10. Convertible Notes and Warrant Liabilities

On February 22, 2011 (the “Original Issue Date”), the Company entered into a Securities Purchase Agreement (“Purchase Agreement”) and a 5% Senior Secured Convertible Debenture Agreement (the “Note Agreement”) with GCP IV LLC (the “Investors” or “Holders”) pursuant to which the Company agreed to issue and sell in a private placement to the Investors an aggregate principal amount of $4,000,000 of convertible notes due February 22, 2014 (the “Convertible Notes”) and 40,000,000 warrants, which expire February 22, 2016 (the “Investor Warrants”). Under the terms of the Securities Purchase Agreement, the Company had the opportunity to raise up to an additional $2,000,000 from the Holders of the Convertible Notes in two separate $1,000,000 tranches, based upon meeting certain operational milestones within certain periods of time. The deadline for achieving the operational milestones for the first $1,000,000 tranche expired in February 2012 without the Company achieving such milestones; however, as discussed below, the Investors agreed to waive both the deadline and the achievement of these milestones as a condition for the investment of the first additional $1,000,000 tranche (“Second Tranche”) which was completed on July 2, 2012.

Convertible Notes

The Convertible Notes require payment of interest on the outstanding principal amount, in cash, at the rate of 5% per annum, payable quarterly on January 1, April 1, July 1, and October 1, beginning on the first such date following the Original Issue Date, on each conversion date (for the principal amount then being converted), on each optional redemption date (for the principal amount then being redeemed) and on the maturity date. Interest is calculated on the basis of a 360-day year and accrues daily commencing on the Original Issue Date until payment in full of the outstanding principal, together with all accrued and unpaid interest, liquidated damages and other amounts that may become due in connection with the Convertible Notes, has been made.

The Holders may convert the outstanding principal amount of the Convertible Notes into shares of the Company’s common stock at the conversion price of $0.10 per share (“Conversion Price”). The Conversion Price is subject to adjustment in the event of (a) stock splits, stock dividends, combinations, reclassifications, mergers, consolidations, distributions of assets or evidence of indebtedness, sales or transfers of substantially all assets, share exchanges or similar events, and (b) dilutive issuances of (i) common stock or (ii) common stock equivalents at an effective price per share that is lower than the then Conversion Price.

At any time after February 2012, and upon entering into a change of control transaction or Fundamental Transaction, as defined in the Debenture Agreement, the Company may deliver a notice to the Holders of its irrevocable election to redeem all of the then outstanding principal of the Convertible Notes for cash in an amount equal to the sum of (a) the greater of (i) the outstanding amount of the Convertible Notes divided by the Conversion Price on the date of the mandatory default amount, as defined in the Purchase Agreement, is either (A) demanded or (B) paid in full, whichever has a lower conversion price, multiplied by the Volume Weighted Average Price (“VWAP”) of the date of the mandatory default amount is either (x) demanded or otherwise due or (y) paid in full, whichever has higher VWAP, plus all accrued and unpaid interest, or (ii) 130% of the outstanding principal amount of the Notes, plus 100% of accrued and unpaid interest, and (b) all other amounts, costs, expenses and liquidated damages due under the various agreements covering issuance of the Convertible Notes. Such amount would include the liquidated damages due under the default provision of the Purchase Agreement.

The Company is required to repay, in cash, any outstanding principal amount of the Convertible Notes on February 22, 2014 and is not permitted, except upon entering into a change of control transaction or fundamental transaction as noted above, to prepay any portion of the principal amount without prior written consent of the Holders.

Investor Warrants

On February 22, 2011, in connection with the issuance of the Convertible Notes, the Company issued warrants for the purchase of up to 40,000,000 shares of common stock at the exercise price of $0.15 per share and with an expiration date of February 22, 2016 (the “Warrants”). The following is a summary of the Warrants outstanding as of December 31, 2012:

	Warrants	Exercise Price
Beginning balance — December 31, 2011	40,000,000	$	0.15
Add: Adjustments (pursuant to warrants agreement)	—	n/a
Less: Exercised	—	n/a
Ending balance — December 31, 2012	40,000,000	$	0.15

The Warrants are exercisable in cash to purchase shares of the Company’s common stock (the “Warrant Shares”). The Exercise Price may be paid pursuant to a cashless exercise provision if the Warrant Shares have not been registered within six months after the Warrants are issued. The Exercise Price of the Warrants shall be adjusted in the event of (a) stock splits, stock dividends, combinations, reclassifications, mergers, consolidations, distributions of assets or evidence of indebtedness, sales or transfers of substantially all assets, share exchanges or similar events, and (b) dilutive issuances of (i) common stock or (ii) common stock equivalents at an effective price per share that is lower than the then Exercise Price.

