NOTE 3 – STOCKHOLDERS’ DEFICIT, STOCK OPTIONS AND WARRANTS
 
The Company has an equity incentive plan, which allows issuance of incentive and non-qualified stock options to employees, directors and consultants of the Company, where permitted under the plan. The exercise price for each stock option is determined by the Board of Directors. Vesting requirements are determined by the Board of Directors when granted and currently range from immediate to three years. Options under this plan have terms ranging from three to ten years.
 
Public Offering of Units
 
On August 31, 2015 (the “Issuance Date”), the Company completed a public offering (the “Offering”) of 1,666,667 Units (the “Units”) as described below. The public offering price in the Offering was $9.00 per Unit, and the purchase price for the underwriter of the Offering (the “Underwriter”) was $8.28 per Unit, resulting in an underwriting discount and commission of $0.72 (or 8.00%) per Unit and total net proceeds to the Company before expenses of $13.8 million. The Company had granted the Underwriter an option for a period of 45 days to purchase up to an additional 250,000 Units solely to cover over-allotments. The Underwriter chose not to purchase any additional Units under the over-allotment option. The Company paid to the Underwriter a non-accountable expense allowance equal to 1% of the gross proceeds of the Offering and agreed to reimburse expenses incurred by the Underwriter up to $70,000.
 
On August 31, 2015, as a result of the consummation of the Offering and the issuance of the 228,343 Exchange Units in the Unit Exchange described below, the Company issued a total of 1,895,010 Units, comprised of a total of aggregate of 75,800 shares of Common Stock (as adjusted for the reverse stock split), 1,895,010 shares of Series B Preferred Stock and 7,580,040 Series A Warrants, (as adjusted for the reverse stock split).
 
Each Unit consisted of one share of common stock, par value $0.01 per share (the “Common Stock”), one share of Series B Convertible Preferred Stock (“Series B Preferred Stock”) and four Series A Warrants. The shares of Common Stock, the shares of Series B Preferred Stock and the Series A Warrants that comprise the Units automatically separated on February 29, 2016.
 
For a description of the terms of the Series B Convertible Preferred Stock included within the Units, see “Series B Preferred Stock” below. For a description of the terms of the Series A Warrants included within the Units, see “Series A Warrants” below.
 
Series A Warrants.
The Series A Warrants separated from the Series B Convertible Preferred Stock and the Common Stock included within the Units as described above and are currently exercisable. The Series A Warrants terminate on August 31, 2020. Each Series A Warrant is exercisable into one share of Common Stock at an initial cash exercise price of $123.75 per share. The Cash exercise price and number of shares of common stock issuable upon cash exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting the Common Stock and the exercise price.
 
Holders may exercise Series A Warrants by paying the exercise price in cash or, in lieu of payment of the exercise price in cash, by electing to receive a number of shares of Common Stock equal to the Black-Scholes Value (as defined below) based upon the number of shares the holder elects to exercise. The number of shares of Common Stock to be delivered according to the following formula, referred to as the “Cashless Exercise.”
 
Total Shares = (A x B)/C
 
Where:
 
 
·
Total shares is the number of shares of Common Stock to be issued upon a Cashless Exercise.
 
·
A is the total number of shares with respect to which the Series A Warrant is then being exercised.
 
·
B is the Black-Scholes Value (as defined below).
 
·
C is the closing bid price of the Common Stock as of two trading days prior to the time of such exercise, provided that in no event may “C” be less than $0.43 per share (subject to appropriate adjustment in the event of stock dividends, stock splits or similar events affecting the Common Stock).
 
The Black-Scholes Value (as defined above) as of September 30, 2016 was $4.319, and the closing bid price of Common Stock as of September 30, 2016, was $4.125. Therefore, an exercise on that date would have resulted in the issuance of .40 shares of Common Stock for each Series A Warrant. Approximately 6,141,115 Series A Warrants have been exercised in cashless exercises as of September 30, 2016, resulting in the issuance of 2,318,663 shares of Common Stock. If all of the remaining 35,084 Series A Warrants that were issued as part of the Units sold in the Offering and part of the Units issued on August 31, 2015 were exercised pursuant to a cashless exercise and the closing bid price of our common stock as of the two trading days prior to the time of such exercise was $10.75 per share or less and the Black-Scholes Value were $4.319 (the Black-Scholes Value as of September 30, 2016), then a total of an additional approximately 564 shares of our common stock would be issued to the holders of such Series A Warrants.
 
