 Million Secured Note, including $37,500 of accrued interest thereon, into 4,510,870 shares of Common Stock. | |
As contemplated by the Purchase Agreement, all of our executive officers and all of the members of our Board of Directors (the “Board”) prior to the closing of the Financing, with the exception of Frank M. Dougherty, resigned effective concurrently with the closing of the Financing. Mr. Dougherty resigned effective upon the expiration of the 10-day notice period required by Rule 14f-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In addition, effective upon the closing of the Financing, our Board appointed Arnold P. Kling as a director and then elected him as our president and elected Kirk M. Warshaw as our chief financial officer and secretary. | |
In addition, on the Effective Date, we terminated (i) the Investor Rights Agreement dated September 18, 2003 among us, vSpring SBIC L.P. (“vSpring”) and certain of the investors set forth on Schedule A thereto and the Registration Rights Agreement dated May 25, 2005 among us, vSpring and certain of the investors set forth on Schedule I thereto in accordance with their respective terms and (ii) stock options exercisable for an aggregate of 246,714 shares of Common Stock (approximately 41% of our then outstanding stock options). | |
On February 11, 2011, for the purpose of providing us with additional working capital, pursuant to an existing Credit Facility Agreement dated as of December 2, 2009 (the “Facility”) with Niobe, we issued to Niobe a senior secured convertible promissory note in the principal amount of $2 million (the “$2 Million Secured Convertible Note”). The $2 Million Secured Convertible Note provided for conversion into shares of our Common Stock at a conversion price of $0.23 per share, for an aggregate of 8,695,652 shares of our Common Stock (net of accrued interest thereon), bore interest at a rate of 3% per annum and matured on December 31, 2013. The original maturity was December 31, 2012 but in December 2012 Niobe agreed, for no consideration, to extend the maturity date to December 31, 2013. | |
The $2 Million Secured Convertible Note was convertible at any time, by the holder, subject only to the requirement that we have sufficient authorized shares of Common Stock after taking into account all outstanding shares of Common Stock and the maximum number of shares issuable under all issued and outstanding convertible securities. In addition, the $2 Million Secured Convertible Note would automatically be converted if we undertake certain Fundamental Transactions, as defined in the $2 Million Secured Convertible Note, (such as a merger, sale of all of our assets, exchange or tender offer, or reclassification of our stock or compulsory exchange). The $2 Million Secured Convertible Note also provided for the adjustment of the conversion price in the event of stock dividends and stock splits, and provided for acceleration of maturity, at the holder’s option, upon an event of default, as defined in the $2 Million Secured Convertible Note. On August 27, 2013, Niobe converted the principal and accrued interest under the $2 Million Secured Convertible Note of $155,000 into 9,369,565 shares of Common Stock. | |
On February 1, 2012, we raised $1,000,000 of working capital pursuant to a loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $1,000,000, which bore interest at a rate of 3% per annum and had a maturity date of February 1, 2014 (the “February 2012 Secured Note”). | |
On June 5, 2012, we raised an additional $1,000,000 of working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $1,000,000, which bore interest at a rate of 3% per annum and had a maturity date of May 31, 2014 (the “June 2012 Secured Note”). | |
On October 1, 2012, we raised $800,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $800,000, which bore interest at a rate of 3% per annum and had a maturity date of October 1, 2014 (the “October 2012 Secured Note”). | |
On December 3, 2012, we raised $700,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $700,000, which bore interest at a rate of 3% per annum and had a maturity date of October 1, 2014 (the “December 2012 Secured Note”). | |
Collectively, the February 2012 Secured Note, the June 2012 Secured Note, the October 2012 Secured Note and the December 2012 Secured Note are hereinafter referred to as the “2012 Secured Notes.” | |
On January 18, 2013, we raised $2,500,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $2,500,000, which bore interest at a rate of 3% per annum and had a maturity date of January 15, 2015 (the “January 2013 Secured Note”). | |
On May 13, 2013, we raised $2,000,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $2,000,000, which bore interest at a rate of 3% per annum and had a maturity date of May 13, 2015 (the “May 2013 Secured Note”). | |
On August 27, 2013, the Company raised $1,000,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $1,000,000, which bore interest at a rate of 3% per annum and had a maturity date of August 27, 2015 (the “August 2013 Secured Note”). | |
