ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On February 8, 2006 the Company entered into a Series A Convertible Preferred
Stock Purchase Agreement (the "Purchase Agreement") with Nexus Technologies
Group, Inc. ("Nexus"). Pursuant to the Purchase Agreement, the Company purchased
3,400,000 shares of Nexus Series A Convertible Preferred Stock (the "Preferred
Shares") for an aggregate purchase price of $3,400,000 (the "Offering"). The
Company also committed to purchase an additional 6,400,000 Preferred Shares, in
one or more transactions, at a purchase price of $1.00 per share at any time
prior to February 8, 2008.

Each Preferred Share will accrue dividends cumulatively at the rate of eight
percent (8%) per annum and is convertible into one (1) share of the Nexus common
stock at any time by the Company at a conversion price of $1.00 per share,
subject to adjustment for stock dividends, stock splits, and similar events.
Each Preferred Share will be entitled to one vote as if converted into Nexus
common stock. The holders of the outstanding Preferred Shares, as a class, will
have the right to elect a majority of the board of directors of Nexus. Each
Preferred Share will have a liquidation preference of $1.00 per share plus any
accrued and unpaid dividends.

Immediately following the Merger (described below) and the Offering, the Company
will control 82.1% of the voting power of Nexus.

The foregoing description of the Purchase Agreement is qualified in its entirety
by reference to the actual terms of the Purchase Agreement, a copy of which is
attached hereto as Exhibit 10.2 and is incorporated by reference herein in its
entirety.

ITEM 2.01. COMPLETION OF ACQUISITION.

On February 8, 2006, Nexus, a subsidiary of the Company, completed its
acquisition of Corporate Security Solutions, Inc., a Pennsylvania corporation
("CSS") pursuant to the terms of an Agreement and Plan of Merger (the
"Agreement"), dated February 8, 2006, by and among Nexus Technologies Group,
Inc., Corporate Security Solutions, Inc., CSS Acquisition, Inc. and certain
other persons named therein.

Pursuant to the Merger Agreement, CSS merged with and into CSS Acquisition,
Inc., a wholly owned subsidiary of Nexus, (the "Merger") with CSS Acquisition
the surviving the Merger. The stockholders of CSS will receive an aggregate of
3,675,000 shares of Nexus common stock in exchange for all of the issued and
outstanding CSS common stock. Of these shares, 3,000,000 are deemed restricted
stock and are subject to vesting and performance provisions.

The Agreement contains representations and warranties the parties made to each
other as of specific dates. The assertions embodied in those representations and
warranties were made solely for purposes of the contract between the parties to
the Agreement and may be subject to important qualifications and limitations
agreed by the parties in connection with negotiating its terms. Moreover,
certain representations and warranties may not be accurate or complete as of any
specified date because they are subject to a contractual standard of materiality
different from those generally applicable to shareholders or were used for the
purpose of allocating risk between the parties rather than establishing matters
as facts. For the foregoing reasons, you should not rely on the representations
and warranties as statements of factual information.

The foregoing description of the Agreement is qualified in its entirety by
reference to the actual terms of the Agreement, a copy of which is attached
hereto as Exhibit 10.1 and is incorporated by reference herein in its entirety.
