ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On November 4, 2005, we sold $340,000 in principal amount of our five-year
convertible debentures to Dutchess Private Equities Fund, II, L.P. (the
"Investor"). These debentures bear interest at 12% per annum. The first $190,000
(less expenses) has been funded with an additional $150,000 to be funded
immediately upon filing of a registration statement with the Securities and
Exchange Commission ("SEC"). Our obligation to repay the investor is secured by
a security agreement which we have granted the Investor. We have pledged all of
our assets to insure repayment of this obligation.

Subject to adjustment as more fully set forth in the Debenture Agreement, the
conversion price of the debenture shall be the lesser of (i) $.27 per share or;
(ii) the lowest closing bid price of the common stock between October 18, 2005
and the date of the filing with the SEC of a registration statement covering the
shares issuable under the debenture.

We also issued to the Investor a warrant to purchase up to total of $85,000
worth of shares of common stock with a strike price equal to the conversion
price of the debenture, as set forth above, on the date of exercise. The warrant
may be exercised for a period of five years and the strike price is subject to
adjustment upon the occurrence of certain events, including, without limitation,
upon our consolidation, merger or sale of all of substantially all of our
assets, a reclassification of our common stock, or any stock splits,
combinations or dividends with respect to our common stock.

We are obligated to file a registration statement within 21 days after the
closing date and are obligated to use our best efforts to cause the SEC to
declare the registration statement effective within 90 days after the filing
date. If we do not file a registration statement with the SEC within 21 days of
the closing date, we are obligated to pay liquidated damages to the Investor in
an amount equal to 2% of the principal amount of the debenture outstanding, pro
rata, for every 15 days which such registration statement has not been filed. In
addition, if the registration statement is not filed by the filing date, the
conversion price of the debenture will decrease by 10% of and continue to
decrease by 10% for each 15 day calendar period the registration statement goes
without filing. If the registration statement is not declared effective within
90 days of the filing date, we are obligated to pay liquidated damages to the
Investor in an amount equal to 2% of the principal amount of the debenture
outstanding, pro rata, for every 30 days which such registration statement has
not been declared effective by the SEC.

Further, on November 4, 2005, we entered into an Investment Agreement with the
Investor. Pursuant to this Agreement, the Investor shall commit to purchase up
to $5,000,000 of our common stock over the course of 36 months ("Line Period"),
after the registration statement (as described below) has been declared
effective by the SEC. The amount that we shall be entitled to request from each
purchase ("Puts"), shall be equal to, at our election, either (i) $100,000 or;
(ii) 200% of the averaged daily volume (U.S market only) ("ADV") of our common
stock for the three (3) trading days prior to the applicable put notice date,
multiplied by the average of the 3 daily closing bid prices immediately
preceding the put date. The put date shall be the date that the Investor
receives a put notice of draw down by us of a portion of the Line. The purchase
price shall be set at 93% of the lowest closing highest posted bid price of the
common stock during the pricing period. The pricing period shall be the five (5)
consecutive trading days immediately after the put date. There are put
restrictions applied on days between the put date and the closing date with
respect to that particular Put. During this time, we shall not be entitled to
deliver another put notice. We shall automatically withdraw that portion of the
put notice amount, if the purchase price with respect to that Put does not meet
the Minimum Acceptable Price. The Minimum Acceptable Price is defined as 75% of
the closing bid price of the common stock for the ten (10) trading days prior to
the put notice date.

We are obligated to file a registration statement covering the shares of common
stock underlying the Investment Agreement within 15 days after the filing of our
Annual Report on Form 10-KSB for the year ended December 31, 2005. In addition,
we are obligated to use reasonable efforts to have the registration statement
declared effective by the SEC within 90 days after the filing date.

We claim an exemption from the registration requirements of the Act for the
private placement of these securities pursuant to Section 4(2) of the Act and/or
Regulation D promulgated thereunder since, among other things, the transaction
did not involve a public offering, the investors were accredited investors
and/or qualified institutional buyers, the investors had access to information
about the company and their investment, the investors took the securities for
investment and not resale, and we took appropriate measures to restrict the
transfer of the securities.

ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On November 4, 2005, we sold $340,000 in principal amount of our five-year
convertible debentures to Dutchess Private Equities Fund, II, L.P. (the
"Investor"). These debentures bear interest at 12% per annum. The first $190,000

immediately upon filing of a registration statement with the Securities and

a security agreement which we have granted the Investor. We have pledged all of
our assets to insure repayment of this obligation.

Subject to adjustment as more fully set forth in the Debenture Agreement, the
conversion price of the debenture shall be the lesser of (i) $.27 per share or;
(ii) the lowest closing bid price of the common stock between October 18, 2005
and the date of the filing with the SEC of a registration statement covering the
shares issuable under the debenture.

We also issued to the Investor a warrant to purchase up to total of $85,000
worth of shares of common stock with a strike price equal to the conversion
price of the debenture, as set forth above, on the date of exercise. The warrant
may be exercised for a period of five years and the strike price is subject to
adjustment upon the occurrence of certain events, including, without limitation,
upon our consolidation, merger or sale of all of substantially all of our
assets, a reclassification of our common stock, or any stock splits,
combinations or dividends with respect to our common stock.

We are obligated to file a registration statement within 21 days after the

addition, if the registration statement is not filed by the filing date, the
conversion price of the debenture will decrease by 10% of and continue to
decrease by 10% for each 15 day calendar period the registration statement goes
