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.

On August 25, 2015, the Company, in connection with a public offering (the “Offering”) of the Units, entered into an underwriting agreement (the “Underwriting Agreement”) with Dawson James Securities, Inc., as underwriter (the “Underwriter”). Pursuant to the Underwriting Agreement, the Company agreed to sell 1,666,667 Units. The public offering price for the Units was $9.00 per Unit and the purchase price for the Underwriter under the Underwriting Agreement 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.

Pursuant to the Underwriting Agreement, the Company agreed to issue to the Underwriter a unit purchase option (the “Unit Purchase Option”) more fully described below. The Company had also agreed to pay the Underwriter a non-accountable expense allowance equal to 1% of the gross proceeds of the Offering (excluding any proceeds from the over-allotment option, if any), as well as to reimburse expenses incurred by the Underwriter up to $70,000.

Pursuant to the Underwriting Agreement, the Company agreed to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act, and liabilities arising from breaches of representations and warranties contained in the Underwriting Agreement, or to contribute to payments that the Underwriter may be required to make in respect of those liabilities. The Underwriting Agreement also contains representations, warranties, conditions precedent to closing and other provisions customary for transactions of this nature.

Unit Agreement

The Units were issued pursuant to a Unit Agreement, dated August 31, 2015, between the Company and Corporate Stock Transfer, Inc. (the “Unit Agreement”). Each Unit consists of one share of common stock, par value $0.01 per share (the “Common Stock”), one share of Series B Convertible Preferred Stock and four Series A Warrants. The shares of Common Stock, the shares of Series B Convertible Preferred Stock and the Series A Warrants that comprise the Units will automatically separate on February 29, 2016, which is the six month anniversary of August 31, 2015 (the “Issuance Date”). However, the shares of Common Stock, the shares of Series B Convertible Preferred Stock and the Series A Warrants will separate prior to the expiration of such six-month anniversary if at any time after September 30, 2015, either (i) the closing price of the Company’s common stock on the NASDAQ Capital Market is greater than 200% of the Series A Warrants exercise price for a period of 20 consecutive trading days (the “Trading Separation Trigger”), (ii) all Series A Warrants in a given Unit are exercised for cash (solely with respect to the Units that include the exercised Series A Warrants) (a “Warrant Cash Exercise Trigger”) or (iii) the Units are delisted (the “Delisting Trigger”) from the NASDAQ Capital Market for any reason (any such event, a “Separation Trigger Event”). Upon the occurrence of a Separation Trigger Event, the Units will separate: (i) 15 days after the date of the Trading Separation Trigger, (ii) on the date of any Warrant Cash Exercise Trigger (solely with respect to the Units that include the exercised Series A Warrants) or (iii) the date of the Delisting Trigger, as the case may be. This separation of the Units prior to February 29, 2016 is referred to herein as an “Early Separation.”

For a description of the terms of the Series B Convertible Preferred Stock included within the Units, see “Certificate of Designation for 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.

Warrant Agreement / Series A Warrants

The Series A Warrants are issued pursuant to the Warrant Agency Agreement, dated as of August 31, 2015 between the Company and Corporate Stock Transfer, Inc. (the “Warrant Agreement”). The Series A Warrants are exercisable upon the separation of the Units, provided that all Series A Warrants in a given Unit may be exercised for cash at any time commencing 30 days after the Issuance Date. The Series A Warrants will terminate on the fifth anniversary of the Issuance Date. Each Series A Warrant is exercisable into one share of our common stock at an initial cash exercise price of $4.95 per share. The exercise price and number of shares of common stock issuable upon 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 will be determined 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).