In connection with a Fundamental Transaction, as defined in the Purchase Agreement, that is an all-cash transaction, the Company shall have the right to purchase from the Holders all, but not less than all, of the unexercised portion of the Warrants by paying in cash to the Holders an amount equal to 30% of the Exercise Price multiplied by the number of shares of Common Stock for which the Warrants are exercisable immediately prior to such change of control transaction.

Features of the 2012 Tranche 2 Amendment

On July 2, 2012, the Company entered into an Amendment and Waiver to Securities Purchase Agreement (the “Amendment and Waiver”) to amend our Securities Purchase Agreement with the Investors. Under the Amendment and Waiver agreement the Company agreed to issue and sell in a private placement to the Investors an aggregate principle amount of $1,000,000 (the “Second Tranche”) of 5% Senior Secured Convertible Debentures of the Company (the “Second Convertible Notes”), warrants to purchase up to 10,000,000 shares of common stock at an initial exercise price of $0.15 per share (the “$0.15 Warrants”) and warrants to purchase up to 10,000,000 shares of common stock at an initial exercise price of $0.25 per share (the “$0.25 Warrants” and together with the $0.15 Warrants, the “2012 Warrants”).

The Second Tranche Convertible Notes

The Second Tranche Convertible Notes contains the same terms as the original Convertible Notes and requires payment of interest at the rate of 5% per annum, payable quarterly and mature on July 2, 2015. The Second Tranche Convertible Notes provide the Investors the option at any time prior to the repayment of the notes to convert any portion of the outstanding Second Tranche balance into fully-paid and non-assessable restricted shares of common stock of the Company at an initial conversion price of $0.10 per share (the “Conversion Price”).

The Convertible Notes include an adjustment close providing that if the Company issues additional shares of common stock prior to the repayment of the Second Tranche at a price per share less than the effective conversion price of the Second Tranche Convertible Notes, the conversion price will, subject to certain exceptions, be reduced to an amount equal to the price per share paid or payable for the common stock of the Company in such subsequent issuance or deemed subsequent issuance. The Conversion price is subject to adjustments in the event of (a) stock splits, stock dividends, combinations, dividends, rights offerings and mergers of sales of assets or similar events and (b) dilutive issuances of (i) common stock or (ii) common stock equivalents at an effective price per share that is lower than the then Conversion Price.

The Second Tranche Convertible Notes and the Purchase Agreement covering both are secured by a security interest in all assets of the Company and its subsidiaries and all such obligations are guaranteed jointly and severally by the Company’s Subsidiaries. The Second Tranche Convertible Notes also contain non-financial covenants which limit the Company and its subsidiaries from incurring subsequent indebtedness, incur liens, amend organizational documents, repurchasing or repaying other debt, paying cash dividends and entering into affiliate transactions.

The Second Tranche Convertible Notes may be redeemed at the option of the Company on the same terms as the Convertible Notes only in connection with a change of control or other fundamental transaction of the Company and subject to the satisfaction of other conditions including, without limitation, that the shares issuable upon conversion of the debentures are freely tradable and that there is no event of default.

The 2012 Warrants

On July 2, 2012, the Company issued warrants for the purchase of up to 20,000,000 shares of common stock with five year terms. The warrants were issued to allow the Investors to purchase up to 10,000,000 shares of common stock at an initial purchase price of $0.15 per share and the remaining 10,000,000 shares of common stock at an initial purchase price of $0.25 per share. The terms of the 2012 Warrants are identical to those of the Warrants, except that the 2012 Warrants are exercisable for a period of five years from the date of issuance and contain different exercise prices. The following is a summary of the 2012 Warrants outstanding as of December 31, 2012:

$0.15 Warrants	Warrants	Exercise Price
Beginning balance at December 31, 2011	—	$	—
Add: Second Tranche Agreement	10,000,000	0.15
Add: Adjustments (pursuant to warrants agreement)	—	n/a
Less: Exercised	—	n/a
Ending balance at December 31, 2012	10,000,000	$	0.15

