            1.2.2 VENTURI STOCK. As additional consideration for the Shares,
Buyer shall issue to Sellers Ninety-One Thousand Five Hundred (91,500) shares of
Buyer's authorized but unissued $0.001 par value common stock. Said shares shall

issued to each of the Sellers individually.

            1.2.3 ESCROW AND CERTIFICATES. The Venturi Shares shall be subject
to forfeiture if Sellers breach certain of the representations or 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 forth in the
Restated Global Escrow Agreement, as amended. The Venturi Shares shall be held
by Escrow Agent pursuant to the terms of the Restated Global Escrow Agreement,
as amended. The certificates representing the Venturi Shares shall contain, for
so long as the Venturi Shares are held in escrow, a legend in substantially the
following form:

        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO FORFEITURE AND
        ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, INCLUDING AN AGREEMENT
        BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THE SHARES REPRESENTED BY

      UNDER THE SECURITIES LAWS OF ANY STATE (THE "LAW"). SUCH SECURITIES HAVE
      BEEN ACQUIRED FOR INVESTMENT AND NEITHER SAID SHARES NOR ANY INTEREST
      THEREIN MAY BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE
      REGISTRATION STATEMENT FOR THE SHARES UNDER THE ACT AND QUALIFICATION
      UNDER THE LAW OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION
      THAT SUCH REGISTRATION AND QUALIFICATION ARE NOT REQUIRED AS TO SAID SALE

Sellers represent the following to Purchaser in order to establish exemptions
from registration under Federal and state securities laws. Sellers are acquiring
the Shares for their own

<PAGE>

account, for investment, and not for resale in connection with any distribution
thereof. Sellers have such knowledge and experience in business and financial
matters that they are capable of evaluating 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 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.

        1.5 CLOSING DELIVERIES.

            Closing Date.

2.  REPRESENTATIONS AND WARRANTIES OF SELLERS

    To the best of their individual and collective knowledge and belief, Sellers
represent and warrant to Buyer as follows:

        2.1 ORGANIZATION AND GOOD STANDING. (a) the Company is a corporation
duly organized, validly existing, and in good standing under the laws of the
State of Colorado, 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

<PAGE>

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 investor"
as such term is defined in Rule 501(a) under the Securities Act of 1933, as
amended, (the "Securities Act") and the rules and regulations promulgated
thereunder.

        2.4 CAPITALIZATION. The authorized capital stock of the Company consists
of 10,000 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 to any
purported Encumbrance appears upon any certificate representing equity
securities of the Company. All of the outstanding equity securities of the
Company have been duly authorized and validly issued and are fully paid and
nonassessable. There are no Contracts relating to the issuance, sale, or
transfer of any equity securities or other securities of the Company. None of
the outstanding equity securities or other securities of the Company was issued
in violation of the Securities Act or any state law regulating the sale and
issuance of securities. the Company does not own, nor does it have any Contract
to acquire, any equity securities or other securities of any other business or
any direct or indirect equity or ownership interest in any other business.

        2.5 FINANCIAL STATEMENTS. Sellers have delivered to Buyer unaudited
balance sheets of the Company as of January 31, 2000 (the "Balance Sheet"), and
the related unaudited statements of income, changes in stockholders' equity, and
cash flow for each of the fiscal years 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. See Exhibit J.

        2.6 BOOKS AND RECORDS. The books of account, minute books, stock record
books, and other records of the Company, all of which have been made available
to Buyer, are complete and correct and have been maintained in accordance with
sound business practices. The minute books of the Company contain accurate and
complete records of all meetings held of, and corporate action taken by, the
stockholders, the Boards of Directors, and committees of the Boards of Directors
of the Company. At the Closing, all of those books and records will be in the
possession of the Company.

        2.7 TITLE TO PROPERTIES; ENCUMBRANCES. Sellers have delivered to Buyer a
complete and accurate list of all real and personal property interests owned by
the Company.

<PAGE>

the Company owns all the properties and assets that have been disclosed to
Buyer. All material properties disclosed as being owned by the Company are owned
free and clear of all liens and encumbrances except as previously disclosed in
writing to Buyer.

