warranties in this Agreement, or if certain of the representations made by
Sellers in this Agreement turn out to be untrue, as shall be more fully set

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO FORFEITURE AND
     ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, INCLUDING AN AGREEMENT

     THIS CERTIFICATE THAT THE SHARES MAY NOT BE OFFERED OR SOLD FOR A CERTAIN

the risks of obtaining the Shares. Sellers understand the speculative nature of
the Shares. Sellers have adequate net worth and means to provide for their
current needs and to

<PAGE>

sustain a complete loss of their investment. Sellers have no need of liquidity
of their investment. Sellers understand that at present only a limited public
market exists, and that a more general public market may never exist, for the
Shares and that the Purchaser is under no obligation to provide a market for the
Shares.

          1.3 CONSENT TO DILUTION. Sellers understand that Purchaser plans to
acquire other businesses and assets by issuing stock, and that Purchaser may
issue shares of its stock for other reasons in the future. Sellers understand
and consent that future issuance of stock will dilute Sellers' proportionate
ownership of Purchaser.

          1.4 CLOSING. The purchase and sale (the "Closing") provided for in
this Agreement will take place at a time, place and date agreed to mutually by
the Parties.

State of Florida, with full corporate power and authority to conduct its
business as it is now being conducted, to own or use the properties and assets
that it purports to own or use, and to perform all its obligations under
applicable contracts. The Company is duly qualified to do business as a foreign
corporation and is in good standing under the laws of each state or other
jurisdiction in which either the ownership or use of the properties owned or
used by it, or the nature of the activities conducted by it, requires such
qualification.

          2.2 AUTHORITY. This Agreement constitutes the legal, valid, and
binding obligation of Sellers, enforceable against Sellers in accordance with
its terms. Sellers have the absolute and unrestricted right, power, authority,
and capacity to execute, deliver and perform their obligations under this
Agreement.

          2.3 NO CONFLICT. Neither the execution and delivery of this Agreement
nor the consummation or performance of any of the contemplated transactions by
Sellers will violate or constitute a default under any mortgage, indenture, deed
of trust, lease, contract, agreement, license or other instrument or any order,
judgement or ruling of any governmental authority to which either Seller is
subject, or to the best knowledge of Sellers, any of the property of the Company
is bound, or result in the creation of any mortgage, pledge, lien, charge or
encumbrance upon any of the assets of the Company or the loss of any license or
other contractual right with respect thereto, except in each case for any of the
foregoing which is not, individually or in the aggregate, material to the
Company.

     Except as may be set forth in Exhibit A, no Seller or the Company is or
will be required to give any notice to or obtain any consent from any person in
connection with the execution and delivery of this Agreement or the consummation
or performance of the transaction contemplated hereby.

     Sellers are acquiring the Promissory Notes and the shares of Buyer's common
stock for their own account and not with a view to their distribution within the
meaning of Section 2(11) of the Securities Act. Each Seller is an "accredited

consists of 50,000 authorized shares of common stock, par value $0.00 per share,
of which 2,000 shares are issued and outstanding and constitute the Shares.
Sellers are and will be on the Closing Date the record and beneficial owners and
holders of the Shares, free and clear of all Encumbrances. Martin owns 1,000 of
the Shares and Peterman owns 1,000 of the Shares. No legend or other reference

balance sheet of the Company from the period ending 1/31/2000 (the "Balance

stockholders' equity, and cash flow for each of the fiscal year then ended. Such
financial statements and notes were prepared in accordance with GAAP, subject,
in the case of interim financial statements, to normal recurring year-end
adjustments (the effect of which will not, individually or in the aggregate, be
materially adverse) and the absence of notes (that, if presented, would not
differ materially from those included in the balance sheet); the financial
statements referred to in this Section reflect the consistent application of
such accounting principles throughout the periods involved, except as disclosed
in the notes to such financial statements. No financial statements of any person
or entity other than the Company are required by GAAP to be included in the
consolidated financial statements of the Company.

          2.6 BOOKS AND RECORDS. The books of account, minute books, stock

in substantially the same manner as conducted prior to the Closing.

          2.9 ACCOUNTS RECEIVABLE. All accounts receivable of the Company that
are reflected in the accounting records of the Company as of the Closing Date

have delivered or made available to Buyer copies of all such tax returns
filed since 1997. To the best of Seller's knowledge, all tax returns filed by
the Company are true, correct, and complete. The Parties agree to use the
book value of the inventory of the corporation per the financial information
provided under Section 2.5 as the fair market value of the inventory and to
use the amount determined by Seller as the fair market value of the fixed
assets of the corporation on the effective date for all tax purposes. If a
separate corporate tax return is required through January 31, 2000, Kreisman,
Wolach & Williams, P.C. will prepare said corporate return.

or inaccuracy of or compliance with, any such representation, warranty,
covenant, or obligation. The waiver of any condition based on the accuracy of

and obligations.
