Item 1.01 Entry into a Material Definitive Agreement.

On November 30, 2007, we entered into a securities purchase agreement with Xentenial Holdings Limited whereby Xentenial agreed to purchase up to $1,150,000 of secured convertible debentures. We announced the agreement in a Form 8-K filed December 5, 2007. In that same Form 8-K, we announced that we had sold one convertible debenture to Xentenial Holdings pursuant to the securities purchase agreement in the principal amount of $422,000 and issued 225 million five year warrants.

On January 18, 2008, by way of a letter agreement, we amended the interest rate of the $422,000 convertible debenture issued on November 30, 2007 from 10% to 12% as the term sheet for the transaction reflected an interest rate of twelve percent (12%), but the debenture contained an interest rate of ten percent (10%).

Pursuant to the terms of this security purchase agreement, we sold one additional secured convertible debenture on January 18, 2008 to Xentenial Holdings in the principal amount of $392,000 and issued 228 million five year warrants exercisable into shares of our Common Stock at $0.0298 per share. We received net proceeds of $350,000 on January 18, 2008 after paying a $42,000 monitoring fee to Yorkville Advisors, LLC. Under the terms of this secured convertible debenture, we are required to repay principal, together with accrued interest calculated at an annual rate of twelve percent (12%), on or before January 17, 2011. Interest may be paid either in cash or in shares of our common stock valued at the closing bid price on the trading day immediately prior to the date paid, at our option. Subject to a restriction described below, all or any part of principal and interest due under the secured convertible debenture may be converted at any time at the option of the holder into shares of our common stock. The conversion price in effect on any conversion date shall be equal to the lesser of

(a)

$0.0573 or;

(b)

eighty percent (80%) of the lowest volume weighted average price of our common stock during the thirty (30) trading days immediately preceding the conversion date as quoted by Bloomberg, LP.

The conversion price is subject to adjustment in the event we issue any shares of our common stock (or any rights, options, warrants or securities convertible or exercisable into shares of our common stock) at a price per share less than the conversion price then in effect, in which event, subject to certain agreed exceptions, the conversion price will be reduced to the lower purchase price.

The secured convertible debenture contains a contractual restriction on beneficial share ownership. It provides that the holders may not convert the convertible debenture, or receive shares of our common stock as payment of interest, to the extent that the conversion or the receipt of the interest payment would result in such holder, together with its respective affiliates, beneficially owning in excess of 4.99% of our then issued and outstanding shares of common stock. This beneficial ownership limitation may be waived by the holder upon not less than 65 days’ notice to us.

Interest will be calculated on the basis of a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law. Interest is to be paid on the maturity date (or sooner as provided in the convertible debentures) in cash or shares of our common stock (valued at the closing bid price on the trading day immediately prior to the date paid) at our option.

An event of default will occur under the convertible debenture if any of the following occurs:

·	Any default (not waived by the holder) in the payment of the principal of, interest on or other charges in respect of the convertible debentures;

·	We or any of our subsidiaries become bankrupt or insolvent;

·	We or any of our subsidiaries default in any of its obligations under any other indebtedness in an amount exceeding $100,000;

Our common stock ceases to be quoted for trading or listed for trading on any of the Nasdaq OTC Bulletin Board, the New York Stock Exchange, American Stock Exchange, the NASDAQ Capital Market or the NASDAQ National Market) and is not again quoted or listed for trading on any primary market within 5 trading days of such delisting;

·	We or any subsidiary experiences a change of control;

We fail to use our best efforts to file, within thirty (30) days of demand by the Investors and provided that at least 30 days have passed since any other registration statementfiled by us has been declared effective by the SEC, with the SEC a registration statement on Form S-1 or SB-2 (or, if the Company is then eligible, on Form S-3) under the Securities Act ;

-2-

·	If the effectiveness of the registration statement lapses for any reason or the holder of the 10% convertible debenture is not permitted to resell the underlying shares of common stock, in either case, for more than five trading days or an aggregate of eight trading days;

·	We fail to deliver common stock certificates to a holder prior to the fifth trading day after a conversion date or we fail to provide notice to a holder of our intention not to comply with requests for conversions of the convertible debentures;

·	We fail to deliver the payment in cash pursuant to a “buy-in” within three days after notice is claimed delivered; or;

·	We fail to observe or perform any other material covenant or agreement contained in or otherwise materially breach or default under any other provision of the convertible debenture which is not cured within the applicable cure periods.

Upon an event of default, the full principal amount of the convertible debentures, together with accrued and unpaid interest will become, at the holder’s election, immediately due and payable in cash or, at the election of the holder, shares of our common stock. Furthermore, in addition to any other remedies, the holder will have the right to convert the convertible debenture at any time after an event of default or the maturity date at the then effective conversion price. If an event of default occurs, we may be unable to immediately repay the amount owed, and any repayment may leave us with little or no working capital in our business.

In the event of any issuances of shares of common stock or rights, options, warrants or securities convertible or exercisable into common stock at a price per share of common stock less than the conversion price of the convertible debentures, the conversion price of such convertible debentures will be reduced to the lower purchase price. In addition, the conversion price of the convertible debentures will be subject to adjustment in connection with any subdivision, stock split, combination of shares or recapitalization. No adjustment will be made as a result of issuances (or deemed issuances) of securities or interests upon the conversion, exchange or exercise of any right, option, warrant obligation or security outstanding immediately prior to the date of execution of the security purchase agreement and exercises of options to purchase shares of common stock issued for compensatory purposes pursuant to any of our stock option or stock purchase plans.