$0.25 Warrants	Warrants	Exercise Price
Beginning balance at December 31, 2011	—	$	—
Add: Second Tranche Agreement	10,000,000	0.25
Add: Adjustments (pursuant to warrants agreement)	—	n/a
Less: Exercised	—	n/a
Ending balance at December 31, 2012	10,000,000	$	0.25

The 2012 Warrants are exercisable in cash to purchase shares of the Company’s common stock. The exercise price may be paid pursuant to a cashless exercise provision if the 2012 Warrants have no effective registration statement registering the shares underlying the warrants by surrendering warrant shares having a value equal to the exercise price of the portion of the warrants being exercised. The exercise price of the 2012 Warrants shall be adjusted in the event of (a) stock splits, stock dividends, combinations, rights offerings, mergers or sales of assets or similar events, and (b) dilutive issuances of (i) common stock or (ii) common stock equivalents at an effective price per share that is lower than the exercise price.

The 2012 Warrants provide that the 2012 Warrants may be purchased at the option of the Company only in connection with a change in control of the Company that is an all-cash transaction. The purchase price is 30% of the then effective exercise price of the warrants multiplied by the number of common shares for which the 2012 Warrants are then exercisable.

Accounting for the Convertible Notes, Tranche Two Convertible Notes, Investor Warrants and 2012 Warrants

Investor Warrants and 2012 Warrants

In June 2008, the FASB issued ASC 815-40-15 (formerly EITF 07-5, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock), which was effective for the Company in 2009. This issued guidance requires that derivative instruments be evaluated for certain contingencies and anti-dilution provisions that would affect their equity classification as a derivative under ASC 815, Derivatives and Hedging (ASC 815) and requires the instruments to be classified as liabilities and reported at fair value.

Upon issuance, the Investor Warrants and 2012 Warrants were not considered indexed to the Company’s own stock and therefore are required to be accounted for as freestanding derivative instruments and classified as a liability. As a result, the Investor Warrants and 2012 Warrants were recorded as a liability at fair value as of December 31, 2012 with subsequent changes in fair value recorded in the consolidated statement of operations.

Convertible Notes and Tranche Two Convertible Notes

The Company has determined that the Convertible Notes and Tranche Two Convertible Notes constitute a hybrid instrument that has the characteristics of a debt host contract containing several embedded derivative features that would require bifurcation and separate accounting as a derivative instrument pursuant to the provisions of ASC 815. The Company has identified all of the derivatives associated with the February 22, 2011 financing and July 2, 2012 additional financing. As permitted under ASC 825-10-10 — Financial Instruments, as it relates to the fair value option, the Company has elected, as of February 22, 2011 and July 2, 2012, to measure the Convertible Notes and the Tranche Two Convertible Notes in their entirety at fair value with changes in fair value recognized in the Consolidated Statement of Operations as either a gain or loss until the notes are settled. As such, the Company has appropriately valued the embedded derivatives as a single hybrid contract together with the Convertible Notes and Tranche Two Convertible Notes. This election was made by the Company after determining the aggregate fair value of the Convertible Notes and Tranche Two Convertible Notes to be more meaningful in the context of the Company’s financial statements than if separate fair values were assigned to each of the multiple embedded instruments contained in the Convertible Notes Tranche Two Convertible Notes.

Convertible Notes and Investor Warrants

Upon issuance of the Convertible Notes, the Company allocated the proceeds received to the Convertible Notes and Investor Warrants on a relative fair value basis. As a result of such allocation, the Company determined the initial carrying value of the Notes to be $3,208,000. The Notes were immediately marked to fair value, resulting in a derivative liability in the amount of $3,677,000. As of December 31, 2012 and 2011, the Convertible Notes have been marked to fair value resulting in a derivative liability of $6,510,000 and $5,327,000, respectively. The net charge to other income (expense) was expense of $918,000 and $1,894,000 in the years ended December 31, 2012 and 2011, respectively. The debt discount in the amount of $792,000 (resulting from the allocation of proceeds) is being amortized to interest expense using the effective interest method over the expected term of the Convertible Notes. The Company amortized $265,000 and $225,000 in the years ended December 31, 2012 and 2011, respectively, which is a component of interest expense.

Upon issuance, the Company allocated $792,000 of the initial proceeds to the Investor Warrants and immediately marked them to fair value resulting in a derivative liability of $908,000. As of December 31, 2012 and 2011, the Investor Warrants have been marked to fair value resulting in a derivative liability of $2,000,000 and $1,600,000, respectively. The charge to other income (expense) for the years ended December 31, 2012 and 2011 was expense of $918,104 and $808,000, respectively.

