Issuance of Convertible Notes and Series of Warrants	13. Issuance of Convertible Notes and Series of Warrants On September 27, 2010, the Company issued and sold to certain investors 892 units at a purchase price of $10,000 per unit, resulting in gross proceeds of $8.92 million to the Company. Each unit consists of a three-year, 9% convertible promissory note in the principal amount of $10,000 (the “9% Convertible Note”) and a three-year Series F common stock purchase warrant (the “Series F Warrant”), to purchase 1,250 shares of the Company’s common stock at an exercise price of $2.50 per share. The 9% Convertible Notes are payable at an interest rate of 9% per annum, payable semiannually in arrears on the last day of the first and third calendar quarters (i.e., March 31 and September 30) commencing March 31, 2011 and mature on September 26, 2013 (the “Maturity Date”). Except for the secured Indebtedness (as defined in the 9% Convertible Note) of the Company and its subsidiaries in existence on September 27, 2010, the obligations of the Company under the 9% Convertible Notes will rank senior with respect to all existing indebtedness of the Company as of September 27, 2010 and to any and all Indebtedness incurred thereafter. The 9% Convertible Notes are also convertible into shares of common stock at any time prior to the Maturity Date at $2.00 per share, which conversion price is subject to weighted average and other customary anti-dilution protections. At any time after September 26, 2011, the Company may redeem all but not less than all of the outstanding principal amount of any 9% Convertible Notes by payment of 108% of the outstanding principal amount of the 9% Convertible Notes, together with accrued but unpaid interest. The 9% Convertible Notes contain customary affirmative and negative covenants. The 9% Convertible Notes also contain customary events of default, upon which the holders of the 9% Convertible Notes may declare all outstanding 9% Convertible Notes to be due and payable immediately. The Series F Warrants issued in connection with the private placement in September 2010 entitle the investors to purchase an aggregate of 1,115,000 shares of common stock at an initial exercise of $2.50 per share, which exercise price is subject to the customary weighted average and stock based anti-dilution protection. The Series F Warrants may be exercised in a cash or cashless way at any time upon the election of the holders until September 26, 2013. Placement Agent Fee The Company paid a cash commission of $713,600, which is equal to 8% of the gross proceeds of the financing to the placement agent. In addition, the Company issued Series F Warrants to the designees of the placement agent to purchase an aggregate of 312,200 shares of common stock of the Company at an exercise price of $2.50 per share, as partial compensation for services provided by them in connection with the private placement. Make Good Escrow Agreement On September 27, 2010, the Company, a major shareholder of the Company, Global Rock, Euro Pacific Capital, Inc. and Escrow, LLC entered into a make good escrow agreement (the “Make Good Escrow Agreement”). Pursuant to the Make Good Escrow Agreement, Global Rock agreed to place a total of 669,000 shares of common stock held by it, which is equal to 15% of the amount of shares of common stock issuable upon conversion of the 9% Convertible Notes (the “Make Good Shares”), into escrow to secure certain make good obligations of the Company. In the event that the combined net sales of the Company of both of the fiscal years ending March 31, 2011 and 2012 is less than $125 million, Global Rock will transfer the Make Good Shares to the investors, on a pro rata basis to the extent of shortfall of the actual net sales achieved compare to the guaranteed net sales of $125 million for no additional consideration. As of June 30, 2011, it is probable that the guaranteed net sales of $125 million for fiscal years ending March 31, 2011 & 2012 may not be achieved. The estimated fair value as of June 30, 2011 of the 266,390 shares expected to be delivered is $218,304 and is reflected as Registration penalties and make good provision payable on the balance sheet as of June 30, 2011. The fair value of Make Good Escrow Agreement will be analyzed every period end using a probability weighted assessment method and adjusted if necessary. Registration Rights Agreement In connection with the private placement of September 2010, the Company and the investors entered into a registration rights agreement (the “Registration Rights Agreement”), pursuant to which, the Company granted registration rights to holders of registrable securities, which include (i) the shares of common stock issuable upon the conversion of the 9% Convertible Notes, (ii) the Make Good Shares, as applicable, (iii) the shares of common stock issuable upon the exercise of Series F Warrants issued to the investors and the placement agent, and (iv) any securities issued or issuable upon any stock split, dividend or other distribution, recapitalization or similar event, or