NOTE 7 - Convertible Notes Payable

The “February 2012 Notes”

On February 24, 2012, we entered into a Securities Purchase Agreement with OPKO Health Inc. pursuant to which we sold a 10% secured convertible promissory note in the aggregate principal amount of $1,700,000 due two years from the date of issuance and issued warrants to purchase 8,500,000 shares of the our common stock, at an exercise price of $0.40 per share, for gross proceeds of $1,700,000.

On February 28, 2012 and February 29, 2012, we entered in a Securities Purchase Agreement with two additional buyers pursuant to which we sold an additional $600,000 aggregate principal amount of notes and issued warrants to purchase an additional 3,000,000 shares of our common stock, at an exercise price of $0.40 per share, for gross proceeds of $600,000, on the same terms as the notes and warrants issued to OPKO as described above.

In connection with the sale of the notes and the warrants, the Company and the collateral agent for the buyers entered into a Pledge and Security Agreement pursuant to which all of our obligations under the notes are secured by a first priority perfected security interest in all of our tangible and intangible assets, including all of our ownership interest in our subsidiaries.

The entire principal amount and any accrued and unpaid interest on the notes is due and payable in cash on the maturity date set forth in the notes.  The notes bear interest at the rate of 10% per annum.  The notes are convertible into shares of our common stock at an initial conversion price of $0.20 per share, subject to adjustment.  We may prepay any outstanding amount due under the notes, in whole or in part, prior to the maturity date.  The notes are subject to certain “Events of Defaults” which could cause all amounts due and owing thereunder to become immediately due and payable. Among other things, our failure to pay any accrued but unpaid interest when due, the failure to perform any obligation under the governing transaction documents or if any representation or warranty made by the Company in connection with the governing transaction documents proves to have been incorrect in any material respect constitutes an Event of Default under the governing transaction documents.

The Company is prohibited from effecting a conversion of the notes or exercise of the warrants, to the extent that as a result of such conversion or exercise the holder would beneficially own more than 4.99% (subject to waiver) in the aggregate of the issued and outstanding shares of the Company’s common stock, calculated immediately after giving effect to the issuance of shares of common stock upon conversion of such note or exercise of such warrant, as the case may be.

The warrants are immediately exercisable and expire ten years after the date of issuance.  The warrants have an initial exercise price of $0.40 per share.  The warrants are exercisable in cash or through a “cashless exercise”.  All of the warrants granted with these notes have been exercised.

We determined that the initial fair value of the warrants was $5,221,172 based on the Black-Scholes option pricing model, which we treated as a liability with a corresponding decrease in the carrying value of the notes.  Under authoritative guidance, the carrying value of the notes may not be reduced below zero.  Accordingly, we recorded interest expense of $2,921,172 at the time of the issuance of the notes, which is the excess of the value of the warrants over the allocated fair value of the notes.  The discount related to the notes will be amortized over the term of the notes as interest expense, calculated using an effective interest method.

We determined that, according to ASC 470120-30, a beneficial conversion feature existed based on the intrinsic value of the conversion feature. Due to the fact that the carrying amount of the convertible notes has been reduced to zero, based on the discount allocated from the value of the warrants referred to above, that no beneficial conversion feature is to be recorded. ASC 470-20-30-8 states that if the intrinsic value of the beneficial conversion feature is greater than the proceeds allocated to the convertible instrument, the amount of the discount assigned to the beneficial conversion feature shall be limited to the amount of the proceeds allocated to the convertible instrument.

The “March 2012 Purchase Order Note”

On March 13, 2012, we sold a 10% senior convertible promissory note with a principal amount of $1,000,000 (the “Purchase Order Note”) to an accredited investor for a purchase price of $1,000,000.  The principal amount of the Purchase Order Note is payable in cash on such dates and in such amounts as set forth in the Purchase Order Note, based on the receipt of proceeds from sales to a certain vendor (the “Vendor Proceeds”).  The last date of the scheduled payments under the Purchase Order Note is referred to as the “Final Maturity Date”. All of our obligations under the Purchase Order Note are secured by a first priority security interest in the Vendor Proceeds as defined. The holder of the notes issued in February 2012 agreed to subordinate their security interest in the Vendor Proceeds to the interest of the holder of the Purchase Order Note.

The Purchase Order Note is convertible into shares of our common stock at an initial conversion price of $1.50 per share. The Purchase Order Note bears interest at the rate of 10% per annum.  We may prepay any outstanding amounts owing under the Purchase Order Note, in whole or in part, at any time prior to the Final Maturity Date.  The entire remaining principal amount and all accrued but unpaid or unconverted interest is due and payable on the earliest of (1) the Final Maturity Date, (2) the consummation of a financing by the Company resulting in net proceeds equal to or greater than 1.5 times the remaining outstanding unconverted principal amount and (3) the occurrence of an Event of Default (as defined in the Purchase Order Note).

The Company has not recorded a BCF on the March 201 2 Purchase Order Notes due to the effective conversion price being greater than the fair value of the Company’s stock at the issuance date.

The Company is prohibited from effecting a conversion of the Purchase Order Note, to the extent that as a result of such conversion, the holder would beneficially own more than 4.99% (subject to waiver) in the aggregate of the issued and outstanding shares of the Company’s common stock, calculated immediately after giving effect to the issuance of shares of common stock upon conversion of the Purchase Order Note.

As of March 31, 2013, the Company repaid $600,000 of the Purchase Order Note.