As defined in the Series A Warrants, “Black Scholes Value” means the Black Scholes value of an option for one share of Common Stock at the date of the applicable Cashless Exercise, as such Black Scholes Value is determined, calculated using the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg utilizing (i) an underlying price per share equal to 55% of the Unit price, or $4.95 per share, (ii) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of the Series A Warrant as of the applicable Cashless Exercise, (iii) a strike price equal to the exercise price in effect at the time of the applicable Cashless Exercise, (iv) an expected volatility equal to 135% and (v) a remaining term of such option equal to five years (regardless of the actual remaining term of the Series A Warrant). The Cashless Exercise feature of the Series A Warrants provides for the issuance of a number of shares of Common Stock that increases as the trading market price of the Common Stock decreases, subject to a floor price of $0.43. If all of the 7,580,040 Series A Warrants that were issued as part of the Units sold in the Offering and part of the Exchange Units issued on August 31, 2015, as described below, were exercised pursuant to a Cashless Exercise and the closing bid price of the Common Stock as of the two trading days prior to the time of such exercise was $0.43 per share or less and the Black Scholes Value was $4.326 (the Black Scholes Value as of August 28, 2015), then a total of approximately 76.3 million shares of Common Stock would be issued to the holders of such Series A Warrants.  The potential for such dilutive exercise of the Series A Warrants may depress the price of Common Stock regardless of the Company’s business performance, and could encourage short selling by market participants, especially if the trading price of the Common Stock begins to decrease.

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, if the Company, at any time prior to the three year anniversary of the Issuance Date:

(i) 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 (a “Distribution”), at any time after the Issuance Date, then, in each such case, the holders of the Series A Warrants will be entitled to participate in such Distribution to the same extent that the holders would have participated therein if the holder had held the number of shares of Common Stock acquirable upon complete exercise of the Series A Warrants by either paying the exercise price for such shares of Common Stock in cash in full or by exercising the Series A Warrants in full pursuant to a Cashless Exercise, whichever results in the lesser number of shares of Common Stock issued, as of the date immediately preceding the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution; or

(ii) 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 (the “Purchase Rights”), then the holders of Series A Warrants will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the holder could have acquired if the holder had held the number of shares of Common Stock acquirable upon complete exercise of the Series A Warrant by either paying the exercise price for such shares of Common Stock in cash in full or by exercising the Series A Warrant in full pursuant to a Cashless Exercise, whichever results in the lesser number of shares of Common Stock issued, as of the date immediately preceding the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

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 of 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

Pursuant to the Underwriting Agreement, 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) 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 shall expire on August 25, 2018.

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.

In connection with the Offering, the holders of the Series A Preferred Shares agreed to exchange all of the outstanding Series A Preferred Shares for units with the same terms as the Units (the “Exchange Units”) such that for every dollar of stated value of Series A Preferred Shares tendered the holders would receive an equivalent value of Exchange Units based on the public offering price of the Units in this offering (the “Unit Exchange”). The warrants that were issued in connection with the issuance of the Series A Preferred Shares would remain outstanding; however, the warrant amounts would be reduced so that the warrants will be exercisable into an aggregate of 84,770 shares of the Company’s common stock. The Exchange Units were exempt from registration under the Securities Act pursuant to Section m3(a)(9) thereof.

On August 31, 2015, the Company consummated the Unit Exchange whereby the Company issued a total of 228,343 Units (the “Exchange Units”) in exchange for the outstanding Series A Convertible Preferred Stock which were then cancelled. The Exchange Units were exempt from registration under the Securities Act pursuant to Section 3(a)(9) thereof.

Certificate of Designation for the Series B Convertible Preferred Stock

On August 28, 2015, the Company filed the Certificate of Designation of Preferences, Rights and Limitations of Series B Convertible Preferred Stock (the “Certificate of Designation”) with the Delaware Secretary of State. The Certificate of Designation creates the Series B Convertible Preferred Stock and fixes the rights, preferences, powers, restrictions and limitations of the Series B Convertible Preferred Stock. The Series B Convertible Preferred Stock is a component of the Units being offered pursuant to the Offering, Units that could be issued upon exercise by the Underwriter of the Unit Purchase Option described in Item 1.01 above and also part of the Exchange Units described in Item 3.02 above.