Collectively, the January 2013 Secured Note, the May 2013 Secured Note, and the August 2013 Secured Note are hereinafter referred to as the “2013 Secured Notes.” | |
Collectively, the 2012 Secured Notes and the 2013 Secured Notes represented a total of $9,000,000 in principal amount of loans from Niobe and are hereinafter referred to as the “Secured Notes.” | |
On October 11, 2013, we issued a Consolidated, Amended and Restated Promissory Note to Niobe in the principal amount of $9,219,366.67 (the “Consolidated Note”). The face amount of the Consolidated Note reflects the $9.0 million aggregate principal amount of the Secured Notes plus interest accrued at 3% per annum on each note from its respective date of issuance. The terms of the Consolidated Note are identical to the Secured Notes except that: (a) the maturity date is September 1, 2015, which is after the latest maturity date of any of the Secured Notes; and (b) it provides for partial mandatory repayment in the event that the Company receives aggregate gross proceeds in excess of $7.5 million from a single or multiple “Liquidity Events” in an amount equal to twenty-five (25%) percent of such gross proceeds. A “Liquidity Event” means (a) the sale of any of our equity, or equity-linked, securities, and (b) the receipt of proceeds, directly or indirectly related to a development and/or commercialization relationship entered into with an unaffiliated third party. In the Secured Notes, the entire principal amount of each note was due, at Niobe’s election, upon the consummation of an equity financing of $7.5 million or greater. Consistent with the terms of the Secured Notes and related security agreements entered into, our obligations under the Consolidated Note are secured by a first priority perfected security interest in all of our assets pursuant to a Consolidated, Amended and Restated Security Agreement dated October 11, 2013 with Niobe. | |
On January 23, 2014, we consummated a private placement financing to accredited investors of 471,334 shares of Common Stock at $6.00 per share resulting in gross proceeds of $2,828,000. We realized net proceeds, after the costs associated with the private placement, of $2,781,603. No commissions were payable in connection with the financing transaction. Proceeds of the financing will be used for working capital purposes, principally to fund ongoing clinical trials and studies and related activities. The investors in the offering were granted piggy-back registration rights in connection with certain registration statements filed by us in the future, subject to certain exceptions, including a registration statement filed in connection with a primary offering by us. | |
The securities issued in the aforementioned financings were issued in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended (the “Act”) pursuant to Sections 4(a)(2) and 4(a)(5) and Regulation D promulgated thereunder. The offer, sale and issuance of such securities were made without general solicitation or advertising. The securities were offered and issued only to “accredited investors” as such term is defined in Rule 501 under the Act. | |

GOING CONCERN | ' |
NOTE 3. GOING CONCERN | |
The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplate our continuation as a going concern. Our ability to continue as a going concern is dependent upon developing products that are regulatory approved and market accepted. There is no assurance that these plans will be realized in whole or in part. The financial statements do not include any adjustments that might result from the outcome of these uncertainties. | |
Since inception, we have incurred an accumulated deficit of $69,788,410 through February 28, 2014. For the years ended May 31, 2013 and 2012, we had net losses of $6,280,234 and $4,444,584, respectively, and for the nine months ended February 28, 2014, we had a net loss of $8,053,357. We used $4,733,349 and $2,351,630 of cash in operating activities for the years ended May 31, 2013 and 2012, respectively, and $3,522,190 during the nine months ended February 28, 2014. As of February 28, 2014, we had cash and cash equivalents of $2,716,459 and net working capital of $2,275,878. We incurred negative cash flow from operating activities since our inception. We have spent, and subject to obtaining additional financing, expect to continue to spend, substantial amounts in connection with executing our business strategy, including continued development efforts relating to PRTX-100. | |
We have no significant payments due on long-term obligations since, as discussed above in Note 2, on October 11, 2013, we issued the Consolidated Note to Niobe. However, we will need to raise additional capital in the future to fund the ongoing FDA approval process. If we are unable to (a) raise additional capital, (b) obtain approval of future Investigational New Drug Applications (“IND”) that we may file in the future, or (c) otherwise achieve successes in the FDA approval process, our ability to sustain our operations would be significantly jeopardized. | |