        2.8 CONDITION AND SUFFICIENCY OF ASSETS. To the best of Sellers'
knowledge, except as set forth in Exhibit B, the Company' property and assets
are in good operating condition and repair, and are adequate for the uses to
which they are being put, and none of such property and assets are in need of
maintenance or repairs except for ordinary, routine maintenance and repairs that
are not material in nature or cost. The property and assets of the Company are
sufficient for the continued conduct of the Company' business after the Closing
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
(collectively, the "Accounts Receivable") represent valid obligations arising
from sales actually made or services actually performed in the ordinary course
of business. To the best of Sellers' knowledge, unless paid prior to the Closing
Date, the Accounts Receivable are or will be as of the Closing Date current and
collectible. Absent any unforeseen events, each of the Accounts Receivable
historically has been collected in full within ninety days after the day on
which it first becomes due and payable. Except as may be set forth on Exhibit C
referred to below, there is not any pending, or to Sellers' knowledge
threatened, contest or claim challenging the validity of any of the Accounts
Receivable.

        2.10 NO UNDISCLOSED LIABILITIES. Except as may be set forth in Exhibit
D, the Company has no liabilities or obligations of any nature (whether known or
unknown and whether absolute, accrued, contingent, or otherwise) except for
liabilities or obligations reflected or reserved against in the Balance Sheet
and current liabilities incurred in the ordinary course of business.

        2.11 TAXES. To the best of Sellers' knowledge the Company has filed
or caused to be filed within the past five (5) years all tax returns that are
or were required to be filed by or with respect to the Company, pursuant to
applicable laws and regulations (except use tax returns). Sellers have
delivered or made available to Buyer copies of all such tax returns filed
since 1997. To the best of Sellers' knowledge, all tax returns filed by the
Company are true, correct, and complete. Sellers agree to cooperate in the
event Buyer makes an election under Reg. Section 1.338(h)(10)-1T. The Parties
agree to use the book value of the inventory of the corporation per the
financial information provided under Section 2.51 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. Sellers will be responsible for taxes on income earned only
through 1/31/00. Kreisman, Wolach & Williams, P.C. will prepare said
corporate return through 1/31/00.

        2.12 NO MATERIAL ADVERSE CHANGE. To the best of Sellers' knowledge,
since the date of the Balance Sheet, there has not been any material adverse
change in the business,

<PAGE>

operations, properties, prospects, assets, or condition of the Company, and no
event has occurred or circumstance exists that may result in such a material
adverse change.

        2.13 CONTRACTS AND EMPLOYEE BENEFITS. Except as may be set forth in
Exhibit E, the Company is not a party to any contract or agreement that involves
annual payments by the Company in excess of $25,000, other than in the ordinary
course of business. The consummation of the transaction contemplated herein will
not result in the termination of any material agreement or contract to which the
Company is a party, nor give any party thereto the right to cancel or terminate
any such contract or agreement.

        2.14 ERISA MATTERS. See Special Provisions, Exhibit F.

        2.15 COMPLIANCE WITH LEGAL REQUIREMENTS. Except as may be set forth on
Exhibit G, the Company has not received any notice of any violation of any laws
or regulations that are or were applicable to it or to the conduct or operation
of its business or the ownership or use of any of its assets, which violation
has not been cured as of the Closing Date, and to the best knowledge of Sellers,
the Company is in full compliance with all such laws or regulations.

        2.16 GOVERNMENTAL AUTHORIZATIONS. the Company has obtained all
governmental authorizations and permits that are necessary to permit the Company
to lawfully conduct and operate its business in the manner currently conducted.
See Exhibit E.

        2.17 LEGAL PROCEEDINGS. Except as disclosed in Exhibit H, there is no
material lawsuit or legal or administrative or regulatory proceeding or
investigation pending against the Company, or, to the best knowledge of Sellers,
threatened against the Company.

        2.18 ABSENCE OF CERTAIN CHANGES AND EVENTS. Except as may be set forth

not, and will cause the Company not to, without the prior consent of Buyer, take

Company becomes aware of any fact or condition that causes or constitutes a
Breach of any of Sellers' representations and warranties as of the date of this
Agreement, or if such Seller or the Company becomes aware of the occurrence
after the date of this Agreement of any fact or condition that would (except as
expressly contemplated by this Agreement) cause or constitute a Breach of any
such representation or warranty had such representation or warranty been made as
of the time of occurrence or discovery of such fact or condition. Should any
such fact or condition require any change in this Agreement or the Exhibits
attached to this Agreement, Sellers will promptly deliver to Buyer a supplement
to this Agreement or the Exhibits attached hereto specifying such change. During
the same period, each Seller will promptly notify Buyer of the occurrence of any
Breach of any covenant of Sellers in this Section or of the occurrence of any

        4.6 PAYMENT OF INDEBTEDNESS BY RELATED PERSONS. Except as expressly
provided in this Agreement, Sellers will cause all indebtedness owed to the
Company by either Seller or any related person of either Seller to be paid in

compliance with, any such representation, warranty, covenant, or obligation. The