Each share of Series B Convertible Preferred Stock is convertible into one share of Common Stock (subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events) on the six month anniversary of the Issuance Date or on the date of an Early Separation. In addition, the Series B Convertible Preferred Stock will automatically convert into shares of common stock upon the occurrence of a Fundamental Transaction, subject to the beneficial ownership limitation discussed below. A “Fundamental Transaction” means that (i) the Company shall, directly or indirectly, in one or more related transactions, (1) consolidate or merge with or into (whether or not the Company is the surviving corporation) any other person unless the shareholders of the Company immediately prior to such consolidation or merger continue to hold more than 50% of the outstanding shares of voting stock after such consolidation or merger, or (2) sell, lease, license, assign, transfer, convey or otherwise dispose of all or substantially all of the properties and assets of the Company and its subsidiaries, taken as a whole, to any other person, or (3) allow any other person to make a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding shares of voting stock of the Company (not including any shares of voting stock of the Company held by the person or persons making or party to, or associated or affiliated with the persons making or party to, such purchase, tender or exchange offer), or (4) consummate a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with any other person whereby such other person acquires more than 50% of the outstanding shares of voting stock of the Company (not including any shares of voting stock of the Company held by the other person or other persons making or party to, or associated or affiliated with the other persons making or party to, such stock or share purchase agreement or other business combination), or (ii) any “person” or “group” (as these terms are used for purposes of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder), other than a Permitted Holder, is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% of the aggregate ordinary voting power represented by issued and outstanding voting stock of the Company. The term Permitted Holders means Josh Kornberg, Atlantic Partners Alliance and SOK Partners, LLC and each of their respective affiliates.

The Series B Convertible Preferred Stock will not be 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. For purposes of the limitation described in this paragraph, beneficial ownership and all determinations and calculations are determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.

The Series B Convertible Preferred Stock has no voting rights, except that the holders of shares of a majority of the Series B Convertible Preferred Stock will be required to effect or validate any amendment, alteration or repeal of any of the provisions of the Certificate of Designation that materially adversely affects the powers, preferences or special rights of the Series B Convertible Preferred Stock, whether by merger or consolidation or otherwise, subject to certain exceptions set forth in the Certificate of Designations.

With respect to payment of dividends and distribution of assets upon liquidation or dissolution or winding up of the Company, the Series B Convertible 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 Convertible Preferred Stock.

Cancellation of the Company’s Series A Preferred Stock.

On August 31, 2015, the Company filed the Termination Certificate for Series A Convertible Preferred Stock (the “Termination Certificate”) with the Delaware Secretary of State. After the cancellation of the Series A Convertible Preferred Stock pursuant to the Unit Exchange described in Item 3.02 above, there were no shares of Series A Convertible Preferred Stock outstanding. The Termination Certificate removed the Series A Convertible Preferred Stock from the Company’s authorized share capital, rendered the Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible Preferred Stock (the “Series A Certificate of Designation”) null and void and eliminated all matters set forth in the Series A Certificate of Designation with respect to the Series A Convertible Preferred Stock from the Certificate of Incorporation of the Company. Pursuant to the Termination Certificate, the authorized shares of Series A Convertible Preferred Stock in the Series A Certificate of Designation resumed the status of authorized but unissued 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.

Other Events

As a result of the consummation of the Offering and the Unit Exchange on August 31, 2015, the Company issued a total of 1,895,010 Units (1,666,667 Units sold in the Offering and 228,343 Exchange Units issued in the Unit Exchange), comprised of a total of aggregate of 1,895,010 shares of Common Stock, 1,895,010 shares of Series B Preferred Stock and 7,580,040 Series A Warrants.

As of such date, the Underwriter had the right to purchase an additional 250,000 Units pursuant to its overallotment option under the Underwriting Agreement and 83,333 Units pursuant to the Unit Purchase Option.

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.

In January 2014 the Company issued 4,336 shares of common stock to the former CEO at $1.25 per share upon his exercising options.

In January through March 2014, 9 warrant holders exercised warrants through a cashless exercise for a total of 15,442 shares of common stock.

In January and February 2014 the Company issued warrants to purchase 21,538 shares pursuant to a February 4, 2014 private placement whereby the Company issued 20,550 shares of Series A Convertible Preferred Stock raising gross proceeds of $2,055,000. The warrants are at an exercise price of $24.38.

In February 2014 the Company issued a warrant to purchase 1,482 shares of common stock at an exercise price of $20.25 to a major shareholder Dr. Samuel Herschkowitz. The warrant is in consideration for a bridge loan extended in December 2013 that has been paid in February 2014.

On March 31, 2014, the Company issued dividends to the Purchasers of the Preferred Shares as described above. The dividends are at an annual rate of 6% of the stated value of the Preferred Shares paid on a quarterly basis in the form of common stock per a stipulated $19.50 per share. As a result 970 shares of common stock were issued to 16 holders of Preferred Shares.