The “April 2012 Working Capital Note”

On April 18, 2012, we sold a 10% senior convertible promissory note with a principal amount of $250,000 (the “Working Capital Note”) to an accredited investor for a purchase price of $250,000.  The principal amount of the Working Capital Note is payable in cash on such dates and in such amounts as set forth in the Working Capital Note based on the receipt of the Vendor Proceeds as defined.  The last date of the scheduled payments under the Working Capital Note is referred to as the “Final Maturity Date”. All of our obligations under the Purchase Order Note are secured by a first priority security interest in the Vendor Proceeds. The buyers of the February 2012 Notes agreed to subordinate their security interest in the Vendor Proceeds to the interest of the holder of the Working Capital Note.

The Working Capital Note is convertible into shares of our common stock at an initial conversion price of $1.50 per share. The Working Capital Note bears interest at the rate of 10% per annum.  We may prepay any outstanding amounts owing under the Working Capital Note, in whole or in part, at any time prior to the Final Maturity Date.  The entire remaining principal amount and all accrued but unpaid or unconverted interest is due and payable on the earliest of (1) the Final Maturity Date, (2) the consummation of a financing by the Company resulting in net proceeds equal to or greater than 1.5 times the remaining outstanding unconverted principal amount and (3) the occurrence of an Event of Default (as defined in the Working Capital Note).

The Company is prohibited from effecting a conversion of the Working Capital Note, to the extent that as a result of such conversion, the holder would beneficially own more than 4.99% (subject to waiver) in the aggregate of the issued and outstanding shares of the Company’s common stock, calculated immediately after giving effect to the issuance of shares of common stock upon conversion of the Working Capital Note.

On September 28, 2012, the holder of the Working Capital Note exchanged such note for the June 2012 Convertible Notes described below.

The “June 2012 Working Capital Notes”

On June 13, 2012, we sold 10% promissory notes with an aggregate principal amount of $200,000 (the “June 2012 Working Capital Notes”) to accredited investors for an aggregate purchase price of $200,000. The principal amount of the June 2012 Working Capital Notes is payable in cash on the date that is the earlier of receipt by the Company of $500,000 or more from any source (other than sales in the ordinary course of business) or three months from the issuance date.

The June 2012 Working Capital Notes bear interest at the rate of 10% per annum. We may prepay any outstanding amounts owing under the June 2012 Working Capital Notes, in whole or in part, at any time prior to the maturity date.

On June 28, 2012, the holders of the June 2012 Working Capital Notes exchanged such notes for the June 2012 Convertible Notes described below.

The “June 2012 Convertible Notes”

On June 28, 2012, we issued 10% convertible promissory notes (the “June 2012 Convertible   Notes”) with an aggregate principal amount of $455,274 and warrants (the “June 2012 Warrants”) to purchase 2,250,000 shares of our common stock at an exercise price of $0.40 per share to the holders of the Working Capital Notes and June 2012 Working Capital Notes with an aggregate amount of principle and accrued interest due as of such date equal to the aggregate principle amount of the June 2012 Convertible   Notes. The Working Capital Notes and June 2012 Working Capital Notes were cancelled.

The June 2012 Convertible Notes bear interest at the rate of 10% per annum and mature two years from their issue date. We may prepay any outstanding amounts owing under the June 2012 Convertible Notes, in whole or in part, at any time prior to the maturity date. The entire remaining principal amount and all accrued but unpaid or unconverted interest is due and payable on the earlier of the Maturity Date or the occurrence of an Event of Default (each as defined in the June 2012 Convertible Notes). The June 2012 Convertible Notes are convertible into shares of our common stock at an initial conversion price of $0.20 per share.

The Company is prohibited from effecting a conversion of the June 2012 Convertible Notes or exercise of the June 2012 Warrants, to the extent that as a result of such conversion or exercise, the holder would beneficially own more than 4.99% (subject to waiver) in the aggregate of the issued and outstanding shares of the Company’s common stock, calculated immediately after giving effect to the issuance of shares of common stock upon conversion of the June 2012 Convertible Note or exercise of the June 2012 warrant, as the case may be.

The June 2012 Warrants are exercisable immediately expire ten years after the date of issuance and have an initial exercise price of $0.40 per share. The June 2012 Warrants are exercisable in cash or through a “cashless exercise”. We determined that the initial fair value of the June 2012 Warrants was $1,036,042 based on the Black-Scholes option pricing model, which we treated as a liability with a corresponding decrease in the carrying value of the June 2012 Convertible Notes.  Under authoritative guidance, the carrying value of the June 2012 Convertible Notes may not be reduced below zero.  Accordingly, we recorded interest expense of $580,768, which is the excess of the value of the June 2012 Warrants over the allocated fair value of the June 2012 Convertible Notes, at the date of the issuance.  The discount related to the June 2012 Convertible Notes will be amortized over the term of the Notes as interest expense, calculated using an effective interest method.

We determined that, according to ASC 470120-30, a beneficial conversion feature existed based on the intrinsic value of the conversion feature. Due to the fact that the carrying amount of the convertible notes has been reduced to zero, based on the discount allocated from the value of the warrants referred to above, that no beneficial conversion feature is to be recorded. ASC 470-20-30-8 states that if the intrinsic value of the beneficial conversion feature is greater than the proceeds allocated to the convertible instrument, the amount of the discount assigned to the beneficial conversion feature shall be limited to the amount of the proceeds allocated to the convertible instrument.

The following table sets forth a summary of all the outstanding convertible promissory notes at March 31, 2013:
