Add: Issued		270,594,093
Less: Exercised		111,803,243

The outstanding warrants at April 30, 2013 have a weighted average exercise price of $0.091 per share and have a weighted average remaining life of 3.25 years.

As of April 30, 2013, the Company has 124,933,402 warrants with a current exercise price of $0.03 and an expiry date of March 31, 2016, 6,041,893 warrants with a current exercise price of $0.03 and an expiry date of July 11, 2016, 27,272,720 warrants with a current exercise price of $0.03 and an expiry date of September 30, 2016, 7,524,145 warrants with a current exercise price of $0.03 and an expiry date of February 2, 2017, 24,565,367 warrants with a current exercise price of $0.03 and an expiry date of August 10, 2017 and 24,999,999 warrants with a current exercise price of $0.03 and an expiry date of December 10, 2017 (215,337,526 warrants in total), which have price protection provisions that allow for the reduction in the current exercise price upon the occurrence of certain events, including the Company’s issuance of common stock or securities convertible into or exercisable for common stock, such as options and warrants, at a price per share less than the exercise price then in effect. For instance, if the Company issues shares of its common stock or options exercisable for or securities convertible into common stock at an effective price per share of common stock less than the exercise price then in effect, the exercise price will be reduced to the effective price of the new issuance. Simultaneously with any reduction to the exercise price, the number of shares of common stock that may be purchased upon exercise of each of these warrants shall be increased proportionately, so that after such adjustment the aggregate exercise price payable for the adjusted number of warrants shall be the same as the aggregate exercise price in effect immediately prior to such adjustment.

The Company’s issuance of the following securities will not trigger the price protection provisions of the warrants described above that were issued in connection with the March 2008 private placement: (a) shares of common stock or standard options to the Company’s directors, officers, employees or consultants pursuant to a board-approved equity compensation program or other contract or arrangement (up to an aggregate amount of 5,608,926, representing 5% of the common stock issued and outstanding immediately prior to March 31, 2008); (b) shares of common stock issued upon the conversion or exercise of any security, right or other instrument convertible or exchangeable into common stock (or securities exchangeable into common stock) issued prior to March 31, 2008; (c) the shares of common stock issued upon exercise of the warrants issued in March 2008; and (d) shares of common stock and warrants in connection with strategic alliances, acquisitions, mergers, and strategic partnerships, the primary purpose of which is not to raise capital, and which are approved in good faith by the Company’s board of directors (up to an aggregate number of 11,217,852, representing 10% of the shares of common stock issued and outstanding immediately prior to March 31, 2008).

An aggregate of 13,333,333 shares of the Company’s common stock were issuable upon conversion of the Series B convertible preferred stock which was issued at the initial closing. On December 10, 2012, the triggering of the price protection features of the Series B convertible preferred stock resulted in a decrease of the conversion price from $0.08 to $0.03 per share and a corresponding increase in the number of common shares underlying the remaining 792 shares of Series B convertible preferred stock as of December 10, 2012 from 9,897,500 to 26,393,333.

Accounting for proceeds from the Series B convertible preferred stock financing

The net cash proceeds from the Series B convertible preferred stock financing were $1,975,000. The proceeds from the financing were allocated first to the warrants that were issued in the financing and second to the make-whole payments. As the assigned fair values were greater than the net cash proceeds from the transaction, the excess was treated as a “deemed dividend” for accounting purposes and was reported on the Company’s consolidated statements of operations for the fiscal year ended July 31, 2012 under the caption “Preferred Stock Dividend”. The calculation methodologies for the fair values of the derivative warrant liability are described in Note 10 – Derivative Liabilities below. The fair values assigned to each component and the calculation of the amount of the deemed dividend are as follows:

Accounting allocation of initial proceeds	July 31, 2012
Net proceeds	$	1,975,000
Derivative warrant liability fair value		(1,811,746	)

An aggregate of 9,375,000 shares of the Company’s common stock were issuable upon conversion of the Series C convertible preferred stock which was issued at the initial closing. On December 10, 2012, the triggering of the price protection features of the Series C convertible preferred stock resulted in a decrease of the conversion price from $0.08 to $0.03 per share and a corresponding increase in the number of common shares underlying the 650 shares of Series C convertible preferred stock as of December 10, 2012 from 8,125,000 to 21,666,666. As of the end of the Company’s fiscal quarter ended January 31, 2013, all of the issued Series C 9% Convertible Preferred Stock had been converted to common stock.