Second Tranche Convertible Notes and 2012 Warrants

Upon issuance of the Second Tranche Convertible Notes, the Company allocated the proceeds received to the Second Tranche Convertible Notes and 2012 Warrants on a relative fair value basis. As a result of such allocation, the Company determined the initial carrying value of the Second Tranche Convertible Notes to be $417,000. The Second Tranche Convertible Notes were immediately marked to fair value, resulting in a derivative liability in the amount of $2,073,000. As of December 31, 2012, the Second Tranche Convertible Notes have been marked to fair value resulting in a derivative liability of $1,588,000. The net charge to other income (expense) was a loss of $1,105,000 for the year ended December 31, 2012. The debt discount in the amount of $583,000 (resulting from the allocation of proceeds) is being amortized to interest expense using the effective interest method over the expected term of the Convertible Notes. The Company amortized $66,000 and $0 in the years ended December 31, 2012 and 2011, respectively, which is a component of interest expense.

Upon issuance of the 2012 Warrants, the Company allocated $583,000 of the initial proceeds to the 2012 Warrants and immediately marked them to fair value resulting in a derivative liability of $2,900,000. As of December 31, 2012, the 2012 Investor Warrants have been marked to fair value resulting in a derivative liability of $1,800,000. The charge to other income (expense) for the year ended December 31, 2012 was expense of $1,100,000.

The Company records the fair value of Convertible Notes and Investor Warrants as long term liabilities.

Financing Costs

Financing costs include costs associated with obtaining the February 22, 2011 financing. Financing costs totaling $530,000 have been recorded in other income (expense) in the year ended December 31, 2011, $135,000 of which were recorded in prepaid expenses and other current assets at December 31, 2010 and expensed upon closing of the transaction in February 2011.

The Company incurred financing costs associated with obtaining the July 2, 2012 financing which totaled $80,000 and were recorded in other income (expense) in the year ended December 31, 2012.

Valuation — Methodology and Significant Inputs Assumptions

Fair values for the Company’s derivatives and financial instruments are estimated by utilizing valuation models that consider current and expected stock prices, volatility, dividends, market interest rates, forward yield curves and discount rates. Such amounts and the recognition of such amounts are subject to significant estimates that may change in the future. The methods and significant inputs and assumptions utilized in estimating the fair value of the Warrant Liabilities and Convertible Notes are discussed below. Each of the measurements is considered a Level 3 measurement as a result of at least one significant unobservable input.

Warrant Liabilities

A Black-Scholes-Merton option-pricing model, with dilution effects, was utilized to estimate the fair value of the Warrant Liabilities as of February 22, 2011, December 31, 2011 and December 31, 2012. This model is widely used in estimating value of European options dependent upon a non-paying dividend stock and fixed inputs. This model is subject to the significant assumptions discussed below and requires the following key inputs with respect to the Company and/or instrument:

Input	February 22, 2011			December 31, 2011			December 31, 2012
Stock Price	$	0.0755		$	0.1075		$	0.15

Dividend Rate	0		%	0		%	0		%
Outstanding Shares of Common Stock	30,351,092			30,351,092			32,434,430

2012 Warrants

$0.15 Warrants

A Black-Scholes-Merton option-pricing model, with dilution effects, was utilized to estimate the fair value of the $0.15 Warrants as of July, 2, 2012 and December 30, 2012.

Input	July 2, 2012			December 31, 2012
Stock Price	$	0.20		$	0.15

Outstanding Shares of Common Stock	30,976,092			32,434,430

$0.25 Warrants

A Black-Scholes-Merton option-pricing model, with dilution effects, was utilized to estimate the fair value of the $0.25 Warrants as of July, 2, 2012 and December 31, 2012.

