                              FIRST PROMISSORY NOTE

US $6,337,000                                                 December 29, 1999

     IAT Multimedia, Inc. (the "Purchaser") hereby promises to pay to Gruppo
Spigadoro N.V. (the "Seller") or registered assignees, by wire transfer of
immediately available funds, in lawful currency of the United States of America,
at an account to be designated in writing by the Seller, the principal amount of
SIX MILLION THREE HUNDRED THIRTY-SEVEN THOUSAND US DOLLARS ($6,337,000)
together with interest on such principal amount at the Applicable Interest Rate
(as defined below), calculated on the basis of a 360 day year compromised of
twelve 30 day months, per annum from the date hereof to the Maturity Date (as
defined below). All terms not otherwise defined herein shall have the meaning
ascribed to them in that certain Stock Purchase Agreement (the "Agreement"),
dated as of November 3, 1999, by and between the Seller and the Purchaser. As
used herein, "Applicable Interest Rate" means a rate of interest per annum equal
to 5% provided that in no event shall the rate of interest hereunder exceed the
rate permitted by applicable laws. If any amount of principal or interest on or
in respect of this note (hereinafter, the "First Promissory Note") becomes due
and payable on any date which is not a Business Day, such amount shall be
payable on the next succeeding Business Day. This First Promissory Note is the
Promissory Note referred to in Schedule 2.2, item #1 of the Agreement.

     1. Maturity Date. As used herein, the term "Maturity Date" shall mean the
earlier (i) of December 31, 2000 or (ii) the completion of a public offering by
the Purchaser in which the Purchaser realizes at least US $20 million of net
proceeds.

     2. Prepayment. The Purchaser may, at any time, but shall not be required
to, prepay, in whole or in part, amounts due under this First Promissory Note,
provided that such prepayment shall include all principal and accrued interest
as of the date of such prepayment.

     3. Conversion of Promissory Note. (a) This First Promissory Note shall be
convertible into shares of Purchaser Common Stock at the option of the
Purchaser, in whole or in part, at any time and from time to time, at a
conversion price equal to the greater of $2.50 or 85% of the average closing
price of Purchaser Common Stock as reported by the primary stock market or
exchange on which the Purchaser Common Stock is traded for the five (5) trading
days prior to a notice of conversion (the "Conversion Notice"). Each Conversion
Notice shall be in writing and shall specify the principal amount of the note to
be converted and the date on which such conversion is to be effected, which date
may not be prior to the date such Conversion Notice is deemed to have been
delivered hereunder (the "Conversion Date"). If no Conversion Date is specified
in the Conversion Notice, the Conversion Date shall be the date that such
Conversion Notice is deemed delivered hereunder. Any Conversion Notice given
shall be irrevocable. If the Purchaser is requiring conversion of less than all
of the principal amount represented by this First Promissory Note, the Purchaser
shall promptly deliver to the Seller a new note for such principal amount as has
not been converted.

     (b) The number of shares so delivered under (a) above shall be further
adjusted by the Board of Directors of the Purchaser or, an authorized committee
thereof, to reflect any issuance of new stock, stock dividend, common stock
split, share combination, exchange of shares, merger, consolidation,
recapitalization, separation, reorganization, liquidation or extraordinary
dividend or similar transaction payable in stock of the Purchaser all for the
purpose of providing dilution protection for the Seller.

     4. Successors and Assignees. The terms of this First Promissory Note shall
be binding upon and inure to the benefit of and be enforceable by the respective
successors and permitted assignees of the Purchaser and the Seller, and,
enforceable by any holder or holders of this First Promissory Note; provided
that the rights, obligations, covenants and agreements of the Purchaser under
this First Promissory Note may not be assigned or delegated, as applicable,
without the written consent of the Seller. In the event of any such transfer and
assignment of this First Promissory Note, the Purchaser shall, upon surrender of
this First Promissory Note to the Purchaser, execute and deliver in exchange
therefor a new note. Each such new note shall be dated so that there will be no
loss of interest on the surrendered First Promissory Note and registered in the
name of such person as the Seller or other holder of the surrendered First
Promissory Note may request.