Accounting for proceeds from the Series C convertible preferred stock financing

The net cash proceeds from the Series C convertible preferred stock financing were $725,000. The proceeds from the financing were allocated first to the warrants that were issued in the financing and second to the make-whole payments. As the assigned fair values were greater than the net cash proceeds from the transaction, the excess was treated as a “deemed dividend” for accounting purposes and was reported on the Company’s interim consolidated statements of operations for the quarter ended October 31, 2012 under the caption “Preferred Stock Dividend”. The calculation methodologies for the fair values of the derivative warrant liability and the derivative additional investment rights liability are described in Note 10 – Derivative Liabilities below. The fair values assigned to each component and the calculation of the amount of the deemed dividend are as follows:

Accounting allocation of initial proceeds	October 31, 2012
Net proceeds	$	725,000

Make-whole payments liability		(202,500	)

Series D 9% Convertible Preferred Stock

The Company has authorized 750 shares of Series D 9% Convertible Preferred Stock with a stated value of one thousand ($1,000) per share. Pursuant to a securities purchase agreement dated December 10, 2012, the Company sold an aggregate of 750 shares of Series D convertible preferred stock, as well as accompanying warrants to purchase 24,999,999 shares of common stocks. An aggregate of 24,999,999 shares of the Company’s common stock are issuable upon conversion of the Series D convertible preferred stock which was issued at the initial closing.

Subject to certain ownership limitations, the convertible preferred stock is convertible at the option of the holder at any time into shares of the Company’s common stock at an effective conversion price of $0.03 per share, and will accrue a 9% dividend until December 10, 2015 and, beginning on December 10, 2015 and on each one year anniversary thereafter, such dividend rate will increase by an additional 3%. The dividend is payable quarterly on September 30, December 31, March 31 and June 30, beginning on December 31, 2012 and on each conversion date in cash, or at the Company’s option, in shares of common stock. In the event that the convertible preferred stock is converted prior to December 10, 2015, the Company will pay the holder of the converted preferred stock an amount equal to $270 per $1,000 of stated value of the convertible preferred stock, less the amount of all prior quarterly dividends paid on such converted preferred stock before the relevant conversion date. Such “make-whole payment” may be made in cash or, at the Company’s option, in shares of its common stock. In addition, beginning December 10, 2015, the Company will pay dividends on shares of preferred stock equal to (on an as-if-converted-to-common-stock basis) and in the same form as dividends (other than dividends in the form of common stock) actually paid on shares of the common stock when, and if such dividends are paid. The Company will incur a late fee of 18% per annum on unpaid dividends.

The conversion price of the convertible preferred stock is subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders. The conversion price will also be adjusted if the Company sells or grants any shares of common stock or securities convertible into, or rights to acquire, common stock at an effective price per share that is lower than the then conversion price, except in the event of certain exempt issuances. In addition, the holders of convertible preferred stock will be entitled to receive any securities or rights to acquire securities or property granted or issued by the Company pro rata to the holders of its common stock to the same extent as if such holders had converted all of their shares of convertible preferred stock. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the holders of convertible preferred stock will be entitled to receive, upon conversion of their shares, any securities or other consideration received by the holders of the Company’s common stock pursuant to the fundamental transaction.

The Company may become obligated to redeem the convertible preferred stock in cash upon the occurrence of certain triggering events, including the failure to provide an effective registration statement covering shares of common stock issuable upon conversion of the convertible preferred stock, material breach of certain contractual obligations to the holders of the convertible preferred stock, the occurrence of a change in control of the Company, the occurrence of certain insolvency events relating to the Company, or the failure of the Company’s common stock to continue to be listed or quoted for trading on one or more specified United States securities exchanges or regulated quotation services. Upon the occurrence of certain triggering events, each holder of convertible preferred stock will have the option to redeem such holder’s shares of convertible preferred stock for a redemption price payable in shares of common stock or receive an increased dividend rate of 18% on all of such holder’s outstanding convertible preferred stock.