The most likely sources of additional financing include the public or private sale of equity or debt securities or loans from our majority stockholder. However, additional capital that we may require may not be available on reasonable terms, or at all. | |
In February 2014, we filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission (“SEC”) in connection with a prospective underwritten public offering of up to 3,000,000 shares of Common Stock. We do not presently have any commitment or understanding with any underwriter with respect to any offering. No assurance can be given that we will pursue or consummate an offering, or if we do, that we will be able to raise sufficient additional working capital to fund our operations and satisfy our debt obligations as they become due. | |

NOTE 4. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |||||||||||||
The interim financial data contained in this Report is unaudited; however in the opinion of management, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim period. The financial statements included herein have been prepared by us pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations, although we believe that the disclosures included herein are adequate to make the information presented not misleading. The results of operations in interim periods are not necessarily indicative of the results that may be expected for the full year. | |||||||||||||
Information regarding the our organization and business, accounting policies followed by us and other important information is contained in the notes to the financial statements included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2013. This quarterly report should be read in conjunction with such annual report. | |||||||||||||
Estimates | |||||||||||||
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions affecting the reported amounts of assets, liabilities, revenues and expense, and the disclosure of contingent assets and liabilities. Estimated amounts could differ materially from actual results. | |||||||||||||
Loss Per Common Share | |||||||||||||
The Financial Accounting Standards Board (FASB) has issued guidance for “Earnings Per Share” which provides for the calculation of “Basic” and “Diluted” earnings per share. Basic earnings per share includes no dilution and is computed by dividing net loss to common stockholders by the weighted average number of common shares outstanding for the period. All potentially dilutive securities consisting of employee stock options and warrants have been excluded from the computations since they would be antidilutive. However, these dilutive securities could potentially dilute earnings per share in future periods. As of February 28, 2014 we had potentially dilutive securities consisting of 3,817,543 stock options. As of February 28, 2013, we had potentially dilutive securities consisting of 2,715,543 stock options. | |||||||||||||
Cash and Cash Equivalents | |||||||||||||
For the purposes of reporting cash flows, we consider all cash accounts which are not subject to withdrawal restrictions or penalties, and highly liquid investments with original maturities of 60 days or less to be cash and cash equivalents. The cash and cash equivalent deposits are not insured by The Federal Deposit Insurance Corporation. | |||||||||||||
Share Based Compensation | |||||||||||||
Effective June 1, 2006, we adopted the FASB accounting guidance for fair value recognition provisions of the “Accounting for Share-Based Payment” using the modified prospective method. This standard requires us to measure the cost of employee services received in exchange for equity share options granted based on the grant-date fair value of the options. The cost is recognized as compensation expense over the vesting period of the options. Under the modified prospective method $4,568,763 and $658,488 compensation cost is included in operating expenses for the nine months ended February 28, 2014 and February 28, 2013, respectively. These amounts included both the compensation cost of stock options granted prior to but not yet vested as of June 1, 2006 and compensation cost for all options granted subsequent to May 31, 2006. In accordance with the modified prospective application transition method, prior period results are not restated. Incremental compensation cost for a modification of the terms or conditions of an award is measured by comparing the fair value of the modified award with the fair value of the award immediately before the modification. No tax benefit was recorded as of February 28, 2014 in connection with these compensation costs due to the uncertainty regarding ultimate realization of certain net operating loss carryforwards. We have also implemented the SEC interpretations in Staff Accounting Bulletin (“SAB”) for “Share-Based Payments,” in connection with the adoption of FASB accounting guidance. | |||||||||||||