The Series A Warrants will not be exercisable or exchangeable by the holder of such warrants to the extent (and only to the extent) that the holder or any of its affiliates would beneficially own in excess of 4.99% of the common stock of the Company, determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the regulations promulgated thereunder.
 
In addition to (but not duplicative of) the adjustments to the exercise price and the number of shares of Common Stock issuable upon exercise of the Series A Warrants in the event of stock dividends, stock splits, reorganizations or similar events, the Series A Warrants provide for certain adjustments if the Company, at any time prior to the three year anniversary of the Issuance Date, (1) declares or makes any dividend or other distribution of its assets (or rights to acquire its assets) to all or substantially all of the holders of shares of Common Stock at any time after the Issuance Date, or (2) grants, issues or sells any options, convertible securities or rights to purchase stock, warrants, securities or other property pro rata to all or substantially all of the record holders of any class of shares of Common Stock. Further, if at any time a Series A Warrant is outstanding, the Company consummates any fundamental transaction, as described in the Series A Warrants and generally including any consolidation or merger into another corporation, or the sale of all or substantially all of our assets, or other transaction in which the Common Stock is converted into or exchanged for other securities or other consideration, the holder of any Series A Warrants will thereafter receive, the securities or other consideration to which a holder or the number of shares of Common Stock then deliverable upon the exercise or exchange of such Series A Warrants would have been entitled upon such consolidation or merger or other transaction.
 
Unit Purchase Option.
The Company, in connection with the Offering, entered into a Unit Purchase Option Agreement, dated as of August 31, 2015 (the “Unit Purchase Option”), pursuant to which the Company granted the Underwriter the right to purchase from the Company up to a number of Units equal to 5% of the Units sold in the Offering (or up to 83,333 Units) or the component securities of such Units at an exercise price equal to 125% of the public offering price of the Units in the Offering, or $11.25 per Unit. The Unit Purchase Option was terminated in May 2016 in exchange for 135,995 shares of common stock.
 
Series B Preferred Stock.
Each share of Series B Preferred Stock became convertible into one share of Common Stock (subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events) as of February 29, 2016. In addition, the Series B Preferred Stock will automatically convert into shares of common stock upon the occurrence of a fundamental transaction, as described in the certificate of designations for the Series B Preferred Stock but including mergers, shares of the company’s assets, changes in control and similar transactions. The Series B Preferred Stock is not convertible by the holder of such preferred stock to the extent (and only to the extent that the holder or any of its affiliates would beneficially own in excess of 4.99% of the common stock of the Company. The Series B Preferred Stock has no voting rights, except for the right to approve certain amendments to the certificate of designations or similar actions. With respect to payment of dividends and distribution of assets upon liquidation or dissolution or winding up of the Company, the Series B Preferred Stock shall rank equal to the common stock of the Company. No sinking fund has been established for the retirement or redemption of the Series B Preferred Stock.
 
Unit Exchange.
On February 4, 2014, the Company raised $2,055,000 in gross proceeds from a private placement of 20,550 shares of Series A Convertible Preferred Stock, par value $0.01, with a stated value of $100 per share (the “Series A Preferred Shares”) and warrants to purchase shares of the Company’s common stock. The Series A Preferred Shares and warrants were sold to investors pursuant to a Securities Purchase Agreement, dated as of February 4, 2014. On August 31, 2015, the Company issued a total of 228,343 Units (the “Exchange Units”) in exchange for the outstanding Series A Preferred Stock which were then cancelled pursuant to an agreement with the holders of the Series A Preferred Shares. The warrants that were issued in connection with the issuance of the Series A Preferred Shares remained outstanding; however, the warrant amounts were reduced so that the warrants are exercisable into an aggregate of 3,391 shares of the Company’s common stock. The Exchange Units were exempt from registration under Section 3(a)(9) of the Securities Act. On August 31, 2015, the Company filed a termination certificate with the Delaware Secretary of State. Following that date there were no shares of Series A Preferred Stock outstanding, and the previously authorized shares of Series A Preferred Stock resumed the status of authorized but issued and undesignated shares of preferred stock of the Company.
 
Redemption of Convertible Notes.
In connection with the closing of the Offering, $933,074 aggregate principal amount of Convertible Notes plus interest and a 40% redeemable premium were redeemed for total payments of $1,548,792. See Note 4. Of this amount, approximately $167,031 was paid to its affiliates in redemption of their Convertible Notes.
 
