The “March 2011 Warrants”

In March, 2011, the Company issued the March 2011 Warrants to purchase securities of the Company in the Target Transaction Financing as defined in the governing purchase agreement (Note 5).

The March 2011 Warrants may be exercised immediately and expire five years after the date of issue. Each March 2011 Warrant has an initial exercise price of 120% of the price of the securities sold in the Target Transaction Financing (the “Financing Share Price”). The March 2011 Warrant entitles the holder to purchase the number of shares of Common Stock and/or other securities, including units of securities, sold in the Target Transaction Financing equal to the Warrant Coverage (as defined below) (a) multiplied by the principal amount of the Note (the “Purchase Price”) and (b) divided by the Financing Share Price. “Warrant Coverage” means (i) 50% if closed on or prior to 120 days, (ii) 75% if closed after 120 days but before 150 days and (iii) 100% if closed after 150 days after the closing of the Private Placement. The March 2011 Warrant is exercisable in cash or by way of a “cashless exercise” during any period that a registration statement covering the resale of the underlying shares of common stock and/or other securities issuable upon exercise of the March 2011 Warrant, or an exemption from registration is not available. The exercise price of the March 2011 Warrant is subject to a “ratchet” anti-dilution adjustment for a period of one year from the closing of the Private Placement. This adjustment provides that in the event that the Company issues certain securities at a price lower than the then applicable exercise price, the exercise price of the March 2011 Warrant will be immediately reduced to equal the price at which the Company issued the securities.

On February 28, 2012, each holder of March 2011 Warrants entered into a Cancellation Agreement, which provides, among other things, for the cancellation of the March 2011 Warrants. In exchange, the Company issued to the former holders of the March 2011 Warrants a total of 1,000,000 replacement warrants (the “Replacement Warrants”).  The Replacement Warrants may be exercised immediately and expire four years after the date of issue. Each Warrant has an initial exercise price of $0.60 per share, subject to adjustment for certain corporate reorganization transactions.

As of December 31, 2013, a total of 1,000,000 Replacement Warrants remain outstanding, with an exercise price of $0.60 per share

The “September 2011 Warrants”

In connection with the sale of the September 2011 Note, we issued the September 2011 Warrant to purchase certain securities of the Company in the Target Transaction Financing (Note 5).

The September 2011 Warrant may be exercised immediately and expires five years after the date of issue. The September 2011 Warrant has an initial exercise price of the lower of $1.80 and 120% of the per share price in the Target Transaction Financing. The September 2011 Warrant entitles the holder to purchase the number of shares of common stock and/or other securities, including units of securities, sold in the PIPE Offering (as defined in the Warrant) equal to the principal amount of the note issued pursuant to the Securities Purchase Agreement, divided by the lower of $1.50 and the per share price in the PIPE Offering. The September 2011 Warrant is exercisable in cash or, while a registration statement covering the resale of the underlying shares of common stock and/or other securities issuable upon exercise of the September 2011 Warrant, or an exemption from registration, is not available, by way of a “cashless exercise”. The exercise price of the September 2011 Warrant is subject to a “ratchet” anti-dilution adjustment for a period of one year from the issue date of the September 2011 Warrant. This adjustment provides that in the event that the Company issues certain securities at a price lower than the then applicable exercise price, the exercise price of the September 2011 Warrant shall be immediately reduced to equal the price at which the Company issued the securities.

On November 30, 2011, the holder of the September 2011 Note converted the entire principal amount and accrued interest due with respect to the note into 1,018,356 shares of our common stock and the September 2011 Warrant was cancelled. In exchange, we issued to the holder a Replacement Warrant to purchase 500,000 shares of our common stock at an exercise price of $1.00 per share.

On June 28, 2012, the holder of the Replacement Warrant exercised his right to acquire 500,000 shares of our common stock through the cashless exercise feature and we issued to the holder 375,000 shares of our common stock.

The “January 2012 Warrants”

On January 11, 2012 and January 25, 2012, we sold an aggregate of 1,300,000 units (the “Units”) to accredited investors. Each Unit was sold for a purchase price of $0.50 per Unit and consisted of: (i) one share of the Company’s common stock and (ii) a four-year warrant to purchase 650,000 shares of common stock at an exercise price of $1.00 per share, subject to adjustment upon the occurrence of certain events (the “January 2012 Warrants”). The exercise price of the January 2012 Warrants is subject to a “ratchet” anti-dilution adjustment for a period of one year from the closing date of the transaction. The January 2012 Warrants may be exercised on a cashless basis after twelve (12) months from the date of closing if there is no effective registration statement covering the resale of the underlying shares of common stock issuable upon exercise of the warrant. The January 2012 warrants provide the holder with “piggyback registration rights”, which obligate us to register the common shares underlying the warrants upon request of the holders in the event that we decide to register any of our common stock either for our own account or the account of a security holder (subject to certain exceptions).  Based on authoritative guidance, we have accounted for the January 2012 Warrants as liabilities.

As of December 31, a total of 650,000 January 2012 Warrants remain outstanding, with an exercise price of $0.50 per share.

The “February 2012 Warrants”

Based on authoritative guidance, we have accounted for the February 2012 Warrants as liabilities. The liability for the warrants, measured at fair value, based on a Black-Scholes option pricing model, has been offset by a reduction in the carrying value of the related February 2012 Notes.

On April 25, 2012, certain holders February 2012 Warrants exercised their right to acquire 3,000,000 shares of our common stock through the cashless exercise feature and we issued to the holders a total of 2,636,804 shares of our common stock.