The Board of Directors adopted and the stockholders approved the 2003 Stock Option Plan in October 2003 which was subsequently amended in October 2005. The plan was adopted to recognize the contributions made by our employees, officers, consultants, and directors, to provide those individuals with additional incentive to devote themselves to our future success, and to improve our ability to attract, retain and motivate individuals upon whom our growth and financial success depends. Under the plan, stock options for up to 900,000 shares may be granted as approved by the Board of Directors or the Compensation Committee. No options granted under the plan are exercisable after the expiration of ten years (or less in the discretion of the Board of Directors or the Compensation Committee) from the date of the grant. The plan will continue in effect until terminated or amended by the Board of Directors. | |||||||||||||
The accounting guidance requires the use of a valuation model to calculate the fair value of each stock-based award. We use the Black-Scholes model to estimate the fair value of stock options granted based on the following assumptions: | |||||||||||||
Expected Term or Life. The expected term or life of stock options granted issued represents the expected weighted average period of time from the date of grant to the estimated date that the stock option would be fully exercised. The weighted average expected option term was determined using a combination of the “simplified method” for plain vanilla options as allowed by the accounting guidance. The “simplified method” calculates the expected term as the average of the vesting term and original contractual term of the options. | |||||||||||||
Expected Volatility. Expected volatility is a measure of the amount by which our stock price is expected to fluctuate. Expected volatility is based on the historical daily volatility of the price of our shares of Common Stock. We estimated the expected volatility of the stock options at grant date. | |||||||||||||
Risk-Free Interest Rate. The risk-free interest rate is based on the implied yield on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term of our stock-based awards. | |||||||||||||
As of February 28, 2014, there were 3,817,543 stock options outstanding of which an aggregate of 37,000 were options granted under the plan and 3,780,543 were non-plan option grants. At February 28, 2014, the aggregate unrecognized compensation cost of unvested options, as determined using a Black-Scholes option valuation model, was approximately $2,865,486 (net of estimated forfeitures) which will be recognized ratably through February 2016. The remaining amount of options will be valued once they vest upon future events. During the nine months ended February 28, 2014, we granted 800,000 stock options and 40,000 options expired. The 800,000 options issued during the nine months ended February 28, 2014 were issued at market. | |||||||||||||
The fair value of the options is estimated on the date of the grant using the Black-Scholes option pricing model with the following assumptions: | |||||||||||||

On the Effective Date (defined in Note 2, above), we issued the $1 Million Secured Note to Niobe, the majority stockholder of Common Stock which is controlled by Arnold P. Kling, our president and a director. The $1 Million Secured Note bore interest at a rate of 3% per annum and had a scheduled maturity date of November 13, 2012. Our obligations under the $1 Million Secured Note were secured by a Security Agreement dated the Effective Date (the “Security Agreement”) which granted Niobe a security interest in substantially all of our personal property and assets, including our intellectual property. On February 11, 2011, Niobe converted the $1 Million Secured Note, including $37,500 of accrued interest thereon, into 4,510,870 shares of Common Stock. | |
On December 2, 2009, we entered into the Facility (defined in Note 2, above) with Niobe pursuant to which Niobe agreed to provide up to $2,000,000 of additional capital in the form of secured loans at any time prior to June 30, 2012, subject to the achievement of certain predetermined benchmarks. In connection with the Facility, on December 2, 2009, the Security Agreement securing our obligations under the $1 Million Secured Note was amended and restated to also secure any incremental obligations under the Facility (the “Amended Security Agreement”). Pursuant to the Amended Security Agreement, Niobe has a security interest in substantially all of our personal property and assets, including our intellectual property to collateralize all amounts due to it under the $1 Million Secured Note and the Facility. | |
Pursuant to the Facility, on February 11, 2011, we received $2,000,000 of additional working capital from Niobe and issued the $2 Million Secured Note to Niobe. The $2 Million Secured Note bore interest at a rate of 3% per annum and, as amended, was scheduled to mature on December 31, 2013. On August 27, 2013, Niobe converted the $2 Million Secured Convertible Note and $155,000 of accrued interest thereunder into 9,369,565 shares of Common Stock. | |