In March 2014, the Company issued 4,444 shares of common stock to a warrant holder for a partial cash exercise at $11.25 per share; issued 3,333 shares to the holder via the cashless exercise of the remainder of the warrant.

In June 2014, the Company issued 3,725 shares of common stock to a warrant holder exercising cashless warrants.

On June 30, 2014, the Company issued dividends to the Purchasers of the Preferred Shares as described above. The dividends are at an annual rate of 6% of the stated value of the Preferred Shares paid on a quarterly basis in the form of common stock per a stipulated $19.50 per share. As a result 1,561 shares of common stock were issued to 16 holders of Preferred Shares.

On June 30, 2014, the Company issued a warrant to purchase 5,431 shares of common stock at an exercise price of $12.38 to SOK Partners, LLC, in consideration for a bridge loan in the form of convertible notes. On September 9, 2014 the Resale Registration Statement went into effect. The convertible note agreement provided an immediate approximately 11% reduction to the warrant agreement. Therefore, the warrant has been adjusted to purchase 4,831 shares of common stock at an exercise price of $12.38 to SOK Partners, LLC in consideration for a bridge loan.

In July 2014, the Company issued warrants to purchase 28,986 shares of common stock at an exercise price of $12.38 to two lenders in consideration for a bridge loan in the form of convertible notes. The shares above reflect approximately an 11% reduction resulting from the Resale Registration Statement that went effective September 9, 2014.

In August 2014, the Company issued warrants to purchase 61,539 of common stock at an exercise price of $24.38 to the Purchasers of the Preferred Shares. The Securities Purchase Agreement with the Preferred Shareholders stipulated that if the Company was not listed on either the NASDAQ Stock Market, the New York Stock Exchange or the NYSE MKT within 180 days of closing the agreement then warrants to purchase the above additional shares would be issued in aggregate to the Preferred Shareholders.

In August and September 2014, the Company issued warrants to purchase 37,440 shares of common stock at an exercise price of $12.38 to four lenders in consideration for a bridge loan in the form of convertible notes. The shares above reflect the approximate 11% reduction resulting from the Resale Registration Statement that went effective September 9, 2014.

On September 30, 2014, the Company issued dividends to the Purchasers of the Preferred Shares as described above. The dividends are at an annual rate of 6% of the stated value of the Preferred Shares paid on a quarterly basis in the form of common stock per a stipulated $19.50 per share. As a result 1,561 shares of common stock were issued to 16 holders of Preferred Shares.

In November 2014, the Company issued 13,700 shares of common stock, par value $0.01, in escrow for debt settlement.

On December 31, 2014, the Company issued dividends to the Purchasers of the Preferred Shares as described above. The dividends are at an annual rate of 6% of the stated value of the Preferred Shares paid on a quarterly basis in the form of common stock per a stipulated $19.50 per share. As a result 1,559 shares of common stock were issued to 16 holders of Preferred Shares.

For grants of stock options and warrants in 2014 the Company used a 1.44% to 2.75% risk-free interest rate, 0% dividend rate, 59% to 66% volatility and estimated terms of 5 to 10 years. Value computed using these assumptions ranged from $3.2006 to $13.9195 per share.

In January 2015, the Company issued a dividend adjustment to the Purchasers of the Preferred Shares as described above. Certain previous dividends paid were calculated with an exercise price of $19.50 per share, but should have been calculated at $9.75 per share. As a result 3,122 shares of common stock were issued to 16 holders of Preferred Shares.

On March 31, 2015, the Company issued dividends to the Purchasers of the Preferred Shares as described above. The dividends are at an annual rate of 6% of the stated value of the Preferred Shares paid on a quarterly basis in the form of common stock per a stipulated $9.75 per share. As a result 3,121 shares of common stock were issued to 16 holders of Preferred Shares.

On June 30, 2015, the Company issued dividends to Purchases of the Preferred Shares as described above. The dividends are at an annual rate of 6% of the stated value of the Preferred Shares paid on a quarterly basis in the form of common stock per a stipulated $9.75 per share. As a result 3,121 shares of common stock were issued to 16 holders of Preferred Shares.

For grants of stock options and warrants in 2015 the Company used a 1.63% to 2.35% risk-free interest rate, 0% dividend rate, 59% to 66% volatility and estimated terms of 5 to 10 years. Value computed using these assumptions ranged from $0.2750 to $5.5695 per share.
