                            STOCK PURCHASE AGREEMENT

       THIS STOCK PURCHASE AGREEMENT (the "Agreement") is dated this 30th day of
December, 1998, among UNICO, INC., a Delaware corporation (the "Seller"), NEXT
GENERATION MEDIA CORP., a Nevada corporation (the "Buyer") and T.C. EQUITIES,
LTD., a Bahamian investment company ("T.C. Equities").

                                    RECITALS

       A.     The Seller desires to issue to Buyer 1,800,000 shares of common
stock, par value $0.01 ("Common Stock") of Seller on the terms and conditions
set forth below.

       B.     The Buyer desires to buy from Seller such shares of Common Stock,
on the terms and conditions set forth below.

       C.     The Buyer has assigned its right to receive the Common Stock
purchased herein to T.C. Equities.

       NOW, THEREFORE, in consideration of the foregoing, and for other
consideration, the receipt and sufficiency of which are acknowledged, the
parties agree as follows:

       1.     Purchase and Sale.

       The Seller agrees to issue and does hereby unconditionally and
irrevocably sell, convey, assign and transfer to T.C. Equities, 1,800,000 shares
of Common Stock (the "Purchased Securities") for a price of One Hundred Eighty
Thousand Dollars and No Cents ($180,000.00) and Buyer's obligation to advance
certain other funds to Seller in an amount not less than $54,000 (the "Purchase
Price"). Buyer has paid the Seller $170,000 of the Purchase Price in the form of
cancellation of indebtedness in the same amount owed to Buyer by Seller and
shall have advanced the remaining $54,000, an additional $10,000 of which shall
be forgiven, on or before the effective date of the merger between United
Marketing Merger Corp., a subsidiary of Buyer and United Marketing Solutions
Inc., a subsidiary of Seller.

       2.     Representations and Warranties.

       The Buyer represents and warrants to the Seller as follows:

              (a)    The Buyer has the financial ability to bear the economic
       risk of its investment in the Purchased Securities, has adequate means of
       providing for its current needs and contingencies, and has no need for
       liquidity in its investment in the Purchased Securities. Further, alone
       or with representatives or advisors, the Buyer has such knowledge and
       experience in financial and business matters that it is capable of
       evaluating the merits and risks of the transactions contemplated by this
       Agreement.

              (b)    The Buyer has had the opportunity to question various
       officers of the Seller regarding its assets, business and prospects, and
       has received satisfactory answers to all such questions. No
       representative of the Seller has made any representation regarding the
       current or future value of the Purchased Securities, and the Buyer has
       not relied on any such representation in deciding to undertake the
       transactions contemplated by this Agreement. In making the decision to
       invest in the Seller, the Buyer has relied solely upon independent
       investigations made by him or on his behalf.

              (c)    The Purchased Securities will be acquired by the Buyer in
       good faith for investment purposes only, and are not being acquired with


<PAGE>   2


       a view to, or for, a "distribution" thereof within the meaning of the
       Securities Act of 1933 (the "Securities Act"). The Buyer is aware that
       there is presently no market for the resale of the Purchased Securities
       and that no market may exist in the future for such resale, and the Buyer
       understands that the Purchased Securities are a speculative investment
       that involves a substantial risk and the Buyer may lose his entire
       investment.

              (d)    The Buyer understands that the Purchased Securities have
       not been registered under the Securities Act, and agrees that none of the
       Purchased Securities may be sold, offered for sale, transferred, pledged,
       hypothecated or otherwise disposed of except in compliance with the
       Securities Act. The Buyer will not, directly or indirectly, voluntarily
       offer, sell, transfer, pledge, hypothecate or otherwise dispose of (or
       solicit any offers to purchase or otherwise acquire or take a pledge of)
       any Purchased Securities unless (i) registered pursuant to the provisions
       of the Securities Act, or (ii) an exemption from registration is
       available under the Securities Act. The Buyer has been advised that the
       Seller does not have an obligation, and does not intend, to cause any
       Purchased Securities to be registered under the Securities Act, or to
       take any action necessary for the Buyer to comply with any exemption
       under the Securities Act that would permit such Purchased Securities to
       be sold by the Buyer. The Buyer further understands that, if the Buyer
       desires to sell or transfer all or any part of the Purchased Securities,
       the Seller may require the Buyer's counsel to provide a legal opinion
       that the transfer may be made without registration under the Securities
       Act. The Buyer understands that the Purchased Securities will bear
       substantially the following restrictive legend:

              THE SHARES OF STOCK EVIDENCED HEREBY HAVE NOT BEEN REGISTERED
              UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("THE ACT") NOR
              QUALIFIED UNDER THE SECURITIES LAWS OF ANY STATES, AND HAVE BEEN
              ISSUED IN RELIANCE UPON EXEMPTIONS FROM SUCH REGISTRATION AND
              QUALIFICATION FOR NONPUBLIC OFFERINGS. ACCORDINGLY, THE SALE,
              TRANSFER, PLEDGE, HYPOTHECATION, OR OTHER DISPOSITION OF ANY SUCH
              SECURITIES OR ANY INTEREST THEREIN MAY NOT BE ACCOMPLISHED EXCEPT
              PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND
              QUALIFICATION UNDER APPLICABLE STATE SECURITIES LAWS, OR PURSUANT
              TO AN OPINION OF COUNSEL SATISFACTORY IN FORM AND SUBSTANCE TO THE
              COMPANY TO THE EFFECT THAT SUCH REGISTRATION AND QUALIFICATION ARE
              NOT REQUIRED.

              (e)    The Buyer affirms that all of the representations and
       warranties of the Buyer contained herein, and all information furnished
       by the Buyer to the Seller, are true, correct and complete in all
       respects.

              (f)    T.C. Equities makes the same representations and warranties
       of the Buyer in Sections 2(a), (b), (c), (d) and (e) as if restated 
       herein and further represents and warrants that it is as an "accredited
       investor" as that term is defined in Regulation D under the Securities
       Act.

       3.     Indemnification by Buyer/T.C. Equities.

       The Buyer agrees to indemnify and hold the Seller harmless against, and
will reimburse Seller on demand for, any payment, loss, cost or expense
(including reasonable attorney's fees and reasonable costs of investigation
incurred in defending against such payment, loss, cost or expense or claim
therefor) made or incurred by or asserted against the Seller in respect of any
omission, misrepresentation or breach of warranty on the part of Buyer contained
in this Agreement. T.C. Equities agrees to indemnify and hold the Seller
harmless against, and will reimburse Seller on demand for, any payment,


<PAGE>   3


loss, cost or expense (including reasonable attorney's fees and reasonable costs
of investigation incurred in defending against such payment, loss, cost or
expense or claim therefor) made or incurred by or asserted against the Seller in
respect of any omission, misrepresentation or breach of warranty on the part of
T.C. Equities contained in this Agreement.

       4.     Taxes and Expenses.

       The Buyer covenants and agrees to pay all taxes, if any, on the transfer
to T.C. Equities of the Purchased Securities. Each party shall be individually
responsible for and shall personally pay all costs, liabilities and other
obligations incurred by it or him in connection with the performance of and
compliance with the transactions contemplated by this Agreement.

other than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each term, covenant or condition shall be valid and
enforced to the fullest extent permitted by law. Upon determination that any
such term is invalid, illegal or unenforceable, the parties hereto shall amend
this Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner.