On June 5, 2012, we raised an additional $1,000,000 of working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $1,000,000, which bore interest at a rate of 3% per annum and had a maturity date of May 31, 2014 (the “June 2012 Secured Note”). | |
On October 1, 2012, we raised $800,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $800,000, which bore interest at a rate of 3% per annum and had a maturity date of October 1, 2014 (the “October 2012 Secured Note”). | |
On December 3, 2012, we raised $700,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $700,000, which bore interest at a rate of 3% per annum and had a maturity date of October 1, 2014 (the “December 2012 Secured Note”). | |
Collectively, the February 2012 Secured Note, the June 2012 Secured Note, the October 2012 Secured Note and the December 2012 Secured Note are hereinafter referred to as the “2012 Secured Notes.” | |
On January 18, 2013, we raised $2,500,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $2,500,000, which bore interest at a rate of 3% per annum and had a maturity date of January 15, 2015 (the “January 2013 Secured Note”). | |
On May 13, 2013, we raised $2,000,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $2,000,000, which bore interest at a rate of 3% per annum and had a maturity date of May 13, 2015 (the “May 2013 Secured Note”). | |
On August 27, 2013, the Company raised $1,000,000 of additional working capital pursuant to an incremental loan from Niobe and issued to Niobe a secured promissory note in the principal amount of $1,000,000, which bore interest at a rate of 3% per annum and had a maturity date of August 27, 2015 (the “August 2013 Secured Note”). | |

Collectively, the 2012 Secured Notes and the 2013 Secured Notes represent a total of $9,000,000 in principal amount of loans from Niobe and are hereinafter referred to as the “Secured Notes.” | |
On October 11, 2013, we issued a Consolidated, Amended and Restated Promissory Note to Niobe in the principal amount of $9,219,366.67 (the “Consolidated Note”). The face amount of the Consolidated Note reflects the $9.0 million aggregate principal amount of the Secured Notes plus interest accrued at 3% per annum on each note from its respective date of issuance. The terms of the Consolidated Note are identical to the Secured Notes except that: (a) the maturity date is September 1, 2015, which is after the latest maturity date of any of the Secured Notes; and (b) it provides for partial mandatory repayment in the event that the Company receives aggregate gross proceeds in excess of $7.5 million from a single or multiple “Liquidity Events” in an amount equal to twenty-five (25%) percent of such gross proceeds. A “Liquidity Event” means (a) the sale of any of our equity, or equity-linked, securities, and (b) the receipt of proceeds, directly or indirectly related to a development and/or commercialization relationship entered into with an unaffiliated third party. In the Secured Notes, the entire principal amount of each note was due, at Niobe’s election, upon the consummation of an equity financing of $7.5 million or greater. Consistent with the terms of the Secured Notes and related security agreements entered into, our obligations under the Consolidated Note are secured by a first priority perfected security interest in all of our assets pursuant to a Consolidated, Amended and Restated Security Agreement dated October 11, 2013 with Niobe. | |
The securities issued in the aforementioned financings were issued in reliance upon the exemption from the registration requirements of the Act pursuant to Sections 4(a)(2) and 4(a)(5) and Regulation D promulgated thereunder. The offer, sale and issuance of such securities were made without general solicitation or advertising. The securities were offered and issued only to “accredited investors” as such term is defined in Rule 501 under the Act. | |

Estimates | |||||||||||||
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions affecting the reported amounts of assets, liabilities, revenues and expense, and the disclosure of contingent assets and liabilities. Estimated amounts could differ materially from actual results. | |||||||||||||
Loss per Common Share | ' | ||||||||||||
Loss Per Common Share | |||||||||||||
The Financial Accounting Standards Board (FASB) has issued guidance for “Earnings Per Share” which provides for the calculation of “Basic” and “Diluted” earnings per share. Basic earnings per share includes no dilution and is computed by dividing net loss to common stockholders by the weighted average number of common shares outstanding for the period. All potentially dilutive securities consisting of employee stock options and warrants have been excluded from the computations since they would be antidilutive. However, these dilutive securities could potentially dilute earnings per share in future periods. As of February 28, 2014 we had potentially dilutive securities consisting of 3,817,543 stock options. As of February 28, 2013, we had potentially dilutive securities consisting of 2,715,543 stock options. | |||||||||||||