Registered Exchange Offer for Warrants.
On March 25, 2016, the Company commenced a registered exchange offer (the “Exchange Offer”) to exchange Series B Warrants (the “Series B Warrants”) to purchase shares of our common stock, par value $0.01 per share (the “Warrant Shares”), for up to an aggregate of 3,157,186 outstanding Series A Warrants (the “Series A Warrants”). On March 31, 2016, each Series A Warrant could be exercised on a cashless basis for 10.05 shares of common stock. Each Series B Warrant may be exercised on a cashless basis for one share of common stock. For each outstanding Series A Warrant tendered by holders, we offered to issue 10.2 Series B Warrants, which are subject to cashless exercise at a fixed rate of one share of common stock per Series B Warrant (subject to further adjustment for stock splits, etc.). The Exchange Offer expired at midnight, Eastern time, on April 21, 2016. 1,770,556 Series A Warrants were tendered by holders. The Company delivered an aggregate of 18,059,671 Series B Warrants pursuant to the terms of the Exchange Offer. In addition, between March 31, 2016 and July 6, 2016 1,251,510 Series A Warrants were exercised in cashless exercises, resulting in the issuance of 503,034 shares of common stock.
 
Accounting for share-based payment
 
The Company has adopted ASC 718- Compensation-Stock Compensation ("ASC 718"). Under ASC 718 stock-based employee compensation cost is recognized using the fair value based method for all new awards granted after January 1, 2006 and unvested awards outstanding at January 1, 2006. Compensation costs for unvested stock options and non-vested awards that were outstanding at January 1, 2006, are being recognized over the requisite service period based on the grant-date fair value of those options and awards, using a straight-line method. We elected the modified-prospective method under which prior periods are not retroactively restated.
 
ASC 718 requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model or other acceptable means. The Company uses the Black-Scholes option valuation model which requires the input of significant assumptions including an estimate of the average period of time employees will retain vested stock options before exercising them, the estimated volatility of the Company's common stock price over the expected term, the number of options that will ultimately be forfeited before completing vesting requirements, the expected dividend rate and the risk-free interest rate. Changes in the assumptions can materially affect the estimate of fair value of stock-based compensation and, consequently, the related expense recognized. The assumptions the Company uses in calculating the fair value of stock-based payment awards represent the Company's best estimates, which involve inherent uncertainties and the application of management's judgment. As a result, if factors change and the Company uses different assumptions, the Company's equity-based compensation expense could be materially different in the future.
 
Since the Company's common stock has no significant public trading history, and the Company has experienced no significant option exercises in its history, the Company is required to take an alternative approach to estimating future volatility and estimated life and the future results could vary significantly from the Company's estimates. The Company compiled historical volatilities over a period of 2 to 7 years of 15 small-cap medical companies traded on major exchanges and 10 mid-range medical companies on the OTC Bulletin Board and combined the results using a weighted average approach. In the case of ordinary options to employees the Company determined the expected life to be the midpoint between the vesting term and the legal term. In the case of options or warrants granted to non-employees, the Company estimated the life to be the legal term unless there was a compelling reason to make it shorter.
 
When an option or warrant is granted in place of cash compensation for services, the Company deems the value of the service rendered to be the value of the option or warrant. In most cases, however, an option or warrant is granted in addition to other forms of compensation and its separate value is difficult to determine without utilizing an option pricing model. For that reason the Company also uses the Black-Scholes option-pricing model to value options and warrants granted to non-employees, which requires the input of significant assumptions including an estimate of the average period the investors or consultants will retain vested stock options and warrants before exercising them, the estimated volatility of the Company's common stock price over the expected term, the number of options and warrants that will ultimately be forfeited before completing vesting requirements, the expected dividend rate and the risk-free interest rate. Changes in the assumptions can materially affect the estimate of fair value of stock-based consulting and/or compensation and, consequently, the related expense recognized.
 
Since the Company has limited trading history in its stock and no first-hand experience with how its investors and consultants have acted in similar circumstances, the assumptions the Company uses in calculating the fair value of stock-based payment awards represent its best estimates, which involve inherent uncertainties and the application of management's judgment. As a result, if factors change and the Company uses different assumptions, the Company's equity-based consulting and interest expense could be materially different in the future.
 
Valuation and accounting for options and warrants
 
The Company determines the grant date fair value of options and warrants using a Black-Scholes option valuation model based upon assumptions regarding risk-free interest rate, expected dividend rate, volatility and estimated term.