any price adjustment as a result of such stock splits, reverse stock splits or similar events with respect to any of the securities referenced in (i) – (iii) above. Pursuant to the Registration Rights Agreement, the Company is required to file a registration statement on Form S-1 (the “Registration Statement”), within 30 days after the closing of the private placement, or the Closing, and cause the Registration Statement to be declared effective by the Securities and Exchange Commission with 180 days after the Closing. The Company may be subject to liquidated damages in an amount up to 8% ($713,600) of the aggregate investment amount paid by the investors in the private placement if it is unable to file, obtain and maintain effectiveness of the Registration Statement as required by the Registration Rights Agreement by March 27, 2011. The Company filed the Registration Statement on October 27, 2010 and it is effective on August 8, 2011. As of June 30, 2011, the Company has accrued a registration penalty of $388,452 and is reflected as Registration penalties and make good provision payable on the balance sheet as of June 30, 2011. Closing Escrow Agreement On September 27, 2010, the Company also entered into a closing escrow agreement with the placement agent and the escrow agent (the “Closing Escrow Agreement”), pursuant to which, among other things, the Company has placed a certain amount of cash received from the private placement ($408,090) (the “Holdback Amount”), with the escrow agent, which is sufficient to satisfy the payment to the investors of one semiannual interest payment due on the aggregate principal amount of all 9% Convertible Notes issued in the private placement, which includes accrued interest due on the principal amount of the 9% Convertible Notes from September 27, 2010 through March 31, 2011. If, an event of default (as defined in the 9% Convertible Notes) is declared by the placement agent with respect to a failure by the Company to make a semiannual interest payment to the investors in accordance with the 9% Convertible Notes, the escrow agent will disburse a certain portion of the Holdback Amount to the investors, and within 30 days following the disbursement, the Company will deposit an additional amount equal to the Holdback Amount with the escrow agent to be retained and disbursed. On the Maturity Date or at any time prior to the Maturity Date when 75% of all 9% Convertible Notes have been converted, all remaining funds of the Holdback Amount will be disbursed to the Company. Accounting for Convertible Notes and Series F Common Stock Warrants The 9% Convertible Notes and Series F Warrants (issued to both investors and the placement agent) contain ratchet provision which will reduce the conversion and exercise price, based on a formula, if the Company sells or issues securities at a price lower than the conversion or exercise price. The embedded conversion option of the 9% Convertible Notes and the warrants do not meet the test of being indexed only to the Company’s common stock as defined in ASC 815-40-15 because the formula is not based on the market price. Accordingly, the embedded conversion option and warrants are accounted for as derivative liabilities and are required to be re-measured at the end of every reporting period with the change in fair value in the statement of operations. The 8% placement agent fee and other offering costs totaling $888,180 and the fair value of the Series F warrants issued to the placement agent of $231,929 are accounted for deferred financing fees. The gross proceeds of $8,920,000 are allocated to the fair value of the Series F warrants issued to the investors of $828,319, fair value of the embedded conversion option of $3,487,233, and the carrying value of the convertible notes of $4,604,447. The fair value of the embedded conversion option is calculated using a Cox-Ross-Rubinstein (“CRR”) binomial model with the following assumptions: conversion price of $2.00, risk free interest rate of 0.66%, expected term of 3 years, and a volatility of 130%. The fair value of the warrants is calculated using the CRR binomial model with the following assumptions: exercise price of $2.5 per share, risk free interest rate of 0.66%, expected term of 3 years, and a volatility of 130%. The expected volatility is based on average volatility of five comparable companies in the same industry and the Company’s historical volatility. The value of the embedded conversion option and the warrants are re-measured at June 30, 2011 using the CRR binomial model with the same assumptions as stated above except for a risk free interest rate of 0.54% and volatility of 120%. The decrease in fair value of these derivative liabilities for the three months ended June 30, 2011 totaled $415,031, respectively (Note 15). The initial carrying value of the convertible notes will be accreted to their redemption value of $8,920,000 over the three years term of the convertible notes at an effective interest rate of 34.77 %. Effective interest expense recorded for the three months ended June 30, 2011 is $452,830.
