2014 Unit Offerings |
|
From January 31, 2014 to July 10, 2014 we received gross proceeds of $680,000 from accredited investors at a price of $1.00 per unit and issued 680,000 shares of common stock and two-year warrants to purchase 680,000 shares of common stock at an exercise price of $1.25 per share. |
|
The net proceeds of $680,000 were allocated based on the relative fair values of the common stock and the warrants on the dates of issuance. The amount allocated to the fair value of the warrants was $182,473 and the balance of the proceeds of $497,527 was allocated to the common stock. The fair value of the warrants issued was computed using the Black Scholes Option Pricing model using the following assumptions – expected life – 2 years, risk free interest rate – 0.31% to 0.52%, volatility – 76.7% to 97.4%, and an expected dividend rate of 0%. |
|
From August 4 to December 17, 2014 we received gross proceeds of $585,000 from accredited investors at a price of $0.50 per unit and issued 1,170,000 shares of common stock and two-year warrants to purchase 1,170,000 shares of common stock at an exercise price of $0.75 per share. |
|
The net proceeds of $585,000 were allocated based on the relative fair values of the common stock and the warrants on the dates of issuance. The amount allocated to the fair value of the warrants was $221,133 and the balance of the proceeds of $363,867 was allocated to the common stock. The fair value of the warrants issued was computed using the Black Scholes Option Pricing model using the following assumptions – expected life – 2 years, risk free interest rate – 0.41% to 0.64%, volatility – 83.9% to 201.8%, and an expected dividend rate of 0%. |
|
2013 Unit Offerings |
|
On January 25, 2013 we completed a private placement to accredited investors of 105,000 restricted shares of our common stock, at a purchase price of $1.00 per share, for gross proceeds of $105,000. As part of the private placement, the investors were issued three-year warrants to purchase 105,000 shares of our common stock, at an exercise price of $1.50 per share. |

|
The fair value of the warrants issued in our unit private placement was calculated using the Black-Scholes option valuation model with the following assumptions – expected life – 3 years, risk free interest rate – 0.42%, volatility – 346.4%, and an expected dividend rate of 0%. |
|
From April 9 to July 11, 2013 we raised gross proceeds of $871,000 in a unit private placement to accredited investors at a price of $1.50 per unit. Each unit is comprised of one share of common stock and one three-year warrant to purchase common stock at an exercise price of $2.00 per share.

Also included is $10,000 received from a member of our board of directors. We issued an aggregate of 580,667 shares of common stock and warrants to purchase 580,667 shares of common stock at an exercise price of $2.00 per share. |

The amount allocated to the fair value of the warrants was $256,836 and the balance of the proceeds of $504,164 was allocated to the common stock. The fair value of the warrants issued was computed using the Black Scholes Option Pricing model using the following assumptions – expected life – 3 years, risk free interest rate – 0.34% to 0.65%, volatility – 91.4% to 150.3%, and an expected dividend rate of 0%. |
|
From October 10 to December 31, 2013 we received gross proceeds of $650,000 from accredited investors at a price of $1.00 per unit and issued 650,000 shares of common stock and two-year warrants to purchase 650,000 shares of common stock at an exercise price of $1.25 per share. |

|

|
During the year ended December 31, 2013 we issued 48,842 shares of common stock with a fair value of $75,000 to SAM Advisors, LLC. The issuances were based on the closing market prices as of the date of issuance pursuant to our agreement to convert their $12,500 monthly consulting fee to stock at the closing market price on the last business day of each month. SAM Advisors, LLC is an entity controlled by William B. Smith, our chairman and chief executive officer. Effective July 1, 2013 Mr. Smith receives this amount in cash. |
|
During the year ended December 31, 2013 we issued 6,143 shares of common stock with a fair value of $11,250 to Charles Hunt, a member of our board of directors. The issuances were based in the closing market prices as of the date of issuance pursuant to our agreement to convert $3,750 of his monthly consulting fee to stock at the closing market price on the last business day of each month. |
|
2012 Unit Offering Amendments |
|
From January 24 to November 21, 2012 we sold 474,632 units at a subscription price of $3.50 per unit for gross proceeds of $1,661,199 in our unit private placement. Each unit consisted of one share of common stock and a three-year warrant to purchase one share of common stock at an exercise price of $3.75 per share. A total of 474,632 shares of common stock and warrants to purchase 474,632 shares of common stock at an exercise price of $3.75 were issued. |
|
On October 10, 2012 the board of directors reset the exercise price of the $3.75 per share warrants to purchase 474,632 warrants issued from $3.75 per share to $2.00 per share. All other terms and conditions of the warrants remain unchanged. |
|
On January 25, 2013 we amended the terms of the 2012 Unit Offering, reducing the purchase price of the unit to $1.00 and reducing the exercise price of the warrant to $1.50 per share. As a result of the amendment, the Company issued an additional 1,186,567 shares of common stock to those investors and increased the number of shares reserved for issuance upon the exercise of the warrants by 1,186,567. The issuance of the shares under the amendment was considered non-compensatory; therefore, there was no effect on the results of operations. The effect of the issuance was a reallocation of the original gross proceeds among additional paid-in capital accounts attributable to the shares and warrants, based on the relative fair values of the instruments delivered in total, including those issued under the amended terms. As a result of this reduction in price and change in the number of issued shares, the allocation of the net proceeds of $1,425,768 would have resulted in $587,989 being allocated to the warrants and the balance of the proceeds of $837,779 would have been allocated to the common stock. |
