ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

Homeland Security Capital Corporation (the "Company") entered into an Investment
Agreement with Cornell Capital Partners, LP ("Cornell Capital"), dated as of
February 6, 2006, pursuant to which the Company will exchange with Cornell
Capital 1,000,000 shares of Series G Convertible Preferred Stock (the "Series G
Preferred Shares") for 450,000,000 shares of the Company's common stock, par
value $0.001 per share (the "Common Stock"), owned by Cornell Capital. Each
share of Series G Preferred Shares shall be convertible, at Cornell Capital's
discretion, into 450 shares of the Common Stock. The Series G Preferred Shares
are senior to all Common Stock and all series of preferred stock of the Company.
Each share of Series G Preferred Share will have a liquidation preference of
$0.10 plus any accrued and unpaid dividends. The holders of Series A Preferred
Shares are not entitled to receive any dividends. The Company will pay a $10,000
structuring fee to Yorkville Advisors Management, LLC in connection with the
transaction.

In connection with the Investment Agreement, the Company entered into an
Investor Registration Rights Agreement with the Cornell Capital pursuant to
which the company agreed to file a registration statement covering the resale of
shares of Common Stock issuable upon the conversion of the Series G Preferred
Shares. The Company also filed a Certificate of Designation with the State of
Delaware amending its certificate of incorporation to include the rights and
terms of the Series G Preferred Shares.

The foregoing is a summary of the terms and conditions of the Investment
Agreement, the Certificate of Designation and the Investor Registration Rights
Agreement and does not purport to be complete. The foregoing is also qualified

ITEM 2.03 CREATION OF A DIRECT FINANCIAL OBLIGATION

The Company entered into a Securities Purchase Agreement with Cornell Capital,
dated as of February 6, 2006, which provided for the purchase by Cornell Capital
of a Convertible Debenture (the "Debenture") in the amount of $4,000,000, which
Debenture is convertible into Common Stock.

The conversion price of the Debenture shall be equal to the lesser of (1) $0.01
or (2) a ten percent discount to the lowest daily volume weighted average price
of the Common Stock for the thirty days preceding conversion. Cornell Capital
will be entitled to convert the Debenture at a conversion price into Common
Stock, provided that Cornell Capital cannot convert into shares of Common Stock
that would cause Cornell Capital to own more than 4.9% of the issued and
outstanding Common Stock.

The Debenture will bear interest at 5% per annum and the principal amount will
be payable on the third anniversary of the effective date of the Debenture. If
the Common Stock is trading below the conversion price, the Company may redeem
the Debenture at any time upon the payment of a redemption premium equal to
twenty percent of the amounts redeemed.

Pursuant to a Security Agreement between the Company and Cornell Capital, the
Company's obligations under the Debenture are secured by a pledge of all of its
assets.

Pursuant to the Securities Purchase Agreement, the Company will pay a commitment
fee of $400,000 and $20,000 in structuring fees and diligence fees, all to
Yorkville Advisors Management, LLC. Accordingly, the Company will receive net
proceeds of approximately $3,580,000 upon issuance of the Debenture. The Company
will also issue to Cornell Capital 50,000,000 shares of the Common Stock
pursuant to this transaction.