Input	July 2, 2012			December 31, 2012

Convertible Notes

A binomial lattice model was utilized to estimate the fair value of the Convertible Notes as of February 22, 2011, December 31, 2011 and December 31, 2012. The binomial model considers the key features of the Convertible Notes, as noted above, and is subject to the significant assumptions discussed below. First, a discrete simulation of the Company’s stock price, without effects of dilution due to the conversion feature, was conducted at each node and throughout the expected life of the instrument. Second, a discrete simulation of the Company’s stock price, with effects of dilution due to the conversion feature, was conducted at each node and throughout the expected life of the instrument. Third, based upon the simulated stock price with dilution effect, an analysis of the higher position of a conversion position, redemption position, or holding position (i.e. fair value of the respective future nodes value discounted using the applicable discount rate) was conducted relative to each node until a final fair value of the instrument is conducted at the node representing the measurement date. This model requires the following key inputs with respect to the Company and/or instrument:

Input	February 22, 2011			December 31, 2011			December 31, 2012
Stock Price	$	0.0755		$	0.1075		$	0.15
Strike Price	$	0.10		$	0.10		$	0.10
Expected remaining term (in years)	3.00			2.15			1.15

Dividend Rate	0		%	0		%	0		%
Outstanding Shares of Common Stock	30,351,092			30,351,092			32,434,430
Effective discount rate	20.3		%	13.2		%	13.1		%
Probability of forced redemption	20		%	20		%	20		%

Second Tranche Convertible Notes

A binomial lattice model was utilized to estimate the fair value of the Second Tranche Convertible Notes. The binomial model considers the key features of the Second Tranche Convertible Notes, as noted above, and is subject to the significant assumptions discussed below. First, a discrete simulation of the Company’s stock price, without effects of dilution due to the conversion feature, was conducted at each node and throughout the expected life of the instrument. Second, a discrete simulation of the Company’s stock price, with effects of dilution due to the conversion feature, was conducted at each node and throughout the expected life of the instrument. Third, based upon the simulated stock price with dilution effect, an analysis of the higher position of a conversion position, redemption position, or holding position (i.e. fair value of the respective future nodes value discounted using the applicable discount rate) was conducted relative to each node until a final fair value of the instrument is conducted at the node representing the measurement date. This model requires the following key inputs with respect to the Company and/or instrument:

Input	July 2, 2012			December 31, 2012
Stock Price	$	0.20		$	0.15
Exercise Price	$	0.10		$	0.10
Expected remaining term (in years)	3			2.50
Stock Volatility	100		%	100		%
Risk-Free Rate	0.39		%	0.31		%
Dividend Rate	0		%	0		%
Outstanding Shares of Common Stock	30,976,092			32,434,430
Effective discount rate	10		%	13.2		%
Probability of forced redemption	20		%	20		%

The following are significant assumptions utilized in developing the inputs:

· The Company’s common stock shares are traded on the OTC Bulletin Board and, accordingly, the stock price input is based upon bid prices as of the valuation dates due to the extremely thin trading volume, broker-driven market (vs. exchange market) and the wide bid/ask spread as of the valuation date;

· The expected future stock prices of the Company’s stock were modeled to include the effect of dilution upon conversion of the instruments to shares of common stock;

· Stock volatility was estimated by considering (i) the annualized monthly volatility of the Company’s stock price during the historical period preceding the respective valuation dates and measured over a period corresponding to the remaining life of the instruments (monthly data set is more relevant given the extremely thin trading volume of the Company’s common stock) and (ii) the annualized daily volatility of comparable companies’ stock price during the historical period preceding the respective valuation dates and measured over a period corresponding to the remaining life of the instrument. Historic prices of the Company and comparable companies’ common stock were used to estimate volatility as the Company did not have traded options as of the valuation dates;

· Based upon the Company’s historical operations and management’s expectations for the foreseeable future, the Company’s stock was assumed to be a non-dividend-paying stock;

· The risk-free interest rate is based on the U.S. Treasury Yield curve in effect as of the valuation date for the expected term;

· With respect to the Convertible Notes and Second Tranche Convertible Notes, the Company is expected to pay all accrued interest due to the Holders on each Interest Payment Date;

· With respect to the Convertible Notes and Second Tranche Convertible Notes, based upon management’s expectations for a change of control or fundamental transaction to occur prior to the maturity date of the Convertible Notes and Second Tranche Convertible Notes, a low probability of a forced redemption;

· Upon a change of control redemption, the change of control redemption amount shall equal to the sum of:

I. the greater of:

(i) the outstanding amount of the debt divided by the Conversion Price on the date of the mandatory default amount is either (A) demanded or (B) paid in full, whichever has a lower conversion price, multiplied by the VWAP of the date of the mandatory default amount is either (x) demanded or otherwise due or (y) paid in full, whichever has higher VWAP, plus all accrued and unpaid interest, or

(ii) 130% of the outstanding principal amount of the debt, plus 100% of accrued and unpaid interest, and