Cash and Cash Equivalents | ' | ||||||||||||
Cash and Cash Equivalents | |||||||||||||
For the purposes of reporting cash flows, we consider all cash accounts which are not subject to withdrawal restrictions or penalties, and highly liquid investments with original maturities of 60 days or less to be cash and cash equivalents. The cash and cash equivalent deposits are not insured by The Federal Deposit Insurance Corporation. | |||||||||||||
Share Based Compensation | ' | ||||||||||||
Share Based Compensation | |||||||||||||
Effective June 1, 2006, we adopted the FASB accounting guidance for fair value recognition provisions of the “Accounting for Share-Based Payment” using the modified prospective method. This standard requires us to measure the cost of employee services received in exchange for equity share options granted based on the grant-date fair value of the options. The cost is recognized as compensation expense over the vesting period of the options. Under the modified prospective method $4,568,763 and $658,488 compensation cost is included in operating expenses for the nine months ended February 28, 2014 and February 28, 2013, respectively. These amounts included both the compensation cost of stock options granted prior to but not yet vested as of June 1, 2006 and compensation cost for all options granted subsequent to May 31, 2006. In accordance with the modified prospective application transition method, prior period results are not restated. Incremental compensation cost for a modification of the terms or conditions of an award is measured by comparing the fair value of the modified award with the fair value of the award immediately before the modification. No tax benefit was recorded as of February 28, 2014 in connection with these compensation costs due to the uncertainty regarding ultimate realization of certain net operating loss carryforwards. We have also implemented the SEC interpretations in Staff Accounting Bulletin (“SAB”) for “Share-Based Payments,” in connection with the adoption of FASB accounting guidance. | |||||||||||||
The Board of Directors adopted and the stockholders approved the 2003 Stock Option Plan in October 2003 which was subsequently amended in October 2005. The plan was adopted to recognize the contributions made by our employees, officers, consultants, and directors, to provide those individuals with additional incentive to devote themselves to our future success, and to improve our ability to attract, retain and motivate individuals upon whom our growth and financial success depends. Under the plan, stock options for up to 900,000 shares may be granted as approved by the Board of Directors or the Compensation Committee. No options granted under the plan are exercisable after the expiration of ten years (or less in the discretion of the Board of Directors or the Compensation Committee) from the date of the grant. The plan will continue in effect until terminated or amended by the Board of Directors. | |||||||||||||
The accounting guidance requires the use of a valuation model to calculate the fair value of each stock-based award. We use the Black-Scholes model to estimate the fair value of stock options granted based on the following assumptions: | |||||||||||||
Expected Term or Life. The expected term or life of stock options granted issued represents the expected weighted average period of time from the date of grant to the estimated date that the stock option would be fully exercised. The weighted average expected option term was determined using a combination of the “simplified method” for plain vanilla options as allowed by the accounting guidance. The “simplified method” calculates the expected term as the average of the vesting term and original contractual term of the options. | |||||||||||||
Expected Volatility. Expected volatility is a measure of the amount by which our stock price is expected to fluctuate. Expected volatility is based on the historical daily volatility of the price of our shares of Common Stock. We estimated the expected volatility of the stock options at grant date. | |||||||||||||
Risk-Free Interest Rate. The risk-free interest rate is based on the implied yield on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term of our stock-based awards. | |||||||||||||
As of February 28, 2014, there were 3,817,543 stock options outstanding of which an aggregate of 37,000 were options granted under the plan and 3,780,543 were non-plan option grants. At February 28, 2014, the aggregate unrecognized compensation cost of unvested options, as determined using a Black-Scholes option valuation model, was approximately $2,865,486 (net of estimated forfeitures) which will be recognized ratably through February 2016. The remaining amount of options will be valued once they vest upon future events. During the nine months ended February 28, 2014, we granted 800,000 stock options and 40,000 options expired. The 800,000 options issued during the nine months ended February 28, 2014 were issued at market. | |||||||||||||