In conjunction with the issuance of the Series D convertible preferred stock, the Company also issued 24,999,999 warrants to the investors. Subject to certain ownership limitations, the warrants will be exercisable at any time after their date of issuance and on or before the fifth-year anniversary thereafter at an exercise price of $0.03 per share of common stock. The exercise price of the warrants and, in some cases, the number of shares issuable upon exercise, are subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders. The exercise price and number of shares of common stock issuable upon exercise will also be adjusted if the Company sells or grants any shares of common stock or securities convertible into, or rights to acquire, common stock at an effective price per share that is lower than the then exercise price, except in the event of certain exempt issuances. In addition, the warrant holders will be entitled to receive any securities or rights to acquire securities or property granted or issued by the Company pro rata to the holders of its common stock to the same extent as if such holders had exercised all of their warrants. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the warrant holders will be entitled to receive, upon exercise of their warrants, any securities or other consideration received by the holders of the Company’s common stock pursuant to the fundamental transaction. These warrants have been classified as derivative liabilities and are described further in this note above.

Due to the anti-dilution adjustments to the Company’s outstanding Series B and Series C preferred stock, and the various warrants with anti-dilution provisions, which resulted from the issuance of the Series D convertible preferred stock, the Company did not have sufficient authorized Common Stock to issue upon conversion of all of its outstanding preferred stock and exercise of all of its outstanding warrants at the time of issuance of the Series D convertible preferred stock. The investors agreed that the Series D convertible preferred stock and the accompanying warrants issued would not be convertible or exercisable until the Company’s stockholders authorized an amendment to the Company’s Certificate of Incorporation increasing the authorized Common Stock to 1,500,000,000 shares. The December 10, 2012 securities purchase agreement required the Company to obtain such authorization within 120 days after closing. If stockholder approval was not obtained in that time, the investors could require the Company to redeem the preferred stock for cash. The stockholder approval was obtained on March 28, 2013 and a registration statement was subsequently filed which was declared effective by the SEC on April 10, 2013.

As of April 30, 2013, 219 of the Series D convertible preferred stock had been converted to common stock. There were 7,299,999 shares of common stock issued upon the conversion of the Series D convertible preferred stock and 2,145,989 shares of common stock issued as “make-whole payments” on such conversions.

Accounting for proceeds from the Series D convertible preferred stock financing

The net cash proceeds from the Series D convertible preferred stock financing were $725,000. As the Company did not have sufficient authorized capital for the issuance of the shares underlying the Series D convertible preferred stock at the time of issuance, equity treatment was not permitted under GAAP. The Series D convertible preferred stock was classified as a derivative liability on the Company’s interim consolidated balance sheet as of the previous quarter ended January 31, 2013. Due to the redemption provision in the event that an increase in the Company’s authorized capital was not approved by the stockholders, the Series D convertible preferred stock was reported at that date at its face value of $750,000. Upon the stockholder approval of the increase in authorized capital on March 28, 2013, the Series D convertible preferred stock met the criteria for equity classification and was reclassified as equity at its then face value of $750,000. During the quarter ended April 30, 2013, 219 shares were converted to common stock and as of April 30, 2013 the remaining 531 shares of Series D convertible preferred stock, having a value of $531,000, are reported on the balance sheet as equity.

The initial “make-whole payments” of $202,500 on the Series D convertible preferred stock were accrued as of the date of the financing and the remaining balance of $143,370 (after conversions) are included in Accounts Payable and Accrued Expenses (see Note 5) at April 30, 2013. The warrants that were issued with the Series D convertible preferred stock were determined to be derivatives and were valued at their estimated fair value of $762,355 as of the date of issuance. The calculation methodologies for the fair values of the derivative warrant liability and the derivative additional investment rights liability are described in Note 10 – Derivative Liabilities below.
